【０００１】
【発明の属する技術分野】
本発明は、車庫等の出入口に用いて好適な跳ね上げ式門扉に関する。
【０００２】
【発明が解決しようとする課題】
この種の門扉としては、特開平７−２７９５６４号公報等に記載のような、支柱と、一端で支柱に回動自在に支持されたアーム部材と、アーム部材の他端部に取付けられた扉と、この扉及びアーム部材の自重に抗して扉の跳ね上げ方向に弾性力をアーム部材に付与するコイルばね及びガススプリングからなる弾性力付与手段とを具備したものが知られている。
【０００３】
上記公報記載の類いの跳ね上げ式門扉は、コイルばねとガススプリングとによって、アーム部材及び扉のそれぞれの自重に抗するような弾性的な跳ね上げ力をアーム部材に付与して、手動による開扉を容易にしているが、開扉に際して扉にかける手動力が大きい場合には、弾性的な跳ね上げ力に加えてこの大きな手動力がアーム部材に加わるため、アーム部材が勢いよく回動されることとなり、アーム部材がストッパ等に激突して、不快な騒音を発し、扉の寿命を縮めたりする虞がある。また、手動による閉扉の際にも、同じく大きな手動力を扉にかけると、同様な不都合が生じる虞がある。
【０００４】
跳ね上げ式門扉は、温度変化の激しい戸外に通常配されるため、ガススプリングもまた温度変化の激しい環境に晒されることになり、ガススプリングの弾性力の温度依存性により、上記の不都合が季節により極端に生じる虞がある上に、季節により中途開扉を維持することが困難な場合も生じ得る。
【０００５】
ガススプリングを用いないで、弾性的な跳ね上げ力（扉の上げ方向の力）をコイルばねのみでアーム部材に付与すると共に扉の下げ方向に抗する抵抗力を粘性ダンパでアーム部材に付与するようにした跳ね上げ式門扉も提案されている。
【０００６】
跳ね上げ式門扉では、扉を跳ね上げ方向に回動するにしたがって扉の自重による扉の下げ方向への回動モーメントが減少する上に、通常、扉で開閉すべき開口部の開口横幅の長短によって、扉の高さ方向の構成部材を変更する必要はあまりないが、扉の横桟等の扉の横方向の構成部材をそれに応じて長くしたり短くしたりするために、扉の重量に加えて扉の重心も種々異なるようになる結果、扉を跳ね上げ方向に回動することによる回動モーメントの減少の仕方が扉の横幅の長短によって種々の態様となり、上述のように弾性的な跳ね上げ力をコイルばねのみで扉の下げ方向に抗する抵抗力を粘性ダンパで夫々アーム部材に付与するようにした跳ね上げ式門扉では、扉の横幅の長短に応じた弾性力をもったコイルばねを用いないで、例えば横幅の最も長い扉にあった弾性力を有したコイルばねを標準品として用いると、それよりも横幅の短い扉ではその跳ね上げ方向への手動回動に際して、扉にかける手動力が大きい場合には、弾性的な跳ね上げ力に加えてこの大きな手動力がアーム部材に加わるため、アーム部材が勢いよく回動されることとなって全開位置でストッパに激突して騒音を発したりしてして不快な動作を行うことになり、また、途中から特に手動力を与えなくても全開位置まで扉が跳ね上げられて途中で扉を停止させることが困難となる。
【０００７】
またこの種の跳ね上げ式門扉では、扉の開閉時に扉自体が前方にせり出し、このせり出し分を考慮して扉の開閉を行わないと思わぬ事故を招く虞がある上に、せり出しにより扉の開閉が邪魔されて扉の開閉操作性が極めて悪く、加えて、せり出し分を考慮して設置すると扉内の利用空間が狭くなるという問題を有している。
【０００８】
本発明は、前記諸点に鑑みてなされたものであって、その目的とするところは、温度依存性をなくし得る結果、季節に拘わらず、扉にかける手動力が通常より大きい場合においても、アーム手段及び扉に急激な回動を生じさせることなしに、スムーズに扉を開閉することができ、アーム手段の激突による不快音の発生をなくし得、寿命の長いしかも中途開扉をも確実に維持できる跳ね上げ式門扉を提供することにある。
【０００９】
また本発明の他の目的とするところは、扉の前方へのせり出しをできるだけなくし得て、せり出しに起因する事故等の不都合をなくし、扉内の利用空間を広くできる跳ね上げ式門扉を提供することにある。
【００１０】
【課題を解決するための手段】
本発明の第一の態様の跳ね上げ式門扉は、支柱と、この支柱に一端部で鉛直面内で回動自在に支持されたアーム手段と、このアーム手段の他端部に取付けられた扉と、この扉及びアーム手段の自重に抗して扉の跳ね上げ方向に弾性力をアーム手段に付与する弾性力付与手段と、扉の上げ下げ両方向のアーム手段の回動に抗する粘性剪断抵抗力をアーム手段に付与する粘性剪断抵抗力付与手段とを具備しており、弾性力付与手段はコイルばねを具備しており、ここで、実質的にこのコイルばねにより扉の跳ね上げ方向への弾性力をアーム手段に付与するようになっている。
【００１１】
第一の態様の跳ね上げ式門扉によれば、扉の自重に基づくアーム手段の下げ方向の回動モーメントとコイルばねの弾性力に基づく扉の上げ方向の回動モーメントとの差異が扉の横幅の長短による重量及び重心の相違により大幅に異なっても、この差異の相違を、扉の上げ下げ両方向においてアーム手段に付与される粘性剪断抵抗力付与手段の粘性剪断抵抗力によって無視できるようにし得、而して、種々の横幅をもった扉の中途開扉をも確実に維持できる上に、扉の上げ下げ両方向においてアーム手段及び扉の急激な回動を生じさせることなしに、スムーズに扉を開閉することができ、扉及びアーム手段のストッパ等への激突による不快音の発生をなくし得て寿命を長くできる上に、ガススプリングに比較して極めて少ないが多少存在する縮みコイルばねの温度依存性に基づく弾性力の変化による影響をなくし得、しかも、実質的にコイルばねにより扉の跳ね上げ方向への弾性力をアーム手段に付与するようになっているために、温度依存性をなくし得る結果、季節に拘わらず上記の効果を確実に生じさせることができる。
【００１２】
