Description

Technical Field

[0001] This utility model relates to the field of footwear, and more particularly to an arch support component and a sole containing the arch support component. Background Technology

[0002] The human foot arch can be divided into the transverse arch and the longitudinal arch, with the longitudinal arch further divided into the medial and lateral longitudinal arches. The medial longitudinal arch is higher and more elastic, exhibiting greater deformation during running and serving as the primary cushioning structure. The lateral longitudinal arch, on the other hand, is lower and less elastic, primarily providing stability. During running, the foot arch undergoes repeated lengthening and shortening, as well as pronation. Over cyclical runs of tens of kilometers, this can lead to arch collapse, reducing athletic performance and increasing the risk of injury.

[0003] While carbon-plated running shoes can improve athletic performance, studies have shown that the incidence of running-related injuries has not decreased with their introduction. The overall incidence rate is 40.2%, with the highest rates of injuries affecting the knee, ankle, and lower leg. The overall prevalence of running-related diseases is 44.6%, with the highest rates also found in the knee, lower leg, and foot.

[0004] Therefore, existing athletic shoes increase stability during landing by increasing the width of the sole and distributing pressure on the sole, and limit the range of motion of the foot by adding TPU hardware in the midfoot or heel. However, for runners who are heavier, have wider feet, or have weaker ankles, existing technologies have drawbacks such as poor upper support comfort, insufficient sole cushioning, and poor foot stability during running. Utility Model Content

[0005] The purpose of this invention is to provide an arch support component and a shoe sole containing the arch support component. By setting a split support component, a top-down, step-by-step reverse support mechanism is formed, improving the overall stability and comfort of the support. The specific technical solution is as follows:

[0006] An arch support component includes a first component and a second component that are separately disposed. The first component is disposed close to the arch of the foot, and the second component is disposed below the first component. The first component includes a first inner portion and a first outer portion that are connected together. The second component includes a second inner portion that is disposed corresponding to the first inner portion and a second outer portion that is disposed corresponding to the first outer portion. Both the first outer portion and the second inner portion protrude in the direction of the arch of the foot to support the outer and inner sides of the arch of the foot, respectively.

[0007] Furthermore, the first outer part gradually curves upward in the direction from the inside to the outside.

[0008] Furthermore, the first outer portion extends longitudinally and is positioned on the outer side of the arch of the foot, while one end of the first inner portion corresponds to the inner side of the arch of the foot and the other end is connected to the middle of the first outer portion.

[0009] Furthermore, the second inner part extends longitudinally and gradually curves upward in the direction from the toe to the heel.

[0010] Furthermore, the second component also includes a connecting portion, one end of which is connected to the second inner portion and the other end of which is connected to the second outer portion. The second outer portion extends in the longitudinal direction, and the second inner portion, the connecting portion, and the second outer portion together form a first groove, the opening of which faces the heel.

[0011] Furthermore, the length of the second outer portion is greater than the length of the second inner portion, one end of the connecting portion is connected to the end of the second inner portion near the toe, and the other end of the connecting portion is connected to the side of the second outer portion near the toe.

[0012] Furthermore, a space is formed between the first component and the second component, and the space is used to fill the elastic layer.

[0013] Furthermore, the first inner portion and the first outer portion are configured as an integrally formed structure; and / or, the second inner portion, the connecting portion, and the second outer portion are configured as an integrally formed structure.

[0014] A shoe sole includes a second elastic layer and the arch support component described above, wherein the second elastic layer is disposed between the first component and the second component.

[0015] Furthermore, a second groove is formed on the arch area of ​​the second elastic layer, the opening of the second groove faces the outside of the sole, the second groove is correspondingly provided with the first component, and the second groove is correspondingly provided with the second component.

[0016] Furthermore, the first outer portion is provided correspondingly to the second groove, and the second outer portion is provided correspondingly to the second groove.

[0017] Furthermore, the first groove and the second groove are provided in a corresponding manner.

[0018] Furthermore, it also includes a first elastic layer, which is disposed on the side of the first component near the arch of the foot. The first elastic layer includes a forefoot portion and a heel portion, and a cushioning zone is provided on the forefoot portion and / or the heel portion.

