Description

  The present invention relates to a remote-operated drain plug device for remotely opening and closing a valve body of a drain outlet such as a bathtub or a wash basin.

Conventionally, a valve body is provided at a drainage outlet of a tank body such as a bathtub or a wash basin as shown in FIG. 10, and the valve body is operated by operation of an operation portion configured at the upper edge of the tank body as shown in FIG. A remote-operated drain plug device is well known that moves up and down to drain / stop the drainage in the tank.
This remote-operated drain plug device is as follows.
It is comprised from the tank body as a bathtub, a drain outlet, a drain plug, a valve lid, an operation part, a mechanical box, and a release wire.
The tank body is a box body and has a drain opening at the bottom. In this conventional example, a bathtub provided in a bathroom is used as a tank body.
The drain port is a hole opened in the bottom of the bathtub, and drains the tank body from the drain port. Moreover, the drain plug mentioned later is provided.
The drain plug is a member having a flange threaded on the outer periphery and protruding outward at the upper end, and constitutes a seating surface of the valve lid. The drain plug is finally connected to the sewer pipe via an elbow member or a drain trap, which is a drain piping member.
The valve lid is a member that closes / opens the drain port and drain plug. The drain port is closed when the valve lid is seated on the drain plug, and the drain port is opened when the valve lid is raised. ing.
An operation part is a push button comprised in the upper edge part of a bathtub, Comprising: When a user performs pushing operation suitably, it is comprised so that the said valve lid may raise / lower. In addition, the operation portion incorporates a return spring for retreating the progress caused by the operation of the operation portion of the inner wire of the release wire described later. This return spring is always urged in the extending direction, and is provided so as to always pull back the inner wire to the operation portion side.
The release wire is a member connected from the operation unit to the drain port, and is composed of an outer tube of a flexible tube having a hollow inside and an inner wire of a metal coil wire that is disposed so as to be able to advance and retract in the outer tube. Is done. The outer tube is connected from the operation unit to the lower end of the mechanical box described later, and the inner wire is connected and connected from the shaft of the operation unit to the support shaft of the mechanical box described later.
The mechanical box is a cylindrical box and includes a support shaft connected to the valve lid. The mechanical box has a built-in lock mechanism that locks up / down of the support shaft. In this conventional example, a thrust lock mechanism that is adopted in a ballpoint pen core knock structure is built in. The thrust lock mechanism includes a groove and a rotating cam surface on the inner periphery of the mechanical box, and a rotating cam surface configured above the inner surface of the mechanical box. The mechanical box is arranged and fixed at the center of the drain outlet by a fixing member attached to the drain plug.
The support shaft is disposed in the mechanical box so as to be movable up and down, the upper end is connected to the valve lid, and the lower end is connected to the tip of the inner wire of the release wire.

The above-described conventional remote-operated drain plug device operates as follows.
When the user pushes the operating part while the valve lid is seated on the drain, the inner wire of the release wire advances in the outer tube along with the operation of the operating part. Act on. Then, the support shaft rises as the inner wire advances, and the thrust lock mechanism locks the rise of the support shaft. Then, the valve lid connected to the upper end of the support shaft rises as the support shaft rises, and the drain port is opened. At this time, the return spring of the operating portion is compressed as the inner wire advances.
Further, when the user further pushes the operating portion, the inner wire of the release wire advances a little from the operating portion, the support shaft to which the inner wire is connected rises slightly, and the thrust lock mechanism is unlocked. When the lock is released, the compressed return spring of the operating portion is elastically urged outward and urged, and the inner wire moves backward by the amount of advancement toward the operating portion by the urging force of the return spring. When the inner wire is retracted, the support shaft connected to the tip of the inner wire is also lowered, and the valve lid connected to the support shaft is also lowered to be seated on the drain plug (drain port). Thus, the drain port is closed by the valve lid.
Moreover, the vertical movement of the valve lid is repeated by repeating the operation.

