  • Device for the temporary fixing of lenses on a spectacle frame
    Patent number: 4971431
    Abstract: The invention relates to a device for fixing lenses in the bezel rims of a spectacle frame, allowing easy and repeated mounting and removal of these lenses on to and from the frame. The bezel of the frame rim has a concave polyganol shape in cross-section. A metal ring sets the lens definitively round its periphery and has a rounded convex external edge. As viewed in cross-section, the contact between this external edge and the bezel is therefore made at points when the ring/lens assembly is fitted in the bezel rim.
