Description

【０００１】
【発明の属する技術分野】
本発明は、ドアの開け閉め操作のみで該ドアの開き状態を維持したり、解除したりする床付け戸当たりに関するものである。
【０００２】
【従来の技術】
従来、家屋の各部屋に設置されるドアを開く際、壁面への激突を防止すると共に、開き状態に維持する手段として、床付け戸当たりが知られている。一般的には、激突を避ける壁の手前の床面にドアと対向する面に緩衝材を付設すると共にリング状の係り具を設けた床付け戸当たりと、ドアの略先端部に付設される該係り具が架かるフック状の係合部材とからなるものが使用されている。
【０００３】
近年、改良された種々の形態の戸当たりが提案されている。特許文献１の特開２０００−４５６０６号公報には、床に固定する戸当たり本体と、ドアに固定し、該戸当たり本体の上端部と保持可能に形成した係止体とから構成し、戸当たり本体、係止体のいずれか一方に保持力調整手段を配設した戸当たりが開示されている。また、特許文献２の特開２０００−２４８８０８号公報には、弾性材料製の戸当たり部に、扉に設けられた磁着部を磁着するマグネットあるいは磁性材料製の扉仮保持部を係合させ並設してなる戸当たり装置が開示されている。また、特許文献３の特開平１０−３２５２７４号公報には、戸当たり本体を床面に固定する固定体と、ばねにより上方に付勢されながら固定体に上下方向に摺動可能に配設され、足の踏み面により操作可能な形状に形成した、ストッパーを係止する可動係止体と、戸当たり本体の最外周に配設した緩衝体とで構成した戸当たりが開示されている。これらの戸当たりはいずれもドアの開き操作のみで戸当たり本体と係止体が仮止め又は保持される点で有用なものである。
【０００４】
【発明が解決しようとする課題】
しかしながら、特開２０００−４５６０６号公報や特開平１０−３２５２７４号公報に記載の戸当たりは、戸当たり本体と係止体の係合が上下方向に付勢する弾性体によるものであり、戸当たり形状が上下方向で大きくなり見栄えが悪いという問題がある。また、係合体やストッパーの先端が室内側に突出しているため、安全とは言い難くまた同様に見栄えが悪いという問題がある。また、特開２０００−２４８８０８号公報記載の戸当たりはドアが戸当たり部に激しく当たるような場合には、弾性材料が付設されているものの、仮保持が困難となる場合があると共に、結局はフック部材による保持であるため、保持状態を解除するには腰をかがめての手動作や足での解除操作が必要となり面倒である。
【０００５】
従って、本発明の目的は、係止体（ピン）に対するバネ付勢を水平面内で行なうことにより本体形状を扁平状とすると共に、ドアの開け閉めのみで確実なドアの開放状態の保持と開放状態の解除を行なうことができる戸当たりを提供することにある。

【課題を解決するための手段】
すなわち、本発明の床付け戸当たりは、ドアに固定されるストライクと、床面に固定される戸当たり本体部とからなるものであって、該戸当たり本体部は、短軸枠体の天板略中央の貫通穴と、該ストライクのピンが出入りするピン開口部の入口を形成する該天板より低い位置で該貫通穴に隣接してピン入口側に付設される開口部基板を有するものであり、該貫通穴と該ピン開口部で平面視が帯状の開口を形成する縦状の短軸枠体と、一端が軸支され該短軸枠体内であって該天板の裏面の所定位置にバネ付勢により配設されピンの押圧力によりバネ付勢に抗して所定角度回動するアーム部材と、該短軸枠体に外接で回動自在に遊嵌すると共に該アーム部材の先端係合部との係合により所定角度回動して前記ピン開口部の入口を開状態又は閉状態にするリング状回動体を備えることを特徴とする。
【０００８】
【発明の実施の形態】

【０００９】
本例の床付け戸当たり１０は、ドアに固定されるストライク１０ｂと、床面側に固定される戸当たり本体部１０ａとからなる。戸当たり本体部１０ａは、床面に固定されると共に短軸枠体１をネジ止めする底板６と、リング状回動体２を回動させる機構、すなわち、アーム部材３、バンパー部材４、ラチェット５及びトーションバネ８を収納する縦状の短軸枠体１と、リング状回動体２と、蓋材７とからなる。
【００１０】
底板６は円形薄板であって３箇所のネジ孔６２と１箇所の小ネジ孔６３と端方向に付設されるボス６１とからなる。ネジ孔６２は短軸枠体１と底板６を通って床面に達するネジ９を通す孔であり、小ネジ孔６３は短軸枠体１と底板６を固定する小ネジ６４を通す孔である。
【００１１】
短軸枠体１は中央を横断する帯び状の開口１８を有する円形枠体であって、所定強度を有し３個のネジ孔１４を有する天板１９と、開口１８と側周面１９１に形成されたアーム部材回動用切欠１７とで形成されるアーム部材３の回動空間１８１と、天板１９の裏面とで所定高さのレール溝１２を形成すると共にピン開口部の入口とバンパー係止止め端部１３を形成する開口部基板１１を備える。すなわち、帯び状の開口１８は天板略中央の貫通穴とピン開口部（開口部基板１１の上面）で形成される開口である。短軸枠体１はピン開口部の入口を開閉させるアーム部材３の作動が水平面内であるため、高さ方向の寸法を短くできる。このため、リング状回動体２が嵌めこまれても扁平状にでき、意匠性に優れた戸当たり本体部とすることができる。
【００１２】
バンパー部材４は前段部材４２とこれより高い中央部材４１とこれより低いが前段部材４２より高い後段部材４５の表面段差部材と、裏面中央に下方に突出するアーム部材当接部４３とからなる。該バンパー部材４の幅寸法は、短軸枠体１の開口１８の幅よりやや小さく、且つ前段部材４２の厚みがレール溝１２の高さより小さく設定されている。このようなバンパー部材４は中央部材４１の前面部がピンの押圧を受けるピン当接部となり、前段部材４２がレール溝１２にスライド自在に嵌合するスライド体となる。
【００１３】
アーム部材３は短軸枠体１の一方の天板１９の裏面に付設されるボス１９２に一端が軸支されるケース体３２と、該ケース体３２にバネ３４を介して遊嵌すると共に先端側に付勢される先端がフック形状３６の先端係合部３３を備える。ラチェット５はリング状回動体２が回動した後、アーム部材３がトーションバネ８により元の位置に戻される際、連れ回りすることを防止するものであり、短軸枠体１のボス１９２に一端が軸支される本体部５２と、短軸枠体１の突起部（不図示）に係合する係合凹部５３と、リング状回動体２の裏面に形成された鋸刃状の係合溝２３に係合するラチェット片５１からなる。
