Description

Technical Field

[0001] The utility model relates to a load-reducing backpack with an organ elastic belt. Background Art

[0002] With the increasing demand for backpacks in daily life and work, backpacks have become a common carrying tool, widely used by students, commuters, travelers, and outdoor enthusiasts. Backpack design increasingly emphasizes comfort, load-bearing capacity, and functionality to meet the needs of different scenarios. However, existing backpack designs, particularly in the structure and material selection of backpack straps, still face some technical challenges, particularly regarding how to reduce carrying pressure, improve comfort, and enhance the backpack's load-bearing capacity.

[0003] In the existing technology, backpack straps are mostly designed with flat elastic webbing or foam-filled shoulder straps to provide a certain degree of cushioning and comfort. However, these traditional designs have some shortcomings, which are specifically manifested in the following aspects:

[0004] Traditional flat elastic webbing is often designed with a fixed length, which doesn't allow for flexible expansion and contraction to accommodate varying loads. While some backpack straps incorporate built-in elastic material, these lack the range and elasticity to effectively distribute the pressure and shock to the shoulders when carrying heavy loads. This lack of elasticity causes the backpack to rely excessively on fixed components to support the load, leading to discomfort and fatigue in the shoulders and back.

[0005] When carrying heavy loads, especially while walking or exercising, a backpack is subject to vibration and shaking. Traditional backpack straps lack sufficient cushioning to effectively reduce the transmission of shock, which can easily cause repeated impacts on the shoulders and back, increasing the burden and discomfort.

[0006] The elasticity and stretchability of traditional backpack straps are relatively limited, making it difficult to adjust the comfort according to the body shape and carrying method of different users. This causes some users to feel uncomfortable during use and is unable to fully utilize the backpack's load-reducing function.

[0007] Over time, traditional flat elastic webbing and foam shoulder straps are prone to problems such as elasticity attenuation, material aging, and deformation due to long-term stretching and compression, affecting the long-term performance and comfort of the backpack. Utility Model Content

[0008] In response to the deficiencies in the existing technology, the present invention provides an elastic stretch capability based on the accordion principle, which effectively solves the above-mentioned problems in the existing technology and provides users with a more comfortable, stable and durable backpack experience with a load-reducing backpack with an accordion elastic band.

[0009] The technical solution adopted by the utility model to solve its technical problems is:

[0010] A load-reducing backpack with an accordion elastic belt includes a bag body and a backpack strap arranged on the bag body. The backpack strap includes a pleated elastic webbing and a shoulder strap. The pleated elastic webbing is composed of an inner woven elastic rubber rope that can jointly provide elastic and retractable functions and an external pleated structure. The external pleated structure is composed of more than one pleated layer sewn together. The inner woven elastic rubber rope is provided with more than one section and passes through the pleated layer along the extension direction of the pleated layer.

[0011] Preferably, one end of the pleated elastic webbing is connected to the bag body, and the other end is connected to the shoulder strap.

[0012] Preferably, the other end of the shoulder strap is connected to the bag body.

[0013] Preferably, the pleated elastic webbing is connected to the top of the bag body, and the shoulder strap is connected to the bottom of the bag body.

[0014] Preferably, the maximum stretching length of the pleated layer is less than or equal to the maximum stretching length of the inner elastic cord.

[0015] Preferably, the inner woven elastic rubber rope is made of a high-elastic fiber rubber rope.

[0016] Preferably, the inner woven elastic cords are arranged in parallel, and each pleated elastic webbing contains at least two inner woven elastic cords.

[0017] The beneficial effects of the utility model are:

[0018] Daily backpack use, especially when carrying heavy objects, often places significant pressure on the shoulders and back. This pressure is exacerbated when the backpack straps are tight or subject to vibration. Traditional flat elastic webbing lacks sufficient elasticity and cushioning, which can easily cause shoulder discomfort and fatigue. By designing a pleated elastic webbing, the present invention effectively disperses pressure and cushions shock when a heavy object sags, using the expansion and contraction of the pleated layer and the elasticity of the inner elastic cord. This reduces the burden on the shoulders and back, increasing backpack comfort.

[0019] Traditional backpack straps often use flat elastic webbing, which has limited elasticity and lacks sufficient room for expansion, making it difficult to reduce the pressure of carrying heavy loads. This invention uses an accordion-like pleated structure to achieve greater elasticity, allowing the backpack strap to better adapt to different load conditions and enhance the backpack's adaptability and comfort.

