[Movable body 150 and driving body 160]
The movable body 150 and the driving body 160 will be described in detail with reference to FIGS. 3A, 3B, 3C, 3D, 4A, 4B, 4C, 4D, and 5. 3A is a perspective view of the movable body 150 seen obliquely from above, FIG. 3B is a perspective view of the movable body 150 seen obliquely from below, FIG. 3C is a plan view of the movable body 150, and FIG. A front view of body 150 is shown. 4A is a perspective view of the driving body 160 seen from diagonally above, FIG. 4B is a perspective view of the driving body 160 seen from diagonally below, FIG. 4C is a bottom view of the driving body 160, and FIG. Shows a front view of the driving body 160. Further, FIG. 5 is a front view showing a state where the movable body 150 and the driving body 160 are engaged with each other.
駆動体１６０は基材１４０に固定して設置される、中央に挿通孔を設けた円盤状の部材であり、筒状体の下端部には、挿通孔の周囲に、下方すなわち操作体１１０を押し込む方向に向けて円周方向に傘状歯１６１が形成されている。傘状歯１６１は、複数（図では八つ）の山状の突起が周方向に並べて配置されることにより形成され、それにより山状の凸部と谷状の凹部が円周方向に繰り返し配列される。また、駆動体１６０の中央に設けられた挿通孔には、最終ギヤ１３４の下方軸部材１３４Ｂが挿通される。 The driving body 160 is a disk-shaped member that is fixedly installed on the base material 140 and has an insertion hole in the center. The lower end portion of the cylindrical body is provided with a lower portion, that is, the operation body 110, around the insertion hole. Umbrella teeth 161 are formed in the circumferential direction toward the pushing direction. The beveled tooth 161 is formed by arranging a plurality (eight in the figure) of mountain-shaped projections side by side in the circumferential direction, whereby mountain-shaped convex portions and valley-shaped concave portions are repeatedly arranged in the circumferential direction. To be done. Further, the lower shaft member 134B of the final gear 134 is inserted into an insertion hole provided in the center of the driving body 160.
また、本実施形態においては、駆動体１６０を構成する円盤状の部材に、基材１４０に固定するためのネジを挿通するネジ穴が複数設けられている。 Further, in the present embodiment, the disk-shaped member forming the driving body 160 is provided with a plurality of screw holes through which screws for fixing to the base material 140 are inserted.
可動体１５０は操作体１１０の回動軸と同軸上に回転可能に配置される、中央に挿通孔が設けられた筒状の部材であり、筒状体の上端部には上方すなわち操作体１１０を押し込む方向とは逆方向に向けて傘状の摺動歯１５１が回転軸周りに円周方向に形成されている。摺動歯１５１は、傘状歯１６１と同様に、複数（図では八つ）の山状の突起が周方向に並べて配置されることにより、山状の凸部と谷状の凹部とが繰り返すよう形成されており、傘状歯１６１と摺動歯１５１は互いに係合して摺動可能に接するよう構成される。すなわち、図５に示すように、傘状歯１６１の山状の凸部と摺動歯１５１の谷状の凹部とが係合し、傘状歯１６１の谷状の凹部と摺動歯１５１の山状の凸部が係合するように構成される。 The movable body 150 is a tubular member rotatably arranged coaxially with the rotation axis of the operating body 110 and having an insertion hole in the center thereof. Umbrella-shaped sliding teeth 151 are formed in the circumferential direction around the rotation axis in the direction opposite to the direction in which is pushed. Similar to the umbrella tooth 161, the sliding tooth 151 has a plurality of (eight in the figure) mountain-shaped projections arranged side by side in the circumferential direction, so that a mountain-shaped convex portion and a valley-shaped concave portion are repeated. Are formed so that the beveled tooth 161 and the sliding tooth 151 are configured to engage with each other and slidably contact each other. That is, as shown in FIG. 5, the mountain-shaped projections of the beveled teeth 161 and the valley-shaped recesses of the sliding teeth 151 are engaged with each other, and the valley-shaped recesses of the umbrella-shaped teeth 161 and the sliding teeth 151 are engaged. It is configured so that the mountain-shaped protrusions are engaged.
また、可動体１５０の中央に設けられた挿通孔は、最終ギヤ１３４の下方軸部材１３４Ｂと一体となって回転できるよう、一部に平坦面を設けている。すなわち、最終ギヤ１３４の下方軸部材１３４Ｂは円柱の一部を切り欠き平坦面を設けているが、可動体１５０の挿通孔も単なる円形ではなく、下方軸部材１３４Ｂの平坦面に対応する平坦面を設けている。このようにすることで、最終ギヤ１３４の回転に追従して可動体１５０が回転するように構成することができる。 Further, the insertion hole provided at the center of the movable body 150 is partially provided with a flat surface so that the insertion hole can rotate integrally with the lower shaft member 134B of the final gear 134. That is, the lower shaft member 134B of the final gear 134 is provided with a flat surface by notching a part of the cylinder, but the insertion hole of the movable body 150 is not a mere circle, but a flat surface corresponding to the flat surface of the lower shaft member 134B. Is provided. By doing so, the movable body 150 can be configured to rotate following the rotation of the final gear 134.
