ABSTRACT:
A draw latch is provided, of the over-center type, in which the latch has a base, a lever and a catch. The base and lever are pivotally connected to each other, and the catch and lever are pivotally connected to each other. The catch preferably has a lip or hook at its end, for engagement with a member that is to be drawn toward engagement with another member upon which the base is mounted, for drawing those members together, as the lever is moved from an open position to a closed position, through which movements the over-center motion is effected. Dimples or detents are used to provide a resistance to relative motion between the base and the lever on the one hand, and the lever and the catch on the other, through most of the range of their relative movements, but the detents become aligned or nested in one position for assembly of the components under non-frictional conditions, with the detents effecting a spring-like function upon legs of the lever.
