一方、蓋体８ｆは、異径管継ぎ手４を覆うように、断面略コの字形状に形成される（図１０参照）。そして、蓋体８ｆの開口両端部の内面側には、内側に向かって突出する係合凸部８ｓが、第１の接続口８ａ側と第２の接続口８ｂ側の箇所にそれぞれ設けられており、この係合凸部８ｓと基台８ｅの前記係合凹部８ｐとが互いに係合することで、蓋体８ｆが基台８ｅに嵌着される。そして、この蓋体８ｆは、長手方向の一方の端部が、大径管保護カバー６の蓋体６ｄに被り、他方の端部が、小径管保護カバー７の蓋体７ｄに被るように配置される。 On the other hand, the lid 8f is formed in a substantially U-shaped cross section so as to cover the different diameter pipe joint 4 (see FIG. 10). Then, on the inner surface side of the open both end portions of the lid 8f, the engagement convex portions 8s protruding inward are provided at the first connection port 8a side and the second connection port 8b side, respectively. The lid 8f is fitted to the base 8e by the engagement of the engagement convex portion 8s and the engagement recess 8p of the base 8e. The lid 8 f is disposed such that one end in the longitudinal direction covers the lid 6 d of the large diameter tube protective cover 6 and the other end covers the lid 7 d of the small diameter tube protective cover 7. Be done.

次に、以上の構成からなる異径管接続部収容カバー装置５の作用効果について説明する。この異径管接続部収容カバー装置５によると、大径管保護カバー６および小径管保護カバー７は、大径管保持部６ａの、大径管２を保持する中心軸６ｂよりも、小径管保持部７ａの、小径管３を保持する中心軸７ｂが、被固定面１に近づいた位置にある。そして、異径管継ぎ手収容カバー８は、異径硬質管継ぎ手４０１を収容することができ、異径硬質管継ぎ手４０１から小径管保持部７ａに向かって、小径硬質管３０１が被固定面１側にたわむようにして下降するための距離を備えた下降スペース８ｄを有する。こうして、異径管継ぎ手収容カバー８に、小径硬質管３０１の下降スペース８ｄを設けることで、大径硬質管２０１および小径硬質管３０１を、大径管保護カバー６および小径管保護カバー７に無理なく収容させることができるとともに、大径管保護カバー６と小径管保護カバー７とを被固定面１に当接させることができる。 Next, the operation and effect of the different diameter pipe connection portion accommodation cover device 5 configured as described above will be described. According to the different diameter pipe connection portion accommodation cover device 5, the large diameter pipe protection cover 6 and the small diameter pipe protection cover 7 are smaller diameter pipes than the central shaft 6b of the large diameter pipe holding portion 6a for holding the large diameter pipe 2. The central axis 7 b of the holding portion 7 a for holding the small diameter pipe 3 is at a position close to the surface 1 to be fixed. The different diameter pipe joint accommodation cover 8 can accommodate the different diameter hard pipe joint 401, and the small diameter hard pipe 301 is on the fixed surface 1 side from the different diameter hard pipe joint 401 toward the small diameter pipe holding portion 7a. It has a descending space 8d with a distance for flexing and descending. Thus, the large diameter hard tube 201 and the small diameter hard tube 301 can not be used as the large diameter tube protective cover 6 and the small diameter tube protective cover 7 by providing the descent space 8 d of the small diameter hard tube 301 in the different diameter tube joint housing cover 8. The large diameter tube protective cover 6 and the small diameter tube protective cover 7 can be brought into contact with the surface 1 to be fixed.

すなわち、この異径管接続部収容カバー装置５によれば、異径管継ぎ手収容カバー８に、小径硬質管３０１の下降スペース８ｄを設けることで、大径管保護カバー６と小径管保護カバー７とを被固定面１に当接させることができ、これにより、大径硬質管２０１および小径硬質管３０１を、従来に見られるようなスペーサーを用いることなく配管することができる。なお、小径可撓管３０２に対しては、その小径可撓管３０２が短い距離で十分に湾曲することから、異径管継ぎ手収容カバー８に下降スペースを設ける必要はないが、設けても良いのは勿論である。 That is, according to the different diameter pipe connection portion accommodation cover device 5, by providing the descent space 8 d of the small diameter hard pipe 301 in the different diameter pipe joint accommodation cover 8, the large diameter pipe protective cover 6 and the small diameter pipe protective cover 7 Can be brought into contact with the surface 1 to be fixed, whereby the large diameter hard tube 201 and the small diameter hard tube 301 can be piped without using a spacer as conventionally seen. Note that for the small diameter flexible tube 302, since the small diameter flexible tube 302 is sufficiently curved in a short distance, it is not necessary to provide a descent space in the different diameter tube joint accommodation cover 8, but it may be provided. Of course.

