The release wire includes a hollow outer tube that is flexible in the lateral direction and rigid in the axial direction, an inner wire that is housed inside the outer tube and that is slidable in the axial direction, and one of the inner wires. And a return shaft that urges the inner wire toward the operating portion side.
Furthermore, in this first conventional example, an operating shaft called a thrust lock mechanism is provided at the end of the release wire on which the valve shaft is not provided, and the operating shaft is advanced each time a pushing operation is applied to the operating shaft. It is provided with a support mechanism portion that incorporates a mechanism that repeats (lowers), releases / fixes, and is urged by the inner wire of the release wire to retreat (rise).
The elbow member includes an opening provided with a female screw that engages with a male screw of the drain plug body, a discharge port for discharging drainage flowing from the drain port to the sewage side, and an insertion port through which the release wire is inserted. Become.

The operation portion main body is a member that is substantially cylindrical and is attached to the operation portion attachment hole. The release portion is inserted into the inside of the operation portion main body, and is detachably stored and fixed in a state where the support mechanism portion is stored.
The button member is a disk-shaped member, and the outer surface of the button member is configured to substantially match the inner surface of the operation portion main body, and to be fitted to the tip of the operation shaft at the center of the lower surface.
The guide tube is a long cylindrical member made of vinyl chloride having rigidity in the axial direction and flexibility in the lateral direction, one end being the insertion port of the elbow member and the other end being the lower end portion of the operation unit main body. And connected to each other.

When attaching the remote-operated drain plug device configured as described above to a bathtub, which is a tank body, first, attach the drain plug body from above the bathtub to the upper surface of the peripheral edge of the drain plug mounting hole provided in the bathtub. Further, the drain plug main body and the elbow member are screwed together, and the drain plug main body and the elbow member are fixedly attached to the drain plug mounting hole.
Next, the operation part main body having the guide tube attached in advance is inserted into the operation part attachment hole provided in the upper edge of the bathtub, and the operation part main body is attached and fixed to the operation part attachment hole. Thereafter, the other end of the guide tube is connected to the insertion port of the elbow tube.
Further, the release wire is inserted into the operation portion main body with the valve shaft side as a tip, and the support mechanism portion is housed and fixed in the operation portion main body.
At this time, the tip of the release wire is guided by the guide tube, and is inserted into the elbow member from the insertion port via the guide tube. From this state, the tip of the release wire is pulled up from the inside of the drain port to the inside of the bathtub while using a jig such as radio pliers.
Further, after connecting the end of the release wire to the support member, the support member is fitted and fixed to the uneven portion in the drain port. Thereafter, the valve shaft portion at the end of the inner wire is fitted into the fitting portion of the valve member.
Further, the operation body fitting portion of the operation body is fitted to the upper end of the operation shaft, and the installation of the drainage device of the first conventional example is completed.

When using the drainage device of the first conventional example, first the state that the valve body closed the drainage port by pushing operation to the button member of the operation unit, that is, the inner wire of the release wire retracted to the operation unit side, The valve member is in a lowered state. If the button member is pushed from this state and the inner wire is advanced to the drain port side, the valve shaft at the tip of the inner wire rises to push up the valve member and the valve body rises to open the drain port. To do. This open state is fixed when the operating shaft is lowered by the thrust lock mechanism, and is maintained when the lower end of the operating shaft comes into contact with the end of the inner wire being advanced.
When the operating body is pushed again from this state and the operating shaft of the thrust lock mechanism is released from the fixed state, the inner wire retracts toward the operating portion due to the weight of the valve member or the action of the return spring, and the valve shaft portion Since it descends, the valve member pushed up by the valve shaft part also descends and the valve body closes the drain port. Thereafter, by repeating this operation, the drain outlet can be freely opened and closed.

As a problem of the drainage device of the first conventional example configured as described above, the lower surface of the flange portion of the drainage plug body of the drainage device is mounted and fixed on the upper surface of the opening peripheral edge provided on the bottom surface of the tank body. Therefore, an upward groove is formed between the bottom surface of the tank body and the flange, and it becomes difficult to take out fine dust or hair that fits in the groove, and the cleaning performance is deteriorated, and the dust accumulated in the groove portion adheres to the groove. There was a problem that the various bacteria propagated and became unsanitary.
In addition, there is a problem that the design is deteriorated due to a difference in color tone and texture due to a difference in material between the drain plug main body and the bottom of the bathtub or a difference in material between the drain plug main body and the bathtub bottom.
In order to solve this problem, the drainage device of the second conventional example in which the drainage plug body and the tank body are integrated as described in Patent Document 2 is proposed for the bathtub, the drainage cock body, and the support member. .

