A sole and a shoe

Abstract

This application discloses a shoe sole and a shoe. The sole includes an elastic device, comprising a first support plate, a rigid support portion, a first support frame, a second support plate, and a second support frame. The first support frame is disposed between the lower surface of the first support plate and the upper surface of the second support plate. The rigid support portion is embedded within the first support frame, and the second support frame is disposed on the lower surface of the second support plate. This allows for greater kinetic energy to be provided by the rebound of the first and second support plates during exercise, when the first and second support plates undergo elastic deformation. This improves the user's vertical jump height, starting speed, and agility during exercise. Furthermore, compared to springs or similar spring structures, the first and second support plates in this application have a larger force-bearing area, resulting in greater shoe stability.

Description

Technical Field

[0002] As living standards improve, people have higher and higher requirements for evaluating shoes. How to improve the athletic performance of shoes in specific scenarios is an important indicator for measuring the quality of a pair of shoes. For example, in basketball, how to improve the wearer's athletic performance (such as vertical jump height, starting speed, and agility) is a key focus of basketball shoe research and development.

[0003] Current research on improving athletic performance mainly focuses on adding springs or similar structures to the soles of shoes to provide kinetic energy for activities such as vertical jumps. However, this method of adding springs or similar structures to the soles may lead to shoe instability during exercise due to uneven force distribution on the sole. Summary of the Invention

[0024] Figure 2 This is a schematic diagram of the specific structure of the shoe sole provided in an embodiment of this application. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] As mentioned earlier, improving the sole to enhance shoe quality is a key focus of shoe improvement. For example, by improving the sole's elasticity, users can increase their vertical jump height, starting speed, and agility during exercise.

[0028] Based on this, embodiments of this application provide a shoe sole that can solve the aforementioned technical problems. The shoe sole includes an elastic device 10, which is typically located in the forefoot area of ​​the sole. Figure 1 The diagram shows the specific structure of the elastic device 10, which includes a first support plate 11, a rigid support part 12, a first support frame 13, a second support plate 14, and a second support frame 15.

[0029] Both the first support plate 11 and the second support plate 14 can be used to provide support to improve the stability of the shoe sole, and the stiffness of the second support plate 14 is greater than that of the first support plate 11 to further improve the overall stability.

[0030] The thickness of the first support plate 11 is typically 0.1 to 2.0 mm, for example, 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.3 mm, 1.5 mm, 1.7 mm, 2.0 mm, or other values ​​between 0.1 and 2.0 mm. Similarly, the thickness of the first support plate 14 is also typically 0.1 to 2.0 mm, for example, 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.3 mm, 1.5 mm, 1.7 mm, 2.0 mm, or other values ​​between 0.1 and 2.0 mm.

[0031] It should be noted that both the first support plate 11 and the second support plate 14 can be formed by stacking multiple layers of carbon fiber composite fabric. Furthermore, the carbon fiber type of the carbon fiber composite fabric used for stacking the first support plate 11 and the second support plate 14 can be independently selected from any one of T300, T400, T600, T700, T800, T1000, and T1200. Moreover, the carbon fiber mass fraction in the carbon fiber composite fabric can be 58% to 67%, for example, 58%, 60%, 63%, 67%, etc. The layup angle of each layer of carbon fiber composite fabric can be set according to specific requirements, such as 0 degrees, 30 degrees, 45 degrees, 60 degrees, and 90 degrees. Specifically, the layup angle of the carbon fiber composite fabric is the angle between the warp or weft yarn of the carbon fiber composite fabric and the direction from the heel to the forefoot.

[0032] The thickness of each layer of carbon fiber composite fabric can be 0.10 to 0.15 mm. The type of resin in the carbon fiber composite fabric can be one or more of epoxy resin (EP), thermoplastic polyurethane (TPU), polycarbonate (PC), nylon (PA), polyether ether ketone (PEEK), and polyether ketone ketone (PEKK). The mass fraction of the resin can be 33% to 42%.

[0033] In practical applications, to ensure that the stiffness of the second support plate 14 is greater than that of the first support plate 11, a carbon fiber composite fabric with greater stiffness can be used to stack and lay the second support plate 14, or more layers of carbon fiber composite fabric can be used to stack and lay the second support plate 14. For example, the same carbon fiber composite fabric can be used to stack and lay the first support plate 11 and the second support plate 14, but the number of stacked layers of carbon fiber composite fabric in the second support plate 14 is greater than the number of stacked layers of carbon fiber composite fabric in the first support plate 11.

