Forms used to implement the invention

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings, the corresponding constituent elements are marked with common reference numerals.

FIG. 1 is an external perspective view of an infant toilet (small toilet) 1 to which the present invention is applied, FIG. 2 is a diagram showing the installation of main parts of the infant toilet 1 of FIG. 1, and FIG. 3 is an illustration of the toilet 1 of infant 1 Bottom view.

The infant toilet 1 includes a toilet body 10, an inner tub 20, a toilet seat (auxiliary toilet seat) 30 that can be placed on the toilet body 10, a cover member 40 covering the toilet body 10, and an auxiliary step that can be stored below the toilet body 10. Component 50. The cover member 40 is pivotably (ie, switchable) attached to the toilet body 10. In addition, in this specification, the back side (that is, the opened cover member 40 side) when the infant toilet 1 is seated is set to the "rear" side, and the opposite side is set to the "front" side.

Before describing the details of each component, the method of using the infant toilet 1 to which the present invention is applied will be described.

FIG. 4 is a view showing the installation of the auxiliary step member 50 of the toilet 1 of FIG. 1, FIG. 5 is a view showing the two-step stepped state of the toilet 1 of FIG. Diagram of 1st step.

The infant toilet 1 can be used as a general toilet in the first stage of diaper training, as shown in FIG. 1. After that, as young children grow up, they will not be trained as toilets for general use (adults). For children, the opening of the toilet seat is generally too large. If they sit down, they may fall into the toilet. In order to prevent falling, the toilet seat 30 is usually placed on the toilet seat as an auxiliary toilet seat. At this time, the infant can use the cover member 40 and the auxiliary step member 50 as a step before sitting on a toilet seat of a general toilet. (I.e., the lifting platform), or as a step on the foot (i.e., a foothold), so as to facilitate the use of force when using the toilet while sitting face down.

The auxiliary step member 50 can be taken from below the stored toilet body 10 Next, as shown in FIG. 4, it is attached to the upper part of the toilet body 10 from above the cover member 40 in a closed state. As shown in FIG. 5, the toilet 1 for infants and young children equipped with the auxiliary step member 50 can be used as a step platform with two steps. The closed member 40 is used as the first step, and the auxiliary device mounted on the step member The step member 50 serves as a second step. This state is called a two-step ladder state. The two-stage stepped infant toilet 1 is placed on the front of the general toilet 2 with the auxiliary toilet seat 30 installed, so that the infant toilet 1 can be used as a lifting platform and a foothold.

As the child grows older, the auxiliary step member 50 is not required. at this time, The auxiliary step member 50 can be removed from the upper part of the toilet body 10 and stored again under the toilet body 10. As shown in FIG. 6, the infant toilet 1 with the auxiliary stepped member 50 removed can be used as a step with a step, and the cover member 40 in the closed state is used as the first step. This state is called a one-step step state. The 1-step stepped toilet 1 is arranged on the front of the general toilet 2 with the auxiliary toilet seat 30 installed, so that the 1-step toilet 1 can be used as a lifting platform and a foot with a lower step than the 2-step step. Point to use. In addition, the one-step step can be used not only as a foothold when going to the toilet, but also as a foothold when washing hands or brushing teeth on the sink.

As mentioned above, you can choose one step according to the growth of infants State and two steps of the state, so as to adjust the height of the lifting platform and footing to the best.

Next, the components constituting the toilet 1 for infants will be described.

First, from the inside of the toilet body 10 to storing excreta Bucket 20 illustrated. FIG. 7 is a perspective view of the inner tub 20 of the infant toilet 1 of FIG. 1, and FIG. 8 is a side view of the inner tub 20 of FIG. 7. The inner tub 20 is housed in the toilet body 10, and 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 inner tub 20 has a side wall 21 and a bottom wall 22 that separate a space for storing excrement. The upper end of the side wall 21 is bent outward on the entire outer periphery to form an outer edge portion 23. The outer edge portion 23 of the front end portion of the inner tub 20 extends upwards from other portions, and has a notch portion 23a. When the inner tub 20 is removed from the toilet body 10, the portion having the outer edge portion 23 of the notch portion 23a can be held.

The bottom wall 22 is formed with a convex separation convex portion extending in the left-right direction. 22a. The separation convex portion 22 a is formed at the center portion in the longitudinal direction of the inner tub 20 or is located forward. Since the inner tub 20 has the separation convex portion 22a, when the infant is excreted, urine can be stored on the front side of the separation convex portion 22a, and stool can be stored on the rear side of the separation convex portion 22a. In other words, in the inner tub 20, it is possible to prevent urination and feces from being mixed. Therefore, the cleaning of the inner tub 20 will not be troublesome due to the mixing of urine and stool. As a means for preventing mixing of urine and feces, in addition to the convex separation protrusions, a separation wall portion extending from the bottom wall 22 in the left-right direction may be used. In addition, the inner tub 20 may be formed by integrally molding a hard plastic (such as polypropylene).

