DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a switching cabinet with a rack having horizontal and vertical frame profiles, where the horizontal frame profiles form a lower and an upper frame and the vertical frame profiles are attached in comer regions of the lower and the upper frame, where the vertical frame profiles are symmetrical to cross-sectional diagonals running across the virtual vertical outer edges of the rack, where the vertical frame profiles which are turned toward an inside of the switching cabinet have an open inner cavity, where vertical assembly rails can be mounted in the inner cavity, where one profiled side standing perpendicular to the outside of the rack is joined to the inner walls, and where the inner walls, the assembly rails and the profiled sides can be fitted with rows of fastening cavities inserted according to a division grid.
2. Description of Prior Art
In one known switching cabinet, the rack has twelve of the same frame profiles which meet each other orthogonally in the frame corner regions. The frame profiles have two inner walls which are aligned parallel to the associated sides of the rack. Profiled sides protrude from the inner walls and are positioned at a right angle to the side of the rack. Thus the inner walls and the profiled sides form a vertical, inner edge facing the interior of the switching cabinet. Assembly rails can be attached to the frame profiles for mounting fixtures in the interior of the switching cabinet. The assembly rails are designed as enclosed hollow profiles and feature two contact sides at a right angle. The other two sides are used as assembly sides and each has a row of attachment cavities.
The assembly rails rest on contact sides against the inner walls of the frame profile and are attached here; for example, they are welded or screwed. The two assembly sides face the interior of the switching cabinet.
SUMMARY OF THE INVENTION
It is one object of this invention to provide a switching cabinet of the type mentioned above, which offers great variability for the attachment of fixtures.
The object is achieved with inner walls and profiled sides having rows of attachment cavities incorporated in a division grid.
In its basic version without the mounting rails, this switching cabinet allows the attachment of fixtures to the attachment cavities of the frame profile. The use of four rows of attachment cavities offers great versatility in assembly. One inner wall and the profiled side attached thereto are always allocated to a back side or a front side of the switching cabinet. The other inner wall is allocated to the profiled side of the associated switching cabinet. This configuration makes it possible to allocate fixtures individually to the front, the back or the side. For example, wall elements standing parallel to the back and in addition to one side, can be attached to the inner walls in order thus to form insulating walls or air inlet shafts.
As a result of the use of assembly rails, the versatility of the attachment can be even further increased. In particular, the formation of one or more rows of attachment cavities can be varied with regard to their division grid in comparison to the frame profile. Thus, the points of attachment can be varied at random along the frame profile. The variation of the division grid also provides the potential to form a switching cabinet in a simple manner, with combined metric and inch-based dimensions. For example, the attachment cavities of the frame profile can be spaced metrically, and those of the assembly rails can be spaced in inches.
According to one preferred embodiment of this invention, the vertical frame profiles pass at their profiled sides into sealing surfaces running parallel to the side surfaces of the rack. At these flat profiled sections, side walls, one back wall and/or one cabinet door can be installed to form a seal. Due to the use of these sealing surfaces, good sealing action can be achieved. In particular, the attachment of HF-seals are easily p
