ABSTRACT:
A fastener to removably secure two panels consists of a spring-loaded toggle latch (catch unit) on one panel and a keeper plate (strike) with a keeper lip on the other panel. The toggle latch comprises a pivot bracket with a flat base plate and opposite upstanding side ears, a pivotable operating lever (handle) and a pivotable hasp member (draw bar) having a downwardly turned lip at its free end to engage the keeper lip. The three members of the toggle latch are solely joined by left and right single-turn coiled torsion springs which spring-load the hasp member. In one embodiment the flat base plate of the pivot bracket has two openings, each with a series of staggered indentations forming pairs of indentations, which indented pairs are differently spaced from the edge of its panel, to permit adjustable mounting of the pivot bracket on its panel.
