Description
本発明は排水栓装置に関するものである。 The present invention relates to a drain plug device.
特許文献１は従来の排水栓装置を開示している。この排水栓装置は、排水栓、排水口部材、及び目皿を備えている。排水栓は排水口部材に形成された排水口を開閉する。排水口部材は、円形状の排水口と、排水口に連続した排水路とを形成している。また、排水口部材は排水路の途中に設けられた十字形状のリブを有している。目皿は、円盤形状であり、４個の円形状の貫通孔が形成されている。目皿は、排水路のリブ上に着脱自在に載置することができる。このため、この排水栓装置は、排水口部材の排水路のリブ上に目皿を載置すると、排水路を流れて排水される単位時間当たりの排水量（以下、排水流量という。）がリブ上に目皿を載置しない場合に比べて少なくすることができる。 Patent Document 1 discloses a conventional drain plug device. This drain plug device includes a drain plug, a drain port member, and a plate. The drain plug opens and closes the drain port formed in the drain member. The drainage port member forms a circular drainage port and a drainage channel continuous with the drainage port. Further, the drainage port member has a cross-shaped rib provided in the middle of the drainage channel. The plate has a disk shape, and four circular through holes are formed therein. The eye plate can be detachably mounted on the rib of the drainage channel. Therefore, in this drain plug device, when a plate is placed on the rib of the drainage channel of the drainage member, the amount of drainage per unit time (hereinafter referred to as the drainage flow rate) flowing through the drainage channel and drained on the rib. The number can be reduced as compared with the case where no eye plate is placed.
しかし、特許文献１の排水栓装置を利用して排水流量を変更しようとすると、その都度、目皿を排水口部材の排水路から着脱する手間を要する。また、この排水栓装置は目皿が排水口を開閉する排水栓と別体である。このため、この排水栓装置において、排水口の開閉と排水流量の変更とは別々の異なった操作になる。 However, if the drainage flow rate is changed by using the drainage plug device of Patent Document 1, it is necessary to attach and detach the perforated plate from the drainage channel of the drainage port member each time. Further, this drain plug device is separate from the drain plug in which the eye plate opens and closes the drain port. Therefore, in this drain plug device, opening and closing the drain port and changing the drainage flow rate are different operations.
本発明は、上記従来の実情に鑑みてなされたものであって、排水口の開閉及び排水流量の変更を容易に行うことができる排水栓装置を提供することを解決すべき課題としている。 The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a drain plug device that can easily open and close a drain port and change a drain flow rate.

この排水栓装置は排水栓が排水口を閉鎖する閉鎖位置と排水流量（単位時間当たりの排水量）が異なる複数の開放位置との間を移動する。このため、この排水栓装置は、排水栓を操作するのみで、排水口の開閉及び排水流量の変更を行うことができる。 In this drain plug device, the drain plug moves between a closed position where the drain port is closed and a plurality of open positions where the drainage flow rate (the amount of drainage per unit time) is different. Therefore, in this drain plug device, the drain port can be opened and closed and the drain flow rate can be changed only by operating the drain plug.
したがって、本発明の排水栓装置は排水口の開閉及び排水流量の変更を容易に行うことができる。 Therefore, the drain plug device of the present invention can easily open and close the drain port and change the drain flow rate.
また、この排水栓装置は、複数の開放位置に排水栓を保持する保持機構を備えているため、排水している際に水圧等の影響によって排水栓が移動して排水流量が変化してしまうことを防止することができる。 Further, since this drain plug device is provided with a holding mechanism that holds the drain plug at a plurality of open positions, the drain plug moves due to the influence of water pressure or the like during draining, and the drain flow rate changes. Can be prevented.
本発明における好ましい実施の形態を説明する。 A preferred embodiment of the present invention will be described.
本発明の排水栓装置は、軸方向に進退することによって前記排水栓を移動させる索状物と、前記索状物を軸方向に進退させる操作部とを備えており、前記保持機構は前記操作部から前記排水栓までの間に組み込まれ得る。この場合、操作部を操作し易い位置に配置し、保持機構を適切な部分に組み込んで排水口の開閉及び排水流量の変更を遠隔操作することができる。 The drain plug device of the present invention includes a cord that moves the drain plug by advancing and retreating in the axial direction, and an operation unit that moves the cord in the axial direction, and the holding mechanism performs the operation. It can be installed between the part and the drain plug. In this case, the operation unit can be arranged at a position where it can be easily operated, and the holding mechanism can be incorporated into an appropriate portion to remotely open and close the drain port and change the drainage flow rate.
