Description

Technical Field

[0001] This invention relates to an elastic shoe, and more particularly to an elastic sole and an elastic shoe, belonging to the field of shoemaking technology. Background Technology

[0002] Shoes are essential clothing items in people's daily lives. As the core component of a shoe, the sole directly determines its shock absorption, rebound performance, and wearing comfort. Currently, most elastic soles on the market are made of a single, integral foam material, with uniform elastic parameters, making it impossible to differentiate them according to the stress characteristics of the human foot. During walking and exercise, the forefoot is responsible for pushing off the ground, the heel absorbs the impact upon landing, and the arch of the foot cushions and supports the foot. The intensity and form of stress in these three areas differ significantly.

[0003] Existing traditional shoe soles have the following defects: First, the overall elasticity is uniform, and the heel cushioning is insufficient. When landing, the impact force is directly transmitted to the ankle and knee, which can easily cause joint strain. Second, the forefoot is too hard and lacks elasticity, resulting in poor feedback when pushing off the ground and increasing the physical exertion of walking. Summary of the Invention

[0004] The purpose of this invention is to provide an elastic sole and elastic shoes to solve the problems mentioned in the background art, namely: firstly, the overall elasticity is uniform, the heel cushioning is insufficient, and the impact force is directly transmitted to the ankle and knee when landing, which can easily cause joint strain; secondly, the forefoot is too hard and lacks elasticity, resulting in poor feedback when pushing off the ground and increasing the physical exertion of walking.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elastic sole and an elastic shoe, comprising an upper, a wear-resistant outsole disposed below the upper, an elastic midsole disposed inside the wear-resistant outsole, a heel area and a forefoot area disposed inside the elastic midsole, a plurality of mounting grooves being provided at the top of the heel area, a reinforcing spring being provided at the bottom of the inner wall of the mounting groove, an elastic base being provided at the top of the reinforcing spring, a plurality of elastic cavities being provided inside the elastic base, and an elastic column being provided inside the elastic cavity.

[0006] As a preferred embodiment of the present invention, the elastic column is made of high-elastic EVA foam particles, and the reinforcing sheet is made of TPU material.

[0007] As a preferred embodiment of the present invention, a plurality of equidistant and uniform first elastic buffer cavities are provided on one side of the bottom of the wear-resistant outsole, and the first elastic buffer cavities are elliptical hollow structures. A second buffer cavity corresponding to the first elastic buffer cavity is provided at the bottom of the forefoot area.

[0008] As a preferred embodiment of the present invention, the elastic midsole, heel area and forefoot area are all integrally injection molded from high-elastic foam material.

[0009] As a preferred embodiment of the present invention, the wear-resistant outsole is made of rubber.

[0010] As a preferred embodiment of the present invention, a first wear-resistant pad is provided on one side of the bottom end of the wear-resistant outsole, and a plurality of spaced and uniform first anti-slip patterns are provided on the bottom end of the first wear-resistant pad.

[0011] As a preferred embodiment of the present invention, a second wear-resistant pad is provided on the other side of the bottom end of the wear-resistant outsole, and the bottom end of the second wear-resistant pad is provided with a plurality of spaced and uniform second anti-slip patterns.

[0012] As a preferred embodiment of the present invention, the middle part of the wear-resistant outsole is set in the shape of an arch, and the heel area and the forefoot area are also embedded with arc-shaped springs made of carbon fiber.

[0013] Compared with related technologies, the elastic sole and elastic shoe provided by the present invention have the following beneficial effects: 1. By incorporating an installation groove in the heel area of ​​the elastic midsole, and internally integrating a TPU reinforced spring and an elastic base with built-in elastic pillars, the multi-level cushioning structure of the elastic cavity and pillars, along with pre-embedded carbon fiber arc-shaped springs, can comprehensively absorb the impact force generated when the sole lands, effectively weakening the ground reaction force and preventing the impact force from being directly transmitted to the ankle and knee joints. Simultaneously, the high-elasticity EVA foam material has excellent deformation recovery capabilities, which, combined with the reinforcement of the springs and carbon fiber springs, not only solves the problems of insufficient heel cushioning and elasticity imbalance in traditional soles, but also enables rapid energy storage and recovery, improving heel rebound performance, reducing the load on joints during prolonged walking and exercise, preventing joint strain, and protecting the wearer's lower limb health.

