Description

本発明は、ガス機器に接続された第１管状部材とガス供給源に接続された第２管状部材とを接続するための管接続具に関する。 The present invention relates to a pipe connector for connecting a first tubular member connected to a gas device and a second tubular member connected to a gas supply source.

例えば、ガスボンベ（又は埋設ガス管）からの燃料用ガスをガス機器としてのガスコンロに供給するために、ガスボンベ（又は埋設ガス管）からのガス配管とガスコンロのコンロ側接続部とを接続するためのガス栓付管継手を用いた配管構造が開示されている（例えば、特許文献１参照）。この配管構造においては、ガスコンロの側壁の一部に管継手用凹入部及びガス管用凹入部が設けられ、管継手用凹入部にガス栓付管継手が収容され、また配管用凹入部にガス配管の一部が収容される。ガスコンロは、例えばシステムキッチンのキッチンカウンタの上部空間に収納装着され、ガス配管の一部及びガス栓付管継手をこのようにガスコンロの管継手用凹入部及び配管用凹入部に収容することによって、キッチンカウンタの下側の空間（通常、このキッチンカウンタの下側は、調理用具などを収納する収納空間が設けられる）にガス配管の一部、ガス栓付管継手などが突出することがなく、この収納空間を広く利用することが可能となる。 For example, to supply fuel gas from a gas cylinder (or buried gas pipe) to a gas stove as a gas appliance, for connecting a gas pipe from the gas cylinder (or buried gas pipe) and a stove side connecting portion of the gas stove A piping structure using a pipe joint with a gas stopper is disclosed (for example, see Patent Document 1). In this piping structure, a recessed portion for a pipe joint and a recessed portion for a gas pipe are provided in a part of the side wall of the gas stove, and the fitting with a gas stopper is accommodated in the recessed portion for the pipe joint, and the gas pipe is disposed in the recessed portion for the pipe. Part of it is housed. The gas stove is housed and installed in the upper space of the kitchen counter of the system kitchen, for example, and by accommodating a part of the gas pipe and the pipe fitting with a gas stopper in this way in the recessed part for the pipe joint and the recessed part for the pipe, A part of the gas piping, a fitting with a gas stopper, etc. do not protrude into the space below the kitchen counter (usually the storage space for storing cooking utensils is provided under the kitchen counter) This storage space can be widely used.

しかしながら、ガスコンロをこのように構成するには、従来のガスコンロと構造が大きく異なっており、それ故に、ガスコンロ自体を新たに開発する必要があり、製造コストが高くなるなどの問題がある。 However, in order to configure the gas stove in this way, the structure is greatly different from that of the conventional gas stove. Therefore, it is necessary to newly develop the gas stove itself, and there is a problem that the manufacturing cost increases.

このようなことから、通常のガスコンロを用いる場合、ガスボンベ（又はガス埋設管）からのガス配管は、例えば、図１１に示すような配管構造によってガスコンロに接続される。図１１（ａ）において、システムキッチン２のキッチンカウンタ４の上部には上部空間が設けられ、この上部空間にガスコンロ６（ビルトイン型のもの）が収容装着される。キッチンカウンタ４の下部には収納空間８が設けられ、この収納空間８は、例えば仕切り部材１０によって、上側の上収納空間１２と下側の下収納空間１４とに仕切られている。収納空間８の開口部には一対の開閉扉１６が開閉自在に設けられている。 For this reason, when a normal gas stove is used, the gas pipe from the gas cylinder (or gas buried pipe) is connected to the gas stove by a pipe structure as shown in FIG. 11, for example. In FIG. 11A, an upper space is provided above the kitchen counter 4 of the system kitchen 2, and a gas stove 6 (built-in type) is accommodated and mounted in this upper space. A storage space 8 is provided below the kitchen counter 4, and the storage space 8 is partitioned into an upper storage space 12 on the upper side and a lower storage space 14 on the lower side by a partition member 10, for example. A pair of opening / closing doors 16 is provided at the opening of the storage space 8 so as to be freely opened and closed.

