| Abstract: |
An ambulator which can be mated to a wheeled frame to form a wheelchair is provided to enable a paraplegic to stand on the ambulator and be separated from the frame for maneuvering in confined spaces. The ambulator has power operated articulated linkage for raising the paraplegic out of and free of the frame to the standing position on the ambulator; the compact base of the ambulator containing a drive mechanism for moving the ambulator in any desired direction through controls conveniently located on an arm rest. When the ambulator is mated with the frame, the linkage is lowered to carry the paraplegic in the sitting position.

First Claim:
Show all 2 claims |
What is claimed is:
1. An independently maneuverable ambulator for supporting and moving a paraplegic, comprising:
- a self-propelled, maneuverable base;
- a framework of linkage mounted on the base for raising and lowering the paraplegic between a standing position and a sitting position;
- a seat carried on said linkage to be held in a horizontal position for seating the paraplegic when said linkage is lowered, and in a substantially vertical position for supporting the paraplegic when said linkage is raised;
- said linkage being articulated at substantially the knee and hip joints of the paraplegic to minimize relative movement between the surface of the seat and the paraplegic's clothing, and said linkage being telescopically adjustable to be tailored to the body dimensions of the paraplegic;
- a motor-driven erection mechanism for raising and lowering said linkage, said erection mechanism comprising reversible drive means pivotally mounted on said base and reciprocating means operatively coupled to the driven means at one end and pivotally connected to the framework linkage at the one end; and
- a knee restraint is mounted to said linkage to follow the movement of the legs during the raising and lowering movement.
