By mounting the pedestal portion 44 on the mounting portion 220, the pedestal portion 44 restricts the downward movement of the attachment member 26 in the pipe 200. Further, the pedestal portion 44 is pressed downward by the drainage port member 22, thereby restricting the upward movement. In other words, the pedestal portion 44 is sandwiched between the mounting portion 220 and the drain port member 22 in the pipe 200.

The pedestal portion 44 has a regulation portion 45. The pedestal portion 44 regulates the rotation of the attachment member 26 in the pipe 200 in the horizontal direction by bringing the regulating portion 45 into contact with the inner surface of the second pipe portion 212 of the pipe 200 from the side (see FIG. 2).

In this way, the attachment member 26 is mounted on the mounting portion 220 in the pedestal portion 44. The first storage space 221 of the pipe 200 stores the pedestal portion 44 of the attachment member 26. The attachment member 26 is mounted in the pipe 200 via the pedestal portion 44, so that the operating portion 24 and the holding portion 40 are arranged at predetermined positions in the pipe 200.

The holding portion 40 has a first main body portion 51 and a first opening portion 51a. The first main body 51 has a tubular shape. The first opening 51a is provided on the side of the first main body 51, and the operating portion 24 can be inserted horizontally into the first main body 51 from the side. The inner diameter of the first main body 51 is set to be substantially the same as or slightly smaller than the outer diameter of the operating portion 24. As a result, the operating portion 24 inserted into the first main body 51 fits into the first main body 51. The holding portion 40 holds the operating portion 24 by, for example, fitting the operating portion 24 and the first main body portion 51.

The pedestal portion 44 has a second main body portion 52 and a second opening portion 52a. The second main body 52 has a tubular shape. The second opening 52a is provided on the side of the second main body 52, and the operating portion 24 can be inserted horizontally into the second main body 52 from the side.

At least a part of the second opening 52a faces in the same direction as at least a part of the first opening 51a in the horizontal direction. In this example, the entire first opening 51a faces the same direction as a part of the second opening 52a. When viewed from the side, the entire first opening 51a is exposed through the second opening 52a. The minimum lateral width W2 (opening width) of the second opening 52a is larger than the minimum lateral width W1 of the first opening 51a, and the second main body 52 does not overlap with the first opening 51a in the horizontal direction. As a result, it is possible to prevent the second main body 52 from becoming an obstacle when the operating portion 24 is inserted and removed from the first main body 51. The operating portion 24 can be easily inserted and removed from the first main body portion 51. For example, a part of the second main body 52 may overlap with a part of the first opening 51a in the horizontal direction as long as it does not significantly hinder the insertion and removal of the operating part 24. The first opening 51a may have a portion that faces in a direction different from that of the second opening 52a.

The minimum lateral width W2 of the second opening 52a is larger than the maximum lateral width Ws of the operating portion 24. On the other hand, the minimum lateral width W1 of the first opening 51a is smaller than the maximum lateral width Ws of the operating portion 24. For the attachment member 26, for example, a resin material such as polypropylene is used. The attachment member 26 has elasticity. As a result, the holding portion 40 can temporarily deform the first main body portion 51 so as to widen the first opening portion 51a.

At the lower end of the first main body 51, a pair of ribs 51r arranged so as to face each other with the opening 51a interposed therebetween are provided. Each rib 51r projects inward of the first main body 51. A groove 24c is provided in the case 24a of the operating portion 24. The groove 24c is provided near the lower end of the case 24a, and is formed in a concave shape recessed inward from the side surface of the case 24a. The shape of the groove 24c corresponds to the shape of each rib 51r.

When the operating portion 24 is held by the holding portion 40, the operating portion 24 is inserted into the second opening 52a from the side and then pressed horizontally against the first opening 51a to be pressed horizontally against the first opening 51a. By elastically deforming the first opening 51a, the first opening 51a is expanded. Then, the operating portion 24 is inserted from the side into the first main body portion 51 from the widened first opening 51a. At this time, each rib 51r is fitted into the groove 24c. As a result, the operating portion 24 is inserted into the first main body portion 51, and the vertical movement of the operating portion 24 is restricted by the engagement between each rib 51r and the groove 24c. In other words, the engagement of each rib 51r with the groove 24c suppresses the actuating portion 24 from coming off from both ends in the axial direction of the first main body portion 51. As a result, the operating portion 24 is held by the holding portion 40.

