(A) and (B) are a longitudinal sectional view and an enlarged longitudinal sectional view of an essential part schematically showing the configuration of the eccentric tube before alignment, and FIGS. 4 and 5 are the eccentric tube before and after alignment. FIG. 6 (A) and FIG. 6 (B) are a longitudinal sectional view and a main part enlarged longitudinal sectional view schematically showing the configuration of the eccentric tube after alignment.

まず、図1に示すように、この実施の形態に係る偏心管は、浴室等の壁W(図3(A)参照)に埋設した湯水供給用の給湯配管および給水配管(以下、単に配管ともいう)Tに湯水混合水栓Mを接続するために用いるものである。そして、図1および図2に示すように、前記偏心管は、ほぼクランク状の偏心管本体1と、この偏心管本体1の湯水導入部2を前記配管Tに接続するためのねじ込み式の管継手3と、環状の化粧カバー4とを備えている。   First, as shown in FIG. 1, the eccentric pipe according to this embodiment includes a hot water supply pipe and a water supply pipe (hereinafter simply referred to as a pipe) embedded in a wall W of a bathroom or the like (see FIG. 3A). This is used to connect the hot and cold water faucet M to T. As shown in FIGS. 1 and 2, the eccentric tube includes a substantially crank-shaped eccentric tube body 1 and a screw-in tube for connecting the hot water introduction portion 2 of the eccentric tube body 1 to the pipe T. A joint 3 and an annular decorative cover 4 are provided.

ここで、前記管継手3には、図2および図3(A)に示すように、互いに締め付け方向が逆向きとなる二つのねじ部(この実施の形態では雄ねじ部)5,6を前後に設けてあり、これに対応させて、一方のねじ部5が螺着する第1螺着部(この実施の形態では雌ねじ部)7を前記配管Tに設け、他方のねじ部6が螺着する第2螺着部(この実施の形態では雌ねじ部)8を前記湯水導入部2に設けてある。   Here, as shown in FIG. 2 and FIG. 3 (A), the pipe joint 3 is provided with two screw portions (in this embodiment, male screw portions) 5 and 6 whose fastening directions are opposite to each other. Corresponding to this, a first screwed portion (in this embodiment, a female screw portion) 7 to which one screw portion 5 is screwed is provided in the pipe T, and the other screw portion 6 is screwed. A second threaded portion (in this embodiment, a female thread portion) 8 is provided in the hot water introduction portion 2.

また、図3(A)および(B)に示すように、前記第2螺着部8に他方のねじ部6を螺着した状態で内側に入る前記偏心管本体1または管継手3のいずれか一方(この実施の形態では偏心管本体1)の外周部にその周方向に延びる環状の段部(溝)9を設け、他方(この実施の形態では管継手3)に前記段部9に係合し、かつ管継手3に対する偏心管本体1の回転操作を許容する状態と許容しない状態とに変更自在な係合部10を設けてある。   Also, as shown in FIGS. 3A and 3B, either the eccentric pipe body 1 or the pipe joint 3 entering the inside with the other screw part 6 screwed to the second screw part 8. An annular step portion (groove) 9 extending in the circumferential direction is provided on the outer peripheral portion of one (in this embodiment, the eccentric tube main body 1), and the other (the pipe joint 3 in this embodiment) is engaged with the step portion 9. In addition, an engaging portion 10 is provided that can be changed between a state in which the rotation operation of the eccentric tube body 1 with respect to the pipe joint 3 is allowed and a state in which the eccentric operation is not allowed.

一方、図2および図3(A)に示すように、前記偏心管本体1は、内部を通過する湯水の流量を調整する流量調整弁11を有する流量調整部12と、前記湯水混合水栓Mに接続する接続部13とを備えている。   On the other hand, as shown in FIG. 2 and FIG. 3 (A), the eccentric tube main body 1 includes a flow rate adjusting unit 12 having a flow rate adjusting valve 11 for adjusting the flow rate of hot water passing through the inside, and the hot water / water mixing faucet M. And a connection part 13 connected to the.

他方、図2および図3(A)に示すように、前記管継手3の外周部にはシール部材(例えばOリング)14を設け、偏心管本体1と管継手3との間からの水漏れを防止している。   On the other hand, as shown in FIGS. 2 and 3A, a seal member (for example, an O-ring) 14 is provided on the outer peripheral portion of the pipe joint 3 so that water leaks between the eccentric pipe body 1 and the pipe joint 3. Is preventing.

