ところで、各分割体をそれぞれ成形する際に、成形収縮等により変形が生じてしまうと、各分割体を組み合わせたときに互いの分割面が沿わず、組立不良が発生してしまうおそれがある。 By the way, when each divided body is molded, if deformation occurs due to molding shrinkage or the like, the respective divided surfaces do not follow when the divided bodies are combined, and assembly failure may occur.

これを回避するために、各分割体をそれぞれ強制的に撓ませることにより分割面を互いに馴染ませて組み合わせることも考えられる。 In order to avoid this, it is also conceivable to combine the divided surfaces with each other by forcibly bending the divided bodies.

しかし、特許文献１のように、第１分割体及び第２分割体の分割面が環状で全周に亘って開口端縁が設けられていると、第１分割体及び第２分割体の剛性が高くなって撓みにくく、組み合わせる際に分割面を沿わせ難い。 However, as in Patent Document 1, when the dividing surfaces of the first divided body and the second divided body are annular and provided with open edges over the entire circumference, the rigidity of the first divided body and the second divided body is provided. It becomes difficult to bend and become difficult to bend along the split surface when combined.

また、特許文献１のように、樹脂製筒部材を分割構造とすると、組立時に各分割体の分割面がずれたまま接合されてしまうと、接合面積が狭くなって強度低下を招くおそれもある。 Moreover, when the resin-made cylindrical member has a divided structure as in Patent Document 1, if the divided surfaces of the divided bodies are joined while being displaced at the time of assembly, the joining area may be reduced and the strength may be reduced. .

《発明の実施形態１》
図１乃至図３は、本発明の実施形態１に係る樹脂製筒部材１を示す。該樹脂製筒部材１は、直線状の円筒パイプであり、内部に液体又は気体が流通する流通路１０を備えていて、その長手方向両端には、液体又は気体が流入・流出する開口部１０ａが設けられている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiment is merely exemplary in nature.
Embodiment 1 of the Invention
1 to 3 show a resin cylindrical member 1 according to Embodiment 1 of the present invention. The resin tubular member 1 is a straight cylindrical pipe, and includes a flow passage 10 through which liquid or gas flows. Opening portions 10a through which liquid or gas flows in and out at both longitudinal ends thereof. Is provided.

上記樹脂製筒部材１は、長手方向の一方に位置する第１分割体３と、他方に位置する第２分割体５とを互いに組み合わせて当接接合することにより形成されるようになっていて、その分割ラインＬは、第１分割体３に一方の開口部１０ａを形成する開口端縁を含むように、且つ、第２分割体５に他方の開口部１０ａを形成する開口端縁を含むように、上記流通路１０内の液体又は気体の流通方向に対して傾斜設定されている。 The resin cylinder member 1 is formed by abutting and joining the first divided body 3 located on one side in the longitudinal direction and the second divided body 5 located on the other side in combination with each other. The dividing line L includes an opening edge that forms one opening 10a in the first divided body 3 and an opening edge that forms the other opening 10a in the second divided body 5. Thus, the inclination is set with respect to the flow direction of the liquid or gas in the flow passage 10.

上記第１分割体３の反開口部１０ａ側は、側面視及び平面視で先細形状をなしていて、その端縁には、外側方に延出する楕円形状の板状フランジ３１が形成され、該板状フランジ３１の反開口部１０ａ側が分割面３１ｃとなっている。上記第１分割体３の先細部分の板状フランジ３１には、流通方向に沿って第２分割体５側に延びる幅広な板状可撓性延出部（可撓性部分）３１ａが設けられ、上記板状フランジ３１の開口部１０ａ側には、第１分割体３の外面に沿って開口部１０ａ側に延びる略矩形板状の幅広接合部３１ｂが形成されている。 The anti-opening portion 10a side of the first divided body 3 has a tapered shape in a side view and a plan view, and an elliptical plate-like flange 31 extending outward is formed on the edge thereof. The side opposite to the opening 10a of the plate-like flange 31 is a dividing surface 31c. The plate-like flange 31 of the tapered portion of the first divided body 3 is provided with a wide plate-shaped flexible extension portion (flexible portion) 31a extending toward the second divided body 5 along the flow direction. On the opening 10 a side of the plate-like flange 31, a substantially rectangular plate-like wide joint 31 b extending toward the opening 10 a along the outer surface of the first divided body 3 is formed.

