Description

本発明は、槽体の排水口に設けられる排水栓装置に関する。   The present invention relates to a drain plug device provided at a drain outlet of a tank body.

従来、排水栓装置としては、槽体(例えば、浴槽や洗面化粧台等)の排水口を開閉可能な栓蓋と、当該栓蓋を上下動可能に支持する支持軸を有してなる支持機構、及び、当該支持機構に連結され押しボタン等からなる操作部の変位を前記支持機構に伝達する伝達部(例えば、ワイヤー)を備えてなるレリースと、排水口の内周において前記支持機構(支持軸)を保持する保持部材とを有するものが知られている。また、排水の流路となる配管を槽体(排水口)に接続するために、外周に雄ねじ部を有する筒状の排水口部材が用いられる。排水口部材は、槽体(排水口)の裏側に配管(例えば、エルボやリング状の管体)を配置した上で、槽体の表側から自身の雄ねじ部を配管の内周に形成された雌ねじ部に螺合し、自身と配管との間で槽体を挟み込むことにより、槽体に配管を接続する(例えば、特許文献1等参照)。   Conventionally, as a drain plug device, a support mechanism having a plug lid that can open and close a drain port of a tank body (for example, a bathtub or a vanity) and a support shaft that supports the plug lid so as to be movable up and down. And a release that includes a transmission unit (for example, a wire) that is connected to the support mechanism and transmits a displacement of an operation unit including a push button to the support mechanism, and the support mechanism (support And a holding member that holds the shaft) are known. Moreover, in order to connect the piping used as the flow path of drainage to a tank body (drainage port), the cylindrical drainage port member which has an external thread part on an outer periphery is used. The drain port member was formed on the inner periphery of the pipe from the front side of the tank body with a pipe (for example, elbow or ring-shaped pipe body) on the back side of the tank body (drain port). The pipe is connected to the tank body by screwing into the female screw portion and sandwiching the tank body between itself and the pipe (see, for example, Patent Document 1).

ところで、一般に排水栓装置は、次の手順で槽体に取付けられる。すなわち、排水口部材を配管に螺合した(配管を槽体に接続した)後に、配管の内部から排水口を通してレリースの一端側(支持機構)を引き出し、支持機構を保持部材に取付ける。そして、保持部材を排水口部材や槽体に取付けるとともに、前記支持機構の支持軸に栓蓋を取付けることで排水栓装置が槽体に取付けられる。尚、保持部材の内部に支持軸が設けられ、保持部材の一部と支持軸とにより支持機構が構成される場合(つまり、支持機構と保持部材とが一体化される構成の場合)には、配管の内部から排水口を通して伝達部の一端側が引き出され、引き出された伝達部の一端部が支持機構に接続された上で、保持部材の外周部分が排水口部材や槽体に取付けられる。   By the way, the drain plug device is generally attached to the tank body by the following procedure. That is, after the drain port member is screwed into the pipe (the pipe is connected to the tank body), one end side (support mechanism) of the release is pulled out from the inside of the pipe through the drain port, and the support mechanism is attached to the holding member. And while attaching a holding member to a drain port member or a tank body, a drain plug apparatus is attached to a tank body by attaching a plug lid to the support shaft of the said support mechanism. When a support shaft is provided inside the holding member and the support mechanism is configured by a part of the holding member and the support shaft (that is, when the support mechanism and the holding member are integrated), The one end side of the transmission part is pulled out from the inside of the pipe through the drain port, and the outer peripheral part of the holding member is attached to the drain port member or the tank body after one end part of the pulled out transmission unit is connected to the support mechanism.

しかしながら、手の届かない配管内からレリースの一端側(支持機構や伝達部)を引き出すことは難しいため、多くの手間や時間を要し、取付作業者に多大な負担を強いることとなってしまうおそれがある。また、レリースの引き出し時に、伝達部が切れたり折れ曲がったりしてしまう等、レリースなどの部材に破損が生じてしまうおそれがある。   However, since it is difficult to pull out one end side (support mechanism or transmission part) of the release from the pipe that is out of reach, it takes a lot of labor and time, and it imposes a great burden on the installation worker. There is a fear. Further, when the release is pulled out, there is a risk that the member such as the release may be damaged, such as the transmission part being cut or bent.

そこで、取付作業性の向上や部材の破損防止を図るべく、保持部材の外周側に雄ねじ部を有する筒状部を設けるとともに、当該筒状部を配管に螺合することで、保持部材及びこれに保持される支持機構(保持部材及び支持機構が一体化される場合には、当該一体化されたものに伝達部が接続されたもの)を予め配管に取付けておき(すなわち、支持機構が予め引き出された状態としておき)、その上で、排水口部材を配管に螺合することにより配管を槽体に接続する技術が提案されている(例えば、特許文献2等参照)。ところが、当該技術では、配管に対して排水口部材を螺合した後に、排水口部材の下方に配置された保持部材を上方側へと移動させ、筒状部の上面部を排水口部材の下面部に接触させることにより、支持機構ひいてはこれに取付けられる栓蓋が正規の位置に配置される。すなわち、排水口部材を螺合した後に、排水口部材よりも下側(奥側)に配置される保持部材のみを移動させる必要がある。従って、取付作業性を十分に向上させることができないおそれがある。   Therefore, in order to improve the mounting workability and prevent damage to the member, a cylindrical portion having a male screw portion is provided on the outer peripheral side of the holding member, and the cylindrical portion is screwed into the pipe, thereby holding the holding member and the same. A support mechanism (if the holding member and the support mechanism are integrated) is attached to the pipe in advance (that is, the support mechanism is previously connected). A technique has been proposed in which the pipe is connected to the tank body by screwing the drain port member into the pipe (for example, see Patent Document 2). However, in this technique, after the drain port member is screwed to the pipe, the holding member disposed below the drain port member is moved upward, and the upper surface portion of the cylindrical portion is moved to the lower surface of the drain port member. By contacting the part, the support mechanism and thus the stopper lid attached to the support mechanism are arranged at a normal position. That is, after screwing the drain port member, it is necessary to move only the holding member disposed below (the back side) the drain port member. Therefore, there is a possibility that the mounting workability cannot be sufficiently improved.

尚、保持部材を配管に対して最終的に配置されるであろう位置に予め配置しておくことも考えられるが、この場合には、槽体における寸法バラツキ等に対応して保持部材を移動させることができなくなる。従って、寸法バラツキ等に伴い、槽体に対する保持部材や支持機構の配置位置にずれが生じてしまい、槽体に対する栓蓋のシール性(密着性)や排水能力の低下を招いてしまうおそれがある。   It is possible to arrange the holding member in advance at a position where it will be finally arranged with respect to the piping. In this case, however, the holding member is moved in accordance with the dimensional variation in the tank body. Can not be made. Therefore, due to dimensional variations and the like, there is a shift in the arrangement position of the holding member and the support mechanism with respect to the tank body, and there is a possibility that the sealing performance (adhesiveness) of the stopper lid with respect to the tank body and the drainage capacity may be reduced. .

これに対して、配管に保持部材(筒状部)を螺合し、保持部材及び支持機構を配管に対して予め取付けておくとともに、排水口部材の取付時に、排水口部材を保持部材と一体化させた上で、一体化された排水口部材及び保持部材を配管に螺合することで、槽体に対する配管の接続、及び、保持部材や支持機構の正規位置への配置を同時に行う技術が提案されている(例えば、特許文献3等参照)。   In contrast, the holding member (cylindrical portion) is screwed into the pipe, and the holding member and the support mechanism are attached to the pipe in advance, and the drain port member is integrated with the holding member when the drain port member is attached. The technology to simultaneously connect the pipe to the tank body and place the holding member and the support mechanism at the normal positions by screwing the integrated drain port member and holding member into the pipe It has been proposed (see, for example, Patent Document 3).

