Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to, and the benefit of, U.S. Provisional Patent Application Ser. No. 61/524,736, filed on Aug. 17, 2011, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

1. Field
The aspects of the disclosed embodiment generally relate to the installation of building services, and in particular to mounting of wall and cover plates for electrical junction and outlet type boxes, air duct register covers and building controls such as thermostats co-planar with the building surfaces.
2. Brief Description of Related Developments
Walls, ceilings and other building surfaces contain numerous apertures for the installation of items such as electrical and audio-visual receptacles, controls and other devices and air ducts. Receptacles, as that term is generally used herein, include items such as electrical outlets and receptacles for switches, plugs, cable television, network, telephone, sound and other audio-visual wiring systems. Devices include items such as standard on-off switches; dimmer switches; timers; thermostats; motion, sound and other security sensors; security controls; speakers; video monitors; and other electrical and audio-visual controls. Air duct apertures include apertures for cold and warm air registers, air returns, ventilation fans and other air circulation systems. A common method for mounting such devices and covers involves cutting a rough aperture in the building surface material that is large enough to accommodate the receptacle, device or duct, finishing the building surface material utilizing paint, tile, or other standard construction practices, and concealing the rough aperture using a cover or device with dimensions that are greater than the aperture, which cover or device is attached such that the cover's or device's rear surface is flush with the finished building surface and the cover's or device's front surface protrudes from the finished building surface.
A variety of covers have been designed for common receptacles and control devices. The simplest form of cover is a single plate attached to the receptacle or control device utilizing one or more exposed screws. Another form of cover, intended to improve the aesthetic appearance, utilizes a backing plate mounted to the receptacle or control device utilizing one or more screws and a decorative cover that attaches to the backing plate without the use of screws.
Another common method of mounting devices and covers in wall apertures is by using a mounting flange with one surface that extends into the building surface aperture and a second surface that extends beyond the dimensions of the aperture parallel to the building surface.
The common element of each of the foregoing covers and devices is that the rear surface of the cover, device or device mounting flange is affixed flush to the finished building surface such that the front surface of the cover, device or device mounting flange protrudes some distance from the finished building surface.
FIG. 1 shows a three-dimensional perspective view of a typical prior art cover installation consisting of a receptacle 2 mounted to the junction box 1 with two screws 3. As shown in this example, the front surface of the junction box 1 is co-planar with the building surface 4 and the receptacle 2 protrudes a distance away from the building surface 4. This prior art one-piece cover 5 is attached to the receptacle 2 with two screws 6. The rear surface of the prior art cover 5 is co-planar with the building surface 4, while the front surface of the cover 5 protrudes away from the building surface 4.
There are many circumstances in which a highly-visible protruding cover or device is undesirable, including in a modern-style structure where clean lines and minimal features are desired or in a historic structure where receptacles, devices and ducts are required but are not consistent with the historic nature of the structure.
There have been attempts to allow covers to be mounted flush with the building surface. One attempt at mounting a receptacle and cover flush with the building surface is shown in U.S. Pat. No. 6,359,219, by Reid et al. However, the '219 patent relies on a custom recessed junction box, increasing its cost and precluding installers from using readily-available, inexpensive junction boxes. Also, the face of the junction box is recessed into the building surface, requiring the use of special installation techniques and precluding the standard practice in new construction of installing the junction box prior to installing the building surface. Furthermore, the '219 patent's wall flange consists of an “L” shape that requires the surrounding building surface be routed out to accept the junction box and wall flange in order for the front of the wall flange to be flush with the finished building surface. This makes the installation difficult and precludes the product's use with certain types of building surfaces that cannot easily be routed out, such as tile, stone, glass or metal. There is also no means of holding the wall flange in place while it is being affixed to the building surface, making it difficult to keep the wall flange level and even with the building surface during installation.
Another attempt at mounting a receptacle and cover flush with the building surface is shown in U.S. Pat. No. 6,931,794 by Burgess. However, one of the drawbacks of the '794 patent is that it does not address a means of protecting the flange area during installation and finishing.
