Description

Technical Field

[0001] This invention relates to the field of shoe sole drainage structure technology, specifically to a shoe sole and a shoe. Background Technology

[0002] Shoe soles typically consist of an outsole and a midsole, sometimes including other components such as TPU. The outsole is the layer that directly contacts the ground and is usually made of natural or synthetic rubber, providing slip resistance and abrasion resistance. The side of the outsole facing the ground usually has regular or irregular patterns, which increase friction and improve slip resistance. However, when there is water on the ground, a water film will form between the outsole and the ground after contact, which will reduce the outsole's slip resistance. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sole and a shoe that can prevent the formation of a water film between the sole and the ground when stepping on a wet surface, thereby effectively improving the anti-slip performance of the sole.

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

[0005] A shoe sole has a forefoot region and an outer edge and an inner edge. The shoe sole has a plurality of first grooves and second grooves arranged and intersecting each other in its length direction. The first grooves extend from a first position on the inner edge to a second position on the outer edge, the first position being closer to the rear end of the shoe sole than the second position. The second grooves extend from a third position on the inner edge to a fourth position on the outer edge, the third position being closer to the front end of the shoe sole than the fourth position. At least a portion of the first grooves located in the forefoot region bends toward the front end of the shoe sole; at least a portion of the second grooves located on the front side of the forefoot region bends toward the rear end of the shoe sole, and at least a portion of the second grooves located on the rear side of the forefoot region bends toward the front end of the shoe sole.

[0006] Furthermore, the sole surface is provided with a plurality of protruding particle units; the plurality of particle units are arranged sequentially from the inner edge to the outer edge to form a first unit module, and are arranged sequentially from the front end of the sole towards the rear end of the sole to form a second unit module; the first unit module is arranged along the length of the sole, and is divided into a first row group and a second row group along the extension direction; the first row group extends from the fifth position of the inner edge to the sixth position of the outer edge, the fifth position being closer to the rear end of the sole than the sixth position; the second row group extends from the seventh position of the inner edge to the eighth position of the outer edge, the seventh position being closer to the rear end of the sole than the sixth position. Compared to the eighth position, it is closer to the front end of the sole; adjacent first row groups form the first grooves arranged in the length direction of the sole; adjacent second row groups form the second grooves arranged in the length direction of the sole; each particle unit is simultaneously located in a first row group and a second row group, and the front end of the particle unit points to the groove intersection, the groove intersection is formed by the first groove and second groove formed by the first row group and second row group corresponding to the particle unit and another first row group and second row group located in front of it; the second unit module is arranged along the width direction of the sole and is located in the forefoot area.

[0007] Furthermore, the second unit module extends in close proximity to the curved structure of the inner edge and gradually straightens as it moves away from the inner edge.

[0008] Furthermore, the particle unit is located between two adjacent particle units of the second unit module adjacent to it in the length direction of the sole.

[0009] Furthermore, the particle unit extends into the range of the adjacent second unit module on both sides of the sole width direction.

[0010] Furthermore, the rear end of the particle unit is recessed towards the front end of the shoe sole to form a water-retaining section.

[0011] Furthermore, the sole has water-retaining holes at at least a portion of the water-retaining portion of the particle units; the water-retaining holes are recessed relative to the bottom surface of the sole or penetrate the sole.

[0012] Furthermore, the size of the particle unit increases and then decreases in the forefoot region from the front end of the sole to the rear end of the sole; the size of the particle unit increases and then decreases in the forefoot region from the inner edge to the outer edge.

[0013] Furthermore, the sole also has an arch area and a heel area; the particle units are also distributed in the arch area and the heel area, and cooperate to form the first groove and the second groove.

[0014] In addition, the present invention also provides a shoe comprising an outsole formed of any of the above-described solesoles, a midsole bonded to the outsole, and an upper bonded to the midsole.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By incorporating a first and second groove on the sole, when the sole comes into contact with water on the ground, the water is forced into the grooves and then drained away along them. This prevents the formation of a water film between the sole and the ground, or reduces the thickness of any water film, thereby increasing the friction between the sole and the ground and preventing the sole from slipping relative to the ground, thus enhancing the sole's anti-slip performance. Simultaneously, the grooves are designed with a curved shape, so that when water flows out along the grooves, it does not splash directly towards the inner and outer sides of the sole, but rather slightly towards the rear of the sole, reducing the splashing of water when the sole is stepped on onto puddles. The height and flow rate of the water jet, along with the curved shape, allow the water to stay in the groove for a longer time. The groove only needs to discharge a small amount of water in an instant to ensure that no water film is formed between the sole and the ground, or to reduce the thickness of the water film to a level that does not affect the anti-slip performance of the sole. In addition, the curved structures of the first and second grooves are different. The second groove has two parts that curve forward and backward. Both parts intersect with the first groove, but form an outward diverging shape on the inner or outer edge of the sole. This shape ensures that the water flow in each second groove does not affect each other when it is discharged, and the water flow is smoother.

