Description

本発明は、槽体の排水口を開閉する排水栓装置に関するものである。 The present invention relates to a drain plug device that opens and closes the drain outlet of a tank body.

槽体の排水口を開閉する排水栓装置として、排水口の開閉を行う栓蓋と、槽体に取り付けられた操作部と、操作部の操作を栓蓋へと伝達する伝達部を備えた構造が知られている。
特許文献１に記載の排水栓装置は、筒状のアウターチューブと、アウターチューブ内を進退するインナーワイヤから構成された伝達部材を備え、操作部に加えられた押動操作によってインナーワイヤが突出し、栓蓋を押し上げることで排水口を開口させる構造となっている。又、栓蓋の昇降状態はロック機構によって保持され、操作部への操作の都度、排水口の開閉を切り替えることが可能となる。 A drain plug device that opens and closes the drain outlet of a tank body has a structure that includes a plug cover that opens and closes the drain outlet, an operating unit attached to the tank body, and a transmission unit that transmits the operation of the operating unit to the plug cover.
The drain plug device described in Patent Document 1 is equipped with a transmission member consisting of a cylindrical outer tube and an inner wire that advances and retreats within the outer tube, and is structured so that the inner wire protrudes when a pushing operation is applied to the operating part, and the plug lid is pushed up to open the drain. The raised and lowered state of the plug lid is maintained by a locking mechanism, and the drain can be opened and closed each time the operating part is operated.

特開２０１５－６８０７３号公報JP 2015-68073 A

上記特許文献１に記載の排水栓装置において、伝達部材の一端は槽体の縁部又は側面に取り付けられた操作部に接続され、他端は栓蓋の下方に形成された接続部に対して接続される。従って、伝達部材は槽体の下方において、端部が上方を向くように屈曲する必要があるが、槽体の下方に広い空間を確保することが困難な場合、伝達部材の曲げ半径が小さくなってしまう。この時、施工が困難となるとともに、伝達部材はインナーワイヤが進退する際に生じる摩擦が大きくなることから、栓蓋の開閉に必要な応力が増大し、操作性の低下、インナーワイヤの座屈による部材の破損等の問題が生じる。 In the drain plug device described in Patent Document 1, one end of the transmission member is connected to an operating part attached to the edge or side of the tank body, and the other end is connected to a connection part formed below the plug lid. Therefore, the transmission member needs to be bent below the tank body so that its end faces upward, but if it is difficult to secure a large space below the tank body, the bending radius of the transmission member becomes small. In this case, installation becomes difficult, and the friction generated by the transmission member when the inner wire moves back and forth increases, which increases the stress required to open and close the plug lid, resulting in problems such as reduced operability and damage to the member due to buckling of the inner wire.

本発明は上記問題に鑑み、排水栓装置において、施工性を向上させるとともに、栓蓋の開閉に必要な応力を低減させ、操作性の低下や部材の破損を防止する排水栓装置の提供を課題とする。 In view of the above problems, the present invention aims to provide a drain plug device that improves ease of installation, reduces the stress required to open and close the plug cover, and prevents reduced operability and damage to components.

Note that the following description is provided to facilitate understanding of the embodiment, and is not intended to limit or limit the invention.

図１乃至図５に示すように、本発明の排水栓装置は、槽体１、操作部２、ロック機構３、伝達部材４、連結部５、栓蓋９から構成される。 As shown in Figures 1 to 5, the drain plug device of the present invention is composed of a tank body 1, an operating unit 2, a locking mechanism 3, a transmission member 4, a connecting unit 5, and a plug cover 9.

