Problems solved by technology

However, unprotected openings of roof vents may allow undesired entry of water into the house, such as into the attic, during extreme weather conditions.
Although this approach involves a moving part, the disclosure does not indicate what maintenance is required to maintain the movable outer plate in a condition to appropriately respond by movement to a particular potentially deleterious wind speed.
However, many off-ridge roof vents were designed without full consideration of risks of water entry due to high-force wind, such as during a hurricane.

example 1

[0028] One approach to fabrication and assembly is exemplified in FIGS. 3A-C, 4A-C, and 5A. These are not meant to be limiting.

[0029] FIGS. 3A-C provide, respectively, front, transverse section, and cross-sectional side views of one embodiment of a first orifice plate panel 300 of the present invention, for assembly with a second orifice plate panel 400 as depicted in FIGS. 4A-C. Viewable in FIG. 3A are a structural body 302 and six sections 304 of louvers 306 that extend transversely (i.e., from left to right) and extend above like-disposed passages 307 (see FIG. 3C). The structural body 302 further is comprised of end sections 308, transverse ribs 310 between adjacent louvers 306 of a respective section 304, and vertically arranged structural major members 312 and lesser members 314 separating adjacent sections 304. It is noted that the end sections 308 at opposite left and right ends are molded offset to one another so as to provide a lap-type joining when a left side of one pan...

Abstract

The present invention relates to a protective barrier adapted to fit over a roof vent, particularly an off-ridge roof vent, which provides for ventilation and also restricts pass-through of wind-driven rainwater. The barrier comprises two parallel orifice plates, such as louvered panels with passages, that are spaced apart a desired distance by a stagnation zone, so that the device is effective to reduce or eliminate of passage of wind-driven rainwater to the interior of the vent. In various embodiments, the number of louvers in the more outward-disposed orifice plate is greater than the number of louvers in the more inward-disposed orifice plate.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a protective barrier for a roof vent, particularly for an off-ridge roof vent. The barrier may be affixed to existing vents, pre-assembled onto, or integral with vents. The barrier comprises two parallel orifice plates, such as louvered panels, that are spaced apart a desired distance, so as to provide for ventilation and also to restrict pass-through of wind-driven rainwater. BACKGROUND OF THE INVENTION [0002] Roof ventilation devices of various designs have been incorporated into roofs and adjacent building structures, such as soffits, to provide for circulation to eliminate undesired heat build-up, such as in an attic. For example, during hot days air may flow through screened openings in soffits, into an attic space, and out of one or more roof ventilation devices. Roof ventilation devices may be powered, such as attic fans, or passive, such as roof vents. Two common classes of roof vents are ridge vents and off-ridg...
