It has been known.

このような遠隔操作により排水口を開閉させる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を有する操作部と、前記可動部材の軸方向に沿った変位を伝達し、栓蓋を支持する支持軸を上下動させることで排水栓を開閉する伝達部材とを具備するものが提案されている。 As a drain plug device that opens and closes the drain port by such remote operation, an operation unit having a movable member that is displaced along the axial direction such as a push button, and the displacement along the axial direction of the movable member are transmitted, There has been proposed one that includes a transmission member that opens and closes a drain plug by moving a support shaft that supports the plug lid up and down.

ところで、上記特許文献１，２に記載の技術においては、栓蓋や支持軸に対する操作部の配設位置関係が限定されてしまうおそれがある。すなわち、伝達部材としてレリースワイヤを用いた場合には、可動部材の変位する範囲に対応するように、可動部材を支持する部材等を軸方向に沿って比較的長くする必要があり、ひいては操作部が比較的大型になってしまう。そのため、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存在する位置に限られてしまう。また、伝達部材としてキックレバーを用いた場合には、第１の棒状部材の延びる方向を栓蓋（支持軸）の移動方向とほぼ等しいものとする必要があり、結果として、操作部を配置可能な位置は限定されてしまう。 By the way, in the technologies described in Patent Documents 1 and 2, there is a possibility that the arrangement positional relationship of the operation unit with respect to the plug lid and the support shaft may be limited. That is, when a release wire is used as the transmission member, the member that supports the movable member needs to be relatively long along the axial direction so as to correspond to the range in which the movable member is displaced. Becomes relatively large. Therefore, the position where the operation unit can be disposed is limited to a position where a sufficient space exists inside the tank body or the structure. In addition, when a kick lever is used as the transmission member, the extending direction of the first rod-shaped member needs to be substantially equal to the moving direction of the plug lid (support shaft), and as a result, the operation unit can be arranged. The position is limited.

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、操作部の小型化を図ることができ、操作部と栓蓋や支持軸との位置関係を比較的自由に設定す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 an object of the present invention is to reduce the size of the operation unit and to set the positional relationship between the operation unit and the plug lid and the support shaft relatively freely. It is in providing the drain plug device which can do.

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.

手段１．槽体の排水口に設けられた栓蓋と、

The movable member is configured to be relatively displaceable with respect to the tank body or the structure along a rotation direction with a central axis of the movable member as a rotation axis.
The transmission member is configured to be rotatable about its own central axis as a rotation axis, and its one end located on the support shaft side can be displaced relative to the tank body by the rotation of the movable member. And

The drain plug device according to claim 1, wherein the transmission member includes a slide mechanism that can be expanded and contracted along its longitudinal direction .

上記手段１によれば、可動部材は軸方向に沿って変位せず、自身の中心軸を回転軸とした回転方向に変位するように構成されている。従って、可動部材を支持する部材等の長尺化等が不要となり、操作部の小型化を図ることができる。その結果、槽体等の内部スペースが比較的小さい場合であっても操作部を配設することができ、ひいては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。
さらに、上記手段１によれば、スライド機構により伝達部材が伸縮可能に構成されている。従って、操作部や栓蓋等の取付位置が異なる様々な形状の槽体等に対応して排水栓装置を設けることができる。また、槽体等に対する排水栓装置の組付をより容易に、かつ、より確実に行うことができる。 According to the means 1, the movable member is configured not to be displaced along the axial direction but to be displaced in the rotational direction with the central axis of the movable member as the rotational axis. Therefore, it is not necessary to lengthen the member or the like that supports the movable member, and the operation unit can be downsized. As a result, even when the internal space of the tank body or the like is relatively small, it is possible to dispose the operation unit, and as a result, 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.

可動部材の回転に伴う変位を伝達部材の一端部へとより確実に伝達するために、伝達部材としては回転（ねじり）に対する剛性に比較的優れる棒状部材を用いることが好ましい。しかしながら、棒状部材を用いたときにおいて、可動部材の回転軸と伝達部材の一端部の回転軸とが一致しない場合には、回転の伝達方向を変換する手段を設けることが必要となる。 In order to more reliably transmit the displacement accompanying the rotation of the movable member to one end of the transmission member, it is preferable to use a rod-like member having relatively high rigidity against rotation (torsion) as the transmission member. However, when a rod-shaped member is used, if the rotation shaft of the movable member and the rotation shaft at one end of the transmission member do not coincide with each other, it is necessary to provide means for converting the rotation transmission direction.

