が使用されている。Conventional technology and its problems For example, running shoes are required to have good shock absorption properties to reduce the burden on the feet, and are also required to be lightweight and have a moderate degree of elasticity to reduce energy loss. be done. For this reason, materials with rubber-like elasticity such as rubber and synthetic resin are used in the soles of conventional running shoes.
ところで、ランニング中にかかとにかかる衝撃力は、舗
装路で体重の約２．６倍にも遠する。By the way, the impact force applied to the heel during running on a paved road is about 2.6 times the body weight.

じれる。In order to protect your feet from such a large impact force,
The soles of the shoes are thickened to improve shock absorption. However,
By making the soles thicker, new types of injuries caused by twisting the ankle can be prevented, such as ligamentum inflammation, which injures the ligaments on the outside of the knee, and shin splints, which inflame the ligaments on both sides of the shin. came out. The impact force applied to the heel during running is not necessarily uniform over the entire sole of the foot, and depending on the way you run, there may be areas where an abnormally large force is applied, and the impact force in these areas can be 4 to 5 times your body weight. For this reason, the ankle twists toward the side where the impact force is greater, and this twist becomes larger as the sole becomes thicker. For example, in the case of X-legged feet, which is common among Europeans and Americans, the impact force on the inside of the foot is large, causing the ankle to twist inward. On the other hand, in the case of zero legs, which is common among Japanese people, the impact force on the outside of the foot is large, causing the ankle to twist outward.

ことができず、また、全ての人の足首のねじれを防止で
きるようにしようとすれば多種類の靴底が必要になる。In order to prevent such ankle twisting, running shoes have been proposed in the United States in which the inner part of the sole of the heel is harder than the outer part. When a person with X-legged feet wears such running shoes, it is possible to prevent the ankle from twisting inward. However, when Japanese people used such running shoes, the incidence of ankle twisting problems actually increased. This is because the hardness of the inside of the heel of the sole of the shoe increases the amount of outward twisting of the ankle, which is common among Japanese people. By making the outer part of the heel of the sole harder than the inner part, it is possible to prevent the ankle from twisting outward. However, the way of running and the degree of ankle twisting vary from person to person, and even for the same person, the left foot and right foot may differ, and the twisting may move sequentially from the outside to the inside. One type of sole cannot sufficiently prevent ankle twists for all people, and multiple types of soles are required to prevent ankle twists for all people. become.

。このため、高速走行時にはタイヤの空気圧を２０〜３
０％程度高目にしているが、このようなタイヤの空気圧
の調整は面倒で手間がかかる。Furthermore, in the case of conventional automobile tires, it is necessary to change the air pressure between normal driving and high-speed driving. This is because if the tire air pressure is too high, the 11M during normal driving will be large and the ride will be uncomfortable, and if the tire air pressure is too low, a phenomenon called standing wave will occur when driving at high speeds, which can cause tire damage. This is because it causes For this reason, when driving at high speeds, the tire pressure should be set at 20 to 3
I set it high by about 0%, but adjusting tire air pressure like this is troublesome and time-consuming.

が激しくなり、危険である。Furthermore, in the case of centrifugal separators (including dewatering devices for electric washing machines, etc.), the contents of the centrifugal separator are not perfectly balanced in the container, which causes the rotating shaft to wobble during rotation. For this reason, in conventional centrifuges, the rotating shaft is supported by a bearing using a cushioning material made of a substance with rubber-like elasticity.
I am trying to tolerate some blurring. By the way, if this vibration of the rotating shaft is not tolerated to a certain extent, an actual centrifugal machine cannot operate, but if it exceeds this vibration, the vibration becomes violent and is dangerous.
ところが、上記のような従来の緩衝材料を使用した軸受
では、回転軸のぶれが大きくなっても、これを防止する
ことができない。However, with the above-mentioned conventional bearings using cushioning materials, even if the vibration of the rotating shaft becomes large, it cannot be prevented.
この発明の目的は、上記のような問題を解決するために
、大きな外力が作用した部分の硬度のみを高めることが
できる緩衝材料を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a cushioning material that can increase the hardness of only the portions on which a large external force is applied, in order to solve the above-mentioned problems.

剤が入れられていることを特徴とするものである。Means for Solving the Problems The cushioning material according to the present invention has a sealed space formed inside a main body made of a substance having rubber-like elasticity, and when an external force of a predetermined value or more is applied within this sealed space, the hardness decreases. It is characterized by the addition of a reinforcing agent.

