【発明の属する技術分野】
トリムボードに係合するクリップ及びこのクリップを介して、ボディパネルにトリムボードを取付けるトリムボード取付構造に関する。
【０００２】
【従来の技術】
車両のボディパネルには、クリップを介してトリムボードが取り付けられている。例えば、特開平１０−１３１９２６号公報では、クリップが、トリムボードに固定可能な第１連結部と、ボディパネルに係合可能な第２連結部と、を備えている。
【０００３】
この第１連結部及び第２連結部の何れか一方には、軸受凹部が設けられ、第１連結部及び第２連結部の何れか他方には、軸受凹部に係合可能な球状軸部が設けられている。この軸受凹部と球状軸部との係合によって、第１連結部と第２連結部とが連結されている。
【０００４】
ところで、第１連結部の一端面には、溶着しろが設けられており、この溶着しろを溶融させて第１連結部をトリムボードに固定させる。一方、第２連結部には複数の弾性片及び差込み部が設けられており、ボディパネルに形成された挿通穴に差込み部を挿通させ、弾性片を挿通穴の周縁部に係合させて第２連結部をボディパネルに固定させる。これにより、クリップを介して、ボディパネルにトリムボードが固定される。
【０００５】
ここでは、球状軸部は軸受凹部内で回転自在となるため、ボディパネルとトリムボードとの位置ズレによる寸法誤差を吸収できるが、第１連結部のトリムボードへの固定方法が、第１連結部に溶融しろを設けこの溶融しろを溶融させて第１連結部をトリムボードへ固定させる方法であるため、作業が面倒であり、コストアップとなってしまう。
【０００６】
一方、特開平１０−１７６７０５号公報では、トリムボードには環状ボスが設けられており、この環状ボスの先端内面側には、環状ボスの周方向に沿って係止溝が形成され、クリップを構成する第１クリップが、この環状ボスに固定可能となっている。
【０００７】
また、第１クリップにはボディパネルに固定される第２クリップが固定可能となっており、ボディパネルに固定された第２クリップを環状ボスに固定された第１クリップに固定させることで、クリップを介してボディパネルにトリムボードが固定されることとなる。
【０００８】
ここで、第１クリップはホルダーと一体成形されており、このホルダーには一対の円弧リブが立設している。この円弧リブの先端部には、係止爪が形成されており、環状ボスに設けられた係止溝に係合して、第１クリップが環状ボスに固定される。
【０００９】
しかしながら、このように、単に係止溝に係止爪を係止させただけの固定方法では、車両の走行時の振動等により、係止爪が係止溝から外れる恐れがある。

【発明が解決しようとする課題】
本発明は上記事実を考慮し、作業性が良く、トリムボードから外れ難いクリップ及びこのクリップを利用したトリムボード取付構造を安価で提供することを目的とする。
【００１２】
【課題を解決するための手段】
請求項１に記載の発明は、ボディパネルに取付けるトリムボードを成形する金型の離型方向に沿って離型すると共に、前記トリムボードから突設し拡幅可能な第１取付座に係合可能なクリップにおいて、前記クリップが、前記第１取付座を拡幅させて第１取付座へ内挿可能な第１係合部と、前記第１係合部から所定の距離を置いて配置され、第１係合部が前記第１取付座へ内挿された状態で第１取付座の外側に位置して第１取付座の拡幅を防止する拡幅防止リブと、前記第１係合部の反対側に位置し前記ボディパネルに面接可能な傘部と、前記傘部中央から立設し前記ボディパネルに形成された穴部へ挿通可能な挿通部と、前記挿通部に挟幅可能に設けられ挿通部を前記穴部へ挿通させた状態で前記傘部との間で前記ボディパネルの内縁部を挟持可能な爪部と、で構成されたことを特徴としている。
【００１３】
請求項１に記載の発明では、クリップに第１係合部を設けており、この第１係合部によって、第１取付座を拡幅して、第１係合部を第１取付座へ内挿し、トリムボードにクリップを係合させるため、作業性が良い。
【００１４】
また、クリップに拡幅防止リブを設け、第１係合部が第１取付座へ内挿された状態で、第１取付座の外側に位置して第１取付座の拡幅を防止することで、第１係合部が第１取付座から抜けないようにすることができる。
【００１５】
一方、第１係合部の反対側に、ボディパネルに面接可能な傘部を設けており、この傘部中央からは挿通部を立設させ、ボディパネルに形成された穴部へ挿通可能としている。
【００１６】
挿通部には、挟幅可能な爪部を設けており、挿通部を穴部へ挿通させた状態で、爪部と傘部との間でボディパネルの内縁部を挟持させる。これにより、クリップを介してボディパネルにトリムボードを固定させることができる。
【００１７】
ここで、第１取付座を略球状凹部とし、第１係合部を略球体とすることで、第１取付座に対してクリップを若干揺動させることができる。このため、トリムボードとボディパネルとの間の位置ズレを吸収させることができる。
【００１８】
請求項２に記載の発明は、クリップを介して、ボディパネルにトリムボードを取付けるトリムボード取付構造において、前記トリムボードを成形する金型の離型方向に沿って離型すると共に、拡幅可能な第１取付座がトリムボードから突設し、前記クリップが、前記第１取付座を拡幅させて第１取付座へ内挿可能な第１係合部と、前記第１係合部から所定の距離を置いて配置され、第１係合部が前記第１取付座へ内挿された状態で第１取付座の外側に位置して第１取付座の拡幅を防止する拡幅防止リブと、前記第１係合部の反対側に位置し前記ボディパネルに面接可能な傘部と、前記傘部中央から立設し前記ボディパネルに形成された穴部へ挿通可能な挿通部と、前記挿通部に挟幅可能に設けられ、挿通部を前記穴部へ挿通させた状態で前記傘部との間で前記ボディパネルの内縁部を挟持可能な爪部と、で構成されたことを特徴としている。
【００１９】
請求項２に記載の発明では、クリップを介して、ボディパネルにトリムボードを取付けている。ここで、トリムボードからは第１取付座を突設させており、この第１取付座を、トリムボードを成形する金型の離型方向に沿って離型可能としている。
【００２０】
例えば、トリムボードの金型の離型方向に対して直交する方向に、無理抜き不可能なアンダーカット部（アンダーカット部の張出量が大きい）を設けた場合、このアンダーカット部を形成させるためには、アンダーカット部において、金型構造上、スライドコア或いは傾斜ピンを設ける必要が生じる。このため、金型構造が複雑となり、金型費用が高くなってしまう。
【００２１】
しかし、トリムボードに突設させる第１取付座を、トリムボードの金型の離型方向に沿って離型可能（無理抜き可能なアンダーカット部も含む）に形成させることで、トリムボードの金型にスライドコア等を設ける必要がなくなるので、金型構造が簡易になり、大幅なコストダウンを図ることができる。
【００２２】
請求項３に記載の発明では、拡幅防止リブを環状とし、拡幅防止リブと第１係合部とを薄肉部で連設して、第１係合部を第１取付座へ内挿するとき、薄肉部を切断して、拡幅防止リブを第１係合部から分離させる。
【００２３】
例えば、第１取付座の高さを拡幅防止リブの高さよりも高くした場合、第１係合部を第１取付座へ内挿した状態で、第１係合部から分離された拡幅防止リブを第１取付座の基部側へ移動させると、第１取付座の先端側はフリーとなる。
【００２４】
第１取付座の拡幅量は、第１取付座の基部よりも先端の方が大きいため、この状態では、第１取付座は拡幅可能となり、第１係合部を取り外すことができる。従って、請求項３に記載の発明では、トリムボードに対するクリップの脱着が可能となる。
【００２５】
また、拡幅防止リブを環状とすることで、第１取付座の先端側の全周を覆うため、第１係合部が第１取付座からさらに抜け難くなり、第１取付座に対する第１係合部の抜け強度を高めることができる。
【００２６】
このように、第１取付座に対する第１係合部の抜け強度を高めることで、第１取付座の肉厚を薄くすることが可能となる。このため、第１取付座の裏面側に生じるひけを小さくすることができる。
【００２７】
また、第１取付座の肉厚を薄くすることで、第１取付座の先端側に設けられた球状凹部の深さを浅くすることができる。従って、アンダーカット部を小さくすることができるので、トリムボードが金型から離型し易くなり、トリムボードの表面に、金型に配設されたエジェクターピンによる白化が生じたり、また、トリムボードが変形したりする恐れはない。
【００２８】
請求項４に記載の発明は、クリップをリテーナ部材に係合させ、前記リテーナ部材をトリムボードに固定すると共に、ボディパネルに前記クリップを装着して、前記ボディパネルに前記トリムボードを取付けるトリムボード取付構造において、前記トリムボードを成形する金型の離型方向に沿って離型する第２取付座が前記トリムボードから突設し、前記クリップが、前記ボディパネルに面接可能な傘部と、前記傘部中央から立設し前記ボディパネルに形成された穴部へ挿通可能な挿通部と、前記挿通部に挟幅可能に設けられ前記傘部との間で前記ボディパネルの内縁部を挟持可能な爪部と、前記傘部に重ねて設けられた第１挟持板と、前記第１挟持板から立設する軸部と、前記軸部の端部に前記第１挟持板と平行に設けられた第２挟持板と、で構成され、前記リテーナ部材が、前記第２取付座が係合可能な第２係合部と、前記第２係合部に連設され、前記第２係合部の前記第２取付座への係合方向と直交する方向に沿って前記軸部が侵入可能な切欠き部が形成されて、軸部が前記切欠き部内を侵入した状態で、前記第１挟持板と前記第２挟持板が前記切欠き部の周縁部を挟持して前記クリップを係合する装着部と、で構成されたことを特徴としている。
