Description

【０００１】
【発明の属する技術分野】
この発明は、雌部材内に雄部材の一部を差し入れることにより、当該雌部材と雄部材とを掛合解除操作可能に掛合させ、この掛合により雌部材側に取り付けられるなどした部材と雄部材側に取り付けられるなどした部材とを留め合わせるバックルであって、特に、バックルの使用上前面となる側から前記掛合解除操作が可能とされる、いわゆるフロントリリースタイプのバックルの改良に関する。
【０００２】
【従来の技術】
バックルの使用上前面となる側から、バックルを構成する雄部材と雌部材との掛合を解除操作可能とする、いわゆるフロントリリースタイプのバックルにあっては、従来、図２５および図２６に示される構造が用いられていた。
【０００３】
すなわち、かかる従来のバックルにあっては、扁平筒状をなす雌部材２００における前面側に操作窓２０１を開設させると共に、雄部材１００における雌部材２００内への差し込み部１０１に当該雌部材２００内への差し入れに伴って弾性変形され、かつ、所定の差入位置で弾性復帰して前記操作窓２０１の差し入れ手前側１０４の窓縁２０２に先端側１０３を掛合させる弾性片１０２を備えさせる構造とされており、前記所定の差入位置において前記操作窓２０１を通じて当該操作窓２０１の窓縁２０２に掛合された弾性片１０２が外方から臨まれるようにしてある。そして、この掛合状態において前記操作窓２０１に臨んだ弾性片１０２を押圧操作することにより、当該弾性片１０２と操作窓２０２との掛合を解除し、前記雌部材２００内から前記雄部材１００の差し込み部１０１を抜き出すことができるようにしてある。
【０００４】
【発明が解決しようとする課題】
しかるに、かかる従来のバックルにあっては、前記弾性片１０２と操作窓２０１との掛合の解除、すなわち、掛合状態にある雄部材１００と雌部材２００との掛合の解除を、かかる掛合状態において前記操作窓２０１に臨む弾性片１０２を当該操作窓２０１に指先を差し入れるなどして押圧操作してなすものであるが、この押圧操作のみによっては前記弾性片１０２と前記操作窓２０１との掛合が解かれるに過ぎず押圧操作を止めれば再び弾性片１０２が弾性復帰して前記操作窓２０１に掛合されてしまうため、雄部材１００と雌部材２００とを分離するためには、前記押圧操作をしながら雄部材１００の差し込み部１０１が雌部材２００内から抜き出す向きに移動されるように雄部材１００を操作せざるを得ず、かかる分離操作は必ずしも容易なものではなかった。
【０００５】
特に、かかる分離操作を片手で行おうとすると、前記雄部材１００の弾性片１０２を押圧操作しながら当該弾性片１００を押圧する指を当該雄部材１００の差し入れ手前側１０４に移動させて雄部材１００をスライドさせるようにする必要があるところ、こうしたスライド操作にあたり指が前記雌部材２００の操作窓２０１における雄部材１００の差し込み部１０１の差し入れ手前側１０４の窓縁２０２と前記弾性片１０２との間に挟まれるようになって当該スライド操作を円滑になし得ない場合も少なくなかった。
【０００６】
そこでこの発明は、第一に、かかる従来のフロントリリースタイプのバックルの不都合を解消することを目的とする。また、第二に、片手をもって雄部材と雌部材との掛合の解除・分離を円滑になし得るようにすることを目的とする。
【０００７】
【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、バックルが以下の（１）〜（６）の構成を備えたものとした。
（１）一端側に差し入れ開口を備えた筒状をなす雌部材と、この差し入れ開口から当該雌部材内に差し入れられる差し込み部を備える雄部材とを有するバックルであって、