In addition, in this ms, the term dispersion is used as a general term for a system in which solid or liquid fine particles are dispersed in a liquid, and this includes all solutions, suspensions, emulsions, etc. It will be done. Examples of dispersions exhibiting reverse thixotropy include concentrated aqueous solutions of polymethacrylic acid and 42% gypsum paste. Examples of dispersions exhibiting rheopexy include a suspension of titanium white fine particles, a suspension of titanium oxide fine particles, and an acetone suspension of polystyrene fine particles. Dispersions exhibiting tylatancy include, for example, so-called plastisols, in which particles of polymers such as polyvinyl chloride are dispersed in plasticizers, paints or printing inks with a high solids content, potassium silicate, bentonite sols or pentoxides. These include suspensions of anisotropic particles such as vanadium, zinc oxide, etc.

It consists of a solidifying agent that solidifies the main material when mixed with the main material, and the main material and the curing agent are mixed by external pressure. As the base agent and hardening agent, for example, a combination of a base agent and a hardening agent of an epoxy resin two-component adhesive is used.

増し、その部分の緩衝材料の硬度も増す。そして、外力
がなくなると、硬度は元に戻る。If the reinforcing agent is a dispersion that exhibits reverse thixotropy, rheopexy, or tylatancy, when a large external force acts on a certain part of the buffer material, the hardness of the reinforcing agent in that part increases, and the hardness of the buffer material in that part increases. It also increases. Then, when the external force is removed, the hardness returns to its original state.

ある部分に大きな外力が作用すると、その部分の補強剤
が結晶化して硬度を増し、その部分の緩衝材料の硬度も
増す。この場合、外力がなくなっても、硬度はそのまま
であり、元に戻らない。If the reinforcing agent is a polymer solution that crystallizes when oriented by external pressure or a rubber that crystallizes under stretching tension, when a large external force is applied to a certain part of the buffer material, the reinforcing agent in that part will crystallize and reduce its hardness. This increases the hardness of the cushioning material in that area. In this case, even if the external force is removed, the hardness remains the same and does not return to its original state.
補強剤が主剤と固化剤とからなる場合、緩衝材料のある
部分に大きな外力が作用すると、その部分の主剤が固化
剤と混合して固化し、その部分の緩衝材料の硬度が増す
。この場合も、外力がなくなっても、硬度はそのままで
あり、元に戻らない。When the reinforcing agent consists of a base material and a solidifying agent, when a large external force acts on a certain part of the buffer material, the base material in that part mixes with the solidifying agent and solidifies, increasing the hardness of the buffer material in that part. In this case, even if the external force is removed, the hardness remains the same and does not return to its original state.
実 施 例 以下、図面を参照して、この発明の詳細な説明する。Example Hereinafter, the present invention will be described in detail with reference to the drawings.
第１図は、直方体ブロック状の緩衝材料の１例を示す。FIG. 1 shows an example of a cushioning material in the form of a rectangular parallelepiped block.
この緩衝材料の本体（１）は、上面に凹所（２）が形成

）の上面に接着された方形板状のｉ （１ｂ）とからな

剤（４）が封入されている。The main body (1) of this buffer material consists of a container (1a) in the shape of a rectangular parallelepiped block with a recess (2) formed in the upper surface, and a container (1a).
), and a reinforcing agent (4) is enclosed in a sealed space (3) formed in a recess (2).

い。Container (1a) and! (1b) consists of a soft rubber, and the reinforcing agent (4) consists of a 50% polyvinyl chloride dispersion. In addition,! (1b) is glued to the container (1a) after placing the reinforcing agent (4) in the recess (2). In addition, a container (1
After bonding M (1b) to a), the reinforcing agent (4) may be injected into the closed space (3) using a syringe or the like.
上記の緩衝材料の作用を確認するため、これを振動発生
装置に装着して、固定盤との間に挾み、撮動数５Ｈｚ、
加速度１〜４Ｇの負荷で圧迫した。In order to confirm the effect of the above-mentioned buffer material, it was attached to a vibration generator, sandwiched between it and a fixed plate, and the frequency of imaging was 5Hz.
Compression was applied with an acceleration of 1 to 4 G.
このときの緩衝材料の振幅の変化を第２図に示す。FIG. 2 shows the change in the amplitude of the buffer material at this time.
第２図より、振動強度がある値以上になると緩衝材料の
振幅が減少することがわかる。これは、後述するように
、密閉空間（３）内に封入されたポリ塩化ビニル分散液

めと考えられる。そして、補強剤（４）やこれを入れる
密閉空間（３）の形状などを変えることにより、どの程
度の撮動強度で硬度が増すかを調節することが可能であ
る。From FIG. 2, it can be seen that when the vibration intensity exceeds a certain value, the amplitude of the buffer material decreases. This is considered to be because the hardness of the buffer material as a whole increased due to the increase in the viscosity of the polyvinyl chloride dispersion liquid sealed in the closed space (3), as will be described later. By changing the shape of the reinforcing agent (4) and the sealed space (3) in which it is placed, it is possible to adjust the degree of imaging intensity at which the hardness increases.

