Description

Shoes support foam {Shoes support foam}

The present invention relates to a shoe insertion type size adjuster, and more particularly, to a shoe insertion type size adjuster which is capable of minimizing the pressure exerted on the toe by flexing the elastic portion and simultaneously expanding the extension portion when the foot is stepped on the ground, And a shoe insertion type size adjuster for preventing the shoe from being peeled by quickly supporting the toe by restoring the shoe part and the extension part at the same time.

In general, shoes are designated by a certain size and released uniformly, and consumers are choosing shoes that are closest to the foot size among the released products.

However, when a child grows fast, the shoes become smaller even after several months if they buy the shoes that fit the size of the foot. Even in the case of adults, the size of the foot at the evening when the feet are overloaded due to various activities in the morning becomes larger.

When you wear the same shoes in this situation, the tip of the toe can be pushed into the shoe, and in severe cases, it may develop into a malignant disease such as a resistant claw.

In particular, women's high heels that pursue beauty have narrow balls, high pelvic areas and high heels, so that the load of the body is pushed to the front of the shoe and the toes are pressed, resulting in extreme fatigue as well as hallucination and scarring when worn for a long time .

In order to solve such a situation, when shoes having a size larger than the size of the user's feet are purchased, the shoes are peeled off when the user treads the shoes.

In order to solve this problem, there has been developed a member for adjusting the size by putting foam such as latex or sponge on the back cushion or toe of the shoe. However, when the user wears the shoe, However, there was still a problem that the shoe was peeled off because it could not respond quickly to the change in the size of the foot when the foot came off the ground again, such as when walking or running.

In addition, a method of injecting air by an air pump by placing an inflatable air pack in front of the shoe was developed, but it was difficult to use air because it was very cumbersome to inject air.

Therefore, shoes which can prevent the shoe from peeling off during the actual movement by suitably maintaining the pressure between the toe and the shoe by rapidly responding to the change of the size of the foot when the foot is released from the ground without giving a load to the toe when worn, It is necessary to develop an insertion type size regulator.

FIG. 5 is a plan view of a shoe insertion type size adjuster according to an embodiment of the present invention. FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, the shoe insertion type size adjuster of the present invention includes a body 100 having a curved shape toward the front side and a body 100 having a shape extending in the front direction from the upper and lower ends of the front side of the body 100 And an elastic portion 110 and a plurality of extension portions 120 formed on the upper or lower surface of the body 100 or the elastic portion 110 so as to be recessed in the forward and backward directions.

The body 100 is formed into a bar shape curved toward the front surface. That is, it has a thick feeling and has a curved shape so that it can be inserted into the toe end portion of the shoe closely.

It is preferable that the body 100 is formed so as to be very thin at both ends compared to the middle portion so that both ends are brought into close contact with both sides of the shoe so as to avoid a feeling of being caught in the ignition.

The body 100 is made of rubber, latex, silicone, sponge, or similar elastic and expandable synthetic resin material, so that when the tip of the toe touches the rear surface of the body 100 by wearing shoes, Or in the lateral direction so as not to press the toes extensively.

At the top and bottom of the front of the body 100, the elastic part 110 is extended toward the front direction.

In addition, although the body 100 may have the same length as the inner side of the shoe and the outer side, it is preferable that the length of the outer side is longer than that of the shoe inner side. This is because the outer part of the shoe, which ends at the toe than the inner part of the shoe which ends at the big toe, is longer at the front of the shoe.

The elastic part 110 increases elasticity of the body 100 to increase the adhesion when the shoe is worn and reduces the pressure applied to the toes. The elastic part 110 is extended from the upper end and the lower end of the front face of the body 100 .

The elastic part 110 is formed of the same material as the body 100 and is integrally formed with the body 100. The elastic part 110 is described separately from the body 100 for the description of the invention, They are not formed by mutually combining different structures. However, it is not excluded that the two structures are formed by mutual bonding.

The elastic part 110 is formed in a shape of a piece and extends from the upper end and the lower end of the front side of the body 100. The elastic part 110 is spaced apart from each of the extended elastic parts 110, . The elastic portion 110 is bent downward or upward so that the ends of the elastic portion 110 are opposed to each other, and when the body 100 is pressed forward, the end portion of the elastic portion 110 is inwardly And absorbs the pressure. When the pressure applied to the body 100 is released, the body 100 can be quickly retracted backward.

The elastic portion 110 may be formed in the center portion of the body 100 in the same manner as the body 100 in order to facilitate the close contact with the inner side of the shoe and to minimize the foot of the body 100 by the elastic portion 110, It is preferable that the portion is formed in a shape that is wide and becomes narrower toward the end portion of the body 100.

The extension part 120 is formed in a groove shape in a direction perpendicular to the longitudinal direction of the body 100 on the upper surface or the lower surface of the body 100 or the elastic part 110. The body 100 or the elastic part 110 is formed to be recessed in the front or rear direction on the upper surface or the lower surface of the body 100 or the elastic part 110 to easily expand the body 100 or the elastic part 110 in the left and right directions.

When the body 100 or the elastic part 110 receives the pressure in the forward and backward directions, it also extends to the left and right sides. At this time, the extension part 120 is formed to facilitate the expansion to the left and right sides.

In other words, the size of the foot increases when the user wears the shoe while walking on the floor. At this time, the elastic force is stored by the elastic part 110 and the elastic force is stored by the extension part 120 by the second order, The foot is restored when the foot of the foot falls off the ground, so that it is possible to recover a quick elasticity even when wearing a somewhat larger shoe, thereby supporting the toes and thereby preventing the shoe from being peeled off. In addition, the body 100 can be more easily advanced due to the double elastic storage structure of the elastic part 110 and the extension part 120, and thus the pressing force applied to the toe when the user's foot is lifted So that it can be minimized.

According to the use state of the present invention constructed as described above, the shoe insertion type size adjuster of the present invention is pushed into the inside of the shoe. At this time, the elastic portion 110 is brought into close contact with the innermost portion of the shoe. As shown in FIG. 4, when the foot is pushed into the shoe, the tip of the toe comes into close contact with the rear surface of the body 100. When the foot is then moved to the ground, the foot is pushed and the toe is pushed forward. At this time, the body 100 and the elastic part 110 are extended as shown in FIG. At the same time, the elastic portion 110 is bent inward as shown in Fig. When the foot is released from the ground, the elastic portion 110 is restored and the body 100 is pushed backward, and at the same time, the enlarged portion 120 is also contracted to quickly push the body 100 backward.

In the drawings of the present invention, the pressure applied to the tip of the toe is stronger than that of the other shoes. However, since the feet of the human are arched when the feet are placed on the ground and when the feet are released from the ground, It goes without saying that the present invention is not limited to the embodiment shown in the drawings but can be applied to any shoes.

Therefore, the shoe insertion type size adjuster of the present invention having the above-described structure can reduce the pressure applied to the toes by flexing the elastic portion 110 and expanding the expanding portion 120 when the foot is put on the ground, .

In addition, the shoe insertion type size adjuster of the present invention has the effect of preventing the shoe from being peeled off by quickly supporting the toe by restoring the elastic portion 110 and the extension portion 120 simultaneously when the foot is released from the ground.
