Description

  The present invention relates to a drain plug device for opening and closing a drain plug provided in a tank body.

Conventionally, a drain plug device for opening and closing a drain plug provided in a tank body such as a bathtub by operating an operation unit similarly attached to the tank body is known (for example, Patent Document 1).
FIG. 1 is an explanatory view illustrating a drain plug device as a conventional technique. A drain plug mechanism 110 is attached to the drain port 104 formed on the bottom surface 101 of the bathtub 100. A push button as an operation part 121 for operating the drain plug mechanism 110 is attached to the flange part 103 supported by the side wall 102 of the bathtub 100. The operation unit 121 and the drain plug mechanism 110 are connected by a release wire 122. When the user operates the operation unit 121, the operation force is transmitted to the drain plug mechanism 110 via the release wire 122, and the drain plug is connected. It opens and closes. The periphery of the release wire 122 is covered with a guide tube 120.

As described above, when the operation portion 121 of the drain plug device is formed on the flange portion 103 of the bathtub 100, the following various problems may occur.
1stly, since the upper surface of the flange part 103 becomes non-flat by the presence of the operation part 121, a clearance gap arises between a bathtub and its cover, and when it sits down, it will receive discomfort. Secondly, when the bathtub 100 is installed in the bathroom, it is necessary to determine the direction of the bathtub 100 so that the operation unit 121 is located at a predetermined position, for example, the front side of the washing place in the bathroom. The degree of freedom decreases.

  In view of such an adverse effect, there is an apparatus disclosed in Patent Document 2 as an example in which the operation unit is provided other than the flange portion of the bathtub. In this example, the operation unit is attached to a bathroom wall.

JP 2012-2111449 A JP 2010-196331 A

However, as disclosed in Patent Document 2, it is not easy to attach the operation unit to a portion different from the bathtub body. In the drain plug device, it is not necessary to simply connect the drain plug and the operation unit so as to connect the electrical wiring. The operation force applied to the operation unit is mechanically transmitted via a release wire or the like. Need to be concatenated. In addition, even after the drain plug device is assembled, it must be disassembled for inspection and repair as appropriate.
Even if it tries to assemble in this way, depending on the part to which the operation unit is attached, it is difficult for the installer to visually recognize the drain plug device, or there is not enough space to insert a hand, Secure assembly could not be performed efficiently. This problem is the same for tanks other than bathtubs.
An object of this invention is to enable it to perform the assembly | attachment of the drain plug apparatus which provided the operation part other than the tank main body easily and reliably in view of this subject.

The present invention
In the drain plug device for opening and closing the drain plug provided in the tank body,
A tank body side drive mechanism for opening and closing a drain plug provided in the tank body;
A support portion for supporting the other end opposite to the drain plug of the tank body side drive mechanism at a predetermined position;
A decorative panel installed in or near the tank body;
An operation unit provided on the decorative panel, for a user to open and close the drain plug;
It is provided with the panel side drive mechanism provided in the said decorative panel, and transmitting the operating force applied to the said operation part to the said tank body side drive mechanism.

  In the present invention, the drive mechanism for opening and closing the drain plug is separated into a tank body side drive mechanism and a panel side drive mechanism provided on the decorative panel. Since the tank side drive mechanism can be attached before attaching the decorative panel, it can be attached easily and reliably without the decorative panel becoming an obstacle. In addition, when the decorative panel is assembled, the operation force from the operation unit can be transmitted to the tank body side drive mechanism by the panel side drive mechanism, so that the drive mechanism for opening and closing the drain plug can be easily completed. . Therefore, in the drain plug device, the operation unit can be provided on the decorative panel surface other than the tank body itself relatively easily.

