Description

【０００１】
【発明の属する技術分野】
本発明は、引戸の袖壁構造に関し、詳しくは引戸を開く際の指詰め防止を図ることができる技術に関するものである。
【０００２】
【従来の技術】
一般の直線的に移動する引戸は、閉じた際に戸先に隙間が生じやすく、遮音性、密閉性に劣るという問題がある。
【０００３】
そこで、従来、全開状態では引戸が袖壁と略平行に対面する位置で保持され、閉じる直前には引戸が傾斜レールに誘導されて出入口方向に移動して、引戸の戸先が戸先側の縦枠に当たり且つ引戸の戸尻が袖壁の先端に設けた戸当たり部に当たることで全閉状態での密閉度を高めるようにした構造が知られている（例えば、特許文献１参照）。

【発明が解決しようとする課題】
ところで、直線的に移動するタイプの引戸にあっては、引戸を開く際に引戸の戸尻と袖壁との間で手指を挟むことがないが、これに対して図１２に示すように、閉じる直前に出入口方向Ａに移動するタイプの引戸１にあっては、閉じる際に引戸１の戸尻１ｂが袖壁２の先端角部１５に接触することなく戸当たり部５に当接可能とするために、戸当たり部５を袖壁２の先端角部１５よりも出入口方向Ａに入り込んだ位置に段差状に設けている。このため、戸当たり部５から袖壁２の先端角部１５に至る段差部６によって引戸１が全閉状態にあるときは引戸１の戸尻１ｂと袖壁２の先端との間に広い隙間９が生じ、この隙間９に手指を置いた場合は、図１２の矢印方向ａに引戸１を開く際に引戸１の戸尻１ｂによって手指が挟まれる恐れがあった。なお図１２中の５０は化粧額縁である。
【０００６】
本発明は、上記の従来例の問題点に鑑みて発明したものであって、その目的とするところは、引戸を開く際に引戸の戸尻によって手指が挟まれる恐れをなくして安全に引戸の開閉操作を行なえるようにすると共に、引戸の全閉状態での見栄えを良くすることができる引戸の袖壁構造を提供することにあり、他の目的とするところは、引戸の戸尻の出入口方向の密閉度を簡単且つ確実に高めることができる引戸の袖壁構造を提供することにあり、他の目的とするところは、傾斜部材の取付操作を容易にしながら外観性を向上させることができる引戸の袖壁構造を提供することにあり、さらに他の目的とするところは、従来のけんどん式を用いずに、引戸の上端部の隙間を小さくして見栄えを一層良くすると共に開閉操作性を一層向上させることができる引戸の袖壁構造を提供することにある。
【０００７】
【課題を解決するための手段】
上記課題を解決するために本発明にあっては、引戸１が全閉状態では袖壁２と略平行に対面する位置で保持され、閉じる直前には傾斜レール３Ａに誘導されて出入口方向Ａに移動して、引戸１の戸尻１ｂが袖壁２の先端に設けた戸当たり部５に当たることで全閉状態での密閉度を高めるようにした引戸の袖壁構造において、引戸１の戸尻１ｂが当たる戸当たり部５を袖壁２の先端角部１５よりも出入口方向Ａに入り込んだ位置に段差状に設けると共に、戸当たり部５から袖壁２の先端角部１５に至る段差部６内に上記傾斜レール３Ａと略平行に傾斜した指詰め防止用の傾斜部材７を設け、全閉状態にある引戸１の戸尻１ｂと傾斜部材７との間の出入口方向Ａの間隙１０を塞ぐためのパッキン１１を傾斜部材７に一体に設けたことを特徴としており、このように構成することで、全閉状態にある引戸１の戸尻１ｂと袖壁２の先端との間には段差部６内に設けた傾斜部材７が存在することによって、引戸１の戸尻１ｂと袖壁２の先端との間に手指８を置いた場合でも、引戸１を開いた際には傾斜部材７に沿って手指８が外側に押し出され、これにより引戸１の戸尻１ｂによって手指８が挟まれる恐れがなく、怪我を未然に防止でき、安全に引戸１の開閉操作を行なうことができるうえに、段差部６による広い隙間が空いているものと比較して、引戸１の全閉状態での見栄えが極めて良くなる。
【０００８】
また上記全閉状態にある引戸１の戸尻１ｂと傾斜部材７との間の出入口方向Ａの間隙１０を塞ぐためのパッキン１１を傾斜部材７に一体に設けたので、パッキン１１によって引戸１の戸尻１ａの出入口方向Ａの密閉度を簡単且つ確実に高めることができる。
【０００９】
また上記傾斜部材７は、袖壁２の先端に取り付けられる取付片７ａと、該取付片７ａを開閉可能に隠蔽する傾斜片７ｂとを備え、該傾斜片７ｂは開放状態では取付片７ａを開放し且つ閉鎖状態では傾斜レール３Ａと略平行に傾斜した状態で取付片７ａを隠蔽するのが好ましく、この場合、傾斜片７ｂを開くことで取付片７ａを袖壁２に取り付ける操作が容易となり、傾斜片７ｂを閉じることで指詰め防止効果に加えて、取付片７ａを見栄え良く隠蔽できるようになる。
【００１０】
また上記引戸１の下端部に垂直軸Ｍ回りに回転可能な戸車１２を設けると共に、引戸１の上端部に上レール４にガイドされるガイド部材１３を後付け可能に取り付けるのが好ましく、この場合、最初に引戸１の戸車１２を下レール３に嵌め込み、その後、引戸１を立てかけてガイド部材１３を引戸１の上端部に後付けし、その後、ガイド部材１３を上レール４に嵌入させる取付方法を採用できる。つまり、従来のけんどん式を用いずに、垂直軸Ｍ回りに回転可能な戸車１２を下レール３に対して嵌め込むことが容易となり、しかも引戸１の上端部の隙間を小さくできるようになる。
【００１１】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１２】
図１は指詰め防止用の傾斜部材７を戸当たり部５から袖壁２の先端角部１５に至る段差部６内に設けた場合を示す平面図、図２は引戸１及び戸枠１４の斜視図、図３は引戸１の移動方向を説明する平面図である。
【００１３】
引戸１の戸枠１４は、図２に示すように、上枠１５と戸先側Ｃの縦枠１６と戸尻側Ｄの縦枠１７と中方立１８とで構成されており、戸先側Ｃの縦枠１６と中方立１８との間が出入口２６となっており、中方立１８と戸尻側Ｄの縦枠１７との間に袖壁２が設けられている。なお、戸尻側Ｄの縦枠１７は省略可能である。
【００１４】
ここで、上記引戸１は、図２、図３に示すように、全開状態では引戸１が袖壁２と略平行に対面する位置で保持され、閉じる直前には引戸１が傾斜レール３Ａに誘導されて出入口方向Ａに向かってカーブを描くように移動して、引戸１の戸先１ａが戸先側Ｃの縦枠１６に当たり且つ引戸１の戸尻１ｂが中方立１８の先端に設けた戸当たり部５に当たることで全閉状態での密閉度を高めるものである。
【００１５】
