Abstract
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 Analysis
Total Claims: 15
Claim 1
Independent Claim
285 words
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.
Claim 2
Dependent Claim
285 words
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.
Claim 3
Dependent Claim
43 words
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.
Claim 4
Dependent Claim
