以上のようにして構成された、分岐栓本体10、外装部材20、回転部材40、および、接続部材50、を組み合わせることによって、分岐栓1が構成される。以下において、当該組み合わせの手順について具体的に説明する。   The branch plug 1 is configured by combining the branch plug main body 10, the exterior member 20, the rotating member 40, and the connection member 50 configured as described above. Below, the procedure of the said combination is demonstrated concretely.

外装本体21の第1貫通孔22と分岐栓本体10の分岐横溝15とを連通せるようにして、外装本体21に分岐栓本体10を嵌装する。このように、分岐栓本体10を嵌装することで、分岐横溝15を介して、外装本体21の第1貫通孔22と分岐栓本体10の横孔14とが連通されることとなる。この際、分岐栓本体10のOリング16・16によって、外装本体21の第1貫通孔22と分岐栓本体10の分岐横溝15とが水密的にシールされる。   The branch plug body 10 is fitted to the exterior body 21 so that the first through hole 22 of the exterior body 21 and the branch lateral groove 15 of the branch plug body 10 can communicate with each other. Thus, by fitting the branch plug main body 10, the first through hole 22 of the exterior main body 21 and the horizontal hole 14 of the branch plug main body 10 communicate with each other through the branch horizontal groove 15. At this time, the O-rings 16 and 16 of the branch plug body 10 seal the first through hole 22 of the exterior body 21 and the branch lateral groove 15 of the branch plug body 10 in a watertight manner.

次に、上方から金属素材からなるリング部材33を固定ナット30の凹部31に嵌装する。そして、前記外装本体21の下方から当該固定ナット30を嵌め、外装本体21の凹部24にリング部材33に嵌合させる。このようにして、固定ナット30は、外装本体21に係合され、また、外装本体21の下方に配置される。   Next, the ring member 33 made of a metal material is fitted into the recess 31 of the fixing nut 30 from above. Then, the fixing nut 30 is fitted from below the exterior main body 21, and the ring member 33 is fitted into the recess 24 of the exterior main body 21. In this way, the fixing nut 30 is engaged with the exterior body 21 and is disposed below the exterior body 21.

さらに、外装本体21の第1横溝23と回転部材40の第2横溝42との上下方向の位置を一致させるようにして、回転部材40の下方から係る状態の外装本体21を嵌装させる。具体的には、係る状態の外装本体21の上方から回転部材40を被せて、外装本体21の下部に当接するまで、外装本体21の中途部と固定ナット30の上部との間に形成される凹状部分に、回転部材40の小径に形成された凸状の下端部を嵌入させる。このように回転部材40に前記外装本体21を嵌装することによって、固定ナット30の上方に回転部材40は配置され、また、外装本体21の第1横溝23と回転部材40の第2横溝42とが連通することとなる。そして、当該第1横溝23と当該第2横溝42とによって外装流路25が形成され、当該外装流路25を介して、外装本体21の第1貫通孔22と回転部材40の第2貫通孔41が連通することとなる。この際、外装本体21のOリング26・26によって、外装流路25が密的にシールされる。また、回転部材40は、周方向に回転可能なように、且つ、外装本体21の中途部を嵌装可能なように、その内径が、外装本体21の中途部の外径と略同一に形成されている。このため、外装本体21が嵌装された状態においても、回転部材40は、外装本体21に対して周方向に回転可能に構成されている(図7参照)。なお、回転部材40は、その下端部で外装本体21の中途部と固定ナット30の上部との間に形成される凹状部分に案内されながら、その軸心を中心として回転することとなる。   Further, the exterior body 21 in such a state is fitted from below the rotation member 40 so that the vertical positions of the first lateral groove 23 of the exterior body 21 and the second lateral groove 42 of the rotation member 40 coincide with each other. Specifically, it is formed between the middle part of the exterior body 21 and the upper part of the fixing nut 30 until the rotating member 40 is covered from above the exterior body 21 in such a state and comes into contact with the lower part of the exterior body 21. A convex lower end portion formed in a small diameter of the rotating member 40 is fitted into the concave portion. Thus, by fitting the exterior body 21 on the rotation member 40, the rotation member 40 is disposed above the fixing nut 30, and the first lateral groove 23 of the exterior body 21 and the second lateral groove 42 of the rotation member 40 are arranged. Will communicate with each other. And the exterior flow path 25 is formed by the said 1st horizontal groove 23 and the said 2nd horizontal groove 42, and the 1st through-hole 22 of the exterior main body 21 and the 2nd through-hole of the rotation member 40 are via the said exterior flow path 25. 41 communicates. At this time, the exterior flow path 25 is tightly sealed by the O-rings 26 and 26 of the exterior body 21. Further, the inner diameter of the rotating member 40 is substantially the same as the outer diameter of the middle part of the exterior body 21 so that the rotation member 40 can be rotated in the circumferential direction and the middle part of the exterior body 21 can be fitted. Has been. For this reason, even when the exterior body 21 is fitted, the rotating member 40 is configured to be rotatable in the circumferential direction with respect to the exterior body 21 (see FIG. 7). The rotating member 40 rotates about its axis while being guided by a concave portion formed between the middle portion of the exterior body 21 and the upper portion of the fixing nut 30 at the lower end thereof.

