Description

Technical Field

[0001] The invention relates to the technical field of shoe uppers, and in particular to a suspension bridge type shoe upper. Background Art

[0002] In the field of modern footwear manufacturing, the force-bearing support structure of the upper has always been a key factor in improving the comfort, functionality and durability of shoes. As people's requirements for the wearing experience of various footwear products are increasing, many footwear manufacturers are committed to developing more advanced upper support technologies to meet the needs of consumers in different scenarios. For example, in the field of sports shoes, they need to cope with the complex and changeable force conditions of the feet during high-intensity exercise, and in outdoor shoes, they need to consider the stable support of the feet under rugged road conditions.

[0003] At present, there are many existing technologies for achieving force support of shoe uppers in the domestic and foreign markets, among which the following are relatively similar to the technical solutions of the present patent application:

[0004] 1. Traditional cushion support structure

[0005] Many footwear products have pads inside the upper to provide a certain amount of support. The technical structure is usually made of soft materials with a certain degree of elasticity, such as sponges and foams, which are cut into suitable shapes and attached to the inner layer of the upper, distributed in the main stress-bearing parts such as the soles of the feet and heels. In terms of technology, it is generally fixed to the upper by gluing or simple stitching.

[0006] Although this traditional cushioning support structure can alleviate the impact of the foot on the shoe surface to a certain extent and play a buffering role in actual use, its shortcomings are also obvious. Since the elasticity of the cushioning material is relatively uniform and fixed, it is impossible to accurately adjust the support strength according to the actual force size and direction of each force point under different movement postures of the foot. For example, when running, the force on the outside of the forefoot will suddenly increase at the moment the foot touches the ground, but the cushioning support is difficult to specifically enhance the support here, which may cause local excessive pressure on the foot, affecting the comfort of wearing, and even causing deformation of the shoe surface and accelerated wear in the long run. Moreover, after wearing for a long time or performing complex exercises, the cushioning is easily compacted and loses its original elasticity, which greatly reduces the support effect.

[0007] 2. Rigid support sheet structure

[0008] Some shoes, especially some sports shoes or outdoor shoes that emphasize stability, will incorporate hard support plates in the upper, and common materials include plastic, carbon fiber sheets, etc. From the perspective of technical structure, these hard support plates are generally placed in key parts of the upper, such as the arch of the foot and both sides of the heel, and are connected and fixed to the upper and sole through specific slots or stitching processes, aiming to provide stable and strong support for the upper.

[0009] However, the rigid support sheet structure also has many limitations. On the one hand, although its support strength is strong, it lacks flexibility and cannot dynamically adapt to the changing stress conditions of the foot during different movements. For example, in sports scenes where walking and running alternate, the force points of the foot will quickly shift to different areas of the sole, and the rigid support sheet cannot flexibly change the support position and strength accordingly, which can easily make the wearer feel stiff and uncomfortable in the foot. On the other hand, due to its hard material, if it does not fit tightly enough with the upper or has poor adaptability, it may also cause a local sense of pressure on the foot, and may even cause damage to the upper material during frequent bending, affecting the overall service life of the shoe.

[0010] 3. Local elastic mesh structure

[0011] In recent years, some shoes have also used local elastic mesh as an auxiliary support structure for the upper. Usually, mesh materials with a certain elasticity are used in stress-prone areas of the upper, such as above the toes and around the ankles, and are integrated into the overall structure of the upper through a weaving process. In terms of technology, it is necessary to accurately control the weaving density of the mesh and the distribution of elastic fibers to achieve a certain support function.

[0012] Although this local elastic mesh structure can provide dynamic support to a certain extent based on the stretching and rebounding of the foot movement, the problem is that its force dispersion and support accuracy are still limited. Since the elasticity of the mesh mainly depends on the characteristics of the fiber itself and the weaving structure, it is difficult to transmit and disperse the force highly accurately according to the specific force conditions of different parts of the foot like an ideal precision support structure. And when facing a large external force impact, such as when jumping and landing, the support force it can provide may not be enough to effectively protect the foot and maintain the stability of the upper. The mesh is prone to excessive stretching and deformation, and then it cannot be restored to its original state, affecting the subsequent support effect and the aesthetics of the upper.

[0013] To sum up, although these existing similar existing technologies related to upper force support can play their respective roles to a certain extent, they have failed to solve the key problem of accurate upper force support. It is difficult to simultaneously meet the requirements that the upper can adaptively and accurately support and disperse the force when the force on the foot changes under different motion states. There is still room for further improvement in improving wearing comfort, extending the service life of the upper, and ensuring the overall functionality of the shoe. Summary of the invention

[0014] In view of the above-mentioned problems, the present invention proposes a suspension bridge type shoe upper.

[0015] The technical solution of the present invention is as follows:

[0016] A suspension bridge type vamp includes a vamp, on which a plurality of first suspension cables are arranged. The first suspension cables are elastic suspension cables, both ends of which are fixed to the vamp, and the first suspension cables extend from the front end to the rear end of the vamp or from the middle part to the outer edge of the vamp.

