ABSTRACT:
A clamping mechanism for clamping an object to a structural member. The clamping mechanism is particularly adapted for clamping a wheelchair wheel to a loading rack of a wheelchair loader. The clamping mechanism comprises a mounting bracket used for attachment to the structure, such as the wheelchair loading rack, and has a pivot pin fixedly attached thereto. Pivotally mounted with respect to the pivot pin is a handle assembly including a hollow handle with a spring biased actuation plate positioned therein. An actuation button is attached to the plate. The pivot pin extends through a transverse hole in the handle and has a key portion which lockably engages a keyway in the actuation plate. By depressing the actuation button, the keyway in the plate is moved with respect to the key on the pivot pin to an unlocked position so that the handle assembly may be pivoted. A clamp assembly is pivotally attached to the mounting bracket and interconnected with the handle by a pair of links such that as the handle is pivoted between locked and unlocked positions, the clamp assembly is moved from a clamping position to an unclamped position. A resilient ring is disposed between a head portion of the pivot pin and the handle assembly to act as a friction clutch for preventing undesired movement of the handle assembly. A wheelchair loading rack utilizing the clamping mechanism is also disclosed.
