Description

[Detailed description of the invention] The invention relates to a simple flush toilet.
In particular, the present invention relates to a drive device for a simple flush toilet that can seal the outlet of the toilet.

Conventionally, as a simple flush toilet, the toilet tank of a pump-type toilet can be used as is, and a rotary or other odor cut-off valve is installed between the toilet outlet and the toilet tank or sewage pipe, and this and the water supply. Some valves are linked and can be opened and closed using a handle. Some of these are equipped with a handle stopper to keep the stroke of the handle constant.
However, since this handle stopper is disposed outside the toilet bowl, it is conceivable that the user may accidentally pinch his/her finger. In addition, because toilet bowls are generally made of ceramic, their dimensions tend to vary, and with a stopper that is fixed to the toilet bowl in advance, there is a large error in the opening and closing timing of the shutoff valve and water supply valve, which prevents the shutoff valve from closing completely. The drawback was that it would not open completely. Furthermore, adjusting these requires extremely complicated work.

The object of the present invention is to stabilize the handle position by providing a handle stopper inside the toilet bowl, reduce the opening/closing error of the shutoff valve due to variations in the toilet bowl itself, and facilitate its adjustment.

In order to achieve the above object, the connecting plate to which the handle is fixed is connected to the lever of the odor cutoff valve and the lever of the water supply valve using connecting members, and the connecting member connecting the connecting plate and the odor cutoff valve is covered with a covering member. A bracket is provided that adjustably fixes one end of the covering member and has a protrusion that restricts the range of rotation of the connecting plate.

With this configuration, the protrusion provided on the bracket restricts the rotation of the connecting plate to which the handle is fixed, thereby stabilizing the handle position. In addition, by fixing the covering member to a bracket that has protrusions that restrict the rotation of the connecting plate, the effective length of the connecting member is stabilized, which prevents the connecting member from being pulled too much or not enough. It is possible to reduce the opening/closing error of the shutoff valve due to variations in the size of the valve. this is,
This is because the bracket itself can be manufactured with high precision, so that the distance between the fixed position of the covering member and the protrusion that restricts the rotation of the connecting plate can be kept constant. In addition, since the length of the covering member can be adjusted, errors due to variations in the mounting position of the bracket can be absorbed, and ideal rotation of the shutoff valve can be obtained.

Next, an embodiment according to the present invention will be described based on FIGS. 1 to 5.

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. A shaft portion 6a of a handle 6 is passed through the bearing 3, and a connecting plate 7 is inserted therein. It is attached so that it can rotate freely and not come off by being held between E-rings 8, and this shaft part 6a has a
The handle is integrated.

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;
Both ends of the wire 10 are locked with nuts 14 and 15 to a handle bracket 4 and a base bracket 13 having a substantially U-shaped groove 12 that allows the end of the wire 10 to be fixed in a substantially horizontal position.

In addition, the handle bracket 4 includes a handle 6.
so as to limit the rotation of the connecting plate 7 that is integrated with the
It has protrusions 16 at the front and rear, and further includes a base bracket 1.
3 has a hole 18 in which a spring 17 that normally biases the shut-off valve 9 in the closing direction is engaged, and the base body 19 is free from the rotation of the shut-off valve lever 20 without being affected by the rotation of the shut-off valve 9. It is fixed approximately in the center.

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 a shutoff valve 9 is rotatably attached to the base body 19 by a rotary shaft 24 so as to be able to come into contact with an elastic or packing 23 arranged on the upper surface of the base body 19 so as to have a sealing property. It is being

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 19, 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 using two nuts 14 attached to the threaded portion 25 at one end of the wire casing 11 so that the attachment length of the wire casing 11 can be varied to some extent. to hold.

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 an attachment member 30 to 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 varied. and a nut 31 for fixing the lock.

Further, a water supply valve is built into 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 at 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 shown in the figure, the connecting plate 7 rotates around the shaft 6a until it hits the left protrusion 16 of the handle bracket 4, so the shutoff valve wire 10 that is locked to the connecting plate 7 is pulled. The odor cutoff valve 9 is rotated through a rotating shaft 24 which has a mechanism for rotating the cutoff valve lever 20 at an accelerated rate by pulling the cutoff valve lever 20.
Rotate 90 degrees and drain waste to the bottom of 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 supplied water flows into the toilet from the discharge port 21 on the periphery of the toilet, flushing out waste and cleaning the toilet. 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 stops when the connecting plate 7 hits the right protrusion 16 of the handle bracket 4.

If you leave the water supply valve wire 26 slightly slack,
The water supply valve lever 27 can be operated with a delay in the operation of the cutoff valve 9, and the water can be flushed after draining the waste first, so that the cleaning water can be used effectively. 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 shutoff valve wire 10 becomes long. Therefore, ideal rotation of the shutoff valve can be obtained.
