以下、本発明の実施の形態について図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１及び図２に示すように、本発明の一実施の形態に係る給水栓１は、例えば埋め込み水栓として用いられるものであり、継手部２及び流量調整部材（例えばハンドル）３が、正面視略矩形状のカバー４の表側（外側）に露出（突出）した状態で設けられる。 As shown in FIGS. 1 and 2, a water faucet 1 according to an embodiment of the present invention is used as, for example, an embedded water faucet. It is provided in a state of being exposed (protruded) on the front side (outside) of the cover 4 having a substantially rectangular shape.

継手部２には、例えば、図１に示す給水対象（図示例は洗濯機）Ｔに繋がった給水ホースＨの上流端に設けられた継手部材Ｃが着脱自在に接続される。ここで、継手部材Ｃには、継手部２のフランジ部材５に係脱自在に係止する係止部Ｃ１が設けられている（図３（Ａ）及び（Ｂ）参照）。そして、継手部２に継手部材Ｃを接続すると、継手部２のストップ弁（緊急止水弁）６が継手部材Ｃに押されて上流側に移動し、開弁状態となって継手部２から給水ホースＨ側への給水が可能となり、継手部２に対する継手部材Ｃの接続が解除されると、ストップ弁６が元の位置に戻り、閉弁状態となる。このような機能を持つストップ弁６の構成は公知であり、そのより詳しい説明は省略する。 For example, a joint member C provided at an upstream end of a water supply hose H connected to a water supply target (in the illustrated example, a washing machine) T illustrated in FIG. 1 is detachably connected to the joint portion 2. Here, the joint member C is provided with a locking portion C1 that is detachably locked to the flange member 5 of the joint portion 2 (see FIGS. 3A and 3B). Then, when the joint member C is connected to the joint portion 2, the stop valve (emergency stop valve) 6 of the joint portion 2 is pushed by the joint member C and moves upstream, and enters the valve opening state from the joint portion 2. When water supply to the water supply hose H side becomes possible and the connection of the joint member C to the joint portion 2 is released, the stop valve 6 returns to the original position and the valve is closed. The structure of the stop valve 6 having such a function is known, and a detailed description thereof will be omitted.

流量調整部材３は、水栓本体７の下流側に設けられる継手部２から給水ホースＨ側への給水流量を調整するためにカバー４の表側から操作されるものである。本形態の流量調整部材３は、図３（Ａ）及び（Ｂ）、図４に示すように、水栓本体７の開口部８に装着されて水栓本体７に接続される筒状部材９に取り付けられる（接続される）。 The flow rate adjusting member 3 is operated from the front side of the cover 4 in order to adjust the water supply flow rate from the joint portion 2 provided on the downstream side of the faucet body 7 to the water supply hose H side. As shown in FIGS. 3A and 3B and FIG. 4, the flow rate adjusting member 3 of this embodiment is a cylindrical member 9 that is attached to the opening 8 of the faucet body 7 and connected to the faucet body 7. Attached (connected).

ここで、水栓本体７の接続部７a （図５（Ａ）参照）には、水栓本体７を介して給水ホースＨ側へ給水するための給水管（図示していない）が接続されるが、この接続は図４に示すようなストレート状の配管接続部材１０を介して行われてもよいし、水栓本体７（接続部７ａ）に対して軸回りに３６０°回転自在に構成されたエルボである配管接続部材（図示していない）を介して行われてもよい。後者の場合には、給水管が接続される配管接続部材が水栓本体７に対して回転自在となるので、斯かる給水管が床下から配管された場合のみならず、例えば天井から配管された場合にも対応が容易となる。 Here, a water supply pipe (not shown) for supplying water to the water supply hose H side is connected to the connection portion 7a (see FIG. 5A) of the water faucet body 7 through the water faucet body 7. However, this connection may be made via a straight pipe connecting member 10 as shown in FIG. 4, or is configured to be rotatable 360 ° around the axis with respect to the faucet body 7 (connecting portion 7a). It may be performed through a pipe connecting member (not shown) which is an elbow. In the latter case, since the pipe connecting member to which the water supply pipe is connected is rotatable with respect to the faucet body 7, not only when the water supply pipe is piped from under the floor, but also from the ceiling, for example. It becomes easy to cope with the case.

一方、筒状部材９は、水栓本体７内に螺合する状態で挿入される挿入部１１を有し、筒状部材９自身の軸まわりの回動に伴って水栓本体７内に進退し、水栓本体７の内壁に設けられた弁座部１２に対して近接及び離間するように、水栓本体７（開口部８）内に設けられた雌ねじと挿入部１１に設けられた雄ねじとからなる螺合部１３が設けられている（図５（Ａ）参照）。 On the other hand, the cylindrical member 9 has an insertion portion 11 inserted in a state of being screwed into the faucet body 7, and advances and retracts into the faucet body 7 as the cylindrical member 9 rotates about its own axis. A female screw provided in the faucet body 7 (opening 8) and a male screw provided in the insertion portion 11 so as to approach and separate from the valve seat portion 12 provided on the inner wall of the faucet body 7. The screwing part 13 which consists of is provided (refer FIG. 5 (A)).

