Description

Technical Field

[0001] This invention belongs to the field of footwear, and particularly relates to a sole and a shoe. Background Technology

[0002] Shoes, as an indispensable part of daily life, were originally designed to protect the feet from external environmental damage and ensure safety while walking. However, with the rapid development of living standards, people have increasingly higher demands for shoes, with some offering breathability and dryness, others warmth, slip resistance, and shock absorption.

[0003] Studies have shown that for every kilometer a person walks, one foot experiences 600-700 impacts from gravity. During strenuous exercise, the impact is even greater. When running, the impact force of the foot striking the ground can reach 2-4 times the body weight. This impact generates shockwaves within the body, causing varying degrees of damage to different parts. This necessitates that shoe soles possess the ability to absorb and reduce the impact force from the ground, i.e., shock absorption and cushioning performance.

[0004] Most existing shoe soles rely on the selection of midsole materials to achieve better shock absorption performance. Generally, the shock absorption effect is achieved through the vertical compression and release characteristics of the midsole material itself. This shock absorption structure cannot effectively distribute the impact force and has poor shock absorption effect, which can easily cause sports injuries. Summary of the Invention

[0005] The purpose of this invention is to provide a shoe sole and shoe that, through the cooperation of the first locking part and the second locking part, increases the distance of the force application, reduces the occurrence of sports injuries, and has a good shock absorption effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The present invention provides a shoe sole, comprising a shoe sole body, a support plate, and a support body. The shoe sole body has at least one support body. The support plate is connected to the shoe sole body and / or the upper surface. The support plate has at least one first locking portion. The support body has at least one second locking portion. The first locking portion and the second locking portion engage, and there is a moving space between the first locking portion and the second locking portion. The support body is distributed at least at one location in the periphery of the shoe sole body, the forefoot area, and the heel area.

[0008] Preferably, the first locking part and / or the second locking part are elastic, so that the first locking part can disengage from the second locking part under the action of external force, and the first locking part and the second locking part can be reset and engaged when the external force is removed.

[0009] Preferably, the first locking part is located on the side of the support piece close to the support body, and the first locking part has a first locking groove. The end of the support body close to the support piece is the second locking part, which is locked into the first locking groove and can move horizontally relative to the first locking groove.

[0010] Preferably, the first locking part is located on the side of the support piece close to the support body, and the end of the support body close to the support piece is the second locking part. The second locking part has a second locking groove, the first locking part is locked into the second locking groove, and can move horizontally relative to the second locking groove.

[0011] Preferably, the first locking part is located on the side of the support piece close to the support body, the first locking part has a third locking groove, the end of the support body close to the support piece has a second locking part, the second locking part is locked into the third locking groove, and can move vertically relative to the third locking groove.

[0012] Preferably, the first locking part is located on the side of the support piece close to the support body, and the end of the support body close to the support piece is the second locking part. The second locking part has a fourth locking groove, the first locking part is locked into the fourth locking groove, and can move vertically relative to the fourth locking groove.

[0013] Preferably, when there are two or more supports, adjacent supports are spaced apart.

[0014] Preferably, the support body is distributed in the forefoot area and / or heel area of ​​the sole body, and the support body includes multiple support groups spaced apart along the length direction of the sole body, and each support group includes several support bodies spaced apart along the width direction of the sole body.

[0015] Preferably, the sole body has at least one deformation space, and the support body and the deformation space are distributed adjacent to each other.

[0016] Preferably, the support piece is disposed opposite to at least one support body.

[0017] Preferably, the support piece extends to the sidewall of the sole body or extends through the sidewall of the sole body to the upper surface.

[0018] Preferably, when there are multiple first card parts, there is a gap between adjacent first card parts; when there are multiple second card parts, there is a gap between adjacent second card parts.

[0019] Preferably, the sole body includes a midsole and / or an outsole. When the sole body is a midsole, the support body is located on the side of the midsole closest to the human foot, and the support plate is connected to the upper. When the sole body is an outsole, the support body is located on the side of the outsole closest to the human foot, and the support plate is connected to the upper. When the sole body includes a midsole and an outsole, the midsole and the outsole are connected, the support body is located on the side of the outsole closest to the midsole, and the support plate is at least connected to the midsole. Alternatively, the midsole and the outsole are connected, the support body is located on the side of the midsole closest to the human foot, and the support plate is connected to the upper.

