【産業上の利用分野】[Industrial application]

この考案は、空気充填器に関し、詳しくは、自動車用タイヤの空気チューブ等 に圧力空気を充填するために用い、圧力空気源に接続されたホース等の先端に取 り付けられて、空気チューブ等に備えられたバルブ金具に連結して使用する空気 充填器に関するものである。 The present invention relates to an air filling device, and more specifically, it is used for filling an air tube or the like of an automobile tire with pressurized air, and is attached to a tip of a hose or the like connected to a pressure air source to obtain an air tube or the like. The present invention relates to an air filling device which is used by being connected to a valve fitting provided in the.

【0002】[0002]

【従来の技術】[Prior Art]

従来、自動車用タイヤの空気チューブに空気を充填するには、空気チューブに 設けられた細い管状のバルブ金具に、コンプレッサ等に連結されたエアホースの 先端に設けられた空気充填器の先端を押し当てて、圧力空気を空気チューブに送 り込むようになっている。 Conventionally, in order to fill the air tube of an automobile tire with air, the tip of an air filling device provided at the tip of an air hose connected to a compressor is pressed against a thin tubular valve fitting provided on the air tube. The compressed air into the air tube.

【0003】 バルブ金具は、通常の状態では、バルブコア等と呼ばれる作動弁機構で閉塞さ れていて、内部の圧力空気が逃げないようになっている。また、空気充填器にも 作動弁機構が内蔵されていて、バルブ金具に装着しない状態では、空気充填器か ら圧力空気が噴出しないようになっている。そして、バルブ金具に空気充填器を 押し当てると、空気充填器に内蔵された作動弁機構とバルブ金具の作動弁機構と が互いに当接して作動し、弁を開く結果、空気充填器からバルブ金具へと圧力空 気が流れ込むようになっている。空気チューブに圧力空気が充填された後は、バ ルブ金具の先端にバルブキャップを取り付けて、バルブ金具に異物が入り込んだ り、バルブ金具が誤って開いたりすることがないようにしておく。このバルブキ ャップを取り付けるために、バルブ金具の外周には雄ねじが切ってあり、バルフ キャップの内周に切られた雌ねじをねじ込むようになっている。In a normal state, the valve fitting is closed by an actuating valve mechanism called a valve core or the like so that the pressurized air inside does not escape. The air filling device also has a built-in valve mechanism that prevents pressurized air from being ejected from the air filling device when it is not attached to the valve fitting. When the air filler is pressed against the valve fitting, the operating valve mechanism built into the air filler and the operating valve mechanism of the valve fitting come into contact with each other to operate, and as a result, the valve is opened. The pressure air is flowing into. After the air tube is filled with pressurized air, attach the valve cap to the end of the valve fitting to prevent foreign matter from entering the valve fitting and accidentally opening the valve fitting. To attach this valve cap, a male thread is cut on the outer circumference of the valve fitting, and a female thread cut on the inner circumference of the valve cap is screwed in.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところが、上記のような従来の空気充填器では、空気チューブに圧力空気を送 り込んでいる間は、常に、空気充填器をバルブ金具に押し当てておかなければな らず、大変に手間がかかるという問題があった。 空気充填器とバルブ金具は、互いの作動弁機構が押し合うことによって、弁を 開くようになっているので、空気充填器をバルブ金具に強く押し付けていないと 、作動弁機構が閉じてしまい、空気充填器からバルブ金具に圧力空気が流れ込ま なくなるのである。また、空気充填器からバルブ金具へは、高圧の空気が通過し ているので、この圧力空気が外部に逃げ出そうとして、空気充填器とバルブ金具 とを互いに離す方向に力が作用している。したがって、空気充填器をバルブ金具 に押し当てる力は、かなり大きな力を必要とし、この押し当てが緩むと、空気充 填器とバルブ金具の隙間から圧力空気が漏れ、その反動で、空気充填器がバルブ 金具から外れてしまうことになる。空気充填器がバルブ金具から外れたときに、 空気充填器から噴出する圧力空気の反動で、空気充填器あるいはエアホースが跳 ね飛んでしまい、作業者が怪我をしたり、周囲の物を損傷する危険性もある。 However, in the above-described conventional air filling device, the air filling device has to be constantly pressed against the valve fitting while the compressed air is being sent to the air tube, which is very troublesome. There was a problem of this. The air filling device and the valve fitting open the valve by the operation valve mechanism pressing each other, so if the air filling device is not strongly pressed against the valve fitting, the operation valve mechanism will close. The pressurized air will no longer flow from the air filler to the valve fitting. Further, since high-pressure air passes from the air filling device to the valve fitting, a force acts in a direction in which the air filling device and the valve fitting are separated from each other so that the pressurized air tries to escape to the outside. Therefore, the force that presses the air filler against the valve fitting requires a considerably large force, and if this pushing becomes loose, pressure air leaks from the gap between the air filler and the valve fitting, and as a reaction, the air filler Will come off the valve fittings. When the air filling device comes off the valve fitting, the air filling device or the air hose bounces off due to the reaction of the pressure air ejected from the air filling device, which may injure the operator or damage surrounding objects. There is also a danger.

