【発明の属する技術分野】
本発明はスライドファスナーに関し、例えば衣服、かばん、袋物、くつ、寝具、テント等の開口部を開閉するのに使用され、開閉に際し、務歯が裏地に噛み合うのを防止して開閉操作を迅速かつ円滑に行うためのものである。
【０００２】
【従来の技術】
従来、例えばコート、上着、ジャンパー、ズボン、スキーウェアー等の衣服、またかばん、袋物、くつ、寝具、テント等の開口部を開閉するのにスライドファスナーが使用されていた。このスライドファスナーには例えば従来、図１５ないし図１９に示すものがあった。
すなわち、左右１対のストリンガーｂ，ｂのテープｃ，ｃに固着した務歯ｄ１，ｄ２を開閉操作するには、引手ｅを有するスライダーａを閉方向側Ａ′または開方向側Ｂ′に移動操作させることにより、このスライダーａの前後に設けた務歯ｄ１，ｄ２を導入するか、または導出させる開口部ｆ，ｇの何れか内に務歯ｄ１，ｄ２を導入して左右の務歯ｄ１，ｄ２相互を噛み合わせるか、または他側の開口部ｇ，ｆの何れかから務歯ｄ１，ｄ２を導出して務歯ｄ１，ｄ２の噛み合いを解いて左右１対の務歯ｄ１，ｄ２の開閉操作を行うものである。
【０００３】
またほかのスライドファスナーの従来例として例えば図２０および図２１に示すものがある。
すなわち、スライダーａ′の務歯ｄ１，ｄ２を導入するか、または導出させる開口部ｆ′，ｇ′に対して前部に位置するような断面略スプーン状の分離板ｉをスライダーａ′の底部に設けることにより、この分離板ｉにより裏地ｈ′等を下方へ押下げて開口部ｆ′内に務歯ｄ１，ｄ２を導入して閉じるものである。
【０００４】
さらに、ほかの従来例として図２２に示すように、スライダーａ″の下面にテーパを外周に形成した略皿状の滑盤ｉ″を装着したものがあった。この従来例は、滑盤ｉ″により袋物に詰めた内容物としての布ｈ″等を下方へ押下げ、務歯ｄ１，ｄ２ないしはスライダーａ″との絡み込みを無くそうとするものである。
【０００５】
【発明が解決しようとする課題】
しかしながら図１５ないし図１９に示す上記従来のスライドファスナーは、スライダーａを移動操作させて左右１対の務歯ｄ１，ｄ２の開閉操作を行うのに、図１５，図１６，図１７に示すようにスライダーａを閉方向に移動した場合には、務歯ｄ１，ｄ２とスライダーａの閉方向側Ａ′の開口部ｆとの間に間隙ｋが形成されるので、この間隙ｋ内に裏地ｈ，ｈが入り込み、不用意に噛み合うため、スライダーａが務歯ｄ１，ｄ２に対して動かなくなり、務歯ｄ１，ｄ２の閉止操作に支障をきたしていた。また、図１８に示すようにスライダーａを開方向に移動した場合には、務歯ｄ１，ｄ２とスライダーａの開方向側Ｂ′の開口部ｇとの間に間隙ｋ′が形成されるので、この間隙ｋ′内に裏地ｈ，ｈが入り込み、不用意に噛み合うため、同様にスライダーａが務歯ｄ１，ｄ２に対して動かなくなり、務歯ｄ１，ｄ２の開操作に支障をきたしていた。
このように、従来のスライドファスナーでは、務歯ｄ１，ｄ２の開閉操作を行うためにスライダーａを閉方向側Ａ′または開方向側Ｂ′に移動させた場合に、務歯ｄ１，ｄ２とスライダーａの前後の開口部ｆ，ｇとの間に間隙ｋ，ｋ′が形成されるので、裏地ｈ，ｈが噛み合い易くなり、スライダーａの開閉操作が円滑かつ迅速に行えなかった。しかも、一度、裏地ｈ，ｈが務歯ｄ１，ｄ２に噛み合うと、噛み合いを解いてスライダーａを自由に移動させるのに多くの時間と労力が必要になるという不都合があった。
【０００６】
また図２０および図２１に示す上記従来のスライドファスナーは、スライダーａ′の開口部ｆ′に対して前部に位置する断面略スプーン状の分離板ｉをスライダーａ′の底部に設けたものは、分離板ｉにより裏地ｈ′等を下方へ押下げながら開口部ｆ′内に務歯ｄ１，ｄ２を導入して閉じるものに過ぎない。そして、分離板ｉの先端と開口部ｆ′との距離ｌが離れて設けられているので、開口部ｆ′と務歯ｄ１，ｄ２との間に生ずる間隙ｋをなくすための何らの手段は施されてはいない。しかも、分離板ｉは平面扇形であり、断面略スプーン状に形成されるので、スライダーａ′が移動するのに伴い左右に裏地ｈ′を押し分けて開口部ｆ′内への絡み付きを防止するという何らの工夫は施されてはいない。このため、裏地ｈ′を形成するための成形材料が軟らかいものであったり、または薄い成形材料により形成されている場合には、裏地ｈ′が撓んで屈曲されたり、或いは断面スプーン状の分離板ｉの上面の凹み内に屈曲されて巻き込まれ易くなる。さらには、勢いよくスライダーａ′を閉方向側Ａ′に移動した場合には、開口部ｆ′内に裏地ｈ′が巻き込まれるので、裏地ｈ′が務歯ｄ１，ｄ２やスライダーａ′に噛み合い、スライダーａ′が移動しなくなる。
【０００７】
さらに、図２２に示す上記従来例のように、スライダーａ″の下面にテーパを外周に形成した略皿状の滑盤ｉ″を装着したものは、滑盤ｉ″により袋物に詰めた内容物としての布ｈ″等を下方へ押下げるのに過ぎないので、同様に滑盤ｉ″の先端と開口部ｆ″との距離ｌ′が離れ、開口部ｆ″と務歯ｄ１，ｄ２との間に生ずる間隙ｋをなくすための何らの手段は施されてはいないため、務歯ｄ１，ｄ２ないしはスライダーａ″との絡み付きを無くそうとするものである。しかも、滑盤ｉ″は全体形状が平坦な皿状に形成されているのに過ぎないので、図１９および図２１のスライダーａ″の移動に伴い左右に裏地ｈ″を押し分けて開口部ｆ″内への絡み付きを防止するのには不充分である。