ガスボンベなどからのガス配管１８は、キッチンカウンタ４の収納空間８（具体的には、上収納空間１２）内を手前側に延びるように配設される。一方、ガスコンロ６のコンロ側接続部２２は、キッチンカウンタ４の化粧支持板２０の開口を通して収納空間８（上収納空間１２）内に突出する。このガス配管１８とコンロ側接続部２２を接続する場合、図１１（ｂ）で示すように、コンロ側接続部２２に位置調整接続部材２４を接続する。次いで、図１１（ｃ）で示すように、ガス栓付管継手２６の第１接続部２８を位置調整接続部材２４に接続し、その後、このガス栓付管継手２６の第２接続部３０にガス配管１８を接続し、このようにしてガス配管１８とコンロ側接続部２２とが位置調整接続部材２４及びガス栓付管継手２６を介して接続される。 A gas pipe 18 from a gas cylinder or the like is disposed so as to extend forward in the storage space 8 (specifically, the upper storage space 12) of the kitchen counter 4. On the other hand, the stove side connection portion 22 of the gas stove 6 protrudes into the storage space 8 (upper storage space 12) through the opening of the decorative support plate 20 of the kitchen counter 4. When connecting the gas pipe 18 and the stove side connecting portion 22, as shown in FIG. 11B, the position adjustment connecting member 24 is connected to the stove side connecting portion 22. Next, as shown in FIG. 11 (c), the first connection portion 28 of the gas plug-attached pipe joint 26 is connected to the position adjusting connection member 24, and thereafter, the second connection portion 30 of the gas plug-attached pipe joint 26 is connected to the second connection portion 30. The gas pipe 18 is connected, and the gas pipe 18 and the stove side connection portion 22 are thus connected via the position adjusting connection member 24 and the gas plug-attached pipe joint 26.

Note that the outer peripheral shape of the other end portion is formed in, for example, a hexagonal shape corresponding to the shape of the tightening tool so that the tightening member 78 described later can be easily tightened. Shape may be sufficient.

また、補助スリーブ７９は、スリーブ状部材から構成され、接続管部材６０の環状収容突部８４の外周側に対し、軸線方向（図１及び図２において上下方向）に移動自在に且つこの接続管部材６０と一体的に回動するように、装着されている。接続管部材６０の環状収容突部８４と補助スリーブ７９との間には係合手段１０１が介在され、この実施形態では、係合手段１０１は一対の係合リング１０３から構成され、かかる一対の係合リング１０３が環状収容突部８４の両端部に装着され、かかる一対の係合リング１０３に対応して、補助スリーブ７９の両端部内周面に係合凹部１０５が設けられ、これら係合リング１０３は係合凹部１０５に係脱自在に係合される。従って、この補助スリーブ７９は、一対の係合リング１０３が一対の係合凹部１０５に係合する第１の位置（図１、図５及び図６に示す位置）と、接続管部材６０の他端側の係合リング１０３と補助スリーブ７９の一端側の係合凹部１０５とが係合する第２の位置（図２〜図４に示す位置）との間を上記軸線方向に移動自在である。第１の位置にあるときには、補助スリーブ７９は接続管部材６０の他端側に位置してこれから外側に突出することはないが、第２の位置にあるときには、補助スリーブ７９の他端側は接続管部材６０の他端から上記軸線方向外方に突出し、このように突出させることによって、接続管部材６０を回動させることができる部位を上記軸線方向に長くすることができる。 The auxiliary sleeve 79 is formed of a sleeve-like member, and is movable in the axial direction (vertical direction in FIGS. 1 and 2) with respect to the outer peripheral side of the annular housing protrusion 84 of the connection pipe member 60 and the connection pipe. It is mounted so as to rotate integrally with the member 60. An engaging means 101 is interposed between the annular housing projection 84 of the connecting pipe member 60 and the auxiliary sleeve 79. In this embodiment, the engaging means 101 is composed of a pair of engaging rings 103, and the pair of engaging rings 101 is provided. Engagement rings 103 are attached to both ends of the annular housing projection 84, and corresponding recesses 105 are provided on the inner peripheral surfaces of both ends of the auxiliary sleeve 79 corresponding to the pair of engagement rings 103. 103 is detachably engaged with the engagement recess 105. Accordingly, the auxiliary sleeve 79 has a first position where the pair of engagement rings 103 engage with the pair of engagement recesses 105 (the position shown in FIGS. 1, 5, and 6), and the connection pipe member 60. It is movable in the axial direction between a second position (position shown in FIGS. 2 to 4) where the engagement ring 103 on the end side and the engagement recess 105 on the one end side of the auxiliary sleeve 79 are engaged. . When in the first position, the auxiliary sleeve 79 is located on the other end side of the connecting pipe member 60 and does not protrude outwardly. However, when in the second position, the other end side of the auxiliary sleeve 79 is By projecting outward in the axial direction from the other end of the connecting pipe member 60 and projecting in this manner, a portion where the connecting pipe member 60 can be rotated can be lengthened in the axial direction.

