Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for decorating sanitary equipment, which is suitable as a method for decorating a faucet device having a surface plated.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
The faucet device is constructed by first nickel-plating the surface of the bronze main body and then chromium-plating the upper surface of the main body, so that there is a problem that the surface is greatly restricted in decoration.

The decorating method includes a method of hitting a metal mold on the surface to form a concave portion on a surface and forming an uneven pattern on the surface, and a laser processing on the surface to form a concave portion on the processed surface to form an uneven pattern on the surface. A method for forming the layer is known.

However, in the case of the decorating method, a dedicated mold must first be manufactured and prepared for decorating,
There is a problem that decoration requires a great deal of labor, time, and cost.

In the latter case of the decoration method by laser processing, programming for controlling the traveling of the laser must be performed according to the pattern to be formed,
Similarly, there is a problem that decoration takes a lot of time and labor. In addition, these methods form an uneven pattern, and thus have a problem that coloring cannot be performed.

As a method of coloring the surface of the faucet device, it is possible to form a colored pattern with an ink jet or the like, but in this case, the colored pattern on the surface is relatively easy when the faucet device is washed. There is a problem of peeling off. The decoration of the faucet device has been described above as an example, but the same problem occurs in other sanitary equipment devices having a metal layer on the surface.

[0007]

The method for decorating housing equipment of the present invention has been devised to solve such a problem. According to the first aspect of the present invention, when at least the surface of the sanitary equipment having a metal layer on its surface is decorated, the surface of the metal layer is blasted with a masking material attached. By denting the portion of the surface of the metal layer other than the portion covered with the masking material, or blasting the surface of the body with the masking material attached to the surface of the body before forming the metal layer. Is performed to form a concave-convex pattern on the surface of the main body by forming the metal layer on the main body surface after recessing the portion other than the portion covered with the masking material.

A second aspect of the present invention is characterized in that, in the first aspect, the sanitary facility equipment is an accessory equipment.

According to a third aspect of the present invention, the surface of the faucet device as the sanitary facility device according to the first aspect, wherein the main body surface is nickel-plated and the upper side thereof is chromium-plated as the metal layer, is decorated. Prior to forming the plating, the plating surface is blasted while the masking material is adhered to the plating surface, and the portion of the plating surface other than the portion covered with the masking material is depressed. Blasting the body surface with the masking material attached to the body surface, and forming the plating on the body surface after recessing the portion of the body surface other than the surface covered with the masking material. The feature is that an uneven pattern is formed on the surface.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the masking material forms a sheet having a predetermined pattern of hollows, and hard particles are passed through the hollows to form the hard particles on the surface of the metal layer or It is characterized by colliding with the surface of the main body to form an uneven pattern on the surface.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the blasting process is performed in a state where the coloring material is adhered to the surface of the hard particles to form an uneven pattern and to perform coloring at the same time. Characterize.

[0012]

As described above, according to the decorating method of the present invention, blasting is performed in the state where the masking material is attached to the surface of the metal layer, or the masking material is applied to the surface of the main body before the metal layer is formed. By applying a blasting process in a state of being attached to form a metal layer after that, an uneven pattern is formed on the surface.According to the present invention, the uneven pattern is formed on sanitary equipment having a metal layer on the surface very easily. A decorative pattern made of can be applied.

Further, according to the present invention, various concave and convex patterns can be easily formed in accordance with the shape of the masking material, and the masking material and the blasting process are low in cost, so that the decorative pattern can be made inexpensive and short. Can be easily applied in time.

Further, since the shape of the masking material only needs to be changed when changing the pattern, this can be easily performed when changing the pattern. In addition, in the present invention, it is possible to form a concavo-convex pattern by performing a blasting process after forming the metal layer, or to perform a blasting process on the main body surface before forming the metal layer to make a predetermined portion of the main body surface concave After that, the metal layer may be formed on the surface of the main body. In this case, by recessing the metal layer that is formed later along the recessed portion of the main body, it is possible to form a predetermined uneven pattern on the surface of the metal layer without directly blasting the surface.

