Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a sole with rebound propulsion force, a supporting piece and a shoe. Background Art

[0002] Basketball shoes are crucial for players. They not only protect joints like ankles and knees, reducing injury risk, but also enhance performance and comfort through superior grip, cushioning, and support. The right basketball shoes help players maintain confidence and focus during games, meeting the individual needs of players in different positions, allowing them to perform at their best on the court.

[0003] The midsole of basketball shoes directly impacts comfort, stability, and performance. Players require good cushioning to absorb the impact of jumping and stopping suddenly, protecting joints from injury. At the same time, the midsole must also provide adequate support to stabilize the arch and ankle and prevent sprains. Furthermore, a highly elastic and responsive midsole helps players quickly convert power on the court and enhance explosive power. Durability is also key, ensuring that the midsole maintains its performance despite frequent use and resists deformation or damage. A lightweight design helps reduce foot strain, enhancing speed and agility, while moderate flexibility provides comfort and freedom of movement while maintaining support. These functional requirements work together to ensure players maintain optimal performance during competition and reduce the risk of injury.

[0004] In addition, the number of marathon events has increased year by year, and the number of people participating in marathons has also increased significantly. While runners participating in full marathons and half marathons are concerned about improving their performance, they also have higher requirements for comfort in the second half of the race or after completing the race.

[0005] Compared to other sports, running is a highly repetitive activity for regular or professional runners. During the ground contact phase, runners wearing professional racing shoes need to not only reduce ground impact but also provide rapid rebound, transition forward, and efficiently push off the ground, completing the entire landing phase of the gait. Integrating the gait and force characteristics of professional runners with a composite sole structure, and balancing performance and comfort, comprehensive running shoes are a key research direction in the development of sports shoes. However, most of the existing shoe technology solutions mentioned above have the following problems:

[0006] (1) The current midsole structure is mainly composed of foam materials of various hardness and shapes, with support plates used as auxiliary to improve the stability of the sole. Most racing running shoes have thick-soled structures. Studies have shown that wearing thick-soled carbon plate racing running shoes has poor overall dynamic stability when jumping forward with one leg, and poor dynamic stability in the left and right directions when jumping sideways with one leg, which may bring certain risks of injury during exercise.

[0007] (2) In the second half of a full marathon, the runner's landing pattern will change continuously, from forefoot and midfoot landing to heel landing, and the transition from heel landing to midfoot landing requires higher heel rebound and shock absorption to compensate for the decrease in muscle strength caused by lower limb and foot muscle fatigue in the second half of the marathon. Rapid braking and providing a strong rebound effect are crucial for elite runners to improve their performance.

[0008] (3) Most racing running shoes are designed for runners who land on their heels. However, studies have found that compared with running in cushioned shoes or heel strike, the peak force of the Achilles tendon increases significantly when running in five-finger shoes or forefoot strike, and more Achilles tendon work can be generated during the extension phase. That is, the landing mode needs to be converted to the forefoot, thereby providing a higher load intensity to improve the mechanical characteristics of the Achilles tendon.

[0009] (4) In the second half of the full marathon, the forefoot will become hot and hard, which will obviously affect the subjective comfort. Utility Model Content

[0042] In order to better understand the purpose, structure and function of the present invention, the sole, support member and shoe with rebound propulsion force of the present invention are described in detail below with reference to the accompanying drawings.

[0043] like Figure 1 As shown, the sole with rebound propulsion includes a support member 100, a second elastic layer 400 and a support plate 200. The support member 100 includes a forefoot area 110, a midfoot area 120, and a heel area 130 connected in sequence. The side of the support member close to the inner side of the human foot is defined as the inner side of the support member, the side of the support member close to the outer side of the human foot is defined as the outer side of the support member, the end close to the toe of the human foot is defined as the front side of the support member, and the end close to the heel of the human foot is defined as the back side of the support member. The first area of the second elastic layer corresponds to the forefoot area 110 of the support member 100, and the support member 100 and the first area of the second elastic layer enclose a hollow structure 140.

[0044] The hollow structure 140 can undergo elastic deformation when the forefoot of the sole is under pressure. The hollow structure 140 preferably crosses the inner and outer sides of the support member, so that the inner and outer sides of the sole body are interconnected. The hollow structure 140 can also be a hollow structure arranged inside the sole body. The hollow structure 140 is preferably a complete arched or oblate circular structure, or it can be two or more hollow structures concentrated in the forefoot area of the sole body. The hollow structure 140 is provided in the forefoot area 110. The compression deformation of the hollow structure 140 helps to adjust the running posture when landing, guides the landing transition to the middle forefoot, reduces the pressure on the dorsum of the foot and the tibialis anterior muscle on the front of the calf when landing, thereby increasing the shock absorption and rebound performance, and providing better protection and assistance to the wearer.

