Description

Technical Field

[0001] This utility model relates to the field of footwear, and more particularly to a sole and a shoe containing the sole. Background Technology

[0002] Current athletic shoe soles typically employ a fixed structure design, where the rebound, cushioning, and support performance are determined during manufacturing and cannot be adjusted to meet specific user needs. This limits the adaptability and comfort of athletic shoes, especially during high-intensity exercise or different sports scenarios where users may require different sole performance to protect their feet and improve athletic performance. Therefore, current soles suffer from the drawback of not being able to adjust their rebound, cushioning, and support performance according to actual needs. Utility Model Content

[0003] The purpose of this invention is to provide a shoe sole and a shoe incorporating the sole, which allows for adjustment of the sole's rebound, cushioning, and support performance as needed by rotating an adjustment unit on the sole. The specific technical solution is as follows:

[0004] A shoe sole includes an adjustment unit, the adjustment unit including at least one adjustment module, the adjustment module including at least two functional areas with different characteristics, the adjustment module having a built-in first axis arranged in a horizontal direction, the adjustment module being rotatable around the first axis to switch the different functional areas to the vertical direction of the shoe sole, so that the pressure of the human foot can be concentrated on the functional areas located in the vertical direction.

[0005] Furthermore, the adjustment module is a cylindrical structure with a circular cross-section.

[0006] Furthermore, it also includes a limiting unit, which includes a first component and a second component disposed opposite to each other on both sides of the adjustment unit. The inner sides of the first component and the second component are disposed close to each other, and the outer sides of the first component and the second component are disposed close to each other.

[0007] Furthermore, it also includes a limiting unit, and an inner and outer wall that are arranged opposite to each other. The limiting unit includes two frames, which are respectively set on the inner and outer walls, and the two ends of the first shaft are fixedly connected to the two frames respectively.

[0008] Furthermore, the cross-sections of the adjustment modules have the same diameter.

[0009] Furthermore, the adjustment module includes a first part located on the inner side of the sole, a third part located on the outer side of the sole, and a second part connecting the first part and the third part. The diameter of the first part and the third part is a first length, and the diameter of the second part is a second length. The first length is not equal to the second length.

[0010] Furthermore, the adjustment module can be shaped like a dumbbell; or, shaped like a peanut; or, shaped like a shuttle.

[0011] Furthermore, the functional area of ​​the adjustment module includes a support section and several buffer sections disposed inside the support section. The buffer sections of each functional area have different volumes and / or different materials.

[0012] Furthermore, the material strength of the support part is greater than that of the buffer part.

[0013] Furthermore, the support portion is made of at least one of nylon, thermoplastic polyurethane, and foamed elastomer, and the interior of the cushioning portion is filled with gas and / or polyurethane.

[0014] Furthermore, the buffer sections of each functional area are circular or regular polygonal columnar structures.

[0015] Furthermore, the number of functional areas with the same characteristics is set to two, and the two functional areas are set as mirror images with the first axis as the axis of symmetry.

[0016] Furthermore, the adjustment module includes two first functional areas, two second functional areas, and two third functional areas, all mirror images of each other with the first axis as the axis of symmetry. The elasticity of the first functional area is greater than that of the second functional area, and the elasticity of the second functional area is greater than that of the third functional area.

[0017] Furthermore, the adjustment unit also includes several protruding ribs, which are spaced apart and arranged around the outside of the adjustment module.

[0018] Furthermore, it also includes a forefoot area, a midfoot area, and a heel area that are sequentially connected, with an adjustment unit provided on at least one of the forefoot area, midfoot area, and heel area.

[0019] A shoe comprising the sole described above.

[0020] The sole of this invention has the following advantages:

[0021] 1. By setting an adjustment unit on the sole, the adjustment module in the adjustment unit includes at least two functional areas with different characteristics. When in use, the functional areas are rotated to different angles around the first axis set horizontally, so that the different functional areas switch positions in the vertical direction of the sole, thereby concentrating the pressure of the human foot on the functional area located in the vertical direction, and thus obtaining different rebound, cushioning and support characteristics at the sole position corresponding to the functional area in the vertical direction.

