Description

  The present invention relates to a method for manufacturing a wooden article in which a magnet is embedded.

  Many products have been proposed in which permanent magnets are embedded so that they can be attached to and detached from metal walls. For example, Patent Literature 1 proposes a shoehorn with a magnet sheet attached thereto. Patent Document 2 and Patent Document 3 propose a shoehorn in which a permanent magnet is embedded in a handle or a handle portion. Further, Patent Document 4 discloses a steak plate wooden base that can fix a steak plate using a permanent magnet embedded in a wooden stand. Patent Document 5 discloses a permanent magnet on a top plate. An embedded floor head has been proposed. In addition, as a product using the magnetic force of a permanent magnet, Patent Document 6 discloses a fitting that embeds a permanent magnet in a wooden door and detects opening and closing of the door with the permanent magnet, and Patent Document 7 embeds a permanent magnet. A dowel pot push has been proposed.

  However, in the products proposed in Patent Documents 1 to 4, since the magnet was attached to the product in a visible state, the aesthetic appearance of the product was impaired. On the other hand, in the products proposed in Patent Documents 5 and 6, a cosmetic sheet is used for blinding the magnet, and in the product proposed in Patent Document 7, a lid is attached to the recess containing the magnet. Therefore, in these products, the aesthetic appearance was rarely damaged by the magnet.

  However, even when a decorative sheet or lid is used, the texture of the decorative sheet or lid does not match that of the surrounding area, and it does not seem that the sense of incongruity occurs or the beauty of the wood grain of the wood is fully utilized. It was.

  The problem to be solved by the present invention is to provide a wooden article that is processed so as not to know that permanent magnets are buried, utilizing the grain of natural wood.

  The manufacturing method according to the present invention includes a step of obtaining a composite material in which a plurality of lumbered wood faces are overlapped with the grain direction being coincident, and a magnet is embedded therein, and the magnet is not exposed from the composite material. A method of manufacturing a wooden article in which a magnet having a step of processing into a desired shape is embedded.

  According to the present invention, there is provided a wooden article in which the wood grain used as a raw material is utilized as it is and the magnet is not apparently embedded.

FIG. 1 is a process diagram showing an example of a manufacturing method according to the present invention. FIG. 2 is a diagram showing a part of a process diagram which is another example of the manufacturing method according to the present invention. FIG. 3 is a perspective view showing an example of a wooden article (semi-finished product) obtained by the manufacturing method according to the present invention.

  The manufacturing method according to the present invention is a method for manufacturing a wooden article in which magnets are embedded, and a composite material in which magnets are embedded is obtained by superimposing a plurality of lumber grain surfaces with matching grain directions. And a step of processing the synthetic material into a desired shape without exposing the magnet.

  In short, the method of the present invention is a method of processing a synthetic material obtained by embedding a magnet into a desired shape. The term “sawmill” generally means a square or board processed from raw wood, but in this specification, in addition to them, a concept including a material with bark in a state before processing into a square and a board. Used in The term “synthetic material” means wood (such as square, plate, or bar) obtained by bonding a plurality of lumbers.

  The magnet used in the present invention is a permanent magnet. The strength of the magnetic force and the size of the magnet can be appropriately selected depending on the purpose of use. Also, a particulate permanent magnet, a permanent magnet covered with a waterproof sheet, a permanent magnet coated with a rust preventive agent, or the like can be used. The number of magnets is not limited to one and may be two or more.

  The magnet is buried in a synthetic material obtained by overlapping a plurality of lumbers. The number of lumber used for a synthetic material should just be plural, and is decided suitably. The magnet is buried so as not to be exposed on the surface of the synthetic material. For example, a hole is provided in one or a plurality of lumbers used for the production of the synthetic material, and a magnet is embedded by placing another magnet on the exposed surface of the magnet after a hole is fitted in the hole. The magnet is not buried in the annual ring surface (the surface in which the annual ring pattern appears in a ring shape), but is buried in the grain surface. The grain surface may be a regular surface or a plate surface. From the viewpoint of fixing the obtained wooden article to a wall or the like, it is preferable to embed a magnet so that it does not move inside the synthetic material. However, depending on the use of the wooden article, it may be embedded so as to move inside the synthetic material. The place to be filled is also set appropriately and can be filled not only in one place but also in multiple places.

