Description

【０００１】
【発明の属する技術分野】
本発明は、建物の躯体の開口部に配設される引き戸装置に関するものであり、詳しくは、引き戸の開放操作及び開放姿勢が効果的に維持される引き戸装置に関するものである。
【０００２】
【従来の技術】
従来、建物の開口部に配置される引き戸装置は、使用者が通過した後、引き戸が開放されたままにならないよう、引き戸が自動的に閉鎖する自閉機能を有するものが多く採用されている。
一方、人の出入りの多い個所や室内の様子を観察する必要のある個所（特に病室等）においては、その都度、引き戸を開放する煩わしさを解消する為、さらに、室内の通気が必要な時、自閉機能に付加して引き戸の全開状態を維持する全開ストッパー機能（引き戸が全開位置で停止し、自閉しなくなる機能。）も必要であった。
【０００３】
そして、従来の全開ストッパー機能は、図９に示すように、引き戸１ａの戸先側上部に設けられた山形のストッパー受け２ａと、固定側部材３ａに上下方向で取付位置を高さ調節自在とした取付座６ａと、先端にローラー４ａを回転自在に有し、取付座６ａに連結された弾性ストッパー５ａより構成され、引き戸１ａを全開位置まで開放させると、ストッパー受け２ａで弾性に抗して上方に押しやられた（第９図仮想線に示す状態。）弾性ストッパー５ａのローラー４ａが頂部７ａの戸先側に位置し、全開ストパー部８ａに弾性的に当接する事により、引き戸１ａを全開位置で停止させる（図９の実線で示す状態。）ものであった。
【０００４】
しかしながら上記構成によると、勢いよく引き戸１ａが開かれると、全開時、引き戸１ａの戸尻側端部が開放側の縦枠に衝突し、その跳ね返りでストッパー受け２ａが弾性ストッパー５ａを再度上方に押しやって通過し、その後自閉機能によって、引き戸１ａが閉鎖する事があった。
これを防止する為、弾性ストッパー５ａの弾性を強くすると（取付座６ａを下方に調節すると）、全開位置で停止している引き戸１ａを閉鎖させる時（第９図の実線で示す状態から矢印方向に引き戸１ａを移動させる時）、ストッパー受け２ａが弾性ストッパー５ａを弾性に抗して上方に押しやる必要があるので、高齢者、或いは疾病者にとって操作力が非常に重くなり使いづらくなる問題があった。
一方、高齢者、或いは疾病者でも使いやすいように、弾性ストッパー２ａの弾性を弱めに設定すると（取付座６ａを上方に調節して固定座部材３ａに取付）、引き戸１ａが跳ね返らないよう、引き戸１ａに最後まで手を添えて全開させなければならなかった。
【０００５】
しかしながら、引き戸１ａの全開位置は、人の通過巾以上の大きさに設定されているので、車椅子の使用者、高齢者、或いは疾病者にとって引き戸１ａに手を添えてを全開位置まで移動させる事、更に全開位置の引き戸１ａを閉鎖させる為、引き戸１ａに手が届く位置まで移動するのは非常に煩わしい問題であった。
【０００６】
【発明が解決しようとする課題】
本発明は上記問題に鑑みてなされたものであり、簡単な構造で、引き戸を勢いよく開放しても、全開時の反動で閉鎖する事がなく、全開状態（開放状態）の引き戸も軽く閉鎖させる事が可能で、車椅子の使用者、高齢者、或いは疾病者であっても、容易に引き戸を開放状態に維持出来る画期的な引き戸装置を提供する事を目的とする。
【０００７】
【課題を解決する為の手段】
そこで、上記課題を解決する為、本発明の第１の手段として構成したところは、点検カバーにより開閉自在な開口を有する空間内部に設けた引き戸レールに沿って自閉可能とした引き戸装置において、前記点検カバーを開口したとき該開口が臨む位置に、引き戸と共に移動するように該引き戸に設けたストッパー受けと、固定側に設けた弾性ストッパーを配置しており、前記弾性ストッパーは、前記ストッパー受けに向けて突出する弾性脚体の端部にローラーを設けており、前記ストッパー受けは、開方向の移動に関して引き戸が少なくとも車椅子の通過巾以上開放されたとき前記ローラーの接触を受けて引き戸の移動を制動するが引き戸が全開状態となったときローラーの接触状態を解除する長さに形成された制動部と、該制動部の戸尻側端部に傾斜して突出する案内部と、該制動部の戸先側端部に前記案内部よりも急激に傾斜して突出することにより引き戸の全開位置を維持する全開ストッパー部とを構成しており、前記弾性ストッパーの弾性脚体は、ローラーを制動部に対して引き戸の自閉力よりも強く弾性的に当接するように構成され、開方向の移動に関して引き戸を少なくとも車椅子の通過巾以上で全開位置に至らない開放途中位置まで移動したとき、ローラーが案内部を経て制動部に当接することにより引き戸を自閉しないように停止可能とする一方、引き戸を勢いよく開放移動することにより引き戸が全開位置から跳ね返ったとき、全開ストッパー部を乗り越えたローラーが制動部に当接することにより少なくとも車椅子の通過巾以上の出入り口を確保した状態で引き戸を自閉せず停止するように構成されている点にある。