弾性力付与手段は、好ましい例では本発明の第二の態様の跳ね上げ式門扉のように、扉の跳ね上げ方向にアーム手段を回動させる弾性力を発生するものとしてコイルばねのみを具備している。
【００１３】
第一及び第二の態様の跳ね上げ式門扉のいずれも、実質的にコイルばねにより扉の跳ね上げ方向にアーム手段を回動させる縮み弾性力を発生するようにしているために、ガススプリングに比較して温度依存性をなくし得る結果、季節に拘わらず、扉にかける手動力が通常より大きい場合においても、アーム手段及び扉に急激な回動を生じさせることなしに、スムーズに扉を開閉することができ、アーム手段の激突による不快音の発生をなくし得、寿命を長くできて中途開扉をも確実に維持できる。
【００１４】
本発明の第三の態様の跳ね上げ式門扉では、第一又は第二の態様の跳ね上げ式門扉において、支柱に一端部で鉛直面内で回動自在に支持されていると共に他端部に扉が鉛直面内で回動自在に取付けられた主アーム部材と、この主アーム部材における一端部と他端部との間に一端部で鉛直面内で回動自在に連結された連結部材と、扉に一端部で鉛直面内で回動自在に連結されていると共に連結部材が鉛直面内で回動自在に連結された補助アーム部材と、連結部材の他端部と補助アーム部材の他端部とのうちの少なくとも一方の他端部を支柱に鉛直面内で回動自在であって鉛直方向に可動に連結すると共に当該一方の他端部の鉛直方向の移動を案内する連結案内手段とを具備している。
【００１５】
第三の態様の跳ね上げ式門扉では、連結部材と補助アーム部材とが互いに鉛直面内で回動自在に連結されて、連結案内手段を介して連結部材の他端部と補助アーム部材の他端部とのうちの少なくとも一方の他端部が支柱に鉛直面内で回動自在であって鉛直方向に可動に連結されているので、例えば完全閉鎖位置からの扉の開放において主アーム部材が回動されると、それに連れて連結部材が回動されながら主アーム部材に引きずられる結果、補助アーム部材全体が支柱側に若干引き寄せられて、扉の下端のせり出しをなくす方向に扉が回動され、而して、扉の前方へのせり出しをできるだけなくし得て、せり出しに起因する事故、操作性の劣化等の不都合をなくし、扉内の利用空間を広くできる。
【００１６】
連結案内手段は、本発明の第四の態様の跳ね上げ式門扉のように、連結部材の他端部を支柱に鉛直面内で回動自在であって鉛直方向に可動に連結していても、本発明の第五の態様の跳ね上げ式門扉のように、補助アーム部材の他端部を支柱に鉛直面内で回動自在であって鉛直方向に可動に連結していても、本発明の第六の態様の跳ね上げ式門扉のように、連結部材と補助アーム部材とがそれらの他端部同士で互いに鉛直面内で回動自在に連結されている状態で、連結部材の他端部と補助アーム部材の他端部とを支柱に鉛直面内で回動自在であって鉛直方向に可動に連結していてもよい。
【００１７】
第四の態様の跳ね上げ式門扉では、補助アーム部材は、その他端部で連結部材における一端部と他端部との間又は連結部材の他端部の外側に鉛直面内で回動自在に連結されてもよく、第五の態様の跳ね上げ式門扉では、連結部材は、その他端部で補助アーム部材における一端部と他端部との間又は補助アーム部材の他端部の外側に鉛直面内で回動自在に連結されてもよく、第六の態様の跳ね上げ式門扉では、連結部材の他端部と補助アーム部材の他端部とが共通軸をもって互いに鉛直面内で回動自在に連結されていてもよい。
【００１８】
本発明の第七の態様の跳ね上げ式門扉では、第三から第六のいずれかの態様の跳ね上げ式門扉において、連結案内手段は、支柱に設けられた鉛直方向に伸びた案内通路を具備しており、案内通路は、連結部材の他端部と補助アーム部材の他端部とのうちの少なくとも一方の他端部の鉛直方向の移動を案内するようになっている。
【００１９】
案内通路としては、支柱に設けられたスリット、溝、突条又はレールであってよく、斯かる案内通路の場合、連結案内手段は、第八の態様の跳ね上げ式門扉のように、連結部材の他端部と補助アーム部材の他端部とのうちの少なくとも一方の他端部に設けられていると共に鉛直方向に可動となるように案内通路に嵌合されたスライダ又は回転自在なローラを具備しているとよい。
【００２０】
本発明の第三から第八のいずれかの態様の跳ね上げ式門扉において、好ましくは、その第九の態様の跳ね上げ式門扉のように、扉の完全閉鎖位置で、支柱に対する主アーム部材の鉛直面内での回動軸心と主アーム部材に対する連結部材の鉛直面内での回動軸心とを結ぶ直線は、支柱に対する主アーム部材の鉛直面内での回動軸心を通る水平面に対して俯角をなして伸びており、扉に対する補助アーム部材の鉛直面内での回動軸心と連結部材に対する補助アーム部材の鉛直面内での回動軸心とを結ぶ直線は、連結部材に対する補助アーム部材の鉛直面内での回動軸心を通る水平面に対して俯角をなして伸びており、主アーム部材に対する連結部材の鉛直面内での回動軸心と連結部材に対する補助アーム部材の鉛直面内での回動軸心とを結ぶ直線は、連結部材に対する補助アーム部材の鉛直面内での回動軸心を通る水平面に対して仰角をなして伸びている。
【００２１】
また第三から第九のいずれかの態様の本発明の跳ね上げ式門扉では、好ましくは、その第十の態様の跳ね上げ式門扉のように、主アーム部材と補助アーム部材とは、側面から見て、扉の完全閉鎖位置ではほぼ互いに平行に伸び、扉の完全開放位置では、互いに交差して伸びるようになっている。
【００２２】
更に第一から第十のいずれかの態様の本発明の跳ね上げ式門扉では、好ましくは、その第十一の態様の跳ね上げ式門扉のように、完全閉鎖位置からほぼ１５°までの扉の開放においては、扉の下端は、支柱側に近接するようになっている。
【００２３】
本発明において弾性力付与手段は、第十二の態様の跳ね上げ式門扉のように、好ましくは、アーム手段の回動と共に回動されるように、アーム手段に連結された回転自在なカム板と、このカム板に一端が連結されていると共に、カム板のカム縁に当接して曲げ案内される可撓性部材とを具備しており、コイルばねの一端は可撓性部材の他端部に、その他端部は支柱に夫々連結されている。
