Description

【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、電動モータへの給電のために100ボルトの商用電源から跳ね上げ式門扉への絶縁工事を含む電源ケーブルの設置工事を要して思わぬ出費が嵩む上に、跳ね上げ式門扉の設置後も、開扉動作による電力消費を招来してランニングコストも無視できなくなると共に、100ボルトの商用電源を用いる場合には、落雷等の何らかの原因による停電等で扉を開閉できないことも生じ得る。
【0004】
また、電動モータにより自動的にアームを回動させる跳ね上げ式門扉において、停電等で扉を開閉できない場合には、手動で開閉できることが好ましいのであるが、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】
加えて、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と共に電力消費が多くなる上に、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、100ボルトの商用電源からの電源ケーブルの設置工事を不要にでき、設置後も、ランニングコストを大幅に低減できると共に、100ボルトの商用電源の停電等に左右されないで開閉できる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、非給電中には外からは容易に手動開閉できない上に、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。
【0010】
本発明の更に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、省電力化を果たし得る上に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。
【0011】
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。
【0012】
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。
【0013】
【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、支柱、アーム手段及び扉のうちの少なくとも一つに太陽光を受容するように設けられていると共に、自動アーム回動手段の電動モータを作動させる電力を発生する太陽電池とを具備している。
【0014】
第一の態様の跳ね上げ式門扉によれば、自動アーム回動手段の電動モータを作動させる電力を発生する太陽電池を具備し、しかも、この太陽電池が支柱、アーム手段及び扉のうちの少なくとも一つに設けられているために、100ボルトの商用電源からの電源ケーブルの設置工事を不要にでき、設置後も、太陽エネルギを用いるためにランニングコストを大幅に低減できると共に、100ボルトの商用電源の停電等に左右されないで扉を開閉できる。なお、本発明においては、24ボルト以下の低電圧で作動する直流電動モータを用いることにより、高電圧において必要とされる絶縁工事を必要としない上に、直流での簡単な制御を行い得るので好ましい。
【0015】
本発明の第二の態様の跳ね上げ式門扉は、第一の態様の跳ね上げ式門扉において、太陽電池により発生された電力を蓄える蓄電池を更に具備しており、ここで、自動アーム回動手段の電動モータには、太陽電池及び蓄電池のいずれか一方から給電されるようになっている。
【0016】
第二の態様の跳ね上げ式門扉によれば、太陽エネルギが得られない場合にも、太陽電池により予め得られた蓄電池の電力でもって自動アーム回動手段の電動モータを作動させることができ、太陽エネルギを無駄なく効果的に利用できる。なお、自動アーム回動手段の電動モータへの給電は、太陽電池から直接的に行う一方、夜、雨天等で太陽電池から所定の電力が得られない場合に、蓄電池から行うようにしてもよいが、これに代えて、太陽電池から充電される蓄電池から直接的に行うようにしても、更には、太陽電池及び蓄電池から並列的に行うようにしてもよい。
【0017】
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、蓄電池は支柱内に配されており、太陽電池は、内部に蓄電池が配された支柱の天井面に設置されている。
【0018】

【0019】
本発明の第四の態様の跳ね上げ式門扉は、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、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。
【0020】
第四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、電動モータを作動させるだけの所定の電力が得られない場合等において、必要な際には容易に内側から手動開閉できる。
【0021】
本発明の第五の態様の跳ね上げ式門扉では、第四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。
【0022】
第四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六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。
【0023】
解除手段は、本発明の第七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、本発明の第八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。
【0024】
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。
【0025】
本発明の第九の態様の跳ね上げ式門扉では、上記の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、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。
【0026】
第九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。
【0027】
本発明の第十の態様の跳ね上げ式門扉は、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、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。
【0028】
第十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十一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。
【0029】
第十一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、省電力化を果たし得る上に電動モータ及び伝達機構等の寿命の低下をなくし得る。
【0030】
本発明の第十二の態様の跳ね上げ式門扉は、第十又は第十一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。
【0031】
第十二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。
【0032】
制御手段は、本発明の第十三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、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、本発明の第十五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。
【0033】
第十三及び第十五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。
【0034】
また第十三から第十六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。
【0035】
また制御手段は、本発明の第十七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、本発明の第十八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、本発明の第十九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、本発明の第二十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。
【0036】
第十七及び第十九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。
【0037】
弾性力付与手段は、好ましい例では本発明の第二十一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。
【0038】
第二十一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。
【0039】
アーム手段は、好ましい例では本発明の第二十二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。