In the present invention, the tank includes a bathtub, a washbasin, and the like.
The drain plug is often formed on the bottom surface of the tank body, but may be formed on other parts.
As the tank side drive mechanism, any known mechanism for opening and closing the drain plug can be applied. For example, as shown in FIG. 1, a mechanism that opens and closes by a pressing force applied to a release wire, a mechanism that uses a link instead of a release wire, a mechanism that opens and closes according to the rotation of a knob or the like instead of a pressing force, etc. Can be mentioned.
A support part is good also as a member which supports a tank body side drive mechanism to tank body itself. Moreover, it is good also as a member which supports a tank body side drive mechanism in the base for installing a tank body in a floor surface, etc., the room | chamber or other structure in which a tank body is installed.
The decorative panel includes not only those installed on the tank body itself but also those installed in the vicinity thereof. As what is installed in the vicinity, when a tank body is a bathtub, the wall surface of a bathroom, a floor surface, etc. are mentioned, for example.
The panel drive mechanism may be formed integrally with the operation unit, or may be formed as a separate member from the operation unit.
The panel side drive mechanism only needs to be able to transmit the operating force to the tank body side drive mechanism, and is not necessarily mechanically connected to the tank body side drive mechanism. For example, when the operation force is a pushing force, the end portion of the panel side drive mechanism may be simply arranged so as to face and contact the tank body side drive mechanism.

In the drain plug device of the present invention,
It is good also as a thing provided with the connection mechanism which connects the said tank body side drive mechanism and the said panel side drive mechanism.
By doing so, it becomes possible to transmit the operating force reliably and without waste.
As the coupling mechanism, various mechanisms for mechanically coupling the tank body side driving mechanism and the panel side driving mechanism can be used. For example, a mechanism that attracts by a magnetic force, and a concave portion and a convex portion that are respectively formed in both mechanisms. A fitting mechanism, a fastening member such as a screw connecting both mechanisms, and the like can be used. The coupling mechanism may be provided as a mechanism different from the tank body side driving mechanism and the panel side driving mechanism, or may be formed by being incorporated in these mechanisms.

  The connection mechanism may be a mechanism capable of connecting the tank body side drive mechanism and the panel side drive mechanism in conjunction with the attachment of the decorative panel. A connection mechanism connects a tank side drive mechanism and a panel side drive mechanism in the state which attached the decorative panel. Therefore, it is preferable to use a mechanism that can be automatically connected in conjunction with attaching the decorative panel, such as a mechanism using magnetic force and a mechanism using concave and convex portions. However, the coupling mechanism is not limited to such a structure, and may be a screw that can be fastened from the surface of the decorative panel with the decorative panel attached.

In addition, when equipped with a coupling mechanism,
The connection mechanism may include an urging mechanism that urges the tank body side driving mechanism and the panel side driving mechanism in a connecting direction.
By doing so, it becomes possible to firmly connect the tank side drive mechanism and the panel side drive mechanism by the action of the urging mechanism. As the urging mechanism, for example, a urging mechanism using a spring or other elastic body can be used. Both the tank side drive mechanism and the panel side drive mechanism may be energized, or only one of them may be energized.

  When using a mechanism in which the concave and convex portions formed in the tank body side driving mechanism and the panel side driving mechanism are fitted as the coupling mechanism, the biasing mechanism is in a state where the positions of the concave and convex portions are inconsistent. However, the tank body side drive mechanism and the panel side drive mechanism may be displaceable so that the decorative panel can be assembled. When assembling the decorative panel, the positions of the concave and convex portions described above are not necessarily aligned. However, if the biasing mechanism can absorb the interference state due to the mismatch as described above, the decorative panel can be easily assembled. Can be assembled. Then, after assembling the decorative panel, by adjusting the position of the panel-side drive mechanism, if the concave portion and the convex portion are aligned, the urging force of the urging mechanism causes the tank-side drive mechanism and the panel-side drive mechanism to Can be easily connected.

In the present invention,
The decorative panel may be an apron attached to the tank body.
Apron is a decorative panel that is attached to the front of the tank. In general, there is no sufficient gap between the main body of the tank body and the apron, and it is very difficult to attach the drive mechanism of the drain plug device after the apron is attached. Accordingly, the apron is a site where the utility of the present invention is particularly high.
In addition, as a part where the operation part for operating the drain plug of the tank body is provided, the distance from the drain plug is short and the operation force can be transmitted efficiently, and the user operates while confirming the state of the drain plug. The front surface of the tank body is preferable because it is easy. From this point of view, the configuration in which the operation unit is provided in the apron is highly useful.

In the present invention,
The panel side drive mechanism may be a mechanism that transmits the operation force from the operation unit to the tank body side drive mechanism along the surface of the decorative panel.
By doing so, the position of the operation portion can be arbitrarily formed regardless of the position of the drain plug of the tank body. In addition, by preparing a wide variety of decorative panels with the position of the operation unit changed, the position of the operation unit can be easily changed by selecting and replacing the decorative panel while using the same tank body side drive mechanism. The convenience of the drain plug device can be improved.

