Abstract
Description
[Technical Field]
[0001] The present invention relates to a belt-like baby carrier that is worn diagonally across one shoulder of the user. [Background technology]
[0002] Belt-shaped baby carriers that are worn diagonally across one shoulder of a user are known. For example, the shoulder belt (baby carrier) described in Patent Document 1 includes a back support (seat) that supports the buttocks and other parts of an infant and allows the infant to sit, and a connecting belt (shoulder portion) that is worn over one shoulder of the user. The connecting belt has a shoulder strap portion that fits over the upper part of the user's shoulder and an upper arm strap portion that fits around the outside of the user's upper arm. With the shoulder belt described in Patent Document 1, the two belts, the shoulder strap portion and the upper arm strap portion, can distribute the load on the user's shoulder, allowing the user to wear the shoulder belt comfortably. In recent years, such belt-like baby carriers have become lighter, so users fold them up small and carry them around in their bags. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-058726 Summary of the Invention [Problem to be solved by the invention]
[0004] However, when using a belt-like baby carrier, it is unfolded and draped over the user's shoulders while holding the baby. Therefore, if the carrier is made of a lightweight, soft material such as nylon, as in eco-bags, and the material is folded up small, the shape of the carrier will not return to its original shape when in use, and it cannot be easily unfolded.
[0005] An object of the present invention is to provide a belt-like baby carrier that can be easily unfolded when in use even when the fabric is folded small. [Means for solving the problem]
[0006] The baby carrier of the present invention is a belt-like baby carrier that is worn diagonally across one shoulder of the user, and comprises a seat portion on which the infant sits, a shoulder strap portion that is worn over one shoulder of the user, and a connecting portion that connects the seat portion and the shoulder strap portion, wherein at least one of the members of the seat portion and the shoulder strap portion is formed in a band shape having a longitudinal direction and a lateral direction, and one of the members has an auxiliary member attached so as to extend from one end to the other end in the lateral direction, and the auxiliary member is made of a fabric that is harder than the fabric of the one of the members.
[0007] With this configuration, the auxiliary member is attached to at least one of the seat and shoulder portions so as to extend from one end to the other in the short direction, and because it is made of a harder material than the material of the other portion, it is less likely to retain its shape when folded compared to the other portion, and the shape of the auxiliary member is more likely to return to its original state naturally. Therefore, according to the present invention, the baby carrier can be easily unfolded when in use, even if the material is folded up small.
[0008] In the present invention, the auxiliary member is preferably attached so as to extend along the short side direction of one of the members.
[0009] With this configuration, the auxiliary member is attached so as to extend along the short side of one of the members, so that the other member can easily spread out in the short side, and the baby carrier can be quickly and easily spread out when in use even if the fabric is folded up small.
[0010] In the present invention, it is preferable that one of the members is formed by overlapping two pieces of fabric, and the auxiliary member is attached between the two pieces of fabric.
[0011] With this configuration, the auxiliary member is attached between two pieces of fabric, so that the auxiliary member can be hidden within the fabric of one of the members, improving the design of the baby carrier. [Brief explanation of the drawings]

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which a baby carrier according to one embodiment of the present invention is used. As shown in FIG. 1, the baby carrier 1 is a belt-like baby carrier that is worn diagonally across one shoulder of an adult A who is the user. The baby carrier 1 comprises a seat part 2 for seating an infant C, a shoulder part 3 for hanging on one shoulder of an adult A, and a connecting part 4 for connecting the seat part 2 and the shoulder part 3.
[0014] Fig. 2 is a perspective view showing the entire baby carrier, and Fig. 3 is a view showing the baby carrier placed on a flat surface. 2 and 3, the seat 2 has two straight short sides and two arc-shaped long sides, and is formed in a band shape having a longitudinal and lateral direction as a whole. The seat 2 is formed by overlapping two pieces of nylon fabric, and has an auxiliary member 21 attached to the end on the shoulder strap 3 side and an auxiliary member 22 attached to the center. The auxiliary members 21 and 22 are tape-like members made of polypropylene and are attached between the fabric of the seat portion 2. Specifically, the auxiliary members 21 and 22 are attached so as to extend along the short side of the seat portion 2 (the left-right direction on the paper in FIG. 3) from one end to the other. Here, the auxiliary members 21 and 22 are made of a fabric that is harder than the fabric of the seat portion 2.
[0015] The shoulder strap 3 has two straight short sides and two straight long sides, and is formed in a band shape having a longitudinal and lateral direction as a whole, one end of which is sewn and fixed to one end of the seat 2. The shoulder strap 3 is formed by overlapping two pieces of nylon fabric, and has an auxiliary member 31 attached to the end on the connection part 4 side and an auxiliary member 32 attached to the center. The auxiliary members 31, 32 are tape-like members made of polypropylene and are attached between the pieces of fabric of the shoulder strap 3. Specifically, the auxiliary members 31, 32 are attached so as to extend along the short side of the shoulder strap 3 (the left-right direction on the paper in FIG. 3) from one end to the other. The auxiliary members 31, 32 are made of a fabric that is harder than the fabric of the shoulder strap 3.
