Abstract

A switchgear cabinet system, which is assembled from switchgear cabinet units strung together in a row, each switchgear cabinet unit comprising a rack which is made up of frame profiles, in which at least the vertical frame profiles have the following features: the frame profile is mirror symmetrical with respect to a cross-sectional diagonal; the frame profile has profile sides that form the outer sides of the rack; projecting outward from the profile sides are profile projections, each extending outward from one of the profile sides; when two racks are strung together, corresponding profile projections of two frame profiles are situated mirror symmetrically opposite one another in each case, leaving a gap between the end faces of the profile projections, which is closed by a seal, characterized in that the seal is a push-on seal that is seated on at least one of the opposing profile projections.

First claim

The invention claimed is:

1. A switchgear cabinet system comprising:
a plurality of switchgear cabinet units strung together in a row, each switchgear cabinet unit comprising a rack which is made up of vertical frame profiles, wherein each of the vertical frame profiles is mirror symmetrical with respect to a cross-sectional diagonal and has profile sides that form the outer sides of the rack and two hollow chambers which are connected by a connecting bridge and projecting outward from the profile sides are profile projections, each extending outward from one of the profile sides;
wherein the profile sides comprise two profile side segments that merge into one another and are angled such that a first profile side segment of a first profile side extends perpendicular to a first profile side segment of a second profile side, and a second profile side segment of the first profile side extends parallel to a second profile side segment of the second profile side;
wherein when two racks are strung together, corresponding profile projections of two vertical frame profiles are situated mirror symmetrically opposite one another in each case, leaving a gap between the end faces of the profile projections, which is closed by a seal, said seal being a push-on seal which is seated on at least one of the opposing profile projections and which has at least two legs located opposite one another, between which a gap is formed, the width of which is less than or equal to the width of the profile projection of a selected vertical frame profile,
and wherein a bridge that connects the opposing legs of the push-on seal has a curved concave bearing surface which is wider than the thickness of the profile projection of the vertical frame profile to be attached there, and the opposing legs of the push-on seal have different lengths or widths.

2. The switchgear cabinet system according to claim 1 , wherein each of the profile projections extends perpendicularly from a respective profile side.

3. The switchgear cabinet system according to claim 1 , wherein each of the profile projections extends at an angle of substantially 135° in relation to the bridge.

4. The switchgear cabinet system according to claim 1 , wherein between the two hollow chambers, bordering the connecting bridge, a dovetail groove is formed, which is symmetrical with respect to the cross-sectional diagonal.

5. The switchgear cabinet system according to claim 1 , wherein between the two hollow chambers, bordering the connecting bridge, a third hollow chamber is formed.

6. The switchgear cabinet system according to claim 2 , wherein each of the profile projections extends at an angle of substantially 135° in relation to a bridge between the profile projections.

7. The switchgear cabinet system according to claim 1 , wherein each of the vertical frame profiles comprises two profile projections that extend perpendicularly to each other.

8. The switchgear cabinet system according to claim 1 wherein at least one of the profile projections is formed by a portion that is folded back onto itself.

9. A switchgear cabinet system comprising:
a plurality of switchgear cabinet units strung together in a row, each switchgear cabinet unit comprising a rack which is made up of vertical frame profiles, wherein each of the vertical frame profiles is mirror symmetrical with respect to a cross-sectional diagonal and has profile sides that form the outer sides of the rack and two hollow chambers which are connected by a connecting bridge and projecting outward from the profile sides are profile projections, each extending outward from one of the profile sides;
wherein the profile sides comprise two profile side segments that merge into one another and are angled such that a first profile side segment of a first profile side extends perpendicular to a first profile side segment of a second profile side, and a second profile side segment of the first profile side extends parallel to a second profile side segment of the second profile side;
wherein when two racks are strung together, corresponding profile projections of two vertical frame profiles are situated mirror symmetrically opposite one another in each case, leaving a gap between the end faces of the profile projections, which is closed by a seal, said seal being a push-on seal which is seated on at least one of the opposing profile projections and which has at least two legs located opposite one another, between which a gap is formed, the width of which is less than or equal to the width of the profile projection of a selected vertical frame profile; and
wherein the push-on seal is substantially H-shaped in cross-section, and between the opposing legs of the push-on seal a gap is formed, which widens starting from a bridge that connects the legs.

10. The cabinet system of claim 9 further comprising:
a connecting bridge connecting the two profile projections, the profile projections extending at an angle of substantially 135° in relation to the bridge.

11. The switchgear cabinet system according to claim 9 , wherein each of the profile projections extends perpendicularly from a respective profile side.

12. The switchgear cabinet system according to claim 9 , wherein between the two hollow chambers, bordering the connecting bridge, a dovetail groove is formed, which is symmetrical with respect to the cross-sectional diagonal.

13. The switchgear cabinet system according to claim 9 , wherein between the two hollow chambers, bordering the connecting bridge, a third hollow chamber is formed.

14. The switchgear cabinet system according to claim 9 wherein the frame profile comprises two profile projections that extend perpendicularly to each other.

15. The switchgear cabinet system according to claim 9 wherein at least one of the profile projections is formed by a portion that is folded back onto itself.
