| Abstract: |
A powered walker apparatus includes a frame assembly defining a central space for containing an operator in a standing position. A mechanism is included for selectively moving the apparatus over a ground surface. A gate is provided for closing an entryway into the central space and is adapted to define the front surface of the apparatus when in a closed position. Finally, a seat assembly arrangement is provided having a seat member movable between a substantially horizontal position within the central space wherein the operator is maintained in a sitting position and a substantially vertical position wherein the operator is maintained in a standing position within such central space.

We claim:
1. A powered walker apparatus arranged to permit an operator to readily move between a fully seated position and a fully upright position therewithin, said walker apparatus comprising:
- frame assembly means having a base portion and spaced, vertical side portions projecting upwardly from said base portion to define a space therebetween for receiving an operator's body and to further define a front entryway to permit ingress to and egress from said space by said operator;
- means affixed to said base portion to provide foot support for said operator when in an upright, standing position within said apparatus;
- wheel means connected to said base portion for supporting said frame assembly means above a ground surface for movement therealong, said wheel means including at least one powered wheel member for moving said apparatus over said ground surface;
- means for providing power to said wheel means;
- means interconnecting said power means and said wheel means to permit said operator to control the movement of said wheel means and to thereby control the movement of said apparatus along said ground surface;
- gate means adapted to selectively extend across said entryway to provide a closure mechanism when said operator is in said apparatus;
- seat assembly means for supporting an operator when in a seated position within said apparatus as well as supporting said operator when in said upright position, said seat assembly means including a seat member and seat control means for selectively moving said seat member between a substantially horizontal position for carrying said operator in said seated position within said apparatus and a substantially vertical position for supporting said operator when said operator is in said upright position within said apparatus; and
- said seat control means including a seat control arm assembly for moving said seat member between a first rearward horizontal position disposed substantially entirely within the space defined by said vertical side portions and a second forward horizontal position wherein said seat member projects substantially outwardly through said front entryway to permit an operator easy access to said seat member exterior to said apparatus for transfer thereto or therefrom, the movement of said seat member from said second to said first horizontal position placing the operator fully within said apparatus.
