Description

  The present invention relates to a remote-operated drain plug device used to open and close a drain of a water tank such as a bathtub or a wash bowl.

  Conventionally, in a remote-operated drain plug device, when the operation part is attached to an attachment target part such as a rim surface of a bathtub, a flange member having a through hole for guiding the vertical movement of the operation part and a screw thread around the outer periphery of the flange member are provided. It was fixed so that the bathtub was clamped with the mating nut. In order to prevent water from entering the through hole from the flange member, a flat packing is provided between the flange of the flange member and the bathtub. However, since the flat packing is exposed around the flange, there is a problem that it does not look good.

JP 2008-248687 A

  Therefore, a structure in which this flat packing is sandwiched between a bathtub and a nut is considered. However, in this structure, it is necessary to arrange a sliding washer between the nut and the flat packing in order to secure the sliding property at the time of tightening, which is costly. Moreover, when it is set as the structure tightened by rotating a flange, the bottom face of the flange of a flange member will contact with the rim surface of a bathtub, and will be tightened while sliding. At this time, when a metal member such as stainless steel is caulked and coated to decorate the surface of the flange member, if the flange is turned with the end surface of the metal member hitting the rim surface of the bathtub, the rim surface of the bathtub There is a possibility of scratching. Further, when the end surface of the metal member hits the rim surface of the bathtub, there is a possibility that the tightening torque varies depending on how it hits, and the flat packing cannot be tightened with a desired torque.

  Then, an object of this invention is to attach the operation part of a remote-control type drain plug apparatus reliably, without damaging an attachment object part.

  In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that a drain plug lid for closing a drain port provided in a water tank is moved up and down via a release wire by operating an operation button so that the drain port is opened. In the operation part structure of the remote-operated drain plug device that opens and closes, it has a guide surface that is inserted from the surface side into a through-hole formed in the attachment target part to which the operation button is attached, and in which the operation button can be advanced and retracted A flange portion made of a resin having a cylindrical portion provided with a male screw around the periphery, and a flange formed so as to spread outward at an upper portion of the cylindrical portion and having a bottom surface abutting the attachment target portion, A tightening nut that is provided with a female screw that is screwed into a male screw of the cylindrical portion from the back surface side of the mounting target portion, and clamps the mounting target portion together with the flange; and the cylindrical portion of the flange member Of In the covering member surface of the metal of toward the flange from it an operation section structure of the remote controlled discharge valve device according to claim covering a to a position higher than the bottom surface of the flange.

According to this, since the flange of the operation part of the remote control type drain plug device is covered with the metal covering member, it is possible to make the appearance more luxurious than when the flange is painted or metal-plated. And the design is improved.
Moreover, since the edge part of the coating | coated member in the outer peripheral side of a flange covers even a position higher than the bottom face of a flange so that it may not reach the bottom face of a flange, a metal coating | coated member does not contact an attachment object part. Therefore, when the flange member is tightened to the tightening nut, the attachment target portion is not damaged at the end portion of the covering member even if the flange member is turned.

  The invention according to claim 2 is characterized in that a concave portion larger than the thickness of the covering member is formed in the lower peripheral portion of the flange, and an end portion of the covering member is accommodated in the concave portion. It is an operation part structure of the remote-control type drain plug device.

  According to this, since the edge part of the coating | coated member in the outer peripheral side of a flange is stored in the recessed part of the outer periphery strain | stump | stock of a flange, it becomes possible to space apart the edge part of a coating | coated member from an attachment object part reliably.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to attach reliably the operation part of a remote-control type drain plug apparatus, without damaging an attachment object part.

FIG. 1 is a schematic view showing a drain plug device according to an embodiment of the present invention.
The drain plug device 100 includes a drain plug portion 100A attached to a drain port 210 provided in the bathtub 200 (water tank) and an operation portion attached to a through hole 221 (see FIG. 3) formed in the rim surface 220 of the bathtub 200. 100B, and is a remote-operated drain plug device in which a drain plug portion 100A and an operation portion 100B are connected by a release wire 160. The release wire 160 is disposed inside a hose 170 provided so as to connect the operation unit 100B and the drain plug unit 100A, and is configured such that the inner wire advances and retreats inside the outer tube.

  The drain plug portion 100A has a support fitting 180 attached to the lower portion of the drain port 210 of the bathtub 200 to hold the operating portion 165 provided at one end of the release wire 160, and the drain portion 210 that closes the drain port 210 at the operating portion 165. A lid 190 is attached. The operation part 165 raises and lowers the drain plug lid 190 via the release wire 160 by operating an operation button 150 described later, thereby opening and closing the drain port 210. Although not shown, one end of the hose 170 described above is attached to the support fitting 180.

