The female-side protrusion insertion hole 16 has an elongated shape in the axial direction X of the other cylindrical pipe 12. The sleeve member 19 is slid in the axial direction X while moving the engagement projection 17 along the female side projection insertion hole 16, and the male side projection insertion hole 13 (see FIG. 2 (b)), the engaging protrusion 17 is locked. In a state where the sleeve member 19 is mounted on the outer peripheral surface of the female side end portion 14 before sliding, the engagement protrusion 17 is positioned at the rear end portion of the female side protrusion insertion hole 16 and the tip thereof is It attaches so that it may not protrude outside from the front-end | tip edge part of the other cylindrical pipe 12 (refer FIG. 2 (a), (b)).

円筒状パイプ１１，１２は、各々、円形の中空断面を有する金属製（アルミニウム製）のパイプ部材である。一方の円筒状パイプ１１のオス側端部１３は縮径されており、この縮径されたオス側端部１３が他方の円筒状パイプ１２のメス側端部１４の先端開口２０に挿入されて、一方の円筒状パイプ１１のオス側端部１３と他方の円筒状パイプ１２のメス側端部１４とが密接状態で重なり合った二重構造の連結部２１が形成される。 The cylindrical pipes 11 and 12 are metal (aluminum) pipe members each having a circular hollow cross section. The male end 13 of one cylindrical pipe 11 is reduced in diameter, and the reduced male end 13 is inserted into the distal end opening 20 of the female end 14 of the other cylindrical pipe 12. A double-structured connecting portion 21 is formed in which the male side end 13 of one cylindrical pipe 11 and the female side end 14 of the other cylindrical pipe 12 overlap each other in close contact.

一方の円筒状パイプ１１のオス側端部１３は、その外周面が急勾配部２２として一旦縮径した後、緩い勾配でさらに先端に向かって徐々に縮径している。他方の円筒状パイプ１２のメス側端部１４は、その内周面が、オス側端部１３の緩い勾配と合致する勾配で先端に向かって拡径している。一方の円筒状パイプ１１のオス側端部１３を、急勾配部２２が先端開口２０の縁部に当接するまで当該先端開口２０を介してメス側端部１４に挿入することにより、連結部２１においてオス側端部１３とメス側端部１４を容易に密接状態とすることができる。 The male side end portion 13 of one cylindrical pipe 11 has its outer peripheral surface once reduced in diameter as a steep slope portion 22 and then gradually reduced in diameter toward the tip with a gentle gradient. The female peripheral end 14 of the other cylindrical pipe 12 has an inner peripheral surface that expands toward the tip with a gradient that matches the gentle gradient of the male end 13. By inserting the male end 13 of one cylindrical pipe 11 into the female end 14 through the tip opening 20 until the steep slope 22 abuts the edge of the tip opening 20 , the connecting portion 21. The male side end 13 and the female side end 14 can be easily brought into close contact with each other.

また、急勾配部２２が先端開口２０の縁部に当接するまでオス側端部１３をメス側端部１４に挿入した状態において、円形のオス側突起挿入穴１５が長円形のメス側突起挿入穴１６の先端部分において合致するような位置に、オス側突起挿入穴１５が形成されている。なお、オス側端部１３の外周面には、オス側端部１３の先端縁部からオス側突起挿入穴１５に至る軸方向Ｘに沿った直線状の突起案内溝２３が形成されており、オス側端部１３を挿入する際及びスリーブ部材１９をスライドさせる際に、メス側突起挿入穴１６に挿入配置されてメス側端部１４の内側に突出する係合突起１７をオス側突起挿入穴１５まで案内する。また、スリーブ部材１９の外周面には、係合突起１７の周方向における位置が判るように、軸方向Ｘに沿った直線状の案内帯２４がリーブ部材１９の縁部から係合突起１７に向けて設けられており、この案内帯２４に突起案内溝２３及びオス側突起挿入穴１５の位置を合わせつつオス側端部１３を挿入することによって、長円形のメス側突起挿入穴１６の先端部分に円形のオス側突起挿入穴１５をスムースに合致させることができる。 Further, in the state where the male end 13 is inserted into the female end 14 until the steep slope portion 22 contacts the edge of the tip opening 20, the circular male protrusion insertion hole 15 is inserted into the oval female protrusion. A male-side protrusion insertion hole 15 is formed at a position that matches the tip of the hole 16. In addition, on the outer peripheral surface of the male side end portion 13, a linear protrusion guide groove 23 is formed along the axial direction X from the leading edge of the male side end portion 13 to the male side protrusion insertion hole 15. When inserting the male end 13 and sliding the sleeve member 19, the engaging protrusion 17 that is inserted into the female protrusion 14 and protrudes inside the female end 14 is inserted into the male protrusion insertion hole. Guide to 15. Further, on the outer peripheral surface of the sleeve member 19, a linear guide band 24 along the axial direction X extends from the edge of the leave member 19 to the engagement protrusion 17 so that the position of the engagement protrusion 17 in the circumferential direction can be seen. By inserting the male side end 13 while aligning the positions of the projection guide groove 23 and the male side projection insertion hole 15 with the guide band 24, the tip of the oval female side projection insertion hole 16 is provided. The circular male protrusion insertion hole 15 can be smoothly matched with the portion.

