Chord of glasses and concatenated manner of front and hinge of glasses

摘要

(57) Abstract Role of fixing of the chord to on the front and role of revolution of the chord for the front are distinguished in the chord of the glasses frame due to this invention and the concatenated manner of the front, are separated. In the same way, the front (1) the chord to above (5) the fixed axle for this same front (1) the chord (5) is distinguished from the revolving shaft according to this invention, in the hinge of the glasses, is separated. As for the revolving shaft it is implemented (5) by the ball and socket coupling where you can install the chord. The natural or artificial ruby, the ceramics, the spinel and the silicon carbide, the zircon, and so on especially being hard, as for the ball and socket coupling of the callous which is implemented by the ball and socket coupling of the material make which has endurance, sphere (40) or base can take the forma of the common duplex conical element, between the duplex sides board (20 and 22) is laid out.