上記引戸１の上端部の少なくとも戸先側Ｃと戸尻側Ｄの２箇所には、図９に示す上レール４にガイドされるガイド部材１３が取り付けられている。上レール４は、引戸１のガイド部材１３を走行自在に且つ上下動可能にガイドする溝１９を有している。この溝１９は、後述する下レール３の直線レール及び傾斜レール３Ａにそれぞれ追随した形状で形成されている。
【００１６】
一方、引戸１の下端部の少なくとも戸先側Ｃと戸尻側Ｄの２箇所には、下レール３に支持される戸車１２が取り付けられている。下レール３は、図４に示すように、床溝２０に嵌め込まれる凹条部２１と、凹条部２１の幅方向中央から上方に向かって立設する凸条部２２と、凹条部２１の幅方向両端から上方に突出する左右一対のフランジ２３，２３とが一体形成されており、凸条部２２により戸車１２を支持する。なお図４の例では下レール３は床面２４より一段高くなっているが、床面２４と面一状にして段差なくすようにしてもよいものである。
【００１７】
さらに、下レール３は、図６（ａ）に示す戸先レール３０と図６（ｂ）に示す戸尻レール３１とに分けられている。戸先レール３０（戸尻レール３１も同様）は、図６（ａ）に示すように、出入口方向Ａと直交する方向に延びた直線レール３Ｂと、閉じる直前に引戸１を出入口方向Ａに移動させるために湾曲状に傾斜した傾斜レール３Ａとからなり、直線レール３Ｂと傾斜レール３Ａとの突き合わせ端部において互いに嵌合する凸状部３２と凹状部３３とによって各レール３Ａ，３Ｂが連結されると共に、各レール３Ａ，３Ｂは固定用孔３４において床にネジ固定されるようになっている。
【００１８】
ここにおいて、各傾斜レール３Ａは移動終端３５に向かって下り傾斜しており、引戸１全体を下り走行させて移動性を良好にしている。さらに傾斜レール３Ａの途中には突起部３６が突設されている。この突起部３６を戸車１２が乗り越えることにより引戸１が完全に閉まった際の感触を良好にすると共に、引戸１を全閉位置で安定して保持するものである。ここで、戸尻側Ｄの戸車１２が戸先側Ｃの戸車１２よりも早い段階で突起部３６を乗り越えることができるように、図６（ａ）（ｂ）のように各突起部３６の位置を所定ピッチΔＳ（＝Ｓ２−Ｓ１）だけずらせるのが望ましい。これにより、各戸車１２が同時に突起部３６を乗り越えることがないため、抵抗を小さくでき、そのうえ、戸先側Ｃの戸車１２が突起部３６を乗り越えたときには戸尻側Ｄの戸車１２は既に突起部３６を乗り越えた後であるため、戸先側Ｃへの引っ張り力だけで戸尻側Ｄの戸車１２が十分に移動できる構造となる。
【００１９】
次に、引戸１を開く際の指詰め防止構造を説明する。図１に示すように、引戸１の戸尻１ｂが当たる戸当たり部５を、中方立１８の先端角部１５よりも出入口方向Ａに入り込んだ位置に段差状に設けると共に、該戸当たり部５から中方立１８の先端角部１５に至る段差部６内に上記傾斜レール３Ａと略平行に傾斜した指詰め防止用の傾斜部材７を引戸１の戸尻１ｂに沿って上下方向の略全長に亘って設けたものである。本例の傾斜部材７は、戸当たり部５から中方立１８の先端角部１５に至る段差部６に沿って取り付けられる平面視でＬ字状の取付片７ａと、該取付片７ａの戸当たり部５側の一辺中央から中方立１８側の他辺先端に向かって延びる傾斜片７ｂとが樹脂成形品により一体形成されている。傾斜片７ｂは上述した傾斜レール３Ａと略平行に傾斜しており、引戸１を開く際に引戸１の戸尻１ｂと中方立１８との間に手指８が挟まれるのを防止する働きをする。さらに上記取付片７ａの戸当たり部５側の先端部分にはパッキン１１が突設され、全閉状態にある引戸１の戸尻１ｂと傾斜部材７との間の出入口方向Ａの間隙１０をパッキン１１にて塞ぐようにしている。パッキン１１は、引戸１の戸尻１ｂの上下方向の略全長に亘って設けられるものであり、２色成形によって傾斜部材７と一体成形されている。なお図１中の５０は化粧額縁である。
【００２０】
しかして、戸当たり部５から中方立１８の先端角部１５に至る段差部６内に傾斜部材７を設け、傾斜部材７の傾斜片７ｂを傾斜レール３Ａと略平行に傾斜させたことによって、全閉状態にある引戸１の戸尻１ｂと中方立１８の先端との間には段差部６内に設けた傾斜部材７が存在することなり、これによって、引戸１の戸尻１ｂと中方立１８との間に手指８（図１）を置いた場合でも、引戸１を開いた際には傾斜片７ｂに沿って手指８が外側（図１の矢印方向ａ）に押し出される。つまり、傾斜片７ｂは傾斜レール３Ａと略平行に傾斜しているため、閉じる直前での引戸１の戸尻１ｂの移動軌跡と傾斜片７ｂの傾斜方向とが略平行となり、引戸１の戸尻１ｂで手指８が挟まれる恐れがなく、怪我を未然に防止できるものである。しかも傾斜部材７を段差部６の上下方向の略全長に亘って設けることで、特に子供の怪我防止に役立ち、安全に引戸１の開閉操作を行なえるようになる。しかも、全閉状態にある引戸１の戸尻１ｂと中方立１８との間に傾斜部材７が存在することで、従来のように段差部６による隙間９（図１２）が広く空いているものと比較して、引戸１の全閉状態での見栄えが極めて良くなる。結果、傾斜部材７は、指詰め防止部材として機能するのみならず、意匠的に優れたものとする機能をも併せ持つようになる。
【００２１】
また本例の傾斜部材７には、全閉状態にある引戸１の戸尻１ｂとの出入口方向Ａの間隙１０を塞ぐためのパッキン１１が引戸１の戸尻１ｂの上下方向の全長に亘って設けられているので、引戸１の戸尻１ｂの出入口方向Ａの密閉度を簡単且つ確実に高めることができ、しかも、パッキン１１を傾斜部材７と一体成形したことで、パッキン１１を保持する専用の部品が不要となり、部品数増加を防止できるという利点もある。
【００２２】
