Description

【0001】
【技術分野】
本発明は、高齢者や障害者、或いは負傷者等によって使用される杖に係り、特に、優れた衝撃吸収性が発揮され得るように改善された杖の新規な構造に関するものである。
【0002】
【背景技術】
一般に、高齢者や障害者、或いは負傷者等、日常生活において介助者が必要とされる者等は、立ち上がったり、歩行したりする際等に、自らの体重を支えるため等に、棒状杖や松葉杖、多脚杖等、各種の杖を使用している。
【0003】
ところで、それら各種の杖には、通常、その長手の支柱部材の上端部に、使用者にて把持される把持部が設けられる一方、下端部には、使用時に接地せしめられる杖先部が取り付けられてなる構造とされている。そして、一般に、かかる杖先部が、滑り抵抗に優れたエラストマ部材(ゴム部材を含む)にて構成されており、それによって、路面上や床上等での使用時に、杖先部が、それら路面や床等に対して滑り抵抗を発揮しつつ、ある程度弾性変形せしめられて、路面や床に対する滑りが防止され得ると共に、該杖先部と路面や床との接触によって生ずる衝撃が緩和され得るようになっているのである。
【0004】
しかしながら、そのような従来の杖に取り付けられているエラストマ製の杖先部は、耐摩耗性の低下を防ぐ上から、比較的に硬度の高い材料を用いて形成されており、そのために、かかる杖先部が取り付けられてなる杖が、緩衝性能において、今一つ不十分なものとなってしまうことが避けられなかったのである。
【0005】
それ故、かかる従来からの杖にあっては、例えば、少しの衝撃でも大きな痛みを感じるリウマチ患者や、その他の傷病者等が使用する杖としては、到底供され得るものではなかったのであり、その点において、大きな改良の余地が存していたのである。
【0006】
【解決課題】
ここにおいて、本発明は、上述せる如き事情を背景にして為されたものであって、その解決課題とするところは、より十分な緩衝性能が発揮され得、以て少しの衝撃でも大きな痛みを感じる傷病者等においても可及的に小さな負担で使用可能な衝撃吸収性に優れた杖を提供することにある。
【0007】
【解決手段】
そして、本発明にあっては、かかる課題の解決のために、長手の支柱部材の上端部に、使用者にて把持される把持部が設けられる一方、下端部には、使用時に接地せしめられる杖先部が取り付けられてなる杖において、前記杖先部を、前記支柱部材の下端部が挿入せしめられる、有底の取付穴を有するエラストマ部材にて構成すると共に、該取付穴内に、該エラストマ部材よりも軟質の、変形が容易な弾性材料からなる衝撃吸収体を収容して、前記支柱部材の下端部と該取付穴の底面との間に、該衝撃吸収体が介在せしめられるようにしたことを特徴とする衝撃吸収性に優れた杖を、その要旨とするものである。
【0008】
このような本発明に従う衝撃吸収性に優れた杖にあっては、支柱部材の下端部に取り付けられて、使用時に接地される杖先部が、エラストマ部材にて構成されているため、かかる杖先部が接地せしめられた際に生ずる衝撃が、該杖先部の弾性変形作用により、ある程度吸収され得るのである。しかも、そのような杖先部の支柱部材が挿入される取付穴内における、該支柱部材の下端部と該取付穴の底面との間に、該杖先部を構成するエラストマ部材よりも軟質の、変形が容易な弾性材料からなる衝撃吸収体が介在せしめられているところから、杖先部を接地させた際に、衝撃吸収体が、杖先部よりも大きな変形量で、更に容易に弾性変形せしめられ、そしてそれによって、支柱部材から、該衝撃吸収体を介して杖先部に伝達される荷重が有利に減少せしめられ得て、杖先部の接地時に生ずる衝撃が、かかる衝撃吸収体の弾性変形により、更に有効に吸収され得るようになるのである。
【0009】
それ故、かかる本発明に従う衝撃吸収性に優れた杖においては、杖先部の弾性変形による衝撃吸収作用と、衝撃吸収体の弾性変形による更に有効な衝撃吸収作用とが相俟って、単に、杖先部がエラストマ部材にて構成されただけの従来品に比して、より高度な衝撃吸収特性が効果的に発揮され得て、杖先部を接地せしめた際に、支柱部材を通じて、その上端部を把持する使用者に伝わる衝撃力が、極めて有利に小さく為され得ることとなるのである。
【0010】
従って、かくの如き本発明に従う衝撃吸収性に優れた杖においては、従来品では到底得られない、より十分な緩衝性能が有利に発揮され得、それによって、例えばリウマチ患者等、少しの衝撃でも大きな痛みを感じる傷病者等も、可及的に小さな負担で使用が可能となるのである。そして、その結果として、従来品を使用出来なかった者が使用可能となるいった、極めて優れた使用性が、効果的に発揮され得ることとなるのである。
【0011】
なお、このような本発明に従う衝撃吸収性に優れた杖の好ましい態様の一つによれば、前記支柱部材が、炭素繊維強化樹脂材料からなるパイプにて構成される。これによって、かかる支柱部材、ひいては杖全体において、優れた機械的強度と軽量性とが付与され得、以て使用性の更なる向上を図りつつ、その使用耐久性が、効果的に高められ得るのである。
【0012】
また、本発明に従う衝撃吸収性に優れた杖の別の有利な態様の一つによれば、前記杖先部がゴム製品にて形成される一方、前記衝撃吸収体が、制振性を有する熱可塑性エラストマにて形成される。これによって、杖先部の接地部位における衝撃吸収性が確保しつつ、衝撃吸収体において、制振性に基づいた振動減衰特性に由来する、より優れた衝撃吸収性能が有利に発揮され得、以て、更に一層高度な緩衝性能が発揮され得て、更なる使用性の向上が、より高いレベルで効果的に達成され得ることとなるのである。
【0013】
さらに、本発明に従う衝撃吸収性に優れた杖の望ましい他の態様の一つによれば、前記衝撃吸収体が、球状体形状や円環体形状を有して、構成される。このような構造を有する杖にあっては、例えば、杖先部に、支柱部材が挿入せしめられる取付穴を、単純なリング形状や円筒形状等の円環体形状において形成すれば、かかる取付穴内に収容される、球状体形状の衝撃吸収体と該取付孔の内面との間、或いは円環体形状の衝撃吸収体の内孔内に、それぞれ空隙が形成され、それによって、それら球状体形状乃至は円環体形状を呈する衝撃吸収体が、支柱部材から伝わる荷重にて、かかる空隙内に、一部が侵入するようにして、より容易に弾性変形せしめられ得ることとなり、以て、更に一層優れた衝撃吸収性が確保され得て、緩衝性能と使用性の向上が、より効果的に図られ得るのである。
【0014】
【発明の実施の形態】
以下、本発明を更に具体的に明らかにするために、本発明に係る、衝撃吸収性に優れた杖の構成について、図面を参照しつつ、詳細に説明することとする。