スリーブ部材１９は、例えば合成樹脂（プラスチック）製の円筒状部材である。スリーブ部材１９の内側面には、オス側突起挿入穴１５に嵌合される大きさの円形の係合突起１７が一体として内側に突出形成されていることにより、当該係合突起１７はその外側がスリーブ部材１９によって覆われる。スリーブ部材１９には、これの軸方向全長に亘って切り込み２５が形成されていることにより、当該切り込み２５の間隔を周方向に拡げて、スリーブ１９を径方向外方に弾性変形させつつ拡径することができ、これによって係合突起１７を径方向内方に押し下げる付勢力を生じさせることができる。 The sleeve member 19 is a cylindrical member made of, for example, synthetic resin (plastic). On the inner surface of the sleeve member 19, a circular engagement protrusion 17 having a size to be fitted in the male-side protrusion insertion hole 15 is integrally formed so as to protrude inward. Is covered by the sleeve member 19. The sleeve member 19 is formed with cuts 25 extending over the entire length in the axial direction, so that the interval between the cuts 25 is expanded in the circumferential direction, and the sleeve 19 is expanded while elastically deforming radially outward. It is possible to generate a biasing force that pushes the engagement protrusion 17 inward in the radial direction.

本第１実施形態によれば、スリーブ部材１９には、切り込み２５を挟んだ両側縁部に外側に突出する指掛け凸部２６が当該縁部に沿って設けられている。指掛け凸部２６に指を掛けることによって、切り込み２５の間隔を周方向に拡げる操作が容易になり、スリーブ部材１９をメス側端部１４に装着する作業や、係合突起１７の係止状態を解除して一対の円筒状パイプ１１，１２を分解する作業をスムースに行うことが可能になる。 According to the first embodiment, the sleeve member 19 is provided with finger hooking convex portions 26 protruding outward on both side edge portions with the cuts 25 sandwiched therebetween. By hooking the finger on the finger-hanging convex portion 26, the operation of widening the interval of the notches 25 in the circumferential direction is facilitated, and the operation of mounting the sleeve member 19 on the female side end portion 14 and the locking state of the engaging protrusion 17 are performed. It becomes possible to perform the operation of releasing and disassembling the pair of cylindrical pipes 11 and 12 smoothly.

