Detailed ways

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings, common reference signs are assigned to corresponding structural elements.

FIG. 1 is a perspective view of the appearance of an infant toilet (potty) 1 to which the present invention is applied; FIG. 2 is a diagram showing installation of main components of the infant toilet 1 of FIG. 1; FIG. Bottom view of a toilet for infants and toddlers.

The toilet 1 for infants includes: a toilet body 10 ; a middle bowl 20 ; a toilet seat (auxiliary toilet seat) 30 mounted on the toilet body 10 ; a cover member 40 covered on the toilet body 10 ; and an auxiliary step member 50 , which is accommodated under the toilet body 10 . The lid member 40 is attached so as to be able to pivotally move relative to the toilet body 10 , that is, to be able to be opened and closed. In addition, in this specification, the back side when seated on the toilet 1 for infants and young children, that is, the lid member 40 side after opening is defined as the "rear" side, and the opposite side is defined as the "front" side.

Before explaining each component in detail, the usage method of the toilet 1 for infants and young children to which this invention is applied is demonstrated.

4 is a diagram showing the installation of the auxiliary step member 50 of the toilet 1 for infants and young children in FIG. 1; FIG. 5 is a diagram showing the state of two steps of the toilet 1 for babies and young children in FIG. 1 is a diagram of a step state of the toilet 1 for infants and young children.

As the first stage of toilet training without diapers, as shown in FIG. 1 , the toilet 1 for infants and young children can be used as a general potty. Afterwards, as the child grows up, training is given to use a general (adult) toilet instead of a potty. The opening of the generally used toilet seat for infants is relatively large, and there is a possibility of sliding into the toilet when the infants directly sit down. In order to prevent slipping, a toilet seat 30 is mounted on the general toilet seat as an auxiliary toilet seat. At this time, the cover is used as a step for the child to sit in front of the toilet seat of the general toilet seat, that is, as an elevator, or as a step for easy use of force when defecating when sitting facing the front, that is, a footing. Part 40 and auxiliary step part 50.

The auxiliary step member 50 is removed from below the stored toilet body 10 , and as shown in FIG. 4 , is attached to the upper portion of the toilet body 10 from above the lid member 40 in the closed state. As shown in FIG. 5 , the toilet 1 for infants and young children equipped with the auxiliary step member 50 functions as a step having two steps. The auxiliary step member 50 on the cover member 40 is provided as a second step. This state is called a two-step stair state. By arranging the infant toilet 1 in the two-stage stair state on the front of the general toilet seat 2 to which the auxiliary toilet seat 30 is attached, the infant toilet 1 can be used as a lift and a stand.

As the child grows further, the auxiliary step member 50 will no longer be needed. In this case, the auxiliary step member 50 is detached from the upper portion of the toilet body 10 and accommodated under the toilet body 10 again. As shown in FIG. 6 , the infant toilet 1 from which the auxiliary step member 50 is removed functions as a step having a first step with the lid member 40 in the closed state as the first step. This state is called a first-order step state. By arranging the infant toilet 1 in the one-step state on the front of the general toilet seat 2 on which the auxiliary toilet seat 30 is installed, the infant toilet 1 can be lowered as compared with the two-step state. Use the lifting platform and foothold of the steps. In addition, the one-step step state can be used as a foothold when washing hands or brushing teeth in the bathroom, in addition to a foothold when defecating.

As described above, by selecting the one-step step state and the two-step step state according to the growth of the infant, it is possible to adjust the heights of the elevating platform and the stand to be optimal.

Next, each member constituting the toilet for infants will be described.

First, the middle bowl 20 which is accommodated in the toilet body 10 and stores excrement will be described. FIG. 7 is a perspective view of the middle tub 20 of the infant toilet 1 of FIG. 1 ; FIG. 8 is a side view of the middle tub 20 of FIG. 7 . The middle tub 20 is accommodated in the toilet body 10 so that the front side in FIG. 7 and the left side in FIG. 8 are arranged on the front side of the infant toilet 1 . The middle tub 20 has a side wall 21 and a bottom wall 22 defining a space for storing excrement. The upper end of the side wall 21 is bent outward across the entire circumference to form an outer edge portion 23 . The outer edge part 23 of the front-end part of the barrel 20 extends upward compared with other parts, and has the notch part 23a. The part of the outer edge part 23 which has the notch part 23a is grasped when taking out the middle bowl 20 from the toilet main body 10. As shown in FIG.