本発明の排水栓装置において、前記保持機構は、排水口部材又は前記排水栓の一方に設けられた係止部と、他方に設けられた被係止部とによって構成され得る。この場合、簡易な構成で排水口の開閉及び排水流量の変更を行うことができる。 In the drain plug device of the present invention, the holding mechanism may include a locking portion provided on one of the drain port member or the drain plug and a locked portion provided on the other. In this case, the drainage port can be opened and closed and the drainage flow rate can be changed with a simple configuration.

Meanwhile, they are provided side by side along the upper inner peripheral surface of the case 71. Each locking member 75 has a first locking portion 75A and a second locking portion 75B with which the cam projection 77 of the rotor body 74A is locked. The first locking portion 75A of each locking member 75 is formed at the upper end of the second guide groove 80B formed by cutting out from the lower end of each locking member 75 to the intermediate portion in the vertical direction of each locking member 75. ing. The first locking portion 75A of each locking member 75 has the same tilt angle as the upper surface 77A of the cam projection 77 of the rotor main body 74A, and tilts in the same direction (upper left direction in FIGS. 2 and 3). The lower surface 81A of the first boundary portion 81 extending downward between the first guide groove 80A and the second guide groove 80B has the same inclination angle and the same direction (in FIGS. 2 and 3) as the first locking portion 75A. It is inclined to the upper left). The second locking portion 75B of each locking member 75 is continuously formed at the lower end edge of the second guide groove 80B opposite to the first guide groove 80A, and has the same inclination as the first locking portion 75A. They are inclined at the same angle and in the same direction (upper left direction in FIGS. 2 and 3). Each locking member 75 protrudes below the second locking portion 75B between the second locking portion 75B and the first guide groove 80A, and the lower surface 82A has the same inclination angle as that of the second locking portion 75B. Further, it has a second boundary portion 82 inclined in the same direction (upper left direction in FIGS. 2 and 3). In this drain plug device, the knock rod 73, the rotor 74, and each locking member 75 constitute a holding mechanism.
コイルばね７６は、図２に示すように、回転子７４の回転軸部７４Ｂよりも外側であって、回転子本体７４Ａの下面とケース７１の下面部７１Ｓの上面との間に配置されている。コイルばね７６は、回転子７４、ノック棒７３、及び操作ボタン７２に対して、上方向に弾性力を付与している、 As shown in FIG. 2, the coil spring 76 is arranged outside the rotating shaft portion 74B of the rotor 74 and between the lower surface of the rotor main body 74A and the upper surface of the lower surface portion 71S of the case 71. .. The coil spring 76 applies elastic force to the rotor 74, the knock rod 73, and the operation button 72 in the upward direction,
このような構成を有する排水栓装置は、排水栓３０が閉鎖位置にある状態（図２参照）でコイルばね７６の弾性力に対抗して操作ボタン７２を押し下げると、ノック棒７３が下降するとともに回転子７４が下降する。この際、回転子本体７４Ａのカム突起７７が第１ガイド溝８０Ａを第１境界部８１側の側面に沿って下降する（図３（Ａ），（Ｂ）参照）。回転子本体７４Ａが下降し、カム突起７７の上面７７Ａが第１境界部８１の下面８１Ａに連続する位置になると、コイルばね７６の弾性力によって、回転子７４が回転しながらカム突起７７が第１境界部８１の下面８１Ａに沿ってスライドする（図３（Ｂ）参照）。そして、コイルばね７６の弾性力によって、さらに回転子７４が回転しながらカム突起７７が第２ガイド溝８０Ｂに嵌まり込み、第１係止部７５Ａにカム突起７７が係止する（図３（Ｃ）参照）。この状態で、ワイヤ５０は、排水栓３０が閉鎖位置にある状態に比べて、ケース７１から外方向に送り出され、図４に示すように、排水栓３０が中間高さに位置して開弁した第１開放位置に保持される。つまり、カム突起７７が第１係止部７５Ａに係止しているため、ワイヤ５０がケース７１内に引き込まれず、排水栓３０が第１開放位置から下方に移動することができない状態に保持される。排水栓３０が第１開放位置に保持された状態における排水流量は、後述する排水栓３０が第２開放位置に保持された状態における排水流量よりも少ない。 