Description

本発明は、ガス流通路が内部に形成された筒状のガス栓本体に、閉じ位置と開き位置との間で前記ガス栓本体の軸方向に移動自在なスライド弁と、前記ガス流通路のガス流通方向で前記スライド弁よりも上流側に配置された過流出防止弁と、前記ガス流通方向で前記スライド弁と前記過流出防止弁との間に配置されて、前記閉じ位置と前記開き位置との間での前記スライド弁の移動により前記過流出防止弁をリセットさせるリセット操作を行うリセット手段とが備えられているガス栓に関する。   The present invention provides a cylindrical gas stopper body having a gas flow passage formed therein, a slide valve movable in the axial direction of the gas stopper body between a closed position and an open position, An overflow prevention valve disposed upstream of the slide valve in the gas flow direction, and disposed between the slide valve and the overflow prevention valve in the gas flow direction, the closed position and the open position And a reset means for performing a reset operation for resetting the overflow prevention valve by the movement of the slide valve between the gas valve and the gas stopper.

上記のようなガス栓としてのガスコンセントは、ガス管が接続されたガス接続具をガス栓本体に装着することで、ガス接続具に備えられた押圧部にてスライド弁を閉じ位置からガス流通路の上流側の開き位置まで押圧してガス流通路を開弁してガス接続具に接続されたガス器具へのガス供給を行う。スライド弁は、付勢部材により閉じ位置に復帰するように付勢されているので、ガス接続具をガス栓本体から取り外すことで、スライド弁に対する押圧部による押圧が解除されて、付勢部材の付勢力によりスライド弁が閉じ位置に復帰してガス器具へのガス供給が停止される。   The gas outlet as a gas plug as described above is a gas flow from the position where the slide valve is closed at the pressing part provided in the gas connector by attaching the gas connector to which the gas pipe is connected to the gas plug body. The gas is supplied to the gas appliance connected to the gas connector by opening the gas flow path by pressing to the opening position on the upstream side of the path. Since the slide valve is urged so as to return to the closed position by the urging member, by removing the gas connector from the gas plug main body, the pressing by the pressing portion on the slide valve is released, and the urging member The slide valve returns to the closed position by the urging force, and the gas supply to the gas appliance is stopped.

このようなガス栓では、ガス接続具に接続されたガス管が破れる等により一定以上の流量のガスが流れることがあるので、このような場合に、ガス供給を停止する必要がある。そこで、従来、ガス流通路のガス流量が一定以上となると、その一定以上のガス流量の流動圧により、初期位置からガス流通路を閉じる作動位置に移動する過流出防止弁が備えられている。これは、過流出防止弁が作動位置に移動することでガスの流通が阻止されるものであるが、ガス器具へのガス供給を再開させるためには、過流出防止弁を作動位置から初期位置に復帰させることが必要である。
そこで、使用者によってガス接続具をガス栓本体から取り外すという動作が行われることで、過流出防止弁における***作部をガス流通路の上流側へ押圧するリセット操作を行うリセット手段を備えており、リセット手段によるリセット操作によって過流出防止弁を作動位置から初期位置に復帰させるようにしている（例えば、特許文献１参照。）。
そして、リセット手段は、ガス接続具のガス栓本体からの取り外しによりリセット操作を行うだけでなく、ガス接続具がガス栓本体に装着されている場合には、リセット操作を解除しておき、過流出防止弁の初期位置から作動位置への移動を許容しておくことが必要である。 In such a gas stopper, a gas having a flow rate higher than a certain level may flow due to a broken gas pipe connected to the gas connector, and in such a case, it is necessary to stop the gas supply. Therefore, conventionally, an overflow prevention valve is provided that moves from an initial position to an operating position that closes the gas flow passage when the gas flow rate in the gas flow passage becomes a certain level or higher, due to the flow pressure of the gas flow rate above the certain level. This is because the gas flow is blocked by moving the overflow prevention valve to the operating position, but in order to restart the gas supply to the gas appliance, the overflow prevention valve is moved from the operating position to the initial position. It is necessary to return to
Therefore, the operation of removing the gas connector from the gas plug main body is performed by the user, thereby providing a reset means for performing a reset operation for pressing the operated portion of the overflow prevention valve to the upstream side of the gas flow passage. The overflow prevention valve is returned from the operating position to the initial position by a reset operation by the reset means (see, for example, Patent Document 1).
The reset means not only performs the reset operation by removing the gas connector from the gas stopper body, but also releases the reset operation when the gas connector is attached to the gas stopper body. It is necessary to allow movement of the outflow prevention valve from the initial position to the operating position.

特許文献１に記載のガス栓では、リセット手段が、ガス流通路のガス流通方向に直交する流路径方向に沿う軸心周りに揺動自在なＬ字状の第１レバーと第２レバーとを備えている。第１レバーは、ガス栓本体にガス接続具が装着された場合に、スライド弁の上流側端部に備えられた押し用突部によってガス流通路の上流側に押圧されて、第２レバーの揺動を規制する規制位置からガス流通路の上流側に揺動されて第２レバーの揺動を許容している。第２レバーは、作動位置に移動することでガス流通路の下流側に突出された過流出防止弁の軸部をガス流通路の上流側へ押圧する側に揺動するように付勢手段により付勢されている。ガス栓本体にガス接続具が装着されている場合には、第１レバーによって第２レバーの揺動を規制することで、過流出防止弁の軸部がガス流通路の下流側へ突出する突出代を確保して、過流出防止弁の軸部をガス流通路の上流側に押圧するリセット操作を解除している。このようにリセット操作を解除することで、過流出防止弁が初期位置から作動位置へ移動できることになる。ガス栓本体からガス接続具が取り外された場合には、押し用突部が第１レバーを押圧してガス流通路の上流側に揺動させることで第２レバーを付勢力により揺動させ、過流出防止弁の軸部をガス流通路の上流側に押圧するリセッ
ト操作を行い、過流出防止弁を作動位置から初期位置に復帰させている。 In the gas stopper described in Patent Document 1, the reset means includes an L-shaped first lever and a second lever that are swingable about an axis along a flow path radial direction orthogonal to the gas flow direction of the gas flow passage. I have. The first lever is pushed upstream of the gas flow passage by the pushing protrusion provided at the upstream end of the slide valve when the gas connector is mounted on the gas stopper body, and the second lever The second lever is allowed to swing by swinging from the restriction position for restricting the swing to the upstream side of the gas flow passage. The second lever is moved by the urging means so as to swing to the side pressing the upstream portion of the gas flow passage to the shaft portion of the overflow prevention valve protruding to the downstream side of the gas flow passage by moving to the operating position. It is energized. When a gas connector is mounted on the gas plug body, the shaft of the overflow prevention valve protrudes downstream of the gas flow passage by restricting the swing of the second lever by the first lever. The reset operation which presses the axial part of an excessive outflow prevention valve to the upstream of a gas flow path is ensured, and the allowance is canceled. By canceling the reset operation in this way, the overflow prevention valve can be moved from the initial position to the operating position. When the gas connector is removed from the gas plug body, the pushing protrusion presses the first lever and swings to the upstream side of the gas flow passage, thereby swinging the second lever by the biasing force, A reset operation for pressing the shaft portion of the overflow prevention valve to the upstream side of the gas flow passage is performed to return the overflow prevention valve from the operating position to the initial position.

一方、上記のようなガス栓として、ガス栓本体へのガス接続具の装着とは関係なく、操作つまみ等の操作部に対する回転操作に伴って開閉弁である回動弁を回転させて開閉を行ってガスの供給及び停止を切り替える所謂回転式のガス栓（例えば、特許文献２を参照。）などが知られている。また、ガスコンロ等に内蔵されガス流入路とガス流出路との間の開閉を行ってガスの供給及び停止を切り替える開閉弁として、操作ボタン等の操作部に対する押圧操作に伴って開閉弁であるスライド弁をスライドさせて開閉を行う所謂プッシュプッシュ式の開閉弁（例えば、特許文献３を参照。）などが知られており、上記ガス栓についても、この開閉弁と同様にプッシュプッシュ式に構成することが望まれている。   On the other hand, as a gas stopper as described above, regardless of the attachment of the gas connector to the gas stopper main body, the rotary valve, which is an opening / closing valve, is rotated to open and close in accordance with the rotation operation of the operation portion such as the operation knob. A so-called rotary gas stopper (see, for example, Patent Document 2) that performs gas supply and stop switching is known. In addition, as an open / close valve that opens and closes between a gas inflow path and a gas outflow path that is built in a gas stove or the like and switches between supply and stop of gas, a slide that is an open / close valve in accordance with a pressing operation on an operation unit such as an operation button A so-called push-push type opening / closing valve (see, for example, Patent Document 3) that opens and closes by sliding the valve is known, and the gas stopper is also configured as a push-push type in the same manner as this opening / closing valve. It is hoped that.

