Description

【０００１】
【発明の属する技術分野】
本発明は、建物などに付設される扉に設けられ、この扉の開閉を行う操作部分を改良した扉の構造に関するものである。
【０００２】
【従来の技術】
建物の開口部などに設けられる扉には、その開閉を行うためにノブやレバーハンドルが設けられる。これらノブやハンドルは、扉における戸先側の両面に配設され、この戸先側に内蔵される錠機構部を構成するラッチボルトの木口に対する進退を行う。
【０００３】
ノブの場合、これを掴み持ち、回転させることでラッチボルトを木口より後退させ建物枠側のストライクから退かせ係合状態を解き、そして、ノブを掴み持った状態で扉に対して押す、或いは引く、という操作にて扉の開放を行う。
また、ハンドルの場合では、ハンドルを掴み持ち、扉面に対し、この扉面と平行な方向に所定角度揺動させることで、すなわち扉面に植設状態の軸部の回転にて、ラッチボルトの後退が行われ、そして、ハンドルを掴み持った状態で扉を押す、或いは引くことで扉の開放が行われる。
【０００４】
そして、これらノブやハンドルに対する人の操作において、扉を押して開く場合に、ノブの場合は、掴み持ち回転させたノブ自体を押す方向に操作することで行い、また、ハンドルの場合も、掴み持ち揺動させたハンドル自体を押す方向に操作することで行う。
【０００５】
ところが、これらノブやハンドルの場合に、扉を開放する「押す」という操作を行う直前に、「回転」或いは「揺動」という操作が必要なことから、障害者や高齢者など手が不自由である場合に、扉の開放操作を行いにくいことがある。
【０００６】
このような不具合に対し、扉の開放方向と同方向に操作を行うことでラッチボルトを後退させる機構となるハンドル構造、所謂プッシュプル錠が下記特許文献１等にある。
このプッシュプル錠は、扉を開放する「押す」「引く」という操作方向と同方向に揺動するレバーで構成され、押すことで開放する扉の一方の面には扉面に対して近接する方向に揺動するレバーが設けられ、また、引くことで開放する扉の他方の面には扉面に対して離間する方向に揺動するレバーが設けられており、これらレバーの揺動、すなわち、「押す」或いは「引く」という操作にてラッチボルトが後退し、扉の開放が行える構造となっている。
【０００７】

【０００８】
【発明が解決しようとする課題】
しかしながら、上述した従来のプッシュプル錠を備えた扉では、扉の開閉動作が急激に行われないように制御するドアクローザーが設けられていない場合や、室内扉など扉自体が軽量に構成されている場合に、その扉の開放操作を行う際に、特に扉を押して開放する側では、開放操作を行う者が、扉とともに開放方向に勢いがつき、操作方向である前方に倒れ込んでしまったり、また、扉を勢いよく開けてしまうことで扉の向こう側にいる人に扉を衝突させてしまうことがあり、非常に危険であるという問題があった。
【０００９】
そこで本発明は、上記問題点を解消するために、扉の開放操作方法、特に扉の押して開ける側での操作構造を改善し、開放する扉による事故を未然に防ぐことを可能とする扉の構造を提供することを目的としている。
【００１０】
【課題を解決するための手段】
次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。
この発明の請求項１記載の扉の構造は、進退自在な係合杆５による係合にて閉鎖状態を維持され、押す方向が開放方向となる扉１であって、該扉１の押される面１ｄに配設され、扉１の開放方向と略同方向に揺動自在となる把手１０を備え、該把手１０を前記扉１の開放方向と同方向に揺動させることで、前記係合杆５による係合状態を解除し扉１の開放が行われる扉の構造において、
前記把手１０の前記扉面１ｄに対向する裏面に配設され、基端２２ａが前記把手１０の揺動端近傍に位置し、該把手１０の裏面に近接する厚み方向に移動自在な操作片２２と、
該操作片２２の先端２２ｂ側に設けられ、前記扉面１ｄに向かって突設される係合片２３と、
前記把手１０の揺動基端に枢軸を介して揺動自在に設けられ、前記係合杆５を備える錠機構部４内に延出し、該錠機構部４に開放操作の出力を行う作動片２５と、
該作動片２５と一体に設けられ前記把手１０の裏面に向かって延出し該作動片２５とともに揺動自在とされ、前記係合片２３に対し係脱自在とされるとともに、前記把手１０の当接部１４ｄに対して係脱自在とされる連動片２７と、
を具備し、
前記把手１０を前記扉１の開放方向に押圧し揺動させることで、前記当接部１４ｄが前記連動片２７と係合し、該連動片２７を揺動させるとともに前記作動片２５を揺動させて、該作動片２５にて前記把手１０の揺動操作を前記錠機構部４に伝達し、
前記把手１０とともに前記操作片２２を掴み持つことで、前記係合片２３が前記連動片２７と係合し、前記把手１０の揺動操作とともに前記作動片２５が揺動して前記錠機構部４に伝達し、前記扉１の開放が行われることを特徴とする。
【００１１】
このような扉の構造によれば、押すことで開放する扉１に対する開放操作において、押すことで揺動し係合杆５を後退させる把手１０に、操作片２２を設け、この操作片２２とともに把手１０を握持することで操作し、錠機構部４内に直接操作力が伝わる作動片２５を把手１０と略一体となるように係合片２３と連動片２７とを係合状態として、扉の開放操作を行えるように構成したので、扉１に対する「押す」という開放操作に、操作片２２を掴み持つ前段操作を必要とすることから、開放方向への扉１の急激な開放が抑止され、扉１の向こう側にいる人に扉１を衝突させるような事故等、扉１を勢いよく開放してしまうことで発生する事故を未然に防ぐことが可能となる。
【００１２】
また、操作片２２を掴むことなく、把手１０を押圧させるのみの開放操作となっても、この把手１０の揺動を、さらに押し込むように押圧操作することで、すなわち、把手１０を２段階で押圧するような操作を行うことによって、作動片２５が把手１０と略一体となるように当接部１４ｄと係合片２３とを係合状態とされる構成としたので、扉１に対する「押す」という開放操作を、単純に押圧するのみでなく、さらに押し込むような操作を必要とすることから、開放方向への扉１の急激な開放操作を行っても、扉１はすぐには開放されずに抑止され、上記同様に扉１の向こう側にいる人に扉１を衝突させるような事故等、扉１を勢いよく開放してしまうことで発生する事故を未然に防ぐことが可能となる。
