【０００５】
【発明の実施の形態】
以下にこの発明の実施の形態について説明する。なお、この発明はそれによって限定されるものではない。
【０００６】
図１〜図６は、ポップアップ機構を備えたこの発明の一実施形態を示す。
【０００７】
図１〜図６において、ポップアップ機構を備えた湯水混合水栓１は、給湯配管（図示せず）に連通し、給湯配管とで給湯流路ｉ_１を形成する湯側取付足２と、給水配管（図示せず）に連通し、給水配管とで給水流路ｊ_１を形成する水側取付足３と、例えば流し台や洗面台の水栓取付面部上に設置される台座５と、この台座５の中央部に形成された取付用開口部５ｄを介して台座５の中央部上面にねじ接続により立設される胴１１を有する水栓本体６と、金属製の吐水管７と、ポップアップ棒８とから主としてなる。
【０００８】
そして、湯側取付足２および水側取付足３は符号は異なるが同一形状であり、両者２，３共、台座５にねじ接続により取り付けられる。すなわち、湯側取付足２は、給湯配管に接続される縦長の小径足部４０ａと台座接続用の外ねじｔが形成された大径足部４０ｂを有し、更に、大径足部４０ｂは、シール用のＯリング４０ｃを外周に有する。また、水側取付足３も、給水配管に接続される縦長の小径足部４０ａと台座接続用の外ねじｔが形成された大径足部４０ｂを有し、更に、大径足部４０ｂは、シール用のＯリング４０ｃを外周に有する。そして、一つの湯側取付足２と一つの水側取付足３とで組をなす。
【０００９】
更に、前記台座５は、前記湯側取付足２が着脱可能に接続される二つの湯側接続開口部３０および３０をそれぞれ穴部分９ａおよび９ｂに連通する形で底面５ａに有するとともに、前記水側取付足３が着脱可能に接続される水側接続開口部３１および３１をそれぞれ穴部分１０ａおよび１０ｂに連通する形で底面５ａに有する。湯側接続開口部３０と水側接続開口部３１は同一形状であり、湯側接続開口部３０は、前記外ねじｔが螺合する内ねじＴを有するとともに、水側接続開口部３１も、前記外ねじｔが螺合する内ねじＴを有する。両者３０，３１は、それぞれ底面５ａに向く形で開口している。
【００１０】
４２は、湯側接続開口部３０および水側接続開口部３１を閉塞するメクラ栓として機能する有底筒状のキャップで、湯側接続開口部３０および水側接続開口部３１にそれぞれねじ接続される。すなわち、キャップ４２は、湯側接続開口部３０および水側接続開口部３１の前記内ねじＴに螺合する外ねじｔを有する。また、キャップ４２は、湯側接続開口部３０および水側接続開口部３１にそれぞれ接続したときに、キャップ底面４２ａが台座５の底面５ａと面一になるよう形成されている。
【００１１】
前記水栓本体６の前記胴１１は金属製である。この胴１１は、楕円体の長軸方向における両端を切り取ってなる外観形状を有し、止水・吐水機能、湯・水を混合する機能および流量を調節する機能を有する弁を備えた弁ユニット（図示せず）を収容する収容部分１１ａと、水または湯水混合水の導出口部１２と、湯受け入れ流路ｉ_２に連通する湯導入流路ｉ_３、水受け入れ流路ｊ_２に連通する水導入流路ｊ_３および弁ユニット内で混合された湯水混合水または弁ユニット内を通った水の前記導出口部１２への流路を形成する導出穴１３とを有するとともに、ポップアップ棒８が挿通可能な挿通穴（図示せず）を背面および底面間を貫通させた状態で有する。そして、前記胴１１および弁ユニットとから水栓本体６が構成される。更に、胴１１は、湯受け入れ流路ｉ_２と湯導入流路ｉ_３とを連通させる連通流路ｉ’を形成するアダプタ７０と、水受け入れ流路ｊ_２と水導入流路ｊ_３を連通させる連通流路ｊ’を形成するアダプタ７１とをそれぞれアダプタ収容用開口部６７，６８に有する。
【００１２】
１４は、前記弁に連動連結された操作部材である。この操作部材１４の操作によって止水・吐水状態の切替操作と湯・水混合水の温度調整と流量調節が行われる。また、吐水管７は、外径Ｈの例えば銅製の棒体を鍛造で加工成形してなる。
【００１３】
前記吐水管７は、前記導出口部１２に連通する連通穴１５を有する筒状の継手部材１６を介して胴１１に着脱自在に接続してある。更に、前記吐水管７は、先端に吐水口部７ａを有する一方、後端に継手部材１６の下流端部がシール可能に差し込まれるための差し込み穴部１７を有する。
【００１４】
また、継手部材１６は、前記導出口部１２にねじ結合される。すなわち、継手部材１６は、外ねじｘが形成された上流端部を有し、一方、導出口部７は、前記外ねじｘに螺合する内ねじｙが形成されたねじ部を有する。
【００１５】
また、吐水管７には、吐水管回り止め用のピン１８の一方端が嵌め込まれるピン孔１９が差し込み穴部１７の下部の端面側から穿設されている。一方、導出口部１２の側にも前記ピン１８の他方端が嵌め込まれるピン孔２０が穿設されている。更に、吐水管７には、吐水管７が継手部材１６から抜けるのを防止する吐水管抜け止め用のねじ２１が螺合するねじ孔２２が、差し込み穴部１７の底部側から穿設されている。
【００１６】
前記台座５は、金属の素材を所定形状に鍛造したものに湯受け入れ流路形成用の穴（貫通穴）９および水受け入れ流路形成用の穴（貫通穴）１０を鍛造成形してなる。前記穴９，１０は、同形で、吐水量をかせぐのに充分な大きさの径ｂを有し、前記穴９は、給湯流路ｉ_１に連通する湯受け入れ流路ｉ_２を形成する。また、前記穴１０は、給水流路ｊ_１に連通する水受け入れ流路ｊ_２を形成する。
