SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and an object thereof is to simplify the operation of connecting a release wire to an operation unit and to have a drain which does not expose metal fittings to the outside. A plug device is provided. Another purpose is to provide a drain plug device that does not cause the inner core to buckle even if the push button is pressed by mistake while the pressing force is applied to the plug lid by stepping on in the closed state. To provide. Still another object is to release the lock by pushing the push button from the open state in the container release wiring type drain cock device having the thrust lock mechanism as an operating part in the drain cock. An object of the present invention is to provide a drain plug device in which the inner core does not buckle even if a load is applied to the plug lid by mistake while the push button is not pressed.

[0005]

The technical means taken to solve the above-mentioned object is that of an operation unit connected via a release wire to a drain plug provided in a vessel such as a bathtub, a sink, a basin or the like. In a drain plug device for opening and closing the drain plug by a pushing operation, the release wire is formed by inserting one end of a release wire into a depressed recess formed in the operation part from a side opposite to a push button side in a push button case. The inner core protruding from the outer tube can be pushed with a push button, and the flange formed at one end of the outer tube of the release wire comes into contact with the washer member attached to the bottom of the concave recess, and it is fitted over the outer tube The other end of the ring-shaped member, one end of which is in contact with or close to the flange, is inserted into the insertion hole opened in the side of the push button case in communication with the concave portion, avoiding the release wire. And it is characterized in that it is directly or indirectly supported by the stop member to be engaged in the recessed portion Te (claim 1). The stop member has an open portion that does not interfere with the release wire at the time of insertion and has a front-view open shape in a plan view. A locking recess is formed on the inner surface of the recess to lock the stopper member inserted therein.
The term "indirectly supporting" refers to supporting via an intervening member, and an example of the intervening member includes an O-ring that closes the gap between the concave portion and the outer tube in a watertight manner. Further, the stop member is formed of a synthetic resin material such as POM.

According to the above-mentioned technical means, a washer member inserted from the recessed portion opening portion is brought into contact with the bottom of the recessed portion provided in the push button case, and then the ring-shaped member is externally fitted. In this state, insert one end of the release wire through the opening of the concave portion, and then insert the release wire through the insertion hole opened in the side of the push button case. To support the shaped member. As a result, the flange at one end of the outer tube of the release wire is supported so as not to come off by the washer member and the ring-shaped member supported by the stopper member, and the inner core protruding from the outer tube is vertically movable to the push button case. It can be pushed by the axis of the push button to be inserted. Therefore, one end of the release wire provided with the washer member and the ring-shaped member in the form of an external fitting is sequentially inserted from the open portion of the concave portion, and the release wire operating portion ( Specifically, the connection work to the push button case is completed.

In addition, the drain plug is opened and closed by a pushing operation of an operation unit connected to a drain plug provided on a container such as a bathtub, a sink, a basin, etc. via a release wire, and the operation unit is placed inside the container. In the drain plug device provided on the wall surface, an inner core protruding from the release wire by inserting one end of the release wire into a recessed portion recessed from the side opposite to the push button side in the push button case in the operation unit. Pushable with a push button,
The flange formed at one end of the outer tube of the release wire abuts against a washer member applied to the bottom of the recessed portion, and is provided on the outer tube so as to be fitted externally, and one end abuts or approaches the flange. The other end of the ring-shaped member is indirectly connected with the concave portion by a stopper member which is inserted around the inner core from the insertion hole opened in the side portion of the push button case and is locked in the concave portion. It is also effective when the means for indirectly supporting is an annular seal member interposed between the stopper member and the ring-shaped member to close the gap between the concave portion and the outer tube. (Claim 2). An O-ring is an example of this annular seal member.

[0008] According to the above technical means, the drainage plug device is of a release wire wiring type in the container.
The release wire can be connected to the operating part (more specifically, the push button case) by the same simple operation as above, and the ingress of water into the inner core from the concave part closes the concave part. Is prevented.

Further, it is preferable that the one end of the ring-shaped member is formed in a sharp shape which is in contact with or close to the flange of the outer tube.

[0010] According to the above-mentioned technical means, the outer tube is bitten into the flange in the pulling direction of the outer tube to enhance the pull-out strength of the outer tube.

Further, a release wire wiring type in the container,
Regardless of the external release wire wiring type, the washer member closes the space between the outer surface of the outer tube flange and the inner surface of the concave recess, and is fitted into the concave recess to fit the flange. Is more preferable (claim 4).

