Functional shoes

Abstract

The invention relates to a functional shoes provided with a helical spring on the sole, which comprises the following components: an upper sole with a plurality of mounting grooves on the bottom surface; a lower sole with a plurality of mounting grooves on a surface corresponding to the upper sole; a screw spring mounted between the upper sole and the lower sole; a first and a second main supporting structure, which forms a spring groove that accommodates the upper / lower end of the screw spring respectively; a first and a second secondary supporting structure, which forms an enclosed pluggingprotrusion that makes the spring grooves closed respectively; a support frame, which is combined on the upper side of the second main supporting structure; a first and a second combination member, which remains the first main supporting structure with the first secondary supporting structure and a second main supporting structure with a second secondary supporting structure wrap the upper / lower end of the helical spring, and inserts into the mounting grooves on the upper and the lower sole for fixation. The shoes can effectively absorb impact transmitted to the upper / lower end of the screw spring and disperse load evenly with simple assembly, and can firmly and stably remain its assembly status.

Description

technical field [0001] The present invention relates to a shoe with a helical spring installed on the sole, in particular to a shoe that can effectively absorb the impact transmitted to the upper / lower end of the helical spring and evenly distribute the load, which is simple and easy to assemble, and can maintain its assembled state firmly and stably functional shoes (Functional footwear). Background technique [0002] Recently, shoes with cushioning means on the soles to reduce the impact and fatigue of the feet during walking or running have become popular as sports shoes and game shoes, especially so-called springs that use the elastic deformation force of coil springs. Shoes come and go. [0003] For example, a shoe is disclosed in Korean Patent Registration No. 10-0342173, such as figure 1 As shown, it is characterized in that: the sole (12) comprising the foot support member (10) is composed of a first part (16) with an inner side, a second part (18) with an inner / ou...

Problems solved by technology

However, the problem with this kind of spring shoes for games is that when the sole contacts with the ground in an excessively twisted state, the spring will be slightly detached from the sole, which is slightly insufficient in safety.

Moreover, since the conical and helical springs need to pass through the insertion holes one by one to be inserted into the fixing area, it is very inconvenient to combine the springs between the fixing plate and the fixing frame at the same time.

[0006] In addition, when the wearer continues to walk irregularly, the sole of the shoe will be partially worn, and it will appear one-sided under the action of an external force, resulting in a loss of spring compression stress, which will greatly reduce the load resistance of the shoe.
