Description

【０００１】
【発明の属する技術分野】
本発明は、開方向へ移動するスライドドアを中間位置で止め、かつスライドドアの上記中間位置から閉方向への移動を規制する車両用スライドドアの開位置保持装置に関する。
【０００２】
【従来の技術】
従来、自動車のスライドドアには、窓ガラスを昇降して開閉するドア窓が設けられている。この種のスライドドアは、スライドドアを開く際、スライドドアを全開位置よりも手前の中間位置で止め、これ以上に開かないようにする中間ストッパ装置が設けられている。
【０００３】
図１１に示すように、スライドドアＤには、ドア窓Ｄ１のウィンドウレギュレータに、ドア窓Ｄ１の開閉動作と連動する作動部材９０と、スライドドアＤのロアローラーＲの支持ステーに設けられ、上記作動部材９０と連動して作動位置と非作動位置とに切換え可能な中間ストッパ９１とからなる中間ストッパ装置が設置されたものがある。該中間ストッパ装置はドア窓Ｄ１が所定の位置まで開くと作動部材９０が作動し、これと連動して中間ストッパ９１が車体側へ突出するようになっている。この状態でスライドドアＤを開き、スライドドアＤが全開位置よりも手前の中間位置に到達したときに、中間ストッパ９１が車体に設けられた段状の車体側ストッパ部９２に衝き当たり、これ以上にスライドドア１が開かないようになっている（例えば、特許文献１参照。）。
【０００４】
また他の従来構造として、車体側に設けられたストライカとドア側に設けられたラッチとを係脱可能に係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ものがある。図１２に示すように、車体側には、スライドレールＳに沿うように中間ストライカ８１と、全開ストライカ８２が設けられている。スライドドア側には、ロアローラーＲの支持ステーに両ストライカ８１，８２に係脱可能なラッチ８３と、スライドドアのドア窓が所定の位置まで開くと第１のリンク８４に押圧されてラッチ８３と係合可能な位置へ移動し、中間ストライカ８１と係合したラッチ８３の一方の係合解除方向への移動を禁止してスライドドアの開方向（白矢印Ｘ）への移動を規制する中間ポール８５と、スライドドアが全開位置まで移動したときに、ラッチ８３と係合可能な位置へ移動し、全開ストライカ８２と係合したラッチ８３の他方の係合解除方向への移動を禁止してスライドドアの閉方向への移動を規制するとともに、ドアハンドルの操作で第２のリンク８６に押圧されてラッチ８３との係合を解除する全開ポール８７が設けられている（例えば、特許文献２参照。）。これによれば、ドア窓が開いたままスライドドアを開くと、中間ストライカ８１にラッチ８３が係合したとき、中間ポール８５がラッチ８３に係合して、ドア開方向へのラッチ８３と中間ストライカ８１との係合解除を禁止するのでスライドドアの中間位置から全開位置への移動が規制される。

【発明が解決しようとする課題】
しかしながら、上述のいずれの従来構造も、スライドドアの中間位置から開方向への移動は規制されるが、中間位置から閉方向への移動は規制されない。従って、車両を下り坂等に駐車したときに、スライドドアを上記中間位置へ開いても不意にスライドドアが閉方向へ戻ってしまうおそれがあった。そこで本発明は、スライドドアの中間位置から開方向への移動を規制するとともに、中間位置から閉方向への移動も規制することができる車両用スライドドアの開位置保持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、車体に設けられた車体側ストッパ部材と、スライドドアに設けられ、作動位置と非作動位置とに移動可能で、上記作動位置にある状態では、スライドドアが全開位置よりも手前の中間位置まで開くと上記車体側ストッパ部材に当接して、スライドドアが中間位置を越えて開くことを規制し、上記非作動位置にある状態では、スライドドアが全開位置まで開くことを許容するドア側ストッパ部材と、上記ドア側ストッパ部材を移動させる移動手段と、スライドドアに設けられたロック機構と、車体に設けられ、作動位置と非作動位置とに移動可能で、上記作動位置にある状態では、スライドドアが上記中間位置まで開くと、上記ロック機構と噛み合ってスライドドアを上記中間位置に保持し、上記非作動位置にある状態では、スライドドアが全開位置まで開くことを許容する中間ロック部材と、上記ロック機構の上記中間ロック部材との噛み合いを解除する操作手段と、上記ドア側ストッパ部材が上記作動位置にある状態では、スライドドアが全閉位置から上記中間位置まで開く間に、上記中間ロック部材を上記作動位置へ移動せしめる作動手段とで構成する（請求項１）。ドア側ストッパ部材が作動位置のとき、この状態でスライドドアを開くと作動手段により車体側の中間ロック部材が作動位置へ移動する。そしてスライドドアが中間位置に至ると、ドア側ストッパ部材が車体側ストッパ部材に当接し、作動位置となった中間ロック部材がドアのロック機構に噛み合い、スライドドアが中間位置を越えて開くことを規制するとともに、スライドドアが中間位置で保持される。従って下り坂等でも不意にドアが閉まることがない。操作手段によりロック機構の中間ロック部材との噛み合いを解除しドアを閉めることができる。ドア側ストッパ部材が非作動位置にある状態でスライドドアを開くと、中間ロック部材が作動せず、スライドドアを全開位置まで開くことができる。スライドドアを中間位置で止めるためのドア側ストッパ部材とは別に、スライドドアを中間位置で保持するためのロック機構が設けられているため、ロック機構にスライドドアを中間位置で止めるための衝撃が伝わり破損するのを防止できる。
【０００８】
上記作動手段は、車体に設けられ、上記ドア側ストッパ部材が上記作動位置にある状態でスライドドアが上記全閉位置から上記中間位置まで開く間に、上記ドア側ストッパ部材に押されて非作動位置から作動位置に移動する作動部材を具備しており、該作動部材の動きを上記中間ロック部材に伝えて上記中間ロック部材を上記作動位置へ移動させるように構成する（請求項２）。作動部材は、ドア側ストッパ部材を利用して中間ロック部材を移動させる構造であるから、構成部品を少なくすることができる。
【０００９】
上記作動手段は、上記中間ロック部材を上記作動位置へ付勢するロック付勢部材と、上記中間ロック部材に係合して中間ロック部材を上記非作動位置に保持する係合状態と、中間ロック部材との係合を解除する解除状態とに切換可能なロック係合部材を具備しており、スライドドアが上記中間位置よりも手前の所定の位置まで開いたとき上記ドア側ストッパ部材に押されて上記作動部材が上記作動位置へ移動し、上記作動部材の動きを上記ロック係合部材に伝えて上記ロック係合部材を上記解除状態に切り換えるように構成する（請求項３）。
【００１０】
スライドドアが中間位置まで開く途中で作動位置にある状態のドア側ストッパ部材が作動部材に当接しこれを押すことで中間ロック部材とロック係合部材との係合が解除され、中間ロック部材のロック付勢部材の付勢力により中間ロック部材が作動位置へ移動させられるとともに、スライドドアが中間位置まで開く間、中間ロック部材が作動位置に保持される。スライドドアが中間位置へ到達するよりも前に中間ロック部材を作動位置へ移動させておくことができるためロック機構を中間ロック部材に確実に噛み合わせることができる。
【００１１】
上記作動手段は、上記作動部材の動きに連動して上記中間ロック部材が上記作動位置へ移動するように、上記作動部材と上記中間ロック部材を連結部材で連結する（請求項４）。
【００１２】
上記作動部材は、上記非作動位置ではスライドドア開閉に伴う上記ドア側ストッパ部材の移動軌跡上に位置し、上記作動位置ではスライドドアの開閉に伴う上記ドア側ストッパ部材の移動軌跡上から退いた位置に位置しており、スライドドアが上記中間位置よりも手前の所定の位置まで開いたとき上記ドア側ストッパ部材に押されて上記作動位置まで移動させられ、更にスライドドアが上記中間位置まで開く間、上記ドア側ストッパ部材に当接することにより上記非作動位置側へ移動するのを阻止されるように構成する（請求項５）。
【００１３】
スライドドアが中間位置まで開く途中で作動位置にある状態のドア側ストッパ部材が作動部材に当接しこれを押すことで連結部材を介して中間ロック部材が作動位置へ移動させられるとともに、スライドドアが中間位置まで開く間、中間ロック部材が作動位置に保持される。スライドドアが中間位置へ到達するよりも前に中間ロック部材を作動位置へ移動させておくことができるためロック機構を中間ロック部材に確実に噛み合わせることができる。