The above-described conventional remote-operated drain plug device has the following drainage flow.
When the valve lid is lowered and seated on the drain plug and the drain port is closed, the drain port is closed so that the drainage is stored in the bathtub. In addition, when the user operates the operation unit from this state, the valve lid of the drain port rises and the drain port is opened. Then, the drainage in the bathtub is drained from the opened drainage port, and finally drained to the sewer pipe through the elbow member disposed under the bathtub and the drain trap disposed in the washing place.
In this way, the drainage in the bathtub is drained into sewage.

However, the conventional remote-operated drain plug device has the following problems.
In the remote-operated drain plug device, since a valve lid is formed at the drain outlet at the bottom of the bathtub or wash bowl, the user may naturally step on it or place a bucket or the like, for example, during cleaning. Even if the user steps on the valve lid when it is raised, and even if the valve lid is closed, by pushing the operation part with the user or a bucket stepping on the valve lid, Excessive stress may be applied to the support shaft.
In addition, when such an excessive stress occurs, since the mechanical box that is the lock mechanism of the support shaft is arranged inside the drain outlet, the stress of the support shaft is directly applied to the lock mechanism of the mechanical box, The lock mechanism itself was destroyed by stress. Thus, in the conventional remote-operated drain plug device of the type in which the mechanical box is provided inside the drain port, no countermeasure has been taken when excessive stress is applied to the support shaft.

When the lock is released, the return spring 5 is compressed by the urging force, and the support shaft 31 is compressed. 31 will descend.

The above-described remote-operated drain plug device operates as follows.
When the user pushes the operation portion 8 while the valve lid 6 is seated on the drain outlet 2 as shown in FIG. 1A, the inner wire 72 of the release wire 7 is moved along with the operation of the operation portion 8. It advances in the outer tube 71 and comes into contact with the recess 34 of the support shaft case 32 in the mechanical box 3 of the drain port 2. Then, the support shaft case 32 and the support shaft 31 are raised as the inner wire 72 advances, and the thrust lock mechanism locks the rise of the support shaft 31. At this time, since the spring of the shock absorber 4 does not act at all with the degree of stress applied to this operation, the support shaft 31 moves up as the support shaft case 32 rises. Then, as shown in FIG. 1 (b), the valve lid 6 connected to the upper end of the support shaft 31 rises as the support shaft 31 rises, and the drain port 2 is opened. At this time, the return spring 5 in the mechanical box 3 is compressed as the support shaft 31 is raised. When the user stops pushing the operating portion 8, the return spring 5 of the release wire 7 acts, the inner wire 72 moves backward, and the contact between the tip of the inner wire 72 and the support shaft case 32 is released.
Further, when the user further pushes the operation portion 8, the inner wire 72 of the release wire 7 slightly advances from the operation portion 8, and the inner wire 72 comes into contact with the recess 34 of the support shaft case 32 to support the support shaft case 32. The shaft 31 is lifted slightly, and the thrust lock mechanism is unlocked. When the lock is released, the compressed return spring 5 in the mechanical box 3 is ejected and urged outward, and the support shaft 31 and the support shaft case 32 can be lowered by the urging force of the return spring 5. it can. When the support shaft 31 is lowered, the valve lid 6 is also lowered and seated on the drain plug 21 (drain port 2) as shown in FIG. In this way, the drain port 2 is closed by the valve lid 6. When the user stops pushing the operating portion 8, the return spring 5 of the release wire 7 acts, the inner wire 72 moves backward, and the contact between the tip of the inner wire 72 and the support shaft case 32 is released.
Further, the vertical movement of the valve lid 6 is repeated by repeating the operation.

The remote-operated drain plug device of this embodiment described above has the following drainage flow.
When the valve lid 6 is lowered and seated on the drain plug 21 and the drain port 2 is closed, the drain port 2 is closed, so that drainage is stored in the bathtub. Further, when the user operates the operation unit 8 from this state, the valve lid 6 of the drain port 2 rises and the drain port 2 is opened. Then, the drainage in the bathtub is drained from the drainage port 2 that has been opened, and finally drained to the sewer pipe through the elbow member disposed under the bathtub and the drain trap disposed in the washing area.
In this way, the drainage in the bathtub is drained into sewage.