【０００８】
次に本発明が第２の手段として構成したところは、点検カバーにより開閉自在な開口を有する空間内部に設けた引き戸レールに沿って自閉可能とした引き戸装置において、前記点検カバーを開口したとき該開口が臨む位置に、引き戸と共に移動するように該引き戸に設けた弾性ストッパーと、固定側に設けたストッパー受けを配置しており、前記弾性ストッパーは、前記ストッパー受けに向けて突出する弾性脚体の端部にローラーを設けており、前記ストッパー受けは、開方向の移動に関して引き戸が少なくとも車椅子の通過巾以上開放されたとき前記ローラーの接触を受けて引き戸の移動を制動するが引き戸が全開状態となったときローラーの接触状態を解除する長さに形成された制動部と、該制動部の戸尻側端部に傾斜して突出する案内部と、該制動部の戸先側端部に前記案内部よりも急激に傾斜して突出することにより引き戸の全開位置を維持する全開ストッパー部とを構成しており、前記弾性ストッパーの弾性脚体は、ローラーを制動部に対して引き戸の自閉力よりも強く弾性的に当接するように構成され、開方向の移動に関して引き戸を少なくとも車椅子の通過巾以上で全開位置に至らない開放途中位置まで移動したとき、ローラーが案内部を経て制動部に当接することにより引き戸を自閉しないように停止可能とする一方、引き戸を勢いよく開放移動することにより引き戸が全開位置から跳ね返ったとき、全開ストッパー部を乗り越えたローラーが制動部に当接することにより少なくとも車椅子の通過巾以上の出入り口を確保した状態で引き戸を自閉せず停止するように構成されている点にある。
【０００９】
次に本発明が第３の手段として構成したところは、弾性ストッパーは、板バネ材から形成され、ストッパー受け方向に突出する弾性脚体と、弾性脚体のストッパー受け側の端部に形成されたローラー取付座と、ローラー取付座に回転自在に取付られるゴム製あるいは合成樹脂製のローラーより構成されているものである。
【００１０】
【実施例】
以下、本発明を図面に基づいて説明する。
図１〜図４は、第１の実施例を示している。
引き戸装置１は、建物側の鉄骨にブラケットを介して固定された戸先側縦枠及び戸尻側縦枠と、戸先側縦枠及び戸尻側縦枠の上端部間に配設され、建物側鉄骨にブラケットを介して固定された上横枠１１より構成され、建物の開口部内に配設された引き戸枠と、上横枠１１の下方に位置し、戸先側縦枠と戸尻側縦枠の上部間に戸先側縦枠側が低くなるよう高さ調節可能に配設され、引き戸レール１２が取付られるレール取付材１３と、戸先側縦枠と戸尻側縦枠間で、上端がレール取付材１３の室内外側の両面に固定され、下端部が床面に埋め込まれて配設され、戸先側縦枠間とで建物の開口部に出入り口１０を形成する中枠１４、１４と、レール取付材１３の室外側の表面で出入り口１０の上部に取り付けられるランマ下地パネル１５と、レール取付材１３の室内側の表面で出入り口１０の上部に、室内側下地材１６を介して、着脱自在に取付られる点検パネル１７と、引き戸レール１２の吊り座１８に、吊り金具１９、吊りボルト１９１を介して吊り下げられる引き戸２等より構成されている。
【００１１】
符号３・・・は、ランマ下地パネル１５、室内側下地材１６の表面に、建物の壁面の化粧ボードと面一に貼設された化粧ボードを示し、符号５はレール取付材１３に取付高さ調節自在に連結されたストッパー取付座５０に取付られた弾性ストッパーを示し、符号６は引き戸２に取付られたストッパー受けを示している
尚、実施例１の引き戸装置１は、全開時に引き戸２が位置するいわゆる戸袋部分は、壁面の化粧ボードと面一に化粧ボードで隠蔽されているので、出入り口１０及び点検パネル１７を開口した個所より調節が可能なように、ストッパー受け６は、引き戸２の戸先側上端部に、これに対応して弾性ストッパー５は、出入り口１０の上端部中枠１４に位置するよう設けられている。
【００１２】
