Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear and apparel technology, specifically to an irregularly shaped anti-torsion plate and a sports shoe with the anti-torsion plate. Background Technology
[0002] An anti-torsion plate is a device used to enhance the torsional resistance of a structure. It is mainly used in fields such as athletic shoe design. Its core function is to prevent excessive deformation and improve stability. An anti-torsion plate is usually a plate-shaped device installed in the arch area of the midsole of an athletic shoe. By limiting excessive torsion of the sole during exercise, it disperses the force on the foot, thereby reducing the risk of injury to the plantar fascia and other parts. It can also effectively limit the torsion phenomenon generated by the athletic shoe during exercise, reducing the risk of ankle sprains.
[0003] While the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: existing anti-torsion plates are usually long strip-shaped structures embedded in the midsole. Although they can provide anti-torsion performance for athletic shoes, when wearing athletic shoes for intense lateral movement, there will be a certain angle between the foot and the ground, and the arch of the foot will be compressed downward by downward pressure. The anti-torsion plate cannot effectively support the arch, which can easily lead to arch fatigue. Moreover, when making lateral movements, if the wearer applies a large lateral force, the lateral torque on the athletic shoe will increase significantly. When subjected to excessive torque, the long strip-shaped anti-torsion plate often cannot provide sufficient anti-torsion capacity and is prone to deformation, thus affecting the anti-torsion effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a non-circular anti-torsion plate with high torsional strength and good arch support, as well as a sports shoe with the anti-torsion plate.

[0006] A further improvement is that a front extension plate is integrally formed on the edge of the anti-torsion plate body facing the forefoot of the human foot.
[0007] A further improvement is that a rear extension plate is integrally formed on the edge of the anti-torsion plate body facing the heel of the human foot.
[0008] A further improvement is that the stabilizing structure includes a first inclined plate integrally formed at the center of the anti-torsion plate body and a second inclined plate integrally formed at the center of the anti-torsion plate body. The stabilizing structure also includes a third inclined plate integrally formed at the center of the anti-torsion plate body. The edges of the first inclined plate, the second inclined plate and the third inclined plate converge and combine to form a triangular pyramidal convex cavity.
[0009] A further improvement is that the anti-torsion plate body is integrally formed with reinforcing ribs surrounding the edge of the stable structure at the bottom edge of the stable structure.
[0010] A further improvement is that the third inclined plate has an integrally formed pressure-reducing groove.
[0011] To achieve the above objectives, the present invention may also adopt the following technical solution: a sports shoe, including a midsole and an outsole fixed to the bottom surface of the midsole, wherein an upper body is fixedly provided on the midsole, the upper body has an opening at the heel position of the human foot, and an anti-torsion plate is embedded in the middle section of the bottom surface of the midsole.
[0012] A further improvement is that the anti-torsion plate includes an anti-torsion plate body, the center of which is integrally formed with a stable structure, and the anti-torsion plate body is also integrally formed with an upper support plate on the side corresponding to the arch of the human foot.
[0013] A further improvement is that a front extension plate is integrally formed on the edge of the anti-torsion plate body facing the forefoot of the human foot.
[0014] A further improvement is that a rear extension plate is integrally formed on the edge of the anti-torsion plate body facing the heel of the human foot.
[0015] A further improvement is that the stabilizing structure includes a first inclined plate integrally formed at the center of the anti-torsion plate body and a second inclined plate integrally formed at the center of the anti-torsion plate body. The stabilizing structure also includes a third inclined plate integrally formed at the center of the anti-torsion plate body. The edges of the first inclined plate, the second inclined plate and the third inclined plate converge and combine to form a triangular pyramidal convex cavity.
[0016] A further improvement is that the anti-torsion plate body is integrally formed with reinforcing ribs surrounding the edge of the stable structure at the bottom edge of the stable structure.
[0017] A further improvement is that the third inclined plate has an integrally formed pressure-reducing groove.
[0018] A further improvement is that a tongue extending towards the toe is sewn onto the upper at the entrance.
[0019] A further improvement is that the upper body is also fitted with shoelaces above the tongue.
[0020] After adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0021] 1. This utility model has an upper support plate integrally formed on the side of the anti-torsion plate body corresponding to the human arch of the foot. After being installed in sports shoes, the upper support plate can provide upward support for the human arch of the foot. When wearing sports shoes for intense lateral movement, it can provide good support for the arch of the foot, so that the arch of the foot will not overstretch during exercise, thereby avoiding rapid fatigue of the arch of the foot and providing good wearing comfort.
