Description

Technical Field

[0001] This utility model belongs to the field of shoe soles, specifically relating to a shoe sole structure that increases friction. Background Technology

[0002] Currently, most shoes on the market increase friction with the ground by incorporating grooves in the sole, thus achieving a non-slip effect and improving safety when walking on wet, slippery surfaces. However, soles with only grooves are still relatively flat, resulting in a large contact area with the ground. This reduces the coefficient of friction between the shoe and the ground, and consequently, the friction between the shoe and the ground. When running, people need to generate greater friction to obtain greater propulsion. Simply increasing friction with grooves may provide sufficient friction for normal walking, but insufficient friction for running, leading to the risk of slipping.

[0003] In existing technologies, such as patent document CN203505718U, an anti-slip shoe sole is disclosed. This anti-slip texture structure, formed by first, second, and third longitudinal grooves and transverse grooves, is used on the sole to increase the friction between the sole and the ground, thus achieving an anti-slip effect. However, the friction provided by the grooved anti-slip texture structure is relatively small, and the risk of slipping still exists when running. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a shoe sole mechanism that increases friction. By using staggered first and second anti-slip protrusions, the contact area between the shoe and the ground is reduced, making the sole rougher and thus increasing the coefficient of friction between the shoe and the ground, enabling the shoe to provide sufficient friction when people run.

[0005] This invention is implemented as follows: A shoe sole structure that increases friction is disposed at the bottom of a shoe, including a first sole and a second sole disposed vertically. The first sole is connected to the shoe body, and the second sole is in contact with the ground. A shoe cavity is formed between the first sole and the shoe body to accommodate a human foot. The second sole includes a sole plate adapted to the first sole, the sole plate including a forefoot portion and a heel portion. The forefoot portion adapts to the front half of the human foot, and the heel portion adapts to the rear half of the human foot. The first sole is made of a flexible and lightweight material to reduce the impact of the ground on the foot during walking, thereby improving the consumer's experience. The second sole is made of a wear-resistant material to reduce wear on the second sole during walking, thereby increasing the service life of the second sole.

[0006] Both the forefoot and heel sections are provided with staggered first and second anti-slip protrusions. The first anti-slip protrusions are radially arranged and include uniformly distributed first anti-slip portions, with their inward-facing ends connected to each other. The cross-section of the second anti-slip protrusion is triangular or triangular-like. The staggered arrangement of the first and second anti-slip protrusions provides friction in different directions and angles, improving the friction of the first sole. Simultaneously, the radial first anti-slip protrusions more effectively disperse forces from all directions, preventing slippage due to excessive local pressure; the triangular or triangular second anti-slip protrusions allow the edge portions to more effectively embed into minute uneven surfaces, thereby significantly increasing friction.

[0007] Specifically, a triangle-like shape is defined as a triangle in which at least one of its three sides is rounded and / or the connection between the three sides is rounded.

[0008] The first anti-slip protrusion located on the forefoot is inclined towards the middle of the second sole, and the first anti-slip protrusion located on the heel is also inclined towards the middle of the second sole. The inclined first anti-slip protrusion can distribute the pressure more evenly across the entire first anti-slip protrusion when in contact with the ground, preventing excessive force at a single point from causing slippage, and further improving the anti-slip effect of the first anti-slip protrusion.

[0009] Multiple meandering drainage channels are formed between the first anti-slip protrusion and the second anti-slip protrusion. When the shoes step on puddles, they are used to guide the water from the bottom of the shoes out, reducing the splashing effect when the shoes step on puddles.

[0010] Specifically, the second anti-slip protrusion gradually decreases in size from the sole plate outwards, forming a frustum shape. This makes the contact area between the second anti-slip protrusion and the ground smaller than the contact area with the sole plate. While ensuring the anti-slip effect of the second anti-slip protrusion, it also takes into account the connection strength between the anti-slip protrusion and the sole plate, further improving the reliability of the second anti-slip protrusion.

[0011] Preferably, the sole plate is further provided with a plurality of third anti-slip protrusions. The third anti-slip protrusions are located on both sides of the sole plate and extend along the contour of the sole plate, so that the sole can obtain stronger support when the consumer moves laterally or turns, preventing the sole plate from being partially suspended, reducing the risk of the consumer falling when moving laterally or turning, and further improving the reliability of the shoe.

[0012] Specifically, a second drainage groove is formed between the third anti-slip protrusions, which is connected to the outside. The first drainage groove is connected to the second drainage groove, so that when the sole comes into contact with water, the water can be quickly guided to the edge of the sole and drained, reducing the time that water stays on the sole, thereby reducing the risk of slipping due to water accumulation and improving the safety of the shoes.