The connecting portion 42a, which is one of the plurality of connecting portions 42, extends from one side end portion 51b of the first main body portion 51 toward the pedestal portion 44. The connecting portion 42b, which is another one of the plurality of connecting portions 42, extends from the other side end portion 51c of the first main body portion 51 toward the pedestal portion 44.

Further, the connecting portion 42a extends toward one side end portion 52b of the second main body portion 52. The connecting portion 42b extends toward the other side end portion 52c of the second main body portion 52. That is, the connecting portion 42a extends from the side end portion 51b of the first main body portion 51 toward the side end portion 52b of the second main body portion 52. The connecting portion 42b extends from the side end portion 51c of the first main body portion 51 toward the side end portion 52c of the second main body portion 52.

One side end 52b of the second main body 52 projects from the connecting portion 42a toward the second opening 52a. On the other hand, the other side end portion 52c of the second main body portion 52 is substantially flush with the side surface of the connecting portion 42b. In other words, the side end portion 52c does not protrude toward the second opening 52a with respect to the connecting portion 42b.

Contrary to the above, the side end portion 52b may be substantially flush with the side surface of the connecting portion 42a, and the side end portion 52c may be projected from the connecting portion 42b toward the second opening 52a. Alternatively, both the side end portions 52b and 52c may be projected from the connecting portion 42 toward the second opening 52a. That is, at least one of the side end portion 52b and the side end portion 52c may protrude from the connecting portion 42 toward the second opening 52a.

The amount of protrusion of the side end portions 52b and 52c is, for example, 10 mm or less. The state in which the connecting portion 42a extends toward the side end portion 52b is, for example, a state in which the distance between the side end portion 52b and the connecting portion 42a is 10 mm or less. The state in which the connecting portion 42b extends toward the side end portion 52c is, for example, a state in which the distance between the side end portion 52c and the connecting portion 42b is 10 mm or less.

Further, the connecting portion 42c extends from the side of the first main body portion 51 opposite to the first opening 51a to the pedestal portion 44 toward the side opposite to the first opening 51a.

When attaching the drain plug portion 12 of the drain plug device 10 to the bathtub 100 and the pipe 200, first, the pipe 200 is installed at a predetermined position in the bathroom. The operating portion 24 is connected to one end of the release wire 16 in advance. Then, one end of the operating portion 24 and the release wire 16 is inserted into the pipe 200 through the through hole 202. After inserting the operating portion 24, the support shaft 24b is exposed from the opening end 211a.

After the operating portion 24 is pushed out above the pipe 200, the operating portion 24 is inserted from the side into the second main body 52 from the second opening 52a, and the operating portion 24 is inserted into the first main body 51 from the first opening 51a. By inserting the operating portion 24 from the side, the operating portion 24 is held by the holding portion 40 of the attachment member 26.

After that, the pedestal portion 44 of the attachment member 26 is inserted into the pipe 200. The pedestal portion 44 is inserted into the pipe 200 until it is mounted on the mounting portion 220. In other words, the pedestal portion 44 is inserted into the pipe 200 until it comes into contact with the mounting portion 220. Then, the pedestal portion 44 is installed in the pipe 200 by inserting the regulation portion 45 into the second pipe portion 212 of the pipe 200. As a result, the operating portion 24 is installed in the pipe 200.

After installing the operating portion 24 in the pipe 200, the bathtub 100 is installed on the pipe 200 by aligning the positions of the opening end 211a and the drain port portion 102. In this case, the operating portion 24 is exposed upward through the drain port 102a.

After installing the bathtub 100, the drainage port member 22 is inserted into the drainage port 102a and the pipe 200 from above. Then, the male threaded portion 22c of the drainage port member 22 is screwed into the female threaded portion 214 of the pipe 200, and the bathtub 100 is sandwiched between the flange portion 22b and the pipe 200, whereby the bathtub 100 and the pipe are piped through the drainage port member 22. Connect with 200. Further, by sandwiching the pedestal portion 44 between the drain port member 22 and the mounting portion 220, the pedestal portion 44 is prevented from moving upward.

After that, the stopper lid 20 is attached to the upper end of the support shaft 24b of the operating portion 24. With the above, the installation of the drain plug portion 12 of the drain plug device 10 is completed. The operation unit 14 may be attached to the rim surface 104 of the bathtub 100 in advance before the attachment of the drain plug portion 12, or the rim surface 104 of the bathtub 100 after the attachment of the drain plug portion 12. It may be attached to.