【0005】 上記のような問題を解決するため、空気充填器の先端に、クリップ状の係合機 構を設けておいて、この係合機構で空気充填器をバルブ金具に固定する方法が提 案されている。 しかし、このようなクリップ状の係合機構は、爪状の係合片をバルブ金具の外 周に局部的に引っ掛けて固定するので、バルブ金具の雄ねじが潰れてバルブキャ ップが取り付けられなくなったり、バルブ金具が局部的に変形したり損傷したり する問題が生じる。また、爪状の係合片などは、機械的強度や耐久性に劣るため 、繰り返し使用しているうちに、空気充填器をバルブ金具に固定出来なくなった り、取り扱い中に係合機構の摺動部分や軸受部分などが損傷して使用できなくな ることが多い。また、空気充填器の先端をバルブ金具に押し当てるだけでなく、 空気充填器の先端に設けられたクリップ等を操作する必要があるため、前記した ように、空気充填器をバルブ金具に押し当てるだけのものに比べて、作業が面倒 である。しかも、タイヤの構造あるいは取付状態によっては、空気チューブに設 けられたバルブ金具の位置が、作業者の手が届き難い場所であった場合には、前 記のような複雑な手動操作の必要な係合機構は採用することができない。具体的 には、トラックのダブルタイヤの空気チューブに装着状態のままで空気を充填し たい場合、ダブルタイヤの奥側に配置された空気チューブのバルブ金具の位置ま で、作業者の手あるいは指先を届かせて係合機構を操作することは不可能に近い 。In order to solve the above problems, a method has been proposed in which a clip-shaped engagement mechanism is provided at the tip of the air filling device and the air filling device is fixed to the valve fitting by this engagement mechanism. Is being proposed. However, in such a clip-shaped engagement mechanism, the claw-shaped engagement piece is locally hooked and fixed to the outer circumference of the valve fitting, so that the male screw of the valve fitting is crushed and the valve cap cannot be attached. This causes a problem that the valve fitting is locally deformed or damaged. In addition, since the claw-shaped engaging pieces are inferior in mechanical strength and durability, it becomes impossible to fix the air infuser to the valve fitting after repeated use, or the engaging mechanism slides during handling. The moving parts and bearings are often damaged and unusable. In addition to pressing the tip of the air filler against the valve metal fitting, it is necessary to operate the clip etc. provided on the tip of the air filler, so press the air filler against the valve metal fitting as described above. It's more troublesome than just the ones. In addition, depending on the tire structure or mounting condition, if the position of the valve fitting on the air tube is difficult for the operator to reach, complicated manual operation as described above may be necessary. No such engagement mechanism can be adopted. Specifically, if you want to fill the air tube of the double tire of the truck with air while it is still attached, the operator's hand or fingertip up to the valve fitting of the air tube located on the back side of the double tire. It is almost impossible to operate the engaging mechanism by reaching the position.

【0006】 そこで、この考案の課題は、空気の充填作業中、常に空気充填器をバルブ金具 に押し当てていなくても、空気充填器がバルブ金具から外れることがないように 一時的に固定しておけるとともに、空気充填器をバルブ金具に固定したり固定解 除したりする作業が簡単であり、圧力空気の充填作業の簡略化および能率向上を 図ることのできる空気充填器を提供することにある。Therefore, an object of the present invention is to temporarily fix the air filling device so that it will not come off from the valve fitting even if the air filling device is not always pressed against the valve fitting during the air filling operation. In addition, it is easy to fix and release the air filling device to the valve fitting, and to provide an air filling device that simplifies the work of filling pressurized air and improves efficiency. is there.

【課題を解決するための手段】[Means for Solving the Problems]

上記課題を解決する、この考案にかかる空気充填器は、外周に雄ねじが切られ たバルブ金具に圧力空気を供給する空気充填器において、空気充填器の先端に取 り付けられた口金が、バルブ金具の雄ねじ外径よりも大きな内径を有する装着穴 を備え、この装着穴の内周には、バルブ金具に対して口金を傾けたときにバルブ 金具の雄ねじに噛み合う凹凸溝を備えている。 The air filling device according to the present invention, which solves the above-mentioned problems, is an air filling device that supplies pressurized air to a valve fitting having an external thread on the outer circumference.The base attached to the tip of the air filling device is The mounting hole has an inner diameter larger than the outer diameter of the male thread of the metal fitting, and the inner periphery of the mounting hole is provided with an uneven groove that meshes with the male thread of the valve metal fitting when the base is tilted with respect to the valve metal fitting.

【0008】 まず、この考案の空気充填器を使用するバルブ金具は、管状のバルブ金具本体 と、バルブ金具本体の内部に作動弁機構いわゆるバルブコアを組み込んだ構造の ものであって、バルブ金具本体の先端外周には雄ねじが切られている。このよう なバルブ金具の構造や雄ねじの口径、ピッチなどは、JISその他の各種の規格 で決められており、この考案は、このような規格寸法を有する通常のバルブ金具 にそのまま適用できる。First, the valve fitting using the air filling device of the present invention has a structure in which a tubular valve fitting main body and an operating valve mechanism, a so-called valve core, are incorporated in the valve fitting main body. A male screw is cut on the outer circumference of the tip. The structure of such a valve fitting, the diameter of the male screw, the pitch, etc. are determined by JIS and various other standards, and the present invention can be applied as it is to an ordinary valve fitting having such standard dimensions.

