The present invention relates to a shoe midsole that can be adjusted to the sole of the foot, and more specifically, the midsole is separated into two or more airbags, and the two airbags are connected to each other in a tunnel form by a connector, but inside the connector By installing a valve to control the flow of air on the user's sole, the shape of the midsole is deformed according to the shape of the sole when the sole is grounded and grounded, so that the sole is parallel to the ground, helping the user's walking and functional posture. It prevents various diseases caused by abnormal shape or shape of the foot and at the same time absorbs the shock applied to the foot, which contributes to improving the function of the midsole. Of course, the overall weight of the shoe can be reduced, and mass production at low cost is possible. It relates to a flat sole shoe midsole for adjustable so that you can use.

In general, any abnormality in the structure and shape of the foot in the human body causes imbalances and inconsistencies not only in the foot itself but also in the entire body, such as the ankle, knee, leg, waist, and upper body. Connected to the exercise chain, if one part of the function and structure defects will affect the overall structure of the body in a chain.

In other words, pain is not caused by a disease anywhere in the body, but is caused by posture, bone shape, structure, and torsion of bones. After that, the shoe insole has been specially manufactured and corrected according to the shape of the user's foot.

This method has been recommended and prescribed by a specialist in foot medicine as a treatment for severe cases of abnormality, and the characteristics of the body, including the feet, continue to grow or deform over a period of time, The factor is greatly influenced by the surrounding environment, and in particular, the foot grows in a closed space called a shoe, and thus has various degrees of deformation and various shapes unique to other body parts.

If you check the shape of the athlete's foot, you can see how many deformations occur depending on the surrounding environment or the degree of the function that is used mainly. When used, the degree of deformation causes more deformation than that of non-exercises, and even in general non-exercises, genetic deformation, accidental deformation, and growth deformation due to wrong wearing of shoes are also reported. Many are happening.

When the user feels discomfort or disease due to deformation of the foot, a special insole prepared by a doctor's prescription as described above is worn and supplemented, but it is not generalized to users due to inconvenience and relative high cost due to the multi-step process.

In particular, in the case of children and adolescents who are in the process of growth, there are inconveniences and inefficiencies that require special production of insoles every time shoes are changed. There is a problem that includes the severity of causing other diseases or, in severe cases, develop into disorders.

The present invention improves the cost and inefficiency in order to solve the above problems, so that the midsole is transformed into a complementary form according to the shape of the sole of the user, even if worn by any user, including the general public to provide a better fit and functionality It is to provide general shoes with a device to prevent foot growth.

In other words, the present invention is produced in the shoe (Midsole) located between the insole (Insole) and the outsole (Outsole) separated into two or more air bags, and the two air bags are connected to each other in a tunnel form by a connector, By installing a valve that controls the flow of air inside the connecting pipe, the airbag air of the first closing surface of the sole of the sole moves to the airbag that does not touch the surface, and the airbag that does not touch the surface is subjected to the inlet air pressure. The shape of the foot and the ground so that the shape of the user's sole and the ground plane of the two or more airbags constituting the midsole is equally complemented with each other.

Therefore, the midsole of the shoe according to the present invention is to help the user's walking and functional posture by making the sole of the foot parallel to the ground by complementing the shape of the midsole according to the shape of the sole when the sole surface of the user and the ground. It prevents various diseases caused by abnormal shape or shape of the foot and at the same time absorbs the shock applied to the foot, which contributes to improving the function of the midsole. Of course, it is possible to reduce the weight of the entire shoe, and to be able to use in general by mass production at low cost as a technical problem.

In the shoe midsole, the midsole is formed in the shape of the sole of the foot and is divided into two in the longitudinal direction and constitutes a soft first airbag and a second airbag having an empty internal space, and on one side of the first airbag, a cylindrical shape A first connector is formed, and a cylindrical second connector is formed on one side of the second airbag to be fitted inside the first connector to connect the first and second airbags to each other. A plurality of grooves are formed in the first and second airbags at regular intervals, and implants are installed in the grooves to prevent the entire midsole from falling down due to the user's weight, and a second connector formed on the second airbag. Inside, a discharge port is opened by air pressure, and a one-way valve is installed to supply air to the second air bag. Generated is characterized in that the other second connection pipe inside which claim to control the flow of air to both the first and second air bags either side two-way valve is installed in the inlet by a through hole.

A plurality of second connecting pipes 36a to 36d are formed inside the first connecting pipes 35a to 35d to connect the first airbag 31 and the second airbag 32 to each other.

2A, a plurality of grooves 33a and 33b are formed at the center of the first and second airbags 31 and 32 at regular intervals, as shown in the enlarged cross-sectional view of the AA line shown in FIG. 2A. Inside the grooves 33a and 33b, the implants 34a and 34b made of polyurethane (PU) or EVA material flow into the grooves so as to perform the basic functions of the softly made midsole 30. The whole midsole 30 is prevented from falling down.

In addition, as shown in the enlarged cross-sectional view taken along the line BB shown in FIG. 2B, the discharge port 40 is opened by the air pressure in the second connecting pipes 36a and 36c formed in the second airbag 32 so that the second airbag 32 is opened. One-way valves (37a) (37b) for supplying air only to the inlet is installed.

In addition, as shown in the enlarged cross-sectional view of the CC line shown in FIG. 2C, the second and third airbags 31b and 36d formed in the second airbag 32 are formed by the through holes 39. (32) Both sides of the cylindrical two-way valve (38a, 38b) that can control the flow of air is installed inlet.

