Description

Technical Field

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

[0002] In the prior art, high-rebound materials are often used to make shoe soles, so that the soles have high resilience to cushion the impact of the ground on the wearer's feet and improve the comfort of the wearer's feet.

[0003] However, relying on the rebound properties of the material to achieve high rebound performance of the sole has a slow rebound reaction speed and insufficient rebound force, which will affect the wearer's experience. Utility Model Content

[0004] In order to increase the high rebound performance of the high rebound sole and increase the rebound speed of the high rebound sole, the present application provides a high rebound sole.

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

[0006] A high-rebound sole comprises, in sequence from the toe to the heel, a toe portion, a sole portion, an arch portion, a heel portion and a heel portion; the high-rebound sole comprises an elastic midsole and a wear-resistant outsole, wherein the elastic midsole is adhesively fixed to the wear-resistant outsole; along the heel to the toe, a plurality of strip-shaped first arc-shaped protrusions are spaced apart on the heel portion of the elastic midsole, wherein the first arc-shaped protrusions are adhesively fixed to the wear-resistant outsole; the heel portion of the wear-resistant outsole contacts the ground before the heel portion.

[0007] By adopting the above technical solution, when the heel of the high-rebound sole contacts the ground, the first arc-shaped protrusion is compressed to produce structural deformation; and when the high-rebound sole separates from the ground, the heel of the high-rebound sole quickly returns to its original shape, thereby increasing the rebound speed and rebound force of the high-rebound sole and increasing the explosiveness of the rebound of the high-rebound sole.

[0008] Optionally, the elastic midsole includes a first elastic midsole and a second elastic midsole, the first elastic midsole is bonded and fixed to the wear-resistant outsole, the heel portion of the first elastic midsole is provided with the first arc-shaped protrusion, the second elastic midsole is fixed on the first elastic midsole, and the rebound performance of the second elastic midsole is higher than the rebound performance of the first elastic midsole.

[0009] By adopting the above technical solution, the second elastic midsole has greater rebound performance, making the second elastic midsole relatively soft, thereby improving the comfort of the wearer.

[0010] Optionally, a plurality of strip-shaped second arc-shaped protrusions are provided at intervals on the heel of the first elastic midsole, and the second arc-shaped protrusions are provided on the side of the first elastic midsole close to the second elastic midsole; the second elastic midsole is provided with an accommodating groove for accommodating the second arc-shaped protrusions.

[0011] By adopting the above technical solution, the connection area between the first elastic midsole and the second elastic midsole is increased, and the bonding strength between the first elastic midsole and the second elastic midsole is improved.

[0012] Optionally, the number of the first arc-shaped protrusions is the same as that of the second arc-shaped protrusions, and the first arc-shaped protrusions and the second arc-shaped protrusions are arranged opposite to each other, and the outer peripheral surfaces of the first arc-shaped protrusions and the second arc-shaped protrusions are located on the same elliptical circumference.

[0013] By adopting the above technical solution, the rebound speed and rebound force of the heel portion of the high rebound sole can be increased through the coordinated cooperation of the first arc-shaped protrusion and the second arc-shaped protrusion.

[0014] Optionally, along the length direction of the high-rebound sole, the thickness of the second elastic midsole decreases gradually toward both sides along the sole of the foot.

[0015] By adopting the above technical solution, when the wearer walks, the force between the wearer's sole and the high-rebound sole is relatively large, and the second elastic midsole is thicker at the sole, thereby providing greater rebound force for the wearer's foot.

[0016] Optionally, it also includes a corrugated steel plate, which is located at the heel of the high rebound sole. The corrugated steel plate includes a first component and a second component. The first component and the second component are integrally formed. The first component is embedded in the first elastic midsole, and the second component is embedded in the second elastic midsole.

[0017] By adopting the above technical solution, on the one hand, the corrugated steel plate can increase the connection strength between the first elastic midsole and the second elastic midsole; on the other hand, the compression deformation of the corrugated steel plate can further enhance the rebound force and rebound speed of the high rebound sole.

[0018] Optionally, the corrugated steel plate is arranged vertically.

[0019] By adopting the above technical solution, the corrugated steel plate is arranged vertically, which is beneficial to the deformation of the corrugated steel plate.

[0020] Optionally, the corrugated steel plate is arranged between two adjacent second arc-shaped protrusions.

[0021] By adopting the above technical solution, the corrugated steel plate and the second arc-shaped protrusion cooperate with each other, further enhancing the rebound performance of the high-rebound sole.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the heel of the high-rebound sole contacts the ground, the first arc-shaped protrusion is compressed and deforms the structure; when the high-rebound sole separates from the ground, the heel of the high-rebound sole quickly returns to its original shape, thereby increasing the rebound speed and rebound force of the high-rebound sole and enhancing the explosiveness of the rebound of the high-rebound sole;

[0024] 2. The first arc-shaped protrusion and the second arc-shaped protrusion cooperate with each other to increase the rebound speed and rebound force of the heel of the high-rebound sole;

[0025] 3. When the wearer walks, the force between the wearer's sole and the high-rebound sole is relatively large, and the second elastic midsole is thicker at the sole, thereby providing greater rebound force for the wearer's foot. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application discloses a high-rebound sole. Figure 1 , along the direction from the toe to the tail, the high rebound sole includes the toe portion, the sole portion, the arch portion, the heel portion and the tail portion in sequence.