[0022] 2. By setting the number of functional areas with the same characteristics to two, and setting the two functional areas in a mirror image with the first axis as the axis of symmetry, the characteristic effect of the functional area is maximized when the functional area is switched to the vertical direction, thereby improving the accuracy of adjusting the rebound, cushioning and support performance of the sole.

[0023] 3. By setting limiting units on both sides of the adjustment unit, the adjustment unit is limited in the lateral direction in the heel area of ​​the sole, so that the adjustment module has high stability when rotating and under force. Attached Figure Description

[0032] To better understand the purpose, structure, and function of this utility model, the sole of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 8As shown, the side of the sole closest to the inside of the foot is defined as the inner side of the sole, the side closest to the outside of the foot is defined as the outer side of the sole, the end closest to the toe is defined as the front side of the sole, the end closest to the heel is defined as the back side of the sole, the side closest to the sole is defined as the top side of the sole, and the side furthest from the sole is defined as the bottom side of the sole. The line connecting the inner and outer sides is horizontal, the line connecting the front and back sides is vertical, and the line connecting the top and bottom sides is vertical.

[0034] The sole includes a forefoot area, a midfoot area, and a heel area connected in sequence. An adjustment unit is provided on at least one area. The adjustment unit includes an adjustment module and a first axis arranged laterally within the adjustment module. The adjustment module includes at least two functional areas with different characteristics. Each functional area of ​​the adjustment module includes several cushioning parts. By setting the cushioning parts in each functional area to different materials and / or different volume structures, each functional area has different rebound, cushioning, and support characteristics. In use, the functional areas are rotated to different angles around the first axis arranged laterally, so that the different functional areas switch positions in the vertical direction of the sole. This concentrates the pressure of the human foot on the functional areas located in the vertical direction, thereby obtaining different rebound, cushioning, and support characteristics at the sole positions corresponding to the functional areas in the vertical direction.

[0035] It should be noted that the sole has a multi-layered composite structure. The adjustment module is located between the upper and lower layers of the sole. The functional areas within the adjustment module can be rotated to be closer to the upper or lower layer in the vertical direction, thereby enabling more concentrated energy transfer. Specifically, this concentrates the pressure of the human foot onto the functional areas located in the vertical direction. In particular, the adjustment module in the vertical direction is located on the extension line of the vertical force exerted by the human body on the sole, which amplifies the effect of the functional areas in the vertical direction on the sole's rebound, cushioning, and support. Therefore, different functional areas can be switched to the vertical direction according to different ground conditions and individual gait characteristics, thereby helping to improve athletic performance and enhance overall wearing comfort.

[0036] Preferably, the number of functional areas with the same characteristics is set to two, and the two functional areas are set as mirror images with the first axis as the axis of symmetry. In this way, when the functional area is switched to the vertical direction, the characteristic effect of the functional area is maximized, that is, the interference of the characteristics of other functional areas on the characteristics of the functional area in the vertical direction is reduced, and the accuracy of adjusting the rebound, cushioning and support performance of the sole is improved.

[0037] Furthermore, by setting limiting units on the adjustment unit, clamping forces are formed on the inner and outer sides of the adjustment module, respectively, limiting its lateral movement at the corresponding position on the sole, thereby enhancing the stability of the adjustment module during rotation and under stress. Alternatively, the adjustment module can be configured as a columnar structure of varying diameters, snapped onto the corresponding position on the sole, thus achieving the same lateral limiting effect.

[0038] Specifically, the functional areas of the adjustment module can have different rebound, cushioning, and support characteristics. For example, the high rebound area is made of highly elastic materials or structures to provide maximum energy return; the high cushioning area is made of highly shock-absorbing materials or structures to reduce impact during exercise; and the high support area uses a reinforced structural design to provide additional foot support. By rotating the adjustment module, the functional areas are positioned at different angles, and the force exerted by the human foot on the sole is applied to the functional areas with different characteristics, allowing the human foot and its various parts to obtain the required rebound, cushioning, and support characteristics in different scenarios.

[0039] To better understand the purpose, structure, and function of this utility model, the following detailed description of the sole of this utility model will be provided with reference to the accompanying drawings, taking the specific structure of the sole as an example.