また、可動体１５０の挿通孔の内面に沿うようにバネ部材１５２が設けられている。バネ部材１５２により、可動体１５０には常に上向きの力、つまり、駆動体１６０の傘状歯１６１に対して可動体１５０の摺動歯１５１が押し付けられる方向に力が印加される。 A spring member 152 is provided along the inner surface of the insertion hole of the movable body 150. The spring member 152 always applies an upward force to the movable body 150, that is, a force in a direction in which the sliding teeth 151 of the movable body 150 are pressed against the beveled teeth 161 of the driving body 160.
さらに、可動体１５０の下部は、複数のネジによって操作体１１０に固定されている。そのため、可動体１５０と操作体１１０は、周方向及び軸方向ともに、一体となって動作する。 Further, the lower portion of the movable body 150 is fixed to the operating body 110 with a plurality of screws. Therefore, the movable body 150 and the operating body 110 operate integrally in both the circumferential direction and the axial direction.
〔可動体１５０及び操作体１１０の動作〕
次に、最終ギヤ１３４の回転に連動した可動体１５０及び操作体１１０の動作について、最終ギヤ１３４、可動体１５０及び駆動体１６０が組み合わされた状態を斜め下方から見た斜視図である図６を用いて説明する。
[Operation of the movable body 150 and the operating body 110]
6 is a perspective view of the operation of the movable body 150 and the operating body 110 interlocked with the rotation of the final gear 134 when the final gear 134, the movable body 150, and the driving body 160 are combined and viewed from diagonally below. Will be explained.
モータ１２０の動作に伴い最終ギヤ１３４が開閉弁を閉じる方向に回転すると、可動体１５０の挿通孔と最終ギヤ１３４の下方軸部材１３４Ｂとが係合しているため、可動体１５０は最終ギヤ１３４とともに回転する。一方、駆動体１６０は基材１４０に固定されているため、駆動体１６０は動かず、実質的に不動である。したがって、可動体１５０は駆動体１６０に対して回転するため、可動体１５０の摺動歯１５１が傘状歯１６１に対して摺動することにより、摺動歯１５１の山状の凸部が傘状歯１６１の山状の凸部に押され、バネ部材１５２の上向きの力に抗して、下方に押し下げられることになる。つまり、可動体１５０は下方に押し下げられながら回転することになる。なお、回転に伴い可動体１５０が押し下げられる量は、最大で傘状歯１６１の山状の凸部の高さの分になるが、それによってガス栓３００を回動軸方向に移動させるのに十分な量が設定される。 When the final gear 134 rotates in the direction of closing the on-off valve with the operation of the motor 120, the insertion hole of the movable body 150 and the lower shaft member 134B of the final gear 134 are engaged, so that the movable body 150 has the final gear 134. Rotate with. On the other hand, since the driving body 160 is fixed to the base material 140, the driving body 160 does not move and is substantially immobile. Therefore, since the movable body 150 rotates with respect to the driving body 160, the sliding teeth 151 of the movable body 150 slide with respect to the beveled teeth 161, so that the mountain-shaped convex portions of the sliding teeth 151 move to the umbrella. It is pushed by the mountain-shaped convex portion of the tooth 161 and is pushed down against the upward force of the spring member 152. That is, the movable body 150 rotates while being pushed down. In addition, the amount by which the movable body 150 is pushed down by the rotation is the maximum of the height of the mountain-shaped convex portion of the beveled tooth 161. Therefore, it is necessary to move the gas plug 300 in the rotation axis direction. Sufficient amount is set.
ところで、本実施形態において、可動体１５０は複数のネジにより操作体１１０に固定されている。そのため、操作体１１０は軸方向及び周方向に関して可動体１５０の動作に追従するように動作する。すなわち、可動体１５０の押し下げられながら回転する動作に伴い、操作体１１０も押し下げられながら回転する動作を行う。 By the way, in the present embodiment, the movable body 150 is fixed to the operating body 110 by a plurality of screws. Therefore, the operating body 110 operates so as to follow the operation of the movable body 150 in the axial direction and the circumferential direction. That is, as the movable body 150 rotates while being pushed down, the operating body 110 also rotates while being pushed down.
