Abrégé

The present invention relates to a spring hinge (10) intended to hinge together a side arm (11) and a front piece (12) of a frame for spectacles (13). The spring hinge (10) comprises a swivel piece (14) having a front pivoting end (16) and a rear wall (18); the swivel piece (14) is provided with an open cavity (20) which seats inside it an anchoring element (22) which has, fitted thereon, elastic means (24) acting between a front end portion (26) of the anchoring element (22) and the rear wall (18). In accordance with the invention, the anchoring element (22) is seated inside the cavity (20) so that its rear portion (28) projects from the swivel piece (14) through a recess (30) formed in the rear wall (18) of the swivel piece (14). The invention also relates to a frame comprising such a spring hinge (10) and to a method for assembling this spring hinge (10).

A spring hinge for spectacles comprises a casing (11, 311) which slidably houses a hinge element (13, 113, 313, 413, 513, 613, 713, 813, 913) which has a front pivoting end (14, 114, 214, 314, 514, 614, 714, 814, 914) and extends inside the casing in the sliding direction as far as a rear end thereof (16, 116, 216, 316, 516, 616, 716, 816, 916). Resilient means (17, 317, 417, 817, 917) contained inside the casing act against this rear end so as to resiliently push the hinge element. At least one section of the hinge element which terminates in the rear end is formed by elements arranged adjacent and in lateral contact with each other (13a,b;. 113a,b; 313a,b; 413a,b; 513a,b; 613a,b; 713a,b; 813a,b; 913a,b). A manufacturing method is also described.

The present invention proposes the production of a structural element 10 suitable for being used for assembly of the frames 100 of glasses, said structural element 10 being particularly suitable for rigid fixing to a connection element 20 of said frame 100 such as a hinge element or similar, said connection element 20 being suitable for connecting said structural element 10 to a second structural element 30 of said frame 100. In particular, the present invention proposes direct formation, on a structural element of the type just described, of at least one fusion portion 11 shaped and sized so as to be suitable for being fused by electrowelding, thus permitting the rigid fixing of said structural element 10 to said connection element 20 of said frame 100.

The present invention is a joint shaped like an elastic miniaturised hinge (10) suited to be used in eyeglasses, comprising a first element (11) suited to be fixed to the front portion (101) of a pair of eyeglasses (100), and a second element (13) suited to be fixed to one of the temples (102) of the eyeglasses; said first and second elements (11, 13) are rotatingly fixed to each other by means of a shaft (23), a first end portion (25) of the shaft (23) being rotatingly fixed to the first element (11), a first intermediate portion (41) of the shaft (23) adjacent to the first end portion (25) being suited to be housed in a through hole (17) made in the second element (13). A second intermediate portion (40) of the shaft (23) adjacent to the first intermediate portion (41) on the portion opposite the first end portion (25) is housed in the internal space defined by helical elastic means (27) kept in position by fixing means (28) applied to the shaft, so that the rotation of the shaft (23) and therefore of the second element (13) with respect to the first element (11) is counteracted by the action of the elastic means (27).
