Description

Description: TECHNICAL FIELD The present invention relates to a soft sword and a soft stick used in a sports chamberara (registered trademark) which is a kind of self-defense technique.

BACKGROUND ART In recent years, sport chamberaras, which are rapidly spreading as a new self-defense technique (swordsmanship), have been trying to eliminate the need for armor.
14 Soft sword (a), soft spear (b),
And a soft bar (c) were used.

Among these, for example, as shown in FIG. 15, a soft sword has a configuration in which urethane 28B is wound as an elastic material around a core rod 28A, and a cloth or leather bag 28C is placed on the urethane 28B. .

This soft sword was very convenient because the elasticity of urethane 28B did not hurt the opponent without armor.

However, the conventional soft sword has the following problems.

(1) Since the quality of urethane and the like varies, the performance of the soft sword naturally varies.
Playing a match could be quite unfair.

(2) Since urethane hardens during use,
It was mandatory to replace urethane on a six-month basis, but if the user continued to use the urethane without replacing it, it could cause an accident.

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a soft sword and a soft stick with uniform quality and little deterioration in performance by using gas instead of urethane as an elastic material.

To achieve this object, a soft sword provided by the present invention is described in the following (1) to (4).

It is called a soft sword. ).

Here, the relationship between the center and the thickness of the grip body is arbitrary, and the length of the center may be shorter or longer as long as it can be accommodated in the blade portion.

Further, the core and the grip body may be integrally formed of the same member, or the core may be formed of a material softer than the grip body and may be integrally fixed to the grip body.

(2) A grip body made of a hard material, an airtight bag-shaped blade made of an elastic material attached with an opening closely attached to the tip of the grip body, and the grip body A core protruding into the blade body coaxially and integrally provided, and a cylindrical outer core made of a soft material fitted around the core and attached around the core. A soft sword (hereinafter referred to as a second soft sword) formed by filling a gas and forming a cavity therein.

(3) A supply hole for supplying gas to the inside of the blade portion is provided in the grip body and the core of the first soft sword, and gas can be supplied into the blade portion in this supply hole. Soft sword equipped with a valve that can prevent leakage.

(4) A supply hole for supplying gas to the inside of the blade portion is provided in the grip body and the center of the second soft sword, and gas can be supplied into the blade portion in this supply hole. Soft sword equipped with a valve that can prevent leakage.

In addition, the soft bar provided by the present invention includes the following (5),
It is described in (6).

(5) A first soft sword provided with a female (male) screw at the end of the grip body, and a handle provided with a male (female) screw for screwing the female (male) screw into at least one end. Soft stick.

(6) A second soft sword provided with a female (male) screw at an end of the grip body, and a handle provided with a male (female) screw to be screwed into the female (male) screw at least at one end. Soft stick.

In the soft sword and the soft stick of the present invention, since the blade portion is filled with gas as described above, the gas serves as a cushion, so that even when the blade portion hits the body, it does not feel much pain. In addition, since the blade portion is provided with a central core integral with the clip portion, the blade portion has a strong waist and is hardly bent by hitting or pushing. Further, since the blade is filled with gas, there is no problem of quality variation. Furthermore, it does not cure over a long period of use, making it extremely safe.
