Abstract
FIREPLACE SHIELD/NIGHT COVER
ABSTRACT
In a cover/shield for closing off a fireplace opening, it is known to be composed of a sheet of sheet metal folded on the edges forming a hem with attached pivoting covers over inlet vents to allow controlled entry of combustion air. In this invention a small hole is located in each top corner. These two holes allow the cover to be secured to the fireplace by various means such as with clips or hooks on elastic, rope, wire or plastic lengths or with bolts, screws or nails. A variation of the invention has two metal arms attached to the inside surface of the cover extending up against the throat of the fireplace holding it secure. The cover may need no securing against the fireplace opening other than being placed behind an existing, free-standing fireplace screen or an object leaning against its front surface, eg. a fireplace accessories stand. The cover may be hinged vertically in the middle to collapse together for easier storage when not in use and to be used as a shield while the fireplace is in use where the shield stands freely in front of the fireplace opening by not being extended into its full 180° position.

Description
3 L~
SPECIFICATION
This invention relates to a fireplace opening cover for an additional or alternate method of eliminating -flue loss of warm air when the fireplace is not in use and of controlled entry of combustion air when it is. Such a cover could be variously designed to be decorative. A shut off device of this kind could be placed over the fireplace opening before t'ne fire is completely out, thereby eliminating overnight heat loss with-out danger of combustion products entering the room.
It is common in devices for preventing heat loss or combustion products entering the room, eg. glass doors, iron doors, iron or insulated inserts. Enclosures and covers of this type are, however, overly expensive, cumbersome or of combustible material preventing use while the fire is still smoldering. The glass door variety are more expensive, must be custom fitted and can break from excessive heat. Iron doors are also expensive and need to be custom fitted. Iron inserts with or without an insulated section are expensive and cumbersome in application and for storage.
We have found that these disadvantages may be overcome by providing a thin, non-combustible, unbreakable cover easily removed and stored for normal use of the fireplace. By virtue of the novel constrllction of the present invention, the shield/cover is relatively light in weight while exhibiting suf-Ficient strength and rigidity in use and is formed with a minimum number of simple parts for economical manufacture and low cost. In this way it can be accessible to those who are unable or unwilling to purchase a custom device For the same purpose. It can also be used while the fireplace is in use to dampen the combustion air and thus regulate the fire's fuel consumption.
The cover/shield is unique in that it need not be attached by bolts, screws or latches thus fixing it rigidly to the fireplace but can be free standing in its folding variation or secured in both variations by hooks or clips with elastic, wire, rope or plastic lengths to the corners oF the fireplace through the holes provided in the upper corners. No unsightly holes, protuding bolts or fixture on the fireplace facing will thus disrupt the aesthetic appearance of the fireplace.
f In the drawings which illustrate embodiments of the invention, Figure 1 is a perspective view of one embodiment illustrating its manner of use; Figure 2 is a view of the top left corner of the embodiments; Fisure 3 is an enlarged view of the top center portion of the embodiment in Figure l; Figure 4 is a front view of another embodiment having no hinge in the center; Figure 5 is a perspective view of an embodiment showing a variation in securing the cover to the fireplace opening; and Figure 6 is an enlarged view, in the form shown, of the throat arm used to secure the cover to the fireplace opening.
The present invention is embodied in a folding fireplace shield/
night cover 1 or a non-folding variation 9, both embodiments are comprised of a sheet of sheet metal eg. sheet copper9 galvanized steel, sheet steel or other equivalent corrosion resistant ferrous metal not exceeding 1/8"
in thickness. The outside edges may be finished with any suitable hem, but, in the form shown, are folded over onto the front side to form a single hem 2 resulting in a smooth finished edge for added appearance, safety and strength. Located in the upper left and right hand corners is a hole 4 for the securing of the cover 1 or 9 to the fireplace A by an elastic, rope, wire, or plastic length 7 between a hook or clip 6 at the cover hole 4 and a hook or clip 8 at the fireplace corner B. This method of securing is provided in cases where the cover 1 or 9 is not secured by a free-standing screen or object leaning against the outside surface of it. The above methods require no holes, bolts or fixtures on the fireplace facing to secure the cover 1 or 9 through holes 4 thus allowing the aesthetic appearance of the fireplace to be unaltered when the cover 1 or 9 is not in use. When in use as a cover the invention embodied is placed tightly up against the fireplace opening C with inlet vent covers 3 positioned to completely close off inlet vents 11. The cover is also secured by holes 4 or by a free-standing fire-place screen or other object resting against the outside surface of it. This minimizes the escape of warm room air up the chimney flue and the danger of combustion products entering the room immediately after the use of the fireplace A while the fire is still smoldering during the day or night.
