Description

Technical Field

[0001] This invention belongs to the field of footwear technology, and particularly relates to a carbon fiber plate, a sole, and a shoe. Background Technology

[0002] Based on market trends, more and more running enthusiasts are now opting for carbon-plated racing shoes. These shoes can help them achieve better results in races and provide excellent feedback during training.

[0003] Currently, carbon plates in carbon-plated racing shoes typically employ a shovel-shaped structure. A high-efficiency cushioning outsole, disclosed in publication number CN113261745A, includes: an outsole and a midsole; the midsole is located on top of the outsole; the outsole has anti-slip treads on its bottom surface; the midsole is curved and shovel-shaped; the midsole includes a midsole elastic body, a full-length shovel-shaped carbon plate, and a padding elastic layer, stacked sequentially from bottom to top. The rigidity of the full-length shovel-shaped carbon plate reinforces the midsole, providing arch support stability and preventing excessive torsional deformation. While the shovel-shaped structure improves energy return in running shoes, it reduces shock absorption, increasing the risk of lower limb injuries during running. Summary of the Invention

[0004] The purpose of this invention is to provide a carbon fiber plate, a shoe sole, and a shoe to overcome at least one of the aforementioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The carbon plate provided by the present invention includes at least a forefoot section and / or a support section, the forefoot section and / or the support section having a shock-absorbing and rebounding part, and a deformation space between the shock-absorbing and rebounding part and the forefoot section and / or the support section.

[0007] Preferably, the shock-absorbing rebound section is located on the side of the forefoot section and / or the support section away from the human foot.

[0008] Preferably, one end of the shock-absorbing and rebounding part is a fixed end, which is fixedly connected to the forefoot section and / or the support section, and the other end of the shock-absorbing and rebounding part is a free end.

[0009] Preferably, the shock-absorbing rebound portion is arc-shaped, with the center of curvature of the shock-absorbing rebound portion located in the forefoot section being located on the side of the shock-absorbing rebound portion closer to the forefoot section, and the center of curvature of the shock-absorbing rebound portion located in the support section being located on the side of the shock-absorbing rebound portion closer to the support section.

[0010] Preferably, the shock-absorbing rebound section is integrally formed with the forefoot section and / or the support section, and is formed by extending and bending the forefoot section and / or the support section toward the side away from the human foot.

[0011] Preferably, the forefoot section and / or the support section have hollowed-out areas at positions corresponding to the shock-absorbing and rebounding parts.

[0012] Preferably, the carbon plate also includes a midfoot section, one end of which is connected to a forefoot section and the other end to a support section, wherein the shock-absorbing and rebounding part located in the support section is provided at least corresponding to the heel of the human foot.

[0013] Preferably, the carbon plate is a shovel-shaped carbon plate.

[0014] Preferably, the width of the shock-absorbing rebound section is 1 / 7 to 6 / 7 of the maximum width of the forefoot section.

[0015] Preferably, the shock-absorbing and rebounding part located in the forefoot segment includes at least one first shock-absorbing and rebounding body disposed at the metatarsophalangeal joint of the human foot; there is at least one first shock-absorbing and rebounding body, and when there are two or more first shock-absorbing and rebounding bodies, adjacent first shock-absorbing and rebounding bodies are spaced apart along the width direction of the forefoot segment.

[0016] Preferably, one end of the first shock-absorbing rebound body located in the forefoot segment is a fixed end, which is fixedly connected to the forefoot segment, and the connection point is set at the metatarsophalangeal joint of the human foot. The other end of the first shock-absorbing rebound body is a free end, which extends to the side of the ball of the foot away from the midfoot.

[0017] Preferably, the shock-absorbing and rebounding part located in the forefoot section also includes a second shock-absorbing and rebounding body disposed on the side of the plantar ball of the foot away from the midfoot. There is at least one second shock-absorbing and rebounding body. When there are two or more second shock-absorbing and rebounding bodies, adjacent second shock-absorbing and rebounding bodies are spaced apart along the width direction of the forefoot section.

[0018] The present invention also provides a shoe sole comprising the aforementioned carbon plate.

[0019] The present invention also provides a shoe, including the aforementioned sole.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. By incorporating shock-absorbing and rebound components, the carbon plate combines shock absorption and rebound functions, thereby improving energy return in running shoes and reducing lower limb risks.

[0022] 2. The first shock-absorbing rebound body is designed so that when the metatarsophalangeal joint touches the ground, the first shock-absorbing rebound body is compressed to prolong the contact time with the ground and reduce the impact on the ground. When the metatarsophalangeal joint gradually leaves the ground, due to the rigidity of the carbon fiber itself, the compressed first shock-absorbing rebound body undergoes elastic deformation (rebound), thereby achieving the effect of assisting running.