【0009】 空気充填器の基本的な構造は、通常のバルブ金具に使用される空気充填器と同 様である。具体的には、コンプレッサ等の圧力空気源につながれたエアホースを 接続する継手部、作業者が手で持ったり操作したりする際につかむ操作部、バル ブ金具に装着するヘッド部、および、ヘッド部の先端に取り付けられ、バルブ金 具と直接に接触する口金などを備えている。操作部とヘッド部の間に、延長軸部 を介しておけば、操作部とヘッド部の距離を自由に設定することができ、近寄り 難い場所にあるバルブ金具に対しても圧力空気の充填作業が行えるようになる。 また、操作部とヘッド部の構成角度、あるいは口金の取付角度を適当に設定して おけば、これらの部分が直線上に並んでいるだけでは作業が困難な場所のバルブ 金具にも使用することができる。The basic structure of the air filling device is the same as that of the air filling device used for a normal valve fitting. Specifically, a joint that connects an air hose connected to a compressed air source such as a compressor, an operating part that is gripped when an operator holds or operates it by hand, a head part that is attached to a valve fitting, and a head. It is equipped with a mouthpiece that is attached to the tip of the part and that directly contacts the valve fitting. If an extension shaft is provided between the operating part and the head part, the distance between the operating part and the head part can be set freely, and pressure air can be filled even in valve fittings that are difficult to access. Will be able to. Also, if the operating angle and head angle, or the attachment angle of the mouthpiece, are set appropriately, it can be used for valve fittings in places where it is difficult to work by simply arranging these points in a straight line. You can

【0010】 空気充填器のヘッド部には、前記したように、バルブ金具に装着しないときに 圧力空気が漏れないようにしたり、バルブ金具に装着したときにバルブ金具の作 動弁機構を作動させたりする作動弁機構を内蔵しており、このような作動弁機構 の先端に、バルブ金具の先端に嵌め込む口金を備えている。ヘッド部としては、 バルブ金具への装着部分すなわち前記作動弁機構や口金を1組だけ、あるいは、 複数組備えたものを用いることができる。As described above, the head portion of the air filling device prevents the pressure air from leaking when it is not attached to the valve fitting, or operates the valve fitting operating valve mechanism when it is attached to the valve fitting. It also has a built-in actuating valve mechanism, and the tip of such actuating valve mechanism is equipped with a base that fits into the tip of the valve fitting. As the head portion, it is possible to use a portion to be attached to the valve metal fitting, that is, one having one set of the actuating valve mechanism and the mouthpiece, or a plurality of sets.

【0011】 口金は、概略円筒状もしくは中空円盤状をなしている。口金は、前記ヘッド部 に一体形成されていてもよいが、ヘッド部とは別個に作製されていて、ねじ込み 、あるいは係合などの手段でヘッド部に着脱自在に取り付けられるようになって いるものが製造および取り扱いに好ましい。口金をヘッド部にねじ込み固定する 場合、口金の外周に、スパナやレンチ等の工具で回動操作できる工具嵌合部を設 けておけば、作業が行い易い。工具嵌合部は、通常の金具と同様に、六角ナット 状のものや、その他の多角形あるいは凹凸形状を備えたものが利用できる。工具 嵌合部としては、口金の先端面に直径方向の溝や凹凸などを形成しておくもので もよい。The base has a substantially cylindrical shape or a hollow disk shape. The base may be formed integrally with the head part, but is manufactured separately from the head part and is detachably attached to the head part by means such as screwing or engagement. Are preferred for manufacturing and handling. When the base is screwed and fixed to the head part, it is easier to work if a tool fitting part that can be rotated by a tool such as a spanner or a wrench is provided on the outer periphery of the base. The tool fitting portion may be a hexagonal nut-shaped member or one having other polygonal shapes or concave-convex shapes, similar to a normal metal fitting. As the tool fitting portion, a groove or unevenness in the diameter direction may be formed on the tip surface of the die.

【0012】 口金には、管状のバルブ金具を挿入できる装着孔を備えている。装着孔の奥に は、前記した作動弁機構が配置される。この装着孔の内径を、バルブ金具の雄ね じ外径よりも大きく設定しておくとともに、装着孔の内周には凹凸溝を形成して おく。すなわち、凹凸溝の凸部先端の最内周径が、バルブ金具の雄ねじ外径より も大きくなるようにしておく。したがって、口金の装着孔をバルブ金具に被せた ときには、装着孔の内周とバルブ金具の雄ねじ外径との間には若干の隙間があく ことになる。この隙間の量が大きい程、口金の装着孔をバルブ金具に被せて装着 する操作は行い易くなるが、後述する空気充填器を傾ける角度を大きくする必要 があったり、空気充填器とバルブ金具の固定が解除され易くなる。そこで、前記 隙間の量は、バルブ金具の雄ねじの外径やピッチによっても異なるが、通常、0 .数mmから数mm程度の範囲で設定しておくのが好ましい。The base has a mounting hole into which a tubular valve fitting can be inserted. The above-mentioned actuation valve mechanism is arranged behind the mounting hole. The inner diameter of the mounting hole is set larger than the outer diameter of the male fitting of the valve fitting, and a groove is formed on the inner circumference of the mounting hole. That is, the innermost peripheral diameter of the tip of the convex portion of the concave-convex groove is set to be larger than the outer diameter of the male screw of the valve fitting. Therefore, when the fitting hole of the mouthpiece is covered with the valve fitting, there is a slight gap between the inner circumference of the fitting hole and the outer diameter of the male thread of the valve fitting. The larger this gap is, the easier it will be to put the fitting on the valve fitting by covering it with the fitting hole, but it is necessary to increase the tilting angle of the air filler, which will be described later, or between the air filler and the valve fitting. It becomes easy to release the fixation. Therefore, although the amount of the gap varies depending on the outer diameter and pitch of the male screw of the valve fitting, it is usually 0. It is preferable to set in the range of several mm to several mm.

