Description

TECHNICAL FIELD

[0001] The utility model relates to a shoe field especially relates to a shoe heel cup, sole and the shoe containing the shoe heel cup or sole. BACKGROUND

[0002] The shoe structure generally cannot limit or guide the direction of its deformation, and generally can deform randomly or have approximately the same deformable trend in multiple directions, which is strong in universality but poor in pertinence, and cannot meet special use requirements or adapt to specific application scenarios.

[0003] The traditional shoe heel cup structure is often difficult to balance easy wearing and taking off and heel stability when wearing. In order to improve this problem, various attempts have appeared on the market, but these structures often sacrifice stability while achieving easy wearing and taking off, or are difficult to achieve easy wearing and taking off while maintaining stability.

[0004] The traditional sole elastic plate structure is usually made of a single material, which has limitations in providing comfort and support. In order to improve the performance of the sole, various composite sole structures have appeared on the market, but these structures often have deficiencies in achieving specific functions, such as easy bending to one side and difficult bending to the other side or different hardness zoning, and are difficult to adjust according to specific needs. SUMMARY

[0009] Furthermore, the thickness of the support layer is the first thickness, and the depth of the gap is the second thickness, which is less than the first thickness.

[0010] Furthermore, the flexible layer is a material with flexibility and tensile strength, the flexible layer has a first hardness, and the support layer has a second hardness, the second hardness being greater than the first hardness.

[0011] Furthermore, the flexible layer is made of at least one of fabric, polymer material, carbon fiber, glass fiber, and foam material, and the support layer is made of at least one of fabric, metal, polymer material, carbon fiber, glass fiber, and foam material.

[0012] A shoe sole, disposed at the bottom of a shoe, includes a flexible layer and a support layer stacked on top of each other. The support layer includes a plurality of support blocks and gaps disposed between the support blocks. The gaps include closed ends and open ends disposed opposite to each other. The closed ends are disposed close to the flexible layer, and the open ends are disposed away from the flexible layer, so that the support layer can be easily bent in the direction from the open end to the closed end.

[0013] Furthermore, the flexible layer includes a first surface and a third surface, and the support layer includes a second surface and a fourth surface. The third surface and the fourth surface are fitted together, the first surface faces the inside of the shoe, and the second surface faces the outside of the shoe, so that the sole can easily bend inward.

[0014] Furthermore, the flexible layer includes a first surface and a third surface, and the support layer includes a second surface and a fourth surface.

[0018] A shoe comprising the heel cup described above, or comprising the sole described above.

[0019] The shoe heel cup and sole of this utility model have the following advantages:

[0020] 1. A flexible layer and a support layer are arranged opposite to each other. Several support blocks are arranged on the support layer. There are linear gaps between each support block. The gaps include closed ends and open ends arranged opposite to each other. This allows the support layer to bend quickly in the direction from the open end to the closed end. When the support layer bends in the direction from the closed end to the open end, it will be pulled by the side of the flexible layer or the support layer closer to the flexible layer, thereby maintaining the original shape of the flexible layer and the support layer.

[0021] 2. When putting on shoes, stepping on the support layer with your heel causes the heel cup to collapse inward quickly, making it easier to put on shoes quickly;

[0022] 3. The heel cup of the shoe can bend backwards easily to better adapt to the walking process, reduce the impact on the feet, and improve walking comfort;

[0023] 4. The sole is easy to bend inward, which can improve the efficiency of the foot's forward rolling motion during the push-off phase, and facilitate the dorsiflexion and extension of the foot to improve foot comfort.

[0024] 5. The sole is easy to bend outwards. When the sole comes into contact with uneven ground, it bends outwards to quickly wrap around the ground, preventing the sole from tilting as a whole. This prevents the foot from pronation or supination and improves the stability of the body when moving on uneven ground. Attached Figure Description

[0033] To better understand the purpose, structure, and function of this utility model, the following detailed description of the shoe heel cup, sole, and shoe, in conjunction with the accompanying drawings, is provided.

