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.

A mold-in hinge member for injection-molded spectacle rims of plastic material, comprising
- an eyelet portion having a base section and a body section formed with a bearing aperture and
- an anchoring portion, which is adapted to be fixed in a mold used to make said rim by injection molding and to embed said anchoring portion in said rim,
- said anchoring portion having a first section, which adjoins said base section and is larger in thickness than said base section to form a first shoulder, and a second section, which adjoins said first section and is larger in thickness than said first section to form a second shoulder,
- said second section comprising an anchoring rib which extends along an edge of said anchoring portion, and is formed with said second shoulder, so as to ensure proper anchoring of the hinge member in the rims' plastic material,
- said first shoulder being adapted to constitute a sealing surface, cooperating with said base section to ensure a seal when said anchoring portion is thus fixed in said mold.
