  "claims": [
    "1. A method for attaching a first window component to a second window component comprising the steps of: a) engraving a surface of the first window component with at least one cavity by subjecting the first window component to a laser beam at a polar angle, α1; and b) attaching the second window component to the first window component by introducing an anchor portion into the at least one cavity, said anchor portion being an adhesive provided in a layer between the engraved surface of the first window component and the second window component. 2. The method according to claim 1, wherein the at least one cavity is engraved at a polar angle, α1, different from 0 degrees, preferably between 10 and 80 degrees, more preferably between 15 and 70 degrees, most preferably between 20 and 60 degrees. 3. The method according to claim 1, wherein step a) further comprises engraving the surface with at least one further cavity by subjecting the first window component 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 surface of the first window component 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 and/or at least one further cavity form a pattern in the surface of the first window component, the pattern is one of a mesh, grid, circle and a spiral. 6. The method according to claim 1, wherein the first component is made from glass, metal or plastic. 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 surface of the first window component. 8. A method for attaching a first window component to a second window component comprising the steps of: a) engraving a surface of the first window component with at least one cavity by subjecting the first window component to a laser beam at a polar angle, α1; and b) attaching the second window component to the first window component by introducing an anchor portion of the second window component into the least one cavity, wherein the anchor portion is a thermoplastic polymer, and introducing the anchor portion into the at least one cavity of the engraved surface is performed by melting the anchor portion of the second component and allowing the melted anchor portion to settle into the at least one cavity of the engraved surface of the first window component. 9. The method according to claim 8, wherein the melting of the anchor portion of the second component is accomplished by laser, heat, or ultra-sound. 10. A method for attaching a first window component to a second window component comprising the steps of: a) engraving a surface of the first window component with at least one cavity by subjecting the first window component to a laser beam at a polar angle, α1; and, b) moulding the second window component directly on the engraved surface, whereby an anchor portion of the second window component is introduced into and formed in the at least one cavity of the engraved surface of the first window component. 11. The method according to claim 10, wherein the moulding of the second window component on the first window component is performed by injection moulding. 12. (canceled) 13. The method according to claim 1, wherein the surface of the second window component facing the adhesive layer is subjected to step a. 14. The method according to claim 13, wherein the adhesive is light-curable adhesive. 15. The method according to claim 1, wherein the method comprises an additional step of pressing the first window component and the second window component against each other during and/or subsequently after step b)."

  "description_excerpt": "The present invention relates to a method for attaching window components, particularly roof window components.\n\nThe attachment of window components in particular attachments of window components made from different materials, such as plastics and metals, have traditionally been obtained by mechanical fasteners such as screws, nails or rivets. The use of mechanical fasteners for attaching two window components is advantageous, because such attachments are able to withstand relatively large forces such as pulling, pushing, and tugging from a user, but also environmental induced stress such as changing weather conditions and wind causing vibrations in the window installation. In the context of the application, window components should be understood as components having a well defined structure for an application in a building window, such as a roof window. Window components include but are not limited to claddings, covers, frame, sash, window pane, top box, hinges, hinge connections, locks, locking mechanisms, fittings, etc. A drawback of using mechanical fasteners is that the fasteners are often visible and thereby reduces the overall aesthetic perception of the user of the window.\n\nAdditionally, fasteners often deform the component which they penetrate, either during the manufacturing or installation processes or in use. Hence, mechanical properties of the window component may be compromised. Furthermore, the fasteners induce an additional way for water to enter the interior of the window which can cause problems with rust and corrosion.",
