Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to child-care equipment including a relatively small chair-like bed such as a folding baby carriage, a child's chair, a cradle, a swing, and a chair. The present invention relates to a childcare device that is equipped with a type seat, but can also be used as a simple bed by folding down the backrest, and particularly relates to a chair-like bed of such a childcare device.

[Prior Art] The present applicant filed a patent application dated April 22, 1980,
No. 61 F313 (see Japanese Unexamined Patent Publication No. 57-175320) for ``Childcare appliance with seat'', and proposed a preferred form for the seat of such childcare appliance from the viewpoint of preventing hip dislocation.

In other words, the seat portion of the seat allows for dimensions such that the distance between the groins is maintained at a predetermined value to prevent hip dislocation, and there is no obstacle that presses inward on the outside of both kneecaps of a sitting infant. This is a seat for a childcare appliance with a seat, which is arranged in a space and further includes a pair of positioning members for lateral positioning of the buttocks of an infant placed on the seat. More typically, the seat has a front end longer than its rear end, and has a trapezoidal shape when viewed from above. In addition, as a preferable example, the length of the front edge of the seat is 36 mm based on clinical data.
cm or more.

According to this conventional technology, the infant's buttocks are stabilized.
Since there is no obstacle on the outside of the kneecap that presses it inward, the distance between the infant's groin can be maintained at a predetermined value necessary to prevent hip dislocation, and a stable environment is provided for the infant. You will be able to do this.

[Problems to be Solved by the Invention] FIG. 2 is a diagram showing the natural body shape of an infant lying on a bed, viewed diagonally from above the infant's feet. As shown in this drawing, the legs of an infant in a natural body shape are bent at the hip joints like a frog.

The substantially trapezoidal seat described above is illustrated in FIG. 2 by line 1. 2. It is formed in the area surrounded by 3. Therefore, a space wider than the rear edge of the seat shown by line 3 is formed in the area above the seat where the infant's kneecaps are located. In addition, as mentioned above, on both sides near the boundary between the seat and backrest, which is also indicated by line 3,
A pair of positioning members are provided for lateral positioning of the infant's buttocks. Although not shown in FIG. 2, the positioning member may, for example, form a raised portion at each corner where lines 1 and 2 and line 3 intersect, or may be formed by a pair of side walls rising from the seat. It will be realized.

In conjunction with the seat as described above, the seat is formed with a backrest. For example, in the case of child-care equipment such as a folding baby carriage, where the width dimension cannot be made very large, it is impossible to provide the backrest part so wide, and the seat part is usually provided as shown by line 3. It is formed with a width approximately equal to the length of the rear end edge. That is, in FIG. 2, with the width defined between the two-dot chain line 4.5,
A backrest portion is formed.

The backrest part as mentioned above usually has a seat that rises from both sides of the backrest in order to stably support a seated infant.
A pair of sidewalls is formed. That is, these side walls are located on line 4.5. When the seat takes the form of a chair with the back rest erect, infants often do not sit deeply in the seat, but rather lean forward and move away from the back rest. Experientially.

However, when an infant sleeps and uses the reclining mechanism of such a seat to recline the backrest, the infant's upper body naturally comes into contact with the backrest and is supported by the backrest. Become.

Referring again to FIG. 2, if we take a closer look at the baby's elbows, we will see that they protrude outside the area defined between lines 4 and 5. That is, when an infant is laid down, the pair of side walls rising from both side edges of the backrest portion act as a factor that compresses the infant's natural body shape as shown in FIG. 2.

In this way, in the previous application by the applicant mentioned above, despite efforts to improve the seat area, no consideration was given to the backrest area, and there is still room for further improvement. I understand.

Therefore, the present invention aims to provide a chair-like bed for childcare equipment that does not apply pressure even near the elbows when an infant in a natural body shape as described above sleeps.

[Means for Solving the Problems] The present invention has a seat portion that supports the lower body of an infant and a backrest portion that supports the upper body of the infant. side walls are formed;
A pair of positioning members are provided on both sides of the boundary between the seat and the front rest for positioning the infant's buttocks in the lateral direction, and a pair of positioning members are provided above the seat and on both sides of the boundary between the seat and the frontrest. This is a chair-like bed for child-care equipment in which a space wider than the space between the pair of positioning members is formed in the area where the kneecaps of the child are located, and the above-mentioned problems are solved as follows.

