Description

Technical Field

[0001] This utility model relates to the field of footwear and apparel technology, specifically to a lightweight, high-strength shoe upper. Background Technology

[0002] Shoes are a type of clothing accessory whose function is to protect and cover the user's feet. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, while the upper is the upper part that is located on top of the sole. The upper covers the user's foot and connects with the sole to fix the sole to the user's foot, preventing the sole from falling off. The design of the upper can effectively improve the integration of the shoe and foot, and make the shoe more protective of the foot and provide better warmth.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: In order to ensure high comfort and prevent stuffiness when wearing shoes, existing shoe uppers are made of a large area of ​​mesh material. The mesh material has a large number of holes, which can effectively improve breathability, but it will cause the shoe upper's resistance to deformation to decrease significantly. As a result, it can only be used for low-intensity exercise. When engaging in strenuous exercise, the shoe upper will deform too much, causing the foot to be unable to be fixed in the shoe upper, which can easily lead to sports injuries such as ankle sprains. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a lightweight, high-strength shoe upper that offers high comfort and strength.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight, high-strength shoe upper, comprising a shoe upper body and an opening integrally formed on the shoe upper body at the heel position of the human foot by cutting. A first reinforcing layer composed of cross-shaped and cross-shaped yarns is sewn and fixed on both sides of the shoe upper body at the opening. A second reinforcing layer with the same structure as the first reinforcing layer is sewn and fixed on the corresponding position of the lateral metatarsal bone of the foot. A longitudinal reinforcing layer composed of longitudinal yarns is provided on both sides of the shoe upper body, extending from the middle section of the shoe upper body to the forefoot edge of the shoe upper body. A mesh ventilation opening is provided on the shoe upper body at the corresponding position of the big toe of the human foot. A high-density woven strip is provided on the outer side of the shoe upper body. A heat-pressed reinforcing layer with multiple perforations is provided on the inner side of the shoe upper body, extending from the forefoot edge of the shoe upper body to the inner edge of the shoe upper body.

[0006] A further improvement is that the upper body includes a high-density woven layer and several through grooves integrally formed on the high-density woven layer. A mesh strip is sewn and fixed to the bottom surface of the through groove, and a reinforcing yarn is sewn and fixed to the top surface of the high-density woven layer. A through groove connecting yarn is also sewn and fixed to the inner wall of the middle section of the through groove.

[0007] After adopting the above technical solution, the beneficial effects of this utility model are as follows: The main body of the shoe upper is woven from a high-density woven layer and has a through groove. The bottom of the through groove is sealed by a mesh strip. During the wearing process, the heat generated by the foot can be dissipated outward through the mesh strip and the through groove. External airflow can also enter through the through groove and through the mesh strip, blowing on the foot. This makes the foot breathable and comfortable when wearing, and not stuffy. In addition, the through groove greatly reduces the weight of the shoe upper, resulting in a good lightweight effect and making it less tiring to wear. Attached Figure Description

