Abstract
Abstract An electrical junction box mounting arrangement which includes a cup-shaped member having a flange at its open end engaging the periphery of an opening through the inner wall of a junction box, with the remainder of the cup-shaped member extending through the opening, a spacer sleeve circumscribing the projecting portion of the cup-shaped member and engaging the wall of the junction box and the surface to which the same is to be secured, a stud extending from the surface through the spacer sleeve and an opening in the cup-shaped member where it is engaged by a nut which clamps the elements in place, the spacer sleeve optionally including teeth in its end surfaces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
191 words
In combination with a support structure, an electrical box assembly comprising a box adapted to receive electrical components, said box having an inner wall and additional walls extending from said inner wall, said inner wall having an opening therethrough, a first threaded element, a second threaded element, said first threaded element being attached to said support structure, a spacer adjacent said first threaded element, one end of said spacer engaging said structure and the opposite end of said spacer engaging the outside surface of said inner wall of said box, and a member having a first portion engaging the inside surface of said inner wall, and a second portion extending from said first portion through said opening in said inner wall, said second portion having an opening therethrough receiving one of said threaded elements, said second threaded element being meshed with said first threaded element and engaging said second portion of said member for exerting a force on said member to clamp said inner wall between said spacer and said first portion of said member, and to force said spacer against said structure for thereby securing said box to said structure.
Claim 2
Dependent Claim
191 words
In combination with a support structure, an electrical box assembly comprising a box adapted to receive electrical components, said box having an inner wall and additional walls extending from said inner wall, said inner wall having an opening therethrough, a first threaded element, a second threaded element, said first threaded element being attached to said support structure, a spacer adjacent said first threaded element, one end of said spacer engaging said structure and the opposite end of said spacer engaging the outside surface of said inner wall of said box, and a member having a first portion engaging the inside surface of said inner wall, and a second portion extending from said first portion through said opening in said inner wall, said second portion having an opening therethrough receiving one of said threaded elements, said second threaded element being meshed with said first threaded element and engaging said second portion of said member for exerting a force on said member to clamp said inner wall between said spacer and said first portion of said member, and to force said spacer against said structure for thereby securing said box to said structure.
Claim 3
Dependent Claim
28 words
A device as recited in claim 1 in which said second portion of said member provides a recess, said second threaded element being entirely received within said recess.
Claim 4
Dependent Claim
33 words
A device as recited in claim 1 in which said spacer is a sleeve engaging said inner wall around said opening in said inner wall, said second portion being received in said sleeve.
Claim 5
Dependent Claim
27 words
A device as recited in claim 3 in which said sleeve includes opening means in the wall thereof for permitting drainage from the inside of said sleeve.
Claim 6
Dependent Claim
