Abstract

An arrangement of a switch cabinet base and a switch cabinet frame rack mounted thereon, wherein the switch cabinet base includes a plurality of base corner pieces fixed to the switch cabinet frame rack, and the switch cabinet frame rack including a plurality of profile struts, at least one profile strut of which includes a first mounting side with a row of holes of first mounting receptacles, and wherein at least one of the base corner pieces has a second mounting side with a row of holes of second mounting receptacles, wherein the first and second mounting receptacles are spaced apart by the same grid dimension.

First claim

The invention claimed is:

1. A switch cabinet assembly comprising:
a switch cabinet base and a switch cabinet frame rack mounted thereon;
wherein:
the switch cabinet base includes a plurality of base corner pieces fixed to the switch cabinet frame rack;
the switch cabinet frame rack includes a plurality of profile struts, at least one profile strut of which comprises a first mounting side with a row of holes of first mounting receptacles;
at least one of the base corner pieces comprises a second mounting side with a row of holes of second mounting receptacles, the first and second mounting receptacles are spaced apart by the same grid dimension; and
the row of holes of the second mounting receptacles extends vertically.

2. The switch cabinet assembly according to claim 1 , in which at least one of the following conditions is met:
a. the first and the second mounting side are arranged in the same plane;
b. the first mounting receptacles form a first system perforation of mounting receptacles regularly spaced apart by the grid dimension and the second mounting receptacles form a second system perforation of mounting receptacles regularly spaced apart by the grid dimension;
c. the first mounting receptacles form a first row of holes of mounting receptacles regularly spaced apart by the grid dimension and the second mounting receptacles form a second row of holes of mounting receptacles regularly spaced apart by the grid dimension, wherein the two rows of holes are spaced apart from each other by the grid dimension or an integer multiple of the grid dimension.

3. The switch cabinet assembly according to claim 1 , which further comprises an interior installation component, which
a. is fixed with a first fastening section in a volume enclosed by the switch cabinet frame rack and with a second fastening section in a volume enclosed by the switch cabinet base, or
b. is mounted with a first fastening section via one of the first mounting receptacles on the first mounting side of the profile strut, and which is fixed with a second fastening section via one of the second mounting receptacles on the second mounting side of the base corner piece, or
c. is fixed with a first fastening section via one of the second mounting receptacles to the second mounting side of the base corner piece, and which is fixed with a second fastening section via one of the second mounting receptacles to the second mounting side of another of the base corner pieces, wherein the two rows of holes of the second mounting receptacles of the corner pieces have a distance to each other which corresponds to an integer multiple of the grid dimension.

4. The switch cabinet assembly according to claim 3 , in which the first fastening section of the interior installation component has a first fastening means and the second fastening section of the interior installation component has a second fastening means, wherein the fastening means comprise a distance which is an integer multiple of the grid dimension to each other.

5. The switch cabinet assembly according to claim 1 , in which two of the base corner pieces of the switch cabinet base are each arranged facing each other with an outer wall, wherein the outer walls each comprise the second mounting side comprising the second mounting receptacles, and wherein the outer walls are arranged at a distance from each other which corresponds to an integer multiple of the grid dimension.

6. The switch cabinet assembly according to claim 1 , in which each one of the plurality of base corner pieces includes a sheet metal shaped part, which has a first and a second outer wall which extend perpendicular to each other, and which further has an upper cover side and a lower bottom side which are arranged parallel to each other and perpendicular to the outer walls, wherein the outer walls, the cover side and the bottom side delimit an interior space of the base corner piece which is open towards a corner of the sheet metal shaped part.

7. The switch cabinet assembly according to claim 6 , in which each one of the plurality of base corner pieces includes a plastic inlay, which extends in the interior space between the cover side and the bottom side and which at its end in front of the cover side has a receptacle which is open towards the cover side, in which receptacle a threaded nut is accommodated in a rotation-proof manner.

8. The switch cabinet assembly according to claim 7 , in which the plastic inlay is releasably connected to the sheet metal shaped part in a mounting position in the interior space.

9. The switch cabinet assembly according to claim 6 , in which a threaded passage of a threaded nut is aligned with an opening through the cover side and accessible via the opening.

10. The switch cabinet assembly according to claim 6 , in which the cover side has a trough-shaped recess for the positive reception of a sliding skid, wherein an opening through the cover side is arranged in the recess, which is aligned with a threaded passage of a threaded nut.

11. The switch cabinet assembly according to claim 6 , in which the outer walls each have a first U-edging at their free longitudinal edge, with a first profile side extending perpendicularly to the outer wall and a second profile side formed on the first profile side, which extends parallel to the outer wall and has a free edge arranged in the interior space.

12. The switch cabinet assembly according to claim 11 , in which the first U-edgings comprises the second mounting side on at least one of the first and second profile side.

13. The switch cabinet assembly according to claim 11 , in which an inlay has a first and a second pair of guide pins spaced apart, the first pair of guide pins with its free ends abutting the second profile side of a first one of the two U-edgings, and wherein the second pair of guide pins with its free ends abutting the second profile side of a second of the U-edgings.

14. The switch cabinet assembly according to claim 13 , in which the inlay also has a first and a second pair of latching pawls pre-tensionable against each other, and which extends with its free end between one of the pairs of guide pins each towards and parallel to the respective second profile side.

15. The switch cabinet assembly according to claim 11 , in which a base panel can engage around one of the two U-edgings with a fastening tab, wherein a free end of the fastening tab extends perpendicularly to the panel front, abuts against the second profile side of one of the first U-edgings and is fixed to the second profile side.

16. The switch cabinet assembly according to claim 15 , in which the free end of the fastening tab has an undercut clearance on an edge facing the interior space, in which undercut clearance a pair of latching pawls engages.

17. The switch cabinet assembly according to claim 11 , in which the interior space of the base corner piece is closed off by a corner panel which abuts parallel to the first profile sides of the first U-edgings and engages one of the two free edges of each of the two second profile sides with a latching hook.

18. The switch cabinet assembly according to claim 11 , in which the two first profile sides of the first U-edgings and the two second profile sides of the first U-edgings are aligned perpendicular to each other.