[0022] 2. When the anti-torsion plate is subjected to torsional force during lateral pushing off the ground while wearing this utility model, the torsional force on the anti-torsion plate body can be resisted by the stabilizing structure. Since the stabilizing structure is composed of a first inclined plate, a second inclined plate, and a third inclined plate, and extends upward to form a triangular pyramid structure, it can provide high stability and is not easy to deform when subjected to torsional forces from the front and back through the triangular structure of the front section. When subjected to lateral torsional forces, its side also forms a stable triangular structure and is not easy to deform. This greatly improves the torsional resistance of the anti-torsion plate, making the anti-torsion plate less prone to deformation and more stable. Attached Figure Description

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0030] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: an irregularly shaped anti-torsion plate, including an anti-torsion plate body 11, with a stabilizing structure 26 integrally formed at the center of the anti-torsion plate body 11. The stabilizing structure 26 includes a first inclined plate 21 integrally formed at the center of the anti-torsion plate body 11 and a second inclined plate 22 integrally formed at the center of the anti-torsion plate body 11. The stabilizing structure 26 also includes a third inclined plate 23 integrally formed at the center of the anti-torsion plate body 11. The edges of the first inclined plate 21, the second inclined plate 22, and the third inclined plate 23 converge. The anti-torsion plate body 11, located on the side corresponding to the arch of the foot, is integrally formed with an upper support plate 51, forming a triangular pyramid-shaped convex cavity. During use, the anti-torsion plate is molded using a mold. The anti-torsion plate body 11 can be made of TPU or carbon fiber. The anti-torsion plate body 11 provides anti-torsion capabilities. When installed in the midsole of a shoe, if subjected to a relatively slight torsional force, the strength of the anti-torsion plate body 11 itself can offset and absorb the torsional force. The anti-torsion plate body 11 is integrally formed on the side corresponding to the arch of the foot. The upper support plate 51, after being installed inside the sports shoe, provides upward support to the arch of the foot. During intense lateral movement while wearing the sports shoe, it provides good support for the arch, preventing overextension and thus avoiding rapid fatigue. It also provides good comfort. Furthermore, when the anti-torsion plate body 11 is subjected to torsional force due to high-intensity lateral push-off during wear, the stabilizing structure 26 can resist the torsional force. The stabilizing structure 26 is composed of a first inclined plate 21, a second inclined plate 22, and a third inclined plate 23, extending upward to form a triangular pyramid structure. When subjected to torsional forces from the front and rear, the triangular structure of the triangular pyramid formed by the three inclined plates provides high stability and is not prone to deformation. When subjected to lateral torsional forces, the sides of the triangular pyramid formed by the three inclined plates also form a stable triangular structure, which is not prone to deformation. This significantly improves the torsional resistance of the anti-torsion plate, making it less prone to deformation and more stable.
[0031] The anti-torsion plate body 11 has an integrally formed front extension plate 31 on the edge facing the forefoot of the human foot. This is beneficial when the shoe is put into the shoe, and when pushing off the ground, the foot can step on the front extension plate 31 that extends forward from the anti-torsion plate body 11. When moving, the anti-torsion plate body 11 is subjected to force and bends. Then, after pushing off the ground, the bent anti-torsion plate body 11 generates additional propulsion force.
[0032] The anti-torsion plate body 11 has an integrally formed rear extension plate 41 on the edge facing the heel of the human foot, which helps to improve the overall deformation resistance and torsional strength of the anti-torsion plate body 11.
[0033] The anti-torsion plate body 11 is also integrally formed with a reinforcing rib 25 around the edge of the stable structure 26 at the bottom edge of the stable structure 26, which helps to improve the strength of the anti-torsion plate body 11 and makes it less prone to torsion deformation.
[0034] The third inclined plate 23 has an integrally formed pressure-reducing groove 24, which allows the first inclined plate 21, the second inclined plate 22, and the third inclined plate 23 to undergo slight deformation when subjected to vertical downward stepping and squeezing, while ensuring longitudinal torsional resistance, thereby improving the cushioning performance of the shoe after it is installed and preventing foot discomfort.