【００２４】
第十二の態様の跳ね上げ式門扉によれば、カム板のカム縁に当接して曲げ案内される可撓性部材の他端部にコイルばねの一端が連結されているために、コイルばねの弾性力に基づいてカム板に付与する回転モーメントをカム板の回転位置に拘わらず所望にできる結果、アーム手段の回動位置に最適な弾性力をアーム手段に付与できる。
【００２５】
本発明の第十三の態様の跳ね上げ式門扉では、カム板は、その外縁部に円弧状に配列された歯列を有しており、粘性剪断抵抗力付与手段は、カム板の歯列に噛合う歯車と、この歯車と共に回転される回転体と、回転体に対して固定された固定体と、回転体と固定体との間に介在された粘性体とを具備している。
【００２６】
第十三の態様の跳ね上げ式門扉によれば、弾性力付与手段と粘性剪断抵抗力付与手段とを近接して配置できる上に、部品点数を削減できる。
【００２７】
次に本発明の実施の形態を、図に示す好ましい例に基づいて更に詳細に説明する。なお、本発明はこれら例に何等限定されないのである。
【００２８】
【発明の実施の形態】
図１から図９において、本例の跳ね上げ式門扉１は、立設された一対の中空の角形の支柱２及び３と、支柱２及び３に一端部で鉛直面内でＡ及びＢ方向に回動自在に支持されたアーム手段８１及び８２と、アーム手段８１及び８２の他端部に取付けられた扉１３と、扉１３の上枠２７に並置されていると共に一端部がアーム手段８１の主アーム部材８の他端部１０に他端部がアーム手段８２の主アーム部材９の他端部１１に夫々固着された補強用の横桟３０と、扉１３及びアーム手段８１及び８２の自重に基づく扉１３の下げ方向、即ちＢ方向のアーム手段８１及び８２の回動に抗する扉１３の跳ね上げ方向、即ちＡ方向の回動力である弾性力をアーム手段８１及び８２に付与するように支柱２及び３に内蔵された弾性力付与手段３１及び３２と、扉１３の上げ下げ方向、即ちＡ及びＢ方向の両方向にアーム手段８１及び８２の回動に抗する粘性剪断抵抗力をアーム手段８１及び８２に付与するように支柱２及び３に内蔵された粘性剪断抵抗力付与手段８３及び８４とを具備している。
【００２９】
アーム手段８１及び８２は、支柱２及び３に一端部４及び５で軸部材６及び７を介して鉛直面内でＡ及びＢ方向に回動自在に支持されていると共に他端部１０及び１１に軸部材１２（支柱３側は図示せず）を介して鉛直面内でＣ及びＤ方向に回動自在に扉１３の縦枠４１及び４２が取付けられた角材からなる主アーム部材８及び９と、主アーム部材８及び９における一端部４及び５と他端部１０及び１１との間に一端部１４（支柱３側は図示せず）で軸部材１５（支柱３側は図示せず）を介して鉛直面内でＥ及びＦ方向に回動自在に連結されている角材からなる連結部材１６及び１７と、扉１３の縦枠４１及び４２に一端部１８及び１９で軸部材２０（支柱３側は図示せず）を介して鉛直面内でＧ及びＨ方向に回動自在に連結されていると共に連結部材１６及び１７が軸部材３５（支柱３側は図示せず）を介して鉛直面内でＪ及びＫ方向に回動自在に連結された角材からなる補助アーム部材２１及び２２と、連結部材１６及び１７の他端部２３（支柱３側は図示せず）と補助アーム部材２１及び２２の他端部２４及び２５とのうちの少なくとも一方の他端部、本例では両他端部２３並びに２４及び２５を支柱２及び３に鉛直面内でＪ及びＫ方向に回動自在であって鉛直方向Ｖに可動に連結すると共に当該他端部２３並びに２４及び２５の鉛直方向Ｖの移動を案内する連結案内手段２６（支柱３側は図示せず）とを具備している。
【００３０】
扉１３は、上枠２７並びに上枠２７に固着された縦枠４１及び４２に加えて、縦枠４１及び４２に固着された下枠４４と、上枠２７及び下枠４４を橋絡した目隠し用の複数の縦格子４３と、縦枠４１及び４２の夫々の下面に取付けられたストッパ４５及び４６と、縦枠４１及び４２に固着されたブラケット４７（支柱３側は図示せず）とを具備している。扉１３としては、縦格子４３を具備したものに限定されず、横格子を取付けたもの等その他のものであってもよい。ブラケット４７に軸部材１２及び２０が取付けられている。
【００３１】
本例では、支柱２側と支柱３側とは、互いに同様に構成されているので、以下、主に支柱２側について説明する。
【００３２】
連結部材１６と補助アーム部材２１とは、その夫々の他端部２３及び２４同士で軸部材３５を介して互いに鉛直面内でＪ及びＫ方向に回動自在に連結されている。
【００３３】
連結案内手段２６は、支柱２に固着されていると共に鉛直方向Ｖに伸びた断面Ｕ字状の案内部材５１と、軸部材３５に回転自在に取付けられていると共に案内部材５１により規定されて鉛直方向Ｖに伸びた案内通路５２に嵌合されたローラ５３と、ローラ５３の一定以上の下降を禁止するストッパ５４とを具備しており、こうして本例の連結案内手段２６は、支柱２に設けられた鉛直方向Ｖに伸びた案内通路５２と、連結部材１６の他端部２３と補助アーム部材２１の他端部２４とのうちの少なくとも一方の他端部、本例では両他端部２３及び２４に軸部材３５を介して設けられていると共に鉛直方向Ｖに可動となるように案内通路５２に嵌合された回転自在なローラ５３とを具備して、而して、両他端部２３及び２４を支柱２に鉛直面内でＪ及びＫ方向に回動自在であって鉛直方向Ｖに可動に連結すると共に両他端部２３及び２４の鉛直方向Ｖの移動を案内するようになっている。
【００３４】
