Description

Technical Field

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

[0002] In the field of athletic footwear, slip resistance is one of the key indicators for evaluating its functionality, especially in complex road conditions such as wetness and mud. Current athletic shoe outsole slip resistance designs mostly employ single raised patterns, such as herringbone patterns, wave patterns, or simple granular raised textures. While these designs improve friction to some extent, they still have the following inherent drawbacks:

[0003] First, traditional single anti-slip patterns cannot simultaneously meet the multi-directional anti-slip needs of the forefoot and heel, as well as the instantaneous grip needs of the toe during specific movements (such as pushing off and starting). Furthermore, when subjected to multi-directional forces (such as sudden stops and turns), their ability to guide and drain mud and water is limited, which can easily lead to a "water film effect," causing a layer of water to form between the sole and the ground, significantly reducing grip.

[0004] Secondly, existing anti-slip strips are prone to insufficient or excessive rigid deformation when subjected to force, especially when subjected to combined vertical and shear stress, resulting in a reduced contact area or stress concentration, which affects the stability of the anti-slip effect. Utility Model Content

[0005] The purpose of this invention is to provide a non-slip sports shoe that can provide zoned anti-slip, cope with multi-directional force, and quickly drain water and mud to effectively break the water film, in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-slip athletic shoe includes an upper and a sole. The upper is fixed to the sole. The bottom surface of the sole has a main anti-slip area and a secondary anti-slip area. The main anti-slip area is located at the forefoot and heel of the sole and includes several serpentine anti-slip ridges arranged along the width of the sole. A serpentine groove is provided between two adjacent groups of serpentine anti-slip ridges. The top surface of each serpentine anti-slip ridge has several inverted V-shaped drainage grooves along its length. The left and right ends of each group of inverted V-shaped drainage grooves penetrate the left and right sidewalls of the serpentine anti-slip ridge. The inverted V-shaped drainage grooves divide the serpentine anti-slip ridge into several anti-slip blocks. The top surface of each anti-slip block has a pressure-reducing slit along its width. The secondary anti-slip area is located at the toe of the sole and includes several arc-shaped anti-slip ridges arranged along the length of the sole. The arc-shaped anti-slip ridges have integrally formed bidirectional serrated protrusions, and the tooth surfaces of the bidirectional serrated protrusions have transverse patterns.

[0008] Preferably, the arch area of ​​the sole is provided with a marking area, which includes size markings, brand markings, and anti-slip performance markings.

[0009] Preferably, the arch area of ​​the sole and the left and right sides of the marking area are provided with arc-shaped guide slopes, and the bottom end of the arc-shaped guide slopes extends to the side wall of the sole.

[0010] Preferably, the cross-sectional shape of the pressure relief seam is any one or more of V-shape, U-shape, or rectangle.

[0011] Preferably, the depth of the pressure relief groove is 1 / 3 to 1 / 2 of the height of the anti-slip protrusion.

[0012] Preferably, the opening angle of the inverted V-shaped drainage groove is 90°-150°.

[0013] Preferably, the sole is made of a hardness rubber material, wherein the Shore hardness of the forefoot and heel is 60-65A, and the Shore hardness of the toe is 55-60A.

[0014] Preferably, the surfaces of the serpentine anti-slip ridges and the arc-shaped anti-slip ridges are covered with a wear-resistant rubber layer.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model provides an anti-slip sports shoe. By setting a main anti-slip zone and an auxiliary anti-slip zone on the bottom surface of the shoe sole, functional zoning is achieved. The serpentine anti-slip ridges and serpentine grooves in the main anti-slip zone form a multi-directional tortuous drainage channel, which can quickly discharge liquid and mud between the sole and the ground from multiple directions, effectively breaking the water film. The inverted V-shaped drainage groove on the top surface of the serpentine ridge further disperses and discharges the water flow laterally. The design of its two ends penetrating the side wall ensures that the drainage path is unobstructed, which greatly improves the anti-slip performance on wet and slippery surfaces.

[0017] 2. This utility model provides an anti-slip sports shoe. The auxiliary anti-slip area at the toe of the shoe adopts an arc-shaped anti-slip ridge along the length direction and is integrally formed with bidirectional serrated protrusions. It provides strong one-way and multi-way anti-slip ability for actions such as pushing forward and starting. The transverse texture on the tooth surface of the serrated protrusion further increases the friction at the micro level, ensuring that the toe of the shoe has reliable grip performance in any direction of movement.

[0018] 3. This utility model provides an anti-slip sports shoe. The inverted V-shaped drainage groove divides the serpentine anti-slip ridges into independent anti-slip bumps, allowing each bump to undergo slight independent deformation under pressure, better conforming to the ground and increasing the effective contact area. The pressure-relief seams on the top surface of the anti-slip bumps open moderately under pressure, generating an edge adsorption effect, further enhancing grip. At the same time, this structure effectively releases the stress inside the bumps, preventing excessive wear caused by stress concentration and extending the service life of the sole.

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.

[0022] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Example

[0024] Please refer to Figures 1 to 2 As shown, this utility model discloses an anti-slip sports shoe, including an upper 1 and a sole 2. The upper 1 is fixed to the sole 2 by stitching or gluing. The bottom surface of the sole 2 is divided into a forefoot section 21, a heel section 22, an arch section 23, and a toe section 24 according to ergonomics and usage requirements. The bottom surface of the sole 2 is provided with a main anti-slip zone 3 and a secondary anti-slip zone 4.

