Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, specifically to a sports shoe sole. Background Technology

[0002] The performance of athletic shoe soles, especially their anti-slip properties and grip, is a key indicator of their functionality. Current technology typically incorporates various patterns and anti-slip bumps on soles to improve slip resistance. However, traditional anti-slip structures have some inherent drawbacks: First, on wet or slippery surfaces or complex terrain (such as mud or sand), the tread grooves are easily clogged by dirt, gravel, and other debris, reducing the effective contact area between the sole and the ground, creating a "sandwich" effect that significantly weakens anti-slip performance and even increases the risk of slipping. Second, common anti-slip bumps are often simple columnar or block-shaped, with sharp edges between their sides and the groove walls. This not only hinders the removal of debris but also easily leads to stress concentration under load, accelerating wear. Utility Model Content

[0003] The purpose of this invention is to provide a sports shoe sole that can simultaneously achieve efficient self-cleaning and excellent anti-slip properties to solve the above-mentioned problems.

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

[0005] A sports shoe sole includes a sole body. The lower end face of the sole body has an anti-slip structure. The anti-slip structure includes a plurality of independently distributed anti-slip protrusions and a network of self-cleaning grooves connecting the anti-slip protrusions. Each anti-slip protrusion is truncated pyramidal in shape with an irregular polygonal top surface and inwardly concave arc-shaped sides. The self-cleaning groove network includes a plurality of transverse main grooves extending laterally along the sole body and a plurality of longitudinal main grooves extending longitudinally along the sole body. The transverse main grooves and the longitudinal main grooves... All grooves are irregular grooves, and they intersect each other to divide the lower end face of the sole body into multiple irregular areas. Each irregular area is provided with a set of anti-slip protrusions. The sides of the anti-slip protrusions are connected to the walls of the transverse main groove and the longitudinal main groove through smooth guide surfaces. The top surfaces of the anti-slip protrusions located at the forefoot and heel of the sole body are provided with several pressure-reducing slits. The width of the pressure-reducing slits extends through the sidewalls of the anti-slip protrusions, and their depth is the same as the height of the anti-slip protrusions.

[0006] Preferably, a sediment collection chamber is formed at part of the intersection of the transverse main trench and the longitudinal main trench, and the depth of the sediment collection chamber is greater than the depth of the self-cleaning trench network.

[0007] Preferably, the radius of curvature of the smooth guide surface is 1-2 mm.

[0008] Preferably, the anti-slip protrusion located on the heel has a greater radius of curvature on the side facing the outer side of the sole body than on the side facing the inner side of the sole body.

[0009] Preferably, the pressure-reducing slit is any one or more of a straight line, a Y-shape, or a cross shape, and its width is 0.3-0.8 mm.

[0010] Preferably, the cross-sectional shape of the anti-slip bump is any one or more of an irregular polygon, a circle, or an ellipse, and each anti-slip bump has a different size.

[0011] Preferably, the width of the transverse main groove and the longitudinal main groove is 1.5-2.5 mm, and the depth is 2-3 mm.

[0012] Preferably, the anti-slip bumps are made of highly elastic and wear-resistant rubber material with a Shore hardness of 55-65A.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] 1. This utility model provides a sports shoe sole, which provides an efficient and continuous channel for the drainage of mud, sand and water through a self-cleaning groove network formed by the interlacing of transverse and longitudinal main grooves. This quickly guides and removes loosened foreign objects from the sole contact surface, effectively preventing groove blockage and ensuring that the sole maintains effective contact with the ground under various complex road conditions, thus maintaining stable and durable anti-slip performance. It is further enhanced by anti-slip protrusions in the shape of truncated pyramids. These protrusions are connected to the groove walls of the main grooves through smooth guide surfaces on their sides. The curved sides and smooth guide surfaces greatly reduce stress concentration, improving the tear resistance and wear resistance life of the protrusions. Furthermore, the smooth guide surface shape generates a pump-like effect when deformed under stress, pushing foreign objects outwards and working synergistically with the main groove network to further enhance the self-cleaning effect.

[0015] 2. This utility model provides a sports shoe sole with pressure-reducing slits on the top surface of the anti-slip protrusions in the forefoot and heel areas, where the greatest impact force is borne. These slits allow for slight deformation of the top of the anti-slip protrusions upon impact with the ground, effectively absorbing and dispersing impact energy and improving wearing comfort. Simultaneously, during actions such as pushing off and braking, the edges of the slits can grip the ground more deeply, providing multi-angle traction and enhancing flexibility and stability during movement.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example

[0021] Please refer to Figures 1 to 2 As shown, this utility model discloses a sports shoe sole, including a sole body 1, which includes a forefoot part 11, an arch part 12 and a heel part 13 from front to back.

[0022] The lower end face (i.e. the ground surface) of the sole body 1 is provided with an anti-slip structure, which includes several independently distributed anti-slip protrusions 2 and a self-cleaning groove network 3 connecting each anti-slip protrusion 2.

