Abstract
Abstract A combination chair/walker for aiding elderly and disabled in independent movement over a floor comprises an upstanding frame including a front rail, opposite sides and a back supporting a seat at an intermediate level for a person seated within the frame. An open space is provided forwardly of the seat for the legs of an occupant in both a standing/walking position and a seated position. The open space is defined between said front rail and said seat and a flexible crotch strap extends into the open space between the seat and front rail for preventing an occupant from sliding out of the seat onto the floor. Rollers are provided for movement of the frame over a floor and brakes are provided on at least some of the rollers to immobilize the chair/walker when desired. The front rail is movable between a closed and an open position for permitting a person easy ingress and egress to and from the chair/walker.
