Description

【０００１】
【発明の属する技術分野】
本発明は、例えば測定装置の接続用端子などにその着脱を自在にして電気的に接続させることができる鰐口クリップを含む各種のクリップに好適な軸支構造に関する技術である。
【０００２】
【従来の技術】
図５は、従来からある鰐口クリップの一例を分解して示す全体斜視図であり、図６は、図５に示す例についての組立て後の姿態を示す全体斜視図である。これらの図によれば、鰐口クリップ１１１は、固定側クリップ片１１２と、該固定側クリップ片１１２と向き合うようにしてその上側に配置される可動側クリップ片１２２と、これら固定側クリップ片１１２と可動側クリップ片１２２とをねじりコイルばね１４２を介装させた合成樹脂材製の支軸部１３２を介して一体的に軸支することによりその全体が形成されている。
【０００３】
このため、可動側クリップ片１２２がその先端側に備える可動側咬持部１２３は、図示しない接続ケーブルの一端側が導入されるケーブルガイド筒部１１５を基端側に備える固定側クリップ片１１２がその先端側に備える固定側咬持部１１３に対し、ねじりコイルばね１４２の付勢力により圧接されて常閉状態となっている。
【０００４】
また、可動側クリップ片１２２は、その基端側に備える操作レバー１２５を押し下げることにより、ねじりコイルばね１４２の付勢力に抗して可動側咬持部１２３を、固定側クリップ片１１２の固定側咬持部１１３から強制的に引き離すことができる。
【０００５】
さらに、固定側咬持部１１３と可動側咬持部１２３とにおけるそれぞれの対面側には、その閉止時に相互に噛合する鋸歯状金属片１１４，１２４が対向配置されている。なお、図示は省略してあるが、固定側咬持部１１３が備える鋸歯状金属片１１４は、導電金属板などからなる導電材を介してケーブルガイド筒部１１５内に導入された接続ケーブルの一端側と電気的に接続できるようになっている。
【０００６】
ところで、図５に示す鰐口クリップ１１１は、固定側クリップ片１１２が備える一対の軸受片部１１６，１１６と、可動側クリップ片１２３が備える一対の軸受片部１２６，１２６とがそれぞれに設けられている軸支孔１１７，１２７を連通させた支軸部１３２を介して一体的に連結されている。
【０００７】
この場合の軸支構造は、固定側クリップ片１１２の各軸受片部１１６の内側に可動側クリップ片１２３の各軸受片部１２６をそれぞれの軸支孔１１７，１２７が相互に連通するように配置した上で、支軸部１３２をその基端部に設けた鍔部１３３が掛止される位置まで軸支孔１１７，１２７を挿通し、反対側から突出した先端部１３４を熱や超音波など適宜の加熱手法により対応する固定側クリップ片１１２の軸受片部１１６から抜けないようにかしめたり、同軸受片部１１６の外側に溶着するなどしてなる固定部１３５により形成されている。
【０００８】
【発明が解決しようとする課題】
しかし、図５に示す軸支構造による場合には、まず、固定側クリップ片１１３の軸受片部１１６が備える軸支孔１１７と、可動側クリップ片１２３の軸受片部１２６が備える軸支孔１２７とが相互に対向して連通する位置関係となるように正しく位置決めして配置する必要がある。しかも、その際、ねじりコイルばね１４２は、そのコイル部１４３を軸支孔１１７，１２７と対面させるとともに、該コイル部１４３から延設された一方の掛止腕部１４４が固定側クリップ片１１２の所定位置に掛止され、他方の掛止腕部１４５が可動側クリップ片１２３の所定位置にそれぞれ掛止した状態で配置されるため、力を加えながら固定側クリップ片１１２と可動側クリップ片１２２とを押さえ付けておく必要があるので、支軸部１３２を挿通させる際の軸支孔１１７，１２７とコイル部１４３とをずれのない煩雑な位置合わせ作業を経なければならず、その組立てに時間がかかる不都合があった。
【０００９】
また、支軸部１３２は、挿通後に突出する先端部１３４を加熱してかしめたり、固定側クリップ片１１２の外側に溶着するなどして固定部１３５を形成することにより抜脱困難に軸支させておく必要があり、作業数がそれだけ増えてしまう不具合もあった。
