(57) Abstract The elastic hinge for the glasses, the first flank (6), for example the male die knuckle (10) has for the destal of the chord, in addition the second flank (4), for example the mold knuckle (20) we have for the salient of the front framework, the mold knuckle is concatenated to the aforementioned male die knuckle the connecting shaft (12) by. When the first flank (6) the male die knuckle (10 '') rim cam form (13 and 15) is, the male die knuckle (10 '') the connecting shaft (12) the orifice for the aisle (11), aforementioned cam condition rim (13 and 15) the opening of the longitudinal direction which faces to one (16) with it has become. The opening (16) the spring which is enclosed (18), in order cam condition rim of the aforementioned male die knuckle the mold knuckle (20 '') to push to base, the aforementioned opening and the connecting shaft (12) with operation in between. When the second flank (4) the mold knuckle (20) rim of the eye hole is cam form, the first flank (6) the flat destal (14), the male die knuckle (10) in near, the complete penetration opening of the longitudinal direction (16) it possesses. The internal spine (34) outside having, the component (30), the first flank (6) the flat destal (14) touching to the big aspect, although sleeve the opening (16) both sides it has been overturned. The spring which is enclosed to the aforementioned opening (18), the slide member (30) the mold knuckle (20) in order to push to cam condition rim, the base and the spine of the aforementioned opening (34) with operation in between.