The drainage device of the second conventional example illustrated in FIG. 21 includes a bathtub, a valve member, a support member, a release wire, an operation unit, an elbow member, and a guide tube as tank bodies described below.
The valve member is in contact with an upper edge of a hanging part of a bathtub, which will be described later, and closes the upper edge of the hanging part upstream of the drain port, and a cylindrical part provided on the lower surface of the valve body It becomes more.
The support member is a member that is housed and fixed in the drain, and includes a shaft housing portion that connects an end portion of a release wire, which will be described later, an annular edge portion disposed on the first locking portion, and an annular edge portion. It is provided with a second locking portion with elasticity, which is provided downward and which is recessed outwardly to lock with the first locking portion in the drain outlet. With the release wire connected to the shaft housing portion, the first locking portion and the second locking portion are locked, whereby the end portion of the release wire can be fixed to the drain plug body.
Furthermore, in this conventional example, each time the push operation is performed on the lower end with an inner wire, called a rod-shaped valve shaft portion and a thrust lock mechanism, the valve shaft portion is raised and fixed / unfixed. And a mechanical mechanism that repeatedly descends due to its own weight.
The release wire includes a hollow outer tube that is flexible in the lateral direction and rigid in the axial direction, and an inner wire that is housed inside the outer tube and that is slidable in the axial direction.
The elbow member is a member that is attached below the periphery of the drain outlet of the bathtub, and includes a discharge portion for discharging drainage flowing from the drain outlet, and an insertion port through which the release wire is inserted.
The operation unit is a member for operating the release wire. One end of the guide tube is connected to the operation unit, and the release wire is inserted through the inside of the guide tube to perform an operation applied to the operation unit. The valve member is moved up and down to open and close the drain port by transmitting to the drain port side via the release wire.
Moreover, the remote control type drain plug device which consists of said each member is constructed to the bathtub which is a tank body as described below.
The bathtub is a box that is open at the top, and is provided with a hanging portion formed by a wall surface hanging in a cylindrical shape on the bottom surface, and a first locking portion that protrudes inward from the lower end of the hanging portion.

When attaching the remote-controlled drain plug device configured as described above to a bathtub that is a tank body,
The operation unit main body and the elbow member are connected via a guide tube, and the release wire connected to the operation unit main body is disposed inside the elbow member via the guide tube.

From this state, the end of the release wire is pulled up into the bathtub through the drain and connected to the support member, and the second locking portion of the support member is locked and fixed to the first locking portion of the bathtub. Further, the valve member is disposed so that the cylindrical portion covers the shaft housing portion, and the attachment of the drainage device of the second conventional example is completed.
In addition, Patent Document 2. In the second conventional example, because the installation procedure of the drainage device is not described, the construction procedure until the state of the above paragraph 0008 is not described in particular,
-Place the annular edge of the support member on the first locking part-The second locking part provided below the annular edge has elasticity-The release wire is connected to the lower end of the shaft storage part Since it is clear that the support member to which the release wire is connected is connected from above the bottom surface of the bathtub, the release wire, the support member, and the valve member are constructed by the procedure described in Paragraph 0009. it is obvious.

When using the drainage device of the second conventional example, first the operation body of the operation section is operated and the valve body closes the drainage port, that is, the inner wire of the release wire is retracted to the operation section side, The member is in a lowered state. When the inner wire is advanced toward the drain outlet side by pushing the operating part from this state, the tip of the inner wire raises the valve shaft portion to push up the valve member, and the valve body also rises to open the drain port. To do. This open state is fixed and maintained by a thrust lock mechanism.
From this state, push the operation part again to release the fixed state of the valve shaft part of the thrust lock mechanism, the valve member and valve shaft part will drop due to its own weight, and the valve body will hang down in contact with the upper edge of the hanging part. Close the drainage port together with the upper edge.
Thereafter, by repeating this operation, the drain outlet can be freely opened and closed.