（２）前記雌部材が、前板部と後板部とを有すると共に、前記雄部材が、前記差し込み部に、前記雌部材への差し込みに伴って当該雌部材の前板部の内面に弾性変形された状態で先端側を接しさせる弾性片を備えており、
（３）前記雌部材の前板部の内側部には、前記雄部材の差し込み部の所定の差し込み位置で前記弾性片を弾性復帰させて当該弾性片の先端部に掛合する段差状の掛合部が設けてあると共に、
（４）当該雌部材の前板部には、当該雌部材内に弾性的に押し込み操作可能な操作片が割溝を介して区分して設けてあり、この操作片が前記押し込み操作により前記掛合部に掛合された雄部材の弾性片における前記雌部材の前板部側に向けられた当接面に押し当てられて当該弾性片を前記掛合部との掛合を解く向きに弾性変形させる構成としてあり、
（５）しかも、前記雄部材における差し込み部の弾性片の当接面が、前記雌部材への当該差し込み部の差し入れ先側から差し入れ手前側に向けて、次第に当該雌部材の前記前板部側に近付く向きの傾斜を備えており、この傾斜により前記雌部材の操作片を前記弾性片に押し当てられた雄部材が前記差し入れ開口から抜け出す向きに移動される構成としてあり、
（６）しかも、雌部材における掛合部と差し入れ開口との間にわたる当該雌部材の前板部の内側部が、当該雌部材の内奥側から差し入れ開口側に向けて次第に後板部の側から離れる向きに傾斜する案内面としてあると共に、この案内面に沿って、前記雌部材の操作片の押し込み操作に伴って前記掛合部と弾性片との掛合を解かれて前記差し入れ開口側に移動される雄部材の当該弾性片の先端部が、当該弾性片を弾性復帰させながら前記差し入れ開口側に案内され、この案内に伴って前記雄部材が前記雌部材内からの抜き出し方向に移動される構成としてある。
【０００８】
かかる構成によれば、前記雄部材の差し込み部を雌部材内に差し入れ掛合させることにより、この雄部材に取り付けられ、あるいは、この雄部材が取り付けられている部材と、かかる雌部材に取り付けられ、あるいは、この雌部材が取り付けられている部材とを、かかるバックルを介して留め合わせることができる。
【０００９】
また、かかる掛合状態から前記雌部材の前板部に設けられた操作片を押し込み操作することにより、前記弾性片の先端部と前記掛合部との掛合を解いて、雄部材の差し込み部を雌部材内から抜け出し可能として、雄部材と雌部材とを分離させることができ、これにより、かかるバックルを介して留め合わされた二つの部材の当該留め合わせをワンタッチで解くことができる。
【００１０】
この結果、この実施の形態にかかるバックルは、主として、前記雌部材の前板部側を正面側として適宜の部材に当該雌部材を取り付けると共に、留め付けの相手方となる他の部材に雄部材を取り付けて用いるのに適している。
【００１１】
また、前記雄部材における差し込み部の弾性片の当接面が、前記雌部材への当該差し込み部の差し入れ先側から差し入れ手前側に向けて、次第に当該雌部材の前記前板部側に近付く向きの傾斜を備えており、この傾斜により前記雌部材の操作片を前記弾性片に押し当てられた雄部材が前記差し入れ開口から抜け出す向きに移動される構成を備えていることから、前記掛合状態から前記雌部材の操作片を押し込み操作することにより、前記弾性片の先端部と前記掛合部との掛合を解くと共に、このように掛合の解かれた雄部材を雌部材の差し入れ開口から抜け出される向きに移動させることができる。これにより、前記雌部材の操作片の押し込み操作を止めても、雄部材の弾性片が雌部材の掛合部に再び掛合されないようにでき、その後の雄部材の差し込み部の雌部材内からの抜き出しをスムースになすことができる。
【００１３】