Also shown in prior art patents are receptacle boxes and covers designed for mounting in a floor. Certain of these prior art devices, such as shown in U.S. Pat. No. 6,179,634, by Hull et al., are designed so that the cover is flush with the floor. However, due to the particular requirements associated with floor-mounted receptacles, including that they be watertight and sustain anticipated floor loads, these prior art devices are complicated and expensive. These characteristics limit the use of such devices in situations that do not require the floor mounted cover's special features.
Accordingly, it would be desirable to provide a flush-mount wall plate system that address at least some of the problems identified above.

DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENTS

Referring to FIG. 2, one embodiment of a wall plate system incorporating aspects of the present disclosure is generally designated by reference numeral 100. The aspects of the disclosed embodiments are directed to a wall plate system that includes a wall flange extrusion assembly 107 and one or more of a temporary cover 720 (shown in FIG. 7) and a final cover 820 (shown in FIG. 8). In the example of FIG. 1, the final cover 820 is shown installed in the wall flange extrusion assembly 107. The wall plate system 100 of the disclosed embodiments allows for installation of the wall flange extrusion assembly 107 in apertures in walls and other building surfaces in conjunction with standard or existing electrical junction, switch and outlet boxes, such that the front surface 821 of the final cover 820 is substantially co-planar, or flush mounted, with the exposed building or wall surface 4.
In the example shown in FIG. 2, the wall plate system 100 is mounted to or in a building surface 4, such as a wall. The building surface 4 in this example is constructed of a building material such as dry wall that is finished using a malleable compound to smooth the building surface 4. In the examples described herein, the malleable compound will be referred to as common joint compound, although any such suitable building material may be used. For purposes of the description herein, the building surface 4 will generally be referred to as a wall, although the aspects of the disclosed embodiments are intended to encompass any building surface in which a receptacle, such as for an electrical junction box 1, can be disposed, including for example, a ceiling or floor structure. For example, the aspects of the disclosed embodiments can also find application in the mounting of devices such as air ducts, thermostats, speakers, lighting controls, alarm sensors, infrared sensors, alarm system control panels, or any other device that is mounted in a wall, ceiling or other building surface where such devices may be located.
In the example of FIG. 2, a receptacle 2, in the form of an electrical outlet, and a wall flange extrusion assembly 107 are shown mounted in or attached to the junction box 1, using for example, mounting screws 3. The junction box 1, for purposes of the description herein, is generally a common type of junction box that is used to house and mount devices, such as electrical plugs, switches and other such devices. In one embodiment, the wall flange extrusion assembly 107 includes a mounting flange portion 115 and an extrusion member portion 118. The mounting flange portion 115 is configured to be aligned or disposed substantially flush with or on the building surface 4. The extrusion member portion 118 extends into an aperture or opening 10 in the building surface 4, in a manner or orientation that is substantially perpendicular to or from the mounting flange portion 115. A frame 119 of the extrusion member portion 118 defines an aperture 114. In one embodiment, a front edge or surface 109 of the extrusion member portion 118, in particular the frame 119, extends away from a front surface 117 of the mounting flange portion 115 by a pre-determined distance D2.
In one embodiment, the mounting flange portion 115 and extrusion member portion 118 of the wall flange extrusion assembly 107 are integrated into a single integrated component assembly 170 such as that shown in FIG. 3. Alternatively, the mounting flange portion 115 and extrusion member portion 118 of wall flange extrusion assembly 107 comprise two separate components that are connected during installation, such as the assembly 270 shown in FIG. 4.
In one embodiment, a final cover 820 is inserted into the aperture 114 of the wall flange extrusion assembly 107, generally referred to herein as the wall flange aperture 114. The front surface 821 of the final cover 820 is substantially co-planar with the front edge or surface 109 of the wall flange extrusion assembly 107 and exposed face 7 of the building surface 4.
In the exemplary embodiment of FIG. 2, the mounting flange portion 115 of the wall flange extrusion assembly 107 is blended into the building surface 4 using a finishing material 129, such as joint compound, so that the front surface 109 of the wall flange extrusion assembly 107 appears co-planar with the exposed face 7 of the building surface 4, as modified by the finishing material 129. In one embodiment, the mounting flange portion 115 of wall flange extrusion assembly 107 includes one or more openings 116 to aid in securing the wall flange extrusion assembly 107 to the building surface 4 utilizing, for example, the finishing material 129. In alternate embodiments, the wall flange extrusion assembly 107 is affixed to the building surface 4 by holding the wall flange extrusion assembly 107 in place using means such as screws, tabs, clips, or glue, while being permanently affixed to the building surface 4 using the appropriate affixing or finishing material based on the type of building surface 4.