挿入部１１の一端（先端）側には弁座部１２に密着当接可能な環状の弁体部（本実施形態ではパッキン）１４（図５（Ａ）参照）が装着されている。この弁体部１４は、水栓本体７内への筒状部材９の進退により、弁座部１２に当接し弁座部１２によって挿入部１１の先端側が閉塞される閉弁状態と、弁座部１２から離間した開弁状態とになる。すなわち、挿入部１１が開弁状態にあるとき（図７参照）には、接続部７ａから水栓本体７内に至った水を、弁座部１２と弁体部１４との隙間から挿入部１１（弁体部１４）内、さらには継手部２側へと向かわせる給水が可能となるが、弁体部１４が弁座部１２に密着当接する閉弁状態では（図５（Ａ）参照）、斯かる給水が不可能となる。 An annular valve body portion (packing in this embodiment) 14 (see FIG. 5A) that can come into close contact with the valve seat portion 12 is attached to one end (tip) side of the insertion portion 11. The valve body portion 14 is in a closed state in which the distal end side of the insertion portion 11 is closed by the valve seat portion 12 by contact with the valve seat portion 12 by the advancement and retraction of the tubular member 9 into the faucet body 7. The valve is opened away from the portion 12. That is, when the insertion portion 11 is in the valve open state (see FIG. 7), the water that has reached the faucet body 7 from the connecting portion 7a is inserted into the insertion portion through the gap between the valve seat portion 12 and the valve body portion 14. 11 (valve body portion 14), and further, water can be supplied to the joint portion 2 side. However, when the valve body portion 14 is in close contact with the valve seat portion 12 (see FIG. 5A). ), Such water supply becomes impossible.

図５（Ａ）に示すように、挿入部１１内における逆止弁１５の上流側には、挿入部１１内に形成される流路を狭め、水圧を下げるための減圧板１６が設けられている。尚、減圧板１６は、中央部に貫通孔が形成された板状の部材である。 As shown in FIG. 5A, a pressure reducing plate 16 is provided on the upstream side of the check valve 15 in the insertion portion 11 to narrow the flow path formed in the insertion portion 11 and reduce the water pressure. Yes. The decompression plate 16 is a plate-like member having a through hole formed at the center.

ここで、挿入部１１が水栓本体７の開口部８から抜けてしまうことは、水栓本体７の開口部８の周縁に固定される抜け止め片１７によって防止される（図１２〜図１４参照）。図示例では、抜け止め片１７はねじ１８により水栓本体７に固定される。 Here, the insertion portion 11 is prevented from coming off from the opening 8 of the faucet body 7 by a retaining piece 17 fixed to the periphery of the opening 8 of the faucet body 7 (FIGS. 12 to 14). reference). In the illustrated example, the retaining piece 17 is fixed to the faucet body 7 by a screw 18.

また、挿入部１１と水栓本体７の内壁との間からの水漏れは、挿入部１１の外周面に設けられたシール部材（図示例はＯリング）１９により防止される。 Further, water leakage from between the insertion portion 11 and the inner wall of the faucet body 7 is prevented by a seal member (O-ring in the illustrated example) 19 provided on the outer peripheral surface of the insertion portion 11.

そして、図５（Ａ）に示すように、筒状部材９の他端（前端）側の内外に継手部２及び流量調整部材３が接続される。本実施形態では、筒状部材９に対する継手部２の接続は螺着により行われる。また、筒状部材９に対する流量調整部材３の接続は、筒状部材９において水栓本体７内に挿入されない部分の外周側に設けられたアウターセレーション２０ａと、流量調整部材３に設けられたインナーセレーション２０ｂとからなるセレーション嵌合部２０により行われる。 As shown in FIG. 5A, the joint portion 2 and the flow rate adjusting member 3 are connected to the inside and outside of the cylindrical member 9 on the other end (front end) side. In this embodiment, connection of the joint part 2 with respect to the cylindrical member 9 is performed by screwing. Further, the connection of the flow rate adjusting member 3 to the cylindrical member 9 is performed by connecting the outer serration 20a provided on the outer peripheral side of the portion not inserted into the faucet body 7 in the cylindrical member 9 and the inner provided on the flow rate adjusting member 3. This is performed by the serration fitting portion 20 including the serration 20b.

従って、筒状部材９は流量調整部材３の回動操作に伴って回動するのであり、流量調整部材３が図２に示す位置にあるときには、筒状部材９は閉弁状態（図５（Ａ）参照）となっており、この位置にある流量調整部材３を図２の矢印イ方向に回動操作するにつれて、筒状部材９の弁体部１４と弁座部１２とで構成される弁の開度は大きくなり、継手部２から給水ホースＨ側への給水流量も大となる。 Accordingly, the cylindrical member 9 is rotated in accordance with the rotation operation of the flow rate adjusting member 3, and when the flow rate adjusting member 3 is in the position shown in FIG. As shown in FIG. 2A, the flow rate adjusting member 3 located at this position is rotated in the direction of arrow A in FIG. 2 and is constituted by the valve body portion 14 and the valve seat portion 12 of the cylindrical member 9. The opening degree of the valve increases, and the water supply flow rate from the joint portion 2 to the water supply hose H side also increases.

