Description

【０００１】
【発明の属する技術分野】
本発明は、折戸と引戸を組み合せた折戸式引戸を、折戸部分を転回させながら引戸部分と共にスライドさせて開閉する、身障者や要介護者などにとっても使い勝手のよい折戸式引戸装置に関する。
【０００２】
【従来の技術】
一般に、各種扉の中で、引戸は、車椅子を利用する身障者や要介護者等にとっても、開閉操作が横に引くだけで済む単純で簡単であることから、病院等に多く設置されている。
【０００３】
しかし、引戸には、特に開時、開口部での有効開口幅を最大限に確保しようとすると、開口部の横に、壁などに沿って戸袋部位を設ける必要があり、それだけ余分に設置スペースを確保する必要があり、設置位置も、開口部の横に壁などがある箇所に限定されるという欠点がある。
【０００４】
一方、扉の中には、戸袋部位を必要とせず、開口部での有効開口幅を比較的広く確保できる折戸がある。しかし、折戸には、開閉時に、手で押したり引き込んだりして転回させる動作が必要であり、車椅子を利用する身障者や要介護者等にとっては、開閉操作が引戸のように単純ではなく容易でないという欠点がある。
【０００５】
そこで、従来、開閉操作が単純で簡単な引戸の長所と、有効開口幅を広く確保できる折戸の長所を活かすべく、引戸と折戸の構造を合体させた折戸式引戸装置が提案されている。
【０００６】
この従来の折戸式引戸装置は、取っ手を有する横幅の短い戸先側の引戸パネルに、折り畳み自在な２枚の折戸パネルからなる折戸体を、リンク機構で回動可能に連結して扉を構成し、その扉を壁体の開口部に開閉自在に組み付けている。一方、開口部上方の壁体および下方の床面には、それぞれ内側ガイドレールと外側ガイドレールを２列に並設している。内側および外側ガイドレールは、開閉方向と直交する見込み方向に間隔をあけて平行に固定し、折戸体を上下の内側ガイドレールに連結部を介してスライド自在に係合する一方、引戸パネルを上下の外側ガイドレールに連結部を介してスライド自在に係合して開閉方向に案内する構造にしている。そして、引戸パネルを、取っ手を持って左右にスライドさせると、それに連動して折戸体を転回させながら摺動して開閉するようになっている（例えば、特許文献１参照）。

【０００８】
【発明が解決しようとする課題】
ところが、従来の折戸式引戸装置では、リンク機構で連結した折戸体と引戸パネルを、互いに間隔をあけて２列のガイドレールで開閉方向に案内する構成であるため、構造上、見込み方向に扉全体の厚さが増し、それだけ開口部に扉を設置するスペースを大きく確保する必要があり、しかも、折戸体と引戸パネルとが見込み方向にずれて斜めに連結され、閉止状態では扉の板面が面一でないため、見栄えが悪く美的外観上極めて好ましくないという課題があった。
【０００９】
さらに、開口部下方の床面にも、折戸体と引戸パネルをそれぞれ案内するガイドレールを固設するため、床面に段差を生じ、昨今のバリアフリーの要請に反するという課題があった。
【００１０】
そこで、本発明の目的は、折戸と引戸を組み合せた折戸式引戸装置において、開口部下方の床面に段差を発生させることなく、扉を面一にして設置スペースを必要最小限に抑え、美的外観を向上させることにある。
【００１１】
【課題を解決するための手段】
したがって、請求項１に記載の発明は、たとえば以下に示す図示実施の形態のとおり、壁体Ｗの開口部Ｓ上方に固定した一本のガイドレール１２に、戸車ユニット２５・２５のような走行体を介してスライド自在に係合させて吊持する戸先側の引戸パネル１５と、２枚の折戸パネル１８・１９からなる戸尻側の折戸体２０とを、互いの縦框面が向き合う直列に連結して面一な扉Ａを形成し、その扉Ａの開時は、前記引戸パネル１５が開方向にスライドする開放初期動作に従って前記折戸体２０を折り曲げながら扉Ａを開放する折戸式引戸装置であって、前記折戸体２０は、戸先側折戸パネル１８を前記引戸パネル１５と回動可能に連結する一方、戸尻側折戸パネル１９を、壁体ｗのような支持体に回動可能に連結し、両折戸パネル１８・１９間を、長さ方向に歯溝を形成した横断面円弧形状をなす少なくとも一対の歯部を有するギヤヒンジ３０の歯部３１・３２、３３・３４の噛み合いで、折り畳み自在に連結すると共に、両折戸パネル１８・１９間に折戸始動手段Ｅを付設し、該折戸始動手段Ｅは、前記戸先側折戸パネル１８上の戸尻側端縁には、前記壁体Ｗから離れる片寄位置に押圧ピン３８を立設する一方、前記戸尻側折戸パネル１９上の戸先側端縁には、前記壁体Ｗ側に近接した片寄位置に支軸４２を立設し、その支軸４２で、一端側に突当て部４３ａを設け反対の他端側にテーパ部４３ｂを設けた作動レバー４３を軸支し、該作動レバー４３を、前記扉Ａの閉時は、前記突当て部４３ａが前記壁体Ｗに当接する一方、前記テーパ部４３ｂが前記押圧ピン３８に押し当たる向きに回動付勢してなり、前記扉Ａの開時、前記引戸パネル１５が前記ガイドレール１２の案内で開方向に直進すると、その引戸パネル１５の開放初期動作に応じて、前記突当て部４３ａが前記壁体Ｗに当接状態にある前記作動レバー４３が前記押圧ピン３８に前記テーパ部４３ｂの勾配に沿って押されて回動するように蹴り出され、その作動レバー４３の蹴り出しを契機に両折戸パネル１８・１９を前記壁体Ｗから互いの前記縦框面側が離れる折り込み方向に押動してなることを特徴とする。
