  The above-described conventional method for forming the appearance surface of a wooden product requires dough polishing and finish polishing, and also requires a lot of labor and cost because a pattern is drawn on a portion corresponding to the appearance surface.

  The present invention is to form the appearance surface of a wooden product such as a frame, a tray, a flower stand, a display shelf, a sewing box, an accessory box or a partition so that a pattern with irregularities and figures appears and presents a new aesthetic. The object is to realize it simply and inexpensively.

  In order to achieve the above object, according to the method of the first invention, as described in claim 1, paper, cloth, leather that is appropriately cut into a shape corresponding to an appearance surface corresponding portion of a wood molded product obtained by molding wood Affix pieces in a dotted pattern and, if necessary, in a superposed manner, and apply an intermediate coating resin to the areas corresponding to the bonded external surface of the paper, cloth, leather, etc. In addition to applying a plurality of different colors of urethane paint to the resin-coated surface, the overcoated surface of the urethane paint is properly polished, and then the polished surface is subjected to clear coating. To do.

The present invention is embodied as follows.
That is, as described in claim 2, made of paper, cloth, etc. leather piece triangle without a approximately 2 cm ² ～200Cm ² plane area, rectangular, trapezoidal, circular, various cutting waste, such as elliptical.

  In addition, as described in claim 3, various cut pieces such as paper, cloth, leather pieces, etc. are attached, or an undercoat treatment with a urethane resin is applied to a portion corresponding to the appearance surface of a wood molded product to which these various cut pieces are not attached. Apply.

  Next, according to a second aspect of the present invention, there is provided a method according to claim 4, wherein the wood molded product assembly is constructed by assembling the wood molded product at a portion corresponding to the external surface of a single wood molded product obtained by molding wood. After this, the parts corresponding to the appearance surface are subjected to an undercoating treatment with urethane resin, or various cut pieces such as paper, cloth, leather pieces, etc. that are cut into an appropriate shape in a state where they are not applied are scattered and appropriately applied. Attached in an overlapping manner so that irregularities are formed, and an intermediate coating resin is applied to the portion corresponding to the appearance surface where the irregularities are formed, and then the intermediate coating resin is applied. In addition to overcoating a plurality of different colors of urethane paints on the surface, the overcoated surface of the urethane paint is appropriately polished, and then the polished surface is subjected to clear coating.

  In this invention, as described in claim 5, a surface is coated with a cloth as a cut piece and the urethane coating is overcoated, and the surface after polishing is subjected to a plurality of different colors and irregularities. When the pattern is made to appear, the surface after polishing may be polished so that the texture of the cloth piece and the fiber texture can be seen through in addition to the outer shape of the cloth piece and the pattern on the cloth piece.

According to the present invention as described above, the following effects can be obtained.
That is,
According to the method of claim 1, the pieces of cloth appropriately cut into the shape corresponding to the appearance surface of the wood molded product obtained by molding wood are pasted in a dotted shape and, if necessary, in a superposed manner. Since it is worn, an external pattern, pattern, texture or material of various cut pieces such as paper, cloth, leather pieces, etc., is formed at the portion corresponding to the external surface. And, since the intermediate coating resin is applied to the part corresponding to the external surface where the cut pieces are stuck, the cut pieces and the fabric of the wood molded product are covered and protected by the intermediate coating resin layer, and the appearance of the wood molded product Concavities and convexities having a maximum height of several millimeters due to the thickness of the cut pieces and the thickness of the paint itself are formed at the surface corresponding portions. Then, a plurality of different colors of urethane paint are applied over the surface to which the intermediate coating resin has been applied, and then the surface of the urethane paint that has been overcoated is polished appropriately. A plurality of colors appear as dots, and the outer shape of the cut piece and the pattern on the cut piece as well as the weave and the fiber of the cloth piece can be seen through as necessary. And, since the clear is applied to the polished surface in this way, the color and pattern of the appearance surface of the wooden product are added with gloss and depth, and the appearance surface is covered with a hard layer and is hardly damaged. It will be a thing. In this way, the appearance surface of a wooden product exhibiting a new aesthetic appearance can be obtained easily and inexpensively without the need for time-consuming and labor-intensive fabric polishing or finish polishing, and without the need for drawing a pattern. It is done. This is particularly effective for effective recycling of various types of wrapping paper, used clothes, and leather products that are discarded.

