Description

【０００１】
【発明の属する技術分野】
本発明は、建物の竪樋から流下する雨水を集めるために用いられる集水装置に関し、特に、貯水容器の貯水量が一定量を超えた時に自動的に取水を停止する機構を備えた竪樋用集水装置に関するものである。
【０００２】
【従来の技術】
雨水は、建物の屋根面を流れて軒樋に入り、呼び樋から竪樋内を通過して排水される。近年、この雨水を有効利用するために、樋の途中に取水用の装置を設置することが提案されており、例えば、特開２００１−２０７４８５には、竪樋の中間部分に施工される取水器が開示されている。この取水器は、竪樋に嵌め込まれて使用される筒状体の側部に開口部を設け、該開口部にこれを開閉する取水板を回動自在に設けてなる。取水板は半円筒状で、基端部は竪樋の内部に差し込まれており、先端部には開いた状態で下方に傾斜する傾斜部が延設されている。
【０００３】
従って、竪樋から雨水を取り出したい時には、取水板を回動させて、開口部を開けることにより、取水板の基端部が竪樋を流れ落ちる雨水を受け、先端側の傾斜部から雨水を側方に導いて、容器等に貯水することができる。取水を停止する時には、取水板を元の位置に戻して、開口部を閉鎖する。これにより、大掛かりな装置を用いずに、竪樋からの取水が可能になる。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の装置は、ホースを接続してバケツ等の小容量の容器に簡易に貯水するためのもので、開口部を開閉する取水板をその度に手動で開閉操作しなければならない。このため、貯水槽等の比較的容量の大きい容器に適用しようとした場合には、容量を越えないように貯水量を監視して適当な時期に集水を停止する必要があり、放置すると、雨水が溢れてしまう。また、竪樋への取り付け場所が、取水板の手動操作が可能な部位に制限される不具合があった。
【０００５】
そこで、本発明は、容器の容量や雨量によらず、満水となった時に集水を自動的に停止する機構を備え、設置場所等が制約されたり、貯水量を監視する必要がなく、放置しても雨水が溢れてしまう懸念がない竪樋用集水装置を提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するための本発明請求項１の発明は、建物の壁面に固定される竪樋に介設されて、雨水を取水する竪樋用集水装置であって、竪樋の一部をなす筒状本体部と、該筒状本体部の側面に開口する集水口から側方へ延びて貯水容器に雨水を導く集水路と、上記集水口に回動自在に設けられて上記集水路を開閉する開閉部材と、上記開閉部材を上記集水路を閉じる方向に動作させて、上記貯水容器への導水を停止する集水停止手段とを備えている。
上記開閉部材は、上記集水路が開いた時に上記開閉部材の一端側が上記筒状本体部内に突出して上記集水路へ雨水を導くように構成され、上記開閉部材が通常状態で開となるように力を作用させる付勢部材が設けられる。
上記集水停止手段は、上記貯水容器内に配設したフロート部材と、一端が上記フロート部材に連結し、他端が上記開閉部材の上記一端側に連結されて上記フロート部材の動きを上記開閉部材に伝達する線状部材と、上記筒状本体部の側面に上記線状部材を外部に取り出すために設けられる貫通穴を有しており、上記貯水容器の貯水量が所定量を超えた時に上記フロート部材が上昇するのに伴い上記線状部材を介して上記開閉部材を上記集水路を閉じる方向に動作させるようになっている。
【０００７】
上記構成において、上記貯水容器が所定の貯水量を超えると、上記フロート部材が浮き上がり、貯水量が上昇するの伴って押し上げられる。これにより、上記上記線状部材を介して上記開閉部材が上記フロート部材方向に引っ張られ、上記集水路を閉じる。このように、本発明によれば、満水時に集水を自動的に停止することができるので、容器の容量や雨量に応じて貯水量を監視する必要がなく、放置しても雨水が溢れることがない。よって、貯水容器や設置場所等の選択の自由度が大きく、実用性の高い集水装置が得られる。
【０００８】
具体的には、上記開閉部材を、上記集水口に回動自在に設け、上記集水路を開いた時に上記開閉部材の一端側が上記筒状本体部内に回動して突出するようにしたので、上記集水路への導水が容易になる。そして、上記筒状本体部内に回動する上記開閉部材の一端側に上記線状部材を連結し、上記筒状本体部の側面に貫通穴を設けて、この貫通穴から上記線状部材を外部に取り出すようにすることで、上記貯水容器内に配設される上記フロート部材に、上記線状部材を容易に接続することができる。
さらに、上記開閉部材が通常状態で開となるように力を作用させる付勢部材を設けると、満水時以外には、上記集水路が開いた状態となる。例えば、上記貯水容器の雨水を使用して上記フロート部材が初期位置に戻ると、上記開閉部材が上記付勢部材によって開となるので、集水を自動的に再開することができる。
【０００９】
請求項２のように、上記貯水容器に、所定の貯水量を超えるまで上記フロート部材を支持する支持部材を設置することもできる。これにより、上記貯水容器が空の時に、上記フロート部材の重力が上記線状部材および上記開閉部材に作用しないようにすることができる。
【００１０】
