Abstract

A door with an integrated exit device has an operational bar which at least partially extends across the door. The operational bar is located within a recess in the face of the door. The operational bar has at least one arm that extends into a channel, which is formed in cooperation with the recess. The door has a locking channel which extends along the vertical edge of the door. The locking channel is coupled to a vertical stile that is fixedly located on the vertical edge of the door. The locking channel and the vertical stile are pivotally coupled by a clip. A blocking member is located within the vertical stile. The operational bar has an actuator arm located within the door and within the vertical stile. As the operational bar is pushed inward, actuator arm pushes blocking member to an open position which also allows locking channel to pivot to an open position. If access is required from both sides of the door, a handle may be located outside of the door and coupled to the operational bar by a connection arm. The connection arm moves the operational bar in cooperation with movement of the handle.

Claims

1. A door assembly having a door with a door surface having a recess in the door and an exit assembly, said exit assembly comprising:

wherein said door has a channel, said channel having a front side and a bottom side, said channel coupled to the recess;

an operational bar located within the recess, said operational bar having a first position within said recess so that said operational bar is substantially flush with the door surface and a second position wherein said operational bar partially extends from said recess a distance from said first position;

an arm coupled to said operational bar, said arm having a first end and a second end, said first end is coupled to said operational bar, said second end extending entirely within said channel and supporting said operational bar; and

a latching mechanism coupled to said operational bar through said door, said latching mechanism upon movement of said operational bar into a first position from a second position moving said latching mechanism to an open position.

2. A door assembly as recited in claim 1 further comprising a connection pin coupled to the operational bar, a handle located on an opposite side of the door from the operational bar, said operational bar and said connection pin coupled together through a connection arm.

3. A door assembly as recited in claim 1 further comprising a retainer coupled to a locking channel.

4. A door assembly as recited in claim 1 wherein said second end comprises a pivot extension.

5. A door assembly as recited in claim 4 wherein said pivot extension is positioned adjacent to said bottom side or said front side.

6. A door assembly having a door with a door surface having a recess in the door and an exit assembly, said exit assembly comprising:

an operational bar located within the recess, said operational bar having a first position within said recess so that said operational bar is substantially flush with the door surface and a second position wherein said operational bar partially extends from said recess a distance from said first position;

a latching mechanism coupled to said operational bar through said door, said latching mechanism upon movement of said operational bar into a first position from a second position moving said latching mechanism to an open position; and

an actuator arm coupled to said operational bar, said actuator arm coupled to said latching mechanism, said actuator arm moving with said operational bar.

7. A door assembly as recited in claim 6 wherein said latching mechanism comprises a blocking member coupled to a pin.

8. A door assembly as recited in claim 7 wherein said actuator arm is operatively coupled to said blocking member.

9. A door assembly comprising:

a door with a recess between two door faces and a channel coupled to the recess, said channel and said recess entirely between said two door faces;

an exit assembly comprising;

an operational bar located at least partially within the recess, said operational bar having an open position within said recess wherein said operational bar is substantially flush with the door surface and a closed position wherein said operational bar partially extends from said recess a distance greater than in said first position, said operational bar having a support arm having a first end and a second end, said first end coupled to said operational bar, said second end located entirely within said recess and said channel for supporting said operational bar and positioning said operational bar relative to said recess; and

a latching mechanism coupled to said operational bar through said door, said latching mechanism upon movement of said operational bar into the open position from the closed position moving said latching mechanism to an open position.

10. A door assembly as recited in claim 9 further comprising an actuator arm coupled to said operational bar, said actuator arm coupled to said latching mechanism, said actuator arm moving with said operational bar.

11. A door assembly as recited in claim 10 wherein said latching mechanism comprises a locking channel having a locking channel arm, said locking channel arm engaging said actuator arm in an open position thereby holding said operational bar within said recess.

12. A door assembly as recited in claim 9 wherein said support arm has a first end and a second end, said first end coupled to said operational bar, said second end extending within said channel.

13. A door assembly as recited in claim 12 wherein said second end comprises a pivot extension.

14. A door assembly as recited in claim 13 wherein said pivot extension is positioned adjacent to one of said two door faces.

15. A door assembly as recited in claim 9 further comprising a connection pin coupled to the operational bar, a handle located on an opposite side of the door from the operational bar, said operational bar and said connection pin coupled together through a connection arm.

16. A door assembly comprising:

a door having a vertical edge, a pair of door faces and a recess and a channel located entirely between said pair of door faces;

a vertical stile coupled to said vertical edge;

a locking channel movably coupled to said vertical stile;

a blocking member located with said vertical stile, said blocking member movably coupled to said locking channel, said blocking member having a first position and a second position;

an operational bar having a support arm coupled thereto, said operational bar located at least partially within said recess and said arm extending into said channel, said operational bar having an open position within said recess so that said operational bar extends a minimal distance from said door face so that said operational bar is substantially flush with the door face and a closed position wherein said operational bar partially extends from said recess a distance greater than the minimal distance; and

an actuator arm coupled to said operational bar, and operatively coupled to said blocking member, said actuator arm moving said blocking member from a first position to a second position when said operational bar is moved into said recess into said open position.

17. A door assembly as recited in claim 16 wherein said locking channel has a locking channel arm, said locking channel arm engaging said actuator arm in an open position to hold said operational bar within said recess.

18. A door assembly as recited in claim 16 further comprising a retainer coupled to said stile.

19. A door assembly as recited in claim 18 releasing said blocking member from a second position to a first position upon contact with a door frame.

20. A door assembly as recited in claim 18 further comprising a guide block coupling said retainer within said stile.