槽体１は浴室に配置される浴槽であり、洗い場に隣接して配置されている。又、槽体１の底壁部１１に形成された排水口１５は縁部に取り付けられた操作部２によって遠隔的に開閉可能となっている。槽体１は平面視矩形を成す底壁部１１と、当該底壁部１１の四隅から上方へ向けて立設された側壁部１２から成り、当該側壁部１２の内、洗い場と隣接する側壁部１２の下端であって、底壁部１１と交差する角部１３において、飛び出し部１４を有している。
飛び出し部１４は、平面視側壁部１２の中央であって、側壁部１２の外側、即ち洗い場側に向けて平面視略コ字状に突出する様に形成されている。又、飛び出し部１４は排水口１５の直上より上方に向けて延設された筒状の挿通部１６が形成されており、当該挿通部１６内に連結部５が配置されている。
図２に示すように、排水口１５は飛び出し部１４の底面を上下方向に貫通する円形の開口であり、槽体１の底壁部１１と飛び出し部１４の底面の内、最も低い位置に形成されている。当該排水口１５は側壁部１２の内側面よりも外側に配置されており、平面視において使用者からは目視不可能となっている。 The tank body 1 is a bathtub that is placed in a bathroom and is disposed adjacent to the washing area. A drain port 15 formed in the bottom wall portion 11 of the tank body 1 can be remotely opened and closed by an operating unit 2 attached to the edge. The tank body 1 is composed of the bottom wall portion 11 that is rectangular in plan view, and side wall portions 12 that are erected upward from the four corners of the bottom wall portion 11, and a protruding portion 14 is formed at a corner portion 13 that intersects with the bottom wall portion 11 at the lower end of the side wall portion 12 adjacent to the washing area.
The protruding portion 14 is formed in the center of the side wall portion 12 in a plan view, and protrudes in a generally U-shape in a plan view toward the outside of the side wall portion 12, i.e., toward the washing area. The protruding portion 14 is formed with a cylindrical insertion portion 16 that extends upward from directly above the drain outlet 15, and the connecting portion 5 is disposed within the insertion portion 16.
2, the drain outlet 15 is a circular opening that passes through the bottom surface of the protruding portion 14 in the vertical direction, and is formed at the lowest position between the bottom wall portion 11 of the tank body 1 and the bottom surface of the protruding portion 14. The drain outlet 15 is located outside the inner surface of the side wall portion 12, and is not visible to the user in a plan view.

操作部２は槽体１の縁部より浴室内に露出するスイッチ部２１を有し、当該スイッチ部２１に対して押動操作が加えられることによって排水栓装置を作動させ、栓蓋９を昇降させることで排水口１５を開閉する。 The operating unit 2 has a switch unit 21 that is exposed to the bathroom from the edge of the tub body 1, and the drain plug device is activated by pressing the switch unit 21, and the drain outlet 15 is opened and closed by raising and lowering the plug cover 9.

ロック機構３は上端より延設された軸がスイッチ部２１裏面に嵌合されており、スイッチ部２１に対する押動操作に伴い内部のギアの噛合及び当該噛合の解除が繰り返されることによって、操作の都度排水口１５の開口状態の保持と、保持の解除を切り替えることが可能となる。又、ロック機構３は内部にリターンスプリングが配置されており、後述するインナーワイヤをスイッチ部２１へと付勢している。 The lock mechanism 3 has a shaft extending from the top end that fits onto the back surface of the switch unit 21, and by repeatedly engaging and disengaging the internal gears as the switch unit 21 is pushed, it is possible to switch between keeping the drain outlet 15 open and releasing the hold each time the switch is pressed. In addition, a return spring is arranged inside the lock mechanism 3, which urges the inner wire, which will be described later, towards the switch unit 21.

伝達部材４は樹脂製且つ筒状のアウターチューブ及びアウターチューブ内に配置された金属製のインナーワイヤから成るレリースワイヤ４１と、レリースワイヤ４１端部に形成された内筒４３及び外筒４４から成る筒部４２を有している。当該伝達部材４は槽体１の外側且つ飛び出し部１４の上方であって、排水口１５の開閉時における栓蓋９の変位方向において約１８０度屈曲し、連結部５の接続部５１と接続されるとともに、連結部５を介して栓蓋９へと操作を伝達する。上記伝達部材４は、操作部２に加えられた押動に連動してインナーワイヤがアウターチューブ内を進退するとともに、当該進退に応じて内筒４３が外筒４４から突出することで操作を伝達する。 The transmission member 4 has a cylindrical outer tube made of resin, a release wire 41 made of a metal inner wire arranged inside the outer tube, and a cylindrical portion 42 made of an inner tube 43 and an outer tube 44 formed at the end of the release wire 41. The transmission member 4 is located outside the tank body 1 and above the protruding portion 14, and is bent approximately 180 degrees in the displacement direction of the plug lid 9 when the drain outlet 15 is opened or closed, and is connected to the connection portion 51 of the connecting portion 5, and transmits the operation to the plug lid 9 via the connecting portion 5. The transmission member 4 transmits the operation by the inner wire moving back and forth inside the outer tube in conjunction with the pushing force applied to the operating portion 2, and the inner tube 43 protruding from the outer tube 44 in response to the moving back and forth.