【００２９】
請求項４に記載の発明では、クリップをリテーナ部材に係合させ、リテーナ部材をトリムボードに固定すると共に、ボディパネルにクリップを装着して、ボディパネルにトリムボードを取付けている。ここで、トリムボードからは第２取付座を突設させており、この第２取付座を、トリムボードを成形する金型の離型方向に沿って離型可能としている。
【００３０】
一方、クリップにはボディパネルに面接可能な傘部を設けており、この傘部中央からは挿通部を立設させ、ボディパネルに形成された穴部へ挿通可能としている。この挿通部には、爪部を挟幅可能に設けており、挿通部を穴部へ挿通させた状態で、爪部と傘部との間でボディパネルの内縁部を挟持させる。
【００３１】
ここで、傘部に重ねて第１挟持板を設けており、第１挟持板からは軸部が立設している。この軸部の端部に、第１挟持板と平行に第２挟持板を設けている。一方、リテーナ部材には、第２取付座が係合可能な第２係合部を設けており、第２係合部を第２取付座に係合させてリテーナ部材をトリムボードに固定させることができる。
【００３２】
また、リテーナ部材には、クリップが装着可能な装着部を設けており、この装着部には、第２係合部の第２取付座への係合方向と直交する方向に沿って、クリップに形成された軸部が侵入可能な切欠き部を形成させている。
【００３３】
この切欠き部内へ第１挟持板から立設した軸部を侵入させた状態で、クリップの第１挟持板と第２挟持板とで切欠き部の周縁部を挟持させる。これにより、クリップが装着部に装着される。
【００３４】
このように、トリムボードに係合して固定させると共に、クリップが装着可能なリテーナ部材を用いることで、部品点数は増えてしまうが、複雑な形状でも金型構造を単純化させることができるため、金型加工費の削減を図ることができる。
【００３５】
請求項５に記載の発明では、第２取付座が一対の板部材であり、第２係合部が包囲リブである。この包囲リブの表面には、板部材に食付き可能な突起部を突設しており、包囲リブが板部材の表面を包囲した状態で突起部を板部材へ押し付けている。
【００３６】
このように、第２取付座を板部材とし、第２係合部に突起部を設けてこの突起部を板部材の表面に食付かせることで、トリムボードにクリップを取付けることが可能となり、トリムボードには無理抜き可能なアンダーカット部を設ける必要はなくなる。このため、トリムボードの金型の離型性が向上する。また、単純な構成であるため、金型製作期間を短縮させることができ、金型費用の削減を図ることができる。
【００３７】
請求項６に記載の発明では、包囲リブの板部材への係合方向に沿って板部材の表面に係合リブを形成し、また、係合リブに対して直交する方向に沿って突起部を設けている。
【００３８】
このため、突起部が係合リブに食付くこととなり、板部材に対して食付き易くなる。また、突起部が係合リブに対して直交した状態で食付くことで、板部材に対する食付き性が良くなる。
【００３９】
請求項７に記載の発明では、第２取付座を円筒状のボスとし、第２係合部をボスにネジ部を形成させるネジ部材としている。
【００４０】
このように、第２取付座を単に円筒状のボスとすることで、請求項６に記載の発明と比較してさらに、金型製作期間を短縮させることができ、金型費用の削減を図ることができる。また、ボスにネジ部材をねじ込み、ネジ部を形成しながら、ボスに第２係合部を係合させるため、リテーナ部材がトリムボードにしっかり固定される。
【００４１】
【発明の実施の形態】
本発明の第１の実施形態に係るクリップ及びこのクリップを利用したトリムボード取付構造について説明する。
【００４２】
図３に示すように、車両のボディパネル１０には、クリップ１２を介してトリムボード１４が固定可能となっている。トリムボード１４には略円筒状の取付座１６（第１取付座）が立設しており、取付座１６の先端側の内面には、取付座１６の周方向に沿って球状凹部１８が形成されている。また、取付座１６の先端部からは、取付座１６の軸方向に沿って一対の逆Ｕ字状の切欠き部２０が形成されている。
【００４３】
ところで、トリムボード１４は金型（図示省略）で成形されており、金型のパーティングラインをトリムボード１４の表面或いは裏面としている。ここで、取付座１６はトリムボード１４の裏面に対して垂直に設けられており、金型の離型方向に沿って形成されている。
【００４４】
このため、取付座１６に形成された球状凹部１８は、金型の離型方向に対して直交する方向、いわゆるアンダーカット部に相当するが、トリムボード１４の材料に応じて、球状凹部１８の深さ及び幅を金型の無理抜き可能な寸法に設定している。
【００４５】
一方、クリップ１２には、略環状の台座２２が備えられており、台座２２の内縁部からは、環状リブ２４が立設し、環状リブ２４の端部には、中空状のボール２６（第１係合部）が一体に設けられている。
【００４６】
このボール２６の外径寸法は、取付座１６の内径寸法よりも若干大きくなっており、また、取付座１６に形成された球状凹部１８に面接可能な大きさとなっている。また、ボール２６の外側には、台座２２の上面から、台座２２の同心円上に一対の円弧状の拡幅防止リブ２８がボール２６を間に置いて立設している。
【００４７】
この拡幅防止リブ２８同士の離間距離は、取付座１６の外径寸法よりも若干大きくなっており、取付座１６へ外挿可能となっている。また、拡幅防止リブ２８はクリップ１２の正面視において、拡幅防止リブ２８からボール２６が約半分露出する高さとなっており、先端部内面には、面取り部３０が形成されている。
【００４８】
一方、台座２２の下面側からは、斜め下方へ向かって環状の傘部３２が張り出している。この傘部３２はボディパネル１０に形成された円孔部１０Ａの周縁部に面接可能な大きさとなっている。
【００４９】
また、傘部３２の中央部からは、先端に先細部３４Ａが形成された略円筒状の挿通部３４が垂下している。この挿通部３４には、下方を開口とした略コ字状の一対の切り込み部３６が切り込まれており、切り込み部３６の内側には、断面が略三角形状を成す爪部３８が挿通部３４の外周面から張出している。
【００５０】
この爪部３８を押圧すると、内側に撓み、挟幅（爪部３８同士の離間距離が短い）可能となっている。ここで、爪部３８は、ボディパネル１０の円孔部１０Ａの内径寸法よりも拡幅した状態で形成されており、爪部３８が挟幅された状態で、挿通部３４がボディパネル１０の円孔部１０Ａを通過可能となる。
【００５１】
次に、トリムボードの取付方法について説明する。
【００５２】
図２（Ａ）に示すように、取付座１６の切欠き部２０の下方に、クリップ１２の拡幅防止リブ２８が配置されないようにしてクリップ１２を位置決めし、取付座１６内へクリップ１２のボール２６を挿入させる。
【００５３】
ボール２６の外径寸法は、取付座１６の内径寸法よりも若干大きくなっているため、ボール２６が取付座１６の先端部に当接した時点で、ボール２６は移動規制される。
【００５４】
このため、図２（Ｂ）に示すように、ボール２６を取付座１６内へ圧入する。これにより、取付座１６に形成された一対の切欠き部２０によって取付座１６の先端側が拡径し、ボール２６を取付座１６内へ挿入させることができる。
【００５５】
このとき、拡幅防止リブ２８の先端側が、取付座１６の先端部に当接するが、ボール２６の挿入と共に、拡幅防止リブ２８に形成された面取り部３０によって、取付座１６の先端部が縮径する方向へガイドされる。
【００５６】
そして、図２（Ｃ）に示すように、ボール２６の外面に沿って、取付座１６がボール２６と拡幅防止リブ２８の間に配置され、取付座１６の先端側内面に形成された球状凹部１８にボール２６の外面が面接した状態で、クリップ１２は係合し、移動規制された状態で、トリムボード１４にクリップ１２が固定される。
【００５７】
次に、図３に示すように、ボディパネル１０に形成された円孔部１０Ａ内へ、クリップ１２に形成された挿通部３４を挿通させる。挿通部３４に設けられた爪部３８は、ボディパネル１０の円孔部１０Ａの内径寸法よりも拡幅した状態で形成されているため、円孔部１０Ａ内へ挿通部３４を挿通させると、円孔部１０Ａの内縁部に爪部３８が当接する。
【００５８】
この状態で、クリップ１２をボディパネル１０側へ押圧すると、挿通部３４の移動と共に、爪部３８が縮径して円孔部１０Ａを通過する。このように、爪部３８が円孔部１０Ａを通過すると、爪部３８が復元して、傘部３２と爪部３８との間で円孔部１０Ａの周縁部が挟持される。これにより、クリップ１２を介して、ボディパネル１０にトリムボード１４が取り付けられる。
