The upper end of the cover body 18' is positioned as close as possible to the mouth edge of the excretion opening 3 when the cover body 18' is moved under the excretion opening 3.

Next, the excretion port opening/closing device of the present invention will be explained one by one.

First, the excretor himself operates the head part 15 or the operating panel 24 provided at any other desired position to move the waist mat _a1 in one direction and lower the link _a2 . In the middle of this, that is, when the pivot point _{a2' at the upper end of the link a2 reaches} the boundary area between the arcuate hole 4 and the horizontal hole 5, the pusher part _a9 closes the excretion cover a. Press ₈ (Figure 4). The movement continues, and the excretion port 3
The excretion cover _A8 is transferred downward so as to connect the excretion port 3 and the ball portion 1 (FIG. 5). Further, after using the toilet, when the belt body _a4 is advanced in the opposite direction using the operation panel 24, the link _a2 gradually changes from the lying state to the upright state, and the excretion port 3 is closed by the waist mat _a1 .
Then, the excretion cover _a8 also moves in the opposite direction by the pusher part _a9 and returns to its original state (FIG. 1).

The pusher section _a9 has both a reciprocating and reciprocating pusher section, and the return pusher section _a9 is constructed by fixing a pressing piece to the belt body _a4 immediately behind the pressed piece 21. When the excretion cover a8 reaches the boundary area with the horizontal hole part 5, the pressed piece 21 is pushed to return the excretion cover _a8 to its original position without colliding with the waist mat _a1 .

Incidentally, in the embodiment shown in FIGS. 6 and 7, the pusher portion _a9 is not configured by providing a pressing piece on the belt body _a4 , but is constructed by using a cover provided on the support frame 18'' of the cover body 18'. The pressing piece 21 is directly fixed to the belt body _A4.In the case of this embodiment, the link
A space is secured between _the rear end of the waist pin _A1 and the front end of the excretion cover _A8 at least for the distance of movement of the pivot point _A2 ' at the upper end of A2 passing through the arcuate hole 4 and moving in a straight line. It is necessary to prevent the mat a ₁ from colliding with the cover a ₈ when the excretion port 3 is opened or closed.

In order to position the movement range of the waist mat _A1 and the excretion cover _A8 during reciprocation, limit switches (not shown) electrically connected to the operation panel 24 are provided at one end and the other end of the guide hole _A5 , respectively. The rotation of the motor 12 is controlled by contacting this limit switch with a contactor (not shown) provided at the pivot point _a2 '.

(Effects of the invention) Since the present invention is constructed as described above, it has the following advantages.

As the belt body advances in one direction, the link is laid down, and the waist pine is transferred under the adjacent laying pine, and at the same time, the excretion cover is transferred between the toilet bowl and the excretion opening, and the belt body is transferred in the opposite direction. As a result, the excretion port can be opened and closed by a series of operations in which the excretion cover returns to its original position and the waist mat is transferred to the closed state of the excretion port, thereby allowing the user to quickly deal with the act of defecating.

By positioning the excretion cover between the ball part and the excretion port by moving the belt body, the structure allows excrement to fall reliably to the ball part, so it is not necessary to use a large-scale pantograph mechanism, etc. There is no need to use the system to move the toilet up and down, it is structurally simple, does not cause a rise in manufacturing costs, and there is no need to use a flexible drain pipe, so there is no need for a special connection structure.