【０００８】
本発明は上記従来の欠点を解決するとともに務歯とスライダーの務歯を開閉する開口部との間に生ずる間隙を無くし、裏地の侵入による不用意な噛み合いを防止し、務歯の開閉操作を円滑かつ迅速に行うようになしてスライダーの移動の自由度を保証し、構造簡単にして製作および組付が容易であり、量産可能で製作コストが安価なスライドファスナーを提供しようとする。

【００１８】
【発明の実施の形態】
以下、図面に従って本発明の実施の形態の具体例を説明する。
図１乃至図９は本発明の第１実施形態を示し、１は金属または合成樹脂等の剛性材により形成され、左右１対の務歯２Ａ，２Ｂを開閉するために移動されるスライダーであり、このスライダー１の前後には閉方向側Ａまたは開方向側Ｂに務歯２Ａ，２Ｂを一端から導入し、他端から排出するような開口部３，４が形成される。
【００１９】
５は務歯２Ａ，２Ｂを開閉するスライダー１の下部に務歯２Ａ，２Ｂの下面に接触しながら裏地６，６との間に進入可能に設けられた分離板であり、この分離板５は金属または合成樹脂等の剛性と平滑性とを有する形成材料により形成される。また、分離板５の前面および後面には閉方向側Ａまたは開方向側Ｂに設ける開口部３，４の少なくとも何れか、本実施形態では閉方向側Ａおよび開方向側Ｂに設ける開口部３，４に対して底部７Ａが先窄まりで立上がり部７Ｂの外形状が後方へ増大するようなそり上がった壁面部７，７が形成される。
前記壁面部７，７は、スライダー１を閉方向側Ａまたは開方向側Ｂに移動することにより務歯２Ａ，２Ｂの開閉操作を行う時に裏地６，６を左右に押分けることによりスライダー１の開口部３，４と左右の務歯２Ａ，２Ｂとの間に裏地６，６が侵入するような間隙を無くして務歯２Ａ，２Ｂまたはスライダー１に対する裏地６，６の噛み合いを防止するためのものである。
【００２０】
また、前記壁面部７，７は、スライダー１の閉方向側Ａまたは開方向側Ｂに務歯２Ａ，２Ｂを開閉可能に設ける開口部３，４よりも前端または後端が幅狭に形成されることにより務歯２Ａ，２Ｂの開閉操作時に裏地６，６との間に進入して裏地６，６を左右に押分け、スライダー１の開口部３，４と務歯２Ａ，２Ｂとの間に裏地６，６が侵入するのを有効に阻止してスライダー１の噛み合いを有効に防止する。
【００２１】
前記立上がり部７Ｂは、分離板５の前端および後端に側面所望角度θ１、図１，図３に示すように本実施形態では略１５°〜３０°にて設置される正面略逆台形の端部傾斜面部９と、該端部傾斜面部９の左右両側に図４、図５に示すように正面所望角度θ２、図示する本実施形態ではそれぞれ略４５°に連設された側面逆三角形の左右の傾斜側面部１０，１０とにより形成される。このように、分離板５の前端および後端に側面所望角度θ１にて正面略逆台形をなした端部傾斜面部９と、該端部傾斜面部９の左右両側には正面所望角度θ２に側面逆三角形の傾斜側面部１０，１０とを連設したのは、分離板５の前端および後端が裏地６，６との間に円滑かつ確実に進入するようにするためと、左右に設置配置した傾斜側面部１０，１０により分離板５の外容積が前端および後端から漸次増大するようにして分離板５による裏地６，６の押分けを確実にするためである。
【００２２】
また、前記分離板５は、スライダー１と一体に形成されるか、またはスライダー１とは別体に形成されて適宜固着手段１１によりスライダー１の下面に取付けられる。この際、固着手段１１としては、スライダー１と分離板５とが共に金属により形成される場合には、溶接により取付が行われるか、接着剤を用いた接着によったり、嵌着したり、加締めにより取付が行われる。また、スライダー１と分離板５とが共に合成樹脂により形成される場合には、高周波溶着によったり、嵌合したり、接着剤を用いて接着することによりスライダー１の下面に分離板５が取付られる。
【００２３】
さらに、スライダー１が金属で形成され、分離板５が合成樹脂により形成される等、それぞれ異質の成形材料により形成される場合には、固着手段１１としては例えば図７および図８に示すようにスライダー１の下面に、スライダー１の外形状より小形であり適宜個数の爪１２ａを外周に有する突条部１２を形成し、また分離板５の上面には前記突条部１２が嵌合される凹部１３を設けるとともに前記爪１２ａが係合される爪受１３ａを凹部１３の対応個所にそれぞれ形成する。そして、取付には突条部１２を凹部１３内に嵌合し、爪１２ａを爪受１３ａに係合させてスライダー１の下面に分離板５を取付ける。
【００２４】
また固着手段１１の他の変形例として、たとえば図９に示すようにスライダー１の下面に爪１２ａを有した突条部１２を設け、また前記爪１２ａが係合される爪受１４ａを内周の対応位置に設けた孔部１４を分離板５を設けたことにより、孔部１４内に突条部１２を嵌合し、爪１２ａを爪受１４ａに係合させることによってスライダー１の下面に分離板５を取付けることもできる。
１５はスライダー１の引手であり、この引手１５の形状、材質の変更は自由に行え、しかもスライダー１に対する取付の変更も自由に行える。また、１６はスライダー１の開口部３，４内に設けられた案内壁である。