【００１３】
請求項２記載の扉の構造によれば、前記把手１０は、略板状に形成され、前記扉面１ｄに対向する裏面に、該裏面に直交して突出形成する腕部１４を備え、該腕部１４先端を前記揺動基端とされて前記扉面１ｄ側に枢着され、該腕部１４内に長手方向に形成される管状の中空部１４ｂ内に前記係合片２３と連動片２７及び当接部１４ｄが配置されることを特徴とする。
【００１４】
このような扉の構造によれば、把手１０の腕部１４内に係合片２３と連動片２７及び当接部１４ｄとが外部に表出することなく、機構部分を隠すことととなり、見栄えを低下させることがない。
【００１５】
請求項３記載の扉の構造によれば、前記枢軸は、前記把手１０の揺動中心軸１８を兼ねることを特徴とする。
【００１６】
このような扉の構造によれば、把手１０の揺動中心と作動片２５の揺動中心とを１つの部材で構成でき、簡素な構造で得ることが可能となる。
【００１７】
請求項４記載の扉の構造によれば、前記操作片２２には、前記把手１０の裏面から離脱する方向に付勢する付勢部材２４が備えられることを特徴とする。
【００１８】
このような扉の構造によれば、操作片２２は、把手１０の裏面において常に離脱方向に付勢されており、係合片２３の移動が行われず、連動片２７を介する作動片２５の揺動を行わない状態、すなわち係合片２３と連動片２７との係合状態とならない状態を保ち、把手１０を勢いよく押すことでの扉１の開放操作を、上記したように押圧操作を単なる押圧操作ではなく、さらに押し込むような操作を必要な状態に維持することとなり、急な押し開け操作で簡単に扉１が開放しない状態を保つこととなる。
【００１９】
【発明の実施の形態】
図１に示すように、扉１は、吊元１ａとなる一側縁に、蝶番３などを介して建物開口部２の一方の縁部２ａ等に連結される。そして建物開口２に対して吊元１ａの蝶番３を中心として建物開口部２の一方側、例えば屋外側や廊下側などの隔てられた空間のいずれか側の方向に揺動し、開閉する。扉１の戸先１ｂには、錠機構部４が内蔵される。錠機構部４は、係合杆としてのラッチボルト５を具備し、後述するレバーハンドル１０が連結されている。ラッチボルト５は、戸先１ｂの木口１ｃに対して進退自在に設けられ、扉１が建物開口部２を閉鎖している際に、木口１ｃから突出した状態で、建物開口部２の他方の縁部２ｂに設けられるストライク板の係合穴６に嵌入する。そして、ラッチボルト５が係合穴６に嵌入し係合した状態では、扉１は閉鎖状態を保たれる。
なお、このラッチボルト５は、例えば閂状のラッチとして構成してもよく、可倒ラッチなどで構成されてもよい。
【００２０】
扉１の戸先１ｂ側の表裏両面には、把手としてのレバーハンドル１０が配設される。なお、以下に説明する本実施の形態では、扉１の一方の面１ｄである押して開放する側のレバーハンドル１０について説明し、引いて開放させる側である他方の面に配設されるレバーハンドルについては図示を省略しその詳述を行わない。
【００２１】
図１に示すように、扉１の一方の面１ｄ、すなわち、押すことで開放方向へと揺動させる操作の行われる扉の押される面１ｄにおける戸先１ｂ側には、レバーハンドル１０が配設される。
【００２２】
レバーハンドル１０は、図２に示すように、押圧部１１と腕部１４とが略直交した略Ｌ字状に形成される。
押圧部１１は、本実施の形態では、扉面１ｄと略平行となる矩形板状に形成される。押圧部１１には、扉面１ｄに対向する裏面に凹部１２が形成される。この凹部１２は、略矩形状に形成され、押圧部１１の裏面において周囲の端縁部分を突条形状とするように形成されており、レバーハンドル１０としての重量軽減を兼ねるとともに、後述する操作片２２の作動領域となる。また、この押圧部１１の先端縁部は、レバーハンドル１０としての揺動端となり、握持部１３とされる。
【００２３】
腕部１４は、押圧部１１の裏面における握持部１３と反対の側縁近傍に位置し、この裏面に直交して突出形成されるように、押圧部１１と一体に設けられる。本実施の形態の腕部１４は、略円柱状に形成される。腕部１４の先端１４ａは、レバーハンドル１０としての揺動基端となり、軸支部１５を構成している。この軸支部１５は、腕部１４と一体に構成される連結部１６と、扉面１ｄ側に固定されるベース部１７とで構成され、略垂直方向を軸線方向とした揺動軸１８を介して互いが連結され、この軸支部１５によりレバーハンドル１０が揺動自在となっている。なお、この軸支部１５の連結部１６と腕部１４とは、ネジやボルトなどの固定手段２０にて固定され、また、ベース部１７は、扉１および戸先１ｂに内蔵される錠機構部４に対して、図に示す取付杆１９や、ネジ，ボルトなどにて固定される。
【００２４】
本実施の形態では、軸支部１５に対して延出する腕部１４及び押圧部１１が、図１に示すように、通常の状態において、押圧部１１の板面が扉面１ｄと略平行となり、この押圧部１１が腕部１４から吊元１ａに向いて延出している。
【００２５】
また、腕部１４には、長手方向である軸線方向に沿う略管状の中空部１４ｂが形成されている。本実施の形態では、図２に示すように、腕部１４の先端１４ａ側に略円筒形状に形成され連結部１６と一体となる支持筒２１が挿着され、軸線方向に貫通した穴部とともに中空部１４ｂを構成している。中空部１４ｂの一端は、図３に示すように、連結部１６を貫通し腕部１４の先端略中央にスリット状に開口している。
【００２６】
さらに、この腕部１４は、握持部１３側の側部に、略溝状の開口部１４ｃを有している。この開口部１４ｃは、凹部１２及び中空部１４ｂと連通しており、後述する操作片２２の先端２２ｂ側及び連動片２７の一側が配置されるようになっている。また、この腕部１４の開口部１４ｃに対する奥方位置となる中空部１４ｂ内面は、後述する連動片２７が係合する当接部１４ｄとなっている。
【００２７】