[0019] The arch support component of this invention, and the sole containing the arch support component, have the following advantages:

[0020] 1. By setting up a split arch support component, a support structure with height difference between the inner and outer sides of the arch is provided. When people with larger weight, wider feet, or weaker ankle strength run, the pressure is transmitted downward from the sole of the foot. The pressure of the outer longitudinal arch is borne and partially dispersed by the first outer part of the first component, while the pressure of the inner longitudinal arch is transmitted through the first inner part to the second inner part below. Then, the protruding structure of the inner part applies a reaction force upward, forming a lifting effect. This achieves a reverse support mechanism that transmits the pressure from top to bottom in stages, improving the overall stability and comfort of the support.

[0021] 2. A gap is formed between the first component and the second component, which in turn forms a barrier between the first component and the second component, allowing the first component and the second component to respond to changes in foot pressure relatively independently, avoiding rigid conflict caused by direct contact between the two, improving the stability of the support, and the gap provides a buffer margin for foot movement, thereby avoiding discomfort caused by excessive rigidity and improving the comfort of the shoe.

[0022] 3. The first outer part gradually curves upward from the inside to the outside, forming a support structure that fits the outer longitudinal arch better. The load on the outer longitudinal arch is gradually transferred to the second component through the space, reducing the direct pressure on the foot and improving comfort.

[0023] 4. The second inner side provides progressive support, conforming to the natural curvature of the inner longitudinal arch, reducing direct pressure on the foot, while improving the support efficiency of deep muscles, thus enhancing support stability and comfort.

[0024] 5. The second inner part, the connecting part, and the second outer part enclose and form the first groove, which effectively reduces the support rigidity of the middle of the arch, realizes the dynamic distribution of pressure on the sole of the foot, and enhances the stability and comfort of the foot.

[0039] To better understand the purpose, structure, and function of this utility model, the arch support component and the sole containing the arch support component of this utility model will be described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, the arch support component of this utility model is a split structure comprising two independent components. The component is disposed inside the sole of the shoe, corresponding to the arch of the human foot. Specifically, it includes a first component 100 disposed near the arch and a second component 200 disposed away from the arch, that is, the first component 100 is disposed above the second component 200.

[0041] like Figures 2 to 8As shown, the side closer to the inside of the foot is defined as the inside of the arch support component and the sole, and the side closer to the outside of the foot is defined as the outside of the arch support component and the sole. The first component 100 includes a first inner part 101 and a first outer part 102 connected together. The second component 200 includes a second inner part 201 and a second outer part 202 disposed opposite to each other. The second inner part 201 is disposed below the first inner part 101, and the second outer part 202 is disposed below the first outer part 102. The first outer part 102 protrudes towards the direction of the arch relative to the first inner part 101 to provide support for the outer side of the human arch. The second inner part 201 protrudes towards the direction of the arch relative to the second outer part 202 to provide support for the inner side of the human arch.

[0042] The purpose of the above structure is to support the lateral and medial longitudinal arches of the foot respectively through the coordinated operation of the first component 100 and the second component 200, effectively limiting the extent of arch collapse during running. The first lateral part 102 of the first component 100 is closer to the lateral longitudinal arch and can directly conform to the arch, making it suitable for shaping and providing light support to the lateral longitudinal arch, avoiding nerve compression or discomfort. The second medial part 201 of the second component 200 is slightly further away from the medial longitudinal arch, that is, it is set deeper in the sole than the first lateral part 102, thus providing greater rigidity and deeper reaction force, making it more suitable as a support structure for the medial longitudinal arch and effectively resisting collapse.

[0043] It is important to emphasize that by setting up a split arch support component, a support structure with a height difference between the inner and outer sides of the arch is provided. When people with greater weight, wider feet, or weaker ankle strength run, the pressure is transmitted downwards from the sole of the foot. The pressure on the outer longitudinal arch is received and partially dispersed by the first outer part 102 of the first component 100, while the pressure on the inner longitudinal arch is transmitted through the first inner part 101 to the lower second inner part 201, and then the protruding structure of the second inner part 201 applies a reaction force upwards, creating a lifting effect. This top-down, step-by-step reverse support mechanism improves the overall stability and comfort of the support.

[0044] It is understandable that the first component 100 and the second component 200 are independent, separate structures, positioned vertically in a corresponding manner. Furthermore, a space is formed between the first component 100 and the second component 200, creating a barrier that allows each component to respond relatively independently to changes in foot pressure, avoiding rigidity conflicts caused by direct contact and improving support stability. In addition, the space provides cushioning allowance for foot movement, allowing the foot to naturally sink and rebound during dynamic activities such as running and jumping. When the arch of the foot is impacted, the first component 100 can compress slightly, while the second component 200 does not immediately intervene due to the space, thus avoiding discomfort caused by excessive rigidity and improving shoe comfort.