The extrusion member portion 118 of the wall flange extrusion assembly 107 is sized to accommodate the receptacle 2. In one embodiment, the dimensions of the wall flange extrusion assembly 107, temporary cover 720 and final cover 820 are dictated by the dimensions of the receptacle 2 or device. For example, a common electrical receptacle 2 would require that the outside dimensions of the final cover 820 be a minimum of approximately 4.5 inches by 2.75 inches and that the aperture 822, shown in FIG. 8, in the final cover 820 be approximately 2.6 inches by 1.3 inches. As another example, a common air duct would require that the inside dimensions of the aperture 114 of the wall flange extrusion assembly 107 be approximately 7.5 inches by 11.5 inches. However, the aspects of the embodiments disclosed herein can be sized to fit any size or shape recessed junction box and any size or shape receptacle or control device. In addition, the aspects of the disclosed embodiments can be applied to recessed junction boxes that house multiple receptacles or devices.
While the junction box 1 referred to herein is generally described as a component separate from the wall flange extrusion assembly 107, in one embodiment, the junction box 1 is integrated with the wall flange extrusion assembly 107. In this embodiment, the wall flange extrusion portion 118 is of adequate length to accommodate a receptacle 2 or device. The integrated junction box 1 would be of a shape, and contain rear or side access points, consistent with common recessed boxes.
The wall plate system 100 of the disclosed embodiments can be made from any type of material commonly used in the industry to manufacture covers. The types of materials for the wall flange extrusion assembly 107 include, but are not limited to, plastics and ferrous or non-ferrous metals that are compliant with applicable building standards and codes. Materials for the covers 720, 820 or other device mounted in the wall flange extrusion assembly 107 can include, but are not limited to, plastics, ferrous or non-ferrous metals, or materials such as wood, stone or glass that are compliant with applicable building standards and codes.
The wall flange extrusion assembly 107, temporary cover 720 and final cover 820 can be manufactured using any suitable manufacturing technique commonly known in the industry such as, but not limited to, injection molding, stamping, welding, machining or cutting.
As is shown in FIG. 2, the mounting flange portion 115 extends away from the extrusion member portion 118, in a substantially perpendicular orientation, a distance D1. The distance D1, which can be any suitable distance, is generally sufficient to permit the wall flange extrusion assembly 107 to be securely attached to the building surface 4.
In the embodiment shown in FIG. 2, the front surface or edge 109 of the extrusion member portion 118 extends away from the front surface 117 of the mounting flange portion 115 in a direction that is substantially perpendicular to the mounting flange portion 115. In one embodiment, there is a distance D2 between the front surface 117 of the mounting flange portion 115 and the front surface 109. This allows the mounting flange portion 115 to be blended into the building surface 4 utilizing the finishing material 129 such that upon installation the front or exposed face surface 7 of the building surface 4 is or appears substantially co-planar with the front surface 109 of the extrusion member portion 118.
Referring to FIG. 3, in one embodiment, the wall flange extrusion assembly 107 comprises an integrated one-piece wall flange extrusion assembly 170. As shown in FIG. 3, the one-piece wall flange extrusion assembly 170 includes a mounting flange portion 325 and an extrusion portion 328, similar to the mounting flange portion 115 and extrusion member portion 118 shown in FIG. 2. In this example, the extrusion portion 328 is configured to be disposed in a substantially recessed manner in the mounting flange portion 325, as will be described herein.
In the example of FIG. 3, the mounting flange portion 325 includes openings 316 to aid in securing the mounting flange portion 325 to a building surface 4. Although the shape of the openings 316 shown in FIG. 3 are substantially circular, in alternate embodiments, the shape of the openings 316 can be any suitable shape, such as those shown in FIGS. 2 and 4.
