Abstract: A door or window lock has a body which is securable to the door, window, or a surround for a door or window, and has at least two passages therethrough that extend angularly relative to one another. A locking bar is slidable axially in any one of the passages to adopt either an operative position or an inoperative position, and in the operative position a locking end portion of the bar protrudes a predetermined distance beyond an adjacent side of the body. The bar can adopt either of two operative positions for each passage and in each of those positions the locking end portion protrudes beyond a respective one of two opposite sides of the body. A key operated locking member is rotatably mounted on the body and can adopt a particular locking position for each of the passages. In the locking position for one passage, the locking member protrudes into a recess of the bar to hold the bar against movement in either direction from its operative position.

Abstract: A locking mechanism for a vault door having a plurality of independently negatable locks, each one coupled through its bolt to a respective pivoted locking arm. In the locking condition the arms are pivoted to block withdrawal of bars carried by the main boltstraps. Each lock bolt is connected to its arm by a rotatable control member having a lobe and an eccentric peg which engages in a slot in the respective arm. To negate a lock its bolt is thrown and a lever turned to rotate the respective control member. This places the lobe next to the lock case and pivots the locking arm into its unblocking position. If the door is left open with the boltwork withdrawn and unlocked unauthorized negation of a lock cannot take place because there is insufficient space to rotate the respective control member without the latter abutting the lock case.
