Description

Technical Field

[0001] The invention relates to a shoe accessory and a shoe, in particular to an anti-attenuation sole and a running shoe. Background Art

[0002] The support and stability of running shoes will directly affect the user's running performance, but running shoes are usually required to have a certain rebound performance to help users save energy, which is especially important for long-distance running or high-speed running.

[0003] In order to have the above-mentioned performances at the same time, many running shoes with support plates embedded in the midsoles are currently on the market. The characteristic of this type of running shoes with support plates is that it tends to encourage users to land on the forefoot. When the body's center of gravity transitions to the forefoot, the forefoot pushes the ground to generate an oblique upward force, pushing the torso forward, so that each step can be more effectively advanced, which can reduce the contact time between the shoe and the ground, thereby improving the stride frequency and pace; however, long-term forefoot landing requires high strength in the runner's calves and ankles. In the later stages of long-term running such as marathons, the runner's metatarsophalangeal joints and ankle joints will inevitably be significantly reduced in extension efficiency, and even calf muscle cramps and strains may occur. Due to the body's own protection function, after a long period of running, runners will consciously or unconsciously move the landing point of their feet backwards, landing on the midfoot or heel, causing the propulsion assistance of the above-mentioned running shoes with support plates to gradually decay, making it difficult to continue to improve the stride frequency and pace, affecting the user's long-distance running performance, and may also cause sports injuries.

[0004] In view of this, the applicant conducted an in-depth study on the above-mentioned issues, which led to the present case. Summary of the invention

[0005] The object of the present invention is to provide an anti-attenuation sole and running shoes which are helpful to improve the long-distance running performance of the user and reduce sports injuries.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: An anti-attenuation sole comprises a shoe midsole and a support plate embedded in the shoe midsole, the support plate comprises a heel support portion, an arch support portion and a forefoot support portion which are integrally connected in sequence, upper extension pieces are integrally connected to both sides of the heel support portion in a width direction, a lower extension piece is integrally connected to one end of the upper extension piece which is not connected to the heel support portion, the lower extension piece is located below the upper extension piece, and an elastic filler is sandwiched between the upper extension piece and the upper extension piece, and the lower surface of the shoe midsole is an arc surface.

[0007] As an improvement of the present invention, the upper extension piece is arranged to be gradually tilted downward from the back to the front, and the lower extension piece is arranged to be gradually tilted downward from the front to the back.

[0008] As an improvement of the present invention, a hollow area is formed in the midsole at a position below the heel support portion.

[0009] As an improvement of the present invention, the heel support portion includes a main body section and a rear extension section integrally connected to the rear end of the main body section, the rear extension section is arranged gradually tilted upward from front to back, and each of the upper extension pieces is connected to the front end of the main body section.

[0010] As an improvement of the present invention, the distance between the rear end of the arch support part and the rear end of the midsole is 30%-35 of the length of the midsole, the distance between the front section of the arch support part and the rear end of the midsole is 55%-60% of the length of the midsole, the distance between the front end of the arch support part and the bottom surface of the midsole is 10-15mm, and the distance between the rear end of the arch support part and the bottom surface of the midsole is 30-3.5mm.

[0011] As an improvement of the present invention, the arch support portion is in an arc shape that bulges upward.

[0012] As an improvement of the present invention, the shoe midsole is a foamed midsole, the support plate is a carbon plate, and the elastic filler is a foamed material.

[0013] As an improvement of the present invention, the forefoot support portion is provided with a separation groove, which is located at a position corresponding to the gap between the first toe and the second toe of the human foot, and the separation groove is connected to the outside at the front end of the forefoot support portion.

[0014] As an improvement of the present invention, side branches are integrally connected to both sides of the forefoot support portion in the width direction, the front ends of the side branches are connected to the forefoot support portion, and the rear ends are separated from the forefoot support portion, and the side branches are located on the upper side of the forefoot support portion.

[0015] A running shoe comprises the anti-fading sole.

[0016] By adopting the above scheme, the present invention has the following beneficial effects: 1. By making the lower surface of the midsole of the shoe an arc surface and providing an upper extension piece and a lower extension piece on the rear half of the support plate, when the runner's kicking efficiency decreases and the landing point of the foot moves from the forefoot to the midfoot or heel, it can still provide a more stable support force and better propulsion assistance, which helps to improve the user's long-distance running performance and reduce sports injuries.

[0017] 2. By filling the elastic filler between the upper extension sheet and the lower extension sheet, the extension sheet can be prevented from excessive deformation or breakage. At the same time, more stable support and more sensitive rebound ability (rebound response speed) can be provided without increasing the thickness or hardness of the support plate.

[0018] 3. Since the midsole of the shoe has a hollow area below the heel support, it not only reduces the weight of the running shoe and saves running energy, but also helps to improve the pedaling efficiency, maintain the stability of the arch of the foot, and reduce sports injuries.

[0019] 4. Using the arch support to form a slope difference can provide more support for the mid-waist and heel, reduce the ground contact time, and improve the efficiency of extension and push-off. At the same time, it can reduce the twisting and deformation of the arch during running, which helps to improve stability during long-term running and reduce the risk of injury.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1 like Figure 1 and Figure 2As shown, this embodiment provides a running shoe, which includes an upper 10 and a sole 20 connected to the upper, wherein the sole 20 is an anti-attenuation sole and can be sold separately, that is, this embodiment substantially also provides an anti-attenuation sole. The specific connection structure between the upper 10 and the sole 20 is a conventional structure, which is not the focus of this embodiment and will not be described in detail here.