【００１４】
リング状回動体２は、短軸枠体１に外接で回動自在に遊嵌し、側周面が内側に上りとなる勾配を有する傾斜面である壁部２１と開口部２２の繰り返し構造であって、本例では壁部２１と開口部２２がそれぞれ４５度の間隔で配設される繰り返し構造である。裏面には表面にある壁部２１と開口部２２の合計数と同じ個数の鋸刃状の係合溝２３を等ピッチ、すなわち、４５度間隔で形成する（図２参照）。リング状回動体２は側周面が内側に上り勾配の傾斜面を有するため、後述するバネ付勢に抗して没入自在のストライクピンを用いれば、誤作動によりピン開口部が閉じた状態が待機状態の場合であっても、該ピンは側周面に沿って上昇しピン拘束位置に落とすことができる。また、蓋材７は短軸枠体１の開口部と略同じ形状の開口７１を有するキャップであり、側面下方の係合突起７２と短軸枠体１の嵌合溝１６が着脱自在に嵌合する。
【００１５】
このような構成部品からなる戸当たり本体部１０ａを組み付けるには、例えばアーム部材３の上面にバンパー部材４の後段部材４５を乗せて（図３及び図４）、アーム部材３の軸孔３１を短軸枠体１のボス１９２に嵌め込む。この際、バンパー部材４を短軸枠体１の開口１８に入り込ませると共に、前段部材４２をレール溝１２に嵌めこむ。次いでラチェット５を短軸枠体１のボス１９２に嵌め込み更に係合凹部５３を短軸枠体１の係合突起（不図示）に嵌め込む。このように、短軸枠体１、バンパー部材４、アーム部材３及びラチェット５を仮組み付けした後、底板６のボス６１を短軸枠体１のボス孔１５に挿入し、短軸枠体１と底板６を小ネジ６４で一体化させる。次にトーションバネ８をその孔部をボス６１に差し込みアーム部材３を短軸枠体１に対してピン開口１１１側とは反対方向に付勢するように取り付ける。これにより、アーム部材３はその一方の側面３５がバンパー部材４のアーム部材当接部４３の後方面を押し付け、アーム部材当接部４３の前方面が短軸枠体１の開口部基板１１の後方端面１３に当接することで停止する。この状態でバンパー部材４の前段部材４２の前方が空くためピン開口部Ｘを構成することになる。
【００１６】
このようなリング状回動体２と蓋材７以外を組み込んだ中間組み付け体１０ｃを得る（図５）。次いで中間組み付け体１０ｃにリング状回動体２を短軸枠体１の外周部に沿うように置く。リング状回動体２の内径は短軸枠体１の外径よりもやや大きいため、リング状回動体２は短軸枠体１に容易に嵌め込むことができる。この際、アーム部材３はバネ３４の付勢でその長さが最大であり、係合部３３の先端部がリング状回動体２の裏面の係合溝２３ｄに係合している（図６）。次いでこの組み付け体を床面の所定位置に置き、３本のネジ９で床面に固定する。その後、蓋材７をその係合突起７２が短軸枠体１の蓋材嵌合溝１６に嵌るように蓋をする。これにより戸当たり本体部１０ａの組み付けが完了する。このような戸当たり本体部１０ａは、短軸枠体１に嵌められたリング状回動体２の裏面位置が、底板の裏面から０．３〜３．０ｍｍ、好ましくは０．３〜１．０ｍｍ離れていることが、床面が完全な平坦面でない場合もありリング状回動体２と床面の摩擦を回避でき、安定した回動が実現できる点で好ましい。
【００１７】
また、本例の戸当たり本体部１０ａにおいて、バンパー部材４を省略し、アーム部材３にストライクピン１０１が直接当たるようにしてもよい。この場合、短軸枠体１のピン開口部分にピン先端が当接する基板を設けることが、ピンの出入りを円滑にする点で好適である。
【００１８】
本例の床付け戸当たり１０の他の構成部材であるストライク１０ｂは、ドアに固定されストライクピンが下方に突出しているものであれば特に制限されない。本例のストライク１０ｂは、図１３及び図１４に示すように、本体部１０７と、ピン長さ調整部材１０３と、バネ１０５と、ストライクピン１０１と、ネジ部材１０２からなる。本体部１０７は４個のネジ孔１０４を有する取り付け部１０８と、上方側に所定高さで形成される星型断面の凹溝１０３ａ、及び下方側に所定長さで形成される雌ねじ（不図示）を有する嵌合部１０９とからなる。ピン長さ調整部材１０３は外形状が嵌合部１０９の凹溝１０３ａと嵌合すると共にバネ１０５の一部をその中に収納する筒状体である。また、星型断面の凹溝１０３ａは六角レンチや十字ドライバーで回転操作ができる形状の穴である。ストライクピン１０１はピン部１０１ｂとバネ１０５を嵌める突起部１０１ａとからなり、ピン部１０１ｂの上方にはネジ部材の係合凸部１１２と嵌合する係合凹部１１３を有する。ネジ部材１０２は外周が嵌合部１０９の雌ネジに螺合する雄ネジであり、内形状がストライクピン１０１のピン部１０１ｂを下方へ突出させる位置で支持すると共に内側に突出する係合凸部１１２とストライクピン１０１の係合凹部１１３と嵌合し、ストライクピン１０１を回動不能にしている。このような構造のストライク１０ｂはストライクピン１０１をバネ付勢に抗して没入自在とすることができる。
【００１９】
次に、ストライクピンの長さ調整方法について図１４を参照して説明する。図１４（Ａ）に示すストライク１０ｂはストライクピン１０１の長さが取り付け部１０８の下方端基準でＨ１のものである。この長さを短くする場合、先ず六角レンチＢをピン長さ調整部材１０３の凹溝１０３ａに挿入しバネ１０５の付勢に抗して押し込む。すると、ピン長さ調整部材１０３と嵌合部の雌ネジとの螺合が外れる（Ｂ）。この場合長さ調整部材１０３、ストライクピン１０１及びネジ部材１０２は一体化している。このため、六角レンチＢを図１４の（Ｃ）に示すように左回しするとネジ部材１０２は嵌合部の雌ネジが右ネジであるため、嵌合部１０９の中に入り込む。適宜の長さＨ２となったら六角レンチＢを凹溝１０３ａから引き抜く。この際、ピン長さ調整部材１０３はバネ１０５の付勢により上方に押しやられストライクピン１０１から離れて再び嵌合部の雌ネジに螺合する。Ｈ１長さを長くするには図（Ｃ）における六角レンチの回転を右回りにするだけでよい。
【００２０】
