A hinge for the articulated joining of eyeglass frame temples to their respective end pieces of the front of the frame, without requiring welding of eyelets or of other joining parts to the end pieces of the front and temple. The hinge is constituted by a pair of independent outer eyelets engaged with two tines provided at the hingeing end of the temple, and by a middle eyelet (10) engaged with two tines provided at the two side hingeing end pieces of the front of the eyeglass frame. The middle eyelet includes two coaxial cavities with contoured bottom surfaces that define circular or radial cams, these surfaces rotating and sliding on corresponding and mutually opposed radial cam surfaces of the outer eyelets which, with the rotation of the temples with which they are associated, cause an axial translational movement of those outer eyelets. |
