Description

【０００１】
【産業上の利用分野】
本発明は、主として金魚、熱帯魚等の観賞魚や水草を育成する水槽の内面を清掃するための、清掃具に関するものである。
【０００２】
【従来の技術】
一般に水槽内で観賞魚等を飼育、育成する場合に、水槽内の水に藻や苔類が発生し、それが次第に水槽の透明な内壁面に付着、堆積して観賞魚等を見ずらくすることがあり、このような場合に従来では人が水槽内に手を入れて清掃具で、付着した藻や苔類を擦り取るようにしていた。
【０００３】
【発明が解決しようとする課題】
ところで前述したように水槽内で単に藻や苔類を擦り取るようにすると、その擦り取られた藻や苔類は水槽内の水中に拡散するだけで、水を汚損するばかりでなく、暫くすると再び拡散した藻や苔類は水槽の内面に付着、堆積してしまうという問題がある。
【０００４】
本発明は斯かる実情に鑑みてなされたもので、水槽内面に付着、堆積した藻や苔類を能率よく取り除くことができ、しかもその取り除いた藻や苔類を水中に拡散させずに水槽の外に取り出すことができるようにした、新規な水槽の清掃具を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
前記目的達成のため、請求項１記載の発明は、水槽の内面を清掃するための清掃具であって、内部に吸込室を画成する中空の清掃具本体の一面に、該吸込室に連なる開口部を設け、この開口部を覆う掻取片を前記清掃具本体に、その一面に略沿って第１の作動位置と第２の作動位置との間を摺動し得るように支持し、その掻取片の、前記摺動方向の両端縁部には、水槽内面の藻、苔等の付着物を掻き取るよう水槽内面に摺接可能な一対の掻取部をそれぞれ一体的に沿設し、前記掻取片は、それの前記第１の作動位置では前記開口部の一側縁部に一方の掻取部が密接し且つその他側縁部と他方の掻取部との間にスリット状の第１間隙が生じるように、また前記第２の作動位置では前記他側縁部に前記他方の掻取部が密接し且つ前記一側縁部と前記一方の掻取部との間にスリット状の第２間隙が生じるように、形成され、更に前記清掃具本体の他面には、吸込パイプが接続される吸出口を開口したことを特徴とする。
【０００６】
更に請求項２記載の発明は、前記請求項１の特徴に加えて、前記吸出口が、前記清掃具本体の他面に回動可能に支持された吸出筒より構成されたことを特徴とする。
【０００７】
【作用】
請求項１の発明の構成によれば、清掃に当たっては、吸込パイプに吸水ホース等の吸水手段を接続した状態で、清掃具本体又は吸込パイプの清掃具本体近傍部を掴んで該清掃具本体の一面（従って吸込口）を水槽内面に対面させながら掻取片を水槽内面に摺接させるようにする。これにより、水槽の内面に付着、堆積する藻、苔類が能率よく掻き取られると共に、吸込口より吸込室、延いては吸水手段側へ吸い出されるため、その掻き取った苔、藻類を水中に拡散させることなく水槽外に効率よく除去できる。
【０００８】
即ち、清掃に当たっては、清掃具本体の一面（従って掻取片）を水槽内面に対面させながら該掻取片両端の掻取部を水槽内面に摺接させるが、特にその摺接方向を、掻取片の清掃具本体に対する摺動方向に沿う一方向と他方向に交互に切換えるようにすると、その切換の都度、摺接抵抗により掻取片が摺接方向後側に自動的にずれ動いて（即ち前記第１及び第２作動位置間を交互に移動して）その摺接方向前側の掻取部の前方にだけ吸込口となる間隙を生じさせることができる。これにより、清掃具本体を上記一方向と他方向の何れの方向に移動させる場合にもその移動方向前寄りに位置する掻取部とこれに対応する間隙との協働により、水槽内面の藻、苔類を極めて能率よく掻き取って吸込室、延いては吸水手段側へ吸い出すことができる。
【０００９】
更に請求項２の発明の構成によれば、清掃のために清掃具本体を移動させることに伴い該本体と吸水ホース等の吸水手段との相対位置が変化しても、その変化が吸出筒の回動により無理なく許容され、従って該ホース等が前記相対位置変化のために無理に折れ曲げられたり捩られたりする虞れはない。
【００１０】
【実施例】
以下、図面を参照して本発明の好適な実施例について説明する。図１〜６は本発明清掃具の一実施例を示すもので、図１はその全体正面図、図２は、清掃具単体の斜視図、図３は、清掃具を下降させながらの清掃状態を示す、清掃具の横断面図、図４は、清掃具を上昇させながらの清掃状態を示す、清掃具の横断面図、図５は、図４の５矢視より見た一部破断図、図６は、図５の６矢視より見た一部破断図である。
【００１１】
清掃具の主体部を構成する清掃具本体Ｃは、無色透明の硬質合成樹脂材により一面、即ち底面ｆを開放した略屋根状の中空体に形成されており、その中空部が本発明の吸込室１となっている。この清掃具本体Ｃの開放底面ｆは略長方形に形成されており、その開口部Ｏには、無色透明の硬質合成樹脂材により略長方形状に形成された扁平板よりなる掻取片Ｐが嵌合されて該開口部Ｏを覆っている。而して前記開放底面ｆの開口部Ｏが、清掃具本体Ｃの一面に形成される本発明の開口部を構成する。