[0034] like Figures 1 to 8 As shown, the heel cup of the shoe includes a flexible layer 110 and a support layer 120 arranged opposite to each other. A plurality of support blocks 21 are arranged on the support layer 120. There are linear gaps between each support block 21. The gap includes a closed end and an open end arranged opposite to each other. The closed end is arranged close to the flexible layer 110, and the open end is arranged away from the flexible layer 110. This allows the distance between the support blocks 21 on both sides of the open end to increase when the support layer 120 bends in the direction from the open end to the closed end, and the width of the gap opening end increases, which in turn facilitates the rapid bending of the support layer 120 in the direction from the open end to the closed end.

[0035] It is understandable that when the support layer 120 bends in the direction from the closed end to the open end, the support blocks 21 on both sides of the closed end are fitted together, and the flexible layer 110 opposite to the closed end pulls on the closed end to maintain its inherent shape. Therefore, the above structure is not conducive to the support layer 120 bending in the direction from the closed end to the open end. That is, when the support layer 120 is subjected to a force that makes it bend towards the open end, it will be pulled by the flexible layer 110 or the side of the support layer 120 close to the flexible layer 110, thereby maintaining the original shape of the shoe heel cup.

[0036] The sole includes a flexible layer 210 and a support layer 220 arranged opposite to each other. A plurality of support blocks 21 are arranged on the support layer 220. There are linear gaps between each support block 21. The gap includes a closed end and an open end arranged opposite to each other. The closed end is arranged close to the flexible layer 210, and the open end is arranged away from the flexible layer 210. This allows the distance between the support blocks 21 on both sides of the open end to increase when the support layer 220 bends in the direction from the open end to the closed end. This increases the width of the gap opening end, which in turn facilitates the rapid bending of the support layer 220 in the direction from the open end to the closed end.

[0037] It is understandable that when the support layer 220 bends in the direction from the closed end to the open end, the support blocks 21 on both sides of the closed end are fitted together, and the flexible layer 210 opposite to the closed end pulls on the closed end to maintain its inherent shape. Therefore, the above structure is not conducive to the support layer 220 bending in the direction from the closed end to the open end. That is, when the support layer 220 is subjected to a force that makes it bend towards the open end, it will be pulled by the flexible layer 210 or the side of the support layer 220 close to the flexible layer 210, thereby maintaining the original shape of the sole.

[0038] In summary, by using the composite structure of the flexible layer and the support layer, and by creating gaps in the support layer to divide it into multiple support blocks, the heel cup and sole of the shoe can be easily bent to one side and not easily bent to the other, depending on actual needs. This enhances the functionality of the heel cup and sole. Furthermore, by adjusting the specific structure and material of the support layer, it can adapt to different functional requirements, increasing the shoe's applicability to meet diverse wearing needs.

[0039] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, will take the specific structure of the heel cup and sole as examples to further illustrate the heel cup, sole, and shoe of this utility model.

[0040] The side of the heel counter and sole facing the human foot is defined as the inner side of the heel counter and sole, and the side of the heel counter and sole facing away from the human foot is defined as the outer side of the heel counter and sole.

[0041] Example 1, as Figure 1 and Figure 2 As shown, the heel cup extends upward from the back of the sole, corresponding to the back and sides of the human heel. The heel cup includes a flexible layer 110 and a support layer 120 that are stacked and fixedly connected. The flexible layer 110 includes a first surface and a third surface, and the support layer 120 includes a second surface and a fourth surface. The first surface faces the inside of the heel cup, the second surface faces the outside of the heel cup, and the third and fourth surfaces are fitted together. The support layer 120 includes several support blocks 21 and gaps between the support blocks 21. The gaps include closed ends and open ends that are arranged opposite each other. The closed ends are located near the third surface of the flexible layer 110, and the open ends are located on the second surface of the support layer 120, i.e., the open ends are located away from the flexible layer 110, thereby forming several gaps between the second and fourth surfaces to divide the support layer 120 into several support blocks 21.

