Window element for inserting in a structural part and method of integration of a window element in a structural part

1. A window element masked for painting, comprising:

a window frame connectable to a window cutout in a structural part;

a retainer;

a window assembly, having an inner pane, an outer pane, and an encircling sealing profile, positionable between the retainer and the window frame;

fastening elements structured and arranged to clamp the window assembly on the window frame;

the sealing profile having an outer inclined surface and the window frame having an inner inclined surface abutting the outer inclined surface, such that the outer inclined surface and the inner inclined surface are arranged to self-center the window assembly in the window frame;

a covering layer structured and arranged to at least partly cover the outer pane; and

an encircling covering tape comprising a first section that covers a border area of the covering layer and a second section that is at least sectionally positioned between the outer inclined surface of the seal profile and the inner inclined surface of the window frame.

2. The window element according to claim 1 , wherein the outer inclined surface of the seal profile has a concave surface and the inner inclined surface of the window frame has a convex surface.

3. The window element according to claim 2 , wherein the outer inclined surface of the seal profile and the inner inclined surface of the window frame have an ellipsoid form in cross-sections of the seal profile of the window frame.

4. The window element according to claim 1 , further comprising an encircling recess structured and arranged to self-center the window, wherein the encircling recess is formed in the outer inclined surface of the seal profile and the inner inclined surface of the window frame.

5. The window element according to claim 1 , wherein the retainer is structured and arranged to clamp the window assembly on the window frame via the fastening elements.

6. The window element according to claim 1 , wherein the window frame has one of an L-shaped or T-shaped cross-sectional geometry.

7. The window element according to claim 1 , wherein the cross-section of the window frame has an inwardly extending section on an inner end thereof.

8. The window element according to claim 1 , wherein the covering layer is placed on the outer pane so that a border area of the surface of the outer pane is left free.

9. The window element according to claim 8 , wherein the covering layer and the covering tape overlap each other at least in some regions in the border area of the surface of the outer pane.

10. The window element according to claim 1 , wherein the covering layer is structured and arranged to completely cover the outer pane.

11. The window element according to claim 1 , wherein the covering tape has a high shearing strength to allow it to be pulled out without leaving a residue.

12. The window element according to claim 1 , wherein the covering layer is a self-adhesive plastic film that is detachable without leaving a residue.

13. The window element according to claim 1 , wherein the covering tape is a self-adhesive plastic tape that is detachable without leaving a residue.

14. The window element according to claim 1 , wherein the covering tape and the covering layer are formed by a thermoplastic material.

15. A method of integrating the window element according to claim 1 in a structural part, comprising:

inserting the window element in an opening of a structural part;

painting at least a part of the structural part; and

removing the covering tape and the covering layer.

16. The method according to claim 15 , wherein the covering layer is removed prior to removing the covering tape.

17. The method according to claim 15 , wherein the covering tape is removed prior to removing the covering layer.
