【０００１】
【発明の属する技術分野】
この発明は、紐状ないしは帯状物の端部を覆うように、この端部に取り付けられて用いられる端部カバーの改良に関する。
【０００２】
【従来の技術】
ヒンジ部を介して連接され、このヒンジ部を変形させながら重ね合わされる第一部分と第二部分を有しており、この重ね合わせ状態において、間に入れ込まれた紐状物の端部に第一部分と第二部分の重ね合わせ側にそれぞれ設けられたスパイクを突き刺し、あるいは、突き立てるようにして、この紐状物の端部を覆うように取り付けられる端部カバーとして、特許文献１に示されるものがある。
【０００３】
【特許文献１】
意匠登録第１０１９０６５号公報
【０００４】
【発明が解決しようとする課題】
しかるに、特許文献１に示される端部カバーは、紐状物の端部への取り付け状態の確保を、この端部への前記スパイクの突き刺し、あるいは、突き立てによらしめるに留まるものであった。
【０００５】
そこで、この発明は、紐状ないしは帯状物の端部に対し、容易かつ安定的に取り付けることができると共に、この端部のカバー状態を常時安定的に維持可能な端部カバーを提供することを主たる目的とする。
【０００６】
【課題を解決するための手段】
前記目的を達成するために、請求項１記載の発明にあっては、紐状ないしは帯状物の端部カバーを、以下の（１）〜（３）の構成を備えたものとした。
（１）頭部と、紐状ないしは帯状物を挟持可能とする少なくとも二以上の挟持用脚部とを備えた雄部材と、
（２）筒一端を紐状ないしは帯状物の引き出し開口とし、かつ、筒他端を雄部材の挟持用脚部の入れ込み開口とした筒状をなす雌部材とを備えていると共に、
（３）雌部材には、紐状ないしは帯状物を間に入れ込ませた状態で入れ込み開口から雌部材内に入れ込まれる雄部材の挟持用脚部を、この入れ込みに伴って紐状ないしは帯状物を挟み付ける向きに撓み込ませる締め込み用内壁部が備えられている。
【０００７】
かかる構成によれば、雌部材の引き出し開口から雌部材内に入れ込まれ、かつ、入れ込み開口から引き出された紐状ないしは帯状物の端部を、雄部材の二以上の挟持用脚部の間に入れ込ませた後、
この雄部材の二以上の挟持用脚部を雌部材の入れ込み開口からこの雌部材内に入れ込ませることによって、この二以上の挟持用脚部を前記締め込み用内壁部によって撓み込ませることができ、このように撓み込まされる二以上の挟持用脚部によってこの二以上の挟持用脚部間に入れ込まれた紐状ないしは帯状物の端部をこの二以上の挟持用脚部間から抜け出さないように挟み付けることができる。
【０００８】
そして、これにより、紐状ないしは帯状物の端部にワンタッチで端部カバーを取り付けて、このように雄部材が入れ込まれた雌部材によって紐状ないしは帯状物の端部を覆うようにすることができる。
【０００９】
紐状ないしは帯状物にテンションが作用されると、この紐状ないしは帯状物の端部を雌部材内において挟持用脚部によって挟み付けている雄部材にも引き出し開口側に向けた力が作用されることになるが、このような力が作用されると前記締め込み用内壁部によって挟持用脚部はより前記端部を挟み付ける向きに撓み込まされることになることから、挟み付けられているこの端部は前記テンション作用時にも挟持用脚部間から、つまり、雌部材内から抜け出し難く、この端部のカバー状態を安定的に確保させることができる。
【００１０】
また、請求項２記載の発明にあっては、請求項１記載の紐状ないしは帯状物の端部カバーにおける雌部材の締め込み用内壁部が、引き出し開口に近付くに連れてこの雌部材の内部空間を小さくさせるように傾斜した構成としてあることを特徴としている。
【００１１】
かかる構成によれば、雌部材内に入れ込まれる雄部材の挟持用脚部を、雌部材内への入れ込み量が増えるに従って次第に大きく撓み込まさせることができ、雌部材内への雄部材の挟持用脚部の入れ込みをスムースに行わせることができる。
【００１２】
また、紐状ないしは帯状物にテンションが作用されると、この紐状ないしは帯状物の端部を雌部材内において挟持用脚部によって挟み付けている雄部材にも引き出し開口側に向けた力が作用されることになるが、このような力が作用されるとこのように傾斜された前記締め込み用内壁部によって挟持用脚部はより前記端部を挟み付ける向きに強固に撓み込まされることになることから、挟み付けられているこの端部は前記テンション作用時にも挟持用脚部間から、つまり、雌部材内から抜け出し難く、この端部のカバー状態を安定的に確保させることができる。
【００１３】
また、請求項３記載の発明にあっては、請求項１又は請求項２記載の紐状ないしは帯状物の端部カバーにおける雄部材の挟持用脚部に、挟持される紐状ないしは帯状物に対するスパイクとして機能する突起が備えられていることを特徴としている。
【００１４】
かかる構成によれば、二以上の挟持用脚部間に紐状ないしは帯状物の端部を入れ込ませた状態からこの挟持用脚部を雌部材内に入れ込ませることに伴って、前記のように撓み込まされる挟持用脚部によりかかる端部に前記突起を突き刺させ、あるいは、突き立てさせることができ、この突起によってかかる端部を一層確実に保持させることができる。
【００１５】
また、請求項４記載の発明にあっては、請求項１から請求項３のいずれか一項に記載の紐状ないしは帯状物の端部カバーにおける雄部材の挟持用脚部を、紐状ないしは帯状物にテンションが作用された際に、このテンションの作用に伴う雌部材の引き出し開口側に向けた挟持用脚部の移動を弾性変形しながら許容させる連接体を介して頭部に連接させていることを特徴としている。
