Description

  The present invention relates to a remote-operated drain plug device that remotely opens and closes a drain outlet provided on the bottom surface of a tank body such as a wash basin, a sink, and a bathtub. The present invention relates to a mounting structure of an operation unit of the apparatus and a positioning jig used for the construction.

  Conventionally, in the present invention, a drainage device provided with a drain outlet is provided on the bottom surface of a tank body such as a wash basin, a sink, and a bathtub in order to discharge wastewater to the sewage side. Among these, the drainage device that can open and close the drainage port by operating the operation unit provided particularly in a place away from the drainage port is particularly called a remotely operated drainage plug device. A first conventional example of a remotely operated drain plug device will be described below with reference to FIG.

The remote control type drain plug device of the first conventional example adopting the operation unit illustrated in FIG. 38 includes a drain plug body, a valve member, a valve support member, a release wire, an operation unit, an elbow member described below. Being done.
The drain plug body is a substantially cylindrical member that forms a drain port therein, and has a male screw portion on the outer surface thereof.
The valve member includes a disc-shaped valve body that closes the drain port and a fitting portion provided at the center of the lower surface of the valve body.
The support member is a member that is housed and fixed in the drain port, and is housed and fixed in the drain port in a state in which an end portion of a release wire described below is connected and fixed.
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 (not shown) that urges the inner wire toward the operating portion side.
The elbow member includes an opening provided with a female threaded portion that is screwed with a male threaded portion of the drain plug body, a discharge port for discharging wastewater flowing from the drainage port to the sewage side, and an insertion tube that communicates the release wire. Prepare.
The operation unit includes an operation unit main body, a nut member, an operation shaft support unit, and a button member described below.
The operation unit main body has a substantially cylindrical shape. The outer surface of the upper end portion of the cylindrical shape has a flange protruding continuously outward along the periphery, and the inner surface of the lower end portion of the cylindrical shape extends along the periphery. In this way, projecting portions that project continuously inward are provided. Moreover, it is a side surface of the operation part main body, Comprising: The external thread part is provided under the collar part.
The nut member includes a female screw portion that is screwed with a male screw portion of the operation portion main body.
The operation shaft support part is a cylindrical member, and one end of the outer tube of the release wire is connected to the lower end portion of the operation shaft, and an operation shaft with the lower end abutting on the inner wire is provided therein. Prepare. In addition, a mechanism called a thrust lock mechanism that functions by utilizing a return spring of a release wire at the time of completion of construction is provided inside the operation shaft support portion. Each time the thrust lock mechanism is pushed into the operating shaft from above, the operating shaft is moved forward (lowered), fixed / unlocked, and urged by the inner wire of the release wire to move backward (up). It works to repeat.
The button member is a disk-shaped member having an outer diameter slightly smaller than the inner peripheral surface of the operation unit main body, and includes a cylindrical portion at the center of the lower surface, and this cylindrical portion is fitted to the tip of the operation shaft. It is comprised as follows.
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 has a drain plug mounting hole for mounting a drain plug on the bottom surface, and a through hole for mounting an operation portion on the periphery of the upper opening.

When attaching the remote-operated drain plug device configured as described above to a bathtub that is a tank body, first, the drain plug body and the elbow member are screwed together via the peripheral edge of the drain plug mounting hole provided in the bathtub, etc. Attach and fix the drain plug body and elbow member to the plug mounting hole.
Next, the operation member main body is inserted into the through hole provided at the upper edge of the bathtub, and the nut member is operated from below with the nut lower surface in contact with the upper peripheral surface of the through hole. The operation unit main body is attached and fixed to the through hole by being screwed to the main body and holding the periphery of the through hole between the flange portion and the nut member.
Furthermore, after connecting the release wire to the operation shaft support member, the release shaft is inserted into the operation portion main body from the valve shaft side, and the operation shaft support portion is housed and fixed in the operation portion main body.
Further, after the tip of the release wire is inserted into the insertion tube of the elbow member, the release wire is pulled up from the drain outlet to the inside of the bathtub while using a jig such as radio pliers.
From this state, the end of the release wire is connected to the support member, and the support member is attached and fixed in the drain outlet. Thereafter, the valve shaft portion at the end of the inner wire is fitted into the fitting portion of the valve member.
Further, the button member is fitted to the operation shaft, and the installation of the remote control type drain plug device is completed.

When using the remote control type drain plug device according to the first conventional example, first, the button member of the operation unit is operated to close the drain port, that is, the inner wire of the release wire is on the operation unit side. The valve member moves backward and the valve member is lowered. 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 maintained and fixed by a thrust lock mechanism.
From this state, when the button member is pushed in again and the operation shaft of the thrust lock mechanism is released from the fixed state, the inner wire retracts toward the operation 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.

According to the remote control type drain plug device of the first conventional example, a seam portion is generated between the wall surface provided with the through hole to which the operation portion is attached and the operation portion main body, particularly the collar portion.
The material of the heel part and the inner surface of the tank body are often different, resulting in a difference in color tone and texture, resulting in poor design. Further, the seam portion is unevenness that is unnecessary in terms of design, and it is not a good-looking thing, and the design is also deteriorated in this respect.
In addition, when the drainage in the tank touches the joint, the drainage remains as it is due to surface tension, and when the drainage evaporates, dirt or dust in the drainage adheres. In addition, there is a problem that the end portion of the joint portion has a small step, it is difficult to insert a brush or the like, and the cleaning property is extremely deteriorated.

