AI Technical Summary

Technical Problem

The single air cushion cavity of a traditional air cushion soles or insoles is large in size and has poor durability. Once the air cushion cavity is damaged, the shoe's cushioning and rebound function will be greatly reduced.

Method used

A sole and insole with an air cushion are designed. The air cushion consists of an outer capsule and a plurality of inner capsules. The inner capsule divides the inner cavity into multiple independent capsules. Each capsule is in a multilateral body shape, and there is no gap between the capsules. The size and air pressure of each capsule are relatively independent.

Benefits of technology

With this design, even if the outer side of the air cushion occurs, it will only affect the corresponding capsule cavity without causing the large area air cushion failure, significantly improving the durability and shock-absorbing and rebound performance of the soles and insoles.

Abstract

The utility model relates to the technical field of shoe soles, in particular to a shoe sole with an air cushion, which comprises a shoe sole body, at least one air cushion is arranged on the shoe sole body, each air cushion comprises an outer bag film and a plurality of inner bag films, the outer bag films are wrapped to form an inner cavity, and the inner bag films are positioned in the inner cavity. The inner capsule membranes divide the inner cavity into a plurality of mutually independent capsule cavities, and each capsule cavity is in a polygon shape; the utility model further relates to the insole with the air cushion, and the air cushion is the same as the air cushion in the sole body in structure. As the bag cavities in the air cushion are formed by dividing the outer bag film by the inner bag film, no gap exists between the bag cavities, the bag cavities are mutually independent, the air cushion is arranged on the sole or the insole, the whole functionality of the sole or the insole cannot be seriously influenced by the failure of the large-area air cushion caused by local damage of the outer side of the air cushion, the durability is higher, and the shock absorption resilience is higher; the shape and the size of the air cushion can be customized according to the concave-convex structure of the sole or the insole, and wider requirements are met.