この補助スリーブ７９に関し、後述する締込み方向及び離脱方向の回動が容易となるように、その外周面形状は、締込み工具の形状に対応した例えば六角形状に形成されるが、八角形状などの適宜の形状に形成することができる。また、このことに関連して、補助スリーブ７９の内周形状も例えば六角形状に形成され、このことに対応して、接続管部材６０の環状収容突部８４の外周形状も六角形状に形成される（図１参照）が、これらの形状についても八角形状などの適宜の形状でよく、或いは軸線方向に延びるスプラインを設けるようにしてもよい。 Regarding the auxiliary sleeve 79, the outer peripheral surface shape thereof is formed in, for example, a hexagonal shape corresponding to the shape of the tightening tool so as to facilitate the rotation in the tightening direction and the disengagement direction described later. It can be formed in an appropriate shape. In relation to this, the inner peripheral shape of the auxiliary sleeve 79 is also formed, for example, in a hexagonal shape, and the outer peripheral shape of the annular accommodating projection 84 of the connecting pipe member 60 is also formed in a hexagonal shape correspondingly. However, these shapes may also be appropriate shapes such as octagonal shapes, or splines that extend in the axial direction may be provided.

また、この形態では、一対の係合リング１０３を環状収容突部８４の両端部に装着しているが、これとは反対に、これら係合リング１０３を補助スリーブ７９の両端部内周面に装着するようにしてもよく、かかる場合、係合リング１０３に対応する係合凹部１０５は接続管部材６０の環状収容突部８４の外周面に設けられる。 In this embodiment, a pair of engagement rings 103 are attached to both ends of the annular housing projection 84, but on the contrary, these engagement rings 103 are attached to the inner peripheral surfaces of both ends of the auxiliary sleeve 79. In such a case, the engagement recess 105 corresponding to the engagement ring 103 is provided on the outer peripheral surface of the annular housing protrusion 84 of the connection pipe member 60.

このような管接続具５２は、弁ハウジング本体５４の第１接続部５６側がガスコンロ６２に接続され、その第２接続部５８がガス供給源側のガス配管６６に接続される。ガスコンロ６２の底部にはコンロ側接続部６４（第１管状部材）が設けられ、このコンロ側接続部６４の内周面に雌ねじ部１０２が設けられており、接続管部材６０の雄ねじ部８２は、後述する如くしてコンロ側接続部６４の雌ねじ部１０２に螺着される。 In such a pipe connector 52, the first connecting portion 56 side of the valve housing main body 54 is connected to the gas stove 62, and the second connecting portion 58 is connected to the gas pipe 66 on the gas supply source side. A stove-side connecting portion 64 (first tubular member) is provided at the bottom of the gas stove 62, and an internal thread portion 102 is provided on the inner peripheral surface of the stove-side connecting portion 64. As will be described later, it is screwed into the female threaded portion 102 of the stove side connecting portion 64.

また、弁ハウジング本体５４の第２接続部５８の内周面に雌ねじ部１０６が設けられ、ガス供給源としてのガスボンベ（図示せず）などに接続されたガス配管６６（第２管状部材）の先端部には雄ねじ部１０４が設けられ、このガス配管６６の雄ねじ部１０４が第２接続部５８の雌ねじ部１０６に後述する如くして螺着される。 Further, a female screw portion 106 is provided on the inner peripheral surface of the second connection portion 58 of the valve housing main body 54, and a gas pipe 66 (second tubular member) connected to a gas cylinder (not shown) as a gas supply source or the like. A male screw portion 104 is provided at the tip, and the male screw portion 104 of the gas pipe 66 is screwed to the female screw portion 106 of the second connection portion 58 as described later.

