At that time, as shown in Patent Document 2, vertical ribs may be formed on the outer peripheral portion of the operation button so that the operation button slides smoothly.

JP 2004-150065 A JP 2012-36708 A

As described above, in order to enhance the design of the operation unit that can smoothly slide the operation button, the upper surface of the operation button is caulked with a metal plate to make a metallic luster. ing.
However, the metal plate that is crimped on the upper surface of the operation button goes around to the side surface of the operation button due to the characteristics of crimping. Then, when the operation button slides inside the casing portion, the metal plate rubs against the casing portion, the operation button cannot be smoothly slid, and the metal plate is scratched and glossy. May be lost.
Therefore, in order to solve such problems, the present invention provides a remote-controlled drain plug operation unit structure in which the metal plate that is caulked on the upper surface of the operation button does not rub against the surroundings by sliding the operation button. The purpose is to obtain.

In a remotely operated drainage plug that opens and closes the drainage port by opening and closing the drainage port lid that closes the drainage port provided in the water tank through a release wire by operating the operation button, the attachment target part to which the operation button is attached A flange member having a guide surface that is inserted into the formed through-hole from the surface side and capable of moving the operation button forward and backward, and a mechanism unit that transmits an advance / retreat operation of the operation button to the release wire. The button is a decorative part made by caulking the upper surface of the resin molded product with a metal plate, and on the side surface of the operation button, a rib protruding toward the side surface of the flange member is formed as a sliding guide part , The protruding amount of the rib toward the side surface of the flange member is the same as or larger than the outer diameter of the decorative part .

  According to this, the outer edge of the rib formed on the side surface of the operation button slides on the guide surface of the flange member. And since the rib protrudes toward the side surface of a flange member, it can suppress that the metal plate of a decoration part rubs the guide surface of a flange member. Therefore, the operation button can be operated smoothly, and further, the metal plate can be prevented from being damaged and the gloss of the metal plate can be maintained for a long time.

  The invention of claim 2 is characterized in that the protruding amount of the rib toward the side surface of the flange member is larger than the outer diameter of the decorative portion.

  According to this, it can prevent reliably that the metal plate of a decoration part rubs a flange member.

  According to a third aspect of the present invention, a plurality of the ribs are formed so as to run in the vertical direction, and a protrusion interposed between the ribs formed on the operation button is formed on the guide surface of the flange member. Features.

  The operation buttons can be pressed from an angle. By pushing the operation button from an oblique direction, a force is applied to rotate the operation button, and the operation button tries to rotate inside the flange member. If the operation button turns, you can slide it with your finger, and the force to press the operation button will be lost, and you may not be able to operate it properly. However, according to the present invention, even if the operation button is pushed obliquely, the operation button does not turn because the rib and the protrusion interfere with each other. Therefore, the force for pressing the operation button is not lost, and the pressing operation is easy to perform.

  The invention according to claim 4 is characterized in that the resin molded product of the operation button is constituted by a cored bar portion that is crimped by the metal plate and an exposed part that is insert-molded in the cored bar portion.

  In order to crimp the metal plate, a space for bending the metal plate is required. Since the operation button of the present invention has ribs formed on the side surfaces, the space is not sufficient and it is difficult to caulk the metal plate. However, according to the present invention, the resin plate may be insert-molded after the metal plate is crimped on the metal core, and therefore, the operation button can be easily produced by crimping the upper surface of the operation button with ribs with metal. .

  The invention of claim 5 is characterized in that an end portion of the metal plate is embedded in an exposed portion of the resin molded product.

  According to this, since the end portion of the crimped metal plate is concealed with resin, the unevenness of the end portion of the metal plate caused by crimping the metal plate is not exposed, so the appearance of the operation button is even better. It will be a thing.

  According to the present invention, it is possible to obtain an operation portion structure of a remote-operated drain plug in which a metal plate that is caulked on the upper surface portion of the operation button does not rub against the surroundings by sliding of the operation button.

The flange member 110, the tightening nut 120, the connection pipe 130, the connection pipe connector 140, and the operation button 150 are all resin members. Among these, the flange member 110 and the operation button 150 are decorated so that the upper surface of the resin molded product is squeezed with the metal plates 116 and 152 so that the metallic luster appears.