[0033] Reference Figure 1 and Figure 2The high-rebound sole includes an elastic midsole 1 and a wear-resistant outsole 2. The elastic midsole 1 is adhesively fixed to the wear-resistant outsole 2. In this embodiment, the elastic midsole 1 includes a first elastic midsole 11 and a second elastic midsole 12. The first elastic midsole 11 is adhesively fixed to the wear-resistant outsole 2, and the second elastic midsole 12 is thermally fixed to the first elastic midsole 11. The rebound performance of the second elastic midsole 12 is higher than the rebound performance of the first elastic midsole 11.

[0034] Reference Figure 1 and Figure 2 In this embodiment, the sole body is made of EVA foam. The resilience of the EVA material is related to its molecular weight, vinyl acetate (VA) content, and foaming method. The higher the molecular weight of the EVA material and the higher the vinyl acetate (VA) content, the higher the elasticity of the EVA foam. In this embodiment, the molecular weight of the EVA material in the second elastic midsole 12 is greater than that in the first elastic midsole 11. This improves the resilience of the second elastic midsole 12 and makes it softer, thereby enhancing wearer comfort. Compared to the second elastic midsole 12, the first elastic midsole 11 has weaker resilience, which provides a certain degree of support for the first elastic midsole 11, ensuring that the high-rebound sole also provides good support for the wearer's foot. In other embodiments, the elastic midsole 1 can also be made of polyurethane.

[0035] Reference Figure 1 and Figure 2 When the wearer walks, the force between the wearer's sole and the high-rebound sole is relatively large. In this embodiment, along the length direction of the high-rebound sole, the thickness of the second elastic midsole 12 decreases gradually along the sole to both sides. As a result, the second elastic midsole 12 can provide greater rebound force for the wearer's foot. At the same time, the second elastic midsole 12 is relatively soft, which can improve the comfort of the wearer's foot.

[0036] Reference Figure 2 and Figure 3 At the heel of the high-rebound sole, along the direction from the tail to the toe, the first elastic midsole 11 is provided with a plurality of strip-shaped first arc-shaped protrusions 111 at intervals on one side close to the wear-resistant outsole 2. The first arc-shaped protrusions 111 are bonded and fixed to the wear-resistant outsole 2; thereby, the heel of the wear-resistant outsole 2 contacts the ground before the tail.

[0037] Reference Figure 2 and Figure 3At the heel of the high-rebound sole, along the direction from the heel to the toe, a plurality of second curved protrusions 112 are spaced apart on the side of the first elastic midsole 11 near the second elastic midsole 12. Correspondingly, the second elastic midsole 12 is provided with receiving recesses 121 for accommodating the second curved protrusions 112. This increases the connection area between the first elastic midsole 11 and the second elastic midsole 12, improving the bonding strength between the first elastic midsole 11 and the second elastic midsole 12. In this embodiment, the first elastic midsole 11 and the second elastic midsole 12 are fixed by hot-melt bonding; however, in other embodiments, the foam materials of the first elastic midsole 11 and the second elastic midsole 12 can be placed in a mold sequentially for foaming and molding.

[0038] Reference Figure 2 and Figure 3 In this embodiment, the number of the first arc-shaped protrusions 111 and the second arc-shaped protrusions 112 is the same, and the first arc-shaped protrusions 111 and the second arc-shaped protrusions 112 are arranged opposite to each other, and the outer peripheral surfaces of the first arc-shaped protrusions 111 and the second arc-shaped protrusions 112 are located on the same elliptical circumference.

[0039] Reference Figure 2 and Figure 3 Therefore, when the heel of the high-rebound sole contacts the ground, the first arc-shaped protrusion 111 and the second arc-shaped protrusion 112 are compressed to produce structural deformation; and when the high-rebound sole separates from the ground, the heel of the high-rebound sole quickly returns to its original shape, thereby improving the faster rebound force for the wearer's foot and increasing the explosiveness of the rebound of the high-rebound sole.

[0040] Reference Figure 2 and Figure 3 The sole of the wear-resistant outsole 2 has a larger contact area with the ground, thereby increasing the anti-slip effect of the high-rebound sole. The wear-resistant outsole 2 is made of wear-resistant rubber, and the wear-resistant outsole 2 is provided with anti-slip convex patterns on the side away from the elastic middle and low sides to improve the anti-slip performance of the wear-resistant outsole 2.

[0041] Example 2

[0042] The difference between this embodiment 2 and embodiment 1 is that:

[0043] Reference Figure 4The high-rebound sole also includes a corrugated steel plate 3, located at the heel of the high-rebound sole. In this embodiment, the corrugated steel plate 3 is vertically arranged and comprises a first component 31 and a second component 32, which are integrally formed. The first component 31 is embedded in the first elastic midsole 11, and the second component 32 is embedded in the second elastic midsole 12. This further enhances the connection strength between the first and second elastic midsoles 11 and 12. Furthermore, the corrugated steel plate 3 is positioned between two adjacent second arc-shaped protrusions 112. Consequently, when the wearer's heel interacts with the ground, the vertically arranged corrugated steel plate 3 undergoes significant deformation. This further increases the rebound speed and resilience of the heel of the high-rebound sole when it separates from the ground.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
