Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、一方の水槽から他方の水槽へ水を供給するとき等に使用されるサイフォン管に関するものである。
【０００２】
【従来の技術】
従来、金魚、熱帯魚等の観賞魚が飼われる水槽であって水位の高い水槽から水位の低い水槽へ水を供給する場合、ポンプなど電気器具を使用する必要がないサイフォン管が使用されている(例えば、特許文献１参照。)。
【０００３】

実開平６−６０３４５号公報（第１−２頁、図１）
【０００４】
【発明が解決しようとする課題】
前記特許文献１のサイフォン管は、逆Ｕ字状をなし水槽の一側壁を跨ぐようにして配設されると共に開放した両先端面が下向きに設けられているので、例えば、供給する側の水槽の水が減ってその水位が前記サイフォン管の先端面より下方にくると、サイフォン管内の水も自然と抜け出て水の供給が停止してしまう。そこで、一度水の切れたサイフォン管を再び働かすには、前記供給する側の水槽の水を増し、サイフォン管全体を水中に漬けそのサイフォン管内の空気を抜くなど面倒な作業を強いられ手間が掛かる。また、このためサイフォンを働かせて一方の水槽の水を他方の水槽へ供給し始めると、前記のようにサイフォン管を再び働かすに手間が掛かることから、水槽内の手入れのため途中で一時的に止めることが難しく、使い勝手が悪いという課題がある。
【０００５】
そこで、本発明は上記課題に鑑みてなされたもので、液槽内の液体から引き出しても、起立した状態では液体が留まり、そのまま液槽の一側壁に跨らせるようにして設置すれば、すぐにサイフォンが働いて他方の液槽へ簡単に液体の供給ができ、また、他方の液槽への液体の供給と停止とが自在に切替えできるといった極めて使い勝手の良いサイフォン管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】
かかる目的を達成するため、本発明に係るサイフォン管は、両先端面が開放すると共に該両先端面より上方で適宜形状に曲げられる管本体と、前記管本体の両先端部に設けられ前記先端面を介して前記管本体と連通すると共に上面が開口し、前記上面開口が前記管本体の先端面の高さより上方に位置する液溜め部と、からなり、前記管本体の各先端面は互いに他方側の前記液溜め部の上面開口より下方に位置するように設定され、前記管本体内と前記両液溜め部内とに液体を充填して起立させたとき、前記管本体内の液体が自然と抜け出ないようにした。
【０００７】
また、他の構成として、両先端面が開放する管本体の両先端部を該各先端面が上方を向くようにして曲げ、また、前記管本体の両先端面より上方を適宜形状に曲げてなり、前記各先端部の先端面は互いに他方側の前記先端部の最下部より上方に位置するように設定され、前記管本体内に液体を充填して起立させたとき、前記管本体内の液体が自然と抜け出ないようにした。
【０００８】
更に、他の構成として、両先端面が開放すると共に該両先端面より上方で適宜形状に曲げられる管本体と、前記管本体の一方の先端部に設けられ、その先端面を介して前記管本体と連通すると共に上面が開口し、前記上面開口が前記管本体における一方の先端部の先端面より上方に位置する液溜め部と、からなり、前記管本体における他方の先端部はその先端面が上方を向くようにして曲げられ、前記管本体における液溜め部内の一方の先端部の先端面は前記他方の曲げられた先端部の先端面よりも下方に位置し、かつ、前記管本体の他方の曲げられた先端部における最下部は前記液溜め部の上面開口より下方に位置するように設定され、前記管本体内に液体を充填して起立させたとき、前記管本体内の液体が自然と抜け出ないようにした。
【０００９】
これにより、例えば、サイフォン管内に液体が留まったままで、その一端部を液槽の液体内に漬ければ、そのときから自然とサイフォンが働いて他方の液槽への水の供給ができることになり、簡単で時間が掛からない。また、途中で液槽の液体内から自在に出し入れしても、常にサイフォンが働くことになるので、使い勝手が良い。
【００１０】
サイフォン管が大型の場合は、両先端面が開放すると共に両先端部を該各先端面が上方を向くようにして曲げ、また、前記両先端面より上方が適宜形状に曲げられる管本体と、前記管本体の最上部に設けられ液体を注入するための供給口と、前記両先端部の先端面及び前記供給口にそれぞれ開閉可能に取着される開閉部材と、からなり、前記両先端部の各先端面は互いに他方側の先端部の最下部より上方に位置するように設定され、前記管本体内に液体を充填して供給口を閉めると共に起立させた状態で両先端面を開けたとき、前記管本体内の液体が自然と抜け出ないようにした。
【００１１】