上記特許文献１に記載のガス栓では、リセット手段として、押し用突部、及び、付勢手段に加えて、第１レバーと第２レバーとの２つの揺動部材を設けなければならず、構成の複雑化及び部材点数の増加を招いている。
また、第１レバーについては、押し用突部にて押圧できるとともに、第２レバーの揺動を規制できる位置に配置しなければならない。第２レバーについても、第１レバーにて揺動が規制されるとともに、過流出防止弁の軸部をガス流通路の上流側に押圧できる位置に配置しなければならない。したがって、第１レバーと第２レバーの配置位置を精度よく調整しなければならず、リセット手段によるリセット操作及びリセット操作の解除を適切に行い難いものとなっていた。 In the gas stopper described in Patent Document 1, in addition to the pushing protrusion and the urging means, two rocking members of the first lever and the second lever must be provided as the resetting means. This complicates the configuration and increases the number of members.
In addition, the first lever must be arranged at a position where it can be pressed by the pressing projection and the swing of the second lever can be restricted. The second lever must also be disposed at a position where the swinging of the second lever is restricted by the first lever and the shaft portion of the overflow prevention valve can be pressed upstream of the gas flow passage. Therefore, the arrangement positions of the first lever and the second lever have to be adjusted with high precision, and it is difficult to appropriately perform the reset operation and the reset operation by the reset means.

本発明は、かかる点に着目してなされたものであり、その目的は、リセット手段の構成の簡素化及び部材点数の減少を図り、リセット手段によるリセット操作及びリセット操作の解除を適切に行うことができるガス栓を提供する点にある。   The present invention has been made paying attention to such a point, and its purpose is to simplify the configuration of the reset means and reduce the number of members, and to appropriately perform the reset operation and reset operation by the reset means. It is in providing a gas stopper that can be used.

上記目的を達成するための本発明のガス栓は、
ガス流通路が内部に形成された筒状のガス栓本体に、閉じ位置と開き位置との間で前記ガス栓本体の軸方向に移動自在なスライド弁と、前記ガス流通路のガス流通方向で前記スライド弁よりも上流側に配置された過流出防止弁と、前記ガス流通方向で前記スライド弁と前記過流出防止弁との間に配置されて、前記閉じ位置と前記開き位置との間での前記スライド弁の移動により前記過流出防止弁をリセットさせるリセット操作を行うリセット手段とが備えられているガス栓であって、
前記リセット操作は、前記過流出防止弁における***作部を前記ガス流通路の上流側へ押圧する操作であり、
前記過流出防止弁を収容する過流出防止弁収容部材が設けられ、
前記***作部は、前記過流出防止弁収容部材の前記ガス流通路のガス流通方向での移動に伴って移動自在に設けられ、
前記リセット手段は、前記過流出防止弁収容部材を、前記スライド弁の移動に伴って前記ガス流通路のガス流通方向に移動自在とし、その過流出防止弁収容部材の前記ガス流通方向での移動により前記***作部に当接させて前記リセット操作を行なう当接部材を備えている点にある。 To achieve the above object, the gas stopper of the present invention comprises:
A cylindrical gas stopper body having a gas flow passage formed therein, a slide valve movable in the axial direction of the gas stopper body between a closed position and an open position, and a gas flow direction of the gas flow passage An overflow prevention valve disposed upstream of the slide valve, and disposed between the slide valve and the overflow prevention valve in the gas flow direction, between the closed position and the open position. A gas stopper provided with reset means for performing a reset operation to reset the overflow prevention valve by movement of the slide valve,
The reset operation is an operation of pressing the operated portion of the overflow prevention valve to the upstream side of the gas flow path,
An overflow prevention valve housing member for housing the overflow prevention valve is provided;
The operated portion is provided movably along with the movement of the gas flow passage in the gas flow direction of the overflow prevention valve housing member,
The reset means allows the overflow prevention valve housing member to move freely in the gas flow direction of the gas flow passage as the slide valve moves, and the overflow prevention valve housing member moves in the gas flow direction. Therefore, a contact member that performs the reset operation by contacting the operated portion is provided.

上記特徴構成によれば、過流出防止弁を収容する過流出防止弁収容部材が、スライド弁の移動に伴ってガス流通路のガス流通方向に移動自在とされているので、スライド弁を移動させることで過流出防止弁収容部材が移動し、その過流出防止弁収容部材の移動によって***作部を移動させて当接部材に当接させることでリセット操作を行なうことができる。このように、スライド弁の移動によって、当接部材への***作部の当接を適切に行うことができるので、リセット手段によるリセット操作を容易かつ適切に行うことができる。   According to the above characteristic configuration, the overflow prevention valve housing member that houses the overflow prevention valve is movable in the gas flow direction of the gas flow passage as the slide valve moves, so the slide valve is moved. Thus, the excessive outflow prevention valve accommodating member moves, and the reset operation can be performed by moving the operated portion by the movement of the excessive outflow prevention valve accommodating member and bringing it into contact with the abutting member. As described above, since the operated portion can be appropriately brought into contact with the contact member by the movement of the slide valve, the reset operation by the reset means can be easily and appropriately performed.

本発明のガス栓の更なる特徴構成は、
前記リセット手段は、前記スライド弁と前記過流出防止弁収容部材とを連結する連結部材を備えるとともに、前記開き位置から前記閉じ位置への前記スライド弁の移動に伴って前記***作部に当接して前記リセット操作を行う操作位置に固定されて、前記閉じ位置から前記開き位置への前記スライド弁の移動に伴って前記***作部が離間して前記リセット操作を解除する固定部材を前記当接部材として備えている点にある。 Further features of the gas stopper of the present invention are as follows:
The reset means includes a connecting member that connects the slide valve and the overflow prevention valve housing member, and abuts on the operated portion as the slide valve moves from the open position to the closed position. The fixed member that is fixed to the operation position for performing the reset operation and that releases the reset operation when the operated portion is separated as the slide valve moves from the closed position to the open position. It is in the point provided as a member.

リセット手段は、スライド弁と過流出防止弁収容部材とを連結する連結部材を備えるので、スライド弁と過流出防止弁収容部材を一体として軸方向に移動させることができる。また、リセット手段としては、連結部材にてスライド弁と過流出防止弁収容部材とを連結するとともに、当接部材としての固定部材を備えるだけでよく、リセット手段の構成の簡素化及び部材点数の減少を図ることができる。そして、過流出防止弁収容部材は、連結部材によってスライド弁に連結されているので、スライド弁の移動によって、リセット操作を行う操作位置に固定されている固定部材への***作部の当接、及び、固定部材からの***作部の離間を適切に行うことができるので、リセット手段によるリセット操作及びリセット操作の解除を適切に行うことができる。   Since the reset means includes a connecting member that connects the slide valve and the overflow prevention valve housing member, the slide valve and the overflow prevention valve housing member can be moved together in the axial direction. Further, as the reset means, it is only necessary to connect the slide valve and the excessive outflow prevention valve housing member with a connecting member, and to provide a fixing member as a contact member, simplifying the configuration of the reset means and the number of members. Reduction can be achieved. And since the excessive outflow prevention valve housing member is connected to the slide valve by the connecting member, the contact of the operated portion to the fixing member fixed at the operation position for performing the reset operation by the movement of the slide valve, And since the to-be-operated part can be appropriately separated from the fixing member, the reset operation by the reset means and the release of the reset operation can be appropriately performed.

本発明のガス栓の更なる特徴構成は、
前記固定部材は、前記ガス流通路のガス流通方向に対して直交する流路径方向の全体に亘る板状に形成され、
前記固定部材に、ガス流通を許容する流通孔が形成されており、前記連結部材は、前記流通孔を通して前記スライド弁と前記過流出防止弁収容部材とを連結している点にある。 Further features of the gas stopper of the present invention are as follows:
The fixing member is formed in a plate shape over the entire flow path radial direction orthogonal to the gas flow direction of the gas flow path,
A flow hole that allows gas flow is formed in the fixing member, and the connection member connects the slide valve and the overflow prevention valve housing member through the flow hole.

本特徴構成によれば、固定部材は、前記ガス流通路のガス流通方向に対して直交する流路径方向の全体に亘る板状に形成されているので、固定部材と当接してリセット操作を行なう***作部が、ガス流通路の流路径方向のいずれの場所に設けられていても固定部材と当接させることができ、リセット操作を確実に行なうことができる。
また、固定部材に、ガス流通を許容する流通孔が形成されており、これによって、固定部材の上流側から下流側へガスを流通させることができる。また、連結部材は、流通孔を通してスライド弁と過流出防止弁収容部材とを連結しているので、固定部材の上流側に位置する過流出防止弁収容部材と、下流側に位置するスライド弁とを連結する連結部材を流通孔に通すことで、連結部材を通すための貫通口を新たに固定部材に設ける必要がなくなり、リセット手段の構成の簡素化が可能となる。 According to this characteristic configuration, the fixing member is formed in a plate shape over the entire flow path radial direction orthogonal to the gas flow direction of the gas flow passage, and thus performs a reset operation in contact with the fixing member. Regardless of where the operated portion is provided in the radial direction of the gas flow passage, it can be brought into contact with the fixing member, and the reset operation can be performed reliably.
In addition, a flow hole allowing gas flow is formed in the fixing member, whereby gas can flow from the upstream side to the downstream side of the fixing member. Further, since the connecting member connects the slide valve and the overflow prevention valve housing member through the flow hole, the overflow prevention valve housing member located on the upstream side of the fixing member, and the slide valve located on the downstream side By passing the connecting member that connects the two through the flow hole, there is no need to newly provide a through-hole for passing the connecting member in the fixing member, and the configuration of the reset means can be simplified.