[0013] Specifically, the front and rear ends of the sole are provided with multiple fourth and fifth anti-slip protrusions. The fourth anti-slip protrusions are symmetrically arranged on both sides of the second anti-slip protrusion, forming a third drainage groove between them. One end of the third drainage groove is connected to the first drainage groove, and the other end is connected to the outside. Since the toes are usually the last to leave the ground when walking, and the heels are usually the first to touch the ground, the toes and heels experience the greatest force and are most prone to slipping at this time. The fourth and fifth anti-slip protrusions are used to increase the friction between the toe and heel and the ground, respectively, preventing slippage when the toes leave the ground and the heels land, thus improving the anti-slip effect of the shoe's toe and heel during walking.

[0014] Specifically, the fourth anti-slip protrusion has a rectangular cross-section, and the fifth anti-slip protrusion has a V-shaped cross-section, with both protrusions gradually decreasing in size outwards from the sole. Compared to circular or other shapes, the rectangular cross-section provides a larger contact area within the same radial dimension, improving the anti-slip effect of the fourth anti-slip protrusion. The V-shaped cross-section prevents lateral slippage at the toe and heel during side movement or turning, further enhancing the anti-slip performance of both the fourth and fifth anti-slip protrusions.

[0015] Preferably, the angle between the side of the first anti-slip protrusion and the vertical plane of the sole plate is α, and the range of α is 0°-30°. Since the first anti-slip protrusion occupies more area on the sole plate when tilted, when α is in the range of 0°-30°, it can improve the anti-slip effect while avoiding a single first anti-slip protrusion occupying too much area on the sole plate, which would reduce the number of first anti-slip protrusions and thus reduce the anti-slip effect.

[0016] Preferably, the first anti-slip protrusion is further provided with an anti-slip groove, which corresponds to the first anti-slip part. The anti-slip groove further improves the surface roughness of the first anti-slip protrusion, thereby increasing the coefficient of friction of the first anti-slip protrusion and further increasing the friction between the first anti-slip protrusion and the ground.

[0017] Preferably, the second sole is also provided with an information section, which displays information such as the brand and / or size of the shoe, so that consumers can quickly understand the relevant information of the shoe, make it easier for consumers to choose the right shoe for themselves, and improve the consumer's shopping experience.

[0018] Preferably, the periphery of the second sole and the bottom surface form a rounded transition. Traditional soles have a right-angle transition between the periphery and the bottom surface, which can easily lead to ankle sprains when the shoe edge hits an obstacle. The rounded transition between the periphery and the bottom surface of the second sole provides space to avoid obstacles at the shoe edge. When the shoe edge hits an obstacle, it reduces the reaction force of the obstacle on the shoe, thereby reducing the risk of ankle sprains and improving shoe safety.

[0019] The beneficial effects of this utility model are:

[0020] This invention proposes a shoe sole mechanism to increase friction. Through staggered first and second anti-slip protrusions, friction is provided in different directions and angles, thus improving the friction of the first shoe sole. Simultaneously, the radially arranged first anti-slip protrusions more effectively disperse forces from all directions, preventing slippage caused by excessive local pressure; the triangular or near-triangular second anti-slip protrusions allow the edges to more effectively embed into minute uneven surfaces, thereby significantly increasing friction.

[0027] 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 a part of the embodiments of the present utility model, and not all of them. 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.

[0028] like Figures 1-4 As shown, a shoe sole structure for increasing friction is provided at the bottom of a shoe, including a first sole 2 and a second sole 1 disposed vertically. The first sole 2 is connected to the shoe body, and the second sole 1 is in contact with the ground. A shoe cavity for accommodating a human foot is formed between the first sole 2 and the shoe body. The second sole 1 includes a sole plate 11 adapted to the first sole 2. The sole plate 11 includes a forefoot portion 111 and a heel portion 112. The forefoot portion 111 is adapted to the front half of the human foot, and the heel portion 112 is adapted to the rear half of the human foot. The first sole 2 is made of a flexible and lightweight material to reduce the impact of the ground on the human foot during walking, thereby improving the consumer's experience. The second sole 1 is made of abrasion-resistant material to reduce wear on the second sole 1 during walking, thereby increasing the service life of the second sole 1.

[0029] In this embodiment, the second sole 1 is also provided with an information section 12, which displays information such as the brand and / or size of the shoe, so that consumers can quickly understand the relevant information of the shoe, make it easier for consumers to choose the right shoe for themselves, and improve the consumer experience.

[0030] In this embodiment, the periphery of the second sole 1 transitions to the bottom surface with a rounded arc. Traditional soles have a right-angle transition between the periphery and the bottom surface, which can easily lead to ankle sprains when the shoe edge hits an obstacle. The rounded arc transition between the periphery and the bottom surface of the second sole 1 provides space at the shoe edge to avoid obstacles. When the shoe edge hits an obstacle, the reaction force from the obstacle is reduced, thereby lowering the risk of ankle sprains and improving shoe safety.

[0031] Both the forefoot portion 111 and the heel portion 112 are provided with staggered first anti-slip protrusions 113 and second anti-slip protrusions 114. The first anti-slip protrusions 113 are radial and include uniformly arranged first anti-slip portions 1131. The inward ends of the first anti-slip portions 1131 are connected to each other.

