Description

Technical Field

[0001] This invention relates to the field of shoe sole technology, specifically to a high-resilience shoe sole and shoe. Background Technology

[0002] For walking or exercise, shoes need soles that provide support to maintain balance and stability, offer cushioning to reduce impact and injury, and provide good energy return for effortless walking and exercise. However, providing support requires a certain degree of rigidity, while cushioning requires elasticity to absorb impact and vibration. This absorption can, in turn, affect energy return. Therefore, it's difficult for existing shoe soles to excel in all three aspects simultaneously. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a high-resilience sole and shoe that can provide better support, cushioning and energy feedback for the human body, so as to achieve a stable and effortless wearing experience.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-resilience sole includes: a support member having a support bottom plate, a support top plate, and an elastic bending portion; the support bottom plate extends from the heel to the forefoot corresponding to the sole; the support top plate is located at the heel and above the support bottom plate corresponding to the sole; the elastic bending portion corresponds to the rear end of the sole and connects the support bottom plate and the support top plate; and a midsole, the bottom surface of which abuts against the top surface of the support bottom plate, the top surface corresponding to the heel of the sole abuts against the bottom surface of the support top plate, and the rear end of which forms a clearance space with the support member.

[0006] Furthermore, the rear end of the midsole is located near the elastic bending portion at the middle position relative to the heel of the sole.

[0007] Furthermore, a supporting sidewall extends upward from the periphery of the supporting top plate.

[0008] Furthermore, the supporting top plate is provided with a plurality of weight-reducing holes that extend through the vertical direction.

[0009] Furthermore, the support member is a carbon fiber plate, a nylon plate, or a TPU plate.

[0010] Furthermore, it also includes a sole, which is attached to the bottom surface of the supporting base plate.

[0011] In addition, the present invention also provides a shoe, including an upper and a high-resilience sole as described in any of the preceding claims, the upper being attached to the high-resilience sole.

[0012] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The high-resilience sole provided by this invention includes a support member and a midsole. Generally, the midsole has a certain elasticity, which can provide users with a good wearing comfort, and at the same time, it can provide a certain rebound performance for users' movements through deformation. In this sole, the midsole is placed on the support member, which has a support bottom plate and a support top plate. The support bottom plate extends from the heel to the forefoot, and can be regarded as the support bottom plate corresponding to the entire sole. The entire midsole is placed on the top surface of the support bottom plate. The support top plate is located above the support bottom plate and is set at the heel of the sole. The support bottom plate and the support top plate are connected by an elastic bending part. When the support top plate moves downward under the pressure of the heel, The elastic bending section is involved, causing it to deform. This deformation quickly recovers when the pressure on the heel decreases, thus driving the support plate back to its original position. This process allows the support component to provide the user with better rebound performance. The midsole is located between the support plate and the support top plate, and a clearance space is formed between the rear end of the midsole and the support component. When the support top plate is pressed down, the midsole will deform under the pressure of the support top plate. At this time, the rear end of the midsole will protrude a certain distance. The clearance space can provide for the rear end of the midsole to protrude, which can prevent the support component from restricting the deformation of the midsole. After the midsole has fully deformed, it can provide better rebound performance when it recovers its deformation.

[0014] Meanwhile, since the support plate of the support component corresponds to the bottom of the entire sole, and the midsole is located above the support plate of the support component, the contact between the support component and the ground no longer needs to be separated by a soft midsole. When the support plate is subjected to pressure, this pressure can be quickly transmitted to the support plate through the elastic bending part. The support plate can expand the contact area of ​​the force and reduce the pressure, so that when the user's heel applies force to the support plate, it can obtain a lighter and more obvious feeling of stepping on the ground, giving the user better support and achieving the performance goal of good performance in support, cushioning and energy return.

[0015] 2. By placing the rear end of the midsole closer to the elastic flex point, when the user applies force to the support plate, the main point of force is in the middle of the support plate, which is the middle of the heel. At this time, the support plate will better transfer the force to the midsole. However, at the same time, the rear end of the midsole is a certain distance from the elastic flex point. This allows the midsole to release this deformation by making room when it is subjected to a large force and tends to deform, thereby effectively improving the rebound performance and support performance of the sole.

[0016] 3. Supporting sidewalls are installed on the top support plate to provide lateral support to the user's heel when wearing the shoes, making the sole fit better and preventing the user from twisting their ankle.

[0017] 4. Weight reduction holes are set on the top support plate. These holes can reduce the weight of the support components, thereby reducing the weight of the sole.

[0018] 5. The support components are made of carbon fiber plates, nylon plates, or TPU plates, which can provide good support, shock absorption, and energy feedback through their own material properties.

[0019] 6. The sole also includes an outsole, which is attached to the bottom of the supporting plate and provides wear resistance and slip resistance to the sole.

[0020] 7. The shoes provided by the present invention use a high-resilience sole as described above, which can provide better support, shock absorption and energy feedback for the human body, so as to achieve a stable and effortless wearing experience. Attached Figure Description

[0035] Example 1

[0036] This invention provides a shoe sole, which can be referred to in the embodiments described herein. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The sole includes a support component 10, a midsole 20, and an outsole 40.

