Thermal insulating window and entrance portable cover/pad

## Abstract

An inexpensive, lightweight, reusable and detachable or removable insulation device for residential and commercial dwellings and similar heated structures. The device has an inner-portion insulating pad adapted to fit inside of a typical entrance or window unit framing. The device further has an outer-portion insulating pad adapted to overlap the window or entrance framing. The outer-portion insulating pad is provided fasteners so as to be secured to the building wall structure outside of the framing and surrounding the window or entrance framing by. During cold weather months, the present invention will greatly restrict warm air from escaping between small crevices in inept window systems by fitting firmly into window framing using a insulating material, thus creating a thermal barrier and improving the efficiency of the furnace by reducing the demand for electricity or fuel consumption.

## Background
BACKGROUND
1. Field of Invention
This invention relates to detachable insulating covers that are particularly suited for use in connection with windows and entrances of residential and commercial dwellings.
2. Prior Art
It is known from prior art that heat transfer through the windows and entrances of residential and commercial dwellings can be greatly reduced through the use of insulating covers.
Prior art has shown application of thin sheets of transparent plastic material and the like affixed to the windows and entrances. This method does offer some thermal insulation properties; however, in older dwellings with inept windows and entrances this method will have very little if any effect. In addition this application has problems with condensation build-up when in use.
Another solution of prior art in U.S. Pat. No. 4,610,292 (1986) suggested the use of insulated window shades and curtains. In this method window shades have a separate or detachable insulating layer behind the cloth fabric of shade or curtain. The insulating layer could be added during winter months and removed during the warmer months. This method did offer a portable way of insulating window areas; however this method did very little for drafty inept window systems for older dwellings. In cold weather months if a furnace is used to heat the dwelling, the produced warm air will rapidly escape through the drafty windows making it uncomfortable and thereby lowering the efficiency of the furnace or requiring a greater increase in fuel consumption to warrant eliminating the problem.
Another solution of prior art in U.S. Pat. No. 4,131,150 (1978) suggested the use of a window enclosure that is permanently mounted inside of window framing. The window enclosure used siding panels to remove or add insulating material. This method required a permanent alternation to the window framing.
These methods listed above are known to suffer from the following disadvantages:

    
    
        a) poor thermal protections during cold weather months, by permitting warm air to escape between small crevices in inept window systems;
        (b) neither system is designed to have an insulating layer fit firmly inside the window framing while utilizing surrounding wall element for fastening without altering the window and/or framing itself.
    
    


SUMMARY OF THE INVENTION—OBJECTS AND ADVANTAGES
A need for a long period of time has existed for a portable window insulating system that is simple and cost effective to install at first application, which will not alter the current window or entrance framing.
An important object of the present invention is to enable a person to remove the cover from the window framing is a simple manner.
Another important object of this invention is to provide a thermal barrier which seals around the edges of the window framing with an insulating layer and which may be adjusted to overlap around window framing edges onto the adjacent wall area.
During cold weather months the present invention, when installed inside a dwelling, will greatly restrict warm air and radiant heat from escaping between small crevices in inept window systems by fitting firmly into window framing using an insulating material.
This lightweight portable and removable insulating cover is placed over the interior-side generally (or the exterior) of typical commercial and residential building windows and entrances, providing added thermal protection inside of the dwelling, whereby creating a thermal barrier.
The present invention could be modified to have a viewer's opening for viewing out of the window/entrance when cover is installed. The present invention can also be modified to have decorative designs or embroidery on the exterior of device that is attractive and decorative to the eye of the beholder on the interior or exterior of the house.
This insulating cover can also be fabricated as a solid one-piece pre-molded insulating material using various molding/casting manufacturing techniques or using various fibrous felt-type insulating materials.
It is still another object of this invention to provide a complete window assembly that is simple, reusable, easy and economical to maintain.
This invention will be better understood and appreciated from the following detailed description of one embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings.

Summary, Ramifications, and Scope
As previously mentioned the following reference part numerals have additional advantages in that;
Fabric material 03 may be made of any suitable material such as flame-retardant material, cotton, plastic, polyester, paper with aluminum foil backing, nylon, and the like.
The fiberglass felt-type insulation 09 may be any conventional type of insulation such as fiberglass, fiberglass sheets with aluminum foil or its equivalent, various plastic foams, foam rubber, and any conventional insulation material including flame retardant material, which can control the transfer of heat and prevent the escape of warm air from the interior of the dwelling.
In addition to Velcro® hook and loop fasteners 06, other fasteners could be used such as snaps, hooks, or any other types of conventional fastening means.
While nylon threading material 04 has been mentioned, it will be obvious that in addition to nylon threading material 04, snap fasteners, staples, epoxy or other glue-like material or heat seals can be used.
A particular advantage of the present invention lies in the fact that edge portion of the outer pad 01 proficiently seals around the edges of the window unit 21. This seal greatly restricts the passage of warm air from inside the dwelling and is easily removable. If the fasteners 06 are appropriately spaced along the window unit framing 21, the insulating section of the present invention will greatly improve the air tightness of the space between the window unit 21 and the insulating cover.
Referring to FIG. 5 fasteners 06 are shown attached to the wall area surrounding window unit 21. These fasteners could also be mounted directly to the window unit 21 framing. This method could benefit fixed sash commercial window units with metal framing.
The outer portion pad 01 could be constructed omitting the fiberglass insulation 09 shown in FIG. 4, thus just using a layer of fabric material 03 or vinyl and plastic-like materials. This method would provide a smooth, flush and sleek appearance inside of the dwelling, thus lending itself to various decorative and ornamental designs, patterns, pictures, textures, writings and embroidery.
Also an additional advantage of the present invention lies in the fact that the materials selected to manufacture this device; when used in combination could produce stain resistant, water-resistant and moisture-resistant properties which would improve the effectiveness of the device. This could include the fabric material 03, fibrous polyester filler batting 07, and fiberglass insulation 09.
Also an additional advantage of the present invention lies in the fact that the materials selected to manufacture this device; when used in combination could make the device a bullet-proof or resistant barrier when installed at windows and entrances. This ramification could have great law enforcement and military potential.
Although the description above contains many specifics, these should not construed as limiting the scope of the present invention but as merely providing illustrations of the presently preferred embodiments.
Thus the scope of this invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