しかしながら、当該技術によれば、排水口部材の螺合後における保持部材の移動は不要となるものの、故障対応等のメンテナンスを行う際において、保持部材や支持機構を取外す必要が生じた場合に、排水口部材を取外さなければ、保持部材等を取外すことができない。従って、メンテナンス性に劣る。   However, according to the technique, the movement of the holding member after screwing of the drain port member is not necessary, but when performing maintenance such as failure handling, it is necessary to remove the holding member and the support mechanism, The holding member or the like cannot be removed unless the drain port member is removed. Therefore, it is inferior to maintainability.

本発明は、上記事情を鑑みてなされたものであり、その目的は、支持機構を配管に対して予め取付可能とすること等により、取付作業性等を飛躍的に高めることができ、かつ、排水口部材を取外すことなく、支持機構を保持するアタッチメント部材を取外し可能とすることで、メンテナンス性の向上を図ることができる排水栓装置を提供することにある。   The present invention has been made in view of the above circumstances, and its purpose is to make it possible to dramatically improve the mounting workability by making the support mechanism attachable to the pipe in advance, and the like. An object of the present invention is to provide a drain plug device capable of improving the maintainability by making it possible to remove the attachment member that holds the support mechanism without removing the drain port member.

以下、上記目的を解決するのに適した各手段につき、項分けして説明する。なお、必要に応じて対応する手段に特有の作用効果を付記する。   In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A drain plug device attached to the drain of the tank body and connected to a predetermined pipe,
A first male screw portion that is inserted into the drainage port and can be screwed into a female screw portion formed on the inner periphery of the pipe is provided on the outer periphery, and the first male screw portion is screwed into the female screw portion, A cylindrical drainage port member connecting the pipe to the tank body by sandwiching the tank body with the pipe,
An annular ring member that has a second male screw portion that can be screwed to the female screw portion on the outer periphery, and is disposed coaxially with the drain port member below the drain port member;
A support shaft to which a plug lid provided at the drain outlet is attached, and a support mechanism for supporting the plug lid so as to be movable up and down;
A holding portion that directly or indirectly holds the support shaft, and an attachment member that has an arm portion that extends from the holding portion toward the outside and is attached to the ring member,
On the lower side of the drain port member, a locking portion that can be locked to the locked portion provided on the upper side of the ring member is provided,
In a state where the locking portion is locked to the locked portion, the relative rotation of the ring member with respect to the drain port member is restricted,
The screw pitch of the first male screw portion and the screw pitch of the second male screw portion are equalized, the locking portion is locked to the locked portion, and the upper surface portion of the ring member is In a state where the lower surface portion of the drain port member is in contact, the screw thread of the second male screw part is continuous with the screw thread of the first male screw part,
The drain plug device according to claim 1, wherein the attachment member is attachable / detachable to / from the ring member from above the drain port member.

尚、「前記第1雄ねじ部のねじ山に対して前記第2雄ねじ部のねじ山が連続する螺旋状とされ」とあるのは、第1雄ねじ部のねじ山と第2雄ねじ部のねじ山とが隙間なく連続する螺旋状とされている場合のみならず、両ねじ山の間に若干の隙間がある場合も含む。   Note that “the screw thread of the second male screw part is continuous with the screw thread of the first male screw part” means that the screw thread of the first male screw part and the screw thread of the second male screw part. Including a case where there is a slight gap between both screw threads.

また、栓蓋を支持する支持軸をアタッチメント部材の保持部の内部に設け、保持部及び支持軸により支持機構を構成することとしてもよい。すなわち、支持機構及びアタッチメント部材を一体化してもよい。   Moreover, it is good also as providing the support shaft which supports a stopper lid in the inside of the holding part of an attachment member, and comprising a support mechanism with a holding part and a support shaft. That is, the support mechanism and the attachment member may be integrated.

上記手段1によれば、支持機構を保持する(又は、支持機構が一体化された)アタッチメント部材が取付けられたリング部材を、配管に予め螺合しておくことで、配管に対して支持機構を予め取付けておくことができる。このため、配管内から支持機構等を引き出すといった面倒な作業が不要となり、取付作業性の向上や支持機構の引き出し時における部材の破損防止を図ることができる。   According to the above-mentioned means 1, the ring mechanism to which the attachment member that holds the support mechanism (or the support mechanism is integrated) is attached in advance to the pipe so that the support mechanism is attached to the pipe. Can be attached in advance. For this reason, the troublesome work of pulling out the support mechanism and the like from the inside of the pipe is not required, and it is possible to improve the mounting workability and prevent the member from being damaged when the support mechanism is pulled out.

さらに、上記手段1によれば、第1雄ねじ部のねじピッチ、及び、第2雄ねじ部のねじピッチが等しくされるとともに、係止部を被係止部に係止し、かつ、リング部材の上面部に排水口部材の下面部を接触させた状態において、第1雄ねじ部のねじ山に対して第2雄ねじ部のねじ山が連続する螺旋状とされている。従って、配管に対してリング部材をその最終的な配置位置よりも手前側(より詳しくは、排水口部材を配管に螺合することなく、排水口部材の下面部をリング部材の上面部に接触可能な位置)に螺合した状態において、被係止部に対して係止部を係止し排水口部材に対するリング部材の相対回転を規制した上で、配管に対して排水口部材を相対回転させることにより、排水口部材とともにリング部材を配管に螺合することができる。そして、排水口部材を最終的な配置位置に設けた(配管を槽体に接続した)ときに、リング部材は、排水口部材の下面部を基準とする適切な配置位置に設けられ、ひいては栓蓋の開口量(ストローク量)が安定することとなる。   Further, according to the means 1, the screw pitch of the first male screw portion and the screw pitch of the second male screw portion are equalized, the locking portion is locked to the locked portion, and the ring member In a state in which the lower surface portion of the drain port member is in contact with the upper surface portion, the screw thread of the second male screw portion is continuous with the screw thread of the first male screw portion. Therefore, the ring member is placed in front of the final arrangement position with respect to the pipe (more specifically, the lower surface portion of the drain port member is brought into contact with the upper surface portion of the ring member without screwing the drain port member into the pipe. In a state where it is screwed into a possible position), the locking portion is locked to the locked portion and the relative rotation of the ring member with respect to the drain port member is restricted, and then the drain port member is rotated relative to the pipe. By doing so, the ring member can be screwed into the pipe together with the drain port member. When the drain port member is provided at the final arrangement position (when the pipe is connected to the tank body), the ring member is provided at an appropriate arrangement position with respect to the lower surface portion of the drain port member, and as a result The opening amount (stroke amount) of the lid is stabilized.

例えば、栓蓋が槽体に密着することで排水口を閉鎖する構成の場合、排水口部材は、配管との間で槽体を挟み込む際に槽体の表面に接触するが、槽体の表面は裏面等と比較して通常精度よく形成される。そのため、同種の槽体において、栓蓋によるシール位置から、排水口部材が接触する表面までの距離にバラツキが生じてしまうことが極めて少ない。従って、排水口部材を最終的な配置位置に設けたときに、排水口部材は栓蓋によるシール位置に対して一定の位置に設けられ、ひいては排水口部材の下面部に接触するリング部材、及び、これに取付けられる支持機構の配置位置も前記シール位置に対して一定の位置に設けられる。その結果、栓蓋の開口量(ストローク量)を安定させることができる。   For example, in the case of a configuration in which the drain lid is closed by the stopper lid being in close contact with the tank body, the drain port member contacts the surface of the tank body when sandwiching the tank body with the pipe, but the surface of the tank body Is usually formed more accurately than the back surface. Therefore, in the same kind of tank body, there is very little variation in the distance from the sealing position by the stopper lid to the surface that the drain port member contacts. Therefore, when the drain port member is provided at the final arrangement position, the drain port member is provided at a fixed position with respect to the sealing position by the plug lid, and as a result, a ring member that contacts the lower surface portion of the drain port member, and The arrangement position of the support mechanism attached to this is also provided at a fixed position with respect to the seal position. As a result, the opening amount (stroke amount) of the plug lid can be stabilized.

