Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pseudo-cloisonne ornament.

[0002]

2. Description of the Related Art Conventionally, cloisonne ware has been used as an ornament such as an emblem for an automobile. Fig. 3 shows the manufacturing process of the cloisonne ware. First, as a first step, a coining process for forming a concavo-convex pattern on the surface of the copper plate 10 is performed by a forging die created in advance to process the copper plate 10 into the shape shown in FIG. Next, as a second step, trimming is performed to remove unnecessary portions (burrs) 10a around the copper plate 10, and the copper plate 10 is processed as shown in FIG. 3 (b). After trimming, the copper plate 10 is used as the third step.
A drug applying step of applying the drugs c and d to the surface of the
(C)). In the illustrated example, the drug d containing the pigment of the same color is applied to the recesses a and b having different depths, and the drug c contains the pigment of a color different from that of the drug d. Since the recesses a and b have different depths, the colors will look different when the cloisonne ware is completed.

After completion of the chemical treatment step, firing is performed as a fourth step to bake the chemicals c and d on the copper plate 10. Next, as a fifth step, the burned chemical is polished (see FIG.
(D)) Further, as the sixth step, finish firing is performed. Then, buffing is performed as a seventh step (FIG. 3E).
In the illustrated example, the copper plate 10 is exposed, and the exposed portion of the copper plate is plated as an eighth step to complete the production. In this case, since the surface smoothed by buffing is plated, only the plated portion slightly protrudes by the thickness. In addition,
The plating process is an additional process and is not always performed. If it is not performed, the surface of the ornamental product becomes flat.

The cloisonne ware that is manufactured through the above steps has a high-quality appearance and is suitable for automobile emblems, etc.,
Since there are many manufacturing processes and most of them require manual work, there is a problem that the cost is high and the finished product tends to vary. Another problem is that the weight is heavy because a copper plate is used as the base material.

Therefore, the technical problem to be solved by the present invention is to provide an ornamental product such as cloisonne ware, that is, a pseudo cloisonne ornamental product, which is light in weight, low in cost and stable in performance.

[0006]

Means for Solving the Problems and Actions / Effects In order to solve the above technical problems, the pseudo-cloisonne ornament according to the present invention is constructed as follows. That is, the pseudo-cloisonne ornament includes a base material made of a transparent plastic molded product having a recess formed on the back surface, a colored surface formed on the recess, and a display surface formed on the back surface of the base material. The display surface is characterized by having a color pattern imitating Cloisonne ware. In this configuration, as a raw material for the molded product, for example, an engineering plastic material such as PMMA (polymethylmethacrylate), PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene) resin is used, and the decorative product is used as an automobile emblem. It can have sufficient strength.

According to the above construction, the surface of the plastic molded product is smooth without finishing, so that there is no variation in the finished product as in the case of Cloisonne. In addition, the smoothness and gloss of the surface of Cloisonne ware can be almost the same as the surface of the plastic molded product. Also, a colored pattern imitating Cloisonne ware is provided on the back surface of the transparent base material, and the concave portion of the back surface on which the colored surface is formed looks like a convex portion when viewed from the front surface. For example, it is possible to obtain almost the same appearance as the above-mentioned Cloisonne ware. When the plating color is used, the recess can be formed by a paint containing a metallic pigment or can be formed by vacuum vapor deposition.

In the pseudo-cloisonne ornament of the above construction, after the plastic molding is carried out by a previously prepared mold, a display surface imitating Cloisonne ware is formed on the back surface by a method such as printing, and the recess is colored with a plating color or the like. That is, it can be manufactured in a small number of steps. Therefore, the cost can be reduced. Furthermore, since the base material is a plastic molded product, it is possible to achieve a significant weight reduction compared to Cloisonne.

Further, according to the present invention, a base material made of a transparent plastic molded product and a display surface formed on the back surface of the base material are provided, and the display surface has a color pattern imitating Cloisonne ware. Pseudo Cloisonne ornaments featuring the above are provided. With this configuration, since the recess is not formed, it differs from the appearance when part of the cloisonne ware is plated, but compared to cloisonne ware that has no plating and the surface is flat, the appearance is almost the same. can get.

Further, in this structure, the display surface can be formed by attaching the transfer foil to the base material. According to this structure, the pseudo cloisonne ornament can be manufactured very simply by two steps of plastic molding and transfer or one step of in-mold transfer molding.