According to the above technical means, it is necessary to insert one end side of the release wire in which the washer member and the ring-shaped member are externally inserted sequentially from the open portion of the concave portion, so that the periphery of the outer tube flange and the concave portion are not inserted. A space (clearance) occurs between the inner surface of the part. Due to the space (clearance), if you push the push button by mistake while pressing on the lid by stepping on the closed state etc., the inner core that loses the escape place without pushing up the lid, It escapes and bends in the space (clearance) and causes buckling deformation at that portion. Escape areas that cause the buckling deformation are eliminated by a bottomed cylindrical washer member that closes the space (clearance) between the flange portion of the outer tube and the inner surface of the concave portion. that time,
A compressive force acts on the inner core.If the inner core is made of a coil made of metal, the inner core responds by compression.If the inner core is incompressible, the outer tube has an elastic Respond by distraction.

[0013] Further, in the drain plug device for opening and closing the drain plug by a pushing operation of an operating unit connected via a release wire to a drain plug provided on a container such as a bathtub, a sink, a basin or the like, In the push button case, the one end side of the release wire is inserted into a concave portion recessed from the side opposite to the push button side, and the inner core protruding from the release wire can be pushed by the push button, and the outer in the release wire A flange formed at one end of the tube abuts against a washer member applied to the bottom of the recessed portion, and a spring receiving member is externally inserted into the outer tube with the collar portion interposed between the washer member and the washer member. A spring receiving member and a stopper member that is inserted into the insertion hole formed in a side portion of the push button case in communication with the recessed portion, avoiding a release wire, and locked in the recessed portion. Is effective even if the interposed compressed elastic-machine over the (claim 5).

According to the above technical means, the washer member inserted from the concave recess opening portion is brought into contact with the bottom of the concave recess formed in the push button case, and the spring receiving member and the compression spring are moved. One end of the release wire is inserted through the recessed portion opening portion with the outer fitting inserted, and then inserted into the insertion hole opened in the side portion of the push button case and locked in the recessed portion. A stop member supports an end of the compression ram opposite to the flange. As a result, the flange portion at one end of the outer tube of the release wire is supported so as not to come off by the stopper member and the spring receiving member receiving the elastic force of the compression spring, and the inner core protruding from the outer tube is vertically moved by the push button case. Pushing can be performed by the axis of the push button that is movably inserted. Therefore, one end of the release wire, in which the washer member, the spring receiving member, and the compression spring are externally inserted, is sequentially inserted from the opening of the concave portion, and the stop member is inserted from the side to operate the release wire by a simple operation. Part (in detail, push button case)
The connection work to is completed. Also, if the push button is erroneously pushed while the stopper is being pressed, such as by stepping on the stopper, the inner tube is elastically deformed by the deformation of the inner core, which loses the escape space without pushing the stopper up. High elongational stress occurs. At that time, the compression ram is compressed to make the ends of the outer tube close to each other, so that the outer tube secures a relief area due to the compression of the inner core,
Prevents buckling of the inner core.

The drainage plug device is of a body release wiring type in which an operation portion is provided on an inner wall portion of the body, and the recessed portion and the outer tube are provided between the stopper and the compression ram. In the case where an annular seal member that closes the gap is interposed, it is preferable to prevent water from entering the inner core from the concave portion by the annular seal member that closes the concave portion as described above. (Claim 6).

[0016] In the case of a release wire type in which the operation unit is provided on the inner wall of the container, a push button case is mounted on a base plate provided on the inner wall of the container, and the insertion hole is opposed to the base plate. When the hole is opened, the stop member is hidden by the base plate, so that the design is safer for a bather.

[0017] Further, in the drain plug device of the release wire wiring type in the container, the drain plug is provided with a bottomed cylindrical guide portion provided at the mouth of the drain port, and is vertically suspended from the plug lid and vertically attached to the guide portion. A movable inner hollow elevating body guided, a support shaft having one end inserted into the elevating body from the bottom of the elevating body and the other end locked to the bottom of the guide portion, and penetrating the stopper. The inner core at the other end of the release wire located in the elevating body, and the other end of the inner core is formed on the supporting shaft by advancing the inner core provided between the support shaft and the elevating body by a pushing operation of the operation unit. A thrust lock mechanism that lifts and locks the stopper lid together with the elevating body against the bottom of the recessed part, unlocks the stopper, and unlocks and closes the stopper when the next inner core advances. From the inner core toward the elevating body A guide cylinder is vertically suspended, the guide cylinder is configured to be loosely fitted or slidably engaged with the recess of the support shaft through a slight clearance, and the length of the vertically extending guide cylinder is set in the unlocked state. Is also effective when the length is set in the concave portion (claim 8).