【００１０】
本発明は、上記した従来技術の課題に鑑み、ねじりコイルばねを介装させた状態で例えば固定側クリップ片としての一側クリップ片と、可動側クリップ片としての他側クリップ片とを簡単に一体化することができる鰐口クリップを含む各種のクリップを提供することを目的とする。
【００１１】
【課題を解決するための手段】
本発明は、上記目的を達成するためになされたものであり、一側クリップ片と、該一側クリップ片と向き合うように配置される他側クリップ片と、コイル部から一方の掛止腕部と他方の掛止腕部とを延設してなるねじりコイルばねとを、前記コイル部に挿通して介装させた支軸材を介して一体的に軸支してなるクリップにおいて、前記他側クリップ片は、表側の大径部と奥側の小径部とを連続させて前記支軸材の挿通を自在に形成した軸支孔を有する一対の軸受片部を備え、これら軸受片部相互間には、一方の前記軸支孔の前記大径部側にその頭部を掛止させて他方の前記軸支孔の側に前記ねじりコイルばねを介装させて到達する軸本体部と、他方の前記軸支孔の前記大径部側にその頭部を掛止させて前記軸本体部の先端部に嵌着ささせた蓋体部とからなる前記支軸材を配置するとともに、前記軸支孔の位置との対応関係のもとで設けた軸受孔を有して撓み変形が可能な一対の軸受片部を備えてなる前記一側クリップ片は、一方の前記軸受孔に前記軸本体部の頭部側を、他方の前記軸受孔に前記蓋体部の頭部側を、それぞれの軸受片部の内面側から導入して嵌着させて前記他側クリップ片と一体化させたことに特徴がある。
【００１２】
本発明における前記支軸材を構成する軸本体部の前記頭部と蓋体部の前記頭部とは、その導入方向での先端縁側が最も肉厚の薄い前傾斜面を具備させるのが好ましい。この場合、軸本体部の前記頭部と該頭部側が掛止される一方の前記軸支孔の前記大径部と、蓋体部の前記頭部と該頭部側が掛止される他方の前記軸支孔の前記大径部とには、それぞれの頭部と、それぞれの軸支孔の前記大径部の対応部位との間で位置決めする位置固定部を各別に設けておくのが望ましい。
【００１３】
さらに、本発明においては、前記一側クリップ片の先端部を一側咬持部とし、前記他側クリップ片の先端部を他側咬持部とし、これら一側咬持部と他側咬持部とを前記ねじりコイルばねを介して常閉方向に付勢させて配設しておくのが望ましい。
【００１４】
【発明の実施の形態】
図１は、本発明の一例についての分解斜視図であり、図２は、組立て後の姿態を開口状態のもとで示す全体斜視図である。
【００１５】
これらの図によれば、クリップ１１は、固定側として下側に配設される一側クリップ片１２と、該一側クリップ片１２と向き合うようにしてその上側に可動側として配置される他側クリップ片２２と、これら一側クリップ片１２と他側クリップ片２２とをコイル部６３から一方の掛止腕部６４と他方の掛止腕部６５とを反対方向に延設してなるねじりコイルばね６２とを、コイル部６３に挿通して介装させた支軸材４２を介して一体的に軸支することで、その全体が形成されている。
【００１６】
このうち、一側クリップ片１２は、先端側に設けられた一側咬持部１３と、基端側に設けられたケーブル導入筒部１４と、これら一側咬持部１３とケーブル導入筒部１４との間に位置する底板部１５の長さ方向での両側縁部１５側に撓み変形可能に略平行となって立設された一対の軸受片部１７，１７とを備えて一体に形成されている。
【００１７】
また、一側咬持部１３側の底板部１５上には、縦列方向に２個の突起１８が設けられており、これらの各突起１８との対応位置に設けられた図示しない掛止孔を有する鋸歯状金属片１９がその歯部１９ａを上に向け、かつ、掛止孔に突起１８を掛止させて位置ずれを防止した状態で配設されている。
【００１８】
一方、他側クリップ片２２は、先端側に設けられた他側咬持部２３と、基端側に設けられた操作レバー部２４と、これら他側咬持部２３と操作レバー部２４との間に位置する天板部２５の長さ方向での両側縁部２６側に撓み変形可能に略平行となって垂設された一対の軸受片部２７，２７とを備えて一体に形成されている。
