Abstract

Abstract A mounting frame facilitates the installation of ganged electrical devices into a single switchbox. The frame is a rectangular plate with a rectangular opening and provides a rigid support for the devices. Support is needed when the wall on which devices are to be mounted is not planar or when the switchbox is not properly mounted into the wall. The frame can also include markings that help to align the devices to permit a multigang faceplate to snap onto the devices. An alignment frame provides markings to help align the devices, without also providing a rigid support.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 99 words
A multigang electrical assembly comprising, in combination, a plurality of adjacent electrical devices mountable into a switchbox, a single snap-on faceplate engaging each of said devices, and a frame providing a rigid planar mounting surface for said devices between said devices and said switchbox, said frame comprising a substantially rectangular first plate, having: a front surface, having a plurality of alignment markers for independently positioning each of said devices in juxtaposition to receive said faceplate, (b) a back surface, (c) a substantially rectangular opening, and (d) a plurality of holes positioned to permit alignment with holes in said switchbox.
Claim 2
Dependent Claim 99 words
A multigang electrical assembly comprising, in combination, a plurality of adjacent electrical devices mountable into a switchbox, a single snap-on faceplate engaging each of said devices, and a frame providing a rigid planar mounting surface for said devices between said devices and said switchbox, said frame comprising a substantially rectangular first plate, having: a front surface, having a plurality of alignment markers for independently positioning each of said devices in juxtaposition to receive said faceplate, (b) a back surface, (c) a substantially rectangular opening, and (d) a plurality of holes positioned to permit alignment with holes in said switchbox.
Claim 3
Dependent Claim 18 words
The assembly of claim 1 in which said first plate comprises steel at least about 2 mm thick.
Claim 4
Dependent Claim 16 words
The assembly of claim 1 in which said first plate is formed from two interlocking parts.
Claim 5
Dependent Claim 14 words
The assembly of claim 1 in which said markers protrude from said front surface.
Claim 6
Dependent Claim 23 words
The assembly of claim 1 further comprising a flange extending substantially normal to said first plate at the periphery of said rectangular opening.
Claim 7
Dependent Claim 18 words
The assembly of claim 5 in which said first plate comprises steel at least about 0.5 mm thick.
Claim 8
Dependent Claim 16 words
The assembly of claim 5 in which said first plate comprises steel about 0.7 mm thick.
Claim 9
Dependent Claim 52 words
The assembly of claim 5, further comprising a strengthening bracket, comprising a substantially rectangular second plate, for placement against said back surface of said first plate, said second plate having (a) a substantially rectangular opening and (b) a plurality of holes positioned to permit alignment with said holes in said first plate.