【００１７】
前記台座５は、薄型で、平面視および底面視楕円形状をなし、前記取付用開口部５ｄと平坦な底面５ａとなだらかな山型形状の上面５ｂを有し、中央部に上下を貫く複数のねじ挿通孔２５を有する。このねじ挿通孔２５は、台座５の上面５ｂの中央部に配置される胴１１の底部に設けたねじ孔（図示せず）に整合され、台座５の底面５ａ側からねじ挿通孔２５を介して挿通されたねじを前記ねじ孔に螺合させることにより台座５の中央部上面に胴１１を設置することができる。また、前記台座５は、取付用開口部５ｄの中央に、水栓本体６の背面および底面間を貫通させた挿通穴（図示せず）を通ったポップアップ棒８が挿通可能な挿通穴１００を有する。
【００１８】
そして、前記穴９は、台座５の底面５ａの側の隣接する領域Ａ，Ｂの二箇所から鍛造用のパンチをそれぞれ駆動させることによって穿設される。つまり、底面５ａの領域Ａの側から斜め右上方に縦断面円形の径ｂを有する直線状の穴部分９ａが鍛造成形され、この穴部分９ａに連通するよう、底面５ａの領域Ｂの側から斜め左上方に縦断面円形の径ｂを有する直線状の穴部分９ｂが鍛造成形され、領域Ａ側および領域Ｂ側を貫通する穴９が鍛造成形される。穴部分９ｂは、前記取付用開口部５ｄに連通している。同様に、前記穴１０は、底面５ａの側の隣接する領域Ｃ，Ｄの二箇所から鍛造用のパンチをそれぞれ駆動させることによって穿設され、縦断面円形の径ｂを有する直線状の穴部分１０ａ，１０ｂよりなり、領域Ｃ側および領域Ｄ側を貫通する穴１０が鍛造成形される。穴部分１０ａは、前記取付用開口部５ｄに連通している。このように前記穴９および穴１０を、図７に示すようにそれぞれ一箇所ＡおよびＤからだけではなく、それぞれ二箇所の領域Ａ，ＢおよびＣ，Ｄから鍛造成形したのは、以下の理由による。
【００１９】
図７は、底面５ａの側の領域Ａからだけ鍛造用のパンチを駆動させることによって小径ａの穴９’を形成するとともに、底面５ａの側の領域Ｄからだけ鍛造用のパンチを駆動させることによって小径ａの穴１０’を形成するようにした比較例を示している。図７において、鍛造用のパンチ一つで小径穴９’は形成され、また、鍛造用のパンチ一つで小径穴１０’は形成されるが、小径ａなので吐水量は小さい。しかし、例えば水側の場合、吐水量をかせぐために、穴１０’より大径ｂ（＞ａ）の二点鎖線で示すような穴１０’’を領域Ｄから鍛造用のパンチ一つを駆動させることによって形成しようとしても、穴１０’’によって形成される水受け入れ流路ｊ_２’を水導入流路ｊ_３に連通させることは難しいことが、図７から分かる。同様に、吐水量をかせぐために、穴９’より大径ｂ（＞ａ）の穴を領域Ａから鍛造用のパンチ一つを駆動させることによって形成するのは難しい。これに対し、この発明では、二つの鍛造用のパンチを二箇所の領域Ａ，ＢおよびＣ，Ｄから駆動させてそれぞれ大径ｂの穴９および穴１０を形成しているので、穴９によって形成される湯受け入れ流路ｉ_２を前記取付用開口部５ｄに設置された胴１１の連通流路ｉ’を介して湯導入流路ｉ_３に連通させることができるとともに、穴１０によって形成される水受け入れ流路ｊ_２を前記取付用開口部５ｄに設置された胴１１の連通流路ｊ’を介して水導入流路ｊ_３に連通させることができる。
【００２０】
そして、金属の素材を前記取付用開口部５ｄと平坦な底面５ａとなだらかな山型形状の上面５ｂを有し平面視および底面視楕円形状に鍛造したものに、前記台座５の底面５ａの隣接する二つの領域ＡおよびＢから湯受け入れ流路形成用の穴９を鍛造成形するとともに、前記台座５の底面５ａの隣接する二つの領域ＣおよびＤから水受け入れ流路形成用の穴１０を鍛造成形し、その後、二つの湯側接続開口部３０，３０用の溝部を穴部分９ａおよび９ｂの底面入口側に成形するとともに、前記溝部と同一形状の、二つの水側接続開口部３１，３１用の溝部を穴部分１０ａおよび１０ｂの底面入口側に成形し、更に、これら四つの溝部に、大径足部４０ｂに形成した前記外ねじｔおよびキャップ４２に形成した前記外ねじｔに螺合する内ねじＴを設けることにより、二つの湯側接続開口部３０，３０と二つの水側接続開口部３１，３１を形成することができる。
【００２１】
而して、湯水混合水栓１を流し台の水栓取付面部上に設置するときは、両取付足２，３間の間隔Ｅが洗面台の場合より長いので、領域Ａの湯側接続開口部３０に取付足２を接続するとともに、領域Ｄの水側接続開口部３１に取付足３を接続する。更に、キャップ４２を、領域Ｂの湯側接続開口部３０に接続するとともに、キャップ４２を、領域Ｃの水側接続開口部３１に接続する。
【００２２】
一方、湯水混合水栓１を洗面台の水栓取付面部上に設置するときは、両取付足２，３間の間隔Ｅが流し台の場合より長いので、領域Ｂの湯側接続開口部３０に取付足２を接続するとともに、領域Ｃの水側接続開口部３１に取付足３を接続する。更に、キャップ４２を、領域Ａの湯側接続開口部３０に接続するとともに、キャップ４２を、領域Ｄの水側接続開口部３１に接続する。
【００２３】