【００２５】
本発明の第１実施形態は以上の構成からなり、務歯２Ａ，２Ｂを開閉するにはスライダー１を開方向側Ａまたは閉方向側Ｂに移動することは従来と同様である。
【００２６】
しかしながら、本実施形態では例えば図１の実線に示すように引手１５を引いてスライダー１を務歯２Ａ，２Ｂに対して閉方向に移動すると、スライダー１の下部に設けた分離板５の前端および後端に形成される壁面部７の端部傾斜面部９の上端がスライダー１と一緒に務歯２Ａ，２Ｂの下面に接触しながら移動して行く。
このため、図１５ないし図１９に示す従来のスライドファスナーとは異なりスライダー１の閉方向側Ａに設けた開口部３と務歯２Ａ，２Ｂとの間に生ずる間隙を無くすことができるので、裏地６，６が開口部３内に入り込む余地はない。
また、スライダー１は、分離板５により背面が覆われるので、スライドファスナーを衣服などに装着した場合に、身体に違和感などを覚えることなく、またスライダー１の移動操作の邪魔になることもない。
【００２７】
この際、図１，図２に示すようにスライダー１を移動するのに伴って分離板５の壁面部７は、立上がり部７Ｂの前端および後端には正面略逆台形の端部傾斜面部９が側面所望角度θ１にそり上がって形成されるので、この端部傾斜面部９が務歯２Ａ，２Ｂと裏地６，６との間に迅速かつ確実に進入されて行く。
【００２８】
しかも、立上がり部７Ｂは、端部傾斜面部９を中央にしてその左右両側に正面所望角度θ２に側面逆三角形の傾斜側面部１０，１０が連設されることにより分離板５の外形が前端から漸次増大するように形成されるので、中央の端部傾斜面部９と左右両側に連設される傾斜側面部１０，１０との協同した推力により裏地６，６との間に分離板５が円滑かつ確実に進入するため、裏地６，６は務歯２Ａ，２Ｂとの接触が断たれて効率的に左右に分担して押分けられる。また、上述のように分離板５の前端の壁面部７は外形が前端から漸次増大するように形成されて図２０および図２１に示す従来のスライドファスナーのように、断面略スプーン状に形成されず、しかも分離板５の壁面部７における端部傾斜面部７Ｂの上端は務歯２Ａ，２Ｂの下面に接触しながら移動して行くので、図２０および図２１に示す従来のスライドファスナーとは異なりスライダー１の閉方向側Ａに設けた開口部３と務歯２Ａ，２Ｂとの間に生ずる間隙を無くすことができる。
このため、裏地６，６を形成するための成形材料が軟らかいものであったり、または薄い成形材料により裏地６，６が形成されている場合に、裏地６，６が撓んで分離板５の上面に屈曲されたり、或いは分離板５の上面に屈曲されて巻き込まれることなく、さらには、勢いよくスライダー１を閉方向側Ａに移動した場合に、開口部３内に裏地６，６が巻き込まれることはない。従って、務歯２Ａ，２Ｂの閉操作時にスライダー１の開口部３と務歯２Ａ，２Ｂとの間へ裏地６，６が侵入されるのを壁面部７により阻止でき、裏地６，６の抵抗が少なく、スライダー１は自由に移動するため、務歯２Ａ，２Ｂの閉操作は円滑かつ確実に行われる。
【００２９】
また、この壁面部７は、スライダー１の閉方向側Ａに設ける開口部３よりも前端が幅狭に形成されるので、務歯２Ａ，２Ｂの閉操作時に裏地６，６を左右に効率良く押分けてスライダー１の開口部３と務歯２Ａ，２Ｂとの間への裏地６，６の侵入を有効に阻止してスライダー１の噛み合いは有効に防止される。
【００３０】
また、務歯２Ａ，２Ｂの開操作を行うには、図１の想像線に示すように引手１５を引いて今度はスライダー１を務歯２Ａ，２Ｂに対して開方向Ｂに移動すると、スライダー１の下部に設けた分離板５の後端に形成される壁面部７の端部傾斜面部９の上端がスライダー１と一緒に務歯２Ａ，２Ｂの下面に接触しながら移動して行く。このため、図１５ないし図１９に示す従来のスライドファスナーとは異なりスライダー１の開方向側Ｂに設けた開口部４と務歯２Ａ，２Ｂとの間に生ずる間隙を分離板５の後端の壁面部７が進入することにより無くすことができるので、裏地６，６が開口部４内に入り込む余地はない。
【００３１】
しかも、開方向へスライダー１が移動するのに伴って分離板５の後端の壁面部７は前述の閉操作時と同様に務歯２Ａ，２Ｂの下面に接触しながら裏地６，６との間に進入されて行くので、裏地６，６は左右に押し分けられる。従って、務歯２Ａ，２Ｂの開操作時にスライダー１の開口部４と務歯２Ａ，２Ｂとの間に裏地６，６が侵入されるのを分離板５の壁面部７により阻止できるため、スライダー１の噛み合いを防止することができる。
【００３２】
この際、壁面部７は、分離板５の後端に設置される正面略逆台形の端部傾斜面部９が側面所望角度θ１にそり上がって形成されているので、分離板５の後端に設置される正面略逆台形の端部傾斜面部９は務歯２Ａ，２Ｂと裏地６，６との間に間隙を生ずることなく迅速かつ確実に進されて行く。しかも、壁面部７は、端部傾斜面部９を中央にしてその左右両側に正面所望角度θ２に側面逆三角形の傾斜側面部１０，１０がそれぞれ連設されることにより外形が後端から漸次増大するように形成されるので、中央の端部傾斜面部９と左右の傾斜側面部１０，１０との協同した推力により裏地６，６は分離板５により務歯２Ａ，２Ｂとの接触が断たれ、左右に効率的に分担して押分けられるため、裏地７，７の抵抗が少なくなりスライダー１は自由に移動され、務歯２Ａ，２Ｂの開操作は円滑に行われる。