また、栓蓋が排水口部材に密着することで排水口を閉鎖する構成の場合、上述の通り、リング部材は排水口部材の下面部に接触しているため、排水口部材とリング部材との相対配置位置は変化せず、ひいては、排水口部材に対して支持機構や栓蓋が一定の位置に配置されることとなる。そのため、栓蓋の開口量(ストローク)が安定することとなる。このように上記手段1によれば、排水口部材を最終的な配置位置に設けたときに、リング部材は適切な配置位置に設けられることとなる。そのため、排水口部材の取付後に、リング部材を移動させる必要がなくなり、取付作業性を一層向上させることができる。   In addition, in the case of a configuration in which the plug lid is in close contact with the drain port member and the drain port is closed as described above, the ring member is in contact with the lower surface portion of the drain port member. The relative arrangement position does not change, and as a result, the support mechanism and the plug lid are arranged at a fixed position with respect to the drain port member. Therefore, the opening amount (stroke) of the plug lid is stabilized. Thus, according to the means 1, when the drain port member is provided at the final arrangement position, the ring member is provided at an appropriate arrangement position. Therefore, it is not necessary to move the ring member after the drain port member is attached, and the attachment workability can be further improved.

加えて、上記手段1によれば、アタッチメント部材が、排水口部材の上方からリング部材に対して取付・取外可能とされている。従って、リング部材からアタッチメント部材を取外すことで、排水口部材を配管から取外すことなく、アタッチメント部材や支持機構を容易に取外すことができる。その結果、メンテナンス性の向上を図ることができる。   In addition, according to the means 1, the attachment member can be attached to and detached from the ring member from above the drain port member. Therefore, by removing the attachment member from the ring member, it is possible to easily remove the attachment member and the support mechanism without removing the drain port member from the pipe. As a result, maintenance can be improved.

手段2.前記排水口部材の中心軸方向に沿った、前記被係止部に対する前記係止部の係止代の高さが、前記第1雄ねじ部のねじピッチよりも小さくされていることを特徴とする手段1に記載の排水栓装置。   Mean 2. The height of the locking margin of the locking portion relative to the locked portion along the central axis direction of the drain port member is smaller than the screw pitch of the first male screw portion. The drain plug device according to means 1.

配管に対する排水口部材やリング部材の螺合時において、リング部材の上面部が排水口部材の下面部から第1雄ねじ部のねじピッチ分だけ離れている場合にも、排水口部材及びリング部材を配管に対して同時に螺合することが可能である。しかしながら、このような状態で排水口部材等を螺合した場合には、リング部材が所定の位置よりも前記ねじピッチ分だけ下方側に配置されてしまい、リング部材ひいては支持機構の上下方向における位置が正規位置からずれてしまうおそれがある。   Even when the upper surface of the ring member is separated from the lower surface of the drain port member by the thread pitch of the first male screw portion when the drain port member or the ring member is screwed to the pipe, the drain port member and the ring member are It is possible to screw onto the pipe at the same time. However, when the drain port member or the like is screwed in such a state, the ring member is disposed below the predetermined position by the screw pitch, and the ring member and thus the position of the support mechanism in the vertical direction is arranged. May deviate from the normal position.

この点、上記手段2によれば、被係止部に対する係止部の係止代の高さが、第1雄ねじ部のねじピッチよりも小さくされている。つまり、被係止部に対して係止部が係止されている状態であれば、排水口部材とリング部材との間にねじピッチ以上の隙間が生じないように構成されている。ここで、排水口部材とリング部材との間に隙間があるものの、当該隙間の大きさがねじピッチよりも小さい場合には、排水口部材及びリング部材を同時に配管に対して螺合することはできない。そのため、上記手段2において、被係止部に対して係止部が係止され、かつ、排水口部材及びリング部材を同時に配管に対して螺合できたのであれば、リング部材は、自身の上面部が排水口部材の下面部に接触している状態で配管に螺合されていることとなる。従って、上記手段2によれば、リング部材が所定の位置よりもねじピッチ分だけ下方側に配置されてしまうという事態をより確実に防止することができる。その結果、リング部材ひいては支持機構を所定の位置に対してより確実に配置することができる。   In this respect, according to the means 2, the height of the locking margin of the locking portion with respect to the locked portion is made smaller than the screw pitch of the first male screw portion. That is, if the locking part is locked with respect to the locked part, the gap between the drain port member and the ring member is not generated more than the screw pitch. Here, although there is a gap between the drain port member and the ring member, when the size of the gap is smaller than the screw pitch, the drain port member and the ring member can be screwed together with the pipe at the same time. Can not. Therefore, in the said means 2, if a latching part is latched with respect to a to-be-latched part, and if the drain port member and the ring member could be screwed together with piping simultaneously, a ring member will be own. It will be screwed together with piping in the state which the upper surface part has contacted the lower surface part of the drain port member. Therefore, according to the said means 2, the situation where a ring member will be arrange | positioned below only a screw pitch rather than a predetermined position can be prevented more reliably. As a result, the ring member and thus the support mechanism can be more reliably arranged with respect to a predetermined position.

手段3.前記排水口部材及び前記リング部材の少なくとも一方には、前記係止部を前記被係止部に係止した状態において、前記排水口部材に対する前記リング部材の上下方向に沿った相対移動を規制する移動規制手段が設けられることを特徴とする手段1又は2に記載の排水栓装置。   Means 3. At least one of the drain port member and the ring member regulates relative movement along the vertical direction of the ring member with respect to the drain port member in a state where the locking portion is locked to the locked portion. The drain plug device according to means 1 or 2, further comprising movement restriction means.

上記手段3によれば、係止部を被係止部に係止した状態では、排水口部材に向けて上方側への力を加えたとしても、リング部材から排水口部材が外れなくなる。従って、配管に対する排水口部材及びリング部材の螺合時に、リング部材から排水口部材が誤って外れてしまうことがなくなり、取付作業性をより一層向上させることができる。   According to the means 3, in the state where the locking portion is locked to the locked portion, even if an upward force is applied toward the drain port member, the drain port member cannot be detached from the ring member. Therefore, when the drain port member and the ring member are screwed to the pipe, the drain port member is not accidentally detached from the ring member, and the mounting workability can be further improved.

尚、弾性部材は、リング部材と別体で設けてもよいし、リング部材と一体で設けてもよい。   The elastic member may be provided separately from the ring member or may be provided integrally with the ring member.

上記手段4によれば、支持機構を保持する(又は、支持機構と一体化された)アタッチメント部材が取付けられたリング部材を、配管に予め取付けておくことができるため、配管内から支持機構等を引き出すといった面倒な作業が不要となり、取付作業性を向上させることができる。   According to the above means 4, the ring member to which the attachment member for holding the support mechanism (or integrated with the support mechanism) is attached can be attached in advance to the pipe. This eliminates the troublesome work of pulling out and improves the mounting workability.

また、上記手段4によれば、排水口部材によりリング部材を下方側へと押しつつ、配管に対して排水口部材を螺合することができる。そして、弾性部材からの付勢力により、リング部材の上面部は排水口部材の下面部に接触することとなり、排水口部材を最終的な配置位置に設けた(配管を槽体に接続した)ときには、リング部材は排水口部材の下面部を基準とする適切な配置位置に設けられることとなる。従って、排水口部材の取付後に、リング部材を適切な配置位置へと移動させる必要はなく、取付作業性を一層向上させることができる。   Moreover, according to the said means 4, a drain port member can be screwed together with piping, pushing a ring member to a downward side with a drain port member. Then, due to the urging force from the elastic member, the upper surface portion of the ring member comes into contact with the lower surface portion of the drain port member, and when the drain port member is provided at the final arrangement position (when the pipe is connected to the tank body). The ring member is provided at an appropriate arrangement position based on the lower surface portion of the drain port member. Therefore, it is not necessary to move the ring member to an appropriate arrangement position after the drain port member is attached, and the attachment workability can be further improved.

