【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】
ところで、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】
そして、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】
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、また、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。
【０００６】
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。
【０００７】
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。
【０００８】
【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、扉の下げ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、ここで、弾性力付与手段はコイルばねを具備しており、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。
【０００９】
本発明の第二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を具備しており、ここで、弾性力付与手段は、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。
【００１０】
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、しかも、中途開扉をも確実に維持できる。
【００１１】
本発明の第三の態様の跳ね上げ式門扉は、第二の態様の跳ね上げ式門扉において、扉の下げ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を具備している。
【００１２】
第三の態様の跳ね上げ式門扉によれば、第一の態様の跳ね上げ式門扉と同様に、粘性剪断抵抗力によりアーム手段の扉の下げ方向の回動が抗されるようになっているために、閉扉に際して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、スムーズに閉扉することができ、扉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る。
【００１３】
本発明の第四の態様の跳ね上げ式門扉では、第一から第三のいずれかの態様の跳ね上げ式門扉において、アーム手段は、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。
【００１４】
第四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。
【００１５】
本発明の第五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を具備しており、ここで、アーム手段は、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おり、弾性力付与手段はコイルばねを具備しており、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。
【００１６】
第五の態様の跳ね上げ式門扉によれば、第四の態様の跳ね上げ式門扉と同様に、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上に、第一及び第二の態様の跳ね上げ式門扉と同様に、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、しかも、中途開扉をも確実に維持できる。
【００１７】
本発明の第六の態様の跳ね上げ式門扉は、第五の態様の跳ね上げ式門扉において、扉の下げ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を具備している。
【００１８】
第六の態様の跳ね上げ式門扉によれば、第一及び第三の態様の跳ね上げ式門扉と同様に、粘性剪断抵抗力によりアーム手段の扉の下げ方向の回動が抗されるようになっているために、閉扉に際して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、スムーズに閉扉することができ、扉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の温度依存性に基づく弾性力の変化による影響を実質的に無効化できる。
【００１９】
第四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、第七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、第八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、第九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。
【００２０】
第七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、第八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、第九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。
【００２１】
本発明の第十の態様の跳ね上げ式門扉では、第四から第九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している。
【００２２】
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、第十一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。
【００２３】
本発明の第四から第十一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、その第十二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。
【００２４】
また第四から第十二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、その第十三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。
【００２５】
更に第四から第十三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、その第十四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。
【００２６】
本発明において弾性力付与手段は、第十五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。
【００２７】
第十五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。
【００２８】
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。
【００２９】
【発明の実施の形態】
図１から図８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２８が支柱２側のアーム手段８１の主アーム部材８の他端部１０に他端部２９が支柱３側のアーム手段８２の主アーム部材９の他端部１１に夫々固着された補強横部材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。
