Description

Technical Field

[0001] This utility model relates to the field of footwear, and more particularly to a support member, as well as a sole and a shoe containing the support member. Background Technology

[0002] In sports like table tennis, tennis, and badminton, athletes utilize numerous lower limb techniques and tactical movements, such as movement and leaps, during daily training and competition. When athletes exert force, they use their lower limbs, waist, and shoulders to drive their arms and rackets. This often requires athletes to use tremendous force to push off the ground, resulting in significant impact on their lower limbs. Sports shoes are essential to control this impact. More specialized sports shoes not only enhance athletic performance but also prevent lower limb injuries during exercise, providing prevention and protection. Traditional sports shoes typically prioritize thinner soles to improve support and quick starts, focusing more on outsole traction and less on shock absorption and stability.

[0003] Therefore, shoes for sports such as table tennis, tennis, and badminton generally have a relatively thin sole structure and do not have a carbon fiber support component in the forefoot. Instead, they use hard materials to form the midsole. As a result, existing sports shoes cannot simultaneously provide stable support, quick start performance, and comfortable wearing feel. Utility Model Content

[0004] The purpose of this invention is to provide a support component, as well as a sole and shoe containing the support component. The asymmetrical, bifurcated structure support component, combined with a soft, elastic midsole, not only improves the stability of the sole during exercise and enhances rapid start-up performance, but also maintains a comfortable feel. The specific technical solution is as follows:

[0005] A support member includes a forefoot region, the forefoot region including a first bifurcation and a second bifurcation disposed opposite to each other, the first bifurcation and the second bifurcation being configured as arcs with opposite opening directions, the length of the first bifurcation being greater than the length of the second bifurcation, so as to enhance the support and flexibility of the forefoot region during the pedaling and turning phase.

[0006] Furthermore, it also includes the midfoot region, with the first bifurcation including a first connecting end and the second bifurcation including a second connecting end, the first connecting end being connected to the inner side of the midfoot region and the second connecting end being connected to the outer side of the midfoot region.

[0007] Furthermore, the first bifurcation portion also includes a first free end opposite to the first connecting end, and the second bifurcation portion also includes a second free end opposite to the second connecting end. The distance between the first free end and the midfoot region is greater than the distance between the second free end and the midfoot region.

[0008] Furthermore, the midfoot region is provided with a first reinforcing rib and a second reinforcing rib; and / or, the thickness of the midfoot region is greater than the thickness of the forefoot region.

[0012] A shoe sole includes the aforementioned support component and midsole. The midsole is made of foam material and includes a forefoot component and a midfoot component. The forefoot component is disposed corresponding to the forefoot area of ​​the support component, and the midfoot component is disposed corresponding to the midfoot area of ​​the support component. The distance between the forefoot component and the forefoot area on the side closer to the human foot is a first height, and the distance between the midfoot component and the midfoot area on the side closer to the human foot is a second height. The first height is greater than the first height.

[0013] Furthermore, the first height is 6mm to 8mm, the second height is 3mm to 5mm; and / or, the midsole also includes a heel component, the midsole hardness is 45 to 50 degrees, the height of the forefoot component is 6.5mm to 8.5mm, and the height of the heel component is 12mm to 15mm.

[0014] Furthermore, the first height is 7.2mm, the second height is 3.7mm; and / or, the midsole also includes a heel component, the midsole hardness is 47 degrees, the height of the forefoot component is 7.5mm, and the height of the heel component is 13.7mm.

[0015] Furthermore, the support component is located inside the midsole, and the support component and the midsole are designed as a single molded structure.

[0020] 1. By setting an asymmetrical arc structure with an inner length greater than the outer length in the forefoot area of ​​the support component, the support and flexibility of the forefoot area during the push-off and turning phase are enhanced, while improving the overall quick start performance of the shoe.

[0021] 2. The support component does not correspond to the entire sole of the human foot in the longitudinal direction, but extends slightly backward in the midfoot area.