【0015】
先ず、図1には、本発明に従う構造を有する、衝撃吸収性に優れた杖の一実施形態としての棒状杖が、その正面形態において概略的に示されている。かかる図1からも明らかなように、本実施形態の棒状杖は、その本体を与える長手の支柱部材10と、該支柱部材10の上端部に設けられた把持部12と、該支柱部材10の下端部に取り付けられた杖先部14とを有して、構成されている。
【0016】
そして、この棒状杖の本体を構成する支柱部材10は、炭素繊維強化樹脂、例えば、カーボン繊維クロス強化樹脂製の円筒パイプからなっている(図2参照)。即ち、ここでは、支柱部材10が、例えば、所定本数にて一束とされた、カーボン繊維の長繊維の各束が縦横に製織されてなる平織状のクロスに、エポキシ樹脂等の所定の樹脂材料を含浸せしめ、そして、かかるクロスを円筒状に巻き付けて、該クロス内に含浸せしめられたエポキシ樹脂材料を加熱硬化せしめる等して成形されたパイプにて、構成されているのである。
【0017】
また、把持部12は、全体として、略T字形形状を呈しており、支柱部材10と同様なカーボン繊維クロス強化樹脂製の一体的なパイプ製品からなっている。そして、かかる把持部12にあっては、T字形の頭部と脚部が、それぞれ、ハンドル部16と固着部18とされ、この固着部18において、支柱部材10の上端部に外嵌されて、固着されていると共に、そのような支柱部材10への固着状態下で、ハンドル部16が、使用者によって把持され得るように構成されているのである。
【0018】
なお、このような把持部12や支柱部材10の構成材料は、例示の如きカーボン繊維クロス強化樹脂に何等限定されるものではなく、アルミニウム合金等の金属材料や木材、或いはカーボン繊維クロス強化樹脂以外の炭素繊維強化樹脂、更には炭素繊維強化樹脂以外の樹脂材料であっても良い。また、例示の如きカーボン繊維クロス強化樹脂を用いる場合にあっても、かかる樹脂材料を与えるカーボン繊維の種類は、特に限定されるものではなく、例えば、ポリアクリロニトリル系やピッチ系等、各種のものの中から、機械的強度に優れたものが、適宜に選択、使用され得るのでり、更に、エポキシ樹脂の種類も、特に限定されるものではなく、常温で固体の性状を有するものであれば、如何なる種類のものも、有利に採用され得るのである。
【0019】
一方、かかる支柱部材10の下端部に取り付られる杖先部14は、図2に示されるように、従来品と同程度の50〜70°の硬度(ショアA型デュロメーターにより測定した値)を有する、公知のゴム材料や熱可塑性エラストマ材料等のエラストマ材料からなる一体成形品にて構成されており、その上側部位を与える、下方に向かうに従って次第に大径となる略円錐台形状の取付部20と、該一体成形品の下側部位を構成する、円柱状の接地部22とを有して、成っている。
【0020】
また、この杖先部14にあっては、取付部20の中心部に、上方に向かって開口し、且つ内周面が円筒面とされた、有底の取付穴24が、軸方向に真っ直ぐに延びるように形成されている。更に、この取付穴24は、前記支柱部材10の下端部の外径よりも僅かに小さな内径と、前記接地部22に達する深さを有して、構成されている。かくして、かかる杖先部14の取付穴24内に、支柱部材10の下端部が圧入されることにより、杖先部14が、取付部20において、支柱部材10の下端部に対して固定的に取り付けられるようになっているのである。
【0021】
そして、本実施形態においては、特に、このような杖先部14の取付穴24内に、従来品には見られない特別な衝撃吸収体26が、収容配置されている。
【0022】
より詳細には、衝撃吸収体26は、全体として、杖先部14の取付穴24の内径と略同一か、それよりも僅かに小さな径を有する球状体形状を呈しており、杖先部14を構成する材料よりも高度の低い、軟質で、変形が容易な弾性材料にて形成されている。また、ここでは、特に、かかる衝撃吸収体26を与える弾性材料として、制振性を有する熱可塑性エラストマが、有利に用いられている。即ち、本実施形態においては、衝撃吸収体26が、例えば、制振性を有する熱可塑性エラストマのコンパウンド[(株)クラレ製:ハイブラー]を公知の金型成形により球状体形状に成形することによって得られる成形品にて、構成されているのである。尤も、本発明にあっては、かかる衝撃吸収体26を与える材料としては、杖先部14よりも容易に変形し得る軟質の弾性材料の何れもが適宜に用いられ、例えば、スチレン系、ポリウレタン系、ポリエステル系、ポリアミド系、フッ素ポリマー系、ブレンド系等の各種熱可塑性エラストマの他、HSN、末端変性エラストマ、高ビニルSBR、高ビニルBR、トランスゴム、VCR、SIBR等の中から、適宜に選択されることとなる。
【0023】
そして、そのような衝撃吸収体26が、杖先部14の取付穴24内における、該取付穴24の底面と、該取付穴24内に挿入(圧入)された支柱部材10の下端面との間に介在せしめられた状態で、それら取付穴24の底面と、支柱部材10の下端面と、取付穴24の内周面とに対して、それぞれ部分的に接触し、且つかかる接触部以外では、それらの面との間に空隙28を形成しつつ、移動不能に位置せしめられているのである。
【0024】
かくして、かくの如き構造とされた本実施形態の棒状杖にあっては、その使用者が、把持部12のハンドル部16を把持しつつ、自分の体重を支えるようにして、杖先部14を路面や床面等に接地させた際に、図2に二点鎖線で示される如く、杖先部14が、比較的に小さな量において、外方に膨出するように弾性変形せしめられ、それによって、該杖先部14の接地時に生ずる衝撃が、ある程度吸収され得るようになっている。また、図には明示されてはいないものの、支柱部材10を斜めにした状態で、杖先部14を接地した際にも、該杖先部14の接地部22が、その接地面の路面や床面との接触面積を十分に確保しつつ、傾斜した状態で弾性変形せしめられ、それによって、高度な安定性が得られると共に、路面や床面に対する滑り抵抗も有効に維持されて、優れた滑り止め効果が発揮され得るようになっているのである。しかも、かかる杖先部14が、従来品と同様な硬度を有して構成されているため、従来品と同程度の耐摩耗性が確保されているのである。
【0025】