次に床付け戸当たり１０の作動機構を図６〜図１２を参照して説明する。図６及び図９はフリーの状態（待機状態）における床付け戸当たりである。フリー状態ではバンパー部材４はピン開口側に付勢されており前段部材４２と開口部基板１１でピン開口部Ｘを形成している。すなわち、ピン開口部Ｘにはリング状回動体２の開口部２２ａが位置している。この状態でドアＡが開かれストライクピン１０１がピン開口部Ｘに入ってくる。ピン１０１の押圧力によりバンパー部材４の前段部材４２がバネ付勢に抗して後方に押され、アーム部材当接部４３がアーム部材３を更に押すためアーム部材３はボス１９２を中心に回動する。アーム部材３の先端係合部３３はリング状回動体２の係合溝２３ｄと係合しているため、リング状回動体２も回転する（図７）。アーム部材３の回動範囲は本例では短軸枠体１のアーム部材回動用切欠１７で規制されるリング状回動体２を４５度回動させる範囲である（図８）。また、ラチェト片５１は最初の係合溝２３ｈから後方の係合溝２３ｇに係合する。この際、ピン開口部Ｘにはリング状回動体２の壁部２１ｄが位置して開口を閉じる（図１０）。
【００２１】
ドアＡの押圧が無くなると、トーションバネ８の付勢によりアーム部材３が元の位置に戻されバンパー部材４もピン入口側に戻される。この際、先端係合部３３は係合溝２３ｃに係合する。また、ラチェット片５１は係合溝２３ｇに係合しているため、リング状回動体２はアーム部材３の戻りに同期して連れ回ることはない。これにより、ドアＡは開状態でロックされる（図１１）。
【００２２】
次に、ドアＡを開状態とするロックを解除する。今度はドアＡを更に開ける方向に押すと、最初の作動順序と同様にピン１０１の押圧力によりバンパー部材４の前段部材４２がバネ付勢に抗して後方に押され、アーム部材当接部４３がアーム部材３を更に押すためアーム部材３はボス１９２を中心に回動し、リング状回動体２も同様の方向に回転する。すなわち、図では省略するが、アーム部材３の先端係合部３３は係合溝２３ｃに係合しながらリング状回動体２を４５度回動させる。ラチェト片５１は係合溝２３ｇから後方の係合溝２３ｆに係合する。この際、ピン開口部Ｘにはリング状回動体２の開口部２２ｄが位置して開口を開ける（図１２）。
【００２３】
ドアＡが戸当たり本体部１０ａから解放され離れると、トーションバネ８の付勢によりアーム部材３が元の位置に戻されバンパー部材４もピン入口側に戻されて、元のフリーの状態になる。以後は、フリー状態、ドアＡの開きによる押圧、停止及び再押圧の各動作の繰り返しにより、リング状回動体２が停止状態から同方向に４５度毎回転し、ピン開口部Ｘは開状態と閉状態の繰り返しとなる。
【００２４】
第１の実施の形態における床付け戸当たり１０によれば、係止体（ピン）に対するバネ付勢を水平面内で行なうため、本体形状を扁平状にできると共に、リング状回動体の所定角度の回動によりピン開口部を直接的に開状態又は閉状態にするため、ドアの開け閉めのみで確実なドアの開放状態の保持と開放状態の解除を行なうことができる。
【００２５】
次に本発明の第２の実施の形態における床付け戸当たりを図１５〜図２０を参照して説明する。図１５は本例の戸当たり本体部の分解図、図１６は蓋材及び中間組み付け体に分解した図、図１７（Ａ）はストライクピンを拘束する状態におけるリング状回動体とアーム部材の関係を示す図、（Ｂ）は（Ａ）のＢ−Ｂ線に沿って見た図、図１８（Ａ）はストライクピンの再押圧を受けた最大作動状態におけるリング状回動体とアーム部材の関係を示す図、（Ｂ）は（Ａ）のＢ−Ｂ線に沿って見た図、図１９（Ａ）は待機状態におけるリング状回動体とアーム部材の関係を示す図、（Ｂ）は（Ａ）のＢ−Ｂ線に沿って見た図、図２０（Ａ）はフリー状態におけるストライクと戸当たり本体部の関係を示す図、（Ｂ）はストライクピンの押圧を受けピン開口部が閉じた状態におけるストライクピンと戸当たり本体部の関係を示す図、（Ｃ）はドアを開状態に拘束する状態図で図１７に対応する図、（Ｄ）は開状態で拘束されたドアを無拘束にする状態図で図１９に対応する図である。なお、図１７〜図１９は短軸枠体の表側部材及びピン開口部Ｘを開閉する回動板を透視した図である。
【００２６】
本第２の実施の形態例の床付け戸当たりにおいて、第１の実施の形態例の床付け戸当たりと相違する主たる点は、戸当たり本体部において、リング状回動体を短軸枠体内のリング溝に遊嵌する、いわゆる内接型とした点、リング状回動体の回動により回動板を倒伏さえたり起立させたりして間接的にピン開口部Ｘを開閉するようにした点にある。すなわち、戸当たり本体部１００ａは床面に固定される底板６００と、リング状回動体３００を回動させる機構、すなわち、アーム部材５００及びトーションバネ５１０を収納する扁平状の短軸枠体２００と、短軸枠体２００に回動自在に取り付けられる倒伏又は起立によりピン開口部Ｘを開閉する回動板４００と、蓋材７００からなる。
【００２７】
底板６００は円形薄板であって３箇所のネジ孔６０１と、３箇所の小ネジ孔６０２と、周端面の一部に起立する板状のバネ部６０４を有する係合板壁材６０３とからなる。ネジ孔６０１は短軸枠体２００と底板６００を通って床面に達するネジ１１０を通す孔であり、小ネジ孔６０２は短軸枠体２００と底板６００を固定する小ネジ９００を通す孔である。
【００２８】
短軸枠体２００は中央に位置する段差を有する薄厚基板２０３で分断される２つの開口２０２、２０４を有する扁平状の円錐枠体であって、所定強度を有し３個のネジ孔２１５を有する天板２０１と、裏面に偏心して段差状に付設されるリング状回動体３００が遊嵌するリング溝２１７と、トーションバネが取り付けられるボス２０７と、底板に付設された係合板壁材６０３が嵌め込まれる溝２１９を備える。段差状のリング溝２１７の表側の深溝部は遊嵌するリング状回動体３００の山状突起部３０１が遊嵌する溝である。薄厚基板２０３の底板２１６と開口２０２はアーム部材５００が水平方向に所定の角度回動する略扇形の回動空間を形成し、略扇形の要の位置にある短軸枠体２００には雌ネジ穴を有する筒状体２０８が付設されている。開口２０４は矩形状の回動板４００よりやや大きい開口であり、該開口２０４の両側にある短軸枠体２００の裏面には回動軸４０２が嵌合する軸穴２０６が付設されている。また、開口２０４周りはその前方に薄板開口板２０５を、後方に薄板基板２０３を有し、回動板４００が嵌め込まれ倒伏した状態で表面部分がピンが円滑に出入りするような同一水平面を構成する。短軸枠体２００はピン開口部Ｘを開閉させる回動板４００を倒伏又は起立させるアーム部材５００の作動が水平面内であるため、高さ方向の寸法を短くできる。このため、リング状回動体３００が嵌めこまれても扁平状にでき、意匠性に優れた戸当たり本体部とすることができる。
