Embodiment Construction

[0017] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] refer to figure 1 , figure 2 , image 3 , Figure 4 , the rebound boosting device for the heel of the sole comprises a booster body A assembled on the heel of the sole 2, and the sole is preferably an EVA sole. The booster body A is composed of a plurality of unit bodies 1, preferably the unit bodies 1 are made of TPU material. The unit body 1 is an arc-shaped elastic member bent in a C-shape or an oblique U-shape, and the opening of the unit body 1 faces backward. Each unit body 1 is bent to form a slot 10 extending along the width direction of the sole 2 . The top surfaces of the two ends 11 of the unit body 1 are respectively connected with the sole 2 . The plurality of unit bodies 1 constituting the above-mentioned booster body A are connected sequentially in a U-shape and symmetrically distributed in left and right mirror surfaces. The ...

Abstract

The invention relates to a rebound assisting device for a sole heel. The rebound assisting device comprises an assisting body assembled on the sole heel. The assisting body is formed by a plurality of unit bodies which are C-shaped elastic pieces bent in an arc mode, openings of the unit bodies face backwards, and the top faces of the two ends of each unit body are connected with a sole. The unit bodies are connected in sequence to be distributed in a U shape, the two adjacent ends of every two adjacent unit bodies are bonded in an overlapped mode or integrally connected. By means of the structure mode of the unit bodies, the rebound assisting device has good deformation capability; by means of the structure of U-shaped distribution and integral connection through the connecting pieces, the damping effect of the sole heel and the protection effect on the heel can be easily improved, and the left and right lateral anti-skidding and side-overturning-preventing capability of the sole heel can also be improved; in addition, the two ends of the unit bodies can generate obliquely-forward rebound force on the sole, the rebound rate of strength reaches 35% to 52%, and forward push assistance is provided for athletes.

Description

technical field [0001] The invention relates to a component of a shoe sole, in particular to a rebound assisting device for the heel of the 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 la...
