Abstract
Abstract A wheelchair support is attached to and extends from the bumper of an automobile and may be swung upwardly out of the way when not in use. A support frame for confining the wheels comprises members which define wheel recesses on opposite sides of an intermediate member, which carries an adjustable retaining member. The frame is supported on pivoted arms attached to a mounting frame having adjustable clamps which fit on and tighten to a conventional automobile bumper. A collapsed wheelchair is tilted upwards to place the large wheels in the well. Downward rotation of the wheelchair in the support frame causes the wheelchair frame to engage the retainer which secures the wheelchair in place.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
236 words
In a wheelchair support for attachment to an automobile bumper or other surface for supporting a folded wheelchair of the type including large rear wheels and a bottom frame having a backward projecting portion: a. a wheelchair carrying frame comprising opposed side frame members defining a space receiving therein the large, vertically disposed wheels of said folded wheelchair with the periphery of the wheels partly below said carrying frame resting in the space defined by and on the opposed side frame members and with the projecting portion of the wheelchair bottom frame within the confines of said carrying frame, b. means on said carrying frame for attaching and supporting said carrying frame on the bumper or the surface in horizontally extended carrying position, c. a retainer support member on said carrying frame and a retainer member on said retainer support member, said retainer member being engaged from beneath by the wheelchair bottom frame when said wheels are in said space and the projecting portion of the wheelchair frame is projected and rotated within said space thereby preventing the movement of the lower frame in vertical or rotational direction about the engagement of the rear wheels with the side members which define the space, whereby a person without the use of his legs may insert the wheelchair in place on the carrying frame and lock the wheelchair wheel to prevent relative rotation between wheelchair frame and wheel.