次に、図２とともに図３〜図６を参照して、上述した管接続具５２を用いた管の接続作業について説明する。図３を参照して、例えばキッチンカウンタには上部空間１１０が設けられ、この上部空間１１０にガスコンロ６２が載置収容され、このように載置された状態では、ガスコンロ６２の支持脚部１１２（図３において一つのみ示す）は、キッチンカウンタの化粧支持板１１４に載置される。 Next, with reference to FIG. 3 and FIG. 6 together with FIG. 2, a pipe connection operation using the pipe connector 52 described above will be described. Referring to FIG. 3, for example, the kitchen counter is provided with an upper space 110, and the gas stove 62 is placed and accommodated in the upper space 110, and in such a state, the support legs 112 ( (Only one is shown in FIG. 3) is placed on the decorative support plate 114 of the kitchen counter.

このようにキッチンカウンタに取り付けたガスコンロ６２のコンロ側接続部６４（第１管状部材）とガス供給源側のガス配管６６（第２管状部材）とを接続するには、先ず、図４に示すように、管接続具５２の接続管部材６０をコンロ側接続部６４に接続する。この接続の際には、補助スリーブ７９を第２の位置に位置付けてその端部を接続管部材６０から軸線方向外方に突出させ、この状態にて接続管部材６０の先端側の雄ねじ部８２を化粧支持板１１４の接続開口１１６を通してコンロ側接続部６４の雌ねじ部１０２に螺合させ、補助スリーブ７９に取付工具（図示せず）を係合させて締付け方向に回動すればよく、このように回動すると、補助スリーブ７９と一体的に接続管部材６０が締付け方向に回動され、その雄ねじ部８２がコンロ側接続部６４の雌ねじ部１０２に螺着され、このようにして接続管部材６０がガスコンロ６２に着脱可能に接続される。このとき、接続管部材６０に対して弁ハウジング本体５４が相対的に回動自在であるので、この弁ハウジング本体５４が回動することはない。尚、化粧支持板１１４からの接続管部材６０（環状収容突部８４）の突出量が大きいときには、補助スリーブ７９を第１の位置に位置付けたままこの補助スリーブ７９を締付け方向に回動することができる。 To connect the stove side connecting portion 64 (first tubular member) of the gas stove 62 attached to the kitchen counter in this way and the gas pipe 66 (second tubular member) on the gas supply source side, first, as shown in FIG. As described above, the connecting pipe member 60 of the pipe connector 52 is connected to the stove side connecting portion 64. At the time of this connection, the auxiliary sleeve 79 is positioned at the second position, and its end protrudes outward in the axial direction from the connection pipe member 60. In this state, the male thread 82 on the distal end side of the connection pipe member 60 is provided. Is screwed into the female threaded portion 102 of the stove-side connecting portion 64 through the connection opening 116 of the decorative support plate 114, and an attachment tool (not shown) is engaged with the auxiliary sleeve 79 and rotated in the tightening direction. Thus, the connecting tube member 60 is rotated integrally with the auxiliary sleeve 79 in the tightening direction, and the male screw portion 82 is screwed to the female screw portion 102 of the stove side connecting portion 64, and thus the connecting tube. The member 60 is detachably connected to the gas stove 62. At this time, since the valve housing main body 54 is rotatable relative to the connecting pipe member 60, the valve housing main body 54 does not rotate. When the protruding amount of the connecting tube member 60 (annular housing projection 84) from the decorative support plate 114 is large, the auxiliary sleeve 79 is rotated in the tightening direction while the auxiliary sleeve 79 is positioned at the first position. Can do.

次いで、図５に示すように、補助スリーブ７９を軸線方向にガスコンロ６２側に移動させて第１の位置に位置付けるとともに、弁ハウジング本体５４の第２接続部５８にガス配管６６を接続する。このガス配管６６の接続は、第２接続部５８の雌ねじ部１０６にガス配管６６の雄ねじ部１０４を螺合し、ガス配管６６を締付け方向に回動させればよく、このようにしてガス配管６６が弁ハウジング本体５４に着脱自在に接続される。 Next, as shown in FIG. 5, the auxiliary sleeve 79 is moved to the gas stove 62 side in the axial direction and positioned at the first position, and the gas pipe 66 is connected to the second connection portion 58 of the valve housing body 54. The gas pipe 66 may be connected by screwing the male screw part 104 of the gas pipe 66 to the female screw part 106 of the second connecting part 58 and rotating the gas pipe 66 in the tightening direction. 66 is detachably connected to the valve housing body 54.

