Description

本発明は、水栓ボックスを使用せずに、水栓接続部が壁裏から壁孔に挿入された水栓継手に対して水栓をがたつくことなく接続可能にした隙間閉塞用スペーサに関するものである。   TECHNICAL FIELD The present invention relates to a gap closing spacer that allows a faucet connection part to be connected to a faucet joint inserted from a back wall into a wall hole without rattling the faucet without using a faucet box. is there.

壁裏に配管された給水管又は給湯管と、壁表に設置される水栓とは、壁材に貫通して形成された壁孔に一部(水栓と接続される水栓接続部)が貫通される水栓継手を介して接続される(特許文献1〜3参照)。この場合において、壁裏に配置される水栓継手における水栓との接続口が壁表を向いた状態で、壁材に対して離れて配置される場合には、当該水栓継手の接続口を壁表に臨ませるべく、当該接続口に短管状の延長接続管が接続されて、当該延長接続管が前記壁孔に挿入されて、壁表に配置される水栓と接続される。   The water supply pipe or hot water supply pipe piped on the back of the wall and the faucet installed on the wall surface are partially in the wall hole formed through the wall material (the faucet connection part connected to the faucet) Is connected through a faucet joint that penetrates (see Patent Documents 1 to 3). In this case, when the connection port with the faucet in the faucet joint arranged on the back of the wall is facing away from the wall material with the connection port facing the wall surface, the connection port of the faucet joint Is connected to a faucet disposed on the wall surface by connecting a short tubular extension connection tube to the connection port and inserting the extension connection tube into the wall hole.

ここで、上記した壁孔の内径は、水栓の水栓接続部又は前記延長接続管の外径に対して大きめに形成され、しかも、水栓と給水管又は給湯管を接続した状態において、現実の配管施工においては、壁孔の中心に対して水栓の水栓接続部又は延長接続管の中心とが一致又はほぼ一致するとは限られず、むしろずれて配管される場合の方が多い。更に、壁材に形成された壁孔の大きさ(内径)が対応する水栓に対して大きく形成されてしまう場合もある。   Here, the inner diameter of the wall hole is formed larger than the faucet connection part of the faucet or the outer diameter of the extension connection pipe, and in the state where the faucet and the water supply pipe or the hot water supply pipe are connected, In actual piping construction, the faucet connection part of the faucet or the center of the extension connecting pipe is not necessarily coincident with or substantially coincident with the center of the wall hole, and rather, the pipe is displaced in many cases. Furthermore, the size (inner diameter) of the wall hole formed in the wall material may be formed larger than the corresponding faucet.

この結果、壁孔に挿入された水栓の水栓接続部又は延長接続管の外周面と、当該壁孔の内周面との間には、不可避的に隙間が形成される。この隙間の存在により、使用時において水栓に作用する負荷は、壁裏の構造物と水栓継手との固定部に集中して作用し、水栓自体が、がたついてしまう。   As a result, a gap is inevitably formed between the faucet connecting portion of the faucet inserted into the wall hole or the outer peripheral surface of the extension connecting pipe and the inner peripheral surface of the wall hole. Due to the presence of the gap, the load acting on the faucet during use is concentrated on the fixing portion between the structure behind the wall and the faucet joint, and the faucet itself rattles.

上記がたつきを回避するために、水栓ボックスと称される水栓継手を収容する専用部材が使用され、当該水栓ボックスのボックス本体に突出して設けられた短管状の固定リング螺着筒が壁裏から壁孔に嵌入され、当該固定リング螺着筒の内側に壁表から固定リングを螺着することで、当該固定リング及び前記壁孔の双方に挿入される水栓継手の水栓接続部が、がたつくのを防止している。   In order to avoid the above-mentioned rattling, a dedicated member for housing a faucet joint called a faucet box is used, and a short tubular fixed ring screwed tube provided protruding from the box body of the faucet box Is inserted into the wall hole from the back of the wall, and the fixing ring is inserted into both the fixing ring and the wall hole by screwing the fixing ring from the wall surface inside the fixing ring screw cylinder. The connecting part prevents rattling.

本発明は、水栓ボックスを使用せずに、水栓接続部が壁裏から壁孔に挿入された水栓継手に対して水栓をがたつくことなく接続可能にすることを課題としている。   An object of the present invention is to make it possible to connect a faucet connection portion to a faucet joint inserted into a wall hole from the back of the wall without using a faucet box without rattling.

上記課題を解決するための請求項1の発明は、水栓が接続される水栓接続部が壁表側に臨むように、壁裏から、壁材に貫通して形成された壁孔内に挿入された状態で、壁裏に設置される水栓継手の当該水栓接続部の外周面と前記壁孔の内周面との間に形成される環状隙間に配置される隙間閉塞用スペーサであって、
前記隙間閉塞用スペーサは、弾性材料により全体が筒状に形成されて、
内部に前記水栓接続部が挿入されることで前記環状隙間に配置され、外周部には、前記壁孔の大きさの相違に対応すべく、軸方向の一端から他端に向けて外径がテーパー状に変化する外径調整部が形成され、
前記外径調整部は、外径の異なる分割部を軸方向に沿って複数備え、
前記複数の分割部の外周面は、軸方向の一端から他端に向けて傾斜角が非直線的に変化する変則部分円錐面に形成されて、各分割部の軸方向の他端にそれぞれ径方向に大きく突出した環状突出部が形成され、
前記各分割部の軸方向の一端には、小径側において隣接する別の分割部の環状突出部が弾性変形により傾動された際に当接して支持する当接支持部が形成されていることを特徴としている。
The invention of claim 1 for solving the above-mentioned problem is inserted into the wall hole formed through the wall material from the back of the wall so that the faucet connection portion to which the faucet is connected faces the front side of the wall. In this state, the gap closing spacer is disposed in an annular gap formed between the outer peripheral surface of the faucet connection portion of the faucet joint installed on the back of the wall and the inner peripheral surface of the wall hole. And
The gap closing spacer is formed in an overall cylindrical shape by an elastic material,
The faucet connection portion is inserted into the annular gap, and the outer peripheral portion has an outer diameter from one end to the other end in the axial direction so as to correspond to the difference in the size of the wall hole. Is formed with an outer diameter adjusting portion that changes into a taper shape,
The outer diameter adjusting portion includes a plurality of divided portions having different outer diameters along the axial direction,
The outer peripheral surfaces of the plurality of divided portions are formed as irregular partial conical surfaces whose inclination angles change in a non-linear manner from one end to the other end in the axial direction, and have diameters at the other ends in the axial direction of the respective divided portions. An annular protrusion that protrudes greatly in the direction is formed,
One end in the axial direction of each of the divided portions is formed with an abutting support portion that abuts and supports when the annular protrusion of another divided portion adjacent on the small diameter side is tilted by elastic deformation. It is a feature.

