Description

本開示は、水栓に関する。 This disclosure relates to a faucet.

従来の水栓には、例えば、特許文献１に記載されているものが知られている。特許文献１には、水栓本体と、回転する温調ハンドルと、温調ハンドルと同調して回転する係止部とを備える構造が記載されている。係止部が水栓本体に設けられた当たり面に当接すると、係止部の移動は規制され、水温調整部が高温側へ回転することを防止する。 A known conventional faucet is described in, for example, Patent Document 1. Patent Document 1 describes a structure that includes a faucet body, a rotating temperature control handle, and a locking part that rotates in unison with the temperature control handle. When the locking part comes into contact with a contact surface provided on the faucet body, movement of the locking part is restricted, preventing the water temperature adjustment part from rotating toward the higher temperature side.

特開２０１９－４４４６０号公報JP 2019-44460 A

しかしながら、従来の水栓においては、係止部と水栓本体との当接によって係止部または水栓本体が摩耗した場合、温度調節機能の維持が困難となり、温度調節に係る部材の耐摩耗性の向上が求められる。また、温度調節に係る部材が露出する場合、耐摩耗性に加えて、意匠性を考慮しながら、当該部材を設計することが求められている。このため、温度調節に係る部材の設計自由度を向上させるという観点において、未だ改善の余地があると言える。 However, in conventional faucets, if the locking part or the faucet body wears due to contact between the locking part and the faucet body, it becomes difficult to maintain the temperature regulating function, and there is a need to improve the wear resistance of the temperature regulating components. Furthermore, if the temperature regulating components are exposed, there is a need to design the components while taking into consideration design as well as wear resistance. For this reason, it can be said that there is still room for improvement in terms of increasing the design freedom of temperature regulating components.

したがって、本開示の目的は、上記課題を解決することにあって、温度調節に係る部材の設計自由度を向上できる水栓を提供することにある。 Therefore, the objective of this disclosure is to provide a faucet that can solve the above problems and improve the design freedom of components related to temperature regulation.

本開示の一態様の水栓は、湯及び水を混合する湯水混合弁と、湯水混合弁が軸方向に沿って内部に取り付けられる主管部と、主管部の端部に配置され、湯水混合弁に連結されるハンドルユニットと、主管部と前記ハンドルユニットとの間で主管部の端部に取り付けられ、ハンドルユニットの回転規制を行うストッパー部材と、ストッパー部材を覆うように主管部の端部に取り付けられ、ハンドルユニットに対して露出する露出部を有し、ストッパー部材とは異なるカラー部材と、を備える。 The faucet of one embodiment of the present disclosure comprises a hot and cold water mixing valve for mixing hot and cold water, a main pipe section to which the hot and cold water mixing valve is attached along the axial direction, a handle unit disposed at the end of the main pipe section and connected to the hot and cold water mixing valve, a stopper member attached to the end of the main pipe section between the main pipe section and the handle unit and restricting the rotation of the handle unit, and a collar member attached to the end of the main pipe section so as to cover the stopper member, having an exposed portion exposed to the handle unit, and different from the stopper member.

本開示に係る水栓によれば、温度調節に係る部材の設計自由度を向上できる。 The faucet disclosed herein allows for greater freedom in designing components related to temperature regulation.

図３Ａは、水栓１の部分拡大図である。図３Ｂは、水栓ユニット２の模式図である。図４Ａ及び図４Ｂは、水栓ユニット２の分解図である。図３Ｂ、図４Ａ、図４Ｂでは、温調ハンドル４Ａを図示しない。図４Ｂには、後述の水栓本体部５を省略した状態で水栓ユニット２が図示される。 Figure 3A is a partially enlarged view of the faucet 1. Figure 3B is a schematic diagram of the faucet unit 2. Figures 4A and 4B are exploded views of the faucet unit 2. The temperature control handle 4A is not shown in Figures 3B, 4A, and 4B. Figure 4B shows the faucet unit 2 without the faucet main body 5, which will be described later.

図３Ａ、図３Ｂ、図４Ａ及び図４Ｂに示すように、水栓ユニット２は、水栓本体部５（図４Ａ）と、前面カバー６と、背面カバー７（図４Ａ、図４Ｂ）と、エルボ８と、ストッパー部材９と、カラー部材１０と、カラー部材１１とを備える。 As shown in Figures 3A, 3B, 4A and 4B, the faucet unit 2 includes a faucet main body 5 (Figure 4A), a front cover 6, a rear cover 7 (Figures 4A and 4B), an elbow 8, a stopper member 9, a collar member 10 and a collar member 11.

図４Ａに示すように、水栓本体部５は、水栓ユニット２の本体を構成する部材である。水栓本体部５は、前述した湯供給管３８（図２）から供給される湯と水供給管３９（図２）から供給される水を混合する機能を有する。 As shown in FIG. 4A, the faucet main body 5 is a component that constitutes the main body of the faucet unit 2. The faucet main body 5 has the function of mixing the hot water supplied from the hot water supply pipe 38 (FIG. 2) and the water supplied from the cold water supply pipe 39 (FIG. 2) described above.

水栓本体部５は、軸方向Ｋに並ぶ湯水混合弁２０（図４Ｂ）と、切替弁２１（図４Ｂ）とを収容する。水栓本体部５には、一方側の端部から湯水混合弁２０が第１軸方向Ｋ１に挿入して取り付けられ、他方側の端部から切替弁２１が第２軸方向Ｋ２に挿入して取り付けられる。第１軸方向Ｋ１は、湯水混合弁２０から切替弁２１に向かう方向であり、第２軸方向Ｋ２は、切替弁２１から湯水混合弁２０に向かう方向である。 The faucet main body 5 houses a hot and cold water mixing valve 20 (Fig. 4B) and a switching valve 21 (Fig. 4B) lined up in the axial direction K. The hot and cold water mixing valve 20 is attached to the faucet main body 5 by inserting it into one end in the first axial direction K1, and the switching valve 21 is attached to the other end by inserting it into the second axial direction K2. The first axial direction K1 is the direction from the hot and cold water mixing valve 20 toward the switching valve 21, and the second axial direction K2 is the direction from the switching valve 21 toward the hot and cold water mixing valve 20.

湯水混合弁２０は、湯と水の混合割合を調整するための弁である。湯水混合弁２０は、サーモカートリッジとも呼ばれる。切替弁２１は、湯水混合弁２０で混合された湯水の吐水量及び吐水方向を変更するための部材である。本実施形態の切替弁２１は、湯水の吐水方向をシャワー吐水とカラン吐水との間で変更する。湯水混合弁２０の端部には温調ハンドル４Ａ（図１、図２）と係り合うギア部４０Ａが取り付けられる。切替弁２１の端部には切替ハンドル４Ｂ（図１、図２）と係り合うギア部４０Ｂが取り付けられる。 The hot and cold water mixing valve 20 is a valve for adjusting the mixing ratio of hot and cold water. The hot and cold water mixing valve 20 is also called a thermo cartridge. The changeover valve 21 is a member for changing the amount and direction of hot and cold water discharged from the hot and cold water mixing valve 20. The changeover valve 21 of this embodiment changes the direction of hot and cold water discharge between shower discharge and faucet discharge. A gear portion 40A that engages with the temperature control handle 4A (Figures 1 and 2) is attached to the end of the hot and cold water mixing valve 20. A gear portion 40B that engages with the changeover handle 4B (Figures 1 and 2) is attached to the end of the changeover valve 21.

上述より、水栓１は、湯水混合弁２０及び切替弁２１を備えるサーモスタット式水栓である。 As described above, the faucet 1 is a thermostatic faucet equipped with a hot and cold water mixing valve 20 and a switching valve 21.

