Abstract
The disclosure relates to fame constructions comprising a glass substrate and a curved surface defining at least one curvature, wherein the engagement of the glass substrate with the curved surface imparts a curvature on the glass substrate.
Claims20
A glass article comprising:
- a glass substrate comprising a first major surface and a second major surface;
- a connector layer;
- an adhesive layer disposed between the second major surface and the connector layer, wherein the adhesive comprises a thickness that is greater than or equal to 200 μm and less than or equal to 1 mm and a bezel width that is greater than or equal to 1 mm and less than or equal to 15 mm;
- and
- a frame configured to impose a shape onto the glass substrate and the connector layer via a rigidity of the frame, wherein:
- one of the connector layer and the frame comprises a plurality of mechanical restraints,
- the other one of the connector layer and the frame comprises a plurality of mechanical restraint receptacles engaging the plurality of mechanical restraints, and
- the engagement of the plurality of mechanical restraint receptacles and the plurality of mechanical restraints maintains the glass substrate and connector layer in a curved shape when the glass substrate is mechanically stressed.

- an adhesive layer disposed between the second major surface and the connector layer;
- and
- a frame configured to impose a shape onto the glass substrate and the connector layer via a rigidity of the frame, wherein:
- the frame comprises a thickness that is greater than or equal to 0.5 mm and less than or equal to 20 mm,
- the frame comprises a curved surface that is complexly curved with distinct radii of curvature in at least two regions or in at least two independent directions,
- one of the connector layer and the frame comprises a plurality of mechanical restraints,
- the other one of the connector layer and the frame comprises a plurality of mechanical restraint receptacles engaging the plurality of mechanical restraints,
- the engagement of the plurality of mechanical restraint receptacles and the plurality of mechanical restraints maintains the glass substrate and connector layer in a curved shape when the glass substrate is mechanically stressed, and
- as a result of being maintained in the curved shape by the engagement of the plurality of mechanical restraint receptacles and the plurality of mechanical restraints, the glass substrate and connector layer are bent into conformity with the curved surface of the frame.