その後、図６に示すように、締込み部材７８を締め込んで弁ハウジング本体５４を上方にガスコンロ６２側に移動させる。この締込みは、締込み部材７８の下端部の六角形状部に締込み工具（図示せず）を係合させて締付け方向に回動すればよく、このように回動すると、接続管部材６０の雌ねじ部９０と締込み部材７８側の雄ねじ部９６によって、この締込み部材７８が上方にガスコンロ６２側に移動してその一端側が接続管部材６０の環状収容凹部８８に収容されるとともに、締込み部材７８の上方移動とともに連結リング１００を介して弁ハウジング本体５４がガスコンロ６２側に移動され、例えば締込み部材７８の一端（即ち、上端）が接続管部材６０の環状収容凹部８８の底面に当接するまで（又は締込み部材７８の他端部が接続管部材６０の環状収容突部８４の先端面に当接するまで）締め込まれ、このようにしてガス配管６６が管接続具５２を介してガスコンロ６２に接続される。 Thereafter, as shown in FIG. 6, the tightening member 78 is tightened to move the valve housing main body 54 upward to the gas stove 62 side. The tightening may be performed by engaging a tightening tool (not shown) with the hexagonal portion at the lower end of the tightening member 78 and rotating in the tightening direction. The internal thread portion 90 and the external thread portion 96 on the tightening member 78 side cause the tightening member 78 to move upward toward the gas stove 62 so that one end of the tightening member 78 is accommodated in the annular accommodating recess 88 of the connecting pipe member 60 and tightened. The valve housing main body 54 is moved to the gas stove 62 side through the connecting ring 100 along with the upward movement of the fitting member 78, and for example, one end (that is, the upper end) of the fastening member 78 is placed on the bottom surface of the annular housing recess 88 of the connecting pipe member 60. It is tightened until it abuts (or until the other end portion of the tightening member 78 abuts on the front end surface of the annular accommodating projection 84 of the connection pipe member 60), and the gas pipe 66 is thus interposed via the pipe connector 52. It is connected to the gas stove 62.

このような接続状態では、締込み部材７８が軸線方向にコンロ側接続部６４（即ち、ガスコンロ６２）側に移動し、その一端部（図６において上部）が接続管部材６０の環状収容凹部８８に収容された状態で化粧支持板１１４の接続開口１１６及びその上方に位置し、これによって弁ハウジング本体５４もコンロ側接続部６４側に移動するので、図５と図６とを比較することによって容易に理解されるように、弁ハウジング本体５４のキッチンカウンタの収納空間１１８への突出量が小さく抑えられ、この収納空間１１８の占有スペースを小さくすることができる。このような接続状態においては、従来に比して管接続具５２がキッチンカウンタの収納空間１１８の上部に収容されるので、ガス配管６６も収納空間１１８のより上部に位置するようになり、これによって、管接続具５２及びガス配管６６が占める空間を小さく抑えることができる。 In such a connection state, the tightening member 78 moves in the axial direction toward the stove side connecting portion 64 (that is, the gas stove 62), and one end portion (upper portion in FIG. 6) of the annular housing recess 88 of the connecting tube member 60. Since the valve housing main body 54 is also moved to the stove side connecting portion 64 side by being located above the connection opening 116 of the decorative support plate 114 in the state of being accommodated in FIG. 5 and FIG. As can be easily understood, the amount of protrusion of the valve housing body 54 into the storage space 118 of the kitchen counter can be kept small, and the occupied space of the storage space 118 can be reduced. In such a connection state, the pipe connector 52 is accommodated in the upper part of the storage space 118 of the kitchen counter as compared with the conventional case, so that the gas pipe 66 is also located in the upper part of the storage space 118. Thus, the space occupied by the pipe connector 52 and the gas pipe 66 can be kept small.

