  Next, the surface processed plate and the method for manufacturing the same according to the present invention will be described in more detail with reference to the drawings showing an example of the embodiment. For convenience, portions having the same function are denoted by the same reference numerals and description thereof is omitted.

  1 to 4, the surface-treated plate 1 includes a base 3 and a sheet 2 attached to the surface of the base 3, and a bent portion 5 is provided on a part of the base 3. 4 is a flat part.

  The material of the sheet 2 is composed of an olefin resin sheet (olefin sheet) made of chain hydrocarbons having one double bond, such as polyethylene (PE) and polypropylene (PP). The olefin sheet has a large chemical resistance and heat resistance, a good injection fluidity, a small molding shrinkage ratio, etc., so that a large stress can be obtained when it is bent.

  The said base 3 consists of a molding board (fiber board) which uses wood fiber as a raw material, what is called a medium density fiber board (MDF). Medium-density fiberboard is a board obtained by steaming and defibrating wood chips and then adding a synthetic resin as an adhesive and hot-pressing them into a plate shape. Particle boards and oriented strand boards (OSB) using wood chips as raw materials ), The segment is small and not only the surface but also the lip is smooth. The medium density fiberboard is characterized by high processability like wood, surface smoothness and durability during bending, and is homogeneous and extremely inexpensive.

  The medium density fiberboard can produce various types of MDF by combining the kind of adhesive, the resin and density of wood chips. As the main tree species constituting the medium density fiberboard, for example, a coniferous tree system or a Lauan system is used. The adhesive is water resistant using a urethane adhesive.

  The base 3 is provided with a bendable portion 5 which can be bent in a part, and the other portion is a flat portion 4 having a relatively thick wall. A lead groove 7 is provided on the entire back surface of the bent portion 5.

  In the illustrated embodiment, the portion surrounded by the lead groove 7 has a large number of sections 8 formed in a diamond lattice shape. That is, the lead groove 7 is provided with a straight line 7a having a lower left side and a straight line 7b having a lower right line provided in parallel with each other so as to be inclined with respect to the vertical axis 1a and the horizontal axis 1b of the surface processed plate 1. Thus, a large number of sections 8 are continuously formed where the groove lines 7a and 7b cross each other, whereby a decorative pattern 9 is formed. 7c shows the intersection of each groove | channel 7a, 7b. In the case of the illustrated embodiment, the sections 8 formed in a diamond lattice are alternately arranged in “3” rows and “0.5 + 2 + 0.5” rows in the bent portion 5 formed in a width of 135 mm.

  Regarding the relationship between the depth b of the lead groove 7 and the thickness a of the bent portion 5, in the illustrated embodiment, the thickness a of the bent portion 5 = about 1.5 mm and the depth b of the lead groove 7 = about 0.75 mm. And groove depth b / curved portion thickness a = 1/2. The groove width c of the lead groove 7 is about 1 mm in the embodiment. The thickness d of the flat part 4 of the base 3 is about 3 mm. The thickness e of the sheet 2 is about 0.16 mm.

  The surface processed plate 1 is manufactured as shown in FIG. First, the sheet 2 is attached to one surface of the base 3 (S1). Next, a portion to be bent on the other surface of the base 3 is excavated to form a bent portion 5 (S2). Next, the bent portion 5 is provided with the above-described lead groove 7 and the section 8 surrounded by the lead groove 7 (S3), and the decorative pattern 9 is formed and completed.

  FIG. 5 shows a case where a display box as a product 10 is manufactured using the surface-treated plate 1 according to the present invention. The product 10 is formed in a box shape, and a surface processed plate 1 according to the present invention is attached to the surface of a structural material (not shown). The bent portion 5 of the surface processed plate 1 attached to the corner portion of the structural material is bent, and the decorative pattern 9 defined and formed by the lead groove 7 provided on the back surface of the bent portion 5 is raised like a ground pattern. I can see.

  This point will be described in detail. First, when the sections 8 surrounded by the lead grooves 7 are formed in a lattice shape, the force applied to the bent portion 5 at the time of bending is regularly arranged, and irregular force is not applied to the bent portion 5, thereby preventing breakage. be able to.

  In this regard, when the groove is only in the vertical direction (vertical direction in FIG. 1), since the groove is in a direction perpendicular to the direction of the force applied to the bent portion during bending, it can be easily bent. There is a risk of breakage because the stress against this force is small. On the other hand, when the groove is only in the horizontal direction (left and right in FIG. 1), the groove is in the same direction as the direction of the force applied to the bent portion during bending, so it is difficult to bend. Resulting in. However, since the section 8 surrounded by the lead groove 7 is formed in a lattice shape in the present embodiment, the force applied to the bent portion 5 at the time of bending is applied to the decorative pattern 9, that is, the bent portion 5 in which these multiple sections 8 are formed. The whole will receive. In the decoration pattern 9, a large number of sections 8 having the same size are continuously formed in the bent portion 5, so that an external force is equally applied to the bent portion 5. Therefore, the bent portion 5 can obtain a relatively large stress during bending.

