Description

Technical Field

[0001] The present invention relates to the technical field of shoe soles, in particular to a shoe 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. 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 shoes currently on the market with shock-absorbing features rely on improvements to the sole material or structure. For example, they use foamed thermoplastic polyurethane, a material with excellent shock-absorbing properties, and incorporate air cushions and shock-absorbing columns. However, improvements to the sole material require different shock-absorbing properties at different locations on the sole, and soles made of the same material cannot meet these requirements. Improvements to the sole structure also result in a stiff overall structure and low comfort. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and provide a sole that can improve the cushioning effect and wearing comfort of the sole.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] Technical Solution 1: A sole cushioning support structure, comprising: a support assembly, which is arranged with several support layers in the up and down directions, and each support layer is defined with an arrangement direction and a channel direction perpendicular to each other, and each support layer is provided with several support channels arranged in sequence along the arrangement direction, and each support channel 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; a protruding support platform is formed by the support layer at the top middle position of the support assembly, and a shock-absorbing table surface lower than the support platform is formed on the peripheral side of the support platform; and an outer wall, which covers the periphery of the support assembly to enclose the support assembly to form an enclosed air chamber; the sole cushioning support structure is applied to the forefoot of the sole, and the bottom of the support assembly is in the shape of an arc extending from front to back, which protrudes downward, and the thickness of one end of the support assembly in the front-to-back direction is greater than the thickness of the other end.

[0007] Technical solution 2 based on technical solution 1: the support platform and the shock-absorbing table surface are smoothly transitioned between the two by adjusting the heights of the corresponding support layers.

[0008] Technical solution three based on technical solution two: 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.

[0009] Technical solution four based on technical solution three: 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.

[0010] Technical solution five based on technical solution four: 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.

[0011] Technical solution 6 based on technical solution 5: The closer the side wall is to the junction of adjacent support layers, the greater its curvature.

[0012] In addition, the present invention also provides technical solution seven: a sole that adopts the sole buffering support structure as described in any one of technical solutions one to six.

[0013] Technical Solution 8 based on Technical Solution 7: The sole buffer support structure is applied to the forefoot of the sole, and the bottom of the support component is in the shape of an arc extending from front to back, and the arc bulges downward.

[0014] 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:

[0015] In the sole cushioning support structure provided by Technical Solution 1, a support component and an outer wall are provided, 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 is provided with a plurality of support layers, and the support layers are provided with support channels, 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 air cushion part is subjected to downward pressure, the first air cushion 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 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 since the support channels of adjacent support layers are in a staggered form, when When the first air cushion portion is squeezed, the force it receives will be quickly and evenly dispersed throughout the entire first air cushion portion, thereby providing a better cushioning effect through the entire first air cushion portion, and also having better rebound performance; at the same time, a support platform and a cushioning surface are formed by the support assembly, the support platform protrudes from the cushioning surface, and the support platform is the part that directly contacts the foot; when the protruding support platform is squeezed by the foot, its shape will change, thereby transferring the force to the bottom and sides, and the cushioning surface plays the role of receiving the force transmitted by the support platform, so that the support platform will not undergo too drastic deformation, thereby enabling the support platform to maintain sufficient structural stability for support; therefore, through the cooperation of the support platform and the cushioning surface, the sole buffering support structure can provide a softer foot feel while having a better support effect.

[0016] In the second technical solution, the support platform and the shock-absorbing surface are smoothly transitioned by adjusting the height of the corresponding support layer. When the support platform is subjected to force, the deformation of the support platform is more moderate, and the force can be better transmitted to the shock-absorbing surface.

[0017] In technical solution three, 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 buffer support structure.

[0018] In technical solution four, 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.

[0019] In technical solution five, 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.

[0020] In technical solution six, 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.

[0021] In technical solution seven, a sole is provided, which adopts the above-mentioned sole buffering support structure, so that it has better wearing feel and shock-absorbing support performance.

[0022] In Technical Solution 8, the bottom of the support component is made into a downward convex arc shape. When applied to the forefoot part of the sole, it can better fit the shape of the forefoot and the physiological curvature of the foot, providing users with better foot feel and shock-absorbing support performance.

