Description

【０００１】
【発明の属する技術分野】
本発明は、コントロールケーブルの締結部材に関するものであり、特に、コントロールケーブルの長さを調節することができる締結部材に関する。
【０００２】
【従来の技術】
コントロールケーブルは、例えば、自動車などのトランスミッション、アクセル、スロットル、クラッチ、ブレーキ、また、ウィンドウレギュレータ等の操作に用いられている。
【０００３】
上記の各種装置にコントロールケーブルを用いる場合には、一端を従動側装置（例えばアクセルペダル）に、他端を駆動側装置（例えばスロットル）に固定する。したがって、コントロールケーブルを各種装置に設置する際には、コントロールケーブルの長さを調節することにより、取り付ける必要がある。
【０００４】
コントロールケーブルの長さを調節できる装置を開示する文献に、特許文献１がある。特許文献１では、筒形部材に、ケーブルの端部に形成された鋸歯列部材を軸方向に挿入し、ケーブルの長さを調整後、筒形部材に形成された窓孔から係止部材を軸芯方向へ挿入することにより係止部材と鋸歯列部材とを係止し、ケーブルの長さを固定する。このとき、係止部材の側面に形成されたくさび状の突部が、筒形部材に形成された割り溝に嵌合する（特許文献１、図６参照）ことにより、係止部材は筒形部材に挿着される。
【０００５】
特許文献１の装置は、係止部材に力を加えると突部が容易に移動するため、明細書には記載されていないが、係止部材を固定する別部材のストッパーを有する。このストッパーにより搬送中に係止部材と筒形部材とが嵌合したり、コントロールケーブルの使用中に係止部材と筒形部材との嵌合が解除されるなど、誤操作を防止することができる。
【０００６】
しかしながら、ストッパーを用いると、係止部材を筒形部材へ着脱する際にストッパーを固定または解除する必要があるので操作回数が増加すると共に、装置の部品数が多くなるという問題がある。

【発明が解決しようとする課題】
本発明は、簡単な部品構成でありながら誤操作の少ないコントロールケーブルの締結部材を提供することを課題とする。
【０００９】
【課題を解決するための手段】
本発明のコントロールケーブルの締結部材は、外周に第一係止歯をもつ棒状の係止端部を有するコントロールケーブルの該係止端部が挿着される挿着孔と、該挿着孔の奥側で該挿着孔と交差する窓孔と、を有する締結本体と、前記窓孔に着脱自在で、かつ前記第一係止歯と挿着時に係止する第二係止歯を有するキー部材と、を有するコントロールケーブルの締結部材であって、前記締結本体および前記キー部材は、該キー部材の挿着および脱着により該締結本体と該キー部材とを係合および開合する主ロック部と、前記キー部材に設けられた操作部により前記締結本体と前記キー部材との固定と解除を行う副ロック部とを有することを特徴とする。
【００１０】
上記構成によれば、キー部材に設けられた操作部を作動させなければ副ロック部の固定・解除ができないので、別部材を用いることなく誤操作による締結本体とキー部材との着脱を防止できる。そのため、キー部材が締結本体に挿着または脱着した状態を保持するための別の部品や、その部品の固定や解除が不要となる。
【００１１】
前記主ロック部は、前記締結本体および前記キー部材に設けられ互いに嵌合する凹部および凸部の一方および他方からなるのが好ましい。さらに、前記凹部および／または前記凸部は弾性部材に設けられているのが好ましく、また、前記凹部および前記凸部は断面扇形状であるのが好ましい。凹部と凸部が弾性部材に設けられていると、弾性部材の撓みの程度を適宜調節することによりキー部材の操作量や操作時の負荷を所望の大きさに設定することができる。また、凹部および凸部が断面扇形状であると、作動荷重以下の力を加えた場合でも、容易に移動することがないので、誤操作による締結本体とキー部材との着脱を防止できる。
【００１２】
前記凹部は、軸方向に延びる溝状部からなるのが好ましい。そして、前記溝状部は、前記締結本体に前記キー部材を仮挿着する第一溝状部と本挿着する第二溝状部とから成り、両者は互いに平行であるのが好ましい。第一溝状部と第二溝状部とが互いに平行であると、同一方向への二段階の動きにより、キー部材が締結本体に仮に固定された仮挿着の状態や、第一係止歯と第二係止歯とが係止した本挿着の状態に着脱することができる。
【００１３】
前記副ロック部は、前記締結本体および前記キー部材に設けられ互いに係合する突起部および係合部の一方および他方からなるのが望ましい。また、前記突起部および前記係合部は、断面方形状であるのが望ましい。断面方形状であれば、操作部を作動させなければ、突起部と係合部との係合が解けることはないので、誤操作による締結本体とキー部材との着脱を防止できる。
【００１４】
また、前記操作部は、可撓性を有する板状であるのが望ましい。操作部が可撓性を有する板状であると、撓みの程度を適宜調節することにより操作部の操作量や操作時の負荷を所望の大きさに設定することができる。
【００１５】
前記締結本体は、全体が筒状であるのが好ましい。また、前記キー部材は、前記締結本体へ挿着時に、前記締結本体と一体となって全体として筒状をなすのが好ましい。筒状の形状を有する締結本体にキー部材を挿着した時に、筒状の締結本体の周面からキー部材が突出することなく一体となるので、締結部材の設置場所をとらず、見た目にも優れる。
【００１６】
前記キー部材は、Ｕ字形状であるのが好ましい。そして、前記キー部材は、前記Ｕ字形状の奥側の内周面に前記第一係止歯と係止する前記第二係止歯を有するのが好ましい。
【００１７】
また、前記第一係止歯は、前記係止端部の外周面をリング状に一周し軸方向に延びる凹凸からなるのが望ましい。さらに、前記締結本体は、一端に他の部材を係止する係止部を有するのが望ましい。
【００１８】
【発明の実施の形態】
