Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to an outdoor shoe upper that laterally wraps around the foot. 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] While the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: In order to improve the support of the foot and prevent excessive deformation during outdoor sports and thus the risk of sports injuries, existing outdoor shoe uppers often use high-strength yarns for high-density weaving and reinforcement on the sides of the upper. Although this can effectively improve the deformation resistance of the upper sides, it will lead to a significant increase in the stiffness of the upper sides, which seriously affects the wearing comfort. At the same time, the increased stiffness of the upper makes it difficult to bend during walking, which can easily cause the foot to get stuck. Moreover, walking requires more force to overcome the bending resistance of the upper, making the feet more prone to fatigue. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an outdoor shoe upper that offers high comfort, does not restrict foot movement, and provides good lateral support for the foot.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor shoe upper that laterally wraps the foot, comprising an upper body and an opening integrally formed on the upper body at the heel position of the human foot, wherein the upper body at the heel position of the human foot has a heel covering reinforcement layer that wraps the heel edge of the upper body by hot pressing, and the side of the upper body has a lateral wrapping structure formed by high-density yarn woven by high-density weaving method through flat embroidery process.

[0006] A further improvement is that a first reinforcing strip is sewn and fixed to one side of the upper body, extending through the forefoot position of the upper body and finally reaching the other side of the upper body. The first reinforcing strip is formed by high-density yarn through a high-density weaving method.

[0007] A further improvement is that a forefoot breathable layer is sewn and fixed to the forefoot position of the shoe upper body.

[0008] A further improvement is that several side ventilation panels are sewn and fixed on both sides of the shoe upper body.

[0009] A further improvement is that the upper body is also equipped with a reinforcing layer for the insertion opening, which is fixed by heat pressing at the edge of the insertion opening.

[0010] A further improvement is that a second reinforcing strip is sewn and fixed to the edge of the reinforcing layer at the entrance of the shoe upper body. The second reinforcing strip is formed by high-density yarn through a high-density weaving method.

[0011] A further improvement is that a forefoot reinforcement layer is also fixed to one side edge of the upper body by heat pressing, surrounding the forefoot position edge of the upper body and extending to the other side edge of the upper body.

[0012] A further improvement is that a suede layer is sewn and fixed to the forefoot reinforcement layer located on the forefoot position of the upper body.

[0013] A further improvement is made to the lateral wrapping structure, which includes two sets of side pull strip structures symmetrically distributed on both sides of the upper body. The side pull strip structure includes a first pull strip composed of several gradually shortening quadrilateral strips. The quadrilateral strips are woven from high-density yarn using a high-density weaving method. The first pull strip extends obliquely from the heel of the upper body towards the forefoot of the upper body. The side pull strip structure also includes a second, third, and fourth pull strip, which are the same as the first pull strip structure. The second pull strip extends obliquely from the heel of the upper body towards the insertion point. The third pull strip extends obliquely from one side edge of the upper body towards the insertion point. The fourth pull strip extends obliquely from one side edge of the upper body towards the forefoot of the upper body.

[0014] The beneficial effects of this utility model after adopting the above technical solution are as follows: When wearing this utility model, tightening the shoelaces will cause the sides of the shoe upper to be pulled and contracted, conforming to the surface of the foot. At the same time, the heel wrapping reinforcement layer at the heel of the shoe upper will wrap and fix the heel of the foot. During exercise, the heel of the foot can be locked and will not swing from side to side, thus preventing sports injuries, and will always maintain a neutral position. The tightened shoelaces will drive the first and second inclined pull strips to cover the heel and ankle of the foot. The quadrilateral strips formed by high-density yarn and weaving method have high stability and resistance. The first and second straps, which are designed for deformation, cover and restrain the ankle area, making it difficult for the upper to deform. This provides sufficient fixation for the ankle and ensures safety during exercise. Meanwhile, the third and fourth straps cover the sides of the foot, making the upper more resistant to deformation in this area. Since they do not fully cover the sides of the upper, especially the folds, the upper remains flexible when bent. This makes bending easier and prevents the foot from getting stuck while walking. While ensuring the strength of the upper, this design significantly improves wearing comfort and reduces foot fatigue. Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Figure 1 This is a top view of the structure of the shoe upper of this utility model after it has been unfolded. Detailed Implementation