On the bottom wall 22, a convex separation convex portion 22a extending in the left-right direction is formed. The separation convex part 22a is formed in the center part in the longitudinal direction of the middle tub 20, or nearer the front than a center part. The middle barrel 20 has the separating convex portion 22a, so that when the infant excretes, urine is stored in the front side of the separating convex portion 22a, and stool is stored in the rear side of the separating convex portion 22a. That is, mixing of urine and stool in the middle tub 20 is prevented. Therefore, it is unlikely that the cleaning of the middle tub 20 becomes difficult due to the mixing of urine and stool. As a means for preventing the mixing of urine and stool, instead of the convex separating convex portion, a protruding separating wall portion extending in the left-right direction from the bottom wall 22 may be used. In addition, the middle tub 20 is formed by integrally molding hard plastic such as polypropylene.

FIG. 9 is a perspective view of the auxiliary toilet seat 30 of the infant toilet 1 of FIG. 1 , and FIG. 10 is a perspective view of the rear surface of the auxiliary toilet seat 30 of FIG. 9 . In addition, in order to simplify description, even when the toilet seat 30 is not used as an auxiliary toilet seat, it is called the auxiliary toilet seat 30.

The auxiliary toilet seat 30 is mounted on the toilet body 10 so that the depth side in FIG. 9 and the near side in FIG. 10 are arranged on the front side of the toilet 1 for infants and young children. The auxiliary toilet seat 30 is configured as a toilet seat that can also be mounted on a general toilet, and has a ring-shaped seat portion (auxiliary toilet seat body) 31 , a urine barrier 32 for blocking urine, and wing portions 33 . The seat part 31, the urine baffle 32, and the wing part 33 are integrally formed by hard plastics, such as polypropylene. The urine baffle 32 may also be provided as a separate component that can be attached or detached from the seat 31 .

The seat part 31 has: a seat surface 34, which is used for infants to sit; an inner wall 36, which extends downward from the inner peripheral side of the seat surface 34 and divides to form an opening 35; Extend below. On the front end side of the seat surface 34, a raised portion 34a raised in a spherical shape is formed. On the front end side of the inner wall 36, a concave portion 36a is formed adjacent to the protruding portion 34a and facing forward. The concave portion 36a of the inner wall 36 extends upward to the inner surface of the raised portion 34a according to the shape of the raised portion 34a, and forms the urine baffle 32 together with the inner surface of the raised portion 34a. The front surface 32a of the urine barrier 32, that is, the back surface of the concave portion 36a of the inner wall 36, and a pair of rib members 32b protruding from the left and right sides of the front surface 32a are used for fixing to a general toilet seat.

The wing portion 33 is formed to protrude from the seat portion 31 in the left-right direction at the left-right rear of the seat portion 31 . Since the auxiliary toilet seat 30 has a pair of wing parts 33, the small seat part 31 for infants can be stably mounted on the general toilet seat. In addition, a pair of rubber leg members 60 are attached to the back of the wing portion 33 , and one rubber leg member 60 is attached to the back of the front end portion of the seat portion 31 , totaling three rubber leg members 60 . The rubber leg member 60 is used for the purpose of preventing slippage with the general toilet seat on which the auxiliary toilet seat 30 is mounted. The rubber leg member 60 is formed of thermoplastic elastomer, for example, and is fixed by screws. In addition, in FIG. 10 , one rubber foot member 60 of the wing portion 33 is omitted.

A pair of cylindrical holding members 38 to which toilet seat fixing members 70 described later are attached are formed on the left and right rears of the back surface of the auxiliary toilet seat 30 . In addition, a toilet seat fixing member 70 is already attached to one holding member 38 . The holding member 38 has four holding protrusions 39 protruding radially from the central axis by an equal distance at intervals of 90 degrees around the central axis and extending in the length direction.

As shown in FIG. 11 , the auxiliary toilet seat 30 can be placed vertically with respect to the floor, that is, can be vertically self-supporting. The self-supporting vertical arrangement of the auxiliary toilet seat 30 is realized by having at least three support points at the rear end of the auxiliary toilet seat 30 . That is, a support point 33 a is formed at the rear end of each wing portion 33 , and a support point 31 a is formed at the rear end of the seat portion 31 . When the auxiliary toilet seat 30 is intended to be placed vertically, the left and right support points 33a and the support point 31a arranged on the vertical line passing through the center of the straight line connecting the two points are used to establish a position on the ground. The three points of support forming an isosceles triangle. In the vertical placement state, the center of gravity of the auxiliary toilet seat 30 is set to be arranged above the isosceles triangle formed by the three support points 31a and 33a. As a result, since the auxiliary toilet seat 30 can be vertically placed stably and independently, it is suitable for storage and storage of the auxiliary toilet seat 30 alone.

