Description

Technical Field

[0001] The utility model relates to a pair of shoes and accessories thereof, in particular to a carbon plate, a sole and a pair of shoes. Background Art

[0002] Carbon plate shoes are popular among running enthusiasts for their light weight, elasticity and stability. Application publication number CN115336836A discloses a support plate for running shoe soles, running shoe soles and running shoes, which are made of carbon fiber laid in one piece (i.e., carbon plate), and are provided with a third support section, a first support section and a second support section connected in one piece from front to back, the second support section extends backward from the rear end of the first support section with a preset curvature, the third support section extends forward from the front end of the first support section with a preset curvature, the first support section is suitable for supporting the front part of the metatarsal joint, the front side of the second support section is suitable for supporting the rear part of the metatarsal joint, the first support section extends downward from the front end of the second support section with a preset curvature, the second support section is always higher than the third support section, and the third support section is concave downward along the front-to-back direction. Although the support plate (carbon plate) can achieve lower impact force, greater resilience, less running power loss and higher sports efficiency, however, since the lowest point of the support plate (carbon plate) is located in the third support section, which is relatively forward, it cannot provide forward force for the sole of the foot in the middle and late stages of long-distance running, and the sports efficiency still needs to be improved.

[0003] In view of this, the applicant conducted an in-depth study on the above-mentioned issues, which led to the present case. Utility Model Content

[0004] The utility model aims to provide a carbon plate, a sole and a shoe which are helpful to improve the sports efficiency in the middle and later stages of long-distance running.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A carbon plate comprises a forefoot portion, an arch portion and a heel portion which are integrally connected in sequence, wherein the forefoot portion is an arcuate surface which gradually rises upward from back to front, and the arch portion is an arcuate surface which gradually rises upward from front to back, and the two arcuate surfaces together form a groove, wherein the lowest point of the groove is located at a position where the carbon plate corresponds to a toe bone of a human body, or the lowest point of the groove is located at the rear side of the position where the carbon plate corresponds to a toe bone of a human body.

[0007] As an improvement of the utility model, the carbon plate first gradually bends downward and then gradually bends upward from the inner side of the shoe to the outer side of the shoe at a position corresponding to the toe bone of the human body.

[0008] As an improvement of the utility model, the forefoot portion is provided with a toe-parting groove, the position of the toe-parting groove corresponds to the position between the third toe and the fourth toe of the human body, and the front end of the toe-parting groove has an opening.

[0009] As an improvement of the utility model, the heel portion is provided with a hollow groove, and the rear end of the hollow groove has an opening.

[0010] As an improvement of the present invention, the inner side of the heel portion is integrally connected with an arc-shaped side plate, and the arc-shaped side plate extends to a position corresponding to the arch portion and is integrally connected with the arch portion.

[0011] A shoe sole comprises a midsole and an outsole attached to the lower surface of the midsole, wherein the carbon plate is embedded inside the midsole.

[0012] As an improvement of the present invention, a slope is formed on the upper surface of the midsole, and the slope is gradually inclined upward from front to back. The distance between the front end of the slope and the front end of the midsole is 20% of the length of the midsole, and the distance between the rear end of the slope and the front end of the midsole is 70% of the length of the midsole.

[0013] As an improvement of the present utility model, the height difference of the slope is 5 mm.

[0014] As an improvement of the present invention, the midsole is an EVA midsole, and the outsole is a CPU outsole.

[0015] A shoe comprises an upper connected to the sole.

[0016] By adopting the above scheme, the utility model has the following beneficial effects:

[0017] 1. The utility model forms a groove by setting two arc-shaped surfaces, and the lowest point of the groove is located at the position where the carbon plate corresponds to the human toe bone, or at the rear side of the position where the carbon plate corresponds to the human toe bone, so that the arc of the arch moves upward, and a certain forward force can be provided to the sole of the foot after the midfoot touches the ground, which helps to improve the movement efficiency in the middle and late stages of long-distance running. At the same time, the rearward movement of the lowest point can increase the rolling property of the carbon plate, thereby improving the propulsion performance of the shoe and allowing the user to run faster.

[0018] 2. Because the carbon plate gradually bends downward from the inside of the shoe to the outside of the shoe and then gradually bends upward at the position corresponding to the human toe bone, the carbon plate forms a lateral curvature at the toe bone position, which can better fit the human foot, better prevent eversion, and provide better stability and comfort.

[0019] 3. By opening the toe groove, the lateral strength of the carbon plate can be weakened and the weight can be reduced, thereby improving the flexibility of the shoe during exercise. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] like Figure 1-Figure 4 As shown, this embodiment provides a shoe, including an upper (not shown in the figure) and a sole, wherein the upper is connected to the sole, and the specific connection structure between the two is a conventional structure, which is not the focus of this embodiment and will not be described in detail here.

[0034] For ease of description, in this embodiment, the side of the shoe that contacts the ground during normal use is the lower side, and the corresponding other side is the upper side, the side of the shoe facing the toe is the front side of each component, and the corresponding other side is the back side, the side of the two shoes of a pair of shoes facing each other is the inner side of the shoe, and the corresponding other side is the outer side of the shoe.

