Description

本発明は、槽体の排水口を開閉するための排水栓装置に関する。   The present invention relates to a drain plug device for opening and closing a drain outlet of a tank body.

排水栓装置は、槽体(浴槽や洗面器など)に設けられた排水口を開閉するための栓蓋を備えており、近年では、遠隔操作により栓蓋を上下動させ、排水口を開閉させる技術が知られている。   The drain plug device is provided with a plug lid for opening and closing a drain outlet provided in a tank body (tub, basin, etc.). In recent years, the drain lid is moved up and down by remote control to open and close the drain outlet. Technology is known.

このような排水栓装置としては、押しボタンなどの軸方向に沿って変位する可動部材と、栓蓋を支持する支持軸及び前記可動部材の間を連結し、前記可動部材の軸方向に沿った変位を支持軸へと伝達する伝達部材とを備えるものが提案されている。ここで、前記支持軸は、通水性や栓蓋によるシール性の面を鑑みて、排水口の中心軸上に設けられるのが一般的であり、前記伝達部材は、前記支持軸の下端部に対して連結される(例えば、特許文献1等参照)。   As such a drain plug device, a movable member that is displaced along an axial direction such as a push button, a support shaft that supports a plug lid, and the movable member are connected to each other along the axial direction of the movable member. A thing provided with the transmission member which transmits displacement to a support axis is proposed. Here, the support shaft is generally provided on the central axis of the drain port in view of water permeability and sealing performance by the plug lid, and the transmission member is provided at the lower end of the support shaft. They are connected to each other (see, for example, Patent Document 1).

特開平11−21965号公報Japanese Patent Laid-Open No. 11-21965

ところで、支持軸が排水口の中心軸上に位置することから、伝達部材を支持軸に連結するためには、伝達部材の端部を排水口の中心軸(換言すれば、配管の中心)にまで到達させることが必要である。しかしながら、この場合には、配管に対して伝達部材が比較的大きく突出した状態となるため、伝達部材に対して毛髪やゴミ等が引っ掛かりやすくなってしまい、ひいては配管の詰まりが生じやすくなってしまうおそれがある。また、伝達部材の存在により、その下方に位置する配管やトラップ等の清掃に支障が生じてしまうおそれがある。   By the way, since the support shaft is located on the central axis of the drain outlet, in order to connect the transmission member to the support shaft, the end of the transmission member is connected to the central axis of the drain outlet (in other words, the center of the pipe). It is necessary to reach up to. However, in this case, since the transmission member protrudes relatively large from the pipe, hair, dust, etc. are likely to be caught on the transmission member, and the pipe is likely to be clogged. There is a fear. Moreover, there exists a possibility that trouble may arise in cleaning of piping, a trap, etc. which are located in the downward direction by presence of a transmission member.

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、伝達部材の存在に起因する配管の詰まり等の不具合をより確実に防止することができる排水栓装置を提供することにある。   This invention is made in view of the said situation, The objective is to provide the drain plug apparatus which can prevent more reliably malfunctions, such as clogging of piping resulting from presence of a transmission member. .

Means 1. A plug lid provided at the drain of the tank body;
A support shaft that supports the stopper lid at one end of itself;
While having an annular outer peripheral wall disposed along the inner peripheral surface of the pipe in the drainage pipe, a water passage member that supports the other end of the support shaft;
An operation unit that is attached to the tank body or a structure in the vicinity thereof and has a movable member that can be displaced with respect to the tank body or the structure;
A drain plug device provided between the movable member and the support shaft, and a transmission member that transmits the displacement of the movable member to the support shaft side;
While having a support protrusion protruding into the pipe from one end of the transmission member,
The outer peripheral wall of the water flow member is supported by the support protrusion,
A portion of the support protrusion that supports at least the water passage member is configured to be vertically movable with respect to the tank body by displacement of the movable member,
The tip of the support protrusion does not reach the center of the pipe ,
The water flow member is configured so that a lower end surface of an outer peripheral wall thereof is placed on the support protrusion, so that the water flow member is supported in the pipe and is removable from the pipe. Drain plug device to do.

上記手段1によれば、支持軸を支持する通水部材のうち、その外周壁が支持突起に支持され、支持突起の先端は配管の中心に到達しないように構成されている。つまり、配管の内周面に対する支持突起の突出量が非常に小さなものとされている。従って、支持突起に対して毛髪やゴミ等が極めて引っ掛かりにくくなり、配管の詰まりを効果的に抑制することができる。また、支持突起から先(下方)に位置する配管やトラップ等を比較的容易に清掃することができる。
さらに、通水部材は、その外周壁が支持突起に載置状態とされることで、配管内にて支持されている。そのため、配管に対する通水部材の着脱をより容易に行うことができ、通水部材から先の配管等の清掃をより一層容易に行うことができる。
According to the said means 1, the outer peripheral wall is supported by the support protrusion among the water flow members which support a support shaft, and the front-end | tip of a support protrusion is comprised so that it may not reach the center of piping. That is, the protruding amount of the support protrusion with respect to the inner peripheral surface of the pipe is very small. Accordingly, hair, dust and the like are hardly caught on the support protrusion, and clogging of the pipe can be effectively suppressed. In addition, pipes, traps, and the like located ahead (downward) from the support protrusion can be cleaned relatively easily.
Furthermore, the water flow member is supported in the pipe by placing the outer peripheral wall on the support protrusion. Therefore, attachment / detachment of the water passage member to / from the pipe can be performed more easily, and cleaning of the pipe and the like from the water passage member can be performed more easily.

