Description

  The present invention relates to a remote-operated drain plug device, and more particularly, to provide a remotely-operated drain plug device that improves workability and increases the degree of freedom in design layout and is less prone to failure.

Conventionally, in order to treat drainage generated inside a tank body such as a bathtub or wash bowl, a drain outlet is provided on the bottom surface of the tank body, and the drainage is discharged from the drain port to the sewage side through a piping member. Is widely known. In addition, when water is accumulated in the tank body, there is a method of opening and closing the drainage port using the raising and lowering of the valve member, but opening and closing of the drainage port by this valve member is a position separated from the valve member and the drainage port, for example There is known a remote-operated drain plug device that is operated by operating an operation section provided on an edge of a tank body or on the side of a tank body.
As a well-known remote-operated drain plug device, as described in Patent Document 1, a drain port provided on the bottom surface of the tank body, and an operation unit having an operation body provided above the side surface of the tank body And a cylindrical outer tube, an inner wire that slides forward and backward in the outer tube, and a release spring that biases the inner wire toward the operating portion, and operates the raising and lowering of the valve member. . This remote-operated drain plug device is formed by connecting one end of a release wire to an operation unit and the other end to a lock mechanism fixed in a drain outlet.
Here, the lock mechanism includes a lock shaft fixed to the disc-shaped valve member, a lock mechanism main body fixed to the drain port, and retractably retracting the lock shaft, and inside the lock mechanism. Each time the push-up operation is performed on the lock shaft, the lock shaft is moved upward, the fixed / unlocked state is released, and the valve member is lowered together with the lock shaft by its own weight. These are members that perform alternately.
In the conventional example described in Patent Document 1, the end of the inner wire is disposed coaxially with the lock shaft and the end of the outer tube is connected and fixed to the lower end of the lock mechanism main body at the end of the release wire on the drain outlet side. It becomes.
In such a remote-operated drain plug device, when a pushing operation is applied to the operating body, the inner wire moves to the valve member side in accordance with the operation of the operating body. By performing this movement, the lower end of the lock shaft is pushed up, and the lock shaft can be raised / released in a state where the lock shaft is lifted and lowered by its own weight alternately. As the lock shaft is raised / lowered, the valve member connected to the lock shaft is also raised / lowered. When the valve member is raised, the valve member is separated from the drain port to open the drain port, and when the valve member is lowered, the valve member is The member covers the drain port and closes the drain port alternately. In this way, the drainage port can be opened and closed remotely by operating the operating body of the operation unit located away from the drainage port and the valve member. The inner wire moves to the operating portion side and returns to the original position every time the user releases the pushing operation to the operating body by the action of the return spring (hereinafter, the inner wire is moved to the valve member side. "Advance", moving to the operation unit side is expressed as "reverse").

In contrast to the conventional example described in Patent Document 1 that includes a lock mechanism on the drain port side (valve member side), a remote-operated drain plug device having a lock mechanism on the operation unit side is also well known. It has been. In the conventional example described in Patent Document 2, a drain port provided on the bottom surface of the tank body, an operation unit having an operation body, a cylindrical outer tube, and an outer tube provided above the side surface of the tank body There is a type in which a valve member is operated to move up and down by a release wire including an inner wire that slides forward and backward, and a return spring that urges the inner wire toward an operating portion. In this remote-operated drain plug device, a lock mechanism is connected to an operation portion, and an inner wire of a release wire is connected to a valve member. The lock shaft of the lock mechanism is configured so that the upper end is connected to the operating body and the lower end is in contact with the inner wire of the release wire, and the lock shaft protrudes downward each time a push operation is applied to the operating body. The fixed / unfixed state and the upward movement by the action of the return spring are alternately repeated.
In such a remote-operated drain plug device, when a push operation is applied to the operating body, as described above, each time the operation is performed, the lock shaft protrudes downward and the fixed / unfixed state is released to return the return spring. Ascending upward by the action is repeated alternately.
In a state where the lock shaft protrudes downward and is fixed, the inner wire that contacts the lock shaft also moves forward to the valve member side and pushes up the valve member at the drain port position. Opens. Further, when the lock shaft is unlocked, the inner wire is retracted to the operation portion side by the action of the return spring, so that the valve member is lowered, the drain port is covered with the valve member, and the drain port is closed. In this way, the drain outlet can be opened / closed every time the operating body is pushed.
Japanese Patent Laid-Open No. 9-60073 JP 2004-19393 A