そして、かかる棒状杖においては、杖先部14の接地時に、上述のように、該杖先部14が弾性変形せしめられる一方で、杖先部14の取付穴24内に収容位置せしめられた、該杖先部14よりも軟質で、変形が容易な、制振性を有する衝撃吸収体26が、杖先部14の弾性変形量よりも大きな変形量で、しかも、制振性に基づいた振動減衰特性を有利に発揮しつつ、弾性変形せしめられるようになっており、それによって、支柱部材10から、かかる衝撃吸収体26を介して杖先部14に伝達される荷重が有利に減少せしめられ、以て、この衝撃吸収体26において、杖先部14の接地時に生ずる衝撃が、より有効に吸収せしめられ得るようになっているのである。
【0026】
このように、本実施形態の棒状杖にあっては、杖先部14を接地せしめた際に生ずる衝撃が、杖先部14における接地部22の弾性変形によってある程度吸収されるのに加えて、衝撃吸収体26の弾性変形によって、更に有効に吸収され得るようになっているため、それらの協働作用にて、杖先部14の接地時に生ずる衝撃が、より一層有利に吸収され得るのであり、それによって、単に、杖先部14をゴム材料にて形成しただけの従来品に比して、より高度な衝撃吸収特性が効果的に発揮され得、以て、杖先部14を接地せしめた際に、支柱部材10の把持部12を把持する使用者に伝わる衝撃力が、極めて有利に小さく為され得るのである。
【0027】
従って、このような本実施形態に係る棒状杖においては、従来品では到底得られない、より十分な緩衝性能が有利に発揮され得、それによって、使用性の向上が更に高いレベルで実現され得ることとなるのである。
【0028】
また、かかる本実施形態の棒状杖にあっては、支柱部材10とその上端部に取り付けられる把持部12が、炭素繊維強化樹脂材料の1種たるカーボン繊維クロス強化樹脂パイプにて構成されているところから、それら支柱部材10と把持部12、ひいては棒状杖の全体において、優れた機械的強度と軽量性とが付与され得、それによって、取扱性と使用耐久性とが、共に効果的に高められ得るのである。
【0029】
さらに、本実施形態の棒状杖においては、衝撃吸収体26が球体状形状を有して構成されて、杖先部14の取付穴24内に、その内面と底面及び該取付穴24内に挿入される支柱部材10の下端面との間に空隙28を形成しつつ、収容位置せしめられているところから、杖先部14の接地時に、かかる衝撃吸収体26が、それらの空隙28内に侵入するようにして、より容易に弾性変形せしめられ得るのであり、その結果、更に一層優れた衝撃吸収性が確保され得るのである。
【0030】
次ぎに、図3には、本発明に従う構造を有する棒状杖の別の例として、前記実施形態に示されるものとは異なる形状の衝撃吸収体30が、杖先部14の取付穴24内に収容配置されてなるものが、示されている。なお、この図3においては、前記実施形態と同様な構造とされた部材及び部位について、前記実施形態を示す図1及び図2と同様な符号を付すことにより、その詳細な説明は、省略した。
【0031】
すなわち、かかる図3からも明らかなように、本実施形態では、衝撃吸収体30が、全体として、杖先部14の取付穴24の内径と略同一か、それよりも僅かに小さな外径を有する、円環体の1種たる円筒体形状を呈している。また、この衝撃吸収体30は、ここでも、杖先部14よりも軟質で、変形が容易な弾性材料である、制振性を有する熱可塑性エラストマにて形成されている。
【0032】
そして、そのような衝撃吸収体30が、杖先部14の取付穴24内における、該取付穴24の底面と、該取付穴24内に挿入(圧入)された支柱部材10の下端面との間に介在せしめられた状態で、それら取付穴24の底面と支柱部材10の下端面とに対して、高さ方向の両端面の全面をそれぞれ接触させ、且つ取付穴24の内周面に、側面の全面を接触させつつ、移動不能に位置せしめられているのである。
【0033】
これによって、本実施形態の棒状杖にあっては、その使用者が、把持部12のハンドル部16を把持しつつ、自分の体重を支えるようにして、杖先部14を路面や床面等に接地させた際に、図3に二点鎖線で示される如く、杖先部14が、前記実施形態と同様に、比較的に小さな量で、外方に膨出するように弾性変形せしめられることにより、杖先部14の接地時に生ずる衝撃がある程度吸収され得るのであり、また、支柱部材10を斜めにした状態で、杖先部14を接地した際にも、高度な安定性と優れた滑り止め効果とが、十分に享受され得、更には、杖先部14が従来品と同様な硬度を有していることによって、十分な耐摩耗性が発揮され得るようになっているのである。
【0034】
そして、かかる棒状杖においては、杖先部14の接地時に、該杖先部14がある程度弾性変形せしめられる一方で、杖先部14の取付穴24内に収容位置せしめられた、該杖先部14よりも軟質で、変形が容易な、制振性を有する衝撃吸収体26が、その内孔内に、円筒体の側壁部を膨出させるようにして、杖先部14の弾性変形量よりも大きな変形量で、しかも、制振性に基づいた振動減衰特性を有利に発揮しつつ、より容易に弾性変形せしめられるようになっており、それによって、支柱部材10から衝撃吸収体26を介して杖先部14に伝達される荷重が有利に減少せしめられ、以て、この衝撃吸収体26において、杖先部14の接地時に生ずる衝撃が、より有効に吸収せしめられ得るようになっているのである。
【0035】
従って、このような本実施形態の棒状杖にあっても、杖先部14の弾性変形による衝撃吸収作用と、衝撃吸収体26の弾性変形による更に有効な衝撃吸収作用とが相俟って、単に、杖先部14がゴム材料にて構成されてなる従来品に比して、より高度な衝撃吸収特性が効果的に発揮され得るのであり、その結果として、前記実施形態と同様に、従来品では到底得られない、より十分な緩衝性能が有利に発揮され得て、使用性の向上が更に高いレベルで実現され得ることとなるのである。
【0036】
以上、本発明の具体的な構成について詳述してきたが、これはあくまでも例示に過ぎないものであって、本発明は、上記の記載によって、何等の制約をも受けるものではない。
【0037】
例えば、前記実施形態では、把持部12が、支柱部材10と別部材にて構成されて、該支柱部材10の上端部に対して嵌合されて、固着されていたが、かかる把持部12と支柱部材10とを一体成形することにより、把持部12を、支柱部材10の上端部に設けても良いのである。
【0038】
また、前記実施形態では、衝撃吸収体26,30が、制振性を有する熱可塑性エラストマにて形成されていたが、この衝撃吸収体26,30の形成材料は、杖先部14よりも軟質で、変形が容易な弾性材料であれば、特に限定されるものではなく、かかる条件を満たす各種のゴム材料やエラストマ材料等が、適宜に採用され得るのである。
【0039】
