Description

【０００１】
【発明の属する技術分野】
本発明は車両の乗降口を開閉するドア、特にスライドドアの開放位置を規制する車両のドア開閉装置に関する。
【０００２】
【従来の技術】
一般にワゴン車等は、車室の前後中間位置にセカンドシートが設置され、車室の後方位置にサードシートが設置されており、上記セカンドシート横の車体側部に設けられたスライドドアにより開閉される乗降口からセカンドシートおよびサードシートに着座する乗員を乗り降りさせるようにしている。ところで、上記サードシートへ乗員が乗降する場合、セカンドシートを前方へ移動させ、セカンドシートの後方にセカンドシートと上記乗降口後縁との間に乗員が通れる間隙を形成しなければならず乗降が難儀である。そこで近時、サードシートの乗員の乗降性を向上するため、セカンドシートを前方へ移動させることなく乗降できるように上記乗降口を後方へ拡大し、セカンドシートと乗降口後縁との間の上記間隙を確保するように乗降口を大型化する傾向がある。
【０００３】
しかしながら、乗降口を大型にした分、これを開閉するスライドドアも大型となり、スライドドアを開閉する際にドアの開閉ストロークが長くなるうえ、ドアの開閉操作が重くなるという問題が生じる。特に上記セカンドシートにのみ乗員が乗り降りする場合に必要以上にドアが開くことになり都合がよくない。そこで、スライドドアの開放時に、スライドドアを全開位置よりも手前の中間位置に止める中間ストッパ機構を付設することが考えられている。
【０００４】
従来のスライドドアの中間ストッパ機構として、図９、図１０に示すように、スライドドア１Ａのドア窓１１のウィンドウレギュレータに付設されてドア窓１１の開閉動作と連動するコントロール機構７と、スライドドア１Ａのロアローラー１０の支持ステーに付設され、コントロール機構７と連動して係合レバー８０を作動位置と非作動位置とに切換え可能な作動機構８とで構成されたものがある（特開平１１−２２７４６３号）。中間ストッパ機構はドア窓１１が所定の位置まで開くとコントロール機構７が作動し、これにより作動機構８の係合レバー８０が作動して車内側へ突出する（作動位置）。この状態でスライドドア１Ａを開き、スライドドア１Ａが全開位置よりも手前の中間位置に到達したときに、上記係合レバー８０が車体に設けられた段部９に衝き当たり、これ以上にスライドドア１が開かないようにしている。これは誤って開いたドア窓１１に手腕等が差し込まれた状態でスライドドア１Ａを開放しても、手腕がドア窓１１の窓枠前縁と乗降口２の開口後縁Ｐ２（後部ピラー）とに挟まれないようにするもので、乗降口を大型にしたときの操作性を向上するものではない。図９のＦはフロントドア、Ｗはクォーターウィンドである。
【０００５】
また、従来の中間ストッパ機構では、開放方向へ移動する係合レバー８０の先端を段部９に衝き当ててスライドドアを上記中間位置に止めるようにしているので、下り坂では不意にスライドドアが閉じ方向へ戻ってしまう。
【０００６】
【発明が解決しようとする課題】
そこで本発明は、スライドドアを開放操作する操作者により、必要に応じて、スライドドアを全開位置まで開放させたり、または全開位置よりも手前の中間位置まで開放させてその位置で保持させるように使い分けることができ、かつドアの開閉操作性が良好な車両のドア開閉装置を提供することを課題としてなされたものである。
【０００７】
【課題を解決するための手段】
本発明は、車両の乗降口を開閉するスライドドアと車体との間に、第１のセット状態と第２のセット状態とに切換え可能で、上記第１のセット状態で上記スライドドアを開くと、スライドドアが全開位置まで開放するのを許容し、上記第２のセット状態でスライドドアを開くと、スライドドアを全開位置よりも手前の中間位置で停止させるとともにその位置で保持する中間ストッパ機構を設け、スライドドアを開閉する操作者による操作で上記中間ストッパ機構を上記第１のセット状態および上記第２のセット状態に切換え操作する切換え手段を設ける（請求項１）。スライドドアを開閉する操作者が切換え手段を操作して中間ストッパ機構を第１のセット状態または第２のセット状態とすることで、スライドドアを開くときに、スライドドアを全開位置まで開いたり、または中間位置で止めたりすることができる。従って、例えば車室のセカンドシートへ乗降する場合と、セカンドシートとともにサードシートに乗降する場合とでスライドドアの開度を選ぶことができる。
【０００８】
上記スライドドアは、該ドアを全閉位置で車体へロックするロック機構と、該ロック機構のロックを解除するためのドアハンドルとを備えており、上記切換え手段は上記ドアハンドルを含み、該ドアハンドルにより操作可能とする（請求項２）。中間ストッパ機構を操作するための専用の操作部材等が不要で構造を簡素にでき、操作性も良好である。
【０００９】上記中間ストッパ機構は、スライドドア側に移動可能に設けられたドア側係合部材と、上記車体側に設けられた車体側係合部材とを備え、上記切換え手段により上記第１のセット状態で上記ドア側係合部材を上記車体側係合部材と係合しない非係合位置に位置させ、上記第２のセット状態で上記ドア側係合部材を上記車体側係合部材と係合する係合位置に位置させるようになし、上記切換え手段は、上記ドア側係合部材を上記係合位置または上記非係合位置に付勢する付勢部材を備え、上記ドアハンドルの操作により上記ドア側係合部材を上記付勢力に抗して上記非係合位置または上記係合位置へ移動させるようにする（請求項３）。ドア側係合部材と車体側係合部材とを係合せしめてスライドドアを中間位置で停止するようにし、かつドア側係合部材は付勢部材の付勢力とドアハンドルの操作力により第１および第２のセット状態に切り換えるようにしたのでドア開閉装置の構造が簡素ですむ。
