  Here, when manufacturing chopsticks using natural wood, it is preferable to make the grain of the natural wood appear on the surface of the chopsticks because a highly decorative chopstick can be obtained. In particular, natural wood knots are very decorative because of the variety of wood grain patterns. For example, it is conceivable to make chopsticks using koji knots.

  However, since the knot portion of natural wood is more fragile than the other portions, there is a problem that when used for chopsticks, cracking and the like are likely to occur, and it is easy to break, resulting in poor durability.

  In addition, when a chopstick is made using a cocoon, the cocoon is softer than natural wood such as oak, oak, chestnut, etc., so that there is a problem that it is not durable when used as a chopstick material.

  In view of these points, an object of the present invention is to propose a chopstick having excellent decorativeness and durability using a knot of natural wood.

  In order to solve the above problems, the chopsticks of the present invention are characterized in that a part thereof has a structure in which pieces of wood cut out from nodes of natural wood are bonded together. That is, a part of the chopsticks is a wooden shaft part, and the wooden shaft part is formed by pasting together a plurality of knot pieces cut out from knot parts of natural wood. Further, each knot is cut out so that the direction of the grain appearing on the bonding surface of each knot is different, and these are bonded.

  A beautiful knot of natural wood appears on the wooden shaft part, so that chopsticks with excellent decoration can be obtained. In addition, since a plurality of knot pieces are bonded together, it is possible to obtain a durable chopstick that hardly breaks or breaks.

  Here, the wooden shaft part manufactured from the knot can be arranged in the middle part between the tip and rear end of the chopsticks, but the part on the tip side of the chopsticks requires strength and durability, The chopsticks are formed from two parts, the front end side shaft part and the rear end side shaft part. It is desirable to form from a material with excellent durability (wood, plastic, metal, etc.).

  Further, it is desirable that the wooden shaft portion made of nodes is manufactured by fastening a pair of nodes. That is, it is desirable that the wooden shaft portion (rear end side shaft portion) has a rectangular cross section formed by bonding a pair of triangular cross-section pieces. If it does in this way, since the area of a bonding part can be enlarged, durability of the said wooden shaft part can be improved. Moreover, since the bonding position is located at the corner of the rectangular cross section, the bonding position is not conspicuous, and the appearance can be made excellent in decorativeness.

  The wooden shaft portion (rear end side shaft portion) composed of the knots of this configuration can be manufactured using the knot knots.

  In addition, it is desirable that the tip side shaft portion of the chopsticks, which requires strength and durability, be made of a natural wood material such as oak, oak, chestnut, which is harder than the cocoon.

  Furthermore, the rear end side shaft part consisting of nodes is covered with a transparent paint film such as urethane coating so that the beautiful joints appearing on the surface are not hidden, and the surface of the front end side shaft part is covered with a lacquer coating film. Therefore, it is desirable to produce a high quality.

  In the chopsticks of the present invention, the rear end side shaft portion or the like is manufactured by pasting together knot pieces cut out from knot portions of natural wood such as cocoons. Therefore, it is possible to obtain a chopstick with excellent decorativeness in which the beauty of the knots of natural wood appears on the surface. In addition, since a plurality of knot pieces are pasted together, there is no occurrence of breakage or cracking, so that a chopstick having excellent durability and high decorativeness can be obtained.

(A) is a perspective view showing one wooden chopsticks to which the present invention is applied, (b) is an exploded perspective view showing a state in which a front end side shaft portion and a rear end side shaft portion of the chopsticks are separated, and (c) is a perspective view. FIG. 4D is a cross-sectional view of the rear end side shaft portion of the chopsticks, and FIG. 4D is a cross-sectional view of the front end side shaft portion of the chopsticks. It is a disassembled perspective view of the rear-end side axial part of the chopsticks of FIG. It is explanatory drawing which shows another example of the chopsticks to which this invention is applied.

  Embodiments of chopsticks to which the present invention is applied will be described below with reference to the drawings.

  As shown in FIG. 1, a wooden chopstick 1 according to the present embodiment is an elongated straight chopstick having a rectangular cross section as a whole, and the tapered cross section gradually decreases from the rear end side toward the front end side. Is.