さらに、そのような衝撃吸収体26,30の形状も、前記実施形態に示されるものに、何等限定されるものでではなく、杖先部14の取付穴24内における、該取付穴24の底面と、該取付穴24内に挿入される支柱部材10の下端面との間に介在せしめられ得るものであれば、それら両面間における取付穴24の内部空間に対応した形状や、球状体形状及び円筒体(円環体)形状以外で、該両面と取付穴の内周面との間や衝撃吸収体の内部に適当な空隙が形成せしめられるような形状等が、適宜に採用され得るのであり、また、その配設個数も、複数であっても、何等差し支えないのである。
【0040】
更にまた、かかる衝撃吸収体26,30を、発泡体等にて構成しても良く、そうすることによって、より柔軟で、且つ容易な変形性が得られて、衝撃吸収体において、更に一層十分な衝撃吸収性が確保され得るのである。
【0041】
加えて、前記実施形態では、本発明を棒状杖に適用したものの具体例が示されていたが、本発明は、その他、松葉杖や多脚杖等、高齢者や障害者、或いは負傷者等によって使用される各種の杖の何れに対しても有利に適用され得るものであることは、勿論である。
【0042】
その他、一々列挙はしないが、本発明は、当業者の知識に基づいて種々なる変更、修正、改良等を加えた態様において実施され得るものであり、また、そのような実施態様が、本発明の趣旨を逸脱しない限り、何れも、本発明の範囲内に含まれるものであることは、言うまでもないところである。
【0043】
【発明の効果】
以上の説明からも明らかなように、本発明に従う、衝撃吸収性に優れた杖にあっては、従来品では到底得られない、より十分な緩衝性能が有利に発揮され得、それによって、例えばリウマチ患者等、少しの衝撃でも大きな痛みを感じる傷病者等も、可及的に小さな負担で使用が可能となるのであり、その結果として、従来品を使用出来なかった者が使用可能となるといった、極めて優れた使用性が、効果的に発揮され得ることとなるのである。

【Technical field】
The present invention relates to a cane used by an elderly person, a disabled person, an injured person, and the like, and more particularly, to a novel structure of a cane that is improved so that excellent shock absorption can be exhibited.
[0002]
[Background]
In general, elderly people, persons with disabilities, or injured persons who require assistance in daily life, such as stick sticks or wands to support their weight when standing up or walking Various canes such as crutches and multi-legged canes are used.
[0003]
By the way, these various wands are usually provided with a gripping portion to be gripped by the user at the upper end portion of the longitudinal support member, and attached to the lower end portion is a wand tip portion that is grounded during use. The structure is made. In general, the tip of the cane is made of an elastomer member (including a rubber member) having excellent slip resistance, so that the tip of the cane can be used when used on the road surface or on the floor. It can be elastically deformed to some extent while exhibiting sliding resistance against the floor and the floor, etc., and can be prevented from slipping on the road surface and floor, and the impact caused by the contact between the cane tip and the road surface and floor can be reduced. It has become.
[0004]
However, the elastomer cane tip attached to such a conventional cane is formed using a material having a relatively high hardness in order to prevent a decrease in wear resistance. It was inevitable that the cane to which the tip of the cane was attached would be inadequate in buffer performance.
[0005]
Therefore, in such a conventional cane, for example, as a cane used by patients with rheumatism who feel great pain even with a slight impact, and other victims, etc., it could not be provided at all, In that respect, there was much room for improvement.
[0006]
[Solution]
