FIELD OF THE INVENTION

The present invention is a system and device for ventilating the attic of a dwelling. More specifically, a serviceable soffit ventilator is provided having a removable and re-usable filter.

BACKGROUND

Excessive heat and moisture trapped in an attic or other space underneath the pitched roof of a structure can damage the roof, can damage the remainder of the structure and can promote mold and decay within the attic. To avoid these effects, the ambient air space between the roof and dwelling ceiling, referred to as the attic, must be constantly ventilated, and replaced with fresh contiguous outside ambient air.

During daylight hours, the sun shining on the roof warms the deck surface, causing the deck to become warmer than the ambient air. The warm roof deck heats the ambient air in the attic space. During the cold weather, heat and moisture from the living space migrate into the attic space which warms the air in the attic. The warm and moist air within the attic space expands, becomes buoyant and tends to rise. Because the roof is pitched, the warm and moist air stratifies, with the peak of the attic becoming warmer than the floor of the attic. This stratification of unequal temperatures during cold weather can cause a condition referred to as “ice damning”, whereby, the top of the roof absorbs the stratified heat and becomes warmer than the central and lower sections of the roof, thereby melting any accumulated ice or snow from the top of the roof ridge causing the melted ice or snow to gravitationally.

In addition, the enclosed attic space is vulnerable to wind gusting through roof and gable vents and entering the attic when the wind pressure is greater than the exhaust pressure of the ridge or roof exhaust vents. This condition causes loose debris, dust, insulation materials and other disturbed materials resident in the attic to become airborne and randomly relocate within the attic space. In most cases, this debris lands and stays on the attic side of the eave or soffit vent, blinding the filter component of the soffit vent and rendering said vent incapable of freely providing unrestricted necessary intake air.

Traditional soffit and eave intake vents have a fixed and permanent filter media or “screen” affixed to the vent housing and permanently captured between the vent housing and soffit or eave substrate. The filter component of the fixed vent is necessary to prevent unwanted insects, rodents and other detrimental debris from being drawn into the attic space either through convection, vacuum or migration. Over time, and starting immediately after the installation of traditional soffit vents, the fixed filter screen begins to become blinded by airborne organic material, including but not limited to, dust, dirt, pollen, leaves, organic material and mud. The debris is small enough in size to pass through the vent frame air openings, but large enough to become trapped in the smaller passages in the screen material, rendering the filter to be compromised, blocked and unable to deliver adequate air flow to the attic space.

Further, traditional methods contemplate the permanent installation of the captured soffit vent filtered housings, affixing them to the eave/soffit structure with nails, screws or adhesives with no provision for post installation removal for maintenance or service. When the fixed filter material becomes blinded from either the intake or exhaust side of the filter, physical removal of the entire vent housing is required to purge the filter and remove the debris captured in the intake or exhaust side of filter. This removal procedure normally destroys the vent housing, rendering it unusable, and damages the eave or soffit structure that the vent was affixed thereto.

The present invention overcomes the shortfalls of the prior art by providing a soffit vent that includes a replaceable and/or reusable filter media. In addition, the soffit vent provides a simple method for the filter media to be removed, cleaned, and re-inserted. In addition, the soffit vent of the present invention provides for additional types of inserts that can block the flow of air into the attic space in case of a fire or store scenarios, wherein restricting airflow to the attic is desired.

BRIEF SUMMARY OF THE INVENTION

The present invention, as disclosed and described herein, in one aspect thereof, is a system and device for the ventilating of an attic or other area under the roof in a new or existing dwelling. The apparatus is a soffit/eave air intake vent that is comprised of a fixed louvered frame which incorporates a separate companion filter which is removable, serviceable, and cleanable and reusable and which further mates with the fixed louvered intake vent.

The present invention, in one aspect, provides a user serviceable attic air intake vent that allows the user to restore the net free air flow of the soffit filter media, without the requirement of removing and replacing the affixed vent housing from the eave or soffit substrate, or the requirement to replace the soffit air vent entirely.

