Description

【０００１】
【発明の属する技術分野】
本発明は、車両のドア等に形成されたウインドウフレームに取着されるガラスランの取付構造に関するものである。
【０００２】
【従来の技術】
車両のフロントドアはドア本体の上部にウインドウフレームを設け、該ウインドウフレームの内周縁に形成された溝部にチャンネル状をなすガラスランを嵌入係止し、該ガラスランの車内外のガラスシール部によりウインドウガラスの昇降を案内するとともに、車室内外をシールするようになっている。
【０００３】
上記ガラスランは本体部として底壁部と、その車外側に位置する外側壁部と車内側に位置する内側壁部を備えて構成されている。前記内外両側壁部の高さは、ほぼ同じか内側壁部が外側壁部よりも若干高く形成されている。
【０００４】
【発明が解決しようとする課題】
最近、ドアの見映えを向上するため前記内側壁部の高さを外側壁部の高さの２〜４倍に設定したガラスランが用いられるようになっている。このガラスランのウインドウフレームへの取付構造を、図１４に基づいて説明する。
【０００５】
図１４はウインドウフレーム１３の横枠部の垂直断面を示す。ウインドウフレーム１３に設けた溝部２５にはガラスラン１５のチャンネル状をなす本体部１５ａが嵌入係止されている。前記本体部１５ａは底壁部１５ｂ、外側壁部１５ｃ及び内側壁部１５ｄにより構成され、外側壁部１５ｃ及び内側壁部１５ｄにはガラスシール部１５ｈ、１５ｉが形成され、ウインドウガラス１６を摺動案内する。前記外側壁部１５ｃには溝部２５の車外側の内壁面に設けた折り返し部２６の外端縁２６ａに係止される係止部１５ｊと前記折り返し部２６の内端縁２６ｂに係止される離脱阻止突部１５ｋが形成されている。
【０００６】
前記内側壁部１５ｄには延長内側壁部１５ｇが一体に形成され、その周縁に形成された被係止突部１５ｐがウインドウフレーム１３の係止突部３１を乗り越えるようにして係止されている。又、押上保持リップ１５ｏがウインドウフレーム１３の位置規制面３０に押圧され、遮蔽リップ１５ｑが係止突部３１に接触されている。前記延長内側壁部１５ｇの底壁部１５ｂからの高さＨ２は、前記外側壁部１５ｃの高さＨ１の約３倍となっている。
【０００７】
図１４の二点鎖線で示すように、ガラスラン１５に延長内側壁部１５ｇが無い場合には、内側壁部１５ｄの端縁に設けた押上保持リップ１５ｏと遮蔽リップ１５ｑを、ウインドウフレーム１３の位置規制面３０に係止する構成で位置決め保持される。このため、前記ウインドウフレーム１３の溝部２５に対しガラスラン１５の本体部１５ａを下方から上方へ直線移動して嵌入係止した後、位置規制面３０に押上保持リップ１５ｏを係止する取付方法が採られている。しかし、この直線移動して嵌入する方式は、外側壁部１５ｃ及び内側壁部１５ｄがガラスシール部１５ｈ、１５ｉ側へ向かって互いに接近する方向に押圧されるので、嵌入作業が円滑に行われないという問題がある。
【０００８】
一方、内側壁部１５ｄに延長内側壁部１５ｇがある場合には、押上保持リップ１５ｏと遮蔽リップ１５ｑの間に被係止突部１５ｐを設け、この被係止突部１５ｐが係止突部３１を乗り越えるようにして係止保持される構造をとる必要がある。このため、遮蔽リップ１５ｑの車外側の表面から押上保持リップ１５ｏまでの距離Ｌが長くなる。従って、ガラスラン１５を直線移動して溝部２５に嵌入する方法をとった場合、内側壁部１５ｄ及び延長内側壁部１５ｇを車外側へ大きく傾斜し、反対に外側壁部１５ｃは車内側に傾斜する必要があり、この結果、ガラスシール部１５ｈ、１５ｉが互いに干渉し合って嵌入操作が非常に煩わしいという問題が生じる。
【０００９】
本発明の目的は、上記の技術に存する問題点を解消して、ウインドウフレームに対するガラスランの取付作業を容易に行うことができるとともに、取付状態を安定して保持することができるガラスランの取付構造を提供することにある。

【００１８】
【発明の実施の形態】
以下、本発明を具体化した一実施形態を図１〜図１０に従って説明する。
図６は自動車の左側のフロントドア１１を車外側からみた正面図を示す。このフロントドア１１を構成するドア本体１２の上部には、ウインドウフレーム１３が装着されている。このウインドウフレーム１３とドア本体１２の上端縁とによりウインドウ開口１４が形成されている。前記ウインドウ開口１４の内周縁及びドア本体１２の内部にはガラスラン１５が装着され、ウインドウガラス１６の昇降動作を案内するようになっている。
【００１９】
