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

[0002] The sole of a shoe consists of the insole, midsole, and outsole from top to bottom. For some shoes, especially athletic shoes, people want their feet to be effectively protected during exercise to reduce the damage caused by shock, so as to achieve the purpose of training or competition. When one side of the sole steps on a protrusion, the reaction force of the ground will act in both the vertical and parallel directions of the sole. Since the foot joints are more vulnerable in the parallel direction of the sole, it is easy to sprain the ankle. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, such as Figure 1 , 2 As shown, a cushioning and anti-ekle outsole includes anti-ekle blocks 3. The outsole 2 has multiple sets of anti-ekle blocks 3 arranged in parallel below it. Each set of anti-ekle blocks 3 is arranged in pairs on the left and right sides of the outsole 2. The anti-ekle blocks 3 are slidably disposed within cushioning chambers 4. Multiple cushioning chambers 4 are arranged in parallel within the outsole 2. Anti-ekle grooves 5 are formed on both sides of the outsole 2, with the height of the anti-ekle grooves 5 located at the upper end of the cushioning chambers 4. Each pair of symmetrical anti-ekle blocks 3 is connected by a compensation mechanism 1. When one side of the outsole steps on a protrusion, the anti-ekle groove 5 provides additional deformation cushioning and shock absorption, keeping the insole as parallel to the ground as possible. The anti-ekle block 3 on the same side is compressed and raised, and the compensation mechanism 1 supports the anti-ekle block 3 on the other side downwards, keeping the insole as parallel to the ground as possible.

[0023] To achieve the function of raising the anti-sprain block 3 on one side of the compensation mechanism 1 to lower the anti-sprain block 3 on the other side, the compensation mechanism 1 includes an arc-shaped elastic plate 6 and a connecting piece 7, such as... Figure 3 As shown, one end of the anti-sprain block 3 is in contact with the ground, and the other end is hinged to the bottom end of the arc-shaped elastic plate 6. The arc-shaped elastic plate 6 has an outward opening, and its upper end is hinged to the top surface of the buffer cavity 4. A connecting piece 7 is slidably arranged inside the buffer cavity 4. The two ends of the connecting piece 7 are respectively movably arranged on each arc-shaped elastic plate 6. The arc-shaped elastic plate 6 has holes, and the two ends of the connecting piece 7 extend into the holes in the arc-shaped elastic plate 6. Figure 4 As shown, the connecting piece 7 has hooks 18 and baffles 9 fixed at both ends, which can transmit tensile and thrust forces. The arc-shaped elastic plate 6 is connected to the connecting piece 7 at the inside of the hooks 18 and the outside of the baffles 19. When one side of the outsole steps on the protrusion, the anti-twist block 3 on the same side will be compressed and rise, causing the arc-shaped elastic plate 6 to deform inward, pushing the connecting piece 7 to the other side, causing the arc-shaped elastic plate 6 on the other side to deform outward, driving the anti-twist block 3 to support downward, so that the insole remains as parallel to the ground as possible.

[0024] A protrusion 8 is fixed to the back of the anti-sprain groove 5, and the protrusion 8 extends to the arc-shaped elastic plate 6. The protrusion 8 and the arc-shaped elastic plate 6 interact with each other, so that the anti-sprain groove 5 and the anti-sprain block 3 cooperate with each other, enhancing the buffering and anti-sprain effect.

[0025] Example 2: To achieve the function of raising the anti-ejection block 3 on one side of the compensation mechanism 1 to lower the anti-ejection block 3 on the other side, the compensation mechanism 1 includes link A 9, link B 10, and link C 11, as follows: Figure 5 As shown, one end of the anti-sprain block 3 is in contact with the ground, and the other end is hinged to the bottom end of link A 9. The top end of link A 9 is hinged to the bottom end of link B 10, and the top end of link B 10 is hinged to the top surface of the buffer cavity 4. One end of link C 11 is hinged to the hinge point of link A 9 and link B 10, and the other end is hinged to the hinge point of link A 9 and link B 10 on the other side. When one side of the outsole steps on a protrusion, the anti-sprain block 3 on the same side will be compressed and raised, making the angle between link A 9 and link B 10 smaller, pushing link C 11 to the other side, making the angle between link A 9 and link B 10 on the other side larger, causing the anti-sprain block 3 to support downwards, so that the insole remains as parallel to the ground as possible.

[0026] The remaining features are the same as in Example 1.

[0027] Example 3: To achieve the function of raising the anti-ejection block 3 on one side of the compensation mechanism 1 to lower the anti-ejection block 3 on the other side, the compensation mechanism 1 includes a trapezoidal connecting block 13, such as... Figure 6 As shown, one end of the anti-sprain block 3 contacts the ground, and the other end forms an inclined surface 12. One side of the trapezoidal connecting block 13 contacts the inclined surface 12 of the anti-sprain block 3, and the other side contacts the inclined surface 12 of another anti-sprain block 3. A pressure plate 14 is provided on the upper surface of the trapezoidal connecting block 13. The pressure plate 14 is fixed under the top surface of the buffer cavity 4 and is elastic. When one side of the outsole steps on the protrusion, the anti-sprain block 3 on the same side will be compressed and rise. The inclined surface 12 rises, pushing the trapezoidal connecting block 13 to move along the common normal of the contact surface, causing the inclined surface 12 on the other side to descend, driving the anti-sprain block 3 downward for support, so that the insole remains as parallel to the ground as possible. The pressure plate 14 is elastic and can help the trapezoidal connecting block 13 return to its original position. A roller is hinged to the end of the pressure plate 14 to reduce friction.

[0028] The remaining features are the same as in Example 1.

[0029] Example 4: To achieve the function of raising the anti-ejection block 3 on one side of the compensation mechanism 1 to lower the anti-ejection block 3 on the other side, the compensation mechanism 1 includes a connecting block 16, such as... Figure 7As shown, one end of the anti-ejection block 3 contacts the ground, and the other end forms a curved surface 15. The side of the connecting block 16 is also curved. One side of the connecting block 16 contacts the curved surface 15 of the anti-ejection block 3, and the other side contacts the curved surface 15 of the anti-ejection block 3 on the other side. Rollers 17 are respectively provided on the upper and lower surfaces of the connecting block 3, and the rollers 17 are hinged in the buffer cavity 4. When one side of the outsole steps on the protrusion, the anti-ejection block 3 on the same side will be compressed and rise. The curved surface 15 rises, pushing the connecting block 16 to the other side, causing the inclined surface 12 on the other side to descend, which in turn drives the anti-ejection block 3 downward for support, so that the insole remains as parallel to the ground as possible. The rollers 17 restrict the rotation of the connecting block 16 in the buffer cavity 4 and reduce friction.

[0030] The remaining features are the same as in Example 1.