【００３３】
また、この壁面部７の後端は、スライダー１の開方向側Ｂに設ける開口部４よりも幅狭に形成されるので、務歯２Ａ，２Ｂの開操作時に裏地６，６を左右に効率良く押分けてスライダー１の開口部４と務歯２Ａ，２Ｂとの間へ分離板５が進入されることにより裏地６，６が開口部４内に侵入するのを有効に阻止してスライダー１の噛み合いを有効に防止することができる。
【００３４】
図１０乃至図１４に示すものは本発明の第２実施形態である。
この実施形態では、前記壁面部７は、スライダー１の底部を閉方向側Ａの開口部３よりも前方へ延長させた第１延出端２０，２０として形成するとともに該第１延出端２０，２０の上面には前記開口部３の前部に位置して設けられる平面先窄まりの案内立壁部２１，２１が形成され、開方向側Ｂには開口部４よりも後方へ延長させた第２延出端２２，２２が形成されている。
【００３５】
そして、務歯２Ａ，２Ｂの閉操作を行うためにスライダー１を閉方向側Ａに移動すると、スライダー１の底部を閉方向側Ａの開口部３よりも前方へ延長させた第１延出端２０，２０の上面に平面先窄まりの案内立壁部２１，２１を設けているので、開口部３と務歯２Ａ，２Ｂとの間に生ずる間隙を最小限にできるため、裏地６，６が開口部３内に入り込むのが案内立壁部２１，２１により阻止される。しかも、スライダー１の底部を閉方向側Ａの開口部３よりも前方へ延長させた第１延出端２０を形成しているので、この第１延出端２０が務歯２Ａ，２Ｂとの間に進入されながらスライダー１と一緒に移動するため、裏地６，６は左右に押分けられる。従って、務歯２Ａ，２Ｂの閉操作時にスライダー１の開口部３と務歯２Ａ，２Ｂとの間に裏地６，６が侵入されるのを阻止できるため、スライダー１の噛み合いは防止される。
【００３６】
また、務歯２Ａ，２Ｂの開操作を行うには、スライダー１の開方向側Ｂに開口部４よりも後方へ延長させた第２延出端２２，２２を形成しているので、スライダー１を開方向側Ｂに移動すると、第２延出端２２，２２がスライダー１の底部の開方向側Ｂの開口部４よりも前方へ延長されて位置されるため、開口部４と務歯２Ａ，２Ｂとの間に生ずる間隙は最小限になる。しかも、開方向側Ｂの開口部４よりも前方へ第２延出端２２，２２が延長して形成されるので、この第２延出端２２，２２が務歯２Ａ，２Ｂとの間に進入されながらスライダー１と一緒に移動するため、裏地６，６は左右に押分けられる。従って、務歯２Ａ，２Ｂの開操作時にスライダー１の開口部４と務歯２Ａ，２Ｂとの間へ裏地６，６が侵入されるのを阻止できるため、スライダー１の噛み合いは防止される。
【００３７】
なお、前記第１実施形態において、分離板５の前端および後端に設けられる端部傾斜面部９を設定する角度θ１を略１５°〜４５°とし、しかも端部傾斜面部９の左右に連設される左右の傾斜側面部１０，１０を設置する角度θ２を正面４５°としたが、これらの角度θ１，θ２は、裏地６，６が硬いか軟らかいか、または厚いか薄いか等に応じて自由に増減変更が行われ、好適なものが選択される。
【００３８】
また前記第１実施形態においては、スライダー１の下部に取付た分離板５の前端および後端に底部７Ａが先窄まりで立上がり部７Ｂの外形が後方へ漸次増大するようにそり上がった壁面部７，７が形成されたことにより務歯２Ａ，２Ｂとスライダー１の開口部３，４との間に生ずる間隙を無くし、裏地６の侵入による不用意な噛み合いを防止するようにしているが、この壁面部７，７は図には示さないが分離板５の前端および後端の何れか一側に形成されるものであってもよい。
【００３９】
また前記第２実施形態では、スライダー１の底部の前部に、平面先窄まりの案内立壁部２１，２１を形成したことによりスライダー１の開口部３との間に生ずる間隙を無くし、裏地６の侵入による不用意な噛み合いを防止するようにしているが、案内立壁部２１，２１は図には示さないがスライダー１の前部および後部に設けた開口部３，４の何れか一方に形成されるものであってもよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slide fastener, and is used for opening and closing openings of clothes, bags, bags, shoes, bedding, tents, and the like. This is for smooth operation.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, slide fasteners have been used to open and close openings of clothes such as coats, outerwear, jumpers, pants, and ski wear, as well as bags, bags, shoes, bedding, and tents. For example, the slide fastener shown in FIGS. 15 to 19 has been conventionally used.
