Abstract

A vent is disclosed that is particularly suited to use in ventilating attic spaces beneath a hip roof. The vent is configured to be installed along a hip of the roof overlying and covering a ventilation slot formed through the roof deck along the hip. The vent includes an elongated laterally flexible top panel from which baffle arrays depend. The baffle arrays are formed of a plurality of depending arcuately curved vanes that arc away from the vent. The vanes are aerodynamically shaped to redirect wind-blown rain and snow away from the vent and are configured to block the migration of rain and snow through the vent. A pair of spongy conformable filler strips is attached beneath the edge portions of the vent. The filler strips conform to the shapes of underlying shingles when the vent is installed to fill any gaps that otherwise might be formed between the vent and the shingles. A weather filter drapes over some of the baffle arrays to allow attic air to pass but prevent ingress of blown snowflakes and raindrops.

First claim

The invention claimed is:

1. A hip vent for a hip style roof for providing ventilation of a space below the roof, the hip vent comprising:
an elongated panel having a central portion, side portions terminating at side edges, an upper end, a lower end, and a bottom side;
at least one baffle array extending along each of the side portions of the panel, each baffle array comprising a plurality of vanes projecting away from the bottom side of the panel, the plurality of vanes being arranged along the bottom side of the panel between the central portion and a side edge of the panel and defining a ventilation path therethrough to permit air flow through the plurality of depending vanes toward the side edges of the panel;
wherein each of the vanes includes an outer surface facing an adjacent side edge of the panel and extending from a first terminal edge located nearer the central portion and the upper end of the panel to a second terminal edge located nearer an adjacent side edge and the lower end of the panel, with the second terminal edge of at least some of the vanes laterally overlapping the first terminal edge of an adjacent vane;
wherein at least some of the vanes comprise independent structures not connected to another structure depending from the bottom side of the panel;
wherein the outer surfaces of the vanes face outwardly toward the adjacent side edge of the panel and upwardly toward the upper end of the panel so that when the hip vent is installed along a hip of the roof with its upper end higher than its lower end, the vanes encounter and redirect rain and snow along the outer surfaces of the vanes and away from the central portion of the panel and toward the adjacent side edge of the panel;
a filler strip attached to and extending along at least a lower portion of each baffle array and away from the top panel, the filler strip configured to conform to uneven surfaces of shingles along the roof when the hip vent is installed on the roof; and
a plurality of barrier walls projecting from the bottom surface of the panel, the barrier walls extending substantially transversely relative to the panel and being interspersed among the outer and inner regions of the baffle arrays.

2. The hip vent claimed in claim 1 further comprising a weather barrier draped over inner regions of the baffle arrays, the weather barrier being air permeable but substantially impermeable to rain and snow.

3. The hip vent claimed in claim 2 wherein the weather barrier extends along opposed sides of the inner regions of the baffle arrays to form two air permeable barriers to rain and snow.

4. The hip vent claimed in claim 1 , wherein the filler strip comprises a conformable material adapted to conform to the roofing shingles and fill gaps between the roofing shingles and the baffles.

5. The hip vent claimed in claim 4 wherein the filler strip is made of entangled polymer fibers.

6. The hip vent claimed in claim 4 wherein the filler strip is made of a foamed material.
