Description

本発明は、水栓本体と、壁面に設けられた給水口と前記水栓本体とを接続する水栓脚部材と、を有する水栓装置に関する発明である。   The present invention relates to a faucet device having a faucet body, a faucet leg member connecting a faucet provided on a wall surface and the faucet body.

従来の水栓装置200は、図5、図6に示すように主として水栓本体210と水栓脚部材220で構成されている。
水栓脚部材220は略L字形状を有する水栓脚本体221に水栓本体210と接続するための袋ナット222を介して袋ナット取付部材223が螺合されている。これによって、袋ナット222が回転自在に取り付けられるとともに水栓脚本体221からの脱落が防止されるようになっている。
そして、水栓装置200は、壁面230の裏に配設された給水管231、給湯管232の端部に取り付けられた配管継手233の給水口234に水栓脚本体221の一端に設けた雄螺子部224を螺合するとともに、袋ナット222を水栓本体210の背面側に設けられた水栓本体接続部211に螺合して取り付けられるものである。
The conventional faucet device 200 mainly comprises a faucet body 210 and a faucet leg member 220 as shown in FIGS.
The faucet leg member 220 is screwed with a cap nut attachment member 223 through a cap nut 222 for connecting to the faucet body 210 to a faucet leg main body 221 having a substantially L shape. Accordingly, the cap nut 222 is rotatably attached and is prevented from dropping from the faucet leg main body 221.
The faucet device 200 is provided with a male faucet leg 221 provided at one end of the faucet leg body 221 at the water supply port 234 of the pipe joint 233 attached to the end of the water supply pipe 231 and the hot water supply pipe 232 disposed on the back of the wall 230. The screw portion 224 is screwed together, and the cap nut 222 is screwed and attached to the faucet body connecting portion 211 provided on the back side of the faucet body 210.

このような水栓装置200の場合、前記袋ナット222の前記水栓脚本体221からの脱落防止強度が高め易く、図7に示すような、施工誤差などで、本来壁面230に垂直が望ましい給水口234の中心軸235が垂直でなかったり、本来水側と湯側で同一が望ましい給水口234の前出寸法236が水側と湯側で異なることによって、前記給水口234の中心軸235と袋ナットの中心軸225が平行でない状態で取り付けられて前記袋ナット222を脱落させようとする強いこじり力が加わる場合にも、前記水栓本体210と前記水栓脚部材220とを確実に固定することが出来る利点がある。
また、前記袋ナット222の内径が水栓本体接続部211の外径に対して最小限の大きさで済む為、本来相反する前記水栓本体210と前記水栓脚部材220との接続部における通水路(図示しない)の拡大と、コンパクトな意匠とを両立し易くなる利点がある。以上、2つの利点により、この水栓装置200は広く用いられている。
In the case of such a faucet device 200, the strength to prevent the cap nut 222 from falling off from the faucet leg main body 221 can be easily increased, and the water supply that is preferably perpendicular to the wall surface 230 due to construction errors as shown in FIG. The central axis 235 of the water supply port 234 is different from the central axis 235 of the water supply port 234 because the central axis 235 of the water supply port 234 is not vertical, or the front-out dimension 236 of the water supply port 234 is preferably the same on the water side and hot water side. The faucet body 210 and the faucet leg member 220 are securely fixed even when a strong twisting force is applied to cause the cap nut 222 to fall off when the cap nut center shaft 225 is not parallel. There are advantages that can be done.
In addition, since the inner diameter of the cap nut 222 needs to be a minimum size with respect to the outer diameter of the faucet body connecting portion 211, the connecting portion between the faucet body 210 and the faucet leg member 220 that are inherently contradictory to each other. There is an advantage that it is easy to achieve both expansion of a water passage (not shown) and a compact design. As described above, the faucet device 200 is widely used due to the two advantages.

