  The inflow portion 31 is a portion into which drainage from the drainage port 102 flows, and has a cylindrical shape extending in the vertical direction. A female screw portion 31 </ b> A capable of screwing the male screw portion 23 is formed on the inner periphery of the upper end portion of the inflow portion 31. The drain pipe 3 is connected to the drain port member 21 by screwing the male thread portion 23 into the female thread portion 31 </ b> A and sandwiching the bottom wall portion 101 by the upper end portions of the flange portion 22 and the inflow portion 31. And is attached to the bathtub 100. In the present embodiment, an annular seal member 8 formed of an elastically deformable material is interposed between the upper end surface of the inflow portion 31 and the bathtub 100, and the drain port is provided by the seal member 8. The leakage of water from between the member 21 and the drainage pipe 3 (pipe 2) and the bathtub 100 is prevented.

  The folded portion 32 has a cylindrical shape extending obliquely upward from the lower end portion of the inflow portion 31. And the waste_water | drain which flowed into the inflow part 31 through the drain outlet 102 can be stored in the inside of the bending part which consists of the inflow part 31 and the folding | returning part 32 as sealing water. That is, in this embodiment, the inflow part 31 and the folding | returning part 32 comprise the sealing part 34 which can store sealing water.

  The orthogonal portion 33 has a cylindrical shape extending from the upper end portion of the folded portion 32 in a direction (horizontal direction) orthogonal to the inflow portion 31. In the present embodiment, the sealed water is stored in the sealed portion 34 up to the sealed surface 35 having the same height as the boundary between the folded portion 32 and the orthogonal portion 33 (in FIG. 1 and the like, the sealed surface 35 is indicated by a two-dot chain line). It is possible.

  In addition, the cylindrical attachment tube 9 projects outward from the inflow portion 31. The attachment tube 9 is formed to project from the outer periphery of the inflow portion 31 in the horizontal direction, and its own internal space communicates with the internal space of the inflow portion 31. Further, a pair of mounting holes (not shown) having a rotationally symmetric shape with respect to the central axis of the mounting tube 9 are formed at the end portion of the mounting tube 9 that is located on the opposite side of the inflow portion 31. ing.

  The plug lid side mechanism portion 4 is attached in a state of being inserted through the attachment tube 9 and includes a rotation portion 41, a movement direction conversion portion 42, and a case member 43.

  The rotating portion 41 protrudes from the inside of the case member 43 to the outside, and this protruding portion is inserted through the attachment tube 9. Further, the rotation part 41 is rotatable about a rotation axis that is coaxial with the central axis of the attachment tube 9. Furthermore, the rotating part 41 has a rod-like support part 44 protruding into the inflow part 31 on the outer peripheral side (the outer peripheral side of the end face located on the inner space side of the inflow part 31) on the axial end face. .

  The support portion 44 has a cylindrical shape and is relatively short so that the tip thereof does not reach the central axis of the drain pipe 3 (inflow portion 31). Moreover, the support part 44 moves up and down while rotating by the rotation part 41 rotating.

  The movement direction conversion unit 42 is connected to a transmission member (not shown) made of, for example, a wire that reciprocates according to the displacement of a predetermined operation member (for example, an operation button or an operation handle). The reciprocating motion is converted into the rotational motion of the rotational portion 41. The movement direction conversion unit 42 is, for example, a reciprocally movable rack in which the transmission member is connected and a plurality of teeth are formed, meshed with the rack, and coaxial with the rotation unit 41 And a rotatable gear (pinion) fixed by the. In such a movement direction conversion unit 42, the rack reciprocates as the transmission member reciprocates, the gear rotates, and the rotation unit 41 rotates as the gear rotates. The support portion 44 moves up and down while rotating. In addition, the structure of the motion direction conversion part 42 in this embodiment is an illustration, Comprising: The structure of the motion direction conversion part 42 can be changed suitably.