  The chopstick 1 has a structure in which a front end side shaft portion 2 having a length approximately 2/3 of the entire length and the remaining rear end side shaft portion 3 are connected and fixed in a coaxial state. The tip side shaft portion 2 is a portion made of a natural wood material that is harder than a cocoon such as an oak, oak, or chestnut. As shown in FIG. 1 (d), the tip side shaft portion 2 is made of a single piece of natural wood having a rectangular cross section, and the surface thereof is covered with a lacquer coating film 4.

  The rear end side shaft portion 3 is a portion manufactured from the nose portion of the heel, and as shown in FIG. 1 (c), two pieces of right-angled isosceles triangular cross-sections 5 and 6 having the same shape divided into two sections. The bonding surfaces 5 a and 6 a are bonded to each other with an adhesive 7. The surface of the rear end side shaft portion 3 is covered with a transparent coating film 8 such as urethane coating.

  Here, with reference to FIG. 2, the knot pieces 5 and 6 are cut out from different parts of the same knot part in the saddle material, or cut from different knot parts. The direction of the grain (annual ring) appearing on the bonding surfaces 5a and 6a of these knot pieces 5 and 6 is cut out so as to be different from each other in the bonded state. Accordingly, the side surfaces 5b and 5c other than the bonding surfaces 5a and 6a and the rear end surface 5d, and the grain appearing on the side surfaces 6b and 6c and the rear end surface 6d also exhibit different patterns.

  As shown in FIG. 1 (b), the front end surface 3a of the rear end side shaft portion 3 is in contact with the rear end surface 2b of the front end side shaft portion 2 through a mechanical engagement such as an adhesive and a hozo. Are connected and fixed in a coaxial state.

  In the chopsticks 1 configured as described above, the distal end side shaft portion 2 is made of a hard natural wood material, and a lacquer coating film 4 is formed on the surface thereof, so that it is excellent in strength and durability. On the other hand, the rear end side shaft portion 3 has a structure in which two knot pieces 5 and 6 cut out from the knot knot portion are bonded together, and the beauty of different knot patterns appears on the surface as they are decorated. It is an excellent part.

  Further, the rear end side shaft portion 3 is formed by bonding two knot pieces 5 and 6, so that there is no brittleness peculiar to knots. In particular, the direction of the grain of the bonding surfaces 5a and 6a is different from each other, so that no breakage or cracking occurs. In addition to this, since the two knot pieces 5 and 6 are so-called fastened, the bonded portions are located at the opposite corners of the rectangular cross section and are bonded at first glance. This is also preferable from the viewpoint of decorativeness.

(Other embodiments)
In the above embodiment, the chopsticks have a two-part configuration of the front end side shaft portion and the rear end side shaft portion. Instead, as shown in FIG. 3A, the chopsticks 10 can be divided into three parts, ie, a front end side shaft portion 11, an intermediate shaft portion 12, and a rear end side shaft portion 13. In this case, the rear end side shaft portion 13 can have a structure in which knot pieces are bonded together, and the intermediate shaft portion 12 and the front end side shaft portion 11 can be manufactured from a single piece of wood of the same type or different types. Of course, each of the shaft portions 11 to 13 can also be a portion having a structure in which nodal pieces are bonded together, and only the rear end side shaft portion 13 and the intermediate shaft portion 12 have a structure in which nodal pieces are bonded. Is also possible. Further, the chopsticks can be divided into four or more parts in the axial direction.

  In the above embodiment, the cross-sectional shape of the chopsticks is a rectangular cross section, but it is needless to say that the cross-sectional shape may be other than the rectangular cross section. For example, as shown in FIG. 3B, the cross section can be circular, and in addition, the cross section can be elliptical or polygonal.

  In the above embodiment, the rear end side shaft portion is manufactured by bonding two knot pieces, but the shaft portion can also be manufactured by bonding three or more knot pieces. For example, as shown in FIG. 3B, it is also possible to produce a wooden shaft portion having a circular cross section that becomes a part of chopsticks by bonding three knot pieces 21, 22, and 23 together.

  In the above embodiment, the tip side shaft portion is made of natural wood, but it can also be made of other materials such as plastic and metal. Moreover, although smoked knot pieces are used, knot pieces cut out from knot portions of natural wood other than koji can also be used.
