DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the drawings. In the present embodiment, the toilet seat opening / closing device attached to the upper surface of the toilet body will be described. However, the toilet lid opening / closing device for the toilet seat can be obtained with the same structure and effect as the toilet seat opening / closing device. Only the toilet lid opening / closing device will be described.

Reference numeral 11 denotes a Western-style toilet body, and a pair of bearings 12 is provided on the upper surface of the Western-style toilet body 11, and a support shaft 13 is rotatably provided between the bearings 12. It is erected and supported. The intermediate portion of the support shaft 13, that is, the portion excluding the joint portion with the bearing 12 is shown in FIGS.
As shown in FIG. 3, the bearing portion 16 provided on the toilet seat 15 is formed on the flat portion 14 having an oval cross section.
The support shaft 13 is structured so that the support shaft 13 is rotated when the toilet seat 15 is opened and closed.

The flat portion 14 of the support shaft 13 is shown in FIG.
As shown in FIG. 5, a substantially symmetrical fan-shaped through hole 18 formed in the power transmission plate 17 is loosely fitted therein, and a gear 19 is formed on the arc surface of the power transmission plate 17. This gear 1
Reference numeral 9 is meshed with a power transmission gear 21 provided in a shock absorber 20 such as an oil damper or an air damper having a well-known structure. This shock absorber 20 is fixedly held at a desired position on the toilet body 11, and a one-way clutch (not shown) is interposed between the power transmission gear 21 and the damper mechanism, so that the power transmission gear 21 is For example, as shown in FIG. 4, it is configured to rotate freely in the counterclockwise direction (A), but to rotate in the clockwise direction (reverse A direction) with a braking force applied.

The structure of this embodiment has been described above. Next, the operation thereof will be described. The through hole 18 provided in the power transmission plate 17 of the toilet seat 15 and the spindle 1 loosely fitted in the through hole 18.
A play by a symmetric fan-shaped through hole 18 is provided between the holes 3 and 3. Therefore, when the toilet seat 15 is to be opened from the closed position of the toilet seat 15 shown in FIGS. 3 and 4, the support shaft 13 rotates together with the rotation of the toilet seat 15 due to the above-mentioned play, and the flat surface 14 of the support shaft 13 moves. It is lightly rotated without feeling a rotational load until it comes into contact with the locking surface 22 of the through hole 18. Thereafter, when the toilet seat 15 is further opened, the power transmission plate 17 starts to rotate in the (A) direction due to the engagement between the flat surface 14 and the through hole 18, whereby the power transmission gear 2 of the shock absorber 20 is rotated.
Although 1 is rotated in the A direction, the power transmission gear 21 rotates in the (A) direction without braking force by the action of the one-way clutch as described above, so that the toilet seat 15 receives the entire braking force. It can be opened smoothly and quickly.

When the toilet seat 15 which is opened next is closed, initially the engaging surface of the through hole 18 and the flat portion 1 of the support shaft 13 are closed.
Since there is a play between the toilet seat 15 and the toilet seat 15, the toilet seat 15 is partially closed without load, but if the closing operation is continued beyond that, the flat surface 14 of the support shaft 13 and the through hole 18 are closed. The provided locking surface 22 and the contact side 23 on the opposite side come into contact with each other, and thereafter, the operation of the support shaft 13 causes the power transmission plate 17 to rotate in the reverse A direction. Since the cushioning action, that is, the braking force is applied, the toilet seat 15 is gently closed, the impact with the toilet body is prevented when the toilet seat is closed, and the impact noise is prevented or damage is prevented. Is.

Although the power transmission gear of the shock absorber is provided with the one-way clutch in the above embodiment, the description has been made.
A power transmission gear without this one-touch clutch can also be used. In this case, when the toilet seat is opened, the braking force by the shock absorber acts from the middle of the opening operation, but this does not hinder the achievement of the object of the present invention.

[0012]

As described above, the present invention includes a toilet seat / toilet lid,
A support shaft 13 for rotatably supporting the toilet seat / lid, a power transmission plate 17 engaged with the support shaft with play in the rotation direction of the support shaft, the power transmission plate 17 and a gear. Since it is a toilet seat / toilet lid opening / closing device having a shock absorber 20 connected thereto, according to this, a shock absorber to be engaged with a support shaft of the toilet seat / toilet lid with desired play in the rotational direction is provided. The provision of such an effect can prevent the impact with the toilet body, especially when the toilet seat / toilet lid is closed due to its own weight, and thus can prevent damage to the toilet bowl, generation of impact noise, and the like.