さらに、この実施の形態において、前記係合部10は例えばなべ小ねじ等のねじ部材であり、このねじ部材が螺着するねじ穴15を偏心管本体1の湯水導入部2に設けてある。   Further, in this embodiment, the engaging portion 10 is a screw member such as a pan head screw, and a screw hole 15 into which the screw member is screwed is provided in the hot water introduction portion 2 of the eccentric tube main body 1.

尚、前記湯水混合水栓M、偏心管本体1の流量調整部12および接続部13、化粧カバー4の構成は公知のものを採用することができるので、そのより詳細な説明はここでは省略する。   In addition, since the configurations of the hot and cold water mixing tap M, the flow rate adjusting portion 12 and the connecting portion 13 of the eccentric tube main body 1, and the decorative cover 4 can be adopted, a detailed description thereof is omitted here. .

次に、上記の構成からなる偏心管を位置合わせして湯水混合水栓Mを配管Tに接続する方法について説明する。まず、事前準備として、図2に示す分解状態となっている偏心管を組み立てる必要があり、そのために、前記偏心管本体1の第2螺着部8に管継手3のねじ部6を螺着した後、係合部(ねじ部材)10をねじ穴15に螺着して、係合部10を環状の段部(溝)9に係合可能な状態にする。但し、前記係合部10の先端を段部9の底に当接させず離間させておき、管継手3に対する偏心管本体1の回転操作を許容する状態としておく。他方、前記化粧カバー4は管継手3に装着しておく。   Next, a method of aligning the eccentric pipe having the above-described configuration and connecting the hot and cold water mixing tap M to the pipe T will be described. First, as an advance preparation, it is necessary to assemble the eccentric tube in the disassembled state shown in FIG. 2. For this purpose, the screw portion 6 of the pipe joint 3 is screwed to the second screw portion 8 of the eccentric tube body 1. After that, the engaging portion (screw member) 10 is screwed into the screw hole 15 so that the engaging portion 10 can be engaged with the annular step portion (groove) 9. However, the front end of the engaging portion 10 is separated from the bottom of the stepped portion 9 without being brought into contact with the bottom of the stepped portion 9 so as to allow the rotation operation of the eccentric tube main body 1 with respect to the pipe joint 3. On the other hand, the decorative cover 4 is attached to the pipe joint 3.

そして、上記の状態の二つの偏心管をそれぞれ配管Tに接続する。この接続は、配管Tに設けた第1螺着部7に管継手3のねじ部5を螺着することによって行い、この際、前記ねじ部5は右ねじ部であることから、図4に示すように、管継手3を右回りに回動させる。   Then, the two eccentric tubes in the above state are connected to the pipe T, respectively. This connection is performed by screwing the threaded portion 5 of the pipe joint 3 to the first threaded portion 7 provided in the pipe T. At this time, since the threaded portion 5 is a right-hand threaded portion, FIG. As shown, the pipe joint 3 is rotated clockwise.

ここで、管継手3に設けたねじ部5とねじ部6との締め付け方向が逆向きになっていることは既に述べた通りであり、ねじ部5が右ねじ部になっているのに対してねじ部6は左ねじ部となっている。従って、上記管継手3を右回り(ねじ部5を締め付ける向き)に回動させるということはねじ部6を緩める向きに回動するということであり、この回動操作を続ければ偏心管本体1の第2螺着部8に対するねじ部6の螺着がやがて解除されてしまうとも思われる。しかし、この実施形態では、前記係合部10が段部9に係合するので、上記解除は確実に防止され、不具合が生じることはない。   Here, as already described, the tightening direction of the threaded portion 5 and the threaded portion 6 provided in the pipe joint 3 is opposite, whereas the threaded portion 5 is a right-hand threaded portion. The thread portion 6 is a left-hand thread portion. Therefore, turning the pipe joint 3 clockwise (in the direction of tightening the screw part 5) means turning in the direction of loosening the screw part 6, and if this turning operation is continued, the eccentric pipe body 1 is rotated. It seems that the screwing of the screw part 6 to the second screwing part 8 will be released soon. However, in this embodiment, since the engaging portion 10 engages with the stepped portion 9, the release is surely prevented and no malfunction occurs.