ストッパー受け６は、引き戸２に連結される連結突片６１と、連結突片６１の上端で外方に突出し、引き戸レール１２と平行に位置する所定長さ（引き戸２が少なくとも車椅子の通過巾以上開放された時、弾性ストッパー５の後記するローラー５４が接触し、引き戸２が全開状態となった時ローラー５４の接触状態が解除される長さ）の制動部６２と、制動部６２の戸尻側端部に傾斜して下方に突出する案内部６３と、制動部６２の戸先側端部に案内部６３より急激に傾斜して下方突出する全開ストッパー部６４より形成されている。
【００１３】
弾性ストッパー５は板バネ材からなり、ストッパー取付座５０の下面に連結される連結部５１と、連結部５１の戸先側端部から傾斜してストッパー受け６の方向に突出する弾性脚体５２と、弾性脚体５２のストッパー受け６側の端部に形成されたローラー取付座５３と、ローラー取付座５３に回転自在に取付られるゴム製あるいは合成樹脂製のローラー５４より構成され、弾性ストッパー５のローラー５４は、開放途中で前記制動部６２に、引き戸２の自閉力（第１実施例では、引き戸レール１２が閉鎖方向に下がるように傾斜して配設された事による自閉力）より強く弾性的に当接している。
【００１４】
第１実施例は、以上の構成であるので、引き戸２が勢いよく開放されても、弾性ストッパー５のローラー５４にストッパー受け６の制動部６２が達すると、ローラー５４は制動部６２に対して引き戸２の自閉力よりも強く弾性的に当接するので、引き戸２の開放運動にブレーキが掛かかる一方、引き戸２の跳ね返りの閉鎖運動でもブレーキがかかるので、前者のブレーキにより、ローラー５４が全開ストッパー部６４の戸先側に当接して引き戸２の全開位置を維持するか、或いは、後者のブレーキにより、跳ね返り後に、少なくとも、車椅子の通過巾以上の出入り口を確保した状態で引き戸２が停止する。
【００１５】
すなわち、引き戸２は、少なくとも車椅子の通過巾以上の開放途中で、制動部６２にローラー５４が当接することにより、自閉を阻止され、停止できるので、車椅子使用者或いは疾病者が、引き戸２を開放状態で停止させておく操作をする時も、又、停止した引き戸２を閉鎖する時も軽い開閉力で行うことが出来る。その一方において、健常者が引き戸１２を開放姿勢で停止させるのに勢いよく引き戸２を開放しても、制動部６２の二重のブレーキ効果により、出入り口１０を確実に確保した状態で引き戸２を停止させておくことが出来るので、最後まで引き戸に手を添えて開放させる必要もない。すなわち、健常者或いは車椅子使用者等の異なった開放力に柔軟に対応する事が出来る。
【００１６】
次に第２実施例を図５、６、７、８に基づいて説明する。
第２実施例の引き戸装置１は、建物の壁面に形成された開口部を出入り口１０とし、この出入り口１０の外側に引き戸２を開閉自在に設けたものである。
引き戸装置１は、建物の鉄骨にブラケット等を介して連結された上横枠１１と、出入り口１０内におさめられ、一部が上横枠１１と連結され三方枠１１１と、、横枠１１の所定位置に引き戸２の開閉方向に沿って複数個構成された取付座１１２・・・にボルト１１３を介して戸先側が低くなるよう高さ調節自在に取付られた、引き戸レール１２が取付られたレール取付材１３と、引き戸レール１２の吊り座１８に吊り金具１９、連結ピン１９１を介して吊り下げられた引き戸２と、引き戸２の上端部及びレール取付材１３等を着脱自在に隠蔽する点検カバー１７等より構成されている。
【００１７】
そして、第２実施例の弾性ストッパー５は、引き戸２と共に移動する吊り座１８にストッパー取付座５０を介して取付られ、ストッパー受け６は、弾性ストッパー５の位置に対応して、レール取付材１３に取付られている。
すなわち、ストッパー受け６は、レール取付材１３に連結される連結される連結突片６１と、連結突片６１の下端で引き戸レール１２側に突出し、引き戸レール１２と平行に位置する所定長さ（引き戸２が少なくとも車椅子の通過巾以上開放された時、引き戸２と共に移動する弾性ストッパー５の後記するローラー５４が接触し、引き戸２が全開状態となった時ローラー５４の接触状態が解除される長さ）の制動部６２と、制動部６２の閉鎖側端部に傾斜して引き戸レール１２の反対方向に突出する案内部６３と、制動部６２の開放側端部に案内部６３より急激に傾斜して引き戸レール１２の反対方向に突出する全開ストッパー部６４より形成されている。
【００１８】
