The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A power operated invalid lifting and walking device controlled and propelled by the invalid and adapted to permit an invalid to lift himself between lying, sitting and standing positions comprising: a base having a pair of spaced legs with the terminal ends thereof being free of interconnection to permit unencumbered movement between said legs from said terminal ends; ground engaging members connected to said legs to permit rolling movement of said device; an upstanding support connected to said base at a location remote from said terminal ends having the upper end thereof vertically spaced from and substantially overlying said terminal ends to permit an invalid to stand on the ground between said legs under said upper end, said legs being constructed and arranged to permit same to straddle and pass under an invalid support whereby said upper ends extends over said support; a power operated hoist connected to said device; harness means connected to said hoist depending from said upper end for universal movement relative thereto and for connection to an invalid, said hoist being selectively operable to raise and lower said harness supported invalid between lying, sitting and standing positions; and means for operating said hoist removably attached to said device for control of said hoist by said invalid when in said supported standing position said harness and said control being substantially coextensively extendable from said device for remote control of said hoist by said harness supported invalid when in a position other than said standing position.
