JP2011025436A - Engraved stone material body part of which is engraved and on which pigment is spread - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide an engraved stone material body on which a pigment can be easily spread on even a line engraving with an approximately 300 μm regardless of a situation that engraving of a stone material by a laser processing has been conventionally used, and relatively deep engraving and large line engraving are applied, but it is difficult that a fine color expression is freely adopted. <P>SOLUTION: The engraved stone material body structure bringing about a rich expression is prepared by smoothly processing an optional face of the stone material, forming an unevenness along an optional pattern on the face by a laser processing, and spreading a monochrome or multi-color pigment on the recessed face. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  In the present invention, a stone or a base material is used to apply a picture or a letter and a combination thereof using a laser on any surface thereof, and a single color or a plurality of pigments are spread on the engraving portion using a special technique. A sculpture is provided.

It is well known that there are monuments and tombstones as typical examples of carving stone.
The sculpture method used to be hand-carved in the old days, and machine digging is now the mainstream due to the trend of the times.
Sculptures that do not require complicated patterns or deep digging are often performed by sandblasting or laser processing.

  In the sand blasting method, an engraving body is proposed in which a masking film having a pattern prepared in advance is attached and a necessary portion is engraved by a sand blasting method in a later process to express unevenness (Patent Document 1).

On the other hand, in laser processing, a plate has been proposed which engraves the name of a syllabary or common name with a laser and applies an adhesive on the back surface to be attached to a grave marker or the like (Patent Document 2).
Further, an antique that engraves characters, ghosts, figures, etc. on the external surface of the antique main body by laser processing has been proposed (Patent Document 3).
Furthermore, an information recording plate has been proposed in which a plate-like surface made of various ceramics is colored by heating at a high temperature (Patent Document 4).

  Both are simple sculptures, and engraved surfaces such as hand-carved, machine-digged, and sandblasted typified by tombstones may be painted with enamel, etc. Therefore, it is possible and impossible to express in detail. On the other hand, although complex patterns can be expressed by laser processing, the uneven size of the engraving is thin, and coloring has had problems in detailed expression and durability.

As mentioned above, there were sculptures in which sculpture was applied to stone and the uneven surface was colored, but it was expressed by engraving for fine work and pigment spotting, and it was free without using special pigments. There were no stone sculptures with excellent expression and durability.

Regarding claim 1, a stone material which solves the above-mentioned problem and has a single-colored or multi-colored pigment spread using a special technique on a complicated and detailed pattern with shallow irregularities of engraving by laser processing A sculpture was developed.
In this process, after the surface of the stone is processed smoothly, a masking film having a required pattern is attached, and the pattern is engraved by laser processing in which the pattern is input in advance.
Remove the masking film attached after engraving and express the pigment corresponding to the pattern by spreading and drying at room temperature using a special technique (corresponding to know-how and not disclosed in detail in this application). Provide stone sculptures.

  Regarding claim 2, by using the technology and technique of the present invention, it is proposed that various commodities such as monuments, mouse pads, award cards, tombstones, nameplates, welcome boards, signboards, etc. that simulate traffic tickets can be discharged. is there.

By using the techniques and techniques of the present invention, it is possible to spread pigments even on fine lines of about 300 microns, which have been difficult to express in the past. A sculpture that expresses a colored pattern can be discharged.
In addition, the paint used as the pigment may be a commercially available acrylic paint that is usually used. It is also advantageous in that it does not require special pigments, such as being easily compatible with multiple colors, readily available, and being water-soluble. is there.

The oblique view of the stone rocking body of Example 1 Front view of stone rocking body of Example 1 Side view example of stone rocking body of Example 1 The front view of the stone rocking body of the similar shape of Example 1 Side view of a stone rocking body of similar shape in Example 1

About Claim 1, the arbitrary surface 2 of a stone material is processed in advance smoothly, the masking film which woven the design 6, such as a character, a picture, or its combination, on the surface 2 is attached to this surface, and a laser processing machine is used. Engraving along the pattern of the masking film by utilizing it, and applying a recess to the surface.
The masking film is removed from the surface of the stone where the recesses are required, and a monochromatic or multicolor pigment (water-based paint such as an ordinary commercially available acrylic paint) is specially applied to the laser processed recesses. The stone engraving body 1 is completed by spreading by a technique and drying the spreading paint at room temperature.

The rocking body of the stone sculpture 1 using the technique of the present invention will be described with reference to FIGS.
The stone 1 has a circular outer periphery, one side (back surface) of the side surface 3 is formed into a plane having a vertical angle with the circumference, and the other (front surface) 2 is processed at an angle of 120 to 150 degrees with the circumference. (FIG. 3A), a stone engraving body 1 that restores to a fixed angle at all times with respect to left and right swinging in the circumferential direction by making the difference in material thickness between the upper part 4 and the bottom part 5 different in weight. is there.
On the surface 2 of the stone sculpture 1, a pattern 6 such as an appropriate character, painting, or combination thereof is applied by laser processing, and the smallest sculpture has a 300-micron recess formed in the recess. Color pigments are spread by special techniques.

The processing angle with respect to the circumference of the front surface 2 and the back surface 3 of the stone engraving body 1 in the present invention may be reversed as shown in FIG. 3B, or may have the same angle as shown in FIG. It is not specified if the size of the top 4 is small and the size of the bottom 5 is large.
Further, as shown in FIGS. 4 to 5, a shape in which the bottom portion 5 has an arc shape across the front surface 2 and the back surface 3 of the circumference and has a restoring force against back-and-forth swing is also included in the scope of the present invention. To do.

Also, the shape may be provided with a cavity in the circumference, and it is not necessary to maintain a circular state by partially processing the outer periphery except for the periphery of the bottom 5. It may be processed into the shape of a bird, and if the bottom 5 is kept in a circumferential shape and can be restored with respect to the swing in the circumferential direction, it is within the scope of the present invention.

Claim 2 will be described.
A memorial that imitates the tickets of various transportation systems based on stone by making use of the features of easy engraving of pigments by engraving of ultra fine lines by laser processing and the special technology and technique of the present invention in the recesses of the engraving It can be used to express colorful letters such as sculptures, mouse pads that sculpt senders and advertisements, corporate and government charter certificates, tombstones and monuments, nameplates for businesses and households, store welcome boards, and company signboards. A heavy stone sculpture 1 can be provided.
The shape of the stone sculpture 1 is not limited by the shape of the first embodiment of the present invention, and it is within the scope of the present invention to have a free shape that matches the purpose of use.