The shock absorber 4 of the remote-operated drain plug device operates as follows.
If an excessive stress is applied to the valve lid 6 by stepping on the valve lid 6 when opening the plug, the stress is applied to the support shaft 31 and the lock mechanism is stressed. The stress is transmitted to the existing shock absorber 4. Then, the shock absorber 4 is compressed, and the support shaft 31 is lowered and enclosed in the support shaft case 32 as shown in FIG. Then, the valve lid 6 connected to the support shaft 31 also descends as the support shaft 31 descends, and the stress and impact applied to the valve lid 6 can be absorbed. As a result, the support shaft case 32 provided with the rotation cam 35 serving as a lock mechanism can be lowered only the support shaft 31 without being lowered, so that the shock absorber 4 can absorb an impact without damaging the lock mechanism. .
When the stress disappears, the compression of the spring inside the shock absorber 4 is released, and it is elastically urged in the vertical direction. Then, the support shaft 31 is raised by the urging force of the shock absorber 4 and the valve lid 6 can also be raised, so that it can be easily returned to the open state as shown in FIG.

(Second Embodiment) The remote-operated drain plug device of this embodiment is provided with a valve body in the drain port 2 of the tank body 1 such as a bathtub or a wash basin as shown in FIG. A remote-operated drain plug device that moves the valve body up and down by operating the operation unit 8 configured as described above to drain / stop the drainage in the tank body 1 is well known.

The thrust lock mechanism includes a groove and a rotating cam surface on the inner periphery of the mechanical box 3 and a rotating cam surface formed above the inner surface of the mechanical box 3. Since the operation of the thrust lock mechanism is conventionally known, the description thereof is omitted.
The shock absorber 4 is a spring that is housed in the support shaft 31, and the lower side of the shock absorber 4 is placed on the upper surface of the guide shaft 33 and is substantially housed in the support shaft 31. The spring is always urged in the extending direction and does not act on the rising stress of the inner wire 72, but acts on a great amount of stress applied to the support shaft 31 (that is, excessive stress applied to the valve lid 6). Then, it has an urging force enough to compress. Further, the upper end of the shock absorber 4 abuts on the support shaft 31.
The return spring 5 is a return spring for the support shaft 31 built in the mechanical box 3. A biasing force that constantly biases in the extending direction is provided. The biasing force of the return spring 5 is smaller than the biasing force of the shock absorber 4. In this embodiment, after being installed on the outer periphery of the support shaft 31, it is built in between the upper end of the support shaft case 32 and the upper surface of the mechanical box 3. Since the return spring 5 is built in the mechanical box 3, the support shaft 31 can be lowered by the force of the return spring 5, and the inner wire 72 is not connected to the support shaft 31, but is cut and arranged. Can do. Further, when the support shaft 31 is locked by the cam mechanism of the mechanical box 3, the return spring 5 is compressed. When the lock is released, the return spring 5 is compressed by the urging force, and the support shaft 31 is compressed. 31 will descend.

