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.