また、かかる構成によれば、前記雌部材の操作片の押し込み操作に伴って前記掛合部と弾性片との掛合を解き、雄部材の弾性片が雌部材の掛合部に再び掛合しないように当該雄部材を前記差し入れ開口側に移動させることができると共に、このように移動された雄部材をさらに、前記案内面への前記弾性片の先端部の案内によって、格別の引き抜き操作をなすことなく、雌部材内から抜き出させることができ、雄部材と雌部材との分離を一層スムースになすことができる。
【００１４】
【発明の実施の形態】
以下、図１ないし図２４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。
【００１５】
なお、ここで図１ないし図６は、この実施の形態にかかるバックルを構成する雄部材２と雌部材１とを掛合し合わせた状態を示しており、図１を平面図とした場合、図３は正面図、図４左側面図、図５は右側面図、図６は底面図であり、また、図２は雄部材２の雌部材１内への差し入れ方向Ｓに沿って縦断面にした状態として示している。

【００１８】
さらに、図１９ないし図２４は、前記雄部材２と雌部材１との係脱過程を理解し易いように、当該雄部材２と雌部材１をそれぞれ縦断面にしてそれぞれ示したものであり、図１９は雌部材１内に雄部材２の差し込み部２０を差し入れる直前の状態を、図２０は雌部材１の案内面１７ａに弾性片２１の先端部２１ａを押し当てて当該弾性片２１を弾性変形させながら雌部材１内にかかる差し込み部２０を差し入れ始めた状態を、図２１は雄部材２における弾性片２１の先端部２１ａを当該弾性片２１の弾性復帰により雌部材１の掛合部１５に掛合させた状態を、図２２は図２１の状態から雌部材１の操作片１６を内側に押し込み操作して雄部材２の弾性片２１を弾性変形させた状態を、図２３は雌部材１の操作片１６の押し込み操作に伴って雄部材２が弾性片２１における当接面２１ｃの傾斜により雌部材１内から抜け出す向きにやや移動された状態を、図２４は雌部材１の案内面１７ａに弾性片２１の先端部２１ａを再び突き当てさせる位置まで移動され、かつ、この案内面１７ａの傾斜により雌部材１内から抜け出す向きにさらに雄部材２が移動されている状態を、それぞれ示している。
【００１９】
この実施の形態にかかるバックルは、一端側に差し入れ開口１０を備えた偏平筒状をなす雌部材１と、この雌部材１の差し入れ開口１０から当該雌部材１内に差し入れられる差し込み部２０を備える雄部材２とからなる。かかる雄部材２は、前記雌部材１内への所定の差し込み位置Ｒへの差し入れにより、当該雌部材１内から前記差し込み部２０を抜け出さないように当該雌部材１の前板部１２の内側部に設けられた掛合部１５に先端部２１ａを掛合させる弾性片２１を前記差し込み部２０に備えている。（以下、かかる弾性片２１の先端部２１ａを前記掛合部１５に掛合させた状態を、バックルの掛合状態Ｋという。）また、前記雌部材１の前板部１２には、当該雌部材１内に押し込み操作可能な操作片１６が設けてあり、この操作片１６は前記押し込み操作により、前記掛合状態Ｋにおける弾性片２１の前記前板部１２側に向けられた当接面２１ｃに押し当てられて当該弾性片２１を前記掛合部１５との掛合を解く向きに弾性変形させるように構成してある。
【００２０】
したがって、この実施の形態にかかるバックルによれば、前記雄部材２の差し込み部２０を雌部材１内に差し入れることによる前記掛合状態Ｋにより、この雄部材２に取り付けられ、あるいは、この雄部材２が取り付けられている部材と、かかる雌部材１に取り付けられ、あるいは、この雌部材１が取り付けられている部材とを、かかるバックルを介して留め合わせることができる。また、かかる掛合状態Ｋから前記雌部材１の前板部１２に設けられた操作片１６を押し込み操作することにより、前記弾性片２１の先端部２１ａと前記掛合部１５との掛合を解いて、雄部材２の差し込み部２０を雌部材１内から抜け出し可能として、雄部材２と雌部材１とを分離させることができ、これにより、かかるバックルを介して留め合わされた二つの部材の当該留め合わせをワンタッチで解くことができる。
