Hand or foot drive device for vehicles

摘要

The drive device converts the reciprocal-rotary motion of a drive wheel (or of two co-axial drive wheels of the same dia. fixed to each other) via linking cords, chains or belts and two idling wheels of the same dia. into the continuous rotary motion of a shaft or hub. One of the idling wheels takes over the drive of the shaft during the forward motion of the drive wheel, the other during its reverse motion. The drive wheel can be driven by two pedals fixed to it. The pedals are so shaped that a combined pressure force can be exerted by the front of the foot at the same time as a traction force is exerted by the heel, or vice versa.
