Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shoes, more particularly to an elastic insole and an odor-resistant sports shoe. BACKGROUND

[0002] At present, with the development of society, many people like to relieve stress through sports and exercise the body. When exercising, the performance of the shoes is very important. Among the various components of the shoes, the insole has the most outstanding influence on sports performance. The insole is located between the outsole and the upper, and plays a role in connecting the whole shoe and maintaining the stability of the structure.

[0003] The existing insole of sports shoes mainly has two important indicators, one is the cushioning performance, and the other is the rebound performance. The cushioning performance is used to buffer the impact force of the ground and the foot, provide comfortable foot feeling, and protect the foot and knee joint and other positions to avoid injury caused by sports. The rebound performance is the performance of producing rapid propulsion after stepping on the ground. High rebound performance can push the human body out faster, for example, it can improve the running speed to a certain extent. The two indicators above, the cushioning performance is mainly based on foaming material. The better the cushioning performance is, the softer the insole is, and the better the protection ability of the foot feeling is. The rebound performance is mainly based on hard materials such as carbon fiber plate. The faster the rebound speed is, the harder the insole is, and the foot feeling is harder but the sports performance is stronger.

[0004] At the same time, because sports shoes sweat a lot, after wearing for a period of time, there will be a smell left in the shoes. The existing way is to replace the insole to solve the problem, but in actual use, it is found that in most cases, sweat will penetrate through the insole to the surface layer of the insole, and the insole cannot be replaced, so that even if the insole is replaced, the smell is difficult to remove. Therefore, how to manufacture an insole and sports shoes that do not leave odor, are comfortable and have strong sports performance is the development trend of shoes. SUMMARY

[0005] In view of the deficiencies in the prior art, the present application provides an elastic insole and an odor-resistant sports shoe, which has the advantages of good rebound performance, comfortable foot feeling and no odor left, and can also meet the cushioning needs of heavy users.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an elastic insole, comprising a cushioning layer, an elastic substrate and a secondary elastic member, the elastic substrate comprises a lower support part and an upper support part protruding from the lower support part, the cushioning layer is arranged below the upper support part, and the secondary elastic member is arranged above the upper support part.

[0007] The present invention is further configured such that: the upper support portion is disposed on both sides of the lower support portion, the upper support portion on both sides corresponds to the ball of the foot and the heel portion respectively, and the lower support portion corresponds to the arch portion.

[0008] The present invention is further configured such that: a connecting part is provided between the lower support part and the upper support part to connect the two, and a groove extending along the length direction is provided on the connecting part, and the portions at both ends of the groove extend to the upper support part and the lower support part.

[0009] The present invention is further configured such that: the secondary elastic element is configured as a tubular structure and has a plurality of them, and the plurality of the secondary elastic elements are arranged adjacently to cover the upper surface of the upper support.

[0010] The present invention is further configured such that the secondary elastic element is configured as a hollow tubular structure.

[0011] The present invention is further configured such that the cross-section of the secondary elastic member is a polygonal structure or a circle or an ellipse.

[0012] The present invention is further configured such that the upper surface of the shock-absorbing layer increases in height from the inside to the outside, so that the upper support portion located above the shock-absorbing layer is in an inclined state.

[0013] The present invention is further configured such that: an adhesive layer is provided above the elastic substrate and the secondary elastic element, and the adhesive layer is provided with a fitting part corresponding to the position of the arch of the foot, and the fitting part is fitted above the lower support part.

[0014] The present invention is further configured such that: the elastic substrate has a fast elastic deformation recovery rate, and the secondary elastic element has a relatively slow elastic deformation recovery rate compared to the elastic substrate.

[0015] The present invention further provides an odor-resistant sports shoe, wherein the midsole of the sports shoe is composed of the above-mentioned elastic midsole, and the surface layer of the interlocking part is added with plant microcapsule antibacterial material.