図７、図８は傾斜部材７の他の実施形態を示している。本例では傾斜レール３Ａと略平行に傾斜している傾斜片７ｂを取付片７ａに対して開閉可能に設け、開放状態では取付片７ａを開放し且つ閉鎖状態では傾斜レール３Ａと略平行に傾斜した状態で取付片７ａを隠蔽するようにしている。ここでは傾斜片７ｂの基端部が薄肉状のヒンジ部５１を介して取付片７ａの一辺４０中央に連設され、傾斜片７ｂの先端部に設けた係合凸部５２が取付片７ａの他辺４１先端に設けた係合凹部５３に着脱可能に係合されている。そして、図８に示すように、傾斜片７ｂをヒンジ部５１を中心として手前に開くことで取付片７ａの他辺４１を取付ビス５４を用いて中方立１８に対して固定できるようになり、取付片７ａの取付操作が容易にできるものであり、その後、図７に示すように、傾斜片７ｂをヒンジ部５１を中心に閉じると係合凸部５２と係合凹部５３との凹凸係合によって傾斜片７ｂを傾斜レール３Ａと略平行に傾斜した状態で保持できるようになると共に、取付ビス５４を含む取付面７ｃを傾斜片７ｂによって見栄え良く隠蔽できるようになる。これにより、傾斜片７ｂは指詰め防止機能に加えて、取付片７ａを外部から見えなくする蓋体として機能も併せ持つようになる。また本例では傾斜部材７の先端部７ｄ（図７）は、中方立１８の先端角部１５よりも奥側Ａ１に入り込んだ位置に配置されている。しかして、傾斜片７ｂの基端部に薄肉のヒンジ部５１を設けることで、傾斜片７ｂを回動支持するための専用のヒンジ部材が不要となり、また傾斜片７ｂの先端部に設けた係合凸部５２を取付片７ａに設けた係合凹部５３に係合させる構造であるため、傾斜片７ｂを閉状態で保持するための専用の保持金具も不要となり、傾斜部材７の構造を簡略化できると共に製造コストを削減できるという利点もある。
【００２３】
図９は引戸１の上端部に設けられるガイド部材１３の他の実施形態を示している。本例では引戸１の上端部に対してガイド部材１３を後付け可能としている。
【００２４】
ちなみに、図１１に示すような従来の直線的に移動する引戸１では、引戸１の上端部を図１１の矢印イ方向から上レールに嵌め込み、その後、引戸１の下端部を図１１の矢印ロ方向に下げて下レールに嵌め込む、所謂けんどん式で据え付けるのが一般的であり、この場合、引戸１の上端部には隙間が生じないというメリットがある。しかし、本例のように閉じる直前に出入口方向Ａに移動させるタイプの引戸１の場合は、引戸１は戸先、戸尻での２箇所支持となるため、仮りにけんどん式で据え付ける場合は、引戸１の上端部に隙間が生じるという問題があり、そのうえ引戸１の下端部の戸車１２が垂直軸Ｍ（図５）回りに回転する場合においては、けんどん式で戸車１２を下レール３に嵌め込もうとするときに戸車１２が回転して嵌め込み作業が困難になるという問題もある。
【００２５】
そこで、本実施形態では、引戸１の上端部の少なくとも戸先側Ｃと戸尻側Ｄの２箇所にガイド部材１３をそれぞれ後付け可能とし、けんどん式とは異なる方法で引戸１を上下のレール３，４に対して取り付けるようにする。つまり、図９に示すように、ガイド部材１３は、上レール４の溝１９にスライド嵌合するピン６０と、ピン６０を支持する扁平形の支持ブロック６１とからなる。一方、引戸１の戸先１ａ側（戸尻１ｂ側も同様）の上端コーナー部には支持ブロック６１を前方から嵌め込むための側方（図９の矢印ニで示す方向）に開口した収納溝６２が形成され、収納溝６２に支持ブロック６１を側方から嵌め込み、側方からネジ６３で固定することで、ガイド部材１３を引戸１に対して後付けできるようにしている。なお、引戸１の下端部の少なくとも戸先側Ｃと戸尻側Ｄの２箇所には、垂直軸Ｍ回りに回転可能な戸車１２（図５（ｂ））が取り付けられているものとする。
【００２６】
しかして、本実施形態の引戸１を取り付ける一例を説明すると、先ず、図１０の矢印方向ハに向かって引戸１の戸車１２を下レール３に嵌め込み、その後引戸１を矢印方向ホに垂直に立てかける。しかる後に、図１０の矢印方向ニからガイド部材１３を引戸１の収納溝６２にそれぞれ嵌め込んで後付けする。つまり図９に示すガイド部材１３の支持ブロック６１を側方（図９の矢印ニで示す方向）から収納溝６２に嵌め込むと同時にピン６０を上レール４の溝１９の開口端から挿入する。その後、ネジ６３で支持ブロック６１を固定する。このような引戸１の取り付け方法によって、引戸１の下端部の戸車１２が垂直軸Ｍ回りに回転可能であっても下レール３に対して容易に嵌め込むことができ、しかも引戸１の上端部の隙間を極力小さくできるものである。なお、戸車１２は、下から押さえ付けられたときに下レール３の長手方向に向く構造とするのが望ましい。この場合、下レール３に対する戸車１２の嵌め込みが一層容易となる。
【００２７】
本発明に係る引戸の袖壁構造は、手動引戸のみならず電動引戸の分野にも広く適用可能である。
【００２８】
【発明の効果】
上述のように請求項１記載の発明にあっては、引戸が全開状態では袖壁と略平行に対面する位置で保持され、閉じる直前には傾斜レールに誘導されて出入口方向に移動して、引戸の戸尻が袖壁の先端に設けた戸当たり部に当たることで全閉状態での密閉度を高めるようにした引戸の袖壁構造において、引戸の戸尻が当たる戸当たり部を袖壁の先端角部よりも出入口方向に入り込んだ位置に段差状に設けると共に、該戸当たり部から袖壁の先端角部に至る段差部内に上記傾斜レールと略平行に傾斜した指詰め防止用の傾斜部材を設け、全閉状態にある引戸の戸尻と傾斜部材との間の出入口方向の間隙を塞ぐためのパッキンを傾斜部材に一体に設けたので、全閉状態にある引戸の戸尻と袖壁の先端との間には段差部内に設けた傾斜部材が存在することによって、引戸の戸尻と袖壁の先端との間に手指を置いた場合でも、引戸を開いた際には傾斜部材に沿って手指が外側に押し出され、これにより引戸の戸尻によって手指が挟まれる恐れがなく、怪我を未然に防止でき、安全に引戸の開閉操作を行なうことができると共に、全閉状態にある引戸の戸尻と中方立との間に傾斜部材が存在することで、従来のように段差部による隙間が広く空いているものと比較して、引戸の全閉状態での見栄えが極めて良くなり、安全性に加えて、意匠的向上を図ることができる。
【００２９】
さらに、上記全閉状態にある引戸の戸尻と傾斜部材との間の出入口方向の間隙を塞ぐためのパッキンを傾斜部材に一体に設けたので、パッキンによって引戸の戸尻の出入口方向の密閉度を簡単且つ確実に高めることができ、しかも、パッキンを傾斜部材と一体に設けたことで、パッキンを保持する専用の部品が不要となり、部品数増加を防止できるものである。
【００３０】
また請求項２記載の発明は、請求項１記載の効果に加えて、上記傾斜部材は、袖壁の先端に取り付けられる取付片と、該取付片を開閉可能に隠蔽する傾斜片とを備え、該傾斜片は開放状態では取付片を開放し且つ閉鎖状態では傾斜レールと略平行に傾斜した状態で取付片を隠蔽するのが好ましく、この場合、傾斜片を開くことで取付片を袖壁に取り付ける操作が容易となり、傾斜片を閉じることで指詰め防止効果に加えて、取付片を見栄え良く隠蔽でき、意匠性向上を図ることができる。
【００３１】
