この考案は、運動靴靴底の溝形状に係り、例え
ばゴルフシユーズやランニングシユーズ、テニス
シユーズ等の運動靴の靴底に形成された溝形状の
改良に関する。[Detailed description of the invention] [Industrial application field] This invention relates to the shape of grooves in the soles of athletic shoes, such as grooves formed in the soles of athletic shoes such as golf shoes, running shoes, and tennis shoes. Concerning shape improvement.
第８図および第９図は、ゴルフシユーズ、テニ
スシユーズ、マラソンシユーズ等の運動靴の一般
的な構成を示す側面図である。
FIGS. 8 and 9 are side views showing the general structure of athletic shoes such as golf shoes, tennis shoes, marathon shoes, etc.
ゴルフシユーズ、テニスシユーズ、マラソンシ
ユーズ等の運動靴B.B′は、靴使用時に足全体を
包み込む靴本体１３，１６と、この靴本体１３，
１６の下面に形成された靴底１４，１５とからな
つている。また、運動靴はその使用目的から、第
８図に示すように、靴底１４を構成する表底１１
と靴本体１３の間に、接地面からの衝撃を吸収す
るウレタン等のクツシヨン材１２を介在している
のが一般的である。 Athletic shoes BB' such as golf shoes, tennis shoes, marathon shoes, etc. have shoe bodies 13, 16 that wrap around the entire foot when the shoes are in use, and shoe bodies 13, 16,
It consists of soles 14 and 15 formed on the lower surface of shoe 16. In addition, because of the purpose of use of athletic shoes, as shown in FIG.
Generally, a cushion material 12 such as urethane is interposed between the shoe body 13 and the shoe body 13 to absorb shock from the ground surface.
そして、靴底１４，１５の接地面には通常、走
行の際の排水性を向上させたり、路面把握力を高
める目的で様々の形状の溝１０，１７や突起など
が形成されている。 Grooves 10, 17 and protrusions of various shapes are usually formed on the contact surfaces of the soles 14, 15 for the purpose of improving water drainage during running and increasing grip on the road surface.
ところで、上述したような運動靴Ｂ，B′は、
クツシヨン材としての中底１２を厚くするほど緩
衝効果が増し、また、表底１１または靴底１５の
厚みを厚くするほど耐久性が向上する。
By the way, the athletic shoes B and B′ mentioned above are
The thicker the insole 12 as a cushion material is, the more the cushioning effect is increased, and the thicker the outsole 11 or the sole 15 is, the more the durability is improved.
従つて、緩衝効果が高く且つ寿命の長い運動靴
を得ようとすれば必然的に靴底１４，１５は厚く
なる。 Therefore, in order to obtain athletic shoes with a high cushioning effect and a long lifespan, the soles 14 and 15 inevitably become thicker.
しかし、靴底１４，１５が厚くなるほど靴底１
４，１５を湾曲させる際に靴底１４，１５の接地
面を大きく伸長させなけらばならず、必然的に靴
底１４，１５は曲げにくくなる。 However, the thicker the soles 14 and 15, the more
When bending the soles 4 and 15, the ground contact surfaces of the soles 14 and 15 must be greatly expanded, which inevitably makes the soles 14 and 15 difficult to bend.
すなわち、靴底１４，１５の厚い運動靴Ｂまた
はB′を履いた使用者は、階段や坂道の登り降り
の際、あるいはマラソンやゴルフ場で芝目を読む
ために片膝立ちでしやがむ場合などにおいて、靴
底１４，１５を湾曲させるために大きな力が必要
となり、従つて疲れ易くなる。 In other words, a user wearing athletic shoes B or B' with thick soles 14 and 15 may stand on one knee when climbing or descending stairs or a slope, or when running a marathon or on a golf course to read the grass. In such cases, a large amount of force is required to bend the soles 14, 15, and the wearer becomes easily fatigued.
また、靴底１４，１５の爪先接地面は、靴底が
薄い場合に比して地面との摩擦力が大きく、早期
に磨耗するという問題点を有している。 Further, the toe contact surfaces of the soles 14 and 15 have a problem in that the frictional force with the ground is greater than in the case where the soles are thin, and they wear out quickly.
さらに、靴底が厚くなれば運動靴使用の際の接
地面の伸縮量が大きくなり、曲げの繰り返しによ
る靴底の疲労劣化が早くなる。 Furthermore, if the sole becomes thicker, the amount of expansion and contraction of the contact surface during use of the athletic shoe increases, and fatigue deterioration of the sole due to repeated bending becomes faster.
このような問題点を解決するために、靴底の材
質が種々異なる運動靴が開発、販売されている
が、伸縮性の大きい材質のものを使用すれば靴底
の寿命が短くなり、伸縮し易く且つ磨耗しにくい
材質のものを靴底として使用すれば運動靴の価値
が高くなるという問題点を有していた。 In order to solve these problems, athletic shoes with soles made of various materials have been developed and sold, but if shoes are made of highly elastic materials, the lifespan of the soles will be shortened and the soles will not stretch or contract. If a material that is easy to wear and does not wear easily is used for the sole of the shoe, the value of the athletic shoe increases.
この考案は上記の問題点に鑑みてなされたもの
であり、その目的とするところは、耐磨耗性およ
び緩衝効果の向上のために靴底を厚くすれば、靴
底の曲げ力が大きくなつて使用者の負担が増し疲
労し易くなり、靴底が曲げ易く疲労しにくい運動