本発明のガス栓の更なる特徴構成は、
前記過流出防止弁収容部材は、その内部にガスが流通する流路が形成された筒状に形成され、前記ガス流通路の内壁部を前記ガス栓本体の軸方向に気密状態で摺動自在に備えられており、前記過流出防止弁は、前記過流出防止弁収容部材の内部に形成された流路を開閉するように設けられている点にある。 Further features of the gas stopper of the present invention are as follows:
The overflow prevention valve housing member is formed in a cylindrical shape having a flow passage through which gas flows, and the inner wall portion of the gas flow passage is slidable in an airtight state in the axial direction of the gas plug body. The overflow prevention valve is provided so as to open and close a flow path formed inside the overflow prevention valve housing member.

本特徴構成によれば、過流出防止弁収容部材はガス流通路の内壁部をガス栓本体の軸方向に気密状態で摺動自在に備えられるので、ガス流通路の内壁部と過流出防止弁収容部材との間にガスが流通することを防止しつつ、過流出防止弁収容部材のガス流通路内のガス流通方向における動きを利用して、リセット手段によるリセット操作及びリセット操作の解除を行うことができる。
また、過流出防止弁は、過流出防止弁収容部材の内部に形成された流路を開閉するように設けられているので、過流出防止弁にて流路を開閉するための構成の簡素化を図りながら、過流出防止弁収容部材に過流出防止弁を収容させることができる。 According to this feature configuration, the overflow prevention valve housing member is provided with the inner wall portion of the gas flow passage so as to be slidable in an airtight state in the axial direction of the gas plug body. The reset operation by the reset means and the release of the reset operation are performed using the movement in the gas flow direction in the gas flow path of the overflow prevention valve housing member while preventing the gas from flowing between the housing and the housing member. be able to.
Moreover, since the overflow prevention valve is provided to open and close the flow path formed inside the overflow prevention valve housing member, the configuration for opening and closing the flow path with the overflow prevention valve is simplified. The overflow prevention valve can be accommodated in the overflow prevention valve housing member.

本発明のガス栓の更なる特徴構成は、
前記***作部は、前記過流出防止弁収容部材よりも前記ガス流通路の下流側に突出する状態で備えられている点にある。 Further features of the gas stopper of the present invention are as follows:
The operated portion is provided in a state of projecting further downstream of the gas flow passage than the overflow prevention valve housing member.

本特徴構成によれば、***作部は、過流出防止弁収容部材よりもガス流通路の下流側に突出しているので、リセット操作の際に、***作部が配置された過流出防止弁収容部材が下流側に移動して固定部材と当接するときにおいて、過流出防止弁収容部材よりも先に***作部が当接されるので、確実にリセット操作を行うことができる。   According to this characteristic configuration, the operated portion protrudes further downstream of the gas flow passage than the overflow prevention valve housing member, so that the overflow prevention valve housing in which the operated portion is disposed during the reset operation. When the member moves downstream and comes into contact with the fixed member, the operated portion comes into contact with the overflow prevention valve housing member, so that the reset operation can be performed reliably.

本発明のガス栓の更なる特徴構成は、
前記ガス流通路は、上流側から順に、前記過流出防止弁、前記リセット手段、前記スライド弁を備えて、前記ガス栓本体の軸方向に沿う直線状に設けられている点にある。 Further features of the gas stopper of the present invention are as follows:
The gas flow passage is provided with the overflow prevention valve, the reset means, and the slide valve in order from the upstream side, and is provided in a straight line along the axial direction of the gas plug body.

ガス栓本体２に対して装着及び取り外し自在なガス接続具１００について説明する。このガス接続具１００は、既に公知の構成であるので、詳細な説明は省略して簡単に説明する。
ガス接続具１００は、第１コイルバネ１０１により前方側（図１及び図２中Ｘ方向の右側）に付勢される突出部材１０２と、ロック用ボール１０３と、ロック用ボール１０３の位置を径方向の内側から規制するとともに、ガス栓本体２の先端部に当接して押圧されて引退する内径部材１０４と、ガス栓本体２に装着される際にスライド弁Ｇを押圧する棒状の押圧部１０５とを備えている。 The gas connector 100 that can be attached to and detached from the gas plug body 2 will be described. Since the gas connector 100 has a known configuration, a detailed description thereof will be omitted and will be briefly described.
In the gas connector 100, the positions of the protruding member 102, the locking ball 103, and the locking ball 103 that are biased forward by the first coil spring 101 (the right side in the X direction in FIGS. 1 and 2) are set in the radial direction. An inner diameter member 104 that is pressed against the front end of the gas stopper main body 2 and is retracted, and a rod-like pressing portion 105 that presses the slide valve G when the gas stopper main body 2 is mounted. It has.

ガス接続具１００をガス栓本体２に装着する場合には、図２に示すように、ガス栓本体２の先端部が内径部材１０４に当接して内径部材１０４を第２コイルバネ１０６の付勢力に抗して引退させる。内径部材１０４の引退によりロック用ボール１０３が径方向の内側に移動して、ガス栓本体２に形成された嵌込溝２ａにロック用ボール１０３が嵌り込んで、突出部材１０２が第１コイルバネ１０１の付勢力により前方側（図２中Ｘ方向の右側）に突出する。このように、ガス接続具１００のロック用ボール１０３がガス栓本体２の嵌込溝２ａに嵌り込むことで、ガス接続具１００がガス栓本体２に外嵌装着される。ガス接続具１００がガス栓本体２に装着される際に、ガス接続具１００の押圧部１０５にてスライド弁Ｇが押圧される。この押圧部１０５によるスライド弁Ｇに対する押圧によって、第１弁体Ｇ１と第２弁体Ｇ２の両者が、ガス栓本体２の軸方向に沿ってガス流通路１の上流側（図２中Ｘ方向の右側）に移動して、閉じ位置から開き位置に移動することになり、ガス流通路１が開弁されてガス器具へのガス供給が行われる。   When the gas connector 100 is attached to the gas plug main body 2, as shown in FIG. 2, the distal end portion of the gas plug main body 2 abuts against the inner diameter member 104, so that the inner diameter member 104 is biased by the second coil spring 106. Retire against. When the inner diameter member 104 is retracted, the locking ball 103 moves inward in the radial direction, the locking ball 103 is fitted into the fitting groove 2 a formed in the gas plug main body 2, and the protruding member 102 is the first coil spring 101. It protrudes to the front side (right side in the X direction in FIG. 2) by the urging force. In this way, the locking ball 103 of the gas connector 100 is fitted into the fitting groove 2 a of the gas plug body 2, so that the gas connector 100 is externally mounted on the gas plug body 2. When the gas connector 100 is attached to the gas plug body 2, the slide valve G is pressed by the pressing portion 105 of the gas connector 100. By pressing against the slide valve G by the pressing portion 105, both the first valve body G1 and the second valve body G2 are located upstream of the gas flow passage 1 along the axial direction of the gas plug body 2 (X direction in FIG. 2). To the open position, the gas flow passage 1 is opened, and gas supply to the gas appliance is performed.

ガス接続具１００をガス栓本体２から取り外す場合には、突出部材１０２を第１コイルバネ１０１の付勢力に抗して押込操作することで、嵌込溝２ａへのロック用ボール１０３の嵌り込みが解除されるので、ガス接続具１００をガス栓本体２から取り外すことができる。そして、ガス接続具１００をガス栓本体２から取り外すと、スライド弁Ｇに対する押圧部１０５による押圧が解除され、第１弁体Ｇ１と第２弁体Ｇ２の両者が、付勢部材Ｆ１，Ｆ２の付勢力によって、ガス栓本体２の軸方向に沿ってガス流通路１の下流側（図２中Ｘ方向の左側）に移動して、開き位置から閉じ位置に復帰されてガス流通路１が閉弁される。   When the gas connector 100 is removed from the gas plug body 2, the locking member 103 is fitted into the fitting groove 2a by pushing the protruding member 102 against the urging force of the first coil spring 101. Since it is released, the gas connector 100 can be removed from the gas plug body 2. Then, when the gas connector 100 is removed from the gas plug body 2, the pressing by the pressing portion 105 against the slide valve G is released, and both the first valve body G1 and the second valve body G2 are connected to the urging members F1, F2. The urging force moves along the axial direction of the gas plug body 2 to the downstream side of the gas flow passage 1 (left side in the X direction in FIG. 2), returns from the open position to the closed position, and the gas flow passage 1 is closed. To be spoken.

過流出防止機構Ｈは、過流出防止弁Ｈ２を収容する過流出防止弁収容部材Ｈａを備えており、その過流出防止弁収容部材Ｈａは、ガス流通路１の第２流路部位１ｂの内周面に気密状態で摺動自在に備えられた筒状部材Ｈ１と、筒状部材Ｈ１の内部において過流出防止弁Ｈ２及び***作部材Ｈ３（***作部に相当する）を支持する支持部材Ｈ４とで構成されている。過流出防止弁収容部材Ｈａには、内部にガスを流通する流路が形成されている。   The overflow prevention mechanism H includes an overflow prevention valve housing member Ha that houses the overflow prevention valve H2, and the overflow prevention valve housing member Ha is included in the second flow path portion 1b of the gas flow passage 1.