【００１４】
上記作動部材は、車体に回動自在に軸支された本体部に、スライドドアが上記中間位置よりも手前の所定の位置まで開いたときに上記ドア側ストッパ部材にスライドドアの開閉方向で当接し、更にスライドドアが上記中間位置まで開く間、上記ドア側ストッパ部材に押されて上記本体部と一体に回動しつつ上記本体部に対して伸長する当接部を設ける（請求項６）。車体へのドア建付けのばらつき等によりドア側ストッパ部材の移動軌跡が車体から離れても、確実に作動部材を作動位置へ回動させることができる。
【００１５】
上記作動手段は、上記作動部材が上記ドア側ストッパ部材に押されて移動したとき該作動部材が上記中間ロック部材を押して、該中間ロック部材を上記作動位置へ移動させるように構成する（請求項７）。
【００１６】
上記作動部材は、スライドドアが上記中間位置よりも手前の所定の位置まで開く間、上記ドア側ストッパ部材に押されて移動するように構成されており、
上記中間ロック部材は、上記非作動位置では上記作動部材の移動軌跡上に位置し、上記作動位置では上記作動部材の移動軌跡上から退いた位置に位置しており、スライドドアが上記中間位置よりも手前の所定の位置まで開いたとき上記作動部材に押されて上記作動位置へ移動させられ、更にスライドドアが上記中間位置まで開く間、上記作動部材に当接することにより上記非作動位置側へ移動するのを阻止されるように構成する（請求項８）。
【００１７】
スライドドアが中間位置まで開く途中で作動位置にある状態のドア側ストッパ部材が作動部材に当接しこれを押すことで中間ロック部材が作動位置へ移動させられるとともに、スライドドアが中間位置まで開く間、中間ロック部材が作動位置に保持される。スライドドアが中間位置へ到達するよりも前に中間ロック部材を作動位置へ移動させておくことができるためロック機構を中間ロック部材に確実に噛み合わせることができる。
【００１８】
上記移動手段は、スライドドアに設けられたドア窓の開度が規定量以上となったとき上記ドア側ストッパ部材を上記作動位置に移動させるように構成する（請求項９）。ドア窓の開閉動作に連動させてドア側ストッパ部材を作動させることができ、ドア窓の開度が規定量以上となったときドア側ストッパ部材を作動位置へ移動させることができる。
【００１９】
【発明の実施の形態】
図１ないし図３に基づいて本発明の第１の実施形態を説明する。図１に示すように、スライドドアＤには、ロアローラーＲを支持する支持ステーＲ１の前部にドア側ストッパ部材２が設置してある。ドア側ストッパ部材２は、基端が支軸２１により枢支され、先端を車体側へ突出せしめた作動位置（実線位置）と、ドア側に格納せしめた非作動位置（鎖線位置）とに回動可能に設けてある。ドア側ストッパ部材２は支軸２１まわりに設けられたバネ部材２２により矢印Ｅ方向へ付勢されている。ドア側ストッパ部材２は、スライドドア閉鎖時に車体側に設けられた図略の当接部材に押し回されて上記非作動位置へ格納され、ストッパ係合部材２０（移動手段）により非作動位置に保持される（尚、図１はスライドドアを中間位置へ開く途中を示す）。
【００２０】
ストッパ係合部材２０は支軸２３により回動自在に支持され、かつ付勢部材（図略）により矢印Ｆ方向へ付勢されている。ストッパ係合部材２０は、その一端に形成した係合爪２４を、ドア側ストッパ部材２の基端側外周に突設した係合部２５に係合せしめてドア側ストッパ部材２を上記非作動位置に保持する。またストッパ係合部材２０は、他端にワイヤ部材Ｗ１の一端が連結してあり、ワイヤ部材Ｗ１を介して、スライドドアＤの図略のウィンドレギュレータに付設され、窓ガラスを下降せしめてドア窓を所定の位置よりも開いた時（ドア窓の開度が規定量以上となったとき）に作動する作動装置と連動するようにしてある。ドア窓が所定の位置よりも開いた状態で上記作動装置が作動してワイヤ部材Ｗ１が矢印Ｇ方向へ引っ張られると、ストッパ係合部材２０は反矢印Ｆ方向へ回動して係合爪２４と係合部２５との係合が解除される。
【００２１】
これにより、ドア側ストッパ部材２は、上記バネ部材２２の付勢力により上記非作動位置から矢印Ｅ方向に車体側へ回動し、硬質ゴムのストッパ２６に当接してスライドドアＤに対してほぼ直角に車体側へ突出する上記作動位置に保持される。なお、ドア側ストッパ部材２の先端部の後縁にはゴムまたは合成樹脂からなるクッション材が設けてある。
【００２２】
支持ステーＲ１の後部には、ラッチ３とポール３０とからなるロック機構が設けてある。該ロック機構は後述の中間ロック部材５または全開ロック部材（図略）と係合してスライドドアＤを全開位置または全開位置よりも手前の中間位置に保持するものである。ラッチ３は、支軸３１により回動自在に軸支され、先端に設けられた係合溝３２をスライドドアＤに対して斜め後方かつ車体側へ向けて開口せしめたロック解除位置（実線位置）と、係合溝３２をスライドドアＤに対して直角方向に車体側へ向けて開口せしめたロック位置（鎖線位置）とに回動可能としてある。ラッチ３は、支軸３１まわりに設けたバネ部材３３により矢印Ｈ方向へ付勢され、通常、上記ロック解除位置に保持されている。
【００２３】
ポール３０は支軸３５により回動自在に支持され、かつ付勢部材（図略）により矢印Ｊ方向へ付勢されている。ポール３０は、その一端に形成した係合爪３６を、ラッチ３の外周に突設した係合部３４に係合せしめてラッチ３を上記ロック位置に保持する。またポール３０は、他端にワイヤ部材Ｗ２が連結してあり、該ワイヤ部材Ｗ２を介してスライドドアＤの図略のドアハンドルと連動するようにしてある。ドアハンドル（操作手段）を操作するとワイヤ部材Ｗ２が矢印Ｋ方向へ引っ張られ、ポール３０が反矢印Ｊ方向へ回動して係合爪３６と係合部３４との係合が解除される。これによりラッチ３は、上記バネ部材３３の付勢力により上記ロック位置から上記ロック解除位置へ復帰する。
【００２４】
車体には乗降口の開口下縁Ｂに沿ってスライドドアＤのロアローラーＲを案内するロアレールＳが設置してあり、乗降口の開口下縁Ｂの前後方向中間部にはスライドドアＤ側へ突出し、上記車体側へ突出した作動位置にある状態のドア側ストッパ部材２の先端部の移動軌跡上に車体側ストッパ部材１が設けてある。車体側ストッパ部材１は、ロアレールＳに固着され、スライドドアＤ側へ突出するブラケット１１の先端部前面に硬質のゴムブロックからなるクッション材１２を固着してあり、スライドドア開放時に作動位置のドア側ストッパ部材２と当接するように設置してある。
【００２５】
乗降口の開口下縁Ｂには車体側ストッパ部材１の後方位置に、上記スライドドアＤのラッチ３と係合可能な中間ロック部材５が設けてある。中間ロック部材５は、基端が支軸５１により回動自在に軸支された金属レバーで、先端にロックピン５２が立設してある。中間ロック部材５は、車体に対して先端を斜め前方かつドア側へ突出せしめた傾斜状の作動位置（鎖線位置）と、車体側に格納せしめた非作動位置（実線位置）とに回動可能に設置してある。中間ロック部材５は支軸５１まわりに設けられたバネ部材５３（ロック付勢部材）により矢印Ｌ方向へ付勢されている。中間ロック部材５は、スライドドア閉鎖時にスライドドアＤに設けられた硬質ゴムのブロック体からなる当接部材４により押圧（矢印Ｙ方向）されて上記非作動位置へ格納され、ロック係合部材５０により非作動状態に保持される。
【００２６】
ロック係合部材５０は支軸５５により回動自在に支持され、かつ付勢部材（図略）により矢印Ｍ方向へ付勢されている。ロック係合部材５０は、その一端に形成した係合爪５６を、上記非作動状態の中間ロック部材５の基端側外周に突設した係合部５７に係合せしめて中間ロック部材５を非作動状態に保持する。
【００２７】
車体の乗降口の開口下縁Ｂには、車体側ストッパ部材１の前方位置に、作動レバー６（作動部材）が設置してある。作動レバー６はほぼく字形に屈折しており、その屈折部が支軸６１により回動可能軸支されている。作動レバー６は、支軸６１まわりに設けられたバネ部材６２の付勢力により矢印Ｎ方向へ付勢されている。作動レバー６は、上記付勢力により矢印Ｎ方向へ回動して一方のレバー端６３をドア側へ突出せしめ、上記作動位置にあるドア側ストッパ部材２の先端部の移動軌跡上に位置する非作動位置（実線位置）から作動位置（鎖線位置）へ回動可能としてある。そして、作動レバー６の他方のレバー端はワイヤ部材Ｗ３により中間ロック部材５のロック係合部材５０の先端と連結してある。作動レバー６が上記作動位置へ回動すると、ワイヤ部材Ｗ３が矢印Ｑ方向へ引っ張られ、ロック係合部材５０を反矢印Ｍ方向へ回動させてロック係合部材５０の係合爪５６と中間ロック部材５の係合部５７との係合を解除するようにしてある。
