Description

  The present invention relates to an operating device for remotely operating a plug lid provided at a drain outlet of a bathtub.

  2. Description of the Related Art Conventionally, an operation device that opens and closes a drainage port of a bathtub by moving a stopper lid up and down by remote control is known.

  As such an operating device, it is inserted between the overflow port formed through the side wall of the bathtub, and can be reciprocated along the direction in which the overflow port extends, and is provided between the operating member and the lid. Some have a transmission member inserted in a reciprocable manner with respect to the inner periphery of a tubular tube member. In this type of operating device, the operating member is pressed, and the transmitting member moves on the inner periphery of the tube member, whereby the stopper lid is moved up and down. Further, the operation member and one end portion of the transmission member located on the operation member side are in a state of being arranged in series, and the reciprocation direction of the operation member is the same as the reciprocation direction of the one end portion of the transmission member. The direction is generally known (see, for example, Patent Document 1).

JP 2011-174346 A

  By the way, when the positional relationship and the operation direction between the operation member and one end of the transmission member are set as described above, the length of the operation device along the reciprocation direction of the operation member becomes relatively large. End up. Therefore, from the viewpoint of safety and aesthetics, if the operation member is configured not to protrude from the surface of the bathtub to the near side (water storage space side of the bathtub), the operation device will protrude greatly from the back of the bathtub to the back side. Become. On the other hand, the side wall of the bathtub usually tends to have a small distance from the wall surface or apron located on the back side. Therefore, it is difficult to dispose the operating device corresponding to the overflow port formed in the side wall.

  If the operation member is configured to protrude from the surface of the bathtub toward the front side, it is relatively easy to dispose the operation device corresponding to the overflow port. There is a risk of lowering.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an operating device that can be easily disposed corresponding to an overflow port while ensuring good safety and aesthetics. There is.

  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.

Means 1. An operation member that is inserted into the overflow port formed through the side wall of the bathtub and is capable of reciprocating along the direction in which the overflow port extends,
A tubular tube member, and a release wire configured to be reciprocally movable on the inner periphery of the tube member, and having a transmission member that transmits the displacement of the operation member to the side of the stopper lid provided at the drain outlet of the bathtub; With
The operating member is
An operated portion to be exposed on the surface side of the bathtub;
An operating device having a shaft portion fixed directly or indirectly to the operated portion and extending along a reciprocating direction of the operating member;
A rotation restricting portion for restricting the shaft portion from being relatively unrotatable with respect to the bathtub;
It is arranged on the outer periphery or inner periphery of the shaft portion, and is rotatable relative to the shaft portion along the circumferential direction of the shaft portion. A cylindrical rotating part that presses and moves one end of the transmission member forward along a tangential direction of its rotating direction;
The rotation part has a rotation side contact part that can come into contact with a shaft side contact part provided in the shaft part,
At least one of a portion of the shaft-side contact portion that contacts the rotation-side contact portion and a portion of the rotation-side contact portion that contacts the shaft-side contact portion is in a reciprocating direction of the operation member. An inclined surface that inclines against
With the forward movement of the operation member due to the pressing of the operated portion, the shaft-side contact portion presses the rotation-side contact portion so that the rotation portion rotates relative to the shaft portion. An operating device that is configured.

  According to the means 1, when the operating member is moved forward, the rotating portion rotates and presses one end of the transmission member, and as a result, along the tangential direction of the rotating direction of the rotating portion. One end of the transmission member moves forward. Therefore, the reciprocating direction of the one end portion of the transmission member can be a direction (circumferential direction of the operating member) orthogonal to the reciprocating direction of the operating member, and the operating member and one end portion of the transmitting member are in series. It is possible not to line up. Thereby, the length of the operating device along the reciprocating direction of the operating member can be made very small. As a result, it is possible to more easily dispose the operating device corresponding to the overflow port of the side wall portion having a small distance from the wall surface or the like while ensuring good safety and aesthetics.

  Further, the rotation restricting portion can make the shaft portion relatively unrotatable with respect to the bathtub, and as a result, the rotating portion can be more reliably rotated when the operation member is moved forward. Thereby, the above-mentioned effect can be more reliably exhibited.

  Furthermore, in order to make the reciprocating direction of the transmission member perpendicular to the reciprocating direction of the operating member (circumferential direction of the operating member), it is necessary to bend the release wire as shown in FIG. There is no. Accordingly, it is possible to more reliably prevent the frictional force generated between the transmission member and the tube member from increasing due to the bending of the release wire, resulting in a decrease in operability or damage to the transmission member. .

  Mean 2. 2. The operation according to claim 1, wherein when the surface of the operated portion is pressed, the movement amount of one end portion of the transmission member is configured to be larger than the movement amount of the operation member. apparatus.