水栓本体部５は、主管部１２と、湯供給用枝管部１３と、水供給用枝管部１４と、シャワー吐水用枝管部１５と、カラン吐水用枝管部１６とを備える。 The faucet body 5 includes a main pipe 12, a hot water supply branch pipe 13, a cold water supply branch pipe 14, a shower discharge branch pipe 15, and a faucet discharge branch pipe 16.

主管部１２は、前述した湯水混合弁２０及び切替弁２１を内部に収容する部材であり、筒状に形成される。湯供給用枝管部１３及び水供給用枝管部１４は、主管部１２から分岐して浴室の壁に向かって（Ｘ方向に）延びる管状部材である。湯供給用枝管部１３は、図示しない湯供給源に接続され、主管部１２に湯を供給する。水供給用枝管部１４は、図示しない水供給源に接続され、主管部１２に水を供給する。シャワー吐水用枝管部１５は、主管部１２から浴室の壁に向かって（Ｘ方向）延びる管状部材であり、エルボ８が接続され、エルボ８および図示しないシャワーホースを介して湯水を図示しないシャワーヘッドから流出させる。カラン吐水用枝管部１６は、主管部１２から浴室の床（－Ｚ方向）に向かって延びる管状の部材であり、図示しないカラン吐水部が接続され、カラン吐水部を介して湯水を図示しないカランから流出させる。 The main pipe section 12 is a member that houses the hot and cold water mixing valve 20 and the switching valve 21 described above, and is formed in a cylindrical shape. The hot water supply branch pipe section 13 and the water supply branch pipe section 14 are tubular members that branch off from the main pipe section 12 and extend (in the X direction) toward the wall of the bathroom. The hot water supply branch pipe section 13 is connected to a hot water supply source (not shown) and supplies hot water to the main pipe section 12. The water supply branch pipe section 14 is connected to a water supply source (not shown) and supplies water to the main pipe section 12. The shower discharge branch pipe section 15 is a tubular member that extends from the main pipe section 12 toward the wall of the bathroom (in the X direction), and is connected to an elbow 8, and hot and cold water flows out of a shower head (not shown) via the elbow 8 and a shower hose (not shown). The faucet discharge branch pipe section 16 is a tubular member that extends from the main pipe section 12 toward the bathroom floor (-Z direction) and is connected to a faucet discharge section (not shown), which causes hot and cold water to flow out of a faucet (not shown).

また、水栓本体部５は、前面カバー６及び背面カバー７に覆われる。 The faucet main body 5 is covered by a front cover 6 and a rear cover 7.

前面カバー６及び背面カバー７は、水栓本体部５を覆うように互いに嵌合し、水栓１の外観を形成する部材である。背面カバー７は、複数の開口７１、７２、７３を形成する。具体的には、エルボ８を接続するための開口７１と、湯供給管３８を接続するための開口７２と、水供給管３９を接続するための開口７３とが形成される。 The front cover 6 and the back cover 7 are members that fit together to cover the faucet main body 5 and form the external appearance of the faucet 1. The back cover 7 has multiple openings 71, 72, and 73. Specifically, an opening 71 for connecting the elbow 8, an opening 72 for connecting the hot water supply pipe 38, and an opening 73 for connecting the cold water supply pipe 39 are formed.

エルボ８は、水栓本体部５のシャワー吐水用枝管部１５を、図示しないシャワーホースに接続する管状の連結部材である。 The elbow 8 is a tubular connecting member that connects the shower discharge branch pipe 15 of the faucet main body 5 to a shower hose (not shown).

水栓本体部５の主管部１２の第２軸方向Ｋ２側の端部には、温調ハンドル４Ａ（図２）、カラー部材１０、及びストッパー部材９が取り付けられる。水栓本体部５の主管部１２の第１軸方向Ｋ１側の端部には、切替ハンドル４Ｂ（図２）及びカラー部材１１が取り付けられる。ストッパー部材９、カラー部材１０、及びカラー部材１１はそれぞれ筒状部材であり、軸方向Ｋに沿って延びる。 A temperature control handle 4A (Fig. 2), a collar member 10, and a stopper member 9 are attached to the end of the main pipe 12 of the faucet body 5 on the second axial direction K2 side. A switching handle 4B (Fig. 2) and a collar member 11 are attached to the end of the main pipe 12 of the faucet body 5 on the first axial direction K1 side. The stopper member 9, collar member 10, and collar member 11 are each cylindrical members that extend along the axial direction K.

ストッパー部材９は、水栓１から吐水される湯水の上限温度を規定する部材であり、温調ハンドル４Ａ（図２）の回転を規制する。温調ハンドル４Ａが回転しストッパー部材９に当接されると、ストッパー部材９は、温調ハンドル４Ａのさらなる回転を規制する。 The stopper member 9 is a member that determines the upper limit temperature of hot and cold water discharged from the faucet 1, and restricts the rotation of the temperature control handle 4A (Figure 2). When the temperature control handle 4A rotates and abuts against the stopper member 9, the stopper member 9 restricts further rotation of the temperature control handle 4A.

カラー部材１０、１１はそれぞれ、前面カバー６及び背面カバー７によって挟まれ、前面カバー６及び背面カバー７の各端部を支持する部材である。カラー部材１０及びカラー部材１１は、水栓本体部５に対する前面カバー６及び背面カバー７の取付位置を規定する。特にカラー部材１０は、ストッパー部材９の外側に配置され、ストッパー部材９を覆う機能を有する。図３Ａに示すように、カラー部材１０は、その一部が温調ハンドル４Ａに対して露出する露出部３０を有する。露出部３０は、後述のフランジ部３５の一部である。本実施形態では、外側に露出しないストッパー部材９の材料と、外側に露出するカラー部材１０の材料とを異ならせることで、ストッパー部材９の寿命向上と、カラー部材１０の意匠性向上とを両立させている。 The collar members 10 and 11 are sandwiched between the front cover 6 and the rear cover 7, and support the ends of the front cover 6 and the rear cover 7. The collar members 10 and 11 determine the mounting positions of the front cover 6 and the rear cover 7 relative to the faucet main body 5. In particular, the collar member 10 is disposed outside the stopper member 9 and has the function of covering the stopper member 9. As shown in FIG. 3A, the collar member 10 has an exposed portion 30, a part of which is exposed to the temperature control handle 4A. The exposed portion 30 is a part of the flange portion 35 described below. In this embodiment, the material of the stopper member 9 that is not exposed to the outside is different from the material of the collar member 10 that is exposed to the outside, thereby improving the lifespan of the stopper member 9 and improving the design of the collar member 10 at the same time.

図４Ｃは、水栓ユニット２の部分分解図である。ストッパー部材９及びカラー部材１０は、カラー部材１０がストッパー部材９を覆うように、主管部１２の第２軸方向Ｋ２側に取り付けられる。ストッパー部材９及びカラー部材１０は、ともに主管部１２の端部のギア部４０Ａを通過させる筒状の形状を有する。また、後述するように、ストッパー部材９とカラー部材１０とは、それぞれ主管部１２の端部に取り付けられるだけではなく、互いに嵌合する。 Figure 4C is a partial exploded view of the faucet unit 2. The stopper member 9 and collar member 10 are attached to the second axial direction K2 side of the main pipe 12 so that the collar member 10 covers the stopper member 9. Both the stopper member 9 and collar member 10 have a cylindrical shape that allows the gear portion 40A at the end of the main pipe 12 to pass through. As described below, the stopper member 9 and collar member 10 are not only attached to the end of the main pipe 12, but also fit into each other.

図５～図８を参照しながら、ストッパー部材９と、カラー部材１０とについて、より詳細に説明する。図５及び図６は、ストッパー部材９の斜視図である。図７及び図８は、カラー部材１０の斜視図である。 The stopper member 9 and collar member 10 will be described in more detail with reference to Figures 5 to 8. Figures 5 and 6 are perspective views of the stopper member 9. Figures 7 and 8 are perspective views of the collar member 10.

