Description

【０００１】
【産業上の利用分野】
本発明は、液体を噴出するノズルで、主に自動車のウォッシャ液を噴出するノズルの噴射角度を調節するための治具に関する。
【０００２】
【従来の技術】
従来、自動車のウォッシャ液を運転席側若しくは後部側のガラスに噴射するウォッシャ液噴射ノズル１は、図３に示すように、自動車のボディに取り付けるための取付片３を一体成形したノズルボディ１ａを有し、その両端にウォッシャ液を導入する導入口４とウォッシャ液を噴出する噴出口５とを有し、形成されている。
【０００３】
そして、ウォッシャ液噴射ノズル１における球状噴頭５ａの噴出口５からウォッシャ液が勢い良く噴出され、ガラス面に到達する。
【０００４】
車体に取り付けられるウォッシャ液噴射ノズル１の取付位置が車種によって異なるので、ウォッシャ液が正規の位置に到達するように、予め、球座面で三次元的に回動自在に支持された球状噴頭５ａの噴射角度を、ノズル組み立て後に作業治具上にて設定する。なお、前記ウォッシャ液噴射ノズル１を車体に組込みした後に前記噴射角度の位置合わせをすることもある。
【０００５】
その調整方法は、図４に示すように、例えば金属製の細長い中実な棒状のピン８と、該ピン８の端部に固着された把持部９とを有した治具１０を形成し、前記ピン８の先端部を球状噴頭５ａの噴孔に差し込み、作業者が目見当で噴射角度を調整し、ウォッシャ液を噴出させて確かめ、不都合であれば再びウォッシャ液の噴出を停止して前記ピン８を差し込んで噴射角度を調節し、ウォッシャ液を噴出させて指定角度に設定できるまで調整作業を繰り返していた。
【０００６】
【発明が解決しようとする課題】
しかしながら、このような噴射角度調整方法では、作業者の噴射角度調整の熟練度によって、調整時間が大きく左右されるものであり、ウォッシャ液の噴出を調整の度に繰り返さなければならず、手間が掛かり工期短縮化の障害となっていると言う問題点がある。また、作業者のカンに頼ることが多くて作業能率も向上し難く、作業者に疲労感が生じてストレスが溜まると言う問題点があって、作業環境の改善が望まれている。
【０００７】
このように、従来のノズルの噴射角度調整方法は、作業能率の点において解決すべき課題を有していた。
本発明は、上記の課題に鑑みてなされたもので、作業能率を向上させた噴射角度調整方法と調整用工具の提供を目的とする。
【０００８】
【課題を解決するための手段】
本発明に係るノズルの噴射角度調整方法の上記課題を解決するための要旨は、液体を噴出するノズルの噴出口の噴射角度を調節する工具であって、当該工具の長手方向の両端部が開口された筒状体で、ノズルの噴頭の外筒部へ着脱自在に嵌合される先端側の筒部と、液体を噴出させながら噴射角度を調節できるように前記先端側筒部から拡径させて後端側へ延設させ液体噴出流路から逃がして形成した工具本体とからなるノズルの噴射角度調整用工具を形成し、該工具の先端部をノズルの噴頭に把持させた後に、液体をノズルから噴出させ乍ら、前記工具で噴射角度を調節し、該調節後に液体の噴出を停止して前記工具をノズルの噴頭から取り外すことにある。
【０００９】
本発明に係るノズルの噴射角度調整用工具は、液体を噴出するノズルの噴出口の噴射角度を調節する工具であって、当該工具の長手方向の両端部が開口された筒状体で、ノズルの噴頭の外筒部へ着脱自在に嵌合される先端側の筒部と、液体を噴出させながら噴射角度を調節できるように前記先端側筒部から拡径させ後端側へ延設させ液体噴出流路から逃がして形成した工具本体とからなることである。
【００１１】
【作用】
本発明に係るノズルの噴射角度調整方法によれば、ノズルからウォッシャ液を噴出させ乍らその状態を目視して噴射角度調整ができるようになる。よって、作業者の熟練度に関わり無く、容易に車種に応じた適正な範囲内に噴射角度を調節することができる。
【００１２】
本発明に係るノズルの噴射角度調整用工具によれば、ノズルの噴孔を閉塞させないので、ウォッシャ液を対象物に噴出させながら噴射角度調節ができるようになる。
【００１３】
【実施例】
次に、本発明に係る実施例について図面を参照して詳細に説明する。
本発明の第１実施例は、図１乃至図２に示すように、長手方向の両端部が開口された筒状体で、噴頭５ａの外筒部へ着脱自在に嵌合される先端側の円筒部１１ａと、該先端側円筒部１１ａから拡径させて後端側へ延設させた円筒状の工具本体１１ｂとからなる噴射角度調整用工具１１を形成する。
【００１４】
前記ノズルの噴射角度調整用工具１１は、鋼製その他の金属製であり、強度的に十分であれば硬質の合成樹脂製でも良い。
【００１５】
前記工具本体１１ｂの内径は、ウォッシャ液噴射ノズル１の噴頭５ａから噴出されたウォッシャ液が噴射対象物へと邪魔されずに到達するように、ウォッシャ液噴射流路から逃がして形成する必要があるので、円筒部１１ａの内径よりも漸次拡径させておくものである。但し、どの程度の拡径具合にするかは設計変更的事項である。
【００１６】
また、前記工具本体１１ｂは、作業者がこの噴射角度調整用工具１１を掴んで噴射角度調節するための把持部となるものである。場合によっては、この工具本体１１ｂの外周部にローレットによりあやめ等のきざみ目を設ける様にしても良く、または、当該外周面から突出した調整用腕部を複数個で周方向に設けるようにしても良い。
【００１７】
前記先端側の円筒部１１ａは、噴射角度調整しようとする対象のウォッシャ液噴射ノズル１の噴頭５ａの外筒部に嵌合して把持できるように形成するものである。よって、前記噴頭５ａの外筒部の形状や外径寸法に応じて当該円筒部１１ａの形状等も、円筒形状に限らず例えば楕円形状や矩形状等に適宜に変化するものである。
【００１８】