図３及び図４に示すように、連結部５は伝達部材４と栓蓋９を連結させる部材であって、伝達部材４が接続される接続部５１を有し、連結上部５２、連結中部５４、連結下部５９、支持軸８から構成されている。
連結上部５２は円筒状の部材であって、連結中部５４を覆う様に取り付けられ、その下端には支持軸８を支承するコ字状の保持部５３が形成されているとともに、上端裏面には伝達部材４が接続される接続部５１が形成されている。
接続部５１は操作部２に対する操作に連動して内筒４３が突出した際に当接し、連結上部５２を上下方向に変位させる。尚、接続部５１は排水口１５の開口時における栓蓋９の変位方向であって、本実施形態においては排水口１５及び栓蓋９の上方、即ち排水口５よりも高い位置に設けられる。
連結中部５４は上端に筒部４２が配置される収納部５５が形成されているとともに、下端には連結下部５９と係合する爪部５６が形成されている。収納部５５は側面が開放された半円状であり、筒状のカバー５７が取り付けられることで当該開放された側面が覆われる。尚、筒部４２は収納部５５に収納された状態において、筒部４２は自身の軸を中心として回転可能となっている。又、連結中部５４は下端内部にスプリング５８が配置されている。
連結下部５９は上方に外鍔部６０を有するとともに、下端には飛び出し部１４の挿通部１６内周と当接するＯリングが嵌着されている。又、連結下部５９の外周には連結中部５４の爪部５６と係合する切り欠き６１が形成されている。
支持軸８は飛び出し部１４の上面を貫通し、下端に形成された溝部８１において栓蓋９と係合する棒状であり、上端が保持部５３によって連結上部５２に支承されている。尚、支持軸８は連結中部５４内に配置されたスプリング５８によって栓蓋９側に向けて常に付勢されている。 As shown in Figures 3 and 4, the connecting part 5 is a member that connects the transmission member 4 and the plug lid 9, and has a connection part 51 to which the transmission member 4 is connected, and is composed of an upper connecting part 52, a middle connecting part 54, a lower connecting part 59, and a support shaft 8.
The upper connecting part 52 is a cylindrical member that is attached so as to cover the middle connecting part 54, and a U-shaped retaining part 53 that supports the support shaft 8 is formed at its lower end, while a connection part 51 to which the transmission member 4 is connected is formed on the back surface of the upper end.
The connecting part 51 comes into contact with the inner tube 43 when it is projected in response to an operation of the operating part 2, displacing the upper connecting part 52 in the vertical direction. The connecting part 51 is in the direction of displacement of the plug 9 when the drain outlet 15 is opened, and is provided above the drain outlet 15 and the plug 9, i.e., at a position higher than the drain outlet 5 in this embodiment.
The middle connecting part 54 has a storage part 55 formed at its upper end in which the tubular part 42 is disposed, and a claw part 56 that engages with the lower connecting part 59 is formed at its lower end. The storage part 55 is semicircular with an open side, and the open side is covered by attaching a tubular cover 57. When the tubular part 42 is stored in the storage part 55, the tubular part 42 is capable of rotating around its own axis. A spring 58 is disposed inside the lower end of the middle connecting part 54.
The lower connecting part 59 has an outer flange 60 on the upper side, and an O-ring is fitted to the lower end thereof so as to abut against the inner periphery of the insertion part 16 of the protruding part 14. Also, a notch 61 is formed on the outer periphery of the lower connecting part 59 so as to engage with the claw part 56 of the middle connecting part 54.
The support shaft 8 is rod-shaped and penetrates the upper surface of the protruding portion 14, and engages with the plug 9 in a groove 81 formed at the lower end, and its upper end is supported on the connecting upper portion 52 by a retaining portion 53. The support shaft 8 is constantly biased toward the plug 9 by a spring 58 disposed in the connecting middle portion 54.