That is, in order to open and close the teeth d1 and d2 fixed to the tapes c and c of the pair of left and right stringers b and b, the slider a having the handle e is moved to the closing direction A 'or the opening direction B'. By operating, the service teeth d1 and d2 provided before and after the slider a are introduced, or the service teeth d1 and d2 are introduced into any of the openings f and g to be led out, and the left and right service teeth d1 are introduced. , D2 are meshed with each other, or the engagement teeth d1, d2 are derived from one of the openings g, f on the other side to disengage the engagement of the engagement teeth d1, d2 to form a pair of left and right engagement teeth d1, d2. The opening and closing operation is performed.
[0003]
Other examples of conventional slide fasteners include those shown in FIGS. 20 and 21, for example.
That is, the separation plate i having a substantially spoon-shaped cross section is positioned at the front of the opening f ', g' for introducing or leading the engagement teeth d1, d2 of the slider a 'to the bottom of the slider a'. In this configuration, the lining h 'and the like are pushed down by the separating plate i, and the engagement teeth d1 and d2 are introduced into the opening f' and closed.
[0004]
Further, as another conventional example, as shown in FIG. 22, there is a slider a ″ in which a substantially dish-shaped sliding disk i ″ having a taper formed on the outer periphery is mounted on a lower surface of a slider a ″. In this conventional example, a cloth h "or the like as a content packed in a bag is pushed down by a sliding disk i" so as to eliminate entanglement with the engagement teeth d1, d2 or the slider a ".
[0005]
[Problems to be solved by the invention]
However, in the conventional slide fastener shown in FIGS. 15 to 19, the slider a is moved to open and close the pair of right and left engagement teeth d1 and d2, but as shown in FIGS. 15, 16 and 17. When the slider a is moved in the closing direction, a gap k is formed between the engagement teeth d1 and d2 and the opening f on the closing direction side A 'of the slider a. , H enter and inadvertently mesh with each other, so that the slider a does not move with respect to the engagement teeth d1 and d2, which hinders the closing operation of the engagement teeth d1 and d2. When the slider a is moved in the opening direction as shown in FIG. 18, a gap k 'is formed between the engagement teeth d1 and d2 and the opening g on the opening direction side B' of the slider a. Since the linings h, h enter the gap k 'and inadvertently mesh with each other, the slider a similarly does not move with respect to the engagement teeth d1, d2, which hinders the opening operation of the engagement teeth d1, d2. .
As described above, in the conventional slide fastener, when the slider a is moved to the closing direction A 'or the opening direction B' in order to open and close the teeth d1 and d2, the sliders d and d2 Since gaps k and k 'are formed between the openings f and g before and after a, the linings h and h are easily engaged with each other, and the opening and closing operation of the slider a cannot be performed smoothly and quickly. In addition, once the linings h, h mesh with the engagement teeth d1, d2, there is a disadvantage that much time and labor are required to release the engagement and move the slider a freely.
[0006]
The conventional slide fastener shown in FIGS. 20 and 21 has a separation plate i having a substantially spoon-shaped cross section located at the front with respect to the opening f 'of the slider a' at the bottom of the slider a '. In this case, the engagement teeth d1 and d2 are merely introduced into the opening f 'and closed by pushing down the lining h' and the like by the separating plate i. Since the distance 1 between the tip of the separation plate i and the opening f 'is provided at a distance, any means for eliminating the gap k generated between the opening f' and the engagement teeth d1 and d2 is required. Not implemented. In addition, since the separating plate i has a flat sector shape and is formed in a substantially spoon-shaped cross section, the lining h 'is pressed to the left and right as the slider a' moves, thereby preventing the entanglement in the opening f '. No ingenuity has been applied. For this reason, when the molding material for forming the lining h 'is soft or formed of a thin molding material, the lining h' is bent and bent, or the separation plate having a spoon-shaped cross section. It is easy to bend and get caught in the recess on the upper surface of i. Further, when the slider a 'is vigorously moved to the closing direction side A', the lining h 'is caught in the opening f', so that the lining h 'meshes with the engagement teeth d1, d2 and the slider a'. , The slider a 'does not move.