又、第２実施例の弾性ストッパー５は板バネ材からなり、ストッパー取付座５０の引き戸レール１２の反対側面に連結される連結部５１と、連結部５１の戸尻側端部から傾斜してストッパー受６け方向に突出する弾性脚体５２と、弾性脚体５２のストッパー受け６側の端部に形成されたローラー取付座５３と、ローラー取付座５３に回転自在に取付られるゴム製、あるいは合成樹脂製のローラー５４より構成され、弾性ストッパー５のローラー５４は、開放途中で前記制動部６２に、引き戸２の自閉力（第２実施例では、実公平３−２１４２０号に記載された自閉装置による引き戸２自閉力、すなわち、錘体によって常時閉鎖方向に走行力が付与された引き戸２の自閉力）より強く弾性的に当接している。
【００１９】
第２実施例は、以上の構成であるので、引き戸２が勢いよく開放されても、弾性ストッパー５のローラー５４がストッパー受け６の制動部６２に達すると、ローラー５４は制動部６２に対して引き戸２の自閉力よりも強く弾性的に当接するので、引き戸２の開放運動にブレーキが掛かかる一方、引き戸２の跳ね返りの閉鎖運動でもブレーキがかかるので、前者のブレーキにより、ローラー５４が全開ストッパー部６４の開放側に当接して引き戸２の全開位置を維持するか、或いは、後者のブレーキにより、跳ね返り後に、少なくとも、車椅子の通過巾以上の出入り口を確保した状態で引き戸２が停止する。
【００２０】
すなわち、引き戸２は、少なくとも車椅子の通過巾以上の開放途中で、制動部６２にローラー５４が当接することにより、自閉を阻止され、停止できるので、車椅子使用者或いは疾病者が、引き戸２を開放状態で停止させておく操作をする時も、又、停止した引き戸２を閉鎖する時も軽い開閉力で行うことが出来る。その一方において、健常者が引き戸１２を開放姿勢で停止させるのに勢いよく引き戸２を開放しても、制動部６２の二重のブレーキ効果により、出入り口１０を確実に確保した状態で引き戸２を停止させておくことが出来るので、最後まで引き戸に手を添えて開放させる必要もない。すなわち、健常者或いは車椅子使用者等の異なった開放力に柔軟に対応する事が出来る。
【００２１】
【発明の効果】
請求項１及び請求項２に記載の発明によれば、引き戸２を少なくとも車椅子の通過巾以上開放し全開位置に至らない状態で、弾性ストッパー５のローラー５４をストッパー受け６の案内部６３を経て制動部６２に弾性的に当接するように構成し、その際、その弾性的当接を引き戸２の自閉力よりも強くなるように構成しており、該制動部 (62) の戸尻側端部に傾斜して突出する案内部 (63) を設け、該制動部 (62) の戸先側端部に前記案内部 (63) よりも急激に傾斜して突出する全開ストッパー部 (64) を設けている。従って、引き戸２を開放途中位置（少なくとも車椅子の通過巾以上で全開位置に至らない位置）まで移動したとき、案内部６３を経て制動部６２に当接するローラー５４のブレーキ作用で引き戸２の自閉を阻止することにより停止できるので、車椅子の使用者、高齢者、或いは疾病者であっても、容易に引き戸を開放状態に維持する事ができ、しかも、軽い開閉力で操作することができる。更に、健常者が引き戸２を勢いよく開放移動し、引き戸２が全開位置から跳ね返るような場合でも、全開ストッパー部６４を乗り越えたローラー５４と制動部６２のブレーキ作用で少なくとも車椅子の通過巾以上の出入り口を確保した状態で引き戸２の自閉を阻止し停止させる事ができるので、全開時の反動で閉鎖する事がないという効果がある。
又、請求項３に記載の発明によればストッパー受けと弾性ストッパーの当接部にゴム製あるいは合成樹脂製のローラを使用しているので、引き戸の開閉時にストッパー受けと弾性ストッパーの衝突音が発生せず、特に病室等の静寂さを要求されるところには適している。

BACKGROUND OF THE INVENTION
The present invention relates to a sliding door device disposed in an opening of a building frame, and more particularly to a sliding door device in which the opening operation and the opening posture of the sliding door are effectively maintained.
[0002]
[Prior art]
