The bottom portion 36 is made of a highly cushioned material. The bottom portion 36 has a substantially rectangular shape and is configured to be foldable. The length of the bottom portion 36 in the long side direction is appropriately set based on the average height of the infant so that the infant can lie down. The short side direction of the bottom surface portion 36 corresponds to the shoulder width direction of the infant, and the length of the short side direction of the bottom surface portion 36 is appropriately set so that the infant can lie down. The bottom portion 36 may be configured by, for example, sandwiching a highly cushioned material such as polyurethane, cotton, sponge, or the like between a surface made of a highly breathable mesh material and a lining. As shown in FIG. 6, a crease 37 perpendicular to the gusset width direction is formed at substantially the center of the bottom surface portion 36 in the gusset width direction.

Also, the first side portions 34 and 35 are made of a softer material than the second side portions 32 and 33 and are configured to be foldable. The first side portions 34 and 35 may be made of, for example, lightweight and thin nylon cloth. The first side portions 34 and 35 have a substantially rectangular shape with long sides extending in the gusset width direction. Specifically, the first side portion 34 has a support rod housing portion 34a for housing the support rod 39, and a mesh portion 34b made of a highly breathable and permeable mesh material. Similarly, the first side portion 35 has a support rod housing portion 35a for housing the support rod 39, and a mesh portion 35b made of a highly breathable and permeable mesh material.

The support rod 39 and the lengths in the long side direction of the first side portions 34 and 35 are formed substantially equal. The support rod 39 is constructed, for example, by longitudinally connecting a plurality of relatively short rods. In the folded state, the support rod 39 is disassembled into a plurality of short rods and accommodated inside the bag 1 in the folded state. The lengths of the first side portions 34 and 35 in the long side direction are substantially equal to the length of the bottom portion 36 in the long side direction. An insertion opening (35c in FIG. 5) for inserting the support rod 39 is provided at one end in the long side direction of the support rod housing portions 34a and 35a. A support rod 39 is inserted into the insertion opening. Thereby, the shapes of the first side portions 34 and 35 are maintained, and the first side portions 34 and 35 function as side walls of the second housing portion 40 .

When folding the bag 1, first, the support rods 39 are pulled out from the support rod accommodating portions 34a and 35a. Next, as shown in FIG. 8, the bottom portion 36 is folded along the crease 37 of the central portion and lifted from the bottom, and the second side portions 32 and 33 are brought closer to each other so that the bottom portion 36, the first The sides 34 and 35 are folded.

When the bag 1 is deployed, the procedure is reversed.

In the unfolded state, the bottom portion 36, the first side portions 34 and 35, and the second side portions 32 and 33 form a substantially rectangular parallelepiped second accommodation portion 40 with an open top. An infant is put in from the upper opening of the second storage part 40 and laid down on the bottom part 36 so that the gusset width direction is aligned with the height direction of the infant. Thereby, the infant can be temporarily rested within the second storage section 40 .

Since the first side parts 34 and 35 have a permeable mesh part, the guardian can visually recognize the infant resting in the second storage part 40 from the side direction.

Here, the bag 1 of this embodiment includes a cover portion for covering the upper opening of the second storage portion 40 . FIG. 10 is a diagram showing an example of a cover portion 50 for covering the upper opening of the second accommodation portion 40. As shown in FIG. FIG. 11 is a diagram showing an example of the unfolded bag 1 with the cover portion 50 attached.

The cover portion 50 is made of a softer material than the second side portions 32 and 33, and may be made of, for example, lightweight and thin nylon cloth. The cover part 50 may be made of, for example, a highly breathable and permeable mesh material. As shown in FIG. 10, the cover portion 50 is formed in a substantially rectangular shape when viewed from the front. The length of the cover portion 50 in the long side direction is substantially equal to the length of the first side portions 34 and 35 in the long side direction. Also, the length of the cover portion 50 in the short side direction may be, for example, about 1/2 to 3/4 of the length of the second side portions 32 and 32 in the circumferential direction.

Line fasteners 51 a and 51 b are provided on short sides of the cover portion 50 . A slider 52 is attached to the line fastener 51b. The line fasteners 51a and 51b are used to attach the cover portion 50 to the bag body. When the cover portion 50 is attached to the bag 1, the long side direction of the cover portion 50 coincides with the gusset width direction of the bag 1 in the unfolded state.

Specifically, the starting end of the wire fastener 51a of the cover portion 50 (FIG. 10) and the starting end of the upper fastener 31a of the second side surface portion 32 (FIG. 9) are connected by the slider 30 provided on the upper fastener 31a. The wire fastener 51a of the cover portion 50 and the upper fastener 31a of the second side portion 32 are connected by sliding the slider 30 from the starting end to the terminal end. In addition, the starting end of the line fastener 51b of the cover portion 50 (FIG. 10) and the starting end (not shown) of the upper fastener 31a of the second side surface portion 33 are connected by a slider 52 provided on the cover portion 50, By sliding the slider 52 from the starting end to the terminal end, the wire fastener 51b of the cover portion 50 and the upper fastener 31a of the second side portion 33 are connected. As a result, the cover portion 50 is fixed to the bag body in the unfolded state.

