実開平５−７１２６５号公報Japanese Utility Model Publication No. 5-71265

上記特許文献１のものは、ホースガイドに設けた挿通孔に可撓管が移動可能に挿通されるとともに、合成樹脂製のホースガイドに設けた一対の挟持部間に給水用導入管、給湯用導入管および混合水用導出管が互いに接し合わされた状態で挟持されている。そのため、上記特許文献１のものは、水栓本体の筒状の取付足を小径にすることができて流し台等の水栓取付部に小径の貫通穴を形成すればよく、予め水栓取付部に所定の小径の貫通穴を形成しておけば、その貫通穴をハンドシャワ付きの湯水混合栓の取り付けと、ハンドシャワを備えていない通常の湯水混合栓の取り付けとに兼用することができるといったメリットを有している。   In the above-mentioned Patent Document 1, a flexible pipe is movably inserted into an insertion hole provided in a hose guide, and a water supply introduction pipe and a hot water supply are provided between a pair of holding parts provided in a synthetic resin hose guide. The introduction pipe and the mixed water outlet pipe are held in contact with each other. Therefore, the thing of the said patent document 1 can just make a small diameter through-hole in faucet attachment parts, such as a sink, so that the cylindrical attachment leg of a faucet body can be made into a small diameter, and a faucet attachment part beforehand If a through hole having a predetermined small diameter is formed in the through hole, the through hole can be used both for mounting a hot and cold water mixing tap with a hand shower and for mounting a normal hot water mixing tap without a hand shower. Has a merit.

しかし、可撓管が挿通される挿通孔は一部が開口しており、この開口を介して給水用導入管、給湯用導入管および混合水用導出管と可撓管の干渉を招くおそれがある。
また、取付足の下方開口端の内周面に形成された嵌合部にホースガイドが嵌合固定される構成になっているので、たとえきっちりと嵌め込まれていても長期の使用で可撓管の移動による擦れ等によって取付足からホースガイドが脱落するおそれがある。 However, a part of the insertion hole through which the flexible pipe is inserted is opened, and there is a possibility that the water supply introduction pipe, the hot water supply introduction pipe, the mixed water outlet pipe and the flexible pipe may interfere with each other through the opening. is there.
In addition, since the hose guide is fitted and fixed to the fitting portion formed on the inner peripheral surface of the lower opening end of the mounting foot, the flexible tube can be used for a long time even if it is fitted tightly. There is a risk that the hose guide may fall off the mounting foot due to rubbing due to movement of the foot.

この発明は、上述の事柄に留意してなされたもので、その目的は、ハンドシャワを備えていない通常の湯水混合栓の取り付けとに兼用させながら、給水用導入管、給湯用導入管および混合水用導出管と可撓管の干渉、ならびに、ホースガイドの取付足からの脱落を防止できる湯水混合栓を提供することである。   The present invention has been made in consideration of the above-mentioned matters. The purpose of the present invention is to provide a water supply introduction tube, a hot water supply introduction tube, and a mixing device while also being used for mounting a normal hot water mixing tap without a hand shower. It is an object of the present invention to provide a hot and cold water mixing plug capable of preventing interference between a water outlet pipe and a flexible pipe, and dropping of a hose guide from a mounting foot.