It is provided to be freely movable. Then, at the downstream end of the gas flow passage 1 of the overflow prevention valve housing member Ha, the operated member H3 that receives the pressing operation from the resetting means R to the upstream side as the resetting operation is a gas plug by the support member H4. The main body 2 is supported so as to be movable in the axial direction. Thus, by providing the operated member H3 in the overflow prevention valve housing member Ha, the operated member H3 is moved along with the movement of the gas flow passage 1 of the overflow prevention valve housing member Ha in the gas flow direction. It is provided freely.

過流出防止弁Ｈ２は、第３付勢部材Ｆ３によって、作動位置よりも上流側の初期位置に復帰するように付勢されており、保持部材Ｈ５に当接することで初期位置に位置保持されて、過流出防止弁収容部材Ｈａの内部に形成された流路を開弁している。そして、過流出防止弁Ｈ２は、ガス流量が一定以上の過流量となると、そのガス流量の流動圧によって初期位置から作動位置に移動自在に備えられており、作動位置に移動して過流出防止弁Ｈ２が弁座部Ｈ６に着座すると、過流出防止弁収容部材Ｈａの内部に形成された流路を閉じた状態となり、ガスの流通が阻止される。   The overflow prevention valve H2 is urged by the third urging member F3 so as to return to the initial position upstream of the operating position, and is held at the initial position by contacting the holding member H5. The flow path formed inside the overflow prevention valve housing member Ha is opened. The overflow prevention valve H2 is provided so as to be movable from the initial position to the operating position by the flow pressure of the gas flow rate when the gas flow rate exceeds a certain level. When the valve H2 is seated on the valve seat portion H6, the flow path formed inside the overflow prevention valve housing member Ha is closed, and the gas flow is blocked.

支持部材Ｈ４は、その内部がガス栓本体２の軸方向に貫通する略円筒状に形成されている。支持部材Ｈ４の上流側部位は、過流出防止弁Ｈ２の軸部Ｈ２ａに外嵌して、ガス栓本体２の軸方向に移動自在に過流出防止弁Ｈ２を支持している。支持部材Ｈ４の下流側部位は、***作部材Ｈ３に外嵌して、ガス栓本体２の軸方向に移動自在に***作部材Ｈ３を支持している。ここで、***作部材Ｈ３は過流出防止弁収容部材Ｈａよりもガス流通路１の下流側に突出する状態で備えられている。   The support member H <b> 4 is formed in a substantially cylindrical shape whose inside penetrates in the axial direction of the gas plug main body 2. The upstream portion of the support member H4 is externally fitted to the shaft portion H2a of the overflow prevention valve H2, and supports the overflow prevention valve H2 so as to be movable in the axial direction of the gas plug body 2. The downstream portion of the support member H4 is externally fitted to the operated member H3, and supports the operated member H3 so as to be movable in the axial direction of the gas plug body 2. Here, the operated member H3 is provided in a state of projecting to the downstream side of the gas flow passage 1 with respect to the excessive outflow prevention valve housing member Ha.

***作部材Ｈ３の上流側部位Ｈ３ａは、ガス栓本体２の軸方向に延びる棒状に形成されており、支持部材Ｈ４に内嵌されて、ガス栓本体２の軸方向に移動自在に支持されている。***作部材Ｈ３の下流側部位は、ガス流通路１の流路径方向の中央部に下流側に突出する頭部Ｈ３ｂが備えられた概略円錐状に形成されている。頭部Ｈ３ｂの径方向の外側には、径方向の外側に延びる脚部Ｈ３ｃが備えており、その脚部Ｈ３ｃの先端部が筒状部材Ｈ１に形成された係合溝Ｈ１ａに係合されている。図示は省略するが、脚部Ｈ３ｃは、周方向で間隔を隔てて複数備えられており、脚部Ｈ３ｃ同士の間をガスが流通している。***作部材Ｈ３は、第４付勢部材Ｆ４によって下流側部位の頭部Ｈ３ｂが筒状部材Ｈ１からガス流通路１の下流側に突出する突出位置に復帰するように付勢されており、脚部Ｈ３ｃが係合溝Ｈ１ａの端部に当接して突出位置に位置保持されている。   The upstream portion H3a of the operated member H3 is formed in a rod shape extending in the axial direction of the gas stopper main body 2, is fitted into the support member H4, and is supported so as to be movable in the axial direction of the gas stopper main body 2. Yes. The downstream portion of the operated member H3 is formed in a substantially conical shape provided with a head portion H3b that protrudes downstream in the central portion of the gas flow passage 1 in the flow path radial direction. A leg H3c extending outward in the radial direction is provided on the outer side in the radial direction of the head H3b, and a distal end portion of the leg H3c is engaged with an engagement groove H1a formed in the cylindrical member H1. Yes. Although illustration is omitted, a plurality of leg portions H3c are provided at intervals in the circumferential direction, and gas flows between the leg portions H3c. The operated member H3 is urged by the fourth urging member F4 so that the head portion H3b at the downstream side portion returns from the cylindrical member H1 to the protruding position where it protrudes to the downstream side of the gas flow passage 1. The portion H3c abuts against the end of the engagement groove H1a and is held at the protruding position.

支持部材Ｈ４は、初期位置に位置する過流出防止弁Ｈ２と突出位置に位置する***作部材Ｈ３との間に、初期位置から作動位置までの移動量に相当する間隔を隔てる状態で、過流出防止弁Ｈ２と***作部材Ｈ３をガス栓本体２の軸方向に移動自在に支持している。これにより、過流出防止機構Ｈは、突出位置に位置する***作部材Ｈ３が押圧されるリセット操作が解除されている場合に、過流出防止弁Ｈ２の初期位置から作動位置への移動を許容している。
一方、一定以上のガス流量の流動圧によって過流出防止弁Ｈ２が作動位置に移動すると、作動位置に移動した過流出防止弁Ｈ２と突出位置に位置する***作部材Ｈ３とが当接するようになっている。突出位置に位置する***作部材Ｈ３が押圧されるリセット操作を受けた場合には、***作部材Ｈ３と過流出防止弁Ｈ２との当接により***作部材Ｈ３と過流出防止弁Ｈ２が一体的にガス流通路１の上流側へ移動することになり、過流出防止弁Ｈ２の弁座部Ｈ６への着座が解除されて、上流側からのガス圧が解除され、第３付勢部材Ｆ３の付勢力によって過流出防止弁Ｈ２が初期位置に復帰される。このようにして、過流出防止機構Ｈは、突出位置に位置する***作部材Ｈ３が押圧されるリセット操作を受けた場合に、過流出防止弁Ｈ２を初期位置に復帰させている。 The support member H4 has an excessive outflow in a state in which an interval corresponding to the amount of movement from the initial position to the operating position is separated between the excessive outflow prevention valve H2 positioned at the initial position and the operated member H3 positioned at the protruding position. The prevention valve H2 and the operated member H3 are supported so as to be movable in the axial direction of the gas plug body 2. Thereby, the excessive outflow prevention mechanism H allows the movement of the excessive outflow prevention valve H2 from the initial position to the operating position when the reset operation for pressing the operated member H3 located in the protruding position is released. ing.
On the other hand, when the overflow prevention valve H2 is moved to the operating position by the flow pressure at a gas flow rate above a certain level, the overflow prevention valve H2 that has moved to the operating position comes into contact with the operated member H3 that is located at the protruding position. ing. When a reset operation is performed in which the operated member H3 located at the protruding position is pressed, the operated member H3 and the excessive outflow prevention valve H2 are integrated by the contact between the operated member H3 and the excessive outflow prevention valve H2. To the upstream side of the gas flow passage 1, the seating of the excessive outflow prevention valve H2 on the valve seat portion H6 is released, the gas pressure from the upstream side is released, and the third urging member F3 The overflow prevention valve H2 is returned to the initial position by the urging force. In this way, the excessive outflow prevention mechanism H returns the excessive outflow prevention valve H2 to the initial position when it receives a reset operation in which the operated member H3 positioned at the protruding position is pressed.

リセット手段Ｒは、ガス接続具１００のガス栓本体２からの取り外しが行われた場合に、ガス栓本体２の軸方向でのスライド弁Ｇの開き位置から閉じ位置への移動に伴って、過流出防止弁Ｈ２を初期位置に復帰させるため（リセットさせるために）に***作部材Ｈ３の頭部Ｈ３ｂを押圧するリセット操作を行うように構成されている。   When the gas connector 100 is detached from the gas stopper main body 2, the reset means R is excessive as the slide valve G moves from the open position to the closed position in the axial direction of the gas stopper main body 2. In order to return (to reset) the outflow prevention valve H2 to the initial position, a reset operation is performed to press the head H3b of the operated member H3.

