Abstract:
A hinge wing with flexing device for temples of eyeglasses, comprising a box-like element, to be projection-welded to a temple, inside which a portion of a male hinge element is rigidly coupled so that it can only slide axially, said male hinge element having a tip which is shaped like an axial pin surrounded by an elastic contrast means which acts by compression between a wider end of said tip and said box-like element, a portion of the male element protruding from the front of the box-like element for pivoting to a corresponding female element so as to form the articulation, said box-like element having, on the face to be welded to the temple, an opening for accessing its interior through which it is possible to insert, in a pre-assembled configuration, said elastic means and said portion of said male hinge element, wherein said male element is stably retained, with its corresponding portion, inside the box-like element exclusively by means of a radially deformable open elastic ring which is interposed, on said tip, between said elastic means and said portion of said male element that is coupled by side-fit mating to said box-like element, said ring being inserted in an adapted slot of said box-like element whose perimetric dimensions are smaller than the dimensions of said ring at rest, said ring being retained axially in said slot by its outer edge and radially by the pressure applied by its deformation produced by insertion.