According to the above technical means, the push button is pushed to move the inner core forward so that the other end of the inner core abuts against the bottom of the recess formed on the support shaft to lift the stopper lid together with the elevating body. To lock the thrust lock mechanism and open it,
The thrust lock mechanism is unlocked and closed by the advance of the inner core by the pushing operation of the next push button. When the push button is pushed from the open state and the lock is released at the stage where the lock is released, the push button is pressed down and accidentally stepped on, etc. Escape is prevented by the guide tube, and buckling deformation of the inner core is prevented. Although there is no buckling deformation, a compressive force acts on the inner core.If the inner core is a coil made of metal, it responds by its own compression, and if the inner core is incompressible, It is the same as described above that the outer tube is elastically distracted. The condition in which the pressing force acts on the stopper by pressing the push button from the opened state and releasing the lock by pressing the push button at the stage where the lock is released, for example, is that the push button acts on the stopper. The conditions under which the load from both the lid side is applied are, for example, in a bathtub, when the water is supplied after cleaning, the push button is pushed to release the lock, and then the lid is slid and the push button is pushed and the lid is pushed. Occurs when the user steps on the button or when the interaction between the pushing operation of the push button by hand and the human body load on the stopper is performed almost simultaneously while the child is playing in the tank.

The locking recess 28 is locked to the support shaft 42 so that the support shaft 42 cannot move up and down. In the present embodiment, at least the lower end portion of the support shaft 42 is cut so as to be bisected in the axial direction so as to have some elasticity.

The operation of the drain plug 2 configured as described above will be described step by step. The state shown in FIG. 2 is a closed state. In this closed state, the upper and lower engaging teeth 521a, 521a of the rotating ring 521 are located in the upper end region of the groove 32 '. When the push button 31 is pushed from FIG. 2, that is, when the push button 31 is pushed from FIG. 6, the inner core 13 moves forward and pushes the support shaft 42. The inner core 13 that has lost its place because it is locked to be unable to move up and down raises the elevating body 32. In detail, the lower engaging tooth portion 521a of the rotating ring 521 is guided by the groove 32 'while compressing the spring 524, and the serrated tooth portion 52 of the fixed tooth 523 is formed.
7a comes into contact with the lower engaging tooth portion 521a (FIG. 7).
The elevating body 32 ascends until it moves along the slope of the saw-tooth part 523a as shown in (a) (the direction indicated by the arrow indicates the vertical movement of the elevating body 32 and the rotation direction of the rotating ring 521). The same applies to the following (b), (c), and (d).) When the push operation of the push button 32 is stopped,
As shown in FIG. 7B, the upper engaging tooth portion 521a of the rotating ring 521 is engaged with the serrated tooth portion 522a of the engaging tooth 522 which is lowered by receiving the urging force of the spring 524. Is opened (opened) while being spaced upward from the drain port 101 (FIG. 9). When the plug is opened, the layout is such that at least the tip of the guide tube 221g of the inner core 13 is located in the concave portion 421 of the support shaft 42. When the open state is changed to the closed state again, the push button 31 is pushed and pushed, and the lifting body 32 is pressed against the urging force of the spring 524.
Is raised once, and the serrated tooth portion 523a of the fixed tooth 523 is raised.
The lower engaging tooth portion 521a is brought into contact with the rotating ring 521, and the lower engaging tooth portion 521a is moved along the slope of the saw tooth portion 521a (FIG. 7 (c)). When the push operation of the push button 31 is stopped, the spring 5

It is led to 2 '(FIG. 7 (d)), and the elevating body 32 is lowered to the above-mentioned FIG. 2 and closed (closed).

Therefore, in the drainage plug device having such a configuration, the washer members 4, 4, and 4 can be inserted without performing the screwing operation using a special tool such as pliers.
One end of the release wire 3 can be connected to the operation unit 1 without externally exposing the metal member by inserting the ring-shaped member 5 and the seal member 6 into the release wire 3 and inserting the stopper member 7. . In addition, at the time of opening, since the layout is such that at least the tip of the guide tube 221g of the inner core 13 is located in the recess 421 of the support shaft 42, the push button 31 is pushed from the opened state to lock. Even if an accident such as stepping on the lid 22 by accidentally pushing the push button 31 is left at the stage of release, even if an accident such as stepping on the stopper 22 occurs, the elevating body 3 of the inner core 13 is guided by the guide cylinder 221g.
2 is prevented from escaping into the internal space (see FIG. 9).

