Abstract
Abstract An eyeglass frame (10) consisting of outside and inside synthetic-resin members (20, 25), a metallic-plate core member (12) sandwiched in between the outside and inside members, the core member (12) being partly formed with a plurality of holes (16) which are filled up with colored resins (18). The outside member is composed of inner, colorless, transparent and outer, colored, opaque layers (21, 22) of which the outer layer is removed partly in the form of a window through which the colored resins (18) and the holes (16) appear as stained-glass patterns.

Claim 1
Independent Claim
119 words
An eyeglass frame (10) decorated with stained-glass patterns comprising outside and inside members (20, 25) made of synthetic-resin materials and a core member (12) of a metal plate sandwiched in between said outside and inside members, said core member (12) being partly formed with a plurality of holes (16) filled up with colored, synthetic resins (18), characterized in that said outside member (20) consists of inner and outer layers (21, 22), said inner layer (21) being colorless and transparent, said outer layer (22) being colored and opaque, that said outer layer is partly removed to form an opening (23) through which stained-glass patterns formed by said holes (16) and said colored, synthetic resins (18) can be seen from outside.