なお、図示しないが、揺動軸１４ｂには、捩じりコイルバネなどの付勢部材が巻装され、この捩じりコイルバネの付勢力により、通常の状態で扉面１ｄに対して腕部１４が略直交となる状態を維持する構成としても良い。
【００２８】
次に、操作片２２は、レバーハンドル１０の押圧部１１裏面に配設される。この操作片２２は、図２，図３に示すように、上述した押圧部１１裏面の凹部１２の内寸法に対応した略矩形板状の部材とされ、この凹部１２に対し、押圧部１１の厚み方向に進退自在とされる。本実施の形態では、押圧部１１の凹部１２内にて揺動することで厚み方向に進退するようになっており、揺動中心を基端２２ａとし、押圧部１１の揺動端における凹部１２内とされ、先端２２ｂが腕部１４に近接し、先端２２ｂが揺動端となっている。なお、操作片２２の基端２２ａは、押圧部１１に対して、軸部などを設け、例えば基端２２ａにおける両端縁と押圧部１１の凹部１２内における握持部１３側の両内側とを軸と軸受で構成して連結し、押圧部１１に対して操作片２２を揺動自在とする構成としても良い。
【００２９】
また、この操作片２２の腕部１４に近接した先端側には、係合片２３が突設されている。この係合片２３は、図２に示すように、先端２３ａが図中上向きに湾曲し略Ｊ字形のフック状に形成され、腕部１４の側部に形成された開口部１４ｃより中空部１４ｂ内に挿入状態で延設される。
【００３０】
操作片２２の押圧部１１側となる一方の面には、支持凹部２２ｃが設けられており、これに対向して凹部１２内に形成される取付凹部１１ａとの間に、付勢部材としての圧縮コイルバネ２４が介装され、操作片２２をレバーハンドル１０裏面から離脱する方向となるように常に付勢している。
【００３１】
次に、作動片２５は、レバーハンドル１０の揺動基端である腕部１４の先端１４ａに設けられる。この作動片２５は、本実施の形態では、図２に示すように、略短冊板状に形成されており、腕部先端１４ａの連結部１６とベース部１７とを貫通し連結する揺動軸１８が基部２５ａを貫通し、揺動自在とされて取り付けられる。なお、この揺動軸１８は、作動片２５の枢軸を兼ねている。
【００３２】
作動片２５は、先端２５ｂが腕部１４の軸線方向に略沿って延出しており、その先端２５ｂが戸先１ｂに内蔵される錠機構部４内に位置するようになっている。この作動片２５は、錠機構部４内にて、ラッチボルト５の進退動作を行う機構に係合するようになっている。なお、図２には、その機構の一部である連動部２６を示している。
【００３３】
次に、連動片２７は、作動片２５と一体に設けられ、すなわち、作動片２５の基部２５ａを中途部分とした長尺体とされて、基部２５ａより一方の略半部を作動片２５とされ他方の略半部を連動片２７として構成されている。そして、中途部分の基部２５ａを貫通した揺動軸１８により腕部１４の中空部１４ｂ内で揺動自在とされている。この連動片２７は、本実施の形態では、図２に示すように、先端２７ａが図中下向きに湾曲し略逆Ｊ字形のフック状に形成されている。この先端２７ａは、図２に示すように、操作片２２の係合片先端２３ａと対向する。そして、この連動片２７は、腕部１４の中空部１４ｂ内で、先端２７ａが係合片２３の先端２３ａと当接部１４ｄとの間を揺動自在とされる。また、この連動片２７の一側には、閉塞部２７ｂが突出形成されている。この閉塞部２７ｂは、腕部１４の開口部１４ｃに位置する。
【００３４】
なお、係合片２３の先端２３ａと連動片２７の先端２７ａとは、図２に示すように、通常の状態で互いに係合することなく向き合い、連動片２７の閉塞部２７ｂの上縁とで形成される空間に係合片２３の先端２３ａが位置している。
【００３５】
次に、上記のように構成された扉の構造の操作について説明する。
扉１が建物開口２を閉塞した状態では、図１に示すように、錠機構部４のラッチボルト５先端が突出しており、係合穴６に進入し、扉１の閉塞状態が保たれる。
【００３６】
また、この閉塞状態においては、図２に示すように、押圧部１１の握持部１３裏面に位置している操作片２２が、圧縮コイルバネ２４の付勢力により、押圧部１１裏面の凹部１２より突出しており、この操作片２２と略一体構造とされる係合片２３と、連動片２７とは互いに係合することなく対向した状態とされる。なお、この状態では、作動片２５の先端２５ｂは、錠機構部４の連動部２６に接触している状態となっている。
【００３７】
なお、本発明の扉の構造では、レバーハンドル１０を掴み持って押圧し扉１を開放させる方法と、レバーハンドル１０の押圧部１１を押圧するのみで扉１を開放させる方法との２種類の操作方法がある。
【００３８】
まず、レバーハンドル１０を掴み持ち、扉１を開放する操作手順を説明する。この扉１を開放するには、まず、レバーハンドル１０の握持部１３側を、開放しようとする操作者が握持する。握持部１３側を掴むことで、この握持部１３の裏面に位置する操作片２２は、押圧部１１に対する押圧方向とは反対の引く方向の操作となり、圧縮コイルバネ２４の付勢力に抗して押圧部１１裏面の凹部１２内に進入する。このとき、掴む際の指先側が操作片２２の揺動端（先端２２ｂ）側であることから容易に操作片２２は揺動されることとなる。
【００３９】
図４に示すように、操作片２２の凹部１２内への進入とともに、係合片２３が連動片２７と互いに係合状態となる。
【００４０】
次に、操作者は、レバーハンドル１０の押圧部１１を押圧して軸支部１５を中心に揺動させる。この揺動操作の際、操作片２２の係合片２３が連動片２７と係合状態であることから、この連動片２７は揺動軸１８を中心に揺動することとなり、すなわち、レバーハンドル１０，操作片２２，係合片２３，連動片２７，作動片２５が略一体となって、この作動片２５が揺動軸１８に対して揺動して、レバーハンドル１０の揺動とともに錠機構部４内を揺動されることとなる。これにより図５に示すように作動片２５は所定角度（図５中α）揺動して連動部２６を押圧し、この連動部２６に連動連結されるラッチボルト５が後退となる。すなわち、扉１はラッチボルト５による係止維持状態を解かれる。
【００４１】
係止状態を解かれた扉１は、レバーハンドル１０を掴み持ち、レバーハンドル１０に対して押圧力を加えている操作者の開放操作、すなわち押圧している操作により、開放方向へと吊元１ａの蝶番３を中心として揺動する。
