  • Patent number: 4305644
    Abstract: The hinge members are intended for use in injection-molded spectacle rims of plastic material. An eyelet portion has a base section and a body section formed with a bearing aperture. An anchoring portion is adapted to be fixed in a mold used to make the rim by injection molding and to embed the anchoring portion in the rim. The anchoring portion has a first section, which adjoins the base section and is larger in axial thickness than the base section to form a first shoulder, and a second section, which adjoins the first section and is larger in axial thickness than the first section to form a second shoulder. At least part of the second section tapers toward the base section. The first shoulder is adapted to constitute a sealing surface when the anchoring portion is thus fixed in said mold.