The remote-operated drain plug device configured as described above has the following problems.
1. Difficulty in construction In the remote-operated drain plug device described in Patent Document 1, a lock mechanism is disposed in the drain outlet, and a release wire is connected to the lower end thereof. As a procedure for constructing such a remote-operated drain plug device, after inserting the release wire from the operation unit side and pulling it up from the drain port to the bathtub side, the end of the release wire is connected to the lower end of the lock mechanism, After that, the work is carried out by placing and fixing in the drain. For this reason, the person in charge of construction needs to pull out the release wire from the recessed part of the bottom of the tank body, such as a bathtub, and connect it to the lock mechanism, but if the release wire is made longer than necessary, the release wire will twist in the pipe. Therefore, the release wire cannot be stored properly. Therefore, the release wire pipe or route (the “route” here is not necessarily inserted into the pipe, etc., but is simply placed on the outer surface of the tank body. The release wire can only be prepared with a slightly longer length. Then, the length at which the release wire can be pulled out from the drainage port during construction is only a little from the drainage port, and it is extremely difficult to connect the lock mechanism to the end of the release wire that just protrudes slightly from the drainage port. It was difficult.
In order to solve this problem, in the invention described in Patent Document 2, an advancing / retracting mechanism using screw connection is incorporated on the operation unit side, and the advancing length of the drain wire side end of the release wire is increased by this advancing / retreating mechanism. It is devised as follows. However, in order to configure in this way, it is necessary to incorporate an advance / retreat mechanism on the operation unit side, and the number of members for the advance / retreat mechanism increases, resulting in an increase in cost. Problems with piping layout as described in Piping layout restrictions occur.
2. Restriction of piping layout In the case of a remote-operated drain plug device, it is preferable that the height width of a member near the drain port can be made as narrow as possible. When the drainage pipe near the drainage port of the remote-operated drainage plug device is placed in the underfloor space, if the height width of the member near the drainage port becomes narrower, the underfloor space is narrowed accordingly, and the living space is widened instead. The user's living space can be made comfortable. In addition, when the drain pipe near the drain port of the remote-controlled drain plug device is placed in an indoor living space such as a wash basin, a cabinet or the like is placed under the drain port to store detergent or towels. Therefore, if the height width of the member in the vicinity of the drain port is narrowed, the storage space can be widened up and down accordingly, and the storage amount can be increased or the storage can be given a margin.
However, in the remote-operated drain plug device, the lock mechanism and the release wire require a width in the axial direction for the following reasons.
In the lock mechanism, a certain amount of width is required to perform the function in the axial direction of the lock shaft, such as the length of the lock mechanism body, the lock shaft, and the stroke of the lock shaft (the length of movement when moving forward and backward). It becomes.
The release wire is configured to be rigid in the axial direction and bendable in the lateral direction with a certain degree of flexibility in the lateral direction. However, if the bend diameter is extremely small, it cannot be restored. Possible bending occurs, and the outer tube and the inner wire are damaged called buckling. In order to prevent this buckling, when using a release wire for a remote-controlled drain plug device, a width greater than the minimum bend radius that can be used without damaging the release wire is required in the axial direction of the end of the release wire. become.
In the case of the remote-operated drain plug device described in Patent Document 1, a lock mechanism is disposed on the drain port side, and a release wire is connected to the lower end of the lock mechanism. The total length of the main body in the axial direction and the length equal to or greater than the minimum bending radius of the release wire is required upward from the insertion position of the release wire. Was needed.
In the case of the present invention described in Patent Document 2, since the lock mechanism and the advance / retreat mechanism are arranged on the operation unit side, the problem of the height direction at the drainage port may be examined only in the height direction of the release wire end. In this way, only when the lock shaft of the lock mechanism arranged in the operation unit is arranged in the vertical direction, the operation unit is installed in the tank as in the remote-controlled drain plug device described in Patent Document 1. It is provided on a vertical wall of the body, and when a member such as a release wire is bent in the gap between the wall of the bathtub and the wall of the bathroom, the gap between the wall of the bathtub and the wall of the bathroom is narrow and the operation is On the part side, the total length of the axial length of the lock mechanism main body and the length equal to or greater than the minimum bending radius of the release wire may not be ensured. In particular, in the case of the remote-operated drain plug device described in Patent Document 2, since a width is also required for the advance / retreat mechanism as described above, it is virtually impossible to dispose the operation unit on the vertical inner surface of the bathtub. could not.
The present invention has been invented in view of the above problems, and in a remotely operated drainage plug device, the remote control drainage device is improved in workability, increases the degree of freedom in design layout, and is less likely to fail. Is to provide.