そして、水栓本体７は、図４、図６（Ａ）に示すように、壁（ボード）Ｗの裏側に設置（固定配置）された略鉛直方向に延びる間柱Ｍに対して、その前端が間柱Ｍの前面（あるいは壁Ｗの背面）に沿うように位置決めされた状態で取り付けられる金属製（例えば鉄製）の保持具２１によって保持される。 The faucet body 7 has a front end that is opposite to a substantially vertical pillar M that is installed (fixedly arranged) on the back side of the wall (board) W, as shown in FIGS. 4 and 6A. It is hold | maintained by the metal (for example, iron) holder 21 attached in the state positioned along the front surface of the stud M (or the back surface of the wall W).

保持具２１は、図４、図５（Ａ）、図６（Ａ）、図９（Ａ）〜（Ｇ）に示すように、略鉛直方向かつ壁Ｗと略直交する方向に延びる第１取付け面部２２と、この第１取付け面部２２の上部に連設され略水平方向に延びる第２取付け面部２３と、第１取付け面部２２の前部に連設され略鉛直方向かつ壁Ｗと略平行に延びる保持面部２４とを有し、例えば冷間圧延鋼板（ＳＰＣＣ）パンチや曲げ加工に適した構成となっている。また、第１取付け面部２２と第２取付け面部２３との境界となる曲げ部分と、第１取付け面部２２と保持面部２４との境界となる曲げ部分とには、それぞれビード加工が施されている。 As shown in FIGS. 4, 5 (A), 6 (A), and 9 (A) to (G), the holding tool 21 is a first attachment that extends in a substantially vertical direction and a direction substantially orthogonal to the wall W. A surface portion 22, a second mounting surface portion 23 that is connected to the upper portion of the first mounting surface portion 22 and extends in a substantially horizontal direction, and a front portion of the first mounting surface portion 22 that is connected in a substantially vertical direction and substantially parallel to the wall W. For example, it has a configuration suitable for cold rolled steel plate (SPCC) punching or bending. In addition, bead processing is performed on the bent portion serving as the boundary between the first mounting surface portion 22 and the second mounting surface portion 23 and the bent portion serving as the boundary between the first mounting surface portion 22 and the holding surface portion 24. .

そして、第１、第２取付け面部２２，２３にはそれぞれ、ねじ２５によるねじ止め用の長孔２２ａ，２３ａが例えば複数（図示例では二つずつ）設けられ、保持面部２４には、接続具２６に挿通される雌ねじ部分２４ａが例えば複数（図示例では二つ）設けられている。さらに、第１、第２取付け面部２２，２３の前部にはそれぞれ、保持面部２４よりも前側に突出する位置決め用の突出部分２７が設けられている。 Each of the first and second mounting surface portions 22 and 23 is provided with a plurality of, for example, two (two in the illustrated example) long holes 22a and 23a for screwing with screws 25. For example, a plurality (two in the illustrated example) of female screw portions 24 a inserted through the inner wall 26 are provided. Further, a positioning protruding portion 27 that protrudes to the front side of the holding surface portion 24 is provided at the front portion of the first and second mounting surface portions 22 and 23.

接続具２６は、水栓本体７に設けられた挿通孔７ｂ（図４参照）と保持具２１の保持面部２４の雌ねじ部分２４ａとにわたって差し込まれ（螺着し）両者７，２１を接続するように構成されている。尚、本形態の接続具２６は座金組み込みねじ（所謂セムスねじ）であるが、図４では、接続具２６の座金の図示を省略してある。 The connection tool 26 is inserted (screwed) across the insertion hole 7b (see FIG. 4) provided in the faucet body 7 and the female screw portion 24a of the holding surface portion 24 of the holder 21 so as to connect the two and 21. It is configured. In addition, although the connection tool 26 of this form is a washer built-in screw (so-called Sems screw), in FIG. 4, illustration of the washer of the connection tool 26 is omitted.

さらに、図４に示すように、接続具２６における水栓本体７に差し込まれる部分と保持具２１に差し込まれる部分との間の部分に挿通された状態となるように合成樹脂（例えばＰＯＭ）製のスペーサ２８が装着される。そして、このスペーサ２８は着脱自在であって、図６（Ｂ）に示すように装着した状態にも、図６（Ａ）に示すように外した状態にもすることができる。 Further, as shown in FIG. 4, a synthetic resin (for example, POM) is used so as to be inserted into a portion between the portion inserted into the faucet body 7 and the portion inserted into the holder 21 in the connection tool 26. A spacer 28 is attached. The spacer 28 is detachable and can be attached as shown in FIG. 6 (B) or removed as shown in FIG. 6 (A).

