The system is merely shown and described as being used in the context of skateboards for ease of description and as one of countless examples.

Skateboard

With reference to the figures, a skateboard 200 is presented. Skateboard 200 may be any skateboard, such as, by way of example and not limitation, street skateboards, mini skateboards, longboards, and any other type of skateboard. In the arrangement shown, as one example, skateboard 200 has a top side 202, a bottom side 204, opposing front and back ends 206 (or simply “ends 206”), and opposing left and right sides 208 (or simply “sides 208”). In the arrangement shown, as one example, skateboard 200 is a street skateboard having a deck 210, trucks 212, and wheels 214, among other components as described herein. While skateboard 200 has been described according to the arrangement shown, as one example, any design, arrangement, or configuration of a skateboard may be used and is hereby contemplated for use as skateboard 200.

Deck: In the arrangement shown, as one example, skateboard 200 includes deck 210. Deck 210 is formed of any suitable size, shape, and design and are configured to provide a surface upon which a rider stands when riding skateboard 200. In the arrangement shown, as one example, deck 210 has a top surface 216, a bottom surface 218, opposing front and back ends 220 (or simply “ends 220”), and opposing left and right sides 222 (or simply “sides 222”).

In the arrangement shown as one example, deck 210 may be formed of a single, unitary member that is formed in a manufacturing process such as machining or the like to form a unitary and monolithic member. Deck 210 may be formed of any number of non-metallic materials such as a wooden material, fiberglass, plastic, a composite material, or any other non-metallic material that is customary for use on skateboards.

In the arrangement shown, as one example, when viewed from top side 202, deck 210 is generally in the geometric shape of an obround, however deck 210 may be formed of any other shape or configuration, including a rectangle, an oval, or any other shape. In the arrangement shown, as one example, the front and back ends 220 of deck 210 each form a generally semi-circular end 220 and sides 222 extending from front end 220 to back end 220 in approximate parallel planar spaced relation to each side 222. In the arrangement shown, as one example, when viewed from a left or right side 208, deck 210 is curved up at each end 220 and extends between each end 220 with a generally convex curvature, such that the top surface 216 of deck 210 is higher in the middle than it is near ends 220.

In the arrangement shown, as one example, deck 210 includes holes 224. Holes 224 are formed of any suitable size, shape, and design and are configured to facilitate connection of trucks 212 to deck 210. In the arrangement shown, as one example, holes 224 extend from the top surface 216 of deck 210 through to bottom surface 218 of deck 210. In the arrangement shown, as one example, holes 224 are generally circular in shape, however holes 224 may be formed of any other shape or configuration, including an ovular shape, a square shape, a triangular shape, or any other shape. In the arrangement shown, as one example, holes 224 are configured to receive fasteners 232 of trucks 212. In an arrangement, as an example, holes 224 may be countersunk from the top surface 216 such that the top of each head of fasteners 232 remains below top surface 216 of the deck 210.

While deck 210 has been primarily described with reference to one or more of the arrangements shown, as one example, it will be understood by those skilled in the art that any other configuration of deck 210 may be used in order to provide a surface upon which a rider stands when riding skateboard 200.

Trucks: In the arrangement shown, as one example, skateboard 200 includes trucks 212. Trucks 212 are formed of any suitable size, shape, and design and are configured to connect deck 210 to wheels 214. In the arrangement shown, as one example, skateboard 200 includes a pair of trucks 212, however any other number of trucks may be used depending on the number of wheels 214 necessary for the particular skateboard 200. In the arrangement shown, as one example, trucks 212 include a base plate 226, a hanger 228, and an axle 230.

In the arrangement shown, as one example, truck 212 includes a base plate 226. Base plate 226 is formed of any suitable size, shape, and design and is configured to connect to trucks 212 to bottom surface 218 of deck 210. In the arrangement shown, as one example, base plate 226 is formed of a single, unitary member that is formed in a manufacturing process such as machining, casting, molding, extruding, or the like to form a unitary and monolithic member. Trucks 212 may be formed of any number of metallic materials and any composite thereof or, alternatively, trucks 212 may be formed of any number of non-metallic materials such as a wooden material, fiberglass, plastic, or any other non-metallic materials or composites thereof.

In the arrangement shown, as one example, base plate 226 is shaped in order to conform to bottom surface 218 of deck 210 in order to tightly and closely engage with bottom surface 218 of deck 210. In the arrangement shown, as one example, bottom surface 218 includes openings (not shown) which receive fasteners 232 of trucks 212, which also extend through holes 224 of deck 210. When fasteners 232 of trucks 212 are extending through the openings (not shown) of trucks 212 and through holes 224 of deck 210, base plate 226 is operably connected to deck 210.

In the arrangement shown, as one example, base plate 226 includes a pin (not shown). The pin of base plate 226 is formed of any suitable size, shape, and design and is configured to connect hanger 228 to base plate 226. In the arrangement shown, as one example, the pin of base plate 226 is a generally cylindrical pin which extends downward from the bottom surface of base plate 226. In the arrangement shown, as one example, at the lowest end of the pin, there is a threaded portion which is configured to receive at least one nut (not shown). In the arrangement shown, as one example, the hanger 228 is operably connected to the pin of base plate 226 by placing a first nut onto the threaded portion of the pin, the placing the pin through an opening in the hanger 228, then placing a second nut onto the threaded portion of the pin, thereby securely connecting hanger 228 to the pin of base plate 226. In this way, the pin of base plate 226 connects hanger 228 to base plate 226.

In the arrangement shown, as one example, trucks 212 include hanger 228. Hanger 228 is formed of any suitable size, shape, and design and is configured to connect to base plate 226 and to axle 230. In the arrangement shown, as one example, hanger 228 is a generally elongated member which extends from a first side to a second side. In the arrangement shown, as one example, when viewed from a front or back end 206 of skateboard 200, hanger 228 may be generally triangular in shape, with the elongated section 234 of hanger 228 extending from near one opposing side 208 to near the other opposing side 208 and extending upward to a generally narrower portion which connects to the pin of base plate 226. In the arrangement shown, as one example, the narrower portion of hanger 228 near base plate 226 includes an opening which receives the pin of base plate 226 and secured to the pin using the nuts of base plate 226 as described herein.

In the arrangement shown, as one example, the elongated section 234 of hanger 228, which extends from near one opposing side 208 to near the other opposing side 208 includes a hollow center (not shown) extending all the way through the elongated section 234. The hollow center of the elongated section 234 is formed of any suitable size, shape, and design and is configured to receive axle 230 within the hollow center. In this way, axle 230 extends complete through hanger 228, thereby facilitating connection with both axle 230 and base plate 226.

In the arrangement shown, as one example, trucks 212 include axle 230. Axle 230 is formed of any suitable size, shape, and design and is configured to facilitate connection of wheels 214 to trucks 212. In the arrangement shown, as one example, axle 230 is a generally elongated and cylindrical member. In the arrangement shown, as one example, axle 230 extends from near one opposing side 208 of skateboard 200 to near the other opposing side 208 of skateboard 200. In the arrangement shown, as one example, axle 230 extends a distance slightly longer than the elongated section 234 of hanger 228. In this way, at least a portion of each side of axle 230 extends outward from the elongated section 234 when extended through the hollow center of the elongated section 234 of hanger 228 such that at least one wheel 214 can fit over axle 230 on each opposing side 208 of skateboard 200. In the arrangement shown, as one example, axle 230 includes at least one nut on each side of axle 230 and this nut is configured to securely connect wheels 214 to axles 230. In this way, axle 230 facilitates the connection of wheels 214 to trucks 212.

While trucks 212 have been primarily described with reference to one or more of the arrangements shown, as one example, it will be understood by those skilled in the art that any other configuration of trucks 212 may be used in order to connect deck 210 to wheels 214.

Wheels: In the arrangement shown, as one example, skateboard 200 includes wheels 214. Wheels 214 are formed of any suitable size, shape, and design and are configured to facilitate movement of skateboard 200. In the arrangement shown, as one example, wheels 214 may be any standard or non-standard wheels used on a skateboard, including, by way of example and not limitation, wheels made from a non-metallic material such as polyurethane. In the arrangement shown, as one example, wheels 214 may be formed in a manufacturing process such as molding or the like to form a unitary and monolithic member.

In the arrangement shown, as one example, wheels 214 include bearings 215 which are configured to facilitate rotation of wheels 214 around axles 230 of trucks 212. In this way, wheels 214 are able to rotate while axles 230 of trucks 212 remain stationary. This allows each wheel 214 of skateboard 200 to spin freely as necessary to transfer rotational movement of the wheels to linear movement of the axles 230 to ensure proper travel of skateboard 200. In the arrangement shown, as one example, there are two wheels 214 connected to each axle 230, with one wheel 214 connected on each end of axle 230. In this arrangement, the bearings 215 of wheels 214 allow each wheel on the same axle 230 to spin independently of one another, meaning the wheels 214 may spin at different rates, which allow the skateboard 200 to turn as desired.

In the arrangement shown, as one example, there are four wheels 214, one on each end of each axle 230. That is, in the arrangement shown as one example, there are two wheels 214 per each truck 212 on skateboard 200, and with two wheels 214 near each opposing side 208 of skateboard 200, with one such wheel 214 near the front end 206 and the other wheel 214 near the back end 206 of skateboard 200.

While wheels 214 have been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that any other configuration of wheels 214 may be used in order to facilitate movement of skateboard 200.

Power System

With reference to the figures, a power system 10 for a skateboard (or simply “system 10”) is presented. System 10 is formed of any suitable size, shape, and design and is configured to operably connected to a skateboard 200 and provide power to skateboard 200. In the arrangement shown, as one example, system 10 has a forward end 12, a rearward end 14, and opposing left and right sides 16 (or simply “sides 16”). In the arrangement shown, as one example, system 10 includes a base plate 18, a drive unit 20, a wheel assembly 22, and straps 24, among other components as described herein. While system 10 has been described according to the arrangement shown, as one example, any combination or arrangement may be used and is hereby contemplated for use.

