Description

Technical Field

[0001] This utility model relates to the field of backpack technology, specifically a backpack with a novel cushioned shoulder strap. Background Technology

[0002] Backpacks are commonly used tools for carrying items in daily travel, work, and outdoor scenarios. Their structural design directly affects their ease of use and comfort, making them an indispensable piece of equipment in people's lives.

[0003] Currently, backpacks on the market typically have shoulder straps on the sides or top to facilitate carrying. Users simply drape the straps over their shoulders to carry the backpack. A search reveals a backpack with pressure-reducing shoulder straps (publication number CN215532354U). To improve shoulder comfort, existing shoulder straps are often made of thick fabric, with some products adding a thicker layer inside the fabric or filling it with flexible materials like sponge to enhance cushioning. However, the cushioning performance of these traditional shoulder strap structures relies primarily on the softness of the material itself, resulting in a single cushioning layer. When users carry the backpack for extended periods or when the backpack is loaded with heavy objects, increasing the stress on the shoulders, the cushioning effect of the shoulder straps becomes poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a backpack with novel cushioning shoulder straps, solving the technical problem of poor cushioning effect of traditional backpack shoulder straps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a backpack with a novel cushioned shoulder strap, comprising a backpack body, a shoulder strap connected to the backpack body, a cushioning strap installed on the shoulder strap, a hollow filling cavity inside the cushioning strap, and a protrusion on the outer surface of the cushioning strap. When the backpack body is in the carrying state, the cushioning strap on the shoulder strap plays a cushioning role with the human shoulder.

[0006] Furthermore, the buffer band is foldable, with a folded portion in the middle. The portion of the buffer band above the folded portion is a connecting portion, which is fixedly connected to the shoulder strap. The portion of the buffer band below the folded portion is a free portion. The buffer band can be folded at the folded portion position, with the free portion folded inward and upward. The free portion overlaps with the connecting portion to form a double-layer structure, thereby increasing the thickness of the buffer band and improving its cushioning capacity.

[0007] Furthermore, the free portion of the cushioning band is connected to a connecting band, and a first connecting member is installed on the connecting band; the shoulder strap is correspondingly provided with a second connecting member adapted to the first connecting member, and the second connecting members are respectively located at the top and bottom positions of the shoulder strap; when the cushioning band is in the unfolded state, the first connecting member on the connecting band can connect with the second connecting member at the bottom position of the shoulder strap; when the cushioning band is in the folded state, the first connecting member on the connecting band can connect with the second connecting member at the top position of the shoulder strap.

[0008] Furthermore, the first connector and the second connector are mating snaps, Velcro, or zippers.

[0009] Furthermore, the bottom of the shoulder strap is provided with a through groove, so that when the cushioning belt is in the unfolded state, the free part of the cushioning belt can be installed in the through groove.

[0010] Furthermore, a flap is installed on the back of the backpack body, and one side of the flap is connected to the backpack body; when the backpack body is in the normal carrying state, the shoulder strap is located outside the flap; when the shoulder strap needs to be stored, the shoulder strap is placed between the flap and the back of the backpack body, and the flap is used to cover the shoulder strap.

[0011] Furthermore, the side of the baffle connected to the backpack body is provided with a mounting part, which is fixedly connected to the back of the backpack body, and the mounting part and the baffle are foldable to realize the folding of the baffle.

[0012] Furthermore, a connecting strip is provided on the back of the backpack body, on the side of the baffle away from the mounting part. The inner side of the connecting strip forms a slot with the back of the backpack body for the side of the baffle to be inserted. When the baffle is inserted into the slot, the side of the baffle is fixed.

[0013] Furthermore, a handle is installed on the top of the backpack body.

[0014] Compared with the prior art, this utility model provides a backpack with a novel cushioned shoulder strap, which has the following beneficial effects:

[0015] This backpack features a novel type of cushioned shoulder strap. By adding cushioning straps to the shoulder straps, which directly contact the user's shoulders, it can directly cushion the force on the shoulders when carried. At the same time, the hollow filling cavity inside the cushioning strap can be filled with air or flexible materials. Combined with the shoulder straps being made of elastic materials such as rubber or soft plastic, the double cushioning structure, through the elasticity of the materials themselves and the filling inside the cavity, significantly improves the cushioning effect compared to traditional shoulder straps that rely solely on thick cloth or a single sponge. Even when carrying heavy loads for extended periods, it can significantly reduce discomfort such as shoulder muscle soreness and marks.