The present invention described in claim 1 includes a drain port provided in the tank body, a valve member that opens and closes the drain port by vertical movement, an operation unit that operates the vertical movement of the valve member, and an operation applied to the operation unit. A remote mechanism comprising a release wire comprising a cylindrical outer tube, an inner wire that slides within the outer tube, and a lock shaft that maintains the rise of the valve member. In the operation drain plug device,
The lock shaft of the lock mechanism is arranged at a position that is substantially parallel and eccentric to the end of the inner wire on the side where the release wire lock mechanism is provided, and interlocks the operation of the lock mechanism with the operation of the inner wire. A remote-operated drain plug device characterized by comprising an interlocking portion to be operated.

  According to a second aspect of the present invention, in the remote-operated drain plug device, the lock mechanism includes a lock shaft and at least a lock mechanism main body that maintains a state of advancement or retraction of the lock shaft. The remote-operated drain plug device according to claim 1, characterized in that:

  According to a third aspect of the present invention, in the remote-operated drain plug device, the lock mechanism is disposed on the operation unit side, and the outer tube end on the operation unit side of the release wire is at least when the valve member is raised. The remote-operated drain plug device according to claim 2, characterized in that, in the axial direction of the inner wire on the operation portion side, the lock mechanism main body portion is fixed to the operation portion side with respect to the valve member side end portion. It is.

  According to a fourth aspect of the present invention, in the remote-operated drain plug device, the lock mechanism is disposed on the valve member side, and the outer tube end portion on the operation portion side of the release wire is at least when the valve member is lowered. The remote-operated drain plug device according to claim 2, characterized in that, in the axial direction of the inner wire on the drain port side, the lock mechanism main body is fixed to the valve member side with respect to the operation unit side end. It is.

In the first aspect of the present invention, the lock shaft and the inner wire are not connected linearly, and the directions are parallel but are arranged in an eccentric positional relationship, that is, in a parallel positional relationship, and the two are interlocked. It is configured as follows. This eliminates the need to connect the end of the release wire to the end of the lock shaft or the lock mechanism on both the operation unit side and the drain port side. Connection work can be performed at a position close to the inner surface of the tank body, and workability is improved accordingly.
In addition, conventionally, in either the drain port side or the operation unit side, the “axial length of the lock mechanism” and the “minimum bending radius of the release wire” are totaled in the axial direction of the inner wire end. Although a length was required, in the present invention, construction is possible if there is a longer width of either “the axial length of the lock mechanism” or “the minimum bending radius of the release wire”, and the underfloor space is narrowed. Or the space between the vertical wall surface of the tank body and the wall surface of the construction site is narrowed, and the degree of freedom in piping layout can be increased. Moreover, if the dimension shape inside a piping member is as usual, since the space which bends a release wire can be enlarged, damage to a release wire can be prevented.
In the present invention described in claim 2, the structure of the lock mechanism can be clarified.
According to the third and fourth aspects of the present invention, the location of the lock mechanism can be clarified.

