Description

Technical Field

[0001] This application relates to the field of shoe sole technology, and in particular to a cushioned athletic shoe sole. Background Technology

[0002] Sports shoes have become an essential piece of equipment for people to exercise and walk leisurely in their daily lives. One of their core functions is cushioning and rebound, which effectively absorbs the impact force generated when the feet come into contact with the ground during exercise, so as to reduce fatigue and reduce the risk of sports injuries.

[0003] Chinese patent CN220571651U discloses a cushioned sports shoe sole and sports shoe, including a midsole and a wear-resistant layer fixed below the midsole. The rear of the midsole is provided with an upwardly protruding wrapping part, which wraps and supports the heel. A support member is attached and fixed behind the wrapping part, and the bottom of the support member is fixed to the midsole. The wrapping part is located behind the heel and fits against the heel.

[0004] The aforementioned athletic shoe soles offer good cushioning and protection, but they still have the following drawbacks: they cannot be personalized according to the athlete's weight, exercise intensity, or different sports scenarios, which is detrimental to athletic performance. Utility Model Content

[0005] To adapt to different usage scenarios, this application provides a shock-absorbing sports shoe sole.

[0006] The shock-absorbing sports shoe sole provided in this application adopts the following technical solution: A cushioning sports shoe sole includes an outsole and a midsole connected to the top of the outsole. A support block is detachably connected between the midsole and the outsole at the heel. A cushioning hole is provided in the middle of the support block. A fastening groove is provided at the bottom of the outsole. A countersunk groove is provided in the top wall of the fastening groove. A fixing rod is threaded through and threaded to the top wall of the countersunk groove. A fixing groove is provided in the support block for threaded connection of one end of the fixing rod.

[0007] By adopting the above technical solution, the support blocks can be replaced and tightened. Users can change the support blocks with different sizes and shapes of cushioning holes according to different sports scenarios (such as racing, training, and recovery), thereby customizing the cushioning firmness and rebound feedback of the heel, resulting in better practicality. Furthermore, simply changing the support blocks can provide different cushioning firmness, eliminating the need for users to buy different running shoes for different usage scenarios, thus improving cost-effectiveness.

[0008] Optionally, a guide post is connected to the bottom wall at the heel of the middle base, and a guide groove is provided on the top of the support block for the guide post to be inserted.

[0009] By adopting the above technical solution, the guide column and guide groove can facilitate the positioning and insertion of the support block during installation, thereby improving installation efficiency.

[0010] Optionally, a plurality of positioning protrusions are fixedly connected to the bottom of the midsole, and the support block is provided with positioning grooves for the positioning protrusions to engage.

[0011] By adopting the above technical solution, after the support block is inserted between the outsole and the midsole, the positioning protrusion on the bottom of the midsole inserts into the positioning groove to achieve the initial positioning of the support block, thus facilitating the subsequent fixing rod to fix the support block. During the user's movement, the positioning protrusion and the positioning groove work together to share the lateral shear force during the movement, thereby reducing the stress on the fixing rod and making the support block more stable and durable.

[0012] Optionally, the bottom of the base is provided with a protective cover for inserting into the fastening groove, the protective cover being interference-fitted with the fastening groove.

[0013] By adopting the above technical solution, the protective cover can effectively prevent mud, dust, and water from entering the fastening groove and countersunk groove, avoid contamination and corrosion of the fixing rod, and ensure the reliability of the locking function. Furthermore, the protective cover ensures that the bottom of the outsole is flat and smooth, without affecting the outsole's grip.

[0014] Optionally, a locking groove is provided at the end of the fixing rod away from the support block.

[0015] By adopting the above technical solution, users can use special hex wrenches and other tools to tighten or loosen the fixing rod by inserting them into the locking groove, thereby achieving a better fastening effect and ensuring the stable installation of the support block.

[0016] Optionally, the arch of the midsole is provided with an energy storage groove along the width direction, and the arch of the outsole is bent towards the side close to the inner top wall of the energy storage groove.