As shown in FIG. 11 , the cover part 50 is attached to the bag body so as to cover the upper opening of the second storage part 40 . The cover part 50 is attached so as to cover the mesh parts 34 b and 35 b of the first side parts 34 and 35 from the upper opening of the second housing part 40 . In this manner, the cover portion 50 can cover the upper opening of the second housing portion 40 .

Here, the cover portion 50 has a length in the short side direction (horizontal direction when attached to the bag main body (shoulder width direction) and length) are defined, but the size of the cover portion 50 is not limited to this. For example, the cover part 50 may be configured to cover the entire upper opening of the second housing part 40 and partially cover the mesh parts 34b and 35b when attached to the bag body. Further, the cover part 50 may be configured so as to cover the entire upper opening of the second storage part 40 and not cover the mesh parts 34b and 35b when attached to the bag body. Moreover, the cover part 50 may be configured to partially cover the upper opening of the second storage part 40 when attached to the bag body.

Also, the line fasteners 51 a and 51 b may be provided on the long sides of the cover portion 50 . In this case, when the cover portion 50 is attached to the bag body, the short side direction of the cover portion 50 coincides with the gusset width direction (height direction) of the bag 1 in the unfolded state.

Moreover, the cover part 50 may be formed in a substantially square shape. In this case, the line fasteners 51a and 51b are provided on the opposing sides, and the sides on which the line fasteners 51a and 51b are not provided are aligned with the gusset width direction of the unfolded bag 1 when attached to the bag body. become.

In this embodiment, the cover part 50 is made of a mesh material with high permeability, but at least a part of the cover part 50 may be made of a material with low permeability. Further, another low-permeability cover covering part or all of the cover 50 may be detachably attached to the cover 50 . For example, the portion of the cover portion 50 corresponding to the upper portion of the second housing portion 40 (the portion corresponding to the upper side of the second housing portion 40 when viewed from the infant) may be made of a material with low permeability. However, another cover with low permeability may be detachably attached to the relevant portion of the cover portion 50 .

As described above, the bag 1 of the present embodiment can cover the upper opening of the second storage section 40 with the cover section 50 . This can protect the infant from, for example, insects, debris and other objects.

In addition, since the cover part 50 is made of a permeable mesh material, the guardian can visually recognize the baby resting in the storage part 40 from the outside. In addition, since the cover portion 50 and the first side portions 34 and 35 are made of a material having high air permeability, the air permeability in the second accommodation portion 40 can be ensured, and heat can be dissipated in the second accommodation portion 40. It is possible to prevent being trapped.

Moreover, since the cover part 50 is configured to be removable from the bag 1 in the unfolded state, the cover part 50 can be attached or removed as necessary.

Further, for example, when simply covering the upper opening of the second housing portion 40 with a cloth, the cloth may be removed by an infant in the second housing portion 40, and the cloth may be removed from the second housing portion 40. However, in this embodiment, since the cover portion 50 is fixed to the bag body, such a problem can be prevented.

Moreover, in this embodiment, the cover part 50 is connected to the line fastener 31 for maintaining the bag 1 in the folded state. Therefore, the cover part 50 can be fixed to the bag body using the line fastener 31 for folding the cover part 50 without providing a separate fixing part for fixing the cover part 50 to the bag body.

Further, in this embodiment, approximately upper halves of the second side surface portions 32 and 33 are connected by the upper fastener 31a, approximately lower halves of the second side surface portions 32 and 33 are connected by the lower fastener 31b, and the bag 1 is folded. be made. In the unfolded state, the line fastener 51 of the cover portion 50 is connected to the upper fastener 31a. As a result, substantially the upper half of the bag 1 in the unfolded state can be covered with the cover portion 50, and the cover portion 50 is fixed to the bag main body in the unfolded state using the upper fastener 31a for folding the bag 1. can do.

Further, in the present embodiment, substantially the lower halves of the second side surface portions 32 and 33 are connected by the lower fastener 31b, so that the cover portion 50 and the support rods can be attached while the lower halves of the second side surface portions 32 and 33 are connected. 39 can be accommodated with the bottom portion 36 and the first side portions 34 and 35 in the folded state. Therefore, for example, the cover portion 50 and the support rods 39 do not need to be accommodated in the first accommodation portion 25, and the first accommodation portion 25 can be effectively utilized.

Further, in the present embodiment, a crease 37 perpendicular to the gusset width direction is formed at substantially the central portion of the bottom surface portion 36 . This makes it easier to fold the bottom portion 36 .

Further, in the present embodiment, the second side surface portions 32 and 33 are formed in a substantially trapezoidal shape with the lower base longer than the upper base, and the first side surface portion 34 extends along the left and right ends of the second side surface portions 32 and 33 . and 35 ends (short sides) are connected. Thus, in the deployed state, the first side sections 34 and 35 have an angle slightly less than 90 degrees with respect to the bottom section 36 . That is, the first side portions 34 and 35 are configured to approach each other as they are separated from the bottom portion. As a result, when folding the bag 1, the first side portions 34 and 35 naturally fall inward when the second side portions 32 and 33 are brought closer while the bottom portion 36 is folded along the central crease 37. , and the bag 1 can be easily folded.
