What is claimed is:
This application claims priority from commonly-assigned U.S. Provisional Patent Application Ser. No. 60/808,190, filed May 24, 2006, having the same title as the present invention, the entire disclosure of which is hereby incorporated by reference.
1. Field of the Invention
The present invention relates to load control devices for controlling the amount of power delivered to an electrical load, specifically a traditional-style dimmer switch having a faceplate adapter to allow the dimmer switch to be mounted with a designer-style faceplate.
2. Description of the Related Art
A conventional wall-mounted load control device is mounted to a standard electrical wall box and is coupled between a source of alternating-current (AC) power (typically 50 or 60 Hz line voltage AC mains) and an electrical load. Standard load control devices, such as dimmers and motor speed controls, use one or more semiconductor switches, such as triacs or field effect transistors (FETs), to control the current delivered to the load, and thus, the intensity of the lighting load or the speed of the motor. The semiconductor switch is typically coupled in series between the source and the lighting load. Using a phase-control dimming technique, the dimmer renders the semiconductor switch conductive for a portion of each line half-cycle to provide power to the lighting load, and renders the semiconductor switch non-conductive for the other portion of the line half-cycle to disconnect power from the load.
Wall-mounted load control devices typically include a user interface having a means for adjusting the power delivered to the load, such as a linear slider, a rotary knob, or a rocker switch. As shown in
It is desirable to gang together the traditional-style dimmer switch 10 and the designer-style dimmer switch 20, i.e., to install the traditional-style dimmer switch and the designer-style dimmer switch next to each other in a two-gang wallbox. Prior art faceplates, for example, the faceplate 30 shown in
Therefore, it is desirable to gang together the traditional-style dimmer switch 10 and the designer-style dimmer switch 20 using a multi-gang designer-style faceplate 40 as shown in
According to the present invention, a faceplate adapter for a load control device comprises a front surface, an adapter opening in the front surface, and an attachment post. The front surface defines a first area substantially the same size and shape as a faceplate opening of a designer-style faceplate. The adapter opening defines a second area substantially the same size as a faceplate opening of a traditional-style faceplate. The attachment post allows the adapter to be secured to the load control device.
The present invention further provides a traditional-style load control device having a faceplate adapter to allow the load control device to be mounted with a designer-style faceplate. Specifically, the load control device comprises a designer-style faceplate having a first opening defining a first area, an adapter having a periphery defining the first area, and a user interface. The adapter is operable to be received in the first opening of the designer-style faceplate and has a second opening defining a second area larger than the first area. The user interface is operable to be received in the second opening of the adapter. Preferably, the load control device further comprises a yoke for attaching the load control device to an electrical wallbox. The yoke comprises an attachment opening and the adapter comprises an attachment post operable to be received in the attachment opening to secure the adapter to the yoke.
Other features and advantages of the present invention will become apparent from the following description of the invention that refers to the accompanying drawings.
The foregoing summary, as well as the following detailed description of the preferred embodiments, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings an embodiments that is presently preferred, in which like numerals represent similar parts throughout the several views of the drawings, it being understood, however, that the invention is not limited to the specific methods and instrumentalities disclosed.
The dimmer switch 100 further comprises a user interface 118. The user interface 118 has a toggle button 120 to allow a user to toggle a connected lighting load (not shown) between on and off. The user interface 118 also includes an intensity adjustment actuator 122, i.e., a slider control, for allowing the user to adjust the intensity of the connected lighting load. The user interface 118 is operable to be received in the adapter opening 116.
With the faceplate adapter 110 attached, the traditional-style dimmer switch 110 may be installed next to a designer-style load control device in a standard multi-gang designer-style faceplate (e.g., such as the faceplate 40 of
A user interface 218 of the dimmer switch 200 comprises a slider control that is operable to be provided through the opening of a traditional-style faceplate, i.e., the adapter opening 216. The user interface 218 includes a knob 220 that has a pushbutton 222 and is coupled to a potentiometer (not shown) inside the dimmer switch 200 via a post 223. The post 223 has a width substantially the same as the width of the second opening 116. Movement of the knob 220 along the length of the adapter opening 116 adjusts the intensity of a connected lighting load (not shown). Actuation of the pushbutton 222 toggles the connected lighting load between on and off. A slider cover 240 is located behind the adapter 210. The slider cover 240 prevents debris and external objects from contacting the potentiometer inside the dimmer switch 200 as well as providing an attractive aesthetic. The post 223 extends through the slider cover 240, such that the slider cover 240 moves as the knob 222 moves.
The post 223 of the knob 222 extends through the adapter opening 216 and a slider opening 242 of the slider cover 240 to engage the potentiometer post 236. The slider opening 242 has a length and a width substantially equal to the length and the width of the post 223. The slider cover 240 has a plurality of arms 244 that allow the slider cover to rest on the support rails 248 and allow for movement of the slider cover such that the knob 222 is operable to move the length of the adapter opening 216.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