０％ポリ塩化ビニル分散液を円錐型回転粘度計に入れ、
ずり応力を変えて、ずり粘度の変化を観察した。In addition, in order to confirm the effect of the reinforcing agent (4) above, 5
Put the 0% polyvinyl chloride dispersion into a conical rotational viscometer,
Changes in shear viscosity were observed by changing shear stress.
その結果を第３図に示す。The results are shown in FIG.
第３図より明らかなように、粘度はずり速度が１０ （
１／ ５ｅｃ）のところで急激に上昇した。したがって
、外力がこの値以下では分散液の粘度が低いが、この値
以上になると分散液の粘度が上昇して硬度が増すことが
わかる。As is clear from Figure 3, the viscosity has a shear rate of 10 (
It rose sharply at 1/5 ec). Therefore, it can be seen that when the external force is below this value, the viscosity of the dispersion is low, but when it exceeds this value, the viscosity of the dispersion increases and the hardness increases.
第４図〜第６図はランニングシューズの靴底の１例を示
し、この靴底の本体（１０）は、通常のものと同様、ゴ
ム、合成樹脂などのゴム状弾性を有する物質よりなる。FIGS. 4 to 6 show an example of a sole of a running shoe, and the main body (10) of this sole is made of a material having rubber-like elasticity such as rubber or synthetic resin, like a normal shoe sole.

の密閉空間（１１）が形成されており、各空間（１１）
には所定値以上の外力が作用したときに硬度の増す補強
剤（１２）が入れられている。A large number of sealed spaces (11) are formed in the inner part (10a) and the outer part (10b) of the sole body (10) in multiple rows above and below and in multiple rows on the left and right, and each space (11)
contains a reinforcing agent (12) that increases in hardness when an external force of a predetermined value or more is applied.
靴底本体（１０）の内部に密閉空間（１１）を形成して
補強剤（１２）を入れる方法は、任意である。たとえば

てもよい。The method of forming a sealed space (11) inside the sole body (10) and introducing the reinforcing agent (12) is arbitrary. For example, the sole body (10) is divided into multiple sheets vertically, holes are drilled in the necessary sheets to form the sealed space (11), and these sheets are stacked and joined one on top of the other, reinforcing the holes. Add agent (12). In addition, after joining a plurality of such sheets to form a plurality of sealed spaces (11) inside, reinforcing agent (12) is injected into these sealed spaces (11) using a syringe or the like. Good too. Alternatively, the sole body (10) may be integrally molded by placing the reinforcing agent (12) in small capsules and arranging a plurality of capsules at predetermined positions in a mold.

ｏｂ）の補強剤（１２）の硬度が増す。The reinforcing agent (12) used is, for example, a dispersion exhibiting reverse thixotropy, rheopexy or tyratancy. When this shoe is worn by a person whose ankle twists inward, a large impact force is applied to the inner side of the heel, which increases the hardness of the reinforcing agent (12) in the inner portion (10a) of the sole. For this reason, the hardness of the inner part (10a) of the sole increases,
This prevents the ankle from twisting inward. Conversely, if this shoe is worn by a person whose ankle twists outward, a large impact force is applied to the outside of the heel, which causes damage to the outside part of the sole (i.e.
The hardness of the reinforcing agent (12) of ob) increases.
このため、靴底の外側部分（１０ｂ）の硬度が増し、足

はいた場合またはこれと逆の場合などでも、常に足首の
ねじれを防止することができる。This increases the hardness of the outer part (10b) of the sole and prevents the ankle from twisting outward. In addition, if a person wears a shoe whose torsion moves sequentially from the outside to the inside, the hardness of the outside part (10b) and the inside part (10a) of the sole will increase in proportion to the degree of twist, causing the ankle torsion. is prevented. In either case, when the impact force is removed, the hardness of the reinforcing agent (12) gradually returns to its original state.
The hardness of the entire sole of the shoe returns to its original level. Therefore, even if a person whose ankle turns inwards wears shoes that are worn by a person whose ankle turns outward, or vice versa, ankle twisting can always be prevented.