【００２９】
アーム部材５００は短軸枠体２００に付設される筒状体２０８に嵌合するネジ穴５０４と、アーム本体部５０１と、アーム本体部中央側面に立設する半円筒状の当接部５０２と、深い切り込みにより弾発性を持たせた先端係合片５０３を備える。また、アーム部材５００の裏面は段差状であり、アーム部材５００が筒状体２０８に嵌合すると、短軸枠体２００の開口２０２と薄厚基板２０３で形成される底板２１６の段差形状に沿って水平状に載置されるようになっている。
【００３０】
リング状回動体３００は、短軸枠体２００の裏面に形成された段差を有するリング溝２１７に埋没するように且つ回動自在に遊嵌し、表面には６０度の等間隔で配設される山状の突起部３０１を有し、内周面には１２個の鋸刃状の係合溝３０２を等ピッチ、すなわち、３０度間隔で形成すると共に、外周面には１２個の係合凹部３０４を形成する（図１５参照）。また、蓋材７００は短軸枠体２００のピン開口部と略同じ形状の開口７０２を有するキャップであり、側面前方の係合突起７０１と短軸枠体２００の嵌合溝２１８が着脱自在に嵌合する。回動板４００は略矩形状であり、一端両側には回動軸４０２を有すると共に、裏面にはリング状回動体３００の幅寸法よりやや大きな切欠部４０３を有している。
【００３１】
このような構成部品からなる戸当たり本体部１００ａを組み付けるには、例えば回動板４００を開口２０４の下方から入れ込み、回動軸４０２を短軸枠体２００の軸穴２０６に嵌め込み、次いで短軸枠体２００のリング溝２１７にリング状回動体３００を嵌め込む。リング状回動体３００及び回動板４００は共に、手で下支えしないと下方に脱落する。このため、この２部材を短軸枠体２００に取り付けた後は底板６００を取り付けるのがよい。底板６００は各ネジ穴を短軸枠体２００のネジ穴に合わせると共に、係合板壁材６０３を溝２１９に嵌め込む。更に、アーム部材５００の軸穴５０４を筒状体２０８に回動自在に嵌め込み、ネジ８００でネジ止めして脱落を防止する。アーム部材５００の先端係止片５０３はリング状回動体３００の係合溝３０２に係合させる。次いでトーションバネ５１０をボス２０７に係合させ、アーム部材５００をピン開口側に付勢するように配設する。次いで３本のネジ１１０で短軸枠体２００と底板６００を貫通して床面に固定する。そして最後に蓋材７００を取り付けて組み付けを完了する。この状態は待機状態であり、アーム部材５００は短軸枠体２００の底板２１６のピン開口部Ｘ側に当接した状態であり、且つ回動板４００が倒伏状態であるため、ピン開口部Ｘは側方向に空いている（図２０（Ａ））。

次に床付け戸当たり１００ａの作動機構を図１７〜図２０を参照して説明する。図１７〜図１９ではストライクピン拘束状態から開放状態に至る作動機構を説明する。図１７及び図２０（Ｃ）はストライクピン拘束状態における床付け戸当たり１００ａである。この状態でドアＡは開状態であり、ストライクピン１０１はピン拘束位置Ｙにあると共に、ピン開口部Ｘにはリング状回動体３００の山状突起３０１が位置して回動板４００を斜め傾斜まで起こすため、開口を閉じている（図１７（Ｂ）、図２０（Ｃ））。次いで、ストライクピン１０１の拘束を解くには、ピン１０１の再押圧力によりアーム部材５００をバネ付勢に抗して後方に押す（図２０（Ｄ））。これにより、アーム部材５００はボス２０８を中心に回動する。アーム部材５００の先端係合片５０３はリング状回動体３００の係合溝３０２と係合しているため、リング状回動体３００も回転する（図１８）。アーム部材５００の回動範囲は本例では短軸枠体２００の基板２１６の扇形形状で規制され、リング状回動体３００が３０度回動したところで停止する。従って、ピン開口部Ｘにはリング状回動体３００の山状突起が無い平坦部がくるため、回動板４００は支えが無くなり重力により倒伏する。このため、ピン開口部Ｘは側方向に空くため、ストライクピン１０１が拘束状態から解かれる。この際、ドアＡの押圧が無くなると、トーションバネ５１０の付勢によりアーム部材５００が元の位置に戻され、先端係合片５０３は後ろの係合溝３０２に係合する。また、ラチェット機能を有するバネ片６０４は係合溝３０４に係合しているため、リング状回動体３００はアーム部材５００の戻りに同期して連れ回ることはない。これにより、戸当たり本体部１００ａは元の待機状態となる（図１９、図２０（Ａ））。以後は、第１の実施の形態と同様に、停止（ピンの拘束）、再押圧、フリー状態、ドアＡの開きによる押圧の各動作が繰り返えされ、リング状回動体３００が停止状態から同方向に３０度毎回転し、ピン開口部Ｘには山状突起部３０１が来たり消えたりするため、回動体４００は倒伏と傾斜起立の繰返しで、その結果ピン開口部Ｘは開状態と閉状態の繰り返しとなる。本例の戸当たり本体部１００ａは、リング状回動体３００のアーム状部材５００と係合する係合溝３０２及び山状突起部の配設ピッチ３０１は上記３０度に限定されず、適宜決定される。
【００３３】
第２の実施の形態における床付け戸当たりによれば、係止体（ピン）に対するバネ付勢を水平面内で行なうため、本体形状を扁平状にできると共に、内蔵されたリング状回動体の所定角度の回動によりピン開口部を間接的に開状態又は閉状態にするため、ドアの開け閉めのみで確実なドアの開放状態の保持と開放状態の解除を行なうことができる。
【００３４】
【発明の効果】
本発明によれば、係止体（ピン）に対するバネ付勢を水平面内で行なうことにより本体形状を扁平状とすると共に、ドアの開け閉めのみで確実なドアの開放状態の保持と開放状態の解除を行なうことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a flooring door stop that maintains or releases an open state of a door only by opening and closing the door.
