Lock mechanism

摘要

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 ( 27 and 28 ) 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.