請求項の発明によれば、外径の異なる複数の分割部が、スペーサの軸方向に沿って複数形成されて、各分割部の軸方向の他端には、それぞれ径方向に大きく突出した環状突出部が独立して形成されているため、壁孔の内径よりも小さな環状突出部は、変形されずに、当該壁孔よりも大きな環状突出部のみが弾性変形されて壁孔の内周面に弾接することで、壁孔に対してスペーサが支持された状態となって配置される。各分割部の外周面は、軸方向の一端から他端に向けて傾斜角が非直線的に変化する変則部分円錐面に形成されていて、各分割部の軸方向に沿った他端には、それぞれ径方向に大きく突出した環状突出部が形成されているため、当該環状突出部は、壁孔に対するスペーサの挿入方向と逆方向に傾動されて、大径側において隣接する別の分割部の当接支持部に当接して支持されるので、環状突出部の傾動状態が安定化する。その結果、壁孔に対するスペーサの支持状態が安定化する。 According to the first aspect of the present invention, a plurality of divided parts having different outer diameters are formed along the axial direction of the spacer, and the other axial end of each divided part protrudes greatly in the radial direction. Since the annular protrusion is formed independently, the annular protrusion smaller than the inner diameter of the wall hole is not deformed, and only the annular protrusion larger than the wall hole is elastically deformed, and the inner periphery of the wall hole By being in elastic contact with the surface, the spacer is arranged in a state of being supported with respect to the wall hole. The outer peripheral surface of each divided portion is formed as an irregular conical surface whose inclination angle changes nonlinearly from one end to the other end in the axial direction, and at the other end along the axial direction of each divided portion. Since each of the annular protrusions projecting greatly in the radial direction is formed, the annular protrusion is tilted in a direction opposite to the insertion direction of the spacer with respect to the wall hole, and is separated from another divided part adjacent on the large diameter side. Since the contact is supported by the contact support portion, the tilted state of the annular protrusion is stabilized. As a result, the support state of the spacer with respect to the wall hole is stabilized.

請求項の発明は、請求項1の発明において、軸方向に沿った一部を切除して、全体の長さを調整するための複数の環状凹溝が軸方向に沿って所定間隔をおいて形成されていることを特徴としている。 According to a second aspect of the present invention, in the first aspect of the present invention, a plurality of annular grooves for adjusting the overall length are cut out along the axial direction by cutting away a part along the axial direction. It is characterized by being formed.

請求項の発明によれば、壁孔に対してスペーサを圧入して環状隙間に配置させる際に、軸方向に沿った一部が不要な場合、又は壁表の水栓を構成する部材と干渉する場合には、当該不要部又は干渉部を環状凹溝の部分で切除して、スペーサを短くして使用する。 According to the invention of claim 2 , when the spacer is press-fitted into the wall hole and disposed in the annular gap, a part along the axial direction is unnecessary, or a member constituting the faucet on the wall surface In the case of interference, the unnecessary portion or interference portion is cut off at the annular groove portion, and the spacer is shortened for use.

本発明によれば、外径の異なる複数の分割部が、スペーサの軸方向に沿って複数形成されて、各分割部の軸方向の他端には、それぞれ径方向に大きく突出した環状突出部が独立して形成されているため、壁孔の内径よりも小さな環状突出部は、変形されずに、当該壁孔よりも大きな環状突出部のみが弾性変形されて壁孔の内周面に弾接することで、壁孔に対してスペーサが支持された状態となって配置される。各分割部の外周面は、軸方向の一端から他端に向けて傾斜角が非直線的に変化する変則部分円錐面に形成されていて、各分割部の軸方向に沿った他端には、それぞれ径方向に大きく突出した環状突出部が形成されているため、当該環状突出部は、壁孔に対するスペーサの挿入方向と逆方向に傾動されて、大径側において隣接する別の分割部の当接支持部に当接して支持されるので、環状突出部の傾動状態が安定化する。その結果、壁孔に対するスペーサの支持状態が安定化する。 According to the present invention, a plurality of divided portions having different outer diameters are formed along the axial direction of the spacer, and the other ends in the axial direction of the divided portions are respectively annular projecting portions that project greatly in the radial direction. Therefore, the annular protrusion smaller than the inner diameter of the wall hole is not deformed, and only the annular protrusion larger than the wall hole is elastically deformed and elastically projected onto the inner peripheral surface of the wall hole. By contacting, the spacer is arranged in a state of being supported with respect to the wall hole. The outer peripheral surface of each divided portion is formed as an irregular conical surface whose inclination angle changes nonlinearly from one end to the other end in the axial direction, and at the other end along the axial direction of each divided portion. Since each of the annular protrusions projecting greatly in the radial direction is formed, the annular protrusion is tilted in a direction opposite to the insertion direction of the spacer with respect to the wall hole, and is separated from another divided part adjacent on the large diameter side. Since the contact is supported by the contact support portion, the tilted state of the annular protrusion is stabilized. As a result, the support state of the spacer with respect to the wall hole is stabilized.

以下、複数の実施例を挙げて、本発明を更に詳細に説明する。   Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

最初に、図1〜図7を参照して、本発明の実施例1のスペーサS1 について説明する。スペーサS1 は、図1及び図2に示されるように、ゴム材、熱可塑性エラストマー等の弾性材料により全体が円筒状に形成されて、軸方向に一定間隔をおいて周方向に形成された複数の環状凹溝1を介して当該環状凹溝1の数よりも「1」だけ多い複数の分割部2に分割されている。各分割部2の外径は、スペーサS1 の軸方向の一端から他端に向けて漸次変化している。図2(c),(d)においては、各分割部2の外径は、スペーサS1 の軸方向に沿って、右端から左端に向けて段階的に大きくなっている。また、各分割部2の外周面は、軸方向の一端から他端に向けて外径が徐々に変化した後に、急激に変化する変則部分円錐面3に形成され、分割部2における外径が急激に変化している部分は、径方向に大きく突出して、壁孔H1 に対する圧入時において、大径側に隣接する別の分割部2の側に弾性変形して傾動可能な環状突出部4となっていると共に、分割部2における外径が徐々に変化する部分は、小径側において隣接する別の分割部2の環状突出部4が傾動した際に当接して支持する当接支持部5(図6参照)となっている。即ち、各分割部2の外周面の変則部分円錐面3は、軸方向の一端から他端に向けて傾斜角が非直線的に変化していて、大径側の端部において大きく径方向に突出している。実施例1のスペーサS1 では、各分割部2の外周側の変則部分円錐面3の部分が、壁孔H1 〜H3 の異なる内径d1 〜d3 に対応して、スペーサS1 の外径を調整する外径調整部となっている。 First, with reference to FIGS. 1 to 7 to describe the spacer S 1 of the first embodiment of the present invention. As shown in FIGS. 1 and 2, the spacer S 1 is formed in a cylindrical shape as a whole by an elastic material such as a rubber material or a thermoplastic elastomer, and is formed in the circumferential direction at a constant interval in the axial direction. The plurality of divided grooves 2 are divided by a plurality of annular grooves 1 by “1” more than the number of the annular grooves 1. The outer diameter of each of the divided portions 2 is gradually changed toward the other end from the one axial end of the spacer S 1. In FIG. 2 (c), (d), the outer diameter of each of the divided portions 2 along the axial direction of the spacer S 1, which is stepwise larger from the right towards the left. Moreover, the outer peripheral surface of each division part 2 is formed in the irregular part cone surface 3 which changes rapidly after the outer diameter changes gradually from one end to the other end in the axial direction. The abruptly changing portion protrudes greatly in the radial direction, and can be tilted by being elastically deformed and tilted toward another divided portion 2 adjacent to the large-diameter side at the time of press-fitting into the wall hole H 1 . In addition, the portion of the divided portion 2 where the outer diameter gradually changes is abutting support portion 5 that abuts and supports when the annular projecting portion 4 of another adjacent divided portion 2 tilts on the small diameter side. (See FIG. 6). In other words, the irregular conical surface 3 of the outer peripheral surface of each divided portion 2 has a non-linear change in inclination angle from one end to the other end in the axial direction, and greatly increases in the radial direction at the end portion on the large diameter side. It protrudes. In the spacer S 1 of Example 1, irregular part portion of the conical surface 3 of the outer peripheral side of each divided portion 2, corresponding to the inner diameter d 1 to d 3 having different wall hole H 1 to H 3, the spacer S 1 It is an outer diameter adjusting part for adjusting the outer diameter.

