INVEN FRAN K J.SOUKEV NKZHOLAS E.M- DOUGALL WKQM ATTORN EY WW United States Patent 3,260,835 RADIANT HEATING SYSTEM Frank J. Souitey, 255 S. Third St., and Nicholas E. McDougall, 834 Oneida St., both of Fulton, N.Y. Filed Feb. 4, 1964, Ser. No. 342,401 3 Claims. (Cl. 219-213) This invention relates to electric radiant heating, and more particularly to radiant heating panels therefor.
The practice of providing a ceiling comprised of panels of standard size suspended from an overhead supporting structure such as floor joists, roof members, and in some cases a high ceiling is well known, as well as the use of radiant heat derived from electrical resistance units. However, it has been the practice to provide such radiant heating units as a part of a relatively permanent construction wherein difficulty is had when replacement or modification as to the number and location of such units is desired.
The present invention is directed to an electrically energized radiant heating system, wherein a single panel of standardized construction is readily included in a panel type ceiling construction, either singly or in pairs. The construction is such that when the panels are employed in pairs, a series connection of the heating units of a pair of panels is readily elfected. Thus radiant heating panels of a single standardized construction adapted for connection to a 110 volt source of supply, are readily adapted for use on a 220 volt source when paired. The invention further has to do with the construction of the heating panel whereby connections are made by simple plug-in connectors, the use of which automatically establishes the circuit for the supply voltage to be used. The invention further has to do with provision for connecting the panels to a source of supply and in pairs in a manner such that the panels may be quickly installed, removed, replaced, or added to, the necessary connections being effected by simple plug-in operations. A further feature of the invention is the provision of a panel wherein the radiant heating circuit is automatically opened for series connection with a companion panel by a mere plug-in operation.
The above and other novel features of the invention will appear more fully hereinafter from the following detailed description when taken in conjunction with the accompanying drawings. It is expressly understood that the drawings are employed for purposes of illustration only and are not designed as a definition of the limits of the invention, reference being had for this purpose to the appended claims.
In the drawings wherein like reference characters indicate like parts:
FIGURE 1 is a sectional view of a ceiling installation with radiant heater panels installed;
FIGURE 2 is a perspective view of two adjacent radiant heater panels connected in series;
FIGURE 3 is a wiring diagram;
FIGURE 4 is a fragmentary enlarged sectional view through a radiant heating panel;
FIGURE 5 is a side elevational view of a panel socket;
FIGURE 6 is a side elevational view of a plug adapted for use with the socket;
FIGURE 7 is a bottom view of the socket of FIG- URE 5;
FIGURE 8 is a bottom view of the plug of FIGURE 6, and
FIGURE 9 is a perspective view of conductor parts within the socket of FIGURES 5 and 7.
Referring to the drawings, there is shown in FIGURE 1, a fragmentary section through a ceiling construction wherein ceiling panels 20 are supported in a suspended manner from the flooring or other structure above. As
'70 lying in a common plane,
3,260,835 Patented July 12, 1966 ice shown, a wall 24 is provided with a plate 26, over which is laid a flooring 28, having spaced joists 30. Supported from the wall on angle members 32, and inverted T sectioned members 34 suspended from. the floor or joists by wires or links as indicated at 36 and 38, are the ceiling panels 20. While some or all of the panels may be radiant heating panels, it will be understood that such panels may be interspaced with ordinary panels of a standard type having no provision for heating, or with panels having lighting fixtures for example.
Along the plate and above the ceiling panels, is a conduit 40 for a heating power supply which in practice may be a circuit 42 capable of operating on 220 volts. Such conduit is provided with frequent outlet boxes 44 having plug-in receptacles 46, the boxes being disposed preferably at intervals corresponding to the width of the panels. It will be understood that the spacing between angle members 32 and the T members 34 will be such as to accommodate panels 20 of a standard size, and that T members similar to members 34 and angle members 32 may also be provided at right angles to those shown to provide square or rectangular flanged frames of a size to receive and support the panels of a standard size. It will also be understood that in the usual practice, the supporting T and angle members 34 and 32 are installed at proper spacings to receive the panels after which each panel is inserted upward through the rectangular opening of the supporting members where the panel is to rest, and the panel is thereafter oriented and lowered so as to rest fiat upon the flanges of the members 32 or 34 in forming the ceiling construction.