【００１９】
また、他側咬持部２３側の底板部２５上には、縦列方向に２個の突起２８が設けられており、これらの各突起２８との対応位置に設けた掛止孔３０を有する鋸歯状金属片２９がその歯部２９ａを下に向け、かつ、掛止孔３０に突起２８を掛止させて位置ずれを防止した状態で配設されている。
【００２０】
本実施形態において、一側クリップ片１２が備える一対の軸受片部１７，１７相互間には、他側クリップ片２２が備える一対の軸受片部２７，２７の導入が自在な空間部１２ａを、他側クリップ片２２が備える一対の軸受片部２７，２７相互間には、ねじりコイルばね６２の収容が自在な空間部２２ａを、それぞれが確保できる配置関係で形成されている。
【００２１】
図３は、他側クリップ片２２に対する支軸材４２とねじりコイルバネ６２との配置関係を示す分解斜視図である。また、図４は、図３に示す各部材を組み付けた後の他側クリップ片２２の状態を示す説明図であり、そのうちの（ａ）は側面図を、（ｂ）は（ａ）のＡ−Ａ線矢視方向での縦断面図をそれぞれ示す。
【００２２】
これらの図によれば、他側クリップ片２２が備える一対の軸受片部２７，２７の適位置には、相互に対面する位置関係で軸支孔３１がそれぞれ形成されている。しかも、各軸支孔３１は、軸受片部２７の表側に位置する部位を大径部３２とし、該大径部３２の奥底に形成される掛止面３４を介して連続してさらに奥方向へと貫通する部位を小径部３５とすることにより、支軸材４２の挿入が自在となって形成されている。また、各大径部３２は、その周縁部３３の上縁側に直線部３３ａを設けた略Ｄ字状を呈して形成されている。
【００２３】
支軸材４２は、一方の側である背面側に位置する軸止孔３１の図示しない大径部の掛止面にその頭部４４を掛止させて他方の側である前面側に位置する軸受孔３１の側にねじりコイルばね６２を介装させた状態でその先端部４８が到達する軸本体部４３と、他方の側である前面側に位置する軸支孔３１の大径部３２の掛止面３４にその頭部４９を掛止させて軸本体部４３の先端部４８に嵌着される蓋体部４９とで形成されている。
【００２４】
このうち、軸本体部４３は、頭部４４と、該頭部４４から所定長が付与されて延設された軸部４７とで形成されている。この場合、頭部４４は、軸支孔３１の大径部３２の掛止面３４に掛止されるフランジ部４４ａと、該フランジ部４４ａの上面側に短寸の円柱状に突設された突出部４４ｂとで形成されている。また、該突出部４４ｂの頂面における略半円部分には、先端縁４６ａ側が最も肉厚の薄い前傾斜面４６が形成されている。さらに、フランジ部４４ａには、大径部３２の直線部３３ａに対応合致させるための切除部４５が、突出部４４ｂの前傾斜面４６とは反対側の位置に水平方向に直線状となって形成されており、これら直線部３３ａと切除部４５とで頭部４４を正しく位置決めするための位置固定部３７を形成することができるようになっている。
【００２５】
軸本体部４３における軸部４７は、軸支孔３１内に位置する部位を軸支孔３１の内径と略同等とした太径部４７ａと、その余の細径部ｂとで形成されている。
【００２６】
一方、蓋体部４９は、頭部５０と、軸部４７の太径部４７ａと同径が付与されて頭部５０側から短寸に延設された短軸部５３とで形成されている。この場合、頭部５０は、軸支孔３１の大径部３２の掛止面３４に掛止されるフランジ部５０ａと、該フランジ部５０ａの上面側に短寸の円柱状に突設された突出部５０ｂとで形成されている。また、該突出部５０ｂの頂面における略半円部分には、先端縁５２ａ側が最も肉厚の薄い前傾斜面５２が形成されている。さらに、フランジ部５０ａには、大径部３２の直線部３３ａに対応合致させるための切除部５１が形成されており、該切除部５１と大径部３２の直線部３３ａとで位置固定部３８を形成することができるようになっている。
【００２７】
蓋体部４９における短軸部５３には、軸本体部４３における軸部４７の先端部４８である細径部４７ｂへの嵌着を自在とした嵌合穴５４が設けられている。
【００２８】