The above-described remote-operated drain plug device operates as follows.
When the user pushes the operating portion 8 while the valve lid 6 is seated on the drain outlet 2 as shown in FIG. 2A, the inner wire 72 of the release wire 7 is moved along with the operation of the operating portion 8. It advances in the outer tube 71 and comes into contact with the ceiling portion inside the guide shaft 33. Then, the support shaft case 32, the support shaft 31, and the guide shaft 33 are raised as the inner wire 72 advances, and the thrust lock mechanism locks the rise of the support shaft 31. At this time, since the spring of the shock absorber 4 does not act at all with the degree of stress applied to this operation, the support shaft 31 moves up in accordance with the rise of the guide shaft 33. Then, as shown in FIG. 2 (b), the valve lid 6 connected to the upper end of the support shaft 31 rises as the support shaft 31 rises, and the drain port 2 is opened. At this time, the return spring 5 in the mechanical box 3 is compressed as the support shaft 31 is raised. When the user stops pushing the operation portion 8, the return spring 5 of the release wire 7 acts, the inner wire 72 moves backward, and the contact between the distal end of the inner wire 72 and the guide shaft 33 is released.
Further, when the user further pushes the operation portion 8, the inner wire 72 of the release wire 7 slightly advances from the operation portion 8, and the inner wire 72 comes into contact with the inner ceiling of the guide shaft 33 to support the support shaft case 32 and the guide shaft. 33, the support shaft 31 is slightly raised, and the thrust lock mechanism is unlocked. When the lock is released, the compressed return spring 5 in the mechanical box 3 is elastically urged outward to urge the support shaft 31, the guide shaft 33, and the support shaft case 32 by the urging force of the return spring 5. Can be lowered. When the support shaft 31 is lowered, the valve lid 6 is also lowered and seated on the drain plug 21 (drain port 2) as shown in FIG. In this way, the drain port 2 is closed by the valve lid 6. When the user stops pushing the operating portion 8, the return spring 5 of the release wire 7 acts, the inner wire 72 moves backward, and the contact between the tip of the inner wire 72 and the support shaft case 32 is released.
Further, the vertical movement of the valve lid 6 is repeated by repeating the operation.
Further, the flow of drainage of the remote-operated drain plug device of the present embodiment is the same as that in paragraph 0019 and is omitted.

The shock absorber 4 of the remote-operated drain plug device operates as follows.
When opening the plug, if excessive stress is applied to the valve lid 6 by stepping on the valve lid 6 or the like, the support shaft 31 is excessively stressed, and is built into the support shaft 31 before the lock mechanism is stressed. Stress is transmitted to the shock absorber 4. Then, the shock absorber 4 is compressed between the upper surface of the guide shaft 33 and the ceiling inside the support shaft 31, and the support shaft 31 is lowered as shown in FIG. 2C to enclose the guide shaft 33 therein. Then, the valve lid 6 connected to the support shaft 31 also descends as the support shaft 31 descends, and the stress and impact applied to the valve lid 6 can be absorbed. As a result, the support shaft case 32 provided with the rotation cam 35 serving as a lock mechanism can be lowered only the support shaft 31 without being lowered, so that the shock absorber 4 can absorb an impact without damaging the lock mechanism. .
When the stress disappears, the compression of the spring inside the shock absorber 4 is released, and it is elastically urged in the vertical direction. Then, the support shaft 31 is raised by the urging force of the shock absorber 4 and the valve lid 6 can also be raised, so that it can be easily returned to the open state as shown in FIG.