【0041】
連結案内手段は、本発明の第二十三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、本発明の第二十四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、本発明の第二十五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。
【0042】
第二十三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、第二十四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、第二十五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。
【0043】
本発明の第二十六の態様の跳ね上げ式門扉では、第二十二から第二十五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。
【0044】
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、第二十七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。
【0045】
本発明の第二十二から第二十七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、その第二十八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。
【0046】
また第二十二から第二十八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、その第二十九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。
【0047】
更に第二十二から第二十九のいずれかの態様の本発明の跳ね上げ式門扉では、好ましくはその第三十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。
【0048】

【0049】
第三十一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。
【0050】
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。

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。
【0054】
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、太陽電池121、蓄電池122、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く、また、太陽電池121及び蓄電池122と同等の太陽電池及び蓄電池を支柱3側にも設けて、支柱3側の自動アーム回動手段の電動モータにこれら太陽電池及び蓄電池から給電してもよい。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。
【0055】
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。
【0056】
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。
【0057】
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。
【0058】
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。
【0059】
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。
【0060】
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。
【0061】
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。
【0062】
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。
【0063】
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。
【0064】
直流24ボルトで作動する可逆の直流電動モータ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。
【0065】
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。
【0066】
直流出力電圧24ボルトの蓄電池122は支柱2内に配されており、多数のソーラーセルを含んだソーラーパネルからなる太陽電池121は、内部に蓄電池12が配された支柱2の天井面123に設置されており、発生した電力を蓄電池122に供給して当該蓄電池122を充電するようになっている。電動モータ36は、制御手段34の制御下で、太陽電池121及び蓄電池122のいずれか一方、本例では太陽電池121によって充電された蓄電池122から給電されて作動するようになっている。
【0067】
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。
【0068】
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。
【0069】
電動モータ36と同様に蓄電池122から給電されて作動する制御手段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への蓄電池122による給電を停止(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。
【0070】
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、蓄電池122からの電動モータ36への給電を行わせ、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、蓄電池122からの電動モータ36への給電を停止(非給電)するようになっている。
【0071】
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、蓄電池122から電動モータ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閉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、蓄電池122からの電動モータ36への給電を停止(非給電)するようになっている。
【0072】
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。
【0073】
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。
【0074】
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。
【0075】
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。
【0076】
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。
【0077】
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蓄電池122から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。
【0078】
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。
【0079】
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。
【0080】
解除手段59は、電動モータ36を作動させるだけの所定の電力が得られない場合等の電動モータ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。
【0081】
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。
【0082】
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。
【0083】
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。
【0084】
跳ね上げ式門扉1では、電動モータ36を作動させる電力を発生する太陽電池121を具備し、しかも、太陽電池121が支柱2に設けられているために、100ボルトの商用電源からの電源ケーブルの設置工事を不要にでき、設置後も、太陽エネルギを用いるためにランニングコストを大幅に低減できると共に、100ボルトの商用電源の停電等に左右されないで扉13を開閉でき、また、太陽エネルギが得られない場合にも、太陽電池121により予め得られた蓄電池122の電力でもって電動モータ36を作動させることができ、太陽エネルギを無駄なく効果的に利用でき、蓄電池122が支柱2内に配されており、太陽電池121が支柱2の天井面123に設置されているために、蓄電池122と太陽電池121とに関する電気配線を一つの支柱において行うことができ、設置作業を簡単にできて設置コストの低減を図ることができる上に、支柱2が通常屋外に配置されるために太陽光を効果的に利用できる。
【0085】
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。
【0086】
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。
【0087】
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、省電力化を果たし得る上に電動モータ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。
【0088】
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。
【0089】
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。
【0090】
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。
【0091】
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。
【0092】