Conventionally, many sliding door devices arranged at the opening of a building have a self-closing function that automatically closes the sliding door so that the sliding door does not remain open after the user passes. .
On the other hand, in places where there is a lot of people coming and going and places where it is necessary to observe the state of the room (especially hospital rooms, etc.), in order to eliminate the hassle of opening the sliding door each time, further ventilation of the room is necessary. In addition to the self-closing function, a fully-open stopper function (a function in which the sliding door stops at the fully-open position and does not self-close) that maintains the fully-open state of the sliding door is also necessary.
[0003]
As shown in FIG. 9, the conventional full-open stopper function allows the height of the mounting position to be adjusted in the vertical direction on the angled stopper receiver 2a provided at the top of the sliding door 1a and the fixed side member 3a. The mounting seat 6a and the roller 4a at the tip are rotatable, and the elastic stopper 5a is connected to the mounting seat 6a. When the sliding door 1a is opened to the fully open position, the stopper receiver 2a resists elasticity. The roller 4a of the elastic stopper 5a pushed upward (the state shown in the phantom line in FIG. 9) is located on the door tip side of the top portion 7a and elastically abuts on the fully opened stopper portion 8a, thereby fully opening the sliding door 1a. It was to stop at the position (state shown by the solid line in FIG. 9).
[0004]
However, according to the above configuration, when the sliding door 1a is vigorously opened, the door-end side end of the sliding door 1a collides with the vertical frame on the open side when fully opened, and the stopper receiver 2a moves the elastic stopper 5a upward again by the rebound. The sliding door 1a may be closed by the self-closing function.