底の内側部分（１０ａ）の補強剤（１２）が結晶化して
硬度を増す。Also used as the reinforcing agent (12) is, for example, a polymer solution that crystallizes when oriented by external pressure or a rubber that crystallizes under stretching tension. When this shoe is worn by a person whose ankle twists inward, when a large impact force is applied to the inside of the heel, the reinforcing agent (12) in the inside part (10a) of the sole crystallizes and increases its hardness.
これにより、靴底の内側部分（１０ａ）の硬度が増すた
め、足首の内側へのねじれが防止される。This increases the hardness of the inner part (10a) of the sole, thereby preventing the ankle from twisting inward.
そして、衝撃力がなくなっても、補強剤（１２）＋よ結
晶化したままであり、硬度は元に戻らない。Even when the impact force is removed, the reinforcing agent (12) remains crystallized and the hardness does not return to its original state.

ューズを異なる人が使用するのは好ましくない。しかし
ながら、同一人が使用する限り、十分に足首のねじれを
防止することができる。Therefore, the hardness of the sole remains high at the inner part (IQa) and does not return to its original hardness. The same applies when new shoes are worn by a person whose ankle twists outward or whose ankle moves sequentially from the outside to the inside. In this case, the inner part (10a) or the outer part (10b) of the sole
Once the hardness of the shoes increases, it cannot return to its original state, so it is not desirable for the same shoe to be used by different people. However, as long as the same person uses it, twisting of the ankle can be sufficiently prevented.
補強剤として、単独では硬度の低い主剤と、主剤と混合
することによって主剤を固化させる固化剤とからなるも
のを用いることもできる。As the reinforcing agent, it is also possible to use one consisting of a main material that has low hardness when used alone, and a solidifying agent that solidifies the main material when mixed with the main material.
第７図および第８図はこのような２つの例を示す。Figures 7 and 8 show two such examples.

は戻らない。In the case of FIG. 7, the sealed space (13) is a narrow space that communicates with a base agent storage chamber (13a) that stores a base agent (14) and a solidification agent storage chamber (13b) that stores a solidification agent (15). A plurality of these sealed spaces (13) are formed in the sole body (10) similarly to the sealed spaces (11) in FIGS. 4 to 6. When no impact force is applied, the base material (14) and the solidifying agent (15) do not mix, and their hardness is low. When an impact force is applied, the base agent (14) and solidifying agent (15) are mixed through the communication path (13C), and the base agent (14) is solidified. Then, the hardness of the sole (10) increases in the part where the base agent (14) has solidified. In this case as well, once the base material (14) solidifies, it does not return to its original state.
第８図の場合、主剤（１４）が密封された多数のカプセ

ル（１１）が各密閉空間（１８）内に入れられている。In the case of FIG. 8, a large number of capsules (1G) sealed with a base agent (14) and a large number of capsules (11) sealed with a solidifying agent (15) are placed in each sealed space (18).

合と同様である。Note that a plurality of these closed spaces (18) are also formed within the sole body (10), similar to the closed spaces (11) in FIGS. 4 to 6. When no impact force is applied, the base material (14) and the solidifying agent (15) do not mix. When impact force is applied, the capsule (16017) is damaged and the main ingredient (14)
is mixed with the solidifying agent (15) and solidified. The rest is the same as in the case of FIG.
この発明による緩衝材料は、ランニングシューズの靴底

走行でタイヤの空気圧を変える必要がなくなる。When applied to automobile tires, the body of the cushioning material is shaped into the shape of the tire. In this way, the hardness of the entire tire increases during high-speed driving with large external forces, so that stunting waves can be prevented without particularly increasing the air pressure. This eliminates the need to change tire pressure between normal driving and high-speed driving.

できる。Effects of the Invention Since the buffer material according to the present invention has the above-mentioned configuration,
It is possible to increase the hardness only in the area where a large impact force is applied. Therefore, if applied to the soles of running shoes, for example, it is possible to prevent twisting of the ankles of all people who run in different ways and twist their ankles simply by preparing one type of sole. Furthermore, if applied to automobile tires, it is possible to prevent the standing wave phenomenon during high-speed driving without particularly increasing the air pressure, and there is no need to change the air pressure between normal driving and high-speed driving. Also,
If applied to a bearing for centrifugal separation, the hardness increases when the vibration of the rotating shaft increases, so vibration can be reduced.
