Description

[Detailed description of the invention] (Industrial application field) This invention relates to the improvement of drainage devices in washbasins, bathtubs, etc., and in particular, the main body of the valve fitted in the drainage passage of the drainage equipment for opening and closing the passage. This is an improved structure of the opening/closing mechanism compared to the previous one, and is used in the field of manufacturing technology industry for this type of equipment.

(Prior Art) In general, when a drainage device for a washbasin, bathtub, etc. is used to store water in the sink, etc., the drain passage of the drain plug main body is blocked by the valve, and
It is well known that when draining water, the valve is operated to open the passage.

The valve opening/closing mechanism is such that the valve and the operating button are linked by a linking means, and by pushing the operating button, the valve is pushed up and opened, and conversely, by pulling the operating button, the valve is pulled down. It was configured to be in a closed state.

In addition, instead of the above-mentioned drainage device, although it is not yet known, there is a drainage device that was previously applied for by the applicant of the present invention, which requires a valve body for opening and closing the drain port and the valve body in the drainage passage. a push-up lever for pushing up to a height, and a plunger linked to the push-up lever is disposed on the outside of the drain passage with a spring biased so that the push-up lever moves back;
Further, the tip of an operating wire having a push button at its base end is attached to the plunger, and a locking pin is projected outward from the plunger, and the locking pin is locked to push the push-up lever. A regulating body for regulating the backward movement is disposed close to the plunger, and the regulating body further includes a locking portion that locks the locking pin by pushing the plunger in a direction in which the push-up lever is pushed up; There is a drainage device for a washstand or the like that includes a release part that releases the locked state by further pushing the plunger in the same direction. (Jitsugan No. 62-175651).

(Problems to be Solved by the Invention) However, this conventional technology has the following problems. That is, in the former case, the opening/closing operation of the valve requires repeating different operations of pressing down and pulling up the operating button, which may cause operational errors. In addition, since this pull-up operation is performed after firmly grasping the operation button with your hand, it is more troublesome to operate than the push-down operation of simply pressing down on the operation button from above, and is especially difficult for children and children who are weak. This was a nuisance for elderly people, and the buttons were slippery when they tried to hold them with soapy hands, causing valves to open and close incorrectly.

In the latter case, the above-mentioned drawbacks can be solved and the convenience of use can be improved, but the structure of the plunger and regulating body linked to the push-up lever is too complicated, resulting in high cost. There is a problem that it is easy to cause failure.

The present invention was developed with the aim of solving the above problems, and its purpose is to enable the valve to be opened and closed simply by pressing a push button, and to prevent malfunctions. It is an object of the present invention to provide a drainage device for a washstand, bathtub, etc., which also allows easy maintenance and inspection of essential parts.

(Means for Solving the Problems) As a means for solving the above problems, the present invention includes a removable valve body for opening and closing the drain port in the drainage passage, and a pusher for pushing the valve body to a required height. A lifting lever is provided, an operating mechanism for the lifting lever is provided outside the drainage passage, and a push button is provided on the base end side, and the push button is returned to the same position by a returning spring. A drainage device for a washbasin, etc., which is configured such that the tip of an operating wire biased in this manner faces the operating mechanism, and the operating mechanism is actuated by the tip of the operating wire by operating a push button. The mechanism is
An engagement/disengagement regulating body provided around the inner wall of the cannula, an engagement/disengagement actuating body provided inside the proximal end of the cannula so as to be able to move forward and backward, and the above-mentioned engagement/disengagement regulating body loosely fitted into the cannula on the front side of the engagement/disengagement actuating body. A locking/detachable element that moves forward and backward when engaging and disengaging from the body, a connecting actuating body that can move forward and backward, the proximal end of which is inserted into the cannula and the other protruding end connected to the operation member of the push-up lever; The washbasin is constructed of a return spring that is biased to retreat toward the end and is installed in the cannula, and the tip of the operating wire is arranged on the back of the engaging/disengaging body of this operating mechanism. We developed and adopted drainage devices for tables, bathtubs, etc.