本発明のコントロールケーブルの締結部材は、締結本体とキー部材とを有する。
【００１９】
締結本体は、コントロールケーブルの係止端部が挿着される挿着孔と、挿着孔の奥側で挿着孔と交差する窓孔とを有する。
【００２０】
締結本体に挿着されるコントロールケーブル（以下「ケーブル」と記載する）は、一般にコントロールケーブルの内索として用いられているケーブルであれば特に限定はないが、外周に第一係止歯をもつ棒状の係止端部を有する。
【００２１】
係止端部は、締結部材として望まれる機械的強度などを考慮して材料を適宜選択すればよい。また、係止端部の形状や大きさも、締結部材の大きさに合わせて適宜選択すればよい。
【００２２】
係止端部は、その外周に第一係止歯を有する。第一係止歯は、キー部材が有する第二係止歯（後述）と係止した場合に、少なくともケーブルの軸方向への移動が規制できる形状であればよい。そのため、係止端部には、その外周面をリング状に一周し軸方向に延びる凹凸を、第一係止歯として形成しても良い。具体的には、雄螺子や軸方向に等間隔に形成された蛇腹状の凹凸などが挙げられる。
【００２３】
さらに、係止端部の端部には、第一係止歯の外径よりも大きいガイド部を形成しても良い。ガイド部を形成することにより、係止端部を締結本体の挿着孔へ挿入する際に、第一係止歯が挿着孔に接触するのを防ぐことにより、係止端部を挿着孔へ滑らかに挿入することができ、適切な位置まで容易に挿入することができる。また、係止端部の先端部には、係止端部が締結本体の挿着孔から抜け出すのを防止するための突起を形成しても良い。
【００２４】
さらに、係止端部の他端部には、ケーブルのプリテンション工程時に用いる、段差部を有するのが好ましい。プリテンション工程とは、ケーブルの両端部に引っ張り荷重を加えてケーブルの初期伸びを除去する工程である。
【００２５】
締結本体は、締結部材として望まれる機械的強度などを考慮して材料を適宜選択すればよいが、好ましくはポリアセタール、ナイロン、ポリプロピレンなどの樹脂製である。締結本体の形状に特に限定はないが、全体が筒状であるのが好ましい。また、締結本体は、一端に、ピン、ボルト、リベットなどの他の部材を係止することができる係止部を有するのが望ましい。
【００２６】
締結本体は、ケーブルの係止端部を挿着する挿着孔を有する。挿着孔の形状や大きさは、係止端部を挿着できれば特に限定はなく、係止端部の形状と大きさに合わせて適宜選択すればよい。また、締結本体は、挿着孔の奥側で挿着孔と交差する窓孔を有する。挿着孔の奥側とは、挿着孔の端部すなわちケーブルの出入り口となる部分以外の部分を指す。窓孔は、挿着孔の奥側で挿着孔と交差する位置にあれば、その形状や大きさに特に限定はない。
【００２７】
キー部材は、締結本体の窓孔に着脱自在で、かつケーブルの第一係止歯と挿着時に係止する第二係止歯を有する。
【００２８】
キー部材は、締結部材として望まれる機械的強度などを考慮して材料を適宜選択すればよいが、好ましくはポリアセタール、ナイロン、ポリプロピレンなどの樹脂製である。キー部材は、締結本体の窓孔に挿着できれば、その大きさに特に限定はない。また、キー部材は、Ｕ字形状であるのが好ましく、Ｕ字形状の内周面に第二係止歯を有するのが好ましい。
【００２９】
第二係止歯は、ケーブルの係止端部に形成された第一係止歯と係止した場合に、少なくともケーブルの軸方向への移動が規制できる形状であればよい。例えば、第一係止歯が雄螺子であれば第二係止歯にはその雄螺子と螺合する雌螺子を、第一係止歯が蛇腹状の凹凸であれば第二係止歯にはその凹凸と嵌合する凹凸を用いれば、ケーブルの軸方向への移動が規制できる。また、多数の突起とその突起と係止する窪みとが係止する形態の係止歯の組み合わせであれば、ケーブルの軸方向への移動と共に回動も規制できる。
【００３０】
本発明のコントロールケーブルの締結部材において、締結本体およびキー部材は、キー部材の挿着および脱着により締結本体とキー部材とを係合および開合する主ロック部を有する。
【００３１】
主ロック部は、締結本体とキー部材とを着脱自在に係合および開合できる形態であれば特に限定はないが、締結本体およびキー部材に設けられ、互いに嵌合する凹部および凸部の一方および他方をそれぞれ有するのが好ましい。凹部および凸部は、互いに嵌合すれば締結本体とキー部材のどちらに設けられてもよく、その数にも限定はない。
【００３２】
また、凹部・凸部の少なくとも一方は、弾性部材に設けられているのが好ましい。弾性部材は、締結本体にキー部材を挿着または脱着する際にかかる力により撓みを生じる。弾性部材に撓みが生じることで、凹部と凸部を滑らかに移動させ、嵌合することができる。また、撓みの程度を調節することで、キー部材の操作量や操作時の荷重を所望の大きさに設定することができる。操作時の荷重を小さくしたい場合には、弾性部材の厚みを薄くして撓みを生じやすくしたり、撓みを生じやすい弾性部材を選択するなどして適宜調節すればよい。
【００３３】
凹部および凸部は、断面扇形状であるのが好ましい。凹部および凸部の形状を断面扇形状とした場合の効果を、他の形状とした場合と比較して説明する。図１は、凹部を有する部材および凸部を有する部材の形状と、凸部を有する部材を矢印の方向へ負荷した場合のＰ−δ特性を示す。図１（Ｉ）は半円状、（ＩＩ）はくさび状の断面をもつ凹部および凸部を有する部材を用いている。位置を固定された凹部を有する部材に凸部が嵌合した状態から、凸部を有する部材を図の矢印の方向へ負荷し、凸部を有する部材に撓みを生じさせることにより凸部を矢印の方向へ移動する。また、Ｐ−δ特性を示すグラフにおいて、Ｐは負荷荷重、δは移動距離、Ｐ_Ｉ，Ｐ_ＩＩは作動荷重である。
【００３４】
