Abstract
An exit device assembly for use in association with a door having a top, a bottom and a generally vertical surface. The exit door assembly includes an exit device configured to be mounted on the surface of the door, the exit device including a manually movable member, a latch mechanism configured to be mounted adjacent one of the top and the bottom of the door, the latch mechanism including a latch movable between a locking position and a non-locking position, and a non-rigid device for causing movement of the latch in response to movement of the manually movable member.
Claims21
An access control assembly configured for use with a door, the access control assembly comprising:
- a latch mechanism configured for mounting to the door;
- a manual actuator configured for mounting to the door;
- a slide member engaged with the manual actuator and configured to translate in response to actuation of the manual actuator;
- a slack removal assembly mounted to the slide member such that the slack removal assembly translates with the slide member in response to actuation of the manual actuator;
- and
- a cable connected between the latch mechanism and the slack removal assembly;
- wherein the slack removal assembly is operable to adjust an effective length of the cable;
- and
- wherein the cable is configured to actuate the latch mechanism in response to translation of the slack removal assembly.
An access control assembly configured for use with a door, the access control assembly comprising:
- a first latch mechanism configured for mounting to the door;
- a manual actuator configured for mounting to the door;
- a first flexible cable connected between the manual actuator and the first latch mechanism such that actuation of the manual actuator causes a corresponding actuation of the first latch mechanism via the first flexible cable;
- and
- a slack removal assembly coupled to the first flexible cable, the slack removal assembly comprising:
- a spool onto which a first portion of the first flexible cable is wound;
- and
- a worm screw engaged with the spool such that rotation of the worm screw causes a corresponding rotation of the spool, thereby adjusting a length of the first flexible cable that is wound onto the spool.
An access control assembly configured for use with a door, the access control assembly comprising:
- a manual actuator configured for mounting to the door;
- a first latch mechanism configured for mounting to the door;
- a second latch mechanism configured for mounting to the door;
- a first cable operably connected between the manual actuator and the first latch mechanism such that actuation of the manual actuator causes a corresponding actuation of the first latch mechanism;
- and
- a second cable operably connected between the first latch mechanism and the second latch mechanism;
- and
- wherein the first latch mechanism is configured to pull the second cable to thereby actuate the second latch mechanism when the first latch mechanism is actuated by the manual actuator via the first cable.
