A draft-free electrical receptacle housing that reduces and preferably eliminates crevices and air passages through it so as to eliminate air flow currents passing through the same and thence into a room in which the electrical power receptacle communicates as disclosed.

Description
0~
This invention relates to a draft-free electrical power receptacle housing.
In the prior art there are various electrical housings or electrical receptacle boxes which are used in co-operation with electrical receptacles so as to terminate the receptacle to electrical wiring in and for energizing the receptacle accordingly.
It is known that such prior art electrical receptacle boxes are generally mounted on wooden studs or joists (normally 2' x 4's) that are commonly made of wood. The electrical boxes are generally of stamped galvanized steel and have knockout for the accommodation and passage of electrical wires into them. They are also commonly provided with holes in the side and rear walls so that nails can be conveniently passed through the same and used as the anchoring or fastening means for securing the receptacle boxes ~o the wooden joists.
Drywall or other wall covering is placed over the wooden joists and then the electrical receptacle is placed into the box and mounted by screws and a wall face plate is placed thereover. Because of the knockouts and the holes in the electrical receptacle boxes and the slits or openings between the face plate and the receptacle itself there are fissures or crevices which allow the free passage of air currents through the receptacle box into a heated or air-conditioned room into which the electrical receptacle faces. These free-flowing currents tend to reduce tha heating and cooling efficiency and increase energy costs.
With these objects in mind, the invention contemplates a draft free electrical receptacle housing that reduces and preferably eliminates all crevices and air passages therethrough so as to eliminate air flow currents passing through the same.
The invention achieves a draft-free electrical power receptacle housing for use in combination with an electrical receptacle and a face plate mating therewith, the housing comprising, a box-like member defining a plenum, the member having a bottom extending, unitarily, into vertical sides and ~0~1~8 ends which respectively merge one with the other and then extend into a common margin as the perimeter of the plenum, the margin intersecting and coincident with a plane that is parallel to the bottom, each of the sides and ends terminatin~
at a flange, each flange being integral with its adjacent side or end and lying in the plane, the flanges disposed so as not to overlay the prolongation of the plenum defined by the perimeter of the member, each flange deining at least one means for receiving an anchoring means; and a surround defining a first means for receiving an anchoring means and including means for matingly urging the surround over the sides and ends of the member whereby the member and surround are relatively held in fixed relation.
The invention will now be described by way of example in reference to the figures in which:
Figure 1 is an assembly view of the invention.
Figure 2 is a side longitudinal section view of the invention in application.
Referring to figure 2, the draft-free electrical receptacle housing is generally shown as 10, the same being mounted in a wall 30.
Referring to figure 1, in actuality, the draft-free electrical power receptacle housing 10 includes a box-like member 12 and a mating surround 14. As clearly seen in figures 1 and 2, -the box 12 consists of a flat bottom 16, flat ends 17, and 18 wherein end 18 is being inclined relative to the bottom, and opposite vertical flat side walls 19. The side walls 19 and flat bottom 16 and ends 17 and 18 are unitarily formed so that -there are no apertures or fissures therein although. What is not shown is that each of these surfaces may provide punched dimples or "knock-outs" which may be "knocked out" to provide for the passage of electrical wires or cable 40, as indicated in figure 2. In that respect, figure 2 shows that a knock out has been removed from the end 17 to dispose and define wire passing aperture 17'. The respective surfaces 17, 18, and l9 terminate at a common frontal margin 21, which lies in a plane parallel to that of . ', .' ' '`'' - - ' - .
0~8 the flat bottom 16. The margin 21 as well acts as the perimeter for the plenum 20 which is defined by the box 12.
The margin generally shown as 21 also has each of the adjacen~
surfaces 17, 18, and 19, folding over into a flange 17" or 18 or 19'l with each flange de~ining apertures 22 therein which act as means for accepting fastening means (nails and the like) so that the box 12 may be affixed to the joist or stud 11~ The flanges lie within the plane of the margin 21. In order to facilitate this attachment and for encouraging sealing of the outside perimeter of the box with the surrounding wall 30, a surround plate 14 comprises a flanged flat surface 25 defining a plurality of anchoring apertures 26 and defining a central 27 opening whose perimeter is coincident with the external perimeter of the box 12 so as to matingly engage therewith. The perimeter of the aperture 27 defines a plurality of vertical flanged surfaces or pieces 28.
Preferably there are four in number and these provide biasing means for urging against the respective surfaces 17, 18, and 19 whereby to relatively constrict the box 12 and the surround 1~.
In application, nails 32 are used to extend through the apertures 26 and to secure the surround 14 onto the stud 11.
A vapour barrier 50 of film material generally covers over the surround and then the drywall indicated as 30 is placed over the wall with an accommodating aperture shown as 12' cut : therein so as to accommodate the box 12. The box 12 is pushed into the aperture 12' and into the receiving opening 27 of the surround 14 and the box 12 is thereby held sandwiching therebetween as a result of the flanges 17", 18" and 19", the drywall 30 and the vapour barrier 50 and creating an air-tight seal therebetween. Securing means, such as by screws 42, are passed through the apertures 12" and the drywall 30 into receiving apertures 14' in the surround 14.
In a conventional manner, the electrical receptacle 35 is mounted into the plenum 20 while electrical wires 35 are passed through the aperture 17' and connected to the receptacle 35 as shown in figure 2. Any remaining space ~L29~
between the cable 40 and the aperture 17' is sealed off ~,7ith a caulking compound 39.
After installation and wiring 40 to the electrical receptacle 35, a covering wall plate 36 is attached to the receptacle 35 in a conventional manner.
: In this fashion, the novel draft-free electrical receptacle housing is achieved.