【００１６】
かかる構成によれば、こうしたテンションが作用された際に、雌部材内への入れ込みにより撓み込まされた挟持用脚部によって紐状ないしは帯状物を雌部材内で把持している雄部材の挟持用脚部を、このテンションによって雌部材内から抜け出そうとする紐状ないしは帯状物と一緒に同じ向きに移動させることができ、こうしたテンションによっても紐状ないしは帯状物の端部に対する挟持用脚部の把持位置にズレを生じさせることがなく、この端部の把持状態を安定的に維持させることができる。また、こうしたテンションの作用がなくなった場合には、前記連接体の弾性復帰により、挟持用脚部を再び所期の位置に復帰させることができる。
【００１７】
また、請求項５記載の発明にあっては、請求項１から請求項４のいずれか一項に記載の紐状ないしは帯状物の端部カバーにおける雄部材の頭部と雌部材の入れ込み開口側とのいずれか一方に、これらの他方に形成された被掛合部に対し、雌部材内に雄部材の挟持用脚部を入れ込み切った位置で掛合される掛合部が形成してあることを特徴としている。
【００１８】
かかる構成によれば、雄部材の二以上の挟持用脚部間に紐状ないしは帯状物の端部を入れ込ませた状態で、雌部材内にこの挟持用脚部を入れ込み切っることにより作出されたこの端部をカバーさせた状態を、安定的に維持させることができる。
【００１９】
【発明の実施の形態】
以下、図１ないし図２５に基づいて、この発明の典型的な実施の形態について説明する。
【００２０】
なお、ここで図１は、実施の形態にかかる端部カバーを紐状ないしは帯状物Ｗ（図示の例では、紐状体）の端部Ｗａに取り付ける直前の状態を、また、図２は、かかる取り付けをなした状態を、また、図３は、図２の状態から紐状ないしは帯状物Ｗにテンションが作用された状態を、それぞれ示している。
【００２１】
また、図４ないし図９は、かかる端部カバーを、図１０ないし図１５は、かかる端部カバーを構成する雌部材２を、さらに、図１６ないし図２５は、かかる端部カバーを構成する雄部材１を、それぞれ示している。
【００２２】
この実施の形態にかかる端部カバーは、紐状ないしは帯状物Ｗの端部Ｗａを覆うように、この端部Ｗａに取り付けられて用いられるものである。かかる端部カバーは、紐状ないしは帯状物Ｗの端部Ｗａの外観性を向上させる機能を有する。また、かかる端部カバーは、紐状ないしは帯状物Ｗの端部Ｗａの解れなどを防止する機能を有する。また、かかる端部カバーは、引き紐などとして用いられる紐状ないしは帯状物Ｗにおいては、引き操作をなすための把持部分となる機能を有するものである。
【００２３】
紐状物としては、典型的には、丸紐、平紐、ゴム紐、合成樹脂製のコードなどが予定される。また、帯状物としては、扁平で、平紐よりも幅の広いバンドなどが予定される。
【００２４】
かかる端部カバーは、雄部材１と雌部材２とを備えて構成される。
【００２５】
雄部材１は、頭部１０と、少なくとも二以上の挟持用脚部１１、１１…とを備えている。二以上の挟持用脚部１１、１１…は、紐状ないしは帯状物Ｗを挟持可能とするものである。すなわち、二以上の挟持用脚部１１、１１…は、これらの間に入れ込ませた紐状ないしは帯状物Ｗの端部Ｗａを他の挟持用脚部１１と協働して挟み付けることができるように構成されている。
【００２６】
一方、雌部材２は、両筒端を開放させた筒状をなすように構成されている。そして、かかる雌部材２は、筒一端を紐状ないしは帯状物Ｗの引き出し開口２０とし、かつ、筒他端を雄部材１の挟持用脚部１１の入れ込み開口２１とするように構成されている。
【００２７】
そして、この雌部材２には、紐状ないしは帯状物Ｗを間に入れ込ませた状態で入れ込み開口２１から雌部材２内に入れ込まれる雄部材１の挟持用脚部１１を、この入れ込みに伴ってこの紐状ないしは帯状物Ｗを挟み付ける向きに撓み込ませる締め込み用内壁部２２が備えられている。
【００２８】
これにより、かかる端部カバーによれば、雌部材２の引き出し開口２０から雌部材２内に入れ込まれ、かつ、入れ込み開口２１から引き出された紐状ないしは帯状物Ｗの端部Ｗａを、雄部材１の二以上の挟持用脚部１１、１１…の間に入れ込ませた後、（図１）
この雄部材１の二以上の挟持用脚部１１、１１…を雌部材２の入れ込み開口２１からこの雌部材２内に入れ込ませることによって、この二以上の挟持用脚部１１、１１…を前記締め込み用内壁部２２によって撓み込ませることができ、このように撓み込まされる二以上の挟持用脚部１１、１１…によってこの二以上の挟持用脚部１１、１１…間に入れ込まれた紐状ないしは帯状物Ｗの端部Ｗａをこの二以上の挟持用脚部１１、１１…間から抜け出さないように挟み付けることができる。（図２）
【００２９】
そして、これにより、紐状ないしは帯状物Ｗの端部Ｗａにワンタッチで端部カバーを取り付けて、このように雄部材１が入れ込まれた雌部材２によって紐状ないしは帯状物Ｗの端部Ｗａを覆うようにすることができる。
【００３０】
紐状ないしは帯状物Ｗにテンションが作用されると、この紐状ないしは帯状物Ｗの端部Ｗａを雌部材２内において挟持用脚部１１によって挟み付けている雄部材１にも引き出し開口２０側に向けた力が作用されることになるが、このような力が作用されると前記締め込み用内壁部２２によって挟持用脚部１１はより前記端部Ｗａを挟み付ける向きに撓み込まされることになることから、挟み付けられているこの端部Ｗａは前記テンション作用時にも挟持用脚部１１間から、つまり、雌部材２内から抜け出し難く、この端部Ｗａのカバー状態を安定的に確保させることができる。
