Description

  The present invention relates to a remote-operated drain plug device, and more particularly to a remote-operated drain plug device that improves the cleanability of the inside of a pipe and the like.

Conventionally, in order to treat drainage generated inside a tank body such as a bathtub or wash bowl, a drain outlet is provided on the bottom surface of the tank body, and the drainage is discharged from this drain outlet to the sewage side via a drain pipe. Is widely known. In addition, when water is accumulated in the tank body, there is a method of opening and closing the drainage port using a valve member, but the drainage port opening and closing by the valve member is positioned away from the valve member and the drainage port, for example, the tank body There is known a remote-operated drain plug device that is operated by operating an operation section provided above the edge of the tank or the side of the tank body.
As a widely known remote-operated drain plug device, it is constructed in a wash bowl as a tank body as described in Patent Document 1, and the drain port body, joint pipe, operation described below It consists of a release wire as a transmission member, a valve member, and an operation unit.
The wash bowl is a box that is open at the top, and includes a mounting hole for mounting the drainage outlet body on the bottom surface, and an operation section mounting hole for mounting the operation section on the periphery of the upper opening.
The drain port main body is formed in a substantially cylindrical shape to form a drainage channel through which drainage passes, and the opening at the upper end of the channel is a drainage port through which drainage in the tank flows.
The joint pipe is a pipe connected to the lower end of the drain outlet body, bent at the middle part, and placed on the bottom part that hits the position directly below the drain outlet generated by this bending so that the elevating member can be moved forward and backward And it is set as the mechanism part which raises / lowers a valve member.
The release wire includes a cylindrical outer tube and an inner wire that slides forward and backward in the outer tube, and one end is connected to the operation unit and the other end is connected to the mechanism unit.
The operation unit includes an operation body that is directly pushed and pulled by a user, and an operation body that houses the operation body so as to freely advance and retract.
A valve member is comprised from the valve body which closes a waste-water port, and the valve axis | shaft provided in the downward direction from the center of the lower surface of this valve body.
The remote-operated drain plug device configured as described above is applied to the wash bowl as follows.
The upper end of the drain port body is connected to the mounting hole provided in the bottom surface of the wash bowl, and the joint pipe is connected to the lower end of the drain port body (there is no suggestion in Patent Document 1, but the lower end of the joint pipe is further It is connected to the underfloor pipe connected to the sewage side through a pipe pipe).
In addition, the operation unit body is mounted and fixed in the operation unit mounting hole of the wash bowl, and the operation unit side end of the inner wire is used as the operation unit while the operation unit is housed in the operation unit body. The end is connected and fixed to the operation unit main body.
Further, the end portion on the mechanism portion side of the inner wire is connected and fixed to the elevating member, and the end portion on the mechanism portion side of the outer tube is connected and fixed to the joint pipe.
Furthermore, the valve member is arranged from the drain port to the drain port body, and the construction of the remote-operated drain plug device described in Patent Document 1 is completed.
In the remote-operated drain plug device configured as described above, an operation is performed on the operation unit so that the valve member is lowered and the valve body covers and closes the drain port. At this time, the operating body is raised upward. When a push operation is performed on the operating body from this state, the operation applied to the operating body is transmitted to the elevating member via the inner wire, and the elevating member rises to push up the valve shaft. The valve body is separated from the drainage opening. When there is drainage or water discharge in the tank, the drainage flows from the drainage port through the inside of the drainage port main body, the joint pipe, etc., and finally the drainage is discharged from the underfloor piping to the sewage side.
From this state, when the pulling operation is performed on the operating portion, the operation applied to the operating body is transmitted to the lifting member via the inner wire, and the lifting of the lifting member causes the valve shaft support to be lost. Drops, the drainage port is covered again by the valve, and the drainage port is closed.
Thereafter, by performing the same operation, the drain port can be opened / closed by remote operation at the operation unit located away from the drain port.

As a problem of the remote-operated drain plug device described in Patent Document 1 as described above, it is necessary to arrange a mechanism for raising and lowering the valve member of the remote-operated drain plug device inside the drain outlet body and the joint pipe. There is a point that the mechanism part protruding inside the drain pipe is an obstacle to cleaning.
In the case of the remote-operated drain plug device described in Patent Document 1, in order to push up the valve member, it is necessary to push up the valve shaft arranged at the center of the valve member. For this reason, the valve shaft arranged at the center of the drain pipe An elevating member as a mechanism for pushing up and a mechanism for the guide must also be arranged at the center of the drain pipe. However, when the mechanism part as a protruding part is arranged in the central part of the drainage pipe in this way, the distance between the mechanism part and the inner surface of the drainage pipe becomes narrow, and hair or dust in the drainage adheres and accumulates. In addition to being easy to handle, it is difficult to insert and press a cleaning device such as a brush because of its narrowness, resulting in a drainage pipe that becomes dirty and difficult to clean.

