配管連結具は、凹溝に継手及びシール部材を嵌めて、第２連結片を正しく閉じることで配管どうしの連結が担保される。このため、配管連結具が正しく装着されているかどうかを確認する必要があるが、装置には多数の配管連結具が配置されるため、個々の配管連結具の装着状態を確認することは困難であり、また、確認後であっても、装着状態が維持されているかどうか、さらなる確認が必要となる。 By fitting the joint and the seal member into the groove and properly closing the second connecting piece, the pipe connection is ensured. For this reason, it is necessary to check whether the pipe connectors are properly attached. However, since a large number of pipe connectors are arranged in the equipment, it is difficult to check the attachment state of each individual pipe connector. Also, even after confirmation, further confirmation is required to see if the wearing state is maintained.

図１乃至図５は、本発明の一実施形態に係る装着確認具１０を装着した配管連結具３０を示している。図に示すように、配管連結具３０は、本実施形態では、略Ｃ字状の第１連結片３１と、第１連結片３１にヒンジ接続部３９により揺動可能に連繋され、第１連結片３１に対して開閉可能な第２連結片３５を具える。第１連結片３１と第２連結片３５の内周には、凹溝３２，３６が形成されており、図示しない継手付き配管の継手どうしを、シール部材を介して突き合わせて第１連結片３１の凹溝３２に収容した状態で、第２連結片３５を閉じることで、継手付き配管の連結状態が維持される。 1 to 5 show a pipe connector 30 fitted with a fitting confirmation tool 10 according to one embodiment of the present invention. As shown in the figure, in this embodiment, the pipe connector 30 is connected to a substantially C-shaped first connecting piece 31 and the first connecting piece 31 via a hinge connecting portion 39 so as to be able to swing. A second connecting piece 35 that can be opened and closed with respect to the piece 31 is provided. Grooves 32 and 36 are formed on the inner peripheries of the first connecting piece 31 and the second connecting piece 35, and joints of pipes with joints (not shown) are butted against each other via a sealing member to form the first connecting piece 31. By closing the second connecting piece 35 while being accommodated in the concave groove 32, the connected state of the pipe with the joint is maintained.

配管連結具３０は、図１、図４及び図５に示すように、ヒンジ接続部３９とは逆の端縁又は端縁の近傍にそれぞれ引掛片３３，３７が突設されている。引掛片３３，３７は、対向しない面に引掛溝３４，３８が凹設されており、次に説明する装着確認具１０が装着される。引掛片３３，３７は、配管連結具３０を継手付き配管に装着し、第１連結片３１に対して第２連結片３５を閉じ方向に引き寄せる際に、指や治具で摘まむために形成されている。 As shown in FIGS. 1, 4 and 5, the pipe connector 30 has hooking pieces 33 and 37 projecting from the edge opposite to the hinge connecting portion 39 or near the edge. The hooking pieces 33 and 37 have hooking grooves 34 and 38 recessed on the surfaces not facing each other, and the attachment confirmation tool 10 described below is attached. The hooking pieces 33 and 37 are formed to be grasped with fingers or a jig when the pipe connector 30 is attached to the pipe with a joint and the second connecting piece 35 is pulled toward the first connecting piece 31 in the closing direction. there is

装着確認具１０は、図１乃至図５に示すように、上記した引掛片３３，３７を利用して配管連結具３０に装着される。装着確認具１０の詳細を図６乃至図１１に示す。装着確認具１０は、図６及び図７に示すように、略矩形に構成された縦フレーム１１１，１１と横フレーム１２，１６、横フレーム１２，１６に設けられた爪片１３，１７を具える。装着確認具１０は、ポリプロピレンなどの樹脂から形成することができ、配管連結具３０に装着されている、或いは、装着されていないことを容易に視認できるように、着色を施すことが望ましい。着色は、装着確認具１０の品番、サイズなどに応じて変えることができる。 The attachment checker 10 is attached to the pipe connector 30 using the hooking pieces 33 and 37 described above, as shown in FIGS. Details of the mounting confirmation tool 10 are shown in FIGS. 6 to 11. FIG. As shown in FIGS. 6 and 7, the attachment confirmation tool 10 includes vertical frames 111, 11 and horizontal frames 12, 16 each having a substantially rectangular shape, and claw pieces 13, 17 provided on the horizontal frames 12, 16. I get it. The attachment checker 10 can be made of a resin such as polypropylene, and is preferably colored so that it can be easily seen whether it is attached to the pipe connector 30 or not. Coloring can be changed according to the product number, size, etc. of the attachment confirmation tool 10 .