In addition, the present invention provides an attic soffit system configured to enable ventilation of a building having and attic and soffit, the system having a one piece frame component having an outer flange surrounding a corresponding opening in the dwelling's horizontal eave or soffit structure. Further, the soffit vent includes a louvered cavity frame that is formed with air intake louvers on the opposing surface to the attic enclosure opening. The soffit vent includes four sides, wherein at least one side includes a slot for inserting and removing a filter insert. A separate perforated metal filter insert is also provided which has a flat metal perforated rectangle with an extended pull-tab at one end. In addition, the vent includes a plurality of attachment holes on its perimeter for attachment and removal of the vent from a surface, such as a wall panel.

Further, the frame of the soffit vent is formed from one piece of galvanized steel and the filter is stamped from one piece of metal and includes more than 50% net free open surface area for the incoming air to pass into the attic space. In addition, the frame can be powder coated to insulate the metals from corrosion. Further, the device allows the user to remove, clean and reinsert the filter media. More specifically, the soffit vent of the present invention allows the user to remove the filter media without the removal of the vent frame from the structure. For example, this allows the user to clean the soffit vent insert safely away from the building with high-pressure water or air without removing the vent frame from the building, thereby protecting the structural and aesthetic integrity of the eave/soffit structure or wall panel.

DETAILED DESCRIPTION

FIGS. 1-2 illustrate one embodiment of the serviceable soffit vent assembly 100. Here, vent 100 includes a frame 150 having a first end 150a and a second end 150b, top end 150c and bottom end 150d. In the current embodiment, frame 150 has a rectangular configuration, however, it contemplated within the scope of the invention that frame 150 can be any size, dimension, or shape, including but not limited to a square, circle, cylindrical, oval, ellipsoid, triangular, asymmetrical, or any polygon having three or more sides. Further, frame 150 includes a plurality of fixed louvered openings 154. In the current embodiment, there are five columns of louvers, wherein each column has 13, thereby the vent having a total of 65 louvered air openings. However, it is contemplated within the scope of the invention that there can be any number of louvers, louvers columns, air intake openings, or any arrangement or configuration of louvers or air intake openings. In addition, ends 150a-150d of the frame form a flanged perimeter 156 with a plurality of openings 152 that allow the vent assembly 100 to be secured to an underneath surface of a roof or soffit structure 900, as shown in FIG. 6. In the current embodiment, openings 152 can receive one or more threaded screws or nails to secure the vent. However, it is contemplated within the scope of the invention that any number of methods or devices can be used to secure vent 100 to the underneath surface of a roof, including but not limited to, adhesives, magnetic, straps, solder, welding, rivets, latches, snap-fit, or press-fit.

Still referring to FIGS. 1-2, on the first end 150a of frame 150, an opening 158 is provided that allows the vent to receive a removable filter insert 110. Specifically, opening 158 is a substantially rectilinear or rectangular configured slot that allows filter insert 110 to be slideably inserted and/or removed from frame 150. However, it is contemplated within the scope of the invention that opening 158 can be of any configuration, dimension, or shape, including but not limited to ellipsoid, oval, rounded corners, mitered corners, or any polygon having three or more sides. Further, it is contemplated within the scope of the invention that opening 158 can be on either one or more of ends 150a, 150b, 150c, and 150d. Here, removable insert 110 can be reusable or disposable. If reusable, it can be removed, cleaned, and quickly re-inserted within the vent frame. There are many known cleaning methods within the art, such as using high-pressure water or high-pressure air to clean the filter while it is isolated from the vent frame. Hence, by incorporating a removable filter insert, a user does not need to remove and re-install a new soffit vent. Other cleaning methods can include, but are not limited, various solvents, bleach, hydrogen peroxide, soap, brushing, detergent, ultrasound, air, water, and heat.

