Abstract:
A thermostat wire holder is used behind a portion of wall covering to hold a thermostat wire next to a hole in the wall covering where a thermostat will be located. The wire holder insulates the hole in the wall covering so that the air inside the wall does not influence the thermostat reading. The holder is generally V-shaped when installed on a stud and includes front and rear support members.

Description:
The present invention relates to a thermostat wire holder device which is fitted around a wooden or metal wall stud in a building structure to retain a thermostat wire and thermostat in fixed insulated relation. 
     Normally when installing a thermostat wire or wire bundle between adjacent wall studs in a building structure, the terminating end of the wire or wire bundle is simply wrapped around a single nail temporarily or permanently attached to a wooden or metal wall stud during construction in the general location where an interior wall thermostat or other electrical device is to be permanently located. The wire normally consists of a single bundle of multiple electrical wires usually from about 2 to 12 individual electrical wires which are used to contol a thermostat or other electrical devices. Some are used for control and some are used to make electrical connection to various electrical devices. The wire or wire bundle may extend to a telephone jack, a television jack, a cable jack or a doorbell, or other electrical devices located within the building interior. 
     Such wiring installation is usually done after the interior wall studs are erected and prior to erecting the interior wall covering materials such as dry wall paneling, plaster, wooden wall paneling and other wall coverings. After the wall panels are installed, the precise location of the thermostat wire or wire bundle behind the covered walls is not easily determined, especially if the wall studs are covered on one or both sides by the wall covering materials. Often locating the single wire or wire bundle requires so-called “fishing” for the wire end in the hollow interior space between studs and bringing the wire outwardly into the room interior to be exposed therein for connection to the wall thermostat or other electrical device. The wire or wire bundle may be removed from its nail support or be left thereon as desired. The wire must normally be dragged through an aperture in the wall which in some cases may be excessively large and must be repaired. The wire and its surrounding space within the wall interior is essentially uninsulated which can and does adversely affect temperature settings and readings of the thermostat, for example. The lack of insulated backing and support for the control wire often results in poor and inaccurate performance of the thermostat over its controlling life within the building structure. 
     Accordingly, an object of the present invention is directed toward providing an insulating and support back plate for the thermostat wire and thermostat within a building structure for accurate and precise controlling of a thermostat for its insulated mounting in the interior of a building structure. 
     A further object of the present invention is to provide a foldable economical thin plastic mounting plate for a thermostat wire or wire bundle connected to and at least partially around a wooden or metal wall stud which has combined insulating and supporting characteristics for the wire and thermostat. The mounting plate may be easily folded from a flat stored sheet into a generally V-shaped or Z-shaped configuration for the wire holder device for its attachment to an upright wooden or metal wall stud for fixedly mounting the wire within an interior wall space for its ready interconnection to a wall thermostat or other electrical device in an interior wall-mounted location. 
     A still further object of the present invention is to provide a thin durable foldable insulating back plate for supporting a thermostat wire and thermostat which plate retains the wire in fixed relation between wall studs and attached to one stud in desired location for easy location of the wire end portion and providing insulation to the wire area immediately behind the wall covering once it is applied or mounted to provide interconnection to a wall thermostat or other wall-mounted device. 
     The subject interior backing plate for the wall space provides both insulating and supporting features to the wire mounting and adjacent hollow space surrounding the wire interiorly of nearby adjacent wall studs. The wire may be readily located and found within the wall after wall coverings are mounted or installed on interior wall studs. The plate has observation openings in one folded portion of the plate for observing the wire location and its end portion for ready connection to a wall thermostat or other device. When in its folded-over mounting relation, the plate has punched-out or recessed areas for punching out wire-receiving holes therein for passage of the wire therethrough. The plate also serves as an air-sealing device around the wire. 