しかし、このような構成の水栓装置200の場合、前記袋ナット222の前記水栓脚本体221への取り付けの際に、前記袋ナット取付部材223を水栓脚本体221に螺合させる工程が発生する上、ゆるみを防止する為に工具を使用して高い締め付けトルクを付加する、又はゆるみ防止剤を塗布する等、手間が掛かるという問題があった。
また、前記螺合部分からの漏水を防止する為に、別に水密処理を施す必要があり、該処理に手間が掛かる上に、作業者の習熟度や使用する水密剤の品質等によって水密性が左右される為に水密信頼性が低下するという問題があった。
However, in the case of the faucet device 200 having such a configuration, when attaching the cap nut 222 to the faucet leg main body 221, there is a step of screwing the cap nut attaching member 223 into the faucet leg main body 221. In addition, there is a problem that it takes time and effort to apply a high tightening torque by using a tool to prevent loosening or to apply a loosening prevention agent.
In addition, in order to prevent water leakage from the threaded portion, it is necessary to perform a separate watertight treatment. In addition to the time and effort required for the treatment, the watertightness depends on the proficiency of the operator and the quality of the watertight agent used. There is a problem in that the reliability of watertightness is reduced due to the influence.

該問題を解決する手段として、図8に示すような、水栓脚部材320を前述のように袋ナット取付部と水栓脚部材本体とに分割せずに、一体的に構成した水栓脚本体321のものが知られている。
この場合、水栓脚部材320は平面断面が略クランク状に形成された水栓脚本体321の一端に給水口234に接続される雄螺子部322、他端には袋ナット323を係止する係止部324が形成され、係止部324の外周にはリング状の溝326が設けられている。
リング状の溝326には略C字形状で弾性を有する開口リング325が装着される。
さらに、袋ナット323の底部には外側から内側に向けて縮径された開口部323b、内周部には開口リング係止部323a及び雌螺子部(図示しない)が設けられている。
そして、水栓脚本体321のリング状の溝326に開口リング325を取り付けた後、袋ナット323を係止部324に押込むことにより開口リング325がリング状の溝326方向に撓み、所定の位置まで押込むと袋ナット323に設けた開口リング係止部323aに開口リング325が係止され、水栓脚本体321に袋ナット323が取り付けられて水栓脚部材320が形成される。(例えば、特許文献1参照。)
As means for solving the problem, the faucet leg member 320 as shown in FIG. 8 is integrally formed without dividing the faucet leg member 320 into the cap nut mounting portion and the faucet leg member main body as described above. The thing of the main body 321 is known.
In this case, the faucet leg member 320 has a male screw part 322 connected to the water supply port 234 at one end of the faucet leg main body 321 having a substantially crank-shaped cross section, and a cap nut 323 at the other end. A locking portion 324 is formed, and a ring-shaped groove 326 is provided on the outer periphery of the locking portion 324.
An opening ring 325 having a substantially C shape and elasticity is attached to the ring-shaped groove 326.
Furthermore, the bottom part of the cap nut 323 is provided with an opening 323b whose diameter is reduced from the outside to the inside, and an opening ring locking part 323a and a female screw part (not shown) are provided on the inner peripheral part.
Then, after attaching the opening ring 325 to the ring-shaped groove 326 of the faucet leg main body 321, the opening ring 325 is bent in the direction of the ring-shaped groove 326 by pushing the cap nut 323 into the locking portion 324, When pushed to the position, the opening ring 325 is locked to the opening ring locking portion 323a provided on the cap nut 323, and the cap nut 323 is attached to the faucet leg main body 321 to form the faucet leg member 320. (For example, refer to Patent Document 1.)

このような場合、前記袋ナット323の水栓脚本体321への取り付けが、前述の水栓脚本体221に比較して簡便であり、また、一体的に構成されていることから水密信頼性も高いという利点がある。また前述の水栓脚本体221同様に、前記袋ナット323の内径が前記水栓本体接続部311の外径に対して、最小限の大きさで済む為、接続部における通水路の拡大と、コンパクトな意匠とを両立し易い。   In such a case, attachment of the cap nut 323 to the faucet leg main body 321 is simpler than the faucet leg main body 221 described above, and since it is configured integrally, the watertight reliability is also improved. There is an advantage of high. Similarly to the faucet leg main body 221 described above, the inner diameter of the cap nut 323 can be minimized with respect to the outer diameter of the faucet main body connection part 311, It is easy to achieve a compact design.