[0007]
Further, as shown in FIG. 22, a slide plate i ″ having a substantially dished shape with a taper formed on the outer periphery on the lower surface of the slider a ″ is mounted on the bag by the slide plate i ″. Is merely pushed downward, so that the distance l 'between the tip of the sliding disk i "and the opening f" is similarly increased, and the distance between the opening f "and the engagement teeth d1 and d2 is similarly increased. Since no means is provided for eliminating the gap k occurring therebetween, it is intended to eliminate entanglement with the engagement teeth d1, d2 or the slider a ''. Moreover, since the sliding disk i "is merely formed in a flat dish shape as a whole, the lining h" is pushed to the left and right with the movement of the slider a "in FIGS. 19 and 21 to open and close the opening f". It is not enough to prevent entanglement inside.
[0008]
The present invention solves the above-mentioned conventional drawbacks, eliminates the gap between the engaging teeth and the opening for opening and closing the engaging teeth of the slider, prevents inadvertent meshing due to the intrusion of the lining, and opens and closes the engaging teeth. An object of the present invention is to provide a slide fastener that can smoothly and quickly perform, guarantees the freedom of movement of a slider, has a simple structure, is easy to manufacture and assemble, can be mass-produced, and is inexpensive to manufacture.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific examples of the embodiments of the present invention will be described with reference to the drawings.
FIGS. 1 to 9 show a first embodiment of the present invention, wherein 1 is a slider formed of a rigid material such as metal or synthetic resin and moved to open and close a pair of right and left teeth 2A and 2B. Openings 3 and 4 are formed on the front and rear sides of the slider 1 so that the engagement teeth 2A and 2B are introduced from one end and discharged from the other end on the closing direction side A or the opening direction side B.
[0019]
Reference numeral 5 denotes a separation plate provided below the slider 1 for opening and closing the teeth 2A, 2B so as to be able to enter between the linings 6, 6 while being in contact with the lower surfaces of the teeth 2A, 2B. It is formed of a rigid or smooth forming material such as metal or synthetic resin. In addition, at least one of the openings 3 and 4 provided on the closing direction side A or the opening direction side B on the front surface and the rear surface of the separation plate 5, and in the present embodiment, the opening portions 3 provided on the closing direction side A and the opening direction side B. , 4 are formed so that the bottom portion 7A is tapered and the outer shape of the rising portion 7B increases rearward.
When the slider 1 is moved to the closing direction side A or the opening direction side B to open and close the engaging teeth 2A, 2B by moving the slider 1 to the closing direction side A or the opening direction side B, the linings 6, 6 are pushed to the left and right by pushing. A gap between the openings 3 and 4 and the left and right engagement teeth 2A and 2B for preventing the linings 6 and 6 from entering is eliminated to prevent the engagement of the linings 6 and 6 with the engagement teeth 2A and 2B or the slider 1. Things.
[0020]
Further, the front end or the rear end of the wall portions 7, 7 is formed to be narrower than the openings 3, 4 provided on the closing direction side A or the opening direction side B of the slider 1 so as to open and close the engaging teeth 2 A, 2 B. As a result, during opening / closing operation of the working teeth 2A, 2B, it enters between the linings 6, 6 and pushes the linings 6, 6 to the left and right, and between the openings 3, 4 of the slider 1 and the working teeth 2A, 2B. The linings 6 and 6 are effectively prevented from entering, and the engagement of the slider 1 is effectively prevented.
[0021]
The rising portion 7B is provided at a front end and a rear end of the separation plate 5 with a desired side surface angle θ1, and as shown in FIGS. The right and left sides of an inverted triangle formed continuously at a desired inclined angle θ2 as shown in FIGS. 4 and 5 at the right and left sides of the end inclined surface portion 9 and approximately 45 ° in the illustrated embodiment. Are formed by the inclined side surface portions 10, 10. As described above, the front and rear ends of the separation plate 5 have the end inclined surface portion 9 having a substantially inverted trapezoidal front surface at the desired side surface angle θ1 and the left and right sides of the end inclined surface portion 9 have the desired front angle angle θ2. The reason why the inclined side surfaces 10 and 10 of the inverted triangle are continuously provided is that the front end and the rear end of the separation plate 5 smoothly and surely enter between the linings 6 and 6, respectively. The inclined side surfaces 10, 10 increase the outer volume of the separation plate 5 gradually from the front end and the rear end so that the separation plates 5 can reliably press the linings 6, 6.
[0022]
The separating plate 5 is formed integrally with the slider 1 or is formed separately from the slider 1 and is attached to the lower surface of the slider 1 by an appropriate fixing means 11. At this time, when the slider 1 and the separation plate 5 are both formed of metal, the fixing means 11 is attached by welding, or is bonded by using an adhesive, Mounting is performed by swaging. When the slider 1 and the separation plate 5 are both formed of a synthetic resin, the separation plate 5 is attached to the lower surface of the slider 1 by high-frequency welding, fitting, or bonding using an adhesive. Can be attached.
[0023]
Further, when the slider 1 is formed of a different material, such as a case where the slider 1 is formed of a metal and the separation plate 5 is formed of a synthetic resin, as the fixing means 11, as shown in FIGS. 7 and 8, for example. On the lower surface of the slider 1, a ridge portion 12 smaller than the outer shape of the slider 1 and having an appropriate number of claws 12 a on the outer periphery is formed. On the upper surface of the separation plate 5, the ridge portion 12 is fitted. A concave portion 13 is provided, and a claw receiver 13a with which the claw 12a is engaged is formed at a corresponding portion of the concave portion 13, respectively. For mounting, the projection 12 is fitted into the recess 13, and the claw 12 a is engaged with the claw receiver 13 a to attach the separation plate 5 to the lower surface of the slider 1.
