Description

本発明は、被接続管の開口部に対して枝管を連通させるように接続するための分岐継手に関する。 The present invention relates to a branch joint for connecting a branch pipe so as to communicate with an opening of a connected pipe.

従来、この種の分岐継手としては、例えば、被接続管の外周面に装着される半円筒状の被装着部としてのサドル部の側部の開口に対して、枝管が挿入される円筒状の枝管接続部を周方向に回動可能に取り付け、サドル部の開口に挿入された枝管接続部の端部に径方向に弾性変形可能な爪状の係止部を形成した構成が知られている。そして、この構成では、係止部を弾性変形させつつ被接続管の開口部に挿入してこの開口部の縁部に係合させた状態で枝管接続部を周方向に回動させることにより、係止部を枝管接続部の径方向に押圧して分岐継手を被接続管に係止固定する(例えば、特許文献１参照。)。 Conventionally, as this kind of branch joint, for example, a cylindrical shape into which a branch pipe is inserted into an opening at a side portion of a saddle portion as a semi-cylindrical attached portion attached to an outer peripheral surface of a connected pipe A structure is known in which a branch pipe connecting portion is rotatably attached in the circumferential direction, and a claw-like locking portion that is elastically deformable in the radial direction is formed at the end of the branch pipe connecting portion inserted into the opening of the saddle portion. It has been. In this configuration, the branch pipe connecting portion is rotated in the circumferential direction while being inserted into the opening of the connected pipe while being elastically deformed and engaged with the edge of the opening. Then, the locking portion is pressed in the radial direction of the branch pipe connecting portion to lock and fix the branch joint to the connected pipe (see, for example, Patent Document 1).

しかしながら、このような構成では、係止部を被接続管の開口部に弾性変形させつつ挿入する際に大きな力や経験を要し、分岐継手の取り付けが確実でないことがある。 However, in such a configuration, a large force or experience is required when inserting the locking portion into the opening of the connected pipe while being elastically deformed, and the attachment of the branch joint may not be reliable.

この点、枝管接続部の端部に別体の係止具を係止し、この係止具を係止した状態で、枝管接続部の外周に螺合させた嵌合体を締め付けることで、枝管接続部を係止具とともに被接続管から遠ざかる方向へと移動させて、係止具を被接続管の開口部の縁部に押圧して分岐継手を被接続管に係止固定する構成が知られている(例えば、特許文献２参照。)。 In this regard, a separate locking tool is locked to the end of the branch pipe connection portion, and with the locking tool locked, the fitting body screwed onto the outer periphery of the branch pipe connection portion is tightened. The branch pipe connecting portion is moved together with the locking tool in a direction away from the connected pipe, and the locking tool is pressed against the edge of the opening of the connected pipe to lock and fix the branch joint to the connected pipe. The configuration is known (see, for example, Patent Document 2).

しかしながら、このような構成では、分岐継手を被接続管に確実に固定できる一方で、係止具を枝管接続部と別体としたことで、分岐継手の取り付けの際に係止具が外れやすく、施工性が良好でないという問題がある。 However, in such a configuration, while the branch joint can be securely fixed to the connected pipe, the locking tool is separated from the branch pipe connecting portion so that the locking tool can be detached when the branch joint is attached. There is a problem that it is easy and the workability is not good.

この点、係止具を枝管接続部に軸支して分岐継手の取り付けの際に係止具が外れないようにした構成が知られている(例えば、特許文献３および４参照。)。 In this regard, a configuration is known in which the locking tool is pivotally supported on the branch pipe connecting portion so that the locking tool is not removed when the branch joint is attached (see, for example, Patent Documents 3 and 4).

しかしながら、このような構成でも、分岐継手を被接続管に取り付ける際には、枝管接続部の内部に作業者が手を挿入して係止具を被接続管の開口部の縁部に嵌め込む必要があり、施工性が良好でないという問題がある。 However, even in such a configuration, when attaching the branch joint to the connected pipe, the operator inserts a hand into the branch pipe connecting portion and fits the locking tool to the edge of the opening of the connected pipe. There is a problem that workability is not good.

次に、上記第１の実施の形態の作用を説明する。 Next, the operation of the first embodiment will be described.

