FIELD
[0001] The present invention relates generally to the field of footwear, and more particularly, to an anti-slip shoe sole.
BACKGROUND
[0002] In the shoe-making industry, many manufacturers have been committed to solve the sliding problem of soles. Therefore, anti-slip design has generally become a basic element of soles design. At present, protrusions or grooves formed in various patterns are generally distributed on a shoe sole, to achieve the anti-slip effect of the shoe sole. However, during the usage of such shoe sole, only one side of an extended end of each protrusion is capable of contacting the ground, and only protrusions distributed on forefoot and heel areas of the shoe sole generally contact the ground, so there is a small contact area, with a poor anti-slip effect. In addition, on a rainy day, water in the grooves is difficult to be drained, so that the anti-slip effect of such shoe sole is even worse, and such shoe sole is apt to slip on wet ground.
SUMMARY
[0003] An objective of the present invention is to provide an anti-slip shoe sole which can increase the contact area between the shoe sole and the ground and facilitate the water to be drained, to improve the anti-slip and drainage effect of the shoe sole.
[0004] To achieve the above objective, the following technical solutions are provided. An anti-slip shoe sole is provided, including a toe end and a heel end, wherein a plurality of anti-slip strips are disposed in parallel between the toe end and the heel end, and sequentially arranged in parallel from the toe end to the heel end, a drainage groove is formed between two adjacent anti-slip strips, and the anti-slip strips are obliquely disposed in the same arranging direction of the plurality of anti-slip strips.
[0005] The anti-slip strips of the anti-slip shoe sole are sequentially arranged in parallel from the toe end to the heel end, and obliquely disposed in the same arranging direction of the plurality of anti-slip strips, forming a structure of pleated web, and achieving a similar effect with that of web feet of a gecko. When a user wearing shoes with the shoe soles is walking, the plurality of anti-slip strips can extend in the inclined direction under gravity, so all the anti-slip strips from the toe end to the heel end can contact the ground, rather than only the anti-slip strips distributed on forefoot and heel areas contact the ground. In this way, the contact area between the anti-slip strips and the ground is increased greatly. In addition, two adjacent anti-slip strips can press against and overlap one another, so that the water is easy to be drained from both ends of the drainage channel, improving the anti-slip and drainage effect of the shoe sole greatly.
[0007] Further, the anti-slip strip is provided with a root part and a ground-touching part, and the anti-slip strip is gradually closer to the toe end from the root part to the ground-touching part.
[0008] Further, the anti-slip strip has a V-shaped structure with an opening toward the toe end. The plurality of V-shaped anti-slip strips is arranged in parallel between the toe end and the heel end to form a structure of pleated web and achieve a similar effect with that of web feet of a gecko. In this way, the grip of the anti-slip shoe sole can be increased, to further improve the anti-slip effect of the anti-slip shoe sole.
[0009] Further, a first side surface and a second side surface opposite to the first side surface are connected between the root part and ground-touching part, the first side surface is close to the toe end, the second side surface is away from the toe end, the first side surface is a flat surface, and the second side surface is a curved surface. The anti-slip strip is gradually closer to the toe end from the root part to the ground-touching part, the first side surface is closer to the toe end, and the second side surface is further away from the toe end, so that during walking, the ground-touching part contacts the ground firstly, and then the second side surface contacts the ground under gravity. Since the first side surface is a flat surface, and the second side surface is a curved surface, the anti-slip strips are more likely to extend in the inclined direction, i.e., a direction towards the toe end, to avoid bending, to further improve the anti-slip effect of the anti-slip shoe sole.
[0010] Further, the anti-slip strip is provided with a root part and a ground-touching part, and the anti-slip strip is gradually closer to the heel end from the root part to the ground-touching part.
[0011] Further, the anti-slip strip has a V-shaped structure with an opening toward the heel end. The plurality of V-shaped anti-slip strips is arranged in parallel between the toe end and the heel end to form a structure of pleated web and achieve a similar effect with that of web feet of a gecko. In this way, the grip of the anti-slip shoe sole can be increased, to further improve the anti-slip effect of the anti-slip shoe sole.
[0012] Further, a first side surface and a second side surface opposite to the first side surface are connected between the root part and ground-touching part, the first side surface is close to the toe end, the second side surface is away from the toe end, the first side surface is a curved surface, and the second side surface is a flat surface. The anti-slip strip is gradually closer to the heel end from the root part to the ground-touching part, the first side surface is further away from the heel end, and the second side surface is closer to the heel end, so that during walking, the ground-touching part contacts the ground firstly, and then the first side surface contacts the ground under gravity. Since the first side surface is a curved surface, and the second side surface is a flat surface, the anti-slip strips are more likely to extend in the inclined direction, i.e., a direction towards the heel end, to avoid bending, to further improve the anti-slip effect of the anti-slip shoe sole.