【００２１】
この結果、この実施の形態にかかるバックルは、主として、前記雌部材１の前板部１２側を正面側として適宜の部材に当該雌部材１を取り付けると共に、留め付けの相手方となる他の部材に雄部材２を取り付けて用いるのに適しており、例えば、スキーウェアなどの肩ベルトの端部と胸当てとの留め合わせをなすように当該スキーウェアなどの外側に前記雌部材１の前板部１２が向けられるようにして当該肩ベルトの端部と胸当てとの留め合わせ箇所にそれぞれ前記雌部材１と前記雄部材２とを取り付けるように用い、また、ウエストバックの腰巻きベルトの両端部の留め合わせをなすように当該腰巻きベルトにおける巻回外側に前記雌部材１の前板部１２が向けられるようにして当該腰巻きベルトの両端部にそれぞれ前記雌部材１と前記雄部材２とを取り付けるように用い、また、かばんの蓋と本体との留め合わせをなすように当該かばんにおける外側に前記雌部材１の前板部１２が向けられるようにして当該蓋と本体との留め合わせ箇所にそれぞれ前記雌部材１と前記雄部材２とを取り付けるように用い、また、スーツケースの内側において留め合わせ張り込まれる一対のベルトの当該留め合わせをなすように当該スーツケースの蓋と本体とが向き合った側に前記雌部材１の前板部１２が向けられるようにして当該一対のベルトの留め合わせ箇所にそれぞれ前記雌部材１と前記雄部材２とを取り付けるように用いられる。
【００２２】
また、この実施の形態にかかるバックルは、前記雄部材２における差し込み部２０の弾性片２１の当接面２１ｃが、前記雌部材１への当該差し込み部２０の差し入れ先側から差し入れ手前側に向けて、次第に当該雌部材１の前記前板部１２側に近付く向きの傾斜を備えており、この傾斜により前記雌部材１の操作片１６を前記弾性片２１に突き当てられた雄部材２が前記差し入れ開口１０から抜け出す向きに移動される構成を備えている。
【００２３】
この結果、この実施の形態にかかるバックルにあっては、前記掛合状態Ｋから前記雌部材１の操作片１６を押し込み操作することにより、前記弾性片２１の先端部２１ａと前記掛合部１５との掛合を解くと共に、このように掛合の解かれた雄部材２を雌部材１の差し入れ開口１０から抜け出される向きに移動させることができる。これにより、前記雌部材１の操作片１６の押し込み操作を止めても、雄部材２の弾性片２１が雌部材１の掛合部１５に再び掛合されないようにでき、その後の雄部材２の差し込み部２０の雌部材１内からの抜き出しをスムースになすことができる。
【００２４】
また、この実施の形態にかかるバックルにあっては、雌部材１における掛合部１５と差し入れ開口１０との間にある当該雌部材１の前板部１２の内側部に、当該雌部材１の内奥側から差し入れ開口１０側に向けて次第に後板部の側から離れる向きに傾斜する案内面１７ａが設けてあると共に、この案内面１７ａに沿って、前記雌部材１の操作片１６の押し込み操作に伴って前記掛合部１５と弾性片２１との掛合を解かれて前記差し入れ開口１０側に移動される雄部材２の当該弾性片２１の先端部２１ａが、当該弾性片２１を弾性復帰させながら前記差し入れ開口１０側に案内され、この案内に伴って前記雄部材２が前記雌部材１内からの抜き出し方向に移動される構成としてある。
【００２５】