そして、操作体１１０には、ガス栓３００のつまみ部３１０に係合する凹部１１１が形成されているため、操作体１１０の押し下げられながら回転するという動作に伴い、ガス栓３００を下方に押し下げながら回転させることができる。その結果、ガス栓３００の動作に連動したガス管２００の開閉弁を閉弁することができる。 Since the operation body 110 is formed with the concave portion 111 that engages with the knob portion 310 of the gas stopper 300, the gas stopper 300 is pushed downward while the operation body 110 is rotated while being pushed down. It can be rotated. As a result, the opening / closing valve of the gas pipe 200 that is linked to the operation of the gas plug 300 can be closed.
このようにして、一つのモータ１２０を駆動するだけで、操作体１１０を押し下げながら回転させることができ、その結果、ガス栓３００に連動したガス管２００の開閉弁を閉弁することができる。 In this way, the operating body 110 can be rotated while being pushed down by driving only one motor 120, and as a result, the opening / closing valve of the gas pipe 200 linked with the gas plug 300 can be closed.
〔緊急時の遠隔操作〕
次に、地震発生時など、緊急時におけるガス栓３００の遠隔操作について説明する。
[Remote control in an emergency]
Next, remote operation of the gas stopper 300 in an emergency such as when an earthquake occurs will be described.
本実施形態におけるガス栓駆動装置１００は、図示しない通信部及び制御部を備えており、地震や火災などの発生に伴い、ガス栓３００を閉めるべき信号を受信すると、制御部がモータ１２０を閉方向に回転させる信号を発生する。モータ１２０は制御部からの信号にしたがい、ガス栓３００を閉方向に回転させるようモータ１２０の回転軸を動作する。そして、モータ１２０の回転軸の回転に伴い、上述の通り、操作体１１０が押し下げられながら回転し、それによってガス栓３００を下方に押し下げながら回転させることができる。このようにして、災害時にも、人手によらず、遠隔操作によってガス栓３００を閉めることができガス漏れ等による被害を抑えることができる。 The gas plug drive device 100 according to the present embodiment includes a communication unit and a control unit (not shown), and when a signal to close the gas plug 300 is received due to occurrence of an earthquake or a fire, the control unit closes the motor 120. Generate a signal to rotate in the direction. The motor 120 operates the rotating shaft of the motor 120 to rotate the gas plug 300 in the closing direction according to a signal from the control unit. Then, as the rotation shaft of the motor 120 rotates, as described above, the operating body 110 rotates while being pushed down, whereby the gas plug 300 can be rotated while pushing down. In this way, even in the event of a disaster, the gas stopper 300 can be closed by remote operation without human intervention, and damage due to gas leakage or the like can be suppressed.
〔通常時の操作〕
次に、本実施形態におけるガス栓駆動装置１００を使用した状態で、人手によってガス栓３００の操作を行う場合について説明する。

Has been formed.
つまり、操作片１７０の中央に設けられた凹部は、最終ギヤ１３４の上方軸部材１３４Ｃと一体となって回転できるよう、一部に平坦面を設けている。すなわち、最終ギヤ１３４の上方軸部材１３４Ｃは円柱の一部を切り欠き平坦面を設けているが、操作片１７０の凹部も単なる円筒形ではなく、該平坦面に対応する平坦面を設けている。このようにすることで、操作片１７０の回転に追従して最終ギヤ１３４が回転するように構成することができる。 That is, the concave portion provided in the center of the operation piece 170 is partially provided with a flat surface so that the concave portion can rotate integrally with the upper shaft member 134C of the final gear 134. That is, the upper shaft member 134C of the final gear 134 is provided with a flat surface by cutting out a part of the cylinder, but the concave portion of the operation piece 170 is not a simple cylindrical shape, but is provided with a flat surface corresponding to the flat surface. . By doing so, the final gear 134 can be configured to rotate following the rotation of the operation piece 170.
上記のように構成されているため、通常時には、操作片１７０のつまみ部１７１をつまんで回転させることにより、最終ギヤ１３４を追従して回転させることができ、その結果、ガス栓３００を開閉動作させることが可能となる。 Since it is configured as described above, normally, by pinching and rotating the knob portion 171 of the operation piece 170, the final gear 134 can be tracked and rotated, and as a result, the gas stopper 300 is opened and closed. It becomes possible.
なお、本実施形態においては、凹部１１１を有する操作体１１０と可動体１５０を別体とし、両者をネジによって固定することで一体となって動作するように構成したが、操作体１１０と可動体１５０を一体とし、一つの要素としてもよい。すなわち、可動体１５０の下部に凹部１１１を設け、つまみ部３１０と係合させるものであってもよい。 In addition, in the present embodiment, the operating body 110 having the recess 111 and the movable body 150 are formed as separate bodies, and the two are fixed by screws so as to operate integrally. The 150 may be integrated into one element. That is, the concave portion 111 may be provided in the lower portion of the movable body 150 to be engaged with the knob portion 310.
