Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, and in particular to an anti-slip structure for shoe soles and a shoe sole. Background Technology
[0002] Shoe sole anti-slip design reduces the risk of slipping by increasing the friction between the sole and the ground, thereby improving the shoe's grip. Currently, anti-slip sole design addresses this through both materials and structure. Structurally, conventional anti-slip sole designs involve incorporating anti-slip treads or raised bumps. Treads increase the roughness of the sole surface, generating greater friction when the sole contacts the ground; however, if the treads are too shallow or the material too hard, their anti-slip effect will be significantly reduced. Anti-slip raised bumps, compared to treads, offer better anti-slip performance in certain situations. Their design is typically more three-dimensional, penetrating even tiny uneven areas of the ground like "claws," providing stronger grip and effectively increasing the contact area and traction between the sole and the ground. As a key factor in shoe anti-slip performance, improving the grip of anti-slip raised bumps is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] Example 1
[0029] like Figs. 1-3 As shown, the sole 1 of this embodiment is equipped with a sole anti-slip structure. The sole anti-slip structure includes a plurality of first anti-slip protrusions 2 distributed on the forefoot area 11 of the sole 1. The side of the first anti-slip protrusion 2 facing the heel area 12 is configured as a first inclined surface 21 that is inclined from the bottom of the sole 1 towards the heel area 12. A plurality of first anti-slip teeth 22 are distributed on the first inclined surface 21.
[0030] The first ramp 21 can penetrate deeper into the ground like a shovel to enhance grip, and the first anti-slip teeth 22 can assist in improving the grip of the first anti-slip protrusion 2. During movement, they can effectively bite the ground like teeth to enhance grip, thereby enhancing the overall grip of the first anti-slip protrusion 2. When the shoe slides backward, the better grip of the first anti-slip protrusion 2 reduces the possibility of falling backward.
[0031] In this embodiment, the first anti-slip protrusion 2 is a V-shaped block with its opening facing the rear foot area 12. Its cross-section is V-shaped, which can improve the anti-slip ability of the first anti-slip protrusion 2 and reduce the possibility of the sole 1 slipping backward.
[0032] It is understood that the first anti-slip protrusion 2 of this utility model can also be other shapes, such as three-dimensional graphics with a cross-section of triangle, square, rectangle, parallelogram, arc, regular shape or irregular shape.
[0033] The inclination angle of the first inclined surface 21 of the embodiment is based on the horizontal distance of the first inclined surface 21, and the horizontal distance is too large, so that the finished product cannot be demolded, and therefore, under the premise of ensuring the ground grabbing performance of the first anti-skid protrusion 2, the first inclined surface 21 and the bottom surface of the sole 1 preferably form an included angle a of 65°-70°. It can be understood that if the first anti-skid protrusion 2 is made by means of 3D printing or the like, there is no demolding problem, and therefore the above problem does not need to be considered, and the inclination angle of the first inclined surface 21 can be determined according to the actual application scene and requirements.
[0034] The height of the first anti-skid tooth 22 of the embodiment is preferably 0.5-1 mm, and the shape of the first anti-skid tooth 22 is not limited, and can be spherical, conical, cylindrical, pyramidal, prismatic, regular or irregular.
[0035] In order to improve the production efficiency and meet the batch production, the first anti-skid protrusion 2 of the embodiment is formed by mold pouring, and the material of the first anti-skid protrusion 2 is rubber, polyurethane, TPU or EVA. In actual production, in order to improve the bonding strength of the first anti-skid protrusion 2 and the sole 1, the two can be integrally poured and formed.
[0036] Embodiment two
[0037] As shown in Figs. 4-6 The sole 1 of the embodiment is provided with a sole anti-skid structure, which comprises a plurality of second anti-skid protrusions 3 distributed in the rear metatarsal area 12 of the bottom surface of the sole 1. The side vertical surface of the second anti-skid protrusion 3 towards the forefoot area 11 is configured as a second inclined surface 31 inclined from the bottom surface of the sole 1 to the forefoot area 11, and a plurality of second anti-skid teeth 32 are distributed on the second inclined surface 31.
[0038] The second inclined surface 31 can better penetrate the ground like a shovel to enhance the ground grabbing force, and the second anti-skid tooth 32 can assist in improving the ground grabbing effect of the second anti-skid protrusion 3, which can effectively bite the ground like teeth during movement to enhance the ground grabbing force, thereby enhancing the overall ground grabbing force of the second anti-skid protrusion 3. When the shoes slide forward, the second anti-skid protrusion 3 can better grab the ground to reduce the possibility of falling forward.
[0039] The second anti-skid protrusion 3 of the embodiment is a V-shaped block with an opening facing the forefoot area 11, and the cross section is V-shaped, which can improve the anti-skid ability of the second anti-skid protrusion 3 and reduce the possibility of the sole 1 slipping forward.
[0040] It can be understood that the second anti-skid protrusion 3 of the utility model can also be other shapes, such as a three-dimensional figure with a triangular, square, rectangular, parallelogram, arcuate, arc, regular or irregular cross section.
[0041] The inclination angle of the second inclined surface 31 of the embodiment is based on the horizontal distance of the second inclined surface 31, and the horizontal distance is too large to demould the finished product, so that the second inclined surface 31 and the bottom surface of the sole 1 preferably form an included angle b of 65°-70° under the premise of ensuring the ground holding performance of the second anti-skid protrusion 3. It can be understood that if the second anti-skid protrusion 3 is made by means of 3D printing, there is no demoulding problem, and the above problem does not need to be considered, and the inclination angle of the second inclined surface 31 can be determined according to the actual application scene and requirements.
[0042] The height of the second anti-skid tooth 32 of the embodiment is preferably 0.5-1mm, and the shape of the second anti-skid tooth 32 is not limited and can be spherical, conical, cylindrical, pyramidal, prismatic, regular or irregular.
[0043] The material of the second anti-skid protrusion 3 of the embodiment is rubber, polyurethane, TPU or EVA, and is formed by mold pouring to improve production efficiency and meet the requirements of batch production. Of course, the second anti-skid protrusion 3 can also be integrally poured with the sole 1 to enhance the bonding strength of the two.
[0044] Embodiment three
[0045] As shown in Fig. 7 The sole 1 of the embodiment is provided with a sole anti-skid structure, which includes a plurality of first anti-skid protrusions 2 distributed in the forefoot area 11 of the bottom surface of the sole 1 and a plurality of second anti-skid protrusions 3 distributed in the rearfoot area 12 of the bottom surface of the sole 1. The first anti-skid protrusion 2 is the same as that of embodiment one, and the second anti-skid protrusion 3 is the same as that of embodiment two, which will not be described here. Through the ground holding force of the first anti-skid protrusion 2 and the second anti-skid protrusion 3, the possibility of falling forward and backward can be reduced, so that the sole 1 of the embodiment has good anti-skid performance, thereby improving the safety of wearing.
[0046] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the utility model in form and detail without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