That is, the width between the pair of side walls extending from both side edges of the front rest portion is made wider in the area where the infant's elbows are located than the width between the pair of positioning members.

[Operations and Effects of the Invention] According to the present invention, the pair of side walls formed on the backrest portion are formed, for example, along the lines 6 and 7 shown in FIG.
It is made wider in the area where the infant's elbow is located. This prevents the side edges of the backrest portion from compressing the natural body shape of a lying baby at the elbows. Therefore, a chair-like bed for child-care equipment, which is normally desired to be small, can provide excellent comfort without increasing its size significantly.

The pair of positioning members that position the infant's buttocks in the lateral direction also function to position the infant's upper body with respect to the backrest portion. That is, 1 like this
The pair of positioning members also allows the infant's upper body to be positively positioned approximately at the widthwise center of the backrest portion. This means that the limited width of the backrest
By using it effectively, it helps to ensure that there is room on both sides of the infant's torso. If such a positioning member does not exist, the infant's upper body may be positioned to one side of the backrest, and in this case, even if the area where the infant's elbows are located, the backrest Even if the width between the side walls of the elbow is wide, one of the elbows will be compressed by the side wall on the side on which the elbow is located. For this reason, the dimensional features provided to both side walls of the backrest according to the present invention are closely related to the positioning member for the buttocks.
It can be said that this effect is being demonstrated.

[Example 1] FIG. 1 is a perspective view showing only a chair-like bed provided in the childcare equipment according to the present invention.

The chair-like bed 10 shown in FIG. 1 schematically shows an embodiment of the present invention, and includes a seat portion 11 that supports the lower body of an infant, and a backrest portion 12 that supports the upper body of the infant.
It has A pair of rising side walls 13° and 14 are formed on both side edges of the backrest portion 12. Further, it is preferable that an upper end wall 15 is also formed along the upper end edge of the backrest portion 12 so as to connect each end of the pair of side walls 13. Furthermore, preferably, a pair of side walls 16, 17 are formed rising from each portion of both side edges of the seat portion 11.

The chair-like bed 10 may be configured so that the inclination angle of the backrest portion 12 can be changed. In this case, the side walls 13 and 16 and the side walls 14 and 17 are separated or configured to be deformable. In addition, the first
In the figure, the backrest portion 12 of the chair-like bed 10 is not completely horizontal, but is slightly inclined.

A pair of positioning members 19 and 20 are provided on both sides near the boundary 18 between the seat portion 11 and the backrest portion 12 for lateral positioning of the infant's buttocks. In this embodiment, no special member is provided as the positioning members 19.20, and the aforementioned ends of the side walls 13.14 and 16.17 constitute the positioning members 19.20.

Focusing on the seat portion 11, a pair of positioning members 19.
A space wider than 20 ken is formed. That is,
In this embodiment, the seat 11 has a substantially trapezoidal shape.

The pair of side walls 13,14 of the backrest portion 12 are formed such that the width therebetween gradually increases from the lower end to the upper end of the backrest portion 12. As a result, the width between the pair of side walls 13.14 is wider than the width between the pair of positioning members 19.20 in the area where the baby's elbows are located.

As mentioned above, by choosing the width between the pair of side walls 13.14, the space above the backrest part 12 is provided as defined between the lines 6.7 in FIG.
You can take on a natural body shape as shown in Figure 2 without putting pressure on your elbows.

Note that the shape in which both side edges of the backrest portion 12 extend, that is, 1
The form of the pair of side walls 13,14 is not limited to that shown in FIG. For example, the width between the pair of side walls may gradually and uniformly widen from the lower end of the backrest toward the upper end, and the planar shape of the backrest may be an inverted trapezoid. Further, the backrest portion may have an inverted "convex" shape in plan view, and a pair of side walls may be formed rising from both side edges of the backrest portion. In any case, it is sufficient that the width between the pair of side walls is wider than the width between the pair of positioning members in the area where the baby's elbows are located.

In addition, when a pair of side walls 13 and 14 are formed as shown in FIG. 1, a wider width is ensured also in a region closer to the lower body than the region where the baby's elbows are located. In such a case, the pair of side walls 13 and 14 will not get in the way of an adult's hands when placing an infant brought from outside the chair-like bed 10 onto such a chair-like bed 10. , which has the advantage of making it easier to put infants to sleep.