本例では、ストッパ４５が地面５５に当接して、扉１３が地面５５に直立した扉１３の完全閉鎖位置（図１及び図２に示す位置）で、支柱２に対する主アーム部材８の鉛直面内でのＡ及びＢ方向の回動軸心６１（軸部材６の軸心）と主アーム部材８に対する連結部材１６の鉛直面内でのＥ及びＦ方向の回動軸心６２（軸部材１５の軸心）とを結ぶ直線６３は、回動軸心６１を通る水平面に対して俯角αをなして伸びており、扉１３に対する補助アーム部材２１の鉛直面内でのＧ及びＨ方向の回動軸心６４（軸部材２０の軸心）と連結部材１６に対する補助アーム部材２１の鉛直面内でのＪ及びＫ方向の回動軸心６５（軸部材３５の軸心）とを結ぶ直線６６は、回動軸心６５を通る水平面に対して俯角βをなして伸びており、回動軸心６２と回動軸心６５とを結ぶ直線６７は、回動軸心６５を通る水平面に対して仰角γをなして伸びており、扉１３に対する主アーム部材８の鉛直面内でのＣ及びＤ方向の回動軸心６８（軸部材１２の軸心）と回動軸心６１との間の距離Ｌ１は、回動軸心６４と回動軸心６５との間の距離Ｌ２よりも短く、主アーム部材８と補助アーム部材２１とは、側面から見て、ほぼ互いに平行に伸びるようになっており、完全閉鎖位置（図１及び図２に示す位置）からほぼ１５°までの主アーム部材８のＡ方向の回動による扉１３の開放においては、扉１３の下端７１は、支柱２側に近接するようになっており、扉１３の完全開放位置（図１０及び図１１参照）では、主アーム部材８と補助アーム部材２１とは互いに交差して伸びるようになっている。
【００３５】
支柱２に内蔵された弾性力付与手段３１は、基板１０４を貫通すると共に支柱２にＡ及びＢ方向に回転自在に支持された軸部材６に固着されて、これによりアーム手段８１の回動と共にＡ及びＢ方向に回転されるようにアーム手段８１に連結された回転自在なカム板８５と、カム板８５にピン８６を介して一端部８７が連結されていると共に中間部８８がカム板８５のカム縁８９に当接して曲げ案内された可撓性部材としてのローラチェーン９０と、ローラチェーン９０の他端部９１にピン９２を介して回動自在に連結された連結具９３と、一端部９４が連結具９３の孔９５に引っ掛けられたコイルばね９６と、コイルばね９６の他端部９７が孔９８に引っ掛けられていると共にピン９９を介してブラケット１００に回動自在に連結された連結具１０１とを具備しており、ブラケット１００は、支柱２に固着されており、こうして、コイルばね９６の一端部９４は、連結具９３を介してローラチェーン９０の他端部９１に、コイルばね９６の他端部９７は、ブラケット１００及び連結具１０１を介して支柱２に連結されている。
【００３６】
基板１０４は、支柱２内において支柱２にねじ等により固着されており、カム板８５は、回動軸心６１を中心とした円孔状のスリット１０２と、回動軸心６１を中心とした円孔状の外縁部に形成されて円弧状に配列された歯列１０３とを有しており、スリット１０２には、基板１０４に一端部が固着されたストッパ部材１０５の他端部が配されており、ストッパ部材１０５の他端部には、回転自在にローラ１０６が装着されており、カム板８５は、スリット１０２のＡ及びＢ方向の端部でローラ１０６に当接することによりＡ及びＢ方向のそれ以上の回転ができないようになって、扉１３の完全開扉及び完全閉扉を規定するようになっている。カム縁８９は、主アーム部材８の回動軸心（軸部材６及びカム板８５の回転中心）６１を中心とした円弧縁１０７と、好ましくは円弧縁１０７に連続した直線縁１０８とを具備しているとよい。
【００３７】
弾性力付与手段３１は、扉１３の跳ね上げ方向（Ａ方向）にアーム手段８１を回動させる縮み弾性力を発生するものとしてコイルばね９６のみを具備しており、而して、実質的にコイルばね９６により扉１３の跳ね上げ方向への縮み弾性力をアーム手段８１に付与するようになっている。
【００３８】
粘性剪断抵抗力付与手段８３は、内面に同心の環状の複数の突起１１５を一体的に有していると共に基板１０４にねじ等により固着された固定体としてのハウジング１１６と、ハウジング１１６内に、ハウジング１１６に対して軸心１１７を中心として相対的にＬ及びＭ方向の両方向に回転自在に収容されて、ハウジング１１６の複数の突起１１５と協同してハウジング１１６内に環状及び円筒状の隙間１１８を形成する同心の環状の複数の突起１１９を一体的に有した隙間形成部材１２０と、隙間形成部材１２０とハウジング１１６との間の環状及び円筒状の隙間１１８に充填されて隙間形成部材１２０とハウジング１１６との間に介在された粘性体１２１と、隙間形成部材１２０が固着されていると共にハウジング１１６に軸心１１７を中心として回転自在に支持された軸部材１２２と、軸部材１２２に固着されていると共にカム板８５の歯列１０３に噛合う歯車１２３とを具備している。
【００３９】
カム板８５の歯列１０３に噛合う歯車１２３と、歯車１２３と共に回転される軸部材１２２及び隙間形成部材１２０からなる回転体１２４と、回転体１２４に対して固定された固定体としてのハウジング１１６と、回転体１２４の隙間形成部材１２０とハウジング１１６との間に介在された粘性体１２１とを具備している粘性剪断抵抗力付与手段８３は、ハウジング１１６と隙間形成部材１２０との軸心１１７を中心としたＬ及びＭ方向の相対的な回転により粘性体１２１に粘性剪断抵抗力を発生させるようになっている。
【００４０】
弾性力付与手段３２及び粘性剪断抵抗力付与手段８４も支柱３に内蔵されて弾性力付与手段３１及び粘性剪断抵抗力付与手段８３と同様に構成されている。
【００４１】
以上の跳ね上げ式門扉１では、完全閉鎖位置では図１及び図２に示すようにストッパ４５が地面５５に当接して、しかも、扉１３が地面５５にほぼ直立した状態になる。この状態で手動により扉１３が持ち上げられることにより軸部材６を介して主アーム部材８がＡ方向に回動されると、主アーム部材８に軸部材１５を介して一端部１４が連結された連結部材１６は、主アーム部材８に対してＦ方向に回動されながら主アーム部材８に引きずられる結果、連結部材１６の他端部２４は、ローラ５３の回転を介して案内通路５２に案内されて上昇され、この上昇で補助アーム部材２１は全体として支柱２側に少し引っ張られ、この引っ張りにより扉１３は主アーム部材８の他端部１０に対してＤ方向に回動され、従って、扉１３は、その下端７１が図１１の軌跡ａ−ｂ−ｃで示すように前方にせり出すことなしに、地面５５にほぼ直立した状態をもって上昇し、完全閉鎖位置（図１及び図２に示す位置）からほぼ１５°まで主アーム部材８がＡ方向に回動された後は、主アーム部材８のＡ方向の回動と共に扉１３は、その下端７１が若干前方にせり出しつつ図１１に示す軌跡ｃ−ｄ−ｅ−ｆをもって上昇する。なお、下端７１が軌跡ｅからｆをもって扉１３が上昇する間は、主アーム部材８と補助アーム部材２１とは互いに交差して伸びるようになっている。