As a remote-operated drain plug device that solves the problem of cleanability as described above, a remote-operated drain plug device described in Patent Document 2 has been proposed.
In the remote-operated drain plug device described in Patent Document 2, the valve member is provided with a water passage member formed with a ring-shaped portion, and as a mechanism portion, the water passage member is placed at the center of the drain pipe. The protrusion which does not reach is provided in the side part of the drain pipe.
In the first embodiment (the embodiment shown in FIGS. 1 to 5 in Patent Document 2), on the inner surface of the drain pipe, a movable member having a horizontal axis toward the center of the drain pipe as a rotation axis, and rotation of the movable member A protrusion is arranged in the vicinity of the circumference of the shaft, and the protrusion moves up and down as the movable member rotates, pushes up the water passage member, moves the valve member up and down, and opens and closes the drain port.
In the second embodiment (the embodiment of FIG. 6 in Patent Document 2), the movable member provided with the inclined portion is pushed forward and backward in the central direction of the drain pipe, but to a position not reaching the center. The valve member is moved up and down to open and close the drain port.
In the third embodiment (the embodiment of FIG. 7 in Patent Document 2), on the inner surface of the drainage pipe, a movable member having a rotation axis that is a horizontal axis in the tangential direction of the peripheral edge of the drainage pipe, and an outer peripheral portion of the movable member In this configuration, the protrusion is arranged in the vertical direction so that the protrusion moves up and down as the movable member rotates, pushes up the water passage member, moves up and down the valve member, and opens and closes the drain port.
By configuring as described above, there is no need to provide a protrusion at the center of the drain pipe of the remote-operated drain plug device, and the problem of cleanability that was in the remote-operated drain plug device of Patent Document 1 is eliminated. We were able to.
JP-A-7-224451 JP 2012-36558 A

However, the remote-operated drain plug device configured as described above has the following problems.
In the remote-operated drain plug device described in Patent Document 2, there is a problem in the strength of the protrusion that pushes up the valve member. This will be specifically described below.
Normally, the valve member needs to rise about 10 millimeters when opened. Actually, in the mechanism that pushes up the valve member, when the drain port is closed, the valve member 2 of the valve member 2 In order to provide a clearance of about millimeters, in order to raise the valve member by about 10 millimeters at the time of opening, it is necessary to make the displacement of the height difference of the protrusion from the time of opening of the drain port to the time of closing about 12 millimeters.
In the case of the first embodiment of Patent Document 2, the size (diameter) of the protrusion is 4 millimeters with the assumption that “the displacement of the height difference of the protrusion is 12 millimeters”. Therefore, it is not strong and may be easily damaged when a strong load is applied. In order to ensure strength, it is necessary to enlarge the protrusion, but if the protrusion is enlarged, the entire movable member also needs to be enlarged, which increases the area of the contact portion and increases friction, making it difficult to operate. Thus, a problem arises in that a larger space for rotation is required and the member layout is restricted.
In the case of the third embodiment of Patent Document 2, as in the first embodiment, when the protrusion is thickened to increase the strength of the protrusion, the space for the protrusion to move up and down is reduced accordingly. Therefore, since the angle of rotation of the movable member becomes small and the height difference of the displacement of the protrusion in the vertical direction becomes difficult to be 12 millimeters, the thickness of the protrusion must be thin and the strength should be weak. Must not. If the protrusion length of the protrusion in the central direction of the drain pipe is increased, the height difference in the vertical movement of the tip of the protrusion is set to about 12 millimeters even when the rotation angle is reduced by increasing the thickness of the protrusion. Although it is possible, the protrusion length to the inner side of the drainage pipe is inevitably increased, and even if the tip of the projection does not reach the center of the drainage pipe, the cleaning performance is deteriorated.
In the case of the second embodiment of Patent Document 2, unlike the first embodiment and the third embodiment, the strength of the protrusion can be ensured by preparing a protrusion having a corresponding thickness. . However, in the case of this second embodiment, the protrusion is structured to advance and retract toward the center of the drain pipe. As described above, since “the displacement of the height difference of the operation of the protrusion is about 12 millimeters”, the inclined portion needs to have a height width of 12 millimeters or more in the vertical direction. On the other hand, when the angle formed by the horizontal plane and the inclined portion exceeds 45 degrees, the water-permeable member is not “the bottom surface of the water-permeable member rides above the inclined portion”, but “the inclined portion is formed on the side surface of the water-permeable member. The tendency to be pressed is increased, and it becomes difficult to push up the valve member by the inclined portion. In the invention of the second embodiment of Patent Document 2, in order to achieve the required action, the angle formed between the horizontal plane and the inclined portion needs to be within 45 degrees, and therefore a width of about 12 millimeters in the vertical direction is required. In the configuration of the second embodiment of Patent Document 2 in which the inclined portion has a width of 12 mm or more in the horizontal direction and the protrusion is advanced and retracted toward the center of the drain pipe, the tip of the protrusion is the drain pipe. Even if it does not reach the center, it needs to protrude 12 millimeters or more, and the cleanability is still poor. Furthermore, when the inclined portion of the protrusion pushes up the valve member in this way, it is necessary to apply a stress exceeding the friction generated between the valve member and the protrusion to the protrusion, There was also a problem that a large force was required for the pushing operation.
The present invention has been invented in view of the above problems, and in the remote-operated drain plug device, the strength of the member is made high, and the protrusion of the mechanism portion into the drain pipe is made as small as possible. The present invention provides a remote-operated drain plug device with improved cleanability.