Base Plate:

In the arrangement shown, as one example, system 10 includes base plate 18. Base plate 18 is formed of any suitable size, shape, and design and is configured to facilitate engagement with the skateboard 200 and with drive unit 20. In the arrangement shown, as one example, base plate 18 has a top surface 26, a bottom surface 28, a front end 30, a back end 31, and opposing left and right sides 32 (or simply “sides 32”). In the arrangement shown, as one example, base plate 18 includes a notch 33, compressible members 34, a curved portion 36, a first plate 38, a cover 40, and a second plate 42.

In the arrangement shown, as one example, base plate 18 is formed of a single, unitary member that is formed in a manufacturing process such as machining, casting, extrusion, forming, additive manufacturing, or the like to form a unitary and monolithic member. Alternatively, base plate 18 may be formed of multiple pieces that are connected or assembled to one another through welding, screwing, bolting, friction fitting, or the like. In the arrangement shown, as one example, base plate 18 may be formed primarily of a metallic material such as steel, aluminum, chromium, or any other metallic material, alloy, and/or composite thereof. Alternatively, base plate 18 may be formed of a non-metallic material, such as a plastic material, a fiberglass material, or any other non-metallic material and/or composite thereof.

In the arrangement shown, as one example, when viewed from a side 16 of system 10, base plate 18 is a generally flat of planar member, with top surface 26 extending an approximate parallel planar spaced relation to the bottom surface 28 and in approximate perpendicular relation to front end 30 and back end 31. In the arrangement shown, as one example, both first plate 38, cover 40, and second plate 42 extend from downward from bottom surface 28 of top surface 26. In the arrangement shown, as one example, when viewed from forward end 12 or rearward end 14, bottom surface 28 generally planar and extends in approximate perpendicular relation to each opposing side 16. In the arrangement shown, as one example, when viewed from forward end 12 or rearward end 14, base plate 18 includes curved portions 36 at each opposing side 16, with the curved portions 36 extending upward from top surface 26 in a generally concave manner.

Notch: In the arrangement shown, as one example, base plate 18 includes a notch 33 in its front end 30. Notch 33 is formed to be any suitable size, shape, and design and is configured to allow base plate 18 to fit with any length skateboard. Skateboards come in varying lengths meaning that the trucks 212 of skateboards are positioned at varying places. Said another way, some skateboards have trucks 212 which are positioned closer together than in other skateboards and base plate 18 must account for the closer positioned trucks 212. In order to accommodate for closer positioned trucks 212, base plate 18 includes notch 33.

In the arrangement shown, as one example, notch 33 is an open or cut-out area which extends back a distance from the front end 30 of base plate 18. In the arrangement shown, as one example, notch 33 starts near one side 32 of base plate 18 and extends to near the opposing side 32 of base plate 18, more specifically, in the arrangement shown, as one example, near each side 32 of base plate 18, notch 33 generally begins at or near where top surface 26 of base plate 18 meets curved portion 36 of base plate 18. Without notch 33, base plate 18 may not be suitable for use any skateboards with closely positioned trucks 212 because base plate 18 could overlap with trucks 212. If base plate 18 were to overlap with trucks 212, base plate 18, and therefore system 10, could not be tightly and securely attached to skateboard 200. However, with notch 33, closely positioned trucks 212 on shorter skateboards 200 may fit within notch 33, thereby still allowing base plate 18, and system 10, to be tightly and securely attached to skateboard 200, even though the overall distance from front end 30 to back end 31 of base plate 18 may be longer than the distance between trucks 212 of skateboard 200.

Compressible Members: In the arrangement shown, as one example, base plate 18 includes compressible members 34. Compressible members 34 are formed of any suitable size, shape, and design and are configured to provide a secure engagement between base plate 18 and the bottom surface 218 of deck 210 of skateboard 200. In the arrangement shown, as one example, compressible members 34 are formed of a non-metallic material which is able to be compressed or squished when placed in-between two separate members being forced together. In the arrangement shown, as one example, compressible members 34 are formed of a non-metallic material which also has a high coefficient of friction in order to ensure base plate 18 is held securely in place when connected to base plate 18 and bottom surface 218 of deck 210 of skateboard 200. As one example, compressible members 34 are a rubber material in order to be compressed when base plate 18 is secured to deck 210 and also provide a surface with a high coefficient of friction which ensures system 10 does not shift or more around which skateboard 200 when a user is riding skateboard 200.

Curved Portion: In the arrangement shown, as one example, compressible members 34 are used to form the curved portion 36 of base plate 18. Skateboards may have decks 210 which may be curved, however the curvature of different skateboards 200 can vary and system is configured to connect to multiple different skateboards, therefore in one or more arrangements system 10 is configured to account for varying curvatures in different decks 210. In order to accommodate this curvature, in the arrangement shown as one example base plate 18 includes curved portions 36. Curved portions 36 are formed of any suitable size, shape, and design and are configured to ensure a proper, tight fit against the bottom surface 218 of deck 210 of a skateboard 200. In order to accommodate all possible shapes, curvatures, and configurations of a deck 210, in the arrangement shown as one example, the curved portions 36 are formed of compressible members 34. That is, in order to facilitate for all different shapes, styles, and degrees of curvature of deck 210, the curved portions 36 are formed of compressible members 34 so that the curved portions 36 can compress to conform to the curvature of the bottom surface 218 of deck 210.

First Plate: In the arrangement shown, as one example, base plate 18 includes a set of first plates 38. First plates 38 are formed of any size, shape, and design and are configured to facilitate alignment of axle 112 of wheel 108. In the arrangement shown, as one example, first plates 38 are generally flat and planar member which extend downward a distance from the bottom surface 28 of base plate 18. In the arrangement shown, as one example, when viewed from a side 16, first plates 38 extend downward and taper inward as they extend further downward until they stop at their bottom edges. In the arrangement shown, as one example, there is one first plate 38 near each side 16 of system 10, that is there is one a first plate 38 near the left side 16 of system 10 and a first plate 38 near the right side 16 of system 10.

First plates 38 may be pieces which are connected to base plate 18 through a process such as welding, adhesion, screwing, bolting, or the like, or first plates 38 may be included in base plate 18 when base plate 18 is manufactured. If manufactured separately and then connected to base plate 18, first plates 38 are single, unitary members that are formed in a manufacturing process such as machining, casting, additive manufacturing, or the like to form a unitary and monolithic member. In the arrangement shown, as one example, first plates 38 may be formed primarily of a metallic material such as steel, aluminum, chromium, or any other metallic material, alloy, and/or composite thereof. Alternatively, first plates 38 may be formed of a non-metallic material, such as a plastic material, a fiberglass material, or any other non-metallic material and/or composite thereof.

In the arrangement shown, as one example, each first plate 38 includes a recess 46. Recess 46 is formed to be any suitable size, shape, and design and is facilitate the passing of axle 112 of wheel 108 through first plate 38. In the arrangement shown, as one example, recess 46 is generally ovular in shape, extending upward from the bottom edge of first plate 38 a distance and ending in a generally semi-circular manner. In the arrangement shown, as one example, recess 46 is generally shaped to receive a cylindrical shaft therein, however recess 46 may be formed of any suitable size, shape, and design necessary for the type of shaft therein, therefore recess 46 may be formed of a generally square, rectangular, triangular, or any other shape opening. In the arrangement shown, as one example, recess 46 extends upward from the bottom edge of first plate 38 a distance such that the opening 54 of cover 40 is aligned with at least a portion of recess 46.

Cover 40 is formed of any suitable size, shape, and design and is configured to at least partially surround first plate 38 and facilitate the secured engagement of axle 112 of wheel 108 to base plate 18. Cover 40 is a piece which is manufactured separately from base plate 18 and is attached to first plate 38 via fasteners such as screws or bolts, thereby becoming a part of base plate 18. In the arrangement shown, as one example, cover 40 is formed of a non-metallic material, such as a plastic material, a fiberglass material, or any other non-metallic material or composite thereof. Alternatively, cover 40 may be formed of any metallic material. In the arrangement shown, as one example, cover 40 is formed of a single, unitary member that is formed in a manufacturing process such as extrusion, molding, additive manufacturing, or the like.

In the arrangement shown, as one example, cover 40 is shaped similar to first plate 38. In the arrangement shown, as one example, cover 40 extends downward from bottom surface 28 of base plate 18 and, when viewed from a side 16, cover 40 includes sides 48 which generally extends straight downward from bottom surface 28 before angling and tapering inward until it meets at a rounded bottom point 50. In the arrangement shown, as one example, sides 48 extend past the back side 52 of cover 40. In this way, the sides 48 extend around first plate 38 in order to at least partially surround first plate 38.

In the arrangement shown, as one example, cover 40 includes an opening 54. Opening 54 is formed of any suitable size, shape, and design and is configured to facilitate the passing of axle 112 of wheel 108 through cover 40. In the arrangement shown, as one example, opening 54 is generally circular and extends through cover 40 from its front side 53 to its back side 52. In the arrangement shown, as one example, opening 54 is generally shaped to receive a cylindrical shaft therein, however opening 54 may be formed of any suitable size, shape, and design necessary for the type of shaft therein, therefore opening 54 may be formed of a generally square, rectangular, triangular, or any other shape opening. In the arrangement shown, as one example, opening 54 is located above the middle of the rounded bottom point 50 of cover 40 and is located above the rounded bottom point 50 a distance such that when cover 40 is connected to first plate 38, opening 54 is aligned with at least a portion of recess 46 of first plate 38. In this way, axle 112 of wheel 108 may pass through both first plate 38 and cover 40 by passing through recess 46 of first plate 38 and through opening 54 of cover 40. In the arrangement shown, as one example, opening 54 is fully contained within cover 40 such when axle 112 of wheel 108 is passed through opening 54 of cover 40, wheel assembly 22 is securely engaged with cover 40 and, by its secured engagement cover 40, wheel assembly 22 is also operably connected to base plate 18.