In the present invention,
The said operation part is good also as what is attached in the state which does not protrude from the outer surface of the said decorative panel.
By carrying out like this, the external appearance of the decorative panel which attached the operation part can be improved. “Does not protrude” is not limited to a state in which the operation part is completely immersed inside the plane that forms the outer surface of the decorative panel, and does not impair the flat appearance of the decorative panel. What is necessary is just the state which does not protrude substantially to the extent.
In addition, the operation unit may be provided with a mechanism that does not protrude from the outer surface when not in use and pops up in a state protruding from the outer surface when in use. By doing so, it is possible to improve both the appearance and the operability.

In the present invention,
The said tank body side drive mechanism is good also as a thing provided with the cover which covers the outer side so that it may not leak.
By carrying out like this, the water leak from a tank side drive mechanism can be prevented, and the failure by this can be suppressed.
In addition, when the release wire as shown in FIG. 1 is used as the tank body side drive mechanism, when the replacement is performed, the above-mentioned cover serves as a guide, and the release wire is provided from one end to the other end of the tank body side drive mechanism. It becomes possible to pass.

  In the present invention, the various features described above are not necessarily all provided, and some of them may be omitted or combined as appropriate. The present invention can be configured as a manufacturing method for manufacturing the drain plug device in addition to the configuration as the drain plug device described above.

It is explanatory drawing which illustrates the drain plug apparatus as a prior art. It is explanatory drawing which shows schematic structure of the unit bus | bath in an Example. It is explanatory drawing which shows the structure of a drain plug device. It is explanatory drawing which shows the structure of the connection mechanism as a modification.

It is explanatory drawing which shows the structure of the apron as a modification.

A. Overall structure:
An embodiment of the present invention will be described taking a drain plug device attached to a bathtub of a unit bath as an example. In the embodiment, a case where a drain plug device is attached to a bathtub will be described as an example. However, the present invention is applicable not only to a bathtub but also to various tank bodies such as a wash basin.
FIG. 2 is an explanatory diagram illustrating a schematic structure of a unit bus in the embodiment.
The unit bath is provided with a bath tub 10 for bathing. The bathtub 10 is supported on the floor by a metal mount 1. A drain port 14 is formed on the bottom surface of the bathtub 10, and a drain plug device is attached thereto.
Several decorative panels are attached to the unit bath. In the figure, as an example of the decorative panel, a washing place panel 25 that is installed horizontally on the front side and serves as a washing place, and an apron 20 that covers the front face of the bathtub 10 vertically are shown. In addition, although illustration is abbreviate | omitted, the decorative panel which covers the indoor wall surface of a unit bath is also mounted | worn.

B. Structure of drain plug device:
FIG. 3 is an explanatory view showing the structure of the drain plug device.
FIG. 3A shows an outline of the entire structure in a cross-sectional view. The drain plug device is a device for opening and closing a drain plug 49 attached to a drain port formed on the bottom surface 11 of the bathtub 10. The drain plug device of the embodiment is driven by the tank body side drive mechanism 40 and the panel side drive mechanism 30. In order to avoid complication of the drawing, a portion for driving the drain plug 49 is schematically shown. For example, the mechanism shown in FIG. 1 can be applied.
The drain plug device of the embodiment is configured by connecting the tank body side drive mechanism 40 and the panel side drive mechanism 30, and the tank body side drive mechanism 40 is fixed to the back side of the flange 12 on the upper surface of the bathtub 10. Supported by a stay 15.
In the embodiment, the stay 15 fixed to the flange 12 is illustrated, but a stay 15A fixed to the gantry 1 may be used. In addition, when the apron 20 is assembled, the stay 15 can be provided in various parts as long as the tank side drive mechanism 40 can be supported. The stay 15 may be firmly attached, or may be supported to the extent that a large positional shift does not occur when the apron 20 is assembled even if the stay 15 is not so rigid that the position of the tank body drive mechanism 40 does not move. For example, the stay 15 can be attached to a heat insulating material inserted between the bathtub 10 and the apron 20, or the heat insulating material itself can be used as the stay 15.
In the tank body side drive mechanism 40, similarly to the mechanism shown in FIG. 1, the attachment portion 41 that receives the operation force from the panel side drive mechanism 30 and the drain plug 49 are connected by a release wire 48. Thus, an operating force for opening and closing the drain plug 49 can be transmitted.
Moreover, the outer periphery of the tank side drive mechanism 40 is covered with a guide tube 50 for preventing water leakage. By covering with the guide tube 50 in this way, leakage to the outside can be avoided, and when it becomes necessary to replace the release wire 48, the drain plug from the mounting portion 41 is inserted when the release wire 48 is inserted. Easy to guide up to 49.