また、スペーサS1 の内周部には、スプライン状の支持突条6が周方向に一定間隔をおいて軸方向の全長に亘って形成されていて、各支持突条6の内周面は、全長に亘って後述の水栓継手C1 の延長された水栓接続部である延長接続管P0 の外径に対応する円の周上に配置されていて〔図2(c)参照〕、スペーサS1 の中空部7に前記延長接続管P0 を挿入した状態において、当該延長接続管P0 に対してスペーサS1 の内周面は、全長に亘って各支持突条6の当接支持面に当接することで、安定して支持される構造になっている。一方、スペーサS1 における前記支持突条6を除く部分は、当該支持突条6に比較して薄肉に形成されたテーパー円筒部8となっていて、当該テーパー円筒部8の肉厚(T)は、軸方向に沿って一定しているため、スペーサS1 における前記テーパー円筒部8の内周面は、縦断面視で軸方向に沿って傾斜している〔図2(c),(d)参照〕。 In addition, spline-like support ridges 6 are formed on the inner peripheral portion of the spacer S 1 over the entire length in the axial direction at regular intervals in the circumferential direction, and the inner peripheral surface of each support ridge 6 is It is arranged on the circumference of a circle corresponding to the outer diameter of the extension connecting pipe P 0 , which is an extended faucet connection portion of the faucet joint C 1 described later over the entire length [see FIG. 2 (c)]. , in a state where the insertion of the extension connecting pipe P 0 in the hollow portion 7 of the spacer S 1, the inner peripheral surface of the spacer S 1 with respect to the extension connecting pipe P 0 is equivalent over the entire length of each support rib 6 By abutting on the contact support surface, the structure is supported stably. On the other hand, the portion of the spacer S 1 excluding the support ridge 6 is a tapered cylindrical portion 8 formed thinner than the support ridge 6, and the thickness (T) of the tapered cylindrical portion 8. Is constant along the axial direction, the inner peripheral surface of the tapered cylindrical portion 8 in the spacer S 1 is inclined along the axial direction in a longitudinal sectional view [FIGS. )reference〕.

また、スペーサS1 には、対応する水栓の水栓接続部よりも大きな水栓の水栓接続部に対応可能にすべく、当該スペーサS1 の軸方向に沿った切断を容易にするための深溝状の第1切割部9が外周面に開口した状態で軸方向の全長に亘って形成されている。深溝状の第1切割部9の深さは、各分割部2の肉厚が小径側から大径側に向けて徐々に厚くなっていることに対応して、スペーサS1 の軸方向の一端の小径側から他端の大径側に向けて漸次深くなっていて、当該第1切割部9が設けられた部分の肉厚は、テーパー円筒部8の肉厚Tよりも僅かに厚く形成されて、前記第1切割部9は、テーパー円筒部8の肉厚の部分まで形成されていて、切り割りを容易にしている。即ち、スペーサS1 を第1切割部9で切り割って、横断面視で周方向の一部に開口部29〔図8(b)参照〕を形成することで、当該開口部29が形成されたスペーサS1 の中空部7’の内径は、当該開口部29を有しない本来のスペーサS1 の中空部7の内径よりも大きくなって、スペーサS1 が対応する本来の水栓よりもサイズの大きな別の水栓に対して対応可能となる(別の水栓の水栓接続部の外側にスペーサS1 を嵌め込むことができる)。 In addition, the spacer S 1 can be easily cut along the axial direction of the spacer S 1 so as to be compatible with a faucet connection portion of a faucet larger than the faucet connection portion of the corresponding faucet. The deep groove-shaped first slit portion 9 is formed over the entire length in the axial direction with the outer peripheral surface opened. The depth of the first groove portion 9 having a deep groove shape corresponds to one end of the spacer S 1 in the axial direction corresponding to the fact that the thickness of each divided portion 2 gradually increases from the small diameter side toward the large diameter side. The thickness of the portion where the first cut portion 9 is provided is formed slightly thicker than the thickness T of the tapered cylindrical portion 8. The first cutting portion 9 is formed up to the thick portion of the tapered cylindrical portion 8 to facilitate cutting. That is, the opening 29 is formed by cutting the spacer S 1 with the first cutting portion 9 and forming an opening 29 (see FIG. 8B) in a part in the circumferential direction in a cross-sectional view. inner diameter of the hollow portion 7 'of the spacer S 1 is larger than the inner diameter of the original hollow portion 7 of the spacer S 1 does not have the opening 29, the size than the original faucet spacer S 1 is corresponding It is possible to cope with another faucet having a large diameter (the spacer S 1 can be fitted outside the faucet connection portion of another faucet).

また、スペーサS1 における前記第1切割部9に対して周方向に沿って位相が180°異なる部分、即ち、当該第1切割部9と対向する部分には、前記第1切割部9と同様の外周面に開口した第2切割部11が、当該スペーサS1 の小径側の一端から軸方向に沿った中間の部分まで形成されている。第2切割部11の主たる機能は、壁孔H1 に挿入された水栓接続部、或いは水栓接続部としての機能を果す後述の延長接続管P0 の外周面と、当該壁孔H1 の内周面33とで形成される環状隙間K1 (図5参照)にスペーサS1 を圧入させる際に、当該スペーサS1 の小径側の部分を拡開させて、水栓の水栓接続部或いは延長接続管P0 の外側に対するスペーサS1 の嵌め込みを容易にすることであり、他の機能については、後述する。 Further, a portion of the spacer S 1 that is 180 ° out of phase along the circumferential direction with respect to the first cut portion 9, that is, a portion that faces the first cut portion 9 is the same as the first cut portion 9. second Setsuwari portion 11 opened in the outer peripheral surface of is formed from a small diameter side of one end of the spacer S 1 to an intermediate portion along the axial direction. The main functions of the second slit portion 11 are the faucet connecting portion inserted into the wall hole H 1 , or the outer peripheral surface of an extension connecting pipe P 0 described later that functions as a faucet connecting portion, and the wall hole H 1. When the spacer S 1 is press-fitted into the annular gap K 1 formed with the inner peripheral surface 33 (see FIG. 5), the portion on the small diameter side of the spacer S 1 is expanded so that the faucet is connected to the faucet. This is for facilitating the fitting of the spacer S 1 to the outside of the part or the extension connecting pipe P 0 , and other functions will be described later.

