ABSTRACT:
An amputee mobility device includes a wheeled frame, and seat with webbed pocket for receiving an amputated leg. The seat is adjustable height adjustable, as is the pocket for customizing to individuals. Adjustable handles allow amputees to move themselves, or allow a helper to push like a wheelchair. In one form, the frame includes front and rear articulated subframes. In another form, the wheeled frame forms an elongated rigid frame, with two fixed-axle wheels and two rear-located steerable wheels and one front-located steerable wheel. In another form, the frame includes two fixed-axle wheels and two steerable wheels arranged to function somewhat like a wheeled walking cane. Optional features include outriggers for leg protection, a foldable frame for compact storage and shipment, bicycle-like lockable hand brakes, a seat without aperture for supporting a lower leg extending horizontally, storage shelves, and cup holders.