手段2.前記可動部材は、自身の中心軸を回転軸として前記槽体又は前記構造物に対して相対回転可能に構成されるとともに、
前記伝達部材は、自身の中心軸を回転軸として回転することで前記可動部材の回転変位を伝達し、かつ、自身の一端部が、前記支持軸の中心軸と交差する方向に延び、
前記支持突起は、前記可動部材の回転により前記伝達部材の一端部の中心軸を回転軸として回転可能に構成され、自身の回転に伴い前記槽体に対して上下動することを特徴とする手段1に記載の排水栓装置。
Mean 2. The movable member is configured to be relatively rotatable with respect to the tank body or the structure with its own central axis as a rotation axis.
The transmission member transmits the rotational displacement of the movable member by rotating about its central axis as a rotation axis, and its one end extends in a direction intersecting the central axis of the support shaft,
The support protrusion is configured to be rotatable about the central axis of one end of the transmission member by the rotation of the movable member, and moves up and down with respect to the tank body with its rotation. The drain plug device according to 1.

押しボタン式などの軸方向に沿って変位する可動部材においては、その変位する範囲に対応するために、可動部材を支持する部材等を比較的長尺化する必要がある。そのため、操作部が比較的大型になってしまい、操作部を配設可能な位置は、槽体や構造物のうち内部に十分なスペースがある位置に限られてしまう。   In a movable member that is displaced along the axial direction, such as a push button type, it is necessary to make the member that supports the movable member relatively long in order to accommodate the displacement range. Therefore, an operation part becomes comparatively large and the position which can arrange | position an operation part will be restricted to a position with sufficient space inside a tank body or a structure.

この点、上記手段2によれば、可動部材は、自身の中心軸を回転軸として槽体等に対して相対回転可能に構成されている。そのため、可動部材を支持する部材等の長尺化等が不要となり、操作部の小型化を図ることができる。その結果、槽体等のうち内部スペースが比較的小さな位置であっても操作部を配設することができ、栓蓋や支持軸に対する操作部の相対位置関係を比較的自由に設定することができる。   In this regard, according to the means 2, the movable member is configured to be rotatable relative to the tank body or the like with its own central axis as the rotation axis. Therefore, it is not necessary to lengthen the member that supports the movable member, and the operation unit can be downsized. As a result, the operation unit can be disposed even if the internal space of the tank body is relatively small, and the relative positional relationship of the operation unit with respect to the plug lid and the support shaft can be set relatively freely. it can.

手段3.前記支持突起の一端側から見たとき、前記伝達部材の一端部の回転軸から鉛直上方に延びる直線上に前記支持突起と前記通水部材の外周壁との接触部分が配置されないように、前記支持突起の回転可能範囲が規制されることを特徴とする手段2に記載の排水栓装置。   Means 3. When viewed from one end side of the support protrusion, the contact portion between the support protrusion and the outer peripheral wall of the water passage member is not disposed on a straight line extending vertically upward from the rotation shaft of one end portion of the transmission member. The drain plug device according to the means 2, wherein the rotatable range of the support protrusion is restricted.

排水口が開いた状態において、支持突起の一端側から見て、伝達部材の一端部の回転軸から鉛直上方に延びる直線上に支持突起と通水部材の外周壁との接触部分が位置していると、栓蓋が踏まれること等により通水部材に上方から大きな力が加わってしまったときに、支持突起に対してその大きな力が直接加わってしまう。その結果、支持突起に破損が生じてしまうおそれがある。   When the drainage port is open, the contact portion between the support protrusion and the outer peripheral wall of the water passage member is positioned on a straight line extending vertically upward from the rotation axis of one end of the transmission member when viewed from one end side of the support protrusion. When the cap lid is stepped on, when a large force is applied to the water passage member from above, the large force is directly applied to the support protrusion. As a result, the support protrusion may be damaged.

この点、上記手段3によれば、通水部材に上方から大きな力が加わった際に、支持突起が回転することとなり、ひいては支持突起に加わる力を低減させることができる。これにより、支持突起の破損をより確実に防止することができる。   In this respect, according to the means 3, the support protrusion rotates when a large force is applied to the water passage member from above, and as a result, the force applied to the support protrusion can be reduced. Thereby, breakage of the support protrusion can be prevented more reliably.

手段4.前記操作部は、前記可動部材の回転を規制する回転規制機構を備え、前記可動部材の回転を規制することで、前記支持突起の回転可能範囲が規制されることを特徴とする手段3に記載の排水栓装置。   Means 4. The operation unit includes a rotation restricting mechanism that restricts the rotation of the movable member, and the rotation range of the support protrusion is restricted by restricting the rotation of the movable member. Drain plug device.

支持突起の回転可能範囲を規制するにあたっては、例えば、伝達部材の一端部に、当該伝達部材の一端部の回転可能範囲を規制する手段を設けることが考えられる。ところが、この場合には、伝達部材の一端部の回転が規制された状態で可動部材が回転させられることで、伝達部材に対して比較的大きなねじり応力が加わってしまうおそれがあり、伝達部材における破損や変形等が懸念される。   In restricting the rotatable range of the support protrusion, for example, a means for restricting the rotatable range of the one end portion of the transmission member may be provided at one end portion of the transmission member. However, in this case, a relatively large torsional stress may be applied to the transmission member by rotating the movable member in a state where the rotation of one end of the transmission member is restricted. There are concerns about damage and deformation.

この点、上記手段4によれば、可動部材の回転を規制する回転規制機構により支持突起の回転可能範囲が規制されている。従って、伝達部材に対して大きなねじり応力が加わってしまうことを防止でき、伝達部材の破損等をより確実に防止することができる。   In this regard, according to the means 4, the rotatable range of the support protrusion is restricted by the rotation restricting mechanism that restricts the rotation of the movable member. Therefore, it can prevent that a big torsional stress is added with respect to a transmission member, and can prevent the failure | damage of a transmission member, etc. more reliably.