[0037] The support member 10 includes a support base plate 11, a support top plate 13, and an elastic bending part 12. The support base plate 11 corresponds to the sole extending from the heel to the forefoot. The support top plate 13 corresponds to the sole located at the heel and above the support base plate 11. The elastic bending part 12 corresponds to the rear end of the sole and connects the support base plate 11 and the support top plate 13. The midsole 20 has its bottom surface abutting against the top surface of the support base plate 11, and its top surface at the heel of the sole abutting against the bottom surface of the support top plate 13. A clearance space 30 is formed between its rear end and the support member 10.

[0038] It should be noted that the above-mentioned sole has parts corresponding to the human foot. The names of these parts and the spatial portions they refer to are well known to those skilled in the art. For example, the forefoot of the above-mentioned sole refers to the part corresponding to the front end of the human foot to the arch, and the heel refers to the part corresponding to the arch to the back end of the human foot. In other applications, the arch may be divided separately, but in this embodiment, the sole is only divided into the forefoot and the arch. Therefore, the scope referred to by the forefoot should include part of the arch.

[0039] Reference Figure 1 and Figure 2The support member 10 is a one-piece molded component, and its material can be carbon fiber, nylon, or TPU. In this embodiment, carbon fiber is selected. Taking the direction shown in the figure as an example, the support base plate 11 of the support member 10 is located below, and the support top plate 13 is located above the support base plate 11. At the same time, the support base plate 11 corresponds to the shape of the sole, extending from the heel to the forefoot. This can be regarded as the support base plate 11 corresponding to the shape of the entire sole. Thus, the midsole 20 can be fixed to the top surface of the support base plate 11 by adhesive or other means. The midsole 20 is in complete contact with the ground through the support base plate 11. In this embodiment, referring to the figure, an outsole 40 is also attached below the support base plate 11. The outsole 40 is usually made of vulcanized rubber. The support base plate 11 is in contact with the ground through the outsole 40, which can prevent the support base plate 11 from being worn. The midsole 20 can be made of EVA foam or other midsole materials, as long as it can provide a certain rebound performance. However, it should be noted that in this embodiment, the midsole 20 is completely placed on the support member 10, and the bottom surface of the support member 10 is completely in contact with the outsole 40. Therefore, the support member 10 forms a partition between the midsole 20 and the outsole 40.

[0040] An elastic bending portion 12 is formed at the rear end of the support member 10. The lower side of the elastic bending portion 12 is connected to the support base plate 11, and the upper side is connected to the support top plate 13. The elastic bending portion 12 itself forms a structure that first protrudes backward from bottom to top and then bends forward. The elastic bending portion 12 cooperates with the support base plate 11 and the support top plate 13. When the support top plate 13 is subjected to downward pressure, the elastic bending portion 12 will deform, thereby allowing the support top plate 13 to move downward. At this time, the deformation is mainly concentrated in the elastic bending portion 12.

[0041] The supporting top plate 13 is positioned at the heel of the shoe sole, serving to support the user's heel. A leading edge 132 is formed at the front end of the supporting top plate 13, which roughly corresponds to the junction between the heel and forefoot of the shoe sole. Supporting sidewalls 14 are also provided around the periphery of the supporting top plate 13, extending upwards from the supporting top plate 13, providing lateral support for the user's heel.

[0042] For the support member 10, there are slight differences in the rigidity of different parts. In this embodiment, the support base plate 11 and the support top plate 13 have higher rigidity, while the elastic bending part 12 has better elasticity. When carbon fiber is used as the manufacturing material, the rigidity of different positions can be adjusted by adjusting the direction of the carbon fiber.

[0043] Reference Figure 5The midsole 20 includes a forefoot and a heel, corresponding to the forefoot and heel of the sole, respectively. A contact surface 222 is formed at the top of the heel, and a connecting surface 211 is formed between the contact surface 222 and the forefoot of the midsole 20. This connecting surface 211 extends upwards from the contact surface 222, forming a stepped structure. When the midsole 20 is fixed to the support member 10, the bottom surface of the midsole 20 contacts the top surface of the support plate 11, while the contact surface 222 at the heel of the midsole 20 contacts the bottom surface of the support top plate 13. The leading edge 132 of the top plate 13 abuts against the connecting surface 211, and the top surface of the forefoot of the midsole 20 can directly contact the forefoot portion of the user's foot, creating a soft forefoot support and a hard heel support effect.