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]
In addition, when an electric motor is further added to the flip-up type gate described in the above publication, and the arm is automatically rotated by the electric motor to automatically open and close the door, the electric motor Power supply, including insulation work from a 100-volt commercial power supply to the flip-up gate for power supply to the power supply, and unexpected expenses increase, and even after the flip-up gate is installed, the door opens. Power consumption due to operation is incurred and the running cost cannot be ignored. When a commercial power supply of 100 volts is used, the door may not be opened or closed due to a power failure due to a lightning strike or the like.
[0004]
Moreover, in the flip-up type gate that automatically rotates the arm by the electric motor, it is preferable that the door can be manually opened / closed when the door cannot be opened / closed due to a power failure or the like. In this case, a third party who has nothing to do can easily be manually opened and closed from the outside, and such a gate used as a gate of a car garage or the like becomes extremely useless.
[0005]
In addition, in the case of an automatic flip-up type gate, if the operation of the electric motor is stopped after contact with the ground or stopper of the door or arm in order to ensure complete closing and complete opening, The electric motor seems to have been operated in a high load state after the contact until the operation is stopped, which causes anxiety to the operator, shortens the life of the electric motor and increases power consumption. An excessive force is applied to the rotation transmission mechanism that transmits the rotation of the output rotation shaft to the arm. This also shortens the life of the rotation transmission mechanism, and in addition, the inertia of the door or the like due to the weight of the arm or the like. There is a risk that loud noise is generated due to abrupt contact with a stopper or the like.
[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 its object is to eliminate the need for installation work of a power cable from a commercial power supply of 100 volts, and to significantly reduce running costs even after installation. Another object of the present invention is to provide an automatic flip-up gate that can be opened and closed without being affected by a power failure of a commercial power supply of 100 volts.
[0009]
Another object of the present invention is to provide an automatic flip-up gate that cannot be easily manually opened and closed from the outside during non-power feeding and can be easily manually opened and closed when necessary. It is in.
[0010]
Still 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, To provide a flip-up type gate that can eliminate a crashing into a stopper and the like, can eliminate an unpleasant crashing noise, can save power, and can eliminate a decrease in the life of an electric motor and a transmission mechanism. It is in.
[0011]
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.
[0012]
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.
[0013]
[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.

[0014]
According to the flip-up type gate of the first aspect, the solar cell includes a solar cell that generates electric power for operating the electric motor of the automatic arm rotation unit, and the solar cell is at least one of the support column, the arm unit, and the door. Because it is installed in one, the installation work of the power cable from the 100 volt commercial power supply can be made unnecessary, and even after the installation, the running cost can be greatly reduced due to the use of solar energy. The door can be opened and closed without being affected by a power failure. In the present invention, since a DC electric motor that operates at a low voltage of 24 volts or less is used, insulation work required at a high voltage is not required, and simple control at a direct current can be performed. preferable.
[0015]
The flip-up type gate of the second aspect of the present invention is the flip-up type gate of the first aspect, further comprising a storage battery for storing electric power generated by the solar cell, wherein the automatic arm turning means The electric motor is supplied with power from either a solar battery or a storage battery.
[0016]
According to the flip-up type gate of the second aspect, even when solar energy cannot be obtained, the electric motor of the automatic arm turning means can be operated with the power of the storage battery obtained in advance by the solar battery, Solar energy can be used effectively without waste. The power supply to the electric motor of the automatic arm rotating means is directly performed from the solar battery, but may be performed from the storage battery when predetermined power cannot be obtained from the solar battery at night or rainy weather. However, instead of this, it may be performed directly from a storage battery charged from a solar battery, or may be performed in parallel from a solar battery and a storage battery.
[0017]
Preferably, like the flip-up type gate of the third aspect of the present invention, the storage battery is disposed in the support column, and the solar cell is installed on the ceiling surface of the support column in which the storage battery is disposed.
[0018]
According to the flip-up type gate of the third aspect, the electrical wiring relating to the storage battery and the solar battery can be performed on one support column, the installation work can be simplified and the installation cost can be reduced.
[0019]

