Abstract

Abstract A vehicle attached wheelchair support is formed by a stationary frame mounted on a horizontal base tube and a lateral pivotally connected frame joined to the base tube permitting movement of one end portion toward and away from the surface of the earth. The base tube is telescopically joined to a socket forming member secured to an end surface of a vehicle. The pivoting frame forms a space receiving the large wheels and major portion of a wheelchair in supporting relation. A handle on the pivoting frame enables the tilting frame to be lifted to a stationary frame locked position or moved toward the surface of the earth for loading and unloading the wheelchair.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 218 words
In a wheelchair support for connection with an automotive vehicle bumper or other surface for transporting a folded wheelchair of the type having large rear wheels, the improvement comprising: a base tube secured to and projecting longitudinally rearward from the vehicle adjacent the horizontal plane of the bumper; a generally upright inverted U-shaped frame having legs rigidly secured to respective end portions of said base tube; open framework means including spaced-apart vertically disposed side members projecting laterally of said base tube and pivotally connected at one end portion between the legs of said U-shaped frame for vertical pivoting movement of their laterally remote end portions from a downward earth surface contacting wheelchair loading and unloading position to an upward wheelchair supporting position, and a cross rod extending between the respective end portion of said side members adjacent their lower limit and defining, in combination with said side members, a framework vertical opening having a length greater than the radius and less than the diameter of a wheelchair large wheels for subtending an arc of the periphery of the large wheels when supported therein and lowering the wheelchair center of gravity toward the plane of the framework opening; and, spring urged latch means for securing said framework means to said U-shaped frame in a wheelchair lifted and supported position.
Claim 2
Dependent Claim 218 words

Claim 3
Dependent Claim 9 words
The combination according to claim 1 and further including:
Claim 4
Dependent Claim 48 words
handle means connected with said framework means for moving its lateral end portion toward and away from the surface of the earth and rolling the large wheels of a folded wheelchair into and out of the framework means vertical opening when disposed adjacent the surface of the earth.
Claim 5
Dependent Claim 48 words
handle means connected with said framework means for moving its lateral end portion toward and away from the surface of the earth and rolling the large wheels of a folded wheelchair into and out of the framework means vertical opening when disposed adjacent the surface of the earth.
