In walking, each type of movement appears from our ankles to our feet at every gait cycle.

In general, the walking cycle of a normal person is as follows.

The initial folding device is also called a heel contact phase, which is the first step in the gait cycle, when the foot of the reference foot first touches the ground, and the heel touches the ground first. At this time, the angle from the outside of the heel touches the ground, and the foot is too unstable at that angle to support the weight, and the muscles can not support the entire weight with the feet tilted at that angle. So there are two possibilities for the foot to go outward or backward: the normal foot goes inward until it is flat on the ground, which is the pronation. If the foot goes out, it is called supination, and if the foot does not stop and continues to go out, then over-pronation occurs, resulting in an ankle sprain in the flat feet. In other words, the pivoting of the heel to the ground, ie the pivoting after the heel folding, allows the feet to lie flat on the ground and to support the entire body weight.

The mid-stance is also called foot flat phase. It refers to the period after the initial folding and the next step, when the foot of the reference foot is supported horizontally on the ground while supporting the load on the foot. The foot counseling helps balance your body by allowing your feet to adapt immediately to the ground, whatever the surface of the ground. In addition to the structure of the relaxed bones, the foot absorbs the shocks better.

The Heel Off Phase refers to the time when the heel, which was touching the ground, was heard on the ground. The foot must act as a leverage to move the body forward, by acting as a leverage by turning the foot outward, ie by supination. This swallowing allows the joints and bones to be firmly fixed, making their feet firm and ready for propulsion.

The propulsion (Toe Off Phase) is the last stage of the stance phase where the reference foot is in contact with the ground. Foot clearance occurs for smooth advancement. The knee joint is bent and the ankle joint I will. The toe lifter means that the toe pushes the ground and moves forward.

The swing phase is a period in which the base of the foot is separated from the ground while exercising the swing phase.

In other words, the walking cycle is carried out in the order of the heel folding device, the sole folding device, the heel lifting device, the toe lifter, the swinging device, and the heel folding device in the order of the heel folding. At the moment the heel lifting is started, the abduction occurs, and the toe pushes the ground at the toe lifter and moves forward, and our feet repeat this action.

Walking Running The most significant influence on mobility during exercise, such as long jump, is the heel lifter and the toe lifter that can hear the heel.

1 to 4, an air circulation insole according to an embodiment of the present invention includes an insole main body 100 and an insole air circulation unit 200. The insole body 100 includes an insole air circulation unit 200, And the flow path formed in the insole air circulation unit 200 is pushed while air is discharged toward the forefoot while the body weight is moved from the heel to the foot sole to the forefoot.

The insole body 100 is formed in a shape corresponding to the bottom of the shoe, and is laid on the inside of the shoe.

The insole body 100 may include a fabric made of fabric and a pad made of a foam having a cushion.

The insole air circulation part 200 is formed of an elastic material in whole or in part on the upper surface, the lower surface or the inside of the insole body 100, and a plurality of flow paths are formed in the longitudinal direction from the heel to the forefoot direction . (tube)

The insole air circulation unit 200

(See Fig. 2), the heel side channel is blocked by the weight on the heel side, and the heel side channel is switched to the soles of the foot so as to weight the foot side, The air inside is pushed out. At this time, since the heel side channel is blocked, the air is pushed to the forefoot side.

In the same manner as described above, air is pushed out to the forefoot side when the heel lifter (see Fig.

That is, while the body weight is moved from the heel to the foot to the forefoot, the flow path formed in the insole air circulation unit 200 is pushed and air is discharged toward the forefoot.

In other words, when the massage formed in the insole air circulation unit 200 is performed in the order of the heel, sole, football, and toe, the air is sucked from the heel side and discharged to the forefoot side.

1 to 4, the insole air circulation unit 200 is provided on the upper surface of the insole body 100. However, the present invention is not limited thereto,

The weight of the heel to the forefoot through the heel, the soles of the heel, and the soles of the heel, which are all or part of the insole air circulation part 200, It is needless to say that any configuration is applicable as long as the flow path formed in the insole air circulation unit 200 is pressed while air is being discharged in the direction of the forefoot.