[0017] 2. The first and second grooves mentioned above are formed on the sole by protruding particle units, and the front ends of these particle units point to the intersection of the grooves. When the sole is stepped on water, the particle units in the forefoot area that first come into contact with the water will squeeze the water outwards until it spreads to the entire forefoot area. During this process, the grooves with water flow will drain water to the surrounding grooves. When the water flows through the surrounding grooves, it will collide with the front ends of these particle units and be branched into the two grooves on the inner and outer sides of the sole, thereby quickly dispersing the water flow. The amount of water in a certain position will be greatly reduced, and the water flow can be quickly discharged.

[0018] 3. The shape change of the second unit module affects the size and position of the particle unit. The particle unit extending close to the inner edge of the sole can provide better grip for the sole, and the more suitable size can also make it squeeze out water more quickly.

[0019] 4. Each particle unit forms a cross-arranged structure with the particle units on both sides. This structure allows the first and second grooves to be set on the sole at an angle, while also increasing the speed at which water is dispersed on the sole, so that the water can be drained away quickly.

[0020] 5. Each particle unit extends into the range of the second unit module on both sides, thus preventing the sole from forming a continuous groove structure in the front-to-back direction. Water can only flow in the first and second grooves and be discharged to the sides of the sole, but cannot flow in the front-to-back direction. This is because the front-to-back dimension of the sole is larger than its inner and outer dimensions. If water flows in the front-to-back direction of the sole, it will cause the water to remain on the sole for a long time, which is not conducive to the drainage of water after the sole is stepped on again and the ground is flooded.

[0021] 6. A forward-recessed water-retaining part is formed on the particle unit. After the sole of the shoe comes into contact with water on the ground, some of the water can be squeezed into the water-retaining part. At the same time, the top of the particle unit will directly contact the ground. The existence of the water-retaining part means that the water does not have to be completely drained from the sole, reducing the drainage pressure of the sole. At the same time, it can also prevent the formation of a water film between the sole and the ground. The particle unit can provide a good anti-slip effect for the sole.

[0022] 7. Water-retaining holes are also provided on the sole of the shoe, which can further improve the water-retaining capacity of the sole.

[0023] 8. When the sole is stepped on the ground, the middle part of the forefoot area will bear a greater force, resulting in a greater degree of deformation in this area. Therefore, the particle unit size in this area is set to be larger, so that the particle unit in this area can more efficiently squeeze the water flow into the groove.

[0024] 9. The particle units are also distributed in the arch area and heel area. These particle units can work together to form the first groove and the second groove, so that the arch area and heel area of ​​the sole can also have a good anti-slip effect.

[0025] 10. The present invention also provides a shoe that uses the above-mentioned sole, thus having good anti-slip performance. Attached Figure Description

[0040] Example 1

[0041] See Figures 1 to 4 , Figure 1 A schematic diagram of an embodiment of a shoe sole 10 provided by the present invention is shown. The shoe sole 10 has a forefoot region 101, an arch region 102, and a heel region 103 from its front end to its rear end. These regions correspond to the forefoot, arch, and heel of the human foot, respectively. Although there are no obvious dividing lines between these regions, those skilled in the art can easily determine their approximate locations based on common knowledge in the field, and can make corresponding improvements to these regions according to actual needs based on the technical solution provided by the present invention. In addition, the shoe sole 10 also has an inner edge 104 and an outer edge 105, which are provided corresponding to the inner and outer sides of the human foot. The inner side refers to the side facing the other foot, and the outer side refers to the side facing outwards from the human body. In the shoe sole 10 of the left and right feet, these edges are opposite, but this does not affect the definition of these edges.

[0042] In addition, it should be noted that the inner edge 104 and outer edge 105 of the sole 10 do not extend along a straight line, but rather conform to the shape of the human foot with a constantly changing curvature structure. This curved shape allows the sole 10 to provide better support for the human foot without increasing the weight of the sole 10 excessively, and also makes the appearance more aesthetically pleasing.

[0043] Furthermore, the "length direction" referred to in this specification refers to the direction from the front end to the rear end of the sole 10. It is not expressed as a straight line, but changes with the extension direction of the sole 10. However, it can be generally considered that the length direction points from the front end to the rear end of the sole 10. Similarly, the "width direction" referred to in this specification refers to the direction from the inner edge 104 to the outer edge 105 of the sole 10. However, it is also not expressed as a straight line, but changes with the shape of the sole 10 in width. However, it can be generally considered that the length direction points from a position on the inner edge 104 of the sole 10 along a straight line to a corresponding position on the outer edge 105 of the sole 10.

