  However, when providing the plug lid driving mechanism inside the pipe, it is difficult to draw out the plug lid driving mechanism and the transmission member from the pipe that cannot be reached, which is troublesome and troublesome. In addition, when replacing the lid cover drive mechanism in the event of a malfunction of the lid cover drive mechanism, after removing the plug lid drive mechanism and piping in the reverse procedure of the installation work, An operation of reattaching the stopper lid driving mechanism is required. Therefore, it is inferior to attachment workability and maintainability. Furthermore, when pulling out the stopper cover driving mechanism and the transmission member from the pipe during the mounting operation or the replacement operation, the mounting operator cannot visually recognize the state of most of the release wire. For this reason, when pulling out the plug lid driving mechanism or the like, there is a risk that the member such as the release wire may be damaged, such as the transmission member being cut or bent.

  In addition, in the piping, the release wire is in a state where it is bridged to the center of the piping, which makes it easy for hair, dust, etc. to be caught on the release wire, which in turn tends to cause clogging of the piping. There is a concern that In addition, it is conceivable that the presence of the release wire may hinder the cleaning of piping, traps and the like located below the release wire.

  The present invention has been made in view of the above circumstances, and its purpose is to dramatically improve the mounting workability and maintainability, and more reliably prevent the member from being damaged during the mounting work. An object of the present invention is to provide a drain plug device that can be realized.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

The stopper cover driving mechanism is configured to insert the rotation shaft from the outside of the pipe into the mounting cylinder with the one end of the release wire attached, and to engage the locking portion with the engagement portion. The drain plug device is configured to be attachable to the pipe by locking the stopper.

  According to the above means 1, after the release wire is attached to the stopper cover driving mechanism, the stopper cover driving mechanism can be easily attached from the outside of the pipe to the pipe (mounting cylinder). Accordingly, the work related to the attachment and replacement of the plug lid driving mechanism can be made extremely easy, and the attachment workability and maintainability can be greatly improved. In addition, it is not necessary to pull out the stopper cover driving mechanism or the transmission member from the inside of the pipe at the time of mounting work, and the work can be performed while checking the state of the release wire. Therefore, it can prevent more reliably that a member, such as a release wire, will be damaged.

  In addition, according to the means 1, the support protrusion supports the annular outer peripheral wall portion arranged along the inner peripheral surface of the pipe (pipe main body portion). The protrusion amount of the support protrusion with respect to the inner peripheral surface can be made extremely small. Accordingly, it is difficult for dust and the like to adhere to the support protrusions, and clogging of the piping can be effectively suppressed. In addition, piping, traps, and the like located behind (below) the support protrusions can be cleaned relatively easily, and the cleanability can be improved.

Mean 2. The mounting cylinder has a mounting hole through which the locking portion can be inserted,
The stopper cover driving mechanism is inserted into the mounting cylinder from the outside of the pipe with the one end of the release wire attached, and is locked to the mounting hole. It is configured to be attachable to the pipe by inserting the part, rotating the case member relative to the pipe, and locking the locking part to the locked part. The drain plug device according to means 1.

According to the means 2, basically the same operational effects as those of the means 1 are achieved.

Means 3 . The stopper lid driving mechanism has an elastically deformable annular sealing member provided on the outer periphery of the rotating shaft,
When the stopper cover driving mechanism is attached to the pipe, the sealing member is watertight between the rotating shaft and the mounting cylinder or between the rotating shaft and the mounting cylinder. 3. The drain plug device according to the means 1 or 2 , characterized in that the space between the contacting intervening members is kept watertight.

According to the above means 3 , when the stopper cover driving mechanism is attached to the pipe, the sealing member provided in the stopper cover driving mechanism causes the gap between the rotating shaft and the mounting cylinder portion, etc. positioned around it. Keeps watertight. Therefore, it is not necessary to perform a separate operation in order to ensure watertightness during the mounting operation, and the mounting workability and maintainability can be further improved.