[0042] The purpose of the above structure is that when the support layer 120 bends in the direction from the open end to the closed end, the support blocks 21 on both sides of the open end can separate from each other, thus increasing the distance between them and the width of the gap opening end. This facilitates the rapid bending of the support layer 120 in the direction from the open end to the closed end, meaning the heel cup can easily bend inwards. This allows the heel cup to quickly collapse inwards when the foot steps on the support layer 120 while wearing the shoe, facilitating quick shoe-wearing. Furthermore, when the support layer 120 bends in the direction from the closed end to the open end, the support blocks 21 on both sides of the closed end are closely fitted together, and the flexible layer 110 opposite the closed end pulls on the closed end to maintain its inherent shape, thus maintaining the original shape of the heel cup. This allows the left and right sides of the heel cup to provide inward support to the heel area, helping to maintain the stability of the heel area.

[0043] Preferably, the thickness of the support layer 120, i.e., the distance between the second and fourth surfaces of the support layer 120, is defined as the first thickness, and the depth of the gap, i.e., the distance between the open end and the closed end, is defined as the second thickness. The second thickness is then set to be less than the first thickness. The purpose of this structure is to ensure that each support block 21 maintains a connection between the closed end and the fourth surface, thereby enhancing the tensile resistance generated by the fourth surface when the support layer 120 bends in the direction from the closed end to the open end, thus strengthening the support of the heel cup for outward bending.

[0044] Furthermore, the gaps between the support blocks 21 can be formed by cutting the support layer 120, 3D printing, injection molding, printing, or 3D knitting, with the gap width as small as possible to maintain the integrity of the support layer 120 structure and improve support strength. The support blocks 21 can be designed into different geometric shapes, such as triangles or quadrilaterals, to achieve specific bending characteristics, thereby controlling the inward bending flexibility and outward bending support of the heel cup. This allows for variations in the hardness of the heel cup in different areas to adapt to different wearing needs. When there are fewer segmented support blocks 21, bending is only facilitated at the gaps, and the overall support is closer to that of a complete support layer 120. When there are more segmented support blocks 21, it becomes very flexible in the bending direction but less flexible in the opposite direction.

[0045] Understandably, the flexible layer 110 is located on the inner side of the heel cup and is made of a material with flexibility and tensile strength, making the heel cup easy to bend inwards. When the heel cup bends outwards, it provides better tensile strength and support. The flexible layer 110 has a first hardness, and the support layer 120 has a second hardness, which is greater than the first hardness, so that the heel cup is supported when it bends outwards. The support blocks 21 on the support layer 120 are spliced ​​together and cooperate with the flexible layer 110, thus having the rebound characteristics to maintain the original structure.

[0046] Preferably, the flexible layer 110 can be made of at least one of fabric, polymer material, carbon fiber, glass fiber, or foam material, and the support layer 120 can be made of at least one of fabric, metal, polymer material, carbon fiber, glass fiber, or foam material. The hardness of the above materials can be adjusted to achieve precise control of the bending characteristics of the shoe heel cup to adapt to different functional requirements.

[0047] Example 2, as Figure 3 and Figure 4As shown, the heel cup extends upward from the back of the sole, corresponding to the back and sides of the human heel. The heel cup includes a flexible layer 110 and a support layer 120 that are stacked and fixedly connected. The flexible layer 110 includes a first surface and a third surface, and the support layer 120 includes a second surface and a fourth surface. The first surface faces the outer side of the heel cup, the second surface faces the inner side of the heel cup, and the third and fourth surfaces are fitted together. The support layer 120 includes several support blocks 21 and gaps between the support blocks 21. The gaps include closed ends and open ends that are arranged opposite each other. The closed ends are located near the third surface of the flexible layer 110, and the open ends are located on the second surface of the support layer 120, i.e., the open ends are located away from the flexible layer 110, thereby forming several gaps between the second and fourth surfaces to divide the support layer 120 into several support blocks 21.