上記第２分割体５は、上記第１分割体３と同一の構造をしているので、上記第１分割体３と同一の符号を付し、詳細な説明は省略する。 Since the second divided body 5 has the same structure as the first divided body 3, the same reference numerals as those of the first divided body 3 are used, and detailed description thereof is omitted.

そして、上記第２分割体５を上記第１分割体３に対して軸心周りに１８０度回転させた状態で、上記第１分割体３の可撓性延出部３１ａを上記第２分割体５の接合部３１ｂに対応させるとともに上記第２分割体５の可撓性延出部３１ａを上記第１分割体３の接合部３１ｂに対応させて、互いの分割面３１ｃを振動溶着又は熱板溶着で当接接合することにより、上記第１分割体３及び第２分割体５が互いに組み合わされるようになっている。 Then, in a state where the second divided body 5 is rotated 180 degrees around the axis with respect to the first divided body 3, the flexible extension portion 31a of the first divided body 3 is moved to the second divided body. 5 corresponding to the joint portion 31b of the second divided body 5 and the joint portion 31b of the first divided body 3 so that the divided surfaces 31c are vibration welded or hot plated. By abutting and joining by welding, the first divided body 3 and the second divided body 5 are combined with each other.

上記第１分割体３及び第２分割体５を互いに組み合わせる際、上記第１分割体３及び第２分割体５の成形時に当該第１分割体３及び第２分割体５が成形収縮等により変形していても、上記可撓性延出部３１ａを剛性のある接合部３１ｂに撓ませることにより互いの分割面３１ｃが隙間なく沿うようになるので、組立不良をなくすことができる。 When the first divided body 3 and the second divided body 5 are combined with each other, the first divided body 3 and the second divided body 5 are deformed due to molding shrinkage or the like when the first divided body 3 and the second divided body 5 are molded. Even if it does, since the mutual division | segmentation surface 31c comes along without a gap | interval by bending the said flexible extension part 31a to the rigid junction part 31b, an assembly defect can be eliminated.

また、上記可撓性延出部３１ａ及び接合部３１ｂにより分割面３１ｃの一部が幅広となるので、第１分割体３と第２分割体５とを組み合わせるときに、第１分割体３と第２分割体５との相対位置がずれても、上記可撓性延出部３１ａ及び接合部３１ｂによりそのずれを吸収して接合面積を十分に確保することができる。 In addition, since a part of the dividing surface 31c is widened by the flexible extension part 31a and the joining part 31b, when the first divided body 3 and the second divided body 5 are combined, Even if the relative position with respect to the second divided body 5 is displaced, the displacement can be absorbed by the flexible extending portion 31a and the joining portion 31b to sufficiently secure the joining area.

さらに、分割ラインＬが傾斜設定されることにより形成された第１分割体３及び第２分割体５の先細形状部分が、可撓性を有する可撓性延出部３１ａにより補強されるようになり、当該部分の剛性を高めることができる。 Further, the tapered portions of the first divided body 3 and the second divided body 5 formed by setting the dividing line L to be inclined are reinforced by a flexible extending portion 31a having flexibility. Thus, the rigidity of the part can be increased.

尚、本実施形態１では、第１分割体３及び第２分割体５のそれぞれに可撓性延出部３１ａを設けているが、第１分割体３及び第２分割体５の少なくとも一方に設けられていればよい。 In the first embodiment, each of the first divided body 3 and the second divided body 5 is provided with the flexible extending portion 31a, but at least one of the first divided body 3 and the second divided body 5 is provided. What is necessary is just to be provided.

また、上記第１分割体３及び第２分割体５の分割面３１ｃは、平面視で楕円形状をなしているが、矩形状であってもよい。 Moreover, although the division surface 31c of the said 1st division body 3 and the 2nd division body 5 has comprised the ellipse shape by planar view, a rectangular shape may be sufficient.

また、上記可撓性延出部３１ａは、平面視で矩形状をなしているが、三角形状や半円形状であってもよいし、台形状であってもよい。
《実施形態１の変形例１》
図４は、本発明の実施形態１の変形例１を示す。この変形例１は、以下の点が上記で詳述した実施形態１と異なっている。すなわち、この変形例１では、分割ラインＬの略中央部分に流通方向に沿って延びる部分が設定されていて、当該分割ラインＬが側面視で段差状となっている。 Moreover, although the said flexible extension part 31a has comprised the rectangular shape by planar view, it may be triangular shape, semicircle shape, and trapezoid shape.
<< Variation 1 of Embodiment 1 >>
FIG. 4 shows a first modification of the first embodiment of the present invention. The first modification differs from the first embodiment described in detail above in the following points. That is, in this modification 1, the part extended along a distribution direction is set to the approximate center part of the division line L, and the said division line L becomes a step shape by side view.

