Description

[Detailed description of the invention] "Field of industrial application" This invention is intended for use in simple flush toilets installed in non-flushing areas, etc., and the toilet tank sealing body that opens and closes the discharge part of the toilet bowl. The present invention relates to a mounting structure for a seal gasket that seals a gap between the seal mechanism and the like, and particularly relates to an improved structure that allows the seal gasket to be attached and removed without removing the toilet bowl.

``Conventional Technology'' Due to the slow spread of public sewerage facilities, the areas where flush toilets can be installed are limited to urban areas and their surrounding areas. For this reason, septic tanks are used for water washing, but depending on the region, the discharge of treated water may be regulated. In such areas, in addition to pump-type toilets, simple flush toilets are widely used, which can provide the same usability as a flush-type toilet without changing the conventional pump-type toilet.

Figure 4 shows a conventionally used simple flush toilet B.
The installation status is shown below. The discharge section 20 of the simple flush toilet bowl B is provided with a storage box 26 that accommodates a sealing mechanism 21 for blocking bad odors from the toilet tank and wind blowing up from below. The storage box 2
6, the simple flush toilet bowl B is connected to a defecation pipe 27 leading to the toilet tank.

FIG. 5 is an enlarged cross-sectional view of the sealing mechanism 21 of the conventional simple flush toilet B using an automatic flapper mechanism of an automatic opening/closing type as an example of the sealing mechanism 21. A toilet tank sealing body 22 is provided at the discharge port 23 at the bottom of the toilet bowl B ₁ of the simple flush toilet bowl B to open and close the discharge port 23 . The illustrated toilet tank sealing body 22 is of a type that opens and closes the discharge port 23 by rotation. When waste falls into the receiving part 22a, its weight causes the toilet tank sealing body 2 to
2 opens and rotates as shown by the two-dot chain line to discharge the waste, and when the discharge is finished, it automatically returns to the original closed state by the action of the weight 22b provided at the side end of the toilet tank sealing body 22. do.

A seal packing 24 is attached to the discharge port 23 of the above-mentioned simple flush toilet bowl B. The seal packing 24 is for sealing the gap between the receiving part 22a of the toilet tank sealing body 22 and the discharge port 23 to form a water storage part. Normally, the simple flush toilet B is not provided with a trap that is provided in a flush toilet. Therefore, as an alternative to the trap, a water reservoir is formed at the outlet 23 which is closed by the seal mechanism 21, and the water is sealed. This prevents the dirt from adhering to the receiving portion 22a and facilitates the discharge of dirt. The seal packing 24 is essential for forming this water reservoir. Further, the seal packing 24 is
When the toilet tank sealing body 22 automatically returns after discharging waste, its metal or resin receiving portion 22a
It has the effect of reducing the impact of collision with the discharge port 23 of the ceramic toilet bowl _B1 , thereby preventing damage to the toilet bowl B and the toilet tank sealing body 22, and at the same time reducing unpleasant collision sounds.

"Problems to be Solved by the Invention" The conventional mounting structure for the seal gasket 24 is as shown in _FIG . The upper surface of the gasket 24 and the lower end surface of the discharge port 23 were bonded and fixed. By the way, due to deterioration etc., seal packing 24 times every 2 to 3 years.
However, since the installation structure was as described above, when replacing the seal gasket 24, the main body of the toilet B had to be removed from the installation location and turned over, which was a huge hassle. It required time and effort.

"Means for Solving the Problems" In order to solve the above-mentioned problems, the present invention makes it possible to easily attach and detach the seal gasket from the inside without removing the toilet bowl. The configuration will be specifically explained using FIG. 1 showing an embodiment of the present invention.

The features of the present invention include the discharge part 1 of the simple flush toilet A and the toilet tank sealing body 12 that opens and closes the discharge part 1.
This is a mounting structure for a seal gasket 3 for sealing a gap with a seal mechanism 2 such as the above-mentioned simple flush toilet A.
The seal packing 3 is locked to a locking part 4 provided around the lower end or near the lower end of the inner circumferential surface 1a of the discharge part 1.

A storage box 6 housing a sealing mechanism 2 is provided below a discharge port 10 provided at the bottom of the toilet bowl A ₁ of the simple flush toilet A. The storage box 6 also serves as a connection between a defecation pipe 7 leading to the toilet tank and the simple flush toilet A. In this embodiment, the sealing mechanism 2 is an automatic flapper mechanism of an automatic opening/closing type.

The simple flush toilet A is connected to the top surface of the storage box 6 at the bottom surface of the toilet bowl A ₁ by a clamp 8, a tightening band 9, etc. Of course, this connection can also be made using bolts and nuts. A seal gasket mounting member 11 is provided on the upper surface of the storage box 6 in a continuous manner with a discharge port 10 provided on the bottom surface of the toilet bowl _A1 . The seal packing mounting member 11 is a cylindrical member hanging from the upper surface of the storage box 6, and its inner diameter is the same as or slightly larger than the diameter of the discharge port 10. Above seal packing mounting member 1
A locking portion 4 of the seal packing 3 consisting of an annular projection projecting inward is provided at the lower end of the seal packing 3, and the inner circumferential surface 1 of the seal packing mounting member 11
A female screw for screwing together the sealing stopper 5 is carved in 1a. The length of the female thread is
This length is such that when the sealing stopper 5 is separated from the sealing packing 3, a separation distance t can be obtained that allows the sealing packing 3 to be attached and removed.