[0020]
According to the flip-up type gate of the fourth aspect, since the locking means prohibits the power supply of the automatic arm rotation means to the electric motor and prohibits the rotation of the arm means, it is easy from the outside during the non-power supply. When the door cannot be opened and closed manually, and the release means is manually arranged on the support column, when it is not possible to obtain the required power to operate the electric motor, it can be easily Can be manually opened and closed.
[0021]
In the flip-up type gate of the fifth aspect of the present invention, in the flip-up type gate of the fourth aspect, the automatic arm rotating means includes a rotation transmission mechanism for transmitting the rotation of the rotating 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.
[0022]
The locking means in the flip-up gate of the fourth 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 sixth aspect of the present invention. The brake to the rotating shaft of the electric motor is released.
[0023]
The release means includes a grip member arranged on the support like the flip-up type gate of the seventh 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 eighth aspect of the present invention, it has a knob portion arranged on the support column, and it is prohibited to turn the arm means by moving the knob portion. You may come to cancel.
[0024]
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.
[0025]
In the flip-up gate according to the ninth aspect of the present invention, in the flip-up gate according to any one of the fourth to sixth aspects, the elastic force applying means includes a coil spring, which is substantially An elastic force in the direction in which the door is flipped up is applied to the arm means by a coil spring.
[0026]
According to the flip-up type gate of the ninth 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.
[0027]
The flip-up gate according to the tenth aspect of the present invention is the flip-up gate according to any one of the fourth to ninth 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.
[0028]
The control means in the flip-up type gate of the tenth aspect is preferably unit-rotated by turning the arm means in the direction of raising or lowering the door, like the flip-up type gate of the eleventh 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 detection means reaches a predetermined value.
[0029]
According to the flip-up type gate of the eleventh aspect, every unit amount detected by the unit rotation detecting means for detecting the rotation of each unit amount of the arm means for every 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 rotations reaches a predetermined value, in other words, the rotation position of the arm means is detected and this is detected. Since the operation of the electric motor is stopped based on the detected rotation position, complete closing and complete opening can be reliably realized without bringing the door and arm means into contact with the ground and stoppers. Thus, it is possible to avoid a situation in which the electric motor that causes anxiety to the operator is operated under a high load state, and it is possible to eliminate unpleasant crushing noise when the door is fully closed and fully opened, Can save power It may eliminate the reduction in the life of the electric motor and transmission mechanism.
[0030]
The flip-up gate of the twelfth aspect of the present invention is the flip-up gate of the tenth or eleventh aspect, wherein the arm means is rotated to a predetermined position between the fully open door and the fully closed door. Predetermined position rotation detection means for detecting 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.
[0031]
According to the flip-up type gate of the twelfth 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 result of being usable as the reference position, the rotation control of the arm means by the unit rotation detection means can be performed with reliability.
[0032]
As in the flip-up type gate of the thirteenth aspect of the present invention, the control means operates 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 rotation of the arm means is decelerated by controlling the arm means, as in the flip-up type gate of the fourteenth aspect of the present invention, in the rotation of the arm means in the direction in which the door is raised, After the detection result from the position 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 if it is configured to be operated, it is electrically operated based on the detection result from the predetermined position rotation detecting means in the rotation of the arm means in the door lowering direction, like the flip-up type gate of the fifteenth aspect of the present invention. Rotate arm means by controlling motor operation Even in the case of speeding up, and like the flip-up type gate of the sixteenth aspect of the present invention, the detection result from the predetermined position rotation detection means in the rotation of the arm means in the downward direction of the door. After the occurrence, the operation of the electric motor of the automatic arm rotation means may be stopped when the number of rotations per unit amount detected by the unit rotation detection means reaches a predetermined value.
[0033]
According to the flip-up type gate of the thirteenth and fifteenth aspects, the operation of the electric motor can be stopped after the rotation of the arm means is decelerated. Therefore, it is possible to accurately and reliably perform the complete closing and the complete opening with a small electric power.
[0034]
Further, according to the flip-up type gate of the thirteenth to sixteenth aspects, after the detection result from the predetermined position rotation detection means occurs, the rotation of the arm means is decelerated or the operation of the electric motor is stopped. In addition, deceleration or deactivation is ensured.
[0035]
Further, the control means, like the flip-up type gate of the seventeenth aspect of the present invention, for each unit amount detected by the unit rotation detecting 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 eighteenth 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 is stopped, as in the flip-up type gate of the nineteenth 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 twentieth 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.
[0036]
According to the flip-up gates of the seventeenth and nineteenth 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 stopping the operation of the electric motor. Therefore, it is possible to accurately and reliably perform complete closing and complete opening with small electric power.