図５及び図６に示すように、ストッパー部材９は、第１軸方向Ｋ１に沿って順に配置される筒部３１と筒部３２とを有する。筒部３２が筒部３１より大きい径方向寸法を有するため、ストッパー部材９は、筒部３１から筒部３２に向かって拡大する段付きの筒状形状を有する。本実施形態のストッパー部材９は、筒部３１および筒部３２を含めて一体的に形成される。 As shown in Figures 5 and 6, the stopper member 9 has a cylindrical portion 31 and a cylindrical portion 32 that are arranged in sequence along the first axial direction K1. Since the cylindrical portion 32 has a radial dimension larger than that of the cylindrical portion 31, the stopper member 9 has a stepped cylindrical shape that expands from the cylindrical portion 31 toward the cylindrical portion 32. The stopper member 9 of this embodiment is integrally formed including the cylindrical portion 31 and the cylindrical portion 32.

筒部３１の一方の端部には、温調ハンドル４Ａの回転を規制する突起３１Ａが形成される。突起３１Ａは、筒部３１の端部から第２軸方向Ｋ２に突出して、筒部３１の外周の一部に沿って形成される。突起３１Ａは、突起３１Ａの端面Ｒ１から、周方向Ｍに延びる。周方向Ｍにおいて、第１軸方向Ｋ１から見て反時計回りを第１周方向Ｍ１とする。突起３１Ａの端面Ｒ１は、温調ハンドル４Ａ（図２）に当接し、後述の温調ハンドル４Ａの第１回転規制位置Ｐ１を規定する。第１周方向Ｍ１側の突起３１Ａに隣接して、突起３１Ｂが形成される。突起３１Ｂは、突起３１Ａに対して径方向内側に突出する。突起３１Ａと突起３１Ｂとの間の端面Ｒ２は、温調ハンドル４Ａに当接し、後述の温調ハンドル４Ａの第２回転規制位置Ｐ２を規定する。突起３１Ｂの径方向外側部分には、凹部３１Ｃ（図５）が形成される。このような構造によって、突起３１Ｂの強度を確保しつつ、ストッパー部材９の成形性を向上させることができる。 At one end of the cylindrical portion 31, a protrusion 31A that restricts the rotation of the temperature control handle 4A is formed. The protrusion 31A protrudes from the end of the cylindrical portion 31 in the second axial direction K2 and is formed along a part of the outer circumference of the cylindrical portion 31. The protrusion 31A extends in the circumferential direction M from the end face R1 of the protrusion 31A. In the circumferential direction M, the counterclockwise direction as viewed from the first axial direction K1 is the first circumferential direction M1. The end face R1 of the protrusion 31A abuts against the temperature control handle 4A (FIG. 2) and defines the first rotation restriction position P1 of the temperature control handle 4A described later. A protrusion 31B is formed adjacent to the protrusion 31A on the first circumferential direction M1 side. The protrusion 31B protrudes radially inward relative to the protrusion 31A. The end face R2 between the protrusion 31A and the protrusion 31B abuts against the temperature control handle 4A and defines the second rotation restriction position P2 of the temperature control handle 4A described later. A recess 31C (Figure 5) is formed on the radially outer portion of the protrusion 31B. This structure improves the moldability of the stopper member 9 while ensuring the strength of the protrusion 31B.

筒部３１の他方の端部は、接続部３３を介して、筒部３２の端部に接続される。接続部３３は、筒部３１の他方の端部から筒部３２の端部まで径方向に延びる環状の部分である。 The other end of the tubular portion 31 is connected to the end of the tubular portion 32 via the connection portion 33. The connection portion 33 is an annular portion that extends radially from the other end of the tubular portion 31 to the end of the tubular portion 32.

接続部３３は、径方向において対向する位置に２つの孔部３３Ａを形成する。孔部３３Ａには、後述のカラー部材１０の爪部３４Ａ（図７、図８）が挿入される。これにより、ストッパー部材９とカラー部材１０が爪嵌合する。孔部３３Ａの両側に沿って、第２軸方向Ｋ２に突出するガイド部３３Ｂが設けられる。ガイド部３３Ｂによって、孔部３３Ａに対する爪部３４Ａのガタツキを抑制することができる。 The connection portion 33 has two holes 33A formed at radially opposing positions. The claw portions 34A (FIGS. 7 and 8) of the collar member 10 described below are inserted into the holes 33A. This allows the stopper member 9 and the collar member 10 to be claw-fitted. Guide portions 33B protruding in the second axial direction K2 are provided along both sides of the holes 33A. The guide portions 33B can suppress rattling of the claw portions 34A relative to the holes 33A.

接続部３３には、孔部３３Ａと異なる位置に、径方向において対向する位置に２つの孔部３３Ｃ（図６、図５）をさらに形成する。孔部３３Ｃには、後述の爪部３４Ｂが挿入される。これにより、ストッパー部材９とカラー部材１０が爪嵌合する。孔部３３Ｃの両側に沿って、筒部３１の外周から径方向外側に突出するガイド部３３Ｄが設けられる。ガイド部３３Ｄによって、孔部３３Ｃに対する爪部３４Ｂのガタツキを抑制することができる。ガタツキを抑制しつつ、ストッパー部材９とカラー部材１０との嵌合を阻害しないことを考慮することで、ガイド部３３Ｂ、３３Ｄの突出量が決まる。 The connecting portion 33 further has two holes 33C (Figs. 6 and 5) formed at positions different from the hole 33A and facing each other in the radial direction. The claws 34B described below are inserted into the holes 33C. This allows the stopper member 9 and the collar member 10 to engage with each other. Along both sides of the hole 33C, guide portions 33D are provided that protrude radially outward from the outer periphery of the tube portion 31. The guide portions 33D can suppress rattling of the claws 34B relative to the hole 33C. The protruding amounts of the guide portions 33B and 33D are determined by considering how to suppress rattling while not impeding the engagement between the stopper member 9 and the collar member 10.

筒部３２の周壁は、対向する位置において、２つの切欠き部３２Ａを形成する。切欠き部３２Ａは、後述の爪部３５Ａを通過させるための切欠きであり、軸方向Ｋに沿って筒部３２の周壁の一部を切り取ることによって形成される。切欠き部３２Ａを通過する爪部３５Ａは、主管部１２の端部に到達する。筒部３２は、切欠き部３２Ａの両側に位置して径方向に向かって突出する凸部３２Cを有する。このような構成によって、切欠き部３２Ａに対する爪部３５Ａの脱離を抑制することができる。 The peripheral wall of the tubular portion 32 forms two notches 32A at opposing positions. The notches 32A are notches for passing the claw portions 35A described below, and are formed by cutting out a portion of the peripheral wall of the tubular portion 32 along the axial direction K. The claw portions 35A that pass through the notches 32A reach the end of the main pipe portion 12. The tubular portion 32 has convex portions 32C that are located on both sides of the notches 32A and protrude in the radial direction. This configuration makes it possible to prevent the claw portions 35A from coming off the notches 32A.

筒部３２の第１軸方向Ｋ１側の端部には、２つの凸部３２Ｂ（図６）が形成される。２つの凸部３２Ｂは、ストッパー部材９を主管部１２の外周面に対して位置決めするための凸部であり、筒部３２の端部から第２軸方向Ｋ２に突出する。凸部３２Ｂは、主管部１２の外周面に形成される凹部５０（図４Ａ）に挿入されることで、主管部１２に対するカラー部材１０の周方向Ｍの位置合わせが実現される。 Two protrusions 32B (Fig. 6) are formed on the end of the tubular portion 32 on the first axial direction K1 side. The two protrusions 32B are protrusions for positioning the stopper member 9 with respect to the outer peripheral surface of the main pipe portion 12, and protrude from the end of the tubular portion 32 in the second axial direction K2. The protrusions 32B are inserted into recesses 50 (Fig. 4A) formed on the outer peripheral surface of the main pipe portion 12, thereby realizing the alignment of the collar member 10 in the circumferential direction M with respect to the main pipe portion 12.

