Abstract: An apparatus for facilitating user propulsion of a wheelchair having a frame for supporting a user and a pair of rear wheels that rotate about an axis. The apparatus includes a handgrip having an outer surface and an opposite, inner surface such that when a radial force relative to the axis is applied to the outer surface by the user the inner surface is configured to engage a rear wheel in the pair of rear wheels such that the rear wheel can be rotated and the wheelchair propelled. A pair of coupling members configured to couple the handgrip to the frame and hold the handgrip in a neutral position, and the pair of coupling members are further configured to alternately increase in length and become tensioned as the user moves the handgrip away from the neutral position to rotate the wheel.

Abstract: A wheelchair propulsion and contamination reduction arrangement permits the user to drive the chair on the main ground-engaging rear wheels with a compressible wheel cover that is grasped and squeezed against the wheel to provide propulsion and mounted with elastic tension devices on opposite ends that return the drive grip to a neutral position when the user relaxes the compression. The compressible device is a polymeric foam which can also be adapted to carry one or more of a lubricant, cleaner and biostatic treatment.