[0035] The sole provided in this embodiment can also be sold independently, that is, this embodiment substantially provides a sole. The sole provided in this embodiment includes a midsole 10 and an outsole 20 attached to the lower surface of the midsole 10, wherein a carbon plate 30 is embedded inside the midsole 10, and the midsole 10 can be an integrated midsole or an adhesive midsole. In this embodiment, the midsole 10 includes an upper midsole layer 11 and a lower midsole layer, wherein the lower midsole layer has two relatively independent parts, namely, a front midsole 12 and a rear midsole 13 located at the rear side of the front midsole 12, and the carbon plate 30 is clamped between the upper midsole layer 11 and the lower midsole layer, and is respectively bonded to the upper midsole layer 11 and the lower midsole layer, and the parts of the front midsole 12 and the rear midsole 13 that contact backward are connected by bonding or an integrated connection. This helps to improve the bending performance of the sole. Of course, the outsole 20 is also a split outsole, so that it can be bonded to the front midsole 12 and the rear midsole 13, respectively.

[0036] Preferably, the lower surfaces of the front midsole portion 12 and the rear midsole portion 13 are both formed with inclined surfaces 14 near the ends thereof facing each other, so as to provide support after the sole is bent, thereby improving the stability of the shoe.

[0037] The upper surface of the midsole 10 (i.e., the upper surface of the midsole upper layer 11) is formed with a slope 15, which is arranged to gradually tilt upward from front to back. The distance between the front end of the slope 15 and the front end of the midsole 10 is 20% of the length of the midsole 10, and the distance between the rear end of the slope 15 and the front end of the midsole 10 is 70% of the length of the midsole 10. In addition, the height difference of the slope 15 is 5 mm.

[0038] Preferably, the midsole 10 is an EVA midsole, and the outsole 20 is a CPU outsole, wherein EVA and CPU are both common sole materials, which can be directly purchased from the market and will not be described in detail here.

[0039] The carbon plate 30 provided in this embodiment can also be sold independently or applied to other soles, so this embodiment also substantially provides a carbon plate. The carbon plate 30 provided in this embodiment includes a forefoot portion 31, an arch portion 32 and a heel portion 33 which are connected in sequence as a whole, wherein the forefoot portion 31 is arranged corresponding to the forefoot of a human foot, the arch portion 32 is arranged corresponding to the arch of a human foot, and the heel portion 33 is arranged corresponding to the heel of a human foot. The forefoot portion 31 is an arcuate surface that gradually rises upward from the back to the front, and the arch portion 32 is an arcuate surface that gradually rises upward from the front to the back. The above two arcuate surfaces together form a groove with an opening facing upward, that is, the groove is formed by the arcuate forefoot portion 31 and the arcuate arch portion 32. The lowest point of the groove (which is also the dividing point between the forefoot portion 31 and the arch portion 32) is located at the position corresponding to the toe bone of the human body of the carbon plate 30, or the lowest point of the groove is located on the rear side of the position corresponding to the toe bone of the human body of the carbon plate 30. In this way, the curvature of the arch can be moved upward, and a certain forward force can be provided to the sole of the foot after the midfoot touches the ground, which helps to improve the efficiency of movement in the middle and late stages of long-distance running. At the same time, the rearward movement of the lowest point can increase the rolling property of the carbon plate 30, thereby improving the propulsion performance of the shoe, allowing the user to run faster. It should be noted that the curvature of the forefoot portion 31 and the arch portion 32 is gradual in the length direction of the carbon plate 30, and the curvature of both gradually increases from one end facing each other to the other end. Relatively speaking, the curved surface behind the lowest point of the groove is steeper, which not only provides good support for the midfoot, but also helps to reduce the load on the plantar fascia and reduce the risk of sports injuries.

[0040] Preferably, the carbon plate 30 is gradually bent downward from the inside of the shoe to the outside of the shoe at the position corresponding to the human toe bone and then gradually bent upward, so that the carbon plate 30 forms a lateral curvature at the toe bone position, which can better fit the human foot, better prevent eversion, and provide better stability and comfort. At the same time, at the position corresponding to the human toe bone, the horizontal position of the end of the carbon plate 30 facing the inside of the shoe is lower than the horizontal position of the end facing the outside of the shoe, which helps to further improve the stability of the sole.

[0041] Preferably, the forefoot portion 31 is provided with a toe groove 34, the position of the toe groove 34 corresponds to the position between the third toe and the fourth toe of the human body, and the front end of the toe groove 34 has an opening, which can weaken the lateral strength of the carbon plate and reduce the weight, thereby improving the flexibility of the shoe during exercise; the heel portion 33 is provided with a hollow groove 35, and the rear end of the hollow groove 35 has an opening, which can provide better shock absorption performance.

[0042] In addition, a curved side plate 36 is integrally connected to the inner side of the heel portion 33 , and the curved side plate 36 extends to a position corresponding to the arch portion 32 and is integrally connected to the arch portion 33 to further increase stability.

[0043] 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 equivalent substitutions for the present invention based on the prior art, and all of these belong to the protection scope of the present invention.
