Description

【０００１】
【発明の属する技術分野】
本発明は、雪の低山、雪渓又は滑りやすい泥道を歩行する際に登山靴に取付けて使用するのに適当な簡易アイゼンに関するものである。
【０００２】
【従来の技術】
アイゼンは、云うまでもなく、雪山の氷雪上を安全に歩行するために登山靴に取付けて使用するものであるが、厳しい冬山登山ばかりでなく、雪の低山、夏の雪渓、或いは滑りやすい泥道でもその滑落防止のために有効である。そしてこのような軽登山で使用する簡易アイゼンには非常に多くのそれが提供されているが、いずれも、その着脱が厄介であったり、携帯に不便であったり、或いは靴の種類によっては装着が不可であったり、若しくは歩行中に前後若しくは左右にずれたりし易い等の問題のいずれかを抱えており、満足のいくものが提供されているとは言い難かった。
【０００３】
そこで本発明者はこれらの問題点を解決すべく新たな簡易アイゼン（特許文献１）を提案した。
これは、「相互にフレキシブルなジョイント部材で結合され、各々に複数のスパイクを備えたフロントプレート及びヒールプレートと、これらを登山靴に装着するためのバンド手段とを備えたアイゼンに於いて、
前記スパイクを、フロントプレート及びヒールプレートの双方の下方に突き出す複数の突起であって、各々の上部から、該フロントプレート及び該ヒールプレートの上方に立ち上がる横ズレ防止ピンを一体に備えた突起に構成し、
前記バンド手段を、
前記ヒールプレートの両側から各々立ち上げた後部立ち上げ鎖に支持される後部抱持バンドであって、靴の後部を抱持状態に支持する後部抱持バンドと、
前記フロントプレートの両側から各々二本ずつ立ち上げた前部立ち上げ鎖の内、一側の二つの前部立ち上げ鎖に結合し、他側の二つの前部立ち上げ鎖に着脱自在に結合する靴の前上部抱持バンドであって、その前部立ち上げ鎖と結合した側から後方に延長結合片を延長し、同じ側で前記後部抱持バンドから延長した延長結合片に結合した前上部抱持バンドと、
両側の各二つの前部立ち上げ鎖の内、前部側の前部立ち上げ鎖の上部間に配する靴前部抱え用の前部抱え鎖と、
前記前上部抱持バンドからその延長結合片と対称に延長した着脱延長片であって、前記後部抱持バンドからその延長結合片と対称に延長した着脱延長片に着脱自在に結合する着脱延長片とで構成し、
かつ前記バンド手段を構成する後部抱持バンド、前上部抱持バンド、該後部抱持バンド及び該前上部抱持バンドの各延長結合片並びに各着脱延長片を弾性材で構成した簡易アイゼン」である。
【０００４】
このような簡易アイゼンは、先に述べたそれ以前のアイゼンと比べれば、その着脱も簡単であり、携帯にも不都合がなく、かつ靴の種類を問わず装着可能であり、加えて歩行中に前後若しくは左右にずれたりするような問題もなく優れたものであるということができる。
【０００５】
しかしその後の更なる検討により、雪が部分的に消えたガレ場、或いは木の枝等が錯綜した灌木帯その他のエリアをこれを外さずに歩いた場合に、バンド手段として使用する弾性材を、その構成上、板状ゴム材を打ち抜いたような部材で構成せざるを得ない関係上、それが損傷する虞を否定し得ないことが明らかになった。
【０００６】
またこの簡易アイゼンは、それ以前のアイゼンと比べれば、非常に装着の容易なものではあるが、その装着に際し、登山靴でそのヒールプレート及びフロントプレートを踏んだ状態で、結合用の複数のバンド部材を外側から内側に回してそれらの各先端のフックを内側の部材のリングに掛けるように操作すべきものであるため、各バンド部材の弾力により外側又は内側に引張られがちとなり内外バランス良く装着するのがやや面倒で、使い勝手の点で若干改善の余地がない訳でもないことが分かった。

【発明が解決しようとする課題】
本発明は、以上の従来技術の問題点を解決し、靴の種類を問わずに簡単に、かつ左右のバランス良く装着でき、更に靴の踵側上部は堅くしっかりと係止可能であるとともに、靴の前甲部は必要以上に締付けないように配慮し、加えて安全な歩行を確保するため歩行中は靴に確実に固定されるものである一方で、使用部材の内、特に弾性材について損傷の危険性を低くした、携帯にも便利な簡易アイゼンを提供することを解決の課題とするものである。
【０００９】
【課題を解決するための手段】
本発明の１は、相互にフレキシブルなジョイント部材で結合され、かつ各々に複数のスパイクを備えたフロントプレート及びヒールプレートと、これらを登山靴に装着するためのバンド手段とを備えたアイゼンに於いて、
前記スパイクを、フロントプレート及びヒールプレートの双方の下方に突き出す複数の突起であって、各々の上部から、該フロントプレート及び該ヒールプレートの上方に立ち上がる横ズレ防止ピンを一体に備えた突起に構成し、
前記バンド手段を、
両端を各々前記ヒールプレートの左右側部から立ち上げ、その途中で装着する登山靴の踵上部を抱える踵上部抱持鎖であって、その途中にスライド移動自在に二つの被吊上部材を配した踵上部抱持鎖と、
両端を各々前記フロントプレートの左右前側部から立ち上げ、中間部で、装着する登山靴の爪先部分を抱えるとともに、該中間部とその両側の立ち上げ部分との各境界を被吊上部に構成した爪先部抱持鎖と、
各々前記フロントプレートの左右後側部から立ち上げ、各上端を被吊上部に構成した左右１対の側部抱持鎖と、
左右両側の前側部と後側部に各一対の吊上補助孔を開口し、装着する登山靴の前甲部に配置して使用される吊上補助片と、
係止孔及び切欠付係止孔をその上部に並設配置し、前者に後記弾性バンド紐の一方の末端の拡大部を抜け止め状態に結合し、後者に後記弾性バンド紐の他方の末端の拡大部を着脱自在に結合可能とした紐端留め片であって、その下部に切欠付係止孔を配置し、この簡易アイゼンを登山靴に装着した場合に、甲側足首部に位置して、該切欠付係止孔に、該登山靴の両側を通過する該弾性バンド紐の途中の各々を係脱自在に係合可能に構成した紐端留め片と、