[0016] The protrusions on the outer wall of the cushioning strap provide slight support and anti-slip effect when the cushioning strap contacts the shoulder, preventing the shoulder strap from slipping due to force during carrying and reducing the fit. The protrusions also disperse local pressure, reducing direct large-area pressure between the cushioning strap and the shoulder, further improving the comfort of long-term wear.

[0027] 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.

[0028] Please see Figure 1-2 This utility model discloses a backpack with a novel cushioned shoulder strap, comprising a backpack body 1 and shoulder straps 2. The shoulder straps 2 are fixedly connected to the sides or top of the backpack body 1, allowing the user to drape them over their shoulders for carrying the backpack body 1. The length of the shoulder straps 2 is adjustable, and the length of the shoulder straps 2 can be adjusted by clips on the shoulder straps 2 to improve their adaptability. A handle 17 is installed at the top of the backpack body 1. The handle 17 is made of a wear-resistant and resilient material (such as nylon webbing, reinforced canvas, etc.). When the user does not need to carry the backpack body 1, they can directly hold the handle 17 and lift the backpack body 1 by the handle 17.

[0029] like Figure 3-4 As shown in Figure 6, to improve shoulder comfort and enhance cushioning during carrying, a cushioning band 3 is also installed on the shoulder strap 2. This cushioning band 3 directly contacts the shoulder when the backpack is being carried, forming a cushioning layer between the shoulder strap 2 and the shoulder, reducing the direct pressure of the shoulder strap 2 on the shoulder. The specific structure of the cushioning band 3 is as follows: it has a hollow filling cavity 5 inside, which can be filled with flexible filling materials such as air, sponge particles, and down. Meanwhile, the shoulder strap 2 uses a self-elastic cushioning band 3 material such as rubber or soft plastic. The combination of the material's elasticity and the double cushioning structure of the internal cavity further enhances the cushioning performance. Several protrusions 4 are also provided on the outer surface of the cushioning band 3. These protrusions 4 not only increase the friction between the cushioning band 3 and the shoulder, preventing the shoulder strap 2 from slipping during carrying, but also distribute local pressure, reducing the large-area pressure of the cushioning band 3 against the shoulder, making long-term wear more comfortable.

[0030] In actual use, when the user places the shoulder strap 2 on their shoulder and is in a normal carrying position, the cushioning band 3 on the shoulder strap 2 will rely on its own material characteristics and work with the flexible support of the internal filling cavity 5 to directly cushion between the shoulder and the shoulder strap 2, effectively relieving the shoulder burden caused by the weight of the backpack, especially suitable for carrying for a long time or when the backpack is loaded with a lot of items.

[0031] To further improve the cushioning effect of the shoulder strap 2, the cushioning band 3 is designed to be foldable. A fold 6 is provided in the middle of the cushioning band 3, which divides the cushioning band 3 into upper and lower parts: the part of the cushioning band 3 above the fold 6 is the connecting part 7, which is fixedly connected to the shoulder strap 2 (it can be connected by sewing) to ensure the overall installation stability of the cushioning band 3 on the shoulder strap 2; the part of the cushioning band 3 below the fold 6 is the free part 8, which is not fixed to the shoulder strap 2 and can move flexibly.

[0032] When enhanced cushioning is needed, the cushioning band 3 can be folded: Fold the free portion 8 of the cushioning band 3 towards the inside of the cushioning band 3 at the folding part 6, and fold it upwards, so that the free portion 8 completely overlaps with the connecting part 7. At this time, the cushioning band 3 changes from a single-layer structure to a double-layer structure, increasing its overall thickness and significantly improving the cushioning effect on the shoulders. This is suitable for carrying heavy items in the backpack or carrying the backpack body 1 for extended periods. If the backpack body 1 is lightly loaded and no additional cushioning is needed, the free portion 8 can be unfolded, keeping the cushioning band 3 in a single-layer state.