【００４２】
下端７１が軌跡ｆの位置となる扉１３の完全開放状態では、ローラ５３がストッパ５４に当接してローラ５３のそれ以上の下降が禁止されるか、又はローラ１０６が図１０に示すようにスリット１０２のＢ方向の端部でカム板８５に当接してローラ１０６のそれ以上の移動が禁止される結果、主アーム部材８の鉛直面内でのＡ方向のそれ以上の回動ができなくなる。
【００４３】
扉１３を完全開放状態から完全閉鎖状態にするには、手動により扉１３を引き下げることにより軸部材６を介して主アーム部材８をＢ方向に回動すればよい。扉１３の完全閉鎖状態への移行でも、扉１３は、その下端７１が図１１に示す軌跡ｆ−ｅ−ｄ−ｃ−ｂ−ａをもって下降する。
【００４４】
また以上の跳ね上げ式門扉１では、手動により扉１３が持ち上げられると、主アーム部材８がＡ方向に回動され、これと共にカム板８５も図１０に示すように同様に回転される。この回転において、コイルばね９６の引っ張り弾性力により、扉１３等の自重が適宜打ち消されて手動開扉が困難なく行えるようになっている。一方、手動による扉１３への少しの下降力の付加により、主アーム部材８がＢ方向に回動され、これと共にカム板８５も同様に回転される結果、コイルばね９６の引っ張り弾性力の作用で多少の反力をもって閉扉することができる。
【００４５】
更に跳ね上げ式門扉１では、開扉において、主アーム部材８のＡ方向の回動は、カム板８５の歯列１０３を介して歯車１２３に伝達されて、ハウジング１１６に対して隙間形成部材１２０をＬ方向に回転させてハウジング１１６と隙間形成部材１２０との間に相対回転を生じさせ、これにより粘性体１２１が粘性剪断されて、この粘性剪断に相当して粘性剪断抵抗力が回転体１２４を介して歯車１２３に現出して、この粘性剪断抵抗力は、主アーム部材８のＡ方向の回動に制動を加える。
【００４６】

以上の跳ね上げ式門扉１では、コイルばね９６のみにより扉１３の跳ね上げ方向にアーム手段８１を回動させる縮み弾性力を発生するようにしているために、ガススプリングに比較して温度依存性をなくし得る結果、季節に拘わらず、扉１３にかける手動力が通常より大きい場合においても、アーム手段８１及び扉１３に急激な回動を生じさせることなしに、スムーズに扉１３を開閉することができ、アーム手段８１の激突による不快音の発生をなくし得、寿命を長くでき、しかも、中途開扉をも確実に維持できる。
【００４８】
加えて、跳ね上げ式門扉１では、粘性剪断抵抗力によりアーム手段８１の扉１３の上げ下げ方向の回動が制動されるようになっているために、開扉及び閉扉に際して扉１３にかける手動力が通常より大きい場合においても、アーム手段８１及び扉１３に急激な回動を生じさせることなしに、スムーズに開扉及び閉扉することができ、扉１３の激突による不快音の発生をなくし得、寿命を長くできる上に、ガススプリングに比較して極めて少ないが多少存在するコイルばね９６の温度依存性に基づく弾性力の変化による影響をなくし得る。

BACKGROUND OF THE INVENTION
The present invention relates to a flip-up gate suitable for use in an entrance of a garage or the like.
[0002]
[Problems to be solved by the invention]
As this type of gate door, as described in Japanese Patent Application Laid-Open No. 7-279564, etc., a support, an arm member rotatably supported by the support at one end, and a door attached to the other end of the arm member In addition, there has been known one provided with an elastic force applying means including a coil spring and a gas spring for applying an elastic force to the arm member in the direction in which the door and the arm member are lifted against the dead weight of the door.
[0003]
The kind of flip-up type gate described in the above publication is applied manually by applying a spring-up force against the respective weights of the arm member and the door to the arm member by a coil spring and a gas spring. Although the door is easy to open, when the manual force applied to the door is large when the door is opened, this large manual force is applied to the arm member in addition to the elastic flip-up force, so the arm member pivots vigorously As a result, the arm member may collide with the stopper or the like, generating unpleasant noise and shortening the life of the door. In addition, when manually closing the door, if a large manual force is applied to the door, the same inconvenience may occur.
