Abstract: A hinge wing (10) with flexing device for temples of eyeglasses, comprising a box-like element (11) which has, on the face (14) to be welded to the temple (12), an opening (24) for accessing its interior through which it is possible to insert, in a pre-assembled configuration, an elastic element (19) and the portion (16) of a male hinge element (17). The male element (17) is stably retained, with its corresponding portion (16), inside the box-like element (11) exclusively by a radially deformable open elastic ring (26) which is interposed, on the tip (18), between the elastic element (19) and the portion (16) that is coupled by side-fit mating to the box-like element (11); the ring (26) is inserted in an adapted slot (27) of the box-like element (11) whose perimetric dimensions are smaller than the dimensions of the ring at rest, and the ring is retained axially in the slot by its outer edge and radially by the pressure applied by its deformation produced by insertion.

Abstract: An elastic hinge for eyeglasses comprising, at the end of a temple, an eyelet-shaped element suitable to engage, by means of an articulation pivot, two elements having the same structure and protruding from the front. Starting from the eyelet-shaped element, the following elements are assembled in sequence on the temple: a slider with a spoon-shaped end; an elastic element; and a contrast element which extends with a hollow structure so as to conceal the elastic element and at least partially conceal the slider. An annular locking element is at least partially interposed between annular abutment regions of the contrast element and of the temple, is inserted from the free end of the temple and can be deformed elastically with its locking parts so as to move beyond the abutment region of the temple.
