Description

【０００１】
【発明の属する技術分野】
本発明は、石油ファンヒータ等の石油燃焼機器に使用され、内部に灯油等の石油燃料が収容されるカートリッジ式給油タンクに関する。
【０００２】
【従来の技術】
従来一般に、この種のカートリッジ式給油タンクは、タンク本体の底部の給油口筒にねじ部を設け、この給油口筒に開閉弁装置を備えた給油口キャップをねじ結合することにより、給油口キャップを給油口筒に着脱自在に取り付ける構成であるため、給油時に、給油口キャップに付着している石油燃料が手に着き、手が汚れる欠点があった。
【０００３】
上記したカートリッジ式給油タンクの欠点を解決するために、例えば、特公平６−５６２５９号公報に開示されているように、給油口キャップにキャップ開閉具を被せて給油口キャップの着脱操作を行うことにより、給油時に石油燃料で手が汚れないようにしたものや、例えば、実開昭６０−８１４５５号公報に開示されているように、給油口キャップのネジ部の末端にフランジ部を設け、このフランジ部に回動自在に１つの操作ハンドルを設けることにより、給油時に石油燃料で手が汚れないようにしたものが知られている。
【０００４】
しかしながら、特公平６−５６２５９号公報に開示されたものでは、通常の給油タンクの使用時や、石油ファンヒータ等に使用された場合のシーズンオフ時にには、キャップ開閉具が給油タンクとは離れた位置に置かれる関係上、紛失してしまう心配があり、また、実開昭６０−８１４５５号公報に開示されたものでは、操作ハンドルが一つのため、給油口キャップの着脱操作時に操作ハンドルが揺動し易く不安定であると共に、転倒時に操作ハンドルの先端把持部がタンク本体から側方へはみ出さないようにすると、給油口キャップと操作ハンドルの先端把持部までの距離を十分に確保することができないため、操作ハンドルを掴んだ際に、手が給油口キャップに接触して、手を傷付けたり、石油燃料で手を汚したりする心配があった。
【０００５】
また、従来のものでは、給油口キャップと給油口筒とがネジ結合であるため、給油口キャップを着脱する際には、給油口キャップを一回転以上させる必要があり、給油口キャップの着脱が迅速に行えないものであり、特に、給油口キャップに１つの操作ハンドルを設けたものでは、給油口キャップを一回転以上させる場合、操作ハンドルを何度も持ち替える必要があるため、その持ち替える度に、操作ハンドルがフランジ部側に倒れないように別の手で支えなければならず、片手による簡単操作が行えないものであった。
【０００６】
【発明が解決しようとする課題】
本発明は上述の実情に鑑みてなされたものであり、タンク本体から側方へはみ出さない限られたスペースで、給油口キャップと操作ハンドルの先端把持部との距離を十分な長さとすることができると共に、給油口キャップの着脱操作時における操作ハンドルの不安定さを解消し、給油口キャップを簡単操作で迅速に着脱できるようにすることを目的としている。

【００１２】
【発明の実施の形態】
以下、本発明の一実施形態例を図１ないし図１０に基づき説明する。図において、１は石油ファンヒータ等の石油燃焼機器の外装体内に設置した油受けタンク（図示せず）上に倒立させて油受けタンク内に灯油等の石油燃料を補給するカートリッジ式給油タンク本体であり、このタンク本体１は縦長状に形成され、それの一端側壁面の略中央には、給油口としての円筒状の給油口筒２を突出して設けると共に、前記給油口筒２の基部外周に位置してリング状の係止部材３（係止手段）を設けている。また、図２に示すように、前記係止部材３と給油口筒２との間の環状凹部４には第１環状パッキン５を介挿している。
【００１３】
６は前記給油口筒２に外嵌めされる給油口キャップであり、図２に示すように、この給油口キャップ６はそれの内部に配置した第２環状パッキン７を介して前記給油口筒２の先端部に密接するようになっており、そして、この給油口キャップ６の内部には、給油口キャップ６の流出口６Ａを開閉する開閉弁８と、この開閉弁８を常に弾付勢するスプリング９と、連通孔１０を有する弁収容筒１１とから構成された開閉弁装置１２をカシメ結合によって取り付けている。
【００１４】
１３は前記給油口キャップ６を略中央部分に突出させて配設した基板であり、この基板１３の下面側には、スポット溶接等によって係合片形成リング１４が固着してあり、この係合片形成リング１４には、図２、図９及び図１０に示すように、前記タンク本体１側の係止部材３に係脱自在に係合する一対の係合片１５、１５（係合手段）が内向きに突出して設けられ、これら一対の係合片１５、１５は、前記給油口キャップ６の配設位置の外側に位置して給油口キャップ６と同心的に設けられるとともに、互いに対向して設けられている。
【００１５】
また、前記基板１３には、持ち運び用の取っ手を兼ねると共に給油口キャップ６の着脱操作を行うための第１及び第２操作ハンドル１６、１７が、互いに前記給油口キャップ６側にのみ起伏するように起伏自在に設けられており、これら二つの操作ハンドル１６、１７は、左右両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａの先端部に先端把持部１６Ｂ、１７Ｂを有し、それぞれ径が約４ｍｍで断面円形の金属線材にて略コ字状に折曲加工されている。
【００１６】
前記第１操作ハンドル１６の両側辺部１６Ａ、１６Ａの基端には、互いに内向きに折曲加工された枢軸部１６Ｃ、１６Ｃが設けられ、一方、前記第２操作ハンドル１７の両側辺部１７Ａ、１７Ａの基端には、互いに外向きに折曲加工された枢軸部１７Ｃ、１７Ｃが設けられている。また、図５に示すように、前記第１操作ハンドル１６と第２操作ハンドル１７は、それぞれの先端把握部１６Ｂ、１７Ｂの長さ寸法１Ｓ、２Ｓが略同等であり、枢軸部１６Ｃ、１７Ｃから先端把握部１６Ｂ、１７Ｂまでの左右両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａの幅寸法１Ｔ、２Ｔは、第１ハンドル１６よりも第２ハンドル１７の方が大きく設定され、互いに異ならせてある。