  According to the above means 2, the amount of reciprocation (stroke amount) of the operating member can be made smaller while achieving more reliable vertical movement of the stopper lid. Accordingly, the length of the operating device along the reciprocating direction of the operating member can be made smaller, and it becomes easier to dispose the operating device corresponding to the overflow port.

  Furthermore, since the amount of movement of the operation member necessary to open and close the drain port can be reduced, when the user tries to open and close the drain port, the amount of movement of the operation member becomes insufficient. It is possible to more reliably prevent a situation in which the opening / closing fails (for example, the drain outlet is intended to be closed but is not actually closed). Thereby, the usability for the user can be improved.

  For example, the means 2 adjusts the distance (turning radius) from the turning shaft of the turning portion to the portion of the turning portion that presses one end of the transmission member, or adjusts the shaft-side contact portion and the turning portion. The inclination angle of the inclined surface portion provided on at least one of the moving side contact portions is adjusted with respect to the reciprocating direction of the operation member [that is, the rotation amount (rotation angle of the rotation portion per unit movement amount of the operation member) ) And adjust].

Means 3. At least a portion of the rotating side contact portion that contacts the shaft side contact portion has an inclined surface shape that is inclined with respect to the reciprocating direction of the operation member,
A portion of the rotating contact portion that contacts the shaft contact portion has a spiral shape in which the inclination of the operation member with respect to the reciprocating direction is constant over the entire area. The operating device according to 1.

  According to the above means 3, when the operating member is moved forward, the portion in contact with the rotation side contact portion in the shaft side contact portion can always be the same portion. Therefore, when the operating member is moved forward, the rotating portion can be stably rotated, and the operational stability can be improved.

  Further, according to the means 3, when the operation member is moved forward, the user can change the load generated in the operation member (the load is, for example, a return force applying unit for moving the transmission member backward). It is possible to more reliably perceive a change in the generated force, a change in frictional force generated between the shaft-side contact portion and the rotation-side contact portion, a change in the state of opening, and the like. As a result, when the user opens and closes the drain port, the user can more surely grasp the status of the operation member and the plug lid through the operation member, and moreover, an operation error occurs. It can be surely prevented.

Means 4. At least a portion of the rotating side contact portion that contacts the shaft side contact portion has an inclined surface shape that is inclined with respect to the reciprocating direction of the operation member,
3. The operating device according to claim 1, wherein a portion of the rotating side contact portion that contacts the shaft side contact portion has a shape in which an inclination of the operation member with respect to a reciprocating movement direction is not constant.

  According to the above means 4, it is possible to obtain good operability by adjusting the inclination of the rotation side contact portion in consideration of the force applied to the operation member when the operation member is moved forward.

  For example, when the operating member is moved forward to rotate the rotating part, it takes into consideration that a relatively large force is required until the rotating part starts rotating and starts opening. Then, of the rotation side contact portion, when the operation member is moved forward to rotate the rotation portion, the inclination of the portion that first contacts the shaft side contact portion is changed to the other portion of the rotation side contact portion. You may make it gentler than an inclination. In this case, it is possible to relatively reduce the pressing force to the operated portion that is required when the turning portion is turned to start opening the plug.

  Further, for example, a return force applying portion (spring member) for moving the transmission member backward is provided, and as the operation member moves forward, the return force applying portion or the like applies to the operation member in the return direction. When the force is configured to be large, the shaft side contact at the stage where the force applied in the backward movement direction from the return force applying portion or the like to the operation member among the rotation side contact portions becomes larger than a predetermined value. The inclination of the part that contacts the part may be made gentler than the inclination of the other part in the rotation side contact part. In this case, for example, in the final stage when the operated portion is moved forward, the pressing force required to be applied to the operated portion in order to rotate the rotating portion can be kept relatively small. it can.

  Further, for example, of the rotating side contact portion, a stage where the pressing force that needs to be applied to the operated portion to rotate the rotating portion can be relatively small (for example, rotation start of the rotating portion) The slope of the portion that comes into contact with the shaft-side contact portion at a later stage until there is no play or gap between the members may be made relatively steep. In this case, the transmission member can be moved relatively large even if the pushed amount (operation amount) of the operated portion is relatively small.

Means 5. At least a portion of the shaft-side contact portion that contacts the rotation-side contact portion has an inclined surface shape that is inclined with respect to the reciprocating direction of the operation member,
A portion of the shaft-side contact portion that contacts the rotation-side contact portion has a spiral shape in which the inclination of the operation member with respect to the reciprocating movement direction is constant throughout the entire region. The operating device according to 1.

  According to the means 5, basically the same effect as that of the means 3 is obtained. That is, it is possible to improve the operational stability and more reliably prevent a situation such as an operation error from occurring.

Means 6. At least a portion of the shaft-side contact portion that contacts the rotation-side contact portion has an inclined surface shape that is inclined with respect to the reciprocating direction of the operation member,
3. The operating device according to claim 1, wherein a portion of the shaft-side contact portion that contacts the rotation-side contact portion has a shape in which an inclination of the operation member with respect to a reciprocating movement direction is not constant.