  On the other hand, the operation part main body is attached below the opening of the through hole, and from the front side of the tank body, only the button member is exposed from among the members of the operation part, and at least the flange part is provided from the front side of the tank body. The so-called flange-less method has been studied (when the flange is removed from the front side of the tank body, and there is a flange part on the back side of the tank body that is not visible to the user. However, if the flange is not visible from the front side of the tank body, it is called flangeless). For example, as shown in Patent Document 2, as in the second conventional example often used for a washstand or the like, a state in which a bar-shaped button member always protrudes from a through-hole regardless of opening and closing of a drain outlet. By simply attaching the operation unit body to the back surface of the periphery of the through hole, the operation unit of the remote control type drain plug device can be made flangeless without any trouble.

JP 2002-88553 A Japanese Patent Application Laid-Open No. 2008-240258 (Second Example)

However, in the remote-operated drain plug device that is often used in bathtubs and the like as in the first conventional example, it is flangeless by simply attaching the operation unit body from below the operation unit for the following reasons. Could not be done. For ease of explanation, the following reasons 1. Throughout reason 3, unless otherwise specified, the expression related to “the position of the front surface of the button member” is “the drain is closed and the user is performing some operation on the remote-controlled drain plug device”. Reason for indicating the position of the front surface of the button member in the absence of In a bathtub, the operation part of the remote-operated drain plug device often arranges the operation part on a part of the bathtub, particularly on the flat end surface of the opening periphery of the bathtub. By the way, in a bathtub, especially a residential bathtub, in order to keep the temperature of the bath water inside the bathtub, in most cases, the opening of the bathtub is covered with a bath lid. For this reason, if the front side surface of the button member protrudes from the front side surface of the periphery of the through hole, the button member is flush with the upper surface of the flange portion of the operation unit main body due to the weight of the bath lid when the bath lid is put on. As a result, there is a problem that the remote-operated drain plug device is accidentally activated to open the drain port, and the bath water is discharged. For example, if you place the button member of the operation unit on the part where the button member does not touch even if you cover the bath lid, such as inside the bathtub, you can prevent malfunction due to covering the bath lid, but in this way, Unnecessary unevenness due to the button member in the bathtub gives discomfort to the user of the bathtub, and further, the user of the bathtub leans against the wall on the side of the button member while taking a bath or stretches the body In doing so, there was a problem that the button member was touched and the button member was pushed in, the remote-operated drain plug device was activated to open the drain port, and the bath water was discharged. In addition, the remote-operated drain plug device itself was originally invented based on the desire to open and close the drain opening without touching the drainage accumulated inside the tank body. Therefore, it can be said that placing the operation part inside the tank body in which the wastewater is accumulated is a tip-over.
Reason 2 Reason 1 above. As a method for avoiding the problem described in the above, the position of the front surface of the button member is adjusted to the position of the front surface of the periphery of the through hole by adjusting the length of the button member or the operation shaft at the design stage. If it is possible to make the position substantially the same as the position, that is, substantially the same plane, the above-described reason 1. Such problems can be avoided. However, the thickness of a tank body such as a bathtub varies depending on the goods and is not constant (many is between about 4 millimeters and 10 millimeters). The same applies to a wall surface provided in the vicinity of the tank body other than the tank body. For this reason, for example, when a remote-operated drain plug device designed to have a wall surface with a through hole for attaching an operation portion as 10 millimeters is attached to a tank body with a wall surface thickness of 4 millimeters, the surface on the front side of the button member 6 mm protrudes from the surface on the front side of the peripheral edge of the hole and is not substantially the same surface. The following problems arise. On the contrary, when the remote-operated drain plug device designed to have a wall surface with a through hole for attaching the operation part as 4 mm is attached to a tank body having a wall thickness of 6 mm, the surface on the front side of the button member is a through hole. 2. It is arranged in a recessed part of 6 mm from the surface on the front side of the peripheral edge and is not substantially the same surface, and will be described later. The following problems arise.
In order to avoid the above problems, designing and manufacturing the operation unit members such as the drainage device body for each type of tank body will result in an extremely wide variety and small lot production, which is a reality in terms of manufacturing cost and material management. Not right. In fact, depending on the finishing state when opening the through hole in the tank body, there may be individual differences in the wall thickness of the periphery of the through hole even with the same type of tank body. By adjusting the shape, it is difficult to make the position of the surface on the front side of the button member substantially the same as the position of the surface on the front side of the periphery of the through hole, that is, substantially the same surface.
Reason 3. Reason 1 above. As a method for avoiding the problem described in the above, the length of the button member or the operation shaft is adjusted at the design stage, and the position of the front surface of the button member is set to be larger than the position of the front surface of the peripheral edge of the through hole. A method of making the position depressed is conceivable. For example, when the wall surface of the tank body to which the operation unit is attached is 4 mm, the position of the surface on the front side of the button member is designed to be recessed by about 1 mm from the position of the surface on the front side of the periphery of the through hole. In the remote control type drain plug device, even if the operation part is attached to the through hole provided on the wall surface having a wall thickness of 10 millimeters, the button member becomes a recessed portion of 7 millimeters from the surface on the front side of the tank body. However, the position of the surface of the button member on the front side is the same as that of the surface of the surface of the through hole on the front side. Thus, regardless of the thickness of the wall surface of the through-hole, it is possible to design the product so that the surface on the front side of the button member is always depressed more than the position of the surface on the front side of the periphery of the through-hole. It is. Also, with this configuration, the remote-operated drain plug device will not malfunction due to a bath lid on the bathtub or touching the user's body, and the functional problem is solved. However, such a configuration in which the surface on the front side of the button member is always depressed relative to the position on the front side of the peripheral edge of the through hole is extremely poor in design because a recess is formed on the plane. Furthermore, drainage and dust accumulate on the button member in the through hole, and the hygiene as well as the appearance deteriorates. In addition, the inner peripheral surface of the through hole and the peripheral portion of the front surface of the button member are corners, which causes a problem that it is difficult to insert a brush or the like and the cleaning property is extremely deteriorated. As a result, the design, cleanability, and hygiene are worse than those of the first conventional example, and the problem is far from being solved.

