ABSTRACT:
A lift chair or elevator chair apparatus for invalids provides a base portion having an inclined upper surface and a sub-frame pivotally attached thereto along a forward edge. A mechanical ram powered by an electric motor pivots the sub-frame with respect to the base and about the forward pivot. The inclined upper surface of the base receives the sub-frame thereon in a fully downward position which defines a reclined position for the user. Pivotal rotation of the sub-frame with respect to the base and upon the pivot to an uppermost position defines the forward most lifting position which aids the invalid in moving from a sitting to a standing position.
