Description
Technical Field
[0001] The utility model relates to the technical field of soles, in particular to a high-resilience sole with an inflation tube and a shoe. Background Art
[0002] By inserting an air cushion into the sole, the overall rebound and shock-absorbing performance of the sole can be improved. The wall shell that forms the air cushion is made of soft material. On this basis, the air cushion is inflated so that the air cushion can use air to form support, compress the air when under pressure, and provide rebound and shock-absorbing performance through the recovery of internal pressure. However, if the wall shell strength of the air cushion is too small, the force applied to the air cushion when under pressure will cause the air cushion to be unable to effectively compress the internal air, resulting in a large degree of deformation of the air cushion, which will not only lead to a decrease in the rebound and shock-absorbing performance of the air cushion, but also easily cause the wall shell of the air cushion to be damaged and the air cushion to explode; if the wall shell strength of the air cushion is too large, the air cushion will not be able to form an effective deformation when under pressure, which will also lead to a decrease in its rebound and shock-absorbing performance. Therefore, it is necessary to accurately adjust the strength of the air cushion wall shell so that it can achieve a good balance between the two performance requirements of having sufficient performance to compress the air and having good deformation, but this is often difficult to adapt to the actual needs of users of different weights. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A high-rebound sole with an inflation tube, comprising: a midsole, a bottom wall of which is provided with at least one group of mounting grooves extending continuously and connected to its side walls, the mounting grooves being located at the forefoot portion, the midwaist portion and / or the heel portion of the midsole; at least one inflation tube, which is embedded and installed in each mounting groove in a one-to-one correspondence, and is adapted to the corresponding mounting groove in size so that its tube wall is in close contact with the inner wall surface of the mounting groove; the first end of the inflation tube located in the mounting groove is closed, and the second end thereof extends out from an opening where the mounting groove is connected to the side wall of the midsole and is provided with an air nozzle, and the air nozzle is used to inflate the inflation tube unidirectionally; and an outsole, which is composited with the midsole and covers the bottom wall of the midsole, and the depth of the mounting groove and the size of the inflation tube are configured to be suitable for making the tube wall of the inflation tube in close contact with the top wall of the outsole.
[0006] Furthermore, the cross-sectional shape of the outer wall of the inflation tube is circular.
[0007] Furthermore, the upper side of the cross section of the mounting groove is in an arc shape that matches the upper side of the outer wall of the inflation tube, and the lower side of the cross section is in a straight line shape that matches the top wall of the outsole.
[0008] Furthermore, the shapes of both sides of the cross section of the installation groove in the horizontal direction are straight lines extending in the vertical direction.
[0009] Furthermore, a group of the mounting grooves are provided on the bottom wall of the midsole, and an inflation tube is installed in the mounting groove. The mounting groove has a first end corresponding to the inflation tube as its end point and a second end corresponding to the inflation tube as its starting point. The starting point of the mounting groove is located at the rear end of the midsole, and the end point is located at the middle waist of the midsole. The mounting groove starts from its starting point, bends and wraps around at the heel of the midsole, and then extends from the bottom wall of the midsole close to the outer side to the forefoot of the midsole, and bends and wraps around at the forefoot of the midsole to its end point.
[0010] Furthermore, a group of the mounting grooves are provided on the bottom wall of the midsole, and an inflation tube is installed in the mounting groove. The mounting groove has a first end corresponding to the inflation tube as its end point and a second end corresponding to the inflation tube as its starting point. The starting point of the mounting groove is located at the rear end of the midsole, and the end point is located at the middle waist of the midsole. The mounting groove starts from its starting point, gradually extends inward from the outer position of the bottom wall of the midsole from the heel part of the midsole to the forefoot part and then goes back to the heel part, and goes back and forth until its end point.