【００１７】
前記第１及び第２操作ハンドル１６、１７は、前記給油口キャップ６を略中心として基板１３の外縁部の４箇所に基板１３と一体成形にて立設した立片１８、１８、１９、１９（ハンドル保持部）に回動可能に保持され、先端把握部１６Ｂ、１７Ｂの長さ寸法１Ｓ、２Ｓを互いに略同等として、両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａの幅寸法１Ｔ、２Ｔを互いに異ならせることにより、起立時の交差状態が解除されないようになっており、また、図１、図２及び図６に示すように、起立時の交差状態においては、第１操作ハンドル１６の先端把持部１６Ｂの傾斜した左右の根本部イ、イに、第２操作ハンドル１７の両側辺部１７Ａ、１７Ａの上部が突き当り、互いの先端把握部１６Ｂ、１７Ｂが近接した状態となり、転倒時には、図４に示すように、基板１３の上面側に沿って互いに略水平状態となり、起伏いずれの状態でも給油口キャップ６は接触しない。
【００１８】
前記各立片１８、１９は、枢軸部１６Ｃ、１７Ｃが挿入される孔（符号を付与せず）を有すると共に、図４に示すように、第１及び第２操作ハンドル１６、１７の起伏回動角度Ｘを９０度以内（実施形態例では約８５度）に制限する制限手段としての突き当り部１８Ａ、１９Ａが設けられている。そして、これら立片１８、１８、１９、１９には、前記第１及び第２操作ハンドル１６、１７の両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａの下部がそれのスプリングバックによるバネ力で圧接し、第１及び第２操作ハンドル１６、１７が自立するようになっている。また、前記係止部材３は、図２、図６、図７及び図８に示すように、タンク本体１へ取り付けるための環状取付壁２０と、この環状取付壁２０の外周縁から立ち上げられた環状立壁２１と、この環状立壁２１の上縁から外向き水平に設けられた上面壁２２と、この上面壁２２の外周縁から垂下した垂下側壁２３とを一体成形してなるものである。
【００１９】
前記係止部材３の上面壁２２には、係合片形成リング１４の係合片１５、１５が通過する大きさの一対の切欠２４、２４が対称位置に設けられ、また、前記垂下側壁２３の対称位置には、前記切欠２４に連続して垂下側壁２３の一部を所定高さ及び所定幅にわたって除去することにより垂下側壁２３の上部に形成した係止壁部２３Ａと、この係止壁部２３Ａの一端部分に形成したストッパー溝２５が設けられている。
【００２０】
図７に示すように、切欠２４を通過して上面壁２２の下側に押し込まれた係合片１５は、切欠２４の位置から時計方向に略９０度回動すると、それの一部が前記ストッパー溝２５に入り込んで停止し、係止壁部２３Ａに確実に係止される。即ち、係止部材３と係合片１５との係脱回動角度θは略９０度に設定されている。
【００２１】
上記構成において、タンク本体１に石油燃料を給油する給油時には、図１に示す状態のように、第１及び第２操作ハンドル１６、１７を起立させ、接近した状態の操作ハンドル１６、１７の先端把持部１６Ｂ、１７Ｂを片手で掴んで、図１で示す状態から略９０度、反時計方向に操作ハンドル１６、１７を回動させる。すると、操作ハンドル１６、１７の回動に伴って基板１３が反時計方向に回動し、ストッパー溝２５に入り込んでいた係合片形成リング１４の係合片１５が、係止部材３の切欠２４の所まで移動して切欠２４に対向した状態となる。そこで、前記操作ハンドル１６、１７を持ち上げると、係合片１５が切欠２４を通過して、基板１３及び給油口キャップ６がタンク本体１から離れ、図５に示すように、タンク本体１の給油口筒２が開口され、給油ポンプ等を用いて、給油口筒２から石油燃料を供給すれば良い。
【００２２】
タンク本体１内への石油燃料の給油が終了したら、再び前記操作ハンドル１６、１７の先端把持部１６Ｂ、１７Ｂを掴んで、給油口キャップ６をタンク本体１の給油口筒２に嵌合させる。その状態で、図示しないタンク本体１側の目印と基板１３側の目印とを合致させると、係合片１５が切欠２４に対応してその切欠２４を通過し、その後、操作ハンドル１６、１７を時計方向に略９０度、回動させる。
【００２３】
上述の操作ハンドル１６、１７の略９０度の回動に伴って、前記係合片１５はそれの一部が係止部材３のストッパー溝２５に入り込み、図２に示すように、第２環状パッキン７を介して給油口キャップ６が給油口筒２に密接し、さらに、基板１３の下面も第１環状パッキン５に圧接することになり、燃料漏れは二重に防止される。また、操作ハンドル１６、１７は、時計方向、反時計方向への約４分の１回転の回動操作で給油口キャップ６の着脱が行えるため、手を持ち替えずに済む。
【００２４】
給油口キャップ６の取り付けが終了したら、操作ハンドル１６、１７を取っ手として利用し、操作ハンドル１６、１７を手で持って、タンク本体１を石油燃焼機器の所に持ち運ぶ。この時、操作ハンドル１６、１７を取っ手として利用すると、給油口キャップ６が上向きとなるため、持ち運び中に、給油口キャップ６に付着した石油燃料を床面等に滴下させないようにできる。
【００２５】
持ち運ばれたタンク本体１は、給油口キャップ６が下向きになるように逆にして石油燃焼機器のタンク収容室（図示せず）に収容する。このタンク収容室への収容時には、図４に示すように、操作ハンドル１６、１７は、基板１３に沿って互いに水平状態となるようにすれば良い。タンク収容室への収容状態時には、給油口キャップ６の先端のみが石油燃料に接触し、基板１３や操作ハンドル１６、１７には石油燃料が接触しない。また、操作ハンドル１６、１７は、それらの先端把持部１６Ｂ、１７Ｂを片手で握った状態で、手が給油口キャップ６に接触することのない高さ寸法となっている。そのため、給油口キャップ６に付着した石油燃料に手が触れることもない。
【００２６】