According to the invention described in claim 2, the same effect as that of the invention described in claim 1 is obtained and the following effect is obtained, that is, a frame, a tray, a flower stand, a display shelf, a sewing box. Appropriate aesthetics appear on the exterior surface of wooden products such as small boxes and screens. For example, when the appearance surface is relatively small, a cutting pattern having a plane area of about 2 cm ² is used and a variety of patterns appear, and when the appearance surface is relatively large, the plane area is about 200 cm ^2. A well-balanced pattern will be displayed using

  Further, according to the invention described in claim 3, the same effect as that of the invention described in claim 1 or 2 is obtained and the following effect is obtained, that is, the undercoating treatment with urethane resin is performed on paper, Depending on whether it is applied on the upper side of various cut pieces such as cloth and leather pieces, or on the contrary, the appearance of the pattern appearing on the exterior surface of the wooden product will be different. The variety of aesthetics of the appearance surface of the can be increased.

  Further, according to the invention described in claim 4, the same effect as that of the invention described in claim 1 can be obtained with either a single wood molded article or a wood molded article assembly, and the primer is primed. Since the intermediate coating resin is applied once or a plurality of times on the urethane resin, the intermediate coating resin causes relatively large irregularities to appear on the outer surface.

  Furthermore, according to the invention described in claim 5, in addition to the effect of the invention described in claim 4, the following effect can be obtained, that is, the surface coated with the urethane paint is polished appropriately. Then, when a pattern with different colors and irregularities appears on the polished surface, in addition to the outer shape of the cloth piece and the pattern on the cloth piece, the weave or fiber pattern of the cloth piece is necessary if necessary. Since it can be seen through, the pattern that appears on the exterior surface of the wooden product can be made to correspond to the outer shape of the cloth piece that has been pasted first, or the cloth that has been pasted first. The texture corresponding to the piece can be remarkably expressed on the appearance surface of the wooden product, or a delicate pattern due to the texture or the fiber texture of the cloth piece previously attached can appear on the appearance surface of the wooden product.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a wood molded product assembly for a frame, which is a material used in the practice of the present invention, FIG. 2 is a view showing a piece of cloth cut into an appropriate shape, and FIG. FIG. 4 is a partial view showing a state in which a piece of cloth is attached to a portion corresponding to the external surface of the molded product assembly. FIG. 4 shows a part of the wood molded product assembly, and a piece of cloth is attached to the external surface corresponding portion. FIG. 5 is a sectional view showing a state in which urethane resin paint and ester resin paint are applied, FIG. 5 is a cross-sectional view showing a state in which urethane coating is repeatedly applied to the x1-x1 portion of the wood molded product assembly shown in FIG. Is a cross-sectional view showing a state in which urethane coating and clear are applied to the x1-x1 part of the wood molded product assembly shown in FIG. 4, and FIG. 7 shows a picture frame as a wooden product having an external surface formed by the practice of the present invention. FIG.

  First, a wood molded product obtained by molding wood is prepared. At this time, in addition to the case where a single wood molded product is prepared, for example, as shown in FIG. 1, a wood molded product assembly in which a plurality of wood molded products 1 are assembled (in the illustrated example, a frame is drawn. 2) may be prepared.

  Here, when preparing a single wood molded product, for example, a single wooden product is formed by a single wood molded product, such as a tray, and the wood molded product assembly 2 is The preparation is a case where one wooden product is formed by assembling a plurality of wood molded articles 1 such as a picture frame.

On the other hand, various kinds of patterned paper, wrapping paper, and synthetic fibers such as nylon and polyester, fabrics woven with natural materials such as cotton and silk (such as old clothes), non-woven fabrics, and other leathers (such as old leather) And cut them with scissors as appropriate, or cut them using multiple types of cutout dies with different cutout shapes, as shown in Fig. 2, in addition to polygons such as triangles and squares, A large number of pieces 3 having an arbitrary shape such as an ellipse are formed. Various packaging paper and clothes such these cut pieces to be exclusively discarded, and than like the leather is preferably used, the size of the old cutting pieces made with 2cm ² ~200cm ² approximately in plane area.

  Then, the cut pieces 3 are required to be scattered and formed with an adhesive at a portion corresponding to the appearance surface of a single wood molded product or at a location corresponding to the appearance surface 2a of the wood molded product assembly 2 as shown in FIG. Accordingly, appropriate numbers of various shapes can be attached in an overlapping state at the same or different positions as appropriate. Any adhesive may be used as long as it can strongly bond the wood and the cut piece 3 to each other. Moreover, it is preferable to affix the cutting piece 3 so as to make the presence of the joining points a1 of the plurality of wood molded products 1 inconspicuous. For example, the cutting pieces 3 are arranged and pasted so as to straddle the joining points a1 of the plurality of wood molded products 1. .

