Abstract

<P>PROBLEM TO BE SOLVED: To provide a drain plug device for a wash basin, a sink, etc., which prevents its plug cover from popping up from a drain port and waggling in the same, while enhancing the water cutoff performance of the drain plug device. <P>SOLUTION: According to the structure of the drain plug device, a support shaft 22 of the plug cover 12 is rockably and disengageably engaged with or rockably magnetized to an operating shaft 5 of a support portion S of a drain plug 2, and therefore the plug cover 12 is prevented from popping up from the drain port b or waggling in the same even if the verticality of the operating shaft 5 of the support portion S is not achieved. Thus the plug cover 12 can be fitted into the drain port b to cut off water without causing leakage, based on rocking operation of the support shaft 22 of the plug cover 12 with respect to the operating shaft 5. Then the plug cover 12 is drawn downward to make intimate contact with the drain port due to addition of a lowering force of the operating shaft 5, which contributes to improvement in cutoff performance of the plug cover. Further, cleaning of the interior of a drain port member 100 is carried out by removing the plug cover 12 together with the support shaft 22. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a drain plug device such as a wash basin and a sink, and more specifically, an operation shaft supported by the support portion of the drain plug is moved up and down by operation of the operation portion, and the stopper lid is driven to drain the water at the bottom of the water tank. The present invention relates to a drain plug device that opens and closes a mouth.

  Conventionally, this kind of basin, sink, and other drainage stopper devices have nuts attached to the drainage port member through packing at the bottom of the water tank, and a drainage plug support part is installed on the drainage port member. The operation shaft of the support portion is alternately raised and lowered, thereby repeatedly opening and closing the plug lid by pushing up the support shaft of the plug lid and closing the plug lid by lowering (for example, Patent Document 1 and Patent Document 2). reference).

By the way, the support part of the drain plug attached to the drain port member has a structure that guides the operating shaft so that it can move up and down, and a structure that has an opening and closing part that repeats locking and unlocking alternately. Actually, the verticality of the operating shaft does not appear accurately due to clearance, mounting error (locking error), and the like.
In particular, since the support portion of the drain plug is often installed at a lower level of the drain port member, when the support shaft of the plug lid is integrated with the operation shaft, the distance between the operation shaft and the plug lid is long. As a result of the vertical error being amplified and the inclination being increased, the water stoppage at the time of plugging is not satisfied and water leaks.
For this reason, as in Patent Documents 1 and 2, the support shaft of the plug lid is separated from the operating shaft of the support portion, and the plug lid is closed by its own weight.
However, if the support shaft of the plug lid is pushed up by an operating shaft that is separate from it, the plug lid may jump out of the drainage outlet by the moment when the operating shaft is pushed by the operation of the operation section, or the plug lid will dance. As a result, there is a problem that a collision noise is generated between the operating shaft and its supporting shaft, which makes the user uncomfortable.
Further, since the water is stopped only by the dead weight of the stopper lid, there is a problem that the water stop at the low water level is not reliable.
Japanese Patent Laid-Open No. 9-125485 JP 2001-342658 A

  The present invention has been made in view of the above-described conventional circumstances, and its intended process is to prevent the stopper lid from popping out from the drain outlet and dancing in the drain outlet while enhancing the water-stopping property.

The technical measures taken to solve the above problems are to connect drainage joints to drainage port members attached to the bottom of a water tank such as a wash basin, sink, etc. to form a drainage channel, and open and close the drainage port by operating the operation unit. In a drain plug device such as a wash basin or a sink in which the support portion of the drain plug is disposed in the drain channel, the support shaft of the plug lid can be swung with respect to the operation shaft of the support portion and can be artificially pulled. A drain plug device for a wash basin, a sink or the like, wherein the support shaft is detachably engaged with a locking force such that the support shaft is disengaged from the operating shaft by force (Claim 1).
And, a drainage joint is formed by connecting a drainage joint to a drainage port member attached to the bottom of the water tank such as a basin, a sink, etc., and the support part of the drainage plug that opens and closes the drainage port by operation of the operation part is connected to the drainage path. In a drain plug device such as a wash basin or a sink, it is also effective when the support shaft of the plug lid is magnetically attached to the operating shaft of the support portion so as to be able to swing (claim 2). .