[0023] The anti-slip bump 2 is truncated pyramidal in shape, meaning that the area of ​​its top surface 21 is smaller than the area where its bottom surface connects to the sole body 1. The cross-sectional shape of the anti-slip bump 2 can be any one or more of the following: an irregular polygon, a circle, or an ellipse. Each anti-slip bump 2 has a different size. The side surface 22 of the anti-slip bump 2 is an inwardly concave arc surface, rather than a vertical plane. This unique arc-shaped side surface 22 design allows the anti-slip bump 2 to produce better deformation when subjected to force, thereby enhancing grip.

[0024] The self-cleaning groove network 3 includes several transverse main grooves 31 extending laterally (i.e., in the width direction) along the sole body 1 and several longitudinal main grooves 32 extending longitudinally (i.e., in the length direction) along the sole body 1. Both the transverse main grooves 31 and the longitudinal main grooves 32 are irregular grooves, adapted to the structure of the anti-slip protrusions 2. The transverse main grooves 31 and the longitudinal main grooves 32 intersect each other, dividing the lower end face of the sole body 1 into multiple irregular areas. Each irregular area is provided with a set of anti-slip protrusions 2, which can be arranged in a matrix or other regular form.

[0025] To achieve efficient self-cleaning and smooth stress transfer, the side 22 of the anti-slip protrusion 2 is seamlessly connected to the walls of the transverse main groove 31 and the longitudinal main groove 32 via a smooth guide surface 4. The radius of curvature of the smooth guide surface is 1-2 mm, and in this embodiment, the radius of curvature R of the smooth guide surface 4 is preferably 1.5 mm. The smooth guide surface 4 allows foreign objects such as mud and water to be smoothly guided along the surface into the main groove and discharged, while avoiding stress concentration at sharp corners and extending the life of the sole.

[0026] A sediment collection chamber 5 is formed at the partial intersection of the transverse main trench 31 and the longitudinal main trench 32. The depth of the sediment collection chamber 5 is greater than the depth of the transverse main trench 31 and the longitudinal main trench 32. In this embodiment, the depth of the main trench is 2.5 mm, while the depth of the sediment collection chamber 5 is 4 mm. The deepened design of the sediment collection chamber 5 can provide temporary storage space for fine sediment that is difficult to discharge instantly, preventing it from clogging at the intersection of the trenches, thereby ensuring the long-term effectiveness of the self-cleaning network.

[0027] Several pressure-reducing slits 6 are provided on the top surface 21 of the anti-slip protrusions 2 on the forefoot part 11 and the heel part 13 of the sole body 1 to further improve wearing comfort and dynamic grip performance. The width of the pressure-reducing slits 6 extends through the side wall 22 of the anti-slip protrusion 2, and its depth is the same as the height of the anti-slip protrusion 2, that is, it extends from the top surface to the smooth guide surface 4 or the bottom of the groove.

[0028] The pressure-reducing slots can be any one or more of the following shapes: straight, Y-shaped, or cross-shaped, and their width is 0.3-0.8mm. When the foot hits the ground, the pressure-reducing slots 6 allow the top of the anti-slip protrusions 2 to deform slightly, effectively absorbing impact energy and acting as a buffer. When pushing off the ground, the edges of the slots can also provide additional gripping edges, enhancing propulsion.

[0029] Considering that the outer side of the heel usually lands first and is accompanied by an outward movement in human gait, the anti-slip protrusion 2 located on the heel 13 has a larger radius of curvature on the side facing the outer side of the sole body 1 than on the side facing the inner side of the sole body 1. This asymmetrical structure makes it smoother when the outer side of the heel lands, and provides stronger support and grip when transitioning to full-length landing, thus improving movement stability.

[0030] The width of the transverse main groove and the longitudinal main groove is 1.5-2.5mm, and the depth is 2-3mm. In this embodiment, the width of the transverse main groove 31 and the longitudinal main groove 32 is 2mm, and the depth is 2.5mm. The anti-slip protrusion 2 is made of a highly elastic and wear-resistant rubber material (such as a mixture of natural rubber and butadiene rubber) with a Shore hardness of 55-65A. This hardness range ensures that the anti-slip protrusion 2 has good elasticity, grip, and wear resistance.

[0031] The working principle of this embodiment is as follows:

[0032] When the wearer walks or runs, the sole body 1 contacts the ground, and the anti-slip bumps 2 provide the main grip. Their curved sides and smooth guide surfaces 4 allow debris (mud, water, sand) around the anti-slip bumps 2 to be easily squeezed and guided into the self-cleaning groove network 3 during stepping. As the foot lifts, the groove network provides a smooth discharge channel for debris, while the pressure-reducing slits 6 located in high-impact areas effectively absorb impact and increase the number of instantaneous grip teeth through their opening and closing. The entire system works in tandem to achieve a combination of continuous anti-slip, effective cushioning, and efficient self-cleaning.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