このサイフォン管では、起立させた状態で、両先端部の先端面を開閉部材により塞いでおき、最上部に位置する供給口を開けその供給口からサイフォン管内に液体を流し込み一杯に充填する。そして、前記供給口を開閉部材により密閉した後に、前記両先端部の先端面の開閉部材を取り外してこれら上面開口を開ける。この状態で、隣接する両液槽内にそれぞれ先端部を配置し一方の先端面を液体内に漬ける。これにより、サイフォンが働いて液体の供給が行なえるようになる。
【００１２】
【発明の実施の形態】
以下、本発明に係るサイフォン管の実施の形態を図面に基づき説明する。図１乃至４は第一実施の形態に係るものであって観賞魚用の水槽に使用した場合、図５は第二実施の形態に係るもの、図６は第三実施の形態に係るもの、図７乃至図９は第四実施の形態に係るものであって生簀に使用した場合、更に、図１０は第五実施の形態に係るものであって屋外で水はけが悪く大量の雨水が溜まるような場所に使用した場合をそれぞれ示す。
【００１３】
図１は第一実施の形態に係るサイフォン管の斜視図、図２は同縦断正面図である。このサイフォン管Ａ１は、例えば、合成樹脂材により成形されるが、他に金属製、ガラス製またはセラミックス製であっても良い。このサイフォン管Ａ１は、両先端面２が開放される円筒から成形され、中央の横管部３とその両端部に接続される縦管部４，４とにより正面門型に成形される管本体１と、該管本体１の先端部１ａである前記両縦管部４，４の下端部に、各縦管部４と連通するようにして設けられ上面が開口５する液溜め部６，６と、からなる。前記横管部３がほぼ２３０ｍｍ、各縦管部４がほぼ２００ｍｍの寸法を有し、管本体１の内径はほぼ１５ｍｍの寸法を有する。また、前記横管部３を水平に保持したとき、管本体１の両先端面２となる両縦管部４，４の下端面は同じ高さ位置にあり、前記両液溜め部６，６の上面開口５，５も同一高さの位置にある。前記横管部３の一側上面に空気抜き孔３０が開設され、この空気抜き孔３０にゴム製の栓３１が抜脱自在に嵌入されている。
【００１４】
前記各液溜め部６は、有底筒体からなり、縦管部４の外周面に放射状に突設されるリブ７によりしっかりと固定され、各縦管部４の先端面２が液溜め部６内に介入することになる。しかも、前記管本体１の各先端面２，２は互いに他方側の前記液溜め部６，６の上面開口５より下方に位置するように設定されている。これにより、前記管本体１内と前記両液溜め部６，６内とに液体である水Ｗを充填して起立させたとき、前記各縦管部４の先端面２が各液溜め部６の水Ｗ内に漬かり、常態では前記管本体１内の水Ｗが自然と抜け出ることはない。
【００１５】
第一実施の形態に係るサイフォン管Ａ１は上記構成からなる。図示は省略するが、使用する前にサイフォン管Ａ１全体を後記する水槽８ａの水Ｗ内に漬けてサイフォン管Ａ１内に水Ｗを充填し、ほぼ鉛直に立てたままサイフォン管Ａ１を水槽８ａ内から取り出す。この際、前記栓３１を抜いて空気抜き孔３０から縦・横管部３，４内の空気を抜くようにすれば、サイフォン管Ａ１を水槽８ａの水Ｗ内で上下逆にしなくても良く抜き易い。この状態では、図２に示すように両液溜め部６，６内の水Ｗは、空気に触れる面がそれぞれ同一高さとなり、しかも、その水面には同じ圧力が加わることから、サイフォン管Ａ１内の水Ｗは自然に抜け出ることなくそのまま留まっている。
【００１６】
そして、この状態を維持したまま、図３に示すように各縦管部４をそれぞれ隣り合う水槽８ａ，８ｂに入れ、各液溜め部６を各水槽８ａ，８ｂ内の等しい高さ位置にある台９の上面に設置する。そこで、例えば一方の水槽８ａの水Ｗを他方の水槽８ｂへ供給する場合、一方の水槽８ａ内に水Ｗを補給し貯水量を増やす。そして、図３実線に示される水位ｈ１が上昇して同図鎖線に示されるようにその水位ｈ２が液溜め部６の上面開口５を超えると、サイフォンの働きによりサイフォン管Ａ１内を水Ｗが流れ、一方の水槽８ａから他方の水槽８ｂへの水Ｗの供給が始まる。この場合、仮に、一方の水槽８ａ内の貯水量が減って、その水位が前記液溜め部６の上面開口５より下がると、水槽８ｂへの水Ｗの供給は停止される。
【００１７】
また、一方の水槽８ａ内の貯水量が増え、図３鎖線で示したようにその水位ｈ２が同側の液溜め部６の上面開口５を超えると、再びサイフォンの働きにより一方の水槽８ａから他方の水槽８ｂへの水の供給が始まる。このように、サイフォン管Ａ１内に水Ｗが留まったままでその一端部である液溜め部６が水槽８ａの水Ｗ中に漬かれば、そのときから自然とサイフォンが働いて他の水槽８ｂへの水Ｗの供給ができることになり、簡単で手間が掛からない。また、サイフォン管Ａ１の一端部、すなわち同側の液溜め部６の水槽８ａ内での高さ位置を変えることによってサイフォンが働きだす水位の位置が決められることから、その水位の変更が自由にできる。
【００１８】