ここで、本形態では、相互に長さＬ（図６（Ｂ）参照）が異なる複数種（例えば４種）のスペーサ２８から任意の長さＬを有するスペーサ２８が選択されて用いられ、このようにして装着されるスペーサ２８の長さ（保持具２１に当接する部位から水栓本体７に当接する部位までの長さ）が変更されたり、斯かるスペーサ２８が着脱されたりすることによって、接続具２６において保持具２１に差し込まれる部分から水栓本体７に差し込まれる部分までの距離が変更され、水栓本体７の位置が壁Ｗの表裏方向に移動する（壁Ｗから水栓本体７までの距離も変更される）ことになる。 Here, in the present embodiment, a spacer 28 having an arbitrary length L is selected from a plurality of types (for example, four types) of spacers 28 having different lengths L (see FIG. 6B). By changing the length of the spacer 28 thus mounted (the length from the portion in contact with the holder 21 to the portion in contact with the faucet body 7) or by attaching or detaching the spacer 28, In the connection tool 26, the distance from the part inserted into the holding tool 21 to the part inserted into the faucet body 7 is changed, and the position of the faucet body 7 moves in the front and back direction of the wall W (from the wall W to the faucet body 7 Will also be changed).

尚、本形態では、長さが同一あるいは相互に異なる複数のスペーサ２８を適宜に組み合わせて用いるのであり、長さＬの範囲が３．０ｍｍ〜９．５ｍｍである４種類（３．０ｍｍ，４．０ｍｍ，７．０ｍｍ，９．５ｍｍ）のスペーサ２８が用意されている。すなわち、本形態では、壁Ｗの厚みが９．５ｍｍである場合（図５（Ａ）、図７参照）には図６（Ａ）に示すようにスペーサ２８を接続具２６に装着せず、壁Ｗの厚みが１２．５ｍｍである場合（図５（Ｂ）参照）には長さＬが３．０ｍｍのスペーサ２５を一つのみ接続具２６に装着する（図６（Ｂ）参照）。また、例えば、壁Ｗの厚みが２５ｍｍである場合には、長さＬが３．０ｍｍのスペーサ２８を二つと長さＬが９．５ｍｍのスペーサ２８を一つとを組み合わせて接続具２６に装着する。 In this embodiment, a plurality of spacers 28 having the same length or different from each other are used in appropriate combination, and four types (3.0 mm, 4 mm) in which the length L ranges from 3.0 mm to 9.5 mm. Spacers 28 of 0.0 mm, 7.0 mm, 9.5 mm) are prepared. That is, in this embodiment, when the thickness of the wall W is 9.5 mm (see FIGS. 5A and 7), the spacer 28 is not attached to the connection tool 26 as shown in FIG. When the thickness of the wall W is 12.5 mm (see FIG. 5B), only one spacer 25 having a length L of 3.0 mm is attached to the connector 26 (see FIG. 6B). For example, when the thickness of the wall W is 25 mm, two spacers 28 having a length L of 3.0 mm and one spacer 28 having a length L of 9.5 mm are combined and attached to the connection tool 26. To do.

本実施形態の保持具２１は、第１，第２取付け面部２２，２３の前部に設けられた突出部分２７の前縁が間柱Ｍの前面（あるいは壁Ｗの背面）に沿うように設置され、保持面部２４の前側（壁Ｗに近い側）に水栓本体７が接続されるので、保持面部２４は突出部分２７の前縁よりも所定間隔だけ壁Ｗから遠のくように構成されている。 The holder 21 of the present embodiment is installed such that the front edge of the protruding portion 27 provided at the front portion of the first and second mounting surface portions 22 and 23 is along the front surface of the stud M (or the back surface of the wall W). Since the faucet body 7 is connected to the front side (side closer to the wall W) of the holding surface portion 24, the holding surface portion 24 is configured to be farther from the wall W by a predetermined interval than the front edge of the protruding portion 27.

上記のように保持具２１、接続具２６を用い、さらに必要に応じてスペーサ２８を用いて間柱Ｍに固定される水栓本体７に対して、水栓本体７の開口部８に装着される筒状部材９の前部は、壁Ｗに設けられた例えば縦１００ｍｍ×横５０ｍｍの大きさを有する水栓取付け用の取付け孔Ｗａを抜けて壁Ｗの表側に突出する（図４参照）。そして、本形態では、カバー４は、カバー４に設けられた二つの挿通孔４ａ（図８参照）を挿通する二つの固定ねじ２９（図４参照）により水栓本体７に取り付けられ、これにより、カバー４は壁Ｗの表側において固定された状態となる。また、カバー４には、二つの固定ねじ２９を覆うようにキャップ３０（図４参照）が着脱自在に装着される。 As described above, the holder 21 and the connection tool 26 are used, and if necessary, the faucet body 7 fixed to the stud M using the spacer 28 is attached to the opening 8 of the faucet body 7. The front portion of the cylindrical member 9 protrudes to the front side of the wall W through a faucet mounting hole Wa having a size of, for example, 100 mm long × 50 mm wide provided on the wall W (see FIG. 4). In this embodiment, the cover 4 is attached to the faucet body 7 by two fixing screws 29 (see FIG. 4) that pass through the two insertion holes 4a (see FIG. 8) provided in the cover 4. The cover 4 is fixed on the front side of the wall W. A cap 30 (see FIG. 4) is detachably attached to the cover 4 so as to cover the two fixing screws 29.

