Abstract

Disclosed are apparatuses for shaping a glass structure, the apparatuses having a plurality of rib members, each rib member comprising at least one void and at least one shaping edge; and at least one support member. The apparatuses can further comprise a shaping member and/or a guide member and/or a shaping groove. Also disclosed herein are methods for shaping a glass structure, the methods comprising positioning the glass structure on a shaping apparatus and heating the glass structure to shape the glass structure.

First claim

What is claimed is:

1. A glass shaping apparatus comprising:
a plurality of rib members, one or more rib members comprising at least one void and at least one shaping edge;
at least one guide member connected to at least one rib member, said at least one guide member comprising at least one shaping edge substantially matching a shape or a curvature of the shaping edge of the at least one rib member;
at least one support member connecting at least two members of the plurality of rib members and at least one guide member; and
a shaping member proximate one or more of the shaping edges of the rib members, the shaping member having at least one first curvature that substantially matches at least one first curvature of the shaping edges,
wherein at least one shaping edge of at least one rib member and at least one shaping edge of at least one guide member are configured to define a shaping groove, and
wherein the shaping member is disposed in or otherwise affixed to the shaping groove.

2. The apparatus of claim 1 comprising:
(a) an array of rib members, each of the rib members comprising a plurality of voids and at least one shaping edge; and
(b) at least one support member extending through at least a portion of at least one void in a direction transverse to a vertical axis of the array of rib members,
wherein the shaping edges of at least two of the rib members collectively form a non-planar surface.

3. The apparatus of claim 2 , wherein the shaping member is disposed on the non-planar surface of the array of rib members, and substantially conforms to the shape of the non-planar surface of the array of rib members.

4. The apparatus of claim 1 , wherein the shaping groove is configured to bias the support member with respect to one or more shaping edge of at least one rib member.

5. The apparatus of claim 1 , further comprising at least one connector, wherein the at least one connector is configured so that one or more shaping grooves bias the support member with respect to one or more shaping edges of the guide member.

6. The apparatus of claim 1 , wherein the rib members comprise metal chosen from steel, stainless steel, cold rolled steel, and aluminium.

7. The apparatus of claim 1 , wherein the rib members have a thickness ranging from about 0.1 to about 5 mm.

8. The apparatus of claim 1 , wherein the shaping member has a thickness ranging from about 1 micron to about 2 mm.

9. The apparatus of claim 8 , wherein the shaping member has a thickness ranging from about 0.1 mm to about 0.5 mm.

10. The apparatus of claim 1 , wherein the shaping member comprises metal foils, metal fabrics, glass fabrics, ceramic fabrics, metal papers, glass papers, ceramic papers, and combinations thereof.

11. The apparatus of claim 1 , further comprising at least one vacuum chamber configured to apply vacuum conditions to a portion of the shaping member, wherein a portion of the shaping member comprises through-holes.

12. The apparatus of claim 1 , wherein at least one of the support members comprises a curved shaping edge configured to impart a second curvature to the shaping member.

13. The apparatus of claim 12 , wherein the first curvature and the second curvature extend in substantially perpendicular directions.

14. The apparatus of claim 1 , further comprising an insert disposed between the rib members and configured to impart a three-dimensional shape to the shaping member.

15. A method for shaping a glass structure comprising heating a glass structure disposed on a shaping apparatus according to claim 1 .

16. The method of claim 15 , wherein the heating comprises heating the glass structure to the softening temperature of the glass material.

17. The method of claim 16 , wherein the shaping is facilitated by the application of vacuum or weight to the shaping member and/or glass structure.
