Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for operating a drain plug provided at the bottom of a bathtub, for example, by remotely operating the drain plug with an operation button provided on the rim surface of the bathtub.

[0002]

[Prior Art]

 It is known that a drain plug provided at the bottom of a bathtub is one that is opened by connecting it to a ball chain and pulling it up. In recent years, instead of this, a mechanism that incorporates a drain tap operation mechanism outside the bathtub and that is remotely controlled by a push button or a rotatable handle provided on the rim surface of the bathtub has been widely used.

As such a remote-operated drain plug, for example, there is one described in Japanese Utility Model Laid-Open No. 2-109872. This has a structure in which a push button type operation unit is provided on the rim of the bathtub, and this operation unit is connected to the drain plug provided at the bottom of the bathtub via a wire.The drain button can be opened by pressing the operation button. It is the one. Then, in order to keep the drain plug open, the thrust lock mechanism can be installed on the drain plug side and the drain plug can be closed by pressing the operation button again.

Further, a thrust lock mechanism is provided on the operation portion side, and like the ballpoint pen knock mechanism, the drain button can be opened by pressing the operation button, and the drain button can be closed by pressing the operation button again. Some have been done.

[0007] In these remote-operated drain plugs, when the drain button is opened, when the operation button is pressed, it is locked in the pushed-in position, and when it is closed, the lock is released by pushing again. The operation button requires a stroke that allows the drain plug to be moved by a wire or other link mechanism, and can be incorporated in the housing of the hollow cylindrical operation part with its upper end exposed. Required by design.

[0006]

[Problems to be solved by the device]

 However, after pressing the operation button to open the drain plug, if for some reason there is a malfunction in the wire or link mechanism with the drain plug or damage to the thrust lock mechanism, pressing the operation button again May not return to the position. That is, the control button remains stuck in the housing and cannot be removed from the housing.

Since the operation button is formed by connecting a wire, a link, etc., if the operation button is left in the housing as described above, it will be difficult to confirm a defective part or a damaged part and replace parts. In particular, in order to pull out the operation button from the housing, not only the operation button but also the wire, the link, and the drain tap side member must be moved.Therefore, unreasonable force is applied to the member during this work. This will lead to new damage to the members.

As described above, in the drain plug that is a push button type and includes a mechanism for locking the plug in the open state, the operation button and the drain plug-side chain member connected to the operation button are integrally connected. The operation buttons cannot be removed due to defective operation or damage to the members, which makes inspection and disassembly work troublesome.

The problem to be solved in the present invention is to easily remove the operation button when the member is damaged in the remote control type drain plug, and to reduce the labor of the work.

[0010]

[Means for Solving the Problems]

 The present invention relates to a push-button type operation button incorporated in an operation section, a chain mechanism provided between the operation button and a drain plug provided at the bottom of a tank such as a bathtub, and the operation mechanism by pressing the operation button. A lock mechanism for restraining the plug of the drain plug when it is opened, and when the operation button is pressed, it surrounds the operation button and movably supports it. In the operating member structure, the operation button is depressed into the surrounding member, and the operation button is detachable from the chain mechanism and the surrounding member.

The operation button has a bowl shape with an open lower end, and has a mounting slit on its peripheral wall that extends upward from the lower end, a guide slit that extends in the circumferential direction from the upper end of this mounting slit, and a downward direction from the end of this guide slit. The restraint slit is cut open, the operating part is equipped with a sleeve that supports the operating button so that it can move in the axial direction, and the stopper has an outer dimension smaller than the slit width of each slit on the inner circumference of the sleeve. May be provided.

[0012]

[Action]

 When the push button type operation button of the operation unit is pressed, the chain mechanism is driven to open the drain plug, and the lock mechanism keeps the drain plug open, and the operation button is also restrained in the pushed position. The operation button can be attached to and detached from the surrounding member that supports it so that it can move in the operating direction, and the chain mechanism. The button can be removed from its surroundings. Therefore, by removing the operation button, which is one of the surface members of the operation section, it is possible to inspect and disassemble the chain mechanism and lock mechanism.

In addition, the operation button has a bowl shape, and a slit is formed in the peripheral wall such that the operation button extends from the bottom to the top, runs from the upper end in the circumferential direction, and extends from the end to the bottom, and moves the operation button in the operation direction. By providing a freely supporting sleeve on the operating portion and providing a stopper for inserting the sleeve into the slit, the sleeve can be easily removed from the operating portion by rotating the operating button.