また請求項３記載の発明は、請求項１記載の効果に加えて、上記引戸の下端部に垂直軸回りに回転可能な戸車を設けると共に、引戸の上端部に上レールにガイドされるガイド部材を後付け可能に取り付けたので、最初に引戸の戸車を下レールに嵌め込み、その後、引戸を立てかけてガイド部材を引戸の上端部に後付けし、その後、ガイド部材を上レールに嵌入させる取付方法を採用でき、垂直軸回りに回転可能な戸車を下レールに対して嵌め込むことが容易となり、しかも引戸の上端部の隙間を小さくできるものであり、結果、従来のけんどん式を用いずに、開閉操作性の向上及び外観上の見栄え向上を一層図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a sleeve wall structure of a sliding door, and more particularly to a technique capable of preventing finger padding when opening a sliding door.
[0002]
[Prior art]
A general sliding door that moves linearly has a problem in that when it is closed, a gap is easily generated at the door tip, and sound insulation and sealing performance are poor.
[0003]
Therefore, conventionally, in the fully open state, the sliding door is held at a position facing the sleeve wall substantially in parallel, and immediately before closing, the sliding door is guided by the inclined rail and moves in the entrance / exit direction, so that the sliding door is on the door side. A structure is known in which the degree of sealing in a fully closed state is increased by hitting a vertical frame and the door butt of a sliding door hitting a door stop provided at the end of a sleeve wall (see, for example, Patent Document 1).
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 8-93308
[Problems to be solved by the invention]
By the way, in the type of sliding door that moves linearly, when opening the sliding door, fingers are not sandwiched between the door bottom of the sliding door and the sleeve wall, but as shown in FIG. In the case of the sliding door 1 of the type that moves in the doorway direction A immediately before closing, the door bottom 1b of the sliding door 1 can come into contact with the door stopper 5 without contacting the tip corner 15 of the sleeve wall 2 when closing. In order to do this, the door stop 5 is provided in a stepped shape at a position that enters the entrance / exit direction A from the tip corner 15 of the sleeve wall 2. For this reason, when the sliding door 1 is in the fully closed state due to the step portion 6 extending from the door stop portion 5 to the tip corner portion 15 of the sleeve wall 2, a wide gap is formed between the door butt 1 b of the sliding door 1 and the tip of the sleeve wall 2. When the finger is placed in the gap 9, the finger may be caught by the door butt 1b of the sliding door 1 when the sliding door 1 is opened in the arrow direction a of FIG. Note that reference numeral 50 in FIG. 12 denotes a makeup frame.
[0006]