【0013】 凹凸溝の構造および配置は、バルブ金具の先端に口金の装着孔を被せ、バルブ 金具に対して口金を傾けたときに、凹凸溝がバルブ金具の雄ねじに噛み合うよう になっていればよい。通常、口金の装着孔とバルブ金具の雄ねじは、軸方向の両 端の2個所の一定範囲で噛み合うことになるので、凹凸溝を、少なくとも上記2 個所付近に設けておけばよい。凹凸溝として、挿入孔の所定長さ全体に螺旋状の 凹凸溝を形成しておけば、バルブ金具に対する空気充填器すなわち装着穴の挿入 深さや傾き方向に関わらず、確実に噛み合うようにすることができ、好ましい。 螺旋状の凹凸溝として、雌ねじを形成しておけば、通常の加工手段で能率的に形 成でき、加工が容易である。雌ねじの歯形やピッチは、任意に設定することがで きるが、バルブ金具の雄ねじとほぼ同じ程度に設定しておくと、噛み合いが良好 に行える。As for the structure and arrangement of the concave and convex grooves, if the tip of the valve fitting is covered with a fitting hole for the fitting and the fitting is tilted with respect to the valve fitting, the concave and convex grooves engage with the male screw of the valve fitting. Good. Normally, the fitting hole of the mouthpiece and the male screw of the valve fitting are engaged with each other in a certain range of two positions at both ends in the axial direction, and therefore the concave and convex grooves may be provided at least in the vicinity of the above two positions. If the spiral groove is formed over the entire length of the insertion hole as the concave and convex groove, ensure that the air filling device, that is, the mounting hole with respect to the valve fitting, will engage with each other regardless of the insertion depth and the tilt direction. Is possible and preferable. If a female screw is formed as the spiral concave-convex groove, it can be efficiently formed by ordinary processing means, and the processing is easy. The tooth profile and pitch of the internal thread can be set arbitrarily, but if they are set to about the same level as the external thread of the valve fitting, good meshing can be achieved.

【0014】 口金は、鋼やステンレス、真鍮など、通常の金具と同様の材料で形成しておく ことが出来るが、前記した凹凸溝の磨耗や変形を防ぐために、焼き入れ鋼などの 硬質材料を用いるのが好ましい。The mouthpiece can be made of the same material as ordinary metal fittings, such as steel, stainless steel, or brass, but hard material such as hardened steel is used to prevent wear and deformation of the uneven groove described above. It is preferably used.

【0015】[0015]

【作用】[Action]

空気充填器に設けられた口金の装着孔を、バルブ金具の中心軸方向から直線的 に被せて嵌め込むようにすると、バルブ金具の雄ねじの外径よりも装着孔の内径 のほうが大きいので、装着孔をスムーズにバルブ金具の奥まで嵌め込むことがで きる。装着孔の内部に設けられた作動弁機構とバルブ金具の作動弁機構が互いに 押し動かすことになるので、空気充填器からバルブ金具へと圧力空気が流れる状 態になる。 If the fitting hole of the mouthpiece provided on the air inflator is fitted so as to cover it straight from the center axis direction of the valve fitting, the inner diameter of the fitting hole is larger than the outer diameter of the male thread of the valve fitting. The hole can be inserted smoothly into the valve fitting. Since the actuating valve mechanism provided inside the mounting hole and the actuating valve mechanism of the valve fitting push each other, pressure air flows from the air filling device to the valve fitting.

【0016】 この状態で、空気充填器の装着孔をバルブ金具に対して傾けると、装着孔の内 周に設けられた凹凸溝が、バルブ金具の雄ねじと噛み合うことになる。凹凸溝が 雄ねじと噛み合った状態になれば、空気充填器をバルブ金具に押し付けるのを止 めて、空気充填器から手を離してもよい。これは、凹凸溝が雄ねじと噛み合った 状態では、バルブ金具に対して装着孔が軸方向に移動することができず、装着孔 すなわち空気充填器がバルブ金具から外れなくなるのである。前記した作動弁機 構の押し合いに伴う反発力あるいは圧力空気の作用によって、装着孔をバルブ金 具の軸方向に動かそうとする作用力がはたらくが、これらの作用力が、凹凸溝と 雄ねじを互いに強く押しつける方向に作用するので、凹凸溝と雄ねじの噛み合い が余計に強くなり、空気充填器がバルブ金具から外れ難くなる。In this state, when the mounting hole of the air filling device is tilted with respect to the valve fitting, the concave and convex groove provided on the inner periphery of the mounting hole meshes with the male screw of the valve fitting. When the concave-convex groove engages with the male screw, you may stop pressing the air filler against the valve fitting and let go of the air filler. This is because the mounting hole cannot move in the axial direction with respect to the valve fitting when the concave and convex groove is engaged with the male screw, and the mounting hole, that is, the air filler cannot be removed from the valve fitting. Due to the repulsive force or the action of pressurized air that accompanies the operation of the actuating valve mechanism described above, the acting force that tries to move the mounting hole in the axial direction of the valve metal works, but these acting forces act as the uneven groove and the male screw. Since they act in the direction of pressing each other strongly, the engagement between the concave and convex groove and the male screw becomes excessively strong, which makes it difficult for the air filler to come off from the valve fitting.