また、他側クリップ片２２の天板部２５の内側面の適位置には、図４（ｂ）に示されているように、そのコイル部６３を介して支軸材４２に介装させた際にねじりコイルバネ６２の他方の掛止腕部６５を掛合する掛止突起３６が設けられている。
【００２９】
このようにして支軸材４２とねじりコイルばね６２とが配設された他側クリップ片２２は、軸本体部４３の頭部４４に設けた前傾斜面４６と蓋体部４９の頭部５０に設けた前傾斜面５２とが位置する側から、一側クリップ片１２が備える一対の軸受片部１７，１７の内面側に沿わせて導入し、コイルばね６２の一方の掛止腕部６４を所定位置に掛止させつつ、軸本体部４３の頭部４４と蓋体部４９の頭部５０とを対応する軸受孔１７ａに各別に嵌着させて一側クリップ片１２と一体化させることにより、図２に示すクリップ１１が形成される。
【００３０】
次に、本発明に係るクリップ１１の組立ての手順を図１と図３とを参酌しながら説明する。まず、一方の掛止腕部６４を下方に、他方の掛止腕部６５を上方に位置させたねじりコイルばね６２のコイル部６３を他側クリップ片２２の空間部２２ａ内に図３に２点鎖線として示されている位置関係のもとで配置する。
【００３１】
次いで、他側クリップ片２２には、その一方（図３では右側）の軸受片部２７の軸支孔３１に対し、外側から軸本体部４３の軸部４７にあって先端部４８側に位置している細径部４７ｂを挿入し、ねじりコイルばね６２のコイル部６３を挿通させた上で他方（図３では左側）の軸受片部２７の軸支孔３１内へと到達させる。
【００３２】
しかも、このような軸本体部４３の挿入操作は、軸支孔３１の掛止面３４に頭部４４におけるフランジ部４４ａが掛止された時点で終了する。また、同フランジ部４４ａは、軸支孔３１の大径部３２に設けられている直線部３３ａと合致する切除部４５を備えているので、いちいちその方向を確認することなく相互間で図４（ｂ）に示すように位置固定部３７を形成しながら位置決めされた状態のもとで軸本体部４３を挿入することができる。
【００３３】
このようにして軸本体部４３の挿入操作を終えた後は、図３では左側に位置している軸受片部２７の軸支孔３１に対しその外側から蓋体部４９の短軸部５３を挿入し、軸本体部４３の軸部４７の細径部４７ｂにその嵌合穴５４を嵌着して支軸材４２として一体化させる。
【００３４】
しかも、このような蓋体部４９の挿入操作は、軸支孔３１の掛止面３４に頭部５０におけるフランジ部５０ａが掛止された時点で終了する。また、同フランジ部５０ａは、軸支孔３１の大径部３２に設けられている直線部３３ａと合致する切除部５１を備えているので、軸本体部４３の側と同様にいちいちその方向を確認することなく相互間で図４（ａ），（ｂ）に示されているように位置固定部３８を形成しながら、正しく位置決めされた状態で蓋体部４９を嵌着することができる。
【００３５】
その結果、他側クリップ片２２の側は、図１に示すようにその空間部２２ａ内に支軸部４２を介してねじりコイルばね６２を介装させた状態とすることができるので、単に一側クリップ片１２の側に差し込むことにより一体化させてクリップ１１を形成することができる。
【００３６】
すなわち、他側クリップ片２２の側は、一対の軸受片部２７，２７の外側面に軸本体部４３の頭部４４を構成している突出部４４ｂと、蓋体部４９の頭部５０を構成している突出部５０ｂとが、図１に示すようにそれぞれの前傾斜面４６，５２をその先端縁４６ａ，５２ａが下方を向く位置関係で、一側クリップ片１２の上方に配置することができる。
【００３７】
一側クリップ片１２と他側クリップ片２２との組み立て作業は、このような配置関係におかれた一側クリップ片１２が備える一対の軸受片部１７，１７相互間に確保される空間部１２ａ内に、他側クリップ片２２が備える一対の軸受片部２７，２７をその上方から差し込み、ねじりコイルばね６２の一方の掛止腕部６４を所定の位置に配置しながら、軸受片部１７が有する各軸受孔１７ａに軸本体部４３の突出部４４ｂと、蓋体部４９の突出部５０ｂとを各別に嵌合させることにより行うことができる。
【００３８】