[0020] Preferably, the support body and the sole body are integrally formed.

[0021] Preferably, the support sheet is a foamed sheet, a rubber elastic sheet, or a carbon plate.

[0022] The present invention also provides a shoe, including the aforementioned sole.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. During exercise, the first and second locking sections move relative to each other, increasing the distance of force application and reducing the force on the sole. This reduces the shear force generated at the ankle and knee joints in the horizontal direction and / or the compressive force generated at the ankle and knee joints in the vertical direction, thus reducing the occurrence of sports injuries and providing good shock absorption. Because the first and / or second locking sections are elastic, when the force on the sole reaches a certain level, the first and second locking sections will disengage, causing them to tilt and further absorb force. Under different stress conditions, it can effectively absorb horizontal forces.

[0025] 2. The support plates can evenly distribute the force on the sole of the foot, enhance the stability of the support, and prevent tipping over.

[0026] 3. Through the spaced arrangement of multiple support elements, adjacent support elements have room to tilt outwards. During exercise, when the outsole of the shoe is subjected to force, the support elements tilt outwards in the direction of the force. On the one hand, the passive compression deformation of the support elements absorbs the impact force from the ground, achieving a cushioning and shock absorption effect; on the other hand, the tilt of the support elements in the direction of the force avoids friction between the sole and the insole caused by the impact force, reducing the occurrence of sports injuries such as blisters.

[0027] 4. Through the combination of the sole and the support structure, not only can the sole itself be compressed and released vertically, but the support structure can also deform and cushion laterally, effectively distributing the impact force evenly.

[0028] 5. Using supports in areas of concentrated stress can better concentrate the absorption of force and provide better shock absorption.

[0029] 6. By setting up the deformation space, the support can be placed inside the outsole or midsole of the shoe, and the support can also have space to tilt towards the surrounding deformation space. Attached Figure Description

Detailed Implementation

[0053] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0054] Contents not described in detail in this specification are prior art known to those skilled in the art. In the description of this invention, it should be understood that terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0055] Example 1:

[0056] like Figures 1 to 4 As shown in the figure, the shoe sole provided in this embodiment includes a shoe sole body 1, a support piece 2, and a support body 3.

[0057] In this embodiment, the sole body 1 is the outsole 12. In other embodiments, the sole body 1 can also be the midsole 11. The forefoot area of ​​the outsole 12 has multiple support bodies 3. In other embodiments, the support bodies 3 can also be distributed in the heel area, or both the forefoot and heel areas can have support bodies 3. The multiple support bodies 3 are integrally formed on the top of the outsole 12, and the support bodies 3 are elastic. Alternatively, in other embodiments, the support bodies 3 can be retrofitted onto the outsole 12. In this embodiment, the front and rear side walls of the support piece 2 extend upwards to be fixedly connected to the inner side of the upper, and are located above the support bodies 3 and the outsole 12. The bottom of the support piece 2 has multiple first locking portions 4 arranged vertically opposite to the support bodies 3. The bottom of each first locking portion 4 has a first locking groove 41, and the upper end of the support body 3 has a second locking portion 5. The second locking part 5 engages with the first locking groove 41, and there is a space for movement between the second locking part 5 and the first locking groove 41, allowing the second locking part 5 to move horizontally relative to the first locking groove 41. During movement, the first locking part 4 and the second locking part 5 move relative to each other, increasing the distance of the force application and reducing the horizontal force on the sole, thereby reducing the shear force generated at the ankle and knee joints and reducing the occurrence of sports injuries.

[0058] By setting the support plate 2, the force on the sole of the foot can be evenly distributed, enhancing the support stability and preventing rollover.

