Abstract
The invention relates to a hinge joint (4) for eyeglasses, comprising a hinge tab (5) which engages between two limbs of a joint fork (6), and a hinge axis (7) arranged on a pivot arm (10) between the hinge tab (5) and the joint fork (6), wherein the pivot arm (10) can be pivoted about an inclination axis (9) perpendicular to the hinge axis (7) and can be retained in the respective pivot position by means of a latching toothing (12), the latching toothing interacting with a counter-toothing (13) of the pivot arm (10). In order to provide advantageous constructional conditions, it is proposed that the pivot arm (10) is provided in an elongated hole (11) which passes through the hinge tab (5) in the direction of the hinge axis (7), the longitudinal walls of the elongated hole forming the latching toothing (12) which is oriented radially relative to the inclination axis (9) and which interacts with the counter-toothing (13) of the pivot arm (10), and the hinge tab (5) engages between the limbs of the joint fork (5) with pivot play (14) relative to the inclination axis (9).