  The flange member 110 is inserted into the through hole 221 from the surface side of the rim surface 220 of the bathtub 200. The tightening nut 120 screws the female screw 121 into the male screw 113 of the flange member 110 from the back side of the rim surface 220 of the bathtub 200. The female screw 121 is fastened to the male screw 113, and the rim surface 220 of the bathtub 200 is held between the flange 112 of the flange member 110 and the fastening nut 120. And the inner periphery of the cylindrical part 111 of the flange member 110 becomes the guide surface 114 which supports the operation button 150 so that advancement / retraction is possible. In addition, a protrusion 115 protruding toward the inner peripheral side is formed at the lower end of the guide surface 114. Accordingly, the flange member 110 and the tightening nut 120 serve as an operation portion guide portion A that guides the advancement and retreat of the operation button 150 with respect to the through hole 221 provided in the rim surface 220 of the bathtub 200.

  The tightening nut 120 is provided with a plurality of guide grooves 122 to be described later below the outer peripheral surface thereof. Further, a recess 123 into which the upper end portion of the connection pipe 130 can be inserted is formed in the lower portion of the tightening nut 120.

  The connecting pipe 130 has a lower end connected to a hose 170 surrounding the release wire 160, and an upper end connected to the operation unit guide A. In addition, a holding portion 131 that holds the mechanism portion 162 is formed inside the connecting pipe 130. Further, the connecting pipe 130 has a protruding portion 132 with an upper end protruding outward, and a groove 134 for fitting the O-ring 133 is provided on the outer peripheral side surface thereof. When the connecting pipe 130 is connected to the operation portion guide part A, the O-ring 133 is inserted into the recess 123 of the tightening nut 120 when the connecting pipe 130 is connected to the inner periphery of the recess 123 of the tightening nut 120. Seal closely to the surface.

  The connection pipe connector 140 is rotatably provided at the end near the upper part of the connection pipe 130. Specifically, the connection tube connector 140 is partially engaged with the shallow groove portion 135 formed around the upper portion of the connection tube 130 so that the connection tube connection device 140 can be rotated along the shallow groove portion 135. Yes. In addition, the horizontal upper surface of the connecting pipe connector 140 is in contact with the lower surface of the protruding portion 132 of the connecting pipe 130 in a state where the connecting pipe connector 140 is engaged with the shallow groove portion 135. A plurality of protrusions 141 to be described later are provided above the inner periphery of the connection pipe connector 140.

  When connecting the connecting pipe 130 to the operating section guide section A, the operating section connecting tool 140 is turned in a state where the upper end of the connecting pipe 130 is close to the operating section guide section A, and the protrusion 141 is connected to the above-described tightening nut 120. Then, the operation part connector 140 is further rotated to reach the projection 141 to the lock position 122c of the guide groove 122, and the connection of the connection pipe 130 is completed.

  The operation button 150 is attached to the tip of a rod 163 that protrudes from the inside of the mechanism portion 162 toward the operation button. Each time the operation button 150 is pressed, a force for pressing the operation button 150 is transmitted from the rod 163 to the mechanism portion 162, and the drain plug lid 190 is moved up and down via the release wire 160.

As described above, the operation button 150 includes the decorative portion 150a in which the upper surface of the resin molded product 151 is crimped with the metal plate 152 and the rib 153 protruding toward the side surface of the flange member on the side surface of the resin molded product 151. And a formed sliding guide portion 150b. The end of the metal plate 152 is embedded in the resin molded product 151. A plurality of ribs 153 are formed along the vertical direction of the operation button 150. The plurality of ribs 153 are formed at intervals such that the protrusions 135 of the flange member 110 are interposed between the adjacent ribs 153. In the present embodiment, the protruding amount of the rib 153 is substantially the same as the outer diameter of the decorative portion 150a.
The operation button 150 is slidable in the vertical direction so that the outer edge of the rib 153 is along the guide surface 114 of the flange member 110.

  Whenever the operation unit 150 is pressed, the mechanism unit 162 pushes the rod 163 into the mechanism unit 162 and presses the inner wire of the release wire 160 in the mechanism unit 162, thereby moving the operation button 150 forward and backward to the release wire 160. It functions to communicate. Further, when the user releases the operation button 150, a return spring (not shown) that raises the pushed rod 163 is built in and functions to raise the operation button 150. Further, in this embodiment, a latch mechanism (not shown) is built in the mechanism unit 162 so that the push button 150 is alternately positioned at a high position and a low position each time the push button 150 is pressed. The drain plug lid 190 is held at a position where the drain port 210 is closed and a position where the drain port 210 is opened.

  In the operation button 150, the outer edge of the rib 153 formed on the side surface of the resin molded product 151 slides up and down along the guide surface 114 of the flange member 110. The rib 153 protrudes toward the side surface of the flange member 110. The protruding amount is the same as or larger than the outer diameter of the decorative portion 150a obtained by crimping the metal plate 152. Therefore, it is possible to suppress the metal plate 152 of the decorative portion 150a of the operation button 150 from rubbing the guide surface 114 of the flange member 110. Therefore, the operation button 150 can be operated smoothly. Furthermore, the metal plate 152 can be prevented from being damaged, and the gloss of the metal plate 152 can be maintained over a long period of time.

