取付け部材１Ｃを用いて分岐栓４Ｃを水栓３に取付ける方法について説明する。
まず、図２２および図２３に示す如く、水栓本体３０の取付け部３１から前記ハンドルレバー３８、カバーケース３６、カートリッジ３５、カバーケース取付け部材３７を取外す。そして、当該水栓本体３０の取付け部３１の先端部３２に、取付け部材１Ｃを配置する。このとき、図２２から図２４に示す如く、取付け部材１Ｃの第一取付け部材１Ｃａと第二取付け部材１ＣｂとでそれぞれのＣ字状の開放側を互いに向き合させて水栓本体３０の取付け部３１の先端部３２を挟むようにして、その凸部１１を水栓本体３０の凹部３４に嵌合させる。このように、当該水栓本体３０の取付け部３１の凹部３４に、凸部１１を嵌合させることによって、取付け部材１Ｃを水栓３の取付け部３１の先端部３２に固定する。
A method for attaching the branch plug 4C to the faucet 3 using the attachment member 1C will be described.
First, as shown in FIGS. 22 and 23, the handle lever 38, the cover case 36, the cartridge 35, and the cover case attaching member 37 are removed from the attaching portion 31 of the faucet body 30. And the attachment member 1C is arrange | positioned in the front-end | tip part 32 of the attachment part 31 of the said faucet main body 30. FIG. At this time, as shown in FIGS. 22 to 24, the first attachment member 1Ca and the second attachment member 1Cb of the attachment member 1C face each other in the C-shaped open side so that the attachment portion of the faucet main body 30 faces each other. The convex portion 11 is fitted into the concave portion 34 of the faucet body 30 so as to sandwich the tip end portion 32 of 31. In this way, the fitting member 1 </ b> C is fixed to the distal end portion 32 of the mounting portion 31 of the faucet 3 by fitting the convex portion 11 into the concave portion 34 of the mounting portion 31 of the faucet body 30.
さらに、図２５に示す如く、取付け部材１Ｃが配置された水栓本体３０の取付け部３１に、分岐栓４Ｃを配置する。このとき、分岐栓４Ｃの固定ナット５０ｂを周方向に回転させて、取付け部材１Ｃの接合部２０の雄ネジと当該固定ナット５０ｂ（分岐栓４Ｃの取付け部５３Ｃ）の雌ネジとを螺合させることによって、分岐栓４Ｃの取付け部５３Ｃに取付け部材１Ｃの接合部２０を接合させる。このようにして、取付け部材１Ｃ（固定部１０および接合部２０）を用いて分岐栓４Ｃが水栓３に取付けられる。
Furthermore, as shown in FIG. 25, the branch plug 4C is arranged at the attachment portion 31 of the faucet body 30 where the attachment member 1C is arranged. At this time, the fixing nut 50b of the branch plug 4C is rotated in the circumferential direction, and the male screw of the joint portion 20 of the mounting member 1C and the female screw of the fixing nut 50b (the mounting portion 53C of the branch plug 4C) are screwed together. Thus, the joint portion 20 of the attachment member 1C is joined to the attachment portion 53C of the branch plug 4C. In this way, the branch plug 4C is attached to the faucet 3 using the attachment member 1C (fixing portion 10 and joint portion 20).