【００１２】
【発明の実施の形態】
以下、図面を参照しつつ、本発明の実施の形態について説明する。
【００１３】
図１〜図３に、本発明による折戸式引戸装置の一例を示す。図示折戸式引戸装置は、扉Ａを壁体Ｗに固定するガイドレール体Ｇを介して吊設し、壁体Ｗの開口部Ｓにて開閉方向Ｘに開閉自在に組み付けた構造になっている。
【００１４】
ガイドレール体Ｇは、上側縁部を直角に折り曲げた長尺なベースプレート１０を備え、その正面１０ａの長さ方向両端側に一対のレール取付ブラケット１１・１１をねし止めし、レール取付ブラケット１１・１１の下面にガイドレール１２をネジで固着して懸架している。ガイドレール１２は、下面の長手方向にガイド溝１３を形成して略角パイプ形状に曲げ成形したもので、ガイド溝１３の両側縁に走行路１２ａ・１２ａを形成している。そして、斯かる構成のガイドレール体Ｇを、開口部Ｓ上方で壁体Ｗに固定している。
【００１５】
扉Ａは、横幅が短い開閉方向Ｘ戸先側の引戸パネル１５と、２枚の幅広な折戸パネル１８・１９からなる戸尻側の折戸体２０とを備える。
【００１６】
引戸パネル１５には、図４でも示すように、上下框面間を貫通する一対の取付穴２１・２１が穿設され、それら取付穴２１・２１の若干拡径な各上穴部２１ａに取付パイプ２２・２２を嵌着し、上框面１５ａ上に、取付パイプ２２・２２と各軸挿通穴２３ａの軸心を合わせて一対の戸車取付プレート２３・２３をねじ止めしている。そして、戸車取付プレート２３・２３の各軸挿通穴２３ａを通して取付パイプ２２・２２に、図１〜図３に示すように支持軸２５ａを挿着して一対の戸車ユニット（走行体）２５・２５を上框面１５ａ上に搭載している。
【００１７】
更に、引戸パネル１５には、折戸体２０の戸先側折戸パネル１８と向き合う戸尻側の縦框面に、筒状の樹脂製パネルエッジ２６を嵌め付けてねじ止めしている。パネルエッジ２６は、その嵌付面と反対側の折戸体２０との突当て面２６ａを断面円弧状に形成し、全体に変形な筒状をなす。斯かる構成の引戸パネル１５は、戸車ユニット２５に軸支した戸車２５ａ…をガイドレール１２の走行路１２ａ・１２ａ上に転動自在に係合させてガイドレール体Ｇで吊持する。
【００１８】
一方、折戸体２０は、両折戸パネル１８・１９間を、折戸体２０の長さに合わせて長尺な樹脂製ギヤヒンジ３０で連結している。ギヤヒンジ３０は、例えば図５に示すように、それぞれ長さ方向に歯溝を切って形成した横断面円弧状をなす一対の歯部３１・３２、３３・３４を、２組設けて形成している。歯部３１・３２と歯部３３・３４の間は、噛み合い方向が互いに逆向きになるように、隣接する歯部３２・３３間を、２つの屈曲部分３５ａ・３５ｂをもった折曲板部３５で形成した一体形状になっている。一方、それぞれ折戸パネル１８・１９寄りの歯部３１・３４には、それぞれ折戸パネル１８・１９の角縁に嵌め込んで接着する取付板部分３１ａ・３４ａを形成してなる。そして、ギヤヒンジ３０は、取付板部分３１ａ・３４ａにて折戸パネル１８・１９に嵌め付けて接着する一方、歯部３１・３２、３３・３４の噛み合いで折戸パネル１８・１９を転回可能に連結して折戸体２０を折り畳み自在な構成にしている。
【００１９】
加えて、ギヤヒンジ３０は、歯部３１・３２、３３・３４にそれぞれ有する凹条部に、断面コ形状をなす長尺なアルミニウム製ギヤカバー３６の側縁凸部３６ａを嵌め込んで、該ギヤカバー３６を歯部に被せ、歯部が外側から見えないように覆うと共に、指詰め事故の発生を防止している。なお、図示省略したが、ギヤヒンジ３０は、歯部３１・３２、３３・３４に軸受穴を長さ方向に等間隔に設け、それら軸受穴に駒状のスラスト軸受を嵌め付けてねじ止めしている。そして、スラスト軸受で、折戸パネル１８・１９から加わる荷重を受け止めてヒンジ強度を保持する構造になっている。
【００２０】
さらに、上述した折戸式引戸装置において、折戸体２０には、図１〜図３に示すように、両折戸パネル１８・１９間に折戸始動手段Ｅを付設している。折戸始動手段Ｅは、戸先側折戸パネル１８の上框面１８ａにおいて、戸尻側の端縁に取付プレート３７をねじ止めし、取付プレート３７上に押圧ピン３８を立設している。押圧ピン３８は、上框面１８ａにおいて壁体Ｗから離れる正面側の片寄位置に立てている。
【００２１】
一方、戸尻側折戸パネル１９の上框面１９ａには、戸先側の端縁に取付プレート３９をねじ止めする。取付プレート３９上には、その戸尻側にストッパピン４０とバネ止めピン４１を並べて立設すると共に、戸先寄りに支軸４２を立設し、その支軸４２で作動レバー４３を軸支している。支軸４２は、上框面１９ａにおいて、壁体Ｗに近接した背面側の片寄位置に立てている。作動レバー４３は、全体に略く字状に屈曲させて一端側に突当て部４３ａを設ける一方、他端縁にテーパ部４３ｂを形成し、内部にバネ当て部４３ｃができるように曲げ加工してなる。テーパ部４３ｂは、突当て部４３ａと略平行な向きに他端縁を傾斜させて勾配を付けた形状になっている。そして、支軸４２にねじりコイルばね４４を巻装し、ばね一端をバネ止めピン４１に掛け止め、ばね他端をバネ当て部４３ｃに掛け止めて、作動レバー４３を常時図１中反時計方向に回動付勢し、突当て部４３ａの側縁をストッパピン４０に押し当てる一方、テーパ部４３ｂのテーパ面を押圧ピン３８に押し当ててなる。
【００２２】
