Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear and apparel technology, specifically to a double-layer air curtain 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 existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: In order to ensure that the heat of the foot can be dissipated efficiently when wearing shoes, existing shoe uppers often use a single layer of mesh fabric to make the shoe upper. However, shoe uppers made of single layer of mesh fabric have low strength and are prone to excessive deformation during movement, which cannot fully support the foot. In addition, the design is monotonous and the aesthetics are poor. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a double-layer air curtain shoe upper that is aesthetically pleasing, breathable, and provides good support.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer air curtain shoe upper, comprising an air curtain shoe upper body and an opening integrally formed on the air curtain shoe upper body at the heel position of the human foot, the air curtain shoe upper body comprising a mesh fabric layer and a lower mesh fabric layer disposed below the mesh fabric layer, an air guiding unit layer is embedded between the lower surface of the mesh fabric layer and the upper surface of the lower mesh fabric layer, the air guiding unit layer being composed of a plurality of spherical woven bodies.
[0006] A further improvement is that the mesh fabric layer has several ventilation holes integrally formed on it.
[0007] A further improvement is that the lower mesh layer is integrally formed with several lower ventilation holes that penetrate the lower mesh layer.
[0008] A further improvement is that an upper heddle layer is sewn onto the upper surface of the mesh fabric layer.
[0009] A further improvement is that a lower heddle layer is sewn onto the lower surface of the lower mesh fabric layer.
[0010] A further improvement is that a mesh layer extending to the forefoot position of the air curtain upper is sewn on both sides of the upper.
[0011] A further improvement is that a high-density jacquard layer is sewn onto the edge of the forefoot of the mesh cover.
[0012] A further improvement is that a side reinforcement layer is sewn and fixed onto the mesh layer.
[0013] A further improvement is that: the side reinforcement layer is woven with microfiber on both sides and has a fluid sculpted layer that extends to the position of the side reinforcement layer on the forefoot of the human body, and the fluid sculpted layer has several corrugated ventilation grooves integrally formed on it.
[0014] A further improvement is that the air curtain upper body has an integrally formed tongue mounting opening extending towards the front end of the air curtain upper body at the edge of the inlet.
[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows: This utility model has an air-guiding unit layer between the lower mesh layer and the upper mesh layer. The air-guiding unit layer is composed of a spherical woven fabric formed by breathable fibers, which creates a gap between the air-guiding unit layer and the upper and lower mesh layers. When hot air and moisture enter the gap, they are squeezed out of the gap as the foot moves and is discharged outward through the upper mesh layer. This allows the upper to maintain excellent breathability and heat dissipation performance while having high strength and support, providing good protection and high wearing comfort.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a double-layer air curtain shoe upper, including an air curtain shoe upper body 1 and an opening 2 integrally formed on the air curtain shoe upper body 1 at the heel position of the human foot. The air curtain shoe upper body 1 includes a mesh fabric layer 12 and a lower mesh fabric layer 15 disposed below the mesh fabric layer 12. An air guiding unit layer 13 is embedded between the lower surface of the mesh fabric layer 12 and the upper surface of the lower mesh fabric layer 15. The air guiding unit layer 13 is composed of several spherical woven bodies. During production, the lower mesh fabric layer 15 is formed first. A ventilation unit layer 13, composed of multiple spherical woven bodies, is embedded on the upper surface of the lower mesh layer 15. These spherical woven bodies are formed using breathable yarn, which is a blend of 52.7% recycled polyester and 47.3% TPU material, providing high strength and good breathability. A mesh layer 12 is then laid on top of the ventilation unit layer 13, and the mesh layer 12 is fixed to the lower mesh layer 15 by intermittent stitching. Finally, the air curtain upper 1 is cut and installed onto the midsole. The foot is inserted through the insertion point 2. Since the air-guiding unit layer 13 is composed of a spherical woven fabric formed from breathable fibers, gaps exist between the air-guiding unit layer 13 and the upper mesh layer 12 and lower mesh layer 15. During wear, moisture and heat generated by the foot pass through the lower mesh layer 15 and enter the gaps. As the foot moves, the moisture and heat compress the upper, causing the gaps to periodically compress and expand. During compression, the moisture and heat are forced out of the gaps. And through the mesh layer 12, it can expel outwards. When it expands, it can pump the moisture and heat generated by the feet as well as the cold air from the outside into the gap, keeping the feet cool. According to experiments, compared with the upper with only upper and lower mesh layers, the breathability and heat dissipation are improved by 20%. The composite