Description

Technical Field

[0001] The present invention relates to the technical field of shoe uppers, in particular to a shoe upper and a shoe with a springtail segmented structure. Background Art

[0002] In the field of footwear manufacturing, as people's requirements for wearing comfort and shoe functionality continue to increase, the ability of the upper to better adapt to foot movements and possess dynamic expansion and contraction capabilities has become one of the key research and development directions. The following is an introduction to existing technologies that are relatively similar to the technical solution of this patent application and their shortcomings:

[0003] 1. Technical Structure and Process of Existing Technology

[0004] 1. Elastic material upper technology:

[0005] To achieve a certain degree of stretchability, many footwear products often use textile materials that incorporate elastic fibers (such as spandex) into their uppers. This technology involves blending elastic fibers with conventional polyester, cotton, and other fibers in a specific proportion to create a stretchable fabric. This fabric is then cut and sewn together to create the upper. The process is relatively simple, leveraging the inherent stretch and retraction properties of elastic fibers to create a certain degree of expansion and contraction in response to foot movement. For example, common athletic shoe uppers often utilize this blended elastic fabric in certain areas to accommodate the flexion and extension of the foot during walking and running.

[0006] 2. Splicing and pleating design upper technology:

[0007] Some shoe upper designs achieve dynamic stretchability by splicing fabrics of different materials and shapes, or deliberately creating wrinkles and pleated structures. In spliced ​​shoe uppers, fabrics with different elasticity and stretchability are spliced ​​and combined according to the characteristics of the foot's movable joints (such as the toe and ankle). For example, a softer, more stretchable fabric is connected to other relatively stiff fabrics at the ankle to allow space for stretching when the ankle moves. The wrinkle and pleat design is achieved during the shoe upper forming process through a special folding and backlog process to form natural wrinkles on the shoe upper. When the foot moves, these wrinkles can expand or further deform to provide room for movement for the foot. Its production process involves precise cutting, meticulous splicing, and specific styling treatments, and the process complexity is relatively high.

[0008] 2. Deficiencies and Problems of Existing Technologies

[0009] 1. Deficiencies in elastic material upper technology:

[0010] While elastic fibers can impart a certain degree of stretchability to the shoe upper, this ability is relatively limited and can often only accommodate relatively small foot flexion and extension movements. During more intense movements, such as large twists and jumps, the upper's elastic stretchability can reach its limits, creating a noticeable sense of restraint on the foot and affecting wearing comfort. Furthermore, with increased frequency of wear and prolonged stretching, the elastic fibers are prone to elastic fatigue, causing the upper to gradually lose its original elasticity, significantly reducing its service life. Furthermore, uppers that rely solely on the elasticity of the material have relatively limited stretchability in different directions, making it difficult to adapt to the complex and diverse movements of the foot.

[0011] 2. Deficiencies in stitching and pleating design upper technology:

[0012] Due to the differences in physical properties between the joints of different fabrics, frequent foot movement can lead to unraveling and damage at these joints due to uneven force and repeated friction, compromising the overall structural integrity and aesthetics of the upper. While wrinkled and pleated uppers can provide some flexibility, prolonged compression and stretching can lead to deformation and difficulty in restoring the original shape, disrupting the original stretchability. Furthermore, these designs often result in the upper appearing less smooth and refined, making them less suitable for use in situations where aesthetics are paramount.

[0013] 3. Causes and Difficulties in Solving These Problems

[0014] 1. Cause analysis:

[0015] The fundamental reason for these shortcomings in existing technologies is that most attempt to address the dynamic expansion and contraction of shoe uppers from a relatively simplistic perspective, lacking in-depth consideration of the complex mechanics of foot movement and the synergy of the overall shoe upper structure. For example, elastic uppers rely solely on the physical properties of the material itself, without further expanding the expansion function through structural optimization. Meanwhile, splicing and pleating designs focus on creating localized movement space while neglecting the overall structural stability and appearance.

[0016] 2. Difficulties encountered in solving problems:

[0017] There are many challenges in trying to solve these problems. From a design concept perspective, it is not easy to break through traditional thinking and find an innovative design approach that fully considers the various movement patterns of the foot while also taking into account the stability and aesthetics of the upper structure. This requires interdisciplinary knowledge integration and innovative inspiration. In terms of material selection and process improvement, if a new material that can fully meet complex requirements is to be developed, or if existing processes are to be significantly optimized to solve the above problems, it involves collaborative research in multiple disciplines such as materials science and textile engineering. It requires a lot of time, manpower, and material resources for repeated testing and debugging, which is costly and technically difficult. Summary of the Invention

[0018] The present invention provides a shoe upper and a shoe with a segmented springtail structure, which solves the defect of the existing shoe upper technology that the shoe upper has poor adaptability to complex and diverse foot movement postures.

[0019] The technical solution of the present invention is achieved as follows:

[0020] The present invention firstly proposes a shoe upper with a springtail segmented structure, which comprises a plurality of segmented layers. The segmented layers are stacked together in sequence from the toe to the heel, and movable gaps are arranged between the segmented layers.

[0021] Preferably, with the toe direction as the front, the front end of the segmented layer is connected to the inner layer. The inner layer is an elastic knitted fabric layer.

[0022] Preferably, with the toe direction as the front and the heel direction as the back, the front portion of the back segmented layer is located below the back portion of the front segmented layer.

[0023] Preferably, the movable interval is 0.3-2 mm, and a plurality of air holes are provided on the segmented layer.

[0024] Preferably, the segmented layer is an elastic fabric layer.

[0025] Preferably, the elastic fabric layer is a blended fabric of polyester fiber and spandex fiber.

[0026] Preferably, the segmented layers correspond to both sides of the width of the shoe and are connected by a spacer layer.

[0027] Preferably, the spacer layer is an elastic gasket.

[0028] Preferably, the elastic gasket is an elastic cloth sheet or an elastic plastic sheet.

[0029] The present invention further provides a shoe comprising the above-mentioned upper with a segmented springtail structure and a sole, wherein the upper with a segmented springtail structure is fixed on the sole.

[0030] The beneficial effects of the present invention are as follows: the present invention utilizes the stable and orderly structural principles contained in the segmented structure of the springtail, so that each segmented layer can not only independently and flexibly perform expansion and contraction activities during exercise, but also maintain the firmness and stability of the overall structure during daily wear and repeated expansion and contraction; even after long-term and frequent foot movements, the upper will not fail to have the expansion and contraction function due to structural looseness, damage, etc., which significantly enhances the structural stability and durability of the upper, effectively extends the service life of the product, reduces the frequency of consumers replacing shoes due to damage to the upper, and improves the cost-effectiveness of the product.