Means 4 . The pivot axis is
A disk portion provided with the support protrusion;
Adjacent to the disk part, having a small diameter part whose outer diameter is smaller than the outer diameter of the disk part,
The stopper cover driving mechanism has a cylindrical interposition member in which the small-diameter portion is disposed on its inner periphery while being in watertight contact with the inner peripheral surface of the mounting cylinder portion,
4. The means 3 according to claim 3 , wherein the sealing member is in watertight contact with an inner peripheral surface of the interposition member and an outer peripheral surface of the small-diameter portion in a state where the stopper cover driving mechanism is attached to the pipe. Drain plug device.

  In order to secure a good drainage capacity when the drain outlet is opened, it is desirable to make the stroke of the stopper lid sufficiently large. The stroke amount of the plug lid corresponds to the amount of movement along the vertical direction of the support protrusion when the rotation shaft is rotated. Therefore, in order to increase the stroke amount of the plug lid, it is necessary to make the rotation shaft have a relatively large diameter and to increase the distance along the radial direction from the rotation center of the disk portion to the support protrusion.

  However, when the rotation shaft has a relatively large diameter along the axial direction, the sealing member provided on the outer periphery of the rotation shaft needs to have a large diameter. For this reason, the area of the contact portion between the rotation shaft and the mounting cylinder portion and the sealing member and the diameter of the contact portion are increased, and resistance when the rotation shaft is rotated is increased. If the resistance at the time of rotation increases, the operability and operational stability may be reduced.

In this regard, according to the means 4 , the sealing member is provided on the outer periphery of the small diameter portion of the rotation shaft. Accordingly, the sealing member can be made to have a relatively small diameter, and the area of the contact portion between the rotating shaft (small diameter portion) and the interposed member and the sealing member and the diameter of the contact portion can be made relatively small. . Thereby, the resistance at the time of rotating a rotating shaft can be made small, and even if the force applied to a displacement member is comparatively small, a rotating shaft can be rotated smoothly. As a result, operability and operational stability can be improved.

Further, according to the above means 4 , the disk portion on which the support protrusion is provided can have a relatively large diameter, and as a result, a sufficient distance along the radial direction from the center of rotation of the disk portion to the support protrusion can be obtained. Can be big. Therefore, the amount of movement of the support protrusion along the vertical direction when the rotation shaft is rotated, and thus the stroke amount of the plug lid, can be sufficiently increased. As a result, it is possible to ensure good drainage capacity when the drain outlet is opened.

Means 5 . The drain plug device according to any one of means 1 to 4 , wherein the stopper cover driving mechanism includes a rotation range defining means for defining a rotatable range of the rotation shaft.

  In order to accurately set the stroke amount (vertical movement amount) of the plug lid as a target set amount, it is conceivable to provide a rotation range defining means for defining a rotatable range of the rotation shaft. In providing the rotation range defining means, it is conceivable to provide the rotation range defining means in either the operating device or the plug lid driving mechanism. Here, when the rotation range defining means is provided in the operating device, the rotatable range of the rotation shaft is defined via the transmission member. For this reason, the pivotable range of the pivot shaft slightly deviates from the target range, and as a result, the stroke amount of the plug lid may not be set with high accuracy.

In this regard, according to the means 5 , the rotation range defining means is provided in the stopper cover driving mechanism, and the rotatable range of the rotation shaft is defined without using the transmission member. For this reason, the pivotable range of the pivot shaft can be defined more accurately and accurately. As a result, the stroke amount of the stopper lid can be accurately set to the target.

Means 6 . At least one of the transmission member, the tube member, and the stopper cover driving mechanism is configured such that when a force along at least one of the compression direction and the extension direction is applied to the transmission member, the transmission member and the tube The drain plug device according to any one of means 1 to 5 , further comprising an overload prevention means for reducing a load applied to the member.