Second Plate: In the arrangement shown, as one example, base plate 18 includes a second plate 42. Second plate 42 is formed of any suitable size, shape, and design and is configured to facilitate secured attachment of motor 66 of drive unit 20 to base plate 18. In the arrangement shown, as one example, second plate 42 is a generally flat and planar member which extends downward a distance from the bottom surface 28 of base plate 18. In the arrangement shown, as one example, when viewed from a side 16, second plate 42 is generally rectangular in shape, with sides 56 which generally straight downward and in parallel planar spaced relation to one another, however the bottom edge 58 of second plate 42 has a slight, generally convex curvature as it extends from one side 56 to the other side 56.

Second plate 42 may be a piece which is connected to base plate 18 through a process such as welding, adhesion, screwing, bolting, or the like, or second plate 42 may be included in base plate 18 when base plate 18 is manufactured. If manufactured separately and then connected to base plate 18, second plate 42 is a single, unitary member that is formed in a manufacturing process such as machining, casting, additive manufacturing, or the like to form a unitary and monolithic member. In the arrangement shown, as one example, second plate 42 may be formed primarily of a metallic material such as steel, aluminum, chromium, or any other metallic material, alloy, and/or composite thereof. Alternatively, second plate 42 may be formed of a non-metallic material, such as a plastic material, a fiberglass material, or any other non-metallic material and/or composite thereof.

In the arrangement shown, as one example, second plate 42 includes a centrally located opening 60. Opening 60 is formed to be any suitable size, shape, and design and is configured to facilitate the passing of the drive shaft 86 of motor 66 of drive unit 20 through second plate 42, thereby facilitating secured attachment of motor 66 of drive unit 20 to second plate 42. In the arrangement shown, as one example, opening 60 is generally in the geometric shape of an obround, having a top and bottom edge which extends generally straight and in parallel planar spaced relation to one another, and having ends which are generally semi-circular in shape. In the arrangement shown, as one example, opening 60 is sized and shaped to receive a generally circular drive shaft 86 of motor 66, however opening 60 is not so limited and may be sized, shaped, and designed to receive any other shape of drive shaft, therefore opening 60 may be generally square, rectangular, circular, triangular, or any other shape. In the arrangement shown, as one example, opening 60 is located centrally on second plate 42 and extends through second plate 42 from a front side to a back side of second plate 42.

In the arrangement shown, as one example, when drive shaft 86 of motor 66 is passed through opening 60 of second plate 42, drive shaft 86 is vertically contained in opening 60 and motor 66 is on the inside of second plate 42. Once drive shaft 86 is passed through opening 60, motor pulley 70 is placed onto drive shaft 86 on the outer side of second plate 42. With motor pulley 70 on the outer side of second plate 42 and motor 66 on the inner side of second plate 42, drive shaft 86 is vertically and horizontally securely held within opening 60. In this way, opening facilitates the passing of the drive shaft 86 of motor 66 of drive unit 20 through second plate 42 and, thereby, the secured attachment of motor 66 of drive unit 20 to second plate 42.

While base plate 18 has been primarily described with reference to one or more arrangements shown, as one example, it will be understood by those skilled in the art that any other configuration of base plate 18 may be used in order to facilitate engagement with the skateboard 200 and with drive unit 20.

Drive Unit:

In the arrangement shown, as one example, system 10 includes drive unit 20. Drive unit 20 is formed of any suitable size, shape, and design and is configured to power skateboard 200. More specifically, in the arrangement shown, as one example, drive unit 20 is configured to operably connect to wheel assembly 22 and provide power to wheel assembly 22 which facilitates the movement of skateboard 200. In the arrangement shown, as one example, drive unit 20 includes a battery 62, a battery housing 64, a motor 66 with a control assembly 68, a motor pulley 70, and a belt 72, among other components as described herein.

Battery: In the arrangement shown, as one example, drive unit 20 includes control battery 62. Battery 62 is formed of any suitable size, shape, and design and is configured to provide the energy to operate motor 66, which in turn facilitates the rotation of wheel assembly 22. Battery 62 may be any type of battery or energy source, so long as it may be used in system in order to provide energy to operate motor 66.

Battery Housing: In the arrangement shown, as one example, battery 62 is contained within battery housing 64. Battery housing 64 is formed of any suitable size, shape, and design and is configured to attach to base plate 18 and hold battery 62 therein. In the arrangement shown, as one example, battery housing includes end walls 74, side walls 76, a bottom wall 78, and arms 82.

In the arrangement shown as one example, battery housing 64 is formed of a single, unitary member that is formed in a manufacturing process such as molding, machining, additive manufacturing, or the like to form a unitary and monolithic member. Alternatively, battery housing 64 may be formed of multiple pieces that are connected or assembled to one another through adhesion, screwing, or the like. In the arrangement shown, as one example, battery housing 64 is formed primarily of a non-metallic material such as a hard plastic material, however any other type of non-metallic material may be used to form battery housing 64. Alternatively, battery housing 64 may be formed of a metallic material such as steel, aluminum, chromium, or any other metallic material, alloy, and/or composite thereof.

In the arrangement shown, as one example, battery housing 64 has end walls 74 at its front and back ends which extend vertically and in approximate parallel planar spaced relation to one another. In the arrangement shown, as one example, battery housing 64 includes side walls 76 which extend a distance vertically and in approximate parallel planar spaced relation to one another and in approximate perpendicular planar relation to end walls 74. In the arrangement shown, as one example, battery housing 64 includes a bottom wall 78 which connects to each of the end walls 74 and side walls 76 at their lowest edge and provides a bottom surface upon which battery 62 rests when contained within battery housing 64. In the arrangement shown, bottom wall 78 is a generally rectangular planar member which extends longitudinally between each end wall 74 and laterally between each side wall 76. With bottom wall 78 meeting each of the end walls 74 and side walls 76 at their lowest edges, a hollow center 80 is formed within battery housing 64. This hollow center 80 provides the space within which battery 62 is contained.

In the arrangement shown, as one example, battery housing 64 includes arms 82. Arms 82 are configured to connect battery housing 64 to base plate 18. In the arrangement shown, as one example, two arms 82 extend upward a distance from each side wall 76, with one arm 82 positioned near the front end wall 74 and one arm 82 positioned near the back end wall 74. At the end of arm 82, is a protrusion 84 which is configured to facilitate connection of battery housing 64 to base plate 18. In the arrangement shown, as one example, protrusion 84 extends outward from the top of each arm 82 and is configured to engage with base plate 18. With protrusion 84 engaged with base plate 18, battery housing 64 is essentially hung from base plate 18 in a secure manner. With battery housing 64 securely hung from base plate 18, battery housing 64 and battery 62 are operably connected to base plate 18.

Motor: In the arrangement shown, as one example, drive unit 20 includes motor 66. Motor 66 is formed of any suitable size, shape, and design and is configured to provide power to wheel assembly 22 in order to facilitate powered movement of skateboard 200. Motor 66 may be any device that converts electrical energy to movement, or more specifically to rotational energy. In the arrangement shown, as one example, motor 66 includes control assembly 68 and a drive shaft 86.

Control Assembly: In the arrangement shown, as one example, drive unit 20 includes control assembly 68. Control assembly 68 is formed of any suitable size, shape, and design and is configured to control the operation of motor 66 and the speed at which skateboard 200 is traveling. In the arrangement shown, as one example, control assembly 68 includes at least one microprocessor 90, a memory 92, instructions 94, an antenna 96, and a receiver and/or transceiver 98. In the arrangement shown, as an example, the control assembly 68 is attached to the base plate 18. In other arrangements, the control assembly may be integrally attached to the motor 66.

In the arrangement shown, as one example, control assembly 68 is electrically connected, either through wired connections or wirelessly, to battery 62 and motor 66. In the arrangement shown, as one example, control assembly 68 receives inputs from a user utilizing a remote controller 88 in the user's possession. Control assembly 68 receives these inputs and the microprocessor 90 processes these inputs and outputs commands according to instructions 94 stored in memory 92. Memory 92 may be included as part of microprocessor 90 or operably connected to microprocessor 90. Receiver and/or transceiver 98 is connected to microprocessor 90. A receiver is used if one way communication is utilized, whereas a transceiver is used if two-way communication is utilized. Receiver/transceiver 98 is connected with an antenna 96, such as a monopole antenna, a loop antenna, a fractal antenna, or any other form of an antenna. Antenna 96 receives wireless signals from remote controller 88, transmits these signals to receiver/transceiver 98 which processes these signals and then transmits these processed signals to microprocessor 90, which processes these signals according to instructions 94 stored in memory 92. In this arrangement, remote controller 88 is any form of a remote control device that transmits wireless signals through the air such as a conventional remote control, a cell phone, a wireless device, an internet connected device, a hard-wired device, or any other device capable of transmitting remote control signals.

Drive Shaft, Motor Pulley, and Belt: In the arrangement shown, as one example, motor 66 includes drive shaft 86. Drive shaft 86 is formed of any suitable size, shape, and design and is configured to connect to motor 66 and extend outward from motor 66 in order to transmit the rotational movement of motor 66 to motor pulley 70. In the arrangement shown, as one example, drive shaft 86 is a generally cylindrical rod which extends outward from the side of motor 66 and connects to its end to motor pulley 70.