Finally, the tapered portion 3b passes over the inclined surface 7a and rides on the flat upper surface of the elevating member 7, so that the state where the drain port 1a is opened is maintained. At this time, the annular support portion 4 does not move in contact with the inner surface of the drain port main body 1 and functions as a guide so that the valve shaft 2b is not inclined.
When the valve shaft 2b is raised, the valve shaft 2b is made of metal and has a smooth surface as described above. Therefore, when the valve shaft 2b is raised, the cylinder of the valve shaft 2b and the annular support portion 4 is raised. Friction hardly occurs between the portion 4b and the valve shaft 2b is raised smoothly.
If there is drainage or water discharge in the wash bowl S1 when the drainage port 1a is opened, drainage flows from the drainage port 1a through the inside of the drainage port main body 1, the joint pipe 8, and the trap pipe 10, and finally underfloor piping. Wastewater is discharged from the sewage side. Moreover, since drainage accumulates in the sealing part 10a of the trap pipe 10 to form sealing water, it is possible to prevent odors from the sewage side and invading pests into the indoor side.
When the operation unit 5 is operated again from the state where the drainage port 1a is opened and the operation body 5a is raised, the inner wire 6b is retracted toward the operation body 5a, and the elevating member 7 is also attached to the inner wire 6b. Return to position 4. As a result, the annular support portion 3 of the valve member 2 loses the support of the elevating member 7 and descends, and the valve shaft 2b and the valve body 2a are also lowered accordingly, so that the valve body 2a covers the drain port 1a and the drain port Close 1a.
Thereafter, by performing a push-pull operation on the operation body 5a, the drain port 1a can be opened and closed by remote control at the operation unit 5 located at a position separated from the drain port 1a. The remote-operated drain plug device of the present embodiment is called a two-way remote-operated drain plug device because the drain port 1a is opened and closed by pushing and pulling the operation body 5a in two directions. .