[0016] In summary, the present invention has the following beneficial effects: The midsole of this invention comprises an elastic base plate and a secondary elastic element. The secondary elastic element is positioned on the upper support portion of the elastic base plate, with the elastic base plate preferably having a faster elastic deformation recovery rate. When the user's foot or heel steps on the sole, the secondary elastic element and the elastic base plate deform together, accumulating rebound energy. During recovery, the elastic base plate rebounds rapidly, providing an explosive, direct propulsive force, followed by a secondary rebound from the secondary elastic element, resulting in a more lasting rebound effect. Simultaneously, the secondary elastic element neutralizes the overly firm feel of the elastic base plate, increasing comfort.

[0017] Meanwhile, the present invention provides a shock-absorbing layer below the upper support portion of the elastic substrate. This shock-absorbing layer only takes effect after the secondary elastic element and the elastic substrate are deformed. Therefore, for users with low weight who do not require strong shock absorption, this shock-absorbing layer will not cause a decrease in rebound performance. However, for users with higher weight who require stronger shock absorption, this shock-absorbing layer can play a shock-absorbing role after both the secondary elastic element and the elastic substrate are deformed, thereby protecting the feet and knees from impact.

[0018] The invention also adds plant microcapsule antibacterial material to the surface of the interlocking part of the midsole. Adding this material to the surface can prevent bacteria, odors and other substances from remaining in the midsole, so that users can solve the odor problem inside the shoe by simply changing the insole.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This embodiment discloses an elastic midsole, such as Figures 1-4As shown, the structure includes a cushioning layer 1, an elastic substrate 2, and a secondary elastic element 3. The elastic substrate 2 includes a lower support portion 21 and an upper support portion 22 that protrudes from the lower support portion 21. The cushioning layer 1 is disposed below the upper support portion 22, and the secondary elastic element 3 is disposed above the upper support portion 22. In the above structure, the elastic substrate 2 can be made of carbon fiber material. Carbon fiber is lightweight and has excellent stiffness and toughness, so the elastic substrate 2 made of carbon fiber can form a good support capacity and maintain structural stability. The carbon fiber plate also has the properties of rapid rebound and resistance to elastic fatigue, giving the midsole excellent rebound performance. The secondary elastic component 3, based on this, can be made of thermoplastic polyester elastomer (TPEE), which has excellent resilience but is softer than carbon fiber plate. When the runner pushes off the ground, the elastic base plate 2 acts as the main force, providing explosive direct propulsion; while the secondary elastic component assists, responsible for adding a secondary rebound effect on the basis of rapid rebound. In order to make the rebound force more durable and comfortable, the elastic base plate 2 has a fast elastic deformation recovery rate, while the secondary elastic component 3 has a relatively slower elastic deformation recovery rate. Just like the characteristics of carbon plate and TPEE materials, if there is only the rapid rebound of carbon plate, it is more of a hard-on-hard feel. Although the rebound speed is fast, the duration is short and the feel is average. The setting of the secondary elastic component solves this problem well, which makes the midsole extend the rebound duration and the feel is softer. Meanwhile, the cushioning layer 1 can be made of EVA material produced using a supercritical foaming process, providing a very soft and lightweight feel and excellent cushioning performance. Positioning it below the upper support 22 caters to the needs of heavier users. When a heavier user deforms both the secondary elastic element 3 and the elastic base plate 2, it provides cushioning, protecting the user's feet and knees. Positioning the cushioning layer 1 below the elastic base plate 2 also suits lighter users. Because the cushioning layer only becomes effective after the secondary elastic element and elastic base plate deform, it does not cause a decrease in rebound performance for lighter users who do not require strong cushioning. This allows the elastic midsole of this embodiment to meet the needs of users of different weights.

[0026] Furthermore, refer to Figure 1 and Figure 3 The upper support portion 22 is located on both sides of the lower support portion 21, with the upper support portion 22 on both sides corresponding to the ball of the foot and the heel, respectively, and the lower support portion 21 corresponding to the arch of the foot. Through the above structure, the upper support portion 22 forms a wing-shaped structure that spreads out to both sides. When the ball of the foot and the heel step on the ground, the upper support portion 22 can deform better to accumulate energy and generate rebound.