【００２８】
次にこのように構成した車両用スライドドアの開位置保持装置の作動を図２および図３に基づいて説明する。スライドドアＤ閉鎖時、ドア側ストッパ部材２は上記非作動位置にあり、中間ロック部材５は上記非作動位置にある。図２に示すように、スライドドアＤの窓ガラスを下降してドア窓を所定の位置まで開くと、ストッパ係合部材２０と非作動位置のドア側ストッパ２との係合が解除され、ドア側ストッパ２が上記作動位置へ移動する。この状態でスライドドアＤを開方向（白矢印Ｘ）へ移動させると、ドア側ストッパ部材２の先端が車体側の作動レバー６のレバー端６３に当接するとともにこれを押して回動させ、作動レバー６が上記作動位置へ回動する。作動レバー６が上記作動位置へ回動すると、ワイヤ部材Ｗ３を介してロック係合部材５０が引っ張られ、ロック係合部材５０の係合爪５６と上記非作動位置の中間ロック部材５の係合部５７との係合が解除され、中間ロック部材５は上記作動位置へ回動する。
【００２９】
更に、スライドドアＤを開くと、図３に示すように、ドア側ストッパ部材２の先端が車体側ストッパ部材１に当接し、スライドドアＤの開方向（白矢印Ｘ方向）への移動を規制する。これとともに、両ストッパ部材１，２が当接する直前に、ドア側のロック機構のラッチ３の係合溝３２内に車体側の中間ロック部材５のロックピン５２が嵌入係合しつつ、ラッチ３が上記ロック位置へ回動する。そして、ドア側ストッパ部材２と車体側ストッパ部材１とが当接した時点で、ラッチ３がロック位置に至り、ラッチ３の係合部３４とポール３０の係合爪３６とが係合し、ラッチ３は中間ロック部材５と係合した状態でロックされる。この場合、スライドドアＤが中間位置へ到達するよりも前に中間ロック部材５を作動位置へ移動させておくことができるため、ラッチ３と中間ロック部材５を確実に係合ロックさせることができる。従って、スライドドアＤが閉方向（反白矢印Ｘ方向）へ移動しようとしても、ラッチ３の係合部３４とポール３０の係合爪３６との係合によりラッチ３が上記ロック解除位置へ回動せず、ラッチ３と中間ロック部材５との係合が解除されないので、スライドドアＤの閉方向への移動が規制され、スライドドアＤは中間位置に保持される。
【００３０】
中間位置からスライドドアＤを閉じるには、上記ドアハンドルを操作してラッチ３の係合部３４とポール３０の係合爪３６との係合を解除することでラッチ３のロックが解錠され、スライドドアＤを中間位置から閉じることができる。この場合、車体側の作動レバー６が上記非作動位置に復帰しており、閉方向へ移動するドア側ストッパ部材２の先端部が作動レバー６のレバー端６３に当接することとなるが、ドア側ストッパ部材２が上記非作動位置側へ回動して作動レバー６を回避する。そして、スライドドアＤが全閉位置に閉じると、ドア側ストッパ部材２は車体側の上記当接部材に押されて非作動位置側へ回動してストッパ係合部材２０により非作動位置に保持される。また全閉時のスライドドアＤの車体側への移動によりドア側の当接部材４（図１）が矢印Ｙ方向へ移動し、該当接部材４が中間ロック部材５を押して非作動位置側へ回動させ、中間ロック部材５はロック係合部材５０により非作動位置に保持される。
【００３１】
ドア窓を全閉または上記所定の位置よりも閉じた状態でスライドドアＤを開いた場合には、ドア側ストッパ部材２は作動せず上記非作動位置に保持され、車体側の中間ロック部材５も作動せず上記非作動位置に保持されているので、スライドドアＤを全開位置まで開くことができる。スライドドアＤが全開位置に至るとドア側のラッチ３が車体側の全開ロック部材と係合ロックしてスライドドアＤ全開位置に保持する。
【００３２】
本実施形態によれば、ドア窓を所定の位置以上に開いた状態でスライドドアＤを開いたとき、ドア側ストッパ部材２と車体側ストッパ部材１との当接により、スライドドアＤの中間位置から全開位置側への移動が規制され、かつドア側のラッチ３による中間ロック部材５との係合ロックにより、スライドドアＤの中間位置から閉方向への移動が規制される。従って、スライドドアＤを中間位置に確実に保持することができ、下り坂等に駐車した状態でスライドドアＤを中間位置まで開いても不意に閉まることがない。また、スライドドアＤを中間位置で止めるためのドア側ストッパ部材５とは別に、スライドドアＤを中間位置で保持するためのロック機構３が設けられているため、ロック機構３にスライドドアを中間位置で止めるための衝撃が作用せず破損を防ぐことできる。作動レバー６は、ドア側ストッパ部材１を利用して中間ロック部材５を移動させるようにしたので構成部品が少なくすむ。
【００３３】
次に、図４および図５に基づいて本発明の第２の実施形態を説明する。尚、図において、第１の実施形態と同一部材は同一符号で表し、それらの説明は省略する。図４に示すように、車体の乗降口の開口下縁Ｂには車体側ストッパ部材１が取付けであり、車体側ストッパ部材１の後方位置には中間ロック部材５Ａが設けてある。中間ロック部材５Ａは、ほぼＬ字形をなす金属レバーで、屈曲部が支軸５１により回動自在に軸支され、ロックピン５２を立設した一端が車体に対して斜め前方かつドア側へ突出せしめた傾斜状の作動位置（鎖線位置）と、車体側に格納せしめた非作動位置（実線位置）とに回動可能としてある。中間ロック部材５Ａは支軸５１まわりに設けられたバネ部材５３ａ（ロック付勢部材）により矢印Ｔ方向へ付勢されている。
【００３４】
車体側ストッパ部材１の直前位置には、中間ロック部材５Ａを上記作動位置および上記非作動位置へ回動する作動レバー６Ａが設置してある。作動レバー６Ａは緩やかに屈曲するほぼく字形をなし、屈曲部が支軸６１により回動可能に軸支されている。作動レバー６Ａは、その一方のレバー端６３を斜め後方かつドア側へ突出せしめ、上記車体側へ突出したドア側ストッパ部材２の先端と対向する非作動位置（実線位置）と、レバー端６３が車体側へ引っ込んだ作動位置（鎖線位置）へ回動可能としてある。
【００３５】
作動レバー６Ａは、上記非作動位置にある状態で中間ロック部材５Ａが上記非作動位置となるように、作動レバー６Ａの他方のレバー端と中間ロック部材５Ａの他端とを連結ロッド６４（連結部材）により連結してあり、作動レバー６が上記作動位置へ回動すると中間ロック部材５Ａが上記作動位置へ回動するようにしてある。通常、中間ロック部材５Ａのバネ部材５３ａの付勢力により中間ロック部材５Ａは非作動位置となり、作動レバー６Ａは非作動位置となっている。
【００３６】
このように構成したスライドドアの開位置保持装置は、ドア窓が所定の位置まで開いた状態でスライドドアＤを開方向（白矢印Ｘ方向）へ移動すると、車体側へ突出したドア側ストッパ部材２の先端部が車体側の作動レバー６Ａの一方のレバー端６３に当接するとともにこれを押して、作動レバー６Ａを上記作動位置へ回動させる。作動レバー６Ａが上記作動位置へ回動すると、連結ロッド６４を介して中間ロック部材５Ａの他端が引っ張られ、中間ロック部材５Ａはバネ部材５３ａの付勢力に抗して上記作動位置へ回動する。
【００３７】
そして図５に示すように、ドア側ストッパ部材２の先端が車体側ストッパ部材１に当接し、スライドドアＤの開方向（白矢印Ｘ）への移動を規制する。このとき作動レバー６ａは車体側ストッパ部材１に当接したドア側ストッパ部材２により作動位置に保持され、中間ロック部材５Ａも作動位置に保持される。そして中間ロック部材５Ａのロックピン５２がドア側のロック機構のラッチ３の係合溝３２内に嵌入係合し、ラッチ３が上記ロック位置へ回動し、ラッチ３がロック位置に至るとラッチ３の係合部３４とポール３０の係合爪３６とが係合し、ラッチ３は中間ロック部材５と係合した状態でロックされる。スライドドアＤが中間位置へ到達するよりも前に中間ロック部材５Ａを作動位置へ移動させておくことができるため、ラッチ３と中間ロック部材５Ａを確実に係合ロックさせることができる。これによりスライドドアＤは中間位置に保持される。
【００３８】