  The present invention has been made in view of the above-described problems. In the conventional example, the surface on the front side of the operation portion needs to be substantially the same as the surface on the front side of the periphery of the through hole. In a remote-operated drain plug device, there is no malfunction even if the bathtub is covered with a bath lid etc. while achieving the flange-less operation part, and in terms of design, cleaning and hygiene The present invention provides a remote-operated drain plug device that is improved over conventional products.

It is adjusted at the design time so as to be substantially the same plane.

The remote control type drain plug device of the first embodiment of the present invention configured as described above is constructed and attached to the bathtub B which is a tank body as follows. Although not described in detail, even in the case where there is no particular description, watertight connection is performed by using packing or the like at a portion where watertightness is required at a connection portion between members.
First, in a factory or the like, a connecting member is attached and fixed to the tank body drain port 12. In attaching the tank body outlet 12 and the connecting member, the connecting member is disposed below the bathtub B, and then the tank body outlet 12 and the drainage apparatus outlet 15 are arranged concentrically using a jig or the like. Then, the screw member V is screwed into the screw hole portion 13 through the opening of the flange portion 16, and the connecting member is attached and fixed from below the bathtub B.
Also, a part of the remote-operated drain plug device is assembled at the same factory according to the following procedure.
The operation shaft support 2 is connected to the end of the release wire 11 on the side where the valve shaft 11c is not provided, and then the release wire 11 is inserted into the operation portion main body 1 from above so that the operation shaft support 2 is locked. The step portion 28 is engaged with the locking teeth 25 of the operation portion main body 1. At this time, the operation shaft support portion 2 is disposed so that the locked stepped portion 28 is engaged with the locking teeth 25 and is located at the uppermost position of the operation portion main body 1.
Next, after inserting the ring member 29 into the release wire 11, the release wire 11 is inserted from the inside of the insertion tube 19 of the drain plug main body 8, and the end of the release wire 11 is arranged inside the drain plug main body 8. Further, the end of the release wire 11 is pulled up, the end of the release wire 11 is connected and fixed to the support member 9, and then the support member 9 is fitted and fixed to the uneven portion 20 of the drain plug body 8.

Since work on these bathtubs B and remote-controlled drain plug devices is performed in the factory, a large work space can be taken, a work table that facilitates the work is installed, and the work is performed in an environment where equipment is available. be able to. Furthermore, since the assembly of the remote-operated drain plug device itself is not connected to the bathtub B, members such as the drain plug main body 8 and the operation unit main body 1 are placed at hand so that the operator can easily see and work. In addition, the work can be performed while being arranged at a position / angle at which it is easy to work, or moved / rotated. For this reason, the assembly operation of the remote-operated drain plug device up to this stage can be made much easier than in the conventional example. In this manner, the drain plug body 8 side of the remote-controlled drain plug device of the first embodiment is assembled to the state shown in FIG.

Next, the bathtub B and the remote-operated drain plug device assembled up to the stage of paragraph 0025 and other members are carried into the construction site. At the construction site, the following operations are performed on the drain plug body 8 side and the operation unit side, respectively.
On the drain plug body 8 side, the lower end portion of the connection member is inserted into the opening on the upper surface of the drain plug body 8, and the drain plug side engagement portion 17 of the drain plug body 8 and the drain plug side engagement portion 17 of the connection member. And abut. Further, the drain plug side C-shaped ring 21 is engaged with both drain plug side engaging portions 17 to connect and fix the drain plug body 8 and the connection member.
By making such a connection, the connecting member and the drain plug body 8 are always at the same height position in the height direction, that is, the operation part side engaging part 32 of the operation part body 1 and the operation part of the connection adapter. It is connected to a height position where the side engaging portion 32 comes into contact. For this reason, the drain plug main body 8 is arranged at a fixed height position with respect to the water stop surface 16a provided on the connection member.