Fig. 9 is a perspective view of the auxiliary toilet seat 30 of the toilet 1 for infants of Fig. 1, FIG. 10 is a perspective view of the back of the auxiliary toilet seat 30 of FIG. 9. For simplicity of explanation, even when the toilet seat 30 is not used as an auxiliary toilet seat, it is referred to as an auxiliary toilet seat 30.

The auxiliary toilet seat 30 is placed on the toilet body 10, and in FIG. 9 The inner side and the front side in FIG. 10 are arranged on the front side of the infant toilet 1. The auxiliary toilet seat 30 is a toilet seat configured to be placed on a general toilet. The auxiliary toilet seat 30 includes a ring-shaped seat portion (auxiliary toilet seat body) 31, a urine-retaining portion 32 that blocks urine, and a wing portion 33. The seat portion 31, the urine retaining portion 32, and the wing portion 33 can be formed by integrally molding a hard plastic (for example, polypropylene). In addition, the urine retaining portion 32 may be a separate member that is detachable from the seat portion 31.

The seat portion 31 has a seat surface 34 on which a baby sits, and a seat surface 34 The inner peripheral side extends downward to partition the inner wall 36 of the opening portion 35 and the outer edge portion 37 extends downward from the outer peripheral side of the seat surface 34. The front end of the seat surface 34 may form a bulging portion 34 a that is bulged in a spherical shape. A front end side of the inner wall 36 may be formed with a recessed portion 36 a adjacent to the raised portion 34 a and facing forward. The recessed portion 36a of the inner wall 36 extends upward to the inner surface of the raised portion 34a in accordance with the shape of the raised portion 34a, and forms the urine retaining portion 32 together with the inner surface of the raised portion 34a. The front surface 32a of the urine retaining portion 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 front surface 32a are used when being fixed to a general toilet seat.

The wing portion 33 is left and right behind the seat portion 31, and faces left and right from the seat portion 31 The direction is formed prominently. Since the auxiliary toilet seat 30 has a pair of wings 33, the small seat 31 for infants can be stably placed on a general toilet seat. A pair of rubber leg members 60 are mounted on the back of the wing portion 33, and one rubber leg member 60 is mounted on the back of the front end portion of the seat portion 31, for a total of three rubber leg members 60. The purpose of using the rubber foot member 60 is to prevent the auxiliary toilet seat 30 from sliding with the general toilet seat on which it is placed. The rubber foot member 60 may be formed of, for example, a thermoplastic elastomer and fixed with a screw. However, in FIG. 10, one of the rubber leg members 60 of the wing portion 33 is omitted.

A pair of cylindrical protections are formed on the back, left, right and rear of the auxiliary toilet seat 30 The holding member 38 can be attached with a toilet seat fixing member 70 described later. However, one of the holding members 38 is already mounted with the toilet seat fixing member 70. The holding member 38 has four holding protrusions 39 spaced 90 degrees around the center axis, projecting radially from the center axis by the same distance, and extending in the longitudinal direction.

As shown in FIG. 11, the auxiliary toilet seat 30 can be perpendicular to the ground, that is, straight Stand on its own. The separate upright of the auxiliary toilet seat 30 can be achieved by having at least 3 supporting points at the rear end of the auxiliary toilet seat 30. In other words, a support point 33a is formed at the rear end of each wing portion 33, and a support point 31a is formed at the rear end of the seat portion 31. When the auxiliary toilet seat 30 is to be erected, the three support points forming the equilateral triangle on the ground can be established by using the left and right support points 33a and the support points 31a arranged on a vertical line that passes through the center of the line connecting the two points. . In the upright state, the center of gravity of the auxiliary toilet seat 30 is set to be arranged above the two equilateral triangles formed by the three support points 31a and 33a. Therefore, the auxiliary toilet seat 30 can stand stably and stand upright, so it is suitable for storage and storage of the auxiliary toilet seat 30 alone.

The vicinity of the support point 31a and the support point 33a are not each flat, It is formed by curved surfaces. Therefore, even if the rear end of the auxiliary toilet seat 30 is viewed without being upright, there is no icy straight or flat element at all, and a soft beauty can be felt. In addition, the support points may be more than four. Moreover, all the support points may be arranged only at the rear end of the seat portion 31 or the rear end of the wing portion 33.

FIG. 12 is a perspective view of the toilet seat fixing member 70 shown in FIG. 13 is a side view of the toilet seat fixing member 70 of FIG. 10. The toilet seat fixing member 70 includes a cylindrical wall portion 71 formed in a cylindrical shape, and a support wall 72 filled inside the cylindrical wall portion 71. A cutout portion 71a is formed on an upper portion of the cylindrical wall portion 71, and the cutout portion 71a is Cut a portion equivalent to a roughly semicircle. The support wall 72 is formed with a circular mounting hole 72 a centered on the central axis C of the cylindrical tubular wall portion 71.

