Abstract: An improved track device includes rail tubes and rail tube supports forming tracks separated by cross members and joined at ferrules in embodiments having offset ferrules and embodiments having staggered ferrule joints.

Abstract: Embodiments of a track device include a track section with a hollow rail, a rail support member with flanges, eccentric rail support, a cross member with a rotatably coupling, rail ferrules for mating, and rail materials including a lubricious material.

Abstract: A track device includes rails and cross-members capable of supporting a carriage with wheels such as a car, dolly or cart.

Abstract: The track system of the present invention provides dolly track whose joints are substantially seamless, providing a substantially smooth riding surface over the entire length of joined sections of track. The ferrule design of the invention provides ridged piece to piece joining, eliminating pinching and hinging points. This allows multiple assembled track pieces to be moved without damage. The system uses self locking track buckles. A folding cross member system may be folded for ease of movement and placement. In one embodiment, the track is comprised of a carbon fiber hybrid composite with lighter weight and greater strength than prior art steel or aluminum tracks. In addition the track of the present invention does not bend, eliminating the need to reshape or repair the track each time before use.

Abstract: A grip head includes a progressive support clamp, a biscuit clamp and a ball joint. The progressive support clamp can be actuated from an open position to a support member clamp position. The support member clamp position clamps a support member in a support member channel defined in the progressive support clamp and allows rotation of a ball of the ball joint, to enable positioning of an accessory coupled with the ball. The progressive support clamp can be further actuated to a full clamp position. The full clamp position clamps the support member and fixes the position of the ball and the position of the accessory coupled therewith.

Abstract: The invention is an apparatus and method for attaching a pair of light assemblies to a skateboard. The assemblies are attached by removing the bolts that attach the trucks to the deck, aligning each assembly with a truck, and re-attaching the bolts so that there is a truck in between the deck and light assembly. The assemblies have a lid that can be opened to expose a chamber housing a battery to power the light generative apparatus (e.g. LEDs or light bulbs or equivalents) at the end of each assembly. To turn on or off the lights, a user alternately taps on the lid of each assembly or uses a switch in each assembly. Alternatively, the front and back assemblies are connected by a flat horizontal structure that has a sensor for receiving tapping pressure to turn on or off the lights.