[0013] Further, the anti-slip strip has a thickness gradually decreasing from the root part to the ground-touching part. The size of the opening of the drainage channel gradually increases from the root part to the ground-touching part, so that the shoe sole has a better drainage effect. In addition, the ground-touching part of the anti-slip strip is softer due to its small thickness, so during walking, the anti-slip strip is not only more likely to extend in the slope direction, but also fit the rough ground better, to further improve the contact area between anti-slip strip and ground and achieve a similar effect with that of web feet of a gecko. Moreover the root part has a larger thickness, so that the anti-slip strip is unlikely to fall away from the shoe sole, which extends the service life of anti-slip shoe sole.
[0014] Further, the ground-touching part is provided with a nubuck layer or a fluff layer, to increase the friction coefficient between the ground-touching part and ground, to further improve the anti-slip effect of the anti-slip shoe sole. Further, the anti-slip shoe sole also includes a base portion, the plurality of anti-slip strips are arranged on the base portion, and the plurality of anti-slip strips are positioned to the base portion at an oblique angle α, where 5°≤α≤ 80°.
[0016] In the anti-slip shoe sole according to the present invention, the anti-slip strips are sequentially arranged in parallel from the toe end to the heel end, and obliquely disposed in the same arranging direction of the plurality of anti-slip strips, forming a structure of pleated web, and achieving a similar effect with that of web feet of a gecko. When a user wearing shoes with the shoe soles is walking, the plurality of anti-slip strips can extend in the inclined direction under gravity, so all the anti-slip strips from the toe end to the heel end can contact the ground, rather than only the anti-slip strips distributed on forefoot and heel areas contact the ground. In this way, the contact area between the anti-slip strips and the ground is increased greatly. In addition, two adjacent anti-slip strips can press against and overlap one another, so that the water is easy to be drained from both ends of the drainage channel, improving the anti-slip and drainage effect of the shoe sole greatly.

DETAILED DESCRIPTION
[0019] The present invention is further described in detail below in combination with the drawings and specific embodiments, but not regarded as the limitation of the present invention.
[0020] As shown in FIG. 1 and FIG. 2, an anti-slip shoe sole is provided, including a toe end 10 and a heel end 20. A plurality of anti-slip strips 30 are disposed in parallel between the toe end 10 and the heel end 20, and sequentially arranged in parallel from the toe end 10 to the heel end 20, a drainage groove 40 is formed between two adjacent anti-slip strips 30, and the anti-slip strips 30 are obliquely disposed in the same arranging direction of the plurality of anti-slip strips 30.
[0021] The anti-slip strips 30 of the anti-slip shoe sole are sequentially arranged in parallel from the toe end 10 to the heel end 20, and obliquely disposed in the same arranging direction of the plurality of anti-slip strips 30, forming a structure of pleated web, and achieving a similar effect with that of web feet of a gecko. When a user wearing shoes with the shoe soles is walking, the plurality of anti-slip strips 30 can extend in the inclined direction under gravity, so all the anti-slip strips 30 from the toe end 10 to the heel end 20 can contact the ground, rather than only the anti-slip strips 30 distributed on forefoot and heel areas contact the ground. In this way, the contact area between the anti-slip strips 30 and the ground is increased greatly. In addition, two adjacent anti-slip strips 30 can press against and overlap one another, so that the water is easy to be drained from both ends of the drainage channel, improving the anti-slip and drainage effect of the shoe sole greatly.
[0022] In this embodiment, as shown in FIG. 2, the anti-slip shoe sole also includes a base portion 50. The plurality of anti-slip strips 30 are arranged on the base portion 50, and the plurality of anti-slip strips 30 are positioned at an oblique angle α with respect to the base portion 50, where 5°≤α≤80°. The oblique angle α may be set for example, as 15°≤α≤ 80°, according to practical requirements.
[0023] As shown in FIG. 1, an inner lateral side 60 and an outer lateral side 70 are connected between the toe end 10 and the heel end 20. Both ends of the anti-slip strip 30 are connected to the inner lateral side 60 and the outer lateral side 70 respectively. And the anti-slip strip 30 is made of a soft rubber material, so that the anti-slip strip 30 is not only easy to extend in the slope direction, but also plays a role in abrasion resistance.
[0024] As shown in FIG. 1 and FIG. 2, the anti-slip strip 30 is provided with a root part 310 and a ground-touching part 320. The root part 310 is connected to the base portion 50. The anti-slip strip 30 is gradually closer to the toe end 10 from the root part 310 to the ground-touching part 320. The anti-slip strip 30 has a V-shaped structure with an opening toward the toe end 10. The plurality of V-shaped anti-slip strips 30 is arranged in parallel between the toe end and the heel end to form a structure of pleated web and achieve a similar effect with that of web feet of a gecko. In this way, the grip of the anti-slip shoe sole can be increased, to further improve the anti-slip effect of the anti-slip shoe sole. The protection ridge can be designed to have a structure composed of a plurality of V-shaped structures connected end to end, such as a W-shaped or line-shaped structure, according to practical requirements.
