As shown in FIGS. 12B and 12C, when the ratchet 11 is further rotated in the opening direction by the first shaft 8, the steeply inclined surface 11c of the ratchet 11 and the first cam 12 are rotated.
The inclined surface 12b of the projection 12c formed on the upper surface of the ratchet 11 is disengaged, and the claw projection 11e of the ratchet 11 is the projection 12c of the most cam 12.
Get over. At the same time, as shown in FIG. 6, the cam 21 of the timer block 20 starts to move back toward the initial position by the urging force of the coil spring (not shown). The returning speed of the cam 21 can be arbitrarily set by the delay operation switch in the timer block 20, and in this embodiment, it is set to 5 minutes.

As shown in FIG. 6, when the cam 21 is just before its initial position, the cam 21 returns to the initial position and
The lever 22 moves counterclockwise to move the second pawl 22b.
And the engagement state with the large diameter tooth portion 25a of the No. 6 gear 25 is released. When the sixth gear 25 becomes free, the power spring 9 allows the first gear 10 of the speed increasing train wheel mechanism 45 to rotate, and the stored force of the power spring 9 closes the toilet lid 3 (broken line in FIG. 2). In the C1 direction). The closing speed of the toilet lid 3 is adjusted by the braking means BR, and the toilet lid 3 is gently lowered.

Details of the operation by the braking means BR of the toilet lid 3 and the braking means BL of the toilet seat 2 are described in Japanese Patent Application No. 63-206095.
However, the description thereof will be omitted.

The braking means that operates when the toilet lid 3 is closed is not limited to the above-mentioned embodiment, and may be an oil damper. Further, as shown in the invention of claim 1, the braking means may be omitted.

It goes without saying that the effect of the present invention will be further enhanced if a seating sensor or a human body detection sensor is attached to the toilet seat or toilet lid.

According to this embodiment, even if the toilet seat and / or the toilet lid is opened and closed immediately after the power spring and the timer are charged by the cam in the timer block, no abnormality occurs in the function, so that the reliability is high. An automatic closure device can be provided.

Further, the power spring as the rotating means may be provided only on the toilet lid, and the toilet seat side is unnecessary.

Next, another embodiment will be described.

When the bath and toilet are combined (especially in the United States), if the automatic closing device such as the toilet lid is of an electric type, very severe reliability is required due to the severe environmental conditions such as moisture resistance and water resistance. It Therefore, although the mechanical type embodiment described above is preferable, an electric type embodiment will be described.

In FIG. 14, the base ends of the toilet seat 2 and the toilet lid 3 are rotatably attached to the upper surface of the rear end of the toilet body (not shown). In the figure, an electrical equipment box 60 connected to a power supply 61 is provided on the left side, and an automatic opening / closing unit 70 is provided on the right side. The illustrated example is a toilet with hot water washing, in which the shaft provided in the electrical equipment box 60 supports one end of the rotation center axis of the toilet seat 2 and the toilet lid 3, and the rotary shaft 5A provided in the automatic opening / closing unit 70 is The end is supported.

A motor 71 is provided in the automatic opening / closing unit 70. The automatic opening / closing unit 70 is provided with an opening angle detection sensor (for example, a Hall IC) (not shown) for the toilet seat 2 and the toilet lid 3, and the positions thereof are controlled, so that the toilet seat is controlled by the control board 62, the motor 71 and the timer 200. 2 and the toilet lid 3 can be closed. Therefore, for example, if the timer 200 is set to about 5 to 10 minutes, the toilet lid 3 can be closed after 5 to 10 minutes. Since the toilet seat 2 is pushed by the toilet lid 3, only the rotating shaft 5A of the toilet lid 3 needs to be driven.

FIG. 16 shows still another embodiment. This embodiment is different from the embodiment shown in FIGS. 14 and 15 in that a dry battery 61A is used instead of the power source 61, and a solenoid 71A having a plunger 71b is used instead of the motor 71.
The only difference is that an oil damper 72 as a braking means, a power spring 9A, and a speed increasing train wheel mechanism 45A having a safety device built-in clutch 45b are provided. In the same figure, in which the opening / closing unit 70A is attached to the toilet lid, reference numeral 7
3 is a position detection Hall IC, reference numeral 5A is an input shaft of the toilet lid, reference numeral 62A is a control board with a timer IC, 74 is a battery case, and reference numeral 100 is an input gear.

The operation of the embodiment configured as described above will be briefly described. When the toilet lid is opened, the power spring 9A is charged, the position detection hole IC 73 sends the detection signal to the control board 62A, the plunger 71b of the solenoid 71A locks the speed increasing train wheel mechanism 45A,
A timer (not shown) in the control board 62A starts operating.

If the user forgets to close the toilet seat and / or the toilet lid and goes out of the toilet, and the timer (not shown) reaches the set time (about 5 to 10 minutes), the plunger 71b causes the speed increasing train wheel mechanism 45A to move. unlock. When the speed increasing train wheel mechanism 45A becomes free, the power spring 9A tries to return to the original position, so that the input shaft 5A rotates in the direction to close the toilet lid. Here, the speed increasing train wheel mechanism 45A fulfills the function of weakening the large rotational torque of the power spring 9A to drive the plunger 71b of the solenoid 71A with small power saving. In this embodiment, since the dry cell 61A is used, it is easy to replace and replenish it.

[0051]

As described above, according to the first aspect of the present invention, due to the above-described structure and operation, even if the toilet lid or the like is forgotten to be closed, the toilet lid or the toilet seat and Both toilet lids can be closed.

According to the second aspect of the invention, in addition to the above effect, when the time measuring means is forced to rotate the toilet lid in the closing direction during the time measurement, the time measuring means is returned by the returning means. Since the time measuring means is stopped and the time measuring means is returned to the initial state, it is possible to provide a highly reliable device without causing a functional abnormality in the automatic closing device such as the toilet lid. it can.

According to the third aspect of the invention, in addition to the above effects, since the rotating means is braked by the braking means when the toilet lid or the like is rotated in the closing direction, a closing impact noise or No damage will occur.
