Abstract

Abstract The invention herein disclosed relates to a coaster vehicle comprising a body having a rider compartment with handrails running along the top lateral edges of said compartment. The body of the vehicle is continuously curved upwardly and outwardly in transverse cross-section and decreases in width from the rear to the front. Mounted on transverse axes adjacent to the front and rear end of the body and projecting outwardly through openings in the bottom thereof are spherical rollers, the centers of which lie in the longitudinal vertical plane of the vehicle. By reason of these spherical rollers the vehicle will operate on a surface having a high coefficient of friction. Steering is effected by the rider leaning to one side or the other to effect drag of the bottom portion of the vehicle.