In the present embodiment, the case member 43 includes a plurality of claw portions (not shown) extending in parallel with the rotation axis of the rotation portion 41, and the claw portions are the attachment hole portions of the attachment tube 9. Is inserted into the mounting tube 9 and is locked to the mounting tube 9. Thereby, the stopper lid side mechanism part 4 is in a state of being attached to the attachment pipe 9. In addition, the attachment method of the plug lid side mechanism part 4 with respect to the attachment pipe | tube 9 can be changed suitably, For example, it is good also as attaching the plug lid side mechanism part 4 with a quick fastener, a screw, etc.

  The plug lid 6 includes a disk-shaped plug lid main body portion 61 made of resin or the like, and a packing portion 62 attached to the plug lid main body portion 61. The packing portion 62 is formed in an annular shape by an elastically deformable material (for example, rubber, resin, etc.), and is fitted into the outer periphery of the attached portion 63 provided on the outer peripheral side of the back surface of the plug lid main body portion 61. It is supposed to be in a state.

  The water flow member 7 is arranged in a state that can move up and down in the pipe 2, and as shown in FIG. 2 (only a part of a support shaft 72 </ b> A described later is shown in FIG. 2), An upper component 72 is provided.

  The lower component 71 has a cylindrical shape, is disposed in the pipe 2 along the inner peripheral surface of the pipe 2, and is a part placed on the support portion 44. The water passing member 7 is supported in the pipe 2 by the support portion 44 because the lower component portion 71 is placed on the support portion 44.

  Further, in the present embodiment, the lower component 71 is formed with an insertion portion 71A penetrating from the inner periphery to the outer periphery thereof, and the support portion 44 is inserted into the insertion portion 71A. (See Fig. 1 etc.). A portion of the lower component 71 that forms the inserted portion 71 </ b> A is placed on the support portion 44. Moreover, in this embodiment, the lower structure part 71 is made into the state which cannot be pulled out from the piping 2, or it is difficult to pull out by the support part 44 being penetrated with respect to 71 A of to-be-inserted parts.

  In addition, the lower component portion 71 includes a cylindrical lower extension portion 71 </ b> B that extends downward from a portion in contact with the support portion 44. In the present embodiment, the downward extending portion 71B is relatively long along its own axial direction (for example, has a length that is half or more of the minimum inner diameter of the portion of the pipe 2 where the water flow member 7 is disposed). )

  Further, the lower component 71 is provided with a hook-like portion 71 </ b> C projecting outward at the upper portion thereof. As a result, the upper end surface of the lower component 71 has a relatively large area. In the present embodiment, the upper end surface of the lower component 71 is a flat surface extending in the horizontal direction.

  The upper component 72 is disposed above the lower component 71 and is configured to be separable from the lower component 71. The upper component 72 includes a rod-like support shaft 72A, a mounting portion 72B positioned outside the support shaft 72A, and a plurality of arm portions 72C (not shown in FIG. 1 and the like). The arm portion 72C connects the inner periphery of the placement portion 72B and the outer periphery of the support shaft 72A.

  The support shaft 72A is disposed substantially at the center of the pipe 2 and has a rod shape extending in the vertical direction. The support shaft 72 </ b> A supports the plug lid 6 by attaching the upper end of the support shaft 72 </ b> A to the center of the back surface of the plug lid 6. Thereby, the plug lid 6 is directly attached to the upper component 72 (a supported state). The stopper lid 6 may be indirectly attached to the upper constituent portion 72 (the stopper lid 6 is indirectly supported by the upper constituent portion 72).

  Furthermore, the support shaft 72A includes a shock absorber spring 72S (see FIG. 1 and the like) that can be expanded and contracted along the axial direction. When the support shaft 72A is pressed from above, the support shaft 72A It is designed to compress and deform along the axial direction. Accordingly, when a downward force is applied to the support shaft 72A, such as when a heavy object is placed on the plug lid 6 when the drain port 102 is in the open state, the water flow member 7 and the support portion 44 are applied. It is possible to prevent damage such as.

  The mounting portion 72 </ b> B has an annular shape, and the lower end surface thereof has a flat surface shape that is substantially the same shape as the upper end surface of the lower component portion 71.

