发明名称 Curved glazed panels
摘要 A thermally-tempered, cold curved panel having a sheet of glass, including a resiliently-flexed curvature, and a frame which is adapted to maintain the curvature of the sheet of glass under constraint, as well as a method and a device for producing the curved panel, is disclosed. The frame of the panel includes straight frame sections and curved frame sections which are secured to the sheet of glass, retaining the curvature of the sheet of glass under constraint. The sheet of glass is thermally-tempered being cold-curved at a temperature being between 80 DEG C. and 140 DEG C., such that a resiliently-flexed curvature is formed therein. The curvature is maintained under constraint by a special device while the frame is assembled about the edges of the glass. Once assembled, the frame maintains the curvature of the thermally-tempered sheet of glass under constraint. The device which permits curving is a template having an upper curving surface having substantially the same curvature as that desired for the final product. Suction discs, carried by jacks are secured to parts of the glass not contacting the curving surface. Movement of the jacks with the suction discs carried thereon provide the force for the curving operation.
