[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a soft sword used for training or a game of self-defense kendo (commonly known as sports chambara).

[0002]

2. Description of the Related Art Self-defense kendo, which uses soft swords such as soft swords and soft long swords having a soft cushioning property, to protect itself from attack by an opponent, is widely known as a so-called "sports champala". It should be noted that the sports chamber is introduced in the title "Sports Chambera's Recommendation" (by Tetsuto Tanabe, published by Sobunsha).

FIG. 3 is a sectional view of a soft long sword K, which is one of the soft swords used in this self-defense kendo, disclosed by the applicant in Japanese Utility Model Application No. 3-695.

In FIG. 1, reference numeral 1 denotes a handle having a circular cross section provided with a flange portion 1a, and reference numeral 2 denotes a first cylindrical core made of a flexible plastic, which is inserted into a hole 1b of the handle 1 to form a peg. By being stopped at the same, it is coaxially attached to the same pattern portion 1. Reference numeral 3 denotes a plastic second cylindrical core, which is inserted into the first core 2 and attached to the same via a coil spring 4. That is, one end of the coil spring 4 is fixed to the first core 2 with an eye nail,
The other end is inserted into the end of the second core 3 and is fixed with an eye nail.

[0005] Reference numeral 5 denotes a dumpling portion attached to the tip of the second core 3. The dandelion part 5 includes a cylindrical soft core 6 made of sponge fitted to the tip of the core 3, a cylindrical soft core 7 made of sponge put on the tip in a cap shape, and both soft cores 6. 7, and an adhesive tape 9 wrapped around the core 3 from above the open end of the leather bag 8.

Reference numeral 10 denotes a sponge cylindrical soft core in which the protein portion 5 and the first and second cores 2 and 3 are inserted and coaxially covered with the three members 5, 2, and 3. In this embodiment, the outer diameter of the dandelion portion 5 and the inner diameter of the cylindrical soft core 10 are substantially the same. Therefore, a gap 11 is formed between the first and second cores 2 and 3 and the soft core 10.

[0007] 12 is a dandelion part 5 and a cylindrical soft core 10
It is a cylindrical soft core made of sponge and placed on the tip of a cap. Reference numeral 13 denotes a leather bag that covers the soft cores 10 and 12, and 14 denotes a grip tape wound around the handle 1 from above the open end of the leather bag 13.

The length of the handle 1 is 20 to 22 cm, the diameter is 2 to 3 cm, and the length of the cylindrical soft core 10 is 70 to 75 c.
m, the diameter is generally 4.5 to 5.0 cm, the length of the cylindrical soft core 12 is generally 4.5 to 5.0 cm, and the diameter is generally 4.5 to 5.0 cm.

Next, the operation based on the above configuration will be described.

(1) Since the dandelion 5 has elasticity and softness, the dandelion 5 has a cylindrical shape and a circular shape even when a strong impact is applied to the soft dagger K by hitting and pushing. There is no danger of breaking through both the columnar soft cores 10 and 12.

(2) Columnar soft core 12 and Dandelion part 5
Can effectively alleviate the impact force given to the opponent by the “push” of the soft long sword K.

(3) The gap 11 between the first and second middle cores 2 and 3 and the cylindrical soft core 10 is formed by elasticity of the cylindrical soft core 10 due to an impact force when the opponent is hit with the soft long sword K. Since the deformation is absorbed, the impact force applied to the partner can be effectively reduced in combination with the cylindrical soft core 10.

(4) The coil spring 4 can more effectively absorb and mitigate the impact force given to the opponent by the “push” of the soft long sword K in combination with the dampening portion 5.

[0014]

[Problem to be solved by the invention] Conventional soft dagger K
Although it has the above-mentioned excellent functions, it still has the following problems.

(1) Since one end of the coil spring 4 is fixed to the first core 2 with an eye nail, the soft dagger K
Is compressed and shrunk by the action of the strong “push”
It can no longer move to the handle 1 side. For this reason, the opponent may be damaged or feel pain by the impact force of the “push” that cannot be absorbed by the coil spring 4.

(2) The impact force received by the opponent due to “hit” or “push” cannot be arbitrarily varied.

The present invention has been made in order to solve such a conventional problem, and it is possible to sufficiently reduce the impact force applied to the opponent by the “push”, and therefore, there is no danger of damaging the opponent. , And a soft sword for self-defense kendo that does not make the opponent feel pain, "hit" and "push"
It is an object of the present invention to provide a self-defense kendo soft sword capable of arbitrarily changing the impact force received by the opponent.

[0018]

(1) A soft sword for self-defense kendo provided by the present invention comprises a handle, a first cylindrical core having flexibility attached coaxially to the handle, and A flexible rod-shaped second core inserted slidably into the first cylindrical core, an elastic soft spring portion attached to the tip of the second core, and a first core. An annular rubber that is inserted into the hole provided and the hole provided in the second core and attached to the first core;
A soft tubular soft core having elasticity, in which a dandelion part, a first core and a second core are inserted, and a gap is provided between at least the two cores to cover the three members coaxially; A bag and a soft columnar soft core having elasticity to be the core material of the toe portion are arranged at the tip of the portion and the cylindrical soft core, and the bag is covered from both soft cores to the handle, and the handle is placed on the bag. (Hereinafter referred to as a first soft sword).

(2) Another self-defense kendo soft sword provided by the present invention uses a bag made of rubber or the like which can be filled with air as the bag (hereinafter referred to as a second bag). Soft sword).

[0020]

(1) The second core of the first soft sword, to which the dandelion portion is attached, retreats and sinks into the first soft sword due to the strong "push" of the soft sword against the opponent. The impact force given by the “push” to the other party at that time is absorbed by the elastic expansion of the annular rubber. The elongation of the annular rubber can be sufficiently ensured by using a rubber material having sufficient elasticity. Therefore,
If the annular rubber of such a material is used, the second core retreats almost infinitely, and there is no danger that the second core cannot retreat by a certain amount or more unlike the conventional case. For this reason,
The impact force of the "push" hardly damages the opponent or feels pain.

(2) In the second soft sword, the impact force given to the opponent by the action of "hitting" and "thrusting" is arbitrarily adjusted by controlling the amount of air put in the bag and adjusting the internal pressure. can do.