  In the water passing member 7 configured as described above, when the support portion 44 moves upward, the lower component portion 71 moves upward, and the placement portion 72B is placed on the upper end surface of the lower component portion 71. In the placed state, the upper component 72 moves up. Thereby, the stopper lid 6 moves upward together with the support shaft 72A, and the packing portion 62 is separated from the bottom wall portion 101, so that the drain port 102 is opened (see FIG. 3). On the other hand, when the support part 44 is moved downward, the lower component part 71 is moved downward, and as a result, the upper component part 72 is moved downward. As a result, the stopper lid 6 moves downward together with the support shaft 72A, and the entire outer peripheral portion of the packing portion 62 contacts the bottom wall portion 101, thereby closing the drainage port 102 (see FIG. 1).

  However, in the present embodiment, when the drain port 102 is in the open state, the lower end surface of the mounting portion 72B is placed on the upper end surface of the lower component 71, while the support portion 44 is at the lowest position. Is disposed (when the drain port 102 is in a closed state), the mounting portion 72B is separated from the upper end surface of the lower component 71 (floating state). . As a result, when the drain port 102 is closed, the packing portion 62 can be brought into contact with the bottom wall portion 101 more reliably, and good water tightness can be obtained.

  In addition, in the present embodiment, as shown in FIGS. 1 and 3, at least the mounting portion 72 </ b> B among the upper constituent portions 72 is when the drain port 102 is in an open state and when the drain port 102 is in a closed state. Both of them are located above the sealing surface 35. On the other hand, at least a part (in this embodiment, the lower portion) of the lower component 71 has a sealed surface 35 both when the drain port 102 is open and when the drain port 102 is closed. It is supposed to be located below.

  As described above in detail, according to this embodiment, the water flow member 7 includes the upper component 72 and the lower component 71, and the upper component 72 attached to the plug lid 6 is Separation from the component 71 is possible. Accordingly, by pulling the stopper lid 6 upward, the upper component 72 can be easily pulled out from the pipe 2 in a state of being separated from the lower component 71. Thereby, the plug lid 6 and the upper component 72 can be easily removed.

  By the way, in this embodiment, since at least one part of the lower side structure part 71 is located below the sealing surface 35 both when the drain port 102 is an open state and when the drain port 102 is a closed state. , Dirt tends to adhere to the lower component 71. For this reason, if the water passage member 7 is entirely removed from the pipe 2 when the stopper lid 6 and the like are pulled up, the water passage member 7 (lower component 71) is removed when the stopper lid 6 and the like are lifted. ) May be exposed and may cause discomfort to the user.

  In this regard, in the present embodiment, at least the mounting portion 72B of the upper component 72 is above the sealing surface 35 both when the drain port 102 is in the open state and when the drain port 102 is in the closed state. It is supposed to be located in Therefore, it is possible to always suppress the placement portion 72B that is particularly easy to visually check from being soaked in the sealed water, and it is possible to extremely effectively prevent dirt from adhering to the placement portion 72B. As a result, it is possible to more reliably prevent the dirt from being exposed when the stopper lid 6 is removed, and more reliably to prevent the user from feeling uncomfortable.

  Furthermore, even if the water flow member 7 is inclined with respect to the pipe 2 due to the upward movement of the support portion 44 by providing the downward extension portion 71B, the downward extension portion 71B (particularly the support portion 44) The part located vertically below) can be more reliably brought into contact with the pipe 2, and the further inclination of the water passage member 7 can be effectively suppressed. As a result, it is possible to suppress the inclination of the support shaft 72A and the plug lid 6 with respect to the pipe 2, and when the drain outlet 102 of the bottom wall portion 101 is closed, it is sealed by the plug lid 6 (packing portion 62). It can suppress that the center axis | shaft of the stopper lid 6 shift | deviates largely with respect to the center of a site | part (sealed site | part), and can acquire favorable watertightness by extension. In addition, it is possible to ensure a good aesthetic when the drain port 102 is opened.