ガスコンロ６２のコンロ側接続部６４から管接続具５２を取り外すには、図６に一点鎖線で示すように、化粧支持板１１の接続開口１１６を通して補助スリーブ７９を軸線方向外方（図６において下方）に引き出して第２の位置に位置付けた後に補助スリーブ７９を離脱方向（緩み方向）に回動すればよい。補助スリーブ７９を第２の位置に位置付けると、補助スリーブ７９の端部（図６において下端部）が化粧支持板１１４から突出し、このような状態においては、補助スリーブ７９の突出部に取外し工具（図示せず）を容易に係合させることができる。そして、この補助スリーブ７９を取外し工具でもって緩み方向に回動させると、これと一体的に接続管部材６０も緩み方向に回動し、弁ハウジング本体５４にガス配管６６が接続された状態でもって、弁ハウジング５４、接続管部材６０及び締込み部材７８をガスコンロ６２のコンロ側接続部６４から着脱自在に取り外すことができる。尚、補助スリーブ７９の化粧支持板１１からの突出量が大きいときには、補助スリーブ７９を第１の位置に保持したまま取外し工具を係合させて取り外すことができる。 In order to remove the pipe connector 52 from the stove side connecting portion 64 of the gas stove 62, the auxiliary sleeve 79 is moved axially outward (downward in FIG. 6) through the connection opening 116 of the decorative support plate 11, as shown by a one-dot chain line in FIG. ) And the auxiliary sleeve 79 may be rotated in the detaching direction (loosening direction) after being positioned at the second position. When the auxiliary sleeve 79 is positioned at the second position, the end of the auxiliary sleeve 79 (the lower end in FIG. 6) protrudes from the decorative support plate 114. In such a state, the removal tool ( (Not shown) can be easily engaged. When the auxiliary sleeve 79 is removed and rotated with a tool in the loosening direction, the connecting pipe member 60 is also rotated integrally with the auxiliary sleeve 79 and the gas pipe 66 is connected to the valve housing main body 54. Accordingly, the valve housing 54, the connecting pipe member 60, and the tightening member 78 can be detachably detached from the stove side connecting portion 64 of the gas stove 62. When the amount of protrusion of the auxiliary sleeve 79 from the decorative support plate 11 is large, the auxiliary sleeve 79 can be detached by engaging the removal tool while holding the auxiliary sleeve 79 in the first position.

そして、かく螺着した後、補助スリーブ７９Ａをガスコンロ側に移動させて第１の位置に位置付けるとともに、弁ハウジング本体５４Ａの第２接続部５８にガス配管の雄ねじ部（図示せず）を螺着し、その後、弁ハウジング本体５４Ａをガスコンロ側に上方に押し上げる。かくすると、ガスコンロに接続された接続管部材６０Ａに対して弁ハウジング本体５４Ａが相対的に上方に移動され、接続管部材６０Ａ側の係合突部１２２が、例えば、最先端側の特定受け凹部１２４ａに係合した状態（図７参照）から最基部側の受け凹部１２４ｄ（図８参照）に着脱自在に係合した状態となるように移動する。このように、この第２の実施形態の管接続具５２Ａを用いた場合にも、上述したと略同様してガス配管を管接続具５２Ａを介してガスコンロに接続することができ、第１の実施形態と同様の作用効果を達成することができる。 Then, after screwing, the auxiliary sleeve 79A is moved to the gas stove side to be positioned at the first position, and a male pipe portion (not shown) of the gas pipe is screwed to the second connection portion 58 of the valve housing body 54A. Thereafter, the valve housing main body 54A is pushed upward to the gas stove side. Thus, the valve housing body 54A is moved relatively upward with respect to the connection pipe member 60A connected to the gas stove, and the engagement protrusion 122 on the connection pipe member 60A side is, for example, the specific receiving recess on the most distal side. It moves from the state engaged with 124a (see FIG. 7) to the state where it is detachably engaged with the receiving recess 124d (see FIG. 8) on the most base side. As described above, even when the pipe connector 52A of the second embodiment is used, the gas pipe can be connected to the gas stove via the pipe connector 52A in substantially the same manner as described above. The same effect as the embodiment can be achieved.