加えて、上記手段4によれば、アタッチメント部材が、リング部材に対して排水口部材の上方から取付・取外可能とされている。従って、リング部材からアタッチメント部材を取外すことで、排水口部材を配管から取外すことなく、アタッチメント部材や支持機構を容易に取外すことができる。その結果、メンテナンス性を向上させることができる。   In addition, according to the means 4, the attachment member can be attached to and detached from the ring member from above the drain port member. Therefore, by removing the attachment member from the ring member, it is possible to easily remove the attachment member and the support mechanism without removing the drain port member from the pipe. As a result, maintainability can be improved.

尚、上記手段1のように、排水口部材及びリング部材を配管に対して同時に螺合可能とするためには、排水口部材の下面部にリング部材の上面部を接触させたときに、排水口部材の第1雄ねじ部に対して、リング部材の第2雄ねじ部が連続する螺旋状となるように位置合わせして組付ける必要がある。しかし、この構成を満たすためには、例えば、被係止部を係止部の位置を合わせた上で第2雄ねじ部を形成するなど、被係止部に対して一定の位置にねじ山が位置するように第2雄ねじ部を形成する等の必要があり、リング部材の製造に困難が生じてしまうおそれがある。また、係止部及び被係止部が複数設けられる場合には、両ねじ部が連続する螺旋状となるように、係止部が係止される被係止部を選択する必要がある。   In order to enable the drain port member and the ring member to be screwed to the pipe simultaneously as in the above means 1, the drainage member is drained when the upper surface portion of the ring member is brought into contact with the lower surface portion of the drain port member. It is necessary to align and assemble the second male screw portion of the ring member so that the second male screw portion of the ring member has a continuous spiral shape. However, in order to satisfy this configuration, for example, the second threaded portion is formed after aligning the position of the locked portion with the threaded portion at a certain position with respect to the locked portion. It is necessary to form the second male screw portion so as to be positioned, and there is a possibility that difficulty in manufacturing the ring member may occur. Further, when a plurality of locking portions and locked portions are provided, it is necessary to select a locked portion to which the locking portions are locked so that both screw portions have a continuous spiral shape.

この点、上記手段4によれば、リング部材の外周に配管に対する螺合用の雄ねじ部を設ける必要はなく、例えば、平滑状とすることができる。従って、リング部材を容易に製造することができ、生産性の向上を図ることができる。また、排水口部材の螺合時に、被係止部に対して係止部を係止させることが不要となり、ひいては両雄ねじ部が連続した螺旋状となるように、係止部の係止される被係止部を選択するといった面倒な作業も生じ得ない。従って、取付作業性を一層向上させることができる。   In this regard, according to the above means 4, it is not necessary to provide a male thread portion for screwing with respect to the pipe on the outer periphery of the ring member. Therefore, a ring member can be manufactured easily and productivity can be improved. Further, when the drain port member is screwed, it is not necessary to lock the locking portion with respect to the locked portion, and as a result, the locking portion is locked so that both male screw portions have a continuous spiral shape. The troublesome work of selecting the locked portion to be performed cannot occur. Therefore, the mounting workability can be further improved.

手段5.前記配管内における前記リング部材の上下方向の相対移動可能範囲を規定する移動範囲規定手段を備えることを特徴とする手段4に記載の排水栓装置。   Means 5. The drain plug device according to claim 4, further comprising movement range defining means for defining a relative movable range in the vertical direction of the ring member in the pipe.

上記手段5によれば、移動範囲規定手段により、配管の上方側開口からリング部材が外れてしまったり、弾性部材からの付勢力によりリング部材が過度に上方側に配置されてしまったりするといった事態が生じなくなる。そのため、槽体へと取付時等における排水栓装置の取扱いが容易になるとともに、取付作業性の一層の向上を図ることができる。   According to the means 5, the movement range defining means causes the ring member to be removed from the upper opening of the pipe, or the ring member is excessively disposed on the upper side by the biasing force from the elastic member. Will not occur. Therefore, it becomes easy to handle the drain plug device at the time of mounting on the tank body, and the mounting workability can be further improved.

尚、「移動範囲規定手段」は、例えば、配管(又はリング部材)に設けられ、上下方向に延びる溝部と、リング部材(又は配管)に設けられ、前記溝部内に配置される突出部とにより構成することができる。   The “movement range defining means” is, for example, provided in a pipe (or ring member) by a groove extending in the vertical direction, and a protrusion provided in the groove and provided in the ring member (or pipe).

Therefore, the troublesome work of pulling out the support mechanism and the like from the inside of the pipe becomes unnecessary, and the mounting workability can be improved. Further, by removing the attachment member from the ring member, the attachment member and the support mechanism can be easily removed without removing the drain port member from the pipe, and the maintainability can be improved.

さらに、上記手段6によれば、自身の上面部が排水口部材の下面部に接触するようにしてリング部材を排水口部材に取付けた上で、配管に対して排水口部材を螺合することができる。そして、排水口部材を配管に対して螺合することで、排水口部材とともに、これに取付けられたリング部材が配管内に入り込み、排水口部材を最終的な配置位置に設けたときに、リング部材は排水口部材の下面部を基準とする適切な配置位置に設けられることとなる。従って、排水口部材の取付後に、リング部材を適切な配置位置へと移動させる必要はなく、取付作業性を一層向上させることができる。   Further, according to the means 6, the ring member is attached to the drain port member so that the upper surface portion thereof contacts the lower surface portion of the drain port member, and the drain port member is screwed to the pipe. Can do. When the drain port member is screwed into the pipe, the ring member attached to the drain port member enters the pipe and the drain port member is provided at the final arrangement position. A member will be provided in the suitable arrangement position on the basis of the lower surface part of a drain outlet member. Therefore, it is not necessary to move the ring member to an appropriate arrangement position after the drain port member is attached, and the attachment workability can be further improved.

また、上記手段4と同様に、リング部材の外周に雄ねじ部を設ける必要がないため、リング部材を容易に製造することができ、生産性の向上を図ることができる。また、排水口部材の螺合時に、被係止部に対して係止部を係止させることが不要となり、ひいては雄ねじ部が連続した螺旋状となるように、係止部の係止される被係止部を選択するといった面倒な作業も生じ得ない。従って、取付作業性を一層向上させることができる。   Further, similarly to the above means 4, since it is not necessary to provide a male screw portion on the outer periphery of the ring member, the ring member can be easily manufactured, and productivity can be improved. Further, when the drain port member is screwed, it becomes unnecessary to lock the locking portion with respect to the locked portion, and the locking portion is locked so that the male screw portion becomes a continuous spiral shape.

尚、「前記湾曲部が前記凸部に対してほぼ接触する」とあるのは、湾曲部に対して凸部が隙間なく接触している場合だけでなく、湾曲部と凸部との間に若干の隙間が形成されている場合も含むという趣旨である。   Note that “the curved portion substantially contacts the convex portion” is not only when the convex portion is in contact with the curved portion without any gap, but also between the curved portion and the convex portion. This includes the case where a slight gap is formed.

上記手段7によれば、排水口部材の内周には、複数の凸部が設けられており、配管に排水口部材を螺合する際には、前記凸部に取付用の工具を引掛けることができる。従って、配管に対する排水口部材の螺合を一層容易に行うことができ、取付作業性をさらに高めることができる。   According to the above means 7, a plurality of convex portions are provided on the inner periphery of the drain port member, and when the drain port member is screwed into the pipe, a mounting tool is hooked on the convex portion. be able to.

That is, the curved portion and the convex portion are configured to be continuous in an annular shape. Therefore, similarly to the case where the above-described annular portion is provided, the strength of the arm portion can be improved, and breakage of the arm portion can be prevented. Further, since the bending portion is arranged at a position shifted from the convex portion in the circumferential direction, the inner diameter of the bending portion (the diameter from the outer peripheral surface of the holding portion to the inner peripheral surface of the bending portion is not disturbed). The distance along the direction) can be increased as much as possible. Therefore, the water flow area of the drainage channel formed inside the curved portion can be made sufficiently large, and an excellent drainage capacity can be realized.