[0022] 3. The outsole of the shoe has different tread patterns on the side facing the ground to enhance friction and speed up starting. Attached Figure Description

[0028] To better understand the purpose, structure, and function of this utility model, the support member, sole, and shoe of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 5 As shown, the support member 200 is disposed on the sole of the shoe. The support member 200 includes a forefoot area 210 and a midfoot area 220 connected together. The side of the sole body closer to the inside of the human foot is defined as the inner side of the sole body, the side of the sole body closer to the outside of the human foot is defined as the outer side of the sole body, the end of the sole body closer to the toe is defined as the front side of the sole body, and the end of the sole body closer to the heel is defined as the rear side of the sole body. The line connecting the inner and outer sides is transverse, and the line connecting the front and rear sides is longitudinal. The forefoot area 210 is provided with an asymmetrical arc structure with an inner length greater than the outer length, thereby enhancing the support and flexibility of the forefoot area 210 during the push-off and turning phase, while improving the overall quick start performance of the shoe.

[0030] Specifically, such as Figure 2 As shown, the forefoot region 210 of the support member 200 includes a first bifurcation 211 and a second bifurcation 212 arranged opposite to each other. The first bifurcation 211 is located near the inner side of the shoe body and is arranged along the inner arc, while the second bifurcation 212 is located near the outer side of the sole body and is arranged along the outer arc. Thus, the first bifurcation 211 and the second bifurcation 212 form an arc-shaped structure with opposite opening directions. This arc-shaped structure can provide additional lateral support during exercise, helping to reduce the risk of foot pronation and supination. Combined with the hollowed-out interval region 213 formed between the first bifurcation 211 and the second bifurcation 212, and after the forefoot region 210 is connected to the midfoot region 220, the forefoot region 210 has a ring structure with a forward opening. This structure can provide a more uniform pressure distribution when force is applied. When a person performs a pushing and turning action, the force is transmitted to the forefoot region 210 through the foot. These two bifurcations can effectively disperse the pressure on the inner and outer sides of the sole, reduce local stress concentration, and thus provide better support for the forefoot.

[0031] Both the first bifurcation 211 and the second bifurcation 212 are elongated, with the distance between their two ends defined as their length. The length of the first bifurcation 211 is greater than that of the second bifurcation 212. This structure allows the support member 200 to provide sufficient support while also adapting to the flexion requirements of the inner and outer sides of the foot. The longer first bifurcation 211 covers a larger area, providing stable support; while the shorter second bifurcation 212 allows for more space, enabling the forefoot to flex more naturally when necessary, thus improving overall flexibility. Furthermore, the interaction between the two bifurcations can be adjusted according to the actual needs of the foot during movement. For example, during the push-off and rotation, the shape and pressure distribution of the inner and outer sides of the foot will change. This structure allows the forefoot area 210 to better follow these changes, providing a faster response that fits the foot better, thereby improving athletic performance. The length of the first bifurcation 211 is 95mm to 100mm, and the length of the second bifurcation 212 is 70mm to 80mm. Preferably, the length of the first bifurcation 211 is 97.2mm, and the length of the second bifurcation 212 is 76mm, so that the first bifurcation 211 provides a stable support base, while the second bifurcation 212 ensures the flexibility and adaptability of the foot during the push-off and rotation phase, achieving a good balance between the two.

[0032] Furthermore, the support member 200 also includes a midfoot region 220. The first branch 211 includes a first connecting end disposed opposite to the first branch, and the second branch 212 includes a second connecting end. The first connecting end is connected to the inner side of the midfoot region 220, and the second connecting end is connected to the outer side of the midfoot region 220. Thus, the support member 200 can more effectively connect the forefoot region 210 and the midfoot region 220. In particular, by bringing the midfoot region 220 closer together, a more stable overall structure is formed. When exercising, especially when it is necessary to quickly change direction or start pushing off, this improved stability helps to reduce the risk of ankle sprains.