The present invention was invented in view of the problems of the above-described conventional example, and the object of the present invention is to safely remove the sliding door without fear of being pinched by the door butt of the sliding door when opening the sliding door. The object of the present invention is to provide a sliding door sleeve wall structure that can be opened and closed and can improve the appearance of the sliding door in a fully closed state. The purpose of the present invention is to provide a sleeve wall structure of a sliding door that can easily and reliably increase the degree of sealing in a direction. Another object is to improve the appearance while facilitating the mounting operation of the inclined member. The purpose of the sliding door sleeve wall structure is to provide a sliding door structure, and yet another purpose is to improve the appearance and reduce the gap at the upper end of the sliding door without using the conventional tendon type. To further improve It is to provide a sleeve wall structure of the sliding door that can be.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, the sliding door 1 is held in a position facing the sleeve wall 2 substantially in parallel with the fully closed state, and is guided by the inclined rail 3A immediately before the sliding door 1 in the entrance / exit direction A. In the sliding wall structure of the sliding door, the door bottom 1b of the sliding door 1 is improved in that the door bottom 1b of the sliding door 1 hits the door stop 5 provided at the tip of the sleeve wall 2 to enhance the sealing degree in the fully closed state. The door contact portion 5 to which 1b hits is provided in a stepped shape at a position entering the entrance / exit direction A from the front end corner portion 15 of the sleeve wall 2 and the step portion 6 extending from the door end portion 5 to the front end corner portion 15 of the sleeve wall 2. An inclining member 7 for preventing finger filling that is inclined substantially parallel to the inclining rail 3A is provided in the inside, and the gap 10 in the doorway direction A between the door butt 1b of the sliding door 1 and the inclining member 7 in the fully closed state is closed. as characterized by providing integrally with the packing 11 to the inclined member 7 for With this configuration, the inclined member 7 provided in the stepped portion 6 exists between the door bottom 1b of the sliding door 1 in the fully closed state and the end of the sleeve wall 2, so that the sliding door 1 Even when the finger 8 is placed between the door butt 1b and the tip of the sleeve wall 2, when the sliding door 1 is opened, the finger 8 is pushed out along the inclined member 7, so that the door of the sliding door 1 is opened. There is no risk of fingers 8 being pinched by the butt 1b, injury can be prevented in advance, the sliding door 1 can be opened and closed safely, and compared with a case where a wide gap by the step 6 is open, The appearance of the sliding door 1 in the fully closed state is extremely improved.