上記手段8によれば、排水口部材に設けられた凸部が、径方向内側に向けて突出するとともに、排水口部材の上面部から上方側に突出するように構成されている。従って、凸部に対して取付用の工具をより確実に係止させることができ、配管に対する排水口部材の螺合をより確実に、かつ、より容易に行うことができる。   According to the said means 8, while the convex part provided in the drain outlet member protrudes toward radial inside, it is comprised so that it may protrude from the upper surface part of a drain outlet member upward. Therefore, the attachment tool can be more reliably locked to the convex portion, and the drainage port member can be screwed into the pipe more reliably and more easily.

手段9.前記アタッチメント部材が取付けられた前記リング部材の上面部に、前記排水口部材の下面部を接触させた状態において、前記湾曲部の内面と前記凸部の内面とが面一とされることを特徴とする手段7又は8に記載の排水栓装置。   Means 9.

The width is equal to 24. Further, as described above, since the width of at least one locking portion 24 is different from the width of the other locking portions 24, each locking portion 24 is locked to the locked portion 32. In addition, the ring member 3 is not combined with the drain port member 2 in a state of being shifted from the predetermined position in the circumferential direction, and the arrangement position of the ring member 3 with respect to the drain port member 2 is uniquely determined. . And in this embodiment, in the state which the latching | locking part 24 was latched by the to-be-latched part 32, and the lower surface part of the drain port member 2 was made to contact the upper surface part of the ring member 3, said 1st male thread part The second male threaded portion 31 is configured to have a continuous spiral with respect to 22 threaded threads. Accordingly, the drainage port member 2 is relative to the pipe 102 in a state where the latching portion 24 is latched to the latched portion 32 and the lower surface portion of the drainage port member 2 is in contact with the upper surface portion of the ring member 3. By rotating, the ring member 3 together with the drain port member 2 can be screwed to the pipe 102 at the same time.

加えて、本実施形態では、図4に示すように、排水口部材2の中心軸方向(上下方向)に沿った、被係止部32に対する係止部24の係止代の高さXが、第1雄ねじ部22のねじピッチよりも小さくされている。すなわち、被係止部32に対して係止部24が係止されている状態であれば、排水口部材2とリング部材3との間に前記ねじピッチ以上の隙間が生じないように構成されている。   In addition, in this embodiment, as shown in FIG. 4, the height X of the locking allowance of the locking portion 24 with respect to the locked portion 32 along the central axis direction (vertical direction) of the drain port member 2 is The screw pitch of the first male screw portion 22 is smaller. That is, if the locking portion 24 is locked with respect to the locked portion 32, a gap larger than the screw pitch is not generated between the drain port member 2 and the ring member 3. ing.

図3に戻り、リング部材3の内周のうち、排水口部材2とリング部材3とを組み合わせた状態において前記凸部23とは周方向にずれた位置には、リング部材3の周方向に沿って等間隔に複数の段差部33が設けられている。また、リング部材3のうち段差部33同士の間に位置する部位は、段差部33が形成された部位の内周面よりも径方向内側に向けて若干突出した肉厚部34となっている。   Returning to FIG. 3, in the inner periphery of the ring member 3, the drain port member 2 and the ring member 3 are combined in the circumferential direction of the ring member 3 at a position shifted in the circumferential direction from the convex portion 23. A plurality of step portions 33 are provided at equal intervals along. Moreover, the part located between the level | step-difference parts 33 among the ring members 3 becomes the thick part 34 which protruded slightly toward the radial inside rather than the internal peripheral surface of the site | part in which the level | step-difference part 33 was formed. .

前記アタッチメント部材4は、所定の樹脂(例えば、POM等)により形成されるとともに、排水口部材2及びリング部材3の内周側においてリング部材3に取付けられており、図5に示すように、保持部41とアーム部42とを備えている。   The attachment member 4 is formed of a predetermined resin (for example, POM) and is attached to the ring member 3 on the inner peripheral side of the drain port member 2 and the ring member 3, as shown in FIG. A holding part 41 and an arm part 42 are provided.

保持部41は、筒状をなし、自身の内周において前記支持機構5を保持している。具体的には、保持部41は、自身の内周面上端側に径方向内側に突出する上側突出部41Aを備え、自身の内周面下端側に径方向内側に向けて突出する下側突出部41B(図1参照)を備えている。そして、両突出部41A,41Bで支持機構5を挟み込むことにより、保持部41は、支持機構5を保持している。尚、本実施形態において、保持部41には、その中心軸方向に沿って延びるスリット41Cが設けられている。当該スリット41Cにより、保持部41に対してその後端側開口から支持機構5を挿通する際に、保持部41の後端側開口を容易に開くことができるようになっている。   The holding part 41 has a cylindrical shape and holds the support mechanism 5 on its inner circumference. Specifically, the holding portion 41 includes an upper protruding portion 41A that protrudes radially inward on the upper end side of the inner peripheral surface thereof, and a lower protrusion that protrudes radially inward on the lower end side of the inner peripheral surface thereof. A portion 41B (see FIG. 1) is provided. And the holding part 41 hold | maintains the support mechanism 5 by pinching the support mechanism 5 by both protrusion part 41A, 41B. In the present embodiment, the holding portion 41 is provided with a slit 41C extending along the central axis direction. The slit 41C allows the rear end side opening of the holding portion 41 to be easily opened when the support mechanism 5 is inserted into the holding portion 41 from the rear end side opening.

アーム部42は、保持部41のうち前記スリット41C間に位置する部位から径方向外側に向けて延び、周方向に沿って等間隔に複数(本実施形態では、4つ)設けられている。また、アーム部42は、保持部41の中心軸方向に沿って延びる板状をなす連結部43と、当該連結部43の先端部に設けられた湾曲状の湾曲部44とを備えている。   The arm portion 42 extends radially outward from a portion located between the slits 41 </ b> C in the holding portion 41, and a plurality (four in this embodiment) are provided at equal intervals along the circumferential direction. The arm portion 42 includes a connecting portion 43 having a plate shape extending along the central axis direction of the holding portion 41, and a curved bending portion 44 provided at the distal end portion of the connecting portion 43.

連結部43は、保持部41の中心軸方向に沿って保持部41の中間から保持部41の下端にかけて形成されており、アタッチメント部材4を排水口部材2の内周に配置したときに、自身の最外周部が、排水口部材2の内周面にほぼ接触するようになっている。従って、アタッチメント部材4を排水口部材2の内周に配置したときには、連結部43の存在により前記スリット41Cの拡幅が防止され、その結果、保持部41からの支持機構5の抜け防止が図られるようになっている。   The connecting portion 43 is formed from the middle of the holding portion 41 to the lower end of the holding portion 41 along the central axis direction of the holding portion 41, and when the attachment member 4 is arranged on the inner periphery of the drain port member 2, The outermost peripheral portion is substantially in contact with the inner peripheral surface of the drain port member 2. Therefore, when the attachment member 4 is arranged on the inner periphery of the drain port member 2, the presence of the connecting portion 43 prevents the slit 41C from being widened. As a result, the support mechanism 5 can be prevented from coming off from the holding portion 41. It is like that.

