Spring hinge for spectacles

摘要

The invention relates to a spring hinge for spectacles which is intended to press the spectacle bow beyond the stop position for the purpose of bearing resiliently against the wearer's head. It consists of a bow hinge and a middle-part hinge which are joined in an articulated manner to one another. By means of a slide part, the bow hinge can be displaced against spring action relative to the spring receptacle and guide on the end of the spectacle bow. Provided on both sides in the bow recess are guide grooves, in which a blocking member can be inserted as spring stop facing the bow end. The blocking member is formed by a pivot pin which has lateral wings and which can be inserted into the spring receptacle at right angles to the spring axis when the lateral wings are situated longitudinally and can then be inserted with one bolt end into a blind bore on the base of the guide and can be latched in this position by swivelling the lateral wings into the guide grooves on both sides, and thus serves as a spring stop. <IMAGE>
