Description

A shoe capable of an opening and closing of a ventilation hole}

The present invention relates to a shoe that can open and close the ventilation hole, and more particularly to a shoe that can open and close the ventilation hole to properly block the inflow of foreign matter into the ventilation hole.

In general, shoes were created for the purpose of protecting the feet, but with the change of times and fashions, the design and function have changed. Emphasis was placed on most shoes to emphasize breathability and drainage, and even shoes that emphasize safety.

Recently, as a part of preventing and / or treating foot odor, eczema and athlete's foot, the development of technology to keep the inside of the shoe clean through the introduced air by introducing fresh air into the shoe Coming. For example, shoes are manufactured using an upper (or outer shell) made of a material having good ventilation, or shoes are manufactured using an upper having a vent hole.

However, the conventional ventilation methods as described above are insignificant and do not obtain satisfactory results. Moreover, since the sweat of the foot is most generated by heat generated by friction with the bottom when walking between the sole and the toe, it is difficult to remove the heat and moisture generated from the foot without fundamentally solving it.

Accordingly, the present applicant is February 13, 2004 (Application No .; 20-2004-0003639), the circulation of air in the shoe is smoothly made, the heat and humidity inside the shoe is adjusted to a good condition to make the inside of the shoe pleasant As of January 31, 2005, claims relating to shoes were filed by filing soles and shoes with an air circulation function that can be kept in a state.

Particularly, according to the application number 20-2004-0003639, by making a ventilation groove to have an upward slope toward the inner direction, water or soil and other foreign matters can be blocked as much as possible through the ventilation hole, and water or soil, When other foreign matters are introduced, the naturally introduced water or foreign matters are discharged without installing a separate device.

However, since the shoe of the application No. 20-2004-0003639 does not have a blocking means for blocking the ventilation holes, it is not possible to block the inflow of unnecessary contaminants such as water, soil, and other foreign substances. Accordingly, the soil or other foreign matter may enter through the vent hole and remain, and when passing through a place where water is standing, such as a puddle, the soil may flow into the vent groove through the vent hole and remain. This can lead to the worst case where the ventilation grooves and / or the ventilation holes are blocked and air circulation cannot be achieved.

The present invention has been proposed to solve the above problems, and provides a shoe that can open and close the ventilation hole to selectively block the foreign matter, such as water or dust flowing into the ventilation hole by selectively opening and closing the ventilation hole. Has its purpose.

When walking, the heel part first touches the ground, and pressure is applied to the rear part of the shoe so that the rear part of the sole 10 contracts first, so that the air present in the aeration 10 of the sole 10 (12; 12a, 12b) It is discharged to the outside through the vent hole 16 located at the rear of the (10). At this time, since the pressure is not applied to the toe portion, the contracting operation of the sole 10 is not made, and thus air is introduced into the air passage 12 through the vent hole 16 located at the front of the sole 10. On the contrary, when the load of the body is transferred from the heel to the toe (that is, when it is moved forward), the air inflow is performed at the rear of the sole 10, and the air is discharged at the front.

That is, the sole cover 30 is contracted by the pressure of the sole when the foot treads on the ground due to the bending and pressure difference naturally generated during walking. Accordingly, the air introduced into the air passages 12 (12a, 12b) through the vent hole 16 of the sole 10 is discharged to the outside through the vent hole 16 by the contraction of the sole 10. On the contrary, when the foot is lifted, the sole 10 is restored to its original state, and air is introduced through the vent hole 16 of the sole 10. In this way, the inflow and discharge of the air is made repeatedly to smoothly circulate the air inside the shoe and keep the state inside the shoe in a comfortable state. This air inflow and outflow operation can be regarded as the same as described in the sole and the shoe (application number; 20-2004-0003639) having an air circulation function filed by the applicant of the utility model registration.

On the contrary, when passing through a pool of puddle or dust where water is accumulated, the vent hole opening and closing means 40 which is currently inserted in the second strip groove 18 is removed from the second strip groove 18. After that, it is inserted into the first band groove 14 as shown in FIG. That is, the projections 42 of the ventilation hole opening and closing means 40 are inserted into the ventilation holes 16 in the first band groove 14, respectively. Branch vent passage 12b communicated with the vent hole 16 has an ascending inclined structure of about 4 degrees to 10 degrees, but because the material of the vent hole opening and closing means 40 is a material having elasticity and restoring force, the protrusion ( 42 is inserted into the vent hole 16 without any difficulty.

Since the plurality of vent holes 16 are closed while passing through a lot of puddle or dust after doing this, foreign matter such as water or dust passes through the vent holes 16 through the vent holes 12; 12a. 12b). On the other hand, since the plurality of vent holes 16 are closed, the air introduced into the vents 12a and 12b before the plurality of vent holes 16 is closed may serve as a cushion.

Then, after inserting the ventilation hole opening and closing means 40 into the first strip groove portion 14 and completely passing through a lot of puddle or dust, the ventilation hole opening and closing means 40 is again returned to the first strip groove portion 14. Remove from and insert into the second belt groove 18. Then, the inflow and exhaust of the air is made repeatedly as usual, so that the air in the shoe is smoothly circulated and the state of the shoe is kept in a comfortable state.