[0034] For example, the first support plate 11 includes 10 layers of stacked carbon fiber composite fabric, while the second support plate 14 includes 13 layers of stacked carbon fiber composite fabric, making the stiffness of the second support plate 14 greater than that of the first support plate 11.

[0035] For the 10 layers of carbon fiber composite fabric stacked in the first support plate 11, the layup angle of any or designated 4 layers of carbon fiber composite fabric can be 0 to 10 degrees (e.g., 0 degrees, 5 degrees), the layup angle of any or designated 2 other layers of carbon fiber composite fabric is 50 to 70 degrees (e.g., 60 degrees, 65 degrees), and the layup angle of the remaining 4 layers of carbon fiber composite fabric is 80 to 100 degrees (e.g., 90 degrees, 95 degrees).

[0036] For the 13 layers of carbon fiber composite fabric stacked in the second support plate 14, the layup angle of any or specified 6 layers of carbon fiber composite fabric is 0 to 10 degrees (e.g., 0 degrees, 5 degrees), the layup angle of any or specified 2 layers of carbon fiber composite fabric is 20 to 40 degrees (e.g., 30 degrees, 35 degrees), and the layup angle of the remaining 5 layers of carbon fiber composite fabric is 80 to 100 degrees (e.g., 90 degrees, 95 degrees).

[0037] The first support frame 13 in the elastic device 10 is disposed between the lower surface of the first support plate 11 and the upper surface of the second support plate 14, and the rigid support part 12 is embedded in the first support frame 13, thereby stabilizing the rigid support part 12 and playing a buffering role through the first support frame 13. The structure of the first support frame 13 can typically be a ring, circle, rectangle, square, trapezoid, parallelogram, or other irregularly shaped support bar.

[0038] In practical applications, foamed materials are typically used to make the first support frame 13. The foamed material can be one or more of the following: nylon elastomer (Peba), polyurethane (PU, thermoplastic polyurethane, cast polyurethane, compounded polyurethane), thermoplastic polyester elastomer (TPU), ethylene-octene copolymer (POE), ethylene-octene block copolymer (OBC), ethylene-vinyl acetate copolymer (EVA), styrene-butadiene block copolymer (SBS), hydrogenated styrene-butadiene block copolymer (SEBS), high styrene rubber, brominated butyl rubber (BIIR), cis-butadiene rubber (BR), silicone rubber, ethylene propylene diene monomer (EPDM), natural rubber (NR), and nitrile rubber (NBR).

[0039] The rigid support portion 12 in the elastic device 10 can be a rigid support sheet, a rigid support block, or multiple rigid support strips arranged in a cross pattern. For example, in Figure 1 In this design, the rigid support portion 12 is composed of two cross-shaped rigid support strips. As a force transmission component, the rigid support portion 12 concentrates the stress of the first support plate 11 in the area corresponding to the rigid support portion 12 and transmits it to the second support plate 14. Furthermore, the material of the rigid support portion 12 can be any one or more of polyethylene (PE), polypropylene (PP), nylon (PA), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), PLA (polylactic acid), polymethyl methacrylate (PMMA), polyetheretherketone (PEEK), and polyetherketoneketone (PEKK).

[0040] The second support frame 15 is disposed on the lower surface of the second support plate (14), and the hardness of the second support frame 15 is greater than that of the first support frame 13, thereby providing overall support at the bottom and providing sufficient deformation space for the upper structure. The shape of the second support frame 15 can be basically the same as that of the first support frame 13, and its material can be any one or more of PE, PP, PA, PC, ABS, PLA, PMMA, PEEK, and PEKK.

[0041] The sole provided in this embodiment includes an elastic device 10, comprising a first support plate 11, a rigid support portion 12, a first support frame 13, a second support plate 14, and a second support frame 15. The first support frame 13 is disposed between the lower surface of the first support plate 11 and the upper surface of the second support plate 14. The rigid support portion 12 is embedded within the first support frame 13, and the second support frame 15 is disposed on the lower surface of the second support plate 14. This allows for greater kinetic energy to be provided by the rebound of the two support plates during exercise when the first support plate 11 and the second support frame 15 undergo elastic deformation. This improves the user's vertical jump height, starting speed, and agility, thus enhancing the quality of the shoe. Furthermore, unlike existing technologies that use springs or similar spring structures in the sole to provide rebound kinetic energy, this application provides kinetic energy through the rebound of the first and second support plates. Compared to springs or similar spring structures, this provides greater stability due to the larger force-bearing area.

