ABSTRACT:
A door latch mechanism mounts on a door for selectively engaging a door strike. A latch bolt moves along a line of action to disengage the strike and allow the door to be opened. A dead lock prevents unwanted opening of the door and includes a blocking element to prevent movement of the latch bolt along its line of action. A release enables the latch bolt to move along its line of action and includes a bell crank for displacing the blocking element whereby the latch bolt can disengage the strike.
