| Abstract: |
A rotatable stand-up wheelchair or invalid mobility device which includes a main drive chassis having front and rear wheels. A means for raising and lowering the seat and back portion of the wheelchair raises and lowers the invalid from a substantially seated position on the seat to a substantially standing position supported by a foot plate attached to the base of the wheelchair. Stability of the wheelchair device is maintained by two triangular wheel configurations intercepting at their apex. In operation, the invalid can move while standing in such a fashion as the foot plate may be lowered to a close proximity to the ground so that the invalids hand approximates the level of a hand height of a non-handicapped person. This simulated normal motion and enables direct contact with countertops and other work surfaces.

What is claimed is:
1. An invalid mobility device, comprising:
- a main drive chassis having front and rear wheels and a main chassis vertical axis of rotation;
- an ambulator assembly rotatably attached to said chassis including an invalid supporting means having a seat which is pivotally mounted to the ambulator assembly, a back portion pivotally mounted to said seat, and a footplate attached to the ambulator assembly for receiving the feet of the invalid, said ambulator assembly having an ambulator assembly vertical axis of rotation spaced from the main chassis vertical axis of rotation;
- means for raising and lowering the seat and back portion to thereby raise and lower the invalid from a substantially seated position on the seat to a substantially standing position supported by the footplate;
- means for clamping the invalid against the seat and back portion of the invalid supporting means attached to the mobility device for supporting the invalid in the mobility device;
- independent drive means connected with the wheels for driving and steering said mobility device;
- means attached to the mobility device within reach of the invalid for controlling the speed and direction of movement of the chassis and the ambulator assembly;
- rotation means for rotating the ambulator assembly around the ambulator assembly vertical axis of rotation, to place the invalid within easy reach of countertops and work surfaces so that the invalid may stand without a barrier between his body and a countertop or other surface; and
- at least one caster attached to the footplate so that the footplate may be supported on and movable over the ground by the at least one caster, so that the footplate may be lowered to a close proximity to the ground so that the invalid's hand reach is at a level to enable direct contact with countertops and other work surfaces.