FIG. 2 is an exploded perspective view of the packing stopper 5, the seal packing 3, and the seal packing mounting member 11.

The seal packing 3 is a flexible ring-shaped member made of Teflon or the like. The outer diameter substantially matches the inner diameter of the seal packing mounting member 11, and the inner diameter is the same as or slightly larger than the diameter of the discharge port 10. A locking groove 3a that fits into the locking portion 4 is provided on the outer peripheral surface. When the locking groove 3a is fitted into the locking portion 4, the lower end of the seal gasket 3 is connected to the seal gasket mounting member 11.
It protrudes slightly from the lower end of the toilet bowl A, and seals the gap between the discharge part 1 of the toilet bowl A and the sealing mechanism 2.

On the other hand, the packing retainer 5 is also a ring-shaped member having an inner and outer diameter that is approximately the same size as the seal packing 3. A male screw 5a corresponding to the female screw carved on the inner peripheral surface 11a of the seal packing mounting member 11 is provided on the outer circumferential surface, and a notched groove 5b for rotating the packing holding tool 5 is provided on the upper surface. It is provided. Therefore, by screwing the sealing stopper 5 onto the inner peripheral surface 11a of the seal packing mounting member 11 and using the rotating tool 13 as shown in FIG.

This is done by pressing the seal packing 3 by screwing it into the female thread on the inner circumferential surface 11a of the seal packing mounting member 11 and tightening it.

By the way, 2-3 times after starting to use the simple flush toilet A.
As mentioned above, it is necessary to replace the seal packing 3 every year. Therefore, a method of replacing the seal packing 3 in this embodiment will be described. While leaving the simple flush toilet bowl A as it is, rotate the seal retainer 5, which is screwed onto the inner circumferential surface 11a of the seal seal mounting member 11, from the inner surface of the toilet bowl _A1 using a rotating tool or the like. and separate it from the seal packing 3. Next, the seal packing 3 is removed from the locking part 4. In this case, since the seal packing 3 is flexible, it is necessary to remove it with bare hands from the outlet 10, which has the same or slightly smaller outer diameter than the outer diameter of the seal packing 3. It can be pulled out by hand or by using an appropriate tool. To subsequently install a new seal packing 3, the above procedure may be reversed. That is, the seal gasket 3 is pushed into the seal gasket mounting member 11 from the outlet 10 of the toilet bowl A ₁ by utilizing its flexibility, and the locking groove 3a is inserted into the locking portion while taking the posture of the seal gasket 3 into consideration. 4. Push down until it is engaged. When the locking groove 3a is fitted into the locking portion 4 and locked, the sealing pad 3 is rotated again to press the sealing pad 3.

For example, the structures of the locking groove 3a of the seal packing 3 and the locking portion 4 of the seal packing mounting member 11 can be shaped as shown in FIGS. 3a to 3f. That is, the locking part 4 is not only provided at the lower end of the seal packing mounting member 11 [FIG. 3 a, b, c], but also slightly above the lower end of the seal packing mounting member 11 [FIG. 3 d,
e, f] is also possible. In addition, the tip of the locking part 4 is sloped upward [Figures a and d], and the tip of the locking part 4 is provided with a rib for preventing slipping off [Figures b and 4]. [e], Furthermore, without forming a locking groove, a locking flange 3b is provided around the upper part of the outer circumferential surface of the seal packing 3 to lock it to the locking part 4, as shown in FIG. It may also be possible to

Further, in the embodiment, a case was explained in which an auto flapper was used as the sealing mechanism 2, but other sealing mechanisms that require the seal packing 3, for example, opening and closing the discharge port by operating the pedal by stepping on the pedal, were described. It is also possible to apply it to a foot-operated flapper mechanism, etc.

"Effects of the Invention" As described above, according to the present invention, the seal packing can be replaced without removing the toilet bowl, so that aging of the seal packing can be quickly dealt with. Therefore, the discharge part of the toilet bowl is always kept in a well-sealed state, so that bad odors, updrafts, and flies are prevented from entering the toilet. Furthermore, as shown in the embodiment, if the diameter of the toilet bowl outlet is the same as or slightly smaller than the inner diameter of the seal packing and the packing retainer,
It is possible to prevent dirt from adhering to the inner peripheral surface of the seal packing mounting member, and since the packing retainer does not separate when unscrewing, there is no chance of powder being lost due to incorrect operation. , it makes it difficult to see the deep part of the discharge port, which improves the aesthetic appearance.