【００３０】
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。
【００３１】
扉１３は、上枠２７に加えて、縦枠４１及び４２と、縦枠４１及び４２を橋絡した目隠し用の多数の横格子４３と、下枠４４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）を具備している。扉１３としては、横格子４３を具備したものに限定されず、縦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。
【００３２】
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。
【００３３】
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。
【００３４】
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。
【００３５】
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６参照）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。
【００３６】
支柱２に内蔵された弾性力付与手段３１は、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。
【００３７】
カム板８５には、支柱２に固着された図示しないストッパに当接して、それ以上の回転ができないようにして、完全開扉を規定する当接部１０２が形成されており、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１０３と、円弧縁１０３に連続した直線縁１０４とを具備している。
【００３８】
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。
【００３９】
粘性剪断抵抗力付与手段８３は、粘性剪断抵抗力を発生する粘性剪断抵抗力発生機構１１１と、アーム手段８１のＢ方向の回動に基づいて粘性剪断抵抗力発生機構１１１に伝達された軸心１１０を中心とするＭ方向の回転においては粘性剪断抵抗力発生機構１１１を作動させる一方、アーム手段８１のＡ方向の回動に基づいて粘性剪断抵抗力発生機構１１１に伝達されたＬ方向の回転においては粘性剪断抵抗力発生機構１１１を非作動にさせる一方向クラッチ１１２と、軸部材６の回転を粘性剪断抵抗力発生機構１１１に伝達する伝達手段１１３とを具備している。
【００４０】
粘性剪断抵抗力発生機構１１１は、内面に同心の環状の複数の突起を一体的に有した一方の隙間形成体としてのハウジング１１５と、ハウジング１１５内に、ハウジング１１５に対して軸心１１０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１１５の複数の突起と協同してハウジング１１５内に環状及び円筒状の隙間１１６を形成する同心の環状の複数の突起を一体的に有した他方の隙間形成体１１７と、隙間形成体１１７とハウジング１１５との間の環状及び円筒状の隙間１１６に充填された粘性体１１８とを具備している。
【００４１】
粘性剪断抵抗力発生機構１１１は、ハウジング１１５と隙間形成体１１７との軸心１１０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１１８に粘性剪断抵抗力を発生させるようになっている。
【００４２】
一方向クラッチ１１２は、支柱２に固着された軸部材１２１と隙間形成体１１７との間に介在されていると共に、隙間形成体１１７のＬ方向の回転では、軸部材１２１に対して隙間形成体１１７を空転させて隙間形成体１１７のＬ方向の回転を許容して、隙間形成体１１７のＭ方向の回転では、軸部材１２１に隙間形成体１１７を固定して、当該隙間形成体１１７のＭ方向の回転を禁止するようになっている。
【００４３】
一方向クラッチ１１２は、ハウジング１１５に伝達されたＭ方向の回転においては、軸心１１０を有した軸部材１２１に隙間形成体１１７をＭ方向に回転しないように固定する結果、ハウジング１１５と隙間形成体１１７との間にＭ方向の相対回転を生じさせて、これにより、粘性体１１８に剪断変形を生じさせて粘性体１１８に粘性剪断抵抗力を発生させるように粘性剪断抵抗力発生機構１１１を作動させる一方、ハウジング１１５に伝達されたＬ方向の回転においては、軸部材１２１に対して隙間形成体１１７をＬ方向に空転可能にし、ハウジング１１５のＬ方向の回転と共に粘性体１１８を介して隙間形成体１１７をＬ方向に回転させる結果、ハウジング１１５と隙間形成体１１７との間にＬ及びＭ方向の相対回転を生じさせなくし、これにより、粘性体１１８に粘性剪断抵抗力を発生させないように粘性剪断抵抗力発生機構１１１を非作動にさせる。
【００４４】
伝達手段１１３は、軸部材６に固着された平歯車１３１と、平歯車１３１に噛合うと共にハウジング１１５に固着された平歯車１３２とを具備している。伝達手段１１３は、アーム手段８１の主アーム部材８が回動されて、主アーム部材８が固着された軸部材６が回転される際に、軸部材６に固着された平歯車１３１を回転させて、これにより平歯車１３２を介してハウジング１１５をＬ及びＭ方向に回転させるようになっている。
【００４５】
弾性力付与手段３２及び粘性剪断抵抗力付与手段８３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８４と同様に構成されている。
【００４６】
以上の跳ね上げ式門扉１では、完全閉鎖位置では図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９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９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。
【００４７】
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。
【００４８】
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９に示す軌跡ｆ−ｅ−ｄ−ｃ−ｂ−ａをもって下降する。
【００４９】
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。
【００５０】
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、一方向クラッチ１１２により隙間形成体１１７を軸部材１２１に対して空転可能とする結果、粘性体１１８を介して隙間形成体１１７をＬ方向に回転させ、したがって、ハウジング１１５と隙間形成体１１７との間に相対回転が生じなく、これにより、粘性剪断抵抗力発生機構１１１からの粘性剪断抵抗力なしに開扉を行うことができる。
【００５１】
一方、閉扉において跳ね上げ式門扉１では、図１０に示す完全開扉から手動により扉１３が下げられると、主アーム部材８がＢ方向に回動され、主アーム部材８のＢ方向の回動は一方向クラッチ１１２により隙間形成体１１７を軸部材１２１に固定させる結果、前記とは逆に、ハウジング１１５と隙間形成体１１７との間に相対回転が生じ、これにより粘性体１１８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ハウジング１１５に現出して、この粘性剪断抵抗力は、主アーム部材８のＢ方向の回動に制動を加える。
【００５２】
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。
【００５３】
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の下げ方向の回動が制動されるようになっているために、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。
【００５４】