In addition, the vicinity of the support point 31a and the support point 33a is not flat but formed by a curved surface. Therefore, when the auxiliary toilet seat 30 is viewed from the rear end in a state in which the auxiliary toilet seat 30 is not placed vertically, there are no cold straight lines and plane elements, and a soft aesthetic feeling is felt. In addition, there may be four or more support points. In addition, all support points may be arranged only at the rear end of the seat portion 31 or only at the rear end of the wing portion 33 .

Fig. 12 is a perspective view of the toilet seat fixing part 70 shown in Fig. 10; Fig. 13 is a side view of the toilet seat fixing part 70 shown in Fig. 10 . The toilet seat fixing member 70 has a cylindrical wall portion 71 formed in a cylindrical shape, and a support wall 72 that closes the inside of the cylindrical wall portion 71 . A notch portion 71 a is formed in the upper portion of the cylindrical wall portion 71 by cutting out a portion corresponding to a substantially semicircle. A circular attachment hole 72 a centered on the central axis C of the tubular wall portion 71 is formed in the support wall 72 .

On the peripheral surface of the cylindrical wall portion 71, two fixing protrusions 73a, 73b projecting radially from the central axis C around the central axis C at intervals of 90 degrees are formed in the length direction. . The protrusion amount of the fixing protrusion 73a is larger than the protrusion amount of the fixing protrusion 73b. In addition, four insertion portions 74 are formed at the lower end of the cylindrical wall portion 71 at positions including positions corresponding to the respective fixing protrusions 73a, 73b at 90° around the central axis C. The degree interval is cut into a predetermined depth from the lower end face.

The toilet seat fixing member 70 is attached to the back of the auxiliary toilet seat 30 by inserting the holding member 38 of the auxiliary toilet seat 30 to the side where the insertion portion 74 is formed while checking the posture of the toilet seat fixing member 70 . Inside the cylindrical wall portion 71. That is, the rotation positions around the central axis C are aligned so that the four holding protrusions 39 protruding from the holding member 38 are inserted into the insertion portion 74 of the toilet seat fixing member 70 . In this state, the toilet seat fixing member 70 is fixed to the back surface of the auxiliary toilet seat 30 by inserting screws into the attachment holes 72a and fastening them ( FIG. 10 ). In addition, the toilet seat fixing member 70 is formed by integrally molding hard plastic, such as polypropylene.

FIG. 14 is a diagram showing mounting of the auxiliary toilet seat 30 of FIG. 9 on the general toilet seat 3 . When the auxiliary toilet seat 30 is mounted on the general toilet seat 3 , the urine baffle 32 and the pair of left and right toilet seat fixing members 70 are inserted into the opening 4 of the general toilet seat 3 . The auxiliary toilet seat 30 is fixed to the general toilet seat 3 when the urine baffle 32 inserted into the opening 4 and the toilet seat fixing member 70 strongly abut against the side edge 4 a defining the opening 4 . Specifically, in the urine baffle 32 , the front surface 32 a or the rib member 32 b is in contact with the front side edge 4 a of the opening 4 of the toilet seat 3 . Moreover, in the toilet seat fixing member 70, the outer part in the left-right direction abuts on the left and right side edge parts 4a of the opening part 4 of the toilet seat 3, respectively.

Here, since the size and shape of the opening 4 of the general toilet seat 3 vary depending on the toilet maker, it is necessary to adjust so that the auxiliary toilet seat 30 is securely fixed. FIG. 15 is a diagram showing adjustment of attachment of the toilet seat fixing member 70 of FIG. 10 . The part shown in FIG. 15 is the toilet seat fixing part 70 on the right side in FIG. 14 . In FIG. 15 , the toilet seat 3 for general use is omitted, and only the side edge 4 a of the opening 4 of the toilet seat 3 is shown.

For example, when the opening 4 of the toilet seat 3 is relatively large, the side edge 4 a of the opening 4 is arranged on the right side of the toilet seat fixing member 70 . Therefore, as shown in FIG. 15( a ), the rotational position of the toilet seat fixing member 70 is adjusted so that the fixing protrusion 73 a protruding most radially from the center axis C faces the side edge 4 a. The rotation position of the toilet seat fixing member 70 is adjusted by temporarily loosening the screw inserted into the attachment hole 72a, rotating the toilet seat fixing member 70 around the rotation axis, and then tightening the screw. The rotation axis is an axis extending downward in the mounted state of the auxiliary toilet seat 30 , and is the same as the central axis C of the cylindrical wall portion 71 here.

In addition, when the opening 4 of the toilet seat 3 is small, as shown in FIG. The rotational position of the member 70 is adjusted. In the case where the opening 4 of the toilet seat 3 is smaller, as shown in FIG. 15(c), the fixing protrusions 73a, 73b are not arranged to face the side edge 4a, and the cylindrical wall 71 and the side edge The rotational position of the toilet seat fixing member 70 is adjusted in such a manner that the portions 4a are opposed to each other. When the opening 4 of the toilet seat 3 is further smaller, as shown in FIG. 15( d ), the rotation position of the toilet seat fixing member 70 is adjusted in such a manner that the notch 71 a is arranged to face the side edge 4 a. adjust.

