Abstract
A power assist apparatus that converts a hand-propelled wheelchair to a motorized wheelchair without the use of tools or mounting brackets. The apparatus has a motorized mechanism, a pair of outrigger assemblies, pivot mechanisms and position sensors. The motorized mechanism has a battery, a control mechanism and a pair of motorized sections that each have an electric motor and a wheel. The outrigger assemblies have arms that support the drive wheels of the wheelchair above the surface to be traversed. The position sensors determine movement of the outrigger assemblies or a wheel support mechanism attached thereto in response to rotation of the drive wheels by the occupant and transmit data to the control mechanism to operate the motors to move the wheelchair in the direction indicated by the drive wheels, thereby controlling movement of the apparatus in the same manner as the hand-propelled wheelchair.
