【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】
そして上記公報記載の類いの跳ね上げ式門扉に、更に、電動モータを付加して、この電動モータにより自動的にアームを回動させて扉の自動開閉を行わせるようにする場合、停電等で電動モータへの給電が行えなくなっても扉を手動で開閉できることが好ましい。
【0004】
しかしながら、手動開閉できる自動式の跳ね上げ式門扉であると、何ら関係のない第三者もまた容易に外から手動開閉できることになり、自動車の車庫等のゲートとして用いられる斯かる門扉は極めて無用心なものとなる。
【0005】
また、自動式の跳ね上げ式門扉の場合、完全閉扉及び完全開扉を確実に得るために扉又はアームの地面又はストッパ等への当接後に電動モータの作動を停止させるようにすると、当該当接後から作動停止までの間は電動モータが高負荷状態で運転されたようになり、操作者に不安感を与えると共に電動モータの寿命を短くする上に、電動モータの出力回転軸の回転をアームに伝達する回転伝達機構に無理な力が加わることになり、これまた回転伝達機構の寿命を短くし、加えて、アーム等の重量に基づく慣性により扉の地面又はストッパ等への当接が急激になされて大きな音を発生させる虞がある。
【0006】
更に、この種の跳ね上げ式門扉には、アームの自重をキャンセルして電動モータの負荷を軽減するバランサとしてガススプリングが多く用いられるが、このガススプリングの弾性力が温度によりかなり変動する結果、高温時と低温時とにおける電動モータの負荷変動で開扉及び閉扉速度が異なるようになって操作者に不安感を与えることになる。特に、跳ね上げ式門扉は、通常、温度変化の激しい屋外に配されるため、ガススプリングのこの温度変化による特性変動を無視することができないのである。
【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、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。
【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、非給電中には外からは容易に手動開閉できない上に、停電等の必要な際には容易に手動開閉が可能な自動式の跳ね上げ式門扉を提供することにある。
【0009】
本発明の他の目的とするところは、操作者に不安感を与えるような電動モータが高負荷状態で運転されるような事態を避けることができると共に完全閉扉及び完全開扉時における地面及びストッパ等への激突をなくすことができて不快な激突音をなくし得、しかも、電動モータ及び伝達機構等の寿命の低下をなくし得る跳ね上げ式門扉を提供することにある。
【0010】
本発明の更に他の目的とするところは、温度依存性をなくし得て、高温時と低温時とにおける電動モータの負荷変動で開扉及び閉扉速度が異なるような事態を避けることができ、而して、所望の全閉及び全開を行い得る跳ね上げ式門扉を提供することにある。
【0011】
また本発明の更に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。
【0012】
【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、アーム手段の回動を自動的に行うと共にアーム手段の回動に対する回動力発生源としての電動モータを有した自動アーム回動手段と、この自動アーム回動手段によるアーム手段の回動を制御する制御手段と、自動アーム回動手段の電動モータへの非給電と共にアーム手段の回動を禁止する施錠手段と、自動アーム回動手段の電動モータへの非給電中において施錠手段によるアーム手段の回動の禁止を強制的に解除すると共に支柱に手動自在に配された解除手段とを具備している。
【0013】
第一の態様の跳ね上げ式門扉によれば、施錠手段により自動アーム回動手段の電動モータへの非給電と共にアーム手段の回動を禁止するために、非給電中には外からは容易に扉を手動開閉できない上に、解除手段が支柱に手動自在に配されているために、停電等の必要な際には容易に内側から手動開閉できる。
【0014】
本発明の第二の態様の跳ね上げ式門扉では、第一の態様の跳ね上げ式門扉において、自動アーム回動手段は、電動モータの回転軸の回転をアーム手段に伝達する回転伝達機構を具備しており、施錠手段は、自動アーム回動手段の電動モータへの非給電と共に電動モータの回転軸に制動を加えてアーム手段の回動を禁止するようになっている。
【0015】
第二の態様の跳ね上げ式門扉における施錠手段は、好ましくは本発明の第三の態様の跳ね上げ式門扉のように、自動アーム回動手段の電動モータへの給電と共に電磁力を発生して電動モータの回転軸への制動を解除するようになっている。
【0016】
解除手段は、本発明の第四の態様の跳ね上げ式門扉のように、支柱に配されたグリップ部材を具備しており、グリップ部材を引くことによりアーム手段の回動の禁止を解除するようになっていても、本発明の第五の態様の跳ね上げ式門扉のように、支柱に配された摘み部を具備しており、摘み部を移動させることによりアーム手段の回動の禁止を解除するようになっていてもよい。
【0017】
なお、解除手段は、支柱に手動自在に配されるのであるが、更なる用心のために、施錠できる箱等を支柱に取付けてこの箱等の内部に解除手段を配してもよい。
【0018】
本発明の第六の態様の跳ね上げ式門扉では、上記の第一から第五のいずれかの態様の跳ね上げ式門扉において、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。
【0019】
第六の態様の跳ね上げ式門扉によれば、温度依存性が顕著なガススプリング等に代えてコイルばねを用いて実質的に扉の跳ね上げ方向への弾性力をアーム手段に付与するために、温度依存性をなくし得て、高温時と低温時とにおける電動モータの負荷変動で開扉及び閉扉速度が異なるような事態を避けることができ、而して、所望の全閉及び全開を行い得る。
【0020】
本発明の第七の態様の跳ね上げ式門扉は、第一から第六のいずれかの態様の跳ね上げ式門扉において、アーム手段の単位量の回動毎に当該アーム手段の単位量毎の回動を検出する単位回動検出手段を更に具備しており、ここで、制御手段は、単位回動検出手段の検出結果に基づいてアーム手段の回動を制御するようになっている。
【0021】
第七の態様の跳ね上げ式門扉における制御手段は、好ましくは本発明の第八の態様の跳ね上げ式門扉のように、扉の跳ね上げ又は下げ方向のアーム手段の回動で単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段の電動モータの作動を停止させるようになっている。
【0022】
第八の態様の跳ね上げ式門扉によれば、アーム手段の単位量の回動毎に当該アーム手段の単位量毎の回動を検出する単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段の電動モータの作動を停止させるようにようになっているために、換言すれば、アーム手段の回動位置を検出してこの検出した回動位置に基づいて電動モータの作動を停止させるようにようになっているために、扉及びアーム手段を地面及びストッパ等へ当接させないでも完全閉扉及び完全開扉を確実に実現でき、而して操作者に不安感を与えるような電動モータが高負荷状態で運転されるような事態を避けることができると共に完全閉扉及び完全開扉時における不快な激突音をなくし得、しかも、電動モータ及び伝達機構等の寿命の低下をなくし得る。
【0023】
本発明の第九の態様の跳ね上げ式門扉は、第七又は第八の態様の跳ね上げ式門扉において、完全開扉と完全閉扉との間でアーム手段の所定位置への回動を検出する所定位置回動検出手段を更に具備しており、制御手段は、所定位置回動検出手段からの検出結果に基づいてもアーム手段の回動を制御するようになっている。
【0024】
第九の態様の跳ね上げ式門扉によれば、所定位置回動検出手段からの検出結果に基づいてもアーム手段の回動を制御するために、所定位置回動検出手段からの検出結果を基準位置として利用できる結果、単位回動検出手段によるアーム手段の回動制御を信頼性をもって行うことができる。
【0025】
制御手段は、本発明の第十の態様の跳ね上げ式門扉のように、扉の跳ね上げ方向のアーム手段の回動において所定位置回動検出手段からの検出結果に基づいて電動モータの作動を制御してアーム手段の回動を減速させるようになっていても、本発明の第十一の態様の跳ね上げ式門扉のように、扉の跳ね上げ方向のアーム手段の回動において、所定位置回動検出手段からの検出結果の生起後、単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段の電動モータの作動を停止させるようになっていても、本発明の第十二の態様の跳ね上げ式門扉のように、扉の下げ方向のアーム手段の回動において所定位置回動検出手段からの検出結果に基づいて電動モータの作動を制御してアーム手段の回動を減速させるようになっていても、そして、本発明の第十三の態様の跳ね上げ式門扉のように、扉の下げ方向のアーム手段の回動において所定位置回動検出手段からの検出結果の生起後、単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段の電動モータの作動を停止させるようになっていてもよい。
【0026】
第十及び第十二の態様の跳ね上げ式門扉によれば、アーム手段の回動の減速後に、電動モータの作動を停止させることができるために、電動モータの作動停止に対して大きな電力を必要としなく、小さな電力で完全閉扉及び完全開扉を正確に且つ確実に行うことができる。
【0027】
また第十から第十三の態様の跳ね上げ式門扉によれば、所定位置回動検出手段からの検出結果の生起後、アーム手段の回動の減速又は電動モータの作動停止を行わせるために、減速又は作動停止が確実なものとなる。
【0028】