As described above, it can be said that the toilet seat fixing member 70 has a plurality of abutting parts formed so as to be different from the side edge part 4a of the opening part 4 of the toilet seat 3 to be inserted. The toilet seat fixing member 70 is rotated so as to be in contact with the side edge portion 4a. Here, the plurality of contact portions refers to four contact portions of the fixing protrusions 73a and 73b, the cylindrical wall portion 71, and the notch portion 71a.

In FIG. 15 , four adjustment modes for installation of the toilet seat fixing member 70 on the right side in FIG. 14 are described. However, since the left toilet seat fixing member 70 also has four adjustment modes, by adjusting the left and right toilet seat fixing members 70 independently, a total of ten modes of adjustment can be implemented.

According to the adjustment mechanism of the auxiliary toilet seat 30 described above, by changing the rotational position of the toilet seat fixing member 70 around the central axis (rotation axis), despite the difference in size and shape of the opening 4 of the toilet seat 3 , , it is also possible to mount the auxiliary toilet seat 30 on the general toilet seat 3 . In addition, since this adjustment mechanism has fewer parts than the adjustment mechanism described in Patent Document 1, for example, and the shape of each part is relatively simple, it can be manufactured at low cost.

In the adjustment mechanism described above, each toilet seat fixing member has four abutment portions abutting against the side edge portion of the opening, and thus has four fixable rotation positions. However, the adjustment mechanism can also be set to have more than five or less than three abutting parts, and have corresponding rotational positions that can be fixed. In addition, the protrusion amount, shape, etc. of the fixing protrusion can also be set arbitrarily. Furthermore, as long as the plurality of abutting parts have a part that abuts according to the distance between the toilet seat fixing member and the side edge part of the opening, it is also possible, for example, to have the following shape. The shape of this continuous curved surface where the abutting portions of the fixing protrusions are joined together. Moreover, it is also possible to adopt a mode in which the adjustment mechanism does not have the above-mentioned holding protrusion and insertion portion of the adjustment mechanism, but simply inserts the holding member of the auxiliary toilet seat into the cylindrical wall portion of the toilet seat fixing member, and passes the Screws for fixing. In this case, the rotational position is not adjusted stepwise as described above, but can be adjusted steplessly. Therefore, even if focusing on the same fixing protrusion 73a, it can be brought into contact with the side edge portion 4a at an optimal position, angle, etc. by finely adjusting the rotational position steplessly.

FIG. 16 is a perspective view of the lid member 40 of the infant toilet 1 of FIG. 1 ; FIG. 17 is a side view of the lid member 40 of FIG. 16 . The cover member 40 has: a flat top plate 41, which becomes a first step; an edge wall 42, which extends downward from the edge of the top plate in the closed state of the cover member 40; The left and right rear ends extend vertically in the front-rear direction; the reinforcing plate 44 extends between the left and right support plates 43 and reinforces the support plates 43 .

Although not shown, the top plate 41 is the same as the top plate 51 of the auxiliary step member 50 described later with reference to FIG. The part is arranged at a lower position. In the case where the cover member 40 is used as the first step, the step portion realizes an anti-slip effect by catching the feet. In addition, the surface of the top plate 41 is wrinkled for the purpose of anti-slip and design.

The rear part of the edge wall 42 is formed with a notch 42a cut out at about half the length in the longitudinal direction. By forming the notch part 42a, when closing the cover member 40, the possibility that an infant pinches clothes etc. between the cover member 40 and the toilet seat main body 10 is reduced.

Each of the support plates 43 has a hollow boss portion 45 extending outward on the outer side of the support plate 32 and a tooth portion 46 formed concentrically with the boss portion 45 It is ring-shaped and has concave and convex tooth surfaces facing outward.

A concave portion 108 communicating with the holding concave portion 104 via the opening portion 107 is formed on the surface of the inner holding portion 102 opposite to the holding concave portion 104 . The bearing component 100 is formed by integrally molding hard plastic such as polypropylene.

Assembly of the opening and closing mechanism of the cover member 40 will be described with reference to FIG. 18 . The bearing inner member 80 is attached to the support plate 43 of the cover member 40 from the outside. At this time, the protrusion 45 penetrates the circular opening 82 , the opening 86 , and the rectangular opening 83 of the bearing inner member 80 . And, it is attached so that the tooth part 46 of the support plate 43 of the cover member 40 meshes with the tooth part 81 of the bearing inner member 80 . In this state, the spring member 90 is further covered on the outside of the boss portion 45 . One end of the spring member 90 is in contact with the partition wall 85 of the bearing inner member 80 .