請求項３のように、具体的には、上記竪樋を上下に分離し、上記竪樋用集水装置の上記筒状本体部が、上端が上側の竪樋の分離端部に嵌合される第１の筒状部と、下端が下側の竪樋の分離端部に嵌合される第２の筒状部とからなり、上記第１の筒状部と上記第２の筒状部をこれらの対向端で互いに嵌合せしめた構成することができる。この構成では、例えば、上記第１の筒状部を竪樋に外挿しておき、上記第２の筒状部を装着した後、両筒状部を嵌着することで、竪樋への施工が容易になり、実用的である。
【００１２】
請求項４のように、上記集水路に沿って上記線状部材を案内する案内部材を設けると、上記線状部材が容易に設置でき、また、上記集水停止手段による上記開閉部材の動作がスムーズにできる。
【００１３】
【発明の実施の形態】
以下、図面に基づいて本発明の第１の実施の形態を説明する。図１は、本発明の竪樋用集水装置の全体構成図で、集水装置１は、竪樋Ｔの一部をなす筒状本体部２を構成する第１の筒状部２１および第２の筒状部２２（以下、筒状部２１、２２という）と、筒状部２２から側方に延びる集水管３と、筒状部２２と集水管３の間を開閉するための開閉部材４とを有している。集水管３には、延長管５、６が接続されており、Ｔ字状に屈曲する延長管６の先端部は、貯水容器としての貯水槽７内に挿置されている。これら集水管３および延長管５、６が集水路を構成している。次に、装置各部の詳細を示す。
【００１４】
図２（ａ）、（ｂ）に示すように、竪樋Ｔは、集水装置１の取り付けのためにその一部を予め切除して上下に分離してあり、筒状部２１は、竪樋Ｔの上方の分離端部Ｔ１に下方から外挿され、筒状部２２は、やや小径とした下端部が、竪樋Ｔの下方の分離端部Ｔ２に嵌着されている。切除された竪樋Ｔの一部は、例えば、延長管５として利用することができる。筒状部２１と筒状部２２は、筒状部２１下端の小径部２３を、筒状部２２の上部開口内に嵌着することにより固定される。ここで、図３のように、筒状部２１の小径部２３には側面に突起２４が形成してあり、一方、筒状部２２の側面には、図４（ａ）、（ｂ）のように、該突起２４の対向位置に嵌合穴２５が設けられて、これら突起２４と嵌合穴２５が凹凸嵌合することにより位置固定されるようになっている（図２（ａ）、（ｂ）参照）。また、筒状部２１は下端縁２３ａを内向きに屈曲加工して、流下する雨水が中央に集まりやすいようにしている。
【００１５】
図４（ａ）、（ｂ）において、下方の筒状部２２には、側面に集水口２６となる開口が設けられるとともに、該集水口２６から側方に突出する集水菅３が一体に設けられている。集水菅３は、雨水が流れやすいように下方へ向けてやや傾斜させて設けられ、先端部３１は、延長管５を接続するためにやや肉厚の段付部となっている。集水菅３内には、下部内壁に沿う半円弧状断面の開閉部材４が回動自在に設置され、その一端は、筒状部２２の集水口２６と反対側の内側面近傍に達している。開閉部材４は、軸方向の中央部裏面に突設した軸孔４１に、軸部材４２を挿通して回動するようになっており、軸部材４２の両端は集水菅３の管壁に回動自在に固定されている。開閉部材４の集水菅３側の端部裏面には、付勢部材としての板状の重り部材４３が接合してあり、これによって、開閉部材４は、図に実線で示す通常状態において、集水口２６を開放する位置に付勢される。この時、開閉部材４の集水菅３内に位置する長さが、筒状部２２内に位置する長さよりも長くなるようにすると、より開方向に移動しやすくなる。好ましくは、付勢部材として重り部材４３に加えて、バネ部材４３´を、開閉部材４の裏面中央部と筒状部２２内壁面との間に設けるとよく、より確実に開位置に復帰させることができる。付勢部材をバネ部材４３´のみとすることもできる。
【００１６】
開閉部材４の筒状部２２側の端部裏面には、係止部４４が突設してあり、図２（ａ）のように、該係止部４４にワイヤ８または釣り糸等の線状部材の一端が連結されている。ワイヤ８の他端は、筒状部２２の側面に形成した貫通穴２７を通って外部へ導かれ、集水管３の先端部３１外表面に突設した案内部材としての案内穴３２と、延長管５、６の外表面に設置される複数の案内穴３２（図１参照）を通って、延長管６先端まで延びている。延長管５の案内穴３２は、着脱可能な案内部材３３に一体に設けてあり、案内部材３３は、例えば、所定長のバネ材を略Ｃ字状に曲げ加工してその開口部を開閉することにより、延長管５の外周に嵌着する構成とすることができる。延長管５を、竪樋Ｔの切除した一部で構成する場合には、このようにすると、案内穴３２の設置が容易になる。なお、集水路に沿って設ける案内穴３２の総数、設置間隔等は、必要に応じて任意に設定することができる。
【００１７】
図５（ａ）、（ｂ）のように、Ｌ字状の延長管６内は、屈曲部の下方に配設した隔壁６１によって、延長管５に接続される上部管６２とフロート部材８１が収容される下部管６３とに区画されている。隔壁６１は、集水路となる上部管６２に流入する雨水の流れが下り傾斜するように設置され、その下り側の端部に近い上部管６２側壁に、雨水を貯水槽７に導くための開口部６４が形成してある。一方、延長管６の下部管６３は、先端面（下端面）の対向端縁間に、フロート部材８１を支持する矩形板状の支持部材８３が架設されており、該支持部材８３中央に、側壁に固定した小径のＪ字管８２の先端が開口している。下部管６３内空間は、先端面に設けた連通口８４によって、貯水槽７内空間と連通している。これにより、貯水槽７の貯水量が多くなると、連通口８４を通って下部管６３内に貯水槽７の雨水が流入することになる。なお、Ｊ字管８２上方の、下部管６３上端部側面には、矩形の開口６５が形成してあり、導水時に、下部管６３内の空気抜き穴として機能する。
