Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a support component for increasing sole support, and a sole and a shoe comprising the structure. Background Art

[0002] The annual report of the Chinese Athletics Association also shows that the number of marathon events in China continues to grow throughout the year, with 7.12 million participants. In the past few decades, the number of runners around the world has been growing exponentially. Although running has many health benefits, long-distance running injuries are common, with the incidence of lower limb running injuries as high as 19.4%-79.3%. And long-distance running puts a lot of pressure on the feet, which may cause changes in plantar pressure and foot morphology. The height of the navicular bone drops by 5mm after a half marathon, and the height of the navicular bone drops by 4.8mm one day after a full marathon. The drop of the navicular bone will cause instability in the core system of the foot. Instability in the core of the foot will lead to incorrect movement patterns, which will cause damage or injury and affect sports performance. The arch of the foot is an important structure of the human foot. Its functions include supporting body weight, buffering shock, and adjusting balance. Changes in the deformation of the arch of the foot over long distances will lead to a decrease in the buffering capacity of the foot, uneven force on the foot, greater force on the medial side than on the lateral side, excessive pronation, increased torsional force on the knee, and increased risk of injury. Changes in foot posture are a key factor in several running injuries, so maintaining the overall structure and shape of the arch is the most effective scientific way to reduce injuries and improve performance.

[0003] However, most of the existing shoe technology solutions have the following common problems: (1) At present, major sports brands pay more attention to forefoot propulsion in the development of racing running shoes. They adjust the forefoot lever fulcrum and the ankle and metatarsophalangeal joint force arms by embedding carbon plates in the midsole, and superimpose high-elastic midsole materials to improve the performance of racing running shoes. Most of them ignore the arch support design, not only because of the lack of insight into the changes in the foot in long-distance events, but also because of the consideration of lightweight racing shoes. (2) In addition to normal feet, runners participating in marathon events also have flat feet and high arches. In the racing running shoes on the market that focus on arch support, there is a phenomenon of arch pushing, and the adaptability is not high. In summary, for elite runners, while improving the forefoot propulsion, paying attention to the changes in foot posture and foot pressure after long distances plays a key role in improving performance and reducing the risk of sports injuries.

[0004] Therefore, it is necessary to design a structure that provides long-distance arch support, which can maintain excellent forefoot propulsion while providing arch support to avoid the problem of plantar stress concentration after the foot posture and foot pressure of marathon runners change during long-distance competitions.

[0041] In order to better understand the purpose, structure and function of the present invention, a support member, a sole and a shoe for increasing plantar support provided by the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] like Figure 1 and Figure 2As shown, the support member includes a first area 1, a second area 2 and a third area 3 which are arranged in sequence from the toe to the heel. The first area 1 is a plurality of first free ends that converge toward the intersection of the second area 2, corresponding to the forefoot part of the human foot; the center of gravity of the second area 2 is located on the inner side of the midline of the sole in the transverse direction, corresponding to the midfoot part of the human body; the center of gravity of the third area 3 is located on the inner side of the center in the transverse direction of the sole, corresponding to the heel of the human body, and the end away from the first area corresponds to the side wall of the shoe and extends upward; the second area 2 and the third area 3 respectively provide support to the inner side of the mid-waist and the inner side of the heel of the human foot to compensate for the work done by the flexor hallucis longus and the flexor toes longus, thereby alleviating muscle stiffness after long-term exercise.