次に、図3〜図7を参照して、壁材Wに形成された壁孔H1 に、水栓継手C1 を構成する延長接続管P0 が挿入された状態において、当該延長接続管P0 の外周面と壁孔H1 の内周面33との間に形成される環状隙間K1 に、上記したスペーサS1 を挿入して、当該環状隙間K1 を閉塞する構造について説明する。図3及び図4に示されるように、L字状をした水栓継手C1 は、壁材Wの壁裏に配置されて、L字状のブラケット31を介して横材32に固定される。本配管例では、壁材Wに対して横材32が所定距離だけ離れて配置されているため、水栓継手C1 の水栓接続部21を壁孔H1 に直接に挿入できない。このため、水栓継手C1 の水栓接続部21に短直管状の延長接続管P0 を接続して、当該延長接続管P0 の先端部が壁裏から壁孔H1 に挿入され、壁表において当該延長接続管P0 に水栓Vが接続される。延長接続管P0 の一端部には、壁孔H1 に挿入される一般部22よりも僅かに小径の雄螺子部23が設けられ、当該雄螺子部23が、水栓継手C1 の水栓接続部21の内周面に形成された雌螺子部24に螺合されている。また、延長接続管P0 の先端部には、水栓継手C1 の水栓接続部21に形成された雌螺子部24と同一内径の雌螺子部25が形成されているため、延長接続管P0 の使用により、水栓継手C1 は、当該延長接続管P0 の一般部22の長さだけ、壁表に向けて延長されることになって、水栓継手C1 の水栓接続部21と同等機能を果す延長接続管P0 の先端部を壁孔H1 に挿入可能となる。 Next, referring to FIG. 3 to FIG. 7, in the state where the extension connection pipe P 0 constituting the faucet joint C 1 is inserted into the wall hole H 1 formed in the wall material W, the extension connection pipe the annular gap K 1 which is formed between the inner circumferential surface 33 of the outer peripheral surface and the wall hole H 1 of P 0, by inserting a spacer S 1 described above, a description will be given of the structure for closing said annular gap K 1 . As shown in FIGS. 3 and 4, the L-shaped faucet joint C 1 is disposed on the back of the wall material W and is fixed to the cross member 32 via the L-shaped bracket 31. . In this piping example, since the cross member 32 is arranged at a predetermined distance from the wall material W, the faucet connection portion 21 of the faucet joint C 1 cannot be directly inserted into the wall hole H 1 . For this reason, a short straight tubular extension connecting pipe P 0 is connected to the faucet connecting part 21 of the faucet joint C 1 , and the tip of the extension connecting pipe P 0 is inserted into the wall hole H 1 from the back of the wall, A faucet V is connected to the extension connecting pipe P 0 on the wall surface. One end of the extension connecting pipe P 0 is provided with a male screw portion 23 having a slightly smaller diameter than the general portion 22 inserted into the wall hole H 1 , and the male screw portion 23 is connected to the water of the faucet joint C 1 . It is screwed into a female screw portion 24 formed on the inner peripheral surface of the plug connection portion 21. In addition, since a female screw part 25 having the same inner diameter as the female screw part 24 formed in the faucet connection part 21 of the faucet joint C 1 is formed at the tip of the extension connection pipe P 0 , the extension connection pipe the use of P 0, water faucet fittings C 1 is the length of the common portion 22 of the extension connecting pipe P 0, are to be extended towards the wall table, faucet connecting water faucet fittings C 1 It becomes possible to insert the distal end portion of the extension connecting pipe P 0 that performs the same function as the portion 21 into the wall hole H 1 .

次に、水栓継手C1 及び当該水栓継手C1 に接続される延長接続管P0 を使用して、壁裏に配管された給水管P1 に対して壁表において水栓Vを接続する配管施工について説明する。まず、水栓継手C1 に接続される水栓Vが設定予定位置に配置されるように、壁裏において、当該水栓継手C1 を壁裏予定位置に設置されている横材32にブラケット31を介して固定し、その後に、横材32の配置位置、給水管P1 の呼径、水栓継手C1 のサイズ等の設計図類に記載の既知事項に基づいて算出された位置に、前記既知事項に基づいて算出された内径d1 の壁孔H1 を穿孔した壁材Wを立設させる。その後に、壁表から壁孔H1 を貫通させて、水栓継手C1 の水栓接続部21に延長接続管P0 を接続させて、延長接続管P0 の雌螺子部25と水栓継手C1 の雌螺子部24とが同心となって、水栓継手C1 の水栓接続部21が延長接続管P0 の一般部22の長さだけ壁表側に延長される。なお、延長接続管P0 は、壁材Wの立設前に、水栓継手C1 に接続されて施工してもよい。本配管例では、延長接続管P0 の先端部は、所定長だけ壁表に突出している。 Then use the extension connecting pipe P 0 which is connected to the water faucet fittings C 1 and the faucet joint C 1, connect the water faucet V in wall table for the water supply pipe P 1 which is a pipe in the wall back The piping construction to be performed will be described. First, on the back of the wall, the faucet joint C 1 is bracketed to the cross member 32 installed at the planned back of the wall so that the faucet V connected to the faucet joint C 1 is arranged at the predetermined set position. 31, and then calculated based on known matters described in the design drawings such as the arrangement position of the cross member 32, the diameter of the water supply pipe P 1 , the size of the faucet joint C 1 , etc. The wall material W in which the wall hole H 1 having the inner diameter d 1 calculated based on the known matter is drilled is erected. Then, by penetrating the wall hole H 1 from the wall table, by connecting the extension connecting pipe P 0 to faucet connection portion 21 of the water faucet joint C 1, and the female screw portion 25 of the extension connecting pipe P 0 faucet The female screw portion 24 of the joint C 1 is concentric, and the faucet connection portion 21 of the faucet joint C 1 is extended to the wall surface side by the length of the general portion 22 of the extension connection pipe P 0 . The extension connecting pipe P 0 may be connected to the faucet joint C 1 before the wall material W is erected. In the present piping example, the distal end portion of the extension connecting pipe P 0 protrudes from the wall surface by a predetermined length.

上記したように、壁材Wを立設する前に、横材32に対する水栓継手C1 の固定、水栓継手C1 に対する給水管P1 の接続等を済ませておくために、壁材Wに穿孔される壁孔H1 の内径d1 は、水栓継手C1 の水栓接続部21(又は延長接続管P0 )の外径よりも大きくしないと、壁孔H1 と水栓継手C1 の水栓接続部21(又は延長接続管P0 )とが干渉して、壁孔H1 と水栓継手C1 の水栓接続部21(又は延長接続管P0 )を挿入できないことが発生する。現実の配管施工では、壁孔H1 の軸心J1 に対して水栓継手C1 の水栓接続部21(又は延長接続管P0 )の軸心がずれることの方が多いため、壁孔H1 の内径d1 を水栓継手C1 の水栓接続部21(又は延長接続管P0 )の外径D1 よりも大きくしてある。その結果として、壁孔H1 の内周面33と、水栓継手C1 の水栓接続部21(又は延長接続管P0 )の外周面との間に不可避的に環状隙間K1 が発生し、水栓Vのがたつき防止のために、当該環状隙間K1 を閉塞する必要が生ずる。 As described above, in order to fix the faucet joint C 1 to the cross member 32 and connect the water supply pipe P 1 to the faucet joint C 1 before the wall material W is erected, the wall material W inside diameter d 1 of the wall hole H 1 to be drilled in, if not greater than the outer diameter of the faucet connecting portion 21 water faucet joint C 1 (or extension connection pipe P 0), wall hole H 1 and faucet joint C 1 faucet connecting portion 21 (or the extension connecting pipe P 0) and may interfere, it can not be inserted into the wall holes H 1 and faucet joint C 1 faucet connecting portion 21 (or the extension connecting pipe P 0) Occurs. In actual piping construction, the axis of the faucet connection part 21 (or the extension connection pipe P 0 ) of the faucet joint C 1 is often displaced from the axis J 1 of the wall hole H 1. the inner diameter d 1 of the holes H 1 is made larger than the outer diameter D 1 of the faucet connecting portion 21 water faucet joint C 1 (or extension connection pipe P 0). As a result, an annular gap K 1 is inevitably generated between the inner peripheral surface 33 of the wall hole H 1 and the outer peripheral surface of the faucet connection portion 21 (or the extension connection pipe P 0 ) of the faucet joint C 1. and, in order to prevent rattling of the faucet V, necessary for closing the annular gap K 1 is generated.