  According to the means 6, basically the same effect as that of the means 4 is achieved. That is, it is possible to obtain good operability by adjusting the inclination of the shaft side contact portion in consideration of the force applied to the operation member when the operation member is moved forward.

  As the operation device according to the means 6, for example, the configuration of the rotation side contact portion exemplified in the means 4 is applied to a portion of the shaft side contact portion that contacts the rotation side contact portion. Can be mentioned.

  Mean 7 The operating device according to any one of means 1 to 6, wherein the shaft side contact portion and the rotation side contact portion are point contact or line contact.

  According to the means 7, the contact resistance between the shaft side contact portion and the rotation side contact portion can be made smaller. Therefore, the force required to move the operating member can be further reduced, and the operability can be further improved.

Means 8. It is attached directly or indirectly to the bathtub, and includes a rotation support portion that contacts an end surface of the rotation portion in the rotation axis direction, and that the end surface slides when the rotation portion rotates.
The shaft portion includes a hole opening on the opposite side to the operated portion,

The operation device according to any one of means 1 to 7, wherein the rotation restricting portion is configured by a portion of the shaft portion where the hole portion is formed.

  According to the means 8, the rotating part slides on the rotating support part when rotating. Therefore, the rotation unit can be rotated more stably, and the operational stability of the apparatus can be further enhanced.

  Further, according to the means 8, the rotation support part has a part of the rotation restricting part (bar-shaped part). Therefore, the apparatus can be further reduced in size, and it is possible to more easily dispose the operating device corresponding to the overflow port, and the manufacturing cost can be reduced.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, the drain plug device 1 includes a drain port device 2 and an operation device 3, and is attached to a bathtub 100.

  The bathtub 100 includes a bottom wall portion 101 and a side wall portion 102 erected on the outer periphery of the bottom wall portion 101. Further, a drainage outlet 103 for drainage is formed through the bottom wall portion 101, and an overflow port 104 for preventing overflow of water from the bathtub 100 is formed through the upper portion of the side wall portion 102. ing. Furthermore, in this embodiment, the space between the side wall portion 102 and the structure ST such as a wall or an apron located on the back side thereof is relatively narrow. In other words, the internal space of the portion of the bathtub 100 where the operating device 3 is attached is relatively small.

  First, the configuration of the drain port device 2 will be described. As shown in FIG. 2, the drain port device 2 is provided in the drain port 103 and includes a drain port member 21, a drain pipe 22, a support shaft mechanism 23, and a plug lid 24.

  The drain port member 21 has a cylindrical shape and is inserted into the drain port 103. Further, the drain port member 21 holds the support shaft mechanism 23 inside itself.

  The drain pipe 22 includes a main pipe 22A and a branch pipe 22B. The main pipe 22 </ b> A has a cylindrical shape extending along the vertical direction, and is disposed coaxially with the drain port member 21 below the drain port member 21.

  The branch pipe 22B extends along the direction orthogonal to the direction in which the main pipe 22A extends from the outer periphery of the main pipe 22A. Further, the branch pipe 22B has an internal space communicating with the internal space of the main pipe 22A, and is connected to a pipe 32 (to be described later) of the operating device 3 via a connection pipe (not shown).

  The support shaft mechanism 23 has a support shaft 23A to which the other end portion of a transmission member 33A, which will be described later, can contact, and to which the plug lid 24 is attached at the upper end portion. Further, the support shaft mechanism 23 is provided with a lock mechanism (for example, a thrust lock mechanism) (not shown). The lock mechanism locks the support shaft 23A at a predetermined upper position each time the transmission member 33A moves forward (moves from the operation device 3 to the drain port device 2 side), and supports the lock when the lock is released. The shaft 23 </ b> A is alternately arranged at a position below the upper position.

  Further, the support shaft mechanism 23 includes a return force applying portion (for example, a spring member) (not shown). In a state in which the lock by the lock mechanism is released, the return force applying portion causes the return member 33A to move in the backward direction (from the drain port device 2 to the operation device) except when the drain port 103 is closed. A biasing force (toward the 3rd side) is applied.

  The plug lid 24 includes a disk-shaped plug lid main body 24A and a packing portion 24B provided on the back surface of the plug lid main body 24A. When the stopper lid 24 is moved downward along with the downward movement of the support shaft 23A, the packing portion 24B comes into contact with the inner peripheral surface of the drain port member 21, whereby the drain port 103 is closed. On the other hand, when the stopper lid 24 is moved upward along with the upward movement of the support shaft 23A, the packing portion 24B is separated from the inner peripheral surface of the drain port member 21, so that the drain port 103 is opened.