本発明の構成に相当する（Ｉ）では、負荷荷重がＰ_Ｉに達するまでのＰ−δ特性のグラフの傾きが、（ＩＩ）よりも急で、作動荷重以下での凸部を有する部材の撓みが小さく移動距離が微小である。そのため、凹部と凸部との離脱強度も高くなる。したがって、凹部および凸部の形状を断面扇形状にする構成は、搬送中などに起こりうる誤操作による着脱の防止に有効である。なお、上記とは逆に、凸部を有する部材を図１の矢印とは反対方向へ負荷した場合も、同様である。
【００３５】
断面扇形状を有する凹部および凸部は、互いに嵌合する形状であれば特に限定はなく、断面半円形で蒲鉾形状の凸部と溝状の凹部との組み合わせや、半球状の凸部と半球状面を有する凹部との組み合わせ等、いずれでもよい。
【００３６】
また、着脱自在に嵌合する断面扇形状の凹部および凸部は、１つの凸部（または凹部）に対して複数の凹部（または凸部）を有するものでもよい。より好ましくは、１つの凸部に対して２つの凹部を有するものである。１つの凸部に対して２つの凹部を有する構成であれば、二段階の嵌合が可能となる。
【００３７】
本発明のコントロールケーブルの締結部材は、キー部材に設けられた操作部により締結本体とキー部材との固定と解除を行う副ロック部を有する。
【００３８】
副ロック部は、締結本体とキー部材とを係合および開合できる形態であれば特に限定はないが、操作部により締結本体とキー部材との固定と解除を行う点において、主ロック部と異なる。副ロック部は、締結本体および前記キー部材に設けられ互いに係合する突起部および係合部の一方および他方からなるのが望ましい。突起部および係合部は、互いに嵌合すれば締結本体とキー部材のどちらに設けられてもよく、その数にも限定はない。突起部と係合部は、締結本体とキー部材とを固定する際にも、固定を解除する際にも、操作部を用いなければ固定・解除が行えないものとする。そのため、突起部および係合部は、断面方形状であるのが望ましい。
【００３９】
操作部は、キー部材に設けられ、操作部を作動させることで締結本体とキー部材との固定と解除を行うことができれば、その形態に限定はないが、可撓性を有する板状であるのが望ましい。操作部に力を加えることにより撓みを生じさせることにより、副ロック部の突起部と係合部とを係合させたり解除したりできる。また、操作部に力を加え易くするために、操作部に取っ手を設けたり、操作部に力を加えたままキー部材の着脱が可能となる専用の器具を用いてもよい。
【００４０】
上記以外にも、締結本体の窓孔に挿着されたキー部材が突出するのを防ぐためにキー部材に締結本体と係合するような突起を設けたり、挿着後の締結本体とキー部材との間のがたつきを少なくするために窓孔の入り口部分とキー部材とが係合するような凹凸部分を設けたりすることができる。
【００４１】
【実施例】
（実施例１）
本発明のコントロールケーブルの締結部材の一実施例を、図を用いて説明する。
【００４２】
図２〜５は、本発明のコントロールケーブルの締結部材の締結本体の斜視図および平面図と断面図である。図６〜９は、本発明のコントロールケーブルの締結部材のキー部材の斜視図および平面図と断面図である。
［締結本体］
図２は、本発明のコントロールケーブルの締結部材の締結本体の斜視図である。また、図３は本発明のコントロールケーブルの締結部材の締結本体の平面図であって、図３のＡ−Ａ断面図を図４に、Ｂ−Ｂ断面図を図５に示す。
【００４３】
本実施例のコントロールケーブルの締結部材において、締結本体２０は、ガラス繊維強化ナイロン樹脂製である。締結本体２０は、全体として円筒形をなす円筒部材２８と、円筒部材２８の一端に連結したドーナツ形状をなす係止部２９からなる。円筒部材２８と係止部２９とは同じ外径を有し、互いに軸方向を垂直にして連結されている。円筒部材２８と係止部２９との連結部分には、空間部２７を設けてある。この空間部２７は、後に説明するケーブルの長さを調整するのに必要な空間であり、空間部２７の軸方向の距離の分だけケーブルの長さを調整できる。
【００４４】
円筒部材２８の円筒の中空部分は、挿着孔２１である。この挿着孔２１は、後述するケーブル４０の端部を挿着する孔である。そして、挿着孔２１は、円筒部材２８の軸方向に平行に延びており、空間部２７と連通する。
【００４５】
円筒部材２８は、挿着孔２１とその奥側で交差し、円筒部材２８を貫通する窓孔２２を有する。窓孔２２は、後述するキー部材３０を着脱可能に挿着する孔である。窓孔２２は、円筒部材２８の軸方向に平行かつ互いに平行に対向する２つの面２２１と、面２２１に垂直かつ互いに平行に対向する２つの面２２６を有する。
【００４６】
２つの面２２１は、それぞれ、互いに平行な第一溝状部２０１と第二溝状部２０２とを有する。第一溝状部２０１と第二溝状部２０２は、円筒部材２８の軸方向と平行となっている。なお、キー部材３０は４つの面２２１，２２６で形成された窓孔２２の長方形の窓孔口２２２から挿入されるが、窓孔口２２２に近い方が第一溝状部２０１である。また、向かい合う２つの第一溝状部２０１と、向かい合う２つの第二溝状部２０２は、窓孔口２２２から互いに同じ距離にある。そして、第一溝状部２０１は半円、第二溝状部２０２は４分の１円の円周部分を内周面とし、その半円と４分の１円は同一半径である。
【００４７】
窓孔２２の窓孔口２２２は、面２２１側に４つの凹部２２３を有する。また、２つの面２２６は、それぞれ長方形断面の係合溝２２８を有する。係合溝２２８は、窓孔口２２２よりも距離を隔てた位置から溝状部２０１，２０２と垂直方向で下方へに延びている。上記の第一溝状部２０１と第二溝状部２０２、凹部２２３、係合溝２２８は、それぞれキー部材３０の一部と係合する。なお、図示しないが、長方形の窓孔口２２２は、面２２６側の辺に面取りが施されている。
【００４８】
［キー部材］
図６は、本発明のコントロールケーブルの締結部材のキー部材の斜視図である。また、図７は本発明のコントロールケーブルの締結部材の締結本体の平面図であって、図７のＣ−Ｃ断面図を図８に、Ｄ−Ｄ断面図を図９に示す。
