Abstract
Abstract A moisture-proof electrical outlet box includes a backwall with a generally continuous sidewall member upstanding therefrom to define a generally open face at the front edges thereof with a drip rail formed on the sidewall member and surrounding the box. The drip rail is preferably located in front of the front edges of the cable-access ports formed in the sidewall member. Advantageously, a frame-like flange member is formed at the front edges of the sidewall member and adapted to provide a moisture-proof seal with the coverplate. As preferably embodied, the drip rail and the flange member are formed integrally with the sidewall member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
158 words
A moisture resistant electrical outlet box which comprises: an integral wall structure including a backwall member and a generally continuous sidewall member extending from said backwall to define a chamber in said box and said sidewall providing an opening to said chamber at its front edges, said front edges including a mounting flange member therearound; cable-access port means formed in said wall structure adapted to provide access to the chamber in said box for one or more electrical cables; and deflecting means formed on said sidewall member, integrally therewith, said deflecting means substantially surrounding said box and being located generally rearward of said mounting flange, yet in front of all said port means, said deflecting means comprising a continuous drip rail projecting outwardly from the exterior surface of said sidewall member around the entire box to prevent any moisture collected on said sidewall member in front of said deflecting means from entering said box through said port means.
Claim 2
Dependent Claim
158 words
A moisture resistant electrical outlet box which comprises: an integral wall structure including a backwall member and a generally continuous sidewall member extending from said backwall to define a chamber in said box and said sidewall providing an opening to said chamber at its front edges, said front edges including a mounting flange member therearound; cable-access port means formed in said wall structure adapted to provide access to the chamber in said box for one or more electrical cables; and deflecting means formed on said sidewall member, integrally therewith, said deflecting means substantially surrounding said box and being located generally rearward of said mounting flange, yet in front of all said port means, said deflecting means comprising a continuous drip rail projecting outwardly from the exterior surface of said sidewall member around the entire box to prevent any moisture collected on said sidewall member in front of said deflecting means from entering said box through said port means.
Claim 3
Dependent Claim
61 words
A box according to claim 1, wherein said drip rail is located substantially adjacent the front edges of all said port means, such that said drip rail is located as far back as possible from the mounting flange member of said box to maximize the surface area of said sidewall over which moisture can collect without risk of entering the box.
Claim 4
Dependent Claim
29 words
A box according to claim 2, wherein said mounting flange member is adapted to form a substantially moisture-proof seal with a coverplate attached to the front of the box.
Claim 5
Dependent Claim
43 words
A box according to claim 3, wherein said mounting flange member extends generally parallel to said backwall member and is adapted to help locate said box in a suitable opening formed in a structural wall in which said box is to be installed.
Claim 6
Dependent Claim
17 words
A box according to claim 4, wherein said drip rail projects essentially perpendicular from said sidewall member.
Claim 7
Dependent Claim
21 words
A box according to claim 5, wherein said mounting flange member and said drip rail are formed integrally with said box.
Claim 8
Dependent Claim
97 words
A box according to claim 6, which further includes threaded fastener mounting means formed at said front edges, said mounting means adapted to permit mounting of an electrical wiring device to said box and comprising: a pair of lug members formed on said sidewall portion, generally opposite each other; and a hole formed in each lug member, each said hole being open at its front end but sealed at its back end and adapted to retain a threaded fastener, such that the electrical fixture can be mounted in the box by threaded fasteners threaded into said boreholes.
Claim 9
Dependent Claim
17 words
A box according to claim 7, wherein said box is integrally formed from a moldable plastic material.
Claim 10
Dependent Claim
47 words
A box according to claim 8, wherein said box is generally rectangular and said sidewall member includes a pair of generally oppositely disposed endwall portions and a pair of generally oppositely disposed sidewall portions, and wherein said cable entry port means are formed on said endwall portions.
Claim 11
Dependent Claim
12 words
A box according to claim 8, wherein said box is generally round.
Claim 12
Dependent Claim
39 words
A box according to claim 2, wherein all said port means are formed in said sidewall member and terminate generally at said backwall, the front edges of all said port means defining a plane essentially parallel to said backwall.
Claim 13
Dependent Claim
19 words
A box according to claims 2, 3 or 7, wherein said sidewall tapers slightly inwardly in the front-to-back direction.
Claim 14
Dependent Claim
153 words
An improved outlet box according to claim 11, which further includes at least two essentially parallel bead-like projections formed on the front surface of said flange, said bead-like projections extending continuously around the front surface of said flange and conforming generally to the shape of a coverplate, each said projection being proportioned to coincide at least in part with corresponding portions of the lip on the back of various sized coverplates to be attached to the front edges of the box, such that when a coverplate is secured to the box with a compressible gasket made of resilient material positioned between the front surface of the flange and the back of the coverplate, the gasket can be compressed between various portions of said bead-like projections and the coverplate lip along essentially the entire length of the coverplate lip even though the coverplate lip does not coincide exactly with either of said projections separately.
Claim 15
Dependent Claim
117 words
An improved moisture resistant electrical outlet box having a backwall with a generally continuous sidewall member extending therefrom to define a chamber interior of said box and open along the front edges of the sidewall member, wherein the improvement comprises: a flange formed at the front edges of the sidewall member, said flange extending continuously around the front opening of the box, and a drip rail projecting outwardly from said sidewall member, from its exterior surface, around the entire box, said drip rail being located rearward of said flange to prevent any moisture collecting on said sidewall between said flange and said drip rail from entering the box through port means located rearward of said drip rail.
Claim 16
Dependent Claim
117 words
An improved moisture resistant electrical outlet box having a backwall with a generally continuous sidewall member extending therefrom to define a chamber interior of said box and open along the front edges of the sidewall member, wherein the improvement comprises: a flange formed at the front edges of the sidewall member, said flange extending continuously around the front opening of the box, and a drip rail projecting outwardly from said sidewall member, from its exterior surface, around the entire box, said drip rail being located rearward of said flange to prevent any moisture collecting on said sidewall between said flange and said drip rail from entering the box through port means located rearward of said drip rail.
Claim 17
Dependent Claim
54 words
An improved box according to claim 13, wherein said flange includes at least one aperture formed therein and located outside the perimeter defined by said projections, such that said box can be secured to a structural wall by a nail, threaded fastener or the like inserted through each said aperture and into the wall.
Claim 18
Dependent Claim
25 words
An improved box according to claim 13 or 15, wherein said flange, said bead-like projections and said drip rail are formed integrally with said box.