そして、そのまま扉１を開放方向に押すことにより、扉１が開放となる。
【００４２】
次に、この扉１を開放させる際に、レバーハンドル１０の握持部１３を掴み持つことなく開放操作を行う操作手順について説明する。
まず、扉１を開放させようとする操作者は、レバーハンドル１０の押圧部１１を正面から押圧する。
【００４３】
レバーハンドル１０は、その押圧操作によって、軸支部１５を中心に揺動する。操作片２２は、操作者により握持されないことから移動せず、係合片２３と連動片２７とが係合しない状態のままである。すなわち、このレバーハンドル１０の揺動の際に、連動片２７及び作動片２５に対して揺動自在な状態となっている。このレバーハンドル１０の揺動によって、係合片２３は連動片２７との対向位置から離脱し移動することとなる。すなわち、連動片２７は揺動せず、腕部１４の中空部１４ｂにより、連動片２７に対して腕部１４が揺動することとなる。
【００４４】
レバーハンドル１０が揺動し、所定角度（図６中β）まで揺動すると、中空部１４ｂ内にて、連動片２７の先端２７ａは当接部１４ｄと係合状態となる。
【００４５】
そして、さらに、レバーハンドル１０を押圧して揺動させると、図７に示すように、当接部１４ｄに係合した連動片２７がレバーハンドル１０の揺動とともに揺動する。これにより作動片２５が所定角度（図７中γ）揺動して、錠機構部４の連動部２６を押圧し、この連動部２６に連動連結されるラッチボルト５が後退となる。すなわち、レバーハンドル１０を通常の操作よりも大きく揺動操作（図７中矢線Ｐ）させることで、扉１はラッチボルト５による係止維持状態を解かれる。
【００４６】
係止状態を解かれた扉１は、レバーハンドル１０に対して押圧力を加えている操作者の開放操作、すなわち押圧している操作により、開放方向へと吊元１ａの蝶番３を中心として揺動する。
そして、そのまま扉１を開放方向に押すことにより、扉１が開放となる。
【００４７】
従って、このように構成された扉の構造によれば、押すことで開放する扉１に対する開放操作において、押すことで揺動しラッチボルト５を後退させるレバーハンドル１０に、操作片２２を設け、この操作片２２をレバーハンドル１０の握持部１３を握持することで操作し、錠機構部４内の連動部２６に直接操作力が伝わる作動片２５をレバーハンドル１０と略一体となるように係合片２３と連動片２７とを互いに係合させた状態として、扉の開放操作を行えるように構成したので、扉１に対する「押す」という開放操作に、操作片２２を掴み持つ前段操作を必要とすることから、開放方向への扉１の急激な開放が抑止され、扉１の向こう側にいる人に扉１を衝突させるような事故等、扉１を勢いよく開放してしまうことで発生する事故を未然に防ぐことが可能となる。
特に、操作片２２の揺動基端を、握持部１３側に配置したことで、レバーハンドル１０を掴む際の指先側が揺動端（２２ｂ）となり、手指の動きに対応していることから、操作片２２を揺動させるという意識を抑えることが可能となる。
【００４８】
また、操作片２２を掴むことなく、レバーハンドル１０を押圧させるのみの開放操作となっても、このレバーハンドル１０の揺動を、さらに押し込むように押圧操作することで、すなわち、レバーハンドル１０を２段階で押圧するような操作を行うことによって、作動片２５がレバーハンドル１０と略一体となるように規制状態とされる構成としたので、扉１に対する「押す」という開放操作を、単純に押圧するのみでなく、さらに押し込むような操作を必要とすることから、開放方向への扉１の急激な開放操作を行っても、扉１はすぐには開放されずに抑止され、上記同様に扉１の向こう側にいる人に扉１を衝突させるような事故等、扉１を勢いよく開放してしまうことで発生する事故を未然に防ぐことが可能となる。また、このさらに押し込むような操作を行うことで扉を開放できる構成であることから、例えば、操作片２２を掴み持つことができない場合や、掴み持つことが行えない場合、すなわち握力のない人や荷物を両手に持った状態の人などに対応でき、このような人たちの開放操作においても従来のような扉が急激に開放してしまうなどの不具合を解消することができて、なおかつ扉１の開放操作が行えることとなる。
【００４９】
なお、上述した実施の形態では、レバーハンドル１０における押圧される部分である押圧部１１を略矩形板状とした例について説明したが、レバーハンドル１０としての形状については、これに限定されるものではなく、円形や楕円形、多角形など、その他の形状としてもよく、また、板状ではなく、例えば枠状に形成されることとしても良く、揺動先端側を握持部１３とする形状であれば上記形状に限定されるものではない。
また、レバーハンドル１０を構成する腕部１４の形状についても、上記実施の形態における形状に限定されるものではない。
【００５０】
さらに、上述した実施の形態では、レバーハンドル１０の揺動先端である握持部１３の軸支部１５に対する向きが、扉１の戸先１ｂから吊元１ａに向くよう構成した例について説明したが、このレバーハンドル１０の扉１への取り付け状態については、軸支部１７に対する握持部１３の延出方向が吊元１ａから戸先１ｂ側として構成されてもよく、また、その他の方向とされて構成されていても、上記同様の作用効果を得ることができる。
【００５１】
【発明の効果】
以上説明したように本発明による扉の構造では、押すことで開放する扉に対する開放操作において、押すことで揺動し係合杆を後退させる把手に、操作片を設け、この操作片を把手とともに握持することで操作し、錠機構部内に直接操作力を伝える作動片を把手と略一体となるように係合片の連結片とを係合状態として、扉の開放操作を行えるように構成したので、扉に対する「押す」という開放操作に、操作片を掴み持つ前段操作を必要とすることから、開放方向への扉の急激な開放が抑止され、扉の向こう側にいる人に扉を衝突させるような事故等、扉を勢いよく開放してしまうことで発生する事故を未然に防ぐことが可能となる。
【００５２】
特に、操作片の基端を、把手の揺動端側に配置したことで、把手を掴む際の指先側が操作片の移動端側となり、手指の動きに対応していることから、操作片を移動させるという意識を抑えることが可能となる。