【００１２】
その掻取片Ｐの短辺側の両側縁部２ｓ，２ｓは清掃具本体Ｃの対応する両端壁４ｓ，４ｓ内面にそれぞれ形成した溝状の案内凹部３に摺動自在に係合支持されており、その摺動により掻取片Ｐは、清掃具本体Ｃの底面ｆに沿って第１の作動位置（図３）と第２の作動位置（図４）との間を所定の小範囲に亘り自在に移動可能である。その掻取片Ｐの、摺動方向ｓの両端縁部、即ち長辺側の両側縁部には、清掃具本体Ｃの対応する傾斜側壁部４₁，４₂に略沿うように各々外方下向きに傾斜した一対のエッジ状掻取部５₁，５₂がそれぞれ一体に沿設されており、これら掻取部５₁，５₂の先端縁ｅ₁，ｅ₂は、清掃具本体Ｃの開放底面ｆよりも若干外方に張り出していて、水槽Ｔのガラス壁Ｗ内面の藻、苔等の付着物Ａを掻き取るよう同壁Ｗ内面に摺接可能である。
【００１３】
前記掻取片Ｐは、図３に示す第１の作動位置では一方の傾斜壁部４₂に一方の掻取部５₂が密接し且つ他方の傾斜壁部４₁と他方の掻取部５₁との間にスリット状の第１間隙Ｓ₁が生じるように、また図４に示す第２の作動位置では前記他方の傾斜壁部₁に他方の掻取部５₁が密接し且つ前記一方の傾斜壁部４₂と一方の掻取部５₂との間にスリット状の第２間隙Ｓ₂が生じるように、形状・大きさ等が設定される。而して前記スリット状の各間隙Ｓ₁，Ｓ₂は請求項１の発明において吸込口を構成し、更に前記一対の傾斜壁部４₁，４₂は、請求項２の発明において清掃具本体Ｃの開口部Ｏの一対の側縁部を構成している。
【００１４】
更に前記清掃具本体Ｃの頂面には吸出口が開口される。この吸出口は、図示例では清掃具本体Ｃの頂部に設けた支持孔１２に回動可能に嵌合支持されて前記吸込室１と直接連通する基部筒８ａと、この基部筒８ａの中央部に直交して該基部筒８ａ内と直接連通する先部筒８ｂとを一体化したＴ字状の吸出筒８より構成されており、その先部筒８ｂの自由端部外周には、硬質の吸込パイプ７の基端が直接又はジョイント（図示せず）を介して接続される。前記基部筒８ａの外周面には、該筒８ａの軸方向の動きを規制すべく前記支持孔１２に凹凸係合する係止突部８ｃが一体に突設されている。
【００１５】
前記吸込パイプ７の先端には可撓性を有するビニールチューブ等の吸水ホース９が接続され、その吸水ホース９の途中には、逆止弁内蔵の手押ポンプ１０が介装されている。而して該吸水ホース９及び手押ポンプ１０は互いに協働して、吸込室１内の水を吸込パイプ７を通して吸い込むための吸水手段を構成する。
【００１６】
尚、図３〜６において、４ｍは、清掃具本体Ｃの、一対の傾斜側壁部４₁，４₂間に跨がって延びる中間壁であって、前記支持孔１２の下部周壁と一体に形成されている。この中間壁４ｍの下面には、相互に間隔をおいて平行に延びる一対の補強リブ６，６が一体に垂設されており、このリブ６は、一対の傾斜側壁部４₁，４₂間を一体に結合してそれらを補強する機能と、該リブ６下端面に掻取片Ｐの上面を摺動可能に当接させて掻取片Ｐを支持する機能とを兼ね備えるものである。尚、図示はしないが、前記補強リブ６には、吸込室１内において該リブ６の内外の空間相互を連通させるための連通路、例えば貫通孔や切欠き状の溝部を適宜設けてもよい。
【００１７】
次に前記実施例の作用について説明すると、清掃に当たっては、吸出筒８に吸込パイプ７を介して吸水ホース９を接続した状態の清掃具本体Ｃを、該本体Ｃ自体又は吸込パイプ７等を手で掴んで図３〜６に示す如く水槽Ｔの水中内に浸漬させ、その本体底面ｆ側の掻取片Ｐを水槽Ｔのガラス壁Ｗ内面に軽く圧接させたまま、該掻取片Ｐの両掻取部５₁，５₂の先端縁ｅ₁，ｅ₂を前記ガラス壁Ｗ内面に摺接させるようにする。この場合、その摺接方向を、掻取片Ｐの清掃具本体Ｃに対する摺動方向ｓに沿う一方向（例えば図３に矢印Ｄで示す下方向）と他方向（例えば図４に矢印Ｕで示す上方向）に交互に切換えるべく清掃具本体Ｃを上下に往復動させると、その方向切換の都度、摺接抵抗により掻取片Ｐが摺接方向後側に自動的にずれ動いて前記第１及び第２作動位置間を交互に移動し、その際に摺接方向前側の掻取部５₁（５₂）の前方にだけ吸込口となる間隙Ｓ₁（Ｓ₂）を生じさせることができる。このため、清掃具本体Ｃを上記一方向と他方向の何れの方向に移動させる場合にも、その移動方向前寄りに位置する掻取部５₁（５₂）とこれに対応する間隙Ｓ₁（Ｓ₂）との協働によって、前記ガラス壁Ｗ内面の藻、苔類等を極めて能率よく掻き取ることができる。
【００１８】
