産業上の利用分野
本発明はスポーツ用防具や工事用保安具及びその他の防
護具に使用し得る緩衝部材に関するものである。DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a buffer member that can be used in sports equipment, construction equipment, and other protective equipment.
従来の技術
従来の此種緩衝部材としては、自動車用エアダンパーや
ショックアブソーバ−等にみられる如く、衝撃力を受け
る部材が長い時間をかけて変位する事により衝撃を吸収
する構成のものと、衝撃を受ける部材が有弾性物体で、
その弾性により衝撃力を吸収する構成のものとがある。BACKGROUND OF THE INVENTION Conventional shock absorbing members of this type include those that absorb shock by displacing a member that receives impact over a long period of time, such as those found in automobile air dampers and shock absorbers. The member receiving the impact is an elastic object,
Some have a configuration that absorbs impact force due to its elasticity.
発明が解決しようとする問題点
上記従来緩衝部材中、前者は衝撃力を受ける部材の変位
量が太きいためスポーツ用防具や保安具等の如き小型の
緩衝具には適しないし、又後者は自己の弾性によって衝
撃力を吸収するため、急激且つ強力な衝撃力に対しては
効果のある吸撃作用が期待出来ない。Problems to be Solved by the Invention Among the above-mentioned conventional shock absorbing members, the former is not suitable for small shock absorbers such as sports armor and safety gear because the amount of displacement of the member receiving the impact force is large, and the latter is not suitable for self-sustaining shock absorbers. Since the impact force is absorbed by the elasticity of the material, an effective absorbing action cannot be expected against sudden and strong impact forces.
本発明はこの様な問題を解決し得る緩衝部材を提供する
ものである。The present invention provides a buffer member that can solve these problems.
問題点を解決するための手段
本発明は変形可能な受圧面を有する外装体内に針入度ｉ
ｏｏ〜２００望ましくは１３０〜１７０のゲル物質を封
入し、このゲル物質の分子間摩擦によって受圧面から受
ける衝撃力を全方向に微細分化して分散させる事を特徴
としている。Means for Solving the Problems The present invention provides a method for increasing the penetration depth i into an exterior body having a deformable pressure-receiving surface.
It is characterized by enclosing a gel substance of 0 to 200 mm, preferably 130 to 170 mm, and finely dividing and dispersing the impact force received from the pressure receiving surface in all directions due to intermolecular friction of the gel substance.
作用
受圧面に衝撃力が加はると、内部のゲル物質は変形して
衝撃力を拡散するが、本発明緩衝部材のゲル物質は針入
度が１００〜２００であるから、弾性が焦視出来る程度
に小さいと共に変形度も小さいから、衝撃力の分散効果
が極めて良好である。When an impact force is applied to the acting pressure-receiving surface, the gel material inside deforms and diffuses the impact force, but since the gel material of the cushioning member of the present invention has a penetration degree of 100 to 200, its elasticity is Since it is as small as possible and the degree of deformation is also small, the impact force dispersion effect is extremely good.
実施例
第１図に示す実施例は、高ダンピングゴムを材料とした
袋状の外装体１０の内部に針入度１００〜２００のゲル
物質２０を包入し、更に外装体１０の外側にナイロン布

，１２におい−て合接すると共に合接部分を縫合又は溶
着して作られている。Embodiment In the embodiment shown in FIG. 1, a gel material 20 with a penetration depth of 100 to 200 is encapsulated inside a bag-shaped exterior body 10 made of high damping rubber, and nylon is further placed on the outside of the exterior body 10. The outer cover layer 30 is made of cloth, and the outer cover layer 30 is made of cloth.
is made of two pieces of high damping rubber fabric 11.11 and its edges 12
, 12, and the joined portions are sewn or welded.
この実施例においては、上記ゲル物質として、トーレシ
リコーン株式会社の製造に係るＣＹ５２−２６４Ｇｅｌ

としては、株式会社ブリデストンの製造に係る商品名ｒ
ＺＤＥＬＪを用いている。In this example, the gel material used was CY52-264Gel manufactured by Toray Silicone Co., Ltd.
The high damping rubber mentioned above is manufactured by Brideston Co., Ltd. under the trade name r.
ZDELJ is used.
即ち、上記シリコンゲルは比重的１．針入度１５０の特
性を有し、又上記ｒＺＤＥＬＪは優れた低反発弾性を有
しているから、弾性による緩衝作用を有効に抑止する事
が出来る。That is, the silicon gel has a specific gravity of 1. Since rZDELJ has a penetration characteristic of 150 and excellent low resilience, it can effectively suppress the buffering effect due to elasticity.
この実施例に示す緩衝部材は高ダンピングゴムの外装体
ｌＯとゲル物質２０とを組合せたものであるから、衝撃
吸収時間が約５０Ｘ１／１００秒と云う比較的長い時間
であってもゲル物質の破壊が生じないと云う利点がある
。Since the shock absorbing member shown in this example is a combination of a high damping rubber exterior body lO and a gel material 20, even if the shock absorption time is relatively long, about 50×1/100 seconds, the gel material is It has the advantage that no destruction occurs.
しかしながら、衝撃力は発生源によって時間的にも又強
度的にも異るから、例へば空手用防具として本発明緩衝
部材を用いる場合には外装体１０の材料としで他の物質
を選んでも良い。However, since the impact force differs in both time and intensity depending on the source, for example, when the cushioning member of the present invention is used as karate armor, other materials may be selected as the material for the exterior body 10.
即ち、空手の如き拳法にあっては、衝撃力の最大値は６
６０ｆＭ（キログラム）にも達する事があるが、衝撃力
持続時間は２／ｌｏｏ秒〜１６７１００秒程度であるか
ら、衝撃力吸収時間の延引によってゲル物質が破壊され
る虞れが少いからである。In other words, in martial arts such as karate, the maximum impact force is 6.
This is because although the impact force can reach up to 60 fM (kilograms), the impact force duration is about 2/loo seconds to 167100 seconds, so there is little risk of the gel material being destroyed by prolonging the impact force absorption time. .
本発明緩衝部材は針入度１００〜２００のゲル物質を用
いており、実験によれば高さ１ｍから生玉子を落下させ
ても、この生玉子が割れない程度の緩衝力を有している
。The cushioning member of the present invention uses a gel substance with a penetration degree of 100 to 200, and according to experiments, it has enough cushioning power that even if a raw egg is dropped from a height of 1 meter, the raw egg will not break. .
これに対し、緩衝材として針入度９０程度のゲル物質を
選択すると、生玉子は開環され、又針入度２３０程度の
ゲル物質を選択すると、生玉子はゲル物質中に埋没して
しまうので、いづれも緩衝作用が少い事明らかである。On the other hand, if a gel substance with a penetration degree of about 90 is selected as a buffer material, the raw egg will be opened, and if a gel substance with a penetration degree of about 230 is selected, the raw egg will be buried in the gel substance. Therefore, it is clear that both have little buffering effect.