ここにおいて、被固定面１は、基準となる面であって、例えば、大径管保護カバー６、異径管継ぎ手収容カバー８、小径管保護カバー７の全てに同一厚さのスペーサーが使われている場合（つまり、全体を嵩上げする場合）は、被固定面１は、各スペーサーの上面からなる一つの平面である。一方、前記した「従来に見られるようなスペーサーを用いることなく配管することができる」におけるスペーサーは、軸心合わせのためのスペーサーであって、全体を嵩上げするためのスペーサーを含んではいない。つまり、全体を嵩上げするためのスペーサーをも用いないということではない。 Here, the fixed surface 1 is a reference surface, and for example, a spacer of the same thickness is used for all of the large diameter pipe protection cover 6, the different diameter pipe joint accommodation cover 8 and the small diameter pipe protection cover 7. In the case of (in other words, when raising the whole), the surface 1 to be fixed is a single plane consisting of the upper surface of each spacer. On the other hand, the spacer in the above-mentioned "can be piped without using a spacer as conventionally seen" is a spacer for axial alignment, and does not include a spacer for raising the whole. In other words, it does not mean that the spacer for raising the whole is not used either.

また、異径管継ぎ手収容カバー８の基台８ｅには、異径硬質管継ぎ手４０１を配置する位置を表示する表示部８ｇ（図示実施の形態においては、表示突部８ｉ）が設けられている。このため、この表示部８ｇ（表示突部８ｉ）を目安に、異径硬質管継ぎ手４０１を配置することができる。 Further, the base 8e of the different diameter pipe joint accommodation cover 8 is provided with a display portion 8g (in the illustrated embodiment, a display projection 8i) for displaying the position where the different diameter hard pipe joint 401 is to be disposed. . For this reason, the different diameter hard pipe joint 401 can be disposed with this display portion 8g (display projection 8i) as a guide.

また、異径管継ぎ手収容カバー８において、前記表示突部８ｉを境にして大径管保護カバー６側が、異径硬質管継ぎ手収容スペース８ｈとなり、その反対側が、下降スペース８ｄとなる。そして、この表示突部８ｉにより、異径硬質管継ぎ手４０１を、異径硬質管継ぎ手収容スペース８ｈ内に的確に配置することができる。 Further, in the different diameter pipe joint accommodation cover 8, the large diameter pipe protective cover 6 side with the display projection 8i as a boundary is the different diameter hard pipe joint accommodation space 8h, and the opposite side is a descending space 8d. Then, the different diameter hard pipe joint 401 can be accurately disposed in the different diameter hard pipe joint accommodation space 8 h by the display projection 8 i.