【００４９】
本実施例のコントロールケーブルの締結部材において、キー部材３０は、ガラス繊維強化ナイロン樹脂製である。キー部材３０は、全体としてＵ字形状であり、締結本体２０の円筒部材２８の外周面と同一の曲率半径の外面をもった天井部３１と、天井部３１から直線的に延出する２つの脚部３６とからなる。そして、脚部３６の端面は、天井部３１の外面と同一円周上にある。また、Ｕ字形状のキー部材３０の内周面、すなわち、天井部３１と２つの脚部３６とで形成される空間の内周面には、雌螺子３１１が形成されている。
【００５０】
キー部材３０の外面をなす２つの脚部３６の側面は、それぞれ外側に向かって突出した断面半円状の凸部３０１を有する。この凸部３０１は、締結本体２０の第一溝状部２０１および第二溝状部２０２と嵌合する。すなわち、第一溝状部２０１と第二溝状部２０２、凸部３０１で主ロック部が構成される。凸部３０１は、脚部３６の側面から薄片状に切り出された形状をもつ弾性片３６１の先端に位置する。弾性片３６１は薄片状で、かつ、弾性片３６１の周囲には隙間３６７が設けてあるので、弾性片３６１の先端に位置する凸部３０１に力が加わると弾性片３６１が隙間３６７側へ撓む。
【００５１】
また、脚部３６のそれぞれの側面は、天井部３１の外面に連なって延出する突出部３１３を両端部に有する。
【００５２】
キー部材３０のＵ字形状を有する側面は、断面方形状の突起部３３８をもつ。突起部３３８を有する側面は薄片状に切り出された板状の操作部３１８であり、天井部３１から垂直に隙間３１７が設けてある。操作部３１８は、隙間３１７の方へ力を加えると撓みを生じるので、操作部３１８を動かすことにより突起部３３８が移動する。突起部３３８は、締結本体２０の係合溝２２８と係合する。すなわち、操作部３１８、突起部３３８および係合溝２２８で副ロック部が構成される。
【００５３】
［コントロールケーブル］
ケーブル４０は、ワイヤケーブル４２と係止端部４１を有する（図１１の軸方向の断面図を参照）。係止端部４１は筒状の金属製で、外周面には雄螺子４１１を有する。この雄螺子４１１は、キー部材３０の内周面の雌螺子３１１と螺合する形状である。
【００５４】
ワイヤケーブル４２は、その端部を係止端部４１の筒内に挿入し、その部分をかしめてワイヤケーブル４２と係止端部４１とを固定している。
【００５５】
また、係止端部４１のワイヤケーブル４２の挿入側の端部には、その外周面にケーブルのプリテンション工程時に用いる、治具を引っ掛けるための突起部４４を有する。突起部４４は、係止端部４１と同軸的に円周状に形成されている。
【００５６】
［締結操作］
図１０および図１１を用いて、本実施例のコントロールケーブルの締結部材の締結操作を説明する。
【００５７】
ケーブル４０の係止端部４１は、締結本体２０の挿着孔２１より挿入され、係止端部４１の先端部には、空間部２７において挿着孔２１よりも外径の大きいＥリング４１２が固定されている（図１１の軸方向の断面図を参照のこと。）。
【００５８】
キー部材３０は、締結本体２０の窓孔口２２２より軸芯方向へ挿入される。この際、キー部材３０の凸部３０１は窓孔２２の面２２１よりも外側へ突出しているので、凸部３０１は面２２１に相対的に押されることにより弾性片３６１が隙間３６７の方へ撓む。そして、図１０の断面図に示すように、キー部材３０の凸部３０１は締結本体２０の第一溝状部２０１に嵌合する。これが、図１０に示す仮挿着の状態である。仮挿着の状態では、キー部材３０の突起部３３８は、その底辺が窓孔口２２２よりも外側に突出しているため、更に負荷してキー部材３０を軸芯方向へ押し込んだとしても、突起部３３８が窓孔口２２２にぶつかるので、それ以上キー部材３０が下方へ移動することはない。
【００５９】
なお、上記仮挿着の状態で、ワイヤケーブルの両端部に引っ張り荷重を加えるプリテンションを行う。プリテンションを行う際は、ワイヤケーブル４２の一端では突起部４４にプリテンション用引っ掛け治具（図示せず）をワイヤケーブル４２側から引っ掛け、ワイヤケーブル４２の他端を固定し、引っ張り荷重を加える。プリテンションを各部品の組み付け後に行うことで、ワイヤケーブル４２の性能を安定化すると共に、各部品の結合強度を確認できる。
【００６０】
その後、コントロールケーブルをトランスミッションに使用する場合は、仮挿着の状態にある締結部材の係止部２９をシフトレバー側に、他端をトランスミッション側に固定する。
【００６１】
次に、ケーブル４０の係止端部４１を挿着孔２１内で軸方向に摺動させ、ケーブル４０の長さを調整する。この際、係止端部４１の摺動距離は、空間部２７で規制される。ケーブル４０が適度な長さとなったら、キー部材３０の上方から両端を押さえることにより操作部３１８を空間部３１７の方へ撓ませ、突起部３３８を窓孔口２２２よりも内側へ移動させる。そして、そのままの状態でキー部材３０を軸芯方向へ挿入し、キー部材３０の凸部３０１を締結本体２０の第二溝状部２０２に嵌合させると同時に、突起部３３８を係合溝２２８に係合させる。こうして、キー部材３０の雌螺子３１１とケーブル４０の雄螺子４１１とが係止する。雌螺子３１１と雄螺子４１１とが係止することにより、ケーブル４０が所望の長さを保って本発明の締結部材に固定される。これが、図１１に示す本挿着の状態である。
【００６２】
この際、キー部材３０の４つの突出部３１３は、締結本体２０の凹部２２３に嵌りこむ。これにより、キー部材３０が窓孔２２内でがたつくのを抑制できる。さらに、キー部材３０の突起部３３８は、締結本体２０の係合溝２２８と係合し、操作部３１８を作動させない限り係合は解けないので、キー部材３０の抜け出しを防止することができる。また、本挿着後の締結本体２０とキー部材３０は、天井部３１や脚部３６の端面が締結本体２０の側面と同一円周上にあり、突出した部分がなく、締結部材全体として円筒状となる。