保護被覆を備えた前記弾性バンド紐であって、その長さ方向中間部を前記吊上補助片の前部中央上に位置させ、その両側への延長部分の途中を各々該吊上補助片の対応する前側部の一対の吊上補助孔の前部側のそれに挿入して垂下させるとともに各々前記爪先部抱持鎖の対応する被吊上部に貫通係止させた上で各々後部側のそれに挿入して該吊上補助片上に引き出し、更に各々を該吊上補助片の対応する後側部の一対の吊上補助孔の前部側のそれに挿入して垂下させるとともに各々対応する側の前記側部抱持鎖の上端の被吊上部に貫通係止させた上で各々後部側のそれに挿入して該吊上補助片上に引き出し、かつ各々を後方に延長させ、更にそれらの中間の拡大部の後方を前記ヒールプレートの踵上部抱持鎖の途中に配した二つの被吊上部材の対応する側のそれに貫通させ、更にその一方の延長部の末端の拡大部直前を前記紐端留め片の係止孔に貫通係止させ、その一方の延長部及びその他方の延長部を、この簡易アイゼンを登山靴に装着した場合に、該登山靴の甲側足首部に回し、他方の延長部の末端の拡大部の直前を一方の延長部の末端に係止している紐端留め片の切欠付係止孔に着脱自在に結合した状態で、該登山靴の両側を通過している該弾性バンド紐の途中を各々該紐端留め片の下部に形成してある切欠付係止孔に貫通係止させ得るようにした弾性バンド紐とで構成した簡易アイゼンである。
【００１０】
従って本発明の１の簡易アイゼンによれば、携帯が容易であり、かつ必要な場合には登山靴に容易に着脱容易に装着できるものでもある。またその装着は、バンド手段の弾力性を必要とする構成要素として保護被覆を備えた弾性バンド紐を採用したため、確実に保持できるものともなっている。これは、該弾性バンド紐が保護被覆による保護を確保しているものであるためであり、更にはそれが紐であって外部の様々なものに接触する面積が狭く、しかもそれが登山靴への装着時にその足首や甲の上部中央のように該登山靴の中央部に配置されるように構成したものであるため、該弾性バンド紐が歩行時に雪氷の消えた岩場の岩や灌木帯の木の根等に接触してこれらによる損傷を受ける可能性が極めて低いものとなっているからである。
【００１１】
更に該弾性バンド紐は軽量で嵩張らない一本のフレキシブルな部材なので予備品としての携帯にも都合が良く、仮に損傷した場合でも容易に交換可能であるため一層高い実質的な安全性の向上が図れる。
【００１２】
また本発明の１の簡易アイゼンによれば、そのヒールプレートを登山靴の踵部の下に、フロントプレートを爪先部の下に、各々位置させ、吊上補助片を登山靴の甲の前部に載せ、その吊上補助片及びその各一対の吊上補助孔から垂下した弾性バンド紐の該当部分と被吊上部とで係止する吊上対象の前記爪先部抱持鎖等に囲まれた空間の中に後方から登山靴の爪先部を挿入し、弾性バンド紐を左右均等に前方から後方に引張り、その途中に設けた各拡大部の後方を両側の対応する被吊上部材の上部に貫通させるとともに、相互を交差させて引っ張り、両側の被吊上部材を当接させ、この状態で更に両側の弾性バンド紐を該登山靴の前方に廻し、これによって踵上部抱持鎖を登山靴の踵上部に持上げ、加えて一方の弾性バンド紐の先端拡大部が抜け止め状態に係止されている紐端留め片に、もう一方の係止されていない弾性バンド紐の先端拡大部をその上部の切欠付係止孔に係止させる。こうして弾性バンド紐の両側が左右均等に引かれて締められるため、その装着は登山靴に対してバランス良く良好に行われ得ることとなるものである。
【００１３】
続いて、登山靴の両側で紐端留め片の下側近傍を通過する弾性バンド紐の途中をそれぞれ中央側に引き寄せ紐端留め片の下部に配置された切欠付係止孔に貫通係合させる。これで登山靴への装着は完了であり、極めて簡単に装着操作ができるものである。
【００１４】
なおこの状態で弾性バンド紐の各々の足首前方の部位相互は構成上弾力的にバランスが取れているため、簡単にその係合操作を行うことができる。しかもこれにより弾性バンド紐は、登山靴の甲の上部中央及び足首周りにのみ配置されることになるため、雪の消えた岩場や木の根や灌木類の突出するような道を歩く際にもこれがそれらに引っかかる等により損傷を受ける可能性が非常に低くなるものである。
【００１５】
なお、前記弾性バンド紐は、その抜け止め用の拡大部の後方が、前記踵上部抱持鎖の途中に配した被吊上部材の上部を貫通することとしたため、該弾性バンド紐の後方の延長部をいくら強く引いても該拡大部より前方の部分が該被吊上部材を通過して後方に移動するようなことはない。また二つの被吊り上げ部材は、前記弾性バンド紐を、上記のように強く引いた場合に、相互が当接し合って、前記踵上部抱持鎖の中間部付近に停止状態となる。
【００１６】
そのため、これによって該拡大部から前方の部分が必要以上に締め付けられるようなことはなくなり、前記踵上部抱持鎖による登山靴の踵上部の抱持状態を強い締め付け状態にしようとして、該拡大部より後方の長さを短くして、足首の前方側で、その両末端を前記紐端留め片に係止したとしても、登山靴の甲側に位置する該弾性バンド紐の途中の部分がその影響を受けて強く締め付けられるような虞はない。
【００１７】
また本発明の１の簡易アイゼンは、前記ヒールプレート及び前記フロントプレートの下部にスパイクが突出しており、これによって氷雪上や泥道に於ける滑り止めの効果が十分発揮できるものであるのは云うまでもないが、該ヒールプレート及び該フロントプレートの上面に横ズレ防止ピンを立ち上げているので、歩行中にこれらが前後又は左右にずれるような虞がない。それ故、一層歩行の安全性が確保できる。
【００１８】
本発明の２は、本発明の１の簡易アイゼンに於いて、前記踵上部抱持鎖の途中にスライド移動自在に配した二つの被吊上部材を、各々その下部に設けられ前記踵上部抱持鎖を貫通させる貫通孔と、その上部に設けられ前記弾性バンド紐の各一方の途中の中間拡大部の後方を貫通させる係止孔とを備えたものに構成したものである。
【００１９】
従って本発明の２の簡易アイゼンによれば、二つの被吊上部材が、踵上部抱持鎖上をこれを貫通させた貫通孔によってスライド自在に移動可能となっているため、この簡易アイゼンを登山靴に装着した際に、該被吊上部材が、該登山靴の踵上部に移動して相互に当接し合うこととなり、無理なく、踵上部抱持鎖の踵上部への引き上げとその位置決めとが行われ得るものとなるものである。
【００２０】
本発明の３は、本発明の１又は２の簡易アイゼンに於いて、前記拡大部を、前記弾性バンド紐の該当する部位に結び部を形成し、該弾性バンド紐を係止球の貫通孔に貫通させ、その結び部を該貫通孔の大径部に嵌入させ、かつ該結び部から延長する部位を小径部から抜け出るようにして構成したものである。