[0048] The purpose of this structure is that when the support layer 120 bends in the direction from the open end to the closed end, the support blocks 21 on both sides of the open end can separate from each other, thus increasing the distance between them and the width of the gap opening end. This facilitates the rapid bending of the support layer 120 in the direction from the open end to the closed end, meaning the heel cup of the shoe can easily bend outwards. It is understandable that when the human body walks, the heel strikes the ground first, then gradually transitions to the forefoot. During this process, the heel needs to withstand a significant impact force, which is gradually released to the forefoot. Therefore, the heel cup's ability to bend backwards better adapts to this walking process, reducing the impact on the foot and improving walking comfort.

[0049] Furthermore, when the support layer 120 bends in the direction from the closed end to the open end, the support blocks 21 on both sides of the closed end fit together, and the flexible layer 110 opposite to the closed end pulls on the closed end to maintain its inherent shape, thus maintaining the original shape of the heel cup. The heel cup is not easily bent inward, providing sufficient support and preventing accidents such as ankle sprains. This design also helps maintain the stability and durability of the shoe.

[0050] Preferably, the thickness of the support layer 120, i.e., the distance between the second and fourth surfaces of the support layer 120, is defined as the first thickness, and the depth of the gap, i.e., the distance between the open end and the closed end, is defined as the second thickness. The second thickness is then set to be less than the first thickness. The purpose of this structure is to ensure that each support block 21 maintains a connection between the closed end and the fourth surface, thereby enhancing the tensile resistance generated by the fourth surface when the support layer 120 bends in the direction from the closed end to the open end, thus strengthening the support of the heel cup for inward bending.

[0051] Furthermore, the gaps between the support blocks 21 can be formed by cutting the support layer 120, 3D printing, injection molding, printing, or 3D knitting, with the gap width as small as possible to maintain the integrity of the support layer 120 structure and improve support strength. The support blocks 21 can be designed into different geometric shapes, such as triangles or quadrilaterals, to achieve specific bending characteristics, thereby controlling the outward bending flexibility and inward bending support of the heel cup. This allows for variations in the hardness of the heel cup in different areas to adapt to different wearing needs. When there are fewer segmented support blocks 21, bending is only facilitated at the gaps, and the overall support is closer to that of a complete support layer 120. When there are more segmented support blocks 21, it becomes very flexible in the bending direction but less flexible in the opposite direction.

[0052] Understandably, the flexible layer 110 is located on the outer side of the heel cup and is made of a material with flexibility and tensile strength, making the heel cup easy to bend outwards. When the heel cup bends inwards, it provides better tensile strength and support. The flexible layer 110 has a first hardness, and the support layer 120 has a second hardness, which is greater than the first hardness, so that the heel cup is supported when it bends inwards. The support blocks 21 on the support layer 120 are spliced ​​together and cooperate with the flexible layer 110, thus maintaining the rebound characteristics of the original structure.

[0053] Preferably, the flexible layer 110 can be made of at least one of fabric, polymer material, carbon fiber, glass fiber, or foam material, and the support layer 120 can be made of at least one of fabric, metal, polymer material, carbon fiber, glass fiber, or foam material. The hardness of the above materials can be adjusted to achieve precise control of the bending characteristics of the shoe heel cup to adapt to different functional requirements.