湾曲部44は、排水口部材2の内周面に沿った湾曲状をなし、径方向に沿った肉厚が、前記排水口部材2の凸部23の径方向内側に向けた突出量とほぼ等しくされている。また、湾曲部44は、その下方側に径方向外側に突出する爪部44Aを備えており、その上方側に下方側よりも幅広の幅広部44Bを備えている。そして、アタッチメント部材4は、リング部材3の段差部33に爪部44Aが係止されるとともに、リング部材3の肉厚部34に幅広部44Bが載置され、爪部44A及び幅広部44Bでリング部材3を挟み込むことにより、リング部材3に取付けられている。また、爪部44Aのうち段差部33に係止される面は、径方向外側に向かうにつれて下方側へと徐々に傾斜する形状となっており、湾曲部44の下端側外周面は、径方向外側に向かうにつれて上方側に徐々に傾斜する形状となっている。   The curved portion 44 has a curved shape along the inner peripheral surface of the drain port member 2, and the thickness along the radial direction is substantially the same as the protruding amount toward the radially inner side of the convex portion 23 of the drain port member 2. Are equal. Further, the bending portion 44 includes a claw portion 44A that protrudes radially outward on the lower side, and includes a wider portion 44B that is wider than the lower side on the upper side. The attachment member 4 has the claw portion 44A locked to the stepped portion 33 of the ring member 3, and the wide portion 44B is placed on the thick portion 34 of the ring member 3. The claw portion 44A and the wide portion 44B It is attached to the ring member 3 by sandwiching the ring member 3. Moreover, the surface latched by the level | step-difference part 33 among nail | claw parts 44A becomes a shape which inclines gradually below as it goes to radial direction outer side, and the lower end side outer peripheral surface of the curved part 44 is radial direction. The shape is gradually inclined upward as it goes outward.

ここで、アタッチメント部材4をリング部材3に取付ける際には、アタッチメント部材4をリング部材3に対してその上方側から接近させ、湾曲部44の下端側外周面(傾斜面)をリング部材3の内周面に接触させることで爪部44Bが径方向内側に弾性変形する。そして、この状態で、アタッチメント部材4をリング部材3にさらに挿入していき、爪部44Aが段差部33に到達すると、爪部44Aが弾性復帰し、段差部33に爪部44Aが係止され、リング部材3にアタッチメント部材4が取付けられる。一方で、アタッチメント部材4をリング部材3から取外す際には、爪部44Aのうち段差部33に係止される面が傾斜面とされていることから、アタッチメント部材4に対して上方側に向けた力を加えることで、爪部44Aが径方向内側に向けて弾性変形し(つまり、段差部33に対する爪部44Aの係止力が解除され)、アタッチメント部材4がリング部材3から取外される。すなわち、本実施形態によれば、アタッチメント部材4(アーム部42)が、リング部材3に対して容易に取付・取外可能とされている。   Here, when attaching the attachment member 4 to the ring member 3, the attachment member 4 is made to approach the ring member 3 from the upper side thereof, and the lower end side outer peripheral surface (inclined surface) of the curved portion 44 is set to the ring member 3. The claw portion 44B is elastically deformed radially inward by being brought into contact with the inner peripheral surface. In this state, the attachment member 4 is further inserted into the ring member 3, and when the claw portion 44A reaches the stepped portion 33, the claw portion 44A is elastically restored, and the claw portion 44A is locked to the stepped portion 33. The attachment member 4 is attached to the ring member 3. On the other hand, when the attachment member 4 is removed from the ring member 3, the surface of the claw portion 44 </ b> A that is locked to the stepped portion 33 is an inclined surface, so that it faces upward with respect to the attachment member 4. As a result, the claw portion 44A is elastically deformed radially inward (that is, the locking force of the claw portion 44A with respect to the step portion 33 is released), and the attachment member 4 is removed from the ring member 3. The That is, according to the present embodiment, the attachment member 4 (arm portion 42) can be easily attached to and detached from the ring member 3.

さらに、アタッチメント部材4が取付けられたリング部材3の上面部に対して、排水口部材2の下面部を接触させた状態では、前記湾曲部44(幅広部44B)同士の間に前記凸部23が配置されるとともに、湾曲部44の側面が凸部23の側面に対してほぼ接触するように構成されている。すなわち、図6(図6では栓蓋6を不図示)に示すように、湾曲部44及び凸部23が環状に連なるように構成されている。また、上述の通り、湾曲部44の肉厚と、凸部23の径方向内側に向けた突出量とはほぼ等しくされているため、湾曲部44の内面及び凸部23の内面は面一となっている。   Further, in a state where the lower surface portion of the drain port member 2 is brought into contact with the upper surface portion of the ring member 3 to which the attachment member 4 is attached, the convex portion 23 is interposed between the curved portions 44 (wide portions 44B). Is arranged, and the side surface of the curved portion 44 is configured to substantially contact the side surface of the convex portion 23. That is, as shown in FIG. 6 (the stopper lid 6 is not shown in FIG. 6), the bending portion 44 and the convex portion 23 are configured to be connected in an annular shape. Further, as described above, since the thickness of the curved portion 44 and the protruding amount toward the radially inner side of the convex portion 23 are substantially equal, the inner surface of the curved portion 44 and the inner surface of the convex portion 23 are flush with each other. It has become.

図1に戻り、前記支持機構5は、前記保持部41に対して上下方向に相対移動可能な支持軸51と、押しボタン等により構成された操作部(図示せず)の変位を前記支持軸51に伝達するための伝達部52(例えば、金属製のワイヤー)とを備えている。支持軸51は、その先端部が栓蓋6の背面に形成された筒状部位に嵌着されており、支持軸51により栓蓋6は上下動可能に支持されている。伝達部52は、その外周に設けられた筒状のチューブ53内を移動可能に構成されており、前記操作部の変位によりチューブ53内を移動するようになっている。本実施形態では、前記操作部の操作に伴い、伝達部52を介して上昇端における支持軸51のロックと、ロック解除に伴う支持軸51の下降とが交互に行われるようになっている。すなわち、前記操作部を操作する度に栓蓋6の上昇・下降(排水口101の開閉)が交互に行われるようになっている。   Returning to FIG. 1, the support mechanism 5 moves the support shaft 51 by displacing an operation portion (not shown) configured by a support shaft 51 that can move in the vertical direction relative to the holding portion 41 and a push button. A transmission unit 52 (for example, a metal wire). The support shaft 51 is fitted into a cylindrical portion formed on the back surface of the plug lid 6 at the tip, and the plug lid 6 is supported by the support shaft 51 so as to be movable up and down. The transmission part 52 is configured to be movable in a cylindrical tube 53 provided on the outer periphery thereof, and moves in the tube 53 by the displacement of the operation part. In the present embodiment, with the operation of the operation unit, the support shaft 51 is locked at the rising end and the support shaft 51 is lowered when the lock is released via the transmission unit 52. That is, every time the operation unit is operated, the stopper lid 6 is alternately raised and lowered (opening / closing the drain port 101).

栓蓋6は、POM等の樹脂からなる蓋部61と、弾性変形可能な素材(例えば、樹脂やEPDMゴム等)からなる環状のパッキン62とを備えている。前記蓋部61は、表面がなだらかに湾曲する傘状部61Aと、当該傘条部61Aの背面内側から下方に向けて延びる筒状の突状部61Bとを備えており、突状部61Bの外周に設けられた凹部に前記パッキン62が嵌合されている。加えて、前記パッキン62は、外周側に向けて徐々に薄くなるように構成されており、排水口101の閉時には、その外周部分の全周が浴槽100に対して接触するようになっている。   The plug lid 6 includes a lid portion 61 made of a resin such as POM and an annular packing 62 made of an elastically deformable material (for example, resin or EPDM rubber). The lid portion 61 includes an umbrella-shaped portion 61A whose surface is gently curved, and a cylindrical protruding portion 61B extending downward from the inner side of the back surface of the umbrella-shaped portion 61A. The packing 62 is fitted in a recess provided on the outer periphery. In addition, the packing 62 is configured to be gradually thinner toward the outer peripheral side, and when the drain port 101 is closed, the entire outer periphery of the packing 62 comes into contact with the bathtub 100. .

次いで、上述した排水栓装置1の浴槽100に対する配設手順について説明する。   Subsequently, the arrangement | positioning procedure with respect to the bathtub 100 of the drain plug apparatus 1 mentioned above is demonstrated.