JP 2002-88553 JP 2010-1678

In the case of the remote control drain plug device described in Patent Document 1 and Patent Document 2 as described above, there are problems as described below.
1. Since the support member is connected from above to the uneven part of the drain plug body attached to the tank body or the first engagement part provided in the bathtub, at least one of the remotely operated drain plug devices such as elbow members on the tank body In a state in which the member of the part is attached, it is necessary to perform the construction in such a procedure that the release wire is pulled out from the drain outlet and connected to the support member, and further the support member is connected to the tank body side. This work is performed on the drain port provided on the bottom surface of the tank body, where the person leans into the tank body and is further away from the opening of the tank body (that is, a place where viewing and work are difficult) It was very troublesome to pull out the release wire from the narrow drainage port provided on the bottom of the tank body or to connect it to the support member. Further, depending on the work procedure, it may take more time to move the front side (upper surface or inner surface) of the tank body and the rear side (lower surface or outer surface) of the bathtub many times. In addition, due to the difficulty of work, construction defects may occur, and the quality of the product may be deteriorated. This is a prominent problem particularly in the case of a bathtub which is a large tank.
2. Since the support member is disposed inside the drain port, the support member becomes an obstacle when cleaning the drain port, and it becomes difficult to clean the inside of the drain port. In particular, as in the remote-operated drain plug device disclosed in Patent Document 2, a support that has a structure in which a shaft storage portion is disposed at the center of the support member and an annular edge portion is disposed on the outer periphery, and a rib is provided between them. In the case of a member, in many cases, dust enters the gap between the inner surface of the drain outlet (or the inner surface of the drooping portion) and the annular edge and becomes unsanitary due to the propagation of germs. In addition, ribs become obstacles, and it is difficult to use tools such as brushes for cleaning, which often causes deterioration of cleanability and unsanitary conditions.
3. In the drainage device of the first conventional example described in Patent Document 1, as described above, an upward groove is formed between the bottom surface of the tank body and the flange portion, and it is difficult to take out because fine dust or the like is fitted into this groove. As a result, there were problems such as poor cleaning and non-hygiene.
In addition, there is a problem that the design is deteriorated due to a difference in color tone and texture due to a difference in material between the drain plug main body and the bottom of the bathtub or a difference in material between the drain plug main body and the bathtub bottom.
In addition, the release wire connected to the support member often bends in the elbow member from the upper side where the drainage port is located to the horizontal direction where there is a connection hole or 180 degrees, and is bent upward. However, there was a case where breakage of the release wire called “buckling” occurred. In particular, when the release wire is not fixed, the release wire bends with a small bending radius from directly below the connection point inside the elbow member, even if there is a margin enough to bend inside the elbow member. There was a problem that buckling often occurred.
4). In the drainage device of the second conventional example described in Patent Document 2, a part related to water stop and connection of members such as a water stop surface and a hanging part provided in the tank body uses molding of the tank body, or the tank body. It is comprised by processing by post-processing after molding.
However, when the shape is formed by molding, the tank body is a large member as compared with the drain plug main body, and therefore a considerably high accuracy is required to ensure the function. For example, even with the same 0.1% strain, a 100mm drain plug body will only have a strain of about 0.1mm and no water leakage will occur, but a 1600mm bathtub will have a 1.6mm strain, which will cause water leakage. Therefore, it has been very difficult to give the tank body such as a bathtub the same function as the drain plug body by this molding method.
Even when the shape is formed by post-processing, the tank body is a large member, and it may be difficult to easily move or fix the tank body in a state where it is easy to work. For example, if it is going to perform shape processing from the upper surface of a tank body to a drooping part, an operator will have to reach to the deep part of a tank body and must operate equipment. For this reason, there is a limit to the degree of freedom of shape processing, and it is also difficult to form perfect circles, concentric circles, and fine irregularities, and if the processing fails, the entire tank is wasted. There was a case.
5. In the drainage device of the second conventional example described in Patent Document 2, the method and know-how for manufacturing a large member such as a tank body are completely different from the method and know-how for manufacturing a small member such as a drainage device. The manufacturer that manufactures the body is often different from the manufacturer that manufactures each member such as the valve member of the remote-controlled drain plug device. That is, since the valve member and the water stop surface are manufactured by different manufacturers, the quality control of the match between the valve member and the water stop surface, that is, the quality control of the water stop performance, is compared to the case where the valve member and the water stop surface are manufactured by a single manufacturer. There was a problem that it became difficult.
The present invention has been invented in view of the above-mentioned problems, is easy to construct, has good cleaning properties and design properties, is less likely to cause deterioration and breakage of members such as buckling, and further manufacture and quality control of members. Is to provide a good remote-operated drain plug device.

And the remote-operated drain plug device according to any one of paragraphs 0013 to 0022, wherein the operation portion main body 8 is connected and fixed.

  The present invention according to claim 12 is the remote-operated drain plug device according to paragraph 0023, characterized in that in the remote-operated drain plug device, the guide tube 15 is configured to be extendable in the axial direction. It is.