[0033] The first bifurcation 211 also includes a first free end 214 opposite to the first connecting end, and the second bifurcation 212 also includes a second free end 215 opposite to the second connecting end. The distance between the first free end 214 and the midfoot region 220 is greater than the distance between the second free end 215 and the midfoot region 220. That is, the line connecting the first connecting end of the first bifurcation 211 and the second connecting end of the second bifurcation 212 is basically perpendicular to the longitudinal direction of the support member 200. The first free end 214 of the first bifurcation 211 is closer to the front side of the sole body than the second free end 215 of the second bifurcation 212. This structure can provide better support and assistance to the first toe of the foot when performing a pedaling action, which helps to transmit the pressure on the inner side of the sole of the foot more directly to the ground, improves the pedaling efficiency, and makes each pedaling action more powerful and efficient.

[0034] Preferably, the midfoot region 220 is provided with a first reinforcing rib 221 and a second reinforcing rib 222. In this embodiment, one first reinforcing rib 221 and one second reinforcing rib 222 are each provided longitudinally and protrude towards the ground. The reinforcing ribs can increase the rigidity of the midfoot sole and prevent unnecessary twisting or deformation of the shoe during use. Combined with the structure of the forefoot region 210, it can maintain the natural shape of the foot and provide stable support, especially during high-intensity exercise. In addition, the design of the reinforcing ribs helps to more effectively transmit the pushing force from the forefoot to the ground, and at the same time, it can help to stably feed the reaction force back to the foot, making each step more powerful and efficient. This is particularly beneficial for sports that require fast movement, such as table tennis, tennis and badminton. The first reinforcing rib 221 and the second reinforcing rib 222 are located on the inner and outer sides of the midfoot region 220, respectively. The number of ribs can be adjusted according to different foot stress conditions, such as excessive inward or outward pronation, to meet the needs of different users and provide more personalized support and protection.

[0035] Preferably, the thickness of the midfoot region 220 is greater than the thickness of the forefoot region 210. This structural design is because the midfoot region 220 bears most of the pressure of the entire body weight and plays a key supporting role during exercise. Increasing the thickness of the midfoot region 220 can provide additional support and help maintain the natural shape of the arch of the foot. At the same time, reducing the thickness of the forefoot region 210 enhances forefoot support and provides good flexion flexibility, improving comfort and extension / flexion effects during exercise. The thickness of the forefoot region 210 is 0.7mm to 1.1mm, and the thickness of the midfoot region 220 is 1.0mm to 1.4mm. In this embodiment, the thickness of the forefoot region 210 is 0.9mm, and the thickness of the midfoot region 220 is 1.2mm, so that movements requiring precise forefoot control are not too stiff, providing good tactile feedback and control.

[0036] like Figure 3 As shown, the midfoot region 220 corresponds to the arch of the human foot and the side of the heel closest to the arch. The first bifurcation 211 corresponds to the inner side of the forefoot, and the second bifurcation 212 corresponds to the outer side of the forefoot. The interval 213 between the first bifurcation 211 and the second bifurcation 212 corresponds to the second, third, and fourth metatarsal bones of the human foot, allowing the forefoot region 210 to flex and extend flexibly in the corresponding positions. It can be understood that the support member 200 of this utility model does not correspond to the entire sole of the human foot in the longitudinal direction, but extends slightly backward in the midfoot region 220. This can provide effective support for the forefoot and midfoot without affecting the shock absorption performance of the heel, and can increase the comfort and fit of the foot when wearing the shoe.

[0037] Furthermore, the width of the first bifurcation 211 is 10mm to 15mm, and the width of the midfoot region 220 is 30mm to 40mm. In this embodiment, the width of the first bifurcation 211 is 13mm, and the width of the midfoot region 220 is 35mm. This parameter setting provides necessary support for the arch and inner and outer sides of the forefoot without reducing comfort. The wider midfoot region 220 increases the fit when wearing the garment, while the narrower width of the first bifurcation 211 and the second bifurcation 212 ensures the freedom of movement of the forefoot and improves overall comfort.

[0038] like Figure 1 As shown, this utility model also provides a shoe sole, including the aforementioned support member 200 and midsole 100. The midsole 100 is made of foam material, which has the characteristics of being lightweight, soft and elastic. The midsole 100 includes a forefoot component 101, a midfoot component 102 and a heel component 103 arranged in sequence. After being layered and composited with the support member 200, it can enhance the structural stability while ensuring the softness and comfort of the shoe sole. The rigid support provided by the support member 200 is combined with the flexibility of the foam material, which ensures sufficient support without sacrificing flexibility.

