Description

PRIORITY CLAIM

This application claims the benefit of the filing date of pending U.S. Provisional Patent Application No. 60/826,434 filed Sep. 21, 2006 (Our Ref: FIRE-1-1001). The foregoing application is incorporated by reference in its entirety as if fully set forth herein.

FIELD OF THE INVENTION

This invention relates generally to fireplaces, and more specifically, to systems and methods for providing a fireplace seal.

BACKGROUND OF THE INVENTION

The use of fires domestically can be traced back nearly one million years. Initially fires were built in the middle of hut-like structures to provide maximum heat distribution, and smoke escaped through incidental holes in the roof of the structure. About half a million years ago, holes and chimneys began to be built into houses so that smoke could escape more easily. When houses became two stories, however, chimneys were moved to the outside of the building to protect wooden walls and floors that were used to build multi-story buildings. This was the birth of the modern fireplace.
Today there exists a wide variety of fireplaces that take on a myriad of embodiments and that can occupy various places within the home. What all these fireplaces have in common, however, is first an opening that allows a user to put combustible material in the fireplace and enjoy the heat, light and smell that accompanies a burning fire. Second, there is a chimney that conveys smoke and other combusted gasses out of the house. Additionally, fireplaces can have multiple chimneys or vents that facilitate more efficient airflow to and from a fire. Although the chimney is necessary to make the fireplace safe, it does also have negative impacts on a home environment, especially when the fireplace is not being used.
When a fireplace is not being used, any channel that conveys smoke and other gases out of the house is typically open. Accordingly, air, gasses and other matter from outside of the house can travel into the house. For example, when it is cold outside, persons who reside in a house typically want the house to be warm and the fireplace allows cold air from outside to cool the house. Conversely, when it is hot outside, persons who reside in a house typically want the house to be cool, and the fireplace allows hot air from outside the house to heat the house. Although modern air-conditioning can typically keep a home at a constant temperature despite the influence of hot or cold air passing into the house through the fireplace, this comes at a substantial and undesirable energy cost. The cost of energy to heat or cool a home is becoming increasingly expensive and there has become an emphasis is decreasing this cost by making homes more energy-efficient.
One way to make a home more energy-efficient is to stop or reduce the air-flow through the fireplace when the fireplace is not being used. Many systems and methods of sealing a fireplace are known in the art, however these systems and methods suffer from being difficult to use, being bulky and difficult to store, and being unable to fit multiple sizes of fireplaces. First, many systems for sealing a fireplace are made of solid materials, which facilitate a good seal, but are bulky, unable to fit into a wide variety of fireplace sizes, and difficult to store when not in use. Second, of those systems of sealing a fireplace that are configurable to be sized to various sizes of fireplaces, these systems are nonetheless limited to very few fireplace sizes and are difficult and cumbersome to use. Furthermore, many of these systems require that permanent fixtures be attached to the fireplace, which can result in undesirable damage or unsightly appearance.
What is needed, is a fireplace seal that is lightweight, easy to use, configurable to fit in a wide variety of fireplaces, and compactable for easy and discrete storage. Therefore, what are needed are systems and methods for providing a fireplace seal.

The second rod 115 is enclosed in a pouch, which is defined by a length of the sheet 120 that has been folded onto itself and then coupled at the second sheet coupling 135.
The sheet 120 is rollable with the first rod 110, such that the height of the fireplace seal 100 is approximately, roughly or equal to the height of the opening of the fireplace 650. In one embodiment, the sheet 120 can be rolled with one, both, or neither of the first and second rod 110, 115 to achieve a height of the fireplace seal 100 that is approximately, roughly or equal to the height of the opening of the fireplace 650. By configuring the fireplace seal 100 to be of approximately, roughly or equal to the height of the opening of the fireplace 650, a seal can be achieved between the horizontal top and bottom edges of the fireplace seal 100 and the horizontal top and bottom of the opening of the fireplace 650.
FIG. 9 is a side cross sectional view of a fireplace seal 100 being used in a fireplace 650, the fireplace comprising a floor vent 960 and a chimney 970, in accordance with an embodiment of the invention. The fireplace seal 100 comprises a first and second rod 110, 115, a sheet 120, and a first and second sheet coupling 130, 135 as described in reference to FIGS. 1-8. The first rod 110 is enclosed in a pouch, which is defined by a length of the sheet 120 that has been folded onto itself and then coupled at the first sheet coupling 130. The second rod 115 is enclosed in a pouch, which is defined by a length of the sheet 120 that has been folded onto itself and then coupled at the second sheet coupling 135.
The floor vent 960 is a conduit in the floor or base of the fireplace 650 that allows air, smoke or other matter to flow in or out of the floor vent 960. Additionally, the chimney 970 also allows air, smoke or other matter to flow in and out of the chimney 970. Typically, both the floor vent 960 and chimney 970 are conduits to the exterior of the house and therefore the external environment. Thus, the fireplace seal 100 provides a complete or partial seal for the fireplace 650.
In further embodiments, the fireplace seal 100 can facilitate a partial or complete seal about the opening of a fireplace that is approximately, roughly or exactly any polygon or other shape, either regular or irregular. In one embodiment the fireplace seal can be used in any part of a fireplace, window, door, vent, or other opening. In a still further embodiment, the fireplace seal 100 can comprise additional systems or members that facilitate a seal, including, but not limited to, rubber, plastic, magnets, or ceramic. In yet a further embodiment, the fireplace seal 100 can be rolled up into a relatively small and compact form and stored for later use. In an alternate embodiment, the fireplace seal 100 can be folded one or more times into a relatively small and compact form and stored for later use. In a similar embodiment, the fireplace seal 100 can be reduced in size by compressing the first and second rods 110, 115.
FIG. 10 is a perspective view of a fireplace seal having a skirt, in accordance with an embodiment of the invention. In one embodiment, the fireplace seal 100 includes the sheet 120 as described in reference to FIGS. 1-9. The sheet 120 further includes a skirt 1002 disposed about the sheet 120 perimeter. The skirt 1002 provides a flexible extension to the sheet 120 and is configurable to being disposed against a wall of the fireplace 650 to assist in preventing air flow from slipping through any gaps between the sheet 120 and the fireplace 650. In one particular embodiment, the skirt 1002 further includes skirt magnets 1004 for removably coupling the skirt 1002 to a metallic mount 1006 on the fireplace 650. In certain embodiments, the skirt 1002 extends only partially about the sheet 120 perimeter. In a further embodiment, the skirt 1002 further includes one or more horizontal skirt segments (not illustrated) for being disposed against a wall of the fireplace 650 when the sheet 120 is height adjusted. In a similar embodiment, the skirt 1002 further includes one or more vertical skirt segments (not illustrated) for being disposed against a wall of the fireplace 650 when the sheet 120 is width adjusted. The vertical skirt segment and the horizontal skirt segment can include magnets. In another embodiment, the skirt magnets 1004 are substituted or complimented with another fastening mechanism. In yet a further embodiment, a plurality of layered skirts 1002 are employable to further assist in preventing air flow from slipping through any gaps between the sheet 120 and the fireplace 650.
In an additional embodiment, a decorative covering can be removably coupled to the sheet 120 to match a room décor where the fireplace 650 is located. The decorative covering can be coupled to the sheet 120 using magnets or some other fastener and can partially or fully cover the sheet 120. In yet another embodiment, paints are employable to decoratively color the sheet 120.
While preferred and alternate embodiments of the invention have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention.
