Description

Open elastic structure Technical Field

[0001] This invention relates to an elastic structure, specifically an open elastic structure. Background Technology

[0002] Traditional applications of elastic materials, such as rubber, elastic plastics, and foams, provide basic elasticity and cushioning. However, these materials typically rely on thickness to provide elasticity and support. This fixed thickness makes it impossible to controllably adjust the elasticity and support, resulting in insufficient performance to meet modern consumers' demands for high performance and versatility.

[0003] In view of this, developing an open, resilient structure is the goal of development in related fields.

[0004] Summary of the Invention

[0005] To address the growing need for highly flexible and supportive products in modern life and sports activities, providing users with better comfort, protection, and performance, this invention provides an open-structure elastic structure comprising:

[0006] A single sheet, which is a thin sheet; and

[0007] An elastomer structure is a multilayer structure comprising a plurality of elastomers stacked together, wherein each elastomer has a curvature and corresponds to at least one portion of a sheet, and a fixing portion fixing the elastomers together and at least one portion of the sheet, wherein the end of each elastomer has a length direction space, and wherein at least a portion of each elastomer has an extension space.

[0008] The area of ​​the elastomer decreases from large to small along the stacking direction.

[0009] Furthermore, the concave surfaces are all stacked facing the sheet body.

[0010] Furthermore, a portion of the concave surfaces of each elastomer are stacked facing the sheet body, while another portion of the concave surfaces of each elastomer are stacked facing away from the sheet body, wherein the central curved tops of two elastomers abut against each other.

[0011] The elastomer is either yarn-like or mesh-like.

[0012] The elastomer comprises carbon fiber, polyester fiber, glass fiber, aramid fiber, or ceramic fiber.

[0013] The bending methods for each elastomer include bending after local heating, manual bending, or mechanical bending.

[0014] The fixing method of the fixing part includes mechanical fixing, sewing or fastening system.

[0015] Furthermore, the piece is an insole, comprising a midfoot portion, a forefoot portion, and a heel portion. The midfoot portion is located in the middle of the piece, the front end of the midfoot portion is the forefoot portion, and the rear end of the midfoot portion is the heel portion.

[0016] Furthermore, the elastic structure is disposed in the middle foot.

[0017] Furthermore, the elastomer structure is respectively disposed on the forefoot portion and the heel portion.

[0018] Based on the above, the effects of this invention can be summarized as follows:

[0019] 1. The elastomer structure provides local support and elasticity to the sheet, enabling the sheet to effectively disperse stress and provide resilience, thereby reducing damage caused by deformation or impact and improving the durability and stability of the sheet. The number of layers and materials of the multi-layer structure can be adjusted according to the user's needs to achieve the best support effect and comfort.

[0020] 2. Multiple elastomers provide different degrees of elasticity and support. Each elastomer has a different size and corresponds to at least one part of the sheet. When the elastomers are stacked, the area decreases from large to small, providing the sheet with precise distribution of support and elasticity. At the same time, the elastic area and the rigid area are distributed in different parts of the sheet, enhancing the applicability of the sheet.

[0021] 3. The concave surface extends spatially along the length of the sheet as the stress increases, effectively dispersing the stress at the ends of each elastomer, thereby reducing local damage caused by stress concentration and improving overall durability. When the stress is released, each elastomer can also recover its original shape through its own resilience, further improving the service life of the elastomer structure.

[0022] 4. The fixing part maintains the stability between each of the elastic bodies and the sheet body. The fixing part 22 is provided at the thickest part of the plurality of elastic bodies to ensure that each elastic body will not rotate or shift when subjected to the stress, thereby maintaining the stability and functionality of the structure.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings:

[0040] The present invention provides an open elastic structure comprising a sheet 10 and an elastic structure 20.

[0041] The sheet 10 is a thin sheet, and its shape is not limited. It can be designed according to the shape of the object to which the sheet 10 is applied, such as a shoe insole or a protective gear.

[0042] Please refer to Figures 1 and 2. In a preferred embodiment of the present invention, the plate 10 is an insole, which includes a midfoot portion 11, a forefoot portion 12 and a heel portion 13. The midfoot portion 11 is located in the middle of the plate 10. The front end of the midfoot portion 11 is the forefoot portion 12, which corresponds to the area below the toes. The rear end of the midfoot portion 11 is the heel portion 13, which corresponds to the area below the heel.

[0043] The elastomer structure 20 includes multiple elastomers 21, a fixing part 22, an elastic region 22, and a rigid region 23.