この点、上記手段２によれば、伝達部材はユニバーサルジョイントを備えており、当該ユニバーサルジョイントにより棒状部材の連結角度を自在に変更することができる。従って、伝達部材を屈曲させつつ、伝達部材をその中心軸を回転軸として回転させることができる。その結果、棒状部材を用いることによる回転変位のより確実な伝達を実現しつつ、栓蓋等に対する操作部の相対位置関係をより自由に設定することができる。 In this regard, according to the means 2, the transmission member includes the universal joint, and the connection angle of the bar-shaped member can be freely changed by the universal joint. Therefore, it is possible to rotate the transmission member with the central axis as the rotation axis while bending the transmission member. As a result, the relative positional relationship of the operation unit with respect to the plug lid or the like can be set more freely while realizing more reliable transmission of rotational displacement by using the rod-shaped member.

手段４によれば、ガイド部の端部が槽体等から突出しており、当該突出したガイド部の端部と可動部材とが周方向に沿って面接触している。従って、ガイド部と可動部材との間がより確実にシールされることとなり、槽体等の内部に対するガイド部と可動部材との間を伝わった水の浸入を効果的に抑制することができる。 According to the means 4 , the end portion of the guide portion protrudes from the tank body or the like, and the end portion of the protruding guide portion and the movable member are in surface contact along the circumferential direction. Accordingly, the space between the guide portion and the movable member is more reliably sealed, and the penetration of water transmitted between the guide portion and the movable member with respect to the inside of the tank body or the like can be effectively suppressed.

手段５．前記ガイド部の外周面と前記外周壁部の内周面との間に、周方向に沿って延びる環状の空間部を設けた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 , wherein an annular space portion extending in the circumferential direction is provided between the outer peripheral surface of the guide portion and the inner peripheral surface of the outer peripheral wall portion.

Therefore, it is possible to suppress the intrusion of water from the space portion, and more reliably suppress the intrusion of water into the inside of the tank body or the like.

手段７．前記操作部は、前記槽体又は前記構造物の立壁面に設けられ、前記可動部材の回転軸と前記伝達部材の他端部の回転軸とが異なる方向に延びており、

操作部を槽体等の立壁面に設ける場合においては、可動部材の変位方向と伝達部材の変位方向とが異なる向きとなるのが一般的である。従って、従来技術のように伝達部材としてレリースワイヤを用いる場合などでは、可動部材の変位を確実に伝達するために、槽体等の内部に十分な奥行を設ける必要がある。そのため、槽体等の立壁面と部屋壁等との間に十分な奥行がない場合などには、操作部を立壁面に配置することは極めて困難なものとなってしまう。これに対して、立壁面の少なくとも一部を膨出させることで、槽体等の内部に奥行を確保することも考えられるが、この場合には、槽体等の外観が悪化してしまうおそれがある。 When the operation unit is provided on a standing wall such as a tank body, the displacement direction of the movable member is generally different from the displacement direction of the transmission member. Therefore, when using a release wire as a transmission member as in the prior art, it is necessary to provide a sufficient depth inside the tank body or the like in order to reliably transmit the displacement of the movable member. Therefore, when there is not enough depth between the standing wall surface of the tank body and the room wall, it is extremely difficult to arrange the operation unit on the standing wall surface. On the other hand, it is conceivable to secure the depth inside the tank body by bulging at least a part of the standing wall surface, but in this case, the appearance of the tank body and the like may be deteriorated. There is.

この点、上記手段７によれば、操作部は、外周面に第１傘歯車を有する第１歯車軸と、第２傘歯車を有する第２歯車軸とを備えており、両傘歯車を介して、可動部材から伝達部材の他端部に対する回転の伝達方向が変換可能とされている。従って、可動部材の変位を伝達部材へとより確実に伝達可能としつつ、内部の奥行が比較的狭い槽体や構造物など、様々な槽体等に対してその立壁面へと操作部を設けることができる。 In this regard, according to the means 7 , the operation portion includes the first gear shaft having the first bevel gear on the outer peripheral surface and the second gear shaft having the second bevel gear, and both the bevel gears are interposed. Thus, the transmission direction of rotation from the movable member to the other end of the transmission member can be changed. Accordingly, an operation unit is provided on the vertical wall surface of various tank bodies such as a tank body or a structure having a relatively small depth while allowing the displacement of the movable member to be transmitted more reliably to the transmission member. be able to.

手段８．外周に径方向外側に膨出するフランジ部を有するとともに、内周部分において前記第１歯車軸を回転可能に支持する筒状の第１支持部材と、
前記槽体又は前記構造物の内部に設けられ、前記第２歯車軸を回転可能に支持する第２支持部材とを備え、
前記フランジ部と前記第２支持部材との間で前記立壁面を挟み込むことで、前記両支持部材が前記槽体又は前記構造物に対して固定されており、

Accordingly, it is possible to more effectively suppress water from entering the inside of the tank body or the like.