また、異径管継ぎ手収容カバー８は、異径硬質管継ぎ手４０１に代えて、異径可撓管継ぎ手４０２を収容することができる。そこで、この異径管継ぎ手収容カバー８に異径可撓管継ぎ手４０２を収容した場合には、その異径可撓管継ぎ手４０２（詳しくは、凹部４ｇ）に、表示突部８ｉが係合することで、大径管保護カバー６に収容される大径可撓管２０２および／または小径管保護カバー７に収容される小径可撓管３０２（図示実施の形態においては、大径可撓管２０２および小径可撓管３０２）の熱膨張による異径可撓管継ぎ手４０２の移動を規制することができる。
異径管接続部収容構造にあっては、大径管２を収容する大径管保護カバー６と、小径管３を収容する小径管保護カバー７とが、被固定面１に固定されている。そして、大径管２と小径管３とを繋ぐ異径管継ぎ手４を収容する、異径管継ぎ手収容カバー８が設けられる。ここで、前述したように、大径管保護カバー６および小径管保護カバー７は、大径管保持部６ａの、大径管２を保持する中心軸６ｂよりも、小径管保持部７ａの、小径管３を保持する中心軸７ｂが、被固定面１に近づいた位置にある。そこで、異径管継ぎ手４は、異径管継ぎ手収容カバー８内において、異径管継ぎ手４と、異径管継ぎ手収容カバー８の第１の接続口８ａに接続される大径管保護カバー６との間隔よりも、異径管継ぎ手４と、異径管継ぎ手収容カバー８の第２の接続口８ｂに接続される小径管保護カバー７との間隔が広くなるように配置される。そして、大径管２と小径管３とは、異径管継ぎ手４に接続されて、それぞれ大径管保護カバー６と小径管保護カバー７とに収容され、小径管３は、その小径管３が小径管保護カバー７内へと導かれて小径管保持部７ａに保持されるよう、異径管継ぎ手収容カバー８内で、異径管継ぎ手４から小径管保護カバー７に向かって被固定面１側にたわむようにして下降（詳しくは、小径管保持部７ａの中心軸７ｂの位置まで下降）している。こうして、小径管３が、異径管継ぎ手収容カバー８内で、被固定面１側にたわむように下降することで、大径管２および小径管３を、大径管保護カバー６および小径管保護カバー７に無理なく収容させることができるとともに、大径管保護カバー６と小径管保護カバー７とを被固定面１に当接させることができる。これにより、大径管２および小径管３を、スペーサーを用いることなく配管することができる。 Further, the different diameter pipe joint accommodation cover 8 can accommodate the different diameter flexible pipe joint 402 in place of the different diameter hard pipe joint 401. Therefore, when the different diameter flexible pipe joint 402 is accommodated in the different diameter pipe joint accommodation cover 8, the display projection 8i is engaged with the different diameter flexible pipe joint 402 (specifically, the recess 4g). Thus, the large-diameter flexible tube 202 housed in the large-diameter tube protective cover 6 and / or the small-diameter flexible tube 302 housed in the small-diameter tube protective cover 7 (in the illustrated embodiment, the large-diameter flexible tube 202 And the movement of the different-diameter flexible joint 402 due to the thermal expansion of the small-diameter flexible tube 302).
In the different diameter pipe connection portion accommodation structure, the large diameter pipe protection cover 6 for accommodating the large diameter pipe 2 and the small diameter pipe protection cover 7 for accommodating the small diameter pipe 3 are fixed to the fixed surface 1 . A different diameter pipe joint accommodation cover 8 is provided which accommodates a different diameter pipe joint 4 connecting the large diameter pipe 2 and the small diameter pipe 3. Here, as described above, the large diameter tube protective cover 6 and the small diameter tube protective cover 7 are of the small diameter tube holding portion 7a of the large diameter tube holding portion 6a, rather than the central shaft 6b for holding the large diameter tube 2 The central shaft 7 b holding the small diameter pipe 3 is at a position close to the surface 1 to be fixed. Therefore, the different diameter pipe joint 4 is connected to the different diameter pipe joint 4 and the first connection port 8 a of the different diameter pipe joint storage cover 8 in the different diameter pipe joint storage cover 8. The space between the different diameter pipe joint 4 and the small diameter pipe protective cover 7 connected to the second connection port 8b of the different diameter pipe joint housing cover 8 is wider than the space between the two. The large diameter pipe 2 and the small diameter pipe 3 are connected to the different diameter pipe joint 4 and accommodated in the large diameter pipe protective cover 6 and the small diameter pipe protective cover 7 respectively, and the small diameter pipe 3 is the small diameter pipe 3 In the different diameter pipe joint accommodation cover 8 from the different diameter pipe joint 4 toward the small diameter pipe protective cover 7 so that the small diameter pipe protective cover 7 is guided and held by the small diameter pipe holder 7a. As it bends toward 1 side, it descends (specifically, it descends to the position of the central axis 7 b of the small diameter pipe holding portion 7 a). Thus, the large diameter pipe 2 and the small diameter pipe 3 can be divided into the large diameter pipe protection cover 6 and the small diameter pipe by lowering the small diameter pipe 3 so as to bend toward the fixed surface 1 in the different diameter pipe joint housing cover 8. The large diameter tube protective cover 6 and the small diameter tube protective cover 7 can be brought into contact with the surface 1 to be fixed, while being accommodated in the protective cover 7 without difficulty. Thereby, the large diameter pipe 2 and the small diameter pipe 3 can be piped without using a spacer.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、大径管２および小径管３は、給水管でなくとも、給湯管であってもよく、また、排水管、ガス管等、その他の管であってもよい。また、特に、小径管３のみ、あるいは、大径管２および小径管３は、硬質管としての水道用硬質塩化ビニル管からなってもよい。また、異径管継ぎ手４は、異径硬質管継ぎ手４０１であったり、異径可撓管継ぎ手４０２であったりしなくとも、大径可撓管２０２と小径硬質管３０１（例えば、硬質塩化ビニル管）とを繋いだり、反対に、大径硬質管２０１と小径可撓管３０２とを繋ぐ、異種異径管継ぎ手であってもよい。 The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the large diameter pipe 2 and the small diameter pipe 3 may not be a water supply pipe, but may be a hot water supply pipe, or may be other pipes such as a drain pipe, a gas pipe, and the like. Furthermore, in particular, only the small diameter pipe 3 or the large diameter pipe 2 and the small diameter pipe 3 may be made of a hard polyvinyl chloride pipe for water supply as a hard pipe. Further, the different diameter pipe joint 4 is the different diameter hard pipe joint 401 or the different diameter flexible pipe joint 402, and the large diameter flexible pipe 202 and the small diameter hard pipe 301 (for example, hard vinyl chloride It may be a different-differential-diameter pipe joint which connects the tube) and conversely connects the large diameter hard tube 201 and the small diameter flexible tube 302.