【００５３】
また、操作片を掴むことなく、把手を押圧させるのみの開放操作となっても、この把手の揺動を、さらに押し込むように押圧操作することで、すなわち、把手を２段階で押圧するような操作を行うことによって、作動片が把手と略一体となるように当接部と連動片とが係合状態とされる構成としたので、扉に対する「押す」という開放操作を、単純に押圧するのみでなく、さらに押し込むような操作を必要とすることから、上記同様に開放方向への扉の急激な開放が抑止され、扉の向こう側にいる人に扉を衝突させるような事故等、扉を勢いよく開放してしまうことで発生する事故を未然に防ぐことが可能となる。
【００５４】
さらに、このさらに押し込むような操作を行うことで扉を開放できる構成であることから、例えば、操作片を掴み持つことができない場合や、掴み持つことが行えない場合などに対応でき、従来のような扉が急激に開放してしまうなどの不具合を解消することが可能であって、扉の開放が行えることとなる。

[Problems to be solved by the invention]
However, the door with the conventional push-pull lock described above does not include a door closer that controls the opening and closing operation of the door not to be performed suddenly, or the door itself such as an indoor door is configured to be lightweight. When performing the opening operation of the door, especially when the door is opened by pushing the door, the person performing the opening operation, with the door, gains momentum in the opening direction and falls down forward in the operation direction, In addition, there is a problem that opening the door with force may cause a person on the other side of the door to collide with the door, which is extremely dangerous.
[0009]
In order to solve the above-described problems, the present invention has improved a door opening operation method, particularly an operation structure on the side where the door is pushed and opened, and a door which can prevent an accident due to the opening door. It is intended to provide structure.
[0010]
[Means for Solving the Problems]
Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The door structure according to the first aspect of the present invention is a door 1 in which the closed state is maintained by the engagement of the reciprocally movable engagement rod 5 and the pushing direction is the opening direction, and the door 1 is pushed. A handle 10 is provided on the surface 1d and is swingable substantially in the same direction as the opening direction of the door 1. The handle 10 is swung in the same direction as the opening direction of the door 1 so that the engagement is achieved. In the door structure in which the engagement state by the rod 5 is released and the door 1 is opened,
An operation piece 22 that is disposed on the back surface of the handle 10 facing the door surface 1d and whose base end 22a is located near the swinging end of the handle 10 and that is movable in the thickness direction near the back surface of the handle 10. When,
An engagement piece 23 provided on the distal end 22b side of the operation piece 22 and protruding toward the door surface 1d;