手段5.前記伝達部材の一端部は、前記支持軸の中心軸と交差する方向に延びるとともに、前記配管に対して接離移動可能とされ、前記配管に対する前記支持突起の突出量を変更可能であり、
前記支持突起は、前記配管側に向けて下方に傾斜する傾斜面を備え、前記傾斜面により前記通水部材の外周壁が支持されており、
前記配管に対して前記伝達部材の一端部を接離移動させることで、前記通水部材を前記槽体に対して上下動させることを特徴とする手段1に記載の排水栓装置。
Means 5. One end of the transmission member extends in a direction intersecting with the central axis of the support shaft, is movable toward and away from the pipe, and can change the protrusion amount of the support protrusion with respect to the pipe.
The support protrusion includes an inclined surface inclined downward toward the pipe side, and an outer peripheral wall of the water passage member is supported by the inclined surface,
The drain plug device according to claim 1, wherein the water passing member is moved up and down with respect to the tank body by moving one end of the transmission member toward and away from the pipe.

上記手段5によれば、基本的には上記手段1と同様の作用効果が奏されることとなる。加えて、通水部材に上方から大きな力が加わった際には、支持突起が配管の中心から離間する方向へと移動することとなる。そのため、支持突起の破損を防止するための特別な手段を設けることなく、支持突起の破損をより確実に防止することができる。   According to the means 5, basically the same effects as those of the means 1 are achieved. In addition, when a large force is applied to the water passage member from above, the support protrusion moves in a direction away from the center of the pipe. Therefore, the breakage of the support protrusion can be more reliably prevented without providing a special means for preventing the breakage of the support protrusion.

手段6.前記伝達部材の一端部は、前記配管に連通された筒状の取付管に挿通されており、
前記伝達部材の一端部は、斜め下方側に向けて延びていることを特徴とする手段1乃至5のいずれかに記載の排水栓装置。
Means 6. One end portion of the transmission member is inserted through a cylindrical mounting pipe communicated with the pipe,
The drain plug device according to any one of means 1 to 5, wherein one end of the transmission member extends obliquely downward.

上記手段6によれば、伝達部材の一端部が斜め下方側に延びているため、伝達部材の一端部と取付管との間を伝わった水の漏出をより確実に防止することができる。   According to the means 6, since the one end portion of the transmission member extends obliquely downward, the leakage of water transmitted between the one end portion of the transmission member and the attachment pipe can be prevented more reliably.

手段7.前記伝達部材の一端部は、前記配管に連通された筒状の取付管に挿通されるとともに、前記伝達部材の外周面には、凸状又は凹状をなす係合部が設けられており、
前記取付管に設けられ、前記係合部を係合可能な凹状又は凸状の被係合部に対して前記係合部が係合されていることを特徴とする手段1乃至6のいずれかに記載の排水栓装置。
Mean 7 One end portion of the transmission member is inserted into a cylindrical mounting pipe communicated with the pipe, and an outer peripheral surface of the transmission member is provided with a convex or concave engaging portion,
Any one of means 1 to 6, wherein the engaging portion is engaged with a concave or convex engaged portion that is provided on the attachment pipe and can engage the engaging portion. The drain plug device according to 1.

上記手段7によれば、取付管に対する伝達部材の配設を比較的容易に行うことができ、槽体等に対する排水栓装置の組付作業性を一層向上させることができる。   According to the means 7, the transmission member can be relatively easily arranged on the attachment pipe, and the workability of assembling the drain plug device to the tank body or the like can be further improved.

手段8.前記栓蓋の下方にはヘアキャッチャーが設けられるとともに、
前記ヘアキャッチャーは、前記支持軸が挿通されることで当該支持軸を支持する筒状部を備え、
前記支持軸は、
前記支持軸の一端側に位置し、自身の一端部において前記栓蓋を支持する棒状の一端側支持軸と、

前記一端側支持軸及び前記他端側支持軸は分離可能に構成されるとともに、
前記一端側支持軸、及び、前記他端側支持軸の一端部は、前記筒状部に挿通されており、
前記筒状部の内周面に設けられ、径方向内側に突出する爪部に対して、前記他端側支持軸の一端部の外周面に設けられ、径方向外側に突出する突部が着脱自在に係止可能とされていることを特徴とする手段1乃至7のいずれかに記載の排水栓装置。
Means 8. A hair catcher is provided below the stopper lid,
The hair catcher includes a cylindrical portion that supports the support shaft by inserting the support shaft,
The support shaft is
A rod-shaped one end side support shaft that is located on one end side of the support shaft and supports the stopper lid at one end of the support shaft;
A rod-shaped other end side support shaft which is located on the other end side of the support shaft and is arranged in series with respect to the one end side support portion and whose other end portion is fixed to the water passage member. Prepared,
The one end side support shaft and the other end side support shaft are configured to be separable,
The one end side support shaft and the one end portion of the other end side support shaft are inserted through the cylindrical portion,
A protrusion provided on the outer peripheral surface of one end of the other end side support shaft and protruding radially outward is attached to and detached from a claw provided on the inner peripheral surface of the cylindrical portion and protruding radially inward. The drain plug device according to any one of means 1 to 7, wherein the drain plug device is freely lockable.

上記手段8によれば、支持軸がヘアキャッチャーにより支持されるため、支持軸を支持するための部材を別途設ける必要がなく、部品点数の低減や構成の簡素化を図ることができる。その結果、製造コストを低減させることができる。   According to the means 8, since the support shaft is supported by the hair catcher, it is not necessary to separately provide a member for supporting the support shaft, and the number of parts can be reduced and the configuration can be simplified. As a result, the manufacturing cost can be reduced.

