- the interior body 11 and the exterior body 12 are integrated.
- a rotary handle cap 10 is attached to the rotary handle 8 of the fluid controller 1.
- the operation of attaching the rotating handle cap 10 is simple. This is because the rotary handle cap 10 is arranged with respect to the rotary handle 8 so that the central axis of the rotary handle 8 and the central axis of the rotary handle cap 10 are substantially common. Then, the rotation handle cap 10 is caused to move straight along the central axis with respect to the rotation handle 8. In short, the rotary handle cap 10 is pushed so that the rotary handle 8 is housed inside the rotary handle cap 10.
- the outer peripheral surface of the rotary handle 8 is in contact with the inner peripheral surface of the interior body 11 as shown in FIGS. Further, the interior body side uneven portion 14 and the exterior body side uneven portion 23 are engaged with each other, and the rotary handle 8 is mounted in the interior body 11. Under this state, when the exterior body 12 is rotated about its central axis, the rotary handle 8 is also rotated. At this time, since the diameter of the exterior body 12 is larger than that of the rotary handle 8, the rotary handle 8 can be rotated with a small rotational force.

Even if the inner peripheral surface of the exterior body 12 and the outer peripheral surface of the interior body 11 are in contact with each other, the balls 27 roll on the outer periphery surface of the interior body 11, so that the exterior body 12 is pulled out of the interior body 11.
- the exterior body 12 can be moved straight without resistance.
- the ball 27 is fitted into the positioning recess 16.
- the feeling of impact when the ball 27 is fitted is transmitted to the finger operating the exterior body 12, so the operator further pulls the exterior body 12 out of the interior body 11. Stop operation. Even if the operator performs an operation of further pulling out the exterior body 12 from the interior body 11 in spite of a sense of impact, the ball 27 is fitted in the positioning recess 16. No more can be extracted from the body 11.
- the holding unit 30 is in an initial state in which the pin 31 is retracted from the interior body side uneven portion 14 and the exterior body side uneven portion 23 as shown in FIG.
- the operation piece 36 is pressed toward the exterior body 12 by pressing the operation piece 36 with a finger or the like.
- the pin 31 integrally connected to the pressed operation piece 36 moves forward.
- the interior body side uneven portion 14 and the exterior body side uneven portion 23 are separated with a gap, so that the pin 31 enters the gap.
- the fixing screw 35 is attached to the guide groove 34 which is a long hole in the pin 31, the pin 31 advances further by the head of the fixing screw 35 coming into contact with the inner wall of the guide groove 34. There is no.

As a result, the exterior body 12 cannot move to the interior body 11 along its central axis. In addition, since a part of the ball 27 is fitted in the positioning recess 16 provided on the outer surface of the interior body 11, the exterior body 12 can rotate with respect to the interior body 11.
- the exterior body 12 is rotatable with respect to the interior body 11, for example, even if a rotational force is applied to the exterior body 12 for some reason, the exterior body 12 rotates but the interior body 11 is Does not rotate.
- the rotary handle 8 may rotate when some rotational force or impact is applied to the rotary handle 8.
- the rotary handle cap 10 is attached to the rotary handle 8 even if any rotational force or impact is applied to the exterior body 12, the exterior body 12 only rotates at that time, and the interior body 11 and the rotation The handle 8 does not rotate. Therefore, for example, when the rotary handle 8 is in the open position, if the rotary handle cap 10 is attached to the rotary handle 8, even if some rotational force or impact is applied to the exterior body 12. The predetermined position of the rotary handle 8 does not change.

Abstract
Description
このようにして、ハンドルをハンドルカバー2の中に収容してしまうので、特許文献1に記載されたバルブハンドルカバーにおいては、「不特定多数の何人もこのバルブハンドルカバーが付いていればバルブの開閉が容易でなく、限られた管理者だけが操作」することができ、「手でバルブハンドルカバーを握っても、・・・力任せのバルブ操作ができない」といった技術的効果が奏される(以上、特許文献1の段落番号0007、0008、0011、及び0013、並びに図1及び図2参照)。
(1) 回転軸に装着されると共にその回転軸を回転させる回転ハンドルに装着される回転ハンドル用キャップであって、
前記回転ハンドルに固定されるように装着される内装体と、前記内装体を内装する外装体と、前記内装体に対して前記外装体の回転軸を中心にして前記外装体を回転可能及び回転不能にするクラッチ部と、前記クラッチ部により前記内装体に対して回転可能にされた前記外装体の回転可能状態を保持する保持部とを備えることを特徴とする回転ハンドル用キャップであり、
(2) 前記クラッチ部が、前記内装体の、前記外装体に向かう端縁部に形成された内装体側凹凸部と、前記外装体の、前記内装体に向かう面に形成され、かつ前記内装体側凹凸部と係合するように配置された外装体側凹凸部とを備えてなる前記(1)に記載の回転ハンドル用キャップであり、
(3) 前記保持部が、前記内装体側凹凸部と前記外装体側凹凸部とを係合するときには前記内装体側凹凸部と前記外装体側凹凸部とから退避し、前記内装体側凹凸部と前記外装体側凹凸部とを分離させるときには、前記内装体側凹凸部と前記外装体側凹凸部との間に介装される移動子である前記(2)に記載の回転ハンドル用キャップである。
なお、この内装体11を弾力性が小さくて剛性のある適宜の材料で形成する場合には、図示してはいないが、前記回転ハンドル8の外周面に、その中心軸線に平行に形成された係止用溝が形成されているときには、前記内装体11の内周面に前記係止用溝に嵌まり込むことのできる係止用キイを形成しておくことにより、剛性のある内装体11を回転すると前記回転ハンドル8を円滑に回転させることができる。また、このような係止用溝と係止用キイとの組み合わせに限らず、前記内装体11を回転させると前記回転ハンドル8を回転させることのできる機械的構成を適宜に採用することができる。また、換言すると、前記回転ハンドル8に対して内装体11をその中心軸線に沿って押し込むことにより円滑に内装体11の内部空間内に前記回転ハンドル8を挿入乃至嵌合することができ、しかも前記回転ハンドル8の回転によって前記内装体11が大きく変形しない限り、内装体11の材料を適宜に決定することができ、また、前記回転ハンドル8の回転と内装体11の回転とを同時に行うことのできる機械的結合構造を適宜に採用することができる。
この外装体側凹凸部23は、外装体12の中心軸線を中心とする半径線に一致する稜線と、この稜線と隣接する稜線との間に設けられた、前記外装体12の中心軸線を中心とする半径線に一致する谷線とで、山と谷とが交互に繰り返される凹凸24を、有する。この外装体側凹凸部23における前記凹凸24は、前記内装体11に形成された内装体側凹凸部14における前記凹凸15と噛み合うように形成される。
なお、この例においては、外装体12の円筒体部17を肉厚に形成しているので、前記ボール装着孔26は外装体12の周側面から内周面に貫通する孔に形成されているが、外装体12の円筒部17がボール27を装着するに十分な肉厚を有していないときには、図3~6に示されるように、ボール装着孔26を形成するための取付部材を適宜に装着することによりボール27及びその付勢部材を装着するに十分な大きさを確保することができる。
保持部を構成する一例である移動子は、前記ピンに限らずに、内装体用凹凸部と外装体用凹凸部との間に形成される間隙に位置することにより前記内装体用凹凸部と外装体用凹凸部とが係合状態になることを阻止することができ、また内装体用凹凸部及び外装体用凹凸部から退避することにより内装体用凹凸部と外装体用凹凸部とが係合する係合状態を実現することができる限り、様々の機械的構成を採用することができる。
