Abstract

Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with pivotally nestable and extensible handles that are movable relative to the housing to effect latching and unlatching movements of a resilient foot that is movable by the handle between clamped and released engagement with a keeper, and that is movable with a latch arm between latched and unlatched positions. The lock-type embodiment has a locking mechanism that is mounted on the housing to selectively permit and prevent unlatching movements of the resilient latch member. The resulting arrangement provides sturdy latch and lock assemblies that employ a small number of relatively movable parts that can be assembled and serviced with ease.
