1 to 3, the stabilization according to the embodiment of the present invention has been described. 4 and 5, the use state of the safeguard according to an embodiment of the present invention will be described below.

FIG. 4 is a side view for explaining a first state (non-rotating state) of the stabilization according to the embodiment of the present invention, FIG. 5 is a side view for explaining a second state (rotation state) of the stabilization according to the embodiment of the present invention, Side view.

Referring to FIG. 4, the second cap 20 may not rotate with respect to the first cap 10. That is, the state where the middle part is not rotated with respect to the forefoot can be defined as the first state.

In the first state, the water W introduced through the first ventilation opening 30 may be blocked by the upper surface of the first cap 10.

Specifically, when the safety shoes 100 are in the first state, the bottom surface of the first ventilation opening 30 is blocked by the upper surface of the first cap 10, and the left side surface of the first ventilation opening 30 is in contact with the front elastic member 12, And the right side surface portion may have a structure that is blocked by the first and second elastic members 22 and 26, the second cap 20, and the second jacket 28. As shown in FIG.

In this case, even if the water W flows into the first ventilation opening 30, the first ventilation opening 30 is surrounded by the above-described structures, so that the flow of the water W into the safety opening 100 can be blocked.

Referring to FIG. 5, the second cap 20 may rotate (R) about the hinge 40 about the first cap 10. Specifically, the lower end of the second cap 20 can be rotated in a direction away from the bottom by using the foot muscle of the wearer's foot F while fixing the lower end of the first cap 10 to the bottom surface. That is, the state in which the middle part rotates with respect to the forefoot can be defined as the second state.

In the second state, air introduced into the first ventilation hole (30) can be introduced into the wearer's foot through the second ventilation hole (24).

At this time, the first ventilation opening 30 may provide a rotation clearance when the second cap 20 rotates with respect to the first cap 10. 5, when the second cap 20 rotates in a counterclockwise direction with respect to the first cap 10, the first vent 30 opens the second cap 20 Can be rotated.

The second cap 20 can be rotated to contact the first cap 10 because the first vent 30 provides a rotation clearance. When the second cap 20 is in contact with the first cap 10, pressure may be applied to the air A filled in the first vent 30. That is, the air (A) in the first ventilation hole (30) can be pressed by the rotation of the second cap (20).

Accordingly, the compressed air A can not be discharged to the outside due to the contact C, but can be introduced into the inlet D of the second ventilation opening 24. The air A injected into the second vent hole 24 can be supplied into the second cap 20 through the holes H1, H2 and H3 located at the lower end of the second vent hole. Accordingly, in the second state, the outside air A can be introduced into the safety shoes 100.

According to the embodiment of the present invention described above, since the tip end of the second cap 20 overlaps the rear end of the first cap 10 and the first vent 30 is provided on the upper surface of the first cap 10 , The problem that the water flows into the safety shoes 100 in the first state (non-rotating state) can be solved.

Further, when the second cap 20 rotates with respect to the first cap 10, the first vent 30 provides a rotation clearance, and when the second cap 20 rotates, The air A in the first ventilation opening 30 is naturally compressed and can be introduced into the safety ventilation opening 100 through the second ventilation opening 24 because the opening of the ventilation opening 30 is blocked. Therefore, the fit feeling of safety can be improved naturally.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