図７はガラスラン１５のみを簡略化して車外側からみた正面図である。このガラスラン１５はウインドウフレーム１３の横枠部に対応する第１の押出成形部１７ａと、フロントドア１１の前側の縦枠部に対応する第２の押出成形部１７ｂと、後側の縦枠部と対応する第３の押出成形部１７ｃとにより構成されている。前記第１の押出成形部１７ａの前端部は第２の押出成形部１７ｂの上端部に対し第１の型成形部１８ａにより接続されている。第１の押出成形部１７ａの後端部は第３の押出成形部１７ｃの上端部に対し第２の型成形部１８ｂにより接続されている。なお、第２の押出成形部１７ｂと第３の押出成形部１７ｃのドア本体１２内に配設される部分は、それぞれ型成形部１８ｃ、１８ｄを介して小さな断面の押出成形部が接続されている。
【００２０】
前記ガラスラン１５の材質としては、例えばエチレン‐プロピレン‐ジエン三元共重合体（ＥＰＤＭ）等のゴム、オレフィン系熱可塑性エラストマー、軟質ポリ塩化ビニル等の軟質合成樹脂、あるいは、これらのポリマーブレンド材料を用いることができる。
【００２１】
ここで、図１、図７〜図１０の相互関係について説明すると、図１は図７の１‐１線と対応する第１の押出成形部１７ａの取付状態の断面、図８は図７の２‐２線と対応する第２の押出成形部１７ｂの取付状態の断面、図９は図７の３‐３線と対応する第３の押出成形部１７ｃの取付状態の断面、図１０は図７の４‐４線と対応する第３の押出成形部１７ｃの取付状態の断面をそれぞれ示す。
【００２２】
次に、図１及び図２に基づいて本発明の要部であるウインドウフレーム１３に対する第１の押出成形部１７ａの取付構造について説明する。
図１に示すように、ウインドウフレーム１３を構成する金属材料よりなるインナーパネル２１の内周側には、同じく金属製のインナーリーンホース２２が図示しない連結手段を介して固定されている。前記インナーパネル２１の外側面には金属製のモール２３が溶接等により固定され、インナーパネル２１の内側面には合成樹脂製のフレームガーニッシュ２４が図示しない連結手段により固定される。
【００２３】
この実施形態では、前記インナーリーンホース２２の本体と、その外周側の屈曲部２２ａと、前記モール２３の外側壁部２３ａとによりガラスラン１５の本体部１５ａを嵌入保持する溝部２５が形成されている。前記モール２３の内周縁部は車内側に位置するように折り返し部２６が一体に形成されている。前記溝部２５の底壁面２７は前記屈曲部２２ａにより、車外側の内壁面２８は、モール２３の外側壁部２３ａにより、車内側の内壁面２９はインナーリーンホース２２本体の側壁部によりそれぞれ構成されている。
【００２４】
前記ガラスラン１５の本体部１５ａは、底壁部１５ｂ、外側壁部１５ｃ及び内側壁部１５ｄによりチャンネル状に形成されている。前記底壁部１５ｂと外内側壁部１５ｃ、１５ｄは車外側及び車内側の円弧状をなす屈曲部１５ｅ、１５ｆにより自由状態で図３に示すように展開可能に連結されている。前記内側壁部１５ｄの内周縁には延長内側壁部１５ｇが一体に形成され、外側壁部１５ｃの内周縁にはウインドウガラス１６の表面１６ａに接触されるガラスシール部１５ｈが形成され、内側壁部１５ｄの外表面にはウインドウガラス１６の裏面１６ｂに接触されるガラスシール部１５ｉが一体に形成されている。
【００２５】
図１に示すように、前記内側壁部１５ｄ及び延長内側壁部１５ｇの底壁部１５ｂからの高さＨ２は、前記外側壁部１５ｃの高さＨ１の約３倍となっている。
前記ガラスラン１５の外側壁部１５ｃの内周縁には車外側に指向するように係止部１５ｊが一体に形成され、この係止部１５ｊは折り返し部２６の外端縁２６ａに押圧接触されてモール２３との間のシールを行う。この外端縁２６ａがウインドウフレーム１３の車外側壁端縁となる。前記外側壁部１５ｃの外側面には図２に示すように折り返し部２６の内端縁２６ｂとの間に第１の隙間Ｇ１をもって対向する離脱阻止突部１５ｋが一体に形成されている。この第１の隙間Ｇ１は、図２に示すように係止部１５ｊと離脱阻止突部１５ｋの上下方向の間隔Ｗを、折り返し部２６の形成幅Ｄよりも大きく設定することにより形成される。
【００２６】
前記外側壁部１５ｃの外側面には前記底壁部１５ｂと対応するように外側保持リップ１５ｌが一体に形成され、この外側保持リップ１５ｌの先端部は前記溝部２５の内壁面２８に押圧接触されている。前記内側壁部１５ｄの車内側の外側面には前記底壁部１５ｂと対応するように内側保持リップ１５ｍが一体に形成され、この内側保持リップ１５ｍの先端部は前記溝部２５の内壁面２９に押圧接触されている。
【００２７】