First, the locking mechanism 8 of the present invention will be briefly described below. Note that “upper and lower” in this paragraph is described based on the upper and lower sides of FIG.
As shown in FIG. 10, the lock mechanism 8 includes a lock mechanism main body portion 10 having a substantially cylindrical shape, and a lock shaft 9 that is inserted into the lock mechanism main body portion 10 so as to be able to advance and retract. In the following description of this paragraph, the description will be based on the top and bottom of FIG.
More specifically, the lock shaft 9 has a substantially rod-like shape, and a gear portion 9a having a projection portion 9b accommodated in a groove portion 10a to be described later inside the lock mechanism 8 main body can be turned freely with respect to the lock shaft 9. Thus, it is provided so that it cannot move in the vertical direction.
The lock mechanism main body 10 has a substantially cylindrical shape and includes a groove 10a therein. In addition, a step portion 10b that meshes with the projection of the gear portion 9a is provided between the groove portions 10a, and the groove portion 10a and the step portion 10b are engaged with the projection portion 9b of the gear portion 9a. An inclined surface 10c for slightly rotating the gear portion 9a is provided.
In the lock mechanism 8 shown in FIG. 10, the lock shaft 9 has a length that always passes through the lock mechanism main body 10 in the vertical direction.
Next, the operation of the lock mechanism 8 will be described.
In the lock mechanism 8, the lock shaft 9 is lowered with respect to the lock mechanism main body 10 as shown in FIG. 10. In this state, the protrusion 9 b of the gear portion 9 a is accommodated in the groove 10 a of the lock mechanism 8, whereby the lock shaft 9 is lowered downward relative to the lock mechanism main body 10. In this state, when the lock shaft 9 is moved upward and brought into contact with the upper end of the lock mechanism main body 10, the projection 9 b comes into contact with the inclined surface 10 c, whereby the gear portion 9 a rotates slightly. After that, when the lock shaft 9 is lifted and the lock shaft 9 is lowered, the gear portion 9a rotates, so that the projection 9b of the gear portion 9a meshes with the step portion 10b between the groove portion 10a and the groove portion 10a. Then, the lock shaft 9 is fixed without being lowered further. At this time, the lock shaft 9 is fixed in a raised state with respect to the lock mechanism main body 10.
When the lock shaft 9 is moved upward again from the state where the lock shaft 9 is raised, the projection 9b of the gear portion 9a again contacts the inclined surface 10c and slightly rotates. Thereafter, by raising the lock shaft 9 and lowering the lock shaft 9, the projection 9 b of the gear portion 9 a is again accommodated in the groove 10 a, and the initial lock shaft 9 is the most with respect to the lock mechanism main body 10. Return to the state of descending downward. Thereafter, each time the lock shaft 9 is moved up and down with respect to the lock mechanism main body 10, the lock shaft 9 is fixed / released with the lock shaft 9 raised relative to the lock mechanism main body 10, and the lock shaft 9 is released. The descent can be repeated alternately.
If necessary, the lock mechanism 8 includes the following 1. To 3. In this way, the direction of use and part of the configuration can be changed as appropriate.
1. If necessary, the length of the lock shaft 9 is adjusted so that the lock shaft 8 protrudes upward only as shown in FIG. 13, or conversely, as shown in FIG. 14, the lock shaft 9 is only downward. The protruding lock mechanism 8 can be obtained. Hereinafter, as shown in FIG. 13, in the lock mechanism 8 that is fixed / released and lowered downward in a state where the lock shaft 9 is raised, the lock mechanism 8 in which the lock shaft 9 protrudes only upward is referred to as an upper type lock mechanism 8, As shown in FIG. 14, the lock mechanism 8 in which the lock shaft 9 protrudes only downward is described as a lower type lock mechanism 8 in the lock mechanism 8 that is fixed / released and lowered downward when the lock shaft 9 is raised. The upper-type lock mechanism 8 and the lower-type lock mechanism 8 are not only determined by the fact that the lock shaft 9 protrudes only upward / only protrudes downward, but is determined by its operation and fixing function. It is. For example, in the lock mechanism 8 that is fixed / unfixed and lifts upward while the lock shaft 9 is lowered, the lock mechanism 8 in which the lock shaft 9 protrudes only upward is not an “upper lock mechanism 8”, but will be described later. This is the “lower locking mechanism 8 with the top and bottom inverted”.
2. In the above description, the lock shaft 9 is lowered by its own weight, but if necessary, an elastic member 11 such as a spring is added to the lock mechanism 8 as shown in FIG. You may comprise so that it may descend | fall with the elastic member 11 instead of dead weight. By doing in this way, the lock mechanism 8 can be used from the state shown in FIG. When the lock mechanism 8 is turned upside down, the lock shaft 9 is naturally lowered by the operation with respect to the lock mechanism main body 10 and is lifted by the elastic member 11. On the other hand, in a state where the lock shaft 9 is lowered, fixing / releasing is performed and the lock shaft 9 is raised alternately.
3. In the above description, for convenience, the lock mechanism body 10 is fixed and the lock shaft 8 is operated to operate the lock mechanism 8. However, the lock mechanism 8 is not necessarily configured as such. You may comprise so that the lock shaft 9 may be fixed with respect to an apparatus and the lock mechanism main-body part 10 side may be moved up and down.