また制御手段は、本発明の第十四の態様の跳ね上げ式門扉のように、扉の跳ね上げ方向のアーム手段の回動において完全閉扉から単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に電動モータの作動を制御してアーム手段の回動を減速させるようになっていても、本発明の第十五の態様の跳ね上げ式門扉のように、扉の跳ね上げ方向のアーム手段の回動において完全閉扉から単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段の電動モータの作動を停止させるようになっていても、本発明の第十六の態様の跳ね上げ式門扉のように、扉の下げ方向のアーム手段の回動において完全開扉から単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に電動モータの作動を制御してアーム手段の回動を減速させるようになっていても、そして、本発明の第十七の態様の跳ね上げ式門扉のように、扉の下げ方向のアーム手段の回動において完全開扉から単位回動検出手段により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段の電動モータの作動を停止させるようになっていてもよい。
【0029】
第十四及び第十六の態様の跳ね上げ式門扉によれば、アーム手段の回動の減速後に、電動モータの作動を停止させることができるために、電動モータの作動停止に対して大きな電力を必要としなく、小さな電力で完全閉扉及び完全開扉を正確に且つ確実に行うことができる。
【0030】
弾性力付与手段は、好ましい例では本発明の第十八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。
【0031】
第十八の態様の跳ね上げ式門扉によれば、コイルばねのみ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、上述のように、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、高温時と低温時とにおける電動モータの負荷変動で開扉及び閉扉速度が異なるような事態を避けることができる。
【0032】
アーム手段は、好ましい例では本発明の第十九の態様の跳ね上げ式門扉のように、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。
【0033】
第十九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。
【0034】
連結案内手段は、本発明の第二十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、本発明の第二十一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、本発明の第二十二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。
【0035】
第二十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、第二十一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、第二十二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。
【0036】
本発明の第二十三の態様の跳ね上げ式門扉では、第十九から第二十二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。
【0037】
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、第二十四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。
【0038】
本発明の第十九から第二十四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、その第二十五の態様の跳ね上げ式門扉のように、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。
【0039】
また第十九から第二十五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、その第二十六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。
【0040】
更に第十九から第二十六のいずれかの態様の本発明の跳ね上げ式門扉では、好ましくはその第二十七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。
【0041】
本発明において弾性力付与手段は、第二十八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。
【0042】
第二十八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。
【0043】
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。
【0044】
【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横部材(横桟)30と、扉13並びにアーム手段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に付与すると共に支柱2及び3に夫々内蔵された弾性力付与手段31及び32と、アーム手段81の単位量の回動毎にアーム手段81の単位量毎の回動を検出する単位回動検出手段28と、アーム手段81の回動を自動的に行うと共にアーム手段81の回動に対する回動力発生源としての電動モータ36を有して支柱2に内蔵された自動アーム回動手段29と、完全開扉と完全閉扉との間でアーム手段81の所定位置への回動を検出する所定位置回動検出手段33と、自動アーム回動手段29によるアーム手段81の回動を単位回動検出手段28及び所定位置回動検出手段33の検出結果に基づいて制御すると共に支柱2に内蔵された制御手段34と、自動アーム回動手段29の電動モータ36への非給電と共にアーム手段81のA及びB方向の回動を禁止する一方、自動アーム回動手段29の電動モータ36への給電と共にアーム手段81のA及びB方向の回動の禁止を解除する施錠手段58と、自動アーム回動手段29の電動モータ36への非給電中において施錠手段58よるアーム手段81のA及びB方向の回動の禁止を強制的に解除すると共に支柱2に手動自在に配された解除手段59とを具備している。
【0045】
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両他端部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。
【0046】
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。
【0047】
本例では、支柱2側と支柱3側とは、単位回動検出手段28、自動アーム回動手段29、制御手段34、所定位置回動検出手段33、施錠手段58及び解除手段59を除いて、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。なお、自動アーム回動手段29と同等の自動アーム回動手段を支柱3側にも設けて、この自動アーム回動手段により支柱3側のアーム手段82の回動を支柱2側のアーム手段81と同様に自動的に行わせるようにしてもよい。支柱2側のみに自動アーム回動手段29を設ける場合には、支柱3側のアーム手段82は、支柱2側のアーム手段81に扉13及び補強横部材30を介して従属して回動されることになるので、この従属回動を行わせる程度に扉13及び補強横部材30の機械的強度を得難い際には、上記の通り、自動アーム回動手段を支柱3側にも設けて、この自動アーム回動手段により支柱3側のアーム手段82の回動を支柱2側のアーム手段81の回動と同期して自動的に行わせるようにするのがよい。なお、自動アーム回動手段を支柱3側にも設ける際には、施錠手段58及び解除手段59と同等の施錠手段及び解除手段を支柱3側にも設けるとよい。
【0048】
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。
【0049】
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の予期しない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。
【0050】
本例では、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)、すなわち完全閉扉の位置で、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、完全閉扉位置(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)、すなわち完全開扉の位置では、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。
【0051】
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。
【0052】
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、カム縁89は、軸部材6が固着された主アーム部材8の回動軸心61(軸部材6及びカム板85の回転中心)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。
【0053】
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。