図４は大小二個の前記サイフォン管Ａ１，Ａ１を鑑賞魚用の水槽に使用した使用状態図である。水Ｗが所定量充填される二つの水槽３２ａ，３２ｂが隣り合うようにして配置されている。一方の水槽３２ａ内にはその中に複数の魚Ｆが入れてある。そして、この水槽３２ａの上方に上面が開放する横長の中容器３３と小容器３４が配置されている。これら中容器３３と小容器３４内にも所定量の水Ｗが充填され、中容器３３が濾過用であって、小容器３４が水耕栽培用として用いられる。中容器３３内は仕切り板３３ａにより区画され、一方の収容部に綿、活性炭を複層に重ねた濾過材３５が敷き詰められ、他方の収容部には上下端面が開放すると共に中容器３３の底壁を貫通するようにして水抜き管３６ａが立設されている。この水抜き管３６ａの上端面は前記仕切り板３３ａの上端縁よりもやや低い位置に設定されている。また、前記仕切り板３３ａの下部には両収容部を連通させる通口３７が開設されている。
【００１９】
小容器３４内には、素焼きの小さいボール３９ａが沢山充填され、一側に上下端面が開放すると共に小容器３４の底壁を貫通するようにして水抜き管３６ｂが立設されている。この水抜き管３６ｂの上部には細かい編目の網を巻いて筒状に成形した網筒３８が嵌着され、水抜き管３６ｂの中に前記素焼きのボール３９ａが入らないようにしている。また、前記水抜き管３６ｂの上端面は小容器３４内の比較的低い位置に設定されている。この小容器３４内には水耕用の植物Ｐが植えられている。
【００２０】
他方の水槽３２ｂ内には、濾過材として細かい砂利３９が底面全体に敷き詰められ、ところどころに水草４０が植えられると共に小魚ｆが入れられている。また、水槽３２ｂ内に通水管４１が立設される。この通水管４１は、垂直な柱管４２の上部に上面が開口した太径部４３を有し、下部に前記水槽３２ｂの底面に敷かれる噴出し管４４を有している。この噴出し管４４には上側の長手方向に沿って水Ｗを噴出すための噴出口４５が複数個開設されている。そして、前記大型のサイフォン管Ａ１の一方の縦管部４の下部が中容器３３内に入れられると共に他方の縦管部４の下部が太径部４３内に入れられている。また、小型のサイフォン管Ａ１の一方の縦管部４の下部が小容器３４内に入れられると共に他方の縦管部４の下部が他方の水槽３２ｂ内に入れられている。大小両サイフォン管Ａ１，Ａ１は共に管本体１及び液溜め部６内に水Ｗが充填される。前記一方の水槽３２ａ内にはポンプ４６が設けられた揚水管４７が配設され、その吐出口が中容器３３の上面に臨むようになっている。
【００２１】
ここで、一方の水槽３２ａに貯留される水Ｗの水位ｈ３と、他方の水槽３２ｂに貯留される水Ｗの水位ｈ４と、中容器３３に貯留される水Ｗの水位ｈ５と、小容器３４に貯留される水Ｗの水位ｈ６との位置関係を示す。一番高い位置が中容器３３の水位ｈ５、二番目が他方の水槽３２ｂの水位ｈ４、三番目が小容器３４の水位ｈ６、一番低い位置が一方の水槽３２ａの水位ｈ３となっている。また、太径部４３内に貯留される水Ｗの水位ｈ７は、中容器３３の水位ｈ５よりも低く他の水槽３２ｂの水位ｈ４よりも高く設定される。更に、前記各サイフォン管Ａ１の各液溜め部６はいずれも水中に漬けられる。
【００２２】
このように構成される水槽３２ａ，３２ｂでは、ポンプ４６が作動すると一方の水槽３２ａ内の水Ｗが引き上げられ揚水管４７の吐出口から中容器３３に供給される。濾過材３５によって濾過された水は通口３７を通り他方の収容部内に入り、水抜き管３６ａ内にその上端面から流入するか、大型サイフォン管Ａ１の液溜め部６内に入る。前記水抜き管３６ａ内に入った水Ｗはそのまま一方の水槽３２ａ内に戻される。一方大型サイフォン管Ａ１の液溜め部６内に入った水Ｗは、大型のサイフォン管Ａ１を介して通水管４１の太径部４３内に入り更に柱管４２を降下すると共に噴出し管４４の各噴出口４５から上方へ噴出される。この際、多くの砂利を通過させることにより濾過作用がなされる。
【００２３】
他方の水槽３２ｂ内の水Ｗであってその中に漬かる小型のサイフォン管Ａ１内の水Ｗは、同サイフォン管Ａ１を介して小容器３４内に供給され植物Ｐが潤される。この小容器３４内の水Ｗは水抜き管３６ｂ内にその上端面から流入し、一方の水槽３２ａ内に戻される。前記小容器３４内の素焼きのボール３９ａによっても濾過作用がなされる。このような水槽３２ａ，３２ｂにしても第一実施の形態に係るサイフォン管Ａ１が利用でき、ポンプ４６により揚送された水Ｗは絶えず循環し、しかも、三重に濾過されるため水質保持に役立つ。
【００２４】
図５は第二実施の形態に係るサイフォン管の正面断面図である。このサイフォン管Ａ２は、第一実施の形態に係るサイフォン管Ａ１の管本体１と同じ材質・形状のものが使用され、管本体１の両先端面２，２が開放する両先端部１ａ，１ａを該各先端面２，２が上方を向くようにして曲げ、図５では略Ｕ字状に曲げ、ている。また、前記管本体１の両先端面２，２より上方は、中央の横管部３とその両端部に接続される縦管部４，４とにより正面門型に曲げられる。そして、前記各先端部１ａ，１ａの両先端面２，２は同じ高さ位置にあり、しかも、前記先端面２，２は互いに他方側の先端部１ａの最下部１０より上方に位置するように設定されている。このような構造であっても、前記管本体１内に水Ｗを充填して起立させたとき、前記管本体１内の水Ｗが自然と抜け出ることはなく、本発明と同等の作用・効果が得られる。