In the arrangement shown, as one example, drive unit 20 includes motor pulley 70. Motor pulley 70 is formed of any suitable size, shape, and design and is configured to facilitate the transfer of rotational movement from motor 66 to wheel assembly 22. In the arrangement shown, as one example, motor pulley 70 is a generally circular member with a middle section 100 and side walls 102 on each side of the middle section 100. In the arrangement shown, motor pulley 70 includes an opening 104 which extends through motor pulley 70 from one side wall 102 to the other side wall 102. Opening 104 is formed to be any suitable size, shape, and design and is configured to receive drive shaft 86 of motor 66 therein. In this way, drive shaft 86 of motor 66 extends through opening 104, thereby connecting motor pulley 70 to motor 66.

In the arrangement shown, as one example, side walls 102 have a bigger diameter than middle section 100 such that side walls 102 extend past the outer part of middle section 100. This configuration is important because belt 72 is configured to extend around motor pulley 70 such that is rests between side walls 102 which connecting to middle section 100. Belt 72 may be any type of belt which forms a loop and can be used to rotate around both motor pulley 70 and wheel pulley 106 of wheel assembly 22. In the arrangement shown, as one example, middle section 100 of motor pulley 70 optionally includes teeth 105 which engage belt 72, although in other embodiments, the belt and the motor pulley are both flat and use friction to impart the forces necessary for powered movement. In this way, when motor 66 is operated, drive shaft 86 causes motor pulley 70 to rotate and the teeth 105 of motor pulley 70 catch and engage belt 72. When belt 72 is engaged with the teeth 105 of motor pulley 70, belt 72 is caused to rotate around with motor pulley 70. When belt 72 is rotated around motor pulley 70, belt 72 causes wheel pulley 106 of wheel assembly 22 to rotate as well. In this way, drive unit 20 provides power and rotational movement to wheel assembly 22 which facilitates the powered movement of skateboard 200 through the use of drive shaft 86, motor pulley 70, and belt 72.

While drive unit 20 has been primarily described with reference to one or more arrangements shown, as one example, it will be understood by those skilled in the art that any other configuration of drive unit may be used in order to power skateboard 200, and more specifically, to operably connect to wheel assembly 22 and provide power to wheel assembly 22 which facilitates the movement of skateboard 200.

Wheel Assembly:

In the arrangement shown, as one example, system 10 includes wheel assembly 22. Wheel assembly 22 is formed of any suitable size, shape, and design and is configured to facilitate powered movement of skateboard 200. In the arrangement shown, as one example, wheel assembly 22 includes a wheel pulley 106, wheel 108 with bearings 110, and an axle 112.

Wheel Pulley: In the arrangement shown, as one example, wheel assembly 22 includes a wheel pulley 106. Wheel pulley 106 is formed of any suitable size, shape, and design and is configured to transfer powered movement from motor pulley 70 to wheel 108. In the arrangement shown, as one example, belt 72 extends around wheel pulley 106, thereby facilitating connection with motor 66. In the arrangement shown, as one example, wheel pulley 106 includes an outer side wall 114, an inner side wall 116, and teeth 118.

In the arrangement shown, as one example, wheel pulley 106 is a generally circular member which has an open center 120. In the arrangement shown, as one example, wheel pulley 106 is a generally thin member due to open center 120 and optionally includes teeth 118 on its outer surface, although in other embodiments the belt 72 and the wheel pulley interface may be flat and simply use friction to impart the force necessary for powered movement. In the arrangement shown, as one example, teeth 118 extend outward from wheel pulley 106 and are configured to engage belt 72, such that when belt 72 rotates along with motor pulley 70, belt 72 engages teeth 118 and causes wheel pulley 106 to rotate as well. Outer side wall 114 of wheel pulley 106 is a generally flat and planar surface which has a thickness equal to the thickness of wheel pulley 106. Inner side wall 116 is a generally flat and planar member which extends a distance outward from wheel pulley 106 and has a thickness which is greater than the thickness of wheel pulley 106. Said another way, inner side wall 116 is sized such that it extends a distance farther out from the center of wheel pulley 106 than the outermost part of the teeth 118 of wheel pulley 106.

In the arrangement shown, as one example, inner side wall 116 is connected directly to the side wall 122 of wheel 108. In the arrangement shown, as one example, inner side wall 116 is connected to side wall 122 of wheel 108 through fasteners such as bolts or screws, however inner side wall 116 may be connected to side wall 122 of wheel 108 through any other means such that inner side wall 116 is securely attached to side wall 122 of wheel 108.

Wheel: In the arrangement shown, as one example, wheel assembly 22 includes a wheel 108. Wheel 108 is formed of any suitable size, shape, and design and is configured to operably connect to motor 66 and rotate in order to facilitate the powered movement of skateboard 200. In the arrangement shown, as one example, wheel 108 is a single wheel that is centrally located between the opposing left and right sides 208 of skateboard 200. In the arrangement shown, as one example, wheel 108 includes bearings 110 and an axle 112.

In the arrangement shown, as one example, wheel 108 is formed of a non-metallic material, such as polyurethane which is commonly used to make skateboard wheels, however any other non-metallic material, or even metallic materials may be used in order to form wheel 108. In the arrangement shown, as one example, wheel 108 is formed by a manufacturing process such as molding, however other processes such as machining, additive manufacturing, or the like may be used to form wheel 108.

In the arrangement shown, as one example, when system 10 is connected to a skateboard 200, wheel 108 is centrally located between the opposing left and right sides 208 and located behind the front truck 212 of skateboard 200. In the arrangement shown, as one example, wheel 108 has a diameter which is large enough that, when system 10 is connected to a skateboard, the wheels 214 connected to the front truck 212 of skateboard 200 are lifted off the ground. In this way, only the wheels 214 connected to the rear truck 212 of skateboard 200 and wheel 108 of wheel assembly 22 are resting on the ground. When the motor 66 of system 10 is operated, it causes the rotation of wheel 108, which causes skateboard 200 to move forward. As skateboard 200 moves, wheel 108 continues to stay in contact with the ground, as do the wheels 214 connected to the rear truck 212 of skateboard 200, however the wheels 214 connected to the front truck 212 of skateboard 200 still do not contact the ground in forward motion or when minor turns are made.

In the arrangement shown, as one example, wheel 108 is generally circular in shape. When viewed from forward end 12 of system 10, as one example, wheel 108 extends between side walls 122 and has a slight convex curvature as it extends from one side wall 122 to the other side wall 122. Said another way, wheel 108 has a slight curvature such that the middle of wheel 108 has a greater diameter than the diameter at or near the side walls 122. This curvature is important to wheel 108 because this curvature allows the user to turn the skateboard when utilizing system 10. If wheel 108 did not have this curvature, the wheel would not be able to effectively or easily turn, it could essentially only go in a straight line. However, with this curvature of wheel 108, a user is able to lean to one side 208 of the board, as they would a normal skateboard, and the skateboard 200 utilizing system 10 will turn. As described above, the wheels 214, which are attached to the front truck 212 of skateboard 200 will generally not touch the ground when moving in a straight line or making slight turns. However, when a user makes a sharp turn on a skateboard 200 which has system 10 attached to it, the curvature of wheel 108 will cause the front end 206 of skateboard 200 to slope, which may cause a wheel 214 connected to the front truck 212 to touch the ground. This is advantageous to have one of the wheels 214 connected to the front truck 212 of skateboard 200 to touch the ground when a sharp turn is being made while utilizing system 10 because this extra contact with the ground helps provide for extra stabilization of the board during the turn. In this way, the curvature of wheel 108 is important and advantageous for use in system 10.

In the arrangement shown, as one example, the side walls 122 of wheel 108 are connected to the inner side wall 116 of wheel pulley 106 as described above. When wheel 108 is attached to wheel pulley 106, wheel 108 is configured to rotate along with wheel pulley 106 about its center axis. In the arrangement shown, as one example, wheel 108 includes bearings 110. Bearings 110 are formed of any suitable size, shape, and design and are configured to allow wheel 108 to rotate about axle 112 while axle 112 is stationary. In the arrangement shown, as one example, bearing 110 may be a ball bearing, a roller bearing, a linear bearing, a bush bearing, or any other kind of bearing, so long as wheel 108 is able to rotate while axle 112 is stationary.

In the arrangement shown, as one example, wheel 108 includes an axle 112. Axle 112 is formed of any suitable size, shape, and design and is configured to form the axis about which wheel 108 rotates, as well as facilitate connection of wheel assembly 22 to base plate 18. In the arrangement shown, as one example, axle 112 is a generally circular rod which extends through wheel 108 along its center axis. When wheel 108 rotates, its axis of rotation is colinear with the center axis of axle 112, however, axle 112 does not rotate with wheel 108 because wheel 108 includes bearings 110. However, axle 112 is not so limited and any other shape, size, or design may be used as axle 112.

In the arrangement shown, as one example, axle 112 is also configured to facilitate connection of wheel assembly 22 to base plate 18. As described herein, axle 112 is configured to be held within recess 46 of first plate 38 and within opening 54 of cover 40, thereby securing axle 112 and wheel 108 to base plate 18. In the arrangement shown, as one example, axle 112 is extended through the opening 54 of cover 40 and recess 46 of first plate 38 near one side 16 of system 10. Axle 112 is then extended through wheel 108 and bearings 110 and wheel 108 is positioned along axle 112 such that it is centrally positioned between opposing left and right sides 208 of skateboard 200. Axle 112 is then further extended through the recess 46 of the other first plate 38 and through opening 54 of the other cover 40 near the opposing side 16 of system 10. Once axle 112 is placed through the openings 54 of covers 40 and the recesses 46 of the first plates 38, wheel assembly 22 is securely engaged with and connected to base plate 18.

While wheel assembly 22 has been primarily described with reference to one or more arrangements shown, as one example, it will be understood by those skilled in the art that any other configurations of wheel assembly 22 may be used in order to facilitate powered movement of skateboard 200.

Once wheel assembly 22 is operably connected to drive unit 20 and base plate 18, system 10 is ready to connect to skateboard 200.