On the operation part side, the contact adjusting part 7 b of the positioning jig 7 is inserted into the through hole H. At this time, as shown in FIG. 5, it is inserted until the lower surface of the contact rib 7a contacts the upper surface of the periphery of the through hole H.
From this state, the operation unit is disposed below the through hole H while the engagement adjusting unit 7 b is inserted into the operation unit main body 1. At this time, the contact adjusting portion 7b of the positioning jig 7 functions as a guide for preventing the operation portion main body 1 from being installed in a state where the operation portion main body 1 is inclined or displaced with respect to the upper surface of the periphery of the through hole H. Further, when the operation portion main body 1 is raised, the upper surface of the operation shaft support portion 2 other than the operation shaft 2a comes into contact with the lower end of the contact adjusting portion 7b as shown in FIG. When the operation unit main body 1 is further raised from this state, the slit portion 24 of the operation unit main body 1 is expanded in diameter, and the engagement between the locked stepped portion 28 and the locking teeth 25 is shifted up and down by one step. The shaft support 2 lowers the position with respect to the operation unit main body 1. When the operation unit body 1 is further raised, the operation shaft support unit 2 is lowered with respect to the operation unit body 1, and finally, as shown in FIG. The upper surface of the portion 23 comes into contact with the surface on the back side of the periphery of the through hole H. When this state is reached, the ring member 29 is pushed up and fitted into the groove portion of the operation portion main body 1. Thereby, the diameter of the slit part 24 of the operation part main body 1 cannot be increased, and the operation shaft support part 2 cannot be moved in the vertical direction with respect to the operation part main body 1 and is fixed.
At this time, the position of the operation shaft support portion 2 with respect to the operation portion main body 1 is determined by the positioning jig 7 so that the front side surface of the button member 3 becomes substantially the same surface as the front side surface of the periphery of the through hole H when the construction is completed. Adjusted and fixed so that it is in position.
That is, in this embodiment, the position adjusting mechanism including the locking tooth 25 and the locked stepped portion 28 is positioned between the operating portion main body 1 and the operating shaft support portion 2 with respect to the axial direction of the operating shaft 2a. This is a remote-operated drain plug device with the function of adjusting and fixing the pressure. Further, in this embodiment, the position adjustment by the position adjustment mechanism is performed in units of a constant pitch of 1 millimeter since the locking teeth 25 and the locked stepped portion 28 are configured in the vertical direction in units of 1 millimeter. Configured to be done.
In addition, the position adjustment of the button member 3 in the present embodiment is performed in units of 1 millimeter which is the pitch between the locking tooth 25 and the locked stepped portion 28. For this reason, “substantially the same surface” as used in this embodiment means that there is no step between the front side surface of the button member 3 and the front side surface of the periphery of the through hole H, and the height difference between them is within 1 mm. Say the state. Further, in the present embodiment, from the viewpoint of design, the position of the operation shaft support portion 2 with respect to the operation portion main body 1 so that the button member 3 protrudes upward from the peripheral edge of the through hole H in the case of being substantially flush. It is assumed that the surface on the front side of the button member 3 is not disposed below the surface on the front side of the periphery of the through hole H.
From this state, after screwing the screw member V into the screw hole portion 13 on the through hole H side through the opening of the flange portion 23 of the operation portion main body 1, and fixing the operation portion main body 1 from below the bathtub B, The positioning jig 7 is pulled out from the through hole H.
Further, from the front side of the bathtub B, the valve member 10 is fitted and fixed to the valve shaft portion 11c, and the button member 3 is fitted and fixed to the operation shaft 2a, so that the construction of the remotely operated drain plug device as shown in FIG. 1 is completed. To do.

The remote control type drain plug device of the first embodiment constructed as described above can open and close the drainage device drain port 15 by remote operation by operating as follows.
First, as shown in FIG. 1, the valve member 10 is lowered, and the contact portion 22 of the valve member 10 is in contact with the water stop surface 16a. The state of the operation unit at this time is as shown in FIG. When a push operation is applied to the button member 3 of the operation unit in this state, the elastic member 4 inside the button member 3 first contracts by about 1.5 millimeters as shown in FIG. In the contraction stage of the elastic member 4, the operation shaft 2a does not operate at all. The state in which the operating shaft 2a does not operate when the button member 3 is pushed and the elastic member 4 only contracts is hereinafter referred to as “empty pressing”. When the elastic member 4 is sufficiently contracted and cannot be contracted any more, the operation shaft 2a is pushed in such a manner that it is pushed by the button member 3 through the elastic member 4 as shown in FIG. Thereby, the operation shaft 2a protrudes toward the inner wire 11b, and accordingly, the inner wire 11b protrudes toward the drainage device drainage port 15 with respect to the outer tube 11a, pushes up the valve member 10 and contacts the contact portion 22 from the water stop surface 16a. Are opened, and the drainage drainage 15 is opened as shown in FIG. When the user finishes pushing the button member 3, the operation shaft 2 a is fixed in this state by the thrust lock mechanism, and the open state of the drainage device drainage port 15 is maintained. Further, the elastic member 4 is also released, and as shown in FIG. 12, the elastic member 4 returns from the contracted state to an extended state by about 1.5 millimeters.
When the pushing operation is again applied to the button member 3 of the operation unit from this state, as shown in FIG. 11, the elastic member 4 is sufficiently contracted after being pushed idle by about 1.5 millimeters, and can be further contracted. The operation shaft 2a is pushed in such a way as to be pushed by the button member 3. As a result, the thrust lock mechanism operates, and the fixing of the operation shaft 2a by the thrust lock mechanism is released. For this reason, when the user finishes pushing the button member 3, the inner wire 11 b is retracted toward the operation portion due to the weight of the valve member 10 and the action of the return spring, and the valve member 10 is lowered to contact the contact portion 22. Returning to the state of FIG. 1 where the water stop surface 16a comes into contact and the drainage device drainage port 15 is closed. Further, the elastic member 4 is also released, and returns to the state shown in FIG.
Thereafter, by repeating the same operation, the drainage device drainage port 15 can be opened / closed remotely, and the wastewater in the bathtub B can be discharged at the time of opening.

  In the remote control type drain plug device of the first embodiment configured as described above, the position adjustment is performed between the operation unit main body 1 and the operation shaft support unit 2 while using the positioning jig 7. For this reason, as shown in FIG. 8, no matter how the wall thickness around the through hole H changes, when the construction is completed, the front side surface of the button member 3 is replaced with the front side surface around the through hole H. It can be almost flush.