また、円筒部１１ａの嵌合状態は、前記噴頭５ａの外筒部へ着脱自在になされ、かつ、三次元的に前記外筒部を回動させて噴射角度を調節しなければならないので、隙間の多い遊嵌状態はぐらつくので不適であり、着脱しやすいようにしてなおかつ隙間の少ない遊嵌状態になるよう、円筒部１１ａの内径寸法を設定すべきである。
【００１９】
前記ノズルの噴射角度調整用工具１１によってノズルの噴射角度を調整するには、図２に示すように、ウォッシャ液を噴出しないようにした状態で、前記工具１１を作業者の手で持って、その先端側の円筒部１１ａを、ウォッシャ液噴射ノズル１の噴頭５ａの外筒部に嵌合させ把持させる。
【００２０】
そして、前記工具１１の工具本体１１ｂを手で把持したまま、噴頭５ａからウォッシャ液を噴出させる。
【００２１】
噴出されたウォッシャ液がガラス面の所定の的に当たるように、手を前後左右に動かして噴頭５ａの外筒部を三次元的に回動させる。
【００２２】
そして、所望の噴射角度に調整できたなら、ウォッシャ液の噴出を停止し、そして前記噴射角度調整用工具１１を噴頭５ａの外筒部から取り外す。これによって、ウォッシャ液噴射ノズル１の噴射角度調整作業が完了するものである。
【００２３】
このように、従来の噴射角度調整作業が、ピン８の噴孔への抜き差しとウォッシャ液の噴出の繰り返しであったのが、本発明の方法により、ウォッシャ液を噴出させ乍ら一度で調節が終了し、極めて容易な噴射角度調整作業となったのである。
【００２９】
【発明の効果】
以上説明したように、本発明に係るノズルの噴射角度調整方法は、液体を噴出するノズルの噴出口の噴射角度を調節する工具であって、当該工具の長手方向の両端部が開口された筒状体で、ノズルの噴頭の外筒部へ着脱自在に嵌合される先端側の筒部と、液体を噴出させながら噴射角度を調節できるように前記先端側筒部から拡径させて後端側へ延設させ液体噴出流路から逃がして形成した工具本体とからなるノズルの噴射角度調整用工具を形成し、該工具の先端部をノズルの噴頭に把持させた後に、液体をノズルから噴出させ乍ら、前記工具で噴射角度を調節し、該調節後に液体の噴出を停止して前記工具をノズルの噴頭から取り外すことにしたので、ウォッシャ液の噴射状態を視認しながら噴射角度調整でき１回で調整完了するようになって、噴射角度調整工数が大幅に短縮され、作業能率が向上すると言う優れた効果を奏する。
【００３０】
本発明に係るノズルの噴射角度調整用工具は、当該工具の長手方向の両端部が開口された筒状体で、ノズルの噴頭の外筒部へ着脱自在に嵌合される先端側の筒部と、液体を噴出させながら噴射角度を調節できるように前記先端側筒部から拡径させ後端側へ延設させ液体噴出流路から逃がして形成した工具本体とからなるので、ウォッシャ液等の液体を噴出させながら噴射角度の調整が可能となると言う優れた効果を奏する。

The tip of the pin 8 is inserted into the nozzle hole of the spherical nozzle 5a, the operator adjusts the injection angle with the eye, and confirms by injecting the washer liquid. The pin 8 was inserted to adjust the injection angle, and the adjustment operation was repeated until the washer liquid was jetted and set to the specified angle.
[0006]
[Problems to be solved by the invention]
However, in such an injection angle adjustment method, the adjustment time greatly depends on the skill of the operator in adjusting the injection angle, and it is necessary to repeat the washer liquid ejection for each adjustment. There is a problem that it is an obstacle to shortening the construction period. In addition, there is a problem that work efficiency is difficult to improve because the worker often relies on the operator's can, and there is a problem that the worker feels fatigue and accumulates stress, and improvement of the work environment is desired.
[0007]
Thus, the conventional nozzle injection angle adjusting method has a problem to be solved in terms of work efficiency.
The present invention has been made in view of the above-described problems, and an object thereof is to provide an injection angle adjusting method and an adjusting tool that improve work efficiency.