In the above operation, the length of pushing and pulling of the operating body 5a is about 15 millimeters which is the length width of the inclined surface 7a in the axial direction of the elevating member 7 (more precisely, the horizontal surface of the elevating member 7 exceeds the inclined surface 7a). On the other hand, the ascending width of the valve body 2a is 2 with respect to the width of 12 mm in the vertical direction of the inclined surface 7a until the state changes from FIG. 4 to FIG. Since there is a play width of about millimeters, it is about 10 millimeters.
In the above operation, as described above, the inclined surface 7a has an angle of about 39 degrees, which is 15 millimeters in the lateral direction as viewed from the side and 12 millimeters in the vertical direction, and is gentler than 45 degrees with respect to the horizontal plane. Is made. For this reason, the taper part 3b of the annular support part 3 of the valve member 2 can easily ride on the inclined surface 7a.
On the other hand, the width of the protrusion of the elevating member 7 to the inner surface of the drain pipe (the inner surface of the pipe body portion of the joint pipe 8) is always 4 mm regardless of the open / close state of the drain port 1a. The projection width can be very small for a diameter of 38 millimeters.
Further, since the elevating member 7 does not have a rotating structure as in the conventional example, the elevating member 7 can be made thick enough to obtain a required strength. For example, when the elevating member 7 is provided with a thickness exceeding 4 millimeters in plan view, the elevating member 7 is configured to advance and retreat outside the inner surface of the planar view tube body portion as in this embodiment. The width of the protrusion to the inner surface of the tube portion can be 4 millimeters while the wall thickness itself exceeds 4 millimeters.
Further, when the elevating member 7 moves forward along the guide portion 8a, friction occurs at the contact portion between the tapered portion 3b and the elevating member 7, but the following 1. 2. For this reason, the friction generated between the two is not particularly problematic.
1. Since the contact portion on the valve member 2 side is the tapered portion 3b, the contact portion with the elevating member 7 is an area having a very small area such as a point or a line, and hardly causes friction and can be operated smoothly.
2. The inner surface of the joint pipe 8 has a circular shape, and the annular support portion 4 and the valve shaft 2b are configured to be rotatable as described above. For this reason, when the friction between the taper portion 3b and the elevating member 7 is large, the annular support portion 3 and the valve shaft 2b are formed in an annular shape while the taper portion 3b and the elevating member 7 do not slip and remain stationary due to friction. By rotating with respect to the support portion 4, the elevating member 7 can be advanced without applying a large force exceeding the static friction force. Note that the valve shaft 2b and the annular support portion 4 can rotate smoothly without friction as described above, and the problem of friction does not occur.