[0033] like Figure 4 and 8 As shown, to ensure stable fixation of the buffer band 3 in both unfolded and folded states, at least one connecting strap 9 is connected to the bottom of the free portion 8 of the buffer band 3. The connecting strap 9 can also be located on both sides to limit the movement of the buffer band 3 to the sides. A first connecting member 10 is installed on the connecting strap 9. Correspondingly, a second connecting member 11 is provided on the shoulder strap 2 to match the first connecting member 10. The second connecting member 11 is installed in two positions, fixedly located at the top and bottom positions of the shoulder strap 2, respectively.

[0034] When the cushioning strap 3 is unfolded, the free part 8 hangs down naturally. At this time, the first connector 10 on the connecting strap 9 can connect and fix with the second connector 11 at the bottom of the shoulder strap 2, thus securing the free part 8 and preventing it from shaking during carrying. When the cushioning strap 3 is folded to form a double-layer structure, the free part 8 folds upward and overlaps with the connecting part 7. At this time, the connecting strap 9 moves upward synchronously with the free part 8, and the first connector 10 connects and fixes with the second connector 11 at the top of the shoulder strap 2, thereby securing the cushioning strap 3 and maintaining its double-layer structure. Alternatively, the connecting strap 9 can be used on both sides to connect to the shoulder strap 2 to prevent the cushioning strap 3 from moving to the sides.

[0035] The first connector 10 and the second connector 11 adopt a mutually cooperating connection structure, specifically a snap fastener, Velcro or zipper or other connection structure, to ensure that the first connector 10 and the second connector 1 can be stably connected to fix the buffer strip 3.

[0036] If snap fasteners are used, the first connector 10 is the male (or female) snap fastener, and the second connector 11 is the female (or male) snap fastener. Pressing the snap fastener completes the fastening and fixing. Disassembly is easy and quick, requiring only a slight pry. If Velcro is used, the first connector 10 is the hook side (or loop side) of the Velcro, and the second connector 11 is the loop side (or hook side) of the Velcro. Fastening is achieved by attaching the Velcro. If a zipper is used, the first connector 10 is the zipper strap on one side, and the second connector 11 includes the zipper head and the zipper strap on the other side. Pulling the zipper head completes the closing and fixing, providing better stability and effectively preventing the free part 8 of the buffer strip 3 from accidentally coming loose during vigorous activity.

[0037] like Figure 1 and 7 As shown, a through groove 12 is provided at the bottom of the shoulder strap 2. The shape and size of the through groove 12 are adapted to the shape of the free part 8 of the cushioning band 3. When the cushioning band 3 is in the unfolded state, the free part 8 hangs down naturally and can be embedded in the through groove 12 to prevent the free part 8 of the cushioning band 3 from rubbing against the clothing due to shaking when it is in the unfolded state.

[0038] Traditional backpacks have exposed shoulder straps, which can cause safety hazards and aesthetic problems. The shoulder straps 2 of traditional backpacks are mostly directly exposed on the back side of the backpack body 1. When the user lifts the backpack body 1 through the handle 17, the shoulder straps 2 will naturally droop down due to their length. This not only affects the overall neatness and aesthetics of the backpack, but the excessively long drooping shoulder straps 2 may also snag on surrounding objects or the user's feet during movement, posing a safety hazard of tripping the user.

[0039] like Figure 1 and 3 As shown, this patent involves installing a baffle 13 on the back side of the backpack body 1. One side of the baffle 13 is fixedly connected to the back side of the backpack body 1, while the other side can be folded freely. When the backpack body 1 is in a normal carrying position, the baffle 13 is in a position that fits against the back side of the backpack body 1. At this time, the shoulder strap 2 is located outside the baffle 13 and is not covered by the baffle 13, allowing the user to directly drape the shoulder strap 2 over their shoulder for carrying. When the user does not need to carry the backpack body 1 (such as when carrying the backpack body 1 by hand) and needs to store the shoulder strap 2, they can first straighten the shoulder strap 2, then fold the baffle 13 to place the entire shoulder strap 2 in the gap between the baffle 13 and the back of the backpack body 1. Then, the baffle 13 is flipped towards the back side of the backpack body 1 to cover the inner shoulder strap 2.

[0040] The specific connection structure between the baffle 13 and the backpack body 1 is as follows: the side where the baffle 13 is connected to the backpack body 1 is provided with an installation part 14. The installation part 14 is fixed to the backpack by means of sewing, hot pressing, or riveting to form a firm connection with the back of the backpack body 1, ensuring that the baffle 13 will not fall off or shift during use.

