Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a patterning method for forming delicate and beautiful patterns on the surface of small accessories such as buttons, brooches, buckles, etc.

(Prior Art) Traditionally, in order to obtain small decorative items with a three-dimensional pattern on the surface, resin molding is performed using a mold with a pattern engraved on the mold surface, or the surface of the decorative item is molded using a router, etc. The method of engraving using a cutting tool is widely adopted.

(Problems to be Solved by the Invention) However, according to the former method, even if mass production is possible, it is difficult to provide a delicate pattern. Since the brightness, smoothness, etc. are exactly the same, there is a problem that there is little variation and the pattern becomes unclear.

On the other hand, according to the latter method, chips and scratches occur during cutting of the outline of the pattern, which significantly lowers the product value, and the pattern becomes unclear like the above method, and it is not suitable for mass production. Has a point.

The present invention has been made in view of these problems, and it is possible to efficiently produce a large quantity of beautiful small ornaments in which the patterned and non-patterned areas on the surface are clearly visible and the three-dimensional effect is excellent. The present invention provides a method.

(Means for Solving the Problems) The method for patterning small ornaments of the present invention first includes:
A large number of small ornaments can be fitted onto the surface using elastic materials.
A holding base plate 1 having fitting support holes 2 for support is formed in advance.

Next, in each fitting support hole 2 of this holding base plate 1,
A small ornament 3 such as a button having upper and lower layers 7, 8 of different colors on the surface layer is inserted and held.

On the other hand, a film 4 is prepared by forming a patterned portion 5 and a non-patterned portion 6 in a portion that matches each mating item 2, one of which is weak, and this film 4 is attached to the holding base plate. A pattern part 5 is placed on the surface of a small ornament 3 which is adhered to one surface and supported in a fitting support hole 2.

Next, a blast process is applied to the surface of the film to destroy the weak parts of the film 4, and blasting is applied to the surface of the small ornament 3 to remove the upper layer 7 that matches the patterned or non-patterned parts of the weak parts. However, the lower layer 8 is exposed.

(Function) The small decorative item 3 is firmly held in the fitting support hole 2 of the elastic holding base plate 1, and the blasting process is performed accurately on the predetermined location on the surface of the small decorative item 3 without any movement during blasting. In addition, this blasting process forms a three-dimensional pattern on the surface of the small decorative item 3 with upper and lower layers of different colors.
The engraving depth is adjusted by changing the thickness of the weakened part and the blasting time.

(Description of Embodiments) Embodiments of the present invention will be explained with reference to the drawings.
is a holding base plate made of an elastic material such as rubber, synthetic rubber, or flexible synthetic resin material, and on its surface, fitting support holes 2 having the same shape as the buttons 3 are provided at predetermined intervals vertically and horizontally. be.

The button 3 to be fitted into the fitting support hole 2 is not only made of hard synthetic resin such as urea resin, but also made of glass, wood, metal, or natural shellfish. , a relatively thick lower layer 8 and an upper layer 7 having a different color from the lower layer 8 are provided on the lower layer 8 .

These upper and lower layers 7 and 8 may be formed by applying gold plating on a relatively thick silver plating layer, or by providing a paint layer of a different color from the paint layer on a relatively thick paint layer. Furthermore, upper and lower layers of different colors may be formed by other means.

Reference numeral 4 denotes a resin film as a masking material, on the surface of which patterned portions 5 are formed vertically and horizontally at the same intervals as the button fitting support holes 2 provided in the holding base plate 1. The portion is formed as a non-patterned portion 6 which is thinner than the patterned portion 5. That is, the patterned portion 5 has the same thickness as the film 4, and the non-patterned portion 6 is formed with an extremely thin portion of the film 4 remaining. Further, an adhesive 9 is layered on the surface of the patterned portion 5 and the peripheral surface of the film 4.

Note that such a masking material may have a structure in which a patterned portion 5 that is difficult to destroy by blasting is layered on a thin film that is easily destroyed by blasting.

In order to form a pattern on the surface of the button 3 using the holding base plate 1 and the resin film 4 formed in this way, first, the button 3 is inserted into each fitting support hole 2 of the holding base plate 1.
is fitted with its surface exposed, and is firmly held by the elasticity of the holding base plate 1.

Next, the film 4 is held on the front side by the base plate 1.
The film 4 is coated on the surface of the holding base plate 1 so that the patterned portion 5 of the film 4 is superimposed on the surface of the button 3 fitted into each fitting support hole 2 and brought into close contact with the surface. After that, an abrasive material such as sand powder or iron powder is sprayed from above the film 4, that is, a blasting process is performed.
When this is done, the non-patterned part 6, which is a thin and weak part of the film 4, is destroyed by the blast a, and as shown in FIG. Only the pattern portion 5 remains without being removed.

The upper layer 7 of the button 3 corresponding to the non-patterned area is engraved and removed by the blast a, and the lower layer 8 is exposed on the surface, while the thick patterned area of the film 4 is blasted directly onto the button surface through the through hole 10. The upper layer 7 of the button 3 corresponding to 5 is not blasted,
It remains as is.

The depth of the recess 11 that is carved until the lower layer 8 is exposed on the button surface can be adjusted by changing the thickness of the non-patterned part 6 of the film 4 and the blasting time.

In this way, the button 3, which has the upper layer 7 with the convex pattern 12 on the surface and the concave portion 11 of a different color around it, is removed from each fitting support hole 2 of the holding base plate 1 and is The attached pattern portion 5 of the film 4 is removed to form a product.

In the above embodiments, a method of patterning the surface of the button 3 has been described, but the present invention is not limited to this, and can be applied to surface patterning of other small accessories such as brooches and buckles. Of course, it can also be applied to

Further, in the film 4, the patterned portion 5 is formed thick and the non-patterned portion 6 is formed thin, but conversely, the patterned portion 5 may be formed thin and the non-patterned portion 6 thick.

(Effects of the Invention) As described above, according to the method for patterning small ornaments of the present invention, first, a holding base plate made of an elastic material and having a plurality of fitting support holes for fitting small ornaments formed on the surface thereof is formed. Since the small ornaments are fitted into each fitting support hole, the small ornaments are securely held in the support holes and there is no risk of movement during the subsequent blasting process. It is possible to accurately pattern a predetermined location on the surface of an ornament.

Further, upper and lower layers of different colors are provided on the surface layer of the accessory accessory, and after the accessory accessory is fitted into each of the aforementioned fitting support holes of the holding base plate, the upper and lower layers are fitted into the respective fitting support holes. A film having a patterned part and a non-patterned part, one of which is formed as a weak part, is superimposed on the holding base plate and applied to the surface of the small ornament, and then the film is blasted from above. Therefore, the weak parts of the film are destroyed by blasting, and the upper layer corresponding to the patterned part or non-patterned part having the same shape as the weak part is removed from the surface of each small decorative item, and the shape is The lower layer, which has the same shape as the upper layer, can be exposed, and the other parts remain as the upper layer and become protrusions, and the protrusions and uniquely colored recesses stand out, creating a varied three-dimensional structure. It is possible to form a pattern.

Furthermore, a desired pattern can be engraved at the same time while a large number of small ornaments are held on the holding base plate, allowing efficient mass production.