  Next, after the adhesive used for adhering the cut pieces 3 dries, it is transparent to the entire area of the appearance surface 2a or the cloth in the range where the cut pieces 3 are not attached among the appearance surface corresponding portions 2a. Apply a single urethane resin (sealer) s as an undercoat. The application of the urethane resin is performed to fill the grain (conduit of wood) of the wood molded product to form a flat surface (sealing), and thereby the grain surface is applied to the final surface 2b of the wood product shown in FIG. It will be a luxury product that does not appear.

  The application of the urethane resin s may be performed before the cutting piece 3 is attached. In this case, since the range to which the cutting piece 3 is attached is not determined, the cutting piece 3 is attached. It is necessary to apply the urethane resin s also to the cloth portion within the range.

  Next, after the urethane resin s is dried, as shown in FIG. 5, a transparent ester resin 4 is applied to the surface coated with the urethane resin s as an intermediate coating with a spray gun or the like. Concavities and convexities with a difference between the height and the minimum height (maximum height difference) of about several millimeters appear, and the state shown in FIG. 4 is obtained. In FIG. 4, 5a is a convex part and 5b is a recessed part. The application of the ester resin 4 is carried out with a relatively high viscosity of the paint. In addition, the unevenness of the painted surface due to the thickness of the overlapping positions and the number of various cutting pieces 3, the ester resin 4 Irregular irregularities are formed due to the aggregation of itself, and the ester resin 4 acts exclusively to supplement the sealing of the dough of the wood molded product. The size of the maximum height difference of the unevenness can be adjusted by changing the viscosity of the ester resin 4.

 Next, after the ester resin 4 is dried, a plurality of urethane paints 6 and 7 having different colors are applied to the surface on which the ester resin 4 is applied with a spray gun. For example, as shown in FIG. 5, first, as a lower layer coating, a golden or silver urethane paint 6 is applied, and after this is dried, a vermilion urethane paint 7 is applied again, and then the vermilion urethane paint 7 is dried. After that, black urethane paint 8 is applied as an upper layer coating. The color of the urethane paints 6, 7, and 8 at the time of this overcoating can be changed as appropriate depending on the type of wooden products and the purchaser's desire. This contributes to the accurate and smooth operation.

  Next, the dried urethane paints 6, 7, and 8 are dried, and the thickness of the urethane paints 6, 7, and 8 is varied depending on the thickness of the air sander using sand vapor of about 240 to 320. A plurality of single color ranges 9a, 9b each having a different color on the polished surface as shown in FIG. 7 by exposing the urethane paints 6, 7, 8 of different colors in a dotted pattern by polishing. , 9c and the shape 10 by the unevenness appear. Thus, the pattern appearing on the external surface 2a has a three-dimensional effect and depth as compared to the pattern drawn on the plane, and the colors of the urethane paints 6, 7, and 8 are changed steplessly.

  In this polishing, the urethane paints 6, 7, 8 can be seen on the surface so that the outer shape of the cut piece 3, the pattern shown on the cut piece 3, the weave 11 of the cut piece 3, and the fiber of the nonwoven fabric can be seen through. It is preferable to adjust the polishing amount of the overcoating part. As a result, the pattern appearing on the appearance surface corresponding portion 2a becomes a dense one that cannot be easily drawn by hand, and the pattern appearing on the appearance surface corresponding portion 2a is pasted first. It becomes a thing corresponding to the external shape of the cutting piece 3, or various colors and patterns of the cutting piece 3 pasted, and a congestion state such as the texture 11 appear. Thus, these are exclusively geometrical colors and patterns, and the irregularities formed by overlapping the appropriately sized pieces 3 have a unique engraving and texture.

Finally, as shown in FIG. 6, the transparent hard clear 12 is applied to the polished surface twice by a spray gun or the like, and as a result, the wood product shown in FIG. 7 finally obtained is obtained. Gloss is imparted to the pattern appearing on the outer appearance surface 2b of the frame, and scratches are prevented from occurring on the surface of the clear 12, and the pattern appearing on the outer appearance surface is maintained in a beautiful state indefinitely. Further, the gloss level of the appearance surface 2b is arbitrarily adjusted by adjusting the clear component. The appearance surface thus obtained can have a texture similar to that of ceramic skin colored with glaze.
In FIGS. 5 and 6, reference numeral 13 denotes a picture inserted in a frame as a wooden product.

The present invention can be modified as follows.
That is, ester resin or urethane paint is used as the paint used in the above embodiment, but lacquer paint can also be used.

  Further, the application of the urethane resin (sealer) s in the above embodiment may be omitted. In this case, the ester resin 4 is applied as an intermediate coating treatment to the appearance surface corresponding portion 2a immediately after the cut piece 3 is pasted, and the rest is performed in the same manner as described above.
