Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a lightweight anti-torsion sole and a sports shoe comprising the sole. Background Art

[0002] Sports shoes are shoes that people wear when doing sports, and they play a vital role in improving sports performance and reducing sports injuries. Studies have shown that when the midsole hardness of sports shoes is smaller, sports shoes have better cushioning and sports protection effects.

[0003] However, for some sports with large movements and complex movements, sports shoes need to provide athletes with more performance support in other aspects. For example, badminton is a sport that requires very high physical fitness and skills. Athletes need to perform various complex movements such as sudden stops, jumps and changes of direction on the court, such as active attack, defense, large-scale twisting and stretching of the body, accompanied by short-term, intermittent high-intensity, multi-directional running. Therefore, badminton shoes are not only required to be lightweight and breathable, but also need to have quick start and stability.

[0004] Existing sports shoes are basically unable to meet the above requirements at the same time, and usually have functional limitations. For example, most quick-start sports shoes are developed in the direction of lightweight, but have disadvantages in foot cushioning performance and stability, while stable protection sports shoes are just the opposite.

[0028] In order to better understand the purpose, structure and function of the present invention, the lightweight anti-torsion sole and sports shoes of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 7 The sports shoes in the utility model shown in the figure include a lightweight anti-torsion sole and an upper 7 arranged on the sole. The lightweight anti-torsion sole includes a midsole 3, which is made of a foam material and can provide a certain shock absorption and rebound effect for the human foot during exercise. The midsole 3 includes a forefoot part, a midfoot part and a heel part. The forefoot part of the midsole 3 is provided with a first matching position 31, and the first matching position 31 is provided with a first buffer 5. The heel part of the midsole 3 is provided with a second matching position 32, and the second buffer 6 is provided in the second matching position 32.

[0030] The density of the first buffer 5 and the second buffer 6 is less than that of the midsole 3, and the resilience of the first buffer 5 and the second buffer 6 is stronger than that of the midsole 3. Specifically, the first buffer 5 and the second buffer 6 can be made of a thermoplastic elastomer foamed shoe material disclosed in the patent document with publication number CN111117215A, or made of a lightweight, highly elastic, compression-resistant foamed shoe material disclosed in the patent document with publication number CN114573904B. Of course, other lightweight, highly elastic materials with lower density can also be used.

[0031] Since the sole of the utility model is provided with the first buffer component 5 and the second buffer component 6 at the forefoot part and the heel part of the midsole 3 respectively, and the rebound effect and lightness of both are better than the foam material used in the midsole 3, the midsole 3 of the sole can greatly improve the buffering performance and lightness while maintaining strong stability.

[0032] Further, if Figure 1 and Figure 2 As shown, the first matching position 31 of the forefoot part of the midsole 3 is a through groove that runs through the upper and lower surfaces of the midsole 3, and the first buffer 5 is embedded in the first matching position 31 and nested with the first matching position 31. The upper surface and lower surface of the first buffer 5 extend to the upper surface and lower surface of the forefoot part of the midsole 3, respectively, so as to fit the insole at the upper part of the midsole 3 and the outsole 1 at the lower part of the midsole 3, respectively. With this arrangement, the effect of the first buffer 5 can be fully exerted, and the stretching and rebound elasticity of the forefoot part of the sole during exercise can be better enhanced, thereby improving sports performance.

[0033] Further, if Figure 1 and Figure 3 As shown, the upper surface of the first buffer 5 is also provided with a plurality of transverse hollow lines 51 arranged side by side, and "transverse" refers to the extending direction from the inner side of the human foot to the outer side (or the outer side to the inner side). An insole is provided on the upper part of the midsole 3, and the upper surface of the first buffer 5 is fitted with the insole. The transverse hollow lines 51 can enhance the mechanical coupling between the insole and the first buffer 5, that is, the mechanical coupling between the insole and the forefoot part of the midsole 3 can be enhanced, thereby achieving the effect of reducing the displacement of the insole.

[0034] Further, if Figure 1 As shown, the second matching position 32 of the heel part of the midsole 3 is a groove structure, and the second buffer 6 is embedded in the second matching position 32. The second buffer 6 cooperates with the second matching position 32 to help reduce the impact force on the heel when touching the ground and enhance the protection effect of the heel.

[0035] Preferably, if Figure 4As shown, the end of the second buffer 6 near the human heel is set as an arc structure 61, and the curvature of the arc structure 61 matches the curvature of the human heel, that is, the arc structure 61 at the end of the second buffer 6 fits the anatomical structure of the human heel. This arrangement helps to enhance the transition of the heel of the sole when touching the ground, and further reduces the probability of sports injuries.

[0036] Further, if Figure 1 and Figure 5 As shown, a first support member 4 is provided above the midfoot portion of the midsole 3. The first support member 4 is preferably made of TPU material, and may also be made of other hard materials. It has certain strength and toughness, and can provide support for the arch of the human foot. The first support member 4 includes a main body, which is fitted with the upper surface of the midfoot portion of the midsole 3 to enhance the stability of the sole structure. The main body is provided with a plurality of strip-shaped longitudinal hollow structures 41 arranged side by side. "Longitudinal" refers to the extension direction of the toe of the human foot pointing to the heel (or the heel pointing to the toe). The longitudinal hollow structure 41 can not only reduce the weight of the first support member 4, but also provide appropriate flexibility for the arch portion, while improving the stability and comfort of the midfoot portion of the sole.