【００３１】
図示の例にあっては、雌部材２は、扁平の筒状をなすように構成されている。すなわち、図示の例にあっては、雌部材２は、その筒軸に対し直交する向きの断面において、ほぼいずれの位置においても、外郭形状および内郭形状を共にほぼ楕円状とするように構成されており、短寸側の内外壁と長寸側の内外壁とを持つように構成されている。
【００３２】
一方、雄部材１は、一対の挟持用脚部１１、１１を有するものとして構成されている。そして、図示の例にあっては、この雄部材１の頭部１０における一対の挟持用脚部１１、１１との連接側の面が雌部材２の入れ込み開口２１を巡る縁部に突き当てられる位置まで、雌部材２内に雄部材１の挟持用脚部１１を入れ込めるようになっており、この位置が雌部材２内に雄部材１を入れ込み切った位置となるようにしてある。また、雄部材１は、この一対の挟持用脚部１１、１１の一方の先端部Ｗａの外側を雌部材２の一方の短寸側の内壁部２３に接しさせ、かつ、この一対の挟持用脚部１１、１１の他方の先端部Ｗａの外側を雌部材２の他方の短寸側の内壁部２３に接しさせながら、雌部材２内に挟持用脚部１１を入れ込ませるように構成されている。図示の例にあっては、雌部材２の締め込み用内壁部２２は、この雌部材２の短寸側の内壁部２３によって構成されている。
【００３３】
そして、この実施の形態にあっては、雌部材２の締め込み用内壁部２２が、引き出し開口２０に近付くに連れてこの雌部材２の内部空間を小さくさせるように傾斜した構成としてある。
【００３４】
これにより、雌部材２内に入れ込まれる雄部材１の挟持用脚部１１を、雌部材２内への入れ込み量が増えるに従って次第に大きく撓み込まさせることができ、雌部材２内への雄部材１の挟持用脚部１１の入れ込みをスムースに行わせることができる。
【００３５】
また、紐状ないしは帯状物Ｗにテンションが作用されると、この紐状ないしは帯状物Ｗの端部Ｗａを雌部材２内において挟持用脚部１１によって挟み付けている雄部材１にも引き出し開口２０側に向けた力が作用されることになるが、このような力が作用されるとこのように傾斜された前記締め込み用内壁部２２によって挟持用脚部１１はより前記端部Ｗａを挟み付ける向きに強固に撓み込まされることになることから、挟み付けられているこの端部Ｗａは前記テンション作用時にも挟持用脚部１１間から、つまり、雌部材２内から抜け出し難く、この端部Ｗａのカバー状態を安定的に確保させることができる。
【００３６】
図示の例では、雌部材２の入れ込み開口２１側においては、この雌部材２の一対の短寸側の内壁部２３間の間隔は、雄部材１の一対の挟持用脚部１１、１１の先端の外面部間（より具体的には、図示の例では、後述する位置決め用突起１７の突き出し端間）の寸法よりやや大きいが、この一対の短寸側の内壁部２３間の間隔はここから引き出し開口２０側に向けて、前記締め込み用内壁部２２によって、次第に狭まるように構成されている。
【００３７】
また、この実施の形態にあっては、雄部材１の挟持用脚部１１に、挟持される紐状ないしは帯状物Ｗに対するスパイクとして機能する突起１２が備えられている。
【００３８】
これにより、二以上の挟持用脚部１１、１１…、図示の例では一対の挟持用脚部１１、１１間に紐状ないしは帯状物Ｗの端部Ｗａを入れ込ませた状態からこの挟持用脚部１１を雌部材２内に入れ込ませることに伴って、前記のように撓み込まされる挟持用脚部１１によりかかる端部Ｗａに前記突起１２を突き刺させ、あるいは、突き立てさせることができ、この突起１２によってかかる端部Ｗａを一層確実に保持させることができる。
【００３９】
図示の例にあっては、雄部材１の頭部１０は、挟持用脚部１１の突き出し側の面と反対の側をドーム状をなすように構成されており、この挟持用脚部１１を雌部材２内に入れ込み切った位置において、この頭部１０によって雌部材２の入れ込み開口２１を塞ぐように構成されている。
【００４０】
また、図示の例にあっては、一対の挟持用脚部１１、１１は、この一対の挟持用脚部１１、１１の先端と反対の側の端部Ｗａ間に亙る基部片１３によってこの反対の側の端部Ｗａにおいて互いに連接されている。すなわち、かかる一対の挟持用脚部１１、１１とこの基部片１３とは全体としてコ字状をなすように一体化されている。そして、かかる一対の挟持用脚部１１、１１はそれぞれ、この基部片１３との連接側をおおむね中心として、その先端側を他方の挟持用脚部１１に近づける向きに、弾性変形するように構成されている。
【００４１】
また、かかる一対の挟持用脚部１１、１１はそれぞれ、他方の挟持用脚部１１に向き合った側に前記突起１２を備えている。
【００４２】
図示の例にあっては、かかる一対の挟持用脚部１１、１１の一方には、この一方の挟持用脚部１１における他方の挟持用脚部１１に向き合った側において、その先端側から基部片１３との連接側に向けて延びる溝状部１４が形成されている。そして、かかる一対の挟持用脚部１１、１１の一方においては、この溝状部１４を挟んだ両側にそれぞれ、前記突起１２が形成されている。かかる突起１２は、前記溝状部１４を挟んだ両側にそれぞれ設けられて一組をなすと共に、図示の例では、この一組の突起１２、１２がこの一対の挟持用脚部１１、１１の一方の長さ方向において間隔を開けて二カ所に備えられている。
【００４３】