【００６３】
本挿着から、再び仮挿着の状態に戻すには、窓孔口２２２の面取りされた部分からキー部材３０の両側面を押さえて操作部３１８を隙間３１７の方へ撓ませる。キー部材３０の側面が隙間３１７の方へ撓むことにより、突起部３３８と係合溝２２８との係合が解けるので、キー部材３０を締結本体２０から抜き出すと、仮挿着の状態となる。
【００６４】

【００６６】
本実施例のコントロールケーブルの締結部材において、締結本体５０は、窓孔を除いて、実施例１（締結本体２０）と同一形状である。なお、締結本体５０では、円筒部材５８、係止部５９、空間部５７、挿着孔５１とする。
【００６７】
締結本体５０の窓孔５２は、挿着孔５１とその奥側で交差し、円筒部材５８を貫通する。窓孔５２は、後述するキー部材６０を着脱可能に挿着する孔である。窓孔５２は、円筒部材５８の軸方向に平行かつ互いに平行に対向する２つの面５５１と、面５５１に垂直かつ互いに平行に対向する２つの面５５６を有する。
【００６８】
２つの面５５１は、それぞれ、互いに平行な第一溝状部５０１と第二溝状部５０２とを有する。第一溝状部５０１と第二溝状部５０２は、円筒部材５８の軸方向と平行となっている。なお、キー部材６０は４つの面５５１，５５６で形成された窓孔５２の長方形の窓孔口５５２から挿入されるが、窓孔口５５２に近い方が第一溝状部５０１である。また、向かい合う２つの第一溝状部５０１と、向かい合う２つの第二溝状部５０２は、窓孔口５５２から互いに同じ距離にある。そして、第一溝状部５０１は半円、第二溝状部５０２は４分の１円の円周部分を内周面とし、その半円と４分の１円は同一半径である。
【００６９】
さらに２つの面５５１は、それぞれ、両端部に断面長方形状の係合溝５５８を有する。窓孔口５５２の面５５１側には、段差部５５３が設けられているが、段差部５５３の底面と距離を隔てて係合溝５５８が形成される。係合溝５５８は、溝状部５０１，５０２とは垂直方向である。
【００７０】
上記の第一溝状部５０１と第二溝状部５０２、係合溝５５８は、それぞれキー部材６０の一部と係合する。
【００７１】
［キー部材］
図１５は、本発明のコントロールケーブルの締結部材のキー部材の斜視図である。また、図１６は本発明のコントロールケーブルの締結部材の締結本体の平面図であって、図１６のＹ−Ｙ断面図を図１７に、Ｚ−Ｚ断面図を図１８に示す。
【００７２】
本実施例のコントロールケーブルの締結部材において、キー部材６０は、ガラス繊維強化ナイロン樹脂製である。キー部材６０は、全体としてＵ字形状であり、締結本体５０の円筒部材５８の外周面と同一の曲率半径の外面をもった天井部６１と、天井部６１から直線的に延出する２つの脚部６６とからなる。そして、脚部６６の端面は、天井部６１の外面と同一円周上にある。また、Ｕ字形状のキー部材６０の内周面、すなわち、天井部６１と２つの脚部６６とで形成される空間の内周面には、雌螺子６１１が形成されている。
【００７３】
キー部材６０の外面をなす２つの脚部６６の側面は、それぞれ外側に突出した断面半円状の凸部６０１を有する。この凸部６０１は、締結本体５０の第一溝状部５０１および第二溝状部５０２と嵌合する。すなわち、第一溝状部５０１と第二溝状部５０２、凸部６０１で主ロック部が構成される。凸部６０１は、脚部６６の側面に一体的に形成された薄片状の弾性片６６１の先端に位置する。弾性片６６１は薄片状で、かつ、脚部６６と弾性片６６１との間には隙間６６７が設けてあるので、弾性片６６１の先端に位置する凸部６０１に力が加わると弾性片６６１が隙間６６７側へ撓む。
【００７４】
また、弾性片６６１および凸部６０１が形成された両側には、操作部６１８を有する。操作部６１８は板状で、脚部６６と一体的に形成されており、脚部６６と操作部６１８との間には隙間６１７が設けてある。操作部６１８の先端部には、突出部６３８を有する。突出部６３８は、天井部６１の外面と曲率の等しい扇形断面をもつ。また、操作部は外側に突出した断面方形状の突起部６６８をもつ。
【００７５】
操作部６１８は、隙間６１７の方へ力を加えると撓みを生じるので、操作部６１８を動かすことにより突起部６６８が移動する。なお、突出部６３８に固定された操作棒６４８は、同一面に設けられた操作部３１８を同時に操作するための取っ手である。突起部６６８は、締結本体５０の係合溝５５８と係合する。すなわち、操作部６１８、突起部６６８および係合溝５５８で副ロック部が構成される。
【００７６】
［締結操作］
図１９および図２０を用いて、本実施例のコントロールケーブルの締結部材の締結操作を説明する。なお、ケーブル４０は、係止端部４１の外周面に円周状に形成された段差部４５を有する他は、実施例１と同様である（図２２参照）。
【００７７】
キー部材６０は、締結本体５０の窓孔口５５２より軸芯方向へ挿入される。この際、キー部材６０の凸部６０１は窓孔５２の面５５１よりも外側へ突出しているので、凸部６０１は面５５１に相対的に押されることにより弾性片６６１が隙間６６７の方へ撓む。そして、図１９の断面図に示すように、キー部材６０の凸部６０１は締結本体５０の第一溝状部５０１に嵌合する。これが、図１９に示す仮挿着の状態である。仮挿着の状態では、キー部材６０の突起部６６８は、その底辺が窓孔口５５２よりも外側に突出しているため、更に負荷してキー部材６０を軸芯方向へ押し込んだとしても、突起部６６８が窓孔口５５２にぶつかるので、それ以上キー部材６０が下方へ移動することはない。
【００７８】
なお、上記仮挿着の状態で、ワイヤケーブル４２の両端部に引っ張り荷重を加えるプリテンションを行う。プリテンションを行う際は、ワイヤケーブル４２の一端では段差部４５にプリテンション用引っ掛け治具（図示せず）をワイヤケーブル４２側から引っ掛け、ワイヤケーブル４２の他端を固定し、引っ張り荷重を加える。