An operating piece that is provided at the swinging base end of the handle 10 via a pivot so as to be swingable, extends into the lock mechanism 4 having the engaging rod 5, and outputs an unlocking operation to the lock mechanism 4. 25,

The operation is performed by grasping the handle 10, and the engaging piece 23 and the interlocking piece 27 are engaged with each other so that the operating piece 25 to which the operating force is directly transmitted into the lock mechanism 4 is substantially integrated with the handle 10. Since the opening operation of the door 1 can be performed, the opening operation of “push” on the door 1 requires a previous operation of grasping the operation piece 22, so that the rapid opening of the door 1 in the opening direction is suppressed. Then, it is possible to prevent an accident that occurs when the door 1 is vigorously opened, such as an accident that causes the door 1 to collide with a person on the other side of the door 1.
[0012]
Further, even if the opening operation is only to press the handle 10 without grasping the operation piece 22, the swing of the handle 10 is operated by pressing the handle 10 further, that is, the handle 10 can be moved in two stages. By performing an operation such as pressing, the contact portion 14d and the engaging piece 23 are configured to be engaged so that the operating piece 25 is substantially integrated with the handle 10. The opening operation of "" requires not only a simple pressing but also an operation of further pushing, so that even if the door 1 is suddenly opened in the opening direction, the door 1 is immediately opened. As described above, it is possible to prevent an accident caused by opening the door 1 vigorously, such as an accident that causes the person on the other side of the door 1 to collide with the door 1 as described above. .
[0013]
According to the structure of the door according to claim 2, the handle 10 is formed in a substantially plate shape, and has an arm portion 14 formed on a back surface facing the door surface 1d so as to project orthogonally to the back surface. The leading end of the arm 14 is the swing base end, and is pivotally attached to the door surface 1d side. The engaging piece 23 and the interlocking piece are formed in a tubular hollow portion 14b formed in the arm 14 in the longitudinal direction. 27 and the contact part 14d are arranged.
[0014]
According to such a door structure, the mechanism portion is hidden without the engagement piece 23, the interlocking piece 27, and the contact portion 14d being exposed to the outside in the arm portion 14 of the handle 10, and the appearance is improved. Is not reduced.