【００１８】
延長管５、６の管壁に沿って配設されたワイヤ８の先端は、案内部材となるＪ字管８２内を通って下部管６３内に至り、球状のフロート部材８１底部の留め具８１ａに連結されている。このように、Ｊ字管８２を用いて下部管６３への連結部にア−ルを設けていることで、管内を通るワイヤ８に縒りが生じにくくなり、ワイヤ８を介した開閉部材４の動きがスムーズになる。また、留め具８１ａを、自在に回転する猿環で構成すると、縒りや糸絡みを防止する効果が高く好ましい。Ｊ字管８２のア−ルの底部に水抜き用の穴８２ａを貫設してもよい。
【００１９】
ワイヤ８とフロート部材８１は、満水時に開閉部材４を閉じる集水停止手段を構成している。開閉部材４が集水口２６を開いている通常状態にある時、フロート部材８１は、支持部材８３上に支持されており、フロート部材８１の重力がワイヤ８を介して開閉部材４に作用しないようになっている。また、ワイヤ８は、開閉部材４が集水口２６を開放している状態で、閉鎖方向への力を受けず、緩みもほとんど生じない程度となるように、長さが調節されている。従って、貯水槽７が満水近くなり、連通口８４から下部管６３内に雨水が流入すると、流入量の上昇に伴い、フロート部材８１が浮き上がる。これにより、ワイヤ８が開閉部材４を下方に引っ張り、開閉部材４が回動して開口部２６を閉鎖する。ここで、下部管６３の管径はフロート部材８１よりやや大きい程度に設定してあり、フロート部材８１の横方向への動きが規制されて、速やかに下部管６３内を上昇するようになっている。
【００２０】
延長管６は、Ｊ字管８２の上端部に固定した取付部材７１によって、貯水槽７に取り付けられる。図６は取付部材７１の詳細図で、取付部材７１は、貯水槽７に取り付けるための凹部７２と、Ｊ字管８２に固定するための縦溝７４を有し、縦溝７４内にＪ字管８２を挟持してねじ締めするようになっている。貯水槽７へは、図１に示すように、凹部７２を貯水槽７の上縁部に嵌合し、側部に設けた取付穴７３にねじ部材７５を挿通して締め付けることにより固定される。なお、貯水槽７が、上端縁に内方に突出するフランジを有する形状である場合には、取付部材７１の上面に設けた縦溝７４´をＪ字管８２に固定し、凹部７２を、貯水槽７のフランジを上下から挟むように配置してねじ締めすることで、取り付けができる。
【００２１】
上記構成の竪樋用集水装置１を、竪樋Ｔに施工する手順は、以下のようにする。まず、集水装置１を取り付けるために、既存の竪樋Ｔの一部を筒状部２１、２２の取り付け長さより短く切除する（図２参照）。次いで、集水装置１の筒状部２１を、竪樋Ｔの上方の分離端部Ｔ１外周に下方から外挿する一方、筒状部２２の下端小径部を下方の分離端部Ｔ２内に嵌着する。この時、下端小径部を、分離端部Ｔ１下端縁に当接するまで上方に引き上げることで、筒状部２２の装着が可能になる。その後、筒状部２１を引き下げて、下端小径部を筒状部２２内に嵌着するとともに、突起２４と嵌合穴２５を凹凸嵌合させて固定する。さらに、筒状部２２の集水管３に延長管５、６を取り付け、延長管６を側部の取付部材７１によって、貯水槽７に取り付ける（図1 参照）。
【００２２】
なお、切除した既存の竪樋Ｔの一部を延長管５として用いれば、切除片を有効利用でき、廃棄物も生じない。また、ここでは、取り付けを容易にするために、延長管５、６を別体としたが、一体に設けることもできる。また、延長管５、６形状や長さ、貯水槽７への取り付け構造も、貯水槽７の位置や形状等に応じて任意に変更できる。
【００２３】
次に、本発明の竪樋用集水装置１の作動について説明する。
図１は、本発明の集水装置１を、竪樋Ｔに施工した直後の状態を示すもので、貯水槽７は空となっている。開閉部材４は、重り部材４３によって集水管３を開く位置にあり、開閉部材４の左半部が筒状部２２内に突出している。従って、雨天時に、屋根に降った雨水が竪樋Ｔ内を流下すると、筒状部２２内に突出する開閉部材４が雨水を受け、集水管３へ導く。この時、筒状部２１を下端縁が内方を向くように加工したので、雨水が効率よく、開閉部材４上に集水される。
【００２４】
これにより、図７に示すように、雨水が集水管３から延長管５、６を経て流れ、開口部６４から貯水槽７に導入される。貯水量が所定の量に達するまでは（満水前）、この状態が維持される。図８のように、貯水量が延長管６の下部管６３の連通口８４の位置を超えると（満水時）、連通口８４から下部管６３内に雨水が流入して、水位の上昇とともにフロート部材８１を押し上げる。これに伴い、フロート部材８１がワイヤ８を介して開閉部材４を回動させ、集水口２６を閉鎖する。これにより、雨水は集水管３に流入しなくなり、筒状部２２から竪樋Ｔ内を流下して、地上に排水される。貯水量が低下すると、フロート部材８１が再び下降し、開閉部材４は重り部材４３とバネ部材４３´の付勢力によって集水口２６を開放する初期位置に戻る。
【００２５】
このように、本実施の形態では、開閉部材４を常時開とする付勢手段と、満水となった時に自動的に開閉部材４を閉じる集水停止手段を設けて、開閉部材４が貯水量に応じて自動開閉するように構成したので、雨水を取水するために開閉部材４を手動で操作する必要がない。よって、貯水量を監視する必要がなくなり、放置しても雨水が溢れることがないので、雨水を効果的に貯留し有効に活用できる。また、既存の竪樋Ｔに容易に取り付けることができ、業者等に施工を依頼する必要がないので、経済的である。
