Abstract

An exit device comprises an inner door handle adapted to be mounted to a door for movement relative to the door from a first position to a second position. A pair of brackets are adapted to be operatively connected between the respective ends of a horizontal portion and a vertical portion of the door handle. Each bracket comprises a first bracket member secured to the door handle, a second bracket member adapted to be secured to the door, and a pin for joining the first bracket member and the second bracket member for rotation about an axis through the pin. The first bracket member and the second bracket member pivot relative to one another when the door handle moves between the first position and the second position.

First claim

We claim:

1. An exit device for use with a door, the exit device comprising:
a door handle adapted to be mounted to an interior of the door for pivoting movement toward and away from the door from a first position to a second position, the door handle when mounted to the door includes a horizontal component extending horizontally and a vertical component extending vertically; and
a pair of brackets, one bracket adapted to be operatively connected adjacent a horizontal end of the horizontal components between the horizontal component and the door and another bracket adapted to be operatively connected adjacent a vertical end of the vertical component between the vertical component and the door, each of the pair of brackets comprising:
a first bracket member secured to the door handle,
a second bracket member adapted to be secured to the door, and
a pin for joining the first bracket member and the second bracket member for rotation about an axis through the pin,
wherein the first bracket member and the second bracket member pivot relative to one another around the pin when the door handle moves between the first position and the second position.

2. The exit device as recited in claim 1 , wherein the axis of rotation of the first bracket member relative to the second bracket member around the pin is parallel to surface of the door to which the second bracket member is secured.

3. The exit device as recited in claim 1 , wherein the axis of rotation of the first bracket member relative to the second bracket member around the pin is perpendicular to a longitudinal axis of the door to which the second bracket member is secured.

4. The exit device as recited in claim 1 , further comprising a latch bolt disposed at one end of the door handle adjacent an edge of the door and movable relative to the door handle between a projected position extending outwardly of the door handle for latching the door in a closed position and a retracted position where the latch bolt is inside the door handle for allowing the door to be opened.

5. The exit device as recited in claim 4 , further comprising a retractor element disposed in the door handle for substantially rectilinear movement relative to the door handle from a first position to a second position in a path along a longitudinal axis of the door handle, the retractor element operatively connected between the door handle and the latch bolt, the retractor element moving toward the second position of the retractor element and the latch bolt moving toward the retracted position in response to movement of the door handle toward the second position of the door handle.

6. The exit device as recited in claim 5 , further comprising a spring associated with the retractor element for biasing the latch bolt to the projected position, wherein movement of the door handle toward the second position of the door handle moves the latch bolt from the projected position to the retracted position of the latch bolt for loading the spring.

7. The exit device as recited in claim 4 , wherein a distal end of the latch bolt has a planar outer surface for engaging a strike when the door is in the closed position.

8. The exit device as recited in claim 7 , wherein the planar outer surface of the latch bolt terminates in beveled edges.

9. The exit device as recited in claim 4 , wherein a distal tip of the latch bolt is rounded.

10. The exit device as recited in claim 4 , wherein a distal end of the latch bolt has a curved inner surface for engaging a strike during closing of the door.

11. The exit device as recited in claim 10 , wherein the curved inner surface of the latch bolt has a radius of curvature of from about 0.5 inches to about 2.0 inches.

12. The exit device as recited in claim 1 , wherein a length of the vertical component of the door handle is defined by a vertical distance from the horizontal component of the door handle to a top edge of the door.

13. The exit device as recited in claim 1 , wherein a length of the horizontal component of the door handle is defined by a horizontal distance from the vertical component of the door handle to adjacent a hinged edge of the door.

14. The exit device as recited in claim 1 , further comprising a fastener passing through an opening in the door for securing to the door the second bracket member associated with an end of the horizontal component of the door handle, and a c-shaped bushing adapted to be disposed in the opening in the door for positioning the fastener.

15. The exit device as recited in claim 1 , further comprising
a lock mechanism adapted to be mounted to an outer surface of the door, the lock mechanism including two elongated projections passing through an opening in the door for operative connection to a latch mechanism in the door handle, and
a bushing comprising a pair of conjoined circular members adapted to be disposed in the opening in the door, each circular member defining an opening for receiving a projection.

16. The exit device as recited in claim 15 , wherein the pair of conjoined circular members are vertically aligned in the door.

17. The exit device as recited in claim 1 , wherein the first bracket member and the second bracket member comprise arcing surfaces to allow for pivoting motion of the first bracket member and the second bracket member with respect to each other.

18. The exit device as recited in claim 17 , wherein one of the first bracket member or the second bracket member comprise a bifurcated end with legs each having an arcing surface, and wherein another of the first bracket member or the second bracket member comprise a boss having an arcing surface.

19. An exit device for use with a door, the exit device comprising:
a door handle adapted to be mounted to an interior of the door for pivoting movement toward and away from the door from a first position to a second position, the door handle when mounted to the door includes a horizontal component extending horizontally and a vertical component extending vertically; and
a first pivot bracket adapted to be operatively connected adjacent to an end of either the horizontal component or the vertical component between the door handle and the door, the first pivot bracket comprising:
a first bracket member secured to the door handle,
a second bracket member adapted to be secured to the door, and
a pin for joining the first bracket member and the second bracket member for rotation about an axis through the pin,
wherein the first bracket member and the second bracket member comprise arcing surfaces to allow for pivoting motion of the first bracket member and the second bracket member with respect to each other; and

a second bracket adapted to be operatively connected adjacent to the end of either the horizontal component or the vertical component opposite the first pivot bracket;
wherein the first bracket member and the second bracket member pivot relative to one another around the pin when the door handle moves between the first position and the second position.

20. An exit device for use with a door, the exit device comprising:
a door handle adapted to be mounted to an interior of the door for pivoting movement toward and away from the door from a first position to a second position, the door handle when mounted to the door includes a horizontal component extending horizontally and a vertical component extending vertically; and
a first bracket adapted to be operatively connected adjacent to an end of the horizontal component and a second bracket adapted to be opera