さらに、接続部材50と係る状態の回転部材40とを接合する。具体的には、接続部材50の一端である挿入部52と回転部材40の第2貫通孔41とを直接接合する。接続部材50の挿入部52と回転部材40の第2貫通孔41との接合は、接続部材50に形成された雄ネジと、回転部材40における第2貫通孔41に形成された雌ネジとを螺合させることによって行う。この場合、接続部材50の雄ネジと第2貫通孔41の雌ネジとの間は、接着剤等のシール材を介装するなどして水密的にシールされる。このようにして、接続部材50と回転部材40とを接合することによって、接続部材50の接続流路51と回転部材40の第2貫通孔41とが連通することとなる。つまり、分岐栓本体10の水側流路12と、接続部材50の接続流路51とは、横孔14、分岐横溝15、第1貫通孔22、外装流路25、および、第2貫通孔41、を介して、連通することとなる。以上のようにして、分岐栓本体10、外装部材20、および、接続部材50等、によって分岐栓1は構成される。   Further, the connecting member 50 and the rotating member 40 in the state are joined. Specifically, the insertion portion 52 which is one end of the connection member 50 and the second through hole 41 of the rotating member 40 are directly joined. The insertion portion 52 of the connecting member 50 and the second through hole 41 of the rotating member 40 are joined by a male screw formed in the connecting member 50 and a female screw formed in the second through hole 41 of the rotating member 40. This is done by screwing. In this case, the male screw of the connection member 50 and the female screw of the second through hole 41 are sealed in a watertight manner by interposing a sealing material such as an adhesive. In this way, the connection flow path 51 of the connection member 50 and the second through hole 41 of the rotation member 40 communicate with each other by joining the connection member 50 and the rotation member 40. That is, the water-side flow path 12 of the branch plug body 10 and the connection flow path 51 of the connection member 50 are the horizontal hole 14, the branch horizontal groove 15, the first through hole 22, the exterior flow path 25, and the second through hole. 41, and communicate with each other. As described above, the branch plug 1 is constituted by the branch plug main body 10, the exterior member 20, the connection member 50, and the like.

分岐栓1は、混合水栓本体2とカートリッジ3との間に配置され、混合水栓60に取付けられる。以下において、混合水栓本体2とカートリッジ3との間に分岐栓1を配置する際の手順について具体的に説明する。   The branch plug 1 is disposed between the mixing faucet body 2 and the cartridge 3 and attached to the mixing faucet 60. Below, the procedure at the time of arrange | positioning the branch stopper 1 between the mixing faucet main body 2 and the cartridge 3 is demonstrated concretely.

