Abstract

The disclosure describes a frame profile for a frame rack of a service cabinet, consisting of an outer profile part manufactured from a first material, wherein the outer profile part forms at least a first wall of the frame profile which partially limits a hollow chamber; and of an inner profile part manufactured from a second material which differs from the first material by at least one quality, wherein the inner profile part forms at least one other wall of the hollow chamber.

First claim

The invention claimed is:

1. A frame profile for a frame rack of a service cabinet comprising:
an outer profile part manufactured from a first material, wherein the outer profile part forms a first wall of the frame profile which partially limits a hollow chamber; and
an inner profile part manufactured from a second material which differs from the first material by at least one quality, wherein the inner profile part forms at least one other wall of the hollow chamber;
wherein the hollow chamber is constructed to be continuous over the length of the frame profile and that the inner profile part is folded in order to form two profile attachments which are provided with perforations and which extend at an angle of 90° with respect to one another;
wherein the inner profile part forms three other walls of the hollow chamber;
wherein the first wall of the outer profile part and the three other walls form the hollow chamber which is rectangular or quadric in cross-section; and
wherein the two profile attachments which are provided with perforations are folded to comprise a double wall thickness compared to the three other walls.

2. The frame profile according to claim 1 , wherein the thickness of the outer profile part differs from the thickness of the inner profile part.

3. The frame profile according to claim 1 , wherein the hollow chamber is reinforced with a hard foam.

4. The frame profile according to claim 1 , wherein the hollow chamber is reinforced with a soft foam.

5. The frame profile according to claim 4 , wherein the hollow chamber is filled with the soft foam with open pores.

6. The frame profile according to claim 3 , wherein the hard foam is a foam based on polyester or polyurethane.

7. The frame profile according to claim 1 , wherein the hollow chamber is filled with an inorganic material including metallic foam or concrete.

8. The frame profile according to claim 1 , wherein the outer profile part and the inner profile part are connected together to at least one profile attachment which extends away from the hollow chamber.

9. The frame profile according to claim 1 , wherein the hollow chamber is rectangular, quadratic, trapezoidal or like a rhombus in cross section.

10. The frame profile according to claim 8 , wherein the profile attachment or the profile attachments is/are constructed on edges of the hollow chamber.

11. The frame profile according to claim 1 , wherein the two profile attachments that are orientated at an angle of 135° with respect to the three other walls of the hollow chamber.

12. The frame rack for a service cabinet in which a frame profile according to claim 1 is constructed at least as a vertical profile.

13. The frame profile according to claim 4 , wherein the soft foam is a foam based on polyester or polyurethane.

14. The frame profile according to claim 5 , wherein the soft foam is a foam based on polyester or polyurethane.

15. The frame profile of claim 1 , wherein the inner profile part forms two profile attachments that extend perpendicular to each other, each one of the two profile attachments is provided with perforations.

16. A frame profile for a frame rack of a service cabinet comprising:
a first profile part manufactured from a first material, the first profile part forms a first wall of the frame profile that partially defines a hollow chamber;
a second profile part manufactured from a second material that is different from the first material;
the first and second profile parts connected together to form the hollow chamber having two wing sections extending outwardly therefrom, the first profile part defining a first region of side walls for the chamber, and the second profile part defining a different second region of side walls for the chamber;
the two wing sections being formed from folded sections of the second profile part;
the two wing sections having perforations therein;
the two wing sections extend at 90° angles with respect to one another;
the second profile part forms three other walls of the hollow chamber;
wherein the first wall of the first profile part and the three other walls of the second profile part define the hollow chamber, which is rectangular or quadric in cross-section; and
wherein the two wing sections, which are provided with the perforations, are folded to provide each one of the two wing sections with a wall thickness that is twice as great as wall thicknesses of each of the three other walls.

17. The frame profile of claim 1 , wherein the perforations in the two profile attachments are the only perforations of the frame profile.

18. The frame profile of claim 17 , wherein a first and a second sheet metal layer of each of the two profile attachments abut against each other over the entire length and width of the respective profile attachment.
