| 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.

1. A powered walker which comprises: an upstanding rigid frame assembly comprising interconnected, rigid frame members defining (a) vertical sides which define a vertical space for receiving a user's body and defining (b) an entryway in one side thereof, said frame assembly connected to and terminating at its lower end in support means for supporting a walker user thereon in standing position within said frame assembly; a gate hingedly connected to said frame assembly along one side of said entryway and sized to extend across said entryway for closing engagement with said frame assembly along the opposing side of said entryway; wheel means connected to said frame assembly for supporting said frame assembly above a surface for transportational movement thereover, said wheel means comprising a pair of independently-mounted front wheels and a pair of interconnected turnable rear wheels; electrical power means carried within said frame assembly; drive means connected to said electrical power means and to one of said front wheels; switch means mounted adjacent the upper end of said frame assembly for manual operation by a walker user and electrically connected to said electrical power means; steering means connected at a lower end to said rear wheels and rotatably connected at its upper end to said frame assembly adjacent said upper end thereof; and brake means carried vertically along said frame assembly and terminating at one end adjacent said wheel means and for engagement therewith when said brake means are applied and terminating in a hand-operable position adjacent said upper end of said frame assembly.