一方、かかる一対の挟持用脚部１１、１１の他方には、この他方の挟持用脚部１１における一方の挟持用脚部１１に向き合った側において、前記突起１２が一つ設けられている。この他方の挟持用脚部１１に設けられている突起１２は、かかる他方の挟持用脚部１１の幅方向ほぼ中程の位置から一方の挟持用脚部１１の側に向けて突き出されている。また、図示の例にあっては、かかる他方の挟持用脚部１１の突起１２は、この挟持用脚部１１の長さ方向において、前記一方の挟持用脚部１１において二カ所に設けられた一組の突起１２、１２の間に、その突き出し端を位置させるように設けられている。
【００４４】
また、図示の例にあっては、一対の挟持用脚部１１、１１に設けられた突起１２はそれぞれ、その突き出し端を尖らせた外郭形状を円錐状をなすように構成されていると共に、この突起１２の基部から突き出し端に向かうに連れて、次第に挟持用脚部１１の先端から離れる向きに傾斜するように突き出されている。
【００４５】
これにより、図示の例にあっては、一対の挟持用脚部１１、１１間に紐状ないしは帯状物Ｗの端部Ｗａを入れ込ませた後、この一対の挟持用脚部１１、１１を雌部材２内に入れ込ませることにより撓み込まされる挟持用脚部１１によって、前記各突起１２をこの紐状ないしは帯状物Ｗにしっかりと食い込ませることができる。また、かかる各突起１２は、前記のように傾斜していることから、この紐状ないしは帯状物Ｗにテンションが作用された際には、より深くこの紐状ないしは帯状物Ｗに突起１２が食い込むみ、こうしたテンションの作用によって紐状ないしは帯状物Ｗの挟み付け状態が一層解かれ難くなるようになっている。また、前記一方の挟持用脚部１１の突起１２と他方の挟持用脚部１１の突起１２とは、挟持用脚部１１の長さ方向において異なる位置で紐状ないしは帯状物Ｗの端部Ｗａに突き刺さり、あるいは、突き立ち、かつ、挟持用脚部１１の幅方向において、一方の挟持用脚部１１の一組の突起１２間において他方の挟持用脚部１１の突起１２が紐状ないしは帯状物Ｗの端部Ｗａに突き刺さり、あるいは、突き立つようになっていることから、一対の挟持用脚部１１、１１によって紐状ないしは帯状物Ｗの端部Ｗａを強固に挟み付けることができるようになっている。さらに、一方の挟持用脚部１１には、前記溝状部１４が形成されていることから、前記突起１２の突き刺さり、ないし、突き立てによって変形させられた紐状ないしは帯状物Ｗの端部Ｗａの一部を、この溝状部１４によって逃させることができ、これにより、端部カバー全体をコンパクトに構成させることができるようになっている。図示の例では、一方の挟持用脚部１１の突起１２と、他方の挟持用脚部１１の突起１２とは、雌部材２内への入れ込み前の状態においては、この入れ込み方向に沿った向きから雄部材１を見た状態において、互いの突起１２をオーバーラップさせず、一対の挟持用脚部１１、１１間への紐状ないしは帯状物Ｗの端部Ｗａの入れ込みは支障なくなせる一方、この挟持用脚部１１を雌部材２内に入れ込み切った状態においては、この入れ込み方向に沿った向きから雄部材１を見た状態において、互いの突起１２をオーバーラップさせて、一対の挟持用脚部１１、１１間にある紐状ないしは帯状物Ｗの端部Ｗａに互いの突起１２を突き刺し、あるいは、突き立てるようになっている。また、図示の例にあっては、一方の挟持用脚部１１における他方の挟持用脚部１１に向き合った側と反対の外面部と前記溝状部１４の溝底までの間隔が、他方の挟持用脚部１１における一方の挟持用脚部１１に向き合った側の内面部とこれと反対の外面部間の間隔とほぼ等しいが、一方の挟持用脚部１１における他方の挟持用脚部１１に向き合った側と反対の外面部と溝状部１４の溝口までの間隔はこれより大きいため、この一方の挟持用脚部１１を他方の挟持用脚部１１とほぼ同じように弾性変形させるようにする観点から、一方の挟持用脚部１１と基部片１３との連接箇所であって、この一方の挟持用脚部１１における他方の挟持用脚部１１に向き合った側に、前記溝状部１４の溝壁の一部を切り欠くようにした切欠部１５を形成させている。
【００４６】
また、この実施の形態にあっては、雄部材１の挟持用脚部１１を、紐状ないしは帯状物Ｗにテンションが作用された際に、このテンションの作用に伴う雌部材２の引き出し開口２０側に向けた挟持用脚部１１の移動を弾性変形しながら許容させる連接体１６を介して頭部１０に連接させている。
【００４７】
これにより、この実施の形態にあっては、こうしたテンションが作用された際に、雌部材２内への入れ込みにより撓み込まされた挟持用脚部１１によって紐状ないしは帯状物Ｗを雌部材２内で把持している雄部材１の挟持用脚部１１を、このテンションによって雌部材２内から抜け出そうとする紐状ないしは帯状物Ｗと一緒に同じ向きに移動させることができ、こうしたテンションによっても紐状ないしは帯状物Ｗの端部Ｗａに対する挟持用脚部１１の把持位置にズレを生じさせることがなく、この端部Ｗａの把持状態を安定的に維持させることができる。また、こうしたテンションの作用がなくなった場合には、前記連接体１６の弾性復帰により、挟持用脚部１１を再び所期の位置に復帰させることができる。
【００４８】
図示の例にあっては、前記連接体１６を、前記基部片１３における挟持用脚部１１との連接側と反対の側であって、この基部片１３の長さ方向ほぼ中程の位置にバネ一端１６ｂを一体に連接させると共に、前記頭部１０におけるドーム状に構成された側と反対の側の面のほぼ中央部にバネ他端１６ｃを一体に連接させ、かつ、このバネ一端１６ｂとバネ他端１６ｃとの間における二カ所で屈曲されて蛇行状に形成されたバネ状屈曲片１６ａによって構成させている。
