VACUUM MULTILAYERED GLASS PANEL
Document Type and Number:
WIPO Patent Application WO/2021/182099
Kind Code:
A1
Abstract:
This vacuum multilayered glass panel 10 comprises a first glass plate 11, a second glass plate 12, a sealing part which forms a vacuum-sealed gap 13 between the first glass plate 11 and the second glass plate 12, and a plurality of columns 16 which are disposed between the first glass plate 11 and the second glass plate 12. The column 16 has abutting surfaces 21 which abut on the facing surfaces 17 and 18 of the first glass plate 11 and the second glass plate 12, and non-contact portions 23 which are formed around the abutting surfaces 21 and separated from the facing surfaces 17 and 18 of the first glass plate 11 and the second glass plate 12. The non-contact portions 23 are configured so that, when the first glass plate 11 or the second glass plate 12 facing thereto is deformed by the application of a first external force, then the non-contact portions 23 can at least partially abut on the deformed first glass plate 11 or second glass plate 12.
