Rebound shock-absorbing backsheet for shoe soles

Abstract

The invention relates to a springback shock absorption bottom piece for a shoe sole. The springback shock absorption bottom plate comprises a shock absorption body assembled on the shoe sole. The shock absorption body is composed of multiple unit bodies. The unit bodies are sequentially connected to be arranged in a U shape. The unit bodies are elastic parts which are bent in an arc shape to be in a C shape. The two ends of each unit body stretch in an obliquely-downward mode. The top faces of the unit bodies are fixedly glued to the shoe sole. The two adjacent ends of every two adjacent unit bodies are glued in an overlapped mode or integrally connected. Through the opening structural mode that the unit bodies are bent in the arc shape to be in the C shape, the unit bodies achieve good deformation capacity, treading pressure received by the shoe sole can be decomposed and unloaded, and a shock relieving body achieves a good shock relieving effect. During treading, the two ends of each unit body are bent in an obliquely-upward mode, obliquely-backward counter acting force is generated to the shoe sole, impact force between an athlete and the ground is further effectively absorbed, and the shock absorption rate of force reaches 43% to 80%.

Description

technical field [0001] The invention relates to a component part of a shoe sole, in particular to a rebound shock-absorbing bottom sheet for a shoe sole. Background technique [0002] When exercising, the impact force on the heel of the athlete is three times that of his own body weight. This force will generate shock waves that are more harmful to people, causing damage and pathological changes to tissues such as bones, muscles or joints. For this reason, having the sole of good cushioning function is one of the important ways to solve this problem. The current cushioning soles are mostly made by adding elastic cushioning devices such as air cushions, silicone cushions, and springs, or using materials with large deformations (such as EVA) to make soles, or through cushioning such as honeycomb structures and cushioning protrusions. Structure and other methods to achieve the purpose of cushioning. They either have complex structures, cumbersome production processes, or have...