まず、混合水栓本体2の上に分岐栓1を載置する。この際、混合水栓本体2内に設けられた前記湯側流路管と分岐栓本体10に形成された湯側流路11との開口位置、混合水栓本体2内に設けられた前記水側流路管と分岐栓本体10に形成された水側流路12との開口位置、および、混合水栓本体2内に設けられた前記混合液流路管と分岐栓本体10に形成された混合流路13との開口位置を、それぞれ一致させるようにして、混合水栓本体2の上に分岐栓1を載置する。係るように混合水栓本体2の上に分岐栓1を載置することで、前記湯側流路管と湯側流路11とが、前記水側流路管と水側流路12とが、および、前記混合液流路管と混合流路13とが、それぞれ連通されることとなる。つまり、混合水栓本体2の前記水側流路管と、接続部材50の接続流路51とは、水側流路12、横孔14、分岐横溝15、第1貫通孔22、外装流路25、第2貫通孔41、を介して、連通することとなる。   First, the branch plug 1 is placed on the mixing faucet body 2. At this time, the opening position of the hot water side channel pipe provided in the mixing faucet body 2 and the hot water side channel 11 formed in the branch tap body 10, the water provided in the mixing faucet body 2. The opening position of the side channel pipe and the water side channel 12 formed in the branch plug body 10, and the mixed solution channel pipe and the branch plug body 10 provided in the mixed tap body 2 are formed. The branch plug 1 is placed on the mixed water faucet body 2 so that the opening positions with the mixing flow channel 13 coincide with each other. As described above, by placing the branch plug 1 on the mixing faucet main body 2, the hot water side flow pipe and the hot water side flow path 11 are connected to each other, and the water side flow pipe and the water side flow path 12 are connected. And the said mixed liquid channel pipe and the mixed channel 13 will be connected, respectively. That is, the water-side channel pipe of the mixing faucet body 2 and the connection channel 51 of the connecting member 50 are the water-side channel 12, the lateral hole 14, the branch lateral groove 15, the first through hole 22, and the exterior channel. 25, and the second through hole 41.

次に、固定ナット30の下部を混合水栓本体2に接合させる。具体的には、固定ナット30を外装本体21に対して回転させて固定ナット30における下部の内周面に形成された雌ネジと、混合水栓本体2の上部に形成された雄ネジとを螺合させていく。当該雌ネジと雄ネジとを螺合させていくことにより、リング部材33を介して固定ナットに係合された外装本体21は、その下端部が混合水栓2の上端部に押圧されて混合水栓本体2に固定されることとなる。このとき、回転部材40は、固定ナット30に係合されず、また、下方に押圧されない、つまり、混合水栓本体2に固定されないため、係る状態においても、その軸心方向を中心として周方向に回転可能に構成されている。   Next, the lower part of the fixing nut 30 is joined to the mixing faucet body 2. Specifically, the fixing nut 30 is rotated with respect to the exterior main body 21, and a female screw formed on the inner peripheral surface of the lower portion of the fixing nut 30 and a male screw formed on the upper portion of the mixing faucet main body 2 are Screw them together. By screwing the female screw and the male screw together, the exterior body 21 engaged with the fixing nut via the ring member 33 is pressed at its lower end against the upper end of the mixing faucet 2 and mixed. It will be fixed to the faucet body 2. At this time, the rotating member 40 is not engaged with the fixing nut 30 and is not pressed downward, that is, not fixed to the mixed water faucet body 2, so even in such a state, the circumferential direction is centered on the axial direction. It is configured to be rotatable.

そして、当該分岐栓1における分岐栓本体10の上方に、カートリッジ3を載置する。 さらに、外装本体21の上部とカバーナット4とを接合する。具体的には、ハンドルレバー5が取り付けられたカバーナット4をカートリッジ3にかぶせて、カバーナット4を外装本体21の上端部に螺合する。このとき、回転部材40は、カバーナット4と接合されないため、係る状態においても、外装本体21に対して周方向に回転可能に構成されている。このようにして、分岐栓1が混合水栓60に取付けられる。   Then, the cartridge 3 is placed above the branch plug body 10 in the branch plug 1. Furthermore, the upper part of the exterior main body 21 and the cover nut 4 are joined. Specifically, the cover nut 4 to which the handle lever 5 is attached is placed on the cartridge 3, and the cover nut 4 is screwed to the upper end portion of the exterior body 21. At this time, since the rotating member 40 is not joined to the cover nut 4, even in such a state, the rotating member 40 is configured to be rotatable in the circumferential direction with respect to the exterior body 21. In this way, the branch plug 1 is attached to the mixed water tap 60.