また、支持軸は、一端側支持軸と他端側支持軸とで分離可能に構成されるため、栓蓋を支持する一端側支持軸を筒状部から取外すことで、ヘアキャッチャーを排水口に配置したままの状態で、栓蓋を取外すことができる。これにより、ヘアキャッチャーを排水口に配置したまま、ヘアキャッチャーの上面を清掃するといったことが可能となる。   In addition, since the support shaft is configured to be separable between the one end side support shaft and the other end side support shaft, by removing the one end side support shaft that supports the plug lid from the cylindrical portion, the hair catcher can be used as a drain outlet. The plug lid can be removed in the state in which it is placed. Thereby, it becomes possible to clean the upper surface of the hair catcher while the hair catcher is disposed at the drain outlet.

さらに、他端側支持部の突部が筒状部の爪部に係止可能とされているため、ヘアキャッチャーを排水口から取外すことで、通水部材も取外すことができる。その結果、配管に対する通水部材の着脱をより容易に行うことができ、通水部材から先の配管等の清掃をより一層容易に行うことができる。加えて、爪部に対して突部が着脱自在であるため、筒状部(ヘアキャッチャー)から他端側支持軸ひいては通水部材を取外すことができ、ヘアキャッチャーや通水部材をそれぞれ単独で清掃することが可能となる。   Furthermore, since the protrusion part of the other end side support part can be latched to the nail | claw part of a cylindrical part, a water flow member can also be removed by removing a hair catcher from a drain outlet. As a result, it is possible to more easily attach and detach the water passage member to the pipe, and it is possible to more easily clean the pipe and the like from the water passage member. In addition, since the protrusion is detachable with respect to the claw part, the support shaft on the other end side and thus the water passage member can be removed from the tubular part (hair catcher), and the hair catcher and the water passage member can be removed individually. It becomes possible to clean.

A male screw portion 23 is formed on the outer peripheral surface of one end portion of the guide portion 21, and a predetermined nut 24 is inserted into the male screw portion 23 so as to sandwich the flange portion 102 between the other end portion of the guide portion 21. As a result, the guide portion 21 is fixed to the flange portion 102. A plurality of annular groove portions 25 extending in the circumferential direction are provided on the outer peripheral surface of the other end portion of the guide portion 21, and bulge outward on one end side (lower side) from the annular groove portion 25. A bowl-shaped portion 26 is provided. In addition, an annular seal member 27 is provided between the lower surface of the bowl-shaped portion 26 and the flange portion 102. The seal member 27 seals between the guide portion 21 and the flange portion 102.

In addition, an annular space portion 29 extending in the circumferential direction is formed between the outer peripheral surface of the guide portion 21 and the inner peripheral surface of the movable member 22 by the annular groove portion 25 provided in the guide portion 21. ing. Due to the presence of the space portion 29, it is possible to suppress the intrusion of water into the washbasin 100 transmitted between the guide portion 21 and the movable member 22, and further, the gap between the other end surface 21 </ b> F of the guide portion 21 and the movable member 22. By making surface contact along the circumferential direction, it is possible to further improve the water infiltration suppression effect.

さらに、図3(図3は、図2のA矢視透視図である)に示すように、前記操作部2は、前記可動部材22の回転を規制する回転規制機構2Aを備えている。回転規制機構2Aは、前記鍔状部26の上面に設けられた切欠部26Aと、可動部材22の内周面から突出し、前記切欠部26Aに差し込まれた突状部22Bとにより構成されている。切欠部26Aは、周方向に沿って延びるほぼ半周の溝であり、切欠部26Aの設けられた範囲内で突状部22Bが移動可能となっている。その結果、本実施形態では、可動部材22の回転可能範囲が約180度に規制されている。   Further, as shown in FIG. 3 (FIG. 3 is a perspective view as viewed in the direction of arrow A in FIG. 2), the operation unit 2 includes a rotation restricting mechanism 2 </ b> A that restricts the rotation of the movable member 22. The rotation restricting mechanism 2A includes a cutout portion 26A provided on the upper surface of the bowl-shaped portion 26, and a protrusion 22B protruding from the inner peripheral surface of the movable member 22 and inserted into the cutout portion 26A. . The cutout portion 26A is a substantially semicircular groove extending along the circumferential direction, and the protruding portion 22B can move within the range where the cutout portion 26A is provided. As a result, in the present embodiment, the rotatable range of the movable member 22 is restricted to about 180 degrees.

図1に戻り、前記伝達部材3は、樹脂材料により形成されるとともに、操作部2と排水口装置4との間に設けられ、可動部材22の回転変位を排水口装置4側へと伝達すべく、自身の中心軸を回転軸として回転可能に構成されている。伝達部材3は、操作部2から排水口装置4側に向かって、それぞれ棒状をなす第1伝達棒31と、第2伝達棒32と、第3伝達棒33とが直列的に接続されて構成されている。   Returning to FIG. 1, the transmission member 3 is formed of a resin material and is provided between the operation unit 2 and the drain port device 4, and transmits the rotational displacement of the movable member 22 to the drain port device 4 side. Therefore, it is configured to be rotatable about its own central axis as a rotation axis. The transmission member 3 is configured by connecting a first transmission rod 31, a second transmission rod 32, and a third transmission rod 33 each having a bar shape from the operation unit 2 toward the drain port device 4 side. Has been.

前記第1伝達棒31は、一端部が前記第2伝達棒32に連結される一方で、その他端部が前記ガイド部21に挿通されており、また、その他端部に爪状の係止部31Aを備えている。そして、可動部材22の一端部に設けられた突起状の被係止部22Aに対して第1伝達棒31の前記係止部31Aが係止されることで、可動部材22と伝達部材3との間がスナップフィット結合されており、可動部材22の回転変位が伝達部材3(第1棒状部31)に対して伝達されるようになっている。   One end of the first transmission rod 31 is connected to the second transmission rod 32, while the other end is inserted through the guide portion 21, and the other end is a claw-shaped locking portion. 31A is provided. Then, the locking member 31A of the first transmission rod 31 is locked to the protrusion-like locked portion 22A provided at one end of the movable member 22, so that the movable member 22, the transmission member 3, and the like The gap between them is snap-fit, and the rotational displacement of the movable member 22 is transmitted to the transmission member 3 (first rod-shaped portion 31).

