Title:
SOLE HAVING A HOLLOWED-OUT ENERGY STORAGE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/044939
Kind Code:
A1
Abstract:
A sole having a hollowed-out energy storage structure, relating to the field of soles. The sole comprises an upper sole (1), a midsole (2) and an outsole (3) which are sequentially arranged from top to bottom. The upper sole comprises a bottom layer (33), and a first air bag body (34) and a second air bag body (35) which are disposed on the surface of the bottom layer (33) and spaced apart. A third resilience storage device is disposed between the first air bag body (34) and the second air bag body (35) and corresponding to an arch position. The third resilience storage device comprises sliding blocks (36) disposed on the surface of the bottom layer (33), a fifth mounting slot (37) formed on the surface of the bottom layer (33), and third reset springs (39) and push pipes (38) mounted in the fifth mounting slot (37). When filled with air, the first air bag body (34) and the second air bag body (35) are charged instantly, providing high resilience. On the other hand, under the action of the two third reset springs (39), the two sliding blocks (36) generate counter-acting high resilience on the foot arch and heel, thereby further improving the resilience of the entire shoe sole, so that an athlete can save more labor in an exercise process.
