ABSTRACT:
A hinge connecting a bow (1) to a rim-side bow carrier (3) of a spectacle frame comprises is formed on said bow carrier (3) with an abutment surface, which faces the bow (1), which is formed with a pocket (7) that is open on the inside surface of the bow. The hinge bracket 5 is provided with stub pins, which constitute a pivot and are pivoted in bearing sockets (8) formed in the pocket (7). Grooves (9) extend from the bearing sockets, (8) to the inside surface of the bow and are tapered toward said bearing sockets (8) in depth or width so that the stub pins are a snap-action fit in the bearing sockets. To prevent an unintended separation of the bow from the bow carrier, the grooves extend from the bearing sockets on that side thereof which is opposite to a terminal edge (10), with which the bow engages the abutment surface (4) of the bow carrier (3) to define an open position for the bow.