[0023] 3. By setting up the first and second shock-absorbing rebound bodies, a dual shock-absorbing and rebound structure is adopted to further improve the shock absorption and rebound function of the entire shoe in the forefoot.

[0024] 4. The first shock absorber and rebound body is designed as a whole, which can optimize the consistency of force exertion in the forefoot movement and reduce additional energy loss during the movement.

[0025] 5. By using the first and second shock-absorbing rebound bodies set at intervals, the shock absorption and rebound function of the shoe at each toe can be improved.

[0026] 6. The shock-absorbing and rebounding part set in the support section plays a role in shock absorption and rebound in the heel area, which can effectively protect the knee joint. Attached Figure Description

[0041] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

Furthermore, terms such as "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Example 1:

[0044] like Figure 1As shown, the carbon plate provided in this embodiment is a shovel-shaped carbon plate, including a forefoot section 1 (corresponding to the forefoot part of the human foot), a midfoot section 2 (corresponding to the midfoot part of the human foot), and a support section 3 (corresponding to the heel part of the human foot). The left end of the midfoot section 2 is connected to the forefoot section 1, and the right end is connected to the support section 3. The forefoot section 1 has a shock-absorbing and rebounding part 4, which corresponds to the metatarsophalangeal joint of the human foot. In this embodiment, the forefoot section 1, midfoot section 2, support section 3, and shock-absorbing and rebounding part 4 are integrally molded, which facilitates manufacturing and processing. The shock-absorbing and rebounding part 4 is formed by extending and bending the forefoot section 1 away from the human foot, that is, the shock-absorbing and rebounding part 4 is located on the lower side of the forefoot section 1, rather than the upper side of the forefoot section 1. The shock-absorbing and rebounding structure is located on the side away from the human foot, so as not to cause compression to the human foot and affect the wearing comfort. The shock-absorbing and rebounding section 4 is arc-shaped, with its center of curvature located on the side of the section closer to the forefoot segment 1. This arc-shaped design, combined with its placement on the lower side of the forefoot segment 1, makes the shock absorption and rebound process smoother. The arc-shaped design utilizes the excellent rigidity (deformation-resistant ability) of carbon fiber to achieve the shock absorption and rebound function. The right end of the shock-absorbing and rebounding section 4 is a fixed end, fixedly connected to the forefoot segment 1, while the left end is a free end. This arrangement allows the shock-absorbing and rebounding section 4 to have a good deformation range, resulting in excellent shock absorption and rebound effects. In this embodiment, the shock-absorbing and rebounding section 4 is inclined downwards to the left.

[0045] The forefoot section 1 has a hollowed-out area 5 corresponding to the shock-absorbing and rebounding part 4. Specifically, the shock-absorbing and rebounding part 4 is a section formed by cutting three sides of the forefoot section 1 and bending it downwards into an arc shape. The hollowed-out area 5 ensures the effective deformation of the shock-absorbing and rebounding part 4.

[0046] In this embodiment, the shock-absorbing rebound part 4 includes a first shock-absorbing rebound body 41 (with a width of 6 / 7 of the maximum width of the forefoot segment 1) disposed at the metatarsophalangeal joint of the human foot. The specific width is designed within a range according to the actual situation. An integral first shock-absorbing rebound body 41 is disposed at the forefoot of the human foot. Since the load borne by the forefoot (metatarsophalangeal joint) is large, the first shock-absorbing rebound body 41 is placed at the metatarsophalangeal joint (the line connecting the first metatarsal head and the fifth metatarsal head).

[0047] During running, the foot's contact sequence with the ground progresses from the hindfoot / midfoot to the forefoot and toes. When the metatarsophalangeal joint contacts the ground, compression of the first shock-absorbing rebound element 41 prolongs the contact time and reduces ground impact. Figure 2 As shown; subsequently, as the metatarsophalangeal joint gradually leaves the ground, due to the inherent rigidity of the carbon fiber, the compressed first shock-absorbing rebound body 41 undergoes elastic deformation (rebound), as... Figure 3As shown, this achieves the effect of assisting running. The structural design of the integral first shock-absorbing rebound body 41 in this embodiment is based on the principle of integrity in the foot movement process. Although the movements of the first, second, third, fourth, and fifth metatarsophalangeal joints are different, in kinematics, the entire forefoot is usually regarded as a whole to evaluate the forefoot's movement function. Therefore, designing the first shock-absorbing rebound body 41 as an integral unit can optimize the consistency of force exertion in forefoot movement and reduce additional energy loss during the movement process.

[0048] This embodiment also provides a sole, including the carbon plate described above.

[0049] This embodiment also provides a shoe, including the sole described above.

