Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole high-rebound 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 of the shoe. This impact force can easily cause certain damage to the athlete's knee and / or ankle joints. Therefore, shoes are footwear that protect the legs and feet from injury, and the rebound and shock-absorbing function of shoes is very important and necessary.

[0003] Many shoes currently on the market with rebound and shock-absorbing features typically utilize improvements in the sole material or structure. For example, they employ foamed thermoplastic polyurethane materials and incorporate air columns and shock-absorbing pads. However, current rebound and shock-absorbing soles often exhibit significant hysteresis during intense exercise, failing to meet user needs. Utility Model Content

[0004] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and to provide a high-rebound sole structure and a sole, which have the advantages of rapid rebound and excellent shock-absorbing performance.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Technical Solution 1: A high-rebound structure for a sole, comprising: a support assembly, which has several support layers arranged in the up-down direction, and is provided with a rebound layer that extends continuously and obliquely from top to bottom toward the circumferential side, the rebound layer being arched and isolating the support layers on its upper and lower sides; and an outer covering layer that closes the outer side of the support assembly; in the support assembly, for each of the support layers, mutually perpendicular arrangement directions and channel directions are defined, and each of the support layers is provided with several support channels arranged in sequence along the arrangement direction, and each of the support channels 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.

[0007] Technical solution 2 based on technical solution 1: the top of the resilience layer is closed to separate the support assembly into an upper support portion located on its upper side and a lower support portion located on its lower side.

[0008] Technical solution three based on technical solution two: the top of the resilience layer is connected to the top wall of the outer covering layer.

[0009] Technical solution 4 based on technical solution 3: the bottom edge of the resilience layer is connected to the bottom wall or side wall of the outer covering layer.

[0010] Technical solution five based on any one of technical solutions one to four: in each support layer of the support assembly, the support channel is formed by two opposite side walls arranged along the arrangement direction corresponding to the support layer; the side walls are periodically arranged with a first curved segment and a second curved segment connected end to end along the channel direction corresponding to the support layer in which they are located, and the bending directions of the first curved segment and the second curved segment are opposite; between the two adjacent side walls in the same support layer, the positions of their respective first curved segments are staggered, and the positions of their respective second curved segments are also staggered.

[0011] Technical solution six based on technical solution five: in the same supporting layer, the adjacent side walls have a tendency to lean closer to each other as they are closer to the junction of the 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 side wall is connected to the end point of the first curved section of the other adjacent side wall that is staggered therewith, and the starting point of the second curved section of the side wall is connected to the end point of the second curved section of the other adjacent side wall that is staggered therewith, so that the support channels in the adjacent supporting layers are connected.

[0012] Technical Solution 7 based on Technical Solution 6: The starting and ending points of the first curved section and the second curved section in the side wall are 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 side wall are the same, and the corresponding inclination directions in adjacent side walls are opposite.

[0013] Technical solution eight based on technical solution seven: the closer the side wall is to the junction of adjacent support layers, the greater its curvature.

[0014] In addition, the present invention also provides technical solution nine: a sole that adopts the high-rebound structure of the sole as described in any one of technical solutions one to eight.

[0015] Technical solution 10 based on technical solution 9: the high-rebound structure of the sole is applied to the heel of the sole.

[0016] 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:

[0017] Technical solution 1 provides a high-rebound sole structure, which includes a support assembly and an outer covering layer. The support assembly is provided with a support layer and a rebound layer, and the outer covering layer seals the outer side of the support assembly, thereby forming a seal. The support layer within the support assembly is provided with a support channel, which can accommodate air. The channel directions of the support channels of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected. When the support assembly is subjected to downward pressure, the support assembly will be squeezed as a whole, thereby compressing the air in the support channel. When the pressure is removed, the air will return to its original volume. In this process, the compression and recovery of the air will play a certain shock-absorbing role.

[0018] At the same time, the adjacent support layers in the vertical direction support each other, and because the support channels of the adjacent support layers are intertwined, when the support assembly is squeezed, the force is quickly and evenly distributed throughout the entire support assembly, thereby providing a better shock absorption effect through the entire support assembly;

[0019] In addition, a rebound layer is provided in the support assembly, which continuously tilts toward the circumference from top to bottom to form an arched structure, and the rebound layer is provided between the support layers, thereby isolating the support layers on the upper and lower sides of the rebound layer; when the support assembly is subjected to force, due to the arched shape characteristics of the rebound layer, the rebound layer will be subjected to force through the support layer and expand to the circumference, at this time the rebound layer will accumulate elastic potential energy, and when the force is removed, the rebound layer will quickly recover the deformation, thereby making the rebound speed of the high-rebound structure of the sole faster; and, the upper surface of the rebound layer will receive the force applied by the support layer above it, and the rebound layer will transmit the force to the support layer below it, which is equivalent to quickly and evenly dispersing the force applied to the support assembly to the entire support layer assembly through the rebound layer, thereby providing better rebound and shock-absorbing effects through the entire support assembly; at the same time, the rebound layer will also play a role in pulling the support layer in the horizontal direction, thereby improving the support performance of the support layer and better absorbing impact energy.

