Description

本発明は、排水栓に関する。 The present invention relates to drain plugs.

湯を溜める浴槽の底部に設けられる排水栓には、排水口を塞ぐゴム栓や、プッシュ式の栓が用いられている。例えば、特許文献１には、水平回転させるための指掛け部を有する止水蓋の下方に栓体支持部材を設け、排水口に連通する排水管内に、栓体支持部材が載置される高さ調整部材を設けた排水栓が開示されている。高さ調整部材は、栓体支持部材が開栓時に載る上昇段部、閉栓時に載る下降段部、および上昇段部と下降段部を連続させる傾斜部を有する。 A rubber plug or a push-type plug is used as the drain plug provided at the bottom of the bathtub where hot water is stored. For example, in Patent Document 1, a stopper support member is provided below a water shutoff lid having a finger hook for horizontal rotation, and the height at which the stopper support member is placed in a drain pipe communicating with a drain port is disclosed. A drain plug with an adjustable member is disclosed. The height adjusting member has an ascending stepped portion on which the plug supporting member rests when the plug is opened, a descending stepped portion on which the stopper is placed when the stopper is closed, and an inclined portion connecting the ascending stepped portion and the descending stepped portion.

特許文献１に記載の排水栓では、止水蓋に人体等の荷重がかかると、上昇段部や栓体支持部材が破損する虞があり、破損した場合には排水管ごと交換する必要があった。また、高さ調整部材が排水管内に設けられているため、汚れやヌメリが高さ調整部材に付着した場合に清掃することが困難であった。 In the drain plug described in Patent Document 1, when a load such as a human body is applied to the water shut-off lid, there is a risk that the ascending stepped portion or the plug support member will be damaged, and if the drain plug is damaged, it will be necessary to replace the entire drain pipe. rice field. In addition, since the height adjusting member is provided inside the drain pipe, it is difficult to clean the height adjusting member when dirt or slime adheres to the height adjusting member.

また、高さ調整部材が排水管の内部に突出しているため、排水管の通水面積が減って排水性能が低下してしまう。排水性能の低下は、特許文献１に例示されている洗面器等のように比較的に少量の水を排水する箇所では許容されたとしても、浴槽等のように大量の水を排水する箇所では排水時間が長くなり利便性が低下する。 In addition, since the height adjusting member protrudes into the drain pipe, the water passing area of the drain pipe is reduced and the drainage performance is deteriorated. Even if a decrease in drainage performance is acceptable in a place that drains a relatively small amount of water, such as the washbasin exemplified in Patent Document 1, in a place that drains a large amount of water, such as a bathtub. Drainage time is long and convenience is reduced.

When viewed from the side, the engaging portion 12 has a rectangular shape. 24.

図４は、フランジ部２０の斜視図である。フランジ部２０は、円筒状をなし、胴部２１の上端部に外向きに張り出す円環板状の上端縁２２、および胴部２１の下端部に内向きに張り出す円環板状の下端縁２３を有する。フランジ部２０は、上部に昇降用段部２４を有している。トラップ部９の防臭用筒体９２は、上方から下端縁２３へ挿入するようにして取り付けられる。 4 is a perspective view of the flange portion 20. FIG. The flange portion 20 has a cylindrical shape, and has an annular plate-shaped upper edge 22 that protrudes outward from the upper end of the body portion 21 and an annular plate-shaped lower end that protrudes inward from the lower end of the body portion 21 . It has a rim 23 . The flange portion 20 has a lifting stepped portion 24 on its upper portion. The deodorizing cylindrical body 92 of the trap portion 9 is attached so as to be inserted into the lower edge 23 from above.

フランジ部２０の昇降用段部２４は、上端縁２２の外周縁部において、上方へ突起するように円弧状に形成されている。昇降用段部２４は、周方向に４等分した各円弧において同一の形状となっている。昇降用段部２４は、上端縁２２と面一である下降段部２４ａ、下降段部２４ａよりも高い上昇段部２４ｂ、および下降段部２４ａと上昇段部２４ｂを連続させる傾斜部２４ｃを有する。また、上昇段部２４ｂの傾斜部２４ｃと反対側の端部には、上昇段部２４ｂよりも１段高い回転規制部２４ｄが設けられている。尚、回転規制部２４ｄの上昇段部２４ｂと反対側の端部は、隣り合う昇降用段部２４の下降段部２４ａに連なっている。 The lifting stepped portion 24 of the flange portion 20 is formed in an arcuate shape so as to protrude upward at the outer peripheral edge portion of the upper edge 22 . The ascending/descending stepped portion 24 has the same shape in each of the four circular arcs that are equally divided in the circumferential direction. The lifting step portion 24 has a descending step portion 24a flush with the upper edge 22, an ascending step portion 24b higher than the descending step portion 24a, and an inclined portion 24c connecting the descending step portion 24a and the ascending step portion 24b. .

The end of the rotation restricting portion 24d on the side opposite to the ascending step portion 24b is connected to the descending step portion 24a of the adjacent ascending/descending step portion 24. As shown in FIG.

傾斜部２４ｃにおける勾配は、ほぼ一定であっても良いし、滑らかに変化してもよい。傾斜部２４ｃと、下降段部２４ａおよび上昇段部２４ｂとの接続部分に丸みを付けて滑らかに接続させることで、止水蓋１０の回転操作を滑らかにすることができる。 The slope of the inclined portion 24c may be substantially constant or may vary smoothly. By rounding the connecting portions between the inclined portion 24c and the descending stepped portion 24a and the ascending stepped portion 24b so as to connect them smoothly, the water stop lid 10 can be rotated smoothly.

