Title: Continuous frames of glasses from metallic plates
IPC: G02C1/06
Filed: 2000-02-02
Abstract: This invention refers to a way of producing frames for glasses of different types but all with the characteristic of lacking in weldings and in the hinge that normally joints the frontal with the bars since such a purpose has been absolved by the elasticity of the material. During the same production process also the exhibitor for the point of sale will be realized, thereby reducing costs, times and wastes. Besides, with a couple of spectacle or sun lenses, even if expensive, it will be possible to preserve them, while the frame will be replaced by a different one compatible with the couple of lenses. Frontal, bars and nose pads, that is all the structure of the glasses, are made at the same time from one metallic plate. Through different techniques such as the laser cut, the electric erosion and above all the photo-chemical etching technique, the metallic plate is worked and subsequently is folded up in the suitable way to achieve the definitive shape. A part of the plate will generate the frames for glasses, and another part will be used for the samples of color, while the remaining part that contains the whole will be used like an exhibitor of the same glasses, once folded up in the correct way. Part of the bending is transmitted to the frames, that have the right thickness for the purpose, by the same lenses with negative chamfer to be inserted in the elastic joint with the suitable shape. The compactness of the frames and of the exhibitor, when not folded up, facilitates the delivery and the storage of their collection. Besides, for removing the problem of holding the folded up glasses, a tubular sheath of plastic transparent material, in which the glasses will be put in, will be employed.