しかし、このような水栓装置300の場合、施工誤差などによって給水口の中心軸と袋ナットの中心軸が平行でない状態で取り付けられて前記袋ナット323を脱落させようとする強いこじり力が加わる場合に、袋ナット323が脱落して漏水を引き起こす等の問題があった。これは図9に示すように、前記袋ナット323を前記水栓本体310に固定の為にa方向に締め込むのに伴って生じる前記開口リング325に加わるb方向のせん断方向の荷重によって、前記開口リング325がc方向である前記リング状の溝部326に押し戻されて前記開口リング係止部323aよりはずれることによって生じる(図9(B))。実際の施工現場においては前記水栓本体310と前記水栓脚部材320とが施工誤差等により傾いて取り付けられることは不可避な為、この問題によりこの水栓装置は広く用いられていない。

However, in the case of such a faucet device 300, due to a construction error or the like, it is attached in a state where the central axis of the water inlet and the central axis of the cap nut are not parallel, and a strong twisting force is applied to drop the cap nut 323. In such a case, there is a problem that the cap nut 323 is dropped to cause water leakage. As shown in FIG. 9, this is due to the load in the shear direction in the b direction applied to the opening ring 325 generated when the cap nut 323 is fastened in the direction a to fix the cap nut 323 to the faucet body 310. This is caused by the opening ring 325 being pushed back by the ring-shaped groove 326 in the c direction and being displaced from the opening ring locking portion 323a (FIG. 9B). In an actual construction site, it is inevitable that the faucet body 310 and the faucet leg member 320 are attached with inclination due to construction errors or the like, so this faucet device is not widely used due to this problem.
JP-A-8-134967 (FIG. 1)

本発明は、上記問題を解決するためになされたもので、本発明の課題は、水栓本体と、壁面に設けられた給水口と前記水栓本体とを接続する水栓脚部材と、を有する水栓装置において、施工誤差などによって給水口の中心軸と袋ナットの中心軸が平行でない状態で取り付けられる場合でも、十分な固定強度を得ることである。   The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a faucet body, a faucet leg member for connecting a faucet body provided on a wall surface and the faucet body. In the water faucet device, it is necessary to obtain a sufficient fixing strength even when the central axis of the water supply port and the central axis of the cap nut are not parallel due to construction errors.