【００５９】
なお、ここでは、トリムボード１４にクリップ１２を係合させた後、ボディパネル１０にクリップ１２を装着させたが、ボディパネル１０にクリップ１２を装着した後、トリムボード１４をクリップ１２に係合させても良い。
【００６０】
次に、本発明の第１の実施形態に係るクリップ及びこのクリップを利用したトリムボード取付構造の作用について説明する。
【００６１】
トリムボード１４の取付座１６をトリムボード１４の裏面に対して垂直に設け、金型の離型方向に沿って形成することで、トリムボード１４の金型にスライドコア等を設ける必要がないため、金型構造が簡易になり、大幅なコストダウンを図ることができる。
【００６２】
ここで、取付座１６に形成された球状凹部１８は、いわゆるアンダーカット部に相当するが、トリムボード１４の材料に応じて、球状凹部１８の深さ及び幅を金型の無理抜き可能な寸法に設定することによって、スライドコア或いは傾斜ピンに因らずに球状凹部１８を離型させることができる。
【００６３】
また、クリップ１２にボール２６を設け、このボール２６によって、取付座１６を拡幅して、取付座１６へ内挿すると共に、ボール２６の外側に拡幅防止リブ２８を設け、ボール２６が取付座１６へ内挿された状態で取付座１６の外側に配置して取付座１６が拡幅しないようにすることで、取付座１６にクリップ１２を容易に係合させることができると共に、クリップ１２が取付座１６から抜けないようにすることができる。
【００６４】
さらに、取付座１６に球状凹部１８を設け、この球状凹部１８にボール２６を係合させることで、取付座１６に対してクリップ１２を若干揺動させることができるため、トリムボード１４とボディパネル１０との間の位置ズレを吸収させることができる。
【００６５】
また、ボール２６を中空状とすることで、クリップ１２の成形後にボール２６の表面にひけが生じないようにしている。これにより、ボール２６の寸法のバラツキを防止することができる。
【００６６】
なお、ここでは、ボール２６を用いて取付座１６を拡幅し、拡幅防止リブ２８によって取付座１６の拡幅を防止したが、取付座を拡幅させてクリップを係合させた後、取付座の拡幅を防止することができれば良いため、これに限るものではない。
【００６７】
次に、本発明の第２の実施形態に係るクリップ及びこのクリップを利用したトリムボード取付構造について説明する。なお、第１の実施形態と略同一の内容については説明を割愛する。
【００６８】
図４及び図５（Ａ）に示すように、クリップ３９に備えられたボール２６の外面からは、台座２２に対して平行に、かつ、ボール２６を上下二分する位置において、９０度間隔で薄肉片４０が張り出している。この薄肉片４０は、先端側に行くに従って先細となっており、薄肉片４０の先端部には、環状リブ４１の下端部が連設し、ボール２６の上半分を覆っている。
【００６９】
環状リブ４１は、ボール２６に対して上下方向に移動させると、薄肉片４０が破断するようになっており、環状リブ４１の長さは、取付座１６の基部から球状凹部１８までの長さよりも短くなっている。
【００７０】
次に、トリムボードの取付方法について説明する。
【００７１】
図５（Ａ）、（Ｂ）に示すように、環状リブ４１をボール２６に対して上下方向へ移動させて薄肉片４０を破断させ、環状リブ４１をボール２６から分離させる。環状リブ４１をボール２６の外側に配置させた状態で、図５（Ｃ）に示すように、ボール２６を取付座１６内へ圧入する。
【００７２】
取付座１６に形成された切欠き部２０によって取付座１６の先端側が拡径して、ボール２６が取付座１６内へ挿入される。このとき、環状リブ４１の先端部に形成された面取り部４１Ａに取付座１６の先端部が当接することによって、環状リブ４１がボール２６の同心円状に配置されると共に、取付座１６の先端部が縮径する方向へガイドされる。
【００７３】
そして、図５（Ｄ）に示すように、ボール２６の外面に沿って、取付座１６がボール２６と環状リブ４１の間に配置され、取付座１６の先端側内面に形成された球状凹部１８にボール２６の外面が面接した状態で、クリップ３９は係合し、移動規制された状態で、トリムボード１４にクリップ３９が固定される。
【００７４】
次に、本発明の第２の実施形態に係るクリップ及びこのクリップを利用したトリムボード取付構造の作用について説明する。
【００７５】
ここでは、ボール２６と環状リブ４１を連設させる薄肉片４０を破断させてボール２６から分離させると共に、環状リブ４１の長さを、取付座１６の基部から球状凹部１８までの長さよりも短くしている。
【００７６】
これにより、図６（Ａ）、（Ｂ）に示すように、取付座１６にクリップ１２を固定させた後、環状リブ４１を取付座１６の上方へ移動させることで、取付座１６の先端側をフリーにすることができる。このため、図６（Ｃ）に示すように、取付座１６からクリップ１２を取り外すことができ、取付座１６に対するクリップ１２の脱着が可能となる。
【００７７】
一方、取付座１６にクリップ１２が固定された状態において、環状リブ４１によって取付座１６の先端側の全周を覆うため、クリップ３９が取付座１６からさらに抜け難くなり、取付座１６に対するクリップ３９の抜け強度を高めることができる。
【００７８】
このように、取付座１６に対するクリップ３９の抜け強度を高めることで、取付座１６の肉厚を薄くすることが可能となる。このため、取付座１６の裏面側に生じるひけを小さくすることができる。
【００７９】
また、取付座１６の肉厚を薄くすることで、取付座１６の先端側に設けられた球状凹部１８の深さを浅くすることができる。従って、アンダーカット部を小さくすることができるので、トリムボード１４が金型から離型し易くなり、トリムボード１４の表面に、金型に配設されたエジェクターピンによる白化が生じたり、また、トリムボード１４が変形したりする恐れは少ない。
【００８０】
次に、本発明の第３の実施形態に係るクリップ及びこのクリップを利用したトリムボード取付構造について説明する。なお、第１の実施形態と略同一の内容については説明を割愛する。
【００８１】
図７に示すように、ここでは、トリムボード４２に固定可能なリテーナ部材４４を用い、このリテーナ部材４４にクリップ４６を係合させている。
【００８２】
トリムボード４２には一対の板部材４８が立設しており、先端には徐々に幅寸法が狭くなる挟幅部４８Ａが形成されている。また、板部材４８の表面及び裏面には、挟幅部４８Ａを除き、板部材４８が立設する方向に沿って複数の係合リブ５０が平行に突設されている。
【００８３】
一方、リテーナ部材４４は装着部５２と係合部５４とで構成されている。装着部５２は略直方体を成しており、装着部５２の上面には、係合部５４が連設されている。
【００８４】
ここで、係合部５４には、平面視にて略Ｓ字状に形成され板部材４８を包囲可能な立壁５６が立設しており、対面する壁面５６Ａ同士の間隔は、板部材４８の肉厚よりも若干離間している。
【００８５】
また、対面する壁面５６Ａからは、リテーナ部材４４のトリムボード４２への係合方向（矢印方向）に対して直交する方向に沿って突起部５８が突設されている。少なくともこの突起部５８は板部材４８よりも剛性の高い材料で形成されており、また、対面する突起部５８同士の先端部の離間距離は、一つの板部材４８に形成された係合リブ５０同士の先端部の離間距離よりも短くなっている。このため、板部材４８に係合部５４を係合させた状態で、突起部５８が係合リブ５０に食付くようになっている。
【００８６】
一方、装着部５２は中空状となっており、装着部５２の下面には、リテーナ部材４４のトリムボード４２への係合方向に対して直交する方向に沿って、下面中央部に渡って切欠き部６０が切り欠かれている。この切欠き部６０は、下面中央部を係合穴６０Ａ（後述する）とし、開口部６０Ｂ側の幅が広くなっており、係合穴６０Ａへの入口部６０Ｃは挟幅となっている。
【００８７】
ここで、装着部５２に装着されるクリップ４６について説明する。なお、クリップ１２と略同一の内容に関しては説明を割愛する。
【００８８】
図７及び図８（Ａ）に示すように、クリップ４６に備えられた傘部６２の上方には、傘部６２に重ねて挟持板６４が設けられている。この挟持板６４からは軸部６６が立設しており、軸部６６の端部には挟持板６４と平行に、所定の距離を置いて挟持板６８が設けられている。この挟持板６４、６８の外径寸法は、装着部５２の切欠き部６０の係合穴６０Ａの内径寸法よりも大きくなっている。
【００８９】
ところで、装着部５２の切欠き部６０には、クリップ４６の軸部６６が、切欠き部６０の切欠き方向に沿って侵入可能となっており、切欠き部６０の係合穴６０Ａの内径寸法は、軸部６６の外径寸法よりも若干大きくなっている。
【００９０】
また、切欠き部６０の入口部６０Ｃの幅寸法は、軸部６６の外径寸法よりも若干狭くなっており、切欠き部６０の開口部６０Ｂを通過した後、軸部６６は入口部６０Ｃで移動規制され、圧入によって軸部６６を係合穴６０Ａ内へ侵入させることができる。