[0059] The multiple support bodies 3 include multiple sets of support groups spaced apart along the length of the sole body 1, and each support group includes several support bodies 3 spaced apart along the width of the sole body 1. Through the spacing of the multiple support bodies 3, there is space between adjacent support bodies 3 for them to tilt outwards. During exercise, when the outsole 12 is subjected to force, the support bodies 3 are impacted and tilt outwards in the direction of the force. On the one hand, the passive compression deformation of the support bodies 3 absorbs the impact force from the ground, achieving a cushioning and shock absorption effect; on the other hand, the tilting of the support bodies 3 in the direction of the force prevents friction between the foot and the insole caused by the impact force, reducing the occurrence of sports injuries such as blisters. In this embodiment, the outsole 12 is made of rubber material, which not only allows for vertical compression and release, but also, through the arrangement of the support bodies 3, allows for lateral deformation and cushioning, effectively distributing the impact force evenly.

[0060] By placing support bodies 3 in the forefoot and / or heel areas, the forefoot area experiences the most force during exercise, followed by the heel area. Placing support bodies 3 in these two locations can better concentrate the force absorption and provide better shock absorption.

[0061] When there are multiple first card parts 4, there is a gap 9 between adjacent first card parts 4; when there are multiple second card parts 5, there is a gap 9 between adjacent second card parts 5. The gap 9 allows for a space for adjacent first card parts 4 and adjacent second card parts 5 to tilt towards the periphery, preventing adjacent first card parts 4 or adjacent second card parts 5 from colliding and affecting the shock absorption effect.

[0062] In this embodiment, the second locking part 5 is elastic, allowing the first locking part 4 to disengage from the second locking part 5 under external force, and the first locking part 4 and the second locking part 5 to re-engage when the external force is removed. When the horizontal force on the sole is insufficient, the second locking part 5 slides within the first locking groove 41, reducing the horizontal force on the sole by increasing the distance of the applied force. When the horizontal force on the sole is large enough, the second locking part 5 deforms and disengages from the first locking groove 41, tilting to absorb the horizontal force. Under different stress conditions, it can effectively absorb horizontal forces, thereby reducing the shear force generated at the ankle and knee joints and reducing the occurrence of sports injuries.

[0063] This embodiment also provides a shoe, including the sole described above.

[0064] Example 2:

[0065] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that:

[0066] The support bodies 3 are distributed around the perimeter of the outsole 12, providing overall support and shock absorption for the outsole 12. Adjacent support bodies 3 are spaced apart.

[0067] Example 3:

[0068] like Figures 6 to 7 As shown, the difference between this embodiment and Embodiment 1 is that:

[0069] The top of the outsole 12 has multiple deformation spaces 7, which are cut directly from the top of the outsole 12. The support body 3 and the deformation spaces 7 are distributed adjacent to each other. The setting of the deformation spaces 7 allows the support body 3 to tilt towards the surrounding deformation spaces 7. When the outsole 12 is subjected to force during exercise, the support body 3 is subjected to impact force and tilts towards the surrounding deformation spaces 7 in the direction of the force. The deformation of the support body 3 can absorb the horizontal force, thereby reducing the shear force generated by the horizontal force at the ankle and knee joints and reducing the occurrence of sports injuries.

[0070] The support piece 2 is attached to the top surface of the outsole, and its front and rear side walls extend to the inner wall of the side wall 8 of the outsole 12, and then extend through the side wall 8 of the outsole 11 to the upper surface, where it is fixedly connected. The support body is placed within the deformation space, allowing the support piece to fit against the top surface of the outsole, and subsequently, a portion of the support piece to fit against the side wall of the outsole, and then connect to the upper surface, thus improving the connection stability of the support piece.

[0071] Example 4:

[0072] like Figures 8 to 11 As shown, the difference between this embodiment and Embodiment 1 is that:

[0073] The shoe sole body 1 includes a midsole 11 and an outsole 12. The midsole 11 is connected to the outsole 12 and is located above the outsole 12. A support body 3 is disposed on the upper side of the outsole 12, and the top surface of the support piece 2 is fixedly connected to the midsole 11. That is, the support piece 2 is disposed between the midsole 11 and the outsole 12. In this embodiment, the midsole 11 is made of foam material.

[0074] Each support group includes only one support body 3 extending along the width direction of the sole body 1, and each support body 3 has a corresponding support piece 2 on top. The bottom of each support piece 2 has a first locking part 4 that is vertically opposite to the support body 3.