The drain plug 2 has a structure in which a drain fitting 2a integrated with a drain cylinder 5a is incorporated in the bottom surface of the bathtub 1, and a plug 2b can be raised and lowered with respect to the drain fitting 2a. The plug body 2b is provided with a packing 2c, and a fitting 2d is protruded downward and a guide vane 2e having a cross-shaped cross section is connected to the periphery thereof. The mounting member 2d has a hollow cylindrical shape, and a spline 2f is formed on the inner periphery of the lower end of the mounting member 2d, and the spline 2f is engaged with the moving member 2g that is movable in the axial direction. Then, a coil spring 2h is incorporated between the moving body 2g and the plug 2b to urge the plug 2b and the moving body 2g away from each other.

The final stage link of the lever link mechanism 7 in the connector tube 5 is connected to the mover 2 g of the drain plug 2. The lever link mechanism 7 includes a driven link 7a in which one end faces the lower end of the guide tube 4, a fulcrum link 7b having an arched shape and seated on the inner wall of the connector tube 5, and two connectors. It has links 7c and 7d. Then, the connector link 7d at the final stage is connected to the moving element 2g by the screw 7e, and the moving operation of the moving element 2g can be performed by the combined movement of the two connector links 7c and 7d from the fulcrum link 7b.

FIG. 3 is a vertical cross-sectional view of the operation unit 3.

The operation unit 3 is provided with a thrust lock mechanism, which is employed in, for example, a ballpoint pen, inside a sleeve 3a which is fixed by penetrating the rim 1a of the bathtub 1. This thrust lock mechanism has the function of setting a member from the non-operating position to the operating position by pressing the button once to lock it, and then pressing the button again to return the operating position to the non-operating position.

In FIG. 3, a spindle guide 3b is provided inside the sleeve 3a for movably supporting the spindle 3c connected to the thrust lock mechanism and the link rod 6 coaxially. The spindle 3c is urged upward by the coil spring 3d, and when there is no downward pressure, the link rod 6 in the guide tube 4 is held in the pulled-up position.

A hollow cylindrical operation button 8 having an open lower end is vertically movably incorporated in the upper end of the sleeve 3a. FIG. 4 shows the details of the operation button 8, and FIG. 5 shows the outline of the built-in structure for the sleeve 3a.

The operation button 8 has a hollow cylindrical shape with an open lower end, and has an outer diameter capable of moving up and down coaxially in the sleeve 3a. Further, on the peripheral wall of the operation button 8, two slits 8a are provided so as to be point-symmetric with respect to the center thereof. As shown in FIG. 4, the slit 8a includes a mounting slit 8b that is raised from the lower edge, a guide slit 8c that extends circumferentially from the upper end of the mounting slit 8b, and a guide slit 8c that extends downward from the end of the guide slit 8c. Each of them has a shape defined by a restraining slit 8d that is cut in the vertical direction. The lower one edge of the guide slit 8c is formed as a surface that is gently inclined downward toward the restraining slit 8d.

On the other hand, on the inner circumference of the sleeve 3a, two stoppers 3e are provided at positions facing each other in the radial direction. The stopper 3e has an outer diameter that allows it to be inserted into the sleeve 8a of the operation handle 8.

As shown in FIG. 5, when the operation button 8 is inserted into the sleeve 3a by aligning the position of the mounting slit 8b with the stopper 3e, the stopper 3e follows the mounting slit 8b and enters. The operation button 8 can be incorporated into the sleeve 3a. As a result, the stopper 3e comes to be positioned at the upper end of the mounting slit 8b and at the one end side of the guide slit 8c. Next, when the operation button 8 is turned clockwise in FIG. 5, the guide slit 8c rotates while following the stationary stopper 3e, and the stopper 3e is positioned at the upper end of the restraining slit 8d.

In this way, when the posture of the operation button 8 is determined so that the stopper 3e is included in the restraining slit 8d, the restraining slit 8d is closed at both upper and lower ends thereof, so that the operating button 8 is stopped by the stopper 3e. The vertical stroke is restricted by.

As shown in FIG. 6, the thrust lock mechanism provided between the operation button 8 and the spindle 3c is a bushing 9 fixed in the spindle guide 3b, and is inserted in the bushing 9 to move coaxially. It is composed of a reduction rod 10 whose upper end abuts against the lower surface of the operation button 8 and a rotor 11 which is connected to the lower end of the reduction rod 10 and whose lower surface abuts against the upper end of the spindle 3c.

