Description

Midsole used in manufacturing shoes with ventilation function {MIDSOLES FOR SHOES EQUIPPED WITH VENTILATION}

The present invention relates to a midsole used when manufacturing a shoe having a ventilation function, and specifically, in a shoe including a midsole through which air communicates with the outside of the shoe, external air is introduced through the midsole to allow the body and the midsole of the shoe. Air is introduced into the interior and air is discharged when walking, allowing the air in the shoes to circulate continuously, while these midsoles have a cushioning function, one of the main functions of the midsole, and have more abrasion resistance properties. It is related to the technology for the midsole used in the manufacture of shoes with ventilation functions that extend the possible life span and include antibacterial functions so that shoes can be worn in a more comfortable state.

In general, shoes are clothes worn on the feet and have a function of blocking and protecting the feet from the outside at the same time. In addition, depending on the function, it provides warmth and helps physical activity.

Shoes may have different structures depending on their function or use, but in general, the body and the sole with the outer skin of the shoe are basically equipped, and it is one of the important parts in highlighting the fit of the shoe or the functional part of the shoe. Is the sole. If these soles are subdivided, they can be further specified as insoles, midsoles, and outsoles.In particular, midsoles are mainly included in sneakers to maximize fit and maximize activity. It is an element with Therefore, in developing the functionality of sneakers in shoes, in particular, in order to maximize the function of the midsole, various techniques have been proposed in the prior art.

Meanwhile, in the following description, some of the components are omitted or excessively enlarged or reduced in order to describe the functions of each component of the present invention, but the corresponding figures are the technical features and rights of the present invention. It will be understood that it is not intended to limit the scope.

In addition, in the following description, a plurality of drawings will be simultaneously referred to and described in order to describe one technical feature or constituent elements constituting the invention.

1 is a side view of a midsole used when manufacturing a shoe with a ventilation function according to an embodiment of the present invention, and FIG. 2 is a side view of a midsole used when manufacturing a shoe with a ventilation function according to an embodiment of the present invention. It is an example of a region in which the first air flow path or the second air flow path is included in the midsole, and FIG. 3 is a midsole worn by a user when manufacturing a shoe with a ventilation function according to an embodiment of the present invention. It is a diagram showing the principle of the inflow or discharge of air when walking behind the back, and FIG. 4 is a diagram showing a cushion member included in the midsole included in the midsole used when manufacturing a shoe with a ventilation function according to an embodiment of the present invention Yes.

Referring to the above drawings together, in general, a shoe includes a body 10 and a sole including the outer skin of the shoe, but the shoe worn when more activity is required mainly further includes a midsole 20 together. do.

Specifically, referring to Figures 1 and 2 together with the shoe including the midsole 20 provided with a ventilation function in the present invention, the present invention provides an outsole 30 in contact with the ground and a user's foot It is for the midsole 20 included between the body 10 of the shoe so that the outer skin covers the foot, except for the opening for allowing the shoe to be worn.

In general, shoes may include a variety of configurations depending on their use, and the shoe as a simple configuration is the outsole 30, which is a thin window at the bottom of the ground contacting the above-described body 10 in which the outline of the shoe is specifically revealed. Can be made of. However, the midsole 20 may be further included in the type of sneakers that are mainly worn when activity is required depending on the user.

The conventional midsole 20 is a configuration mainly aimed at absorbing or reducing shock. The midsole 20 is further included to maximize the fit of the shoe, and in particular, through the midsole 20 with a reinforced cushioning function, activity when wearing the shoe can be maximized.

In the present invention, when the midsole 20 mainly requires activity, for example, as it is included in the shoes of athletic shoes used for sports or outdoors, it is included in one area of the midsole 20 to provide external air. As is introduced, while being connected to the first air flow paths (A, B) and the first air flow paths (A, B) formed so that the external air that is introduced by being connected to the body 10 also flows inside the body 10 It is configured to include second air flow paths (C, D) through which air flows inside the midsole 20, so that ventilation is increased first and the inside of the shoe is kept dry.

Referring to the drawings, FIG. 2 shows an example of a region in the midsole 20 in which the first air flow paths A and B or the second air flow paths C and D are included. Specifically, the above-described first air flow paths A and B are formed in at least one or more regions of the midsole 20 except for a region in which the foot load is applied relatively heavier when the user wears shoes. That is, the first air flow paths A and B may be included in the area A or B in (20a) of FIG. 2.