Next, the operating body 6 is connected to the lock shaft 9 by screw connection. Since this connection is a screw connection, it is fixed in both the forward and backward directions with respect to the axial direction of the screw. There is no detachment from the lock shaft 9.
Next, the end of the release wire 7 inside the joint member 14 is pulled up from the drain port 1 a into the bathtub B, and the end of the outer tube 7 a on the drain port 1 a side is connected and fixed to the drain port side wire fixing part 13 a of the support member 13. To do.
At this time, since the end of the outer tube 7a of the release wire 7 is directly connected to the support member 13 instead of the lock mechanism 8, the lock mechanism 8 is compared with the remote-operated drain plug device described in Patent Document 1. Therefore, the construction work can be facilitated.
Next, the first ring portion 13b of the support member 13 is fitted to the convex portion inside the drain port 1a, the support member 13 is fixed to the drain port body 1, and the fitting portion 2a of the valve member 2 is connected to the inner wire. By fitting and fixing to the valve shaft 7e at the end of 7b, the construction of the remote-operated drain plug device of this embodiment is completed.

The operation of the remote-operated drain plug device of the first embodiment will be described below.
When using the remote control type drain plug device of the first embodiment, as shown in FIG. 2, first, the operation body 6 of the operation unit 3 is operated, and the drain port 1a is covered with the valve member 2 so that the drain port 1a is covered. Closed.
At this time, the operation body 6 of the operation part 3 moves to the inner surface side of the bathtub B (left side in FIG. 2), and is in a state of being flush with the inner surface of the bathtub B.
this is,
The inner wire 7b is urged to the operating body 6 side by the action of the return spring 7c. The lock shaft 9 is urged to the operating body 6 side by the action of the elastic member 11 and the fixing is released. This is because the inner wire 7b of the release wire 7 is retracted to the operation unit 3 side.
In this state, when water is discharged into the bathtub B, the water discharge can be stored in the bathtub B because the drain port 1a is closed.
When the operating body 6 is pushed into the operating body 6 from this state and the operating body 6 and the lock shaft 9 are moved to the right side in FIG. 2, the lock mechanism 8 acts as shown in FIG. Fix it while moving to the middle right.
As a result, the rod 7d end at the end of the inner wire 7b on the operation portion 3 side comes into contact with the back surface of the operation body 6 and moves the rod 7d to the right, so that the inner wire 7b is on the drain outlet 1a side. The valve member 2 rises together with the valve shaft 7e, and the valve member 2 is separated from the drain port 1a to open the drain port 1a (as described above, the lock shaft 9 and the operating body 6 are connected by screw connection). Therefore, the connection is not released by the stress of the return spring 7c, and the inner wire 7b is advanced without any trouble).
When the operating body 6 and the lock shaft 9 are pushed again from this state and the operating body 6 and the lock shaft 9 are moved to the right side in FIG. 3, the lock mechanism 8 is actuated and the lock shaft 9 is unlocked. As a result, the lock shaft 9 is moved to the inside of the bathtub B by the urging of the elastic member 11, and the operation body 6 that fixes the advance of the inner wire 7b to the drain port 1a side is also the tank body side (left side in the figure). Therefore, the inner wire 7b is retracted to the operation unit 3 side by the weight of the valve member 2 and the action of the return spring 7c, and returns to the state where the bathtub B drain 1a shown in FIG. 2 is closed.
Thereafter, as described above, every time the pushing operation is repeated into the operating body 6, the inner wire 7b pushes up the valve member 2 to open the drain port 1a by opening / retracting the end of the inner wire 7b due to its own weight or the like. The drain port 1a is alternately closed and the drain port 1a can be freely opened and closed by a remote-operated drain plug device.

