Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】主として綱引き競技、又は、綱引き同様に一方向に力 を集中するようなスポーツ競技に使用する靴に関する。[Industrial field of application] The present invention relates to shoes mainly used in a tug of war competition or a sports competition in which the power is concentrated in one direction like a tug of war.

【0002】[0002]

【従来の技術】 従来、綱引き用の靴は種々提供されているが、その形状は 、通常の運動靴と大きな差がなく、主として体育館の床面との滑りを防ぐのを目 的としただけのものであり、人間の足首関節の曲がる角度の限界を考慮したもの ではなかった。2. Description of the Related Art Conventionally, various types of tug of war shoes have been provided, but their shapes are not much different from those of ordinary sports shoes, and their main purpose is to prevent slipping on the floor of a gym. However, it did not consider the limit of the bending angle of the human ankle joint.

【0003】[0003]

【考案が解決しようとする課題】 綱引き競技における勝敗は、筋力だけで 決まるのではなく、フォームが大きな要素を占めている。それは、体を腰などで 曲げず、腰、背中、膝を真っ直ぐに伸ばしたままで、後方へ倒れ込むことにより 、体重が引く力に加重されるようにすることにある。よって、重要なことは、体 を後方へ倒す角度が、低ければ低いほど良いということになる。 その倒れる角 度を低くするための綱引き用靴を提供することを目的とする。[Problems to be solved by the device] In a tug of war competition, victory and defeat are not determined solely by muscle strength, but form is a major factor. That is, the body is not bent at the waist and the waist, back, and knees are straightened, and the body is leaned backward so that the weight is applied to the pulling force. Therefore, what is important is that the lower the tilt angle of the body, the better. It is an object of the present invention to provide tug of war shoes for reducing the fall angle.

【0004】[0004]

【課題を解決するための手段】 従来、体を後方へ倒す角度を低くする為に は、床面と靴との摩擦力を大きくする事が重要であると考えられ、ゴム質や、靴 底の凸凹模様などが改良されてきたが、勿論それも重要なことだが、もう一つ重 要なことは、人間の足首が後方へ曲がる角度には限界があり、足の裏を床に着け たままで、体を直線状態に保ったまま後方へ倒すことには限界がある。 つまり、足首関節の後方への折れ角が限界にきた時、膝の関節が曲がり始めるの で、膝の関節にかかるモーメントが増大し、それに耐える為に筋力を多く使うこ とになり、膝の上下にある筋力の限界点を超えると、さらにフォームが崩れ、勝 敗が決する。[Means for Solving the Problems] Conventionally, it has been considered important to increase the frictional force between the floor surface and the shoe in order to reduce the angle at which the body is tilted backward. Although the unevenness pattern has been improved, of course, it is also important, but another important thing is that there is a limit to the angle at which the human ankle can bend backwards, and the sole of the foot must be worn on the floor. Until then, there is a limit to how much you can lean backward while keeping your body straight. In other words, when the backward bending angle of the ankle joint reaches its limit, the knee joint begins to bend, increasing the moment applied to the knee joint and using a lot of muscle strength to endure it, and If you exceed the upper and lower limits of your muscle strength, your form will collapse further and you will win or lose.

【0005】 よって、膝を曲げないまま、体を後方に倒せる様にする為に、足首関節の後方へ の曲がる角度を補うように靴底を形成したことが、この考案のポイントとなって いる。その為に、靴の踵部分に対して爪先が高くなるようにし、かつ、床との摩 擦力が変わらないようにした靴を提供するものである。Therefore, the point of this invention is to form the shoe sole so as to compensate for the angle of the ankle joint bending backward so that the body can be tilted backward without bending the knee. . Therefore, the present invention provides a shoe in which the toes are higher than the heel portion of the shoe and the frictional force with the floor does not change.

【0006】 さて、その靴底の傾斜角3の大きさの決定についてであるが、極端にその角度 を大きし、爪先を上げ、体の後傾角度を低くしすぎると、床面と靴底面の垂直抗 力を小さくしてしまい、摩擦力が小さくなる。 そこで、その角度を決定するに は、床面と体育館用の運動靴との摩擦力の限界をつかむことが、重要事項となる 。Now, regarding the determination of the size of the inclination angle 3 of the shoe sole, if the angle is extremely increased, the toes are raised, and the rearward inclination angle of the body is too low, the floor surface and the sole surface of the shoe are reduced. The normal force of is reduced and the frictional force is reduced. Therefore, in determining the angle, it is important to grasp the limit of frictional force between the floor surface and the sports shoes for gymnasium.