[0044] In this embodiment, after the midsole 20 is installed onto the support member 10, a clearance space 30 is formed between the rear end of the midsole 20 and the elastic bending portion 12 on the support member 10, so as to... Figure 1 Taking the direction shown as an example, the rear side of this clearance space 30 is the elastic bending part 12, the front side is the rear end of the midsole 20, the upper side is the bottom surface of the supporting top plate 13, and the lower side is the top surface of the supporting bottom plate 11. Furthermore, this clearance space 30 is open on both sides of the sole. This structure allows the supporting top plate 13 to exert pressure on the midsole 20 when it is pressed down, causing the midsole 20 to deform rapidly. The rear end of the midsole 20 will protrude towards the elastic bending part 12. At this time, the clearance space 30 serves to allow the rear end of the midsole 20 to protrude, which can prevent the supporting member 10 from restricting the deformation of the rear end of the midsole 20. At the same time, the midsole 20 will also have some slight deformation on both sides of the sole. The open structure on both sides of the clearance space 30 also allows the midsole 20 to protrude freely on these sides.

[0045] Specifically, the rear end of the midsole 20 is located near the elastic bending portion 12 at the middle position relative to the heel of the sole. That is, the rear end of the midsole 20 extends rearward to a position relatively close to the elastic bending portion 12. The contact surface 222 of the midsole 20 can cover the support plate 13. This allows the support plate 13 of the support member 10 to transfer most of the force to the midsole 20 when it is under force. The midsole 20 can also receive the force transmitted by the support plate 13 well. The deformation of the midsole 20 can be more rapid. This allows the midsole 20 to release this deformation through the clearance space 30 when it tends to deform under a large force, thereby effectively improving the rebound performance and support performance of the sole.

[0046] To further illustrate the rebound and cushioning performance of the sole provided in this embodiment, an impact simulation experiment was conducted on the sole. Conventional EVA material was used as the midsole 20, and carbon fiber material was used as the support component 10. A steel ball of constant mass impacted the heel of the sole. The initial velocity of the steel ball was 2.2 m / s, and the rebound velocity after impact was 2.12 m / s. The peak impact force was approximately 1051.2 N, the steel ball displacement was 10 mm, and the contact time was approximately 0.015 s. The resulting DSI was 95.5 N / m. These values ​​indicate that the sole has good rebound performance and can provide good support for the user.

[0047] The high-resilience sole provided in this embodiment includes a support member 10 and a midsole 20. Generally, the midsole 20 has a certain degree of elasticity, which can provide users with a good wearing comfort, and at the same time, it can provide a certain degree of rebound performance for users' movements through deformation. In this sole, the midsole 20 is placed on the support member 10. The support member 10 has a support bottom plate 11 and a support top plate 13. The support bottom plate 11 extends from the heel of the sole to the forefoot, and can be regarded as the support bottom plate 11 corresponding to the entire sole. The midsole 20 is placed on the top surface of the support bottom plate 11. The support top plate 13 is located above the support bottom plate 11. Furthermore, corresponding to the heel of the shoe sole, the support base plate 11 and the support top plate 13 are connected by an elastic bending portion 12. When the support top plate 13 moves downward under the pressure of the heel, the elastic bending portion 12 is pulled along, causing it to deform. The deformation of the elastic bending portion 12 will quickly recover when the pressure on the heel decreases, thereby driving the support top plate 13 to return to its position. This process enables the support member 10 to provide the user with better rebound performance. The midsole 20 is located between the support base plate 11 and the support top plate 13, and a clearance space is formed between the rear end of the midsole 20 and the support member 10.

[0048] 30. When the supporting top plate 13 is pressed down, the midsole 20 will deform under the pressure of the supporting top plate 13. At this time, the rear end of the midsole 20 will protrude a certain distance, and the space 30 can serve to allow the rear end of the midsole 20 to protrude, which can prevent the supporting member 10 from restricting the deformation of the midsole 20. After the midsole 20 has fully deformed, it can provide better rebound performance when it recovers its deformation. At the same time, since the supporting bottom plate 11 of the supporting member 10 corresponds to the bottom of the entire sole, and the midsole 20 is located above the supporting bottom plate 11 of the supporting member 10, The support member 10 no longer needs a soft midsole 20 to contact the ground. When the support top plate 13 is under pressure, this pressure can be quickly transmitted to the support bottom plate 11 through the elastic bending part 12. The support bottom plate 11 can expand the contact area 222 of the force and reduce the pressure, so that when the user's heel applies force to the support top plate 13, it can obtain a lighter and more obvious feeling of stepping on the ground, giving the user better support and achieving the performance goal of good support effect, shock absorption effect and energy return effect.

[0049] Example 2

[0050] The specification of this invention also provides an embodiment 2, which differs from embodiment 1 in that the structure of the support member 10 is improved, as detailed below. Figure 3 Several weight-reducing holes 131 are provided on the top support plate 13, which run through the vertical direction. These weight-reducing holes 131 can reduce the weight of the support member 10 without reducing the structural strength of the top support plate 13.

[0051] Example 3

[0052] The specification of this invention also provides Embodiment 3, which provides a shoe that includes an upper and a high-resilience sole provided in Embodiment 1 or Embodiment 2. The upper is fixed to the high-resilience sole by means of adhesive or other methods, which can provide good support, shock absorption and energy feedback for the human body, so as to achieve a stable and effortless wearing experience.