[0002]
[Prior art]
Conventionally, when a door installed in each room of a house is opened, a flooring door stop is known as a means for preventing a collision with a wall surface and maintaining the opened state. In general, the floor surface in front of the wall to avoid a crash is provided with a cushioning material on the surface facing the door and a ring-like engagement member, and is attached to the front end of the door. What consists of a hook-shaped engaging member on which this engaging tool is hung is used.
[0003]
In recent years, various improved forms of door stop have been proposed. Japanese Patent Application Laid-Open No. 2000-45606 of Patent Document 1 includes a door stop main body fixed to a floor, an upper end portion of the door stop main body fixed to the door, and a locking body formed to be able to be held. A door stop in which holding force adjusting means is disposed on either the hit body or the locking body is disclosed. Further, in Japanese Patent Application Laid-Open No. 2000-248808 of Patent Document 2, a magnet that magnetically attaches a magnetically attached portion provided on a door or a temporary door made of a magnetic material is engaged with a door stopper made of an elastic material. A door stop device formed side by side is disclosed. Japanese Patent Laid-Open No. 10-325274 of Patent Document 3 is provided with a fixed body for fixing the door-stop main body to the floor surface, and slidable in the vertical direction on the fixed body while being urged upward by a spring. A door stop made of a movable locking body that locks a stopper, formed in a shape that can be operated by a foot tread surface, and a buffer disposed on the outermost periphery of the door-stop main body is disclosed. These door stops are useful in that the door stop body and the locking body are temporarily fixed or held only by the door opening operation.
[0004]
[Problems to be solved by the invention]
However, the door stop described in Japanese Patent Application Laid-Open No. 2000-45606 and Japanese Patent Application Laid-Open No. 10-325274 is due to an elastic body in which the engagement between the door stop main body and the locking body is urged in the vertical direction. There is a problem that the shape becomes large in the vertical direction and looks bad. Moreover, since the front ends of the engaging body and the stopper protrude toward the indoor side, there is a problem that it is difficult to say that it is safe and also looks bad. In addition, the door stop described in Japanese Patent Application Laid-Open No. 2000-248808 is provided with an elastic material when the door hits the door stop portion violently. Since it is held by the hook member, in order to release the holding state, it is necessary to perform a hand operation while bending down and a releasing operation with feet, which is troublesome.
[0005]
Accordingly, an object of the present invention is to make the body shape flat by performing spring biasing on the locking body (pin) in a horizontal plane, and to reliably hold and open the door by simply opening and closing the door. It is in providing the door stop which can perform the cancellation | release of a state.

[0009]
The flooring door stop 10 of this example includes a strike 10b fixed to the door and a door stop main body 10a fixed to the floor surface side. The door stop main body 10a is fixed to the floor surface, and has a bottom plate 6 for screwing the short shaft frame 1 and a mechanism for rotating the ring-shaped rotating body 2, that is, an arm member 3, a bumper member 4, and a ratchet 5. And the vertical short shaft frame 1 that houses the torsion spring 8, the ring-shaped rotating body 2, and the lid member 7.
[0010]
The bottom plate 6 is a circular thin plate, and includes three screw holes 62, one small screw hole 63, and a boss 61 attached in the end direction. The screw hole 62 is a hole through which the screw 9 that reaches the floor surface through the short shaft frame 1 and the bottom plate 6 is passed, and the small screw hole 63 is a hole through which the small screw 64 that fixes the short shaft frame 1 and the bottom plate 6 is passed. is there.
[0011]
The short-axis frame 1 is a circular frame having a band-shaped opening 18 crossing the center, and has a top plate 19 having a predetermined strength and three screw holes 14, and an opening 18 and a side peripheral surface 191. A rail groove 12 having a predetermined height is formed by the rotation space 181 of the arm member 3 formed by the formed arm member rotation notch 17 and the back surface of the top plate 19, and the entrance of the pin opening and the bumper engagement An opening substrate 11 that forms a stop end 13 is provided. In other words, the band-shaped opening 18 is an opening formed by a through hole and a pin opening (upper surface of the opening substrate 11) in the substantially center of the top plate. Short shaft frame 1 has pin opening Entrance Since the operation of the arm member 3 for opening and closing is within the horizontal plane, the height dimension can be shortened. For this reason, even if the ring-shaped rotating body 2 is fitted, it can be flattened and can be a door-stop main body having excellent design.
[0012]
The bumper member 4 includes a front member 42, a central member 41 higher than the front member 42, a front surface step member 45 which is lower than the front member 42 but higher than the front member 42, and an arm member contact portion 43 which protrudes downward in the center of the back surface. The width of the bumper member 4 is set to be slightly smaller than the width of the opening 18 of the short shaft frame 1, and the thickness of the front member 42 is set to be smaller than the height of the rail groove 12. In such a bumper member 4, the front surface portion of the central member 41 serves as a pin contact portion that receives the pressure of the pin, and the front member 42 serves as a slide body that is slidably fitted into the rail groove 12.
[0013]
The arm member 3 has a case body 32 whose one end is pivotally supported by a boss 192 attached to the back surface of one top plate 19 of the short shaft frame 1, and is loosely fitted to the case body 32 via a spring 34 and has a distal end. The tip urged to the side includes a tip engaging portion 33 having a hook shape 36. The ratchet 5 prevents the arm member 3 from being rotated when the ring-shaped rotating body 2 is rotated and then returned to the original position by the torsion spring 8. A main body 52 that is pivotally supported at one end, an engagement recess 53 that engages with a projection (not shown) of the short shaft frame 1, and a saw blade-like engagement formed on the back surface of the ring-shaped rotating body 2. The ratchet piece 51 is engaged with the groove 23.