[0020] In technical solution two, the top of the rebound layer is closed, thereby separating the support assembly into an upper support part and a lower support part. In this process, since the rebound layer divides the entire support assembly into two isolated parts, the upper support part and the lower support part can independently compress and restore the air inside, which is equivalent to dividing the support assembly into two smaller spaces to form a chamber, making the compression and recovery of the air faster. The overall rebound rate of the high-rebound structure of the sole is also faster, and the rebound and shock-absorbing effects are better.

[0021] In technical solution three, the top of the rebound layer is connected to the top wall of the outer covering layer. When the top wall of the outer covering layer receives external force, it can directly transfer the force to the rebound layer, and then transfer the force to the lower support part through the rebound layer. At the same time, the upper support part will also receive this force, thereby forming a rapid transmission of force, thereby improving the overall rebound and shock absorption performance of the high-rebound structure of the sole.

[0022] In technical solution four, the bottom edge of the rebound layer is connected to the bottom wall or side wall of the outer covering layer. The outer covering layer is used to limit the boundary of the rebound layer to prevent the rebound layer from excessive outward deformation. At the same time, the rebound layer can also transfer the force of the top wall of the outer covering layer to the side wall or bottom wall of the outer covering layer, thereby improving the overall support performance of the high-rebound structure of the sole.

[0023] In technical solution five, a support channel is formed by the cooperation of the side walls, and a first curved section and a second curved section are provided on the side walls. Compared with the straight side walls, the curved side walls have a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the side walls themselves can form a certain support, which can then be fed back to the entire support assembly to improve the shock-absorbing effect of the sole rebound boosting structure.

[0024] In technical solution six, in the same support layer, adjacent side walls have a tendency to lean closer, and there are connected parts between adjacent side walls. The mutually leaning structure makes the force transmission faster and can make the supporting performance of the side walls better. The adjacent 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.

[0025] In technical solution seven, the first curved section and the second curved section are inclined, which can make it easier for adjacent 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.

[0026] In technical solution eight, the curvature of the side wall closer to the support layer is increased, which can make the connection between adjacent side walls smoother, avoid sudden structural changes, and enhance the resilience of the support assembly.

[0027] Technical solution nine provides a sole that adopts the above-mentioned high-rebound structure of the sole, has a faster rebound rate and better shock-absorbing support performance.

[0028] In technical solution ten, the high-rebound structure of the sole is applied to the heel of the sole. When a user jumps and lands wearing shoes with the sole, the heel with the high-rebound structure can better absorb the impact energy and provide rapid rebound. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] In the claims, specification and the above drawings of the present utility model, unless otherwise clearly defined, if the terms "fixed connection" or "fixed connection" are used, they should be understood in a broad sense, that is, any connection method without any displacement relationship and relative rotation relationship between the two parties, that is to say, including non-detachable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or elements.

[0043] In the claims, description and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0044] The embodiment of the utility model relates to a high-rebound sole structure, which can be applied to a sole and used as a midsole of the sole. This embodiment is mainly described with the high-rebound sole structure as the main body.

[0045] Reference Figure 1 The high-rebound sole structure involved in this embodiment includes a support assembly 10 and an outer covering layer 20, wherein the support assembly 10 is arranged with several support layers in the up-down direction, and is provided with a rebound layer 11 that extends continuously and obliquely from top to bottom toward the circumferential side. The rebound layer 11 is arched and isolates the support layers above and below it; the outer covering layer 20 closes the outside of the support layer assembly.

[0046] In this embodiment, the high-resilience sole structure is produced using 3D printing. The material used can be a thermoplastic polyurethane elastomer (TPU). Commercially available TPU materials include Detron AU, Covestro UT-AU, and Lubrizol BF-. Alternatively, nylon can be used, with the material grade selected based on actual needs. It should be understood that in this embodiment, when the sole rebound boosting structure is made of different materials, their cushioning performance will inevitably differ, but this difference will not affect the sole rebound boosting structure's ability to achieve its function.

