DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an example of a toilet bowl for a baby to which the present invention is applied. 1 is a perspective view, FIG. 2A is a top view, FIG. 2B is a bottom view, and FIG. 3 is a cross-sectional view taken along line AA in FIG.
[0012]
The toilet bowl 1 is housed below the main body 2, the inner lid 3, the toilet seat (auxiliary toilet seat) 4 placed on the main body 2, the lid 5 covering the opening of the toilet seat 4, and the main body 2. And a board (tread board) 6.
[0013]
The main body 2 includes an upper step portion 11 and a lower step portion 12. As shown particularly in FIG. 3, the upper step portion 11 has a recess portion 11b having an opening portion 11a on the upper side, and a wall portion 11d extending downward from the edge portion 11c of the recess portion 11b so as to surround the recess portion 11b. The lower step portion 12 is continuous with the wall portion 11d so as to be joined to the wall portion 12d, the wall portion 12c extending inward from the lower end portion 12b of the wall portion 12a, and the wall portion 12c. And a ceiling portion 12d. An opening 12e into which the concave portion 11b can be inserted is provided in the ceiling portion 12d, and the upper step portion 11 and the upper step portion 12 are joined in a state where the concave portion 11b is inserted into the opening portion 12e. The upper step portion 11 and the upper step portion 12 are formed, for example, by molding a hard plastic, and the upper step portion 11 and the upper step portion 12 are joined by welding.
[0014]
The recess 11b is formed so as to be able to accommodate the intermediate collar 3. The edge 11c is formed so that the toilet seat 4 can be placed thereon. The lower end 12 b functions as a leg of the main body 2. The storage space 13 surrounded by the wall portion 12c, the ceiling portion 12d, and the bottom portion 11e of the concave portion 11b has a size capable of storing the step plate 6.
[0015]
The left and right side walls of the main body 2 retreat in the left-right direction over the entire height in the central portion 2c from the front end portion 2a and the rear end portion 2b, so that the width of the central portion 2c is larger than the widths of both end portions 2a, 2b. It is set narrowly. Generally, when the toilet seat 4 can be used as an auxiliary toilet seat, the minimum width of the toilet seat 4 is determined because it is necessary to use the toilet seat 4 by placing it on an adult (general) toilet seat. Next, the width of the main body 2 is also determined in accordance with the width of the toilet seat 4. When an infant sits on the toilet bowl 1 having the width determined in this way, the infant's foot is greatly opened, and there is a disadvantage that it is difficult to apply force. However, in the toilet bowl 1, the planar shape is a gourd shape, so that a sufficient width for stably placing the toilet seat 4 is secured at both end portions 2 a and 2 b, while the seated infant is on the foot. It is possible to secure a space for attracting the center portion 2c. Therefore, the infant can be seated in a posture that is easy to force and defecate. Further, the toilet seat 4 is also set so that the width of the central portion 4c is narrower than the front end portion 4a and the rear end portion 4b. Thereby, while ensuring the sufficient width | variety in both ends 4a and 4b so that the toilet seat 4 can be stably mounted in the toilet seat or main body 2 for adults, on the other hand, the infant seated on the toilet 1 It is possible to easily attract the foot to the central portion 2c. In addition, you may set the magnitude | size of center part 2c, 4c suitably.
[0016]
4 to 6 are views showing the toilet seat 4 removed from the main body 2. FIG. 4 is a perspective view, FIG. 5 (a) is a top view, FIG. 5 (b) is a bottom view, and FIG. 6 is a front view. is there. The toilet seat 4 is configured as an auxiliary toilet seat that can also be installed in an adult toilet bowl, and includes a seat portion 20 (auxiliary toilet seat body), a small water receiver 21, and a handle 22 for catching a seated infant. . The seat portion 20 and the small water receiver 21 are integrally formed, and are formed, for example, by integrally molding a hard plastic. The small water receiver 21 may be detachable from the seat portion 20.
[0017]
The seat 20 has an opening 23, side edges 24 and 24 extending in the front-rear direction around the opening 23, a front edge 25 connecting the front ends of the side edges 24 and 24, and the side edges 24 and 24. And a rear edge portion 26 connecting the rear ends of the two. On the outer periphery of each edge 24 to 26, a seating surface 20a is provided continuously to each edge 24 to 26, and below each edge 24 to 26 is vertically connected to each edge 24 to 26. A wall portion 20b extending in the direction is provided.