【００４９】
そして、図示の例にあっては、紐状ないしは帯状物Ｗに対し前記のようにテンションが作用されると、前記バネ状屈曲片１６ａの二カ所の屈曲箇所１６ｄ、１６ｄとバネ一端１６ｂおよびバネ他端１６ｃとの間のピッチを広げるようにこのバネ状屈曲片１６ａが弾性変形して、挟持用脚部１１の前記移動を許容するようになっている。（図３）
【００５０】
なお、図示の例にあっては、一対の挟持用脚部１１、１１の先端であって、他方の挟持用脚部１１に向き合わない側に、挟持用脚部１１の基部片１３との連接側に掛合面１７ａを向けた位置決め突起１７が形成されていると共に、雌部材２の締め込み用内壁部２２の引き出し開口２０側の終端と、この引き出し開口２０の縁部との間に、この引き出し開口２０側に段差面２４ａを向けた段部２４が形成されており、雌部材２内に雄部材１の挟持用脚部１１を入れ込み切ることに伴って、前記位置決め突起１７の掛合面１７ａが前記段差面２４ａに引き出し開口２０側から引っかかるようになっている。これにより、前記テンションが作用されなくなった後に、前記連接体１６の弾性復帰によって必要以上に挟持用脚部１１が入れ込み開口２１側に移動してしまうことがないようになっている。
【００５１】
図示の例では、雌部材２への雄部材１の挟持用脚部１１の入れ込みに伴って、この位置決め用突起１７を主として前記締め込み用内壁部２２に接しさせて、この挟持用脚部１１が撓み込まされるようになっており、この入れ込みをスムースならしめる観点から、位置決め用突起１７における挟持用脚部１１の先端に向けられた側には、この位置決め用突起１７の突き出し端に近付くに連れてこの位置決め用突起１７を細める向きに掛合面１７ａ側に次第に傾斜した傾斜面１７ｂが形成されている。この位置決め用突起１７は、この位置決め用突起１７の突き出し端が前記段差面２４ａの先に入り込んだ位置での挟持用脚部１１側の若干の弾発によって、かかる段差面２４ａに引っかかるようになっている。
【００５２】
また、この実施の形態にあっては、雄部材１の頭部１０と雌部材２の入れ込み開口２１側とのいずれか一方に、これらの他方に形成された被掛合部２５に対し、雌部材２内に雄部材１の挟持用脚部１１を入れ込み切った位置で掛合される掛合部１８ａを形成させている。
【００５３】
これにより、この実施の形態にあっては、雄部材１の二以上の挟持用脚部１１、１１…間に紐状ないしは帯状物Ｗの端部Ｗａを入れ込ませた状態で、雌部材２内にこの挟持用脚部１１を入れ込み切っることにより作出されたこの端部Ｗａをカバーさせた状態を、安定的に維持させることができる。
【００５４】
図示の例では、雄部材１の頭部１０における、前記ドーム状をなす面と反対の側にある面であって、前記連接体１６を挟んだ両側にそれぞれ、雌部材２に雄部材１の挟持用脚部１１を入れ込み切る直前の段階において、この入れ込み開口２１から雌部材２内に入り込む突片１８が設けられている。この突片１８は、前記連接体１６に向き合わない側を雌部材２の短寸側の内壁部２３に向き合わせるようにして雌部材２内に入れ込まれるようになっている。

[0030]
When tension is applied to the string-like or belt-like object W, the male member 1 holding the end portion Wa of the string-like or belt-like object W in the female member 2 by the clamping leg 11 is also pulled out to the opening 20 side. However, when such a force is applied, the clamping leg 11 is bent more in the direction of clamping the end portion Wa by the tightening inner wall 22. Therefore, the end portion Wa that is sandwiched does not easily come out between the sandwiching leg portions 11 during the tension operation, that is, from the inside of the female member 2, and the cover state of the end portion Wa is stably maintained. Can be secured.
[0031]
In the illustrated example, the female member 2 is configured to have a flat cylindrical shape. That is, in the illustrated example, the female member 2 is configured so that both the outer shape and the inner shape are substantially elliptical at almost any position in the cross section in the direction orthogonal to the cylinder axis. The inner and outer walls on the short side and the inner and outer walls on the long side are provided.
