Description

Technical Field

[0001] The utility model relates to the technical field of stationery, in particular to a spine-protecting backpack. Background Art

[0002] A schoolbag is a backpack used by students to carry textbooks and stationery in their daily lives. A common schoolbag is a backpack with two straps on the back for buckling onto the shoulders. When a person carries a backpack on their shoulders while moving, the shoulder straps are the primary means of bearing the backpack's weight. When the person is stationary, the pressure exerted by the shoulder straps on the shoulders is close to the weight of the backpack. However, when a person is walking, the shoulders experience vertical acceleration, and the shoulder straps are generally inelastic, causing the shoulders and the backpack to move almost synchronously. This results in the pressure exerted by the shoulder straps on the shoulders being greater than the weight of the backpack. Carrying a heavy backpack for an extended period of time can easily lead to shoulder strain.

[0003] During the process of realizing the present invention, the inventors found that currently, when a backpack is loaded with heavy objects, the weight is easily dispersed, which causes pressure on the user's shoulders and waist. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a spine protection backpack that overcomes the above problems or at least partially solves the above problems.

[0005] In a first aspect, an embodiment of the present invention provides a back-protecting backpack, comprising: a backpack body, wherein items can be stored inside the backpack body;

[0006] Two shoulder straps are symmetrically arranged on both sides of the back of the backpack body;

[0040] Please refer to the attached Figure 2 , the embodiment of the utility model provides a spine protection backpack, comprising: a backpack body 10, the interior of the backpack body 10 can store items;

[0041] Two shoulder straps 16 are symmetrically arranged on both sides of the back of the backpack body 10;

[0042] A waist belt 17 and an expansion bag 11, which are respectively installed at the bottom ends of both sides of the back of the backpack body 10;

[0043] The backpack further includes a spine protection assembly, which includes a first spine protection member 12 provided on the back of the backpack body 10;

[0044] The second spine protector 13 , the first spine protector 12 and the second spine protector 13 are movably connected, and the second spine protector 13 can be attached to the bottom of the backpack body 10 or the back of the backpack body 10 .

[0045] It is understandable that current backpacks are prone to weight dispersion when carrying heavy objects, causing pressure on the user's shoulders and waist.

[0046] In an embodiment, a first spine guard 12 for vertical support is provided on the back of the backpack body 10. The first spine guard 12 is made of a hard material to ensure that pressure dispersion can be effectively prevented. At the same time, a second spine guard 13 is provided at the bottom of the backpack body 10. The second spine guard 13 is movably connected to the first spine guard 12 and can swing around the connection position. That is, when the backpack needs to carry heavier items, the second spine guard 13 is attached to the bottom of the backpack and connected to the second spine guard 13 through the first spine guard 12, effectively concentrating gravity on the second spine guard 13 and the first spine guard 12. This effectively protects the spine even when carrying heavy items, reduces the pressure on the user and reduces shoulder strain.

[0047] When in use, the backpack's main body 10 can store items, and the back of the backpack is provided with shoulder straps 16, allowing the user to carry the backpack 10 on their back. The first back protector 12 on the back of the backpack 10 and the second back protector 13 on the bottom of the backpack 10 work together to effectively reduce the effect of the weight of the items inside on the waist, thereby effectively protecting the back.

[0048] Please refer to the attached Figure 3 and 4 In a further embodiment, the first spine guard 12 includes a guard plate 120, which is provided on the back of the backpack body 10 for supporting the backpack body 10; and

[0049] At least two back pads 122 are symmetrically arranged on a side of the guard plate 120 away from the backpack body 10 .

[0050] As can be understood, the first spine protector 12 is configured as a guard plate 120 and a back pad 122. The back pad 122 is fixed to the side of the guard plate 120. When the guard plate 120 is placed on the back of the backpack body 10, the guard plate 120 provides support through its rigid structure. Furthermore, the back pad 122, made of a rigid material, is placed on the guard plate 120 and supports the user's back, thereby protecting the waist.

[0051] In one embodiment, the number of the back pads 122 is two, and the back pads 122 are symmetrically arranged along the vertical direction of the guard plate 120, that is, the two back pads 122 are arranged on both sides, and the back is made of the rigid back pad 122, which effectively plays a protective role; in another embodiment, the number of the back pads 122 is four, and the back pads 122 are symmetrically arranged along the vertical direction of the guard plate 120, that is, the four back pads 122 are arranged on both sides, and the back is made of the rigid back pad 122, which effectively plays a protective role; in another embodiment, the number of the back pads 122 is six, and the back pads 122 are symmetrically arranged along the vertical direction of the guard plate 120, that is, the six back pads 122 are arranged on both sides, and the back is made of the rigid back pad 122, which effectively plays a protective role.

[0052] In a further embodiment, the guard plate 120 and the back pad 122 are carbon fiber plates.

