Description

Technical Field

[0001] The present application relates to the technical field of shoes, and in particular to a high-resilience sole. Background Art

[0002] In the prior art, high-rebound materials such as EVA and polyurethane are often used to make soles, so that the soles have high resilience performance.

[0003] However, while the sole has high resilience, it also has a large deformation capacity; as a result, the support direction of the sole for the wearer's foot may be tilted, causing the wearer's foot to flip outward or inward, resulting in a sprained foot. Utility Model Content

[0004] In order to increase the stability of the high-rebound sole in supporting the wearer's foot, the present application provides a high-rebound sole.

[0005] The present application provides a high-resilience sole, which adopts the following technical solution:

[0006] A high-rebound sole comprises a sole body, wherein the sole body comprises a first rebound area and a second rebound area, wherein the second rebound area is arranged around the periphery of the first rebound area, the first rebound area is provided with a plurality of first rebound columns, and the second rebound area is provided with a plurality of second rebound columns; the rebound performance of the first rebound area is higher than the rebound performance of the second rebound area, and the first rebound column contacts the ground before the second rebound column.

[0007] By adopting the above technical solution, when the wearer's foot lands on the ground, the first rebound column in the first rebound zone interacts with the ground, so that the first rebound column is compressed and deformed to relieve the impact force of the ground on the wearer's foot and improve the wearer's comfort. Subsequently, the second rebound column in the second rebound zone contacts the ground; because the rebound energy of the second rebound column is less than the rebound energy of the second rebound column, the compression deformation of the second rebound column is small, so that the second rebound column has a good support effect on the wearer's foot. At the same time, the second rebound column is arranged around the first rebound column, so that a plurality of rebound columns form a larger support surface, so as to further improve the support effect of the second rebound column on the wearer's foot.

[0008] That is, through the coordinated cooperation of the first rebound zone and the second rebound zone, the first rebound zone makes the sole body have good rebound performance, and the second rebound zone makes the sole body have good supporting effect on the wearer's foot; thus, the sole has both high rebound and good supporting effect, reducing the risk of sprains of the wearer's foot.

[0009] Optionally, the first rebound column includes a first rebound column at the sole and a first rebound column at the heel; the first rebound column at the sole is laid on the sole portion of the sole, and the first rebound column at the heel is laid on the heel portion of the sole; the height of the first rebound column at the heel is greater than the height of the first rebound column at the sole.

[0010] By adopting the above technical solution, when the wearer's foot lands on the ground, the heel of the sole will generate a greater impact force with the ground; and the first rebound column of the heel located at the heel has a greater height, so that the second rebound column can play a good buffering and shock absorbing effect.

[0011] Optionally, the volume of the first rebound columns at the sole of the foot is smaller than that of the first rebound columns at the heel, and the laying density of the first rebound columns at the sole of the foot is greater than that of the first rebound columns at the heel.

[0012] By adopting the above technical solution, the first rebound columns with a larger density can increase the stable rebound force for the wearer's feet, so as to assist the wearer's feet to leave the ground.

[0013] Optionally, the first rebound column is provided with an anti-skid textured surface, and the anti-skid textured surface is used to abut against the ground.

[0014] By adopting the above technical solution, when the first rebound column interacts with the ground, the friction between the first rebound column and the ground can be increased, so as to give full play to the resilience performance of the first rebound column.

[0015] Optionally, it further includes a non-slip rubber portion, and the non-slip rubber portion is fixedly connected to the second rebound column.

[0016] By adopting the above technical solution, the anti-skid rubber part has good wear-resistant and anti-skid performance, so as to provide friction between the ground and the sole, thereby reducing the slipping between the sole and the ground.

[0017] Optionally, the sole body further includes a rebound component, and the rebound component is embedded in the first rebound column of the heel.

[0018] By adopting the above technical solution, when a large force is exerted between the first rebound column and the ground, the rebound component will also be compressed and deformed; thereby, the rebound performance of the first rebound column of the heel is further improved through the material deformation of the EVA material in the first rebound column and the structural deformation of the rebound component.

[0019] Optionally, the resilient member is a corrugated plate; the crests and troughs of the corrugated plate are arranged vertically.