[0038] An embodiment of the present invention provides a sole cushioning support structure, which can be applied to a sole and used as a midsole of the sole. This embodiment is mainly described using the sole cushioning support structure.

[0039] Reference Figure 1 and Figure 2 , which shows the appearance of the sole cushioning support structure provided by this embodiment, a support platform 21 and a shock absorbing table 22 are provided on the top of the sole cushioning support structure. Figure 3 The sole cushioning support structure provided in this embodiment includes a support assembly 10 and an outer wall 30. Figure 3 The internal structure of the sole cushioning support structure after removing part of the outer wall 30 is shown, wherein the support assembly 10 is Figure 3 The bright yellow part in the outer wall 30 is Figure 3 The outer wall 30 covers the periphery of the closed support assembly 10, which is the khaki part in the figure.

[0040] In this embodiment, the sole cushioning support structure is prepared by 3D printing, and the material used can be thermoplastic polyurethane elastomer. Thermoplastic polyurethane elastomer materials can be selected from commercially available products, such as Detron AU brand polyurethane materials, Covestro UT-AU brand polyurethane materials, and Lubrizol BF- brand polyurethane materials. Alternatively, the material used can also be nylon, and the material brand can be selected according to actual needs. It should be understood that in this embodiment, when the sole cushioning support structure is made of different materials, there will inevitably be differences in their shock absorption performance, but this difference will not affect the sole cushioning support structure from achieving its function. Among them, the materials used for the support assembly 10 and the outer wall 30 can be the same or different, and the materials used for different parts inside the support assembly 10 can be the same or different. However, it should be noted that the outer wall 30 should be made of an airtight material. When the outer wall 30 covers the outer periphery of the closed support assembly 10, it can cooperate with the support assembly 10 to form a sealed air chamber.

[0041] Reference Figures 4 to 7The support assembly 10 is provided with a plurality of support layers 11 arranged in the up and down directions, and a mutually perpendicular arrangement direction and channel direction are defined for each of the support layers 11. Each of the support layers 11 is provided with a plurality of support channels 12 arranged in sequence along the arrangement direction, and each of the support channels 12 located in the same support layer 11 extends along the channel direction; the adjacent support layers 11 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; a protruding support platform 21 is formed by the support layer 11 at the top middle position of the support assembly 10, and a shock-absorbing table 22 lower than the support platform 21 is formed on the peripheral side of the support platform 21; the outer wall 30 covers the outer periphery of the support assembly 10 to enclose the support assembly 10 to form a closed air chamber.

[0042] Preferably, the support platform 21 and the shock absorbing table 22 are smoothly transitioned from each other by adjusting the height of the corresponding support layer 11 .

[0043] In addition, in each supporting layer 11 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 11; the side walls 13 are periodically arranged with a first curved segment 14 and a second curved segment 15 connected end to end along the channel direction corresponding to the supporting layer 11 in which they are located, and the bending directions of the first curved segment 14 and the second curved segment 15 are opposite; between the two adjacent side walls 13 in the same supporting layer 11, the positions of their respective first curved segments 14 are staggered, and the positions of their respective second curved segments 15 are also staggered.

[0044] In the same supporting layer 11, the adjacent side walls 13 have a tendency to lean closer to each other as they approach the joint 16 of the adjacent supporting layers 11; and at the joint 16 of the adjacent supporting layers 11, in the same supporting layer 11, 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, which 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, which is staggered therewith, so that the support channels 12 in the adjacent supporting layers 11 are connected.

[0045] 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.

[0046] The closer the side wall 13 is to the joint 16 of the adjacent support layers 11 , the greater the curvature thereof.

[0047] First, the structure of the support assembly 10 is described in detail below.

[0048] Since the sole cushioning support structure provided in this embodiment is made by stacking and printing in layers using 3D printing, and the structure is built by gradually stacking layers from bottom to top, this embodiment also uses the corresponding layer-by-layer laying method to illustrate the structure of the support assembly 10. Figures 4 to 7 Illustrations of the different stages of laying from bottom to top in the order of laying and stacking.

