ABSTRACT:
This invention relates to walking aids in general, and more specifically to a wheelchair structure, which is adapted to be used in the normal manner, but which is modified in such a way that it will serve the dual function of walking aid, by incorporation into the standard wheelchair design, of a braking mechanism mounted on a support surface of the wheelchair, which is normally gripped by someone other than the occupant of the chair, and further by the provision of a weighted element which changes the normal center of gravity of the wheel chair to improve its stability in the walking aid mode.
