Benefits of technology
"The present invention provides an apparatus for installation in a foundation wall for air ventilation and passage of flood water. The apparatus includes a housing with at least one interior screen stop and at least one housing recess, a screen with at least one screen flange, and an exterior stop. The screen can be inserted into the interior screen stop recess and the exterior stop can be inserted into the exterior sill section channel and the exterior head section recess. The technical effect of this invention is to provide a reliable and effective apparatus for air ventilation and flood water passage in foundation walls."
Problems solved by technology
The disadvantage of an engineered foundation flood vent is that building codes typically require specialized structural engineering of the foundation if an engineered foundation vent is to be utilized.
When the foundation air vent is to be used as a multi-purpose air and flood vent, the use of a vapor barrier in a flood-prone area can create a hazard during flooding since the plastic can become buoyant, it may rise with the rising flood water, and it may be forced against the foundation wall, potentially covering any flood grates and preventing the passage of flood water therethrough.

Embodiment Construction
[0023]The present invention is a dual purpose foundation vent that provides both air ventilation and flood relief for an enclosed under floor area (e.g., a garage, basement, crawlspace, etc.). The foundation vent of the present invention allows free passage of flood water from an enclosed under floor area while simultaneously maintaining air movement with the enclosed under floor area such that moisture latent air may be removed from such area. The foundation vent also includes a screen to prevent items such as insects, small animals, and the like, as well as debris and organic matter, from entering the under floor area including buoyant materials carried to the face of the screen during a flood. A removable screen and exterior screen stop allow the owner to easily inspect, maintain, clean, and repair the foundation vent during routine maintenance and to ensure that such vent is in proper working condition (i.e., it is a properly functioning foundation opening). The design further a...

Disclosed is a foundation vent that provides air ventilation and flood relief for an enclosed area. A screen is included to prevent items such as insects, small animals, debris, and organic matter, including buoyant materials due to a flood, from entering the enclosed area. A removable screen and exterior screen stop allow the owner to easily inspect, maintain, clean, and repair the foundation vent. The foundation vent is also designed as a non-engineered, non-mechanical opening, which allows the air and flood water ratings of the foundation vent to be based upon the actual net clear open area. Such design eliminates the need for a vapor barrier and / or specialized structural engineering of the foundation. The dual operation of the foundation vent as a flood grate also allows rising flood water to penetrate and recede from the enclosed area, which equalizes the hydrostatic pressure on either side of the foundation wall.
Description
BACKGROUND OF THE INVENTION[0001]Embodiments of the present invention generally relate to multi-purpose vents. More specifically, the present invention relates to vents that allow the passage of both air and flood water therethrough.[0002]The use of foundation vents for ventilation of an enclosed under floor area such as a crawlspace, garage, basement, or the like is known. Some such vents include irremovable components permanently installed in the foundation. Other such vents include hinged screens, louvers, or the like to facilitate cleaning or maintenance as well as access to the under floor area.[0003]Flood grates are also known. Such grates are commonly used in areas designated by the Federal Emergency Management Agency (“FEMA”) as flood areas. These grates typically pass through a perimeter foundation wall of an enclosed under floor area to allow rising flood water to penetrate and recede from the enclosed under floor area, which equalizes the hydrostatic pressure on either si...