また、図２に示すように、間隔Ｅで両取付足２，３が取り付けられている台座５から、領域Ｄの水側取付足３を取り外すとともに、水側取付足３に隣接して配置されていた領域Ｃのキャップ４２も取り外し、このキャップ４２を、水側接続開口部３１が取り付けられていた領域Ｄの水側接続開口部３１に接続し、また、キャップ４２が取り付けられていた領域Ｃの水側接続開口部３１に水側取付足３を接続するといたように、両取付足２，３間の間隔Ｅを自由に可変できて、両取付足２，３の台座５への取り付けの自由度を拡げることができる。この実施形態では湯側接続開口部３０と水側接続開口部３１を二組設けているので、両取付足２，３の取り付け状態を四種類に設定できる。
【００２４】
また、台座５を、金属の素材を鍛造して、薄型で、平面視および底面視楕円形状で、前記取付用開口部５ｄと平坦な底面５ａとなだらかな山型形状の上面５ｂを有する形状とすることにより、従来のステンレス製の台座８０に比して、重量感が増するとともに、水栓本体６の胴１１を、楕円体の長軸方向における両端を切り取ってなる外観形状とし、かつ、胴１１を、台座５の中央に設けた取付用開口部５ｄに取付けたので、図１に示す胴１１と台座５の境界部分をシャープな形状にでき、見栄えがする。
【００２５】
なお、この実施形態では湯側接続開口部３０と水側接続開口部３１を二組設けたものを示したが、三組以上設けた場合にもこの発明は適用できる。
【００２６】
【発明の効果】

FIG. 7 shows that the hole 9 ′ having a small diameter a is formed by driving the forging punch only from the region A on the bottom surface 5 a side, and the forging punch is driven only from the region D on the bottom surface 5 a side. This shows a comparative example in which a hole 10 'having a small diameter a is formed. In FIG. 7, a small-diameter hole 9 'is formed with a single forging punch, and a small-diameter hole 10' is formed with a single forging punch. However, in the case of the water side, for example, in order to increase the amount of water discharged, a hole 10 ″ having a larger diameter b (> a) than the hole 10 ′ is driven from the region D by one forging punch. It can be seen from FIG. 7 that it is difficult to make the water receiving flow path j ₂ ′ formed by the hole 10 ″ communicate with the water introduction flow path j ₃ even if it is attempted to do so. Similarly, it is difficult to form a hole having a larger diameter b (> a) than the hole 9 ′ by driving one forging punch from the area A in order to increase the amount of water discharged. On the other hand, in the present invention, the two forging punches are driven from the two regions A, B and C, D to form the large-diameter b holes 9 and 10, respectively. with hot water receiving channel i ₂ which is formed can be in communication with the hot water introduction channel i ₃ through the communication passage i 'of the body 11 installed in the mounting opening 5d, formed by the holes 10 water recipient passages j ₂ via the communication passage j of the body 11 installed in the mounting opening 5d 'can be in communication with the water inlet flow path j ₃ that.