【0017】 したがって、この考案では、空気充填器の装着孔をバルブ金具の中心軸方向か ら直線的に嵌め込んだ後に、少し傾けるという操作を行うだけで、空気充填器を バルブ金具に装着固定することができるのである。 バルブ金具を取り付けた空気チューブに充分な量の圧力空気が充填された後は 、空気充填器すなわち装着孔の傾きを元に戻して、装着孔をバルブ金具の雄ねじ と同心上に位置させれば、装着孔の凹凸溝とバルブ金具の雄ねじとの係合状態は 解除されるので、このままの状態で、装着孔をバルブ金具の中心方向に直線的に 抜き取れば、空気充填器をバルブ金具から取り外すことができる。Therefore, in this invention, the air filling device is fixedly attached to the valve fitting by simply inserting the mounting hole of the air filling device from the central axis direction of the valve fitting and then slightly tilting it. You can do it. After the air tube to which the valve fitting is attached is filled with a sufficient amount of pressurized air, return the air filler, that is, the inclination of the mounting hole, and position the mounting hole concentric with the male thread of the valve fitting. , The engagement between the concave-convex groove of the mounting hole and the male screw of the valve fitting will be released.In this state, if you pull out the mounting hole linearly toward the center of the valve fitting, you can remove the air filler from the valve fitting. It can be removed.

When the mouthpiece 30 on the rear end side of the head portion 20 is attached to the valve fitting 40 (represented by the chain double-dashed line), the mouthpiece 30 is hooked on the valve fitting 40 and the operating portion 14 is pulled back. By properly using the two bases 30 as described above, the air filling device can be always used in an appropriate state depending on the structure of the tire or the air tube or the mounting state of the valve fitting 40. The operation portion 14 is provided with an enlarged non-slip portion at both the front end and the rear end so that the above two operations can be easily performed.

【0020】 図2は、ヘッド部20およびバルブ金具40の詳細構造を示している。まず、 バルブ金具40は、管状をなし、先端の外周に雄ねじ42が切られているととも に、内部には、先端に作動ピン44を備えた作動弁機構、いわゆるバルブコアを 備えている。この作動ピン44を引っ込めるように作動させると、弁が開いて、 圧力空気が流入できるようになる。作動ピン44は、バネあるいは空気の圧力で 、常に、突出する方向に付勢されているので、作動ピン44を強制的に引っ込め るように作動させない限り、バルブ金具40から圧力空気が漏れることはない。FIG. 2 shows a detailed structure of the head portion 20 and the valve fitting 40. First, the valve fitting 40 has a tubular shape and has a male screw 42 on the outer periphery of the tip end thereof, and further has an actuating valve mechanism having an actuating pin 44 at the tip end, a so-called valve core, inside thereof. When the actuating pin 44 is actuated to retract, the valve opens, allowing pressurized air to enter. Since the actuating pin 44 is always urged by the spring or air pressure in the protruding direction, pressurized air cannot leak from the valve fitting 40 unless the actuating pin 44 is forcibly retracted. Absent.

【0021】 ヘッド部20の内部には、エア通路24につながる空洞22が設けられている 。空洞22の端部に、中空円盤状のゴムパッキン28を介して、同じく中空円盤 状の口金30が取り付けられている。口金30は、焼き入れ鋼からなり、後端を ヘッド20にねじ込み取り付けされる。口金30の外周には、図1に示すように 、六角形状の工具嵌合部32が形成されていて、この工具嵌合部32をスパナ等 で回して、口金30をヘッド部20に着脱できるようになっている。A cavity 22 connected to the air passage 24 is provided inside the head portion 20. A hollow disk-shaped base 30 is attached to the end of the cavity 22 via a rubber disk 28 having a hollow disk shape. The base 30 is made of hardened steel and has a rear end screwed onto the head 20. As shown in FIG. 1, a hexagonal tool fitting portion 32 is formed on the outer periphery of the base 30, and the base 30 can be attached to and detached from the head portion 20 by turning the tool fitting 32 with a spanner or the like. It is like this.

【0022】 口金30の内周には、装着孔33が貫通形成されており、この装着孔33に雌 ねじ34が切られている。装着孔33すなわち雌ねじ34の内径D1 は、前記し たバルブ金具40の雄ねじ42の外径D0 よりも少し大きく設定されている。具 体的には、バルブ金具40の雄ねじ42は、各種の規格で寸法が決められている ので、例えば、バルブ金具40の雄ねじ42が、5/16−32山でピッチ径7 .8mmφに形成されている場合、口金30の雌ねじ34は、雄ねじ42と同じピ ッチおよび山数で、ピッチ径を8.8mmφに設定すればよい。また、雌ねじ34 のピッチ径は、7.8〜15.0mmφまで程度の範囲であれば使用できる。なお 、この考案で用いる口金30は、従来の通常の空気充填器で使用されていた口金 と、外観的には変わりがないので、これを区別するために、口金30の外面に特 定の着色を施しておいたり、特定の表面処理を施しておけば、販売あるいは流通 管理上、従来製品との違いを明確にしたり強調したりできる。A mounting hole 33 is formed through the inner periphery of the base 30, and a female screw 34 is cut in the mounting hole 33. The inner diameter D 1 of the mounting hole 33, that is, the female screw 34 is set to be slightly larger than the outer diameter D 0 of the male screw 42 of the valve fitting 40 described above. Specifically, since the male screw 42 of the valve fitting 40 is sized according to various standards, for example, the male screw 42 of the valve fitting 40 has 5 / 16-32 threads and a pitch diameter of 7. When it is formed with 8 mmφ, the female screw 34 of the mouthpiece 30 has the same pitch and the same number of threads as the male screw 42, and the pitch diameter may be set to 8.8 mmφ. Further, the pitch diameter of the female screw 34 can be used within a range of about 7.8 to 15.0 mmφ. Since the base 30 used in the present invention is similar in appearance to the base used in a conventional normal air filling device, in order to distinguish it, a special coloring is applied to the outer surface of the base 30. By applying a specific surface treatment, it is possible to clarify or emphasize the difference from conventional products in sales or distribution management.