[0039] Specifically, the forefoot component 101 of the midsole 100 is correspondingly set with the forefoot area 210 of the support member 200, and the midfoot component 102 is correspondingly set with the midfoot area 220 of the support member 200. The direction perpendicular to the support plate is defined as the vertical direction, and the distance between the midsole 100 and the support member 200 in the vertical direction is defined as the height. The distance between the forefoot component 101 near the human foot and the forefoot area 210 is the first height, and the distance between the midfoot component near the human foot and the midfoot area 220 is the second height. The first height is greater than the first height, that is, the distance between the forefoot area 210 of the support member 200 and the human foot is greater than the distance between the midfoot area 220 of the support member 200 and the human foot.

[0040] The purpose of this structure is that, in this embodiment, the first height is relatively large, that is, the thickness of the midsole 100 between the support member 200 and the foot is increased. This can improve the forefoot bending stiffness and starting speed while also improving forefoot comfort. In other words, if the support member 200 is too close to the foot, the forefoot will feel uncomfortable during the push-off or extension process. The second height is relatively small, which can enhance the anti-torsion performance of the midfoot.

[0041] The first height is 6mm to 8mm, and the second height is 3mm to 5mm. Preferably, the first height is 7.2mm and the second height is 3.7mm. The first height can provide more cushioning space for the forefoot, and the second height provides closer support in the midfoot area 220. This helps maintain the natural shape of the foot, ensures the necessary stability and control in the midfoot position, and avoids instability caused by excessive cushioning.

[0042] Furthermore, the midsole 100 has a hardness of 45 to 50 degrees, the forefoot component 101 has a height of 6.5 mm to 8.5 mm, and the heel component 103 has a height of 12 mm to 15 mm. Preferably, the midsole 100 has a hardness of 47 degrees, giving it moderate softness and resilience, providing good cushioning while ensuring a certain level of support, which helps reduce fatigue during long-term exercise. The forefoot component 101 has a height of 7.5 mm, which ensures sufficient flexibility and ground awareness, making the forefoot more natural and efficient during push-off and rotation. The heel component 103 has a height of 13.7 mm, which provides more cushioning and absorbs additional cushioning pressure, effectively reducing the impact on the knees and hip joints.

[0043] Preferably, the support member 200 is disposed inside the midsole 100, and the support member 200 and the midsole 100 are integrally molded to ensure that there is no relative movement between the support member 200 and the midsole 100, thereby providing more stable support. In addition, both ground reaction force and pedaling force can be transmitted with minimal energy loss, which can effectively improve athletic performance.

[0044] Preferred, such as Figure 1 and Figure 4 As shown, the sole also includes an outsole 300, which is located below the midsole 100 and directly contacts the ground. The outsole 300 includes a forefoot portion 310, a midfoot portion 320, and a heel portion 330. The forefoot portion 310 corresponds to the forefoot component 101 of the midsole 100, the midfoot portion 320 corresponds to the midfoot component 102 of the midsole 100, and the heel portion 330 corresponds to the heel component 103 of the midsole 100. Different outsole patterns are provided on the side of the outsole 300 facing the ground to enhance friction and improve quick start. In this embodiment, as a preferred solution, all of the following patterns are provided to achieve the best effect.