上記目的を達成するために請求項1記載の発明によれば、吐水口が設けられた水栓本体と、壁面に設けられた給水口と前記水栓本体とを接続する水栓脚部材と、を有する水栓装置であって、前記水栓本体と接続される前記水栓脚部材の外周には、リング状の溝と、このリング状の溝に装着した略C字形状の弾性を有する開口リングと、この開口リングによって回転可能に抜け止め保持された袋ナットとを設け、該袋ナットを前記水栓本体に螺合することにより前記水栓本体と前記水栓脚部材とが接続された水栓装置において、前記リング状の溝は、前記水栓本体側に設けられた第一溝部と、この第一溝部より外径が小さく前記給水口側に設けられた第二溝部を有し、前記袋ナット内周には、円筒溝状の開口リング係止部を有し、前記第二溝部に設けられた前記開口リングが前記開口リング係止部に係止されることにより、前記袋ナットは、前記水栓脚部材に回転可能に抜け止め保持されると共に、前記袋ナットを前記水栓本体に螺合させて前記水栓本体の方向に移動させることにより、前記開口リングが前記開口リング係止部に係止された状態で前記第一溝部へ移動可能し、前記第一溝部の外周面と前記開口リング係止部の内周面とによって狭着されることを特徴とする水栓装置。とした。
これにより、前記袋ナットを強く前記水栓本体に締め込んだ場合に、該締め込みに伴って前記開口リングに加わるせん断方向の荷重によって、前記開口リングが前記溝部に押し戻されようとしても、前記開口リングが前記第一溝部の外周面と前記開口リング係止部の内周面とによって狭着されているので、前記開口リング係止部よりはずれるまで押し戻されることを防ぎ、施工誤差などによって給水口の中心軸と袋ナットの中心軸が平行でない状態で取り付けられて前記袋ナットを脱落させようとする強いこじり力が加わる場合でも、袋ナットが脱落する事無く水栓本体に対する十分な固定強度を得ることを可能とした。
また、前記袋ナットの中心軸と垂直方向のガタを大きく取ることが可能となり、より施工誤差に影響を受けず、安定した施工が可能となる。
In order to achieve the above object, according to the invention of claim 1, a faucet body provided with a water outlet, a faucet leg member connecting the water faucet provided on the wall surface and the faucet body, A faucet device having a ring-shaped groove on the outer periphery of the faucet leg member connected to the faucet body, and a substantially C-shaped elastic opening attached to the ring-shaped groove. A ring nut and a cap nut rotatably held by the opening ring are provided, and the faucet body and the faucet leg member are connected by screwing the cap nut into the faucet body. In the faucet device, the ring-shaped groove has a first groove portion provided on the faucet body side and a second groove portion provided on the water supply port side having an outer diameter smaller than the first groove portion, The inner periphery of the cap nut has a cylindrical groove-shaped opening ring locking portion, and the second groove portion When the provided opening ring is engaged with the opening ring engaging portion, the cap nut is rotatably held by the faucet leg member, and the cap nut is attached to the faucet body. The opening ring can be moved to the first groove portion in a state where the opening ring is locked to the opening ring locking portion, and the outer periphery of the first groove portion can be moved. faucet apparatus characterized by being narrow worn by the surface and the inner peripheral surface of the opening ring engaging portion. It was.
Thereby, when the cap nut is firmly tightened to the faucet body, the opening ring is pushed back into the groove portion by a load in a shearing direction applied to the opening ring along with the tightening. Since the opening ring is closely attached by the outer peripheral surface of the first groove portion and the inner peripheral surface of the opening ring locking portion , it is prevented from being pushed back until it comes off from the opening ring locking portion , Even if the center axis of the mouth and the center axis of the cap nut are not parallel and a strong twisting force is applied to drop the cap nut, sufficient fixing strength to the faucet body without dropping the cap nut Made it possible to obtain.
Further, it is possible to make a large play in the direction perpendicular to the center axis of the cap nut, and it is possible to perform stable construction without being affected by construction errors.

請求項2記載の発明によれば、前記第一溝部の深さ及び前記開口リング係止部の深さは、前記開口リングの径方向の厚みの略半分であることを特徴とする請求項1記載の水栓装置とした。
これにより、袋ナット125の水栓本体に対する固定強度は、開口リングのせん断強度に依存する為、せん断方向の荷重が開口リングのほぼ中央に加わるのが最も望ましい。このことから、第一溝部の深さは、開口リングの径方向の厚みの略半分である40%から60%が望ましい。
開口リング係止部の深さは、第一溝部の深さと同様の理由で、開口リングの中心方向の厚みの略半分である40%から60%が望ましい。
According to a second aspect of the present invention, the depth of the first groove portion and the depth of the opening ring locking portion are substantially half of the radial thickness of the opening ring. The faucet device described was used.
Thereby, since the fixing strength of the cap nut 125 with respect to the faucet body depends on the shear strength of the opening ring, it is most desirable that a load in the shearing direction is applied to the approximate center of the opening ring. For this reason, the depth of the first groove is preferably 40% to 60%, which is approximately half the radial thickness of the opening ring.
For the same reason as the depth of the first groove, the depth of the opening ring locking portion is preferably 40% to 60%, which is approximately half the thickness in the center direction of the opening ring.