そして、本第１実施形態の連結構造１０によれば、以下の簡易な作業によって一対の円筒状パイプ１１，１２を軸方向Ｘに容易に連結一体化することができると共に、継ぎ目部１８を容易に覆い隠して美粧性を向上させることができる。すなわち、係合突起１７をメス側突起挿入穴１６の後端部に位置させてスリーブ部材１９が装着されたメス側端部１４の先端開口２０に対して、突起案内溝２３及び案内帯２４を目印として位置合わせした後に、一方の円筒状パイプ１１のオス側端部１３を他方の円筒状パイプ１２のメス側端部１４に挿入して行く（図２（ａ）参照）。この挿入により、スリーブ部材１９を拡径しつつ係合突起１７は突起案内溝２３に乗り上げ、急勾配部２２が先端開口２０の縁部に当接するまで挿入されてオス側突起挿入穴１５がメス側突起挿入穴１６の先端に合致した状態では係合突起１７は突起案内溝２３の略中央に位置する（図２（ｂ）参照）。オス側突起挿入穴１５をメス側突起挿入穴１６の先端部に合致させたら、スリーブ部材１９を一方の円筒状パイプ１１側にスライドさせれば、オス側突起挿入穴１５に至った係合突起１７は、スリーブ部材１９による径方向内方に向かう弾性付勢力によりオス側突起挿入穴１５に押し込まれて嵌合係止される。これによって一対の円筒状パイプ１１，１２は軸方向Ｘに強固に連結一体化されると共に、スリーブ部材１９は係合突起１７及び継ぎ目部１８を覆って配設される（図２（ｃ）参照）。 According to the connection structure 10 of the first embodiment, the pair of cylindrical pipes 11 and 12 can be easily connected and integrated in the axial direction X by the following simple operation, and the joint portion 18 can be easily formed. The cosmetics can be improved by covering the skin with. That is, the protrusion guide groove 23 and the guide band 24 are formed with respect to the distal end opening 20 of the female side end portion 14 to which the sleeve member 19 is mounted with the engagement protrusion 17 positioned at the rear end portion of the female side protrusion insertion hole 16. After alignment as a mark, the male side end 13 of one cylindrical pipe 11 is inserted into the female side end 14 of the other cylindrical pipe 12 (see FIG. 2A). By this insertion, the engagement protrusion 17 rides on the protrusion guide groove 23 while expanding the diameter of the sleeve member 19, and is inserted until the steeply inclined portion 22 contacts the edge of the tip opening 20, so that the male-side protrusion insertion hole 15 is a female. In a state where it is aligned with the tip of the side protrusion insertion hole 16, the engaging protrusion 17 is positioned at the approximate center of the protrusion guide groove 23 (see FIG. 2B). When the male-side protrusion insertion hole 15 is aligned with the tip of the female-side protrusion insertion hole 16, the engagement protrusion reaching the male-side protrusion insertion hole 15 is achieved by sliding the sleeve member 19 toward one cylindrical pipe 11. 17 is pushed into the male-side protrusion insertion hole 15 by the elastic biasing force directed inward in the radial direction by the sleeve member 19 and is fitted and locked. Accordingly, the pair of cylindrical pipes 11 and 12 are firmly connected and integrated in the axial direction X, and the sleeve member 19 is disposed so as to cover the engagement protrusion 17 and the joint portion 18 (see FIG. 2C). ).

また、本第１実施形態によれば、スリーブ部材１９はメス側端部１４にスライド可能に装着されており、オス側端部１３を挿入するまでは、スリーブ部材１９の先端が他方の円筒状パイプ１２の先端縁部から外側にはみ出さないように取り付けておくことができるので、スリーブ部材１９の装着により円筒状パイプ１２が長くなるのを回避して、組立て前の掃除具の部品が嵩張らないようにすることができる。 Further, according to the first embodiment, the sleeve member 19 is slidably attached to the female side end portion 14, and the distal end of the sleeve member 19 is the other cylindrical shape until the male side end portion 13 is inserted. Since the pipe 12 can be attached so as not to protrude outward from the tip edge portion of the pipe 12, it is possible to avoid the lengthening of the cylindrical pipe 12 due to the mounting of the sleeve member 19, and the parts of the cleaning tool before assembly are bulky. Can not be.

さらに、本第１実施形態の連結構造１０によれば、連結部２１は、一方の円筒状パイプ１１のオス側端部１３と他方の円筒状パイプ１２のメス側端部１４とが相当の長さで密接配置された二重構造を備えているので、清掃具の使用時等において、連結部２１に大きな曲げ応力が加わっても、かかる二重構造のラップ部分で当該曲げ応力を十分に支持することができ、連結部２１に緩みや破損が生じるのを効果的に回避することができる。また、特に、円筒状パイプ１１，１２は、金属製のパイプ部材であるので、曲げ応力に対するさらに強固な支持力を発揮することができる。 Furthermore, according to the connection structure 10 of the first embodiment, the connection portion 21 has a considerable length between the male end portion 13 of one cylindrical pipe 11 and the female end portion 14 of the other cylindrical pipe 12. Since the double structure is closely arranged, even when a large bending stress is applied to the connecting portion 21 when the cleaning tool is used, the bending stress is sufficiently supported by the double structure lap portion. It is possible to effectively avoid loosening and breakage of the connecting portion 21. In particular, since the cylindrical pipes 11 and 12 are metal pipe members, they can exhibit a stronger support force against bending stress.

図３及び図４（ａ）〜（ｃ）は参考例に係るパイプの連結構造３０を示すものである。参考例の連結構造３０もまた、スリーブ部材３１は弾性変形して拡径可能な構成を有し、メス側突起挿入穴３２に挿入配置された係合突起３３を覆ってメス側端部１４の外周面にスライド可能に装着された状態から（図４（ａ）参照）、オス側端部１３を挿入した後に一方の円筒状パイプ１１側にスライドさせることにより（図２（ｂ）参照）、スリーブ部材３１は、係止された係合突起３３及び継ぎ目部１８を覆って配置される（図２（ｃ）参照）。 3 and 4A to 4C show a pipe connection structure 30 according to a reference example .