Straps:

In the arrangement shown, as one example, system 10 includes straps 24. Straps 24 are formed of any suitable size, shape, and design and are configured to securely connect system to skateboard 200. In the arrangement shown, as one example, straps 24 are nylon straps which connect via buckles 124. However, straps 24 may be formed of any other material, such as polyester, plastic, polypropylene, or any other material which is adjustable, pliable, and durable and can be used to attach system 10 to skateboard 200. In the arrangement shown, as one example, straps 24 include buckles 124 at or near each end of straps 24 and may be adjustable such that skateboards of differing sizes may be accommodated. Buckles 124 are formed of any suitable size, shape, and design and are configured to securely attach the two ends of straps 24. In multiple arrangements, buckles 124 may be a side release buckle, a cam buckle, or any other buckle or mechanism which can be used to securely connect the two ends of straps 24. In another arrangement, straps 24 may be elastic straps that are able to be stretched over the deck 210 and trucks 212 of the skateboard 200.

In the arrangement shown, as one example, straps 24 extend around base plate 18 of system 10, thereby effectively attaching to system 10. In the arrangement shown, as one example, there are truck straps 128 and deck straps 130. Truck straps 128 are configured to connect system 10 so trucks 212 of skateboard 200, thereby securing system 10 in a longitudinal direction. Said another way, truck straps 128 wrap around front truck 212 and rear truck 212 of skateboard 200 such that system 10 is held securely and will not shift forward or rearward while system 10 is connected to skateboard 200.

Similarly, in the arrangement shown, as one example, deck straps 130 are configured to connect system 10 to deck 210 of skateboard 200, thereby securing system 10 in a lateral direction. Said another way, deck straps 130 wrap tightly around deck 210 of skateboard 200 such that system 10 is held securely and will not shift left or right while system 10 is connected to skateboard 200. With truck straps 128 and deck straps 130 wrapped around the trucks 212 and deck 210 of skateboard 200, respectively, system 10 is securely and tightly connected to skateboard 200 and will not move side-to-side or forward and backward while in use.

While straps 24 have been primarily described with reference to one or more of the arrangements shown, as one example, it will be understood by those skilled in the art that any other configuration of straps 24 may be used in order to facilitate connection of system 10 to skateboard 200.

In Operation:

System 10 may be operated by a user to travel distances easily and effortlessly on a skateboard 200. First, a user provides a skateboard 200, which will generally have a deck 210, a pair of trucks 212 connected to the deck 210, and a pair of wheels 214 connected to each of the trucks 212. In this way, there is a front truck 212 with a pair of front wheels 214 and a rear truck 212 with a pair of rear wheels 214. The user can then attach system 10 to the skateboard 200.

In order to do so, the user will take straps 24 and wrap them around skateboard 200 to secure system 10 to skateboard 200. Specifically, the user will take a truck strap 128, which is connected to system 10, and wrap it tightly around front truck 212, Once truck strap 128 is wrapped appropriately around the front truck 212, the user will use buckles 124 to secure the ends of truck strap 128 together, thereby securing system 10 to front truck 212. The user will then take a second truck strap 128, which is connected to system 10, and wrap it tightly around the rear truck 212. Once truck strap 128 is wrapped appropriately around the rear truck 212, the user will use buckles 124 to secure the ends of truck strap 128 together, thereby securing system to rear truck 212. With truck straps 128 around both the front truck 212 and the rear truck 212, system 10 is attached to skateboard 200 such that system 10 will not move forward or backward while in use.

Next the user will take a first deck strap 130, which is connected to system 10, and wrap it tightly around deck 210 of skateboard 200. Once deck strap 130 is wrapped appropriately around the deck 210, the user will use buckles 124 to secure the ends of deck strap 130 together, thereby securing system 10 to deck 210. The user will repeat this process with additional deck straps 130 as needed. When completed, the user will have attached system 10 to deck 210 such that system 10 will not shift or slide side to side while in use. Importantly, deck straps 130 are generally located such that they will not get in the way of the user utilizing deck 210 for its intended purpose. That is, deck straps 130 can be placed such that they will not interfere with the feet placement of the user riding skateboard 200. In this way, system 10 provides attachment of a powered system to a skateboard without inhibiting the user's ability to actually use the skateboard 200, and more specifically the deck 210, as intended.

With the truck straps 128 and deck straps 130 wrapped securely around skateboard 200, system 10 is ready to be used to travel a distance. In the arrangement shown, as one example, with system 10 connected to skateboard 200, the set of rear wheels 214 are resting on the ground, as is wheel 108 of system 10, but the front wheels 214 of skateboard 200 are lifted off the ground due to the size and placement of wheel 108. Specifically, wheel 108 is located a behind front truck 212 and centrally positioned between the opposing left and right sides 208 of skateboard 200. In this position, wheel 108 is close enough to the set of front wheels 214 and wheel 108 has a large enough diameter that wheel 108 causes front wheels 214 to be lifted off the ground.

In order to move the drive unit, the user will utilize the remote controller 88 to send commands to control assembly 68 as described herein. Once control assembly 68 receives the command from remote controller 88 to move forward, the control assembly will cause battery 62 to provide electrical energy to motor 66. With electrical energy provided to motor 66, motor 66 will begin to rotate, which will in turn rotate drive shaft 86. Drive shaft 86 is connected to motor pulley 70 and when drive shaft 86 rotates, this will cause motor pulley 70 to rotate. As motor pulley 70 rotates, the teeth 105 of motor pulley 70 engage belt 72, which extends around motor pulley 70 at one side, to rotate with motor pulley 70. At its other end, belt 72 extends around wheel pulley 106. As belt 72 rotates around motor pulley 70, the teeth 118 of wheel pulley 106 engage belt 72 and cause wheel pulley 106 to rotate as well. In the arrangement shown, as one example, motor pulley 70 is half the side of wheel pulley 106, meaning that each time motor pulley 70 completes a rotation, wheel pulley 106 has completed half a rotation, so motor pulley 70 rotates twice as fast as wheel pulley 106.

In the arrangement shown, as one example, wheel pulley 106, or more specifically the inner side wall 116 of wheel pulley 106 is connected to the side wall 122 of wheel 108. Due to this connection, as wheel pulley 106 is caused to rotate by belt 72, wheel 108 is also caused to rotate by wheel pulley 106. As wheel 108 rotates, the skateboard 200 is propelled forward. The user can use remote controller 88 to speed up or slow down the rate of travel of skateboard 200. Because of the curvature of wheel 108, the user can travel in a straight direction and can also cause skateboard 200 to turn. During slight turns, the front wheels 214 of skateboard 200 will continue to stay off the ground, however if a sharp turn is made by the user, the front wheels 214 of skateboard 200 will make contact with the ground and provide additional support and stability during the turn.

Once the user reached their destination, the user can leave system 10 on the skateboard 200, or the user can remove system 10 from skateboard 200. The user can remove system 10 from the skateboard by unhooking buckles 124 on each of the truck straps 128 and each of the deck straps 130. The user will then unwrap the deck straps 130 from around deck 210 and, likewise, unwrap the truck straps 128 from both the front truck 212 and the rear truck 212. The user may desire to remove system 10 from skateboard 200 if the user has used system 10 to travel to a skate park and wants to skate freely and perform tricks using skateboard 200. In this way, system 10 can be used to travel distances, which still allowing the user to utilize skateboard 200 for more recreational or sporting use.

Alternative Arrangement

An alternative arrangement of a power system 300 for a skateboard 200 is presented herein. Except as expressly noted below, elements of the alternative arrangement are designed and function similarly to and are interchangeable with previous arrangements. In the alternative arrangement shown, as one example, a skateboard 200 may be any skateboard, such as, by way of example and not limitation, street skateboards, mini skateboards, longboards, and any other type of skateboard. In the arrangement shown, as one example, skateboard 200 has a top side 202, a bottom side 204, opposing front and back ends 206 (or simply “ends 206”), and opposing left and right sides 208 (or simply “sides 208”). In the arrangement shown, as one example, skateboard 200 is a street skateboard having a deck 210, trucks 212, and wheels 214, among other components as described herein. While this alternative arrangement of skateboard 200 has been described according to the alternative arrangement shown, as one example, any other combination or arrangement may be used and is hereby contemplated for use.

Deck: In the arrangement shown, as one example, skateboard 200 includes deck 210. Deck 210 is formed of any suitable size, shape, and design and are configured to provide a surface upon which a rider stands when riding skateboard 200. In the arrangement shown, as one example, deck 210 has a top surface 216, a bottom surface 218, opposing front and back ends 220 (or simply “ends 220”), and opposing left and right sides 222 (or simply “sides 222”).

In the arrangement shown as one example, deck 210 may be formed of a single, unitary member that is formed in a manufacturing process such as machining or the like to form a unitary and monolithic member. Deck 210 may be formed of any number of non-metallic materials such as a wooden material, fiberglass, plastic, a composite material, or any other non-metallic material that is customary for use on skateboards.

In the arrangement shown, as one example, when viewed from top side 202, deck 210 is generally in the geometric shape of an obround, however deck 210 may be formed of any other shape or configuration, including a rectangle, an oval, or any other shape. In the arrangement shown, as one example, the front and back ends 220 of deck 210 each form a generally semi-circular end 220 and sides 222 extending from front end 220 to back end 220 in approximate parallel planar spaced relation to each side 222. In the arrangement shown, as one example, when viewed from a left or right side 208, deck 210 is curved up at each end 220 and extends between each end 220 with a generally convex curvature, such that the top surface 216 of deck 210 is higher in the middle than it is near ends 220.

