Abstract
Abstract An enclosure for electrical components comprises an electrically non-conductive molded plastic liquid tight rectangular box-like container having an upwardly open end and defined by side walls joined at upwardly extending corners. Each of the upwardly extending corners includes a vertically extending channel with a vertical access slot. The access slot is narrower than the associated channel to provide a fastener receiving opening for mounting electrical structure within the enclosure. Fasteners are mounted for vertical adjustment in the channels to allow selective positioning of panels or components in the enclosure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
An enclosure for electrical components and the like, comprising: an electrically non-conductive molded plastic unitary structure having a rectangular bottom wall and four upwardly extending side walls integral therewith and joined to form a liquid tight rectangular box-like container having an upwardly open end and four upwardly extending corners at the junctures of said side walls; each of said upwardly extending corners including a separate pair of rib members associated therewith and molded integrally with said walls and extending from said bottom wall to said open end, the respective ribs of each said pair of ribs being located on opposite sides of the associated corner with each rib having a tapered cross-section in planes parallel to the bottom wall and having a terminal end which is generally parallel to the associated corner and extends toward and terminates parallel to the terminal end of the associated rib to define a vertically extending channel with a vertical access slot, said access slot being narrower than the associated channel to provide a fastener receiving means for mounting electrical structure within said enclosure.
Claim 2
Dependent Claim
179 words
An enclosure for electrical components and the like, comprising: an electrically non-conductive molded plastic unitary structure having a rectangular bottom wall and four upwardly extending side walls integral therewith and joined to form a liquid tight rectangular box-like container having an upwardly open end and four upwardly extending corners at the junctures of said side walls; each of said upwardly extending corners including a separate pair of rib members associated therewith and molded integrally with said walls and extending from said bottom wall to said open end, the respective ribs of each said pair of ribs being located on opposite sides of the associated corner with each rib having a tapered cross-section in planes parallel to the bottom wall and having a terminal end which is generally parallel to the associated corner and extends toward and terminates parallel to the terminal end of the associated rib to define a vertically extending channel with a vertical access slot, said access slot being narrower than the associated channel to provide a fastener receiving means for mounting electrical structure within said enclosure.
Claim 3
Dependent Claim
37 words
The enclosure as defined in claim 1 wherein the ribs in each pair have planar surfaces facing the interior of the enclosure which extend from the bottom to the open end and lie in the same plane.
Claim 4
Dependent Claim
21 words
An enclosure as defined in claim 1 wherein each pair of ribs is generally parallel to every other pair of ribs.
Claim 5
Dependent Claim
24 words
An enclosure as defined in claim 3 wherein said ribs each have a relatively thick base and taper to a relatively thin terminal end.
Claim 6
Dependent Claim
16 words
An enclosure as defined in claim 3 wherein said ribs are integral with the side walls.
Claim 7
Dependent Claim
39 words
An enclosure as defined in claim 1 including a support wall spaced from said bottom wall, said support wall being supported by adjustable connecting means extending from said support wall into at least one of the vertically extending channels.
Claim 8
Dependent Claim
27 words
An enclosure as defined in claim 6 wherein said adjustable connecting means are releasably clamped to the ribs which define the at least one vertically extending channel.
Claim 9
Dependent Claim
183 words
An enclosure for electrical components and the like, comprising: an electrically non-conductive molded plastic unitary structure having a rectangular bottom wall and four upwardly extending side walls integral therewith and joined to form a liquid tight rectangular box-like container having an upwardly open end and four upwardly extending corners at the junctures of said side walls; each of said upwardly extending corners including a separate pair of rib members associated therewith and extending from said bottom wall to said open end, each pair of ribs being generally parallel to every other pair of ribs and the respective ribs of each said pair of ribs being located on opposite sides of the associated corner with each rib having a relatively thick base tapering to a relatively thin terminal end which is generally parallel to the associated corner and extends toward and terminates parallel to the terminal end of the associated rib to define a vertically extending channel with a vertical access clot, said access slot being narrower than the associated channel to provide a fastener receiving means for mounting electrical structure within said enclosure.
