Abstract

An exit device assembly for coupling to a door having a first side and second side. A first exit device may be coupled to the first side of the door. The first exit device may include a main tube extending from a first end to a second end and a first adjustment tube coupled to the first end of the main tube. The first adjustment tube may be axially adjustable relative to the main tube along a first adjustment axis. An actuator assembly may be supported within an interior of the main tube of the first exit device and may be moveable between a first position and a second position. A latchbolt may be coupled to the actuator assembly and may be moveable between a retracted position and an extended position in which the latchbolt engages a latch.

First claim

What is claimed is:

1 . An exit device for coupling to a door having a first side, comprising:
a main tube extending from a first end to a second end; a first adjustment tube coupled to the first end of the main tube, the first adjustment tube axially adjustable relative to the main tube along a first adjustment axis; an actuator assembly supported by the main tube, the actuator assembly including an actuator adapted to fixedly couple to the first side of the door; and a latchbolt coupled to the actuator assembly and moveable between a retracted position and an extended position in which an end of the latchbolt is spaced apart from a distal end of the first adjustment tube, the latchbolt configured to engage a latch.

2 . The exit device of claim 1 , wherein the main tube is moveable towards the first side of the door between a rest state and an actuated state.

3 . The exit device of claim 2 , wherein the actuator includes a distal end having a curvilinear surface, and the actuator assembly includes a carriage supporting a roller engaged with the curvilinear surface of the actuator, the roller engaging a first portion of the curvilinear surface when the main tube is in the rest state and the roller engaging a second portion of the curvilinear surface when the main tube is in the actuated state.

4 . The exit device of claim 3 , wherein the curvilinear surface is angled.

5 . The exit device of claim 2 , wherein the latchbolt is in the extended position when the main tube is in the rest state, and the latchbolt is in the retracted position when the main tube is in the actuated state.

6 . The exit device of claim 1 , wherein the first adjustment tube is axially adjustable relative to the main tube between an inserted position and an extended position.

7 . The exit device of claim 6 , wherein an end of the first adjustment tube opposite the distal end includes a plurality of engagement features configured to engage complementary engagement features of the first end of the main tube.

8 . The exit device of claim 1 , wherein the first adjustment tube is received within an interior of the first end of the main tube, the first adjustment tube axially adjustable relative to the main tube to vary an amount of overlap of the first end of the main tube and the first adjustment tube.

9 . The exit device of claim 1 , further comprising a second adjustment tube coupled to the second end of the main tube, the second adjustment tube axially adjustable relative to the main tube along a second adjustment axis.

10 . The exit device of claim 9 , wherein the second adjustment axis is perpendicular to the first adjustment axis.

11 . The exit device of claim 1 , wherein a portion of the actuator assembly is supported within an interior of the main tube.

12 . The exit device of claim 11 , wherein the portion of the actuator assembly includes a sleeve assembly, the sleeve assembly operatively coupled to the actuator.

13 . The exit device of claim 1 , wherein when the latchbolt is in the retracted position, the end of the latchbolt is at least partially housed within an interior of the first adjustment tube.

14 . The exit device of claim 1 , wherein the first end of the main tube is angled relative to the second end of the main tube.

15 . An actuator assembly for an actuatable exit device, comprising:
an actuator having a distal end with a curvilinear surface; a carriage supporting a roller on a pin, the roller engaging the curvilinear surface of the actuator, the carriage moveable along an axis in a first direction and a second direction opposite the first direction, the carriage moveable along the axis between a first position and second position; and a first biasing member supported by the carriage and providing a biasing force against the carriage in the first direction.

16 . The actuator assembly of claim 15 , wherein the actuator is moveable between a retracted position and an extended position.

17 . The actuator assembly of claim 16 , wherein when the actuator is in the retracted position, the carriage is in the first position, and when the actuator is in the extended position, the carriage is in the second position and the first biasing member is compressed.

18 . The actuator assembly of claim 15 , wherein the carriage is supported within a sleeve, the sleeve moveable in a third direction and a fourth direction opposite the third direction, the third and fourth directions perpendicular to the first and second directions.

19 . The actuator assembly of claim 18 , wherein when the sleeve is displaced in the third direction, the carriage is displaced in the second direction against the biasing force of the biasing member.

20 . The actuator assembly of claim 15 , further comprising a latchbolt coupled to the carriage.

21 . The actuator assembly of claim 20 , wherein the latchbolt is coupled to the carriage opposite the biasing member.

22 . An exit device assembly for coupling to a door having a first side opposite a second side, comprising:
a drive member positioned on the first side of the door and moveable between a first position and a second position; and an actuator positioned on the second side of the door and operatively coupled to the drive member through a circular aperture of the door, wherein the actuator is moveable between a retracted position corresponding to the drive member in the first position and an extended position corresponding to the drive member in the second position.

23 . The exit device assembly of claim 22 , further comprising a housing positioned on the first side of the door, the housing supporting the drive member.

24 . The exit device assembly of claim 23 , further comprising a lock core supported by the housing and drivingly coupled to the drive member to selectively transition the drive member from the first position to the second position.

25 . The exit device assembly of claim 24 , wherein the drive member comprises a cam.

26 . The exit device assembly of claim 24 , wherein the lock core is oriented perpendicular to the actuator.

27 . The exit device assembly of claim 23 , further comprising a bolt coupled to the actuator and extending through the aperture of the door, the bolt engageable by the drive member to transition the actuator from the retracted position to the extended position.

28 . The exit device assembly of claim 23 , further comprising a first exit device pivotally coupled to the second side of the door and operatively coupled to the actuator.

29 . The exit device assembly of claim 28 , further comprising a second exit device fixedly coupled to the first side of the door and the housing.

30 . The exit device assembly of claim 22 , further comprising:
a mounting member supporting the drive member and positioned adjacent the first side of the door; and an adapter supporting the actuator and positioned adjacent the second side of the door, the adapter coupled to the mounting member only through the aperture in the door.

31 . The exit device assembly of claim 30 , further comprising a post extending from the adapter through the aperture in the door, the post coupled to the mounting member.

32 . A method of installing an exit device assembly, comprising:
providing a door having a first sid