中間位置からスライドドアＤを閉じるには、上記ドアハンドルを操作してラッチ３の係合部３４とポール３０の係合爪３６との係合を解除しラッチ３のロックを解除することで閉じる。スライドドアＤを閉じ、ドア側ストッパ部材２が作動レバー６Ａから離れると、中間ロック部材５Ａがバネ部材５３ａの付勢力により上記非作動位置へ回動し、これにより作動レバー６Ａも上記非作動位置に復帰する。スライドドアＤが全閉位置に至ると、ドア側ストッパ部材２も車体側の上記当接部材により上記非作動位置へ格納される。
【００３９】
ドア窓を全閉または上記所定の位置よりも閉じた状態でスライドドアＤを開いた場合には、ドア側ストッパ部材２が作動せず、車体側の中間ロック部材５Ａも作動しないので、スライドドアＤを全開位置まで開くことができる。スライドドアＤが全開位置に至るとドア側のラッチ３が車体側の全開ロック部材を係合ロックしてスライドドアＤを全開位置に保持する。
【００４０】
本実施形態によれば、第１の実施形態と同様な作用効果が得られ、スライドドアＤを中間位置に確実に保持することができる。また、中間ロック部材５Ａを上記作動位置および上記非作動位置へ回動せしめる作動手段の構造の簡素化がはかれる。
【００４１】
図６および図７は第２の実施形態に用いる他の作動部材を示す。他の作動部材たる作動レバー６Ｂはドア側ストッパ部材２と当接する伸縮自在な当接部６５を備えている。作動レバー６Ｂには、ほぼく字形をなす本体部６０に、その屈曲部付近から一方のレバー端６３に向けてスライド溝６６が形成してある。該スライド溝６６には、先端を一方のレバー端６３より突出せしめた当接部６５がスライド移動可能に嵌入してあり、当接部６０は上記レバー端６３を延長するように伸長し、かつ収縮可能に設けてある。当接部６０はスライド溝６６内に設けたバネ部材６７の付勢力により収縮方向（矢印Ｕ方向）に付勢されている。当接部６５の先端はレバー端６３に対して直角かつドア側へ屈折してある。
【００４２】
作動レバー６Ｂは、その本体部６０の中間が支軸６１により回転自在に軸支され、非作動位置（図６）と作動位置（図７）とに回動可能としてある。作動レバー６Ｂは、上記非作動位置で他方のレバー端の一方の側縁が第１のストッパピン６８に当接し、上記作動位置では他方のレバー端の他方の側縁が第２のストッパピン６９に当接する。作動レバー６Ｂは、連結ロッド６４を介して他方のレバー端と中間ロック部材５Ａ（図４、図５）とが連結され、通常、中間ロック部材５Ａの上記非作動位置への回動に連動して上記非作動位置に保持されている。
【００４３】
作動レバー６Ｂは、スライドドアの開方向（白矢印Ｘ方向）への移動時に、上記作動位置にある状態のドア側ストッパ部材２の先端部が、当接部６５の先端部に当接しこれを押すことにより、当接部６５が作動レバー６Ｂの本体部と一体に上記作動位置側へ回動しつつ、本体部６０に対して当接部６５が伸長する。そして、ドア側ストッパ部材２が当接部６５の先端部を介して車体側ストッパ部材１に当接し、作動レバー６Ｂはその他方のレバー端の側縁が第２のストッパピン６９に当接して、完全に上記作動位置へ回動する。以下、第２の実施形態と同様な作用によりスライドドアが中間位置に保持される。
【００４４】
このように作動レバー６Ｂを用いることで、例えば、車体へのスライドドアの建付けのばらつきにより、車体側へ突出したドア側ストッパ部材２の移動軌跡が車体から離れている場合、図４および図５に示した作動レバー６Ａでは、ドア側ストッパ部材２に押されて回動する作動レバー６Ａの回動角度が小さくなるため、作動レバー６Ａの小さな回動でも確実に中間ロック部材５Ａが上記作動位置に回動するように、連結ロッド６４等の長さを調整しなければならないが、作動レバー６Ｂは、伸縮自在な当接部６５の伸長により一方のレバー端６３を延長するようにしたので、上記建付けのばらつきがあっても確実に作動レバー６Ｂを上記作動位置へ回動させることができ、連結ロッド６４等の調整が不要である。
【００４５】
次に、図８ないし図１０に基づいて本発明の第３の実施形態を説明する。尚、図において、第１の実施形態と同一部材は同一符号で表し、それらの説明は省略する。図８に示すように、車体の乗降口の開口下縁ＢにはロアレールＳに沿ってベースプレートＢ１が取付けてあり、ベースプレートＢ１にはスライドドアＤの開閉方向である車両前後方向に沿ってスライドレール７０が設置してある。スライドレール７０にはこれに沿ってスライド移動自在なスライドレバー７（作動部材）が設けてある。スライドレバー７は、前端および後端に設けた前後一対のスライド部７１ａ，７１ｂをスライドレール７０に摺動可能に嵌入してある。スライドレバー７は、スライドレール７０の前端とスライド部７１ａとの間に架けわたしたバネ部材７２の付勢力により前方（矢印Ｖ方向）へ付勢され、通常、前方に位置している。スライドレバー７の前端には、スライドドアＤ側へ突出し、かつ作動位置にある状態のドア側ストッパ部材２の先端部の移動軌跡上に位置する当接部７３が突設してある。当接部７３の前面にはゴム製のクッション材が設けてある。
【００４６】
ベースプレートＢ１には、後部にスライドドアＤ側へ突出し、作動位置のドア側ストッパ部材２の先端部およびスライドレバー７の当接部７３の移動軌跡上に位置する車体側ストッパ部材１Ａが取付けてある。車体側ストッパ部材１ＡはベースプレートＢ１に固着したブラケット１１ａの前端縁にゴムのブロック体からなるクッション材１２が設置してある。
【００４７】
車体側ストッパ部材１Ａのブラケット１１ａには、クッション材１２の後方位置に、スライドドアＤのラッチ３と係合可能な中間ロック部材５Ｂが設けてある。中間ロック部材５Ｂは、基端が支軸５１により回動自在に軸支された金属レバーで、先端にロックピン５２が立設してある。中間ロック部材５Ｂは、車体に対して先端を斜め後方かつドア側へ突出せしめた傾斜状の作動位置（鎖線位置）と、車体側に格納せしめた非作動位置（実線位置）とに回動可能に設置してある。中間ロック部材５Ｂは支軸５１まわりに設けられたバネ部材５３ｂ（ロック付勢部材）により矢印Ｚ方向へ付勢され、通常、上記非作動位置にある。中間ロック部材５Ｂには基端側にスライドレール７０側へ膨出する膨出部が形成してあり、該膨出部には上記非作動位置でスライドレバー７の移動軌跡上に突出する当接ローラー５８が取付けてある。
【００４８】
このように構成した第３の実施形態の位置保持装置は、ドア窓が所定の位置まで開いた状態でスライドドアＤを開方向（白矢印Ｘ）へ移動すると、図９に示すように、作動位置にあるドア側ストッパ部材２の先端部が車体側のスライドレバー７の当接部７３に当接してこれを後方へ押し動かす。スライドレバー７が後方へスライド移動すると、スライドレバー７の後端７４が中間ロック部材５Ｂの当接ローラー５８に当接し、これをスライドレバー７の移動軌跡から押し出す。このとき当接ローラー５８がスライドレバー７の後端７４の端面からドア側のレバー側面へ転動移動し、中間ロック部材５Ｂは上記作動位置へ回動する。
【００４９】
そして図１０に示すように、ドア側ストッパ部材２の先端部とこれにより押し動かされて後方へ移動したスライドレバー７の当接部７３が一体に車体側ストッパ部材１Ａに当接し、スライドドアＤの開方向（白矢印Ｘ）への移動を規制する。このとき、後方に位置するスライドレバー７により中間ロック部材５Ｂは作動位置に保持される。そして中間ロック部材５Ｂのロックピン５２がドア側のロック機構のラッチ３の係合溝３２内に嵌入係合し、ラッチ３が上記ロック位置へ回動し、ラッチ３がロック位置に至るとラッチ３の係合部３４とポール３０の係合爪３６とが係合し、ラッチ３は中間ロック部材５Ｂと係合した状態でロックされる。スライドドアＤが中間位置へ到達するよりも前に中間ロック部材５Ｂを作動位置へ移動させ、ラッチ３と中間ロック部材５Ｂを確実に係合ロックさせることができる。これによりスライドドアＤは中間位置に保持される。
【００５０】
中間位置からスライドドアＤを閉じるには、第１および第２の実施形態と同様に上記ドアハンドルを操作してラッチ３のロックを解除することで閉じる。スライドドアＤを閉方向（前方）へ移動すると、ドア側ストッパ部材２の前方への移動に伴いスライドレバー７も前方へ移動し、スライドレバー７の後端７４が中間ロック部材５Ｂの当接ローラー５８から離れると、中間ロック部材５Ｂはバネ部材５３ｂの付勢力により上記非作動位置へ回動する。
【００５１】
