Abstract: A spectacle hinge is disclosed of the type including a male component and a female component, mutually coupled according to a hinge axis, as well as an elastic element fastened to the female component and elastically compressed against an eyelet of the male component, the eyelet having abutting sectors parallel to the hinge axis against which the elastic element is intended to arrange itself elastically.

Abstract: An elastic hinge member (10) for spectacles rims, includes a guiding area (22), a slide (30) having a guided part (32) cooperating with the guiding area (22) and a knuckle (31) and a return spring (40). The spring (40) has a compressibility that is sufficient for allowing the guided part (32) to come out of the guiding area (22), and the slide (30) can pivot about the longitudinal axis thereof in order to remain blocked in an “out-blocked” position that facilitates the assembling or disassembling operations of the knuckle with a spigot.

Abstract: A glasses hinge and method to obtain said hinge is disclosed, of the type comprising a male portion (M) and a female portion (F), mutually connected by a small articulated pin (P), equipped with coupling surfaces, apt to define blocking positions while opening and closing, which are radial and, at least on one of the two portions, are obtained by removing material through mechanical machining.

Abstract: Front for full-rim glasses frames with a holding device and rapid fixing of the lenses to the frame. The front being of the type with a monopiece arch transversely projected with respect to the face of the user, which includes, at the temporal ends, two shaped and curved cross-pieces joined by a connecting intermediate nose bridge. Each cross-piece provides hinging of the related side, and each cross-piece near to the intermediate connecting nose bridge provides a curved projection, which provides a first of the two ends of flexible holders that partially enclose the peripheral edge of the lens to be joined to the front, the other side being provided with a second end, introduced by a through-hole obtained in correspondence to the temporal region of the front, that is equipped with a tooth that engages unidirectionally the portion of the second end of the flexible holders.

Abstract: A simplified hinging device and a temple bar thereby obtained, particularly for eyeglass frames, includes a prevalently metallic termination, which is widened, contoured, holed and bent according to a U shape, which engages, by means of a pivoting screw or one or more projections, another prevalently metallic termination, which is widened, contoured and holed, free to rotate about the axis of the aforesaid screw, pivot point or projection.

Abstract: Procedure to form a permanent tip in polymer, formed directly in correspondence with the end portion of a support arm in metallic wire for spectacles, in which a work cycle foresees at least the following phases: (a) preparation of a bath with a liquid solution which includes a polymer; (b) immersion in the bath of at least the end portion and, in the first case, of a support arm in metallic wire for spectacles without a coating; (c) removal of the support arm in metallic wire from the bath, according to a pre-determined speed; (d) movement of the support arm towards a solidification station for the solidification of the portion immersed in the bath; (e) if required, repetition of at least phases (b), (c) and (d). The support with the end coated by the polymer tip form a single piece with, at one end, a progressive reduction for the thickness of the tip which has been formed before the end of the support arm, and if required, with an enlargement of the end of the tip in the form of a droplet.

Abstract: Spectacles assembly with a bow-shaped frame and support clip for an interchangeable frontal lens holder. The assembly includes: a bow with arms, for the support of the frontal lens holder; a frontal lens holder made out of profiled material, where the said material goes around at least a part of the outer edge of the lens; and a device with a flexible movement, used to join the frontal lens holder to the bow. The flexible device is formed in correspondence with the connection bridge between the two arch-shaped sections which make up the bow. The frontal closed-ring lens holder has a connection bridge between the peripheral support of the lenses, with the bridge being hooked by a clip which is formed monolithically by the bow.