【0007】 以下に、その靴底の傾斜角3の大きさの決定方法を具体例を用いて説明する。 ホコリ・油分等をとり、きれいにした体育館の床面と同等の表面を持つ平板を 用意し、その斜面にバスケットシューズを置き、すべりはじめる時の正接を求め ると、 2.0 の数値を得た。 これは摩擦係数であり、その正接に相当する 角度は、約64度である。 よって、90度からそれを差し引いた角度、つまり 、26度が、床面から測った限界後傾角度となり、この角度の大きさが、その靴 を用いた場合の最大摩擦力を得る角度となる。Hereinafter, a method of determining the size of the inclination angle 3 of the shoe sole will be described using a specific example. A flat plate with a surface equivalent to the floor of the gymnasium, cleaned of dust and oil, was placed, basket shoes were placed on the slope, and the tangent at the beginning of sliding was calculated, and a value of 2.0 was obtained. . This is the coefficient of friction, and the angle corresponding to its tangent is about 64 degrees. Therefore, the angle obtained by subtracting it from 90 degrees, that is, 26 degrees, is the limit rearward inclination angle measured from the floor surface, and the size of this angle is the angle at which the maximum frictional force is obtained when the shoe is used. .

【0008】 また、これに対して、競技者の足首の肉体的な後傾角度の限界が、床面から 40度であったとすると、この数値と、前記の限界後傾角度26度との差、つま り14度が、体の理想の後傾角度を得る為に必要とされる靴底の傾斜角3となる 。 つまり、この時に、前記の靴底の摩擦力が最大限に生かされると共に、膝の 上下の筋肉に不必要な負担をかけず、体重をより多く綱にかけることが可能にな る。 勿論、摩擦係数のもっと大きな靴底があれば、さらに限界後傾角度を低くする ことができる。On the other hand, if the limit of the physical backward tilt angle of the athlete's ankle is 40 degrees from the floor surface, the difference between this numerical value and the above-mentioned limit rear tilt angle of 26 degrees. That is, 14 degrees is the sole angle of inclination 3 required to obtain the ideal backward inclination angle of the body. In other words, at this time, the frictional force of the sole is maximized, and it becomes possible to apply more weight to the rope without imposing an unnecessary burden on the muscles above and below the knee. Of course, if you have a sole with a larger coefficient of friction, you can further reduce the rearward tilt angle.

【実施例】【Example】

この考案の一実施例を図面に基づいて説明する。 この考案の綱引き用靴は、図1及び図2に示すように、靴本体1に、靴底2が結 合した形状をしている。 靴底2は、合成ゴム、合成樹脂等で造られ、靴底2の上面は、靴本体1の底面 と同形状で、靴本体1と靴底2は、接着剤による接着、または、一体成型にて造 られ、横すべり力に充分に耐えるよう、強く結合している。 An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the tug of war shoe of the present invention has a shape in which a shoe body 1 is joined to a shoe body 1. The shoe sole 2 is made of synthetic rubber, synthetic resin, etc., the upper surface of the shoe sole 2 has the same shape as the bottom surface of the shoe body 1, and the shoe body 1 and the shoe sole 2 are bonded by an adhesive or integrally molded. It is made of, and is strongly bonded so that it can withstand the sideslip force sufficiently.

【0010】 また、靴底2は、馬蹄と同様に、底面に近づくほど広くなっていて、床との接 触面が広く、安定し、競技中に足を挫いたりしないようにしている。 更に、靴底の傾斜角3については、足首の後傾角度の個人差によって差異があ るが、一般には、約13度の角度が適当である。また、靴底の爪先部の角4は、 競技者の足の親指の付け根が靴底を押す力を床面に伝えるのに必要な角度だけ前 方に開いた大きさであり、110度乃至は120度が適当である。 なお、靴底の模様に関しては、通常の体育館用シューズとほぼ同じく、通常の 摩擦係数を持つものであれば良い。Further, like the horseshoe, the shoe sole 2 is wider toward the bottom so that the contact surface with the floor is wide and stable so that the foot is not crushed during the competition. Further, the inclination angle 3 of the shoe sole varies depending on the individual difference in the backward inclination angle of the ankle, but in general, an angle of about 13 degrees is suitable. In addition, the corner 4 of the toe of the shoe sole is a size that is opened forward by an angle necessary for the base of the athlete's big toe to transmit the force pushing the shoe sole to the floor surface. 120 degrees is suitable. As for the sole pattern, any shoe with a normal coefficient of friction may be used, similar to the shoes for a normal gym.

【考案の効果】[Effect of the device]

この靴の使用により、膝を真っ直ぐ伸ばしたまま十分体を後傾させる事ができ るので、今までの膝の曲がりに耐える筋肉の力への負担が軽減され、筋肉の力を 最大限効率的に使用する事ができるので、体重をより多く綱にかけることができ て、綱引き競技における勝率が向上する。 The use of these shoes allows you to lean backward enough while keeping your knees straight, which reduces the strain on the muscles that can withstand knee bending and maximizes muscle efficiency. Since it can be used for, you can put more weight on the rope and improve the winning rate in the tug of war.