上述した構成を有するストッパー部材９は、カラー部材１０より高い曲げ弾性率を有する材料で形成される。ストッパー部材９は、例えば、ＰＰＳで形成される。ストッパー部材９は、エンジニアリングプラスチックと称されるプラスチック材料で形成されてもよい。ストッパー部材９は、カラー部材１０より高い引張強度を有する材料で形成されてもよい。また、ストッパー部材９は、カラー部材１０より小さい摩擦係数を有する材料で形成されてもよい。 The stopper member 9 having the above-mentioned configuration is formed of a material having a higher flexural modulus than the collar member 10. The stopper member 9 is formed of, for example, PPS. The stopper member 9 may be formed of a plastic material called engineering plastic. The stopper member 9 may be formed of a material having a higher tensile strength than the collar member 10. The stopper member 9 may also be formed of a material having a smaller coefficient of friction than the collar member 10.

図７及び図８に示すように、カラー部材１０は、筒部３４と、フランジ部３５とを有する。筒部３４は、ストッパー部材９の筒部３１の外側を囲むように配置される円筒状の部材である。フランジ部３５は、前面カバー６及び背面カバー７に挟まれ、前面カバー６及び背面カバー７を支持する部材であり、筒部３４の第２軸方向Ｋ２側の端部から軸方向Ｋに対して略垂直に延びる板状の形状を有する。 As shown in Figures 7 and 8, the collar member 10 has a tube portion 34 and a flange portion 35. The tube portion 34 is a cylindrical member arranged to surround the outside of the tube portion 31 of the stopper member 9. The flange portion 35 is a member that is sandwiched between the front cover 6 and the rear cover 7 and supports the front cover 6 and the rear cover 7, and has a plate-like shape that extends approximately perpendicular to the axial direction K from the end of the tube portion 34 on the second axial direction K2 side.

筒部３４におけるフランジ部３５に接続される端部には、対向する位置において、当該端部から第１軸方向Ｋ１に突出する２つの爪部３４Ａ（図８）が形成される。爪部３４Ａは、孔部３３Ａ（図５、図６）に挿入され、カラー部材１０とストッパー部材９とが嵌合される。爪部３４Ａは、筒部３４の内側に配置される。このような構成によって、カラー部材１０の省スペース化を実現することができる。また、爪部３４Ａにおいて、筒部３４の外周面までの変形幅を確保することができる。 At the end of the tube portion 34 connected to the flange portion 35, two claw portions 34A (Fig. 8) are formed at opposing positions and protrude from the end in the first axial direction K1. The claw portions 34A are inserted into the hole portions 33A (Figs. 5 and 6), and the collar member 10 and the stopper member 9 are fitted together. The claw portions 34A are disposed inside the tube portion 34. This configuration makes it possible to reduce the space required for the collar member 10. In addition, the deformation width of the claw portions 34A up to the outer circumferential surface of the tube portion 34 can be ensured.

筒部３４におけるフランジ部３５に接続される端部には、対向する位置において、第１軸方向Ｋ１に突出する２つの爪部３４Ｂがさらに形成される。爪部３４Ｂは孔部３３Ｃ（図５、図６）に挿入され、カラー部材１０とストッパー部材９とが嵌合される。 Two claws 34B are further formed at opposing positions on the end of the tube portion 34 that is connected to the flange portion 35 and protrude in the first axial direction K1. The claws 34B are inserted into the hole portion 33C (Figures 5 and 6), and the collar member 10 and the stopper member 9 are fitted together.

爪部３４Ａと爪部３４Ｂとは、周方向Ｍに沿って異なる幅寸法を有し、爪部３４Ａは爪部３４Ｂより大きい幅を有する。そのため、爪部３４Ａを孔部３３Ｃに挿入することはできず、カラー部材１０を誤った方向で取り付けることを防止できる。また、爪部３４Ａは爪部３４Ｂより小さい厚みを有する。爪部３４Ａが薄いため、爪部３４Ａはたわむことができ、容易に孔部３３Ｃに挿入し、ストッパー部材９とカラー部材１０との嵌合を容易に実現できる。一方で、爪部３４Ｂが厚いため、ストッパー部材９とカラー部材１０と相対的な回転を規制することができる。 The claw portion 34A and the claw portion 34B have different width dimensions along the circumferential direction M, and the claw portion 34A has a width greater than the claw portion 34B. Therefore, the claw portion 34A cannot be inserted into the hole portion 33C, and it is possible to prevent the collar member 10 from being attached in the wrong direction. In addition, the claw portion 34A has a thickness smaller than that of the claw portion 34B. Because the claw portion 34A is thin, the claw portion 34A can bend and can be easily inserted into the hole portion 33C, and it is possible to easily realize the engagement between the stopper member 9 and the collar member 10. On the other hand, because the claw portion 34B is thick, it is possible to restrict the relative rotation between the stopper member 9 and the collar member 10.

フランジ部３５にも同様に、複数の爪部３６、３５Ａ、３５Ｂ、及び凸部３５Ｃが設けられている。 Similarly, the flange portion 35 is provided with multiple claw portions 36, 35A, 35B, and a protrusion 35C.

フランジ部３５の一方側に形成される爪部３６は、ストッパー部材９の切欠き部３２Ａ（図５、図６）を通過して主管部１２（図４Ａ）の外周面に嵌合するための爪部である。爪部３６は、フランジ部３５から第２軸方向Ｋ２に突出した形状を有する。爪部３６は、孔部３６Ａを形成する。孔部３６Ａは、主管部１２の外周面に形成された凸部５１（図４Ａ）を配置するための貫通孔であり、カラー部材１０を主管部１２の外周面に対して爪嵌合させる。よって、主管部１２に対するカラー部材１０の位置合わせ及び固定が実現される。さらに、爪部３６が切欠き部３２Ａを通ることによって、カラー部材１０と主管部１２と間に、ストッパー部材９が把持される。 The claw portion 36 formed on one side of the flange portion 35 is a claw portion for passing through the notch portion 32A (Figs. 5 and 6) of the stopper member 9 and fitting into the outer peripheral surface of the main pipe portion 12 (Fig. 4A). The claw portion 36 has a shape that protrudes from the flange portion 35 in the second axial direction K2. The claw portion 36 forms a hole portion 36A. The hole portion 36A is a through hole for arranging the protrusion portion 51 (Fig. 4A) formed on the outer peripheral surface of the main pipe portion 12, and the collar member 10 is claw-fitted into the outer peripheral surface of the main pipe portion 12. Thus, the collar member 10 is aligned and fixed to the main pipe portion 12. Furthermore, the stopper member 9 is gripped between the collar member 10 and the main pipe portion 12 by the claw portion 36 passing through the notch portion 32A.

爪部３６と対向するフランジ部３５の他方側の位置に、爪部３５Ａは形成される。爪部３５Ａの両側には爪部３５Ｂが形成される。爪部３５Ａ、３５Ｂはともに、カラー部材１０を背面カバー７に篏合させるための爪部である。爪部３５Ａは、第１軸方向Ｋ１に突出し、９の切欠き部３２Ａ（図５、図６）を通過して背面カバー７の内側面に形成される凹部７０Ａ（図４Ａ、図４Ｂ）に嵌合する。爪部３５Ｂは、第１軸方向Ｋ１に突出し、切欠き部３２Ａの上下を通過して背面カバー７の内側面に形成される凹部７０Ｂ（図４Ａ、図４Ｂ）に嵌合する。よって、フランジ部３５に対する背面カバー７の位置が決まる。 Claw portion 35A is formed at the other side of flange portion 35 opposite claw portion 36. Claw portions 35B are formed on both sides of claw portion 35A. Both claw portions 35A and 35B are claw portions for fitting collar member 10 to rear cover 7. Claw portion 35A protrudes in first axial direction K1, passes through notch portion 32A (FIGS. 5 and 6) of 9, and fits into recess 70A (FIGS. 4A and 4B) formed on the inner side of rear cover 7. Claw portion 35B protrudes in first axial direction K1, passes through notch portion 32A above and below, and fits into recess 70B (FIGS. 4A and 4B) formed on the inner side of rear cover 7. Thus, the position of rear cover 7 relative to flange portion 35 is determined.

