[0001] 本発明は、ホースの接続具及び液体用の容器に関し、詳細には、液体貯蔵タンク の補給に際してタンクにホースが必要以上に揷入されず、かつタンクからのホースの 不慮の抜けを防止するようにしたホースの接続具等に関する。  [0001] The present invention relates to a hose connector and a liquid container, and more particularly, when a liquid storage tank is refilled, the hose is not inserted into the tank more than necessary, and the hose is accidentally disconnected from the tank. The present invention relates to a hose connector and the like that are prevented.
背景技術  Background art
[0002] 液体貯蔵タンクに液体を補給するのに使用するものとして、次のような手動給油ポ ンプが知られている。すなわち、手動ポンプ部により灯油の吸排動作を行レ、、排出さ れた灯油を吐出パイプ部を介して石油ストーブ等の内蔵灯油タンクに供給するもの である。このポンプには、吐出パイプ部の先端に係止ストッパ付きのロッドが取り付け られており、吐出パイプ部をタンクに挿入したときに、このストッパにより吐出パイプ部 の必要以上の挿入が阻止される(特許文献 1)。吐出パイプ部の挿入が制限されるこ とで、補給時に吐出パイプ部の先端がタンク内の液体に浸かることを回避し、補給終 了により吐出パイプ部をタンクから引き抜レ、たときに、外面に付着した液体が周囲に 飛び散ることが防止される。また、吐出パイプ部の揷入規制に関し、特許文献 1には [0002] The following manual refueling pumps are known for use in refilling liquid storage tanks. That is, the manual pump unit performs the kerosene intake / exhaust operation, and the discharged kerosene is supplied to the built-in kerosene tank such as an oil stove through the discharge pipe unit. This pump has a rod with a locking stopper attached to the tip of the discharge pipe. When the discharge pipe is inserted into the tank, this stopper prevents the discharge pipe from being inserted more than necessary ( Patent Document 1). By restricting the insertion of the discharge pipe part, the tip of the discharge pipe part is prevented from being immersed in the liquid in the tank during replenishment, and when the discharge pipe part is pulled out of the tank when replenishment is completed, The liquid adhering to the outer surface is prevented from splashing around.

発明の開示  Disclosure of the invention
発明が解決しょうとする課題  Problems to be solved by the invention
[0003] し力、しながら、この手動給油ポンプにおいて、ロッドは、吐出パイプ部の先端に形成 されたロッド圧入部に圧入された状態にあり、内蔵灯油タンクに対する吐出パイプ部 の揷入方向に対し、このロッド圧入部から反対の方向に延伸している。また、ロッドに 取り付けた係止ストッパにより吐出パイプ部の挿入が制限されるものの、この係止スト ッパだけでは、タンクからの吐出パイプ部の抜けに対して充分な接続安定性が得ら れない。 [0003] However, in this manual oil pump, the rod is in a state of being press-fitted into a rod press-fitting portion formed at the tip of the discharge pipe portion, and in the insertion direction of the discharge pipe portion with respect to the built-in kerosene tank. On the other hand, it extends in the opposite direction from this rod press-fit portion. In addition, although the insertion of the discharge pipe is restricted by the locking stopper attached to the rod, sufficient connection stability against the removal of the discharge pipe from the tank can be obtained with this locking stopper alone. I can't.
[0004] ところで、液体貯蔵タンクに補給される液体のための容器として、ホースがその一端 で直接的に接続されたホース一体型のものがある。この容器によれば、液体を容器 に収容したまま貯蔵又は輸送することが可能であり、補給に際しては、ホースの先端 をタンクに揷入し、容器をタンクよりも上方に持ち上げて傾斜させることにより、容器内 の液体をタンクに補給することができる。  By the way, as a container for liquid to be replenished to the liquid storage tank, there is a hose-integrated container in which a hose is directly connected at one end thereof. According to this container, the liquid can be stored or transported while contained in the container. When refilling, the tip of the hose is inserted into the tank, and the container is lifted above the tank and tilted. The liquid in the container can be replenished to the tank.