[0047] Furthermore, the materials used for the support assembly 10 and the outer cover 20 can be the same or different, and the materials used for the outer cover 20 can also vary at different locations. For example, the top wall of the outer cover 20 can be made of a more elastic material, while the bottom wall of the outer cover 20 can be made of a harder material. Furthermore, the material of the support assembly 10 can also be different from that of the outer cover 20, without affecting the functionality of the sole's rebound-boosting structure. However, it should be noted that the outer cover 20 should be an airtight material. When it covers the top, bottom, and sides of the support assembly 10, it can form a sealed air chamber with the support assembly 10.

[0048] The support assembly 10 is arranged with several support layers in the vertical direction. The uppermost and lowermost support layers are both enclosed by the outer covering layer 20. The outer covering layer 20 also encloses the surroundings of the support assembly. For each support layer, mutually perpendicular arrangement directions and channel directions are defined. Each support layer is provided with several support channels 12 arranged in sequence along the arrangement direction. Each support channel 12 located in the same support layer extends along the channel direction. Adjacent support layers are interconnected, and their corresponding arrangement directions are mutually perpendicular, and the channel directions are also mutually perpendicular. In addition, referring to Figure 2 and Figure 3 The resilient layer 11 in the support assembly 10 divides each support layer in the support assembly 10 into two parts in the vertical direction. Because the resilient layer 11 extends continuously from top to bottom and circumferentially, it separates support layers at different heights at different positions in the radial direction, and also separates support layers belonging to the same layer. Therefore, although the resilient layer 11 divides the support layers of the same layer into different upper and lower parts, the two parts still belong to the same support layer.

[0049] First, the structure of the support layer in the high-resilience structure of the sole according to the embodiment of the present invention will be described in detail below.

[0050] In each supporting layer of the supporting assembly 10, the supporting channel 12 is formed by two opposite side walls 13 arranged along the arrangement direction corresponding to the supporting layer; the side walls 13 are periodically arranged with first curved segments 14 and second curved segments 15 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 14 and the second curved segments 15 are opposite; between the two adjacent side walls 13 in the same supporting layer, the positions of their respective first curved segments 14 are staggered, and the positions of their respective second curved segments 15 are also staggered.

[0051] In the same supporting layer, adjacent side walls 13 have a tendency to lean closer to each other as they approach the junction 16 of the adjacent supporting layers; and at the junction 16 of adjacent supporting layers, in the same supporting layer, the starting point of the first curved section 14 of the side wall 13 is connected to the end point of the first curved section 14 of the other adjacent side wall 13 that is staggered therewith, and the starting point of the second curved section 15 of the side wall 13 is connected to the end point of the second curved section 15 of the other adjacent side wall 13 that is staggered therewith, so that the support channels 12 in the adjacent supporting layers are connected.

[0052] The starting points and end points of the first curved section 14 and the second curved section 15 in the side wall 13 are inclined along the extension direction of the corresponding support channel 12, and the corresponding inclination directions of the first curved section 14 and the second curved section 15 in the same side wall 13 are the same, and the corresponding inclination directions in adjacent side walls 13 are opposite.

[0053] The closer the side wall 13 is to the joint 16 of the adjacent support layers, the greater the curvature thereof.

[0054] Among them, Figure 1 The orientation shown is a reference, defining the top and the bottom, and defining mutually perpendicular arrangement directions and channel directions in the horizontal direction. The arrangement directions and channel directions here are relative to each supporting layer, and are not absolute directions.

[0055] Reference Figure 2 and Figure 3 , which is a schematic cross-sectional view of the high-resilience structure of the sole involved in this embodiment at different height positions in the horizontal direction, Figure 2 The cross section in Figure 3 Since the sole rebound boosting structure provided in this embodiment is prepared by 3D printing, the structure is built by stacking layers from bottom to top, and this specification also describes the structure in this way.

[0056] Reference Figure 2The portion within the outline is the support layer. The main body of the support layer is the sidewalls 1342 used to form the support channel 1241. The space between the two sidewalls 1342 is the support channel 1241. Although the sidewalls 1342 have a curved structure, the support channel 1241 generally extends in a fixed direction, which is the channel direction of the support layer.

[0057] At the same time, refer to Figure 4 , which shows the structure of the bottom support layer in the high-resilience structure of the sole. The bottom support layer includes a plurality of support channels 1241, which are arranged along a fixed direction, that is, the arrangement direction corresponding to the support layer. Figure 4 As an example, in this top view, there are left-right direction and front-back direction. Here, the front-back direction is Figure 3 The up and down direction in the diagram is defined as the front-to-back direction to distinguish it from the above-mentioned up and down direction. At this time, the channel direction of the bottom support layer is the front-to-back direction, and the arrangement direction is the left-to-right direction. Figure 5 , which also shows the structure of the bottom support layer of the high rebound structure of the sole, Figure 4 The difference is that Figure 5 The support layer in Figure 4 The support layers in the stack are higher and closer to the penultimate support layer.