In the embodiment shown in FIG. 3, the extrusion member portion 328, similar to the extrusion member portion 118 of FIG. 2, includes a front surface or edge 309 and a rear flange member 310, also referred to herein as a stop member. In one embodiment, a first end 311 of the rear flange member 310 extends substantially perpendicularly away from the inner side or surface 305 of the frame 319 of extrusion member portion 328, the frame 319 defining the extrusion aperture 114. The rear flange member 310 provides a stop for the temporary cover 720 shown in FIG. 7 or the final cover 820 shown in FIG. 8. The rear flange member 310 controls the depth of the temporary cover 720 or final cover 820 so that the front surfaces 721, 821 of the respective covers 720, 820 are substantially co-planar with the front surface or edge 309 of the extrusion member portion 328.
In one embodiment, the extrusion member portion 328 includes openings or recesses 111 in at least two locations on the inner side or surface 305 of the extrusion member portion 328. In the example of FIG. 3, the openings or recesses 111 are part of the rear flange member 310 for the purpose of receiving tabs 725, 825 shown in FIGS. 7 and 8, in the covers 720, 820, respectively, to secure the cover to the wall flange extrusion assembly 170.
In one embodiment, the wall flange extrusion assembly 107 has surfaces 112 extending into the aperture 114 of the extrusion 328, which surfaces 112 are referred to herein as the rear mounting flanges 112. The rear mounting flanges 112, which in this example extend outwardly or away from the rear flange member 310 into the aperture 114, permit the wall flange extrusion assembly 107 to be attached or secured to the junction box 1. In one embodiment, the rear mounting flanges 112 include openings or holes 113 that permit the wall flange extrusion assembly 107 to be affixed to a recessed junction box 1 utilizing screws 3 extending through the rear mounting flanges 112 and into threaded holes common to all recessed junction boxes, thereby holding the wall flange extrusion assembly 107 in the proper position while the wall flange extrusion assembly 107 is affixed to the building surface 4. In an alternate embodiment, the rear mounting flanges 112 are sized and located to permit the wall flange extrusion assembly 107 to be affixed to an air duct (not shown), thereby holding the wall flange extrusion assembly 107 in the proper position while the wall flange extrusion assembly 107 is affixed to the building surface 4. In one embodiment, the holes 113 in the rear mounting flanges 112 are threaded holes such that the receptacle 2 or other device can be affixed to the wall flange extrusion assembly 107 rather than to a junction box 1.
Referring to FIG. 4, in one embodiment, the wall flange extrusion assembly 107 comprises a two-piece wall flange extrusion assembly 270. In this example, the two-piece wall flange extrusion assembly 270 comprises a mounting flange member 424 and an extrusion member 427 that are coupled together during installation. The extrusion member 427 is configured to be slidingly engaged with or affixed to the mounting flange member 424 at varying distances D3 from the front surface or first end 409 of the extrusion member 427. In the embodiment shown in FIG. 4, slots 426 in the mounting flange member 424 slidingly engage the mounting posts 428 on the extrusion member 427. The mounting posts 428 align with and insert into the slots 426. The slots 426 and mounting posts 428 permit the mounting flange member 424 to be affixed to the extrusion member 427 such that the distance D3 from the first end 409 of the extrusion member 427 and the front surface 417 of the mounting flange member 424 substantially match the approximately thickness of the finished building surface material.
In one embodiment, referring to FIG. 5, the extrusion member 427 has a frame 471, similar to the frame 119 of FIG. 2, with side portions 472, 473, 474 and 475. The side portions 472, 473, 474 and 475 of the frame 471 define an aperture 414. The mounting flange member 424 defines an aperture 514 (shown in FIG. 6) that substantially aligns with aperture 414. The apertures 414 and 514 generally comprise aperture 114 referred to in FIGS. 2 and 3. The frame 471 also includes a front surface or edge 409 and a rear flange member or stop member 410, substantially the same as front surface 309 and rear flange member 310 of FIG. 3. The rear flange member 410 is disposed along the second end or rear edge 332 of each side portion 472, 473, 474 and 475 of the frame 471. As shown in FIG. 5, the rear flange member 410 is substantially continuous along the second end 332 of each of the side portions 472, 473, 474 and 475 of the frame 471.
