US Patent 11447204 Mobility vehicle

A pump-action mobility vehicle may include a pumping arm attached to a foot slide. As the pumping arm is actuated, the foot slide moves forward and rearward in response to the pumping action. The foot slide may be connected to a drive mechanism that selectively engages a chain or belt that loops around a drive wheel arranged on an axle of the vehicle. When the drive mechanism catches and moves the belt or chain in a forward direction, the axle rotates in a forward direction to drive the vehicle forward. A reverse mechanism may also be provided that selectively causes the drive mechanism to catch and drive the belt or chain in an opposite direction.