上記連結部５は、伝達部材４が挿通されるため、収納部５５下方において側面の一部が開口されている。又、連結部５は飛び出し部１４に取り付けられた状態において、槽体１に対して回動可能となっている。従って、連結部５は操作部２の取り付け位置に合わせて開口の向きを適宜調整することができる。 The connecting part 5 has an opening on a part of its side below the storage part 55 so that the transmission member 4 can be inserted through it. In addition, the connecting part 5 is rotatable with respect to the tank body 1 when attached to the protruding part 14. Therefore, the direction of the opening of the connecting part 5 can be appropriately adjusted to match the attachment position of the operating part 2.

栓蓋９は排水口１５を開閉するパッキンが嵌着された板状の蓋体であって、操作部２からの操作を受けて上下方向に変位する。又、栓蓋９は上面に係合部９１、ガイド部９２、取手９３が形成されている。
係合部９１は切り欠きを有する平面視略Ｃ字状であって、施工完了時には支持軸８が係合されている。尚、係合部９１の内径は支持軸８の外径よりも小径且つ支持軸８下端に形成された溝部８１の外径よりも大径である。
ガイド部９２は係合部９１の両端部から栓蓋９の一端側に向けて平面視扇状に延設されたリブであり、支持軸８を係合部９１へ誘導するよう形成されている。
取手９３は栓蓋９の他端側へと延設され、栓蓋９と支持軸８を着脱させる際に把持することが可能となっている。 The plug lid 9 is a plate-shaped lid body fitted with a packing that opens and closes the drain outlet 15, and is displaced vertically in response to operation from the operating unit 2. In addition, the plug lid 9 has an engagement portion 91, a guide portion 92, and a handle 93 formed on the upper surface.
The engaging portion 91 is generally C-shaped in plan view with a notch, and is engaged with the support shaft 8 when installation is completed. The inner diameter of the engaging portion 91 is smaller than the outer diameter of the support shaft 8 and larger than the outer diameter of the groove 81 formed at the lower end of the support shaft 8.
The guide portions 92 are ribs extending from both ends of the engagement portion 91 toward one end of the plug lid 9 in a fan-like shape in a plan view, and are formed to guide the support shaft 8 to the engagement portion 91.
The handle 93 extends to the other end of the plug 9 and can be grasped when attaching or detaching the plug 9 from the support shaft 8.

上記栓蓋９は係合部９１が支持軸８の溝部８１に係合されることによって連結されており、排水栓装置の作動時において、支持軸８によって上方より引き上げられることで排水口１５を開口するとともに、支持軸８により上方より押し下げられることによって排水口１５を閉塞する。 The plug cover 9 is connected by engaging the engagement portion 91 with the groove portion 81 of the support shaft 8, and when the drain plug device is activated, it opens the drain outlet 15 by being pulled up from above by the support shaft 8, and closes the drain outlet 15 by being pushed down from above by the support shaft 8.

以下に、排水栓装置の組み立てについて説明する。 The assembly of the drain plug device is explained below.