[0045] In addition, the forefoot area 110 of the support member extends to the heel area 130. Therefore, when the hollow structure 140 located in the forefoot area 110 is compressed and deformed, as the hollow structure 140 begins to recover its original shape, the elastic potential energy stored at this time will be released. This part of the released energy will be transferred to the heel area 130 in the form of elastic potential energy, thereby providing strong rebound potential energy to the heel area 130, making the transition from braking to extension smoother and more efficient. In addition, the support plate 200 with different structural characteristics on the inner and outer sides of the forefoot is designed according to the force characteristics in the left and right directions during the extension stage, which can better provide extension support and propulsion effects.

[0046] In summary, the sole with rebound propulsion in the present invention adopts a composite setting of double-layer support and elastic layer, and the forefoot part of the support is also provided with a hollow structure 140. This composite setting method helps to adjust the landing posture and guide the human foot to land in the middle and forefoot. At the same time, the support part and the hollow structure 140 undergo buffering deformation, which stores elastic potential energy and transfers it to the heel area 130 for release. In this process, the sole as a whole will produce a linkage force feedback mechanism, which recovers the energy generated when the wearer's forefoot lands, and releases a large amount of rebound energy to the heel area 130 of the human foot, thereby enhancing the propulsion force of the sole.

[0047] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the sole, support member and shoe with rebound thrust in accordance with the present invention, taking the specific structure of the support member with rebound thrust as an example in conjunction with the accompanying drawings.

[0048] like Figures 1 to 4 As shown, the sole with rebound propulsion force includes a support member 100, a second elastic layer 400 and a support sheet 200 arranged in sequence from top to bottom. The support member 100 includes a forefoot area 110, a midfoot area 120 and a heel area 130. The second elastic layer 400 includes a first area, a second area, and a third area, which respectively correspond to the forefoot area 110, the midfoot area 120 and the heel area 130 of the support member 100. The support sheet 200 is arranged opposite to the forefoot area 110, and the support member 100 is extended inward and outward. The upper part is arched to form a hollow structure 140 between the forefoot area 110 of the support member 100 and the first area of the second elastic layer 400. The hollow structure 140 can make the support member elastically deform in the forefoot area 110, thereby transferring the elastic potential energy to the heel area 130 of the support member 100 through the midfoot area 120 to provide rebound potential energy. In addition, the penetrating setting of the hollow structure 140 also facilitates gas flow, improves the heating caused by repeated impact force in the forefoot area 110, and enhances the comfort of the human foot.

[0049] Specifically, the support member as a whole is arranged in a front fork structure that is wide in front and narrow in the back. The lateral width between the inner and outer sides of the forefoot area 110 is the largest, and the width gradually decreases from front to back to the heel area 130. Taking size US9 as an example, the heel width is 88mm, which is smaller than its usual width design. By reducing the area of the heel area 130 and narrowing the bottom heel width combined with the rebound characteristics of the hollow structure 140 of the forefoot area 110 of the support member 100, the landing mode can be guided to transition to the mid-forefoot landing, giving play to the advantages of the running posture of the forefoot landing mode, and improving sports performance through the linkage force feedback mechanism, which is more conducive to improving the sports performance of top athletes.

[0050] The forefoot region 110 of the support member 100 includes a first bifurcated structure 111 and a second bifurcated structure 112. The first bifurcated structure 111 is located on the inner side of the forefoot region 110, while the second bifurcated structure 112 is located on the outer side of the forefoot region 110. This forms a hollow groove structure that opens forward between the first bifurcated structure 111 and the second bifurcated structure 112. Because pressure distribution in the forefoot region 110 is uneven during the extension phase, primarily at the first metatarsophalangeal joint, the groove structure formed by the bifurcated structure reduces the lateral rigidity of the forefoot region 110, thereby reducing excessive restriction of the support member 100 on the forefoot region 110 of the human foot and enhancing the foot's flexibility during movement.

[0051] Preferably, the first forked structure 111 and the second forked structure 112 are arranged according to the shape of the toes of the human foot. The length of the first forked structure 111 is greater than the length of the second forked structure 112 and is closer to the toe position. Specifically, the first forked structure 111 in the forefoot area 110 corresponds to the first phalanx of the human foot, the groove structure corresponds to the second phalanx of the human foot, and the second forked structure 112 corresponds to the third phalanx, fourth phalanx, and fifth phalanx of the human foot. The above corresponding position settings are more conducive to the release of forefoot flexibility.

[0052] Furthermore, the first forked structure 111 and the second forked structure 112 are arched upward in the front-to-back direction to form an arc-shaped first concave structure and a second concave structure, respectively. The first forked structure is an integrally formed structure, and the second forked structure is an integrally formed structure to enhance the strength of the first concave structure and the second concave structure and improve the stability of the first forked structure and the second forked structure.

