Description

Functional outsole for fall prevention

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an outsole of a shoe for preventing a fall accident, and more particularly, to an outsole capable of reducing a fall accident rate by providing a specific structure to an outsole to increase frictional force with the ground.

Falling accident is an accident that falls abruptly and causes injury to the musculoskeletal system. It occurs mainly in the elderly, but falls frequently occur in young people due to marble and tiles installed to create aesthetic appearance of the building.

In addition, factors causing the fall can be classified into physical factors such as anemia or heart disease, behavioral factors due to drunkenness or decrease in the activity of the individual, and environmental factors caused by the inside or outside road environment.

Among them, environmental factor is the most important factor of fall injury regardless of gender and age, and various functional shoes are used to control the environmental factors of such fall accident.

In general, the structure of the shoe is composed of an upper which protects the foot and joints, and a sole which protects the bottom. The sole is made up of insole, midsole and outsole.

Among them, in the case of outsole, it is exposed to the outside and is in contact with the ground. In order to prevent falls, a demand for the friction force of the outsole is essential.

In addition, the outsole should be able to cope with the uneven ground state properly when walking, and the friction between the ground and the outsole is reduced especially when there is moisture on the road surface and when moisture or oil film forms on the ground surface , A slip prevention function is further required.

Particularly, according to the above-mentioned tendency that the fall accident rate due to environmental factors is increasing, a slip prevention function is commonly required for outsole of a general shoe, and various researches on outsole that can increase the frictional force with the ground are being conducted.

Typically, the anti-slip shoe sole structure of Patent Application No. 10-2010-0103139 (filed on October 21, 2010) filed with the Korean Intellectual Property Office minimizes the occurrence of slippage by maximizing the frictional force with respect to the ground before and after landing Technology.

However, this has a problem that the coefficient of friction of the outsole can be drastically reduced by the water film or the oil film that can be formed at the interface of the paper surface.

In addition, in the case of a shoe sole for anti-slip of Patent Application No. 10-2009-0078951 (filed on August 25, 2009) filed by the Korean Intellectual Property Office, there is disclosed a technique for increasing frictional force by binding a separate spike member to the bottom surface of an outsole, There is a problem in that the production efficiency can be reduced because a process of separately joining members having different physical properties in the outsole manufacturing process is added.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to improve the gripping force of an outsole while resolving a water film or oil film, And to provide a functional outsole for preventing fall which has excellent frictional coefficient without causing a decrease in production efficiency in the manufacture of outsole using the same material as the whole material of the outsole.

In order to achieve the above-mentioned object, the present invention provides a functional outsole for preventing falls, which has a predetermined thickness and has a shape in which a front part of a floor surface rises upward, and a wavy- A plurality of first protrusions protruding from the bottom surface of the body so as to have a gap therebetween and having an imaginary extension line extending outward from the center of the polygonal plane, Wherein the first incision groove is formed to have a step with the first incision groove and to partially extend the incision area of the first incision groove, the incision width being shorter than the incision length of the first incision groove, And the depth of the incision is shallower than the incision depth of the first incision groove, And a second slip prevention portion formed on the bottom surface so as to have a protruding thickness smaller than the protruded thickness of the first non-slip portion, wherein the first slip prevention portion includes a second slip prevention portion and a second slip prevention portion, And a prevention part.

The first non-slip portion may be disposed on the bottom surface of the body such that centers of the polygonal planes are equally spaced.

The present invention provides a plurality of slip prevention portions having stepped portions and having a specific structure so as to prevent a decrease in frictional force caused by an oil film or a water film formed at the interface of the paper surface, do.

In addition, since the non-slidable portion has a different projection height, the impact force travel path from the ground to the sole can be increased, thereby providing an excellent buffering effect.

In addition, since the material of the outsole is made of a single material, it is not necessary to add a molding step, and productivity is improved.