[0040] Example 1, as Figures 1 to 4 As shown, the sole includes a forefoot area, a midfoot area, and a heel area arranged longitudinally in sequence. An adjustment unit 100 is provided at the stress point of the heel area. The adjustment unit 100 includes an adjustment module 101, a first axis 102 arranged laterally, and a limiting unit. The first axis 102 is disposed within the adjustment module 101 so that the adjustment module 101 can rotate around the first axis 102. The limiting unit is disposed on both sides of the adjustment module 101 to fix the adjustment module laterally. The adjustment module 101 includes three functional areas with different characteristics: a first functional area 111, a second functional area 112, and a third functional area 113. When the adjustment module 101 rotates, the first functional area 111, the second functional area 112, and the third functional area 113 rotate to different angles relative to the heel area of ​​the sole, thereby creating different characteristics in the heel area of ​​the sole to meet the user's needs in different usage scenarios.

[0041] Specifically, a cross-section is defined as the section formed by cutting perpendicular to the axis of the columnar structure along the longitudinal direction. Therefore, in this embodiment, the adjustment module 101 is set as a columnar structure with a circular cross-section. It should be noted that the aforementioned circle includes both circles with equal radii at all points and regular polygons that are approximately circular, as long as they can achieve the effect of lateral rotation of the adjustment module 101 on the sole about the first axis 102. Only one adjustment module 101 is provided, and each of its two ends and middle positions has a cross-section with the same diameter to provide stable vertical support in the lateral direction.

[0042] like Figure 4 As shown, the limiting unit includes a first component 103 and a second component 104 disposed opposite to the adjustment module 101. The first component 103 and the second component 104 are plate-shaped structures, respectively disposed on the upper and lower sides of the adjustment module 101, and can limit it in the vertical direction. One end of the first component 103 located on the inner side of the sole body bends toward the second component 104, and one end of the second component 104 located on the inner side of the sole body bends toward the first component 103. Thus, the ends of the first component 103 and the second component 104 located on the inner side of the sole body are arranged close to each other. One end of the first component 103 located on the outer side of the sole body bends toward the second component 104, and one end of the second component 104 located on the outer side of the sole body bends toward the first component 103. Thus, the other ends of the first component 103 and the second component 104 located on the outer side of the sole body are also arranged close to each other. This forms a limiting effect on the adjustment module 101 in the lateral direction of the heel area of ​​the sole, thereby enhancing the stability of the adjustment module 101 when rotating and under force.

[0043] It is understandable that, in addition to setting the first component 103 and the second component 104 mentioned above, other limiting units can be set individually or simultaneously. For example, the sole also includes two frames (not shown in the figure). The two frames are respectively set on the inner outer wall and the outer outer wall of the heel area of ​​the sole, and are fixedly connected to one end of the first shaft 102 located on the inner side of the sole body and the other end located on the outer side of the sole body. This can also achieve the effect of forming clamping force on the inner and outer sides of the adjustment module 101 and improving stability.

[0044] like Figure 2 and Figure 3As shown, the first functional area 111, the second functional area 112, and the third functional area 113 of the adjustment module 101 are columnar structures with a fan-shaped cross-section. Two first functional areas 111 are arranged opposite each other with the first axis 102 as the axis of symmetry. Similarly, two second functional areas 112 are arranged opposite each other with the first axis 102 as the axis of symmetry, and two third functional areas 113 are arranged opposite each other with the first axis 102 as the axis of symmetry. Thus, the first functional areas 111, the second functional areas 112, and the third functional areas 113 are connected and arranged in sequence to form an adjustment module 101 with an overall cylindrical structure. Rotating the adjustment module 101 causes each functional area to be located at different angles, thereby changing the characteristics of the sole corresponding to the force-bearing part of the human heel.

[0045] The first functional area 111, the second functional area 112, and the third functional area 113 all include a support part 115 and several buffer parts 114 disposed inside the support part 115. The material strength of the support part 115 is greater than that of the buffer parts 114. On the one hand, the position of the buffer parts 114 is fixed by the support part 115, and on the other hand, the support part 115 provides basic support for the heel area of ​​the sole, so that the stress position of the heel can have stability and resilience.