[0025] As shown in FIG. 2, a first side surface 330 and a second side surface 340 opposite to the first side surface 330 are connected between the root part 310 and ground-touching part 320, the first side surface 330 is close to the toe end 10, the second side surface 340 is away from the toe end 20, the first side surface 330 is a flat surface, and the second side surface 340 is a curved surface. The anti-slip strip 30 is gradually closer to the toe end 10 from the root part 310 to the ground-touching part 320, the first side surface 330 is closer to the toe end 10, and the second side surface 340 is further away from the toe end 10, so that during walking, the ground-touching part 320 contacts the ground firstly, and then the second side surface 340 contacts the ground under gravity. Since the first side surface 330 is a flat surface, and the second side surface 340 is a curved surface, the anti-slip strips 30 are more likely to extend in the inclined direction, i.e., a direction towards the toe end 10, to avoid bending, to further improve the anti-slip effect of the anti-slip shoe sole.
[0026] As shown in FIG. 2, the anti-slip strip 30 has a thickness gradually decreasing from the root part 310 to the ground-touching part 320. The size of the opening of the drainage channel 40 gradually increases from the root part 310 to the ground-touching part 320, so that the shoe sole has a better drainage effect. In addition, the ground-touching part 320 of the anti-slip strip 30 is softer due to its small thickness, so during walking, the anti-slip strip 30 is not only more likely to extend in the slope direction, but also fit the rough ground better, to further improve the contact area between anti-slip strip 30 and ground and achieve a similar effect with that of web feet of a gecko. Moreover the root part 310 has a larger thickness, so that the anti-slip strip 30 is unlikely to fall away from the shoe sole, which extends the service life of anti-slip shoe sole.
[0027] The ground-touching part is provided with a nubuck layer (not shown) or a fluff layer (not show), to increase the friction coefficient between the ground-touching part 320 and ground, to further improve the anti-slip effect of the anti-slip shoe sole.
[0028] As shown in FIG. 3 and FIG. 4, in this embodiment, which is different from the above embodiment, the slope direction of anti-slip strip 30 is positioned so that the anti-slip strip 30 is gradually closer to the heel end 20 from the root part 310 to the ground-touching part 320. The anti-slip strip 30 has a V-shaped structure with an opening toward the heel end 20. The plurality of V-shaped anti-slip strips 30 is arranged in parallel between the toe end 10 and the heel end 20 to form a structure of pleated web and achieve a similar effect with that of web feet of a gecko. In this way, the grip of the anti-slip shoe sole can be increased, to further improve the anti-slip effect of the anti-slip shoe sole.
[0029] As shown in FIG. 4, in this embodiment, a first side surface 330 and a second side surface 340 opposite to the first side surface 330 are connected between the root part 310 and ground-touching part 320, the first side surface 330 is close to the toe end 10, the second side surface 340 is away from the toe end 20, the first side surface 330 is a curved surface, and the second side surface 340 is a flat surface. During walking, the ground-touching part 320 contacts the ground firstly, and then the first side surface 330 contacts the ground under gravity. Since the first side surface 330 is a curved surface, and the second side surface 340 is a flat surface, the anti-slip strips 30 are more likely to extend in the inclined direction, i.e., a direction towards the heel end 20, to avoid bending, to further improve the anti-slip effect of the anti-slip shoe sole.
[0030] In the above embodiments, the anti-slip strips 30 are sequentially arranged in parallel from the toe end 10 to the heel end 20, and obliquely disposed in the same arranging direction of the plurality of anti-slip strips 30, forming a structure of pleated web, and achieving a similar effect with that of web feet of a gecko. When a user wearing shoes with the shoe soles is walking, the plurality of anti-slip strips 30 can extend in the inclined direction under gravity, so all the anti-slip strips 30 from the toe end 10 to the heel end 20 can contact the ground, rather than only the anti-slip strips 30 distributed on forefoot and heel areas contact the ground. In this way, the contact area between the anti-slip strips 30 and the ground is increased greatly. In addition, two adjacent anti-slip strips 30 can press against and overlap one another, so that the water is easy to be drained from both ends of the drainage channel 40, improving the anti-slip and drainage effect of the shoe sole greatly.

In order to make the description concise, all possible combinations of all the technical features in the above embodiments are not described one by one. However, as long as there is no contradiction in the combinations of these technical features, all the combinations should be considered within the scope of the disclosure contained in the present description.