【0054】
単位回動検出手段28は、支柱2内において基板104に固着された電動モータ36の回転軸37の回転を検出して、回転軸37が単位角度回転される毎にこの単位回転を示す電気的なパルスを出力するエンコーダからなり、これによりアーム手段81の単位量の回動毎にアーム手段81の単位量毎の回動を検出するようになっている。単位回動検出手段28は、回転軸37の正逆回転を識別できるように、互いに位相が異なると共に正逆回転において位相の異なりが相違する二つのパルスを回転軸37の単位回転毎に出力するようになったエンコーダからなっているとよい。なお、単位回動検出手段28としては、回転軸37の回転を検出する代わりに、軸部材6の回転を検出するようにしてアーム手段81の単位量毎の回動を検出するようにしてもよい。
【0055】
自動アーム回動手段29は、アーム手段81の回動に対する回動力発生源としての減速機付の電動モータ36と、電動モータ36の回転軸37の回転をアーム手段81に伝達する回転伝達機構60とを具備しており、回転伝達機構60は、電動モータ36の回転軸37に連結されていると共にギヤケース38に回転自在に支持されたスパイラルギヤ39と、スパイラルギヤ39に噛合うと共にカム板85の縁部に回動軸心61を中心として円弧状に伸びて形成された歯列40とを具備している。
【0056】
なお、カム板85の縁部に歯列40を設ける代わりに、軸部材6に歯車を固着し、この歯車にスパイラルギヤ39を噛合わせて回転伝達機構60を構成してもよい。
【0057】
可逆の電動モータ36は、ブラケット56を介して基板104に固着されており、ギヤケース38は基板104に取付けられており、回転軸37は、連結具57を介してスパイラルギヤ39に連結されている。
【0058】
自動アーム回動手段29は、制御手段34の制御下で、電動モータ36の回転軸37を正又は逆転させてスパイラルギヤ39を介して歯列40を移動させ、歯列40の移動によりカム板85及び軸部材6を介してアーム手段81をA又はB方向に自動的に回動させるようになっている。
【0059】
所定位置回動検出手段33は、軸部材6に固着されていると共に円弧突部48を一体的に有した円板49と、支柱2に取付けられたリミットスイッチ50とを具備している。
【0060】
所定位置回動検出手段33は、軸部材6がA方向に回転されてアーム手段82が所定回動位置に回動された際に、円弧突部48がリミットスイッチ50に当接してリミットスイッチ50を作動させて、斯かるリミットスイッチ50の作動でもって扉13の完全開扉と完全閉扉との間でアーム手段81の所定位置への回動を検出するようになっている。本例では、所定位置回動検出手段33は、アーム手段82のA方向の回動で、所定位置として完全開扉から角度で10°手前の位置で円弧突部48がはじめてリミットスイッチ50に当接してリミットスイッチ50を作動させると共に以後完全開扉までリミットスイッチ50の作動を維持するようになっている。
【0061】
制御手段34は、コンピュータ等からなり、扉13の跳ね上げ方向及び下げ方向、即ちA及びB方向のアーム手段81の回動で単位回動検出手段28により検出された単位量毎の回動の回数が所定値に到達した際に自動アーム回動手段29の電動モータ36への給電を停止(非給電)し、電動モータ36の作動を停止させるようになっていると共に、A及びB方向のアーム手段81の回動において所定位置回動検出手段33からの検出結果に基づいて電動モータ36の作動を制御してアーム手段81の回動を減速させるようになっている。
【0062】
即ち、制御手段34は、図1及び図2に示す完全閉扉で、支柱2等に取付けられた図示しないスイッチが操作者により押圧されると、電動モータ36に給電して回転軸37を例えば1700rpmないし1400rpmで回転させるように電動モータ36を作動させ、これにより回転軸37、スパイラルギヤ39、歯列40、カム板85及び軸部材6を介してA方向にアーム手段81を回動させて扉13を跳ね上げさせると共に、スイッチの押圧以後、アーム手段81のA方向の回動中において単位回動検出手段28からの単位量毎の回動を示すパルスを計数し続け、次に完全開扉から角度で10°手前の位置までアーム手段81が回動されたことを示す検出結果が所定位置回動検出手段33から生起されてこの検出結果を所定位置回動検出手段33から受け取ると、回転軸37を例えば300rpmないし500rpmで減速して回転させるように電動モータ36を作動させ、その後、単位量毎の回動の回数を示すパルスの計数値が、完全開扉となるアーム手段81の回動位置として予め設定された値になると電動モータ36の作動を停止させるべく、電動モータ36への給電を停止(非給電)するようになっている。
【0063】
そして制御手段34は、図10及び図11に示すように扉13の下端71がfの位置となる完全開扉状態で、図示しない上記のスイッチが操作者により押圧されることにより、電動モータ36に給電して回転軸37を例えば1700rpmないし1400rpmで回転させるように電動モータ36を逆に作動させ、これにより回転軸37、スパイラルギヤ39、歯列40、カム板85及び軸部材6を介してB方向にアーム手段81を回動させて扉13を下げさせると共に、スイッチの押圧以後、アーム手段81のB方向の回動中において単位回動検出手段28からの単位量毎の回動を示すパルスでもって前述の計数値を減算し続け、この減算された計数値が完全閉扉から角度で15°手前の位置までのアーム手段81の回動量に相当する予め設定された値になると、回転軸37を例えば300rpmないし500rpmで減速して回転するように電動モータ36を作動させ、その後、アーム手段81の単位量毎の回動の回数を示すパルスの計数値が完全開扉となるアーム手段81の回動位置として予め設定された値、この場合、パルスの計数値がゼロになると電動モータ36の作動を停止させるべく、電動モータ36への給電を停止(非給電)するようになっている。
【0064】
また、制御手段34は、単位回動検出手段28からの単位量毎の回動を示すパルスの生起時間間隔から回転軸37の回転速度を検出して、この検出結果に基づいて、回転軸37の回転速度が予め決められた1700rpmないし1400rpm及び300rpmないし500rpmとなるように制御している。
【0065】
緊急事態によるアーム手段81の回動の途中停止では、制御手段34は、その時点におけるパルスの計数値を記憶し、操作者によるスイッチの押圧でパルスの計数又は減算を続行するようになっている。
【0066】
更に、所定位置回動検出手段33から検出結果が出力されるアーム手段81の回動位置は予め判明しているために、制御手段34は、所定位置回動検出手段33から検出結果を受け取った際において、パルスの計数値が、所定位置回動検出手段33から検出結果が出力されるアーム手段81の回動位置に相当しない値である場合には、このパルスの計数値を当該アーム手段81の回動位置に相当する値に修正するようになっている。
【0067】
なお、リミットスイッチ50に加えて更に他のリミットスイッチを具備して所定位置回動検出手段33を構成し、アーム手段82のB方向の回動で、所定位置として完全閉扉から角度で15°手前の位置で円弧突部48がはじめて斯かる他のリミットスイッチに当接して当該リミットスイッチを作動させると共に以後完全閉扉まで当該リミットスイッチの作動を維持するように所定位置回動検出手段33を構成してもよく、この場合に、制御手段34は、B方向のアーム手段81の回動において所定位置回動検出手段33から他のリミットスイッチの検出結果に基づいて電動モータ36の作動を制御してアーム手段81の回動を減速させるようにしてもよい。
【0068】
また、所定位置回動検出手段33を設けることなしに、A方向のアーム手段の回動において、B方向のアーム手段81の回動と同様に、完全閉扉から単位回動検出手段28により検出された単位量毎の回動の回数を示すパルスの計数値が予め決められた所定値に到達した際に電動モータ36の作動を制御してアーム手段81の回動を減速させるように制御手段34を構成してもよい。
【0069】
施錠手段58は、電磁石、ばね、可動鉄片、摩擦板等を具備した電磁クラッチ等からなっており、自動アーム回動手段29の電動モータ36への給電と共に電磁石への給電を行って電磁力を発生しこの電磁力でもってばねのばね力に抗して可動鉄片及び摩擦板を動かして電動モータ36の回転軸37への制動を解除して回転軸37の回転を可能とし、自動アーム回動手段29の電動モータ36への非給電と共に電磁石も非給電として電動モータ36の回転軸37にばねのばね力に基づく摩擦板の摩擦制動を加えて回転軸37の回転を禁止するようになっている。
【0070】
このように施錠手段58は、電動モータ36が非給電となると、電動モータ36の回転軸37に制動を与えて回転軸37が回転できないようにして、而して回転軸37にスパイラルギヤ39、歯列40、カム板85及び軸部材6を介して連結されたアーム手段81もまたA及びB方向に回動できないようにし、アーム手段81の回動を禁止するようになっている。
【0071】
解除手段59は、施錠手段58のばね力に抗して摩擦板を動かして摩擦制動を解除するように揺動自在に施錠手段58に配された解除レバー72と、解除レバー72に一端が連結された紐状体としてのワイヤ73と、ワイヤ73の他端に連結されていると共に支柱2の外側に垂れ下げて操作可能に配されたグリップ部材74と、一端がワイヤ73に他端が支柱2に取付けられた引き戻し用のコイルばね70とを具備しており、ワイヤ73は、支柱2に回転自在に支持された転向プーリ75に掛け回されて支柱2に形成された孔76を通って配されている。
【0072】