  As the “overload prevention means”, for example, the force applied to the transmission member or the tube member is absorbed by elastically deforming the transmission member when a force along the compression direction or the extension direction is applied to the transmission member. A spring member or a transmission member configured to be able to return to its original shape when an excessively large force is applied along the extension direction, while returning to the original shape when the application of the force is released. The tube member etc. which were comprised comparatively easily were mentioned.

  When the displacement member is displaced, the amount of reciprocation of the transmission member is determined by the support protrusions at a predetermined lower limit position (arrangement position when the drain outlet is closed) and a predetermined upper limit position (arrangement position when the drain outlet is opened). It is conceivable to set the minimum amount necessary to rotate the rotation shaft so that the rotation shaft moves from one of the two to the other of the two. However, in this case, when the displacement member is displaced, the transmission shaft cannot be sufficiently rotated due to a slight problem such as slight deformation of the transmission member. May not be placed at the upper limit position or the lower limit position. As a result, there is a risk that the closing of the drainage port may be hindered or the drainage capacity (water flow area) may be reduced when the drainage port is opened.

  Therefore, even if the transmission member is slightly deformed when the displacement member is displaced, the reciprocation amount of the transmission member is set to the minimum amount so that the rotation shaft can be sufficiently rotated. It is conceivable to set a larger value. However, in this case, when the displacement member is displaced and the transmission member is reciprocated, an overload is applied to the transmission member (the transmission member is excessively compressed / extended), and as a result, the transmission member Or the tube member may be damaged or deformed.

In this respect, according to the means 6 , the overload preventing means can more reliably prevent the transmission member and the tube member from being overloaded. Thereby, damage and a deformation | transformation in a transmission member or a tube member can be suppressed effectively.

Means 7 . The overload prevention means includes the transmission member and the transmission member both when a force along the compression direction is applied to the transmission member and when a force along the extension direction is applied to the transmission member. The drain plug device according to the means 6 , characterized in that the load applied to the tube member is reduced.

According to the means 7 , breakage or the like in the transmission member or the tube member can be further effectively suppressed.

Means 8 . The movement direction conversion unit is
A rack portion connected to one end of the transmission member, reciprocating with the reciprocation of the transmission member, and having a plurality of teeth formed along the reciprocation direction of the transmission member;
Any one of means 1 to 7 , further comprising: a gear portion that is provided coaxially with the rotation shaft, meshed with teeth of the rack portion, and rotatable with reciprocation of the rack portion. The drain plug device described.

According to the means 8 , the movement direction conversion unit can be realized with a relatively simple configuration. Accordingly, it is possible to suppress an increase in manufacturing cost and to reduce the size of the stopper cover driving mechanism.

The claw portion 61K includes a base portion 61L that is located on the base side and is formed relatively thin, and a locking portion 61M that protrudes outward from the tip portion of the base portion 61L (on the side opposite to the rotation shaft 63). I have.

  The base portion 61L has a convex portion 61N that slightly protrudes outward, and is formed to have a thickness that can pass through the narrow portion 71G.

  The locking portion 61M is formed to a thickness that cannot pass through the narrow portion 71G, but can pass through the wide portion 71F.

  When attaching the stopper cover driving mechanism 6 to the pipe 71, first, the stopper part side bending guide member 5 and one end of the release wire 4 are attached to the case member 61, and then the claw part 61K is inserted into the wide part 71F. To do. Next, the case member 61 is rotated relative to the pipe 71 until the convex portion 61N is locked in the recess portion 71I, and the base portion 61L is disposed in the narrow portion 71G and is locked to the locked portion 71H. The part 61M is locked. Thereby, the stopper cover drive mechanism 6 is attached to the pipe 71. The protrusion 61N is locked to the recess 71I, so that the relative rotation of the case member 61 with respect to the pipe 71 is restricted, and as a result, the stopper cover driving mechanism 6 can be more reliably prevented from falling off the pipe 71. It has become.

  Furthermore, as shown in FIG. 7, the front side contact part 61P and the back side contact part 61Q which oppose each other are provided in the inside of the first component part 61A.