Further, the position adjustment of the button member 3 in the present embodiment is performed in units of 1 millimeter which is the pitch between the locking tooth 25 and the locked stepped portion 28. For this reason, “substantially the same surface” in this embodiment means that there is no step between the front side surface of the button member 3 and the front side surface of the periphery of the through hole H, and the difference in height between the two is within 1 mm. It shows the state. In the present embodiment, from the viewpoint of design, the position of the operation shaft support portion 2 with respect to the operation portion main body 1 is adjusted so that the button member 3 protrudes from the periphery of the through hole H when the surface is substantially flush. Do it. For this reason, when construction is completed, the surface on the front side of the button member 3 is completely the same as the surface on the front side of the periphery of the through hole H, protrudes upward by about 1 millimeter, or between them. It becomes such a state. However, for the following reason, in this embodiment, the functional and design problems in the case where the front side surface of the button member 3 protrudes from the front side surface of the periphery of the through hole H are solved.
As a functional problem due to the button member 3 protruding beyond the periphery of the through-hole H, the reason for paragraph 0010 is as follows. Since the button member 3 protrudes more than the periphery of the through-hole H as described in 1., when the user of the bathtub B touches the button member 3 accidentally, the button member 3 touches the button member 3 Is pushed until it is flush with the periphery of the through-hole H, resulting in a problem that the remote-operated drain plug device malfunctions. However, in the remote control type drain plug device of the present embodiment, the elastic member 4 is incorporated in the button member 3, and the button member 3 is pushed by about 1.5 millimeters. In the present embodiment, the height difference is up to 1 mm even when the button member 3 protrudes most from the periphery of the through hole H because of the vertical pitch relationship between the locking teeth 25 and the locking steps. Therefore, the operation shaft 2a does not operate unless the button member 3 is pushed further downward by 0.5 millimeters from the periphery of the through hole H as shown in FIG. 10, and naturally the remote control type drain plug device does not operate. . Thus, in this embodiment, the length of the idle pressing between the button member 3 and the operation shaft 2a is slightly larger (0.5 mm) than one unit of the position adjustment pitch of the position adjustment mechanism. As a result, when the button member 3 is only pushed in until it is completely flush with the periphery of the through hole H, the button member 3 is surely idled and the remote-operated drain plug device malfunctions. The configuration is to prevent this.
As a design problem due to the button member 3 protruding beyond the periphery of the through-hole H, the front side surface of the button member 3 is a flat end surface, and therefore the front side surface of the button member 3 is the same flat end surface. There is a problem that the design aesthetics are better when the periphery of a certain through-hole H and thus the flat surface of the upper edge of the bathtub B are completely flush, and the protrusion of the button member 3 impairs this aesthetics. .
However, when viewed from the entirety of the bathtub B and the bathroom, the length of 1 mm is only a very small length. For example, the height width from the floor of the bathroom to the upper end surface of the bathtub B is called “stretching height”, and this straddling height is usually about 360 mm to 450 mm, and 1 mm is this straddling height. It is only a little less than 0.3 percent. As long as the bathtub B or bathroom is normally used, the button member 3 can only be seen from above or obliquely above, and the protruding width of the button member 3 is negligible when viewed from the entire bathtub B or bathroom. Therefore, it is almost impossible for the user to recognize a protrusion of 1 mm or less of the button member 3. In particular, in this embodiment, an arc having a radius of 1 mm is provided on the periphery of the button member 3, and a chamfer 14 is also provided on the periphery of the through hole H, and the outer periphery of the button member 3 and the through hole H are formed by the arc and chamfer 14. It is difficult to recognize the presence or absence of a step between the button member 3 and the periphery of the through-hole H at the boundary of the periphery of the button, and the height difference between the upper surfaces of the button member 3 and the periphery of the through-hole H is 1 millimeter or less. In combination with the idea that it only occurs, the button member 3 feels as if it is completely flush with the periphery of the through hole H, so that the design aesthetics are arranged.
The sense that “the front side surface of the button member 3 is completely flush with the peripheral edge of the through hole H, which is the same flat end surface, and thus the flat surface of the upper edge portion of the bathtub B, is better in design.” Is subjective only. For this reason, it is considered that the user may prefer that the button member 3 protrude sufficiently from the periphery of the through hole H.

Next, a second embodiment of the present invention will be described with reference to the drawings. The remote-operated drain plug device according to the second embodiment of the present invention shown in FIGS. 14 to 24 is an embodiment corresponding to claim 1, claim 3, claim 5, and claim 8 to claim 11.

For this reason, when construction is completed, the surface on the front side of the button member 3 is in any state from the same state as the surface on the front side of the periphery of the through hole H to a state protruding upward by about 1 millimeter. . However, due to the same actions and effects as described in the first embodiment described in Paragraph 0030, in this embodiment, the front side surface of the button member 3 is functional when protruding from the front side surface of the periphery of the through hole H. And design problems are solved.
Further, in the remote-operated drain plug device of the third embodiment configured as described above, when the valve member 10, the button member 3, the arc guide member, the release wire 11 or the like is damaged, it is described in paragraph 0036. The member can be removed in the same procedure as the remote-operated drain plug device of the second embodiment and replaced with the same component without damage.