【００９１】
一方、挟持板６４と挟持板６８の離間距離は、装着部５２の下面の板厚と略同一の長さとなっており、挟持板６４と挟持板６８とで装着部５２の下面を挟持可能となっている。
【００９２】
次に、トリムボードの取付方法について説明する。
【００９３】
まず、リテーナ部材４４の装着部５２に形成された切欠き部６０内へクリップ４６の軸部６６を侵入させる。このとき、装着部５２の下面は、挟持板６４と挟持板６８とで挟持された状態となっており、この状態のまま、切欠き部６０の係合穴６０Ａ側へ軸部６６を移動させる。
【００９４】
軸部６６が切欠き部６０の入口部６０Ｃに当接して移動規制されると、軸部６６を圧入し、係合穴６０Ａ内へ侵入させ、係合穴６０Ａの周縁部を、挟持板６４と挟持板６８とによって挟持させる。
【００９５】
ここで、係合穴６０Ａの内径寸法の方が、軸部６６の外径寸法よりも大きいため、軸部６６を係合穴６０Ａ内へ侵入させた状態で、リテーナ部材４４とクリップ４６との間には、若干のガタが設けられる。
【００９６】
次に、図８（Ａ）、（Ｂ）に示すように、リテーナ部材４４をトリムボード４２の板部材４８に係合させる。係合部５４の立壁５６の壁面５６Ａ間に板部材４８の挟幅部４８Ａが配置されるようにしてリテーナ部材４４を位置決めした後、リテーナ部材４４を板部材４８へ圧入する。これにより、突起部５８が係合リブ５０に食付きながら板部材４８の奥方へ移動し、リテーナ部材４４が板部材４８に固定される。
【００９７】
そして、ボディパネル１０に形成された円孔部１０Ａ内へ、クリップ４６に形成された挿通部３４を挿通して、傘部６２と爪部３８との間で円孔部１０Ａの周縁部を挟持させる。これにより、クリップ４６を介して、ボディパネル１０にトリムボード４２が取り付けられる。
【００９８】
次に、本発明の第３の実施形態に係るクリップ及びこのクリップを利用したトリムボード取付構造の作用について説明する。
【００９９】
図７に示すように、トリムボード４２に係合させる係合部５４と、クリップ４６が装着可能な装着部５２を備えたリテーナ部材４４を用いることで、部品点数は増えてしまうが、複雑な形状でも金型構造を単純化させることができるため、金型加工費の削減を図ることができる。
【０１００】
また、トリムボード４２に板部材４８を形成し、リテーナ部材４４の係合部５４に突起部５８を形成させ、この突起部５８を板部材４８に食付かせて、トリムボード４２にクリップ４６を固定させるようにすることで、トリムボード４２には無理抜き可能なアンダーカット部を設ける必要はなくなる。
【０１０１】
このため、トリムボード４２の金型の離型性が向上する。また、図１に示す球状凹部１８のようなアンダーカット部を形成しなくても良いため、金型製作期間を短縮させることができ、金型費用の削減を図ることができる。
【０１０２】
さらに、図７に示すように、係合部５４の板部材４８への係合方向（矢印方向）に沿って係合リブ５０を形成し、また、この係合リブ５０に対して直交する方向に沿って突起部５８を設けることで、板部材４８に対して突起部５８が食付き易くなる。また、突起部５８が係合リブ５０に対して直交した状態で食付くことで、板部材４８に対する食付き性が良くなる。
【０１０３】
また、係合穴６０Ａの内径寸法を軸部６６の外径寸法よりも大きくして、リテーナ部材４４とクリップ４６との間に、若干のガタを設けることで、トリムボード４２とボディパネル１０との間で僅かな位置ズレが生じた場合に、位置ズレ分の寸法吸収が可能となる。
【０１０４】
さらに、リテーナ部材４４の係合部５４を、板部材４８を包囲する略Ｓ字状に形成された立壁５６とすることで、板部材４８同士が拡幅することを防止することができ、突起部５８が係合リブ５０に食付いた状態を維持することができる。
【０１０５】
なお、リテーナ部材の係合部としては、トリムボードの金型の離型方向に沿って形成された取付座に係合して固定することができれば良いため、これに限るものではない。
【０１０６】
例えば、図９及び図１０（Ａ）に示すように、係合部としてトリムボード７０に円筒状のボス７２（第２取付座）を立設させる。一方、装着部５２の上面からはタッピングネジ７４を立設させ、図１０（Ｂ）に示すように、タッピングネジ７４をボス７２にねじ込んでトリムボード７０にリテーナ部材７６を係合させても良い。
【０１０７】
これにより、第２取付座の形状を簡単にすることができるため、金型製作期間をさらに短縮させることができ、金型費用の削減を図ることができる。また、ボス７２にタッピングネジ７４をねじ込み、雌ネジ部７２Ａを形成しながら、ボス７２にリテーナ部材７６を係合させるため、リテーナ部材７６がトリムボード７０にしっかり固定される。
【０１０８】
また、ここでは、装着部５２の上面からタッピングネジ７４を立設させたが、トリムボード７０のボス７２にリテーナ部材７６を係合させることができれば良いため、これに限るものではない。
【０１０９】
例えば、図１１（Ａ）に示すように、リテーナ部材７８の装着部８０の上面に、雌ネジ部８２Ａが形成された係合ボス８２を立設させても良い。この場合、図１１（Ｂ）に示すように、トリムボード８４のボス８６の外周面に雄ネジ８６Ａを形成しながら、ボス８６にリテーナ部材７８を係合させることとなる。
【０１１０】
【発明の効果】
本発明は上記構成としたので、請求項１に記載の発明では、第１係合部が第１取付座へ内挿された状態で、第１取付座の外側に位置して第１取付座の拡幅を防止することで、第１係合部が第１取付座から抜けないようにすることができる。また、第１取付座を略球状凹部とし、第１係合部を略球体とすることで、トリムボードとボディパネルとの間の位置ズレを吸収させることができる。
【０１１１】
請求項２に記載の発明では、トリムボードに突設させる第１取付座を、トリムボードの金型の離型方向に沿って離型可能に形成させることで、トリムボードの金型にスライドコア等を設ける必要がなくなるので、金型構造が簡易になり、大幅なコストダウンを図ることができる。
【０１１２】
請求項３に記載の発明ではトリムボードに対するクリップの脱着が可能となる。また、拡幅防止リブを環状とすることで、第１取付座の先端側の全周を覆うため、第１係合部が第１取付座からさらに抜け難くなり、第１取付座に対する第１係合部の抜け強度を高めることができる。
【０１１３】
このように、第１取付座に対する第１係合部の抜け強度を高めることで、第１取付座の肉厚を薄くすることが可能となるため、第１取付座の裏面側に生じるひけを小さくすることができる。また、第１取付座の肉厚を薄くすることで、第１取付座の先端側に設けられた球状凹部の深さを浅くすることができる。
【０１１４】
従って、アンダーカット部を小さくすることができるので、トリムボードが金型から離型し易くなり、トリムボードの表面に、金型に配設されたエジェクターピンによる白化が生じたり、また、トリムボードが変形したりする恐れはない。
【０１１５】
請求項４に記載の発明では、トリムボードに係合して固定させると共に、クリップが装着可能なリテーナ部材を用いることで、部品点数は増えてしまうが、複雑な形状でも金型構造を単純化させることができるため、金型加工費の削減を図ることができる。
【０１１６】
請求項５に記載の発明では、第２取付座を板部材とし、第２係合部に突起部を設けてこの突起部を板部材の表面に食付かせることで、トリムボードにクリップを取付けることが可能となり、トリムボードには無理抜き可能なアンダーカット部を設ける必要はなくなる。このため、トリムボードの金型の離型性が向上する。また、単純な構成であるため、金型製作期間を短縮させることができ、金型費用の削減を図ることができる。
【０１１７】
請求項６に記載の発明では、突起部が係合リブに食付くこととなり、板部材に対して食付き易くなる。また、突起部が係合リブに対して直交した状態で食付くことで、板部材に対する食付き性が良くなる。
【０１１８】
請求項７に記載の発明では、第２取付座を単に円筒状のボスとすることで、請求項６に記載の発明と比較してさらに、金型製作期間を短縮させることができ、金型費用の削減を図ることができる。また、ボスにネジ部材をねじ込み、ネジ部を形成しながら、ボスに第２係合部を係合させるため、リテーナ部材がトリムボードにしっかり固定される。

[Problems to be solved by the invention]
The present invention has been made in view of the above-described circumstances, and has as its object to provide a clip that is easy to work with and that does not easily come off the trim board, and a trim board mounting structure using the clip.
