A waveform reinforced skateboard deck with an intermediate body extending between a nose end and an opposing tail end, the deck further including an outermost top rider bearing surface and an outermost bottom truck mounting surface with at least a portion of at least one of the surfaces having a plurality of spaced apart elongated waveforms defining peaks and troughs projecting along a substantially sinuous path between the nose and tail ends.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.

A skateboard system includes a first suspension member having first through third portions, each portion having a largest flat planar surface. The first portion includes a plurality of mount holes to mount it with a skateboard deck. The largest flat planar surface of the second portion is angled between fifteen and sixty degrees relative to the largest flat planar surface of the first portion and relative to the deck. The largest flat planar surface of the third portion is angled between fifteen and eighty degrees relative to the largest flat planar surface of the second portion. The third portion includes at least one opening to mount a truck assembly and/or a hanger with the third portion. The first suspension member flexes, such that an angle between the largest flat planar surface of the second portion and the deck decreases, in response to a first downward force on the deck.

A rotation powered vehicle drive mechanism includes an elongated chassis slot disposed within a respective lateral exterior portion of a chassis assembly. An elongated platform slot is disposed within a respective lateral portion of a platform assembly, and is configured such that it is substantially opposed to the chassis slot. The platform assembly is pivotally secured to the chassis assembly thereby allowing for rotation through a platform rotation angle of the platform assembly with respect to the chassis assembly about a rotation axis. The rotation of the platform assembly results in an increase or decrease of a variable slot height which is measured between the chassis slot and the platform slot. A cart assembly is disposed between the chassis assembly and the platform assembly, and is operatively coupled to the chassis slot and to the platform slot. The cart assembly has a cart height and is constrained by the chassis slot and the platform slot to a position on the chassis assembly wherein the cart height is substantially equivalent to the variable slot height. In this manner the cart assembly is configured to translate along the chassis assembly upon rotation of the platform assembly with respect to the chassis assembly. A helical drive shaft is rotationally secured within the chassis assembly and operatively coupled to the cart assembly such that translation of the cart assembly results in rotational motion of the helical drive shaft. A truck assembly is pivotally secured to the chassis assembly. The truck assembly includes an axle rotationally secured to the truck assembly and operatively coupled to a plurality of wheels. The axle is operatively coupled to the helical drive shaft such that rotation of the platform assembly with respect to the chassis assembly in a first angular direction results in rotation of the axle and respective wheels in the first angular direction.

One embodiment of a skateboarding balance device where an elongated structure (10) has four straps (16L, 16R) disposed thereunder said structure. This pad (10) is composed of flexible material. The straps (16L, 16R) provide for a method of securely attaching said pad (10) to a skateboard (SK1) by means of velcro (20L, 18R). The straps are made of material with elasticity.

The present disclosure provides a detachable training wheel apparatus for mounting to the underside of a skateboard tail or nose to assist with balancing a user during manoeuvres which require tipping of the skateboard onto two wheels, while allowing the board to continue rolling along the ground with minimal friction. The apparatus comprises a single wheel mounted to a mounting board by a pair of supports and a central bushing, with the opposing side of the mounting board having a flat surface provided with attachment means for detachably coupling to the skateboard underside, such as a hook and loop surface.

A truck carrying member for coupling a conventional truck to a skateboard is described. The truck carrying member has comprises with a base plate rotatably coupled a pivoting plate at a pivot. The pivot comprises a bolt that provides an axis of rotation and a biasing member that keep that base plate and pivoting plate centered position. The base plate has a first mounting surface and a first pivoting surface that form a first obtuse angle. The pivot plate has a second mounting surface and a second pivoting surface that form a second obtuse angle that is less than the first obtuse angle. The second mounting surface extends downward from the skateboard when the truck carrying member is attached to a bottom surface of the skateboard. The pivot and biasing member help increase maneuverability of the skateboard by allowing the wheels of the truck to tuck in closer to the deck during turns.

A customizable skateboard truck assembly comprising an adjustable base plate and a hanger with both adjustable rake and ride height. Further, the skateboard truck assembly disclosed utilizes an open bushing platform that allows for unlimited shapes to be used for the bushing relative to its perimeter. The added space between the hanger and the baseplate allows the truck assembly to fit multiple bushing thicknesses while also choosing to maintain or change the hardness for the bushing. The thickness, hardness, and shape of the bushing all have an effect on the truck assembly's responsiveness and feel for the user. Additionally, the truck assemblies comprise adjustable cams for regulating rotation, or in other words, providing a maximum angle of rotation to the hanger to avoid wheel bite, thereby increasing safety an control of the skateboard by the user. The customizable skateboard truck assembly facilitates smooth and precise motion of the skateboard.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

A skateboard or longboard truck having configured to couple with a deck of the skateboard or longboard. The truck including a base and a hanger. The hanger disposed within a hanger aperture of the base. The hanger rotatably coupled with the base by a pivot assembly. The rotation of the hanger with respect to the base controlled by a compression assembly.