Next, a fourth embodiment of the present invention will be described with reference to the drawings. The remote-operated drain plug device of the fourth embodiment of the present invention shown in FIGS. 32 to 36 is an embodiment corresponding to claim 6, and is described below. It comprises a member, a drain plug body 8, a support member 9, a valve member 10, a release wire 11, an operation unit, and a guide tube 30.
Of these, the bathtub B, the connecting member, the drain plug main body 8, the support member 9, the valve member 10, and the release wire 11 are the same as the respective members of the first embodiment described in paragraph 0024, and therefore description thereof is omitted.
The operation unit includes an operation unit main body 1, an operation shaft support unit 2, and a button member 3 described below.
The operation section main body 1 includes an adapter member 1a attached to the back surface of the through hole H, a support section storage member 1b connected to the adapter member 1a from below, and a drain plug side C-shaped ring 21.
More specifically, the adapter member 1a is a substantially cylindrical member whose inner diameter is substantially the same as the inner diameter of the through-hole H, and in which a plurality of openings for inserting the screw member V are provided above. The unit 23 is provided.
The support portion storage member 1b is a substantially cylindrical member, and includes an operation portion side engagement portion 32 on the outer peripheral surface of the upper end portion, and the inside of the opening at the upper end is a lower portion of the adapter member 1a. It is configured to be stored. Further, the operation shaft support portion 2 is configured to be detachably stored and fixed inside the support portion storage member 1b.
The drain plug side C-shaped ring 21 is a C-shaped member having a U-shape that opens inward in cross section, and is provided on the adapter unit 1a and the support unit storage member 1b. It is a member that engages with the joint portion 32 to connect and fix the adapter member 1a and the support portion storage member 1b.
The operation shaft support portion 2 is a cylindrical member, and one end of the outer tube 11a of the release wire 11 at the time of completion of construction is connected to the lower end portion of the operation shaft support portion 2, and the lower end contacts the inner wire 11b. An operating shaft 2a is provided. The upper end of the operation shaft 2a is provided with a protrusion 27 along the periphery on the upper side surface. The operation shaft 2a has an adapter member whose height at the upper end of the operation shaft 2a is closed when the construction is completed and the user does not perform any operation on the remote-controlled drain plug device. It is designed to be in the same position as the upper end of 1a.
Further, a mechanism called a thrust lock mechanism that functions by utilizing the return spring of the release wire 11 when construction is completed is provided inside the operation shaft support portion 2. Each time the thrust lock mechanism is pushed into the operation shaft 2a from above, the operation shaft 2a is moved forward (lowered) to be fixed / released, and is biased by the inner wire 11b of the release wire 11 to move backward ( )).
The button member 3 is a bottomed cylindrical member having an outer diameter slightly smaller than the inner peripheral surface of the adapter member 1a, and is constructed so that the lower part is an opening. The cylindrical portion 3a slides up and down in a state in which the operation shaft 2a is accommodated, and engages with the protrusion 27 of the operation shaft 2a at the inner peripheral portion of the lower end portion, so that a relatively strong force (occurs in normal use). And a retaining portion 3b that does not come off the operation shaft 2a unless the button member 3 is lifted with a force that does not occur unless the button member 3 is intentionally removed. As described above, in this embodiment, the protrusion 27 of the operation shaft 2a and the retaining portion 3b of the button member 3 constitute a locking mechanism that prevents the button member 3 from jumping out of the operation portion. Become. Further, the button member 3 can be pushed into the operation shaft 2a for the first time when the front surface of the button member 3 is pushed up to a position of 2 mm from the upper end of the operation shaft 2a. It is composed (it is idle until it reaches its height position).
In addition, an elastic member 4 that extends and contracts in the vertical direction is formed of a spring at a portion between the button member 3 and the operation shaft support portion 2. The elastic member 4 is repelled by the weight of the button member 3 and pushes the button member 3 up to an upper limit, that is, a position where the retaining portion 3b and the projecting portion 27 come into contact with each other. Is performed, it is configured to easily contract in the vertical direction.
When the button member 3 is pushed up to the upper limit, the front surface of the button member 3 is positioned approximately 25 millimeters above the upper end of the adapter member 1a, that is, the back surface of the periphery of the through hole H. It is made up of.
The guide tube 30 is a long cylindrical member made of vinyl chloride having rigidity in the axial direction and flexibility in the side surface direction, one end being the insertion tube 19 of the elbow member and the other end being the support portion storage member. Each is connected to the lower end portion of 1b.

