Description

[Detailed description of the invention] [Industrial application field] This invention relates to childcare equipment equipped with a seat for infants, such as a childcare chair or a baby carriage.
In particular, the present invention relates to improvements for providing infants with an environment that actively maintains their natural biological structure and does not hinder their free growth.

[Conventional technology] Our country, along with the Indians of North America and Canada, the Laps of Northern Europe, Italy, and West Germany,
It is one of the countries with the highest incidence of congenital hip dislocation, and this disease consistently ranks first among all congenital diseases in infants and children. The incidence of this condition is estimated to be approximately 1 in 20 people, including complete dislocation as well as milder cases such as subluxation and acetabular dysplasia.

In all of the countries mentioned above where congenital hip dislocations occur, there is a custom of wrapping infants with their legs stretched out, and in Japan there was a time when infants were wrapped in rolled diapers or triangular diapers to tighten their legs and keep their hips stretched out. Ta.

Based on these findings, it has been found that the majority of congenital hip dislocations occur when infants are restrained with their legs extended, preventing their legs from freely moving in the very early neonatal period. Immediately after birth, infants should wear crotch diapers and loose-fitting clothing that do not hinder the movement of their legs and allow them to freely spread their legs in a very natural way, i.e., bend their hips in a frog-like position. As a result, the incidence of congenital hip dislocation has decreased dramatically.

The factors that prevented the natural healing of congenital hip dislocation and worsened the disease were not limited to diapers and clothing. The backpack straps used to carry infants on their backs have gradually become obsolete due to changes in lifestyle, and side straps are now more commonly used. In the case of a side-hugging band, the legs are stretched out with the buttocks in the center, and the entire body is restrained in a long and narrow manner, forcing the person to remain in that unnatural posture for a long time.

In addition, baby carriages began to become popular after the war, but most of the ones currently in use do not carry infants lying down, but instead have a chair-shaped hammock attached to them. What's more, these baby carriages have become smaller, and the seat of the hammock has changed into a bag-like shape, just as the shoulder strap has changed into a side-carrying band.

Thus, it is thought that the childcare environment may have placed abnormal pressure on the infant's hip joint, leading to hip dislocation.

The dislocation of the hip joint was discovered during a regular health checkup at a public health center, and the patient is receiving guidance. In this case, the infant is handled so that the legs are bent and can be spread freely.

If an infant has a dislocated hip, he or she will have difficulty walking. However, even if the symptoms of dislocation are slight, or even if the dislocation hardens without adequate treatment, it is relatively often left untreated as it does not have a direct impact on life. If the child continues to grow, the hip joint will become painful and stiff, and the movement of the legs will gradually become worse, leading to the development of osteoarthritis of the hip, which is fundamentally incurable.

[Problems to be solved by the invention] Based on the above-mentioned concept, it is desired to develop childcare equipment that matches the posture of infants to their most natural living body and does not interfere with their free movement functions.

Therefore, the purpose of this invention is to provide a child care appliance with a seat that can satisfy the above-mentioned demands.

[Means for Solving the Problems] This invention is a child care appliance with a seat, which is equipped with a seat for an infant and a crotch belt extending upward from the front end of the seat. Therefore, the above-mentioned technical problem is solved as follows.

In other words, it is located in the crotch of a sitting infant.
A corrective attachment is removably attached to the crotch belt and defines the distance between the crotches to a predetermined value or more in order to prevent hip dislocation, and the corrective attachment has a space that allows the infant to move on his or her own. It has elasticity so that it remains.

[Function] When the above-mentioned corrective attachment is attached to the crotch belt, it is located between the crotches of the infant and regulates the distance between the crotches to be greater than a predetermined value to prevent dislocation of the hip joint. Furthermore, since the correction attachment has elasticity, it does not prevent the infant from moving on his or her own.

[Example] FIGS. 1 and 2 are perspective views showing examples of a childcare chair and a baby carriage, respectively, to which this invention is directed.