【００２１】
従って本発明の３の簡易アイゼンによれば、前記拡大部が前記被吊上部や紐端留め片の係止孔又は切欠付係止孔に確実に係止できるものに構成できるとともに、その外観も優れたものとなる利点を有する。
【００２２】
本発明の４は、本発明の１、２又は３の簡易アイゼンに於いて、前記踵上部抱持鎖の両端近傍に、登山靴への装着時にその踵上部で靴底部周縁の上部に係止し得るように係止バー部材の両端を取り付けたものである。
【００２３】
前記係止バー部材は、登山靴の踵上部で若干周囲に突出する靴底部周縁に確実に係止すべきものである関係上、ある程度の剛性があることが必要である。そのような観点から適当な太さの金属棒等を採用することができる。例えば、真鍮やステンレススチール等の棒材を採用することができる。また該係止バー部材は、装着する登山靴の靴底部周縁の上部に於ける形状に一致する円弧状であるのが好ましいが、それほど長いものではないので、直線状であっても差し支えない。またその材質として金属部材を採用した場合は、多くの場合は、装着中に靴の後部形状になじんで対応する円弧状になってしまうので好都合である。
【００２４】
また前記係止バー部材は、前記のように、その両端を前記踵上部抱持鎖の両端近傍に取り付けるものであるが、両端近傍に於けるその取付位置は、前記のように、これを登山靴に装着した際に、該係止バー部材がその靴底部周縁の上部に良好に係止し得る部位である。また該踵上部抱持鎖と該係止バー部材の端部との取付は、例えば、該係止バー部材の両端部を各々フック状に加工してこれらを直接に該踵上部抱持鎖の該当部位に係止することにより、或いは該係止バー部材の両端部にＳ字環や鎖部材その他、必要な強度を備えた部材を結合してこれらを介して接続することにより行うことが可能である。
【００２５】
従って本発明の４の簡易アイゼンによれば、登山靴への装着時に、該登山靴の踵上部で靴底部周縁の上部に係止バー部材が係止することとなるため、該係止バー部材及び踵上部抱持鎖の両側部分によって、より一層確実に前記ヒールプレートが固定されることになる。そのため歩行中に該ヒールプレートが横ズレ、縦ズレ又はその他の方向へのズレを生じることがなくなり、一層安全な歩行を確保することができることとなる。
【００２６】
【発明の実施の形態】
本発明の実施の形態を、図面を参照しつつ実施例により詳細に説明する。
図１は装着準備状態にある一実施例の簡易アイゼンの概略斜視図、図２は登山靴の甲に配置される吊上補助片の拡大平面図、図３は端部係止球と組合せて弾性バンド紐の両端部を連結するための紐端留め片の拡大平面図、図４は弾性バンド紐に拡大部を構成するための係止球の拡大断面図、図５は踵上部抱持鎖を弾性バンド紐で吊上げるための踵部吊上補助片（被吊上部材）の拡大概略斜視図、図６は一実施例の簡易アイゼンを装着した登山靴の概略斜視図、図７は一実施例の簡易アイゼンを装着した登山靴の概略背面図である。
【００２７】
＜実施例＞
この実施例の簡易アイゼンは、図１に示すように、フロントプレート１と、ヒールプレート２と、これらを結合するジョイント鎖（ジョイント部材）３と、上記フロントプレート１及び上記ヒールプレート２に配したスパイク４、４…及び横ズレ防止ピン５、５…と、登山靴Ｓに装着するためのバンド手段とで構成したものである。
【００２８】
前記フロントプレート１は登山靴Ｓの爪先付近から土踏まず手前付近に配して使用されるもので、金属板材、この実施例では、ステンレススチールの板材を打ち抜いて形成したものである。図１に示すように、その内部の二個所を打ち抜き開口させて軽量化を図っている。前記ヒールプレート２は、登山靴Ｓの踵部の位置に配して使用されるもので、前記フロントプレート１と同様にステンレススチールの板材を打ち抜いて形成したものである。
【００２９】
これらのフロントプレート１及びヒールプレート２は、図１に示すように、相互を互いに近接する側の中央部分で前記ジョイント鎖３により結合している。該ジョイント鎖３の長さは、登山靴Ｓのサイズに合わせて適切な長さに設定しておくものとする。この長さを調節可能としても良いが、登山靴Ｓのサイズに合わせて数種用意しておく方が適当である。
【００３０】
前記フロントプレート１及びヒールプレート２の両側部にはその下方に突出する複数のスパイク４、４…を連設する。この実施例では、図１に示すように、該フロントプレート１の両側部には各々３本のスパイク４、４、４を垂下突設し、該ヒールプレート２の両側部には各々２本のスパイク４、４を垂下突設する。上記各スパイク４、４…は、各々フロントプレート１及びヒールプレート２の該当部位に開口した固定孔に下方から下向き突起部材を挿入し、上方に突き抜けた部位の外周大径部をカシメて固定しているものである。即ち、こうして下方に突出した突起がスパイク４、４…を構成するものである。またこのスパイク４、４…は、上方に突き抜けた部位の外周拡大部をカシメて固定するものであり、該外周拡大部の中心には小さな突起が形成してあり、これが横ズレ防止ピン５、５…となる。
【００３１】
前記バンド手段は、図１に示すように、基本的に、前記ヒールプレート２に位置して装着する登山靴Ｓの踵上部を抱える踵上部抱持鎖６と、該踵上部抱持鎖６の両端近傍に、登山靴Ｓへの装着時に靴底部Ｓ１周縁の上部に係止し得るように、その両端を取り付けた係止バー部材１４と、前記フロントプレート１の前部に位置して装着する登山靴Ｓの爪先部分を抱える爪先部抱持鎖８と、各々前記フロントプレート１の左右後側部から立ち上げた左右１対の側部抱持鎖７、７と、左右両側の前側部と後側部に各一対の吊上補助孔を開口し、装着する登山靴Ｓの甲部に配置して使用される吊上補助片１０と、フロントプレート１から立ち上がった爪先部抱持鎖８及び側部抱持鎖７、７を装着する登山靴Ｓの足先側を抱持させるべく吊上支持し、ヒールプレート２から立ち上がった踵上部抱持鎖６を吊上げつつ該登山靴Ｓの踵上部に抱持させ、かつ該登山靴Ｓの足首に回して固定する、保護被覆を備えた弾性バンド紐９と、該弾性バンド紐９の両端の結合固定のため及びこの簡易アイゼンの登山靴への装着時に、その両側を通過する弾性バンド紐９の該当する部分を該登山靴の中央ライン側に引き寄せるための紐端留め片１２と、前記弾性バンド紐９で踵上部抱持鎖６を持上げるための１対の踵部吊上補助片（被吊上部材）１３、１３とで構成したものである。