縦フレーム１１，１１は、図１、図６乃至図８に示すように、配管連結具３０の外周面に沿う形状であり、図中上端側は配管連結具３０から離れる方向に拡大している。縦フレーム１１，１１は、少なくとも引掛片３３，３７が内部に嵌まる間隔を有する。 As shown in FIGS. 1 and 6 to 8, the vertical frames 11, 11 have a shape along the outer peripheral surface of the pipe connector 30, and the upper end side in the figure is expanded in the direction away from the pipe connector 30. . The vertical frames 11, 11 have a space at least for fitting the hooking pieces 33, 37 inside.

横フレーム１２，１６は、図中上側の第１横フレーム１２と下側の第２横フレーム１６であり、縦フレーム１１，１１の端部どうしをそれぞれ連結している。 The horizontal frames 12 and 16 are the first horizontal frame 12 on the upper side in the figure and the second horizontal frame 16 on the lower side, and connect the ends of the vertical frames 11 and 11, respectively.

第１横フレーム１２は、図６、図７、図９及び図１０に示すように、第２横フレーム１６に向けて内向きに突設された第１爪片１３を有する。図示の実施形態では、第１爪片１３は、幅広の板状部材である。第１爪片１３は、第１横フレーム１２と直交する方向に揺動可能に形成される。たとえば、図９及び図１０に示すように、第１爪片１３は、第１横フレーム１２との間に薄肉部１４を有し、薄肉部１４が撓み変形することにより、第１爪片１３を第１横フレーム１２に対して揺動可能とすることができる。 6, 7, 9 and 10, the first horizontal frame 12 has a first claw piece 13 projecting inward toward the second horizontal frame 16. As shown in FIGS. In the illustrated embodiment, the first claw piece 13 is a wide plate-like member. The first claw piece 13 is formed to be swingable in a direction perpendicular to the first horizontal frame 12 . For example, as shown in FIGS. 9 and 10, the first claw piece 13 has a thin portion 14 between itself and the first horizontal frame 12, and when the thin portion 14 is flexurally deformed, the first claw piece 13 is expanded. can be made swingable with respect to the first horizontal frame 12 .

第１爪片１３は、先端１３ａが図４及び図５に示すように、引掛片３３の引掛溝３４に上手く嵌まるようにアール形状としている。また、第１爪片１３は、板状としているため、図１及び図６に示すように、装着される配管連結具３０の種類に応じた品番、サイズ等の記号１５を付することができ、装着確認具１０の種別を視認することができる。 The first claw piece 13 has a rounded shape so that the tip 13a can be well fitted into the hooking groove 34 of the hooking piece 33 as shown in FIGS. Moreover, since the first claw piece 13 is plate-shaped, as shown in FIGS. , the type of the attachment confirmation tool 10 can be visually recognized.

第２横フレーム１６は、図６、図７、図９及び図１１に示すように、第１横フレーム１２に向けて内向きに突設された第２爪片１７を有する。図示の実施形態では、第２爪片１７は、第２横フレーム１６の略中央に突設された第２爪片本体１８と、その両側に突設された略円弧状の第２爪片補助体１９，１９である。 6, 7, 9 and 11, the second horizontal frame 16 has a second claw piece 17 projecting inward toward the first horizontal frame 12. As shown in FIGS. In the illustrated embodiment, the second claw piece 17 includes a second claw piece main body 18 projecting substantially in the center of the second horizontal frame 16 and substantially arc-shaped second claw piece auxiliary projections projecting from both sides thereof. Body 19,19.

第２爪片本体１８は、先端が引掛片３７の引掛溝３８に上手く嵌まるようにアール形状としており、第１爪片１３に比して幅狭に形成されている。 The second claw piece main body 18 has a rounded shape so that the tip can be well fitted into the hooking groove 38 of the hooking piece 37 , and is narrower than the first claw piece 13 .

第２爪片補助体１９，１９は、細幅の四分の一円弧形状であり、先端が第２爪片本体１８よりも突出しており、互いに対向している。第２爪片補助体１９，１９は、細幅形状とすることでバネ性を具備し、第２爪片本体１８を引掛溝３８に嵌めたときにダンパーとして作用し、装着確認具１０のがたつきを抑えることができる。 The second claw piece assisting bodies 19, 19 have a narrow quarter arc shape, and their tips protrude beyond the second claw piece main body 18 and are opposed to each other. The second claw piece auxiliary bodies 19, 19 have a narrow width and have spring properties. It can reduce sagging.

