Abstract:
In exchangeable spectacle frames, in which the side arms and bridge are fastened to the lenses or central part of the spectacle frame by a support element, the support element is a rod-shaped, rail-shaped or plate-shaped metal part with a metallic threaded pin and an additional metallic positioning pin or threaded pin. The metallic or plastic end of the side arm on the side of the lens, or the connecting element between the support element and metallic or plastic side arm, is shaped with recesses which are adapted to the form of the support element, have the same length as the metallic part and engage the metallic part. The recesses in the side arm form at least two catches on the lateral, inner plastic interfaces which interact with the threaded pin and positioning pin. Alternatively, the side arms or bridges are made of an elastic material with a slit-shaped recess, in which recesses are located for form-fittingly receiving the pins of the support element and locking them after their insertion.