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] See Figure 1As shown, the technical solution adopted in this specific embodiment is: an outdoor shoe upper that laterally wraps the foot, including an upper body 1 and an opening 2 integrally formed on the upper body 1 at the heel position of the human foot. A heel-wrapping reinforcement layer 3, which wraps around the heel edge of the upper body 1, is fixed to the upper body 1 at the heel position by heat pressing. The side of the upper body 1 is formed with a lateral wrapping structure woven from high-density yarn using a high-density weaving method through a flat embroidery process. The lateral wrapping structure includes two sets of side pull strip structures symmetrically distributed on both sides of the upper body 1. The side pull strip structure includes a first pull strip 51 composed of several gradually shortening quadrilateral strips. Specifically, the quadrilateral strips are parallelogram structures, and the multiple parallelogram structures are arranged with a gap of 0.1-0.3 cm along the extension direction of the first pull strip 51, with their area gradually decreasing along the extension direction. The quadrilateral strips are woven from high-density yarn using a high-density weaving method. The first pull strip 51 extends obliquely from the heel of the upper body 1 towards the forefoot of the upper body 1. The side pull strip structure also includes a second pull strip 52, a third pull strip 53, and a fourth pull strip 54, which are identical to the first pull strip 51. The second pull strip 52 extends obliquely from the heel of the upper body 1 towards the insertion opening 2. The third pull strip 53 extends obliquely from one side edge of the upper body 1 towards the insertion opening 2. The fourth pull strip 54 extends obliquely from one side edge of the upper body 1 towards the forefoot of the upper body 1. During molding, the fabric for the upper body 1 is first woven into shape using abrasion-resistant yarn. Then, the upper body 1 is cut. Subsequently, the insertion opening 2 is cut into the upper body 1 at the heel position of the formed upper body 1. Then, a thermoplastic film is hot-pressed onto the heel edge of the upper body 1 to form a heel covering reinforcement layer 3. Specifically, a TPU film is used at 150°C and 0°C.Under 4MPa pressure, the shoe is hot-pressed for 10-15 seconds. The heel area of ​​the upper body 1 is hardened by covering the entire heel area with a heel reinforcement layer 3. Subsequently, two sets of symmetrically distributed side pull structures are set on both sides of the upper body 1. Each side pull structure consists of a first pull bar 51, a second pull bar 52, a third pull bar 53, and a fourth pull bar 54, all composed of multiple quadrilateral strips formed by high-density yarn using a high-density weaving method. The formed first pull bar 51 and second pull bar 52 are distributed... The upper body 1 has a side panel at the heel, while the third and fourth tension strips 53 and 54 are distributed on the side of the upper body 1 and extend towards the forefoot. The edge of the upper can then be sewn into the midsole, and the shoelaces are threaded through the front of the insertion opening 2. The foot can then be put through the insertion opening 2. When wearing the shoe, tightening the shoelaces causes the sides of the upper body 1 to be pulled and contracted, conforming to the surface of the foot. Simultaneously, the heel support reinforcement layer 3 at the heel of the upper body 1 provides support to the heel area. The shoelaces provide a secure fit, locking the heel area during exercise to prevent lateral movement and potential injury, maintaining a neutral position. Tightened laces activate the first and second pull strips 51 and 52, which cover the heel and ankle areas. The high-density yarn and woven quadrilateral strips offer high stability and resistance to deformation. These first and second pull strips 51 and 52 cover and restrain the ankle, preventing deformation of the upper body 1 and ensuring adequate ankle support for safe movement. Simultaneously, the third and fourth pull strips 53 and 54 cover the sides of the foot, enhancing the upper body 1's resistance to deformation. Since they don't fully cover the sides, especially the folds, the upper body 1 remains flexible during bending, reducing strain and preventing foot constriction. This design ensures upper strength while significantly improving comfort and reducing foot fatigue. The high-density yarn mentioned above refers to synthetic fiber yarn with a linear density of 300 denier (D) or higher and high strength, preferably high-strength nylon yarn or polyester fiber yarn. High-density weaving refers to a weaving process that uses double-layer or jacquard weaving structure to make the warp and weft density of the fabric reach more than 80 threads / inch, thereby obtaining high tensile strength and low elongation. Flat embroidery process refers to, in the context of this utility model, specifically a computer embroidery process that uses single-needle lockstitch to embroider and fix the above-mentioned high-density woven tape to the base fabric of the shoe upper.