[0049] Reference Figure 3 , the support assembly 10 is composed of a plurality of support layers 11 arranged up and down; Figure 4 The main body of the support layer 11 is the side wall 13 for forming the support channel 12, and the space between the two side walls 13 is the support channel 12. Figure 4 ,Will Figure 4 The support layer 11 shown is the first support layer 11. Although the sidewall 13 has a curved structure, the support channels 12 generally extend in a fixed direction, which is the channel direction of the support layer 11. At the same time, the first support layer 11 includes a plurality of support channels 12, which are arranged along a fixed direction, which is the corresponding arrangement direction of the support layer 11. Figure 4 Taking the paper direction as an example, the channel direction of the first layer of the support layer 11 is the left-right direction, and the arrangement direction is the up-down direction. Figure 7 , which shows the structure of the second support layer 11 located above the first support layer 11. In this second support layer 11, the channel direction changes to the up-down direction, and the arrangement direction changes to the left-right direction. It can be seen that for adjacent support layers 11, their channel direction and arrangement direction change periodically. At the same time, adjacent support layers 11 are interconnected. When the outer wall 30 encloses the entire support assembly 10, the first air cushion portion as a whole forms a sealed first air chamber, inside which the above-mentioned support layer 11 is disposed.

[0050] Reference Figure 4 and Figure 5 ,by Figure 4 and Figure 5Taking the paper direction as an example, in the first support layer 11, the sidewalls 13 are periodically arranged with first and second curved segments 14, 15, connected end to end, along the left-right direction, that is, the channel direction of the support layer 11. Taking one sidewall 13 as an example, starting from the left 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 rightmost end. The first curved segment 14 starts from the left end and smoothly curves forward, tilting to the right. The second curved segment 15 starts from the end point of the first curved segment 14 and smoothly curves backward, tilting 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 front-to-back direction. Thus, the sidewalls 13 form a periodic curved structure.

[0051] At the same time, continue to refer to Figure 4 and Figure 5 Taking the side wall 13 mentioned above as an example, the positions of the first curved sections 14 and the second curved sections 15 of the adjacent side wall 13 below or above the side wall 13 are offset. The offset here means that within the left-right range defined by the starting and ending points of the first curved section 14 or second curved section 15 of one side wall 13, the starting or ending points of the first curved section 14 or second curved section 15 of the adjacent side wall 13 are not within the left-right range. In other words, the curved sections of the adjacent side walls 13 are not completely opposite each other.

[0052] Reference Figure 5 and Figure 6 The side walls 13 of the first supporting layer 11 are gradually laid upwards to form the structure. Figure 5 It can be seen that the starting and ending points of the first curved section 14 and the second curved section 15 in the side wall 13 of the support layer 11 are inclined along the extension direction of the corresponding support channel 12. Moreover, in the first layer of the support layer 11, the starting and ending points of the first curved section 14 and the second curved section 15 of one side wall 13 are inclined toward the left, while the starting and ending points of the first curved section 14 and the second curved section 15 of the other side wall 13 adjacent to the side wall 13 are inclined toward the right. In this way, in the same support layer 11, adjacent side walls 13 have a tendency to lean closer to each other the closer they are to the junction 16 of the adjacent support layers 11. Figure 6 , the first support layer 11 and the second support layer 11 intersect. At this time, the top of the side wall 13 of the first support layer 11 begins to connect with the adjacent side wall 13. The connecting position is that the starting point of the first curved section 14 on the side wall 13 connects with the end point of the first curved section 14 on the other side wall 13, and the starting point of the second curved section 15 on the side wall 13 connects with the starting point of the second curved section 15 on the other side wall 13. Figure 6As an example, at the position of the joint 16, the side wall 13 of the second support layer 11 begins to extend in the vertical direction. Figure 7 The sidewalls 13 of the second support layer 11 gradually extend upward, and the curvature gradually decreases, with the main portion of the sidewalls 13 extending in the vertical direction. Subsequently, the sidewalls 13 of the second support layer 11 gradually incline toward each other until they connect to form a joint 16.