[0044] The elastomer structure 20 is a multi-layered structure composed of multiple stacked elastomers 21. When the elastomer structure 20 is disposed at at least one part of the sheet 10, it can provide local support and elasticity to the sheet 10. Furthermore, when the elastomer structure 20 is subjected to stress from the sheet 10, its multi-layered design effectively disperses the stress and provides resilience, thereby reducing damage caused by deformation or impact and enhancing the overall durability and stability of the sheet 10. In addition, the number of layers and the material of the multi-layered structure can be adjusted as needed to adapt to different applications or performance requirements, achieving optimal support and comfort.

[0045] Each of the multiple elastomers 21 includes a concave surface 211. Each elastomer 21 is a yarn-like or mesh-like structure, wherein the shape of each elastomer 21 is not limited, and the shape of each elastomer 21 corresponds to at least a portion of the sheet 10. The size of each elastomer 21 is different, and the size of each elastomer 21 gradually decreases relative to a portion of the sheet 10. In this way, when the elastomers 21 are stacked, the area of ​​each elastomer 21 decreases from large to small in a stacking direction.

[0046] Each of the elastomers 21 is a fiber composite material with both elasticity and rigidity, including carbon fiber, polyester fiber, glass fiber, aramid fiber or ceramic fiber.

[0047] Furthermore, each of the elastic bodies 21 is bent so that each of the elastic bodies 21 has a curvature. The sheet body 10 can adjust the curvature as needed. When the elastic body 21 is subjected to stress, the curvature can evenly distribute the stress, further improving the support effect and resilience of the sheet body 10.

[0048] The bending methods of the elastomer 21 include bending after local heating, manual bending, or mechanical bending.

[0049] Please refer to Figures 1 and 3. The concave surface 211 is the surface of the elastic body 21 that is bent inward. In one embodiment, the concave surfaces 211 of each elastic body 21 are stacked facing the sheet body 10. In another embodiment, a portion of the concave surfaces 211 of each elastic body 21 are stacked facing the sheet body 10, and another portion of the concave surfaces 211 of each elastic body 21 are stacked facing away from the sheet body 10. In this case, the central curved tops of two elastic bodies 21 abut against each other.

[0050] Furthermore, when the sheet 10 receives the stress, the angle of the concave surface 211 decreases, and the concave surface 211 extends spatially along a length direction of the sheet 10, causing the concave surface 211 to deform. This allows the elastomer structure 20 to better distribute the stress. Furthermore, as the stress increases, the spatial extension of the concave surface 211 along a length direction also increases, reducing local damage caused by stress concentration in the sheet 10 and further improving the overall durability and stability of the sheet 10. When the stress is released or reduced, the concave surface 211 returns to its original shape through its own resilience, further extending the service life of the elastomer structure 20.

[0051] The fixing part 22 is not limited in its fixing structure. The fixing part 24 is disposed at the thickest part of the plurality of elastic bodies 21, wherein the fixing part 24 is fixed to each elastic body 21 and the sheet body 10. Furthermore, when the sheet body 10 is subjected to stress, the elastic bodies 21 still maintain the extension of the longitudinal space, and the elastic bodies 21 will not rotate or shift, thereby maintaining the overall stability and functionality of the elastic body structure 20.

[0052] The fixing method of the fixing part 24 is not limited; it can be mechanical fixing, sewing, or a fastener system.

[0053] The elastic region 23 refers to the area around a ring of the multiple elastic bodies 21, wherein the area around the ring is a tapered layer, such that the ends of each elastic body 21 are tapered by the sheet 10. Furthermore, the elasticity of the elastic region 23 gradually decreases from the ends of each elastic body 21, forming a gradual elastic change. This allows the elastic region 23 to uniformly distribute the stress along the length direction of each elastic body 21 when the sheet 10 comes into contact with the stress, and effectively mitigate the stress.

[0054] Furthermore, when the sheet 10 is subjected to a large stress, each of the elastic bodies 21 is parallel to the sheet 10, and the elastic region 23 will be reduced. The end of the elastic body 21 still retains the tapered layer, and the end of the elastic body 21 still has the local elastic region 23, thereby maintaining the overall stability and comfort of the sheet 10, preventing excessive wear or damage to the sheet 10 in some areas, and extending the service life of the sheet 10.

[0055] The rigid region 24 refers to the overlapping area of ​​the multiple elastic bodies 21. The rigid region 24 is also the thickest part of the multiple elastic bodies 21. The contact area of ​​each elastic body 21 is large, which increases the friction between the elastic bodies 21 and further provides support for the sheet 10.

[0056] When the sheet 10 is subjected to a large stress, each of the elastic bodies 21 is parallel to the sheet 10. At this time, the rigid area 24 will become larger, and the friction between the elastic bodies 21 will also increase. This allows the sheet 10 to provide a more stable and uniform support effect when subjected to the stress, while making the overall structure of the sheet 10 more robust and further improving the durability of the sheet 10.