【００２５】
以下、第三乃至第五実施の形態に係るサイフォン管について説明するが、いずれも第一実施の形態に係るサイフォン管Ａ１または第二実施の形態に係るサイフォン管Ａ２とその構成が似ているので、同一部位は同一番号を付して詳しい説明は省略する。図６は第三実施の形態に係るサイフォン管の縦断正面図である。このサイフォン管Ａ３も第一実施の形態に係るサイフォン管Ａ１の管本体１と同じ材質・形状のものが使用される。このサイフォン管Ａ３は、管本体１の一方の先端部１ａに第一実施の形態に係るサイフォン管Ａ１と同じように液溜め部６を設け、他方の先端部１ａは、第二実施の形態に係るサイフォン管Ａ２と同じように略Ｕ字状に成形されている。この場合も、管本体１が両先端面２，２より上方で、中央の横管部３とその両端部に接続される縦管部４，４とにより正面門型に曲げられる。そして、前記管本体１における他方の先端部１ａは、その先端面２が上方を向くようにして曲げられる。しかも、前記管本体１における液溜め部６内の一方の先端部１ａの先端面２は前記他方の曲げられた先端部１ａの先端面２よりも下方に位置し、かつ、前記管本体１の他方の曲げられた先端部１ａにおける最下部１０は前記液溜め部６の上面開口５より下方に位置するように設定されている。このような構造であっても、前記管本体１内に水Ｗを充填して起立させたとき、前記管本体１内の水Ｗが自然と抜け出ることはなく、本発明と同等の作用・効果が得られる。
【００２６】
図７は第四実施の形態に係るサイフォン管の斜視図、図８は同正面断面図である。この第四実施の形態に係るサイフォン管Ａ４は、第一実施の形態に係る前記サイフォン管Ａ１よりもかなり大きく、また例えば、合成樹脂材により成形されるが、他に金属製、ガラス製またはセラミックス製であっても良い。このサイフォン管Ａ４は、両先端面２，２が開放すると共に両先端部１ａ，１ａを該各先端面２，２が上方を向くようにして略Ｕ字状に曲げ、また、前記両先端面２，２より上方が、中央の横管部３とその両端部に接続される縦管部４，４とにより正面門型に曲げられる管本体１と、前記管本体１の最上部に設けられ水を注入するための供給口１１と、前記両先端部１ａ，１ａの先端面２，２及び前記供給口１１にそれぞれ開閉可能に取着される開閉部材と、からなる。前記横管部３がほぼ１５００ｍｍ、各縦管部４がほぼ１０００ｍｍの寸法を有し、サイフォン管Ａ４の内径はほぼ１００ｍｍの寸法を有する。
【００２７】
更に、詳しく説明すると、前記各先端部１ａは、縦管部３ａの下端部に外側へほぼ直角に屈曲して接続される横短管部１３とその先端部に上方へほぼ直角に屈曲して接続される縦短管部１４が接続され、この縦短管部１４の上端面が先端面２となる。また、前記横管部３を水平に保持したとき、前記各縦短管部１４の先端部１ａとその各先端面２もそれぞれ同一高さに位置にある。
【００２８】
前記管本体１の最上部である横管部３の一側に、一方の縦管部４の上方でありかつ横管部３を超えて横管部３および縦管部４と連通する短管部１５が設けられている。この短管部１５の上端に前記供給口１１が設けられる。前記各縦短管部１４の上端外周面と短管部１５の上端外周面とにはいずれも螺子部１６が刻設され、開閉部材である螺子付き蓋１７を前記螺子部１６に嵌着して螺締めすることにより、前記各縦短管部１４の先端面２と短管部１５の供給口１１に螺子付き蓋１７が開閉可能に取着される。また、前記管本体１の最下部である各横短管部１３の一側に、サイフォン管Ａ４内に充填された水をすべて排出するための水抜き管１８が接続される。この水抜き管１８の先端部外周面にも螺子部１６が刻設され、開閉部材である螺子付き蓋１７を前記螺子部１６に嵌着して螺締めすることにより、前記各水抜き管１８先端の排出口１９に螺子付き蓋１７が開閉可能に取着される。なお、前記各螺子付き蓋１７を締めた状態では、サイフォン管Ａ４内が密閉され無用に空気が入らないようになっている。
【００２９】
この場合も、両先端部１ａ，１ａ及びその先端面２，２も同じ高さ位置にあり、しかも、前記両先端部１ａ，１ａの各先端面２，２は、互いに他方側の先端部１ａの最下部１０より上方に位置するように設定されている。これにより、前記管本体１内に水Ｗを充填すると共に両縦短管部１４，１４の先端面２，２を開けた状態で起立させたとき、常態では、前記管本体１内の水Ｗが自然と抜け出ることはない。
【００３０】
第四実施の形態に係るサイフォン管Ａ４は上記構成からなる。そして、設置する前にサイフォン管Ａ４を起立させ各先端面２と各排出口１９との螺子付き蓋１７をしっかり締めた状態で、短管部１５上端の供給口１１の螺子付き蓋１７を外し、供給口１１からサイフォン管Ａ４内に水Ｗを満タンになるまで充填する。そして、前記供給口１１を螺子付き蓋１７により密閉した後に、図９に示すように隣接する水槽２０ａ，２０ｂ内の等しい高さ位置にある台２１の上面にそれぞれ各先端部１ａ，１ａを配置する。この状態で、前記両先端面２，２の螺子付き蓋１７を取り外して先端面２，２を開ける。これにより、第一実施の形態と同様にサイフォンが働いて水の供給が行なえるようになる。
