ABSTRACT:
A locking system comprises a lock mechanism including a casing structure adapted to be mounted to one of a door and a door frame and having a front plate with an aperture therein; a latch bolt mounted with respect to the casing structure for movement between a first position wherein a portion thereof extends from the front plate of the casing structure for latching engagement with the other of the door and door frame, and a second, retracted position wherein the same portion thereof is held out of position for said latching engagement. A deadlock member is mounted to the casing for movement between a blocking position wherein the deadlock member will prevent movement of the latch bolt to the second, retracted position, and a non-blocking position wherein the latch bolt is free to move to the retracted position. An operating disc is rotatably mounted coaxially with the latch bolt and coupled to rotate the latch bolt through a lost motion type of connection. A control system is provided for effecting selective rotatable movement of the operating disc to move the latch bolt to the retracted position, with the initial rotation of the operating disc resulting in the movement of the deadlock member to the non-blocking position, and with the lost motion connection delaying movement of the latch bolt until the deadlock is moved from the blocking position.