Here, the present invention has been made in the background as described above, and the problem to be solved is that a sufficient buffering performance can be exhibited, so that even a little impact causes a great pain. An object of the present invention is to provide a cane excellent in shock absorption that can be used with as little burden as possible even by a victim who feels it.
[0007]
[Solution]
In the present invention, in order to solve such a problem, a grip portion to be gripped by the user is provided at the upper end portion of the long column member, while the lower end portion is grounded at the time of use. In the cane to which the cane tip portion is attached, the cane tip portion is constituted by an elastomer member having a bottomed attachment hole into which the lower end portion of the support member is inserted, and the elastomer is provided in the attachment hole. A shock absorber made of an elastic material that is softer than the member and easily deformed is accommodated so that the shock absorber is interposed between the lower end of the support member and the bottom surface of the mounting hole. The gist of the cane excellent in shock absorption, characterized by this fact.
[0008]
In such a cane excellent in shock absorption according to the present invention, since the tip of the cane that is attached to the lower end of the support member and is grounded during use is composed of an elastomer member, such a cane The impact generated when the tip is grounded can be absorbed to some extent by the elastic deformation of the tip of the cane. In addition, in the mounting hole into which the support member of such a cane tip is inserted, between the lower end of the support member and the bottom surface of the attachment hole, softer than the elastomer member constituting the cane tip, Since the shock absorber made of an easily deformable elastic material is interposed, when the tip of the cane is grounded, the shock absorber is more easily elastically deformed with a larger deformation amount than the tip of the cane. Thus, the load transmitted from the support member to the tip of the wand via the shock absorber can be advantageously reduced, and the impact generated when the tip of the wand touches down can be reduced. By elastic deformation, it can be absorbed more effectively.
[0009]
Therefore, in the cane excellent in shock absorption according to the present invention, the shock absorbing action by the elastic deformation of the tip of the cane and the more effective shock absorbing action by the elastic deformation of the shock absorber are combined. Compared to conventional products in which the tip of the cane is only composed of an elastomer member, more advanced shock absorption characteristics can be effectively exhibited, and when the tip of the cane is grounded, The impact force transmitted to the user holding the upper end can be made very advantageously small.
