ABSTRACT:
A hinged panel, mounted in a frame, has a latch comprising a toggle mechanism having a first link connected to the panel by a first pivot pin and a second link connected at one end to the first link by a second pivot pin. At its end opposite to the second pivot pin, the second link has an open-ended slot for receiving a third pivot pin which is mounted on the frame. A resilient retention lever is pivotally mounted on the second link and has a hook-like formation adapted to engage with the third pivot pin to retain it in the slot. At least one part of the periphery of the third pivot pin is flattened for that part of its length which is engaged by the hook-like formation. The retention lever is so arranged that the hook-like formation can disengage from the third pivot pin only by traversing the flattened surface.