まず、槽体１の縁部に操作部２を取り付ける。この時、操作部２から連続する伝達部材４は下方へ向けて延びている。
次に、上記伝達部材４の端部を約１８０度屈曲させ、上方に向けた状態で連結中部５４の収納部５５に筒部４２を配置し、カバー５７を上方から連結中部５４に覆い被せることで伝達部材４を連結部５に取り付ける。この時、伝達部材４は排水口１５や栓蓋９より上方で屈曲することから、槽体１の外側等の広い空間で伝達部材４を屈曲させることができる。尚、連結部５に取り付けられた状態において、筒部４２は回動可能となっている。
次に、連結上部５２を上方より連結中部５４に覆い被せ、連結中部５４下端にスプリング５８を配置した後、保持部５３に支持軸８を取り付ける。この時、支持軸８はスプリング５８によって下方へ向けて付勢される。
次に、連結下部５９内に連結中部５４を挿入し、爪部５６を切り欠き６１に係合させることで連結部５の組み立てが完了する。
次に、連結下部５９を挿通部１６に挿通し、支持軸８を飛び出し部１４内に突出させた状態で、Ｃ字リング１０によって挿通部１６に連結部５を取り付ける。この時、操作部２が取り付けられた方向に筒部４２や連結部５を回動させることによって、レリースワイヤ４１を無理なく屈曲させることができる。
最後に、栓蓋９を側方から支持軸８の溝部８１に押し付け、栓蓋９の係合部９１を係合させることで施工が完了する。この時、接続部５１は栓蓋９の上方に設けられており、伝達部材４の端部である筒部４２は栓蓋９と接続部５１の間に配置されている。 First, the operating part 2 is attached to the edge of the tank body 1. At this time, the transmission member 4 continuing from the operating part 2 extends downward.
Next, the end of the transmission member 4 is bent approximately 180 degrees, and the tubular portion 42 is placed in the storage portion 55 of the middle connecting portion 54 with the end facing upward, and the cover 57 is placed over the middle connecting portion 54 from above, thereby attaching the transmission member 4 to the connecting portion 5. At this time, since the transmission member 4 is bent above the drain outlet 15 and the plug 9, the transmission member 4 can be bent in a large space such as the outside of the tank body 1. Note that when attached to the connecting portion 5, the tubular portion 42 is rotatable.
Next, the upper connecting part 52 is placed over the middle connecting part 54 from above, and after the spring 58 is placed at the lower end of the middle connecting part 54, the support shaft 8 is attached to the holding part 53. At this time, the support shaft 8 is biased downward by the spring 58.
Next, the middle connecting part 54 is inserted into the lower connecting part 59 and the claw parts 56 are engaged with the notches 61, thereby completing the assembly of the connecting part 5.
Next, the lower connecting part 59 is inserted into the insertion part 16, and with the support shaft 8 protruding into the protruding part 14, the connecting part 5 is attached to the insertion part 16 by the C-ring 10. At this time, the release wire 41 can be bent smoothly by rotating the tube part 42 and the connecting part 5 in the direction in which the operating part 2 is attached.
Finally, the plug cap 9 is pressed against the groove 81 of the support shaft 8 from the side, and the engagement portion 91 of the plug cap 9 is engaged to complete the installation. At this time, the connection portion 51 is provided above the plug cap 9, and the cylindrical portion 42, which is the end portion of the transmission member 4, is disposed between the plug cap 9 and the connection portion 51.

上記排水栓装置は、以下の様に作動する。 The above drain plug device works as follows:

図４に示すように、栓蓋９が下降状態にある時において、栓蓋９はパッキンが排水口１５周縁に当接することによって排水口１５を閉塞している。ここで、スイッチ部２１に対して押動操作が加えられると、インナーワイヤがアウターチューブ内を栓蓋９側へと摺動するとともに、筒部４２の内筒４３が外筒４４より上方へ向けて突出し、連結上部５２の接続部５１を上方に向けて押圧する。押圧された連結上部５２及び支持軸８が上昇すると、支持軸８と係合された栓蓋９が上方より引き上げられることによって上昇し、排水口１５が開口する。又、この時ロック機構３は内部のギアが噛合し、栓蓋９は上昇状態が保持される。
次に、図５に示すように、上記栓蓋９が上昇した状態より再度スイッチ部２１に押動操作が加えられると、ロック機構３内のギアの噛合が解除され、ロック機構３内のリターンスプリングの作用によってインナーワイヤが後退するとともに、内筒４３が下降する。この時、連結下部５９内のスプリング５８によって支持軸８が下方へ向けて付勢され、栓蓋９が下方へ向けて変位するとともに、嵌着されたパッキンが排水口１５の周縁に当接することにより、排水口１５が閉塞される。 As shown in Figure 4, when the plug lid 9 is in the lowered state, the plug lid 9 closes the drain outlet 15 by the packing abutting against the periphery of the drain outlet 15. When the switch 21 is pressed, the inner wire slides inside the outer tube toward the plug lid 9, and the inner tube 43 of the tube portion 42 protrudes upward from the outer tube 44, pressing the connection portion 51 of the connecting upper portion 52 upward. When the pressed connecting upper portion 52 and the support shaft 8 rise, the plug lid 9 engaged with the support shaft 8 is pulled up from above and rises, opening the drain outlet 15. At this time, the internal gear of the locking mechanism 3 meshes, and the plug lid 9 is maintained in the raised state.
5, when the switch portion 21 is pushed again with the plug 9 raised, the gears in the locking mechanism 3 are released from engagement, the inner wire is retracted by the action of the return spring in the locking mechanism 3, and the inner cylinder 43 is lowered. At this time, the support shaft 8 is urged downward by the spring 58 in the lower connecting part 59, the plug 9 is displaced downward, and the fitted packing comes into contact with the periphery of the drain port 15, thereby blocking the drain port 15.