  Next, the configuration of the controller device 3 will be described. As shown in FIG. 1, the operation device 3 includes an attachment member 31, a pipe 32, a release wire 33, and an operation side mechanism unit 34.

  The attachment member 31 has a cylindrical shape and is inserted through the overflow port 104. The attachment member 31 includes a flange portion 31A that protrudes radially outward at one end portion thereof, and a male screw portion 31B that is formed on the outer peripheral surface on the other end side of the flange portion 31A. Furthermore, the attachment member 31 includes a plurality of attachment projections 31C (see FIG. 3) provided at equal intervals along the circumferential direction on the inner periphery of the other end.

  The pipe 32 has a cylindrical shape that bends at a substantially right angle, and includes an internal thread portion 32A that can be screwed with the external thread portion 31B on the inner periphery of one end thereof (on the overflow port 104 side). In the present embodiment, the pipe 32 is arranged coaxially with the overflow port 104 on the back side of the side wall 102, and the male screw portion 31 </ b> B of the mounting member 31 is screwed to the female screw portion 32 </ b> A through the overflow port 104. In addition, by sandwiching the side wall portion 102 by one end face of the pipe 32, the pipe 32 is connected to the attachment member 31 and is attached to the side wall portion 102. In the present embodiment, an annular seal member 5 formed of an elastically deformable material is disposed between the back surface of the side wall portion 102 and one end surface of the pipe 32, and is attached by the seal member 5. The leakage of water from between the member 31 and the pipe 32 and the bathtub 100 is prevented.

  Further, a slit portion 32B extending in a direction parallel to the axial direction of the inner cylindrical portion 341B described later is formed in a portion of the pipe 32 arranged at the upper portion on the other end side of the operation side mechanism portion 34.

  In addition, a connecting pipe (not shown) connected to the drain pipe 22 is connected to the other end (lower end) of the pipe 32. Thereby, the waste water that has flowed into the pipe 32 through the inside of the attachment member 31 flows through the connecting pipe and into the drain pipe 22.

  The release wire 33 is provided between the support shaft mechanism 23 and the operation side mechanism section 34, and includes a long transmission member 33A made of a wire or the like and a long cylindrical tube member 33B made of a resin or the like. ing. 33 A of transmission members are arrange | positioned at the inner periphery of the tube member 33B, and can be reciprocated with respect to the tube member 33B.

  The holding member 341 is made of resin, and is a member for holding the rotating portion 342, the operation member 344, and the like inside the pipe 32. As shown in FIGS. 3 to 5, the holding member 341 includes an outer annular portion 341A, an inner cylindrical portion 341B, and an arm portion 341C.

  The outer annular portion 341 </ b> A has an annular shape whose outer diameter is substantially the same as the inner diameter of the mounting member 31. The outer annular portion 341A includes a claw portion 341D (see FIGS. 4 and 5) protruding from the other end face in a direction parallel to the axial direction. A plurality of claw portions 341D are provided at equal intervals along the circumferential direction of the outer annular portion 341A (three in the present embodiment), and the front end portion of each claw portion 341D is an engagement projecting to the outer peripheral side. A portion 341E is formed. Since the holding member 341 is made of resin as described above, the tip of the claw portion 341D can be elastically deformed along the radial direction of the outer annular portion 341A. In this embodiment, the holding member 341 is attached to the attachment member 31 by sandwiching the attachment protrusion 31C of the attachment member 31 by the other end surfaces of the engagement portion 341E and the outer annular portion 341A.

  The inner cylindrical portion 341B is located inside the outer annular portion 341A, and has a cylindrical shape in which both one end and the other end are opened. The rotating portion 342 is inserted into the inner periphery of the inner cylinder portion 341B so as to be relatively rotatable. In addition, the inner cylinder portion 341B has an inner diameter of one end side opening smaller than the inner diameter of the other end side opening, and as a result, the rotating part 342 opens the other end side opening with respect to the inner cylinder portion 341B. While being able to be inserted from the inner cylindrical portion 341B, the inner cylindrical portion 341B does not come out of the opening. In addition, a plate-like anti-rotation protrusion 341F protruding outward in the radial direction is formed on the outer periphery of the inner cylindrical portion 341B, and the anti-rotation protrusion 341F is disposed in the slit portion 32B of the pipe 32. Has been. As a result, the holding member 341 is disposed at an appropriate position in the circumferential direction, and rotation of the holding member 341 is prevented.

  The arm portion 341C connects the inner peripheral surface of the outer annular portion 341A and the outer peripheral surface of the inner cylindrical portion 341B, and holds the inner cylindrical portion 341B inside the outer annular portion 341A. A plurality (three in this embodiment) of arm portions 341C are provided at equal intervals along the circumferential direction of the outer annular portion 341A. A gap is formed between adjacent arm portions 341 </ b> C, and the water that has flowed into the internal space of the attachment member 31 flows into the pipe 32 through the gap.