リセット手段Ｒは、スライド弁Ｇと過流出防止機構Ｈの過流出防止弁収容部材Ｈａとを連結してガス栓本体２の軸方向に一体的に移動自在とする連結部材Ｒ２と、スライド弁Ｇが閉じ位置に位置する場合に***作部材Ｈ３を押圧してリセット操作を行う操作位置に固定された当接部材としての固定部材Ｒ１とを備えている。   The reset means R connects the slide valve G and the overflow prevention valve housing member Ha of the overflow prevention mechanism H so as to be integrally movable in the axial direction of the gas plug body 2 and the slide valve G.

It is fixed. A flow hole R1a that allows gas flow is formed in the fixing member R1. Further, the connecting member R2 connects the first valve body G1 of the slide valve G and the overflow prevention valve housing member Ha through the flow hole R1a.

連結部材Ｒ２は、ガス流通路１の軸方向（図中Ｘ方向）に延びる棒状体として形成されて、固定部材Ｒ１を摺動自在に貫通しつつ、下流側に位置する第２弁体Ｇ２と上流側に位置する過流出防止弁収容部材Ｈａとを連結している。これにより、図３（ｄ）に示すように、スライド弁Ｇの開き位置から閉じ位置への移動に伴って、連結部材Ｒ２により一体的に形成されている過流出防止弁収容部材Ｈａ（Ｈ１及びＨ４）が下流側へ移動して、過流出防止弁収容部材Ｈａに備えられる***作部材Ｈ３の頭部Ｈ３ｂが固定部材Ｒ１に当接して押圧されることでリセット操作が行なわれる。一方で、スライド弁Ｇの閉じ位置から開き位置への移動に伴って、***作部材Ｈ３が固定部材Ｒ１から離れることでリセット操作が解除される。   The connecting member R2 is formed as a rod-like body extending in the axial direction (X direction in the drawing) of the gas flow passage 1, and slidably penetrates the fixing member R1 and is positioned downstream of the second valve body G2. The excessive outflow prevention valve accommodation member Ha located in the upstream is connected. As a result, as shown in FIG. 3 (d), as the slide valve G moves from the open position to the closed position, the excessive outflow prevention valve housing member Ha (H1 and H1) formed integrally by the connecting member R2. H4) moves downstream, and the reset operation is performed by pressing the head H3b of the operated member H3 provided in the overflow prevention valve housing member Ha in contact with the fixing member R1. On the other hand, with the movement of the slide valve G from the closed position to the open position, the operated member H3 is separated from the fixed member R1, and the reset operation is released.

図３（ａ）に示すように、ガス接続具１００をガス栓本体２から取り外している場合には、スライド弁Ｇが閉じ位置に位置しており、ガス流通路１がスライド弁Ｇにて閉弁されている。この状態においては、固定部材Ｒ１によって過流出防止弁収容部材Ｈａに備えられた***作部材Ｈ３の頭部Ｈ３ｂが押圧されてリセット操作が行われている。このリセット操作によって過流出防止弁Ｈ２が初期位置に復帰される。図３（ａ）では、過流出防止弁Ｈ２については初期位置に復帰された状態を示している。   As shown in FIG. 3 (a), when the gas connector 100 is removed from the gas plug body 2, the slide valve G is in the closed position, and the gas flow passage 1 is closed by the slide valve G. It is spoken. In this state, the reset operation is performed by pressing the head portion H3b of the operated member H3 provided in the overflow prevention valve housing member Ha by the fixing member R1. This reset operation returns the excessive outflow prevention valve H2 to the initial position. FIG. 3A shows a state in which the excessive outflow prevention valve H2 is returned to the initial position.

図３（ｂ）に示すように、ガス接続具１００をガス栓本体２に装着すると、ガス接続具１００の押圧部１０５がスライド弁Ｇをガス流通路１の上流側に押圧して、スライド弁Ｇが閉じ位置から開き位置に移動してガス流通路１を開弁させる。このとき、スライド弁Ｇの移動に伴って***作部材Ｈ３を備えた過流出防止弁収容部材Ｈａが上流側へ移動して、固定部材Ｒ１によって***作部材Ｈ３の頭部Ｈ３ｂを押圧するリセット操作が解除される。リセット操作が解除されると、***作部材Ｈ３は、第４付勢部材Ｆ４の付勢力によって頭部Ｈ３ｂが突出位置に復帰される。このようにして、***作部材Ｈ３が突出位置に復帰されると、***作部材Ｈ３と過流出防止弁Ｈ２との間に、過流出防止弁Ｈ２の初期位置から作動位置への移動を許容するスペースが形成される。   As shown in FIG. 3 (b), when the gas connector 100 is attached to the gas plug body 2, the pressing portion 105 of the gas connector 100 presses the slide valve G to the upstream side of the gas flow passage 1, and the slide valve G moves from the closed position to the open position to open the gas flow passage 1. At this time, with the movement of the slide valve G, the overflow prevention valve housing member Ha provided with the operated member H3 moves upstream, and the fixing member R1 presses the head H3b of the operated member H3. Is released. When the reset operation is released, the head H3b of the operated member H3 is returned to the protruding position by the urging force of the fourth urging member F4. In this way, when the operated member H3 is returned to the protruding position, the movement of the overflow prevention valve H2 from the initial position to the operating position is allowed between the operated member H3 and the overflow prevention valve H2. A space is formed.

図３（ｃ）に示すように、ガス流量が一定以上の過流量となると、そのガス流量の流動圧によって過流出防止弁Ｈ２がガス栓本体２の軸方向に沿ってガス流通路１の下流側に移動して、過流出防止弁Ｈ２が初期位置から作動位置へ移動する。これにより、過流出防止弁Ｈ２が作動位置に移動することでガス流通が阻止される。   As shown in FIG. 3 (c), when the gas flow rate exceeds a certain level, the overflow prevention valve H 2 is moved downstream of the gas flow passage 1 along the axial direction of the gas plug body 2 by the flow pressure of the gas flow rate. The overflow prevention valve H2 moves from the initial position to the operating position. Thereby, the gas flow is blocked by the excessive outflow prevention valve H2 moving to the operating position.

図３（ｄ）に示すように、ガス接続具１００をガス栓本体２から取り外すと、ガス接続具１００の押圧部１０５によるスライド弁Ｇに対するガス流通路１の上流側への押圧が解除されて、第１付勢部材Ｆ１及び第２付勢部材Ｆ２の付勢力によってスライド弁Ｇがガス栓本体２の軸方向に沿って開き位置から閉じ位置に移動する。このとき、スライド弁Ｇの移動に伴って***作部材Ｈ３を備えた過流出防止弁収容部材Ｈａが下流側へ移動して、固定部材Ｒ１に***作部材Ｈ３の頭部Ｈ３ｂが当接し、***作部材Ｈ３が押圧されるリセット操作が行われて、図３（ａ）に示すように、過流出防止弁Ｈ２が初期位置に復帰される。   As shown in FIG. 3 (d), when the gas connector 100 is removed from the gas plug body 2, the pressure of the gas connector 100 on the upstream side of the gas flow passage 1 against the slide valve G by the pressing portion 105 is released. The slide valve G moves from the open position to the closed position along the axial direction of the gas plug body 2 by the urging force of the first urging member F1 and the second urging member F2. At this time, as the slide valve G moves, the overflow prevention valve housing member Ha provided with the operated member H3 moves downstream, and the head H3b of the operated member H3 comes into contact with the fixed member R1, so that the A reset operation for pressing the operation member H3 is performed, and the excessive outflow prevention valve H2 is returned to the initial position as shown in FIG.

The L-shaped gas plug thus configured discharges the gas g flowing into the gas plug main body 2 from the bottom to the top in a horizontal direction, and is applied to a gas device (not shown) or the like disposed on the side. Supply. In the present embodiment, the gas stopper is not configured as the L-shaped gas stopper, but the crossing angle between the gas inlet path 1A and the gas outlet path 1B is appropriately set, for example, by providing the gas outlet path 1B obliquely downward. It can be modified.

〔弁機構部〕
ガス流入路１Ａ及びガス流出路１Ｂの何れか一方の特定ガス流通路をガス流入路１Ａとし、同特定ガス流通路の軸線である特定軸線をガス流入路１Ａの軸線Ｘとすると、弁機構部Ａは、当該特定ガス流通路であるガス流入路１Ａの弁収容部５に対する開口部１Ａａに形成された弁座部６と、同特定軸線である軸線Ｘに沿ってスライドして弁座部６に対して着座して当該開口部１Ａａを閉塞する閉じ位置と、軸線Ｘに沿ってスライドして弁座部６に対して離間して当該開口部１Ａａを開放する開き位置との間で変位するスライド弁Ｇ'とを有して構成されている。
即ち、スライド弁Ｇ'は、上下方向に配置されたガス流入路１Ａの軸線Ｘに沿って、上下方向にスライドする。そして、そのスライド範囲の上端位置が、スライド弁Ｇ'が弁座部６に着座して開口部１Ａａを閉塞する閉じ位置であり、同範囲の下端位置が、スライド弁Ｇ'が弁座部６に対して離間して当該開口部１Ａａを開放する開き位置となる。よって、本実施形態において、閉じ位置側とは上方側を示し、開き位置側とは下方側を示すことになる。
ここで、図８及び図９にはスライド弁Ｇ'が開き位置にある状態が示されており、図５及び図７にはスライド弁Ｇ'が閉じ位置にある状態が示されている。 (Valve mechanism)
When one of the gas inflow passage 1A and the gas outflow passage 1B is a gas inflow passage 1A, and a specific axis that is an axis of the specific gas flow passage is an axis X of the gas inflow passage 1A, the valve mechanism section A slides along the axis X which is the specific axis and the valve seat 6 formed in the opening 1Aa with respect to the valve accommodating part 5 of the gas inflow path 1A which is the specific gas flow path, and the valve seat 6 Between the closed position where the opening 1Aa is seated and the opening 1Aa slides along the axis X and is spaced apart from the valve seat 6 to open the opening 1Aa. And a slide valve G ′.
That is, the slide valve G ′ slides in the vertical direction along the axis X of the gas inflow passage 1A arranged in the vertical direction. The upper end position of the slide range is a closed position where the slide valve G ′ is seated on the valve seat portion 6 and closes the opening 1Aa. The lower end position of the slide range is the slide valve G ′. It becomes an opening position which spaces apart and opens the opening 1Aa. Therefore, in the present embodiment, the closed position side indicates the upper side, and the open position side indicates the lower side.
Here, FIGS. 8 and 9 show a state in which the slide valve G ′ is in the open position, and FIGS. 5 and 7 show a state in which the slide valve G ′ is in the closed position.