図7に示すように、まず、少なくとも上方部分(被係止部32の形成された部分)が配管102の上端側開口よりも上方側に位置するようにして(すなわち、排水口部材2を配管102に螺合することなく、排水口部材2の下面部をリング部材3の上面部に接触可能となるようにして)リング部材3を配管102に螺合しておくとともに、保持部41に支持機構5が挿設されたアタッチメント部材4を前記リング部材3に予め取付けておく。尚、配管102に対するリング部材3や支持機構5等の取付は、例えば、工場など、浴槽100の設置場所以外の場所で行うことができる。   As shown in FIG. 7, first, at least the upper portion (the portion where the locked portion 32 is formed) is positioned above the upper end side opening of the pipe 102 (that is, the drain port member 2 is connected to the pipe). The ring member 3 is screwed to the pipe 102 and supported by the holding portion 41 (with the lower surface portion of the drain port member 2 being brought into contact with the upper surface portion of the ring member 3 without being screwed to 102). The attachment member 4 in which the mechanism 5 is inserted is attached to the ring member 3 in advance. In addition, attachment of the ring member 3, the support mechanism 5, etc. with respect to the piping 102 can be performed in places other than the installation place of the bathtub 100, such as a factory, for example.

次いで、図8に示すように、リング部材3やアタッチメント部材4等が取付けられた配管102を、排水口101の背面側において、シール部材7を介して浴槽100に接触させる。そして、リング部材3上に排水口部材2を載置し、係止部24を被係止部32に係止するとともに、排水口部材2の下面部をリング部材3の上面部に接触させる。次に、所定の取付用治具(図示せず)を前記排水口部材2の凸部23に係止させた上で、排水口部材2の張出部21と配管102との間で浴槽100の鍔部102Aを挟み込むまで、浴槽100の表面側から排水口部材2を配管102にねじ込む。これにより、排水口部材2及びリング部材3が配管102に対して同時に螺合される。尚、上述の通り、被係止部32に対する係止部24の係止代の高さXは、第1雄ねじ部22のねじピッチよりも小さくされているため、排水口部材2の下面部がリング部材3の上面部に接触していない限り、被係止部32に係止部24を係止しつつ、排水口部材2及びリング部材3を配管102に対して同時に螺合することはできない。つまり、被係止部32に係止部24を係止しつつ、排水口部材2及びリング部材3を同時に配管102に螺合できたということは、排水口部材2の下面部にリング部材3の上面部が接触していることとなる。従って、配管102に螺合されたリング部材3は、排水口部材2の下面部を基準とする適切な配置位置に設けられ、ひいては、リング部材3に取付けられたアタッチメント部材4及び当該アタッチメント部材4に保持された支持機構5も適切な配置位置に設けられることとなる。   Next, as shown in FIG. 8, the pipe 102 to which the ring member 3, the attachment member 4, and the like are attached is brought into contact with the bathtub 100 via the seal member 7 on the back side of the drain port 101. Then, the drain port member 2 is placed on the ring member 3, the locking portion 24 is locked to the locked portion 32, and the lower surface portion of the drain port member 2 is brought into contact with the upper surface portion of the ring member 3. Next, after a predetermined mounting jig (not shown) is locked to the convex portion 23 of the drain port member 2, the bathtub 100 is provided between the protruding portion 21 of the drain port member 2 and the pipe 102. The drain port member 2 is screwed into the pipe 102 from the surface side of the bathtub 100 until the flange portion 102A is sandwiched. Thereby, the drain port member 2 and the ring member 3 are simultaneously screwed into the pipe 102. As described above, the height X of the locking allowance of the locking portion 24 with respect to the locked portion 32 is made smaller than the screw pitch of the first male screw portion 22, so that the lower surface portion of the drain port member 2 is The drain port member 2 and the ring member 3 cannot be screwed to the pipe 102 at the same time while locking the locking portion 24 to the locked portion 32 unless the upper surface portion of the ring member 3 is in contact. . That is, the fact that the drain port member 2 and the ring member 3 can be simultaneously screwed into the pipe 102 while locking the locking portion 24 to the locked portion 32 means that the ring member 3 is connected to the lower surface portion of the drain port member 2. The upper surface part of is in contact. Therefore, the ring member 3 screwed into the pipe 102 is provided at an appropriate arrangement position with respect to the lower surface portion of the drain port member 2, and as a result, the attachment member 4 attached to the ring member 3 and the attachment member 4 The support mechanism 5 held in the position is also provided at an appropriate arrangement position.

排水口部材2等の取付後、図9に示すように、支持機構5の先端部に栓蓋6を固定することで、浴槽100に対する排水栓装置1の配設が完了することとなる。   After mounting the drain port member 2 and the like, as shown in FIG. 9, the stopper lid 6 is fixed to the distal end portion of the support mechanism 5, whereby the arrangement of the drain plug device 1 with respect to the bathtub 100 is completed.

尚、図10に示すように、排水栓装置1の取付後であっても、排水口部材2の上方からアタッチメント部材4を引き抜くことで、排水口部材2を取外すことなく、アタッチメント部材4やこれに保持された支持機構5を取外すことが可能である。   As shown in FIG. 10, even after the drain plug device 1 is attached, the attachment member 4 or the like can be removed without removing the drain port member 2 by pulling out the attachment member 4 from above the drain port member 2. It is possible to remove the support mechanism 5 held in the box.

以上詳述したように、本実施形態によれば、支持機構5を保持するアタッチメント部材4が取付けられたリング部材3を、配管102に予め螺合しておくことで、配管102に対して支持機構5を予め取付けておくことができる。このため、配管102内から支持機構5を引き出すといった面倒な作業が不要となり、取付作業性の向上や支持機構5の引き出し時における部材(例えば、伝達部52や配管102など)の破損防止を図ることができる。   As described above in detail, according to the present embodiment, the ring member 3 to which the attachment member 4 that holds the support mechanism 5 is attached is screwed into the pipe 102 in advance, thereby supporting the pipe 102. The mechanism 5 can be attached in advance. For this reason, the troublesome work of pulling out the support mechanism 5 from the inside of the pipe 102 becomes unnecessary, and improvement of mounting workability and prevention of breakage of members (for example, the transmission unit 52 and the pipe 102) when the support mechanism 5 is pulled out are achieved. be able to.

さらに、第1雄ねじ部22のねじピッチ、及び、第2雄ねじ部31のねじピッチが等しくされるとともに、係止部24を被係止部32に係止し、かつ、リング部材3の上面部に排水口部材2の下面部を接触させた状態において、第1雄ねじ部22のねじ山に対して第2雄ねじ部31のねじ山が連続する螺旋状とされている。従って、配管102に対してリング部材3をその最終的な配置位置よりも手前側に螺合した状態において、被係止部32に対して係止部24を係止し排水口部材2に対するリング部材3の相対回転を規制した上で、配管102に対して排水口部材2を相対回転させることにより、排水口部材2とともにリング部材3を配管に螺合することができる。そして、排水口部材2を最終的な配置位置に設けたときに、リング部材3は、排水口部材2の下面部を基準とする適切な配置位置に設けられ、ひいては栓蓋6の開口量(ストローク量)を安定させることができる。   Further, the screw pitch of the first male screw portion 22 and the screw pitch of the second male screw portion 31 are equalized, the locking portion 24 is locked to the locked portion 32, and the upper surface portion of the ring member 3 In the state where the lower surface portion of the drain port member 2 is in contact with the screw port, the screw thread of the second male screw part 31 is continuous with the screw thread of the first male screw part 22. Therefore, in a state where the ring member 3 is screwed to the pipe 102 closer to the front side than the final arrangement position, the locking portion 24 is locked to the locked portion 32 and the ring to the drain port member 2 is locked. By restricting relative rotation of the member 3 and rotating the drain port member 2 relative to the pipe 102, the ring member 3 can be screwed into the pipe together with the drain port member 2. When the drain port member 2 is provided at the final arrangement position, the ring member 3 is provided at an appropriate arrangement position with respect to the lower surface portion of the drain port member 2, and as a result, the opening amount of the plug lid 6 ( Stroke amount) can be stabilized.

