DESCRIPTION:

BRIEF SUMMARY
The invention relates to an equipment case with a metallic casing, which has a parallelepipedic casing jacket, as well as a front and a back, at least the front being constructed as a cover or lid. The equipment case is provided with an inner frame, which is fixed by means of vibration-damping elements in spaced manner to the casing jacket and surrounds a reception space for equipment and components.


BACKGROUND OF THE INVENTION

Equipment cases serving as a portable protective casing for electrical and electronic equipment are known and are e.g. described in 0 327 809 A2.
As the equipment is generally used in the military and research fields and must be able to withstand very high mechanical, thermal and other extreme environmental influences, the parallelepipedic or box-like equipment case has a self-supporting, metallic casing with a vibration-resistant casing jacket, a front cover and a back. The back can also be constructed as a cover. Within the casing jacket and spaced therefrom is provided an inner frame with a normally standardized reception space for the equipment and components and which is fixed by means of vibration-damping elements. In the case of the protective casing described in EP 0 327 809 A2 the inner frame is e.g. suspended by means of eight vibration dampers in the angle areas of the casing jacket.
A disadvantage of the hitherto known equipment cases is their relatively complicated and expensive manufacture. For example, the four plate parts of the casing jacket are generally welded together. In order to be able to obtain an electrical shielding (HF-seal), additionally on the cover-side end regions of the casing jacket and on the inner frame, there are flanges or marginal sections for receiving circumferential seals. Manufacture is relatively complicated and costly due to the large number of individual parts, which also means that storage must take place in a particularly easily monitorable manner. In addition, the numerous components and manufacturing steps constitute sources of error, which have a negative effect on the protective function of the equipment case.


SUMMARY OF THE INVENTION

The object of the invention is to provide an equipment case, whose construction ensures high functionality and at the same time permits simple, cost-effective manufacture.
According to the invention the casing jacket, which has a base surface, cover surface and side surfaces, is made from a one-piece, metallic flat material. Between the side or lateral surfaces and the adjacent cover surface, as well as between the side or lateral surfaces and the adjacent base surface is in each case constructed a corner or angle bevel for the vibration-damping reception of an inner frame. On the front and back the casing jacket has a circumferential front or back hollow section, which is formed from the one-piece flat material.
A fundamental idea of the invention is to achieve through an integral construction a functional combination in such a way that the number of individual components and the manufacturing steps are reduced and consequently the manufacture of the equipment case can be made more effective. Apart from the manufacturing and cost advantages a high stability and use value increase of the equipment case is achieved, which is in particular due to an improved design, a protected fitting of closures, handles, etc. and a particularly high accessory adaptation.
According to the invention the casing jacket of the metallic, self-supporting casing, which is generally parallelepipedic or box-like, is made from a single part, so that a reduction of components and manufacturing steps is possible.
The blank part of the casing jacket constructed as one-piece flat material undergoes a bending process. A base surface, a cover surface, two vertical side parts and angle bevels located between said casing jacket areas are formed preferably as 45.degree. bevels.
Advantageously only a single connection or joint, e.g. a weld is required, so as to connect the one-piece casing jacket after the bending process. Another a