[0017] By adopting the above technical solution, the energy storage groove creates an arch effect at the arch of the foot in the midsole. During exercise, the energy storage groove can guide the arch of the midsole to deform efficiently and store energy during the gait cycle, releasing energy when pushing off the ground to provide a certain amount of propulsion. The outsole bends upward to form an arch structure, providing support for the energy storage groove, thereby effectively resisting excessive torsion of the sole during exercise and improving stability.

[0018] Optionally, the midsole has a plurality of grooves on the side away from the outsole, and the number of grooves gradually decreases from the ball of the foot toward the side closer to the heel.

[0019] By adopting the above technical solution, since the forefoot undergoes significant flexion during human movement, the foot area of ​​the shoe sole needs to have greater flexural flexibility. Therefore, the foot area has more grooves to ensure the flexibility of forefoot flexion. Because the heel area requires greater stability, fewer grooves are used there, allowing the heel to maintain stability while still possessing a certain degree of flexural flexibility.

[0020] Optionally, the sole bottom has several bending guide grooves at the ball of the foot and the heel, and the bending guide grooves are arranged along the width direction of the sole.

[0021] By adopting the above technical solution, multiple flex guide grooves create multiple flex lines on the sole of the shoe. During walking or running, the shoe can naturally bend along these guide grooves, better conforming to the human gait and allowing for greater freedom of movement of the feet. At the same time, these grooves also increase the ground contact pattern on the outsole, improving multi-directional grip to a certain extent.

[0022] In summary, this application has the following beneficial effects: 1. By setting up detachable support blocks, users can replace different support blocks according to the usage scenario, thereby bringing different cushioning hardness and rebound feedback. There is no need to buy multiple pairs of sports shoes to adapt to different scenarios, which has better economy and practicality.

[0023] 2. By setting up energy storage grooves and bending guide grooves, the sole can provide users with a certain amount of propulsion during exercise, and provide better flexibility and optimize gait guidance, thereby bringing a better sports experience. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a shock-absorbing sports shoe sole. (Refer to...) Figure 1 The cushioned athletic shoe sole includes an outsole 1 and a midsole 2 connected to the top of the outsole 1. The outsole 1 is made of rubber, and the midsole 2 is made of EVA. A support block 3 is detachably connected between the outsole 1 and the midsole 2 at the heel. The support block 3 has a cushioning hole 31 in the center. When the user exercises, the impact force at the heel is preferentially transmitted and concentrated at the edge of the cushioning hole 31, making the area of ​​the cushioning hole 31 more prone to compression and bending deformation, thereby achieving a cushioning effect.

[0028] The damping performance of the support block 3 can be adjusted by changing the parameters of the damping hole 31. When the hole is larger, the structural rigidity will decrease, resulting in greater deformation and thus providing softer and deeper damping. When the hole is smaller, the structural rigidity will decrease slightly, resulting in smaller deformation and thus providing more stable and sensitive rebound.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The outsole 1 has a fastening groove 11 at the bottom of the heel. A countersunk groove 12 is formed on the top wall of the fastening groove 11. A fixing rod 13 is threaded through and connected to the top wall of the countersunk groove 12. The support block 3 has a fixing groove 32 for threaded connection of one end of the fixing rod 13. After inserting the support block 3 between the heels of the outsole 1 and the midsole 2, the fixing rod 13 in the countersunk groove 12 is rotated, causing it to insert into the fixing groove 32, thus completing the threaded connection with the support block 3. To disassemble the support block 3, the fixing rod 13 is reversed, causing it to disengage from the fixing groove 32, allowing for the removal and replacement of the support block 3. The fixing rod 13 is made of reinforced PA6 material, providing high rigidity while maintaining a light weight.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The fixing rod 13 has a locking groove 131 at the end away from the support block 3. The locking groove 131, together with tools such as a hex wrench, can easily tighten or loosen the fixing rod 13, thereby facilitating the user to perform tightening operations and ensuring the stable installation of the support block 3.