Furthermore, the bearing member 100 is attached from the outside while compressing the spring member 90 . At this time, the bearing inner member 80 is housed in the holding recess 104 of the bearing member 100 . The other end of the spring member 90 covers the outer side of the annular protrusion 106 and abuts against the spring support surface 105 . That is, the spring member 90 biases the bearing inner member 80 in the direction of the support plate 43 of the cover member 40, so that the tooth portion 46 of the support plate 43 of the cover member 40 and the tooth portion 81 of the bearing inner member 80 are more reliably realized. engage. Finally, the pin member 110 is inserted from the inside of the support plate 43 of the cover member 40 . The pin member 110 penetrates the inside of the boss portion 45 , and its tip reaches the concave portion 108 of the bearing member 100 . The tip of the pin member 100 is screwed or riveted in the concave portion 108 so as to be fixed so as not to come out.

When the cover member 40 is rotated relative to the bearing member 100, the inclined surfaces of the teeth 46 of the support plate 43 of the cover member 40 and the inclined surfaces of the teeth 81 of the bearing inner member 80 slide against each other, and the bearing inner member 80 overcomes the spring member. 90 to slide in the holding recess 104 in a direction away from the support plate 43 . When the apex of the tooth portion 46 of the cover member 40 passes over the apex of the tooth portion 81 of the bearing inner member 80, the bearing inner member 80 will be slid in the holding recess 104 in the direction of the support plate 43 by the biasing force of the spring member 90, The teeth 46 and 81 will thus mesh again. That is, the tooth portion 46 and the tooth portion 81 are biased in the meshing direction by the spring member 90 . Therefore, the holding recessed portion 104 has at least a depth capable of moving the bearing inner member 80 by a movement distance required for meshing the sliding tooth portion 46 with the tooth portion 81 and releasing the meshing. The frictional force when the inclined surfaces of the teeth 46 of the support plate 43 of the cover member 40 and the inclined surfaces of the teeth 81 of the bearing inner member 80 slide against each other and the biasing force of the spring member 90 act as resistances to the rotation of the cover member 40 .

Here, the spring member 90 is selected so that the tooth portion 46 of the cover member 40 and the inside of the bearing are connected to the rotational torque transmitted to the tooth portion 81 of the bearing inner member 80 through the tooth portion 46 due to the self-weight of the cover member 40 . The engagement of the tooth portion 81 of the member 80 is not released by applying force to such an extent. Therefore, the cover member 40 can be stationary at any rotational position with respect to the bearing member 100 , and can be rotated only when the user applies a force to open and close the cover member 40 . As a result, the closing movement of the cover member 40 is restricted, thereby reducing the possibility of infants being caught in clothes or the like by the cover member 40 .

25 is a perspective view of the auxiliary step member 50 of the toilet for infants and young children in FIG. 1; FIG. 26 is a bottom view of the auxiliary step member 50 of FIG. 25; FIG. 27 is a view of the auxiliary step member 50 of FIG. cutaway view. The near side in FIG. 25 and the upper side in FIG. 26 of the auxiliary step member 50 are arranged on the front side in the two-step state of the infant toilet 1 ( FIG. 5 ).

The auxiliary step member 50 has a flat top plate 51 constituting a second step, and side walls (leg portions) 52 extending downward from the edge of the top plate 51 . The top plate 51 is arranged at a lower position by a step portion 53 having a slight level difference from the upper edge portion of the side wall 52 . When the auxiliary step member 50 is used as a second step, the step portion 53 achieves an anti-slip effect by catching the feet. In addition, the surface of the top plate 51 is wrinkled for the purpose of anti-slip and design. At the center of the back surface of the top plate 51, a pair of claw plates 54 protruding from the back surface and extending in the front-rear direction are formed. Each of the claw plates 54 has claw portions 54 a on the outer surfaces thereof.

The side wall 52 is composed of a flat rear surface 52a, a rearwardly curved front surface 52b, and outwardly curved left and right side surfaces 52c. The front surface 52b is curved backward so that in the state of two steps, it is possible to secure a large area for placing a foot on the top plate 41 of the cover member 40 which is the first step.

A notch 52d having a large width is formed on the lower portion of the rear surface 52a. Likewise, a notch portion 52e having a large width is formed at a lower portion of the front surface 52b. By forming the notch 52d and the notch 52e on the rear surface 52a and the front surface 52b, respectively, the auxiliary step member 50 does not interfere with the cover member 40 in the two-step step state. In other words, the notch 52d and the notch 52e are formed so that the auxiliary step member 50 does not interfere with the lid member 40 , particularly the top plate 41 , but is separated from it when attached to the toilet body 10 . This prevents the top plate 41 and the like of the cover member 40 from being damaged by the auxiliary step member 50 . 52 f of engagement protrusions which engage with the toilet body 10 are formed in the lower end of the left and right side surfaces 52c. The auxiliary step member 50 is formed by integrally molding hard plastic such as polypropylene.