【００７９】
ケーブル４０を適度な長さに調節したら、キー部材６０の操作棒６４８を押さえることにより操作部６１８を隙間６１７の方へ撓ませ、突起部６６８を窓孔口５５２よりも内側へ移動させる。そして、そのままの状態でキー部材６０を軸芯方向へ挿入し、キー部材６０の凸部６０１を締結本体５０の第二溝状部５０２に嵌合させると同時に、突起部６６８を係合溝５５８に係合させる。こうして、キー部材６０の雌螺子６１１とケーブル４０の雄螺子４１１とが係止する。雌螺子６１１と雄螺子４１１とが係止することにより、ケーブル４０が所望の長さを保って本発明の締結部材に固定される。これが、図２０および図２１に示す本挿着の状態である。
【００８０】
この際、キー部材６０の突起部６６８は、締結本体５０の係合溝５５８と係合し、操作部６１８を作動させない限り係合は解けないため、キー部材６０の抜け出しを防止することができる。また、本挿着後の締結本体５０とキー部材６０は、天井部６１や脚部６６の端面、突出部６３８が締結本体５０の側面と同一円周上にあり、突出した部分がなく、締結部材全体として円筒状となる。
【００８１】
本挿着から、再び仮挿着の状態に戻すには、窓孔口５５２の段差部５５３からキー部材６０の操作棒６４８を押さえて操作部６１８を隙間６１７の方へ撓ませる。操作部６１８が隙間６１７の方へ撓むことにより、突起部６６８と係合溝５５８との係合が解けるので、キー部材６０を締結本体５０から抜き出すと、仮挿着の状態となる。
【００８２】
【発明の効果】
本発明のコントロールケーブルの締結部材は、外周に第一係止歯をもつ棒状の係止端部を有するコントロールケーブルの該係止端部が挿着される挿着孔と、該挿着孔の奥側で該挿着孔と交差する窓孔と、を有する締結本体と、前記窓孔に着脱自在で、かつ前記第一係止歯と挿着時に係止する第二係止歯を有するキー部材と、を有するコントロールケーブルの締結部材であって、前記締結本体および前記キー部材は、該キー部材の挿着および脱着により該締結本体と該キー部材とを係合および開合する主ロック部と、前記キー部材に設けられた操作部により前記締結本体と前記キー部材との固定と解除を行う副ロック部とを有することを特徴とする。
【００８３】
上記構成によれば、操作部を動かさない限り副ロック部の固定・解除ができないので、別部材を用いることなく誤操作による締結本体とキー部材との着脱を防止できる。そのため、キー部材が締結本体に挿着または脱着した状態を保持するための別の部品や、その部品の固定や解除が不要となる。
【００８４】
特に、前記主ロック部は、互いに嵌合する前記締結本体に設けられた断面扇形状の凹部と、前記キー部材に設けられた断面扇形状の凸部からなり、また、断面扇形状の前記凹部は、前記締結本体に前記キー部材を仮挿着する第一溝状部と本挿着する第二溝状部とから成り、両者は互いに平行であるのが好ましい。第一溝状部と第二溝状部とが互いに平行であると、同一方向への二段階の動きにより、キー部材を締結本体に仮挿着した状態や本挿着した状態に着脱することができる。そのため、仮挿着の状態を保持するための別の部品や、その部品の固定や解除が不要となる。

BEST MODE FOR CARRYING OUT THE INVENTION
The fastening member of the control cable of the present invention has a fastening body and a key member.
[0019]
The fastening body has an insertion hole into which the locking end of the control cable is inserted, and a window hole that intersects the insertion hole at the back of the insertion hole.
[0020]
The control cable (hereinafter referred to as "cable") inserted into the fastening body is not particularly limited as long as it is a cable generally used as an inner cable of the control cable, but has a first locking tooth on the outer periphery. It has a bar-shaped locking end.
[0021]
The material for the locking end may be appropriately selected in consideration of the mechanical strength and the like desired for the fastening member. The shape and size of the locking end may be appropriately selected according to the size of the fastening member.
[0022]
