Joachim Klinner, Hauptstr. 43, 74391 Erligheim Distribution cabinet with a distribution frame

The invention relates to a distribution cabinet with a distribution frame according to the preamble of claim 1.

Such distribution cabinets are well known. Angle plates are usually provided to secure the distribution frame in the distribution cabinet, using which the distribution frame is screwed into the distribution cabinet. Pre-assembly is usually carried out in the company. The distribution frame is then removed on site, the cables are pulled in and the distribution frame is then reinstalled in the distribution cabinet. Two workers are usually required for this. A particular disadvantage of the well-known distribution cabinets with distribution frames is that assembly is quite complex, which results in high labor costs.

It is therefore the object of the present invention to provide a system that is as simple as possible and for the installation of which preferably only one worker is required. Furthermore, the installation should be uncomplicated.

This object is achieved by a distribution cabinet with a distribution frame according to the features of claim 1.

The installation and removal of distribution frames in distribution cabinets is made significantly easier by the elements described in claim 1. The distribution frame can be hung or inserted directly into the elements, so that the correct position and subsequent screwing of the distribution frame in the distribution cabinet is no longer necessary. Furthermore, the longer distribution frame enables an 11 to 13% higher packing density, which means that the installation space of the distribution cabinet can be better utilized.

The elements for installing the distribution frame can be integrated directly into the rails running to the rear. Alternatively, the elements can be attached to the rails on or at the side. This can be done by screwing, clamping, gluing or welding, for example.

The system is particularly flexible because the rails and/or the elements are made of profile strips with regularly recurring side openings. This means that the distribution frame can be moved almost as desired without having to drill new holes.

The elements are preferably attached to the open side of the rails. Depending on the space available in the distribution cabinet, the elements can be attached on or to the side of the horizontally downward-running rails.

If the distribution cabinet is to be transportable, a safety device can be provided on the elements to prevent the distribution cabinet from accidentally slipping out of the elements. The safety device can be, for example, a clamping screw, a pin or a latch that fixes the cross rail in the element.

In the following, the invention is described using an embodiment with reference to the accompanying drawings. They show

Fig. 1 is a simplified representation of the embodiment and Fig. 2 is an enlarged section of Fig. 1 without distribution frame.

Fig. 1 shows a schematically illustrated distribution cabinet 1, the walls and door of which are not shown. A distribution frame 2 is installed in the distribution cabinet 1. The distribution frame 2 has several cross rails 4 and longitudinal rails 6, which are connected to one another by means of screw connections 8. System strips and separating strips as well as cable guides can be arranged on the distribution frame 2 in a known manner.

Rails 12 running horizontally to the rear are arranged on the side walls 10 of the distribution cabinet 1, for example fastened to the distribution cabinet 1 using screws (not shown). An element 16 is arranged on each of the rails 12 at a slight distance from the rear 14 of the distribution cabinet 1. The element 16 is fastened to the rail 12 using a screw connection (not shown). The element 16 rests on the open side of the C-profile of the rails 10. In the exemplary embodiment, this side faces inwards; an upward-facing version is also possible if there is sufficient space in the distribution cabinet.

The element 16, which is shown enlarged in Fig. 2, is a U-shaped profile rail. The two legs 18 of the element 16 are bent out by 90° approximately halfway so that they rest on the rail 12. Due to its design, the element 16 offers a receptacle 20 for the cross rail 4 of the distribution frame 2. The cross rail 4 can be attached to the element 16 by a screw connection (not shown).

Claims (11)

-01 - Claims: 1. Distribution cabinet (1) with a distribution frame (2) which has a plurality of longitudinal rails (6) and transverse rails (4) connected to one another, characterized in that in the distribution cabinet (1) two elements (16) for installing the distribution frame (2) are provided at the same height, which are arranged directly or indirectly on the side walls of the distribution cabinet and which are open upwards and to the side on which the corresponding element (16) is arranged. 2. Distribution cabinet according to claim 1, characterized in that one or more cross rails (4) of the distribution frame (2) are inserted into the elements (16). 3. Distribution cabinet according to claim 1 or 2, characterized in that in the distribution cabinet (1) rails (12) are arranged perpendicular to its front, on which the elements (16) for installing the distribution frame (2) are arranged or in which the elements (16) are integrated. 4. Distribution cabinet according to one of the preceding claims, characterized in that the rails (12) and/or the elements (16) are sections of a U- or C-shaped profile rail with regularly recurring lateral openings. 5. Distribution cabinet according to one of the preceding claims, characterized in that the elements (16) are attached to the open side of the rail (12). -02- 6. Distribution cabinet according to one of the preceding claims, characterized in that the open side of the rail (12) is directed horizontally inwards into the distribution cabinet (1). 7. Distribution cabinet according to one of claims 1 to 5, characterized in that the open side of the rails (12) is directed upwards. 8. Distribution cabinet according to one of the preceding claims, characterized in that a safety device is arranged on the elements (16). 9. Distribution cabinet according to claim 8, characterized in that the securing device is a clamping screw. 10. Distribution cabinet according to claim 8, characterized in that the safety device is a pin. 11. Distribution cabinet according to claim 8, characterized in that the safety device is a latch.
