A latch device

摘要

A latch device for sliding and hung window systems. The latch device has a mounting base (15) with which a pair of counter-rotatable cam elements (11) are mounted. A lever cover (12) is slidingly mounted on the base (15). The lever cover (12) is coupled to the cam element (11) so that sliding movement of the lever cover (12) causes the cam elements to counter-rotate. Each cam element (11) has a cam portion (22) which is engageable through an opening (41) in a keeper (14) to latchingly engage behind a cam engagement surface (42) associated with the opening (41).