The remote control type drain plug device of the fourth embodiment of the present invention configured as described above is constructed and attached to the bathtub B which is a tank body as follows. Although not described in detail, even in the case where there is no particular description, watertight connection is performed by using packing or the like at a portion where watertightness is required at a connection portion between members.
First, in a factory or the like, the connecting member is attached to the tank body drain 12 and the adapter member 1a is attached and fixed to the through hole H, respectively. In attaching the tank body outlet 12 and the connecting member, the connecting member is disposed below the bathtub B, and then the tank body outlet 12 and the drainage apparatus outlet 15 are arranged concentrically using a jig or the like. Then, the screw member V is screwed into the screw hole portion 13 through the opening of the flange portion 16, and the connecting member is attached and fixed from below the bathtub B. Moreover, in the connection between the through hole H and the adapter member 1a, the adapter member 1a is arranged below the bathtub B, and then the through hole H and the adapter member 1a are arranged concentrically using a jig or the like. The screw member V is screwed into the screw hole portion 13 through the opening of the flange portion 23, and the adapter member 1a is attached and fixed from below the bathtub B.
Also, a part of the remote-operated drain plug device is assembled at the same factory according to the following procedure.
First, one end of the guide tube 30 is connected to the insertion tube 19 of the drain plug main body 8, and the other end is connected to the lower end of the support housing member 1b.
Next, after connecting the operation shaft support 2 to the end of the release wire 11 on the side not provided with the valve shaft 11c, the release wire 11 is inserted into the support housing member 1b from above, and finally the operation shaft. The support part 2 is stored and fixed on the support part storage member 1b. At this time, the tip of the release wire 11 is disposed inside the drain plug main body 8 via the guide tube 30 and the insertion tube 19.
Further, the end of the release wire 11 is pulled up, the end of the release wire 11 is connected and fixed to the support member 9, and then the support member 9 is fitted and fixed to the uneven portion 20 of the drain plug body 8.
Since work on these bathtubs B and remote-controlled drain plug devices is performed in the factory, a large work space can be taken, a work table that facilitates the work is installed, and the work is performed in an environment where equipment is available. be able to. Furthermore, since the assembly of the remote-operated drain plug device itself is not connected to the bathtub B, members such as the drain plug main body 8 and the operation unit main body 1 are placed at hand so that the operator can easily see and work. In addition, the work can be performed while being arranged at a position / angle at which it is easy to work, or moved / rotated. For this reason, the assembly operation of the remote-operated drain plug device up to this stage can be made much easier than in the conventional example. In this way, the drain plug body 8 side of the remote control type drain plug device of the fourth embodiment is assembled up to the state of FIG. 34 (the drain port side is the same as the first embodiment except for the presence or absence of the guide tube. Omitted because there are.)

Next, the bathtub B and the remote-operated drain plug device assembled up to the stage of the above paragraph 0043 and other members are carried into the construction site. At the construction site, the following operations are performed on the drain plug body 8 side and the operation unit side, respectively.
On the drain plug body 8 side, the lower end portion of the connection member is inserted into the opening on the upper surface of the drain plug body 8, and the drain plug side engagement portion 17 of the drain plug body 8 and the drain plug side engagement portion 17 of the connection member. And abut. Further, the drain plug side C-shaped ring 21 is engaged with both drain plug side engaging portions 17 to connect and fix the drain plug body 8 and the connection member.
By making such a connection, the connecting member and the drain plug body 8 are always at the same height position in the height direction, that is, the operation part side engaging part 32 of the operation part body 1 and the operation part of the connection adapter. It is connected to a height position where the side engaging portion 32 comes into contact. For this reason, the drain plug main body 8 is arranged at a fixed height position with respect to the water stop surface 16a provided on the connection member.

On the operation part side, the lower end portion of the adapter member 1a is inserted into the opening above the support part storage member 1b, and the operation part side engagement part 32 of the support part storage member 1b and the operation part side engagement of the adapter member 1a. The part 32 is brought into contact.
Furthermore, the operation part side C-shaped ring 35 is engaged with both operation part side engaging parts 32, and the adapter member 1a and the support part accommodating member 1b are connected and fixed.
Further, the valve member 10 is fitted to the valve shaft portion 11c and the button member 3 is fitted and fixed to the operation shaft 2a from the front side of the bathtub B, and the state as shown in FIG. 32 is obtained. Is completed.
With this configuration, when the drain is closed and the user is not performing any operation on the remote-controlled drain plug device, the front side surface of the button member 3 is the front side of the periphery of the through hole H. It protrudes from the surface. The specific degree of protrusion of the button member 3 is about 25 millimeters above the position of the back surface of the periphery of the through hole H. Therefore, if the thickness of the periphery of the through hole H is 4 millimeters, it is 21 millimeters. If the peripheral thickness is 10 mm, the front side surface of the button member 3 protrudes from the front side surface of the peripheral edge of the through-hole H by 15 mm.

The remote control type drain plug device of the fourth embodiment constructed as described above can open and close the drainage device drain port 15 by remote control by operating as follows.
First, the valve member 10 is lowered, and the contact portion 22 of the valve member 10 is in contact with the water stop surface 16a. When a pushing operation is applied to the button member 3 of the operation unit in this state, the button member 3 is first idle-pressed by the elastic member 4 inside the button member 3.
As described in paragraph 0042, in a state where the drain port is closed and the user has not performed any operation on the remote-controlled drain plug device, the operation shaft 2a is at the same position as the upper end of the adapter member 1a, and When the front surface of the button member 3 reaches a height of 2 millimeters from the upper end of the operation shaft 2a, it is possible to push the operation shaft 2a for the first time. Therefore, in the case of using the remote control type drain plug device of this embodiment in a general bathtub B having a thickness of 4 mm to 10 mm at the peripheral edge of the through hole H, the surface on the front side of the button member 3 is formed through the through hole H. As shown in FIG. 35, the button member 3 is idly pushed until it reaches a position 2 mm higher than the back side surface of the peripheral edge of the through hole H as shown in FIG. to continue.
When the front surface of the button member 3 reaches a position 2 millimeters higher than the upper end of the operation shaft 2a, the operation shaft 2a is pushed downward as shown in FIG. Thereby, the operation shaft 2a protrudes toward the inner wire 11b, and accordingly, the inner wire 11b protrudes toward the drainage device drainage port 15 with respect to the outer tube 11a, pushes up the valve member 10 and contacts the contact portion 22 from the water stop surface 16a. Are opened, and the drainage drainage 15 is opened. When the user finishes pushing the button member 3, the operation shaft 2 a is fixed in this state by the thrust lock mechanism, and the open state of the drainage device drainage port 15 is maintained. Further, since the elastic member 4 is also opened, the button member 3 returns to the state where the button member 3 is raised to the position where the retaining portion 3b and the projection 27 abut on the operation shaft 2a.
When a push operation is again applied to the button member 3 of the operation unit from this state, the operation is performed so that the front surface of the button member 3 is pressed to the state of FIG. The shaft 2a is pushed. As a result, the thrust lock mechanism operates, and the fixing of the operation shaft 2a by the thrust lock mechanism is released. For this reason, when the user finishes pushing the button member 3, the inner wire 11 b is retracted toward the operation portion due to the weight of the valve member 10 and the action of the return spring, and the valve member 10 is lowered to contact the contact portion 22. The water stop surface 16a comes into contact, and the drainage device drainage port 15 returns to the closed state. Further, since the elastic member 4 is also opened, the button member 3 returns to the state where the button member 3 is raised to the position where the retaining portion 3b and the projection 27 abut on the operation shaft 2a. Thereafter, by repeating the same operation, the drainage device drainage port 15 can be opened / closed remotely, and the wastewater in the bathtub B can be discharged at the time of opening.