図２において、前記溝部２５の内壁面２８、２９の間隔、つまり幅寸法は、非嵌入状態のガラスラン１５の前記外側保持リップ１５ｌ及び内側保持リップ１５ｍの先端部同士を結んだ幅寸法より小さく形成されている。そして、ガラスラン１５の嵌入状態において両保持リップ１５ｌ、１５ｍが圧縮されて内壁面２８、２９に押圧されるようにしている。
【００２８】
前記車外側の屈曲部１５ｅと底壁面２７との間には第２の隙間Ｇ２が設けられ、車外側の屈曲部１５ｅに一体形成した遮蔽リップ１５ｎは底壁面２７に軽く押圧接触され、第２の隙間Ｇ２を遮蔽するようにしている。前記車内側の屈曲部１５ｆは底壁面２７に押圧接触されている。
【００２９】
前記ガラスラン１５の延長内側壁部１５ｇの内周縁には、押上保持リップ１５ｏが一体に形成され、インナーリーンホース２２の内周縁に車外側へ湾曲した湾曲部２２ｂにより形成される係止部としての位置規制面３０に押上保持リップ１５ｏが押圧接触されている。又、延長内側壁部１５ｇの内周縁には、フレームガーニッシュ２４に一体形成された係止部としての係止突部３１を車外側から車内側へ乗り越えて係止される被係止部としての被係止突部１５ｐが一体に形成されている。さらに、延長内側壁部１５ｇの内周縁には係止突部３１の外側面に押圧接触される遮蔽リップ１５ｑが一体に形成されている。
【００３０】
次に、図８に基づいてウインドウフレーム１３の前側の縦枠部に対するガラスラン１５の第２の押出成形部１７ｂの取付構造について説明する。
図８に示すように、第２の押出成形部１７ｂにおいては、前記延長内側壁部１５ｇが省略され、内側壁部１５ｄに押上保持リップ１５ｏ、被係止突部１５ｐ及び遮蔽リップ１５ｑが形成されている。又、前記インナーリーンホース２２に形成したフランジ部２２ｃにモール２３が接合され、この接合部に前記係止部１５ｊが係止されている。この係止部１５ｊには前記モール２３を遮蔽する遮蔽リップ１５ｒが形成されている。前記係止部１５ｊ及び遮蔽リップ１５ｒはフレームガーニッシュ２４Ａにより遮蔽されている。
【００３１】
第２の押出成形部１７ｂは本体部１５ａに対しウインドウガラス１６が出入りすることはなく昇降されるのみのため、ガラスシール部１５ｈはガラスシール部１５ｉの指向方向と反対方向、つまり外側方に指向されている。
【００３２】
図９は、ウインドウフレーム１３の後側の縦枠部に対するガラスラン１５の第３の押出成形部１７ｃの取付構造を示す。
第３の押出成形部１７ｃの取付構造は、図８に示す第２の押出成形部１７ｂの取付構造と基本的に同様である。但し、モール２３に対し係止部１５ｊが係止され、外側保持リップ１５ｌに離脱阻止突部１５ｋの機能を兼用させている構成が異なる。
【００３３】
図１０は、ベルトラインより下方の第３の押出成形部１７ｃの取付構造を示す。この部位のガラスラン１５においては、ドア本体１２の内部に収容される関係でガラスシール部１５ｈ、遮蔽リップ１５ｑ、被係止突部１５ｐ、押上保持リップ１５ｏ等が省略されている。
【００３４】
次に、ドア本体１２及びウインドウフレーム１３に対するガラスラン１５の取付方法を説明する。
図７に示すガラスラン１５を構成する第１〜第３の押出成形部１７ａ〜１７ｃの取り付け作業の概要を説明すると、第２の型成形部１８ｂを図６のウインドウ開口１４の上部後端部に取り付けることから開始される。次に、第１の押出成形部１７ａをその後端部から前端部へ連続的にウインドウフレーム１３の溝部２５に嵌入する。さらに、第１の型成形部１８ａを溝部２５に嵌入し、第２の押出成形部１７ｂの取付作業を上端部から下端部へ向かって行う。その後、第３の押出成形部１７ｃの取付作業を上端部から下端部へ向かって行う。
【００３５】
そこで、第１の押出成形部１７ａの取付作業について説明すると、本体部１５ａを図３に示す展開状態から同図の鎖線で示すように使用状態に変形させる。この状態で図４に示すようにウインドウフレーム１３の溝部２５に第１の押出成形部１７ａの本体部１５ａを傾斜状態で進入させ、折り返し部２６の外端縁２６ａに係止部１５ｊを係止する。
【００３６】
そして、延長内側壁部１５ｇを上方に押し上げると、本体部１５ａが係止部１５ｊ（外端縁２６ａ）を中心に図４の時計回り方向に回動される。この回動動作により内側保持リップ１５ｍが溝部２５の内壁面２９に押圧されるとともに、外側保持リップ１５ｌが内壁面２８に接近される。
【００３７】
図５に示すように、溝部２５の底壁面２７に車内側の屈曲部１５ｆが押圧されるまで本体部１５ａを回動させると、外側保持リップ１５ｌ及び内側保持リップ１５ｍが圧縮されて円弧状に湾曲されるとともに、遮蔽リップ１５ｎが底壁面２７に接触される。
