Abstract

Official abstract text for this publication.

The subject matter of this invention is a polygonal heat-insulating glass panel with straight edges and a flat surface, in which the two parallel flat glass panes ( 1 ) enclosing the inner space of the glass panel are connected to each other, at least on one side, by a transparent, hermetically sealed spacer ( 2 ), forming a closed frame with the other sides. The transparent spacer ( 2 ) is composed of an adhesive mould incorporating a transparent adhesive body ( 5 ) and an adhesive flange ( 6 ) applied between an outer edge sealing glass strip ( 4.1 ) and an inner edge sealing glass strip ( 4.2 ), where the width of the outer edge sealing glass strip ( 4.1 ) matches that of the glass panel, while the width of the inner edge sealing glass strip ( 4.2 ) closing the inner space of the glass panel matches that of the inner space of the glass panel. The ends of the flat glass panes ( 1 ) are chamfered to allow cutting through the adhesive flange ( 6 ) in a way that, at the edges of the flat glass panes ( 1 ), the sealing lip formed by chamfering touches the sealing surface 13 of the outer edge sealing glass strip ( 4.1 ) of the transparent spacer ( 2 ) pressed between the flat glass panes ( 1 ).

First claim

Opening claim text (preview).

The invention claimed is: 1 . A polygonal heat-insulating glass panel with straight edges and a flat surface, comprising: two parallel flat glass panes; a transparent spacer connecting the two parallel flat glass panes to each other, at least on one side of the glass panes, to form a closed frame with other sides of the glass panes, wherein: the two parallel flat glass panes and the closed frame enclose an inner space of the glass panel with a hermetic seal, the transparent spacer consists of an adhesive mould between an outer edge sealing glass strip and an inner edge sealing glass strip, the adhesive mould having a transparent adhesive body and an adhesive flange, wherein a width of the outer edge sealing glass strip matches a thickness of the glass panel, and a width of the inner edge sealing glass strip closing the inner space of the glass panel matches a thickness of the inner space of the glass panel, edges of the glass panes are chamfered to match the adhesive flange, and a sealing lip, formed by the chamfered edges of the glass panes, directly contacts a sealing surface of the outer edge sealing glass strip of the transparent spacer. 2 . The glass panel according to claim 1 , wherein the glass panes comprise sodium calcium silicate. 3 . The glass panel according to claim 1 , wherein the outer and inner edge sealing glass strips comprise tempered aluminium silicate glass or tempered sodium calcium silicate glass. 4 . The glass panel according to claim 3 , wherein the outer and inner edge sealing glass strips have a thickness of 0.4-2 mm. 5 . The glass panel according to claim 1 , wherein the transparent adhesive body and the adhesive flange comprise thermoplastic polyurethane or ethylene vinyl acetate (EVA). 6 . The glass panel according to claim 1 , wherein the chamfered edges of the glass planes having a bevel angle of 3-75°. 7 . The glass panel according to claim 1 , wherein the polygonal heat-insulating glass panel is rectangular.