本実施形態例によれば、給油口キャップ６及びタンク本体１側の係止部材３に係合させる係合片１５、１５を備えて、タンク本体１に係脱自在に係着される基板１３に、持ち運び用の取っ手を兼ねると共に給油口キャップ６の着脱操作を行うための第１及び第２操作ハンドル１６、１７を互いに給油口キャップ６側にのみ起伏自在となるように設けた構成としているので、操作ハンドル１６、１７は、図３に示すように、所在箇所がタンク本体１の一端側の狭いスペースでありながら、転倒時にそれらの各先端部がタンク本体１の側方へはみ出すことがなく、しかも、起立時においては、図２に示すように、それらの先端把持部１６Ｂ、１７Ｂと給油口キャップ６との距離を十分長く確保することが可能となる。従って、給油口キャップ６の着脱操作の際や、タンク本体１を持ち運ぶ際に、先端把持部１６Ｂ、１７Ｂを掴んだ手が、給油口キャップ６に接触する心配がなく、給油口キャップ６の先端に手を接触させて傷付けたり、石油燃料で手を汚したりする事態を未然に防止できるばかりでなく、起立時に、第１及び第２操作ハンドル１６、１７が互いに交差して、４点支持状態の操作ハンドルとなるので、これら第１及び第２操作ハンドル１６、１７の先端把持部１６Ｂ、１７Ｂを片手で同時に掴むことで、一つの操作ハンドルによる不安定さが解消され、給油口キャップ６の着脱操作時における操作ハンドルの安定性を確保できる。
【００２７】
また、給油口キャップ６を設けた基板１３側の係合片１５を、給油口筒２を設けたタンク本体１側の係止部材３に係合、或るいは離脱させることにより、ネジ結合を用いずに、給油口キャップ６を着脱できるので、給油口キャップ６の着脱操作を迅速となせる。
【００２８】
また、前記第１及び第２操作ハンドル１６、１７は、金属線材を略コ字状に折曲加工してなるものであるから、両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａに枢軸部１６Ｃ、１６Ｃを一体に成形できて、枢支構造の簡素化が図れる等、コスト面で有利である。
【００２９】
また、前記第１及び第２操作ハンドル１６、１７は、先端把握部１６Ｂ、１７Ｂの長さ寸法１Ｓ、２Ｓを互いに略同等とし、両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａ間の幅寸法１Ｔ、２Ｔを互いに異ならせ、起立時の交差状態が解除されない構成としているので、起立時においては、第１操作ハンドル１６の先端把持部１６Ｂの根本部イ、イに第２操作ハンドル１７の両側辺部１７Ａ、１７Ａが突き当たり、この突き当りによって、先端把持部１６Ｂ、１７Ｂ間に略一定の距離を保つことができるため、操作ハンドル１６、１７は最適状態の握り幅が確保されることになり、着脱操作時や運び時における指への負担を軽減できる。
【００３０】
また、前記基板１３に立設した各立片１８、１９には、第１及び第２操作ハンドル１６、１７の起伏回動角度Ｘを９０度以内に制限する制限手段としての突き当り部１８Ａ、１９Ａを設けた構成としているので、先端把持部１６Ｂ、１７Ｂを掴んだ状態での操作ハンドル１６、１７の揺動範囲を極力小さくすることが可能となり、持ち運び時のタンクの振れが抑えられる。
【００３１】
また、前記各立片１８、１９には、前記第１及び第２操作ハンドル１６、１７の両側辺部１６Ａ、１６Ａ、１７Ａ、１７Ａの下部がそれのスプリングバックによるバネ力で圧接し、第１及び第２操作ハンドル１６、１７がそれぞれ自立するようになっているので、起立させた各操作ハンドル１６、１７は、転倒せずにその起立状態が保たれるため、二つの操作ハンドル１６、１７を備えながら、ハンドル操作が片手で行え、使い勝手を高めることができる。
【００３２】
また、タンク本体１側の係止部材３と基板１３側の係合片１５との係脱回動角度θを略９０度に設定したことにより、手を持ち替えずに、約４分の１回転で給油口キャップ６を着脱でき、給油口キャップ６の着脱操作が簡便となり、使い勝手が良好となる。
【００３３】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cartridge-type refueling tank used for oil-burning equipment such as an oil fan heater and containing petroleum fuel such as kerosene therein.
[0002]
[Prior art]
Conventionally, in general, this type of cartridge type refueling tank is provided with a screw portion in a refueling port cylinder at the bottom of the tank body, and a refueling port cap provided with an opening / closing valve device is screwed to the refueling port cylinder to form a refueling port cap. Is removably attached to the fuel filler tube, so that when fueling, there is a disadvantage that petroleum fuel attached to the fuel filler cap arrives at the hand and gets dirty.
[0003]