[0010]
Therefore, in such a cane excellent in shock absorption according to the present invention, more sufficient buffering performance that cannot be obtained with the conventional product can be exhibited advantageously, so that even a slight impact such as a rheumatic patient can be achieved. It is possible for a patient or the like who feels a great pain to use it with as little burden as possible. As a result, extremely excellent usability that can be used by those who could not use the conventional product can be effectively exhibited.
[0011]
In addition, according to one of the preferable aspects of the cane excellent in the shock absorption according to this invention, the said support | pillar member is comprised with the pipe which consists of carbon fiber reinforced resin materials. Accordingly, excellent mechanical strength and light weight can be imparted to the support member, and thus the entire cane, so that the durability of use can be effectively enhanced while further improving the usability. It is.
[0012]
According to another advantageous aspect of the cane excellent in shock absorption according to the present invention, the cane tip portion is formed of a rubber product, while the shock absorber has vibration damping properties. It is formed from a thermoplastic elastomer. As a result, it is possible to advantageously exhibit better shock absorbing performance derived from vibration damping characteristics based on vibration damping properties in the shock absorber while ensuring shock absorption at the ground contact portion of the wand tip. Thus, even higher buffer performance can be exhibited, and further improvement in usability can be effectively achieved at a higher level.
[0013]
Furthermore, according to one of the other desirable aspects of the cane excellent in shock absorption according to the present invention, the shock absorber is configured to have a spherical shape or a torus shape. In a cane having such a structure, for example, if a mounting hole into which a support member is inserted is formed in a toroidal shape such as a simple ring shape or a cylindrical shape, A space is formed between the spherical-shaped shock absorber and the inner surface of the mounting hole, or in the inner hole of the torus-shaped shock absorber. Or a shock absorber having a toroidal shape can be more easily elastically deformed by a load transmitted from the support member so that a part of the shock absorber penetrates into the gap. Even better shock absorption can be secured, and the buffer performance and usability can be improved more effectively.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, in order to clarify the present invention more specifically, the configuration of a cane excellent in shock absorption according to the present invention will be described in detail with reference to the drawings.
[0015]
First, FIG. 1 schematically shows a rod-shaped cane as an embodiment of a cane having a structure according to the present invention and excellent in shock absorption in its front form. As can be seen from FIG. 1, the stick cane according to the present embodiment includes a longitudinal support member 10 that provides the main body, a gripping portion 12 provided at the upper end of the support member 10, and the support member 10. It has the cane part 14 attached to the lower end part, and is comprised.
[0016]
And the support | pillar member 10 which comprises the main body of this stick-shaped cane consists of cylindrical pipes made from carbon fiber reinforcement resin, for example, carbon fiber cloth reinforcement resin (refer to Drawing 2). That is, here, for example, a predetermined resin such as an epoxy resin is formed on a plain-woven cloth in which the strut members 10 are bundled in a predetermined number, for example, and each bundle of carbon fiber long fibers is woven vertically and horizontally. The pipe is formed by impregnating the material, and winding the cloth in a cylindrical shape and heat-curing the epoxy resin material impregnated in the cloth.
[0017]
Moreover, the holding part 12 is exhibiting the substantially T-shape as a whole, and consists of the integral pipe product made from carbon fiber cloth reinforcement resin similar to the support | pillar member 10. FIG. In the gripping portion 12, the T-shaped head and legs are respectively formed as a handle portion 16 and a fixing portion 18, and the fixing portion 18 is externally fitted to the upper end portion of the column member 10. The handle portion 16 is configured to be held by the user under the fixed state to the column member 10.
[0018]
In addition, the constituent material of such a grip part 12 and the support | pillar member 10 is not limited to carbon fiber cloth reinforced resin as illustrated at all, and other than metal material such as aluminum alloy, wood, or carbon fiber cloth reinforced resin The carbon fiber reinforced resin may be a resin material other than the carbon fiber reinforced resin. Further, even when the carbon fiber cloth reinforced resin as exemplified is used, the type of carbon fiber that gives the resin material is not particularly limited, and various types such as polyacrylonitrile type and pitch type are available. Among them, those excellent in mechanical strength can be appropriately selected and used, and further, the type of epoxy resin is not particularly limited as long as it has a solid property at room temperature. Any type can be advantageously employed.
[0019]
On the other hand, as shown in FIG. 2, the cane portion 14 attached to the lower end portion of the column member 10 has a hardness of 50 to 70 ° (a value measured by a Shore A type durometer) similar to that of the conventional product. It has a substantially frustum-shaped mounting portion 20 which is composed of an integrally molded product made of an elastomer material such as a known rubber material or thermoplastic elastomer material, and which gives an upper portion thereof and gradually increases in diameter toward the lower side. And a cylindrical grounding portion 22 that constitutes the lower portion of the integrally molded product.
