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.
Claims22
An exit device assembly for use with a door having a top, a bottom and a generally vertical surface, the exit device assembly comprising:
- an exit device configured to be mounted on the vertical 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;
- a cable for causing movement of the latch in response to movement of the manually movable member;
- and
- a slack removal mechanism connected to the cable;
- wherein the slack removal mechanism is operably connected with the manually movable member such that movement of the manually movable member causes movement of the slack removal mechanism in a first manner to actuate the latch;
- and
- wherein the slack removal mechanism is independently movable in a second manner distinct from the first manner to remove slack in the cable;
- wherein movement of the slack removal mechanism in the first manner comprises translation of the slack removal mechanism;
- and
- wherein movement of the slack removal mechanism in the second manner comprises rotation of a spool of the slack removal mechanism.
An exit device assembly for use with a door having a top, a bottom and a generally vertical surface, the exit device assembly comprising:
- an exit device configured to be mounted on the vertical 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 having an actuated state and a deactuated state;
- a cable connected between the manually movable member and the latch mechanism;
- and
- a slack removal mechanism connected with the cable, the slack removal mechanism having an adjustment motion in which the slack removal mechanism adjusts a slack in the cable, and an independent driving motion in which the slack removal mechanism moves with the cable;
- wherein the slack removal mechanism is operably connected with the manually movable member and is configured to move in the driving motion in response to movement of the manually movable member;
- and
- wherein the latch mechanism is configured to move between the actuated state and the deactuated state in response to the driving motion of the slack removal mechanism and the corresponding movement of the cable.
An exit device assembly, comprising:
- a manually movable pushbar;
- a slide member operably connected with the pushbar;
- a latch mechanism having an actuated state and a deactuated state;
- a cable connected between the latch mechanism and the slide member;
- and
- a slack removal mechanism comprising a spool, wherein the cable includes a portion that is wrapped around the spool, and wherein rotation of the spool in a first rotational direction increases a length of the portion that is wrapped around the spool, thereby removing slack from the cable;
- wherein the slide member is configured to translate the cable and the slack removal mechanism in response to movement of the pushbar;
- and
- wherein the latch mechanism is configured to move between the actuated state and the deactuated state in response to translation of the cable and the slack removal mechanism.