【００１０】
上記ドア側係合部材は、上記スライドドアのスライドローラーを支持するステー部材に設けられ、上記係合位置と上記非係合位置とに移動可能な作動レバーを備え、上記車体側係合部材は、上記スライドローラーを転動案内する車体のスライドレールの外壁に沿って設られ、上記作動レバーを上記係合位置として上記スライドドアを開いたときに、上記作動レバーのレバー端を摺動案内する第１のガイド面と、第１のガイド面に設けられて上記レバー端を係脱可能に嵌合する凹状の嵌合溝と、上記作動レバーを上記非係合位置としてスライドドアを開いたときに、上記作動レバーのレバー端を摺動案内して上記嵌合溝を回避せしめる第２のガイド面と、スライドドアを全開位置から閉じるときに、上記作動レバーのレバー端を摺動案内して上記嵌合溝を回避せしめる第３のガイド面とを備えるようにする（請求項４）。第２のセット状態においてドア側係合部材の作動レバーのレバー端を車体側係合部材の断面凹状の嵌合溝に嵌合せしめて、スライドドアを中間位置で止めるようにしたので、スライドドアを確実に中間位置で保持することができ、下り坂等でもスライドドアが閉じ方向へ戻らない。かつ第１のセット状態でスライドドアを全開位置へ開くときや全開位置から閉じるときに、作動レバーが嵌合溝に嵌入することがなくスライドドアを中間位置でいちいち止めずにすむので操作性がよい。
【００１１】
【発明の実施の形態】
本発明の車両のドア開閉装置の第１の実施形態を図１ないし図６に基づいて説明する。図１に示すように、車体の側面には車室後部のセカンドシートおよびサードシートの乗員が乗り降りする大型の乗降口２が設けてあり、リヤドアであるスライドドア１により開閉される。スライドドア１は、ドア前縁の上端および下端に設けたアッパローラー１０ａおよびロアローラー１０ｂ、ドア後端縁の上下中間に設けたセンタローラー１０ｃをそれぞれ、乗降口２の開口上縁に沿うアッパレール２１ａ、開口下縁のロアレール２１ｂおよび乗降口２後方の車体側面のクォーターウィンドＷの下縁に沿うセンタレール２１ｃに転動自在に係合してスライド移動可能に設けてある。
【００１２】
スライドドア１にはドア前縁に、乗降口２の開口前縁の中間ピラーＰ１に設けたストライカ５０ａと係脱可能に係合するフロントロック５ａが設けてあり、またドア後端縁に、乗降口２の開口後縁の後部ピラーＰ２に設けたストライカ５０ｂと係脱可能に係合するリヤロック５ｂが設けてある。両ロック機構５ａ，５ｂは、スライドドア１が乗降口２を閉鎖した全閉位置で、乗降口２の前後のストライカ５０ａ，５０ｂにロックする。フロントロック５ａおよびリヤロック５ｂは、スライドドア１のアウトサイドのドアハンドル６およびインサイドのドアハンドル（図略）の操作で作動するドアリモコン機構６０と連結ワイヤ６１ａ，６１ｂにより連結され、ハンドル操作でロックを解除するようにしてある。図中、１１はドア窓、Ｆはフロントドアである。
【００１３】
スライドドア１の下部前端と、乗降口２の開口下縁の中間位置には、スライドドア１を開くときに、必要に応じてスライドドア１を全開位置（図１のＺ位置）よりも手前の中間位置（図１のＹ位置）で停止させるとともにその位置で保持せしめるための中間ストッパ機構を構成するドア側の係合部材３と車体側の係合部材４とが設けてある。
【００１４】
図２および図３に示すように、スライドドア１の下部前端には、車体側へ向けほぼ水平に突出し、ブラケット１０１を介して複数の水平ローラー１０２と垂直ローラー１０３が設けられた上記ロアローラー１０ｂを支持する金属厚板からなるステー１２が設けてあり、これに上記係合部材３が付設してある。係合部材３は金属片からなる作動レバー３０を備え、作動レバー３０はその基端がステー１２の先端付近に支軸３１より水平方向回動自在に支持せしめてある。
【００１５】
作動レバー３０の回動範囲は、作動レバー３０をロアレール２１ｂ側へ回動し、レール側のレバー側縁をステー１２に設けた一方のストッパ１３に当接してレバー端をロアレール２１ｂに近接せしめた回動位置Ｒと、スライドドア１側へ回動し、ドア側のレバー側縁をステー１２に設けた他方のストッパ１４に当接してレバー端をロアレール２１ｂから離間せしめた回動位置Ｔとの間の範囲に設定してある。作動レバー３０は、支軸３１まわりに設けられて一端をステー１２に係止するとともに他端を作動レバー３０の上記ドア側のレバー側縁に係止せしめたコイル状のバネ部材３２によりレール側の回動位置Ｒ方向へ付勢されている。
【００１６】
作動レバー３０のレバー端には上方へほぼ垂直に突出する円柱状のピン３３が突設してある。ピン３３は作動レバー３０がレール側の回動位置Ｒのときに、ロアレール２１ｂの車外側の外壁２１０に近接対向するように立設してある。
【００１７】
