BACKPACK WITH ADJUSTABLE SHOULDER WIDTH

Description

TECHNICAL FIELD

The disclosure relates to the field of backpacks, specifically a backpack with adjustable shoulder width.

BACKGROUND ART

Backpacks are widely used, from student schoolbags to athlete bags, and they can be seen everywhere wherever there are people. The advantage of backpacks is that the shoulders bear the weight, and compared with other types of bags, they basically do not affect the movements of the limbs, so they are very popular.

Conventional shoulder backpacks, such as Chinese patent for invention with patent No. CN103653695A with the name of a backpack, and Chinese patent for invention with patent No. CN116548721A with the name of a backpack, use two adjustable-length straps fixedly sewn to the back of the backpack body. Although the two straps can be securely sewn to the back of the backpack body, different people have different physiques, and the different physiques also have different shoulder widths. When the width between the two shoulder straps of a traditional backpack is a fixed value, it is easy to enhance the unsuitability of individual users for wearing, resulting in a rapid decline in sales of backpacks.

Therefore, it is an urgent problem to be solved by those skilled in the art to design a backpack with a simple structure, low cost, easy wearing, and adjustable shoulder width.

SUMMARY

The present disclosure provides a backpack with adjustable shoulder width, addressing the technical issue of increased discomfort for users due to the inability to adjust the shoulder width in existing backpacks.

The technical solution provided by the present disclosure for solving the above technical problem is as follows: a backpack with adjustable shoulder width includes a bag body, straps and upper hanging buckles.

The upper back part of the bag body is sewn with an upper hanging band along its width direction, and the upper hanging band is provided with multiple upper hanging holes spaced apart along its length direction; the straps are two in number; the bottom ends of the two straps are symmetrically sewn at intervals on the lower back part of the bag body; the upper hanging buckles are two in number and each is sewn to the top end of one of the straps, the two upper hanging buckles are detachably hooked onto the multiple upper hanging holes to expand or reduce the distance between the top ends of the two straps.

The beneficial effect of the present disclosure is as follow: it overturns the traditional method of fixed sewing for the straps of backpacks, by first setting an upper hanging band on the upper back part of the bag body, and then sewing the two upper hanging buckles at the top ends of the two straps. Since there are multiple upper hanging holes spaced along the length of the upper hanging band, and since the two upper hanging buckles sewn at the top ends of the two straps can be detachably hooked onto the multiple upper hanging holes, the hooking position of the two upper hanging buckles can be adjusted according to the different shoulder widths of users, improving the adaptability and comfort of wearing the backpack.

Additionally, the present disclosure provides a backpack with adjustable shoulder width, including a bag body, straps, upper hanging buckles and lower hanging buckles.

The upper back part of the bag body is sewn with an upper hanging band along its width direction, and the upper hanging band is provided with multiple upper hanging holes spaced apart along its length direction; the lower back part of the bag body is symmetrically sewn with two lower hanging bands, and the two lower hanging bands respectively form lower hanging holes with the adjacent back of the bag body; the straps are two in number; the upper hanging buckles are two in number and each is sewn to the top end of one of the straps, the two upper hanging buckles are detachably hooked onto the multiple the upper hanging holes to expand or reduce the distance between the top ends of the two straps; the lower hanging buckles are two in number and each is sewn to a bottom end of one of the straps, the two lower hanging buckles are detachably hooked onto two the lower hanging holes.

The beneficial effect of the present disclosure is as follow: it overturns the traditional method of fixed sewing for the straps of backpacks, by first setting an upper hanging band on the upper back part of the bag body, and then sewing the two upper hanging buckles at the top ends of the two straps. Since there are multiple upper hanging holes spaced along the length of the upper hanging band, and since the two upper hanging buckles sewn at the top ends of the two straps can be detachably hooked onto the multiple upper hanging holes, the hooking position of the two upper hanging buckles can be adjusted according to the different shoulder widths of users, improving the adaptability and comfort of wearing the backpack.

On the basis of the above technical solutions, the present disclosure can also be improved as follows.

Further, the two upper hanging buckles are respectively detachably hooked onto two of the upper hanging holes from bottom to top; the two lower hanging buckles are respectively detachably hooked onto two of the lower hanging holes from bottom to top.

The beneficial effect of adopting the further improvement is as follows: by hooking the two upper hanging buckles onto two upper hanging holes from bottom to top, and simultaneously hooking the two lower hanging buckles onto two lower hanging holes from bottom to top, it aligns with the direction of force on the shoulder straps after wearing the backpack, enhancing the firmness and stability of wearing the backpack.

Further, two the upper hanging buckles and two the lower hanging buckles have the same structure and include a handheld plate, an L-shaped connecting plate, and a hanging block, the handheld plate is provided with a connecting hole for connecting to an end of the strap; the L-shaped connecting plate is fixed on the handheld plate and defines a hanging gap between the handheld plate and the L-shaped connecting plate; the hanging block is located within the hanging gap and fixed on the L-shaped connecting plate.

The beneficial effect of adopting this further improvement is as follows: by innovatively designing a new structure for both the upper hanging buckles and lower hanging buckles, the weight of the upper hanging buckles and lower hanging buckles is reduced and the convenience of disassembling and assembling the upper hanging buckles and lower hanging buckles is improved.

Further, the cross section of the hanging block is a right trapezoid.

Further, two opposite sides of the handheld plate are both provided with a holding groove.

The beneficial effect of adopting this further improvement is as follows: by providing handheld grooves on both opposite sides of the handheld plate, it enhances the operability of grasping the upper hanging buckles and lower hanging buckles by hand.

Further, the handheld plate, the L-shaped connecting plate, and the hanging block are all made of elastic plastic material.

The beneficial effect of adopting this further improvement is as follows: by selecting elastic plastic material for the handheld plate, L-shaped connecting plate and hanging block, it facilitates convenient hooking of the upper hanging buckles and lower hanging buckles when the L-shaped connecting plate elastically deforms.