排水栓１は、昇降用段部２４の下降段部２４ａに止水蓋１０の係合部１２が接触して閉栓状態となり、上昇段部２４ｂに係合部１２が接触して開栓状態となる。止水蓋１０を閉栓状態から開栓状態へ向かうように回転させたとき、係合部１２は、下降段部２４ａから傾斜部２４ｃを通って上昇段部２４ｂへ移動し、回転規制部２４ｄに当たって止まる。同様に、止水蓋１０を開栓状態から閉栓状態へ向かうように回転させたとき、係合部１２は、上昇段部２４ｂから傾斜部２４ｃを通って下降段部２４ａへ移動し、回転規制部２４ｄに当たって止まる。 The drain plug 1 is closed when the engaging portion 12 of the water cutoff lid 10 comes into contact with the descending stepped portion 24a of the ascending and descending stepped portion 24, and is opened when the engaging portion 12 comes into contact with the ascending stepped portion 24b. Become. When the water shutoff lid 10 is rotated from the closed state to the open state, the engaging portion 12 moves from the descending stepped portion 24a through the inclined portion 24c to the ascending stepped portion 24b and hits the rotation restricting portion 24d. stop. Similarly, when the water shutoff lid 10 is rotated from the open state to the closed state, the engaging portion 12 moves from the ascending stepped portion 24b to the descending stepped portion 24a through the inclined portion 24c, thereby restricting the rotation. It hits the portion 24d and stops.

次に排水栓１の動作について説明する。上述のように排水栓１のフランジ部２０は、浴槽８の排水口８２に固定されている。止水蓋１０は、係合部１２の下面１２ａをフランジ部２０の昇降用段部２４に接触させるようにして取り付けられる。止水蓋１０は、浴槽８の底面８１に交差する上下方向の軸線まわりに回転させることによって、係合部１２が昇降用段部２４上を滑り、上下動する。 Next, the operation of the drain plug 1 will be explained. The flange portion 20 of the drain plug 1 is fixed to the drain port 82 of the bathtub 8 as described above. The water shut-off lid 10 is attached so that the lower surface 12 a of the engaging portion 12 is brought into contact with the lifting stepped portion 24 of the flange portion 20 . By rotating the water stop lid 10 around a vertical axis that intersects the bottom surface 81 of the bathtub 8, the engaging portion 12 slides on the lifting stepped portion 24 and moves up and down.

図５（ａ）および図５（ｂ）は、排水栓１の動きを説明するための模式図である。図５（ａ）に示す状態において、排水栓１は、止水蓋１０の係合部１２がフランジ部２０の下降段部２４ａに接触して閉栓状態となっている。閉栓状態では、止水蓋１０の外周に設けられたパッキン１４が浴槽８の底面８１側の対向面８１ｂに接触し、排水口８２を塞ぐ。 5(a) and 5(b) are schematic diagrams for explaining the movement of the drain plug 1. FIG. In the state shown in FIG. 5( a ), the drain plug 1 is in a closed state with the engaging portion 12 of the water cutoff lid 10 coming into contact with the descending stepped portion 24 a of the flange portion 20 . In the closed state, the packing 14 provided on the outer periphery of the water cutoff lid 10 contacts the opposing surface 81b on the bottom 81 side of the bathtub 8 to close the drain port 82 .

止水蓋１０を回転させて、止水蓋１０の係合部１２を、傾斜部２４ｃを経て上昇段部２４ｂに接触させることで、図５（ｂ）に示す開栓状態となる。また、止水蓋１０を逆方向に回転させることで、図５（ａ）に示す閉栓状態に戻る。 By rotating the water stop cover 10 and bringing the engaging portion 12 of the water stop cover 10 into contact with the ascending stepped portion 24b via the inclined portion 24c, the opened state shown in FIG. 5B is obtained. Further, by rotating the water cutoff lid 10 in the opposite direction, the closed state shown in FIG. 5(a) is restored.

排水栓１は、止水蓋１０の係合部１２およびフランジ部２０の昇降用段部２４が破損した場合には、止水蓋１０およびフランジ部２０を簡単に交換することができ、メンテナンス性が良い。フランジ部２０は、雄螺子２０ａによる螺合を緩めて、浴槽８の底部８１ａから取り外して交換すればよい。また、フランジ部２０の昇降用段部２４に汚れやヌメリが付着した場合でも、昇降用段部２４がフランジ部２０の上部に設けられ、手が届き易い位置に露出しているため、清掃し易くメンテナンス性が良い。 In the drain plug 1, when the engaging portion 12 of the water stop cover 10 and the lifting step portion 24 of the flange portion 20 are damaged, the water stop cover 10 and the flange portion 20 can be easily replaced, and maintainability is improved. is good. The flange portion 20 can be removed from the bottom portion 81a of the bathtub 8 by loosening the male screw 20a and replaced.

Easy and maintainable.

排水栓１は、昇降用段部２４が排水口８２の上流にあり排水口８２よりも外側に形成されており、排水経路中における通水面積を狭めることへの影響が少ないため、排水効率が良好である。特に、浴槽８のように大量の水を排水する箇所では、排水効率が良いことから排水時間が短くなりユーザの利便性が良くなる。 In the drain plug 1, the lifting stepped portion 24 is upstream of the drain port 82 and is formed outside the drain port 82. Since there is little effect on narrowing the water flow area in the drain path, the drain efficiency is improved. Good. In particular, in a place where a large amount of water is drained, such as the bathtub 8, the drainage efficiency is good, so the draining time is shortened, and the user's convenience is improved.