[0044] See Figure 1 In this embodiment, the sole 10 is provided with a plurality of first grooves 21 and second grooves 22 arranged and intersecting each other in its length direction. The first grooves 21 extend from a first position of the inner edge 104 to a second position of the outer edge 105, and the second grooves 22 extend from a third position of the inner edge 104 to a fourth position of the outer edge 105. The first position is closer to the rear end of the sole 10 than the second position, and the third position is closer to the front end of the sole 10 than the fourth position.

[0045] Specifically, the first groove 21 extends obliquely from the inner edge 104 toward the front end of the sole 10 to the outer edge 105, and the second groove 22 extends obliquely from the outer edge 105 toward the front end of the sole 10 to the inner edge 104. The first groove 21 is arranged along the length of the sole 10 from the forefoot area 101 to the heel area 103, and the second groove 22 is also arranged along the length of the sole 10 from the forefoot area 101 to the heel area 103. Therefore, the first groove 21 and the second groove 22 can form an interlocking structure, and multiple groove intersections 23 are formed in the extension direction of each first groove 21 or second groove 22. These groove intersections 23 can disperse water flow into the first groove 21 and the second groove 22 that are connected to them.

[0046] Through the first groove 21 and the second groove 22 extending to the inner edge 104 and the outer edge 105 of the sole 10, water can be quickly drained away from these grooves, thereby preventing the formation of a water film between the sole 10 and the ground, or greatly reducing the thickness of the water film, thereby increasing the friction between the sole 10 and the ground and ensuring that the sole 10 has sufficient anti-slip effect.

[0047] Furthermore, on the sole 10, at least part of the first groove 21 located in the forefoot region 101 bends toward the front end of the sole 10; at least part of the second groove 22 located in the front of the forefoot region 101 bends toward the rear end of the sole 10, and at least part of the second groove 22 located in the rear of the forefoot region 101 bends toward the front end of the sole 10.

[0048] Specifically, the bending direction of the first groove 21 is roughly the same in the forefoot region 101, only the degree of bending differs. Figure 1 Taking the sole 10 shown as an example, the first groove 21 has a smaller degree of curvature on the rear side of the forefoot region 101, a larger degree of curvature on the middle side of the forefoot region 101, and a smaller degree of curvature on the front side of the forefoot region 101, forming a shape with the largest degree of curvature in the middle position. This shape can help the parts of the forefoot region 101 of the sole 10 that are under greater force to drain water more efficiently.

[0049] Similarly, the bending direction of the second groove 22 is also different in the forefoot area 101. Unlike the first groove 21, the second groove 22 bends towards the front end of the sole 10 on the rear side of the forefoot area 101, and towards the rear end of the sole 10 on the front side of the forefoot area 101. Therefore, the opening of the second groove 22 at the outer edge 105 of the sole 10 is constricted, while the opening at the inner edge 104 of the sole 10 is divergent. This shape allows water flow to be discharged from the second groove 22 without affecting each other.

[0050] It should be noted that the first position, second position, third position and fourth position mentioned above are all in relation to a first groove 21 or a second groove 22. The positions corresponding to each groove are not the same, but in the same groove, the two opposite positions indicate the inclination direction of the groove.

[0051] It should be understood that during the molding process, the first groove 21 and the second groove 22 will correspondingly protrude on the ground of the sole 10 to form multiple particle units 11.

[0052] In this arrangement, multiple particle units 11 are sequentially arranged from the inner edge 104 of the sole 10 to the outer edge 105 of the sole 10 to form a first unit module, and sequentially arranged from the front end of the sole 10 toward the rear end of the sole 10 to form a second unit module. The first unit module is arranged along the length of the sole 10 and is divided into a first row group and a second row group along the extension direction. The first row group extends from the fifth position of the inner edge 104 to the sixth position of the outer edge 105, with the fifth position being closer to the rear end of the sole 10 than the sixth position. The second row group extends from the seventh position of the inner edge 104 to the eighth position of the outer edge 105, with the seventh position being closer to the front end of the sole 10 than the eighth position. Adjacent first row groups form first grooves 21 arranged along the length of the sole 10, and adjacent second row groups form second grooves 22 arranged along the length of the sole 10. Each particle unit 11 is simultaneously located in a first row group and a second row group.