[0043] Specifically, Figures 2 to 8 As shown, the support member is arranged by fitting the shape of the flexor hallucis longus tendon 5 and the flexor digitorum longus tendon 4 of the human foot. The first area 1 includes a long strip-shaped first support portion 11, a second support portion 12, a third support portion 13, a fourth support portion 14, and a fifth support portion 15 arranged from the toe to the midfoot, respectively corresponding to the first toe, the second toe, the third toe, the fourth toe and the fifth toe from the inside to the outside of the human foot. The support portions extend along the paths of the phalanges and metatarsal bones of the human foot and then concentrate toward the second area 2 corresponding to the inside of the midfoot of the human body, providing upward support for the forefoot of the human body, wherein the second support portion 12, the third support portion 13, the fourth support portion 14, and the fifth support portion 15 intersect at a first gathering point 16 at a position close to the second area 2, and the first gathering point 16 corresponds to the gathering point of the flexor digitorum longus tendons 4 of the second toe, the third toe, the fourth toe and the fifth toe of the human foot, thereby conforming to ergonomic biomechanics to improve the accuracy of the support force of the first area 1 on the second toe to the fifth toe in the forefoot area of ​​the human body. The supporting member may be in the shape of a sheet, a stick or other similar shapes, as long as it is a strip structure that can conform to the extension path of the metatarsal bones and phalanges of the human body.

[0044] like Figure 3 As shown, the middle portion of the support member is bent vertically downward to form an arched concave structure 17, and the direction of the tangent line formed by the concave structure 17 and the horizontal plane is directed from the inner side of the sole to the outer side of the sole, thereby forming an arc-shaped storage space between the first area 1 and the horizontal plane to accommodate the physiological arc generated when the phalanges and metatarsal joints of the human foot are flexed, thereby reducing the pressure on the forefoot area of ​​the human foot during the extension stage.

[0045] The second area 2 includes a sixth support portion 21 and a first collection area 22, and a second collection area 23, which are arranged in sequence from the toe to the heel, corresponding to the cuneiform, navicular and talus parts of the human foot. The thickness of the second area 2 is 1mm to 2mm, and has a curvature that conforms to the upward arch of the human foot, thereby increasing the rigidity of the inner side of the mid-waist, improving the support and anti-torsion rigidity of the inner side of the waist. Preferably, the rigidity of the second area 2 is greater than or equal to the rigidity of the first area 1, so that the supporting force of the second area 2 on the midfoot area is greater than or equal to the supporting force of the first area 1 on the forefoot area, so as to reduce the pressure on the forefoot area during the extension phase and provide sufficient support to the mid-waist area.

[0046] Specifically, the sixth support portion 21 in the second area 2 is the portion of the first support portion in the first area 1 extending to the second area 2, and the first gathering area 22 is an inverted triangle area formed by further intersecting after the four support members intersect at the first gathering point 16. The sixth support portion 21 and the first gathering area 22 extend toward the heel and intersect at the second gathering point 24, and then further extend to form an inverted triangle second gathering area 23. The first support portion 11 and the sixth support portion 21 are correspondingly arranged at the position of the flexor hallucis longus tendon 5 of the human foot, and the second gathering point 24 is correspondingly arranged at the intersection of the flexor hallucis longus tendon 5 and the flexor digitorum longus tendon 4 of the human foot. Therefore, the second area 2 is arranged biased towards the inner side of the midfoot, providing an upward support force that conforms to ergonomic biomechanics, especially improving the accuracy of the support force on the inner side of the midfoot.

[0047] Of course, the relative position relationship and distance between the first assembly point 16 and the second assembly point 24, and the first assembly area 22 and the second assembly area 23 in the present embodiment are only preferred schemes, and the relative position or distance between the first assembly point 16 and the second assembly point 24, and the first assembly area 22 and the second assembly area 23 can also be expanded as needed. For example, the first assembly point 16 and the second assembly point 24 are overlapped, and the first assembly area 22 and the second assembly area 23 are overlapped, that is, the first support part 11, the second support part 12, the third support part 13, the fourth support part 14, and the fifth support part 15 converge at an intersection, which can also achieve a certain effect of enhancing the support force of the medial side of the human midfoot.