この結果、この実施の形態にかかるバックルにあっては、前記雌部材１の操作片１６の押し込み操作に伴って前記掛合部１５と弾性片２１との掛合を解き、雄部材２の弾性片２１が雌部材１の掛合部１５に再び掛合しないように当該雄部材２を前記差し入れ開口１０側に移動させることができると共に、このように移動された雄部材２をさらに、前記案内面１７ａへの前記弾性片２１の先端部２１ａの案内によって、格別の引き抜き操作をなすことなく、雌部材１内から抜き出させることができる。
【００２６】
より詳細には、先ず、この実施の形態にかかる雌部材１は、幅広の前記前板部１２と後板部１３とを、前記雄部材２の差し込み部２０を差し入れ可能な間隔を開けて備えると共に、この前板部１２と後板部１３とにおける前記差し込み部２０の差し入れ方向Ｓに沿った両側縁部間にそれぞれ、この側縁部間に亙る幅狭の側板部１４を備えた偏平筒状に構成してある。
【００２７】
このように構成される雌部材１は、一端側に細長い前記雄部材２の差し込み部２０の差し入れ開口１０を備えると共に他端側においても開口１１されている。
【００２８】
かかる雌部材１の前記前板部１２は、その内側部における前記差し入れ開口１０側に、この差し入れ開口１０側から当該雌部材１の内奥側に向けて次第に前記後板部１３内面に近付く向きに、言い換えれば、当該雌部材１の内奥側から差し入れ開口１０側に向けて当該後板部１３内面から離れる向きに傾斜する案内面１７ａと、この案内面１７ａにおける雌部材１の内奥側に頂端１７ｂ縁を介して連続すると共に、前記雄部材２の差し込み部２０の差し入れ方向Ｓに略直交する向きに形成された段差面１７ｃとを備えた突き出し部１７を有している。この実施の形態にあっては、かかる段差面１７ｃが前記雄部材２の差し込み部２０における弾性片２１の先端部２１ａが掛合される掛合部１５とされる。したがって、この突き出し部１７における前記段差面１７ｃは、前記雌部材１における前記差し入れ開口１０と反対の開口１１側に向けられている。また、この突き出し部１７は、雌部材１の前記前板部１２の幅方向（前記雄部材２の差し込み部２０の差し入れ方向Ｓに直交する向き）に向けて長く設けてある。なお、この実施の形態にあっては、前記案内面１７ａは、前記雄部材２の弾性片２１の幅寸法よりもやや広い幅で設けてあり、この案内面１７ａを挟んだ両側には、差し入れられる雄部材２の弾性片２１の両側部をガイドする段面１２ａが形成されている。
【００２９】
また、かかる雌部材１の前記前板部１２は、この前板部１２に設けられた割溝１６ａにより区分され、雌部材１の内側に向けて先端側を弾性的に押し込み操作可能な操作片１６を有している。
【００３０】
この実施の形態にあっては、前記前板部１２に、前記雄部材２の差し込み部２０における差し入れ方向Ｓに沿った二条の縦側割溝１６ａ’、１６ａ’が当該前板部１２内外を貫通するように、前記雄部材２の弾性片２１の幅寸法と略等しい間隔を開けて設けてあると共に、この二条の縦側割溝１６ａ’、１６ａ’における前記差し入れ開口１０側にある溝端間に亙って当該二条の縦側割溝１６ａ’、１６ａ’に連通する横側割溝１６ｂ”が、前記掛合状態Ｋにおいて前記突き出し部１７における前記段差面１７ｃとの間に前記雄部材２の差し込み部２０における弾性片２１の先端部２１ａが突き当たる平坦面１２ｂを残すように、前記前板部１２内外を貫通させた状態で設けてある。この結果、この実施の形態にあっては、前記操作片１６は前記横側割溝１６ｂ”による区分側を先端側として雌部材１内に弾性的に押し込み操作可能とされる。
【００３１】
なお、この実施の形態にあっては、前記横側割溝１６ｂ”が、その中央側を前記差し入れ開口１０側に突き出すように、湾曲状に形成してある。また、前記操作片１６は、その先端側を基部側に対して厚肉とするように構成してあり、この操作片１６の外側におけるかかる先端側と基部側との間には傾斜状の段差面１６ｂが形成されている。
【００３２】
