Abstract
A fully steerable skateboard generally comprises an elongate chassis rollingly supported by a pair of front wheels and a pair of rear wheels. Each wheel rotates about a substantially horizontal axis for rollingly supporting the chassis and rotates about a vertical axis for steering the chassis. A steering mechanism attached to the chassis and to the wheels steers the wheels in response to movement of a rider's foot. The wheels at all times define a stable support plane for said skateboard. Each said wheel is rotatable through 360 degrees. Braking is accomplished by rotating a wheel set ninety degrees to the direction of travel. According to a preferred embodiment, the wheel steering mechanism includes a pair of foot platforms for supporting a rider's feet. Steering linkage connects each foot platform to a set of wheels such that rotation of each foot platform steers the wheels. The chassis has an underside that forms a plane such that obstacles can only strike a wheel below its axle.