[0008]
[Means for Solving the Problems]
The gist for solving the above-described problem of the nozzle injection angle adjustment method according to the present invention is a tool for adjusting the injection angle of the nozzle outlet for ejecting liquid, and both longitudinal ends of the tool are open. A cylindrical portion that is detachably fitted to the outer cylindrical portion of the nozzle nozzle, and the diameter of the cylindrical portion is increased from the distal cylindrical portion so that the spray angle can be adjusted while ejecting liquid. Forming a nozzle injection angle adjusting tool that is extended to the rear end side and escaped from the liquid ejection flow path, and holding the tip of the tool at the nozzle head, While ejecting from the nozzle, the ejection angle is adjusted with the tool, and after the adjustment, the ejection of liquid is stopped and the tool is removed from the nozzle head.
[0009]
The nozzle injection angle adjustment tool according to the present invention is a tool for adjusting the injection angle of the nozzle outlet for ejecting liquid, and is a cylindrical body having both ends in the longitudinal direction of the tool opened. A front-end cylinder portion that is detachably fitted to the outer cylinder portion of the nozzle, and a liquid that is expanded from the front-end cylinder portion and extended to the rear end side so that the injection angle can be adjusted while ejecting the liquid. The tool body is formed by escaping from the ejection flow path .
[0011]
[Action]
According to the method for adjusting the injection angle of the nozzle according to the present invention, it is possible to adjust the injection angle by visually observing the state of the washer liquid ejected from the nozzle. Therefore, regardless of the skill level of the operator, the injection angle can be easily adjusted within an appropriate range according to the vehicle type.
[0012]
According to the nozzle injection angle adjusting tool of the present invention, since the nozzle nozzle hole is not blocked, the injection angle can be adjusted while jetting washer liquid onto the object.
[0013]
【Example】
Next, embodiments according to the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, the first embodiment of the present invention is a cylindrical body having both ends in the longitudinal direction opened, and is fitted on the outer cylinder portion of the jet head 5a in a detachable manner. An injection angle adjusting tool 11 is formed which includes a cylindrical portion 11a and a cylindrical tool body 11b having a diameter increased from the front end side cylindrical portion 11a and extended to the rear end side.
[0014]
The nozzle injection angle adjusting tool 11 is made of steel or other metal, and may be made of a hard synthetic resin as long as the strength is sufficient.
[0015]
The inner diameter of the tool main body 11b needs to be formed so as to escape from the washer liquid ejection flow path so that the washer liquid ejected from the nozzle 5a of the washer liquid ejection nozzle 1 reaches the ejection target without being obstructed. Therefore, the diameter is gradually increased from the inner diameter of the cylindrical portion 11a. However, the degree of diameter expansion is a matter of design change.
[0016]
The tool main body 11b serves as a gripping part for an operator to grasp the injection angle adjusting tool 11 and adjust the injection angle. In some cases, the outer periphery of the tool body 11b may be provided with a knurled notch by knurling, or a plurality of adjustment arm portions protruding from the outer peripheral surface may be provided in the circumferential direction. Also good.
[0017]
The cylindrical portion 11a on the distal end side is formed so as to be fitted and gripped with the outer cylinder portion of the nozzle 5a of the washer liquid injection nozzle 1 to be adjusted for the injection angle. Therefore, the shape of the cylindrical portion 11a and the like are not limited to the cylindrical shape and appropriately change to, for example, an elliptical shape or a rectangular shape according to the shape or outer diameter of the outer cylinder portion of the jet head 5a.
[0018]
Further, the fitting state of the cylindrical portion 11a is detachably attached to the outer cylinder portion of the nozzle 5a, and the injection angle must be adjusted by rotating the outer cylinder portion three-dimensionally. The loose fitting state with a large amount is unsuitable because it fluctuates, and the inner diameter dimension of the cylindrical portion 11a should be set so that it is easy to attach and detach and has a small gap.
[0019]
In order to adjust the nozzle injection angle by the nozzle injection angle adjusting tool 11, as shown in FIG. 2, the tool 11 is held by an operator's hand in a state in which the washer liquid is not jetted. The cylindrical portion 11a on the distal end side is fitted into and gripped by the outer cylinder portion of the nozzle 5a of the washer liquid injection nozzle 1.
[0020]
And a washer liquid is jetted from the nozzle 5a, holding the tool main body 11b of the tool 11 by hand.
[0021]
The outer cylinder part of the nozzle 5a is three-dimensionally rotated by moving the hand back and forth and left and right so that the sprayed washer liquid hits the glass surface in a predetermined manner.
[0022]
And if it can adjust to a desired injection angle, ejection of a washer liquid will be stopped and the said tool 11 for injection angle adjustment will be removed from the outer cylinder part of the nozzle 5a. As a result, the operation of adjusting the injection angle of the washer liquid injection nozzle 1 is completed.
[0023]
As described above, the conventional adjustment of the injection angle has been repeated insertion / removal of the pin 8 into / from the nozzle hole and the injection of the washer liquid. It was finished and it became an extremely easy injection angle adjustment work.
[0029]
【The invention's effect】