The locking end has first locking teeth on its outer periphery. The first locking teeth only need to have a shape capable of restricting at least the movement of the cable in the axial direction when locked with the second locking teeth (described later) of the key member. Therefore, the locking end portion may be formed with first protrusions and recesses extending in the axial direction around the outer peripheral surface in a ring shape. Specific examples include male screws and bellows-like irregularities formed at equal intervals in the axial direction.
[0023]
Further, a guide portion larger than the outer diameter of the first locking tooth may be formed at the end of the locking end portion. By forming the guide portion, when the locking end is inserted into the insertion hole of the fastening body, the first locking tooth is prevented from contacting the insertion hole, so that the locking end is inserted. It can be smoothly inserted into the hole, and can be easily inserted to an appropriate position. Further, a projection for preventing the locking end from falling out of the insertion hole of the fastening body may be formed at the tip of the locking end.
[0024]
Further, it is preferable that the other end of the locking end has a step portion used in the step of pretensioning the cable. The pretensioning step is a step of applying a tensile load to both ends of the cable to remove the initial elongation of the cable.
[0025]
The material of the fastening body may be appropriately selected in consideration of the mechanical strength and the like desired for the fastening member, but is preferably made of a resin such as polyacetal, nylon, or polypropylene. Although the shape of the fastening body is not particularly limited, it is preferable that the whole is cylindrical. In addition, it is desirable that the fastening body has, at one end, a locking portion that can lock another member such as a pin, a bolt, and a rivet.
[0026]
The fastening body has an insertion hole into which the locking end of the cable is inserted. The shape and size of the insertion hole are not particularly limited as long as the locking end can be inserted, and may be appropriately selected according to the shape and size of the locking end. In addition, the fastening body has a window hole that intersects with the insertion hole on the back side of the insertion hole. The deep side of the insertion hole refers to an end of the insertion hole, that is, a portion other than a portion serving as a cable entrance / exit. The shape and size of the window hole are not particularly limited as long as the window hole is located at a position intersecting the insertion hole on the back side of the insertion hole.