The cylindrical wall portion 71 is formed on the peripheral surface around the central axis in the longitudinal direction. The two fixed projections 73a and 73b projecting from the center axis C in the radial direction are spaced at 90 degrees from the line C. The amount of protrusion of the fixed protrusion 73a is larger than the amount of protrusion of the fixed protrusion 73b. In addition, four insertion portions 74 are cut into the predetermined depth from the lower end surface of the central axis C at the lower end of the cylindrical wall portion 71 and including the positions corresponding to the respective fixed projections 73a, 73b.

When the toilet seat fixing member 70 is attached to the back of the auxiliary toilet seat 30, While confirming the position of the toilet seat fixing member 70, the holding member 38 of the auxiliary toilet seat 30 is inserted into the cylindrical wall portion 71 on the side where the insertion portion 74 is formed. In other words, the four holding projections 39 protruding from the holding member 38 are inserted into the insertion portion 74 of the toilet seat fixing member 70 while being aligned with the rotational position about the central axis C. In this state, the toilet seat fixing member 70 can be fixed to the back surface of the auxiliary toilet seat 30 by inserting a screw into the mounting hole 72a and tightening it (FIG. 10). The toilet seat fixing member 70 can be formed by integrally molding a hard plastic (for example, polypropylene).

FIG. 14 shows the auxiliary toilet seat 30 of FIG. 9 placed on a general toilet seat 3 Figure. When the auxiliary toilet seat 30 is placed on the general toilet seat 3, the urine retaining portion 32 and a pair of left and right toilet seat fixing members 70 are inserted into the opening portion 4 of the general toilet seat 3. The urine-retaining portion 32 and the toilet seat fixing member 70 that have been inserted into the opening portion 4 abut tightly against the side edge portion 4 a of the opening portion 4, so that the auxiliary toilet seat 30 can be fixed to the general toilet seat 3. Specifically, the urine retaining portion 32 is a front surface 32 a or a rib member 32 b that abuts a side edge portion 4 a in front of the opening portion 4 of the toilet seat 3. Also, the toilet seat The fixing member 70 is in contact with the left and right side edge portions 4 a of the opening portion 4 of the toilet seat 3 at the outer portions in the left-right direction.

Here, the size or shape of the opening 4 of the toilet seat 3 is generally used. Depending on the toilet manufacturer, adjustments must be made to securely secure the auxiliary toilet seat 30. FIG. 15 is a view showing the mounting adjustment of the toilet seat fixing member 70 of FIG. 10. FIG. 15 shows the toilet seat fixing member 70 on the right side in FIG. 14. In FIG. 15, the general toilet seat 3 is omitted, and only the side edge portion 4 a of the opening portion 4 of the toilet seat 3 is shown.

For example, when the opening portion 4 of the toilet seat 3 is large, the opening portion 4 The side edge portion 4 a is arranged on the right side of the toilet seat fixing member 70. Therefore, as shown in FIG. 15 (a), the rotation position of the toilet seat fixing member 70 is adjusted, and the fixing protrusion 73a protruding most radially from the center axis C is arranged to face the side edge portion 4a. The adjustment of the rotation position of the toilet seat fixing member 70 is performed by loosening the screw inserted into the mounting hole 72a, rotating the toilet seat fixing member 70 about the rotation axis, and tightening the screw again. The rotation axis is an axis extending downward in the placed state of the auxiliary toilet seat 30, and is the same as the central axis C of the cylindrical wall portion 71.

When the opening 4 of the toilet seat 3 is small, as shown in FIG. 15 (b), The rotation position of the toilet seat fixing member 70 is adjusted, and the fixing protrusion 73b with a small protruding amount is arranged to face the side edge portion 4a. When the opening portion 4 of the toilet seat 3 is smaller, as shown in FIG. 15 (c), the rotation position of the toilet seat fixing member 70 is adjusted, and the cylindrical wall portion 71 is not arranged to the side edge portion instead of the fixing protrusions 73a and 73b. 4a opposes. When the opening portion 4 of the toilet seat 3 is smaller, as shown in FIG. 15 (d), the rotation position of the toilet seat fixing member 70 is adjusted, and the notch portion 71a is arranged to be in contact with the side edge portion 4a. Opposite.

As described above, the toilet seat fixing member 70 can be said to have a plurality of abutment portions which are formed so that the toilet seat fixing member 70 can follow the distance from the side edge portion 4a of the opening portion 4 of the toilet seat 3 to be inserted It rotates and comes into contact with the side edge portion 4a. Here, the plurality of abutment portions are four abutment portions such as the fixed protrusions 73a and 73b, the cylindrical wall portion 71, and the cutout portion 71a.

FIG. 15 illustrates four adjustment modes for mounting the right-hand toilet seat fixing member 70 in FIG. 14. Since the left-hand 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 10 modes can be adjusted.