作動レバー３０には、長手方向中間位置のドア側のレバー側縁に設けた連結部３４に連結ワイヤ６２の一方の端末が連結してあり、作動レバー３０は、図１に示すように、連結ワイヤ６２を介してドアハンドル６のドアリモコン機構６０と連結され、ドアハンドル６の操作と連動するようにしてある。図２に示すように、作動レバー３０は、ドアハンドル６が操作されていないときにはレール側の回動位置Ｒに位置し、ドアハンドル６が操作されると連結ワイヤ６２によりドア側へ引っ張られて回動し、上記回動範囲（回動位置Ｒと回動位置Ｔとの間）のほぼ中間の回動位置Ｓへ回動する。
【００１８】
車体側の係合部材４は、上記作動レバー３０のピン３３に対応して、ロアレール２１ｂの車外側の外壁２１０の前後方向後方寄りの位置（図１）に設けてある。図２および図３に示すように、係合部材４は、ロアレール２１ｂの上面にベースプレート４０を固着し、ロアレール２１ｂよりもドア側へ張り出したベースプレート４０のドア側下半面に、ロアレール２１ｂの外壁２１０に沿って延び、作動レバー３０が回動位置Ｒのときにそのピン３３を摺動案内する第１のガイド面４１を備えた合成樹脂の第１の摺動部材４２が固着してある。また上記下半面には、第１の摺動部材４２よりもドア側の位置で第１の摺動部材４２と間隔をおいて並設され、作動レバー３０が回動位置Ｓのときにそのピン３３を摺動案内する第２のガイド面４３を備えた合成樹脂の第２の摺動部材４４が固着してある。第１および第２の摺動部材４２，４４の間隔はピン３３の直径よりも広くしてあり、両摺動部材４２，４４間にはピン３３が通過可能な通路を形成している。
【００１９】
第１のガイド面４１には、ロアレール２１ｂの外壁２１０からドア側へ向かって緩やかに斜め方向に延びる前部傾斜面を経て外壁２１０とほぼ平行な中間面が設けてあり、該中間面にはピン３３を係脱可能に嵌合する嵌合溝４５が形成してある。嵌合溝４５は前後方向に長めに形成してあり、溝内の前後の端部および中央位置に深い凹状部４５１が形成してあり、各凹状部４５１間には山形の凸状部４５２が形成してある。嵌合溝４５の前端および後端の溝壁は上記中間面に対してほぼ直交方向に変位するように形成してある。第１のガイド面４１には上記中間面の後端から外壁２１０へ向かって緩やかに斜め方向に延びる後部傾斜面を備えている。
【００２０】
第２の摺動部材４４は第１の摺動部材４２よりも短くしてあり、第２の摺動部材４４の後端末が第１のガイド面４１の嵌合溝４５の後端に対応する位置としてある。第２の摺動部材４４は上記通路側の側壁面がロアレール２１ｂの外壁２１０とほぼ平行な上記第２のガイド面４３をなし、第２のガイド面４３の前端は上記通路側へ向かって斜めに傾斜するテーパー面としてある。第２の摺動部材４４のドア側の側壁面には、作動レバー３０を回動位置Ｔとしてピン３３を摺動案内する外壁２１０とほぼ平行な第３のガイド面４６が形成してある。
【００２１】
図２に示すように、第３のガイド面４６の後端面は第１のガイド面４１の上記後部傾斜面へ向かって斜めに延び、上記後部傾斜面とほぼ同一の傾斜とした傾斜面をなし、第３のガイド面４６の後端には、上記通路の後端開口を開閉する開閉板４７が付設してあり、開閉板４７はその基端が支軸４７０により上記傾斜面の中間部に水平方向回動自在に支持され、上記両傾斜面間に架けわたして上記通路の後端開口を閉じ、支軸４７０を中心にドア側へ水平回動して上記通路の後端開口を開く。開閉板４７はバネ部材４８により上記通路を閉じる方向へ回動付勢されている。
【００２２】
図４ないし図６に基づいて第１の実施形態によるスライドドア１の開閉作動を説明する。スライドドア１を全閉位置から中間位置Ｙまで開く場合には、まず全閉位置でドアハンドル６を操作してドアリモコン機構６０を作動させてフロントロック５ａおよびリヤロック５ｂのロックを解除させる。図４に示すように、上記ロックを解除した後に、上記ドアハンドル６の操作を取り止めるとドア側係合部材３の作動レバー３０がバネ部材３２の付勢力により回動位置Ｒとなり、車体側係合部材４の嵌合溝４５へ嵌入可能な係合位置（第２のセット状態）となる。
【００２３】
この第２のセット状態でスライドドア１を後方へ移動させると、ドアと一体にロアレール２１ｂの外壁２１０に沿って後方へ移動する作動レバー３０のピン３３が車体側の係合部材４の第１のガイド面４１の前部傾斜面に当接し、第１のガイド面４１に沿って摺動案内されて第１および第２の摺動部材４１，４４間の上記通路内へ進入する。作動レバー３０は、ピン３３が第１のガイド面４１の前部傾斜面から中間面前端にかけて摺動するにつれてバネ部材３２の付勢力に抗してドア側へ回動する。作動レバー３０は、ピン３３が嵌合溝４５の前端位置に至ると、上記付勢力によってレール側へ回動し、ピン３３が嵌合溝４５前端の凹状部４５１へ嵌入される。ピン３３が前側の凹状部４５１へ嵌入されると、スライドドア１の移動に対して、ピン３３が上記凹状部４５１の後方の凸部４５２の前側傾斜面に当たり、スライドドア１の移動が阻止され、スライドドア１は上記中間位置Ｙで停止する。
【００２４】
嵌合溝４５は、溝内に複数の凹状部４５１と複数の凸状部４５２が形成してあるので、スライドドア１の後方への移動力が大きく上記前端の凹状部４５１へ嵌入されたピン３が凸部４５２を乗り越えたとしても、中央または後端のいずれかの凹状部４５１にピン３３が嵌入することでスライドドア１は停止する。尚、ピン３３は作動レバー３０が第２のセット状態において、嵌合溝４５の上記後端の溝壁を乗り越えることがないので、ピン３３が嵌合溝４５を通過せず確実にスライドドア１を停止することができる。
