Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole with high-rebound anti-torsion support multifunctional structure and a sole. Background Art

[0002] With the development of society and the continuous improvement of people's material living standards, more and more people pay attention to their health and participate in more sports and fitness in their daily lives. During sports such as running, due to inertia, the moment the sole of the athlete's shoe touches the ground, the sole is subjected to downward pressure from the body's own weight and a counter-impact force (generally equivalent to 3 to 5 times the body weight) exerted on it by the bottom surface. This impact force can easily cause certain damage to the athlete's knee and / or ankle joints and other human structures. Therefore, shoes are footwear that protect the legs and feet from injury, and the cushioning function of shoes is very important and necessary.

[0003] Many cushioning shoes currently on the market rely on improvements to the sole material or structure. For example, they use foamed thermoplastic polyurethane, a material with excellent cushioning properties, and incorporate air cushions and cushioning columns. However, these soles offer poor torsional resistance in sports like basketball that require sudden stops and changes of direction, failing to effectively protect the user's foot.

[0007] Technical solution 2 based on technical solution 1: in each supporting layer of the first supporting part, the supporting channel is formed by two opposite second side walls arranged along the arrangement direction corresponding to the supporting layer; the second side wall is periodically arranged with first and second curved segments connected end to end along the channel direction corresponding to the supporting layer in which it is located, and the bending directions of the first and second curved segments are opposite; between two adjacent second side walls in the same supporting layer, the positions of their respective first curved segments are staggered, and the positions of their respective second curved segments are also staggered.

[0008] Technical solution three based on technical solution two: in the same supporting layer, adjacent second side walls have a tendency to lean closer to each other as they are closer to the junction of adjacent supporting layers; and at the junction of adjacent supporting layers, in the same supporting layer, the starting point of the first curved section of the second side wall is connected to the end point of the first curved section of another adjacent second side wall that is staggered with it, and the starting point of the second curved section of the second side wall is connected to the end point of the second curved section of another adjacent second side wall that is staggered with it, so that the support channels in adjacent supporting layers are connected.

[0009] Technical solution four based on technical solution three: the starting and ending points of the first curved section and the second curved section in the second side wall are both inclined along the extension direction of the corresponding support channel, and the corresponding inclination directions of the first curved section and the second curved section in the same second side wall are the same, and the corresponding inclination directions in adjacent second side walls are opposite.

[0010] Technical solution 5 based on technical solution 4: The closer the side wall is to the junction of adjacent support layers, the greater its curvature.

[0011] Technical solution six based on technical solution one: the cross-sectional shape of each support unit of the second support portion in the horizontal direction is consistent, and the cross-sectional shape is configured to be suitable for forming a planar paving in the second support portion.

[0012] Technical solution seven based on technical solution six: the cross-sectional shape of each support unit of the second support portion in the horizontal direction is a regular hexagon, and both sides of each first side wall serve as inner walls of adjacent support units.

[0014] In addition, the utility model also provides technical solution nine: a sole, which adopts the high-rebound and anti-torsion support multifunctional structure of the sole as described in any one of technical solutions one to eight, wherein the first support part corresponds to the forefoot part of the sole, the second support part corresponds to the heel part of the sole, and the connecting part corresponds to the arch part of the sole.