従って斯かる掻き取り作業を吸水手段たる手押ポンプ１４の動作状態で行えば、前記掻き取られた藻、苔類等の付着物Ａが水槽Ｔ内の水と共に図３〜６に矢印で示すように前記間隙Ｓ₁（Ｓ₂）を経て吸込室１内に吸引され、更に吸込パイプ７および吸水ホース９を通って水槽Ｔ外の容器１１内に取り出される。この場合において、図示例のように清掃具本体Ｃ及び掻取片Ｐを透明体で構成すれば、前記付着物Ａが掻取部５₁（５₂）で掻き取られる様子や、前記間隙Ｓ₁（Ｓ₂）を経て吸込室１内を流れる様子等を具に観察、チェックすることができるから、前記清掃作業を的確に行い得ると共にその作業能率の一層の向上が図られる。
【００１９】
かくして掻取部５₁，５₂により掻き取られた藻、苔類等の付着物Ａは水槽Ｔの水中内に拡散する前に水槽Ｔ外に除去することができる。
【００２０】
以上、本発明の一実施例について説明したが、本発明はその実施例に限定されることなく、本発明の範囲内で種々の実施例が可能である。例えば前記実施例では、水槽内の水を清掃具内に吸込むための吸水手段として手押ポンプを使用しているが、これに代えてサイフォン作用により水を吸込むようにしてもよく、また電動式の吸込ポンプを利用してもよい。更に前記実施例では、清掃具本体の一面（底面）全面を開口したものを示したが、本発明では清掃具本体一面の一部だけを開口して開口部としてもよい。更にまた前記実施例では、吸出筒としてＴ字状のものを用いて清掃具本体の頂部に回動自在に支持したものを示したが、その支持位置は清掃具本体の端壁であってもよく、また該吸出筒を清掃具本体に固着又は一体化してもよい。更にまた吸込パイプとしては、硬質パイプの他、可撓性を有するビニールチューブを用いてもよく、その場合には、そのチューブに手押ポンプ等の吸水手段を直接に接続可能であり、また該チューブの清掃具本体に近い部分の剛性を高め（即ち腰を強くし）て水槽清掃時に手で掴み易くし取扱い性をよくするために、該部分においてチューブを二重管としてもよい。
【００２１】
【発明の効果】
以上のように本発明によれば、吸込パイプに吸水ホース等の吸水手段を接続した状態で、清掃具本体の一面（従って吸込口）を水槽内面に対面させながら掻取片を水槽内面に摺接させるようにすると、水槽の内面に付着、堆積する藻、苔類を能率よく掻き取ることができると共に、吸込口より吸込室、延いては吸水手段側へ吸い出すことができるので、その掻き取った苔、藻類を水中に拡散させることなく水槽外に効率よく除去することができ、従って水を汚さずに水槽内面の清掃を簡単且つ的確に行うことができる。
【００２２】
また特に清掃具本体の一面（従って掻取片）を水槽内面に対面させながら該掻取片両端の掻取部を水槽内面に摺接させるに当たり、その摺接方向を、掻取片の清掃具本体に対する摺動方向に沿う一方向と他方向に交互に切換えるようにすると、その切換の都度、摺接抵抗により掻取片が摺接方向後側に自動的にずれ動いて、その摺接方向前側の掻取部の前方にだけ吸込口となる間隙を生じさせることができるから、清掃具本体を上記一方向と他方向の何れの方向に移動させる場合にもその移動方向前寄りに位置する掻取部とこれに対応する間隙との協働により、水槽内面の藻、苔類を極めて能率よく掻き取って吸込室、延いては吸水手段側へ吸い出すことができ、前記清掃効果を能率よく達成し得る。
【００２３】
更に請求項２の発明によれば、吸出口が、清掃具本体の他面に回動可能に支持された吸出筒より構成されるので、清掃のために清掃具本体を移動させることに伴い該本体と吸水ホース等の吸水手段との相対位置が変化しても、その変化に応じて吸出筒を回動させることで、その変化に伴う該ホース等の折曲や捩りが効果的に回避される。

[Industrial applications]
The present invention relates to a cleaning tool for cleaning an inner surface of an aquarium for growing ornamental fish such as goldfish and tropical fish and aquatic plants.
[0002]
[Prior art]
Generally, when breeding and breeding ornamental fish in an aquarium, algae and moss are generated in the water in the aquarium, which gradually adhere to and accumulate on the transparent inner wall of the aquarium, making it difficult to see the aquarium fish. In such a case, conventionally, a person puts his hand in the water tank and scrapes off the attached algae and moss with a cleaning tool.
[0003]
[Problems to be solved by the invention]