According to the adjustment mechanism of the auxiliary toilet seat 30 described above, the rotation position of the toilet seat fixing member 70 about the central axis (rotation axis) can be changed, thereby allowing the auxiliary toilet seat 30 to be placed regardless of the difference in size or shape of the opening portion 4 of the toilet seat 3. On the general toilet seat 3. In addition, compared with the adjustment mechanism described in Patent Document 1, for example, the adjustment mechanism has a smaller number of parts and a simpler shape of each part, and therefore can be manufactured at lower cost.

The above-mentioned adjustment mechanism has four abutment portions that abut on the side edge portion of the opening portion in each toilet seat fixing member, and thus has four fixable rotation positions. However, the adjustment mechanism may also have more than five or less than three abutting portions, and may have a corresponding fixed rotation position. The amount and shape of the fixed protrusions can be arbitrarily set. In addition, as long as the plurality of abutment portions have a portion capable of abutting according to the distance between the toilet seat fixing member and the side edge portion of the opening portion, it may have a shape having a continuous curved surface connecting the abutment portions of the fixing protrusions, for example. . Moreover, the adjustment mechanism may not have the holding of the adjustment mechanism The protrusions and the insertion portions are merely inserted into the cylindrical wall portion of the toilet seat fixing member and fixed with screws. At this time, the rotation position is not adjustable in several steps as described above, but can be adjusted steplessly. Therefore, even if the same fixed protrusion 73a is seen, for example, by finely adjusting the rotation position in steps, it can abut against the side edge portion 4a at an optimal position and angle.

FIG. 16 is a perspective view of the cover member 40 of the infant toilet 1 of FIG. 1, and FIG. 17 is a side view of the cover member 40 of FIG. 16. The cover member 40 has a flat top plate 41 as a first step, an edge wall 42 extending downward from the edge of the top plate when the cover member 40 is closed, and supports arranged at the left and right rear ends of the cover member 40 and extending vertically in the front-rear direction. A plate 43 and a reinforcing plate 44 extending between the left and right supporting plates 43 to reinforce the supporting plate 43.

Although the top plate 41 is not shown in the figure, similar to the top plate 51 of the auxiliary step member 50 described later with reference to FIG. 25, the top plate 41 is arranged in a closed state with a small step from the upper edge of the side wall 42 in a closed state. In the lower position. When the cover member 40 is used as the first step, the step can achieve the effect of catching the foot and preventing slippage. The surface of the top plate 41 is surface-shaped for the purpose of slip prevention and design.

A notch portion 42 a having a notch is formed in the rear portion of the edge wall 42 at about half the length in the longitudinal direction. By forming the cutout portion 42 a, when the cover member 40 is closed, it is possible to reduce the possibility that an infant or the like may pinch clothes between the cover member and the toilet body 10.

Each support plate 43 has a hollow sleeve portion 45 extending outward on its outer side surface, and a tooth portion 46 having a ring shape concentrically with the sleeve portion 45 and having an uneven tooth surface outward.

FIG. 19 is a perspective view of the bearing inner member 80 shown in FIG. 18, and FIG. 20 FIG. 19 is a front view of the bearing inner member 80 of FIG. 19, and FIG. 21 is a cross-sectional view taken along line A-A of the bearing inner member 80 of FIG. 20. The bearing inner member 80 is a cuboid member having a square front and back surfaces. A tooth portion 81 is formed annularly on the front surface of the bearing inner member 80, and the tooth portion 81 is formed with irregularities so as to be complementary to the tooth portion 46 of the cover member 40. A circular opening 82 having a small-diameter circular cross section is formed inside the annular tooth portion 81. On the other hand, a rectangular opening 83 having a square cross-section is formed on the rear surface of the bearing inner member 80. In other words, the rectangular opening portion 83 is separated by the rectangular peripheral wall 84. Although the circular opening portion 82 and the rectangular opening portion 83 are separated by the separation wall 85, they can communicate through the circular opening portion 86 formed in the separation wall 85.

When the switch mechanism of the cover member 40 is combined, the circular opening portion 82 A portion of the plurality of protrusions 47 formed on the outer peripheral surface of the sleeve portion 45 can be accommodated, and the opening portion 86 can be inserted through a portion of the sleeve portion 45 at the front end of the protrusion 47. The rotation of the sleeve portion 45 caused by the opening and closing of the cover member 40 can be supported by the inner peripheral surface of the circular opening portion 82 and the inner peripheral surface of the opening portion 86 through the plurality of protrusions 47. The bearing inner member 80 can be formed by integrally molding a hard plastic (such as polyacetal).