上記のように管継手3を配管Tに接続した直後は、図3(A)および(B)に示すように、係合部10は段部9の前側、すなわち前記壁Wから遠い側(図中左側)に当接した状態となっている。そして、今度は、図5に示すように前記偏心管本体1を左回りに回動操作して、偏心管本体1の接続部13が湯水混合水栓Mに接続可能な適宜の位置にくるように位置合わせ(微調整)を行う。   Immediately after connecting the pipe joint 3 to the pipe T as described above, as shown in FIGS. 3A and 3B, the engaging portion 10 is on the front side of the step portion 9, that is, on the side far from the wall W (see FIG. It is in contact with the middle left). Then, as shown in FIG. 5, the eccentric tube main body 1 is turned counterclockwise so that the connecting portion 13 of the eccentric tube main body 1 comes to an appropriate position where it can be connected to the hot and cold water mixing tap M. Align (fine-adjust) to.

ここで、前記段部9の前後方向の幅は5.5mmであり、係合部10の径は3mmであるため、2.5mmのクリアランスがあり、これによって偏心管本体1は上記左回りの回動操作時には360°自由に回転する。   Here, since the width of the step portion 9 in the front-rear direction is 5.5 mm and the diameter of the engaging portion 10 is 3 mm, there is a clearance of 2.5 mm, whereby the eccentric tube body 1 is rotated counterclockwise. During the rotation operation, it is freely rotated 360 °.

そして、上記位置合わせのために偏心管本体1を左回りに回動操作すると、前記係合部10が段部9の後側に向かって幾らか移動することになる。すなわち、位置合わせ後の偏心管は図6(A)および(B)に示す状態となり、この状態を維持するために、前記係合部10を螺進させてその先端を段部9に当接させ、管継手3に対する偏心管本体1の回転を許容する状態から許容しない状態に変更する。   When the eccentric tube main body 1 is turned counterclockwise for the above alignment, the engaging portion 10 moves somewhat toward the rear side of the step portion 9. That is, the eccentric tube after the alignment is in the state shown in FIGS. 6A and 6B, and in order to maintain this state, the engagement portion 10 is screwed and the tip abuts against the step portion 9. Then, the state of allowing the eccentric tube main body 1 to rotate with respect to the pipe joint 3 is changed to a state not allowing it.

上記操作により、偏心管本体1は作業者が手を放しても上記位置合わせした状態を保つため、この状態の偏心管に対して上記湯水混合水栓Mを容易に取り付けることができ、この取付けによって配管Tに対する湯水混合水栓Mの接続が完了する。   By the above operation, the eccentric tube main body 1 maintains the above-mentioned aligned state even if the operator releases the hand. Therefore, the hot water / water mixing faucet M can be easily attached to the eccentric tube in this state. This completes the connection of the hot and cold water mixing tap M to the pipe T.

上記の構成を備えた偏心管では、係合部10を利用して偏心管本体1を所望の位置に保持することができるので、偏心管本体1の位置合わせ作業や湯水混合水栓Mの取付け作業を行う際に、困難で熟練を要するような作業を不要とすることができ、上記作業の簡便化を図ることが可能となる。   In the eccentric tube having the above-described configuration, the eccentric tube main body 1 can be held at a desired position by using the engaging portion 10, so that the alignment operation of the eccentric tube main body 1 and the attachment of the hot and cold water mixing tap M are performed. When the work is performed, a difficult and skillful work can be eliminated, and the above work can be simplified.

しかも、前記偏心管の個々の構成は極めてシンプルであるので、製造が容易であり製造コストの削減を達成することも可能である。   In addition, the individual configuration of the eccentric tube is very simple, so that it is easy to manufacture and it is possible to achieve a reduction in manufacturing cost.

尚、本発明は上記実施の形態に限られず、種々に変形して実施することができる。例えば、上記実施の形態では、ねじ部5を右ねじ部、ねじ部6を左ねじ部としているが、逆にしてもよい。また、ねじ部5,6を雌ねじ部、第1、第2螺着部7,8を雄ねじ部とし、前記段部9を湯水導入部2の外周部に設け、ねじ穴15を管継手3に設けてもよい。   The present invention is not limited to the above embodiment, and can be implemented with various modifications. For example, in the above embodiment, the screw part 5 is a right-hand thread part and the screw part 6 is a left-hand thread part, but may be reversed. The threaded portions 5 and 6 are female threaded portions, the first and second screwed portions 7 and 8 are male threaded portions, the stepped portion 9 is provided on the outer peripheral portion of the hot water introducing portion 2, and the screw hole 15 is formed in the pipe joint 3. It may be provided.