まず、分岐継手14は、予めサドル部26と枝管接続部28とを連結して組み立てておく。すなわち、嵌着凹部46に枝管シール部材47を嵌着しＯリング51を下端側の外周に嵌着した枝管接続部28をサドル部26の取付部33に挿入して、爪部39を嵌合溝部55に嵌合させるとともに嵌合凸部54を取付部33の嵌着溝部38に嵌合させるように周方向に所定角度(９０°程度)回動させてサドル部26と枝管接続部28とを互いに一体的に固定した後、サドル部26の軸支板35，35間に操作部23を、軸支ピンP2を介して回動可能に軸支し、各取付開口部37に対して、サドル部開口27側から各係止体22の各軸部61を挿入し、これら軸部61を各取付開口部37の外部で、各操作部23に対して軸支ピンP1により回動可能に軸支する。この結果、サドル部26のサドル部開口27と枝管接続部28が液密に接続される。 First, the branch joint 14 is assembled by connecting the saddle portion 26 and the branch pipe connecting portion 28 in advance. That is, the branch pipe connecting portion 28 in which the branch pipe seal member 47 is fitted in the fitting recess 46 and the O-ring 51 is fitted to the outer periphery on the lower end side is inserted into the mounting portion 33 of the saddle portion 26, and the claw portion 39 is The saddle portion 26 is connected to the branch pipe by rotating it by a predetermined angle (about 90 °) in the circumferential direction so that the fitting convex portion 54 is fitted to the fitting groove portion 38 of the mounting portion 33 while being fitted to the fitting groove portion 55. After the portion 28 is integrally fixed to each other, the operation portion 23 is pivotally supported between the shaft support plates 35 and 35 of the saddle portion 26 via the shaft support pin P2, and is attached to each mounting opening 37. On the other hand, the shaft portions 61 of the locking bodies 22 are inserted from the side of the saddle portion opening 27, and the shaft portions 61 are rotated by the shaft support pins P1 with respect to the operation portions 23 outside the mounting openings 37. It is pivotally supported. As a result, the saddle portion opening 27 of the saddle portion 26 and the branch pipe connecting portion 28 are connected in a liquid-tight manner.

そして、組み立てた分岐継手14は、図２および図４に示すように、摘み部77，77を持ち上げるように操作部23，23を、軸支ピンP2を中心として回動させることにより、連結部78，78の被ガイド部83，83がガイド面64，64に沿って下方へとガイドされて各連結部78に軸支ピンP1を介して連結された軸部61，61が取付開口部37，37に沿って下方へと押し込まれ、各係止体22が、枝管接続部28に対して中心軸方向へと突出した状態となる。 As shown in FIGS. 2 and 4, the assembled branch joint 14 rotates the operation parts 23, 23 around the pivot pin P <b> 2 so as to lift the knobs 77, 77. The guided portions 83 and 83 of 78 and 78 are guided downward along the guide surfaces 64 and 64, and the shaft portions 61 and 61 connected to the respective connecting portions 78 via the shaft support pins P1 are the mounting openings 37. , 37 is pushed downward, and each locking body 22 protrudes in the direction of the central axis with respect to the branch pipe connecting portion 28.

この後、ホールソーなどにより開口部12を形成した被接続管11の上部に、組み立てた分岐継手14のサドル部26を、開口部12とサドル部開口27とを位置合わせしつつ載置する。 Thereafter, the saddle portion 26 of the assembled branch joint 14 is placed on the connected pipe 11 in which the opening portion 12 is formed by a hole saw or the like while the opening portion 12 and the saddle portion opening 27 are aligned.

