TECHNICAL FIELDThe embodiments relate in general to skateboards generally used for recreational purposes.
BACKGROUNDConventional skateboards generally consist of a deck with front and rear wheel assemblies secured to the underside of the board. These wheel assemblies usually comprise a truck with an axle and two wheels. The decks are constructed of wood or a plastic material and are a finite length with a finite location of the wheel assembly. Conventional skateboards, and in particular longboards, are heavy and unwieldy to carry.
BRIEF SUMMARYDisclosed herein are embodiments of skateboard decks, each skateboard deck having a solid body of extruded aluminum, the body having a top surface, a bottom surface, a first longitudinal edge and a second longitudinal edge. A support member is carried by one of the top surface and bottom surface and is configured to strengthen the solid body along a length to support a skater. The support member extends parallel to a longitudinal axis of the solid body and spaced apart from each of the first longitudinal edge and the second longitudinal edge.
The support member can be extruded with the solid body or can be attached with attachment means. The support member can be a thickened region, one or more ridges, one or more rails, each of which can extend along only a portion of the length of the solid body or along the entire length of the body to provide the requisite support to the thin solid body to support the skater.
These and other objects, advantages, and features of the invention will become apparent to those persons skilled in the art upon reading the details of the embodiments as more fully described below.
The invention is best understood from the following detailed description when read in conjunction with the accompanying drawings. It is emphasized that, according to common practice, the various features of the drawings are not to-scale. On the contrary, the dimensions of the various features are arbitrarily expanded or reduced for clarity. Included in the drawings are the following figures.
The top surface 12 of the unitary body 10 is configured to support a skater. The bottom surface 14 of the unitary body 10 is configured to retain truck assemblies 20, as seen in
The skateboard deck 5 in
The handle portion 22 is configured to receive one or more fingers of the skater. The handle portion 22 can be an elongated aperture sized to receive four fingers of the skater. As another example, and shown in
The deck 5 in
By extruding the unitary body 10 with the truck rails 40, 42, the remainder of the unitary body 10 can be thinner than without the truck rails 40, 42. The truck rails 40, 42 provide support to the thinner unitary body 10 that would otherwise need to be obtained through a thicker cross-section of the body 10.
Each truck assembly 20 can include a baseplate 50 and a hanger 52, which have bushings in between. A bolt or kingpin 54 holds these together and can be tightened or loosened to adjust the turning and stability of the truck assembly 20. The hanger 52 also supports the axle on which wheels 56 are mounted.
The baseplate 50 of the truck assembly 52 is a guide portion that is movably receivable in the track 48 and selectively positionable along a length of the track 48.
The truck assemblies 20 can be attached at the determined position within the track 48 by tightening fasteners 62 through fastener apertures within the baseplate 50 against the bottom surface 14 of the body 10 within the track 48. The fasteners 62 can be screws, clips, pegs, nails, or any other member capable of anchoring the baseplate 50 to the unitary body 10 of the skateboard deck 10. As a non-limiting example, the fasteners 62 are screws with a hex head (compatible with an Allen wrench kit). The fasteners 62 are inserted into apertures in the baseplate 50 and attach the truck assembly 20 to the unitary body 10 by tightening fasteners 62 against the bottom surface 14 within the track 48. The apertures and fasteners 62 can be threaded. By tightening the fastener 62 against the bottom surface 14 rather than inserting fasteners into predetermined receivers along the track, the available positions along the track 48 for the trunk assemblies 20 is not restricted.
The track 48 can be configured and sized to allow a certain standard size truck assembly to be used with the deck 10 or can require custom truck assemblies for use with the skateboard deck 10. If the truck assemblies are standard-sized, a skateboard assembly 1 can include a tap which can alter the size of the pre-drilled holes to a size that would allow use with the fasteners 62 provided with the skateboard deck 10.
