Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a handle of a bamboo sword for kendo, and more particularly to a handle that does not slip even when the bamboo sword is strongly driven at the moment of driving the bamboo sword.

[0002]

[Prior art]

 Bamboo swords for kendo generally have a structure in which round pieces of bamboo are vertically aligned and bundled with medium leather near the center, leather at the tip, and a leather handle at the base. It is a target.

[0003] Beginners who are not very skilled in kendo often hold the handle strongly when facing with the opponent or when striking with a bamboo sword, but the upper tier is enthusiastic when the opponent is moving. In order to be able to respond quickly, the handle is gently grasped to release the excess power of the whole body, and the moment the bamboo sword is struck, the handle is strongly squeezed so that the sword can be squeezed.

[0004] However, while the handle of the bamboo sword fits into the hand as it is used, the handle of the handle absorbs sweat and the like, making it easier to slip. I sometimes felt like running away. Therefore, the handle of the bamboo sword was rubbed with sandpaper to roughen the leather.

In addition, a bamboo sword is divided into a blade portion and a handle portion, and is made of a blade portion and bamboo. On the other hand, the handle portion is made of a synthetic resin material or wood so as to form irregularities on the handle portion. A bamboo sword has been proposed (see Japanese Utility Model Laid-Open No. 01-120897).

[0006] Further, a handle of a bamboo sword in which embossing is applied to the whole or a part of the patterned leather has been proposed (see Japanese Utility Model Registration No. 3077789).

[0007]

[Problems to be Solved by the Invention] However, the method of rubbing and roughening the leather of the handle is not only troublesome, but also causes the handle leather to be partially damaged immediately.

Further, since the handle of the bamboo sword described in Japanese Utility Model Application Laid-Open No. 01-120897 is made of synthetic resin material or wood, those who are accustomed to the leather handle feel uncomfortable in balance and touch. There was a problem that it was difficult to use.

[0009] Furthermore, in the handle of the bamboo sword described in Japanese Utility Model Registration No. 3077789, the patterned leather is embossed, so that the patterned leather feels hard and does not easily fit into the hand, and the surface of the patterned leather has irregularities. Despite this, the protruding portion remains the flat surface of the original patterned leather.When gripped with a small hand, it is less slippery than the conventional pattern, but it may still slip, so it is necessary to roughen it with sandpaper etc. was there.

[0010] In view of the above, it is an object of the present invention to provide a handle of a kendo bamboo sword that can surely prevent slipping without roughening the handle leather.

[0011]

[Problem to be solved]

 Therefore, the handle of the kendo bamboo sword according to the present invention is a leather handle that is fitted on the outer side of the above handle part of the kendo bamboo sword, which has a blade portion and a handle portion, and the entire shape is substantially cylindrical and is at least gripped. A plurality of microprojections are dispersed and fixed on the entire or part of the outer surface of the portion, and the plurality of microprojections are formed of a rubber material or a soft synthetic resin material that is slightly harder than the patterned leather. It is characterized by the following.

One of the features of the present invention is that minute projections made of rubber or soft synthetic resin, which are slightly harder than the pattern leather, are dispersed and fixed on the surface of the pattern leather.

[0013] This makes it possible for the small projections to firmly bite into the palm of the hand even if the handle is strongly grasped at the moment of the bamboo sword, without feeling uncomfortable like a synthetic resin or wooden handle. Compared to embossed patterned leather, it is less slippery and does not have the feeling of slipping out of the pattern, allowing accurate driving.

In addition, there is no trouble such as rubbing the leather of the handle to make it rough, and the desired durability can be guaranteed without the leather of the handle being partially damaged immediately.

The microprojections may be fixed to at least the outer surface of the handle leather of the grip portion, but the grip portion often differs depending on the skill and personality of kendo. Therefore, it is preferable that the plurality of minute projections be dispersed and fixed to the entire outer surface of the pattern leather.

If the microprojections are too large, the hand holding the handle will feel uncomfortable, while if they are too small, a reliable anti-slip effect cannot be obtained. According to the prototypes of the present inventors, a reliable anti-slip effect can be obtained when the plurality of microprojections are substantially conical with a height of 0.5 mm to 1.5 mm and a maximum diameter of 0.5 mm to 1.5 mm. Have confirmed.