[0012]
[Means for Solving the Problems]
According to the first aspect of the present invention, it is possible to release the mold along the mold release direction of the mold for molding the trim board to be attached to the body panel, and to engage with the first mounting seat projecting from the trim board and capable of widening. A first engaging portion that can be inserted into the first mounting seat by widening the first mounting seat, and the clip is disposed at a predetermined distance from the first engaging portion; A widening prevention rib that is located outside the first mounting seat when the first engaging portion is inserted into the first mounting seat to prevent the first mounting seat from widening; and a side opposite to the first engaging portion. An umbrella portion that can be in contact with the body panel, an insertion portion that stands upright from the center of the umbrella portion and can be inserted into a hole formed in the body panel, and an insertion portion that is provided so as to be able to be sandwiched by the insertion portion. With the part inserted into the hole, the inner edge of the body panel is interposed between the umbrella and the umbrella. It is characterized with lifting capable claw portion, in that it is configured.
[0013]
According to the first aspect of the invention, the clip is provided with the first engagement portion, and the first engagement portion is widened by the first engagement portion, so that the first engagement portion is inserted into the first attachment seat. Workability is good because the clip is inserted and the clip is engaged with the trim board.
[0014]
Also, by providing a widening prevention rib on the clip, and in a state where the first engagement portion is inserted into the first mounting seat, the clip is positioned outside the first mounting seat to prevent the first mounting seat from widening. The first engagement portion can be prevented from coming off the first mounting seat.
[0015]
On the other hand, on the opposite side of the first engaging portion, an umbrella portion that can be in contact with the body panel is provided, and an insertion portion is erected from the center of the umbrella portion so that it can be inserted into a hole formed in the body panel. I have.
[0016]
The insertion portion is provided with a claw portion capable of being pinched, and the inner edge portion of the body panel is held between the claw portion and the umbrella portion in a state where the insertion portion is inserted into the hole portion. Thus, the trim board can be fixed to the body panel via the clip.
[0017]
Here, the clip can be slightly swung with respect to the first mounting seat by making the first mounting seat a substantially spherical concave portion and the first engaging portion a substantially spherical body. For this reason, it is possible to absorb a positional shift between the trim board and the body panel.
[0018]
According to a second aspect of the present invention, in a trim board mounting structure for mounting a trim board to a body panel via a clip, the trim board can be released along a releasing direction of a mold for molding the trim board and can be widened. A first mounting seat protrudes from the trim board, and the clip expands the first mounting seat and inserts the first mounting seat into the first mounting seat. A widening prevention rib which is arranged at a distance, is located outside the first mounting seat in a state where the first engagement portion is inserted into the first mounting seat, and prevents the first mounting seat from widening; An umbrella portion located on the opposite side of the first engagement portion and capable of face-to-face contact with the body panel; an insertion portion erected from the center of the umbrella portion and insertable into a hole formed in the body panel; Is provided so as to be able to be sandwiched, and in a state where the insertion portion is inserted through the hole portion, The have a sandwich capable claw portion inner edge of the body panel, in characterized in that it is constituted with the part.
[0019]
According to the invention described in claim 2, the trim board is attached to the body panel via the clip. Here, a first mounting seat is protruded from the trim board, and the first mounting seat can be released along a release direction of a mold for molding the trim board.
[0020]
For example, when an undercut portion that cannot be forcibly removed (the overcut of the undercut portion is large) is provided in a direction perpendicular to the mold release direction of the mold of the trim board, the undercut portion is formed. For this purpose, it is necessary to provide a slide core or an inclined pin in the mold structure in the undercut portion. For this reason, the mold structure becomes complicated, and the mold cost increases.
[0021]
However, by forming the first mounting seat protruding from the trim board in a mold releasing direction of the trim board mold (including an undercut portion that can be forcibly removed), the metal of the trim board is formed. Since there is no need to provide a slide core or the like on the mold, the mold structure is simplified, and a significant cost reduction can be achieved.
[0022]
According to the third aspect of the present invention, when the widening prevention rib is formed in an annular shape, the widening prevention rib and the first engaging portion are connected by a thin portion, and the first engaging portion is inserted into the first mounting seat. Then, the thin portion is cut to separate the widening prevention rib from the first engagement portion.
[0023]
For example, when the height of the first mounting seat is higher than the height of the widening preventing rib, the widening preventing rib separated from the first engaging portion in a state where the first engaging portion is inserted into the first mounting seat. Is moved toward the base of the first mounting seat, the distal end of the first mounting seat becomes free.
[0024]
Since the amount of widening of the first mounting seat is larger at the distal end than at the base of the first mounting seat, in this state, the first mounting seat can be widened, and the first engagement portion can be removed. Therefore, according to the third aspect of the present invention, the clip can be attached to and detached from the trim board.
[0025]
In addition, since the widening prevention rib is formed in an annular shape, it covers the entire circumference of the first mounting seat on the distal end side, so that the first engagement portion is more difficult to come off from the first mounting seat, and the first engagement with the first mounting seat. The joint strength can be increased.
[0026]
As described above, by increasing the pull-out strength of the first engagement portion with respect to the first mounting seat, the thickness of the first mounting seat can be reduced. For this reason, sink marks generated on the back surface side of the first mounting seat can be reduced.
[0027]
In addition, by reducing the thickness of the first mounting seat, the depth of the spherical concave portion provided on the distal end side of the first mounting seat can be reduced. Accordingly, since the undercut portion can be reduced, the trim board can be easily released from the mold, and the surface of the trim board may be whitened by the ejector pins disposed on the mold, or the trim board may be damaged. There is no risk of deformation.
[0028]
The invention according to claim 4, wherein a clip is engaged with a retainer member, the retainer member is fixed to a trim board, and the clip is mounted on a body panel, and the trim board is mounted on the body panel. In the mounting structure, a second mounting seat that is released along the release direction of a mold for molding the trim board projects from the trim board, and the clip is an umbrella portion that can face the body panel. An insertion portion that is erected from the center of the umbrella portion and that can be inserted into a hole formed in the body panel; and an inner edge portion of the body panel is sandwiched between the insertion portion and the umbrella portion so as to be able to be sandwiched.

