A walker apparatus for disabled persons is comprised of a frame having a pair of spaced-apart wheels mounted at a front end thereof. A seat is secured to the frame rearwardly of the front end. The wheels are connected to a steering assembly having a tandem connecting linkage to cause the wheels to turn in parallel relationship. Handles are secured to the steering assembly to control the position of the wheels for guiding the apparatus during displacement thereof. A rear support wheel is secured to the frame and disposed behind the seat and substantially central between the pair of spaced apart wheels. The apparatus is motorized by the feet of the disabled person when sitting on the seat and grasping the steering handles. The walker apparatus may also be collapsible and may also be provided with a retractable pusher arm secured behind the seat whereby the apparatus may be displaced by an attendant person pushing the apparatus while the disabled person is seated on the seat with his feet disposed on a retractable foot rest plate. |
