This is an example of a schematic diagram in which an insole vent and a midsole vent are formed in a midsole with improved ventilation and antibacterial function and a shoe including the same.

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 30 together. do. Specifically, in the present invention, all of the insole 20, the midsole 30, and the outsole 40 are used as the sole so that the user can feel the elasticity and the cushioning feeling when walking.

Specifically, the midsole 30 with improved ventilation and antibacterial function in the present invention and a shoe including the same will be described with reference to FIGS. 1 and 2, and the present invention provides an opening that allows a user to put his or her feet on. Except for the midsole 30 included between the insole 20 in contact with the user's foot and the outsole 40 in contact with the ground, which is provided under the body 10 of the shoe so that the outer skin covers the foot.

In general, shoes may include a variety of configurations depending on their use, and the shoe as a simple configuration is the outsole 40, 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. It can be made of. However, the midsole 30 may be further included in the type of sneakers that are mainly worn when activity is required depending on the user.

The conventional midsole 30 is a configuration mainly aimed at absorbing or mitigating shock. The midsole 30 is further included to maximize the fit of the shoe, and in particular, through the midsole 30 having a reinforced cushioning function, activity when the shoe is worn can be maximized. Accordingly, the present invention maximizes the fit and activity by using both the insole 20, the midsole 30, and the outsole 40.

In the present invention, when the midsole 30 mainly requires activity, for example, as it is included in the shoes of athletic shoes used for sports or outdoors, the midsole 30 in the present invention in particular has air at the top. One or more midsole vents 33 formed to flow, and one or more regions of the edge of the upper portion 31 of the midsole protrude in a vertical direction with the ground, but one region of one side that does not contact the outside of the shoe is concave. It includes the formed insole fixing portion 34.

First, the midsole 30 of the present invention includes a plurality of midsole vents 33 to allow air to flow in a region between the insole 20 and the midsole 30. The addition of such a plurality of midsole vents 33 in the midsole 30 prevents moisture, odors, etc. that occur due to the user's walking while pressure is applied to the user's weight from the insole 20 where the user's feet directly contact. In addition to the insole 20, it gradually accumulates in the midsole 30, and the air is allowed to flow through the midsole vent 33 described above to relieve moisture or odor inside the shoe.

That is, the midsole 30 includes a plurality of midsole vents 33 that allow air to flow inside the shoe, so that the air is circulated inside the shoe at the user's weight pressure when the user walks, preventing air from staying. By providing the shoe to maintain a dry state, thereby increasing the breathability of the shoe, there is an effect that the user wears the shoe in a comfortable state by removing moisture due to sweat generated while wearing the shoe.

However, as described above, the contact area between the insole 20 and the midsole 30 when a plurality of midsole vents 33 are formed in the midsole 30 is compared to when the midsole vent 33 is not formed. Since it is relatively smaller, in the present invention, by providing an insole fixing part 34 more, this problem is solved.

Accordingly, when the above-described insole fixing part 34 is described with reference to FIGS. 2 and 3, the insole fixing part 34 is a region in which the edge of the midsole 30 or a part of the outline rim protrudes, and one surface of the shoe One area on one side of the opposite side that contacts the outside and may contact the user's foot inside the body 10 of the shoe may have a concave shape while another area may have a convex shape. Preferably, as shown, one region of the upper portion of the insole fixing portion 34 may have a convex shape, and one region of the lower portion may have a concave shape.

More preferably, the above-described insole fixing part 34 is, as shown in FIG. 4, the heel part where the user's heel abuts at the edge of the midsole 30, the forefoot part where the heel abuts, and the foot of the foot forming an arch It is formed in at least one region of at least one of the arch portion on the inner side or the outer side of the foot on the outer side of the foot, and may be made of a rubber material.

Thus, the edge of the insole 20 is formed to be convex corresponding to the concave formed region of the insole fixing portion 34 described above, again, accordingly, the length or width of the insole 20, the midsole 30 It is at least equal to or smaller than the length or width.

Specifically, when describing the relationship between the insole fixing portion 34 and the insole 20 described above, the insole fixing portion 34 is at least one of the heel shaft portion, the forefoot shaft portion, the arch portion, and the lateral portion of the foot as described above. Above, preferably, there may be at least four regions as shown in FIG. 4. Placing the insole fixing portion 34 in one of these areas, considering that the contact area between the insole 20 and the midsole 30 may be relatively small as described above, the insole 20 and the midsole ( 30) is to minimize the possibility that the insole can be separated, and by providing such an insole fixing portion 34, the insole 20 is not separated from the midsole 30, but rather is intended to reinforce the fixing force.