  The rotating part 342 has a cylindrical shape and is arranged on the outer periphery of a shaft part 344B (described later) of the operation member 344 (see FIG. 1). Moreover, the rotation part 342 is rotatable relative to the shaft part 344B along the circumferential direction thereof. Further, a curved recess 342A (see FIG. 5) is formed on the outer peripheral side of the other end surface of the rotating portion 342, and one end portion of the transmission member 33A is fitted into the recess 342A. The moving part 342 and the transmission member 33A are connected. When the rotating unit 342 rotates, the rotating unit 342 presses one end portion of the transmission member 33A along the rotating direction, and as a result, in the tangential direction of the rotating unit 342 in the rotating direction. Along with this, one end of the transmission member 33A moves forward (moves from the operation device 3 to the drain port device 2 side).

  Further, a rotation-side contact portion 342 </ b> B having an inclined surface shape inclined with respect to the circumferential direction of the rotation portion 342 is formed on the inner periphery of the rotation portion 342. The rotation-side contact portion 342B is a portion that can come into contact with a shaft-side contact portion 344D of a shaft portion 344B described later along the rotation axis direction. Further, a portion of the rotation side contact portion 342B that is in contact with the shaft side contact portion 344D is configured to have a spiral shape in which the inclination with respect to the rotation axis direction is constant over the entire area. In the present embodiment, two rotation-side contact portions 342B are provided on the inner periphery of the rotation portion 342.

  The rotation support part 343 is screwed and fixed to the inner cylinder part 341B so as to close the other end side opening of the inner cylinder part 341B and the opening of the concave part 342A. That is, the rotation support part 343 is indirectly attached to the bathtub 100 via the holding member 341 and the attachment member 31.

  The rotation support portion 343 includes a flat plate-like portion 343A that closes the opening on the other end side of the inner cylinder portion 341B, and a rod-like portion 343B that protrudes from the center of the plate-like portion 343A.

  The plate-shaped portion 343A has at least a portion that faces the other end surface of the rotating portion 342 in a smooth and smooth shape. When the rotating portion 342 rotates, the other end surface of the rotating portion 342 with respect to the facing portion. Are configured to slide while in contact with each other.

  The rod-shaped portion 343B has a cylindrical shape and has a plurality of ribs (protrusions) extending along the axial direction on the outer peripheral surface (four in this embodiment). Further, the base portion of the rod-like portion 343B has a columnar shape, and the rotating portion 342 is supported by the base portion.

  As shown in FIG. 1, the operation member 344 is inserted into the overflow port 104 and is provided so as to be capable of reciprocating along the direction in which the overflow port 104 extends. The operating member 344 includes an operated portion 344A that is circular when viewed from the water storage space side of the bathtub 100, and a shaft portion 344B that is fixed to the operated portion 344A in a coaxial state.

  The operated part 344 </ b> A is a part operated by the user when opening and closing the drainage port 103, and is exposed on the surface side of the bathtub 100 (side wall part 102). Further, in the present embodiment, when the drainage port 103 is closed, the surface of the operated portion 344A is configured to be flush with the surface of the flange portion 31A, and the operated portion 344A is always the surface of the mounting member 31. It is supposed not to protrude from. Thereby, the appearance quality and safety are improved.

  The shaft portion 344B extends in the reciprocating direction of the operation member 344 and has a rod shape including a hole portion 344C (see FIG. 5) that opens to the opposite side of the operated portion 344A. The hole portion 344C is formed with a plurality of recess portions having a shape corresponding to the rib of the rod-shaped portion 343B. The rod-shaped portion 343B is inserted into the hole 344C so that the rib of the rod-shaped portion 343B is disposed in the recessed portion of the hole 344C. Accordingly, the shaft portion 344B is not rotatable relative to the rod-shaped portion 343B and thus the bathtub 100. That is, in the present embodiment, a rotation restricting portion that restricts the relative rotation of the shaft portion 344B with respect to the bathtub 100 is configured by the portion where the hole portion 344C is formed in the rod-shaped portion 343B and the shaft portion 344B.

  Furthermore, as shown to FIGS. 3-5, two fan-shaped axial side contact parts 344D which protrude outside are formed in the outer periphery of the axial part 344B. Each of the shaft side contact portions 344D has such a size that it cannot pass through the opening on one end side of the inner cylinder portion 341B, and is always disposed inside the rotation portion 342. Further, when the operation member 344 is moved forward, a surface of the shaft side contact portion 344D that is located on the front side in the forward movement direction of the shaft portion 344B can be brought into surface contact with the rotation side contact portion 342B. .