以上のように、取付け部材１Ｃは、固定部１０と接合部２０とを具備する。固定部１０は、水栓本体３０における取付け部３１の凹部３４に嵌合可能な凸部１１を有し、水栓本体３０における取付け部３１の凹部３４に前記凸部１１を嵌合させることによって前記水栓本体３０の取付け部３１に固定される。接合部２０は、分岐栓４Ｃの取付け部５３Ｃに接合可能な接合手段２１を有する。このため、取付け部材１Ｃによれば、カバーケース３６を取付けるための凹部３４を有する取付け部３１を備える水栓３であっても、当該水栓３の取付け部３１にネジを形成する加工を施すことや、水栓３の取付け部３１と分岐栓４Ｃの取付け部５３Ｃとを溶接する加工を水栓３や分岐栓４Ｃに加工を施すことなく、これに分岐栓４Ｃを取付けることができる。したがって、取付け部材１Ｃによれば、カバーケース３６を取付けるための凹部３４を有する取付け部３１を備える水栓３に、容易に分岐栓４Ｃを取付けることができる。
As described above, the attachment member 1 </ b> C includes the fixed portion 10 and the joint portion 20. The fixing portion 10 has a convex portion 11 that can be fitted into the concave portion 34 of the attachment portion 31 in the faucet body 30, and the convex portion 11 is fitted into the concave portion 34 of the attachment portion 31 in the faucet body 30. It is fixed to the attachment part 31 of the faucet body 30. The joining part 20 has joining means 21 that can be joined to the attachment part 53C of the branch plug 4C. For this reason, according to the attachment member 1C, even if the faucet 3 includes the attachment portion 31 having the recess 34 for attaching the cover case 36, the attachment portion 31 of the faucet 3 is processed to form a screw. In addition, it is possible to attach the branch plug 4C to the faucet 3 or the branch plug 4C without performing the process of welding the attachment portion 31 of the faucet 3 and the attachment portion 53C of the branch plug 4C. Therefore, according to the attachment member 1 </ b> C, the branch plug 4 </ b> C can be easily attached to the faucet 3 including the attachment portion 31 having the recess 34 for attaching the cover case 36.
また、取付け部材１Ｃを構成する第一取付け部材１Ｃａと第二取付け部材１Ｃｂとは、略円柱形状の部材をその軸心に沿って切断して互いに対称となるような側面視略Ｃ字状に形成される。このため、取付け部材１Ｃによれば、より簡易な構造で本発明に係る取付け部材を実現することができる。
Further, the first mounting member 1Ca and the second mounting member 1Cb constituting the mounting member 1C are substantially C-shaped in a side view such that a substantially cylindrical member is cut along its axis to be symmetrical with each other. It is formed. For this reason, according to the attachment member 1C, the attachment member according to the present invention can be realized with a simpler structure.
分岐栓４Ｃの固定ナット５０ｂ（分岐栓４Ｃの取付け部５３Ｃ）は、その内周面の径が、取付け部材１Ｃの外周面の径と略同一に形成されて、固定ナット５０ｂ内において取付け部材１Ｃと接合可能なように構成されている。このため、固定ナット５０ｂ（分岐栓４Ｃの取付け部５３Ｃ）に取付け部材１Ｃ（接合部２０）が接合された際には、取付け部材１Ｃ（固定部１０）は、分岐栓４Ｃの取付け部５３Ｃの内側に配置されることとなる。このように、取付け部材１Ｃの固定部１０は、分岐栓４Ｃの取付け部５３Ｃに接合部２０が接合された際に、分岐栓４Ｃの取付け部５３Ｃの内側に配置可能に構成される。したがって、分岐栓４Ｃの取付け部５３Ｃに取付け部材１Ｃ（接合部２０）が接合された際には、分岐栓４Ｃの外装部材５０（固定ナット５０ｂ）の内壁によって、固定部１０が周方向に広がって変形してその凸部１１が水栓本体３０の取付け部３１の凹部３４から脱落することが防止されることとなる。よって、取付け部材１Ｃによれば、確実に分岐栓４Ｃを水栓３に取付けた状態を保持することができる。
The fixing nut 50b of the branch plug 4C (the mounting portion 53C of the branch plug 4C) has an inner peripheral surface formed to have substantially the same diameter as the outer peripheral surface of the mounting member 1C. It can be joined with. For this reason, when the attachment member 1C (joint part 20) is joined to the fixing nut 50b (attachment part 53C of the branch plug 4C), the attachment member 1C (fixation part 10) is attached to the attachment part 53C of the branch plug 4C. It will be arranged inside. As described above, the fixing portion 10 of the attachment member 1C is configured to be disposed inside the attachment portion 53C of the branch plug 4C when the joint portion 20 is joined to the attachment portion 53C of the branch plug 4C. Therefore, when the attachment member 1C (joint part 20) is joined to the attachment part 53C of the branch plug 4C, the fixing part 10 spreads in the circumferential direction by the inner wall of the exterior member 50 (fixing nut 50b) of the branch plug 4C. Therefore, the convex portion 11 is prevented from falling off from the concave portion 34 of the attachment portion 31 of the faucet body 30. Therefore, according to the attachment member 1 </ b> C, the state in which the branch plug 4 </ b> C is attached to the faucet 3 can be reliably maintained.