また、前記前板部１２は、前記突き出し部１７の段差面１７ｃから前記差し入れ開口１０と反対側の開口１１縁に亙る間において、その内面を、前記平坦面１２ｂと略同面とするように構成してある。
【００３３】
また、この実施の形態にあっては、前記後板部１３における前記開口１１側には、当該開口１１縁との間に間隔を開けて、当該後板部１３の幅方向に亙る長穴状をなすバンドなどの帯状体Ｈの差し入れ穴１３ａが貫通状態に設けてあり、この差し入れ穴１３ａと前記開口１１縁との間を帯状体Ｈの巻き掛け部１３ｂとして、かかる雌部材１を当該帯状体Ｈの端部などに取り付けることができるようにしてある。
【００３４】
また、この実施の形態にあっては、一対の前記側板部１４、１４は、雄部材２の差し込み部２０の差し入れ方向Ｓに沿った両側端面２０ａを当該側板部１４内面によりガイドする間隔を開けて設けてある。また、この側板部１４は、前記差し入れ開口１０側において、前記前板部１２および後板部１３の幅方向に亙る側縁との間に間隔を開けるように設けてあり、雌部材１は、この差し入れ開口１０側において、その幅狭側に側方開放部１４ａを有している。なお、図中符号１４ｂで示すのは、前記差し入れ開口１０側から前記開口１１側に向けて幅を次第に狭くするように雌部材１を構成しながら、一対の側板部１４内面間の間隔を雌部材１の長さ方向に亙って略均一にした関係から、この雌部材１をプラスチック材料を用い支障なく一体に成形し得るように、かかる側板部１４の厚さをできるだけ均一にするように設けられた肉抜き穴である。
【００３５】
一方、この実施の形態にかかる雄部材２は、前記雌部材１内への板状をなす差し込み部２０と、ベルトなどの帯状体Ｈの取付部２２をを備えており、当該取付部２２は、前記差し込み部２０における差し入れ先側ｘと反対の側、すなわち、差し入れ手前側ｙに一体に設けられている。
【００３６】
この実施の形態にあっては、かかる帯状体Ｈの取付部２２は、前記板状をなす差し込み部２０における差し入れ手前側ｙの両側部においてそれぞれ、この側部から一体に同じ向きに突き出すように設けられた側板部２２ａと、この側板部２２ａの突き出し端側に亙って設けられる横板部２２ｂと、当該横板部２２ｂと前記差し込み部２０の差し入れ手前側ｙの側縁部との間に前記帯状体Ｈの通し空間２２ｄを開けて、前記一対の側板部２２ａ、２２ａ間に亙って設けられる巻き掛け桿２２ｅとを備えている。この実施の形態にあっては、前記横板部２２ｂが、前記雄部材２における前記雌部材１との掛合状態Ｋにおいて当該雌部材１の前板部１２と同じ側に向けられる側（以下、雄部材２の前側２ａという。）から、これと反対の側（すなわち、前記掛合状態Ｋにおいて雌部材１の後板部１３と同じ側に向けられる側、以下、雄部材２の後側２ｂという。）に向けて、次第に雄部材２の差し込み部２０の側に近付く向きに板面を傾斜させた構成としてあり、図１９に示されるように、前記巻き掛け桿２２ｅを挟んだ前記差し込み部２０側にある前記通し空間２２ｄと前記横板部２２ｂ側にある前記通し空間２２ｄとに、前記雄部材２の前側２ａで前記巻き掛け桿２２ｅに巻き掛けられるように通された帯状体Ｈに対し、特に、前記巻き掛け桿２２ｅにおける前記横板部２２ｂ側にある隅部２２ｆと雄部材２の後側２ｂにある当該当該横板部２２ｂの端部２２ｃとを突き当てて、当該帯状体Ｈをズレなく留め付けるように、前記のように通された当該帯状体Ｈを屈曲させる構成としてある。
【００３７】
また、前記板状をなす差し込み部２０は、前記雌部材１の両側板部１４、１４間に当該側板部１４に差し入れ方向Ｓに沿った側端面２０ａをガイドされながら差し入れられる大きさに構成されている。
【００３８】