前記第2伝達棒32は、メススプライン軸34にオススプライン軸35が挿通されてなるスライド機構36を備えており、当該スライド機構36により、第2伝達棒32ひいては伝達部材3が伸縮可能に構成されている。   The second transmission rod 32 is provided with a slide mechanism 36 in which a male spline shaft 35 is inserted into a female spline shaft 34, and the second transmission rod 32 and thus the transmission member 3 can be expanded and contracted by the slide mechanism 36. Has been.

加えて、前記第3伝達棒33は、その一端部が排水用の配管111に連通された筒状の取付管112に対して挿通されている。また、第3伝達棒33の外周面には凹状の係合部33Aが設けられており、当該係合部33Aに対して前記取付管112の端部に設けられた凸状の被係合部113が係合されている。その結果、第3伝達棒33は、自身の中心軸を回転軸として回転可能とされる一方で、その軸方向に沿った移動が規制されている。加えて、第3伝達棒33は、配管111に向かって斜め下方側に延びており、取付管112も配管111に向かって斜め下方側に延びている。また、第3伝達棒33の中心軸は、後述する支持軸42の中心軸(本実施形態では、鉛直方向)と交差する方向に延びている。   In addition, the third transmission rod 33 is inserted into a cylindrical attachment pipe 112 having one end portion thereof connected to the drainage pipe 111. Further, a concave engaging portion 33A is provided on the outer peripheral surface of the third transmission rod 33, and a convex engaged portion provided at the end of the mounting tube 112 with respect to the engaging portion 33A. 113 is engaged. As a result, the third transmission rod 33 is rotatable about its own central axis as a rotation axis, while movement along the axial direction is restricted. In addition, the third transmission rod 33 extends obliquely downward toward the pipe 111, and the attachment pipe 112 also extends obliquely downward toward the pipe 111. Further, the central axis of the third transmission rod 33 extends in a direction intersecting with a central axis (a vertical direction in the present embodiment) of a support shaft 42 described later.

さらに、前記第1伝達棒31と第2伝達棒32との間、及び、第2伝達棒32と第3伝達棒33との間は、それぞれユニバーサルジョイント37,38を介して連結されている。従って、第1、第2伝達棒31,32間の連結角度、及び、第2、第3伝達棒32,33間の連結角度を自在に変更することができ、ひいては可動部材22から伝達部材3の一端部(第3伝達棒33)に対する回転の伝達方向を変換できるようになっている。   Furthermore, the first transmission rod 31 and the second transmission rod 32 and the second transmission rod 32 and the third transmission rod 33 are connected via universal joints 37 and 38, respectively. Therefore, the connection angle between the first and second transmission rods 31 and 32 and the connection angle between the second and third transmission rods 32 and 33 can be freely changed. The direction of transmission of rotation with respect to one end portion (the third transmission rod 33) can be converted.

また、伝達部材3(第3伝達棒33)の一端面外周には、第3伝達棒33の中心軸方向に沿って延びる支持突起39が設けられており、前記可動部材22を回転させることで、第1伝達棒31、第2伝達棒32、第3伝達棒33の順に回転が伝達されていき、第3伝達棒33の中心軸を回転軸として支持突起39が回転する。このとき、第3伝達棒33の中心軸が鉛直方向と交差する方向に延びているため、支持突起39が回転することで、支持突起39は洗面器100に対して上下動することとなる。   Further, a support projection 39 extending along the central axis direction of the third transmission rod 33 is provided on the outer periphery of one end surface of the transmission member 3 (third transmission rod 33), and the movable member 22 is rotated by rotating the movable member 22. Rotation is transmitted in the order of the first transmission rod 31, the second transmission rod 32, and the third transmission rod 33, and the support protrusion 39 rotates with the central axis of the third transmission rod 33 as the rotation axis. At this time, since the central axis of the third transmission rod 33 extends in a direction intersecting the vertical direction, the support protrusion 39 moves up and down with respect to the washbasin 100 by rotating.

但し、上述の通り、回転規制機構2Aにより可動部材22の回転可能範囲が規制されているため、支持突起39の回転可能範囲も規制されている。詳述すると、図4(a)(尚、図4は、図1のA矢視図である)に示すように、支持突起39が最も下方側に配置されたとき、支持突起39の一端側から見て、支持突起39は第3伝達棒33の回転軸の鉛直下方に配置される。一方で、図4(b)に示すように、支持突起39が最も上方に配置されたとき、支持突起39の一端側から見て、支持突起39は第3伝達棒33の回転軸の鉛直上方からややずれた位置に配置される。すなわち、支持突起39の一端側から見たとき、伝達部材3の一端部(第3伝達棒33)の回転軸から鉛直上方に延びる直線L1上に、支持突起39と後述する通水部材41の外周壁41Aとの接触部分TPが配置されないように支持突起39の回転可能範囲が規制されている(尚、図4においては、通水部材41等は不図示)。   However, as described above, since the rotatable range of the movable member 22 is restricted by the rotation restricting mechanism 2A, the rotatable range of the support protrusion 39 is also restricted. More specifically, as shown in FIG. 4A (note that FIG. 4 is a view taken in the direction of arrow A in FIG. 1), when the support protrusion 39 is disposed on the lowermost side, one end side of the support protrusion 39 As seen from above, the support protrusion 39 is disposed vertically below the rotation axis of the third transmission rod 33. On the other hand, as shown in FIG. 4B, when the support protrusion 39 is disposed at the uppermost position, the support protrusion 39 is vertically above the rotation axis of the third transmission rod 33 when viewed from one end side of the support protrusion 39. It is arranged at a position slightly deviated from. That is, when viewed from one end side of the support protrusion 39, the support protrusion 39 and a water passage member 41 (to be described later) are disposed on a straight line L <b> 1 extending vertically upward from the rotation axis of one end portion (third transmission rod 33) of the transmission member 3. The rotatable range of the support protrusion 39 is restricted so that the contact portion TP with the outer peripheral wall 41A is not arranged (note that the water passage member 41 and the like are not shown in FIG. 4).

