Description

Technical Field

[0001] This utility model relates to the field of athletic shoe design technology, and more specifically, to a lateral grip structure for the outsole of an athletic shoe designed specifically for women. Furthermore, it also relates to an athletic shoe incorporating the aforementioned lateral grip structure for the outsole designed specifically for women. Background Technology

[0002] In existing technology, traditional women's sports shoes 01, such as Figure 1 As shown, most of their soles use a longitudinal groove design. Moreover, the traditional single longitudinal groove will result in the athletic shoe having only forward anti-slip grip F1, resulting in insufficient lateral grip F2. This makes it easy for female users to lose their balance and fall when performing dance spins. In other words, the existing single longitudinal groove will cause users to lack stability during complex directional movements.

[0003] In conclusion, how to provide a sports shoe that can improve lateral grip and avoid the loss of stability during complex directional changes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a lateral grip structure for the outsole of sports shoes designed specifically for women, which can help improve the lateral grip of sports shoes and prevent users from losing stability during complex directional movements.

[0005] Another objective of this invention is to provide a sports shoe that includes the aforementioned lateral grip structure on the outsole of a sports shoe specifically designed for women.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lateral traction structure for the outsole of an athletic shoe designed specifically for women includes:

[0008] The forefoot area has multiple spaced-apart lateral ripples that extend along the length of the shoe. The ratio of the total area of ​​the lateral ripples to the area of ​​the forefoot area is X, where X is greater than or equal to 50%.

[0009] The heel region is provided with a particle matrix, wherein the ratio of the total area of ​​all the particles in the particle matrix to the area of ​​the heel region is Y, where Y is less than X;

[0010] The transition zone is located between the forefoot area and the heel area. The transition zone includes a plurality of longitudinal ripples arranged at intervals with gradually decreasing ripple size. The longitudinal ripples extend along the width direction of the athletic shoe.

[0011] In one embodiment, the ratio of the ripple depth of the transverse corrugations to the diameter of the particles ranges from 1:1.8 to 1:2.2.

[0012] In one embodiment, the width of the transverse corrugations ranges from 3mm to 5mm, the spacing between two adjacent transverse corrugations ranges from 2mm to 4mm, the diameter of the particles ranges from 4mm to 6mm, and the height of the particles ranges from 1.2mm to 1.8mm.

[0013] In one embodiment, the forefoot area, the transition area, and the heel area are an integral structural component.

[0014] In one embodiment, the integral structure includes a rubber component.

[0015] In one embodiment, the hardness range of the integral structure is 50A-60A.

[0016] In one embodiment, the hardness difference between the forefoot hardness and the heel hardness is greater than or equal to 5A.

[0017] In one embodiment, the particles comprise circular particles or a hexagonal honeycomb structure.

[0018] In one embodiment, the transverse corrugations include wavy corrugations or sawtooth corrugations.

[0019] An athletic shoe comprising the lateral grip structure of an outsole designed specifically for women as described in any of the preceding claims.

[0020] When using the lateral grip structure of the outsole of the sports shoe designed specifically for women provided by this utility model, the forefoot area has multiple spaced lateral ripples, and the ratio of the total area of ​​each lateral ripple to the area of ​​the forefoot area is X, where X is greater than or equal to 50%. The heel area has a particle matrix, and the ratio of the total area of ​​each particle to the area of ​​the heel area is Y, where Y is less than X. Moreover, the transition zone includes multiple longitudinal ripples arranged in sequence with gradually decreasing ripple size, that is, the transition zone is a structural design where ripples gradually transition to particles. Since the lateral ripples in the forefoot area occupy 50% or more of the forefoot area, the unevenness of the lateral ripples generates greater friction, resulting in greater grip for the sports shoe. Furthermore, the outsole of the sports shoe of this application is a composite pattern including lateral ripples, a particle matrix, and longitudinal ripples with gradually decreasing ripple amplitude. The direction of the composite pattern can cover 360°. The ripple deformation in the forefoot area stores energy, and the particle interlocking in the heel area releases energy, effectively increasing the friction contact surface of the outsole and improving the lateral grip and energy return rate of the outsole.

[0021] In summary, the lateral grip structure of the outsole of the sports shoe provided by this utility model, which is designed specifically for women, can help improve the lateral grip of the sports shoe and prevent users from losing stability during complex directional movements.

[0022] In addition, this utility model also provides a sports shoe that includes the above-mentioned lateral grip structure of the outsole of a sports shoe designed specifically for women. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The core of this invention is to provide a lateral grip structure for the outsole of athletic shoes specifically designed for women, which helps improve the lateral grip of the shoes and prevents users from losing stability during complex directional changes. Another core aspect of this invention is to provide an athletic shoe that includes the aforementioned lateral grip structure for the outsole specifically designed for women.

