Elastic miniatured hinge for flex temples, with box provided with at least a guiding zone for the connection of the articulation to a seat joined to the front of the glasses, including:

- a box;

- a housing along the box containing the articulation trolley;

- the articulation trolley, which includes at least one spring and which is contained inside of the box, while the articulation exits from the front end of the box;



in which, peripherally with respect to the opening of the housing obtained at the front end of the box, at least one guiding zone is obtained, said guiding zone consisting of a cheek of a protrusion longitudinally projected with respect to the box, where said cheek is parallel and oriented toward at least one of two lateral faces of the articulation, and furthermore in which said protrusion is provided with a guiding seat with opening along the front profile and longitudinally projected with respect to the sliding longitudinal axis of the articulation trolley.

Method for making a hinge (10) for spectacles comprising two articulation elements (13, 15), pivoted to each other and mounted respectively on a temple (11) and a lug (12) of a frame for the glasses. The method provides, for at least one of the articulation elements (13, 15) at least a first step of shaping/minting an element of crude material (20, 25), during which, by means of shaping/minting members (21, 26), the element of crude material (20, 25) is shapedhninted so as to achieve a semi-worked piece (22, 27) substantially having the final aesthetic form of the relative articulation element (13, 15); and a second finishing step, obtained by mechanical working, by means of removal of material, during which one or more workings of the semi-worked piece (22, 27) are made, in order to obtain the articulation element (13, 15).

A kind of resilient hinge for spectacle frames and a method of manufacturing same. Said resilient hinge includes at least an axis as well as a positioning guide, a resilient medium and a stopper, which are fitted over and through the axis in the aforesaid order. The spectacle frame front and temple can be correspondingly closed and opened conveniently and smoothly through the resilience generated by the resilient hinges provided between the spectacle frame front and the temple. The positioning guide is thus designer to maintain the stability of this process. Said method should at least include the following steps: to make the axis into its basic form from a metal sheet; to reduce the diameter size of the end portion of the said axis bearing the basic form and process it into a cylindrical shape with a specified diameter; a hole is provided at the top end of the axis to form a hinge hole. The axis formed will have a high level of brightness without any traces of pressing marks on its surface, the smooth stretching out and bouncing back of the spring is guaranteed. The density of metal molecule is uniform, free from stress concentration. This enhances the hardness, rigidity and stability of the axis. The entire length of the axis can be controlled freely according to structural requirements.

An elastic hinge, particularly for monobloc temples, comprising a lug (2) that that can be coupled to a front (3) of a frame for eyeglasses and is provided internally with a first spherical seat (5) and a second cylindrical seat (6), which are connected by a first duct (8) that is curved or inclined with respect to the longitudinal axis (4) of the lug (2). The hinge also comprises a connecting element (17) that can be inserted in a containment element (27) rigidly coupled to a temple (29) for frames of eyeglasses and can slide inside it in contrast with the action of elastic means (22). The connecting element (17) supports, at one of its ends that protrudes from the containment element (27), a spherical head (18) that can be inserted in the first seat (5) through the second seat (6) and the duct (8). A plug (35) can be inserted in the second seat (6) so as to prevent the accidental exit of the head (18) from the first seat (5), grooves (36) being further provided which are suitable to facilitate extraction of the plug (35) from the second seat (6) when required to allow replacement of a temple (29).

Charnière élastique pour monture de lunettes, comprenant un premier (1) et un deuxième (3) éléments de charnière possédant respectivement un premier (21) et un deuxième (7) charnons munis de perçages (23,25A,25B) pour recevoir un axe d'articulation (5) lorsque le deuxième charnon (7) est engagé entre deux portées (21A,21B) du premier charnon (21) de façon telle à superposer les perçages suivant une même direction axiale (A) contre la compression d'un ressort (9) logé dans l'un des deux éléments de charnière.

L'axe d'articulation et non fileté et comprend deux têtes (5A,5B) et un corps (5C) solidaire des deux têtes pour être engagé en translation à travers les perçages (23,25A,25B) des charnons (7,21) jusqu'à ce que les deux têtes (5A,5B) soient reçues dans les perçages (25A,25B) des deux portées (21A,21B) du premier charnon (21), le corps formant par rapport aux deux têtes un décrochement (D) pour être reçu dans le perçage (23) du deuxième charnon (7) en décalant ce dernier (7) par rapport à la direction axiale (A) des perçages (25A,25B) du premier charnon (21) contre la compression du ressort (9).

Selon l'invention, les deux portées (21A,21B) du premier charnon (21) sont jointives le long d'un profil (27) intérieur à ce charnon s'étendant d'arrière (27A) en avant (27B) par rapport à la direction axiale (A) des perçages (25A,25B) dans un plan perpendiculaire à cette direction axiale (A).
