Abstract

A method of providing a covering element with a connection element for covering a hinge part of a roof window comprising the steps of engraving an interior surface of the covering element to provide an engraved surface with at least one cavity by subjecting the covering element to a laser beam at a polar angle, α1, and attaching the connection element to the covering element by introducing an anchor portion of the connection element into the least one cavity.

First claim

The invention claimed is:

1. A method of providing a covering element with a connection element for covering a hinge part of a roof window comprising the steps of:
a) engraving an interior surface of the covering element to provide an engraved surface with at least one cavity by subjecting the covering element to a laser beam at a polar angle, α1; and
b) attaching the connection element to the covering element by introducing an anchor portion into the least one cavity, wherein the anchor portion forms a part of the connection element or is operably connected to the connection element.

2. The method according to claim 1 , wherein the at least one cavity is engraved at a polar angle, α1, different from 0 degrees.

3. The method according to claim 1 , wherein step a) further comprises engraving the engraved surface with at least one further cavity by subjecting the covering element to a laser beam from a different direction than that used to engrave the at least one cavity, such that the at least one cavity and the at least one further cavity do not extend into the engraved surface in parallel directions.

4. The method according to claim 3 , wherein the at least one cavity and the at least one further cavity are engraved at the same polar angle, α1, but at different azimuth angles.

5. The method according to claim 1 , wherein the at least one cavity forms a pattern in the interior surface of the covering element, the pattern being one of a mesh, a grid, a circle and a spiral.

6. The method according to claim 1 wherein the covering element is made from plastic or metal.

7. The method according to claim 1 , wherein the laser engraving is performed by at least two lasers, wherein the at least two lasers provide a laser beam from different polar and/or azimuth angles on the engraved surface of the covering element.

8. The method according to claim 1 , wherein the anchor portion is a thermoplastic polymer, and the step of introducing the anchor portion into the engraved surface in step b is performed by melting the anchor portion and allowing the melted anchor portion to settle into the at least one cavity of the engraved surface, wherein the anchor portion forms a part of the connection element.

9. The method according to claim 8 , wherein the melting of the anchor portion is accomplished by laser, heat, or ultra-sound.

10. The method according to claim 1 , wherein the connection element is molded directly on the engraved surface, whereby the anchor portion is introduced into and formed in the engraved surface.

11. The method according to claim 10 , wherein the molding of the connection element to the covering element is performed by injection molding.

12. The method according to claim 1 , wherein the anchor portion is an adhesive provided in a layer between the engraved surface of the covering element and the connection element.

13. The method according to claim 12 , wherein the engraved surface of the covering element facing the adhesive layer is subjected to step a.

14. The method according to claim 12 , wherein the adhesive is a light-curable adhesive.

15. The method according to claim 12 , wherein the adhesive is a UV-curable adhesive.

16. The method according to claim 1 , wherein the method comprises an additional step of pressing the covering element and the connection element against each other during and/or subsequently after step b).

17. The method according to claim 1 , wherein step a) further comprises engraving the engraved surface with at least one further cavity and the at least one cavity and/or the at least one further cavity form a pattern in the interior surface of the covering element, the pattern being one of a mesh, a grid, a circle and a spiral.

18. The method according to claim 1 , wherein step a) further comprises engraving the engraved surface with at least one further cavity and the at least one cavity and the at least one further cavity form a pattern in the interior surface of the covering element, the pattern being one of a mesh, a grid, a circle and a spiral.

19. The method according to claim 1 , wherein the method comprises an additional step of pressing the covering element and the connection element against each other during and subsequently after step b).

20. The method according to claim 1 , wherein the method comprises an additional step of pressing the covering element and the connection element against each other during step b).
