Abstract

The present disclosure relates to a vacuum insulated glass (VIG) unit frame assembly ( 10 ), wherein said vacuum insulated glass unit frame assembly ( 1 ) comprises: a vacuum insulated glass unit ( 1 ), and a frame ( 20 ) comprising elongated frame profile arrangements ( 20 a - 20 d, 70 ) which frames said vacuum insulated glass unit ( 1 ) in a frame opening ( 21 ). The frame further comprises: —holding parts ( 6 ) for fixating said vacuum insulated glass unit ( 1 ), and—flexible connection arrangements ( 7 ) connecting the holding parts ( 6 ) to elongated frame profile arrangements ( 20 a - 20 d ). The flexible connection arrangements ( 7 ) are configured to flex when said vacuum insulated glass unit ( 1 ) exerts a bending moment (M) on the holding parts ( 6 ), so that said holding parts ( 6 ) will move relative to the elongated frame profile arrangements ( 20 a - 20 d, 70 ) to which the individual holding part ( 6 ) is connected. The present disclosure moreover relates to a vacuum insulated glass unit and a frame.

First claim

The invention claimed is:

1. A vacuum insulated glass unit frame assembly, wherein said vacuum insulated glass unit frame assembly comprises:
a rectangular vacuum insulated glass unit comprising at least two glass sheets separated by a gap between said glass sheets, wherein a plurality of support structures are distributed in said gap and wherein said gap is sealed, and
a frame comprising elongated frame profile arrangements which frames said vacuum insulated glass unit in a frame opening, the frame further comprising:
holding parts for fixating said vacuum insulated glass unit, and
flexible connection arrangements connecting the holding parts to elongated frame profile arrangements,

wherein said flexible connection arrangements are configured to flex when said vacuum insulated glass unit exerts a bending moment on the holding parts, so that said holding parts will move relative to the elongated frame profile arrangements to which the individual holding part is connected;
wherein the largest total edge deflection of any of the edges of the vacuum insulated glass unit, at a temperature difference (ΔT=T 1 − 72 ) between the two glass sheets of 65° C. as compared to the vacuum insulated glass unit at a temperature difference (ΔT=T 1 −T 2 ) of 0° C. is at least 2 mm.

2. The vacuum insulated glass unit frame assembly according to claim 1 , wherein said holding parts each comprise a recessed portion provided between holding members arranged at opposite outwardly facing surfaces of the vacuum insulated glass unit, and wherein an edge of the vacuum insulated glass unit extends into the recessed portion and is held in said recess by means of the holding members.

3. The vacuum insulated glass unit frame assembly according to claim 2 , wherein said flexible connection arrangement is configured to allow a rotational and/or linear movement of the holding parts relative to the elongated frame profile arrangements to which the individual holding part is connected, in response to a thermal deflection of the edges of the vacuum insulated glass unit extending into the recessed portion of the respective holding part.

4. The vacuum insulated glass unit frame assembly according to claim 2 , wherein an interconnecting wall part of the holding part interconnects said holding members and provides a bottom wall member of the recess receiving the vacuum insulated glass unit edge.

5. The vacuum insulated glass unit frame assembly according to claim 2 , wherein said vacuum insulated glass unit is fixed between said holding members by means of fixation arrangements arranged between the respective holding member and an outwardly facing surface of the vacuum insulated glass unit, wherein said fixation arrangements comprises one or more suspension elements compressed between a first of said holding members and one of said opposite outwardly facing surfaces, and one or more resilient suspension elements compressed between a second of said holding members and the other of said opposite outwardly facing surfaces, wherein said compressed, resilient suspension elements provides a holding force towards said opposite outwardly facing surfaces of the vacuum insulated glass unit so as to suspend the vacuum insulated glass unit between said first and second holding members, and wherein each of said compressed, resilient suspension elements are configured to be further compressed or expand in response to said thermal deflection of the edge of the vacuum insulated glass unit due to a temperature difference (ΔT=T 1 −T 2 ) between the two glass sheets.

6. The vacuum insulated glass unit frame assembly according to claim 1 , wherein said flexible connection arrangements comprises one or more wall members configured to provide said flexing and wherein a wall member of said one or more wall members of the flexible connection arrangement is configured to provide or support one of said holding members of the holding part.

7. The vacuum insulated glass unit frame assembly according to claim 1 , wherein a flexing space is provided between an outwardly facing major surface of the vacuum insulated glass unit and said elongated frame profile arrangements to which the individual holding part is connected, wherein one or more distancing walls of the flexible connection arrangement provides said flexing space, and wherein said vacuum insulated glass unit is configured to flex towards and away from said flexing space in response to said bending moment.

8. The vacuum insulated glass unit frame assembly according to claim 7 , wherein the minimum distance between an outer surface of the elongated frame profile arrangement facing the flexing space, and a surface of a holding member of the holding part proximate to and facing the flexing space is at least 0.4 cm when the temperature difference (ΔT=T 1 −T 2 ) of the glass sheets ( 2 a , 2 b ) of the vacuum insulated glass unit is 0° C.

9. The vacuum insulated glass unit frame assembly according to claim 7 , wherein a separation wall arrangement is arranged between said flexing space and the frame opening.

10. The vacuum insulated glass unit frame assembly according to claim 1 , wherein said flexible connection arrangements comprises a wall member extending from said holding member, wherein the wall member comprises one or more bends towards and/or away from a plane, wherein said plane extends substantially perpendicularly to said frame opening and is substantially parallel to the respective edge of the vacuum insulated glass unit held by the holding part.

11. The vacuum insulated glass unit frame assembly according to claim 1 , wherein an elongated tightening gaskets or sealing is/are arranged between said frame opening and the flexible connection arrangement, and wherein said elongated tightening gaskets or sealing provides a tightening between a major surface of the vacuum insulated glass unit and said frame.

12. The vacuum insulated glass unit frame assembly according to claim 1 , wherein said flexible connection arrangements and holding parts are integrated in the same frame profile which is an extruded, moulded and/or pultruded profile.

13. The vacuum insulated glass unit frame assembly according to claim 1 , wherein said flexible connection arrangements, elongated frame profile arrangements and holding parts are integrated in the same frame profile which is an extruded, moulded or pultruded profile.

14. The vacuum insulated glass unit frame assembly according to claim 1 , wherein said flexible connection arrangements comprises a plurality of discrete flexible wall members distributed in the longitudinal direction of the edge of the vacuum insulated glass unit to which the flexible wall members are connected.

15. The vacuum insulated glass unit frame assembly according to claim 1 , wherein the magnitude of the thermal deflection of the edges of the vacuum insulated glass unit is configured to vary along one or more of the vacuum insulated glass unit edges between the corners where the respective edge terminates due to said temperature difference (ΔT=T 1 −T 2 ) between the two glass sheets, thereby describing an edge deflection curve relative to a frame opening plane defined between the elongated frame profile arrangements.

16. The vacuum insulated glass unit frame assembly according to claim 1 , wherein all four edges of said vacuum insulated glass unit are allowed to thermally deflect in a deflection direction perpendicular to the frame opening plane defined between the elongated frame profile arrangements due to a temperature difference (ΔT=T 1 −T 2 ) between the two glass sheets.