Each of the heating panels comprises a unit adapted for radiant heating of a prescribed wattage when operating on 110 volts. In order that panels may serve in a 110 volt supply circuit, or be used in conjunction with a second panel of identical construction in a 220 volt supply circuit, by connecting two panels in series, each panel comprises an identical resistance heating unit generally indicated at 60. Each panel is also provided with a male plug 62 at one end, adapted to be connected to a receptacle 46 by a flexible two conductor cable 64 having a suitable plug 66 and receptacle 68 at its oppositeends. Such cable is of a length such that the connections may be made between a receptacle 46 and plug 62 prior to positioning the heating panel in its ultimate position of rest in the supporting frame members. The cable supplies the radiant heat panel with power from the power circuit 42.
The two conductor cable 64, for use with 220 volts, and for supplying two panels connected in series will in practice have its plug 66 provided with flat contact blades as indicated in FIGURE 3. A similar cable 64 for supplying a single panel from 110 volts will have its plug 66 provided with two blades lying in spaced parallel planes.
Each radiant heater panel may have a heavy heat insulating and preferably fire resistant panel 80, on the underside of which is positioned a heat reflective sheet 82, and below which are two spaced glass panels 84 and 86, between which is an electrical resistance heating grid 60 of a suitable wattage when energized by a source of power supply of 110 volts. The panel, sheet and glass plates may be secured together in any suitable fashion and may have a rectangular inwardly facing channel sectioned frame 88, of sheet metal, stainless steel or other suitable material. The glass panel 86 may have a frosted or irregular under surface 87, if desired.
At one end of each panel on the back or top side is postioned a plug 62, and at the other end is a plug-in receptacle 90. The receptacle may be of the type shown in FIGURES 5-9, if desired. As shown, the receptacle 90 comprises a housing 92 of insulating material which may be aflixed to the panel 80 in any suitable manner. The housing 92 is provided with an opening 94 to receive a plug 96 having spaced electrical contact pins 98 connected to a two wire flexible cable 100 having a receptacle 68 for making contact with the plug contacts 69 of the plug 62 of the second panel.
Mounted within the housing in suitable recesses are spaced electrical contact members 102 and 104. Each contact member comprises a transverse conductive member 106 having an aperture 108 in which is aflixed a contact sleeve 110 of a internal diameter to receive a contact pin 98. The transverse member 106 is provided with an integral rearwardly bent portion 112 having a binding post screw 114, and a forwardly extending foot portion 116 lying flush with the inside wall of the plug receiving opening 94. A transverse slot 118 is formed in the housing member beneath the foot portions 116 of the contact members 102 and 104. Disposed in the slot 118 is a conductor blade 120 adapted to contact the underfaces of the foot portions 116, under pressure of a leaf spring 122 aflixed to the center of the blade as by a counter-sunk rivet 124. The free ends 126 and 128 of the spring slide on the bottom of the slot 118, and urge the blade 120 upward in the slot into electrical contact with 'both foot portions 116 to provide an electrical connection between the members 102 and 104.
Disposed between the foot portions 116 is a second slot 130 in the wall of the opening 94, extending inwardly of the opening, and across the slot 118. The plug 96 is provided with a camming rib or tongue 132 adapted to ride in the slot 130 when the plug is inserted into the opening 94, and the camming end 134 of the tongue is adapted to engage the blade 120, to depress the blade away from the contact feet 116, against the urge of leaf spring 122. Thus upon insertion of the plug 96 so that the contact pins 98 are received in the respective contact sleeves 110 to effect a connection therewith, the shunt connection between the contact members afforded by the blade 120 is broken.
