DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for decorating eyeglass parts, and more particularly to a method for decorating a metal temple with a thermosetting resin.

[0002]

2. Description of the Related Art Conventionally, in a method of decorating a metal temple with a thermosetting resin, a method of pouring a resin into a mold having a concavo-convex pattern and fitting the resin into a through hole of the temple is often used. Had been

[0003]

However, in the above-mentioned method, a mold or the like must be separately manufactured, which is costly, and in the case of a small lot, it may be completely wasted.

In addition, it takes time and effort to take out the decorative piece from the mold and fit or attach the decorative piece to the temple.

[0005] Further, as for the concave and convex pattern, a pattern which is sharply cut out cannot be displayed.

[0006]

In the present invention, in order to solve the above-mentioned problems, first, a concave portion is provided in the temple portion, and the thermosetting resin is thickened in the concave portion. The resin is cured by drying at 60 ° C. to 100 ° C. for 1 hour to 4 hours, and characters and patterns are cut and exposed on the cured resin surface directly by a cutting machine with the resin attached to a temple. Took.

[0007] Next, a method of decorating a metal temple for eyeglasses with a thermosetting resin, wherein a through hole is provided in the temple portion, and the thermosetting resin is filled in the through hole so as to be thickened. The resin is cured by drying at 60 ° C. to 100 ° C. for 1 hour to 4 hours, and the cured resin surface is directly cut and exposed by a cutting machine with the resin attached to the temple. Was.

In order to further enhance the decorative property, the thermosetting resin is dried and cured at 60 ° C. to 100 ° C. for 1 hour to 4 hours, and then the surface to be cut is dyed with a sublimable dye. We also took the method of cutting out characters and patterns.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1, (a), (b) and (c) show the decoration process of the first embodiment, and (a) a concave portion of a metal temple 1. 2 was filled with (b) the thermosetting resin 3 so as to swell to a thick wall,
To 100 ° C. for 1 to 4 hours to cure the resin, and (c) characters and patterns 4 were cut and exposed on the cured resin surface 3 directly by a cutting machine.

The thermosetting resin is preferably an epoxy resin, an acrylic resin, or a urethane resin, and more preferably has a high viscosity.

In the cutting process, if the shape information of the concave portion of the temple, the information of the characters and patterns, the number of cuts, and the like are input in advance to the personal computer, the cuts are automatically performed, so that manual work is required. Cost is also reduced.

FIG. 2 is a process chart of the second embodiment,
(A ') Vacancy 5 of metal temple 11 having through hole 5
(B ') is filled with thermosetting resin 31 so as to swell to a large thickness, and dried and cured at 60 to 100 ° C. for 1 to 4 hours. Characters and patterns 4 with a cutting machine directly while wearing
1 was cut and exposed.

In this case, similarly to the first embodiment, since each piece of information is output from the personal computer and cutting is performed, the work can be completed at low cost without any trouble.

FIG. 3 is a cross-sectional view of the third embodiment. After curing the decorative thermosetting resin, a different color 6 is applied to the surface of the resin with a sublimable dye, and the resin is dried and cut.
In this method, a change in color or a gradation is applied, so that the design spread is also increased.

FIG. 4 is a partially cutaway perspective view of the first embodiment, in which a decorative pattern can be expressed sharply and three-dimensionally, and the number of steps required for decoration is extremely small.

FIG. 5 is a partially cutaway perspective view of the second embodiment. Since decoration can be easily performed in the same manner as described above, the cost can be reduced.

[0017]

As described above, by employing the decorating method and process of the present invention, the decorating process can be remarkably reduced, the cost can be greatly reduced, and a sharp three-dimensional decor is exhibited. I can do it.