FIG. 28 is a perspective view of the toilet body 10 of the infant toilet 1 in FIG. 1 ; FIG. 29 is a top view of the toilet body 10 in FIG. 28 . The toilet body 10 includes an upper section 11 and a lower section 12 . The lower section 12 is formed as a separate component from the upper section 11 mainly for design purposes, but may be integrally formed with the upper section 11 . The upper section 11 and the lower section 12 are respectively molded from hard plastic, such as polypropylene.

On the upper surface of the toilet main body 10, a recessed portion 13 for a middle tub 20 is formed, which can accommodate the middle tub 20. As shown in FIG. A convex portion 13 a corresponding to the separating convex portion 22 a of the middle tub 20 is formed on the bottom surface of the concave portion 13 for the middle tub. In addition, a rectangular attachment opening 13b is formed on the bottom surface of the recessed portion 13 for the barrel behind the convex portion 13a. When storing the auxiliary step member 50 below the toilet body 10 , the step member 50 is accommodated so that the side of the top plate 51 is downward, that is, turned upside down ( FIG. 3 ). At this time, the claw plate 54 of the auxiliary step member 50 protrudes upward from the attachment opening 13 b of the toilet body 10 , and is snap-engaged with the attachment opening 13 b by the claw portions 54 a of the left and right claw plates 54 . on the left and right side edges 13c. Therefore, when the auxiliary step member 50 accommodated below the toilet body 10 is detached from the toilet body 10, the engagement of the claw plate 54 is released from above the installation opening 13b, thereby Can be detached from the toilet body 10 .

In the vicinity of the periphery of the concave portion 13 for the middle barrel, an annular flat surface 14 is formed in an annular shape and formed flat. A storage hole 14a for storing the toilet seat fixing member 70 attached to the back surface of the auxiliary toilet seat 30 is formed in a wide part of the left and right rear of the annular flat surface 14 . The annular flat surface 14 supports the outer edge portion 23 of the middle tub 20 when the middle tub 20 is housed in the middle tub recess 13 .

Around the ring-shaped flat surface 14 is formed a toilet seat mounting surface 15 which is ring-shaped and flatly formed, and is disposed at a position lower than the ring-shaped flat surface 14 . The toilet seat mounting surface 15 is a mounting surface on which three rubber leg members 60 are arranged when the auxiliary toilet seat 30 is attached to the toilet body 10 . That is, the auxiliary toilet seat 30 is supported by arranging each rubber leg member 60 of the auxiliary toilet seat 30 on the toilet seat mounting surface 15 at a corresponding position.

A U-shaped flat surface 16 is formed around the toilet seat mounting surface 15. The U-shaped flat surface 16 is U-shaped and flatly formed when viewed from the front of the toilet 1 for infants, and is arranged on the On the position higher than the annular flat surface 14 and the toilet seat loading surface 15. The concave portion 16 a surrounded by the U-shaped flat surface 16 and having the annular flat surface 14 and the toilet seat mounting surface 15 as a bottom surface is formed in a shape for accommodating the auxiliary toilet seat 30 .

Restricting walls 17 are formed at the left and right rear outer portions of the U-shaped flat surface 16 . A portion of the U-shaped flat surface 16 in front of the restriction wall 17 is a cover support surface 16 b that supports the lower end surface of the edge wall 42 of the cover member 40 . In addition, the portion near the restriction wall 17 of the U-shaped flat surface 16 is a step support surface 16c that supports the lower end surface of the side wall 52 of the auxiliary step member 50 in a two-step step state. Therefore, the step support surface 16c is not covered even in the closed state of the cover member 40 . In addition, the place where the lower end surface of the side wall 52 of the auxiliary step member 50 is arranged is not limited to the step support surface 16c. For example, it may be another location of the toilet body 10 , or an arrangement location may be provided on the cover member 40 and arranged on the cover member 40 .

The restricting wall 17 restricts the side surface 52 c of the auxiliary stepped member 50 in the two-step stepped state so that the side surface 52 c does not expand in the left-right direction. That is, when an infant climbs on the top plate 51 of the auxiliary step member 50 in the two-step state, the side surface 52c is bent in the left-right direction due to the weight. In order to prevent this bending, a restriction wall 17 is provided. Therefore, the inner surface of the restriction wall 17 is formed in a complementary manner to the side surface 52 c of the auxiliary step member 50 . On the rear part of the U-shaped flat surface 16, recessed parts 16d for accommodating the insertion part 103a of the support branch part 103 of the bearing member 100 are formed on the left and right.