更に跳ね上げ式門扉１では、カム板８５のカム縁８９に当接して曲げ案内されるローラチェーン９０の他端部９１にコイルばね９６の一端部９４が連結されているために、コイルばね９６の引っ張り弾性力に基づいてカム板８５に付与する回転モーメントをカム板８５の回転位置に拘わらず所望にできる結果、アーム手段８１の回動位置に最適な弾性力をアーム手段８１に付与できる。
【００５５】
また跳ね上げ式門扉１では、扉１３の開放において扉１３の下端７１のせり出しをなくす方向に扉１３が回動され、而して、扉１３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。
【００５６】
上記例では、連結部材１６の他端部２３と補助アーム部材２１の他端部２４とを共通の軸部材３５により相互に回動自在に連結し、軸部材３５にローラ５３を設けて、これにより連結部材１６の他端部２３と補助アーム部材２１の他端部２４とを連結案内手段２６を介して支柱２に連結したが、これに代えて、連結部材１６の他端部２３のみを軸部材３５及び連結案内手段２６を介して支柱２に直接的に連結し、補助アーム部材２１の他端部２４を連結部材１６に他の軸部材を介して相互に回動自在に連結してもよく、また、補助アーム部材２１の他端部２４のみを軸部材３５及び連結案内手段２６を介して支柱２に直接的に連結し、連結部材１６の他端部２３を補助アーム部材２１に他の軸部材を介して相互に回動自在に連結してもよい。
【００５７】
【発明の効果】
本発明によれば、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ができる。
【００５８】
また本発明によれば、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跳ね上げ式門扉を提供することができる。

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]
By the way, the kind of flip-up type gate described in the above publication is provided with an elastic spring-up force against the respective weights of the arm member and the door by the coil spring and the gas spring. The door is easily opened manually, but 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 is vigorous. As a result, the arm member may collide with the stopper or the like, causing 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]
And since the flip-up type gate is usually arranged outdoors where the temperature changes drastically, the gas spring is also exposed to an environment where the temperature changes drastically, and the above-mentioned inconvenience is caused by the temperature dependence of the elastic force of the gas spring. In addition to the possibility of extreme occurrence depending on the season, there may be cases where it is difficult to maintain a halfway door depending on the season.
[0005]
In addition, 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 of the door is obstructed, and the door opening / closing operability is extremely poor. Also, if the door is installed in consideration of the protruding portion, the use space in the door becomes narrow.
[0006]
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 door can be opened and closed smoothly without causing sudden rotation of the means and the door, the generation of unpleasant noise due to the collision of the arm means can be eliminated, the service life is long, and the door can be opened halfway It is to provide a flip-up type gate that can be maintained at a high speed.
[0007]
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.
[0008]
[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 the arm means, and a viscous shear resistance force against the rotation of the arm means in the door lowering direction. Viscous shear resistance force applying means for applying force to the arm means, wherein the elastic force applying means includes a coil spring, and the coil spring substantially resiliences the door in the spring-up direction. A force is applied to the arm means.
[0009]
The flip-up type gate of the second aspect of the present invention includes a support, arm means supported on the support so as to be rotatable in a vertical plane at one end, 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 in which the door is flipped up against the dead weight of the door and the arm means. Only a coil spring is provided to generate elastic force for rotating the arm means in the raising direction.
[0010]
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.
[0011]

It has a resistance applying means.
