Abstract:
The invention provides a readily deployed insulating seal for the hearth opening eliminating airflow to and from the chimney flue that utilizes a safe and uncomplicated expanding Pneumatic filled mass that acts as a closure preventing heat loss from exiting the room and blocking cold air from entering.

Description:
BACKGROUND 
       [0001]    Heat loss and the ability of homes and businesses to conserve valuable energy has been a fundamental goal of many for a very long time. Everyone knows to close doors and windows in inclement weather and billions are spent on insulation and high-tech insulation methods, but at times the simplest and seemingly the most obvious failures are overlooked. Often times a chimney damper is simply an un-insulated metal flap with less than a perfect seal which allows air to flow past in both directions. Energy someone pays to produce flows right past primarily unchecked, and the elements can similarly flow in creating a need to expend more energy to mitigate the inflows or losses. A reasoning individual would never leave a window cracked open in the dead of winter and pumping air conditioned air out the flue is expensive and wasteful. This invention in one of its many manifestations creates an airtight barrier and insulates at the same time. 
       SUMMARY 
       [0002]    The issue is simple; how do we seal off an area that is not uniform in size and/or dimension to eliminate the loss? The invention is scalable and malleable to the point of forming itself to virtually any opening and creating an airtight seal that insulates as part of its basic design by placing an air barrier between the inside and outside elements. Deployment is fast and takes no special skill or ability. Simply placing the invention into the opening roughly in the center of the space and inflating the device with one of the several available methods is all it takes. The device will form to the area as it is inflated creating a solid and insulated seal.

     NOTATION, CLASSIFICATION, AND TERMINOLOGY 
       [0006]    Terms (defined as a name or word for something) are used throughout the following descriptions, discussions, and claims that refer to particular systems, components, and processes. The uses of these “terms” are in no way intended to be the exclusive and only representation of the described systems, components, and processes and are only intended to reference an embodiment of the noted systems, components, and processes. As is the case in most industries and as far as that is concerned most situations, one person may refer to a system, component, and/or process with one “term” where another may use a different “term.” The “terms” contained herein are not intended to distinguish between systems, components, and processes that differ in name but not function.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0008]    There are multiple embodiments of the invention that facilitate the same result. The following discussions reference several of those embodiments but is in no way intended to comprise the only embodiments. The discussions herein have broad application, and the discussions are intended to be exemplary and not exclusionary. The exemplary nature of the discussions herein is not intended to limit the scope or embodiments of the invention. 
         [0009]      FIG. 1  illustrates a configuration of the device in accordance with the embodiment of the invention.  FIG. 1  shows the basic design elements of the invention. The device  100  incorporates a fire retardant material with a shaped top that can mold to any combustion chamber ceiling  101  that channels air and flue gasses into a flue pipe  102 . All fireplace hearths have a conical or tapered ceiling to the combustion chamber  101  that channels the air and flue gasses to a central location where the flue pipe  102  is located allowing for a natural path up the flue and outside the structure. The device  100  uses pressure exerted on the top of the device against the ceiling of the combustion chamber  101  with the malleable composition of the device  100  to create an airtight seal regardless of the exact configuration or design of the combustion chamber ceiling. The “pressure” previously noted is created by the expansion of the device  100  in the hearth  103  by means of the Pneumatic fill valve  104 . This expansion substantially fills the hearth opening  103  and exerts pressure through contact with the floor and back of the hearth opening  103  and the ceiling of the combustion chamber  101 . The invention will be available in variable sizes to accommodate most conventional fireplace openings and shall be scalable within certain parameters to accommodate variances in design and construction. 
         [0010]    The device  100  creates an air pocket contained inside of the malleable material which has insulation values that vary depending on the size of the hearth, size of the flue, and proper installation of device  100 . 
         [0011]      FIG. 2  illustrates one embodiment of the Pneumatic fill valve  104  from  FIG. 1 . For illustrative purposes in  FIG. 2  and this detailed description of this embodiment of the Pneumatic fill valve we will maintain the same numeric reference for the Pneumatic fill valve  104 . The Pneumatic fill valve  104  is integrated into the lower front area of the device  100  [ 201 ]. This embodiment utilizes a simple oversized flap valve design  202  that allows the applied Pneumatic source to pass by pushing past the flap substantially unrestricted. Once filling of the device  100  is complete and the applied Pneumatic source is stopped the oversized flap valve  202  will be pushed by the escaping Pneumatic material closing the valve and sealing the opening with the Pneumatic material contained in the device. Once the filling stage is complete the valve can be more securely sealed for a prolonged application of the device by pressing the ribbed Pneumatic fill valve seal  203  which is tethered to the valve  204  into the ribbed cylinder of the Pneumatic fill valve  104 . To deflate the device you simply pull up on the valve seal relief tab  205  and use any blunt ended object long enough to reach the oversized flap valve  202  and depress the valve creating a path for the Pneumatic material to escape. Continue to depress the valve until the device is fully deflated.