Further, in each of the above-mentioned constitutions, it is preferable that the peripheral edge surface of the base material is formed as an inclined surface which is inclined inward from the back surface to the front surface. If the end surface is at a right angle to the surface, the color pattern on the back surface may look unnatural due to the refraction of light when the ornament is viewed obliquely from the front, but if the end surface is an inclined surface like this , The color pattern on the back side can be seen naturally even diagonally from the front, so the appearance is closer to that of Cloisonne ware.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
This will be described in detail with reference to FIGS. 1 and 2.

First, the first of the pseudo-cloisonne ornaments according to the present invention
The embodiment will be described with reference to the sectional view of FIG. In the figure, reference numeral 1 is a base material formed of an engineering plastic material, and a recess 1a having a size of about 0.5 mm to 1 mm in length, width and depth is formed on the back surface. This ornament is constructed as an automobile emblem, the surface of which, although not visible in the figure, is slightly curved to match the slightly curved shape of the body of the automobile. The thickness tg is the same as the thickness tg of Cloisonne ware shown in FIG.

Around the recess 1a on the back surface of the base material 1,
As a display surface of a color pattern that resembles Cloisonne ware, a dark-colored printing surface 2 corresponding to the darkly appearing part a of the decoration of Cloisonne ware 2 in FIG.
Then, the light-colored printing surface 3 corresponding to the lightly visible portion b is formed. In order to imitate Cloisonne ware using a chemical c containing a pigment of a different color, printing may be performed using an ink corresponding to that color. Then, from the top of the printing surfaces 2 and 3,
A metal surface 4 formed by vacuum-depositing a metal such as aluminum or chromium is formed as a colored surface, and a backing coating 5 is applied to enhance the color hiding property and prevent corrosion of the metal surface 4.

According to the above construction, the surface smoothness and gloss of Cloisonne ware can be almost the same as that of the surface of the plastic molded product 1, and since the base material 1 is a plastic molded product, the surface finish is finished. Does not vary. In addition, a color pattern simulating cloisonne ware is provided on the back surface of the transparent base material 1, and since the recessed portion 1a on the back surface made of metal is seen as a slight protrusion when viewed from the surface, cloisonne ware plated on the surface You can get almost the same look.

In order to manufacture the pseudo-cloisonne ornament having the above-mentioned structure, plastic molding is performed using a previously prepared mold, printing is performed on the back surface with an ink containing the same pigment as that contained in the chemicals used for Cloisonne firing, and the concave portion is further formed. After vacuum deposition on 1a,
It can be done by applying a lining coating. In this way, since this ornament can be manufactured in a small number of steps, the cost can be reduced. Note that the concave portion 1a can be formed by coating with a paint containing a metallic pigment in addition to vapor deposition when the concave portion 1a has a metallic color. Further, it is possible to form a colored surface using a coating material other than metallic material to give a three-dimensional effect different from the case of using metallic material.

Next, a second embodiment of the present invention will be described with reference to FIG. This example is different from the first embodiment in that no recess is formed on the back surface. The transparent plastic substrate 6 has a substantially flat plate shape, but the surface thereof is slightly curved in accordance with the slightly curved shape of the body of the automobile, which is not shown in the figure. Further, a display surface 7 imitating a color pattern of Cloisonne is formed on the back surface thereof, and has the same thickness tg as that of Cloisonne in FIG. The display surface 7 includes a dark color printing surface 7a and a light color printing surface 7
b, and a metallic printing surface 7c. The display surface 7 can be formed by printing on the back surface of the plastic base material 6, or can be formed by using a transfer foil having print surfaces 7a, 7b, 7c formed in advance and using the transfer foil.

According to this structure, although the metallic printing surface 7c does not appear as a slight convex portion when viewed from the surface, the overall appearance is almost the same as that of plated cloisonne ware. Further, if the printing surface 7c is formed as a printing surface of a color other than metallic, a decorative article having a flat surface and almost the same appearance as Cloisonne ware can be obtained without plating. In addition,
With the configuration shown in FIG. 2, a molded product can be extremely easily manufactured by two steps of plastic molding and printing or transfer, or one step of in-mold transfer molding.

Next, modified examples of these embodiments will be described. As shown by phantom lines in FIGS. 1 and 2, the peripheral edge surface of the substrate is angled from the back surface to the front surface by an angle h (for example, 5
It is preferable that the inclined surface is inclined inward at an angle of 15 ° to 15 °. If the end face is at a right angle to the surface, the color pattern on the back face may look unnatural due to the refraction of light when the ornament is viewed obliquely from the front. This makes it easier to see the color pattern on the back side even from diagonally forward, so you can get an appearance that is closer to cloisonne ware.