ドア窓を全閉または上記所定の位置よりも閉じた状態でスライドドアＤを開いた場合には、ドア側ストッパ部材２が作動せず、車体側の中間ロック部材５Ｂも作動しないので、スライドドアＤを全開位置までスムーズに開くことができ、ラッチ３が車体側の全開ロック部材を係合ロックしてスライドドアＤを全開位置に保持する。
【００５２】
本実施形態によれば、第１および第２の実施形態と同様な作用効果が得られ、スライドドアＤを中間位置に確実に保持することができ、下り坂等に駐車した状態でスライドドアＤを中間位置まで開いても不意に閉まることがない。また、中間ロック部材５Ｂを上記作動位置および上記非作動位置へ回動せしめる作動手段としてスライドレバー７を用いる構造としたで、車体へのスライドドアの建付けのばらつきが生じて車体側へ突出したドア側ストッパ部材２の移動軌跡が車体から離れても確実に中間ロック部材５Ｂを作動位置に回動せしめることができる。
【００５３】
【発明の効果】
本発明のスライドドアの開位置保持装置によれば、スライドドアの中間位置から開方向への移動を確実に規制するとともに、中間位置から閉方向への移動も確実に規制することができ、スライドドアの中間位置からの不意の閉じ移動を防ぐことができる。

The present invention provides a vehicle-body-side stopper member provided on a vehicle body, and is provided on a slide door, and is movable between an operating position and a non-operating position. When the door is opened to the intermediate position, the door abuts on the vehicle body side stopper member to restrict the slide door from opening beyond the intermediate position, and in the state where the slide door is in the inoperative position, the slide door is allowed to open to the fully open position. Side stopper member, moving means for moving the door-side stopper member, a lock mechanism provided on the slide door, provided on the vehicle body, movable to an operating position and a non-operating position, and in the operating position Then, when the sliding door is opened to the intermediate position, the sliding door is engaged with the lock mechanism to hold the sliding door at the intermediate position. An intermediate lock member that allows the door to open to the fully open position, operating means for releasing the engagement of the lock mechanism with the intermediate lock member, and a state in which the door-side stopper member is in the operating position, the slide door is Actuating means for moving the intermediate lock member to the operating position during opening from the fully closed position to the intermediate position (claim 1). When the door-side stopper member is in the operating position and the slide door is opened in this state, the intermediate lock member on the vehicle body is moved to the operating position by the operating means. When the slide door reaches the intermediate position, the door-side stopper member comes into contact with the vehicle body-side stopper member, and the intermediate lock member, which has been in the operating position, engages with the door lock mechanism, and the slide door opens beyond the intermediate position. While regulating, the slide door is held at the intermediate position. Therefore, the door does not close unexpectedly even on a downhill. The engagement of the lock mechanism with the intermediate lock member can be released by the operating means and the door can be closed. When the slide door is opened in a state where the door-side stopper member is at the non-operation position, the intermediate lock member does not operate, and the slide door can be opened to the full open position. A lock mechanism for holding the slide door at the intermediate position is provided separately from the door side stopper member for stopping the slide door at the intermediate position. It can be prevented from being transmitted and damaged.

