Abstract
Abstract An easily assembled and dis-assembled knockdown EMI/RFI shielded electronic rack enclosure incorporating the structurally cooperative use of squaring bracket assemblies for the squared unitized corner joining of adjacent vertical side wall frame to horizontal top and bottom frame components and thereby substantially eliminate the distortion effects of racking forces, as well as the use of joining clamps for the unitized assembly connection of top and bottom enclosement panel components respectively to the opposing side enclosement panel components and thereby additionally substantially eliminate EMI/RFI shielding leaks resultant from mechanical shock forces.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
225 words
A knockdown EMI/RFI shielded electronic rack enclosure, said enclosure comprising in combination a three dimensional rectangular shaped mechanically rigid free-standing support structure comprised of a plurality of corner juncture interconnected vertical and horizontal frame members to describe a front and a rear and a pair of interconnected opposing side walls with a top and a bottom therefor, a corresponding plurality of unitary L-shaped squaring bracket assemblies each of said assemblies respectively having a horizontal flanged leg joined to a vertical flanged leg at a 90-degree angle by an interconnecting unflanged web segment for mechanically joining detachably by a nut and bolt connector means each of said plurality of corner juncture interconnected vertical and horizontal frame members describing said support structure, a door affixed by hinge means to enclosably cover the front of said support structure, a rear enclosement panel affixed by attachment means to enclosably cover the rear of said support structure, and a pair of side wall enclosement panels respectively affixed by an elongated U-shaped joining clamp adapted to slidably receive in close contact communication therewithin and compressively engage the upper and lower ends of said side wall enclosement panels respectively to a top enclosement panel end and a bottom enclosement panel end thereby to enclosably cover said pair of interconnecting opposing side walls and said top and said bottom of said support structure.
Claim 2
Dependent Claim
225 words
A knockdown EMI/RFI shielded electronic rack enclosure, said enclosure comprising in combination a three dimensional rectangular shaped mechanically rigid free-standing support structure comprised of a plurality of corner juncture interconnected vertical and horizontal frame members to describe a front and a rear and a pair of interconnected opposing side walls with a top and a bottom therefor, a corresponding plurality of unitary L-shaped squaring bracket assemblies each of said assemblies respectively having a horizontal flanged leg joined to a vertical flanged leg at a 90-degree angle by an interconnecting unflanged web segment for mechanically joining detachably by a nut and bolt connector means each of said plurality of corner juncture interconnected vertical and horizontal frame members describing said support structure, a door affixed by hinge means to enclosably cover the front of said support structure, a rear enclosement panel affixed by attachment means to enclosably cover the rear of said support structure, and a pair of side wall enclosement panels respectively affixed by an elongated U-shaped joining clamp adapted to slidably receive in close contact communication therewithin and compressively engage the upper and lower ends of said side wall enclosement panels respectively to a top enclosement panel end and a bottom enclosement panel end thereby to enclosably cover said pair of interconnecting opposing side walls and said top and said bottom of said support structure.
