Abstract

PROBLEM TO BE SOLVED: To prevent spectacle temples from being opened more than needed and from being made no longer fittable to the face. SOLUTION: The spectacle temple 4 has a coupling 4a which is freely turnably screwed to a first coupling 3a of an endpiece 3 and a slit 4b for freely displaceably connecting an elastic arm 6. The elastic arm 6 freely turnably inserts an endless die 6a into a slit 4b of the spectacle temple 4 and screws an end side 6b to a second coupling 3b of the endpiece 3 by means of a screw 7. Accordingly, such elastic arm 6 can turn the temple without affecting the turning operation resistance (so-called jerking) of the spectacle temple 4 and the first coupling 3a of the endpiece 3 at all. Even if the temple 4 is attempted to be turned more than the same (outward), the temple 4 is returned (inward) by the elastic force of the elastic arm 6, as a result of which more than the needed opening is obstructed. The spectacles can thus be fitted to the face and the burden on the endpieces 3 can be lessened.
