Abstract

A frame assembly for an air distribution system includes a damper assembly, a louver assembly, and a screen frame. Air flows through the damper assembly and the louver assembly, where the damper assembly terminates in a first flange and the louver terminates in a second flange. The first flange and the second flange are coupled to one another about a screen frame such that the screen frame is captured by abutting the first flange and the second flange.

First claim

The invention claimed is:

1. A frame assembly for an air distribution system, comprising:
a damper assembly through which air flows and which terminates in a first flange; and
a louver assembly through which air flows and which terminates in a second flange, wherein the first flange and the second flange are coupled to one another about a screen frame such that the screen frame is captured by abutting the first flange and the second flange.

2. The frame assembly of claim 1 , wherein the screen frame comprises a clip portion configured to capture a distal end of the first flange and wherein the screen frame comprises a gasket portion configured to abut against the second flange.

3. The frame assembly of claim 2 , wherein the screen frame comprises a dual durometer.

4. The frame assembly of claim 3 , wherein the gasket portion comprises a first material of the dual durometer, and the clip portion comprises a second material of the dual durometer.

5. The frame assembly of claim 4 , wherein the second material is softer than the first material.

6. The frame assembly of claim 2 , wherein the clip portion comprises a first length, a second length extending transversely from the first length, a third length extending transversely from the second length, and a fourth length extending transversely from the third length, and wherein the first length, the second length, the third length, and the fourth length capture a profile of the distal end of the first flange.

7. The frame assembly of claim 1 , wherein the first flange comprises a clip portion configured to capture a distal end of the screen frame.

8. The frame assembly of claim 1 , wherein the second flange comprises a clip portion configured to capture a distal end of the screen frame.

9. The frame assembly of claim 1 , further comprising caulk, adhesive, foam, or any combination thereof applied between the screen frame and the second flange.

10. The frame assembly of claim 1 , wherein the screen frame comprises a leg configured to capture a screen between the screen frame and the second flange.

11. The frame assembly of claim 10 , wherein the screen frame comprises an adhesive layer disposed thereon coupling the screen to the screen frame.

12. The frame assembly of claim 1 , comprising a fastener extending through the first flange, the second flange, and the screen frame, wherein the fastener imparts a compressive force to couple the first flange and the second flange to one another and capture the screen frame.

13. A frame assembly for ductwork, comprising:
a damper comprising a damper blade coupled to a damper frame;
a louver comprising a louver blade coupled to a louver frame;
a screen frame disposed between the damper frame and the louver frame, wherein the screen frame is configured to capture a portion of the damper frame, and wherein the screen frame is configured to abut the louver frame; and
a screen disposed between the damper frame and the louver frame, wherein the screen is coupled to the screen frame.

14. The frame assembly of claim 13 , wherein the screen frame comprises a clip portion configured to capture a distal end of a flange of the damper frame.

15. The frame assembly of claim 13 , wherein the screen frame comprises a gasket portion configured to abut against a flange of the louver frame.

16. The frame assembly of claim 13 , wherein the screen frame comprises a leg configured to abut the screen against the louver frame.

17. The frame assembly of claim 13 , further comprising a fastener configured to couple the damper frame, the louver frame, the screen frame, and the screen to one another.

18. The frame assembly of claim 13 , wherein the damper frame comprises a first damper frame flange and a second damper frame flange, wherein the louver frame comprises a first louver frame flange and a second louver frame flange, wherein the screen frame is a first screen frame configured to capture the first damper frame flange and to abut the first louver frame flange, and wherein the frame assembly comprises a second screen frame configured to capture the second damper frame flange and to abut the second louver frame flange.

19. The frame assembly of claim 13 , wherein the frame assembly is configured to receive an air flow, wherein the damper is disposed downstream of the screen relative to a direction of the air flow, and wherein the screen is disposed downstream of the louver relative to the direction of the air flow.

20. The frame assembly of claim 13 , wherein a position of the damper blade is adjustable within the damper.