ガスコンロから管接続具５２Ａを取り外すには、弁ハウジング本体５４Ａを下方（ガスコンロから離隔する方向）に引き下げ、かく引き下げた状態にて補助スリーブ７９Ａを第２の位置に位置付け、このような状態にて、補助スリーブ７９Ａを離脱方向（緩み方向）に回動すればよい。弁ハウジング本体５４Ａを下方に引き下げると、補助スリーブ７９Ａの第２の位置への移動が許容され、この補助スリーブ７９Ａを第２の位置に位置付けた後に離脱方向に回動すると、補助スリーブ７９Ａと一体的に接続管部材６０Ａが離脱方向に回動され、このようにして、弁ハウジング本体５４Ａにガス配管が接続された状態でもって、ガスコンロから管接続具５２Ａの接続管部材６０Ａを着脱自在に取り外すことができる。 To remove the pipe connector 52A from the gas stove, the valve housing main body 54A is pulled down (in the direction away from the gas stove), and the auxiliary sleeve 79A is positioned at the second position in such a state. The auxiliary sleeve 79A may be rotated in the detaching direction (loosening direction). When the valve housing main body 54A is pulled down, the auxiliary sleeve 79A is allowed to move to the second position. When the auxiliary sleeve 79A is positioned at the second position and then rotated in the disengagement direction, the auxiliary sleeve 79A is integrated with the auxiliary sleeve 79A. Thus, the connecting pipe member 60A is rotated in the disengagement direction, and the connecting pipe member 60A of the pipe connector 52A is detachably removed from the gas stove with the gas pipe connected to the valve housing main body 54A. be able to.

尚、第２の実施形態では、接続管部材６０Ａに係合突部１２２を設け、第１接続部５６Ａに複数の受け凹部１２４ａ〜１２４ｄを設けているが、これとは反対に、係合突部１２２を第１接続部５６Ａに、複数の受け凹部１２４ａ〜１２４ｄを接続管部材６０Ａに設けるようにしてもよい。また、受け凹部１２４の個数については、適宜設定することができる。 In the second embodiment, the engaging projection 122 is provided on the connecting pipe member 60A, and the plurality of receiving recesses 124a to 124d are provided on the first connecting portion 56A. The portion 122 may be provided in the first connection portion 56A, and the plurality of receiving recesses 124a to 124d may be provided in the connection pipe member 60A. The number of receiving recesses 124 can be set as appropriate.

この実施形態では、補助スリーブ７９Ｂの六角形状の内周面には軸線方向に間隔をおいて複数（この具体例では、三つ）の係合リング１５４ａ，１５４ｂ，１５４ｃが装着され、これら係合リング１５４ａ，１５４ｂ，１５４ｃが係合手段を構成する。係合リング１５４ａ，１５４ｂ，１５４ｃは、補助スリーブ７９Ｂの内周面形状に対応して例えば六角形状に形成される。また、接続管部材６０Ｂのスリーブ状本体８０Ｂの外周面には径方向外方に突出する六角形状の小突部１５６が設けられている。このように構成されているので、補助スリーブ７９Ｂは、接続管部材６０Ｂの環状収容凹部８８に収容される第１の位置（図１０に示す位置）と接続管部材６０Ｂの他端から軸線方向外方に突出する第２の位置（図９に示す位置）との間を軸線方向に移動自在であり、第１の位置にあるときには、図１０に示すように、補助スリーブ７９Ｂの最内側の係合リング１５４ｃがスリーブ状本体８０Ｂの小突部１５６を乗り越えた位置に位置し、また第２の位置にあるときには、図９に示すように、補助スリーブ７９Ｂの先端側の二つの係合リング１５４ａ，１５４ｂの間にこの小突部１５６が位置するようになる。 In this embodiment, a plurality of (three in this example) engagement rings 154a, 154b, and 154c are attached to the hexagonal inner peripheral surface of the auxiliary sleeve 79B at intervals in the axial direction. The rings 154a, 154b and 154c constitute the engaging means. The engagement rings 154a, 154b, 154c are formed in, for example, a hexagonal shape corresponding to the inner peripheral surface shape of the auxiliary sleeve 79B. Further, a hexagonal small protrusion 156 protruding outward in the radial direction is provided on the outer peripheral surface of the sleeve-like main body 80B of the connecting pipe member 60B. Since the auxiliary sleeve 79B is configured in this way, the auxiliary sleeve 79B is axially out of the first position (position shown in FIG. 10) accommodated in the annular accommodating recess 88 of the connection pipe member 60B and the other end of the connection pipe member 60B. Between the second position protruding in the direction (the position shown in FIG. 9) in the axial direction and when in the first position, as shown in FIG. 10, the innermost engagement of the auxiliary sleeve 79B. When the coupling ring 154c is located at a position over the small protrusion 156 of the sleeve-like main body 80B and is at the second position, as shown in FIG. 9, the two engagement rings 154a on the distal end side of the auxiliary sleeve 79B are disposed. , 154b, the small protrusion 156 is positioned.