In the present embodiment, when the drain port is closed and the user is not performing any operation on the remote-controlled drain plug device, the front side surface of the button member 3 is the front side of the periphery of the through hole H as described above. It protrudes from the surface. Specifically, the degree of protrusion of the button member 3 is 21 millimeters when the thickness of the peripheral edge of the through hole H is 4 millimeters, and 15 millimeters when the thickness of the peripheral edge of the through hole H is 10 millimeters. However, it will protrude from the surface on the front side of the periphery of the through-hole H. However, for the following reason, in this embodiment, the functional and design problems in the case where the front side surface of the button member 3 protrudes from the front side surface of the periphery of the through hole H are solved.
As a functional problem due to the button member 3 protruding beyond the periphery of the through-hole H, the reason for paragraph 0010 is as follows. Since the button member 3 protrudes more than the periphery of the through-hole H as described in 1., when the user of the bathtub B touches the button member 3 accidentally, the button member 3 touches the button member 3 Is pushed until it is flush with the periphery of the through-hole H, resulting in a problem that the remote-operated drain plug device malfunctions. However, in the remote-operated drain plug device of the present embodiment, the elastic member 4 is incorporated in the button member 3, and the button member 3 is idle-pressed until reaching a height position of about 2 millimeters from the back side surface of the periphery of the through hole H. It is configured to do. As described in paragraph 0010, the thickness of the tank body such as the bathtub B varies depending on the article, but since it is mostly between about 4 millimeters and 10 millimeters, as long as the bathtub B in this range is used, If the button member 3 is not further pushed in from the surface on the front side of the periphery of the through hole H, the operation shaft 2a does not operate, and naturally the remote-operated drain plug device does not operate.
Thus, in this embodiment, the button member 3 is idle-pressed until the surface on the front side of the button member 3 is the same as the surface on the front side of the peripheral edge of the through hole H or is pushed into the back side. Thus, the button member 3 is configured to push the operation shaft 2a for the first time when it has moved downward. In other words, when the button member 3 is only pushed in until it is completely flush with the periphery of the through-hole H, the button member 3 is surely pushed and the remote-operated drain plug device is prevented from malfunctioning. .
As a design problem due to the button member 3 protruding beyond the periphery of the through-hole H, the front side surface of the button member 3 is a flat end surface, and therefore the front side surface of the button member 3 is the same flat end surface. There is a problem that the design aesthetics are better when the periphery of a certain through-hole H and thus the flat surface of the upper edge of the bathtub B are completely flush, and the protrusion of the button member 3 impairs this aesthetics. .
However, the design aesthetics are based solely on the user's subjectivity. For this reason, it may be preferred by the user that the button member 3 protrudes more sufficiently than the periphery of the through hole H. Conceivable.
Further, for example, as described above, “the front side surface of the button member 3 is a flat end surface. Therefore, it is more desirable that the front side surface of the button member 3 is completely flush with the periphery of the through hole H that is the same flat end surface. The problem that “the aesthetic appearance is adjusted” is that the shape of the front surface of the button member 3 is not a flat end surface, but a shape that does not cause a sense of incongruity even if the button member 3 protrudes from the periphery of the through hole H, such as a semicircular shape or a truncated cone. Etc. can be easily solved.
In addition, since the extent of the protrusion of the button member 3 in this embodiment with respect to the periphery of the through hole H varies depending on the thickness of the periphery of the through hole H, there is no sense of unity. However, it seems that there is no particular design problem with respect to the lack of unity. This is because as long as the bathtub B is viewed individually, for most users, the design difference more than “the button member 3 protrudes from the periphery of the through hole H” does not occur. When comparing a plurality of bathtubs B side by side, it may be possible to notice a difference in the degree of protrusion. However, since it is not usual to arrange a plurality of bathtubs B side by side, The point that the degree of protrusion differs for each bathtub B is merely a difference that the user does not notice, and does not cause a problem.

  Further, in the remote-operated drain plug device of the fourth embodiment configured as described above, when the valve member 10, the button member 3, the arc guide member, the release wire 11 or the like is damaged, it is described in paragraph 0035. The member can be removed in the same procedure as the remote-operated drain plug device of the second embodiment and replaced with the same component without damage.
