Description

Technical Field

[0001] The present invention relates to the technical field of backpacks, in particular to a backpack with an adjustable strap structure. Background Art

[0002] With the development of society and the increasing richness of life, backpacks have become essential tools for people when going out. When people carry a backpack, the width and thickness of the straps will affect the comfort of use. The wider and thicker the straps, the smaller the pressure on the shoulders, increasing the comfort of people's shoulders. However, the width and thickness of the straps of existing backpacks are generally fixed and cannot be adjusted, so that people cannot flexibly adjust the straps according to the weight of the items in the backpack, resulting in a relatively large pressure on the shoulders, poor comfort, and also prone to potential health hazards to the shoulders.

[0003] To overcome the above technical problems, the inventor of the present invention designed a backpack with an adjustable strap structure, and this case was thus born. Summary of the Invention

[0004] To solve the above problems, the technical solution of the present invention is as follows:

[0005] A backpack with an adjustable strap structure, comprising a backpack body and straps, and an adjusting component for independently adjusting the width and thickness of the straps is provided on the straps.

[0006] Further set as: The adjusting component is telescopically connected to the straps.

[0007] Further set as: The adjusting component is in a stacked state to form a stacked layer. One side of the adjusting component is connected to the straps, and the other side is movably pulled to open the stacked layer, and the stacked layer extends beyond the width of the straps.

[0008] Further set as: The middle part of the adjusting component is arranged in the middle of the straps for stacking. The two sides of the adjusting component are respectively folded towards the middle, and the number of layers of the stacked layer is greater than 2 layers; when opened outward, the two sides of the adjusting component respectively extend beyond the left and right sides of the straps.

[0009] Further set as: The connection method between the adjusting component and the straps is sewing, and the adjusting component is opened and closed by folding.

[0010] Further set as: One side of the adjusting component is rotatably connected to the straps, and the other side is movably extended beyond the width of the straps.

[0011] Further set as: When there are two adjusting components, they are respectively arranged on the left and right sides of the straps. After being opened, one side of the adjusting component is connected to one side edge of the straps, and the other side extends beyond the straps.

[0012] Further set as: The connection mode between the adjusting component and the strap is buckling, and the adjusting component is opened and closed by rotation.

[0013] Further set as: There is a storage cavity on the strap, and the adjusting component is placed in the storage cavity when it is closed.

[0014] Further set as: The side of the adjusting component in contact with the human body is provided with an arc surface.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By setting the backpack, the strap, and the adjusting component, the width and thickness of the strap are adjusted through the adjusting component, so that when the human body wears the backpack, the contact area between the strap and the human body is increased, the pressure on the human shoulder is reduced, the thickness of the strap is increased, the strap has a certain buffering effect, and the pressure on the human body is reduced;

[0017] 2. The adjusting component is a retractable design that can be adjusted independently, which is convenient for independently and flexibly adjusting the thickness / width according to the actual weight of the backpack and the pressure feeling.

[0018] 3. By sewing one side of the adjusting component on the strap and the other side in a folded and overlapping state to form an overlapping layer, the thickness can be adjusted better; when in use, one side of the adjusting component is connected to the strap, and the other side is pulled open in a movable manner, and the overlapping layer extends beyond the width of the strap; the number of adjusting components can be flexibly set. For example, if there are two adjusting components, they are respectively placed at a certain distance from the edge in the strap. One side of the adjusting component is fixed to the strap on the side of the middle of the strap, and the other side is overlapped on the strap surface in a combined state. The overlapping layer (the number of layers is not limited, preferably 2-3 layers) thickens the strap, absorbs the pressure of the bag body on the human body to a certain extent, and plays a pressure-reducing effect. When the items in the bag are heavy, the overlapping layer is opened outward, further widening the width of the strap, thereby widening the total contact area between the backpack and the shoulder, and reducing the discomfort caused by excessive local force on the human shoulder;

[0019] 4. By buckling one side of the adjusting component and rotatably connecting it to one side edge of the strap, and the other side extending beyond the strap, the operation is convenient, and the width can be easily increased by only pulling the movable side of the adjusting component; when there are two adjusting components, they are respectively placed on the left and right sides of the strap. When opened, one side of the adjusting component is connected to one side edge of the strap, and the other side extends beyond the strap body, thereby widening the contact area between the backpack and the shoulder, and reducing the discomfort caused by excessive local force on the human shoulder.

