上記特許文献1に記載の排水栓装置において、伝達部材の一端は操作部に接続され、他端は栓蓋の下方に形成された接続部に対して接続されるが、当該操作部が取り付けられる位置は、施工環境によって異なる。例えば、槽体が浴槽である場合、槽体と洗い場の位置関係や浴室内のレイアウトによって、操作部が取り付けられる位置が変動する。又、介護用浴槽では浴槽の側面に操作部が取り付けられる構造が知られている。
ここで、操作部が取り付けられる位置によっては、操作部と栓蓋を伝達部材によって繋ぐことが困難となる。この時、操作部と栓蓋を強引に繋ごうとすると、伝達部材にねじれが生じたり、屈曲半径が小さくなったりしてしまう恐れがある。このような場合には、排水栓装置の施工が困難となるとともに、伝達部材はインナーワイヤが進退する際に生じる摩擦が大きくなることから、栓蓋の開閉に必要な応力が増大し、操作性の低下、インナーワイヤの座屈による部材の破損等の問題が生じる。
In the drain plug device described in Patent Document 1, one end of the transmission member is connected to the operation portion, and the other end is connected to the connection portion formed below the plug lid, but the operation portion is attached. The position depends on the construction environment. For example, when the tank body is a bathtub, the position where the operation unit is attached varies depending on the positional relationship between the tank body and the washing place and the layout in the bathroom. Further, in a long-term care bathtub, a structure is known in which an operation unit is attached to the side surface of the bathtub.
Here, depending on the position where the operation unit is attached, it may be difficult to connect the operation unit and the plug lid with the transmission member. At this time, if the operation unit and the plug lid are forcibly connected, the transmission member may be twisted or the bending radius may be reduced. In such a case, it becomes difficult to construct the drain plug device, and the friction generated when the inner wire moves in and out of the transmission member increases, so that the stress required for opening and closing the plug lid increases, and the operability increases. Problems such as deterioration of the member and breakage of the member due to buckling of the inner wire occur.

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

However, if the mounting position is adjacent to the washing place and is mounted on the edge of the side facing the shower or faucet, the connecting portion 5 is installed in the direction of FIG. 6 (b). It is easier to install by rotating it.
Finally, the plug lid 9 is pressed from the side to the groove portion 81 of the support shaft 8 to engage the engaging portion 91 of the plug lid 9, and the construction is completed. At this time, the connecting portion 51 is provided above the plug lid 9, and the tubular portion 42, which is the end portion of the transmission member 4, is arranged between the plug lid 9 and the connecting portion 51.

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

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

上記本発明の排水栓装置は、連結部5が飛び出し部14に対して回動可能であることから、操作部2が取り付けられる位置に応じて連結部5側面に形成された開口の向きを調整することで、伝達部材4を飛び出し部14に対して自在に方向調整することが可能となる。これによって、操作部2が取り付けられる位置に関わらず、容易に施工を行うことが可能となるとともに、無理なく伝達部材4を屈曲させることが可能となることで栓蓋9の開閉に必要な応力を低減させて操作性の低下や部材の破損を防止することができる。 In the drain plug device of the present invention, since the connecting portion 5 is rotatable with respect to the protruding portion 14, the direction of the opening formed on the side surface of the connecting portion 5 is adjusted according to the position where the operating portion 2 is attached. By doing so, it becomes possible to freely adjust the direction of the transmission member 4 with respect to the protruding portion 14. As a result, the construction can be easily performed regardless of the position where the operation unit 2 is attached, and the transmission member 4 can be bent without difficulty, so that the stress required for opening and closing the plug 9 can be obtained. Can be reduced to prevent deterioration of operability and damage to members.

本発明の第一実施形態は以上であるが、本発明は上記第一実施形態の形状に限られるものではなく、発明の要旨を逸脱しない範囲において、種々の設計変更を加えても良い。例えば、上記第一実施形態において、連結部5は飛び出し部14との接続箇所において回動可能であったが、接続箇所は回動不能であっても良い。即ち、連結上部と連結中部が相対回転可能である、又は連結中部と連結下部が相対回転可能である等、連結部自身の栓蓋側と伝達部材側が相対回転可能であっても良い。尚、連結部と飛び出し部の接続箇所が回動可能且つ連結部自身の栓蓋側と伝達部材側が相対回転可能であっても良い。
又、上記第一実施形態において、栓蓋は上下方向に変位することによって排水口を開閉していたが、排水栓装置の作動による栓蓋の変位方向は上下方向に限られるものではない。即ち、栓蓋は斜め方向に変位することによって排水口を開閉しても良く、図7に示す第二実施形態のように、略水平方向に変位することによって排水口15を開閉しても良い。この第二実施形態においては、図7より明らかなように、略水平方向に配置された接続部51と栓蓋9の間に、伝達部材4の端部である筒部42が配置され、栓蓋9が略水平方向に変位することで、排水口15を開閉する構造としている。同様に、伝達部材4の屈曲方向は栓蓋9の変位方向等に応じて適宜設定されている。
又、第一実施形態において、排水口は槽体の底壁部に形成されていたが、第二実施形態のように槽体1の底壁部11と側壁部12が交差する角部13に形成されていても良い。
又、本発明の槽体は浴槽に限られるものではなく、洗面ボウルや流し台その他の槽体であっても良い。
