Description

A cross-shaped weight-reducing backpack Technical Field

[0001] This utility model relates to the field of backpack technology, specifically a cross-type weight-reducing backpack. Background Technology

[0002] In everyday life, backpacks have become an indispensable tool for people, whether it is for students to carry heavy textbooks and numerous stationery items to school every day, or for travelers to carry various luggage and supplies on their journeys.

[0003] However, traditional backpacks have significant shortcomings in terms of design structure and actual user experience. When carrying a traditional backpack, the weight is excessively concentrated on the shoulders. When people carry heavy items for a long time, the shoulders not only have to bear the entire weight of the items, but also, due to the narrow stress area, they are prone to shoulder muscle soreness and fatigue. This may even have irreversible negative effects on spinal development and body posture. Therefore, a cross-type weight-reducing backpack has been proposed.

[0004] Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cross-type weight-reducing backpack, which has the advantages of increasing the force-bearing area to achieve the effect of weight reduction. It solves the problem that the force of traditional backpacks is mainly concentrated on the shoulders, and the shoulders bear huge pressure when carrying heavy objects for a long time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cross-type weight-reducing backpack, including a back panel, a weight-reducing back plate provided on the front side of the back panel, weight-reducing waist belts provided at the bottom of both sides of the weight-reducing back plate, two shoulder strap extension tension bands cross-arranged on the side of the weight-reducing back plate near the back panel, two fixing pieces fixedly installed on the side of the weight-reducing back plate near the back panel, the bottom of each of the two shoulder strap extension tension bands being fixedly connected to the corresponding fixing pieces, and shoulder straps provided at the top of each of the two shoulder strap extension tension bands.

[0007] Furthermore, the periphery of the weight-reducing back panel is sewn to the front side of the back panel, and the top of the weight-reducing back panel has two channels that are adapted to the width of the shoulder straps.

[0008] Furthermore, each of the two shoulder strap extension straps has a D-ring buckle at its top, and both shoulder strap extension straps are connected to their corresponding shoulder straps via the D-ring buckle. The ends of both shoulder straps are fixedly connected to the back panel for weight reduction.

[0009] Furthermore, each of the two shoulder straps is provided with a connecting strap on its opposite side, and a first buckle is provided between the two connecting straps.

[0010] Furthermore, a second buckle is provided between the two weight-reducing waist belts.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] This cross-shaped weight-reducing backpack effectively distributes the weight that was originally concentrated on the shoulders to the waist through its weight-reducing back panel, shoulder strap extension straps, and weight-reducing waist belt. This greatly reduces the stress on the shoulders. The shoulder strap extension straps are arranged in a cross shape and are firmly connected to the weight-reducing back panel through fixing plates, forming a scientific force transmission structure. This allows the weight of the backpack to be distributed more evenly on the user's back and waist, thereby improving carrying comfort. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4. In this embodiment, a cross-type weight-reducing backpack includes a back panel 1. A weight-reducing back plate 2 is provided on the front side of the back panel 1. Weight-reducing waist belts 3 are provided at the bottom of both the left and right sides of the weight-reducing back plate 2. Two shoulder strap extension tension bands 4 are cross-arranged on the side of the weight-reducing back plate 2 near the back panel 1. Two fixing pieces 5 are fixedly installed on the side of the weight-reducing back plate 2 near the back panel 1. The bottom of each of the two shoulder strap extension tension bands 4 is fixedly connected to the corresponding fixing piece 5. Shoulder straps 6 are provided at the top of each of the two shoulder strap extension tension bands 4.

[0020] Back panel 1 serves as the basic load-bearing frame of the entire backpack. A weight-reducing back panel 2 is set on the front side of the back panel 2. The weight-reducing back panel 2 acts as a core hub, playing a key role in support and force transmission. Weight-reducing waist belts 3 are installed on the bottom of the left and right sides of the weight-reducing back panel 2. When the user wears the backpack, the weight-reducing waist belts 3 can transfer some of the weight from the shoulders to the waist, distributing the overall force.

