ABSTRACT:
A lift device particularly suitable for lifting handicapped persons with or without wheelchairs, into a vehicle or building. The lift can be incorporated into the doorway of any given vehicle, or into any step structure within a building. The lift, in its stowed position, forms the normal steps. The platform is made of four hinged parallel sections which can be withdrawn and folded into two steps. The second section which forms the upper step riser in the stowed position comprises two telescopically interconnected elements, and can be expanded to provide a wider platform. The fourth section which forms the lower step riser in the stowed position can be rotated to act as an access ramp along the forward edge of the platform and flipped upward to form an angle stop preventing the wheelchair from rolling backward during platform motion.