[0008]
In addition, since the packing 11 for closing the gap 10 in the doorway direction A between the door butt 1b of the sliding door 1 in the fully closed state and the inclined member 7 is provided integrally with the inclined member 7 , the packing 11 The degree of sealing in the doorway direction A of the door bottom 1a can be easily and reliably increased.
[0009]
The inclined member 7 includes an attachment piece 7a attached to the tip of the sleeve wall 2 and an inclination piece 7b that conceals the attachment piece 7a so that the attachment piece 7a can be opened and closed. The inclination piece 7b opens the attachment piece 7a in an open state. In the closed state, it is preferable to conceal the attachment piece 7a while being inclined substantially parallel to the inclined rail 3A. In this case, the operation of attaching the attachment piece 7a to the sleeve wall 2 is facilitated by opening the inclined piece 7b. By closing the inclined piece 7b, the attachment piece 7a can be concealed with good appearance in addition to the effect of preventing finger filling.

First, the door 12 of the sliding door 1 is fitted into the lower rail 3, and then the sliding door 1 is erected, the guide member 13 is retrofitted to the upper end of the sliding door 1, and then the guide member 13 is fitted into the upper rail 4. it can. That is, it becomes easy to fit the door wheel 12 that can rotate around the vertical axis M into the lower rail 3 without using the conventional tendon type, and the gap at the upper end of the sliding door 1 can be reduced. .
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.
[0012]
FIG. 1 is a plan view showing a case where an inclined member 7 for preventing finger filling is provided in a stepped portion 6 from the door stop portion 5 to the tip corner portion 15 of the sleeve wall 2, and FIG. 2 shows the sliding door 1 and the door frame 14. FIG. 3 is a plan view for explaining the moving direction of the sliding door 1.
[0013]
As shown in FIG. 2, the door frame 14 of the sliding door 1 includes an upper frame 15, a vertical frame 16 on the door-end side C, a vertical frame 17 on the door-end side D, and a neutral stand 18. An entrance 26 is provided between the C vertical frame 16 and the neutral stand 18, and the sleeve wall 2 is provided between the neutral stand 18 and the vertical frame 17 on the door-side D. The vertical frame 17 on the door bottom side D can be omitted.
[0014]
Here, as shown in FIGS. 2 and 3, the sliding door 1 is held in a position where the sliding door 1 faces substantially parallel to the sleeve wall 2 in the fully opened state, and the sliding door 1 is guided to the inclined rail 3A immediately before closing. The door 1a of the sliding door 1 hits the vertical frame 16 on the door side C and the door butt 1b of the sliding door 1 is provided at the tip of the neutral 18 By hitting the contact portion 5, the degree of sealing in the fully closed state is increased.
[0015]
Guide members 13 guided by the upper rail 4 shown in FIG. 9 are attached to at least two locations on the upper end portion of the sliding door 1 on the door end side C and the door bottom side D. The upper rail 4 has a groove 19 that guides the guide member 13 of the sliding door 1 so that it can run and move up and down. The groove 19 is formed in a shape that follows a straight rail and an inclined rail 3A of the lower rail 3 described later.
[0016]
On the other hand, doors 12 supported by the lower rail 3 are attached to at least two locations on the lower end of the sliding door 1, the door end side C and the door bottom side D. As shown in FIG. 4, the lower rail 3 includes a concave strip portion 21 fitted into the floor groove 20, a convex strip portion 22 erected upward from the center in the width direction of the concave strip portion 21, and the concave strip portion 21. A pair of left and right flanges 23, 23 projecting upward from both ends in the width direction are integrally formed, and the door 12 is supported by the ridge 22. In the example of FIG. 4, the lower rail 3 is one step higher than the floor surface 24. However, the lower rail 3 may be flush with the floor surface 24 so that there is no step.
[0017]
Further, the lower rail 3 is divided into a door end rail 30 shown in FIG. 6A and a door bottom rail 31 shown in FIG. 6B. As shown in FIG. 6A, the door end rail 30 (same as the door bottom rail 31) moves the sliding door 1 in the entrance / exit direction A just before closing, and the straight rail 3B extending in the direction orthogonal to the entrance / exit direction A. The rails 3A and 3B are connected by a convex portion 32 and a concave portion 33 which are fitted to each other at the abutting end portion of the linear rail 3B and the inclined rail 3A. At the same time, the rails 3A and 3B are screwed to the floor in the fixing holes 34.
