Abstract

A method for producing a triple insulating glazing unit is presented. According to the method, one pane is inserted into a groove of a spacer that is peripherally shaped to form a spacer frame to enframe the pane. A first pane and a second pane are connected to corresponding contact surfaces of the spacer frame by way of an upper edge and lateral edges of the first and second panes. Lower edges of the first and second panes are bent outward. Formed interpane spaces are filled from below with a protective gas, and the arrangement of the panes and the spacer frame is sealed and pressed together.

First claim

The invention claimed is:

1. A method for producing a triple insulating glazing unit, the method comprising:
a) inserting a pane into a groove of a spacer that is peripherally shaped to form a spacer frame, the spacer frame enframing the pane, wherein the spacer frame with the pane are arranged between a first pane and a second pane,
b) connecting the first pane to a first pane contact surface of the spacer frame and connecting the second pane to a second pane contact surface of the spacer frame via a respective upper edge and respective lateral edges of the first pane and the second pane, and bending outward a respective lower edge of the first pane and of the second pane,
c) filling, from below, interpane spaces with protective gas, and
d) sealing and pressing together, a pane arrangement comprising the pane, the spacer frame, the first pane, and the second pane.

2. The method for producing a triple insulating glazing unit according to claim 1 ,
wherein step b), in which the respective lower edge of the first pane and of the second pane is bent outward, and step c), in which the interpane spaces are filled, from below, with protective gas, occur simultaneously.

3. The method for producing a triple insulating glazing unit according to claim 1 ,
wherein
first, the respective lower edge of the first pane and of the second pane is bent outward, and
second, an arrangement comprising the spacer frame and the enframed pane is arranged between the first pane and the second pane.

4. The method for producing a triple insulating glazing unit according to claim 1 , wherein the respective lower edge is bent outward 2 mm to 10 mm.

5. The method for producing a triple insulating glazing unit according to claim 1 , wherein the respective lower edge is bent outward 4 mm to 6 mm.

6. The method for producing a triple insulating glazing unit according to claim 1 , wherein the respective lower edge is bent outward with a suction device.

7. The method for producing a triple insulating glazing unit according to claim 1 , wherein the interpane spaces are filled with protective gas, from below, through a gap formed by the bending outward of the respective lower edge of the first pane and of the second pane.

8. The method for producing a triple insulating glazing unit according to claim 1 , wherein the interpane spaces are filled, from below, with noble gas.

9. The method for producing a triple insulating glazing unit according to claim 8 , wherein the noble gas comprises one of: a) argon, b) krypton, and c) mixtures of a) and b).

10. The method for producing a triple insulating glazing unit according to claim 1 , wherein after the sealing, and pressing together, of the pane arrangement, an outer insulation is filled peripherally in an outer region of the pane arrangement between an outer surface of the spacer frame and outer edges of the first and second panes.

11. A device configured to carry out the method for producing a triple insulating glazing unit according to claim 1 , the device comprising:
a) a rack into which the spacer frame with the enframed pane, and the first pane and the second pane are inserted,
b) a suction device configured to bend outward the respective lower edge of the first pane and of the second pane,
c) a gas filling device configured to fill the interpane spaces with the protective gas from below through gaps formed by bending outward of the respective lower edge of the first pane and of the second pane, and
d) a pressing device configured to press together the pane arrangement by peripherally pressing edges of the first pane and of the second pane respectively against a first pane contact surface and a second pane contact surface of the spacer frame.

12. The device according to claim 11 , wherein the suction device has at least two suction cups.

13. A triple insulating glazing unit comprising:
a spacer that is peripherally shaped to form a spacer frame,
a pane, enframed by the spacer frame, wherein the pane is inserted into a groove of the spacer,
a first pane attached on a first pane contact surface of the spacer frame, and
a second pane attached on a second pane contact surface of the spacer frame,
wherein interpane spaces formed by the enframed pane, the first pane, and the second pane, are filled, from below, with a protective gas,
wherein a pane arrangement comprising the enframed pane, the spacer frame, the first pane, and the second pane, is sealed and pressed together, and
wherein an outer region of the pane arrangement between an outer surface of the spacer frame and outer edges of the first and second panes contains outer insulation filled peripherally and separated from the outer surface of the spacer via an insulating film applied to the outer surface.