[0037] Two first extensions 42 are arranged on one side of the main body of the first support member 4 near the forefoot portion of the midsole 3, and the two first extensions 42 extend toward the inner side and the outer side of the upper surface of the first buffer member 5, respectively, so that the first extensions 42 and the upper surface of the first buffer member 5 are arranged in close contact with each other; two second extensions 43 are arranged on one side of the main body near the heel portion of the midsole 3, and the two second extensions 43 extend to the second buffer member 6, and are arranged in close contact with the inner side wall and the outer side wall of the second buffer member 6, respectively. The inner side wall of the second buffer member 6 is the side wall corresponding to the inner side of the human foot, and the outer side wall of the second buffer member 6 is the side wall corresponding to the outer side of the human foot. The first extension portion 42 and the second extension portion 43 can greatly enhance the fit between the first support member 4 and the first buffer member 5 and the second buffer member 6, while improving the connection stability of the first support member 4; in addition, the first extension portion 42 and the second extension portion 43 can also provide support for the buffering and rebound of the midsole 3 and the first buffer member 5, 6, thereby improving the rebound effect and service life of the midsole 3 and the first buffer member 5, 6.

[0038] Further, if Figure 1 and Figure 6As shown, the lower part of the midsole 3 is fitted with an outsole 1, which is made of a rubber material with good wear resistance and anti-slip properties, and extends from the forefoot part of the midsole 3 to the heel part. A countersunk hole 11 is provided at the midfoot part of the outsole 1, and a second support member 2 is embedded in the countersunk hole 11. The second support member 2 corresponds to the first support member 4 in the vertical direction, forming a double anti-torsion structure. The double anti-torsion structure helps to enhance the anti-torsion performance of the sole, increase the supporting and protective effect of the sole on the midfoot part of the human body, improve stability, and reduce sports injuries. The second support member 2 is roughly rectangular, and is preferably made of high-strength carbon fiber material. The second support member 2 and the countersunk hole 11 on the outsole 1 are nested with each other, which helps to further improve the anti-torsion performance of the sole.

[0039] like Figure 6 As shown, at least one support bar 12 is provided in the countersunk hole 11 of the outsole 1, and at least one support bar 12 divides the countersunk hole 11 into at least two hollow structures. Preferably, two support bars 12 are evenly spaced in the countersunk hole 11. The support bar 12 cooperates with the countersunk hole 11 to couple the mechanical properties with the second support member 2, which helps to reduce the stress and strain of the second support member 2 and improve the torsional strength and service life of the second support member 2.

[0040] The front side, medial side and heel of the forefoot part of the outsole 1 are extended toward the midsole 3 to wrap the side wall of the midsole 3 and enhance the protection of the outsole 1 to the midsole 3. Preferably, a side wall 13 is provided on the outer side of the forefoot part of the outsole 1. The side wall 13 is extended upward from the ground toward the human foot to fit with the outer side wall of the midsole 3. The side wall 13 can enhance the anti-skid and anti-rollover performance of the sports shoe sole during lateral movement; an opening 14 is also provided in the middle of the side wall 13. The opening 14 is arranged in the vertical direction to separate the side wall 13 into two parts in the longitudinal direction of the sole. Based on the anatomical structure and functional characteristics of the forefoot of the human foot, the opening 14 on the side wall 13 helps to enhance the bending flexibility of the forefoot of the foot during exercise and further improve the kicking and stretching effect.

[0041] The utility model also discloses a sports shoe, which comprises a shoe upper 7 and the above-mentioned lightweight anti-torsion sole, wherein the shoe upper 7 is arranged on the sole. Figure 1 and Figure 7 As shown, the upper 7 is made of a lightweight, breathable, high-toughness fabric, which can reduce the overall weight of the sports shoe while ensuring the breathability and service life of the upper 7. The upper 7 is provided with a shoelace system 9 for convenient adjustment of tightness at the instep of the human body, and the heel portion of the upper 7 is also provided with a heel stabilizing component 8 to further improve the stability of the upper 7.

[0042] The lightweight anti-torsion sole and sports shoes of the utility model have the following advantages:

[0043] 1. By arranging the first and second buffer components with a rebound coefficient and lightness superior to those of traditional foam materials at the forefoot and heel parts of the midsole, the overall buffering performance of the sole is greatly improved, while the weight of the sole is reduced.

[0044] 2. The dual anti-torsion structure design of the first support member and the second support member greatly improves the anti-torsion performance of the sole, further enhances the stability of the sole, and reduces sports injuries.

[0045] 3. The side wall structure design of the outsole enhances the anti-slip and anti-rollover performance of the sole during lateral movement, and the bending flexibility of the forefoot part of the sole during exercise is enhanced, improving the pushing and stretching effect.

[0046] 4. The structural design of the first support member can provide stable support for the arch of the foot while ensuring appropriate flexibility and improving comfort.