【００３２】
前記踵上部抱持鎖６は、図１に示すように、その両端を各々前記ヒールプレート２の左右側部から立ち上げたもので、登山靴Ｓへの装着状態で、そのほぼ中央部を一対の踵部吊上補助片１３、１３により引き上げられ、両側の立ち上げ部分が装着した登山靴Ｓの踵上部を両側から抱える状態となるものである。
【００３３】
該一対の踵部吊上補助片１３、１３は、特に図５に示すように、合成樹脂で成形された直方体状の部材で、その下部に上記踵上部抱持鎖６をスライド移動自在に貫通させる鎖貫通孔１３ｂが開口してあり、かつその上部に前記弾性バンド紐９を貫通させる紐通過孔１３ａが開口してあるものである。
【００３４】
前記係止バー部材１４は、図１及び図７に示すように、対象の登山靴Ｓの幅より僅かに短い寸法の真鍮製の棒材であり、その両端に配した各二連のリング１４ａ、１４ａを介して前記踵上部抱持鎖６の両端から所定長さ分だけ中央よりの位置に結合したものである。該係止バー部材１４は、上記の構成に代えて、これをもう少し長く構成すると共に、その両端にフックを形成し、該踵上部抱持鎖６の該当部位に直接結合しても良い。
【００３５】
なお前記所定長さ分は、特に図７に示すように、登山靴Ｓへの装着の際にヒールプレート２を靴底部Ｓ１の下部の所定の位置に配し、かつ前記係止バー部材１４を靴底部Ｓ１外縁の上部に係止させた状態の場合に於いて、該ヒールプレート２の側部から靴底部Ｓ１の外縁上部までの長さである。従って、前記係止バー部材１４は、登山靴Ｓへの上記装着状態で、図７に示すように、その靴底部Ｓ１外縁上部に位置する踵上部抱持鎖６の各部位に前記両側の二連のリング１４ａ、１４ａの外端を結合することにより、これを介して該踵上部抱持鎖６に取り付けたものである。
【００３６】
前記爪先部抱持鎖８は、図１及び図６に示すように、両端を各々前記フロントプレート１の左右前側部から立ち上げる立ち上げ鎖部８ａ、８ｂと、これらに連続する中間部であり、装着する登山靴Ｓの爪先部分を抱える爪先抱持鎖部８ｅと、該爪先抱持鎖部８ｅとその両側に連続する立ち上げ鎖部８ａ、８ｂとの各境界に配した被吊上環（被吊上部）８ｃ、８ｄとで構成する。
【００３７】
前記側部抱持鎖７、７は、図１に示すように、各々前記フロントプレート１の左右後側部から立ち上げた立ち上げ鎖部７ｃ、７ｃと、それらの各上端に配した被吊上環（被吊上部）７ａ、７ｂ（被吊上環７ｂは図面中に表れていない）とで構成する。
【００３８】
前記吊上補助片１０は、図１、図２及び図６に示すように、合成樹脂製の板材で構成したものであり、左右両側の前側部と後側部に各々前後方向に並べた一対の吊上補助孔１０ａ、１０ｂ、１０ｃ、１０ｄ、１０ｅ、１０ｆ、１０ｇ、１０ｈを開口したものである。これらの吊上補助孔１０ａ、１０ｂ、１０ｃ、１０ｄ、１０ｅ、１０ｆ、１０ｇ、１０ｈは、後述するように、前記弾性バンド紐９が挿通されることになる。また、図２に示すように、その上面には、一つの吊上補助孔から隣接の吊上補助孔へと亘る弾性バンド紐９を半ば埋設する案内溝、例えば、吊上補助孔１０ａと１０ｅを繋ぐ案内溝１０ｉが刻まれている。
【００３９】
なお、上端に刻まれた案内溝１０ｌ、１０ｍは吊上補助孔１０ｄ、１０ｈから紐端留め片１２に延びる弾性バンド紐９を案内し半埋設させるものである。これらの案内溝には弾性バンド紐９の位置ずれ防止とともに、露出に伴う接触及び損傷を回避する役割もある。
【００４０】
前記弾性バンド紐９は、その弾性材として、この実施例では多数の糸状の合成ゴム材を断面が円柱状になるように束ね合わせ、その外周を伸縮性に富む布で覆って構成したものであり、容易に入手できるものである。
【００４１】
前記弾性バンド紐９は、図１及び図６に示すように、その長さ方向の中間部分を前記吊上補助片１０に係合し、該吊上補助片１０から後方に延長する部分の両末端直前には端部係止球１１ａ、１１ｂを固設し、各々の途中には中間係止球１１ｃ、１１ｄを固設したものである。一方の端部係止球１１ｂの直前の紐部分には、予めこれを係止孔１２ａに貫通させることで紐端留め片１２が取付けてある。
【００４２】
なお、前記弾性バンド紐９の該吊上補助片１０から後方に延びる二つの延長部分の内、該吊上補助片１０から途中の中間係止球１１ｃ、１１ｄまでの間を前後連結部９ｅ、９ｆと称し、該中間係止球１１ｃ、１１ｄから末端までの間を踵側締付部９ｇ、９ｈと称する。後述するように、締付の張力は境界をなす中間係止球１１ｃ、１１ｄの部分で分断されるため、これらの弾性バンド紐９の各部は締付の張力の及ぶ範囲と対応することになり、各部の長さを調整しておけば該当部分のみ所定の強さで締め付けることができる。
【００４３】
前記弾性バンド紐９は、図１及び図６に示すように、その長さ方向の中間部分を中心として、その両側の部分を前記吊上補助片１０の最前部の両側の吊上補助孔１０ａ、１０ｅに各々上方から挿入し、その一方の吊上補助孔１０ａに挿入した側は、下方からこれと対になる後方の吊上補助孔１０ｂに挿入することで、その部位に吊上垂下部９ａを生じさせ、上方に出た部分は更にその後方の吊上補助孔１０ｃに挿入し、下方に出た部分を今度はこれと対になる吊上補助孔１０ｄに挿入することで、その部位に吊上垂下部９ｃを生じさせ、該吊上補助孔１０ｄから上方に出た部分は図２に示す案内溝１０ｌを経由して後方に延長する。
【００４４】
また前記両側の吊上補助孔１０ａ、１０ｅの内、他方の吊上補助孔１０ｅに挿入した側も同様に、図１及び図６に示すように、下方からこれと対になる後方の吊上補助孔１０ｆに挿入することで、その部位に吊上垂下部９ｂを生じさせ、上方に出た部分は更にその後方の吊上補助孔１０ｇに挿入し、下方に出た部分を今度はこれと対になる吊上補助孔１０ｈに挿入することで、その部位に吊上垂下部９ｄを生じさせ、該吊上補助孔１０ｈから上方に出た部分は後方に延長する。
【００４５】
