Framework for supporting air cooled electrical and electronic equipment

Claim 2

A framework comprising at least two vertical frames horizontally spaced apart and each having spaced vertical columns and top and bottom members connected to said columns, a plurality of horizontal shelf-like means mounted on said frames, each of said shelf-like means having cross members with each, respectively, extending horizontally between said columns of one said frame and each of said shelf-means having horizontal support beams extending in spaced relation to one another and between said cross members, said support beams each having a generally flat U-shape formed by each having spaced, facing side walls and a connecting wall extending between said side walls, dimmer units for controlling load current passing therethrough and said dimmer units mounted on said connecting walls for cooling by air currents flowing through said framework.

Claim 3

The framework as set forth in claim 1 wherein said frames are connected by tie bars.

Claim 4

A framework as set forth in claim 1 wherein said connecting wall faces upwardly and said dimmer units are mounted on said walls.

Claim 5

A framework as set forth in claim 1 wherein said support beams have L-shaped members mounted on one side of said beams and forming a groove with the mounted side of said support beam.

Claim 6

A framework as set forth in claim 1 wherein said support beams are connected by vertical bus means.

Claim 7

A framework as set forth in claim 5 wherein one bus means is attached to a vertically spaced support beams position one above the other and a second bus is attached to said other support beams vertical position above one another.

Claim 8

A framework as set forth in claim 3 wherein means are provided for supporting power cables between the side walls of respective connecting support beams.

Claim 9

A framework as set forth in claim 1 wherein said support beams are electrically insulated from said cross members.

Claim 10

A framework as set forth in claim 1 wherein casing means are provided mounted on an end frame member for supporting a cross connected panel.

Claim 11

A framework as set forth in claim 1 wherein sheet metal covering is provided between said frames.

Claim 12

A framework comprising at least two vertical frames each having spaced vertical columns with passages therein and top and bottom members welded to said columns, a plurality of shelf means mounted on said frames, each of said shelf means having two cross members with passages therein, each cross member extending horizontally between said columns of said respective frames with the passages of said cross members connected to the passages of said columns and said shelf means having horizontal support beams extending in spaced relation to one another and between said cross members, means securing said support beams to and electrically isolating said beams from said cross members, means connected to said beams for supplying load current thereto, dimmer units mounted vertically on said beams and electrically connected thereto for passing load current therethrough and cables in said passages connected to said dimmer units for controlling the load current.

Claim 13

A framework comprising at least two vertical frames each having spaced vertical columns with passages therein and top and bottom members welded to said columns, a plurality of shelf means mounted on said frames, each of said shelf means having two cross members with passages therein, each cross member extending horizontally between said columns of said respective frames with the passages of said cross members connected to the passages of said columns and said shelf means having horizontal support beams extending in spaced relation to one another and between said cross members, means securing said support beams to and electrically isolating said beams from said cross members, means connected to said beams for supplying load current thereto, dimmer units mounted vertically on said beams and electrically connected thereto for passing load current therethrough and cables in said passages connected to said dimmer units for controlling the load current.
