Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a sole capable of improving stability and ground-pushing feedback, and a badminton shoe comprising the sole. Background Art

[0002] Sports shoes are shoes that people wear when doing sports. They are usually soft and elastic and have a certain cushioning effect. Different sports have different sports characteristics. Designing sports shoes for different sports characteristics can not only reduce sports injuries, but also help improve the wearer's sports performance.

[0003] Take badminton as an example. Badminton is a non-contact sport that requires jumping. It is also the fastest sport among racket sports. Badminton footwork changes frequently and relies on the mutual coordination between the joints of the lower limbs, as well as the interaction between the lower limbs as a whole and the surrounding environment (such as sports shoes, floor mats and other sports surfaces). In badminton, the badminton lunge is one of the most common footwork exercises, accounting for 15% of the total number of movements in a single game. In the badminton lunge, when violent impact is involved, the repeated sudden back and forth movement will bring harmful loads to the athlete's lower limbs, leading to a high incidence of lower limb injuries. Therefore, in badminton, sports shoes with good shock absorption and stability performance are needed to reduce the impact load on the lower limbs.

[0004] In order to improve the shock absorption effect and stability performance, existing sports shoes usually increase the grip and friction effect of sports shoes by changing the wear resistance of the outsole rubber and the outsole texture; improve the shock absorption effect of sports shoes by changing the performance of the midsole material or the hardness of the material; and improve the bending and torsion resistance of the midfoot by adding carbon plates or TPU materials to the middle waist of the sole. However, the above-mentioned improvements in structure or materials are all general improvements of sports shoes, aiming to improve the shock absorption and stability of general sports shoes. There is a lack of targeted improvements for badminton, and it is difficult to assist badminton players to better perform different step techniques and complete fast moving shots, and it is difficult to prevent potential injuries while ensuring the stability of the movement.

[0028] In order to better understand the purpose, structure and function of the present invention, the sole and badminton shoes of the present invention which can improve stability and ground feedback are described in detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 3As shown, the sole of the utility model that can improve stability and ground-pushing feedback includes a midsole 1 and an outsole 2. The outsole 2 is arranged at the lower part of the midsole 1 and is arranged in contact with the lower surface of the midsole 1. Among them, the midsole 1 includes a forefoot part, a midfoot part and a heel part. The forefoot part includes a main body and a support part. The support part is arranged on the outside or inside of the main body, and can also be arranged on the outside and inside at the same time. The support part has a first density, and the main body has a second density. The first density is greater than the second density. The main body is light, soft and elastic, and can provide shock absorption and rebound effects for the foot. The hardness of the support part is greater than the hardness of the main body, so as to provide better stable support for the human foot in the lateral direction of the forefoot part of the sole and provide a stronger ground-pushing feedback effect.

[0030] like Figure 4 As shown, preferably, the support portion 11 is arranged on the outside of the main body portion 12, and the sole can provide better stable support for the human foot on the outside of the forefoot. In particular, when an athlete performs a lunge, which is common in badminton, for example, the outer area of ​​the forefoot of the human foot will be subjected to severe impact. By strengthening the support of the outer area of ​​the forefoot of the sole through the support block, the stability of the foot can be improved, sports injuries can be reduced, and an upward and inward feedback force can be provided to the foot, thereby increasing the speed of movement change and thus improving sports performance.

[0031] Furthermore, the support portion 11 is a wedge-shaped structure, which is embedded in the main body portion 12 at the forefoot portion. The wedge-shaped structure is tapered as a whole, including a bottom and a top. The bottom is wider and longer, and is arranged toward the direction of the side wall of the midsole 1. The top is narrower and shorter, and is extended from the side wall of the midsole 1 toward the middle of the midsole 1.

[0032] Preferably, the bottom of the wedge-shaped structure extends to the side wall of the midsole 1, that is, the surface of the bottom of the wedge-shaped structure constitutes a part of the side wall of the midsole 1; the upper surface of the wedge-shaped structure extends to the upper surface of the midsole 1, that is, the upper surface of the wedge-shaped structure constitutes a part of the upper surface of the forefoot portion of the midsole 1; the lower surface of the wedge-shaped structure extends to the lower surface of the midsole 1, that is, the lower surface of the wedge-shaped structure constitutes a part of the lower surface of the forefoot portion of the midsole 1. The edge of the wedge-shaped structure is fitted and connected to the main body 12 of the forefoot portion, and the lower surface of the wedge-shaped structure is fitted and connected to the outsole 2. This arrangement enables the support portion 11 at the forefoot portion of the sole to fully play its supporting role, greatly enhancing the force feedback effect.

[0033] Of course, in addition to the above preferred arrangement, the thickness of the wedge-shaped structure (support portion 11) can also be adjusted according to different sports performance requirements. When the thickness of the wedge-shaped structure is less than the thickness of the forefoot portion of the midsole 1, the wedge-shaped structure can be wrapped inside the forefoot portion of the midsole 1, that is, the upper and lower surfaces of the wedge-shaped structure are wrapped by the main body 12 of the forefoot portion, or the wedge-shaped structure is located above or below the forefoot portion of the midsole 1, that is, the upper or lower surface of the wedge-shaped structure is wrapped by the main body 12.

