A frame for spectacles includes a frontal framework with lateral lugs for articulation of arms and means of articulation between each lug and the corresponding arm. The articulation means include a flexible member, structurally independent of the lug and the arm, the flexible member being held on the arm and coupled rotatably, the end of each arm, facing the corresponding lug, shaped in such a manner that the arm, in its movement about the hinge pin, is flexibly constrained towards preselected angular positions relative to the frontal framework. The frame also includes a respective distance element interposed between each arm and the corresponding flexible member, and said distance element is mounted on the arm in an adjustable manner in order to impose, at the level of said distance member, a preselected distance between the arm and the flexible member, and to regulate a flexible pre-load exerted on the flexible member.
A frame for spectacles comprising a frontal framework (2) with respective lateral lugs (4) for the articulation of respective arms (5) and means of articulation between each lug (4) and the corresponding arm (5) for the articulated connection of the respective arm to the frontal framework, said articulation means comprising, for each arm (5), a flexible member (9), structurally independent of the lug (4) and the arm (5), said flexible member (9) being held on the arm (5) and coupled rotatably with at least one hinge pin (7) provided on the corresponding lug (4), the end of each arm (5), facing the corresponding lug, being in contact with a surface profile of said lug (4), shaped in such a manner that the arm (5), in moving about the hinge pin (7), is flexibly constrained towards preselected angular positions relative to the frontal framework (2), said angular positions including an open position of the arm (5), suitable for wearing the spectacles, and a closed position of the arm (5) folded on to the frontal framework (2), the frame comprising, for each arm (5), a respective distance element (15) interposed between each arm (5) and the corresponding flexible member (9), said distance element (15) is mounted on the arm (5) in an adjustable manner in order to impose, at the level of said distance member (15), a preselected distance between the arm (5) and the flexible member (9), and consequently to regulate a flexible preload exerted on said flexible member (9) when coupled rotatably with the hinge pin (7).