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] Embodiment 1 is as follows:

[0035] Reference Figures 1 to 7 Figures 1 to 7 , a backpack with an adjustable strap structure, includes a backpack body 1 and straps 2. There is a storage cavity 3 on the straps 2, and an adjusting component 4 for independently adjusting the width and thickness of the straps 2 is provided on the straps 2. The adjusting component 4 is telescopically connected to the straps 2. When the adjusting component 4 is retracted, it is placed in the storage cavity 3, and when it is unfolded, it extends beyond the width of the straps 2.

[0036] The adjusting component 4 has a connection side connected to the straps 2 and a telescopic side that can be freely adjusted. The number of the adjusting components 4 can also be flexibly designed according to actual needs.

[0037] In this embodiment, the connection method of the connection side of the adjusting component 4 and the straps 2 is stitching, and the telescopic side is opened and retracted by flipping or folding;

[0038] Specifically, as Figure 2 、 3 shown, the adjusting component 4 includes several flipping plates and a rotating shaft provided between adjacent flipping plates. The flipping plates are rotatably connected through the rotating shaft. Among them, the flipping plate located on the innermost side of the straps is fixedly stitched to the straps.

[0039] Or, as Figures 4 to 7 shown, the adjusting component 4 can be a folding type: when retracted, the adjusting component 4 is in a stacked state, forming a stacked layer 5; when opened, one side of the adjusting component 4 is connected to the straps 2, and the other side is pulled out to open the stacked layer 5, and the stacked layer 5 extends beyond the width of the straps 2;

[0040] Specifically, as Figures 4 - 5 shown, when there are two adjusting components 4, they are respectively placed in the straps 2 and close to the middle of the straps 2. One side of the adjusting component 4 close to the middle of the straps 2 is fixed to the straps 2 for stacking, and the other side of the adjusting component 4 is folded towards the side close to the middle of the straps 2 in a folding manner. The number of stacked layers is greater than 2 layers, thickening the thickness of the straps 2, absorbing the pressure of the bag body on the human body to a certain extent, and achieving a pressure relief effect; when feeling pain and excessive pressure on the shoulders when carrying the backpack, open it outwards. The side of the adjusting component 4 far from the middle of the straps 2 extends beyond the width of the straps 2, widening the width of the backpack straps, thereby widening the contact area between the backpack and the shoulders and reducing the discomfort caused by excessive local force on the human shoulders.

[0041] As Figures 6 - 7, when there is one adjusting member 4, the middle part of the adjusting member 4 is arranged in the middle of the shoulder strap 2 for overlapping. The two sides of the adjusting member 4 are folded towards the middle, and the number of overlapping layers is greater than 2 layers (preferably 2 - 3 layers); when the pressure is too high when carrying the backpack, it is opened outward, and the two sides of the adjusting member 4 respectively extend beyond the left and right sides of the shoulder strap 2. In this way, when overlapping, the overlapping piece can thicken the thickness of the shoulder strap 2, absorb the pressure of the bag body on the human body to a certain extent, and achieve the effect of pressure reduction. When the overlapping layer 5 is opened outward, it also widens the width of the shoulder strap 2, thereby widening the contact area between the backpack and the shoulder, and reducing the discomfort caused by excessive local force on the human shoulder.

[0042] Embodiment 2 is as follows:

[0043] The difference from Embodiment 1 is that the connection method between the adjusting member 4 and the shoulder strap 2 is buckling, and the adjusting member 4 is opened and closed by a rotating method. One side of the adjusting member 4 is connected to the side of the shoulder strap 2, and the other side is movably wider than the width of the shoulder strap 2.

[0044] Specifically, as Figure 8 shown, when there is one adjusting member 4, it is arranged on one of the left and right sides of the shoulder strap 2 and is rotatably connected to the shoulder strap 2; when opened, the adjusting member 4 rotates and moves towards any side of the shoulder strap 2, widening the shoulder strap 2, thereby widening the contact area between the backpack and the shoulder, and reducing the discomfort caused by excessive local force on the human shoulder.

[0045] As Figure 9 shown, when there are two adjusting members 4, they are respectively arranged on the left and right sides of the shoulder strap 2. When opened, the adjusting members 4 respectively rotate and move towards the two sides of the shoulder strap 2, widening the shoulder strap 2, thereby further widening the contact area between the backpack and the shoulder, and reducing the discomfort caused by excessive local force on the human shoulder.

[0046] Preferably, an arc-shaped surface is provided on the surface of the adjusting member 4 in contact with the human body to better conform to ergonomics, and the backpack is more comfortable to use.

[0047] The present invention has been described exemplarily above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