【００３１】
すなわち、一方の水槽２０ａの水Ｗを他方の水槽２０ｂへ供給する場合、一方の水槽２０ａ内に水Ｗを補給し貯水量を増やす。そして、図９実線に示される水位ｈ１が上昇して同図鎖線に示されるようにその水位ｈ２が先端部１ａの先端面２を超えると、サイフォンの働きによりサイフォン管Ａ４内を水Ｗが流れ、一方の水槽２０ａから他方の水槽２０ｂへ水Ｗの供給が始まる。この場合、仮に、一方の水槽２０ａ内の貯水量が減って、その水位が前記先端部１ａの先端面２より下がると、水槽２０ｂへの水Ｗの供給は停止される。
【００３２】
このように、サイフォン管Ａ４内に水Ｗが留まったままで、その一端部である先端部１ａが水槽２０ａの水Ｗ中に漬かれば、そのときから自然とサイフォンが働いて他の水槽２０ｂへの水Ｗの供給ができることになり、簡単で時間が掛からない。特に、サイフォン管Ａ４が大型化すると、自由に持ち上げたり移動できないことから至便である。また、サイフォン管Ａ４の一端部、すなわち同側の先端部１ａの水槽２０ａ内での高さ位置を変えることによってサイフォンが働きだす水位が決められることから、その水位の変更が自由にできる。なお、前記開閉部材としては、螺子付き蓋１７以外にバルブでも良い。また、前記水を取り入れる側の先端部１ａであって、縦短管部１４の先端面２には開閉部材として逆止弁を使用するようにしても良い。第四実施の形態では、サイフォン管Ａ４が大型化して簡単に移動できないことから、各所に供給口１１、排出口１９が必要になるが、これによりサイフォン管Ａ４をほとんど移動させることなく水Ｗの充填または排出が簡単にできることになり、サイフォンもスムーズに働くことになる。
【００３３】
図１０は第五実施の形態に係るサイフォン管の使用状態図である。このサイフォン管Ａ５は、第四実施の形態に係るサイフォン管Ａ４よりも更に大きく成形されるが、ほとんど第四実施の形態に係るサイフォン管Ａ４と同じ構成からなる。この場合、図１０に示すように擁壁２２を挟んで一方が大雨のとき雨水が頻繁にたまり水はけの悪いエリア２３ａ、また、他方が水はけの良いエリア２３ｂとする。そして、サイフォン管Ａ５は前記擁壁２２を跨ぐようにし、また、両先端部１ａ，１ａを地面Ｅに設置された同じ高さの台枠２４上面に載置し起立した状態で据置固定する。このサイフォン管Ａ５は一年の内、梅雨時など降雨量の多い時期のみ使用され、降雨の少ない時期はほとんど使用されることなない。
【００３４】
このため、使用しない時は、各開閉部材である螺子付き蓋１７を各先端面２等に被せて閉塞し、管本体１内にゴミ等が入らないようにしておく。一方、雨期になって降雨が多くなりそうなときは、各先端面２と各排出口１９との螺子付き蓋１７をしっかり締めた状態で、前記供給口１１の螺子付き蓋１７を外し、その供給口１１からサイフォン管Ａ５内に水Ｗを満タンになるまで充填する。そして、前記供給口１１を螺子付き蓋１７により密閉する。この状態で、前記各先端面２の螺子付き蓋１７を取り外し、両先端面２，２を開けておく。この状態は数ヶ月続くことから、前記各先端面２から管本体１内にできるだけゴミが入らないように各先端面２の上方にその開口を覆う傘部材２５が設けられている。
【００３５】
そこで、一度に多くの雨が降り、水はけの悪いエリア２３ａに水がたまり、図１０鎖線に示すようにその水位ｈ３が上昇して同じ側の縦短管部１４の先端面２を超えると、サイフォンが働き自然と水はけの良いエリア２３ｂ側への雨水の排水が行なわれることになる。よって、必要個所に逐一サイフォン管Ａ５を設置しておけば、例えば家屋の冠水等が防止できることになる。同様に、池、プール等の水を汲み出す場合にも利用できること勿論である。
【００３６】
本発明は、液体として水、雨水について説明したが、他に例えば海水、油、ジュース等の飲料、薬液といったものについても使用でき、これら関連産業に広く利用でき汎用性が高い。
【００３７】
【発明の効果】
以上説明したように、本発明に係るサイフォン管は、液体の中に漬けておかなくても、管本体内に液体を留まらせておくことができることから、サイフォン管内に液体が留まったままでその一端部である先端面を一方の液体中に漬ければ、そのときから自然とサイフォンが働いて他への液体の供給ができることになり、簡単で手間が掛からない。また、途中で液槽の液体内から自在に出し入れしても常にサイフォンが働き、使い勝手が良いという有益な効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a siphon tube used when, for example, water is supplied from one water tank to the other water tank.
