1. An electrical shielding chamber comprising:
- first, second, third, fourth, fifth and sixth electrically conductive rigid walls in electrical contact with each other, wherein said first wall contains a first door and said second wall contains a second door and said first and second doors are each selectively attachable to at least three of said third, fourth, fifth and sixth walls;
wherein stitching through each of said walls is covered by a layer of metallized fabric on at least one side of the wall for preventing leakage of electromagnetic radiation; and
wherein the chamber is collapsible for forming a substantially flat package and expandable for forming a substantially electrically shielded compartment.

Abstract
An electrical shielding chamber has six electrically conductive rigid walls in electrical contact with each other. A first wall forms a first door and a second wall forms a second door, each of which is selectively attachable to at least three other walls. The chamber is collapsible for forming a substantially flat package, and expandable for forming a substantially electrically-shielded compartment.

14. A portable electromagnetic shielding cage comprising:
-
a top wall, a bottom wall, a right side wall, a left side wall, a front wall and a back wall, each of the walls comprising a rigid nonconductive sheet material, a layer of metal, an inner layer of metallized fabric, and an outer layer of metallized fabric; means for forming a flexible electrically conductive hinge between each said wall and at least one adjacent wall for (a) forming a door for placing instruments inside the shielding cage, and (b) folding all of the walls between a first position for forming a rectangular parallelepiped and a second position with the walls in face-to-face engagement for forming a flat package; and a flexible edge flap of conductive fabric along each hingeless edge of each of said walls, for overlapping an edge of the at least one adjacent wall for preventing leakage of electromagnetic radiation. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