The reason why these first air flow paths (A, B) are included in the region where the load of the foot is relatively less heavily applied is through the first air flow paths (A, B) included in one region of the midsole 20. This is to ensure that the air is continuously introduced as outside air is introduced. Specifically, when the user wears shoes, the user's load is carried on the foot, and accordingly, when a load is applied to the shoe, the midsole 20 or the outsole 30 area of the shoe is also pressed. At this time, the first air Since the space occupied by the flow paths A and B may be reduced, external air is relatively difficult to inflow due to pressure or the like. Accordingly, in order to enhance breathability, the first air flow paths A and B may be mainly distributed in the A region B region where the foot load is relatively less. Through this, air can be continuously introduced through the first air flow paths A and B.

Of course, in addition to the above-described first air flow paths (A, B), it is possible to maximize a breathable function for continuously drying the inside of the body 10 by further including a separate ventilation hole.

Therefore, by including the first air flow paths (A, B) through which the air and the outside of the shoe can flow in the midsole, air is introduced or discharged into and out of the shoe, thereby providing a ventilation function to the shoe, thereby ensuring that the shoe is dry. It has the effect of removing moisture due to sweat generated while the user wears the shoes by maintaining the shoes so that they can wear the shoes in a comfortable state.

On the other hand, the above-described second air flow paths C and D are formed in at least one or more regions in which the load of the feet is relatively heavier than the other regions among one region of the midsole 20 when the user wears shoes.

This is to allow air to flow inside the midsole 20 in the second air flow paths C and D, and thus may be included in the region C or D in FIG. 2 (20b). Specifically, unlike the first air flow paths A and B, the second air flow paths C and D are not directly circulated with the outside of the shoe, so the inside of the midsole 20 is the same as the pump. It is to make air flow. In other words, the second air flow path (C, D) is included in the area where the foot load is strongly applied, so that it receives the load from the foot sufficiently to push the air out by the pressure applied to the second air flow path (C, D), and then again as a pressure difference. This is to allow air to be introduced through the first air flow paths A and B.

The first air flow paths A and B or the second air flow paths C and D described above may be included in the midsole 20 in various forms. As an example, it may be in the form of a plurality of air chambers or a configuration such as a hole, and may take the form of a mesh, etc. In the present invention, if the above-described functions are possible configurations or materials It is possible to use without limitation, and according to another embodiment, the first air flow paths A and B and the second air flow paths C and D may be formed of different configurations or materials.

Therefore, a shoe structure is mounted on the upper surface of the midsole 20 through the first air flow paths (A, B) and the second air flow paths (C, D), so that when the user wears shoes and walks, the outsole 30 is When a load is applied by the user's foot to the midsole 20 in contact with the ground, the body 10 or the midsole 20 is passed through the first air flow path (A, B) or the second air flow path (C, D). ) When the internal air is discharged to the outside of the shoe and the load by the user's foot applied to the midsole 20 becomes relatively weak as the outsole 30 falls from the ground, the first air flow path (A, B) Alternatively, air is introduced into the body 10 or the midsole 20 through the second air flow paths C and D.

That is, FIG. 3 shows the above-described principle of inflow/exhaust air, (a) shows that when the user wears shoes and walks, air is discharged at the moment when the outsole 30 contacts the ground, ( b) shows that when the user walks while wearing shoes, air is introduced into the midsole 20 at the moment when the outsole 30 falls from the ground. In detail, as shown in (a), when the user's load is applied to the area of the midsole 20, the pressure applied increases, so the air inside the midsole 20 or the body 10 is discharged to the outside of the shoe. As shown in (b), when the ground and feet fall, the user's load on the midsole 20 is relatively weak, so the applied pressure is also relatively low, and the pressure that was increased at the point in (a) decreases. As a difference occurs, external air is introduced into the midsole 20 or the body 10.

That is, as described above, by allowing air to flow inside the midsole through the second air flow paths (C, D), the effect of further maximizing the breathability of the shoes together with the first air flow paths (A, B). There is.

In addition, the midsole 20 includes a cushion member 21 at a lower portion of the heel of the foot where the user's heel abuts.

