Then, by rotating the installation member 24 forward and causing the protrusion 24c to pass between the guide groove 21a5 and the recess 21a6 and fit into the recess 21a6, it is possible to prevent the installation member 24 from rotating. . In this way, the rotation restricting portion 30 is formed by the protrusion 24c and the recess 21a6.

On the other hand, the other end side (upper side) of the leg portion 21 is provided to be rotatable and detachable with respect to the auxiliary toilet seat main body 10. Specifically, as shown in FIGS. 1, 2, and 6, the auxiliary toilet seat main body 10 has female threaded portions 15a formed on the left and right side surfaces of the front side, respectively. The female threaded portion 15a is formed on the gripping member 15, which is provided with an annular gripping portion 15b at the upper portion. A bolt member 25 is screwed into the female threaded portion 15a.

FIG. 3 shows a perspective view of the gripping member 15 viewed from inside. The gripping member 15 is integrally provided on the auxiliary toilet seat body 10 by screwing three bosses 15c corresponding to the protrusions 12 onto the three protrusions 12 protruding from the side surface of the auxiliary toilet seat body 10.

As shown in FIG. 4, the bolt member 25 is formed by a star-shaped knob portion 25a on the outer surface side, a collar portion 25b, a shaft portion 25c, and a male thread portion 25d. A plurality of ribs 25e are radially formed on the outer periphery of the shaft portion 25c. As shown in FIG. 6, when the bolt member 25 is screwed into the female threaded portion 15a, the tip of the rib 25e touches the side surface around the opening of the female threaded portion 15a (i.e., the side surface of the auxiliary toilet seat body 10 (grip member 15)). come into contact with The second leg portion 21b is located between the collar portion 25b of the bolt member 25 and the gripping member 15, and the rotation hole portion 21b3 formed at the upper end of the second leg portion 21b is coaxial with the female thread portion 15a. will be placed in In this way, with a simple configuration, the rotation hole portion 21b3 is supported around the rib 25e, and the leg portion 21 (second leg portion 21b) is rotatably supported.

The auxiliary toilet seat main body 10 has a urinary guard 14 erected downward from the inner opening edge. As shown in FIG. 7, on the lower surface of the auxiliary toilet seat main body 10, L-shaped fixed legs 16 on the rear side and movable legs 17 on the front side are provided on the left and right sides, respectively. On the front side of the movable leg 17, support legs 18 are formed on the left and right sides, respectively, to abut on the upper surface of the toilet seat.

The auxiliary toilet seat main body 10 is fixed to the toilet seat by bringing the upper surface of the horizontally extending rounded rectangular portion 16a of the fixed leg 16 into contact with the back surface of the toilet seat, and by moving the movable leg 17 to the inner edge of the opening of the toilet seat. It is done by bringing them into contact. The auxiliary toilet seat main body 10 is prevented from falling over by fixed legs 16, and is fixed to the toilet seat by movable legs 17. Note that the lower surface of the outer periphery 10a of the auxiliary toilet seat main body 10 and the lower surface (contact surface) of the support legs 18 are at the same height. Further, the outer periphery 10a that comes into contact with the toilet seat is formed of a soft material such as an elastomer, and similarly, the lower surface of the support leg 18, the outer periphery of the movable leg 17, and the fixed leg 16 that come into contact with the toilet seat are covered with a soft material such as an elastomer. It is formed.

In the auxiliary toilet seat 1 formed in this manner, as shown in FIG. 8, the auxiliary toilet seat main body 10 is fixed to the toilet seat of the toilet bowl 100, and the installation member 24 of step 20 is brought into contact with the installation floor. Thereby, the auxiliary toilet seat 1 allows the infant to easily climb up to the auxiliary toilet seat main body 10 and sit on the auxiliary toilet seat 1 using step 20. Since the child can easily breathe by gripping the grip portion 15b or pressing his or her feet against the step board 22, it is possible to encourage the infant to defecate in the toilet.

The step 20 of the auxiliary toilet seat 1 is such that the leg portion 21 rotates relative to the auxiliary toilet seat main body 10 and the installation member 24 is rotatable relative to the leg portion 21, so that the height of the toilet seat of the toilet bowl 100 is adjusted. Regardless, the bottom surface of the installation member 24 can be reliably installed on the installation surface, and the auxiliary toilet seat 1 can be easily attached to the toilet bowl 100. That is, if the toilet seat is high, the step 20 may be rotated to the rear, and if the toilet seat is low, the step 20 may be rotated to the front.

Moreover, the auxiliary toilet seat 1 can also be used only with the auxiliary toilet seat main body 10 by removing the step 20 from the auxiliary toilet seat main body 10. As a result, even for infants who have difficulty using step 20, a guardian or the like can seat the infant on the auxiliary toilet seat main body 10 and have the infant defecate. In this case, as shown in FIG. 7, by attaching the bolt member 23 that fixes the step plate 22 to the female threaded portion 15a of the auxiliary toilet seat main body 10, it is possible to prevent the female threaded portion 15a from being exposed and causing an unsightly appearance. It can be prevented. Here, the bolt member 23 is formed similarly to the bolt member 25 shown in FIG. 4, but the ribs of the bolt member 23 are formed shorter than the ribs 25e of the bolt member 25. Therefore, when the bolt member 23 is attached to the female threaded portion 15a of the auxiliary toilet seat main body 10, there is only a slight gap between the bolt member 23 and the side surface of the auxiliary toilet seat main body 10. If the step 20 is separated from the auxiliary toilet seat main body 10 in this way, storage can be easily performed.

Further, the auxiliary toilet seat 1 to which the step 20 is attached can be stored on its own by, for example, as shown in FIG. 9. In this case, the rotation of the installation member 24 is restricted by the rotation restriction section 30 (restricted state). The rotation of the installation member 24 is restricted by the rotation restriction part 30 by rotating the installation member 24 forward, climbing over the protrusion 24c (see FIG. 5) through the guide groove 21a5 (see FIG. 2), and passing through the recess 21a6 (see FIG. 2). (see Figure 2). In this way, the auxiliary toilet seat 1 can be easily stored.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment and can be implemented with various modifications.
