The operation of the drive plate (6) and the like will be described with reference to FIG. FIG. 4A shows the positions of the drive plate (6), the follower plate (7), etc. in the closed state where the toilet seat (3), the toilet lid (4), etc. are seated on the toilet body (1). Has been. When the lever (21) is pushed in the direction of the arrow (30) by stepping on the foot or the like, the action part (20) moves from the stationary position (up position) to the operating position (down position), and the operating rod (26 ), The drive plate (6) is rotated clockwise, and the driven plate (7) is also engaged with the first engagement portion (14) of the cam (16) with the pin (17). It is driven to rotate (FIG. 4B). Since the toilet seat (3) is attached to the connecting portion (9) of the driven plate (7), the toilet seat (3) is opened.
[0020]
When the pressing of the lever (21) is stopped, the lever (21) is biased in the direction of pulling up the action part (20) by the spring (23), so the action part (20) is in the operating position. To the stationary position (FIG. 4C). The drive plate (6) rotates in the reverse direction (counterclockwise) in which the engagement of the first engagement portion (14) and the pin (17) is released via the operating rod (26). In (7), the pin (17) and the first engagement portion (14) are disengaged, so that they are held in the rotated position (FIG. 4B) and the toilet seat (3) remains open. During the rotation of the drive plate (6) in the reverse direction (counterclockwise), the mounting portion (25) of the drive plate (6) is connected to the rotation center and the action portion (20) of the drive plate (6). (Fig. 4 (C)), but since it is pulled by the spring (28), it rotates to a position beyond the imaginary line, and the pin (17) is connected to the second engaging portion (15).

As described above, the range of rotation is not affected by the inertial action of the drive plate (6) without using the spring (28). It can also be rotated to the position of 4 (D).
[0021]
When the lever (21) is stepped again and moved in the direction of the arrow (31), the action part (20) moves from the stationary position toward the operating position and is driven via the operating rod (26). The plate (6) rotates counterclockwise, and the driven plate (7) is also rotated by the counterclockwise direction because the pin (17) is engaged with the second engaging portion (15) of the cam (16). (FIG. 4E). The toilet seat (3) attached to the connecting portion (9) of the follower plate (7) is moved to the closed position where the toilet seat (1) is seated with the counterclockwise rotation.
[0022]
When the pressing of the lever (21) is stopped, the action portion (20) of the lever (21) is returned from the operating position to the stationary position by the spring (23). During this movement, the drive plate (6) rotates clockwise through the operating rod (26), while the driven plate (7) engages the second engagement portion (15) and the pin (17). Since it is out of alignment, it remains in the position rotated counterclockwise (FIG. 4F). In the middle of the clockwise rotation of the drive plate (6), the mounting portion (25) of the drive plate (6) is connected to the center of rotation and the action portion of the drive plate (6) as shown in FIG. Rotate to a position exceeding the imaginary line by the spring (28), inertial action, etc., and rotate to a position where the pin (17) hits the first engagement portion (14). Since this state is the state of FIG. 4A, the toilet seat can be opened or closed by operating the lever (21) in the same manner.
[0023]
As is clear from FIGS. 4A and 4D, the device of the present invention is within the range of the guide surface length of the cam (16) when the action portion (20) is in the stationary position. Thus, the pin (17) can be moved, so that only the driven plate (7) can be rotated without stepping on the lever (21). Therefore, the toilet seat and the like can be opened and closed manually, and the drive plate (6), lever (21) and the like do not move during such opening and closing operations, so there is no hindrance to manual opening and closing operations.
[0024]
Although the said Example is a case where the stationary position of an action part exists in the raised position and it becomes the position where the operation position fell, each position can also be provided in the other side. FIG. 5 is an explanatory diagram of the embodiment in which the stationary position of the action portion is at the lowered position and the operation position is at the raised position. As shown in the figure, the position of the fulcrum (22) of the lever (21), the position of the mounting portion (25) of the drive plate (6), and the position of attaching the spring (28) of the displacement means are changed. The rotation of the drive plate (6) and the driven plate (7) is the same as the embodiment shown in FIG. That is, FIG. 5 (A) showing the operation of pushing the lever (21) in the direction of the arrow (32) to open the toilet seat corresponds to FIG. 4 (A) and FIG. 5 (B) corresponds to FIG. The operation from 5C to the state of FIG. 5D is basically the same as the operation from FIG. 4C to FIG. 4D. Further, FIG. 5 (E) showing the operation of closing the toilet seat by operating the lever (21) corresponds to FIG. 4 (E), and the state shown in FIG. 5 (A) is obtained through FIG. 5 (F). The returning operation is essentially the same as the operation of returning to the state of FIG. 4A through FIG.