[0011] Furthermore, the bottom wall of the midsole is provided with two groups of the mounting grooves, and an inflation tube is installed in each group of the mounting grooves, one group of the mounting grooves is located at the heel portion of the midsole, and the other group of the mounting grooves is located at the forefoot portion of the midsole, and the two groups of the mounting grooves are bent and wrapped around at their respective positions; the starting point of the mounting groove located at the heel portion is located at the rear end position of the midsole; the starting point of the mounting groove located at the forefoot portion is located at the front end position or side position of the midsole.
[0012] Furthermore, the installation groove includes a portion extending in the front-to-back direction and a portion extending in the left-to-right direction on the bottom wall of the midsole to form a curved structure and increase the area occupied by the inflation tube installed therein on the bottom wall of the midsole.
[0013] In addition, the utility model also provides a shoe, which comprises a shoe upper and a high-resilience sole with an inflation tube as described in any one of the above items, wherein the shoe upper is compounded with the sole.
[0014] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. The utility model provides a high-resilience sole with an inflatable tube, wherein a mounting groove is arranged on the bottom wall of the midsole of the sole, an inflatable tube is embedded and installed in the mounting groove, and an outsole is compounded on the bottom surface of the midsole so that the inflatable tube is sealed in the mounting groove through the outsole; the inflatable tube can be inflated unidirectionally through an air nozzle to make the inflatable tube full and have a certain air pressure, and by placing the inflatable tube filled with air in the midsole, when the sole is pressurized, the inflatable tube can be used as an air cushion to improve the rebound performance and shock absorption performance of the sole, and because it is a long strip of pipe fittings, compared with ordinary flat full-palm air cushions or half-palm air cushions, the inflatable tube can be arranged at different positions of the midsole as needed, and has higher flexibility; at the same time, arranging the inflatable tube in the mounting groove not only controls the inflatable tube through the mounting groove, but also can improve the stability of the inflatable tube. The position is limited by the groove wall of the mounting groove and the top wall of the outsole to limit the expansion ratio of the inflatable tube when inflated. Therefore, the strength setting accuracy requirement for the tube wall of the inflatable tube itself is reduced. Even if the expansion ratio of the inflatable tube is large when inflated, the inflatable tube will not expand at an excessive ratio under the limitation of the groove wall of the mounting groove and the top wall of the outsole. Therefore, the maximum expansion ratio of the inflatable tube can be adjusted by adjusting the size of the mounting groove. In addition, the inflatable tube itself is an inflatable structure. In the event of air leakage during long-term use, it can be inflated by an external inflating device. The internal air pressure of the inflatable tube can also be adjusted during the inflation process, thereby adjusting the rebound performance and shock absorption performance of the inflatable tube attached to the midsole, so as to better adapt to different application scenarios and the actual needs of users of different weights.
[0016] 2. The cross-sectional shape of the outer wall of the inflatable tube is set to be circular. When the inflatable tube expands, it can expand evenly from all directions to ensure that the force at each position of the inflatable tube is uniform. In addition, when the circular inflatable tube is compressed, it can increase the contact area with the outsole, so that the force of the inflatable tube can be better transmitted to the outsole under different force conditions, and then transmitted to the ground.
[0017] 3. The shape of the upper position of the mounting groove is set to an arc shape that matches the shape of the inflation tube, and the lower position is set to a straight line shape that matches the outsole. During the inflation process, the inflation tube can be evenly restricted by the groove wall of the mounting groove to avoid abnormal deformation of the inflation tube. At the same time, the straight line shape of the lower position can prevent the inflation tube from being affected by the mounting groove, so that the inflation tube can better contact the top wall of the outsole. The outsole can better limit the expansion of the inflation tube and can also achieve better force transmission to the outsole.
[0018] 4. The two sides of the installation groove are in a straight line to avoid excessive restrictions on the expansion of the inflation tube. The installation groove can keep the expansion of the inflation tube in a relatively balanced state.