    
    
     In the attached accompanying drawings, the designated views of the wire holder show the device in its original stored flat relation before its folding into a generally V-shaped or Z-shaped configuration, and after such folding and installation within an interior wall of a building structure.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With regard to FIG. 1 of the drawings, the retention plate  10  preferably consists of a flat foldable foamed plastic material such as relatively thin foamed polystyrene or polyethylene material or other comparable plastic material. The plate  10  has preferred dimensions of about 6 by 12 inches and a thickness of about {fraction (1/16)} inch. Other foamed plastic materials may be used to comprise the plate; however, it should be sufficiently thin and strong to hold the thermostat wire and thermostat when mounted in fixed relation and so as not to adversely affect the planeness of facing surfaces of plural adjacent wall studs. The edge portions  10   a  and  10   b  of the plate when folded from its flat stored condition can be readily stapled, nailed or screwed to a single wooden or metal wall stud attached by the said edges. The major interior portions of the plate are then located interiorly between adjacent studs within the hollow space therebetween. 
     FIG. 2 shows the plate in folded non-planar configuration with its edge portions  10   a  and  10   b  attached to the single vertical wall stud. The plate edges are attached so that one medial portion of the plate extends over and across the interiorly-facing surface of the stud. The other edge portion of the plate is attached to and against the transversely-facing interior portion of the stud. The wire or wire bundle  12  may be attached to one or more stud members of the wall such as by stapling, nailing or screwing, and brought forwardly through the pair of smaller apertures  10   f  and  10   g  which are spaced apart in horizontal alignment when the plate is folded into the generally V-shaped configuration as shown in FIGS. 2 and 3. 
     The V-shaped structure of the device when folded provides adequate wire supporting strength to the device for long-term retention of the wire  12  in fixed relation as well as insulation to the plate openings through which the wire is passed. The interior space behind the wall-mounted thermostat when installed is thus well insulated by the back wire-mounting plate. The plate serves a dual function of wire retention through a wall when the wire is installed as well as insulation to the enclosed wall space in and behind the thermostat whereever installed. The plate also serves to insulate around the wire access openings where formed. The room interior may be more accurately thermally controlled by the thermostat for its improved operation and control. The plate provides edge surfaces for attachment to a single stud which may be either wood or metal. The edge portions  10   a  and  10   b  of the plate are folded by a pair of parallel score lines  10   c  and  10   d  located generally equidistant from the terminating edges of the plate for their folding into angular relationship from the plane of the flat plate. The edges are readily accessible for folding into desired attachment members. The plate is easily usable in both right and left hand mounting between adjacent single studs. The right-hand portion of the plate is folded into an angle of about 45 degrees from the plane of the flat plate for stud attachment. The left-hand portion of the plate as shown in FIG. 1 is folded into a right angle for attachment to the single stud  11 . The near-central scored fold line  10   e  of the plate is located off center to form the device with slightly dissimilar intermediate facing surfaces. Thus, the plate may be folded into a V-shaped form having facing surfaces of different lengths. The left-hand facing surface of the plate is exposed interiorly of the room and wall coverings facing the room interior area for thermostat interior wall mounting. 
     A pair of small apertures or indentations  10   f  and  10   g  are formed in a medial region of the plate  10  in axial alignment. The small apertures or indentations may be actual small openings having a similar diameter of about ⅛ inch or comprise slightly indented areas or markings where the thermostat wire or bundle  12  may be pushed through the plate for its retention thereby. The wire  12  then extends through two aligned holes  10   f  and  10   g  in the plate as shown in FIG. 2. A pair of larger apertures or openings  10   h  and  10   i  having a diameter of about ⅝ inch are preferably formed in the rearward side of the plate when folded such as near to smaller aperture  10   g  in alignment therewith to provide observation holes or viewing ports for wire mounting through the plate. Such apertures  10   h  and  10   i  provide lines of sight for locating wire  12  and its free end  12   a  when the wire is inserted in and through the plate from the backside. The small apertures  10   f  and  10   g  fit tightly around the wire  12  to provide air seals to the wire areas. 
     The plate may be easily and simply installed in the wall in selected areas during construction of the building and subsequent installation of control wires such as thermostat wire plus other types of electrical wiring to facilitate their improved installation and operation.
