Abstract
A drive assistance device is disclosed to assist the occupants of ordinary manual weelchairs to propel themselves. Rather than grasping the grip rings secured to the main wheels of the wheelchair the drive assist provides laterally positioned handles upon which the propulsion force can be comfortably applied. The drive assist device can be simple removed for the wheelchair by the occupant when not required. The device does not require any modification of the ordinary wheelchair. The hub assembly components of the drive assist device are simply bolted to the ordinary wheelchair using the existing fastener arrangement and if necessary can be as easily unbolted and removed.
