Description

Technical Field

[0001] This utility model relates to the field of shoe sole structure technology, and more specifically to a spring-loaded support piece and a shoe sole using the spring-loaded support piece. Background Technology

[0002] Current athletic shoes, running shoes, and casual shoes mostly use a single midsole cushioning material, such as EVA or PU foam, to provide a certain level of cushioning. However, these soles have some problems, such as uneven cushioning distribution. The overall cushioning performance of the sole cannot be zoned to address the different pressure points of the forefoot, heel, and arch, easily leading to concentrated localized stress and increased joint and foot fatigue. Another issue is insufficient arch support; traditional soles cannot fully match the curvature of the human foot arch, causing the arch to collapse during exercise, potentially leading to foot discomfort or injury with prolonged use. Some soles also have limited rebound capacity; the rebound of the single midsole material cannot simultaneously meet the elasticity needs of different areas, resulting in insufficient energy return during exercise, affecting foot comfort and athletic efficiency. Therefore, there is an urgent need for a sole structure that can achieve zoned cushioning, arch support, and rebound assistance to improve the comfort and performance of athletic shoes. Utility Model Content

[0003] In view of this, the present invention provides a spring-assisted piece and a shoe sole using the spring-assisted piece.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An elastic support plate includes: a forefoot portion, the forefoot portion comprising an upper forefoot portion and a lower forefoot portion, the forefoot portion being a shell-shaped portion opening forward, and the upper forefoot portion and the lower forefoot portion each having a plurality of strip-shaped portions radiating outward along the width direction of the forefoot portion; a heel portion, the heel portion comprising an upper heel portion and a lower heel portion, the heel portion being a shell-shaped portion opening backward; and an arch support portion, the arch support portion having an arc-shaped structure and connecting the forefoot portion and the heel portion; wherein, the strip-shaped portions of the forefoot portion are capable of elastically cushioning deformation under different landing forces on the forefoot.

[0006] In a preferred embodiment, the forefoot, heel, and arch connection are integrally molded from thermoplastic polyurethane elastomer (TPU), nylon, or carbon fiber composite material.

[0007] In a preferred embodiment, the upper and lower layers of the heel have a fan-shaped expansion structure, and gradually widen from the connection point with the arch of the foot.

[0008] In a preferred embodiment, the upper surface of the arch connector is configured as a biomimetic curved surface to support the human arch.

[0009] In a preferred embodiment, the forefoot has at least three strip-shaped portions, which are radially distributed along the width of the forefoot.

[0010] In a preferred embodiment, the upper and lower forefoot layers, and the upper and lower heel layers are connected by an elastic material.

[0011] In a preferred embodiment, the length of the strip gradually decreases or increases to create a graded buffering effect.

[0012] In a preferred embodiment, the thicknesses of the upper forefoot layer, lower forefoot layer, upper heel layer, and lower heel layer are set to be different to create a layered cushioning effect.

[0013] In a preferred embodiment, a shoe sole is provided with the aforementioned elastic support piece.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0015] The strip-shaped section in the forefoot can elastically deform according to the landing conditions of different areas of the forefoot, while the fan-shaped shell structure in the heel effectively absorbs heel impact, thus achieving localized pressure dispersion and reducing impact concentration. The biomimetic curved surface of the arch support matches the structure of the human foot arch, providing support and transition for the arch during exercise, preventing arch collapse or fatigue. The overall elastic design of the materials used in the forefoot, heel, and arch support enhances the overall resilience of the sole, providing energy feedback for exercise and improving foot comfort. TPU, nylon, or carbon fiber composite materials can be selected, balancing elasticity, strength, and durability, while also being suitable for industrial production and mass production. This spring plate can be embedded in various shoe types such as athletic shoes, running shoes, and casual shoes, effectively improving comfort and reducing fatigue during long-term walking or exercise. In summary, this utility model, through innovative structural design and material selection, achieves a comprehensive technical effect of "zoned cushioning + arch support + rebound assistance," solving the technical defects of existing shoe soles and possessing significant practical value.

[0024] Example 1

[0025] like Figures 1 to 3As shown, this utility model provides a spring-loaded support piece, which is generally elongated and adapted to be installed inside the sole 400. The spring-loaded support piece mainly includes a forefoot portion 100, a heel portion 200, and an arch support portion 300 connecting the two. The forefoot portion 100 is located in the front end area of ​​the spring-loaded support piece, positioned below the forefoot of the human foot. The forefoot portion 100 includes an upper forefoot layer 111 and a lower forefoot layer 112, spaced apart to form a forward-opening shell-like structure. Multiple strip-shaped portions 113 are evenly distributed on the upper forefoot layer 111 and the lower forefoot layer 112, radiating outwards along the width of the forefoot. Preferably, the number of strip-shaped portions 113 is 3 to 8, each strip-shaped portion 113 gradually extending from the inside to the outside of the forefoot. When the foot is subjected to force at different points of contact, the strip 113 can undergo independent elastic deformation, thereby providing local cushioning and support and avoiding impact concentration caused by force in a single direction.