Still referring to FIGS. 1-2, removable filter insert 110 has a substantially rectilinear or rectangular configuration. However, it is contemplated within the scope of the invention that insert 110 can be of any configuration, dimension, or shape, including but not limited to ellipsoid, oval, circular, rounded corners, mitered corners, or any polygon having three or more sides. In the current embodiment, filter insert 110 is made of galvanized steel or metal material and is stamped from one piece of metal. However, it is contemplated within the scope of the invention that any type of material can be used in lieu of steel or metal.

Filter insert 110 further includes a plurality of apertures, perforations, or pores 114 across its surface area that help filter incoming air flowing through the vent and into an attic space. In the current embodiment, approximately 50% of the surface area of the filter includes pores 114. However, it is contemplated within the scope of the invention that any number of pores can be provided within insert 110, including from 5% up to 95% of the surface area of insert 110. In other embodiments, any number of additional layers of filtering material or filter media can be provided on the top or bottom surface of insert 110, or in lieu of insert 110.

In addition, insert 110 includes a projecting pull-tab 112 at one end of the filter with an aperture there through. Tab 112 assists the user in removing the insert from the frame. It is contemplated within the scope of the invention that in lieu of a tab, any type of mechanism can be used to assist a user from removing the filter, including but not limited to a handle, latch, nip, grip, treaded surface, hook, and ring.

FIG. 3 illustrates another embodiment for an insert 210. Here, insert 210 does not include pores or apertures and is intended to block or prevent airflow from flowing through the vent and into the attic space of a dwelling. Similar in operation to insert 110, insert 210 is removable and also slides within frame 150 via an opening on one side of the frame. Further, insert 210 can also include a projecting pull-tab 212 to assist the user in removing insert 210 from the frame. In certain emergency scenarios, such as a fire scenario within a dwelling or the attic of the dwelling, it is desired to reduce the amount of air flowing into the attic to prevent further exacerbation of the fire and further help improve the choking and/or distinguishing of the fire within the dwelling or within the attic of a dwelling. Hence, in a fire scenario, the configuration of vent 100 allows a user to quickly remove filter insert 110 from the frame 150 and replace it with insert 210, thereby preventing fire from additionally spreading to the attic and assist distinguishing the fire by preventing additional airflow from reaching the attic space. In addition, insert 210 can also be used in storm or extreme weather or environmental situations, such as hurricanes, tornados, typhoons, floods, and environmental disasters, thereby preventing unwanted air (such as turbulent air), water, dust, snow, ice, chemicals, smoke, or other airborne debris or substances from entering the attic space.

FIGS. 4-5 illustrate another embodiment for an insert 310. Here, insert 310 does not include apertures or pores and is also intended to block airflow from flowing through the vent and into an attic space of a dwelling. Similar in operation to insert 110 and insert 210, insert 310 is removable and also slides within frame 150 via an opening on one side of the frame. Further, insert 310 can also include a projecting pull-tab 312 to assist the user in removing insert 310 from the frame. In addition, insert 310 includes two adjacent flaps 320 on each side of the insert that allow the insert to be securely fit within frame 150. Specifically, flaps 320 are comprised of one end 322 and an opposing adjacent end 324 that protrude outwardly with respect to each other. Further, ends 322 and 324 are flexible resilient components that can pivot about one common axis. Hence, ends 322 and 324 can be bent and pressed towards each other so that when the insert is inserted within frame 150 they can provide a secure engagement and fit within the frame. Further, in another embodiment, ends 322 and 324 can also be incorporated into the insert 110 embodiment, thereby further securing insert 110 within the vent. In other embodiments, either of inserts 110, 210, or 310 can include a sealing substance or material, such as a rubber or any other suitable material, affixed around the outer perimeter of the inserts, thereby providing a secure and sealed fit of the inserts within frame 150. Further, in other embodiments, vent 100 of the present invention can be affixed to any surface of a dwelling, including but not limited to the soffit structure, soffit at rake, soffit at eave, underneath surface of a roof, wall panel, fascia, pipes, or any other suitable area of a dwelling. In addition, a dwelling can include any number of soffit vents 100 affixed to its structure.

It will be apparent to those skilled in the art that various modifications and variations can be made in the serviceable soffit vent apparatus.