[0032]
On the other hand, the male member 1 is configured to have a pair of clamping legs 11, 11. In the illustrated example, the surface of the head 10 of the male member 1 on the side connected to the pair of sandwiching legs 11, 11 is abutted against the edge around the insertion opening 21 of the female member 2. The holding leg 11 of the male member 1 can be inserted into the female member 2 up to the position, and this position is a position where the male member 1 is fully inserted into the female member 2. In addition, the male member 1 has the pair of sandwiching leg portions 11, 11 having the outer side of one end portion Wa thereof in contact with the inner wall portion 23 on the short side of the female member 2, and the pair of sandwiching legs 11 The sandwiching leg portion 11 is inserted into the female member 2 while the outside of the other tip end portion Wa of the leg portions 11 and 11 is in contact with the inner wall portion 23 on the other short side of the female member 2. ing.

[0033]
In this embodiment, the tightening inner wall portion 22 of the female member 2 is inclined so as to reduce the internal space of the female member 2 as it approaches the drawer opening 20.
[0034]
As a result, the holding leg portion 11 of the male member 1 inserted into the female member 2 can be gradually bent larger as the amount of insertion into the female member 2 increases, and the male member into the female member 2 can be bent. It is possible to smoothly insert one clamping leg 11.
[0035]
Further, when tension is applied to the string-like or band-like object W, the opening Wa is also drawn out to the male member 1 holding the end portion Wa of the string-like or band-like object W in the female member 2 by the clamping leg 11. A force directed toward the side 20 is applied, and when such a force is applied, the clamping leg 11 is more tightly connected to the end portion Wa by the tightening inner wall 22 inclined in this way. Since the end portion Wa is clamped in the direction to be clamped, the clamped end portion Wa is not easily pulled out from between the clamping leg portions 11, that is, from the inside of the female member 2. The cover state of the end portion Wa can be stably secured.
