Patent attributes
A spring hinge between a bow cheek and a bow of a pair of spectacles is described, having two hinge parts (3, 4), which are each associated with one of these spectacle parts (1, 2), one of which forms a bearing fork (6) having a hinge axis (5) for receiving the other hinge part (4), which is guided so it is displaceable in a housing (9) with the aid of a U-shaped sliding part (7), and having a coiled spring (12) situated between the two legs (11) of the sliding part (7), which is supported on one side on a web (13) of the sliding part (7) connecting the two legs (11) and on the other side on a buttress (14), which engages through a through opening (16) of the associated hinge part (4), which runs coaxially to the coiled spring (12), in a nut thread (15) of the housing (9) which is coaxial to the coiled spring (12). In order to provide advantageous construction and installation conditions, it is proposed that the hinge part (3) forming the bearing fork (6) forms an insert which is inserted so it is removable in a laterally closed receptacle pocket (17) of the associated spectacle part (1).
