ABSTRACT:
A device and method that will safely elevate a wheel chair to a greater height, hold the wheel chair in a safe elevated position and allow a person confined to the wheel chair to achieve the height of that of a standing person. The feet of the wheel chair are first rotated outward and lowered onto the floor, the wheel chair is then elevated by air pressure to a desired height and locked off for safety. When the wheel chair is being elevated or lowered, it will automatically lock off if the chair becomes unlevel for any reason.