(Third Embodiment) The remote-operated drain plug device of this embodiment is provided with a valve body at the drain port 2 of the tank body 1 such as a bathtub or a wash basin as shown in FIG. A remote-operated drain plug device that moves the valve body up and down by operating the operation unit 8 configured as described above to drain / stop the drainage in the tank body 1 is well known.
This remote-operated drain plug device is as follows.
It is comprised from the tank 1 as a bathtub, the drain port 2, the drain plug 21, the valve lid 6, the operation part 8, the mechanical box 3, and the release wire 7. As shown in FIG.
Further, in the present embodiment, the tank body 1, the drain port 2, the drain plug 21, the valve lid 6, and the operation portion 8 are the same as the embodiment described in the above paragraph 0017, and therefore will be omitted.
The release wire 7 is a member connected from the operation unit 8 to the drain port 2, and is an outer tube 71 of a flexible tube having a hollow inside, and an inner of a metal coil wire that is disposed so as to be able to advance and retreat in the outer tube 71. Wire 72. The outer tube 71 is connected from the operation unit 8 to the lower end of the mechanical box 3 which will be described later, and the inner wire 72 is configured to abut against the recess 34 at the lower end of the support shaft case 32 in the mechanical box 3 which will be described later from the shaft of the operation unit 8. Is done. A return spring 5 dedicated to returning the inner wire 72 is built in the release wire 7.
The mechanical box 3 includes a support shaft 31, a support shaft case 32, a lock mechanism, a shock absorber 4, and a return spring 5 inside. The mechanical box 3 is a cylindrical box having openings on the upper and lower surfaces. The support shaft 31 is inserted into the opening on the upper surface of the mechanical box 3, and the release wire 7 is inserted into the opening on the lower surface.
The support shaft 31 is a cylindrical member that is disposed in the mechanical box 3 so as to be movable up and down, has an upper end connected to the valve lid 6, and has a hollow inside. At this time, the support shaft 31 is inserted through the opening on the upper surface of the mechanical box 3 so as to be movable up and down. The lower end is configured as a non-detachable flange that protrudes outward, and the lower end is built into a support shaft case 32 described later.
The support shaft case 32 is a cylindrical case body for guiding the support shaft 31, and a rotation cam 35 of a lock mechanism described later is formed on the outer periphery. Further, a recess 34 is formed on the lower surface to come into contact with the inner wire 72 of the release wire 7 when it travels.
The lock mechanism incorporates a lock mechanism that locks the ascent / descent of the support shaft 31. In this embodiment, the lock mechanism incorporates a thrust lock mechanism that is employed in a ballpoint pen core knock structure. The thrust lock mechanism includes a groove and a rotating cam surface on the inner periphery of the mechanical box 3 and a rotating cam surface formed above the inner surface of the mechanical box 3. Since the operation of the thrust lock mechanism is conventionally known, the description thereof is omitted.
The shock absorber 4 is built in the support shaft case 32 from the support shaft 31, the lower side of the shock absorber 4 is placed on the inner bottom surface of the support shaft case 32, and the upper end is pressed against the inner ceiling of the support shaft 31. The spring is always biased in the extending direction. In addition, although it does not act on the rising stress of the inner wire 72, it has a biasing force that acts on and compresses a great amount of stress applied to the support shaft 31 (that is, excessive stress applied to the valve lid 6).
The return spring 5 is a return spring for the support shaft 31 built in the mechanical box 3. A biasing force that constantly biases in the extending direction is provided. The biasing force of the return spring 5 is smaller than the biasing force of the shock absorber 4. In this embodiment, after being installed on the outer periphery of the support shaft 31, it is built in between the upper end of the support shaft case 32 and the upper surface of the mechanical box 3. Since the return spring 5 is built in the mechanical box 3, the support shaft 31 can be lowered by the force of the return spring 5, and the inner wire 72 is not connected to the support shaft 31, but is cut and arranged. Can do. Further, when the support shaft 31 is locked by the cam mechanism of the mechanical box 3, the return spring 5 is compressed. When the lock is released, the return spring 5 is compressed by the urging force, and the support shaft 31 is compressed. 31 will descend.

The above-described remote-operated drain plug device operates as follows.
When the user pushes the operation portion 8 while the valve lid 6 is seated on the drain outlet 2 as shown in FIG. 3A, the inner wire 72 of the release wire 7 is moved along with the operation of the operation portion 8. It advances through the outer tube 71 and contacts the recess 34 of the support shaft case 32. Then, the support shaft case 32 and the support shaft 31 are raised as the inner wire 72 advances, and the thrust lock mechanism locks the rise of the support shaft 31. At this time, since the spring of the shock absorber 4 does not act at all with the degree of stress applied to this operation, the support shaft 31 moves up as the support shaft case 32 rises. Then, as shown in FIG. 3B, the valve lid 6 connected to the upper end of the support shaft 31 rises as the support shaft 31 rises, and the drain port 2 is opened. At this time, the return spring 5 in the mechanical box 3 is compressed as the support shaft 31 is raised. When the user stops pushing the operation portion 8, the return spring 5 of the release wire 7 acts, the inner wire 72 moves backward, and the contact between the tip of the inner wire 72 and the recess 34 of the support shaft case 32 is released. The
Further, when the user further pushes the operation portion 8, the inner wire 72 of the release wire 7 slightly advances from the operation portion 8, and the inner wire 72 comes into contact with the recess 34 of the support shaft case 32 to support the support shaft case 32. The shaft 31 is lifted slightly, and the thrust lock mechanism is unlocked. When the lock is released, the compressed return spring 5 in the mechanical box 3 is ejected and urged outward, and the support shaft 31 and the support shaft case 32 can be lowered by the urging force of the return spring 5. it can. When the support shaft 31 is lowered, the valve lid 6 is also lowered and seated on the drain plug 21 (drain port 2) as shown in FIG. In this way, the drain port 2 is closed by the valve lid 6. When the user stops pushing the operating portion 8, the return spring 5 of the release wire 7 acts, the inner wire 72 moves backward, and the contact between the tip of the inner wire 72 and the support shaft case 32 is released.
Further, the vertical movement of the valve lid 6 is repeated by repeating the operation.
Further, the flow of drainage of the remote-operated drain plug device of the present embodiment is the same as that in paragraph 0019 and is omitted.