[0060]
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.
[0061]
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.
[0062]
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.
[0063]
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.
[0064]
A reversible DC electric motor 36 that operates at 24 volts DC is fixed to the substrate 104 via a bracket 56, a gear case 38 is attached to the substrate 104, and the rotating shaft 37 is spiraled via a connector 57. The gear 39 is connected.
[0065]
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.
[0066]
A storage battery 122 with a DC output voltage of 24 volts is arranged in the support column 2, and a solar battery 121 composed of a solar panel including a large number of solar cells is installed on the ceiling surface 123 of the support column 2 in which the storage battery 12 is arranged. The generated electric power is supplied to the storage battery 122 to charge the storage battery 122. The electric motor 36 is operated under the control of the control means 34, powered by one of the solar battery 121 and the storage battery 122, in this example, the storage battery 122 charged by the solar battery 121.
[0067]
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.
[0068]
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.
[0069]
Like the electric motor 36, the control means 34 that is operated by being supplied with power from the storage battery 122 is a computer or the like, and is unit rotated by turning the arm means 81 in the upward and downward directions of the door 13, that is, in the A and B directions. When the number of rotations per unit amount detected by the detection unit 28 reaches a predetermined value, the power supply by the storage battery 122 to the electric motor 36 of the automatic arm rotation unit 29 is stopped (non-powered). The arm means 81 is controlled by controlling the operation of the electric motor 36 based on the detection result from the predetermined position rotation detection means 33 in the rotation of the arm means 81 in the A and B directions. The rotation of the motor is decelerated.
[0070]
That is, the control means 34 is a completely closed door shown in FIGS. 1 and 2, and when the switch (not shown) attached to the support column 2 or the like is pressed by the operator, the control means 34 supplies power to the electric motor 36 from the storage battery 122. The electric motor 36 is operated so as to rotate the rotating shaft 37 at, for example, 1700 rpm to 1400 rpm, whereby arm means in the A direction via the rotating shaft 37, spiral gear 39, tooth row 40, cam plate 85 and shaft member 6. 81 is rotated so that the door 13 is flipped up, and after the switch is pressed, the pulse indicating the rotation for each unit amount from the unit rotation detecting unit 28 is counted while the arm unit 81 is rotating in the A direction. Next, a detection result indicating that the arm means 81 has been rotated from the fully opened door to a position 10 ° before the angle is generated from the predetermined position rotation detecting means 33 and this is detected. When the output result is received from the predetermined position rotation detection means 33, the electric motor 36 is operated so as to rotate the rotating shaft 37 by decelerating at, for example, 300 rpm to 500 rpm, and then a pulse indicating the number of rotations per unit amount. When the counted value reaches a value set in advance as the rotational position of the arm means 81 that is fully opened, power supply from the storage battery 122 to the electric motor 36 is stopped (non-power supply) to stop the operation of the electric motor 36. ).
[0071]
10 and 11, when the lower switch 71 of the door 13 is in the fully open state where the position f is shown in FIG. 10 and FIG. The electric motor 36 is reversely operated so that the electric motor 36 is fed to rotate the rotary shaft 37 at, for example, 1700 rpm to 1400 rpm, whereby the rotary shaft 37, the spiral gear 39, the tooth row 40, the cam plate 85, and the shaft member 6 are operated. The arm means 81 is rotated in the B direction through the door to lower the door 13, and after the switch is pressed, the unit means from the unit rotation detecting means 28 during the rotation of the arm means 81 in the B direction. The above-mentioned count value is continuously subtracted with a pulse indicating movement, and the arm means 81 is rotated from the fully closed door to a position 15 ° before the angle. When the electric motor 36 is actuated so as to rotate the rotating shaft 37 at a reduced speed of, for example, 300 rpm to 500 rpm, the number of rotations per unit amount of the arm means 81 is indicated. An electric motor from the storage battery 122 is used to stop the operation of the electric motor 36 when the pulse count value becomes zero. Power supply to 36 is stopped (non-power supply).
[0072]
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.
[0073]
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. .
[0074]
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.
[0075]
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.
[0076]
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.
[0077]
The locking means 58 includes an electromagnetic clutch having an electromagnet, a spring, a movable iron piece, a friction plate, and the like. The locking means 58 supplies power to the electric motor 36 of the automatic arm rotation means 29 and supplies power from the storage battery 122 to the electromagnet. The electromagnetic force is generated, and the movable iron piece and the friction plate are moved against the spring force of the spring with this electromagnetic force to release the braking to the rotating shaft 37 of the electric motor 36 and to enable the rotating shaft 37 to rotate. When the automatic arm rotating means 29 is not supplied with power to the electric motor 36, the electromagnet is also supplied with power, and the rotation shaft 37 of the electric motor 36 is subjected to friction braking of the friction plate based on the spring force of the spring to inhibit the rotation of the rotation shaft 37. It is like that.
[0078]
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.
[0079]
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.
[0080]
The release means 59 is configured such that when the grip member 74 is pulled manually and the wire 73 is pulled when necessary during the non-power supply to the electric motor 36 such as when the predetermined electric power for operating the electric motor 36 cannot be obtained. The release lever 72 is swung. 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.
[0081]
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.
[0082]
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.
[0083]
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.
[0084]
The flip-up type gate 1 includes a solar cell 121 that generates electric power for operating the electric motor 36, and the solar cell 121 is provided on the column 2, and therefore the power cable from a commercial power supply of 100 volts is used. Installation work can be dispensed with, and after installation, solar energy can be used to significantly reduce running costs, and the door 13 can be opened and closed without being affected by a 100-volt commercial power failure.