Next, a second embodiment shown in FIG. 10 will be described. In this embodiment, the upper washer member 4 is provided with an outer peripheral surface of a flange 231 of the outer tube 23 and an inner surface of a concave portion 211. Since it is the same as the first embodiment except that it has a run-out preventing cylindrical portion 14 formed in a cylindrical shape with a bottom for closing the space (clearance) S, the same reference numerals are used to describe the same. Is omitted.

In the first embodiment described above, it is necessary to insert one end of the release wire 3 into which the upper and lower washer members 4 and 4 and the ring-shaped member 5 are inserted sequentially from the open portion of the concave portion 211. , A space (clearance) S between the periphery of the flange portion 231 of the outer tube 23 and the inner surface of the concave portion 211.
(See FIGS. 1 and 8). When the pressing force is applied to the stopper lid 22 by stepping on the stopper state or the like, the push button 31 is pressed.
If the user pushes the inner core 13 by mistake, the inner core 13 losing the escape space escapes and bends in the space S and buckles at that portion. The relief structure that causes the buckling deformation is eliminated by the run-out preventing tubular portion 14 that closes the space S between the flange portion 231 of the outer tube 23 and the inner surface of the concave portion 211. The cylindrical portion 14 is formed to have a diameter such that it can be just fitted when inserted into the concave portion 211 connecting one end of the release wire 3 to the operation portion 1. The order of attaching one end of the release wire 3 to the push button case 21 is the same as that of the first embodiment, and thus the description is omitted.

Next, a third embodiment shown in FIGS. 11 and 12 will be described. In this embodiment, instead of omitting the ring-shaped member, the washer member 4 having the cylindrical portion 14 is used. And a spring receiving member 4 ′ that is fitted to the outer tube 23 with the flange portion 231 of the outer tube 23 interposed therebetween, and the spring receiving member 4 ′ and the washer member 4 immediately above the annular seal member 7 are provided. It has a structure in which a compression elastic machine B is interposed therebetween. The spring receiving member 4 'and the washer member 4 immediately above the annular seal member 6;
Are both flat washers. The compression ram B is interposed between the spring receiving member 4 ′ and the annular seal member 6 on the stopper member 7.

In this embodiment, as shown in FIG. 11, the outer tube 231 is in elastic contact with the concave portion 211 indirectly via the washer member 4 due to the resilience of the compression spring B in the normal state. . When the push button 31 is erroneously pushed in a state where a pressing force is applied to the stopper lid 22 by, for example, stepping on the stopper state, the inner core 1 is pressed.
3 generates a compressive force, but the flange 2 of the outer tube 23
31 descends so that the end portions approach each other so as to compress the compression ram B via the spring receiving member 4 ′ (see FIG. 12), and the outer tube 23 creates a relief for the inner core 13. Buckling deformation of the inner core 13 can be prevented.

The present invention has been described in detail for a drain plug device of a release wire wiring type in a container.
Reference numeral 4 includes an extracorporeal release wire wiring type drain plug device. That is, the operation unit is usually attached to an upper edge surface of a bathtub or an upper edge surface of a ball portion side in a wash basin, in a drain plug device of the extracorporeal release wiring type. In detail, the operation part projects a mounting flange from a cylindrical push button case, and mounts the mounting flange in an upper edge surface or a concave portion provided on the upper edge surface in a housed state, and the push button is provided. A push button is attached to the end of a shaft that is vertically movably inserted into the case, while a drain plug is connected to a drain port member provided at a drain port opened at the bottom of the bathtub by an operation unit (details). Then push the push button) to raise the spindle with the advance of the inner core, lift the stopper, lock and open it, release the lock with the next advance of the inner core, and lower the stopper. It has a well-known structure including a mechanical box having a built-in thrust lock mechanism for closing. One end of the release wire is connected to the operation unit with the same configuration as in the first, second, and third embodiments, and the other end of the release wire is connected to the bottom of the mechanical box by the well-known structure. Only the inner core is connected so that the support shaft located in the radio box can be moved up and down. By doing so, even if the drain plug device is of the extracorporeal release wiring type, there is no need to screw the joint fitting with retightening at all, and the release to the operating section (specifically, the push button case) is performed. It is possible to construct a drain plug device whose wire assembling work is very simple,
Buckling deformation of the inner core due to the same reason as described above can be prevented. Further, in the case of the drainage plug device of the extracorporeal release wiring type, the annular sealing member is not required. In this case, a structure is employed in which the lower end of the ring-shaped member 5 and the lower end of the compression ram B are directly supported by the washer member 4 on the stopper member 7 or the stopper member 7.