すなわち、本実施形態のように、栓蓋6が浴槽100に密着することで排水口101を閉鎖する場合、排水口部材2は、配管102との間で浴槽100を挟み込む際に浴槽100の表面に接触するが、浴槽100の表面は裏面等と比較して通常精度よく形成される。そのため、同種の浴槽100において、栓蓋6によるシール位置から、排水口部材2が接触する表面までの距離にバラツキが生じてしまうことが極めて少ない。従って、排水口部材2を最終的な配置位置に設けたときに、排水口部材2は栓蓋によるシール位置に対して一定の位置に設けられ、ひいては排水口部材2の下面部に接触するリング部材3、及び、これに取付けられる支持機構5の配置位置も前記シール位置に対して一定の位置に設けられる。その結果、栓蓋6の開口量(ストローク量)が安定することとなる。このように本実施形態によれば、排水口部材2を最終的な配置位置に設けたときに、リング部材3は適切な位置に配置されるため、排水口部材2の取付後に、リング部材3を移動させる必要はない。従って、排水栓装置1の取付作業性を一層向上させることができる。   That is, when the drain lid 101 is closed by the stopper lid 6 being in close contact with the bathtub 100 as in the present embodiment, the drain port member 2 has a surface of the bathtub 100 when sandwiching the bathtub 100 with the pipe 102. However, the surface of the bathtub 100 is usually formed with higher accuracy than the back surface or the like. Therefore, in the same kind of bathtub 100, the distance from the sealing position by the plug lid 6 to the surface to which the drain port member 2 contacts is extremely small. Therefore, when the drain port member 2 is provided at the final arrangement position, the drain port member 2 is provided at a fixed position with respect to the sealing position by the plug lid, and as a result, a ring that contacts the lower surface portion of the drain port member 2. The arrangement position of the member 3 and the support mechanism 5 attached thereto is also provided at a fixed position with respect to the seal position. As a result, the opening amount (stroke amount) of the plug lid 6 is stabilized. As described above, according to the present embodiment, when the drain port member 2 is provided at the final arrangement position, the ring member 3 is disposed at an appropriate position. There is no need to move. Therefore, the workability of mounting the drain plug device 1 can be further improved.

加えて、本実施形態では、アタッチメント部材4のアーム部42が、排水口部材2の上方からリング部材3に対して取付・取外可能とされている。従って、リング部材3からアーム部42(アタッチメント部材4)を取外すことで、排水口部材2を配管102から取外すことなく、アタッチメント部材4ひいては支持機構5を容易に取外すことができる。その結果、メンテナンス性の向上を図ることができる。   In addition, in this embodiment, the arm portion 42 of the attachment member 4 can be attached to and detached from the ring member 3 from above the drain port member 2. Therefore, by removing the arm portion 42 (attachment member 4) from the ring member 3, the attachment member 4 and thus the support mechanism 5 can be easily removed without removing the drain port member 2 from the pipe 102. As a result, maintenance can be improved.

また、本実施形態では、被係止部32に対する係止部24の係止代の高さXが、第1雄ねじ部22のねじピッチよりも小さくされている。従って、リング部材3が所定の位置よりもねじピッチ分だけ下方側に配置されてしまうという事態をより確実に防止することができる。その結果、リング部材3ひいては支持機構5を所定の位置に対してより確実に配置することができる。   In the present embodiment, the height X of the locking margin of the locking portion 24 with respect to the locked portion 32 is made smaller than the screw pitch of the first male screw portion 22. Therefore, the situation where the ring member 3 is disposed below the predetermined position by the screw pitch can be more reliably prevented. As a result, the ring member 3 and thus the support mechanism 5 can be more reliably arranged with respect to a predetermined position.

In addition, the inner surface of the curved portion 44 and the inner surface of the convex portion 23 are configured to be flush with each other when the lower surface portion of the drain port member 2 is in contact with the upper surface portion of the ring member 3. Therefore, the appearance quality can be improved, the water flow area can be further increased, and the drainage capacity can be further enhanced.
[Second Embodiment]
Next, the second embodiment will be described focusing on differences from the first embodiment. As shown in FIG. 11, the drain plug device 1 </ b> A according to the second embodiment includes a drain port member 2 and a ring member 3, as in the first embodiment. Although the external thread part 25 which can be screwed together in the internal thread part 102A is provided, unlike the said 1st Embodiment, the outer peripheral surface of the ring member 3 is made into the smooth shape. In the second embodiment, the lower surface portion of the drain port member 2 and the upper surface portion of the ring member 3 are flat (that is, the locking portion 24 and the locked portion 32 are not provided). In addition, an elastic member 8 made of a spring is provided below the ring member 3.

弾性部材8は、配管102の内周に設けられた段部102Bとリング部材3との間に配置されており、上端部がリング部材3の下面部に接触し、下端部が段部102Bに接触している。また、弾性部材8は、リング部材3に対して排水口部材2側に向けた力を付勢しており、その結果、リング部材3の上面部は、排水口部材2の下面部に接触している。   The elastic member 8 is disposed between a step 102B provided on the inner periphery of the pipe 102 and the ring member 3, and the upper end contacts the lower surface of the ring member 3 and the lower end of the step 102B. In contact. Further, the elastic member 8 urges the ring member 3 toward the drain port member 2 side. As a result, the upper surface portion of the ring member 3 contacts the lower surface portion of the drain port member 2. ing.

次いで、上述した排水栓装置1Aの浴槽100に対する配設手順について説明する。   Subsequently, the arrangement | positioning procedure with respect to the bathtub 100 of the drain plug apparatus 1A mentioned above is demonstrated.

まず、工場等において、配管102内にリング部材3及び弾性部材8を予め設けておくとともに、支持機構5が挿設されたアタッチメント部材4を、リング部材3に予め取付けておく。次いで、リング部材3等が取付けられた配管102を、排水口101の背面側において、シール部材7を介して浴槽100に接触させる。そして、所定の取付用治具を排水口部材2の凸部23に係止させた上で、配管102に対して排水口部材2をねじ込み、排水口部材2を最終的な配置位置に取付ける。尚、排水口部材2を最終的な配置位置に取付けた状態において、弾性部材8からの付勢力により、リング部材3は、自身の上面部が排水口部材2の下面部に押し付けられた状態となっている。そのため、リング部材3は、排水口部材2の下面部を基準とする適切な配置位置に設けられることとなり、ひいてはアタッチメント部材4及びこれに保持される支持機構5も適切な配置位置に設けられることとなる。   First, in a factory or the like, the ring member 3 and the elastic member 8 are provided in advance in the pipe 102, and the attachment member 4 into which the support mechanism 5 is inserted is attached to the ring member 3 in advance. Next, the pipe 102 to which the ring member 3 and the like are attached is brought into contact with the bathtub 100 via the seal member 7 on the back side of the drain port 101. Then, after a predetermined mounting jig is locked to the convex portion 23 of the drain port member 2, the drain port member 2 is screwed into the pipe 102, and the drain port member 2 is mounted at the final arrangement position. In the state where the drain port member 2 is attached to the final arrangement position, the ring member 3 has its upper surface pressed against the lower surface of the drain port member 2 by the urging force from the elastic member 8. It has become. Therefore, the ring member 3 is provided at an appropriate arrangement position with reference to the lower surface portion of the drain port member 2, and the attachment member 4 and the support mechanism 5 held by the attachment member 4 are also provided at an appropriate arrangement position.

Further, when the drain port member 2 is screwed, it is not necessary to lock the locking portion 24 with respect to the locked portion 32, and as a result, the male screw portions 22 and 31 have a continuous spiral shape. The troublesome work of selecting the locked portion 32 to which the locking portion 24 is locked cannot occur. Therefore, the mounting workability can be further improved. In addition, when the widths of the respective locking portions 24 are equal, it is particularly troublesome to select an appropriate locked portion 32. However, as in the first embodiment, When the width is different and the relative position between the two is uniquely determined when the drain member 2 is combined with the ring member 3, the appropriate locked portion 32 can be easily selected, which is very troublesome. It ’s not work.
