  • Patent number: 4453729
    Abstract: A wheelchair having a frame capable of supporting the occupant includes a plurality of wheels including two driving wheels. Left and right side levers are mounted on the wheelchair such that the tops of the levers can be moved back and forth reciprocally toward and away from the occupant of the wheelchair. When the levers are in a position towards the occupant of the wheelchair, they are in a neutral position and by pushing away from the occupant from the neutral position to a displaced position, a power stroke is performed. Movement of the levers in the reverse direction back toward the occupant constitutes a return stroke of the same. A power transfer mechanism includes a first and second ratchet operatively associated with each of the driving wheels. The first ratchet allows the driving wheel to free wheel at all times in a forward direction.
