W. P. GARRE'D HEAT REFLECTOR FOR COMPRESSION TYPE AIR CONDITIONERS Filed May 16, 1855 IN V EN TOR. MY/lbm R Gar-red BY United States HEAT REFLECTOR FOR COWRESSION TYPE AIR CONDITIONERS William P. Garred, Box 127, Onawa, Iowa Filed May 16, 1956, Ser. No. 585,339
2 Claims. (Cl. 62-262) My invention relates to a device to be attached to compression type air conditioners.
An object of my invention is to provide a device which will reflect the hot morning sun or the sun under other conditions so that the heat of the sun will be reflected off of the air conditioner, thereby materially increasing the resultant efliciency of the air conditioner.
A further object of my invention is to provide a very simple struction for this purpose and which can be very easily installed consistent with the structure of the air conditioner unit.
With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:
Figure 1 is a plan view of the arrangement as attached to the air conditioner,
Figure 2 is a side elevation of Figure 1,
Figure 3 is a detail, and
Figure 4 is a modification.
My invention relates to a reflector device which can be conveniently and easily installed on to a conventional compression type air conditioner to reflect the rays of the sun so as to materially increase the efliciently of the air conditioner which otherwise has a decreased efiiciency due to the beating of the sun on exposed surfaces.
I have used the character to designate generally that portion of the air conditioner which extends out beneath the window 11 and rests upon the sill 12 with the balance of the air conditioner not being shown and which balance is in the room itself. I have further used the character '13 to indicate the usual louvres which area part of the side walls 14 of the air conditioner, the character 15 indicating the top wall, the character 16 the bottom wall and the character 17 the outer vertical wall. I have used the character 18 to designate the reflecting surface itself, this reflecting surface being in the form of a flat sheet of any suitable material which is properly coated with the requisite coating of any type to reflect the rays of the sun and to thereby protect the cooling unit. It will be noted that the member 13 is positioned substantially at the angle shown in Figure 2, thereby more completely protecting the unit and providing the most efiicient angle for reflecting purposes.
Passing through the reflecting member 18 are the bolts 19 which pass through the inclined portions 20 of suitable straps which straps include the further portions 21 and 22, the wing nuts 23 serving to secure the bolts 19 and the reflector 18. The straps 22 engage the top wall 15 and are joined at 24 by a transverse strap 25, the junction at 24 being made by tapped openings if such is desired to permit disassembly of the straps for shipping purposes.
To secure the arrangement in the angle as shown I pro- Patented June 21, 1960 vide pairs of fabric straps 26 of which there can be either a pair or more at either side, these straps having the buckles 27, these straps also engaging at 28 the hooks 29 which hooks are engaged beneath the edges of any of the louvres 13 The straps are doubled over as shown and will pass about the bar portions 22 and can thence be tightened by means of the buckles 27, so that by virtue of this arrangement any width of air conditioner can be accommodated.
The member 18 as shown can include a small bead around the perimeter thereof or can be made in a variety of other cross sections for strengthening purposes if desired. The vertical portion 21 of the straps permits the member 18 to be spaced from the upper corner of the unit to permit ventilation at this point.
Figure 4 shows a modification of one of the straps having the portions 20, 21 and 22, and in this case the portions 22 can include openings 30 through which ordinary metal screws can be placed and attached to the top Wall 15, and in this manner the reflector can be supported 5 -may be reasonably included within their scope.
I claim as my invention:
1. A heat reflector for air conditioner casings comprising a flat reflecting plate positioned adjacently to the outwardly extending portion of said air conditioner casing to thereby reflect sun rays therefrom, said reflecting plate being angularly positioned with respect to said casing and being positioned generally adjacently to the upper outer end thereof, means for attaching said plate to said casing including a pair of straps attached to said plate including horizontally positioned portions for attachment to said casing, means for attaching said straps including further fabric straps passing about said straps, hooks attached at the lower terminals of said fabric straps for engaging certain of the louvres of said casing at the sides thereof.
2. A heat reflector for air conditioner casings comprising a flat reflecting plate positioned adjacently to the outwardly extending portion of said air conditioner casing to thereby reflect sun rays therefrom, said reflecting plate being angularly positioned with respect to said casing and being positioned generally adjacently to the upper outer end thereof, means for attaching said plate to said casing including a pair of straps attached to said plate including horizontally positioned portions for attachment to said casing, means for attaching said straps including further fabric straps passing about said straps, hooks attached at the lower terminals of said fabric straps for engaging certain of the louvres of said casing at the sides thereof, a transverse bar secured at the terminals of said horizontally positioned portions, said straps having vertical portions whereby said reflecting plate will be positioned at a spaced distance above said corner.