その後に、図5に示されるように、必要に応じてスペーサS1 の第2切割部11の部分において、当該スペーサS1 の小径側の部分を切り割って拡開しておき、この状態で、壁表において、延長接続管P0 の先端部から、その外側にスペーサS1 を嵌め込むことにより、相対的に当該スペーサS1 の中空部7に延長接続管P0 の先端部が挿入される。これにより、延長接続管P0 の外周面と壁孔H1 の内周面33とで形成される環状隙間K1 がスペーサS1 により閉塞される。内径d1 の壁孔H1 の場合には、図6に詳細に図示されているように、中央の2つの環状突出部4のみが、壁孔H1 の内周面33に弾接することで大径側に隣接する別の分割部2の側に弾性変形により傾動されて、大径側に隣接する別の分割部2の当接支持部5に当接して支持される。このため、壁孔H1 に対するスペーサS1 の支持力も大きくなって、容易にはずれなくなる。このため、水栓Vに負荷が加わった場合、当該負荷の一部は、負荷作用部から最も近いスペーサS1 に作用して、水栓Vのがたつきを効果的に防止できる。なお、図3及び図4において、34は、L字形の水栓継手C1 における給水管P1 と接続される管接続部を示す。 Thereafter, as shown in FIG. 5, in the portion of the second Setsuwari portion 11 of the spacer S 1 If necessary, leave widened dividing off the small-diameter-side portion of the spacer S 1, in the state in the wall table, from the distal end of the extension connecting pipe P 0, by fitting the spacer S 1 on the outside thereof, the distal end portion of the extension connecting pipe P 0 is inserted into the hollow portion 7 of relatively the spacer S 1 The Thereby, the annular gap K 1 formed by the outer peripheral surface of the extension connecting pipe P 0 and the inner peripheral surface 33 of the wall hole H 1 is closed by the spacer S 1 . In the case of the wall hole H 1 having the inner diameter d 1 , as shown in detail in FIG. 6, only the two central annular protrusions 4 are in elastic contact with the inner peripheral surface 33 of the wall hole H 1. It is tilted to the side of another divided portion 2 adjacent to the large diameter side by elastic deformation, and is in contact with and supported by the contact support portion 5 of another divided portion 2 adjacent to the large diameter side. Therefore, the supporting force of the spacer S 1 for wall hole H 1 be increased, not easily come off. For this reason, when a load is applied to the faucet V, a part of the load acts on the spacer S 1 closest to the load acting portion, and the rattling of the faucet V can be effectively prevented. 3 and 4, reference numeral 34 denotes a pipe connecting portion connected to the water supply pipe P 1 in the L-shaped water faucet joint C 1 .

その後に、壁表において、延長接続管P0 の先端部の内周面に形成された雌螺子部25に水栓Vの雄螺子部26を螺合させると、延長接続管P0 に対して水栓Vが接続される。水栓Vの雄螺子部26には、化粧リング27が螺合されて、壁材Wの表面に密着される。延長接続管P0 の先端部及びスペーサS1 の大径側の一部は、壁表に突出しているが、これらの突出部分の全ては、化粧リング27と壁表面とで形成される空間に収容されて外側からは視認できなくなって、外観が良好となる。 Thereafter, the wall table, when the female thread portion 25 formed on the inner peripheral surface of the distal end portion of the extension connecting pipe P 0 screwing the male screw portion 26 of the faucet V, to the extension connecting pipe P 0 A faucet V is connected. A decorative ring 27 is screwed into the male screw portion 26 of the faucet V and is in close contact with the surface of the wall material W. The distal end portion of the extension connecting pipe P 0 and a part on the large diameter side of the spacer S 1 protrude from the wall surface, but all of these protruding portions are in the space formed by the decorative ring 27 and the wall surface. It is housed and cannot be visually recognized from the outside, and the appearance is improved.

図7は、壁材Wにあけられる壁孔H1 〜H3 の内径d1 〜d3 によって、当該壁孔H1 〜H3 に挿入されるスペーサS1 の長さが異なることで、壁孔の内径が所定の範囲内であれば、同一のスペーサS1 により当該壁孔H1 〜H3 の環状隙間K1 〜K3 を閉塞可能であることを示している。なお、スペーサS1 に対応する壁孔H1 の内径は、(d1)であって各壁孔H1 〜H3 の内径d1 〜d3 は、(d3 >d1 >d2 )の関係を有している。即ち、壁孔H1(H2,H3)の内径d1(d2,d3)が小さい程、環状隙間K1(K2,K3)が小さくなって、壁孔H1(H2,H3)に対するスペーサS1 の挿入長は短くなるが、複数の環状突出部4のうち、壁孔H1(H2,H3)の内径に対応したいずれかが、その内周面33に弾接することで、壁孔H1(H2,H3)に対してスペーサS1 が保持された状態で、環状隙間K1(K2,K3)が閉塞される。また、図 7(a)は、壁孔H2 の内径が、スペーサS1 の対応する壁孔H1 の内径d1 よりも小さいために、壁孔H2 に対するスペーサS1 の挿入長が短くて、その大径側の未挿入部が前記化粧リング27と干渉してしまうため、図8(a)に示されるように、大径側の2つの分割部2を環状凹溝1の部分で切断して、全長を半減させた例である。なお、図8(a)において、S1'は、切除された側のスペーサを示す。 7, the inner diameter d 1 to d 3 of wall holes H 1 to H 3 to be opened in the wall material W, that the length of the spacer S 1 to be inserted into the wall hole H 1 to H 3 are different, the walls If the inner diameter of the hole is within a predetermined range, the same spacer S 1 indicates that the annular gaps K 1 to K 3 of the wall holes H 1 to H 3 can be closed. The inner diameter of the wall hole H 1 corresponding to the spacer S 1 is (d 1 ), and the inner diameters d 1 to d 3 of the wall holes H 1 to H 3 are (d 3 > d 1 > d 2 ). Have the relationship. That is, the smaller the inner diameter d 1 (d 2 , d 3 ) of the wall hole H 1 (H 2 , H 3 ), the smaller the annular gap K 1 (K 2 , K 3 ) becomes, and the wall hole H 1 (H 2 , H 3 ), the insertion length of the spacer S 1 is shortened, but one of the plurality of annular protrusions 4 corresponding to the inner diameter of the wall hole H 1 (H 2 , H 3 ) By making elastic contact with 33, the annular gap K 1 (K 2 , K 3 ) is closed while the spacer S 1 is held with respect to the wall hole H 1 (H 2 , H 3 ). Further, FIG. 7 (a), the inside diameter of the wall hole H 2 is the smaller than the inner diameter d 1 of the corresponding wall hole H 1 of the spacer S 1, short insertion length of the spacer S 1 for wall hole H 2 Then, since the non-inserted portion on the large diameter side interferes with the decorative ring 27, as shown in FIG. 8A, the two divided portions 2 on the large diameter side are formed at the annular groove 1 portion. This is an example in which the entire length is cut by half. In FIG. 8A, S 1 ′ indicates the spacer on the cut side.

