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

Abstract

A vacuum insulated glass (VIG) unit frame assembly () is disclosed, comprising: a rectangular vacuum insulated glass unit () comprising two glass sheets () separated by a sealed gap (), wherein a plurality of support structures () are distributed in said gap (), and a frame () comprising elongated frame profile arrangements (-) which frames said vacuum insulated glass unit () in a frame opening (), 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 (DIS) in a deflection direction (D, D) perpendicular to said frame opening due to a temperature difference (ΔT=T−T) between the two glass sheets (), wherein said fixation system () is configured to allow the magnitude of said thermal deflection (DIS) 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 (DIS) 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 (-), and wherein said centre parts of said at least two opposing, parallel edges (-) constitute at least a third, such as half of the extend of the edge (-) between said corners ().