[0053] Specifically, the first unit module and the second unit module are simply divisions based on the arrangement of the particle units 11 on the sole 10 from different angles. Similarly, the first row group and the second row group in the first unit module are also divided based on the arrangement of the particle units 11 from different angles. Both the first unit module and the second unit module are composed of particle units 11. The above division is only for the convenience of explaining and limiting the arrangement of the particle units 11 and does not constitute a limitation on its protection scope.

[0054] The first unit module refers to the arrangement of the particle units 11 as viewed from the width direction of the sole 10, while the second unit module refers to the arrangement of the particle units 11 as viewed from the length direction of the sole 10. In the first unit module, depending on whether the starting point is the inner edge 104 or the outer edge 105, the arrangement of the particle units 11 can be divided into a first row group and a second row group. Since the extension directions of the first row group and the second row group intersect each other, and since a first groove 21 is formed between adjacent first row groups and a second groove 22 is formed between adjacent second row groups, the first groove 21 and the second groove 22 will also form an intersecting structure, and a groove intersection 23 is formed at the intersection.

[0055] Specific reference Figure 2 Each of the aforementioned particle units 11 has a front end point 117, which points to the aforementioned groove intersection 23. More specifically, the groove intersection 23 here refers to the intersection formed by the first groove 21 and the second groove 22 formed by the first row group and the second row group corresponding to the particle unit 11 and another first row group and the second row group located in front of it.

[0056] The particle unit 11 protrudes from the base surface of the sole 10, thereby forming a side surface that extends perpendicularly to the base surface of the sole 10. The basic structure of each particle unit 11 can be regarded as a hexagon. However, in this invention, a water-retaining part 110 is recessed at the rear end of each particle unit 11 towards the front end of the sole 10. Therefore, the shape of the water-retaining part 110 will not be precisely described here, but only its side surface will be described.

[0057] Each particle unit 11 has a first side 111, a second side 112, a third side 113, a fourth side 114, a fifth side 115, and a sixth side 116, which are connected in sequence and connected to the water storage section 110 at the fourth side 114 and the fifth side 115. The second side 112 and the fifth side 115 form the main wall of the first groove 21, and the first side 111 and the fourth side 114 form the main wall of the second groove 22. The third and fourth groove walls of the particle units 11 on the left and right sides, and the rear and front ends of the upper and lower particle units 11, work together to form the groove intersection 23. The first and second groove walls are connected to the front end point 117 of the particle unit 11, and extend from the front end point 117 of the particle unit 11 towards both sides of the sole 10 and towards the rear end of the sole 10, respectively. This allows the water flow in the grooves to be divided at the front end point 117 and then diverted into the first groove 21 and the second groove 22 on both sides of the front end point 117. Taking the first groove 21 as an example, when the water flow between the second side 112 and the fifth side 115 flows from the outer edge 105 to the inner edge 104 of the sole 10, it will impact the first side 111 of the nearby particle unit 11, causing some of the water flow to flow in the second groove 22. Similarly, when the water flow flows from the inner edge 104 to the outer edge 105 of the sole 10, it will impact the third side 113 of the nearby particle unit 11, causing some of the water flow to flow in the second groove 22. The change in water flow direction in the second trench 22 is roughly the same as that in the first trench 21, and will not be described again here.

[0058] In addition, the water storage part 110 provided on the particle unit 11 temporarily stores a small amount of water when the water flows in the groove, thereby reducing the drainage pressure of the sole 10. The sole 10 does not need to drain a large amount of water in a short time, and a water film will not form between the sole 10 and the ground.

[0059] Reference Figure 3 To further improve the water retention capacity of the sole 10, a water-retaining hole 12 is also provided at the position corresponding to the water-retaining part 110 of the particle unit 11. When the sole 10 is an outsole, the water-retaining hole 12 can be a recessed sinker or a through hole that runs through the sole 10. When it is a through hole, it can also prevent water from seeping in when the sole 10 is combined with the upper midsole.

[0060] The aforementioned second unit module is arranged along the width direction of the sole 10 and located in the forefoot area 101; at the same time, the second unit module extends in a manner close to the curved structure of the inner edge 104 and gradually straightens as it moves away from the inner edge 104.

[0061] Specifically, refer to Figure 1and Figure 2 The curvature of the second module at the inner edge 104 of the sole 10 is close to that of the inner edge 104. As the second module is arranged from the inner edge 104 to the outer edge 105 of the sole 10, the curvature of the second module gradually transitions from being close to the inner edge 104 to being straight. This change in shape can provide better grip for the sole 10 at the inner edge 104 without affecting the drainage of water.