また、スペーサS1 は、図8(b)で示されるように、第1切割部9で切り割って、中空部7’の内径を大きくすることで、対応する外径D1 (図6参照)の延長接続管(水栓接続部)P0 よりも大きな外径(D2)の水栓接続部に対応可能である。即ち、図9及び図10に示されるように、外径(D2)の水栓接続部28を備えた水栓継手C2 において、当該水栓接続部28が壁孔H4 と同心状態で挿入された状態において、壁表から、第1切割部9で切り割られたスペーサS1 を壁孔H1 の環状隙間K4 に挿入すると、当該スペーサS1 は、水栓接続部28の外径(D2)に対応した量だけ切割部分が拡開されることで、中空部7’の内径が大きくなって、対応外径(D1)よりも大きな外径(D2)の水栓接続部28の外周面に嵌め込まれると共に、複数の環状突出部4が壁孔H4 の内周面に弾性変形して密着する。これにより、周方向の一部にスペーサS1 が存在しない開口部29が発生することで、壁孔H4 の環状隙間K1 の周方向の一部が未閉塞のままであるが、当該スペーサS1 は、壁孔H4 の内周面33に抜け出ることなく保持される。また、軸方向に沿った切り割りを容易にするための第1切割部9の部分で切り割って開口部29を形成することなく、予め切り割られた構造にしておいてもよい。なお、開口部29が壁孔H4 の上部に配置されるように、当該壁孔H4 の環状隙間K1'に対して周方向の一部に開口部29を有するスペーサS1 を圧入すると、当該スペーサS1 に対して負荷を作用する部分の全ては、壁孔H4 の内周面に密着しているため、当該水栓Vのがたつきを一層効果的に防止できる。 Further, as shown in FIG. 8B, the spacer S 1 is cut by the first cutting portion 9 to increase the inner diameter of the hollow portion 7 ′, thereby corresponding outer diameter D 1 (see FIG. 6). It is possible to cope with a faucet connection portion having an outer diameter (D 2 ) larger than the extension connection pipe (faucet connection portion) P 0 . That is, as shown in FIGS. 9 and 10, in the faucet joint C 2 provided with the faucet connection portion 28 having the outer diameter (D 2 ), the faucet connection portion 28 is concentric with the wall hole H 4. In the inserted state, when the spacer S 1 cut by the first cut portion 9 is inserted into the annular gap K 4 of the wall hole H 1 from the wall surface, the spacer S 1 is attached to the outside of the faucet connection portion 28. By expanding the cut portion by an amount corresponding to the diameter (D 2 ), the inner diameter of the hollow portion 7 ′ increases, and the faucet having an outer diameter (D 2 ) larger than the corresponding outer diameter (D 1 ) together are fitted into the outer peripheral surface of the connecting portion 28, a plurality of annular projection 4 is in close contact is elastically deformed to the inner peripheral surface of the wall hole H 4. As a result, the opening 29 where the spacer S 1 does not exist in a part in the circumferential direction is generated, so that a part in the circumferential direction of the annular gap K 1 of the wall hole H 4 remains unclosed. S 1 is held without slipping out to the inner peripheral surface 33 of the wall hole H 4 . In addition, the first cut portion 9 for facilitating cutting along the axial direction may be cut in advance without forming the opening 29 by cutting. In addition, as the opening 29 is disposed on top of the wall holes H 4, when press-fitting the spacer S 1 having an opening 29 in a part of the circumferential direction with respect to the wall hole H annular clearance K 1 of 4 ' Since all the portions that act on the spacer S 1 are in close contact with the inner peripheral surface of the wall hole H 4 , rattling of the faucet V can be more effectively prevented.

図11には、壁孔H4 に対して水栓継手C2 の水栓接続部28が偏芯して挿入された状態において、第1切割部9で切り割られたスペーサS1 により、環状隙間K4 が閉塞される構造を示している。なお、図11(b)において、J1 ,J2 は、それぞれ壁孔H4 及び水栓継手C2 の水栓接続部28の中心(軸心)を示す。水栓継手C2 の水栓接続部28の外径は(D2 )〔>D1 〕であるため、スペーサS1 は、第1切割部9で切り割られて、周方向の一部に中空部7’が形成された状態で、水栓継手C2 の水栓接続部28の外側に嵌め込まれて、環状隙間K1'が閉塞されている。即ち、水栓継手C2 の水栓接続部28は、壁孔H4 に対して偏芯配置されて、壁孔H4 を中心J1 で上下に二分した場合において、スペーサS1 の環状突出部4の変形量は、下半分の方が上半分よりも大きくなった状態で、環状隙間K4 が閉塞されている。そして、上記した偏芯量が一定量を超えて大きくなると、スペーサS1 の周方向の一部に開口部29を形成しないと、壁孔H4 の環状隙間K4 にスペーサS1 を圧入できなくなり、この場合において、当該開口部29が有効に作用する。 In FIG. 11, in a state where the faucet connection portion 28 of the faucet joint C 2 is eccentrically inserted with respect to the wall hole H 4 , the spacer S 1 cut by the first cut portion 9 causes an annular shape. A structure in which the gap K 4 is closed is shown. In FIG. 11B, J 1 and J 2 indicate the center (axial center) of the faucet connection portion 28 of the wall hole H 4 and the faucet joint C 2 , respectively. Since the outer diameter of the faucet connection portion 28 of the faucet joint C 2 is (D 2 ) [> D 1 ], the spacer S 1 is cut by the first cut portion 9 and is partly in the circumferential direction. In a state where the hollow portion 7 ′ is formed, the annular gap K 1 ′ is closed by being fitted to the outside of the faucet connection portion 28 of the faucet joint C 2 . That is, water faucet fittings C 2 faucet connecting portion 28 is eccentric positioned with respect to wall holes H 4, in the case where the divided down the center J 1 the wall holes H 4, an annular projection of the spacer S 1 deformation of the parts 4, with the direction of the lower half is greater than the upper half, the annular gap K 4 is closed. When the eccentric amount increases beyond a certain amount, the spacer S 1 can be press-fitted into the annular gap K 4 of the wall hole H 4 unless the opening 29 is formed in a part of the circumferential direction of the spacer S 1. In this case, the opening 29 works effectively.

