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.
Claims17
A door locking device for attachment to a door, the door being held within a door frame having first and second outer frame surfaces adjacent the door and spaced on opposite sides of the door from one another, the door being hinged proximate the second frame surface for swinging outwardly away from the door frame, the door locking device comprising:
- a mounting structure for attachment to the door;
- a support structure connected to said mounting structure;
- said support structure including a stationary extension portion extending over and spaced in front of said second outer frame surface when the door is closed;
- at least one restraining member connected to said support structure and movable from an restraining position extending over and spaced in front of the first outer frame surface, for restraining the door from outward movement from the door frame, to a retracted position, for allowing the door to move outwardly from the door frame;
- and
- a retraction structure movable from a first position to a second position;
- said retraction structure being connected to said at least one restraining member for selectively causing said restraining member to be maintained in said restraining position when said retraction structure is in said first position, such that upon a force being delivered to said retraction structure in a direction towards the door, said retraction structure moves to said second position and causes said at least one restraining member to move from said restraining position to said retracted position, thereby allowing the door to swing outwardly from the door frame.
A door locking device for attachment to a door, the door being held within a door frame having first and second outer frame surfaces adjacent the door and spaced on opposite sides of the door from one another, the door being hinged proximate the second frame surface for swinging outwardly away from the door frame, the door locking device comprising:
- a mounting structure for attachment to the door;
- a support structure connected to said mounting structure;
- said support structure including a support member attached to said mounting structure;
- said support structure including an extension portion extending over and spaced in front of said second outer frame surface when the door is closed;
- at least one restraining member carried by said support member for sliding movement relative to said support member;
- said restraining member being movable from a restraining position extending over and spaced in front of the first outer frame surface, for restraining the door from outward movement from the door frame, to a retracted position, for allowing the door to move outwardly from the door frame;
- and
- a pushbar connected to said at least one restraining member;
- said pushbar being movable in a substantially horizontal plane, upon a substantially horizontally force being delivered to said pushbar in a direction towards the door, for causing said restraining member to move from said restraining position to said retracted position, thereby allowing the door to swing outwardly from the door frame.
