As shown in the drawings, the anti-slip shoe sole 100 of the two-tiered structure according to the embodiment of the present invention is characterized in that in the shoe sole 1,

A first friction protrusion 10, and a second friction protrusion 20, as shown in Fig.

As shown in FIGS. 1 and 2, the first friction protrusions 10 are protruded downward from the bottom surface of the sole 1 so as to be frictionally engaged with the ground surface, thereby preventing slippage of the shoe.

5, the height h1 of the first friction protrusion 10 is higher than that of the second friction protrusion 20 to be hung, so that the first friction protrusion 10 Is frictionally contacted with the ground to stably prevent slippage of the shoe.

1 and 2, a plurality of the second friction protrusions 20 protrude downward from the bottom surface of the sole 1, and a height h1 of the first friction protrusions 10, Is formed to have a lower height (h2).

That is, as shown in FIG. 5, at first, the first friction protrusion 10 rubs against the ground to stably prevent the shoe from slipping, and when the first friction protrusion 10 is gradually The second friction protrusion 20 is naturally frictioned against the ground to stably prevent the slippage of the shoe, thereby effectively preventing slippage of the shoe for a long period of time.

Although the frictional protrusions 10 and 20 are embodied in the form of "-" and "? &Quot;, the frictional protrusions 10 and 20 are not limited to these shapes. Of course.

3, a friction pad 30 having an excellent frictional force is further formed on the bottom surface of the friction protrusions 10 and 20,

As shown in FIG. 6, when the shoe is worn, slippage is prevented by an excellent frictional force between the friction pad 30 formed on the lower portion of the first friction protrusion 10 and the ground, thereby inducing stable walking, When the friction pad 30 formed on the first friction protrusion 10 is worn out and consumed for a long period of time, the friction pad 30 formed on the second friction protrusion 20 is frictionally formed on the ground, The frictional pad 30 can be guided to effectively prevent slippage of the shoe for a long period of time.

3, the lower portion of the friction pad 30 formed on the second friction protrusion 20 is formed on the upper surface of the friction pad 30 formed on the first friction protrusion 10, As shown in FIG.

6, before the friction pad 30 formed on the first friction protrusion 10 is completely worn out and consumed, the friction pad 30, which is formed on the second friction protrusion 20, It is preferable that the lower portion is brought into contact with the ground surface so that the sliding of the shoe is prevented stably through the friction pad 30 until all the friction pads 30 are consumed.

If the lower portion of the friction pad 30 formed on the second friction protrusion 20 is formed farther from the ground than the upper portion of the friction pad 30 formed on the friction protrusion 10, Even if the frictional pad 30 formed on the frictional protrusion 10 is completely consumed, a time during which the frictional pad 30 formed on the second frictional protrusion 20 can not contact the ground is formed, The slip of the shoe can not be stably prevented, thereby forming the position of the friction pad 30 as described above.

Here, the friction pad 30 is formed of a rubber material having excellent frictional force. However, it is needless to say that the friction pad 30 is not limited to such a material but may be embodied by various materials and shapes having excellent friction.

The non-slip type shoe sole 100 of the present invention having the above-described components has a plurality of first friction protrusions 10 and second friction protrusions 10 having different heights from each other on the bottom of the shoe sole 1, The first rubbing protrusion 10 is first in contact with the ground surface by friction against the ground to prevent slippage of the shoe, and the first rubbing protrusion 10 is prevented from sliding due to long- If the height of the second friction protrusion 20 is lowered by abrasion, the second friction protrusion 20 may be frictionally engaged with the ground to prevent slippage of the shoe, thereby effectively preventing slippage of the shoe for a long time.

Further, the friction pad 30 having a high frictional force is formed on the bottom surface of the first friction protrusion 10 and the second friction protrusion 30 to prevent the shoe from slipping more effectively, Since the friction pad 30 formed on the second friction protrusion 20 contacts the ground when the friction pad 30 formed on the second friction protrusion 10 is worn out and exhausted, There is an expected effect.

The non-slip type shoe sole 100 according to another embodiment of the present invention having the above-described structure can prevent slipping as follows.

First, when walking is started by wearing a shoe sole 100 having a two-stage structure of the present invention,

As shown in FIG. 6, at first, the friction pad 30 formed on the lower portion of the first friction protrusion 10 is frictionally contacted with the ground surface, so that stable walking is induced in a state where sliding is prevented, When the friction pad 30 formed on the friction protrusion 10 is worn out and consumed, the friction pad 30 formed on the second friction protrusion 20 is naturally frictioned with the ground, thereby inducing stable walking.

The shoe sole 100 having the two-stage structure according to the present invention is formed by the superior frictional force of the friction pad 30 formed on the first friction protrusion 10 and the second friction protrusion 20 Long-term effective prevention of slipping shoes.

Meanwhile, the sole 1 of the two-stage non-slip type shoe sole 100 according to another embodiment of the present invention can be manufactured to include a stone powder together with a rubber material in order to secure excellent frictional force, Because of the characteristic of the rubber material, excellent cushioning force is ensured and it is possible to induce comfortable walking of the wearer.
