Description

Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to an adjustable backpack. Background Technology

[0002] Backpacks are widely used, from school bags to sports backpacks; they can be seen wherever there are people. The advantage of this type of backpack is that it allows the shoulders to bear the weight, and compared to other types of bags, it doesn't significantly restrict movement, making it very popular.

[0003] Traditional backpacks, such as those with Chinese utility model patent CN103653695A (titled "A Backpack") and Zhonggu utility model patent CN116548721A (titled "A Backpack"), both use two adjustable shoulder straps sewn securely to the back of the bag. While this securely attaches the straps, different people have different body shapes and shoulder widths. When the width between the two shoulder straps of a traditional backpack is fixed, it easily increases discomfort for some users, leading to a rapid decline in backpack sales.

[0004] Therefore, how to design a backpack that is simple in structure, inexpensive, easy to wear, and has adjustable shoulder width is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides an adjustable backpack, which solves the technical problem that the non-adjustable shoulder width of existing backpacks leads to increased user discomfort.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an adjustable backpack, comprising: a bag body, shoulder straps, and a top hook.

[0007] The back of the bag is sewn with an upper hanging strap along its width, and the upper hanging strap has a plurality of hanging holes spaced apart along its length; there are two shoulder straps; the bottom ends of the two shoulder straps are symmetrically sewn to the lower back of the bag; there are two upper hooks, which are sewn to the top of the two shoulder straps respectively, and the two upper hooks can be detachably hooked onto the plurality of hanging holes to increase or decrease the distance between the top ends of the two shoulder straps.

[0008] The beneficial effects of this utility model are: it subverts the traditional connection method of fixing and sewing the shoulder straps of a backpack. First, an upper hanging strap is set on the upper part of the back of the bag body, and then two upper hanging buckles are sewn to the top of the two shoulder straps respectively. Since the upper hanging strap has multiple hanging holes spaced along its length, and since the two upper hanging buckles sewn to the top of the two shoulder straps can be detached and hooked into the multiple hanging holes, the hooking position of the two upper hanging buckles can be adjusted according to the user's different shoulder width, thereby improving the adaptability and comfort of the user's wear.

[0009] Additionally, an adjustable backpack is provided, comprising: a bag body, shoulder straps, a top hook, and a bottom hook. The upper back of the bag body is sewn with an upper hanging strap along its width direction. The upper hanging strap has multiple hanging holes spaced apart along its length direction. The lower back of the bag body has two lower hanging straps symmetrically sewn on. The two lower hanging straps form hanging holes with the adjacent back of the bag body. There are two shoulder straps. There are two upper hooks, which are sewn onto the top of the two shoulder straps respectively. The two upper hooks are detachable and hooked onto the multiple upper hanging holes to increase or decrease the distance between the tops of the two shoulder straps. There are two lower hooks, which are sewn onto the bottom of the two shoulder straps respectively. The two lower hooks are detachable and hooked onto the two lower hanging holes respectively.

[0010] The beneficial effects of this utility model are: it subverts the traditional connection method of fixing and sewing the shoulder straps of a backpack. First, an upper hanging strap is set on the upper part of the back of the bag body, and then two upper hanging buckles are sewn to the top of the two shoulder straps respectively. Since the upper hanging strap has multiple hanging holes spaced along its length, and since the two upper hanging buckles sewn to the top of the two shoulder straps can be detached and hooked into the multiple hanging holes, the hooking position of the two upper hanging buckles can be adjusted according to the user's different shoulder width, thereby improving the adaptability and comfort of the user's wear.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the two upper hooks are detachably hooked onto the two upper hook holes from bottom to top; the two lower hooks are detachably hooked onto the two lower hook holes from bottom to top.

[0013] The further beneficial effect of adopting the above method is that by hooking the two upper hooks onto the two upper hook holes from bottom to top, and by hooking the two lower hooks onto the two lower hook holes from bottom to top, the force direction of the shoulder straps after the backpack is worn can be aligned with the direction of force on the backpack, thereby improving the stability and sturdiness of the backpack when worn.

[0014] Furthermore, the two upper hooks and the two lower hooks have the same structure and each includes a hand-held plate, an L-shaped connecting plate, and a suspension block. The hand-held plate is provided with a connecting hole for connecting to the end of the shoulder strap. The L-shaped connecting plate is fixed to the hand-held plate and defines a suspension gap between the hand-held plate and the L-shaped connecting plate. The suspension block is located within the suspension gap and is fixed to the L-shaped connecting plate.

[0015] The further beneficial effects of adopting the above are: the innovative design of the new upper and lower hook structures can reduce the weight of the upper and lower hooks and improve the ease of assembly and disassembly of the upper and lower hooks.

[0016] Furthermore, the cross-section of the suspension block is a right-angled trapezoid.

[0017] Furthermore, the handheld plate has handheld slots on both opposite sides.

[0018] The further beneficial effect of adopting the above is that by setting hand slots on opposite sides of the handheld plate, the operability of the hand to grasp the upper and lower hooks can be improved.

[0019] Furthermore, the handheld plate, the L-shaped connecting plate, and the suspension block are all made of elastic plastic material.

[0020] The further beneficial effects of adopting the above are: the hand-held plate, the L-shaped connecting plate and the hanging block are all made of elastic plastic material, which can improve the convenience of hooking the upper and lower hooks when the L-shaped connecting plate is elastically deformed.