  In addition, in this embodiment, the operation side mechanism part 34 is comprised from the surface side (water storage space side) of the bathtub 100 so that attachment or detachment with respect to the attachment member 31 is possible. When attaching the operation side mechanism part 34 to the attachment member 31, first, the operation side mechanism part 34 to which the release wire 33 is connected is inserted into the attachment member 31 from the surface side of the bathtub 100 in a predetermined direction. Then, after positioning the holding member 341 so that the rotation preventing projection 341F can be inserted into the slit portion 32B, the tapered portion formed on the outer periphery of the distal end of the engaging portion 341E is attached to the mounting projection. The claw portion 341D is gradually elastically deformed radially inward by pushing the operation side mechanism portion 34 toward the back side of the mounting member 31 while being in contact with 31C. When the claw portion 341D is elastically deformed by a predetermined amount or more, the engaging portion 341E moves beyond the attachment protrusion 31C to the deeper side of the attachment member 31, and the elastic deformation of the claw portion 341D is released. As a result, the attachment protrusion 31C is sandwiched between the other end surface of the outer annular portion 341A and the engagement portion 341E, and the operation side mechanism portion 34 is attached to the attachment member 31. That is, in this embodiment, the operation side mechanism 34 can be attached to the attachment member 31 with one touch.

  On the other hand, when removing the operation side mechanism portion 34 from the attachment member 31, if the operation side mechanism portion 34 is pulled in the direction opposite to that at the time of attachment, the engagement portion 341E is detached from the attachment projection 31C, and the attachment member 31 is removed. The operation side mechanism part 34 can be removed from. In this way, the operation side mechanism 34 can be attached to and detached from the attachment member 31 so that the inner peripheral surface of the attachment member 31 and the pipe 32 can be cleaned, and the parts at the time of failure of the operation side mechanism 34 can be obtained. Replacement work and the like are facilitated, and the cleaning property and the maintenance property are improved.

  Next, the operation of each part when the drainage port 103 is opened and closed will be described. First, when the drainage port 103 is changed from the closed state to the open state, the shaft-side contact portion 344D presses the rotation-side contact portion 342B by pushing the operated portion 344A and moving the operation member 344 forward, and thus rotating. The moving part 342 rotates relative to the shaft part 344B. As a result, one end portion of the transmission member 33A is pressed by the rotating portion 342, and the one end portion of the transmitting member 33A moves forward along the tangential direction of the rotating portion 342 in the rotating direction. This also causes the transmission member 33A to move forward in the tube member 33B, and the support shaft 23A is pushed up by the other end of the transmission member 33A. When the support shaft 23A is pushed up to a predetermined position or more, the support mechanism 23A is locked at a predetermined upper position with the plug lid 24 being separated from the drain port member 21 by the locking mechanism, and the drain port 103 is opened. Is done.

  On the other hand, when the drainage port 103 is changed from the open state to the closed state, the transmission member 33A is moved forward by pressing the operated portion 344A and moving the operation member 344 forward as in the case of opening the drainage port 103. . As a result, the lock of the support shaft 23A by the lock mechanism is released, and the support shaft 23A and the plug lid 24 are moved downward by the action of gravity or the return force applying portion. As a result, the drainage port 103 is closed. Further, the transmission member 33A moves backward in the tube member 33B by the action of the return force applying portion, and the rotating portion 342 opens the drain port 103 when pressed by one end portion of the transmission member 33A. It rotates in the opposite direction. As a result, the shaft side contact portion 344D is pressed by the rotation side contact portion 342B, the shaft portion 344B (operation member 344) moves backward, and the surface of the operated portion 344A is flush with the surface of the flange portion 31A. It will return to the state.

  In the present embodiment, the distance (radius) from the rotation shaft of the rotation unit 342 to the portion of the rotation unit 342 that presses one end of the transmission member 33A is adjusted, or the reciprocating direction of the operation member 344 is adjusted. By adjusting the inclination angle of the rotation-side contact portion 342B with respect to the movement portion 344A, when the operated portion 344A is pressed, the movement amount of the one end portion of the transmission member 33A becomes larger than the movement amount of the operation member 344. It is configured.

  As described above in detail, according to the present embodiment, the reciprocating direction of the one end portion of the transmission member 33A can be set to the direction orthogonal to the reciprocating direction of the operating member 344 (the circumferential direction of the operating member 344). In addition, the operation member 344 and one end of the transmission member 33A can be prevented from being arranged in series. Thereby, the length of the operating device 3 along the reciprocating direction of the operating member 344 can be made very small. As a result, it is possible to more easily dispose the operating device 3 corresponding to the overflow port 104 of the side wall 102 having a small distance from the structure ST while ensuring good safety and aesthetics.

  Further, the rotation restricting portion constituted by the shaft portion 344B and the rod-shaped portion 343B can make the shaft portion 344B relatively unrotatable with respect to the bathtub 100, and as a result, the rotating portion 342 when the operation member 344 is moved forward. Can be rotated more reliably. Thereby, the above-mentioned effect can be more reliably exhibited.

