Abstract

A mounting frame for a switchgear cabinet or a rack includes mounting pieces which are arranged, as corner pieces, in the four corner sections of a rectangle or square that extends in an x-y plane, the mounting pieces being produced in a respective shaping process and having outer first and second mounting faces which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, and are provided with hollow spaces which are at least partially surrounded by wall parts and/or bores that are oriented in the z direction. The mounting frame further includes intermediate elements which extend between the mounting pieces in the x direction and in the y direction and the end sections of which are fastened to the mounting pieces. The mounting pieces have wall sections which extend in parallel to the x-y plane, thus making assembly easier.

First claim

The invention claimed is:

1. A mounting frame for a switchgear cabinet or a rack, comprising
mounting pieces which are arranged, as corner pieces, in the four corner sections of a rectangle that extends in an x-y plane, said mounting pieces being produced in a respective shaping process and having outer first and second mounting faces which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, and are provided with hollow spaces which are at least partially surrounded by wall parts or bores that are oriented in the z direction, and comprising intermediate elements which extend between the mounting pieces in the x direction and in the y direction and the end sections of which are fastened to the mounting pieces,
wherein the mounting pieces have wall sections which extend in parallel to the x-y plane and terminate in z-direction in a first and a second base face oriented in the x-y-plane, the second base face being parallel and spaced apart from the first base face by a distance,
wherein the base faces form the outer face of at least a first and at least a second base wall section, the first and second base wall sections being parallel to and spaced apart from one another in the z direction,
wherein the mounting faces are spaced apart from one another at their facing ends to define a first corner space in a first corner region,
wherein the first base wall section comprises at least one bore, and the second base wall section comprises at least one bore, and the at least one bore in the first base wall section are aligned with the at least one bore in the second base wall section,
the first corner space being further defined by first and second corner region bordering walls, each of said first and second bordering walls defining a plane, wherein the plane of the first bordering wall is perpendicular to the plane of the second bordering wall,
the corner region bordering walls being connected to one another and perpendicularly oriented with respect to each other in the z direction, with each of the corner region bordering walls being connected to and perpendicularly oriented with respect to each of the first and second base wall sections, and
wherein the first corner space is confined in the z direction by the first and second base wall sections.

2. The mounting frame of claim 1 , wherein at least one base face comprises receiving structures adapted to a facing section of a framework or a rack or that adapter elements are provided which, on one side thereof, are adapted to the receiving structures of the base face and, on the opposite side, are provided with adapter structures mating the facing section of the framework.

3. The mounting frame of claim 2 , wherein the adapter elements comprise adapter plates.

4. The mounting frame of claim 2 , wherein the receiving structures comprise formed protrusions on the base face which comprises the receiving structures.

5. The mounting frame of claim 2 , wherein the receiving structures comprise first and second receiving chambers which are oriented perpendicularly to the first space direction (z) and parallel to the associated mounting face and which are at least partly surrounded by wall sections running in their orientation direction.

6. The mounting frame of claim 5 , wherein intermediate elements are inserted into the receiving chambers.

7. The mounting frame of claim 6 , wherein the intermediate elements comprise mounting rails having at least one row of holes or a rail having C-shaped cross section.

8. The mounting frame of claim 1 , wherein the bores are provided with internal threads or with thread inserts.

9. The mounting frame of claim 1 , comprising additional corner region bordering walls and wherein the mounting pieces comprise further perpendicularly connected wall sections at the interior of the ends of the first and the second mounting face facing away from one another, which wall sections are integrally connected to one another, and that the further wall sections leave a second corner space between their facing ends, which is laterally confined by the additional corner region bordering walls lying parallel to neighboring mounting faces and oriented in z direction and by the first and second base wall section in z direction.

10. The mounting frame of claim 1 , wherein the mounting frame comprises lateral covers and corner covers made of plastics or metal that are positioned laterally and in the corner region and which are supported at the mounting piece or at a mounting rail.

11. The mounting frame of claim 1 , wherein the mounting piece is formed as a plastic molded part.

12. The mounting frame of claim 1 , wherein the at least one bore in the first base wall section and the at least one bore in the second base wall section are aligned vertically.

13. The mounting frame of claim 1 , wherein the at least one bore in the first base wall section and the at least one bore in the second base wall section are located in the first corner space.

14. A method of forming a switchgear cabinet or a rack which comprises utilizing the mounting frame of claim 1 as a socket or intermediate frame of the switchgear cabinet or the rack.

15. A corner piece for a mounting frame for a switchgear cabinet or a rack, wherein corner pieces are arranged in the four corner sections of a rectangle that extends in an x-y plane, the corner pieces being produced in a respective shaping process and having outer first and second mounting faces which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, and are provided with hollow spaces which are at least partially surrounded by wall parts that are oriented in the z direction, and comprising intermediate elements which extend between the mounting pieces in the x direction and in the y direction and the end sections of which are fastened to the corner pieces, the corner piece comprising:
wall sections which extend in parallel to the x-y plane and terminate in the z-direction in a first and a second base face oriented in the x-y-plane, the second base face being parallel and spaced apart from the first base face;
a portion of the first base face forming a first base wall section, and a portion of the second base face comprising a second base wall section, the first and second base wall sections being parallel to and spaced apart from one another;
the corner piece further comprising first and second corner region bordering walls, each of said first and second bordering walls defining a plane, wherein the plane of the first bordering wall is perpendicular to the plane of the second bordering wall;
the corner region bordering walls being connected to one another and perpendicularly oriented with respect to each other, with each of the corner region bordering walls being connected to and perpendicularly oriented with respect to each of the first and second base wall sections; and
the corner region bordering walls and the first and second base wall sections defining a first corner space;
wherein the first base wall section comprises at least one bore, and the second base wall section comprises at least one bore, and the at least one bore in the first base wall section are aligned with the at least one bore in the second base wall section, and
wherein the first corner space is confined in the z direction by the first and second base wall sections.
