ABSTRACT:
A lock mechanism primarily intended for a sliding door or window application. The lock mechanism includes a lock body (10) with a lock beak (21) rotatably mounted therewith and biased by a bias element (23) to a first position. The lock beak (21) is co-operable with a hook (20) of a strike (13) upon the hook engaging in the body whereby the lock beak (21) rotates to a second position against the bias of biasing element (23). Operating members (27and28) within the lock body (10) are operable by external actuating elements such that the operating members can be independently operated to cause the lock beak (21) to move from said first position to said second position and one of the operating members to retain the lock beak in said first position.