さらに、折戸体２０において、戸先側折戸パネル１８は、引戸パネル１５と向き合う戸先側の縦框面に、パネルエッジ４５を嵌め付けてネジ止めしている。パネルエッジ４５は、上記パネルエッジ２６と同様に、嵌付面と反対側の引戸パネル１５との突当て面４５ａを断面円弧状に形成して全体に変形な筒状をなし、中空部の上下に軸保持部４５ｂ・４５ｂを設けてなる。そして、上下の軸保持部４５ｂ内に、図４に示すようにそれぞれ回動支軸４６・４６を挿着し、回動支軸４６・４６の突端を、連結プレート４７の一端に有する連結穴４７ａに嵌合する一方、その他端側で連結プレート４７をパネルエッジ２６にねじ止めしている。これによって、両パネルエッジ２６・４５の突当て面２６ａ・４５ａを隙間なく突き合わせた状態で、引戸パネル１５に対し折戸体２０の戸先側折戸パネル１８を、回動支軸４６・４６を支点として回動可能に連結している。
【００２３】
他方、折戸体２０の戸尻側折戸パネル１９には、図１〜図３に示すように、上框面１９ａと下框面における戸尻側に、それぞれガイドヒンジ４９とサポートヒンジ５０を組み付けている。上方のガイドヒンジ４９は、上框面１９ａに軸挿着部５１ａを埋設状態で固定した枢着具５１を備え、軸挿着部５１ａ内に弾着したピボット軸５３の突端を、アングルプレート５２の嵌合穴５２ａに係合させて、枢着具５１に対しアングルプレート５２を回動可能に連結する。下方のサポートヒンジ５０は、下框面に軸嵌着部５４ａを埋設して固定した枢着具５４に、支持プレート５５を、その支持プレート上に立設の枢軸５６と軸嵌着部５４ａとの嵌め合いで回動可能に連結する。そして、支持プレート５５は床面Ｆ側にねじ止めし、アングルプレート５２はガイドレール体Ｇにねじ止めし、折戸体２０の戸尻側折戸パネル１９を、上下のピボット軸５３および枢軸５６を支点として回動可能に支持している。
【００２４】
こうして図１および図２に示すように、扉閉止時は、折戸体２０と引戸パネル１５とを互いの縦框面が正対する直列に連結し、扉Ａを全体に面一に構成している。このように扉Ａが閉止状態のとき、折戸始動手段Ｅにおいて作動レバー４０は、突当て部４３ａがガイドレール体Ｇの正面１０ａに当接した状態にある。
【００２５】
さて、上述した構成の折戸式引戸装置において、いま閉止状態にある扉Ａを開くときは、不図示の取っ手を持って、引戸パネル１５を戸尻側へスライドさせる。そのとき、ガイドレール１２の走行路１２ａ・１２ａ上を戸車２５ａ…が転動し、引戸パネル１５がガイドレール１２の案内で直進すると、この引戸パネル１５の開放初期動作に応じて、折戸体２０の戸先側折戸パネル１８が押動し、それに従って折戸始動手段Ｅの押圧ピン３８が作動レバー４３を、テーパ部４３ｂの勾配に沿って押圧する。テーパ部４３ｂにて押圧されると、作動レバー４３は、突当て部４３ａがガイドレール体Ｇの正面１０ａに当接した状態にあるため、図６に示すように図中時計方向へ回動するように蹴り出される。すると、この作動レバー４３の蹴り出しを契機に、戸尻側折戸パネル１９が連動して戸先部側が壁体Ｗから離れる折り込み方向へと、ピボット軸５３および枢軸５６を支点として回動し始める。
【００２６】
このように戸尻側折戸パネル１９が回動し始めると、両折戸パネル１８・１９間の間隔が狭まるが、その動きに従って、図７に示すように、ギヤヒンジ３０が歯部３１・３２、３３・３４の噛み合いを介して追従し、折曲板部３５の屈曲部分３５ａ・３５ｂが屈曲しながら揺動する。すると、このギヤヒンジ３０の動きに連動して戸先側折戸パネル１８も、戸尻部側が壁体Ｗから離れる折り込み方向へと、回動支軸４６・４６を支点として回動し始める。
【００２７】
そして、更に引戸パネル１５を開方向へスライドさせて、折戸始動手段Ｅの押圧ピン３８で作動レバー４３をテーパ部４３ｂにて押圧すると、それに従い両折戸パネル１８・１９が共に折り込み方向へ転回する一方、図８に示すように、ギヤヒンジ３０が歯部３１・３２、３３・３４の噛み合いを介して追従し、折曲板部３５の屈曲部分３５ａ・３５ｂが屈曲しながら揺動し、図９に示すように、次第に折戸体２０がくの字に折れ曲がる。更に、引続き引戸パネル１５を開方向へスライドさせると、折戸体２０は両折戸パネル１８・１９を転回しながら、更に鋭角な折れ曲がり状態になって扉Ａを次第に戸先側を開放状態にする。その後、更に折り込み方向に両折戸パネル１８・１９を転回させと、折戸体２０が図１０〜図１２に示すように折り畳み状態になり、開口部Ｓが全開する。
【００２８】
さて反対に、扉Ａを閉めるときは、同様に取っ手を持って、引戸パネル１５を戸先側へ向かう閉方向へ引く。すると、折戸体２０が開時とは反対向きに両折戸パネル１８・１９を転回させながら、引戸パネル１５と共に閉方向へスライドする。その後、引戸パネル１５の戸先側縦框面が戸当たりに当接したとき、図１および図２に示すように扉Ａで開口部Ｓが閉止される。
【００２９】
【発明の効果】
請求項１に記載の発明によれば、引戸と折戸の構造を合体させた構成にすることによって、開閉操作が単純で簡単な引戸の長所と、開口部における有効開口幅を広く確保する折戸の長所を活かすことができると同時に、従来のように構造上見込み方向に扉の厚さが増すために開口部に扉設置スペースを大きく確保する必要性をなくし、折戸体と引戸パネルとが見込み方向にずれて斜めに連結される弊害も解消し、これによって、扉設置スペースを必要最小限に抑える共に、たとえ引戸と折戸の合体扉であっても、見栄えを悪化させることなく、美観性を高める効果を奏することができる。