In the first embodiment, the lock shaft 9 and the inner wire 7b are not linearly connected, and the operation body 6 is arranged after the direction is parallel but is arranged in an eccentric positional relationship, that is, in a parallel positional relationship. When the lock shaft 9 is moved and fixed to the right side in the drawing as shown in FIG. 3, the end of the inner wire 7 b on the operation unit 3 side is also linked to the lock shaft 9. When the lock shaft 9 is unlocked and moved to the left side in the drawing as shown in FIG. 2, the end of the inner wire 7b on the side of the operation unit 3 is also interlocked with the lock shaft 9. It is configured to move to the left side. That is, the operating body 6 functions as an interlocking portion that interlocks the inner wire 7 b and the lock shaft 9.
Further, in the first embodiment, the lock shaft 9 and the inner wire 7b are not linearly connected, and the lock mechanism 8 is arranged in a parallel but eccentric positional relationship, that is, in a parallel positional relationship. It is no longer necessary to connect the end portion of the release wire 7 to the end portion of the lock mechanism 8 on the operation unit 3 side including In the operation unit 3, the outer tube 7 a end of the release wire 7 and the end of the lock mechanism main body 10 of the lock mechanism 8 on the operation unit 3 side are substantially the same in the axial direction of the inner wire 7 b on the operation unit 3 side. That is, it is fixed to the operation unit 3 side rather than the valve member 2 side end of the lock mechanism main body 10. With this configuration, the lock mechanism 8 is disposed on the operation unit 3 side, and the attachment position of the release wire 7 on the operation unit 3 side is substantially the same position as the case where there is no lock mechanism 8 on the operation unit 3 side. I was able to. When the release wire 7 is connected to the end of the lock mechanism 8 as in the prior art, the total length of the “axial length of the lock mechanism 8” and the “minimum bending radius of the release wire 7” is This is necessary in the axial direction of the lock shaft 9 on the side of the portion 3, but in this embodiment, the “locking mechanism 8 axial length” or “the minimum of the release wire 7, while the lock mechanism 8 is disposed on the operation portion 3 side. Construction is possible if there is a longer width of “bending radius”. For this reason, like the present Example, the operation part 3 should be arrange | positioned on the inner surface of tank bodies, such as bathtub B, and the release wire 7 must be bent in the narrow part of the side surface of a tank body and the wall surface of a building.

The guide tube 15 is a flexible tube tube made of a soft resin, one end connected to the branch tube portion 12b of the joint member 12, and the other end connected to the connection tube portion 5a of the elbow tube portion. Is done.

The remote-operated drain plug device of the second embodiment configured as described above is applied to the bathtub B which is a tank body as follows. Even if not particularly described, the connection locations of the respective members are connected in a watertight manner by screw connection using an adhesive or packing as necessary.
First, one end of the guide tube 15 is connected in advance to the branch tube portion 12b of the joint member 12, and the other end is connected to the connection tube portion 5a of the elbow tube portion.
Next, the drain outlet main body 1 is inserted into the mounting hole provided on the bottom surface of the bathtub B, and the lower surface of the flange portion 1b is brought into contact with the upper peripheral surface of the mounting hole.
Next, after connecting the discharge port 12a of the joint member 12 to the sewage-side piping, it is arranged from below the bathtub B, the male screw of the drain port body 1 is screwed with the female screw of the joint member 12, and the mounting hole The periphery is sandwiched between the lower surface of the flange portion 1b and the upper end portion of the female screw opening of the joint member 12 and fixed to the bathtub B.

At this time, since the end of the outer tube 7a of the release wire 7 is directly connected to the support member 13 instead of the lock mechanism 8, the lock mechanism 8 is compared with the remote-operated drain plug device described in Patent Document 1. Therefore, the construction work can be facilitated.
Next, by connecting the valve member 2 to the lock shaft 9 by screw connection, the construction of the remote control type drain plug device of the present embodiment is completed. The connection between the valve member 2 and the lock shaft 9 is a screw connection. Therefore, the valve member 2 is fixed in both the forward and backward directions with respect to the axial direction of the screw and applied in the axial direction of the screw. The valve member 2 does not come off the lock shaft 9 against stress.