In order to solve the above-mentioned drawbacks of the cartridge type refueling tank, for example, as disclosed in Japanese Patent Publication No. 6-56259, it is necessary to cover the refueling port cap with a cap opening / closing device and to perform the mounting and dismounting operation of the refueling port cap. In this way, a hand is prevented from being stained with petroleum fuel at the time of refueling. For example, as disclosed in Japanese Utility Model Unexamined Publication No. 60-81455, a flange portion is provided at the end of a screw portion of a fuel filler cap. It is known that one operation handle is rotatably provided on a flange portion so that hands are not stained with petroleum fuel during refueling.
[0004]
However, in the device disclosed in Japanese Patent Publication No. 6-56259, the cap opening / closing device is separated from the fuel tank when the normal fuel tank is used or when the season is off when the fuel tank is used for an oil fan heater or the like. There is a concern that the operation handle may be lost due to being placed in a position where it is placed, and the operation handle disclosed in Japanese Utility Model Laid-Open Publication No. 60-81455 has only one operation handle. It is easy to swing and unstable, and when the tip handle of the operation handle does not protrude sideways from the tank body when falling, sufficient distance between the filler cap and the tip handle of the operation handle is secured. When the operation handle is grasped, there is a concern that the hand may come into contact with the filler cap when the operation handle is grasped, thereby damaging the hand or soiling the hand with petroleum fuel.
[0005]
Also, in the conventional type, since the filler cap and the filler cylinder are screw-connected, it is necessary to rotate the filler cap at least once when attaching or removing the filler cap. This cannot be done quickly, especially when the filler cap is provided with one operation handle.When the filler cap is rotated more than once, it is necessary to change the operation handle many times. However, the operation handle must be supported by another hand so as not to fall down to the flange portion side, so that simple operation with one hand cannot be performed.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described circumstances, and has a sufficient length of a distance between a fuel filler cap and a distal end grip portion of an operation handle in a limited space that does not protrude sideways from a tank body. It is another object of the present invention to eliminate the instability of the operation handle at the time of attaching / detaching the filler cap, and to enable quick attachment / detachment of the filler cap by simple operation.