[0042] In particular, when both the first support plate 11 and the second support plate 14 are made of multiple layers of carbon fiber composite fabric laid in a stacked manner, the high elastic modulus of the carbon fiber composite fabric allows for minimal deformation of the sole during movement, and also provides greater kinetic energy through the rebound of the first support plate 11 and the second support plate 14.

[0043] Based on the same inventive concept, embodiments of this application can also provide a shoe. For example... Figure 2 As shown, the sole of the shoe uses the sole 1 provided in the embodiment of this application, which includes an elastic device 10. The elastic device 10 is disposed in the forefoot area of ​​the sole 1, etc. The elastic device 10 includes a first support plate 11, a rigid support part 12, a first support frame 13, a second support plate 14, and a second support frame 15. Therefore, this shoe can also solve the problems in the prior art, which will not be described in detail here.

[0044] To better illustrate the technical effects of the shoe sole (shoe) provided in the embodiments of this application, corresponding examples will be provided in conjunction with actual scenarios.

[0045] In this example, the elastic device 10 is provided in the forefoot area of ​​the sole, and the structure of the elastic device 10 is as follows: Figure 1 As shown.

[0046] Based on this, the present application provides a shoe sole that can solve the above-mentioned technical problems. The shoe sole includes an elastic device 10, which is typically located in the forefoot area of ​​the sole.

[0047] Both the first support plate 11 and the second support plate 14 are constructed by stacking multiple layers of carbon fiber composite fabric. The carbon fiber composite fabric is of type T700, unidirectional, with a carbon fiber mass fraction of 67%, and the resin is epoxy resin with a mass fraction of 33%. Each layer of carbon fiber composite fabric is 0.10 mm thick. The first support plate 11 is 1.0 mm thick and is constructed by stacking 10 layers of carbon fiber composite fabric. The second support plate 14 is 1.3 mm thick and is constructed by stacking 13 layers of carbon fiber composite fabric.

[0048] Furthermore, for the 10 layers of carbon fiber composite fabric stacked in the first support plate 11, the layup angle of any 4 layers of carbon fiber composite fabric can be 0 degrees, the layup angle of any 2 other layers of carbon fiber composite fabric is 60 degrees, and the layup angle of the remaining 4 layers of carbon fiber composite fabric is 90 degrees. For the 13 layers of carbon fiber composite fabric stacked in the second support plate 14, the layup angle of any 6 layers of carbon fiber composite fabric is 0 degrees, the layup angle of any 2 other layers of carbon fiber composite fabric is 30 degrees, and the layup angle of the remaining 5 layers of carbon fiber composite fabric is 90 degrees.

[0049] The rigid support part 12 consists of two cross-shaped rigid support strips made of nylon with a hardness (Shore D) of 70. The wall thickness of the annular support strip is 2mm, and its length, width, and height are as follows:

[0050] 50mm*40mm*3mm.

[0051] The first support frame 13 is made of Peba foam elastomer with a hardness (Shore C) of 45 and a density of 0.11 g / cm3.

[0052] The second support frame 15 is made of nylon material with a hardness (Shore D) of 70. The wall thickness of the annular support strip is 4mm, and the length, width and height are 140mm*90mm*7mm respectively.

[0053] The elastic device 10 comprises a first support plate 11, a rigid support part 12, a first support frame 13, a second support plate 14, and a second support frame 15 bonded together with adhesive. The mechanical properties of the elastic device 10 were tested using a universal testing machine. The test conditions were as follows: total compression deformation of 5 mm, compression loading and unloading rate of 0.05 mm / s, and the average stress value of different test areas with a 5 mm deformation was 1757 ± 206 N.

[0054] Furthermore, the elastic device 10 was placed in the forefoot area of ​​the sole of the shoe, and four subjects were randomly selected to conduct a biomechanical vertical jump height test with the maximum extension force of the two feet within the force value of the device.

[0055] Subject 1, weighing 669N (68.3kg), had a maximum vertical extension force of 1579N when jumping with both feet.
