Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a shaped plate, a sole, and a shoe. Background Technology

[0002] One of the purposes of athletic footwear is to improve athletic performance. With the development of midsole materials and technologies, supercritical technology has made midsoles increasingly less dense and more elastic, leading to the increasing prevalence of athletic shoes that incorporate carbon fiber plates. The carbon fiber plate primarily balances the midsole materials, improves stability, and enhances athletic performance by increasing the lever arm of the ankle joint during push-off through its rigidity.

[0003] Running postures are categorized into three types based on their strike pattern: forefoot strike, midfoot strike, and heel strike. Different running postures result in different force distributions. Current athletic shoe designs primarily optimize carbon plate shapes for a single strike pattern. However, during a marathon, runners' postures are constantly adjusting and changing, especially in the latter half of the race (after 30km), as their running form naturally adjusts due to fatigue. Therefore, carbon plate athletic shoes designed for a single strike pattern cannot fully meet the actual needs of runners in a marathon. Utility Model Content

[0004] The purpose of this invention is to provide a non-circular plate, sole, and shoe that can adapt to different running postures.

[0005] To achieve the above objectives, the technical solution proposed by this utility model is as follows:

[0006] An irregularly shaped plate includes a one-piece molded forefoot, midfoot, and heel section. The forefoot section includes a forefoot support portion and two forefoot cushioning and rebound portions located on the inner and outer sides of the forefoot support portion, respectively. Both the forefoot support portion and the two forefoot cushioning and rebound portions extend forward from the front end of the midfoot. The forefoot support portion and the forefoot cushioning and rebound portions are separate from each other, and the forefoot cushioning and rebound portions are located above or below the forefoot support portion in the plate thickness direction. The heel section includes a heel cushioning portion extending rearward from the rear end of the midfoot, and the heel cushioning portion is located below the midfoot in the plate thickness direction.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] In the following description, the terms indicating direction such as foot length, foot width, front, back, inner side, and outer side are observed from the wearer's perspective. For example, front refers to the direction of the toes, back refers to the direction of the heel, inner side refers to the inner side of the foot (the side of the first toe) in the direction of foot width, and outer side refers to the outer side of the foot (the side of the fifth toe) in the direction of foot width.

[0032] Example 1

[0033] Reference Figures 1-3 A non-standard plate includes an integrally formed forefoot portion 1, midfoot portion 2, and heel portion 3. The forefoot portion 1 includes a forefoot support portion 11 and two forefoot cushioning and rebound portions 12 located on the inner and outer sides of the forefoot support portion 11, respectively. Both the forefoot support portion 11 and the two forefoot cushioning and rebound portions 12 extend forward from the front end of the midfoot portion 2. The forefoot support portion 11 and the forefoot cushioning and rebound portions 12 are separate from each other, with the forefoot cushioning and rebound portions 12 positioned above the forefoot support portion 11 in the plate thickness direction. The heel portion 3 includes a heel cushioning portion 31 extending rearward from the rear end of the midfoot portion 2, with the heel cushioning portion 31 positioned below the midfoot portion 2 in the plate thickness direction.

[0034] The forefoot portion 1 typically corresponds to the area of ​​the metatarsophalangeal joint and the phalangeal joint. The forefoot portion 1, midfoot portion 2, and heel portion 3 are not intended to divide the footwear components into precise areas, but rather to indicate the approximate relative areas of the footwear components.

[0035] In this embodiment, the forefoot cushioning and rebound section 12 of the irregularly shaped plate provides both cushioning upon landing and rebound upon push-off. Upon forefoot landing, the forefoot cushioning and rebound section 12 deforms to absorb the impact force. Upon push-off (regardless of running posture), the deformation of the forefoot cushioning and rebound section 12 recovers, thus providing a propulsive effect. The heel cushioning section 31 of the irregularly shaped plate provides cushioning for heel-strike running postures. Upon heel strike, the heel cushioning section 31 deforms, providing cushioning. For other running postures, the irregularly shaped plate in this embodiment provides a rebound effect.

[0036] The forefoot support section 11 and the midfoot section 2 provide stable support for the forefoot and midfoot, reducing the risk of sports injuries and improving wearing comfort.

