DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to an eyeglass frame decorated with stained-glass patterns and a method of making the same.


BACKGROUND ART

As disclosed by JP, A, No. 60-59319, there are two known types of stained glass patterns for decoration of an eyeglass. One type comprises an eyeglass frame provided with a stepped opening, a plate with a plurality holes, colored synthetic resins fitted in the holes, and colorless transparent resin filling the opening in which the plate is previously mounted and the other type consists of a plurality of holes formed in an eyeglass frame and colored synthetic resins fitted in the holes. However, the known patterns are too flat to bring up the image of a stained glass mounted in a building, because the patterns are not set back from but are set even with the surface of the eyeglass frame.
The present invention is intended to solve the problem as described above and provide an eyeglass frame decorated with three-dimensional stained-glass patterns to bring up the image of a stained glass in a building.


DISCLOSURE OF THE INVENTION

In accordance with the invention, the eyeglass frame has outside and inside members made of synthetic resin materials and a core member made of a metal plate. The core member is formed with a plurality of holes which are filled with colored synthetic resins to display stained-glass patterns, the core member being sandwiched in between the outside and inside members. The outside member is composed of inner colorless, transparent layer and outer colored, opaque layer. The outer layer is partly removed to reveal the patterns.
In a method for making the inventive eyeglass frame, molten resins are poured into the holes of the core member and then cured. Thereafter, the core member is put between outside and inside members of which the inside member is of a single colorless, transparent layer. The outside member is of a double-layer, the inner layer being colorless and transparent, the outer layer being colored and opaque. After the outside and inside members are joined with each other by heat, a part of the outer layer, covering the holes, is removed.
The patterns are formed by the holes filled with the colored resins, bordered by the colored outer layer, and set back from the surface of the eyeglass frame. Therefore, whoever looks at the patterns through the inner transparent layer is given the image of a three-dimensional stained glass.
The inventive method needs no more than a simple step of removing a part of the outer layer, in addition to the usual steps of preparing a core member of a metal plate with a plurality of holes, filling up the holes with colored synthetic resins, putting the core member between outside and inside members of a synthetic resin material, and joining the outside and inside members as one body.


BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 is a front elevation of the eyeglass frame according to the invention;
FIG. 2 is an enlarged section taken along the line II--II of FIG. 1; and
FIGS. 3 to 7 are perspective views illustrating different steps of the method for making the eyeglass frame of FIGS. 1 and 2.


BEST MODE OF CARRYING OUT THE INVENTION

The present invention is described in detail below with reference to drawings which illustrate preferred embodiments. As seen in FIG. 1, the eyeglass frame 10 of the invention has an outside member 20 formed with an opening 23 through which stained-glass patterns appear. The stained-glass patterns are composed of a plurality of through holes 16 in a core member 12 and colored synthetic resins 18 fitted in the holes 16. The patterns stand at the bottom of the opening 23 which is set back from the outside surface of the frame. The core member 12 and the colored synthetic resins 18 have a thickness to display the patterns three-dimensional. Thus, whoever looks at the patterns is given an impression of seeing a stained glass mounted in a building.
As seen in FIG. 2 in which a cross-section of the portion decorated with the patterns of the eyeglass frame 10 is shown, the