【００３８】
次に、図５において延長内側壁部１５ｇを矢印で示すように車内側へ押圧すると、押上保持リップ１５ｏ及び被係止突部１５ｐが弾性変形しつつ係止突部３１を車内側に乗り越えて移動され、図１に示すように押上保持リップ１５ｏが位置規制面３０に押圧接触されるとともに、被係止突部１５ｐが係止突部３１に係止される。又、遮蔽リップ１５ｑは係止突部３１の外側面に押圧接触される。この状態では押上保持リップ１５ｏの圧縮反力により延長内側壁部１５ｇ及び内側壁部１５ｄが上方に付勢されるので、本体部１５ａは溝部２５内の所定位置に保持される。
【００３９】
図８、図９に示す前記ガラスラン１５の第２の押出成形部１７ｂ及び第３の押出成形部１７ｃの取付作業は、延長内側壁部１５ｇが無いので、本体部１５ａを溝部２５に直線移動して嵌入し、その後に押上保持リップ１５ｏ及び被係止突部１５ｐを係止突部３１の車内側に移動することにより行われる。この嵌入動作に代えて、前述した回動方式の嵌入動作と同様の嵌入動作を行うようにしてもよい。
【００４０】
上記実施形態のガラスラン１５の取付構造によれば、以下のような特徴を得ることができる。
（１）前記実施形態では、ウインドウフレーム１３の折り返し部２６の外端縁２６ａにガラスラン１５の外側壁部１５ｃに設けた係止部１５ｊを係止して、該係止部１５ｊを中心にガラスラン１５を回動して溝部２５に取り付けるようにした。このため、ガラスラン１５の内側壁部１５ｄに延長内側壁部１５ｇがあっても取付作業を円滑に行うことができる。
【００４１】
なお、遮蔽リップ１５ｑの車外側の表面から押上保持リップ１５ｏまでの水平方向の距離Ｌは大きいが、図４、図５における本体部１５ａの前述した回動動作に支障はない。
【００４２】
（２）前記実施形態では、外側壁部１５ｃ及び内側壁部１５ｄの基端部に外側保持リップ１５ｌ及び内側保持リップ１５ｍを形成し、両リップ１５ｌ、１５ｍを弾性変形させて溝部２５の内外両壁面２８、２９に押圧接触するようにした。このため、本体部１５ａの底壁部１５ｂを両リップ１５ｌ、１５ｍの弾発力により所定位置に保持でき、外端縁２６ａに対する係止部１５ｊの押圧接触を安定して保持でき、外端縁２６ａと係止部１５ｊとの間に有害な隙間が発生するのを防止することができる。
【００４３】
（３）前記実施形態では、本体部１５ａを回動して溝部２５に嵌入する行程において、外側保持リップ１５ｌを断面が扁平状から先端ほど下方に変位する円弧状に圧縮変形して内壁面２８に押圧接触するように構成した。このため、図２に示すように、外側保持リップ１５ｌが外側壁部１５ｃを持ち上げる機能を発揮し、取付完了後における前記有害な隙間の発生を防止することができる。この理由を以下に説明する。
【００４４】
前記ゴム製の外側保持リップ１５ｌの先端部は、モール２３の面粗度の高い裏面である内壁面２８に最初に接触した点Ｐ１から摩擦抵抗に抗してその接触点を下方に移動する、そして、最終接触点Ｐ２において、外側保持リップ１５ｌは円弧状に湾曲される。この外側保持リップ１５ｌの弾性変形量に応じて、溝部２５の内壁面２８には図２に示すように斜め下方に押圧力Ｆ１が作用する。この押圧力Ｆ１とモール２３及び外側保持リップ１５ｌの摩擦係数とにより外側保持リップ１５ｌの先端部は最終接触点Ｐ２において大きな摩擦抵抗力を受けるので、下方への滑動が阻止される。
【００４５】
一方、外側保持リップ１５ｌは接触点Ｐ１から最終接触点Ｐ２に移動されるまでの間に摩擦抵抗を受けるので、それにより外側保持リップ１５ｌ自体が円弧状に圧縮される。この圧縮量に応じて外側保持リップ１５ｌは図２に示すように最終接触点Ｐ２を介して斜め下方への押圧力Ｆ１をさらに大きくする。従って、この押圧力Ｆ１の反力Ｆ２の垂直成分Ｆ２ａによって外側壁部１５ｃが上方に持ち上げられ、外端縁２６ａに係止部１５ｊを押圧接触することができ、前記有害な隙間の発生を防止することができる。
【００４６】
（４）前記実施形態では、内側壁部１５ｄの基端外側面に底壁部１５ｂと対応して内側保持リップ１５ｍを設け、この内側保持リップ１５ｍを溝部２５の内壁面２９に押圧するようにした。又、前記内側保持リップ１５ｍは外側保持リップ１５ｌと同様に下向き円弧状に湾曲されて溝部２５の内壁面２９に押圧力Ｆ３で押圧されている。このため、その接触点Ｐ３においても、斜め上向きの反力Ｆ４が作用し、この反力Ｆ４の垂直成分Ｆ４ａによって内側壁部１５ｄが上方に持ち上げられ、内側保持リップ１５ｍが所定位置に安定して保持される。
