Abstract
A self-clamping mechanism includes a first support surface and a clamping member in sliding contact with the first support surface. The clamping member has a first surface in confronting engagement with the first support surface, and a second surface for engaging the surface of an object to be clamped by the mechanism. The first and second surfaces of the clamping member are disposed at a predetermined angle, θ, such that when certain conditions are met, the object will remain clamped by the mechanism regardless of external forces applied to the object.