[0018]
As shown in FIG. 5, the side edges 24, 24 are formed in a straight line parallel to each other, and the front edge 25 is formed in a curved line. However, chamfering is performed at a joint portion between the side edge portion 24 and the front edge portion 25 indicated by a point P1. In the present embodiment, since the side edge portions 24 are set in parallel, the width D1 of the front edge portion 25 is equal to the interval between the side edge portions 24. The interval between the side edge portions 24 is empirically determined based on, for example, a standard physique of an infant. The side edges 24 may be curved or not parallel. The leading edge 25 may be a straight line.
[0019]
A small water receiver 21 is provided in front of the front edge 24. As shown in FIG. 6, the small water receiver 21 is formed in a trapezoidal shape when viewed from the front, and is provided so as to protrude from the seating surface 20a. However, chamfering is performed at the joint portion between the small water receiver 21 and the seat surface 20a indicated by the point P2.
[0020]
In the toilet seat 1, the width D 2 of the small water receiver 21 is narrower than the width D 1 of the front edge portion 24. For this reason, the infant seated on the seat part 20 can put out a foot forward. In other words, among the areas where the small water receivers 21 are conventionally provided, the area R1 indicated by hatching in FIG. 4 can be newly used as a place for placing the thigh. Therefore, the infant is easy to work and has a posture that facilitates defecation. Further, since the joint portion between the small water receiver 21 and the seat surface 20a is chamfered, the joint portion fits the infant's thigh, and the infant comfortably attaches the thigh to the small water receiver. Can do.
[0021]
As shown in FIG. 5B, a recess 21 a for receiving small water is provided on the opening 22 side of the small water receiver 21. Thereby, scattering of the small water which collided with the small water receptacle to the left and right is prevented, and the width of the small water receptacle can be further reduced. Moreover, the recessed part 21a is formed so that it may become deep ahead toward the lower part, and also prevents scattering of small water upwards. In addition, the recessed part 21a is formed so that the width D3 of the recessed part 21a is narrower than the width D2 of the small water receiver 21.
[0022]
The handle 22 is formed in a substantially T shape, and has a horizontal portion 22a and a vertical portion 22b. By making the handle 22 T-shaped, a large space is secured below the horizontal portion 22a, so that the infant can easily bring the thigh to the small water receiver. Further, the horizontal portion 22a is formed to warp upward so as to become higher on both sides, making it easier to bring the thigh to the small water receiver. The handle 22 is attached by fitting the vertical portion 22b into a hole provided in the upper portion of the small water receiver 21, and the user can freely attach and detach it. Therefore, it can be removed and used according to the growth of the infant.
[0023]
As shown in FIG. 5 (b), leg portions 31... 31 and fixing portions 32, 32 are provided on the back side of the seat portion 20. The leg portions 31 ... 31 are provided at the four corners of the seat portion 20, and support the seat portion 20 when the seat portion 20 is placed on the main body 2 or an adult toilet seat. In addition, you may provide the hole which fits the leg part 31 in the main body 2. FIG. The fixing parts 32, 32 are provided one by one on the left and right behind the seat part 20, and are used to fix the seat part 20 to an adult toilet seat.
[0024]
7 and 8 are enlarged views of the fixing portion 32. FIG. 7 corresponds to the outside of the toilet seat 4, and the left side corresponds to the inside of the toilet seat 4 (opening 22 side). The fixed portion 32 includes rails 41, 41, a limit shaft 42, and a stopper member 43.
[0025]
The rails 41 and 41 are formed as vertical walls parallel to each other, and the end portions 41 a and 41 a extend in the lateral direction of the seat portion 20. On the inner wall 41b of the rails 41, 41, convex teeth 41c... 41c that are long in the vertical direction are arranged in the lateral direction of the seat portion 20, and a comb-like fitting portion 41d is formed. The rails 41 and 41 are molded from, for example, hard plastic, and are fixed to the seat portion 20 by welding or the like.
[0026]
The limiting shaft 42 is provided between the rails 41 and 41 and extends vertically downward. The inside of the limiting shaft 42 is hollow and can be used as a female screw. The limiting shaft 42 is molded from, for example, hard plastic, and is fixed to the seat portion 20 by welding or the like.