And a mounting portion for engaging the clip by sandwiching a peripheral portion of the cutout portion.
[0029]
In the invention described in claim 4, the clip is engaged with the retainer member, the retainer member is fixed to the trim board, and the clip is attached to the body panel, and the trim board is attached to the body panel. Here, a second mounting seat protrudes from the trim board, and the second mounting seat can be released along the release direction of a mold for molding the trim board.
[0030]
On the other hand, the clip is provided with an umbrella portion that can be interviewed with the body panel, and an insertion portion is erected from the center of the umbrella portion so that the clip can be inserted into a hole formed in the body panel. The insertion portion is provided with a claw portion so as to be able to be pinched, and the inner edge portion of the body panel is pinched between the claw portion and the umbrella portion in a state where the insertion portion is inserted into the hole portion.
[0031]
Here, a first holding plate is provided so as to overlap the umbrella portion, and a shaft portion stands upright from the first holding plate. At the end of the shaft portion, a second holding plate is provided in parallel with the first holding plate. On the other hand, the retainer member is provided with a second engagement portion engageable with the second mounting seat, and the second engagement portion is engaged with the second mounting seat to fix the retainer member to the trim board.

The formed shaft portion forms a notch portion that can enter.
[0033]
With the shaft portion standing upright from the first holding plate entering the notch portion, the peripheral portion of the notch portion is held between the first holding plate and the second holding plate of the clip. Thereby, the clip is mounted on the mounting portion.
[0034]
As described above, the number of components is increased by using the retainer member to which the clip can be attached while being engaged with and fixed to the trim board, but the mold structure can be simplified even with a complicated shape. In addition, it is possible to reduce the mold processing cost.
[0035]
According to the fifth aspect of the invention, the second mounting seat is a pair of plate members, and the second engagement portion is a surrounding rib. On the surface of the surrounding rib, a projecting portion that can bite the plate member protrudes, and the surrounding rib presses the projecting portion against the plate member while surrounding the surface of the plate member.
[0036]
In this way, the clip can be attached to the trim board by providing the second mounting seat as a plate member, providing the protrusion on the second engagement portion and making this protrusion bite on the surface of the plate member, There is no need to provide an undercut portion that can be forcibly removed from the trim board. For this reason, the releasability of the mold of the trim board is improved. In addition, because of the simple configuration, the mold manufacturing period can be shortened, and the cost of the mold can be reduced.

BEST MODE FOR CARRYING OUT THE INVENTION
A clip according to a first embodiment of the present invention and a trim board mounting structure using the clip will be described.
[0042]
As shown in FIG. 3, a trim board 14 can be fixed to a body panel 10 of the vehicle via a clip 12. A substantially cylindrical mounting seat 16 (first mounting seat) is provided upright on the trim board 14, and a spherical concave portion 18 is formed on the inner surface on the distal end side of the mounting seat 16 along the circumferential direction of the mounting seat 16. Have been. In addition, a pair of inverted U-shaped notches 20 are formed from the tip of the mounting seat 16 along the axial direction of the mounting seat 16.
[0043]
By the way, the trim board 14 is formed by a mold (not shown), and the parting line of the mold is set to the front surface or the back surface of the trim board 14. Here, the mounting seat 16 is provided perpendicular to the back surface of the trim board 14 and is formed along the mold releasing direction.
[0044]
For this reason, the spherical concave portion 18 formed in the mounting seat 16 corresponds to a direction orthogonal to the mold releasing direction, that is, a so-called undercut portion. The depth and width are set to dimensions that allow forcible removal of the mold.
[0045]
On the other hand, the clip 12 is provided with a substantially annular pedestal 22, an annular rib 24 is erected from the inner edge of the pedestal 22, and a hollow ball 26 (first 1 engaging portion) are provided integrally.
[0046]
The outer diameter of the ball 26 is slightly larger than the inner diameter of the mounting seat 16 and is large enough to be in contact with the spherical recess 18 formed in the mounting seat 16. Outside the ball 26, a pair of arc-shaped widening prevention ribs 28 stand upright from the upper surface of the pedestal 22 on the concentric circle of the pedestal 22 with the ball 26 interposed therebetween.
[0047]
The distance between the widening prevention ribs 28 is slightly larger than the outer diameter of the mounting seat 16, and can be inserted into the mounting seat 16. The widening prevention rib 28 has a height such that about half of the ball 26 is exposed from the widening prevention rib 28 in a front view of the clip 12, and a chamfered portion 30 is formed on the inner surface of the distal end portion.
[0048]
On the other hand, from the lower surface side of the pedestal 22, an annular umbrella portion 32 projects obliquely downward. The umbrella portion 32 is large enough to be in contact with the peripheral edge of the circular hole portion 10A formed in the body panel 10.
[0049]
From the center of the umbrella portion 32, a substantially cylindrical insertion portion 34 having a tapered portion 34A formed at the tip thereof hangs down. A pair of cutouts 36 having a substantially U-shape with a downward opening are cut into the insertion portion 34, and a claw portion 38 having a substantially triangular cross section is provided inside the cutout 36. 34 from the outer peripheral surface.
[0050]
When the claw portion 38 is pressed, the claw portion 38 is bent inward, and can be sandwiched (the separation distance between the claw portions 38 is short). Here, the claw portion 38 is formed so as to be wider than the inner diameter of the circular hole portion 10 A of the body panel 10. It becomes possible to pass through the hole 10A.
[0051]
Next, a method of attaching the trim board will be described.
[0052]
As shown in FIG. 2A, the clip 12 is positioned so that the widening prevention rib 28 of the clip 12 is not disposed below the notch 20 of the mounting seat 16, and the ball of the clip 12 is inserted into the mounting seat 16. 26 is inserted.
[0053]
Since the outer diameter of the ball 26 is slightly larger than the inner diameter of the mounting seat 16, the movement of the ball 26 is restricted when the ball 26 comes into contact with the tip of the mounting seat 16.
[0054]
For this reason, the ball 26 is pressed into the mounting seat 16 as shown in FIG. Thereby, the front end side of the mounting seat 16 is expanded in diameter by the pair of notches 20 formed in the mounting seat 16, and the ball 26 can be inserted into the mounting seat 16.
[0055]
At this time, the distal end side of the widening prevention rib 28 abuts against the front end of the mounting seat 16, but with the insertion of the ball 26, the front end of the mounting seat 16 is reduced in diameter by the chamfered portion 30 formed on the widening prevention rib 28. Guided in the direction of
[0056]
Then, as shown in FIG. 2 (C), the mounting seat 16 is disposed between the ball 26 and the widening prevention rib 28 along the outer surface of the ball 26, and a spherical concave portion formed on the inner surface on the distal end side of the mounting seat 16. The clip 12 is engaged with the outer surface of the ball 26 in contact with the clip 18, and the clip 12 is fixed to the trim board 14 with the movement restricted.
[0057]
Next, as shown in FIG. 3, the insertion portion 34 formed on the clip 12 is inserted into the circular hole 10A formed on the body panel 10. Since the claw portion 38 provided in the insertion portion 34 is formed so as to be wider than the inner diameter of the circular hole portion 10A of the body panel 10, when the insertion portion 34 is inserted into the circular hole portion 10A, a circle is formed. The claw portion 38 contacts the inner edge of the hole 10A.
[0058]
When the clip 12 is pressed toward the body panel 10 in this state, the claw 38 is reduced in diameter and passes through the circular hole 10A with the movement of the insertion portion 34. Thus, when the claw portion 38 passes through the circular hole portion 10A, the claw portion 38 is restored, and the peripheral portion of the circular hole portion 10A is sandwiched between the umbrella portion 32 and the claw portion 38. Thus, the trim board 14 is attached to the body panel 10 via the clip 12.
[0059]
Here, the clip 12 is attached to the body panel 10 after the clip 12 is engaged with the trim board 14. However, after the clip 12 is attached to the body panel 10, the trim board 14 is engaged with the clip 12. You may let it.
[0060]
Next, the operation of the clip according to the first embodiment of the present invention and the trim board mounting structure using the clip will be described.
[0061]
Since the mounting seat 16 of the trim board 14 is provided perpendicular to the back surface of the trim board 14 and is formed along the mold releasing direction, there is no need to provide a slide core or the like in the mold of the trim board 14. In addition, the mold structure is simplified, and the cost can be significantly reduced.
