Abstract: A door locking system for attachment to an outwardly opening door which engages the door frame and which has a panic bar movable towards the door for disengaging the locking system. The locking device includes an outer sleeve fixedly mounted to the interior surface of the door and extending over one side of the door frame. An inner sleeve is provided within the outer sleeve which is pulled outwardly to a door frame engagement position, wherein the inner sleeve extends over the other side of the door frame to prevent the door from being opened. Movement of the panic bar towards the door causes the inner sleeve to retract into the outer sleeve, thereby allowing the door to be opened. A reset system is provided for automatically resetting the lock when the door is closed.

Abstract: A door locking system for attachment to an outwardly opening door which engages the door frame and which has a panic bar movable towards the door for disengaging the locking system. The locking device includes an outer sleeve fixedly mounted to the interior surface of the door and extending over one side of the door frame. An inner sleeve is provided within the outer sleeve which is pulled against a spring to a door frame engagement position, wherein inner sleeve extends over the other side of the door frame to prevent the door from being opened. A catch on the panic bar retains the inner sleeve in the engagement position, and movement of the panic bar towards the door causes the inner sleeve to retract into the outer sleeve, thereby allowing the door to be opened.