(Function) When the push button of a drainage device for a washstand, bathtub, etc. configured as described above is pushed, the operating wire moves forward and its tip moves the engaging/disengaging body of the push-up lever's operating mechanism forward. Push the locking element, which had been pushed into the inside of the locking/unlocking regulating body by the spring pressure of the returning spring, from the inside, and compress the returning spring from the position shown in A to the position shown in B in Figure 6. In this state, the engaging/disengaging member is moved forward together with the engaging/disengaging body. Therefore, the connecting actuating body also moves forward and rotates the push-up lever as described later to move the valve body upward, but at this time,
The state of contact between the teeth formed on the upper periphery of the engagement and disengagement actuating body and the wing pieces formed on the circumferential surface of the engagement and disengagement element due to the regulating action of the plurality of protrusions of the engagement and disengagement regulating body is shown in the same figure. The state shown in A changes to the state shown in B, and the locking element is slightly rotated. Next, when the push button is released from the hand, the engagement/disengagement actuating body becomes free, and due to the elastic action of the returning spring, the tip of the wing piece of the engagement/detachment member moves to the engagement/disengagement regulating body as shown in C in the same figure. The locking member is press-fitted into the valley at the upper end of the protrusion and is prevented from retreating, so that the valve body is maintained in an upwardly moved state and the valve is maintained in an open state.

Next, when the push button, which has been returned to its original position by the action of the return spring on the push button side, is pushed in again, the valley of the toothed part on the upper periphery of the engagement/disengagement actuator is The tips of the circumferential blades of the locking element are press-fitted with slight rotation. Therefore, when the push button is released in this state, the tip of the circumferential protrusion of the locking element slides down into the longitudinal groove of the locking/disengaging regulating body, and the locking element returns as shown in E in the figure. Since it moves backward along the longitudinal groove by the spring pressure, the connecting actuating body also moves backward, and the push-up lever is rotated in the opposite direction to lower the valve body by its own weight, thereby closing the valve.

(Embodiment) Next, the present invention will be explained based on embodiment diagrams. Fig. 1 shows a drainage device 1 according to the present invention in a wash basin A.

An engaging member 8 is fixed.

A drainage flow regulating member 9 is fixed to the center of the valve body 3, and serves as a guide and a support member when the valve body 3 is inserted into the passage 2a. 9 and the valve portion 7 in a slidable manner.

The push-up lever 5 engages freely and perpendicularly with a freely engaging member 8 fixed to the lower end of the valve body, and moves up and down with the pivot shaft 10 of the lever 5 as a fulcrum. It rotates. Further, a rotation operating lever 10 ₁ is fixed to the rotation shaft 10 . Further, the distal end portion 5a of the push-up lever fitted into the drain passage 2a is provided so as to protrude below a freely engaging member 8 fixed to the lower end portion of the valve body 3. As shown in FIG. 3, the lower surface of the universally engaging member 8 is formed with a bifurcated engaging curved surface 8a that freely engages with the tip end 5a of the push-up lever. Therefore, when the valve body 3 is fitted into the drain passage 2a of the drain plug body 2,
The valve body 3 rotates the tip end 5a of the push-up lever 5 downward by its own weight, and the valve part 7
comes into close contact with the opening periphery of the passage 2a, that is, the periphery of the drain port _A1 , and the valve is closed. Conversely, when the tip portion 5a of the push-up lever 5 is rotated upward by the operating mechanism 6, the tip portion 5a reliably abuts the engagement curved surface 8a, so that the valve body 3 is rotated upward. Push up to open the valve.

Further, in the above embodiment diagram, the valve body 3 includes a shaft fitting 3a having a required weight, a valve fitting 3b fixed to the upper end of the shaft fitting 3a, a lower end portion of the shaft fitting 3a, a central portion thereof, and the valve fitting 3b.

The operating mechanism includes a locking/disengaging body 14, a locking element 15, and a buffer body 1 which are internally movable from the proximal end in a cannula 13 of a one-way type actuating mechanism B to be described later.
6. A mechanism is adopted in which the valve is opened and closed by pressing the connecting lever 17 and the returning spring 18 by remote control using a wire.