By the way, as described above, if you simply scrape algae and moss in the water tank, the scraped algae and moss will only diffuse into the water in the tank and not only pollute the water, but after a while There is a problem that the algae and moss spread again adhere to and accumulate on the inner surface of the aquarium.
[0004]
The present invention has been made in view of such circumstances, and can efficiently remove algae and moss attached and deposited on the inner surface of the aquarium, and furthermore, the algae and moss removed without diffusing into the water. It is an object of the present invention to provide a novel water tank cleaning tool that can be taken out.
[0005]
[Means for Solving the Problems]
For the purposes achieved, an invention according to claim 1, a cleaning tool for cleaning the inside surface of the water tank, the one surface of the hollow of the cleaning tool body defining a suction chamber therein, a suction write chamber A continuous opening is provided, and the scraper covering the opening is supported on the cleaning tool body so as to be slidable between the first operating position and the second operating position substantially along one surface thereof. A pair of scraping portions slidably in contact with the inner surface of the water tank so as to scrape off deposits such as algae and moss on the inner surface of the water tank are integrally formed on both end edges of the scraping piece in the sliding direction. In the first operating position of the scraper, one scraping portion is in close contact with one side edge of the opening and between the other side edge and the other scraping portion. In the second operation position, the other scraping portion is in close contact with the other side edge so as to form a first slit-shaped gap, and is in front of the one side edge. The cleaning tool body is formed such that a slit-shaped second gap is formed between the cleaning tool and one of the scraping portions, and a suction port to which a suction pipe is connected is opened on the other surface of the cleaning tool body. .