この状態で、図１および図３に示すように、作業者が操作部23，23の摘み部77，77を下方、すなわち被接続管11の外周面側へと、軸支ピンP2を中心として回動させることにより、梃子の作用によって操作部23，23の連結部78，78の被ガイド部83，83がガイド面64，64に沿って上方へとガイドされて各連結部78に軸支ピンP1を介して連結された軸部61，61が取付開口部37，37に沿って上方へと移動し、各係止体22の係止爪74がサドル部開口27の縁部に下側から係合してサドル部26との間で被接続管11の開口部12の周縁部を上下から挟持し、さらに各操作部23の被ガイド部83の係止凹部84(図５)と各係止体22の各軸部61の切欠凹部66とがサドル部26の係止突起部65に嵌合することで各操作部23が固定部86により本体部21に固定されて、分岐継手14が被接続管11に一体的に固定される。このとき、各係止体22の軸部61，61は、段差部67，67が切欠段差部71，71に嵌合して軸部シール部材72，72が切欠段差部71，71に圧接され、係止体本体62は、上側が嵌合凹部41に嵌合する。このため、軸部61，61と取付開口部37，37との隙間は、軸部シール部材72，72により液密に閉塞され、サドル部26の内周面と被接続管11の外周面との隙間は、シール部材32により液密に閉塞される。 In this state, as shown in FIGS. 1 and 3, the operator moves the knobs 77, 77 of the operation parts 23, 23 downward, that is, toward the outer peripheral surface of the connected pipe 11, with the pivot pin P 2 as the center. By rotating, the guided portions 83 and 83 of the connecting portions 78 and 78 of the operating portions 23 and 23 are guided upward along the guide surfaces 64 and 64 by the action of the lever, and are pivotally supported by the connecting portions 78. The shaft portions 61, 61 connected via the pin P1 move upward along the mounting openings 37, 37, and the locking claws 74 of the respective locking bodies 22 are located below the edge of the saddle portion opening 27. The peripheral edge of the opening 12 of the connection pipe 11 is sandwiched from above and below between the saddle portion 26 and the engagement recess 84 (FIG. 5) of the guided portion 83 of each operation portion 23 and each Each operating portion 23 is fixed to the main body portion 21 by the fixing portion 86 by fitting the notch recess 66 of each shaft portion 61 of the locking body 22 with the locking projection 65 of the saddle portion 26, and the branch joint 14 Is integrally fixed to the connected pipe 11 It is. At this time, the shaft portions 61 and 61 of the respective locking bodies 22 have the step portions 67 and 67 fitted into the notch step portions 71 and 71, and the shaft portion seal members 72 and 72 are pressed against the notch step portions 71 and 71. The upper side of the locking body 62 is fitted into the fitting recess 41. Therefore, the gap between the shaft portions 61, 61 and the mounting openings 37, 37 is liquid-tightly closed by the shaft seal members 72, 72, and the inner peripheral surface of the saddle portion 26 and the outer peripheral surface of the connected pipe 11 The gap is liquid-tightly closed by the seal member 32.

この後、枝管接続部28に対して枝管を上側から挿入すると、枝管は下端部が段部44に当接することで位置決めされ、この枝管の外周面と枝管接続部28の内周面との隙間は、枝管シール部材47により液密に閉塞されて、被接続管11に対して枝管が分岐される。 Thereafter, when the branch pipe is inserted into the branch pipe connection portion 28 from the upper side, the branch pipe is positioned by abutting the lower end portion against the step portion 44, and the outer peripheral surface of this branch pipe and the inside of the branch pipe connection portion 28 are positioned. The gap with the peripheral surface is liquid-tightly closed by the branch pipe seal member 47, and the branch pipe branches off from the connected pipe 11.

また、分岐継手14を被接続管11から取り外す際には、まず、枝管接続部28から枝管を抜き取り、次いで、図２および図４に示すように、各操作部23の摘み部77，77を上方へと、すなわち被接続管11から持ち上げるように軸支ピンP2を介して回動させると、梃子の作用によって連結部78，78の被ガイド部83，83がガイド面64，64に沿って下方へとガイドされて各連結部78に軸支ピンP1を介して連結された軸部61，61が取付開口部37，37に沿って下方へと押し込まれ、各係止体22が、枝管接続部28に対して中心軸方向へと突出した状態となり、サドル部26と係止爪74とによる被接続管11の上下からの挟持が解除される。したがって、作業者は、この状態で分岐継手14を被接続管11から持ち上げるだけで取り外すことができる。 When removing the branch joint 14 from the connected pipe 11, first, the branch pipe is extracted from the branch pipe connecting portion 28, and then, as shown in FIGS. When 77 is rotated upward, that is, through the pivot pin P2 so as to be lifted from the connected tube 11, the guided portions 83 and 83 of the coupling portions 78 and 78 are moved to the guide surfaces 64 and 64 by the action of the lever. The shaft portions 61, 61 guided downward along the shafts and coupled to the respective coupling portions 78 via the pivot pins P1 are pushed downward along the mounting openings 37, 37, and the respective locking bodies 22 are Thus, the branch pipe connecting portion 28 protrudes in the central axis direction, and the saddle portion 26 and the locking claws 74 are released from the upper and lower sides of the connected pipe 11. Therefore, the operator can remove the branch joint 14 simply by lifting it from the connected pipe 11 in this state.