[0046] The buffer sections 114 within the first functional area 111, the second functional area 112, and the third functional area 113 are columnar structures, each composed of different materials and having different volumes. In this embodiment, the diameter of the cross-section of the buffer sections 114 in each functional area is different, so that functional areas with different characteristics are formed on the adjustment module 101. In this embodiment, the buffer section 114 of the first functional area 111 is made of a highly elastic material, the buffer section 114 of the second functional area 112 is made of a material that efficiently absorbs shock, and the buffer section 114 of the third functional area 113 is made of a low-elasticity reinforcing material. Furthermore, the volumes of the buffer sections 114 in the three functional areas are different, resulting in the first functional area 111 having greater elasticity than the second functional area 112, and the second functional area 112 having greater elasticity than the third functional area 113. Consequently, the first functional area 111 can provide the maximum energy feedback, the second functional area 112 can reduce the impact force on the sole of the foot during exercise, and the third functional area 113 can provide additional support for the sole of the foot. The switching of these functional areas is achieved by rotating the adjustment module 101.

[0047] The support portions 115 of the first functional area 111, the second functional area 112, and the third functional area 113 are made of at least one of nylon, thermoplastic polyurethane, and foamed elastomer. The buffer portions 114 of the first functional area 111, the second functional area 112, and the third functional area 113 are internally filled with gas and / or polyurethane. The length-to-width ratio of the cross-section of the buffer portions 114 of the first functional area 111, the second functional area 112, and the third functional area 113 is 1:1, that is, the buffer portions 114 are all circular or regular polygonal columnar structures to ensure that the width and height of the buffer portions 114 remain consistent after rotation, the shape remains unchanged, and only the internal properties change.

[0048] It is understood that the buffer portions 114 of the first functional area 111, the second functional area 112, and the third functional area 113 in this embodiment are made of different materials and have different volume structures. Those skilled in the art can also make the buffer portions 114 of each functional area different only in terms of material or only in terms of volume structure, so as to achieve different technical effects of rebound, shock absorption and support in each functional area.

[0049] It should be noted that the adjustment module 101 in this embodiment has three functional areas with different characteristics, which can be set in the forefoot area, midfoot area, and heel area of ​​the sole. It can be adjusted to meet the different needs of the human forefoot, midfoot, and heel. Specifically, the human forefoot needs adjustable rebound and good cushioning, with a large compression stroke when walking and a small compression stroke when running; the heel needs adjustable cushioning, which can be enhanced to increase the compression stroke for comfort, and can be adjusted to provide high support and reduce the compression stroke when walking; the midfoot needs adjustable arch support. By setting the adjustment module 101 towards the medial side of the midfoot of the sole, the support strength at the medial arch can be adjusted. The above-mentioned technical effects can be achieved by adjusting the setting angle of the first functional area 111, the second functional area 112, and the third functional area 113 in this embodiment.

[0050] Furthermore, the external part of the adjustment unit 100 is provided with a cylindrical rotating groove (not shown in the figure). The adjustment unit 100 also includes a number of protruding ribs 116, which are spaced around the external part of the adjustment module 101 so that the adjustment unit 100 is engaged in the inner wall of the rotating groove to prevent the columnar adjustment unit 100 from rotating unnecessarily during the human body running. The width of the protruding ribs 116 gradually decreases in the outward direction to reduce the resistance generated when the adjustment unit 100 needs to be rotated.

[0051] In use, by rotating the first functional area 111, the second functional area 112, and the third functional area 113, the functional area corresponding to the desired effect is rotated to the vertical direction relative to the sole of the shoe. That is, the line connecting the functional areas is aligned with the direction of the force exerted by the human heel on the sole of the shoe, so as to maximize the characteristic effect of the functional area. Specifically, the user can use wireless control by mobile phone, sensor perception adaptive control, electric button active control, etc. to control the motor and gearbox inside the sole of the shoe, thereby realizing the rotation of the adjustment module 101.

[0052] Example 2 is the same as Example 1 in terms of the overall structure and location of the momentum transfer module. The difference lies in the specific structure of the adjustment module, such as... Figure 5 As shown, in this embodiment, two adjustment modules 200 of the same size are arranged opposite each other on the inner and outer sides of the sole, with a gap between the two adjustment modules 200. This ensures that the heel area of ​​the sole corresponding to the adjustment module 200 receives the same support in the lateral direction while reducing the cost of the adjustment modules. Of course, more adjustment modules of the same size can be used to achieve the same effect.