When the slide door D is closed, the door-side stopper member 2 is in the inoperative position, and the intermediate lock member 5 is in the inoperative position. As shown in FIG. 2, when the window glass of the sliding door D is lowered and the door window is opened to a predetermined position, the engagement between the stopper engaging member 20 and the door-side stopper 2 in the inoperative position is released, and the door is disengaged. The side stopper 2 moves to the operating position. When the slide door D is moved in the opening direction (white arrow X) in this state, the tip of the door-side stopper member 2 comes into contact with the lever end 63 of the operation lever 6 on the vehicle body side and pushes it to rotate. 6 pivots to the operating position. When the operating lever 6 is rotated to the operating position, the lock engaging member 50 is pulled via the wire member W3, and the engaging claw 56 of the lock engaging member 50 is engaged with the intermediate lock member 5 at the non-operating position. The engagement with the portion 57 is released, and the intermediate lock member 5 rotates to the operation position.
[0029]
Further, when the sliding door D is opened, as shown in FIG. 3, the tip of the door-side stopper member 2 abuts on the vehicle-body-side stopper member 1 to restrict the movement of the sliding door D in the opening direction (the direction of the white arrow X). I do. At the same time, immediately before the stopper members 1 and 2 come into contact with each other, the lock pin 52 of the vehicle body-side intermediate lock member 5 is fitted into the engagement groove 32 of the latch 3 of the door-side lock mechanism. Rotates to the lock position. Then, when the door-side stopper member 2 and the vehicle-body-side stopper member 1 come into contact with each other, the latch 3 reaches the lock position, and the engaging portion 34 of the latch 3 and the engaging claw 36 of the pawl 30 are engaged. The latch 3 is locked while being engaged with the intermediate lock member 5. In this case, since the intermediate lock member 5 can be moved to the operating position before the slide door D reaches the intermediate position, the latch 3 and the intermediate lock member 5 can be reliably engaged and locked. . Therefore, even if the slide door D moves in the closing direction (the direction of the anti-white arrow X), the latch 3 is rotated to the unlock position by the engagement between the engaging portion 34 of the latch 3 and the engaging claw 36 of the pawl 30. Since it does not move and the engagement between the latch 3 and the intermediate lock member 5 is not released, the movement of the slide door D in the closing direction is restricted, and the slide door D is held at the intermediate position.
[0030]
To close the slide door D from the intermediate position, the lock of the latch 3 is unlocked by operating the door handle to release the engagement between the engagement portion 34 of the latch 3 and the engagement claw 36 of the pawl 30. The sliding door D can be closed from the intermediate position. In this case, the operating lever 6 on the vehicle body side has returned to the non-operating position, and the distal end of the door-side stopper member 2 moving in the closing direction comes into contact with the lever end 63 of the operating lever 6. The side stopper member 2 rotates toward the non-operation position to avoid the operation lever 6. When the slide door D is closed to the fully closed position, the door-side stopper member 2 is pushed by the contact member on the vehicle body side and pivots toward the non-operation position, and is held at the non-operation position by the stopper engagement member 20. Is done. Further, when the slide door D is moved toward the vehicle body when fully closed, the contact member 4 (FIG. 1) on the door side moves in the direction of the arrow Y, and the contact member 4 pushes the intermediate lock member 5 to the inoperative position. When rotated, the intermediate lock member 5 is held at the non-operation position by the lock engagement member 50.