【0023】 ヘッド部20の内部で、口金30の奥には、作動弁体60が配置されている。 作動弁体60は、円盤状をなす弁座部66と、弁座部66から前方に突出した板 片状の押動突起62を備えている。押動突起62は、先端から少し奥側で段差が つけられ奥側の幅が広くなっており、段差部分が傾斜部64となっている。弁座 部66の後方にはコイルバネ26が装着されている。コイルバネ26は、ヘッド 部20の前後の口金30、30に設けられた作動弁体60、60の間に挟まれた 状態で取り付けられており、両側の作動弁体60、60をそれぞれの口金30、 30の先端側へと突出させる方向に常に付勢している。Inside the head portion 20, an operating valve body 60 is arranged behind the mouthpiece 30. The actuating valve body 60 includes a disc-shaped valve seat portion 66 and a plate-shaped pushing protrusion 62 protruding forward from the valve seat portion 66. The pushing protrusion 62 has a step slightly deeper from the tip end to have a wider width on the back side, and the step portion is an inclined portion 64. The coil spring 26 is mounted behind the valve seat portion 66. The coil spring 26 is attached in a state of being sandwiched between the operation valve bodies 60, 60 provided on the mouthpieces 30, 30 in front of and behind the head portion 20, and the operation valve bodies 60, 60 on both sides are attached to the respective mouthpieces 30. , 30 is always urged in the direction of projecting to the tip side.

【0024】 作動弁体60は、上記コイルバネ26の反発力と空洞22内に供給された圧力 空気の圧力によって、弁座部66がゴムパッキン28に強く押し付けられており 、この状態では、圧力空気が噴出することは出来ない。コイルバネ26が無くて も、圧力空気の作用で、作動弁体60を弾力的に付勢しておくことは出来るが、 コイルバネ26を取り付けておいたほうが、作動便体60の作動が迅速かつ確実 に行える。In the actuating valve body 60, the valve seat portion 66 is strongly pressed against the rubber packing 28 by the repulsive force of the coil spring 26 and the pressure of the pressure air supplied into the cavity 22. Can not squirt. Even if the coil spring 26 is not provided, the actuating valve body 60 can be elastically biased by the action of pressure air, but the actuation of the actuating body 60 is quick and reliable when the coil spring 26 is attached. You can do it.

【0025】 上記のような構造を備えた空気充填器10を使用するには、例えば、図1に示 すように、空気充填器10のヘッド部20先端の口金30に形成された装着孔3 3を、バルブ金具40の先端に中心軸方向から直線的に嵌め込む。 図3に示すように、装着孔33の内部にバルブ金具40の先端が入るが、この ときには、口金30の雌ねじ34とバルブ金具40の雄ねじ42の間には隙間が あいている。バルブ金具40の作動ピン44と装着孔33の奥にある押動突起6 2の先端面が当たると、互いに反対方向に引っ込むように作動する。また、バル ブ金具40の端面が押動突起62の傾斜部64に当たることによっても、互いに 押動し合うことになる。その結果、空気充填器20のヘッド部20では、作動弁 体60の弁座部66とゴムパッキン28の間に隙間があくので、ここを通り、さ らに、押動突起62とゴムパッキン28の間を通って、圧力空気が口金30の先 端側へと噴出する。作動弁体60の移動に伴って、コイルバネ26が縮められる ので、作動弁体60にはコイルバネ26の反発力が強く作用する。バルブ金具4 0では、作動ピン44が引っ込むことによって、弁が開くので、口金30からバ ルブ金具40のほうへと圧力空気が流入することになる。To use the air filling device 10 having the above-described structure, for example, as shown in FIG. 1, the mounting hole 3 formed in the mouthpiece 30 at the tip of the head portion 20 of the air filling device 10. 3 is linearly fitted to the tip of the valve fitting 40 from the central axis direction. As shown in FIG. 3, the tip of the valve fitting 40 enters the inside of the mounting hole 33. At this time, there is a gap between the female screw 34 of the base 30 and the male screw 42 of the valve fitting 40. When the actuating pin 44 of the valve fitting 40 and the tip end surface of the pushing protrusion 62 at the back of the mounting hole 33 come into contact with each other, they act so as to retract in opposite directions. Further, the end faces of the valve fittings 40 hit the inclined portions 64 of the pushing protrusions 62, so that the pushing members 62 push each other. As a result, in the head portion 20 of the air filling device 20, there is a gap between the valve seat portion 66 of the actuating valve body 60 and the rubber packing 28. The compressed air is ejected toward the front end side of the base 30 through the gap. Since the coil spring 26 is contracted along with the movement of the actuation valve body 60, the repulsive force of the coil spring 26 strongly acts on the actuation valve body 60. In the valve fitting 40, the valve is opened by retracting the actuating pin 44, so that pressurized air flows from the base 30 toward the valve fitting 40.