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

[0016] The multifunctional structure of the sole with high rebound and anti-torsion support provided by the technical solution 1 is provided with a support component and an outer wall, and the outer wall can close the support component, so that a closed air chamber is formed inside the support component; wherein the support component includes a first support part, a connecting part and a second support part, and the support layer in the first support part is provided with a support channel, which can accommodate air, and at the same time, the channel directions of the support channels of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected, and a closed first air chamber is formed by the closure of the outer wall; when the first support part is subjected to downward pressure, the first support part is squeezed as a whole, so that the air in the support channel is compressed, and when the pressure is removed, the air will return to its original volume. In this process, the compression and recovery of the air can play a certain role in cushioning and rebounding. At the same time, adjacent support layers will support each other, and because the support channels of adjacent support layers are in an interlaced shape, when the first support part is squeezed, the force it receives will be quickly and evenly dispersed to the entire first support part, thereby providing support through the entire first support part. It provides a better shock-absorbing effect and also has better rebound performance; at the same time, the second support part is provided with a plurality of support units, each support unit is closed by the outer wall to form a closed second air chamber, and the second support part therefore forms a plurality of second air chambers; when the second support part is under pressure, the air in each second air chamber will play a corresponding shock-absorbing role through compression and recovery. At the same time, since these second air chambers are isolated from each other, the overall deformation degree is lower than that of the first support part, so the second support part can also provide better support performance, and the first side wall used to form the support unit can also play a supporting role in the up and down directions, thereby improving the support stability of the second support part; the connecting part is solid and connects the first support part and the second support part, so that the three become a whole. At the same time, since the connecting part is a solid structure, the high-rebound and anti-torsion support multifunctional structure of the sole as a whole is less likely to twist at the position of the connecting part, thereby improving the structural stability of the first support part and the second support part, and at the same time playing a role in improving the overall anti-torsion performance of the high-rebound and anti-torsion support multifunctional structure of the sole.

[0017] In technical solution two, a support channel is formed by the cooperation of the second side wall, and a first curved section and a second curved section are provided on the second side wall. Compared with the straight second side wall, the curved second side wall has a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the second side wall itself can form a certain support, which can then be fed back to the entire first support part, thereby improving the shock-absorbing effect of the high-rebound and anti-torsion support multifunctional structure of the sole.

[0018] In technical solution three, in the same support layer, adjacent second side walls have a tendency to lean closer, and there are connected parts between adjacent second side walls. The mutually leaning structures make the force transmission faster and can make the supporting performance of the second side walls better. The adjacent second side walls are connected, which can make the connecting parts between adjacent support layers more stable and increase the equivalent contact area of ​​the connecting parts, thereby improving the supporting performance and thus improving the overall shock absorption effect.

[0019] In technical solution four, the first curved section and the second curved section are inclined, which can make it easier for adjacent second side walls to be connected as one, and the connection positions are staggered, reducing the impact of excessive stress concentration, thereby improving the overall shock absorption effect.

[0020] In technical solution five, the curvature of the second side wall closer to the support layer is increased, which can make the connection between adjacent second side walls smoother, avoid sudden structural changes, and enhance the resilience of the support assembly.

[0021] In technical solution six, the horizontal cross-section of the support unit in the second support portion is set to a shape that can form a plane-closed shape, so that the various support units in the entire second support portion are connected as one, providing better support and shock-absorbing effects.

[0022] In technical solution seven, the horizontal cross-section of the support unit is set to a regular hexagon. The shape of the support unit is regular, which facilitates the dense arrangement of the plane in the second support part, and the first side walls of the support unit can pull each other, thereby providing a better support effect.

[0023] In Technical Solution Eight, the first side wall of each support unit is composed of several arc segments arranged in the up and down directions. This structure will provide greater deformation ability in the parts of the arc segments that expand outward and contract inward, so that the support unit can have a larger deformation space, which can not only reduce the overall hardness of the second support part and provide a softer and more elastic support effect, but also provide greater rebound when the support unit recovers its deformation, and the overall cushioning effect is better; at the same time, a straight line segment is set below all the arc segments. The addition of the straight line segment can reduce the deformation ability of the support unit, and setting the straight line segment below can allow the straight line segment to directly connect with the lower side wall of the outer wall. The straight line segment has poor deformation ability, but can provide better support, and the part of the arc segment located above can provide better touch and rebound effect close to the sole of the foot, so that the second support part achieves a good balance between support performance and cushioning performance.

[0024] In technical solution nine, a sole is provided, which adopts the above-mentioned sole high-rebound and anti-torsion support multifunctional structure, and the first support part is applied to the forefoot, the second support part is applied to the heel, and the connecting part is applied to the arch of the foot. It can provide better cushioning and rebound performance in the forefoot part, and better support and stability performance in the heel part. The connecting part here not only serves to connect the first support part and the second support part, but also can provide anti-torsion performance in the arch of the foot.

[0041] Example 1

[0042] The first embodiment of the present invention provides a multifunctional structure for supporting a shoe sole with high resilience and anti-torsion, which can be applied to a shoe sole as a midsole. This embodiment is mainly described using the multifunctional structure for supporting a shoe sole with high resilience and anti-torsion.

