DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulated spear, and more particularly, to a simulated spear which can be used by a beginner of martial arts for practicing or playing spears and hittings.

[0002]

2. Description of the Related Art For example, in the case of kendo, armor is generally used during training or during a game in order to prevent injuries caused by hitting or hitting a bamboo sword. Therefore, various measures have been proposed for bamboo swords in order to prevent the bamboo swords from cracking or breaking due to torsion, bending stiffness or impact (Japanese Patent Laid-Open No. Sho 5).
9-28981, JP-A-61-37180, JP-A-62-127075, JP-A-02-6
0671, JP-A-09-10371, etc.).

[0003] Recently, in Japan, the number of people who learn martial arts derived from foreign countries, for example, China, is increasing. Some of these martial arts use a spear or sword as a weapon, but due to their origin, they rarely use armor like kendo.

[0004]

Therefore, if a beginner to such a martial art practices with a spear or a sword, there is a risk of injuring the opponent, and it is difficult to use this skill unless a moderately advanced person who has mastered martial arts considerably. This was a factor that hindered the spread of such martial arts.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a simulated spear in which even a novice can perform a lance with ease.

[0006]

Accordingly, a simulated spear according to the present invention is a simulated spear mainly used for a spear,
The tip has a spear tip, the trunk has a spear tip used for hitting, and the user has a length that can be gripped by both hands at least at a shoulder width interval. The spear tip is composed of a core rod, a tubular body and a cover cylinder, and the core rod is made of a flexible material and is bent when the tip of the spear tip hits the other party. And at least a rear half of the core rod is inserted with a gap into the above-mentioned pipe body, and the pipe body has a bending amount that is broken when a spear is thrust. In addition to restricting the deflection of the core bar, the core bar and the tubular body are covered by the cover cylinder, and the cover cylinder is covered by the tip of the spear tip. Absorb the spear force of the spear and the impact of the torso to the extent that the opponent is not damaged Wherein the material is formed by that.

One of the features of the present invention is a core rod that can be bent by a spear, a tube that holds the rod to prevent breakage by the spear, and that can be hit by the body, and a cover cylinder that absorbs impact. In that the spear tip is configured with. This allows
Even if a spear is performed and the tip of the spear tip hits the opponent, the opponent has almost no impact from the spear and there is no risk of injury.

Another feature of the present invention resides in that the core rod and the tube are covered with a cover tube, and the impact at the time of hitting by the trunk of the spear tip is absorbed by the cover tube. This allows
Even if the opponent is hit with the body of the spear tip, there is almost no impact on the opponent due to the hit and there is no risk of injury. As a result, even beginners who have not mastered martial arts as well as beginners who have not mastered martial arts do not have the risk of injuring their opponents even if they spear or hit, and can work hard to master martial arts with peace of mind.

By the way, it is conceivable that the tip of the spear is composed of a core rod and a cover cylinder. However, there is a large difference in the spear thrust and the hitting force between intermediate and advanced martial arts beginners. When set according to the beginner's spear force, the impact of the spear on the opponent becomes large when used by intermediate and advanced users, and there is a risk of injury, while the bending of the core rod matches the spear force of the advanced user If set, the core bar is greatly bent and easily broken.

On the other hand, in the present invention, the amount by which the mandrel can be bent is set large, and the rear half of the mandrel is inserted into the tube with a gap therebetween and held, so that the impact caused by the spear can be absorbed. At the same time, it is possible to prevent the bending of the core rod from exceeding the bending amount by which the core rod is bent by the pipe, thereby preventing the core rod from being bent.

[0011] In order to reliably prevent the opponent from being injured by the spear, a rubber cap is preferably attached to the tip of the core rod. Further, the cover cylinder at the spear tip may be exposed as it is, but it is preferable to cover it with a cloth cover from the point of appearance.

The length of the core bar at the tip of the spear is very important.
If it is too short, it is difficult to bend, while if it is too long, it is easy to break. Therefore, the core rod needs to be long enough to bend when the tip of the spear tip hits the other party and absorb the impact force given to the other party. For this core rod, for example, a small-diameter plastic rod can be used.

In addition, the pipe body at the tip of the spear regulates the deflection of the core rod exceeding the amount of bending that occurs when the spear strikes,
An important feature is that it allows hitting with the body of the spear tip. For example, a plastic tube can be used for this tube.

Further, it is important that the cover cylinder is made of a material capable of absorbing the spear force by the tip of the spear tip and the impact force by the body to the extent that the other party is not damaged. For example, a polystyrene foam cylinder can be used. This cover cylinder may be left open at the tip end side, but it is preferable to close the cover cylinder with the same material, for example, with a lid, in order to further increase the safety against the impact of the spear.

Specifically, the core rod at the tip of the spear has a length of 700
mm small-diameter plastic rod, 420 mm long for the tube
It is preferable to use a plastic tube described above and a styrene foam tube as the cover tube.

The handle may be of any shape as long as it can support the spear tip. However, in consideration of portability, it is preferable that the handle can be separated into the handle and the spear tip. The core material of the handle may be any material, but in view of cost and lightness, it is preferable to use small-diameter wood, for example, Ramin.
The cover may be made of any material. However, when the core is made of wood, it is preferable that the wood is not stuck in the hand.

Therefore, the core member and the connecting portion fixed to the tip are covered with a heat-shrinkable synthetic resin cover.
It is preferable that a connection portion is provided at the rear end of the spear tip so that the connection of the spear tip and the connection of the handle are detachably connected to each other.

When a blow is made with the body of the spear tip, the impact is absorbed by the cover cylinder as described above, so it is difficult to confirm whether or not the blow has been made. Therefore, it is better to insert a large part of the spear tip tube into the large-diameter tube with a gap so as to emit a blow sound when hitting the spear tip body, and adopt such a structure This makes it possible to more reliably prevent the core rod from breaking. In this case, a vinyl chloride tube can be used for the large-diameter tube.
