Abstract

The present disclosure relates to an aperture cover (1) such as a window. The aperture cover comprises a vacuum insulated glass unit (3) and a frame (2). The frame (2) comprises a fixation frame (7) and a sash (6) fixed to the vacuum insulated glass unit (3), and wherein the sash (6) is movably connected to the fixation frame (7) by means of a hinge connection (80). The fixation frame (7) comprises elongated frame members (8a-8d) defining a frame opening (2a) and the vacuum insulated unit (3) overlaps a surface (11) of at least one elongated frame member (8a-8d) of the fixation frame (7). The sash (6) comprises a sash profile (13) which is fixed to the vacuum insulated glass unit (3) at a part (21, 22) of the vacuum insulated glass unit that overlaps (21) and/or extends beyond (22) the overlapped elongated frame member (8a-8d). A resilient sealing gasket (10) is arranged between the overlapped elongated frame member (8a-8d) and the vacuum insulated glass unit, and the resilient sealing gasket (10) is configured to abut the interior major surface (S2) of the vacuum insulated glass unit when the sash (6) is in a closed position. The interior major surface (S2) of the vacuum insulated glass unit is configured to compress the resilient sealing gasket (10) when moving the sash (6) from an open to a closed position.

First claim

The invention claimed is:

1. An aperture cover, wherein the aperture cover comprises:
a vacuum insulated glass unit comprising a first glass sheet and a second glass sheet, wherein an evacuated gap is placed between the first and second glass sheets, wherein a plurality of support structures are distributed in the evacuated gap, wherein an edge seal encloses the evacuated gap, wherein the edge seal comprises a rigid, fused edge seal, wherein the vacuum insulated glass unit comprises outer major surfaces, and
a frame, wherein the frame comprises a fixation frame and a sash which is fixed to the vacuum insulated glass unit, and wherein the sash is movably connected to the fixation frame by means of a hinge connection,
wherein the fixation frame comprises elongated frame members defining a frame opening, wherein the vacuum insulated unit is configured to overlap a surface of at least one elongated frame member of the fixation frame, at least when the sash is in a closed position, and wherein the sash comprises a sash profile which is fixed to the vacuum insulated glass unit at a part of the vacuum insulated glass unit that overlaps and/or extends beyond the overlapped elongated frame member,
wherein a resilient sealing gasket is arranged between the overlapped elongated frame member and the vacuum insulated glass unit, wherein the resilient sealing gasket is configured to abut an interior major surface of the vacuum insulated glass unit when the sash is in a closed position, and wherein the interior major surface of the vacuum insulated glass unit is configured to compress the resilient sealing gasket when moving the sash from an open to a closed position,
wherein the sash profile is elongated and attached to the interior major surface of the vacuum insulated glass unit by means of a bonding seal;
wherein a resilient sealing is placed between a protection wall and an edge surface of the vacuum insulated glass unit.

2. An aperture cover according to claim 1 , wherein the sealing gasket is configured to be compressed by at least 2 mm by the interior major surface of the vacuum insulated glass unit when compared to a sealing gasket height in an uncompressed condition, when a temperature difference between the glass sheets of the vacuum insulated glass unit is substantially 0° C.

3. An aperture cover according to claim 1 , wherein a height of the resilient sealing gasket is configured to be at least 5 mm in an uncompressed/un-deflected condition.

4. An aperture cover according to claim 3 , wherein the height of the resilient sealing gasket is at least 8 mm or at least 10 mm in an uncompressed condition.

5. An aperture cover according to claim 1 , wherein a magnitude of a compression of the sealing gasket by the vacuum insulated glass unit is configured to vary across a length of the sealing gasket when a temperature difference between the two glass sheets of the vacuum insulated glass unit enclosing the evacuated gap is 65° C.

6. An aperture cover according to claim 1 , wherein the sealing gasket is placed with a distance of at least 25 mm from an edge of the vacuum insulated glass unit when the sash is in a closed position.

7. An aperture cover according to claim 1 , wherein the sash profile is a as-metal profile, wherein the bonding seal comprises a structural adhesive, wherein said bonding seal has a thickness between 4 mm and 13 mm at a temperature difference between the two glass sheets of the vacuum insulated glass unit of substantially 0° C.

8. An aperture cover according to claim 1 , wherein the exterior major surface of the vacuum insulated glass unit is substantially uncovered by the sash.

9. An aperture cover according to claim 1 , wherein the aperture cover is a roof window.

10. An aperture cover according to claim 1 , wherein the elongated frame members of the fixation frame comprises a top profile member, a bottom profile member and two parallel side profile members, and wherein the overlapped elongated frame member is at least the two parallel side profile members and/or the bottom profile member.

11. An aperture cover according to claim 1 , wherein an edge of the vacuum insulated glass unit extending parallel to and along the overlapped elongated frame member is allowed to deflect in response to a temperature difference between the two glass sheets of the vacuum insulated glass unit.

12. An aperture cover according to claim 11 , wherein one or more of the edges of the vacuum insulated glass unit is/are allowed to provide a deflection curve/arc between corners where the respective edge terminates in response to a temperature difference between the two glass sheets of the vacuum insulated glass unit.

13. An aperture cover according to claim 1 , wherein the sash profile is fixed to the vacuum insulated glass unit at a part of the vacuum insulated glass unit that overlaps the overlapped elongated frame member.

14. An aperture cover according to claim 1 , wherein the vacuum insulated glass unit overlaps the fixation frame by a distance, wherein said distance is at least 2.5 cm.

15. An aperture cover according to claim 1 , wherein a part of the vacuum insulated glass unit extends beyond an outer surface of the fixation frame with a distance of at least 1 cm.

16. An aperture cover according to claim 1 , wherein the sash profile is fixed to the vacuum insulated glass unit at a part of the vacuum insulated glass unit that extends beyond an outermost surface of the fixation frame.

17. An aperture cover according to claim 1 , wherein the vacuum insulated glass unit is a laminated vacuum insulated glass unit comprising a lamination interlayer bonding a lamination glass sheet to a major surface of the vacuum insulated glass unit, wherein the lamination glass sheet is arranged at a side facing the overlapped elongated frame member, wherein the lamination glass sheet comprises the interior major surface of the vacuum insulated glass unit which the resilient sealing gasket is configured to abut when the sash is in a closed position.

18. An aperture cover according to claim 1 , wherein a minimum distance between an outer major surface of the vacuum insulated glass unit and walls of said frame is at least 4 mm at a temperature difference between the two glass sheets of the vacuum insulated glass unit of substantially 0° C.

19. An aperture cover according to claim 1 , wherein the a largest total edge deflection in a deflection direction of any of the edges of the vacuum insulated glass unit at a temperature difference between the two glass sheets of 65° C. as compared to the vacuum insulated glass unit at a temperature difference of 0° C. is at least 0.3% of a length of the deflecting edge.