【００４７】
前記内側保持リップ１５ｍの接触点Ｐ３は、押上保持リップ１５ｏ及び被係止突部１５ｐが係止突部３１を乗り越える際に、内側壁部１５ｄ及び延長内側壁部１５ｇが上方に持ち上げられるので、屈曲部１５ｆが一時的に圧縮されて最大高さまで引き上げられる。その後、屈曲部１５ｆの圧縮が解かれても接触点Ｐ３は摩擦抵抗力により下方に移動されずに所定位置に保持される。従って、内側保持リップ１５ｍが接触点Ｐ３に向かって圧縮され、外側保持リップ１５ｌと同様の機能を発揮することとなる。
【００４８】
前述した反力Ｆ４の水平成分Ｆ４ｂは前記反力Ｆ２の水平成分Ｆ２ｂと対抗して均衡し、底壁部１５ｂは車内外方から挟着されることになり、底壁部１５ｂは所定の取付位置に安定して保持される。
【００４９】
（５）前記実施形態では、ガラスラン１５の本体部１５ａの外側壁部１５ｃに対し離脱阻止突部１５ｋを形成し、この離脱阻止突部１５ｋと折り返し部２６の内端縁２６ｂとの間に第１の隙間Ｇ１が形成されるようにした。このため、前記係止部１５ｊと離脱阻止突部１５ｋの間隔Ｗと、折り返し部２６の形成幅Ｄに製造上の寸法誤差があっても、本体部１５ａを回動して溝部２５に嵌入する際、折り返し部２６に離脱阻止突部１５ｋが干渉しないので、嵌入動作を円滑に行うことができる。
【００５０】
（６）前記実施形態では、車外側の屈曲部１５ｅと底壁面２７との間に第２の隙間Ｇ２を設け、車外側の屈曲部１５ｅに遮蔽リップ１５ｎを形成したので、車外側の屈曲部１５ｅが底壁面２７に接触して外端縁２６ａから係止部１５ｊが浮き上がるのを防止することができる。又、遮音性能が向上し底壁部１５ｂの振動を抑制することができる。
【００５１】
なお、上記実施形態は以下のように変更してもよい。以下の実施形態では、前記本実施形態と異なる構成付近のみを部分的に図示するが、省略された構成は本実施形態と同様である。
【００５２】
・前記本実施形態において、図１１に示すように、前記外側保持リップ１５ｌに代えて押圧接触部としての突部１５ｓを形成し、この突部１５ｓの先端部に粗面１５ｔを形成するようにしてもよい。この別例では、突部１５ｓの粗面１５ｔが内壁面２８に押圧接触されるので、外側壁部１５ｃを溝部２５内の所定位置に安定して保持することができる。
【００５３】
・前記本実施形態において、図１２に示すように、前記内側保持リップ１５ｍに代えて、図１１で述べた突部１５ｓ及び粗面１５ｔを形成するようにしてもよい。
【００５４】
・前記本実施形態において、図１３に示すように外側保持リップ１５ｌの指向方向を離脱阻止突部１５ｋから離れるように変向してもよい。この別例では、外側保持リップ１５ｌを最初から湾曲させてその先端部が内壁面２８と直交する方向に押圧接触することにより、外側壁部１５ｃを取付位置に安定して保持することができる。
【００５５】
・図示しないが、車両のリヤドアのガラスランに具体化してもよい。
【００５６】
【発明の効果】
以上詳述したように、請求項１〜４記載の発明は、ウインドウフレームに対するガラスランの取付作業を容易に行うことができるとともに、取付状態を安定して保持することができる。
【００５７】
請求項１記載の発明は、溝部の内壁面に外側及び内側の保持リップが弾性変形して押圧接触されるので、本体部と溝部の製造及び取付誤差を吸収して取付作業を容易に行うことができる。また、前記本体部の回動嵌入動作時に車外側の屈曲部と底壁面との間に隙間が設けられているので、外側壁部の外端縁に設けた係止部をインドウフレームの車外側壁端縁に適正に係止することができる。さらに、離脱阻止突部と、溝部の車外側の内壁面に設けた係止段部との間に間隙が設定されているので、ガラスラン及び溝部の製造及び組み付け上の寸法誤差があっても、本体部を回動して溝部に嵌入する際、係止段部に離脱阻止突部が干渉しないので、その取付作業を容易に行うことができる。
【００５９】
請求項２記載の発明は、少なくとも外側保持リップの先端部に粗面が形成されているので、溝部の車外側の内壁面に対する外側保持リップの接触面の摩擦抵抗力を高めて滑動を防止することができる。
【００６１】

BACKGROUND OF THE INVENTION
The present invention relates to a glass run mounting structure attached to a window frame formed on a door of a vehicle.
