ABSTRACT:
An invalid walker has a frame in the form of a seat and seat back with arms and telescopic legs depending from the arms. An air compressor is provided on the seat back for extending and retracting the legs under occupant control so as to raise and lower the walker as between occupant-seated and occupant-standing positions. A removable front section is provided for the walker to enclose the occupant and form a safety constraint. A reinforcing ring with auxiliary stabilizing wheels is provided around the bottom of the legs. An occupant may use the device in a seated or standing position to assist in walking with the occupant's feet in ground engagement.