[0054] Example 3, as Figure 5 and Figure 6 As shown, the sole includes a flexible layer 210 and a support layer 220 that are stacked and fixedly connected. The flexible layer 210 includes a first surface and a third surface, and the support layer 220 includes a second surface and a fourth surface. The first surface is disposed on the inner side of the sole, and the second surface is disposed on the outer side of the sole. The third surface and the fourth surface are fitted together opposite to each other. The support layer 220 includes a plurality of support blocks 21 and gaps disposed between the support blocks 21. The gaps include closed ends and open ends disposed opposite to each other. The closed ends are disposed near the third surface of the flexible layer 210, and the open ends are disposed on the second surface of the support layer 220, that is, the open ends are disposed away from the flexible layer 210, thereby forming a plurality of gaps between the second surface and the fourth surface to divide the support layer 220 into a plurality of support blocks 21.

[0055] The purpose of the above structure is that when the support layer 220 bends in the direction from the open end to the closed end, the support blocks 21 on both sides of the open end can separate from each other, thus increasing the distance between them and the width of the gap opening end. This facilitates the rapid bending of the support layer 220 in the direction from the open end to the closed end, meaning the sole is more likely to bend inwards, improving the efficiency of the foot's forward rolling motion during the push-off phase and enhancing foot comfort by facilitating dorsiflexion and extension. Furthermore, when the support layer 220 bends in the direction from the closed end to the open end, the support blocks 21 on both sides of the closed end are closely fitted together, and the flexible layer 210 opposite the closed end pulls on the closed end to maintain its inherent shape, thereby maintaining the original shape of the sole and helping to maintain the stability of the foot.

[0056] Preferably, the thickness of the support layer 220, i.e., the distance between the second and fourth surfaces of the support layer 220, is defined as the first thickness, and the depth of the gap, i.e., the distance between the open end and the closed end, is defined as the second thickness. The second thickness is then set to be less than the first thickness. The purpose of this structure is to ensure that each support block 21 maintains a connection between the closed end and the fourth surface at a certain distance. This enhances the tensile resistance generated by the fourth surface when the support layer 220 bends in the direction from the closed end to the open end, thereby strengthening the outward bending support of the sole.

[0057] Furthermore, the gaps between the support blocks 21 can be formed by cutting the support layer 220, 3D printing, injection molding, printing, or 3D knitting, with the gap width as small as possible to maintain the integrity of the support layer 220 structure and improve support strength. The support blocks 21 can be designed into different geometric shapes, such as triangles or quadrilaterals, to achieve specific bending characteristics, thereby controlling the inward bending flexibility and outward bending support of the sole. This allows for variations in the hardness of the sole in different areas to adapt to different wearing needs. When there are fewer segmented support blocks 21, bending is only facilitated at the gaps, and the overall support is closer to that of a complete support layer 220. When there are more segmented support blocks 21, the sole becomes very flexible in the bending direction but less flexible in the opposite direction.

[0058] Understandably, the flexible layer 210 is located on the inner side of the sole and is made of a material with flexibility and tensile strength, making the sole easy to bend inwards and providing better tensile strength and support when the sole bends outwards. The flexible layer 210 has a first hardness, and the support layer 220 has a second hardness, which is greater than the first hardness, so as to provide support when the sole bends outwards. The support blocks 21 on the support layer 220 are spliced ​​together and cooperate with the flexible layer 210, thereby having the rebound characteristics to maintain the original structure.

[0059] Preferably, the flexible layer 210 can be made of at least one of fabric, polymer material, carbon fiber, glass fiber or foam material, and the support layer 220 can be made of at least one of fabric, metal, polymer material, carbon fiber, glass fiber or foam material. The hardness of the above materials can be adjusted to achieve precise control of the bending characteristics of the shoe sole to adapt to different functional requirements.