[0034] Please refer to Figure 2 , Figure 2 This is a bottom view of the lateral grip structure of the outsole of a women's athletic shoe, specifically designed according to this utility model. This specific embodiment provides a lateral grip structure of the outsole of an athletic shoe specifically designed for women, including:

[0035] The forefoot area 1 has multiple spaced-apart transverse ripples 11. The transverse ripples 11 extend along the length of the athletic shoe 4. The ratio of the total area of ​​all transverse ripples 11 to the area of ​​the forefoot area 1 is X, where X is greater than or equal to 50%.

[0036] The heel region 2 has a particle matrix, and the ratio of the total area of ​​each particle 21 in the particle matrix to the area of ​​the heel region 2 is Y, where Y is less than X.

[0037] The transition zone 3 is located between the forefoot zone 1 and the heel zone 2. The transition zone 3 includes multiple longitudinal ripples 31 arranged in sequence with gradually decreasing ripple size. The longitudinal ripples 31 extend along the width direction of the athletic shoe 4.

[0038] It should be noted that, according to biomechanical data on women's feet, the average female foot length is approximately 225±15mm, and the forefoot area 1 accounts for 62% of the force during the gait cycle. This application is designed and developed specifically for women based on their weight and usage habits. For example, in this application, the total area of ​​each lateral wave 11 can be set to 60% of the area of ​​the forefoot area 1 (i.e., X is 60%), and the total area of ​​each particle 21 can be set to 40% of the area of ​​the heel area 2 (i.e., Y is 40%). Of course, X and Y can also be set to other parameters, but it is necessary to ensure that the proportion of lateral waves 11 in the forefoot area 1 is greater than 50%, and to achieve a differentiated density design between the forefoot area 1 and the heel area 2 (i.e., Y is less than X) to improve the lateral grip F2 of the sole 5. Figure 4 As shown.

[0039] In practical applications, the shape, structure, type, and material of the forefoot area 1, heel area 2, and transition area 3 can be determined according to the actual situation and needs.

[0040] When using the lateral grip structure of the outsole of a women's athletic shoe provided by this invention, the forefoot area 1 has multiple spaced-apart lateral ripples 11, and the ratio of the total area of ​​each lateral ripple 11 to the area of ​​the forefoot area 1 is X, where X is greater than or equal to 50%. The heel area 2 has a particle matrix, and the ratio of the total area of ​​each particle 21 in the particle matrix to the area of ​​the heel area 2 is Y, where Y is less than X. Furthermore, the transition area 3 includes multiple longitudinal ripples 31 arranged in sequence with gradually decreasing ripple size; that is, the transition area 3 is a structural design where the ripples gradually transition to the particles 21. Since the lateral ripples 11 of the forefoot area 1 occupy 50% or more of the area of ​​the forefoot area 1, the unevenness of the lateral ripples 11 generates greater friction, resulting in greater grip for the athletic shoe 4.

[0041] Furthermore, the sole 5 of the sports shoe 4 of this application is a composite pattern including transverse ripples 11, a particle matrix, and longitudinal ripples 31 with gradually decreasing ripple amplitude. The direction of the composite pattern can cover 360°. The ripple deformation of the forefoot area 1 stores energy, and the particle 21 of the heel area 2 releases energy through interlocking. This can effectively increase the friction contact surface of the sole 5 and improve the lateral grip F2 and energy return rate of the sole 5.

[0042] In summary, the lateral grip structure of the outsole of the sports shoe provided by this utility model, which is designed specifically for women, can help improve the lateral grip force F2 of the sports shoe 4 and prevent the user from losing stability during complex directional movements.

[0043] In one embodiment, the ratio of the corrugation depth of the transverse corrugations 11 to the diameter of the particles 21 ranges from 1:1.8 to 1:2.2. The elastic modulus matching formula is: E=0.12h. 2 +1.8 (h is the tread depth), by setting the ratio of the tread depth of the transverse tread 11 to the diameter of the particle 21 to 1:1.8-1:2.2 (preferably 1:2), by reasonably setting the tread depth and the diameter of the particle 21, the friction between the sole 5 and the ground can be effectively enhanced, the grip can be improved, and the grip performance and flexibility of the sole 5 can be optimized.

[0044] In one embodiment, the width of the transverse corrugations 11 ranges from 3mm to 5mm (preferably 4mm), and the spacing between two adjacent transverse corrugations 11 ranges from 2mm to 4mm (preferably 3mm); the diameter of the particles 21 ranges from 4mm to 6mm (preferably 5mm), and the height of the particles 21 ranges from 1.2mm to 1.8mm (preferably 1.5mm).