【００２５】
一方、下り坂等で、上記中間位置Ｙで止めたスライドドア１が閉じ方向へ戻ろうとしても、ピン３３が嵌合溝４５の上記前端の溝壁を乗り越えることができないのでスライドドア１の戻りが防止される。
【００２６】
スライドドア１を中間位置Ｙから全開位置Ｚへ開くときは、ドアハンドル６を操作して、作動レバー３０をドア側の回動位置Ｓへ回動し、ピン３３を嵌合溝４５から抜くとともに第２のガイド面４３に当接せしめる。そして、スライドドア１を後方へ移動させることで、ピン３３が第２のガイド面４３に沿って摺動案内されて上記通路内を後方へ移動し、通路後端の開閉板４７をバネ部材４７０の付勢力に抗して押し開き、係合部材４の後方へ抜け出す。このようにしてスライドドア１は全開位置Ｚへ移動する。
【００２７】
また、スライドドア１を中間位置Ｙから全閉位置へ戻すときは、ドアハンドル６を操作して、作動レバー３０をドア側の回動位置Ｓへ回動し、ピン３３と嵌合溝４５との嵌合を解除するとともにピン３３を第２のガイド面４３に当接せしめ、この状態でスライドドア１を前方へ移動させる。このようにしてスライドドア１を閉じる。
【００２８】
スライドドア１を全閉位置から全開位置Ｚへ開く場合には、ドアハンドル６を操作して両ロック機構５ａ，５ｂのロックを解除した後にドアハンドル６を操作し続ける。これにより、図５に示すように、ドア側係合部材３の作動レバー３０はバネ部材３２の付勢力に抗して回動位置Ｓへ回動し、車体側係合部材４の嵌合溝４５へ嵌入不可能な非係合位置（第１のセット状態）が保持される。
【００２９】
第１のセット状態でスライドドア１を後方へ移動させると、後方へ移動する作動レバー３０のピン３３が車体側係合部材４の第２のガイド面４３の前端テーパー面に当接し、若干レール側へ回動変位しつつ第２のガイド面４３に沿って後方へ摺動案内されて上記通路内を後方へ移動し、通路後端の開閉板４７を押し開き、係合部材４の後方へ抜け出る。このようにしてスライドドア１は全開位置Ｚへ開く。
【００３０】
スライドドア１を全開位置Ｚから全閉位置へ閉じる場合には、ドアハンドル６を操作する、操作しないに係わらず、スライドドア１を前方へ移動させると、前方へ移動する作動レバー３０のピン３３が車体側係合部材４の第１のガイド面４１の後部傾斜面に当接し、上記後部傾斜面および開閉板４７に沿って摺動案内されて第３のガイド面４６へ至る。作動レバー３０は、ピン３３が上記後部傾斜面および開閉板４７から第３のガイド面４６にかけて摺動するにつれてバネ部材３２の付勢力に抗してドア側の回動位置Ｔへ回動する。そしてピン３３が第３のガイド面４６の前端を通過すると、作動レバー３０は上記付勢力によってレール側へ回動して回動位置Ｒへ戻る。このようにしてスライドドア１は全閉位置へ至る。
【００３１】
第１の実施形態は、ドアハンドル６を操作してドアロックを解除した後に、ドアハンドル６の操作を取り止めることで、ドア側係合部材３が第２のセット状態となってスライドドア１を中間位置Ｙで止めることができ、ドアロックを解除した後にドアハンドル６を操作し続けることで、ドア側係合部材３が第１のセット状態となってスライドドア１を全開位置Ｚへ開くことができ、スライドドアを開閉操作する操作者は、必要に応じてスライドドア１を中間位置Ｙで止めたりまたは全開位置Ｚへ開いたり使い分けすることができる。例えば、車室後部のセカンドシートの乗員のみが乗降するときにはスライドドア１を中間位置Ｙで止めるようにすれば操作者の労力が少なくすむ。上記使い分け操作もドアハンドル６の操作ですみ操作性が良好である。
【００３２】
スライドドア１を中間位置Ｙで止る場合には、ドア側係合部材３の作動レバー３０のピン３３を車体側係合部材４の凹状の嵌合溝４５へ嵌入するようにしたので、スライドドア１は中間位置Ｙで確実に保持され、例え坂道等でもスライドドア１は移動しない。
【００３３】
ドア側係合部材３が第１のセット状態でスライドドア１を全閉位置から全開位置Ｚへ開く場合には、車体側係合部材４の第２のガイド面４３が嵌合溝４５を回避して作動レバー３０のピン３３を摺動案内するので、スライドドア１を中間位置Ｙで止めることなくスムーズに全開することができる。また、スライドドア１を全開位置Ｚから全閉位置へ閉じる場合も、第３のガイド面４６が嵌合溝４５を回避して作動レバー３０のピン３３を摺動案内するので、スライドドア１を中間位置Ｙで止めることなくスムーズに閉じることができる。
【００３４】
次に図７および図８に基づいて本発明の第２の実施形態を説明する。本実施形態の基本構造は第１の実施形態のそれとほぼ同一で、相違点を中心に説明し、図において同一部材は同一符号で表す。図７に示すように、ドア側の係合部材３の作動レバー３０は支軸３１を中心に水平方向に回動可能としてあり、ロアレール２１ｂ側へ回動してレバー端のピン３３をロアレール２１ｂに近接せしめた回動位置Ｒと、ドア側へ回動してピン３３をロアレール２１ｂから離間せしめた回動位置Ｔとの間で回動する。作動レバー３０は、図略のバネ部材によりレール側の回動位置Ｒ方向へ付勢されている。
【００３５】
作動レバー３０は、その連結部３４に連結した連結ワイヤ６２を介して図略のドアハンドルのドアリモコン機構と連結され、ドアハンドルを操作することによりドア側へ引っ張られて回動位置Ｓへ回動するようにしてある。