As described above, according to the drain plug device 10 according to the present embodiment, since the holding portion 40, the connecting portion 42, and the pedestal portion 44 of the attachment member 26 are integrated, the holding portion 40 and the pedestal portion are integrated. The configuration can be simplified as compared with the case where the 44 is configured separately. As a result, the assembly work can be simplified, the number of parts can be reduced, and the manufacturing cost can be suppressed. Further, since at least a part of the second opening 52a faces the same direction as at least a part of the first opening 51a in the horizontal direction, the operating portion 24 is sided with respect to the pedestal portion 44 and the holding portion 40. It can be inserted horizontally from one direction. As a result, even when the holding portion 40, the connecting portion 42, and the pedestal portion 44 are integrated, the operating portion 24 can be easily attached to the holding portion 40. Therefore, it is possible to provide the drain plug device 10 which can be easily assembled with a simple configuration.

Further, in the drain plug device 10, the minimum lateral width W2 of the second opening 52a is larger than the maximum lateral width Ws of the operating portion 24. As a result, when the operating portion 24 is inserted into the pedestal portion 44 from the side, it is not necessary to push the pedestal portion 44 apart, and the assembling work can be made easier.

Further, in the drain plug device 10, the connecting portion 42a extends from one side end portion 51b of the first main body portion 51 toward the pedestal portion 44, and the connecting portion 42b extends from the other side end portion of the first main body portion 51. It extends from 51c toward the pedestal portion 44. As a result, when the operating portion 24 is inserted into the second opening 52a and then inserted into the first opening 51a from the side, the operating portion 24 is guided to the first opening 51a by the two connecting portions 42a and 42b. can do. As a result, the position of the operating portion 24 with respect to the first opening 51a can be easily adjusted, and the operating portion 24 can be easily inserted into the first opening 51a. Therefore, the assembly work can be made easier.

Further, in the drain plug device 10, the connecting portion 42a extends toward one side end portion 52b of the second main body portion 52, and the connecting portion 42b extends toward the other side end portion 52c of the second main body portion 52.

As a result, when the operating portion 24 is removed from the holding portion 40, the widths of the first opening 51a and the second opening 52a can be widened by pushing the side surfaces of the two connecting portions 42a and 42b outward. it can. As a result, the operating portion 24 can be easily removed from the holding portion 40, and the removal work can be simplified.

Further, in the drain plug device 10, one side end portion 52b of the second main body portion 52 projects from the connecting portion 42a toward the second opening portion 52a. Thereby, the width of the first opening 51a and the width of the second opening 52a can be further widened by putting a finger on the protruding portion of the side end portion 52b. Therefore, the work of removing the operating portion 24 can be made easier.

Further, in the drain plug device 10, the connecting portion 42c extends from the side of the first main body portion 51 opposite to the first opening 51a to the pedestal portion 44 toward the side opposite to the first opening 51a. As a result, when the operating portion 24 is inserted into the holding portion 40 from the side, a force is applied to the holding portion 40 so as to bring the holding portion 40 closer to the pedestal portion 44 located on the opposite side of the first opening 51a. Even if it is done, it is possible to prevent the pedestal portion 44 from being deformed. When the pedestal portion 44 is deformed, the relative positions of the holding portion 40 and the pedestal portion 44 are displaced, the plug lid 20 cannot be arranged at a desired position, and the watertightness between the plug lid 20 and the drain port 102a is lowered. There is a possibility that it will end up. In this drain plug device 10, since the connecting portion 42c extends to the pedestal portion 44 toward the side opposite to the first opening 51a, even if the above force acts on the holding portion 40 and the pedestal portion 44, the connecting portion 42c is connected. The portion 42c can maintain the relative positional relationship between the holding portion 40 and the pedestal portion 44. Therefore, it is possible to suppress a decrease in watertightness between the plug lid 20 and the drain port 102a.

7 (a) and 7 (b) are a perspective view and a top view showing a modified example of the attachment member according to the embodiment.
As shown in FIGS. 7 (a) and 7 (b), the pedestal portion 44 of the attachment member 26a further has a slit portion 54. The same reference numerals are given to those having substantially the same functions and configurations as those of the above-described embodiment, and detailed description thereof will be omitted.