When the distance between the microprojections is too large, a reliable anti-slip effect cannot be obtained. When the distance between the microprojections is too narrow, the palm of a hand may slide on the microprojections arranged side by side. . According to the prototypes of the present inventors, it has been confirmed that the plurality of microprojections should be dispersed at intervals of 0.5 cm to 1.5 cm between adjacent microprojections. ing.

The microprojections may be made of a material that is slightly harder than the patterned leather, but according to the prototypes of the present inventors, it is made of a rubber material or a soft synthetic resin material, for example, a soft vinyl chloride resin material. Has been confirmed to be preferable in terms of anti-slip effect, manufacturing process and manufacturing cost.

The microprojections can be fixed to the surface of the patterned leather using, for example, an appropriate adhesive, but the manufacturing operation may be complicated. Thus, a liquid sol of a rubber material or a soft synthetic resin material is applied to the pattern leather in a dispersed state by printing, for example, screen printing, and then gelled and solidified so as to be fixed to the outer surface of the pattern leather. Good to do.

The blade portion and handle portion of the bamboo sword are the same as a normal bamboo sword.

[0021]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on a specific example shown in the drawings. 1 and 2 show a preferred embodiment of the handle of the bamboo sword for kendo according to the present invention. In the figure, a bamboo sword 10 is made of a material obtained by dividing a round bamboo vertically into four pieces, and a front leather 20 is fitted on the outside of the front end portion of the material, and a middle leather piece is provided near the center of the round bamboo. 21 and the blade part 11 is composed.

The rear end of the bamboo material is a handle, and a handle 22 made of leather is fitted on the outside of the handle, and the tip leather 20, the medium leather 21 and the handle 22 are arranged in the longitudinal direction. Are tied by a string 23 extending to

The handle 22 is manufactured by sewing sheet-like leather into a cylindrical shape with a bottom. The tip side is folded and sewn with a strap to form a handle 24, and the handle 24 has a string 23. In addition, a plurality of minute projections 30 are almost uniformly distributed on the outer surface of the handle 22 and are fixed to the handle leather.

Each of the plurality of microprojections 30 is made of a soft vinyl chloride material that is slightly harder than the patterned leather, and has a height of 0.5 mm to 1.5 mm and a maximum diameter of 0.5 mm to 1.5 mm. It has a shape between the microprojections 30 and the microprojections 30 adjacent to the periphery. The spacing is 5 cm to 1.5 cm. Note that other soft synthetic resin materials and rubber materials can also be used.

When the microprojections 30 are dispersed and fixed on the outer surface of the handle 22, a plasticizer and, if necessary, a foaming agent are mixed with the soft vinyl chloride resin to form a liquid paste sol, which is then subjected to screen printing. When it is applied in the form of dots dispersed on the surface of the patterned leather of the sheet material of the pattern 22, the shape becomes substantially conical due to the characteristics of the sol. The amount of application is preferably determined in advance by experiments or the like so as to obtain a conical amount having the above-mentioned dimensions.

Next, when the liquid paste sol applied to the pattern leather is heated to a predetermined temperature and dried, the vinyl chloride resin is entangled with the fibers on the surface of the pattern leather, and when cooled, it gels and solidifies the vinyl chloride resin. Thus, the plurality of microprojections 30 can be fixed to the surface of the patterned leather. Thereafter, the pattern leather is sewn in a cylindrical shape with a bottom in the same manner as in the prior art, and the tip is turned back and sewn with a strap to form the pattern base 24, thereby obtaining the pattern 22 of this example.

As described above, the minute projections 30 made of soft vinyl chloride resin, which is slightly harder than the pattern leather, are dispersed and fixed on the surface of the pattern leather. There is no feeling of incompatibility, even if the handle is struck firmly at the moment of bamboo sword, the small projections 30 will bite into the palm of the hand, making it less slippery than embossed pattern leather. He does not feel like slipping and escaping and can make accurate shots.

In addition, it is not necessary to rub the patterned leather with sandpaper or the like, so that the complexity can be eliminated, and the expected durability of the pattern 22 can be guaranteed by preventing the patterned leather from being damaged.