[0048] The third area 3 includes a seventh support portion 31 and an eighth support portion 32, and the seventh support portion 31 and the eighth support portion 32 are arranged along the midfoot pointing to the sole direction, and are arranged to be separated from each other through the intersection point of the second area, and the end away from the first area is the second free end, which corresponds to the calcaneal part of the human foot and extends upward along the side wall of the shoe, and the second free end is located between the vertical line of the ankle joint of the human foot and the inner surface of the side wall. The length from the second free end to the vertical line of the ankle joint of the human foot is the first distance, and the first distance is set to 1mm~2mm. The length from the second free end to the inner surface of the side wall is the second distance, and the second distance is set to 1mm~2mm, so as to reduce the deformation of the midsole material on the inner side of the heel, and slow down the increase in pressure on the inner side of the heel after long-distance exercise to produce excessive pronation, that is, increase the upward and forward rigid support of the inner side of the heel of the sole, increase the overall support of the inner side, thereby effectively reducing the change of plantar pressure after long-distance running, and reducing the risk of rearfoot eversion.

[0049] Specifically, the seventh support portion 31 is the portion of the sixth support portion 21 in the second area 2 extending toward the heel direction to the third area 3, and is arranged corresponding to the flexor hallucis longus tendon 5 of the human foot. The eighth support portion 32 is the portion of the second gathering area 23 extending toward the heel direction to the third area 3, and is arranged corresponding to the flexor digitorum longus tendon 4 of the human foot. The seventh support portion 31 and the eighth support portion 32 are the sixth support portion 21 and the first gathering area 22 extended in a separated position relationship after being merged through the second gathering area 23. By arranging the third area 3 according to the positional relationship where the flexor hallucis longus and flexor digitorum longus tendons 4 of the human body intersect and then are separated again, an upward supporting force that conforms to ergonomic biomechanics is provided, especially the accuracy of the support force on the heel position of the foot is improved.

[0050] Preferably, the above support member adopts an integrally formed structure, which increases the efficiency and continuity of the transmission of the supporting force from the heel to the forefoot area of ​​the human foot while ensuring the performance of the human foot in the extension phase.

[0051] During current long-distance running competitions, athletes experience high mechanical stress due to various muscle fiber injuries, metabolic disorders, muscle fatigue, and changes in muscle stiffness and elasticity. From a physiological point of view, muscle stiffness is largely determined by the size and structure of the muscle and its specific structural function. The physiological cross-sectional area (PCSA) is considered to be one of the basic characteristics that determine muscle stiffness.

[0052] Foot muscles such as the flexor hallucis longus and flexor digitorum longus Figure 5 and Figure 8As shown, the long flexor muscles originate from the calf through the ankle and metatarsophalangeal joint, insert into the distal phalanges, and functionally realize plantar flexion of the foot and toes. The long flexor muscles account for nearly 10% of the physiological cross-sectional area of ​​all calf muscles. Athletes use the plantar in this program for experimental training. After a few weeks, the long flexor muscles respond strongly to the increase in load. The increase in strength potential helps to improve the athletes' performance. The long flexor muscles can provide power for the athletes' forward leaning movements. Typical forward leaning occurs not only in horizontal jumps, but also in sprint starts and cut-in movements (stride gain). By using the above-mentioned support structure to compensate for muscle work, muscle stiffness after long-distance events can be alleviated.

[0053] like Fig. 9 As shown in the figure, based on the force characteristics of long-distance running spikes in the extension phase, the pressure of spike C is the largest, followed by spike D, and the force is applied to the inner side of the forefoot. Spikes A, F and G play a certain supporting role. The pressure of spikes B, E and H are all small and have little effect on extension. The area where spike D is located corresponds to the middle of the second metatarsal and the third metatarsal of the human foot and is biased towards the second metatarsal, which has a strengthening effect on extension. The first phalanx, the first and second metatarsal bones bear greater pressure than other parts. The extension phase is accompanied by a certain degree of internal rotation. The first metatarsal corresponding to the thumb bears the most force. Increasing the extension torque of the thumb is beneficial to improving sports performance. Therefore, the stiffness function requirements of the forefoot area are the first metatarsal> the third metatarsal> the second metatarsal area> the fourth and fifth metatarsal areas. Combined with increasing the extension torque of the thumb, it is beneficial to improve running performance.