[0002]
[Prior art]
Conventionally, siphon tubes that do not require the use of electric appliances such as pumps are used to supply water from a high water tank to a low water tank where aquariums such as goldfish and tropical fish are kept ( For example, see Patent Document 1.)
[0003]
[Patent Document 1]
Japanese Utility Model Publication No. 6-60345 (page 1-2, FIG. 1)
[0004]
[Problems to be solved by the invention]
Since the siphon tube of Patent Document 1 has an inverted U shape and is disposed so as to straddle one side wall of the water tank and is provided with both open end faces downward, for example, the water tank on the supply side When the amount of water decreases and the water level falls below the tip surface of the siphon tube, the water in the siphon tube also naturally escapes and the supply of water stops. Therefore, in order to work the siphon tube once it has run out of water, it takes time and effort to increase the amount of water in the water tank on the supply side, soak the entire siphon tube in water, and remove the air in the siphon tube. . For this reason, when the siphon is operated and the water in one tank is started to be supplied to the other tank, it takes time to operate the siphon tube again as described above. There is a problem that it is difficult to stop and is not easy to use.

The case where it is used in various places is shown respectively.
[0013]
FIG. 1 is a perspective view of a siphon tube according to the first embodiment, and FIG. 2 is a longitudinal front view of the same. The siphon tube A1 is formed of, for example, a synthetic resin material, but may be made of metal, glass, or ceramics. The siphon tube A1 is formed from a cylinder whose both end surfaces 2 are open, and is a tube body formed into a front gate shape by a central horizontal tube portion 3 and vertical tube portions 4, 4 connected to both ends thereof. 1 and liquid reservoirs 6, 6 provided at the lower ends of the vertical pipe parts 4, 4, which are the front end parts 1 a of the pipe main body 1, so as to communicate with the vertical pipe parts 4 and whose upper surfaces are open 5. And consist of The horizontal tube portion 3 has a size of approximately 230 mm, each vertical tube portion 4 has a size of approximately 200 mm, and the inner diameter of the tube body 1 has a size of approximately 15 mm. Moreover, when the said horizontal pipe part 3 is hold | maintained horizontally, it becomes the both front end surfaces 2 of the pipe main body 1. Both vertical pipes 4, 4 Are located at the same height, and the upper surface openings 5 and 5 of the liquid reservoirs 6 and 6 are also at the same height. An air vent hole 30 is formed on one side upper surface of the horizontal tube portion 3, and a rubber plug 31 is removably fitted into the air vent hole 30.
[0014]
Each of the liquid reservoirs 6 is formed of a bottomed cylindrical body, and is firmly fixed by ribs 7 projecting radially on the outer peripheral surface of the vertical tube portion 4, and the front end surface 2 of each vertical tube portion 4 is a liquid reservoir portion. 6 will intervene. Moreover, the distal end surfaces 2 and 2 of the tube body 1 are set so as to be positioned below the upper surface opening 5 of the liquid reservoirs 6 and 6 on the other side. Thereby, when the water W which is a liquid is filled and it stands in the said pipe | tube main body 1 and the said both liquid reservoir parts 6 and 6, the front end surface 2 of each said vertical pipe part 4 becomes each liquid reservoir part 6. In the normal state, the water W in the pipe body 1 does not escape naturally.
[0015]
Siphon pipe | tube A1 which concerns on 1st embodiment consists of the said structure. Although illustration is omitted, before use, the entire siphon tube A1 is immersed in water W of a water tank 8a which will be described later, and the water W is filled in the siphon tube A1, and the siphon tube A1 is placed in the water tank 8a while standing almost vertically. Take out from. At this time, if the plug 31 is pulled out so that the air in the vertical and horizontal tube portions 3 and 4 is extracted from the air vent hole 30, the siphon tube A1 does not need to be turned upside down in the water W of the water tank 8a. easy. In this state, as shown in FIG. 2, the surfaces of the water W in the liquid reservoirs 6 and 6 that are in contact with air have the same height, and the same pressure is applied to the water surface, so the siphon tube A1. The water W inside remains as it is without getting out naturally.