〔操作機構部〕
操作機構部Ｂは、操作者による操作部１１に対する下向きの押圧操作をスライド弁Ｇ'に伝達させて当該スライド弁Ｇ'と共にスライド可能なスライド部Ｃと、スライド部Ｃを軸線Ｘに沿って開き位置側から閉じ位置側に向かう上向きに付勢する軸線付勢手段Ｄと、スライド部Ｃのスライドをガイドするガイド部２０とからなる。
操作部１１は、ガス流入路１Ａの軸線Ｘと同軸上に配置されガス栓本体２の上部を覆う逆カップ状の操作ボタン１０の上底部の上面として設けられている。
また、操作ボタン１０は、軸線Ｘに沿って上下方向にスライド可能に設けられており、更に操作ボタン１０の上底部の下面とガス栓本体２の上面との間には、ガス栓本体２に対し操作ボタン１０を上向きに付勢するコイルバネ１３が介挿されている。
尚、このコイルバネ１３は、巻線部分が隣接間において互いに離間している通常のコイルバネが利用されており、軸線Ｘに沿って圧縮力を受けることで同軸線Ｘに沿って膨張力を発生する。 (Operation mechanism)
The operation mechanism unit B transmits a downward pressing operation on the operation unit 11 by the operator to the slide valve G ′ and opens the slide unit C along the axis X along the slide line C, which can slide together with the slide valve G ′. It comprises an axis urging means D that urges upward from the position side toward the closed position side, and a guide portion 20 that guides the slide of the slide portion C.
The operation portion 11 is provided as an upper surface of the upper bottom portion of the reverse cup-shaped operation button 10 that is arranged coaxially with the axis X of the gas inflow passage 1A and covers the upper portion of the gas plug body 2.
The operation button 10 is provided so as to be slidable in the vertical direction along the axis X. Further, the operation button 10 is provided between the lower surface of the upper bottom portion of the operation button 10 and the upper surface of the gas plug body 2. A coil spring 13 for biasing the operation button 10 upward is inserted.
The coil spring 13 is an ordinary coil spring in which winding portions are separated from each other between adjacent ones. When the coil spring 13 receives a compressive force along the axis X, an expansion force is generated along the coaxial line X. .

スライド部Ｃは、軸線Ｘ周りに回転自在に設けられたガイドピン１８と、当該ガイドピン１８を軸線Ｘ周りの方向に付勢する回転付勢手段Ｅとを有して構成されている。
ガイドピン１８は、軸線Ｘと同軸上に配置され当該軸線Ｘに沿ってスライド可能な円柱状の軸部材１７の外表面において、軸部材１７の円形断面の径外方向に向けて突出形成されている。
一方、回転付勢手段Ｅは、操作ボタン１０における上底部の下面に一端部が固定され、上記軸部材１７の上面に他端部が固定されて、ガス流入路１Ａの軸線Ｘと同軸上に配置されたねじりコイルバネ１５で構成されている。
尚、このねじりコイルバネ１５は、巻線部分が隣接間において互いに密着しているコイルバネであり、ある回転方向にねじりモーメントを受けることで当該回転方向とは逆の回転方向（図５における右方向）に反発力を発生する。更に、かかるねじりコイルバネ１５は、巻線部分が隣接間において互いに密着していることで、一端側から受けた操作部１１の軸線Ｘに沿った下方向の押圧力を、他端側の軸部材１７に伝達することができる。
ねじりコイルバネ１５の両端部には、突起部１６が設けられており、突起部１６を含む巻線部分が、操作ボタン１０における上底部の下面に形成された溝部１２、及び軸部材１７の上面に形成された溝部１９に嵌め込まれることで、ねじりコイルバネ１５の両端が操作ボタン１０及び軸部材１７に固定されている。 The slide portion C includes a guide pin 18 that is rotatably provided around the axis X, and a rotation biasing means E that biases the guide pin 18 in a direction around the axis X.
The guide pin 18 is disposed coaxially with the axis X and is formed to protrude outward in the radial direction of the circular cross section of the shaft member 17 on the outer surface of the cylindrical shaft member 17 that can slide along the axis X. Yes.
On the other hand, the rotation urging means E has one end fixed to the lower surface of the upper bottom portion of the operation button 10 and the other end fixed to the upper surface of the shaft member 17 so as to be coaxial with the axis X of the gas inflow passage 1A. The torsion coil spring 15 is arranged.
The torsion coil spring 15 is a coil spring in which winding portions are in close contact with each other between adjacent portions, and receives a torsional moment in a certain rotation direction, thereby rotating in the direction opposite to the rotation direction (right direction in FIG. 5). Generates a repulsive force. Furthermore, the torsion coil spring 15 is configured such that the winding portion is in close contact with each other between adjacent portions, so that the downward pressing force along the axis X of the operation unit 11 received from one end side is applied to the shaft member on the other end side. 17 can be transmitted.
Protrusions 16 are provided at both ends of the torsion coil spring 15, and a winding portion including the protrusions 16 is formed on the groove 12 formed on the lower surface of the upper bottom of the operation button 10 and on the upper surface of the shaft member 17. By fitting into the formed groove portion 19, both ends of the torsion coil spring 15 are fixed to the operation button 10 and the shaft member 17.

軸線付勢手段Ｄは、巻線部分が隣接間において互いに離間している通常のコイルバネ２４からなり、軸線Ｘに沿って圧縮力を受けることで同軸線Ｘに沿って膨張力を発生する。
このコイルバネ２４は、スライド弁Ｇ'の下面と、弁収容部５の下方に設けられた筒状部材Ｈ１の上面との間に軸線Ｘに沿って圧縮状態で介挿されており、筒状部材Ｈ１の上面に対してスライド弁Ｇ'を上向きに付勢する形態で、スライド弁Ｇ'とスライド部Ｃとを軸線Ｘに沿って開き位置側から閉じ位置側に向かう上向きに付勢する。 The axis urging means D is composed of a normal coil spring 24 whose winding portions are separated from each other between adjacent ones, and generates an expansion force along the coaxial line X by receiving a compression force along the axis X.
This coil spring 24 is inserted in a compressed state along the axis X between the lower surface of the slide valve G ′ and the upper surface of the cylindrical member H1 provided below the valve housing portion 5. The slide valve G ′ and the slide portion C are urged upward along the axis X from the open position side toward the closed position side in a form in which the slide valve G ′ is urged upward with respect to the upper surface of H1.

ガイド部２０は、ガイドピン１８が挿入されて当該ガイドピン１８の軸線Ｘ上のスライド及び軸線Ｘ周りの回転を誘導するガイド溝２２を外表面に形成した筒状部材２１で構成されている。
更に、このガイド溝２２には、操作部１１に押圧力を付加してスライド弁Ｇ'を開き位置から閉じ位置まで変位させるときにガイドピン１８をねじりコイルバネ１５の付勢力に抗して回転させる回転誘導部２２ａ、２２ｂと、続いて当該押圧力を抜いたときにスライド弁Ｇ'を閉じ位置に維持する状態でコイルバネ２４及びねじりコイルバネ１５により付勢されるガイドピン１８が係止する係止部２２ｃとが形成されている。
そして、このような構成により、本第２実施形態のガス栓は、詳細については後述するが、操作部１１に対する一の押圧操作により開栓動作が行われ、それに続く操作部１１に対する一の押圧操作により閉栓動作が行われる所謂プッシュプッシュ式の開閉動作を実現している。 The guide portion 20 is configured by a cylindrical member 21 having a guide groove 22 formed on the outer surface for guiding the guide pin 18 to slide on the axis line X and to rotate around the axis line X.
Further, the guide groove 18 is rotated against the urging force of the torsion coil spring 15 when a pressure is applied to the operation portion 11 to displace the slide valve G ′ from the open position to the closed position. Rotation guides 22a and 22b, and a locking mechanism in which the guide pin 18 biased by the coil spring 24 and the torsion coil spring 15 is locked while the slide valve G ′ is maintained in the closed position when the pressing force is subsequently removed. A portion 22c is formed.
With such a configuration, the gas stopper according to the second embodiment will be described in detail later, but the opening operation is performed by one pressing operation on the operation unit 11, and then one pressing operation on the operation unit 11 is performed. A so-called push-push type opening / closing operation in which a plugging operation is performed by an operation is realized.