しかも、軸本体部４３の突出部４４ｂと蓋体部４９の突出部５０ｂとは、前傾斜面４６，５２を有しているので、その差し込み作業もこれら前傾斜面４６，５２に支援され、かつ、少なくとも一対の軸受片部１７，１７が撓み変形可能となっていることとも相俟って、位置合わせ作業を経ることなく極めて円滑に行うことができるので、その組み立て作業も強い力をかけることなく迅速、かつ、容易に行うことができる。
【００３９】
したがって、一側クリップ片１１と他側クリップ片２２とは、その常態において、一側咬持部１３の側に対して他側咬持部２３の側を常閉方向へと圧接させた状態のもとでクリップ１１を組み立てることができる。なお、クリップ１１は、操作レバー部２４をねじりコイルばね６２の付勢力に抗して押し下げることにより、図２に示すように他側咬持部２３を強制的に開口させることができる。
【００４０】
以上は、本発明を図示例に即して説明したものであり、その具体的な実施形態はこれに限定されるものではない。例えば、本発明が適用されるクリップは、図示例のような鰐口クリップのほか、洗濯ばさみなどのような日常的に使用される各種の用途に供される構造を備えたものであってもよい。また、図示例では常閉状態となった構造のクリップが示されているが、ねじりコイルばねの配置により常開状態にした構造のクリップであってもよい。さらに、他側クリップ片２２が備える一対の軸受片部２７，２７は、撓み変形の可否を問わない。
【００４１】
また、軸本体部４３の突出部４４ｂと蓋体部４９の突出部５０ｂとのそれぞれには、必要により前傾斜面４６，５２を設けないでおくこともできる。さらに、フランジ部４４ａの切除部４５と、これに合致する一方の大径部３２の直線部３３ａとを不要とし、同様に、フランジ部５０ａの切除部５１と、これに合致する他方の大径部３２の直線部３３ａとを不要とすることもできる。さらにまた、位置固定部３７，３８の位置は、図示例のように周縁部３３の上縁側に切除部４５，５１と直線部３３ａ，３３ａとを設けることができるほか、その他の適宜の部位に設けることもできる。また、図示例では、一方のクリップ片が固定側で他方のクリップ片が可動側となったクリップが示されているが、双方のクリップ片を可動としたクリップであってもよい。
【００４２】
さらに、位置固定部３７，３８は、例えば、大径部３２の内周面に凸部を形成し、フランジ部４４ａ，５０ａの外周面に凹部を形成（この逆も可）して相互に嵌合させて形成するようにしてもよい。
【００４３】
【発明の効果】
以上述べたように本発明によれば、他側クリップ片には、予めねじりコイルばねを介装させた支軸材を軸支させ、該軸支材を構成している軸本体部の頭部と蓋本体部の頭部とを一側クリップ片の軸受孔に各別に嵌合させることで、該一側クリップ片と他側クリップ片とを一体化して簡単にクリップを組み立てることができる。
【００４４】
したがって、組立て時にねじりコイルばねの弾性反発力を力で押さえ付けておく必要がなくなり、それだけ組み立て工数を減らして組立作業の効率化を実現することができる。
【００４５】
また、支軸材を構成する軸本体部の頭部と蓋体部の頭部とに前傾斜面を設けたり、軸本体部の頭部と該頭部側が掛止される一方の軸支孔の大径部との間、および蓋体部の頭部と該頭部側が掛止される他方の軸支孔の大径部との間のそれぞれに位置固定部を設けておく場合には、一側クリップ片に対する他側クリップ片の組み付け作業をより円滑に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a shaft support structure suitable for various types of clips including, for example, a hook clip that can be freely attached to and detached from a connection terminal of a measuring device and electrically connected thereto.