[0075] Example 5:

[0076] like Figure 12 As shown, the difference between this embodiment and Embodiment 4 is that:

[0077] The midsole 11 is located above the outsole 12, and the support body 3 is located on the upper side of the midsole 11. The support piece is a one-piece design.

[0078] Example 6:

[0079] like Figures 13 to 15 As shown, the difference between this embodiment and Embodiment 4 is that:

[0080] The first locking part 4 is located on the lower side of the support piece 2, and the upper end of the support body 3 is the second locking part 5. The top of the second locking part 5 has a second locking groove 51. The first locking part 4 is inserted into the second locking groove 51 and can move horizontally relative to the second locking groove 51. The first locking part 4 is elastic and deforms more easily than the support body 3. When the horizontal force on the sole is not large enough, the first locking part 4 slides in the second locking groove 51, reducing the horizontal force on the sole by increasing the distance of the force application. When the horizontal force on the sole is large enough, the first locking part 4 deforms and disengages from the second locking groove 51, tilting to absorb the horizontal force.

[0081] The midsole 11 is connected to the outsole 12. The support body 3 is located on the upper side of the outsole 12. The left side of the support piece 2 is fixedly connected to the right side of the midsole 11. The right side of the support piece abuts against the outsole. There is only one support piece, which covers all the support bodies.

[0082] Example 7:

[0083] like Figures 16 to 18 As shown, the difference between this embodiment and Embodiment 5 is that:

[0084] The first locking part 4 is located on the lower side of the support piece 2, and the support body 3 is provided with first locking parts 4 on both the left and right sides. The inner side wall of the first locking part 4 has a third locking groove 42. The upper end of the support body 3 has second locking parts 5 on both the left and right sides. The second locking parts 5 are locked into the third locking groove 42 and can move vertically relative to the third locking groove 42. The second locking parts 5 are integrally formed with the support body 3 and are elastic. When the vertical force on the sole is not large enough, the second locking parts 5 slide in the third locking groove 42, increasing the distance of the force to reduce the vertical force on the sole, thereby reducing the compressive force generated at the ankle and knee joints, reducing the occurrence of sports injuries, and improving the shock absorption effect of the sole. When the vertical force on the sole is large enough, the second locking parts 5 will deform and detach from the third locking groove 42, and the second locking parts 5 will tilt to absorb the vertical force. Under different stress conditions, it can effectively absorb the vertical force and reduce the occurrence of sports injuries.

[0085] Both the support body and the support plate are located in the heel area. The midsole 11 is connected to the outsole 12. The support body 3 is located on the upper side of the outsole 12. The right side of the support plate 2 is fixedly connected to the left side of the midsole 11. The left side of the support plate rests against the outsole.

[0086] Example 8:

[0087] like Figures 19 to 20 As shown, the difference between this embodiment and Embodiment 1 is that:

[0088] The first locking part 4 is located on the lower side of the support piece 2, and the support body 3 is provided with first locking parts 4 on both the left and right sides. The upper end of the support body 3 is the second locking part 5, and the left and right sides of the second locking part 5 are provided with fourth locking grooves 52. The first locking part 4 is locked into the fourth locking groove 52 and can move vertically relative to the fourth locking groove 52. The first locking part 4 is L-shaped, elastic, and more prone to deformation than the support body 3. When the vertical force on the sole is not large enough, the first locking part 4 slides in the fourth locking groove 52, increasing the distance of the force to reduce the vertical force on the sole, further improving the shock absorption effect of the sole. When the vertical force on the sole is large enough, the first locking part 4 will deform and disengage from the fourth locking groove 52, and the first locking part 4 will tilt to absorb the vertical force.

[0089] Example 9:

[0090] like Figures 21 to 22 As shown, the difference between this embodiment and Embodiment 1 is that:

[0091] Part of the first locking part 4 and the second locking part 5 adopt the locking method of the first locking part and the second locking part in Embodiment 8. This can increase the distance of the horizontal and vertical forces, while reducing the shear force generated by the horizontal force at the ankle and knee joints and reducing the compressive force generated by the vertical force at the ankle and knee joints, thereby reducing the occurrence of sports injuries and providing good shock absorption.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
