Abstract
Abstract A cable trough comprising hollow side rails and hollow crossbars, both rectangular in configuration, with the crossbars being edgewise arranged in the longitudinal direction of the side rails. One side surface of each of the crossbars is substantially flush with one edge of each of side rails so that a trough is formed on top of the crossbars and between the side rails. The crossbars may be telescoping for width adjustment. The side rails may be endwise joined with similar side rails by means of a connecting bar positioned within the hollow structure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
291 words
A cable trough comprising: a fist side rail; a second side rail; both said first and second side rails being made of tubular material of uniform cross section, said tubular material having a sectional configuration defined by a rectangle, having first and second equal sides and first and second equal edges, said sides being of greater dimension than said edges; said first and second side rails being positioned so that said first sides of said first and second side rails face each other and lie in substantially parallel planes, and being positioned so that said first edge on said first side rail and said first edge on said second side rail lie in a first common plane while said second edge on said first side rail and said second edge on said second side rail lie in a second plane parallel to said first plane; a plurality of crossbars, each of said crossbars being secured at one end to said first side of said first rail and at the other end to said first side of said second rail, each of said crossbars being tubular, and having an exterior rectangular configuration, at least part of each of said crossbars being of the same cross-sectional dimensions as said first and second side rails so that said crossbars have sides and edges with said sides of said crossbars being of larger dimension than said edges of said crossbars, said cross bars being connected to both said first and second side rails so that one side of each of said crossbars lies in said first plane defined by said first edges of said first and second rails so that at least a part of each of said crossbars lies coplanar in said first plane.
Claim 2
Dependent Claim

A cable trough comprising: a fist side rail; a second side rail; both said first and second side rails being made of tubular material of uniform cross section, said tubular material having a sectional configuration defined by a rectangle, having first and second equal sides and first and second equal edges, said sides being of greater dimension than said edges; said first and second side rails being positioned so that said first sides of said first and second side rails face each other and lie in substantially parallel planes, and being positioned so that said first edge on said first side rail and said first edge on said second side rail lie in a first common plane while said second edge on said first side rail and said second edge on said second side rail lie in a second plane parallel to said first plane; a plurality of crossbars, each of said crossbars being secured at one end to said first side of said first rail and at the other end to said first side of said second rail, each of said crossbars being tubular, and having an exterior rectangular configuration, at least part of each of said crossbars being of the same cross-sectional dimensions as said first and second side rails so that said crossbars have sides and edges with said sides of said crossbars being of larger dimension than said edges of said crossbars, said cross bars being connected to both said first and second side rails so that one side of each of said crossbars lies in said first plane defined by said first edges of said first and second rails so that at least a part of each of said crossbars lies coplanar in said first plane.
Claim 3
Dependent Claim
43 words
The cable trough of claim 1 wherein each of said crossbars is a unitary structure and is of the same cross-sectional dimensions as said side rails throughout the entire length of said crossbars, said crossbars being secured to said side rails by welding.
Claim 4
Dependent Claim
54 words
The cable trough of claim 2 wherein first and second cable trough sections are arranged in endwise abutting aligned relationship of said cable trough side rails, a connector member inserted within the hollow interior of the ends of each of said endwise abutting side rails to maintain said endwise abutting side rails in alignment.
Claim 5
Dependent Claim
38 words
The cable trough of claim 3 wherein said connector member has a pin extending laterally therefrom, said pin engaging said endwise abutting side rails to maintain said connector member engaged in both of said endwise abutting side rails.
Claim 6
Dependent Claim
40 words
The cable trough of claim 1 wherein said crossbars each comprise first and second telescoping crossbar sections, said first crossbar sections being connected to said first side rail and said second crossbar sections being connected to said second side rail.
Claim 7
Dependent Claim
21 words
The cable trough of claim 5 wherein both said first and second crossbar sections are hollow and rectangular in cross section.
Claim 8
Dependent Claim
45 words
The cable trough of claim 6 wherein said second crossbar sections are formed of the same stock as said second side rail, and said first crossbar sections are formed of stock of such dimension as to telescope into the interior of said second crossbar sections.
Claim 9
Dependent Claim
54 words
The cable trough of claim 7 wherein first and second cable trough sections are arranged in endwise abutting aligned Relationship of said cable trough side rails, a connector member inserted within the hollow interior of the ends of each of said endwise abutting side rails to maintain said endwise abutting side rails in alignment.
Claim 10
Dependent Claim
38 words
The cable trough of claim 8 wherein said connector member has a pin extending laterally therefrom, said pin engaging said endwise abutting side rails to maintain said connector member engaged in both of said endwise abutting side rails.