[0025] The main anti-slip zone 3 is located in the two main load-bearing and force-generating areas of the sole 2: the forefoot part 21 and the heel part 22. This area includes several serpentine anti-slip ridges 31 arranged parallel to each other along the width direction (i.e., roughly laterally) of the sole 2. The serpentine anti-slip ridges 31 extend in a continuous wave-like or S-shaped meandering manner. The direction of their peaks and troughs can provide multi-directional anti-slip resistance. A serpentine groove 32 matching the shape is formed between two adjacent sets of serpentine anti-slip ridges 31, which together constitute the main drainage and mud removal channels of the main anti-slip zone 3.

[0026] On the top surface of each serpentine anti-slip ridge 31, several inverted V-shaped drainage grooves 33 are spaced apart along its length. The opening angle of the inverted V-shaped drainage grooves is 90°-150°. The left and right ends of each inverted V-shaped drainage groove 33 penetrate the left and right side walls of the serpentine anti-slip ridge 31, so that liquids and silt can not only be discharged downward from the bottom of the groove, but also be quickly discharged from the side, forming a three-dimensional drainage network.

[0027] The inverted V-shaped drainage channel 33 divides the continuous serpentine anti-slip ridges 31 into multiple independent anti-slip ridges 34. Each anti-slip ridge 34 has a pressure-reducing slit 35 on its top surface along its width. The cross-sectional shape of the pressure-reducing slit is any one or more of V-shape, U-shape, or rectangle, and the depth of the pressure-reducing slit is 1 / 3 to 1 / 2 of the height of the anti-slip ridge. When the anti-slip ridge 34 is compressed, the pressure-reducing slit 35 can open, increasing edge grip and releasing internal stress. At the same time, it can break the water film when in contact with a wet and slippery surface, producing an adsorption effect.

[0028] The auxiliary anti-slip zone 4 is located at the toe section 24 of the sole 2, and includes several arc-shaped anti-slip ridges 41 arranged along the length direction (i.e., approximately longitudinally) of the sole 2. The convex surface of the arc-shaped anti-slip ridges 41 faces the toe direction. On each arc-shaped anti-slip ridge 41, multiple bidirectional serrated protrusions 42 are integrally formed. The bidirectional serrated protrusions 42 have inclined tooth surfaces pointing in both the toe and heel directions, thereby providing effective anti-slip capability for both forward and backward movements. On the tooth surface of each serrated protrusion 42, transverse grooves 43 (the groove direction is perpendicular to the extension direction of the serrations) are also formed. These micro-grooves can further increase the surface roughness and improve the instantaneous grip.

[0029] A marking area 5 is provided on the arch part 23 of the sole 2. The marking area 5 is formed on the surface of the sole 2 by means of recess or protrusion. The marking area 5 contains a size marking 51, a brand marking 52, and an anti-slip performance marking 53 for indicating the characteristics of this shoe.

[0030] On the arch area 23, located on both sides of the marking area 5, there is an arc-shaped guide slope 6. The arc-shaped guide slope 6 slopes smoothly from the inner highest point of the sole 2 towards the side wall of the sole 2, and its bottom end extends to and smoothly connects with the side wall of the sole 2. This structure can quickly guide and throw away water and mud splashed into the arch area to the side, keeping the sole clean and stable.

[0031] The sole 2 is made of one-piece molded rubber with different hardness. To optimize performance, different areas of the sole 2 use different Shore hardness: the forefoot 21 and heel 22, which bear the main weight and impact, have a rubber hardness of 63A (ranging from 60 to 65A); the toe 24, which requires more emphasis on grip and fit, has a rubber hardness of 58A (ranging from 55 to 60A). This gradient hardness design ensures both support and wear resistance, as well as flexibility and grip.

[0032] The curvature of the serpentine anti-slip ridge 31 and the arc-shaped anti-slip ridge 41 is adapted to the overall outer contour of the sole. The surfaces of the serpentine anti-slip ridge 31 and the arc-shaped anti-slip ridge 41 are also covered with a layer of wear-resistant rubber (not shown separately in the figure). This wear-resistant rubber layer can be achieved through secondary injection molding or patching process, and its wear resistance is better than that of the base rubber.

[0033] A brief description of the working principle of this embodiment:

[0034] When the wearer walks or exercises on a wet or slippery surface:

[0035] The serpentine groove 32 and the inverted V-shaped drainage groove 33 of the main anti-slip zone 3 form a rapid drainage and mud removal network, which quickly displaces the interface medium.

[0036] The anti-slip protrusions 34 and the pressure relief seams 35 on them dynamically deform under pressure, increasing the contact area and generating a local vacuum adsorption effect.

[0037] The bi-directional serrated protrusions 42 and their transverse grooves 43 in the auxiliary anti-slip zone 4 provide a powerful longitudinal locking function when pushing off the ground and starting.

[0038] The curved drainage slope 6 in the arch area guides laterally intruding fluid away from the sole; the zoned hardness design ensures that the sole maintains optimal grip and support balance in all movement postures.

[0039] 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.
