Elastic link partic. for spectacle ear-piece - comprises hook firmly connected to front part and open eyelet in which pin is located

摘要

The link has a front part (11) to which is movably connected an ear-piece (23) together with a spring element (30), such parts being connected to one another removably and exchangeably without fixture means. The end (20) of the ear-piece is connected by the flexible pressure of the spring element (30) with a hook (10) of the front part (11), whereby the spring element inserted in a blind hole is bent and locates against the edge of a convolution (13) and holds firmly a pin (25) in an open eyelet (12) of the hook (10). Through the effect of the bending of the spring element (30) by contact with the outer edge of the hook, the spring element stable position in its blind hole is maintained, whereby its bending deflection is guaranteed by the presence of a groove. USE/ADVANTAGE - For the sprung connection of a spectacle ear-piece and frame, involving a low number of parts.