本発明によれば、水栓本体と、壁面に設けられた給水口と前記水栓本体とを接続する水栓脚部材と、を有する水栓装置において、施工誤差などによって給水口の中心軸と袋ナットの中心軸が平行でない状態で取り付けられる場合でも、十分な固定強度を得ることができるという効果がある。   According to the present invention, in a faucet device having a faucet body, a faucet leg member that connects the faucet body provided on the wall surface and the faucet body, the central axis of the faucet port due to construction errors, etc. Even when the cap nut is attached in a state where the central axes are not parallel, there is an effect that a sufficient fixing strength can be obtained.

本発明に係る水栓装置の実施の形態について、添付図面を参照して説明する。   Embodiments of a faucet device according to the present invention will be described with reference to the accompanying drawings.

図1は、本発明に係る水栓装置の概念図を、図2は、本発明に係る水栓脚部材を拡大した部分構造断面を示した図である。図3は、本発明に係る水栓装置の組立て状態変化の概念を示した図である。110は吐水口が設けれた水栓本体で、120は水栓脚部材である。   FIG. 1 is a conceptual diagram of a faucet device according to the present invention, and FIG. 2 is an enlarged partial structural cross-sectional view of a faucet leg member according to the present invention. FIG. 3 is a view showing the concept of assembly state change of the faucet device according to the present invention. 110 is a faucet body provided with a water outlet, and 120 is a faucet leg member.

水栓本体110は、周知のサーモスタット式の湯水混合水栓であり、その背面側には水栓本体接続部111を有している。   The faucet body 110 is a well-known thermostat-type hot / cold water faucet, and has a faucet body connecting portion 111 on the back side thereof.

水栓脚部材120は、平面断面がクランク形状で、給水口131側の端部は雄螺子部121が設けられ、水栓本体110側の接続部122の外周にはリング状の溝123が設けられていて、そこに略C字形状の弾性を有する開口リング124が装着されており、開口リングを介して、袋ナット125が回転自在に取付けられている。(図2参照)   The faucet leg member 120 has a crank-shaped cross section, a male screw portion 121 is provided at the end on the water supply port 131 side, and a ring-shaped groove 123 is provided on the outer periphery of the connection portion 122 on the faucet body 110 side. An opening ring 124 having a substantially C-shaped elasticity is attached thereto, and a cap nut 125 is rotatably attached through the opening ring. (See Figure 2)

リング状の溝123は水栓本体110側に設けられた第一溝部123aと、この第一溝部より外径が小さく、給水口側に設けられた第二溝部123bを有する。また、第一溝部123aの深さは、開口リング124の中心方向の厚みよりも小さく形成されている。袋ナット125の水栓本体に対する固定強度は、開口リング124のせん断強度に依存する為、せん断方向の荷重が開口リングのほぼ中央に加わるのが最も望ましい。このことから、第一溝部123aの深さは、開口リング124の中心方向の厚みの略半分である40%から60%が望ましい。
第二溝部123bの深さは、開口リング124の中心方向の厚みと略同一かそれ以上とする。これより小さいと、後に説明する袋ナット取付時の開口リングの絞り動作時に開口リングが底付きを起こして袋ナットの装着が出来なくなる。(図3(A)参照)
The ring-shaped groove 123 has a first groove portion 123a provided on the faucet body 110 side and a second groove portion 123b having an outer diameter smaller than that of the first groove portion and provided on the water supply port side. Further, the depth of the first groove 123 a is formed smaller than the thickness of the opening ring 124 in the center direction. Since the fixing strength of the cap nut 125 with respect to the faucet body depends on the shear strength of the opening ring 124, it is most desirable that a load in the shear direction is applied to the approximate center of the opening ring. For this reason, the depth of the first groove 123a is preferably 40% to 60%, which is approximately half the thickness of the opening ring 124 in the center direction.
The depth of the second groove portion 123b is substantially equal to or greater than the thickness of the opening ring 124 in the center direction. If it is smaller than this, the opening ring will bottom out when the opening ring is squeezed when attaching the cap nut, which will be described later, and the cap nut cannot be attached. (See Fig. 3 (A))

開口リング124は円形で、内径が接続部123の外径より小さく、外径が接続部123の径より大きい。このとき、開口リング124の中心径と接続部123の外径が略同一となるのが望ましい。また開口リング124には、ばね鋼等の弾性に富んだ材料を用いる。   The opening ring 124 is circular and has an inner diameter smaller than the outer diameter of the connection portion 123 and an outer diameter larger than the diameter of the connection portion 123. At this time, it is desirable that the center diameter of the opening ring 124 and the outer diameter of the connection portion 123 be substantially the same. The opening ring 124 is made of a material having high elasticity such as spring steel.