In the drain plug device having such a configuration, when the drain button 30 is in the closed position (see FIG. 2) and the operation button 72 is pushed down against the elastic force of the coil spring 76, the knock rod 73 descends and The rotor 74 descends. At this time, the cam projection 77 of the rotor main body 74A moves down the first guide groove 80A along the side surface on the first boundary 81 side (see FIGS. 3A and 3B). When the rotor body 74A descends and the upper surface 77A of the cam projection 77 reaches a position continuous with the lower surface 81A of the first boundary portion 81, the elastic force of the coil spring 76 causes the cam projection 77 to move to the first position while the rotor 74 rotates. The first boundary portion 81 slides along the lower surface 81A (see FIG. 3B). Then, due to the elastic force of the coil spring 76, the cam projection 77 fits into the second guide groove 80B while the rotor 74 further rotates, and the cam projection 77 is locked to the first locking portion 75A (see FIG. 3 ( See C)). In this state, the wire 50 is sent outward from the case 71 as compared with the state where the drain plug 30 is in the closed position, and as shown in FIG. 4, the drain plug 30 is located at the intermediate height and opens the valve. Is held in the first opened position. That is, since the cam projection 77 is locked to the first locking portion 75A, the wire 50 is not drawn into the case 71, and the drain plug 30 is held in a state in which it cannot move downward from the first open position. It The drainage flow rate when the drainage plug 30 is held at the first open position is smaller than the drainage flowrate when the drainage plug 30 described later is held at the second open position.
この排水栓装置は、排水栓３０が第１開放位置にある状態（図４参照）でコイルばね７６の弾性力に対抗して操作ボタン７２を押し下げると、ノック棒７３が下降するとともに回転子７４が下降する。この際、回転子本体７４Ａのカム突起７７が第２ガイド溝８０Ｂを第２係止部７５Ｂ側の側面に沿って下降する（図５（Ａ），（Ｂ）参照）。回転子本体７４Ａが下降し、カム突起７７の上面７７Ａが第２係止部７５Ｂに連続する位置になる（図５（Ｂ）参照）と、コイルばね７６の弾性力によって、回転子７４が回転しながらカム突起７７が第２係止部７５Ｂに沿ってスライドし、第２係止部７５Ｂにカム突起７７が係止する（図５（Ｂ）参照）。この状態で、ワイヤ５０は排水栓３０が第１開放位置にある状態に比べて、ケース７１から外方向に送り出され、図６に示すように、排水栓３０が最も高い高さに位置して開弁した第２開放位置（全開位置）に保持される。つまり、カム突起７７が第２係止部７５Ｂに係止しているため、ワイヤ５０がケース７１内に引き込まれず、排水栓３０が第２開放位置（全開位置）から下方に移動することができない状態に保持される。 In this drain plug device, when the drain button 30 is in the first open position (see FIG. 4) and the operation button 72 is pushed down against the elastic force of the coil spring 76, the knock rod 73 is lowered and the rotor 74 is rotated. Goes down. At this time, the cam projection 77 of the rotor main body 74A moves down the second guide groove 80B along the side surface on the second locking portion 75B side (see FIGS. 5A and 5B). When the rotor main body 74A descends and the upper surface 77A of the cam projection 77 reaches a position continuous with the second locking portion 75B (see FIG. 5(B)), the elastic force of the coil spring 76 causes the rotor 74 to rotate. Meanwhile, the cam projection 77 slides along the second locking portion 75B, and the cam projection 77 locks on the second locking portion 75B (see FIG. 5B). In this state, the wire 50 is sent outward from the case 71 as compared with the state where the drain plug 30 is in the first open position, and the drain plug 30 is positioned at the highest height as shown in FIG. The valve is held at the opened second open position (fully open position). That is, since the cam projection 77 is locked to the second locking portion 75B, the wire 50 is not drawn into the case 71, and the drain plug 30 cannot move downward from the second open position (fully open position). Held in a state.
