Abstract

PROBLEM TO BE SOLVED: To provide a saber which is reliable in use, safe, can be used in an international game by constructing a single body formed by specified stratified application of composite material, having an internal passage, and provided with a point and a tang which are electrically connectable to each other. SOLUTION: A blade 1 comprises a single body 2 formed by stratified application of composite material made of synthetic resin and glass fiber or other synthetic fibers. A passage 6 that can penetrate an electric wire such as a wire or a cable within an interior of the main body 2, a metallic tang and metallic point can be mounted respectively at a first end 4 and a second end 5. Even though a damage that has a shear part crossing or crossing at a right angle to a longitudinal axis 3 is caused in the blade 1, such a damage will be caused at a position near the hand, its cross-sectional area will be wide, and the damage does not hurt an opponent when a damaged point touches the opponent's jacket, because the blade 1 has flexibility.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade of a sword, and more particularly to a blade of a sword which is preferably used in a fencing competition such as a flute, saber or epe.

[0002]

2. Description of the Related Art
In this type of fencing sword, i.e., fencing sword used in competitions such as flues, sabers, or epees, all conventional equipment is integrated with a handle or handle.
And, those having a metal blade in which an electric device for detecting that the opponent's metal jacket is thrust are used.

[0003] In these conventional tools, the metal blade may be broken during the battle, and the broken blade may pierce the opponent's body, causing serious injury to the opponent's body. There is a problem.

This danger is caused when the metal blade is already in contact with the body of the opponent, that is, when the metal blade bends due to the pressing force when the opponent's jacket is pierced, the blade is damaged. Is caused.

This is more dangerous because the material of the blade of the sword is not completely uniform, and the blade of the sword is damaged along the diagonal axis of the blade, so-called flute mouthpiece damage.

The damage to the blade is an even greater problem because the skill level of the athlete is currently improved and the force with which the opponent is hit is becoming stronger. In order to solve this problem, it has been attempted to make the jackets and masks of athletes strong, but these cannot sufficiently prevent the danger.

The main object of the present invention is to solve the above technical problems, and it is reliable and safe to use, and is suitable for fencing, especially if the blade is damaged, it is not dangerous to the player's body. Is to eliminate the above-mentioned conventional dangers by providing a sword blade to be used for.

An important object of the present invention is to provide a device which can be used for international games, that is, which can be energized. Another important object of this invention is to provide a light weight tool that can be made with conventional machines and equipment. Another object is to provide a low manufacturing cost tool that is quick and widespread.

[0009]

The present invention is formed by layering a composite material made of synthetic resin and glass fiber or synthetic fiber, has at least one internal passage, and is electrically A blade of a sword particularly suitable for fencing, comprising a single main body capable of attaching a connectable metal tip and a metal handle to both ends.

According to the present invention, it is reliable in use,
And it is safe and there is no danger to the athlete's body even if the blade is damaged,
A blade of a sword that is preferably used for fencing is provided.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below based on the embodiments shown in the drawings. The present invention is not limited to this.

FIG. 1 is a side view of a sword blade according to an embodiment of the present invention. 2 is a sectional view of the blade taken along the plane II-II of FIG. 1, and FIG. 3 is a sectional view of the blade taken along the plane III-III of FIG. 4 and 5 are partial cross-sectional views of the blade, FIG. 4 is a partial cross-sectional view showing the first end of the blade with the first insertion portion inserted, and FIG. 5 is the second insertion portion inserted. It is a fragmentary sectional view showing the 2nd end of a blade.

In these drawings, reference numeral 1 denotes a sword blade, particularly a sword blade which can be suitably used for various kinds of competitions such as fencing flutes, sabers or epees. The blade 1 is composed of a single main body 2 formed by layering a composite material made of synthetic resin and glass fiber or other synthetic fiber. The layers of these composites are preferably formed along an axis parallel to the longitudinal axis 3 of the blade 1 in order to obtain good uniformity.

The body 2 is conical so that it can flex flexibly during use and has a large diameter first end 4
And a second end 5 of smaller diameter. The body 2 has formed therein at least one passage 6 through which a suitable electric wire such as a wire or a cable can be passed.

A metal handle 7 can be attached to the first end 4 of the body 2. This metal handle 7 is a passage 6
It has a first insertion part 8 that can be inserted into the first end part 4, an annular collar 9 that contacts the edge 10 of the first end part 4, and a cylindrical first head part 11 for connecting to a handle. Also, this metal handle 7
Has a shaft hole 12 through which an electric wire such as a wire or a cable arranged inside the passage 6 can be passed.

A protruding end 13 can be attached to the second end 5 of the main body 2. This tip 13 is made of metal so that it can be energized, and is a second end that can be inserted into the passage 6.
It has a plug-in portion 14 and a second head portion 15 having a conical or truncated cone shape whose cross section is substantially truncated.

The tip 13 is of a type which is firmly attached to the inside of the hole of the second end 5 by means of a metal ring and is constituted by a bush having a known means for transmitting an electric signal. Good.

With the above-mentioned structure, even if the blade has a breakage having a shearing portion which is transverse or substantially orthogonal to the longitudinal axis, it is a breakage at a position close to the hand. Because of its wide cross-section and optimal flexibility of the blade, even if the broken tip of the blade comes into contact with the jacket of the opponent, it will not damage the opponent, which makes it easier to use. It will be appreciated that a blade that is reliable and safe, primarily for fencing tools, is provided and that the intended purpose of the invention is achieved.

By providing a passage inside the blade,
The blade can be given good elasticity and can be energized by an electric wire such as a wire or a cable, so that the blade can be used as a sports article that can be used in an international game. Finally, the blade obtained according to the invention is light in weight and cheap to manufacture, as well as less expensive to manufacture than conventional metal blades.

The blade according to the present invention can of course be variously modified within the scope of the same inventive idea. Also, the materials and dimensions that make up the individual elements of the blade can, of course, be the most appropriate according to the particular requirements.

[0021]

According to the present invention, even if the blade is damaged, the player's body will not be injured, so that the blade can be made reliable and safe in use. Also,
Since it can be energized, it can be used for international games. Furthermore, it can be manufactured with conventional machines and equipment, and the weight can be reduced.
