Abstract:
A hand propelled wheeled vehicle, specifically a wheelchair, containing a pair of hand actuated, lever driven mechanisms to rotate the main wheels. The levers pivot around attachment points on the left and right sides of the vehicle chassis. The left lever actuates a frame responsible for contra-rotating two integral one-way clutches arranged on a drive shaft coupled to the left main wheel, with the right lever operating the right side mechanism in an identical fashion. The arrangements of the clutches utilize both the forward (pushing) and backward (pulling) stroke of the lever to rotate the main wheels forward. Steering and braking control is afforded through attachments integral to the hand grips of the right and left hand levers, respectively.
