<p>A lock for the locking of a sliding closure. The lock includes a housing (10) with a pair of hook shaped locking elements (11) which are mounted for counter-rotation within the housing. A handle (26) is mounted for rotation on the housing and is coupled to a gear wheel (23) which meshes with a pair of rack elements (30, 32) which are located for sliding movement in the housing (10). A projection (34) from each rack element (30, 32) engages in a curved slot (35) of the locking element (11). Consequently, rotation of the handle (26) results in a sliding movement of each of the racks (30, 32) which causes the locking elements to move between a firstposition where the locking elements are substantially retracted in the housing (10) and a second position where the locking elements can latchingly engage with a strike.</p> |