【００２６】
なお、上記実施の形態では、球状のフロート部材８１を、延長管６の下部管６３内に支持する構成としたが、簡便のため、下部管６３を省略することもできる。この場合には、図９に示すように、Ｊ字管８２に代わる棒状の案内部材７６を設けて取付部材７１に固定し、案内部材７６に沿って複数配設した案内穴７７にワイヤ８を通してある。ワイヤ８の先端は、ペットボトル等からなるフロート部材８１´に固定されている。
【００２７】
この構成においても、貯水量が案内部材７２の下端に達すると、貯水量の上昇とともに、フロート部材８１´が押し上げられる。よって、同様に、ワイヤ８を介して開閉部材４を引っ張り、集水管３を閉じることができる。この構成では、フロート部材８１´を支持する支持部材がないが、この時、フロート部材８１´の重さに応じて開閉部材４に接合する重り部材４３やバネ部材４３´の付勢力を調整することで、開閉部材４に初期位置で閉鎖方向の力が作用しないようにすることが可能である。また、ペットボトル等をフロート部材８１´とすれば、廃物利用になり、交換も容易である。
【００２８】
また、本発明では、開閉部材４を手動で操作したり、貯水量を監視する必要がないので、図１０（ａ）のように、集水装置１を竪樋Ｔの上端部に施工して、通路を確保したり、図１０（ｂ）のように、竪樋Ｔの下端部に施工して、貯水槽７を地中に埋設することもできる。このように、本発明では、集水装置１の竪樋Ｔへの設置部位が制限されず、貯水槽７の設置場所も任意に選択することができる。また、延長管５の長さや形状を調整することで、既存の貯水槽への適用も容易にできる。

BACKGROUND OF THE INVENTION
The present invention relates to a water collecting apparatus used for collecting rainwater flowing down from a building fence, and in particular, a fence equipped with a mechanism that automatically stops water intake when the amount of water stored in a water storage container exceeds a certain amount. The present invention relates to a water collecting device.
[0002]
[Prior art]
Rainwater flows through the roof of the building, enters the eaves, and drains from the call through the fence. In recent years, in order to make effective use of this rainwater, it has been proposed to install a water intake device in the middle of a dredger. For example, Japanese Patent Laid-Open No. 2001-207485 discloses a water intake device constructed in the middle part of a dredger. Is disclosed. This water intake device is provided with an opening in a side portion of a cylindrical body that is used by being fitted in a bag, and a water intake plate for opening and closing the opening is provided in the opening so as to be rotatable. The intake plate has a semi-cylindrical shape, the base end portion is inserted into the inside of the ridge, and an inclined portion that inclines downward in an open state extends from the distal end portion.
[0003]