解除手段59は、停電等を含む電動モータ36への非給電中において必要により人手によりグリップ部材74が引かれてワイヤ73が引っ張られると、解除レバー72を揺動させるようになっている。解除レバー72は、ワイヤ73に引っ張られて揺動されると、てこの原理でもって、施錠手段58における電動モータ36の回転軸37に対するばね力に基づく摩擦制動を解除するようになっており、而して、解除手段59は、電動モータ36への非給電中において斯かる施錠手段58における摩擦制動を解除して、電動モータ36の回転軸37にスパイラルギヤ39、歯列40、カム板85及び軸部材6を介して連結されたアーム手段81の回動の禁止を解除するようになっている。施錠手段58によるアーム手段81の回動の禁止がこうして解除されると、アーム手段81を手動でA及びB方向に回動できるようになって扉13の開閉を手動で行うことができるようになる。
【0073】
なお、孔76から引き出されたワイヤ73を巻き付けることができるように支柱2に取付けられたピン又はワイヤ73を引っ張るために移動されたグリップ部材74を着脱自在に保持できるように支柱2に取付けられた保持具等を更に具備して解除手段59を構成し、斯かるピンへのワイヤ73の巻き付け又は保持具へのグリップ部材74の保持でもって施錠手段58に対する解除状態を維持できるようにしてもよい。
【0074】
以上の跳ね上げ式門扉1では、完全閉扉では図1及び図2に示すように扉13が地面55にほぼ直立した状態になる。この状態で操作者による図示しないスイッチの作動で電動モータ36及び施錠手段58への給電がなされて、電動モータ36が作動される一方、施錠手段58による電動モータ36の回転軸37への制動が解除され、電動モータ36の作動による回転軸37の回転で、スパイラルギヤ39、歯列40、カム板85及び軸部材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、完全閉扉位置(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をもって上昇し、最後に下端71が軌跡fの位置となる完全開扉となると電動モータ36及び施錠手段58への給電が停止されて電動モータ36の作動が停止されると共に施錠手段58による電動モータ36の回転軸37への制動が行われる。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。
【0075】
完全開扉から完全閉扉にするには、操作者による図示しないスイッチの作動による電動モータ36の逆作動で軸部材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の完全閉扉への移行でも、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。
【0076】
跳ね上げ式門扉1では、コイルばね96により扉13等の自重を適宜打ち消す縮み弾性力を発生するようにしているために、完全閉扉において、スパイラルギヤ39と歯列40との間の噛合い部にそれ程の力が負荷されず、電動モータ36の作動での開扉作動を困難なく行い得る。また、電動モータ36の作動でアーム手段81がA方向に回動されると、これと共にカム板85も図10に示すように同様にA方向に回転される結果、アーム手段81の各回動位置に相当して生じるコイルばね96の引っ張り弾性力でもって、扉13等の自重が適宜打ち消されて自動開扉が困難なく行えるようになっている。
【0077】
跳ね上げ式門扉1では、コイルばね96のみにより扉13の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、電動モータ36の負荷変動で開扉及び閉扉速度が異なるような事態を避けることができる。
【0078】
跳ね上げ式門扉1によれば、アーム手段81の単位量の回動毎にアーム手段81の単位量毎の回動を検出する単位回動検出手段28により検出された単位量毎の回動の回数に相当するパルスの計数値が所定値に到達した際に自動アーム回動手段29の電動モータ36の作動を停止させるようになっているために、換言すれば、アーム手段81の回動位置を検出してこの検出した回動位置に基づいて電動モータ36の作動を停止させるようになっているために、扉13及びアーム手段81を地面及びストッパ等へ当接させないでも完全閉扉及び完全開扉を確実に実現でき、而して操作者に不安感を与えるような電動モータ36が高負荷状態で運転されるような事態を避けることができると共に完全閉扉及び完全開扉時における不快な激突音をなくし得、しかも、電動モータ36並びにスパイラルギヤ39及び歯列40を含む回転伝達機構60等の寿命の低下をなくし得る。
【0079】
そして、跳ね上げ式門扉1によれば、所定位置回動検出手段33からの検出結果に基づいてもアーム手段81の回動を制御するために、所定位置回動検出手段33からの検出結果を基準位置として利用できる結果、単位回動検出手段28によるアーム手段81の回動制御を信頼性をもって行うことができる。
【0080】
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。
【0081】
加えて跳ね上げ式門扉1によれば、アーム手段81の回動の減速後に、電動モータ36の作動を停止させるために、電動モータ36の作動停止に対して大きな電力を必要としなく、小さな電力で完全閉扉及び完全開扉を正確に且つ確実に行うことができる。
【0082】
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。
【0083】
跳ね上げ式門扉1によれば、施錠手段58により自動アーム回動手段29の電動モータ36への非給電と共にアーム手段81の回動を禁止するために、非給電中には外からは容易に扉13を手動開閉できない上に、解除手段59が支柱2に手動自在に配されているために、停電等の必要な際には解除手段59により施錠手段58の施錠状態を解除でき、容易に内側から扉13を手動開閉できる。
【0084】
なお、解除手段59を図12に示すように構成してもよく、図12に示す解除手段59は、解除レバー72に加えて、支柱2に取付けられたハウジング77と、支柱2に配されたスライド摘み78と、ハウジング77内に配されていると共にスライド摘み78を元の位置に復帰させるように弾性的に付勢するコイルばね79とを具備しており、ハウジング77は係合孔80を有しており、スライド摘み78は、ハウジング77内に摺動自在に配された本体110と、本体110の一方の面に一体的に形成されていると共にハウジング77の孔111を介してハウジング77外に突出して支柱2に配された摘み部112と、同じく本体110の一方の面に一体的に形成された突部113と、本体110の他方の面に一体的に形成されていると共に支柱2に形成された貫通孔114を通って解除レバー72に係合する係合突起部115とを具備している。
【0085】
図12に示す解除手段59によれば、手動で摘み部112を移動させてスライド摘み78を下方にスライドさせることにより、係合突起部115を介して解除レバー72を揺動させることことができ、これによりアーム手段81の回動の禁止を解除できるようになっている。そして図12の解除手段59では、スライド摘み78の下方へのスライドにおいて、突部113が係合孔80に嵌入するようになっているために解除レバー72の揺動状態を維持できるようになっており、この解除レバー72の揺動状態の解除は、手動で摘み部112を介してスライド摘み78を支柱2に向かって押し付けて係合孔80から突部113を抜出させて、コイルばね79によりスライド摘み78を上方にスライドさせることにより行い得る。
【0086】
更に図13及び図14に示すように解除手段59を構成してもよく、図13及び図14に示す解除手段59は、貫通孔114を通って支柱2外に突出した解除レバー72と、支柱2内面に固着されていると共に中央部で曲折して突出した板ばね118とを具備しており、解除レバー72は、その自由端部側に摘み部としての二股部119を有しており、板ばね118は、支柱2に配された二股部119の間を通って支柱2内面にねじなどにより固着されている。図13及び図14の解除手段59では、手動で二股部119を移動させて解除レバー72を直接揺動させることによりアーム手段81の回動の禁止を解除できるようになっており、この直接揺動において解除レバー72の二股部119の基部が板ばね118のばね変形を伴って板ばね118の曲折して突出した部位を乗り越えて当該部位に係合するようになっているために解除レバー72の揺動状態を維持でき、解除レバー72を手動で前記と逆に直接揺動させて板ばね118のばね変形を伴って板ばね118の曲折して突出した部位と二股部119の基部との係合を解除することによって解除レバー72の揺動状態の解除を行い得るようになっている。
【0087】
また上記例では、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、更にまた、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。
【0088】

【0090】
更に本発明によれば、温度依存性をなくし得て、高温時と低温時とにおける電動モータの負荷変動で開扉及び閉扉速度が異なるような事態を避けることができ、而して、所望の全閉及び全開を行い得る跳ね上げ式門扉を提供することができる。

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]
In addition, when an electric motor is further added to the flip-up type gate door described in the above publication, the arm is automatically rotated by the electric motor to automatically open and close the door. Therefore, it is preferable that the door can be manually opened and closed even when the electric motor cannot be supplied with power.