In order to prevent this, when the elasticity of the elastic stopper 5a is increased (when the mounting seat 6a is adjusted downward), when the sliding door 1a stopped at the fully open position is closed (from the state shown by the solid line in FIG. 9 to the arrow direction) When the sliding door 1a is moved), it is necessary for the stopper receiver 2a to push the elastic stopper 5a upward against the elasticity, so that there is a problem that the operation force becomes very heavy and difficult to use for the elderly or the sick. It was.
On the other hand, if the elasticity of the elastic stopper 2a is set to be weak (adjusting the mounting seat 6a upward and mounting to the fixed seat member 3a) so that it can be easily used by elderly people or sick people, the sliding door 1a will not rebound. I had to fully open the sliding door 1a with my hand.
[0005]
However, since the fully open position of the sliding door 1a is set to be larger than the passing width of a person, a user of the wheelchair, an elderly person, or a sick person moves the sliding door 1a with his hand to the fully open position. Furthermore, in order to close the sliding door 1a in the fully open position, it is a very troublesome problem to move to a position where the hand can reach the sliding door 1a.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above problems, and has a simple structure, and even if the sliding door is vigorously opened, it does not close by the reaction when fully opened, and the sliding door in the fully opened state (open state) is lightly closed. It is an object of the present invention to provide an innovative sliding door device that can easily maintain a sliding door in an open state even for a wheelchair user, an elderly person, or a sick person.
[0007]
[Means for solving the problems]
Therefore, in order to solve the above-mentioned problem, the first means of the present invention is a sliding door device that can be self- closed along a sliding door rail provided in a space having an opening that can be opened and closed by an inspection cover . When the inspection cover is opened, a stopper receiver provided on the sliding door and an elastic stopper provided on the fixed side are arranged so as to move together with the sliding door at a position where the opening faces , and the elastic stopper is provided with the stopper receiver. A roller is provided at the end of the elastic leg that protrudes toward the door, and the stopper receiver moves the sliding door in response to the contact of the roller when the sliding door is opened at least beyond the passing width of the wheelchair with respect to movement in the opening direction. A braking portion formed to a length that releases the contact state of the roller when the sliding door is fully opened, and the door bottom side of the braking portion And a fully open stopper that maintains the fully open position of the sliding door by projecting at a door tip side end portion of the braking portion at a sharper inclination than the guide portion. The elastic leg of the elastic stopper is configured to elastically abut the roller against the braking portion more strongly than the self-closing force of the sliding door, and the sliding door is at least larger than the passing width of the wheelchair for movement in the opening direction. when moved halfway open it does not reach the fully open position position, while the roller is to be stopped so as not to self-closure of the sliding door by abutting the braking portion via the guide portion, the sliding door by well opening movement of the sliding door momentum When rebounding from the fully open position, the roller over the fully open stopper comes into contact with the braking part and pulls in a state that secures at least the entrance and exit width of the wheelchair. It is the door in that it is configured to stop without autism.
[0008]
The next time the present invention is was configured as a second means, in the sliding door device capable autism along sliding door rails provided in the internal space with a freely opening closed by inspection cover, which is open to the inspection cover An elastic stopper provided on the sliding door and a stopper receiver provided on the fixed side are arranged at a position where the opening faces to move together with the sliding door, and the elastic stopper protrudes toward the stopper receiver. A roller is provided at the end of the body, and the stopper receiver receives the contact of the roller and brakes the movement of the sliding door when the sliding door is opened at least more than the passing width of the wheelchair for movement in the opening direction, but the sliding door is fully opened. The brake part formed to the length that releases the contact state of the roller when it becomes a state, and the guide that inclines and protrudes at the door-end side end part of the brake part And a fully open stopper portion that maintains the fully open position of the sliding door by projecting at a door end side end portion of the braking portion more rapidly than the guide portion, and an elastic leg of the elastic stopper Is configured to elastically abut the roller against the braking portion more than the self-closing force of the sliding door, and with respect to the movement in the opening direction, the sliding door is at least up to the passing position of the wheelchair and not to the fully open position. when it moves, whereas the roller is to be stopped so as not to self-closure of the sliding door by abutting the braking portion via the guide portion, when the sliding door is rebounded from the fully open position by well opening movement of the sliding door momentum, fully open stopper to stop without the self-closure of the sliding door in a state where a roller passing over the part is secured at least wheelchair passage width or more entrance by coming into contact with the braking portion In that it is configured.