Therefore, when you want to take out rainwater from the dredge, rotate the intake plate to open the opening, so that the base end of the intake plate receives the rainwater that flows down the dredge, and the rainwater from the inclined portion on the front end side The water can be stored in a container or the like. When stopping the water intake, the water intake plate is returned to the original position and the opening is closed. As a result, water can be taken from the trough without using a large-scale device.
[0004]
[Problems to be solved by the invention]
However, the above-described conventional apparatus is for storing water in a small-capacity container such as a bucket by connecting a hose, and the intake plate for opening and closing the opening must be manually opened and closed each time. For this reason, when trying to apply to a container with a relatively large capacity such as a water storage tank, it is necessary to monitor the amount of stored water so as not to exceed the capacity and stop collecting water at an appropriate time. Rainwater overflows. In addition, there is a problem that the place where the water intake plate is attached is limited to a portion where manual operation of the intake plate is possible.
[0005]
Therefore, the present invention is provided with a mechanism for automatically stopping water collection when the water is full, regardless of the capacity of the container and the amount of rain, and there is no need to limit the installation location or monitor the amount of stored water. However, it is an object of the present invention to provide a water collecting apparatus for dredging that does not have a fear of overflowing rainwater.
[0006]
[Means for Solving the Problems]
A first aspect of the present invention for solving the above-described problems is a water collecting apparatus for water that is interposed in a wall fixed to a wall surface of a building and takes rainwater, and is a part of the wall. A cylindrical main body part, a water collecting path that extends laterally from a water collecting opening that opens to a side surface of the cylindrical main body part, and that guides rainwater to a water storage container; and the water collecting path that is rotatably provided at the water collecting opening. And an opening / closing member for opening and closing the water collecting means, and a water collection stopping means for operating the opening / closing member in a direction to close the water collecting passage to stop water introduction to the water storage container.
