AI Technical Summary

Benefits of technology

"The present invention is a low profile roof vent that prevents water from entering the roof and attic. It includes a base tray and water shield that are bonded together to extend into the roof surface. The vent has a circuitous air path that allows air to flow through while preventing water from entering. The invention is easy to manufacture using injection molding techniques, which reduces costs. The technical effects of the invention are improved efficiency, prevention of water damage, and reduced manufacturing costs."

Problems solved by technology

Although there are low profile roof vents, these generally are difficult to assemble and have limited air flow.

Embodiment Construction

[0013]The vent 10 of the present invention includes a base 12 and a cover 14. The base includes a peripheral flange 16, a base tray 18 and a water shield member 20. The base tray includes a base tray 22 which includes a base 23, a back wall 24, and side walls 26 and 28. The base tray 18 is supported by corner supports 32 and 34 which extend upwardly to a peripheral ledge 36 in turn bonded to peripheral flange 16. A front edge 38 of the base 23 extends and is continuous with a lower flange 40. Side walls 26 and 28 extend from supports 32 and 34 to the ledge 36 and flange40.

[0014]As designed, the base tray 18 provides a rear air path 42 and side air paths 44 and 46, which permit air flow over the walls of the base pan 22 and, as is described hereinafter, out of the vent.

[0015]The water shield 20 which is formed separately from the base tray 18 member and is integral with flange 16. Flange 16 includes a top flange member 50 and side flange members 52 and 54. Further, there is a lower b...

Abstract

A low profile roof vent incorporates a base portion which includes a water collecting tray extending down from a peripheral flange and a water shield portion extending from the opening of the vent towards the base tray. The base tray leads to a forward edge of the vent allowing any water collecting in the base tray to flow out from the vent onto the roof surface. The vent further incorporates a vent cover coplanar with the peripheral flange of the base. This provides a vent which lies flush with the roof surface, improving the aesthetic appeal of the roof.

Description

BACKGROUND OF THE INVENTION[0001]Roof vents are designed to permit air flow from an attic space and prevent moisture accumulation in the attic. These vents provide two functions, they allow air in or out, and they prevent water from entering the opening.[0002]In order to prevent water entering through the vent opening, the roof vent generally extends above the roof line. This detracts from the appearance of the roof.[0003]Although there are low profile roof vents, these generally are difficult to assemble and have limited air flow.SUMMARY OF THE INVENTION[0004]The present invention is premised on the realization that an efficient, low profile roof vent includes a base tray which extends from the roof line into the roof with side and rear walls extending partially up from the tray, in combination with a water shield portion which has side walls that extend into the base tray. Spacing between the base tray walls and the water shield provides an air flow path. The base tray and water s...