図１及び図６に示すように、前記吊上垂下部９ａ、９ｃ、９ｂ、９ｄの内、吊上垂下部９ａ、９ｂは、これを以上のようにセットする際に、予め、前記フロントプレート１の前両側部から立ち上がった爪先部抱持鎖８の両側の被吊上環８ｃ、８ｄに貫通係止させ、また吊上垂下部９ｃ、９ｄは、これを以上のようにセットする際に、予め、該フロントプレート１の後両側部から各々立ち上げた側部抱持鎖７、７の各々の上端の被吊上環７ａ、７ｂに貫通係止させる。
【００４６】
前記弾性バンド紐９は、前記し、かつ図１及び図６に示すように、その両方の末端直前には端部係止球１１ａ、１１ｂが固設してあり、途中には中間係止球１１ｃ、１１ｄが固設してあるが、これらは、前記吊上補助片１０の各吊上補助孔１０ａ〜１０ｈへの挿入及び前記各吊上環７ａ、７ｂ、８ｃ、８ｄへの貫通係止の後に固設すべきものであることは云うまでもない。
【００４７】
もっとも前記弾性バンド紐９は、該吊上補助片１０から後方に延びる前後連結部９ｅ、９ｆと踵側締付部９ｇ、９ｈとの境界に位置する中間係止球１１ｃ、１１ｄについては、これらを取り付けた後に、各々それらより末端側を、前記ヒールプレート２の踵上部抱持鎖６に配した二つの踵部吊上補助片１３、１３の各紐通過孔１３ａを貫通させ、該中間係止球１１ｃ、１１ｄが各々それらに係止するようにする。これらの取り付けが済んだ後、該当する端部には前記端部係止球１１ａを取り付け、他の該当する端部には、その直前に紐端留め片１２を取り付けた上で、前記端部係止球１１ｂを取り付けるべきことになる。
【００４８】

【００５０】
従ってこの実施例の簡易アイゼンによれば、その登山靴Ｓへの装着が簡単にでき、かつこれを装着して氷雪上や泥道を歩く際に滑り止めとして有効に機能すると共に、これが歩行中に前後又は左右等にずれることもなく、しかも装着用の弾性バンド手段を損傷する危険も極めて少ないので、滑落等を防止しながらより安全な歩行を確保することができる。更にはその取り外しも簡単であり、携帯及び保管にも便利である。
【００５１】
まず、この実施例の簡易アイゼンの登山靴Ｓへの装着は次のように行う。
装着に先立って、フロントプレート１とヒールプレート２とを結合するジョイント鎖３の長さを調節しておく。これは、必要以上に長い部分をカットすることにより行うことができる。また装着する登山靴Ｓの甲側を無用に強くない適切な締付力で保持できるように前後連結部９ｅ、９ｆの長さを調節しておく。これは該前後連結部９ｅ、９ｆと踵側締付部９ｇ、９ｈとの境界を移動させることで行う。この境界の移動は、結び部９ｉをどちらかに移動した部分に形成して中間係止球１１ｃ、１１ｄをどちらかに移動した部位に係止させることにより行う。
【００５２】
更に、登山靴Ｓの踵上部を踵上部抱持鎖６によって、十分な締付力をもって締め付け得る長さに踵側締付部９ｇ、９ｈを調節しておく。これは踵側締付部９ｇ、９ｈの端部側に於ける端部係止球１１ａ、１１ｂの取付け位置を調節することにより行う。これも端部側の結び部９ｉの形成位置を調整することによって行うことができる。なお、踵側締付部９ｇ、９ｈの端部係止球１１ａ、１１ｂより端部側に無用に延びる部分は必要に応じてカットする。
【００５３】
このように調節した後、図１に示すように、フロントプレート１及びヒールプレート２を、前者を前に後者を後に位置させながら、その横ズレ防止ピン５、５…の立ち上がった面を上向きにして配し、この上に、図６に示すように、登山靴Ｓを載せる。図中にはこれを履いている登山者の足は描かれていないが、これは作図の都合上であって、実際には登山靴Ｓは登山者が履いた状態でこの簡易アイゼンの装着を行う。
【００５４】
上記状態のフロントプレート１の上には、登山靴Ｓの爪先付近から土踏まずの手前付近までを載せ、ヒールプレート２には踵部付近を載せる。
図６に示すように、このとき、前記吊上補助片１０を持上げて、該吊上補助片１０から垂下する弾性バンド紐９の吊上垂下部９ａ、９ｂ、９ｃ、９ｄ及びこれらに被吊上環８ｃ、８ｄ、７ａ、７ｂを介して吊上げられている爪先部抱持鎖８の立ち上げ鎖部８ａ、８ｂ、爪先抱持鎖部８ｅ並びに側部抱持鎖７、７で囲まれる部分に該登山靴Ｓの前甲部が装入状態となるようにする。
【００５５】
次いで、図６に示すように、この状態で、踵上部抱持鎖６を登山靴Ｓの踵部の後側に配置させ、前方の吊上補助片１０から後方に延長している弾性バンド紐９の前後連結部９ｅ、９ｆを該登山靴Ｓの両側に位置させておく。該弾性バンド紐９の途中は、この状態で、前記踵上部抱持鎖６の途中にスライド移動自在に配した踵上部吊上補助片１３、１３の紐通過孔１３ａ、１３ａを貫通し、その後方の部位である踵側締付部９ｇ、９ｈがそれより後方に位置しているのは云うまでもない。
【００５６】
この後、前記弾性バンド紐９を該登山靴Ｓの後方かつ上方に引張って、その前後連結部９ｅ、９ｆと前記踵側締付部９ｇ、９ｈとの境界に位置する中間係止球１１ｃ、１１ｄを後方かつ上方に移動させ、これを通じて踵上部抱持鎖６の途中にスライド自在に配した踵部吊上補助片１３、１３を後方かつ上方に移動させ、その中央部付近、即ち、踵上部付近でこれら相互をほぼ当接状態にさせる。こうして登山靴Ｓの踵部は踵上部抱持鎖６の両端と中央部分との間の部分で抱持されることとなる。
【００５７】
なお前記中間係止球１１ｃ、１１ｄは、相互に概ね当接状態になってそれ以上動けなくなった踵上部吊上補助片１３、１３に係止して、それより後部の弾性バンド紐９である踵側締付部９ｇ、９ｈをそれ以上引いて張力を高めても動くことはなくなる。即ち、弾性バンド紐９に加えられる張力は前記中間係止球１１ｃ、１１ｄ及び踵上部吊上補助片１３、１３によって分断され、その前後側を異なった張力で締め付け得ることとなる。
【００５８】
また、前記のように、弾性バンド紐９を後方かつ上方に引っ張ると、前記踵上部抱持鎖６の両端近傍にその両端を結合した係止バー部材１４も、同時に引き上げられ、図７に示すように、登山靴Ｓの踵上部で、靴底部Ｓ１周縁の上部に係止することとなる。
【００５９】
続いて、弾性バンド紐９を踵上部で交差させる形で、両踵部吊上補助片１３、１３の紐通過孔１３ａを貫通した踵側締付部９ｇ、９ｈを足首部前方に引張り、概ね当接状態の該踵部吊上補助片１３、１３を登山靴Ｓの踵上部側にしっかりと締付固定するとともに、その一方の踵側締付部９ｇの前端に配してある紐端留め片１２の切欠付係止孔１２ｂに他方の踵側締付部９ｈの端部係止球１１ａの手前を挿入係止する。