According to the above means, the support shaft of the plug lid swings with respect to the operation shaft of the support portion, and the plug cover is fitted uniformly over the entire drainage port, regardless of whether or not the operation shaft and the support shaft are vertical. Close in a watertight manner.
In addition, at least the lowering force of the operating shaft pulls the stopper lid downward, thereby improving the water stoppage.
And, the plug lid is not allowed to dance or jump out without depending on the strength of the pushing force of the operating shaft by the operation of the operation unit.
In addition, the lid can be removed.

  Also, if the locking force and magnetizing force are set so that the support shaft is detached from the operating shaft by an artificial pulling force, the plug lid can be removed by grasping and pulling the plug lid in the opened state. (Claim 3).

  Furthermore, a drainage joint is formed by connecting a drainage joint to a drainage port member attached to the bottom of a water tank such as a basin, a sink, etc., and the support part of a drainage plug that opens and closes the drainage port by operating the operation part is arranged in the drainage channel. In a drain plug device such as a wash basin and a sink provided, a sleeve-like object having an elastic portion between slits provided in the axial direction in the lower half portion is provided on a support shaft of the stopper lid, and the sleeve-like object is provided in the sleeve-like object. The operating shaft of the support portion is inserted with a clearance, and the arc-shaped convex portion provided inwardly on the elastic portion is engaged with the arc-shaped concave portion having a shape matching the arc-shaped convex portion provided on the operating shaft of the support portion. A specific configuration in which the support shaft can be swung with respect to the operating shaft and can be engaged and disengaged can be given as an example (claim 4).

Since the present invention is configured as described above, it has the following advantages.
(Claims 1 and 2) Since the support shaft of the plug lid is swingably and detachably engaged with or magnetically attached to the operation shaft of the support portion, the vertical angle is set to the operation shaft of the support portion. Even if there is no leakage, the stopper lid can be prevented from jumping out and dancing in the outlet, and the stopper lid's support shaft swings with respect to its operating shaft without leaking the stopper lid to the outlet. Can fit to stop water.
In addition, the lowering force of the operating shaft is applied and the plug lid is pulled downward to bring it closer to the drain port, which contributes to the improvement of water stoppage. For example, when the lid and support shaft are molded with a lightweight synthetic resin material Even when the water storage is at a low water level, the water can be reliably stopped.
And since it does not jump out or dance, it is not stolen, and the inside of the drain port member can be cleaned by removing the stopper lid together with its supporting shaft.
(Claim 3) If the locking force and the magnetizing force of the stopper cover support shaft with respect to the support portion operation shaft are set to such an extent that the support shaft is detached from the operation shaft by an artificial pulling force, use a tool. Without removing the stopper lid together with its supporting shaft.

  Hereinafter, an embodiment of a drain plug device of the present invention basin, sink, etc. will be described with reference to FIGS. 1 to 7. FIG. 1 to FIG. 3 are the first embodiment, and FIG. 4 and FIG. The second embodiment, FIGS. 6 and 7, respectively show the third embodiment.

  The opening edge of the drain port member 100 is formed with a hopper-shaped tapered surface as is well known in the art.

  The drainage joint 200 is provided with a plurality of radial ribs 3 connecting the inner peripheral surface and the shaft core at the upper portion thereof, and the support portion (thrust lock mechanism) S of the drainage plug device A at the crossed shaft core portion. A locking hole 4 is formed to engage the box 1 that accommodates the box in a detachable manner.

  In the present embodiment, the drain plug 2 has a support shaft 22 vertically suspended from the center of the plug lid 12, and a shake prevention piece portion 32 radially projecting from the plug lid 12, and the support shaft 22 at a lower level thereof. A hair catcher 42 is provided, and a packing 52 is provided around the outer peripheral portion below the stopper lid 12.

  The stopper lid support shaft 22 is slidably engaged with and disengaged from the operating shaft 5 of the support portion S.

  As shown in FIG. 2, the specific configuration includes a two-step recessed portion 22 b provided in communication with the lower end of a vertical hole 22 a that is opened in communication with the axis of the support shaft 22, and the two-step recessed portion. It consists of a sleeve 6 made of synthetic resin press-fitted into the lower recess 22b-1 of 22b and an annular arc recess 7 provided on the operating shaft 5 of the support S.

