Description

Shoes with a pin protrusion structure}

The present invention relates to a shoe having a means for preventing slipping therein, and more particularly, a risk of falling such as on an icy road due to a plurality of pins protruding vertically downward of an outsole in conjunction with a lever rotating by an external force. It relates to shoes that allow users to walk safely even in the presence of

In general, various shapes are formed on the outsole of shoes for the purpose of improving friction with the ground, but it is difficult to achieve the purpose on snowy or icy roads where it is difficult to form a sufficient level of friction due to a decrease in friction coefficient For this reason, a fall accident may occur in which a pedestrian slips and falls on a snowy or icy road.

Since these falls can lead to serious injury or death to the person involved, careful attention of pedestrians is always necessary on snowy or icy roads. We need a more fundamental solution to solve this problem.

In addition, there are crampons (official name: Steig Eisen), which are equipment that can be combined with shoes to prevent slipping on snowy or icy roads, etc. It can be said to be practically difficult to use.

Therefore, various inventions related to practical devices or shoes that can be easily used for the purpose of preventing slipping on snowy or icy roads are required, and in relation to these requests, Korean Utility Model Publication No. ”, Republic of Korea Utility Model Registration No. 20-0229822 “shoes with anti-slip device” and Republic of Korea Utility Model Registration No. 20-0459546 No. 20-0459546 Inventions such as “shoes with anti-slip device” have been proposed and disclosed. there is.

First of all, the “anti-slip shoe” of the Republic of Korea Utility Model Publication No. 1996-0003230 has a structure in which the spike protrudes downward by the forward and backward movement of the push rod, so it can be used in the form of a general shoe heel, but it can be used on snowy or ice In a situation where there is a risk of falling, such as a road, an invention related to a shoe heel that enables a user to walk safely by a downward protruding spike has been proposed.

In addition, in the “shoes with anti-slip device” of Korean Utility Model Publication No. 20-0229822, a nut tube with a nut ball exposed to the outside is buried on the bottom surface, so it can be used in the form of a general shoe, but it can be used in the form of a normal shoe, In a situation where there is a risk of falling, such as on an icy road, an invention related to a shoe that enables a user to walk safely by a spike protruding downward has been proposed by screwing a spike plate to the nut ball.

In addition, the “shoes with anti-slip device” of Korean Utility Model Publication No. 20-0459546 has a structure in which an internal anti-slip protrusion is exposed to the outside when the cover is separated from the heel, so that it is usually in the form of a general shoe. However, in situations where there is a risk of falling, such as on a snowy road or an icy road, an invention related to a shoe that enables a user to walk safely by means of non-slip protrusions exposed to the outside has been proposed.

However, the method proposed in “Shoes for non-slip” of the Republic of Korea Utility Model Publication No. 1996-0003230 has a large number of spikes inside the shoe as the structure of the device for protruding spikes is complicated and the installation area is wide. A problem that is difficult to do occurs, and for this reason, a problem in that the efficiency of the anti-skid is lowered.

In addition, the method proposed in “Shoes with an anti-slip device” of Republic of Korea Utility Model Registration No. 20-0229822 requires the user to carry a plurality of spike plates, and screw the prepared plurality of spike plates to the nut hole one by one, or Inconvenience in use that must be separated occurs, and the method proposed in “Shoes with an anti-slip device” of Korean Utility Model Publication No. 20-0459546 removes the cover from the heel and the surface is contaminated by the user. Inconvenience in use arises in that it must be carried and then combined again.

Therefore, by solving all of the above problems, it is possible to provide excellent effects to the user, and at the same time, it can be said that the present invention related to a practical anti-slip means that is easy to use is required again.