The present invention provides articles attached to a sanitary room, such as toilet paper holders, towel racks, handrails, shelves, soap cases, various hooks, article boxes, operation panels such as switch panels, and other accessories. It can be applied to a device to form a predetermined uneven pattern on the surface thereof (claim 2).

INDUSTRIAL APPLICABILITY The present invention is suitable as a decorating method for a faucet device which has been particularly difficult to decorate, that is, a faucet device in which the main body surface is nickel-plated and the upper side thereof is chromium-plated ( Claim 3). In this case,
After nickel plating and chrome plating on the surface of the main body in advance, a masking material may be attached to the surface of the plating and blasting may be applied to form an uneven pattern, or the body may be first blasted to form an uneven surface. It is also possible to form a pattern and then to apply nickel plating and chrome plating to the surface of the main body to form an uneven pattern on the surface.

Particularly in the former case, that is, when nickel plating and chrome plating are first applied to the surface and then blasting is performed on the surface, hard particles such as shots vigorously hit the surface and the surface plating is peeled off. It is possible that it will end up.

However, when the present inventor actually carried out this decorating method, it was found that such plating peeling did not occur. More specifically, when hard particles such as shots hit a portion not covered with a masking material, the plating layer is simply pushed in without causing peeling, and the metal color of the plating is retained as it is. found.

In particular, when nickel plating is applied to the lower side of the chrome plating as in a faucet device, the nickel plating layer is soft, so the chrome plating layer is pushed in by blasting and the chrome plating layer is peeled off. It is thought that it will not occur. Incidentally, when the chromium plating on the surface is peeled off, the color of the nickel plating layer below it appears outside, but such a phenomenon did not occur.

As described above, in the faucet device, the body on the lower side of the plating is usually made of bronze, and when such a body is blasted to form an uneven pattern and then plated. However, the plating is formed in a concave shape along the concave portion of the main body. Therefore, this method can also form a predetermined uneven pattern on the surface of the faucet device.

The main body of the faucet device can be made of resin, and even when plating is formed on the surface of the faucet device, a predetermined uneven pattern is formed on the surface of the faucet device by blasting from the plated surface. It is possible to form. That is, the present invention is applicable not only when the main body is made of bronze but also when it is made of resin, and it is possible to form a desired uneven pattern on the surface of the faucet device by blasting.

In the present invention, a sheet having a predetermined pattern of cutouts is used as a masking material, and hard particles such as shots can be applied to the surface of an object through the cutouts to form an uneven pattern. 4).
In this case, a rubber sheet can be preferably used as the masking material sheet.

In the present invention, a coloring material is adhered to the surface of the hard particles, and the hard particles are applied to the surface of the object in that state to perform blasting, thereby forming an uneven pattern and coloring at the same time. Yes (Claim 5). In this case, since the coloring material is strongly pressed against the object surface by the collision of the hard particles with respect to the object, the adhesion of the coloring material to the object surface is strong, and even when the faucet device is repeatedly washed, etc. The advantage is that the coloring does not come off.

[0024]

Embodiments of the present invention will now be described in detail with reference to the drawings. In FIG. 1, 10 is a faucet device, 12 is its main part, 14 is a crank leg, 16 is a water discharge pipe extending from the main part 12, and 18 is a switching handle for performing switching of water discharge and water discharge stopping operation. Reference numeral 20 denotes a temperature control handle for controlling the temperature. In this example, as shown in FIG. 1 (B), the surface of the faucet device 10 (specifically, the surface of the main portion 12) has a predetermined uneven pattern (flower pattern and petals in this example) 2
2 is formed.