[0037] The special structure of the forefoot portion 1 and heel portion 3 of the irregular plate in this embodiment can adapt to different running postures and can dynamically respond to the dynamic switching of different running postures during running, breaking through the limitations of traditional carbon plates in single-condition optimization, thereby better improving athletic performance and reducing the occurrence of sports injuries.

[0038] In this embodiment, both the forefoot cushioning and rebound portion 12 and the forefoot support portion 11 are arc-shaped, concave downwards along the length of the foot. The arc-shaped design helps to improve the propulsion and stability of the irregularly shaped plate, facilitates energy storage and release, and improves the rebound performance of the irregularly shaped plate.

[0039] Reference Figure 3 The dashed elliptical frame, from right to left, represents the first to fifth metatarsophalangeal joints. Each metatarsophalangeal joint is formed by the metatarsal head and the base of the proximal phalanx. These joints are the core fulcrum for the foot's push-off from the ground, responsible for flexion and extension movements during the push-off phase of running to propel the body forward. In this embodiment, the lowest point of the forefoot cushioning rebound section 12 corresponds to the metatarsophalangeal joint. Aligning the lowest point of the arc-shaped forefoot cushioning rebound section 12 with the metatarsophalangeal joint matches the natural movement trajectory of the joint, concentrating the push-off force to the metatarsophalangeal joint and thus improving push-off efficiency.

[0040] The transverse arch of the foot, located between the first to fifth metatarsal bones, is an important supporting structure of the foot, exhibiting an upwardly convex arc shape. Under non-weight-bearing conditions, the first and fifth metatarsal heads are in contact with the ground through soft tissue, while the second to fourth metatarsal heads are off the ground. Therefore, in this embodiment, the forefoot cushioning and rebound portion 12 located on the inner side of the forefoot support portion 11 at least covers the first phalanx and the first metatarsophalangeal joint, and the forefoot cushioning and rebound portion 12 located on the outer side of the forefoot support portion 11 at least covers the fifth phalanx and the fifth metatarsophalangeal joint, to ensure good push-off force.

[0041] In this embodiment, the irregularly shaped plate is a carbon fiber plate, preferably a T700 carbon fiber plate, a T800 carbon fiber plate, or a T900 carbon fiber plate. T700-T900 carbon fiber plates have excellent mechanical properties, stronger overall rigidity, lighter material, and can maintain stable performance under high-frequency stress cycling.

[0042] The thickness of the irregularly shaped plate in this embodiment is 0.6 to 1.5 mm.

[0043] To balance lightweight and rigidity, the thickness of the plate in the midfoot portion 2 is preferably 1.2 mm, the thickness of the plate in the forefoot portion 1 is increased to 1.5 mm, and the thickness of the plate in the heel portion 3 is reduced to 1 mm. Increasing the thickness of the forefoot portion 1 can increase support and rebound, and prevent the irregular plate from breaking at the metatarsophalangeal joint.

[0044] Example 2

[0045] Reference Figures 4-6 The difference between this embodiment and the first embodiment is that the heel part 3 in this embodiment also includes two heel support parts 32 located on the inner and outer sides of the heel cushioning part 31 respectively. Both heel support parts 32 extend backward from the rear end of the midfoot part 2 and are separated from the heel cushioning part 31. The heel cushioning part 31 is located below the heel support part 32 in the plate thickness direction.

[0046] The heel support 32 provides stable support for the heel, preventing excessive inward or outward rotation of the calcaneus in the foot width direction, which could lead to ankle sprains, and thus provides protection.

[0047] Example 3

[0048] Reference Figures 7-9 The difference between this embodiment and embodiment two is that the forefoot cushioning and rebound part 12 in this embodiment is located below the forefoot support part 11 in the plate thickness direction, and can also play a buffering role when the forefoot hits the ground and play a rebound role when pushing off.

[0049] Example 4

[0050] Reference Figure 10 The difference between this embodiment and embodiment two is that the area of ​​the heel cushioning rebound part corresponding to the heel bone of the foot in this embodiment is circular to improve the cushioning effect and rigidity.

[0051] Example 5

[0052] This embodiment provides a shoe sole, including a midsole and a shaped plate disposed within the midsole. The shaped plate in this embodiment is any one of the shaped plates in Embodiments 1 to 4.

[0053] This embodiment also provides a shoe including the sole.

[0054] The sole and other parts of the shoe not covered are the same as or can be implemented using existing technology, and will not be described in detail here.

[0055] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