図１０（ａ）に示すように、このガイド溝２２において、回転誘導部２２ａ、２２ｂの開き位置側の端部が、ねじりコイルバネ１５の軸線Ｘ周りの付勢力に抗する回転方向において係止部２２ｃより回転奥側（例えば図１０（ａ）において左側）に位置する。回転誘導部２２ａ、２２ｂの開き位置側の端部から係止部２２ｃにかけて、ガイド溝２２がコイルバネ２４の軸線Ｘに沿った付勢方向側（即ち上方側）に膨出してなる膨出部２２ｄが形成されている。
よって、ガイドピン１８が、その膨出部２２ｄを介して、回転誘導部２２ａ、２２ｂの開き位置側の端部から係止部２２ｃに向けてガイド溝２２の上辺に沿って直接的に移動可能となり、係止部２２ｃに適切に係止されるようになる。尚、この膨出部２２ｄの形状等は適宜変更可能であり、また、膨出部２２ｄを省略して、開き位置側回転誘導部２２ｂの途中に上方に切れ込む係止部２２ｃを形成し、開き位置側の端部にガイドピン１８がある状態で操作部１１に付加する押圧力ｆ１１を取り除いたときに、ガイドピン１８が開き位置側回転誘導部２２ｂを若干逆行しその途中にある係止部２２ｃに係止されるように構成しても構わない。 As shown in FIG. 10A, in the guide groove 22, the end portions on the opening position side of the rotation guide portions 22 a and 22 b are locking portions in the rotational direction against the urging force around the axis X of the torsion coil spring 15. It is located on the far side of rotation (for example, the left side in FIG. 10A) from 22c. A bulging portion 22d formed by the guide groove 22 bulging in the urging direction side (that is, the upper side) along the axis X of the coil spring 24 from the opening position side end of the rotation guiding portions 22a and 22b to the locking portion 22c. Is formed.
Therefore, the guide pin 18 can move directly along the upper side of the guide groove 22 from the end of the rotation guide portions 22a and 22b toward the locking portion 22c through the bulging portion 22d. Thus, it is appropriately locked to the locking portion 22c. The shape and the like of the bulging portion 22d can be changed as appropriate, and the bulging portion 22d is omitted, and a locking portion 22c that cuts upward is formed in the middle of the opening position side rotation guiding portion 22b. When the pressing force f11 applied to the operation unit 11 is removed with the guide pin 18 at the end on the position side, the guide pin 18 opens, and the locking portion located in the middle of the position side rotation guide portion 22b is slightly reversed. You may comprise so that it may be latched by 22c.

この回転誘導部２２ａ、２２ｂは、軸線Ｘ周りの方向において係止部２２ｃよりも開き位置側に配置された開き位置側回転誘導部２２ｂと係止部２２ｃよりも閉じ位置側に配置された閉じ位置側回転誘導部２２ａとからなる。
更に、ガス流入路１Ａの軸線Ｘの直交面をＳとすると、開き位置側回転誘導部２２ｂにおける直交面Ｓに対するガイド溝２２のリード角αｂが、閉じ位置側回転誘導部２２ａの同リード角αａよりも小さく設定されている。
即ち、開栓動作において、操作部１１に押圧力が付加され回転誘導部２２ａ、２２ｂに沿って誘導されるガイドピン１８は、閉じ位置側から係止部２２ｃが形成された位置までの間は閉じ位置側回転誘導部２２ａに沿って変位し、その係止部２２ｃが形成された位置からそれよりも回転奥側に形成された開き位置側の端部までの間は開き位置側回転誘導部２２ｂに沿って変位することになる。
そして、開き位置側回転誘導部２２ｂのリード角αｂが、閉じ位置側回転誘導部２２ａのリード角αａよりも小さいので、ねじりコイルバネ１５の付勢力に抗してガイドピン１８を開き位置側回転誘導部２２ｂに沿って変位させるために必要な操作部１１に対する押圧力は、閉じ位置側回転誘導部２２ａに沿って変位させるときよりも大きくなる。
以下、ガイド溝２２の詳細構成について、本実施形態のガス栓の開閉動作時におけるガイド溝２２におけるガイドピン１８の遷移状態とあわせて、図１０及び図１１等に基づいて説明する。尚、図１０及び図１１において、ガイド溝２２は、筒状部材２１の外周面を平面に展開したときの状態で示されている。 The rotation guiding portions 22a and 22b are in the direction around the axis X, the opening position side rotation guiding portion 22b disposed on the opening position side with respect to the locking portion 22c and the closing position disposed on the closing position side with respect to the locking portion 22c. It consists of a position side rotation guiding part 22a.
Furthermore, when the orthogonal plane of the axis X of the gas inflow passage 1A is S, the lead angle αb of the guide groove 22 with respect to the orthogonal plane S in the open position side rotation guiding portion 22b is the same lead angle αa of the closed position side rotation guiding portion 22a. Is set smaller than.
That is, in the plug opening operation, the guide pin 18 that is applied with the pressing force to the operation portion 11 and is guided along the rotation guide portions 22a and 22b is between the closed position side and the position where the locking portion 22c is formed. The opening position side rotation guiding portion is displaced along the closed position side rotation guiding portion 22a from the position where the locking portion 22c is formed to the end portion on the opening position side formed on the far side of the rotation. It will be displaced along 22b.
Since the lead angle αb of the opening position side rotation guiding portion 22b is smaller than the lead angle αa of the closing position side rotation guiding portion 22a, the guide pin 18 is opened against the biasing force of the torsion coil spring 15 and the position side rotation guiding is performed. The pressing force with respect to the operation unit 11 necessary for displacing along the portion 22b is larger than when displacing along the closed position side rotation guiding portion 22a.
Hereinafter, the detailed configuration of the guide groove 22 will be described based on FIGS. 10 and 11 together with the transition state of the guide pin 18 in the guide groove 22 during the opening and closing operation of the gas stopper of the present embodiment. 10 and 11, the guide groove 22 is shown in a state where the outer peripheral surface of the cylindrical member 21 is developed on a plane.

〔開栓動作時〕
先ず、本実施形態のガス栓の開栓動作時のガイド溝２２におけるガイドピン１８の位置の遷移状態について、図１０等に基づいて説明する。
スライド弁Ｇ'が閉じ位置にあって閉栓しているとき（図５参照）には、ガイドピン１８は、図１０（ａ）に示すように、ガイド溝２２において回転誘導部２２ａの閉じ位置側の端部（図１０（ａ）において右上端部）に位置している。
次に、操作部１１に押圧力ｆ１１を付加し、その押圧力ｆ１１がスライド部Ｃに伝達されると、スライド部Ｃに設けられたガイドピン１８は、図１０（ｂ）に示すように、ガイド溝２２において閉じ位置側回転誘導部２２ａと開き位置側回転誘導部２２ｂとの境界部に移動する。
この移動の際に、ガイドピン１８は、コイルバネ２４による軸線Ｘに沿った開き位置側から閉じ位置側へ向かう上向きの付勢力ｆｄに抗して閉じ位置側から開き位置側へ向かう下向きに変位すると共に、ねじりコイルバネ１５による軸線Ｘ周りの方向への付勢力ｆｅに抗して回転することになる。
即ち、閉じ位置側回転誘導部２２ａと開き位置側回転誘導部２２ｂとの境界部に位置するガイドピン１８には、図１０（ｂ）において、上向きの付勢力ｆｄと右向きの付勢力ｆｅとが付加された状態となっている。 (When opening)
First, the transition state of the position of the guide pin 18 in the guide groove 22 during the opening operation of the gas stopper according to the present embodiment will be described with reference to FIG.
When the slide valve G ′ is in the closed position and is closed (see FIG. 5), the guide pin 18 is connected to the rotation guide portion 22a at the closed position side of the guide groove 22 as shown in FIG. Is located at the end (upper right end in FIG. 10A).
Next, when a pressing force f11 is applied to the operation portion 11 and the pressing force f11 is transmitted to the slide portion C, the guide pin 18 provided on the slide portion C is as shown in FIG. The guide groove 22 moves to the boundary between the closed position side rotation guiding portion 22a and the open position side rotation guiding portion 22b.
During this movement, the guide pin 18 is displaced downward from the closed position side to the open position side against the upward biasing force fd from the open position side along the axis X by the coil spring 24 toward the closed position side. At the same time, the torsion coil spring 15 rotates against the urging force fe in the direction around the axis X.
That is, the upward biasing force fd and the rightward biasing force fe in FIG. 10B are applied to the guide pin 18 located at the boundary between the closed position side rotation guiding portion 22a and the open position side rotation guiding portion 22b. It has been added.

