Abstract
Abstract A wheelchair carrier has a generally U-shaped frame work constituted by a pair of upright struts whose upper ends are coupled to a relatively low-slung cross brace. Projecting rearwardly is a swing arm pivotally coupled to one side of the frame work and a holding arm fixed to the other side of the frame work. With the swing arm rotated out of the way to a retracted position, a wheelchair may be assembled onto the carrier by first looping or placing a front corner section of the wheelchair over the holding arm and using it as a pivot to swing the wheelchair upwardly with a lifting action. Once the wheelchair is urged to the desired position, then the swing arm is rotated back to underlie and support the wheelchair handle grips or back rest section. The swing arm may be set in place by a detent and locking knob arrangement.

Claim 1
Independent Claim
181 words
An article carrier attachable to a bumper of a vehicle, comprising: a. a generally U-shape frame work having a pair of laterally spaced struts and a cross brace coupled to the upper ends of the struts; b. clamping assemblies secured to corresponding struts for removably securing the U-shaped frame work to a vehicle bumper; c. a holding arm extending rearwardly from and being coupled to one side of the U-shaped framework, the holding arm having a hook; d. a pivot element extending rearwardly from and coupled to the other side of the U-shaped framework; e. a swing arm with a hook arranged offset vertically from the holding arm, the swing arm being rotatably coupled to the pivot element for arcuate movement in a plane generally parallel to the plane of the framework, and, f. a detent coupled to the swing arm and pivot element and structured for allowing the swing arm to be locked at selected positions within its path of movement across the framework, wherein, an article may be disposed between and supported by the swing arm and holding arm.