  The front surface of the bathtub 10 is provided with a front surface portion 13 that is vertically lowered from the flange 12. An apron 20 is attached below the front surface portion 13. The apron 20 is formed with an opening 21 to which a panel drive mechanism 30 is attached.

FIG. 3B is an enlarged cross-sectional view of the connecting portion A between the tank body side drive mechanism 40 and the panel side drive mechanism 30.
The mounting portion 41 of the tank body side drive mechanism 40 is supported by a circular opening 16 formed in the stay 15. Inside the attachment portion 41, a cylindrical guide portion 41A is formed on the inner surface on the side where the guide tube 50 is attached, and the outer tube 48t of the release wire 48 is fixed to the root portion thereof.
On the other hand, a disc-shaped actuating portion 42 that moves in the left-right direction in the figure is attached to the attaching portion 41 by an operating force transmitted from the panel side drive mechanism 30. In order to prevent water leakage, it is preferable to install an O-ring, an X-ring, or the like between the mounting portion 41 and the operating portion 42.
An inner wire 48w of the release wire 48 is fixed at the center of the operating portion 42. Moreover, the cylindrical cylindrical part 43 provided in the center part is formed. The cylindrical portion 43 is fitted so as to slide on the outside of the guide portion 41A, and plays a role of suppressing buckling of the inner wire 48w. When the operation part 42 moves in the left-right direction, the operating force opens and closes the drain plug 49 via the inner wire 48w.
The panel side drive mechanism 30 is fixed to the opening 21 of the apron 20. Fixing can be performed in various ways. It is preferable to seal between the opening 21 and the panel side drive mechanism 30 so as not to leak water.

The panel side drive mechanism 30 incorporates an operation portion 32 for a user to operate inside a cylindrical attachment portion 31. In this embodiment, the operation unit 32 is a push button. The operation unit 32 is supported by a spring 33.
The operation unit 32 has a shape that does not protrude from the apron 20. By doing so, the appearance of the entire unit bus when the apron 20 is assembled can be improved.
A columnar or cylindrical protrusion 32A is formed on the back side of the operation unit 32. The end face of the protrusion 32 </ b> A is in contact with the operating portion 42 of the tank body side drive mechanism 40. Thus, when the operation unit 32 is operated, the operation force is transmitted to the operation unit 42 via the protrusion 32A.

  In the present embodiment, a configuration in which the protrusion 32A and the operating portion 42 are coupled by a magnetic force is applied. As illustrated, two magnets 44 </ b> A and 44 </ b> B are embedded in the operating portion 42. Two magnets 34A and 34B are also embedded in the protrusion 32A. The magnet 44A and the magnet 34A, and the magnet 44B and the magnet 34B are provided at opposing positions, and their polarities are set so that magnetic forces attracting each other act. By doing so, the attachment part 42 and the operation part 32 can be easily brought together by a magnetic force only by assembling the apron 20, and the operation force can be transmitted reliably and without waste. However, as long as only the pushing force is transmitted as in the embodiment, the protrusion 32A and the operating portion 42 do not necessarily have to be connected, so the above-described magnets 44A, 44B, 34A, 34B are omitted, It is good also as a structure which both touch only.

