Abstract

An air control damper, comprising a shaft coupled to a frame. A first full blade coupled to the axel and disposed within the frame. A rocker assembly coupled to the first full blade. A first rod coupled to the rocker assembly. A cross-link assembly coupled to the first rod. A half blade coupled to the cross-link assembly and disposed on a first shaft within the frame, wherein the half blade is configured to provide a blade stop for the first full blade in a closed position.

Claims

1. An air control damper, comprising:

an axel coupled to a frame;

a first full blade coupled to the axel and disposed within the frame;

a rocker assembly coupled to the first full blade;

a first rod coupled to the first rocker assembly;

a first cross-link assembly coupled to the first rod; and

a half blade coupled to the first cross-link assembly and disposed on a first shaft within the frame, wherein the half blade is configured to provide a blade stop for the first full blade in a closed position.

2. The air control damper of claim 1 further comprising a second rod coupled to the rocker assembly.

3. The air control damper of claim 2 further comprising a second cross-link assembly coupled to the second rod.

4. The air control damper of claim 3 further comprising a second full blade coupled to the second cross-link assembly and disposed on a second shaft within the frame.

5. The air control damper of claim 1 wherein the first full blade further comprises a plurality of slots, each configured to hold a seal.

6. The air control damper of claim 1 wherein the first full blade further comprises a plurality of protrusions, each configured to hold a foam material disposed within the first full blade.

7. The air control damper of claim 1 wherein the half blade further comprises a slot configured to hold a seal.

8. The air control damper of claim 1 wherein the half blade further comprises a plurality of protrusions, each configured to hold a foam material disposed within the half blade.

9. The air control damper of claim 1 wherein the frame further comprises a plurality of slots, each configured to hold a seal.

10. A method of manufacturing an air control damper that has a shaft coupled to a frame, a first full blade coupled to the axel and disposed within the frame, a rocker assembly coupled to the first full blade, a first rod coupled to the rocker assembly, a first cross-link assembly coupled to the first rod, a half blade coupled to the first cross-link assembly and disposed on a first shaft within the frame, wherein the half blade is configured to provide a blade stop for the first full blade in a closed position, a second rod coupled to the rocker assembly, a second cross-link assembly coupled to the second rod, a second full blade coupled to the second cross-link assembly and disposed on a second shaft within the frame, wherein the first full blade further comprises a plurality of slots, each configured to hold a seal, wherein the first full blade further comprises a plurality of protrusions, each configured to hold a foam material disposed within the first full blade, wherein the half blade further comprises a slot configured to hold a seal, wherein the half blade further comprises a plurality of protrusions, each configured to hold a foam material disposed within the half blade, and wherein the frame further comprises a plurality of slots, each configured to hold a seal, the method comprising:

coupling an axel to a frame;

coupling a first full blade to the axel and disposing the first full blade within the frame;

coupling a rocker assembly to the first full blade;

coupling a first rod to the rocker assembly;

coupling a first cross-link assembly to the first rod;

coupling a half blade to the first cross-link assembly and disposing the half blade on a first shaft within the frame;

coupling a second rod to the rocker assembly;

coupling a second cross-link assembly to the second rod;

coupling a second full blade to the second cross-link assembly and disposing the second full blade on a second shaft within the frame;

forming a plurality of slots in the first full blade, each configured to hold a seal;

forming a plurality of protrusions in the first full blade, each configured to hold a foam material disposed within the first full blade;

forming a slot in the half blade further to hold a seal;

forming a plurality of protrusions in the half blade to hold a foam material disposed within the half blade; and

forming a plurality of slots in the frame, each configured to hold a seal, wherein the half blade is configured to provide a blade stop for the first full blade in a closed position, and wherein the steps can be performed in any suitable order.

11. A method of manufacturing an air control damper, comprising:

coupling an axel to a frame;

coupling a first full blade to the axel and disposing the first full blade within the frame;

coupling a rocker assembly to the first full blade;

coupling a first rod to the rocker assembly;

coupling a first cross-link assembly to the first rod; and

coupling a half blade to the first cross-link assembly and disposing the half blade on a first shaft within the frame, wherein the half blade is configured to provide a blade stop for the first full blade in a closed position, and wherein the steps can be performed in any suitable order.

12. The method of claim 11 further comprising coupling a second rod to the rocker assembly.

13. The method of claim 12 further comprising coupling a second cross-link assembly to the second rod.

14. The method of claim 13 further comprising coupling a second full blade to the second cross-link assembly and disposing the second full blade on a second shaft within the frame.

15. The method of claim 11 further comprising forming a plurality of slots in the first full blade, each configured to hold a seal.

16. The method of claim 11 further comprising forming a plurality of protrusions in the first full blade, each configured to hold a foam material disposed within the first full blade.

17. The method of claim 11 further comprising forming a slot in the half blade further to hold a seal.

18. The method of claim 11 further comprising forming a plurality of protrusions in the half blade to hold a foam material disposed within the half blade.

19. The method of claim 11 further comprising forming a plurality of slots in the frame, each configured to hold a seal.