[0053] The support sheet 200 is disposed below the support member 100. The first concave structure and the inner side of the first region of the second elastic layer 400 enclose a first hollow structure 140. The second concave structure and the outer side of the first region of the second elastic layer 400 enclose a second hollow structure 140. The support sheet 200 may have a certain downward curvature, so that the lateral cross-section of the hollow structure 140 forms an oblate structure. Of course, the support sheet 200 may also be configured as a horizontal structure, in which case the lateral cross-section of the hollow structure 140 forms an arched structure. In other words, as long as the support sheet 200 encloses the forefoot region 110 of the support member 100 to form a deformable hollow structure 140, a propulsion effect on the heel region 130 of the support member 100 can be achieved.

[0054] Specifically, such as Figure 3As shown, the first hollow structure 140 and the second hollow structure 140 are horizontally connected from the inside to the outside, that is, they are arranged horizontally, and the through channel formed corresponds to the metatarsophalangeal joint of the human foot. The setting position corresponds to the metatarsophalangeal joint as the key force-bearing area of the human foot during the mid-forefoot landing and extension stages. The hollow structure 140 is squeezed downward through the metatarsophalangeal joint to deform and store elastic potential energy. As the foot rolls, the pressure is gradually transmitted from the forefoot area 110 to the heel area 130. At this time, the previously compressed hollow structure 140 begins to restore its original shape, and in this process, the previously stored elastic potential energy is released, thereby generating an upward thrust through the support member 100. This rebound can provide a linked rebound potential energy to the heel area 130, and can also reduce the impact when the heel lands.

[0055] In this embodiment, the lengths of the first and second upward concave structures are 50 mm to 70 mm, corresponding to the area around the metatarsophalangeal joints of the human foot, so that the deformation of the hollow structure 140 reaches an optimal range.

[0056] like Figure 6 As shown, the support sheet 200 is two independent sheet-like structures, which are approximately trapezoidal in shape as a whole, including a first support sheet 201 and a second support sheet 202 arranged at intervals. The first support sheet 201 is located on the inner side of the sole, and the first support sheet 201 is arranged corresponding to the first upper concave structure of the support member 100. The first support sheet 201 is located on the outer side of the sole, and the second support sheet 202 is arranged corresponding to the second upper concave structure of the support member 100. The interval 203 between the first support sheet 201 and the second support sheet 202 corresponds to the groove structure of the support member 100, so as to reduce the excessive restriction of the support sheet 200 on the forefoot area 110 of the human foot and enhance the flexibility of the foot during movement.

[0057] Furthermore, the first support plate 201 and the second support plate 202 are arranged according to the shape of the human foot. The first support plate 201 corresponds to the first metatarsophalangeal joint of the human foot, and the second support plate 202 corresponds to the third metatarsophalangeal joint, the fourth metatarsophalangeal joint, and the fifth metatarsophalangeal joint of the human foot. The first support plate 201 is closer to the front side of the human foot than the second support plate 202, which helps to support the key force of the forefoot area 110, so that the hollow structure 140 is fully compressed, thereby providing a strong rebound effect. At the same time, according to the force characteristics in the left and right directions during the extension phase, support plates at different positions and structures on the inner and outer sides of the forefoot are arranged to form different hollow structures 140, which can better provide extension support and propulsion effects.

[0058] Further, such as Figure 4 and Figure 5As shown, the support member 100 also includes a first upward-turned structure 113 and a second upward-turned structure 121. The first upward-turned structure 113 extends upward along the outer sides of the forefoot region 110 and the midfoot region 120, forming a structure that gradually narrows from bottom to top. This reduces the risk of excessive displacement of the foot within the shoe during high-intensity lateral movements, leading to rollover or sprains, and enhances the anti-rollover effect of the sole. The first upward-turned structure 113 corresponds to the outer side of the fifth metatarsophalangeal joint of the human foot, has a length of 10mm to 20mm, a height of 10mm to 18mm, and an inclination angle of 60 degrees to 80 degrees. This specific setting position and parameters correspond to the main stress point on the outer side of the forefoot region 110 of the foot, and forms a covering shape for this stress point area, tightening the muscles and joints in this area to enhance the protection effect.

[0059] The second upward-turned structure 121 extends upward along the medial side of the midfoot region 120, forming a structure that gradually narrows from bottom to top. This supports the arch of the foot and helps stabilize the foot, especially during rapid changes of direction, sudden stops, and jumps. It reduces the risk of excessive inversion or eversion of the foot, preventing sprains and other foot injuries. The second upward-turned structure 121 corresponds to the medial side of the navicular bone of the human medial longitudinal arch. It has a height of 3mm to 7mm, a length of 40mm to 60mm, and an inclination angle of 6 degrees to 20 degrees. This specific location and parameters correspond to the medial arch stress point of the midfoot region 120, and forms a covering shape around this stress point, tightening the muscles and joints in this area to enhance the protective effect.