以上のようにして、分岐栓1においては、回転部材40は、その内径が、外装本体21の中途部を嵌装可能なように、外装本体21の中途部の外径と略同一の筒形状に形成されている。そして、回転部材40には、外装本体21に対して周方向に回転可能なように、外装本体21が嵌装される。また、分岐栓1が混合水栓本体2に取付けられた状態においても、回転部材40は、混合水栓本体2に固定されず、周方向に回転可能に構成されている。また、分岐栓1にカバーナット4が取付けられた状態においても、回転部材40は、カバーナット4に接合されず、外装本体21に対して周方向に回転可能に構成されている。このため、混合水栓60に分岐栓1を取付けた状態でも、回転部材40を周方向に回転させて、回転部材40の第2貫通孔41における外周面への開口部の周方向の位置を変更することができる。したがって、例えば、当該接続部材50の周方向の位置について微調整を行う場合や、接続対象物の配置変更を行う場合等においても、固定ナット30やカバーナット4の螺合を緩めることなく、第2貫通孔41に接合された接続部材50の周方向の位置を変更することができ、接続対象物の取付け作業を容易に行うことができる。   As described above, in the branch plug 1, the rotary member 40 has a cylindrical shape that is substantially the same as the outer diameter of the midway part of the exterior body 21 so that the inside diameter can be fitted in the midway part of the exterior body 21. Is formed. The exterior body 21 is fitted to the rotating member 40 so as to be rotatable in the circumferential direction with respect to the exterior body 21. In addition, the rotating member 40 is configured not to be fixed to the mixed water faucet body 2 but to be rotatable in the circumferential direction even when the branch plug 1 is attached to the mixed water faucet body 2. Even in a state where the cover nut 4 is attached to the branch plug 1, the rotating member 40 is not joined to the cover nut 4 and is configured to be rotatable in the circumferential direction with respect to the exterior body 21. For this reason, even when the branch plug 1 is attached to the mixing faucet 60, the rotation member 40 is rotated in the circumferential direction, and the circumferential position of the opening to the outer peripheral surface of the second through hole 41 of the rotation member 40 is determined. Can be changed. Therefore, for example, even when fine adjustment is performed on the circumferential position of the connection member 50 or when the arrangement of the connection object is changed, the fixing nut 30 and the cover nut 4 are not loosened without loosening. The circumferential position of the connection member 50 joined to the two through holes 41 can be changed, and the attachment work of the connection object can be easily performed.

回転部材40は、その内径が、周方向に回転可能なように、且つ、外装本体21の中途部を嵌装可能なように、外装本体21の中途部の外径と略同一に形成されている。回転部材40の内径が、固定ナット30の少なくとも一部の内径よりも大きく、且つ、前記固定ナット30の外径より小さく形成される。そして、回転部材40は、外装本体21が嵌装された際に、固定ナット30の上方に配置される。このため、混合水栓60に分岐栓1を取付けた状態でも、回転部材40を周方向に回転させて、回転部材40の第2貫通孔41における外周面への開口部の周方向の位置を変更することができる。したがって、固定ナット30やカバーナット4の螺合を緩めることなく、第2貫通孔41に接合された接続部材50の周方向の位置を変更することができ、接続対象物の取付け作業を容易に行うことができる。また、このような分岐栓1を、簡易構造で実現することができる。また、分岐栓1が混合水栓本体2に載置された状態で、回転部材40が固定ナット30の下方に脱落することはないので、接続対象物の取付け作業をさらに容易に行うことができる。   The rotating member 40 is formed to be substantially the same as the outer diameter of the middle part of the exterior body 21 so that the inner diameter thereof can be rotated in the circumferential direction and the middle part of the exterior body 21 can be fitted. Yes. The inner diameter of the rotating member 40 is larger than the inner diameter of at least a part of the fixed nut 30 and smaller than the outer diameter of the fixed nut 30. The rotating member 40 is disposed above the fixing nut 30 when the exterior body 21 is fitted. For this reason, even when the branch plug 1 is attached to the mixing faucet 60, the rotation member 40 is rotated in the circumferential direction, and the circumferential position of the opening to the outer peripheral surface of the second through hole 41 of the rotation member 40 is determined. Can be changed. Therefore, the circumferential position of the connecting member 50 joined to the second through hole 41 can be changed without loosening the fixing nut 30 and the cover nut 4, thereby facilitating the attachment work of the connection object. It can be carried out. Further, such a branch plug 1 can be realized with a simple structure. Further, since the rotating member 40 does not fall below the fixing nut 30 in a state where the branch plug 1 is placed on the mixing faucet main body 2, the attachment work of the connection object can be performed more easily. .

