Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infant holding device equipped with a holding stand which is mounted in a manner such as a waist bag and which forms a seating surface for receiving the buttocks of an infant, and more particularly relates to stabilizing the posture of an infant. The present invention relates to an improvement for the purpose.

[0002]

2. Description of the Related Art An infant holding device which is of interest to the present invention is described in, for example, Japanese Utility Model Publication No. 4-46619. The infant holding device includes a holding base forming a seat for receiving the buttocks of the infant, and the holding base is attached to a waist belt worn around a wearer's waist. Also,
This infant retainer is provided with a hand strap that extends from the front part of the seat surface, and by holding the wrist of the wearer while lifting the wrist strap, the infant retainer is prevented from falling. It is designed to be able to hold infants in a preventive and stable manner.

[0003]

However, in order to realize a state in which the infant can be prevented from falling and the infant can be stably held by using the above-mentioned wrist strap, the wrist strap should be worn on the wrist strap. You must keep it lifted up. This is because the handle band is not self-supporting and therefore cannot support the infant without the help of the wearer.

As a result, one hand of the wearer is always restrained by the hand strap, and the wearer cannot use both hands freely while holding the baby. Also, since the hand strap can be deformed relatively easily in any direction,
Depending on the position of the wearer's hand, the baby may be forced into an unnatural posture. Therefore, an object of the present invention is to provide an infant holding device capable of solving the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a waist belt worn around the waist of a wearer and a seating surface for receiving the buttocks of an infant, which is attached to and worn by the waist belt. In order to solve the above-mentioned technical problem, a pad wall that stands up from a seat surface is provided for a baby holding device, which is provided with a holding table that is positioned so as to project from the lower abdomen of the person. Is provided.

[0006]

According to the present invention, since the pad wall is provided so as to stand up from the seat surface, it is possible to prevent the baby's buttocks from shifting on the seat surface, and therefore the baby falls from the holding table. Can be prevented. Further, since the pad wall can be provided with independence by being loaded with a core material having sufficient rigidity, the pad wall exhibits the above-mentioned functions without the help of the wearer. . Therefore, the wearer can use both hands freely, and for example, a danger can be quickly dealt with and safety can be enhanced.

Further, the existence of the pad wall can prevent the infant's spine from being bent abnormally and can always keep the infant's posture normal. Therefore, it is possible to provide an infant holder that can contribute to the health of the infant. In the present invention, preferably, the pad wall is rotatably attached to the holding base so that the pad wall can be selectively extended between the seat surface and the seat surface. With such a configuration, when the baby is not placed on the holding table, the pad wall is made to extend along the seat surface, whereby the bulk of the baby holder can be reduced, and the baby holder The portability can be further improved. Moreover, when it is desired to use the pad wall, the pad wall can be immediately brought into a usable state by simply rotating the pad wall.

As mentioned above, the pad wall may be removable from the holder to allow for reduced bulk of the infant carrier when the pad wall is not in use. Further, when the pad wall is rotatably attached to the holding base, an elastic member that urges the pad wall to rotate in a direction in which the pad wall rises from the seat surface, and the pad wall against the elasticity of the elastic member. It may further include a locking member for maintaining the state of extending along the seat surface. With such a configuration, the pad wall can be automatically raised when the engagement by the engagement member is released, so that the operability of the infant holding device can be improved.

The height of the pad wall may be adjustable. In this way, by making the height of the pad wall adjustable, the height of the pad wall can be changed according to the growth of the infant, and due to the existence of the pad wall that is too high compared to the baby's physique, It is possible to prevent the infant holder from becoming unnecessarily bulky. Further, the pad wall may be adjustable in position in the front-rear direction. Since the position of the pad wall in the front-rear direction can be adjusted in this manner, the position of the pad wall can be adjusted according to the growth of the baby.

The pad wall preferably has a T-shaped front shape. This allows the infant to be used in a forward-looking manner, facing the pad wall, i.e., with his back to the wearer, and with his back facing the pad wall, i.e., towards the wearer. It is possible to realize both of the usage state held by the above without any problem. That is, the T-shaped pad wall provides a relatively wide surface for supporting an infant in the upper part thereof, and when the infant sits toward the pad wall, allows the baby's legs to be comfortably arranged. .

Further, it is preferable that both ends of the pad wall are curved in a direction approaching the wearer side when viewed from above. As a result, the pad wall can be adapted to the baby's body, and the baby can be supported more stably. In addition, in the seat surface and the pad wall, at least in a region in contact with the body of the baby, the second cushion member is disposed on the back side of the first cushion member and has a larger elastic coefficient than the first cushion member. It is preferable that the cushion material and the third cushion material, which are arranged on the back side of the second cushion material and have a larger elastic coefficient than that of the second cushion material, are loaded. As described above, according to the cushion structure including the three-layer cushion material, in the normal state, substantially only the first cushion material is deformed, which can give a preferable feeling to the baby, and more With respect to a large impact, the second and third cushion materials sequentially act so as to perform the impact absorbing function, so that high reliability for the impact absorbing function can be expected, and the safety of the infant holder is high. The sex can be further enhanced.

The width of the pad wall may be adjustable. As a result, the width dimension of the pad wall can be changed according to the growth of the infant, and the infant holder is unnecessarily bulky due to the existence of the pad wall whose dimension in the width direction is too large as compared with the size of the infant. Can be prevented. Further, the infant holder according to the present invention may further include a curved surface forming member for forming a curved surface along the buttocks of the baby at an inner corner portion formed between the pad wall and the seat surface. According to such a curved surface forming member, the baby's buttocks can be made more stable while giving a favorable feeling to the baby.

The height of the pad wall 7a can be adjusted.

Since the height of the pad wall 7a can be adjusted in this manner, the height of the pad wall 7a can be changed according to the growth of the baby, and the pad wall is too high compared to the baby's physique. Due to the presence of, the infant holder can be prevented from being unnecessarily bulky. The engagement hole 5 described above
0 and 51 are shaped to form a taper on the outer surface side,
Further, it is preferable that the engagement protrusion 49 is also tapered. This facilitates the operation of disengaging the engagement protrusion 49 from the engagement hole 50 or 51, and allows the engagement protrusion 49 to easily engage with the engagement hole 50 or 51. Become.

Also according to this embodiment, the pad wall 7a
Can be removed from the holding table 6a. Therefore, as in the above-described embodiment, when the pad wall 7a is not used for a relatively long period of time, the pad wall 7a can be removed to further reduce the bulkiness of the infant holder. Next, in FIG. 21, the holding core material 10 and the waist belt 3a are shown in a side view. The waist belt 3a has a front belt portion 30a that passes through the front side of the holding core 10 and a back belt portion 31a that also passes through the back side. The front belt portion 30a and the back belt portion 31a are connected to each other on both sides of the holding core material 10 as in the case of the front belt portion 30 and the back belt portion 31 described above.

In this embodiment, the front belt portion 30a