[0050] Example 2:

[0051] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that:

[0052] The shock-absorbing and rebounding section 4 also includes a second shock-absorbing and rebounding body 42 (with a width of 3 / 7 of the maximum width of the forefoot section 1) located on the side of the plantar ball of the foot away from the midfoot (the base of the second, third, and fourth toes). The second shock-absorbing and rebounding body 42 is located to the left of the first shock-absorbing and rebounding body 41. Regardless of whether the running style involves forefoot or heel strike, the foot transitions from the rear to the front. Therefore, this embodiment adopts a dual-layer integrated shock-absorbing and rebounding structure. The first layer of shock-absorbing and rebounding structure (first shock-absorbing and rebounding body 41) is placed at the metatarsophalangeal joint; the second layer of shock-absorbing and rebounding structure (second shock-absorbing and rebounding body 42) is placed at the base of the second, third, and fourth toes. By adopting a dual-layer shock-absorbing and rebounding structure, the overall shock absorption and rebounding function of the shoe in the forefoot (especially the plantar ball) is further improved.

[0053] Example 3:

[0054] like Figure 5 As shown, the difference between this embodiment and Embodiment Two is that:

[0055] There are four first shock-absorbing rebound bodies 41, with adjacent first shock-absorbing rebound bodies 41 spaced apart front to back; there are two second shock-absorbing rebound bodies 42, with adjacent second shock-absorbing rebound bodies 42 spaced apart front to back. The width of each first shock-absorbing rebound body 41 and each second shock-absorbing rebound body 42 is 1 / 7 of the maximum width of the forefoot segment 1. The separate first shock-absorbing rebound bodies 41 and 42 in this embodiment are mainly based on the inconsistent pressure distribution and movement between the toes. Plantar pressure data shows that the first metatarsophalangeal joint and the fifth metatarsophalangeal joint in the bulbus metatarsal region bear the greatest plantar pressure, followed by the second, third, and fourth. Therefore, the first shock-absorbing rebound bodies 41 and the second shock-absorbing rebound bodies 42 are respectively set at these two locations.

[0056] By using the first shock-absorbing rebound body 41 and the second shock-absorbing rebound body 42 spaced apart, the shock absorption and rebound function of the shoe at each toe can be improved.

[0057] Example 4:

[0058] like Figure 6 As shown, the difference between this embodiment and Embodiment Two is that:

[0059] There are two second shock absorber rebound bodies 42, which are arranged at intervals. The combination of integral and separate types is adopted. The integral first shock absorber rebound body 41 is used at the point of maximum pressure to reduce additional energy loss during movement; the separate second shock absorber rebound body 42 is used at the point of less pressure to optimize the shock absorption and rebound function for the second, third and fourth toes.

[0060] Example 5:

[0061] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that:

[0062] The right end of the first shock-absorbing rebound body 41 is a fixed end, which is fixedly connected to the forefoot segment 1, and the connection point is positioned corresponding to the metatarsophalangeal joint of the human foot. The left end of the first shock-absorbing rebound body 41 is a free end, which extends to the side of the metatarsophalangeal part of the human foot away from the midfoot. With this configuration, the shock absorption and rebound effect on the metatarsophalangeal joint and the metatarsophalangeal part can be achieved by using a single first shock-absorbing rebound body 41.

[0063] Example 6:

[0064] like Figure 8 As shown, the difference between this embodiment and Embodiment 3 is that:

[0065] The right end of the first shock-absorbing rebound body 41 is a fixed end, which is fixedly connected to the forefoot segment 1, and the connection point is positioned corresponding to the metatarsophalangeal joint of the human foot. The left end of the first shock-absorbing rebound body 41 is a free end, and the free ends of the two first shock-absorbing rebound bodies 41 located on the front and rear sides extend to the side of the metatarsophalangeal part of the human foot away from the midfoot. This arrangement ensures shock absorption and rebound for the metatarsophalangeal joint while further improving the shock absorption and rebound effect for the metatarsophalangeal part.

[0066] Example 7:

[0067] like Figure 9-10 As shown, the difference between this embodiment and Embodiment 1 is that:

[0068] Both the forefoot section 1 and / or the support section 3 have shock-absorbing and rebounding parts 4, with the shock-absorbing and rebounding parts 4 located in the support section 3 corresponding at least to the heel of the human foot. Through the design of the shock-absorbing and rebounding parts 4 located in the support section 3, shock absorption and rebound are achieved in the heel area, effectively protecting the knee joint.

[0069] Example 8:

[0070] like Figure 11-13 As shown, the difference between this embodiment and Embodiment 1 is that:

[0071] In this embodiment, the shock-absorbing and rebounding part 4 is inclined to the lower right.
