Description

Technical Field

[0001] This utility model belongs to the technical field of baby carriers, specifically relating to a shoulder strap. This utility model also relates to a backpack. Background Technology

[0002] Baby carriers are baby products used to hold a baby in your arms. Using a baby carrier frees up your hands while holding a baby, making them popular with consumers.

[0003] For example, Chinese utility model patent CN212438039U, published on February 2, 2021, discloses a combined buckle-type baby carrier, which includes a waist belt body and a carrier body. The front end of the waist belt body is sewn with a shoulder strap, and the carrier body is sewn to the middle of the front end of the waist belt body, with the carrier body located outside the shoulder strap. A first buckle is sewn to the middle of the shoulder strap. This utility model sews the carrier body to the end of the waist belt body and adds a shoulder strap component to form a baby support platform, making it convenient to carry the baby on one's body. The waist belt body and the shoulder strap form an overall load-bearing foundation. A third buckle is added to the side of the carrier body to connect with the side strap and the side wall of the shoulder strap, which can limit the baby's position and prevent the baby from falling off the side of the carrier body, improving the safety of the baby carrier. The buckle component is easy to disassemble, avoiding the traditional straps that are directly tied to the body, reducing the difficulty of disassembly and fixation, and is easy to adjust.

[0004] Existing shoulder straps include a fabric layer formed into a tubular structure, within which a foam body made of foamed material is enclosed. In this technology, the foam body is formed through integral foaming; therefore, the sides of the foam body along its length are not sewn to the fabric layer. Otherwise, compression near the seams would impair the foam body's shock-absorbing function. In this technology, the foam body is not sewn to the fabric layer. Because the foam body is not fixed, its position relative to the fabric layer is prone to change. Utility Model Content

[0005] The purpose of this invention is to provide a shoulder strap that can be sewn and fixed without affecting its shock-absorbing function.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A shoulder strap includes a fabric layer and an elastomer. The elastomer includes a support and a breathable elastic block. The support has a sheet-like structure and a through hole. The breathable elastic block is disposed at the through hole and protrudes from the lower surface of the support.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the bracket is connected to the fabric layer, and the breathable elastic block includes several breathable elastic units, and the breathable elastic unit includes several rods arranged according to the spatial three-dimensional ridge lines.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: there are several through holes on the bracket, and each through hole is provided with a breathable elastic block. The through holes are distributed at intervals along the extension direction of the bracket, and there is a gap between the lower part of two adjacent breathable elastic blocks that are lower than the bracket.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the upper parts of two adjacent breathable elastic blocks that are higher than the support are connected together by a number of breathable elastic units.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the inner side of the breathable elastic block is thinner than the outer side of the breathable elastic block.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0025] In the description of this embodiment, the directional terms "outer side" and "inner side" are based on the width direction of the baby carrier. The direction closer to the side of the baby carrier is the outer side, and the direction closer to the middle of the baby carrier is the inner side.

[0026] This utility model discloses a baby carrier, including a front panel 1, shoulder straps 2, and waist belt 3. The lower end of the front panel 1 is connected to the waist belt 3, and the upper end of the front panel 1 is connected to the shoulder straps 2. The lower end of the shoulder straps is connected to the front panel through a strap body 21. The front panel 1 is used to construct a cabin 4 for the baby.

[0027] The baby carrier of this utility model also includes elastically bendable reinforcing blocks 5, which are provided on the lower left 16 and lower right 17 of the front piece 1. In this utility model, the lower left 16 and lower right 17 of the front piece 1 are used to support the baby's legs during use. As shown in the figure, the lower left 16 and lower right 17 of the front piece correspond to the bottom of the seat 4. The support of the elastically bendable reinforcing blocks 5 is greater than that of the material of the front piece 1. Specifically, the elastically bendable reinforcing blocks 5 can bend and deform under the weight of the baby's legs, and at the same time, they have a certain load-bearing capacity. These elastically bendable reinforcing blocks 5 are made of non-fabric materials. Typically, the elastically bendable reinforcing blocks 5 are located within the area of ​​the front piece 1.

[0028] In this invention, since the elastically bendable reinforcing block 5 has a supporting function, when the baby sits in the seat 4, the lower left part 16 and the lower right part 17 of the front piece 1 can resist the lower left part 16 and the lower right part 17 of the front piece 1 from shrinking towards the middle position of the front piece 1 under the action of the elastically bendable reinforcing block 5, thereby effectively supporting the baby's legs.

[0029] In this embodiment, the lower end of the front panel 1 connects to the waist belt 3 at a height that is higher on the outer side than on the inner side, thus creating a lower-inner-higher bottom for the seat 4. The flexible reinforcing block 5, in its bent state, keeps the lower left and right portions 16 and 17 of the front panel 1 higher on the outer side than on the inner side. When the infant sits in the seat 4, the flexible reinforcing block 5 supports the lower left and right portions 16 and 17 of the front panel 1. When the infant's leg weight and leg strength are applied to the lower left and right portions 17, it prevents them from converging towards the center of the front panel 1, ensuring the seat 4 is used in an extended state. This effectively maintains the lower-inner-higher bottom of the seat, allowing the infant's knees to remain relatively high, thus maintaining an M-shaped sitting posture. This reduces outward pulling on the infant's hip joint, effectively preventing hip dislocation and promoting hip joint development. Understandably, the flexible bending reinforcement block 5 has a stretching effect on the lower left 16 and lower right 17 of the front piece 1, so that the entire front piece can be made of breathable materials such as bread fabric or mesh fabric.