Another embodiment of a skateboard deck 5 includes a first channel 70 formed adjacent the first truck rail 40 and a second channel 72 formed adjacent the second truck rail 42. Each channel 70, 72 may receive a protective strip 74, as illustrated in
As shown in this embodiment, the truck rails 40, 42 are T-shaped to provide both the track 48 and the channels 70, 72. However, this is a non-limiting example. The truck rails 40, 42 need only provide a side support for the channel and can be any other shape that provides the side support. The walls 76, 78 are also illustrated as L-shaped. However, this is a non-limiting example and may be any other shape that provides side support to the channel 70, 72.
The channels 70, 72 may be left empty, with the walls 76, 78 adding additional support to the unitary body 10, as shown in
The protective strip 74 can be held in the channels 70, 72 with a friction fit, with adhesive, due to the shape of the walls 76, 78 and truck rails 40, 42, or any other means known to those skilled in the art.
Because the truck rails 40, 42 and walls 76, 78 are extruded with the unitary body, the contoured unitary body 10′ can be extruded with one or both of the truck rails 40, 42 and walls 76, 78 as shown in
It is difficult to manufacture an extruded aluminum skateboard having the requisite length and thickness such that the board is light and provides the flex required by today's athletic users while supporting the weight of the user and withstanding forces asserted against the skateboard by the user while freeriding, cruising and sliding, for example.
The support member 112 provides strength to the solid body 10 along its length so that the body 10 can be kept as thin and flexible as possible for the user. The support member 112 can be extruded with the body 10 or can be attached to the body by any known attachment means, including but not limited to adhesion, welding and the use of fasteners.
The support member 112 can be one or more of tracks, rails, beams, cylinders, rods, bars, ridges, channels, grooves or other similar means that provide the necessary support along the length of the body 10. The support member 112 can extend along an entire length of the body 10 or can extend along only a portion of the length. The support member 112 can also be intermittent along the length of the body 10. As a non-limiting example, the support member 112 can extend over 5% to 100% of the length of the body 10. The support member 112 will be aluminum when extruded with the solid aluminum body 10. However, the support member 112 can be any suitable material that provides the requisite support when attached to the body 10 by other means, such as another metal or fiberglass. The truck assemblies 20 can be attached to the body 10 in an area without the support member 112, the support member 112 can be modified so that the truck assemblies 20 can be attached to the body 10 where the support member 112 is, or the truck assemblies can utilize the support member 112 for attachment to the skateboard deck.
The rails 40, 42 shown in
The ridges 118 of the support member 112 can be close enough together so that the upper surface 120 of the support member 112 is stood on directly by the user. Alternatively, the upper surface 120 of the support member 112 can be covered with grid tape or sandpaper for traction. The ridges 120 can be of the same width and height across the width of the body 10′. Alternatively, the ridges 120 can increase in height and/or width toward the longitudinal axis of the body 10′ as illustrated in
In some embodiments, the support member 112 is spaced on either side from longitudinal edges 16, 18 of the body 10, 10′ to avoid adding any thickness to the longitudinal edge portions of the body 10, 10′. Keeping the support member 112 spaced from the longitudinal edges 16, 18 provides as much clearance with the ground as possible, in turn providing the most flexibility for the user when doing tricks, sliding, etc.
The figures are provided by way of illustration and are not meant to be limiting. The skateboard decks disclosed in
As discussed, the support members 112 disclosed herein enable the extrusion of a skateboard, longboard or cruiser having a length between about 28″ and 48″, while keeping the skateboard deck flexible and lightweight. For example, the weight of the skateboard decks can be 5 pounds or less. In further examples, a 48″ extruded aluminum skateboard deck can weigh less than or equal to 4.75 pounds, while a 32″ extruded aluminum skateboard deck can weigh less than or equal to 3.2 pounds.
The ability to manufacture such lightweight skateboard decks allows for increased bounce and flexibility of the deck. When the support member 112 is extruded with the body 10, 10′, the skateboard deck can feature a convex bend upward from the middle to further improve the bounce and flex of the deck. For example, the convex bend upward can be about 0.5 inches.
The above-described embodiments have been described in order to allow easy understanding of the invention and do not limit the invention. On the contrary, the invention is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims, which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structure as is permitted under the law.