【００３６】
車体側の係合部材４Ａは、ロアレール２１ｂの上面にベースプレート４０を固着し、ドア側へ張り出したベースプレート４０のドア側下半面に、ロアレール２１ｂの外壁２１０と間隔をおいて並設した合成樹脂の摺動部材４２Ａが固着してある。摺動部材４２Ａは、そのドア側の側壁に作動レバー３０が回動位置Ｓのときにそのピン３３を摺動案内する第１のガイド面４１が形成してある。
【００３７】
第１のガイド面４１は、レール側からドア側へ向かって緩やかに斜め方向に延びる前部傾斜面を経て外壁２１０とほぼ平行な中間面が設けてあり、該中間面には作動レバー３０のピン３３を係脱可能に嵌合する嵌合溝４５が形成してある。嵌合溝４５は前後長が長めにしてあり、溝内には複数の深い凹状部と、各凹状部間に複数の山形の凸状部が形成してある。嵌合溝４５の前端の溝壁は第１のガイド面４１の上記中間面に対してほぼ直交方向に変位するように形成してあり、後端の溝壁はドア側へ向かう緩やかな傾斜面をなし、外壁２１０とほぼ平行な上記中間面の後端部へ連通せしめてある。
【００３８】
摺動部材４２Ａは、外壁２１０との間に、作動レバー３０のピン３３の直径よりも広幅で、ピン３３が通過可能な通路が形成してある。上記通路を形成する摺動部材４２Ａのレール側の側壁は、前半部が外壁２１０と平行な第２のガイド面４３をなし、後半部は第２のガイド面４３の後端からドア側へ向かって斜めに屈折した傾斜面状の第３のガイド面４６が形成してあり、第３のガイド面４６により上記通路の後端の通路幅は後方へ向けて漸次広げてある。
【００３９】
第２の実施形態によるスライドドアの開閉作動は、スライドドアを全閉位置から中間位置まで開く場合、ドアハンドルを操作してドアのフロントロックおよびリヤロックのロックを解除した後、上記ドアハンドルを操作し続けることで、ドア側係合部材３の作動レバー３０は回動位置Ｓへ回動した状態で保持され、車体側係合部材４Ａの嵌合溝４５へ嵌入可能な係合位置（第２のセット状態）となる。
【００４０】
第２のセット状態でスライドドアを後方へ移動させると、後方へ移動する作動レバー３０のピン３３が車体側係合部材４の第１のガイド面４１の前部傾斜面に当接しこれに沿って摺動案内される。作動レバー３０は、ピン３３が第１のガイド面４１の前部傾斜面から中間部前端にかけて摺動するにつれて上記バネ部材の付勢力に抗して回動位置Ｓから回動位置Ｔ側へ回動する。作動レバー３０は、ピン３３が嵌合溝４５の前端に至ると、上記付勢力によってレール側へ回動してピン３３が嵌合溝４５の前端の凹状部へ嵌入され、これによりスライドドアは上記中間位置Ｙで停止する。
【００４１】
スライドドアを中間位置Ｙから全開位置Ｚへ開くときは、スライドドアを後方へ強めに移動させることで、ピン３３が嵌合溝４５内を摺動してこれ乗り越え、ピン３３と嵌合溝４５との嵌合が解除されてスライドドアは全開位置Ｚへ開く。尚、作動レバー３０はピン３３が第１のガイド面４１の後端末を通過すると上記付勢力により回動位置Ｒへ回動復帰する。
【００４２】
スライドドアを全閉位置から全開位置Ｚへ開く場合には、ドアハンドルを操作してドアロックを解除した後に、ドアハンドルの操作を解除することで、図８に示すように、作動レバー３０がバネ部材３２の付勢力により回動位置Ｒへ回動復帰し、嵌合溝４５へ嵌入不可能な非係合位置（第１のセット状態）となる。
【００４３】
第１のセット状態でスライドドアを後方へ移動させると、作動レバー３０のピン３３が車体側係合部材４の上記通路内を通過して、スライドドアは全開位置Ｚへ開く。例えピン３３が上記通路内を通過中に、誤ってドアハンドルを操作しても、ピン３３が第２のガイド面４３に当接して作動レバー３０は回動せず、スライドドアをスムーズに全開位置Ｚへ開くことができる。
【００４４】
スライドドアを全開位置Ｚから全閉位置へ閉じる場合には、スライドドアを前方へ移動させると、作動レバー３０のピン３３が車体側係合部材４の上記通路内を通過し、スライドドアは全閉位置へ至る。尚、スライドドアを全開位置Ｚから前方へ移動させるときに、ドアハンドルを操作して作動レバー３０が回動位置Ｓへ回動されても、ピン３３が第３のガイド面４６に当接し、これに摺動案内されるので、作動レバー３０はレール側へ押しまわされてピン３３が上記通路へ導かれ、スライドドアをスムーズに閉じることができる。
【００４５】
第２の実施形態は、ドアハンドルを操作してドアロックを解除した後に、ドアハンドルの操作を続けることで、ドア側係合部材３が第２のセット状態となってスライドドアを中間位置Ｙで止めることができ、ドアロックを解除した後にドアハンドルの操作を取り止めることで、ドア側係合部材３が第１のセット状態となってスライドドアを全開位置Ｚへ開くことができ、上述の第１の実施形態と同様な作用効果が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a door that opens and closes a doorway of a vehicle, and more particularly to a vehicle door opening and closing device that regulates an opening position of a slide door.