[0058] Reference Figure 6 , which shows the penultimate support layer in the high-rebound sole structure. It can be seen that in this support layer, the channel direction changes to left-right, and the arrangement direction changes to up-down. This shows that for adjacent support layers, the channel direction and arrangement direction change periodically. At the same time, adjacent support layers are interconnected, so the support layers above the rebound layer 11 are interconnected, and the support layers below the rebound layer 11 are also interconnected.

[0059] Reference Figure 4 The sidewall 13 is periodically arranged with a first curved segment 14 and a second curved segment 15, connected end to end, along the front-to-back direction, that is, the direction of the passageway of the support layer. Taking the sidewall 13 marked therein as an example, starting from the front end, the first curved segment 14, the second curved segment 15, the first curved segment 14, the second curved segment 15, and so on are arranged in sequence to the rear end. The first curved segment 14 starts from the front end and smoothly curves forward, tilting to the left. The second curved segment 15 starts from the end point of the first curved segment 14 and smoothly curves backward and to the right. The starting point of the first curved segment 14 and the end point of the second curved segment 15 are at the same position in the left-right direction. Thus, the sidewall 13 forms a periodic curved structure.

[0060] The support channel 12 is formed by the cooperation of the side walls 13, and a first curved section 14 and a second curved section 15 are provided on the side walls 13. Compared with the straight side walls 13, the curved side walls 13 have a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the side walls 13 themselves can form a certain support, which can then be fed back to the entire support assembly 10, thereby improving the shock-absorbing effect of the sole rebound boosting structure.

[0061] At the same time, refer to Figure 4 On the other side wall 13 to the left of the marked side wall 13, that is, the side wall 13 adjacent to the marked side wall 13, the first curved section 14 and the second curved section 15 are staggered. The staggered position here means that the starting point of the first curved section 14 of the marked side wall 13 roughly corresponds to the end point of the corresponding first curved section 14 of the adjacent side wall 13 in the front-to-back direction. This correspondence in position does not mean that they are completely aligned, but rather that there is a certain inclination, so that the side wall 13 is tilted in the front-to-back direction.

[0062] Reference Figure 5 The side walls 13 of the bottom support layer are gradually stacked upward. As can be seen in the figure, the starting and ending points of the first and second curved segments 14, 15 of the side walls 13 of the support layer are inclined along the extension direction of the corresponding support channel 12. In the bottom support layer, the starting and ending points of the first and second curved segments 14, 15 of the marked side wall 13 are inclined toward the rear side, while the starting and ending points of the first and second curved segments 14, 15 of the other side wall 13 adjacent to the marked side wall 13 are inclined toward the front side. In this way, in the same support layer, adjacent side walls 13 tend to be closer to each other as they approach the junction 16 of the adjacent support layer.

[0063] Reference Figure 6 , the bottom support layer and the penultimate support layer intersect. At this point, the top of the sidewall 13 of the bottom support layer begins to connect with the adjacent sidewall 13. This connection occurs where the starting point of the first curved segment 14 on one sidewall 13 meets the end point of the first curved segment 14 on the other sidewall 13, and the starting point of the second curved segment 15 on one sidewall 13 meets the starting point of the second curved segment 15 on the other sidewall 13. At this junction 16, the sidewall 13 of the penultimate support layer begins to extend horizontally. After this, the sidewalls 13 of the penultimate support layer gradually incline toward each other until they connect, forming a junction 16.

[0064] In the same support layer, adjacent side walls 13 tend to lean closer, and there are connecting parts between adjacent side walls 13. The mutually leaning structure allows for faster force transmission and better support performance of the side walls 13. The adjacent side walls 13 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 support performance and improving the overall shock absorption effect. The first curved section 14 and the second curved section 15 are inclined, which can make it easier for adjacent side walls 13 to connect as a whole, and the connecting positions are staggered, reducing the impact of excessive stress concentration, thereby improving the overall shock absorption effect. The greater the degree of curvature of the side wall 13 closer to the support layer connection 16, the smoother the connection between adjacent side walls 13 can be, avoiding sudden structural changes and enhancing the resilience of the support assembly 10.