In one embodiment, the extrusion member 427 includes recesses 111 that are disposed in an outer facing portion of each of the side portions 473, 475. The recesses or openings 111 can be used for mounting the temporary cover 720 or final cover 820 to the extrusion member 427.
In the embodiment shown in FIGS. 4 and 5, mounting flanges 112 extend from the rear flange member 410 on side portions 473, 475 of the frame 471. The mounting flanges 112 include the mounting holes 113 for attaching the extrusion member 427 to, for example, a junction box 1, as is shown in FIG. 2.
Referring to FIG. 5, in one embodiment, the extrusion member 427 includes mounting posts 428. The mounting posts 428 are disposed on a rearward side 401 of the extrusion member 427 in a substantially orthogonal manner, or so that each mounting post 428 extends away from the extrusion member 427. In the embodiment shown in FIG. 5, the extrusion member 427 includes four mounting posts 428. In alternate embodiments, any suitable number of mounting posts 428 can be included, including more or less than four. For example, it could be advantageous to use only two mounting posts 428, the two mounting posts 428 being diagonally opposed to one another.
As shown in FIG. 5, each mounting post 428 is disposed in a corner region of the extrusion member 427. In the embodiment shown in FIG. 5, each mounting post 428 is a distance D4 from the corner 402 of the extrusion member 427. In one embodiment, this distance D4 can be in the range of approximately 0.25 to 0.5 inches, depending upon the size of the extrusion member 427. In alternate embodiments, the distance D4 can be any suitable distance including less than 0.25 inches or greater than 0.5 inches. In one embodiment, a length L1 of each mounting post 428 is in the range of approximately 0.5 to 1.5 inches. In alternate embodiments, length L1 of each of the mounting posts 428 can be any suitable length. In addition, the mounting posts 428 can be either permanently affixed to the extrusion member 427 or may be removably affixed to the extrusion member 427 by threading one end of the mounting posts 428 and including threaded holes in the extrusion member 427 located and sized to accept the mounting posts 428 or by affixing the mounting posts 428 to the extrusion member 427 using a snap-fit type connection. The mounting posts 428 are configured to be removably received or disposed in slots 426, shown in FIG. 4, in the mounting flange member 424 of the two-piece wall flange extrusion assembly 270.
Referring to FIG. 6, in one embodiment the mounting flange member 424 includes slots 426 which slots align with the mounting posts 428 of the extrusion member 427. In this example, the mounting flange member 424 can be positioned and secured to the building surface 4, as is generally described herein. The extrusion member 427 can then be slidingly engaged with the primary mounting flange member 424. The sliding engagement of the mounting posts 428 in the slots 426 allows the extrusion member 427 to be positioned at any desired distance from the primary mounting flange member 424. In one embodiment, when the desired position is achieved, the mounting posts 428 can be secured in the slots 426 using, for example, a fast-acting glue. Alternatively, the mounting post 428 and slot 426 are configured for a friction-type engagement, to hold the extrusion member 427 in the desired position.

The side surfaces 823 of the membrane extend substantially perpendicularly from the rear surface 824 of the membrane 830.
In an embodiment for use with self-contained devices such as thermostats, as shown for example in FIG. 15, the temporary cover 1020 device 1120 are configured and sized to fit inside the aperture 914 of the wall flange extrusion assembly 907 as is generally described herein with respect to FIGS. 2-8. The front face 1021 and 1121 of the temporary cover 1020 and device 1120, respectively, are configured to align with the front surface 909 of the wall flange extrusion assembly 907.
In an alternative embodiment for use with air ducts, as shown for example in FIG. 16, the cover 1420 comprises a membrane that has a plurality of holes or slots 1422 generally consistent with commonly available air duct register covers. The temporary cover 1320 and air duct register cover 1420 are sized to fit inside the aperture 1214 of the wall flange extrusion assembly 1207 as is generally described herein with respect to FIGS. 2-8. The front face 1321 and 1421 of the temporary cover 1320 and air duct register cover 1420, respectively, are configured to align with the front surface 1209 of the wall flange extrusion assembly 1207.
