Embodiment Construction

[0037] refer to figure 1 , the spectacle frame that will now be described comprises: a front side 1 prepared for receiving optical lenses generally, and a right side part 2 and a left side part 3, in the example shown, the right side part 2 is in the closed position Lay down against the rear of the front side 1 , while the left side piece 3 is in the open position, substantially perpendicular to the general plane of the front side 1 . The front side 1 extends laterally substantially at right angles through the two front side lateral tenons 4, 5, the side parts 2, 3 are articulated between the two hinges 6, 7 - here called telescopic hinges. The front side faces onto the tenon.

[0038] The telescopic hinge - for example the left hinge 7 - comprises: a front side piece element 8 integral with the front side tenon 5, and a side piece element integral with the side piece 3 - more precisely with the central part 10 of this side piece 9. Side pieces are formed on the central port...

Abstract

The invention relates a frame which comprises a front surface, extended by two lateral posts and two arms hinged to the posts about the hinge pins (11) of two telescopic hinges (6, 7), each of which, with a front surface element (8) rigidly connected to a post and an arm element (9), is rigidly connected to an arm that comprises a slide hinged on the front surface element (8), and mounted in a sheath against a spring and slidable by means of the latter; the front surface element (8) and the sheath (13) of the arm element (9) engaging, in the open position of the arm, by at least two matching transverse surfaces (24) for stopping the opening. The surfaces (24) that stop the opening of the two elements (8, 9) of each hinge are rough, the surface (24) that stops the opening of one of the elements, of the surface, and of the arm (8, 9) having a hollow intermediate area (27). Thanks to the invention, the frame hinges have a reduced size with the same performance.

Description

technical field [0001] The field of the invention relates to spectacle frames. Background technique [0002] The spectacle frame comprises a front side and two side pieces, each side piece is hingedly mounted on a side tenon of the front side by a hinge. [0003] In the open position, the spectacle side pieces extend substantially at right angles to the general plane of the front side. [0004] A retractable hinge allows the side pieces to be opened beyond such a right angle. Due to this "over-opening", it provides more comfort when the spectacle frame is worn on the nose, and it excludes the risk of breaking or deforming the spectacle frame and side pieces. [0005] Retractable hinges for eyeglass frames usually include springs to hold the side pieces against the head, but just allow the mechanism to open too far. [0006] Telescoping hinges generally consist of two elements assembled on the hinge shaft and integrally formed respectively with the front side tenon (front ...