[0002]
[Prior art]
The front door of the vehicle is provided with a window frame at the top of the door body, and a glass run having a channel shape is fitted and locked in a groove formed on the inner peripheral edge of the window frame. While guiding the raising and lowering of the window glass, the interior and exterior of the vehicle are sealed.
[0003]
The glass run includes a bottom wall portion as a main body portion, an outer wall portion located outside the vehicle, and an inner wall portion located inside the vehicle. The heights of the inner and outer side wall portions are substantially the same or the inner wall portion is formed slightly higher than the outer wall portion.
[0004]
[Problems to be solved by the invention]
Recently, in order to improve the appearance of the door, a glass run in which the height of the inner wall portion is set to 2 to 4 times the height of the outer wall portion has been used. The structure for attaching the glass run to the window frame will be described with reference to FIG.
[0005]
FIG. 14 shows a vertical cross section of the horizontal frame portion of the window frame 13. A body portion 15 a that forms a channel shape of the glass run 15 is fitted and locked in the groove portion 25 provided in the window frame 13. The main body portion 15a includes a bottom wall portion 15b, an outer wall portion 15c, and an inner wall portion 15d. Glass seal portions 15h and 15i are formed on the outer wall portion 15c and the inner wall portion 15d, and slides on the window glass 16. invite. The outer wall 15c is locked to a locking portion 15j that is locked to an outer edge 26a of a folded portion 26 provided on an inner wall surface of the groove 25 on the vehicle outer side, and to an inner edge 26b of the folded portion 26. A separation preventing projection 15k is formed.
[0006]
An extended inner wall portion 15g is formed integrally with the inner wall portion 15d, and a locked projection 15p formed on the periphery thereof is locked so as to get over the locking projection 31 of the window frame 13. . Further, the push-up holding lip 15 o is pressed against the position restricting surface 30 of the window frame 13, and the shielding lip 15 q is in contact with the locking projection 31. The height H2 of the extended inner wall portion 15g from the bottom wall portion 15b is about three times the height H1 of the outer wall portion 15c.
[0007]
As shown by a two-dot chain line in FIG. 14, when the glass run 15 does not have the extended inner wall portion 15 g, the push-up holding lip 15 o and the shielding lip 15 q provided at the edge of the inner wall portion 15 d are attached to the window frame 13. Positioning and holding are performed in a configuration that engages with the position regulating surface 30. For this reason, there is an attachment method in which the main body portion 15a of the glass run 15 is linearly moved from below to the groove portion 25 of the window frame 13 so as to be fitted and locked, and then the push-up holding lip 15o is locked to the position regulating surface 30. It is taken. However, in the method of inserting by moving linearly, the outer wall portion 15c and the inner wall portion 15d are pressed toward each other toward the glass seal portions 15h and 15i, so that the insertion operation is not smoothly performed. There is a problem.
[0008]
On the other hand, when the inner wall portion 15d has the extended inner wall portion 15g, a locked protrusion 15p is provided between the push-up holding lip 15o and the shielding lip 15q, and the locked protrusion 15p is the locking protrusion. It is necessary to adopt a structure that is held so as to get over 31. For this reason, the distance L from the outer surface of the shielding lip 15q to the push-up holding lip 15o becomes longer. Therefore, when the glass run 15 is linearly moved and fitted into the groove 25, the inner wall 15d and the extended inner wall 15g are greatly inclined toward the vehicle exterior, whereas the outer wall 15c is inclined toward the vehicle interior. As a result, there arises a problem that the glass seal portions 15h and 15i interfere with each other and the insertion operation is very troublesome.