The pressing member 20 at the tip of the operating wire 19 is disposed facing the end surface of the proximal end of the engaging/disengaging body 14, and the pressure receiving member 21 at the proximal end of the operating wire 19 is located opposite to the end surface of the engaging/disengaging body 14. The push button 2 is provided opposite to the push rod 23 of 22, and the push button 2 is
Spring biased in two directions. 25 is push button 22
It is a support member that supports the press rod 23 and the pressure receiving member 21, and is attached to the washstand A with bolts and nuts.
A push button 22 is fitted onto the upper end of the button. Therefore, when the push button 22 is pressed against the spring force of the returning spring 24, the pressing member 20 presses each member installed in the sleeve 13 through the operation wire 19, and conversely, the pressing force is increased. When the button 22 is removed, the push button 22 returns to its original position due to the force of the spring 24. 26 is a flexible tube that protects the wire.

Next, the one-way push-up lever operating mechanism B will be explained. As shown in FIGS. The regulating body 27, the engagement/disengagement actuating body 14 that is movably provided inside the proximal end of the sleeve 13, and the above-mentioned engagement/disengagement regulating body 27 that is loosely fitted into the cannula 13 on the front side of the engagement/disengagement body 14. The engaging/detachable element 15 that moves forward and backward during engagement and disengagement, the buffer body 16 loosely fitted to the front side of the engaging/detachable element 15, and the proximal end 17a are inserted into the cannula 13 while the hook-shaped protruding other end 17b is pushed up. A connecting actuating body 17 that can move forward and backward, connected to the actuating member consisting of the rotation operating lever ₁₀₁ of the lever 5, and a returning member that is biased to move the connecting actuating body 17 backward toward the proximal end and is installed in the cannula. A spring 18 is disposed opposite to the back of the engaging/disengaging body 14 of the operating mechanism B, with the tip of an operating wire 19 facing the back.

The engagement/disengagement regulating body 27 has three serrated portions 27c formed by connecting an engagement valley portion 27a and a slide surface 27b at equal intervals around the upper end, and each serrated portion 27c. It is composed of three guide grooves 27d formed in between.

Further, the engaging/disengaging body 14 has a protruding base rod 14a.
Six serrated portions 14d in which protrusions 14b and engaging valley portions 14c are alternately formed are provided at the tip of the serrated portion 14d, and
An engagement hole (not shown) is provided in the center of the upper surface, and vertically elongated wing pieces 14e are provided on the lower outer peripheral side of every other three sawtoothed portions 14d among the six sawtoothed portions 14d.
It is constructed by protruding.

Further, the locking/detachable element 15 is connected to the locking/detachable body 1.
It has a rod part 15a that is removably inserted into the engagement hole of No. 4, and three vertically long wing pieces 15b on the top thereof
are provided protrudingly at equal intervals, and the lower ends of the wing pieces 15b form engagement edges 15c.

Furthermore, the connection operating body 17 is connected to the cannula 13.
An enlarged base portion 17a is provided on the proximal end side of the rod portion inserted into the sleeve, and a distal end portion 1 protrudes to the outside of the cannula 13.
A hook 17c is formed on the 7b side, and this hook 17c is connected to the rotation operation lever 10.
1 is pivotally connected to the free end of ₁ .

Next, the valve opening/closing operation by the one-way operating mechanism B configured as described above is performed as shown in FIG.
The explanation will be based on C, D, and E.

First, as shown in FIG. 6A, each wing piece 14e of the engagement/disengagement actuating body 14 of the actuation mechanism B and each wing segment 15b of the engagement/detachment element 15 are inserted into each guide groove 27d of the engagement/disengagement regulating body 27.
When the engaging/disengaging body 14 and the engaging/disengaging element 15 are placed inside the engaging/disengaging regulating body 27,
The rod portion 15a of the locking element 15 is inserted into an engagement hole (not shown) in the center of the upper surface of the locking/disengaging body 14, and the protrusion 14b of the serrated portion 14d of the locking/disengaging body 14 and the lever 15 The lower end engaging edges 15c of the wing pieces 15b are brought into contact as shown in A in the figure. Next, in the above state, when the push button 22 is pushed in as shown in FIG. The locking element 15, the buffer body 16, and the connection actuation body 17 are pushed together, and the hook portion 17c of the connection actuation body 17 rotates the rotation operation lever ₁₀₁ as shown in FIGS. 1 and 2. ,
The push-up lever 5 is rotated upward via the rotation shaft 10, and the push-up lever 5 moves the valve body 3 upward to push up the valve portion 7 and open the drain port _A1 . At this time,
Each wing piece 15b of the engagement/detachment element 15 has been pulled out from each guide groove 27d of the engagement/disengagement regulating body 27, and the engagement/detachment element 15
is released from the regulating body 27, so the locking element 1
The lower end engagement edge 15c of each wing piece 15b of No. 5 slides into the engagement trough 14c of the engagement/disengagement body 14 as shown by the arrow, so that the engagement/disengagement element 15 rotates slightly in the direction of the arrow.