[0031]
When the slide door D is opened with the door window fully closed or closed from the predetermined position, the door-side stopper member 2 does not operate and is held at the non-operation position, and the vehicle-side intermediate locking member 5 Is not actuated and is held at the inoperative position, so that the slide door D can be opened to the fully open position. When the slide door D reaches the fully open position, the latch 3 on the door side is engaged and locked with the fully open lock member on the vehicle body side to hold the slide door D at the fully open position.
[0032]
According to the present embodiment, when the slide door D is opened in a state where the door window is opened to a predetermined position or more, the contact between the door-side stopper member 2 and the vehicle-body-side stopper member 1 causes the intermediate position of the slide door D. From the intermediate position to the fully open position side, and the engagement of the door side latch 3 with the intermediate lock member 5 restricts the movement of the slide door D from the intermediate position to the closing direction. Therefore, the sliding door D can be reliably held at the intermediate position, and the sliding door D does not close unexpectedly even if the sliding door D is opened to the intermediate position while parked on a downhill or the like. Further, a lock mechanism 3 for holding the slide door D at the intermediate position is provided separately from the door-side stopper member 5 for stopping the slide door D at the intermediate position. The impact for stopping at the position does not act, and damage can be prevented. The operating lever 6 uses the door-side stopper member 1 to move the intermediate lock member 5, so that the number of components is reduced.
[0033]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the drawings, the same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG. 4, a vehicle-body-side stopper member 1 is attached to the lower edge B of the entrance of the vehicle, and an intermediate lock member 5A is provided at a position behind the vehicle-side stopper member 1. The intermediate locking member 5A is a metal lever having a substantially L-shape. The bent portion is rotatably supported by the support shaft 51, and one end where the lock pin 52 is erected projects obliquely forward and toward the door with respect to the vehicle body. It is rotatable between an inclined operating position (dashed line position) and a non-operating position (solid line position) stored on the vehicle body side. The intermediate lock member 5A is urged in the direction of arrow T by a spring member 53a (lock urging member) provided around the support shaft 51.
[0034]
An operation lever 6A for rotating the intermediate lock member 5A to the above-mentioned operation position and the above-mentioned non-operation position is provided immediately before the vehicle-body-side stopper member 1. The operation lever 6A has a substantially rectangular shape that is gently bent, and the bent portion is rotatably supported by a support shaft 61. The operating lever 6A has one lever end 63 projecting obliquely rearward and toward the door, and a non-operating position (solid line position) opposing the distal end of the door-side stopper member 2 projecting toward the vehicle body, and the lever end 63. It is rotatable to an operating position (chain line position) retracted toward the vehicle body.
[0035]
The operating lever 6A connects the other end of the operating lever 6A and the other end of the intermediate locking member 5A to the connecting rod 64 (connecting) so that the intermediate locking member 5A is at the non-operating position in the non-operating position. The intermediate lock member 5A is rotated to the operating position when the operating lever 6 is rotated to the operating position. Normally, the intermediate lock member 5A is in the non-operation position and the operating lever 6A is in the non-operation position by the urging force of the spring member 53a of the intermediate lock member 5A.
[0036]
When the slide door D is moved in the opening direction (the direction of the white arrow X) with the door window opened to a predetermined position, the door-side stopper member protruding toward the vehicle body is configured as described above. The front end of the lever 2 contacts one lever end 63 of the operation lever 6A on the vehicle body side and pushes the lever end 63 to rotate the operation lever 6A to the operation position. When the operating lever 6A rotates to the operating position, the other end of the intermediate locking member 5A is pulled via the connecting rod 64, and the intermediate locking member 5A rotates to the operating position against the urging force of the spring member 53a. I do.
[0037]
Then, as shown in FIG. 5, the distal end of the door-side stopper member 2 abuts on the vehicle-body-side stopper member 1 to regulate the movement of the slide door D in the opening direction (white arrow X). At this time, the operating lever 6a is held at the operating position by the door-side stopper member 2 abutting on the vehicle-body-side stopper member 1, and the intermediate lock member 5A is also held at the operating position. Then, the lock pin 52 of the intermediate lock member 5A fits into the engagement groove 32 of the latch 3 of the door-side lock mechanism, and the latch 3 rotates to the above-described lock position. 3 and the pawl 30 and the engaging claw 36 of the pawl 30 are engaged, and the latch 3 is locked in a state of being engaged with the intermediate lock member 5. Since the intermediate lock member 5A can be moved to the operating position before the slide door D reaches the intermediate position, the latch 3 and the intermediate lock member 5A can be reliably engaged and locked. As a result, the slide door D is held at the intermediate position.
[0038]
To close the slide door D from the intermediate position, the door handle is operated to release the engagement between the engaging portion 34 of the latch 3 and the engaging claw 36 of the pawl 30 and release the lock of the latch 3 to close. . When the slide door D is closed and the door-side stopper member 2 is separated from the operation lever 6A, the intermediate lock member 5A is rotated to the non-operation position by the urging force of the spring member 53a, whereby the operation lever 6A also moves to the non-operation position. Return to. When the slide door D reaches the fully closed position, the door-side stopper member 2 is also stored in the inoperative position by the contact member on the vehicle body side.
[0039]
When the slide door D is opened in a state where the door window is fully closed or closed from the predetermined position, the door-side stopper member 2 does not operate, and the vehicle-body-side intermediate lock member 5A does not operate. D can be opened to the fully open position. When the slide door D reaches the fully open position, the latch 3 on the door side engages and locks the fully open lock member on the vehicle body side to hold the slide door D at the fully open position.
[0040]
According to this embodiment, the same operation and effect as those of the first embodiment can be obtained, and the slide door D can be reliably held at the intermediate position. In addition, the structure of the actuating means for rotating the intermediate lock member 5A to the operating position and the non-operating position is simplified.
[0041]
6 and 7 show another operating member used in the second embodiment. The operation lever 6B, which is another operation member, includes an extendable contact portion 65 that contacts the door-side stopper member 2. In the operating lever 6B, a slide groove 66 is formed in a substantially rectangular main body portion 60 from the vicinity of the bent portion toward one lever end 63. A contact portion 65 having a tip protruding from one lever end 63 is slidably fitted into the slide groove 66, and the contact portion 60 extends so as to extend the lever end 63, and It is provided so as to be contractible. The contact portion 60 is urged in the contracting direction (the direction of the arrow U) by the urging force of a spring member 67 provided in the slide groove 66. The tip of the contact portion 65 is bent at right angles to the lever end 63 and toward the door.