また、上記配管例では、水栓継手C1 が壁裏において壁材Wから離間して配置されるために、水栓接続部21を壁孔H1 の部分まで到達させるために延長接続管P0 を使用しているが、図12及び図13に示される配管例では、横材32が壁材Wの裏面に接した状態で配置されているため、水栓継手C1 の水栓接続部21を壁孔H5 に直接に挿入できる構造である。L字形の水栓継手C1 は、水栓接続部21と管接続部34とを備え、L字形のブラケット31を介して周辺の部材に固定され、図4に示されるように、ブラケット31の一方の板部31aは、複数のボルト35を介して水栓継手C1 の背面側に固定され、他方の板部31bは、同じく複数本のボルト36を介して横材32に固定される。ブラケット31の板部31bの先端部は、水栓接続部21の基端部まで達していて、当該基端部に設けられた3つの突起部37a,37b,37cのいずれかに当接させて、水栓継手C1 の固定状態を安定化させている。図3及び図11の配管例では、給水管P1 が垂直配管されるため、ブラケット31の板部31bは、いずれも水栓接続部21の上面部に設けられた突起部37aに当接している。残りの2つの突起部37b,37cは、水栓接続部21の両側面部に対向して形成されて、給水管P1 が水平配管される場合において、ブラケット31の板部31bを当接させるのに使用される。このため、計3つの突起部37a,37b,37cは、水栓継手C1 の水栓接続部21の基端部の外周面に互いに位相が90°だけずれて配置されている。 Further, in the above piping example, since the faucet joint C 1 is arranged behind the wall material W on the back of the wall, the extension connecting pipe P is used to reach the faucet connection portion 21 to the wall hole H 1. In the piping examples shown in FIGS. 12 and 13, since the cross member 32 is arranged in contact with the back surface of the wall material W, the faucet connection portion of the faucet joint C 1 is used. In this structure, 21 can be directly inserted into the wall hole H 5 . The L-shaped water faucet joint C 1 includes a water faucet connection portion 21 and a pipe connection portion 34, and is fixed to peripheral members via an L-shaped bracket 31. As shown in FIG. One plate portion 31 a is fixed to the back side of the faucet joint C 1 through a plurality of bolts 35, and the other plate portion 31 b is fixed to the cross member 32 through a plurality of bolts 36. The distal end portion of the plate portion 31b of the bracket 31 reaches the proximal end portion of the faucet connecting portion 21, and is brought into contact with any one of the three projecting portions 37a, 37b, 37c provided on the proximal end portion. The fixed state of the faucet joint C 1 is stabilized. In the piping examples of FIGS. 3 and 11, since the water supply pipe P 1 is vertically piped, the plate portion 31 b of the bracket 31 is in contact with the protruding portion 37 a provided on the upper surface portion of the faucet connection portion 21. Yes. The remaining two projections 37b, 37c are the formed to face the both side surfaces of the faucet connecting portion 21, when the water supply pipe P 1 is a horizontal pipe, it is brought into contact with the plate portion 31b of the bracket 31 Used for. Therefore, a total of three protrusions 37a, 37b, 37c are phases on the outer peripheral surface of the proximal end portion of the faucet joint C 1 faucet connecting portion 21 is disposed offset by 90 °.

そして、水栓継手C1 の水栓接続部21が壁孔H5 に挿入されて、当該水栓接続部21の外周面と壁孔H5 の内周面33とで形成された環状隙間K5 をスペーサS1 で閉塞するには、以下のようにして行う。即ち、スペーサS1 を第1切割部9の部分で切り割って、中空部7’の内径を大きくすると共に、第2切割部11を切り割って、当該第2切割部11の側を上方に向けた状態で、当該スペーサS1 を壁表から前記水栓継手C1 の水栓接続部21の外側に嵌め込むと、スペーサS1 の開口部29を除く部分において、環状突出部4が弾性変形により壁表の側に傾動されて、壁孔H5 の内周面33に弾接することで、前記環状隙間K5 が閉塞される。 The faucet connecting portion 21 of the water faucet joint C 1 is inserted into the wall hole H 5, the outer peripheral surface and the wall hole H annular gap K formed between the inner circumferential surface 33 of 5 of the faucet connecting portion 21 To close 5 with the spacer S 1 , the following procedure is performed. That is, the spacer S 1 is cut at the portion of the first cut portion 9 to increase the inner diameter of the hollow portion 7 ′, and the second cut portion 11 is cut so that the second cut portion 11 side faces upward. When the spacer S 1 is fitted to the outside of the faucet connecting portion 21 of the faucet joint C 1 from the wall surface in the state of being directed, the annular protrusion 4 is elastic in the portion excluding the opening 29 of the spacer S 1. The annular gap K 5 is closed by being tilted to the wall surface side by deformation and elastically contacting the inner peripheral surface 33 of the wall hole H 5 .

環状隙間K5 を閉塞しているスペーサS1 の奥側の小径部においては、図12及び図13に詳細に図示されているように、スペーサS1 における第2切割部11で切り割られた部分は、水栓継手C1 の水栓接続部21とブラケット31の板部31bとの隙間が入り込んだ状態で、当該水栓接続部21の上部に設けられた突起部37aにより両側に押し拡げられて、当該突起部37aを両側から挟んだ状態に配置される。また、スペーサS1 の奥側の小径部における各突起部37b,37cの部分においては、当該各突起部37b,37cに乗り上げた状態となって配置される。 As shown in detail in FIGS. 12 and 13, the small-diameter portion on the back side of the spacer S 1 closing the annular gap K 5 is cut by the second cut portion 11 in the spacer S 1 . moiety is a gap has entered a state of the plate portion 31b of the faucet connecting portion 21 of the water faucet joint C 1 and the bracket 31, press on opposite sides by projections 37a provided on the upper portion of the faucet connecting portion 21 expanded Thus, the protrusion 37a is disposed in a state sandwiched from both sides. Further, the protrusions 37b of the small diameter portion of the inner side of the spacer S 1, in the portion of the 37c, the respective protrusions 37b, being disposed in a state of riding on 37c.

次に、図14を参照して、参考例1のスペーサS2 について、上記したスペーサS1 と異なる部分についてのみ説明する。参考例1のスペーサS2 は、前記スペーサS1 に対してテーパー円筒部8’の外周面に形成された傾斜突条部41の形状のみが異なる。即ち、テーパー円筒部8’の外周面には、複数本の傾斜突条部41が周方向に一定間隔をおいてスペーサS2 の軸心J1 に対して角度(θ)だけ傾斜して一体に設けられている。傾斜突条部41の突出長は、全長に亘って一定であるが、当該傾斜突条部41が一体に設けられているテーパー円筒部8’の外径が軸方向に沿ってテーパー状に変化しているため、傾斜突状部41の先端部の外径は、軸方向に沿った一端から他端に向けて直線的に変化している。参考例1では、複数本の傾斜突条部41が外径調整部を構成している。
(Reference Example 1)
Next, with reference to FIG. 14, only the portion different from the spacer S 1 described above will be described for the spacer S 2 of Reference Example 1 . The spacer S 2 of Reference Example 1 differs from the spacer S 1 only in the shape of the inclined ridge portion 41 formed on the outer peripheral surface of the tapered cylindrical portion 8 ′. That is, on the outer peripheral surface of the tapered cylindrical portion 8 ′, a plurality of inclined protrusions 41 are integrally inclined at an angle (θ) with respect to the axis J 1 of the spacer S 2 at regular intervals in the circumferential direction. Is provided. The protruding length of the inclined ridge portion 41 is constant over the entire length, but the outer diameter of the tapered cylindrical portion 8 ′ in which the inclined ridge portion 41 is provided integrally changes in a tapered shape along the axial direction. For this reason, the outer diameter of the tip of the inclined protrusion 41 changes linearly from one end to the other end along the axial direction. In Reference Example 1, the inclined ridges 41 of the plurality of constitute the outer diameter adjustment unit.