In addition, a plurality of ribs 153 are formed so as to run in the vertical direction, and a protrusion 115 interposed between the ribs 153 formed on the operation button 150 and the ribs 153 is formed on the guide surface 114 of the flange member 110. .
When the operation button 150 is pushed from an oblique direction, a force to rotate the operation button 150 is applied, and the operation button 150 tries to rotate inside the flange member 110. When the operation button 150 is rotated, the finger may slip and the force to press the operation button 150 may be lost, and the operation may not be performed well. However, according to the operation unit structure of the present embodiment, even if the operation button 150 is pushed obliquely, the operation button 150 does not rotate because the rib 153 and the projection 115 interfere with each other. Therefore, the force for pressing the operation button 150 is not lost, and the pressing operation is easy to perform.

Next, a structure for connecting the connecting pipe 140 to the operation section guide section A will be described.
FIG. 5 is a side view showing a state in which the operation unit is attached to the rim portion of the bathtub, and FIG. 6 is a central longitudinal sectional view showing the operation unit in the same state as FIG.

  As described above, the connection pipe connector 140 is provided with the protrusion 141 above the inner periphery thereof. In the present embodiment, four protrusions 141 are provided at intervals of 90 degrees.

  Further, the tightening nut 120 that constitutes a part of the operation portion guide portion A is provided with four guide grooves 122 into which the protrusions 141 can be inserted on the outer periphery thereof, like the protrusions 141. The guide groove 122 is formed by recessing the outer peripheral surface of the tightening nut 120 inward. The recess of the guide groove 120 has an appropriate depth so that the protrusion 141 does not come out of the guide groove 120 and does not idle. Further, the front of the guide groove 122 is opened to the lower surface of the tightening nut 120, and the protrusion 141 is inserted from the open end.

A lock portion that restrains the inserted protrusion 141 so as not to move is provided at the back of the guide groove 122. In the present embodiment, the lock portion is constituted by a step portion 122a that partially shallows the bottom surface 122e of the guide groove 122. When locking the connecting pipe connector 140, the connecting pipe connector 140 is rotated so that the apex of the protrusion 141 is moved over the stepped portion 122 a by rotating the connecting pipe connector 140. The lock position 122c is reached.
Further, an inclined guide portion 122b for guiding the protrusion 141 received in the guide groove 122 obliquely upward is provided between the open end of the guide groove 122 and the stepped portion 122a.
Further, a drop prevention portion 124 is provided in the guide groove 122. In the present embodiment, the drop-off prevention portion 124 is provided with a protruding wall that protrudes outward from the step portion 122 a, that is, below the lock position 122 c of the guide groove 122, so that the protrusion 141 is removed from the guide groove 122. It is configured not to come off. As a result, even when a force is applied in a direction in which the connecting pipe 130 is tilted to the left and right, the protruding wall works to increase the amount of protrusion of the protrusion 141 on the guide groove 122. It can prevent coming off from the guide part A.

  When connecting the connection pipe 130 to the operation section guide section A, first, the operation section connecting tool 140 is turned with the upper end of the connection pipe 130 being close to the operation section guide section A, and the protrusion 141 is tightened as described above. Insert into the guide groove 122 of the nut 120. Subsequently, the operation unit connector 140 is continuously rotated, and the projection 141 is moved in the inclined guide portion 122b of the guide groove 122 to move the connection tube connector 140 upward, and the upper end of the connection tube 130 is tightened with the tightening nut. It is made to insert gradually in the recessed part 123 provided in the lower surface of 120. At this time, the O-ring 133 attached to the connection pipe 130 is also inserted into the recess 123 with a light force by turning the connection pipe connector 140. Then, the operation unit connector 140 is further rotated so that the protrusion 141 reaches the lock position 122c of the guide groove 122, and the connection of the connection pipe 130 is completed.

  Thus, in the present embodiment, the connection pipe 130 can be connected to the operation section guide portion A by slightly turning the connection pipe connector 140 attached to the connection pipe 130 in a rotatable manner. Therefore, the connection pipe does not become poorly connected due to a mounting error of the detachable lock member as in the conventional case. In addition, since the connecting pipe connector 140 is not a cap nut with a large amount to be tightened, it can be connected by turning the connecting pipe connector 140 a little. Hard to happen. That is, since the connection pipe 130 can be reliably attached to the operation section guide part A by a simple operation, problems due to poor attachment of the connection pipe 130 can be eliminated.

  Further, since the positioning step 122a that restrains the protrusion 141 at the lock position 122c is formed in the back of the guide groove 122, it is possible to prevent the connecting pipe connector 140 from coming off naturally.