[0019] 5. A set of mounting grooves and an adaptive air tube are provided on the bottom wall of the midsole. The mounting grooves are bent and wrapped around the heel and forefoot parts of the midsole to increase the area occupied by the air tube in these two parts, thereby providing better rebound and shock-absorbing performance in these two parts.
[0020] 6. A group of mounting grooves and an adapted inflation tube are arranged on the bottom wall of the midsole. The mounting grooves are arranged to reciprocate from the outside to the inside of the entire palm part of the midsole, so that the entire palm part can have better rebound and shock-absorbing performance.
[0021] 7. Two sets of mounting grooves and two matching air tubes are provided on the bottom wall of the midsole. The two air tubes are independently provided at the heel and forefoot of the midsole. The air pressure of the two air tubes can be adjusted to meet the different requirements of the midsole for rebound and shock absorption performance in different parts.
[0022] 8. The installation groove extends forward and backward and left and right to form a curved structure, thereby increasing the area occupied by the inflation tube at the corresponding position.
[0023] 9. The utility model also provides a pair of shoes, which, by adopting the above-mentioned high-resilience sole with an inflatable tube, can improve the situation that the existing air cushion sole is difficult to adapt to the actual needs of users of different weights.

[0038] Example 1
[0039] Reference Figure 1 Embodiment 1 of the utility model provides a high-resilience sole with an inflation tube 20 , and the high-resilience sole mainly includes a midsole 10 , an inflation tube 20 and an outsole 30 .
[0040] Among them, the bottom wall of the midsole 10 is provided with at least one group of mounting grooves 14 extending continuously and connected with its side walls, and the mounting grooves 14 are located in the forefoot part 11, the middle waist part 12 and / or the heel part 13 of the midsole 10; at least one inflation tube 20, which is embedded and installed in each mounting groove 14 one by one, and is adapted to the corresponding mounting groove 14 in size so that its tube wall is close to the inner wall surface of the mounting groove 14; the first end 21 of the inflation tube 20 located in the mounting groove 14 is closed, and the second end 22 thereof extends from the opening where the mounting groove 14 is connected with the side wall of the midsole 10 and is provided with an air nozzle 23, and the air nozzle 23 is used to inflate the inflation tube 20 unidirectionally; and the outsole 30, which is compounded with the midsole 10 and covers the bottom wall of the midsole 10, and the depth of the mounting groove 14 and the size of the inflation tube 20 are configured to be suitable for making the tube wall of the inflation tube 20 close to the top wall of the outsole 30.
[0041] Specifically, the material of the midsole 10 is not limited here, and the composition structure of the midsole 10 is not limited here. The requirements for the material and composition structure of the midsole 10 are that the material of the midsole 10 itself needs to have good stability to have a good limiting effect on the expansion of the inflation tube 20. Generally speaking, commonly used foamed sole materials, such as PE foamed materials, EVA foamed materials, etc. can be used as the above-mentioned midsole 10.
[0042] The installation groove 14 can be provided by cutting a groove on the bottom wall of the midsole 10 after the midsole 10 is formed, or by directly providing a corresponding convex ridge on the mold during the molding process of the midsole 10, so as to form the installation groove 14 in one step. In this embodiment, the method of directly forming the installation groove 14 is adopted, and the manufacturing efficiency is higher. Multiple groups of installation grooves 14 can be provided on the midsole 10, and each group of installation grooves 14 extends continuously, that is, a group of installation grooves 14 refers to a groove-like structure that extends continuously without interruption. In addition to extending at the bottom wall position of the midsole 10, each group of installation grooves 14 is also connected to the side wall of the midsole 10. The connection here can be considered that the installation groove 14 forms an opening at the side wall position of the midsole 10, so that the inflation tube 20 can extend from the position of the opening.