~hen fireplace A is in use, cover 1 can be deployed less than its full 180 extension so as to stand freely in front of the fireplace opening C while still covering the opening at the sides with the over-lapping portion of its length. In this position the invention can act as a shield while the fire is burning, allowing warm air from the fire to rise up through the triangular gap (not shown) at the top between the shield/
cover 1 and fireplace A. The inlet vent covers 3 can be opened, in the form shown, by pivoting them on a rivot or screw 10 to allow controlled entry of combustion air in through the inlet vents 11. Hinge 5 is secured on the inside of the cover 1, in the form shown, at spots 17 by screws, rivots or spot welds on either side of the center edges 15. The hinge rod 12 extends from top to bottom of hinge 5 through shaft 14 created by the rounded edges 13 of hinge 5. In the embodiment shown in Figure 3 hinge 5 is shown secured to cover 1 at spots 17, but a variation to this construc-tion may be the forming of hinge 5 by rounding the center edges 15 of the cover 1 into the rounded edges 13 thus forming shaft 14 within which the hinge rod 12 is held. In this embodiment of hinge 5 as in the embodiment of hinge 5 shown in Figure 3, hinge 5 is the full vertical length of cover 1 but the construction can be such that two shorter hinges could be secured or made from extensions of the cover edges 15 at the top and bottom of cover 1.
Having hinge 5 on the inside of the folding fireplace shield/
night cover 1 also prevents soot and ashes from being brushed off as cover 1 can be folded completely for storage enclosing the side which faces the fire. The folding of cover 1 also reduces its size for convenient storage in the home and for packaging and transportation when marketing it. The embodiment shown in Figure 4 of the non-folding variation 9 is without hinge 5 as shown in Figures 1 and 3, while not as convenient and versatile as the folding cover 1, is formed with a minimum number of simple parts for economical manufacture and low cost.
The embodiment shown in Figure 5 is of the non-folding cover 9, as shown in Figure 4, but with two throat arms 19, in the form shown, fastened with bolts 18 to its inside to secure the cover against the fire-~ t7~l~3 place opening C. The throat arms 19 extend up against the fireplace throa~
D holding the cover 9 from falling away from the fireplace opening C. The embodiment in Figure 6 is of the variation of the throat arm 19 shown in Figure.5. The throat arm 19, as shown in this form, is secured by bolts 18 and nuts 20 through two holes 21. The extra holes 21 are for adjusting the throat arms on cover 9 to fireplaces of various fireplace openings C. A
variation to the throat arm 19 may be the insertion of a hinge (not shown) at the 90 bend above the bolts, so that the folding cover 1 may still be folded for easy storage. In this variation of the throat arm hinge the top part of the throat arm 19 would fold up towards the cover 1. Another variation to the throat arms 19 in Figure 6 may be the insertion of skeleton key shaped holes or the addition of a bracket so that the throat arms 19 could be removed completely when not in use. In this variation cover 1 could still be used in its free-standing mode where it is deployed at less than its full 180 extension, thus allowing a triangular gap between cover 1 and the top of the fireplace A, above the fireplace opening C known as the fireplace breast (not shown).
The invention may be used for other uses other than for fireplace openings, In any instance where a portable shield can provide protection from fire, wind, hot or corrosive substances or dangerous apparatus, the invention has the versatility to be implemented.