The operation of the remote-operated drain plug device of the second embodiment will be described below.
When using the remote control type drain plug device of the second embodiment, as shown in FIG. 5, first, the operation body 6 of the operation unit 3 is operated, and the drain port 1a is covered with the valve member 2 so that the drain port 1a is covered. Closed.
At this time, the operation body 6 of the operation unit 3 is moved to the inner surface side of the bathtub B (left side in FIG. 5) by the action of the return spring 7c, and is flush with the inner surface of the bathtub B.
In this state, when water is discharged into the bathtub B, the water discharge can be stored in the bathtub B because the drain port 1a is closed.
When the operation body 6 is pushed from this state, the inner wire 7b moves forward in the direction of the drain port 1a, and the shaft portion 7f at the end of the inner wire 7b on the drain port 1a side protrudes to contact the lower surface of the valve member 2. Then, the valve member 2 is further pushed up. By this operation, the lock shaft 9 connected to the valve member 2 by screw connection is also raised. As a result, as shown in FIG. 6, the lock mechanism 8 is operated, the lock shaft 9 is fixed together with the valve member 2 connected to the tip thereof, and the valve member 2 is separated from the drain port 1a. The drain port 1a is opened (as described above, since the lock shaft 9 and the valve member 2 are connected by screw connection, the lock shaft 9 is detached from the valve member 2 when the valve member 2 is pushed up by the inner wire 7b. It is pulled up by the valve member 2 without doing). Since the inner wire 7b is not particularly fixed by the valve member 2 or the lock shaft 9, when the pushing operation to the operating body 6 is released, the inner wire 7b is moved back to the operating portion 3 side by the action of the return spring 7c. It becomes the state of.
When the operation member 6 is pushed again from this state and the shaft portion 7f of the inner wire 7b is pressed against the lower surface of the valve member 2 to raise the valve member 2 again, the lock shaft 9 is also raised along with the valve member 2. Then, the lock shaft 9 is unlocked. As a result, the push-in operation to the operating body 6 is released, and when the inner wire 7b and the shaft portion 7f at the end of the inner wire 7b are retracted to the operation portion 3 side by the action of the return spring 7c, the lock shaft 9 is attached to the valve member 2. It descends due to the weight and the weight of the lock shaft 9 itself, and returns to the state where the drain port 1a is closed as shown in FIG.
Thereafter, as described above, every time the pushing operation is repeated into the operating body 6, the inner wire 7b pushes up the valve member 2 to open the drain port 1a by opening / retracting the end of the inner wire 7b due to its own weight or the like. The drain port 1a is alternately closed and the drain port 1a can be freely opened and closed by a remote-operated drain plug device.

In the second embodiment, the lock shaft 9 and the inner wire 7b are not linearly connected, and the valve member 2 is arranged after being arranged in a parallel but eccentric positional relationship, that is, in a parallel positional relationship. The lock shaft 9 is also configured to be interlocked and lifted so that both are linked together, that is, when the inner wire 7b pushes up the valve member 2 as shown in FIG. That is, the valve member 2 functions as an interlocking portion that interlocks the inner wire 7 b and the lock shaft 9.
Further, in the second embodiment, the lock shaft 9 and the inner wire 7b are not linearly connected, and the lock mechanism 8 is arranged in a parallel but eccentric positional relationship, that is, in a parallel positional relationship. It is no longer necessary to connect the end of the release wire 7 to the end of the lock mechanism 8 on the side of the drain port 1a provided with In the drain port 1a, in the axial direction of the inner wire 7b on the drain port 1a side, the end of the outer tube 7a of the release wire 7 and the upper end of the lock mechanism body 10 of the lock mechanism 8 are substantially the same position, that is, the lock mechanism. The main body 10 is fixed to the valve member 2 side (= upper end side) than the operation unit 3 side end portion (= lower end of the lock mechanism 8). With this configuration, the lock mechanism 8 is disposed on the drain port 1a side, and the attachment position on the drain port 1a side of the release wire 7 is set to be approximately the same position as when the lock mechanism 8 is not disposed on the drain port 1a side. I was able to. When the release wire 7 is connected to the end of the lock mechanism 8 as in the prior art, the sum of the “axial length of the lock mechanism 8” and the “minimum bending radius of the release wire 7” is the drainage port. Although it is necessary in the axial direction of the lock shaft 9 on the 1a side, in this embodiment, the lock mechanism 8 is disposed on the drain port 1a side while the “length in the axial direction of the lock mechanism 8” or “the minimum bending of the release wire 7”. Construction is possible if there is a longer width of “radius”. For this reason, the pipe below the drain port 1a can be made narrower in the vertical direction than before, and when the pipe is arranged in the underfloor space, the vertical width of the underfloor space is reduced accordingly, and the pipe is placed in the cabinet or the like. Therefore, the storage space can be widened up and down accordingly.