[0051]

As described above, according to the present invention, the washer member inserted from the opening of the concave recess is brought into contact with the bottom of the concave recess formed in the push button case, and then the ring-shaped member is removed. By inserting one end of the release wire having a fitting shape from the opening of the recessed portion, and finally inserting and locking the stopper member from the insertion hole opened in the side portion of the push button case, the release wire is released. The connection work to the operation unit (specifically, the push button case) is completed. Therefore, the work of screwing the joint fittings together with retightening as in the related art is not required at all, and the work of assembling the release wire to the operation unit (specifically, the push button case) can be performed very easily. In addition, since a metal member such as a joint fitting is not exposed from the lower end of the push button case as in the related art, the exposed metal fitting such as a drain plug device of a type in which a release wire is wired in a bathtub is used. The bather is safe without injury.

In the case where an annular seal member is interposed between the stopper member and the ring-shaped member to close the recess between the concave portion and the outer tube, a release wire wiring type in the container is used. In the drain cock device, even if a part of the operation part is immersed, water does not enter the release wire through the inner core from the recessed part, does not impair the sliding property of the inner core, and avoids malfunction. can do.

Further, in a drain plug device of a release wire wiring type in a container, in particular, in a ring-shaped member for preventing the outer tube from coming off, an end which comes into contact with or approaches a flange portion of the outer tube has a sharp shape. When,
For example, even if a hand or finger touches the release wire accidentally during use (during bathing, using a basin or sink) and a tensile force is applied, the sharp end bites into the flange of the outer tube. This is effective in more reliably preventing the dropout.

In the case where the washer member has a bottomed cylindrical shape for preventing run-out which blocks the space between the outer surface of the flange portion of the outer tube and the inner surface of the concave portion, the washer is stepped on in a closed state. Even in the event of an accidental push operation of the push button in a state where a pressing force is being applied to the stopper lid, the inner core can be prevented from being buckled and deformed without an escape area.

In the operation section, the flange formed at one end of the outer tube of the release wire is brought into contact with a washer member applied to the bottom of the concave portion, and the outer portion is sandwiched between the washer member and the flange. A spring receiving member externally inserted into the tube and an insertion hole communicating with the concave portion and inserted into a side portion of the push button case are inserted around the release wire to avoid the release wire and locked in the concave portion. In the configuration in which the compression ram is interposed between the stopper member and the stopper, the push button is erroneously pushed in a state in which pressing force is applied to the stopper by, for example, stepping on the stopper in a closed state as described above. When an accident occurs, the compression ram is compressed to create a space for the inner core to escape by bringing the ends of the outer tube closer together, so that the inner tube does not burden the outer tube. It can be prevented A of buckling, also prevented as much as possible to apply a repulsive force due to elastic deformation of the outer tube to the inner cable, is also friendly design for the inner wire.

Also, in the case of a drain plug device of a release wire wiring type in a container, a push button case is attached to a base plate provided on an inner wall portion of the container, and the insertion hole is opened to face the base plate. Since even the stop member is hidden by the base plate and is not exposed to the inside of the container, safety for a bather can be further improved.

Further, in the case of a release plug device of a release wire wiring type in a container, the push button is pushed to move the inner core forward so that the other end of the inner core abuts against the bottom of the recess formed on the support shaft to move up and down. The thrust lock mechanism is lifted up together with the body to lock the thrust lock mechanism and open, and the thrust lock mechanism is unlocked and closed by advancement of the inner core by the next push button push operation, For example, in a bath tub, when the water is supplied after cleaning, push the push button to release the lock and release the lock, then slide and push the lid with the foot while pressing the push button, or a child is playing in the tub Even if the push button is pressed by hand and the human body load on the lid is interacted at the same time during the operation and an accident occurs in which the pressing force acts on the inner core, the inner core escapes to the outside. Tube Blocking to grant safety to prevent buckling.

In addition, since the guide tube of the inner core vertically extending from the stopper or the lifting / lowering body toward the lifting / lowering body is configured to be loosely fitted or slid into the concave portion formed in the support shaft, it is necessary to open the guide tube when opening. Also, when the stopper is closed, the lifting / lowering body does not stick around the insertion portion of the support shaft and exhibits excellent straightness, and there is also an accident in which the meshing relationship of the teeth constituting the thrust lock mechanism becomes poor and it runs idle. It can be prevented beforehand.