[0004]
Since the flip-up type gate is usually arranged outside the door where the temperature changes rapidly, the gas spring is also exposed to an environment where the temperature changes rapidly. In addition, there may be a case where it is difficult to maintain a halfway door depending on the season.
[0005]
Without using a gas spring, an elastic spring-up force (force in the direction of raising the door) is applied to the arm member only with a coil spring, and a resistance force against the door lowering direction is applied to the arm member with a viscous damper. A flip-up gate that has been made is also proposed.
[0006]
In a flip-up type gate, the turning moment in the door lowering direction due to the weight of the door decreases as the door rotates in the flipping direction, and the opening width of the opening that should normally be opened and closed by the door is longer or shorter. Depending on the weight of the door, it is not necessary to change the structural members in the height direction of the door. In addition, the center of gravity of the door is also different. As a result, the manner in which the turning moment is reduced by turning the door in the flip-up direction varies depending on the width of the door, and is elastic as described above. In a flip-up type gate that uses a viscous damper to apply a resistance force that resists the lifting force to the lowering direction of the door using only a coil spring, each coil has an elastic force corresponding to the width of the door. Without using a spring, for example If the coil spring with the elastic force that fits the longest door is used as a standard product, if the door with a shorter width is manually rotated in the flip-up direction, the manual force applied to the door is large. Since this large manual force is applied to the arm member in addition to the elastic flip-up force, the arm member is rotated vigorously, causing a collision with the stopper at the fully open position and generating noise. An unpleasant operation will be performed, and it will be difficult to stop the door in the middle because the door is flipped up to the fully open position without any manual force applied from the middle.