FIG. 7 is a detailed view of the bushing 9, in which (a) is a vertical cross-sectional view thereof and (b) is a horizontal cross-sectional view taken along the line AA of FIG. , (C) of the figure is a bottom view.

The bushing 9 is coaxially fixed in the spindle guide 3b, and a chamber 9a having a large inner diameter is provided at the lower end of the bushing 9. On the inner peripheral surface above the chamber 9a, two kinds of first grooves 9b and two second grooves 9c arranged radially are formed in the axial direction in threes, as shown in FIG. 7B. Then, a feed dog 9d having an uneven surface is provided downward on the wall of the upper end of the chamber 9a.

The feed dog 9d is formed at a total of three places from the first groove 9b adjacent to the second groove 9c to the front part of the next first groove 9b, and is a development view of the feed dog 9d in FIG. As shown in, there are a total of 6 steps in the circumferential direction.

9A and 9B show the details of the reduction rod 10. FIG. 9A is a vertical cross-sectional view thereof, and FIG. 9B is an enlarged bottom view thereof.

The pressing rod 10 has a hollow cylindrical shape with an open lower end, and the outer peripheral surface of the lower end has six protrusions slidably inserted into the first and second grooves 9 b and 9 c of the bushing 9. Forming a strip 10a. Then, the feed dog 10b having a total of six peaks is formed on the entire lower surface including the protrusions 10a.

FIG. 10 is a detailed view of the rotor 11, in which (a) is a front view, (b) is a plan view, and (c) is a bottom view.

The rotor 11 has a support shaft 11 a protruding from the upper end thereof, and the support shaft 11 a is incorporated into the lower end of the pressing rod 10 so as to be rotatable and movable in the axial direction. A hollow holding seat 11b is formed at the lower end of the support shaft 11a so as to cover the upper end of the spindle 3c to connect the spindle 3c, and three ridges 11c are provided around the holding seat 11b. These protrusions 11c have a shape that can be inserted into the first groove 9b of the bushing 9 and can slide in the first groove 9b.

Further, the rotor 11 is provided with a total of three teeth 11d on the upper surface of the holding seat 11b in the direction in which the protrusion 11c extends in the radial direction. These teeth 11d have a triangular tooth shape in which one surface of the upper end is inclined in the same direction as shown in (a) of FIG.

As shown in FIG. 3, the thrust lock mechanism constituted by the above elements is incorporated by inserting it into a bushing 9 in which a reduction rod having a rotor 11 integrated at the lower end is fixed in the spindle guide 3b. The upper end of the pressing rod 10 hits the lower surface of the operation button 8.

Here, when the operation button 8 is pressed, the pressing rod 10 is pressed down as shown in FIG. 11, and the spindle 3c is pressed downward by the rotor 11 at the lower end of the pressing rod 10. At this time, the protrusion 10a of the pressing rod 10 enters into the chamber 9a of the bushing 9 and makes a stroke so that the holding seat 11b of the rotor 11 is lowered to a position where it is accommodated in the chamber 9a. Then, when the operation button 8 is released thereafter, the spindle 3c is moved up by the coil spring 3d, and accordingly the rotor 11 and the pressing rod 10 are also moved upward.

As the rotor 11 rises, the teeth 11d provided on the upper surface of the holding seat 11b come into mesh with the feed teeth 9d of the bushing 9. On the other hand, when the rotor 11 is held by the bushing 9, the ridge 11c slides in the first groove 9b, so that the rotor 11 moves without rotation. During this movement, the teeth 11d are still meshed with the feed teeth 10b of the pressing rod 10, the rotor 11 does not change its posture, and the protrusion 11c has the first groove 9b as shown in FIG. Only when you get out of it can you rotate.

With such a structure, when the rotor 11 rises and its teeth 11d abut the feed dog 9d of the bushing 9, the feed of the bushing 9 is adjusted so that the inclination is different from the feed dog 10b of the pressing rod 10. By forming the tooth 9d, the tooth 11d rotates when meshing with the feed dog 9d. When the rotation angle is set to 60 degrees, the protrusion 11c of the rotor 11 is out of alignment with the first groove 9b, and the holding seat 11b is restrained by the lower end of the bushing 9 as shown in FIG. .. Therefore, the position of the spindle 3c pushed downward is locked at the position shown in the figure, and is held at the fixed position.