[0042]
The operation lever 6B is rotatably supported at the center of the main body 60 by a support shaft 61, and is rotatable between a non-operation position (FIG. 6) and an operation position (FIG. 7). The operating lever 6B has one side edge of the other lever end in contact with the first stopper pin 68 in the non-operating position, and has the other side edge of the other lever end in the second stopper pin 69 in the operating position. Abut. The operating lever 6B has the other lever end connected to the intermediate lock member 5A (FIGS. 4 and 5) via the connecting rod 64, and is normally interlocked with the rotation of the intermediate lock member 5A to the non-operating position. In the inoperative position.
[0043]
When the operating lever 6B moves in the opening direction of the slide door (the direction of the white arrow X), the distal end of the door-side stopper member 2 in the operating position contacts the distal end of the abutting portion 65. By pressing, the contact portion 65 is extended with respect to the main body 60 while the contact portion 65 is rotated toward the operation position side integrally with the main body of the operation lever 6B. Then, the door-side stopper member 2 comes into contact with the vehicle-body-side stopper member 1 via the front end of the contact portion 65, and the operating lever 6B comes into contact with the second stopper pin 69 at the side edge of the other lever end. , Completely pivoting to the operating position. Hereinafter, the slide door is held at the intermediate position by the same operation as in the second embodiment.
[0044]
By using the operating lever 6B in this manner, for example, when the movement trajectory of the door-side stopper member 2 protruding toward the vehicle body is separated from the vehicle body due to variation in the construction of the slide door on the vehicle body, FIGS. In the operation lever 6A shown in FIG. 5, the rotation angle of the operation lever 6A which is rotated by being pushed by the door-side stopper member 2 becomes small, so that even when the operation lever 6A is smallly rotated, the intermediate lock member 5A can be operated reliably. Although the length of the connecting rod 64 and the like must be adjusted so as to rotate to the position, the operating lever 6B is configured to extend one lever end 63 by extending the extendable abutting portion 65. Therefore, even if there is a variation in the installation, the operating lever 6B can be surely rotated to the operating position, and adjustment of the connecting rod 64 and the like is unnecessary.
[0045]
Next, a third embodiment of the present invention will be described with reference to FIGS. In the drawings, the same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG. 8, a base plate B1 is attached to a lower edge B of an entrance of a vehicle body along a lower rail S, and a slide rail is attached to the base plate B1 in a vehicle front-rear direction which is an opening / closing direction of a slide door D. 70 is installed. The slide rail 70 is provided with a slide lever 7 (operating member) slidable along the slide rail 70. The slide lever 7 has a pair of front and rear slide portions 71a and 71b provided at a front end and a rear end slidably fitted on a slide rail 70. The slide lever 7 is urged forward (in the direction of the arrow V) by the urging force of a spring member 72 spanned between the front end of the slide rail 70 and the slide portion 71a, and is normally located forward. At the front end of the slide lever 7, an abutment portion 73 protruding toward the slide door D and located on the movement locus of the distal end of the door-side stopper member 2 in the operating position is protruded. A rubber cushion material is provided on the front surface of the contact portion 73.
[0046]
A vehicle-body-side stopper member 1A, which protrudes toward the slide door D side at the rear and is located on the movement trajectory of the distal end portion of the door-side stopper member 2 in the operating position and the contact portion 73 of the slide lever 7, is attached to the base plate B1. . In the vehicle body side stopper member 1A, a cushion member 12 made of a rubber block body is installed on a front end edge of a bracket 11a fixed to a base plate B1.
[0047]
The bracket 11a of the vehicle body side stopper member 1A is provided at the rear position of the cushion member 12 with an intermediate lock member 5B that can be engaged with the latch 3 of the slide door D. The intermediate lock member 5B is a metal lever whose base end is rotatably supported by a support shaft 51, and a lock pin 52 is provided upright at the distal end. The intermediate lock member 5B is rotatable between an inclined operating position (dashed line position) in which the tip protrudes obliquely rearward and the door side with respect to the vehicle body, and a non-operating position (solid line position) stored in the vehicle body side. It is installed in. The intermediate lock member 5B is urged in the direction of the arrow Z by a spring member 53b (lock urging member) provided around the support shaft 51, and is normally at the non-operation position. The intermediate lock member 5B has a bulging portion bulging toward the slide rail 70 on the base end side, and the bulging portion abuts on the movement trajectory of the slide lever 7 at the inoperative position. A roller 58 is mounted.
[0048]
When the slide door D is moved in the opening direction (white arrow X) with the door window opened to the predetermined position, the position holding device of the third embodiment configured as described above operates as shown in FIG. The distal end portion of the door-side stopper member 2 at the position contacts the contact portion 73 of the slide lever 7 on the vehicle body side and pushes it backward. When the slide lever 7 slides rearward, the rear end 74 of the slide lever 7 comes into contact with the contact roller 58 of the intermediate lock member 5B, and pushes this out of the movement locus of the slide lever 7. At this time, the contact roller 58 rolls from the end face of the rear end 74 of the slide lever 7 to the side of the lever on the door side, and the intermediate lock member 5B rotates to the operating position.
[0049]
Then, as shown in FIG. 10, the distal end portion of the door-side stopper member 2 and the contact portion 73 of the slide lever 7 which has been pushed and moved rearward by this integrally contact the vehicle body-side stopper member 1A, and the slide door D In the opening direction (white arrow X). At this time, the intermediate lock member 5B is held at the operating position by the slide lever 7 located rearward. Then, the lock pin 52 of the intermediate lock member 5B fits into the engagement groove 32 of the latch 3 of the lock mechanism on the door side, the latch 3 rotates to the lock position, and when the latch 3 reaches the lock position, the latch The latch 3 is locked in a state of being engaged with the intermediate lock member 5B by the engagement of the engagement portion 34 of the pole 3 and the engagement claw 36 of the pawl 30. The intermediate lock member 5B can be moved to the operating position before the slide door D reaches the intermediate position, and the latch 3 and the intermediate lock member 5B can be reliably engaged and locked. As a result, the slide door D is held at the intermediate position.
[0050]
In order to close the slide door D from the intermediate position, the door 3 is closed by operating the door handle and unlocking the latch 3 as in the first and second embodiments. When the slide door D moves in the closing direction (forward), the slide lever 7 also moves forward with the forward movement of the door-side stopper member 2, and the rear end 74 of the slide lever 7 is brought into contact with the contact roller of the intermediate lock member 5B. When the intermediate lock member 5B moves away from the position 58, the intermediate lock member 5B rotates to the inoperative position by the urging force of the spring member 53b.
[0051]
When the slide door D is opened in a state where the door window is fully closed or closed from the predetermined position, the door side stopper member 2 does not operate and the vehicle body side intermediate lock member 5B does not operate. D can be smoothly opened to the fully open position, and the latch 3 engages and locks the fully open lock member on the vehicle body side to hold the slide door D at the fully open position.