[0032] In this embodiment, the first anti-slip protrusion 113 is further provided with an anti-slip groove 1132, which corresponds to the first anti-slip part 1131. The anti-slip groove 1132 further improves the surface roughness of the first anti-slip protrusion 113, thereby increasing the coefficient of friction of the first anti-slip protrusion 113 and further increasing the friction between the first anti-slip protrusion 113 and the ground.

[0033] The first anti-slip protrusion 113 located on the forefoot portion 111 is inclined towards the center of the second sole 1, and the first anti-slip protrusion 113 located on the heel portion 112 is also inclined towards the center of the second sole 1. The inclined first anti-slip protrusion 113 can distribute the pressure more evenly across the entire first anti-slip protrusion 113 when in contact with the ground, preventing excessive force at a single point from causing slippage, and further improving the anti-slip effect of the first anti-slip protrusion 113.

[0034] In this embodiment, the angle α between the side of the first anti-slip protrusion 113 and the vertical plane of the sole plate 11 is 20°. Since the first anti-slip protrusion 113 occupies more area on the sole plate 11 when tilted, when α is 20°, it can improve the anti-slip effect while avoiding a single first anti-slip protrusion 113 occupying too much area on the sole plate 11, which would reduce the number of first anti-slip protrusions 113 and thus reduce the anti-slip effect.

[0035] The second anti-slip protrusion 114 has a triangular or triangular cross-section. The staggered arrangement of the first and second anti-slip protrusions 113 and 114 provides friction in different directions and angles, increasing the friction of the first sole 2. Simultaneously, the radially arranged first anti-slip protrusions 113 more effectively disperse forces from all directions, preventing slippage due to excessive local pressure; the triangular or triangular second anti-slip protrusions 114 allow their edges to more effectively embed into minute uneven surfaces, thereby significantly increasing friction.

[0036] In this embodiment, the triangle-like shape is a triangle whose three sides are connected by a rounded transition.

[0037] Specifically, the second anti-slip protrusion 114 gradually decreases in size from the sole plate 11 outwards, forming a frustum shape. This makes the contact area between the second anti-slip protrusion 114 and the ground smaller than the contact area with the sole plate 11. While ensuring the anti-slip effect of the second anti-slip protrusion 114, it also takes into account the connection strength between the anti-slip protrusion and the sole plate 11, further improving the reliability of the second anti-slip protrusion 114.

[0038] In this embodiment, the sole plate 11 is also provided with a plurality of third anti-slip protrusions 115. The third anti-slip protrusions 115 are provided on both sides of the sole plate 11 and extend along the contour of the sole plate 11, so that the sole can obtain stronger support when the consumer moves laterally or turns, preventing the sole plate 11 from being partially suspended, reducing the risk of the consumer falling when moving laterally or turning, and further improving the reliability of the shoe.

[0039] Multiple meandering drainage grooves 116 are formed between the first anti-slip protrusion 113 and the second anti-slip protrusion 114. When the shoes step on the water, they are used to guide the water from the bottom of the shoes out, reducing the splashing effect when the shoes step on the water.

[0040] Specifically, a second drainage groove 117 is formed between the third anti-slip protrusions 115, which communicates with the outside. The first drainage groove 116 is connected to the second drainage groove 117, so that when the sole comes into contact with water, the water can be quickly guided to the edge of the sole and drained, reducing the time that water stays on the sole, thereby reducing the risk of slipping due to water accumulation and improving the safety of the shoes.

[0041] Specifically, the front and rear ends of the sole plate 11 are provided with multiple fourth anti-slip protrusions 118 and fifth anti-slip protrusions 119. The fourth anti-slip protrusions 118 are symmetrically arranged on both sides of the second anti-slip protrusion 114, forming a third drainage groove 120 between them and the fifth anti-slip protrusions 119. One end of the third drainage groove 120 is connected to the first drainage groove 116, and the other end is connected to the outside. Since the toes are usually the last to leave the ground when walking, and the heels are usually the first to touch the ground, the toes and heels are under the greatest force and are most prone to slipping at this time. The fourth anti-slip protrusions 118 and fifth anti-slip protrusions 119 are used to increase the friction between the toe and heel and the ground, respectively, to prevent slipping when the toes leave the ground and the heels land, thus improving the anti-slip effect of the toe and heel when walking.

[0042] Specifically, the fourth anti-slip protrusion 118 has a rectangular cross-section, and the fifth anti-slip protrusion 119 has a V-shaped cross-section. Both the fourth and fifth anti-slip protrusions 118 and 119 gradually decrease in size outwards from the sole plate 11. Compared to circular or other shapes, the rectangular cross-section provides a larger contact area within the same radial dimension, improving the anti-slip effect of the fourth anti-slip protrusion 118. The V-shaped cross-section prevents lateral slippage of the toe and heel during side movement or turning, further enhancing the anti-slip effect of the fourth and fifth anti-slip protrusions 118 and 119.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