That is, in this connection, the valve housing main body 54B is pulled downward in FIG. 9 to position the auxiliary sleeve 79B in the second position shown in FIG. 9, and in this state, the other end of the auxiliary sleeve 79B (for example, When the hexagonal part) is rotated in the tightening direction by a tightening tool (not shown), the connection pipe member 60B is rotated integrally with the auxiliary sleeve 79B in the tightening direction, and thus the connection pipe The male screw portion 82 of the member 60B is screwed to the stove side connecting portion (not shown) of the gas stove.

そして、かく螺着した後、弁ハウジング本体５４Ｂの第２接続部５８にガス配管の雄ねじ部（図示せず）を螺着し、その後、弁ハウジング本体５４Ｂをガスコンロ側に上方に押し上げる。かくすると、ガスコンロに接続された接続管部材６０Ｂに対して弁ハウジング本体５４Ｂ及び補助スリーブ７９Ｂが相対的に上方に移動され、これによって、弁ハウジング本体５４Ｂの下方に比較的大きいスペースを確保することができる。また、補助スリーブ７９Ｂが第１の位置に位置付けられ、その一端側が接続管部材６０Ｂの環状収容凹部８８に収容され、管接続具５２Ｂの上下方向の占有高さが小さくなる。このように、この第３の実施形態の管接続具５２Ｂを用いた場合にも、上述したと同様に、ガス配管を管接続具５２Ｂを介してガスコンロに接続することができ、第１の実施形態と同様の作用効果を達成することができる。 Then, after screwing, a male screw portion (not shown) of the gas pipe is screwed to the second connection portion 58 of the valve housing main body 54B, and then the valve housing main body 54B is pushed upward to the gas stove side. As a result, the valve housing body 54B and the auxiliary sleeve 79B are moved relatively upward with respect to the connecting pipe member 60B connected to the gas stove, thereby ensuring a relatively large space below the valve housing body 54B. Can do. Further, the auxiliary sleeve 79B is positioned at the first position, and one end thereof is accommodated in the annular accommodating recess 88 of the connection pipe member 60B, and the occupied height in the vertical direction of the pipe connection tool 52B is reduced. As described above, even when the pipe connector 52B of the third embodiment is used, the gas pipe can be connected to the gas stove via the pipe connector 52B as described above. The effect similar to a form can be achieved.

ガスコンロから管接続具５２Ｂを取り外すには、弁ハウジング本体５４Ｂを下方（ガスコンロから離隔する方向）に引き下げて補助スリーブ７９Ｂを第２の位置に位置付け、このような状態にて、補助スリーブ７９Ｂを離脱方向（緩み方向）に回動すればよい。弁ハウジング本体５４Ａを下方に引き下げると、連結リング１６０を介して補助スリーブ７９Ａが第２の位置に位置付けられ、かかる状態にて補助スリーブ７９Ａを離脱方向に回動すると、補助スリーブ７９Ｂと一体的に接続管部材６０Ｂが離脱方向に回動され、このようにして、弁ハウジング本体５４Ｂにガス配管が接続された状態でもって、ガスコンロから管接続具５２Ｂの接続管部材６０Ｂを着脱自在に取り外すことができる。 To remove the pipe connector 52B from the gas stove, the valve sleeve main body 54B is pulled downward (in the direction away from the gas stove) to position the auxiliary sleeve 79B in the second position, and in this state, the auxiliary sleeve 79B is detached. What is necessary is just to rotate to a direction (loosening direction). When the valve housing main body 54A is pulled downward, the auxiliary sleeve 79A is positioned at the second position via the connection ring 160. When the auxiliary sleeve 79A is rotated in the disengagement direction in this state, the auxiliary sleeve 79A is integrated with the auxiliary sleeve 79B. The connecting pipe member 60B is rotated in the disengagement direction. Thus, the connecting pipe member 60B of the pipe connector 52B can be detached from the gas stove with the gas pipe connected to the valve housing body 54B. it can.