【００３０】
しかも、開口部下方の床面に、従来のように折戸体と引戸パネルを案内するガイドレールを設けて床面に段差が発生する弊害を解消することができ、昨今のバリアフリーの要請にも十分に適応することができる。
【００３１】
加えて、両折戸パネル間を少なくとも一対の歯部を有するギヤヒンジの歯部の噛み合いで折り畳み自在に連結すると共に、折戸体の折れ曲がり箇所である両折戸パネル間に折戸始動手段を備える構成であるため、引戸パネルをスライドさせて扉を開閉するとき、折戸体が、より抵抗少なくスムーズに折れ曲がり、車椅子を利用する身障者や要介護者等によっても、扉の開閉操作を負荷なく著しく容易に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a folding door type sliding door device that is easy to use for a handicapped person or a care recipient who opens and closes a folding door type sliding door combining a folding door and a sliding door with the sliding door part while turning the folding door part.
[0002]
[Prior art]
In general, among various doors, sliding doors are often installed in hospitals and the like because it is simple and easy for the handicapped person who needs a wheelchair or a care recipient to simply open and close the door.
[0003]
However, especially when opening the sliding door, when trying to secure the maximum effective opening width at the opening, it is necessary to provide a door pocket part along the wall etc. on the side of the opening. There is a disadvantage that the installation position is limited to a place where there is a wall or the like next to the opening.
[0004]
On the other hand, there is a folding door that does not require a door pocket part and can ensure a relatively wide effective opening width in the opening. However, folding doors must be turned by pushing or pulling in by hand during opening and closing, and opening and closing operations are not as simple and easy as those for sliding doors for disabled people or care recipients who use wheelchairs. There is a drawback.
[0005]
Therefore, conventionally, a folding door type sliding door device that combines the structure of the sliding door and the folding door has been proposed in order to take advantage of the advantage of the sliding door that is simple and easy to open and close and the advantage of the folding door that can ensure a wide effective opening width.
[0006]
