ABSTRACT:
A convertible lift mechanism lifts a person or an object from a first surface to a vertically displaced second surface. The convertible lift mechanism includes a source of motive force, a scissor lift linkage, and a conversion stair. The conversion stair has a first configuration in which it functions as a stair and a second configuration in which it functions as at least a portion of a lift platform. When the conversion stair is in the first configuration, the convertible lift mechanism functions as a stairway. When the conversion stair is in the second configuration, the convertible lift mechanism functions as a platform lift or wheelchair lift.