そして、このカバー４の固定後に、カバー４に設けられ前方斜め下側に向いた筒状部４ｂから壁Ｗの表側に突出する筒状部材９のアウターセレーション２０ａに対して流量調整部材３のインナーセレーション２０ｂが嵌合され、流量調整部材３はカバー４によって保持される状態となる。すなわち、流量調整部材３の後部にはＯリング３ａ（図５（Ａ）参照）が装着され、このＯリング３ａは、カバー４の筒状部４ｂに設けられた複数（例えば８個）の爪４ｃにより挟持される（図４、図８参照）。尚、複数の爪４ｃは、全てが同一円周上にあるのではなく、図８に示すように、前側にずれた爪４ｃと後側にずれた爪４ｃとが周方向に交互に並ぶようにしてあり、前側に位置する複数の爪４ｃと後側に位置する複数の爪４ｃとでＯリング３ａを挟持可能としてある。 Then, after the cover 4 is fixed, the inner side of the flow rate adjusting member 3 with respect to the outer serration 20a of the cylindrical member 9 provided on the cover 4 and projecting to the front side of the wall W from the cylindrical portion 4b facing obliquely downward. The serration 20 b is fitted, and the flow rate adjusting member 3 is held by the cover 4. That is, an O-ring 3 a (see FIG. 5A) is attached to the rear portion of the flow rate adjusting member 3, and the O-ring 3 a has a plurality of (e.g., eight) claws provided on the cylindrical portion 4 b of the cover 4. 4c (see FIGS. 4 and 8). The plurality of claws 4c are not all on the same circumference. As shown in FIG. 8, the claws 4c shifted to the front side and the claws 4c shifted to the rear side are alternately arranged in the circumferential direction. The O-ring 3a can be held between the plurality of claws 4c located on the front side and the plurality of claws 4c located on the rear side.

このように、流量調整部材３はカバー４によって保持された状態で筒状部材９にセレーション嵌合するように構成されているので、流量調整部材３を回動操作したときに、筒状部材９は継手部２と共に軸方向に移動するが、流量調整部材３は回動のみして移動しないので、流量調整部材３の操作性は優れたものとなる。 Thus, since the flow rate adjusting member 3 is configured to be serrated and fitted to the cylindrical member 9 while being held by the cover 4, the cylindrical member 9 is operated when the flow rate adjusting member 3 is rotated. Moves in the axial direction together with the joint portion 2, but the flow rate adjusting member 3 only rotates and does not move, so that the operability of the flow rate adjusting member 3 is excellent.

一方、上述したカバー４の固定後に、壁Ｗの表側に突出する継手部２には、図１〜図３、図５（Ａ）に示すように、フランジ部材５が装着される。本形態のフランジ部材５には、その中央部から周縁部にかけて切り欠き孔（図示していない）が設けられ、この切り欠き孔において、フランジ部材５の中央部に位置する孔部分より周縁部に位置する孔部分の方が大きくなっている。そして、フランジ部材５の周縁部寄りの孔部分に継手部２を通した後、フランジ部材５をスライドさせ、フランジ部材５の中央部寄りの孔部分の内側に継手部２を移動させることにより、継手部２に対するフランジ部材５の装着が完了し、継手部２に対する給水ホースＨの接続が可能な状態となる。 On the other hand, the flange member 5 is attached to the joint portion 2 protruding to the front side of the wall W after the cover 4 is fixed, as shown in FIGS. The flange member 5 of this embodiment is provided with a notch hole (not shown) from the central part to the peripheral part. In this notch hole, the peripheral part is more than the hole part located at the central part of the flange member 5. The hole part located is larger. And after passing the joint part 2 through the hole part near the peripheral part of the flange member 5, the flange member 5 is slid, and the joint part 2 is moved to the inside of the hole part near the center part of the flange member 5, The attachment of the flange member 5 to the joint portion 2 is completed, and the water supply hose H can be connected to the joint portion 2.

上述のようにカバー４に流量調整部材３を保持させた後、カバー４の筒状部４ｂ（図４参照）から壁Ｗの表側に突出する継手部２にはフランジ部材５が装着され、これにより、継手部２に対する給水ホースＨの接続が可能となる。 After the flow rate adjusting member 3 is held by the cover 4 as described above, the flange member 5 is attached to the joint portion 2 protruding from the cylindrical portion 4b (see FIG. 4) of the cover 4 to the front side of the wall W. Thereby, connection of the water supply hose H with respect to the joint part 2 is attained.