In this invention of Claim 1, it forms in the drainage device attached from the lower surface of a tank body, and the inner side rather than the periphery of the tank drainage port 1 at the time of completion of construction. a position protrudes, the upper end of the tank body discharge port 1 that has been configured to so that is disposed below, also mounted from below the tank body, the drain plug body fixedly connected to release wire ends When the construction is completed, it can be placed at a fixed height relative to the water stop surface.
For example, in the first conventional example and the second conventional example, the water stop surface is arranged on the upper surface of the tank body. Since the thickness of the tank body varies depending on the product, it is necessary to position and fix the end portion of the release wire with respect to the upper surface of the tank body when the water stop surface is arranged on the upper surface of the tank body.
On the other hand, since the release wire itself is disposed through the back surface or the bottom surface of the tank body, the construction procedure is as follows. First, attach the drain plug body etc. to the tank body, and connect the release wire from the back surface or the bottom surface of the tank body. A method / procedure of pulling up through the drainage port, connecting to the support member, and positioning and fixing the support member with respect to the upper surface of the tank body had to be adopted.
On the other hand, as described above, in the present invention according to claim 1, the water stop surface for closing the drainage device drainage port is formed in the drainage device attached from the lower surface of the tank body, and the tank body at the time of completion of construction. a position protruding inward from an edge of the discharge port 1, the upper end of the tank body discharge port 1 is configured so that is arranged below, also the drain plug body further connected secure the release wire ends Since it is configured to be attached from the bottom surface of the tank body, the release wire end can be placed at a fixed height with respect to the water stop surface when construction is completed, regardless of the thickness of the tank body. I can do it now.
As a result, the following 1. To 5. Excellent effects as described in the above.
1. In the construction work of the remote control type drain plug device, it was configured to attach the member with water stop surface and the drain plug body from below the tank body and the operation unit body from the back side of the tank body. The assembly work from the drain plug body to the operation section body, such as connecting the wire to the drain plug body and the operation section body, is performed in advance at the factory, for example, and the remote operation type drain plug device is simply attached to the tank body. It is only necessary to attach the drain plug body and the operation section body to the tank body. That is, like the conventional remote-operated drain plug device, after attaching the operation unit body and drain plug body to the bathtub, the release wire is inserted from the operation unit body toward the drain plug body, and further into the tank body. Leaving yourself and connecting the members by pulling out the release wire from the narrow drainage port provided on the bottom of the tank body, which is the farthest from the opening of the tank body (that is, the place where visibility and work are difficult), There is no need to say.
Even in the present invention, the point of connecting the members by inserting a release wire between the operation unit main body and the drain plug main body or connecting the members by pulling out the release wire from the drainage device drain port is the same as the conventional example. Similarly, in the case of the present invention, the drain plug main body and the operation section main body are not connected to the tank body, and the two are connected by inserting a release wire between the operation section main body and the drain plug main body. Alternatively, the members can be connected by pulling out the release wire from the drain port of the drainage device. For this reason, the assembly work from the drain plug body to the operation section body can be performed in an environment where a large work space such as a factory can be taken and a work table that facilitates the work is installed and equipment is available. it can. In addition, since the remote assembly type drain plug device itself is not connected to the tank body, the worker can visually recognize small and lightweight members such as the drain plug body and operation section body. Easy-to-operate, hand-operated, placed at an easy-to-operate position and angle, and can be moved and rotated as necessary to perform work, far more remotely operated than the conventional example Can be easily assembled. In addition, even if it is constructed so that the remote control type drain plug device is attached to the tank body after attaching the member with the water stop surface to the remote control type drain plug device side, Even if it constructs so that an operation type drain plug device may be attached to a tank, either may be sufficient.
2. By attaching a member having a water stop surface and a drain plug main body from below the tank body, a part of the drain plug main body is not disposed on the bottom surface of the tank body, and a groove facing upward is formed. Things disappeared (a member with a water stop surface and a drain plug body in the tank drain outlet were exposed, but this was not "on the bottom of the tank body").
At the lower end of the tank body drain outlet of the tank body, there is a groove that becomes a joint with a member having a water stop surface, a drain plug body, a connecting member, etc., which will be described later. Since it is formed facing the center of the mouth, that is, facing in the horizontal direction, dust and hair can be taken out very easily compared to the conventional example in which the groove faces upward, and the cleaning property is very good. To improve.
3. The drain plug main body is covered with the valve member and is disposed at substantially the same height as the bottom surface of the tank body drain port so that it is hardly visible or completely invisible from the inner surface side of the tank body.
For this reason, the cleaning performance of the tank body is improved, and the difference in color and texture due to the difference in material between the drain plug body and the bottom of the bathtub and the difference in color and texture due to the difference between the drain plug body and the bottom of the bathtub deteriorates the design. The problem such as can be solved.
4). Since the water stop surface that contacts the valve member and prevents the drainage of the waste water in the tank body is provided as a separate member from the tank body, a particularly high accuracy is required for molding the bathtub as in Patent Document 2, There is no such thing. In addition, for post-processing of the tank body, for example, it is only necessary to form a round opening (tank drain port) and the peripheral edge of the bottom surface of the tank body flat and horizontal, and provide unevenness inside the tank drain port. It is not necessary (if unevenness is required, it can be provided on the drain plug body). For this reason, compared with the invention of patent document 2, the freedom degree of the shape of a hanging part and a drain port part, and the ease of a process increased greatly. In addition, since the processing became easy, there was almost no problem that the entire bathtub was wasted due to failure to mold the tank body.
Moreover, fine members other than the tank body such as the drain plug body can form a complicated shape with high accuracy from the beginning by resin molding. For this reason, it has become possible to easily provide a perfect circle, concentric circles, and fine irregularities at a tank body drain port with extremely high accuracy without any post-processing.
5. The valve member and the drain plug body are usually manufactured by the same manufacturer because the size of the member does not change much compared to the tank body. Thus, since the drain plug main body provided with the valve member and the water stop surface is manufactured by the same manufacturer, the quality control of the match between the valve member and the water stop surface, that is, the quality control of the water stop performance is described in Patent Document 2. Compared with the conventional example, it became extremely easy.
In the invention according to claim 2, by carrying out the construction through the connecting member, a mechanism / structure that can be easily and reliably connected to the drain plug body is built into the connecting member, and the connecting member is installed in the factory in advance. It is possible to complete the construction by simply connecting the drain plug main body and the connecting member at the site.
In addition, when a structure such as a discharge port is provided on the side surface of the drain plug main body, even if an attempt is made to connect the tank body and the drain plug main body with a screw member or the like, the portion protruding on the side surface becomes an obstacle and the screw member May not be attached. In such a case, as described above, a mechanism / structure that can be easily and reliably connected to the drain plug body is incorporated into the connection member, and the tank body and the connection member are connected with a screw member, and then the connection member and the drain plug are connected. If the connection with the main body is connected, even if the drain plug main body has a protruding portion in the side surface direction, the highly reliable tank body and the drain plug main body can be connected in a watertight manner.
In this invention of Claim 3, Claim 4, the member which has a water stop surface can be clarified.
In invention of Claim 5, the structure which connects a drain plug main body and a release wire end part so that attachment or detachment is possible can be shown concretely.
In invention of Claim 6, the structure which connects a drain plug main body and a release wire end part so that attachment or detachment is possible can be shown concretely.
Furthermore, in the invention according to claim 6, when the valve member is removed, there is no support member at the tank body outlet and the drainage apparatus outlet, and there is only a holder portion at the center. When cleaning the drain port and drain device drain port, cleaning can be performed very easily and reliably with almost no obstacles.
In the invention according to claim 7, since the arc guide portion is provided, the release wire is greatly bent along the arc guide in the drain plug main body, and bending that causes bending even when stress is applied to the release wire does not occur. For this reason, it is possible to make it difficult to cause breakage of the release wire such as buckling.
The invention according to claim 8 can specifically show a structure in which the drain plug main body and the release wire end are connected in a detachable manner.
Furthermore, in the invention described in claim 8, when the valve member is removed, there is no member such as a support member at the tank body drain port and the drainage device drain port.

