Abstract
Abstract A prefabricated shielded cabin which is shielded such that it is impermeable to high frequency radiation is assembled from individual prefabricated parts. The prefabricated parts or panels have a frame of solid tubes and half tubes welded around metal sheets. To assemble a cabin the half tubes are placed over the solid tubes. A mechanical connection between the half and solid tubes is provided with the aid of tubular clamps which slide over the half and solid tubes. Bolts are not required to assemble the shielded cabin of this invention.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A disassembleable, shielded cabin which is impermeable to high frequency radiation comprising: a. individual prefabricated wall, ceiling, and bottom panels, a majority of said panels having substantially uniform peripheral dimensions, each panel having a sheet metal portion and a load bearing frame attached thereto in a manner impermeable to high frequency radiation; b. some of said load bearing frames comprising circular solid tubes and other load bearing frames comprising cut away half tubes, said half tubes engaging the circular tubes of adjacent panels; c. contact spring elements located in contact with and between said half tubes and said circular tubes; d. tubular clamps disposed over said cut away half tubes and engaging said circular tubes to maintain the engagement to fix in place assembled panels; and e. said sheet metal portions being attached to said load-bearing frame at the outside of the shielded cabin.
Claim 2
Dependent Claim
144 words
A disassembleable, shielded cabin which is impermeable to high frequency radiation comprising: a. individual prefabricated wall, ceiling, and bottom panels, a majority of said panels having substantially uniform peripheral dimensions, each panel having a sheet metal portion and a load bearing frame attached thereto in a manner impermeable to high frequency radiation; b. some of said load bearing frames comprising circular solid tubes and other load bearing frames comprising cut away half tubes, said half tubes engaging the circular tubes of adjacent panels; c. contact spring elements located in contact with and between said half tubes and said circular tubes; d. tubular clamps disposed over said cut away half tubes and engaging said circular tubes to maintain the engagement to fix in place assembled panels; and e. said sheet metal portions being attached to said load-bearing frame at the outside of the shielded cabin.
Claim 3
Dependent Claim
18 words
The cabin according to claim 1, in which the frame and sheet metal portions consist of ferromagnetic material.
Claim 4
Dependent Claim
21 words
The cabin according to claim 2, in which the frame and sheet metal portions are provided with an electrically conductive surface.
Claim 5
Dependent Claim
13 words
The cabin of claim 2 in which the ferromagnetic material comprises chrome steel.
Claim 6
Dependent Claim
30 words
The cabin according to claim 1 in which said contact spring elements comprise a corrugated contact spring provided between the circular tube and the half tube engaging the circular tube.
Claim 7
Dependent Claim
101 words
The cabin according to claim 1 in which the ceiling, bottom, and some of the wall panels of the cabin are rectangular, the frames of these panels each consisting of two circular and two half tubes, the two circular tubes coming together at a corner, the two half tubes coming together at a corner, at least one rectangular wall panel having a frame which is the mirror image of a frame on at least one other rectangular wall panel, at least one bottom panel having a frame which is the mirror image of a frame on at least one ceiling panel.
Claim 8
Dependent Claim
13 words
The cabin of claim 1 in which all of the panels are square.
Claim 9
Dependent Claim
37 words
The cabin of claim 1 in which three types of panels are provided the frames of which respectively comprise all circular tubes, three circular tubes with one half tube, and three half tubes with one circular tube.
Claim 10
Dependent Claim
39 words
The cabin of claim 1 in which only one type of panel is provided and the frames consist in each case of two circular tubes coming together at a corner and two half tubes coming together at a corner.
Claim 11
Dependent Claim
21 words
The cabin of claim 1 in which at least six wall panels, two ceiling panels, and two bottom panels are provided.
Claim 12
Dependent Claim
134 words
A disassembleable, shielded cabin which is impermeable to high frequency radiation comprising: a. individual prefabricated wall, ceiling, and floor panels, a majority of said panels having substantially uniform peripheral dimensions, each panel having a sheet metal portion and a load bearing frame continuously attached without gaps around the sheet metal periphery; b. some of said load bearing frames comprising circular tubes and other load bearing frames comprising cut away half tubes, said cut away half tubes fitting around a portion of said circular tubes on adjacent panels; c. contact spring elements in gapless contact along substantially the entire longitudinal length between said cut away half tubes and said circular tubes; and d. tubular clamps disposed over said cut away half tubes around said circular tubes to fix in place assembled panels of the cabin.
Claim 13
