A flush-mount wall plate system for mounting in a building surface includes a wall flange extrusion assembly with a mounting flange portion and an extrusion member portion. The extrusion member portion has a frame defining an aperture, with a front edge of the frame extending away from a front surface of the mounting flange portion by a pre-determined distance. A cover is inserted into the aperture with a front surface of the cover being substantially co-planar with the front edge of the extrusion member portion and the building surface.
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.
BACKGROUND1. 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.
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.