また、この差し込み部２０における差し入れ手前側ｙの両側部には、前記雌部材１の側方開放部１４ａに入り込み、かつ、当該側方開放部１４ａに臨む雌部材１の側板部１４の端面１４ｃに突き当たる突き当て部２０ｂが形成されており、この突き当たり位置から先への雌部材１内への雄部材２の差し込み部２０を差し入れが阻止される構成としてある。そして、この実施の形態にあっては、かかる雄部材２の突き当て部２０ｂが雌部材１の側板部１４の端面１４ｃに突き当たる雄部材２の差し込み部２０の雌部材１内への差し込み位置が、前記雌部材１の掛合部１５とされる段差面１７ｃに雄部材２の弾性片２１の先端部２１ａを掛合させる所定の差し込み位置Ｒとされている。
【００３９】
また、この実施の形態にあっては、前記差し込み部２０に、当該差し込み部２０を貫通するように割溝２１ｄが設けられており、この割溝２１ｄにより区分される箇所が前記弾性片２１とされている。
【００４０】
すなわち、この実施の形態にあっては、前記差し込み部２０における差し入れ方向Ｓに沿って、間隔を開けて二条の縦側割溝２１ｄ’、２１ｄ’が設けてあると共に、この二条の縦側割溝２１ｄ’、２１ｄ’における当該差し込み部２０の差し入れ手前側ｙの溝端間に亙って当該二条の縦側割溝２１ｄ’、２１ｄ’にそれぞれ連通する横側割溝２１ｄ”が前記差し込み部２０の幅方向に向けて設けてある。そして、これにより、当該差し込み部２０における差し入れ手前側ｙを先端部２１ａとする板状の弾性片２１が形成されている。
【００４１】
かかる弾性片２１は、前記差し込み部２０の幅広側の面と略平行をなすように延びる基部２１ｅを有すると共に、先端側に、前記雌部材１への当該差し込み部２０の差し入れ先側ｘから差し入れ手前側ｙに向けて、次第に当該雌部材１の前記前板部１２側に近付く向きの傾斜を備えた傾斜部２１ｆを備えている。そして、この傾斜部２１ｆにより、雄部材２の前記前側２ａに、前記掛合状態Ｋにおいて押し込み操作された雌部材１の操作片１６の先端側が突き当てられる当接面２１ｃが形成されている。
【００４２】
また、雄部材２における前記後側２ｂにある前記差し込み部２０の面と、この雄部材２の前記前側２ａにある前記弾性片２１の先端部２１ａとの間の、当該差し込み部２０の厚さ方向に向けた寸法ｔ１が、少なくとも雌部材１における前記突き出し部１７の頂端１７ｂ側における案内面１７ａと後板部１３の内面との間の間隔ｔ２よりも、大きくなるように構成してある。
【００４３】
また、前記所定の差し込み位置Ｒにおいて、雄部材２の差し込み部２０における前記弾性片２１の先端部２１ａが、雌部材１の前記段差面１７ｃの直下に位置される構成としてある。なお、この弾性片２１の先端部２１ａには、前記差し込み部２０の差し入れ手前側ｙに向けられた掛合面２１ｂが形成してある。
【００４４】
この結果、この実施の形態にあっては、先ず、前記雌部材１における前記差し込み開口１１から前記雄部材２の前記差し込み部２０を、この差し込み部２０における雄部材２の前側２ａが雌部材１の前板部１２の内面に向き合う向きで差し入れることができると共に、この差し入れに伴って前記雌部材１の突き出し部１７における案内面１７ａに雄部材２の弾性片２１の先端部２１ａを摺接させて当該弾性片２１を次第に雄部材２の前記後側２ｂに向けて撓み込ませることができる。（図２０）
【００４５】

【００４６】
次いで、かかる掛合状態Ｋから、前記操作片１６を押し込み操作することにより、この操作片１６における先端側の内面を前記弾性片２１の当接面２１ｃに突き当て、当該弾性片２１を前記雄部材２の後側２ｂに向けて撓み込ませ、この弾性片２１の先端部２１ａと前記突き出し部１７の段差面１７ｃとの掛合を解くことができる。（図２２）
【００４７】
