BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a rack for a switching cabinet with horizontal depth and length struts to which vertical frame legs are attached in corner areas with corner connections and wherein the corner connection has a compensating piece.
2. Description of Prior Art
Such a rack is known from French Patent Reference FR 2 674 581.
The rack shown in this document has a lower and upper frame. In the corner areas of the lower and upper frame vertical frame profiles can be attached. For this attachment, corner connectors are used. The corner connectors have three plug inserts, each vertical to the others. The horizontal depth and length struts as well as the vertical frame legs are pushed onto these plug inserts. For the fixation of a vertical frame leg two clamp elements are used. The clamp elements have interlocking projections and can be screwed onto the plug insert whereby the interlocking projections stand out over the outer geometry of the plug insert. The vertical frame profile has two recesses which are formed and adapted in their geometry to the interlocking projections. On pushing the vertical frame profile onto the plug insert the clamp elements are initially swiveled out and then snap behind the recesses so that the vertical frame profile is compressed onto an impact face of the corner connector with its front side.
Varying demands are made on switching cabinets. The vertical frame legs in particular must be formed adapted thereto. Thus, for example, various cross-sections are used for frame legs which are suitable for various possible designs.
Adapted switching cabinets have been conceived for these varying possible applications whereby a high expenditure is required.
For example, in German Patent Reference DE 41 35 108 a corner connector is known in which three projections perpendicular to one another are mounted on a base body. The individual frame legs and length and depth struts can be pushed onto the projections.
Another corner connector is described in German Patent Reference DE 44 39 624. A base body is also used on which two projections stand out for each frame leg and each length and depth strut. The projections are plugged into hollow chambers, for example of the frame leg.
SUMMARY OF THE INVENTION
It is one objective of this invention to provide a switching cabinet of the type mentioned initially which offers in a simple manner flexibility for varying possible applications.
This objective is accomplished with optional differently structured vertical frame legs which can be attached and the open spacing between neighboring vertical frame legs determined by compensating pieces.
With this development it is possible for inserts each with a varying insert width to be affixed between the vertical frame legs. This makes it possible to prepare racks that can be adapted to various systems of measurement without great expenditure. For example, a rack which is designed in the metric system can be modified simply so that 19" units can be introduced between the vertical frame legs. With this simple measure a great flexibility in switching cabinets can be made possible.
According to a development of this invention, the depth and length struts are formed as hollow profiles which have openings for vertical inserts in the corner areas of the rack and the compensating pieces can be introduced into the openings.
In the case of such developments of a rack, inserts as well as compensating pieces can be introduced into the openings. The compensating pieces can vary independently of the cross-sectional geometries of the vertical frame leg. The insert itself can also be structured variably.
According to a simple development of this invention the length and depth struts have the same cross-sectional form and are bent from one section of sheet metal so that the length and depth struts have a horizontal cover section to which an angled section running parallel to the outer side of the rack adjoins, to which a perpendicular fold directed inwards adjoins.
