Abstract

An adapter element for connecting a pane to a spacer having a fastening groove, wherein the adapter element includes at least one receiving profile for securing to the pane and at least one lower part for fixing to the spacer, and the lower part is designed to positively fit the fastening groove of the spacer.

First claim

The invention claimed is:

1. Adapter element for connecting a pane to a spacer having a fastening groove, wherein the adapter element comprises at least one receiving profile for securing to the pane and at least one lower part for fixing to the spacer, and the lower part is positively connected to the fastening groove of the spacer,
wherein the at least one receiving profile is U-shaped and/or two opposite side legs of the at least one receiving profile are step-shaped.

2. The adapter element according to claim 1 , wherein the at least one lower part of the adapter element is trapezoidal.

3. The adapter element according to claim 1 , wherein the adapter element is formed in one piece.

4. The adapter element according to claim 1 , wherein the adapter element contains polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene/polycarbonate (ABS/PC), styrene acrylonitrile (SAN), PET/PC, PBT/PC, and/or copolymers or mixtures thereof.

5. Spacer with a main body comprising a first pane contact surface and a second pane contact surface extending parallel thereto, a first glazing interior surface, a second glazing interior surface, an outer surface, a first hollow chamber and a second hollow chamber, a fastening groove extending parallel to the first pane contact surface and second pane contact surface between the first glazing interior surface and the second glazing interior surface in a longitudinal direction of the spacer, wherein
the first hollow chamber is adjacent the first glazing interior surface, and the second hollow chamber is adjacent the second glazing interior surface,
side flanks of the fastening groove are formed by the walls of the first hollow chamber and the second hollow chamber, and
wherein the fastening groove has an adapter element according to claim 1 .

6. The spacer according to claim 5 , wherein the fastening groove is trapezoidal.

7. Insulating glazing at least comprising a first pane, a second pane, a third pane, and a spacer according to claim 5 , an outer interpane space between the first pane, the second pane, and the outer surface of the spacer, a first inner interpane space between the first pane, the third pane, and a first glazing interior surface of the spacer, and a second inner interpane space between the second pane, the third pane, and a second glazing interior surface of the spacer, wherein
the first pane is bonded to the first pane contact surface via a seal,
the second pane is bonded to the second pane contact surface via a seal,
the third pane is formed by at least one thermoplastic polymer pane, and
an edge region of the third pane is arranged in the at least one receiving profile of the adapter element.

8. The insulating glazing according to claim 7 , wherein the at least one receiving profile brackets a circumferential edge in the edge region of the third pane.

9. The insulating glazing according to claim 7 , wherein the thermoplastic polymer pane has a thickness of at least 3 mm.

10. The insulating glazing according to claim 7 wherein the third pane comprises a plurality of panes and includes at least one thermoplastic polymer pane.

11. The insulating glazing according to claim 10 , wherein the plurality of panes are bonded via laminating films to form the third pane.

12. The insulating glazing according to claim 7 , wherein the circumferential edge of the third pane does not directly contact the bottom surface of the receiving profile.

13. Method for producing an insulating glazing according to claim 7 , comprising
a) inserting the adapter element into a fastening groove of a spacer,
b) inserting the third pane into the receiving profile of the adapter element,
c) bonding the first pane to the first pane contact surface of the spacer via a seal and bonding the second pane to the second pane contact surface of the spacer via a seal,
d) pressing together the pane assembly comprising the first, second, and third pane and the spacer, and
e) sealing the entire insulating glazing unit.

14. A method comprising utilizing an insulating glazing according to claim 7 as a breakthrough-resistant glazing in the building exterior, and/or in façades.

15. The method according to claim 14 , wherein the insulating glazing is arranged in a building interior.