In the arrangement shown, as one example, deck 210 includes holes 224. Holes 224 are formed of any suitable size, shape, and design and are configured to facilitate connection of trucks 212 to deck 210. In the arrangement shown, as one example, holes 224 extend from the top surface 216 of deck 210 through to bottom surface 218 of deck 210. In the arrangement shown, as one example, holes 224 are generally circular in shape, however holes 224 may be formed of any other shape or configuration, including an ovular shape, a square shape, a triangular shape, or any other shape. In the arrangement shown, as one example, holes 224 are configured to receive fasteners 232 of trucks 212. Holes 224 may be countersunk from the top surface 216 such that the top of each head of fasteners 232 remains below the top surface 216 of the deck 210.

While deck 210 has been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that any other configuration of deck 210 may be used in order to provide a surface upon which a rider stands when riding skateboard 200.

Truck: In the arrangement shown, as one example, skateboard 200 includes trucks 212. Trucks 212 are formed of any suitable size, shape, and design and are configured to connect deck 210 to wheels 214. In the arrangement shown, as one example, skateboard 200 includes a pair of trucks 212, however any other number of trucks may be used depending on the number of wheels 214 necessary for the particular skateboard 200. In the arrangement shown, as one example, trucks 212 include a base plate 226, a hanger 228, and an axle 230.

In the arrangement shown, as one example, truck 212 includes a base plate 226. Base plate 226 is formed of any suitable size, shape, and design and is configured to connect to trucks 212 to bottom surface 218 of deck 210. In the arrangement shown, as one example, base plate 226 is formed of a single, unitary member that is formed in a manufacturing process such as machining, casting, molding, extruding, or the like to form a unitary and monolithic member. Trucks 212 may be formed of any number of metallic materials and any composite thereof or, alternatively, trucks 212 may be formed of any number of non-metallic materials such as a wooden material, fiberglass, plastic, or any other non-metallic materials or composites thereof.

In the arrangement shown, as one example, base plate 226 is shaped in order to conform to bottom surface 218 of deck 210 in order to tightly and closely engage with bottom surface 218 of deck 210. In the arrangement shown, as one example, bottom surface 218 includes openings (not shown) which receive fasteners 232 of trucks 212, which also extend through holes 224 of deck 210. When fasteners 232 of trucks 212 are extending through the openings (not shown) of trucks 212 and through holes 224 of deck 210, base plate 226 is operably connected to deck 210.

In the arrangement shown, as one example, base plate 226 includes a pin (not shown). The pin of base plate 226 is formed of any suitable size, shape, and design and is configured to rotatably connect hanger 228 to base plate 226. In the arrangement shown, as one example, the pin of base plate 226 is a generally cylindrical pin which extends downward from the bottom surface of base plate 226. In the arrangement shown, as one example, at the lowest end of the pin, there is a threaded portion which is configured to receive at least one nut (not shown). In the arrangement shown, as one example, the hanger 228 is operably connected to the pin of base plate 226 by placing a first nut onto the threaded portion of the pin, the placing the pin through an opening in the hanger 228, then placing a second nut onto the threaded portion of the pin, thereby securely connecting hanger 228 to the pin of base plate 226. In this way, the pin of base plate 226 connects hanger 228 to base plate 226.

In the arrangement shown, as one example, trucks 212 include hanger 228. Hanger 228 is formed of any suitable size, shape, and design and is configured to connect to base plate 226 and to axle 230. In the arrangement shown, as one example, hanger 228 is a generally elongated member which extends from a first side to a second side. In the arrangement shown, as one example, when viewed from a front or back end 206 of skateboard 200, hanger 228 may be generally triangular in shape, with the elongated section 234 of hanger 228 extending from near one opposing side 208 to near the other opposing side 208 and extending upward to a generally narrower portion which connects to the pin of base plate 226. In the arrangement shown, as one example, the narrower portion of hanger 228 near base plate 226 includes an opening which receives the pin of base plate 226 and secured to the pin using the nuts of base plate 226 as described herein.

In the arrangement shown, as one example, the elongated section 234 of hanger 228, which extends from near one opposing side 208 to near the other opposing side 208 includes a hollow center (not shown) extending all the way through the elongated section 234. The hollow center of the elongated section 234 is formed of any suitable size, shape, and design and is configured to receive axle 230 within the hollow center. In this way, axle 230 extends complete through hanger 228, thereby facilitating connection with both axle 230 and base plate 226.

In the arrangement shown, as one example, trucks 212 include axle 230. Axle 230 is formed of any suitable size, shape, and design and is configured to facilitate connection of wheels 214 to trucks 212. In the arrangement shown, as one example, axle 230 is a generally elongated and cylindrical member. In the arrangement shown, as one example, axle 230 extends from near one opposing side 208 of skateboard 200 to near the other opposing side 208 of skateboard 200. In the arrangement shown, as one example, axle 230 extends a distance slightly longer than the elongated section 234 of hanger 228. In this way, at least a portion of each side of axle 230 extends outward from the elongated section 234 when extended through the hollow center of the elongated section 234 of hanger 228 such that at least one wheel 214 can fit over axle 230 on each opposing side 208 of skateboard 200. In the arrangement shown, as one example, axle 230 includes at least one nut on each side of axle 230 and this nut is configured to securely connect wheels 214 to axles 230. In this way, axle 230 facilitates the connection of wheels 214 to trucks 212.

While trucks 212 have been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that any other configuration of trucks 212 may be used in order to connect deck 210 to wheels 214.

Wheels:

In the arrangement shown, as one example, skateboard 200 includes wheels 214. Wheels 214 are formed of any suitable size, shape, and design and are configured to facilitate movement of skateboard 200. In the arrangement shown, as one example, wheels 214 may be any standard or non-standard wheels used on a skateboard, including, by way of example and not limitation, wheels made from a non-metallic material such as polyurethane. In the arrangement shown, as one example, wheels 214 may be formed in a manufacturing process such as molding or the like to form a unitary and monolithic member.

In the arrangement shown, as one example, wheels 214 include bearings 215 which are configured to facilitate rotation of wheels 214 around axles 230 of trucks 212. In this way, wheels 214 are able to rotate while axles 230 of trucks 212 remain stationary. This allows each wheel 214 of skateboard 200 to spin freely as necessary to transfer rotational movement of the wheels to linear movement of the axles to ensure proper travel of skateboard 200. In the arrangement shown, as one example, there are two wheels 214 connected to each axle 230, with one wheel 214 connected on each end of axle 230. In this arrangement, the bearings 215 of wheels 214 allow each wheel on the same axle 230 to spin independently of one another, meaning the wheels 214 may spin at different rates, which allow the skateboard 200 to turn as desired.

In the arrangement shown, as one example, there are four wheels 214, one on each end of each axle 230. That is, in the arrangement shown as one example, there are two wheels 214 per each truck 212 on skateboard 200, and with two wheels 214 near each opposing side 208 of skateboard 200, with one such wheel 214 near the front end 206 and the other wheel 214 near the back end 206 of skateboard 200.

While wheels 214 have been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that any other configuration of wheels 214 may be used in order to facilitate movement of skateboard 200.

Power System

With reference to the figures, a power system 300 for a skateboard (or simply “system 300”) is presented. System 300 is formed of any suitable size, shape, and design and is configured to operably connected to a skateboard 200 and provide power to skateboard 200. In the arrangement shown, as one example, system 300 has a forward end 312, a rearward end 314, and opposing left and right sides 316 (or simply “sides 316”). In the arrangement shown, as one example, system 300 includes a base plate 318, a drive unit 320, a wheel assembly 322, and straps 24, among other components as described herein. While system 300 has been described according to the arrangement shown, as one example, any combination or arrangement may be used and is hereby contemplated for use.

Base Plate:

In the arrangement shown, as one example, system 300 includes base plate 318. Base plate 318 is formed of any suitable size, shape, and design and is configured to facilitate engagement with the skateboard 200 and with drive unit 320. In the arrangement shown, as one example, base plate 318 has a top surface 326, a bottom surface 328, a front end 330, a back end 331, and opposing left and right sides 332 (or simply “sides 332”). In the arrangement shown, as one example, base plate 318 includes compressible members 348 and a curved portion 350.

In the arrangement shown, as one example, base plate 318 is formed of a single, unitary member that is formed in a manufacturing process such as machining, casting, extrusion, forming, additive manufacturing, or the like to form a unitary and monolithic member. Alternatively, base plate 318 may be formed of multiple pieces that are connected or assembled to one another through welding, screwing, bolting, friction fitting, or the like. In the arrangement shown, as one example, base plate 318 may be formed primarily of a metallic material such as steel, aluminum, chromium, or any other metallic material, alloy, and/or composite thereof. Alternatively, base plate 318 may be formed of a non-metallic material, such as a plastic material, a fiberglass material, or any other non-metallic material and/or composite thereof.

In the arrangement shown, as one example, when viewed from a side 316 of system 300, base plate 318 is a generally flat of planar member, with top surface 326 extending an approximate parallel planar spaced relation to the bottom surface 328 and in approximate perpendicular relation to front end 330 and back end 331. In the arrangement shown, as one example, when viewed from forward end 312 or rearward end 314, bottom surface 328 is generally planar and extends in approximate perpendicular relation to each opposing side 316. In the arrangement shown, as one example, when viewed from forward end 312 or rearward end 314, base plate 318 includes curved portions 350 at each opposing side 316, with the curved portions 350 extending upward from top surface 326 in a generally concave manner. Additionally, base plate 318 may include a notch as described in detail above to accommodate skateboards 200 of differing sizes.

Compressible Members 348:

In the arrangement shown, as one example, base plate 318 includes compressible members 348. Compressible members 348 are formed of any suitable size, shape, and design and are configured to provide a secure engagement between base plate 318 and the bottom surface 218 of deck 210 of skateboard 200. In the arrangement shown, as one example, compressible members 348 are formed of a non-metallic material which is able to be compressed or squished when placed in-between two separate members being forced together. In the arrangement shown, as one example, compressible members 348 are formed of a non-metallic material which also has a high coefficient of friction in order to ensure base plate 318 is held securely in place when connected to and bottom surface 218 of deck 210 of skateboard 200. As one example, compressible members 348 are a rubber material in order to be compressed when base plate 318 is secured to deck 210 and also provide a surface with a high coefficient of friction which ensures system 300 does not shift or more around which skateboard 200 when a user is riding skateboard 200.