FIG. 22 is a perspective view of the bearing member 100 shown in FIG. 18, and FIG. 23 FIG. 24 is a front view of the bearing member 100 of FIG. 22, and FIG. 24 is a bearing member of FIG. 23. Sectional view of line B-B at 100. The bearing member 100 is attached to the rear part of the toilet body 10, and the right side in FIG. 23 is arranged on the front side of the toilet 1 for infants. The bearing member 100 includes a quadrangular columnar shaft portion 101 and a cylindrical inner holding portion 102 disposed on an upper portion of the shaft portion 101. An insertion portion 101 a is formed on the lower end surface of the shaft portion 101 so as to protrude downward and can be inserted into the toilet body 10. In addition, the front end surface of the shaft portion 101 forms a flat abutment surface 101b that abuts the rear end surface 18c of the toilet body 10 described later. A support bar portion 103 protruding forward is formed on the upper portion of the contact surface 101b. The support bar portion 103 includes an insertion portion 103 a protruding downward and capable of being inserted into the toilet body 10.

The inner holding portion 102 includes a holding recessed portion 104 which receives and holds the bearing inner member 80. The holding recess 104 forms a rectangular shape complementary to the bearing inner member 80. Therefore, the rotation of the bearing inner member 80 relative to the bearing member 100 may be restricted. A spring support surface 105 is formed on the bottom surface 104 a of the holding recess 104. The spring support surface 105 is raised to have a circular end surface, and abuts on and supports one end of the spring member 90.

The spring support surface 105 is formed with an annular convex portion 106 facing the end surface of the sleeve portion 45 of the bearing inner member 80. The spring support surface 105 of a portion surrounded by the ring-shaped convex portion 106 is formed with an opening portion 107 into which the latch member 110 can be inserted. A concave portion 108 communicating with the holding concave portion 104 through the opening portion 107 is formed on the surface opposite to the holding concave portion 104 of the inner holding portion 102. The bearing member 100 may be formed by integrally molding a hard plastic (for example, polypropylene).

The combination of the switching 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 sleeve portion 45 passes through the circular opening portion 82, the opening portion 86, and Rectangular opening 83. The teeth 46 of the support plate 43 of the cover member 40 are engaged with the teeth 81 of the bearing inner member 80. In this state, the spring member 90 is further fitted over the sleeve portion 45. One end of the spring member 90 is in contact with the separation wall 85 of the bearing inner member 80.

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 recessed portion 104 of the bearing member 100. The other end of the spring member 90 is sleeved on the outer side of the annular convex portion 106 and abuts against the spring support surface 105. In other words, the spring member 90 presses the bearing inner member 80 in the direction of the support plate 43 of the cover member 40, so that the teeth 46 of the support plate 43 of the cover member 40 and the teeth 81 of the bearing inner member 80 become more engaged. indeed. Finally, the latch member 110 is inserted from the inside of the support plate 43 of the cover member 40. The latch member 110 penetrates the inside of the sleeve portion 45, and the front end thereof reaches the recessed portion 108 of the bearing member 100. The front end of the latch member 110 can be fixed in the recess 108 without falling off by screws or caulking.

When the cover member 40 is rotated relative to the bearing member 100, the inclined surface of the tooth portion 46 of the support plate 43 of the cover member 40 and the inclined surface of the tooth portion 81 of the bearing inner member 80 slide against each other, so that the bearing inner member 80 resists The pressure is applied to slide in the holding recess 104 in a direction separating from the support plate 43. When the vertex of the tooth portion 46 of the cover member 40 exceeds the vertex of the tooth portion 81 of the bearing inner member 80, the bearing inner member 80 slides in the holding recess 104 in the direction of the support plate 43 by the pressure of the spring member 90. The teeth 46 and the teeth 81 are engaged again. In other words, the teeth portion 46 and the teeth portion 81 are pressed in the meshing direction by the spring member 90. Therefore, the retaining recess 104 has at least a depth at which the bearing inner member 80 can slide, and can provide the engagement of the teeth 46 and the teeth 81 and their release. The required travel distance. The frictional force when the inclined surface of the toothed portion 46 of the support plate 43 of the cover member 40 and the inclined surface of the toothed portion 81 of the bearing inner member 80 slide against each other, or the urging force of the spring member 90 becomes resistance to the rotation of the cover member 40 .

Here, the spring member 90 may optionally have a pressing force, which is relative to the rotation torque transmitted to the tooth portion 81 of the bearing inner member 80 through the tooth portion 46 due to the weight of the cover member 40 itself, without causing the cover member 40 to The meshing between the tooth portion 46 and the tooth portion 81 of the bearing inner member 80 is released. Therefore, the cover member 40 can be stationary at an arbitrary rotation position relative to the bearing member 100, and can be rotated only when the user applies force to open and close the cover member 40. Therefore, the closing operation of the cover member 40 can be restricted, and the possibility that infants and young children can be caught by the cover member 40 due to the cover member 40 can be reduced.

25 is a perspective view of the auxiliary step member 50 of the infant toilet of FIG. 1, FIG. 26 is a bottom view of the auxiliary step member 50 of FIG. 25, and FIG. 27 is a sectional view taken along line C-C of the auxiliary step member 50 of FIG. The front side in FIG. 25 and the upper side in FIG. 26 of the auxiliary step member 50 are disposed on the front side in the two-stage stepped state (FIG. 5) of the infant toilet 1.