袋ナット125の内周には円筒溝状の開口リング係止部125aが設けられており、開口リング係止部125aより給水口側には開口リング呼び込み用のテーパー部125bが、開口リング係止部125aより水栓本体110側には水栓本体固定用のねじ部125cが設けてある。そして、開口リング係止部125aの深さは、開口リング124の中心方向の厚みよりも小さく形成している。
開口リング係止部125aの深さは、第一溝部123aの深さと同様の理由で、開口リング124の中心方向の厚みの略半分である40%から60%が望ましい。
A cylindrical groove-shaped opening ring locking portion 125a is provided on the inner periphery of the cap nut 125, and a tapered portion 125b for calling the opening ring is provided on the water supply side of the opening ring locking portion 125a. A screw portion 125c for fixing the faucet body is provided on the faucet body 110 side from the portion 125a. And the depth of the opening ring latching | locking part 125a is formed smaller than the thickness of the center direction of the opening ring 124. FIG.
For the same reason as the depth of the first groove portion 123a, the depth of the opening ring locking portion 125a is preferably 40% to 60%, which is approximately half the thickness of the opening ring 124 in the center direction.

袋ナット125のテーパー部125bのテーパー面と、袋ナット125の中心軸との角度は45度から30度程度が望ましい。この角度が小さい程、袋ナット125挿入時に開口リング124を絞り込む時の抵抗が小さくなって袋ナットの取付け作業性が向上するが、その分袋ナット125の奥行き寸法が大きくなり、経済的にも意匠的にも不利となる。テーパー部125bの給水口側の直径は、開口リング124の外径と略同一またはそれ以上とする。これ以下だと、袋ナット125挿入時に、開口リングが袋ナットのテーパー部125bからはみ出てしまい、後に説明する開口リング124の絞り動作が行われずに作業性が悪くなる。   The angle between the tapered surface of the tapered portion 125b of the cap nut 125 and the center axis of the cap nut 125 is preferably about 45 to 30 degrees. The smaller this angle, the smaller the resistance when narrowing the opening ring 124 when the cap nut 125 is inserted, and the cap nut mounting workability is improved. However, the depth dimension of the cap nut 125 is increased correspondingly, and economically. It is also disadvantageous in terms of design. The diameter of the tapered portion 125b on the water supply port side is substantially the same as or larger than the outer diameter of the opening ring 124. If it is less than this, when the cap nut 125 is inserted, the opening ring protrudes from the taper portion 125b of the cap nut, and the opening operation of the opening ring 124, which will be described later, is not performed, resulting in poor workability.

次に水栓脚部材120への袋ナット125の取り付け手順および動作について図3を使用して説明する。   Next, the procedure and operation of attaching the cap nut 125 to the faucet leg member 120 will be described with reference to FIG.

先ず初めに、水栓脚部材120の接続部122に開口リング124を押し広げて溝123に装着する。開口リング装着後は図3(A)の状態となる。開口リング124は挿入時に押し広げても、その弾性によって装着後は初期の寸法に復元し、かつ内径が接続部122の径より小さいことから装着後に容易に脱落しない為、以降の作業性が良好である。   First, the opening ring 124 is pushed and widened on the connection part 122 of the faucet leg member 120 and attached to the groove 123. After the opening ring is mounted, the state shown in FIG. Even if the opening ring 124 is expanded at the time of insertion, the elasticity is restored to the initial dimension after mounting, and since the inner diameter is smaller than the diameter of the connecting portion 122, it does not easily fall off after mounting, so the subsequent workability is good. It is.