FIG. 3C is a perspective view of the connecting portion A between the tank side drive mechanism 40 and the panel side drive mechanism 30. As shown in the figure, the operating portion 42 is attached to the opening 16 of the stay 15, and the protrusion 32 </ b> A of the panel side drive mechanism 30 is attached to the opening 16. The protrusions 32 </ b> A and eventually the operation unit 32 are attracted to the operation unit 42 by the magnets 44 </ b> A and 44 </ b> B provided in the operation unit 42.
The polarities of the magnets 44A and 44B are preferably different from each other. For example, if the surface side of the magnet 44A is an N pole, the magnet 44B is an S pole. In response to this, the polarities of the magnets 34A and 34B attached to the protrusion 32A in the operation unit 32 are also set so as to attract the magnets 44A and 44B. By doing so, a repulsive force acts between the magnet 44A and the magnet 34B of the protrusion 32A, and only attracts the magnet 34A. Therefore, the operation unit 32 can be attached in a fixed direction. As shown in the figure, when characters such as “PUSH” are drawn on the operation unit 32, it is useful to be able to attach in such a fixed direction.

FIG. 3D is an enlarged cross-sectional view of a connecting portion A between the tank body side drive mechanism 40 and the panel side drive mechanism 30 as a modified example.
In the modified example, the mounting portion 41B of the tank body side drive mechanism 40 is formed with an overhanging portion 41D projecting to the outer peripheral side on the panel 20 side of the stay 15, and magnets 44C and 44D are embedded therein. . The internal structure of the mounting portion 41B and the guide portion 41C for sliding the cylindrical portion 43 of the operating portion 42 are the same as the embodiment shown in FIG.
On the other hand, the mounting portion 31B in the panel side drive mechanism 30 of the modified example is formed with an overhang portion 31D projecting to the outer peripheral side, and magnets 34C and 34D are embedded therein. The polarities of the magnets 44C and 44D and the magnets 34C and 34D are set so as to attract each other.
According to such a modification, the attachment portion 41B of the tank body side drive mechanism 40 and the attachment portion 31B of the panel side drive mechanism 30 can be attracted by magnetic force and connected to each other.

According to the drain plug device of the present embodiment, the operation unit 32 attached to the apron 20 and the operation unit 42 fixed by the stay 15 do not need to particularly perform the work for connecting the apron 20. It is easily connected just by assembling. This is because when the apron 20 is assembled, the stay 15 holds the actuating portion 42 by positioning the apron 20 at a position facing the protrusion 32A.
Therefore, according to the present embodiment, it is possible to easily realize a drain plug device in which the operation unit 32 is formed in a part other than the bathtub 10, that is, the apron 20.
Further, in the case of such a structure, if the apron 20 is removed, the tank-side drive mechanism 40 and the panel-side drive memory 30 can be easily separated, so that the drain plug device can be easily inspected and repaired. There is an advantage that can be.

C. Modification 1:
FIG. 4 is an explanatory view showing the structure of a coupling mechanism as a modified example.
In the embodiment (FIG. 3), an example of a mechanism for transmitting an operating force by a push button has been shown, but here, a mechanism for transmitting an operating force for rotating a knob is illustrated. The overall structure of the drain plug device is the same as in the embodiment (FIG. 2).
FIG. 4A is a perspective view of the coupling mechanism. In the modified example, an attachment portion 61 is fitted into the opening 16 of the stay 15, and an operation portion 62 that rotates inside is attached. A convex detent 61A is formed in the mounting portion 61, and the rotation of the mounting portion 61 can be prevented by fitting the detent 61A into the concave portion 16A formed in the opening 16 in the same shape. The inside of the operation part 62 is a recess, and protrusions 64A, 64B, and 64C are formed there.
On the other hand, the panel-side drive mechanism 70 fixed to the apron includes an operation unit 72 of a type that rotates the knob 72 </ b> A left and right inside a cylindrical attachment unit 71. The projection 73 at the tip of the operation unit 72 is formed with recesses 73A to 73C at positions facing the projections 64A, 64B and 64C (however, the recess 73B is shaded in the drawing). Absent). By fitting the recesses 73 </ b> A to 73 </ b> C of the operation unit 72 and the protrusions 64 </ b> A to 64 </ b> C of the operation unit 62, an operation force due to the rotation of the operation unit 72 can be transmitted to the operation unit 62.
In the illustrated example, the protrusions 64A to 64C and the recesses 73A to 73C are formed so as not to be point-symmetric. By doing so, the connection state between the operation unit 72 and the operation unit 62 is uniquely determined, and it is possible to avoid the operation unit 72 being attached in an incorrect direction. In order to make it easy to fit into the recesses 73A to 73C, it is preferable that the tips of the protrusions 64A to 64C have a tapered shape.