  The movement direction conversion part 62 includes a rack part 62A and a gear part 62B.

  One end portion of the transmission member 41 is connected to the rack portion 62A, and is disposed between the front contact portion 61P and the rear contact portion 61Q in a state adjacent to the standing wall portion 61E. Further, the side surface of the rack portion 62A on the standing wall portion 61E side has a flat shape. During the reciprocating motion of the transmission member 41, the rack portion 62A reciprocates while its flat side surface slides with respect to the standing wall portion 61E. Further, a plurality of teeth formed along the reciprocating direction of the rack portion 62A are formed on the side surface of the rack portion 62A that is located behind the flat side surface.

  Further, in the present embodiment, when the rack portion 62A moves forward with the forward movement of the transmission member 41, the rack portion 62A comes into contact with the front contact portion 61P, so that further forward movement of the rack portion 62A is restricted. It has come to be. On the other hand, when the rack portion 62A is moved backward along with the backward movement of the transmission member 41, the rack portion 62A comes into contact with the rear side contact portion 61Q so that further backward movement of the rack portion 62A is regulated. It has become.

  The gear portion 62B is provided integrally and coaxially with the rotating shaft 63, and meshes with the teeth formed on the rack portion 62A. Therefore, the gear part 62B rotates with the reciprocating motion of the rack part 62A.

  The rotation shaft 63 is exposed to the outside from the case member 61 (see FIG. 6 and the like), and is configured to rotate together with the gear portion 62B. Further, as shown in FIG. 4, the rotation shaft 63 is located between the disc portion 63A exposed to the internal space of the pipe main body portion 71A, the gear portion 62B, and the disc portion 63A, and is more than the disc portion 63A. A small-diameter portion 63B having a small diameter.

  The disc part 63A includes a columnar support protrusion 66 that protrudes into the pipe body 71A on the outer peripheral side of the end face on the pipe body 71A side. The support protrusion 66 moves up and down as the gear portion 62B and thus the rotation shaft 63 rotates. The support protrusion 66 supports the outer peripheral wall portion 72A, and the protrusion amount of the support protrusion 66 with respect to the inner peripheral surface of the pipe 71 (pipe main body 71A) is sufficient. Therefore, the protrusion amount of the support protrusion 66 with respect to the inner peripheral surface of the pipe 71 (the pipe body 71A) is set to be very small (for example, 5 mm or less).

  In addition, in the present embodiment, as described above, the reciprocating range of the rack portion 62A is defined by the front contact portion 61P and the rear contact portion 61Q. The possible range is specified. That is, in the present embodiment, the rotation range defining means is configured by the front contact portion 61P and the rear contact portion 61Q. Then, by defining the pivotable range of the pivot shaft 63, the movable range along the vertical direction of the support protrusion 66, that is, the stroke amount (vertical movement amount) of the plug lid 75 is defined. It has become.

  The holding member 64 has a cylindrical shape having an outer diameter substantially the same as that of the disk portion 63A, and is disposed on the outer periphery of the small diameter portion 63B. Further, in a state where the stopper cover driving mechanism 6 is attached to the pipe 71, the holding member 64 is sealed by a predetermined ring member 67 so that the outer peripheral surface thereof is watertightly sealed against the inner peripheral surface of the mounting cylinder portion 71B. It has become.

  The sealing member 65 is formed of an elastically deformable material (for example, rubber or the like), and is in watertight contact with the inner peripheral surface of the holding member 64 and the outer peripheral surface of the small diameter portion 63B. The sealing member 65 prevents water leakage that has traveled along the outer peripheral surface of the rotating shaft 63.