【0026】 但し、この状態では、前記したコイルバネ26の反発力や圧力空気の作用で、 ヘッド部20とバルブ金具40を離す方向の力が加わっているので、ヘッド部2 0をバルブ金具40に押しつけていないと、ヘッド部20がバルブ金具40から 外れてしまう。 そこで、図4に示すように、バルブ金具40の中心軸に対して、ヘッド部20 を少し傾ける。傾ける方向は任意の方向で良い。そうすると、口金30の装着孔 33および雌ねじ34も、バルブ金具40の雄ねじ42に対して傾くことになり 、口金30の雌ねじ34が、バルブ金具40の雄ねじ42に接触して互いに噛み 合うことになる。図に示すように、雌ねじ34と雄ねじ42が噛み合うのは、装 着孔33の入口内周縁近い部分X1 と、このX1 部分と対称位置になる、装着孔 33の奥でバルブ金具40の先端縁近い部分X2 である。それぞれの噛み合い部 分X1 およびX2 では、ねじ山の1個分もしくは数個分が一定の角度範囲で互い に噛み合うことになる。However, in this state, the repulsive force of the coil spring 26 and the action of the pressurized air exert a force in the direction of separating the head portion 20 and the valve fitting 40, so that the head portion 20 is attached to the valve fitting 40. If not pressed, the head portion 20 will come off the valve fitting 40. Therefore, as shown in FIG. 4, the head portion 20 is slightly tilted with respect to the central axis of the valve fitting 40. The tilting direction may be any direction. Then, the mounting hole 33 and the female screw 34 of the base 30 are also inclined with respect to the male screw 42 of the valve fitting 40, and the female screw 34 of the base 30 comes into contact with the male screw 42 of the valve fitting 40 and meshes with each other. .. As shown, the internal thread 34 and external thread 42 engages has an inlet in the peripheral portion close to X 1 of the instrumentation Chakuana 33, becomes the X 1 moiety and symmetrical position of the valve fitting 40 at the back of the mounting hole 33 It is a portion X 2 near the tip edge. At each meshing portion X 1 and X 2 , one or several screw threads mesh with each other within a certain angle range.

【0027】 この状態でも、前記したように、作動ピン44や作動弁体60が元に戻ろうと する復元力や圧力空気の作用で、口金30をバルブ金具40から離す方向に力が 加わっている。この力が、雌ねじ34と雄ねじ42を噛み合い部分X1 、X2 で 強く押しつけ合うことになり、この雌ねじ34と雄ねじ42が互いに噛み合って いる限り、それ以上は互いに移動することが出来ず、バルブ金具40と口金30 すなわちヘッド部20が一時的に固定された状態になる。Even in this state, as described above, due to the restoring force of the actuating pin 44 and the actuating valve body 60 to return to the original state and the action of the pressurized air, a force is applied in the direction of separating the base 30 from the valve fitting 40. .. This force causes the female screw 34 and the male screw 42 to be strongly pressed against each other at the meshing portions X 1 and X 2 , and as long as the female screw 34 and the male screw 42 are meshed with each other, they cannot move any more and the valve The metal fitting 40 and the base 30, that is, the head portion 20 is temporarily fixed.

【0028】 上記作用からも判るように、口金30の雌ねじ34とバルブ金具40の雄ねじ 42は、円周上の何れ方向および軸方向の何れの場所でも、確実に噛み合うこと ができるので、空気充填器10を傾ける方向や傾き角度を正確に設定する必要は なく、極めて簡単に操作することができる。 その後は、ヘッド部20をバルブ金具40に押し付けていなくても、前記した 雌ねじ34と雄ねじ42の噛み合いによって一時的に固定された状態になり、圧 力空気は、空気充填器のヘッド部20からバルブ金具40へと確実に供給される 。空気充填器10の操作部14から手を離しても、前記噛み合いが充分であれば 、ヘッド部20の傾きを変えるような力を加えない限り、空気充填器10がバル ブ金具40から外れる心配はない。なお、空気充填器10の自重によるモーメン トが、ヘッド部20をバルブ金具40に対して、より傾ける方向に加わるように しておけば、空気充填器10がバルブ金具40から外れ難い。具体的には、図1 では、下向きに重力が加わっているとすると、空気充填器10を下向きに傾けて バルブ金具40に固定するようにしたほうがよい(図の白矢印と反対方向になる )。空気充填器10に適当な工具等からなる重しを乗せておいたり、空気充填器 10の端部やホース50を適当な手段で仮固定しておけば、誤って空気充填器1 0の傾きを変えたりして、バルブ金具40から外れてしまうことを確実に防げる 。As can be seen from the above operation, the female screw 34 of the mouthpiece 30 and the male screw 42 of the valve fitting 40 can surely mesh with each other at any position on the circumference in any direction and in the axial direction. It is not necessary to accurately set the tilting direction and tilting angle of the device 10, and the device can be operated very easily. After that, even if the head section 20 is not pressed against the valve fitting 40, the head section 20 is temporarily fixed by the engagement of the female thread 34 and the male thread 42 described above, and the compressed air flows from the head section 20 of the air filling device. It is reliably supplied to the valve fitting 40. Even if the operator releases the operating portion 14 of the air filling device 10, if the engagement is sufficient, the air filling device 10 may be disengaged from the valve fitting 40 unless a force that changes the inclination of the head portion 20 is applied. There is no. It should be noted that if the moment due to the weight of the air filling device 10 is applied in the direction in which the head portion 20 is more inclined with respect to the valve fitting 40, the air filling device 10 is unlikely to come off the valve fitting 40. Specifically, in FIG. 1, if gravity is applied downward, it is better to tilt the air filler 10 downward and fix it to the valve fitting 40 (the direction opposite to the white arrow in the figure). .. If the weight made of a suitable tool is placed on the air filling device 10 or the end of the air filling device 10 and the hose 50 are temporarily fixed by an appropriate means, the inclination of the air filling device 10 is mistakenly tilted. You can surely prevent it from coming off the valve fitting 40 by changing.