[0019] A first reinforcing strip 10 is sewn and fixed on one side of the upper body 1, extending through the forefoot position of the upper body 1 and finally reaching the other side of the upper body 1. The first reinforcing strip 10 is formed by high-density yarn through high-density weaving, which is beneficial to surround the side of the upper body 1 and the forefoot position through the first reinforcing strip 10, thereby improving the deformation resistance of the side of the upper body 1 and supporting the forefoot, making it less prone to collapse. The forefoot area of ​​the upper body 1 is sewn and fixed with a forefoot breathable layer 7, which helps to improve the breathability of the forefoot area, making it less stuffy and more comfortable to wear. Several side ventilation panels 8 are sewn and fixed on both sides of the upper body 1, which helps to improve the breathability of the sides of the upper body 1. Combined with the forefoot ventilation layer 7, airflow can enter from the forefoot ventilation layer 7 and flow out from the side ventilation panels 8, further improving the comfort of wearing. The upper body 1 is also fixed with a reinforcing layer 11 at the edge of the insertion opening 2 by hot pressing, which helps to improve the strength of the upper body 1 at the insertion opening 2, making it less likely to break after being tightened by the shoelaces; A second reinforcing strip 9 is sewn and fixed on the edge of the reinforcing layer 11 at the entrance of the shoe body 1. The second reinforcing strip 9 is formed by high-density yarn through high-density weaving, which helps to further improve the overall strength of the shoe body 1, making it less prone to deformation when worn and improving safety during sports. One edge of the upper body 1 is also fixed with a forefoot reinforcement layer 4 that surrounds the forefoot edge of the upper body 1 and extends to the other edge of the upper body 1 by heat pressing. This helps to improve the strength of the forefoot edge of the upper body 1, making it less prone to cracking. At the same time, it makes the forefoot edge of the upper body 1 harder. When the upper body 1 comes into contact with hard objects during outdoor sports, it can resist the impact of hard objects, prevent foot injuries, and reduce the probability of damage to the upper body 1. The forefoot reinforcement layer 4 is located on the forefoot of the upper body 1 and is also sewn with a suede layer 6, which helps to further improve the wear resistance and impact resistance of the upper body 1 and further improve the protection of the foot. The hot-pressing fixation mentioned above refers to the use of the hot bonding process in conventional shoe material processing to melt and bond thermoplastic materials (such as thermoplastic polyurethane TPU film, ethylene-vinyl acetate copolymer EVA film) to the corresponding position of the shoe upper body under specific temperature (such as 120℃-180℃) and pressure.

[0020] To verify the technical effect of the outdoor shoe upper described in this utility model, the following comparative experiment was conducted: 1. Experimental Samples: Experimental group: Finished shoes (shoe size: 42) made from outdoor shoe uppers manufactured using the technical solution of this utility model.

[0021] Control group: Finished shoes of the same size made from a mainstream outdoor shoe on the market (whose upper is reinforced with traditional high-strength woven fabric with a large area on the side).

[0022] 2. Test Items and Results: (1) Dynamic foot wrapping and stability test Test method: The plantar pressure distribution test system (RSscan International system) was used to conduct a constant speed (8km / h) running test on an indoor treadmill. The peak pressure and pressure distribution stability in the midfoot lateral region were measured in both the experimental and control groups during the running process (expressed as the standard deviation of the pressure center trajectory offset).

[0023] Test results:

[0024] (2) Forefoot bending flexibility (bending stiffness) test Test method: In accordance with industry practice, a digital fabric bending stiffness tester was used to cut samples of the upper of the experimental group and the control group corresponding to the bending area of ​​the metatarsophalangeal joint, and to measure their bending stiffness (unit: cN·cm²).

