  • Patent number: 6479112
    Abstract: A glass panel, its manufacturing method and a spacer for use in the glass panel. In the glass panel, a plurality of spacers (3) are formed between and along a first opposing face (2A) of a first glass sheet (1A) and a second opposing face (2B) of a second glass sheet (1B) so as to form a space (C) therebetween, and a sealing material (6) is provided at peripheral edge (1a) of the first glass sheet (1A) and the second glass sheet (1B) for maintaining the space (C) gas-tight. The plurality of such spacers (3) having, at one side thereof, contact portions (5) capable of coming into contact with the first opposing face (2A) are provided on the second opposing face (2B). The contact portions (5) and the first opposing face (2A) are movable relative to each other.

  • Publication number: 20020110653
    Abstract: A glass panel including a pair of first and second glass sheets (1A, 1B) disposed with sheet faces thereof opposed to each other, a plurality of spacers (5) being interposed between the pair of glass sheets (1A, 1B) for forming a space (4) therebetween; and a sealing material (S) for bonding peripheral edges (3) of the glass sheets (1A, 1B) together for sealing the space (4), the sealing material having a lower fusing temperature than the softening point of the glass sheets (1A, 1B). Each spacer (5) is formed by disposing spacer-forming paste (11) in a predetermined shape on the sheet face of the glass sheet (1A, 1B). Or, the spacer (5) comprises a plurality of spacer bodies (51) two-dimensionally interconnected to each other via a connecting member (52).