外装本体21の中途部の外周面には、第1横溝23が周状に形成されている。また、第1横溝23は、第1貫通孔22と連通するようにして、その一部が、外装本体21の外周面における第1貫通孔22の開口部と一致するように形成されている。回転部材40の上下中途部の内周面には、第2横溝42が周状に形成されている。また、第2横溝42は、第2貫通孔41と連通するようにして、その一部が、回転部材40の内周面における第2貫通孔41の開口部と一致するように形成されている。回転部材40に前記外装本体21を嵌装することによって、第1横溝23と第2横溝42とによって外装流路25が形成され、当該外装流路25を介して、外装本体21の第1貫通孔22と回転部材40の第2貫通孔41とが連通することとなる。そして、回転部材40を周方向に回転させても、外装流路25を介して、外装本体21の第1貫通孔22と回転部材40の第2貫通孔41が連通することとなる。このため、混合水栓60に分岐栓1を取付けた状態でも、分岐栓1の水密性を確保したまま、回転部材40を周方向に回転させて、回転部材40における第2貫通孔41の外周面への開口部の周方向の位置を変更することができる。また、このような分岐栓1を簡易構造で実現することができる。なお、分岐栓1においては、外装本体21の第1横溝23と回転部材40の第2横溝42とがいずれも形成されているが、第1横溝23と第2横溝42とのうち少なくともいずれか一方が形成されることによって外装流路25が形成される構成でもよいものとする。   A first lateral groove 23 is formed in a circumferential shape on the outer peripheral surface of the middle part of the exterior body 21. Further, the first lateral groove 23 is formed so as to communicate with the first through hole 22, and a part thereof coincides with the opening of the first through hole 22 on the outer peripheral surface of the exterior body 21. A second lateral groove 42 is formed in a circumferential shape on the inner peripheral surface of the upper and lower halfway part of the rotating member 40. Further, the second lateral groove 42 is formed so as to communicate with the second through hole 41 so that a part thereof coincides with the opening of the second through hole 41 on the inner peripheral surface of the rotating member 40. . By fitting the exterior body 21 on the rotating member 40, the exterior channel 25 is formed by the first lateral groove 23 and the second lateral groove 42, and the first penetration of the exterior body 21 is performed via the exterior channel 25. The hole 22 and the second through hole 41 of the rotating member 40 communicate with each other. Even when the rotating member 40 is rotated in the circumferential direction, the first through hole 22 of the exterior body 21 and the second through hole 41 of the rotating member 40 are communicated with each other via the exterior flow path 25. For this reason, even when the branch plug 1 is attached to the mixing tap 60, the rotation member 40 is rotated in the circumferential direction while ensuring the watertightness of the branch plug 1, and the outer periphery of the second through hole 41 in the rotation member 40. The circumferential position of the opening to the surface can be changed. Moreover, such a branch plug 1 can be realized with a simple structure. In the branch plug 1, both the first lateral groove 23 of the exterior body 21 and the second lateral groove 42 of the rotating member 40 are formed, but at least one of the first lateral groove 23 and the second lateral groove 42 is formed. A configuration in which the exterior channel 25 is formed by forming one of them may be used.