フランジ部３５の上部に形成される凸部３５Ｃは、カラー部材１０を前面カバー６に篏合させるための凸部である。凸部３５Ｃは、第１軸方向Ｋ１に突出し、前面カバー６の内側面に形成される凸部６０（図４Ａ、図４Ｂ）に当接される。よって、フランジ部３５に対する前面カバー６の位置が決まる。このように構成によって、フランジ部３５は、前面カバー６と背面カバー７との位置合わせ及び固定を実現できる。 The protrusion 35C formed on the upper part of the flange portion 35 is a protrusion for fitting the collar member 10 to the front cover 6. The protrusion 35C protrudes in the first axial direction K1 and abuts against a protrusion 60 (Figs. 4A and 4B) formed on the inner surface of the front cover 6. This determines the position of the front cover 6 relative to the flange portion 35. With this configuration, the flange portion 35 can align and fix the front cover 6 and the rear cover 7.

また、爪部３５Ａ、３６とは、異なる幅を有する。そのため、カラー部材１０を誤った方向で取り付けることを防止できる。 The claws 35A and 36 also have different widths. This prevents the collar member 10 from being attached in the wrong direction.

上述した構成を有するカラー部材１０は、筒部３４およびフランジ部３５を含めて一体的に形成される。カラー部材１０は、ストッパー部材９よりも曲げ弾性率が小さい材料で形成される、すなわち加工後の表面特性が良い材料で形成される。本明細書にて、「表面特性」とは、人の視覚で認識できる成形後の表面の状態を意味する。「表面特性が良い」は、例えば、フローマークの形成が抑制されている状態、表面粗さが小さい状態、設計された色を有している状態等を意味する。カラー部材１０は、例えば、ＡＢＳ、ＰＭＭＡ、ＡＳＡで形成される。 The collar member 10 having the above-mentioned configuration is integrally formed including the tube portion 34 and the flange portion 35. The collar member 10 is formed from a material having a smaller flexural modulus than the stopper member 9, i.e., a material having good surface properties after processing. In this specification, "surface properties" refers to the state of the surface after molding that can be recognized by the human eye. "Good surface properties" refers to, for example, a state in which the formation of flow marks is suppressed, a state in which the surface roughness is small, a state in which the designed color is possessed, and the like. The collar member 10 is formed from, for example, ABS, PMMA, or ASA.

ここで、図９Ａ～図９Ｃを参照しながら、嵌合された状態におけるストッパー部材９、カラー部材１０、主管部１２及び背面カバー７について説明する。 Now, with reference to Figures 9A to 9C, we will explain the stopper member 9, collar member 10, main pipe portion 12, and rear cover 7 in the engaged state.

図９Ａ～図９Ｃは、ストッパー部材９とカラー部材１０との嵌合を示す図である。図９Ａ～図９Ｃに示すように、ストッパー部材９及びカラー部材１０は、主管部１２の第２軸方向Ｋ２側の端部に取り付けられる。さらに、カラー部材１０のフランジ部３５には、前面カバー６（図示せず）と背面カバー７とが取り付けられ、併せて主管部１２を収容する筐体部材を形成する。ストッパー部材９は、カラー部材１０、前面カバー６及び背面カバー７に覆われ、外部への露出が抑制される。 Figures 9A to 9C are diagrams showing the engagement between the stopper member 9 and the collar member 10. As shown in Figures 9A to 9C, the stopper member 9 and collar member 10 are attached to the end of the main pipe portion 12 on the second axial direction K2 side. In addition, a front cover 6 (not shown) and a rear cover 7 are attached to the flange portion 35 of the collar member 10, which together form a housing member that houses the main pipe portion 12. The stopper member 9 is covered by the collar member 10, the front cover 6, and the rear cover 7, preventing it from being exposed to the outside.

カラー部材１０の筒部３４は、フランジ部３５から第２軸方向Ｋ２側に突出する。ストッパー部材９の筒部３１は、筒部３４の内側に配置された状態で、フランジ部３５から第２軸方向Ｋ２側に突出する。また、フランジ部３５に対する筒部３１の突出量は、筒部３４の突出量より小さい。よって、筒部３１の外周面は、筒部３４の内周面に対向し、筒部３１はカラー部材１０に覆われる。一方で、ストッパー部材９の筒部３２は、フランジ部３５から第１軸方向Ｋ１側に突出する。筒部３２は、カラー部材１０に覆われないが、前面カバー６と背面カバー７とに覆われる。このような構造において、ストッパー部材９の筒部３１はカラー部材１０の筒部３４に、筒部３２は前面カバー６及び背面カバー７に覆われ、ストッパー部材９の外部への露出が抑制される。 The tubular portion 34 of the collar member 10 protrudes from the flange portion 35 toward the second axial direction K2. The tubular portion 31 of the stopper member 9 protrudes from the flange portion 35 toward the second axial direction K2 while being disposed inside the tubular portion 34. The amount of protrusion of the tubular portion 31 relative to the flange portion 35 is smaller than the amount of protrusion of the tubular portion 34. Therefore, the outer peripheral surface of the tubular portion 31 faces the inner peripheral surface of the tubular portion 34, and the tubular portion 31 is covered by the collar member 10. On the other hand, the tubular portion 32 of the stopper member 9 protrudes from the flange portion 35 toward the first axial direction K1. The tubular portion 32 is not covered by the collar member 10, but is covered by the front cover 6 and the rear cover 7. In this structure, the tubular portion 31 of the stopper member 9 is covered by the tubular portion 34 of the collar member 10, and the tubular portion 32 is covered by the front cover 6 and the rear cover 7, suppressing exposure of the stopper member 9 to the outside.

また、ストッパー部材９及びカラー部材１０が主管部１２の端部に取り付けられると、主管部１２のギア部４０Ａは、ストッパー部材９及びカラー部材１０から突出する。 When the stopper member 9 and collar member 10 are attached to the end of the main pipe portion 12, the gear portion 40A of the main pipe portion 12 protrudes from the stopper member 9 and collar member 10.

ストッパー部材９及びカラー部材１０が取り付けられた主管部１２の端部には、温調ハンドル４Ａがさらに取り付けられる。温調ハンドル４Ａは、ギア部４０Ａと篏合して、ギア部４０Ａに接続された湯水混合弁２０を回転させる機能を有する。 A temperature control handle 4A is further attached to the end of the main pipe 12 to which the stopper member 9 and collar member 10 are attached. The temperature control handle 4A is engaged with the gear portion 40A and has the function of rotating the hot and cold water mixing valve 20 connected to the gear portion 40A.

温調ハンドル４Ａの第１軸方向Ｋ１側の端部と、フランジ部３５とは対向する。温調ハンドル４Ａをギア部４０Ａに取り付けた状態において、温調ハンドル４Ａとフランジ部３５との間に微小な隙間が形成され、温調ハンドル４Ａはフランジ部３５に対して相対的に回転する。 The end of the temperature control handle 4A on the first axial direction K1 side faces the flange portion 35. When the temperature control handle 4A is attached to the gear portion 40A, a small gap is formed between the temperature control handle 4A and the flange portion 35, and the temperature control handle 4A rotates relative to the flange portion 35.