Next, a second embodiment of the present invention will be described with reference to the drawings.
The remote-operated drain plug device of the second embodiment of the present invention shown in FIGS. 7 to 14 is applied to a wash bowl S1 as a tank body described below, and will be described below. , The drain port body 1, the joint pipe 8, the mechanism part, the release wire 6 as the operation transmission member, the valve member 2, the operation part 5, and the trap pipe 10.
Among the above configurations, the drain port main body 1, the valve member 2, the operation unit 5, and the trap pipe 10 are the same as those in the first embodiment described in paragraph 0013, so that the description thereof is omitted and there is a difference in configuration. Only the joint pipe 8, the mechanism part, and the release wire 6 as the operation transmission member will be described below.
The joint pipe 8 is a member provided with a tube portion made of a substantially straight cylinder, to which the lower end of the drain port main body 1 is connected at the upper end thereof. A cap nut having a female screw threadedly engaged with the screw is provided.
Further, the joint pipe 8 includes, on the side surface thereof, a mechanism portion composed of an elevating member 7 described below and a guide portion 8a for rotating the elevating member 7 in accordance with the operation of the release wire 6. .
As shown in FIG. 11, the elevating member 7 has a spiral shape that is concentric with the cylindrical portion and has a rotation of less than 360 degrees (about 180 degrees in this embodiment) above the cylindrical shape having a height of about 10 millimeters. (In the present embodiment, the inclined surface 7a functions as an inclined portion). The height difference from the upper end to the lower end of the spiral shape is about 15 millimeters. The radius of the lower cylindrical portion and the spiral arc is about 7 millimeters, and the outer circumference of the spiral portion (the outer circumference in the 180 degree range) is about 22 millimeters. The angle formed by the inclined surface 7a is about 35 degrees. Moreover, the connection part which can connect the edge part of the inner wire 6b of the release wire 6 is provided in the position of the cylindrical part near the inclined surface 7a which does not have the inclined surface 7a. In the connection portion, the end portion of the inner wire 6b is rotatably connected, and the connection with the end portion of the inner wire 6b is maintained when the elevating member 7 rotates about the rotation shaft 7b as described later. It can rotate smoothly. Hereinafter, the central axis of the inclined surface 7a, which becomes the axis of rotation when the elevating member 7 rotates, is referred to as “rotating shaft 7b”.
The guide portion 8a is a cylindrical portion that houses a part of the elevating member 7 so as to be rotatable therein. One end is closed and the other end is opened to the outside of the joint pipe 8 and provided inside. The elevating member 7 is arranged in the following positional relationship by the groove formed and a spacer 9 described later.
In the side view, the elevating member 7 is disposed so that the rotation shaft 7b is in the vertical direction, and is disposed so as to be rotatable in the horizontal direction around the rotation shaft 7b.
In plan view, the lifting member 7 is a part of the outer periphery of the inclined surface 7a that forms the spiral shape of the lifting member 7 in the vicinity of the circumferential portion of the inner surface of the joint pipe 8 that is substantially circular. It is arranged so as to be rotatable at a position protruding inside the part.
As is clear from the plan views shown in FIGS. 12 to 14 (FIGS. 12A, 13A, and 14A), the elevation member 7 has an arc portion in plan view. Because of the structure that only rotates within the cylindrical portion of the joint pipe 8, the protruding length of the elevating member 7 in the center direction with respect to the arc is constant regardless of the rotation of the elevating member 7. In the present embodiment, the inner diameter of the tube portion where the elevating member 7 is arranged is about 38 mm, whereas the protruding length of the elevating member 7 in the center direction with respect to the arc is about 4 mm. The other part is arranged on the outer part of the arc formed by the inner surface of the joint pipe 8 (the rotary shaft 7b of the elevating member 7 is also outside the arc of the joint pipe 8). In addition, about the guide part 8a, depending on the flow of drainage, drainage may flow into the guide part 8a from the opening connected to the guide part 8a provided on the side surface of the joint pipe 8, but it flows into the guide part 8a from the opening. The drainage does not flow downstream unless it returns from the opening to the joint pipe 8 again. Accordingly, the inside of the guide portion 8a does not correspond to the “drainage flow path”.
Moreover, the above-mentioned location where the elevating member 7 protrudes inside the arc of the inner surface of the joint pipe 8 will be referred to as “projection location 8b”.
Further, as a member to be inserted into the guide portion 8a, after the elevating member 7 is disposed in the guide portion 8a, the elevating member 7 is prevented from being displaced from a predetermined position, and the tube portion and the guide portion 8a intersect. Among the opening portions to be opened, a spacer 9 that closes a portion unnecessary for the operation of the elevating member 7 and that does not disturb the operation of the release wire 6 is provided.
The release wire 6 is a member for transmitting the operation applied to the operation unit 5 to the mechanism unit. The release wire 6 has a cylindrical outer tube 6a having rigidity in the axial direction and flexibility in the side surface direction. The inner wire 6b operates slidably in the outer tube 6a and has rigidity in the axial direction and flexibility in the side surface direction. In addition, a cap member 6c that closes the end of the outer tube 6a in a watertight manner while fixing the end of the outer tube 6a is provided at the end connected to the joint pipe 8 side. The end of the inner wire 6b on the mechanism part side is attached to the elevating member 7 so as to be rotatable without hindering the rotation of the elevating member 7. For this reason, the raising / lowering member 7 can rotate centering on the rotating shaft 7b with respect to the advance / retreat of the inner wire 6b.
As in the first embodiment, a tube body through which the wastewater flowing in from the drainage port 1a passes through the members is referred to as a “drainage pipe”. In each of the above members, the drain outlet body 1, the joint pipe 8, and the trap pipe 10 are “drain pipes”, and the drain outlet body 1 and the joint pipe 8 are “drain pipes arranged immediately below the drain outlet 1a”. (The trap pipe 10 is a drain pipe in which only a part on the upstream side is disposed at a position directly below the drain port 1a).

The remote-operated drain plug device of the second embodiment configured as described above is applied to the wash bowl S1, which is a tank body, as follows. Even if not specifically described, the connection locations of the respective members are connected in a watertight manner as necessary by screw connection using an adhesive or packing.
First, the drain port main body 1 is inserted into the mounting hole H1 provided on the bottom surface of the wash bowl S1, and the lower surface of the flange portion 1b is brought into contact with the upper peripheral surface of the mounting hole H1.
Next, the female screw of the plate nut member 1c is screwed into the male screw of the drain body 1 and the peripheral edge of the mounting hole H1 is sandwiched between the lower surface of the flange portion 1b and the upper surface portion of the plate nut member 1c, and is attached to the wash bowl S1. Fix it.
Next, the operation part main body 5b is fixed to the operation part attachment hole H2.
Next, the elevating member 7 is rotatably connected to one end of the inner wire 6b on the mechanism part side of the release wire 6, and then the elevating member 7 is inserted into the guide portion 8a of the joint pipe 8, and the protruding portion 8b. A part of the inclined surface 7a of the elevating member 7 projects so that the elevating member 7 is rotatable about the rotation shaft 7b. Further, the spacer 9 is inserted into the guide portion 8a to prevent the position of the elevating member 7 from being displaced, and the end of the guide portion 8a is closed with the cap member 6c. At this time, the end portion of the outer tube 6a on the mechanism portion side of the release wire 6 is fixed to the end portion of the guide portion 8a by the cap member 6c.
Next, the upstream end of the tube portion of the joint pipe 8 is connected to the lower end of the drain port body 1, and the downstream end is connected to the upstream end of the trap pipe 10. Further, the downstream end of the trap pipe 10 is connected to the sewage side pipe.
Next, the end of the inner wire 6b on the operation unit 5 side of the release wire 6 is connected and fixed to the lower end of the operation body 5a, and the end of the outer tube 6a on the operation unit 5 side is connected and fixed to the lower end of the operation unit main body 5b.
Furthermore, the valve member 2 is disposed from the drain port 1a in the drain port body 1 to the joint portion 8 to complete the construction of the remote-operated drain plug device of this embodiment.

