A handle structure for a simple flush toilet characterized by comprising: 00. ' has been disclosed.

[Problems with conventional technology and their technical analysis]

In the handle structure of this conventional simple flush toilet (ceramic), since the rotation angle is regulated by the protrusion provided at the bottom of the handle 300, the moment applied to the protrusion is large, causing cracks etc. to occur at the attachment base of the protrusion. , it was not durable.

In addition, since the bearing part 200 is integrated with the main body of the simple flush toilet 100, the stopper and bearing part 200
has a semicircular shape, and the handle alone is 300 mm.
It was not possible to maintain the position of the shaft, and an additional bearing was required to maintain the shaft position, making it difficult to align the two. Furthermore, since it is made of ceramic, it has very poor dimensional accuracy and is difficult to process, so areas that require dimensional accuracy require post-processing using special tools.

[Technical issues]

Therefore, the present invention integrates a stopper function that regulates the rotation range of the handle into the bearing, and also provides a fixing function for these covers, thereby reducing the processing of the ceramic and stabilizing the handle operation. , can be used safely by users, and
The technical challenge is to improve the appearance.

[Technical means]

The technical measures taken to solve the above technical problems make it possible to improve durability by placing the handle's bearing itself against the bearing stopper part to regulate the rotation angle, and further improve the durability of the handle's shaft. hold (determine the center of rotation)
By making the bearing and the stopper part into an integral structure, there is no need for alignment.

[Effect of technical means]

The above technical means works as follows. That is, as shown in the accompanying drawings, the bearing that holds the shaft of the handle (determines the center of rotation) and the stopper are integrally constructed, and the shaft of the handle itself is brought into contact with the bearing stopper to regulate the rotation angle.

[Special effects produced by the present invention]

The present invention produces the following unique effects. In other words, 1. By integrating the stopper function and the cover mounting function into the bearing, the processing of ceramics is only a matter of machining the mounting hole of the bearing, and since the multiple functions are integrated as mentioned above, the need for dimensional accuracy is eliminated. Bearings, which are easy-to-process parts, were used to cover the difficult parts, making it possible to eliminate the need for any post-processing of the pottery.

2. The stopper integrated into the bearing facilitates dimensional accuracy and stabilizes the handle operation stroke.

3. By integrating the bearing function and stopper function, it can be manufactured at low cost.

4 (1) By providing the bearing with the function of attaching the cover, post-processing of the pottery can be eliminated and the cover can be attached easily.

(2) In addition, since the cover is fixed with a tapping screw, it can be easily removed and the user can clean it easily.

(3) By covering the entire bearing protruding to the outside of the toilet with a cover, the user will not have his or her hand caught in the stopper.

〔Example〕

An example illustrating a specific example of the above technical means will be described below. In the drawings from FIG. 1 to FIG. 7, a bearing 3 and a handle bracket 4 are fixed to the right side of the front housing 2 of the simple flush toilet 1 with bolts and nuts 5, and the shaft of the handle 6 is fixed to the bearing 3. The portion 6a is passed through. A handle 6 is integrated into the shaft portion 6a, and a knob 6b is attached to the tip of the handle 6 for easy operation.

Further, a cover 8 for covering the entire external protrusion of the bearing 3 is fixed by a tapping screw 8b, and this cover 8 has holes formed only at the stroke position of the handle 6.

Furthermore, the bearing 3 has protrusions 3a on the front and rear to limit the rotation of the handle 6, and a hole 3 for a tapping screw 8b for fixing the cover 8.
It has b.

a wire casing 11 that is a covering member that covers a shutoff valve wire 10 that is a first connecting member that transmits the driving force of the handle 6 to the rotational force of the shutoff valve 9;
A nut 1 is attached to the handle bracket 4 and the base bracket 13, both ends of which have a substantially U-shaped groove that can be fixed in a position where the end of the wire 10 can be rotated almost horizontally.
It is locked at 4 and 15.