[0002]
[Prior art]
In general, wagons, etc., have a second seat installed at the front and rear intermediate position of the cabin, a third seat installed at the rear position of the cabin, and are opened and closed by a slide door provided on the side of the vehicle next to the second seat. An occupant sitting on the second seat and the third seat can get on and off from the entrance. By the way, when the occupant gets on and off the third seat, the second seat must be moved forward to form a gap through which the occupant can pass between the second seat and the rear edge of the entrance and exit behind the second seat. It is difficult. Therefore, recently, in order to improve the occupancy of the occupant of the third seat, the entrance has been expanded rearward so that the second seat can be entered and exited without being moved forward, and the above-described space between the second seat and the rear edge of the entrance is removed. There is a tendency that the entrance is enlarged to secure a gap.
[0003]
However, the sliding door that opens and closes the door is also large because the doorway is enlarged, which causes a problem that the opening / closing stroke of the door becomes longer and the opening / closing operation of the door becomes slower. Particularly when the occupant gets on and off the second seat only, the door is opened more than necessary, which is not convenient. Therefore, it has been considered to provide an intermediate stopper mechanism for stopping the slide door at an intermediate position before the fully open position when the slide door is opened.
[0004]
As shown in FIGS. 9 and 10, a control mechanism 7 attached to a window regulator of a door window 11 of a slide door 1A and interlocked with opening and closing operations of the door window 11, as an intermediate stopper mechanism of a conventional slide door, as shown in FIGS. There is an operating mechanism 8 attached to a support stay of the lower roller 10 of 1A and capable of switching an engaging lever 80 between an operating position and a non-operating position in conjunction with a control mechanism 7 (Japanese Patent Application Laid-Open No. Hei 11-1999). -227463). When the door window 11 is opened to a predetermined position, the control mechanism 7 operates the intermediate stopper mechanism, whereby the engaging lever 80 of the operating mechanism 8 is operated to protrude toward the inside of the vehicle (operating position). In this state, the slide door 1A is opened, and when the slide door 1A reaches an intermediate position before the fully open position, the engagement lever 80 hits the step 9 provided on the vehicle body, and the slide door 1A is further extended. One keeps it from opening. This is because, even if the sliding door 1A is opened in a state in which a hand or the like is inserted into the opened door window 11 by mistake, the hand or the hand is moved to the front edge of the window frame of the door window 11 and the rear edge P2 (rear pillar) of the entrance 2 of the doorway. It does not improve operability when the entrance is enlarged. In FIG. 9, F is a front door, and W is a quarter window.
[0005]
Further, in the conventional intermediate stopper mechanism, the tip of the engaging lever 80 that moves in the opening direction hits the step portion 9 so as to stop the slide door at the intermediate position. It returns to the closing direction.
[0006]
[Problems to be solved by the invention]
Accordingly, the present invention provides an operator opening the slide door, as necessary, to open the slide door to the fully open position, or to open the slide door to an intermediate position before the fully open position and hold the slide door at that position.

The first guide surface 41 is provided with a rear inclined surface gently and obliquely extending from the rear end of the intermediate surface toward the outer wall 210.
[0020]
The second sliding member 44 is shorter than the first sliding member 42, and the rear end of the second sliding member 44 corresponds to the rear end of the fitting groove 45 of the first guide surface 41. As a position. The second sliding member 44 forms the second guide surface 43 whose side wall surface on the passage side is substantially parallel to the outer wall 210 of the lower rail 21b, and the front end of the second guide surface 43 is inclined toward the passage side. It is a tapered surface that is inclined. On the side wall surface on the door side of the second sliding member 44, a third guide surface 46 substantially parallel to the outer wall 210 that slides and guides the pin 33 with the operating lever 30 at the rotation position T is formed.