FIG. 4B is a cross-sectional view of the coupling mechanism. FIG. 4B shows a state in which the positions of the recesses 73A to 73C and the protrusions 64A to 64C of the operating portion 62 are mismatched.
As shown in the figure, the mounting portion 61 of the tank body side drive mechanism 60 is provided with an operating portion 62. A rotor 48r is connected to the operating part 62, and the operating force of rotation applied to the operating part 62 can be transmitted to the drain plug. By using the rotor 48r, the depth of the tank side drive mechanism 60 can be reduced. Such a mechanism is useful because the space between the tank and the apron is narrow. The operating part 62 is supported by a spring 65. The spring 65 urges the operating portion 62 toward the panel side drive mechanism (in the direction of arrow F in the figure). Thereby, the operation part 62 and the operation part 72 can be firmly connected.
Further, since the operating portion 62 is supported by the spring 65 and can move in the left-right direction in the figure, even when the positions of the recesses 73A to 73C and the protrusions 64A to 64C of the operating portion 62 are mismatched. The apron can be assembled so that the attachment portions 61 and 71 are in contact with each other. As shown in FIG. 4B, when the positions of the recesses 73A to 73C and the protrusions 64A to 64C are not aligned, the operating portion 62 is pushed by the protrusion 73 on the operation portion 72 side, so that the attachment portion It can be assembled in a state where 61 and the mounting portion 71 are in contact with each other. It is preferable that the operating part 62 has a movable range that can be assembled even if the positions of the recesses 73A to 73C and the protrusions 64A to 64C of the operating part 62 are mismatched.

FIG. 4C shows a state where the recesses 73A to 73C and the positions of the protrusions 64A to 64C of the operating portion 62 are aligned.
After assembling in an inconsistent state as shown in FIG. 4B, the positions of the recesses 73A to 73C and the protrusions 64A to 64C can be aligned by slightly rotating the operation portion 72. When the two are aligned, the operating portion 62 is urged by the spring 65, so it moves to the right side in the figure and is connected to the operating portion 72 in the original state where the recesses 73A to 73C and the projections 64A to 64C are engaged. Is done.
Thus, by supporting the operation part 62 with the spring 65, there exists an advantage which can implement | achieve a connection state more easily and reliably. Instead of the configuration shown in FIG. 4, the operation unit 72 may be supported by a spring, or both the operation unit 62 and the operation unit 72 may be supported by a spring.

In the first modification, the operation unit 72 may be supported by the pop-up mechanism 74. Such an example is shown.
FIG. 5 is an explanatory view showing the structure of the coupling mechanism provided with the pop-up mechanism 74. When the pop-up mechanism 74 is not operated, the operation portion 72 is stored so as not to protrude from the attachment portion 71, and when operated, the operation portion 72 is pushed out and released, thereby protruding from the attachment portion 71. It is a mechanism that can be made to. Since the internal structure of such a mechanism is well known, illustration is omitted. By providing such a pop-up mechanism 74, there is an advantage that the operability at the time of operation can be improved while the appearance when not operated is improved.
FIG. 5A shows a state before popping up. Similar to FIG. 4A described above, the positions of the recesses 731A to 731C and the protrusions 641A to 641C of the operating portion 621 are mismatched. Even when the operation unit 72 protrudes by the pop-up mechanism 74, these dimensions are longer than those in the case where there is no pop-up mechanism (example of FIG. 4) so that the recesses 731A to 731C and the protrusions 641A to 641C mesh with each other.
FIG. 5B shows a state where the concave portions 731A to 731C and the positions of the protrusions 641A to 641C of the operating portion 62 are aligned. This is the state before popping up. In the original state in which the recesses 731A to 731C and the protrusions 641A to 641C are engaged with each other, the two are connected.
FIG. 5C shows a pop-up state. As shown in the figure, the operation portion 72 protrudes from the surface of the attachment portion 71. In this example, since the lengths of the recesses 731A to 731C and the protrusions 641A to 641C are set to be longer than the movable range of the operation unit 72, they can be engaged with each other even in a pop-up state.

