DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below based on embodiments shown in the drawings.

1 to 3 relate to a first embodiment in which the present invention is applied to a toilet of a type in which only a toilet seat is installed,
FIG. 1 is a longitudinal sectional view showing the toilet seat opening/closing mechanism 1, FIG. 2 is a partially sectional plan view of the toilet seat opening/closing mechanism 1, and FIG. 3 is a longitudinal sectional view showing the pedal mechanism 2. In this embodiment, as shown in FIG. 1, a toilet seat box 4 is fixedly installed on the rear upper surface of the toilet main body 3, and a toilet seat 6 is rotatably attached to the toilet seat box 4 via a shaft 5. It is pivotally supported.

The toilet seat opening/closing mechanism part 1 is built into the toilet seat box 4. That is, a pinion 7 is fixed to the toilet seat shaft 5 in the toilet seat box 4, and the pinion 7 meshes with a gear 8. An arm 10 is attached and fixed to the shaft 9 of the gear 8. In addition, on the inner wall surface of the toilet seat box 4,
A shock absorber 11 is installed to reduce the swinging of the arm 10 in the counterclockwise direction in FIG. 1.

On the other hand, the pedal mechanism section 2 is arranged near the toilet main body 3, and as shown in FIG. 3, a foot-operated pedal 14 is rotatably attached to the housing 12 via a return spring I3. There is. A sector float 15 is provided on the other end side of the pedal 14.

This gear 15 includes a pusher 16 and a sector large gear 1.
The pinion 18 is meshed with the pinion 18 provided with 7. The pusher 16 connects to the toilet seat closing operation cable 2 via the swinging piece 19.
0, and sector large gear 1.
7 is adapted to operate a toilet seat closing operation cable 22 via a rack 21. In addition, in Figure 3, 2
3 is a spring for returning the closing operation cable 20.

The other end of the toilet seat closing operation cable 22 is inserted into an arm 10 for rotating the toilet seat shaft 5, and is sealed by a stopper 24. Therefore, operation cable 2
2 can rotate the arm 10 clockwise in FIG. 1 via the stopper 24, but can freely move relative to the arm 10 in the opposite direction. On the other hand, a contact piece 25 is attached to one end of the toilet seat closing operation cable 20, which corresponds to the base of the arm LO. In the state shown, the arm 10 is pushed by a stroke l in the direction of the counter-hour hand in the figure.

Next, the operation mode of the first embodiment device configured as described above will be explained.

First, as shown in FIG. 1, it is assumed that the toilet seat 6 is placed on the upper surface of the toilet main body 3 around the toilet bowl in a reclining position and is in a closed state. From this state, when a man goes to do some errands, he approaches the toilet bowl body 3 and depresses the foot pedal 14 by about 15 degrees while standing, and the sector float 15 moves in the clockwise direction as shown in FIG. Start turning. As a result, the pusher 1 attached to the binion 18
6 and the sector large gear 17 begin to rotate.

Due to the rotation of the pusher 16, the swinging piece 19 is pushed to the left in FIG. It is moved by the stroke l to the right in the figure.

However, in this state, the arm lO is in the state shown by the substantially solid line in FIGS. 1 and 2, and the movement of the stroke l of the abutment piece 25 is an independent operation.

Also, due to the rotation of the sector large gear 17, the rack 21 is moved to the third position.
Move by stroke L to the right in the figure. This results in
The toilet seat closing operation cable 22 is pulled to the left in FIGS. 1 and 2, and the stopper 24 rotates the arm 10 approximately 55 degrees clockwise in FIG. 1. Therefore, the rotation angle of the pinion 7 is expanded through the gear 8, and the pinion 7 rotates approximately 110 degrees counterclockwise in the figure, and as a result, the toilet seat 6 is moved from the reclined position through the toilet seat shaft 5. The child will be able to open his/her body to a standing position. That is,
A male user can open the toilet seat 6 and relieve himself by simply stepping on the pedal 14 without using his hands while standing near the toilet main body 3. . Therefore, it is possible to use the toilet bowl main body 3 without having to bend down or take an unreasonable posture, which is extremely convenient.

The relationship between the depression angle of the foot pedal 14 and the movement strokes 1 and L of the operating cables 20 and 22 for opening and closing the toilet seat is as shown in FIG.

After the toilet seat 6 is opened, when the foot is removed from the foot pedal 14, the fj2 return spring 13 rotates the pedal 14 back to the state shown by the solid line in FIG. This rotational movement causes the rack 21 to return to the position shown by the solid line in FIG. 3 via the large and small sector gears 15, 17. This rack 2
The operation No. 1 is transmitted to the tip side of the toilet seat closing operation cable 22. However, the toilet seat closing operation cable 22 is inserted into the arm 10 in a loose state, and since the toilet seat 6 is in the open state, the cable 22 independently moves to the right in FIG. It will return to its position. Therefore, in this state, the arm 10 is released from the restraint of the part 24 of the toilet seat closing operation cable 22, and it is possible to manually close the toilet seat 6 from the upright position to the collapsed position. It is.