The childcare chair shown in FIG. 1 can be used from a few days after birth. A seat 1 is provided there. The seat 1 includes a seat portion 2 and a backrest portion 3. The backrest portion 3 is configured to be reclinable, and can be used as a chair or a bed. Wheels 4 are provided below, by which the childcare chair can be easily moved to a suitable location. This wheel 4 is configured to be able to change its position upward, so that the curved lower frame 5 comes into contact with the floor surface, and it can also be used as a cradle.

The baby carriage shown in FIG. 2 can be used from two months after birth. A seat 1 is provided there, similar to the childcare chair shown in FIG. The seat 1 includes a seat part that is hidden and cannot be shown in the drawings, and a backrest part 3. This backrest portion 3 is also configured to be reclinable, and can be shaped into a chair shape or a bed shape. Wheels 4 are provided below.

On the other hand, FIG. 17 is an illustrative diagram showing the basic natural body shape of an infant. As shown here, in a natural body shape, the legs are bent at the hip joints and spread apart like a frog. In this way, the conditions for providing a natural living body, that is, an environment that actively maintains the healthiest and most comfortable posture and does not hinder free growth, are such that the width W of the kneecap part when the crotch is widened is greater than a predetermined value. When the natural state is maintained and the infant moves on his own,
The goal is to ensure that there is no resistance. This natural organism must be actively preserved, especially up to 6 months of age.
This period is the most important period. It is known that the average maximum width W during this period was 350 mm.

The childcare chair and the baby carriage seats 1 shown in FIGS. 1 and 2, respectively, directly influence the posture of an infant. Therefore, it will be understood that it is necessary to provide such a seat 1 with an environment that positively preserves the natural living body and does not hinder free growth. In the following, embodiments of the invention will be described with particular reference to the seat 1, with reference to the drawings.

FIGS. 3 and 4 are diagrams for explaining one embodiment of this invention. In order to realize this embodiment, a correction attachment 1 as shown in FIG.
1 is prepared. The correction attachment 11 is made of a flexible material such as a sponge. Further, the correction attachment 11 may be constructed by wrapping a sponge-like material with a suitable sheet material. In conjunction with the seat 1 shown in FIG. 4, a crotch belt 12 is provided that extends upward from the front end of the seat portion 2. The configuration of the seat 1 including the crotch belt 12 has been conventionally applied to child care chairs and baby carriages. That is, this embodiment is intended to add a separately prepared correction attachment 11 to an existing instrument. The corrective attachment 11 can be bent as shown in phantom lines in FIG. 3, and in this state is attached extending from the crotch belt 12 to the front end of the seat portion 2, as shown in FIG. Corrective attachment 11 at this time
Various types of fixing means can be used. For example, by using a hook, button, velvet fastener, string, or the like as a fixing means, the corrective attachment 11 can be attached as needed and removed when no longer needed.
Therefore, there is an advantage that the corrective attachment 11 can be attached to an existing device until the child is six months old, and removed after that age.

FIG. 5 is a perspective view showing another example of the correction attachment. 6 is an end view of the cut portion taken along the line - in FIG. 5, FIG. 7 is an end view of the cut portion taken along the same line -, and FIG. 8 is an end view of the cut portion taken along the line - of FIG.
It is a cut part end view along.

The corrective attachment 11 shown here is preformed so that its three-dimensional shape extends from the crotch belt 12 to the front end of the seat portion 2 shown in FIG. The material may be a sponge-like material or a material covered with a sheet material, as in the example shown in FIG. The three-dimensional shape of such correction attachment 11 is shown in FIGS. 6 to 8.
This can be understood from the cut end view shown in the figure. The correction attachment 11 can be fixed in the same way as in the example shown in FIG.

Incidentally, in order to achieve the original purpose of the correction attachment 11 described in the two examples above, its dimensions, especially the width, must be appropriately selected. Width W shown in Figure 17 is 350mm
Therefore, the maximum width of the correction attachment 11 is preferably 100 to 150 mm.

Figures 9 to 11 are for explaining an example of how to attach the orthodontic attachment shown in Figure 5. Figure 9 shows the attachment before installation, Figure 10 shows it after installation, and Figure 11 shows the attachment. 10 shows the arrangement order of each belt in the state shown in FIG.

