A walker is disclosed having two sets of handles positioned for rising from and lowering to a seated position in addition to serving as a walking aid. The walker comprises a frame having a front section comprising a pair of front vertical supports and a rigid cross-piece, and two side sections each comprising a rear vertical support having a load-bearing axis formed through a ground-engaging point, rigid connectors connecting the side sections to the front section, a first pair of handles positioned to support a user in a standing or walking position, and a second pair of handles positioned below and to the rear of the first set of handles to support a user in rising from or lowering to a seated position, in which the geometric centers of each of the second pair of handles is positioned to the rear of the load-bearing axis of each of the rear vertical supports.

We claim: 1. A walker, comprising: a frame having a front section comprising a pair of front vertical supports each having an upper end and a lower end, and a rigid cross-piece having a first and a second lateral end positioned between and attached at the lateral ends to the front vertical supports

We claim: 1. A walker, comprising: a frame having a front section comprising a pair of front vertical supports each having an upper end and a lower end, and a rigid cross-piece having a first and a second lateral end positioned between and attached at the lateral ends to the front vertical supports, and two side sections each comprising a rear vertical support having an upper end, a lower end, and a load-bearing axis formed through a ground-engaging point at the lower end of each rear vertical support, wherein each said side section is connected to the front section by a rigid connector, and wherein the front section and the two side sections define a region of space within the walker; a first pair of handles positioned to support a user in a standing or walking position, wherein said first pair of handles are attached to the frame at the upper end of each of the front vertical supports and extend rearward; and a second pair of handles positioned to support a user in rising from or lowering to a seated position, wherein the second pair of handles is positioned below and to the rear of the first set of handles and wherein the geometric centers of each of the second pair of handles is positioned to the rear of the load-bearing axis of each of the rear vertical supports to allow a load to be exerted at least partly outside of the region of space within the walker. 2. The walker of claim 1 further comprising a pair of pivot axes to allow pivotable movement of said side sections between a first position wherein said side sections are in an open position and a second position wherein said side sections are in a closed position. 3. The walker of claim 2 wherein the pivot axes are positioned along the front vertical supports. 4. The walker of claim 2 wherein the pivot axes are positioned at the lateral ends of the cross-piece. 5. The walker of claim 2 further comprising a pair of locking mechanisms wherein said locking mechanisms allow said side sections to be locked in either an open or closed position. 6. The walker of claim 1 wherein the frame comprises aluminum tubing. 7. The walker of claim 6 wherein said vertical supports each comprise at least two coaxial sections of tubing wherein said tubing sections allow for relative axial movement. 8. The walker of claim 7 wherein said vertical supports further comprise a locking mechanism wherein said locking mechanism restricts relative axial movement of said tubing sections. 9. The walker of claim 1 wherein said first pair of handles is adjustable relative to the upper end of said front vertical supports. 10. The walker of claim 1 wherein each of said second pair of handles is attached to the frame at the upper end of each of the rear vertical supports and extend rearward. 11. The walker of claim 10 wherein said second pair of handles is adjustable relative to said rear vertical supports. 12. The walker of claim 1 wherein each of said second pair of handles is integral with the frame. 13. The walker of claim 1 further comprising wheels attached at the lower ends of the front and/or rear vertical supports. 14. The walker of claim 13 further comprising at least one hand brake for controlling the rotational speed of the wheels. 15. The walker of claim 1 further comprising glides attached at the lower ends of the front and/or rear vertical supports. 16. The walker of claim 15 wherein said glides each comprise a stem portion for engagement with the lower end of the vertical support and a cap portion for engagement with a surface. 17. The walker of claim 1 further comprising a seat affixed to said frame, said seat being movable between a first position wherein the seat is generally positioned in a vertical position and a second position wherein the seat is generally horizontal to provide a seat for a user. 18. The walker of claim 1 further comprising at least one compartment attached to the frame for carrying personal items. 19. The walker of claim 1 wherein at least one of said front vertical supports is provided with an attachment point at the upper end of said vertical support adapted to receive a pole or tool. 20. A walker, comprising: a frame having a front section comprising a front vertical support having an upper end and a lower end, and two side sections each comprising a rear vertical support having an upper end, a lower end, and a load-bearing axis formed through a ground-engaging point at the lower end of each rear vertical support, wherein each said side section is connected to the front section by a rigid connector, and wherein the front section and the two side sections define a region of space within the walker; a first pair of handles positioned to support a user in a standing or walking position, wherein said first pair of handles are attached to the frame and extend rearward; and a second pair of handles positioned to support a user in rising from or lowering to a seated position, wherein the second pair of handles is positioned below and to the rear of the first set of handles and wherein the geometric centers of each of the second pair of handles is positioned to the rear of the load-bearing axis of each of the rear vertical supports to allow a load to be exerted at least partly outside of the region of space within the walker.