[0014] 2. Secondly, elliptical hollow structures are respectively set in the wear-resistant outsole and the forefoot area of ​​the elastic midsole, forming a first and second elastic cushioning cavity. The two-layer hollow cushioning cavities work together to effectively reduce the overall hardness of the forefoot area and optimize the forefoot elasticity. This structure not only disperses the local pressure on the forefoot, alleviating foot soreness and fatigue caused by prolonged walking, but also reduces the resistance when the foot pushes off the ground, improves the feedback of the push-off force, and reduces the wearer's physical exertion during walking and exercise. Moreover, the elliptical hollow structure has a larger deformation space, stronger fault tolerance, and can adapt to multi-angle foot force movements, making it suitable for various usage scenarios such as running and daily walking.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-6 The present invention provides an elastic sole and an elastic shoe, including an upper 1, a wear-resistant outsole 2 below the upper 1, an elastic midsole 3 inside the wear-resistant outsole 2, a heel area 4 and a forefoot area 5 inside the elastic midsole 3, a plurality of mounting grooves 6 at the top of the heel area 4, a reinforcing spring 8 at the bottom of the inner wall of the mounting groove 6, an elastic base 7 at the top of the reinforcing spring 8, a plurality of elastic cavities 9 inside the elastic base 7, and an elastic column 10 inside the elastic cavity 9. By sequentially setting a wear-resistant outsole 2 and an elastic midsole 3 below the upper 1, and by opening several mounting grooves 6 at the top of the heel area 4 of the elastic midsole 3, and assembling a reinforcing spring 8 at the bottom of the inner wall of the mounting groove 6, and installing an elastic base 7 at the top of the reinforcing spring 8, the elastic base 7 can absorb and buffer the impact force generated by the heel landing in multiple layers through several elastic cavities 9 and its built-in elastic columns 10, effectively weakening the ground reaction force and preventing the impact force from being directly transmitted to the ankle and knee joints. At the same time, it can improve the rebound performance of the heel area 4, and can quickly store energy and return to its original position when the foot pushes off the ground, thus optimizing the user experience of walking and exercising.

[0019] The elastic column 10 is made of high-elastic EVA foam particles, and the reinforcing elastic piece 8 is made of TPU material; The elastic pillar 10 is made of high-elastic EVA foam particles, which are lightweight, have a high elasticity coefficient, and excellent deformation recovery performance, making them resistant to collapse and permanent deformation under long-term pressure. The reinforcing spring 8 is made of TPU material, which is tough, tensile-resistant, and wear-resistant, providing both support and cushioning. Together, these two materials ensure the overall cushioning and rebound capability of the heel area 4, extend the lifespan of components, reduce the probability of sole aging and damage, and decrease replacement costs in the later stages of use.

[0020] The wear-resistant outsole 2 has several equidistant and uniform first elastic buffer cavities 11 on one side of its bottom, and the first elastic buffer cavity 11 is an elliptical hollow structure. The bottom of the forefoot area 5 has a second buffer cavity corresponding to the first elastic buffer cavity 11. The wear-resistant outsole 2 has several equidistantly distributed elliptical hollow first elastic buffer cavities 11 on one side of its bottom. At the same time, a second buffer cavity corresponding to the first elastic buffer cavity 11 is opened on the bottom of the forefoot area 5. The two-layer buffer cavities work together to further reduce the overall hardness of the forefoot area 5, reduce the resistance when the foot pushes off the ground, disperse the local pressure on the forefoot, and relieve foot soreness and fatigue caused by long-term walking. At the same time, the elliptical hollow structure has a larger deformation space, higher cushioning tolerance, and is suitable for multi-angle foot force exertion movements.

[0021] The elastic midsole 3, heel area 4, and forefoot area 5 are all made of high-elastic foam material through one-piece injection molding. The elastic midsole 3, heel area 4, and forefoot area 5 are all made of high-elastic foam material through one-piece injection molding. The one-piece molding structure eliminates scattered spliced ​​parts, resulting in higher overall structural strength and making it less prone to structural cracking and part detachment. At the same time, the one-piece injection molding process simplifies the production process, reduces assembly difficulty and production losses, and lowers the cost of mass production. In addition, the high-elastic foam material is lightweight, which can reduce the overall weight of the shoe and further improve wearing comfort.

[0022] The wear-resistant outsole 2 is made of rubber. The durable outsole 2 is made of rubber, which has excellent wear resistance, tear resistance and anti-slip properties. It can effectively resist the wear of outdoor sand and rough ground on the sole and extend the overall service life of the sole. At the same time, the rubber material has a certain degree of flexibility and can deform synchronously with the bending of the foot, adapting to the dynamic bending of the foot during walking and exercise, without the sole becoming stiff or stuck when bending.

[0023] The wear-resistant outsole 2 has a first wear-resistant pad 12 on one side of its bottom end, and the bottom end of the first wear-resistant pad 12 has several spaced and uniform first anti-slip patterns 13. By setting a first abrasion-resistant pad 12 on one side of the bottom of the abrasion-resistant outsole 2, and opening a number of spaced and evenly distributed first anti-slip patterns 13 on the bottom of the first abrasion-resistant pad 12, the abrasion-resistant pad can specifically enhance the abrasion resistance of local areas, and the first anti-slip patterns 13 can increase the friction between the sole and the contact surface, improve the grip performance of the sole, effectively prevent the wearer from slipping and falling when walking on a smooth surface, and improve the safety of wearing.

