Abstract:

The present invention is directed to a multi-purpose chair for the disabled that can be used as a passive wheelchair designed to be pushed by an individual to transport the occupant in a sitting position. By adjusting the heights of the legs, it will fit over conventional or handicapped commodes. Removing the legs with locking casters and inserting the stationary legs, the device can be used as a conventional chair. Additionally it can used a commode chair/raised toilet seat/safety frame. The device can also be used in a shower or by lifting one of the cantilevered armrests, and attaching the side bench, it can be used beside a bathtub. Covering the seat with the elastic seat-cover, the device can be used to transport individuals in public places without revealing the toileting applications. The novelty is that this all can be easily assembled or disassembled and carried in a FAA dimensionally compliant carrying case.

Abstract:

This application provides a mechanism that consists of right and left mounting bases that in different embodiments are adapted for mounting on a variety of different chairs. These mechanisms have roller tracks that have been designed on a radius with the fulcrum or pivot point positioned very close to where the center of mass is located, for a wide spectrum of different sized people from children through over-sized adults, to achieve varying degrees of movement. On the inside of the left and right mounting bases are curved slots that are parallel to the curvature of the roller tracks where guide members on the front and rear mounting brackets keep the seat and back rest from coming off the chair. There are front and rear rollers that traverse within the roller tracks that pivot on axles in the front and rear mounting brackets. In the curved slots on the sides are adjustable stop pins that limit the tilt or travel of the seat and back rest. A rack and spur gear mechanism is incorporated to manually adjust the position of the seat and back rest of the chair by rotating a crank handle. By removing the rack and spur gear mechanism and adjusting the stop pins the device will perform as a rocking chair. Turning a friction locking knob will lock the seat and back into a stationary position.