In addition, in the shape of the insole fixing part 34, one area of one side of the shoe in contact with the insole 20 while in contact with the user's foot is convex or concave. The edges are formed to be convex in response to this so that they are fixed in a shape that meshes with each other, and the upper portion of the insole fixing part 34 is convex to cover a region of the edge of the insole 20, thereby reducing this fixing force. It is to strengthen. Of course, in this case, it would be preferable that the height of the insole 20 is formed to be equal to or smaller than the height of the insole fixing portion 34.

In addition, the insole fixing portion 34 described above is included in at least four regions, in particular, that the insole fixing portion 34 is protruded so that it can come into contact with the user's foot. At this time, the insole fixing portion 34 Since the user may feel uncomfortable with the shape of ), the area in contact with the user's foot is minimized, and the fixing force is maintained by placing it in the upper, lower, left, and right four areas of the midsole 30.

Through this, the fixing force is strengthened by fixing the position of the insole 20, so that even when the user's activity is strong, the insole 20 and the midsole 30 of the shoe are not separated, so there is an effect of extending the usable period of the shoe. .

That is, depending on the structure in which the insole fixing portion 34 further included in the midsole 30 exists, the length of the insole 20 is equal to or smaller than the length of the midsole 30, and the width of the insole 20 is the midsole ( It is formed equal to or smaller than the width of 30).

In particular, the insole fixing part 34 is composed of a rubber material, since the insole fixing part 34 can reach the user's feet, it is not hard due to the nature of the rubber material, so there is a risk of trauma such as being scratched even when it comes into contact with the user's feet. There is no, and since it is a part that is engaged with the insole 20, it is to minimize the wear of the insole 20 even if it is rubbed with the insole 20. Of course, in the present invention, rubber may be used as an example, but in addition, if necessary, the insole fixing part 34 may be formed of various materials.

On the one hand, the midsole 30 of the present invention has an antibacterial function and an elastic function by using various materials. Specifically, the midsole 30 of the present invention may use different materials between the upper and lower portions as shown in FIG. 2.

In order to perform the functions of the midsole 30 described above, the upper portion 31 of the midsole is provided with an antibacterial function by including at least a silver nano material, and the lower portion 32 of the midsole is made of at least one or more of urethane, latex, and silicone. By including it, the elastic function is provided.

In the present invention, in utilizing various materials having an antibacterial function, silver nano is used. Silver nano is an antimicrobial material by coating nano-sized silver particles on polypropylene, and is applied by using silver that is safe for the human body while killing more than 650 kinds of microorganisms that cause diseases. This is to use the antibacterial and sterilizing effect of silver. This silver's effect prevents the growth of bacteria and helps eliminate mold.

However, these benefits cannot be achieved with silver lumps themselves. This is because the surface of the silver in which the reaction will occur cannot be enlarged with an expensive silver lump. So, silver nano, which uses nanotechnology to fully utilize the above-described effect of silver, means one billionth, and one nanometer corresponds to ten thousandths of the thickness of a hair.

Nano-level materials have new properties that are different from existing materials. The same goes for silver. In the nano-state, silver is no longer silver, but rather black. In order to widen the surface of silver, explaining the principle of making silver into fine particles of nanometers is explained. A silver plate is installed where tap water is supplied and electrodes are connected. If power is supplied to the silver plate while water is being supplied, the silver plate is electrolyzed and silver ions (Ag+) escape and mix with water. At this time, several silver ions aggregate to form a colloidal state to maximize the reaction surface.

Of course, in the present invention, silver nano may be used as a material having the above-described antibacterial function, but in addition, polyester fiber, acrylic fiber, cellulose (natural) fiber, polyamide fiber, polypropylene fiber, polyurethane fiber, etc. Alginic acid, PVA, nylon, dithiocarbamate wool, acrylonitrile, polyacrylic, polyolefin, etc. can be used, and materials that have been continuously commercialized in the related art are mainly polyester-based and cellulose-based fibers. The present invention can be used without limitation in the use of a material having an antibacterial function, and it can be used not only by mixing, but also by applying a coating, etc., in addition to using the material, or by adding various other processes to provide an antibacterial function. It would be desirable to understand that it should be added.

Therefore, 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 wearing the shoe, thereby removing foot odor. Or, it is possible to improve hygiene when wearing shoes, and this function is further combined with the midsole 30 of the present invention to maximize breathability, so that there is little smell inside the shoes along with a dry feeling when using the shoes.