[0024] The sole 20 provided in this embodiment includes a midsole 21, a support plate 22 embedded in the midsole 21, and an outsole 23 covering the lower surface of the midsole 21, wherein the midsole 21 is preferably a foam midsole, the support plate 22 is preferably a carbon plate, and the outsole 23 is preferably a rubber outsole. The specific structure of the rubber outsole can be designed according to actual needs and will not be described in detail here.

[0025] For ease of explanation, in this embodiment, the side of the running shoe facing the toe is the front side of each component, and the corresponding other side is the back side; the side of the running shoe facing the ground when the running shoe is placed on a horizontal plane is the bottom side of each component, and the corresponding other side is the top side.

[0026] The support plate 22 includes a heel support portion 31, an arch support portion 32 and a forefoot support portion 33 which are integrally connected in sequence, wherein the distance between the rear end of the arch support portion 32 and the rear end of the midsole 21 is 30%-35 of the length of the midsole 21, the distance between the front section of the arch support portion 32 and the rear end of the midsole 21 is 55%-60% of the length of the midsole 21, the distance between the front end of the arch support portion 32 and the bottom surface of the midsole 21 (i.e., the lower surface of the midsole 21) is 10-15mm, and the distance between the rear end of the arch support portion 32 and the bottom surface of the midsole 21 is 30-3.5mm. In this way, the support plate 22 can form a slope difference at the arch, provide more support for the midwaist and heel, reduce the ground contact time, and improve the extension efficiency. At the same time, it can reduce the torsion and deformation of the arch during running, which helps to improve stability during long-term running and reduce the risk of injury. It should be noted that there is a smooth transition between the heel support portion 31 , the arch support portion 32 , the forefoot support portion 33 and the various pieces to be mentioned below, and there is no obvious dividing line.

[0027] Preferably, the arch support portion 32 is in an upwardly convex arc shape, which provides a better supporting effect.

[0028] The two sides of the heel support part 33 in the width direction are respectively integrally connected with an upper extension piece 34, and the end of the upper extension piece 34 not connected to the heel support part 33 (i.e., the end away from the heel support part 33) is integrally connected with a lower extension piece 35, and the lower extension piece 35 is located below the upper extension piece 34, and the upper extension piece 34 is arranged to gradually tilt downward from the back to the front, and the lower extension piece 35 is arranged to gradually tilt downward from the front to the back, and the two together form a V-shaped structure, which can form a disc spring effect, ensuring that after the user runs for a long time and causes the landing point of the foot to move from the forefoot to the midfoot or heel, it can still provide better assistance, avoid the gradual attenuation of the propulsion assistance, and at the same time avoid the attenuation of the elastic force of the sole, thereby increasing the service life.

[0029] An elastic filler 36 is sandwiched between the upper extension piece 34 and the upper extension piece 35, which can provide more stable support, and because the elastic filler 36 and the extension piece have different elastic coefficients, they can better respond to different forces. The specific material of the elastic filler and its elastic coefficient can be selected according to actual needs, such as selecting elastic rubber of a specific hardness, etc. In this embodiment, the elastic filler 36 is a foaming material, that is, the elastic filler 36 and the midsole 21 are made of the same material, and the two are connected in one piece, so that the elastic filler 36 can be filled between the upper extension piece 34 and the upper extension piece 35 during the process of foaming to form the midsole 21.

[0030] Preferably, in this embodiment, the heel support portion 31 includes a main section 41 and a rear extension section 42 integrally connected to the rear end of the main section 41, wherein the main section 41 is arranged horizontally or slightly tilted upward from the back to the front, and the rear extension section 42 is gradually tilted upward from the front to the back, so that it can cooperate with the upper, so that the upper can better cover the heel, and the support stability is also better. Each upper extension piece 34 is connected to the front end of the main section 41, and the upper extension piece 34 and the upper extension piece 35 are formed by cutting and bending on the carbon plate blank. Specifically, when producing the support plate 22, the carbon fiber layer is first used to form the blank, and then the blank is cut and bent to form the upper extension piece 34 and the upper extension piece 35, and finally the cut and bent blank is heat-set to obtain the support plate 22.

[0031] The lower surface of the midsole 21 is an arc surface, so that it can better achieve rolling during running, and form a synergistic effect with the support plate 22, helping the user to improve the running effect in the latter part of long-distance running. In addition, the midsole 21 is formed with a hollow area at the position below the heel support part 21, that is, the lower surface of the heel support part 21 is exposed to the outside, which can reduce the weight of the heel and help the user to maintain the landing point on the forefoot as long as possible when running.

[0032] Embodiment 2 like Figure 3As shown, this embodiment provides an anti-attenuation sole and running shoe, which differs from the first embodiment mainly in the structure of the forefoot support part 21. In this embodiment, the forefoot support part 21 is provided with a separation groove 37, which is located at a position corresponding to the gap between the first toe and the second toe of the human foot, and the separation groove 37 is connected to the outside at the front end of the forefoot support part 21, which helps to make the rebound effect respond faster and improve the power in the extension stage.

[0033] Embodiment 3 like Figure 4 As shown, this embodiment provides an anti-attenuation sole and running shoe, which differs from the first embodiment mainly in the structure of the forefoot support part 21. In this embodiment, the two sides of the forefoot support part 21 in the width direction are respectively connected with side branches 38, the front end of the side branches 38 is connected to the forefoot support part 21, and the rear end is separated from the forefoot support part 21, and the two side branches 38 are respectively located on the upper side of the two sides of the forefoot support part 21, so that the rebound response speed is improved and it is also helpful to relieve foot fatigue after long-term running.

[0034] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, which all belong to the protection scope of the present invention.