[0062]
Here, the spherical concave portion 18 formed in the mounting seat 16 corresponds to a so-called undercut portion. However, depending on the material of the trim board 14, the depth and the width of the spherical concave portion 18 are set to dimensions that can be forcibly removed from the mold. The spherical concave portion 18 can be released from the mold regardless of the slide core or the inclined pin.
[0063]
Also, a ball 26 is provided on the clip 12, the mounting seat 16 is widened by the ball 26 and inserted into the mounting seat 16, and a widening prevention rib 28 is provided outside the ball 26. The clip 12 can be easily engaged with the mounting seat 16 by arranging the mounting seat 16 outside the mounting seat 16 in a state where the clip 12 is inserted into the mounting seat 16 so as not to widen. 16 can be prevented from falling out.
[0064]
Further, the clip 12 can be slightly swung with respect to the mounting seat 16 by providing a spherical recess 18 in the mounting seat 16 and engaging the ball 26 with the spherical recess 18. 10 can be absorbed.
[0065]
In addition, by making the ball 26 hollow, the surface of the ball 26 does not sink after the clip 12 is formed. As a result, variation in the dimensions of the ball 26 can be prevented.
[0066]
Here, the mounting seat 16 is widened using the ball 26, and the widening of the mounting seat 16 is prevented by the widening prevention rib 28. However, after the mounting seat is widened and the clip is engaged, the width of the mounting seat 16 is widened. However, the present invention is not limited to this as long as it can be prevented.
[0067]
Next, a clip according to a second embodiment of the present invention and a trim board mounting structure using the clip will be described. Note that description of contents substantially the same as those in the first embodiment is omitted.
[0068]
As shown in FIGS. 4 and 5 (A), the thin wall is provided at 90 ° intervals from the outer surface of the ball 26 provided on the clip 39 at a position parallel to the pedestal 22 and at a position where the ball 26 is bisected vertically. The piece 40 is overhanging. The thin piece 40 tapers toward the distal end, and a lower end of an annular rib 41 is connected to the distal end of the thin piece 40 and covers the upper half of the ball 26.
[0069]
When the annular rib 41 is moved vertically with respect to the ball 26, the thin piece 40 is broken, and the length of the annular rib 41 is larger than the length from the base of the mounting seat 16 to the spherical recess 18. Has also become shorter.
[0070]
Next, a method of attaching the trim board will be described.
[0071]
As shown in FIGS. 5A and 5B, the annular rib 41 is moved up and down with respect to the ball 26 to break the thin piece 40, and the annular rib 41 is separated from the ball 26. With the annular rib 41 disposed outside the ball 26, the ball 26 is pressed into the mounting seat 16 as shown in FIG.
[0072]
The notch 20 formed in the mounting seat 16 increases the diameter of the distal end of the mounting seat 16, and the ball 26 is inserted into the mounting seat 16. At this time, the distal end of the mounting seat 16 abuts on the chamfered portion 41A formed at the distal end of the annular rib 41, whereby the annular rib 41 is arranged concentrically with the ball 26 and the distal end of the mounting seat 16 is formed. Is guided in the direction of reducing the diameter.
[0073]
Then, as shown in FIG. 5 (D), the mounting seat 16 is disposed between the ball 26 and the annular rib 41 along the outer surface of the ball 26, and the spherical concave portion 18 formed on the inner surface on the distal end side of the mounting seat 16 is formed. The clip 39 is engaged with the outer surface of the ball 26 in contact with the clip 26, and the clip 39 is fixed to the trim board 14 in a state where movement is restricted.
[0074]
Next, the operation of the clip according to the second embodiment of the present invention and the trim board mounting structure using the clip will be described.
[0075]
Here, the thin piece 40 for connecting the ball 26 and the annular rib 41 is broken and separated from the ball 26, and the length of the annular rib 41 is shorter than the length from the base of the mounting seat 16 to the spherical concave portion 18. are doing.
[0076]
Thereby, as shown in FIGS. 6A and 6B, after the clip 12 is fixed to the mounting seat 16, the annular rib 41 is moved above the mounting seat 16, so that the distal end side of the mounting seat 16. Can be free. Therefore, as shown in FIG. 6C, the clip 12 can be removed from the mounting seat 16, and the clip 12 can be attached to and detached from the mounting seat 16.
[0077]
On the other hand, in a state where the clip 12 is fixed to the mounting seat 16, the entire periphery of the distal end side of the mounting seat 16 is covered by the annular rib 41, so that the clip 39 is more difficult to come off from the mounting seat 16, and Can be increased.
[0078]
As described above, the thickness of the mounting seat 16 can be reduced by increasing the detachment strength of the clip 39 with respect to the mounting seat 16. Therefore, sink marks generated on the rear surface side of the mounting seat 16 can be reduced.
[0079]
Further, by reducing the thickness of the mounting seat 16, the depth of the spherical concave portion 18 provided on the distal end side of the mounting seat 16 can be reduced. Therefore, since the undercut portion can be reduced, the trim board 14 is easily released from the mold, and the surface of the trim board 14 is whitened by the ejector pins disposed on the mold, The possibility that the trim board 14 is deformed is small.
[0080]
Next, a clip according to a third embodiment of the present invention and a trim board mounting structure using the clip will be described. Note that description of contents substantially the same as those in the first embodiment is omitted.
[0081]
As shown in FIG. 7, here, a retainer member 44 that can be fixed to the trim board 42 is used, and a clip 46 is engaged with the retainer member 44.
[0082]
A pair of plate members 48 are provided upright on the trim board 42, and a narrow width portion 48 A whose width is gradually narrowed is formed at the tip. A plurality of engaging ribs 50 are protruded in parallel from the front and back surfaces of the plate member 48 along the direction in which the plate member 48 stands up, except for the sandwiched portion 48A.
[0083]
On the other hand, the retainer member 44 includes a mounting part 52 and an engaging part 54. The mounting portion 52 has a substantially rectangular parallelepiped shape, and an engaging portion 54 is continuously provided on the upper surface of the mounting portion 52.
[0084]
Here, an upright wall 56 which is formed in a substantially S-shape in plan view and which can surround the plate member 48 is provided upright at the engagement portion 54, and the interval between the facing wall surfaces 56 A is It is slightly separated from the wall thickness.
[0085]
Further, a projecting portion 58 protrudes from the facing wall surface 56A along a direction orthogonal to the direction of engagement of the retainer member 44 with the trim board 42 (the direction of the arrow). At least the projections 58 are formed of a material having higher rigidity than the plate member 48, and the distance between the front ends of the projections 58 facing each other is determined by the engagement rib 50 formed on one plate member 48. It is shorter than the separation distance between the tips. For this reason, in a state where the engagement portion 54 is engaged with the plate member 48, the projection 58 bites into the engagement rib 50.
[0086]
On the other hand, the mounting portion 52 is hollow, and the lower surface of the mounting portion 52 is cut across the center of the lower surface along a direction orthogonal to the direction in which the retainer member 44 is engaged with the trim board 42. The notch 60 is notched. The notch 60 has an engagement hole 60A (described later) at the center of the lower surface, the width on the opening 60B side is wide, and the entrance 60C to the engagement hole 60A has a narrow width.
[0087]
Here, the clip 46 mounted on the mounting portion 52 will be described. The description of the contents substantially the same as the clip 12 is omitted.
[0088]
As shown in FIGS. 7 and 8A, a holding plate 64 is provided above the umbrella portion 62 provided on the clip 46 so as to overlap the umbrella portion 62. A shaft portion 66 stands upright from the holding plate 64, and a holding plate 68 is provided at an end of the shaft portion 66 at a predetermined distance in parallel with the holding plate 64. The outer diameter of the holding plates 64, 68 is larger than the inner diameter of the engagement hole 60A of the notch 60 of the mounting portion 52.
[0089]
By the way, the shaft portion 66 of the clip 46 can enter the notch portion 60 of the mounting portion 52 along the notch direction of the notch portion 60, and the inner diameter of the engagement hole 60A of the notch portion 60 is formed. The size is slightly larger than the outer diameter of the shaft portion 66.
[0090]
The width of the inlet 60C of the notch 60 is slightly smaller than the outer diameter of the shaft 66, and after passing through the opening 60B of the notch 60, the shaft 66 becomes the inlet 60C. The shaft 66 can be made to enter the engagement hole 60A by press fitting.