[0002]
[Prior art]
5 is an exploded perspective view showing an example of a conventional shed clip, and FIG. 6 is an overall perspective view showing an assembled state of the example shown in FIG. According to these drawings, the shed clip 111 includes a fixed side clip piece 112, a movable side clip piece 122 disposed on the upper side so as to face the fixed side clip piece 112, and the fixed side clip piece 112, The movable side clip piece 122 is integrally supported by a synthetic resin material supporting shaft part 132 having a torsion coil spring 142 interposed therebetween, thereby forming the whole.
[0003]
For this reason, the movable side holding portion 123 provided on the distal end side of the movable side clip piece 122 is a fixed side clip piece 112 provided on the proximal end side with a cable guide tube portion 115 into which one end side of a connection cable (not shown) is introduced. The stationary side holding portion 113 provided on the distal end side is in pressure contact with the urging force of the torsion coil spring 142 and is in a normally closed state.
[0004]
Further, the movable side clip piece 122 pushes down the operation lever 125 provided on the base end side thereof, thereby to move the movable side holding portion 123 against the urging force of the torsion coil spring 142 and to fix the fixed side clip piece 112 to the fixed side. It can be forcibly separated from the biting part 113.
[0005]
Furthermore, saw-toothed metal pieces 114 and 124 that are meshed with each other when they are closed are opposed to each other on the facing side of the fixed side holding portion 113 and the movable side holding portion 123. Although not shown, the serrated metal piece 114 included in the fixed side holding portion 113 is one end of a connection cable introduced into the cable guide tube portion 115 via a conductive material made of a conductive metal plate or the like. It can be electrically connected to the side.
[0006]
By the way, the shed clip 111 shown in FIG. 5 is provided with a pair of bearing pieces 116 and 116 provided in the fixed clip piece 112 and a pair of bearing pieces 126 and 126 provided in the movable clip piece 123, respectively. The shaft support holes 117 and 127 are connected to each other through a support shaft part 132 in communication.
[0007]
In this case, the shaft support structure is configured such that the bearing piece portions 126 of the movable side clip piece 123 are arranged inside the bearing piece portions 116 of the fixed side clip piece 112 so that the respective shaft support holes 117 and 127 communicate with each other. After that, the shaft support holes 117 and 127 are inserted to the position where the flange 133 provided at the base end of the support shaft portion 132 is hooked, and the tip portion 134 protruding from the opposite side is heated, ultrasonic, etc. The fixing portion 135 is formed by caulking so as not to come off from the bearing piece portion 116 of the corresponding fixed side clip piece 112 by an appropriate heating method or by welding to the outside of the bearing piece portion 116.
[0008]
[Problems to be solved by the invention]
However, in the case of the shaft support structure shown in FIG. 5, first, the shaft support hole 117 provided in the bearing piece portion 116 of the fixed clip piece 113 and the shaft support hole 127 provided in the bearing piece portion 126 of the movable clip piece 123. Must be properly positioned and arranged so as to be in a positional relationship in which they communicate with each other.