The slit portion 54 divides the second main body portion 52 in the circumferential direction. The pedestal portion 44 has, for example, a plurality of slit portions 54. In this example, the pedestal portion 44 has two slit portions 54 of the slit portions 54a and 54b. The second opening 52a is provided between the plurality of connecting portions 42a and 42b. The slit portion 54a is provided between a plurality of connecting portions 42a and 42c separate from the second opening 52a. Similarly, the slit portion 54b is provided between a plurality of connecting portions 42b and 42c different from the second opening 52a.

As described above, in this example, the pedestal portion 44 is divided into three portions in the circumferential direction by the two slit portions 54a and 54b. The number of slit portions 54 is not limited to two, and may be one. For example, when the number of connecting portions 42 is four or more, three or more slit portions 54 may be provided. One slit portion 54 is provided between two adjacent connecting portions 42. Further, as described above, the second opening 52a is provided between the two connecting portions 42. Therefore, when the number of connecting portions 42 is M, the maximum number of slit portions 54 is M-1.

In the attachment member 26a, the first opening 51a and the second opening 52a can be more easily expanded by dividing the second main body 52 in the circumferential direction by the slit 54. Therefore, the work of assembling and removing the operating portion 24 can be made easier.

8 (a) and 8 (b) are a perspective view and a front view showing a modified example of the attachment member according to the embodiment.
As shown in FIGS. 8A and 8B, in the attachment member 26b, the first opening 51a is continuous from the lower end to the upper end of the first main body 51, and is the first region R1 and the second. It has a region R2 and. The first region R1 is a portion that allows the operating portion 24 to be inserted horizontally into the first main body portion 51 from the side. The second region R2 is located above the first region R1. The width WA2 of the second region R2 is narrower than the width WA1 of the first region R1. As a result, the second region R2 suppresses the actuating portion 24 inserted into the first main body 51 from coming off from the first main body 51 at the upper part of the first main body 51.

For example, in order to clean the drain plug portion 12 and the drain port portion 102, the drain plug device 10 may be attached to the bathtub 100 and the pipe 200, and then the plug lid 20 may be removed. The stopper lid 20 is removed from the operating portion 24 by pulling it upward from the drain port portion 102 and pulling it out from the support shaft 24b of the operating portion 24. At this time, a user who is unfamiliar with the removal operation may apply a force to the stopper lid 20 and the support shaft 24b in the horizontal direction as well.

Therefore, for example, when the width of the first opening 51a is substantially constant from the lower end to the upper end as in the attachment member 26 of the above embodiment, when the stopper lid 20 is removed, the width is substantially constant. A force is applied in the direction in which the operating portion 24 comes out of the first main body 51, and there is a possibility that the upper part of the operating portion 24 will come out of the first main body 51.

In the state after the drain plug device 10 is attached to the bathtub 100 and the pipe 200, it is difficult to reinsert the operating portion 24 into the first main body portion 51, which causes an extra effort for the user and the like. Further, for example, if the stopper lid 20 is forcibly attached with the upper portion of the operating portion 24 pulled out from the first main body portion 51, the stopper lid 20 cannot be arranged at a desired position, and the stopper lid 20 and the drain port 102a become There is a possibility that the watertightness will decrease.

On the other hand, in the attachment member 26b, the first opening 51a has the first region R1 and the second region R2, and the width WA2 of the second region R2 located above the first region R1 is the first. It is narrower than the width WA1 of the 1 region R1 and suppresses the actuating portion 24 inserted into the first main body portion 51 from coming off from the first main body portion 51.

As a result, in the attachment member 26b, a force is applied in the direction in which the operating portion 24 comes out of the first main body portion 51 after the drain plug device 10 is attached to the bathtub 100 and the pipe 200, for example, when removing the plug lid 20. Even so, it is possible to prevent the upper portion of the operating portion 24 from coming off from the first main body portion 51. For example, it is possible to suppress the trouble of reinserting the operating portion 24 into the first main body portion 51 and improve the usability of the drain plug device 10.

9 (a) and 9 (b) are perspective views showing a modified example of the attachment member according to the embodiment.
As shown in FIGS. 9A and 9B, in the attachment member 26c, the upper end of the first opening 51a is located below the upper end of the first main body 51. That is, in the attachment member 26c, the first opening 51a does not extend to the upper end of the first main body 51. The first main body 51 has a continuous portion 51d that is continuous with both side portions of the first opening 51a of the first main body 51 above the first opening 51a. The continuous portion 51d suppresses the actuating portion 24 inserted into the first main body portion 51 from coming off from the first main body portion 51.