[0062] Furthermore, the particle unit 11 is located between two adjacent particle units 11 of the adjacent second unit module in the length direction of the sole 10, and the particle unit 11 extends into the range of the adjacent second unit module on both sides in the width direction of the sole 10.

[0063] This arrangement allows the particle units 11 to be arranged in an inclined direction across the second unit module. At the same time, a continuous groove structure is not formed in the length direction of the sole 10. When the water flows through the groove, it will be diverted along the side of the particle unit 11 to the corresponding first groove 21 and second groove 22. The water can only be discharged from both sides in the width direction of the sole 10.

[0064] In this embodiment, the size of the particle unit 11 increases and then decreases in the forefoot region 101 from the front end to the rear end of the sole 10, and also increases and then decreases in the forefoot region 101 from the inner edge 104 to the outer edge 105. This size variation can improve the density distribution of the particle unit 11 on the sole 10, so that the part with greater deformation when in contact with the ground can provide greater grip.

[0065] Furthermore, the aforementioned particle units 11 are also provided in the arch region 102 and heel region 103 of the sole 10, and these particle units 11 cooperate with each other to form the aforementioned first groove 21 and second groove 22 in the arch region 102 and heel region 103 of the sole 10. In the arch region 102 and heel region 103 of the sole 10, these first grooves 21 and second grooves 22 also intersect each other, so that water can be drained away from the first grooves 21 and second grooves 22.

[0066] Reference Figure 5 , Figure 5 The illustration shows the situation when the sole 10 provided by the present invention is stepped on a wet ground. In the illustration, after the sole 10 is stepped on a wet ground, the water will be drained away from the first groove 21 and the second groove 22 formed on the sole 10. The particle unit 11 on the sole 10 can directly contact the ground, thereby improving the grip of the sole 10 on the ground.

[0067] Reference Figure 6To illustrate that the sole 10 provided by the present invention has a high drainage speed, this embodiment provides a pair of proportions. The soles provided by the proportions have protrusions, but these protrusions are regularly arranged and form horizontal and vertical drainage grooves. Figure 6 The line with ID:0 represents the change in drainage speed of the sole provided in the comparative example, and the line with ID:1 represents the change in drainage speed of the sole provided in this embodiment. Figure 6 It can be seen that the sole provided in this embodiment has a higher water drainage speed than the sole provided in the comparative example after being stepped on a wet surface, and the difference is significant. This indicates that the sole provided in this embodiment can quickly drain water in the initial stage of stepping on the ground, and it has a very good drainage effect.

[0068] The present invention provides a shoe sole 10, which, by providing a first groove 21 and a second groove 22 on the shoe sole 10, causes water to be squeezed into the grooves when the shoe sole 10 comes into contact with water on the ground, and then discharged along the grooves. This prevents the formation of a water film between the shoe sole 10 and the ground, or reduces the thickness of the water film, thereby increasing the friction generated when the shoe sole 10 contacts the ground, preventing the shoe sole 10 from sliding relative to the ground, and increasing the anti-slip performance of the shoe sole 10. At the same time, the grooves are designed in a curved shape, so when the water flows out along the grooves, it will not spray directly towards the inner and outer sides of the shoe sole 10, but will be discharged slightly towards the rear end of the shoe sole 10, reducing the water spray when the shoe sole 10 is stepped on and placed on water. The splash height and flow rate of the water, along with the curved shape, allow the water to stay in the groove for a longer time. The groove only needs to discharge a small amount of water in an instant to ensure that no water film is formed between the sole 10 and the ground, or to reduce the thickness of the water film to a level that does not affect the anti-slip performance of the sole 10. In addition, the curved structures of the first groove 21 and the second groove 22 are different. The second groove 22 has two parts that curve forward and backward. Both parts intersect with the first groove 21, but form an outward diverging shape on the inner edge 104 or the outer edge 105 of the sole 10. This shape ensures that the water flow in each second groove 22 does not affect each other when it is discharged, and the water flow is smoother.

[0069] Example 2

[0070] In addition, the present invention also provides a shoe comprising an outsole formed of the sole 10 in the above embodiment 1, a midsole bonded to the outsole, and an upper bonded to the midsole.

[0071] The shoe can be of various types, such as running shoes, hiking shoes, baseball shoes, or casual shoes and other non-sports related footwear. By adopting the above-mentioned sole 10 structure, the shoe can quickly drain water when stepped on a wet surface, preventing the formation of a water film between the particle units 11 on the sole 10 and the ground, or greatly reducing the thickness of the water film. This allows the particle sole 10 to have sufficient contact area with the ground, ensuring that the sole 10 does not slip significantly with the ground. Therefore, the shoe with this sole 10 structure has good anti-slip performance.

[0072] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