[0014]
The ring-shaped rotating body 2 is a repetitive structure of a wall portion 21 and an opening portion 22 that are slanted surfaces that are freely fitted to the short shaft frame 1 so as to be freely turnable and have a gradient in which the side peripheral surface rises inward. In this example, the wall portion 21 and the opening portion 22 are each a repeated structure in which 45 ° intervals are provided. The same number of saw blade-like engagement grooves 23 as the total number of wall portions 21 and openings 22 on the front surface are formed on the back surface at equal pitches, that is, at intervals of 45 degrees (see FIG. 2). Since the ring-shaped rotating body 2 has an upwardly inclined surface on the inner side, if a strike pin that can be retracted against the spring bias described later is used, the pin opening portion may be closed due to a malfunction. Even in the standby state, the pin can be raised along the side peripheral surface and dropped to the pin restraining position. The lid member 7 is a cap having an opening 71 having substantially the same shape as the opening of the short shaft frame 1, and the engaging protrusion 72 below the side surface and the fitting groove 16 of the short shaft frame 1 are detachably fitted. Match.
[0015]
In order to assemble the door stop main body 10a made of such components, for example, the rear member 45 of the bumper member 4 is placed on the upper surface of the arm member 3 (FIGS. 3 and 4), and the shaft hole 31 of the arm member 3 is formed. Fit into the boss 192 of the short shaft frame 1. At this time, the bumper member 4 is inserted into the opening 18 of the short shaft frame 1, and the front member 42 is fitted into the rail groove 12. Next, the ratchet 5 is fitted into the boss 192 of the short shaft frame 1, and the engagement recess 53 is fitted into the engagement protrusion (not shown) of the short shaft frame 1. After the short shaft frame 1, the bumper member 4, the arm member 3 and the ratchet 5 are temporarily assembled in this way, the boss 61 of the bottom plate 6 is inserted into the boss hole 15 of the short shaft frame 1, and the short shaft frame 1 And the bottom plate 6 are integrated with a small screw 64. Next, the torsion spring 8 is inserted into the boss 61 through the hole, and the arm member 3 is attached to the short shaft frame 1 so as to be biased in the direction opposite to the pin opening 111 side. Thus, one side surface 35 of the arm member 3 presses the rear surface of the arm member abutting portion 43 of the bumper member 4, and the front surface of the arm member abutting portion 43 is the opening substrate 11 of the short shaft frame 1. It stops by contacting the rear end face 13. In this state, the front of the front member 42 of the bumper member 4 is vacant, so that the pin opening X is formed.
[0016]
An intermediate assembly 10c in which components other than the ring-shaped rotating body 2 and the lid member 7 are incorporated is obtained (FIG. 5). Next, the ring-shaped rotating body 2 is placed on the intermediate assembly 10 c along the outer peripheral portion of the short shaft frame 1. Since the inner diameter of the ring-shaped rotating body 2 is slightly larger than the outer diameter of the short shaft frame body 1, the ring-shaped rotating body 2 can be easily fitted into the short shaft frame body 1. At this time, the length of the arm member 3 is the maximum due to the bias of the spring 34, and the tip of the engaging portion 33 is engaged with the engaging groove 23d on the back surface of the ring-shaped rotating body 2 (FIG. 6). ). Next, the assembly is placed at a predetermined position on the floor surface and fixed to the floor surface with three screws 9. Thereafter, the lid member 7 is covered so that the engaging projection 72 fits into the lid member fitting groove 16 of the short shaft frame 1. Thereby, the assembly | attachment of the door part main-body part 10a is completed. In such a door-to-door main body 10a, the back surface position of the ring-shaped rotating body 2 fitted to the short shaft frame 1 is 0.3 to 3.0 mm, preferably 0.3 to 1.0 mm from the back surface of the bottom plate. It is preferable that they are separated from each other because the floor surface may not be a completely flat surface, and friction between the ring-shaped rotating body 2 and the floor surface can be avoided and stable rotation can be realized.
[0017]
Moreover, in the door stop main-body part 10a of this example, the bumper member 4 may be abbreviate | omitted and you may make it the strike pin 101 touch the arm member 3 directly. In this case, it is preferable to provide a substrate with which the tip of the pin comes into contact with the pin opening portion of the short shaft frame 1 in order to make the pins go in and out smoothly.
[0018]
The strike 10b which is the other structural member 10 per flooring door of this example is not particularly limited as long as it is fixed to the door and the strike pin protrudes downward. As shown in FIGS. 13 and 14, the strike 10 b of this example includes a main body 107, a pin length adjusting member 103, a spring 105, a strike pin 101, and a screw member 102. The main body 107 includes a mounting portion 108 having four screw holes 104, a star-shaped cross-sectional groove 103a formed at a predetermined height on the upper side, and a female screw (not shown) formed at a predetermined length on the lower side. ) Having a fitting portion 109. The pin length adjusting member 103 is a cylindrical body having an outer shape that fits into the concave groove 103a of the fitting portion 109 and accommodates a part of the spring 105 therein. The concave groove 103a having a star-shaped cross section is a hole having a shape that can be rotated with a hexagon wrench or a cross driver. The strike pin 101 includes a pin portion 101b and a protruding portion 101a for fitting the spring 105. The strike pin 101 has an engagement recess 113 that engages with an engagement projection 112 of a screw member above the pin portion 101b. The screw member 102 is a male screw whose outer periphery is screwed into the female screw of the fitting portion 109, and the inner shape supports the pin portion 101b of the strike pin 101 in a position where it protrudes downward, and the engagement convex portion protrudes inward. 112 and the engaging recess 113 of the strike pin 101 are fitted to make the strike pin 101 unrotatable. The strike 10b having such a structure can make the strike pin 101 immersable against the spring bias.
