A glass panel, its manufacturing method and a spacer for use in the glass panel. In the glass panel, a plurality of spacers ( ) are formed between and along a first opposing face ( A) of a first glass sheet ( A) and a second opposing face ( B) of a second glass sheet ( B) so as to form a space (C) therebetween, and a sealing material ( ) is provided at peripheral edge ( ) of the first glass sheet ( A) and the second glass sheet ( B) for maintaining the space (C) gas-tight. The plurality of such spacers ( ) having, at one side thereof, contact portions ( ) capable of coming into contact with the first opposing face ( A) are provided on the second opposing face ( B). The contact portions ( ) and the first opposing face ( A) are movable relative to each other.

Glass panel and method of manufacturing thereof and spacers used for glass panel

A glass panel including a pair of first and second glass sheets ( A, B) disposed with sheet faces thereof opposed to each other, a plurality of spacers ( ) being interposed between the pair of glass sheets ( A, B) for forming a space ( ) therebetween; and a sealing material (S) for bonding peripheral edges ( ) of the glass sheets ( A, B) together for sealing the space ( ), the sealing material having a lower fusing temperature than the softening point of the glass sheets ( A, B). Each spacer ( ) is formed by disposing spacer-forming paste ( ) in a predetermined shape on the sheet face of the glass sheet ( A, B). Or, the spacer ( ) comprises a plurality of spacer bodies ( ) two-dimensionally interconnected to each other via a connecting member ( ).

Glass panel

In a double glazing including a pair of glass sheets,, a plurality of spacers,disposed between opposed sheet faces of the glass sheets,by a predetermined pitch, and a sealing member,interposed between the glass sheets,along the entire peripheries thereof, with a space V between the glass sheets being sealed in a vacuum condition, each spacer,is formed so as to maintain a predetermined distance between the glass sheets when subjected to a static normal external pressure normally applied thereto in the direction of sheet thickness and also to relieve stress through plastic deformation when subjected to an impact dynamically applied in the sheet thickness direction.
