Description

FIELD OF THE INVENTION

[0001] The present invention relates generally to the area of skateboards, and more particularly, to a riser pad that improves a board's tilting capabilities by increasing the distance between the skateboard truck and the board, reduces road vibrations, and is able to be used in all standard skateboard trucks.

BACKGROUND OF THE INVENTION

[0002] Skateboards are commonly used for recreation and competition purposes. Typical skateboards comprise an elongated board supported on two wheel truck assemblies containing two wheels each. Skateboard truck assemblies in the prior art typically include a mounting plate, which connects the truck assembly unit to the underside of the skateboard, and some type of bracket to bridge the axle assembly and wheels to the mounting plate. The skateboard rider balances on the board and adjusts the direction of travel by adjusting the pressure of his weight at various locations on the board.

[0003] Riders of skateboards each have a plurality of tricks that can be performed on a wide variety of surfaces, such as flat surfaces, rough terrain, edges of elevated objects, rails and other small profile elongated objects. While performing a multitude of tricks on a variety of surfaces, a rider may wish to adjust his direction of travel dramatically. In order to do so, he must apply a majority of his weight to one side of the board, causing the board to tilt at an increased angle. Generally, the rider's ability to adjust his direction of travel will depend on the angle in which the board is tilted. As the rider increases the board's angle of tilt, his ability to adjust his direction of travel increases as well. Riders are limited, however, in their ability to maximize a board's tilt by at least two factors. First, a rider is limited in his ability to maximize a board's tilt due to the limits of the particular truck assembly unit. While truck assemblies have been improved to provide, among other things, maximum tilting capacity, they are limited since the distance between the truck assembly unit and the board is minimal and hampers effective tilting. Second, a rider is limited in his ability to maximize a board's tilt due to the inevitable point at which the edge of the board touches the ground.

SUMMARY OF THE INVENTION

[0004] What is needed then is a skateboard that maximizes the angle by which the board can be tilted. Also needed is a board that features an increased distance between the board and the truck, so that the angle by which the board can be tilted can be maximized.

[0005] In accordance with this invention, herein is provided a skateboard comprising a deck having a top surface and a bottom surface, a truck assembly unit attached to the deck, means for attaching the truck assembly unit to the deck, a riser pad located between the deck and the truck assembly unit, wherein the riser pad comprises a planar member made from a material selected from the group consisting of rubber, plastic, metal alloy, and combinations thereof. The planar member can contain 4 elongated holes whereby the means for attaching the truck assembly unit can pass.

[0006] In accordance with another embodiment of this invention, herein is provided a method for performing skateboard tricks using a skateboard comprising a deck having a top surface and a bottom surface, a truck assembly unit attached to the deck, means for attaching the truck assembly unit to the deck, a riser pad located between the deck and the truck assembly unit, wherein the riser pad comprises a single planar member made from a material selected from the group consisting of rubber, plastic, metal alloy, and combinations thereof, and wherein the planar member can contain 4 elongated holes whereby the means for attaching the truck assembly unit can pass through.

DETAILED DESCRIPTION OF THE INVENTION

[0012] While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that may be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

[0013] One embodiment of the invention is shown in FIG. 2. According to FIG. 2, a skateboard deck 18 is shown supported upon a pair of truck assembly units 10a, 10b, each containing a riser pad 42 in between the deck 18 and the truck assembly unit 10. Generally, the skateboard contains a deck 18 having a top surface and an underside 24 or bottom surface. The deck 18 may be made out of virtually any substance useful for making skateboards, including, but not limited to, metal, glass, fiberglass, plastic, wood, and the like and combinations thereof. The deck 18 may serve as a location in which the rider can choose to place a portion of his body thereon, thereby controlling his direction by adjusting the amount of weight applied to the board. The deck 18 may be any shape, size, or color, as long as it is conducive to supporting at least one truck assembly unit 10 and a riser pad 42.

[0014] Any truck assembly unit 10 may be used according to an embodiment of this invention. Generally, the truck assembly unit 10 refers to the wheels and supporting structure that is generally located under, and attached to the deck 18. The truck assembly unit 10 usually includes an axle with at least two wheels encased in an axle assembly unit 16. The truck assembly unit 10 may be made from virtually any material, but usually is fabricated of a light weight metal alloy, including for example, aluminum and/or titanium. Also, high impact plastics or polymers or copolymers may be used to fabricate the device. Truck assembly units 10 are generally attached to the skateboard deck 18 by any method known in the art, and can be attached using means for attaching the truck assembly unit to the skateboard deck, such as for example, screws, bolts, pins, nails, and the like, and combinations thereof.

