Shock-absorbing shoe using spring

Abstract

The present invention relates to a shock-absorbing shoe using a spring, comprising: a spring for absorbing shock by providing an elastic force; an outsole which constitutes the bottommost sole of a shoe; an upper sole which is fixed to the top of the outsole, has a gap between the heel part thereof and the heel part of the outsole so as to provide a space in which the spring is provided, and is lowed by the weight of a user or raised by the elastic force of the spring; a lower spring seat which is formed on the upper surface of the outsole and supports the lower end part of the spring; an upper spring seat which is formed below the bottom of the upper sole and supports the upper end part of the spring; and a raising and lowering guide for guiding the lowering and raising of the upper solestraightly.

Description

technical field [0001] The present invention relates to a shoe using a spring, and more specifically relates to a cushioning shoe using a spring in which the spring is arranged at the heel to buffer impact or load. Background technique [0002] Generally speaking, the role of shoes is to reduce fatigue on the feet by protecting the feet and absorbing certain shocks. [0003] In recent years, various types of functional shoes have been introduced in order to more smoothly absorb shocks, and especially shoes using springs to cushion shocks have been marketed. [0004] As a related prior art, a shock-absorbing shoe is proposed in Korean Patent Publication No. 10-1034656. [0005] In the prior art as described above, a coil spring as an elastic body is installed between the outer sole and the upper sole, and a fixing body for fixing the coil spring at the upper end and a lower end of the coil spring, and for holding the coil spring. A support member of the fixed body, and a co...

Problems solved by technology

[0007] However, as mentioned above, shock absorbers have always had the problem that when a certain load is continuously applied to and compresses the coil springs, severe shocks due to contact between the coil springs are transmitted, resulting in breakage and damage.

[0008] In particular, the buffer boot according to the prior art as described above has a structure in which a plurality of parts are combined, so that the number of parts and the manufacturing process are complicated, and a large amount of manual work is required, thereby reducing productivity.

[0009] In addition, the existing technology tends to have the problems of increased weight due to many parts, especially the deterioration of the function of shoes for the elderly and the weak, and the problems of noise and durability reduction due to each part

[0010] In addition, the prior art has always had the problem of lacking a structure capable of adjusting the spring force
