Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to a double-shoulder backpack. Background Art

[0002] Backpacks are one of the commonly used daily necessities in people's daily lives, which usually include single-shoulder backpacks, double-shoulder backpacks, cross-body backpacks, etc. Since people usually need to fix the backpack on the body to bear the weight of the items loaded in the backpack, the user comfort of the backpack is mainly reflected in the magnitude of the back pressure and the comfort of the body parts in contact with the backpack during the load process (including breathability, heat dissipation, etc.).

[0003] In the prior art, various styles of backpacks are known. In addition to the design considerations in terms of aesthetics, various backpack styles have also been proposed for alleviating the back pressure. However, these known backpacks are either too complex in structure and have a high manufacturing cost, or lack effective dispersion of pressure and heat, resulting in uneven load stress on the shoulders and waist, etc. of the user during the use of the backpack, and especially in hot weather, the shoulders and back are stuffy, thus greatly reducing the user comfort of the backpack.

[0004] Therefore, it is necessary to propose a backpack with a simple structure and greatly improved user comfort. Summary of the Utility Model

[0005] The purpose of the utility model is to solve at least one of the above problems and / or other problems existing in the prior art.

[0006] To this end, the utility model provides a double-shoulder backpack, which includes a backpack body and two shoulder straps. The backpack body includes a back panel designed to be in contact with the user's back. Three independent and separated mesh pads are arranged on the back panel. The three mesh pads all protrude from the surface of the back panel and include a first mesh pad and a second mesh pad symmetrically arranged about the vertical center line of the back panel in the upper part of the back panel and a third mesh pad centrally arranged in the lower part of the back panel, so as to provide support for the user's back through three mesh pad areas. Among them, a heat dissipation space is formed between the three mesh pads. The heat dissipation space includes a first channel part defined at the middle area of the back panel, a second channel part located between the first mesh pad and the second mesh pad, and a third channel part and a fourth channel part located on both sides of the third mesh pad. All the channel parts are communicated with each other. Among them, the width of the first channel part is equal to the width of the back panel.

[0007] As an implementation manner, each of the first mesh pad and the second mesh pad at least includes a first edge, a second edge, and a third edge that are connected to each other, wherein the first edge is sewn to the side surface of the backpack body; the second edge is sewn to the back panel and has a first curved profile that arches toward the center of the back panel, and the third edge is sewn to the back panel and has a second curved profile that arches toward the center of the back panel.

[0008] As an implementation manner, the third mesh pad is in the shape of an isosceles trapezoid.

[0009] As an implementation manner, the shoulder strap includes a shoulder strap body in an S shape.

[0010] As an implementation manner, a first chest buckle connector is provided on the first shoulder strap of the two shoulder straps at a position close to the user's chest, and a second chest buckle connector that is snap-fitted with the first chest buckle connector is provided on the second shoulder strap of the two shoulder straps at a position close to the user's chest.

[0011] As an implementation manner, a first waist buckle connecting strap and a second waist buckle connecting strap are respectively provided on both sides of the third mesh pad at the lower part of the back panel. One end of each waist buckle connecting strap is sewn to the side surface of the backpack body adjacent to it, and a waist buckle connector is provided at the other end.

[0012] As an implementation manner, elastic cotton with breathable mesh holes is provided on the side of the first waist buckle connecting strap and the second waist buckle connecting strap that abuts against the user.

[0013] As an implementation manner, the three mesh pads include elastic cotton with breathable mesh holes.

[0014] As an implementation manner, elastic cotton with breathable mesh holes is provided on the side of the shoulder strap that abuts against the user.

[0015] As an implementation manner, a brand logo is provided on the surface area of the back panel that defines the first channel portion and / or on the side of at least one of the shoulder straps that is away from the user.

[0016] For the double-shoulder backpack according to the present utility model, by only providing three mutually independent mesh pads, three-point support can be provided for the user's back to make the backpack fit the back better, so as to more effectively and evenly disperse the load pressure of the backpack, reduce the burden on the human spine, and also make the user's waist and back straighter. Since the mesh pads are in the form of elastic cotton with breathable mesh holes, good breathability, cushioning property, and heat dissipation property can be provided. In addition, since the three mesh pads are arranged at intervals from each other, a relatively large open heat dissipation space is defined, making it easier for the heat of the user's back to dissipate, thereby avoiding the accumulation of heat at the user's back and greatly improving the user's comfort.

Therefore, the following aspects, features, embodiments and advantages are for illustrative purposes only and should not be regarded as elements or limitations of the claims, unless expressly recited in the claims.

[0023] In the following text, terms such as "first", "second", etc. are used to describe the elements of the present application. These terms are only used to distinguish the various elements and not to limit the nature, sequence or number of these elements. The terms "comprising" and "having" are used to mean an open inclusion, and mean that there may be additional elements / components in addition to the listed elements / components.

