Abstract

A power assist apparatus that converts a hand-propelled wheelchair to a motorized wheelchair without use of tools or mounting brackets. The apparatus has a first motorized section and a support assembly associated with one drive wheel of the wheelchair and a second motorized section and a support assembly associated with the other drive wheel. The motorized sections, each having a motor and a wheel, are connected together but operate independently. Each support assembly has an outrigger assembly with outwardly extending arms that support the drive wheels above the surface to be traversed. The apparatus has a control mechanism controlling the motors and a positioning sensor mechanism determining movement of the outrigger assemblies to transmit positional information to the control mechanism and move the apparatus and wheelchair in the direction indicated by the drive wheels, thereby controlling movement of the apparatus in the same manner as the non-motorized wheelchair.