また、異径管継ぎ手収容カバー８には、表示部８ｇとしての表示突部８ｉが、基台８ｅから突出して形成され、この表示突部８ｉが、異径硬質管継ぎ手４０１の小径管３０１側の先端に当接可能となるが、この表示突部８ｉが、異径硬質管継ぎ手４０１における第１接続口４ａから第２接続口４ｂに移る段部に当接可能となってもよい。また、この表示突部８ｉは、異径可撓管継ぎ手４０２に対しては、異径可撓管継ぎ手４０２の中間部分（詳しくは、第１接続部４ｃと第２接続部４ｄの間）の凹部４ｇに係合するが、異径可撓管継ぎ手４０２の大径管２０２側の先端（つまり、第１接続口４ｃの先端）に係合したり、異径可撓管継ぎ手４０２の小径管３０２側の先端（つまり、第２接続口４ｄの先端）に係合するようにしてもよい。そして、表示突部８ｉが、異径可撓管継ぎ手４０２の大径管２０２側の先端に係合する場合には、その係合により、小径可撓管３０２の熱膨張による異径可撓管継ぎ手４０２の移動が規制される。反対に、表示突部８ｉが、異径可撓管継ぎ手４０２の小径管３０２側の先端に係合する場合には、その係合により、大径可撓管２０２の熱膨張による異径可撓管継ぎ手４０２の移動が規制される。 Further, in the different diameter pipe joint accommodation cover 8, a display projection 8i as the display portion 8g is formed to protrude from the base 8e, and the display projection 8i is the small diameter pipe 301 side of the different diameter hard pipe joint 401. The display projection 8i may be able to abut on the step portion of the different diameter hard joint 401 moving from the first connection port 4a to the second connection port 4b. Further, the display projection 8i is an intermediate portion of the different diameter flexible pipe joint 402 with respect to the different diameter flexible pipe joint 402 (specifically, between the first connection portion 4c and the second connection portion 4d). The small diameter pipe of the different diameter flexible pipe joint 402 is engaged with the recess 4 g, but is engaged with the tip of the different diameter flexible pipe joint 402 on the large diameter pipe 202 side (that is, the tip of the first connection port 4 c) It may be engaged with the end on the 302 side (that is, the end of the second connection port 4d). Then, when the display projection 8i engages with the tip of the large diameter tube 202 side of the different diameter flexible tube joint 402, the different diameter flexible tube due to the thermal expansion of the small diameter flexible tube 302 by the engagement. The movement of the joint 402 is restricted. On the other hand, when the display protrusion 8i engages with the tip of the small diameter tube 302 of the different diameter flexible pipe joint 402, the different diameter flexibility due to the thermal expansion of the large diameter flexible tube 202 by the engagement. The movement of the pipe fitting 402 is restricted.

また、表示部８ｇは、前述のように表示突部８ｉからなるが、異径可撓管継ぎ手４０２の移動を制限する必要がなければ、突出することのないマークからなっていてもよい。また、この際、異径管継ぎ手収容カバー８の基台８ｅにおける、大径管保護カバー６（詳しくは、基台６ｃ）に突き合わされる端部（すなわち、舌片８ｎの基端を挟む両方の端部）のライン８ｘ（図９参照）を、表示部８ｇ（マーク）とし、その表示部８ｇに、異径管継ぎ手４としての異径硬質管継ぎ手４０１の大径側端（つまり、第１接続口４ａの先端）や異径管継ぎ手４としての異径可撓管継ぎ手４０２の大径側端（つまり、第１接続口４ｃの先端）を合わせるようにしてもよい。 Further, the display portion 8g is composed of the display projection 8i as described above, but may be a mark which does not protrude if it is not necessary to restrict the movement of the different diameter flexible pipe joint 402. At this time, both ends of the base 8e of the different-diameter pipe joint accommodation cover 8 butted against the large-diameter pipe protective cover 6 (specifically, the base 6c) (ie, both sides sandwiching the base end of the tongue 8n) The line 8x (see FIG. 9) of the end portion of FIG. 9 is used as a display 8g (mark), and the large diameter end (that is, the second end) of the different diameter hard pipe joint 401 as the different diameter pipe joint 4 is used. The end of the first connection port 4a) or the large diameter side end (that is, the end of the first connection port 4c) of the different-diameter flexible pipe joint 402 as the different-diameter pipe joint 4 may be aligned.