[0043] Reference Figure 1 The multifunctional structure of the sole with high resilience and anti-torsion support provided in this embodiment includes a support component 10 and an outer wall 20. Figure 1 The internal structure of the multifunctional structure of the sole with high resilience and anti-torsion support is shown after removing part of the outer wall 20, wherein the support component 10 is Figure 1 The bright yellow part in the outer wall 20 is Figure 1 The outer wall 20 covers the periphery of the closed support assembly 10, which is the khaki part in the figure.

[0044] In this embodiment, the multifunctional high-resilience, anti-torsion support structure of the sole is fabricated using 3D printing. The material used can be thermoplastic polyurethane elastomer, which can be commercially available, such as Detron AU-brand polyurethane material, Covestro UT-AU-brand polyurethane material, and Lubrizol BF-brand polyurethane material. Alternatively, nylon can be used, and the material brand can be selected based on actual needs. It should be understood that in this embodiment, when the multifunctional high-resilience, anti-torsion support structure of the sole is made of different materials, its cushioning performance will inevitably vary, but this difference will not affect the multifunctional high-resilience, anti-torsion support structure's ability to perform its function. The materials used for the support assembly 10 and the outer wall 20 can be the same or different, and the materials used for different parts of the support assembly 10 can be the same or different. However, it should be noted that the outer wall 20 should be made of an airtight material. When the outer wall 20 covers and encloses the periphery of the support assembly 10, it can form a sealed air chamber with the support assembly 10.

[0045] Among them, the support assembly 10 is provided with a first support part 11, a connecting part 13 and a second support part 12 from front to back; the first support part 11 is arranged with several support layers in the up and down direction, and each support layer is defined with a mutually perpendicular arrangement direction and channel direction, and each support layer is provided with several support channels 115 arranged in sequence along the arrangement direction, and each support channel 115 located in the same support layer extends along the channel direction; adjacent support layers are connected to each other, and their corresponding arrangement directions are perpendicular to each other, and the channel directions are also perpendicular to each other; the second support part 12 is arranged with a plurality of mutually isolated and interconnected support units 122 in the horizontal direction, and each support unit 122 is surrounded by a first side wall 121 extending up and down; the connecting part 13 is solid, and its front and rear sides are respectively connected to and closed with the rear side of the first support part 11 and the front side of the second support part 12; the outer wall 20 covers and closes the outer periphery of the support assembly 10 to form a closed first air chamber in the first support part 11 and a plurality of closed second air chambers in the second support part 12.

[0046] Preferably, in each supporting layer of the first supporting portion 11, the supporting channel 115 is formed by two opposite second side walls 111 arranged along the arrangement direction corresponding to the supporting layer; the second side walls 111 are periodically arranged with first curved segments 112 and second curved segments 113 connected end to end along the channel direction corresponding to the supporting layer in which they are located, and the bending directions of the first curved segments 112 and the second curved segments 113 are opposite; between two adjacent second side walls 111 in the same supporting layer, the positions of their respective first curved segments 112 are staggered, and the positions of their respective second curved segments 113 are also staggered.

[0047] In the same support layer of the first support portion 11, adjacent second side walls 111 have a tendency to lean closer to each other the closer to the junction 114 of the adjacent support layers; and at the junction 114 of adjacent support layers, in the same support layer, the starting point of the first curved section 112 of the second side wall 111 is connected to the end point of the first curved section 112 of the other adjacent second side wall 111, which is staggered therewith, and the starting point of the second curved section 113 of the second side wall 111 is connected to the end point of the second curved section 113 of the other adjacent second side wall 111, which is staggered therewith, so that the support channels 115 in the adjacent support layers are connected.

[0048] The starting and ending points of the first curved section 112 and the second curved section 113 of each supporting layer's second sidewall 111 are inclined along the extension direction of the corresponding supporting channel 115. The first curved section 112 and the second curved section 113 of the same second sidewall 111 have the same inclination direction, while the corresponding inclination directions of adjacent second sidewalls 111 are opposite. Furthermore, the closer the second sidewall 111 is to the junction 114 of adjacent supporting layers, the greater its curvature.