In addition, since the bowl-shaped part 71C is provided in the upper part of the lower structure part 71, without reducing the area of the water flow part located inside the lower structure part 71, the lower structure part 71 It is possible to secure a larger contact area of the mounting portion 72B with respect to the upper portion. Thereby, the upper side structure part 72 can be supported in the more stable state by the lower side structure part 71, preventing the fall of drainage performance.
[Second Embodiment]
Next, the second embodiment will be described focusing on the differences from the first embodiment. In the first embodiment, at least the mounting portion 72B of the upper component portion 72 is positioned above the sealing surface 35 both when the drain port 102 is in the open state and when the drain port 102 is in the closed state. Is configured to do. On the other hand, in the second embodiment, as shown in FIGS. 4 and 5, for example, by extending the inflow portion 31 further downward, the entire upper constituent portion 72, that is, the support portion 72A, the mounting portion The portion 72B and the arm portion 72C are configured to be positioned above the sealing surface 35 both when the drain port 102 is in the open state and when the drain port 102 is in the closed state.

  As described above, according to the second embodiment, it is possible to prevent the upper component 72 from being immersed in the sealed water regardless of whether the drain port 102 is in the open state or the closed state. Contamination can be remarkably suppressed. As a result, it is possible to very effectively prevent the user from feeling uncomfortable when the stopper lid 6 is removed.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the first embodiment, at least the mounting portion 72B of the upper component portion 72 is more than the sealing surface 35 both when the drain port 102 is in the open state and when the drain port 102 is in the closed state. It is supposed to be located above. On the other hand, you may comprise so that at least mounting part 72B among the upper structure parts 72 may be located above the sealing surface 35 at least when the drain outlet 102 is in an open state.

Relative to the part 31). On the other hand, as shown in FIG. 6 (in FIG. 6, the water-permeable member 7 and the like are not shown), it protrudes toward the lower component 71 side with respect to the inner peripheral surface of the pipe 2 (inflow portion 31). A plurality of inwardly projecting protrusions 31 </ b> A may be provided, and the inwardly projecting protrusions 31 </ b> A may constitute the lower movement restricting means 11 that restricts the relative movement of the lower component 71 with respect to the pipe 2 along the horizontal direction. . In this case, the lower movement restricting means 11 can more reliably maintain the relative positional relationship between the pipe 2 and the lower component 71 along the horizontal direction in a normal state. Therefore, when the lower component 71 moves up and down, it is possible to more reliably prevent the upper component 72 from being moved so as to be moved by the lower component 71 by moving in the horizontal direction. . Thereby, when the drain port 102 is opened, a better aesthetic appearance can be obtained. Moreover, the shift | offset | difference of the center of the to-be-sealed site | part in the bathtub 100 and the center axis | shaft of the stopper lid 6 can be suppressed more effectively, and more favorable water-tightness can be acquired.

By configuring the lower movement restricting means 11 and 12 with the inward protrusion 31A and the outward protrusion 71D as described above, the contact area between the pipe 2 and the lower component 71 can be made relatively small. When the lower component 71 moves up and down, the resistance generated between the lower component 71 and the pipe 2 can be reduced. As a result, the lower component 71 can be moved more smoothly while maintaining the relative position of the lower component 71 with respect to the pipe 2 in an appropriate state.

  In addition, you may comprise a lower side movement control means by providing both the inward protrusion 31A and the outward protrusion 71D. Further, the inward projection and the outward projection may not extend in the axial direction of the pipe 2 or the lower component 71.

  (C) In the above-described embodiment, the upper end surface of the lower component portion 71 and the lower end surface of the placement portion 72B have a flat surface extending in the horizontal direction, and the upper component portion 72 and the piping located on the outer periphery thereof. When a gap is formed between the upper structure portion 72 and the lower structure portion 71, the upper structure portion 72 can move relative to the lower structure portion 71 along the horizontal direction. On the other hand, as shown in FIGS. 8 to 10 (note that FIG. 9 is an enlarged cross-sectional view in the imaginary circle indicated by a two-dot chain line in FIG. 8), the lower component along the horizontal direction The upper movement restricting means 14 for restricting the relative movement of the upper component 72 with respect to 71 may be provided. The upper movement restricting means 14 is provided, for example, on the upper surface of the lower component 71, and is provided on the upper end inclined portion 71E that gradually decreases toward the central axis side of the pipe 2 and on the lower surface of the placement portion 72B. You may comprise by the lower end inclination part 72E which becomes low gradually toward the center axis side of No.2. By the upper movement restricting means 14, the relative positional relationship between the lower component 71 and the upper component 72 along the horizontal direction can be more reliably maintained in a normal state. Thereby, the shift | offset | difference of the center of the to-be-sealed site | part in the bathtub 100 and the center axis | shaft of the stopper lid 6 can be suppressed more effectively, and the further outstanding watertightness can be acquired.