On the rear end surface of the toilet seat main body 10, a bearing recess 18 for arranging the bearing member 100 is formed. Mounting holes 18 b into which the insertion portion 101 a of the bearing member 100 is inserted are formed on the left and right of the bottom surface 18 a of the bearing recess 18 . Furthermore, the front vertical surface of the mounting hole 18b is a rear end surface 18c that abuts against the abutting surface 101b of the bearing member 100 . A mounting recess 19 is formed straddling the U-shaped flat surface 16 and the restricting wall 17 in the left and right rear. A separate step fixing member 120 is installed in the installation recess 19 .

FIG. 30 is a partial enlarged view of the toilet body 10 of FIG. 28 . In addition, FIG. 31 is a perspective view of the step fixing member 120 shown in FIG. 30 . The step fixing member 120 has an L-shaped L-shaped member 121 and a cylindrical shaft portion 122 that match the shapes of the U-shaped flat surface 16 and the restricting wall 17 . The L-shaped member 121 has an engaging protrusion 121a and a pair of engaging claws 121b, wherein the engaging protrusion 121a protrudes laterally inward when mounted on the toilet body 10, and the pair of engaging claws 121b faces downward. extend. The step fixing member 120 is formed by integrally molding hard plastic such as polypropylene.

The step fixing member 120 is pressed into the mounting recess 19 of the toilet body 10 from above, and is engaged with the inside of the toilet body 10 by a pair of engaging claws 121 b to be mounted on the toilet body 10 . Since the shaft portion 122 of the L-shaped member 121 of the step fixing member 120 is supported inside the toilet body 10, it has flexibility in the left-right direction.

When the auxiliary step member 50 is mounted on the toilet body 10, the engaging protrusion 121a of the step fixing member 120 of the toilet main body 10 and the engaging protrusion 52f of the side wall 52 of the auxiliary step member 50 are snap-engaged. At this time, since the step fixing member 120 has flexibility in the left-right direction, smooth attachment of the auxiliary step member 50 can be achieved. When the auxiliary step member 50 is detached from the toilet body 10, by pressing the upper ends of both step members 120 outward, the engagement protrusion 121a of the step fixing member 120 of the toilet body 10 and the auxiliary step member 50 are aligned. The engagement between the engaging protrusions 52f of the side wall 52 is released. In addition, instead of attaching the separate step fixing member 120 to the toilet body 10 , an engaging protrusion may be integrally formed with the restriction wall 17 . In this case, when detaching the auxiliary stepped member 50, it is only necessary to bend the auxiliary stepped member 50 itself and remove it. In addition, by forming the engaging protrusion integrally with the restricting wall 17, the number of parts can be reduced and the cost can be reduced. In the above manner, the auxiliary step member 50 is detachably fixed on the toilet body 10 and is detachably accommodated under the toilet body 10 .

Hereinafter, a modified example of the opening and closing mechanism for not sandwiching the cover member such as infant clothes will be briefly described, focusing on differences from the above-described opening and closing mechanism.

FIG. 32 is a diagram showing a modified example of attachment of the lid member 140 to the toilet body. The cover member 140 has a support plate 143 and a protrusion 145 extending outward from the support plate 143 . In this modified example, torsion springs (elastic members) 190 are used. The torsion spring 190 is covered on the outside of the protrusion 145 . One end of the torsion spring 190 is fixed to the support plate 143, and the other end is fixed to the toilet body side such as a bearing member (not shown). The torsion spring 190 urges the lid member 140 to open. The torsion spring 190 is selected to have such an urging force that the lid member 140 is not completely closed due to the weight of the lid member 140 . As a result, the closing movement of the cover member 140 is restricted, so that the infant is less likely to be caught in clothing or the like by the cover member 140 .

FIG. 33 is a diagram showing the opening operation of the cover member 140 in the modified example of FIG. 32 . According to this modified example, since the cover member 140 is biased in the opening direction by the torsion spring 190 so as not to be completely closed, a mechanism for maintaining the closed state is required. A locking claw 147 is formed, and a locking hole 116a is formed, for example, at the front end portion of the U-shaped flat surface 116 of the toilet body. When the lid member 140 is closed against the elastic force of the torsion spring 190 , the locking claw 147 is locked with the edge portion 116 b of the locking hole 116 a ( FIG. 33( a )). In this state, for example, the button part 150 arranged on the front surface near the locking hole 116a of the toilet body is pushed backward. Thereby, the member near the locking hole 116a of the toilet body is bent ( FIG. 33( b )), the locked state is released, and the lid member 140 is automatically opened.