然して、上記構成の装着確認具１０は配管連結具３０に装着される。図１２は、装着確認具１０を配管連結具３０に装着する過程を示す図である。図に示すように、配管連結具３０は、第１連結片３１と第２連結片３５が閉じた状態で装着確認具１０が装着される。装着確認具１０は、たとえば先に第２爪片１７を引掛片３７の引掛溝３８に嵌める。そして、第１爪片１３を矢印Ｆ方向に配管連結具３０側に押すと、薄肉部１４により第１爪片１３が第１横フレーム１２に対して押し出され、第１爪片１３の先端１３ａが上方に回動する。これにより、第１爪片１３と第２爪片１７との間隔が広がるから、この状態で第１爪片１３を引掛片３３の引掛溝３４に嵌めることができ、このまま装着確認具１０を矢印Ｇに示すように配管連結具３０に向けて押し付ける。これにより、薄肉部１４を可動部として、てこの原理により装着確認具１０が配管連結具３０側に引き上げられつつ引き寄せられ、第２爪片補助体１９，１９が撓んだ状態で、図１乃至図５に示すように、装着確認具１０を配管連結具３０に装着できる。 Thus, the attachment confirmation tool 10 having the above configuration is attached to the pipe connector 30 . 12A and 12B are diagrams showing the process of mounting the mounting confirmation tool 10 to the pipe connector 30. FIG. As shown in the figure, the pipe connector 30 is attached to the attachment confirmation tool 10 in a state in which the first connection piece 31 and the second connection piece 35 are closed. For example, the attachment checker 10 first fits the second claw piece 17 into the hooking groove 38 of the hooking piece 37 . When the first claw piece 13 is pushed toward the piping connector 30 in the direction of arrow F, the first claw piece 13 is pushed out from the first horizontal frame 12 by the thin portion 14, and the tip 13a of the first claw piece 13 is pushed out. rotates upward. As a result, the space between the first claw piece 13 and the second claw piece 17 is widened, so that the first claw piece 13 can be fitted into the hook groove 34 of the hook piece 33 in this state, and the mounting checker 10 is moved as it is. Press toward pipe connector 30 as shown at G. As a result, the mounting checker 10 is pulled up and drawn toward the pipe connector 30 by the principle of leverage with the thin portion 14 as a movable portion, and the second claw piece assisting bodies 19, 19 are flexed, as shown in FIG. As shown in FIG. 5, the attachment checker 10 can be attached to the pipe connector 30. As shown in FIG.

図４に示すように、装着確認具１０は、第１爪片１３と第２爪片１７の第２爪片本体１８が引掛片３３，３７の引掛溝３４，３８に嵌まり、装着状態を維持する。また、図５に示すように、第２爪片補助体１９は、そのバネ性により撓んだ状態で引掛溝３８に押し付けられ、装着確認具１０のぐらつきを抑えることができる。 As shown in FIG. 4, the mounting confirmation tool 10 is configured so that the second claw piece body 18 of the first claw piece 13 and the second claw piece 17 is fitted into the hooking grooves 34 and 38 of the hooking pieces 33 and 37 to confirm the mounting state. maintain. Further, as shown in FIG. 5, the second claw piece auxiliary body 19 is pressed against the hooking groove 38 in a bent state due to its springiness, so that the mounting confirmation tool 10 can be prevented from wobbling.

本発明の装着確認具１０は、継手付き配管に配管連結具３０を取り付けた後、第１連結片３１と第２連結片３５を完全に閉じた状態でしか装着することができない。従って、装着確認具１０の装着を目視により確認するだけで、配管連結具３０が正しく取り付けられていることを判別できる。一方、装着確認具１０が装着されていない場合には、配管連結具３０が正しく取り付けられていない、或いは、正しく取り付けられていることが確認されていないため、再度配管連結具３０の取付状態を確認し、装着確認具１０を装着すればよい。 The attachment checker 10 of the present invention can only be attached in a state in which the first connection piece 31 and the second connection piece 35 are completely closed after the pipe connector 30 is attached to the pipe with a joint. Accordingly, it is possible to determine whether the pipe connector 30 is correctly attached only by visually confirming the attachment of the attachment checker 10 . On the other hand, if the attachment confirmation tool 10 is not attached, the pipe connector 30 is not attached correctly, or it is not confirmed that it is attached correctly, so the attachment state of the pipe connector 30 is checked again. After confirming, the attachment confirmation tool 10 may be attached.

図１３は、配管連結具３０の第１連結片３１と第２連結片３５が完全には閉じておらず、開いた状態を示している。この場合、上記と同じ要領で装着確認具１０を装着しようとすると、丸囲み部Ｈで示すように第１爪片１３が引掛片３３と干渉し、装着確認具１０は、配管連結具３０に装着することができないことがわかる。 FIG. 13 shows a state in which the first connecting piece 31 and the second connecting piece 35 of the pipe connector 30 are not completely closed but open. In this case, if the attachment confirmation tool 10 is attached in the same manner as described above, the first hook piece 13 interferes with the hook piece 33 as indicated by the circled portion H, and the attachment confirmation tool 10 is attached to the pipe connector 30. I know I can't wear it.