[0053] It can be understood that in order to reduce the pressure of the backpack on the waist, the embodiment uses a structural plate made of carbon fiber for the guard plate 120, and the back pad 122 is also made of carbon fiber. Here, the back pad 122 is made into a raised structure, that is, the back pad 122 is a raised structure that cannot be recessed, so that it can play a supporting role when in use.

[0054] In a further embodiment, a filler is provided inside the back pad 122 .

[0055] As can be understood, in order to increase the hardness of the back pad 122, in this embodiment, the back pad 122 is configured as a hollow structure, and a filler is placed in the internal cavity to provide support. Of course, the back pad 122 can also be configured as an integral structure, that is, the interior is also filled with the same material as the back pad 122 to form an integral structure, ensuring that the back pad 122 can support the waist and the backpack and prevent the back pad 122 from sinking.

[0056] Please refer to the attached Figure 4In a further embodiment, the second spine protector 13 includes a support layer 132 for supporting heavy objects; a wrapping layer 131 wrapped around the outside of the support layer 132, and the wrapping layer 131 is movably connected to the backpack body 10.

[0057] As will be appreciated, the second spine protector 13 is configured as at least two parts, including a support layer 132 and a wrapping layer 131. The wrapping layer 131 is disposed outside the support layer 132 to enhance the aesthetics of the exterior and connect to the interior of the backpack body 10 via the wrapping layer 131. This allows the second spine protector 13 to be folded and attached to the back or bottom of the backpack body 10. In other words, the position of the second spine protector 13 can be changed depending on the backpack's usage. When heavier items are needed, the second spine protector 13 is attached to the bottom of the backpack body 10, and the second spine protector 13 and the first spine protector 12 cooperate to provide spinal protection.

[0058] Please refer to the attached Figure 3 , the embodiment further, the spine protection backpack further includes a first quick-connector 130, which is provided at an end of the second spine protection member 13 away from the connection position;

[0059] The second quick connector 121 is disposed inside the backpack body 10 and corresponds to the first quick connector 130 .

[0060] It can be understood that in order to prevent the problem of poor fitting when the second spine protector 13 is fitted to the back of the backpack main body 10, causing items to enter between the second spine protector 13 and the back of the backpack main body 10, resulting in poor user experience, in this embodiment, a first quick connector 130 is provided on the second spine protector 13, and a second quick connector 121 for the first quick connector 130 is provided on the back of the backpack main body 10. By connecting the first quick connector 130 and the second quick connector 121, the second spine protector 13 can be effectively fitted to the backpack main body 10.

[0061] Please refer to the attached Figure 3 In a further embodiment, the first quick connector 130 and the second quick connector 121 are magnetic parts or Velcro.

[0062] It is understood that in some embodiments, the first quick connector 130 is a magnet and the second quick connector 121 is a magnet; in other embodiments, the first quick connector 130 is a metal sheet and the second quick connector 121 is a magnet; in still other embodiments, the first quick connector 130 is a Velcro and the second quick connector 121 is a Velcro. In this way, the second spine protector 13 can be quickly connected to or separated from the back of the backpack body 10.

[0063] Please refer to the attached Figure 1 and 5 In the embodiment, the spinal protection assembly further includes a first adjustment strap 18, which is arranged along the shoulder strap 16, and one end of the first adjustment strap 18 is connected to the top of the backpack body 10 through an adjustment buckle, and the other end is connected to the shoulder strap 16.

[0064] As can be understood, in order to prevent the backpack from not fitting properly against the user's back and thus affecting the waist, an embodiment is provided with a first adjustment strap 18 at the upper portion of the backpack along the shoulder strap 16. One end of the first adjustment strap 18 is connected to the top of the backpack via an adjustment buckle, and the other end is connected to the shoulder strap 16. The first adjustment strap 18 passes through the adjustment buckle and can be adjusted by the adjustment buckle to prevent the upper portion of the backpack from moving away from the user's back, i.e., to bring the backpack closer to the user's back, effectively achieving the purpose of protecting the spine.

[0065] Please refer to the attached Figure 2 In the embodiment, the spine-protecting book further includes a second adjustment strap 14, which is arranged at the upper part of both sides of the backpack body 10, and the two ends of the second adjustment strap 14 are respectively connected to the backpack body 10, and a connecting buckle 140 is also provided in the middle of the second adjustment strap 14.

[0066] It can be understood that the second adjustment straps 14 are arranged at the upper part of both sides of the backpack body 10. By adjusting the connecting buckles 140 on the second adjustment straps 14, the backpack can be further restricted from being moved away from the user's back, effectively achieving the purpose of protecting the spine.

[0067] Please refer to the attached Figure 2 In a further embodiment, the spine-protecting book further includes a decorative bag 15 , and the decorative bag 15 is detachably connected to the backpack body 10 .

[0068] It can be understood that in order to increase the decoration of the backpack, in the embodiment, a decorative bag 15 is detachably provided on the upper part of the spine protection bag away from the back, and a pattern sticker is provided on the back of the decorative bag 15 to be detachably connected to the backpack.
