ABSTRACT:
A quick release clamp for securing components having a recessed base to a support having spaced internally threaded bores, said clamp having a body portion, a head portion at the top thereof and an outwardly extending lip adjacent the bottom of said clamp for engaging the component recess. A central bore in the body and head portion carries a resilient insert which is slidable therein. An elongated screw is threaded through the insert and receivable in one of the internally threaded bores. Rotation of the clamp as the screw member is threaded into the support brings the lip into locking contact with the component recess and a cammed surface on the bottom of the body into frictional contact with the component. A second cam substantially similar in shape and orientation to the bottom cam is formed on the top of the head and serves to aid in the accurate positioning of the bottom cam.