D. Modification 2:
FIG. 6 is an explanatory diagram showing the structure of an apron as a second modification.
FIG. 6A is a perspective view showing the overall structure. As in the embodiment, a drain plug device is attached to the bathtub 10. However, in the modification, the panel side drive mechanism 80 attached to the apron 20A is a mechanism capable of transmitting power along the surface of the apron 20A. That is, when the operation unit 81 is rotated, the panel side operation unit 82 can be rotated via the transmission mechanism 83.
FIG.6 (b) is explanatory drawing which shows the state of the drain plug device seen from the apron 20A side. The tank side drive mechanism 40 (incorporated in the guide tube 50) stands up substantially vertically, that is, in the vertical direction from the drain plug position of the bathtub, whereas the panel side drive mechanism 80 operates along the apron 20A. Since the force can be transmitted, the operation unit 81 can be provided in a portion shifted from the drain plug position in the longitudinal direction of the apron 20A. By raising the tank body side drive mechanism 40 substantially vertically in this way, the length of the tank body side drive mechanism 40 can be minimized, the structure can be simplified, and the driving force can be transmitted efficiently. There is an advantage that becomes possible.
Generally, in a tank body, the drain plug is often formed at the center of the bottom surface. Therefore, when the panel side drive mechanism is attached in accordance with the position of the drain plug, the operation unit is provided at the position of the panel side operation unit 82 in FIG.
On the other hand, if it is assumed that a mechanism capable of transmitting the operation force along the apron 20A is provided as in the modification 2, the operation unit 81 can be provided at an arbitrary position, and the appearance of the bathtub is improved. Convenience can also be improved.

FIG. 6C is an explanatory diagram showing an outline of a mechanism for transmitting the operating force. This mechanism is configured to transmit rotational torque using two sets of conduits 83B and 83C and inner members 83D and 83E. The conduits 83B and 83C are constituted by close coil springs. The inner members 83D and 83E inserted into the respective conduits 83B and 83C can be single wires or stranded wires. Although not shown, the conduits 83B and 83C are fixed to any part of the apron 20A. For protection, a cladding tube 83A covering the conduits 83B and 83C may be provided. In addition, for convenience of illustration, the conduits 83A and 83B are shown in a state of being arranged in parallel. However, since both are flexible members, the conduits 83A and 83B are in close contact and covered with the cladding tube 83A. There is no problem.
The inner materials 83D and 83E are fixed to the operation unit 81 and the panel side operation unit 82, respectively. The operation unit 81 and the panel side operation unit 82 are disk-like members that can rotate around the rotation shafts 81C and 82C, respectively. The operation portion 81 and the panel side operation portion 82 are constituted by pulleys, and the inner members 83D and 83E are formed as a series of annular wires, and the operation portion 81 and the panel side operation portion 82 are hooked on the operation portion 81 and the panel side operation portion 82. And so on.
In this structure, it is assumed that the operation unit 81 is rotated in the direction of the right rotation R1 as illustrated. By this rotation, a tensile force TR1 acts on the inner material 83B. This pulling force TR1 is transmitted by the inner member 83D and pulls the outer peripheral portion of the panel side operating portion 82 with the pulling force TR1, so that it can be rotated in the direction of the arrow R2. When the operation unit 81 is rotated in the reverse direction, similarly, the tensile force is transmitted by the inner material 83E, and the panel side operation unit 82 can be rotated.
The connection shown in FIG. 4 and FIG. 5 may be applied to the connection between the panel side operation unit 82 and the tank body side drive mechanism. By doing so, the operation force for rotating the operation unit 81 can be transmitted to the tank body side drive mechanism via the panel side operation unit 82.

  According to the structure of the modification 2, the operation part 81 can be formed in an arbitrary place in the apron 20A regardless of the position of the drain plug of the bathtub 10. In addition, by preparing various aprons 20A in which the position of the operation unit 81 is changed, the position of the operation unit 81 can be easily changed by selecting and replacing the apron 20A without changing the design of the tank side drive mechanism. There is also an advantage that can be changed.

In the above, the Example and modification of this invention were demonstrated. The various features shown in the embodiments and the modifications are not necessarily all provided, and some of them may be omitted or combined as appropriate.
In addition, the present invention can be configured in many variations. For example, in the embodiment and the modification, the mechanism for transmitting the pressing force and the rotational force is illustrated, but the operation unit may be a slider that slides.

  INDUSTRIAL APPLICABILITY The present invention can be used in a drainage device for a tank body because it can easily and reliably assemble a drainage device provided with an operation unit in addition to the body of the tank body.