Next, when the push button 22 is released and the pushing force of the operating wire 19 against the engagement/disengagement body 14 is released, the engagement between the engagement/disengagement body 14 and the engagement element 15 is released, and therefore the returning spring 18 Due to the elastic force, the connection actuating body 17, the buffer body 16, and the locking element 15 move back slightly as shown in C of FIG.
Serrated portion 27c formed at the upper end of the engagement/disengagement regulating body 27
Since the valve body 3 engages with the engagement trough portion 27a of the valve body 3 and stops its backward movement, at this point, even though the valve body 3 may be slightly lowered due to its own weight, the drain port _A1 is still opened.

In addition, in order to close the drain port _A1 with the valve from the above state, push the push button 22 again as shown in D and E of FIG. After pushing the operating body 14, the push button 22 may be released. That is, when the engaging/disengaging body 14 moves forward as shown in FIG. 6D,
At the same time, the protrusion 14b of the serrated portion 14d provided at the tip abuts the lower end engagement edge 15c of the wing piece 15b of the engagement element 15, and at the same time, the engagement edge 15c
Each serrated portion slides into the engagement trough 14c of the serrated portion 14d of No. 4 and rotates the locking element 15 slightly in the direction of the arrow to form each wing piece 15b at the upper end of the engagement regulating body 27. 27c sliding surface 27
Place it facing the top of b. When the push button 22 is released, the retractor 15 moves back due to the elastic force of the returning spring 18, and as shown in E of FIG. The wing piece 15b of the locking element 15 comes into contact with the sliding surface 27b of the locking/disengaging regulating body 27, and passes through the sliding surface 27b.
is guided and inserted into the guide groove 27d of the engagement/disengagement regulating body 27, and all the members housed in the cannula 13 are moved back and forth by the elastic force of the spring 18 to the position shown at A in FIG. In this way, as the connection operating body 17 retreats, the rotation operation lever 10 ₁ also rotates again, so the push-up lever 5 moves downward, and the valve body 3 descends due to its own weight, and the drain port A ₁ is blocked by the valve part 7. will be done.

As described above, according to the above embodiment, the drain port _A1 of the drain device can be opened and closed by the valve portion 7 only by pushing the push button 22, that is, by the so-called "one-way system". It goes without saying that the internal structure of the operating mechanism B is not limited to the above embodiment, and that various design changes are possible.

Although not shown, a structure in which the perforated plates 4 are arranged in two stages, upper and lower, may be adopted, in which case the collection effect of the perforated plates can be further improved.

(Effect of the invention) Since the present invention is constructed as described above and operates as described above, as a result, the valve can be opened and closed simply by pressing down the push button, thereby preventing the occurrence of erroneous operation. This valve has the advantage that it is very easy to use even for children and the elderly, and it also has the advantage that the valve can be opened and closed extremely easily since there is no need to pull up the push button at all.

In addition, the so-called one-way operating mechanism that brings about the above effects is configured using a push-button locking/unlocking mechanism of a ballpoint pen, so it is simple to configure, has few failures, and can be used repeatedly over a long period of time. , since the installation space for the actuation mechanism is sufficient as long as the reciprocating movement of the inner member of the cannula is ensured,
The installation space is the same as that of conventional drainage equipment, and construction costs can be kept low.Furthermore, since the operating mechanism is located outside the drainage passage,
A sufficient drainage channel can be secured, allowing smooth drainage, and maintenance and inspection can be easily carried out.The valve body can also be attached and detached, making cleaning and maintenance inspection of the valve body and the inside of the drainage passage easy. It has the effect of being easy to perform.