[0045] Specifically, the end near the toe is defined as the front side of the arch support component and the sole, the end near the heel is defined as the rear side of the arch support component and the sole, the line connecting the front and rear sides is defined as the longitudinal direction, and the line connecting the inner and outer sides is defined as the transverse direction. The first outer part 102 extends in the longitudinal direction and corresponds to the outer side of the arch to evenly distribute pressure, avoid local stress concentration on the outer longitudinal arch, prevent arch eversion, and improve support stability.

[0046] Furthermore, the first outer part 102 gradually moves away from the second outer part 202 in the direction from the inside to the outside, that is, the first outer part 102 gradually curves upward from the inside to the outside. This structure forms a support structure that fits the outer longitudinal arch better, and the load on the outer longitudinal arch is gradually transmitted to the second component 200 through the space, reducing the direct pressure on the foot and improving comfort.

[0047] Furthermore, the first inner side portion 101 extends laterally, with one end corresponding to the inner side of the arch and the other end connected to the middle position of the first outer side portion 102. That is, the front and rear ends of the first outer side portion 102 protrude from the first inner side portion 101. By extending laterally, it covers the entire inner arch area and conforms to the inner contour of the sole, preventing the arch from collapsing. At the same time, the first inner side portion 101 forms a lateral pressure transmission path by connecting to the middle position of the first outer side portion 102, transmitting the rigid support force of the inner longitudinal arch to the dynamic support structure of the outer longitudinal arch, achieving a synergistic effect of inner and outer support and improving the stability of the support.

[0048] Preferably, the second inner portion 201 extends longitudinally, forming a cross-support structure with the laterally extending first inner portion 101, covering the entire force path of the medial longitudinal arch. This combines longitudinal rigid support with lateral stability constraint, effectively suppressing medial longitudinal arch collapse caused by foot pronation. Simultaneously, the second inner portion 201 gradually approaches the first inner portion 101 along the direction from the toe to the heel, creating a progressive support effect. This means the support strength gradually increases from the toe to the heel, conforming to the natural curvature of the medial longitudinal arch, which is highest at the heel and gradually decreases towards the toe. This reduces direct pressure on the foot while improving the support efficiency of deep muscles, enhancing support stability and comfort. The second outer portion 202 is positioned more horizontally than the second inner portion 201 to improve the smoothness of the transition from heel to forefoot during running, as well as enhance midfoot support and stability.

[0049] Preferred, such as Figures 5 to 8 As shown, the second component 200 also includes a connecting portion 203. One end of the connecting portion 203 is connected to the second inner side portion 201, and the other end is connected to the second outer side portion 202. That is, the connecting portion 203 connects the second inner side portion 201 and the second outer side portion 202, forming a bridge-like structure. By transmitting pressure laterally, the support forces of the inner and outer sides are coordinated, avoiding support blind spots and improving overall support efficiency. At the same time, the second outer side portion 202 extends from the toe to the heel. The second inner side portion 201, the connecting portion 203, and the second outer side portion 202 enclose a first groove 204. The opening of the first groove 204 faces the heel to effectively reduce the support rigidity of the middle of the arch. Thus, by setting the connecting portion 203 of the second component 200, dynamic dispersion of pressure on the sole of the foot is achieved, enhancing the stability and comfort of the foot.

[0050] Furthermore, defining the distance between the two ends of the structure in the longitudinal direction as length, the length of the second outer portion 202 is greater than the length of the second inner portion 201. The relatively longer second outer portion 202 can cover more of the outer foot area, providing a greater range of support, while the shorter second inner portion 201 can avoid excessive rigid support and retain the natural elastic deformation capacity of the inner side of the foot. At the same time, one end of the connecting portion 203 is connected to the end of the second inner portion 201 near the toe, and the other end of the connecting portion 203 is connected to the side of the second outer portion 202 near the toe, so as to quickly transmit the support force of the inner and outer sides to the area near the toe through rigid connection, avoid excessive pronation of the foot due to impact force, maintain the neutral position of the lower limb force line, and improve the stability of support.

[0051] Furthermore, the first inner portion 101 and the first outer portion 102 are configured as an integrally molded structure to eliminate connection gaps or stress concentration points, forming a continuous rigid support structure, significantly improving the stability of the lateral longitudinal arch and lateral support, and suppressing inversion or eversion of the foot arch; the second inner portion 201, the connecting portion 203, and the second outer portion 202 are configured as an integrally molded structure to form a continuous support structure, improving the uniform transmission of plantar pressure, while also having the advantages of reducing production steps and lowering costs. Those skilled in the art can also choose to configure the first component 100 or the second component 200 as an integrally molded structure according to the actual situation.