[0009]
The object of the present invention is to solve the problems existing in the above-described technology, and to easily attach the glass run to the window frame, and to attach the glass run capable of stably holding the attached state. To provide a structure.

A shielding lip 15r that shields the molding 23 is formed on the locking portion 15j. The locking portion 15j and the shielding lip 15r are shielded by a frame garnish 24A.
[0031]
Since the second extrusion molding part 17b is moved up and down without the window glass 16 entering and exiting the main body part 15a, the glass sealing part 15h is directed in the direction opposite to the direction of the glass sealing part 15i, that is, outward. Has been.
[0032]
FIG. 9 shows an attachment structure of the third extruded portion 17 c of the glass run 15 to the vertical frame portion on the rear side of the window frame 13.
The attachment structure of the third extrusion molding part 17c is basically the same as the attachment structure of the second extrusion molding part 17b shown in FIG. However, the configuration in which the locking portion 15j is locked to the molding 23 and the outer holding lip 15l also functions as the separation preventing projection 15k is different.
[0033]
FIG. 10 shows a mounting structure of the third extrusion molding portion 17c below the belt line. In the glass run 15 of this portion, the glass seal portion 15h, the shielding lip 15q, the locked protrusion 15p, the push-up holding lip 15o, etc. are omitted because they are housed inside the door body 12.
[0034]
Next, a method for attaching the glass run 15 to the door body 12 and the window frame 13 will be described.
The outline of the attaching operation of the first to third extrusion molding parts 17a to 17c constituting the glass run 15 shown in FIG. 7 will be described. The second mold molding part 18b is replaced with the upper rear end part of the window opening 14 of FIG. Start by attaching to. Next, the first extrusion molding portion 17a is continuously fitted into the groove portion 25 of the window frame 13 from the rear end portion to the front end portion. Further, the first mold forming portion 18a is fitted into the groove portion 25, and the mounting operation of the second extrusion forming portion 17b is performed from the upper end portion toward the lower end portion. Then, the attachment work of the 3rd extrusion molding part 17c is performed toward a lower end part from an upper end part.
[0035]
Therefore, the attachment work of the first extrusion molding portion 17a will be described. The main body portion 15a is deformed from the expanded state shown in FIG. In this state, as shown in FIG. 4, the main body portion 15a of the first extruded portion 17a enters the groove portion 25 of the window frame 13 in an inclined state, and the locking portion 15j is locked to the outer edge 26a of the folded portion 26. To do.
[0036]
When the extended inner wall portion 15g is pushed upward, the main body portion 15a is rotated in the clockwise direction in FIG. 4 about the locking portion 15j (outer end edge 26a). By this turning operation, the inner holding lip 15m is pressed against the inner wall surface 29 of the groove 25, and the outer holding lip 151 is brought closer to the inner wall surface 28.
[0037]
As shown in FIG. 5, when the body portion 15a is rotated until the bent portion 15f on the vehicle inner side is pressed against the bottom wall surface 27 of the groove portion 25, the outer holding lip 151 and the inner holding lip 15m are compressed into an arc shape. While being curved, the shielding lip 15n is brought into contact with the bottom wall surface 27.
[0038]
Next, when the extended inner wall 15g is pressed toward the vehicle inner side as shown by the arrow in FIG. 5, the push-up holding lip 15o and the locked protrusion 15p are elastically deformed and get over the locking protrusion 31 to the vehicle inner side. As shown in FIG. 1, the push-up holding lip 15 o is pressed and brought into contact with the position regulating surface 30, and the locked protrusion 15 p is locked to the locking protrusion 31. Further, the shielding lip 15q is pressed against the outer surface of the locking projection 31. In this state, the extension inner wall 15g and the inner wall 15d are urged upward by the compression reaction force of the push-up holding lip 15o, so that the main body 15a is held at a predetermined position in the groove 25.
[0039]
As shown in FIGS. 8 and 9, the second extrusion molding portion 17 b and the third extrusion molding portion 17 c of the glass run 15 are attached without the extended inner wall portion 15 g, so that the main body portion 15 a is linearly moved to the groove portion 25. Then, the push-up holding lip 15o and the locked protrusion 15p are moved to the vehicle inner side of the locking protrusion 31. Instead of this insertion operation, an insertion operation similar to the rotation type insertion operation described above may be performed.
[0040]
According to the mounting structure of the glass run 15 of the above embodiment, the following characteristics can be obtained.
(1) In the above embodiment, the locking portion 15j provided on the outer wall portion 15c of the glass run 15 is locked to the outer edge 26a of the folded portion 26 of the window frame 13, and the locking portion 15j is the center. The glass run 15 was rotated and attached to the groove 25. For this reason, even if the inner wall portion 15d of the glass run 15 has the extended inner wall portion 15g, the mounting operation can be performed smoothly.