次に、図3(B)、(C)に示すように、袋ナット125を接続部122に挿入する。挿入を進めていくと、先に装着した開口リング124に袋ナット125に設けたテーパー部125bが接し、更に挿入を進めるとテーパーに沿って開口リング124が中心方向に絞られて、第二溝部123bに押し込まれる。この時、第二溝部123bの深さが開口リング124の中心方向の厚み以下だと絞られた開口リング124が底付きを起こし、袋ナット125を更に挿入できずに以下の動作が行われない。   Next, as shown in FIGS. 3B and 3C, the cap nut 125 is inserted into the connection portion 122. When the insertion is advanced, the tapered portion 125b provided on the cap nut 125 comes into contact with the previously installed opening ring 124, and when the insertion is further advanced, the opening ring 124 is squeezed in the center direction along the taper. It is pushed into 123b. At this time, if the depth of the second groove portion 123b is equal to or less than the thickness of the opening ring 124 in the center direction, the narrowed opening ring 124 causes bottoming, and the cap nut 125 cannot be further inserted, and the following operation is not performed. .

次に、図3(D)に示すように、更に袋ナット125の挿入を進めていくと、袋ナット125の内側に設けた開口リング係止部125aが絞られた開口リング124を通過する際に、開口リング124がその弾性で復元し、開口リング係止部125aに係止される。これによって、袋ナット125は接続部122に回転自在に取り付けられる。   Next, as shown in FIG. 3D, when the insertion of the cap nut 125 is further advanced, the opening ring locking portion 125a provided on the inner side of the cap nut 125 passes through the narrowed opening ring 124. Further, the opening ring 124 is restored by its elasticity and is locked to the opening ring locking portion 125a. Thereby, the cap nut 125 is rotatably attached to the connecting portion 122.

次に、水栓本体110に水栓脚部材120を取り付ける時の動作について同じく図3を用いて説明する。   Next, the operation when the faucet leg member 120 is attached to the faucet body 110 will be described with reference to FIG.

水栓本体110に水栓脚部材120を取り付ける為に、袋ナット125を回転させ、水栓本体接続部111に螺合し、締めこむと、図3(E)に示すように、袋ナット125が水栓本体110側に移動し、これに伴って開口リング124も第一溝部123aに移動する。よって、開口リング124が、第一溝部123aと開口リング係止部125aとによって挟着される。 In order to attach the faucet leg member 120 to the faucet body 110, the cap nut 125 is rotated, screwed into the faucet body connecting portion 111, and tightened, as shown in FIG. Moves to the faucet body 110 side, and accordingly, the opening ring 124 also moves to the first groove portion 123a. Therefore, the opening ring 124 is sandwiched between the first groove portion 123a and the opening ring locking portion 125a.

これにより、図4に示すように、前記袋ナット125を強くa方向である前記水栓本体接続部111に締め込んだ場合に、該締め込みに伴ってb方向である前記開口リング124に加わるせん断方向の荷重によって、前記開口リング124が前記溝部123に押し戻されようとしても、第一溝部123aの深さがa方向である前記開口リング124の中心方向の厚みよりも小さいことから、前記開口リング係止部125aよりはずれるまで押し戻されることを防ぎ、施工誤差などによって給水口の中心軸と袋ナットの中心軸が平行でない状態で取り付けられて前記袋ナット125を脱落させようとする強いこじり力が加わる場合でも、十分な固定強度が得られる。   As a result, as shown in FIG. 4, when the cap nut 125 is strongly tightened to the faucet body connecting portion 111 in the a direction, it is added to the opening ring 124 in the b direction along with the tightening. Even if the opening ring 124 is pushed back into the groove portion 123 by a load in the shear direction, the depth of the first groove portion 123a is smaller than the thickness in the center direction of the opening ring 124 in the a direction. A strong twisting force that prevents the cap nut 125 from falling off by being attached with the center axis of the water inlet and the center axis of the cap nut not being parallel due to construction errors, etc. Even when is added, sufficient fixing strength can be obtained.