1 and 5, the insole air circulation part 200 of the air circulation insole according to the embodiment of the present invention includes a plurality of flow paths arranged in a width direction, The convexly formed portion having no flow path is concave and the thickness between the flow path and the flow path is smaller than the thickness of the portion where the flow path is formed.

In other words, a plurality of mountains and valleys are formed successively, mountains are formed at the portions where the flow paths are formed, and valleys are formed at portions where the flow paths are not present.

This is for the purpose of facilitating the deformation of the portion where the flow path is formed, so that the envelope surrounding the flow path where the body weight is loaded is deformed to block the flow path.

At this time, the cross-sectional shape of the flow path is preferably circular. This is also intended to facilitate the deformation of the flow path, and to facilitate the deformation of the envelope surrounding the flow path and the blocking of the flow path.

For example, if the cross section of the flow path is circular and the upper and lower surfaces of the insole air circulation part 200 are formed in a straight line, the outer surface of the portion where the flow path is not present becomes thick, and the shape deformation can be relatively reduced. As a result, the part of the flow path between the flow path and the flow path may not be sealed. In this case, the air circulation efficiency using the deformation of the flow path is lowered.

Therefore, in the cross-sectional shape in which the plurality of flow paths are arranged in the width direction, the portions where the flow paths are formed are convex, the portions where the flow paths are not present are concave, and the thickness between the flow paths and the flow path is smaller than the thickness So that the flow path can be easily clogged by the weight.

5, the insole air circulation unit 200 has a plurality of flow paths arranged in parallel in the width direction. However, the present invention is not limited thereto, and the shape of the insole body 100 may be bent in an ergonomic shape, And may be arranged in a curved shape along the shape of the insole body 100.

As shown in FIGS. 1 and 6, the insole air circulation unit 200 of the air circulation insole according to the embodiment of the present invention is configured such that a plurality of tubes are connected in a width direction.

At this time, it is preferable that the tube has a donut shape in sectional shape.

This is also intended to facilitate the deformation of the flow path, and to facilitate the deformation of the envelope surrounding the flow path and the blocking of the flow path.

6, the insole air circulation unit 200 has a plurality of flow paths arranged in parallel to each other in the width direction. However, the present invention is not limited thereto, and the shape of the insole body 100 may be bent in an ergonomic shape And may be arranged in a curved shape along the shape of the insole body 100. FIG.

In addition, although FIG. 6 shows an example in which the cross section of the tube has a donut shape (circular shape), the present invention is not limited thereto, and may be an elliptical shape or a long elliptical shape.

In addition, although FIG. 6 shows an example in which the tubes are connected to each other, the present invention is not limited thereto, and various arrangements such as being spaced apart from each other are possible.

When the insole air circulation unit 200 pushes the air from the heel side to the forefoot side while putting the weight in the order of the heel, the sole, the football and the toe, the insole air circulation unit 200, If both the suction side and the discharge side inlet of the compressor are formed on the floor, there is a problem that the supply of fresh air is not smooth.

7 to 8, the flow path of the insole air circulation part 200 of the air circulation insole according to the embodiment of the present invention is formed so that the heel side is connected to the insole body 100, May be formed to extend for a longer period of time.

In other words, if the heel-side flow path is extended longer than the insole main body 100 as shown in FIG. 7, if the air circulation insole according to the embodiment of the present invention is used in the shoe as shown in FIG. 8, Fresh air is sucked from the upper side of the heel side of the shoe so as to discharge fresh air to the forefoot side of the shoe, thereby creating a more pleasant and clean shoe internal environment.

The shape of the foot indicated by the dashed line in FIGS. 7 to 8 is shown to show the position of the foot for the sake of understanding, and shows the shape of the insole air circulation unit 200 when not depressed.