更に、操作部１１に比較的大きい押圧力ｆ１１を付加すると、ガイドピン１８は、図１０（ｃ）に示すように、ガイド溝２２において開き位置側回転誘導部２２ｂの回転奥側（図１０（ｃ）の左側）の端部に移動し、それに伴ってスライド弁Ｇ'は開き位置（図８参照）に変位する。
この移動の際においても、ガイドピン１８は、コイルバネ２４による上向きの付勢力ｆｄとねじりコイルバネ１５による右向きの付勢力ｆｅに抗して左下方向に移動することになり、移動後のガイドピン１８には、上向きの付勢力ｆｄと右向きの付勢力ｆｅとが付加された状態となっている。
尚、これら付勢力ｆｄ、ｆｅは、ガイドピン１８の左下方向への変位量が増加するに伴って増加するが、説明を簡単にするためにそれらの符号は同じものを使用する。 Further, when a relatively large pressing force f11 is applied to the operation portion 11, the guide pin 18 is moved to the back side of the opening position side rotation guiding portion 22b in the guide groove 22 as shown in FIG. c), the slide valve G ′ is displaced to the open position (see FIG. 8).
Also in this movement, the guide pin 18 moves in the lower left direction against the upward biasing force fd by the coil spring 24 and the rightward biasing force fe by the torsion coil spring 15, and the guide pin 18 after the movement Is a state in which an upward biasing force fd and a rightward biasing force fe are added.
The urging forces fd and fe increase as the amount of displacement of the guide pin 18 in the lower left direction increases, but the same reference numerals are used to simplify the explanation.

次に、上記のように操作部１１に対して付加していた押圧力ｆ１１を取り除くと、図１０（ｄ）に示すように、コイルバネ２４による上向きの付勢力ｆｄとねじりコイルバネ１５による右向きの付勢力ｆｅによって、ガイドピン１８は、膨出部２２ｄに沿って右上方向にある係止部２２ｃに当接する位置まで移動する。
そして、係止部２２ｃのガイドピン１８が当接する壁面の角度が、付勢力ｆｄ、ｆｅの合力が付加されているガイドピン１８が回転誘導部２２ａ、２２ｂ側に変位することを防止する角度に設定されているので、当該ガイドピン１８の位置は係止部２２ｃに係止された状態で保たれることになり、結果、図９に示すように、スライド弁Ｇ'が開き位置で維持されて、開栓動作が完了する。 Next, when the pressing force f11 applied to the operation unit 11 is removed as described above, an upward biasing force fd by the coil spring 24 and a rightward application by the torsion coil spring 15 are obtained as shown in FIG. Due to the force fe, the guide pin 18 moves along the bulging portion 22d to a position where it abuts on the locking portion 22c in the upper right direction.
The angle of the wall surface with which the guide pin 18 of the locking portion 22c abuts is such that the guide pin 18 to which the resultant force of the urging forces fd and fe is applied is prevented from being displaced toward the rotation guide portions 22a and 22b. Since it is set, the position of the guide pin 18 is maintained in a state of being locked to the locking portion 22c. As a result, as shown in FIG. 9, the slide valve G ′ is maintained in the open position. Thus, the opening operation is completed.

〔閉栓動作時〕
次に、本実施形態のガス栓の閉栓動作時のガイド溝２２におけるガイドピン１８の位置の遷移状態について、図１１等に基づいて説明する。
スライド弁Ｇ'が開き位置にあって開栓しているとき（図９参照）には、ガイドピン１８は、図１１（ａ）に示すように、係止部２２ｃに係止される位置にある。
次に、操作部１１に比較的小さな押圧力ｆ１１'を付加し、その押圧力ｆ１１'がスライド部Ｃに伝達されると、スライド部Ｃに設けられたガイドピン１８は、図１１（ｂ）に示すように、付勢力ｆｄ、ｆｅに抗して左下向きに若干変位することで、係止部２２ｃにおける係止が解除された位置に変位する。
この際に、操作部１１に付加される押圧力ｆ１１'は、上述した開栓動作時に付加した押圧力ｆ１１よりも小さなものとなっているため、ガイドピン１８は、例えば開き位置側回転誘導部２２ｂに沿って開き位置側に変位することはない。
更に、開き位置側回転誘導部２２ｂのリード角αｂが閉じ位置側回転誘導部２２ａのリード角αａよりも小さく、ねじりコイルバネ１５の付勢力ｆｅに抗してガイドピン１８を開き位置側回転誘導部２２ｂに沿って開き位置側へ変位させるためには比較的大きな押圧力が必要となるので、その押圧力よりも小さな押圧力ｆ１１'で操作部１１を押圧した場合には、ガイドピン１８が開き位置側回転誘導部２２ｂに沿って回転奥側に変位することはない。 [When closing operation]
Next, the transition state of the position of the guide pin 18 in the guide groove 22 during the gas stopper closing operation of the present embodiment will be described with reference to FIG.
When the slide valve G ′ is in the open position and is open (see FIG. 9), the guide pin 18 is in a position to be locked to the locking portion 22c as shown in FIG. 11 (a). is there.
Next, when a relatively small pressing force f11 ′ is applied to the operation portion 11 and the pressing force f11 ′ is transmitted to the slide portion C, the guide pin 18 provided on the slide portion C is moved to the position shown in FIG. As shown in FIG. 2, the lever is slightly displaced in the lower left direction against the urging forces fd and fe, so that the latching portion 22c is unlocked.
At this time, since the pressing force f11 ′ applied to the operation unit 11 is smaller than the pressing force f11 applied during the above-described opening operation, the guide pin 18 is, for example, an opening position side rotation guiding unit. There is no displacement toward the open position along 22b.
Further, the lead angle αb of the opening position side rotation guiding portion 22b is smaller than the lead angle αa of the closing position side rotation guiding portion 22a, and the guide pin 18 is opened against the biasing force fe of the torsion coil spring 15 to open the position side rotation guiding portion. Since a relatively large pressing force is required for displacing along the opening position 22b, the guide pin 18 opens when the operating portion 11 is pressed with a pressing force f11 'smaller than the pressing force. There is no displacement toward the back of the rotation along the position side rotation guiding portion 22b.

次に、上記のように操作部１１に対し付加されていた押圧力ｆ１１'を取り除くと、図１１（ｃ）に示すように、コイルバネ２４による上向きの付勢力ｆｄとねじりコイルバネ１５による右向きの付勢力ｆｅによって、ガイドピン１８は、閉じ位置側回転誘導部２２ａに沿って右上方向に移動し、結果、図５に示すように、それに伴ってスライド弁Ｇ'が開き位置から閉じ位置まで変位して、閉栓動作が完了する。
尚、本実施形態では、ガイド溝２２の回転誘導部を閉じ位置側回転誘導部２２ａと開き位置側回転誘導部２２ｂとで構成したが、当該回転誘導部を一様のもので構成しても構わない。また、回転誘導部２２ａ、２２ｂのリード角αａ、αｂについては、一様のものとせずに、例えば閉じ位置側から開き位置側にかけて徐々に減少させるなど、適宜改変可能である。 Next, when the pressing force f11 ′ applied to the operation unit 11 as described above is removed, an upward biasing force fd by the coil spring 24 and a rightward application by the torsion coil spring 15 are removed as shown in FIG. Due to the force fe, the guide pin 18 moves in the upper right direction along the closed position side rotation guiding portion 22a, and as a result, as shown in FIG. 5, the slide valve G ′ is displaced from the open position to the closed position. Thus, the closing operation is completed.
In the present embodiment, the rotation guide portion of the guide groove 22 is configured by the closed position side rotation guide portion 22a and the open position side rotation guide portion 22b, but the rotation guide portion may be configured by a uniform one. I do not care. Further, the lead angles αa and αb of the rotation guiding portions 22a and 22b are not uniform and can be appropriately modified, for example, gradually decreasing from the closed position side to the open position side.

〔リセット手段〕
本実施形態のガス栓は、一定以上の流量のガスｇが流れると当該ガス供給を遮断するために、図５に示すように、特定ガス流通路としてのガス流入路１Ａに過流出防止機構Ｈが設けられると共に、当該過流出防止機構Ｈが作動状態となった場合にそれをリセットするリセット手段Ｒが設けられている。

図９に示すように、操作機構部Ｂの操作部１１が押圧操作され、スライド弁Ｇ’が開き位置に位置し、過流出防止弁収容部材Ｈａが上流側に位置し、***作部材Ｈ３が固定部材Ｒ１から離間している状態で、一定以上の流量のガスｇが流れると、過流出防止弁Ｈ２が作動して、過流出を防止する。
ここで、再度、操作機構部Ｂの操作部１１が押圧操作されると、スライド弁Ｇ’が開き位置から閉じ位置へと移動（図９から図５への移動）すると共に、スライド弁Ｇ’と連結部材Ｒ２にて連結された過流出防止弁収容部材Ｈａが下流側に移動して、***作部材Ｈ３が操作位置に固定されている固定部材Ｒ１に当接し、リセット操作が行われる。 [Reset means]

Here, when the operation portion 11 of the operation mechanism portion B is pressed again, the slide valve G ′ moves from the open position to the closed position (movement from FIG. 9 to FIG. 5), and the slide valve G ′. The overflow prevention valve housing member Ha connected by the connecting member R2 moves downstream, and the operated member H3 comes into contact with the fixed member R1 fixed at the operation position, and the reset operation is performed.
