Abstract

The invention relates to a mounting plate arrangement with a switch cabinet frame and a mounting plate fastened thereto via at least one mounting plate holder, wherein the switch cabinet frame has a rectangular floor frame with four profile struts, which has on its outer side a fastening section offset relative to an outer sealing plane of the switch cabinet frame relative to the interior of the switch cabinet frame, wherein the mounting plate holder is formed in multiple parts, with a support bracket and with a base connected to the support bracket, wherein the support bracket is connected to the fastening section and to the mounting plate and the mounting plate stands on the base, and wherein the mounting plate holder with the base is placed on a profile side of one of the four profile struts extending between the sealing plane and the fastening section.

First claim

The invention claimed is:

1. A mounting plate arrangement with a switch cabinet frame and a mounting plate fastened thereto via at least one mounting plate holder, comprising wherein the switch cabinet frame has a rectangular floor frame with four profile struts, which has on its outer side a fastening section offset relative to an outer sealing plane of the switch cabinet frame relative to the interior of the switch cabinet frame, wherein the mounting plate holder is formed in multiple parts, with a support bracket and with a base connected to the support bracket, wherein the support bracket is connected to the fastening section and to the mounting plate and the mounting plate stands on the base, and wherein the mounting plate holder with the base is placed on a profile side of one of the four profile struts extending between the sealing plane and the fastening section.

2. The mounting plate arrangement according to claim 1 , in which the support bracket is connected to the base via a plug connection.

3. The mounting plate arrangement according to claim 1 ,
in which the base has a passage through which the support bracket extends with a fixing tab between opposite sides of the base,
the mounting plate being fixed to the fixing tab.

4. The mounting plate arrangement according to claim 1 , in which the support bracket has an L-shaped section, with which it embraces the fastening section.

5. The mounting plate arrangement according to claim 1 , in which the base rests with a support side on an L-shaped section of the support bracket with which it embraces the fastening section, wherein the mounting plate stands on the support side with a front face of an edging on its outer circumference.

6. The mounting plate arrangement according to claim 1 , in which the base has a spacer and a support side, the support bracket extending through the support side with a fixing tab, and the mounting plate being fixed to the fixing tab.

7. The mounting plate arrangement according to claim 6 , in which the support side has a first opening and a L-shaped section of the support bracket, with which the support bracket embraces the fastening section, has a second opening and the fastening section has a third opening, the three openings being aligned and a fastener, in particular a threaded bolt, passing through the aligned openings.

8. The mounting plate arrangement according to claim 1 , in which the mounting plate has an edging on a vertical outer circumference, in particular a C-edging or an U-edging, with a first mounting profile side arranged in a mounting plane of the mounting plate and a reinforcing profile side spaced therefrom perpendicularly to the mounting plane, wherein
a) in a first mounting position, the mounting plate rests against and is fixed to a fixing tab of the support bracket via the mounting profile side, and/or
b) in a second mounting position, the mounting plate can rest against and be fixed to a fixing tab of the support bracket via the reinforcing profile side.

9. The mounting plate arrangement according to claim 8 , in which in the first mounting position, the mounting profile side is aligned with an inner fastening profile side of the fastening section facing the interior of the switch cabinet frame and/or, in the second mounting position, the mounting profile side is aligned with an outer fastening profile side of the fastening section facing the sealing plane.

10. The mounting plate arrangement according to claim 1 , in which the support bracket comprises a first material and the base comprises a second material different from the first material, the modulus of elasticity of the first material being larger than the modulus of elasticity of the second material.

11. The mounting plate arrangement according to claim 10 , in which the first material is a metal, in particular a steel, and the second material is a plastic, in particular a thermoplastic and preferably a polyamide.

12. The mounting plate arrangement according to claim 1 , in which the support bracket is a Z-profile, having an L-shaped section with which the support bracket embraces the fastening section, and having a fixing tab which merges into the L-shaped section via a 90° bend and has a fourth opening which is aligned with another opening in an edging on the outer circumference of the mounting plate.

13. The mounting plate arrangement according to claim 10 , in which the base has a spacer with which the base stands on the profile side of the profile strut, and a support side with which the mounting plate holder projects over a horizontal fixing profile side of the fastening section, wherein a passage is arranged through the base, through which the support bracket extends with a fixing tab, in a transition between the spacer and the support side and the support bracket rests against the spacer with its fixing tab adjacent to the 90° bend.

14. A method for mounting a mounting plate arrangement, which comprises the steps:
providing a switch cabinet frame with a rectangular floor frame with four profile struts, wherein the floor frame has on its outer side a fastening section offset relative to an outer sealing plane of the switch cabinet frame to the interior of the switch cabinet frame;
providing a mounting plate and a mounting plate holder which is formed in multiple parts and comprises a support bracket and a base releasably connected to the support bracket;
mounting the mounting plate holder on the mounting plate by fixing a fixing tab of the support bracket to an edging on a vertical outer edge of the mounting plate so that a front face of the edging rests on the base; and
placing the mounting plate via the base on a profile side of one of the four profile struts extending between the sealing plane and the fastening section and, if necessary, swiveling the mounting plate until a mounting plane of the mounting plate is brought into the vertical.

15. The method according to claim 14 , in which providing the mounting plate holder comprises connecting the support bracket to the base by pushing the fixing tab of the support bracket through the base via a passage of the base until an L-shaped section of the support bracket rests against a support side of the base.

16. The method according to claim 14 , in which placing the mounting plate comprises placing the mounting plate via the outer side of the floor frame and/or via the outer sealing plane of the switch cabinet frame.

17. The method according to claim 14 , in which after placing the mounting plate, the mounting plate is removed via an inner fastening profile side of the fastening section facing the interior of the switch cabinet frame.
