Abstract
Abstract An electromagnetically compatible vertical enclosure for the operating system of transmission equipment, in particular for transmission by radio beam, the enclosure containing a set of electrical modules and having a top flap and a bottom flap for closing said structure. The flaps are removable and are hinged at the top and at the bottom of the structure about horizontal axles fixed to the structure, thereby making it possible to provide completely unhindered access to the modules. The invention is particularly suitable for radio beam transmission.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
An electromagnetically compatible vertical enclosure containing a set of electrical modules of an operating system of radio beam transmission equipment, said enclosure comprising: a top flap and a bottom flap closing off the front of said enclosure, said flaps including removable hinges at the top and at the bottom of said top and bottom flaps respectively and engaged about respective horizontal axles fixed to said enclosure, thereby making it possible to provide completely unhindered access to the modules, the bottom of the top flap overlapping the top of the bottom flap and said enclosure further comprising a handle fixed to one of said top flap and said bottom flap and locking on a catch fixed to the enclosure.
Claim 2
Dependent Claim
118 words
An electromagnetically compatible vertical enclosure containing a set of electrical modules of an operating system of radio beam transmission equipment, said enclosure comprising: a top flap and a bottom flap closing off the front of said enclosure, said flaps including removable hinges at the top and at the bottom of said top and bottom flaps respectively and engaged about respective horizontal axles fixed to said enclosure, thereby making it possible to provide completely unhindered access to the modules, the bottom of the top flap overlapping the top of the bottom flap and said enclosure further comprising a handle fixed to one of said top flap and said bottom flap and locking on a catch fixed to the enclosure.
Claim 3
Dependent Claim
13 words
A vertical enclosure according to claim 1, wherein the flaps are metal flaps.
Claim 4
Dependent Claim
24 words
A vertical enclosure according to claim 1, wherein each flap is provided with a 90° flange along each side projecting inwardly of the enclosure.
Claim 5
Dependent Claim
50 words
A vertical enclosure according to claim 3, wherein the modules have flanks and the enclosure includes vertical bars provided with vertical grooves in two opposite faces, the grooves in one face receiving the flanges on the flaps, and the grooves in the opposite face receiving said flanks of the modules.
Claim 6
Dependent Claim
30 words
A vertical enclosure according to claim 4, wherein each flap is provided with an electrically conductive gasket interposed between the flap and one of said vertical bars of the enclosure.
Claim 7
Dependent Claim