[0045] In one embodiment, the forefoot area 1, the transition area 3, and the heel area 2 are integrated structural components to facilitate the manufacturing of the device and to improve the anti-slip grip of the forefoot area 1, the transition area 3, and the heel area 2.

[0046] In one embodiment, the one-piece structure includes a rubber component.

[0047] It should be noted that the integrated structure described in this application can be made using a formula of 40% natural rubber, 35% styrene-butadiene rubber, and 25% nano-silica, resulting in a structure with high elasticity. Alternatively, thermoplastic polyurethane can be used to replace part of the rubber, and 3% graphene can be added to improve the thermal conductivity of the integrated structure. In practical applications, the specific materials of the integrated structure can be selected based on the actual situation and requirements.

[0048] In one embodiment, the hardness range of the one-piece structure is 50A-60A. A lower Shore hardness value indicates a softer material, allowing for selection of the hardness of the forefoot area 1, transition area 3, and heel area 2 during practical application.

[0049] In one embodiment, the hardness difference between the forefoot area 1 and the heel area 2 is greater than or equal to 5A. This is to provide different support and cushioning effects in different areas of the sole 5. For example, the hardness of the forefoot area 1 can be set to 50A and the hardness of the heel area 2 can be set to 55A, which helps to improve the rebound rate of the athletic shoe 4 (the rebound rate of this product is ≥65%, while the rebound rate of traditional products is ≤55%). This makes the forefoot area 1 softer and more flexible, which helps to absorb impact and improve flexibility, while the heel area 2 is harder and provides better support and durability. By setting a hardness difference between the forefoot area 1 and the heel area 2, the user's comfort and stability during walking can be improved.

[0050] In one embodiment, the particle 21 includes either a circular particle or a hexagonal honeycomb structure. Circular particles are easier to manufacture, while a hexagonal honeycomb structure can replace circular particles, although both offer similar grip. However, manufacturing the particle 21 as a hexagonal honeycomb structure may increase the cost by approximately 15%. The shape and size of the particle 21 can be customized according to actual conditions and needs.

[0051] In one embodiment, the lateral corrugations 11 include wavy corrugations or sawtooth corrugations. Replacing wavy corrugations with sawtooth corrugations can improve the wear resistance of the forefoot area 1, but may reduce the comfort of the forefoot area 1. The shape and size of the lateral corrugations 11 can be set according to actual conditions and needs.

[0052] To further illustrate the effectiveness of the lateral grip structure of the outsole of the sports shoe designed specifically for women provided by this utility model, the following supplementary explanation is provided.

[0053] In this application, the total area of ​​each transverse corrugation 11 can be set to 60% of the area of ​​the forefoot region 1, and the total area of ​​each particle 21 can be set to 40% of the area of ​​the heel region 2. The width of the transverse corrugation 11 is 4 mm, and the spacing between two adjacent transverse corrugations 11 is 3 mm; the diameter of the particle 21 is 5 mm, and the height of the particle 21 is 1.5 mm. Moreover, this structure is made using a formula of 40% natural rubber + 35% styrene-butadiene rubber + 25% nano-silica, so that the hardness of the forefoot region 1 is set to 50A, and the hardness of the heel region 2 is set to 55A.

[0054] Subsequently, performance comparison tests were conducted on this structure according to the ISO 20344 standard. After the grip performance test, the lateral friction coefficient of this structure was 0.91, an increase of +34% compared to the lateral friction coefficient of the traditional sole 5 (0.68). The 45° stop distance of this structure was 3.2cm, an improvement of 45% compared to the 5.8cm of the traditional sole 5. After the Tekscan system test (i.e., comfort performance test, a high-precision sensing technology for pressure distribution and force measurement), the peak plantar pressure of this structure was reduced by 28%, and after wearing this structure for 2 hours of continuous exercise, the user's fatigue index decreased by 40%. After the Taber abrasion test (i.e., durability performance test, a standard test method widely used to evaluate the abrasion resistance of material surfaces), the mass loss of this structure after 5000 wears was <0.8g, while the mass loss of the traditional sole 5 after 5000 wears was >1.5g, meaning that this structure can effectively improve the durability of sole 5. Furthermore, bending tests on this structure showed that it remained crack-free after 100,000 bends, further demonstrating that the durability of this structure has been effectively improved.

[0055] In addition to the aforementioned lateral grip structure of the outsole of athletic shoes designed specifically for women, this utility model also provides an athletic shoe 4 that includes the lateral grip structure of the outsole of athletic shoes designed specifically for women disclosed in the above embodiments. For the structure of other parts of the athletic shoe 4, please refer to the prior art, which will not be repeated here.