図１０は温調ハンドル４Ａの斜視図であり、図１１は当接部材の斜視図である。 Figure 10 is an oblique view of the temperature control handle 4A, and Figure 11 is an oblique view of the contact member.

図１０に示すように、温調ハンドル４Ａは、グリップ部材４１と当接部材４２とを備える。グリップ部材４１は、水栓１の使用者が操作する回転可能な部材であり、温調ハンドル４Ａの外周部を構成する。グリップ部材４１は、水栓１の端部において、水栓１の外観の一部を形成する。グリップ部材４１の内壁には、ギア溝４１Ａが形成される。ギア溝４１Ａは、水栓本体部５のギア部４０Ａと嵌合し、グリップ部材４１の回転によって、ギア部４０Ａを回転させる。 As shown in FIG. 10, the temperature control handle 4A comprises a grip member 41 and an abutment member 42. The grip member 41 is a rotatable member operated by the user of the faucet 1, and constitutes the outer periphery of the temperature control handle 4A. The grip member 41 forms part of the exterior of the faucet 1 at the end of the faucet 1. A gear groove 41A is formed on the inner wall of the grip member 41. The gear groove 41A fits into the gear portion 40A of the faucet main body 5, and rotation of the grip member 41 rotates the gear portion 40A.

当接部材４２は、グリップ部材４１の内側に配置され、グリップ部材４１の回転を規制する部材である。当接部材４２がグリップ部材４１の回転を規制することで、水栓１から吐水される湯水の上限温度を設定することができる。図１１に示すように、当接部材４２は、筒部４３と、筒部４３の外周面に設けられた安全ボタン４５とを備える。筒部４３は、水栓本体部５に向かった第１軸方向Ｋ１側の筒部４３の端部から突出する突起４３Ａを有する。突起４３Ａは、後述のようにストッパー部材９の突起３１Ａに当接すると、グリップ部材４１の回転を規制する。安全ボタン４５は、グリップ部材４１の回転規制、即ち水栓１の上限温度を解除するための操作部材である。安全ボタン４５は、温調ハンドル４Ａの径方向に突出しており、安全ボタン４５の押圧方向Ｌに移動可能である。 The abutment member 42 is a member disposed inside the grip member 41 and restricts the rotation of the grip member 41. The abutment member 42 restricts the rotation of the grip member 41, so that the upper limit temperature of hot water discharged from the faucet 1 can be set. As shown in FIG. 11, the abutment member 42 includes a tubular portion 43 and a safety button 45 provided on the outer peripheral surface of the tubular portion 43. The tubular portion 43 has a protrusion 43A protruding from the end of the tubular portion 43 on the first axial direction K1 side toward the faucet main body 5. When the protrusion 43A abuts against the protrusion 31A of the stopper member 9 as described below, it restricts the rotation of the grip member 41. The safety button 45 is an operating member for releasing the restriction on the rotation of the grip member 41, i.e., the upper limit temperature of the faucet 1. The safety button 45 protrudes in the radial direction of the temperature control handle 4A and can be moved in the pressing direction L of the safety button 45.

当接部材４２は、ストッパー部材９より低い曲げ弾性率を有する材料で形成される。このような構成により、ストッパー部材９の突起３１Ａ、３１Ｂと当接部材４２の突起４３Ａとの当接した場合、当接部材４２が優先的に摩耗する。当接部材４２を容易に交換できるため、水栓１の整備性が向上する。当接部材４２は、例えば、ＰＯＭで形成される。 The abutment member 42 is formed of a material having a lower flexural modulus than the stopper member 9. With this configuration, when the protrusions 31A, 31B of the stopper member 9 come into contact with the protrusion 43A of the abutment member 42, the abutment member 42 wears preferentially. The abutment member 42 can be easily replaced, improving the maintainability of the faucet 1. The abutment member 42 is formed of, for example, POM.

続いて、図１２を参照しながら、温調ハンドル４Ａの動作について説明する。図１２は、温調ハンドル４Ａの断面図である。 Next, the operation of the temperature control handle 4A will be described with reference to Figure 12. Figure 12 is a cross-sectional view of the temperature control handle 4A.

［動作］
水栓１の使用者が吐水される湯水の温度を変更するため、温調ハンドル４Ａを回転させる。下記において、湯水の温度を増加させる例について説明する。 [Action]
A user of the faucet 1 rotates the temperature control handle 4A to change the temperature of the hot and cold water being discharged. An example of increasing the temperature of the hot and cold water will be described below.

湯水の温度を増加させるため、温調ハンドル４Ａは第１周方向Ｍ１に回転される。図１２に示すように、温調ハンドル４Ａを第１周方向Ｍ１において、ストッパー部材９の突起３１Ａの端面Ｒ１に当接する第１回転規制位置Ｐ１まで回転させる。第１回転規制位置Ｐ１において、ストッパー部材９の突起３１Ａは、第１周方向Ｍ１における温調ハンドル４Ａのさらなる回転を規制する。温調ハンドル４Ａの第１回転規制位置Ｐ１は、予め設定されたある上限温度に対応し、突起３１Ａが突起４２Ａに当接されると、上限温度以上の温度の湯水は吐水されない。 To increase the temperature of the hot and cold water, the temperature control handle 4A is rotated in a first circumferential direction M1. As shown in FIG. 12, the temperature control handle 4A is rotated in the first circumferential direction M1 to a first rotation restriction position P1 where it abuts against the end face R1 of the protrusion 31A of the stopper member 9. At the first rotation restriction position P1, the protrusion 31A of the stopper member 9 restricts further rotation of the temperature control handle 4A in the first circumferential direction M1. The first rotation restriction position P1 of the temperature control handle 4A corresponds to a preset upper limit temperature, and when the protrusion 31A abuts against the protrusion 42A, hot and cold water at a temperature above the upper limit temperature is not discharged.

上限温度を解除するためには、安全ボタン４５（図１１）を押圧方向Ｌに押し込む。安全ボタン４５の操作によって、当接部材４２の突起４３Ａは、矢印Ｓ１に沿って、径方向内側に移動し、ストッパー部材９の突起３１Ａに当接しなくなる。これにより、温調ハンドル４Ａを第１周方向Ｍ１にさらに回転することが可能になり、上限温度を解除できる。 To release the upper temperature limit, the safety button 45 (Figure 11) is pressed in the pressing direction L. By operating the safety button 45, the protrusion 43A of the abutment member 42 moves radially inward along the arrow S1 and no longer abuts against the protrusion 31A of the stopper member 9. This makes it possible to further rotate the temperature control handle 4A in the first circumferential direction M1, and release the upper temperature limit.

第１回転規制位置Ｐ１から温調ハンドル４Ａを第１周方向Ｍ１にさらに回転させると、突起４３Ａは点線で示す第２回転規制位置Ｐ２まで移動し、ストッパー部材９の突起３１Ｂの端面Ｒ２に当接する。第２回転規制位置Ｐ２において、第１周方向Ｍ１における温調ハンドル４Ａのさらなる回転は規制され、第２回転規制位置Ｐ２に対応する上限温度以上の温度の湯水は吐水されない。安全ボタン４５によって、温調ハンドル４Ａの回転規制を解除した場合においても、温調ハンドル４Ａの回転には最終的な上限が存在する。そのため、水栓１から過度に高温な湯水が吐水されることなく、水栓１の安全性が確保される。 When the temperature control handle 4A is further rotated in the first circumferential direction M1 from the first rotation restriction position P1, the protrusion 43A moves to the second rotation restriction position P2 indicated by a dotted line and abuts against the end face R2 of the protrusion 31B of the stopper member 9. At the second rotation restriction position P2, further rotation of the temperature control handle 4A in the first circumferential direction M1 is restricted, and hot water at a temperature equal to or higher than the upper limit temperature corresponding to the second rotation restriction position P2 is not dispensed. Even when the rotation restriction of the temperature control handle 4A is released by the safety button 45, there is a final upper limit to the rotation of the temperature control handle 4A. Therefore, excessively hot water is not dispensed from the faucet 1, and the safety of the faucet 1 is ensured.

