Abstract
Abstract of the Disclosure This invention relates to a fireplace insulator that blocks off the flue opening. It is inserted in underlying rela-tionship to the fireplace damper. The insulator is similar in construction to an air mattress with sealed together strips and air receiving pockets therebetween. A depending inflation hose has a warning label affixed to it that the flue is closed. At least one sealed together strip is slitted to accommodate the damper handle. In assembly, the insulator is compressed at its ends and along its sides to effectively block the entry of cold air.
Description
S~ ' Abstract of the Disclosure This invention relates to a fireplace insulator that blocks off the flue opening. It is inserted in underlying rela-tionship to the fireplace damper. The insulator is similar in construction to an air mattress with sealed together strips and air receiving pockets therebetween. A depending inflation hose has a warning label affixed to it that the flue is closed. At least one sealed together strip is slitted to accommodate the damper handle. In assembly, the insulator is compressed at its ends and along its sides to effectively block the entry of cold air.
This invention relates to a fireplace insulator that pre-vents heat loss up the chimney when inserted in underlying relationship to the damper, which is an essential component of fireplace construction. Stated differently, the insulator blocks off the entry of cold air into the room.
The insulator is similar in construction to an air mattress with deformability or compressibility that adapts it to various throat openings in the damper area.
Sealed together strips alternate with air receiving pockets in a rectangular perimeter. A depending inflation hose has a warning label affixed to it that the flue is closed. At least one sealed together s-trip is slitted to accommodate the damper handle.
In further description of the invention reference is made to the accompanying drawings wherein, Figure 1 shows end compression on the insulator, Figure 2 shows side compression on the insulator and, Figure 3 shows the insulator in free inflated form.

As shown in Figure 1, insulator 1 underlies damper 2 and is compressed or deformed at its ends for a snug Eit in the throat area of the Elue. An inflation tube is shown at 3.
As shown in Fi~ure 2, the insulator is compressed along its sides to further ens-ure a snug fit and a full closure of the flue opening.
Figure 3 shows the insulator in its free form and inflated.
Within a rectangular perimeter it has air cells and sealed strips between the cells. At least one sealed strip is slitted to provide an opening for a damper handle.
It is thus seen that the device of this invention prevents unused fireplaces from losing inside heat or allowing ingress of cold air.

Claims (3)
1. In a fireplace having a damper, a damper handle and a flue opening, an inflatable insulator insertable under the damper in a compressed state and having at least one slit in a sealed portion of the insulator to receive the damper handle.
2. The insulator of claim 1 wherein a depending inflation tube has a warning that the flue is closed.
3. The insulator of claim 2 wherein the range of its inflation determines its deformability.
