Abstract:

A pedal drive system imparts a rotational force, in part, through linear travel of the pedal. The system comprises parallel, dislocated first and second rotating shafts. A first left sprocket and a first right sprocket are each mounted on the first shaft. A second left sprocket and a second right sprocket are each mounted on the second shaft. A left chain is looped around the first left sprocket and the second left sprocket and engages the teeth of those sprockets. A right chain is, likewise, looped around the first right sprocket and the second right sprocket and engages the teeth of those sprockets. A right pedal is affixed to the right chain, and a left pedal is affixed to the left chain. The first shaft is affixed with a forward sprocket for rotation with the first left and first right sprockets. A driven wheel is affixed with a rearward sprocket.