On the other hand, while the foot pedal 14 is in the middle of its return operation,
The pusher 16 comes into contact with the swing piece 19.

However, the rotation return operation of the pusher 16 is in the clockwise direction in FIG. 3, and the swinging piece 19 can freely swing in the direction of the hour hand.

Therefore, the swing of the swing piece 19 is caused by the movement of the toilet seat closing operation cable 2.
0 is not moved, that is, foot pedal 1
The return operation 4 is unrelated to the opening/closing operation of the toilet seat 6.

Next, we will explain the case where a male user operates the foot-operated pedal 14 to repeatedly lower the toilet seat 6 from the open state to the closed state after using the toilet body 3. When the pedal 14 is lightly depressed, the pinion 18 and pusher 16 . Sector large gear 17
begins to rotate counterclockwise as shown in Figure 3. As a result, the pusher 16 moves the swinging piece 19 by a stroke l to the left in FIG. 3, and moves the contact piece 25 attached to the tip of the toilet seat closing operation cable 20 to the right in FIG. When the toilet seat 6 is in the open state, the arm 10 is in the position shown by the chain line in FIG. Therefore, the contact piece 2
5 pushes arm lO by a stroke of 4 minutes and rotates it counterclockwise. Therefore, the toilet seat shaft 5 is rotated clockwise via the gear 8 and pinion 7, and the toilet seat 6 is closed from the upright position to the 1!1 down position. Of course, the impact of the closing operation of the toilet seat 6 is alleviated by the shock absorber 11 at its terminal end, allowing it to come into gentle contact with the toilet main body 3.

After returning the toilet seat 6 to the closed state by rotating the pusher 16 by one minute of the stroke, the foot pedal 14
Therefore, when operating the toilet seat 6 from the open state to the closed state, the foot pedal 14 only needs to be depressed slightly. Through rank 21 also some amount, 3rd
Move to the right in the diagram. However, this movement of the stopper 24 at the tip of the toilet seat closing operation cable 22 occurs when the arm 10 is in the In line state shown in FIG. 1, and does not engage with the arm IO. The pedal operation for closing the toilet seat 6 is performed independently of the arm lO, and the toilet seat 6 is never opened.

5 and 6 show a second embodiment in which the present invention is applied to a toilet main body 3 of a type in which a toilet seat 6 and a toilet lid 26 are installed together. This embodiment is intended to be used as a toilet main body 3 used especially for women in public restrooms and the like. In this case, the toilet lid shaft 27 is the same as the first embodiment described above, except that only the toilet lid 26, which is rotatably inserted into the toilet seat shaft 5, can be opened and closed. , the explanation here is omitted.

Further, FIGS. 7 and 8 show a toilet main body 3 of a type in which a toilet seat 6 and a toilet lid 26 are installed together, and the toilet seat 6 can be opened and the toilet lid 26 can be closed. This shows a third embodiment in which it is possible to do this. In this embodiment, the operation cable 22 for opening the toilet seat is inserted loosely into the arm lO that is linked to the toilet seat shaft 5, and the contact piece 25 at the tip of the operation cable 20 shown in FIG. 1 is connected to the toilet lid shaft 5.
The arm 28 is disposed opposite to the base of the arm 28 which is interlocked with the arm 7.

As a result, when the toilet main body 3 is used, when the toilet seat 6 is opened by pressing the pedal 14 and operating the operating cable 22, the toilet lid 26 also opens in an integrated manner.

Further, after using the toilet main body 3, if the pedal 14 is depressed slightly and the toilet lid 26 is closed by getting caught in the operation cable 20, the toilet seat 6 is also closed together.

The other configurations and effects are the same as in each of the embodiments described above.

FIG. 9 shows a fourth embodiment in which the opening/closing mechanisms of the toilet seat 6 and toilet lid 26 of the third embodiment shown in FIGS. 7 and 8 are provided in a protruding manner toward one end of the toilet seat box 4. It is something. The basic configuration and effects are exactly the same as in the third embodiment.

By the way, the present invention is not limited to each of the embodiments described above, and can be modified as appropriate. Although this is done via the pedal 17, it is also possible to connect it directly to the rotating part of the pedal 14. It is also possible to attach the arms 10 and 2B directly to the toilet seat shaft 5 and the toilet lid shaft 27.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to open and close the toilet seat and the toilet lid by simply stepping on the foot pedal while standing near the toilet main body. Therefore, the user does not have to bend down or take an unreasonable posture to open and close the toilet seat and toilet lid, which is extremely convenient. Furthermore, since there is no need to approach the filth and the like attached to the inner surface of the toilet bowl, there is no need for discomfort.