[0060] Furthermore, a circular hollow structure 131 is provided in the heel area 130 of the support member 100. The provision of the hollow structure 131 can optimize the structure of the heel area 130 of the support member 100, so that it can reduce the weight while still maintaining sufficient stability, preventing unnecessary displacement or flipping of the heel during exercise, and at the same time giving full play to the shock-absorbing performance of the elastic layer above and / or below it.

[0061] The above-mentioned composite setting method allows the second elastic layer 400 and the hollow structure 140 to undergo buffering deformation simultaneously when the sole touches the ground. At the same time, the support members and support plates in the sole will rebound quickly to restore the sole to its original shape and promote the deformed hollow structure 140 to quickly restore its shape. In this process, the energy generated by the wearer's each step when landing is recovered through the rebound force feedback mechanism linked between the forefoot area 110 and the heel area 130, and a large amount of rebound energy is released to the heel area 130 of the human foot, thereby enhancing the propulsion force of the sole.

[0062] Furthermore, the sole also includes a first elastic layer 300, which is arranged above the support member 100 to form an integral structure, so as to facilitate the production process, provide a better and more comfortable foot feel and force feedback, and achieve the effect of promoting the linkage rebound force feedback mechanism of the forefoot area 110.

[0063] Preferably, a transversely penetrating concave structure is formed in the first area, and the first upper concave structure and the second upper concave structure of the support member 100 correspond to the upper part of the concave structure, and the lower part of the concave structure corresponds to the support sheet 200, so as to increase the height of the first hollow structure and the second hollow structure, thereby achieving the effect of enhancing the elasticity of the hollow structure 140.

[0064] The material of the above-mentioned support members and support sheets is characterized by a Shore D hardness of 50-95, and the support plates are made of other hard materials, such as at least one of phenolic resins or thermoplastic resins (thermoplastic polyurethane, polycarbonate, polymethyl methacrylate, nylon elastomer, polyether ester elastomer, polyketone, polyether ether ketone, polyether ketone ketone, polyether sulfone, polyphenylene sulfide, ABS (acrylonitrile-butadiene-styrene copolymer) or a composite material formed with inorganic fillers or long fibers or short fibers (not limited to carbon fiber, glass fiber, aramid, ultra-high molecular weight polyethylene fiber, polyarylate fiber, basalt fiber, polyester fiber, etc.).

[0065] The elastic layer is made of one, two or more of the following materials: nylon elastomer, polyurethane (thermoplastic polyurethane (including aromatic and aliphatic types), cast polyurethane, and mixed polyurethane), thermoplastic polyetherester elastomer, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer, high styrene rubber, brominated butyl rubber, butadiene rubber, silicone rubber, EPDM rubber, natural rubber, isoprene rubber, nitrile rubber, and chloroprene rubber, through supercritical foaming or chemical foaming molding processes. It is characterized by a hardness of 40-45°C and a density of 0.12-0.18 g / cm 3 The material is lightweight, soft, and flexible, providing excellent shock absorption and rebound during movement from the midfoot to the forefoot. The elastic layer conforms to the shape of the support member and support plate.

[0066] The outsole 500 includes an outsole 500 disposed below the support plate 200. The outsole 500 is formulated using a rational formula to produce a material that exhibits both excellent anti-slip properties and fatigue wear resistance. Using the thinnest thickness possible, the outsole 500 can meet the demands of running, effectively reducing the thickness and weight of the sole, achieving the lightweight design goal, and providing the wearer with a better wearing experience. The outsole 500 is made of one or more of the following: styrene-butadiene rubber, bromobutyl rubber, butadiene rubber, silicone rubber, EPDM rubber, natural rubber, isoprene rubber, nitrile rubber, chloroprene rubber, nylon elastomer, polyurethane (thermoplastic polyurethane (including aromatic and aliphatic types), cast polyurethane, and mixed polyurethane), thermoplastic polyetherester elastomer, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer, and high styrene rubber.

[0067] In order to provide the best force feedback performance with the support plate, we use nylon elastomer material in the first elastic layer 300 and the second elastic layer 400, with a density of 0.12-0.14g / cm 3 , Shore C hardness is 42±3, rebound rate (Energy return) is 80%, peak acceleration (Peak G) is 10.1; providing light + high elastic effect. Support member 100 and support sheet 200 are hard support plates, made of carbon fiber / glass fiber / epoxy resin composite material, each layer is 0.12mm thick, with a total thickness of 1.0-1.6mm.