[0052] like Figure 1 As shown, this utility model also provides a shoe sole, comprising a first elastic layer 300, a first component 100, a second elastic layer 400, a second component 200, and an outsole 500 stacked from top to bottom. The second elastic layer 400 is disposed between the first component 100 and the second component 200. In other words, the space between the first component 100 and the second component 200 is filled with the second elastic layer 400. Through the deformation capability of the second elastic layer 400, the pressure transmission path between the first component 100 and the second component 200 is connected, optimizing the dynamic balance of pressure on the medial and lateral arches, suppressing inward or outward pronation of the arch, reducing the amplitude of excessive pronation of the foot during long-distance running, and increasing running stability. In addition, the first elastic layer 300 and the second elastic layer 400 provide good shock absorption and rebound effects for the human foot. The above-mentioned stacked arrangement formed by the first component 100 and the second component 200 is beneficial to the manufacturing process and can provide the human foot with a comfortable feel and stable cushioning upon landing.

[0053] Furthermore, such as Figure 10 As shown, the second elastic layer 400 is provided for the entire sole, including the arch area. A second groove 401 is formed on the arch area. The opening of the second groove 401 faces the outside of the sole to guide part of the pressure in the arch area to the outside of the arch. It works in conjunction with the first outer part 102 and the second outer part 202 to accelerate the rebound process of the elastic material, improve the energy feedback capability, and also improve the aesthetics.

[0054] Preferably, the first groove 204 is located below the second groove 401, that is, the second groove 401 and the first groove 204 are correspondingly set at the arch position to form a local low-stiffness area, which allows the second elastic layer 400 to generate greater compression and lateral extension at this point, thereby achieving directional pressure unloading, reducing plantar fascia tension, achieving a more natural dynamic fit of the arch, and improving the stability and comfort of the arch support.

[0055] Furthermore, such as Figure 9As shown, the first elastic layer 300 is disposed on the side of the first component 100 near the arch of the foot, directly contacting the sole of the foot. The first elastic layer 300 corresponds to the entire sole, including the forefoot and heel. A cushioning zone 301 is disposed on at least one of the forefoot and heel. In this embodiment, the cushioning zone 301 includes several hexagonal honeycomb structures to increase foot comfort, improve foot feel, and enhance cushioning performance. Of course, the cushioning zone 301 can also be configured as several triangular, rhomboid, or other structures.

[0056] This utility model foot arch support component is made of rigid material, characterized by a Shore D hardness of 50-95. The rigid material is a composite material formed by at least one of the following: phenolic resin or thermoplastic resin (thermoplastic polyurethane, polycarbonate, polymethyl methacrylate, nylon elastomer, polyether ester elastomer, polyketone, polyether ether ketone, polyether ketone ketone, polyether sulfone, polyphenylene sulfide, ABS (acrylonitrile-butadiene-styrene copolymer) or inorganic fillers or long or short fibers (not limited to carbon fiber, glass fiber, aramid, ultra-high molecular weight polyethylene fiber, polyaryl ester fiber, basalt fiber, polyester fiber, etc.).

[0057] The first elastic layer 300 and the second elastic layer 400 in the sole of this invention are manufactured through supercritical foaming or chemical foaming molding processes. They are made from one, two, or more of the following materials: nylon elastomer, polyurethane (thermoplastic polyurethane (including aromatic and aliphatic types), cast polyurethane, and compounded polyurethane), thermoplastic polyether ester elastomer, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer, high-styrene rubber, brominated butyl rubber, butadiene rubber, silicone rubber, EPDM rubber, natural rubber, isoprene rubber, nitrile rubber, and chloroprene rubber. These materials have a hardness of 40-45C and a density of 0.12-0.18 g / cm³, exhibiting lightweight, soft, and elastic characteristics, providing excellent shock absorption and rebound for the foot during running.

[0058] The outsole 500 of this invention uses a material that combines slip resistance and wear resistance, meeting the actual needs of running and providing users with a good wearing experience. The outsole 500 is made of one, two, or more of the following materials: styrene-butadiene rubber, brominated butyl rubber, butadiene rubber, silicone rubber, ethylene propylene diene monomer (EPDM) rubber, natural rubber, isoprene rubber, nitrile rubber, chloroprene rubber, nylon elastomer, polyurethane (thermoplastic polyurethane (including aromatic and aliphatic types), cast polyurethane, and compounded polyurethane), thermoplastic polyether ester elastomer, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer, and high-styrene rubber.

