A device and method that will safely elevate a wheel chair to a greater height, hold said wheel chair in a safe elevated position and allow a person confined to said 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.

A wheel chair for transporting and supporting a disabled person on and above a floor and further elevating said wheel chair while said disabled person remains supported by said wheel chair comprising: cylinders, each said cylinder with an uppermost end and a lowermost end; said cylinders, wherein said cylinders are nearer to each other at their said uppermost end and wherein said cylinders are sloping away from each other to where they are further apart from each other at their said lowermost ends; said cylinders, wherein said cylinders are further curved; support members, wherein said support members are fixed to said cylinders, fixing said cylinders in a position relative to each other; A frames, said A frames are formed by said cylinders and support members and wherein there are two said A frames and wherein each said A frame is disposed on each side of said wheel chair; A seat, said seat is disposed between each of said A frames and said seat is further fixed to said support members; leg means, said leg means with an upper end and a lower end, wherein said leg means are slideably disposed on the inside of said cylinders and wherein said upper end of said leg means forms on air tight connection between said inside of said cylinder and said upper end of said leg means and wherein said leg means telescopes in and out of said cylinder, said leg means are further curved to further conform to said curve of said cylinder, to allow said leg means to move inside of said cylinders; a pump, said pump is disposed on said wheel chair; tubes, said tubes essentially connecting said pump to said cylinders; wherein said pump is actuated by said disabled person while said disabled person is supported on said wheel chair, said pump thereby forms air under pressure into said tubes, and said air under pressure is conducted through said tubes and into said cylinders, thereby increasing the pressure within said cylinders which further reacts on said leg means actuating said leg means to further extend from said cylinder, thereby causing said wheel chair supporting said disabled person to elevate.