[0015]
According to the door structure of the third aspect, the pivot also serves as the swing center axis 18 of the handle 10.
[0016]
According to such a door structure, the swing center of the handle 10 and the swing center of the operation piece 25 can be constituted by one member, and it is possible to obtain a simple structure.
[0017]
According to the door structure of the fourth aspect, the operating piece 22 is provided with an urging member 24 that urges the handle 10 in a direction to be detached from the back surface of the handle 10.
[0018]
According to such a door structure, the operating piece 22 is always urged in the detaching direction on the back surface of the handle 10, the engaging piece 23 is not moved, and the operating piece 25 swings via the interlocking piece 27. The opening operation of the door 1 by pushing the handle 10 vigorously is performed while maintaining the state in which no movement is performed, that is, the state in which the engaging piece 23 and the interlocking piece 27 are not in the engaged state. An operation such as a further push-in operation is maintained in a required state instead of a pressing operation, and a state where the door 1 is not easily opened by a sudden push-open operation is maintained.

In this state, the tip 25b of the operation piece 25 is in contact with the interlocking portion 26 of the lock mechanism 4.
[0037]
In the door structure of the present invention, there are two types of methods: a method in which the door 1 is opened by grasping and pressing the lever handle 10 and a method in which the door 1 is opened only by pressing the pressing portion 11 of the lever handle 10. There is an operation method.
[0038]
First, an operation procedure for grasping and holding the lever handle 10 and opening the door 1 will be described. To open the door 1, first, an operator who wants to open the grip portion 13 of the lever handle 10 grips the door 1. By gripping the grip portion 13, the operation piece 22 located on the back surface of the grip portion 13 is operated in a pulling direction opposite to the pressing direction on the pressing portion 11, and resists the urging force of the compression coil spring 24. To enter the concave portion 12 on the back surface of the pressing portion 11. At this time, since the fingertip side at the time of grasping is the swing end (tip 22b) side of the operation piece 22, the operation piece 22 is easily swung.
[0039]
As shown in FIG. 4, as the operation piece 22 enters the recess 12, the engagement piece 23 is engaged with the interlocking piece 27.
[0040]
Next, the operator presses the pressing portion 11 of the lever handle 10 to swing around the shaft support portion 15. At the time of this swing operation, since the engagement piece 23 of the operation piece 22 is engaged with the interlocking piece 27, the interlocking piece 27 swings about the swing shaft 18, ie, the lever handle. 10, the operating piece 22, the engaging piece 23, the interlocking piece 27, and the operating piece 25 are substantially integrated, and the operating piece 25 swings with respect to the swing shaft 18, and the swing of the lever handle 10 causes the lock. The inside of the mechanism section 4 is swung. As a result, as shown in FIG. 5, the operating piece 25 swings by a predetermined angle (α in FIG. 5) to press the interlocking portion 26, and the latch bolt 5 interlockingly connected to the interlocking portion 26 is retracted. That is, the door 1 is released from the state where the latch bolt 5 holds the lock.
[0041]
The unlocked state of the door 1 is lifted in the opening direction by the opening operation of the operator holding the lever handle 10 and applying a pressing force to the lever handle 10, that is, the pressing operation. It swings around the hinge 3 of 1a.
Then, by directly pushing the door 1 in the opening direction, the door 1 is opened.
[0042]
Next, an operation procedure for performing an opening operation without holding the grip portion 13 of the lever handle 10 when opening the door 1 will be described.
First, an operator who wants to open the door 1 presses the pressing portion 11 of the lever handle 10 from the front.
[0043]
The lever handle 10 swings about the pivot 15 by the pressing operation. The operation piece 22 does not move because it is not gripped by the operator, and the engagement piece 23 and the interlocking piece 27 remain in a non-engaged state. That is, when the lever handle 10 swings, the lever handle 10 can swing with respect to the interlocking piece 27 and the operating piece 25. The swing of the lever handle 10 causes the engagement piece 23 to move away from the position facing the interlocking piece 27. That is, the interlocking piece 27 does not swing, and the arm 14 swings with respect to the interlocking piece 27 by the hollow portion 14 b of the arm 14.
[0044]
When the lever handle 10 swings and swings to a predetermined angle (β in FIG. 6), the tip 27a of the interlocking piece 27 is engaged with the contact portion 14d in the hollow portion 14b.
[0045]
Then, when the lever handle 10 is further pressed to swing, the interlocking piece 27 engaged with the contact portion 14d swings together with the swing of the lever handle 10, as shown in FIG. As a result, the operating piece 25 swings by a predetermined angle (γ in FIG. 7) to press the interlocking portion 26 of the lock mechanism 4, and the latch bolt 5 interlockingly connected to the interlocking portion 26 is retracted. That is, when the lever handle 10 is swung more than the normal operation (arrow P in FIG. 7), the door 1 is released from the state in which the latch bolt 5 is kept locked.
