From the above, as shown in FIG.
While the 16 and the support body 11 are stored, the baby can be held by holding the belt 13 on one of the shoulders of the wearer while facing the wearer of the holding tool 1.

As described above, according to the holder 1 according to the embodiment of the present invention, (1) the one-shoulder type is shown in FIG.
As shown in (a), the infant is held and used in a state of facing the wearer, or (2) the two-shoulder type is used so that the infant is opposed to the wearer as shown in FIG. 6 (a). You can use it by holding it in a state, or (3) by using it as a two-shoulder type so that the back of the baby touches the abdomen of the wearer of the holding tool 1.
(4) With the belts 15 and 16 and the support body 11 stored,
As shown in FIG. 8, an infant can be held and used while facing the wearer, and the infant can be held in four ways.

The hug 1 according to the embodiment of the present invention.
According to the description, the male buckles 13a and 15a and the female buckle 14 are
By selecting one of the combinations of fitting with a and 16a, it is possible to easily switch the usage form between the one-shoulder type and the two-shoulder type.

When the hug 1 is used as a one-shoulder type, a child's buttocks tend to be biased to the left or right, but as shown in FIG. 9, the tag 11b is inserted in the leg hole 11a to perform three-dimensional sewing. By forming the support main body 11 in this way, it is possible to suppress the lateral displacement of the buttocks of the child.

Next, a hug tool 2 according to a modification of the embodiment of the present invention will be described with reference to FIGS. 10 and 11. The same reference numerals as those used in the above description indicate the same members. The hug tool 2 according to the modified example of the embodiment is the same as the hug tool 1 described above in that it can hold an infant in four ways, but each of the bands 13 to 16 is different from each other. The difference is that the members to be connected are different.

As shown in FIG. 10, the hug 2 includes a belt 1
Female buckles 13b and 15b are attached to the tips of 3, 15 and extension bands 13 are attached to these female buckles 13b and 15b.
c, 15c are extended, and these extension bands 13c,
It is characterized in that the male buckles 13d and 15d are attached to the tip of 15c and the D-cans 14b and 16b are attached to the tips of the belts 14 and 16, respectively.

Female buckle 13b and female buckle 15b
Are formed in the same shape, and the male buckle 13d and the male buckle 15d are formed in the same shape. The female buckles 13b and 15b and the male buckles 13d and 15d are fitted with each other. Here, as an actual attachment method, as shown in FIG. 11A, the male buckles 13d and 15d are inserted into the openings of the D-cans 14b and 16b, and then the male buckles are shown as shown in FIG. 11B. By coupling 13d, 15d and the female buckles 13b, 15b, the connection of the respective bands 13-16 is completed.

According to the holding device 2 thus constructed, the male buckles 13d and 15d are replaced by the female buckles 13b and 1b.
When it is disengaged from 5b, as shown in FIG. 11 (c), the male buckles 13d and 15d are caught by the D cans 14b and 16b. Therefore, the male buckles 13d, 15
Even if d suddenly comes off the female buckles 13b and 15b, the male buckles 13d and 15d are attached to the D cans 14b and 16b.
Since the belt is locked, it is possible to secure a state in which the shoulder belt is always hung on one shoulder even when the belt 13 and the belt 14 are connected and used as a shoulder belt. Therefore, it is safe even if the buckle suddenly comes off,
Infants can always be held in a stable state.

Next, a hug tool 3 according to an application example of the embodiment of the present invention will be described with reference to FIGS. The same reference numerals as those used in the above description indicate the same members. A hug tool 3 according to an application example of the embodiment
There is no difference in that an infant can be held by four methods as in the case of the hugs 1 and 2 described above, but it is provided with a safety valve as compared with the hug 3 described above. Differences in points.

FIG. 12 is a perspective view showing a structural example for connecting the extension bands 13c, 15c and the bands 14, 16 of the holder 3 according to the application example of the embodiment of the present invention. As shown in FIG. The holding tool 3 is configured to include the attachment / detachment suppressing member 20. As shown in FIG. 13, the attachment / detachment restraining member 20 is pivotally mounted in an annular member 21 having an opening 21a through which the extension bands 13c and 15c are inserted, and rotatably in the opening 21a of the annular member 21. And a safety valve 22.

As shown in FIG. 14 (a), the annular member 21 is constructed with a hole 21b into which the shaft 22a of the safety valve 22 is pivotally mounted. The safety valve 22 is, as shown in FIG. 14 (b), It is formed by including an inclined protruding piece 22b and a slit 22c through which the bands 14 and 16 are inserted. Further, as shown in FIG. 12, a strip 30 for adjusting the length is attached to the strips 14 and 16 so that the strips 14 and 16 are engaged so that the adjusted lengths of the strips 14 and 16 are kept constant. It is supposed to stop.

According to the hug tool 3 having the attachment / detachment restraining member 20 configured as described above, the extension bands 13c and 15c and the bands 14 and 16 are connected to each other as shown in FIGS. 12 and 15. Even if the male buckles 13d and 15d (see FIG. 10) attached to the ends of the extension bands 13c and 15c come off from the female buckles 13b and 15b from such a state,
The male buckles 13d and 15d have an annular member 21 and a safety valve 22.
With the projecting piece 22b, the opening 21a is locked so as not to be inserted. Therefore, the male buckles 13d, 15d
Is suddenly released from the female buckles 13b and 15b,
Although the male buckles 13d and 15d move to the position of the annular member 21, the male buckles 13d and 15d are locked to the attachment / detachment restraining member 20 to connect the belt 13 and the belt 14 and use them as a shoulder belt. Even while wearing, you can ensure that this shoulder belt is always hung on one shoulder. Therefore, it is safe even if the buckle comes off, and the baby can always be held in a stable state.

Note that, for example, as shown in FIG. 15, when the annular member 21 is pulled in the X direction by the extension bands 13c and 15c and the safety valve 22 is pulled in the X direction by the bands 14 and 16, the safety valve 22 The distance L between the tip of the protruding piece 22b and the annular member 21 (see FIG. 15) is determined by the extension bands 13c, 1
It is preferable that the distance is set such that 5c can slide.

In addition, in the description of the above-described hug tool 3, the case where the attachment / detachment restraining member 20 is configured to include the annular member 21 has been described, but instead of the annular member 21, a substantially U-shape shown in FIG. It may be configured by using a U-shaped member 23 such as a shape.

Further, in the above description, the case where the fastening member is composed of the fasteners 18a and 18b is exemplified, but in addition, it may be composed of a surface fastener or the like. The present invention can be implemented in various forms other than the above-described details without departing from the spirit of the invention.

[0043]

According to the hug of the present invention, when holding an infant, the mode for holding the infant can be switched by a simple operation. Further, since the shoulder belt can be hung on both shoulders, it is possible to reduce the burden on the shoulder of the wearer when using the hug.
