Dual powered propulsion system

摘要

The present invention relates to a rider's simultaneous use of his forearms/hands and legs to provide dual power into a propulsion system for riding a cycle vehicle, including a bicycle and a tricycle, or other vehicles. The invention permits the rider to have complete control turning the cycle vehicle, at will, right or left, while at the same time pumping a set of forearm/hand bars in an up power stroke and a down power stroke. In addition, even though the pumping action is lineally moving a telescoping rod and a push/pull cable back and forth, it is also simultaneously rotating a flywheel, upper and lower sprockets, and the crank axle to drive the bicycle wheel forward over the riding surface. Thus, the rider can provide maximum power into rotating the rear tire by simultaneously using both his arms and legs, while contemporaneously controlling his direction of travel.

主权项

1. An arm powered propulsion system for use with a cycle vehicle, the system comprising:
forearm/hand bars pivotally coupled to a cycle vehicle, wherein the forearm/hand bars are pivotal together in an up power stroke and pivotal together in a down power stroke; and a push/pull cable operatively coupled between the forearm/hand bars and a crank axle of the cycle vehicle, wherein the push/pull cable drives the crank axle of the cycle vehicle in response to movement of the forearm/hand bars in the up power stroke to provide power to the crank axle and the down power stroke to provide power to the crank axle.