[0041] Meanwhile, the mounting part 14 and the baffle 13 are designed to be foldable, which can be achieved in two ways: one is to use flexible fabric to sew the mounting part 14 and the baffle 13 together, and use the flexibility of the fabric itself to form a natural folding area; the other is to set a crease line at the connection between the mounting part 14 and the baffle 13.

[0042] The baffle 13 can be made of a fabric with a certain degree of stiffness, such as canvas or nylon. Alternatively, a soft fabric can be used on the surface of the baffle 13, with thickened padding such as sponge or rubber sheets inside. When the user carries the backpack body 1 on their back, the baffle 13 will naturally conform to the back. The baffle 13 also increases the contact thickness between the back of the backpack body 1 and the user's back, forming a cushioning layer. The baffle 13 not only serves to shield the user's back but also provides cushioning from the back of the backpack body 1, improving the overall carrying comfort.

[0043] like Figure 5 and 9 As shown, a connecting strip 15 is fixedly provided on the back of the backpack body 1, on the side of the baffle 13 away from the mounting part 14. The connecting strip 15 is made of fabric. The connecting strip 15 is long and narrow, with a gap reserved between the inner side of the connecting strip 15 and the back of the backpack body 1, forming a slot 16 for the side of the baffle 13 to be inserted. The width of the slot 16 is adapted to the thickness of the baffle 13, ensuring that the side of the baffle 13 can be smoothly inserted into the slot 16, thereby fixing the side of the baffle 13. When the baffle 13 is used to cover and store the shoulder strap 2, the insertion of the baffle 13 into the slot 16 can prevent the baffle 13 from flipping due to external force, ensuring that the shoulder strap 2 is always covered by the baffle 13. When the baffle 13 is in the normal carrying position, the insertion of the baffle 13 into the slot 16 can prevent the baffle 13 from flipping or sticking up at will during walking or movement, so that it fits tightly against the back of the backpack body 1, further enhancing the cushioning effect of the baffle 13 on the back.

[0044] In summary, this backpack with a novel cushioning shoulder strap 2 allows the user to simply drape the shoulder strap 2 over their shoulder and carry the backpack body 1 using the shoulder strap 2 when carrying the backpack normally. At this time, the cushioning band 3 on the shoulder strap 2 will naturally contact the shoulder, providing basic cushioning for the shoulder based on its material properties and the support of the internal filling cavity 5, relieving the pressure from the weight of the backpack; at the same time, the side of the baffle 13 away from the mounting part 14 is inserted into the slot 16 on the back of the backpack, closely fitting the back of the backpack body 1, improving the back cushioning effect.

[0045] When carrying the backpack for an extended period of time, or when the backpack body 1 is overloaded and the shoulder cushioning needs to be enhanced, the cushioning strap 3 can be folded: fold the free part 8 below the fold 6 in the middle of the cushioning strap 3 towards the inside of the cushioning strap 3 and upwards until the free part 8 completely overlaps with the connecting part 7 above, so that the cushioning strap 3 forms a double-layer structure; then connect and fix the first connector 10 on the connecting strap 9 to the second connector 11 at the top of the shoulder strap 2 to fix the double-layer structure. By increasing the thickness of the cushioning strap 3, the cushioning effect is further enhanced, reducing shoulder discomfort.

[0046] When the user is not carrying the backpack and chooses to move by hand using the main body 1 (via the top handle 17), the side of the cover 13 away from the mounting part 14 can be pulled out of the slot 16. Then, the shoulder strap 2 can be straightened and placed against the back of the main body 1. Next, the cover 13 can be folded over to the outside of the shoulder strap 2, completely covering it. The side of the cover 13 away from the mounting part 14 can then be reinserted into the slot 16, securing the side of the cover 13. At this point, the shoulder strap 2 is stably positioned between the cover 13 and the back of the main body 1, preventing it from sagging or swaying. When the user carries the backpack, the shoulder strap 2 is less likely to fall out of the gap or cause a tripping hazard due to drooping. Furthermore, the drooping shoulder strap 2 is not visible from the outside of the main body 1, improving aesthetics.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