[0060] Example 4, as Figure 7 and Figure 8 As shown, the sole includes a flexible layer 210 and a support layer 220 that are stacked and fixedly connected. The flexible layer 210 includes a first surface and a third surface, and the support layer 220 includes a second surface and a fourth surface. The first surface is disposed on the outer side of the sole, the second surface is disposed on the inner side of the sole, and the third and fourth surfaces are fitted together. The support layer 220 includes a plurality of support blocks 21 and gaps disposed between the support blocks 21. The gaps include closed ends and open ends disposed opposite to each other. The closed ends are disposed near the third surface of the flexible layer 210, and the open ends are disposed on the second surface of the support layer 220, that is, the open ends are disposed away from the flexible layer 210, thereby forming a plurality of gaps between the second surface and the fourth surface to divide the support layer 220 into a plurality of support blocks 21.

[0061] The purpose of the above structure is that when the support layer 220 bends in the direction from the open end to the closed end, the support blocks 21 on both sides of the open end can separate from each other, thus increasing the distance between them and the width of the gap opening end. This facilitates the rapid bending of the support layer 220 in the direction from the open end to the closed end, meaning the sole easily bends outward. When the sole contacts uneven ground, it bends outward, quickly wrapping around the ground to prevent the sole from tilting, thereby preventing inward or outward rotation of the foot and improving the stability of the human body when moving on uneven ground. In addition, when the support layer 220 bends in the direction from the closed end to the open end, the support blocks 21 on both sides of the closed end are closely fitted together, and the flexible layer 210 opposite to the closed end pulls on the closed end to maintain its inherent shape, thus maintaining the original shape of the sole, which is beneficial for the sole to maintain stability and quickly return to its original shape after deformation.

[0062] Preferably, the thickness of the support layer 220, i.e., the distance between the second and fourth surfaces of the support layer 220, is defined as the first thickness, and the depth of the gap, i.e., the distance between the open end and the closed end, is defined as the second thickness. The second thickness is then set to be less than the first thickness. The purpose of this structure is to ensure that each support block 21 maintains a connection between the closed end and the fourth surface, thereby enhancing the tensile resistance generated by the fourth surface when the support layer 220 bends in the direction from the closed end to the open end, thus strengthening the support of the sole for inward bending.

[0063] Furthermore, the gaps between the support blocks 21 can be formed by cutting the support layer 220, 3D printing, injection molding, printing, or 3D knitting, with the gap width as small as possible to maintain the integrity of the support layer 220 structure and improve support strength. The support blocks 21 can be designed into different geometric shapes, such as triangles or quadrilaterals, to achieve specific bending characteristics, thereby controlling the outward bending flexibility and inward bending support of the sole. This allows for variations in the hardness of the sole in different areas to adapt to different wearing needs. When there are fewer segmented support blocks 21, bending is only facilitated at the gaps, and the overall support is closer to that of a complete support layer 220. When there are more segmented support blocks 21, the sole becomes very flexible in the bending direction but less flexible in the opposite direction.

[0064] Understandably, the flexible layer 210 is located on the outer side of the sole and is made of a material with flexibility and tensile strength, making the sole easy to bend outwards. When the sole bends inwards, it provides better tensile strength and support. The flexible layer 210 has a first hardness, and the support layer 220 has a second hardness, which is greater than the first hardness, so that the sole is supported when it bends inwards. The support blocks 21 on the support layer 220 are spliced ​​together and cooperate with the flexible layer 210, thus having the rebound characteristics to maintain the original structure.

[0065] Preferably, the flexible layer 210 can be made of at least one of fabric, polymer material, carbon fiber, glass fiber or foam material, and the support layer 220 can be made of at least one of fabric, metal, polymer material, carbon fiber, glass fiber or foam material. The hardness of the above materials can be adjusted to achieve precise control of the bending characteristics of the shoe sole to adapt to different functional requirements.

[0066] This utility model also provides a shoe, including the heel cup described above, or including the sole described above. The exterior of the heel cup or sole structure, i.e., the exterior of the first and second surfaces, further includes an inner or outer layer to cover the support layer and the flexible layer. The inner layer contacts the human body to enhance the comfort of the foot, and the outer layer protects the support layer and the flexible layer, enhancing the overall durability and aesthetics of the structure.