[0021]
As shown in FIG. 2, the rear end surface of the third guide surface 46 extends obliquely toward the rear inclined surface of the first guide surface 41, and forms an inclined surface having substantially the same inclination as the rear inclined surface. At the rear end of the third guide surface 46, an opening / closing plate 47 for opening and closing the rear end opening of the passage is provided, and the base end of the opening / closing plate 47 is provided at a middle portion of the inclined surface by a support shaft 470. It is supported so as to be rotatable in the horizontal direction, is closed between the two inclined surfaces, closes the rear end opening of the passage, and is horizontally turned around the support shaft 470 toward the door to open the rear end opening of the passage. The opening / closing plate 47 is urged by a spring member 48 to rotate in a direction to close the passage.
[0022]
An opening and closing operation of the slide door 1 according to the first embodiment will be described with reference to FIGS. When the slide door 1 is opened from the fully closed position to the intermediate position Y, first, the door handle 6 is operated in the fully closed position to operate the door remote control mechanism 60 to unlock the front lock 5a and the rear lock 5b. As shown in FIG. 4, when the operation of the door handle 6 is stopped after the lock is released, the operating lever 30 of the door-side engaging member 3 is turned to the rotation position R by the urging force of the spring member 32, and The engagement position (the second set state) at which the engagement member 4 can be fitted into the engagement groove 45 is obtained.
[0023]
When the slide door 1 is moved rearward in the second set state, the pin 33 of the operating lever 30 that moves rearward along the outer wall 210 of the lower rail 21b integrally with the door is moved to the first position of the engagement member 4 on the vehicle body side. Abuts on the front inclined surface of the first guide surface 41, slides along the first guide surface 41, and enters the passage between the first and second sliding members 41 and 44. The operation lever 30 rotates toward the door against the urging force of the spring member 32 as the pin 33 slides from the front inclined surface of the first guide surface 41 to the front end of the intermediate surface. When the pin 33 reaches the front end position of the fitting groove 45, the operating lever 30 rotates toward the rail by the urging force, and the pin 33 is fitted into the concave portion 451 at the front end of the fitting groove 45. When the pin 33 is fitted into the concave portion 451 on the front side, the pin 33 hits the front inclined surface of the convex portion 452 behind the concave portion 451 with respect to the movement of the slide door 1, and the slide door 1 is prevented from moving. The slide door 1 stops at the intermediate position Y.
[0024]
Since the fitting groove 45 has a plurality of concave portions 451 and a plurality of convex portions 452 formed in the groove, the rearward movement force of the slide door 1 is large and the pin fitted into the concave portion 451 at the front end is provided. Even if 3 gets over the convex portion 452, the slide door 1 stops because the pin 33 fits into the concave portion 451 at either the center or the rear end. Since the pin 33 does not climb over the groove wall at the rear end of the fitting groove 45 when the operating lever 30 is in the second set state, the pin 33 does not pass through the fitting groove 45, so that the slide door 1 can be securely inserted. Can be stopped.
[0025]
On the other hand, even if the slide door 1 stopped at the intermediate position Y tries to return in the closing direction on a downhill or the like, the return of the slide door 1 is not possible because the pin 33 cannot climb over the groove wall at the front end of the fitting groove 45. Is prevented.
[0026]
When the slide door 1 is to be opened from the intermediate position Y to the fully open position Z, the door handle 6 is operated to rotate the operation lever 30 to the door-side rotation position S, pull out the pin 33 from the fitting groove 45, and It is brought into contact with the second guide surface 43. Then, by moving the slide door 1 backward, the pin 33 is slidably guided along the second guide surface 43 and moves backward in the passage, and the opening / closing plate 47 at the rear end of the passage is moved to the spring member 470. Pushes open against the urging force of (2) and comes out of the engagement member 4 rearward. Thus, the slide door 1 moves to the fully open position Z.
[0027]
When returning the sliding door 1 from the intermediate position Y to the fully closed position, the door handle 6 is operated to turn the operating lever 30 to the door-side turning position S, and the pin 33 and the fitting groove 45 Is released and the pin 33 is brought into contact with the second guide surface 43, and the slide door 1 is moved forward in this state. Thus, the slide door 1 is closed.
[0028]
When the slide door 1 is opened from the fully closed position to the fully opened position Z, the door handle 6 is operated to release the locks of both the lock mechanisms 5a and 5b, and then the door handle 6 is continuously operated. As a result, as shown in FIG. 5, the operating lever 30 of the door-side engaging member 3 is turned to the turning position S against the urging force of the spring member 32, and the fitting groove of the vehicle-body-side engaging member 4 is fitted. The non-engagement position (first set state) in which it is not possible to fit into 45 is held.
[0029]
When the slide door 1 is moved rearward in the first set state, the pin 33 of the operating lever 30 moving rearward comes into contact with the front end tapered surface of the second guide surface 43 of the vehicle body side engaging member 4, and the rail is slightly moved. While being rotationally displaced to the side, it is slid and guided rearward along the second guide surface 43, moves rearward in the passage, pushes the open / close plate 47 at the rear end of the passage, and moves rearward of the engaging member 4. Get out. Thus, the slide door 1 opens to the fully open position Z.
[0030]
When closing the slide door 1 from the fully open position Z to the fully closed position, regardless of whether the door handle 6 is operated or not, when the slide door 1 is moved forward, the pin 33 of the operating lever 30 that moves forward is moved. Abuts on the rear inclined surface of the first guide surface 41 of the vehicle body side engaging member 4, slides along the rear inclined surface and the opening / closing plate 47, and reaches the third guide surface 46. The operation lever 30 rotates to the door-side rotation position T against the urging force of the spring member 32 as the pin 33 slides from the rear inclined surface and the opening / closing plate 47 to the third guide surface 46. Then, when the pin 33 passes through the front end of the third guide surface 46, the operating lever 30 rotates toward the rail by the urging force and returns to the rotating position R. Thus, the slide door 1 reaches the fully closed position.