このため、壁孔H1 に挿入された水栓継手C1 の延長接続管P0 の外周面と、当該壁孔H1 の内周面との間の環状隙間K1 に壁表からスペーサS2 を圧入すると、傾斜突条部41がスペーサS2 の軸心J1 に対して傾斜しているため、当該傾斜突条部41の先端部が常に一方側に傾動されて、壁孔H1 の内径d1 に対応した長さだけスペーサS2 が当該壁孔H1 に挿入された状態で、当該壁孔H1 の内周面33に密着する。 Therefore, the outer peripheral surface of the extension connecting pipe P 0 faucet joint C 1 inserted into wall holes H 1, the spacer S from the wall table annular gap K 1 between the inner peripheral surface of the wall hole H 1 When 2 is press-fitted, since the inclined ridge 41 is inclined with respect to the axis J 1 of the spacer S 2 , the tip end of the inclined ridge 41 is always inclined to one side, and the wall hole H 1. The spacer S 2 is in close contact with the inner peripheral surface 33 of the wall hole H 1 in a state where the spacer S 2 is inserted into the wall hole H 1 by a length corresponding to the inner diameter d 1 of the wall hole H 1 .

また、隣接する傾斜突条部41の間はテーパー円筒部8のみが存在しているため、スペーサS2 の周方向の一部に開口部を形成して、対応外径よりも大きな外径の水栓継手の水栓接続部に嵌め込むためには、隣接する傾斜突条部41の間のテーパー円筒部8を当該傾斜突条部41に沿って切断すればよい。当該切断は、テーパー円筒部8が薄肉構造であるため容易である。 Further, between the inclined ridges 41 adjacent because only the tapered cylindrical portion 8 is present, to form an opening in a part of the circumferential spacer S 2, the outer diameter larger than the corresponding outer diameter In order to fit into the faucet connection portion of the faucet joint, the tapered cylindrical portion 8 between the adjacent inclined ridge portions 41 may be cut along the inclined ridge portion 41. The cutting is easy because the tapered cylindrical portion 8 has a thin structure.

(参考例2)
次に、図15を参照して、参考例2のスペーサS3 について、参考例1のスペーサS2 は、軸心J1 に対して傾斜した状態でテーパー円筒部8’の外周に一体に設けられた複数の傾斜突条部41が外径調整部を構成しているのに対して、参考例2のスペーサS3 は、テーパー円筒部8”の外側に、当該テーパー円筒部8”の小径側から大径側に向けて高さが徐々に高くなった断面三角形状の山部42aを有する螺旋突条部42が一体に設けられた構成である。スペーサS3 では、螺旋突条部42が外径調整部を構成している。また、スペーサS3 には、スペーサS1 と同様に、第1及び第2の各切割部9,11が設けられている。
(Reference Example 2)
Next, referring to FIG. 15, the spacer S 3 of Reference Example 2, the spacer S 2 of Reference Example 1, provided integrally with the outer periphery of the tapered cylindrical portion 8 'in a state inclined with respect to the axial center J 1 In contrast to the plurality of inclined ridge portions 41 constituting the outer diameter adjusting portion, the spacer S 3 of Reference Example 2 has a small diameter of the tapered cylindrical portion 8 ″ outside the tapered cylindrical portion 8 ″. A spiral protrusion 42 having a triangular section 42a having a triangular cross section whose height gradually increases from the side toward the large diameter side is integrally provided. In the spacer S 3 , the spiral protrusion 42 constitutes an outer diameter adjusting portion. The spacer S 3 is provided with first and second cut portions 9 and 11 as in the case of the spacer S 1 .

図16に示される実施例のスペーサS4 は、実施例1のスペーサS1 において、水栓継手C1 の延長接続管P0 又は水栓接続部21に嵌め込まれる中空部7”の断面形状が異なるのみである。即ち、実施例1のスペーサS1 では、中空部7には、前記延長接続管P0 又は水栓接続部21の外側に嵌め込まれるスプライン状の複数本の支持突条6が周方向に一定間隔をおいて設けられている。これに対して実施例のスペーサS4 では、中空部7”の横断面形状を正八角形にして、延長接続管P0 又は水栓接続部21に対する嵌め込みを容易にしてある。 The spacer S 4 of the second embodiment shown in FIG. 16 is the same as the spacer S 1 of the first embodiment in the cross-sectional shape of the hollow portion 7 ″ fitted into the extension connecting pipe P 0 or the faucet connecting portion 21 of the faucet joint C 1. In other words, in the spacer S 1 of the first embodiment, the hollow portion 7 has a plurality of spline-like support protrusions 6 fitted outside the extension connection pipe P 0 or the faucet connection portion 21. On the other hand, in the spacer S 4 of the second embodiment, the cross section of the hollow portion 7 ″ is a regular octagon, and the extension connection pipe P 0 or the faucet connection is provided. The fitting to the portion 21 is facilitated.

(参考例3)
また、実施例1,2及び参考例1,2のスペーサS1 〜S4 は、いずれも筒状に形成されているが、図17に示されるようにスペーサS5 のように、板状のものを巻回させて筒状を形成する構成であってもよい。即ち、板状のスペーサS5'の原形状は、図17(a)に示されるように、細長比の大きな長方形の板状であって、その肉厚は、短辺の方向に沿って漸次変化する形状である。板状のスペーサS5'を巻回させた円筒状のスペーサS5 では、その外径が軸方向に沿ってテーパー状に変化している外周部が外径調整部となっている。スペーサS5 は、原形状が板状であるために、水栓継手の水栓接続部の異なる外径に対応した巻回状態を実現できて、水栓接続部の外径の異なる水栓継手に対応できる利点がある。
(Reference Example 3)
The spacer S 1 to S 4 of Examples 1 and 2 and Reference Examples 1 and 2, although both formed in a cylindrical shape, like a spacer S 5 as shown in FIG. 17, plate-shaped The structure which winds things and forms a cylinder shape may be sufficient. That is, the original shape of the plate-like spacer S 5 ′ is a rectangular plate shape having a large slenderness ratio as shown in FIG. 17A, and its thickness gradually increases along the direction of the short side. It is a changing shape. In the cylindrical spacer S 5 which is wound spacers S 5 'plate-shaped, outer peripheral portion of the outer diameter is changed in a tapered shape along the axial direction is the outside diameter adjuster. Since the original shape of the spacer S 5 is a plate shape, it is possible to realize a winding state corresponding to different outer diameters of the faucet connection portions of the faucet joint, and faucet joints having different outer diameters of the faucet connection portions. There is an advantage that can be accommodated.