[0024]
As another modification of the fixing means 11, for example, as shown in FIG. 9, a ridge 12 having a claw 12a is provided on the lower surface of the slider 1, and a claw receiver 14a to which the claw 12a is engaged is provided on the inner periphery. Is provided on the lower surface of the slider 1 by fitting the projections 12 into the holes 14 and engaging the claws 12a with the claw receivers 14a. A separation plate 5 can be attached.
Reference numeral 15 denotes a handle of the slider 1, and the shape and the material of the handle 15 can be freely changed, and further, the attachment to the slider 1 can be freely changed. Reference numeral 16 denotes a guide wall provided in the openings 3 and 4 of the slider 1.
[0025]
The first embodiment of the present invention is configured as described above, and moving the slider 1 to the opening direction side A or the closing direction side B to open and close the engagement teeth 2A and 2B is the same as in the related art.
[0026]
However, in the present embodiment, when the slider 1 is moved in the closing direction with respect to the engagement teeth 2A and 2B by pulling the handle 15 as shown by a solid line in FIG. 1, for example, the front end of the separation plate 5 provided below the slider 1 and The upper end of the end inclined surface portion 9 of the wall surface portion 7 formed at the rear end moves together with the slider 1 while contacting the lower surfaces of the engagement teeth 2A and 2B.
For this reason, unlike the conventional slide fasteners shown in FIGS. 15 to 19, a gap generated between the opening 3 provided on the closing direction side A of the slider 1 and the engagement teeth 2A, 2B can be eliminated, so that the lining There is no room for 6, 6 to enter the opening 3.
In addition, since the slider 1 is covered on the back with the separating plate 5, when the slide fastener is attached to clothes or the like, the slider 1 does not feel uncomfortable with the body and does not hinder the moving operation of the slider 1.
[0027]
At this time, as shown in FIGS. 1 and 2, as the slider 1 is moved, the wall surface 7 of the separation plate 5 is provided at the front end and the rear end of the rising portion 7B with a substantially inverted trapezoidal front end inclined surface portion 9. Is formed so as to rise to the desired side surface angle θ1, so that the end inclined surface portion 9 quickly and reliably enters between the engagement teeth 2A, 2B and the linings 6, 6.
[0028]
In addition, the rising portion 7B has the end inclined surface portion 9 as a center, and the inclined side surface portions 10 and 10 of the side inverted triangle are continuously provided on both left and right sides at a desired front angle θ2, so that the outer shape of the separation plate 5 from the front end. Since it is formed so as to gradually increase, the separating plate 5 is smoothly interposed between the linings 6 and 6 by the cooperating thrust of the central end inclined surface 9 and the inclined side surfaces 10 and 10 provided on both left and right sides. In order to make sure that the linings 6 and 6 enter, the linings 6 and 6 are cut off from contact with the engagement teeth 2A and 2B and are efficiently divided into right and left. Further, as described above, the wall portion 7 at the front end of the separation plate 5 is formed so that the outer shape gradually increases from the front end, and is formed in a substantially spoon-shaped cross section like the conventional slide fastener shown in FIGS. In addition, since the upper end of the end inclined surface portion 7B of the wall portion 7 of the separation plate 5 moves while contacting the lower surfaces of the engagement teeth 2A and 2B, unlike the conventional slide fastener shown in FIGS. It is possible to eliminate a gap generated between the opening 3 provided on the closing direction side A of the slider 1 and the engagement teeth 2A, 2B.
For this reason, when the molding material for forming the linings 6 and 6 is soft, or when the linings 6 and 6 are formed of a thin molding material, the linings 6 and 6 are bent and the upper surface of the separation plate 5 is formed. When the slider 1 is moved to the closing direction A vigorously without being bent into the upper surface of the separation plate 5 or being rolled up, the linings 6 and 6 are rolled up into the opening 3. Never. Therefore, it is possible to prevent the linings 6, 6 from entering between the opening 3 of the slider 1 and the engaging teeth 2A, 2B by the wall 7 during the closing operation of the engaging teeth 2A, 2B. And the slider 1 moves freely, so that the closing operation of the engagement teeth 2A and 2B is performed smoothly and reliably.
[0029]
In addition, since the front end of the wall portion 7 is formed narrower than the opening 3 provided on the closing direction side A of the slider 1, the linings 6, 6 can be efficiently moved to the left and right during the closing operation of the engagement teeth 2A, 2B. Pushing the slider 1 effectively prevents the linings 6, 6 from entering between the opening 3 of the slider 1 and the engagement teeth 2A, 2B, and the engagement of the slider 1 is effectively prevented.
[0030]
To open the teeth 2A and 2B, the puller 15 is pulled as shown by the imaginary line in FIG. 1 and the slider 1 is moved in the opening direction B with respect to the teeth 2A and 2B. The upper end of the inclined surface portion 9 of the wall portion 7 formed at the rear end of the separation plate 5 provided at the lower portion 1 moves together with the slider 1 while contacting the lower surfaces of the teeth 2A and 2B. For this reason, unlike the conventional slide fastener shown in FIGS. 15 to 19, the gap created between the opening 4 provided on the opening direction side B of the slider 1 and the engagement teeth 2A, 2B is formed at the rear end of the separation plate 5. Since the lining 6 can be eliminated by entering the wall 7, there is no room for the linings 6, 6 to enter the opening 4.