[0031] Reference Figure 2 , Figure 3The end of the fixing rod 13 furthest from the support block 3 is submerged in the countersunk groove 12. A protective cover 14 is provided at the bottom of the outsole 1 for insertion into the fastening groove 11. The protective cover 14 is interference-fitted with the fastening groove 11, and the top wall of the protective cover 14 abuts against the inner top wall of the fastening groove 11. The interference fit of the protective cover 14 into the fastening groove 11 creates a sealed environment, effectively preventing mud, dust, and water from entering the fastening groove 11 and the countersunk groove 12, avoiding contamination and corrosion of the fixing rod 13, and ensuring the reliability of the locking function. Simultaneously, it ensures a smooth and even bottom at the heel of the outsole 1, without affecting the outsole 1's grip.

[0032] Reference Figure 4 A guide post 21 is fixedly connected to the bottom wall at the heel of the midsole 2. The guide post 21 is set along the width direction of the midsole 2. A guide groove 33 is opened on the top of the support block 3 for the guide post 21 to be inserted. The guide post 21 and the guide groove 33 cooperate to make the support block 3 slide only along the guide post 21, thereby facilitating positioning.

[0033] Reference Figure 4 Several positioning protrusions 22 are fixedly connected to the bottom wall of the heel of the midsole 2. The positioning protrusions 22 are hemispherical, and the support block 3 has a positioning groove 34 for the positioning protrusions 22 to engage. When the support block 3 is installed, during the pushing process, the hemispherical positioning protrusions 22 are compressed and slide into the positioning groove 34. At this time, the user can clearly feel the appearance and disappearance of the damping, which indicates that the support block 3 has reached the predetermined position, thus realizing the initial positioning of the support block 3, which is convenient for the subsequent fixing rod 13 to fix the support block 3.

[0034] Reference Figure 1 The midsole 2 has an energy storage groove 23 along its width on the bottom wall at the arch. The outsole 1 bends towards the inner top wall of the energy storage groove 23 at the arch. The energy storage groove 23 creates an arch bridge effect at the arch of the midsole 2. When the user is exercising, the energy storage groove 23 can guide the arch of the midsole 2 to deform efficiently and store energy during the gait cycle, and release energy when pushing off the ground, thereby providing a certain amount of propulsion.

[0035] Reference Figure 5 The midsole 2 has several grooves 24 on the side away from the outsole 1, and the number of grooves 24 gradually decreases towards the heel along the length of the midsole 2. The grooves 24 allow the midsole 2 to bend relatively easily. During exercise, the forefoot flexes significantly, so the forefoot area of ​​the sole needs greater flexibility, requiring more grooves 24 in the forefoot area of ​​the midsole 2. Because the heel area requires greater stability, fewer grooves 24 are present there, allowing for a degree of flexibility while maintaining stability.

[0036] Reference Figure 1 , Figure 2 The outsole 1 has several bending guide grooves 15 at the ball of the foot and the heel, which are arranged along the width of the outsole 1. The bending guide grooves 15 make the sole form multiple bending lines. When the user exercises, the sole can bend naturally along these bending guide grooves 15, which is more resistant to the human gait and can reduce cracking and damage caused by bending, thus improving the durability of the shoe.

[0037] The implementation principle of a shock-absorbing sports shoe sole in this application embodiment is as follows: When it is necessary to adjust the shock-absorbing and rebound performance of the shoe, the protective cover 14 is opened, the fixing rod 13 is rotated so that the fixing rod 13 is dislodged from the countersunk groove 12. At this time, the support block 3 can be taken out, and the support block 3 with different shock-absorbing holes 31 is replaced. It is then inserted between the outsole 1 and the midsole 2 along the guide rod, and the fixing rod 13 is rotated and inserted into the fixing groove 32 to complete the fixing.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