上記のように構成した本実施の形態では、流量調整部材３に対する操作力（回動力）を弁（弁体部１４）に伝達するための構造がシンプルであり、このことは製造コストの低減に繋がる上、流量調整部材３をカバー４に保持させるので、流量調整部材３がカバー４等の他の部材と干渉することを容易かつ確実に防止することができる。 In the present embodiment configured as described above, the structure for transmitting the operating force (rotational power) to the flow rate adjusting member 3 to the valve (valve body portion 14) is simple, which reduces the manufacturing cost. In addition, since the flow rate adjusting member 3 is held by the cover 4, it is possible to easily and reliably prevent the flow rate adjusting member 3 from interfering with other members such as the cover 4.

また、本実施の形態では、カバー４の表側に露出する継手部２と流量調整部材３とを一体化してあるため、カバー４の小型化を図れるという効果が得られる。 Moreover, in this Embodiment, since the coupling part 2 exposed to the front side of the cover 4 and the flow volume adjustment member 3 are integrated, the effect that size reduction of the cover 4 can be achieved is acquired.

さらに、本実施形態の継手部２は、図１に示すように、壁Ｗから前方に向けて水平となる角度よりも下方に傾斜するように延びるので、継手部２に対してその下方から接続することの多い継手部材Ｃの接続作業を行い易く、また、接続後の継手部材Ｃの壁Ｗからの突出量も小さく抑えることができ、省スペース化にも資する。 Further, as shown in FIG. 1, the joint portion 2 of the present embodiment extends from the wall W so as to incline downward from an angle that is horizontal toward the front, so that the joint portion 2 is connected to the joint portion 2 from below. It is easy to perform the connecting operation of the joint member C that is often performed, and the protruding amount of the joint member C after the connection from the wall W can be reduced, which contributes to space saving.

本形態では、施工現場により間柱Ｍと壁Ｗとの間隔や壁Ｗの厚みにばらつきがある場合でも、スペーサ２８の長さを変更することにより、流量調整部材３の壁Ｗの表側への迫り出し量（突出量）の一律化を図ることができ、これにより、設置後の埋め込み水栓の状態を容易に良好にすることができる上、スペーサ２８の長さを変更する（適宜の長さのスペーサ２８を選択する）のみでよいので施工性の向上をも図ることができる。加えて、本形態の埋め込み水栓では、流量調整部材３及びカバー４の両方が筒状部材９（水栓本体７）に固定（装着）されるので、壁Ｗの厚みに関係無くカバー４から流量調整部材３までの間隔が必然的に一定になり、これによっても埋め込み水栓の良好な設置を容易に行うことが可能となる。 In this embodiment, even when there is a variation in the distance between the stud M and the wall W or the thickness of the wall W depending on the construction site, the length of the spacer 28 is changed to approach the front side of the wall W of the flow rate adjusting member 3. The amount of protrusion (projection amount) can be made uniform, whereby the state of the embedded water faucet after installation can be easily improved and the length of the spacer 28 can be changed (appropriate length). Therefore, the workability can be improved. In addition, in the embedded faucet of this embodiment, both the flow rate adjusting member 3 and the cover 4 are fixed (attached) to the tubular member 9 (the faucet body 7), so that the cover 4 can be removed regardless of the thickness of the wall W. The interval to the flow rate adjusting member 3 is inevitably constant, and this also makes it possible to easily install the embedded faucet.

さらに、本形態の給水栓は、従来の埋め込み水栓で用いられるハウジングを不要とすることができるので、この点でもコストダウンに資するものとなり、設置スペースのコンパクト化の点でも優れている。 Further, the water faucet of the present embodiment can eliminate the housing used in the conventional embedded water faucet, which also contributes to cost reduction and is excellent in terms of downsizing the installation space.

なお、本発明は、上記の実施の形態に何ら限定されず、本発明の要旨を逸脱しない範囲において種々に変形して実施し得ることは勿論である。例えば、以下のような変形例を挙げることができる。 In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

給水対象Ｔは洗濯機に限られず、浄水器、食器洗い機、湯沸器などの他の機器であってもよい。 The water supply target T is not limited to a washing machine, and may be other devices such as a water purifier, a dishwasher, and a water heater.

流量調整部材３は、筒状部材９において水栓本体７内に挿入されない部分の外周側に、筒状部材９に対するトルク伝達及び筒状部材９の軸方向への移動が可能な状態で嵌合されればよい。そのような嵌合を可能とするには、例えば、セレーション、スプライン又はキーのうちから選択されるトルク伝達用の凹凸噛合構造を流量調整部材３と筒状部材９との嵌合部に設ければよく、上記実施の形態では、セレーションを選択した例を示したに過ぎない（上記実施の形態のセレーション嵌合部２０を参照）。 The flow rate adjusting member 3 is fitted on the outer peripheral side of a portion of the tubular member 9 that is not inserted into the faucet body 7 in a state that allows torque transmission to the tubular member 9 and movement of the tubular member 9 in the axial direction. It only has to be done. In order to enable such fitting, for example, an uneven meshing structure for torque transmission selected from serrations, splines or keys is provided in the fitting portion between the flow rate adjusting member 3 and the cylindrical member 9. What is necessary is just to show the example which selected the serration in the said embodiment (refer the serration fitting part 20 of the said embodiment).

