Abstract

A filter frame assembly is disclosed comprising a perimeter member surrounding a fluid aperture adapted to accommodate a fluid flow from an upstream direction to a downstream direction, the perimeter member comprising a perimeter upstream surface, a perimeter downstream surface, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface. A gasket carrier is attached to the perimeter member and comprises a carrier outer portion facing generally away from the fluid aperture and a first outer portion sealing member projecting from the carrier outer portion.

First claim

What is claimed is:

1. A filter assembly comprising:
a unitary perimeter member surrounding a fluid aperture adapted to accommodate a fluid flow from an upstream direction to a downstream direction, the perimeter member comprising a perimeter upstream surface extending inwardly toward the fluid aperture, a perimeter downstream surface extending inwardly toward the fluid aperture, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface;
a filter media spanning the fluid aperture, the filter media positioned between the perimeter upstream surface and the perimeter downstream surface with the perimeter upstream surface and the perimeter downstream surface covering at least a portion of the filter media; and
a gasket carrier attached to the perimeter outer surface and comprising a carrier outer portion facing generally away from the fluid aperture and a first outer portion sealing member projecting from the carrier outer portion.

2. The filter frame assembly of claim 1 wherein the gasket carrier further comprises a carrier upstream portion generally facing the upstream direction.

3. The filter frame assembly of claim 2 wherein the gasket carrier further comprises an upstream sealing member projecting from the carrier upstream portion.

4. The filter frame assembly of claim 1 wherein the gasket carrier further comprises a carrier downstream portion generally facing the downstream direction.

5. The filter frame assembly of claim 4 wherein the gasket carrier further comprises a downstream sealing member projecting from the carrier downstream portion.

6. The filter frame assembly of claim 1 wherein the gasket carrier comprises a carrier upstream portion generally facing the upstream direction and a carrier downstream portion generally facing the downstream direction, the carrier outer portion connecting the carrier upstream portion to the carrier downstream portion.

7. The filter frame assembly of claim 6 further comprising at least one of a downstream sealing member projecting from the carrier downstream portion or an upstream sealing member projecting from the carrier upstream portion.

8. The filter frame assembly of claim 7 comprising both a downstream sealing member projecting from the carrier downstream portion and an upstream sealing member projecting from the carrier upstream portion.

9. The filter frame assembly of claim 1 comprising a second outer portion sealing member projecting from the carrier outer portion, wherein the first outer portion sealing member is positioned more proximate the upstream direction than the second outer portion sealing member.

10. The filter frame assembly of claim 1 wherein the perimeter member comprises four members arranged in a rectangle.

11. The filter frame assembly of claim 10 wherein the gasket carrier comprises four portions, one portion being attached to each member of the perimeter member.

12. The filter frame assembly of claim 11 wherein the four portions of the gasket carrier are not connected to one another.

13. The filter frame assembly of claim 1 wherein the gasket carrier is attached to the perimeter member by an adhesive.

14. The filter frame assembly of claim 1 wherein the gasket carrier is attached to the perimeter member by a clip feature.

15. The filter frame assembly of claim 14 wherein the clip feature is integrally formed onto one of the gasket carrier or the perimeter member such that the clip feature slides over a clipping member on the other to secure the clip feature over the clipping member by friction.

16. The filter frame assembly of claim 15 wherein the gasket carrier is sufficiently resilient to bend to permit the clip feature to slide over the clipping member.

17. The filter frame assembly of claim 16 wherein the gasket carrier comprises the clip feature and the perimeter member comprises the clipping member.

18. The filter frame assembly of claim 1 wherein the gasket carrier is attached to the perimeter member by a snap feature.

19. The filter frame assembly of claim 18 wherein the snap feature comprises a recess on one of the perimeter member or the gasket carrier and a protrusion on the other to snap into the recess.

20. The filter frame assembly of claim 19 wherein the gasket carrier is sufficiently resilient to bend to permit the protrusion and the recess to snap together.

21. The filter frame assembly of claim 19 wherein the perimeter member comprises a recess and the gasket carrier comprises a protrusion.

22. The filter frame assembly of claim 21 wherein the perimeter member comprises a recess on each of the perimeter upstream surface and the perimeter downstream surface; and
wherein the gasket carrier comprises a protrusion projecting inwardly from the carrier upstream portion to snap into the recess on the perimeter upstream surface and a protrusion projecting inwardly from the carrier downstream portion to snap into the recess on the perimeter downstream surface.

23. The filter frame assembly of claim 1 wherein the gasket carrier is attached to the perimeter member by a press feature.

24. The filter frame assembly of claim 23 wherein the press feature comprises a reception channel on one of the perimeter member or the gasket carrier and a plug on the other to press into the reception channel.

25. The filter frame assembly of claim 24 wherein the perimeter member comprises a reception channel and the gasket carrier comprises a plug.

26. The filter frame assembly of claim 24 wherein plug comprises one or more retention features to cooperate with an inner wall of the reception channel to resist removal of the plug from the reception channel.

27. The filter frame assembly of claim 1 wherein the perimeter member defines a perimeter direction along the perimeter member, wherein the gasket carrier is attached to the perimeter member by a slide feature such that the gasket carrier slides onto the perimeter member along the perimeter direction.

28. The filter frame assembly of claim 27 wherein the slide feature comprises a slot on one of the perimeter member or the gasket carrier and a rail on the other to slide into the slot.

29. The filter frame assembly of claim 28 wherein the perimeter member comprises a slot and the gasket carrier comprises a rail.

30. The filter frame assembly of claim 28 wherein the slot and the rail cooperate in a dovetail configuration.

31. The filter frame assembly of claim 6 wherein the gasket carrier comprises independent first and second carrier portions, the first carrier portion comprising a carrier upstream portion and a portion of the carrier outer portion; the second carrier portion comprising a carrier downstream portion and the remaining portion of the carrier outer portion.

32. The filter frame assembly of claim 31 comprising both a downstream sealing member projecting outwardly from the carrier downstream portion and an upstream sealing member projecting outwardly from the carrier upstream portion.

33. The filter frame assembly of claim 31 comprising a second outer portion sealing member projecting from the carrier outer portion, wherein the first outer portion sealing member is positioned on the first carrier portion and the second outer portion sealing member is positioned on the