[0006]
The invention according to a second aspect is characterized in that, in addition to the features of the first aspect, the suction port is constituted by a suction cylinder rotatably supported on the other surface of the cleaning tool main body. .
[0007]
[Operation]
According to the configuration of the first aspect of the present invention, in cleaning, the cleaning tool main body or the vicinity of the cleaning tool main body of the suction pipe is grasped while the water suction means such as a water absorption hose is connected to the suction pipe. The scraper is brought into sliding contact with the inner surface of the water tank while one surface (accordingly, the suction port) faces the inner surface of the water tank. As a result, the algae and moss that adhere to and accumulate on the inner surface of the aquarium are efficiently scraped off, and are sucked out from the suction port to the suction chamber, and further to the water absorbing means side. It can be efficiently removed outside the water tank without diffusing into the water tank.
[0008]
That is, in cleaning, the scraping portions at both ends of the scraper are slid against the inner surface of the water tank while one surface of the cleaning tool main body (therefore, the scraping piece) faces the inner surface of the water tank. If the switch is alternately switched between one direction along the sliding direction of the cleaning tool body and the other direction, the scraper automatically shifts to the rear side in the sliding direction due to the sliding resistance each time the switching is performed. (That is, by alternately moving between the first operating position and the second operating position), a gap serving as a suction port can be formed only in front of the scraping portion on the front side in the sliding direction. Thus, when the cleaning tool body is moved in any one of the above-mentioned one direction and the other direction, the algae on the inner surface of the water tank are cooperated with the scraping portion located in the front of the moving direction and the gap corresponding thereto. The moss can be scraped off very efficiently and sucked out to the suction chamber, and eventually to the water absorbing means side.
[0009]
Further, according to the configuration of the second aspect of the present invention, even if the relative position between the main body and the water absorbing means such as the water absorbing hose changes as the cleaning tool main body is moved for cleaning, the change is caused by the change of the suction cylinder. The rotation allows the hose and the like to be easily bent and twisted due to the change in the relative position.

【The invention's effect】
As described above, according to the present invention, with the suction pipe connected to a water absorbing means such as a water absorbing hose, the scraping piece is slid on the inner surface of the water tank while one surface of the cleaning tool body (therefore, the suction port) faces the inner surface of the water tank. When it is brought into contact, the algae and moss that adhere to and accumulate on the inner surface of the water tank can be efficiently scraped off, and can be sucked from the suction port to the suction chamber, and further to the water absorbing means side. Moss and algae can be efficiently removed from the outside of the water tank without diffusing into the water, so that the inside of the water tank can be easily and accurately cleaned without polluting the water.
[0022]
Further Upon sliding contact a surface of Qing掃具body especially the (hence scraping pieces) the cleaning unit of該掻Tohen ends while facing the tank inner surface to the aquarium inner surface, the sliding direction, the scraping member If switching is performed alternately in one direction along the sliding direction with respect to the cleaning tool body and in the other direction, the scraping piece automatically shifts rearward in the sliding direction due to the sliding contact resistance each time the switching is performed, and the sliding is performed. Since a gap serving as a suction port can be generated only in front of the scraping portion on the front side in the tangential direction, even when the cleaning tool body is moved in any one of the above-mentioned one direction and the other direction, it is located closer to the front in the moving direction. in cooperation scraping portion located with the gap corresponding thereto, the aquarium inner surface algae, mosses extremely efficiently scraped by suction chamber, and by extension can be sucked into the water means side, the cleaning effect It can be achieved efficiently.
[0023]
Further, according to the second aspect of the present invention, since the suction port is constituted by the suction tube rotatably supported on the other surface of the cleaning tool main body, the cleaning tool main body is moved for cleaning. Even if the relative position between the main body and the water-absorbing means such as the water-absorbing hose changes, the hose or the like due to the change is effectively avoided by rotating the suction tube in accordance with the change. You.