The auxiliary step member 50 includes a flat top plate 51 as a second step, and a side wall (leg portion) 52 extending downward from an edge of the top plate 51. The top plate 51 is disposed at a lower position by a step portion 53 having a slight step from the upper edge portion of the side wall 52. When the auxiliary step member 50 is used as the second step, the section 53 can achieve the effect of catching the foot and preventing slipping. In addition, the surface of the top plate 51 may be surface-shaped for the purpose of slip prevention and design. A pair of claw plates 54 are formed at the center of the rear surface of the top plate 51 and protrude from the rear surface and extend in the front-rear direction. Each of the claw plates 54 includes a claw portion 54 a on the outer surface.

The side wall 52 is a flat rear surface 52a and a front surface curved backward. 52b. The left and right side surfaces 52c curved outward. The front surface 52b is bent rearward, whereby a large leg area can be ensured on the top plate 41 of the cover member 40 as the first step in the two-step step.

A notch portion 52d having a large notch is formed below the rear face 52a. Similarly, a notch portion 52e having a large notch is formed in a portion below the front face 52b. The rear surface 52a and the front surface 52b are respectively formed with a notch portion 52d and a notch portion 52e, so that the auxiliary step member 50 does not affect the cover member 40 in a two-step stepped state. In other words, the cutout portion 52d and the cutout portion 52e are formed so that the auxiliary step member 50 does not affect the cover member 40, and particularly does not affect the top plate 41, when the toilet body 10 is mounted. This prevents damage to the top plate 41 and the like of the cover member 40 due to the auxiliary step member 50. Engaging protrusions 52f are formed at the lower ends of the left and right side surfaces 52c to be engaged with the toilet body 10. The auxiliary step member 50 may be formed by integrally molding a hard plastic (for example, polypropylene).

FIG. 28 is a perspective view of the toilet body 10 of the toilet 1 of FIG. 1, and FIG. 29 is a plan view of the toilet body 10 of FIG. 28. The toilet body 10 includes an upper section 11 and a lower section 12. The lower section 12 is mainly formed separately for the purpose of design, but may be integrally formed with the upper section 11. The upper section 11 and the lower section 12 are respectively formed of hard plastic (for example, polypropylene).

The upper surface of the toilet body 10 is formed with a recessed portion 13 for storing an inner tub 20. A convex portion 13 a corresponding to the separation convex portion 22 a of the inner barrel 20 is formed on the bottom surface of the inner barrel concave portion 13. Further, a rectangular mounting opening 13b is formed on the bottom surface of the inner barrel recess 13 behind the convex portion 13a. When the auxiliary step member 50 is stored below the toilet body 10, the step member 50 faces downward with the top plate 51 side, That is, it is stored upside down (FIG. 3). At this time, the claw plate 54 of the auxiliary step member 50 projects upward from the mounting opening portion 13 b of the toilet body 10, and is snap-fitted to the mounting opening portion by the claw portions 54 a of the left and right claw plates 54. The left and right side edges 13c of 13b. Therefore, in a state where the inner tub 20 has been removed from the toilet body 10, the engagement of the claw plate 54 can be released from above the mounting opening 13b, thereby removing the auxiliary stored under the toilet body 10 from the toilet body 10 Step member 50.

An annular and flat surface is formed around the inner barrel recess 13 Annular flat surface 14. The left and right wide portions of the annular flat surface 14 are formed with receiving holes 14 a for receiving a toilet seat fixing member 70 mounted on the back of the auxiliary toilet seat 30. The annular flat surface 14 supports the outer edge portion 23 of the inner tub 20 when the inner tub 20 is received in the inner tub recess 13.

The annular flat surface 14 is formed in a ring shape and is arranged flat around The toilet seat placing surface 15 is located at a position lower than the annular flat surface 14. The toilet seat placing surface 15 is a placement surface on which three rubber foot members 60 are arranged when the auxiliary toilet seat 30 is mounted on the toilet body 10. In other words, the toilet seat placing surface 15 supports the auxiliary toilet seat 30 by arranging each rubber leg member 60 of the auxiliary toilet seat 30 on the toilet seat placing surface 15 at a corresponding position.

A U-shaped flat surface 16 is formed around the toilet seat placing surface 15, U The flat flat surface 16 is U-shaped and flat when viewed from the front of the infant toilet 1, and is arranged at a position higher than the annular flat surface 14 and the toilet seat placing surface 15. The recessed portion 16 a surrounded by the U-shaped flat surface 16 and having the annular flat surface 14 and the toilet seat placing surface 15 as the bottom surface forms a shape that can accommodate the auxiliary toilet seat 30.

