ABSTRACT:
A spring hinge for spectacles is described having a central hinge lobe (4) guided so it is displaceable in a bow-side housing (1) in the bow longitudinal direction and having a U-shaped sliding part (3) projecting from the hinge lobe (4) in the displacement direction and engaging in a housing recess (2), which receives a coiled spring (10) between its two legs (7), which is supported at one end on the web (6) connecting the two legs (7) of the U-shaped sliding part (3) and at the other end on a buttress (11), which is held removably in the housing (1) by a rotational adjustment coaxial to the coiled spring (10), the hinge lobe (4) having a through opening (17) running coaxially to the coiled spring (10). To allow a narrow construction for the spring hinge, it is suggested that the buttress (11) inserted transversely to the displacement direction between the legs (7) of the sliding part (3) have a greater diameter than the through opening (17) provided in the hinge lobe (4) for the insertion of a tool for the rotational adjustment of the buttress (11).