[0017] Preferably, it further comprises a plurality of second suspension cables, wherein the second suspension cables are elastic suspension cables, both ends of the second suspension cables are fixed to the shoe upper, and the second suspension cables are arranged alternately with the first suspension cables.

[0018] Preferably, the first suspension cable and the second suspension cable are woven and connected to each other to form a stable and elastic mesh layout.

[0019] Preferably, the number of the first suspension cables is 3-5, and the intervals between the second suspension cables are 2-3 cm.

[0020] Preferably, both ends of the first suspension cable and the second suspension cable are fixed to the shoe upper via fixing members.

[0021] Preferably, the fixing member comprises sutures, and both ends of the first suspension cable are fixed to the shoe upper by sutures.

[0022] Preferably, the fixing member comprises a supporting fixing member and a connecting member, the supporting fixing member is fixed to the shoe upper, and the end of the first suspension cable is connected to the supporting fixing member through the connecting member.

[0023] Preferably, the supporting fixing member is a columnar member or a block member, the connecting member is a connecting ring, and the supporting fixing member is provided with a connecting hole or a slot that cooperates with the connecting ring.

[0024] Preferably, the supporting fixing member is a metal member or a plastic member, and the connecting ring is a metal buckle, a rope ring or a plastic ring.

[0025] Preferably, the shoe upper is at least one layer, and the first suspension cable and the second suspension cable are located on the upper surface of the shoe upper, or the first suspension cable and the second suspension cable are located in the middle of the shoe upper.

[0026] Beneficial effects of the present invention:

[0027] The technical solution of the shoe upper precise force support constructed based on the principle of suspension bridge in the present invention shows many significant advantages and beneficial effects compared with the existing shoe upper force support related technologies such as traditional liner support structure, hard support sheet structure and local elastic mesh structure, as follows:

[0028] 1. Accurate force adjustment capability

[0029] Unlike the traditional cushion-type support structure that relies on fixed elastic materials for simple buffering, the first and second cables of the present invention are arranged in a criss-cross mesh and are made of high-performance materials with good elastic recovery capabilities. This allows the cables to produce corresponding deformations in real time and accurately according to the actual stress conditions when the foot performs different movements (such as walking, running, jumping, etc.), no matter where the force point is on the shoe surface, and how the magnitude and direction of the force changes, just like the cables of a suspension bridge respond to different loads on the bridge, and adjust the support strength adaptively. For example, during running, when the force on the outside of the forefoot increases at the moment the foot touches the ground, the corresponding cables here will quickly stretch and disperse the force, accurately enhance the support of this part, avoid local excessive pressure, and provide the foot with a highly fitting and just the right support effect, greatly improving the comfort of wearing, and effectively solving the problem that traditional cushion-type supports are difficult to dynamically and accurately adjust.

[0030] 2. High flexibility and adaptability

[0031] Compared with the rigid support sheet structure that lacks flexibility due to its own rigidity, the present invention draws on the flexible strain characteristics of the suspension bridge when bearing dynamic loads, and the first cable, the second cable and the overall support structure can be flexibly adjusted when stressed. In sports scenes where the force points of the feet switch quickly and the force conditions are complex and changeable (such as alternating between walking and running, changing directions, etc.), the cables can smoothly change the force state with the movement of the feet, and quickly adjust the support strength and direction, so that the shoes are always compatible with the movement of the feet, and the wearer will not feel stiff or restricted in the feet. This high degree of flexibility and adaptability ensures the wearer's natural experience during various sports, and makes up for the disadvantage that the rigid support sheet structure cannot adapt dynamically.

[0032] 3. Excellent force dispersion and upper durability

[0033] Compared with the limited dispersion accuracy of the force of the local elastic mesh structure and the insufficient support force under the impact of large external forces, the present invention can evenly disperse the force applied by the foot to the upper to the entire support structure in a more scientific and reasonable manner through the mesh layout of the suspension cables and the synergy with the support fixed points. Just like a suspension bridge evenly disperses the load on the bridge to each supporting part, it effectively reduces the local pressure on the upper and avoids damage such as premature wear and tear of the upper due to uneven local force. Whether it is worn for a long time in daily life or in response to frequent force impacts during high-intensity exercise, the upper can maintain good integrity and support performance, significantly extending the service life of the upper, and fundamentally optimizing the long-term effect of the upper force support.

[0034] 4. Comprehensively improved wearing experience and functionality

[0035] Combining the above advantages, the present invention comprehensively improves the overall wearing experience of footwear products. Not only in terms of comfort, the wearer can feel the precise, flexible, long-lasting and stable upper support, reducing foot fatigue and discomfort; in terms of functionality, it also enables the shoes to better adapt to a variety of sports and daily wear needs. For example, for sports shoes, in high-intensity confrontational sports such as basketball and football, the support structure of the present invention can ensure the stability and safety of the feet in complex movements such as rapid movement, jumping, and sudden stops; for outdoor shoes, when walking on rugged roads, it can also ensure that the force on the feet is reasonable, and improve the overall durability and reliability of the shoes. Compared with various existing upper support technologies, this further expands the advantages of footwear products in different application scenarios and brings consumers better use value.