The sleeve 6 is made of synthetic resin, and its lower half is slightly thinner than the upper half to ensure an elastic deformation gap between the inner surface of the lower recess 22b-1 and an axial slit 16. Is formed by projecting an arc-shaped convex portion 26a at the lower end of the elastic portion 26 formed between the slits 16, 16.
The inner diameter of the sleeve 6 is set to such an extent that the operating shaft 5 of the support S can be inserted with a slight clearance C.

  The arc-shaped convex portion 26a is sized to fit the arc-shaped concave portion, and is detached from the arc-shaped concave portion 7 only when a tensile force is artificially applied.

Therefore, the support shaft 22 can swing with respect to the operating shaft 5 by utilizing the elastic function of the elastic portion 26 in the sleeve-like object 6 by the clearance C between the operating shaft 5 and the sleeve-like object 6.
The elastic force of the elastic portion 26 is set to be weaker than the weight of the drain plug 2.

In the drain plug apparatus A such as a wash basin and a sink constructed as described above, the support shaft 22 of the plug lid 12 can swing with respect to the operating shaft 5 as described above, so that the support portion (including the box) is included. ) Even if molding errors, mounting errors, etc. occur in S and the verticality of the operating shaft 5 protruding from the box 1 is not accurate, the drain plug 2 is moved vertically to open and close the drain port b to ensure The water can be stopped (see FIG. 3).
In general, the support portion S includes a type in which the operating shaft 5 drops by its own weight, and a type in which the operating shaft 5 is urged and dropped by a return spring, and can effectively stop the water using the force.
The locking force is set to such an extent that the support shaft is disengaged from the operating shaft by an artificial pulling force, for example, about 9.8 N. By pulling out against the force, the stopper lid 12 is moved to the operating shaft 5. Can be removed.
At the time of setting, the support shaft 22 is locked to the operating shaft 5 so that the elastic portion 26 opens outward.

  Next, a second embodiment shown in FIG. 4 and FIG. 5 will be described. This embodiment shows a modified example of the locking structure of the support portion S with respect to the operating shaft 5.

Specifically, the spherical body 15 is connected to the upper end of the operating shaft 5, and a synthetic resin holding portion 22 c that holds the spherical body 15 is provided to the lower end of the support shaft 22.
As shown in the figure, the holding portion 22c is formed by notching slits 22c-1 from the middle and high portions at equal intervals in the same manner as in the above-described embodiment, toward the open portion slightly below the horizontal level of the diameter of the hollow hollow sphere. The elastic part 26 is formed between the slits 22c-1 and 22c-1, and the support part 22 is locked to the operating shaft 5 so that the elastic part 26 opens outward, and resists the elastic force. The support shaft 22 is detached from the spherical body 15 by pulling.
The locking force of this embodiment is the sliding contact force of the spherical body 15 with respect to the holding portion 22c, and suppresses the resistance during swinging smaller than that of the first embodiment.

In this embodiment, the swing range can be increased as compared with the above embodiment.

Each is inserted and magnetically attached as shown. The magnet 8 and the support shaft or the operating shaft may be directly magnetized without being inserted.
Even if the vertical angle of the operating shaft 5 protruding from the box 1 is not accurate due to a molding error or mounting error in the support part (including the box) S, the drain plug 2 moves vertically with the magnetic force. Thus, the support shaft 22 is set so as to swing with respect to the operating shaft 5 so that the drain port b can be reliably closed and water can be stopped.
The swinging is performed using the clearance C between the recess 22 d of the operating shaft 5 and the operating shaft 5, the tip of which is accommodated in the recess 22 d provided in the lower end of the support shaft 22.
The magnetizing force is set to about 9.8 N, for example, to the extent that the support shaft is disengaged from the operating shaft by an artificial pulling force, as in the first and second embodiments described above. Then, the stopper lid 12 can be detached from the operating shaft 5 by pulling out.
Since other configurations are the same as those of the first embodiment described above, the same reference numerals are given and detailed descriptions thereof are omitted.