In addition, the lower portion 32 of the midsole in the present invention may be provided with an elastic function by including at least one or more materials of urethane, latex, and silicone. As a material having an elastic function, not only the above-described urethane, latex, and silicone Materials such as thermoplastic polyurethane (TPU) foam, polyurethane (PU), and EVA (Ethylene-Vinyl Acetate) can also be used. In addition, rubber materials such as natural rubber, spandex, butyl rubber (PIB), fluoro elastomer, elastomer, ethylene-propylene rubber (EPR), and styrene-butadiene rubber (SBR) may be further used.

Particularly, in the above-mentioned material with elastic function, having elastic function means that it has the ability to resist distortion or distorting influences or forces, and has the function of returning to its original shape and size when the same force is removed. As a result, in addition to the above-described materials, any material that has a sufficient function of elasticity may be used without limitation.

By using the above-described material having the elastic function, while supporting the material having the antibacterial function of the upper portion 31 of the midsole, by providing an elastic function or a cushion function, it is possible to alleviate the impact that a user may feel when walking. It will have an effect.

In addition, in some cases, the midsole 30 may be coated with an abrasion-resistant material with one or more regions in which the load of the foot is relatively heavier than the other region of one region of the midsole 30 when the user wears shoes. will be.

This is a configuration in which the midsole 30 is mainly included in footwear (sneakers, etc.) with strong activity. As the activity is high, the speed at which the shoe wears will also be relatively faster than other footwear, so that wear is prevented by coating it with an abrasion-resistant material. 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 a fiber having performance, or may be coated with a material obtained by liquefying the fiber having self-healing performance. Or, instead of coating, you could add a material that does not wear well. Of course, it is preferable that the above-described coating area is mainly coated on an area where the load by the user's foot is applied relatively stronger than that of the other area.

Therefore, by using the above-described functions, that is, a material having an antibacterial function and a material having an elastic function, while preventing the occurrence of bacteria that may occur inside the shoe, the elastic function, which is the original function of the midsole 30, is further strengthened. While adding cushioning, the shoes are not easily worn through the abrasion-resistant properties of the shoes, and functionally combined with the breathability function through the midsole vent (33), the user's feet are not overwhelmed and the shoes are more comfortable and comfortable to wear. It has the effect of making it comfortable to use.

On the other hand, the midsole 30 with improved ventilation and antibacterial function in the present invention and the shoes including the same have a body 10 in which the outer skin covers the feet except for the openings that allow the user to put their feet on the shoes. ), in a shoe including an insole 20 in contact with the user's foot and in contact with the user's foot, an outsole 40 in contact with the ground, and a midsole 30 between the insole 20 and the outsole 40, 30) is at least one midsole vent 33 formed to allow air to flow in the upper portion and at least one region of the edge of the upper portion 31 of the midsole protrudes in a vertical direction with the ground, but one side that does not contact the outside of the shoe One area of the insole fixing portion 34 is formed concave.

The midsole 30 in the shoe including the midsole 30 may be understood as being composed of the same material as the above-described midsole 30 or performing the same function. That is, even in the shoes including the midsole 30, the air is circulated inside the shoe at the user's weight pressure when the user walks by including a plurality of midsole vents 33 that allow air to flow inside the shoe. By having a function that prevents the user from staying in, it increases the breathability of the shoes by keeping the shoes dry, thereby removing moisture from sweat generated while the user wears the shoes, so that they can wear the shoes in a comfortable state. Has an effect.

In addition, in the shoes including the midsole 30 with improved ventilation and antibacterial function, the insole fixing portion 34 is a heel portion where the user's heel abuts at the edge of the midsole 30, a heel portion where the forefoot abuts, It is preferable that the foot is formed in at least one region of the arch portion of the inner side of the foot forming an arch or the outer side of the foot of the outer side of the foot, and is made of a rubber material.

That is, even in the shoes including the midsole 30 with improved ventilation and antibacterial function, as described above, the midsole 30 has a plurality of midsole vents 33 formed so that the insole 20 and the midsole 30 contact Considering that the area may be relatively small, this is to minimize the possibility that the insole 20 and the midsole 30 may be separated, as shown in FIG. By adding 34), the insole 20 is not separated from the midsole 30, but rather is for reinforcing the fixing force.

Through this, the fixing force is strengthened by fixing the position of the insole 20, so that even when the user's activity is strong, the insole 20 and the midsole 30 of the shoe are not separated, so there is an effect of extending the usable period of the shoe. .