[0027]
The stopper member 43 includes a wall portion 44 formed in a cylindrical shape, a support portion 45 that closes an upper opening portion of the wall portion 44, and insertion portions 46 and 46 provided above the support portion 45. The wall portion 44 is provided with a notch 44 a on the lower inner side of the seat portion 20, and is formed in a substantially L shape when viewed from the front-rear direction of the seat portion 20. The toilet seat 4 is fixed with the wall portion 44 on the opposite side of the notch 44a contacting the side edge of the adult toilet seat 100 (see FIG. 10B). Further, the wall portion 44 is formed so that the tubular cross-sectional shape is an ellipse whose major axis is the lateral direction of the seat portion 20. The support portion 45 is formed in a plate shape wider than the interval between the rails 41 and 41, and supports both the rails 41 and 41. Further, a long hole 45 a into which the limiting shaft 42 can be inserted is formed at the center of the support portion 45 so as to extend in the lateral direction of the seat surface 20. Therefore, the movement of the stopper member 43 in the lateral direction is limited to a range in which the limiting shaft 42 can move in the long hole 45a. The insertion portions 46 and 46 are formed as vertical walls parallel to each other across the long hole 45a, and when the insertion portions 46 and 46 are inserted between the rails 41 and 41, the outer walls 46a and 46a of the insertion portions 46 and 46 are inserted. And the inner walls 41b and 41b of the rails 41 and 41 are provided at intervals such that they contact each other. On the outer wall 46a, convex teeth 46b... 46b that are long in the vertical direction are arranged in the lateral direction of the seat 20, and a comb-like fitting portion 46c is formed. The fitting portion 46c is formed so as to fit with the fitting portion 41d. The stopper member 43 is formed, for example, by integrally molding a hard plastic.
[0028]
As shown in FIG. 9, the stopper member 43 is attached by a coil spring 47, a washer 48, and a screw 49 in a state where the limiting shaft 42 is inserted into the long hole 45a. The coil spring 47 is attached so that the limiting shaft 42 is inserted into the hollow portion. The coil spring 47 has a diameter longer than the short axis of the long hole 45a and can support the stopper member 43 at the upper end. The lower end of the coil spring 47 is supported by a washer 48 wider than the cross section of the coil spring 47 and is held in a compressed state. The washer 48 is fixed by a screw 49 inserted into the hollow portion of the limiting shaft 42.
[0029]
FIG. 9 and FIG. 10 show the use state when the toilet seat 4 is fixed to the adult toilet seat by the fixing portion 32 as described above.
[0030]
In FIG. 9A, the limiting shaft 42 is in contact with the outside (the right side in the drawing) of the long hole 45 a, and the stopper member 43 is fixed to the innermost side of the toilet seat 4. As shown in this figure, the stopper member 43 is pressed against the rail 41 by a coil spring 47. For this reason, the fitting part 46c and the fitting part 41d mesh, and the movement of the stopper member 43 in the left-right direction is restricted.
[0031]
When the stopper member 43 is moved to the right from the state of FIG. 9A, the stopper member 43 is moved downward as shown in FIG. 9B. Thereby, the fitting part 46c and the fitting part 41d are disengaged, and the stopper member 43 can be moved in the left-right direction. FIG. 10A shows a state where the stopper member 43 is moved to the rightmost side. If the force pulling the stopper member 43 downward is weakened from this state, the stopper member 43 is pressed against the rail 41 by the coil spring 47, the fitting portion 46c and the fitting portion 41d are engaged, and the stopper member 43 is located on the rightmost side. It is fixed at the position moved to. The same applies to the case where the stopper member 43 is moved to the left side, and it is possible to adjust the stopper member 43 to an appropriate position in accordance with the size and shape of the adult toilet seat.
[0032]
When the stopper member 43 is fixed with a screw, the screw must be loosened or tightened to adjust the position of the stopper member 43, which is troublesome. However, according to the fixing portion 32, the position of the stopper member 43 can be easily adjusted according to the size and shape of the adult toilet seat on which the toilet seat 4 is placed. In general, a force is applied to the stopper member from the outer peripheral side of the seat portion 20 to the inner peripheral side. For example, when the stopper member is configured to move in the rotational direction, the stopper member is applied to the arrangement direction of the tooth portion and the stopper member. Since the direction of the force is different, only the tooth portion meshing along the direction from the outer peripheral side to the inner peripheral side among the plurality of tooth portions meshing with each other receives the force received by the stopper member. For this reason, the problem that the intensity | strength of each tooth | gear part must be made high arises. However, in the toilet seat 4 of the present invention, the stopper member 43 is configured to be linearly movable between the inner peripheral side and the outer peripheral side, and the tooth portions 46b... 46b, 41c. Since it is arranged along the direction from the inner circumferential side to the inner circumferential side, it is possible to receive the force received by the stopper member 43 at all of the tooth portions meshing with each other, and the above-described disadvantages can be solved.