[0019]
Next, a method for adjusting the length of the strike pin will be described with reference to FIG. In the strike 10 b shown in FIG. 14A, the length of the strike pin 101 is H <b> 1 with respect to the lower end of the attachment portion 108. In order to shorten this length, first, the hexagon wrench B is inserted into the concave groove 103a of the pin length adjusting member 103 and pushed against the bias of the spring 105. Then, the screw connection between the pin length adjusting member 103 and the female screw of the fitting portion is released (B). In this case, the length adjusting member 103, the strike pin 101, and the screw member 102 are integrated. Therefore, when the hexagon wrench B is turned counterclockwise as shown in FIG. 14C, the screw member 102 enters the fitting portion 109 because the female screw of the fitting portion is a right-hand screw. When the appropriate length H2 is reached, the hexagon wrench B is pulled out of the groove 103a. At this time, the pin length adjusting member 103 is pushed upward by the urging force of the spring 105, is separated from the strike pin 101, and is screwed into the female screw of the fitting portion again. In order to increase the H1 length, the hexagon wrench in FIG.
[0020]
Next, the operation mechanism of the flooring door 10 will be described with reference to FIGS. 6 and 9 show the floor-to-door contact in a free state (standby state). In the free state, the bumper member 4 is biased toward the pin opening side, and the front stage member 42 and the opening substrate 11 form a pin opening X. That is, the opening 22a of the ring-shaped rotating body 2 is located in the pin opening X. In this state, the door A is opened and the strike pin 101 enters the pin opening X. The front member 42 of the bumper member 4 is pushed backward against the spring bias by the pressing force of the pin 101, and the arm member abutting portion 43 further pushes the arm member 3, so that the arm member 3 rotates around the boss 192. Move. Since the tip engaging portion 33 of the arm member 3 is engaged with the engaging groove 23d of the ring-shaped rotating body 2, the ring-shaped rotating body 2 also rotates (FIG. 7). In this example, the rotation range of the arm member 3 is a range in which the ring-shaped rotation body 2 regulated by the arm member rotation notch 17 of the short shaft frame 1 is rotated by 45 degrees (FIG. 8). Further, the ratchet piece 51 is engaged with the rear engagement groove 23g from the first engagement groove 23h. At this time, the wall portion 21d of the ring-shaped rotating body 2 is positioned in the pin opening portion X, and the opening is closed (FIG. 10).
[0021]
When the door A is no longer pressed, the arm member 3 is returned to its original position by the urging of the torsion spring 8, and the bumper member 4 is also returned to the pin inlet side. At this time, the tip engagement portion 33 engages with the engagement groove 23c. Further, since the ratchet piece 51 is engaged with the engaging groove 23g, the ring-shaped rotating body 2 is not rotated around in synchronization with the return of the arm member 3. Thereby, the door A is locked in the open state (FIG. 11).
[0022]
Next, the lock that opens the door A is released. Next, when the door A is pushed further in the opening direction, the front member 42 of the bumper member 4 is pushed backward against the spring bias by the pressing force of the pin 101 as in the first operation sequence, and the arm member contact portion Since 43 further pushes the arm member 3, the arm member 3 rotates about the boss 192, and the ring-shaped rotating body 2 also rotates in the same direction. That is, although omitted in the drawing, the tip engaging portion 33 of the arm member 3 rotates the ring-shaped rotating body 2 by 45 degrees while engaging the engaging groove 23c. The ratchet piece 51 is engaged with the rear engaging groove 23f from the engaging groove 23g. At this time, the opening 22d of the ring-shaped rotating body 2 is located in the pin opening X to open the opening (FIG. 12).
[0023]
When the door A is released from the door-contact main body 10a and separated, the arm member 3 is returned to the original position by the urging of the torsion spring 8, and the bumper member 4 is also returned to the pin inlet side, thereby returning to the original free state. . Thereafter, the ring-shaped rotating body 2 rotates 45 degrees in the same direction from the stopped state by repeating the operations of the free state, pressing by opening the door A, stopping and re-pressing, and the pin opening X is in the open state. The closed state is repeated.
[0024]
According to the flooring per door 10 in the first embodiment, since the spring biasing to the locking body (pin) is performed in a horizontal plane, the main body shape can be made flat, and the ring-shaped rotating body has a predetermined angle. Since the pin opening is directly opened or closed by turning, it is possible to reliably hold the door open and release the door only by opening and closing the door.

FIGS. 17 to 19 are perspective views of the front side member of the short shaft frame and the rotating plate that opens and closes the pin opening X.
[0026]
In the second embodiment, the main difference between the second embodiment and the first embodiment is that the ring-like rotating body is placed in the short-axis frame in the door-contact main body. The point that the ring groove is loosely fitted, so-called inscribed type, and the pin opening X is opened and closed indirectly by tilting or raising the rotating plate by rotating the ring-shaped rotating body. is there. That is, the door stop main body 100a has a bottom plate 600 fixed to the floor surface, a mechanism for rotating the ring-shaped rotating body 300, that is, a flat short shaft frame 200 that houses the arm member 500 and the torsion spring 510. The rotating plate 400 is attached to the short shaft frame 200 so as to be freely rotatable, and the pin opening X is opened and closed by standing or standing, and the lid member 700.
[0027]
The bottom plate 600 is a circular thin plate and includes three screw holes 601, three small screw holes 602, and an engagement plate wall member 603 having a plate-like spring portion 604 that stands on a part of the peripheral end surface. The screw hole 601 is a hole through which the screw 110 reaching the floor surface through the short shaft frame body 200 and the bottom plate 600 is passed, and the small screw hole 602 is a hole through which the small screw 900 fixing the short shaft frame body 200 and the bottom plate 600 is passed. is there.
[0028]
The short-axis frame 200 is a flat conical frame having two openings 202 and 204 divided by a thin substrate 203 having a step located at the center, and has a predetermined strength and three screw holes 215. The top plate 201, the ring groove 217 loosely fitted to the ring-shaped rotating body 300 which is eccentrically provided on the back surface, the boss 207 to which the torsion spring is attached, and the engagement plate wall material 603 attached to the bottom plate. A groove 219 to be fitted is provided. The deep groove portion on the front side of the step-shaped ring groove 217 is a groove in which the mountain-shaped protrusion 301 of the ring-shaped rotating body 300 to be loosely fitted is loosely fitted. The bottom plate 216 and the opening 202 of the thin substrate 203 form a substantially fan-shaped rotation space in which the arm member 500 rotates by a predetermined angle in the horizontal direction. A cylindrical body 208 having a hole is attached. The opening 204 is an opening that is slightly larger than the rectangular rotating plate 400, and a shaft hole 206 into which the rotating shaft 402 is fitted is provided on the back surface of the short shaft frame 200 on both sides of the opening 204. In addition, the periphery of the opening 204 has a thin plate opening plate 205 in the front and a thin plate substrate 203 in the rear, and the surface portion forms the same horizontal surface so that the pins can smoothly enter and exit when the rotating plate 400 is fitted and laid down. To do. Since the operation of the arm member 500 that falls or stands up the rotating plate 400 that opens and closes the pin opening X is within the horizontal plane, the short shaft frame 200 can be shortened in the height direction. For this reason, even if the ring-shaped rotating body 300 is fitted, it can be flattened, and a door-stop main body having excellent design can be obtained.
