| Abstract: |
A powered walker for use by disabled persons in a standing position within the walker comprises a four-sided frame extending vertically upward from a platform with the frame being supported below the platform for transportational movement by a pair of front wheels, one of which is powered, and by a pair of rear wheels which can be turned for steering the walker. The driven front wheel is powered by an electric motor, the operation of which is controlled by the walker user who operates a switch which is electrically connected to the motor through a control circuit. Steering is effected by movement of a hand-operated tiller which is connected through linkages to the rear wheels. Hand-operated brakes are also provided. The walker carries its own rechargeable battery, as well as padded supports to aid the walker user.