[0065] Reference Figure 2 or Figure 3 , which shows the structure of the rebound layer 11 at different height sections, while referring to Figure 1 As can be seen, the resilient layer 11 has an arched structure, with the upper surface of the resilient layer 11 connected to the support layer above it, and the lower surface of the resilient layer 11 connected to the support layer below it. The arched structure of the resilient layer 11 can be compared to an inverted bowl for easier understanding.

[0066] The rebound layer 11 is continuously inclined toward the circumference from top to bottom to form an arched structure, and the rebound layer 11 is arranged between the support layers, thereby isolating the support layers above and below the rebound layer 11; when the support assembly 10 is subjected to force, due to the arched shape of the rebound layer 11, the rebound layer 11 will be subjected to force through the support layer and expand to the circumference, at this time the rebound layer 11 will accumulate elastic potential energy, and when the force is removed, the rebound layer 11 will quickly recover the deformation, thereby making the rebound speed of the high-rebound structure of the sole faster; and the upper surface of the rebound layer 11 will receive the force applied by the support layer above it, and the rebound layer 11 will transmit the force to the support layer below it, which is equivalent to quickly and evenly dispersing the force applied to the support assembly 10 to the entire support layer assembly through the rebound layer 11, thereby providing better rebound and shock-absorbing effects through the entire support assembly 10; at the same time, the rebound layer 11 will also play a role in pulling the support layer in the horizontal direction, thereby improving the support performance of the support layer and better absorbing impact energy.

[0067] As one aspect of the high-rebound structure of the sole involved in the present invention, when the top of the rebound layer 11 is an open structure, that is, the rebound layer 11 has an opening at the center position, the support layer in the support assembly 10 will not be isolated by the rebound layer 11. Only in the part with the rebound layer 11, the support layer will be separated by the rebound layer 11.

[0068] Alternatively, as another aspect of the high-rebound sole structure of the present invention, the top of the rebound layer 11 is closed to separate the support assembly 10 into an upper support portion 18 located on its upper side and a lower support portion 17 located on its lower side. Figure 1 , Figure 1 In the high-rebound sole structure shown, the top of the rebound layer 11 is closed. The closed structure here means that there is no opening in the middle of the rebound layer 11, and it extends continuously around the circumference, and is a fully closed structure in the circumferential direction. This arrangement allows the upper support portion 18 and the lower support portion 17 to be connected only through the rebound layer 11 and the outer covering layer 20. In this case, since the rebound layer 11 divides the entire support assembly 10 into two isolated parts, the upper support portion 18 and the lower support portion 17 can each independently compress and restore the air inside, which is equivalent to dividing the support assembly 10 into two smaller spaces to form a chamber, making the compression and recovery of the air faster. The overall rebound rate of the high-rebound sole structure is also faster, and the rebound and shock-absorbing effects are better.

[0069] In addition, refer to Figure 2 or Figure 3 The top of the rebound layer 11 is in contact with the top wall of the outer covering 20, and the bottom edge of the rebound layer 11 is in contact with the bottom wall or side wall 13 of the outer covering 20. When the top wall of the outer covering 20 receives an external force, the force can be directly transferred to the rebound layer 11, and then transmitted to the lower support portion 17 through the rebound layer 11. At the same time, the upper support portion 18 also receives this force, thereby forming a rapid force transmission, improving the overall rebound and shock-absorbing performance of the sole high-rebound structure. At the same time, the outer covering 20 defines the boundary of the rebound layer 11, preventing the rebound layer 11 from excessive outward deformation. At the same time, the rebound layer 11 can also transmit the force on the top wall of the outer covering 20 to the side wall 13 or bottom wall of the outer covering 20, thereby improving the overall support performance of the sole high-rebound structure.

[0070] The high-rebound sole structure of the present invention includes a support assembly 10 and an outer covering 20. The support assembly 10 is provided with a support layer and a rebound layer 11. The outer covering 20 seals the outer side of the support assembly 10, thereby forming a seal. The support layer in the support assembly 10 is provided with a support channel 12, which can accommodate air. The support channels 12 of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected. When the support assembly 10 is subjected to downward pressure, the support assembly 10 is squeezed as a whole, thereby compressing the air in the support channel 12. When the pressure is removed, the air returns to its original volume. In this process, the compression and recovery of the air play a certain role in cushioning. At the same time, the adjacent support layers in the vertical direction support each other. Since the support channels 12 of the adjacent support layers are intertwined, when the support assembly 10 is squeezed, the force received is quickly and evenly distributed throughout the entire support assembly 10, thereby providing a better cushioning effect through the entire support assembly 10.

[0071] In addition, an embodiment of the present invention also relates to a sole, which adopts the above-mentioned sole rebound boosting structure, so that the sole has a better wearing feel and shock-absorbing support performance.