Furthermore, the base bracket 13 has a hole 1 in which a spring 17 that normally biases the shutoff valve 9 in the closing direction is engaged.
It has 8.

In addition, a supply water outlet 21 is provided at the periphery of the toilet bowl 1.
However, a discharge port 22 is provided at the bottom of the toilet bowl.

A base body 19 is secured to the lower part of the discharge port 22, and the shutoff valve 9 is rotatably attached to the base body 19 by a rotary shaft so as to be able to come into contact with an elastic gasket 23 arranged on the upper surface of the base body 19 so as to have a sealing property. installed.

A roughly shaped cutoff valve lever 20 is connected to the cutoff valve 9, and a spring 17 is disposed between one end of the cutoff valve lever 20 and the base bracket 13, and a spring 17 is disposed at the other end of the cutoff valve wire 10. One end is locked. The other end of this shutoff valve wire 10 is locked to one end of the connecting plate 7.

The wire casing 11 is fixed to the handle bracket 4 by attaching the wire casing 11 to the integral threaded portion 25 of the wire casing 11 so that the attachment length of the wire casing 11 can be varied to some extent.
The handle bracket 4 is held by two nuts 14.

Further, one end of a water supply valve wire 26, which is a second connection member, is locked to the other end of the connection plate 7, and the other end is locked to a water supply valve lever 27. The locking portion between the water supply valve wire 26 and the water supply valve lever 27 is a mounting member for the water supply valve lever 27 that is integrated with a threaded portion 28 and a nut 29 formed at one end of the wire so that the length of the wire can be made variable. 30 and a nut 29 for fixing the lock.

Further, a water supply valve is built in the valve housing 31, and when the water supply valve lever 27 is pushed down, the valve is opened to supply water to the supply water inlet 32, and when the load on the water supply valve lever 27 is removed, the force of the internal spring is reduced. The water supply will automatically stop. This supply water inlet 32 communicates with the supply water outlet 21 on the periphery of the toilet bowl, and allows water to flow into the toilet bowl 1 .

Next, the effect will be explained. When the handle 6 is rotated in the direction A in the figure, the handle 6 rotates around the shaft 6a until it hits the left stopper part 3a of the bearing 3, so the cutoff valve wire 10, which is locked to the connecting plate 7, is pulled. The odor cutoff valve 9 is rotated approximately 90 degrees via a rotating shaft having a mechanism for accelerated rotation by the cutoff valve lever 20, thereby discharging the waste under the toilet bowl.

Furthermore, since the water supply valve wire 26 is also pulled, the water supply valve lever 27 is pulled down, and the supply water flows into the toilet from the discharge port 21 on the periphery of the toilet bowl, flushing out waste and cleaning the toilet bowl. When the cleaning is finished and the handle 6 is released, the cutoff valve 9 is automatically returned to its original position by the urging force of the spring 17, the handle 6 is also returned to its original position, and the water supply valve is also closed by the spring built into the valve housing 31. The handle 6 rotates in the direction B and stops when it hits the stopper portion 3a on the right side of the bearing 3.
If the water supply valve wire 26 is left slightly slack, the water supply valve lever 27 can be operated with a delay in the operation of the shutoff valve 9, and the water can be flushed after draining the waste first, making the cleaning water effective. Available for Further, since the shutoff valve 9 is quickly returned to its original position by the spring 17, the supplied water is supplied into the toilet bowl and can be used as residual water, making it difficult for filth to stick.

In addition, since the length of the water supply valve wire 26 is variable, the amount and timing of water supply, the amount of residual water, etc. can be adjusted.

Further, since the water supply valve lever 27 is connected with the wire 26, the user can operate only the water supply valve lever 27 independently, and can also flow only water during cleaning.

The effective length of the cutoff valve wire 10 can be adjusted by adjusting the length of the wire casing 11 using the nut 14. That is, if the length of the wire casing 11 is shortened, the effective length of the cutoff valve wire 10 becomes long. Therefore, ideal rotation of the shutoff valve can be obtained.
