JPS5930079Y2 - Simple flush toilet - Google Patents

Description

[Detailed description of the invention] The present invention relates to a simple flush toilet, in which a handle shaft 2 is rotated by the operation of the handle 1, and a diaphragm 3 is pressed by the rotation of the handle shaft 2. bowl 4
A pressure pump 5 discharges cleaning water to The shaft is slidably supported in the direction of the axis Jj, and the handle shaft 2 is provided with an engaging protrusion 10).
The present invention relates to a simple flush toilet in which a bearing 8 is provided with an engaging recess 11 that can be engaged with an engaging protrusion 10 when the nozzle shaft 2 is rotated.

By pulling the handle, the diaphragm of the pressure pump is pressed and activated, and the pressure pump discharges washing water into the bowl.The opening and closing lid of the drain 1 closes the waste discharge port of the bowl by pulling the handle. In conventional simple flush toilets of this type, when the water in the pressure pump freezes in the winter and the diaphragm cannot be pressed, the handle cannot be pulled. There was a drawback in that it became impossible to operate the discharge port opening/closing lid, and in this state it became completely impossible to use the toilet bowl.

The present invention was developed in view of the above points, and aims to provide a simple flush toilet that can be used even in cold environments where the water in the pressure pump freezes. This is the purpose.

Hereinafter, the present invention will be explained in detail with reference to examples.

The nozzle shaft 2 has a bearing 8 at the front of the toilet main body 12.
It is rotatably supported in the bearing 9 of the
The handle shaft 2 is configured to be able to slide slightly in the axial direction along the bearing hole 9.

A handle 1 is attached to one end of the handle shaft 2 on the outside of the toilet main body 12.

In addition, the crank par 13 is located in the center of the handle shaft 2.
is provided protrudingly, and a connecting rod 14 whose lower end is attached to the diaphragm 3 on the upper surface of the pressurizing pump 5 connects to the crankper 13.
It is attached to the shaft.

The discharge port opening/closing lid 7 is supported by an L axle 16 at a position below the waste discharge port 6 of the bowl 4 so as to be freely rotatable downward, and one end of the L axle 16 can be pulled and moved by rotation of the handle shaft 2. It is pivoted to a connecting rod 17.

A return spring 15 is installed between the lower part of the handle shaft 2 and the bearing 8 as shown in FIG. 2, and when the nozzle 1 is pulled in the direction of arrow A in FIG. After turning the handle 1 and releasing the hand from the handle 1, the handle shirt 1-2 returns to the idle state and moves at the same time.

The second part (10) is an engaging protrusion, when the handle shaft 2 is returned to its original position by the return peg 15).
It is protruded slightly above the handle shaft 2.

Further, reference numeral 11 in FIG. 2 denotes a four-retaining portion, which is recessed in the inner periphery of the bearing hole 9 of the bearing 8.

In Figure 1, 18 is a water tank, 19 is a hydrant that supplies tap water, etc. to the water tank 18, 20 is a ball tap that adjusts the amount of water supplied from the hydrant 19 according to the water level in the water tank 18, and 21 is an overflow. Pipe tear, water tank 18
The water inside is supplied to the pressurizing pump 5 via a U-shaped pipe 22 and a water supply hose 23 in the water supply tank 18.

Therefore, when flushing the filth in the bowl 4 from the filth outlet 6 after using the toilet, pull the handle 1 in the direction of arrow A to rotate the handle shaft 2 and rotate the connecting rod 14.
is pushed downward to press the diaphragm 3, and the cleaning water in the pressure pump 5 is discharged from the nozzle 25 into the bowl 4 via the discharge hose 24.

At the same time, the rotation of the handle shirt l-2 pulls the connecting rod 17 in the direction of arrow B, and this movement of the connecting rod 17 causes the I7 type shaft 16 to rotate and the discharge port opening/closing lid 7 to rotate downward. , the waste discharge port 6 of the bowl 4 is opened.

In this way, the filth is washed away from the filth discharge ``]6.

After this, when you release your hand from handle 1, the handle shirt)~
2 is returned to its original state by a return spring 15 and the waste is discharged]] 6 is closed by a discharge port opening/closing lid 7.

In addition, if you are in a cold region and the temperature is expected to drop and the water in the pressure pump 5 is expected to freeze, turn the handle 1 to A.
Pull it in the direction of the arrow to turn the handle shaft 2 (at this time, the engagement protrusion 10 rotates in the direction of the arrow C), and then slide the handle shaft 2 in the direction of the arrow D to engage the engagement recess 11 of the bearing 8. The protrusion 10 is engaged to lock and hold the handle shaft 2 in a rotated state.

In this state, the rotation of the handle shaft 2 causes the discharge port opening/closing lid 7 to rotate downward, and the waste discharge [ ] 6 of the bowl 4 is kept open, so that the water in the pressure pump 5 is Even if the handle 1 becomes inoperable due to freezing, the toilet can still perform its minimum function of excreting waste without any problem.

If the freeze inside the pressure pump 5 thaws, the handle shaft 2
Slide the engaging protrusion 1 into the engaging recess 11 in the opposite direction.
By disengaging 0, normal use is possible.

As described above, according to the present invention, the handle shaft can be held in a rotated state by engaging the retaining protrusion of the handle shaft with the engaging recess of the bearing, so that the dirt discharge port of the bowl is opened. It is possible to maintain the discharge port opening/closing lid in the same condition, and even if the water in the pressurizing pump freezes and the handle becomes impossible to operate, the toilet bowl can be used without any problem.

Moreover, this operation can be performed simply by engaging the retaining protrusion with the engaging recess, so even an amateur can easily perform it at home.