It is installed on the upper surface of the base 9. Therefore, for example, when the water W of one water tank 8a is supplied to the other water tank 8b, the water W is supplied into the one water tank 8a to increase the amount of stored water. Then, when the water level h1 shown by the solid line in FIG. 3 rises and the water level h2 exceeds the upper surface opening 5 of the liquid reservoir 6 as shown by the chain line in FIG. 3, the water W flows inside the siphon tube A1 by the action of the siphon. The water W starts to flow from one water tank 8a to the other water tank 8b. In this case, if the amount of water stored in one of the water tanks 8a decreases and the water level falls below the upper surface opening 5 of the liquid reservoir 6, the supply of water W to the water tank 8b is stopped.
[0017]
Further, if the amount of water stored in one of the water tanks 8a increases and the water level h2 exceeds the upper surface opening 5 of the liquid reservoir 6 on the same side as shown by the chain line in FIG. The supply of water to the other water tank 8b starts. Thus, if the water reservoir 6 which is the one end part is immersed in the water W of the water tank 8a while the water W remains in the siphon tube A1, the siphon will work naturally from that time to the other water tank 8b. Water W can be supplied, and it is easy and does not take time. Moreover, since the position of the water level at which the siphon works is determined by changing the height position in the water tank 8a of the one end of the siphon tube A1, that is, the liquid reservoir 6 on the same side, the water level can be freely changed. it can.

Is obtained.
[0026]
FIG. 7 is a perspective view of a siphon tube according to the fourth embodiment, and FIG. 8 is a front sectional view thereof. The siphon tube A4 according to the fourth embodiment is considerably larger than the siphon tube A1 according to the first embodiment, and is formed of, for example, a synthetic resin material. It may be made. The siphon tube A4 is formed by bending both tip portions 1a and 1a into a substantially U shape so that the tip surfaces 1 and 2a face upward, and the tip surfaces 2 and 2 are open. 2 and 2 are provided at the top of the tube body 1 and the tube body 1 bent into a front gate shape by the central horizontal tube portion 3 and the vertical tube portions 4 and 4 connected to both ends thereof. It consists of a supply port 11 for injecting water, and open / close members attached to the front end surfaces 2 and 2 of the two end portions 1a and 1a and the supply port 11 so as to be openable and closable. The horizontal tube portion 3 has a size of about 1500 mm, each vertical tube portion 4 has a size of about 1000 mm, and the inner diameter of the siphon tube A4 has a size of about 100 mm.
[0027]
More specifically, each of the distal end portions 1a has a lateral short tube portion 13 connected to the lower end portion of the vertical tube portion 3a by being bent outward at a substantially right angle, and bent upward at a substantially right angle to the distal end portion thereof. The vertical short pipe portion 14 to be connected is connected, and the upper end surface of the vertical short pipe portion 14 is the tip surface 2. Further, when the horizontal tube portion 3 is held horizontally, the distal end portion 1a of each vertical short tube portion 14 and each distal end surface 2 thereof are at the same height.
[0028]
Above Tube body 1 A short pipe portion 15 is provided on one side of the horizontal pipe portion 3 that is the top of the horizontal pipe portion 4 and is above the one vertical pipe portion 4 and communicates with the horizontal pipe portion 3 and the vertical pipe portion 4 beyond the horizontal pipe portion 3. It has been. The supply port 11 is provided at the upper end of the short pipe portion 15. A screw portion 16 is engraved on both the upper end outer peripheral surface of each vertical short tube portion 14 and the upper end outer peripheral surface of the short tube portion 15, and a screwed lid 17 as an opening / closing member is fitted to the screw portion 16. Then, the screw-attached lid 17 is attached to the distal end surface 2 of each of the vertical short tube portions 14 and the supply port 11 of the short tube portion 15 so as to be openable and closable. Further, a drain pipe 18 for discharging all the water filled in the siphon pipe A4 is connected to one side of each horizontal short pipe portion 13 which is the lowermost part of the pipe body 1. A threaded portion 16 is also engraved on the outer peripheral surface of the distal end portion of the drainage pipe 18, and a screwed lid 17 that is an opening / closing member is fitted into the threaded portion 16 and screwed to tighten each drainage pipe 18. A screw-attached lid 17 is attached to the discharge port 19 at the tip so as to be openable and closable. In the state where each of the screw-attached lids 17 is tightened, the inside of the siphon tube A4 is sealed so that air does not enter unnecessarily.
[0029]
Also in this case, both the tip portions 1a and 1a and the tip surfaces 2 and 2 thereof are at the same height position, and the tip surfaces 2 and 2 of the tip portions 1a and 1a are the tip portions 1a on the other side. It is set so as to be located above the lowermost part 10. As a result, when the pipe body 1 is filled with water W and is erected in a state where the front end faces 2 and 2 of both the vertical short pipe portions 14 and 14 are opened, the water W in the pipe body 1 is normally set. Will not escape naturally.