また、本実施形態では、図5に示すように、配管111の内周面に対する支持突起39の突出量が比較的小さくされることで、支持突起39の一端部(先端)は前記配管111の中心に到達しないように構成されている。   Further, in the present embodiment, as shown in FIG. 5, the protrusion of the support protrusion 39 with respect to the inner peripheral surface of the pipe 111 is made relatively small, so that one end (tip) of the support protrusion 39 is It is configured not to reach the center.

次に、排水口装置4について説明する。前記排水口装置4は、洗面器100の排水口104等に設けられており、通水部材41と、支持軸42と、ヘアキャッチャー43と、排水口部材44と、栓蓋45とを備えている。   Next, the drain port device 4 will be described. The drain port device 4 is provided at the drain port 104 or the like of the basin 100, and includes a water passage member 41, a support shaft 42, a hair catcher 43, a drain port member 44, and a plug lid 45. Yes.

通水部材41は、環状(本実施形態では、筒状)をなす外周壁41Aを備えており、当該外周壁41Aが配管111の内周面に沿うようにして配管111内に配置されている。また、通水部材41は、その外周壁41Aの下端面が支持突起39に載置状態とされることで、配管111内にて支持されており、支持突起39の上下動に伴って洗面器100に対して上下動するように構成されている。加えて、通水部材41は、その外周壁41Aから排水路の中心に向かって延びる複数のアーム部46を備えており、前記支持軸42の下端部がアーム部46に固定されている。   The water flow member 41 includes an outer peripheral wall 41 </ b> A that forms an annular shape (in this embodiment, a tubular shape), and the outer peripheral wall 41 </ b> A is disposed in the pipe 111 so as to be along the inner peripheral surface of the pipe 111. . The water passage member 41 is supported in the pipe 111 by placing the lower end surface of the outer peripheral wall 41 </ b> A on the support protrusion 39, and the basin is moved along with the vertical movement of the support protrusion 39. It is configured to move up and down with respect to 100. In addition, the water passage member 41 includes a plurality of arm portions 46 extending from the outer peripheral wall 41 </ b> A toward the center of the drainage channel, and the lower end portion of the support shaft 42 is fixed to the arm portion 46.

支持軸42は、鉛直方向に延びる棒状をなし、当該支持軸42の一端(上端)側に位置し、前記栓蓋45の背面中央を支持する一端側支持軸42Aと、支持軸42の他端(下端)側に位置し、他端部が前記通水部材41のアーム部46に固定された他端側支持軸42Bとを備えている。前記一端側支持軸42A及び他端側支持軸42Bは、直列的に配置されるとともに、それぞれが分離可能に構成されている。そして、両支持軸42A,42Bを分離することで、ヘアキャッチャー43を排水口104から取外すことなく、栓蓋45を排水口104から取外すことができるようになっている。また、通水部材41の上下動により、支持軸42ひいては栓蓋45が上下動し、排水口104の開閉が行われるようになっている。   The support shaft 42 has a rod shape extending in the vertical direction, is located on one end (upper end) side of the support shaft 42, and supports one end side support shaft 42 </ b> A that supports the center of the back surface of the stopper lid 45, and the other end of the support shaft 42. The other end side support shaft 42 </ b> B is located on the (lower end) side and the other end portion is fixed to the arm portion 46 of the water passage member 41. The one end side support shaft 42A and the other end side support shaft 42B are arranged in series and are configured to be separable from each other. Then, by separating the support shafts 42A and 42B, the stopper lid 45 can be removed from the drainage port 104 without removing the hair catcher 43 from the drainage port 104. In addition, the support shaft 42 and thus the plug lid 45 are moved up and down by the vertical movement of the water passage member 41 so that the drain port 104 is opened and closed.

前記ヘアキャッチャー43は、髪の毛等を捕集するものであって、前記排水口104のうち鉛直方向にほぼ沿って延びる筒状の垂下部105に対して、その外周縁が接触した状態で配置されている。また、ヘアキャッチャー43は、その中央に鉛直方向に延びる筒状部43Aを備えており、当該筒状部43Aに対して前記一端側挿通部42Aと他端側挿通部42Bの一端部とが挿通されている。栓蓋45を支持する一端側支持軸42Aを、外周縁が排水口104の垂下部105に接触するヘアキャッチャー43により支持することで、支持軸42の中心軸と排水口104の中心軸とがほぼ一致するようになっている。   The hair catcher 43 collects hair and the like, and is arranged in a state in which the outer peripheral edge thereof is in contact with a cylindrical hanging portion 105 extending substantially along the vertical direction in the drain port 104. ing. The hair catcher 43 includes a cylindrical portion 43A extending in the vertical direction at the center thereof, and the one end side insertion portion 42A and the one end portion of the other end side insertion portion 42B are inserted into the cylindrical portion 43A. Has been. The one end side support shaft 42A that supports the plug lid 45 is supported by the hair catcher 43 whose outer peripheral edge is in contact with the hanging portion 105 of the drain port 104, so that the center axis of the support shaft 42 and the center axis of the drain port 104 are Almost matches.