[0004]
However, an automatic flip-up type gate that can be manually opened and closed allows any unrelated third party to easily manually open and close from the outside, and there is no such gate used as a gate in an automobile garage or the like. Be cautious.
[0005]
In addition, in the case of an automatic flip-up type gate, if the operation of the electric motor is stopped after the door or arm abuts against the ground or a stopper in order to reliably obtain a fully closed door and a fully opened door, The electric motor seems to have been operated in a high load state from the time of contact until the operation is stopped, which causes anxiety to the operator and shortens the life of the electric motor. An unreasonable force is applied to the rotation transmission mechanism that transmits to the arm. This also shortens the life of the rotation transmission mechanism, and in addition, the contact of the door with the ground or stopper due to the inertia of the weight of the arm or the like. There is a risk of generating a loud sound when made suddenly.
[0006]
Furthermore, in this kind of flip-up type gate, a gas spring is often used as a balancer that cancels the weight of the electric motor by canceling the weight of the arm, but the elastic force of this gas spring varies considerably with temperature. The opening and closing speeds differ depending on the load fluctuation of the electric motor at high temperature and low temperature, which gives the operator anxiety. In particular, since the flip-up type gate is usually arranged outdoors where the temperature changes drastically, the characteristic fluctuation due to the temperature change of the gas spring cannot be ignored.
[0007]
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.
[0008]
The present invention has been made in view of the above-mentioned points, and the object of the present invention is that it cannot be easily manually opened and closed from the outside during non-power feeding and is easily manually operated when a power failure or the like is necessary. The object is to provide an automatic flip-up gate that can be opened and closed.
[0009]
Another object of the present invention is to avoid a situation in which an electric motor that causes anxiety to the operator is operated in a high load state, and at the time of complete closing and full opening, the ground and stopper It is an object of the present invention to provide a flip-up gate that can eliminate an unpleasant crashing noise and can eliminate an unpleasant crashing noise, and can eliminate a decrease in the life of an electric motor, a transmission mechanism, and the like.
[0010]
Still another object of the present invention is to eliminate temperature dependence, and to avoid a situation in which the opening and closing speeds differ due to load fluctuations of the electric motor at high temperature and low temperature. Then, it is providing the flip-up type gate which can perform desired full closure and full open.
[0011]
Still another object of the present invention is to provide a flip-up type gate that can eliminate the inconvenience of the door as much as possible, eliminates inconvenience such as an accident caused by the protrusion, and widens the use space in the door. There is to do.
[0012]
[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 the arm means is automatically rotated and the arm means is not rotated. Automatic arm rotation means having an electric motor as a power generation source, control means for controlling the rotation of the arm means by the automatic arm rotation means, and non-power supply to the electric motor of the automatic arm rotation means The locking means for prohibiting the rotation of the arm means and the prohibition of the rotation of the arm means by the locking means during the non-power supply to the electric motor of the automatic arm rotation means are forcibly canceled and are manually disposed on the column. Release means It is.
[0013]
According to the flip-up type gate of the first aspect, the locking means prohibits the automatic arm rotation means from supplying power to the electric motor and prohibits the rotation of the arm means. Since the door cannot be manually opened and closed, and the release means is manually arranged on the column, it can be easily opened and closed manually from the inside when a power failure or the like is necessary.
[0014]
In the flip-up gate of the second aspect of the present invention, in the flip-up gate of the first aspect, the automatic arm rotation means includes a rotation transmission mechanism that transmits the rotation of the rotation shaft of the electric motor to the arm means. The locking means is configured not to supply power to the electric motor of the automatic arm rotation means and to apply braking to the rotation shaft of the electric motor to inhibit the rotation of the arm means.
[0015]
The locking means in the flip-up gate of the second aspect preferably generates an electromagnetic force together with the power supply to the electric motor of the automatic arm turning means, like the flip-up gate of the third aspect of the present invention. The brake to the rotating shaft of the electric motor is released.
[0016]
The release means has a grip member arranged on the support like the flip-up type gate of the fourth aspect of the present invention, and the prohibition of the rotation of the arm means is released by pulling the grip member. Even if it is, like the flip-up type gate of the fifth aspect of the present invention, it has a knob portion arranged on the support column, and the rotation of the arm means is prohibited by moving the knob portion. You may come to cancel.
[0017]
The release means is manually disposed on the support column. However, for further precautions, a lockable box or the like may be attached to the support column and the release means may be provided inside the box.
[0018]
In the flip-up gate according to the sixth aspect of the present invention, in the flip-up gate according to any of the first to fifth aspects, the elastic force applying means includes a coil spring, An elastic force in the direction in which the door is flipped up is applied to the arm means by a coil spring.
[0019]
According to the flip-up type gate of the sixth aspect, in order to substantially give elastic force to the arm means in the spring-up direction of the door using a coil spring instead of the gas spring having a remarkable temperature dependency. The temperature dependency can be eliminated, and the situation where the opening and closing speeds are different due to the load fluctuation of the electric motor at high temperature and low temperature can be avoided, and thus the desired full closing and full opening can be performed. obtain.
[0020]
The flip-up gate according to the seventh aspect of the present invention is the flip-up gate according to any one of the first to sixth aspects, wherein the arm means is rotated each time the unit amount of the arm means is rotated. Unit rotation detecting means for detecting movement is further provided. Here, the control means controls the rotation of the arm means based on the detection result of the unit rotation detecting means.
[0021]
The control means in the flip-up type gate of the seventh aspect is preferably unit rotation detection by turning the arm means in the direction of raising or lowering the door, like the flip-up type gate of the eighth aspect of the present invention. When the number of rotations per unit amount detected by the means reaches a predetermined value, the operation of the electric motor of the automatic arm rotation means is stopped.
[0022]
According to the flip-up type gate of the eighth aspect, every unit amount detected by the unit rotation detecting means for detecting the rotation for each unit amount of the arm means for each rotation of the unit amount of the arm means. Since the operation of the electric motor of the automatic arm rotation means is stopped when the number of movements reaches a predetermined value, in other words, the rotation position of the arm means is detected and detected. Since the operation of the electric motor is stopped based on the rotated position, it is possible to reliably realize complete closing and complete opening without bringing the door and arm means into contact with the ground and stopper, etc. Thus, it is possible to avoid a situation in which an electric motor that causes anxiety to the operator is operated in a high load state, and to eliminate an unpleasant crashing noise when the door is completely closed and fully opened, and the electric motor Motor and transmission mechanism It may eliminate the reduction in service life.
[0023]
The flip-up gate of the ninth aspect of the present invention is the flip-up gate of the seventh or eighth aspect, and detects the rotation of the arm means to a predetermined position between the fully open door and the fully closed door. A predetermined position rotation detection means is further provided, and the control means controls the rotation of the arm means based on the detection result from the predetermined position rotation detection means.