Further, when the operation button 8 is pressed from the state of FIG. 12, the state returns to the state of FIG. 11, and at this time, the teeth 11 d of the rotor 11 are brought into mesh with the feed teeth 10 b by the lowering of the pressing rod 10. Become. At this time, the rotor 11 rotates by 60 degrees due to the difference in shape and inclination of the feed dog 9d of the bushing 9 and the feed dog 10b of the pressing rod 10. Therefore, the protrusion 11c comes to be aligned with the first groove 9b of the bushing 9, and as a result, even if the operation button 8 is pressed once, the state shown in FIG. 3 is restored by the restoring force of the coil spring 3d.

As described above, by using the thrust lock mechanism, the spindle 3c can be moved down and up only by pushing the operation button 8.

In the above configuration, when the operation button 8 of the operation unit 3 is pressed, the spindle 3c descends and stops at the position locked by the thrust lock mechanism as described above. When the spindle 3c descends, the link rods 6 connected to the spindle 3c are also pushed downward, and the rollers 6a provided at these joints slide on the inner circumference of the guide tube 4 and roll.

As the link rod 6 descends, the weight 6e at the lower end thereof falls into the connector tube 5, thereby pushing down the driven link 7a of the lever link mechanism 7. Therefore, the fulcrum link 7b and the two connector links 7c and 7d push up the plug body 2b of the drainage plug 2 to open the drainage plug 2.

When the depressed operation button 8 is pushed again, the spindle 3c rises and the link rod 6 and the weight 6e at the lower end thereof are also pulled up, as described with reference to FIGS. As a result, there is no constraint on the driven link 7a, and the drain plug 2 is lowered by the weight of the plug 2b to close the flow path.

Here, when the drain plug 2 is opened, the operation button 8 is dropped into the sleeve 3a as shown in FIG. 11, and thereafter, the operation button 8 is held at the position of FIG. Then, when closing the drain plug 2, the operation button 8 is once pushed down from the state of FIG. At this time, if the movement of the link rod 6 or the thrust lock mechanism is improper, for example, the operation button 8 remains locked in the state shown in FIG.

On the other hand, the operation button 8 is rotated so that the stopper 3e in the sleeve 3a comes out of the restraining sleeve 8d and fits in the mounting sleeve 8b. This can be done by simply attaching an adhesive tape or the like to the upper end surface of the operation button 8 that has fallen into the sleeve 3a, and holding and turning the adhesive tape by hand. As a result, as shown in FIG. 12, the stopper 3e in the restraining sleeve 8d relatively moves in the guide slit 8c toward the mounting slit 8b by the rotation of the operation button 8. Then, as shown in FIG. 5, when the stopper 3e is located at a position aligned with the mounting slit 8b, the lower end of the mounting slit 8b is open. Therefore, if the operation button 8 is pulled up, it interferes with the stopper 8e. It can be pulled out from the sleeve 3a without any need.

As described above, the operation button 8 is not integrally connected to the spindle 3c by means such as a screw, but due to the positional relationship between the slit 8a and the stopper 3e, the pressing force is transmitted to the spindle 3c and the spindle 3c Can be separated. For this reason, even if the operation button 8 falls into the slit 3a when the member of the opening / closing mechanism of the drainage plug 2 is damaged or its movement is bad, the operation button 8 can be easily removed by the procedure described above. Can be removed. Therefore, the labor of the work prior to the inspection and disassembly of the inside of the operation unit 3 can be saved, and the work can be performed easily.

Although the drain plug of the bathtub has been described in the embodiment, it is needless to say that the operating structure of the present invention can be applied to various water baths such as a washbasin.

[0050]

[Effect of the device]

 In the present invention, the operation button of the operation unit can be easily pulled out by making it unrelated to the surrounding member around it and the chain member between it and the drain plug. Therefore, it is possible to easily inspect and disassemble the operating mechanism and the chain mechanism for driving the drain tap, and the burden on the operator at a narrow construction site such as a bathroom is reduced.

Further, by rotating the operation button in a bowl shape in the sleeve of the operation portion, it is possible to engage or disengage the slit on the peripheral wall of the operation button and the stopper on the sleeve side. It can be attached and detached without the need for and without damaging the members.