[0027] Furthermore, refer to Figure 2 and Figure 4A connecting portion 23 is provided between the lower support portion 21 and the upper support portion 22, connecting the two. A groove 231 extending along the length direction is provided on the connecting portion 23, and the two ends of the groove 231 extend to the upper support portion 22 and the lower support portion 21. The function of the groove 231 is to guide the connecting portion 23 and parts of the upper support portion 22 and the lower support portion 21 to undergo lateral deformation. Because the deformation of the midsole is not entirely subjected to vertical force, but also to lateral bending force, after the groove is provided, when the user applies pressure to the midsole in the lateral direction, the elastic substrate 2 will generate different deformations and provide different degrees of support at intervals of the groove 231, so that the elastic substrate can conform to the user's foot. Preferably, the cross-section of the groove is set as a V-shaped structure. In this way, while satisfying the deformation of the elastic substrate 2 in the direction of the groove, the V-shape removes less material and does not affect the structural strength too much.

[0028] Furthermore, the secondary elastic element 3 is configured as a tubular structure and comprises several such elements, arranged adjacently to cover the upper surface of the upper support portion 22. The tubular structure better disperses stress, preventing excessive local deformation, and the multiple tubular secondary elastic elements 3 maintain excellent elastic performance. Preferably, the secondary elastic element 3 can be configured as a hollow tubular structure, which reduces weight while maintaining performance, thus contributing to the lightweight design of athletic shoes. Simultaneously, the cross-section of the secondary elastic element 3 can be flexibly configured as needed, such as various polygonal structures, circles, or ellipses, with a hexagonal structure being optimal. This hexagonal structure offers excellent deformation recovery performance, a flat surface, is less prone to rolling, facilitates positioning during processing, and allows for integration with the elastic substrate 2.

[0029] Furthermore, refer to Figure 1 and Figure 3 The upper surface of the damping layer 1 increases in height from the inside out, so that the upper support 22 located above the damping layer 1 is inclined. Figure 3 The included angle α between the upper support part 22 and the connecting part 23 is greater than 90 degrees. This structure allows the upper support part 22 to have a larger space for downward deformation. Because the inclined structure generates a rebound force in the vertical direction and a rebound component force in the horizontal direction, the user can more easily change direction and adjust according to the wearing feeling, thus improving flexibility.

[0030] Furthermore, an adhesive layer 4 is provided above the elastic substrate 2 and the secondary elastic element 3. The adhesive layer 4 has a fitting portion 41 corresponding to the arch of the foot, and the fitting portion 41 is fitted above the lower support portion 21. The adhesive layer 4 can be made of conventional foam material. It is located at the top and closest to the user's foot, its function being to provide a more comfortable feel for the user. No special performance is required. The fitting portion 41 serves to make the bonding between the adhesive layer 4 and the elastic substrate 2 more tightly, and the fitting portion 41 can also be slightly raised to better support the user's arch.

[0031] It should be noted that the midsole in this embodiment is not limited to a specific composite method. It can be composited and fixed by mature adhesive composite, in-mold composite or mechanical composite methods in the art. This embodiment does not make any additional limitations.

[0032] When used alone as a shoe midsole, only midsole performance needs to be considered. However, when manufactured into a finished sports shoe, the issue of odor residue also needs to be considered. Therefore, this embodiment further provides an odor-resistant sports shoe. The midsole of the sports shoe is composed of the aforementioned elastic midsole. After being manufactured into a finished sports shoe, the surface layer of the interlocking part preferably has plant microcapsule antibacterial material added. For example, the surface layer of the interlocking part is composite fiber fabric, and then plant microcapsule antibacterial material is added to the fabric. The existing mature microencapsulation technology is used, and natural plant extracts such as artemisia oil, tea tree oil, isatis root extract, cinnamon oil, and licorice extract are selected. The midsole is guaranteed to be odor-free through microcapsule slow release. In this way, when manufactured into a finished sports shoe, it not only has excellent elastic cushioning performance, but also solves the problem of odor residue in the shoe midsole, and has a good prospect for promotion and application.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