[0046]
The unlocked state of the door 1 is opened by the operator applying a pressing force to the lever handle 10, that is, by the pressing operation, about the hinge 3 of the hanging base 1 a in the opening direction. Rocks.
Then, by directly pushing the door 1 in the opening direction, the door 1 is opened.
[0047]
Therefore, according to the structure of the door configured as described above, in the opening operation for the door 1 that is opened by pushing, the operating piece 22 is provided on the lever handle 10 that swings by pushing and retracts the latch bolt 5. The operating piece 22 is operated by gripping the gripping portion 13 of the lever handle 10, and the operating piece 25, whose operating force is directly transmitted to the interlocking portion 26 in the lock mechanism 4, is substantially integrated with the lever handle 10. Since the engagement piece 23 and the interlocking piece 27 are engaged with each other, the door opening operation can be performed. , The sudden opening of the door 1 in the opening direction is deterred, and the door 1 is swiftly opened in an accident such as a collision of a person on the other side of the door 1 with the door 1. Accidents that occur in It is possible to prevent in.
In particular, since the swing base end of the operation piece 22 is disposed on the grip portion 13 side, the fingertip side when gripping the lever handle 10 becomes the swing end (22b), which corresponds to finger movement. Therefore, it is possible to suppress the consciousness of swinging the operation piece 22.
[0048]
Further, even if the opening operation is only to press the lever handle 10 without grasping the operation piece 22, the swing operation of the lever handle 10 is further performed by pressing the lever handle 10 so as to be pushed further. By performing an operation of pressing in two stages, the operating piece 25 is configured to be in a regulated state so as to be substantially integrated with the lever handle 10, so that the opening operation of “pressing” the door 1 can be simply performed. In addition to pressing, the door 1 is required to be pushed further. Therefore, even if the door 1 is suddenly opened in the opening direction, the door 1 is not opened immediately but is suppressed. It is possible to prevent an accident caused by opening the door 1 vigorously, such as an accident that causes the door 1 to collide with a person on the other side of the door 1. Further, since the door can be opened by performing the operation of further pushing, for example, when the operation piece 22 cannot be grasped and held, or when the operation piece 22 cannot be grasped and held, that is, for a person without grip strength, It can respond to a person holding luggage in both hands, etc., and can solve such a problem that the door is suddenly opened even in the opening operation of such a person. Can be opened.
[0049]
In the above-described embodiment, an example has been described in which the pressing portion 11 which is a pressed portion of the lever handle 10 has a substantially rectangular plate shape. However, the shape of the lever handle 10 is not limited to this. Instead, the shape may be other shapes such as a circle, an ellipse, and a polygon, and may be formed not in a plate shape but in a frame shape, for example. However, the shape is not limited to the above.
Further, the shape of the arm portion 14 constituting the lever handle 10 is not limited to the shape in the above embodiment.
[0050]
Furthermore, in the above-described embodiment, an example has been described in which the orientation of the gripping portion 13, which is the swinging tip of the lever handle 10, with respect to the pivotal support portion 15 is directed from the door tip 1 b of the door 1 to the hanging base 1 a. Regarding the attachment state of the lever handle 10 to the door 1, the extending direction of the grip portion 13 with respect to the shaft support portion 17 may be configured from the hanging base 1a to the door tip 1b side, or may be set to another direction. Even with this configuration, the same operation and effect as described above can be obtained.

As described above, in the door structure according to the present invention, in the opening operation of the door that is opened by pushing, the operating piece is provided on the handle that swings by pushing and retreats the engaging rod, and this operating piece is put together with the handle. Operated by grasping, the operating piece that directly transmits the operating force into the lock mechanism is engaged with the connecting piece of the engaging piece so that it is almost integrated with the handle, and the door can be opened. Since the opening operation of “pushing” on the door requires a previous operation of grasping the operation piece, the sudden opening of the door in the opening direction is suppressed, and the person on the other side of the door opens the door. It is possible to prevent accidents caused by opening the doors vigorously, such as an accident that causes a collision.
[0052]
In particular, by disposing the base end of the operation piece on the swinging end side of the handle, the fingertip side when grasping the handle becomes the moving end side of the operation piece and corresponds to the movement of the finger, so the operation piece is It is possible to suppress the consciousness of moving.
[0053]
In addition, even if the opening operation is only to press the handle without grasping the operation piece, the swinging of the handle is performed by pressing the handle further, that is, the handle is pressed in two stages. By performing the operation, the contact portion and the interlocking piece are engaged so that the operating piece becomes substantially integral with the handle, so that the opening operation of “push” to the door is simply pressed. Not only that, but it also requires an operation to push the door further, so that the sudden opening of the door in the opening direction is suppressed as in the above case, and the door may collide with the person on the other side of the door. It is possible to prevent accidents that occur due to violent opening of the vehicle.
[0054]
Further, since the door can be opened by performing the operation of further pushing, for example, it is possible to cope with a case where the operation piece cannot be grasped and held or a case where the operation piece cannot be grasped. It is possible to eliminate a problem such as a sudden opening of a door, and the door can be opened.