In the present example, the main portion 12 has a body 24 made of bronze, and the surface of the body 24 is plated with metal 26. Here, the plating 26 is composed of a lower nickel plating 28 and an upper chromium plating 30. In this example, the concavo-convex pattern 22 is formed by shot blasting the surface of the plating 26 using a masking material.

FIG. 2 shows the masking material used at that time. As shown in FIG. 2, the masking material 32 is made of a rubber sheet, and a hollow portion 22A corresponding to the concave-convex pattern 22 is formed at a predetermined position in a predetermined pattern. In this example, the masking material 32 made of this rubber sheet is attached to the surface of the main portion 12 of the faucet device 10, and shot blasting is performed in that state.

The shots (hard particles) ejected at this time do not hit the surface of the main portion 12 in the portion covered with the masking material 32, and are urged to the surface of the main portion 12 only in the hollow portion 22A. Collide well. As a result, only the portion corresponding to the hollowed-out portion 22A on the surface of the main portion 12 partially becomes the recessed portion 21, and the uneven pattern 22 is formed on the surface of the main portion 12.

At this time, the plating 26 applied to the surface of the main portion 12 is not pushed off at all and is simply pushed into the main body 24 side. Therefore, by applying such a blasting process, the plating is removed and corrosion resistance is improved. There is no problem of damage.

In the partially enlarged view of FIG. 1B, the plating 2
Although 6 is shown in a partially recessed form, it is conceivable that the degree of the recess differs depending on the conditions of shot blasting. For example, in the partially enlarged view of FIG.
Although the main body 24 is not depressed at all in the first portion, the present invention also includes the case where the main body 24 is partially depressed due to the pushing of the plating 26.

As described above, according to this example, the plating 2 is formed on the surface.
It is possible to very easily apply the decorative pattern made of the uneven pattern 22 to the faucet device 10 having the 6-shaped structure. Further, according to this example, it is possible to easily form various concave-convex patterns 22 according to the shape of the masking material 32, and the masking material 32 and the blasting process require a low cost, so that the decorative pattern can be inexpensive. And it can be easily applied in a short time. Also, when changing the pattern, simply use the masking material 3
Since it is only necessary to change the shape of 2, it is possible to easily change the pattern.

In this example, the above-mentioned uneven pattern 22 can be formed by performing blasting after forming the plating 26. In addition, the surface of the main body 24 is blasted before forming the plating 26, and then the blasting is performed. It is also possible to form a predetermined uneven pattern 22 on the surface by forming the plating 26 on the surface of the main body 24.

In the present invention, as shown in FIG. 2 (B), the coloring material 36 is attached to the surface of the hard particles 34 such as shots, and blasting is performed in this state to form an uneven pattern on the surface. It is also possible to apply the coloring material 36 to the concave portion 21 at the same time when the concave portion 21 is formed, and thus to color the concave and convex pattern 22 at the same time. In this case, the coloring material 3
6 is a water faucet device 10 when the hard particles 34 are strongly hit.
It adheres to the surface with a strong adhesive force and does not come off easily.

Further, in this example, even when the main body 24 is made of resin, it is possible to form the uneven pattern 22 by plating the surface of the main body 24 and then blasting as described above. It is possible.

FIG. 3 shows another embodiment of the present invention, which is an example in which the present invention is applied to the toilet paper holder 38. In this example, the concavo-convex pattern 22 is formed on the surface of the stainless paper cutting plate 40 in the toilet paper holder 38. The same method as described above can be used when forming the uneven pattern 22. That is, a masking material 32 made of a rubber sheet or the like having a hollowed portion corresponding to the uneven pattern 22 is pasted, and shot blasting is performed in that state to form the uneven pattern 22 on the surface of the paper cutting board 40. be able to.

Although the embodiment of the present invention has been described in detail above, this is merely an example. For example, the above-exemplified article is merely an example of the object article of the present invention, and the present invention can be applied when forming a concavo-convex pattern on other various articles, etc. within the scope of the present invention. It can be implemented in a mode in which various changes are added.