上記実施形態では、流量調整部材３がカバー４に保持されているが、これに限らず、例えば、流量調整部材３が筒状部材９に保持されてもよい。また、流量調整部材３においてインナーセレーション２０ｂが設けられる部分は、筒状になっておらず、例えば縦断面視Ｃ字形状となっていてもよい。 In the above embodiment, the flow rate adjusting member 3 is held by the cover 4, but the present invention is not limited to this. For example, the flow rate adjusting member 3 may be held by the cylindrical member 9. Moreover, the part in which the inner serration 20b is provided in the flow rate adjusting member 3 is not cylindrical, and may be, for example, a C-shape in a longitudinal section.

上記実施形態の挿通孔７ｂを、接続具２６が螺合する雌ねじ部分としてもよい。 The insertion hole 7b of the above embodiment may be a female screw portion into which the connection tool 26 is screwed.

上記実施形態では、弁体部１４は筒状部材９の先端に別部材として装着されているが、このような別部材を用いず、筒状部材９の先端部を弁体部１４として用いることができるようにしてもよい。 In the said embodiment, although the valve body part 14 is mounted | worn as another member at the front-end | tip of the cylindrical member 9, the front-end | tip part of the cylindrical member 9 is used as the valve body part 14 without using such another member. You may be able to.

逆止弁１５が、例えば継手部２の下流側において発生する水撃（上記実施形態では給水対象Ｔである洗濯機の電磁弁の開閉操作の際に生じる水撃）を吸収、緩和するダンパー部を有するものであってもよい。 A damper portion that the check valve 15 absorbs and relaxes, for example, water hammer generated on the downstream side of the joint portion 2 (water hammer generated when the electromagnetic valve of the washing machine as the water supply target T is opened and closed in the above embodiment). It may have.

上記実施形態では、減圧板１６は弁体部１４とは別部材として設けられているが、これに限らず、例えば弁体部１４が減圧板１６の機能を兼ね備えるように構成し、弁体部１４と減圧板１６との一体化を図ってもよい。 In the above-described embodiment, the decompression plate 16 is provided as a separate member from the valve body portion 14, but is not limited thereto, and for example, the valve body portion 14 is configured to have the function of the decompression plate 16, and the valve body portion 14 and the decompression plate 16 may be integrated.

壁Ｗの厚みに関係無くカバー４ひいては給水栓１の良好な設置を容易に行うことを可能とするためには、壁Ｗの裏側に固定配置される保持具２１にカバー４を直接取り付けるのではなく、スペーサ２８によって位置調整される水栓本体７やこの水栓本体７に接続される部材（例えば筒状部材９や継手部２）への係止または固定によってカバー４を保持させるようにしてあればよい。従って、上記実施の形態では、カバー４を水栓本体７に対してねじ２９によって固定することにより、カバー４を保持するようにしてあるが、カバー４の保持方法はこれに限られない。 In order to enable easy installation of the cover 4 and thus the faucet 1 regardless of the thickness of the wall W, the cover 4 is not directly attached to the holder 21 fixedly arranged on the back side of the wall W. The cover 4 is held by being locked or fixed to the faucet body 7 whose position is adjusted by the spacer 28 or a member (for example, the cylindrical member 9 or the joint portion 2) connected to the faucet body 7. I just need it. Therefore, in the above embodiment, the cover 4 is held by fixing the cover 4 to the faucet body 7 with the screw 29, but the method of holding the cover 4 is not limited to this.

尚、例えば、図９に示す保持具２１を、図１０（Ａ）〜（Ｇ）に示すように第２取付け面部２３の無い形状となるように変形してもよい。 For example, the holder 21 shown in FIG. 9 may be deformed so as to have a shape without the second mounting surface portion 23 as shown in FIGS.

また、上記実施の形態では、壁Ｗの外側からみて取付孔Ｗａの左側にある間柱Ｍに保持具２１を取り付けているが、間柱Ｍが逆側（右側）にある場合にも保持具２１を取り付けることができるようにしてもよい。そのためには、例えば、水栓本体７において接続具２６が差し込まれる部分（挿通孔７ｂ）を水栓本体７の左側ではなく右側に（あるいは左右両側に）設ければよく、また、この場合、保持具２１は図４に示す向きでは用いることができないので、保持面部２４を前側に向けたまま保持具２１をそれぞれ上下逆にした状態で用いるようにすればよい。 In the above embodiment, the holder 21 is attached to the stud M on the left side of the mounting hole Wa when viewed from the outside of the wall W. However, the holder 21 is also attached when the stud M is on the opposite side (right side). It may be possible to attach it. For that purpose, for example, a portion (insertion hole 7b) into which the connector 26 is inserted in the faucet body 7 may be provided on the right side (or on both the left and right sides) instead of the left side of the faucet body 7, and in this case, Since the holder 21 cannot be used in the orientation shown in FIG. 4, the holder 21 may be used upside down with the holding surface portion 24 facing the front side.

尚、水栓本体７において接続具２６が差し込まれる部分（挿通孔７ｂ）は、水栓本体７の左右に限られず、例えば上側に設けることもできる。 In addition, the part (insertion hole 7b) in which the connection tool 26 is inserted in the faucet body 7 is not limited to the left and right sides of the faucet body 7, and may be provided on the upper side, for example.