[0010] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0011] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a lightweight, high-strength shoe upper, including a shoe upper body 1 and an opening 2 integrally formed on the shoe upper body 1 at the heel position of the human foot. A first reinforcing layer 4, composed of cross-shaped horizontal and vertical yarns, is sewn and fixed to both sides of the opening on the shoe upper body 1. A second reinforcing layer 3, with the same structure as the first reinforcing layer 4, is sewn and fixed to the corresponding position of the lateral epicondyle of the foot on the shoe upper body 1. Longitudinal reinforcing layers 5, composed of vertical yarns, are provided on both sides of the shoe upper body 1, extending from the middle section of the shoe upper body 1 to the forefoot edge. A mesh ventilation opening 7 is provided on the shoe upper body 1 at the corresponding position of the big toe. A high-density woven strip 8 is provided on the outer side of the shoe upper body 1. The upper body 1 has a heat-pressed reinforcing layer 6 with multiple perforations on its inner side, extending from the forefoot edge to the inner edge of the upper body 1. The upper body 1 includes a high-density woven layer 51 and several through-grooves 52 integrally formed on the high-density woven layer 51. The warp and weft density of the high-density woven layer 51 is preferably 60-100 threads / inch. Mesh strips 54 are sewn and fixed to the bottom surface of the through-grooves 52, and reinforcing yarns 53 are sewn and fixed to the top surface of the high-density woven layer 51. Through-grooves connecting yarns 55 are also sewn and fixed to the inner wall of the middle section of the through-grooves 52. During molding, the high-density woven layer 51 of the upper body 1 is first formed by a high-density weaving method, and the through-grooves 52 are formed on the high-density woven layer 51 by laser cutting or ultrasonic cutting. The cut edges are treated with high-frequency hot pressing or resin coating to prevent the braided yarn from fraying. The penetration grooves 52 are vertically distributed, and mesh strips 54 are sewn into the bottom of each groove. Reinforcing yarns 53 are sewn onto the high-density braided layer 51. Simultaneously, penetration groove connecting yarns 55 are sewn into the penetration grooves 52. High-strength polyester fiber yarn is used as the penetration groove connecting yarn 55, and it is sewn onto the groove wall in a zigzag path. This penetration groove connecting yarn 55 is sewn back and forth between the two opposing inner walls of the penetration groove 52 in a zigzag path, forming a mesh connection structure to constrain the deformation of the penetration grooves 52 under stress and prevent them from expanding. The upper body 1 is woven from polyester yarn, which is a high-strength, low-elongation polyester multifilament. The fineness is preferably 300D-600D, and more preferably, Nylbond yarn with similar properties can be used. Then, an opening 2 is formed on the upper body 1 by cutting, and a first reinforcing layer 4 composed of cross-shaped cross-weaves is sewn on both sides of the opening 2 to improve the strength of the upper at the opening 2, allowing for better ankle protection. A second reinforcing layer 3 with the same structure as the first reinforcing layer 4 is sewn at the corresponding position on the lateral aspect of the foot, providing better lateral deformation resistance and stronger support, better cradle the foot during exercise, and ensure wearing stability. This, combined with a high-density woven strip 8 sewn onto the outer side of the upper body 1, further enhances the deformation resistance of the outer side of the upper.To further improve stability, ventilation openings 7 are cut and shaped, and mesh fabric is sewn onto the ventilation openings 7 to allow heat and moisture generated during exercise to escape, ensuring the feet stay cool. Subsequently, a hot-pressed reinforcement layer 6 is formed on the upper body 1 from the forefoot edge to the inner edge of the upper body 1 using high-temperature hot pressing TPU material. Specifically, the TPU film is hot-pressed and laminated using a hot-pressing mold at a temperature of 150-180°C and a pressure of 0.3-0.6MPa, which significantly increases the strength of the upper body 1 at this location. Then, a large number of perforations are formed on the hot-pressed reinforcement layer 6 by punching holes. Compared with ordinary hot-pressed layers, it ensures strength while also having better breathability. At the same time, this utility model forms a complete support frame by setting local reinforcement structures in key stress-bearing parts such as the first reinforcement layer 4, the second reinforcement layer 3, the longitudinal reinforcement layer 5, the high-density woven strip 8, and the hot-pressed reinforcement layer 6. The frame bears the main stress during movement, thus compensating for the weakening of overall strength caused by the perforation grooves 52, achieving a balance between lightweight and high strength. During wear, heat generated by the feet can dissipate outward through the mesh strips 54 of the upper body 1 and the perforation grooves 52. External airflow can also enter through the perforation grooves 52 and pass through the mesh strips 54, blowing onto the feet. This ensures good breathability, high comfort, and prevents stuffiness. Furthermore, the perforation grooves 52 significantly reduce the weight of the upper body 1, resulting in excellent lightweight performance and reducing foot fatigue during wear.

[0012] The working principle of this utility model is as follows: During the molding process, a high-density woven layer 51 of the shoe upper body 1 is first formed using a high-density weaving method. Penetrating grooves 52 are formed by cutting into the high-density woven layer 51. The penetrating grooves 52 are vertically distributed, and mesh strips 54 are sewn into the bottom of the penetrating grooves 52. Reinforcing yarns 53 are then sewn onto the high-density woven layer 51. Simultaneously, penetrating groove connecting yarns 55 are sewn into the penetrating grooves 52. The shoe upper body 1 is woven using polyester yarn, preferably Nylbond yarn. Subsequently, an opening 2 is formed on the upper body 1 by cutting, and a first reinforcing layer 4 composed of cross-shaped horizontal and vertical yarns is sewn on both sides of the opening 2 to improve the strength of the upper at the opening 2, so that it can better protect the ankle. A second reinforcing layer 3 with the same structure as the first reinforcing layer 4 is sewn on the corresponding position of the lateral epicondyle of the foot, so that it can better provide lateral deformation resistance, making it more wrap-around, and better supporting the foot during exercise to ensure wearing stability. The high-density woven strip 8 sewn on the outside of the upper body 1 further improves the deformation resistance of the outer side of the upper and further improves stability. At the same time, a ventilation opening 7 is cut and shaped, and a mesh is sewn on the ventilation opening 7 to expel the heat and moisture generated during exercise, so as to keep the feet cool. Then, a hot-pressed reinforcing layer 6 is formed on the upper body 1 from the forefoot edge to the inner edge of the upper body 1 by high temperature hot pressing TPU material, which greatly improves the strength of the upper body 1 at this position. The upper 6 has a large number of perforations formed by punching. Compared with ordinary hot-pressed layers, it can ensure strength while also having better breathability. During wear, the heat generated by the feet can be dissipated outward through the mesh strips 54 of the upper body 1 and the perforation grooves 52. External airflow can also enter through the perforation grooves 52 and pass through the mesh strips 54, blowing on the feet. This makes the feet breathable and comfortable when wearing, and not stuffy. In addition, the perforation grooves 52 greatly reduce the weight of the upper body 1, resulting in good lightweight effect and less foot fatigue when wearing.
