| 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.

What is claimed is:
1. A device for fixing lenses in the bezel rims of an eyeglass frame having a lens-receiving opening whose shape corresponds to the shape of the lens, allowing easy and repeated mounting and removal of said lenses on to and from the frame, wherein the bezel of the frame rim has a concave polygonal shape in cross-section, said device comprising a metal ring having a width substantially equal to that of the bezel adapted to encircle and grip the lens around its periphery and to, in turn, be inserted into the bezel rim, said metal ring having a rounded convex external edge whereby, when viewed in crosssection, there is point contact between said external edge and the bezel when the ring/lens assembly is set in the bezel rim.