[0012]
According to the flip-up type gate of the third aspect, similarly to the flip-up type gate of the first aspect, the rotation of the arm means in the downward direction is resisted by the viscous shear resistance. Therefore, even when the manual force applied to the door when closing the door is larger than usual, the arm means and the door can be closed smoothly without causing a sudden rotation, and unpleasant noise due to the collision of the door is generated. In addition, the life can be extended, and the influence of the elastic force change based on the temperature dependency of the small amount of the compression coil spring which is extremely small compared with the gas spring can be eliminated.

[0014]
In the flip-up type gate of the fourth aspect, the connecting member and the auxiliary arm member are rotatably connected to each other in the vertical plane, and the other end of the connecting member and the auxiliary arm member are connected via the connecting guide means. 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.
[0015]
The flip-up type gate of the fifth 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 in which the door is flipped up against the dead weight of the door and the arm means.

Oh Thus, one end portion 94 of the coil spring 96 is connected to the other end portion 91 of the roller chain 90 via the connector 93, and the other end portion 97 of the coil spring 96 is connected to the support column 2 via the bracket 100 and the connector 101. It is connected.
[0037]
The cam plate 85 is formed with an abutting portion 102 that abuts against a stopper (not shown) fixed to the support column 2 so as to prevent further rotation, and defines a complete opening. The main arm member 8 includes a circular arc edge 103 centering on the rotation axis (rotation center of the shaft member 6 and the cam plate 85) 61 and a linear edge 104 continuous to the circular arc edge 103.
[0038]
The elastic force applying means 31 includes only a coil spring 96 as a member that generates a contracting elastic force that rotates the arm means 81 in the direction in which the door 13 is flipped up (direction A). A coil spring 96 applies an elastic force to the arm means 81 in the direction in which the door 13 is flipped up.
[0039]
The viscous shear resistance applying means 83 includes a viscous shear resistance generation mechanism 111 that generates a viscous shear resistance, and an axis that is transmitted to the viscous shear resistance generation mechanism 111 based on the rotation of the arm means 81 in the B direction. In the rotation in the M direction around 110, the viscous shear resistance generation mechanism 111 is operated, while the rotation in the L direction transmitted to the viscous shear resistance generation mechanism 111 based on the rotation of the arm means 81 in the A direction. 1 includes a one-way clutch 112 for disabling the viscous shear resistance generating mechanism 111 and a transmission means 113 for transmitting the rotation of the shaft member 6 to the viscous shear resistance generating mechanism 111.
[0040]
The viscous shear resistance generating mechanism 111 includes a housing 115 as one gap forming body integrally having a plurality of concentric annular protrusions on the inner surface, and the shaft center 110 is centered with respect to the housing 115 in the housing 115. A plurality of concentric annular protrusions that are relatively rotatably accommodated in both the L and M directions and form annular and cylindrical gaps 116 in the housing 115 in cooperation with the plurality of protrusions of the housing 115. The other gap forming body 117 integrally provided, and a viscous body 118 filled in an annular and cylindrical gap 116 between the gap forming body 117 and the housing 115 are provided.
[0041]
The viscous shear resistance generating mechanism 111 generates a viscous shear resistance on the viscous body 118 by relative rotation in the L and M directions around the axis 110 of the housing 115 and the gap forming body 117. Yes.
[0042]
The one-way clutch 112 is interposed between the shaft member 121 fixed to the support column 2 and the gap forming body 117, and the gap forming body is rotated with respect to the shaft member 121 when the gap forming body 117 rotates in the L direction. The gap forming body 117 is allowed to rotate in the L direction, and when the gap forming body 117 rotates in the M direction, the gap forming body 117 is fixed to the shaft member 121, and the M of the gap forming body 117 is rotated. Direction rotation is prohibited.