また、上記の動作、即ち温調ハンドル４Ａの回転において、カラー部材１０の配置によって、ストッパー部材９が、例えば、温調ハンドル４Ａと前面カバー６との間の隙間から視認されることは防止される。 In addition, during the above operation, i.e., rotation of the temperature control handle 4A, the arrangement of the collar member 10 prevents the stopper member 9 from being visible, for example, through the gap between the temperature control handle 4A and the front cover 6.

上記の説明をまとめて、本開示の特徴を述べる。 The above explanations are summarized below to describe the features of this disclosure.

吐水される湯水に対して上限温度を設けた従来の水栓において、上限温度を規定するストッパーが摩耗する可能性がある。よって、ストッパーが摩耗した場合、温度調節機能の維持が困難となる。 In conventional faucets that set an upper limit temperature for hot and cold water that is discharged, the stopper that determines the upper limit temperature can wear out. Therefore, if the stopper wears out, it becomes difficult to maintain the temperature adjustment function.

一方で、本開示の水栓１は、ストッパー部材９とカラー部材１０との２つの異なる部材を設ける。ストッパー部材９はカラー部材１０の内側に配置され、外部からの視認性が抑制される一方、カラー部材１０は露出する。このように部材を分けることによって、ストッパー部材９とカラー部材１０とを、それぞれの機能及び配置に適した材料により形成することができる。ストッパー部材９が視認されないため、意匠性を考慮する必要なく、耐摩耗性を優先してストッパー部材９の材料を選択することができる。特に、ストッパー部材９をカラー部材１０よりも曲げ弾性率の高い材料により形成することで、ストッパー部材９の耐摩耗性を向上させることができる。一方で、カラー部材１０は回転する温調ハンドル４Ａに当接されないため、カラー部材１０の材料において、過度な強度を求めない。したがって、カラー部材１０はストッパー部材９よりも曲げ弾性率の低い材料により形成することで、表面特性が良好な材料により形成し、水栓１の意匠性を向上できる。 On the other hand, the faucet 1 of the present disclosure is provided with two different members, a stopper member 9 and a collar member 10. The stopper member 9 is arranged inside the collar member 10, suppressing its visibility from the outside, while the collar member 10 is exposed. By separating the members in this way, the stopper member 9 and the collar member 10 can be formed from materials suitable for their respective functions and arrangements. Since the stopper member 9 is not visible, the material of the stopper member 9 can be selected with a priority on wear resistance without having to consider design. In particular, by forming the stopper member 9 from a material with a higher bending modulus than the collar member 10, the wear resistance of the stopper member 9 can be improved. On the other hand, since the collar member 10 is not abutted against the rotating temperature control handle 4A, excessive strength is not required for the material of the collar member 10. Therefore, by forming the collar member 10 from a material with a lower bending modulus than the stopper member 9, it is possible to form it from a material with good surface properties and improve the design of the faucet 1.

さらに、カラー部材１０は、前面カバー６と背面カバー７とを支持するフランジ部３５を有する。そのため、カラー部材１０は、前面カバー６と背面カバー７と併せてストッパー部材９を完全に覆う外観部分を形成することができ、ストッパー部材９の露出はさらに抑制される。 In addition, the collar member 10 has a flange portion 35 that supports the front cover 6 and the rear cover 7. Therefore, the collar member 10, together with the front cover 6 and the rear cover 7, can form an exterior portion that completely covers the stopper member 9, further reducing exposure of the stopper member 9.

上述により、本開示の水栓１において、水栓１の意匠性を損なわず、温度調節に係るストッパー部材９の寿命を向上できる。 As described above, the faucet 1 of the present disclosure can improve the lifespan of the stopper member 9 related to temperature regulation without compromising the design of the faucet 1.

［効果］
実施形態に係る水栓１によれば、以下の効果を奏することができる。 [effect]
The faucet 1 according to the embodiment can provide the following effects.

実施形態に係る水栓１は、湯水混合弁２０と、主管部１２と、ハンドルユニット４と、ストッパー部材９と、カラー部材１０と、を備える。湯水混合弁２０は、湯及び水を混合する。主管部１２には、湯水混合弁２０が軸方向Ｋに沿って内部に取り付けられる。ハンドルユニットの温調ハンドル４Ａは、主管部１２の端部に配置され、湯水混合弁２０に連結される。ストッパー部材９は、主管部１２とハンドルユニット４との間で主管部１２の端部に取り付けられ、ハンドルユニット４の温調ハンドル４Ａの回転規制を行う。カラー部材１０は、ストッパー部材９を覆うように主管部１２の端部に取り付けられ、ハンドルユニット４の温調ハンドル４Ａに対して露出する露出部３０を有する。カラー部材１０は、ストッパー部材９とは異なる部材である。 The faucet 1 according to the embodiment includes a hot and cold water mixing valve 20, a main pipe 12, a handle unit 4, a stopper member 9, and a collar member 10. The hot and cold water mixing valve 20 mixes hot water and cold water. The hot and cold water mixing valve 20 is attached to the inside of the main pipe 12 along the axial direction K. The temperature control handle 4A of the handle unit is disposed at the end of the main pipe 12 and is connected to the hot and cold water mixing valve 20. The stopper member 9 is attached to the end of the main pipe 12 between the main pipe 12 and the handle unit 4, and regulates the rotation of the temperature control handle 4A of the handle unit 4. The collar member 10 is attached to the end of the main pipe 12 so as to cover the stopper member 9, and has an exposed portion 30 exposed to the temperature control handle 4A of the handle unit 4. The collar member 10 is a member different from the stopper member 9.

このような構成によって、ストッパー部材９とカラー部材１０とは互いから独立した部材であって、異なる材料で形成することができる。ストッパー部材９を高い耐摩耗性を有する材料で形成し、カラー部材１０を高い意匠性を有する材料で形成し、ストッパー部材９の寿命の向上と、カラー部材１０の意匠性の向上とを両立させた設計が可能になる。よって、温度調節に係る部材の設計自由度を向上できる。 With this configuration, the stopper member 9 and the collar member 10 are independent members and can be made of different materials. By forming the stopper member 9 from a material with high abrasion resistance and the collar member 10 from a material with high designability, it becomes possible to design the stopper member 9 to have an improved lifespan and the collar member 10 to have an improved designability. This allows for greater freedom in designing the members related to temperature regulation.

また、実施形態に係る水栓１では、ストッパー部材９は、カラー部材１０より高い曲げ弾性率を有する。 In addition, in the faucet 1 according to the embodiment, the stopper member 9 has a higher bending elasticity modulus than the collar member 10.

このような構成によって、ストッパー部材９はカラー部材１０より高い耐摩耗性を有する。これにより、ストッパー部材９をカラー部材１０と同じ材料で形成する場合と比較して、ストッパー部材９の摩耗を抑制し、ストッパー部材９の寿命を向上できる。特に、ストッパー部材９において、温調ハンドル４Ａに当接する突起３１Ａの摩耗を抑制することで、温調ハンドル４Ａの回転を規制する機能を維持することができる。一方で、筒部３４を有するカラー部材１０の曲げ弾性率が低いため、及びストッパー部材９が筒部３４に覆われ、ストッパー部材９の露出が防止されているため、水栓１の意匠性を向上させることができる。 This configuration gives the stopper member 9 higher wear resistance than the collar member 10. This reduces wear on the stopper member 9 and improves its lifespan compared to when the stopper member 9 is made of the same material as the collar member 10. In particular, by reducing wear on the protrusion 31A that contacts the temperature control handle 4A in the stopper member 9, the function of restricting the rotation of the temperature control handle 4A can be maintained. On the other hand, because the bending modulus of elasticity of the collar member 10 having the tubular portion 34 is low, and because the stopper member 9 is covered by the tubular portion 34 and prevented from being exposed, the design of the faucet 1 can be improved.

