Description

Technical Field

[0001] This application relates to a backpack, and more particularly to a backpack with adjustable shoulder straps. Background Technology

[0002] Currently, backpacks on the market generally include a backpack body, shoulder straps, and a waist support. The backpack body is used to carry items, while the shoulder straps are used to maintain the balance of the backpack body, prevent the backpack body from slipping, and transfer a small amount of weight to the shoulders. The shoulder straps are designed according to ergonomics, which can effectively distribute part of the load (that is, the weight of the backpack body) evenly between the shoulders.

[0003] Most existing backpacks have fixed shoulder strap widths and heights, making it impossible to adjust the width according to the shoulder width and height of different people. In addition, most lumbar supports are separate structures, which cannot support the waist and affect comfort. Utility Model Content

[0043] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0044] Figures 1-2 This diagram illustrates the structure of a backpack with an adjustable shoulder strap 300 according to an embodiment of this application. Figures 1-2 As shown, the backpack may include:

[0045] Ontology 100;

[0046] The lumbar support 200 is set on the main body 100. When carrying a backpack, the lumbar support 200 corresponds to the waist of the human body.

[0047] The shoulder strap 300 has two detachable ends that are respectively attached to the main body 100 and the waist support 200.

[0048] In this embodiment, by detachably mounting the shoulder straps 300 onto the main body 100, the height and width between the two shoulder straps 300 can be adjusted. This allows for adjustment of the width between the two shoulder straps 300 according to the shoulder width and height of different individuals, thereby improving the comfort of carrying the load. The lumbar support 200 protects the waist and sides of the body, and the lumbar support 200 is filled with sponge to support the waist.

[0049] like Figures 1-2 As shown, in one embodiment, it further includes:

[0050] Hook and loop fastener 110 is provided on the main body 100;

[0051] The hook and loop fastener 310 is located at the end of the shoulder strap 300 away from the waist support 200. When the shoulder strap 300 is installed on the body 100, the hook and loop fastener 110 is bonded to the hook and loop fastener 310.

[0052] In this embodiment, the hook and loop side 110 and the hook and loop side 310 are bonded together, which facilitates the fixing and removal of the shoulder strap 300 so that the shoulder strap 300 can provide a certain support for the back.

[0053] Furthermore, the loop side 110 is provided on the main body 100 to prevent the hook side 310 from scratching the user's skin when the user carries the bag.

[0054] Specifically, the part where the shoulder strap 300 and the Velcro surface 110 are attached is provided with a rigid plate. The rigid plate facilitates the attachment of the shoulder strap 300 to the body 100 and also facilitates the support of the shoulder strap 300 to the back of the human body.

[0055] The shoulder strap 300 is filled with a sponge pad, with the hard plate facing the Velcro side 110 and the sponge pad facing the body.

[0056] like Figures 1-2 As shown, in one embodiment, it further includes:

[0057] Two first straps 210 are set on the waist support 200;

[0058] Two D-ring buckles are set on the corresponding shoulder strap 300 near the waist support 200. The D-ring buckles are connected to the corresponding first strap 210 so that the shoulder strap 300 is installed on the waist support 200.

[0059] In this embodiment, one end of the shoulder strap 300 is attached to the waist support 200 via the first strap 210 and the D-ring buckle. When the shoulder strap 300 is carried on the body, the waist support 200 bends under the tension of the shoulder strap 300 to protect the side waist.

[0060] like Figures 1-2 As shown, in one embodiment, it further includes:

[0061] Two second straps 220 are respectively set at both ends of the waist support 200;

[0062] Sub-clamp 230;

[0063] The female buckle 240 and the female buckle 230 are respectively set on the two second straps 220. The two second straps 220 are fixed to the user's waist by the female buckle 240 and the female buckle 230.

[0064] In this embodiment, by setting the second strap 220, when the user is carrying the bag, the sub-buckle 230 and the female buckle 240 are fastened together, so that the second strap 220 tightly binds the waist support 200 to the user's waist, supports the user's waist, and at the same time provides a certain protection for the side waist.

[0065] like Figures 1-2 As shown, in one embodiment,

[0066] The width of the lumbar support 200 is greater than the width of the main body 100. The two ends of the lumbar support 200 have protrusions 250. When the male buckle 230 and the female buckle 240 fix the second strap 220 to the user's waist, the protrusions 250 of the lumbar support 200 fit against the user's side waist.

[0067] In this embodiment, when the second strap 220 is fixed by the sub-buckle 230 and the female buckle 240, the protrusion 250 bends to protect the side waist of the human body.

[0068] Specifically, when the lumbar support 200 is in a flat state, the height of the protruding part 250 of the lumbar support 200 is higher than the height of the middle part, thereby enabling the lumbar support 200 to protect the side waist and increase the comfort of the waist.

[0069] like Figures 1-2 As shown, in one embodiment,

[0070] The protrusion 250 of the lumbar support 200 has a storage bag for storing the second strap 220.

[0071] In this embodiment, when the backpack is not in use or the waist support is not needed, the second strap 220 can be stored in the storage bag to save space.

[0072] like Figures 1-2 As shown, in one embodiment, it further includes:

[0073] Card holder 400 is disposed on the main body 100 and has several card slots 401;

[0074] The card block 410 is set on the shoulder strap 300 and is adapted to the card slot 401. When the shoulder strap 300 is set on the body 100, the card block 410 is located in one of the card slots 401.

[0075] In this embodiment, the width of the slot 401 is greater than the width of the block 410. By engaging the block 410 with the slots 401 at different heights, the height of the shoulder strap 300 can be easily adjusted.

[0076] By engaging the clip 410 at different positions in the clip slot 401, the distance between the two shoulder straps 300 can be adjusted, thereby changing the width of the two shoulder straps 300.

[0077] In one implementation,

[0078] The card block 410 has a protrusion 411, and the card holder 400 has an opening that matches the card slot 401. The protrusion 411 enters the card block 410 through the opening.

[0079] In this embodiment, the card slot 401 has an opening, and the protrusion 411 enters the card slot 401 through a snap fastener;

[0080] The slot 401 also has a slot that matches the protrusion 411. When the protrusion 411 enters the slot 401, the card block 410 is pushed upward so that the protrusion 411 enters the slot, thereby fixing the card block 410 on the card holder 400, thereby changing the height and width of the two shoulder straps 300.

[0081] Specifically, the cross-section of the protrusion 411 is T-shaped, which prevents the protrusion 411 from falling out of the slot 401 after it enters the slot 401 through the opening.