上述したように、上記第１の実施の形態によれば、本体部21に回動可能に設けた各操作部23を本体部21の外部から操作することで各係止体22を本体部21に対して移動させて係止爪74を被接続管11の開口部12の縁部に係合させ、かつ、この係止爪74の係合状態で各係止体22および各操作部23を固定部86により本体部21に対して固定することにより、被接続管11に対して良好な施工性で分岐継手14を確実に取り付けできる。 As described above, according to the first embodiment, each locking body 22 is moved from the outside of the main body 21 to each main body 21 by operating each operation section 23 provided rotatably on the main body 21. The engaging claw 74 is engaged with the edge of the opening 12 of the connected tube 11, and each engaging body 22 and each operating portion 23 are moved in the engaged state of the engaging claw 74. By fixing to the main body portion 21 by the fixing portion 86, the branch joint 14 can be reliably attached to the connected pipe 11 with good workability.

すなわち、作業者は、各操作部23を回動操作するだけで、係止爪74を被接続管11の開口部12の縁部に容易に係合させることができるので、この係合作業に過度の力や経験、すなわち「こつ」を必要とすることなく分岐継手14を被接続管11に確実に固定でき、また、各係止体22は、本体部21の枝管接続部28の内部に手などを挿入することなく本体部21の外部から動作させることができ、この作業中に本体部21から外れたりすることもないなど、良好な施工性を得ることができる。 In other words, the operator can easily engage the engaging claw 74 with the edge of the opening 12 of the connected pipe 11 simply by rotating each operation portion 23. The branch joint 14 can be securely fixed to the connected pipe 11 without requiring excessive force or experience, that is, “hanging”, and each locking body 22 is provided inside the branch pipe connecting portion 28 of the main body portion 21. It is possible to operate from the outside of the main body portion 21 without inserting a hand or the like, and it is possible to obtain good workability such as no detachment from the main body portion 21 during this work.

さらに、分岐継手14を被接続管11から取り外す場合でも、各操作部23を比較的小さく操作するだけで係止爪74を開口部12の縁部に係合させた状態を容易に解除でき、分岐継手14を被接続管11から容易に取り外しできる。 Furthermore, even when the branch joint 14 is removed from the connected pipe 11, the state in which the locking claw 74 is engaged with the edge portion of the opening portion 12 can be easily released simply by operating each operation portion 23 relatively small. The branch joint 14 can be easily detached from the connected pipe 11.

そして、各操作部23を本体部21に対してそれぞれ回動可能に軸支し、軸支ピンP2を支点として各操作部23の回動により各係止体22を移動させることにより、梃子の作用によって各操作部23を操作する力を抑制しながら、換言すれば各操作部23に過度な力を加えたり各操作部23を大きく動かしたりすることなく各係止体22を容易に移動させることができ、施工性をより向上できる。 Then, each operation part 23 is pivotally supported with respect to the main body part 21, and each locking body 22 is moved by the rotation of each operation part 23 with the pivot pin P2 as a fulcrum. In other words, while suppressing the force to operate each operation unit 23 by the action, in other words, each locking body 22 is easily moved without applying excessive force to each operation unit 23 or moving each operation unit 23 greatly. It is possible to improve the workability.

また、サドル部26と枝管接続部28とを別体としているので、これらを一体に製造する場合と比較して、製造性が良好であるとともに、枝管接続部28を例えば可撓継手、あるいは自在継手などの任意の継手などに交換して所望の用途に容易に対応でき、使い勝手が良好である。 In addition, since the saddle portion 26 and the branch pipe connection portion 28 are separated, the manufacturability is good as compared with the case where they are manufactured integrally, and the branch pipe connection portion 28 is made of, for example, a flexible joint, Alternatively, it can be easily adapted to a desired application by exchanging it with an arbitrary joint such as a universal joint, and it is easy to use.