Curved Portion:

In the arrangement shown, as one example, compressible members 348 are used to form the curved portion 350 of base plate 318. Skateboards may have decks 210 which may be curved, however the curvature of different skateboards 200 can vary and system 300 is configured to connect to multiple different skateboards, therefore in one or more arrangements system 300 is configured to account for varying curvatures in different decks 210. In order to accommodate this curvature, in the arrangement shown as one example base plate 318 includes curved portions 350. Curved portions 350 are formed of any suitable size, shape, and design and are configured to ensure a proper, tight fit against the bottom surface 218 of deck 210 of a skateboard 200. In order to accommodate all possible shapes, curvatures, and configurations of a deck 210, in the arrangement shown as one example, the curved portions 350 are formed of compressible members 348. That is, in order to facilitate for all different shapes, styles, and degrees of curvature of deck 210, the curved portions 350 are formed of compressible members 348 so that the curved portions 350 can compress to conform to the curvature of the bottom surface 218 of deck 210.

Drive Unit:

In the arrangement shown, as one example, system 300 includes drive unit 320. Drive unit 320 is formed of any suitable size, shape, and design and is configured to power skateboard 200. More specifically, in the arrangement shown, as one example, drive unit 320 is configured to operably connect to wheel assembly 322 and provide power to wheel assembly 322 which facilitates the powered movement of skateboard 200. In the arrangement shown, as one example, drive unit 320 includes a battery 62, a battery housing 64, a hub motor 366, a control assembly 68, and a wheel 308, among other components as described herein.

Battery: In the arrangement shown, as one example, drive unit 320 includes control battery 62. Battery 62 is formed of any suitable size, shape, and design and is configured to provide the energy to operate hub motors 366, which in turn facilitates the rotation of wheel assemblies 322. Battery 62 may be any type of battery or energy source, so long as it may be used in system 300 in order to provide energy to operate hub motors 366.

Battery Housing:

In the arrangement shown, as one example, battery 62 is contained within battery housing 64. Battery housing 64 is formed of any suitable size, shape, and design and is configured to attach to base plate 318 and hold battery 62 therein. In the arrangement shown, as one example, battery housing includes end walls 74, side walls 76, a bottom wall 78, and arms 82.

In the arrangement shown as one example, battery housing 64 is formed of a single, unitary member that is formed in a manufacturing process such as molding, machining, additive manufacturing, or the like to form a unitary and monolithic member. Alternatively, battery housing 64 may be formed of multiple pieces that are connected or assembled to one another through adhesion, screwing, or the like. In the arrangement shown, as one example, battery housing 64 is formed primarily of a non-metallic material such as a hard plastic material, however any other type of non-metallic material may be used to form battery housing 64. Alternatively, battery housing 64 may be formed of a metallic material such as steel, aluminum, chromium, or any other metallic material, alloy, and/or composite thereof.

In the arrangement shown, as one example, battery housing 64 has end walls 74 at its front and back ends which extend vertically and in approximate parallel planar spaced relation to one another. In the arrangement shown, as one example, battery housing 64 includes side walls 76 which extend a distance vertically and in approximate parallel planar spaced relation to one another and in approximate perpendicular planar relation to end walls 74. In the arrangement shown, as one example, battery housing 64 includes a bottom wall 78 which connects to each of the end walls 74 and side walls 76 at their lowest edge and provides a bottom surface upon which battery 62 rests when contained within battery housing 64. In the arrangement shown, bottom wall 78 is a generally rectangular planar member which extends longitudinally between each end wall 74 and laterally between each side wall 76. With bottom wall 78 meeting each of the end walls 74 and side walls 76 at their lowest edges, a hollow center 80 is formed within battery housing 64. This hollow center 80 provides the space within which battery 62 is contained.

In the arrangement shown, as one example, battery housing 64 includes arms 82. Arms 82 are configured to connect battery housing 64 to base plate 18. In the arrangement shown, as one example, two arms 382 extend forwardly and rearwardly a distance from each end wall 74 and generally fit within holes 302 of downstanding flanges 304 on the base plate 318. While the holes 302 and the arms 382 are shown as round, they could be any corresponding shape such as square, triangle, or any other shape to facilitate connection of battery housing 64 to base plate 318. With arms 382 engaged with holes 302 of base plate 318, battery housing 64 is essentially hung from base plate 318 in a secure manner. With battery housing 64 securely hung from base plate 318, battery housing 64 and battery 62 are operably connected to base plate 318.

Motor:

In the arrangement shown, as one example, drive unit 320 includes hub motors 366. Hub motors 366 are formed of any suitable size, shape, and design and are configured to provide power to wheel assemblies 322 in order to facilitate powered movement of skateboard 200. Hub motors 366 may be any device that converts electrical energy to movement, or more specifically to rotational movement. In the arrangement shown, two wheel assemblies 322 each include a hub motor 366 operably coupled to each wheel 308 of each wheel assembly 322.

Control Assembly:

In the arrangement shown, as one example, drive unit 320 includes control assembly 68.

In the arrangement shown, as one example, drive truck 306 includes a base plate 310, a hanger 324, and an axle 333.

In the arrangement shown, as one example, drive truck 306 includes a base plate 310. Base plate 310 is formed of any suitable size, shape, and design and is configured to connect to drive truck 306 to bottom surface 218 of deck 210. In the arrangement shown, as one example, base plate 310 is formed of a single, unitary member that is formed in a manufacturing process such as machining, casting, molding, extruding, or the like to form a unitary and monolithic member. Drive truck 306 may be formed of any number of metallic materials and any composite thereof or, alternatively, drive truck 306 may be formed of any number of non-metallic materials such as a wooden material, fiberglass, plastic, or any other non-metallic materials or composites thereof.

In the arrangement shown, as one example, base plate 310 is shaped in order to conform to bottom surface 328 of base plate 318 in order to tightly and closely engage with bottom surface 328 of base plate 318. In the arrangement shown, the base plate 310 of the drive truck is formed integrally with the base plate 318, although the base plate 310 of the drive truck may be formed separately and coupled to the base plate 318 by welding, fasteners, or any other method.

In the arrangement shown, as one example, base plate 310 includes a pin 334. The pin 334 of base plate 310 is formed of any suitable size, shape, and design and is configured to connect hanger 324 to base plate 310. In the arrangement shown, as one example, the pin 334 of base plate 310 is a generally cylindrical pin which extends downwardly at an angle from the bottom surface of base plate 310 of the drive truck. In the arrangement shown, as one example, at the lowest end of the pin 334, there is a threaded portion which is configured to receive at least one nut 338. In the arrangement shown, as one example, the hanger 324 is operably connected to the pin 334 of base plate 310 by placing a first nut 338 onto the threaded portion of the pin 334, placing a first bushing 336 on the pin 334, then placing the pin 334 with the first bushing 336 through an opening 340 in the hanger 324, then placing a second bushing 336 and washer onto pin 334 before threading a nut 338 (not shown) onto the threaded portion of the pin 334, thereby securely connecting hanger 324 to the pin of base plate 310. In this way, the pin of base plate 310 connects hanger 324 to base plate 310. In other arrangements, a single nut 338 is used at the end of the pin 334. In still other arrangements, no nuts 338 are used and the pin 334 and bushing 336 are press-fit into the opening 340 of the hanger 324.

In the arrangement shown, as one example, drive truck 306 includes a hanger 324. hanger 324 is formed of any suitable size, shape, and design and is configured to connect to base plate 310 and to axle 333. In the arrangement shown, as one example, hanger 324 is a generally elongated member which extends from a first side to a second side. In the arrangement shown, as one example, when viewed from a front or back end 206 of skateboard 200, hanger 324 may be generally triangular in shape, with the elongated section 342 of hanger 324 extending from near one opposing side 208 to near the other opposing side 208 of the skateboard and extending upward to a generally narrower portion which connects to the pin 334 of base plate 310.

In the arrangement shown, as one example, the elongated section 342 of hanger 324, which extends from near one opposing side 208 to near the other opposing side 208 includes axles 333 extending from either side. In the arrangement shown, the axles 333 do not rotate but rather provide a common axis from which the wheel assemblies 322 connect. The axles 333 are formed of any suitable size, shape, and design and is configured to receive the hub motors 366 of wheel assemblies 322. In this way, axles 333 extend along a common axis, thereby facilitating connection with both wheel assemblies 322 and hanger 324.

While drive truck 306 has been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that any other configuration of drive truck 306 may be used in order to connect base plate 318 to wheel assemblies 322.

Wheel Assemblies:

In the arrangement shown, as one example, drive unit 320 includes wheel assembly 322. Wheel assembly 322 is formed of any suitable size, shape, and design and is configured to facilitate powered movement of skateboard 200. In the arrangement shown, as one example, wheel assembly 322 includes a hub motor 366 and a wheel 308.

Hub Motor:

In the arrangement shown, as one example, wheel assembly 322 includes a hub motor 366. Hub motor 366 is formed of any suitable size, shape, and design and is configured to convert electrical energy from the battery 62 into powered rotational movement at the wheel 308. In the arrangement shown, as one example, hub motor 366 is coupled with axle 333 of the hanger 324. In the arrangement shown, the hub motor is press fit onto the axle 333 such that the interior portion (coupled to the stator of the hub motor 366) of the hub motor 366 remains stationary with the axle 333 of the hanger 324. In other arrangements, the hub motor 366 is placed over the axle 333 and secured by other means such as a fastener, a clip, or any other method. The outer portion of the hub motor 366 (coupled to the rotor of the hub motor 366) rotates about the interior portion when energized and provides the rotational movement necessary for powered movement of the skateboard 200. The hub motor 366 is electrically connected to the battery 62 and is coupled to the control assembly 68, either wired or wirelessly, and is configured to receive energy from the battery and signals from the control assembly 68 to selectively energize and de-energize the hub motor 366 for selective movement of the skateboard 200.