U-shaped flat surface 16 is formed with outer portions on the left and right rear Restriction wall 17. A portion of the U-shaped flat surface 16 that is forward of the restricting 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. The portion near the restricting wall 17 of the U-shaped flat surface 16 is a stepped support surface 16c that supports the lower end surface of the side wall 52 of the auxiliary step member 50 in a two-step stepped state. Therefore, the stepped support surface 16c is not covered even in the closed state of the cover member 40. However, 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 arranged elsewhere in the toilet body 10, or a place may be provided on the cover member 40 and placed thereon.

The restriction wall 17 can restrict the side surface 52c of the auxiliary step member 50 so as not to expand outward in the left-right direction in the two-step step state. In other words, when the infant stands on the top plate 51 of the auxiliary step member 50 in the two-step step state, the side surface 52c is deformed in the left-right direction due to the weight. To prevent this deformation, a restriction wall 17 is provided. Therefore, the inner surface of the restriction wall 17 is formed to be complementary to the side surface 52 c of the auxiliary step member 50. In the rear part of the U-shaped flat surface 16, a recessed portion 16d is formed on the left and right sides to receive the insertion portion 103a of the support bar portion 103 of the bearing member 100.

A bearing recess 18 for arranging the bearing member 100 is formed on the rear end surface of the toilet body 10. Mounting holes 18 b are formed on the bottom surface 18 a of the bearing recess 18 to the left and right of the insertion portion 101 a of the bearing member 100. The front vertical surface of the mounting hole 18 b is a rear end surface 18 c that is in contact with the contact surface 101 b of the bearing member 100. Mounting recesses 19 are formed across the U-shaped flat surface 16 and the restricting wall 17 on the left and right rear sides. The mounting recess 19 can mount a separate stepped fixing member 120.

FIG. 30 is a partially enlarged view of the toilet body 10 of FIG. 28. FIG. 31 is a perspective view of the step fixing member 120 shown in FIG. 30. Ladder fixing member 120 includes an L-shaped member 121 and a cylindrical shaft portion 122 that are L-shaped and that fit the U-shaped flat surface 16 and the restricting wall 17. The L-shaped member 121 includes an engaging protrusion 121 a protruding inward in the lateral direction when the L-shaped member 121 is attached to the toilet body 10, and a pair of engaging claws 121 b extending downward. The step fixing member 120 may be formed by integrally molding a hard plastic (for example, polypropylene).

The step-fixing member 120 is a mechanism for pressing the toilet body 10 from above. The recess 19 is attached, and a pair of engaging claws 121 b is engaged with the inside of the toilet body 10, so that it can be mounted on the toilet body 10. The L-shaped member 121 of the stepped fixing member 120 is supported by the shaft portion 122 inside the toilet body 10, and therefore has flexibility in the left-right direction.

When the auxiliary step member 50 is mounted on the toilet body 10, the toilet The engaging protrusion 121 a of the step fixing member 120 of the main body 10 and the engaging protrusion 52 f of the side wall 52 of the auxiliary step member 50 are engaged with each other in a fast-closing manner. At this time, since the step fixing member 120 has flexibility in the left-right direction, smooth mounting of the auxiliary step member 50 can be performed. When the auxiliary step member 50 is to be removed from the toilet body 10, by pressing the upper ends of the two step fixing members 120 to the outside, the engaging protrusion 121a of the step fixing member 120 of the toilet body 10 and the auxiliary step can be pressed. The engagement of the engagement protrusion 52f of the side wall 52 of the member 50 is released. Alternatively, instead of attaching the separate stepped fixing member 120 to the toilet body 10, the engaging protrusion may be formed integrally with the restricting wall 17. At this time, when the auxiliary step member 50 is to be removed, it is sufficient to remove the auxiliary step member 50 by bending it. In addition, by forming the engaging protrusions integrally with the restricting wall 17, the number of parts can be reduced, and the cost can be further reduced. Above, the auxiliary step member 50 is detachably fixed to the toilet body 10 and is detachably received. Received under the toilet body 10.

In the following, the differences from the above-mentioned switching mechanism will be mainly used, which is simple Several modifications of the switching mechanism for covering members such as clothes and clothing for infants will not be described in detail.

Fig. 32 is a view showing a modification in which the cover member 140 is attached to the toilet body; Case of the figure. The cover member 140 includes a support plate 143 and a sleeve portion 145 extending outward from the support plate 143. In this modification, a torsion spring (elastic member) 190 is used. The torsion spring 190 is sleeved on the outer side of the sleeve portion 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 presses the cover member 140 in an opening direction. The torsion spring 190 may optionally have a pressing force that does not completely close the cover member 140 due to the weight of the cover member 140 itself. Therefore, the closing action of the cover member 140 can be restricted, and there is a low possibility that infants and young children will be caught by the cover member 140 with clothes.