  The plurality of lumbers are superposed on each other by matching the grain directions of the lumbers. This is because, when the grain directions are made to coincide with each other and the grain surfaces are overlapped, it becomes difficult to understand the stitches when the wooden product is viewed. The plurality of lumbers to be overlapped are preferably lumbers obtained from one raw wood. That is, it is preferable to use a plurality of lumbers obtained by dividing one raw wood in the grain direction. Here, the term “raw wood” means lumber, which is a raw material, used to obtain a lumber to be bonded. The lumber to be a raw wood is used in a concept including not only a square or a plate processed from the raw wood as described above but also a raw material with a bark in a state before being processed into these. The division is performed so that the grain surface appears on the division plane (cut plane) and can be almost restored to the original raw wood. For example, the square bar may be cut in parallel with the grain direction, or the square bar may be cut into blocks. This is because by superimposing the obtained lumber so as to become the original raw wood, an impression as if processed from one raw wood is given. In addition, a plurality of lumbers obtained from a plurality of raw timbers may be superposed. This is because by superimposing lumber obtained from different raw timbers, it is possible to give an accent (difference in grain or color) to the obtained wooden product.

  Next, the synthetic material in which the magnet is embedded is processed to obtain a target article. As long as the embedded magnet is not exposed, there is no particular limitation on the processing method, so-called machining, that is, processing the synthetic material into a desired shape using various processing tools such as saws, saws, and planers. After processing into a desired shape, coloring or varnishing is performed as necessary. In addition, in coloring, lumber previously colored may be superposed. Further, in the processing, it is desirable that the synthetic material obtained by returning the lumber cut out in a block shape to the shape of the original raw material wood is cut out so as not to include a seam crossing the grain. This is because a seam that crosses the grain appears in the product, and the trace of pasting the wood together is conspicuous.

  The article obtained by the present invention can be not only a finished product but also a so-called semi-finished product used for a part of the finished product. The type of the finished product or semi-finished product is not particularly limited, and the finished product may be, for example, a shoehorn, a ruler, a shiatsu tool, a steak plate, or an ornament. In addition, the semi-finished product is, for example, a grip part of a key ring, and can be a part such as a handle of a cutlery such as a spoon or fork or a handle of a kitchen knife.

  According to the method according to the present invention, since it is processed from a synthetic material obtained by laminating wood surfaces, it is possible to obtain a wooden article that hardly shows the joints of lumber in appearance. As a result, a wooden article that can be magnetically attached to a wall or the like without providing the presence of a magnet is provided.

  Next, the present invention will be described based on the following examples, but it goes without saying that the present invention is not limited to the following examples.

  FIG. 1 is a process diagram showing an example of a manufacturing method according to the present invention. FIG. 1 shows a method for manufacturing a wooden shoehorn. As shown in FIG. 1 (a), one raw timber (corner) 1 is prepared. Next, as shown in FIG. 2B, the square member 1 is divided into two in the wood grain direction to obtain the plate member 20 and the square member 10. And as shown in the figure (c), the magnet 2 is inserted in the hole 11 provided in the square 10. Then, the board | plate material 20 is bonded together in the original position, and the composite material 3 returned to the square material substantially the same as the original square material 1 as shown in FIG. Thereafter, the synthetic material 3 is processed to obtain a shoehorn as a wooden article 5 as shown in FIG.

  FIG. 2 is a diagram showing a part of a process diagram showing another example of the manufacturing method according to the present invention. The synthetic material 3 shown in FIG. 2 is produced by superimposing six lumbers (five plate members 20 and one square member 10), and three lower lumber members (two plate members 20 and one square member 10). The magnet 2 is buried in the hole 11 provided in the. These six lumbers are also produced by dividing one square bar as shown in FIG. In this way, the product can be processed from a synthetic material in which three or more lumbers are overlapped and a magnet is embedded.

  FIG. 3 is a perspective view showing an example of a semi-finished product manufactured by the manufacturing method according to the present invention. The semi-finished product is a spoon handle. Thus, it is good also as a semi-finished product (parts) like the pattern of cutlery, such as a spoon.

  According to the present invention, it is possible to provide a wooden product in which the joints of the trees cannot be distinguished by just looking at them and the magnets are not embedded therein. This results in a wooden product that tickle human curiosity.