[0045] Specifically, the inner side of the forefoot portion 310 features several multi-directionally extending first treads 311, providing friction in different directions. This enhances the shoe's grip, providing better ground adhesion for straight-line movement, lateral movement, and sudden stops and turns, thus improving agility during push-off and rotation. The outer and front sides of the forefoot portion 310 feature several wavy second treads 312. The second treads 312 extend longitudinally on the outer side of the forefoot portion 310 and laterally on the front side, with a linear transition in the middle. This increases the friction area between the sole and the ground, providing additional grip, particularly in the longitudinal direction, and offering flexible bending in the lateral direction. This is especially important for actions requiring rapid lateral movement or sudden stops, effectively preventing slippage and improving athletic performance. A wavy dividing channel 313 separates the first treads 311 and the second treads 312. A circular third tread pattern 314 is located in the middle of the inner side of the forefoot 310. This helps to distribute pressure more evenly in this area, avoiding discomfort or injury caused by excessive local pressure. The circular pattern guides the force to be dispersed in all directions, helping to reduce the burden on the first and second metatarsophalangeal joints of the foot. Several wavy fourth tread patterns 321 extend laterally along the midfoot 320 and the side of 330 closest to the midfoot 320. This helps to improve the stability of the sole during forward and backward movement. For sports requiring frequent forward and backward movement or quick changes of direction, the lateral wavy pattern provides additional grip and support, helping the body maintain balance. Several straight fifth tread patterns 331 extend laterally along the side of 330 away from the midfoot 320. The laterally arranged straight fifth tread patterns 331 increase the friction area when the sole contacts the ground, providing additional grip, especially in the forward and backward directions.

[0046] It is understood that the longitudinal or transverse extension direction of the above-mentioned texture includes both completely perpendicular longitudinal or transverse directions in the horizontal direction and longitudinal or transverse extensions with a slight deflection angle, as long as it can achieve the effect of increasing friction and grip.

[0047] Furthermore, such as Figure 5 As shown, the inner side of the forefoot 310 extends toward the human foot to form a wear-resistant part 315. The wear-resistant part 315 is provided with a first tread 311. Since the foot often protrudes during sports such as table tennis, tennis, and badminton, the inner side of the shoe is often in contact with the ground. The wear-resistant part 315 can increase the anti-slip performance of the inner edge to a certain extent, and also increase the wear resistance of the edge.

[0048] A quadrilateral hollow area 322 is provided in the middle of the midfoot portion 320 of the outsole 300. This hollow area 322 corresponds to the midfoot portion 220 of the support member 200. That is, there is no midsole 100 between the hollow area 322 and the support member 200. The structure of the support member 200 can be displayed through this hollow area 322. At the same time, the outsole 300 is located in the mid-waist position and does not directly contact the ground. Therefore, the weight of the shoe can be reduced through the hollow area 322 without affecting the overall structural strength and durability of the shoe sole.

[0049] Preferably, the first tread pattern 311 is a Y-shaped outsole pattern. The Y-shaped pattern design provides additional friction in multiple directions, which helps enhance the shoe's grip in different sports modes, especially important when performing complex movements such as sudden stops, sharp turns, or rapid changes of direction. This helps the body better control its stride and distributes the pressure applied to the inner forefoot more evenly. In addition, the Y-shaped pattern helps avoid discomfort or potential injury caused by excessive local pressure, especially in high-intensity sports such as table tennis, tennis, and badminton.

[0050] This utility model also provides a shoe, including the support member 200 described above, or including the sole and upper described above.

[0051] Shoes equipped with the aforementioned support components were used as experimental examples, while shoes without such support components were used as control examples for comparative testing. Mechanical test results showed that, compared to the control examples, the forefoot flexural stiffness of the experimental examples increased by 123%, internal torsion by 94%, and external torsion by 90%. Combining biomechanical data, mechanical data, and subjective feedback results, the sole stability of the experimental examples increased by 44.4% and the rapid start performance increased by 7% compared to the control examples. This demonstrates that the experimental examples provided by this invention outperform the control examples in terms of shoe stability and rapid start performance.

[0052] The support member of this utility model, as well as the sole and shoe containing the support member, have the following advantages:

[0053] 1. By setting an asymmetrical arc structure with an inner length greater than the outer length in the forefoot area of ​​the support component, the support and flexibility of the forefoot area during the push-off and turning phase are enhanced, while improving the overall quick start performance of the shoe.

[0054] 2. The support component does not correspond to the entire sole of the human foot in the longitudinal direction, but extends slightly backward in the midfoot area. This can provide effective support for the forefoot and midfoot without affecting the shock absorption performance of the heel, and can increase the comfort and fit of the foot when wearing the shoe.

[0055] 3. The outsole of the shoe has different tread patterns on the side facing the ground to enhance friction and speed up starting.