[0049] Furthermore, in the second support portion 12, each support unit 122 of the second support portion 12 has a consistent horizontal cross-sectional shape, and the cross-sectional shape is configured to form a planar tiling in the second support portion 12. Furthermore, each support unit 122 of the second support portion 12 has a regular hexagonal cross-sectional shape in the horizontal direction, and both sides of each first side wall 121 serve as inner walls of adjacent support units 122.

[0050] Reference Figure 1 ,by Figure 1 The coordinate system shown indicates the direction and refers to Figures 2 to 6 , Figures 2 to 6 All of them are top views, and mutually perpendicular arrangement directions and channel directions are defined in the horizontal direction. The arrangement directions and channel directions here are relative to each supporting layer, and are not absolute directions.

[0051] The multifunctional structure of the sole with high resilience and anti-torsion support provided in this embodiment is made by stacking layers in a 3D printing manner. As a whole, the structure is built by gradually stacking layers from bottom to top. Therefore, this embodiment also uses the corresponding layer-by-layer laying method to illustrate the structure of the support assembly 10. Figures 2 to 6 Diagrams showing the different stages of laying from the bottom layer upwards in the order of laying and stacking.

[0052] First, the structure of the first supporting portion 11 will be described in detail below.

[0053] Reference Figure 1 The first support portion 11 is located at the front side of the sole high rebound anti-torsion support multifunctional structure. The first support portion 11 is composed of several support layers arranged up and down. Figure 2 The main body of the support layer is the second side wall 111 for forming the support channel 115, and the space between the two second side walls 111 is the support channel 115. Figure 2 ,Will Figure 2The support layer shown is the first support layer. Although the second side wall 111 has a curved structure, the support channels 115 generally extend in a fixed direction, which is the channel direction of the support layer. At the same time, the first support layer includes a plurality of support channels 115, which are arranged along a fixed direction, which is the corresponding arrangement direction of the support layer. Figure 2 Taking the paper direction as an example, the channel direction of the first layer of the support layer is the left-right direction, and the arrangement direction is the up-down direction. Figure 5 , which shows the structure of a second support layer located above and adjacent to the first support layer. In this second support layer, the channel direction changes to vertical, and the arrangement direction changes to left-right. This shows that for adjacent support layers, the channel direction and arrangement direction change periodically. At the same time, adjacent support layers are interconnected. When the outer wall 20 encloses the entire support assembly 10, the first support portion 11 as a whole forms a sealed first air chamber, within which the aforementioned support layer is located.

[0054] Reference Figure 2 and Figure 3 ,by Figure 2 and Figure 3 Taking the paper direction as an example, in the first support layer, the second side wall 111 is periodically arranged with first curved segments 112 and second curved segments 113 connected end to end along the left-right direction, that is, the channel direction of this support layer. Taking one of the second side walls 111 as an example, starting from the left end, the first curved segment 112, the second curved segment 113, the first curved segment 112, the second curved segment 113, and so on are arranged in sequence to the rightmost end. The first curved segment 112 starts from the left end and smoothly bends forward and tilts to the right. The second curved segment 113 starts from the end point of the first curved segment 112 and smoothly bends backward and tilts to the right. The starting point of the first curved segment 112 and the end point of the second curved segment 113 are at the same position in the front-to-back direction. As a result, the second side wall 111 forms a periodic curved structure.

[0055] At the same time, continue to refer to Figure 2 and Figure 3 Taking the second side wall 111 as an example, the positions of the first curved sections 112 and the second curved sections 113 of the adjacent second side wall 111 below or above the second side wall 111 are offset. The offset here means that within the left-right range defined by the starting and ending points of the first curved section 112 or second curved section 113 of one second side wall 111, the starting or ending points of the first curved section 112 or second curved section 113 of the adjacent second side wall 111 are not within the left-right range. In other words, the curved sections of adjacent second side walls 111 are not completely opposite each other.

