ABSTRACT:
A spring hinge for spectacles is described having a hinge part (1) guided displaceably in a bow-side housing (2) in the bow longitudinal direction and having a U-shaped sliding part (4), which projects from the hinge part (1) in the displacement direction and engages in a housing recess (3), and which receives a coiled spring (14) between its two legs (6), whose hinge-side end is supported on a buttress (13) belonging to the housing (2) and whose diametrically opposite end is supported on the web (5) connecting the two legs (6) of the U-shaped sliding part (4), the hinge part (1) having the sliding part (4) comprising a passage opening (16) running in the longitudinal direction of the coiled spring (14). In order to achieve advantageous construction conditions, it is suggested that the buttress (13) be screwed through the passage opening (16) of the hinge part (1) running coaxially to the coiled spring (14) into a female thread (11) of the housing (2) which is coaxial to the coiled spring (14).