Next, the operation unit 100B will be described.
2 is a side view showing an operation part of the drain plug device, FIG. 3 is a central longitudinal sectional view of the operation part, FIG. 4 is a partially enlarged sectional view of the operation part, and FIG. 5 is an exploded view of the operation part.
The operation unit 100B includes a flange member 110 provided with an outward flange 112 at an upper end portion of a cylindrical portion 111 having a male screw 113 formed on the outer peripheral surface, and a female screw 121 that is screwed to the male screw 113 of the flange member 110. A fastening nut 120 having a connection portion 130 that holds a mechanism portion 162 provided at the other end of the release wire 160 and is connected to the lower end of the cylindrical portion 111 of the flange member 110 from below; A connecting pipe connector 140 to be attached to the nut 120 and an operation button 150 disposed in the cylindrical portion 111 of the flange member 110 so as to be able to advance and retract are provided. 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. The flange member 110 and the operation button 150 are each made up by covering a thin metal member on the surface of the resin member in order to give a high-class feeling.

  As described above, the flange member 110 includes the flange 112 formed so as to spread outward at the upper end portion of the cylindrical portion 111 in which the external thread 113 is formed on the outer peripheral surface. The bottom surface of the flange 112 is in contact with the rim surface 220 of the bathtub 200. The surface from the upper part on the inner peripheral side of the cylindrical portion 111 of the flange member 110 to the flange 112 is covered with a metal covering member 115. The covering member 115 is obtained by processing a metal such as glossy stainless steel into a thin plate shape, and is integrated with the flange member 110 by caulking. The end portion on the outer peripheral side of the covering member 115 covers up to a position slightly higher than the bottom surface of the flange 112. That is, the end portion of the covering member 115 is not in contact with the rim surface 220 of the bathtub 200. More specifically, a concave portion 116 in which the end portion of the covering member 115 is received is formed in the lower outer periphery of the flange 112. The minimum value of the dimension between the lower surface of the flange 112 and the rim surface 220 of the bathtub 200 in the recess 116 is set larger than the thickness of the covering member 115. Thereby, the covering member 115 crimped to the flange 112 does not contact the rim surface 220 of the bathtub 200.

  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. 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.

  Here, the screwing of the flange member 110 and the tightening nut 120 is performed by rotating the flange member 110 with another tool in a state where the tightening nut 120 is temporarily fixed by being pressed by a tool or a hand. Therefore, the flange member 110 turns on the rim surface 220 of the bathtub 200. However, since the covering member 115 covers the flange 112 of the flange member 110 up to a position slightly higher than the bottom surface of the flange 112, the covering member 115 does not reach the bottom surface of the flange 112. Therefore, even if the flange member 110 is rotated on the rim surface 220, the covering member 115 does not contact the rim surface 220, so that the rim surface 220 is not greatly damaged at the end of the covering member 115.

  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.

  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.

Next, a structure for connecting the connecting pipe 140 to the operation section guide section A will be described.
6 is a side view showing a state in which the operation part is attached to the rim part of the bathtub, FIG. 7 is a central longitudinal sectional view showing the operation part in the same state as FIG. 6, and FIG. 8 is a tightening to attach the flange member to the rim part of the bathtub It is a side view which shows a nut.

  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.

Next, a modified example of the above-described embodiment will be described.
FIG. 9 is a side view showing a modified example of the tightening nut.
In this modification, the inclined guide portion 122b of the guide groove 122 is eliminated from the embodiment of FIG. 8, and a vertical guide portion 122d is provided instead.
In this example, when connecting the connection pipe 130, the connection pipe connection tool 140 is turned to match the position of the protrusion 141 of the connection pipe connection tool 140 with the guide groove 122, so that the connection pipe connection tool 140 is moved to the vertical guide portion. After pushing upward along 122d, the connecting pipe connector 140 is rotated again to cause the protrusion 141 to reach the lock position 122c.
According to this, the connecting pipe 130 is not gradually inserted into the concave portion 123 of the tightening nut 120, but has the same effect as the above-described embodiment.

  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. In the present embodiment, the guide groove 122 is provided on the operation section guide section A side, and the projection 141 is provided on the connecting pipe connector 140. Instead, the projection 141 is provided on the operation section guide section A. The guide groove 122 may be provided in the connecting pipe connector 140. Further, the connecting pipe connector 140 can be connected to the cylindrical portion 111 of the flange member 110 of the operation portion guide portion A instead of connecting to the tightening nut 120 of the operation portion guide portion A. is there. Further, the latch mechanism may be built in the operating unit 165 instead of being built in the mechanism unit 162.