Crotch belt 12 (fourth
An upper attachment belt 21 that extends upward, a right attachment belt 22 that extends to the right in the figure, and a left attachment belt 23 that extends to the left in the figure are attached to the edge of the surface in contact with the figure. At the end of the upper mounting belt 21, a male hook 24 is provided on the front side according to FIG. At the end of the right mounting belt 22,
A female hook 25 is provided on the opposite side according to FIG. Although the female hook 25 is illustrated in FIG. 9, it should be understood that the clasp for attaching the female hook 25 is actually illustrated.
A through hole 26 is provided at the end of the left attachment belt 23.

Such a correction attachment 11 is attached and held there by using a crotch belt 12 extending in the vertical direction and a torso belt 14 extending in the horizontal direction. Referring to FIGS. 10 and 11, the correction attachment 11 is placed in the position shown in FIG. The right attachment belt 22 is then folded at its base and placed over the crotch belt 12 . Next, the left attachment belt 23 is bent at its base and overlapped on the right attachment belt 22. At this time, the female hook 25 is exposed from the through hole 26. Finally, the upper attachment belt 21 is folded over the crotch belt 12 and the torso belt 14 and overlapped on the left attachment belt 23. Here, male hook 2
4 is inserted into the female hook 25 through the through hole 26. This completes the installation of the adjustment attachment 11 and its positioning. When removing the correction attachment 11, the upper mounting belt 21 may be separated from the right mounting belt 22. In response, the male hook 24 is pulled out from the female hook 25, the belts 21, 22, 23 are separated from each other, and the corrective attachment 11 can be removed from the crotch belt 12 and torso belt 14.

FIG. 12 is a diagram showing another example of the method of attaching the correction attachment shown in FIG. 5.

The corrective attachment 11 shown here is provided with only a right attachment belt 22 and a left attachment belt 23. Although detailed illustrations are omitted, the right attachment belt 22 is provided with a female hook, and the left attachment belt 23 is provided with a male hook 24.

The attachment method is to first stack the right attachment belt 22 on the crotch belt 12, then lay the left attachment belt 23 on top of it, and then fit the male hook 24 into the female hook. According to this, crotch belt 1
A right attachment belt 22 and a left attachment belt 23 are coupled so as to surround 2. In this way, the orthodontic attachment 11 can also be mounted and positioned.

FIGS. 13 to 15 are views sequentially showing still other examples of correction attachments and their attachment methods.

Referring to FIG. 13, the orthodontic attachment 27 shown here includes a substantially rectangular body portion 27.
8 and an upper mounting belt 29 extending upwardly therefrom. The main body portion 28 has a structure in which two sheet materials are stacked, and specific portions a, b, c, d,
Spaces e and f are filled with an elastic, for example, sponge-like material. Each location filled with sponge-like material is separated by a seam or seal 30. The amount of spongy material at each location a, b, c, d, e, f is set appropriately, and is taken into consideration so as to provide the most appropriate effect on infants in the manner of use described below. A right mounting lug 31 is formed in the upper right portion of the main body portion 28 in the figure, and a left mounting lug 32 is formed in the upper left portion. Each mounting ear 31, 32 is not filled with sponge-like material. A through hole 33 is provided in the right mounting ear 31. A female hook 34 is provided on the left mounting ear 32. The female hook 34 is actually provided on the back side as shown in the figure. Furthermore, the upper mounting belt 29 has
A male hook 35 is provided to form a pair with this female hook 34. The male hook 35 is provided on the front surface as shown in the figure.

Such a correction attachment 27 is also attached to the crotch belt 12 and torso belt 14 while being held therein. Also, during the installation step, the main body portion 28 is shaped into a desired shape. The method of attaching the correction attachment 27 will be described below with reference to FIGS. 14 and 15.

Referring to FIG. 14, the correction attachment 27
are arranged along the rear of the crotch belt 12 as shown. In this state, first, the left attachment ear 32 is pulled so as to overlap the crotch belt 12. At this time, bending will occur mainly at the location a filled with the sponge-like material. Next, the right mounting ear 31 is pulled onto the left mounting ear 32.
Correspondingly, folding will occur primarily at the location c filled with sponge-like material.
In this way, the female hook 34 on the left mounting ear 32
is exposed from the through hole 33 on the right mounting ear 31.

