[0015] In order to complement the description that is being made and for a better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part of it, by a drawing in which the following has been represented with illustrative and not limitative character:

[0016] FIG. 1.Shows an exploded perspective view of the hinge mechanism for glasses, object of the invention, where one can appreciate the parts and elements it comprises, as well as the configuration of each.

[0017] And the FIG. 2.Shows an elevation view of the hinge mechanism for glasses, according to the invention, shown in FIG. 1, represented here once its parts and elements are coupled to each other, where one can appreciate the arrangement of each.

PREFERENTIAL EMBODIMENT OF THE INVENTION

[0018] In view of these figures, and in accordance with the numbering adopted, an example can be seen in them of the non-limitative implementation of the hinge mechanism for recommended glasses, which comprises the parts and elements indicated and described in detail below.

[0019] FIG. 1 shows how the mechanism (1) in question comprises ends (2), on the respective sides of the front part (3) of the frame, fitted with means of reception (23, 24), flexible ends (4) on the temples divided into tridents, fitted with means of insertion (44, 45), and a coupling connector (5) which is fixedly assembled to the ends (2) of the front part (3) of the frame, and to which they are assembled, with a mobile and flexible union which makes it possible to turn the temples with respect to the front part (3) of the frame, the flexible ends (4) of these temples.

[0020] For this purpose, the terminations (2) are formed by a platen (21) that emanates, on each side of the front part (3) of the frame, with a round trip segment that forms a distal loop (22) that defines a window (23) suitable as a means of receiving one of the means of insertion (45) of the trident into which the flexible ends (4) of the temples are divided.

[0021] In addition, above and below the platen (21), there are slots (24) drilled, suitable as a means of receiving other means of insertion (44) of the trident into which the flexible ends (4) of the temples are divided.

[0022] For this purpose, the trident into which the flexible ends (4) of the temples are divided is composed of a central tab (41), coplanar to the plane of the temples, and two parallel extensions (42), upper and lower, and turned ninety degrees with respect to the plane of the central tab (41), from which they are separated by respective intermediate spaces (43).

[0023] The central tab (41), which is approximately the same length as the parallel extensions (42), has a series of zigzag angled folds (45) as insertion means that fit into the window (23) that determines part of the means of receiving the terminations (2), while the distal ends of the parallel extensions (42) have respective hook formations (44) as insertion means in the slots (24) that determine the remaining means of receiving the terminations (2).

[0024] Finally, the coupling connector (5) is configured as a prismatic body which, at one end, has a longitudinal lateral opening (51) suitable for the reception and insertion into it of the terminations (2), specifically of the distal loop (22) with the window (23), and which also has a transverse gap (52) to which this lateral opening (51) is opened and which, by assembling the elements of the mechanism (1) as shown in FIG. 2, coincides with the aforementioned window (23), being suitable for receiving the central tab (41) of the flexible ends (4) of the temples, fitting into them their angled zigzag folds (45).

[0025] The opposite end to the side opening (51), the one facing the temple, is blind and, preferably, has a curved-concave surface (53) that facilitates the sliding of the trident components of the flexible end (4) of the temple when turning in the opening movement of the temple.

[0026] Preferably, moreover, the front face of this prismatic body which constitutes the coupling connector (5) has a recess (54) in the shape of a longitudinal channel, in which the distal end of the central tab (41) is fitted.

[0027] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages derived from it, stating that, within its essentiality, it may be put into practice in other embodiments that differ in detail from that indicated by way of example, and to which the protection it requests will equally be attained, provided that its fundamental principle is not altered, changed or modified.