上記目的を達成するために、この発明の湯水混合栓は、可撓管を介してシャワヘッドを引出し可能に支持するシャワーホルダーを有する水栓本体と、水栓取付部に形成された貫通穴に挿入して固定される水栓本体の筒状の取付足と、この取付足内に嵌込まれて、水栓本体内の弁機構にそれぞれ接続される給水用導入管、給湯用導入管および混合水用導出管と、前記可撓管を挿通可能なホースガイドとを備え、前記ホースガイドは、可撓管を挿通するための挿通孔を有するとともに、前記ホースガイドが前記取付足内に嵌込まれたときに前記取付足とで前記給水用導入管、給湯用導入管および混合水用導出管が挿通可能な単一の挿通空間が形成される形状を有し、さらに、前記単一の挿通空間と前記挿通孔とを仕切る仕切部を有し、前記ホースガイドは、全体で前記挿通孔を形成し、かつ、背面部が前記仕切部を構成する筒部を内側に有するとともに、外側に、前記筒部の前面に外接する形で該筒部に一体に設けられ弾性変形可能な横断面半円弧状の嵌込部を有することを特徴としている（請求項１）。
なお、この発明におけるホースガイドは、水栓本体のシャワーホルダーからシャワヘッドと共に引き出される可撓管をガイドする機能を有するものであり、ホースガイドの“ホース”とは可撓管のことである。 In order to achieve the above object, the hot and cold water mixing plug of the present invention includes a faucet body having a shower holder that supports a shower head so that it can be pulled out through a flexible tube, and a through hole formed in the faucet mounting portion. A cylindrical mounting foot of the faucet body to be inserted and fixed, and a water supply introduction pipe, a hot water supply introduction pipe and a mixture that are fitted into the attachment leg and connected to the valve mechanism in the faucet body, respectively.

請求項１に係る発明では、給水用導入管、給湯用導入管および混合水用導出管が位置する単一の挿通空間と可撓管を挿通するための挿通孔とが仕切部で仕切られているので、給水用導入管、給湯用導入管および混合水用導出管と可撓管の干渉を確実に防止できる。
また、仕切部を設けてはいるが、この仕切部は実質的に薄く設定することができるものであり、また、給水用導入管、給湯用導入管および混合水用導出管ごとに挿通孔を設けることなく単一の挿通空間にこれらを位置させるようにしているので、ハンドシャワ付きの湯水混合栓の取り付けと、ハンドシャワを備えていない通常の湯水混合栓の取り付けとに兼用することができる。 In the invention according to claim 1, the single insertion space where the water supply introduction pipe, the hot water supply introduction pipe and the mixed water outlet pipe are located and the insertion hole for inserting the flexible pipe are partitioned by the partition portion. Therefore, it is possible to reliably prevent interference between the water supply introduction pipe, the hot water supply introduction pipe, the mixed water outlet pipe, and the flexible pipe.
In addition, although a partition is provided, the partition can be set to be substantially thin, and an insertion hole is provided for each of the water supply introduction pipe, the hot water supply introduction pipe, and the mixed water discharge pipe. Since these are positioned in a single insertion space without being provided, it can be used both for mounting a hot and cold water mixing tap with a hand shower and for mounting a normal hot and cold water mixing tap without a hand shower. .

請求項２〜３に係る発明では、ホースガイドのガタツキを確実に抑えながら、可撓管の移動による擦れ等によっても取付足からホースガイドが脱落するおそれは無くなる。
また、取付足にホースガイドを嵌込んだときに取付足から筒部の上方開口端を含むホースガイド上端部が突出するとともに、筒部の上方開口端の内周面は上向きに形成された先細り形状を有するようにしてもよく、この場合、可撓管の挿通孔への出入りの際に、この筒部の上方開口端の内周面に摺接しても、可撓管の挿通孔への出入りの操作をスムーズに行えるとともに、従来のように、可撓管の出入りにより取付足の上方開口端部に当接したりして可撓管が損傷するおそれもなくなる。 In the inventions according to claims 2 to 3, there is no possibility that the hose guide falls off from the mounting foot due to rubbing or the like due to movement of the flexible tube while reliably suppressing the rattling of the hose guide.
Further, when the hose guide is fitted into the mounting foot, the upper end portion of the hose guide including the upper opening end of the tubular portion protrudes from the mounting foot, and the inner peripheral surface of the upper opening end of the tubular portion is tapered upward. In this case, when the flexible tube enters and exits the insertion hole of the flexible tube, even if it slides on the inner peripheral surface of the upper opening end of the cylindrical portion, the flexible tube is inserted into the insertion hole. The entry / exit operation can be performed smoothly, and there is no risk of the flexible tube being damaged by coming into contact with the upper opening end of the mounting foot due to the entry / exit of the flexible tube.