[0043] The inflatable tube 20 can be made of silicone, TPU or other soft materials. When not inflated, the inflatable tube 20 can maintain its own structural shape, but it is easy to deform. Only when it is inflated, the structural stability of the inflatable tube 20 itself is improved, and a greater force is required to deform, such as being more difficult to bend. It will provide greater pressure feedback when under pressure and can rebound quickly. The number of inflatable tubes 20 installed in a midsole 10 is the same as the number of groups of mounting grooves 14, and each inflatable tube 20 corresponds to the length and size of a mounting groove 14. In other words, for a midsole 10, multiple groups of mounting grooves 14 can be set, and the length, size and extension shape of each group of mounting grooves 14 can be different, and corresponding to each group of mounting grooves 14, there is an inflatable tube 20 that can be installed in the mounting groove 14, and the length and size of the corresponding inflatable tube 20 can be adapted to the mounting groove 14. For example, a wider mounting groove 14 can be provided at the heel portion 13 of the midsole 10, and the larger diameter air tube 20 can be adapted to provide a better shock absorption effect; while a smaller mounting groove 14 can be provided at the forefoot portion 11 of the midsole 10, and the smaller diameter air tube 20 can be adapted to provide a better rebound effect. Figure 1 and Figure 3 The inflatable tube 20 is installed in the corresponding mounting groove 14 in an embedded manner, that is, the inflatable tube 20 is initially fixed by friction through the adaptation relationship between the sizes of the inflatable tube 20 and the mounting groove 14, rather than being fixed by glue bonding, so as to avoid the glue bonding affecting the expansion process of the inflatable tube 20.
[0044] The first end 21 of the inflation tube 20 is a closed end. Figure 4 The second end 22 of the inflation tube 20 extends from the opening position between the mounting groove 14 and the side wall, and the second end 22 is also provided with an air nozzle 23, through which the inflation tube 20 can be inflated unidirectionally. Each inflation tube 20 is provided with an air nozzle 23 to be inflated independently. When multiple inflation tubes 20 are provided on the midsole 10, multiple air nozzles 23 will be provided accordingly. The position where the air nozzle 23 is provided should avoid the bottom of the midsole 10 to avoid affecting the normal use of the sole.
[0045] Reference Figure 2, the outsole 30 is compounded to the midsole 10, and it can not only cover the bottom wall of the midsole 10, but also cover part or all of the side walls of the midsole 10, so as to play a limiting role on the part where the air tube 20 is provided. The outsole 30 can be fixed to the midsole 10 by bonding, hot melting, etc., and the outsole 30 needs to be closely attached to the bottom wall of the midsole 10, and the size of the air tube 20 and the depth of the mounting groove 14 must also be adapted so that the tube wall of the air tube 20 can be closely attached to the top wall of the outsole 30. Therefore, the size of the air tube 20 is adapted to the size of the mounting groove 14, not only in terms of the width of the mounting groove 14, but also in terms of the depth of the mounting groove 14, so as to avoid the inflatable tube 20 being embedded too deeply and unable to be closely attached to the outsole 30.
[0046] Reference Figure 2 The cross-sectional shape of the outer wall of the inflation tube 20 is circular, and the shape of the upper side of the cross-sectional shape of the mounting groove 14 is an arc shape that matches the shape of the upper side of the outer wall of the inflation tube 20, and the shape of the lower side of the cross-sectional shape is a straight line that matches the shape of the top wall of the outsole 30, and at the same time, the shapes of the two side positions of the cross-sectional shape of the mounting groove 14 in the horizontal direction are both straight lines extending in the vertical direction.
[0047] Specifically, the inflation tube 20 is a tube with a circular cross-section. When the inflation tube 20 expands, it can expand evenly from all directions to ensure that the force at all positions of the inflation tube 20 is uniform. In addition, when the circular inflation tube 20 is compressed, it can increase the contact area with the outsole 30, so that the force of the inflation tube 20 can be better transmitted to the outsole 30 under different force conditions, and then transmitted to the ground.