The opening / closing member is configured such that one end side of the opening / closing member projects into the cylindrical main body when the water collecting channel is opened to guide rainwater to the water collecting channel, and the opening / closing member is opened in a normal state. A biasing member for applying a force is provided.
The water collection stop means includes a float member disposed in the water storage container, one end connected to the float member , and the other end connected to the one end side of the opening / closing member to control the movement of the float member. A linear member that transmits to the member, and a through hole provided in the side surface of the cylindrical main body for taking out the linear member to the outside, and when the water storage amount of the water storage container exceeds a predetermined amount As the float member ascends, the opening / closing member is moved in the direction of closing the water collecting channel via the linear member.
[0007]
In the above configuration, when the water storage container exceeds a predetermined water storage amount, the float member floats and is pushed up as the water storage amount increases. Accordingly, the opening / closing member is pulled in the direction of the float member via the linear member, and the water collecting channel is closed. Thus, according to the present invention, since water collection can be automatically stopped when the water is full, it is not necessary to monitor the amount of water stored according to the capacity of the container and the amount of rain, and rainwater overflows even if left unattended. There is no. Therefore, a water collecting apparatus having a high degree of freedom in selecting a water storage container, an installation location, and the like and high practicality can be obtained.
[0008]
Specifically, the opening and closing member, disposed rotatably on the condensing Mizuguchi, since one end side of the opening and closing member when opening the condensing water channel was made to protrude rotates the cylindrical body portion, Water can be easily guided to the water collecting channel. And the said linear member is connected with the one end side of the said opening-and-closing member rotated in the said cylindrical main-body part, a through-hole is provided in the side surface of the said cylindrical main-body part, and the said linear member is outside from this through-hole. Thus, the linear member can be easily connected to the float member disposed in the water storage container.
Furthermore, when a biasing member that applies force so that the opening / closing member is opened in a normal state is provided, the water collecting channel is opened except when the water is full. For example, when the float member returns to the initial position using rainwater in the water storage container, the opening / closing member is opened by the biasing member, so that water collection can be automatically resumed.
[0009]
According to a second aspect of the present invention, a support member that supports the float member can be installed in the water storage container until a predetermined amount of water is exceeded. Thereby, when the water storage container is empty, the gravity of the float member can be prevented from acting on the linear member and the opening / closing member.
[0010]
More specifically, as described in claim 3, the basket is separated into upper and lower parts, and the cylindrical main body part of the water collecting apparatus for the bottle is fitted to the separation end of the bottle having an upper end. A first cylindrical portion and a second cylindrical portion whose lower end is fitted to a separation end portion of the lower flange, and the first cylindrical portion and the second cylindrical portion. Can be configured to be fitted to each other at their opposite ends. In this configuration, for example, the first tubular portion is extrapolated to the heel, and after mounting the second tubular portion, the two tubular portions are fitted, so that the construction to the heel is performed. Is easy and practical.
[0012]
If the guide member which guides the said linear member along the said water collection path is provided like Claim 4 , the said linear member can be installed easily, and operation | movement of the said opening-and-closing member by the said water collection stop means is Can be smooth.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall configuration diagram of a water collecting device for dredging according to the present invention. The water collecting device 1 includes a first tubular portion 21 and a first tubular portion 21 that form a tubular main body portion 2 that forms part of the dredging T. Two cylindrical portions 22 (hereinafter referred to as cylindrical portions 21 and 22), a water collecting pipe 3 extending laterally from the cylindrical portion 22, and an opening / closing member for opening and closing between the cylindrical portion 22 and the water collecting pipe 3. 4.