Next, as shown in FIG.
9 is folded over the crotch belt 12 and torso belt 14 and its end is brought over the right attachment ear 31. In this state, male hook 3
5 is fitted into the female hook 34 through the through hole 33. In this way, the orthodontic attachment 27
has been installed and positioned in relation to the crotch belt 12 and torso belt 14. Moreover, in addition to this, the main body portion 28 of the correction attachment 27 is appropriately deformed and shaped so that the correction attachment 27 can perform its original function in such an attached state.

Figure 16 shows the orthodontic attachment 2 in Figure 13.
7 is shown. According to the installation method shown here, the parts a, b, filled with sponge-like material,
It is folded through a seam or seal 30 that separates c and the same locations d, e, and f. With this bending, the parts d, e, f filled with sponge-like material
includes both mounting ears 31, 32 and the crotch belt 12,
It will be in a state where it is caught between points a, b, and c.

According to the attachment method shown in FIG. 16, the "bulge" in the main body portion 28 of the correction attachment 27 can be further increased. In other words, the correction attachment 11 shown in FIG. 5, which is generally relatively difficult to manufacture, has a three-dimensional shape.
It can be said that it can be easily obtained not by its manufacturing operation, but rather by its installation operation.

In addition, when applying the attachment method of FIG. 16, it may be necessary to make the upper attachment belt 29 longer than in the case of FIG. 15.

Thus, in each of the embodiments described with reference to FIGS. 9 to 16, the mounting positions of the male hook 24 or 35 and the female hook 25 or 34 may be reversed. Further, instead of the detachable attachment method using hooks, buttons, velvet fasteners, strings, etc. may be used.

Above, Figures 3 and 4, Figures 5 to 8,
Figures 9 to 11, 12, and 13
In each of the embodiments shown with reference to FIGS.
is constructed using a sponge-like flexible material. In this case, the degree of resistance of the corrective attachments 11, 27 or the crotch belt 13 in the direction of contraction or expansion in the width direction can be arbitrarily changed by selecting the material. The degree of resistance in the direction of contraction or expansion can also be adjusted by embedding a spring in place of or in combination with selecting a flexible material. In addition, orthodontic attachment 1
1 and 27 and the crotch belt 13, an example of the cross-sectional shape is illustrated, but the cross-sectional shape is not particularly limited to this. In short, the selection of materials and cross-sectional shapes must be selected in such a way that infants can maintain a natural position with their legs spread, and there is no resistance when infants move on their own. That means it's fine.

Although not directly related to the gist of this idea,
Needless to say, in order to expect the effects of this invention, the width must be greater than the width W shown in Fig. 17, for example 350 mm.
The seat portion 2 must be configured with the above width.

Furthermore, this invention is applicable not only to childcare chairs and baby carriages, but also to any childcare equipment that has a seat for an infant to sit on.

[Effects of the invention] As described above, according to this invention, a corrective attachment is provided to regulate the distance between the infant's groins to a predetermined value or more in order to prevent hip dislocation. Can be actively held. In addition, the correction attachment has elasticity and is configured to allow room for infants to move on their own.
It is also possible to provide an environment that does not hinder free growth. The corrective attachment is also attached to the crotch belt using the crotch belt. Therefore, since the crotch belt is originally located in the crotch of an infant, it is possible to provide an appropriate position to the corrective attachment attached thereto. Furthermore, since the correction attachment is detachably attached to the crotch belt, it can be easily removed when it is no longer needed. That is, such corrective attachments are important until the baby is six months old, after which they may become a hindrance. In this case, it is extremely advantageous if the corrective attachment is removable. In addition, since a crotch belt is usually provided at the front of childcare equipment that has a seat for infants to sit on, it is possible to prevent hip dislocations by simply providing a corrective attachment for conventional childcare equipment. The important effect of prevention can be expected.