[0091]
On the other hand, the separation distance between the holding plate 64 and the holding plate 68 is substantially the same as the thickness of the lower surface of the mounting portion 52, and the lower surface of the mounting portion 52 can be held between the holding plate 64 and the holding plate 68. Has become.
[0092]
Next, a method of attaching the trim board will be described.
[0093]
First, the shaft 66 of the clip 46 is inserted into a cutout 60 formed in the mounting portion 52 of the retainer member 44. At this time, the lower surface of the mounting portion 52 is in a state of being sandwiched between the sandwiching plate 64 and the sandwiching plate 68, and in this state, the shaft portion 66 is moved toward the engagement hole 60 A of the notch portion 60. .
[0094]
When the shaft portion 66 comes into contact with the inlet portion 60C of the notch portion 60 and is restricted from moving, the shaft portion 66 is press-fitted and made to enter the engaging hole 60A, and the peripheral edge portion of the engaging hole 60A is And the holding plate 68.
[0095]
Here, since the inner diameter of the engagement hole 60A is larger than the outer diameter of the shaft portion 66, the retainer member 44 and the clip 46 are connected to each other while the shaft portion 66 is inserted into the engagement hole 60A. Some play is provided between them.
[0096]
Next, as shown in FIGS. 8A and 8B, the retainer member 44 is engaged with the plate member 48 of the trim board 42. After the retainer member 44 is positioned so that the sandwiched portion 48A of the plate member 48 is disposed between the wall surfaces 56A of the upright wall 56 of the engagement portion 54, the retainer member 44 is pressed into the plate member 48. As a result, the protrusion 58 moves to the back of the plate member 48 while biting the engagement rib 50, and the retainer member 44 is fixed to the plate member 48.
[0097]
Then, the insertion portion 34 formed in the clip 46 is inserted into the circular hole portion 10A formed in the body panel 10, and the peripheral portion of the circular hole portion 10A is pinched between the umbrella portion 62 and the claw portion 38. Let it. Thus, the trim board 42 is attached to the body panel 10 via the clip 46.
[0098]
Next, the operation of the clip according to the third embodiment of the present invention and the trim board mounting structure using the clip will be described.
[0099]
As shown in FIG. 7, the use of the retainer member 44 including the engaging portion 54 to be engaged with the trim board 42 and the mounting portion 52 to which the clip 46 can be mounted increases the number of components, but is complicated. Since the mold structure can be simplified even in the shape, the mold processing cost can be reduced.
[0100]
Further, a plate member 48 is formed on the trim board 42, a projection 58 is formed on the engaging portion 54 of the retainer member 44, and the projection 58 is bitten by the plate member 48, and the clip 46 is attached to the trim board 42. By fixing, there is no need to provide the trim board 42 with an undercut portion that can be forcibly removed.
[0101]
Therefore, the mold releasability of the trim board 42 is improved. Further, since it is not necessary to form an undercut portion such as the spherical concave portion 18 shown in FIG. 1, the mold manufacturing period can be shortened, and the mold cost can be reduced.
[0102]
Further, as shown in FIG. 7, an engagement rib 50 is formed along the engagement direction (arrow direction) of the engagement portion 54 to the plate member 48, and a direction orthogonal to the engagement rib 50 is formed. By providing the projections 58 along the projections, the projections 58 can easily bite against the plate member 48. In addition, since the protrusions 58 bite in a state perpendicular to the engagement ribs 50, biting properties with respect to the plate member 48 are improved.
[0103]
Also, by making the inner diameter of the engagement hole 60A larger than the outer diameter of the shaft portion 66 and providing a slight play between the retainer member 44 and the clip 46, the trim board 42 and the body panel 10 In the case where a slight positional deviation occurs between the positions, the dimensional absorption for the positional deviation can be achieved.
[0104]
Further, by forming the engaging portion 54 of the retainer member 44 as a substantially S-shaped upright wall 56 surrounding the plate member 48, it is possible to prevent the plate members 48 from being widened, and the protrusions are formed. It is possible to maintain the state in which the engagement ribs 58 bite into the engagement ribs 50.
[0105]
The engaging portion of the retainer member is not limited to this as long as it can be engaged with and fixed to a mounting seat formed along the mold releasing direction of the trim board mold.
[0106]
For example, as shown in FIGS. 9 and 10A, a cylindrical boss 72 (second mounting seat) is erected on the trim board 70 as an engaging portion. On the other hand, a tapping screw 74 may be erected from the upper surface of the mounting portion 52, and the retainer member 76 may be engaged with the trim board 70 by screwing the tapping screw 74 into the boss 72 as shown in FIG. .
[0107]
Accordingly, the shape of the second mounting seat can be simplified, so that the mold manufacturing period can be further shortened, and the cost of the mold can be reduced. Further, since the tapping screw 74 is screwed into the boss 72 and the retainer member 76 is engaged with the boss 72 while forming the female screw portion 72A, the retainer member 76 is firmly fixed to the trim board 70.
[0108]
Further, here, the tapping screw 74 is erected from the upper surface of the mounting portion 52, but the tapping screw 74 is not limited to this as long as the retainer member 76 can be engaged with the boss 72 of the trim board 70.
[0109]
For example, as shown in FIG. 11A, an engaging boss 82 having a female screw portion 82A may be provided upright on the upper surface of the mounting portion 80 of the retainer member 78. In this case, as shown in FIG. 11B, the retainer member 78 is engaged with the boss 86 while forming the male screw 86A on the outer peripheral surface of the boss 86 of the trim board 84.
[0110]
【The invention's effect】
Since the present invention is configured as described above, according to the first aspect of the present invention, the first mounting portion is located outside the first mounting seat in a state where the first engaging portion is inserted into the first mounting seat. The first engagement portion can be prevented from falling out of the first mounting seat by preventing the widening of the first engagement portion. Further, by forming the first mounting seat as a substantially spherical concave portion and the first engaging portion as a substantially spherical body, it is possible to absorb a positional shift between the trim board and the body panel.
[0111]
According to the second aspect of the present invention, the first mounting seat protruding from the trim board is formed so as to be releasable along the mold releasing direction of the trim board mold, so that the slide core is formed on the trim board mold. Since there is no need to provide such components, the mold structure can be simplified, and the cost can be significantly reduced.
[0112]
According to the third aspect of the present invention, the clip can be attached to and detached from the trim board. In addition, since the widening prevention rib is formed in an annular shape, it covers the entire circumference of the first mounting seat on the distal end side, so that the first engagement portion is more difficult to come off from the first mounting seat, and the first engagement with the first mounting seat. The joint strength can be increased.
[0113]
As described above, by increasing the detachment strength of the first engagement portion with respect to the first mounting seat, it is possible to reduce the thickness of the first mounting seat. Can be smaller. In addition, by reducing the thickness of the first mounting seat, the depth of the spherical concave portion provided on the distal end side of the first mounting seat can be reduced.
[0114]
Accordingly, since the undercut portion can be reduced, the trim board can be easily released from the mold, and the surface of the trim board may be whitened by the ejector pins disposed on the mold, or the trim board may be damaged. There is no risk of deformation.
[0115]
According to the fourth aspect of the present invention, the number of components is increased by using a retainer member to which the clip can be attached while being engaged with and fixed to the trim board, but the mold structure is simplified even in a complicated shape. Therefore, the mold processing cost can be reduced.
[0116]
According to the fifth aspect of the present invention, the clip is attached to the trim board by providing the second mounting seat as a plate member, providing the second engagement portion with a projection, and making the projection bite on the surface of the plate member. Therefore, it is not necessary to provide the trim board with an undercut portion which can be forcibly removed. For this reason, the releasability of the mold of the trim board is improved. In addition, because of the simple configuration, the mold manufacturing period can be shortened, and the cost of the mold can be reduced.
[0117]
According to the sixth aspect of the invention, the projections bite into the engagement ribs, so that the projections easily bite into the plate member. In addition, since the protrusions bite in a state of being orthogonal to the engagement ribs, biting properties with respect to the plate member are improved.
[0118]
According to the invention described in claim 7, by simply using the second mounting seat as a cylindrical boss, the mold manufacturing period can be further shortened as compared with the invention described in claim 6, and Costs can be reduced. Further, the screw member is screwed into the boss, and the second engagement portion is engaged with the boss while forming the screw portion, so that the retainer member is firmly fixed to the trim board.