Likewise, the use of rubber as a material, as described above, is not hard due to the nature of the rubber material, since the insole fixing part 34 can reach the user's foot, as described above, so that there is a risk of trauma such as scratching even when it comes into contact with the user's foot. There is no, since it is a part that is also engaged with the insole 20, it can be understood as to minimize the wear of the insole 20 even if rubbed with the insole 20.

Thus, by adding a feeling of thickness to the insole 20 in order to further increase the comfort when wearing to the user, which is one of the functions as a shoe, the height of the insole 20 in the shoe including the midsole 30 of the present invention is at least Equal or greater than the height of the fixing part 34, the upper part of the insole 20 covers an area of one surface of the upper part of the insole fixing part 34, and the lower part of the insole 20 is concave in the fixing part of the insole 20 It is preferable that it is formed to be convex in correspondence with a region formed to be formed.

That is, referring to FIG. 5 together, preferably, the insole fixing portion 34 in the shoe including the midsole 30 is a region in which the edge of the midsole 30 or a part of the outline rim protrudes, and one side The silver shoe may have a concave shape in one area on the opposite side and a convex shape in another area in contact with the outside of the shoe, and one area on the opposite side (as opposed to the one in contact with the outside of the shoe). Preferably, in the same manner as the insole fixing part 34 described above, as shown in FIG. 5, an upper region of the insole fixing part 34 has a convex shape, and a lower region has a concave shape. It can be.

As described above, one surface of the insole fixing part 34 has a convex or concave shape, and most preferably, the edge of the insole 20 is convex corresponding to this for a concave area under the insole fixing part 34. It is formed to form a shape that meshes with each other to be fixed, and the region extending from the lower portion of the insole 20 is concave in response to the convex region of the upper portion of the insole fixing part 34. And, with this, the upper part of the insole 20 covers a region of the outer surface of the upper part of the insole fixing part 34.

That is, according to the above-described configuration, the side surface of the insole fixing part 34 may be in the form of a digut (c) shape according to an example, as shown in FIG. 5.

In this way, as the thickness of the insole 20 increases, the user can feel a sufficient cushioning feeling through the insole and at the same time alleviate the impact that may be felt when walking due to the load of the user's foot, and at the same time , As the insole fixing part 34 is covered by the insole 20, the user's feet do not touch the insole fixing part 34, so that foreign bodies and the like are not felt.

In addition, in the shoes including the midsole 30 with improved ventilation and antibacterial function, the upper portion 31 of the midsole is provided with an antibacterial function by including at least a silver nano material, and the lower portion 32 of the midsole is provided with at least urethane, latex, By including at least one material of silicone, an elastic function is provided.

The antibacterial function through silver nano material and the elastic function through material such as urethane, latex, silicone, etc. may have the same composition or material as the upper portion 31 of the midsole and the lower portion 32 of the midsole described above. Although they may be different from each other, it will be desirable to understand that they perform the same function or purpose in that they have antibacterial functions and can have elastic functions.

Of course, in some cases, even in the shoes including the midsole 30, when the user wears the shoes, one or more regions of the midsole 30 in which the load of the foot is relatively heavier than the other regions are one or more regions of Teflon ( PTFE), or organic molybdenum (AOMC) may be coated with a wear-resistant material.

That is, by using a material having an antibacterial function and a material having an elastic function together with the configurations as described above, while preventing the occurrence of bacteria that may occur inside the shoe, the elastic function, which is the original function of the midsole 30, is further strengthened. Therefore, the shoes are not easily worn through the abrasion resistance properties of the shoes while adding a cushioning feeling, and functionally combined with the breathability function through the midsole vent (33), the user's feet are not overwhelmed and the shoes are comfortable to wear. It has the effect of making it more comfortable to use.

In addition, in order to additionally enhance the ventilation function, the insole 20 in the shoe including the midsole 30 is matched to one or more midsole vents 33 so that air flows through the body 10 and formed at least one insole vent ( 21).

That is, as shown in FIG. 5, preferably, one insole vent 21 is 1:1 to one midsole vent 33 to be matched between vents, through which the midsole 30 and the insole (20) By strengthening the ventilation function of the liver, the fluidity of the air in the shoe body 10 becomes more active, so that moisture due to sweat when the user walks can be minimized.

As a result, the midsole 30 in the shoe including the midsole 30 in order to enhance the ventilation function can be understood to be the same as the function of the midsole 30 described above, and the insole 20, the neighboring sole It will be understood that all components, such as (40), are also included in the shoes or the principle of operation is also applied in the same way.

As described above, although the embodiments have been described by the 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", "comprise" or "have" described above mean that components without a description to the contrary may be included, and thus 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.