[0025] Test results:

[0026] (3) Subjective evaluation of wearing comfort Test Method: Twenty participants with outdoor exercise habits (standard foot type) were recruited and hiked for one hour wearing shoes from the experimental group and the control group, respectively. A 10-point questionnaire was used to rate three items: "lateral support", "whether the foot is pinched or hurts when bending", and "overall comfort" (10 points is the best).

[0027] Test results:

[0028] (4) Air permeability verification Test method: According to the national standard GB / T 5453, the air permeability of the fabric was tested using a fabric air permeability meter to test the air permeability (mm / s) of the experimental group (forefoot air permeable layer + side air permeable area) and the control group (corresponding area).

[0029] Test results:

[0030] 3. Experimental Conclusion: The above experimental data comprehensively demonstrate that, compared with outdoor shoe uppers using traditional side reinforcement technology, the outdoor shoe upper with lateral foot wrapping provided by this utility model has the following significant improvements: It achieves superior dynamic stability: foot sway is reduced by 37%, providing more reliable protection in complex terrain.

[0031] Significantly improved bending comfort: bending stiffness was reduced by 34%, and the "no foot jamming" score was outstanding in subjective evaluation, effectively solving the pain points of stiffness and foot jamming in traditional technology.

[0032] It achieves an ideal balance between support and comfort: while providing sufficient lateral support, the overall wearing comfort is significantly improved.

[0033] Enhanced breathability: The breathable structure design significantly improves breathability and enhances the foot microenvironment.

[0034] These data fully demonstrate the beneficial effects of the technical solution described in this utility model, namely, successfully solving the technical problem of "difficulty in balancing support and comfort" pointed out in the background art.

[0035] The working principle of this utility model is as follows: During the molding process, firstly, a fabric for the shoe upper body 1 is woven from wear-resistant yarn. Then, the shoe upper body 1 is cut. Next, an opening 2 is cut at the heel position of the molded shoe upper body 1. Then, a thermoplastic film is hot-pressed onto the heel edge of the shoe upper body 1 to form a heel reinforcement layer 3. The heel reinforcement layer 3 covers the entire heel area of ​​the shoe upper body 1, thus hardening the heel area. Finally, two sets of symmetrically distributed side pull structures are provided on both sides of the shoe upper body 1. The pull structure consists of a first pull strip 51, a second pull strip 52, a third pull strip 53, and a fourth pull strip 54, each composed of multiple quadrilateral strips formed by high-density yarn and a high-density weaving method. The first and second pull strips 51 and 52 are located on the side of the heel of the upper body 1, while the third and fourth pull strips 53 and 54 are located on the side of the upper body 1 and extend towards the forefoot. The edge of the upper can then be sewn into the midsole, and the shoelaces are threaded through the front of the insertion opening 2. The foot can then be inserted through the insertion opening 2. When wearing the shoe, tightening the shoelaces... The shoe upper body 1 can be pulled and contracted on both sides by the shoelaces to fit the surface of the foot. At the same time, the heel wrapping reinforcement layer 3 at the heel position of the shoe upper body 1 wraps and fixes the heel position of the foot. During exercise, the heel position of the foot can be locked to prevent lateral movement and sports injuries, and always maintains a neutral position. The tightened shoelaces drive the first pull strip 51 and the second pull strip 52, which are obliquely distributed, to cover the heel and ankle positions of the foot. The quadrilateral strips formed by high-density yarn and weaving method have high stability and deformation resistance. The first pull strip 51 and the second pull strip 52 are composed of these strips. It can cover and restrain the ankle area, making the upper body 1 less prone to deformation, thus fully fixing the ankle area and ensuring sports safety. At the same time, the third and fourth tension strips 53 and 54 cover the sides of the foot, making the upper body 1 more resistant to deformation in the side of the foot. Since it does not fully cover the sides of the upper body 1, especially the bending area, it can still maintain the flexibility of the upper body 1 when bending. Bending is effortless and there is no foot pinching when walking. While ensuring the strength of the upper, it greatly improves wearing comfort and reduces foot fatigue.