上記本発明の排水栓装置は、接続部５１が栓蓋９や排水口１５よりも上方であって、排水口１５の開口時における栓蓋９の変位方向に設けられており、伝達部材４は接続部５１を内筒４３の突出によって押し上げることで、栓蓋９を変位させて排水口１５を開閉させる構造となっている。又、伝達部材４の端部である筒部４２は栓蓋９と接続部５１の間に配置されている。このように構成することで、伝達部材４を上方に向けて屈曲させ、インナーワイヤを栓蓋９の変位方向に向けて突出させる際に、槽体１の下方の狭い空間に代えて、飛び出し部１４の上方等の広い空間を利用することができる。 In the drain plug device of the present invention, the connection part 51 is located above the plug lid 9 and the drain outlet 15 and is disposed in the direction of displacement of the plug lid 9 when the drain outlet 15 is opened, and the transmission member 4 is structured so that the connection part 51 is pushed up by the protrusion of the inner tube 43, thereby displacing the plug lid 9 and opening and closing the drain outlet 15. In addition, the tube part 42, which is the end part of the transmission member 4, is disposed between the plug lid 9 and the connection part 51. By configuring it in this way, when the transmission member 4 is bent upward and the inner wire is protruded in the direction of displacement of the plug lid 9, a large space such as above the protruding part 14 can be used instead of the narrow space below the tank body 1.

本発明の第一実施形態は以上であるが、本発明は上記第一実施形態の形状に限られるものではなく、発明の要旨を逸脱しない範囲において、種々の設計変更を加えても良い。例えば、上記第一実施形態において、栓蓋は上下方向に変位することによって排水口を開閉していたが、排水栓装置の作動による栓蓋の変位方向は上下方向に限られるものではなく、斜め方向に変位することによって排水口を開閉しても良く、図６に示す第二実施形態のように、略水平方向に変位することによって排水口１５を開閉しても良い。この第二実施形態においては、図６より明らかなように、略水平方向に配置された接続部５１と栓蓋９の間に、伝達部材４の端部である筒部４２が配置され、栓蓋９が略水平方向に変位することで、排水口１５を開閉する構造としている。同様に、伝達部材４の屈曲方向は栓蓋９の変位方向等に応じて適宜設定されても良い。
又、第一実施形態において、排水口は槽体の底壁部に形成されていたが、第二実施形態のように槽体１の底壁部１１と側壁部１２が交差する角部１３に形成されていても良い。
又、本発明の槽体は浴槽に限られるものではなく、洗面ボウルや流し台その他の槽体であっても良い。 The first embodiment of the present invention has been described above, but the present invention is not limited to the shape of the first embodiment, and various design changes may be made within the scope of the invention. For example, in the first embodiment, the plug cover is displaced in the vertical direction to open and close the drain, but the displacement direction of the plug cover due to the operation of the drain plug device is not limited to the vertical direction, and the drain cover may be displaced in an oblique direction to open and close the drain, or the drain cover 15 may be displaced in a substantially horizontal direction as in the second embodiment shown in FIG. 6. In this second embodiment, as is clear from FIG. 6, the cylindrical portion 42, which is the end of the transmission member 4, is disposed between the connection portion 51 and the plug cover 9, which are disposed in a substantially horizontal direction, and the drain cover 15 is opened and closed by displacing the plug cover 9 in a substantially horizontal direction. Similarly, the bending direction of the transmission member 4 may be appropriately set according to the displacement direction of the plug cover 9, etc.
In addition, in the first embodiment, the drain outlet was formed in the bottom wall portion of the tank body, but it may also be formed in the corner portion 13 where the bottom wall portion 11 and the side wall portion 12 of the tank body 1 intersect, as in the second embodiment.
Furthermore, the tank body of the present invention is not limited to a bathtub, but may be a washbowl, a sink, or other tank body.