[0033]
Note that the number of the fixing portions 32 is not limited to two and may be three or more. The fitting part 46c and the fitting part 41d are not limited to the above-mentioned comb-shaped ones, and appropriate ones can be used. For example, as shown in FIG. 11 (a), the outer wall 46a is provided with shafts 50, 50 extending in the direction perpendicular to the paper surface as tooth portions, and a plurality of slits 51 ... 51 into which the shafts 50 are fitted. The fitting member 53 in which the portions 52... 52 are arranged may be provided on the inner wall 41b. As shown in FIG. 11 (b), tooth portions 54... 54 and tooth portions 55... 55 are arranged on the rail 41 side of the support portion 45 and the end portion 41 a of the rail 41, respectively. 56 and 57 may be formed.
[0034]
The step plate 6 shown in FIGS. 2B and 3 is placed on the main body 2 instead of the toilet seat 4 and covers the opening 11a of the main body 2 so that the toilet 1 can be used as a step. .
[0035]
The step plate 6 is stored upside down in the storage space 13 below the main body 2 when not used. Claw portions 61 and 61 for holding the step plate 6 in the main body 2 are provided at the center of the step plate 6 so as to protrude from the back side (upper side in FIG. 3).
[0036]
12 (a) and 12 (b) are diagrams showing the claw portions 61 and 61 in an enlarged manner. The claw portions 61 and 61 are configured as vertical walls parallel to each other, and are provided to face each other in the front-rear direction. Convex portions 61 a and 61 a that protrude outward are provided on the upper portions of the claw portions 61 and 61. On the other hand, a recess 62 is provided in the center of the bottom 11 e of the upper stage 11. An opening 63 serving as a recess for receiving the claw portions 61, 61 is provided at the bottom 62 a of the recess 62. The opening 63 is formed in a rectangular shape, and the front edge 62 b and the rear edge 62 c around the opening 63 are provided so as to extend in the lateral direction of the main body 2. The distance between the front edge portion 62b and the rear edge portion 62c is equal to the distance between the outer walls of the claw portions 61 and 61, and the width of the opening 63 is equal to the width of the claw portions 61 and 61. Therefore, by inserting the claw portions 61, 61 into the opening 63 until the convex portions 61a, 61a are located above the bottom portion 62a, and hooking the convex portions 61a, 61a to the front edge portion 62b and the rear edge portion 62c, The step plate 6 can be securely held on the main body 2. Since the front edge portion 62b and the rear edge portion 62c are provided in the concave portion 62, the upper portions of the claw portions 61 and 61 protruding upward from the bottom portion 62a do not come into contact with the intermediate collar 3.
[0037]
The opening 63 passes through the main body 2. Therefore, when removing the step plate 6 from the main body 2, simply remove the toilet seat 4 and the inner collar 3 from the main body 2 and push between the claws 61 and 61 as shown by the arrow y1 in FIG. Good. The lower part of the convex portions 61a, 61a is pushed inward by the front edge portion 62b and the rear edge portion 62c, and the claw portions 61, 61 are tilted inward as indicated by arrows y2, y2, whereby the step plate 6 is removed from the main body 2. Detachable.
[0038]
In addition, as shown in FIG.12 (c), the inclination of the lower part of convex part 61a, 61a is tightened with respect to an up-down direction, and the upper end of nail | claw part 61,61 is pushed inward as shown by arrow y3, and it removes from the main body 2. You may do it.
[0039]
By covering the opening of the main body 2 with the step plate 5, for example, when the toilet seat 4 is placed on an adult toilet seat and used as an auxiliary toilet seat, the toilet 1 is used as a step for an infant to get on and off the toilet seat 4. Is available. Further, the toilet 1 can be used as a step for placing the ankle while sitting. Usually, it is necessary to arrange two steps on the left and right of the adult toilet, corresponding to the left and right feet, in order to place the ankle while sitting. However, in the toilet seat 4 of the present embodiment, it is possible to sit with the foot closed in the front, and therefore, the step only needs to be placed at one place in the front. Therefore, the toilet 1 has an advantage that it is not necessary to prepare other steps separately from the steps using the toilet 1. Note that the claw portion may be provided on the bottom surface 11 e of the main body 2, and the hook portion that is hooked on the claw portion may be provided on the back side of the step plate 6.
[0040]
【The invention's effect】
As described above, according to the present invention, the footboard can be reliably held on the toilet body by engaging the claw portion and the hook portion. Moreover, when removing, it is only necessary to disengage the claw portion and the hook portion, and the removal is easy.
