Definitions

  • the crystallized glass curved plate is supported by the first support member and the second support member, and has a bent portion that is separated from the first and second support members.
  • the crystallized glass curved plate is produced by heating and crystallizing the crystalline glass curved plate.
  • the crystalline glass curved plate is placed on the flexible ceramic paper so that the bent portion of the crystalline glass curved plate is in contact with the bent portion of the flexible ceramic paper. It is preferable to mount it.
  • the first support member and the second support member are integrally provided.
  • FIG. 1 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate according to an embodiment of the present invention.
  • FIG. 2 is a schematic perspective view of a crystallized glass curved plate manufactured in an embodiment of the present invention.
  • FIG. 3 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate in the first reference example.
  • FIG. 4 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate in the second reference example.
  • FIG. 5 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate in the first modification.
  • FIG. 6 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate in the second modification.
  • FIG. 1 is a schematic cross-sectional view for explaining a method for producing a crystallized glass curved plate in the present embodiment.
  • FIG. 2 is a schematic perspective view of a crystallized glass curved plate manufactured in the present embodiment. In the present embodiment, a method for manufacturing the crystallized glass curved plate 1 shown in FIG. 2 will be described.
  • the first support member 11 is provided in a plate shape.
  • the first support member 11 extends obliquely downward toward the second support member 12 side.
  • the first support member 11 has a planar first support surface 11a extending obliquely downward toward the second support member 12 side. Accordingly, the first support member 11 has a function as a support member for the ceramic paper 13 and the crystalline glass curved plate 20 described later.
  • the second support member 12 is provided in a plate shape.
  • the second support member 12 extends obliquely downward toward the first support member 11 side.
  • the second support member 12 has a planar second support surface 12a extending obliquely downward toward the first support member 11 side. Therefore, the second support member 12 also has a function as a support member of the ceramic paper 13.
  • the lower end portion of the second support member 12 is connected to the lower end portion of the first support member 11. For this reason, the first support surface 11a and the second support surface 12a are substantially V-shaped in a side view.
  • the ceramic paper 13 is supported by the first support member 11 and the second support member 12. Specifically, one end portion of the ceramic paper 13 is fixed to the upper end portion of the first support member 11 by a fixing tool 14 a, and the other end portion is fixed to the upper end portion of the second support member 12. It is fixed by a fixing tool 14b. Other portions of the ceramic paper 13 are not fixed to the first and second support members 11 and 12. That is, portions of the ceramic paper 13 other than the fixing portions (fixing tools 14 a and 14 b) with respect to the first and second support members 11 and 12 can be displaced with respect to the first and second support members 11 and 12. .
  • the crystalline glass curved plate 20 is deformed in the crystallization process. This deformation reduces the radius of curvature of the bent portion 23 of the crystalline glass curved plate 20. Therefore, as shown in FIG. 3, the entire ceramic paper 113 is supported by the support members (first and second support members 111 and 112), the bent portion 123 of the crystalline glass curved plate 120, the ceramic paper 113, , The bent portion 123 of the crystalline glass curved plate 120 is deformed, the bent portion 123 comes into contact with the support member via the ceramic paper 113, and its own weight is the crystalline glass curved plate. The contact portion between the bent portion 123 and the support member is added via the ceramic paper 113.
  • the thickness of the ceramic paper 13 is preferably 0.5 mm or more, and more preferably 1.0 mm or more.
  • the thickness of the ceramic paper 13 is preferably 5.0 mm or less, and more preferably 2.0 mm or less.