Next, the operation of the remote-operated drain plug device of the second embodiment will be described with reference to FIGS. 4 to 6, the valve member 2 is omitted in the drawings of (a) and (b), and the joint pipe 8, the outer tube 6a, the cap member 6c, and the spacer 9 are arranged in the middle of the guide portion 8a. It is cut out at the height position, and the elevating member 7 and the inner wire 6b are shown not cut out.
When using the remote control type drain plug device of the second embodiment, as shown in FIG. 12, first, the operation body 5a of the operation unit 5 is operated, and the drain port 1a is covered with the valve member 2 so that the drain port 1a is covered. Closed.
At this time, the operation body 5a rises, and thereby the elevating member 7 and the inner wire 6b are in a state of being retracted to the operation portion 5 side.
When the push-in operation is performed on the operating body 5a from this state and the elevating member 7 is rotated via the inner wire 6b, the inclined surface 7a of the elevating member 7 is brought into a position in contact with the tapered portion 3b as shown in FIG. Then, with the rotation of the elevating member 7, the annular support portion 3 having the tapered portion 3b is supported by the inclined surface 7a of the elevating member 7 and rises, so that the valve body 2a is also raised together with the valve shaft 2b. The valve body 2a is separated from the port 1a, and the drain port 1a is opened as shown in FIG. In this embodiment, the rotation of the elevating member 7 is fixed by the friction between the operating body 5a and the operating portion main body 5b, and thereby the rise of the valve member 2 pushed up by the elevating member 7 is also fixed. The state where the drain port 1a is opened is maintained. At this time, the annular support portion 4 does not move in contact with the inner surface of the drain port main body 1 and functions as a guide so that the valve shaft 2b is not inclined.
When the valve shaft 2b is raised, the valve shaft 2b is made of metal and has a smooth surface as described above. Therefore, when the valve shaft 2b is raised, the cylinder of the valve shaft 2b and the annular support portion 4 is raised. Friction hardly occurs between the portion 4b and the valve shaft 2b is raised smoothly.
If there is drainage or water discharge in the wash bowl S1 when the drainage port 1a is opened, drainage flows from the drainage port 1a through the inside of the drainage port main body 1, the joint pipe 8, and the trap pipe 10, and finally underfloor piping. Wastewater is discharged from the sewage side. Moreover, since drainage accumulates in the sealing part 10a of the trap pipe 10 to form sealing water, it is possible to prevent odors from the sewage side and invading pests into the indoor side.
When the operation unit 5 is operated again from the state where the drainage port 1a is opened and the operation body 5a is raised, the inner wire 6b is retracted to the operation body 5a side. It rotates in the reverse direction and returns to the position shown in FIG. As a result, the annular support portion 3 of the valve member 2 loses the support of the elevating member 7 and descends, and the valve shaft 2b and the valve body 2a are also lowered accordingly, so that the valve body 2a covers the drain port 1a and the drain port Close 1a.
Thereafter, by performing a push-pull operation on the operation body 5a, the drain port 1a can be opened and closed by remote control at the operation unit 5 located at a position separated from the drain port 1a. The remote-operated drain plug device of the present embodiment is called a two-way remote-operated drain plug device because the drain port 1a is opened and closed by pushing and pulling the operation body 5a in two directions. .