[0005] し力 ながら、このようなホース一体型の容器については、タンクに対するホースの 挿入が制限されるようなものは見受けられない。ホースの先端に上記係止ストツバ付 きのロッドを取り付けることも考えられる力 このロッドでは、ホースの抜けに対して充 分な接続安定性が得られないことから、容器の持上げ及び傾斜を伴う補給作業によ りタンクが動かされると、ホースが不慮にタンクから抜け、ホース内の液体を周囲にま き散らすおそれがある。他方、上記係止フックによることとしても、使用に際して固定 ボルトを緩めてフックの位置を調節する必要があることから、取扱レ、が面倒である。  [0005] However, there is no such hose-integrated container that restricts the insertion of the hose into the tank. Possible force to attach the rod with the locking stopper to the tip of the hose Since this rod does not provide sufficient connection stability against disconnection of the hose, supply with lifting and tilting of the container If the tank is moved due to work, the hose may accidentally come out of the tank, and the liquid in the hose may be scattered around. On the other hand, even with the above-mentioned locking hook, it is necessary to loosen the fixing bolt and adjust the position of the hook in use, so handling is troublesome.
[0006] 以上から、ホースを介しての液体の補給に際しては、液体貯蔵タンクに対するホー スの挿入が制限されるとともに、タンクからの抜けに対してホースを安定して接続する ことが望まれる。 [0006] From the above, when replenishing liquid through the hose, it is desired that the insertion of the hose into the liquid storage tank is restricted and that the hose is stably connected to the removal from the tank.
課題を解決するための手段  Means for solving the problem
[0007] 本発明は、以上の問題を考慮したホースの接続具及び液体用の容器を提供するも のである。 [0007] The present invention provides a hose connector and a liquid container in consideration of the above problems.
本発明に係る接続具は、ホースを液体貯蔵タンクに着脱可能に接続するものであ つて、ホースの先端を揷入可能な径を有する円環状の基部が設けられる。この基部 力 タンクに対するホースの揷入方向に第 1の係止部が延設される。第 1の係止部に は、基部から所定の間隔の位置に、基部の中心軸に対して外向きに延伸させて外方 突部が形成される。また、基部からホースの揷入方向に前記所定の間隔よりも大きな 値の長さに亘り、可撓性を有する第 2の係止部が延設される。第 2の係止部には、先 端に略 L字状の鉤部が形成される。  The connecting device according to the present invention is a device for detachably connecting the hose to the liquid storage tank, and is provided with an annular base portion having a diameter capable of inserting the tip of the hose. A first locking portion extends in the direction of insertion of the hose into the base force tank. The first locking portion is formed with an outward projecting portion that extends outward with respect to the central axis of the base portion at a predetermined distance from the base portion. Further, a flexible second locking portion is extended from the base in the insertion direction of the hose over a length greater than the predetermined interval. The second locking portion is formed with a substantially L-shaped flange at the front end.
[0008] また、本発明に係る容器は、液体貯蔵タンクに補給される液体のための容器であつ て、液体が収容される容器本体と、容器本体に対して第 1の端部で接続され、この第 1の端部で容器本体の内部と連通するホースと、ホースの第 2の端部に設けられ、こ のホースを、タンクに対してその先端がタンクに所定の長さに亘り挿入された状態で 着脱可能に接続する接続具とを有する。接続具には、タンクのホース挿入孔を形成 する周壁に対して前記挿入状態で当接して、ホースの前記所定の長さを超える長さ に亘るタンクへの揷入を阻止する第 1の係止部と、ホースのタンクから離れる方向へ の移動に対し、ホース揷入孔の周壁と係合してこれを制限する第 2の係止部とが設け られる。 [0008] The container according to the present invention is a container for liquid to be replenished to the liquid storage tank, and is connected to the container main body in which the liquid is stored at the first end with respect to the container main body. This first A hose that communicates with the inside of the container body at the end of 1 and a second end of the hose, and the hose is inserted into the tank for a predetermined length with respect to the tank. And a connecting tool detachably connected. The connector is in contact with the peripheral wall forming the hose insertion hole of the tank in the inserted state to prevent the hose from being inserted into the tank over the predetermined length. A stop portion and a second locking portion that engages and restricts the peripheral wall of the hose insertion hole with respect to the movement of the hose away from the tank are provided.
発明の効果  The invention's effect
[0009] 本発明によれば、ホースを介しての液体の補給に際し、液体貯蔵タンクに対するホ ースの必要以上の挿入が第 1の係止部により阻止されるため、補給時にホースの先 端がタンク内の液体に浸かるのを防止することができる。また、ホースのタンクから離 れる方向への移動が第 2の係止部により制限されるため、タンクからのホースの抜け を防止すること力 Sできる。  [0009] According to the present invention, when the liquid is supplied through the hose, insertion of the hose more than necessary into the liquid storage tank is prevented by the first locking portion. Can be prevented from being immersed in the liquid in the tank. In addition, since the movement of the hose in the direction away from the tank is restricted by the second locking portion, it is possible to prevent the hose from coming out of the tank.
