Damping and torsion-resisting element for shoe sole

Abstract

The invention provides a damping and torsion-resisting element for a shoe sole. The damping and torsion-resisting element comprises a substrate, wherein positioning sheets extend from both sides of the substrate along the width direction of the substrate respectively, and are divided into an upper positioning sheet and a lower positioning sheet; the upper positioning sheet obliquely extends upwards, and then extends upwards in a bending way; the lower positioning sheet obliquely extends downwards, and then extends downwards in a bending way; bending positions are in circular transition; the middle parts of the upper positioning sheet and the lower positioning sheet are hollowed; the upper positioning sheet and the lower positioning sheet are distributed in a staggered way; and the middle part and the end part of the upper positioning sheet and the lower positioning sheet cling to the two outer side walls of a middle sole and an inner sole, so that the peripheries of shoe waists of themiddle sole and the inner sole are supported in a jointing way. The damping and torsion-resisting element has damping, supporting, shaping, rebounding and stabilizing functions, can be taken as a damping element applied to a thin position on the shoe sole for effectively absorbing and eliminating front face and side face impact force of the ground on feet, and can automatically restore to the original shape to prevent the shoe sole from being deformed excessively in a torsional way and prevent the feet from being wrenched.

Description

technical field [0001] The invention belongs to the field of shoemaking, in particular to a shock-absorbing and torsion-resistant element capable of both shock absorption and anti-torsion. Background technique [0002] The shoe is mainly composed of the upper and the sole. Whether the shoe is comfortable or not depends first on the sole. The sole is the part of the shoe that is in direct contact with the ground. It is directly subject to the friction and impact of the ground, and at the same time transmits the reaction force of the ground to the foot. The sole includes the insole, midsole and outsole from top to bottom. For some shoes, especially for sports shoes, people hope that the feet can be effectively protected during sports, and the damage caused by vibration can be reduced to achieve the purpose of exercise or competition. The appearance of shock-absorbing soles meets this requirement. To meet this requirement, the shock-absorbing structure can not only buffer the ...

AI Technical Summary

Problems solved by technology

For example, the shock absorption design of common soles is a fully enclosed shock-absorbing airbag based on aerodynamic principles. However, once the seal of the shock-absorbing airbag is damaged and the air leaks, the shock-absorbing effect will be lost, and the shock-absorbing airbag is thick and soft. When the sole transmits the ground impact force to the sole of the foot, the shock-absorbing airbag is easy to be skewed and cannot be corrected, and the sole cannot be restored to its original shape to protect the foot from being sprained; there are also EVA high-elastic materials used to make the midsole, and its shock-absorbing effect only depends on The midsole itself has elasticity and acts as a shock absorber. Its shock absorber effect is not great, and it does not have anti-twist function.

The general shock-absorbing structure uses shock-absorbing columns, etc., which have a single function and only have a shock-absorbing function, and the shock-absorbing columns can basically only be used on the heel, because a higher heel can accommodate a longer vertical At the same time, the use of shock-absorbing columns also reduces the torsion resistance of the soles, and the movement stability is poor.