[0020] Because the pleated elastic webbing of the present invention automatically expands and contracts according to the load, it not only effectively reduces the load-bearing pressure but also ensures good stability under varying load conditions, avoiding discomfort or instability caused by an unbalanced load. This is crucial for the stability of the backpack during actual use, especially when carrying heavy objects.

[0021] Traditional flat elastic webbing is prone to aging, deformation, or loss of elasticity over long-term use due to poor stretchability and durability. The present invention's pleated elastic webbing, through the combined effect of an inner woven elastic cord and an external pleated structure, improves the durability and elastic recovery of backpack straps, extending the lifespan of the backpack. The pleated elastic webbing provides greater flexibility, allowing the backpack to adapt to different body shapes and user needs, thereby enhancing the backpack's comfort and versatility in various usage scenarios.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0028] See Figure 1-3 As shown, a load-reducing backpack with an accordion elastic band includes a bag body 1 and a backpack strap 2 mounted on the bag body 1. This design utilizes a backpack structure with an accordion elastic band. The design of the backpack strap 2 breaks away from traditional flat elastic bands and can provide a more effective load-reducing effect. The innovative structure of the backpack strap 2 can effectively reduce the pressure and discomfort on the shoulders when carrying items. The backpack strap 2 includes a pleated elastic webbing 3 and a shoulder strap 4. The pleated elastic webbing 3 is composed of an inner woven elastic cord 5 and an outer pleated structure 6 that together provide elasticity and flexibility. By combining the dual functions of the elastic cord 5 and the pleated structure 6, this design not only provides sufficient elasticity and flexibility, but also dynamically adjusts the carrying pressure according to the load conditions. The combined effect of the elasticity of the elastic cord 5 and the pleated structure 6 can better disperse pressure and improve user comfort.

[0029] The external pleated structure 6 is composed of one or more interlocking pleated layers. This multi-layer design helps improve the stretchability and elasticity of the backpack strap 2, while also better adapting to changes in the user's body shape and load. The interlocking pleated structure 6 ensures that the backpack strap 2 maintains its elasticity and stability under various usage conditions. At least one internal woven elastic cord 5 is provided, extending through the pleated layer along its extension direction. This design increases the elasticity adjustment capability of the backpack strap 2. The number and arrangement of the internal woven elastic cords 5 allow for automatic expansion and contraction based on load changes, providing improved shock absorption and pressure-bearing properties, while reducing deformation and insufficient elasticity that can occur with conventional backpack straps 2.

[0030] One end of the pleated elastic webbing 3 is connected to the bag body 1, and the other end is connected to the shoulder strap 4. The other end of the shoulder strap 4 is connected to the bag body 1. The pleated elastic webbing 3 is connected at the top of the bag body 1, and the shoulder strap 4 is connected at the bottom of the bag body 1. The structure of the backpack strap 2 is ergonomically designed. The connection position of the backpack strap 2 helps to evenly distribute the weight of the backpack 1, reducing pressure on the shoulders and spine. The pleated elastic webbing 3 is connected to the bag body 1 at the top, effectively bearing the weight of the bag 1 while distributing the load to the shoulder strap 4, improving comfort.

[0031] The maximum stretch length of the pleated layer is less than or equal to the maximum stretch length of the inner elastic cord 5. This design ensures that the backpack strap 2 does not overstretch, thus preventing deformation and failure of the backpack strap 2 during prolonged use. The inner elastic cord 5 has greater stretchability than the outer pleated layer, allowing for better adjustment of the backpack strap 2's expansion and contraction, preventing material fatigue caused by excessive stretching.

[0032] The inner woven elastic cord 5 is made of a high-elastic fiber elastic cord. Using this material enhances the elasticity and durability of the backpack strap 2, ensuring its resilience and stability after prolonged use. This material also exhibits excellent wear resistance and tensile strength, effectively extending the life of the backpack strap 2.

[0033] The inner woven elastic cords 5 are arranged in parallel, with each pleated elastic webbing 3 containing at least two inner woven elastic cords 5. This parallel arrangement ensures a more uniform elastic effect across each pleated elastic webbing 3, preventing uneven stretching of a single elastic cord 5 and enhancing the overall stability and load-bearing capacity of the backpack strap 2. This parallel arrangement also provides improved tensile strength, preventing overall structural failure of the backpack strap 2 due to breakage of a single elastic cord 5.

[0034] Through the above technical design, the backpack strap 2 can provide better load-reducing effect and comfort, and can maintain efficient elastic adjustment and stability under different loads and usage environments, meeting the needs of different user groups.

[0035] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
