Patent ID: 7992995

Claim:
Spectacles including an optical or solar facade connected to two sidepieces which are each connected to the facade by a central rotational pin which is substantially perpendicular to the facade and which is used to rotate each sidepiece on itself between a use position and a storage position in front of the facade, which has a radius of curvature substantially equal to that of the respective sidepiece, each said sidepiece being divided into two parts including a first part fastened to the central rotational pin and a second part connected to the first part by intermediate translational drive means disposed between the first and second parts and progressively acting on the second part during the rotation of the first part and consequently the second part so as to subject the second part to two combined movements, wherein one of the movements is rotational and another of the movements is linear, for automatic and simultaneous lengthening of a respective one of said sidepieces as the respective sidepiece is turned toward a use position and shortening of the respective sidepiece as the respective sidepiece is turned toward a storage position.
