Abstract: The present invention relates to a scooter that is self propelled with a uniquely designed spring winding propulsion system. Using a system of interrelated gears and sprockets, the propulsion system is automatically rewound as a user manually propels the scooter. Accordingly, when the propulsion system is sufficiently rewound, a release button transfers energy contained within the wound springs to a rear wheel thereby automatically propelling the scooter.

Abstract: The two skates steered by leaning sideways normally curve along circles of similar curvature. As the two circles are offset by the legs' distance they intersect. In order to avoid this disadvantage it is desirable that the outer leg's curved track has a larger radius than the inner leg's curved track. Using lean-controlled steered skates with tiltable wheels comprising a parallelogram closed fourbar linkage including two horizontal cross-guides the purpose is achieved by affixing the two cross-guides rotatably to extensions of the frame in such a way that the vertical projection of the rotation axis makes a solid angle with the vertical projection of the pivot axes of the closed fourbar linkage.

Abstract: The Elastomer Suspension System Skateboard Truck is proposed for use in all styles of skateboarding. This new design is unlike any conventional skateboard truck. The truck incorporates an elatomer suspension system, which is a modification of the type used in automotive vehicles and other mechanisms utilizing shock absorbing equipment. The elastomer shock absorbers oppose pressure from end to end, therefore diminishing or eliminating all forces associated with sudden or rapid motions. By downgrading or eradicating these extreme shock forces the skateboarder has more control, and is therefore more maneuverable.
