Description

GERMAN

The invention relates to an arrangement for fastening of racks and office building material in rack frames with housing construction for telecommunications, in particular Telephony and allows a particularly simple and economical assembly of the rows of frames to.

When building rows of frames for telephone systems, the procedure so far has been that the components belonging to the row of frames, such as cable grids, selector frames, feet, etc., were attached to the frame by means of screws and holes in the frame. Since the pre-drilled mounting holes in the rack frame often do not match those on the rack, this results in considerable installation costs. This can also be seen when changing frames of different widths. Must be implemented during installation or conversions frames, you will in the \ ^r ielzahl of cases new fixing distances and new holes, el. E., The time spent planning costs doubled. This applies both to the fastening of the frames and to that of the official building material, such as cable grids, frame supports, struts and feet.

In order to take these circumstances into account, in a known manner parallel to the upper and lower angular rack rails and at a certain distance from one leg of the rack rails in addition in each case a longitudinal rail with a flat cross-section is arranged. As a result of the thigh and the intermediate space formed by the longitudinal rail, the rack inserts can now be released after loosening move the fastening screws as desired. Aside from the hassle of this extra, don't Longitudinal rails that belong directly to the frame are used for stiffening when the frame is not fully occupied the rail arrangement as well as compliance with de-; Distance adjustable connecting straps provided.

If you also wanted to proceed in the manner described above when attaching official material, the effort driven would increase even more.

There is also an arrangement for fastening racks in the rack frame, in which the racks both above and below by means of clamping devices suspended in the longitudinal beams of the rack frame are clamped to the frame.

Apart from the fact that this attachment requires a special device, which also does not belongs directly to the frame, the use of this type of fastening is only on the one between the frames 1> limited space, d. i.e., a subsequent change or postponement arrangement

the attachment along the rack frame is only possible if all racks are evenly positioned Amount can be shifted in this direction. This can be used as a type of fastening for official building material Do not use the facility either.

With the invention, the disadvantages described are avoided and a new construction for rows of frames created.

The invention is characterized in that the L-shaped frame rails and the rails of the Gestellrahmen.s at the same time serve as a fastening means and the frame is hung on the frame is. that the lower frame rail with the angled opening on one leg end of the corresponding also L-shaped rail of the rack and the long legs of the upper Rack rail and the corresponding rail of the rack frame lying next to one another by means of a screw> e are locked and the office building material and the feet are permanently assigned to double angles, which together allow attachment to the top and bottom rails of the rack frame with a screw.

According to the invention, the upper and lower longitudinal rails of the frame for receiving the Selector and relay sets are used at the same time as fastening means for the frame on the frame, or the fasteners are permanently assigned to the components. The procedure here is so that the lower, im Cross-section L-shaped longitudinal rail of the frame with

the angled opening on one leg end of the lower rail, which is also L-shaped in cross-section of the rack frame and the upper longitudinal rail of the rack with one of its legs against one leg of the upper, in cross-section L-shaped rail of the rack frame rests and with the help of the Roof of the rear housing is locked from a screw on the rack frame. Here it is just necessary to provide a hole in the upper longitudinal rail of the frame and in the roof of the rear housing. The previously usual holes in the rack frame are no longer necessary. The fastening of the office building material to the frame is carried out in accordance with the Concept of the invention by means of a double angle profile permanently assigned to the office building material, its an angle opening also rests on one leg end of the upper rail of the rack frame. Double angle profile along with office building material are by means of one through the leg of the second angle the screw going through the double angle profile pulled tightly against the cross-sectionally L-shaped rail of the rack frame.

For fastening the lower rail of the rack frame The same procedure is used for the frame feet as for fastening the office building material on the top rail of the rack frame, d. i.e., the other leg end of the lower one, in cross section L-shaped rail of the rack frame lies in one angle opening of a double-angle profile that is also permanently assigned to the component in question, in this case the frame base.

The attachment of the lower rail of the rack frame on the frame feet is also carried out by means of a through the leg of the second angle of the Double angle through-going screw that, when tightened, the rail into the opening of the former Angle presses.

An exemplary embodiment according to the invention is illustrated in the drawing.

As can be seen, the fasteners are 1 (lower rack rail), 2 (upper rack rail), 4 and 5 (Double angle) themselves parts of the frame or are the corresponding to be attached to the frame 6, 7 Components 8 (front housing), 9 (rear housing), (office building material) and 11 (frame base) directly assigned.

The screws 3, 12 and 13 are used for the final Determination of the location of the frame, the feet and the office building material.

With the invention it is achieved that all components to be fastened to the rack frame at any one Place of the rack frame, fixed without prior definition of drill holes and at any time the mounting location on the rack frame can be changed. Likewise, the exchange of frames, without making changes to the frame, now easily possible. Assembly and design work are therefore considerably simplified, all the more so than the rack frame before the racks or the housing arrives at the installation site and can be installed completely.
