JP-A-9-125506 (page 1-3, FIG. 1)

しかしながら、上記特許文献１の第１図から明らかなように、該特許文献においては、給水配管と衛生陶器（洋風便器）の給水口とは多数の部品を組み合わせて接続され、また、その接続構造も複雑なものとなっている。本発明は上記問題を解決し、給水配管と水洗便器の給水口とを少ない部品点数で、作業性よく接続できるとともに、水密性に優れた洗浄水給水配管の接続構造を提供することを、その課題とする。 However, as is apparent from FIG. 1 of the above-mentioned Patent Document 1, in this Patent Document, the water supply pipe and the water supply port of the sanitary ware (Western toilet) are connected in combination with each other, and the connection structure thereof Is also complicated. The present invention solves the above problems and provides a connection structure for a wash water / water supply pipe that has good workability and can connect the water supply pipe and the water supply port of the flush toilet with a small number of parts. Let it be an issue.

上記した課題を解決するために、本発明においては、つぎのような技術的手段を講じている。すなわち、本発明によれば、水洗便器の給水口へ洗浄水の給水配管を接続する構造であって、該接続構造は上記給水口へ嵌着され、かつ、筒状の弾性材料からなる凹形継手と先端部が該凹形継手に挿入される凸形継手とからなり、上記凹形継手には内径が徐々に減少するテーパ形状のソケット部が内設されるとともに、上記凸形継手の先端部近傍には上記ソケット部に弾性係止する鍔状係止部が周設された洗浄水給水配管の接続構造が提供される。上記凸形継手の材質は金属、プラスチックス等、硬質材料であればとくに限定されるものではないが、硬質プラスチックスが好ましく用いられる。 In order to solve the above-described problems, the present invention takes the following technical means. That is, according to the present invention, it is a structure for connecting a water supply pipe for cleaning water to a water supply opening of a flush toilet, the connection structure being fitted to the water supply opening and having a concave shape made of a cylindrical elastic material. The joint is composed of a joint and a convex joint inserted into the concave joint, and the concave joint is provided with a tapered socket portion whose inner diameter gradually decreases, and the tip of the convex joint. In the vicinity of the portion, there is provided a connection structure for the cleaning water supply pipe in which a hook-like locking portion that elastically locks to the socket portion is provided. The material of the convex joint is not particularly limited as long as it is a hard material such as metal or plastics, but hard plastics are preferably used.

上記凹形継手の両端部にはフランジ部が備えられることが好ましい。また、上記鍔状係止部の円周端には抜け止め用の係止爪が周設されることが好ましい。さらに、上記凹形継手を形成する筒状の弾性材料としてはとくに限定されず、プラスッチクス、ゴム等が用いられるが、ゴムとくに、合成ゴムが好ましく用いられる。 It is preferable that flange portions are provided at both ends of the concave joint. Further, it is preferable that a locking claw for retaining the cover is provided around the circumferential end of the hook-shaped locking portion. Further, the cylindrical elastic material forming the concave joint is not particularly limited, and plastics, rubber, and the like are used, but rubber, particularly, synthetic rubber is preferably used.

請求項１に記載の発明は上記のとおりであり、凸形継手とともに洗浄水給水配管の接続構造を構成する凹形継手は、内径が徐々に減少するテーパ形状のソケット部が内設され、凸形継手の先端部近傍には上記ソケット部に弾性係止する鍔状係止部が周設されているため、凸形継手の先端部を上記弾性材料から形成されたソケット部に単に挿入し、鍔状係止部によりしっかりと係止させるのみで、狭い空間でスパナやレンチ等の工具を使用することなく、簡単に、水密性よく給水配管を水洗便器の給水口へ接続することができる。 The invention according to claim 1 is as described above, and the concave joint that constitutes the connection structure of the cleaning water supply pipe together with the convex joint has a tapered socket portion in which the inner diameter gradually decreases, Since a hook-like locking part that elastically locks to the socket part is provided in the vicinity of the tip part of the shape joint, the tip part of the convex joint is simply inserted into the socket part formed of the elastic material, The water supply pipe can be easily connected to the water supply port of the flush toilet without using a tool such as a wrench or a wrench in a narrow space simply by being firmly locked by the hook-shaped locking portion.

上記凹形継手の両端部にはフランジ部が設けられているため、給水口に嵌着された凹形継手はフランジ部が給水口を形成する周囲部に掛かってしっかりと弾性係止される。また、上記鍔状係止部の円周端には抜け止め用の係止爪が周設されているため、凸形継手の先端部をソケット部に挿入したとき、上記係止爪がソケット部内の弾性材料に埋め込まれ、食い込んでしっかりと抜け止め効果を発揮する。 Since flange portions are provided at both ends of the concave joint, the concave joint fitted to the water supply port is firmly elastically locked by the flange portion hanging around the peripheral portion forming the water supply port. In addition, since a locking claw for retaining is provided around the circumferential end of the hook-shaped locking portion, when the tip of the convex joint is inserted into the socket portion, the locking claw is not inside the socket portion. It is embedded in the elastic material, and it bites in and exhibits a secure retaining effect.

上記凹形継手を形成する筒状の弾性材料がゴムであるため、凸形継手の先端部は凹形継手に内設されたソケット部の内面を弾性的に押し広げて進入するとともに、給水配管と給水口との多少の芯ズレは弾性的に吸収され、作業性よく接続することができる。 Since the cylindrical elastic material forming the concave joint is rubber, the tip of the convex joint elastically pushes the inner surface of the socket part provided in the concave joint and enters the water supply pipe. Some misalignment between the water inlet and the water inlet is elastically absorbed and can be connected with good workability.

以下、本発明の実施形態について図面を参照して、詳細に説明する。図１は、本発明にかかる洗浄水給水配管の接続構造を構成する凹形継手１と凸形継手２とを示す斜視図である。図１において、弾性材料としての合成ゴムからなり、本体が筒状とされた凹形継手１には、内径が徐々に減少するテーパ形状のソケット部１２が内設され、両端部にはフランジ部１１が設けられている。一方、硬質プラスッチクスからなる凸形継手２は、図１の矢印の方向にしたがってソケット部１２に挿入されるとともに、その先端部２１近傍には、鍔状の係止部２２が周設されている。また、この鍔状係止部２２の円周端には抜け止め用の係止爪２２１が設けられている。さらに、凸形継手２の後端部２３は給水配管３に接続され、図示しない給水操作弁を操作することにより洗浄水が水洗便器内に吐出される。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a concave joint 1 and a convex joint 2 constituting a connection structure for a cleaning water supply pipe according to the present invention.
