Abstract
A self adjusting toggle clamp includes a mounting body, mounting apparatus carried by the mounting body and a clamping link movably attached to the mounting body. An actuating lever having a link element is pivotally coupled to the clamping link and movably coupled to the mounting body by a self adjusting toggle mechanism. The self adjusting toggle mechanism includes a guide carried by the mounting body, a locking element carried by the guide for reciprocal and canting movement, an element pivotally coupled to the link element, and a cam element pivotally coupled to the element and pivotally coupled to the locking element. The cam element is movable between a first condition permitting the locking element to reciprocate along the guide and a second condition bearing against the guide and canting the locking element into frictional engagement with the guide.