[0018]
Here, each inclined rail 3 </ b> A is inclined downward toward the moving terminal end 35, and the entire sliding door 1 travels downward to improve the mobility. Further, a protrusion 36 is provided in the middle of the inclined rail 3A. When the door 12 gets over the protrusion 36, the touch when the sliding door 1 is completely closed is improved, and the sliding door 1 is stably held in the fully closed position. Here, as shown in FIGS. 6 (a) and 6 (b), the doors 12 on the door bottom side D can get over the protrusions 36 at an earlier stage than the door wheel 12 on the door end side C. It is desirable to shift the position by a predetermined pitch ΔS (= S2−S1). Accordingly, each door 12 does not get over the protrusion 36 at the same time, so that the resistance can be reduced. Moreover, when the door 12 on the door end side C gets over the protrusion 36, the door 12 on the door end D already protrudes. Since it is after getting over the part 36, it becomes a structure where the door pulley 12 of the door bottom side D can move enough only by the pulling force to the door end side C.
[0019]
Next, a structure for preventing finger filling when the sliding door 1 is opened will be described. As shown in FIG. 1, the door stop portion 5 against which the door butt 1 b of the sliding door 1 hits is provided in a stepped shape at a position that enters the entrance / exit direction A from the tip corner portion 15 of the neutral stand 18, and the door stop portion 5 A tilting member 7 for preventing finger padding, which is tilted substantially parallel to the tilted rail 3A, in the stepped portion 6 extending from the central corner 18 to the tip corner 15 of the sliding door 1 along the door butt 1b of the sliding door 1 has a substantially total length in the vertical direction. It is provided over. The inclined member 7 of this example includes an L-shaped attachment piece 7a attached along the step portion 6 extending from the door stop portion 5 to the tip corner portion 15 of the neutral stand 18, and the door contact of the attachment piece 7a. An inclined piece 7b extending from the center of one side of the part 5 side toward the tip of the other side of the neutral 18 side is integrally formed of a resin molded product. The inclined piece 7b is inclined substantially parallel to the inclined rail 3A described above, and serves to prevent the fingers 8 from being caught between the door butt 1b of the sliding door 1 and the neutral stand 18 when the sliding door 1 is opened. . Further, a packing 11 protrudes from the tip of the mounting piece 7a on the door contact portion 5 side, and a gap 10 in the doorway direction A between the door butt 1b of the sliding door 1 and the inclined member 7 in the fully closed state is packed. 11 to close. The packing 11 is provided over substantially the entire vertical length of the door butt 1b of the sliding door 1, and is integrally formed with the inclined member 7 by two-color molding. Note that reference numeral 50 in FIG. 1 denotes a makeup frame.
[0020]
Thus, the inclined member 7 is provided in the step portion 6 from the door stop portion 5 to the tip corner portion 15 of the neutral stand 18, and the inclined piece 7b of the inclined member 7 is inclined substantially parallel to the inclined rail 3A. Between the door butt 1b of the sliding door 1 in the fully-closed state and the tip of the neutral stand 18, there is an inclined member 7 provided in the step portion 6, and thereby the door butt 1b of the sliding door 1 and the neutral stand Even when the finger 8 (FIG. 1) is placed between the finger 18 and the sliding door 1 is opened, the finger 8 is pushed outward along the inclined piece 7b (arrow direction a in FIG. 1). That is, since the inclined piece 7b is inclined substantially in parallel with the inclined rail 3A, the movement locus of the door butt 1b of the sliding door 1 immediately before closing and the inclination direction of the inclined piece 7b are substantially parallel, and the door butt of the sliding door 1 is obtained. There is no fear of the fingers 8 being pinched by 1b, and injuries can be prevented in advance. In addition, by providing the inclined member 7 over substantially the entire length of the step portion 6 in the vertical direction, it is particularly useful for preventing children from being injured and the sliding door 1 can be opened and closed safely. Moreover, since the inclined member 7 exists between the door butt 1b of the sliding door 1 in the fully closed state and the neutral stand 18, the gap 9 (FIG. 12) by the step portion 6 is wide as in the prior art. Compared with, the appearance in the fully-closed state of the sliding door 1 becomes very good. As a result, the inclined member 7 not only functions as a finger padding preventing member but also has a function that makes it excellent in design.
[0021]
Further, in the inclined member 7 of this example, a packing 11 for closing the gap 10 in the doorway direction A with the door butt 1b of the sliding door 1 in the fully closed state extends over the entire length of the door butt 1b of the sliding door 1 in the vertical direction. Since it is provided, the degree of sealing in the doorway direction A of the door butt 1b of the sliding door 1 can be easily and reliably increased, and the packing 11 is integrally formed with the inclined member 7, so that the packing 11 is held exclusively. There is also an advantage that an increase in the number of parts can be prevented.