[0024]
According to the flip-up type gate of the ninth aspect, in order to control the rotation of the arm means based on the detection result from the predetermined position rotation detection means, the detection result from the predetermined position rotation detection means is used as a reference. As a result of being usable as the position, the rotation control of the arm means by the unit rotation detection means can be performed with reliability.
[0025]
As in the flip-up type gate of the tenth aspect of the present invention, the control means controls the operation of the electric motor based on the detection result from the predetermined position rotation detection means in the rotation of the arm means in the door flip-up direction. Even if the arm means is controlled to decelerate the rotation, like the flip-up type gate of the eleventh aspect of the present invention, the arm means is rotated at a predetermined position in the turning direction of the arm means. After the detection result from the rotation detection means is generated, the operation of the electric motor of the automatic arm rotation means is stopped when the number of rotations per unit amount detected by the unit rotation detection means reaches a predetermined value. Even in this case, like the flip-up type gate of the twelfth aspect of the present invention, the electric motor is based on the detection result from the predetermined position rotation detection means in the rotation of the arm means in the door lowering direction. Controlling the movement of the arm means reduces the rotation of the arm means And the occurrence of the detection result from the predetermined position rotation detection means in the rotation of the arm means in the door lowering direction as in the flip-up type gate of the thirteenth aspect of the present invention. Thereafter, when the number of rotations per unit amount detected by the unit rotation detection unit reaches a predetermined value, the operation of the electric motor of the automatic arm rotation unit may be stopped.
[0026]
According to the flip-up type gate of the tenth and twelfth aspects, since the operation of the electric motor can be stopped after the rotation of the arm means is decelerated, a large electric power is required for the stop of the operation of the electric motor. It is not necessary, and the complete closing and the complete opening can be performed accurately and reliably with a small electric power.
[0027]
Further, according to the flip-up type gate of the tenth to thirteenth aspects, after the detection result from the predetermined position rotation detecting means occurs, the arm means is decelerated or the electric motor is stopped. As a result, deceleration or deactivation is ensured.
[0028]
Further, the control means, like the flip-up type gate of the fourteenth aspect of the present invention, for each unit amount detected by the unit rotation detection means from the fully closed door in the rotation of the arm means in the door flip-up direction. Even if the rotation of the arm means is decelerated by controlling the operation of the electric motor when the number of rotations reaches a predetermined value, it is like the flip-up type gate of the fifteenth aspect of the present invention. In addition, the electric motor of the automatic arm rotation means when the number of rotations per unit amount detected by the unit rotation detection means from the fully closed door in the rotation of the arm means in the direction of raising the door reaches a predetermined value. Even when the operation of the arm means is stopped, like the flip-up type gate of the sixteenth aspect of the present invention, the unit means for detecting the rotation of the arm means in the downward direction of the door from the fully opened door The number of rotations per unit amount detected reaches a predetermined value. Even when the operation of the electric motor is controlled to decelerate the rotation of the arm means, the door is lowered in the downward direction as in the flip-up type gate of the seventeenth aspect of the present invention. The operation of the electric motor of the automatic arm rotation means is stopped when the number of rotations per unit amount detected by the unit rotation detection means from the fully opened door in the rotation of the arm means reaches a predetermined value. It may be.
[0029]
According to the flip-up gates of the fourteenth and sixteenth aspects, the electric motor can be stopped after deceleration of the rotation of the arm means. Therefore, it is possible to accurately and reliably perform the complete closing and the complete opening with a small electric power.
[0030]
In a preferred example, the elastic force applying means includes only a coil spring as generating elastic force for rotating the arm means in the direction in which the door is flipped up, such as the flip-up type gate of the eighteenth aspect of the present invention. is doing.
[0031]
According to the flip-up type gate of the eighteenth aspect, since the contraction elastic force that rotates the arm means in the door flip-up direction is generated only by the coil spring, the gas spring is used as described above. As a result of eliminating the temperature dependence as compared with the above, it is possible to avoid a situation in which the opening and closing speeds differ due to load fluctuations of the electric motor at high temperature and low temperature.

[0053]
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.
[0054]
The unit rotation detecting means 28 detects the rotation of the rotating shaft 37 of the electric motor 36 fixed to the substrate 104 in the support column 2, and indicates the unit rotation every time the rotating shaft 37 is rotated by a unit angle. It is composed of an encoder that outputs a simple pulse, so that the rotation of the arm means 81 per unit amount is detected every time the arm means 81 rotates. The unit rotation detection means 28 outputs two pulses having different phases and different phases in forward and reverse rotation for each unit rotation of the rotary shaft 37 so that the forward and reverse rotations of the rotary shaft 37 can be identified. It is good that it consists of the encoder which became. As the unit rotation detection means 28, instead of detecting the rotation of the rotary shaft 37, the rotation of the arm means 81 may be detected by detecting the rotation of the shaft member 6. Good.
[0055]
The automatic arm rotation means 29 includes an electric motor 36 with a speed reducer as a power generation source for the rotation of the arm means 81, and a rotation transmission mechanism 60 that transmits the rotation of the rotating shaft 37 of the electric motor 36 to the arm means 81. The rotation transmission mechanism 60 is connected to the rotation shaft 37 of the electric motor 36 and is rotatably supported by the gear case 38. The rotation transmission mechanism 60 meshes with the spiral gear 39 and is connected to the cam plate 85. And a tooth row 40 formed to extend in an arc shape around the rotation axis 61.
[0056]
Instead of providing the tooth row 40 at the edge of the cam plate 85, a rotation transmission mechanism 60 may be configured by fixing a gear to the shaft member 6 and meshing the spiral gear 39 with the gear.
[0057]
The reversible electric motor 36 is fixed to the substrate 104 via a bracket 56, the gear case 38 is attached to the substrate 104, and the rotary shaft 37 is connected to the spiral gear 39 via a connector 57. .
[0058]
Under the control of the control means 34, the automatic arm rotation means 29 moves the tooth row 40 via the spiral gear 39 by rotating the rotating shaft 37 of the electric motor 36 forward or backward, and the cam plate is moved by the movement of the tooth row 40. The arm means 81 is automatically rotated in the A or B direction via the shaft 85 and the shaft member 6.
[0059]
The predetermined position rotation detection means 33 includes a disk 49 that is fixed to the shaft member 6 and has an arcuate protrusion 48 integrally, and a limit switch 50 that is attached to the column 2.
[0060]
The predetermined position rotation detection means 33 is configured such that when the shaft member 6 is rotated in the A direction and the arm means 82 is rotated to the predetermined rotation position, the arc projection 48 contacts the limit switch 50 and the limit switch 50 is rotated. And the rotation of the arm means 81 to a predetermined position is detected between the fully opened door and the fully closed door 13 by the operation of the limit switch 50. In this example, the predetermined position rotation detection means 33 is the rotation of the arm means 82 in the A direction, and the arc projection 48 first hits the limit switch 50 at a position 10 degrees before the complete opening as a predetermined position. The limit switch 50 is operated in contact with it, and the operation of the limit switch 50 is maintained until the door is completely opened.
[0061]
The control means 34 is composed of a computer or the like, and the rotation of the unit 13 detected by the unit rotation detecting means 28 by the rotation of the arm means 81 in the direction in which the door 13 is flipped up and down, that is, in the A and B directions. When the number of times reaches a predetermined value, power supply to the electric motor 36 of the automatic arm rotation means 29 is stopped (non-powered), and the operation of the electric motor 36 is stopped. The rotation of the arm unit 81 is decelerated by controlling the operation of the electric motor 36 based on the detection result from the predetermined position rotation detection unit 33 in the rotation of the arm unit 81.
