ABSTRACT:
A wheeled vehicle and propulsion device therefor is provided comprising an elongated pole, and at a first end of said pole, a handle for manipulation by the operator of the vehicle. At a second end of the pole is a ground engaging element for frictionally engaging the surface over which the vehicle is to be propelled. This ground engaging element includes a wheel member, and a clutch interconnecting said wheel member with said pole, the clutch device constructed so that the wheel turns freely in one rotational direction, but resists turning in the other rotational direction. Thus, when said ground engaging element is pushed against said surface in one direction, thrust from said handle is transmitted through the pole, through the wheel member and to the ground so that said vehicle is urged in the opposite direction, but when said wheel member is permitted to merely roll along the surface, the wheel member rotates freely.