[0054] Preferably, the thicknesses of the first support portion 11, the second support portion 12, the third support portion 13, the fourth support portion 14 and the fifth support portion 15 in the first area 1 of the embodiment of the utility model are respectively set to the first thickness, the second thickness, the third thickness, the fourth thickness and the fifth thickness, wherein the first thickness is greater than the third thickness, the third thickness is greater than the second thickness, the second thickness is greater than the fourth thickness, and the second thickness is greater than the fifth thickness. Specifically, by setting different thicknesses of support members, corresponding rigid support is provided to different pressure distribution areas in the forefoot area during the extension phase of the human foot, that is, corresponding supporting force is provided, thereby improving the supporting effect while ensuring the buffering capacity.

[0055] Of course, in some other implementations, the proportional relationship between the thicknesses may also be adjusted, that is, as long as a support member is formed in the forefoot area of ​​a human foot, a certain effect of improving the forefoot support force may be achieved.

[0056] Specifically, after long-distance running, the pressure pattern of the human foot changes, the load on the inner side of the heel, midfoot and metatarsal bones increases, and the load on the outer side of the toes decreases, which will increase the risk of rearfoot eversion. The first thickness is set to 5mm-7mm, the third thickness is set to 4mm-6mm, the second thickness is set to 3mm-5mm, and the fourth and fifth thicknesses are set to 2mm-4mm. The gradient setting of this thickness range conforms to the rigidity requirement of the forefoot area of ​​the human foot when the human body runs fast. By making the inner side rigidity of the support component greater than the outer side rigidity, greater upward support force is provided to the inner side of the heel, midfoot, first metatarsal and third metatarsal bones, reducing the load on the inner side of the sole to balance the pressure distribution of the human foot, especially increasing the dynamic support on the inner side of the sole, thereby reducing the risk of foot eversion and improving overall athletic performance.

[0057] The utility model also discloses a sole, such as Figures 10 to 12 As shown, the sole includes an elastic layer and the above-mentioned supporting member for increasing the support of the sole.

[0058] The elastic layer and the support member are stacked to form a sole body. The sole body may include one elastic layer or two or more elastic layers; or the sole body may include one support member or two or more support members. The two or more elastic layers and the support member are staggered and overlapped to form a sole body with good resilience and shock absorption, and can effectively support the sole body.

[0059] like Fig.12 As shown in the figure, as a preferred embodiment of the utility model, the sole includes a first elastic layer 6, a support member and a second elastic layer 7 stacked in sequence from top to bottom. The first elastic layer 6 and the second elastic layer 7 are made of elastic material, which can provide excellent shock absorption and rebound effects for the sole of the human foot during running.

[0060] The first elastic layer 6 includes a forefoot area, a mid-waist area and a heel area which are arranged in sequence from the toe to the heel, and are arranged corresponding to the first area 1, the second area 2 and the third area 3 in the support member respectively. Connecting grooves are arranged in the forefoot area, the mid-waist area and the heel area, and the connecting grooves correspond to the structure of the support member so that the support member can be embedded in the connecting grooves. The support member and the first elastic layer 6 are better connected and the curvature of the first elastic layer 6 conforms to the curvature of the hard support member, which is beneficial to keep the material morphology deformation consistent during the extension stage of the human foot, improves the comfort of repetitive motion (running) and the smoothness of force transmission, and also reduces the risk of the first elastic layer 6 and the second elastic layer 7 being cut by the hard support member.

[0061] The sole also includes an outsole 8, which is arranged below the second elastic layer 7. It uses a material that has excellent anti-slip properties and fatigue wear resistance. The thickness of the outsole 8 is reduced to the thinnest to meet the actual running sports needs, effectively reduce the thickness and weight of the sole, achieve the functional effect of lightweight shoes, and provide the wearer with a better wearing experience.
