Application December 9, 1955, Serial No. 552,154

2 Claims. (Cl. 219-34) This invention relates to improvements in space heaters "and particularly those heaters which take advantage of the radiant heat rays in heating a room or other enclosure.

An object of the present invention is to provide a radiant heating assembly which is designed primarily to be used in the upper corner of a room, the assembly being constructed with a reflector that is insulated from its supporting means so that there is a minimum of heat loss by conduction. One of the features of the invention is the reflector that is insulated from its supporting structure so that as it becomes warm, the reector becomes a secondary emitter of radiant heat energy.

A further object of the invention is to provide a cove molding type radiant heater which is easily installed by fastening a mounting plate at the junction of the walls and ceiling, locating an insulating bat or insulation in other form thereon and snapping anelongated reflector on the flanges of the mounting plate. This automatically positions sockets in a proper arrangement to receive tubular heating elements therebetween.

A further object of the invention is to provide a practical construction for mounting radiant heat tubular heating elements in a room whereby the radiant energy from the heating elements is eiciently distributed and directed throughout the space that is to be heated, the mounting means for the heating elements being attractive in appearance as well as functioning efficiently.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully herein- Iafter described and claimed, reference being had to theI accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

K Figure-l is a perspective View of a portion of a room showing the radiant heat assembly typically located therein; y j

Figure 4 is an exploded perspective View of a portion of the room assembly shown in Figure l;

Figure 5 is a sectional view taken generally on the plane of line 5-5 of Figure 3; and,

Figure 6 is a transverse sectional view taken on the plane of line 6 6 of Figure 5 and in the direction of the arrows.

In Figure 1 in order to show the environment of the invention I have illustrated a room 10 having a oor, two

walls

12 and 14 together with a ceiling 16. At the junction of the walls with ceiling 16 the corner radiant heat assembly 18 is fitted. This assembly consists of a number of sections which are joined together in order to make the installation practical. One section is shown in FA1Ce Figure 4. Although a single length for the section 14 has arbitrarily been selected for illustration in Figure 4, the sections may be made of any length.

A section of the assembly 18 that typities the improved heating assembly includes a back mounting plate 22 having

sides

24 and 26 connected at right angles to each other by means of a short connecting strip 28. This connecting strip is adapted to be mounted in opposition to the cornerY of the wall and ceiling junction, leaving an air space void 30 therebehind primarily for the purpose of avoiding plastering iiush against the walls and ceiling.

A layer 28 of fire resistant insulation is applied to the back surface of mounting plate 22. The insulation is easily compressible to compensate for plastering or other irregularities of the wall and ceiling. Moreover, the insulating qualities of the xture are enhanced, permitting the use of higher heat. Although the insulation layer 27 may be applied in several ways, one is by flocking.

A rellector 32 is mounted between the

sides

24 and 26 of the mounting plate. It is preferably made of metal which is chrome-plated or otherwise made shiny on the front surface and painted black or otherwise made dark on the opposite side. The reflector is elongated and generally channel-shaped having a smoothly curved longitudinal trough 34 formed therein. Moreover, it is desired that the reflector be made of spring material in order to aid in fastening and holding it fastened to the mounting plate 22. In this regard, there are

means

36 and 38 at the longitudinal edges of the reflector 34 and at the corresponding longitudinal edges of the mounting plate 22 for holding the reflector 32 assembled with the mounting plate. The preferred means comprise on the edges of the reflector outwardly opening longitudinal and generally U-shaped in

cross section channels

40 and 42, respectively. They are formed by returning a portion of the edge of the reflector 32 and then returning another portion in the opposite direction. Flange 44 is formed at the outer edge of the side 24, while flange 46 is aryranged at the outer edge of side 26. These flanges are disposed in the same plane which extends from the ceiling 16 to wall 14 (Figure 2).

Flanges

44 and 46 are itted in the

channels

40 and 42 with the resiliency of the reiiector 32 being relied on to snap the reector in place.

Insulation 48 is'arranged in the space between reflector 32 and the mounting plate 22. The insulation may be spun glass, fibre glass or other commercially available insulating material. One longitudinal surface of the in sulation 48 is formed with a channel 50 that conforms to the shape of channel 34. `The three opposite surfaces of the insulation 48, that is, the

surfaces

51, 52 and 53 are at to t flush against the surface of the mounting plate 22. The

front surfaces

54 and 55 of the insulation 48 are generally coplanar so as to fit flush on the inner surfaces of the fastening means 36 and 38 which hold reflector 32 in place.

An elongated heating element 58 is disposed in parallel relationship to the reector 32 and is preferably located within the contines of the walls of the channel 34. The heating element may be selected from the group of available electric heaters or may be of special construction. The former expedient is preferred. Alternatively, heating element 58 may be used. It includes a ceramic bar 60 having a longitudinal heating element wire 62 extending through the center thereof. Bar 60 is encased in a metal tube 61 for strength and to prevent breakage. Tube 61 may be finished to enhance its appearance, as by painting or plating. A cylindrical contact 63 is fastened at one end of the wire 62 and is carried by the ceramic bar. A contact 64 is secured to the opposite end of the bar 60. These contacts are frictionally held in sockets,

"such ^as :socket 66 which consists of a ceramic'body 68 having 'a threaded shank 7 0 which passes through an.

aperture in hanger plate 74. A This hanger plate is secured at its inner end to one end of the reflector 32. The -threaded portion 70 of body -68 has an insulatingnut'76 threaded thereon in order to'hold the :socket in place. The body of the socket has a bore in it throughwhich an electric wire or wires '78 `pass in order to be connected with the pair of

spring clips

80 and 82 that are in .the

socket. These springs are disposed in side-by-side'relationship within a laterally opening groove 84 in the socket body and they frictionally hold one of the contacts, for examplecontact 63 within the socket. They also establish electrical continuity in the heater circuit inasmuch as the springs 8) and 82 are made of electricallyconductive material.

`When theheating elements are to .bestrun'g inside-by- 'side Yrelationship in lieu Tof the endsocket shown in Figure r5, a double-ended socket will be used, that is, one vhaving arslot .84 on one .side and an additional slot v34 on the .other side of the hanger plate, the latter slot being fitted with spring clips and electrically connected to the wire whereby the heating elements of two or more assemblies 18 are serially connected. Moreover, where the assembly is to be the end assembly, a cap S8 which frictionally engages by means .of flanges, the end of mounting plate 22, is used to close the end of the assembly.

In use after the installation as describedpreviously in a room, the radiant heat energy from the heating element is emitted directly into the room. The energy which is directed toward the reflector 32 strikes the shiny surface thereof and is directed into the room. .The insulation 48 together with the darkened rear surface of the reflector 32 aid in vproviding high insulating properties in the assembly.

However, there will be some heat conductedto the reflector 32. Also, the reflector will absorb some'heat and accordingly it will become a secondary emitter of radiant heat energy. In order to 4preventconductionvofaheat vfrom the reflectorv32 tothe mounting plate .22 through .the-fastening means 36 and 38, strips v90 and-92of insulating material are locatedfbetweenthe surfaces of flange 44 and the surfaces of the channel 40. Plate 92 is disposed between the surfaces of the flange 46 and those rof the channel 42. This insulation may be inthe form of glass tape, asbestos tape or otherrknown ltypes of insulating material which is thin. l

The foregoing-is considered as-illustrative only of the .principles 'of the invention. further, since numerous -inodifications and `changes will. readily occur `to those -askilled in the art, itisnot desiredto limit Athelinventionrto the exact construction and operation shown'and described,

land accordingly all suitable modifications and equivalents may be resorted to, falling within the scope 'of the invention as claimed.