In the arrangement shown, as one example, hub motor 366 is generally cylindrical with a smooth outer surface. The hub motor includes a smooth outer surface that maximizes surface contact and friction with the interior of the wheel 308 and is configured such that the wheel 308 and the outer portion of the hub motor 366 move together. In other arrangements, the outer surface of the hub motor 366 includes interference protrusions that interface with corresponding protrusions and/or indentations on the interior of the wheel 308 to ensure common rotational movement between the outer portion of the hub motor 366 and the wheel 308.

Wheel:

In the arrangement shown, as one example, wheel assembly 322 includes a wheel 308. Wheel 308 is formed of any suitable size, shape, and design and is configured to operably connect to hub motor 366 and rotate in order to facilitate the powered movement of skateboard 200. In the arrangement shown, as one example, wheel 308 is press fit around the outer portion of hub motor 366 such that when the hub motor outer portion rotates, the wheel 308 rotates along with the outer portion of the hub motor 366. In other arrangements, the wheel may be securely coupled to the hub motor 366 by other means such as fasteners, clips, or any other method.

In the arrangement shown, as one example, wheel 308 is formed of a non-metallic material, such as polyurethane which is commonly used to make skateboard wheels, however any other non-metallic material, or even metallic materials may be used in order to form wheel 308. In the arrangement shown, as one example, wheel 308 is formed by a manufacturing process such as molding, however other processes such as machining, additive manufacturing, or the like may be used to form wheel 308.

In the arrangement shown, as one example, when system 300 is connected to a skateboard 200, wheels 308 are located on the opposing left and right sides 208 (and beyond in some arrangements) and located behind the front and rear trucks 212 of skateboard 200. In the arrangement shown, as one example, wheel 308 has a diameter which is large enough that, when system 300 is connected to a skateboard, the wheels 214 connected to the front truck 212 of skateboard 200 are lifted off the ground. In other arrangements, the drive truck is designed and/or positioned such that the wheel assemblies 322 lift the wheels 214 connected to the front truck 212 of skateboard 200 off the ground. In this way, only the wheels 214 connected to the rear truck 212 of skateboard 200 and wheels 308 of wheel assemblies 322 are resting on the ground. When the hub motors 366 of system 300 are operated, it causes the rotation of wheels 308, which causes skateboard 200 to move forward. As skateboard 200 moves, wheels 308 continue to stay in contact with the ground, as do the wheels 214 connected to the rear truck 212 of skateboard 200, however the wheels 214 connected to the front truck 212 of skateboard 200 still do not contact the ground in forward motion or when minor turns are made.

In the arrangement shown, the hanger 324 is able to rotate slightly about the pin 334 and bushing(s) 336. This rotation allows a user to lean the skateboard to the right and to the left and is configured to force the drive truck 306 to turn with respect to the longitudinal axis of the skateboard 200. In this way, the skateboard 200 reacts in a similar way the front truck 212 turns upon the user leaning when the drive unit 20, 320 is not attached to the skateboard 200 in normal use. As the user leans to the left, the skateboard 200 will lean to the left slightly, but the wheels 308 will remain even and in contact with the ground, urging the drive truck 306 to rotate slightly to the left, turning the skateboard 200. Similarly, as the user leans to the right, the skateboard 200 will lean to the right slightly, but the wheels 308 will remain even and in contact with the ground, urging the drive truck 306 to rotate slightly to the right, turning the skateboard 200.

Straps

In the arrangement shown, as one example, system 300 includes straps 24. Straps 24 are formed of any suitable size, shape, and design and are configured to securely connect system 300 to skateboard 200. In the arrangement shown, as one example, straps 24 are nylon straps which connect via buckles 124. However, straps 24 may be formed of any other material, such as polyester, plastic, polypropylene, or any other material which is adjustable, pliable, and durable and can be used to attach system 300 to skateboard 200. In the arrangement shown, as one example, straps 24 include buckles 124 at each end of straps 24. Buckles 124 are formed of any suitable size, shape, and design and are configured to securely attach the two ends of straps 24. In multiple arrangements, buckles 124 may be a side release buckle, a cam buckle, or any other buckle or mechanism which can be used to securely connect the two ends of straps 24. In another arrangement, straps 24 may be elastic straps that are able to be stretched over the deck 210 and trucks 212 of the skateboard 200.

In the arrangement shown, as one example, straps 24 extend around base plate 318 of system 300, thereby effectively attaching to system 300. In the arrangement shown, as one example, there are truck straps 128 and deck straps 130. Truck straps 128 are configured to connect system 300 so trucks 212 of skateboard 200, thereby securing system 10 in a longitudinal direction. Said another way, truck straps 128 wrap around front truck 212 and rear truck 212 of skateboard 200 such that system 300 is held securely and will not shift forward or rearward while system 300 is connected to skateboard 200.

Similarly, in the arrangement shown, as one example, deck straps 130 are configured to connect system 300 to deck 210 of skateboard 200, thereby securing system 300 in a lateral direction. Said another way, deck straps 130 wrap tightly around deck 210 of skateboard 200 such that system 300 is held securely and will not shift left or right while system 300 is connected to skateboard 200. With truck straps 128 and deck straps 130 wrapped around the trucks 212 and deck 210 of skateboard 200, respectively, system 300 is securely and tightly connected to skateboard 200 and will not move side-to-side or forward and backward while in use.

While straps 24 have been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that any other configuration of straps 24 may be used in order to facilitate connection of system 300 to skateboard 200.

In Operation

System 300 may be operated by a user to travel distances easily and effortlessly on a skateboard 200. First, a user provides a skateboard 200, which will generally have a deck 210, a pair of trucks 212 connected to the deck 210, and a pair of wheels 214 connected to each of the trucks 212. In this way, there is a front truck 212 with a pair of front wheels 214 and a rear truck 212 with a pair of rear wheels 214. The user can then attach system 300 to the skateboard 200.

In order to attach the system 300 to the skateboard 200, the user will take straps 24 and wrap them around skateboard 200 to secure system 300 to skateboard 200. Specifically, the user will take a truck strap 128, which is connected to system 300, and wrap it tightly around front truck 212, Once truck strap 128 is wrapped appropriately around the front truck 212, the user will use buckles 124 to secure the ends of truck strap 128 together, thereby securing system 300 to front truck 212. The user will then take a second truck strap 128, which is connected to system 300, and wrap it tightly around the rear truck 212. Once truck strap 128 is wrapped appropriately around the rear truck 212, the user will use buckles 124 to secure the ends of truck strap 128 together, thereby securing system 300 to rear truck 212. With truck straps 128 around both the front truck 212 and the rear truck 212, system 300 is attached to skateboard 200 such that system 300 will not move forward or backward while in use.

Next the user will take a first deck strap 130, which is connected to system 300, and wrap it tightly around deck 210 of skateboard 200. Once deck strap 130 is wrapped appropriately around the deck 210, the user will use buckles 124 to secure the ends of deck strap 130 together, thereby securing system 300 to deck 210. The user will repeat this process with additional deck straps 130 as needed. When completed, the user will have attached system 300 to deck 210 such that system 300 will not shift or slide side to side while in use. Importantly, deck straps 130 are generally located such that they will not get in the way of the user utilizing deck 210 for its intended purpose. That is, deck straps 130 can be placed such that they will not interfere with the feet placement of the user riding skateboard 200. In this way, system 300 provides attachment of a powered system to a skateboard without inhibiting the user's ability to actually use the skateboard 200, and more specifically the deck 210, as intended.

With the truck straps 128 and deck straps 130 wrapped securely around skateboard 200, system 300 is ready to be used to travel a distance. In the arrangement shown, as one example, with system 300 connected to skateboard 200, the set of rear wheels 214 are resting on the ground, as are wheels 308 of system 300, but the front wheels 214 of skateboard 200 are lifted off the ground due to the size and placement of wheels 308. Specifically, wheels 308 are located a behind front truck 212 and positioned spaced apart but centered about the opposing left and right sides 208 of skateboard 200. In this position, wheels 308 are close enough to the set of front wheels 214 and wheels 308 have a large enough diameter that wheels 308 cause front wheels 214 to be lifted off the ground.

In order to move, the user will utilize the remote controller 88 to send commands to control assembly 68 as described herein. Once control assembly 68 received the command from remote controller 88 to move forward, the control assembly will cause battery 62 to provide electricity to hub motors 366. With electricity provided to hub motors 366, hub motors 366 will begin to rotate, which will in turn rotate wheels 308. As wheels 308 rotate, the skateboard 200 is propelled forward. The user can use remote controller 88 to speed up or slow down the rate of travel of skateboard 200. Because of the rotatable nature of hanger 324, the user can travel in a straight direction and can also cause skateboard 200 to turn. During slight turns, the front wheels 214 of skateboard 200 will continue to stay off the ground, however if a sharp turn is made by the user, the front wheels 214 of skateboard 200 will make contact with the ground and provide additional support and stability during the turn.

Once the user reached their destination, the user can leave system 300 on the skateboard 200, or the user can remove system 300 from skateboard 200. The user can remove system 300 from the skateboard by unhooking buckles 124 on each of the truck straps 128 and each of the deck straps 130. The user will then unwrap the deck straps 130 from around deck 210 and, likewise, unwrap the truck straps 128 from both the front truck 212 and the rear truck 212. The user may desire to remove system 300 from skateboard 200 if the user has used system 300 to travel to a skate park and wants to skate and perform tricks using skateboard 200. In this way, system 300 can be used to travel distances, which still allowing the user to utilize skateboard 200 for more recreational or sporting use.