[0059] In this embodiment, to provide optimal cushioning performance in conjunction with the arch support component, the first elastic layer 300 and the second elastic layer 400 are made of nylon elastomer material. This material has a density of 0.12-0.14 g / cm3, a Shore C hardness of 42±3, an energy return of 71.4%, and a peak acceleration of 6.8g, in order to provide a stable cushioning effect.

[0060] The first component 100 and the second component 200 are made of carbon fiber / glass fiber / epoxy resin composite material, with each layer having a thickness of 0.12 mm and a total thickness of 1.0–1.6 mm. The layup method is as follows:

[0061] (1) First layer: 3K carbon fiber twill;

[0062] (2) Second layer 45-degree carbon fiber unidirectional tape;

[0063] (3) The third layer is a 60-degree carbon fiber unidirectional tape;

[0064] (4) Fourth layer 90-degree unidirectional fiberglass tape;

[0065] (5) Fifth layer 90-degree unidirectional fiberglass tape;

[0066] (6) The sixth layer is a 60-degree carbon fiber unidirectional tape;

[0067] (7) Seventh layer 45-degree carbon fiber unidirectional tape;

[0068] (8) Eighth layer 3K carbon fiber twill.

[0069] The outsole 500 is made of cast polyurethane, which has excellent abrasion resistance. The specific properties are as follows: hardness (Shore A) is 50, density is 1.20g / cm3, tensile strength is 13.4MPa, elongation at break is 632%, right angle tear strength is 59.6N / mm, Akron abrasion (1.61km) is 0.03cm3, DIN abrasion is 11mm3, yellowing resistance is level 4, and aging resistance is level 4.

[0070] Shoes containing the sole of this embodiment were tested and compared with ordinary shoes to verify the performance of shoes containing the sole of this embodiment. Specifically, all materials of the two shoes are basically the same, the differences lie in the midsole material formula, the structure and position of the arch support component, and the outsole pattern. Multiple runners tested the biomechanical parameters of their right foot on a treadmill at the same speed, and the comparative test results are as follows:

[0071]

[0072] As the data shows, when wearing shoes with the sole of this embodiment, the work done by the human ankle and knee joints is less than that of ordinary shoes, and the abduction torque of the human knee joint is less than that of ordinary shoes. In other words, the arch support component can achieve the effect of increasing stability.

[0073] In summary, the shoe with the sole of this embodiment, by setting an arch support component, can stably support the arch of the foot during running, thereby reducing excessive pronation of the foot and increasing running stability.

[0074] The arch support component of this invention, and the sole containing the arch support component, have the following advantages:

[0075] 1. By setting up a split arch support component, a support structure with height difference between the inner and outer sides of the arch is provided. When people with larger weight, wider feet, or weaker ankle strength run, the pressure is transmitted downward from the sole of the foot. The pressure of the outer longitudinal arch is borne and partially dispersed by the first outer part of the first component, while the pressure of the inner longitudinal arch is transmitted through the first inner part to the second inner part below. Then, the protruding structure of the inner part applies a reaction force upward, forming a lifting effect. This achieves a reverse support mechanism that transmits the pressure from top to bottom in stages, improving the overall stability and comfort of the support.

[0076] 2. A gap is formed between the first component and the second component, which in turn forms a barrier between the first component and the second component, allowing the first component and the second component to respond to changes in foot pressure relatively independently, avoiding rigid conflict caused by direct contact between the two, improving the stability of the support, and the gap provides a buffer margin for foot movement, thereby avoiding discomfort caused by excessive rigidity and improving the comfort of the shoe.

[0077] 3. The first outer part gradually curves upward from the inside to the outside, forming a support structure that fits the outer longitudinal arch better. The load on the outer longitudinal arch is gradually transferred to the second component through the space, reducing the direct pressure on the foot and improving comfort.

[0078] 4. The second inner side provides progressive support, conforming to the natural curvature of the inner longitudinal arch, reducing direct pressure on the foot, while improving the support efficiency of deep muscles, thus enhancing support stability and comfort.

[0079] 5. The second inner part, the connecting part, and the second outer part enclose and form the first groove, which effectively reduces the support rigidity of the middle of the arch, realizes the dynamic distribution of pressure on the sole of the foot, and enhances the stability and comfort of the foot.