[0007]
In this type of flip-up type gate, the door itself protrudes forward when the door is opened and closed, and there is a risk of unexpected accidents if the door is not opened and closed in consideration of the protruding portion. Opening / closing operation is hindered, and the door opening / closing operability is extremely poor. In addition, there is a problem that the use space in the door becomes narrow when installed considering the protruding portion.
[0008]
The present invention has been made in view of the above-mentioned points, and its object is to eliminate the temperature dependence, and as a result, regardless of the season, even when the manual force applied to the door is larger than usual, the arm The doors can be opened and closed smoothly without causing sudden rotation of the means and the door, and the generation of unpleasant noise due to the collision of the arm means can be eliminated. The aim is to provide a flip-up gate that can be lifted.
[0009]
Another object of the present invention is to provide a flip-up type gate which can eliminate the inconvenience of the door as much as possible, eliminate inconvenience such as an accident caused by the protrusion, and widen the use space in the door. There is.
[0010]
[Means for Solving the Problems]
The flip-up type gate of the first aspect of the present invention includes a support, arm means supported by the support at one end so as to be rotatable in a vertical plane, and a door attached to the other end of the arm. And an elastic force applying means for applying an elastic force to the arm means in the direction of raising the door against the dead weight of the door and arm means, and a viscous shear resistance force against the rotation of the arm means in both directions of raising and lowering the door. Viscosity shear resistance force applying means for applying force to the arm means, and the elastic force applying means includes a coil spring. Here, the coil spring substantially elastically springs up in the direction in which the door is flipped up. A force is applied to the arm means.
[0011]
According to the flip-up type gate of the first aspect, the difference between the turning moment in the lowering direction of the arm means based on the weight of the door and the turning moment in the raising direction based on the elastic force of the coil spring is the width of the door. This difference in difference can be made negligible by the viscous shear resistance force of the viscous shear resistance applying means applied to the arm means in both directions of raising and lowering the door, even if significantly different due to the difference in weight and center of gravity due to the length of Thus, the doors with various widths can be kept open, and the doors can be opened and closed smoothly without causing the arm means or the doors to suddenly turn in both directions. It is possible to eliminate the generation of unpleasant noise due to the collision of the door and arm means with stoppers, etc., and to extend the service life. The influence of the change in the elastic force based on the temperature dependence of the coil spring can be eliminated, and the elastic force in the spring-up direction of the door is substantially applied to the arm means by the coil spring. As a result of eliminating the dependency, the above-described effect can be surely produced regardless of the season.
[0012]
In a preferred example, the elastic force applying means includes only a coil spring that generates an elastic force for rotating the arm means in the direction in which the door is flipped up, like the flip-up type gate of the second aspect of the present invention. ing.
[0013]
Since both of the flip-up type gates of the first and second aspects generate a contraction elastic force that substantially rotates the arm means in the door flip-up direction by the coil spring, As a result of eliminating temperature dependence, the door can be opened and closed smoothly without causing sudden rotation of the arm means and door, even when the manual force applied to the door is greater than usual, regardless of the season. Therefore, it is possible to eliminate the generation of unpleasant noise due to the collision of the arm means, to prolong the service life and to reliably maintain the halfway door.

Since the other end of at least one of the ends is pivotable in the vertical plane and is movably connected in the vertical direction, for example, the main arm member is opened when the door is opened from the fully closed position. When it is rotated, the connecting member is rotated along with it and dragged to the main arm member. As a result, the entire auxiliary arm member is slightly pulled toward the support column, and the door rotates in a direction that eliminates the protrusion of the lower end of the door. Thus, the protrusion of the door to the front can be eliminated as much as possible, and inconveniences such as an accident caused by the protrusion and deterioration of operability can be eliminated, and the use space in the door can be widened.

In the flip-up type gate 1 described above, the stopper 45 comes into contact with the ground 55 as shown in FIGS. 1 and 2 in the fully closed position, and the door 13 is almost upright on the ground 55. When the main arm member 8 is rotated in the A direction via the shaft member 6 by manually lifting the door 13 in this state, the one end portion 14 is connected to the main arm member 8 via the shaft member 15. As a result of the connecting member 16 being dragged by the main arm member 8 while being rotated in the F direction with respect to the main arm member 8, the other end 24 of the connecting member 16 is guided to the guide passage 52 through the rotation of the roller 53. As a result, the auxiliary arm member 21 is pulled slightly toward the support column 2 as a whole, and this pull causes the door 13 to rotate in the D direction with respect to the other end portion 10 of the main arm member 8. The lower end 71 of the door 13 rises in a state of being almost upright on the ground 55 without protruding forward as indicated by a trajectory ab-c in FIG. 11, and is in a fully closed position (shown in FIGS. 1 and 2). Almost from the position) After the main arm member 8 is rotated in the A direction up to 5 °, as the main arm member 8 rotates in the A direction, the lower end 71 of the door 13 protrudes slightly forward and the locus cd shown in FIG. Ascend with -ef. The main arm member 8 and the auxiliary arm member 21 extend so as to intersect with each other while the lower end 71 rises with the f from the locus e.