[0020] By adopting the above technical solution, the structural resilience performance of the resilience member is achieved through the corrugated plate.

[0021] Optionally, the rebound member is a spiral tube, and the hardness of the spiral tube is greater than the hardness of the first rebound column of the heel.

[0022] By adopting the above technical solution, the structural resilience performance of the resilience piece is achieved through the spiral tube.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the coordinated cooperation of the first rebound area and the second rebound area, the first rebound area enables the sole body to have good rebound performance, and the second rebound area enables the sole body to have a good supporting effect on the wearer's foot; thus, the sole has both high rebound and good supporting effects, reducing the risk of sprains on the wearer's foot;

[0025] 2. When the wearer's foot lands on the ground, the heel of the sole will generate a large impact force with the ground; and the first rebound column of the heel located at the heel has a large height, so that the second rebound column can play a good cushioning and shock absorbing effect;

[0026] 3. When a large force is exerted on the first rebound column and the ground, the rebound component will also be compressed and deformed; thereby, the rebound performance of the first rebound column at the heel is further improved through the material deformation of the EVA material in the first rebound column and the structural deformation of the rebound component.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a high-resilience sole. Figure 1 Along the direction from the toe of the high-rebound sole to the tail of the shoe, the high-rebound sole includes a toe portion 11, a sole portion 12, an arch portion 13, a heel portion 14 and a tail portion 15 in sequence.

[0035] Reference Figure 1 In this embodiment, the high-rebound sole includes a sole body 1, and the sole body 1 includes a first rebound area 2 and a second rebound area 3. The second rebound area 3 is arranged around the periphery of the first rebound area 2, and the first rebound area 2 is provided with a plurality of first rebound columns 21, and the second rebound area 3 is provided with a plurality of second rebound columns 31. The rebound performance of the first rebound area 2 is higher than that of the second rebound area 3, and the first rebound column 21 contacts the ground before the second rebound column 31.

[0036] In this embodiment, the sole body 1 is made of EVA material by foaming; in other embodiments, the sole body 1 can also be made of polyurethane material. The resilience of EVA material is related to the molecular weight, vinyl acetate (VA) content, and foaming method of the material; the larger the molecular weight of the EVA material, the higher the vinyl acetate (VA) content, and the higher the elasticity of the EVA foaming material; the content of chemical foaming agent (such as azodicarbonamide) and cross-linking agent (such as diisopropylbenzene peroxide) used in the foaming process of the EVA material also has a great influence on the resilience of the EVA material after foaming.

[0037] Therefore, the first rebound zone 2 and the second rebound zone 3 may use different EVA materials, or use different foaming methods to foam the EVA materials, so that the rebound performance of the first rebound zone 2 is greater than the rebound performance of the second rebound zone 3. In this embodiment, the present application achieves the difference in rebound performance between the first rebound zone 2 and the second rebound zone 3 by controlling the vinyl acetate (VA) content of the first rebound zone 2 and the second rebound zone 3; in other embodiments, the staff may also use other methods to achieve the difference in rebound performance between the first rebound zone 2 and the second rebound zone 3.

[0038] Reference Figure 1 and Figure 2When the wearer's foot lands on the ground, the first rebound column 21 of the first rebound zone 2 interacts with the ground, causing the first rebound column 21 to be compressed and deformed to relieve the impact of the ground on the wearer's foot and improve the wearer's comfort. Subsequently, the second rebound column 31 of the second rebound zone 3 contacts the ground; since the rebound performance of the second rebound column 31 is less than the rebound performance of the second rebound column 31, the compression deformation of the second rebound column 31 is small, so that the second rebound column 31 has a good support effect on the wearer's foot. At the same time, the second rebound column 31 is arranged around the first rebound column 21, so that a plurality of rebound columns form a larger support surface, so as to further improve the support effect of the second rebound column 31 on the wearer's foot.

[0039] That is, through the coordinated cooperation of the first rebound area 2 and the second rebound area 3, the first rebound area 2 makes the sole body 1 have good rebound performance, and the second rebound area 3 makes the sole body 1 have a good supporting effect on the wearer's foot; thereby, the sole has both high rebound and good supporting effects, reducing the risk of sprains of the wearer's foot.