  Further, for example, as shown in FIG. 11 and FIG. 12 (where FIG. 12 is an enlarged cross-sectional view in a virtual circle indicated by a two-dot chain line in FIG. 11), it is provided at the upper part of the lower component 71. The upper movement restricting means 15 is configured by the cylindrical outer cylinder portion 71F and the cylindrical inner cylinder portion 72F provided at the lower portion of the mounting portion 72B and disposed on the inner periphery of the outer cylinder portion 71F. May be. In addition, the cylindrical outer cylinder part provided in the lower part of the mounting part 72B, the cylindrical inner cylinder part provided in the upper part of the lower structure part 71 arrange | positioned in the inner periphery of the said outer cylinder part, The upper movement restricting means may be configured by.

  (D) In the above embodiment, the placement portion 72B is configured to be placed simply on the upper portion of the lower component portion 71 when the drain port 102 is in the open state. On the other hand, as shown in FIG. 13 and FIG. 14 (where FIG. 14 is an enlarged cross-sectional view in a virtual circle indicated by a two-dot chain line in FIG. 13), for example, While providing the latching | locking part 72G, the to-be-latched part 71G is provided in the upper part of the lower side structure part 71, and the upper side structure part 72 is a lower side structure by latching the latching | locking part 72G to the to-be-latched part 71G. You may comprise so that the mounting part 72B may be mounted with respect to the upper part of the lower structure part 71 in the state latched to the part 71 so that attachment or detachment was possible. In this case, a force is applied to the plug lid 6 or the like so as to separate the upper component 72 from the lower component 71, and the locked state is released to release the upper component from the lower component 71. 72 is separated. That is, the upper component part 72 may be easily separated from the lower component part 71 by lifting the stopper lid 6 or the like, or by applying a force in a direction of pulling away from the lower component part 71. It may be separated from the lower component 71.

  (E) In the above embodiment, the support portion 44 protrudes from the axial end surface of the rotation portion 41 and is configured to move up and down while rotating as the rotation portion 41 rotates. However, the configuration is not limited to this. Therefore, for example, as shown in FIG. 15, the support portion 45 protrudes from the outer periphery of the rotation portion 46 that can be rotated by a rotation shaft that extends in the horizontal direction. You may comprise so that the water flow member 7 supported by this may move up and down.

  (F) In the above embodiment, the pipe 2 includes the drain port member 21 and the drain pipe 3, but the drain pipe 3 is directly fixed to the bathtub 100 without using the drain port member 21. May constitute the pipe 2 only by the drain pipe 3.

  Moreover, the shape of the sealing part 34 in the said embodiment is an illustration, Comprising: As long as sealing water can be stored, the shape of the sealing part 34 is not specifically limited.

  (G) In the above embodiment, since the support portion 44 is configured to move as the turning portion 41 rotates, the support portion 44 moves along the circumferential direction of the pipe 2 while moving up and down. Therefore, when moving the support portion 44 to move the lower component 71 up and down, the lower component 71 may move relative to the pipe 2 along the circumferential direction of the pipe 2. On the other hand, for example, as shown in FIG. 16, the inner peripheral surface of at least a portion where the lower component 71 is disposed in the pipe 2 (inflow portion 31) has a non-circular cross section, and the lower component The outer peripheral surface of 71 has a shape that is arranged along the inner peripheral surface of the pipe 2 (inflow portion 31), and the lower rotational movement restricting means 17 composed of the inner peripheral surface of the pipe 2 and the outer peripheral surface of the lower component 71. The relative movement of the lower component 71 with respect to the pipe 2 along the circumferential direction of the pipe 2 may be restricted. In this case, it is possible to prevent the lower component portion 71 from rotating so as to rotate with respect to the pipe 2 as the support portion 44 moves up and down. Thereby, the lower side structure part 71 can be moved up and down more smoothly, and operativity can be improved more. Moreover, since it can suppress effectively that the upper structure part 72 and the stopper lid 6 move so that it may rotate, when the drain outlet 102 is opened and closed (while the drain outlet 102 is being opened and closed), the stopper lid 6 is more twisted. It can be reliably moved only in the vertical direction. Thereby, the appearance can be further improved. In FIG. 16, the drain pipe 3 is directly fixed to the bottom wall portion 101 without using the drain port member 21, and the drain pipe 3 constitutes the pipe 2, and the plug lid 6 and the upper constituent portion 72 are arranged. The state removed from the pipe 2 is shown.