Next, the screw member 16 that connects the drain plug body 4 and the lever mechanism member 13 is unscrewed, the screw member 16 and the lever member 13a are removed, and the release wire 9 and the drain plug body 4 are connected. Is released. The screw member 16 and the lever mechanism member 13 are pulled up from the tank body drain port 1 into the bathtub B. In this way, the drain plug body 4 side is in a state as shown in FIG.
Next, the fitting between the support mechanism portion 9d and the operation portion main body 8 is released, and the release wire 9 is pulled up from above the connection adapter 14. (Although part of the configuration and shape of the operation unit is different, the operation unit side is in a state substantially similar to that in FIG. 6).
The members are taken out by these procedures, the members are exchanged as necessary, and the remote-operated drain plug device is assembled again by the reverse procedure. That is, the release wire 9 is inserted from above the connection adapter 14, and the tip is disposed in the drain plug body 4 through the guide tube 15. The end of the release wire 9 is again sandwiched between the connection fixing portion 29 and the lever mechanism member 13, and the lever mechanism member 13 is fixed to the drain plug body 4 with the screw member 16, so that the end of the release wire 9 is connected to the drain plug body 4. Secure the connection. Further, the valve member 6 and the eye plate member 6e are disposed in the drainage device drainage port 3 and the button member 22 is connected to the release wire 9 to complete the replacement of the remote-operated drainage plug device.