【0029】 バルブ金具40から目的の空気チューブに圧力空気が充填されれば、空気充填 器10をバルブ金具40から取り外す。具体的には、空気充填器10のヘッド部 20の傾きを、バルブ金具40の中心軸方向に一致するように元に戻す。そうす ると、雌ねじ34と雄ねじ42の噛み合いが解除されて、前記図3の状態になる 。この状態では、前記したコイルバネ26の反発力や圧力空気の作用で、バルブ 金具40からヘッド部20を離す方向に力が作用するので、特別な操作を行わな くても、空気充填器10は自然にバルブ金具40から外れることになる。バルブ 金具40から空気充填器10が外れれば、バルブ金具40の作動ピン44が元に 戻って弁が閉まるので、バルブ金具40から圧力空気が漏れることはない。また 、空気充填器10でも、作動弁体60が元に戻って弁が閉まるので、圧力空気が 無駄に噴出する心配はない。When the target air tube is filled with the pressure air from the valve fitting 40, the air filling device 10 is removed from the valve fitting 40. Specifically, the inclination of the head portion 20 of the air filling device 10 is returned to the original position so as to coincide with the central axis direction of the valve fitting 40. Then, the engagement between the female screw 34 and the male screw 42 is released, and the state shown in FIG. 3 is obtained. In this state, due to the repulsive force of the coil spring 26 and the action of the pressurized air, a force acts in the direction of separating the head portion 20 from the valve fitting 40, so that the air filling device 10 can operate without any special operation. It will come off from the valve fitting 40 naturally. When the air filler 10 is detached from the valve fitting 40, the operating pin 44 of the valve fitting 40 returns to its original position and the valve is closed, so that pressurized air does not leak from the valve fitting 40. Further, in the air filling device 10 as well, since the actuating valve body 60 returns to its original state and the valve is closed, there is no concern that the pressurized air will be unnecessarily ejected.

【考案の効果】[Effect of the device]

以上に述べた、この考案にかかる空気充填器によれば、ヘッド部の口金に形成 された装着孔に雌ねじなどの凹凸溝を形成しておくだけで、空気充填器を簡単か つ確実にバルブ金具に装着固定することができる。 すなわち、この考案では、口金の装着孔をバルブ金具の先端に直線的に嵌め込 んだ後、装着孔すなわち口金およびヘッド部を傾けるという、極めて簡単な操作 を行うだけで、バルブ金具の雄ねじと口金の凹凸溝が噛み合って、バルブ金具に 空気充填器のヘッド部を固定しておくことができるのである。 According to the air filling device of the present invention described above, the air filling device can be easily and surely secured by simply forming the uneven groove such as the female screw in the mounting hole formed in the mouthpiece of the head portion. Can be attached and fixed to metal fittings. In other words, according to this invention, the male thread of the valve fitting can be connected to the male thread of the valve fitting by simply inserting the fitting hole of the fitting into the tip of the valve fitting and then tilting the fitting hole, that is, the fitting and the head. The concavo-convex groove of the base meshes with each other, and the head part of the air filler can be fixed to the valve fitting.

【0031】 その結果、従来のように、空気充填作業中、常に空気充填器をバルブ金具に押 しつけておくような面倒はなく、空気充填器をバルブ金具に固定した後は、作業 者が手を離して放っておいてよいことになり、労力を大幅に削減できる。また、 従来のクリップ状の係合機構のように、作業者がいちいちヘッド部の先端まで手 を延ばして係合および係合解除の操作を行う必要はなく、作業者はヘッド部から 離れた操作部を持って空気充填器を傾けたり元に戻したりするだけで、空気充填 器の装着および取り外しが出来るのであり、この点でも、作業の簡略化あるいは 労力の低減を図ることができる。しかも、クリップ状の係合機構のように、バル ブ金具のねじ山を潰したり、バルブ金具を変形させる心配もなく、故障したり磨 耗することもないので、安定した動作を長期間にわたって良好に発揮することが 可能になる。As a result, unlike the conventional case, there is no trouble of constantly pressing the air filling device against the valve fitting during the air filling work, and after fixing the air filling device to the valve fitting, the operator manually You can leave them apart and save a lot of effort. Further, unlike the conventional clip-shaped engaging mechanism, it is not necessary for the operator to extend the hand to the tip of the head portion to perform the engagement and disengagement operations. The air filler can be attached and detached simply by tilting or returning the air filler by holding the part, and in this respect as well, the work can be simplified or the labor can be reduced. Moreover, unlike the clip-shaped engagement mechanism, there is no risk of crushing the thread of the valve fitting or deforming the valve fitting, and there is no failure or wear, so stable operation is good over a long period of time. It will be possible to demonstrate to.