加えて、他端側挿通部42Bの一端部外周面には、径方向外側に突出する環状の突部42Cが設けられており、また、筒状部43Aの内周面には、径方向内側に突出する環状の爪部43Dが設けられている。そして、他端側挿通部42Bの一端部が筒状部43Aに挿通された状態において、前記爪部43Dに対して前記突部42Cが着脱自在に係止可能とされている。   In addition, an annular protrusion 42C protruding radially outward is provided on the outer peripheral surface of one end of the other end side insertion portion 42B, and the radially inner side of the inner peripheral surface of the cylindrical portion 43A. An annular claw portion 43 </ b> D that protrudes from the center is provided. And in the state which the one end part of the other end side insertion part 42B was penetrated by the cylindrical part 43A, the said protrusion 42C can be detachably latched with respect to the said nail | claw part 43D.

前記排水口部材44は、筒状をなしており、自身の上端鍔状部分と所定のナット48との間で、前記垂下部105の下端から径方向内側に延びる鍔部106を挟み込むことにより、排水口104に取付けられている。また、排水口部材44の下端部は、洗面器100からのオーバーフロー水を流すためのオーバーフロー口114を備えた連接管115を介して配管111に接続されており、その結果、排水口104から配管111へと至る排水路が形成されている。   The drain port member 44 has a cylindrical shape, and sandwiches a flange portion 106 extending radially inward from the lower end of the drooping portion 105 between its upper end flange portion and a predetermined nut 48, It is attached to the drain port 104. Further, the lower end portion of the drain port member 44 is connected to the pipe 111 via the connecting pipe 115 provided with the overflow port 114 for allowing the overflow water from the basin 100 to flow. A drainage channel leading to 111 is formed.

前記栓蓋45は、樹脂等からなる円板状の蓋部49と、弾性変形可能な材料からなる環状のパッキン50とを備えている。可動部材22を回転させることにより栓蓋45を下動させ、排水口104を閉じた際には、排水口104のうち下方に向かって縮径するテーパ部107に対して前記パッキン50が圧接し、その結果、栓蓋45と排水口104との間がシールされる。本実施形態では、支持軸42の中心軸と排水口104の中心軸とがほぼ一致するように構成されているため、栓蓋45(パッキン50)の外周縁を排水口104に対してより確実に接触させることができ、ひいては栓蓋45と排水口104との間のシール性の向上が図られている。   The plug lid 45 includes a disk-shaped lid portion 49 made of a resin or the like and an annular packing 50 made of an elastically deformable material. When the stopper lid 45 is moved downward by rotating the movable member 22 and the drain port 104 is closed, the packing 50 is pressed against the tapered portion 107 of the drain port 104 whose diameter is reduced downward. As a result, the gap between the plug lid 45 and the drain port 104 is sealed. In the present embodiment, since the central axis of the support shaft 42 and the central axis of the drain port 104 are configured to substantially coincide with each other, the outer peripheral edge of the plug lid 45 (packing 50) is more reliable with respect to the drain port 104. Thus, the sealing property between the plug lid 45 and the drain port 104 is improved.

以上詳述したように、本実施形態によれば、支持軸42を支持する通水部材41のうち、その外周壁412Aが支持突起39に支持され、支持突起39の先端は配管111の中心に到達しないように構成されている。つまり、配管111の内周面に対する支持突起39の突出量が非常に小さなものとされている。従って、支持突起39に対して毛髪やゴミ等が極めて引っ掛かりにくくなり、配管111の詰まりを効果的に抑制することができる。また、支持突起39から先(下方)に位置する配管111やトラップ(図示せず)等を比較的容易に清掃することができる。   As described in detail above, according to the present embodiment, the outer peripheral wall 412A of the water passage member 41 that supports the support shaft 42 is supported by the support protrusion 39, and the tip of the support protrusion 39 is at the center of the pipe 111. It is configured not to reach. That is, the protrusion amount of the support protrusion 39 with respect to the inner peripheral surface of the pipe 111 is very small. Therefore, hair, dust and the like are hardly caught on the support protrusion 39, and the clogging of the pipe 111 can be effectively suppressed. In addition, the pipe 111, the trap (not shown), and the like that are positioned ahead (downward) from the support protrusion 39 can be cleaned relatively easily.

加えて、可動部材22は、自身の中心軸を回転軸として洗面器100に対して相対回転可能に構成されている。そのため、軸方向に変位する可動部材を用いる場合と比較して、可動部材を支持する部材等の長尺化等が不要となり、操作部2の小型化を図ることができる。その結果、槽体等のうち内部スペースが比較的小さな位置であっても操作部2を配設することができ、栓蓋45や支持軸42に対する操作部2の相対位置関係を比較的自由に設定することができる。   In addition, the movable member 22 is configured to be rotatable relative to the washbasin 100 with its own central axis as the rotation axis. Therefore, compared to the case of using a movable member that is displaced in the axial direction, it is not necessary to lengthen the member that supports the movable member, and the operation unit 2 can be reduced in size. As a result, the operation unit 2 can be disposed even when the internal space of the tank body or the like is a relatively small position, and the relative positional relationship of the operation unit 2 with respect to the plug lid 45 and the support shaft 42 is relatively free. Can be set.

さらに、支持突起39の一端側から見たとき、伝達部材3の一端部の回転軸から鉛直上方に延びる直線L1上に支持突起39が配置されないように支持突起39の回転可能範囲が規制されている。このため、通水部材41に上方から大きな力が加わった際に、支持突起39が回転することとなり、ひいては支持突起39に加わる力を低減することができる。これにより、支持突起39の破損をより確実に防止することができる。   Further, when viewed from one end side of the support protrusion 39, the rotatable range of the support protrusion 39 is restricted so that the support protrusion 39 is not disposed on the straight line L <b> 1 extending vertically upward from the rotation axis of one end portion of the transmission member 3. Yes. For this reason, when a large force is applied to the water passage member 41 from above, the support protrusion 39 rotates, and thus the force applied to the support protrusion 39 can be reduced. Thereby, damage to the support protrusion 39 can be prevented more reliably.

