Shock-absorbing shoes with wave type spring pads

Abstract

The invention discloses a pair of shock absorbing shoes with wave type spring pads. Each shoe is provided with a middle sole and an outer sole, wherein the middle sole covers an upper sole; the outer sole is internally provided with groove bottoms of built-in grooves; the built-in grooves are internally provided with shock absorbing springs wound from flat steel wires; the wire width of each spring is larger than the wire thickness; the flat steel wires are wound into multi-layered integrated spring pads in a unidirectional way; the peaks and the valleys of the flat steel wires are staggered;the peaks at any layer of flat steel wire are in contact with the valleys at the upper layer of flat steel wire; the valleys at any layer of flat steel wire are in contact with the peaks at the lowerlayer of flat steel wire; either the peak or the valley occurs more than twice in the section where the flat steel wire is wound once; upper supporting pieces are arranged in the built-in grooves of a front sole support and a rear sole support of the outer sole; and the wave type spring pads are arranged between the upper supporting pieces and lower supporting pieces. In the shoes, the space needed for buffering external force is reduced, so the size of the shoes can be reduced, simultaneously more load can be born, and more external force can be buffered.

Description

technical field [0001] The present invention relates to a spring pad for cushioning parts and a shoe using the spring pad, in particular to a wave spring pad capable of ensuring cushioning force in a narrow space, improving lateral resistance and ensuring mechanical reliability, and a shoe with the spring pad . Background technique [0002] With the development of sports-related technology, new sporting goods are constantly coming out. Among these sporting goods, shoes are used the most. Sports shoes, represented by sports shoes, have some protective devices to protect the wearer's spine, lower limb joints, and muscles from injury during various intense activities. [0003] This type of device is mainly placed on the outsole of the shoe to absorb shock and fully transmit the wearer's power to the ground. Typical protection devices include buffers such as shock-absorbing air cushions and springs. Buffers such as air cushions or springs are installed between the wearer's f...

AI Technical Summary

Problems solved by technology

Although the coil spring is low in cost and easy to control the forming size, it has problems such as a high space occupation rate required for providing elasticity and a decrease in elasticity during long-term use.

In addition, it has poor resistance to lateral forces perpendicular to the winding direction and is easily deformed