  Furthermore, it is not necessary to bend the release wire 33 so that the reciprocating direction of the transmission member 33A is perpendicular to the reciprocating direction of the operating member 344 (the circumferential direction of the operating member 344). Accordingly, the bending force of the release wire 33 increases the frictional force generated between the transmission member 33A and the tube member 33B, thereby reducing the operability or causing damage to the transmission member 33A. It can be surely prevented.

  Further, in the present embodiment, when the surface of the operated portion 344A is pressed, the movement amount of the one end portion of the transmission member 33A is configured to be larger than the movement amount of the operation member 344. Therefore, the amount of reciprocation (stroke amount) of the operation member 344 can be made smaller while achieving more reliable vertical movement of the plug lid 24. As a result, the length of the operating device 3 along the reciprocating direction of the operating member 344 can be made smaller, and the operating device 3 can be more easily disposed corresponding to the overflow port 104. Become.

  Furthermore, since the amount of movement of the operation member 344 required to open and close the drain port 103 can be reduced, the amount of movement of the operation member 344 becomes insufficient when the user attempts to open and close the drain port 103. Thus, it is possible to more reliably prevent a situation where the opening and closing of the drainage port 103 fails. Thereby, the usability for the user can be improved.

  In addition, since the rotation-side contact portion 342B has a spiral shape with a constant inclination, when the operation member 344 is moved forward, the portion that contacts the rotation-side contact portion 342B in the shaft-side contact portion 344D is always the same. Can be part. Therefore, when the operation member 344 is moved forward, the rotation part 342 can be stably rotated, and the operational stability can be improved.

  Further, when the operation member 344 is moved forward, the user changes the load generated on the operation member 344 (the load is, for example, a change in force generated in the return force applying unit, the shaft-side contact unit 344D, and the rotation). It is possible to more reliably perceive a change in frictional force generated between the moving contact portions 342B, an open / closed state of the drain port 103, and the like. As a result, when the user opens and closes the drainage port 103, the user can more reliably grasp the status of the operation member 344 and the plug lid 24 via the operation member 344, and thus an operation error occurs. Can be prevented more reliably.

  In addition, since the rotation part 342 slides on the rotation support part 343 at the time of rotation, the rotation part 342 can be more stably rotated, and the operation stability of the apparatus is further enhanced. Can do.

  Moreover, the rotation support part 343 shall have a part (rod-shaped part 343B) of a rotation control part. Therefore, the device can be further reduced in size, and the operation device 3 can be more easily disposed corresponding to the overflow port 104, and the manufacturing cost can be reduced.

  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) A roller portion that is rotatable with respect to the shaft-side contact portion 344D is provided, and the roller portion presses the rotation-side contact portion 342B as the operation member 344 moves forward by pressing the surface of the operated portion 344A. You may comprise so that it may rotate. In this case, when the rotation part 342 is rotated, the rotation side contact part 342B can be moved very smoothly with respect to the axis side contact part 344D (roller part). Resistance generated between the side contact portion 342B and the side contact portion 342B can be effectively reduced. Therefore, the force required to move the operating member 344 can be further reduced, and better operability can be realized.

  (B) In the above embodiment, the rotation-side contact portion 342B is configured to have a spiral shape with a constant inclination with respect to the reciprocating movement direction of the operation member 344 (the direction in which the rotation axis of the rotation portion 342 extends). However, the inclination of the rotation-side contact portion 342B with respect to the reciprocating direction of the operation member 344 is not necessarily constant. Therefore, for example, as shown in FIG. 6, when the rotation side contact portion 352B of the rotation portion 352 presses the surface of the operated portion 344A in order to open the drainage port 103, the shaft side contact portion 344D. Rotation side contact start end portion 352C that is the first contact portion and the portion that finally contacts shaft side contact portion 344D when the surface of operated portion 344A is pressed to open drainage port 103. A rotation side contact end portion 352D, a rotation side contact start end portion 352C, and a rotation side contact end portion 352E positioned between the rotation side contact end portion 352D, and a rotation side contact start end portion 352C. May be configured to be gentler than that of the rotation-side contact intermediate portion 352E.

  With this configuration, when the rotation unit 352 starts to rotate, a relatively large force is usually required until the rotation unit 352 rotates and begins to open the plug. The pressing force on the operated portion 344A required for the operation can be made relatively small. As a result, good operability can be obtained.

  Note that “the inclination of the rotation-side contact start end portion 352C is gentler than the inclination of the rotation-side contact intermediate portion 352E” means that the rotation portion when the rotation-side contact portion 352B is developed on a plane. The acute angle among the angles formed by the rotation shaft 352 and the rotation side contact start end portion 352C is smaller than the acute angle among the angles formed by the rotation shaft and the rotation side contact intermediate portion 352E. Say. Further, when the rotation-side contact intermediate portion 352E has a curved shape or has a plurality of inclined surfaces with different angles, when the rotation-side contact intermediate portion 352E is developed on a plane, In each part of the rotation side contact intermediate part 352E, the rotation axis and the rotation side contact intermediate part 352E (when the rotation side contact intermediate part 352E is curved, a tangent line that contacts the rotation side contact intermediate part 352E) The acute angle among the angles formed by the rotation angle is larger than the acute angle among the angles formed by the rotation shaft and the rotation side contact start end portion 352C.

