The interior space of the mounting portion 2, that is, the drain passage 15, is communicated and opened to the outside of the handle main body 4, that is, the faucet lever handle 1 through the opening.

本発明のもう一つの特徴的な構成は、前記排水流路１５が傾斜している点である。
即ち、装着部２の底壁２Ｂは、図２に示すように、前記部分円弧部分２Ａ側からハンドル本体４の前記レバー部分３の存在側とは反対側の周縁４Ａ、即ち基端部に向かうほどより低位にあるように傾斜面に構成されている。この傾斜面は、水栓用レバーハンドル１が、その吐・止水のための上下操作の下限限界姿勢にあっても、常にハンドル本体４の基端部の前記排水２０側が下位にあるように構成されている。即ち前記レバー部分３の存在側とは反対側で前記キャップ５の前記排水口２０を設けてある側が、ハンドル本体４のどのような作用姿勢にあっても、常に下位にあるように傾斜するように構成されているのである。 Another characteristic configuration of the present invention is that the drain passage 15 is inclined.
That is, as shown in FIG. 2, the bottom wall 2 </ b> B of the mounting portion 2 is directed from the partial arc portion 2 </ b> A side to the peripheral edge 4 </ b> A of the handle main body 4 on the opposite side to the side where the lever portion 3 exists, that is, the base end portion. The inclined surface is configured so as to be lower. Even if the faucet lever handle 1 is in the lower limit position of the vertical operation for discharging and stopping the water, the inclined surface is so arranged that the drain 20 side of the base end of the handle body 4 is always lower. It is configured. That is, the side of the cap 5 on which the drain port 20 is provided on the side opposite to the side on which the lever portion 3 is present is inclined so that it is always at a lower position regardless of the operating posture of the handle body 4. It is configured as

このように構成された本発明に係る水栓用レバーハンドル１の水浸入防止構造によれば、前記キャップ５の周縁と装着部２の上縁の隙間から装着部２内に浸入してくる水滴や洗剤は装着部２の内周壁２Ｃを伝って底壁２Ｂに至る。従来構造であれば前記係止孔７やネジ孔８から弁装置１０側へ更に浸入しようとするが、本発明ではこれら係止孔７並びにネジ孔８の周囲は液体浸入阻止用の隔壁１２で囲繞されているので、これら係止孔７並びにネジ孔８内への水滴や洗剤の浸入が確実に阻止される。しかも、装着部２の底壁２Ｂの傾斜は、水栓用レバーハンドル１が、その吐・止水のための上下操作の下限限界姿勢にあっても、ハンドル本体４の前記排水口２０側、即ち前記キャップ５の切欠き存在側が常に下位にあるように構成されているために、浸入した水滴や洗剤は，水栓用レバーハンドル１が如何なる姿勢にあっても、この傾斜によって素早く、また的確に前記排水口２０へと誘引されることになる。そして、この遮蔽壁１９に至った水滴や洗剤は遮蔽壁１９の内面に沿ってその中央側へと案内され、最終的にはこの遮蔽壁１９に設けられた前記排水口２０から水栓用レバーハンドル１の外へと効率良く排出される。   According to the water intrusion prevention structure of the faucet lever handle 1 according to the present invention configured as described above, water droplets penetrating into the mounting portion 2 from the gap between the peripheral edge of the cap 5 and the upper edge of the mounting portion 2. The detergent flows along the inner peripheral wall 2C of the mounting portion 2 and reaches the bottom wall 2B. In the case of the conventional structure, it is attempted to further penetrate into the valve device 10 through the locking hole 7 and the screw hole 8. However, in the present invention, the periphery of the locking hole 7 and the screw hole 8 is a partition 12 for preventing liquid from entering. Since it is surrounded, the intrusion of water droplets and detergent into the locking holes 7 and the screw holes 8 is reliably prevented. Moreover, the inclination of the bottom wall 2B of the mounting portion 2 is such that even if the faucet lever handle 1 is in the lower limit position of the vertical operation for discharging and stopping water, the drain port 20 side of the handle body 4 That is, since the notch-existing side of the cap 5 is always located at a lower position, water droplets and detergent that have entered can be quickly and accurately owing to the inclination regardless of the posture of the lever handle 1 for faucet. Is drawn to the drain port 20. Water droplets and detergent reaching the shielding wall 19 are guided to the center side along the inner surface of the shielding wall 19, and finally, a faucet lever is provided from the drain port 20 provided on the shielding wall 19. It is efficiently discharged out of the handle 1.