[0048] In the same group of mounting grooves 14, the cross-sectional shape and size are the same. For all mounting grooves 14, the upper side of the cross section of the mounting groove 14 is an arc segment, and the parameters of the arc segment match the shape of the corresponding inflation tube 20. Of course, the matching here means that the size of the arc segment is roughly equivalent to the size of the inflation tube 20 when it is not inflated. After the inflation tube 20 is inflated, the side wall of the mounting groove 14 will inevitably deform to a certain extent, and at this time, the arc segment of the mounting groove 14 can also fit more closely to the outer wall of the inflation tube 20. The lower side of the mounting groove 14 is a notch, and the notch is a straight line segment in cross section. During the inflation process, the inflation tube 20 can be evenly restricted by the groove wall of the mounting groove 14 to avoid abnormal deformation of the inflation tube 20. At the same time, the straight line shape of the lower side can prevent the inflation tube 20 from being affected by the mounting groove 14, so that the inflation tube 20 can better contact the top wall of the outsole 30, and the outsole 30 can better restrict the expansion of the inflation tube 20, and can also achieve better force transmission to the outsole 30. In addition, the left and right side walls of the mounting groove 14 are straight lines in cross section, avoiding excessive restrictions on the expansion of the inflation tube 20, and the expansion of the inflation tube 20 by the mounting groove 14 can be kept in a relatively balanced state.
[0049] Reference Figure 1 In this embodiment, a group of the mounting grooves 14 are provided on the bottom wall of the midsole 10, and an air tube 20 is installed in the mounting groove 14. The mounting groove 14 has an end point 141 corresponding to the first end 21 of the air tube 20, and a starting point 142 corresponding to the second end 22 of the air tube 20. The starting point 142 of the mounting groove 14 is located at the rear end of the midsole 10, and the end point 141 is located at the middle waist portion 12 of the midsole 10. The mounting groove 14 starts from its starting point 142, bends and wraps around at the heel portion 13 of the midsole 10, and extends from the bottom wall of the midsole 10 close to the outer portion to the forefoot portion 11 of the midsole 10, and bends and wraps around at the forefoot portion 11 of the midsole 10 to its end point 141. A group of mounting grooves 14 and an adaptive air tube 20 are provided on the bottom wall of the midsole 10. The mounting groove 14 is bent and wrapped around the heel portion 13 and the forefoot portion 11 of the midsole 10 to increase the occupied area of the air tube 20 in these two portions, thereby providing better rebound and shock-absorbing performance in these two portions.
[0050] The above-mentioned bending and wrapping means that the installation groove 14 includes a portion extending along the front-to-back direction and a portion extending along the left-to-right direction on the bottom wall of the midsole 10, so as to form a bending and wrapping structure and increase the area occupied by the inflation tube 20 installed therein on the bottom wall of the midsole 10.
[0051] For example, Figure 1Taking the arrangement of the mounting groove 14 shown as an example, the starting point 142 of the mounting groove 14 is at the middle position of the rear end of the midsole 10, and then extends forward along the left edge of the midsole 10, bends to the right and backward after reaching the mid-waist portion 12, and then alternately bends to the left and to the right until it reaches the rear position of the heel portion 13, and then extends upward along the right edge of the midsole 10 until it extends to the forefoot portion 11 of the midsole 10, and then alternately bends to the right and to the left until it reaches the mid-waist portion 12, forming the end point 141 of the mounting groove 14.
