US3783174A — Double isolated shielding enclosure

Claim 1

Independent Claim 183 words

In a double isolated electrically shielded screen room, the combination of: a plurality of panels each characterized by a frame having edges marginally recessed on the same side and facing the same direction a distance wider than it is deep defining a wide face and narrow shoulder disposed at an angle to each other; shielding covering opposite sides of all of said frames side by side and marginally terminating in pairs of coplanar flanges spaced and electrically isolated from each other on the wide faces of the recesses; a longitudinally disposed strip interengaging said shoulders of two frames and having a first surface area approximately twice said recess width and an outside shielding element centrally on said surface area bridging the two adjacent single flanges of said pairs of flanges; an inside shielding element on the remaining surface area of the strip marginally spaced and isolated from said outside shielding element thereon and bridging the remote single flanges of said coplanar pairs; and clamping means normal to said pairs of flanges compressibly clamping the shielding elements against the respective flanges bridged by them.

Claim 2

Dependent Claim 183 words

In a double isolated electrically shielded screen room, the combination of: a plurality of panels each characterized by a frame having edges marginally recessed on the same side and facing the same direction a distance wider than it is deep defining a wide face and narrow shoulder disposed at an angle to each other; shielding covering opposite sides of all of said frames side by side and marginally terminating in pairs of coplanar flanges spaced and electrically isolated from each other on the wide faces of the recesses; a longitudinally disposed strip interengaging said shoulders of two frames and having a first surface area approximately twice said recess width and an outside shielding element centrally on said surface area bridging the two adjacent single flanges of said pairs of flanges; an inside shielding element on the remaining surface area of the strip marginally spaced and isolated from said outside shielding element thereon and bridging the remote single flanges of said coplanar pairs; and clamping means normal to said pairs of flanges compressibly clamping the shielding elements against the respective flanges bridged by them.

Claim 3

Dependent Claim 52 words

The screen room called for in claim 1 in which said pairs of coplanar flanges are coplanar with each other and said widest faces of the recesses are coplanar with their frames coplanar and abutting to hold said inside shielding elements in contact with each other; and said remaining surface being flat.

Claim 4

Dependent Claim 45 words

The screen room called for in claim 1 in which said pairs of coplanar flanges lie in planes perpendicular to one another, and said first surface area comprises two portions disposed normal to each other along an outside corner encased by said outside shielding element.

Claim 5

Dependent Claim 131 words

A double isolated screen room comprising: a plurality of identical panels with peripheral flanges inwardly defining contiguous portions of a recess at each joint and having electrically conductive shielding members on opposite inner and outer sides that terminate marginally in spaced electrically isolated coplanar elements on the recess faces of the flanges; connector strips disposed in said recesses having electrically isolated shielding portions separately bridging coplanar elements of respective like shielding members at said joints; and elongated securing means interclamping the strips and flanges in a direction normal to their coplanar elements and disposed in contact with One of the isolated shielding portions at one end and spaced at its other end in electrically isolated relationship from the other of the shielding portion and the like shielding members bridged by it.

Claim 6

Dependent Claim 131 words

A double isolated screen room comprising: a plurality of identical panels with peripheral flanges inwardly defining contiguous portions of a recess at each joint and having electrically conductive shielding members on opposite inner and outer sides that terminate marginally in spaced electrically isolated coplanar elements on the recess faces of the flanges; connector strips disposed in said recesses having electrically isolated shielding portions separately bridging coplanar elements of respective like shielding members at said joints; and elongated securing means interclamping the strips and flanges in a direction normal to their coplanar elements and disposed in contact with One of the isolated shielding portions at one end and spaced at its other end in electrically isolated relationship from the other of the shielding portion and the like shielding members bridged by it.

Claim 7

Dependent Claim 95 words

The electrically isolated screen room defined in claim 4 in which said connector strips at said room corners are right angle strips where said panel flanges are disposed at right angles to each other and comprise a central section of an outside shielding portion extending longiitudinally along contiguous marginal edge portions of both faces defining the obtuse corner thereof, and the remaining area of the angle strips is covered with an inside shielding portion extending around the remaining corners of the angle strip and terminating marginally in isolated spaced relation from the outside shielding portion.

Claim 8

Dependent Claim 49 words

The electrically isolated screen room defined in claim 5 in which said central section terminates in end caps covering the ends of said strips to contact the outside shielding elements at a corner of a panel the plane of whose flange is parallel with that of the end cap.

Claim 9

Dependent Claim 81 words

The electrically isolated screen room defined in claim 5 in which one of said right angle strips at a triple plane room corner has an extension on one side end abutted in part by another right angle strip and both collectively end abut laterally against the end of a third strip disposed normal thereto and having an outside shielding end cap portion contacting the outside shielding elements at a corner of a panel engaged by said one and other angle strips.

Claim 10

Dependent Claim 123 words

The electrically isolated screen room defined in claim 5 in which one of said connector strips comprises a flat strip characterized by a narrow width of an outside shielding portion located centrally down the center of the recess face side of the strip and branching at the ends of the strip like a T to define a right angle portion carried on the outside end corner of the strip, said flat strip having an end of double thickness bodily defining a toe portion resting against an intermediate portion of the recess face of a panel flange disposed at right angle thereto at a dual plane room corner, and including two of said right angle strips end-abutting against opposite edges of said toe portion.

Claim 11

Dependent Claim 69 words

The electrically isolated screen room defined in claim 6 in which one of said connector strips comprises a flat strip characterized by a narrow width of an outside shielding portion located centrally down the center of the recess face side of the strip and branching at the ends of the strip like a T to define a right angle portion carried on the outside end corner of the strip.

Claim 12

Dependent Claim 49 words

The electrically isolated screen room defined in claim 9 in which said strip has an end of double thickness bodily defining a toe portion resting against an intermediate portion of the recess face of a panel flange disposed at a right angle thereto at a dual plane room corner.