形状を改良するという極めて簡単かつ安価な方法
で上記した問題を解決することができる、運動靴
靴底の溝形状を得ようとするものである。 This idea was created in view of the above problems, and its purpose is to increase the bending force of the sole by making the sole thicker in order to improve the abrasion resistance and cushioning effect. If we are trying to create athletic shoes with soles that are easy to bend and do not cause fatigue, we need to improve the contradictory properties of the soles, which increase the burden on the user and cause fatigue. The purpose of this invention is to obtain a groove shape for the sole of an athletic shoe that can solve the above-mentioned problems by an extremely simple and inexpensive method of improving the groove shape of the sole.

摩擦力が軽減されて靴底の寿命が向上する。 Furthermore, by providing one inclined groove 3 at a position corresponding to a line connecting the base of the toes when the shoe is in use, the toe portion of the sole 1 is inclined at the same angle when the toe of the foot is bent. The shoe sole can be bent in the groove 3, thus increasing the ground contact area of the toe part and reducing the frictional force with the ground, thereby improving the life of the sole.

例および第３実施例の作用も同一なので、その説
明は省略する。 Next, the operation of the present invention will be explained using FIG.
Here, the second
This will be explained as the athletic shoe A1 of the embodiment, but since the functions of the first embodiment and the third embodiment are the same, the explanation thereof will be omitted.
運動靴A1を使用して歩行、あるいは走行する

には、靴底１の爪先部全体が接地する。 When one foot is kicked backwards when walking or running using the athletic shoe A1 , the sole 1 bends while the opening of the parallel groove 51 gradually expands from the heel side. Further, the toe portion of the sole 1 bends while the opening of the inclined groove 31 widens in accordance with the bending of the toe. When the kicking foot reaches the rearmost position, the entire toe of the sole 1 touches the ground.
本考案は上記したとおり構成されているので、
次のような効果を奏する。
Since the present invention is constructed as described above,
It has the following effects.

止することができる。 This invention can be manufactured very easily and at low cost because it is only necessary to form multiple grooves on the ground surface of the sole.When the toe part is bent when the shoe is in use, the openings of each groove formed on the ground surface open. Since the sole of the shoe expands and the sole bends sequentially from the region where the groove is formed, it is possible to obtain an athletic shoe that does not require much force during exercise and is less tiring. Furthermore, since the stretching force acting on the ground surface during use of the athletic shoe is alleviated, fatigue deterioration of the sole can be prevented, and the life of the athletic shoe can be extended. Further, since the toe portion of the sole is bent at the portion where the inclined groove is formed, the ground contact area of the toe portion is increased, and early wear of the toe portion of the sole can be prevented.