  As described above in detail, according to the present embodiment, the release wire 4 is attached to the stopper cover driving mechanism 6, and then the stopper cover driving mechanism 6 is connected from the outside of the pipe 71 to the pipe 71 (attachment cylinder portion 71 </ b> B). Can be easily installed to. Therefore, the work related to the attachment and replacement of the stopper lid driving mechanism 6 can be made extremely easy, and the attachment workability and the maintenance ability can be greatly improved. Further, it is not necessary to pull out the stopper cover driving mechanism or the transmission member from the inside of the pipe at the time of mounting work, and the work can be performed while confirming the state of the release wire 4. Therefore, it is possible to more reliably prevent the members such as the release wire 4 from being damaged.

  In addition, in the present embodiment, the protruding amount of the support protrusion 66 with respect to the inner peripheral surface of the pipe 71 (pipe body 71A) is very small. Therefore, it is difficult for dust and the like to adhere to the support protrusion 66, and the clogging of the pipe 71 can be effectively suppressed. In addition, the pipe 71, the trap, and the like that are located behind (below) the support protrusion 66 can be cleaned relatively easily, and the cleanability can be improved.

  Further, when the stopper cover driving mechanism 6 is attached to the pipe 71, the sealing member 65 provided in the stopper cover driving mechanism 6 makes the space between the rotation shaft 63 and the holding member 64 positioned around the shaft 63 watertight. Retained. Therefore, it is not necessary to perform a separate operation in order to ensure watertightness during the mounting operation, and the mounting workability and maintainability can be further improved.

  In addition, the sealing member 65 is provided on the outer periphery of the small diameter portion 63 </ b> B on the rotation shaft 63. Therefore, the sealing member 65 can be made to have a relatively small diameter. As a result, the area of the rotating shaft 63 (small diameter portion 63B) and the contact portion between the holding member 64 and the sealing member 65 and the diameter of the contact portion are relatively set. Can be small. Thereby, the resistance at the time of rotating the rotating shaft 63 can be reduced, and the rotating shaft 63 can be smoothly rotated even if the force applied to the displacement member 23 is relatively small. As a result, operability and operational stability can be improved.

  Further, according to the present embodiment, the distance along the radial direction from the rotation center of the disc portion 63A to the support protrusion 66 can be made sufficiently large. Therefore, the amount of movement of the support protrusion 66 along the vertical direction when the rotation shaft 63 is rotated, and thus the stroke amount of the plug lid 75 can be sufficiently increased. As a result, it is possible to ensure good drainage capacity when the drain port 104 is opened.

  Furthermore, in this embodiment, the front-side contact portion 61P and the rear-side contact portion 61Q constituting the rotation range defining means are provided in the plug lid driving mechanism 6, and the rotation shaft 63 is not interposed via the transmission member 41. The pivotable range is defined. Therefore, the rotatable range of the rotation shaft 63 can be defined more accurately and with high accuracy. As a result, the stroke amount of the plug lid 75 can be accurately set to the target.

  In addition, the movement direction conversion part 62 has a relatively simple configuration including a rack part 62A and a gear part 62B engaged with the rack part 62A. Therefore, it is possible to suppress an increase in manufacturing cost, and it is possible to reduce the size of the stopper cover driving mechanism 6.

  In the state where the stopper lid 75 and the support shaft 73 are pulled up from the front side of the basin 100 and the water passage member 72, the support shaft 73, the hair catcher 74 and the stopper lid 75 are removed from the pipe 71, the pipe 71 (pipe body) Only the support protrusion 66 protrudes from the inner peripheral surface of the portion 71A). Therefore, in combination with the small protrusion amount of the support protrusion 66 with respect to the inner peripheral surface of the pipe 71 (pipe main body 71A), the cleanability can be further improved.

It is set to be larger than the minimum amount necessary for rotating the rotation shaft 63 so as to move from one of the positions (arrangement position when the drain port 104 is opened) to the other of the two. This is particularly effective when In this case, when the displacement member 23 is displaced, the support protrusion 66 can be more reliably disposed with respect to the upper limit position and the lower limit position, while the displacement member 23 is displaced and the transmission member 41 is reciprocated. When this is done, an overload is easily applied to the transmission member 41.