This conventional folding door type sliding door device is configured by connecting a folding door body composed of two folding door panels that are foldable to a sliding door panel on the side of a door with a short width and having a handle so as to be rotatable by a link mechanism. The door is assembled to the opening of the wall so as to be freely opened and closed. On the other hand, an inner guide rail and an outer guide rail are arranged in two rows on the wall body above the opening and the floor surface below. The inner and outer guide rails are fixed parallel to each other in a prospective direction perpendicular to the opening and closing direction, and the folding door body is slidably engaged with the upper and lower inner guide rails via the connecting portion, while the sliding door panel is vertically moved. The outer guide rail is slidably engaged via a connecting portion and guided in the opening / closing direction. When the sliding door panel is slid left and right with a handle, the sliding door is slid and opened and closed in conjunction with the sliding door panel (see, for example, Patent Document 1).
[0007]
[Patent Document 1]
JP 2002-13352 A (pages 6 to 8, FIGS. 1 to 4)
[0008]
[Problems to be solved by the invention]
However, in the conventional folding door type sliding door device, the folding door body and the sliding door panel connected by the link mechanism are configured to be guided in the opening / closing direction by two rows of guide rails with a space between each other. The overall thickness increases, and it is necessary to secure a large space for installing the door in the opening.Further, the folding door body and the sliding door panel are displaced obliquely in the expected direction, and in the closed state the door plate surface However, there is a problem that the appearance is poor and the appearance is extremely unfavorable.
[0009]
Further, since guide rails for guiding the folding door body and the sliding door panel are fixedly provided on the floor surface below the opening, there is a problem that a step is generated on the floor surface, which is contrary to the recent demand for barrier-free.
[0010]
Accordingly, an object of the present invention is to provide a folding door type sliding door device in which a folding door and a sliding door are combined, without causing a step on the floor surface below the opening, keeping the door flush and minimizing the installation space. It is to improve the appearance.