[0057] Further, referring to Figures 1 and 2, in the first embodiment of the present invention, the elastomer structure 20 may be disposed on the midfoot portion 11 of the sheet body 10, and the elastomer 21 is stacked below the midfoot portion 11, wherein the area of ​​the elastomer 21 decreases from top to bottom, and the concave surfaces 211 all face the sheet body 10, such that the forefoot portion 12 and the heel portion 13 have the elastic area 23, and the midfoot portion 11 has the rigid area 24.

[0058] The elastomeric structure 20 provides basic support and cushioning for the sheet 10, effectively reducing energy loss and foot fatigue during movement transitions in walking or running, and enhancing comfort and cushioning. The elastomeric structure 20 is particularly suitable for applications requiring low performance and comfort, such as lightweight running shoes or casual shoes.

[0059] Further, referring to Figure 3, in the second embodiment of the present invention, the elastomer structure 20 can be disposed on the midfoot portion 11 of the sheet 10, and the elastomer 21 is stacked below the midfoot portion 11. The area of ​​the elastomer 21 decreases from top to bottom. A portion of the concave surface 211 faces the sheet 10 first, and another portion of the concave surface 211 faces away from the sheet 10. In this way, the forefoot portion 12 and the heel portion 13 have the elastic area 23, and the midfoot portion 11 has the rigid area 24. The difference from the first embodiment is that the elastic area 23 greatly increases the elastic space, so that the forefoot portion 12 and the heel portion 13 are covered with greater elasticity, and the rigid area 24 greatly increases the support.

[0060] The enhancement of the elastic zone 23 not only improves the cushioning effect of the forefoot 12 and heel 13, but also significantly improves the flexibility and adaptability of the plate 10. It can absorb stress and provide better cushioning. At the same time, the enhancement of the rigid zone 24 allows the plate 10 to stably support sudden changes of direction or jumps and maintain the balance of the midfoot 11. The design of the elastomer structure 20 is particularly suitable for applications that require high flexibility and high support, such as racing shoes, basketball shoes or hiking shoes.

[0061] Further, referring to Figure 4, in the third embodiment of the present invention, the elastomer structure 20 is respectively disposed on the forefoot portion 12 and the heel portion 13 of the plate 10, and the elastomer 21 is stacked below the forefoot portion 12 and the heel portion 13, wherein the area of ​​the elastomer 21 decreases from top to bottom, and the concave surfaces 211 all face the plate 10, so that the forefoot portion 12 and the heel portion 13 have the rigid area 24, while the midfoot portion 11 has the elastic area 23. When the plate 10 is subjected to stress, the forefoot portion 12 and the heel portion 13 can provide good support and stability, while the midfoot portion 11 has better flexibility and comfort. In addition, the tapered layers of the multiple elastomers 21 effectively absorb the stress and improve overall comfort, so that good stability and comfort can be maintained under different ground conditions. The design of the elastomer structure 20 is particularly suitable for high flexibility or fast foot movement, such as dance shoes or gymnastics shoes.

[0062] Based on the above, the effects of this invention can be summarized as follows:

[0063] 1. The elastomer structure 20 provides local support and elasticity to the sheet 10, enabling the sheet 10 to effectively disperse stress and provide resilience, thereby reducing damage caused by deformation or impact and improving the durability and stability of the sheet 10. The elastomer structure 20 can adjust the number of layers and materials of the multi-layer structure according to the user's needs to achieve the best support effect and comfort.

[0064] 2. Multiple elastomers 21 provide different degrees of elasticity and support. Each elastomer 21 has a different size and corresponds to at least one part of the sheet 10. The area of ​​each elastomer 21 decreases from large to small in the stacking direction, providing the sheet 10 with precise distribution of support and elasticity. At the same time, the elastic area 23 and the rigid area 24 are distributed in different parts of the sheet 10, enhancing the applicability of the sheet 10.

[0065] 3. The concave surface 211 will extend spatially along the length direction of the sheet 10 as the stress increases, and effectively disperse the stress at the ends of each elastic body 21, thereby reducing local damage caused by stress concentration and improving overall durability. When the stress is released, each elastic body 21 can also restore its original shape through its own rebound force, further improving the service life of the elastic body structure 20.

[0066] 4. The fixing part 22 maintains the stability between each of the elastic bodies 21 and the sheet body 10. The fixing part 22 is provided at the thickest part of the plurality of elastic bodies 21 to ensure that each elastic body 21 will not rotate or shift when subjected to the stress, thereby maintaining the stability and functionality of the structure.

[0067] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