[0020]
In addition, in the cane tip portion 14, a bottomed mounting hole 24 that opens upward at the center of the mounting portion 20 and has a cylindrical inner peripheral surface is straight in the axial direction. It is formed to extend. Further, the mounting hole 24 is configured to have an inner diameter slightly smaller than the outer diameter of the lower end portion of the column member 10 and a depth reaching the grounding portion 22. Thus, when the lower end portion of the column member 10 is press-fitted into the attachment hole 24 of the cane tip portion 14, the cane tip portion 14 is fixed to the lower end portion of the column member 10 at the attachment portion 20. It can be attached.
[0021]
In the present embodiment, in particular, a special shock absorber 26 that is not found in the conventional product is accommodated in the mounting hole 24 of the cane tip portion 14.
[0022]
More specifically, the shock absorber 26 as a whole has a spherical shape having a diameter that is substantially the same as or slightly smaller than the inner diameter of the mounting hole 24 of the tip portion 14, and the tip portion 14. It is made of an elastic material that is softer and easier to deform. Here, in particular, a thermoplastic elastomer having vibration damping properties is advantageously used as the elastic material for providing the shock absorber 26. That is, in the present embodiment, the shock absorber 26 is formed by molding a compound of thermoplastic elastomer having damping properties [manufactured by Kuraray Co., Ltd .: Hiblar] into a spherical shape by known mold molding. It is comprised by the obtained molded article. However, in the present invention, as the material for providing the shock absorber 26, any soft elastic material that can be more easily deformed than the cane portion 14 is appropriately used. From various thermoplastic elastomers such as polyester, polyester, polyamide, fluoropolymer, and blend, as well as HSN, terminal-modified elastomer, high vinyl SBR, high vinyl BR, trans rubber, VCR, SIBR, etc. Will be selected.
[0023]
And such an impact-absorbing body 26 is formed between the bottom surface of the mounting hole 24 in the mounting hole 24 of the cane portion 14 and the lower end surface of the column member 10 inserted (press-fitted) into the mounting hole 24. In a state of being interposed therebetween, the bottom surface of the mounting hole 24, the lower end surface of the column member 10, and the inner peripheral surface of the mounting hole 24 are partially in contact with each other, and other than the contact portion The gap 28 is formed so as not to move while the gap 28 is formed between them.
[0024]
Thus, in the stick cane according to the present embodiment having such a structure, the user supports his / her weight while holding the handle portion 16 of the grip portion 12 so that the cane tip portion 14 can be supported. 2 is elastically deformed to bulge outward in a relatively small amount, as shown by a two-dot chain line in FIG. Thereby, the impact generated when the cane tip 14 is grounded can be absorbed to some extent. Although not clearly shown in the figure, when the cane portion 14 is grounded in a state where the column member 10 is inclined, the grounding portion 22 of the cane portion 14 is not connected to the road surface of the ground surface. It is elastically deformed in an inclined state while ensuring a sufficient contact area with the floor surface, thereby achieving high stability and effectively maintaining slip resistance against the road surface and floor surface. The anti-slip effect can be exerted. Moreover, since the cane portion 14 is configured to have the same hardness as the conventional product, the same level of wear resistance as that of the conventional product is ensured.
[0025]
In such a rod-shaped cane, when the cane tip part 14 is grounded, the cane tip part 14 is elastically deformed as described above, while being placed in the mounting hole 24 of the cane tip part 14. The shock absorber 26 having vibration damping properties that is softer and easier to deform than the cane tip portion 14 has a deformation amount larger than the elastic deformation amount of the cane tip portion 14 and vibration based on the vibration damping property. It is designed to be elastically deformed while advantageously exhibiting the damping characteristic, whereby the load transmitted from the support member 10 to the cane tip portion 14 via the shock absorber 26 is advantageously reduced. Thus, in this shock absorber 26, the shock generated when the cane portion 14 is grounded can be absorbed more effectively.
[0026]
Thus, in the rod-shaped cane of this embodiment, in addition to the impact generated when the tip of the cane 14 is grounded being absorbed to some extent by the elastic deformation of the grounding portion 22 at the tip of the cane 14, Since the elastic deformation of the shock absorber 26 can be absorbed more effectively, the impact generated when the wand tip 14 is grounded can be absorbed more advantageously by their cooperative action. As a result, a higher level of shock absorbing characteristics can be effectively exhibited as compared with a conventional product in which the cane portion 14 is simply formed of a rubber material, and the cane portion 14 is grounded. In this case, the impact force transmitted to the user gripping the grip portion 12 of the column member 10 can be made extremely advantageously small.
[0027]
Therefore, in such a rod-shaped cane according to this embodiment, a sufficient buffering performance that cannot be obtained with the conventional product can be advantageously exhibited, and thereby the usability can be improved at a higher level. It will be.
[0028]
Moreover, in this stick-shaped cane of this embodiment, the support | pillar member 10 and the holding part 12 attached to the upper end part are comprised by the carbon fiber cloth reinforcement | strengthening resin pipe which is 1 type of a carbon fiber reinforced resin material. Therefore, excellent mechanical strength and light weight can be imparted to the column member 10 and the grip portion 12, and thus the entire stick-shaped cane, thereby effectively improving both handling and durability. It can be done.
