Abstract
A toggle latch having three linkage means, the first and third linkage means being pivotally connected to a frame and the second linkage means being pivotally connected between the first and third linkage means. The first linkage means having a pivot slidably restrained within a frame aperture for moving between a first position when the toggle latch assembly is secured and a second position where the toggle latch assembly is opened. In one embodiment, a forth linkage means is positioned between the frame and the slidable pivot of the first linkage means in order to decrease the frictional loading on the slidable pivot.