[0041]
Although the horizontal distance L from the outer surface of the shielding lip 15q to the push-up holding lip 15o is large, there is no hindrance to the above-described turning operation of the main body portion 15a in FIGS.
[0042]
(2) In the above-described embodiment, the outer holding lip 15l and the inner holding lip 15m are formed at the base end portions of the outer wall portion 15c and the inner wall portion 15d, and both the lips 15l and 15m are elastically deformed to form both inner and outer grooves 25. The wall surfaces 28 and 29 were pressed and contacted. Therefore, the bottom wall portion 15b of the main body portion 15a can be held at a predetermined position by the elastic force of both lips 15l and 15m, the pressing contact of the locking portion 15j against the outer edge 26a can be stably held, and the outer edge It is possible to prevent a harmful gap from being generated between 26a and the locking portion 15j.
[0043]
(3) In the above-described embodiment, in the process of turning the main body part 15a and fitting it into the groove part 25, the outer holding lip 151 is compressed and deformed into an arcuate shape whose cross section is displaced downward from the flat shape toward the tip. It was comprised so that it might press-contact to. For this reason, as shown in FIG. 2, the outer holding lip 15l exhibits the function of lifting the outer wall portion 15c, and the generation of the harmful gap after the completion of the mounting can be prevented. The reason for this will be described below.
[0044]
The tip of the rubber outer holding lip 15l moves downward from the point P1 first contacting the inner wall 28 which is the back surface of the molding 23 having a high surface roughness against the frictional resistance. Then, at the final contact point P2, the outer holding lip 15l is curved in an arc shape. Depending on the amount of elastic deformation of the outer holding lip 15l, a pressing force F1 acts diagonally downward on the inner wall surface 28 of the groove 25 as shown in FIG. Due to the pressing force F1 and the friction coefficient of the molding 23 and the outer holding lip 15l, the tip end portion of the outer holding lip 15l receives a large frictional resistance at the final contact point P2, so that downward sliding is prevented.
[0045]
On the other hand, since the outer holding lip 151 receives frictional resistance until it is moved from the contact point P1 to the final contact point P2, the outer holding lip 15l itself is compressed into an arc shape. In accordance with the amount of compression, the outer holding lip 15l further increases the pressing force F1 obliquely downward via the final contact point P2, as shown in FIG. Accordingly, the outer wall portion 15c is lifted upward by the vertical component F2a of the reaction force F2 of the pressing force F1, and the locking portion 15j can be pressed into contact with the outer edge 26a, thereby preventing the generation of the harmful gap. can do.
[0046]
(4) In the above-described embodiment, the inner holding lip 15m is provided on the proximal outer surface of the inner wall portion 15d in correspondence with the bottom wall portion 15b, and the inner holding lip 15m is pressed against the inner wall surface 29 of the groove portion 25. did. The inner holding lip 15m is curved in a downward arc shape like the outer holding lip 151 and is pressed against the inner wall surface 29 of the groove 25 by the pressing force F3. For this reason, an obliquely upward reaction force F4 also acts at the contact point P3, the inner wall portion 15d is lifted upward by the vertical component F4a of the reaction force F4, and the inner holding lip 15m is stabilized at a predetermined position. Retained.
[0047]
The contact point P3 of the inner holding lip 15m is that the inner wall 15d and the extended inner wall 15g are lifted upward when the push-up holding lip 15o and the locked protrusion 15p get over the locking protrusion 31. The bent portion 15f is temporarily compressed and pulled up to the maximum height. Thereafter, even if the compression of the bent portion 15f is released, the contact point P3 is not moved downward by the frictional resistance but is held at a predetermined position. Therefore, the inner holding lip 15m is compressed toward the contact point P3, and the same function as the outer holding lip 15l is exhibited.
[0048]
The horizontal component F4b of the reaction force F4 described above is balanced against the horizontal component F2b of the reaction force F2, the bottom wall portion 15b is sandwiched from the inside and outside of the vehicle, and the bottom wall portion 15b is fixedly attached. Holds in place stably.
[0049]
(5) In the above-described embodiment, the separation preventing projection 15k is formed on the outer wall portion 15c of the main body portion 15a of the glass run 15, and the separation preventing projection 15k and the inner end edge 26b of the folded portion 26 are interposed between the separation preventing projection 15k. The first gap G1 was formed. Therefore, even if there is a manufacturing dimensional error in the interval W between the locking portion 15j and the separation preventing projection 15k and the formation width D of the folded portion 26, the main body portion 15a is rotated and fitted into the groove portion 25. At this time, since the separation preventing projection 15k does not interfere with the folded portion 26, the fitting operation can be performed smoothly.
