COLLAPSIBLE SCREENED CHAMBER WITH DOUBLE SCREEN Russian patent published in 2016 - IPC G12B17/02 H05K9/00 

FIELD: construction.

SUBSTANCE: chamber comprises rectangular modules, each having a frame from a dielectric material. Each frame is coated at two sides by webs from an electroconductive material, adjacent side edges of neighbouring modules are electrically and mechanically connected to each other, forming solid inner and outer screens, galvanically disconnected from each other. The frame is made of a timber of a square cross section of two types, in the timber of the first type along the middle of one of the sides there is a symmetrical stepped slot, and in the timber of the second type along the middle of one of sides there is a ridge, at the sides of which there are adjoining slots. The specified web on each side of the module is extended to the edges of the module, bent and inserted into the slots of timber of both types, in the slots the web is pressed by a metal strip.

EFFECT: development of the chamber design using standard joiner's elements, making it possible to manually assemble or disassemble, without the limitation of the minimum area and height of a room for the chamber, and also without the loss of screening efficiency.