[0053] The following embodiments three, four, and five are the same as embodiment one in terms of the overall structure and placement of the momentum transfer module. The difference lies in the specific structure of the adjustment module. The diameter of the cross-section of the adjustment module is a non-equidistant structure so that the adjustment module can be fitted into the midsole structure of the shoe sole in the vertical direction. In this way, the midsole structure of the shoe sole limits the adjustment module in the horizontal direction, thereby enhancing the stability of the adjustment module when rotating and under stress. In other words, even if the limiting unit is not set in embodiments three, four, and five, its stability on the shoe sole can still be maintained.

[0054] Example 3, as Figure 6 As shown, the adjustment module 300 includes a first part 301 located on the inner side of the sole, a third part 303 located on the outer side of the sole, and a second part 302 connecting the first part 301 and the third part 303. The diameters of the first part 301 and the third part 303 are both of a first length, and the diameter of the second part 302 is a second length. The second length is slightly smaller than the first length, and the first length and the second length are connected by a linear transition. The adjustment module 300 as a whole has a peanut-shaped structure that is thick at both ends and thin in the middle. This peanut-shaped structure can more naturally conform to the shape of the heel. Especially under load, the pressure of the heel will be more evenly distributed on the sole, reducing local high pressure points and reducing discomfort caused by long-term walking or exercise.

[0055] Example 4, as Figure 7As shown, the adjustment module 400 includes a first part 401 located on the inner side of the sole, a third part 403 located on the outer side of the sole, and a second part 402 connecting the first part 401 and the third part 403. The diameters of the first part 401 and the third part 403 are both of a first length, and the diameter of the second part 402 is a second length, which is smaller than the first length. The first length and the second length are connected by a non-linear transition. The adjustment module 400 has a dumbbell-shaped structure that is thicker at both ends and thinner in the middle. This dumbbell-shaped structure can provide better lateral stability because the larger ends can better distribute pressure and help prevent the foot from slipping inside the shoe, providing athletes or walkers with an extra sense of security.

[0056] Example 5, as Figure 8 As shown, the adjustment module 500 includes a first part 501 located on the inner side of the sole, a third part 503 located on the outer side of the sole, and a second part 502 connecting the first part 501 and the third part 503. The diameters of the first part 501 and the third part 503 are both of a first length, while the diameter of the second part 502 is of a second length. The first length is shorter than the second length, and the connection between the first and second lengths is a linear transition. The adjustment module 500 as a whole has a spindle-shaped structure that is thinner at both ends and thicker in the middle. This spindle-shaped structure enhances the flexibility and responsiveness of the sole in all directions, allowing the heel to roll more naturally during movement. This is particularly advantageous for running or other sports that require rapid changes of direction, as it reduces energy loss, improves efficiency, and provides the wearer with a propulsive force.

[0057] This utility model also provides a shoe, including an upper and the sole described above.

[0058] The sole of this invention has the following advantages:

[0059] 1. By setting an adjustment unit on the sole, the adjustment module in the adjustment unit includes at least two functional areas with different characteristics. When in use, the functional areas are rotated to different angles around the first axis set horizontally, so that the different functional areas switch positions in the vertical direction of the sole, thereby concentrating the pressure of the human foot on the functional area located in the vertical direction, and thus obtaining different rebound, cushioning and support characteristics at the sole position corresponding to the functional area in the vertical direction.

[0060] 2. By setting the number of functional areas with the same characteristics to two, and setting the two functional areas in a mirror image with the first axis as the axis of symmetry, the characteristic effect of the functional area is maximized when the functional area is switched to the vertical direction, thereby improving the accuracy of adjusting the rebound, cushioning and support performance of the sole.

[0061] 3. By setting limiting units on both sides of the adjustment unit, the adjustment unit is limited in the lateral direction in the heel area of ​​the sole, so that the adjustment module has high stability when rotating and under force.

[0062] The terms “above,” “below,” and “within” as used above include the number itself; the terms “exceeding” and “excluding” do not include the number itself.