[0062]
That is, the control means 34 is a completely closed door shown in FIGS. 1 and 2, and when a switch (not shown) attached to the column 2 or the like is pressed by an operator, the control means 34 supplies power to the electric motor 36 to rotate the rotating shaft 37, for example, 1700 rpm. The electric motor 36 is operated so as to rotate at 1400 rpm, and thereby the arm means 81 is rotated in the A direction via the rotating shaft 37, the spiral gear 39, the tooth row 40, the cam plate 85 and the shaft member 6. 13, and after the switch is pressed, while the arm means 81 is rotating in the direction A, the unit rotation detecting means 28 continues to count pulses indicating the rotation for each unit amount, and then fully opens the door. A detection result indicating that the arm means 81 has been rotated to a position 10 ° before the angle from the angle is generated from the predetermined position rotation detection means 33, and this detection result is detected as a predetermined position rotation. When received from the stage 33, the electric motor 36 is operated so as to rotate the rotating shaft 37 at a reduced speed of, for example, 300 rpm to 500 rpm, and then the pulse count value indicating the number of rotations per unit amount is fully opened. In order to stop the operation of the electric motor 36, the power supply to the electric motor 36 is stopped (non-powered) in order to stop the operation of the electric motor 36.
[0063]
As shown in FIGS. 10 and 11, the control means 34 is in the fully open state in which the lower end 71 of the door 13 is at the position f, and the switch (not shown) is pressed by the operator, so that the electric motor 36 The electric motor 36 is operated in reverse so that the rotating shaft 37 is rotated at, for example, 1700 rpm to 1400 rpm by supplying power to the rotating shaft 37, thereby causing the rotating shaft 37, the spiral gear 39, the tooth row 40, the cam plate 85 and the shaft member 6 to pass through. The arm means 81 is rotated in the B direction to lower the door 13, and after the switch is pressed, the rotation of the unit means from the unit rotation detecting means 28 during the rotation of the arm means 81 in the B direction is shown. The aforementioned count value is continuously subtracted with a pulse, and the subtracted count value corresponds in advance to the amount of rotation of the arm means 81 from the fully closed door to a position 15 ° before the angle. When the predetermined value is reached, the electric motor 36 is operated so as to rotate the rotating shaft 37 at a speed of, for example, 300 rpm to 500 rpm, and then the pulse count value indicating the number of rotations of the arm means 81 per unit amount. Is a value set in advance as the rotational position of the arm means 81 that is fully opened, and in this case, when the pulse count value becomes zero, power supply to the electric motor 36 is stopped in order to stop the operation of the electric motor 36 ( Non-powered).
[0064]
Further, the control means 34 detects the rotational speed of the rotary shaft 37 from the occurrence time interval of the pulses indicating the rotation for each unit amount from the unit rotation detection means 28, and based on the detection result, the rotary shaft 37 is detected. The rotation speed is controlled so as to be predetermined 1700 rpm to 1400 rpm and 300 rpm to 500 rpm.
[0065]
In the midway stop of the rotation of the arm unit 81 due to an emergency situation, the control unit 34 stores the pulse count value at that time and continues counting or subtracting the pulse by pressing the switch by the operator. .
[0066]
Further, since the rotation position of the arm unit 81 from which the detection result is output from the predetermined position rotation detection unit 33 is known in advance, the control unit 34 receives the detection result from the predetermined position rotation detection unit 33. In this case, if the count value of the pulse is a value that does not correspond to the rotation position of the arm means 81 from which the detection result is output from the predetermined position rotation detection means 33, the count value of the pulse is used as the arm means 81. The value is corrected to a value corresponding to the rotation position.
[0067]
Further, in addition to the limit switch 50, another limit switch is provided to constitute the predetermined position rotation detection means 33, and when the arm means 82 rotates in the B direction, the predetermined position is 15 degrees before the fully closed door. The predetermined position rotation detecting means 33 is configured so that the arc projection 48 first contacts with the other limit switch at the position to activate the limit switch and maintain the operation of the limit switch until the door is completely closed thereafter. In this case, the control unit 34 controls the operation of the electric motor 36 based on the detection result of the other limit switch from the predetermined position rotation detection unit 33 in the rotation of the arm unit 81 in the B direction. The rotation of the arm means 81 may be decelerated.
[0068]
Further, without providing the predetermined position rotation detection means 33, the rotation of the arm means in the A direction is detected by the unit rotation detection means 28 from the completely closed door, similarly to the rotation of the arm means 81 in the B direction. The control unit 34 controls the operation of the electric motor 36 to decelerate the rotation of the arm unit 81 when the count value of the pulse indicating the number of rotations per unit amount reaches a predetermined value. May be configured.
[0069]
The locking means 58 is composed of an electromagnetic clutch or the like having an electromagnet, a spring, a movable iron piece, a friction plate, and the like. The automatic arm rotating means 29 supplies power to the electric motor 36 as well as power to the electromagnet to generate electromagnetic force. With this electromagnetic force, the movable iron piece and the friction plate are moved against the spring force of the spring to release the braking to the rotating shaft 37 of the electric motor 36 and to enable the rotating shaft 37 to rotate, and the automatic arm rotation In addition to the non-power supply to the electric motor 36 of the means 29, the electromagnet is also non-powered to apply friction braking of the friction plate based on the spring force of the spring to the rotation shaft 37 of the electric motor 36 to inhibit the rotation of the rotation shaft 37. Yes.
[0070]
Thus, when the electric motor 36 is de-energized, the locking means 58 applies braking to the rotating shaft 37 of the electric motor 36 so that the rotating shaft 37 cannot rotate. The arm means 81 connected via the tooth row 40, the cam plate 85 and the shaft member 6 is also prevented from rotating in the A and B directions, and the rotation of the arm means 81 is prohibited.
[0071]
The release means 59 is connected to a release lever 72 disposed on the lock means 58 so as to be swingable so as to release the frictional braking by moving the friction plate against the spring force of the lock means 58, and one end connected to the release lever 72. A wire 73 as a cord-like body, a grip member 74 which is connected to the other end of the wire 73 and is hanged down to the outside of the support column 2 so as to be operable, one end of the wire 73 and the other end of the support member And a coil spring 70 for pulling attached to the wire 2, and the wire 73 is wound around a turning pulley 75 rotatably supported by the column 2 and passes through a hole 76 formed in the column 2. It is arranged.
[0072]
The release means 59 is configured to swing the release lever 72 when the grip member 74 is pulled manually and the wire 73 is pulled as necessary during non-power supply to the electric motor 36 including a power failure. When the release lever 72 is swung by being pulled by the wire 73, the friction braking based on the spring force on the rotating shaft 37 of the electric motor 36 in the locking means 58 is released by the lever principle. Thus, the releasing means 59 releases the frictional braking in the locking means 58 during the non-power supply to the electric motor 36, and the spiral gear 39, the tooth row 40, the cam plate 85 on the rotating shaft 37 of the electric motor 36. And the prohibition of the rotation of the arm means 81 connected via the shaft member 6 is released. When the prohibition of the rotation of the arm means 81 by the locking means 58 is thus released, the arm means 81 can be manually rotated in the A and B directions so that the door 13 can be opened and closed manually. Become.
[0073]
The pin 73 attached to the support column 2 so that the wire 73 drawn out from the hole 76 can be wound or the grip member 74 moved to pull the wire 73 is attached to the support column 2 so as to be detachable. The release means 59 is further provided with a holding tool or the like, and the release state with respect to the locking means 58 can be maintained by winding the wire 73 around the pin or holding the grip member 74 on the holder. Good.