layer structure of the upper and lower mesh layers and the air-guiding unit layer 13 provides high tensile strength and deformation resistance. Thus, the upper can maintain excellent breathability and heat dissipation performance while having high strength and support, good protection and high wearing comfort. The mesh fabric layer 12 has several upper ventilation holes 14 integrally formed on it, which helps to further improve the heat dissipation and breathability of the mesh fabric layer 12, while reducing the weight of the mesh fabric layer 12 and further improving the lightweighting. The lower mesh layer 15 has several vent holes 16 integrally formed on it, which helps to further improve the heat dissipation and breathability of the lower mesh layer 15, while reducing the weight of the lower mesh layer 15 and further improving the lightweighting. The upper surface of the net fabric layer 12 is also sewn with an upper heddle layer 11, which is beneficial to cover the net fabric layer 12 through the upper heddle layer 11, so that the net fabric layer 12 can maintain its breathability while further improving its support and deformation resistance. The lower surface of the lower mesh fabric layer 15 is also sewn with a lower heddle layer 17, which is beneficial to cover the lower mesh fabric layer 15 through the lower heddle layer 17, so that the lower mesh fabric layer 15 can maintain breathability while further improving its support and deformation resistance, and at the same time making the surface that directly contacts the foot softer, resulting in higher wearing comfort. The air curtain upper 1 has a mesh layer 8 sewn on both sides, extending to the forefoot position of the air curtain upper 1. This mesh layer 8 helps to improve the strength of the sides and forefoot position of the air curtain upper 1, making it more supportive without affecting breathability. The mesh layer 8 is sewn with a high-density jacquard layer 7 at the edge of the forefoot, which helps to improve the strength of the forefoot edge of the shoe, making it less prone to tearing. At the same time, it makes the forefoot area of the shoe stronger, more stable and less prone to deformation when stepped on, and provides better protection. A side reinforcement layer 4 is also sewn and fixed on the mesh layer 8. The side reinforcement layer 4 can be a high-density fabric layer woven from microfiber, which is beneficial to improve the strength of the side of the shoe upper and is not prone to excessive deformation when subjected to force, so that it can better support the foot when making lateral movements. The side reinforcement layer 4 has a fluid sculpting layer 5 on both sides woven with microfiber and extends to the corresponding position of the side reinforcement layer 4 on the forefoot. The fluid sculpting layer 5 is a wavy layer formed by microfiber weaving. Several wavy ventilation grooves 6 are integrally formed on the fluid sculpting layer 5, which helps to further improve the strength of the shoe upper through the fluid sculpting layer 5, and at the same time makes the shoe upper produce a visual depth effect of 4-7 layers of water ripple diffusion. Combined with the wavy ventilation grooves 6, it achieves a more three-dimensional wavy layering effect, which is more beautiful and effectively improves breathability. The air curtain upper body 1 is integrally formed with a tongue mounting opening 3 extending towards the front end of the air curtain upper body 1 at the edge of the insertion opening 2. This facilitates the insertion of the tongue through the tongue mounting opening 3, making the tongue installation simpler and more convenient.
[0020] The working principle of this utility model is as follows: During production, the lower mesh layer 15 is first formed, and a multiple spherical woven body-based air-guiding unit layer 13 is embedded on the upper surface of the lower mesh layer 15. The spherical woven body is woven from breathable yarn, which is made of 52.7% recycled polyester mixed with 47.3% TPU material, possessing high strength and good breathability. Then, the upper mesh layer 12 is laid on the air-guiding unit layer 13, and the upper mesh layer 12 and the lower mesh layer 15 are fixed together by intermittent stitching. The air curtain upper body 1 is then cut and inserted into the midsole, allowing the foot to be inserted through the entry point 2. Because the air-guiding unit layer 13 is composed of spherical woven bodies formed from breathable fibers, there is a certain airflow between the air-guiding unit layer 13 and the upper mesh layer 12 and the lower mesh layer 15. During wear, moisture and heat generated by the feet pass through the lower mesh layer 15 and enter the gap. As the feet move, the moisture and heat compress the upper, causing the gap to periodically compress and expand. During compression, the moisture and heat are forced out of the gap and discharged outward through the mesh layer 12. During expansion, moisture and heat generated by the feet, as well as cold air from the outside, are pumped into the gap, keeping the feet cool. Experiments have shown that compared to uppers with separate upper and lower mesh layers, breathability and heat dissipation are improved by 20%. The composite layer structure of the upper and lower mesh layers, combined with the air-guiding unit layer 13, provides high tensile strength and deformation resistance. This allows the upper to maintain excellent breathability and heat dissipation while having high strength and support, providing good protection and high wearing comfort.