[0016] Additionally, the shoulder strap 3 is equipped with two pieces of fluorescent fabric 33, 34 attached at the positions where the auxiliary members 31, 32 are attached. Each piece of fluorescent fabric 33, 34 is attached to the flat surface of the shoulder strap 3, which is the outer surface when the bag is worn diagonally across one shoulder of adult A. Therefore, the shoulder strap 3 glows even in the dark, increasing the safety of the adult A who is using it and making it easier to find when carrying it in a bag or the like. Furthermore, the shoulder strap part 3 is provided with a label 35 attached closer to the connecting part 4 than the fluorescent fabric 33. This label 35 displays the product name of the baby carrier 1.
[0017] The connecting part 4 includes a polypropylene belt 41 and a ladder lock 42 that is fixed to the other end of the shoulder strap part 3 and through which the belt 41 is passed to adjust and fix the length of the belt 41. One end of the belt 41 is sewn and fixed to the other end of the seat part 2. Therefore, the connection part 4 connects the seat part 2 and the shoulder part 3 with the belt 41 and the ladder lock 42. The belt 41 also has a rubber band 412 attached to the other end thereof. The rubber band 412 is used to adjust the length of the belt 41 and to tie up any excess length.
[0018] 3, at one end of the belt 41, an end 411 having a predetermined length is inserted between the fabric of the seat portion 2. This end 411 functions as an auxiliary member in the same way as the auxiliary members 21 and 22, and can be said to be attached so as to extend along the short side of the seat portion 2 (the left-right direction on the paper in FIG. 3) from one end to the other. Here, like the auxiliary members 21 and 22, the end 411 is made of fabric that is harder than the fabric of the seat portion 2.
[0019] FIG. 4 is a diagram showing a pocket provided in the seat portion. As shown in Figure 4, the seat 2 has a pocket 23 provided on the outer surface of the seat 2 (the surface opposite to the surface on which the baby C sits) when used by hanging the carrier diagonally across one shoulder of the adult A. This pocket 23 is provided by sewing a roughly rectangular piece of nylon fabric onto the surface of the seat 2.
[0020] FIG. 5 is a diagram showing the state in which the opening of the pocket is open. 5, pocket 23 has a bottom 231 located on the shoulder strap 3 side and an opening 232 located on the center side of seat 2. Pocket 23 also has fluorescent fabric 233 attached to the back side of the fabric of pocket 23 along the edge of opening 232, and a loop-shaped hook 234 attached to the inner surface of opening 232.
[0021] FIG. 6 shows the pocket inside out. The pocket 23 is used with its fabric turned inside out, as shown in Figure 6. By turning the fabric of the pocket 23 inside out, the fluorescent fabric 233 and hooks 234 described above are exposed to the outside.
[0022] FIG. 7 shows the state in which the shoulder strap and the connecting part are stored inside the pocket. As shown in Figure 7, pocket 23 can accommodate folded parts of baby carrier 1, such as shoulder strap 3 and connecting part 4. Therefore, the user (adult A) can fold baby carrier 1 into a small size and carry it around in a bag.
[0023] According to this embodiment, the following actions and effects can be achieved. (1) Auxiliary members 21, 22, 31, 32 and end 411 are attached so as to extend from one end to the other in the short direction of at least one of seat portion 2 and shoulder portion 3, and are made of a fabric that is harder than the fabric of one of the members, so they are less likely to retain their shape when folded compared to the other of the members, and the shapes of auxiliary members 21, 22, 31, 32 and end 411 tend to return to their original shape naturally. Therefore, baby carrier 1 can be easily unfolded when in use, even if the fabric is folded up small.
[0024] (2) Auxiliary members 21, 22, 31, 32 and end 411 are attached so as to extend along the short side of one of the members, so that one of the members can easily expand in the short side, and baby carrier 1 can be quickly and easily expanded when in use even if the fabric is folded small. (3) Since the auxiliary members 21, 22, 31, 32 and the end 411 are attached between two pieces of fabric, the auxiliary members 21, 22, 31, 32 and the end 411 can be hidden in the fabric of one of the members, thereby improving the design of the baby carrier 1.
[0025] [Modifications of the embodiment] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. For example, in the above embodiment, the auxiliary members 21, 22, 31, 32 and the end portion 411 were attached so as to extend from one end to the other in the short direction of both the seat portion 2 and the shoulder rest portion 3, but it is sufficient if they are attached to at least one of the members.
[0026] In the above embodiment, the connection part 4 connects the seat part 2 and the shoulder part 3 with the belt 41 and the ladder lock 42, but the seat part and the shoulder part may be connected with other members such as a buckle, or the seat part and the shoulder part may be connected directly. In short, the connection part may be any part that connects the seat part and the shoulder part. In the above embodiment, the fabric of the auxiliary members 21, 22, 31, 32 and the end portion 411 is made of polypropylene, and the fabric of the seat portion 2 and shoulder portion 3 is made of nylon. However, the fabric of the auxiliary members, the seat portion, and the shoulder portion may be made of any material, as long as the fabric of the auxiliary members is harder than the fabric of the other member.
[0027] In the above embodiment, the auxiliary members 21, 22, 31, 32 and the end portion 411 are attached so as to extend along the short side direction of the seat portion 2 and the shoulder rest portion 3. However, the auxiliary members do not have to extend along the short side direction, and may extend, for example, obliquely relative to the short side direction. In the above embodiment, the auxiliary members 21, 22, 31, 32 and the end portion 411 are attached between the two pieces of fabric, but the auxiliary members may be attached to the outside of the fabric.