[0029]
The arm member 500 includes a screw hole 504 that fits into a cylindrical body 208 attached to the short shaft frame body 200, an arm main body portion 501, and a semi-cylindrical contact portion 502 that stands on the central side surface of the arm main body portion. The tip engagement piece 503 is provided with elasticity by deep cutting. Further, the back surface of the arm member 500 has a stepped shape, and when the arm member 500 is fitted to the cylindrical body 208, along the stepped shape of the bottom plate 216 formed by the opening 202 of the short shaft frame body 200 and the thin substrate 203. It is placed horizontally.
[0030]
The ring-shaped rotating body 300 is loosely fitted so as to be embedded in the ring groove 217 having a step formed on the back surface of the short shaft frame 200 and is freely rotatable, and is arranged on the surface at equal intervals of 60 degrees. And 12 saw-tooth-like engagement grooves 302 are formed at equal pitches, that is, at intervals of 30 degrees, and 12 engagements are formed on the outer peripheral surface. A recess 304 is formed (see FIG. 15). The lid member 700 is a cap having an opening 702 having substantially the same shape as the pin opening of the short shaft frame body 200, and the engagement protrusion 701 on the front side of the side surface and the fitting groove 218 of the short shaft frame body 200 are detachable. Mating. The rotation plate 400 has a substantially rectangular shape, and has a rotation shaft 402 on both sides of one end, and a notch 403 slightly larger than the width dimension of the ring-shaped rotation body 300 on the back surface.
[0031]
In order to assemble the door stop main body 100a made of such components, for example, the rotating plate 400 is inserted from below the opening 204, the rotating shaft 402 is fitted into the shaft hole 206 of the short shaft frame body 200, and then the short shaft The ring-shaped rotating body 300 is fitted into the ring groove 217 of the frame body 200. Both the ring-shaped rotating body 300 and the rotating plate 400 will drop downward unless supported by hand. For this reason, after attaching these two members to the short shaft frame body 200, it is preferable to attach the bottom plate 600. The bottom plate 600 aligns each screw hole with the screw hole of the short shaft frame body 200 and fits the engagement plate wall member 603 into the groove 219. Further, the shaft hole 504 of the arm member 500 is rotatably fitted in the cylindrical body 208 and is screwed with a screw 800 to prevent the drop. The distal end locking piece 503 of the arm member 500 is engaged with the engaging groove 302 of the ring-shaped rotating body 300. Next, the torsion spring 510 is engaged with the boss 207, and the arm member 500 is arranged to be biased toward the pin opening side. Next, the short shaft frame 200 and the bottom plate 600 are passed through the three screws 110 and fixed to the floor surface. Finally, the lid 700 is attached to complete the assembly. This state is a standby state, the arm member 500 is in contact with the pin opening X side of the bottom plate 216 of the short shaft frame body 200, and the rotation plate 400 is in a lying state, so that the pin opening X Is vacant in the lateral direction (FIG. 20A).
[0032]
Next, the operating mechanism of the floor door 100a will be described with reference to FIGS. 17 to 19, the operation mechanism from the strike pin restrained state to the open state will be described. FIGS. 17 and 20C are 100a per flooring door in a strike pin restraint state. In this state, the door A is in the open state, the strike pin 101 is in the pin restraining position Y, and the mountain-shaped protrusion 301 of the ring-shaped rotating body 300 is positioned in the pin opening X, so that the rotating plate 400 is inclined obliquely. The opening is closed (FIGS. 17B and 20C). Next, to release the restraint of the strike pin 101, the arm member 500 is pushed backward against the spring bias by the re-pressing force of the pin 101 (FIG. 20D). Thereby, the arm member 500 rotates around the boss 208. Since the distal end engaging piece 503 of the arm member 500 is engaged with the engaging groove 302 of the ring-shaped rotating body 300, the ring-shaped rotating body 300 also rotates (FIG. 18). In this example, the rotation range of the arm member 500 is restricted by the sector shape of the substrate 216 of the short shaft frame 200, and stops when the ring-shaped rotation body 300 rotates 30 degrees. Therefore, the pin opening X has a flat portion without the ring-shaped protrusion of the ring-shaped rotating body 300, so that the rotating plate 400 has no support and falls down due to gravity. For this reason, since the pin opening X is vacant in the lateral direction, the strike pin 101 is released from the restrained state. At this time, when the door A is no longer pressed, the arm member 500 is returned to the original position by the urging of the torsion spring 510, and the tip engagement piece 503 engages with the rear engagement groove 302. Further, since the spring piece 604 having a ratchet function is engaged with the engagement groove 304, the ring-shaped rotating body 300 is not rotated in synchronization with the return of the arm member 500. Thereby, the door stop main-body part 100a will be in an original standby state (FIG. 19, FIG. 20 (A)). Thereafter, as in the first embodiment, the operations of stopping (pin restraint), re-pressing, free state, and pressing by opening the door A are repeated, and the ring-shaped rotating body 300 is stopped from the stopped state. Since the pin-shaped protrusion 301 comes and disappears in the pin opening X every 30 degrees in the same direction, the rotating body 400 repeatedly falls and tilts up, and as a result, the pin opening X is in the open state. The closed state is repeated. In the door stop main body portion 100a of this example, the engagement groove 302 and the arrangement pitch 301 of the mountain-shaped protrusions that are engaged with the arm-shaped member 500 of the ring-shaped rotating body 300 are not limited to the above-described 30 degrees, and are appropriately determined. The
[0033]
According to the flooring door contact according to the second embodiment, since the spring biasing to the locking body (pin) is performed in the horizontal plane, the main body shape can be flattened, and the built-in ring-shaped rotating body is predetermined. Since the pin opening is indirectly opened or closed by rotating the angle, it is possible to reliably hold the door open and release the door only by opening and closing the door.
[0034]
【The invention's effect】
According to the present invention, the main body shape is flattened by performing spring urging on the locking body (pin) in a horizontal plane, and the door can be securely held and opened only by opening and closing the door. Release can be performed.