The shock absorber 4 of the remote-operated drain plug device operates as follows.
If an excessive stress is applied to the valve lid 6 by stepping on the valve lid 6 at the time of opening, an excessive stress is applied to the support shaft 31 and the stress is applied to the lock mechanism. The stress is transmitted to the shock absorber 4 built in. Then, the shock absorber 4 is compressed between the ceiling inside the support shaft 31 and the lower surface inside the support shaft case 32, and the support shaft 31 is lowered and enclosed in the support shaft case 32 as shown in FIG. Then, the valve lid 6 connected to the support shaft 31 also descends as the support shaft 31 descends, and the stress and impact applied to the valve lid 6 can be absorbed. As a result, the support shaft case 32 provided with the rotating cam 35 teeth as the lock mechanism can be lowered only the support shaft 31 without being lowered, so that the shock absorber 4 can absorb the impact without damaging the lock mechanism. it can.
When the stress disappears, the compression of the spring inside the shock absorber 4 is released, and it is elastically urged in the vertical direction. Then, the support shaft 31 is lifted by the urging force of the shock absorber 4 and the valve lid 6 is also lifted, so that it can be easily returned to the open state as shown in FIG.

Moreover, although the embodiment of the remote control type drain plug device of the present invention is as described above, it is not limited to the embodiment, and can be appropriately changed within the scope of the claims.
For example, in the second embodiment, the shock absorber 4 is disposed between the support shaft 31 and the guide shaft 33. However, as shown in FIGS. It may be arranged between the bottom surfaces of the support shaft cases 32.
In the above embodiment, the tip of the inner wire 72 is separated from the lower end of the support shaft 31, the support shaft case 32, and the guide shaft 33. However, as shown in FIGS. The front end of the support 72, the support shaft 31, the support shaft case 32, and the lower end of the guide shaft 33 may be directly coupled and connected. With this configuration, only the return spring 5 of the release wire 7 needs to be disposed, and the return spring 5 of the support shaft 31 does not have to be configured inside the mechanical box 3.
Further, in the above embodiment, the return spring 5 is disposed in the mechanical box 3, but as shown in FIGS. 6A to 6C, a plurality or a single spring shaft is provided at the lower end of the support shaft case 32. Further, the spring shaft may be disposed so as to be movable up and down from the lower surface of the mechanical box 3, and the return spring 5 may be disposed on the spring shaft. In this way, since the height width of the return spring 5 minutes is not required to be arranged in the mechanical box 3, the height of the drain port 2 can be further reduced, and the floor can be lowered.
In the above embodiment, the return spring 5 is arranged in the mechanical box 3, but as shown in FIGS. 7A to 7C and 8, the bottom of the support shaft case 32 is connected to the gear. It is also possible to partially project and configure the return spring 5 at the location corresponding to the shape. In this way, the height width of the return spring 5 minutes can be reduced. Therefore, the height of the drain port 2 can be further reduced, and the floor can be lowered.
Further, although not shown, the return spring 5 may be constituted by a so-called taper spring that swells downward. If the taper spring is provided in this manner, the height width can be reduced while having the same urging force as that of a normal cylindrical spring, so that the height of the drain port 2 can be further reduced. it can.
FIG. 9 is a cross-sectional view of the mechanical box 3 according to another embodiment. However, a space for accommodating the return spring 5 can be formed on the outer periphery of the gear structure in the mechanical box. With this configuration, the height of the return spring 5 does not have to be configured separately, so that the height of the drain port 2 can be reduced.