In the above operation, the angle between the inclined surface 7a and the horizontal plane is an angle of about 35 degrees, which is gentler than 45 degrees. For this reason, the taper part 3b of the annular support part 3 of the valve member 2 can easily ride on the inclined surface 7a.
On the other hand, the width of the protrusion of the elevating member 7 to the inner surface of the drain pipe (the inner surface of the pipe body portion of the joint pipe 8) is always 4 mm regardless of the open / close state of the drain port 1a. The projection width can be very small for a diameter of 38 millimeters.
Further, since the elevating member 7 does not have a structure that rotates in the vertical direction as in the conventional example, the elevating member 7 can be made thick enough to obtain a required strength. For example, when the elevating member 7 is provided with a thickness exceeding 4 millimeters in plan view, the elevating member 7 is configured to advance and retreat outside the inner surface of the planar view tube body portion as in this embodiment. The width of the protrusion to the inner surface of the tube portion can be 4 millimeters while the wall thickness itself exceeds 4 millimeters.
Further, when the elevating member 7 moves forward along the guide portion 8a, friction occurs at the contact portion between the tapered portion 3b and the elevating member 7, but the following 3. 4. For this reason, the friction generated between the two is not particularly problematic.
3. Since the contact portion on the valve member 2 side is the tapered portion 3b, the contact portion with the elevating member 7 is an area having a very small area such as a point or a line, and hardly causes friction and can be operated smoothly.
4). The inner surface of the joint pipe 8 has a circular shape, and the annular support portion 4 and the valve shaft 2b are configured to be rotatable as described above. For this reason, when the friction between the taper portion 3b and the elevating member 7 is large, the annular support portion 3 and the valve shaft 2b are formed in an annular shape while the taper portion 3b and the elevating member 7 do not slip and remain stationary due to friction. By rotating with respect to the support portion 4, the elevating member 7 can be advanced without applying a large force exceeding the static friction force. Note that the valve shaft 2b and the annular support portion 4 can rotate smoothly without friction as described above, and the problem of friction does not occur.

Next, a third embodiment of the present invention will be described with reference to the drawings.

Furthermore, the valve member 2 is disposed from the drain port 1a in the drain port body 1 to the joint portion 8 to complete the construction of the remote-operated drain plug device of this embodiment.

Next, the operation of the remote control drain plug device of the third embodiment will be described.
When using the remote-operated drain plug device of the third embodiment, as shown in FIG. 17, first, an operation is performed on the operation body 5a of the operation unit 5, and the drain port 1a is covered by the valve member 2 so that the drain port 1a is covered. Closed.
At this time, the operation body 5a rises, and thereby the elevating member 7 and the inner wire 6b are in a state of being retracted to the operation portion 5 side.
At this time, the elevating member 7 is completely stored in the guide portion 8a.
When the pushing operation is performed on the operation portion 5 from this state and the pushing operation is performed on the shaft portion of the lock mechanism, the shaft portion is fixed in a state of projecting to the mechanism portion side by about 15 millimeters, and accordingly, the shaft is raised and lowered together with the inner wire 6b. The member 7 also advances.
As a result, as shown in FIG. 18, the tip portion of the elevating member 7 reaches a position in contact with the inclined surface 7 a of the valve obstructing portion, and thereafter the annular bearing portion 3 having the inclined surface 7 a as the elevating member 7 advances. Is supported and lifted by the elevating member 7, so that the valve body 2a is also lifted together with the valve shaft 2b, and the valve body 2a is separated from the drain port 1a.
Due to the action of the locking mechanism, the advancement of the elevating member 7 is maintained and fixed in a state where the elevating member 7 is in contact with the intermediate position of the inclined surface 7a of the valve member 2, so that the state in which the drain port 1a is opened is maintained. At this time, the annular support portion 4 does not move in contact with the inner surface of the drain port main body 1 and functions as a guide so that the valve shaft 2b is not inclined.
When the valve shaft 2b is raised, the valve shaft 2b is made of metal and has a smooth surface as described above. Therefore, when the valve shaft 2b is raised, the cylinder of the valve shaft 2b and the annular support portion 4 is raised. Friction hardly occurs between the portion 4b and the valve shaft 2b is raised smoothly.
If there is drainage or water discharge in the wash bowl S1 when the drainage port 1a is opened, drainage flows from the drainage port 1a through the inside of the drainage port main body 1, the joint pipe 8, and the trap pipe 10, and finally underfloor piping. Wastewater is discharged from the sewage side. Moreover, since drainage accumulates in the sealing part 10a of the trap pipe 10 to form sealing water, it is possible to prevent odors from the sewage side and invading pests into the indoor side.
When the operation portion 5 is pushed again from the state where the drainage port 1a is opened and the shaft portion of the locking mechanism is released, the inner wire 6b is moved together with the shaft portion of the locking mechanism by the action of the return spring. The lifting member 7 also returns to the position shown in FIG. 17 along with the inner wire 6b. As a result, the annular support portion 3 of the valve member 2 loses the support of the elevating member 7 and descends, and the valve shaft 2b and the valve body 2a are also lowered accordingly, so that the valve body 2a covers the drain port 1a and the drain port Close 1a.
Thereafter, by performing a pushing operation on the operation body 5a, the drainage port 1a can be opened and closed by remote operation at the operation unit 5 located away from the drainage port 1a.
The remote-operated drain plug device of the present embodiment is called a one-way remote-operated drain plug device because it opens and closes the drain port 1a only by pushing the operation body 5a.

