Spectacles e.g. optical glasses, has transformation units mounted on spectacles as result of their elastic deformation due to traction or manual pressure in order to reduce distances relative to each other and engage hooks in notches

摘要

The spectacles has complementary fixing units including two notches (15A) situated in temporal zones and two hooks (16A) formed at ends of transformation units at a distance (D) equal to another distance (D`) that separates the notches. The transformation units are mounted on the spectacles as a result of their elastic deformation due to a traction or a manual pressure in longitudinal or transversal direction in order to reduce the distances with respect to each other and engage the hooks in the notches.