To prevent the unauthorized removal of the plug 96, a setscrew 136 in the side wall of the housing may be provided, the end of which may be seated in the recess 138 in the plug, when the plug is inserted into the housing opening 94. Such setscrew may be of the typical Allen head type if desired.
It will be seen from FIGURES 2 and 3, that in each radiant heat panel, the heating grid resistance 60 is connected to One of the blades 69 of plug 62, and to one of the contacts 102 and 104 of plug-in receptacle 90, while the other blade 69 of plug 62 is connected to the other of the contacts 102 and 104, as by a lead 140.
In practice, two types of flexible cables 64 may be supplied, one with a plug 66 having contact blades lying in spaced parallel planes for use when the circuit 42 is operating at 110 volts, and the other with a plug 66 having spaced flat blades lying in a single plane for use when the circuit 42 is powered at 220 volts, it being understood that corresponding receptacles 46 will be employed. The flexible cables 100, being supplied with plugs having round pins 98, restricts the use of such cables to interconnecting two panels where the line 42 is powered at 220 volts.
It will be seen that each panel, whether to be used singly or in pairs is identical, and that when the panels are paired, the proper series circuit is automatically established by the mere insertion of the plug 96 into the plug-in receptacle 90.
It will appear that in practice, the shunting blade, and its automatic operation may be eliminated, if desired, from the plug-in receptacle 90, in which case a plug such as 96 having its contact pins connected together may be supplied for insertion into the plug-in receptacle 90 to complete the connection between the contact members 102 and 104. A single panel of this type may thus be prepared for use in a 110 volt system, by employing such a plug, or the second panel of a pair of panels connected together by a cable 100, may have its circuit completed by employing such a plug in the plug-in receptacle of the second panel.
It will be seen from the foregoing, that a panel ceiling construction can readily be provided with as many radiant heating panels as desired and by reason of the flexible cables and plug-in connections employed, the radiant heating panel can be inserted in place, or substituted for non-heating panels about as readily as non-heating panels are placed in position. By providing flexible cables of adequate length, connections for each panel may be made as necessary before placing the panels in final position in the suspended supporting frame work. The connections are made without the use of tools. Where panels are supplied for 220 volt use, one panel of each pair may be supplied with a cable with its plug 96 locked in place in the plug-in receptacle 90, by the setscrew 136, so that error in installation and completing the connections are minimized. Although a two wire circuit 42 has been shown, which may be either a volt circuit using panels all connected in parallel or which may be a 220 volt circuit using pairs of panels connected in series, and the pairs being connected to the 220 volt circuit in parallel, it will also be understood that the 220 volt circuit may also have a third wire connected to ground, and acting as a neutral, so that single panels connected in parallel can be connected to the neutral and one of the other wires, and other single panels connected in parallel can be connected to the neutral and the other wire. On the other hand where pairs of panels are connected in series and connected to the 220 volt circuit the third neutral wire or ground wire if provided, may be connected to the metal frame 88 of the panels or the reflector 82, or to the supporting grids 32 and 34, or any or all. The former connection to the frame may be effected by a three prong plug and receptacle and use of a three wire cable 64, the plug 62 having a third contact connected to the metal frame 88, or to the reflector 82 or both. Similarly the cable 100 may be three wire, one of which would carry the ground from one panel to the other of the pair connected in series. In such case the receptacle 90 and plug 96 will have a third contact and pin for effecting the connections.
It is well known that comfortable conditions within a room may be attained from radiant heat with air temperatures well below that generally considered normal. The system set forth provides for ready change as to the number of radiant panels to be used, it being merely necessary, to substitute radiant panels for non-radiant panels as desired and effect the necessary plug-in connectrons. Such changes are readil made without in any way affecting the building structure.
While a single form of the invention has been illustrated and described, and variations indicated, it is to b understood that the invention is not limited thereto. As various changes in the construction of various features and the arrangement may be made without departing from the spirit of the invention, as will be apparent to those skilled in the art, reference will be had to the appended claims for a definition of the limits of the invention.