[0024] Figure 1 A rear view of a backpack according to a specific embodiment of the present utility model is shown. The backpack 1 includes a backpack body and two shoulder straps, and the backpack body includes a back panel 2 designed to be in contact with the user's back. Particularly referring to Figure 2, three mesh pads 21, 22, 23 are arranged on the back panel 2, which are independent and separated from each other. The three mesh pads include or use elastic cotton with breathable mesh holes to achieve better ventilation, cushioning and heat dissipation. The three mesh pads 21, 22, 23 all protrude from the back panel surface and include a first mesh pad 21 and a second mesh pad 22 symmetrically arranged on the upper part of the back panel 2 about the vertical center line O of the back panel, and a third mesh pad 23 arranged in the middle of the lower part of the back panel, so as to provide support for the user's back through the three mesh pad areas.

[0025] This arrangement is very advantageous because the three mesh pads can provide three-point support for the user's back so that the backpack fits the back more closely, thereby allowing the load pressure of the backpack to be more effectively and evenly distributed, reducing the burden on the human spine, and making the user's back straighter. This is also more beneficial for the spinal development of adolescents. In addition, a heat dissipation space is formed between the three mesh pads (i.e., the back panel area without mesh pads). The heat dissipation space includes a first channel portion 24 (such as a middle area) defined in the middle area of ​​the back panel (the middle area here does not emphasize the absolute middle position of the back panel, but is intended to indicate the portion between the first and second mesh pads and the third mesh pad that is roughly located in the middle of the back panel). Figure 2 The second channel portion 25 is located between the first mesh pad 21 and the second mesh pad 22, and the third channel portion 26 and the fourth channel portion 27 are located on both sides of the third mesh pad 23. These channel portions are interconnected, and the first channel portion 24 occupies most of the entire heat dissipation space. Its width (i.e., the width along the direction transverse to Figure 2 The width of the back plate 2 is equal to the width of the back plate 2. Thus, the heat accumulated on the back of the user can be ventilated to a great extent and air flow can be provided. Therefore, thanks to the favorable mesh pad arrangement of the backpack of the utility model, the user's comfort is greatly improved.

[0026] Continue to see Figure 2 , each of the first mesh pad 21 and the second mesh pad 22 at least includes a first edge 21a, 22a, a second edge 21b, 22b and a third edge 21c, 22c connected to each other, wherein the first edge is sewn to the side of the backpack body; the second edge is sewn to the backboard and has a first curved profile arched toward the center of the backboard, and the third edge is sewn to the backboard and has a second curved profile arched toward the center of the backboard. It should be noted that "arched toward the center of the backboard" here is only intended to emphasize the approximate direction of the curved convex portion of the curved profile, and is not intended to require that the curved profile must extend completely in alignment with the center of the backboard. The design of this curved profile is in line with the ergonomic design concept, which can provide effective support for the area near the shoulder.

[0027] The third mesh pad 23 is disposed at a position corresponding to the human lumbar spine and is generally in the shape of an isosceles trapezoid. This setting enables the pressure to be dispersed as much as possible with a relatively small area.

[0028] Continue to refer to Figure 3 , a first chest buckle connecting member 31 is provided at a position of the first shoulder strap 3a of the two shoulder straps close to the user's chest, and a second chest buckle connecting member 32 that is snap-fitted with the first chest buckle connecting member 31 is provided at a position of the second shoulder strap 3b of the two shoulder straps close to the user's chest. Each shoulder strap includes a shoulder strap body in an S shape. An elastic cotton with breathable mesh holes is provided on the side of the shoulder strap that abuts against the user.

[0029] Continue to refer to Figure 4 , a first waist buckle connecting strap 4a and a second waist buckle connecting strap 4b are respectively provided on both sides of the third mesh pad 23 at the lower part of the back panel. One end of each waist buckle connecting strap is sewn to the side surface of the backpack body adjacent thereto, and waist buckle connecting members 41, 42 are provided at the other end. An elastic cotton with breathable mesh holes is provided on the side of the waist buckle connecting strap that abuts against the user.

[0030] In addition, a brand logo is provided on the surface area of the back panel that defines the first channel portion 24 and / or on the side of at least one of the shoulder straps away from the user, for more aesthetic and promotional effects.

[0031] For those skilled in the art, various modifications and variations can be made to the embodiments disclosed above without departing from the scope or spirit of the present invention. Based on the practice of the present invention disclosed in this specification, other embodiments of the present invention will be apparent to those skilled in the art. This specification and the examples disclosed therein should be considered merely illustrative, and the true scope of the present invention is defined by the appended claims and their equivalents.