  In addition, as shown in FIG. 17, a protrusion 31 </ b> B extending along the axial direction of the pipe 2 is provided on the inner periphery of the pipe 2 (inflow part 31), and the periphery of the pipe 2 is provided on the outer periphery of the lower component part 71. An adjacent arrangement part 71H arranged in a state adjacent to the protrusion 31B along the direction is provided, and along the circumferential direction of the pipe 2 by the lower rotational movement restricting means 18 including the protrusion 31B and the adjacent arrangement part 71H. The relative movement of the lower component 71 with respect to the pipe 2 may be restricted.

  Furthermore, while providing the groove part extended along the axial direction of the pipe 2 in the inner periphery of the piping 2 (inflow part 31), the protrusion-like adjacent arrangement | positioning part arrange | positioned at the said groove part is provided in the outer periphery of the lower side structure part 71. The relative movement of the lower component 71 with respect to the pipe 2 along the circumferential direction of the pipe 2 may be restricted by the lower rotational movement restricting means that is provided and includes the groove portion and the adjacent arrangement portion.

  In the case where the lower rotational movement restricting means is provided, when the support portion 44 moves up and down while moving along the circumferential direction of the pipe 2 as in the above embodiment, for example, as shown in FIG. It is necessary to prevent the movement of the support portion 44 from being restricted by sufficiently increasing the width of the insertion portion 71A.

  (H) In the above embodiment, the mounting portion 72B is separated from the lower component 71 when the drain port 102 is closed. However, the drain port 102 is also closed. You may comprise so that the mounting part 72B may be mounted with respect to the lower structure part 71. FIG.

  (I) In the above-described embodiment, the lower component 71 is not pulled out or difficult to pull out from the pipe 2. For example, the lower end surface of the lower component 71 is placed on the support 44. Or the lower component 71 may be pulled out of the pipe 2 by pulling the lower component 71 upward so that the support portion 44 can be removed from the inserted portion 72A. . In this case, the upper component 72 is simply placed on the lower component 71, and the upper component 72 can be easily moved from the lower component 71 when the stopper lid 6 is pulled up. It is preferable to separate them.

  (J) In the embodiment described above, the placement portion 72B has an annular shape, but the shape of the placement portion 72B is not limited to an annular shape and can be changed as appropriate. For example, a mounting portion (for example, a mounting portion having a shape that extends the arm portion 72C toward the outer peripheral side) is provided on the distal end portion (outer peripheral end portion) of the arm portion 72C. The arm portion 72C and the placement portion may be configured to have a cross shape in plan view.

  (K) In the above embodiment, the lower extension 71B has a cylindrical shape, but the lower extension may be a non-cylindrical shape. For example, it is good also as providing a downward extension part only in the position of the downward direction of the part which contacts the support part 44 in the lower side structure part 71, and its vicinity. By providing the downward extension at this position, when the water passing member 7 is inclined with respect to the pipe 2 as the support part 44 is moved upward, the downward extension is brought into contact with the pipe 2 when the inclination is smaller. Can be made. Therefore, the inclination of the stopper lid 6 and the like can be effectively suppressed.

  (L) In the above embodiment, the drain lid 102 is closed by the stopper lid 6 (packing portion 62) coming into contact with the bottom wall portion 101. However, the stopper lid 6 (packing portion 62) is You may comprise so that the drain port 102 may be closed by contacting the drain port member 21.