[0036]
In the illustrated example, on the insertion opening 21 side of the female member 2, the distance between the pair of short side inner wall portions 23 of the female member 2 is the tip of the pair of clamping legs 11, 11 of the male member 1. Is slightly larger than the dimension between the outer surface parts (more specifically, in the illustrated example, between the protruding ends of positioning protrusions 17 to be described later), but the distance between the pair of short side inner wall parts 23 is from here The tightening inner wall portion 22 is configured to gradually narrow toward the drawer opening 20 side.
[0037]
Further, in this embodiment, the clamping leg portion 11 of the male member 1 is provided with a projection 12 that functions as a spike for the string-like or band-like object W to be clamped.
[0038]
Thus, two or more sandwiching legs 11, 11... In the illustrated example, the pair of sandwiching legs 11, 11 is inserted into the end portion Wa of the string-like or belt-like object W between the pair of sandwiching legs 11, 11. When the leg portion 11 is inserted into the female member 2, the projection 12 is pierced or projected to the end Wa by the sandwiching leg portion 11 bent as described above. It is possible to hold the end portion Wa more reliably by the protrusion 12.
[0039]
In the illustrated example, the head portion 10 of the male member 1 is configured so as to form a dome shape on the side opposite to the protruding side surface of the sandwiching leg portion 11. The head 10 is configured to close the insertion opening 21 of the female member 2 at a position where the female member 2 is fully inserted.
[0040]
Further, in the illustrated example, the pair of sandwiching leg portions 11 and 11 are opposed to each other by the base piece 13 extending between the end portions Wa on the side opposite to the distal ends of the pair of sandwiching leg portions 11 and 11. Are connected to each other at the end Wa on the side of the side. That is, the pair of sandwiching leg portions 11 and 11 and the base piece 13 are integrated so as to form a U-shape as a whole. Each of the pair of sandwiching legs 11, 11 is configured to be elastically deformed so that the connection side with the base piece 13 is generally the center and the tip side is closer to the other sandwiching leg 11. Has been.
[0041]
Further, each of the pair of sandwiching leg portions 11, 11 includes the projection 12 on the side facing the other sandwiching leg portion 11.
[0042]
In the illustrated example, one of the pair of sandwiching leg portions 11, 11 has a base portion from the distal end side on the side facing the other sandwiching leg portion 11 of the one sandwiching leg portion 11. A groove-like portion 14 extending toward the connection side with the piece 13 is formed. In one of the pair of sandwiching leg portions 11, 11, the protrusions 12 are formed on both sides of the groove-shaped portion 14. The projections 12 are provided on both sides of the groove-like portion 14 to form a pair, and in the example shown in the drawing, the pair of projections 12, 12 is a pair of the clamping leg portions 11, 11. It is provided at two places with a gap in one length direction.
[0043]
On the other hand, one projection 12 is provided on the other of the pair of sandwiching legs 11, 11 on the side of the other sandwiching leg 11 facing the one sandwiching leg 11. The protrusion 12 provided on the other holding leg 11 protrudes from the substantially intermediate position of the other holding leg 11 in the width direction toward the one holding leg 11. . Further, in the illustrated example, the projections 12 of the other clamping leg 11 are provided at two positions on the one clamping leg 11 in the length direction of the clamping leg 11. It is provided between the pair of protrusions 12 and 12 so that the protruding end is located.
[0044]
In the illustrated example, each of the protrusions 12 provided on the pair of sandwiching legs 11 and 11 is configured to have a conical outer shape with sharpened protruding ends, As the projection 12 moves from the base portion toward the projecting end, the projection 12 gradually projects so as to incline away from the tip of the sandwiching leg portion 11.