Here, the one-way valve 37a (37b) is to open the discharge port 40 by the air pressure, the cylindrical two-way valve 38a (38b) is to control the flow rate of air in accordance with the number of the through-hole (39) Can be.

Referring to the assembly process of the sole midsole 30, which can be adjusted to the sole balance according to the present invention made as described above are as follows.

First, the implants 34a and 34b made of polyurethane (PU) or EVA material are inserted into and adhered to the recesses 33a and 33b formed on the first and second airbags 31 and 32. To maintain a constant height, and then the one-way valves 37a and 37b are introduced into and fixed inside the second connecting pipes 36a and 36c formed in the second airbag 32, and the cylindrical bidirectional valves 38a and 38b. To the other second connecting pipes 36b and 36d formed in the second airbag 32, respectively, the one-way valves 37a and 37b and the bidirectional valves 38a and 38b are connected to the second connection pipe ( 36a ~ 36d) By tightly fitting the inner surface with each other, the air is prevented from leaking to the outside.

At this time, the left and right correction direction of the sole is determined according to which direction the discharge port 40 of the one-way valve 37a (37b) is installed, which can be set arbitrarily in response to the sole state of the user, the present invention In the following description, the outlet 40 is installed to allow air to flow into the second airbag 32.

As described above, the second connecting pipes 36a to 36d are connected to the first airbag 31 while the one-way valves 37a and 37b and the bidirectional valves 38a and 38b are installed in the second connecting pipes 36a to 36d. When forced into and coupled to correspond to the inside of the first connecting pipe (35a ~ 35d) formed in the first and second airbag 31, 32 as shown in Figure 1b and 1c is connected to the first, second Through the pipes (35a ~ 35d) (36a ~ 36d) to each other is tightly coupled is made.

At this time, the air flows to both sides of the first and second airbags 31 and 32 by the bidirectional valves 38a and 38b, but the one-way valves 37a and 37b supply air only to the second airbag 32. Will be supplied.

Referring to the functional relationship in the state that is installed between the sole and the insole of the shoe midsole 30 can be adjusted according to the present invention assembled as described above.

That is, when the user walks, the sole of the foot is deformed or the ground surface is inclined, or when the inner part of the foot first touches the ground by the walking habit, the weight of the user is transmitted to the first airbag 31 as the first airbag 31. The air pressure filled therein is increased, and the air outlets of the one-way valves 37a and 37b are opened by the air pressure to supply air to the second airbag 32, thereby providing the second airbag (as shown in FIG. 2B). 32) The overall height rises and deforms to equilibrate with the earth's surface.

At this time, the air delivered to the second airbag 32 through the one-way valve (37a) (37b) does not flow back, and when the user continues to apply the force, respectively, the first and second airbag (31, 32) Is to continue to deform to the user's surface in the opposite direction of the sole of the foot, parallel to the surface.

In this state, when the user takes his foot off the ground to connect to the next walk, the pressure applied to the first airbag 31 is released, so that the movement occurs from a place where the air pressure is high to a low place and flows into the second airbag 32. Air flows through the through-hole 39 formed in the cylindrical bidirectional valves 38a and 38b to the first airbag 31 so that the first and second airbags 31 and 32 remain in their original states until the next stepping. Is restored.

At this time, the bidirectional valves 38a and 38b may be freely moved between the first and second airbags 31 and 32 through the through-holes 39 by air pressure. By adjusting the size and number of the through-holes 39 formed, it is possible to adjust the restoration speed of the deformed first and second airbags 31 and 32, due to the small air holes when deflating the conventional air tube. You can't let the air out at once, but if you leave the air holes open for some time, the same applies to getting out of high air pressure to low air.

As such, the present invention installs two first and second airbags 31 separated by the left and right sides of the sole of the shoe sole in the longitudinal direction of the shoe sole, and has a deformation of the airbag shape by the user's force. In addition, the deformed shape is deformed and complemented to the shape of the sole of the user so as to be parallel to the ground surface when the user walks the room to help the user's walking and functional posture.

Figure 3a is an exploded perspective view showing another embodiment of the sole midsole for shoe adjustment in accordance with the present invention, Figure 3b is a combined perspective view of Figure 3a, two first and second airbags 31, 32 It is divided into front and rear of the sole, and a plurality of first connecting pipes (35a) (35b) having a cylindrical shape is formed on one side of the first air bag 31, the first side on one side of the second air bag (32) Second connection pipes 36a and 36b are formed inside the connection pipe 35 to connect the first airbag 31 and the second airbag 32 so as to penetrate each other, and the second connection pipe 36a is formed. The one-way valve 37a and the two-way valve 38a are introduced into the 36b.

Another embodiment of the above is the same operation process as described above, it is possible to adjust the user's foot in parallel with the ground in the forward and rearward direction to allow correction according to the shape of the sole of the user.

In addition, in the present invention, the midsole 30 may be divided into four airbags before, after, left, and right as needed to more precisely adjust the balance of the foot, and the number of airbags is not limited.

As described above, the present invention separates and manufactures the midsole into two or more airbags, and the two airbags are connected to each other in the form of a tunnel by a connecting pipe, and a valve capable of controlling the flow of air inside the connecting pipe. When the sole surface of the user's sole is grounded and grounded, the shape of the midsole is supplemented according to the shape of the sole, so that the sole is parallel to the surface, which helps the user's walking and functional posture, resulting in abnormalities in the shape or shape of the foot. It prevents various diseases and absorbs the impact on the feet, which contributes to improving the function of the midsole and reduces the weight of the entire shoe. As a result, mass production at low cost is possible.