[0017]
As shown in FIGS. 5A and 5B, an L-shaped extension pipe 6 has an upper pipe 62 and a float member 81 connected to the extension pipe 5 by a partition wall 61 disposed below the bent portion. It is divided into a lower pipe 63 to be accommodated. The partition wall 61 is installed so that the flow of rainwater flowing into the upper pipe 62 serving as a water collecting channel is inclined downward, and an opening for guiding rainwater to the water storage tank 7 on the side wall of the upper pipe 62 near the end of the downstream side. A portion 64 is formed. On the other hand, the lower pipe 63 of the extension pipe 6 is provided with a rectangular plate-like support member 83 that supports the float member 81 between the opposed end edges of the front end face (lower end face). The tip of a small-diameter J-shaped tube 82 fixed to the side wall is open. The space in the lower pipe 63 communicates with the space in the water storage tank 7 through a communication port 84 provided on the distal end surface. As a result, when the amount of water stored in the water storage tank 7 increases, the rainwater in the water storage tank 7 flows into the lower pipe 63 through the communication port 84. In addition, a rectangular opening 65 is formed in the upper side surface of the lower pipe 63 above the J-shaped pipe 82, and functions as an air vent hole in the lower pipe 63 when water is introduced.
[0018]
The tips of the wires 8 disposed along the tube walls of the extension tubes 5 and 6 reach the lower tube 63 through the J-shaped tube 82 serving as a guide member, and the fastener 81a at the bottom of the spherical float member 81. It is connected to. In this way, by providing an alarm at the connecting portion to the lower tube 63 using the J-shaped tube 82, the wire 8 that passes through the tube is less likely to be twisted. The movement becomes smooth. In addition, it is preferable that the fastener 81a is composed of a monkey ring that freely rotates, because the effect of preventing twisting and thread entanglement is high. A drain hole 82a may be provided through the bottom of the alarm of the J-shaped tube 82.
[0019]
The wire 8 and the float member 81 constitute water collection stop means for closing the opening / closing member 4 when the water is full. When the opening / closing member 4 is in a normal state in which the water collection port 26 is open, the float member 81 is supported on the support member 83 so that the gravity of the float member 81 does not act on the opening / closing member 4 via the wire 8. It has become. Further, the length of the wire 8 is adjusted so that the wire 8 does not receive a force in the closing direction and hardly loosens in a state where the opening / closing member 4 opens the water collection port 26. Therefore, when the water storage tank 7 becomes almost full and rainwater flows into the lower pipe 63 from the communication port 84, the float member 81 rises as the inflow amount increases. As a result, the wire 8 pulls the opening / closing member 4 downward, and the opening / closing member 4 rotates to close the opening 26. Here, the pipe diameter of the lower pipe 63 is set to be slightly larger than that of the float member 81, and the movement of the float member 81 in the lateral direction is restricted, so that the inside of the lower pipe 63 is quickly raised. Yes.
[0020]
The extension pipe 6 is attached to the water storage tank 7 by an attachment member 71 fixed to the upper end portion of the J-shaped pipe 82. 6 is a detailed view of the attachment member 71. The attachment member 71 has a recess 72 for attachment to the water storage tank 7 and a longitudinal groove 74 for fixing to the J-shaped tube 82. The tube 82 is clamped and screwed. As shown in FIG. 1, the water tank 7 is fixed by fitting the recess 72 to the upper edge of the water tank 7, inserting a screw member 75 into the mounting hole 73 provided on the side, and tightening. . In the case where the water tank 7 has a shape having a flange protruding inward at the upper edge, the vertical groove 74 ′ provided on the upper surface of the mounting member 71 is fixed to the J-shaped tube 82, and the recess 72 is The water tank 7 can be attached by arranging and screwing the flange of the water tank 7 from above and below.
[0021]
The procedure for constructing the water collecting device 1 for dredging with the above configuration on the dredging T is as follows. First, in order to attach the water collecting apparatus 1, a part of the existing ridge T is cut out shorter than the attachment length of the cylindrical portions 21 and 22 (see FIG. 2). Next, the cylindrical portion 21 of the water collecting device 1 is extrapolated from below to the outer periphery of the separation end T1 above the trough T, while the lower end small diameter portion of the cylindrical portion 22 is fitted into the lower separation end T2. To wear. At this time, the cylindrical portion 22 can be mounted by pulling the lower end small diameter portion upward until it comes into contact with the lower end edge of the separation end portion T1. Thereafter, the cylindrical portion 21 is pulled down, the lower end small diameter portion is fitted into the cylindrical portion 22, and the protrusion 24 and the fitting hole 25 are fitted in an uneven manner and fixed. Further, the extension pipes 5 and 6 are attached to the water collecting pipe 3 of the cylindrical portion 22, and the extension pipe 6 is attached to the water storage tank 7 by the side attachment member 71 (see FIG. 1).
