Abstract

Apparatus for selectively locking and controllably releasing a panic exit door include a lock structure having a door locking position and a door release position and including a pair of vertical bars for locking the door at the top and bottom thereof. A manually actuable crash bar is located on one side of the door for actuating the lock, and a further manually actuable device for actuating the lock is located on the other side of the door. A remotely controllable device selectively blocks and releases the further manually actuable device, and a remote control selectively actuates the remotely controllable device.

Claims

1. Apparatus for selectively locking and controllably releasing a panic exit door, comprising in combination:

selectively actuable lock means on said door having a door locking position and a door release position, said lock means comprising means including a first vertical locking bar for selectively locking said door at the bottom thereof, means including a second vertical locking bar for selectively locking said door at the top thereof, and means coupled to said locking bars for biasing said first and seconD vertical locking bars away from one another into locking positions;

first manually actuable means coupled to said lock means for selectively applying actuating power to said lock means, said first manually actuable means comprising a panic exit crash bar and actuating means for moving said first and second vertical locking bars toward one another into door release positions upon actuation of said crash bar;

means for mounting said first manually actuable means on said door for access from one side of said door;

second manually actuable means selectively coupled to said lock means for selectively applying actuating power to said lock means;

means for mounting said second manually actuable means on said door for access from another side of said door;

remotely controllable means selectively coupled to said second manually actuable means for selectively blocking and permitting the application of actuating power by said second manually actuable means to said lock means, said remotely controllable means including means for permitting said application of actuating power in response to a remote control operation and means for automatically blocking said application of actuating power upon cessation of said remote control operation; and

remote control means connected to said controllable means for selectively effecting said remote control operation.

2. Apparatus as claimed in claim 1, wherein:

said second manually actuable means include coupling means permitting application of actuating power to said lock means by said first manually actuable means while said second manually actuable means are blocked by said remotely controllable means.

3. Apparatus as claimed in claim 2, including:

means coupled to said door for automatically closing said door; and

means coupled to said lock means for automatically actuating said lock means to said door locking position upon closure of said door.

4. Apparatus as claimed in claim 2, wherein:

said coupling means include a lost-motion coupling between said second manually actuable means and said vertical locking bar.

5. Apparatus as claimed in claim 1, wherein:

said second manually actuable means include a manually actuable member and power-transmitting means coupled between said manually actuable member and said lock means for actuating said lock means to said door release position upon manual actuation of said manually actuable member; and

said remotely controllable means include means operatively associated with said power-transmitting means for selectively freeing said power-transmitting means in response to a remote control operation and means for automatically blocking said power-transmitting means upon cessation of said remote control operation.

6. Apparatus as claimed in claim 1, wherein:

said remotely controllable means include an electrical actuator; and

said remote control means include means for electrically energizing said actuator.

7. Apparatus as claimed in claim 1, wherein:

said remotely controllable means include an electrical actuator; and

said remote control means include means incorporating a predetermined code, and means responsive to said code for electrically energizing said actuator.

8. Apparatus as claimed in claim 1, wherein:

said remote control means include means for delaying said automatic blocking of said actuating power for a predetermined period of time.

9. Apparatus as claimed in claim 8, wherein:

said remote control means include time delay means for delaying said automatic blocking of said actuating power for said predetermined period of time.

10. Apparatus as claimed in claim 1, wherein:

said remotely controllable means include an electrical actuator for selectively permitting said application of actuating power and time delay means coupled to said automatic blocking means for releasing said automatic blocking means only after expiration of a predetermined time delay.

11. Apparatus aS claimed in claim 1, wherein:

said remotely controllable means include an electrical actuator; and

said remote control means include a card key incorporating a predetermined code, and means responsive to said code on said card key for electrically energizing said actuator.

12. Apparatus as claimed in claim 11, wherein:

said remotely controllable means include an electrical actuator for selectively permitting said application of actuating power and time delay means coupled to said automatic blocking means for releasing said automatic blocking means only after expiration of a predetermined time delay.

13. Apparatus as claimed in claim 11, wherein:

said remote control means include means for delaying said automatic blocking of said actuating power for a predetermined period of time.

14. Apparatus as claimed in claim 13, wherein:

said remote control means include time delay means for delaying said automatic blocking of said actuating power for said predetermined period of time.
