It's about.

In general, shoes are divided into those with laces and those without laces. At this time, it is necessary to prevent the shoes from coming off when walking. Considering stability, activity, and health after wearing the shoes, it is important to choose shoes that fit perfectly to the feet when walking. Because this is desirable, it is necessary to select shoes of the appropriate size for the wearer.

In particular, shoes with laces have straps that are tightened to fit the foot perfectly when walking. These shoes have an upper surrounded by a shell at the top of the outsole to secure space for storing the foot on the inside, and an upper to protect the top of the foot. It consists of a shoe tongue and a connecting ring or hole for connecting binding strings to both sides of the shoe tongue to enable tightening.

When wearing shoes with this configuration, the foot is inserted into the upper, then the binding string connected to the link or hole formed on both sides of the tongue of the shoe is pulled and tightened, and then tied to secure it. Conversely, when taking off the shoe, the tied strap is tied. The shoe is loosened by unscrewing it, and then the foot is pulled out from inside the upper.

However, using tie strings not only causes the inconvenience of having to repeat the process of tightening the tie straps of the shoes by hand, then tying them, and then loosening them, every time the shoe is taken off and put on, but also when walking or cantering while wearing the shoes. There is an inconvenient problem in use because the knot loosening occurs frequently.

As an example of prior art to solve this problem, in Korean Patent Publication No. 2011-0119904, the airbag means expands according to the operation of the push pump that occurs when the wearer walks, making the sole and toes more comfortable and stable. A pump-type airbag mechanism for shoes that provides support and shoes equipped with the airbag mechanism have been proposed.

At this time, when a chin (not shown) is formed protruding outward from the top of the outer circumferential surface of the exhaust pipe 113 so that the inner circumferential surface of the support plate 121 is located below the chin, the dial member 120 is separated from the fixed housing member 110. You can prevent it from happening.

The elevating housing member 130 is provided to enable the dial member 120 to be raised and lowered when the ignition operator operates the dial member 120. A screw thread is formed on the outer peripheral surface and an external screw tube 131 is screwed to the internal screw tube 122 of the dial member 120. ) and a cover plate 132 that closes the upper end of the external threaded pipe 131.

The flexible member 140 is made of a material with elasticity and elasticity, such as silicon or rubber, and is an element capable of opening and closing the main exhaust hole 111. It is installed on the lower surface of the cover plate 132 and serves as a lifting housing member 130. ) moves with.

With this structure, when the ignitioner rotates the dial member 120 to raise the lifting housing member 130 as in the state of FIG. 2, the flexible member 140 rises together and the lower end of the flexible member 140 and the exhaust pipe 113 ) A gap is formed at the top, and in this case, the air charged in the air bag 10 is discharged to the outside through the gap via the main exhaust hole 111.

Conversely, as in the state of FIG. 3, when the ignitor reversely rotates the dial member 120 to lower the lifting housing member 130, the flexible member 140 is lowered together and the lower end 141 of the flexible member 140 and the exhaust pipe ( By closely contacting the upper end 112 of 113), the main exhaust hole 111 can be closed to block air discharge from the air bag 10.

In addition, as in the state of FIG. 4, when the ignitor arbitrarily rotates the dial member 120 to raise or lower the lifting housing member 130, the lower end 141 of the flexible member 140 and the upper end of the exhaust pipe 113 ( The interval between the airbags 112) can be freely adjusted, and accordingly, the ignitor can set the amount of air discharged from the airbag 10 to maintain the internal pressure of the airbag 10 at the set pressure. That is, air can be discharged only when the internal pressure of the air bag 10 is higher than a set pressure, and for this purpose, the flexible member 140 can be designed to have an elastic force that functions like a spring (see FIG. 5).

In order for the flexible member 140 to have elastic force, as shown in FIG. 5, the flexible member 140 has a main body portion 142 whose lower end 141 opens and closes the upper end of the main exhaust hole 111. The wing portion 143 extends upward from the upper edge of the main body portion 142, and the upper end of the wing portion 140 contacts the lower end of the cover plate 132.