[0053] The structure of the support assembly 10 is such that after the outer wall 30 closes the support assembly 10, a sealed air chamber can be formed inside the support assembly 10; wherein the support assembly 10 is provided with a plurality of support layers 11, and the support layers 11 are provided with support channels 12, and the support channels 12 can accommodate air, and at the same time, the channel directions of the support channels 12 of adjacent support layers 11 are perpendicular to each other, and the adjacent support layers 11 are connected to each other, and a sealed first air chamber is formed by the closure of the outer wall 30; when the first air cushion portion is subjected to downward pressure, the first air cushion portion acts as a whole The body is squeezed, so that the air in the support channel 12 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 11 will support each other, and because the support channels 12 of adjacent support layers 11 are staggered, when the first air cushion part is squeezed, the force it receives will be quickly and evenly dispersed to the entire first air cushion part, thereby providing a better shock-absorbing effect through the entire first air cushion part, and also having better rebound performance.

[0054] Reference Figure 1 and Figure 2 , at the top of the support component 10, by setting the laying position of the support layer 11, a support platform 21 is formed in the middle position. In this embodiment, there is only one support platform 21, and it matches the outer contour of the support component 10, and a shock-absorbing table surface 22 is formed in the portion between the support platform 21 and the outer contour of the support component 10. It should be understood that the support platform 21 is formed by the support layer 11. Since each support layer 11 of the support component 10 is laid layer by layer by 3D printing, when it is laid to the top position of the support component 10, the support layer 11 can continue to be laid only in the middle portion where the support platform 21 needs to be formed, and the portion where the shock-absorbing table surface 22 needs to be laid, thereby forming the above-mentioned support platform 21 and shock-absorbing table surface 22. At the same time, referring to Figure 1 and Figure 2In the transition part between the support platform 21 and the shock-absorbing table surface 22, a smooth transition is achieved by adjusting the height of the corresponding support layer 11. The adjustment of the height of the corresponding support layer 11 referred to here refers to the height of the support layer 11 between the support platform 21 and the shock-absorbing table surface 22, which gradually decreases from the support platform 21 toward the shock-absorbing table surface 22, so that the top surface of the support platform 21 can smoothly transition to the shock-absorbing table surface 22.

[0055] A support platform 21 and a shock-absorbing surface 22 are formed by the support assembly 10. The support platform 21 protrudes from the shock-absorbing surface 22, and the support platform 21 is the part that directly contacts the foot. When the protruding support platform 21 is squeezed by the foot, its shape will change, thereby transferring the force to the bottom and sides. The shock-absorbing surface 22 plays the role of receiving the force transmitted by the support platform 21, so that the support platform 21 will not undergo too drastic deformation, thereby maintaining sufficient structural stability for support. Therefore, through the cooperation of the support platform 21 and the shock-absorbing surface 22, the sole buffering support structure can provide a softer foot feel while having a better support effect.

[0056] In addition, the present invention also provides another embodiment, which is a sole. The sole adopts the above-mentioned sole buffering support structure, so it has a better wearing feel and shock-absorbing support performance.

[0057] Specifically, the forefoot portion of the midsole of the sole adopts the sole buffer support structure provided by the above-mentioned embodiment, and the arch portion and the heel portion of the midsole of the sole can adopt other materials, or components similar to the above-mentioned sole buffer support structure can be adopted throughout the entire palm. Among them, the bottom of the support component 10 is in the shape of an arc extending from front to back, and the arc protrudes downward, and the thickness of one end of the support component 10 in the front-to-back direction is greater than the thickness of the other end. Through the downward-protruding arc-shaped bottom, when the sole buffer support structure is applied to the forefoot portion of the midsole of the sole, it can better fit the shape of the forefoot pad and the physiological curvature. At the same time, it should be noted that the external shape of the sole buffer support structure needs to be modified and adjusted accordingly corresponding to the arch portion and the heel portion.

[0058] The above description and embodiments are intended to explain the scope of protection of the present invention, but do not constitute a limitation thereto. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