[0045]
Thus, in the example shown in the drawing, after the end portion Wa of the string-like or band-like object W is inserted between the pair of sandwiching leg portions 11, 11, the pair of sandwiching leg portions 11, 11 is Each of the protrusions 12 can be firmly bitten into the string-like or belt-like object W by the holding leg portion 11 bent by being inserted into the female member 2. Further, since each of the protrusions 12 is inclined as described above, when the tension is applied to the string-like or band-like object W, the protrusion 12 bites into the string-like or band-like object W deeper. Therefore, the tension state of the string-like or belt-like object W is more difficult to be released. Further, the projection 12 of the one sandwiching leg 11 and the projection 12 of the other sandwiching leg 11 are different from each other in the length direction of the sandwiching leg 11 and the end portion Wa of the string-like or band-like object W is formed. In the width direction of the sandwiching leg 11, the projection 12 of the other sandwiching leg 11 has a string or band shape between the pair of projections 12 in the width direction of the sandwiching leg 11. Since the end portion Wa of the object W is pierced or protruded, the end portion Wa of the string-like or belt-like object W can be firmly sandwiched by the pair of sandwiching leg portions 11, 11. It has become. Further, since the groove-shaped portion 14 is formed in one of the sandwiching leg portions 11, the end portion Wa of the string-like or band-like object W deformed by the piercing of the protrusion 12 or the protrusion. A part of the end cover can be escaped by the groove-like portion 14, whereby the entire end cover can be made compact. In the illustrated example, the projection 12 of one clamping leg 11 and the projection 12 of the other clamping leg 11 are oriented along this insertion direction in the state before being inserted into the female member 2. In the state where the male member 1 is viewed from the side, the protrusions 12 do not overlap each other, and the insertion of the end portion Wa of the string-like or belt-like object W between the pair of sandwiching leg portions 11 and 11 can be made without any trouble. In the state where the holding leg 11 is fully inserted into the female member 2, in the state where the male member 1 is viewed from the direction along the insertion direction, the protrusions 12 are overlapped to form a pair of holding members. The protrusions 12 are pierced or protruded into the end portion Wa of the string-like or belt-like object W between the leg portions 11, 11. In the example shown in the drawing, the distance between the outer surface portion of one clamping leg 11 opposite to the side facing the other clamping leg 11 and the groove bottom of the groove-like portion 14 is the other. The distance between the inner surface portion of the sandwiching leg portion 11 facing the sandwiching leg portion 11 and the outer surface portion opposite thereto is substantially equal, but the other sandwiching leg portion 11 of the one sandwiching leg portion 11 is the same. The gap between the outer surface opposite to the side facing the groove and the groove opening of the groove-like portion 14 is larger than this, so that the one holding leg 11 is elastically deformed in substantially the same manner as the other holding leg 11. From the point of view, the groove-like portion is connected to the one holding leg 11 and the base piece 13 on the side of the one holding leg 11 facing the other holding leg 11. 14 is formed with a notch 15 in which a part of the groove wall is notched. That.
[0046]
Further, in this embodiment, when a tension is applied to the string-like or belt-like object W of the holding leg portion 11 of the male member 1, the pull-out opening 20 of the female member 2 accompanying the action of the tension is applied. It is connected to the head 10 via a connecting body 16 that allows movement of the holding leg 11 toward the side while allowing elastic deformation.
[0047]
Thus, in this embodiment, when such a tension is applied, the string-like or belt-like object W is moved into the female member 2 by the sandwiching leg portion 11 bent by being inserted into the female member 2. The gripping leg portion 11 of the male member 1 gripped in the step can be moved in the same direction together with the string-like or band-like object W to be pulled out of the female member 2 by this tension. The gripping position of the holding leg portion 11 with respect to the end portion Wa of the string-like or band-like object W is not displaced, and the gripping state of the end portion Wa can be stably maintained. Further, when the action of such tension is lost, the clamping leg 11 can be returned to the intended position again by the elastic return of the connecting body 16.
[0048]
In the example shown in the drawing, the connecting body 16 is on the side of the base piece 13 opposite to the connecting side with the clamping leg 11, and at a position approximately in the middle of the length of the base piece 13. The spring one end 16b is integrally connected, and the spring other end 16c is integrally connected to the substantially central portion of the head 10 on the side opposite to the dome-shaped side. The spring-like bent piece 16a is bent in two places between the other end 16c of the spring and is formed in a meandering shape.
[0049]
In the illustrated example, when the tension is applied to the string-like or belt-like object W as described above, the two bent portions 16d and 16d, the spring one end 16b and the spring-like bent piece 16a This spring-like bent piece 16a is elastically deformed so as to widen the pitch with the other end 16c, and the movement of the sandwiching leg portion 11 is allowed. (Figure 3)
[0050]
In the example shown in the figure, the end of the pair of sandwiching legs 11, 11 is connected to the base piece 13 of the sandwiching leg 11 on the side that does not face the other sandwiching leg 11. A positioning projection 17 is formed with the engaging surface 17a facing the side, and between the end of the inner wall portion 22 for tightening the female member 2 on the side of the drawer opening 20 and the edge of the drawer opening 20 A stepped portion 24 having a stepped surface 24 a facing the drawer opening 20 is formed, and the engaging surface 17 a of the positioning projection 17 is inserted in accordance with the insertion of the clamping leg portion 11 of the male member 1 into the female member 2. Is caught on the stepped surface 24a from the drawer opening 20 side. As a result, after the tension is no longer applied, the clamping leg 11 is not moved to the insertion opening 21 side more than necessary due to the elastic return of the connecting body 16.
[0051]
In the illustrated example, with the insertion of the clamping leg portion 11 of the male member 1 into the female member 2, the positioning projection 17 is mainly brought into contact with the inner wall portion 22 for clamping, and the clamping leg portion 11. From the viewpoint of smoothing the insertion, the side of the positioning projection 17 facing the tip of the clamping leg 11 approaches the protruding end of the positioning projection 17. Accordingly, an inclined surface 17b that is gradually inclined toward the engaging surface 17a is formed in a direction in which the positioning projection 17 is narrowed.