  Further, in a state where the projection 141 reaches the lock position 122c and the connection pipe 130 is connected to the operation section guide part A, for example, a force in a direction in which the connection pipe 130 is tilted left and right by pulling the hose 170 obliquely or the like. Even if this works, the drop-off prevention part 124 prevents the protrusion 141 from coming off the guide groove 122, so that the connecting pipe 130 can be connected more firmly.

  Further, by providing the guide nut 122 in the tightening nut 120, it is possible to reduce the area occupied when the operation portion guide portion A is previously attached to the rim surface 220 of the bathtub 200. Therefore, a large work space below the rim surface 220 of the bathtub 200 can be secured, and for example, workability of construction of a wall panel that covers the back side of the bathtub 200 can be improved.

  Further, the guide groove 122 has an inclined guide portion 122b that allows the connecting tube 130 to be gradually inserted into the operation portion guide portion A. The guide tube 122 is guided to the operation portion guide portion A while the protrusion 141 is guided by the inclined guide portion 122b. By gradually inserting, the O-ring 133 provided in the connection pipe 130 is disposed between the operation portion guide part A and the connection pipe 130. Accordingly, the O-ring 133 is interposed between the operating portion guide portion A and the connecting tube 130 by utilizing the movement of rotating the connecting tube connector 140 and gradually inserting the connecting tube connector 140 into the operating portion guide portion A. Therefore, the O-ring 133 can be easily pushed between the operation portion guide portion A and the connection pipe 130.

Subsequently, a second embodiment of the present invention will be described.
FIG. 7 is a schematic longitudinal sectional view of the operation unit of the drain plug device according to the second embodiment, and FIG. 8 is a schematic cross section of the operation unit in a state where the operation button of the drain plug device according to the second embodiment is pressed. 9 is a cross-sectional view taken along the line XX in FIG. 7, FIG. 10 is a side view of the operation button in the second embodiment, and FIG. 11 is a central longitudinal cross-sectional view of the operation button in the second embodiment. .
In addition, about the structure which is common in 1st embodiment mentioned above, the same code | symbol is attached | subjected to drawing and the description is abbreviate | omitted.

The operation part of the drain plug device in the second embodiment is different from the first embodiment in the structure of the operation button 150.
First, the operation button 150 increases the protruding amount of the rib 153 so that the outer edge of the rib 153 reaches the outer side of the decorative part crimped with the metal plate. Thereby, it is possible to more reliably prevent the side surface of the crimped metal plate 152 from rubbing against the guide surface 114 of the flange member 110.

  The operation button 150 divides the resin molded product 151 into a cored bar portion 151a and an exposed portion 151b. The cored bar 151a is a part formed in a thin disk shape with a hole in the center. The metal core part 151a and the metal plate 152 are integrated by placing a metal plate 152 wider than the metal core part 151a on the upper surface of the metal core part 151a and caulking the periphery of the metal plate 152. In this state, the operation button 150 is obtained by insert molding resin into the cored bar 151a. Since the resin constituting the metal core portion 151a and the resin to be insert-molded are homogeneous resins, they are integrated without being separated after molding. The plurality of ribs 153 of the operation button 150 become an obstacle when the upper surface of the operation button 150 is caulked with the metal plate 152, and it is difficult to caulk the metal plate 152 after the resin molded product 151 is completed. However, as described above, the resin molded product 151 is divided into the core metal portion 151a and the exposed portion 151b, and after the metal plate 152 is crimped to the core metal portion 151a, the exposed portion 151b is insert-molded. Although the ribs 153 are provided on the metal plate 152, the metal plate 152 can be easily decorated by caulking.

  Further, by this insert molding, the end of the crimped metal plate 152 is covered with resin, and the end of the metal plate 152 is embedded in the resin. Concavities and convexities are formed at the end of the crimped metal plate 152, but the concavities and convexities of the metal plate 152 are not exposed on the surface of the operation button 150 because the end is embedded with resin. Thereby, the appearance of the operation button 150 is further improved.

  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention.

  Although this embodiment demonstrated the example which attaches the drain plug apparatus 100 to the bathtub 200, this invention is applicable also when attaching to a wash bowl. Moreover, although the bathtub 200 was illustrated and explained as the attachment target portion of the operation button 150, the upper surface of the counter adjacent to the bathtub 200 may be the attachment target portion of the operation button 150. Moreover, the attachment target part to which the operation button 150 is attached is not limited to a horizontal plane, and may be a vertical plane or an inclined plane. Further, the latch mechanism may be built in the operating unit 165 instead of being built in the mechanism unit 162.
