Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Patent Application No. 20-2014-2501 filed on Mar. 28, 2014, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

The present invention relates to outsole for shoe through which air circulation and impact absorption are simultaneously achieved, and more particularly, the present invention relates to outsole for shoe in which elastic tubes that are deformed and restored by push-pressure are arranged in a space between the upper sole and the bottom sole thereof, such that air within the space is ventilated through the inside of shoe when the elastic tubes are deformed and recovered and at the same time impact applied to a human body through the soles of feet is loosened therethrough.
Generally, Korean Patent Registration No. 907740 discloses a technology in which an impact absorbing elastic portion having a column-shape elastic member is vertically installed on the bottom surface of insole and Korean Patent Laid-Open Publication No. 20-2007-0001144 discloses a technology in which an elastic means having horizontal pumping tubes is installed in a groove formed on a bottom sole.
According to the related art disclosed in Korean Patent Registration No. 907740, it has a problem that column-shaped elastic members are charged in the inside thereof as a floor material, and thus each column-elastic member is repeatedly inclined in the same direction or in a different direction and is restored during walking and may result in a sprained ankle or falling down.
Further, a shoe sole disclosed in Korean Patent Laid-Open Publication No. 20-2007-0001144 has a problem that each pumping tube of an elastic means is horizontally installed in the groove of an outsole, and thus the cross-sectional surfaces of each pumping tube are maintained in the pressed state rather than maintaining the original shape during walking and thus internal air circulation becomes insignificant.

SUMMARY

The present invention has been proposed to solve the above drawbacks and an object of the present invention is to provide an outsole for shoe in which air circulation and impact absorption are simultaneously achieved by installing a plurality of elastic tubes in a space between an upper sole and a lower sole, which are shaped-deformed and restored, allowing air within the space to be ventilated through the inside of shoe when the elastic tubes are shape-deformed and restored, and allowing an impact applied to a human body through the soles of feet to be softened.
An aspect of the present disclosure may provide an outsole for shoe wherein the lower surface of a boundary (112) of an upper sole (110) on which an elastic plate (114) is horizontally formed, and an upper surface of a boundary (122) formed around a bottom sole (120), on which a bottom surface (122 a) and an upper surface (122 b) are formed, are fixed, the air cushion outsole may including: a space (140) formed between the elastic plate (114) of the upper sole (110) and the upper surface (122 b) of the bottom sole (120); an elastic tube (116) which is formed in the form of a hollow cylinder, through which the upper and bottom holes (116 a) (116 b) are formed while having the same center wherein the elastic plate (114) is continuously connected to the outer circumferential surface of the upper hole (116 a) , which is arranged vertically with the space (140); and an adhesive sheet (130) which closes each bottom hole (116 b) of the elastic tube (116) and is fixed to the upper surface (122 b) of the bottom sole (120).
The elastic tubes (116) may be arranged and installed from a ball of the sole of a foot to a heel thereof and vent holes (114 a) communicated with the space (140) are formed on the elastic plate (114).
An air discharging tube (150) communicated with the space (140) may be horizontally installed on the boundary (112) of the upper sole (110).
