Description

Shoe insole with graphite for supporting health}

The present invention relates to a health functional shoe insole containing graphite, and in particular, the graphite sheet (Graphite), heat absorption is fast and maintains the proper temperature itself, and can block the water wave, anion sheet, activated carbon layer and ocher layer The present invention relates to a functional shoe insole containing graphite that emits negative ions or far infrared rays, which are beneficial to the human body.

Shoe insoles are disposed on the inner bottom of shoes or sneakers or other shoes, and are primarily configured to absorb shocks to the foot when walking or running. The insole of the shoe absorbs the impact and prevents strain on the joints. Therefore, the shoe insole is basically made of a soft material to prevent the fatigue of the foot. For the purpose of shock absorption, most shoe insoles are cushioned materials. It consists of.

Shoe insole is a method of coating latex blends containing foaming agent to a certain thickness in a unit unit and cutting the vulcanized compound into a foot shape, and foaming by combining a certain thickness of EVA (Ethylene-Vinylacetate) sponge sheet with the fabric It is manufactured using a method of cutting with a fabric, a method of laminating and heating the EVA sponge and the fabric, and then inserting, pressing, and cooling molding into a cooling press mold, and foaming the polyurethane stock solution in the mold.

Conventional shoe insoles are predominantly foam insoles, but these foam insoles have a disadvantage of sweating and sticking to the floor after two weeks of wearing.

Recently, many shock absorbing insoles have been developed to replace the foam insoles. Such insoles are generally made of gel plymer, polyurethane, natural rubber, etc., and are formed in a honeycomb structure that is ideal for shock absorption using natural rubber and special gel plymer. The cross-sectional structure of the insole is a three-layer structure in order from the bottom layer to polyurethane, plymer gel, and cloth.

Polyurethane acts as a pedestal, and plymer gel is a shock absorber that also serves as a massage effect on the soles of the feet, and the fabric covered on the top functions to reduce friction and absorb sweat.

In addition, the shoe insole is designed to correspond to the shape of the sole, so that the cushion member is attached to the upper part of the heel or the arch to improve the fit by absorbing the shock applied when the person walks the floor while walking, but the cushion member is used for a long time. In this case, the foot surface is not uniform due to compression due to impact, and foreign substances are mixed, and the foot is easily tired due to the severe foreign body feeling while walking.If the shoes are worn for a long time, odor is generated by sweat and secretion generated by the foot. .

On the other hand, looking at the technology to attach the cushion member to the wheel cup in order to improve the problem of the shoe insole and reduce the odor while protecting the health of the foot, about half the size of the shoe insole in Korea Patent Publication No. 10-2006-0055724 It proposes a functional shoe insole that absorbs the shock applied to the foot by combining a sealed air bag by filling a predetermined amount of air around the cushion pad of the auxiliary insole in which the through hole is formed in the portion corresponding to the heel. Utility Model Publication No. 20-0430914 attaches a shock absorbing member to the lower surface of the upper member to absorb a shock, and forms a lower member having the same shape as the members on the lower portion thereof to absorb the shock to reduce fatigue and ignition feeling Shoe insole has been proposed for height.

However, the above-mentioned shock-absorbing shoe insole absorbs the impact force applied to the heel uniformly without considering the distribution of pressure applied to the surface of the sole, so that the impact force applied to the heel portion causes muscle stiffness during walking for a long time. Increased fatigue, there is a problem that bad odor due to the secretion of sweat due to muscle stiffness.

And to look at the technology to attach the cushion member to the arch portion in order to improve the problem of the shoe insole as described above, in the Republic of Korea Patent Application Publication No. 10-2005-0011001 in between the insole top plate and the insole bottom plate such as EVA And a cushioning unit, which is a pack of gels mixed with cold and hot media, is formed to correspond to the arched part, and proposes a customized shoe insole that facilitates massage effects and fatigue recovery, and the Republic of Korea Registered Utility Model Publication No. 20-0427686 A technology has been proposed to improve the fatigue and ignition of the foot by absorbing the impact applied to the foot by providing a cushion mat recessed in an arc between the upper window in contact with the sole and the lower window curved to a certain height corresponding to the shape of the foot.