ここで、かかる雄部材２の弾性片２１における前記当接面２１ｃは前記傾斜を備えていることから、この傾斜により前記操作片１６による当該弾性片２１を介した当接、押圧を受ける雄部材２は、雌部材１の差し入れ開口１０側に向けて前記掛合状態Ｋの解除と同時に移動される。（図２３）
【００４８】
この結果、前記雌部材１の操作片１６の押し込み操作により一旦前記掛合状態Ｋが解除された前記雄部材２の弾性片２１が、この解除後かかる操作片１６の押し込み操作を止めても、つまり、当該操作片１６が所期の位置に弾性復帰しても、再び前記突き出し部１７の段差面１７ｃに掛合されることがないようにすることができる。
【００４９】
かかる操作片１６の押し込み操作に伴う雄部材２の移動寸法は、前記弾性片２１の当接面２１ｃの当該雄部材２の差し入れ部の差し入れ方向Ｓに向けた長さや、当該当接面２１ｃの傾斜角を変えることにより適宜変更することができる。この実施の形態にあっては、前記掛合状態Ｋを解くストロークの前記操作片１６の押し込み操作により、前記弾性片２１の先端部２１ａが前記突き出し部１７における頂端１７ｂを越えて当該突き出し部１７における前記案内面１７ａの側に至るストロークで前記雄部材２の移動がされるように、前記当接面２１ｃの長さ、傾斜角が設定されている。
【００５０】
次いで、前記操作片１６の押し込み操作により前記掛合状態Ｋが解かれ、前記雌部材１の案内面１７ａに弾性片２１の先端を突き当てる位置まで移動された雄部材２は、この案内面１７ａにおける前記頂端１７ｂ側の箇所と前記後板部１３の内面間の間隔ｔ２が、前記差し込み部２０の雄部材２の後側２ｂの面と弾性片２１の先端部２１ａ間の寸法ｔ１よりも狭いことから、かかる弾性片２１の先端部２１ａを前記案内面１７ａに突き当てながらなされる当該弾性片２１の弾性復帰方向への移動に伴って、前記雌部材１の差し入れ開口１０から前記差し込み部２０を抜き出させる向きにさらに移動され、（図２４）これにより、雌部材１と再び完全に分離される。（図１９）
【００５１】
なお、この実施の形態にあっては、前記雄部材２の差し込み部２０における弾性片２１を挟んだ当該差し込み部２０の差し入れ方向Ｓに沿った両側部２３、２３が、雌部材１への差し入れに伴って当該雌部材１の前板部１２および後板部１３に摺接される厚さに構成してあり、当該差し込み部２０の雌部材１内への差し入れを安定ならしめると共に、前記掛合状態Ｋにおいてガタつきを生じ難いようにしてある。
【００５２】
また、雄部材２の差し込み部２０における差し入れ先側ｘにおいて、当該雄部材２の前側２ａにある当該差し込み部２０先端面に、差し入れ手前側ｙに向けて高まるテーパ面２４が形成してあり、雌部材１内への差し入れをスムースに行えるようにしてある。
【００５３】
前記雄部材２における弾性片２１、前記雌部材１における操作片１６への所要の弾性変形特性の付与は、少なくとも、当該弾性片２１、操作片１６部分をプラスチック材料、ゴム材料、弾性変形特性を備えた金属材料などにより構成することによりなされる。バックルを低廉に構成するなどの観点からは、当該雄部材２および雌部材１の双方全体をプラスチック材料により一体に成形して構成することが好ましい。
【００５４】
【発明の効果】
この発明にかかるバックルによれば、雌部材の前板部に区分して設けられた操作片の押し込み操作により雄部材の差し込み部における弾性片と雌部材の掛合部との掛合を解くと共に、当該弾性片における前記操作片への当接面の傾斜により前記雄部材を雌部材内から抜け出す向きに移動させることができる。
【００５５】
特に、片手の指一本で前記操作片を押し込み操作することのみをもって、前記雄部材と雌部材との掛合の解除・分離を円滑になすことができる特長を有する。