[0009]
Next, when the present invention is configured as a third means, the elastic stopper is formed of a leaf spring material, and is formed at an elastic leg protruding in the stopper receiving direction and an end of the elastic leg on the stopper receiving side. The roller mounting seat and a rubber or synthetic resin roller rotatably mounted on the roller mounting seat.

The sliding door 2 self-closing force by the self-closing device, that is, the self-closing force of the sliding door 2 to which traveling force is always applied in the closing direction by the weight body) is more elastically abutting.
[0019]
Since the second embodiment is configured as described above, even when the sliding door 2 is opened with great force, when the roller 54 of the elastic stopper 5 reaches the braking portion 62 of the stopper receiver 6, the roller 54 moves against the braking portion 62. Since the sliding door 2 is elastically abutting more strongly than the self-closing force, the sliding motion of the sliding door 2 is braked, while the sliding motion of the sliding door 2 is also closed, so that the roller 54 is fully opened by the former braking. The sliding door 2 is stopped in a state in which the sliding door 2 is kept in the fully open position by abutting against the opening side of the stopper portion 64 or the door is rebounded by the latter brake and at least an entrance / exit that is larger than the passing width of the wheelchair is secured.
[0020]
That is, the sliding door 2 is in the middle of at least the opening of the above passage width of the wheelchair, by the roller 54 comes into contact with the braking portion 62, is prevented from self-closure, since it stops, wheelchair users or disease have used Pull door It can be performed with a light opening and closing force when performing an operation for stopping 2 in the open state and also when closing the stopped sliding door 2. On the other hand, even if the healthy person vigorously opens the sliding door 2 to stop the sliding door 12 in the open posture, the double door effect of the braking unit 62 ensures that the sliding door 2 is secured in the state in which the doorway 10 is secured. Since it can be stopped, it is not necessary to open the sliding door with your hand until the end. That is, it is possible to flexibly cope with different opening forces of healthy persons or wheelchair users.

【The invention's effect】
According to the first and second aspects of the invention, the sliding door 2 is opened at least more than the width of the wheelchair to reach the fully open position, and the roller 54 of the elastic stopper 5 is passed through the guide portion 63 of the stopper receiver 6. The brake portion 62 is configured to elastically abut, and at that time, the elastic abutment is configured to be stronger than the self-closing force of the sliding door 2, and the door bottom side of the brake portion (62) guide protruding inclined end portion (63) is provided, fully open stopper protruding sharply inclined than the guide portion on the door leading end of the braking portion (62) (63) (64) Is provided. Accordingly, when the sliding door 2 is moved to a position in the middle of opening (at least a position that is not less than the passing width of the wheelchair and does not reach the fully open position), the sliding door 2 is self-closed by the braking action of the roller 54 that contacts the braking portion 62 through the guide portion 63. Therefore, even a wheelchair user, an elderly person, or a sick person can easily maintain the sliding door in an open state , and can be operated with a light opening and closing force. Furthermore, even when a healthy person opens the sliding door 2 vigorously, and the sliding door 2 rebounds from the fully opened position, the braking action of the roller 54 and the braking unit 62 over the fully opened stopper portion 64 is at least larger than the passing width of the wheelchair. Since the self-closing of the sliding door 2 can be prevented and stopped in a state where the doorway is secured, there is an effect that the sliding door 2 is not closed by a recoil when fully opened .
According to the third aspect of the present invention, since a rubber or synthetic resin roller is used at the contact portion between the stopper receiver and the elastic stopper, a collision sound between the stopper receiver and the elastic stopper is generated when the sliding door is opened and closed. It is suitable for places where quietness is required, particularly in hospital rooms.