[0035] This utility model also provides a sports shoe, including a midsole 2 and an outsole 3 fixed to the bottom surface of the midsole 2. An upper body 4 is fixedly provided on the midsole 2. The upper body 4 forms an entry point 5 at the heel position of the human foot. An anti-torsion plate 1 is embedded in the middle section of the bottom surface of the midsole 2. The anti-torsion plate 1 includes an anti-torsion plate body 11. A stabilizing structure 26 is integrally formed at the center of the anti-torsion plate body 11. The stabilizing structure 26 includes a first inclined plate 21 integrally formed at the center of the anti-torsion plate body 11 and a second inclined plate 22 integrally formed at the center of the anti-torsion plate body 11. The stabilizing structure 26 also includes a third inclined plate 23 integrally formed at the center of the anti-torsion plate body 11. The edges of the first inclined plate 21, the second inclined plate 22, and the third inclined plate 23 converge and combine to form a triangular pyramid-shaped upward-convex cavity. The anti-torsion plate body 11 is located on the side corresponding to the arch of the human foot and is also integrally formed with an upper support plate 51. In use, the foot enters the cavity formed by the midsole 2 and the upper body 4 through the insertion port 5, and the shoe is then put on. During production, the anti-torsion plate 1 is glued and embedded into the bottom surface of the midsole 2, and then the rubber outsole 3 is glued and fixed to the midsole 2. The anti-torsion plate 1 is formed by molding during production. The anti-torsion plate body 11 can be made of TPU or carbon fiber material. The anti-torsion plate body 11 provides anti-torsion capability. When installed in the midsole of a shoe, if subjected to relatively mild torsional force, the anti-torsion plate 11 can absorb and counteract the torsional force through its own strength. An upper support plate 51 is integrally formed on the side of the anti-torsion plate 11 corresponding to the arch of the foot. After being installed in the athletic shoe, the upper support plate 51 provides upward support to the arch of the foot. During intense lateral movements while wearing the athletic shoe, it provides excellent support for the arch, preventing overextension and thus avoiding rapid fatigue. This results in good wearing comfort. Furthermore, during high-intensity lateral push-offs, the anti-torsion plate 11 is subjected to... When subjected to torsional force, the torsional force on the anti-torsion plate body 11 can be resisted by the stabilizing structure 26. Since the stabilizing structure 26 is composed of the first inclined plate 21, the second inclined plate 22 and the third inclined plate 23, and extends upward to form a triangular pyramid structure, when subjected to torsional force from the front and rear, the triangular structure of the front section of the triangular pyramid structure formed by the three inclined plates can provide high stability and is not easy to deform. When subjected to lateral torsional force, the sides of the triangular pyramid structure formed by the three inclined plates also form a stable triangular structure and are not easy to deform. This greatly improves the torsional resistance of the anti-torsion plate, making the anti-torsion plate less prone to deformation and more stable.
[0036] The anti-torsion plate body 11 has an integrally formed front extension plate 31 on the edge facing the forefoot of the human foot. This is beneficial when the anti-torsion plate body 11 is installed in sports shoes. When pushing off the ground, the foot can step on the front extension plate 31 that extends forward from the anti-torsion plate body 11. When moving, the anti-torsion plate body 11 is subjected to force and bends. Then, after pushing off the ground, the bent anti-torsion plate body 11 generates additional propulsion force.
[0037] The anti-torsion plate body 11 has an integrally formed rear extension plate 41 on the edge facing the heel of the human foot, which helps to improve the overall deformation resistance and torsional strength of the anti-torsion plate body 11 and improve the integrity of the midsole 2.
[0038] The anti-torsion plate body 11 is also integrally formed with a reinforcing rib 25 around the edge of the stable structure 26 at the bottom edge of the stable structure 26, which helps to improve the strength of the anti-torsion plate body 11 and makes it less prone to torsion deformation.
[0039] The third inclined plate 23 has an integrally formed pressure-reducing groove 24, which allows the first inclined plate 21, the second inclined plate 22, and the third inclined plate 23 to undergo slight deformation when subjected to vertical downward stepping and squeezing, while ensuring longitudinal torsional resistance, thereby improving the cushioning performance of the shoe after it is installed and preventing foot discomfort.
[0040] The working principle of this invention is as follows: When using this invention, the foot enters the cavity formed by the midsole 2 and the upper 4 through the insertion port 5, thus completing the wearing process. During production, an anti-torsion plate 1 is glued and embedded into the bottom surface of the midsole 2, followed by a rubber outsole 3 glued and fixed to the midsole 2. The anti-torsion plate 1 is molded using a mold. The anti-torsion plate body 11 can be made of TPU or carbon fiber. The anti-torsion plate body 11 provides anti-torsion capabilities. When installed in the midsole of the shoe, if subjected to a relatively slight torsional force, the strength of the anti-torsion plate body 11 itself can offset and absorb the torsional force. An upper support plate 51 is integrally formed on the side of the anti-torsion plate body 11 corresponding to the arch of the foot. After being installed in the athletic shoe, the upper support plate 51 provides upward support to the arch of the foot, facilitating vigorous lateral movement while wearing the athletic shoe. When worn, it can provide good support for the arch of the foot, preventing the arch from overstretching during exercise and thus avoiding rapid fatigue. It is comfortable to wear. At the same time, when the anti-torsion plate body 11 is subjected to torsional force due to high-intensity lateral push-off during wear, the stabilizing structure 26 can resist the torsional force on the anti-torsion plate body 11. Since the stabilizing structure 26 is composed of the first inclined plate 21, the second inclined plate 22, and the third inclined plate 23, and extends upward to form a triangular pyramid structure, it can provide high stability and is not easy to deform when subjected to frontal and rear torsional forces through the triangular structure of the front section of the triangular pyramid structure formed by the three inclined plates. When subjected to lateral torsional forces, the sides of the triangular pyramid structure formed by the three inclined plates also form a stable triangular structure and are not easy to deform. This greatly improves the torsional resistance of the anti-torsion plate, making the anti-torsion plate less prone to deformation and more stable.
