Abstract

Apparatus, system, and method for ganging a plurality of wall mounted control devices, such as keypads. Particularly, an assembly of ganged control devices is provided comprising a pair of adjacently positioned control devices each adapted to control at least one function of at least one associated load. Each control device comprises a housing assembly and at least one button attached to the housing assembly. The housing assembly comprises a pair of oppositely disposed side surfaces each comprising a pair of vertically aligned recesses. Each recess comprises a tapered inner side wall. The assembly further comprises an alignment plate comprising a vertical wall adapted to be positioned in between the pair of control devices and a pair of vertically aligned tabs traversely extending from oppositely disposed side surfaces of the vertical wall. Each tab comprises a tapered outer side wall. The tabs are sized, shaped, and positioned to be inserted into the recesses such that the tapered outer side walls of the tabs form a friction fit with the tapered inner side walls of the recesses to removably attach and align the pair of control devices.

First claim

What is claimed is:

1. An assembly of ganged control devices comprising:
a pair of adjacently positioned control devices each adapted to control at least one function of at least one associated load, wherein each control device comprises a housing assembly and at least one button attached to the housing assembly, wherein the housing assembly comprises a pair of oppositely disposed side surfaces each comprising a plurality of recesses; and
an alignment plate comprising a vertical wall adapted to be positioned in between the pair of control devices and a plurality of tabs traversely extending from oppositely disposed side surfaces of the vertical wall, wherein the tabs are sized, shaped, and positioned for mating with the recesses in the side surfaces of the pair of control devices to removably attach and align the pair of control devices;
wherein each side surface of the vertical wall of the alignment plate further comprise at least one bump extending therefrom in proximity to a rear edge of the vertical wall to compensate for a space created between the housing assemblies of the pair of adjacent control devices.

2. The assembly of claim 1 , wherein the plurality of recesses on each side surface of each control device comprise a pair of vertically aligned recesses, and wherein the plurality of tabs on each side surface of the alignment plate comprise a pair of vertically aligned tabs.

3. The assembly of claim 2 , wherein the pair of vertically aligned recesses are disposed proximate to a front side of each control device, wherein each control device further comprises a third recess disposed proximate to a rear side of each control device, and wherein each side surface of the alignment plate further comprises a third tab positioned for mating with the third recess on a corresponding side surface of a corresponding control device.

4. The assembly of claim 1 , wherein each recess comprises a tapered inner side wall and wherein each tab comprises a tapered outer side wall adapted to form a friction fit with the tapered inner side wall of a corresponding recess.

5. The assembly of claim 1 , wherein the alignment plate is adapted to removably attach the pair of adjacently positioned control devices by having the plurality of tabs press fit into corresponding recesses in the control devices.

6. The assembly of claim 1 , wherein the vertical wall of the alignment plate is sized and shaped to substantially correspond to a size and shape of one of the side surfaces of the control devices.

7. The assembly of claim 1 , wherein at least one button of one of the pair of control devices is adapted to be disposed adjacent to at least one button of another one of the pair of control devices forming substantially no space therebetween, wherein the alignment plate is adapted to align the adjacently disposed buttons.

8. The assembly of claim 7 further comprising a faceplate comprising a single opening sized and shaped to receive the buttons of the pair of adjacently disposed control devices.

9. The assembly of claim 8 , wherein a front surface of each button is adapted to be substantially flush with a front surface of the faceplate.

10. The assembly of claim 1 , wherein the plurality of tabs comprise a substantially equal size that mate with the plurality of recesses that comprise a substantially equal size.

11. The assembly of claim 1 , wherein at least one tab comprises a different size from the plurality of tabs that mates with at least one recess that comprises a different size from the plurality of recesses.

12. The assembly of claim 1 , wherein the vertical wall of the alignment plate comprises a projecting portion projecting from a rear edge of the vertical wall adapted to provide a gripping surface.

13. The assembly of claim 1 further comprising at least one additional control device adapted to be removably attached to and aligned with the pair of control devices via at least one additional alignment plate.

14. An assembly of ganged control devices comprising:
a pair of adjacently positioned control devices each adapted to control at least one function of at least one associated load, wherein each control device comprises a housing assembly and at least one button attached to the housing assembly, wherein the housing assembly comprises a pair of oppositely disposed side surfaces each comprising a pair of vertically aligned recesses, wherein each recess comprises an inner side wall that tapers inwardly from the side surface of the respective control device; and
an alignment plate comprising a vertical wall adapted to be positioned in between the pair of control devices and a pair of vertically aligned tabs traversely extending from oppositely disposed side surfaces of the vertical wall, wherein each tab comprises an outer side wall that tapers inwardly from the respective side surface of the vertical wall of the alignment plate, wherein the tabs are sized, shaped, and positioned to be inserted into corresponding recesses such that the tapered outer side walls of the tabs form a friction fit with the tapered inner side walls of the recesses to removably attach and align the pair of control devices.

15. The assembly of claim 14 , wherein the pair of recesses comprise a pair of different sizes and wherein the pair of tabs comprise a pair of different sizes that complement the different sizes of the pair of recesses.

16. A method for ganging at least a pair of control devices each adapted to control at least one function of at least one associated load, the method comprising the steps of:
inserting a plurality of tabs that traversely extend from a first side surface of a vertical wall of an alignment plate into a plurality of recesses formed on a side surface of a housing assembly of a first control device;
inserting a plurality of tabs that traversely extend from a second side surface of the vertical wall of the alignment plate into a plurality of recesses formed on a side surface of a housing assembly of a second control device;
wherein each recess comprises an inner side wall that tapers inwardly from the side surface of the respective control device, wherein each tab comprises an outer side wall that tapers inwardly from the respective side surface of the vertical wall of the alignment plate; and
applying pressure to the pair of control devices toward each other such that the tapered outer side walls of the tabs on the alignment plate form a friction fit with the tapered inner side walls of the respective recesses of the pair of control devices to removably secure the pair of control devices to the alignment plate.

17. The method of claim 16 , wherein each control device comprises at least one button attached to the housing assembly, wherein the at least one button of one of the pair of control devices is adapted to be disposed adjacent to the at least one button of another one of the pair of control devices forming substantially no space therebetween, wherein the alignment plate is adapted to align the adjacently disposed buttons.

18. The method of claim 16 further comprising the steps of:
securing the ganged control devices to an electrical box; and
securing a faceplate to the ganged control devices, wherein the faceplate comprises a single opening sized and shaped to receive the buttons of the pair of ganged control devices.
