SECTIONAL DOOR

Abstract

Embodiments of the present invention provide a sectional door with a door leaf movable longitudinally along a preset path between a closed and an open position, with said door leaf having a shell-like or single-wall design, with a shell bottom forming an outer boundary surface of the door leaf, and two shell edges preferably extending over the entire door leaf width in the direction of the articulating axes and protruding from the shell bottom in the direction of the space closed off thereby, with one of the shell edges having a hollow protrusion extending over the entire width of the door leaf and the other shell edge comprising a recess designed to accommodate a protrusion of an adjacent door leaf element, and with an insulating element, being inserted into the shell-like door leaf element, with the insulating element having a flange capable of being inserted into the hollow protrusion of the door leaf element and/or an edge profile on or in an edge of an insulating element, with said edge profile being designed to accommodate at least a part of the recess of the door leaf element which extends in the thickness direction of the door leaf element.

Claims

1. A sectional door leaf, comprising: a single-wall shell, said single-wall shell comprising a shell bottom forming an outer surface of the door leaf and two shell edges protruding from the shell bottom, a first of said two shell edges having a hollow protrusion, and the second of said two shell edges having a recess designed to accommodate a protrusion of an adjacent door leaf; andan insulating element inserted into the single-wall shell, wherein said insulating element comprises at least one element for cooperation with said hollow protrusion, said recess, or both.

2. The sectional door leaf of claim 1, wherein said single-wall shell design comprises a cold-formed metal shell.

3. The sectional door leaf of claim 1, wherein said two shell edges extend along the entire width of the door leaf.

4. The sectional door leaf of claim 1, wherein said two shell edges extend in the direction of a space to be closed off by the door leaf.

5. The sectional door leaf of claim 1, wherein said hollow protrusion of said first of said two shell edges extends along the entire width of the door leaf.

6. The sectional door leaf of claim 1, wherein said hollow protrusion of said first of said two shell edges extends partially upwards when said door leaf is in a closed position.

7. The sectional door leaf of claim 1, wherein said insulating element comprises an insulating board made of polystyrene.

8. The sectional door leaf of claim 1, wherein said insulating element is removable.

9. The sectional door leaf of claim 1, wherein said at least one element for cooperation with said hollow protrusion, said recess, or both comprises a flange for insertion into and cooperation with said hollow protrusion of said first of said two shell edges.

10. The sectional door leaf of claim 9, wherein said flange extends along the entire width of the insulating element.

11. The sectional door leaf of claim 1, wherein said insulating element further comprises an edge having an edge profile and wherein said at least one element for cooperation with said hollow protrusion, said recess, or both comprises said edge profile, said edge profile being designed to accommodate at least one portion of the recess of the second of said two shell edges.

12. The sectional door leaf of claim 1, wherein said shell bottom has a cassette or beaded profile extending at least partially in the direction of a space to closed off by the door leaf.

13. The sectional door leaf of claim 12, wherein said insulating element has a surface facing the shell bottom and further comprising an insulating element recess in the surface facing the shell bottom, said insulating element recess designed to accommodate said cassette or beaded profile of the shell bottom.

14. The sectional door leaf of claim 13, wherein said insulating element recess extends along the entire width of the insulating element.

15. The sectional door leaf of claim 1, wherein said insulating element has a weak area facilitating bending around a bending axis extending parallel to the width of the insulating element.

16. The sectional door leaf of claim 15, wherein said insulating element has a surface facing the shell bottom and wherein said weak area comprises at least one slot in the surface facing the shell bottom.

17. The sectional door leaf of claim 16, wherein said at least one slot extends into a portion of the thickness of the insulating element in a direction approximately perpendicular to the width of the insulating element.

18. The sectional door leaf of claim 16, wherein said at least one slot comprises a plurality of slots.

19. The sectional door leaf of claim 15, wherein said insulating element has a surface facing the shell bottom and further comprising an insulating element recess in the surface facing the shell bottom, and wherein the weak area is located in the insulating element recess.

20. The sectional door leaf of claim 1, wherein said sectional door leaf is one of a plurality of sectional door leaf elements that are coupled together.

21. An insulating element for use in cooperation with a sectional door leaf having a single-wall shell, said insulating element comprising: an upper flange for insertion into and cooperation with a hollow protrusion of a first edge of the single-wall shell; anda lower edge having an edge profile designed to accommodate at least one portion of a recess of a second edge of the single-wall shell.

22. The insulating element of claim 21, wherein said insulating element comprises an insulating board made of polystyrene.

23. The insulating element of claim 21, wherein said upper flange extends along the entire width of the insulating element.

24. The insulating element of claim 21, further comprising an insulating element recess, wherein when said insulating element is in use, said insulating element recess faces the single-wall shell and wherein said insulating element recess is designed to accommodate a profile of the single-wall shell.

25. The insulating element of claim 24, wherein said insulating element recess extends along the entire width of the insulating element.

26. The insulating element of claim 21, further comprising a weak area facilitating bending around a bending axis extending parallel to the width of the insulating element.
