Abstract: An elastic miniaturized hinge used in eyeglasses. A first element fixed to the front portion of eyeglasses, and a second element fixed to a temple of the eyeglasses, said first and second elements are rotatably fixed to each other by means of a shaft. A first end portion of the shaft rotatingly fixed to the first element, a portion of the shaft adjacent to the first end portion housed in a through hole made in the second element. A second portion of the shaft is housed in the internal space of a helical elastic and fixed to the shaft, so that the rotation of the shaft and therefore of the second element with respect to the first element is counteracted by the action of the helical elastic.

Abstract: Side arm for glasses structured for the reduction of clearance and with a highly slideable carriage, essentially including a small box, associated to the side arm by welding and preassembly. Two springs are housed on the inside the springs on one side having the end in abutment on the bottom of the small box and on the other side being arranged in abutment of the end of a tie-rod/carriage, with respect to which one is arranged adjacently per side. A tie-rod/carriage is substantially T-shaped presenting the anterior end, provided with a convenient articulation hinged to a corresponding nose provided on the frame of the glasses and in which at least one clearance compensation element is interposed between the bottom of the internal seat of the small box and the profile of the portion of tie-rod/carriage facing the bottom of the internal seat of the small box.

Abstract: An elastic hinge for eyeglasses, comprising an elongated box-like body provided with an open receptacle inside which a traction elastic element and a first hinge articulation element associated with the elastic element are inserted with the first hinge articulation element arranged to slide and pivoted to a second hinge articulation element for fixing to the eyeglasses; the first and second ends having both a larger diameter than the intermediate body of the elastic element; a longitudinal milling extending on the entire length of the box-like body, and being provided with an axial hole; the length of the elastic element when inactive being substantially equal to the distance between the bottom of the axial hole and the end of the milling.
