Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、ガソリンスタンド等の給油所に設置される給
油装置に関する。TECHNICAL FIELD The present invention relates to an oil supply device installed in an oil supply station such as a gas station.
［従来の技術］ 周知の如く、給油所に設置される給油装置には、給油し
ようとする自動車の燃料タンクの給油口に挿入する給油
ノズルに給油ホースが接続されている。例えば給油口に
給油ノズルを挿入したままで誤って自動車が走行した場
合に、給油ホースが切断されて、油をまき散らすと危険
であるから、一定の引張力が給油ホースに印加される
と、自動的に分離してかつ流路を閉じる安全管接手が給
油ホースに取付けられている。[Prior Art] As is well known, a fueling hose is connected to a fueling device installed at a fueling station, to a fueling nozzle inserted into a fueling port of a fuel tank of an automobile to be refueled. For example, if a car accidentally runs while the fuel nozzle is still inserted in the fuel filler port, it is dangerous to cut the fuel hose and sprinkle the oil.Therefore, if a certain tensile force is applied to the fuel hose, A safety pipe joint is attached to the refueling hose to separate it and close the flow path.
［従来技術の問題点］ しかしながら、一般に給油ホースは、通常、ゴムを主体
とする材料を用いているので、安全管接手に分離する程
度の引張力（200kg前後）がかかると、長さが法令で3m
と決められている給油ホースは1m以上延び、約4mの長さ
になる。この状態で安全管接手が分離すると、上記の伸
びが縮むことにより給油ホースと給油ノズルがふっと
び、作業員に当ると、危険であり、自動車又は給油装置
に当ると、これらが破損する。[Problems of the prior art] However, since the refueling hose is usually made of a material mainly made of rubber, if the pulling force (about 200 kg) is applied to the safety pipe joint to the extent that it separates, the length becomes legal. At 3m
The refueling hose, which has been determined to be, extends for more than 1 m and is about 4 m long. If the safety pipe joint is separated in this state, the expansion hose will cause the refueling hose and the refueling nozzle to float, causing a risk of hitting a worker and damaging them when hitting an automobile or a refueling device.
したがって、上記の危険および破損を避けるために安全
管接手が分離する分離引張力を人間が普通に引張っても
分離しない程度の値、例えば50kgぐらいに小さくするこ
とが考えられるが、その程度に小さくすると、ポンプを
作動したときや給油ノズルのノズルス弁を閉じたときの
圧力上昇の繰返しにより安全管接手が分離してしまう。Therefore, in order to avoid the above dangers and damages, it is conceivable to reduce the separation tension force that the safety pipe joint separates to a value that does not separate even if a person normally pulls it, for example, about 50 kg, but it is small to that extent. Then, the safety pipe joint is separated due to repeated pressure increase when the pump is operated or when the nozzle valve of the oil supply nozzle is closed.
また、従来安全管接手は給油ホース取付部、すなわち給
油装置の本体ケース側に設けられ、給油ホース取付部は
本体ケースの側面に設けられているので、給油位置によ
っては安全管接手に分離方向の引張力が作用せずに、斜
め方向の力が作用し、適正値で分離できなくなり、また
場合によっては給油装置を倒してしまう。Further, since the safety pipe joint is conventionally provided on the refueling hose mounting portion, that is, on the body case side of the lubrication device, and the refueling hose mounting portion is provided on the side surface of the body case, the safety pipe joint may be separated depending on the refueling position. The tensile force does not act, but the diagonal force acts, and it becomes impossible to separate at an appropriate value, and in some cases the refueling device is tilted.
一般に給油ホースが伸びるとその張力によって分離する
安全管接手は種々知られており、例えば実開昭61−5630
0号公報、特開昭58−183494号公報等に開示されてい
る。しかしながら、これらの公知技術では前述の通り、
大きい張力が安全管接手の分離により瞬間的に零になる
と、給油ホースが飛びはねて危険であり、また斜め方向
の力がかかった場合に軸線方向のベクトル値が小さいと
安全管接手が分離されないという欠点がある。Generally, there are various known safety pipe joints that separate when the refueling hose expands due to the tension of the hose.
No. 0, JP-A-58-183494 and the like. However, in these known technologies, as described above,
If a large tension momentarily becomes zero due to the separation of the safety pipe joint, the refueling hose will fly off, which is dangerous, and if a force in the diagonal direction is applied, the safety pipe joint will separate if the vector value in the axial direction is small. There is a drawback that it is not done.
［解決しようとする課題］ したがって、本発明の目的は、給油ホースの張力とは無
関係に所定の伸びが生じた場合に安全管接手が分離する
給油装置を提供するにある。[Problem to be Solved] Therefore, an object of the present invention is to provide an oil supply device in which a safety pipe joint is separated when a predetermined extension occurs regardless of the tension of an oil supply hose.

値に達するとたるみがなくなる寸法になっている。[Means for Solving the Problems] According to the present invention, the refueling hose (H) is connected to the discharge pipe via the swivel (S), and the safety pipe joint (1) is provided at the tip of the refueling hose (H). The refueling nozzle (N) is connected through the safety pipe joint (1), and the safety pipe joint (1) is slidably fitted to the one joint (3) and the other joint (5). The foot portion (9a) of the valve body (9) is slidably inserted inside, and the engagement ball (6) is provided in the accommodation hole (7) of one joint (3), and the foot portion (9a) is provided. With locking ball (6)
Engages with the engaging recess (8) of the other joint (5),
The valve body (9) is attached to one joint (3) by a spring (10).
In the refueling device that is pressed to the side, one end (20a) of the string-like body (20) that does not extend is fixed to the end of the refueling hose (H) on the swivel (S) side. (2
The other end (20b) of (0) is connected to a pin (21) provided on the valve body (9), and the cord-like body (20) has a slack longer than the length of the oil supply hose (H), When the elongation of (H) reaches a predetermined value, the slack disappears.

このように両接手が分離されると、弁体はばねの作用で
他方の接手の弁座に着座して閉塞するので、油がまき散
らされることはない。[Explanation of Action and Effect] Therefore, for example, when the vehicle runs by mistake during refueling, if the refueling hose extends and the slack of the string-shaped body disappears,
The string pulls the valve body against the spring via the pin. Then, the foot of the valve body does not lock the locking ball, and the locking ball comes out of the housing hole 7, so that both joints are separated.
When the two joints are separated in this way, the valve body is seated on the valve seat of the other joint and closed by the action of the spring, so that the oil is not sprinkled.
このように本発明によれば、給油ホースの張力ではなく
て伸びを検知して、所定量の伸びによって確実に両手が
分離するので、給油ホースが折れ曲った状態で給油して
いても適正値で分離する。Thus, according to the present invention, the extension is detected instead of the tension of the refueling hose, and the two hands are reliably separated by the predetermined amount of extension. Therefore, even if the refueling hose is refueled in a bent state, an appropriate value can be obtained. Separate with.
また給油ホースの張力が大とならないように分離するの
で、分離時に張力が解放されて給油ホースが飛びはねる
ことがなく安全である。Further, since the refueling hose is separated so as not to have a large tension, the tension is not released at the time of separation, and the refueling hose does not jump and is safe.