[0043]
The one-way clutch 112 fixes the gap forming body 117 to the shaft member 121 having the shaft center 110 so as not to rotate in the M direction during the rotation in the M direction transmitted to the housing 115. The viscous shear resistance generating mechanism 111 is caused to generate relative rotation in the M direction with the body 117, thereby causing shear deformation in the viscous body 118 and generating viscous shear resistance in the viscous body 118. On the other hand, in the rotation in the L direction transmitted to the housing 115, the gap forming body 117 can be idled in the L direction with respect to the shaft member 121, and the clearance through the viscous body 118 along with the rotation of the housing 115 in the L direction. As a result of rotating the forming body 117 in the L direction, relative rotation in the L and M directions between the housing 115 and the gap forming body 117 is prevented from occurring. Les by, is the viscous shearing resistance force generation mechanism 111 as a viscous member 118 not to generate viscous shear resistance deactivated.
[0044]
The transmission means 113 includes a spur gear 131 fixed to the shaft member 6, and a spur gear 132 that meshes with the spur gear 131 and is fixed to the housing 115. The transmission means 113 rotates the spur gear 131 fixed to the shaft member 6 when the main arm member 8 of the arm means 81 is rotated and the shaft member 6 to which the main arm member 8 is fixed is rotated. Thus, the housing 115 is rotated in the L and M directions via the spur gear 132.
[0045]
The elastic force applying means 32 and the viscous shear resistance applying means 83 are also built in the support column 3 and configured similarly to the elastic force applying means 31 and the viscous shear resistance applying means 84.
[0046]
In the flip-up type gate 1 described above, the stopper 45 comes into contact with the ground 55 as shown in FIG. 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 projecting forward as indicated by the trajectory abc of FIG. 9, and from the fully closed position (position shown in FIG. 2). Up to about 15 ° After the arm member 8 is turned in the A direction, the door 13 is moved along the A direction of the main arm member 8 and the lower end 71 of the door 13 protrudes slightly forward, and the locus cdef shown in FIG. Ascend with. 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.
[0047]
In the fully open state of the door 13 in which the lower end 71 is at the position of the locus f, the roller 53 comes into contact with the stopper 54 and further lowering of the roller 53 is prohibited. As a result, A in the vertical plane of the main arm member 8 is prevented. Further rotation of the direction becomes impossible.
[0048]
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.
[0049]
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.
[0050]
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 allows the gap forming body 117 to idle with respect to the shaft member 121 by the one-way clutch 112. Accordingly, the gap forming body 117 is rotated in the L direction, and therefore, no relative rotation occurs between the housing 115 and the gap forming body 117, thereby preventing the viscous shear resistance force from the viscous shear resistance generating mechanism 111. The door can be opened.
[0051]
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 fixing the gap forming body 117 to the shaft member 121 by the one-way clutch 112, a relative rotation occurs between the housing 115 and the gap forming body 117, which causes the viscous body 118 to be viscous sheared. Corresponding to this viscous shear, a viscous shear resistance force appears in the housing 115, and this viscous shear resistance force applies braking to the rotation of the main arm member 8 in the B direction.
[0052]
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.
[0053]
In addition, in the flip-up type gate 1, the downward movement of the door 13 of the arm means 81 is braked by the viscous shear resistance, so that the manual force applied to the door 13 when closing the door is more than usual. Even in the case of a large size, the arm means 81 and the door 13 can be closed smoothly without causing abrupt rotation, generation of unpleasant noise due to the collision of the door 13 can be eliminated, and the life can be extended. The influence of the change in elastic force based on the temperature dependence of the coil spring 96, which is very small compared to the gas spring, can be eliminated.
[0054]
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.
[0055]
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.
[0056]
In the above example, the other end portion 23 of the connecting member 16 and the other end portion 24 of the auxiliary arm member 21 are rotatably connected to each other by a common shaft member 35, and a roller 53 is provided on the shaft member 35. The other end 23 of the connecting member 16 and the other end 24 of the auxiliary arm member 21 are connected to the support column 2 via the connecting guide means 26. Instead, only the other end 23 of the connecting member 16 is connected. 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. Alternatively, only the other end 24 of the auxiliary arm member 21 is directly connected to the column 2 via the shaft member 35 and the connection guide means 26, and the other end 23 of the connection member 16 is connected to the auxiliary arm member 21. You may mutually connect through another shaft member so that rotation is possible.