したがって、上述した実施形態１に比べて分割面３１ｃの接合面積を広くすることができ、第１分割体３及び第２分割体５を互いに強固に組み合わせることができる。
《実施形態１の変形例２》
図５は、本発明の実施形態１の変形例２を示す。この変形例２は、以下の点が上記で詳述した実施形態１と異なっている。すなわち、この変形例２では、樹脂製筒部材１の長手方向略中央部分が上下に膨出している。 Therefore, compared with Embodiment 1 mentioned above, the joining area of the division | segmentation surface 31c can be enlarged, and the 1st division body 3 and the 2nd division body 5 can be combined firmly mutually.
<< Modification 2 of Embodiment 1 >>
FIG. 5 shows a second modification of the first embodiment of the present invention. The second modification is different from the first embodiment described in detail above in the following points. That is, in the second modification, the substantially central portion in the longitudinal direction of the resin tubular member 1 bulges up and down.

したがって、上述した実施形態１に比べて分割ラインＬの傾斜が緩くなるので、先細形状部分の剛性を高めることができる。
《発明の参考実施形態１》
図６乃至図８は、本発明の参考実施形態１を示す。この参考実施形態１では、樹脂製筒部材１の長手方向略中央部分が傾斜している点と、分割ラインＬが上記各開口部１０ａを形成する２つの開口端縁を上記第２分割体５にのみ含むように設定されている点とが異なるだけで、その他は実施形態１と同じであるため、以下、実施形態１と異なる部分のみを詳細に説明する。 Therefore, since the inclination of the dividing line L becomes gentle as compared with the first embodiment described above, the rigidity of the tapered portion can be increased.
<< Reference Embodiment 1 of the Invention >>

The horizontal portions 1b and 1c extend substantially in the horizontal direction continuously from both ends.

上記第１分割体３は、下方に開口する断面凹状をなしていて、その開口端縁には、外側方に延出する板状フランジ３１が形成されている。該板状フランジ３１の下面は、分割面３１ｃとなっていて、該分割面３１ｃは、上記第１分割体３の流通方向両端側に先細形状を有するように楕円状をなしている。そして、上記第１分割体３の各先細部分における板状フランジ３１には、流通方向に沿って外側方に延びる幅広な板状の可撓性延出部３１ａがそれぞれに設けられていて、この２つの可撓性延出部３１ａは、互いに略平行に延びている。 The said 1st division body 3 has comprised the cross-sectional concave shape opened below, and the plate-shaped flange 31 extended outward is formed in the opening edge. The lower surface of the plate-like flange 31 is a dividing surface 31c, and the dividing surface 31c is elliptical so as to have a tapered shape at both ends in the flow direction of the first divided body 3. The plate-like flange 31 in each tapered portion of the first divided body 3 is provided with a wide plate-like flexible extension portion 31a extending outward along the flow direction. The two flexible extension parts 31a extend substantially parallel to each other.

上記第２分割体５の長手方向略中央上面には、図７に示すように、流通方向に延びる長孔５ｃが形成されている。該長孔５ｃは、傾斜部１ａを中心に水平部１ｂ及び水平部１ｃの一部まで延びていて、その開口周縁には、環状突条部５１が上記板状フランジ３１に対応するように設けられていて、上記環状突条部５１の上面が分割面５１ｃとなっている。上記環状突条部５１の長手方向両端側には、上記第１分割体３の両可撓性延出部３１ａに対応する位置に略矩形板状の幅広接合部５１ａが設けられ、この２つの接合部５１ａは、互いに略平行に延び、それぞれの中央部分には、平面視で略矩形状の凹部５１ｂが形成されている。 As shown in FIG. 7, a long hole 5c extending in the flow direction is formed in the upper surface of the second divided body 5 in the longitudinal center.

図１４は、本発明の参考実施形態１の変形例６を示す。この変形例６は、以下の点が上記で詳述した参考実施形態１と異なっている。すなわち、この変形例６では、樹脂製筒部材１が略くの字状に屈曲していて、分割ラインＬが、当該屈曲部分を横切るように傾斜設定されている。 Therefore, even when the 1st division body 3 is comprised only by a part of inclination part 1a, the effect similar to the reference embodiment 1 can be acquired.
<< Modification 6 of Reference Embodiment 1 >>
Figure 14 shows a sixth modification of Reference Embodiment 1 of the present invention.