[0015] The general features of a skateboard truck assembly unit 10 are shown in FIG. 1, which includes a mounting plate 12, a mounting bracket 14, and an axle assembly unit 16. A kingpin 32, also known as a tension bolt, is inserted through apertures 20 and 21 to connect the axle assembly unit 16 to the mounting bracket 14 and the mounting plate 12. Generally, the mounting plate 12 and mounting bracket 14 are unitary structures, though they can constitute separate components under the desired circumstances. The truck assembly unit 10, particularly the axle assembly unit 16 may be fabricated of any light weight metal allow, including for example, aluminum and titanium. High impact polymers or materials made of carbon fiber may also be used.

[0016] As used in this disclosure, the term “riser pad” refers to any device that may be used to increase the space between the truck assembly unit and the deck. Generally, riser pads may be in any shape, size, or color. In accordance with one embodiment of this invention, riser pads may be shaped to conform with the shape of the portion of the truck assembly unit that attaches to the skateboard. Riser pads may be useful in the present invention located between the truck assembly unit and the deck. Riser pads useful in the present invention generally do not protrude from the truck assembly unit, but may slightly, for example, so as to allow for information (such as for example, a trade name) to be etched upon the surface that is not covered by the truck assembly unit.

[0017] Riser pads useful in the present invention may be made from virtually any material. Generally, the material is selected from the group consisting of rubber, plastic, metal alloy, and the like and combinations thereof. In one embodiment of the present invention, the riser pad contains rubber and has one or more holes in its planar member. The holes make it convenient for attaching the truck assembly unit to the deck, since the means for attaching the truck assembly unit to the deck can pass easily through the riser pad. In another embodiment of the present invention, the riser pad has four elongated holes, so that the riser pad may be used with standard skateboard trucks, no matter the size. The elongated holes of the riser pad are useful for lining up the riser pad to fit the holes typically found in truck assembly units, thereby allowing the riser pad to be centrally placed between the truck assembly unit and the deck. In addition, the elongated holes allow for the riser pad to be adjusted so as to prevent protrusion of the riser pad from the truck assembly unit which may inhibit certain sliding tricks.

[0018] As shown in FIG. 1, a riser pad 42 is located in between the mounting plate 12 and the deck 18. In one embodiment, the riser pad 42 is approximately 2.25 inches in width and 3.25 inches in length. Apertures 44 in the riser pad 42 are provided to receive screws or bolts 22 to secure the truck assembly unit 10 to the deck 18, by using a nut 30 or any other suitable means for this purpose. These apertures 44 are typically elongated so as to receive a range of sizes and types of truck assembly units. In one embodiment, the apertures 44 are approximately 0.5 inches long and 0.25 inches in width. In one embodiment, the outer edges of the apertures 44 are disposed approximately 0.125″ from the outer edges of the riser pad 42. The mounting plate 12 is provided to secure the truck assembly unit 10 to the riser pad 42 and to the deck 18. Apertures 40 in the mounting plate 12 are provided to receive screws or bolts 22 to connect the mounting plate 12, by using a nut 30 or any other suitable means for this purpose, to the riser pad 42 and to the underside 24 of the deck 18.

[0019] Typically, skateboard 18 will include two truck assemblies, as shown in FIG. 2, one assembly 10a mounted to the underside 24 of deck 18 in the front section 24a of the deck 18 and a second truck assembly unit 10b mounted to the underside 24 of deck 18 in the back section 24b of the deck 18.

[0020] As shown in FIG. 1, the axle assembly unit 16, which is normally a unitary structure, includes central portion 16a and a main axle comprising axle rods 16b and 16c, which extend away in opposite directions from central portion 16a. Wheels can be mounted on axle hubs 26 and 28 of axle rods 16b and 16c, respectively. Wheels can be secured by a nut 50 or any other suitable means for this purpose. The present invention can accommodate wheels of different sizes. The head of kingpin 32 is located in a recessed area 36 of the central portion 16a of the axle assembly unit 16.