[0027]
The key member is detachable from the window hole of the fastening body and has second locking teeth that lock with the first locking teeth of the cable when inserted.
[0028]
The material of the key member may be appropriately selected in consideration of the mechanical strength and the like desired as a fastening member, but is preferably made of a resin such as polyacetal, nylon, or polypropylene. The size of the key member is not particularly limited as long as it can be inserted into the window hole of the fastening body. Further, the key member is preferably U-shaped, and preferably has second locking teeth on the inner peripheral surface of the U-shape.
[0029]
The second locking tooth only needs to have a shape that can restrict at least movement of the cable in the axial direction when locked with the first locking tooth formed at the locking end of the cable. For example, if the first locking tooth is a male screw, the second locking tooth is a female screw to be screwed with the male screw.If the first locking tooth is a bellows-like unevenness, the second locking tooth is a second locking tooth. By using the unevenness fitting with the unevenness, the movement of the cable in the axial direction can be restricted. Further, if a combination of a plurality of projections and locking teeth in which the projections are locked with the recesses, the rotation can be restricted together with the movement of the cable in the axial direction.
[0030]
In the fastening member of the control cable of the present invention, the fastening body and the key member have a main lock portion that engages and opens the fastening body and the key member by inserting and removing the key member.
[0031]
The main lock portion is not particularly limited as long as the main body and the key member can be detachably engaged and opened with each other, but is provided on the main body and the key member, and is one of a concave portion and a convex portion that are fitted to each other. And each having the other. The concave portion and the convex portion may be provided on either the fastening body or the key member as long as they are fitted to each other, and the number is not limited.
[0032]
Preferably, at least one of the concave portion and the convex portion is provided on the elastic member. The elastic member is bent by a force applied when the key member is inserted into or detached from the fastening body. When the elastic member bends, the concave portion and the convex portion can be smoothly moved and fitted. Further, by adjusting the degree of bending, the operation amount of the key member and the load at the time of operation can be set to desired values. When it is desired to reduce the load at the time of operation, the thickness of the elastic member may be reduced to facilitate the bending, or the elastic member may be appropriately adjusted by selecting the elastic member which is likely to be bent.
[0033]
The concave and convex portions are preferably fan-shaped in cross section. The effect of the case where the shape of the concave and convex portions is a sector shape in cross section will be described in comparison with the case where the shape is a different shape. FIG. 1 shows the shapes of the member having the concave portion and the member having the convex portion, and the P-δ characteristics when the member having the convex portion is loaded in the direction of the arrow. FIG. 1 (I) uses a member having a concave portion and a convex portion having a semicircular shape and (II) a wedge-shaped cross section. From the state where the convex portion is fitted to the member having the concave portion whose position is fixed, a load is applied to the member having the convex portion in the direction of the arrow in the figure to cause the member having the convex portion to bend, thereby causing the convex portion to be bent. Move in the direction of. Further, in the graph showing the P-δ characteristic, P is the applied load, δ is the moving distance, P _I , P _II Is the working load.
[0034]
In (I) corresponding to the configuration of the present invention, the applied load is P _I , The slope of the graph of the P-δ characteristic is steeper than that of (II), and the member having the convex portion under the operating load or less has a small deflection and a small moving distance. Therefore, the detachment strength between the concave portion and the convex portion also increases. Therefore, the configuration in which the concave portion and the convex portion have a fan-shaped cross section is effective in preventing attachment / detachment due to an erroneous operation that may occur during conveyance or the like. In addition, contrary to the above, the same applies when a member having a convex portion is loaded in a direction opposite to the arrow in FIG.
[0035]
The concave and convex portions having a fan-shaped cross section are not particularly limited as long as they fit into each other, and a combination of a convex portion having a semicircular cross section and a concave portion having a groove shape, or a convex portion having a semispherical shape and a hemispherical portion. Any combination such as a combination with a concave portion having a convex surface may be used.
[0036]
In addition, the concave and convex portions having a fan-shaped cross section that are detachably fitted may have a plurality of concave portions (or convex portions) for one convex portion (or concave portion). More preferably, one convex portion has two concave portions. With a configuration having two concave portions for one convex portion, two-stage fitting is possible.
[0037]
The fastening member of the control cable according to the present invention has a sub-lock portion that fixes and releases the fastening body and the key member by an operation unit provided on the key member.

The protrusions and the engagement portions may be provided on either the fastening body or the key member as long as they are fitted to each other, and the number is not limited. It is assumed that the projection and the engaging portion cannot be fixed / released without using the operation portion when fixing and releasing the fixing body and the key member. Therefore, it is desirable that the projections and the engagement portions have a rectangular cross section.
[0039]
The operation unit is provided in the key member, and is not limited in its form, as long as the operation unit can be operated to fix and release the fastening body and the key member, but is in the form of a flexible plate. It is desirable. By bending the operating portion by applying a force, the protrusion of the auxiliary lock portion and the engaging portion can be engaged or released. Further, in order to easily apply a force to the operation unit, a handle may be provided on the operation unit, or a dedicated device that allows the key member to be attached and detached while the force is applied to the operation unit may be used.