【００６０】
この後、更にこの時点で登山靴Ｓの両側中間高さ位置付近に位置している弾性バンド紐９の前後連結部９ｅ、９ｆをそれぞれ前記紐端留め片１２の下部側に引き上げ、これらをその切欠付係止孔１２ｃに貫通係止する。これで登山靴Ｓへのこの実施例の簡易アイゼンの装着は完了である。
【００６１】
なお、登山靴Ｓからこの実施例の簡易アイゼンを取外す場合は、先ず、弾性バンド紐９の前後連結部９ｅ、９ｆを紐端留め片１２の切欠付係止孔１２ｃから取外す手順が操作し易い。
【００６２】
以上の説明は、図６に示すように、左側の登山靴Ｓへの装着に関してのみ行ったが、この簡易アイゼンは、左右の区別なく使用することができるものであり、右側の登山靴Ｓへの装着操作も左側のそれと同様に行えば良く、同様に簡単に装着できる。
【００６３】
このようにこの実施例の簡易アイゼンによれば、図６に示すように、フロントプレート１及びヒールプレート２を、登山靴Ｓの足首後部側では踵上部抱持鎖６と係止バー部材１４とで支持し、爪先側では爪先部抱持鎖８で巻いて支持し、側部では側部抱持鎖７、７で支持し、かつこれらの爪先部抱持鎖８及び側部抱持鎖７、７は登山靴Ｓの前甲部に配置された吊上補助片１０の吊上補助孔１０ａ、１０ｂ、１０ｃ、１０ｄ、１０ｅ、１０ｆ、１０ｇ、１０ｈから垂下された弾性バンド紐９の吊上垂下部９ａ、９ｂ、９ｃ、９ｄで吊上げ、また該吊上補助片１０は踵上部抱持鎖６と弾性バンド紐９の前後連結部９ｅ、９ｆで互いに支持し合い、更に踵上部抱持鎖６は弾性バンド紐９の踵側締付部９ｇ、９ｈで、前甲部を必要以上に締付けることなく、しっかりと吊上げ締め付けることにより、登山靴Ｓに装着するものであり、登山靴Ｓの種類を問わず安全確実にしかも簡単かつスピーディに装着できるものである。
【００６４】
また、この実施例の簡易アイゼンは、前記ヒールプレート２及び前記フロントプレート１の下部にスパイク４、４…を突出させてあり、これによって氷雪上や泥道に於ける滑り止めの効果が十分発揮できるのは云うまでもなく、該ヒールプレート２及び該フロントプレート１の上面に横ズレ防止ピン５、５…が立ち上がっているため、踵上部抱持鎖６、係止バー部材１４、側部抱持鎖７、７及び爪先部抱持鎖８の作用と相俟って、歩行中に該ヒールプレート２及び該フロントプレート１が前後又は左右にズレるような虞がない。それ故一層歩行の安全性が確保できるものである。
【００６５】
更に前記弾性バンド紐９は、装着時に登山靴の左右両側を通過する前後連結部９ｅ、９ｆが登山靴Ｓの甲側足首部に配置されている前記紐端留め片１２の下部の切欠付係止孔１２ｃに引き寄せて係止されるため、雪の消えたガレ場の岩や、灌木帯等での木の枝、或いは木の根等に接触する虞が低下し、そのため該弾性バンド紐９の損傷の虞は非常に低いものとなる。加えて該弾性バンド紐９は保護被覆を備えたものであるため、たとえ、それらに接触するようなことがあったとしても容易に破断等の損傷を生じる虞がなく、より安全に使用できるものである。
【００６６】
【発明の効果】
本発明の１の簡易アイゼンによれば、登山靴の種類を問わずに装着可能であり、装着に際し各部を所望の強さで締付けることができ、また左右のバランスも取り易く、かつ着脱も簡単である。更に歩行中に登山靴にしっかりと固定され、安全に歩行できると共に、装着のためのバンド手段の装着位置が、歩行に際して、登山道の岩や木の根等の種々のものと接触しにくい位置関係に配置されるためその損傷の危険性も低く、かつ携帯にも便利である。
【００６７】
本発明の２の簡易アイゼンによれば、二つの被吊上部材が、踵上部抱持鎖上をこれを貫通させた貫通孔によってスライド自在に移動可能となっているため、この簡易アイゼンを登山靴に装着した際に、該被吊上部材が、該登山靴の踵上部に移動して相互に当接し合うこととなり、無理なく踵上部抱持鎖の踵上部への引き上げと、その位置決めが可能となるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a simple crampon suitable for being attached to a mountain climbing shoe when walking on a snowy mountain, a snowy valley, or a slippery mud.
[0002]
[Prior art]
Needless to say, Aizen is attached to climbing shoes for safe walking on snow and snow in snowy mountains, but it is not only for severe winter mountain climbing but also snowy low mountains, summer snowy valleys, or slippery. It is also effective for preventing slipping on muddy roads. There are a lot of simple crampons that are used for light mountain climbing, but they are both difficult to put on and take off, are inconvenient to carry, or are worn depending on the type of shoes. It is difficult to say that a satisfactory product has been provided, such as being unsatisfactory or being easily shifted back and forth or left and right while walking.
[0003]
Therefore, the present inventor has proposed a new simple crampon (Patent Document 1) to solve these problems.