併せて、可動部材22の回転を規制する回転規制機構2Aにより支持突起39の回転可能範囲が規制されている。従って、伝達部材3に対して大きなねじり応力が加わってしまうことを防止でき、伝達部材3の破損等をより確実に防止することができる。   In addition, the rotatable range of the support protrusion 39 is restricted by the rotation restricting mechanism 2 </ b> A that restricts the rotation of the movable member 22. Therefore, it is possible to prevent a large torsional stress from being applied to the transmission member 3, and it is possible to more reliably prevent the transmission member 3 from being damaged.

また、伝達部材3の一端部が斜め下方側に延びているため、伝達部材3の一端部と取付管112との間を伝わった水の漏出をより確実に防止することができる。   Moreover, since the one end part of the transmission member 3 is extended diagonally downward, the leakage of the water transmitted between the one end part of the transmission member 3 and the attachment pipe 112 can be prevented more reliably.

加えて、第3伝達棒33の外周面には凹状の係合部33Aが設けられており、当該係合部33Aに対して取付管112に設けられた凸状の被係合部113が係合されている。従って、取付管112に対する伝達部材3の配設を比較的容易に行うことができ、洗面器100に対する排水栓装置1の組付作業性を一層向上させることができる。   In addition, a concave engaging portion 33A is provided on the outer peripheral surface of the third transmission rod 33, and a convex engaged portion 113 provided on the attachment tube 112 is engaged with the engaging portion 33A. Are combined. Therefore, the transmission member 3 can be disposed relatively easily with respect to the attachment pipe 112, and the workability of assembling the drain plug device 1 with respect to the washbasin 100 can be further improved.

さらに、支持軸42がヘアキャッチャー43により支持されるため、部品点数の低減や構成の簡素化を図ることができ、ひいては製造コストを低減させることができる。   Further, since the support shaft 42 is supported by the hair catcher 43, the number of parts can be reduced and the configuration can be simplified, and the manufacturing cost can be reduced.

また、支持軸42は、一端側支持軸42Aと他端側支持軸42Bとで分離可能に構成されるため、ヘアキャッチャー43を排水口104に配置した状態で、栓蓋45を取外すことができる。これにより、ヘアキャッチャー43を排水口104に配置したまま、ヘアキャッチャー43の上面を清掃するといったことが可能となる。   Further, since the support shaft 42 is configured to be separable between the one end side support shaft 42A and the other end side support shaft 42B, the stopper lid 45 can be removed with the hair catcher 43 disposed at the drain port 104. . Accordingly, it is possible to clean the upper surface of the hair catcher 43 while the hair catcher 43 is disposed at the drain port 104.

さらに、他端側支持部42Bの突部42Cが筒状部43Aの爪部43Dに係止可能とされているため、ヘアキャッチャー43を排水口104から取外すことで、通水部材41も取外すことができる。その結果、配管111に対する通水部材41の着脱をより容易に行うことができ、通水部材41から先の配管111等の清掃をより一層容易に行うことができる。加えて、爪部43Dに対して突部が42C着脱自在であるため、筒状部43A(ヘアキャッチャー43)から他端側支持軸42Bひいては通水部材41を取外すことができ、ヘアキャッチャー43や通水部材41をそれぞれ単独で清掃することが可能となる。   Furthermore, since the protrusion 42C of the other end side support part 42B can be locked to the claw part 43D of the cylindrical part 43A, the water passage member 41 is also removed by removing the hair catcher 43 from the drain port 104. Can do. As a result, the water passing member 41 can be more easily attached to and detached from the pipe 111, and the cleaning of the pipe 111 and the like ahead of the water passing member 41 can be performed more easily. In addition, since the protrusion 42C is detachable from the claw portion 43D, the other end side support shaft 42B and thus the water passage member 41 can be removed from the tubular portion 43A (hair catcher 43). It becomes possible to clean the water flow member 41 individually.

尚、上記実施形態の記載内容に限定されず、例えば次のように実施してもよい。勿論、以下において例示しない他の応用例、変更例も当然可能である。   In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

(a)上記実施形態では、支持突起39が回転することで、通水部材41ひいては栓蓋45が上下動するように構成されているが、図6に示すように、配管111側に向けて下方へと傾斜する傾斜面79Aを有する支持突起79を用い、前記傾斜面79により通水部材41の外周壁41Aを支持した状態で、配管111に対する支持突起79の突出量を変更することで、通水部材41ひいては栓蓋45を上下動させることとしてもよい。この場合においても、上記実施形態とほぼ同様の作用効果が奏されることとなる。尚、配管111に対する支持突起79の突出量を変更可能とするためには、伝達部材80の一端部を配管111に対して接離移動可能(つまり、伝達部材80をその長手方向に沿って移動可能)とすることが必要であり、この点を考慮すると、可動部材として軸方向に変位する押ボタン式のものを用いるとともに、伝達部材80として軸方向の変位をより確実に伝達可能なレリースワイヤ等を用いることが好ましい。   (A) In the above embodiment, the support member 39 is configured to rotate so that the water passage member 41 and thus the plug lid 45 move up and down. However, as shown in FIG. By using the support protrusion 79 having the inclined surface 79A inclined downward, and changing the protrusion amount of the support protrusion 79 with respect to the pipe 111 in a state where the outer peripheral wall 41A of the water passage member 41 is supported by the inclined surface 79, It is good also as moving the water flow member 41 and by extension, the stopper lid 45 up and down.