また、実施形態に係る水栓１では、カラー部材１０は、筒部３４（第１筒部）を有する。ストッパー部材９は、筒部３４の内部に配置される筒部３１（第２筒部）を有し、筒部３１の外周面は、筒部３４の内周面に対向する。 In the faucet 1 according to the embodiment, the collar member 10 has a tubular portion 34 (first tubular portion). The stopper member 9 has a tubular portion 31 (second tubular portion) that is disposed inside the tubular portion 34, and the outer peripheral surface of the tubular portion 31 faces the inner peripheral surface of the tubular portion 34.

このような構成によって、ストッパー部材９の筒部３１がカラー部材１０の筒部３４の内側に配置されるため、筒部３１の露出を防止し、ストッパー部材９の材料の選択により水栓１の意匠性が損なわれることを防止することができる。 With this configuration, the tubular portion 31 of the stopper member 9 is positioned inside the tubular portion 34 of the collar member 10, preventing the tubular portion 31 from being exposed and preventing the design of the faucet 1 from being compromised by the selection of the material for the stopper member 9.

また、実施形態に係る水栓１は、主管部１２を覆う前面カバー６及び背面カバー７（本体カバー）をさらに有する。ストッパー部材９は、筒部３１の端部から主管部１２に向かって延び、筒部３４から突出する筒部３２（第３筒部）をさらに有する。前面カバー６及び背面カバー７は、筒部３４の端部に取り付けられ、筒部３２を覆う。 The faucet 1 according to the embodiment further includes a front cover 6 and a back cover 7 (main body cover) that cover the main pipe 12. The stopper member 9 extends from the end of the tube portion 31 toward the main pipe portion 12 and further includes a tube portion 32 (third tube portion) that protrudes from the tube portion 34. The front cover 6 and the back cover 7 are attached to the end of the tube portion 34 and cover the tube portion 32.

このような構成によって、ストッパー部材９の筒部３２が前面カバー６及び背面カバー７に覆われているため、ストッパー部材９の露出をさらに防止することができる。 With this configuration, the tubular portion 32 of the stopper member 9 is covered by the front cover 6 and the rear cover 7, further preventing the stopper member 9 from being exposed.

また、実施形態に係る水栓１では、カラー部材１０は、爪部３４Ａ（第１爪部）を有し、ストッパー部材９は、爪部３４Ａが挿入される孔部３３Ａ（第１凹部）を有する。 In addition, in the faucet 1 according to the embodiment, the collar member 10 has a claw portion 34A (first claw portion), and the stopper member 9 has a hole portion 33A (first recess) into which the claw portion 34A is inserted.

このような構成によって、ストッパー部材９とカラー部材１０とを互いに安定的に嵌合することができる。 This configuration allows the stopper member 9 and the collar member 10 to be stably fitted together.

また、実施形態に係る水栓１では、カラー部材１０は、爪部３４Ａと異なる爪部３４Ｂ（第２爪部）を有する。ストッパー部材９は、爪部３４Ｂが挿入される孔部３３Ｃ（第２凹部）を有する。爪部３４Ａと爪部３４Ｂとは異なる寸法を有する。 In addition, in the faucet 1 according to the embodiment, the collar member 10 has a claw portion 34B (second claw portion) that is different from the claw portion 34A. The stopper member 9 has a hole portion 33C (second recess) into which the claw portion 34B is inserted. The claw portion 34A and the claw portion 34B have different dimensions.

このような構成によって、ストッパー部材９とカラー部材１０とを互いにさらに安定的に嵌合することができる。また、爪部３４Ａと爪部３４Ｂとの寸法が異なるため、ストッパー部材９とカラー部材１０とにおいて、誤った回転位置での取付を防止することができる。 This configuration allows the stopper member 9 and collar member 10 to be fitted together more stably. In addition, because the claw portions 34A and 34B have different dimensions, the stopper member 9 and collar member 10 can be prevented from being attached in the wrong rotational position.

また、実施形態に係る水栓１では、カラー部材１０は、主管部１２の外周面に嵌合する爪部３６（第３爪部）を有する。ストッパー部材９は、爪部３６を通す切欠き部３２Ａを設け、主管部１２の外周面に形成される溝に挿入される凸部３２Ｂを有する。 In addition, in the faucet 1 according to the embodiment, the collar member 10 has a claw portion 36 (third claw portion) that fits into the outer circumferential surface of the main pipe portion 12. The stopper member 9 has a notch portion 32A through which the claw portion 36 passes, and has a protrusion portion 32B that is inserted into a groove formed in the outer circumferential surface of the main pipe portion 12.

このような構成によって、カラー部材１０と主管部１２とを互いに安定的に嵌合することができる。爪部３６が切欠き部３２Ａを通ることによって、ストッパー部材９は、カラー部材１０と主管部１２と間に把持することができる。また、切欠き部３２Ａによって、径方向に突出させることなく爪部３６を設けることができ、水栓１の省スペース化を実現することができる。さらに、凸部３２Ｂによって、主管部１２に対して、ストッパー部材９を位置決めすることができる。 This configuration allows the collar member 10 and the main pipe 12 to be stably fitted together. The claws 36 pass through the notches 32A, allowing the stopper member 9 to be gripped between the collar member 10 and the main pipe 12. The notches 32A also allow the claws 36 to be provided without protruding radially, allowing the faucet 1 to take up less space. Furthermore, the protrusions 32B allow the stopper member 9 to be positioned relative to the main pipe 12.

また、実施形態に係る水栓１では、前面カバー６及び背面カバー７は互いに嵌合する。カラー部材１０は、前面カバー６と背面カバー７とによって挟まれるフランジ部３５を有する。 In addition, in the faucet 1 according to the embodiment, the front cover 6 and the rear cover 7 fit together. The collar member 10 has a flange portion 35 that is sandwiched between the front cover 6 and the rear cover 7.

このような構成によって、カラー部材１０のフランジ部３５を介して、前面カバー６及び背面カバー７を主管部１２に取り付けることができる。 With this configuration, the front cover 6 and rear cover 7 can be attached to the main pipe section 12 via the flange section 35 of the collar member 10.

また、実施形態に係る水栓１では、ストッパー部材９は、カラー部材１０より高い引張強度を有する。 In addition, in the faucet 1 according to the embodiment, the stopper member 9 has a higher tensile strength than the collar member 10.

このような構成によって、ストッパー部材９をカラー部材１０と同じ材料で形成する場合と比較して、ストッパー部材９の摩耗をさらに抑制することができる。 This configuration further reduces wear on the stopper member 9 compared to when the stopper member 9 is made of the same material as the collar member 10.

また、実施形態に係る水栓１では、カラー部材１０はＡＢＳで形成され、ストッパー部材９はＰＰＳで形成される。 In addition, in the faucet 1 according to the embodiment, the collar member 10 is made of ABS, and the stopper member 9 is made of PPS.

このような構成によって、カラー部材１０の表面において、成形時に発生し得るフローマークの形成を抑制し、水栓１の意匠性を向上させることができる。また、ストッパー部材９をカラー部材１０と同じ材料で形成する場合と比較して、ストッパー部材９の摩耗をさらに抑制することができる。 This configuration can suppress the formation of flow marks on the surface of the collar member 10 that may occur during molding, improving the design of the faucet 1. In addition, wear on the stopper member 9 can be further suppressed compared to when the stopper member 9 is formed from the same material as the collar member 10.