[0040] Reference Figure 1 Meanwhile, the first resilience column 21 includes a sole first resilience column 211 and a heel first resilience column 212; the sole first resilience column 211 is laid on the sole portion 12 of the sole, and the heel first resilience column 212 is laid on the heel portion 14 of the sole; the height of the heel first resilience column 212 is greater than the height of the sole first resilience column 211. When the wearer's foot lands on the ground, the heel portion 14 of the sole will generate a large impact force with the ground; and the heel first resilience column 212 located at the heel portion 14 has a large height, so that the second resilience column 31 can play a good buffering and shock absorbing effect.

[0041] Reference Figure 1 In this embodiment, the volume of the first resilience columns 211 at the sole is smaller than that of the first resilience columns 212 at the heel, and the laying density of the first resilience columns 211 at the sole is greater than that of the first resilience columns 212 at the heel. When the wearer starts to move, the sole 12 of the wearer and the ground have a greater relative force, and the first resilience columns 21 with a greater density can increase the stable rebound force for the wearer's foot to help the wearer's foot leave the ground.

[0042] Example 2

[0043] The difference between this embodiment 2 and embodiment 1 is that:

[0044] Reference Figure 3The high-rebound sole further includes an anti-skid rubber part 4, which is fixedly connected to the second rebound column 31. The anti-skid rubber part 4 is made of rubber and has good wear-resistant and anti-skid properties. Therefore, when the second rebound column 31 interacts with the ground, the anti-skid rubber part 4 at the bottom of the second rebound column 31 rubs against the ground; since the anti-skid rubber part 4 has good wear-resistant and anti-skid properties, it can provide friction between the ground and the sole, thereby reducing the slipping of the sole and the ground.

[0045] Meanwhile, the first resilient column 21 is provided with an anti-skid textured surface 213, which is used to abut against the ground, so that when the first resilient column 21 interacts with the ground, the friction between the first resilient column 21 and the ground can be increased to give full play to the resilience of the first resilient column 21.

[0046] Example 3

[0047] The difference between this embodiment 3 and embodiment 1 is that:

[0048] Reference Figure 4 The sole body 1 also includes a resilient member, which is embedded in the first resilient column 212 of the heel. In this embodiment, the resilient member is a corrugated plate 5, and the crests and troughs of the corrugated plate 5 are arranged vertically. Therefore, when a large force is exerted on the first resilient column 212 of the heel and the ground, the first resilient column 212 of the heel is compressed and deformed, and the corrugated steel plate is forced to undergo structural deformation; thereby, the material deformation of the EVA material in the first resilient column 212 of the heel and the structural deformation of the corrugated plate 5 further improve the resilience of the first resilient column 212 of the heel. The corrugated plate 5 can be a corrugated thin steel plate; in other embodiments, the corrugated plate 5 can also be a thin plate with a certain rigidity.

[0049] Example 4

[0050] The difference between this embodiment 4 and embodiment 1 is that:

[0051] Reference Figure 5, the rebound member is a spiral tube 6, and the hardness of the spiral tube 6 is greater than the hardness of the first rebound column 212 of the heel. In this embodiment, the spacing of the coils in the spiral tube 6 increases from the middle to both sides, so as to facilitate the deformation of the spiral tube 6. Therefore, when the first rebound column 21 and the ground have a large force, the first rebound column 212 of the heel is compressed and deformed, and the spiral tube 6 is forced to undergo structural deformation; thereby, the material deformation of the EVA material in the first rebound column 212 of the heel and the structural deformation of the spiral tube 6 further improve the resilience of the first rebound column 212 of the heel. The spiral tube 6 can be made of EVA material with a relatively large hardness; when the staff foams the EVA sole body 1 in the mold, the staff can set the already foamed spiral tube 6 in the mold so that the spiral tube 6 is buried in the first rebound column 212 of the heel. In other embodiments, the spiral tube 6 can also be made of a material with a certain hardness, such as a plastic material or a metal material.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