FIG. 33 shows an opening operation of the cover member 140 according to a modification of FIG. 32. Figure. According to the present modification, the cover member 140 is not closed at all by being pressed in the opening direction by the torsion spring 190, so a mechanism for maintaining the closed state is required. Therefore, a locking claw 147 is formed under the front end portion of the cover member 140, and a locking hole 116a is formed at the front end portion of the U-shaped flat surface 116 of the toilet body, for example. When the lid member 140 is closed against the biasing force of the torsion spring 190, the locking claw 147 and the edge portion 116b of the locking hole 116a are locked (FIG. 33 (a)). In this state, for example, the button portion 150 disposed near the front of the locking hole 116a of the toilet body is pressed backward. As a result, the member near the locking hole 116a of the toilet body is deformed (FIG. 33 (b)), the locking state is released, and the cover member 140 is automatically To open.

FIG. 34 is another view showing attachment of the cover member 240 to the toilet body Illustration of the modification. The cover member 240 includes a support plate 243 and a hollow sleeve portion 245 extending outward from the support plate 243. In this modification, a flexible U-shaped plate-shaped holding member 290 is used. A gear portion 245 a is formed on the peripheral surface of the sleeve portion 245 like a gear. A toothed portion 290a complementary to the gear shape of the gear portion 245a is formed on the curved inner peripheral surface of the clamping member 290. The clamping member 290 is configured to be able to clamp the sleeve portion 245. At this time, the gear portion 245a of the sleeve portion 245 and the tooth portion 290a of the holding member 290 are meshed. In the U-shaped straight portion, long holes 290b extending obliquely downward from the inside to the outside are formed on the left and right.

FIG. 35 is a diagram showing the operation of the cover member 240 according to a modification of FIG. 34. Each of the long holes 290b of the clamping member 290 is inserted into a support rod 200 extending from a bearing member (not shown) toward the support plate 243. A clamping plate 201 having the same diameter as the sleeve portion 245 extending from a bearing member (not shown) toward the support plate 243 is disposed above the clamping member 290. With the support bar 200, deformation in the direction in which both ends of the U-shaped clamping member 290 are opened can be suppressed, and with the clamping plate 201, the direction in which both ends of the U-shaped clamping member 290 are approached can be suppressed. Of deformation.

When the cover member 240 is opened and closed, the gear portion 245a of the sleeve portion 245 The inclined surface and the tooth portion 290a of the holding member 290 slide against each other, and the U-shaped holding member 290 is deformed in a direction in which both end portions are opened (FIG. 35 (b)). When the switching operation is continued so that the apex of the gear portion 245a of the sleeve portion 245 exceeds the apex of the tooth portion 290a of the clamping member 290, the gear portion 245a and the tooth portion 290a will be restored by the restoring force of the flexible clamping member 290. Bite again. In other words, the gear portion 245a and the tooth portion 290a are pressed in the meshing direction by the clamping member 290.

Here, the frictional force when the inclined surface of the gear portion 245 a of the sleeve portion 245 and the tooth portion 290 a of the holding member 290 slide against each other or the pressing force generated by the restoring force of the holding member 290 becomes the cover member 240 Resistance to rotation. Therefore, the clamping member 290 has a cover member 240 that does not rotate due to the weight of the cover member 240 itself, and can be stationary at any rotation position, that is, it can be rotated and restored only when the user applies force to open and close the cover member 240. force. Therefore, the closing action of the cover member 240 can be restricted, and the possibility that infants are caught by the cover member 240 to clothes or the like can be reduced.

FIG. 36 is a view showing still another modified example of attaching the cover member 340 to the toilet body, and FIG. 37 is a sectional perspective view showing the internal structure of the modified example of FIG. 36. The cover member 340 includes a support plate 343 and a hollow sleeve portion 345 extending outward from the support plate 343. In this modification, an annular gasket member 300 and a cylindrical elastic member 301 are used. The sleeve portion 345 has a flat surface 345a on a part of its peripheral surface. Since the gasket member 300 embedded in the sleeve portion 345 has a straight edge portion 300 a that is complementary to the flat surface 345 a of the sleeve portion 345, the gasket member 300 also rotates as the cover member 340 rotates. From the state shown in FIG. 36, the elastic member 301 is fitted into the outer side of the sleeve portion 345, and in this state, the elastic member 301 is further pressed into the holding recess 303 formed in 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 sleeve portion 345 and the inner peripheral surface of the elastic member 301. These frictional frictional resistances become resistances against the rotation of the cover member 340. Therefore, these frictional resistances can be adjusted so that the cover member 340 does not rotate due to the weight of the cover member 340 itself, And it can be stationary in any rotation position, that is, it can be rotated only when the user applies force to open and close the cover member 340. As a result, the closing operation of the cover member 340 can be restricted, and the possibility that infants are caught by clothes by the cover member 340 can be reduced.

Restrict the closing action of the lid member to avoid getting caught in infants' clothes As another modification example of the switching mechanism of the cover member, for example, a member having a damping function that mitigates the sudden opening and closing operation of the cover member can be used. In addition, as long as clothes and the like are not caught between the last cover member and the toilet body, it can also have a position before the cover member is completely closed, for example, leaving a gap of about 5-15 mm from the toilet body. Position to stop the mechanical mechanism.
