DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. 1 is a partial side view of an eyeglass frame assembled by applying the decorative temple part of the present embodiment, FIGS. 2 to 5 are manufacturing process diagrams of the decorative temple part, and FIG. 6 is a decorative temple part according to the present invention. It is a partial side view of the spectacle frame assembled by applying the modification example of the embodiment.

The decorative temple part T of the present embodiment is shown in FIG.
As shown in FIG. 1, a metal core member 1 and a metal core member 1
The eyeglass frame is composed of a synthetic resin handle member 2 covering the outer surface excluding the vicinity of the base end portion of the base member, and a metallic tubular decorative body 3 fitted to the outer peripheral portion of the handle member 2. The hinge 4 is attached to the end of the end piece 5 provided on the rim 6 on the take-out side.
Is foldably hinged via the.

As shown in FIGS. 3 and 4, the core member 1 of the decorative temple part T according to the present embodiment has a wide abutment member 11 formed at a base end thereof. A hinge piece 10 consisting of one piece to be hinged by number 4 is attached.

As shown in FIG. 2, the handle member 2 of this embodiment is formed in a substantially rod shape by an injection molding method, and has an insertion hole through which the core metal member 1 can be inserted in a longitudinal direction. 20 have been established.

As shown in FIG. 2, the cylindrical decorative body 3 of the present embodiment is formed in a substantially cylindrical shape by a lost wax method, and a plurality of square through holes are juxtaposed on the circumferential surface of the cylindrical body. Thus, a watermark pattern 30 is formed.

As shown in FIG. 2, the decorative temple part T according to the present embodiment has a metal cylindrical decorative member on the outer peripheral portion of the base end of the synthetic resin handle member 2 obtained by injection molding. The body 3 is fitted in a tight fit by utilizing the elasticity of the handle member 2, and thereafter, as shown in FIGS. 3 and 4, the handle member 2 fitted with the tubular decorative body 3. Core metal member 1 into the insertion hole 20 of
Can be easily manufactured by inserting and fixing with an adhesive if necessary (see FIG. 5).

As described above, in the decorative temple part of the present embodiment, it is only necessary to fit the metallic tubular decorative body 3 on the outer peripheral portion by utilizing the elasticity of the synthetic resin handle member 2. ,
As it is possible to easily decorate the temple parts, it is possible to reduce the strength by drilling a hole in the temple parts as usual, or to increase the manufacturing cost by performing laborious caulking work or brazing work as before. In addition, the materials of the decorative body and the temple parts are not limited due to the necessity of considering the high temperature history of the brazing operation.

Further, in the decorative temple part of the present embodiment, the surface of the pattern member 2 can be seen from the gap of the watermark pattern 30 of the tubular decorative body 3, so that a decoration with a very three-dimensional effect can be achieved. Further, various and excellent decorative patterns can be formed by a combination of the metal material of the tubular decorative body 3 and the synthetic resin material of the pattern member 2.

Further, in the decorative temple part of the present embodiment, when the metallic tubular decorative body 3 is fitted on the outer peripheral portion of the synthetic resin handle member 2, the watermark pattern of the tubular decorative body 3 is formed.
Since 30 penetrates into the outer peripheral surface of the synthetic resin handle member 2, the tubular decorative body 3 and the handle member 2 are securely fixed. There is no deviation.

When the cylindrical decorative body 3 is fitted on the outer peripheral portion of the handle member 2, if the handle member 2 is kept in a heat-flexible state,
The work of fitting the cylindrical decorative body 3 can be performed more easily, and the cylindrical decorative body 3 can be more securely fixed.

Further, as described above, in the decorative temple part of the present embodiment, after the pattern member 2 is formed by injection molding, the metal cylindrical decorative body 3 is fitted to the outer periphery of the pattern member 2. However, the present invention is not limited to this manufacturing method. The metallic tubular decorative body 3 is held in a molding die in advance, and the tubular decorative body 3 and the synthetic resin handle are formed by injection molding. By integrally molding the member 2, the handle member 2 having the insertion hole 20 in the longitudinal direction and having the cylindrical decorative body 3 fitted to a required portion of the outer peripheral portion is formed. Thereafter, the core metal member 1 may be inserted into the insertion hole 20 of the handle member 2 to manufacture a decorative temple part.

Further, in the above embodiment, only one cylindrical decorative body 3 is fitted to the base end portion of the handle member 2.
As shown in FIG. 6, it is of course possible to fit two tubular decorative bodies 3 at an intermediate portion of the outer peripheral portion of the handle member 2, and various design changes can be made in consideration of the design of the temple parts and the like. It is possible.

[0021]

As described above with reference to the embodiments, in the decorative temple part for spectacles and the method of manufacturing the same according to the present invention, a metal cylindrical decorative body is provided around the outer periphery of a synthetic resin handle member. Just by fitting, it is possible to decorate the temple part easily.Therefore, as in the past, a hole is made in the temple part to reduce the strength, and it is necessary to carry out crimping work and brazing work that is troublesome. This does not lead to an increase in manufacturing cost, nor does the limitation of the materials of the decorative body and temple parts due to the need to consider the high temperature history of the brazing operation.

Also, since the surface of the pattern member can be seen from the gap of the openwork pattern of the cylindrical decorative body, a decoration with a very three-dimensional effect can be achieved. Various and excellent decorative patterns can be formed by combining with a synthetic resin material.