[0030]
The siphon tube A4 according to the fourth embodiment has the above configuration. Then, before installation, the siphon tube A4 is erected and the screw cap 17 of the upper end of the short tube portion 15 is removed while the screw cap 17 of each distal end surface 2 and each discharge port 19 is firmly tightened. Then, the water W is filled into the siphon tube A4 from the supply port 11 until it is full. Then, after the supply port 11 is sealed with the screwed lid 17, the tip portions 1a and 1a are arranged on the upper surface of the base 21 at the same height in the adjacent water tanks 20a and 20b as shown in FIG. To do. In this state, the screw-attached lids 17 on both the front end surfaces 2 and 2 are removed and the front end surfaces 2 and 2 are opened. As a result, as in the first embodiment, the siphon works and water can be supplied.
[0031]
That is, when supplying the water W of one water tank 20a to the other water tank 20b, the water W is replenished in one water tank 20a and the amount of stored water is increased. Then, when the water level h1 shown by the solid line in FIG. 9 rises and the water level h2 exceeds the tip surface 2 of the tip 1a as shown by the chain line in FIG. 9, the water W flows in the siphon tube A4 by the action of the siphon. The supply of water W from one water tank 20a to the other water tank 20b starts. In this case, if the amount of water stored in one of the water tanks 20a decreases and the water level falls below the front end surface 2 of the front end part 1a, the supply of water W to the water tank 20b is stopped.
[0032]
Thus, if the water W remains in the siphon tube A4 and the tip portion 1a, which is one end thereof, is immersed in the water W of the water tank 20a, the siphon naturally works from that time to the other water tank 20b. Water W can be supplied, which is simple and does not take much time. In particular, when the siphon tube A4 is enlarged, it is convenient because it cannot be lifted or moved freely. Further, since the water level at which the siphon is activated is determined by changing the height position of the one end portion of the siphon tube A4, that is, the tip portion 1a on the same side, in the water tank 20a, the water level can be freely changed. The opening / closing member may be a valve other than the screwed lid 17. Further, a check valve may be used as an opening / closing member at the distal end portion 1a on the side of taking in the water and on the distal end surface 2 of the vertical short tube portion. In the fourth embodiment, since the siphon tube A4 is enlarged and cannot be easily moved, the supply port 11 and the discharge port 19 are necessary in various places. However, the water W can be moved without almost moving the siphon tube A4. It will be easy to fill or drain, and the siphon will work smoothly.
[0033]
FIG. 10 is a use state diagram of the siphon tube according to the fifth embodiment. The siphon tube A5 is formed to be larger than the siphon tube A4 according to the fourth embodiment, but has almost the same configuration as the siphon tube A4 according to the fourth embodiment. In this case, as shown in FIG. 10, when one side is heavy rain with the retaining wall 22 sandwiched, rainwater is frequently accumulated and the area 23a is poorly drained, and the other is the area 23b that is well drained. The siphon tube A5 straddles the retaining wall 22, and both end portions 1a and 1a are placed on the upper surface of the frame 24 of the same height installed on the ground E and fixed in a standing state. This siphon tube A5 is used only during the year when there is a large amount of rainfall, such as during the rainy season, and is rarely used during a time when there is little rainfall.
[0034]
For this reason, when not in use, the lid 17 with a screw, which is each opening and closing member, is covered with each tip end surface 2 and the like so as to prevent dust and the like from entering the tube main body 1. On the other hand, when rain is likely to increase during the rainy season, the screwed lid 17 of the supply port 11 is removed with the screwed lids 17 of the front end surfaces 2 and the discharge ports 19 firmly tightened. The water W is filled into the siphon tube A5 from the supply port 11 until it is full. Then, the supply port 11 is sealed with a screwed lid 17. In this state, the screwed lids 17 of the respective front end surfaces 2 are removed, and both the front end surfaces 2 and 2 are opened. Since this state lasts for several months, an umbrella member 25 is provided above each tip surface 2 so as to prevent dust from entering the pipe body 1 from each tip surface 2 as much as possible.
[0035]
Therefore, when a lot of rain falls at one time, water accumulates in the poorly drained area 23a, and the water level h3 rises as shown by the chain line in FIG. 10 and exceeds the distal end surface 2 of the vertical short tube portion 14 on the same side. The siphon works and drains rainwater to the area 23b where nature and drainage are good. Therefore, if the siphon tube A5 is installed one by one at a necessary place, for example, flooding of a house can be prevented. Similarly, it can of course be used when pumping out water from a pond, a pool or the like.
[0036]
Although the present invention has been described with respect to water and rainwater as liquids, it can also be used for drinks such as seawater, oil, juice, and chemicals, and can be widely used in these related industries and has high versatility.
[0037]
【The invention's effect】
As described above, the siphon tube according to the present invention can retain the liquid in the tube body without being immersed in the liquid. If the tip surface, which is a part, is soaked in one liquid, the siphon will work naturally from that time, and the liquid can be supplied to the other, which is simple and labor-saving. In addition, even if it is freely taken in and out of the liquid in the liquid tank on the way, the siphon always works and there is a beneficial effect that it is easy to use.