[0024] On the other side of the bottom end of the wear-resistant outsole 2, there is a second wear-resistant pad 14, and the bottom end of the second wear-resistant pad 14 is provided with several spaced and uniform second anti-slip patterns 15. By setting a second wear-resistant pad 14 on the other side of the bottom of the wear-resistant outsole 2, and configuring several spaced and evenly distributed second anti-slip patterns 15 at the bottom of the second wear-resistant pad 14; the differentiated layout of the second wear-resistant pad 14 and the second anti-slip patterns 15 can adapt to different ground environments, taking into account both drainage and anti-slip functions, and can quickly drain water accumulated inside the patterns, eliminating the problem of slipping due to water accumulation. It is suitable for various usage scenarios such as indoor tiles, outdoor pavement, and wet ground, thus broadening the product's application range.

[0025] The wear-resistant outsole 2 has an arch-shaped design at the bottom center, and the heel area 4 and forefoot area 5 are also embedded with carbon fiber curved springs. By designing the middle of the wear-resistant outsole 2 into an arch-shaped structure that conforms to the physiological curvature of the human foot arch, it can accurately support the user's arch area, distribute the pressure on the arch, and prevent arch pain and strain caused by prolonged wear. At the same time, carbon fiber arc-shaped springs are embedded in the heel area 4 and the forefoot area 5. The carbon fiber springs are high-strength, lightweight, and have good rebound effect, which can realize the linkage of force between the forefoot and heel, enhance the overall support of the sole, limit excessive deformation of the sole, and further improve the overall shock absorption and torsional resistance.

[0026] When in use, by setting the mounting groove 6 in the heel area 4 of the elastic midsole 3, and the internal TPU material reinforced elastic plate 8 and the elastic base 7 with built-in elastic column 10, relying on the multi-level cushioning structure of the elastic cavity 9 and the elastic column 10, the impact force generated when the sole lands can be absorbed in all directions, effectively weakening the ground reaction force and preventing the impact force from being directly transmitted to the ankle and knee joints from the root. Secondly, the elastic midsole 3, heel area 4, and forefoot area 5 are all made of high-elastic foam material and molded in one piece through an integrated injection molding process. Compared with the traditional multi-part splicing and assembly sole structure, the integrated molding design eliminates scattered splicing parts, resulting in a stronger overall structure and significantly improved structural strength. This effectively avoids problems such as sole cracking, part detachment, and delamination that may occur during daily use. At the same time, the integrated injection molding process is simple, requiring no additional assembly parts, which greatly reduces the difficulty of production and assembly and the loss of raw materials, facilitating mass production and effectively controlling production costs. Furthermore, the high-elastic foam material is lightweight and does not add extra weight to the sole, reducing the burden on the wearer's feet and further improving wearing comfort. The durable outsole 2 is made entirely of rubber, a preferred material for shoe outsoles. Rubber offers excellent wear resistance, tear resistance, and slip resistance, protecting the outsole from wear and scratches caused by outdoor gravel, rough surfaces, and step edges, thus extending its overall lifespan. Simultaneously, the rubber material possesses moderate flexibility, allowing it to deform in sync with dynamic foot movements such as walking, bending, and jumping. This adapts to the multi-angle bending needs of the foot, completely resolving the issues of stiffness, chafing, and binding caused by rigid outsoles, making it suitable for various dynamic walking and sports activities. A first abrasion-resistant pad 12 is fixedly installed on the rear side of the bottom of the abrasion-resistant outsole 2. The bottom of the first abrasion-resistant pad 12 has several spaced and evenly distributed first anti-slip patterns 13. The first abrasion-resistant pad 12 is made of high-hardness abrasion-resistant rubber material, which can specifically enhance the abrasion resistance of the heel area of ​​the sole and extend the service life of the easily worn parts of the heel. The matching first anti-slip patterns 13 can increase the friction between the sole and the contact surface, enhance the heel grip, prevent the wearer from slipping when standing and landing, and improve basic wearing safety. Correspondingly, a second wear-resistant pad 14 is fixedly installed on the front side of the bottom of the wear-resistant outsole 2. The bottom of the second wear-resistant pad 14 is provided with several evenly spaced second anti-slip patterns 15. The second wear-resistant pad 14 and the second anti-slip patterns 15 in the forefoot area can improve the wear resistance and grip performance of the forefoot. The durable outsole 2 features an ergonomically designed arch support structure in the middle, with the arch curvature matching the physiological curvature of an adult's foot. Simultaneously, carbon fiber curved springs are embedded within the heel area 4 and forefoot area 5. In actual use, the arch support structure perfectly conforms to the user's arch, evenly distributing pressure and preventing foot fatigue and strain caused by prolonged walking or standing. The embedded carbon fiber curved springs are lightweight, high-strength, fast-rebounding, and have excellent torsional resistance, enabling coordinated force distribution between the forefoot and heel, enhancing overall sole support, limiting excessive deformation, preventing sole collapse, and further improving overall shock absorption and torsional resistance, thus comprehensively optimizing the wearer's experience.