[0042]
In the fully open state of the door 13 where the lower end 71 is at the position of the locus f, the roller 53 abuts against the stopper 54 and further lowering of the roller 53 is prohibited, or the roller 106 is slit as shown in FIG. As a result of contact with the cam plate 85 at the end in the B direction of 102 and prohibiting further movement of the roller 106, further rotation in the A direction within the vertical plane of the main arm member 8 becomes impossible.
[0043]
In order to change the door 13 from the fully open state to the fully closed state, the main arm member 8 may be rotated in the B direction via the shaft member 6 by manually pulling down the door 13. Even when the door 13 is shifted to the fully closed state, the lower end 71 of the door 13 descends with a trajectory fedcba-a shown in FIG.
[0044]
In the flip-up type gate 1 described above, when the door 13 is manually lifted, the main arm member 8 is rotated in the A direction, and the cam plate 85 is also rotated in the same manner as shown in FIG. In this rotation, due to the tensile elastic force of the coil spring 96, the weight of the door 13 and the like is appropriately canceled, and the manual opening can be performed without difficulty. On the other hand, the main arm member 8 is rotated in the direction B by the addition of a slight downward force to the door 13 manually, and the cam plate 85 is also rotated in the same manner. As a result, the action of the tensile elastic force of the coil spring 96 is achieved. The door can be closed with some reaction force.
[0045]
Further, in the flip-up type gate 1, when the door is opened, the rotation of the main arm member 8 in the A direction is transmitted to the gear 123 via the tooth row 103 of the cam plate 85, and the gap forming member 120 is connected to the housing 116. Is rotated in the L direction to cause a relative rotation between the housing 116 and the gap forming member 120, whereby the viscous body 121 is viscous sheared, and the viscous shear resistance corresponding to the viscous shear is applied to the rotating body 124. The viscous shear resistance exerts braking on the rotation of the main arm member 8 in the A direction.
[0046]
On the other hand, in the flip-up type gate 1 in the closed state, when the door 13 is manually lowered from the fully opened door shown in FIG. 10, the main arm member 8 is rotated in the B direction, and the main arm member 8 is rotated in the B direction. As a result of rotating the gap forming member 120 of the rotating body 124 in the M direction via the cam plate 85, the tooth row 103, and the gear 123, a relative rotation occurs between the housing 116 and the gap forming member 120. 121 is viscous sheared, and a viscous shear resistance corresponding to this viscous shear appears on the gear 123 in the same manner as described above, and this viscous shear resistance brakes the rotation of the main arm member 8 in the B direction. Add.
[0047]
In the above-described flip-up type gate 1, since the contraction elastic force for rotating the arm means 81 in the direction of the door 13 is generated only by the coil spring 96, the temperature dependency is higher than that of the gas spring. As a result, regardless of the season, the door 13 can be opened and closed smoothly without causing sudden rotation of the arm means 81 and the door 13 even when the manual force applied to the door 13 is larger than usual. It is possible to eliminate the generation of unpleasant noise due to the collision of the arm means 81, to prolong the service life, and to reliably maintain the halfway door.
[0048]
In addition, in the flip-up type gate 1, since the rotation of the door 13 of the arm means 81 in the upward / downward direction is braked by the viscous shear resistance, the manual force applied to the door 13 when the door is opened and closed Can be smoothly opened and closed without causing abrupt rotation of the arm means 81 and the door 13 even when the value is larger than usual, and generation of unpleasant noise due to the collision of the door 13 can be eliminated, In addition to extending the life, it is possible to eliminate the influence caused by the change in elastic force based on the temperature dependence of the coil spring 96, which is slightly smaller than the gas spring, but is slightly present.
[0049]
Further, in the flip-up type gate 1, since the one end portion 94 of the coil spring 96 is connected to the other end portion 91 of the roller chain 90 that is bent and guided against the cam edge 89 of the cam plate 85, the coil spring 96. As a result, it is possible to make a desired rotational moment to be applied to the cam plate 85 based on the tensile elastic force of the arm plate 81 regardless of the rotational position of the cam plate 85.
[0050]
Further, in the flip-up type gate 1, the door 13 is rotated in the direction to eliminate the protrusion of the lower end 71 of the door 13 when the door 13 is opened, and thus the protrusion of the door 13 to the front can be eliminated as much as possible. Inconveniences such as accidents and deterioration in operability are eliminated, and the use space in the door can be widened.
[0051]
In the flip-up type gate 1, the difference between the turning moment in the lowering direction of the arm means 81 based on the weight of the door 13 and the turning moment in the raising direction of the door 13 based on the elastic force of the coil spring 96 is Even if the difference in weight and center of gravity varies greatly depending on the width of the breadth, the difference can be ignored by the viscous shear resistance applied to the arm means 81 by the viscous shear resistance applying means 83 in both the up and down directions of the door 13. Thus, even if a standard kind of coil spring 96 is used for the door 13 having various widths, the middle door of the door 13 can be reliably maintained, and the door 13 can be raised and lowered. The door can be opened and closed smoothly without causing sudden rotation of the arm means 81 and the door 13 in both directions, and unpleasant noise due to the collision of the arm means 81 is generated. And obtained lost can prolong the life.
[0052]

The shaft member 35 and the connection guide means 26 are directly connected to the support column 2, and the other end 24 of the auxiliary arm member 21 is connected to the connection member 16 via another shaft member so as to be rotatable with respect to each other.