This is "in the Aizen equipped with a front plate and a heel plate, which are coupled with each other by flexible joint members, each having a plurality of spikes, and band means for attaching them to a mountain climbing shoe.
The spike is a plurality of protrusions projecting downward from both the front plate and the heel plate, each of which includes a protrusion that integrally includes a lateral misalignment prevention pin that rises above the front plate and the heel plate. And
The band means;
A rear holding band supported by a rear rising chain raised from both sides of the heel plate, the rear holding band supporting the rear portion of the shoe in a holding state;
Of the two front riser chains raised from both sides of the front plate, it is connected to the two front riser chains on one side and detachably connected to the two front riser chains on the other side. A front upper holding band of a shoe that extends from the side connected to the front rising chain to the rear and extends to the extended binding piece extended from the rear holding band on the same side. With an upper hug band,
Of each two front rising chains on both sides, a front holding chain for holding the front part of the shoe disposed between the upper part of the front rising chain on the front side,
A detachable extension piece extending symmetrically with the extension coupling piece from the front upper holding band, and detachably extending from the rear holding band to a detachable extension piece symmetrically extended with the extension coupling piece. And
And the rear holding band, the front upper holding band, the rear holding band, the extended coupling pieces of the front upper holding band, and the attachment and detachment extension pieces of the front upper holding band constituting the band means " is there.
[0004]
Such simple crampons are easier to put on and take off than the earlier crampons mentioned earlier, are not inconvenient to carry and can be worn regardless of the type of shoes, and while walking It can be said that it is excellent without any problem of shifting back and forth or left and right.
[0005]
However, by further examination after that, when walking without removing the gale field where the snow partially disappeared, or the shrub belt or other areas where the branches of trees were complicated, the elastic material used as a band means, In view of the configuration, it has been clarified that there is no denying the possibility of damaging it due to the fact that the rubber plate must be made of a member that has been punched out.
[0006]
In addition, this simple crampon is much easier to wear than previous crampons, but when it was worn, a pair of bands for coupling were used with the heel plate and front plate stepped on with climbing shoes. Since the members should be operated from the outside to the inside so that the hooks at their respective tips are hooked on the ring of the inside member, they tend to be pulled outward or inward by the elasticity of each band member, and are attached with a good balance between inside and outside. It turned out to be a little cumbersome and there was no room for improvement in terms of usability.
[0007]

[Problems to be solved by the invention]
The present invention solves the above-mentioned problems of the prior art, can be easily and well-balanced regardless of the type of shoe, and the upper side of the heel side of the shoe can be firmly and firmly locked, The upper part of the shoe should not be tightened more than necessary and, in addition, to ensure safe walking, it is securely fixed to the shoe during walking. The problem to be solved is to provide a simple cramp that is easy to carry and has a low risk of damage.
[0009]
[Means for Solving the Problems]
A first aspect of the present invention is an Aizen comprising a front plate and a heel plate which are connected to each other by a flexible joint member and each provided with a plurality of spikes, and band means for attaching these to a mountain climbing shoe. And
The spike is a plurality of protrusions projecting downward from both the front plate and the heel plate, each of which includes a protrusion that integrally includes a lateral misalignment prevention pin that rises above the front plate and the heel plate. And
The band means;
Both ends are raised from the left and right sides of the heel plate, and the heel upper part holding chain that holds the heel part of the mountaineering shoes to be attached in the middle of the heel plate. The upper heel holding chain,
Both ends are raised from the left and right front side parts of the front plate, and the toe part of the mountaineering shoe to be worn is held at the middle part, and each boundary between the middle part and the raised parts on both sides thereof is configured in the suspended upper part. A toe part holding chain,
A pair of left and right side holding chains each rising from the left and right rear sides of the front plate, each upper end being configured as a suspended upper part,
A pair of lifting auxiliary holes used on the front insteps of the mountaineering shoes to be opened by opening each pair of lifting auxiliary holes on the left and right front sides and rear sides,
A locking hole and a locking hole with a notch are arranged in parallel on the upper part, and an enlarged portion of one end of the elastic band cord described later is connected to the former in a state of retaining, and the latter is connected to the other end of the elastic band cord described later. It is a string end clip that allows the enlarged part to be detachably connected, and when a notch locking hole is placed in the lower part and this simple crampon is attached to a mountaineering shoe, it is located on the instep ankle part. A string end retaining piece configured to be detachably engageable with each of the elastic band strings passing through both sides of the mountain climbing shoes in the notched locking holes;
The elastic band strap provided with a protective coating, wherein the middle portion in the longitudinal direction is positioned on the center of the front portion of the lifting assisting piece, and the middle portion of the extension to both sides of the lifting assisting piece A pair of lifting auxiliary holes on the corresponding front side are inserted into and suspended from the front side of each of the auxiliary auxiliary holes, and are inserted into the rear side of each of the toe portion holding chains after penetrating and locking. Then, it is pulled out onto the lifting auxiliary piece, and further each is inserted into and suspended from the front side of the pair of lifting auxiliary holes on the corresponding rear side of the lifting auxiliary piece, and the corresponding side of each side. After penetrating and locking to the suspended upper part at the upper end of the holding chain, it is inserted into each rear side, pulled out on the lifting auxiliary piece, and each is extended rearward, and further the intermediate enlarged portion Two suspended members whose rear is arranged in the middle of the heel plate holding chain of the heel plate It penetrates through the corresponding side, and the front end of the extension of one of the extension portions is passed through and locked into the locking hole of the end piece of the string end, and the one extension portion and the other extension portion are connected to this end portion. When a simple crampon is attached to a mountaineering shoe, it is turned to the instep side ankle portion of the mountaineering shoe and the end portion of the other extension portion is locked to the end of one extension portion immediately before the end portion of one extension portion. In the state where it is detachably coupled to the notched locking holes, the elastic band straps passing through both sides of the mountain climbing shoes are formed in the lower portions of the strap end fastening pieces in the middle of the elastic band straps. It is a simple cramp made up of an elastic band string that can be locked through.
[0010]
Therefore, according to the simple crampons of the present invention, it is easy to carry and can be easily attached to and detached from mountain climbing shoes when necessary. Moreover, since the elastic band cord provided with the protective coating was employ | adopted as the component which requires the elasticity of a band means for the attachment, it can also hold | maintain reliably. This is because the elastic band strap secures protection by a protective coating, and furthermore, it is a strap and the area that contacts various external parts is small, and it is also suitable for climbing shoes. It is constructed so that it is placed at the center of the mountaineering shoe like the center of the upper part of its ankle or instep, so that the elastic band strap of the rock and shrub belt where the snow and ice disappeared during walking This is because the possibility of being damaged by contact with the root of the tree is extremely low.