  Further, as shown in FIG. 7, the force applied in the backward movement direction from the return force applying portion to the operation member 344 via the transmission member 33 </ b> A in the rotation side contact portion 362 </ b> B of the rotation portion 362 is a predetermined value. The inclination of the portion 362C that comes into contact with the shaft side contact portion 344D at a larger stage may be made gentler than the inclination of the other portion 362D in the rotation side contact portion. In this case, for example, in the final stage when the operated portion 344A is moved forward, the pressing force necessary to be applied to the operated portion 344A to rotate the rotating portion 362 is relatively small. Therefore, the operability can be further improved.

  Further, for example, among the rotation side contact portions, a stage where the pressing force necessary to be applied to the operated portion 344A to rotate the rotation portion 342 may be relatively small (for example, the rotation portion 342). About the part which contacts shaft side contact part 344D in the stage until the play and clearance gap between each member disappear after rotation start, it is good also considering the inclination as comparatively steep. In this case, even if the pushing amount (operation amount) of the operated portion 344A is relatively small, the transmission member 33A can be moved relatively large.

  (C) In the above embodiment, the rotation-side contact portion 342B is configured to have an inclined surface shape, but as shown in FIG. 8, the shaft-side contact portion 374D of the shaft portion 374B has an inclined surface shape. The rotation side contact portion 372B of the rotation portion 372 may be configured to have a non-inclined surface shape (for example, a protrusion shape). Moreover, you may comprise so that both a rotation side contact part and an axial side contact part may make an inclined surface shape.

  In addition, when the shaft-side contact portion has an inclined surface shape, the shaft-side contact portion has a spiral shape with a constant inclination with respect to the reciprocating movement direction of the operation member 344 (the direction in which the rotation shaft of the rotation portion 372 extends). It is good. In this case, as in the above-described embodiment, operational effects such as improved operational stability and prevention of operational errors are exhibited.

  Further, the inclination of the shaft-side contact portion with respect to the reciprocating direction of the operation member 344 is not constant, and for example, the configuration of the rotation-side contact portion shown in (b) above may be applied to the shaft-side contact portion. . In this case, the same effect as the effect described in the above (b) is exhibited.

  Further, when the shaft-side contact portion has an inclined surface, a roller portion that is rotatable with respect to the rotation-side contact portion is provided, and the operation member 344 is moved forward by pressing the surface of the operated portion 344A. You may comprise so that a roller part may rotate, pressing the shaft side contact part. In this case, when the operation member 344 is moved forward, the rotation-side contact portion (roller portion) can be moved very smoothly with respect to the shaft-side contact portion. Resistance generated between the contact portion and the contact portion can be effectively reduced. As a result, the force required to move the operation member 344 can be further reduced, and better operability can be realized.

  (D) In the above embodiment, two shaft-side contact portions 344D and two rotation-side contact portions 342B are provided, but the number of shaft-side contact portions and rotation-side contact portions is not limited to this. Absent. For example, one shaft side contact portion and one rotation side contact portion may be provided, or three or more of each may be provided.

  (E) In the above-described embodiment, the shaft side contact portion 344D and the rotation side contact portion 342B are configured to be in surface contact, but may be configured to be in line contact or point contact. In this case, the contact resistance between the shaft side contact portion and the rotation side contact portion can be made smaller. Therefore, the force required to move the operation member 344 can be further reduced, and the operability can be further improved.

  In order to make point contact between the shaft side contact portion and the rotation side contact portion, for example, one of the rotation side contact portion and the shaft side contact portion is formed in a spiral shape, and the rotation side contact portion and the shaft side A portion of the contact portion facing the one side may be formed in a spherical shape convex on the one side or a pointed shape protruding on the one side.

  (F) In the above embodiment, the rotation-side contact portion 342B having an inclined surface is formed by providing a step on the inner periphery of the rotation portion 342. However, a groove is provided on the inner periphery of the rotation portion 342. It is good also as comprising a rotation side contact part. The same applies to the case where the shaft-side contact portion is inclined.

  (G) In the above-described embodiment, the rotating portion 342 is provided on the outer periphery of the shaft portion 344B. However, the rotating portion may be provided on the inner periphery of the shaft portion. And at least one of the shaft side contact part provided in the inner periphery of the shaft part and the rotation side contact part provided in the outer periphery of the rotation part is formed into an inclined surface shape, so that the operation member moves forward. The rotating part may be configured to rotate with respect to the shaft part.