The midsole 20 is generally used mainly for cushioning or absorbing shock, and may further include a cushion member 21 to enhance the function of the original midsole 20 in the present invention. As the cushion member 21 described above, materials such as thermoplastic polyurethane (TPU) foam, polyurethane (PU), and EVA (Ethylene-Vinyl Acetate) may be used, and in addition to this, one or more empty spaces to further maximize the cushioning feeling. By adding more, it is possible to further alleviate the impact when pressed by the user's load by using together with the above-described cushion member.The present invention includes a cushion member and, as another example, further provides a shock mitigation function as a structural element. Can be maximized.

In addition, the above-described midsole includes at least one material having an antibacterial function.

For example, polyester-based, acrylic, cellulose-based (natural), polyamide-based, polypropylene-based, polyurethane-based, other alginic acid, PVA, nylon, polyacrylic, polyolefin, etc. In use, these materials may be made of a single material or may be mixed between materials, and of course, it can be understood that they may be mixed with the above-described cushion member 21.

By further including the above-described antibacterial function, the occurrence of germs due to moisture, etc. that may be generated inside the shoe is suppressed so that the user wears the shoe in a more comfortable state when the shoe is worn, thereby removing foot odor or It is possible to increase hygiene when worn, and this function is further combined with the midsole 20 of the present invention to maximize breathability, so that there is little smell inside the shoe along with a dry feeling when using the shoe.

In addition, when the user wears shoes, the midsole 20 is coated with an abrasion-resistant material in one or more regions of the midsole 20 in which the load of the foot is relatively heavier than the other region.

This is a configuration in which the midsole 20 is mainly included in footwear (sneakers, etc.) with strong activity, and the speed at which the shoe wears out will be relatively faster than other footwear as it has a lot of activity. It is to slow it down. As an example of a material for preventing wear, Teflon (PTFE) may be used, and it may be coated with organic molybdenum (AOMC) having a function similar to that of a protective film that can be used when preventing engine wear, as well as self-healing It may further include fibers having performance, or may be coated with a material obtained by liquefying fibers having such self-healing performance. Or, instead of coating, you could add a material that does not wear well. Of course, it will be preferable that the above-described coating area is mainly coated on an area where a load by the user's foot is applied relatively more strongly.

Therefore, while reinforcing the original function of the midsole by reinforcing the original function of the midsole by using the above-described functions, i.e., a cushion function, to reduce the impact when wearing shoes, the midsole of the present invention may be included in the shoes mainly used when the activity is high. In some cases, the shoes are not easily worn through the abrasion resistance properties of the shoes, and by including an antimicrobial material together, there is an effect that the shoes can be used more comfortably with a breathable function.

Meanwhile, when the user wears shoes, the midsole 20 may further include a material in which the load of the foot changes to one or more different colors according to the magnitude of the pressure applied to one area of the midsole 20.

A material that changes to one or more different colors depending on the pressure level described above is, for example, a composite polymer material composed of polydimethylsiloxane (PDMS), and is easily colored according to external pressure by coating silica nanoparticles with high mechanical strength in a porous film. Materials similar to this changing artificial skin could be used. For example, in the above-described material, as the intensity of the pressure increases, the purple color becomes darker, or the shape of the color change may be changed according to the shape of the object to which the pressure is applied. For example, when pressure is applied to a square object, it may turn purple into a square shape. Of course, in the above-described example, the intensity of the pressure is determined by a darkening color of purple, but depending on the material, the pressure is changed to a completely different color according to the pressure, so that the intensity of the pressure can be classified according to the color.

To further include the above-described material, it is considered that regions of the midsole 20 to which more pressure is applied may be different depending on the user. In other words, users may have different areas where pressure is applied to the soles of the feet according to their walking habits, body shape, etc., and areas where pressure is applied to the feet according to the user through the above-described material of the midsole 20, or in particular, pressure This more strongly applied area can be visually identified so that the user can grasp the walking posture, and thus can be used for gait correction or test.

As described above, although the embodiments have been described by limited embodiments and drawings, those of ordinary skill in the art will understand that various modifications and variations are possible from the above description. The terms such as "include", "consist of" or "have" described above mean that components without a description to the contrary may be included, so other components are not excluded. It should be construed as more inclusive. In addition, the scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the present invention.