[0034] In addition, when it is necessary to further enhance the supporting stability and force feedback effects of the support portion 11, the support portion 11 can also be arranged to protrude from the inner side wall or the outer side wall of the midsole 1, that is, the extension length of the bottom of the wedge-shaped structure is increased so that the bottom of the wedge-shaped structure extends to a position protruding from the side wall of the midsole 1.

[0035] The plane direction of the midsole 1 parallel to the ground is defined as the horizontal direction, and the direction from the inner side of the midsole 1 to the outer side or from the outer side to the inner side is defined as the lateral direction. Figure 4 As shown, the cross section of the support portion 11 in the horizontal direction of the midsole 1 is trapezoidal, the length of the upper bottom of the trapezoid is 41mm-61mm, the length of the lower bottom is 62mm-82mm, and the height is 18mm-28mm. During the badminton kicking process, the above arrangement can provide a stable support effect, and during the kicking process, it can provide faster kicking feedback and ankle joint stability.

[0036] Preferably, the support portion 11 is arranged corresponding to the first metatarsophalangeal joint and / or the fifth metatarsophalangeal joint of the human foot.

[0037] Further, if Figure 3 and Figure 4 As shown, the heel part of the midsole 1 is provided with a first groove 13, and an elastic block 3 is embedded in the first groove 13. The elastic block 3 is made of a first material, and the heel part of the midsole 1 is made of a second material. The resilience of the first material is better than the resilience of the second material. The elastic block 3 is light, soft and elastic, and can enhance the shock absorption and rebound effect of the heel part of the human body.

[0038] Further, if Figure 5 As shown, the outsole 2 is made of rubber material as a whole, including the forefoot area and the heel area. The inner side of the forefoot area is provided with a hollow hexagonal pattern structure 21, which can increase the sound during exercise and improve the anti-slip performance. Except for the inner side of the forefoot area, the rest of the area can be provided with a solid hexagonal pattern structure.

[0039] The forefoot region of the outsole 2 is also provided with a plurality of transverse curved grooves 22, and the middle portion of the forefoot region of the outsole 2 is provided with a longitudinal curved groove 23, which is connected to the plurality of transverse curved grooves 22. The cooperation between the transverse curved grooves 22 and the longitudinal curved grooves 23 can increase the movement flexibility of the sole of the foot, thereby improving the movement speed.

[0040] A plurality of horizontal stripe shading patterns 24 are arranged at the edge area of ​​the heel of the outsole 2. Since the stepping action mode of badminton is that the heel lands first and then transitions to the midfoot and forefoot, a plurality of horizontal stripe shading patterns 24 are arranged at the edge area of ​​the heel of the outsole 2, which is beneficial to improving the anti-slip performance of the heel landing on the ground on the one hand, and is beneficial to improving the wear resistance of the heel part on the other hand, and improving the overall stability.

[0041] To increase the wear resistance of the sole, the thickness of the inner side of the forefoot region and the outer side of the heel region of the outsole 2 are greater than the thickness of other regions of the outsole 2, and the other regions refer to all regions of the outsole 2 except the inner side of the forefoot region and the outer side of the heel region. Preferably, the thickness of the inner side of the forefoot region and the outer side of the heel region of the outsole 2 is increased by 0.5 mm compared with the thickness of other regions of the outsole 2.

[0042] Further, if Figure 4 As shown, a plurality of bending grooves 14 are arranged side by side at the forefoot of the midsole 1, and the bending grooves 14 extend in the transverse direction of the midsole 1, and at least one end of the bending groove 14 extends to the support portion 11. The bending grooves 14 are beneficial to improving the flexibility of the forefoot of the foot in badminton sports and improving the reaction speed of the action.

[0043] Further, if Figure 4 As shown, the upper surface of the midsole 1 at the midfoot portion is provided with a second groove 15, and the second groove 15 is embedded with a first support member 4. The lower surface of the midfoot portion of the midsole 1 is provided with a second support member 5. The first support member 4 is preferably a carbon plate made of carbon fiber material, and the second support member 5 is preferably a hard support plate made of TUP material. The first support member 4 and the second support member 5 work together, which is conducive to strengthening the anti-torsion performance of the foot, reducing sports injuries, and improving force feedback efficiency. The heel portion of the midsole 1 is provided with a heel stabilizer 6, which is preferably made of TPU hard material, so that the sole wraps the heel of the foot more closely and improves the stability of the heel.

[0044] The utility model also discloses a badminton shoe, comprising the above-mentioned sole capable of improving stability and ground pushing feedback.

[0046] 1. By setting a support part with higher density and hardness on the inner and / or outer side of the forefoot of the midsole, the sole can reduce the time of pushing off the ground, improve the movement speed and sports performance, and at the same time enhance the stable support in the lateral direction, providing faster pushing off feedback and foot joint stability during pushing off the ground.

[0047] 2. The forefoot part of the sole adopts a double-density structural design on the side and the middle, making the forefoot part of the sole light, soft and elastic, providing effective shock absorption and rebound effects for the human foot. Combined with the bending groove in the forefoot part, the bending flexibility of the sole is further improved.

[0048] 3. By setting an elastic block at the heel of the sole, it provides excellent shock absorption and rebound effects for the human heel. Combined with the heel stabilization component and the double-layer support structure, it improves the stability of the heel and midfoot area and prevents sports injuries caused by heel or midfoot instability during exercise.

[0049] 4. The pattern structure of the outsole can not only increase the sound during exercise, but also improve the anti-slip performance and stability during exercise, while also having good wear resistance.