The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the above embodiment, all of the remote-operated drain plug devices are constructed in the bathtub B, but the present invention is not limited to the above embodiment, and a wash basin equipped with a wash bowl as a tank body, a tank body As long as it is a tank body provided with the drain port 1a, such as a sink equipped with a sink, it may be adopted in any tank body of any drainage device.

  Moreover, in the said Example, when the lock mechanism 8 is provided in either the drain outlet 1a or the operation part 3, the release shaft is set with the lock shaft 9 of the lock mechanism 8 at the center of the opening of the drain outlet 1a or the operation part main body 4. 7 is disposed at an eccentric position deviated from the center, but the present invention is not limited to the above embodiment, and the inner wire 7b of the release wire 7 is connected to the drain port 1a or the operation portion main body 4. The locking mechanism 8 and the lock shaft 9 may be arranged at an eccentric position off the center at the center of the opening.

  Moreover, in the said Example, although the lock mechanism 8 is comprised by the mechanical type lock mechanism 8 provided with the gear part 9a, and what is called a thrust lock type lock mechanism 8, this invention is limited to the said Example. Instead, a mechanical lock mechanism 8 that does not use another gear portion 9a, a lock mechanism 8 that has a packing disposed on the side surface of the lock shaft 9 and holds the position by friction between the packing and other members, and the like are used. It may be configured.

Moreover, in the said Example, the lock mechanism main-body part 10 is provided in the side of the member fixed to the bathtub B which is a tank body, such as the drain outlet main body 1 and the operation part main body 4, and the operation body 6 and the valve member 2 etc. operate | move. However, the present invention is not limited to the above embodiment.
For example, when the lock mechanism 8 is provided on the operation unit 3 side, the lock mechanism main body 10 is fixed to the operation body 6 and the lock shaft 9 is fixed to the operation unit main body 4 as in the operation unit 3 shown in FIG. You may comprise as an integral member (The structure by the side of the drain port 1a is made the same as that of a 1st Example). In the case of FIG. 8, the lock mechanism 8 uses a lower lock mechanism 8 and includes an elastic member 11 similar to that shown in FIG. 15. As the direction of the lock mechanism 8, when the lock shaft 9 is moved up and down as in the embodiment of FIG.
In the case of the embodiment in which the operating body 6 includes the lock mechanism main body 10 as described above, the positional relationship between the lock mechanism main body 10 and the end of the outer tube 7a on the operating section 3 side changes every time the operating body 6 operates. However, at least when the valve member 2 is raised, in the axial direction of the inner wire 7b on the operation portion 3 side, the operation portion 3 side of the outer tube 7a is closer to the operation portion 3 side than the valve member 2 side end portion of the lock mechanism main body portion 10. If the end is fixed, the construction can be performed with a width narrower than the total length of “the axial length of the lock mechanism 8” and “the minimum bending radius of the release wire 7”. It is suitable when the construction is performed on a narrow part where the width cannot be taken so much.

Further, when the lock mechanism 8 is provided on the drain port 1a side, the lock mechanism main body 10 is fixed to the valve member 2 and the lock shaft 9 is fixed to the drain port main body 1 as in the drain port 1a shown in FIG. You may comprise as an integral member (the structure by the side of the operation part 4 shall be the same as that of a 2nd Example). In the case of FIG. 9, the upper locking mechanism 8 is used as the locking mechanism 8, and the direction of the locking mechanism 8 is reversed up and down in FIG. Further, the elastic member 11 and the like are not arranged inside the lock mechanism 8.
Thus, in the case of the Example which provided the lock mechanism main-body part 10 in the valve member 2, the positional relationship of the lock mechanism main-body part 10 and the outer tube 7a edge part by the side of the drain port 1a changes whenever the valve member 2 raises / lowers. However, at least when the valve member 2 is lowered, in the axial direction of the inner wire 7b on the drain port 1a side, the valve member 2 side (= upper end side) than the operation part 3 side end portion (= lower end side) of the lock mechanism body 10 ), The construction can be performed with a width narrower than the total length of “the axial length of the lock mechanism 8” and “the minimum bending radius of the release wire 7”. The width can be reduced, which is preferable.