In the above operation, the length of pushing of the operating body 5a is about 15 millimeters as described above, and the ascending width of the valve body 2a, that is, the vertical width of the portion of the inclined surface 7a where the elevating member 7 contacts. Is about 10 millimeters, the positional relationship between the valve member 2 and each member such as the mechanism is adjusted at the design time.
Further, the width of the protrusion of the elevating member 7 to the inner surface of the drain pipe (the inner surface of the pipe portion of the joint pipe 8) is always 4 millimeters regardless of whether the drain port 1a is opened or closed, and the tubular body having a rectangular shape. The protrusion width can be very small with respect to the length of one side of the inner surface of the portion of about 21 millimeters.
Further, since the elevating member 7 does not have a rotating structure as in the conventional example, the elevating member 7 can be made thick enough to obtain a required strength. For example, when the elevating member 7 is provided with a thickness exceeding 4 millimeters in plan view, the elevating member 7 is configured to advance and retreat outside the inner surface of the planar view tube body portion as in this embodiment. The width of the protrusion to the inner surface of the tube can be 4 millimeters while the wall thickness itself exceeds 4 millimeters.

  In the first embodiment to the third embodiment, the width of the protrusion of the elevating member 7 toward the center of the drain pipe in the plan view is about 4 millimeters. The width of this protrusion matches the general thickness of 3 mm required for the valve member 2 when moving the valve member 2 up and down, and the clearance between the valve member 2 and the inner surface of the tube portion, about 1 mm at the maximum. However, the width of the protrusion in the plan view can be freely adjusted as long as it is within the range where the cleaning property can be improved. Specifically, as described above, it is sufficient to raise and lower the valve member 2 from the member dimensions, and is sufficiently narrow with respect to the width as narrow as possible, or the diameter of the tube portion, and has good cleaning properties. It is preferable that the protruding width be within a range of about 5% to 20% of the inner diameter of the tube portion that can be secured.

  Moreover, in the said 1st Example thru | or 3rd Example, although it is the structure which raises / lowers the valve member 2 using an inclined part (an inclined surface 7a in an Example), this inclined part (inclined surface 7a) is. The structure is such that the valve body 2a can be raised by about 10 millimeters by applying an operation within 15 millimeters to the operation body 5a while the angle formed with the horizontal plane is gentler than 45 degrees. There is no inferior part to the conventional remote-operated drain plug device.

The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the above embodiment, all of the remote-operated drain plug devices are constructed on the wash bowl S1 of the wash basin S, but the present invention is not limited to the above embodiment, and a bathroom provided with a bathtub as a tank body. Any tank body of any drainage device may be used as long as it is a tank body having a drain port 1a, such as a sink with a sink as a tank body.

  Moreover, in the said 1st Example, although the valve member 2 rides on the horizontal part of the raising / lowering member 7, the open state of the drain port 1a is maintained, This invention is not limited to the said Example, The opening state of the drainage port 1a may be maintained while the valve member 2 rides on the inclined surface 7a of the elevating member 7 by using friction between the operation body 5a and the operation unit 5. .

  In the first embodiment, no particular configuration is provided at the tip of the elevating member 7, but a rod-like portion is provided at the tip of the elevating member 7, and a hole for guiding the rod-like portion is provided in the mechanism portion. The elevating member 7 may be configured to be able to advance and retract more stably.

  Further, in the third embodiment, in the configuration in which the valve member 2 is provided with the inclined portion, the tube portion of the joint pipe 8 is not a cylindrical shape but a square shape in plan view, and the annular portion 3a of the annular support portion 3 is also combined. Although it has a square shape in plan view, the present invention is not limited to the above-described embodiments, and the tubular portion and the annular portion 3a have a circular shape in plan view as in the first and second embodiments. Thus, an inclined portion may be provided on the annular support portion 3. However, in this case, it is necessary to provide an anti-rotation structure using, for example, a rib so that the annular support portion 3 does not rotate with respect to the advance / retreat of the elevating member 7.