[0056] Reference Figure 3 and Figure 4 The second side wall 111 of the first supporting layer is gradually laid upwards to form the structure. Figure 3 It can be seen that the starting and ending points of the first curved section 112 and the second curved section 113 in the second side wall 111 of the support layer are inclined along the extension direction of the corresponding support channel 115, and in the first support layer, the starting and ending points of the first curved section 112 and the second curved section 113 of a second side wall 111 are inclined toward the left, and the starting and ending points of the first curved section 112 and the second curved section 113 of another second side wall 111 adjacent to the second side wall 111 are inclined toward the right. In this way, in the same support layer, adjacent second side walls 111 have a tendency to lean closer to each other the closer they are to the junction 114 of the adjacent support layer. Figure 4 , the first support layer and the second support layer intersect, at this time, the top of the second side wall 111 of the first support layer begins to connect with the adjacent second side wall 111, and the connecting position is that the starting point of the first curved section 112 on the second side wall 111 connects with the end point of the first curved section 112 on the other second side wall 111, and the starting point of the second curved section 113 on the second side wall 111 connects with the starting point of the second curved section 113 on the other second side wall 111. Figure 4 As an example, at the position of the junction 114, the second side wall 111 of the second support layer begins to extend in the vertical direction. Figure 5 The second side wall 111 of the second support layer gradually extends upward, and the degree of curvature gradually decreases, and the main part of the second side wall 111 extends in the vertical direction. Figure 6 The second side walls 111 of the second support layer will gradually lean towards each other until they are connected to form a joint 114 .

[0057] The support layer in the above-mentioned first support part 11 is provided with a support channel 115, which can accommodate air. At the same time, the channel directions of the support channels 115 of adjacent support layers are perpendicular to each other, and the adjacent support layers are connected to each other, and a closed first air chamber is formed by the closure of the outer wall 20; when the first support part 11 is subjected to downward pressure, the first support part 11 is squeezed as a whole, so that the air in the support channel 115 is compressed. When the pressure is removed, the air will restore its original volume. In this process, the compression and recovery of the air can play a certain shock-absorbing role. At the same time, adjacent support layers will support each other, and because the support channels 115 of adjacent support layers are in a staggered shape, when the first support part 11 is squeezed, the force it receives will be quickly and evenly dispersed to the entire first support part 11, thereby providing a better shock-absorbing effect through the entire first support part 11, and also having better rebound performance.

[0058] The structure of the second supporting portion 12 will be described in detail below.

[0059] Reference Figure 1 The second support portion 12 is located at the rear side of the support assembly 10. The second support portion 12 is formed by a plurality of support units 122 in a planar paving manner. Each support unit 122 is formed by a first side wall 121. The first side wall 121 is formed along Figure 1 As shown, the first sidewall 121 extends in the vertical direction, and adjacent support units 122 are separated by the first sidewall 121, while at the same time being connected in the overall space by the first sidewall 121. When the outer wall 20 covers and closes the support assembly 10, the upper and lower ends of the support units 122 in the second support portion 12 are enclosed by the outer wall 20, forming a plurality of enclosed second air chambers in the second support portion 12.

[0060] Reference Figures 2 to 6 The first sidewall 121 does not change position during vertical installation, so the support units 122 can be considered as a columnar structure extending vertically. Furthermore, each support unit 122 has a consistent horizontal cross-sectional shape, resulting in substantially consistent support and shock-absorbing performance for each support unit 122, thus providing greater functional consistency for the entire second support portion 12. Furthermore, the cross-sectional shape of each support unit 122 is configured to form a densely packed planar structure within the second support portion 12. This means that the second support portion 12 is completely horizontally occupied by support units 122, with no gaps remaining. This results in enhanced support and shock-absorbing performance for the entire second support portion 12.

[0061] In this embodiment, each support unit 122 of the second support portion 12 has a regular hexagonal cross-section in the horizontal direction, which can form a planar tessellation of the structure. The regular hexagon itself also has good support performance. At the same time, both sides of each first side wall 121 serve as the inner walls of the adjacent support unit 122. In other words, each first side wall 121 is shared by adjacent support units 122.

