Abstract
A one-piece cable support including an integral box-shaped mounting assembly. The box-shaped mounting assembly extends over a cable tray portion of the cable support and includes several optional mounting apertures. Once secured to a building structure through the box-shaped mounting assembly, the weight of a suspended bundle of cables is distributed evenly below the assembly, thereby permitting the load to be balanced evenly below the assembly and reducing the bending moment and therefore the stress on the wall portion connecting the cable tray and mounting assembly portions of the support. An integral bracket assembly is provided on the bottom of the cable support to allow easy ganging of multiple cable supports without the need for specialized brackets.
Claims12
A cable support comprising:
- a cable tray including edges and a substantially flat bottom;
- a front wall integral with and extending from a first side of said tray, said front wall having edges and an end;
- a rear wall integral with and extending from a second side of said tray parallel to said front wall, said rear wall extending substantially beyond said end of said front wall, said rear wall narrowing beyond said end of said front wall, said rear wall including edges;
- a reinforcing flange on said edges of said cable tray, said front wall, and said rear wall, said reinforcing flange extending outwards of said cable tray and said walls, said flange having an outer end;
- a box-shaped mounting assembly integral with said rear wall and extending substantially above said cable tray, said assembly including a top wall and side walls, said side walls including a front and a rear side wall, said front side wall terminating in an end facing said cable tray;
- an aperture in each of said side walls;
- a raised area surrounding said aperture in said rear side walls, said raised area extending substantially as far as said outer end of said reinforcing flange;
- receiving tabs lanced out of said bottom, said tabs extending outwardly from said cable tray, said tabs parallel to each other and forming a gap there between, said gap slightly larger than the distance across the outer surface of said side walls of said mounting assembly;
- and
- an aperture in each of said tabs, said apertures in said tabs aligning with two of said apertures in said side walls of said mounting assembly to allow easy connection of two or more of said cable supports by a suitable fastener fastened between said apertures in said tabs of a first cable support and said apertures in said side walls of said mounting assembly of a second cable support.
7 more elements
A method of suspending multiple levels of cable bundles comprising the steps of:
- providing a plurality of-cable supports with each of said cable supports having a cable tray including a bottom, an integral box-shaped mounting assembly having side walls extending substantially above said cable tray, and receiving tabs extending outwardly and downwardly from said bottom of said cable tray and forming a gap there between;
- providing an aperture in each of said side walls and an aperture in each of said tabs with said apertures positioned such that insertion of said side walls of said assembly into said gap enables alignment of said apertures in said side walls and said apertures in said tabs;
- securing a first of said cable supports to a supporting structure by a fastener inserted through said apertures in said mounting assembly and into said structure;
- rotating a second of said cable supports with respect to said first cable support such that the desired alignment is reached between said second and said first cable support;
- inserting said side walls of said second cable support within said gap between said tabs of said first cable support;
- and
- inserting and securing a fastener within said apertures in said side walls of said bottom cable support and said apertures in said tabs of said top cable support.

A cable support comprising:
- a cable tray including edges and a substantially flat bottom;
- a front wall integral with and extending from a first side of said tray, said front wall having edges and an end;
- a rear wall integral with and extending from a second side of said tray parallel to said front wall said rear wall extending substantially beyond said end of said front wall, said rear wall narrowing beyond said end of said front wall, said rear wall including edges;
- a reinforcing flange on said edges of said cable tray, said front wall, and said rear wall, said reinforcing flange extending outwards of said cable tray and said walls, said flange having an outer end;
- a box-shaped mounting assembly integral with said rear wall and extending substantially above said cable tray, said assembly including a top wall and side walls, said side walls including a front and a rear side wall, said front side wall terminating in an end facing said cable tray;
- an aperture in each of said side walls;
- receiving tabs lanced out of said bottom, said tabs extending outwardly from said cable tray said tabs parallel to each other and forming a gap there between, said gap slightly larger than the distance across the outer surface of said side walls of said mounting assembly;
- and
- an aperture in each of said tabs, said apertures in said tabs aligning with two of said apertures in said side walls of said mounting assembly to allow easy connection of two or more of said cable supports by a suitable fastener fastened between said apertures in said tabs of a first cable support and said apertures in said side walls of said mounting assembly of a second cable support.