[0029]
Further, in the rod-shaped cane of this embodiment, the shock absorber 26 is configured to have a spherical shape, and is inserted into the mounting hole 24 of the cane tip portion 14, its inner and bottom surfaces, and the mounting hole 24. The shock absorber 26 penetrates into the space 28 when the cane 14 is grounded from the place where the space 28 is formed while forming the space 28 with the lower end surface of the support member 10 to be placed. Thus, it can be more easily elastically deformed, and as a result, even better shock absorption can be ensured.
[0030]
Next, in FIG. 3, as another example of a rod-shaped cane having a structure according to the present invention, an impact absorber 30 having a shape different from that shown in the above embodiment is placed in the mounting hole 24 of the cane tip portion 14. What is housed is shown. In FIG. 3, members and parts having the same structure as in the above embodiment are given the same reference numerals as those in FIGS. 1 and 2 showing the above embodiment, and detailed description thereof is omitted. .
[0031]
That is, as apparent from FIG. 3, in this embodiment, the shock absorber 30 as a whole has an outer diameter that is substantially the same as or slightly smaller than the inner diameter of the mounting hole 24 of the cane portion 14. It has a cylindrical shape that is a kind of torus. The shock absorber 30 is also made of a thermoplastic elastomer having vibration damping properties, which is an elastic material that is softer than the cane portion 14 and easily deformed.
[0032]
And such an impact-absorbing body 30 is formed between the bottom surface of the mounting hole 24 in the mounting hole 24 of the cane portion 14 and the lower end surface of the column member 10 inserted (press-fitted) into the mounting hole 24. In the state of being interposed therebetween, the entire surface of both end surfaces in the height direction are brought into contact with the bottom surface of the mounting hole 24 and the lower end surface of the column member 10, respectively, and the inner peripheral surface of the mounting hole 24 is It is positioned so as to be immovable while contacting the entire side surface.
[0033]
As a result, in the stick cane according to the present embodiment, the user supports the weight of the user while holding the handle portion 16 of the grip portion 12 so that the cane tip portion 14 is placed on the road surface, the floor surface, or the like. 3, as shown by a two-dot chain line in FIG. 3, the cane tip portion 14 is elastically deformed so as to bulge outward in a relatively small amount as in the above-described embodiment. Thus, the impact generated when the cane tip 14 is grounded can be absorbed to some extent, and even when the cane tip 14 is grounded with the column member 10 being inclined, high stability and superiority are achieved. The anti-slip effect can be fully enjoyed. Furthermore, since the tip portion 14 has the same hardness as the conventional product, sufficient wear resistance can be exhibited. .
[0034]
In such a rod-shaped cane, when the cane tip part 14 is grounded, the cane tip part 14 is elastically deformed to some extent, while the cane tip part is accommodated in the mounting hole 24 of the cane tip part 14. The shock absorber 26, which is softer than 14 and easy to deform, has vibration damping properties, causes the side wall portion of the cylindrical body to bulge into the inner hole, and the amount of elastic deformation of the cane portion 14 In addition, it is possible to elastically deform more easily, while advantageously exhibiting vibration damping characteristics based on vibration damping properties with a large amount of deformation, and thereby, from the strut member 10 via the shock absorber 26. Thus, the load transmitted to the cane portion 14 is advantageously reduced, so that the impact absorbing body 26 can absorb the impact generated when the cane portion 14 contacts the ground more effectively. It is.
[0035]
Therefore, even in such a rod-like cane of this embodiment, the impact absorbing action due to the elastic deformation of the cane portion 14 and the more effective shock absorbing action due to the elastic deformation of the shock absorber 26 are combined. As compared with the conventional product in which the cane tip portion 14 is simply made of a rubber material, a higher level of impact absorption characteristics can be effectively exhibited. As a result, more sufficient buffering performance, which cannot be obtained with a product, can be advantageously exhibited, and improvement in usability can be realized at a higher level.

[0038]
In the above-described embodiment, the shock absorbers 26 and 30 are formed of a thermoplastic elastomer having vibration damping properties. However, the material for forming the shock absorbers 26 and 30 is softer than the cane portion 14. Thus, the elastic material is not particularly limited as long as it is easily deformable, and various rubber materials, elastomer materials, and the like that satisfy such conditions can be appropriately employed.
[0039]
Further, the shape of the shock absorbers 26 and 30 is not limited to that shown in the embodiment, and the bottom surface of the mounting hole 24 in the mounting hole 24 of the cane portion 14 is not limited. And a shape corresponding to the internal space of the mounting hole 24 between both surfaces, a spherical body shape, and the like, as long as it can be interposed between the lower end surface of the column member 10 inserted into the mounting hole 24. Other than the cylindrical (annular) shape, a shape or the like in which an appropriate gap is formed between the both surfaces and the inner peripheral surface of the mounting hole or inside the shock absorber can be adopted as appropriate. In addition, even if there are a plurality of arrangements, there is no problem.
[0040]
Furthermore, the shock absorbers 26 and 30 may be made of foam or the like, and by doing so, more flexible and easy deformability can be obtained. It is possible to ensure a sufficient shock absorption.
[0041]
In addition, in the above-described embodiment, specific examples of the present invention applied to a stick cane have been shown. Of course, it can be advantageously applied to any of the various canes used.
[0042]