[0074]
In the flip-up type gate 1 described above, when the door is completely closed, the door 13 is substantially upright on the ground surface 55 as shown in FIGS. 1 and 2. In this state, the operator operates a switch (not shown) to supply power to the electric motor 36 and the locking means 58 to operate the electric motor 36, while the locking means 58 brakes the rotating shaft 37 of the electric motor 36. When the main arm member 8 is released in the A direction via the spiral gear 39, the tooth row 40, the cam plate 85, and the shaft member 6 by the rotation of the rotary shaft 37 by the operation of the electric motor 36, the main arm The connecting member 16 having the one end 14 connected to the member 8 via the shaft member 15 is dragged by the main arm member 8 while being rotated in the F direction with respect to the main arm member 8. The part 24 is guided by the guide passage 52 through the rotation of the roller 53 and is lifted. As a result, the auxiliary arm member 21 is pulled slightly toward the support column 2 as a whole, and the door 13 is pulled by this pulling. The door 13 is rotated in the D direction with respect to the other end portion 10 of the arm member 8. Therefore, the lower end 71 of the door 13 does not protrude forward as shown by the trajectory abc in FIG. After the main arm member 8 is rotated in the A direction from the fully closed position (position shown in FIGS. 1 and 2) to about 15 °, the main arm member 8 moves in the A direction. As the door 13 rotates, the lower end 71 of the door 13 slightly protrudes forward and rises along a trajectory cdef shown in FIG. The power supply to 36 and the locking means 58 is stopped, the operation of the electric motor 36 is stopped, and the locking of the rotating shaft 37 of the electric motor 36 by the locking means 58 is performed. 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.
[0075]
In order to change from the fully open door to the fully closed door, the main arm member 8 may be rotated in the B direction via the shaft member 6 by the reverse operation of the electric motor 36 by the operation of a switch (not shown) by the operator. Even when the door 13 is shifted to a fully closed door, the lower end 71 of the door 13 descends with a trajectory fedcba-a shown in FIG.
[0076]
In the flip-up type gate 1, the coil spring 96 generates a contraction elastic force that appropriately cancels the weight of the door 13 and the like, so that the meshing portion between the spiral gear 39 and the tooth row 40 in the fully closed door. Therefore, the door opening operation by the operation of the electric motor 36 can be performed without difficulty. When the arm means 81 is rotated in the A direction by the operation of the electric motor 36, the cam plate 85 is similarly rotated in the A direction as shown in FIG. The self-weight of the door 13 and the like is appropriately canceled out by the tensile elastic force of the coil spring 96 generated correspondingly to enable automatic opening without difficulty.
[0077]
In the flip-up type gate 1, since the contraction elastic force for rotating the arm means 81 in the A direction of the door 13 is generated only by the coil spring 96, temperature dependency can be eliminated as compared with the gas spring. As a result, it is possible to avoid a situation in which the opening and closing speeds differ due to load fluctuations of the electric motor 36.
[0078]
According to the flip-up type gate 1, the rotation of each unit amount detected by the unit rotation detecting means 28 that detects the rotation of each unit amount of the arm means 81 for every rotation of the unit means of the arm means 81. Since the operation of the electric motor 36 of the automatic arm rotation means 29 is stopped when the count value of the pulse corresponding to the number of times reaches a predetermined value, in other words, the rotation position of the arm means 81 Since the operation of the electric motor 36 is stopped based on the detected rotation position, the door 13 and the arm means 81 are completely closed and opened without contacting the ground and the stopper. It is possible to avoid the situation where the electric motor 36 which can realize the door reliably and thus causes anxiety to the operator is operated under a high load state, and uncomfortable clash when the door is completely closed and opened. Sound Was obtained. Moreover, may eliminate the reduction in the life of the rotation transmitting mechanism 60 including an electric motor 36 and the spiral gear 39 and teeth 40.
[0079]
According to the flip-up gate 1, the detection result from the predetermined position rotation detection means 33 is used to control the rotation of the arm means 81 based on the detection result from the predetermined position rotation detection means 33. As a result of being usable as the reference position, the rotation control of the arm means 81 by the unit rotation detection means 28 can be performed with reliability.
[0080]
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.
[0081]
In addition, according to the flip-up type gate 1, in order to stop the operation of the electric motor 36 after the rotation of the arm means 81 is decelerated, a large amount of electric power is not required for stopping the operation of the electric motor 36, and a small electric power is required. Thus, the complete closing and the complete opening can be performed accurately and reliably.
[0082]
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.
[0083]
According to the flip-up type gate 1, since the locking means 58 prohibits the automatic arm rotation means 29 from being de-energized to the electric motor 36 and the arm means 81 from being rotated, it is easy from the outside during non-power supply. Since the door 13 cannot be manually opened and closed, and the release means 59 is manually disposed on the support column 2, the lock means 58 can be released from the locked state by the release means 59 when a power failure or the like is required. The door 13 can be manually opened and closed from the inside.
[0084]
The release means 59 may be configured as shown in FIG. 12. The release means 59 shown in FIG. 12 is disposed in the support 77 and the housing 77 attached to the support column 2 in addition to the release lever 72. A slide knob 78 and a coil spring 79 disposed in the housing 77 and elastically biasing the slide knob 78 to return to the original position are provided. The housing 77 has an engagement hole 80. The slide knob 78 is formed integrally with the main body 110 slidably disposed in the housing 77 and one surface of the main body 110 and through the hole 111 of the housing 77. A knob 112 that protrudes outward and is disposed on the column 2, a protrusion 113 that is integrally formed on one surface of the main body 110, and a portion that is integrally formed on the other surface of the main body 110. Through the through hole 114 formed in the support 2 is provided with an engaging protrusion 115 to be engaged with the release lever 72.
[0085]
According to the release means 59 shown in FIG. 12, the release lever 72 can be swung via the engaging protrusion 115 by manually moving the knob 112 and sliding the slide knob 78 downward. Thus, the prohibition of the rotation of the arm means 81 can be released. In the release means 59 of FIG. 12, the protrusion 113 is inserted into the engagement hole 80 when the slide knob 78 is slid downward, so that the swinging state of the release lever 72 can be maintained. The release lever 72 is released from the swinging state by manually pressing the slide knob 78 toward the support column 2 via the knob 112 to extract the protrusion 113 from the engagement hole 80, and thereby rotating the coil spring. 79 can be performed by sliding the slide knob 78 upward.
[0086]
Further, the release means 59 may be configured as shown in FIGS. 13 and 14, and the release means 59 shown in FIGS. 13 and 14 includes a release lever 72 that protrudes out of the column 2 through the through hole 114, and a column. 2 and a leaf spring 118 which is fixed to the inner surface and bends and protrudes at the center, and the release lever 72 has a bifurcated portion 119 as a knob on its free end side, The leaf spring 118 is fixed to the inner surface of the column 2 with a screw or the like through between the bifurcated portions 119 disposed on the column 2. In the release means 59 of FIGS. 13 and 14, the prohibition of the rotation of the arm means 81 can be released by manually moving the bifurcated portion 119 and directly swinging the release lever 72. Since the base of the bifurcated portion 119 of the release lever 72 moves over the bent and protruded portion of the leaf spring 118 with the spring deformation of the leaf spring 118, the release lever 72 is engaged. The release lever 72 is directly and manually swung in the opposite direction to the above, and the bent portion of the leaf spring 118 with the spring deformation of the leaf spring 118 and the base of the bifurcated portion 119 By releasing the engagement, the swinging state of the release lever 72 can be released.
[0087]