このように、弁装置１０側への水滴や洗剤の浸入を的確に、また効率良く、しかも確実に阻止し、併せて効率よく、しかも的確にハンドル本体４から外部へ排出することができるので、常に軽快な弁操作が可能で、しかも、弁装置の劣化や破壊を的確に防止することができる。   In this way, the ingress of water droplets and detergent into the valve device 10 can be accurately, efficiently, and reliably prevented, and at the same time, can be efficiently and accurately discharged from the handle body 4 to the outside. Light valve operation is always possible, and furthermore, deterioration and destruction of the valve device can be accurately prevented.

次に、上記の水栓用レバーハンドルの水浸入防止構造の変形例を、図６〜８の記載に基づいて詳述する。
上記図１〜５に示した実施例では、前記キャップ５に設けた前記排水口２０としての切欠きが、前記遮蔽壁１９の左右方向の中央部分に設けられた例を示したが、本実施例では、前記遮蔽壁１９の左右に夫々切欠きが設けられている。 Next, a modified example of the water intrusion prevention structure of the faucet lever handle will be described in detail with reference to FIGS.
In the embodiment shown in FIGS. 1 to 5 described above, the notch as the drain port 20 provided in the cap 5 is provided in the center part of the shielding wall 19 in the left-right direction. In the example, cutouts are provided on the left and right sides of the shielding wall 19, respectively.

前記排水流路１５は装着部２の相似形をした前記隔壁１２で囲繞されることから、排水流路１５は左右一対存在することになる。上記図１〜５に示した実施例の構造では、前記遮蔽壁１９に至った水滴や洗剤は、一度この遮蔽壁１９の中央部へと案内され、中央の一か所の前記排水口２０から外部へ排出される。従って、浸入量が多い場所等では、一部の水滴や洗剤が、前記係止孔７の間に存在する底壁２Ｂ部分に一時的に留まる傾向がみられる。しかし、この変形例によれば、左右の排水流路１５の流下終端に前記排水口２０が夫々開口存在しているので、排水流路１５を流下する水滴や洗剤はその流れを阻害されることなく、スレートに、スムーズに水栓用レバーハンドル１の外へ排出され、一層効率の良い排出が可能となる。   Since the drainage channel 15 is surrounded by the partition wall 12 having a similar shape to the mounting portion 2, the drainage channel 15 has a pair of left and right sides. In the structure of the embodiment shown in FIGS. 1 to 5, the water droplets and the detergent that have reached the shielding wall 19 are once guided to the central portion of the shielding wall 19, and from the drainage port 20 at one central position. It is discharged outside. Therefore, in places where the amount of intrusion is large, there is a tendency that some water droplets and detergent tend to temporarily stay on the bottom wall 2B existing between the locking holes 7. However, according to this modification, since the drain outlets 20 are respectively provided at the downstream ends of the left and right drain passages 15, the water droplets and the detergent flowing down the drain passage 15 are obstructed from flowing. In addition, the water is smoothly discharged out of the faucet lever handle 1 in a slate, and more efficient discharge is possible.

前記排水口２０は、図１〜５に示す例では中央１か所、また、図６〜８に示す例では左右２か所に設けた例を示したが、必要に応じて中央１か所と左右２か所の都合３か所に設けるようにしても良い。一層効率の良く、また、一層スムーズに水滴や洗剤を水栓用レバーハンドル１の外へ排出できるからである。また、変形例として、図示しないが、係止孔７とネジ孔８とが夫々独立別個に隔壁１２で囲繞されるようにした構成も採用できる。   In the example shown in FIGS. 1 to 5, the drain port 20 is provided at one center, and in the example shown in FIGS. And two places on the left and right for convenience. This is because water droplets and detergent can be discharged to the outside of the faucet lever handle 1 more efficiently and more smoothly. Further, as a modified example, although not shown, a configuration in which the locking hole 7 and the screw hole 8 are individually and separately surrounded by the partition wall 12 can be adopted.

以上説明した各実施例は、必ずしも図示する構造に限定されるものではなく、示された個々の構造、形状は発明の趣旨と矛盾しない範囲で相互に組み合わせたり、援用したりすることができる。また、本発明における水栓用ハンドルの排水構造は、以上のシングルレバー式の湯水混合栓の水栓用レバーハンドルの他、例えば弁装置の操作軸が仮想鉛直線に沿って配される回転式の水栓用ハンドル等にも適用される。   The embodiments described above are not necessarily limited to the illustrated structure, and the individual structures and shapes shown can be combined with each other or incorporated without departing from the spirit of the invention. Further, the drainage structure of the faucet handle of the present invention is, in addition to the faucet lever handle of the single-lever hot water mixer tap described above, for example, a rotary type in which the operation axis of the valve device is arranged along a virtual vertical line. It is also applied to the faucet handle etc.