ここで、図１１（Ａ）及び（Ｂ）に示すように、水栓本体７の左側のみではなく上側にも接続具２１が差し込まれる部分（雌ねじ部分７ｃ）を設ければ以下の効果が得られる。すなわち、図１０（Ａ）〜（Ｇ）に示すような第２取付け面部２３の無い保持具２１を用いる場合でも、保持面部２４を前側に向けた状態で第１取付け面部２２を上側に向けることにより、この図１０（Ａ）〜（Ｇ）に示す保持具２１を用いて水栓本体７を略水平に延びる当木の下面にも取り付けることが可能となる。また、図９（Ａ）〜（Ｇ）に示す保持具２１を用いる場合には、さらに、保持面部２４を前側に向けた状態で第２取付け面部２３を右側に向けることにより、この図９（Ａ）〜（Ｇ）に示す保持具２１を用いて水栓本体７を右側の間柱Ｍにも取り付けることが可能となる。 Here, as shown in FIGS. 11A and 11B, the following effects can be obtained by providing a portion (female screw portion 7c) into which the connector 21 is inserted not only on the left side of the faucet body 7, but also on the upper side. It is done. That is, even when the holder 21 without the second mounting surface portion 23 as shown in FIGS. 10A to 10G is used, the first mounting surface portion 22 is directed upward with the holding surface portion 24 facing the front side. Thus, it becomes possible to attach the faucet body 7 to the bottom surface of the tree extending substantially horizontally using the holder 21 shown in FIGS. 10 (A) to (G). Further, when the holder 21 shown in FIGS. 9A to 9G is used, the second mounting surface portion 23 is directed to the right side in a state where the holding surface portion 24 is directed to the front side. It becomes possible to attach the faucet body 7 to the right column M using the holder 21 shown in A) to (G).

また、図９（Ａ）〜（Ｇ）あるいは図１０（Ａ）〜（Ｇ）に示す保持具２１の鏡像となる形状（左右を逆にした形状）を有する保持具を用いることもでき、この場合には、接続具２６が差し込まれる部分（挿通孔７ｂ）を水栓本体７の左側ではなく右側に設ければよい。 Moreover, the holder which has the shape (shape which reversed right and left) used as the mirror image of the holder 21 shown to FIG. 9 (A)-(G) or FIG. 10 (A)-(G) can also be used. In that case, a portion (insertion hole 7b) into which the connection tool 26 is inserted may be provided on the right side instead of the left side of the faucet body 7.

接続具２６は座金組み込みねじに限られず、座金が組み込まれていないノーマルなタイプのねじの他、例えば、ボルトとナットであってもよい。 The connection tool 26 is not limited to a screw with a built-in washer, and may be, for example, a bolt and a nut in addition to a normal type screw without a washer.

スペーサ２８の長さを変更する方法としては、相互に長さの異なる複数のスペーサ２８から任意の長さを有するスペーサ２８を選択し着脱する上述の方法の他に、例えば、長めに成形したスペーサ２８を任意長さに切断する方法や、長さが同一あるいは相互に異なる複数のスペーサを適宜に組み合わせて用いる方法が挙げられる。 As a method of changing the length of the spacer 28, in addition to the above-described method of selecting and removing the spacer 28 having an arbitrary length from a plurality of spacers 28 having different lengths, for example, a spacer formed longer A method of cutting 28 to an arbitrary length and a method of using a plurality of spacers having the same length or different from each other in an appropriate combination are available.

挿通孔７ａ、スペーサ２８、保持面部２４を前側からこの順に並べる構成に限られず、例えば、挿通孔７ａ、スペーサ２８、保持面部２４を後側からこの順に並べてもよい。すなわち、上記実施の形態では、接続具２６を、水栓本体７において壁Ｗに対して保持面部２４よりも近くに位置する部分に差し込んであるが、水栓本体７において壁Ｗに対して保持面部２４よりも遠くに位置する部分に差し込むようにしてもよい。 The configuration is not limited to the configuration in which the insertion hole 7a, the spacer 28, and the holding surface portion 24 are arranged in this order from the front side. For example, the insertion hole 7a, the spacer 28, and the holding surface portion 24 may be arranged in this order from the rear side. That is, in the above-described embodiment, the connection tool 26 is inserted into a portion of the faucet body 7 that is located closer to the wall W than the holding surface portion 24, but is held by the faucet body 7 against the wall W. You may make it insert in the part located far from the surface part 24. FIG.

上記各変形を、適宜に組み合わせて行ってもよいことはいうまでもない。 Needless to say, the above modifications may be combined as appropriate.

なお、図２と対比すれば明らかなように、図５（Ａ）及び（Ｂ）、図７では調整部材３は図示されない位置にあるが、わかり易さのために図示してある。 As is clear from comparison with FIG. 2, the adjustment member 3 is not shown in FIGS. 5A, 5B, and 7, but is shown for the sake of clarity.