[0031]
In addition, as the slider 1 moves in the opening direction, the rear wall surface 7 of the separation plate 5 contacts the lower surfaces of the teeth 2A and 2B while contacting the lower surfaces of the engaging teeth 2A and 2B in the same manner as in the above-described closing operation. As it enters between, the linings 6, 6 are pushed left and right. Therefore, it is possible to prevent the linings 6, 6 from entering between the opening 4 of the slider 1 and the engaging teeth 2A, 2B by the wall surface 7 of the separation plate 5 at the time of opening the engaging teeth 2A, 2B. 1 can be prevented from engaging.
[0032]
At this time, the wall surface 7 is formed at the rear end of the separation plate 5 because the front inclined surface 9 having a substantially inverted trapezoidal front surface installed at the rear end of the separation plate 5 is formed so as to rise up to the desired side surface angle θ1. The installed front inclined surface 9 having a substantially inverted trapezoidal shape is quickly and reliably advanced without forming a gap between the teeth 2A, 2B and the linings 6, 6. In addition, the outer shape of the wall surface portion 7 gradually increases from the rear end by arranging the inclined side surface portions 10 and 10 of inverted side triangles at the desired front angle θ2 on both left and right sides with the end inclined surface portion 9 as a center. As a result, the linings 6, 6 are disconnected from the engagement teeth 2A, 2B by the separation plate 5 by the cooperating thrust of the center end inclined surface portion 9 and the left and right inclined side surface portions 10, 10. Since the linings 7 and 7 are efficiently divided and pushed to the left and right, the resistance of the linings 7 and 7 is reduced, the slider 1 is freely moved, and the opening operation of the engagement teeth 2A and 2B is performed smoothly.
[0033]
Further, the rear end of the wall portion 7 is formed narrower than the opening 4 provided on the opening direction side B of the slider 1, so that the linings 6, 6 can be efficiently moved to the left and right when the teeth 2 A, 2 B are opened. The separation plate 5 is pushed well between the opening 4 of the slider 1 and the engagement teeth 2A, 2B, so that the linings 6, 6 are effectively prevented from entering the opening 4, and the slider 1 Can effectively be prevented from meshing with each other.
[0034]
FIG. 10 to FIG. 14 show a second embodiment of the present invention.
In this embodiment, the wall portion 7 is formed as first extended ends 20, 20 in which the bottom of the slider 1 is extended forward from the opening 3 on the closing direction side A, and the first extended end 20 is formed. , 20 are formed at the front portion of the opening 3 with guide standing walls 21 and 21 of a flattened shape, which are extended rearward from the opening 4 on the side B in the opening direction. The second extending ends 22, 22 are formed.
[0035]
Then, when the slider 1 is moved to the closing direction side A in order to perform the closing operation of the engagement teeth 2A and 2B, a first extension end in which the bottom of the slider 1 extends forward from the opening 3 on the closing direction side A. Since the guide standing wall portions 21 and 21 having the flattened portions are provided on the upper surfaces of the 20, 20, the gap generated between the opening 3 and the engagement teeth 2A and 2B can be minimized. The entry into the opening 3 is prevented by the guide standing walls 21 and 21. Moreover, since the bottom of the slider 1 is formed with the first extension end 20 extending forward from the opening 3 on the closing direction side A, the first extension end 20 is in contact with the engagement teeth 2A, 2B. The linings 6 and 6 are pushed right and left because they move together with the slider 1 while entering the space. Accordingly, the linings 6, 6 can be prevented from entering between the opening 3 of the slider 1 and the engaging teeth 2A, 2B during the closing operation of the engaging teeth 2A, 2B, so that the engagement of the slider 1 is prevented.
[0036]
In order to perform the opening operation of the engagement teeth 2A and 2B, since the second extension ends 22 and 22 extending rearward from the opening 4 are formed on the opening direction side B of the slider 1, the slider 1 is provided. Is moved to the opening direction side B, the second extension ends 22 and 22 are positioned so as to extend forward from the opening 4 on the opening direction side B at the bottom of the slider 1, so that the opening 4 and the engagement tooth 2A are located. , 2B is minimized. Moreover, since the second extending ends 22, 22 are formed extending forward from the opening 4 on the opening direction side B, the second extending ends 22, 22 are located between the engaging teeth 2A, 2B. The linings 6 and 6 are pushed left and right because they move together with the slider 1 while entering. Therefore, the linings 6, 6 can be prevented from entering between the opening 4 of the slider 1 and the engaging teeth 2A, 2B during the opening operation of the engaging teeth 2A, 2B, so that the engagement of the slider 1 is prevented.
[0037]
In the first embodiment, the angle θ1 for setting the end inclined surface 9 provided at the front end and the rear end of the separation plate 5 is set to approximately 15 ° to 45 °, and furthermore, the angle θ1 is continuously provided on the left and right of the end inclined surface 9. The angle θ2 at which the left and right inclined side surfaces 10, 10 are installed is set to 45 ° in front, and these angles θ1, θ2 depend on whether the linings 6, 6 are hard or soft, or thick or thin. The increase / decrease is freely changed, and a suitable one is selected.
