<p>This invention refers to a way of production frames for glasses of different types but all with the characteristic of noting weldings and without the hinge that normally joint frontal with bars because such purpose has absolved from the elasticity of the material. During the same productive process will be realized also the exhibitor for the point of sale, reducing costs, times and waste. Besides, with a couple of prescription or sun lenses, however expensive, it will be possible to preserve while the frame will be replaceable having disposition different compatible with the couple of lenses. Frontal, bars and hold nose, that is all the structure of the glasses, has made in the same time from one metallic plate. Through varied techniques between which the cut laser, the electroerosion and good still the photo-chemical machining technique, comes worked the metallic plate that subsequently will be folded up in the opportune way because engage the definitive shape. A part of the plate will give birth to the frames for glasses, an other will be used for the examples of color, while the remainder part that contains the all, are used like exhibitor of the same glasses once folded up in the correct way. Part of the bending comes transmitted to the frames, that have the right thickness to the purposes, from the same lenses with negative chamfer you insert in the elastic joint with the correct shape. The compactness of the frames and of the exhibitor not folded up they facilitate the delivery and the store of the collection. Besides, for remove the problem of hold the folded up glasses, will be employed a tubular scabbard of plastic transparent material, in which the glasses will put in.</p> |