この場合、第１連結片３１と第２連結片３５を完全に閉じて装着確認具１０を再度装着すればよい。 In this case, the first connecting piece 31 and the second connecting piece 35 may be completely closed and the mounting confirmation device 10 may be mounted again.

或いは、図１４に示すように、第２爪片１７を引掛片３７の引掛溝３８に引っかけた状態で、図１４中矢印Ｉで示すように、第１爪片１３をさらに押して回動させる。そして、装着確認具１０を矢印Ｊ方向に示すように配管連結具３０側に押し込み、第１爪片１３の先端１３ａが引掛片３３を超えて引掛溝３４に引っ掛かるように位置させる。この状態から、装着確認具１０を矢印Ｋ方向に引き上げる。これにより、薄肉部１４を可動部として、てこの原理により装着確認具１０は、第２連結片３５を第１連結片３１に近づくように引き寄せるから、開状態にあった第１連結片３１と第２連結片３５を閉じることができる。すなわち、装着確認具１０の装着と同時に第１連結片３１と第２連結片３５が完全に閉じた状態にあることを担保できる。従って、第１連結片３１と第２連結片３５を予め閉じておく作業が不完全であっても装着確認具１０を装着する際に、装着確認具１０により第１連結片３１と第２連結片３５を完全に閉じることができるから、作業性を可及的に高めることができる。 Alternatively, as shown in FIG. 14, with the second claw piece 17 hooked in the hooking groove 38 of the hooking piece 37, the first claw piece 13 is further pushed and rotated as indicated by the arrow I in FIG. Then, the mounting checker 10 is pushed toward the pipe connector 30 in the direction of arrow J, and positioned so that the tip 13a of the first claw piece 13 goes over the hooking piece 33 and is caught in the hooking groove 34 . From this state, the mounting confirmation tool 10 is pulled up in the arrow K direction. As a result, the installation checker 10 draws the second connecting piece 35 closer to the first connecting piece 31 by the principle of leverage with the thin portion 14 as a movable portion. The second connecting piece 35 can be closed. That is, it is possible to ensure that the first connecting piece 31 and the second connecting piece 35 are completely closed at the same time when the mounting confirmation tool 10 is mounted. Therefore, even if the operation of closing the first connecting piece 31 and the second connecting piece 35 in advance is incomplete, the first connecting piece 31 and the second connecting piece 31 can be connected by the mounting confirmation tool 10 when the mounting confirmation tool 10 is mounted. Since the piece 35 can be completely closed, workability can be enhanced as much as possible.

なお、第１爪片１３を引掛溝３４に嵌めた後、矢印Ｋ方向に装着確認具１０を引き上げると、第１爪片１３が引掛溝３４から外れてしまうことがある。この場合、図１４中符号３３ａで示すように第１連結片３１は、引掛片３３に対して引掛溝３４を挟んだ周面に突起を形成しておけばよい。突起３３ａを設けることで、矢印Ｋ方向に装着確認具１０を引き上げたときに、第１爪片１３の先端１３ａが突起３３ａに当たって引掛溝３４から外れ難くすることができ、作業性をさらに高めることができる。 After the first claw piece 13 is fitted in the hooking groove 34 , the first claw piece 13 may come off the hooking groove 34 when the attachment checker 10 is pulled up in the direction of the arrow K. In this case, as indicated by reference numeral 33a in FIG. 14, the first connecting piece 31 may have projections formed on the peripheral surface of the hooking piece 33 with the hooking groove 34 interposed therebetween. By providing the protrusion 33a, when the mounting confirmation tool 10 is pulled up in the direction of the arrow K, the tip 13a of the first claw piece 13 hits the protrusion 33a and can be prevented from coming off from the hooking groove 34, thereby further improving workability. can be done.

なお、本発明の装着確認具１０を配管連結具３０から取り外す場合には、第１横フレーム１２側を斜め下方に引っ張ればよい。これにより、第１爪片１３の薄肉部１４が撓んで装着確認具１０が傾き、続いて第１爪片１３が引掛溝３４から外れて、配管連結具３０から容易に取り外すことができる。 When the attachment checker 10 of the present invention is removed from the pipe connector 30, the side of the first horizontal frame 12 may be pulled obliquely downward. As a result, the thin portion 14 of the first claw piece 13 bends to tilt the mounting confirmation tool 10, and then the first claw piece 13 is released from the hooking groove 34, so that it can be easily removed from the pipe connector 30. - 特許庁