[0030] In this embodiment, the flexible reinforcing block 5 is stacked with the front piece 1. Compared to the prior art, a flexible reinforcing block 5 structure is added to the existing front piece 1 of the baby carrier. In this embodiment, the flexible reinforcing block 5 is located on the outer side of the front piece 1. Of course, as another implementation structure, the flexible reinforcing block 5 can also be used as an inner layer structure of the front piece 1.

[0031] In this embodiment, the flexible reinforcing block 5 includes an elastic breathable body portion 6 and an edge portion 7 disposed around the periphery of the elastic breathable body portion 6. The edge portion 7 is fixedly connected to the front piece 1 and has a sheet-like structure. In this embodiment, the elastic breathable body portion 6 has a plurality of first breathable elastic units, each of which includes a plurality of rods arranged along the edges of a cube. The edge portion 7 serves as an excess edge and is sewn onto the front piece 1, thereby allowing the flexible reinforcing block 5 to be sewn to the lower left portion 16 and the lower right portion 17. In this embodiment, the rod distribution structure in the first breathable elastic unit provides good breathability for the flexible reinforcing block 5. When the front piece 1 is made of a breathable mesh fabric or bread fabric, the addition of the flexible reinforcing block 5 will not affect the overall breathability of the baby carrier. In this invention, the flexible reinforcing block 5 is made of soft plastic using 3D printing.

[0032] In this embodiment, the shoulder strap 2 includes a fabric layer 8 and an elastomer 9, wherein the elastomer 9 includes a support 10 and a breathable elastic block 11. The breathable elastic block 11 has good elasticity and can fully contact the human shoulder, improving comfort. The support 10 has a sheet-like structure and is provided with through holes 14. The breathable elastic block 11 is located at the position of the through hole 14. The breathable elastic block 11 located at the position corresponding to the through hole 14 protrudes from the lower surface of the support 10. The support 10 is connected to the fabric layer 8. In the structure of the elastomer 9, the thickness of the support 10 is less than the thickness of the elastic block, and it can be sewn together with the fabric layer 8 at the position of the support 10. In other embodiments, the fabric layer can also cover the elasticity, and the fabric layer and the support are not sewn together. In this utility model, the elastomer adopts the structure of support 10 and breathable elastic block 11. The breathable elastic 11 mainly plays a role in shock absorption, while the support 10 can be used to be sewn and fixed to the fabric layer 8. After the support is sewn to the fabric layer 8, the seam will not cause the air elastic block 11 to be compressed in the thickness direction, thus not affecting the shock absorption function of the air elastic block 11.

[0033] In this embodiment, the breathable elastic block 11 includes several breathable elastic units 12, and each breathable elastic unit 12 includes several rods 13 arranged along the edges of a cube. The rods 13 in the first breathable elastic unit have a distribution structure that allows the elastically bent reinforcing block 5 to have good permeability.

[0034] As shown in the figure, there are several through holes 14 on the bracket 10. The through holes 14 are distributed at intervals along the extension direction of the bracket 10. There is a gap 15 between the lower parts of two adjacent breathable elastic blocks 11 that are lower than the bracket 10. Due to this structure, the elastic body 9 has good overall flexibility, can be easily bent and fit the human shoulder better, increases the contact surface between the shoulder strap 2 and the human shoulder strap 2, and disperses the force of the shoulder strap on the shoulder.

[0035] As shown in the figure, the upper parts of two adjacent breathable elastic blocks 11 above the support 10 are connected together by several breathable elastic units 12. This structure can further enhance the overall strength of the elastomer 9.

[0036] In this invention, the elastomer 9 is made of soft plastic through 3D printing. It should be noted that the first breathable elastic unit in the elastically bendable reinforcing block 5 and the breathable elastic unit 12 in the elastomer 9 can have the same structure.

[0037] As shown in the figure, the lower end of the shoulder strap 2 is connected to the front piece 1, and the inner side 19 of the breathable elastic block is thinner than the outer side 20 of the breathable elastic block. In practical application, the shoulder strap 2 is wrapped around the armpit and connected to the front piece 1. The shoulder strap 2 forms a twist, and the structure of the inner side of the elastomer 9 is thinner, so that it makes integral contact with the human shoulder in the width direction of the shoulder strap 2, avoiding contact between the support 10 of the elastomer 9 and the human shoulder. This allows the shock absorption effect of the breathable elastic block 11 to be fully utilized, thereby providing wearing comfort.

[0038] It should be noted that the shoulder straps in the above embodiments can be used not only in baby carriers but also in products such as backpacks, school bags, and travel backpacks. Typically, a backpack consists of a body and shoulder straps, which are connected. The body is used to store items.

[0039] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