FIG. 34 is a diagram showing another modified example of attachment of the lid member 240 to the toilet body. The cover member 240 has a support plate 243 and a hollow protrusion 245 extending outward from the support plate 243 . In this modified example, a flexible U-shaped plate-shaped holding member 290 is used. A gear portion 245a is formed on the peripheral surface of the boss portion 245 like a gear. On the curved inner peripheral surface of the holding member 290, a tooth portion 290a complementary to the gear shape of the gear portion 245a is formed. The holding member 290 is arranged to hold the boss 245 . At this time, the gear portion 245 a of the boss portion 245 meshes with the tooth portion 290 a of the holding member 290 . In addition, long holes 290b extending obliquely downward from the inner side toward the outer side are formed on the U-shaped straight line portion on the left and right.

FIG. 35 is a diagram showing the operation of the cover member 240 in the modified example of FIG. 34 . A support rod 200 extending toward the support plate 243 from a bearing member (not shown) is inserted into each elongated hole 290b of the holding member 290 . Furthermore, above the clamping member 290, the clamping plate 201 extending toward the support plate 243 from a bearing member (not shown) and having the same diameter as the protrusion 245 is arranged. By the support rod 200, the deformation of the two ends of the U-shaped clamping member 290 to the separation direction is suppressed, and by the clamping plate 201, the two ends of the U-shaped clamping member 290 are restrained from approaching. direction deformation.

When the lid member 240 is opened and closed, the inclined surface of the gear portion 245a of the protrusion 245 and the tooth portion 290a of the clamping member 290 slide against each other, and the U-shaped clamping member 290 is deformed in a direction in which both ends are separated. (Fig. 35(b)). Moreover, when the opening and closing action continues and the apex of the gear portion 245a of the protrusion 245 passes over the apex of the tooth portion 290a of the clamping member 290, the restoring force of the flexible clamping member 290 makes the gear portion 245a Mesh with the tooth portion 290a again. That is, the gear portion 245 a and the tooth portion 290 a are biased in the meshing direction by the clamping member 290 .

Here, the frictional force when the slope of the gear portion 245a of the boss portion 245 and the tooth portion 290a of the holding member 290 slide against each other and the biasing force generated by the restoring force of the holding member 290 become the rotation of the cover member 240. In terms of resistance. Therefore, the holding member 290 is formed to have a restoring force of such a degree that the cover member 240 is not rotated due to the weight of the cover member 240 and can be stationary at any rotational position. , that is, only such a degree of restoring force that the cover member 240 can be rotated when the user applies force to open and close the cover member 240 . As a result, the closing movement of the cover member 240 is restricted, thereby reducing the possibility of infants being caught in clothes or the like by the cover member 240 .

FIG. 36 is a diagram showing yet another modification example of attachment of the lid member 340 to the toilet body; FIG. 37 is a cross-sectional perspective view showing the internal structure of the modification example of FIG. 36 . The cover member 340 has a support plate 343 and a hollow protrusion 345 extending outward from the support plate 343 . In this modified example, an annular gasket member 300 and a cylindrical elastic member 301 are used. The protrusion 345 has a flat surface 345a on a part of its peripheral surface. Since the washer member 300 fitted on the protrusion 345 has the straight edge portion 300 a complementary to the flat surface 345 a of the protrusion 345 , the washer member 300 also rotates together with the rotation of the cover member 340 . The elastic member 301 is fitted outside the protrusion 345 from the state shown in FIG. 36 , and in this state, the elastic member 301 is pressed into the holding recess 303 formed on the bearing member 302 ( FIG. 37 ).

When the cover member 340 is opened and closed, large friction occurs between the end surface of the gasket member 300 and the end surface of the elastic member 301 and between the outer peripheral surface of the protrusion 345 and the inner peripheral surface of the elastic member 301. . Among these frictions, frictional resistance becomes a resistance to rotation of the cover member 340 . Therefore, in such a manner that the lid member 340 will not rotate due to the weight of the lid member 340 and can be stationary at any position, that is, it can be rotated only when the user applies force to open and close the lid member 340. Adjust the frictional resistance. As a result, the closing movement of the cover member 340 is restricted, thereby reducing the possibility of the infant being caught by the cover member 340 in clothing or the like.

As another modified example of the opening and closing mechanism of the cover member for restricting the closing operation of the cover member so as not to pinch the clothes of infants, for example, a member having a damper function for relieving the rapid opening and closing operation of the cover member may be used. In addition, as long as the clothes are not sandwiched between the cover member and the toilet body, etc., it is also possible to have a position before the cover member is completely closed, for example, a position with a gap of about 5 to 15 mm from the toilet body. Such an institution ceases to exist.
