持着片１０の開放される端部の内面側には、図４および図５に示すように、パイプ材２に形成された係合孔（後述）に係止するための係止爪１４が筒状部材３の軸心に向かって突出するように形成されている。係止爪１４は、略円柱形状に形成され、図２に示すように、その一部がテーパ状に形成された案内面１５を有している。これは、係止爪１４をパイプ材２の係合孔１６にスムーズに案内されやすくするためである。[0031]
On the inner surface side of the open end of the holding piece 10, as shown in FIGS. 4 and 5, a locking claw 14 for locking in an engagement hole (described later) formed in the pipe material 2 is provided. It is formed to protrude toward the axial center of the cylindrical member 3. The locking claw 14 is formed in a substantially cylindrical shape, and as shown in FIG. 2, has a guide surface 15 of which a part is formed in a tapered shape. This is for the purpose of facilitating smooth guiding of the locking claw 14 into the engagement hole 16 of the pipe member 2.

上記のように構成された連結具１は、以下のようにして使用される。まず、上記連結具１によりパイプ材２を連結する場合について説明する。中軸部材４の一端をパイプ材２に挿入する。この場合、パイプ材２の係合孔１６と中軸部材４の挿通孔５とが一致するように、中軸部材４の半分が隠れる位まで中軸部材４を挿入する。次いで、筒状部材３を中軸部材４およびパイプ材２に覆い被せるように外嵌させる。そして、持着片１０の一端側の係止爪１４をパイプ材２の係合孔１６および中軸部材４の挿通孔５に嵌め込む。このとき、持着片１０は、係止爪１４が係合孔１６に嵌まり込むまでは屈曲されているが、係止爪１４が係合孔１６に嵌まり込むと同時に通常の姿勢に戻る。[0033]
The connector 1 configured as described above is used as follows. First, the case where the pipe material 2 is connected by the connecting tool 1 will be described. One end of the middle shaft member 4 is inserted into the pipe material 2. In this case, the middle shaft member 4 is inserted until the half of the middle shaft member 4 is hidden so that the engagement hole 16 of the pipe member 2 and the insertion hole 5 of the middle shaft member 4 coincide with each other. Then, the cylindrical member 3 is fitted outside so as to cover the center shaft member 4 and the pipe member 2. Then, the locking claw 14 on one end side of the holding piece 10 is fitted into the engagement hole 16 of the pipe member 2 and the insertion hole 5 of the middle shaft member 4. In this case, lifting attachment piece 10 is engaging claw 14 until fitted into the engaging hole 16 is bent, the locking claw 14 returns to the normal posture and simultaneously fitted into the engaging hole 16 .

次に、他方のパイプ材２を取り付ける。すなわち、他方のパイプ材２を、その端面が一方のパイプ材２の端面と当接されるまで、中軸部材４と筒状部材３との間に形成された空間に挿入する。この場合、一方のパイプ材２および中軸部材４は、持着片１０の係止爪１４がそれらの係合孔１６および挿通孔５に係止されていることにより、互いにずれることなく保持される。そして、他方のパイプ材２の係合孔１６と中軸部材４の挿通孔５とが一致するように、パイプ材２を挿入していくと、持着片１０の係止爪１４がパイプ材２の係合孔１６および中軸部材４の挿通孔５に嵌まり込む。これにより、複数本のパイプ材２が、中軸部材４を介して筒状部材３により連結される。[0034]
Next, the other pipe material 2 is attached. That is, the other pipe material 2 is inserted into the space formed between the center shaft member 4 and the cylindrical member 3 until the end surface is in contact with the end surface of the one pipe material 2. In this case, the one pipe member 2 and the center shaft member 4 are held without being deviated from each other by the locking claws 14 of the supporting piece 10 being locked in the engagement holes 16 and the insertion holes 5. . Then, when the pipe material 2 is inserted so that the engagement hole 16 of the other pipe material 2 and the insertion hole 5 of the middle shaft member 4 coincide with each other, the locking claw 14 of the holding piece 10 is the pipe material 2 And the insertion hole 5 of the center shaft member 4. Thereby, the plurality of pipe members 2 are connected by the cylindrical member 3 via the middle shaft member 4.

次に、上記連結具１を取り外すときには、持着片１０の一端をドライバ等の工具やユーザの爪等によりめくり上げ、持着片１０を屈曲させる。そして、係止爪１４が中軸部材４の挿通孔５およびパイプ材２の係合孔１６から完全に離脱した時点で、一方のパイプ材２を引き抜くことにより、両パイプ材２が分離される。なお、この場合、他方のパイプ材２には、中軸部材４および筒状部材３が装着されたままであるが、再度、一方のパイプ材２を取り付ける際には、上記の状態のままの方が時間の節約となるので、差し支えない。[0035]
Next, when the connector 1 is removed, one end of the holding piece 10 is lifted by a tool such as a driver or a user's claw or the like to bend the holding piece 10. Then, when the locking claws 14 completely disengage from the insertion holes 5 of the center shaft member 4 and the engagement holes 16 of the pipe members 2, the two pipe members 2 are separated by pulling out one of the pipe members 2. In this case, although the middle shaft member 4 and the cylindrical member 3 are attached to the other pipe member 2, when one of the pipe members 2 is attached again, the above state remains as it is. It's safe because it saves time.
【００３６】
このようにして、一組のパイプ材２が、筒状部材３および中軸部材４を介して連結および抜脱される。ここで、パイプ材２が連結された場合、連結されたパイプ材２を両側から引っ張っても、持着片１０の係止爪１４がパイプ材２の係合孔１６および中軸部材４の挿通孔５に嵌まり込んでいるので、この係止爪１４によって、持着片１０はパイプ材２に対して保持され、筒状部材３は複数のパイプ材２の連結状態を良好に維持することができる。[0036]
In this manner, the pair of pipe members 2 is connected and disconnected via the cylindrical member 3 and the center shaft member 4 . Here, when the pipe material 2 is connected, even if the connected pipe material 2 is pulled from both sides, the locking claws 14 of the holding piece 10 are the engagement holes 16 of the pipe material 2 and the insertion holes of the center shaft member 4 Since the holding pieces 10 are held against the pipe member 2 by the locking claws 14 because they are fitted in 5, the tubular member 3 can maintain the connected state of the plurality of pipe members 2 in a good condition. it can.