[0026] Furthermore, the heel portion 200 is located at the rear end of the spring-loaded plate, positioned below the heel. The heel portion 200 also includes an upper heel layer 211 and a lower heel layer 212, spaced apart to form a rearward-opening shell-like structure. In a preferred embodiment, the upper heel layer 211 and the lower heel layer 212 are fan-shaped, gradually widening rearward from their connection with the arch connector 300, thereby increasing the contact area and enhancing the cushioning capacity of the heel area. When the heel strikes the ground, the heel portion 200 undergoes elastic deformation, effectively absorbing impact and reducing joint pressure. The arch connector 300 is located in the middle of the spring-loaded plate, connecting the forefoot portion 100 and the heel portion 200. The arch connector 300 has an overall arc-shaped structure, with its upper surface designed as a biomimetic curved surface to match the natural curvature of the human foot arch. During exercise, the arch support 300 plays a supporting and transitional role, ensuring the coordination of force on the forefoot and heel, and enhancing the overall resilience of the sole 400.

[0027] Furthermore, in a preferred embodiment, the forefoot 100, heel 200, and arch support 300 are integrally molded from thermoplastic polyurethane elastomer (TPU), which offers both good elasticity and abrasion resistance, and is easy to industrialize. In another embodiment, nylon or carbon fiber composite materials can also be used, manufactured through injection molding or compression molding processes to enhance strength and durability.

[0028] Furthermore, during use, the strip-shaped portion 113 of the forefoot 100 can deform according to the landing conditions of different areas of the forefoot, thereby dispersing pressure and avoiding concentrated local impact; the shell-shaped fan-shaped structure of the heel 200 can effectively absorb the impact force when the heel strikes; the biomimetic curved surface of the arch support 300 can provide arch support and prevent arch collapse or fatigue. Overall, this spring plate can achieve a comprehensive effect of "zoned cushioning + arch support + rebound assistance", improving the comfort and athletic performance of the sole 400.

[0029] Furthermore, in other embodiments, the forefoot portion 100, the heel portion 200, and the arch support portion 300 can be integrally molded from thermoplastic polyurethane elastomer (TPU), nylon, or carbon fiber composite material, thereby ensuring both elasticity and strength. In other embodiments, the upper layer 211 and the lower layer 212 of the heel portion have a fan-shaped expansion structure, and gradually widen rearward from the connection point with the arch support portion 300 to increase the cushioning area when the heel strikes the ground.

[0030] In other embodiments, the upper surface of the arch connector 300 is constructed in a biomimetic curved shape to match the physiological structure of the human foot arch, thereby improving arch support and comfort.

[0031] In other embodiments, the forefoot portion 100 has at least three strip-shaped portions 113, which are radially distributed along the width of the forefoot portion to adapt to different force conditions in different directions of the forefoot.

[0032] In other embodiments, the upper forefoot layer 111 and the lower forefoot layer 112, and the upper heel layer 211 and the lower heel layer 212 are connected by an elastic material, thereby forming a secondary buffer between the layers.

[0033] In other embodiments, the length of the strip 113 gradually decreases or increases to create a graded buffering effect, meeting the force requirements of different areas.

[0034] In other embodiments, the thicknesses of the upper forefoot layer 111, the lower forefoot layer 112, the upper heel layer 211, and the lower heel layer 212 are set to be different to form a layered cushioning effect and further improve cushioning performance.

[0035] Furthermore, such as Figure 3As shown, this utility model also provides a shoe sole, in which the sole 400 is provided with the elastic support piece described in any of the above embodiments. When this shoe sole is used in sports shoes, running shoes, or casual shoes, it can effectively improve the overall elastic feedback and foot comfort, and reduce fatigue during long-term walking or exercise. In the application of this utility model, the elastic support piece is arranged longitudinally along the sole, with the forefoot portion located below the forefoot of the sole, the heel portion located below the heel of the sole, and the arch support portion corresponding to the arch area of ​​the sole. The elastic support piece can be fixed by embedding into the sole mold or by adhesive bonding, or it can be integrally injection molded with the midsole material, thereby ensuring that the elastic support piece and the sole work together during exercise to achieve a comprehensive effect of zoned cushioning, arch support, and rebound assistance.
