Frame solution providing reduced deflection restriction at corner parts of vig unit

A vacuum insulated glass unit frame assembly, wherein said vacuum insulated glass unit frame assembly comprises:

• a rectangular vacuum insulated glass unit comprising 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 extending in a frame opening plane defined between the elongated frame profile arrangements, and wherein said frame comprises a fixation system fixating the vacuum insulated glass unit at the frame,
• wherein said fixation system is arranged so as to allow edges of said vacuum insulated glass unit to thermally deflect in a deflection direction perpendicular to said frame opening plane due to a temperature difference between the two glass sheets,
• wherein said fixation system is configured to allow the magnitude of said thermal deflection to vary along the edge between the corners where the respective edge terminates,
• wherein said fixation system is arranged to provide a resistance against said thermal deflection of at least two opposing edges of said vacuum insulated glass unit, said resistance being substantially lower at corner parts of the edges than at centre parts of the edges, whereby the ratio of between the compression force on the fixation system and the and the thermal deflection at positions at the corner parts is less than half of the corresponding ratio at the centre part of an edge, and
• wherein said centre parts of said at least two opposing, parallel edges constitute at least a third of the extend of the edge between said corners.

The retrofitting frame system for retrofitting a vacuum insulated glass unit to an frame originally designed for insulated glass panes of greater thickness than the thickness of the vacuum insulated glass unit, wherein said retro-fitting frame system at least comprises:

• a 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 plurality of elongated frame profiles each comprising a recess defined between walls of the frame profile for receiving an edge of the vacuum insulated glass unit, wherein said recess extends the longitudinal direction of the frame profile, and wherein said plurality of elongated frame profiles are configured to be attached to said frame,
• one or more resilient, elongated tightening seals/gasket arrangements configured to follow a deflection of the vacuum insulated glass unit when it thermally deflect, so as to provide a water tightening and/or air tightening of a space provided between one or more frame profiles members and an outer surface of the vacuum insulated glass unit when installed at said frame,
• a fixation system configured to fixate the vacuum insulated glass unit in/at said recess of the frame profiles,
• wherein said vacuum insulated glass unit is configured to extend in a frame opening extending in a frame opening plane defined between the plurality of frame profiles,
• wherein said fixation system is arranged so as to allow edges of said vacuum insulated glass unit to thermally deflect in a deflection direction perpendicular to said frame opening plane due to a temperature difference between the two glass sheets, and
• wherein said fixation system is configured to allow the magnitude of said thermal deflection to vary along the edge between the corners where the respective edge terminates,
• wherein said fixation system is configured to provide a resistance against said thermal deflection of edges of said vacuum insulated glass unit, said resistance being substantially lower at corner parts of the edges than at centre parts of at least two opposing edges, and
• wherein said centre parts of said at least two opposing, parallel edges constitute at least a third of the extend of the edge between said corners.