As a result, in the attachment member 26c as well, after the drain plug device 10 is attached to the bathtub 100 and the pipe 200, a force is applied in the direction in which the operating portion 24 comes out of the first main body portion 51, as in the above attachment member 26b. Even so, it is possible to prevent the upper portion of the operating portion 24 from coming off from the first main body portion 51. The usability of the drain plug device 10 can be improved.

Further, the first main body 51 further has a recess 51e. The recess 51e is provided at a position different from that of the first opening 51a in the circumferential direction. The recess 51e is provided, for example, on the side opposite to the first opening 51a. The recess 51e is recessed downward from the upper end of the first main body 51. The recess 51e extends, for example, to the vicinity of the upper end of the case 24a of the operating portion 24. When the lower end of the recess 51e is located above the upper end of the case 24a, the distance between the lower end of the recess 51e and the upper end of the case 24a is, for example, 2 mm or less. It is preferable that the lower end of the recess 51e extends at the same height as the upper end of the case 24a or below the upper end of the case 24a, for example.

As a result, even when the continuous portion 51d is provided, it is possible to prevent water from accumulating in the upper portion of the operating portion 24 (the space surrounded by the operating portion 24 and the first main body portion 51). For example, it is possible to prevent the upper part of the operating portion 24 from being easily contaminated.

10 (a) and 10 (b) are a perspective view and a top view showing a modified example of the attachment member according to the embodiment.
As shown in FIGS. 10A and 10B, the attachment member 26d has a holding portion 40 and a plurality of supporting portions 46. The plurality of support portions 46 are integrated with the holding portion 40, extend outward from the holding portion 40, and support the holding portion 40 on the drain port 102a or the pipe 200.

In this example, the attachment member 26d has three support portions 46a-46c. The support portion 46a, which is one of the plurality of support portions 46, extends outward from one side end portion 51b of the first main body portion 51. The support portion 46b, which is another one of the plurality of support portions 46, extends outward from the other side end portion 51c of the first main body portion 51. Thereby, when the operating portion 24 is inserted into the first opening 51a from the side, the operating portion 24 can be guided to the first opening 51a by the two support portions 46a and 46b. As a result, the position of the operating portion 24 with respect to the first opening 51a can be easily adjusted, and the operating portion 24 can be easily inserted into the first opening 51a from the side. Therefore, the assembly work can be made easier.

Further, the support portion 46c extends outward from the side of the first main body portion 51 opposite to the first opening 51a toward the side opposite to the first opening 51a. Hereinafter, since the configuration of the plurality of support portions 46 is substantially the same as the configuration of the plurality of connecting portions 42 of each of the above embodiments, detailed description thereof will be omitted.

In this way, the holding portion 40 may be attached to the drain port 102a or the pipe 200 by a plurality of support portions 46 without providing the pedestal portion 44. Also in the attachment member 26d, it is possible to provide the drain plug device 10 which can be easily assembled with a simple configuration as in each of the above-described embodiments.

A protruding portion 48 extending in the circumferential direction is provided at an end portion of the support portion 46 opposite to the holding portion 40. Thereby, for example, the contact area of the drainage port 102a or the inner peripheral surface of the pipe 200 can be increased, and the attachment member 26d can be attached to the drainage port 102a or the pipe 200 more stably.

In the attachment member 26d, for example, by mounting the protruding portion 48 of each support portion 46 on the mounting portion 220, the downward movement in the pipe 200 is restricted. Further, in the attachment member 26d, each protruding portion 48 is pressed downward by the drainage port member 22, so that the upward movement is restricted. Each protruding portion 48 is housed in the first storage space 221 in the pipe 200, for example, and is sandwiched between the mounting portion 220 and the drain port member 22. In other words, the structure of the protruding portion 48 is a structure in which the length of the portion of the pedestal portion 44 divided by the slit portion 54 in the circumferential direction is shortened.

In each of the above embodiments, the bathtub 100 is shown as a water tank to which the drain plug device 10 is attached. The water tank is not limited to the bathtub 100, and may be, for example, a washbasin (washbasin) of a vanity. The water tank to which the drain plug device 10 is attached may be any water tank capable of discharging the water stored inside from the drain port.