[0022]
7 and 8 show another embodiment of the inclined member 7. In this example, an inclined piece 7b inclined substantially parallel to the inclined rail 3A is provided so as to be openable and closable with respect to the attachment piece 7a. The attachment piece 7a is opened in the open state and inclined substantially parallel to the inclined rail 3A in the closed state. In this state, the attachment piece 7a is concealed. Here, the base end portion of the inclined piece 7b is connected to the center of one side 40 of the attachment piece 7a via the thin-walled hinge portion 51, and the engagement convex portion 52 provided at the distal end portion of the inclined piece 7b is the attachment piece 7a. It is detachably engaged with an engagement recess 53 provided at the tip of the other side 41. And, as shown in FIG. 8, the other side 41 of the mounting piece 7 a can be fixed to the neutral 18 using the mounting screw 54 by opening the inclined piece 7 b forward with the hinge portion 51 as the center, The mounting operation of the mounting piece 7a can be easily performed, and thereafter, as shown in FIG. 7, when the inclined piece 7b is closed around the hinge portion 51, the concave and convex engagement between the engaging convex portion 52 and the engaging concave portion 53 is achieved. As a result, the inclined piece 7b can be held in an inclined state substantially parallel to the inclined rail 3A, and the attachment surface 7c including the attachment screw 54 can be concealed with good appearance by the inclined piece 7b. Thereby, in addition to the finger filling prevention function, the inclined piece 7b also has a function as a lid that makes the attachment piece 7a invisible from the outside. Further, in this example, the distal end portion 7 d (FIG. 7) of the inclined member 7 is disposed at a position entering the back side A <b> 1 from the distal end corner portion 15 of the neutral stand 18. Thus, by providing the thin hinge portion 51 at the base end portion of the inclined piece 7b, a dedicated hinge member for rotating and supporting the inclined piece 7b becomes unnecessary, and the engagement provided at the distal end portion of the inclined piece 7b. Since the mating convex portion 52 is engaged with the engaging concave portion 53 provided on the mounting piece 7a, a dedicated holding bracket for holding the inclined piece 7b in the closed state is not required, and the structure of the inclined member 7 is simplified. There is also an advantage that the manufacturing cost can be reduced.
[0023]
FIG. 9 shows another embodiment of the guide member 13 provided at the upper end of the sliding door 1. In this example, the guide member 13 can be retrofitted to the upper end of the sliding door 1.
[0024]
Incidentally, in the conventional sliding door 1 that moves linearly as shown in FIG. 11, the upper end of the sliding door 1 is fitted into the upper rail from the direction of the arrow A in FIG. 11, and then the lower end of the sliding door 1 is moved to the arrow B in FIG. In general, it is installed in a so-called kendon type that is lowered in the direction and fitted into the lower rail. In this case, there is an advantage that no gap is formed at the upper end of the sliding door 1. However, in the case of the sliding door 1 of the type that is moved in the entrance / exit direction A just before closing as in this example, the sliding door 1 is supported at two locations at the door tip and the door butt, so if it is temporarily installed in the form When the door 12 at the lower end of the sliding door 1 rotates about the vertical axis M (FIG. 5), the door 12 is moved to the lower rail 3 by the noodle type. There is also a problem that when the door 12 is rotated, the door 12 rotates and the fitting operation becomes difficult.
[0025]
Therefore, in this embodiment, the guide members 13 can be retrofitted at least at the two positions of the upper end portion of the sliding door 1 on the door end side C and the door bottom side D, and the sliding door 1 is mounted on the upper and lower rails by a method different from the Kendon type. Attach to 3 and 4. That is, as shown in FIG. 9, the guide member 13 includes a pin 60 that is slidably fitted in the groove 19 of the upper rail 4 and a flat support block 61 that supports the pin 60. On the other hand, the storage groove opened in the side (direction shown by the arrow D of FIG. 9) for fitting the support block 61 into the upper end corner portion of the door 1a side of the sliding door 1 (the same applies to the door butt 1b side). 62 is formed, and the guide block 13 can be retrofitted to the sliding door 1 by fitting the support block 61 into the storage groove 62 from the side and fixing it with the screw 63 from the side. In addition, the door pulley 12 (FIG.5 (b)) which can be rotated to the periphery of the vertical axis | shaft M shall be attached to at least two places of the lower end part of the sliding door 1 of the door tip side C and the door bottom side D. FIG.
[0026]
Thus, an example of attaching the sliding door 1 of the present embodiment will be described. First, the door 12 of the sliding door 1 is fitted into the lower rail 3 in the direction indicated by the arrow C in FIG. 10, and then the sliding door 1 is stood perpendicularly to the arrow direction e. . Thereafter, the guide members 13 are fitted into the storage grooves 62 of the sliding door 1 from the direction indicated by the arrow in FIG. That is, the support block 61 of the guide member 13 shown in FIG. 9 is fitted into the storage groove 62 from the side (the direction indicated by the arrow D in FIG. 9), and at the same time, the pin 60 is inserted from the opening end of the groove 19 of the upper rail 4. Thereafter, the support block 61 is fixed with the screws 63. By such a mounting method of the sliding door 1, even if the door wheel 12 at the lower end of the sliding door 1 can rotate around the vertical axis M, it can be easily fitted into the lower rail 3, and the upper end of the sliding door 1. The gap can be made as small as possible. It is desirable that the door pulley 12 has a structure that faces the longitudinal direction of the lower rail 3 when pressed from below. In this case, the door 12 can be fitted into the lower rail 3 more easily.
[0027]
The sleeve wall structure of the sliding door according to the present invention can be widely applied not only to the manual sliding door but also to the electric sliding door field.