[0031]
In the first embodiment, after the door lock is released by operating the door handle 6, the operation of the door handle 6 is stopped, so that the door-side engaging member 3 is in the second set state and the slide door 1 is moved. The door can be stopped at the intermediate position Y, and by continuing to operate the door handle 6 after releasing the door lock, the door-side engagement member 3 is brought into the first set state, and the slide door 1 is opened to the fully open position Z. The operator who opens and closes the sliding door can stop and use the sliding door 1 at the intermediate position Y or open the sliding door 1 to the fully open position Z as needed. For example, when only the occupant of the second seat at the rear of the passenger compartment gets on and off, if the slide door 1 is stopped at the intermediate position Y, the labor of the operator can be reduced. The operability is good because only the operation of the door handle 6 is required for the above-described proper operation.
[0032]
When the slide door 1 is stopped at the intermediate position Y, the pin 33 of the operating lever 30 of the door side engaging member 3 is fitted into the concave fitting groove 45 of the vehicle body side engaging member 4, so that the slide door 1 is securely held at the intermediate position Y, and the slide door 1 does not move even on a slope or the like.
[0033]
When the sliding door 1 is opened from the fully closed position to the fully open position Z in the first set state of the door side engaging member 3, the second guide surface 43 of the vehicle body side engaging member 4 avoids the fitting groove 45. As a result, the pin 33 of the operating lever 30 is slidably guided, so that the slide door 1 can be fully opened smoothly without stopping at the intermediate position Y. Also, when the slide door 1 is closed from the fully open position Z to the fully closed position, the third guide surface 46 avoids the fitting groove 45 and slides and guides the pin 33 of the operation lever 30. It can be closed smoothly without stopping at the intermediate position Y.
[0034]
Next, a second embodiment of the present invention will be described with reference to FIGS. The basic structure of the present embodiment is almost the same as that of the first embodiment, and the description will be focused on the differences. As shown in FIG. 7, the operating lever 30 of the engagement member 3 on the door side is rotatable in the horizontal direction about the support shaft 31, and is turned to the lower rail 21b side to move the pin 33 at the lever end to the lower rail 21b. , And a rotation position T which is rotated to the door side to rotate the pin 33 away from the lower rail 21b. The operating lever 30 is urged by a spring member (not shown) in the direction of the rotation position R on the rail side.
[0035]
The operating lever 30 is connected to a door remote control mechanism of a door handle (not shown) via a connecting wire 62 connected to the connecting portion 34. The operating lever 30 is pulled toward the door side by operating the door handle and turned to the rotation position S. It works.
[0036]
The engaging member 4A on the vehicle body side is made of a synthetic resin in which the base plate 40 is fixed to the upper surface of the lower rail 21b, and which is arranged side by side with the outer wall 210 of the lower rail 21b on the lower half of the door side of the base plate 40 projecting to the door side. The sliding member 42A is fixed. The sliding member 42A has a first guide surface 41 for slidingly guiding the pin 33 when the operating lever 30 is at the rotation position S on the side wall on the door side.
[0037]
The first guide surface 41 is provided with an intermediate surface substantially parallel to the outer wall 210 via a front inclined surface extending gently and obliquely from the rail side toward the door side. A fitting groove 45 into which the pin 33 is detachably fitted is formed. The fitting groove 45 has a longer front-rear length, and a plurality of deep concave portions and a plurality of mountain-shaped convex portions are formed between the concave portions in the groove. The groove wall at the front end of the fitting groove 45 is formed so as to be displaced in a direction substantially perpendicular to the intermediate surface of the first guide surface 41, and the groove wall at the rear end is a gentle slope toward the door. And communicates with the rear end of the intermediate surface substantially parallel to the outer wall 210.
[0038]
The sliding member 42A has a passage formed between the outer wall 210 and the outer wall 210, which is wider than the diameter of the pin 33 of the operating lever 30 and through which the pin 33 can pass. The side wall on the rail side of the sliding member 42A forming the passage forms a second guide surface 43 parallel to the outer wall 210 in the front half, and the rear half faces the rear end of the second guide surface 43 toward the door. A third guide surface 46 in the form of an inclined surface bent obliquely is formed, and the width of the rear end of the passage is gradually increased rearward by the third guide surface 46.
[0039]
In the opening and closing operation of the slide door according to the second embodiment, when the slide door is opened from the fully closed position to the intermediate position, the door handle is operated to unlock the front lock and the rear lock of the door, and then the door handle is operated. By continuing the operation, the operating lever 30 of the door-side engaging member 3 is held in a state of being turned to the turning position S, and the engaging position (the second Set state).
[0040]
When the slide door is moved rearward in the second set state, the pin 33 of the operating lever 30 moving rearward abuts on the front inclined surface of the first guide surface 41 of the vehicle body side engaging member 4 and follows the same. Sliding guide. As the pin 33 slides from the front inclined surface of the first guide surface 41 to the front end of the intermediate portion, the operating lever 30 rotates from the rotation position S to the rotation position T against the urging force of the spring member. Move. When the pin 33 reaches the front end of the fitting groove 45, the operating lever 30 rotates toward the rail due to the urging force, and the pin 33 is fitted into the concave portion at the front end of the fitting groove 45. It stops at the intermediate position Y.