また、分岐栓1の外装部材20は、別体である外装本体21と固定ナット30とから構成されているが、外装本体21と固定ナット30とを一体として構成してもよいものとする。このように、外装部材20を構成しても、混合水栓60に分岐栓1を取付けた状態で、回転部材40を周方向に回転させて、回転部材40の第2貫通孔41における外周面への開口部の周方向の位置を変更することができる。したがって、外装部材20の螺合を緩めることなく、第2貫通孔41に接合された接続部材50の周方向の位置を変更することができ、接続対象物の取付け作業を容易に行うことができる。また、外装本体21を混合水栓本体2に固定する方法は、固定ナット30を混合水栓本体2に螺合させることによって固定する方法に特に限定するものではない。   Moreover, although the exterior member 20 of the branch plug 1 is composed of the exterior body 21 and the fixing nut 30 which are separate bodies, the exterior body 21 and the fixing nut 30 may be integrally configured. In this way, even if the exterior member 20 is configured, the outer peripheral surface of the second through hole 41 of the rotating member 40 is rotated by rotating the rotating member 40 in the circumferential direction with the branch plug 1 attached to the mixing faucet 60. The position of the opening in the circumferential direction can be changed. Therefore, the position in the circumferential direction of the connection member 50 joined to the second through hole 41 can be changed without loosening the screwing of the exterior member 20, and the attachment work of the connection object can be easily performed. . The method of fixing the exterior body 21 to the mixing faucet body 2 is not particularly limited to the method of fixing by fixing the fixing nut 30 to the mixing faucet body 2.

分岐栓1においては、分岐栓本体10の水側流路12と、接続部材50の接続流路51とが、連通する構成となっているが、分岐栓本体10に形成される横孔14を湯側流路11に連通させて、分岐栓本体10の湯側流路11と、接続部材50の接続流路51とが、当該横孔14、分岐横溝15、第1貫通孔22、外装流路25、および、第2貫通孔41、を介して、連通する構成としてもよいものとする。また、分岐栓本体10に形成される横孔14を混合流路13に連通させて、分岐栓本体10の混合流路13と、接続部材50の接続流路51とを連通させる構成としてもよいものとする。   In the branch plug 1, the water-side flow path 12 of the branch plug main body 10 and the connection flow path 51 of the connection member 50 are configured to communicate with each other. The hot water side flow path 11 of the branch plug main body 10 and the connection flow path 51 of the connecting member 50 communicate with the hot water side flow path 11, and the horizontal hole 14, the branch horizontal groove 15, the first through hole 22, the exterior flow It is good also as a structure which communicates via the path | route 25 and the 2nd through-hole 41. FIG. Alternatively, the lateral hole 14 formed in the branch plug body 10 may be communicated with the mixing channel 13 so that the mixing channel 13 of the branch plug body 10 and the connection channel 51 of the connection member 50 are communicated. Shall.

接続部材50と回転部材40との接合は、接続部材50に形成された雄ネジと、回転部材40における第2貫通孔41に形成された雌ネジとを螺合させることによって行うことに特に限定するものではない。つまり、例えば接続部材50と第2貫通孔41との接合は、接続部材50の挿入部52と第2貫通孔41との間に接着剤等のシール材を介在させた状態で、当該挿入部52を第2貫通孔41に圧入するなど挿入して、挿入部52と第2貫通孔41とを接合させてもよいものとする。また、上述したようにネジの螺合によってのみ、接続部材50と第2貫通孔41とを接合してもよいものとする。   The joining of the connecting member 50 and the rotating member 40 is particularly limited to be performed by screwing a male screw formed in the connecting member 50 and a female screw formed in the second through hole 41 in the rotating member 40. Not what you want. That is, for example, the connection member 50 and the second through hole 41 are joined in a state where a sealing material such as an adhesive is interposed between the insertion portion 52 of the connection member 50 and the second through hole 41. The insertion part 52 and the second through hole 41 may be joined by inserting 52 into the second through hole 41 or the like. Further, as described above, the connection member 50 and the second through-hole 41 may be joined only by screwing screws.