[0052] The high-resilience sole with an inflatable tube 20 provided in the present embodiment has an installation groove 14 on the bottom wall of the midsole 10 of the sole, in which the inflatable tube 20 is embedded and installed, and an outsole 30 is compounded on the bottom surface of the midsole 10, so that the inflatable tube 20 is enclosed in the installation groove 14 through the outsole 30; the inflatable tube 20 can be inflated unidirectionally through the air nozzle 23, so that the inflatable tube 20 is full and has a certain air pressure, and by placing the inflatable tube 20 filled with air in the midsole 10, when the sole is under pressure, the inflatable tube 20 can be used as an air cushion to improve the rebound performance and shock absorption performance of the sole, and because it is a long strip of pipe, compared with an ordinary full-palm air cushion or half-palm air cushion that is spread out flat, the inflatable tube 20 can be set at different positions of the midsole 10 as needed, which has higher flexibility; at the same time, setting the inflatable tube 20 in the installation groove 14 not only can The position of the inflatable tube 20 is limited, or the expansion ratio of the inflatable tube 20 when inflated is limited by the groove wall of the mounting groove 14 and the top wall of the outsole 30. Therefore, the strength setting accuracy requirement for the tube wall of the inflatable tube 20 itself is reduced. Even if the expansion ratio of the inflatable tube 20 when inflated is large, the inflatable tube 20 will not expand at an excessive ratio under the limitation of the groove wall of the mounting groove 14 and the top wall of the outsole 30. Therefore, the maximum expansion ratio of the inflatable tube 20 can be adjusted by adjusting the size of the mounting groove 14. In addition, the inflatable tube 20 itself is an inflatable structure. In the event of leakage during long-term use, it can be inflated by an external inflating device. The internal air pressure of the inflatable tube 20 can also be adjusted during the inflation process, thereby adjusting the rebound performance and shock absorption performance of the inflatable tube 20 attached to the midsole 10, so as to better adapt to different application scenarios and the actual needs of users of different weights.
[0053] Example 2
[0054] The difference between Example 2 of the utility model and Example 1 is that the arrangement of the mounting grooves 14 on the midsole 10 is different.
[0055] In this embodiment, the bottom wall of the midsole 10 is provided with a group of the mounting grooves 14, and an air tube 20 is installed in the mounting groove 14. The mounting groove 14 corresponds to the first end 21 of the air tube 20 as its end point 141, and corresponds to the second end 22 of the air tube 20 as its starting point 142. The starting point 142 of the mounting groove 14 is located at the rear end of the midsole 10, and the end point 141 is located at the middle waist part 12 of the midsole 10. The mounting groove 14 starts from its starting point 142, gradually extends from the outer position of the bottom wall of the midsole 10 to the inward from the heel part 13 of the midsole 10 to the forefoot part 11 and back to the heel part 13, and reciprocates until its end point 141. The bottom wall of the midsole 10 is provided with a group of mounting grooves 14 and an adapted air tube 20. The mounting groove 14 reciprocates from the outside to the inside of the whole palm part of the midsole 10, so that the whole palm part can have good rebound and shock absorption performance.
[0056] Specifically, the starting point 142 of the mounting groove 14 is at the middle position of the rear end of the midsole 10, and then extends forward along the right edge of the midsole 10 to the forefoot portion 11, then smoothly bends to the left to reach the left edge of the midsole 10, and then extends backward along the left edge of the midsole 10 to the heel portion 13, and then smoothly and completely reaches the position of the mounting groove 14 located on the outside to the right, and then extends forward along the extension direction of the mounting groove 14 on the outside to the forefoot portion 11, and repeatedly circles until it reaches the end point 141 located at the mid-waist position.
[0057] Example 3
[0058] The difference between Example 3 of the present invention and Example 1 is that the arrangement of the mounting grooves 14 on the midsole 10 is different.
[0059] In this embodiment, the bottom wall of the midsole 10 is provided with two groups of the mounting grooves 14, and each group of the mounting grooves 14 is provided with an air tube 20, wherein one group of the mounting grooves 14 is located at the heel portion 13 of the midsole 10, and the other group of the mounting grooves 14 is located at the forefoot portion 11 of the midsole 10, and both groups of the mounting grooves 14 are bent and wound around at their respective positions; the starting point 142 of the mounting groove 14 located at the heel portion 13 is located at the rear end position of the midsole 10; the starting point 142 of the mounting groove 14 located at the forefoot portion 11 is located at the front end position or the side position of the midsole 10.