[0021] On the side of the back panel 2 near the back panel 1, two shoulder strap extension bands 4 are arranged in a cross pattern. In order to achieve a stable connection between the shoulder strap extension bands 4 and the back panel 2, two fixing pieces 5 are fixedly installed on the side of the back panel 2 near the back panel 1. The bottom of the two shoulder strap extension bands 4 is firmly connected to the corresponding fixing pieces 5, forming a stable force-bearing structure. When the shoulder straps 6 are worn on the body, the two fixing pieces 5 are the force-bearing points. The length of the shoulder straps 6 is adjusted by the D-ring buckle 7, and the force-bearing points are transferred downward to increase the force-bearing area. The fixing pieces 5 transfer the force-bearing points to the waist belt 3 to achieve the effect of reducing the load.

[0022] Two channels adapted to the width of the shoulder straps 6 are reserved at the top of the back panel 2. These two channels not only ensure that the shoulder straps 6 can pass through smoothly, but also limit the shoulder straps 6 to prevent them from moving left and right.

[0023] By setting connecting straps 8 on opposite sides of the two shoulder straps 6 and setting a first buckle 9 between the two connecting straps 8, when the user needs to wear the backpack more securely, the two connecting straps 8 can be connected together by the first buckle 9 to prevent the shoulder straps 6 from slipping during exercise. The second buckle 10 set between the two weight-reducing waist belts 3 makes it convenient for the user to quickly put on and take off the weight-reducing waist belts 3, and at the same time, the tightness of the weight-reducing waist belts 3 can be flexibly adjusted according to their own waist size.

[0024] Utilizing the scientific principle of shifting the stress point downwards, the pressure originally concentrated on the shoulders is transferred and dispersed layer by layer through the shoulder strap extension strap 4, the back plate 2, and the waist belt 3, effectively increasing the overall stress area. From the actual usage effect, it can significantly reduce the pressure on the user's shoulders, bringing the user a more relaxed and comfortable carrying experience. Whether in daily study, work, or travel, it can demonstrate excellent performance and advantages.

[0025] When implementing this procedure, please follow these steps:

[0026] 1) First, place the backpack's back panel 2 close to your back, then put your hands through the two shoulder straps 6 and place the shoulder straps 6 on your shoulders. At this time, the shoulder straps 6 will hang down naturally through the channel at the top of the back panel 2.

[0027] 2) Then check the D-ring buckles 7 at the top of the two shoulder strap extension bands 4. Adjust the length of the shoulder strap 6 according to your own comfort needs by pulling up the movable part of the D-ring buckle 7 and moving the shoulder strap 6 up and down. After adjusting to a suitable length, loosen the movable part of the D-ring buckle 7 to fix the shoulder strap 6. At this time, the stress point will change with the adjustment of the shoulder strap 6 length. In this way, the stress point is moved down to prepare for subsequent stress distribution.

[0028] 3) Then pick up the connecting straps 8 on the opposite side of the two shoulder straps 6, and align the first buckle 9 to connect the two connecting straps 8 together;

[0029] 4) Finally, wrap the two weight-relief belts 3 around the sides of the body and pull them to the front. Find the second buckle 10 between the two weight-relief belts 3 and fasten them together. Adjust the position of the second buckle 10 according to your waist size so that the weight-relief belts 3 fit the waist.

[0030] In summary, this cross-type weight-reducing backpack, through its weight-reducing back panel 2, shoulder strap extension tension bands 4, and weight-reducing waist belt 3, effectively distributes the weight originally concentrated on the shoulders to the waist, greatly reducing the stress on the shoulders. The shoulder strap extension tension bands 4 are arranged in a cross shape and are firmly connected to the weight-reducing back panel 2 through fixing plates 5, forming a scientific force transmission structure, which allows the weight of the backpack to be more evenly distributed on the user's back and waist, thereby improving carrying comfort.