[0022]
In addition, if a part of the existing ridge T excised is used as the extension pipe 5, the excised piece can be used effectively and no waste is generated. Further, here, the extension pipes 5 and 6 are separated from each other for easy mounting, but they can be provided integrally. Further, the shape and length of the extension pipes 5 and 6 and the attachment structure to the water storage tank 7 can be arbitrarily changed according to the position and shape of the water storage tank 7.
[0023]
Next, the action | operation of the water collecting apparatus 1 for dredging of this invention is demonstrated.
FIG. 1 shows a state immediately after the water collecting device 1 of the present invention is applied to the trough T, and the water tank 7 is empty. The opening / closing member 4 is in a position to open the water collecting pipe 3 by the weight member 43, and the left half of the opening / closing member 4 protrudes into the cylindrical portion 22. Therefore, when rain water falls on the roof T in the rain, the opening / closing member 4 protruding into the cylindrical portion 22 receives rain water and guides it to the water collecting pipe 3. At this time, since the cylindrical portion 21 is processed so that the lower end edge faces inward, rainwater is efficiently collected on the opening / closing member 4.
[0024]
Accordingly, as shown in FIG. 7, rainwater flows from the water collection pipe 3 through the extension pipes 5 and 6 and is introduced into the water tank 7 through the opening 64. This state is maintained until the amount of stored water reaches a predetermined amount (before full water). As shown in FIG. 8, when the amount of stored water exceeds the position of the communication port 84 of the lower pipe 63 of the extension pipe 6 (when the water is full), rainwater flows into the lower pipe 63 from the communication port 84 and floats as the water level rises. The member 81 is pushed up. Accordingly, the float member 81 rotates the opening / closing member 4 via the wire 8 and closes the water collecting port 26. As a result, rainwater does not flow into the water collecting pipe 3, flows down from the cylindrical portion 22 through the eaves T, and is drained to the ground. When the amount of stored water decreases, the float member 81 descends again, and the opening / closing member 4 returns to the initial position where the water collection port 26 is opened by the urging force of the weight member 43 and the spring member 43 '.
[0025]
As described above, in the present embodiment, the biasing means that always opens the opening and closing member 4 and the water collection stop means that automatically closes the opening and closing member 4 when the water is full are provided. Therefore, it is not necessary to manually operate the opening / closing member 4 in order to take in rainwater. Therefore, there is no need to monitor the amount of stored water, and rainwater will not overflow if left unattended, so that rainwater can be effectively stored and used effectively. Moreover, since it can be easily attached to an existing bag T and it is not necessary to request construction from a contractor or the like, it is economical.
[0026]
In the above embodiment, the spherical float member 81 is supported in the lower pipe 63 of the extension pipe 6. However, the lower pipe 63 may be omitted for simplicity. In this case, as shown in FIG. 9, a rod-shaped guide member 76 instead of the J-shaped tube 82 is provided and fixed to the mounting member 71, and the wire 8 is passed through the guide holes 77 provided along the guide member 76. is there. The tip of the wire 8 is fixed to a float member 81 ′ made of a PET bottle or the like.
[0027]
Also in this configuration, when the water storage amount reaches the lower end of the guide member 72, the float member 81 ′ is pushed up as the water storage amount increases. Therefore, similarly, the open / close member 4 can be pulled via the wire 8 to close the water collecting pipe 3. In this configuration, there is no support member that supports the float member 81 ′. At this time, the biasing force of the weight member 43 and the spring member 43 ′ that are joined to the opening / closing member 4 is adjusted according to the weight of the float member 81 ′. Thus, it is possible to prevent a force in the closing direction from acting on the opening / closing member 4 at the initial position. Moreover, if a plastic bottle etc. is used as the float member 81 ', it will become waste utilization and replacement | exchange is easy.
[0028]
Moreover, in this invention, since it is not necessary to operate the opening-and-closing member 4 manually or to monitor the amount of stored water, the water collecting device 1 is constructed on the upper end of the ridge T as shown in FIG. It is also possible to secure the passage, or to construct the water tank 7 in the ground by constructing it at the lower end of the trough T as shown in FIG. 10 (b). Thus, in this invention, the installation site | part to the dredger T of the water collecting apparatus 1 is not restrict | limited, The installation location of the water storage tank 7 can also be selected arbitrarily. Further, by adjusting the length and shape of the extension pipe 5, it can be easily applied to an existing water tank.