[0062] The second support portion 12 is provided with a plurality of support units 122, each support unit 122 is closed by the outer wall 20 to form a closed second air chamber, and the second support portion 12 is therefore formed with a plurality of second air chambers; when the second support portion 12 is pressurized, the air in each second air chamber will play a corresponding shock-absorbing role through compression and recovery. At the same time, since these second air chambers are isolated from each other, the overall deformation degree is lower than that of the first support portion 11, so the second support portion 12 can also provide better supporting performance, and the first side wall 121 used to form the support unit 122 can also play a supporting role in the up and down directions, thereby improving the supporting stability of the second support portion 12

[0063] The structure of the connecting portion 13 will be described in detail below.

[0064] Reference Figure 1 The connecting portion 13 is located in the middle of the support assembly 10. Its front and rear sides connect the first support portion 11 and the second support portion 12 respectively, and seal the rear side of the first support portion 11 and the front side of the second support portion 12. This allows the first air chamber and the second air chamber near the connecting portion 13 to be constructed, and the support assembly 10 is integrated, effectively improving the overall support performance of the high-resilience and anti-torsion support multifunctional structure of the sole. The connecting portion 13 is a solid structure. At the location of the connecting portion 13, the high-resilience and anti-torsion support multifunctional structure of the sole is less likely to twist, thereby improving the structural stability of the first support portion 11 and the second support portion 12, while also improving the anti-torsion performance of the high-resilience and anti-torsion support multifunctional structure of the sole.

[0065] In addition, the present invention also provides another embodiment, which is a sole. The sole adopts the above-mentioned sole high-rebound and anti-torsion support multifunctional structure, wherein the first support part 11 corresponds to the forefoot part of the sole, the second support part 12 corresponds to the heel part of the sole, and the connecting part 13 corresponds to the arch part of the sole.

[0066] Specifically, the midsole of the sole adopts the above-mentioned high-rebound and anti-torsion support multifunctional structure of the sole, wherein the first support part 11 is applied to the forefoot, the second support part 12 is applied to the heel, and the connecting part 13 is applied to the arch of the foot. It can provide better cushioning and rebound performance in the forefoot, and better support and stability performance in the heel. The connecting part 13 here not only serves to connect the first support part 11 and the second support part 12, but also can provide anti-torsion performance in the arch of the foot.

[0067] Example 2

[0068] The present invention further provides Example 2. The difference between Example 2 and Example 1 is that the structure of the support unit 122 in the second support portion 12 is different.

[0069] Reference Figure 7 Each support unit 122 of the second support portion 12 is a rotating body formed around a vertically extending longitudinal axis, with its circumference surrounded by the first side wall 121, and its upper and lower ends are respectively connected to the outer wall 20 to form the second air chamber; the first side wall 121 of each support unit 122 forms a plurality of arc segments 123 from top to bottom on a vertical cross-section passing through its longitudinal axis, and forms a straight line segment 124 below all the arc segments 123, the lower end of the straight line segment 124 is connected to the lower side wall surface of the outer wall, and the upper end is connected to the lower end of the arc segment 123 located at the bottom; wherein, some of the arc segments 123 extend obliquely from top to bottom toward the outer side of the support unit 122, and some of the arc segments 123 extend obliquely from top to bottom toward the inner side of the support unit 122, and the extension directions of the arc segments 123 adjacent to each other in the vertical direction are opposite.

[0070] The first side wall 121 of each support unit 122 is composed of a number of arc segments 123 arranged in the up-down direction. This structure provides greater deformation ability in the parts of the arc segments 123 that expand outward and contract inward, so that the support unit 122 can have a larger deformation space, which can not only reduce the overall hardness of the second support part 12 and provide a softer and more elastic support effect, but also provide greater rebound when the support unit 122 recovers its deformation, and the overall cushioning effect is better; at the same time, a straight line segment 124 is arranged below all the arc segments 123. The addition of the straight line segment 124 can reduce the deformation ability of the support unit 122, and the straight line segment 124 is arranged below, so that the straight line segment 124 can be directly connected to the lower side wall of the outer wall 20. The straight line segment 124 has poor deformation ability, but can provide better support, and the part of the arc segment 123 located above can provide better touch and rebound effect near the sole of the foot, so that the second support part 12 achieves a good balance between support performance and cushioning performance.
