【発明の属する技術分野】
本発明は、ロータンク上部に蓋装される手洗鉢に関する。
【０００２】
【従来の技術】
従来、ロータンク上部に蓋装される手洗鉢は吐水口に接続された給水部材が立壁の裏面に沿って下方に延設されており、かつ裏面には給水部材の位置決め用の凸部がもうけられ、位置決めされる。このため、手洗鉢をロータンクに蓋装する場合、ロータンク側より手洗鉢に給水するための立上管を容易に前記給水部材に勘合させることができるので容易に着脱することができ、保守時間を大幅に短縮できた。
【０００３】
【発明が解決しようとする課題】
従来、ロータンク上部に蓋装される手洗鉢は吐水口に接続された給水部材が立壁の裏面に沿って下方に延設されており、かつ立壁裏面には給水部材の位置決め用の凸部が２ヶ所設けられ、この間に給水部材が位置決めされる。よって、手洗鉢をロータンクに蓋装する場合、ロータンク側より手洗鉢に給水するための立上管を容易に前記給水部材に勘合させることができるので容易に着脱することができ、保守時間を大幅に短縮できた。しかし、前記突起による位置決めを行なうには給水管の管径と同じ幅にあわせて突起を配置しなければ、正確な位置決めは不可能であり、吐水口を固定するための形状を給水管の先端に設けると先端がこの突起間の幅よりも大きくなり、手洗鉢背面の壁面に開口を設けるか、壁面を別部材にする必要があった。
また、吐水口を取付ける際には開口を下に向けて取付けやすいように壁面を別部材にする必要があった。
本発明は上記課題を解決するためになされたもので、吐水口が手洗鉢開口部より突出した給水部材に取付けられ、ロータンクの上部に蓋装される手洗鉢において、組み付け作業が容易なロータンクの手洗鉢を提供することにある。
【０００７】
【課題を解決するための手段】
上記課題を解決するため、本発明のロータンクの手洗鉢は、手洗鉢の開口部の裏面より挿入して前方に突出させた給水部材に吐水口を取付けたロータンクの手洗鉢において、前記吐水口にネジ固定部を設けるとともに前記給水部材にネジ孔を設け、前記手洗鉢の前面側からネジにより前記ネジ固定部を介して前記ネジ孔に固定することにより、前記吐水孔を給水部材に固定したことを特徴とする。このような構成とすることにより、吐水口を回転させることなく、手洗鉢前面側から取付けることができ、組み付け作業が容易となる。
【０００８】
また、請求項１記載のロータンクの手洗鉢において、前記給水部材に前記吐水口の位置決めを行なう凹または凸形状を設け、前記吐水口に凸又は凹形状を設けることができる。このような構成とすることにより、手洗鉢背面の立ち壁を別部材にすることなく、容易に吐水口を手洗鉢に組み立てることができる。
【０００９】
さらに、請求項１又は２記載のロータンクの手洗鉢において、前記ネジを整流板で隠蔽すれば、美観を損ねることが無い。
【００１０】