  In other words, the above is as follows. The width c of the lead groove 7 on the back surface of the bent portion 5 becomes smaller when bent, thereby dispersing the external force. On the other hand, the narrowing of the groove width c directly affects the surface of the bent portion 5. Therefore, the diamond lattice-like decorative pattern floats like a fold mountain, and looks like a ground pattern formed on the surface of the bent portion 5.

  Therefore, according to the present embodiment, a complicated decorative pattern can be easily and quickly applied even to the decoration of a corner portion which is a small area in furniture, building materials, or the like.

  The present invention is not limited to the embodiment described above. For example, since the above-described lifting mechanism works in the same way when the decorative pattern 9 is partitioned and formed, the shape and size of the decorative pattern 9 can be variously changed. For example, the shape of the decoration pattern 9 may be a perfect circle shape as shown in FIG. 6, a closed curve such as an elliptical shape as shown in FIG. 7, or other shapes. In the case of FIG.6 and FIG.7, the decoration pattern 9 is contacted through the contact of the adjacent perfect circle or ellipse. In these cases, the section 8 is formed with two types of a regular circle 8a or an ellipse 8c and irregular diamond shapes 8b and 8d. Further, as shown in FIG. 8, the decoration pattern 9 may be constituted by a lead groove 7 made of a large and small circle. In this case, three types are formed: a circular section 8e made of a great circle, a circular section 8f made of a small circle, and an irregularly shaped section 8g. When the decorative pattern 9 is composed of an array of ellipsoidal lead grooves 7, it is desirable that the directions of the ellipsoidal lead grooves 7 are alternately reversed as shown in FIG. In the case of FIG. 9, a deformed deformed diamond shape 8 d ′ is formed between the ellipsoidal lead grooves 7 contacting in the opposite direction.

  Further, as shown in FIG. 10, even if the decoration pattern 9 is formed from an array of lead grooves 7 formed in a triangular shape, the lattice pattern is only subdivided, so that the same effect as described above can be obtained.

  The lead groove 7 forming the decoration pattern 9 may be formed not only in a straight groove but also in a curved shape. FIG. 11 shows a case where the lead groove 7 is formed in a wave shape. In this case, the section 8 has an elliptical irregular wave shape 8h, a diamond-like irregular wave shape 8i, a diamond-like positive irregular wave shape 8j with the upper part extended, and a diamond-like reverse variant wave shape 8k with the lower part extended. Are formed. The wavy line of the lead groove 7 may be an irregular curve as long as the groove lines intersect.

  The lead grooves 7 are desirably provided so as not to overlap each other as described above, but may be provided so as to overlap each other.

  Various shapes can be considered for the decorative shape of the section 8 formed by the lead groove 7.

  Further, the size of the grid shape of the lead grooves is arbitrary. For example, the grid shape of the lead grooves can be set to about 5 mm, for example, and can be applied to the end face treatment of a decorative plywood used for building materials.

  Further, the bent portion 5 can be formed on the entire surface of the base. In this case, as shown in FIG. 12, the entire surface of the base can be bent into a cylindrical shape.

  For example, a urea adhesive, a melamine urea, an isocyanate adhesive, or a vinyl acetate adhesive may be used as the medium density fiberboard adhesive.

  Also, a vinyl chloride sheet can be used as the material of the sheet.

  Next, the production of the surface processed plate 1 may be as shown in FIG. First, as shown in FIG. 15, the sheet 2 is adhered to the surface of the base material 3a constituting the base 3 (S11). At this time, the thickness of the base material 3 a is the thickness a of the bent portion 5. Next, the base 3 is manufactured by sticking another base material 3b to the flat portion 4 excluding the bent portion 5 (S12). Next, a lead groove 7 and a section 8 surrounded by the lead groove 7 are provided on the back surface of the bent portion 5 (S13), and a decorative pattern 9 is formed to complete the surface processed plate 1.

  The relationship between the depth b of the lead groove 7 and the thickness a of the bent portion 5 can be changed as appropriate within a range where b / a = 1/3, 1/4, etc. can be bent. Further, regarding the thickness a of the bent portion 5, the depth b of the lead groove 7, the width c of the lead groove 7, the thickness d of the flat portion 4, and the thickness e of the sheet 2, the above numerical values are It can be changed as appropriate.

  The present invention can be used as building materials such as furniture and panels.