[0011]
Furthermore, since the elastic band strap is a single flexible member that is lightweight and not bulky, it is convenient to carry as a spare part, and even if damaged, it can be easily replaced, so that even higher substantial safety improvements can be achieved. I can plan.
[0012]
Further, according to the simple crampon of the present invention, the heel plate is positioned under the heel portion of the mountaineering shoe, the front plate is located under the toe portion, and the lifting assisting piece is located at the front portion of the mountaineering shoe instep. It is surrounded by the toe part holding chain etc. of the object to be lifted that is suspended by the corresponding part of the suspension band and the elastic band strap suspended from each of the pair of lifting assist holes and the suspended upper part. Insert the toe part of the mountaineering shoe from the back into the space, pull the elastic band strap from left to right evenly from the front to the back, and the rear of each enlarged part provided in the middle to the upper part of the corresponding suspended member on both sides While penetrating and pulling them crossing each other, the suspended members on both sides are brought into contact with each other, and in this state, elastic band straps on both sides are further turned forward of the mountain climbing shoes, and thereby the upper-end holding chain is climbing shoes Lift up the upper part of the heel and pull out the enlarged end of one elastic band The cord end retaining piece is engaged with the stop state, locking the distal enlarged portion of the elastic band cord which is not sealed the other engages the notch with locking holes in the upper portion thereof. In this way, both sides of the elastic band strap are pulled evenly on the left and right sides and tightened, so that the attachment can be performed with good balance with respect to the climbing shoes.
[0013]
Then, the middle part of the elastic band that passes near the lower side of the string end fastening piece on both sides of the mountain climbing shoe is pulled to the center side, and is through-engaged with the notched locking holes arranged in the lower part of the string end fastening piece. . This completes the installation to the mountaineering shoes, and the installation operation can be performed very easily.
[0014]
In this state, since the elastic band straps are elastically balanced with respect to each other in front of the ankles, the engaging operation can be easily performed. In addition, the elastic band is only placed around the upper center of the instep of the mountain climbing shoe and around the ankle, so this can be used when walking on rocky places where snow has disappeared, the roots of trees, and the paths where shrubs protrude. The possibility of being damaged by being caught on them becomes very low.
[0015]
In addition, since the elastic band strap has a rear portion of the enlarged portion for retaining the same passing through the upper portion of the suspended member disposed in the middle of the hook upper portion holding chain, No matter how strongly the extension part is pulled, the part in front of the enlarged part does not move backward through the suspended member. Further, when the elastic band strap is pulled strongly as described above, the two lifted members come into contact with each other and are stopped in the vicinity of the middle portion of the collar upper holding chain.
[0016]
For this reason, the front portion from the enlarged portion is not tightened more than necessary, and the enlarged portion tries to make the holding state of the upper portion of the climbing shoe by the upper portion holding chain a strong tightened state. Even if the length of the back is shortened and both ends of the ankle are locked to the strap end clip, the middle part of the elastic band strap located on the back side of the mountain climbing shoe is There is no risk of being tightened strongly.
[0017]
Further, in the simple crampons of the present invention, spikes protrude from the lower portions of the heel plate and the front plate, so that it is possible to sufficiently exhibit the anti-slip effect on ice and snow and in mud roads. However, since the lateral displacement prevention pins are raised on the upper surfaces of the heel plate and the front plate, there is no possibility that they may be shifted back and forth or left and right during walking. Therefore, further safety of walking can be secured.
[0018]
A second aspect of the present invention is the simplified crampon according to the first aspect of the present invention, wherein two suspended members, which are slidably arranged in the middle of the collar upper-holding chain, are respectively provided at the lower part thereof, and It is configured to have a through hole that allows the penetrating chain to pass therethrough and a locking hole that is provided in the upper part and penetrates the rear of the intermediate enlarged portion in the middle of each of the elastic band straps.
[0019]
Therefore, according to the simple cramp of 2 of the present invention, the two suspended members can be slidably moved through the through-holes penetrating the upper hanger chain. When mounted on a mountain climbing shoe, the suspended member moves to the upper part of the heel of the mountain climbing shoe and comes into contact with each other. Can be performed.
[0020]
According to a third aspect of the present invention, in the simplified crampon according to the first or second aspect of the present invention, the enlarged portion is formed at a corresponding portion of the elastic band cord, and the elastic band cord is inserted into a through-hole of a locking ball. The knot portion is inserted into the large diameter portion of the through hole, and the portion extending from the knot portion is pulled out from the small diameter portion.
[0021]
Therefore, according to the simple cramp of 3 of the present invention, the enlarged portion can be configured to be able to be reliably locked to the suspended upper portion or the locking hole or the notched locking hole of the string end fastening piece, and the appearance thereof is also provided. It has the advantage of being excellent.
[0022]
4 of the present invention is the simplified crampon of 1, 2 or 3 of the present invention, in the vicinity of both ends of the heel upper-holding chain, locked to the upper portion of the shoe sole rim at the upper portion of the heel when attached to a mountaineering shoe. In this way, both ends of the locking bar member are attached.
[0023]
The locking bar member needs to have a certain degree of rigidity because the locking bar member should be securely locked to the periphery of the shoe sole that protrudes slightly around the heel of the mountain climbing shoe. From such a viewpoint, a metal rod having an appropriate thickness can be employed. For example, a rod such as brass or stainless steel can be used. The locking bar member preferably has an arc shape that matches the shape of the upper part of the periphery of the shoe sole portion of the mountaineering shoe to be worn, but it is not so long and may be linear. Further, when a metal member is adopted as the material, it is convenient in many cases because it becomes an arc shape corresponding to the rear shape of the shoe during wearing.
[0024]
Further, as described above, the locking bar member is attached to both ends in the vicinity of both ends of the collar upper holding chain, and the mounting position in the vicinity of both ends is to climb this as described above. When the shoe is attached to a shoe, the locking bar member can be satisfactorily locked to the upper portion of the shoe rim. In addition, the attachment of the hook upper holding chain and the end of the locking bar member is, for example, processing both ends of the locking bar member into a hook shape, and directly connecting them to the hook upper holding chain. It can be done by locking to the corresponding part, or by connecting S-rings, chain members and other members with the required strength to both ends of the locking bar member and connecting them through these It is.
[0025]
Therefore, according to 4 of the present invention, since the locking bar member is locked to the upper portion of the shoe sole at the heel of the mountain climbing shoe when mounted on the mountain climbing shoe, Further, the heel plate is more securely fixed by the both side portions of the upper collar holding chain. Therefore, the heel plate does not cause lateral displacement, vertical displacement or misalignment during walking, and a safer walking can be ensured.
[0026]