However, as described above, when the cushion member is positioned corresponding to the arch of the sole, the impact on the ground is doubled by the load applied to the heel, and the load is distributed in the latter part of the sole of the foot for a long time, resulting in muscle stiffness and blood vessels. There is a problem that quickly feels tired due to pressure.

On the other hand, modern people live while wearing shoes for most of the day, the shoes are formed to surround the entire foot is bound to be blocked from the outside air. As a result, various bacteria such as bacteria are multiplied by sweat and shoes secreted from the soles of the feet, causing a substance called isovaleric acid to produce a bad smell. Fungal fungi multiply between the soles of the feet, heel, and toes. Generates. Accordingly, since the shoe insole is a part directly in contact with the foot, it is desirable to have hygroscopicity, deodorization, and antibacterial property to maintain a comfortable state.

However, the conventional shoe insoles are mainly focused only on the shock absorbing effect, which is the original purpose of the insole, and the situation is not much effect on hygienic parts such as foot odor removal or athlete's foot protection. Although there were some shoe insoles that eliminate foot odors, they also did not achieve their intended purpose by relying on the dilution of the odor by the fragrance rather than eliminating the source of the odor.

In order to achieve this purpose, Korean Utility Model Publication No. 1999-0038017 "Shoes using loess" applies a loess covering plate coated with cotton yarn on the upper surface of compressed leather or artificial leather, and a mixture of ocher and herbal medicine on the upper surface of the support layer. Shoe has been suggested that the effect of fatigue, odor removal, sterilization by lamination, Patent No. 10-0311948 "Shoes insole" is 20% Doc, 10% pulp, 55% ocher between two sheets of EVA plate, Shoe insoles that promote blood circulation and facilitate metabolism have been proposed by making pressurized and fused shoe insoles containing 7.5% jade, 7.5% biotite, and some rosin.

However, in the case of shoes using ocher, there is a problem that the durability of the ocher covering plate may be damaged when the shoes are worn or the shoes are washed for a long time, and the shoe insole is Doc, pulp, ocher, jade, biotite Since such components are wrapped in a thick EVA plate, there is a limit to the function of promoting blood circulation and smoothing metabolism, and the effect of removing odor and sterilization is practically hard to show.

In addition, there have been attempts to improve the health by incorporating powders such as ceramics, loess, and charcoal into the shoe insoles, but the radiation from the far-infrared rays and negative ions naturally generated by the various materials in the insoles is insignificant. There has been a lung disease that does not see a beneficial effect on the human body.

On the other hand, the shoes are inevitably worn throughout the four seasons, shoes having excellent breathability is cold feet in the winter, and in the case of shoes having excellent heat retention sweat in the summer has a problem.

The problem to be solved by the present invention is to provide a health functional shoe insole that can alleviate the impact of the foot when walking and release the negative ions or far-infrared rays beneficial to the human body.

Another problem to be solved by the present invention is to provide a healthy functional shoe insole that can maintain the constant temperature throughout the four seasons by keeping the temperature of the foot itself in the warm temperature in the winter warm and fast by maintaining the proper temperature itself.

Another problem to be solved by the present invention is to prevent the occurrence of mold or pathogens caused by moisture on the bottom surface of the shoe insole or exterior, and to prevent sweat or ticks on the surface in contact with the human skin To provide a hygienic health functional shoe insole.

Another problem to be solved by the present invention is to improve the external release rate of negative ions or far infrared rays generated inside the shoe insole.

According to one aspect of the present invention, the injection molded insole body having a material and thickness to provide a restoring force; And an upper facing material made of an antibacterial or breathable fiber material covering the upper front surface of the insole body; A graphite-compound coated graphite sheet formed between the upper facer and the insole body and covering the upper front surface of the insole body; Anion sheet which radiates anion; Activated carbon layer containing a compound coating activated carbon containing wood vinegar in the sheet; And a graphite-containing health functional shoe insole comprising an ocher compound coated ocher layer on the seat.

The insole body wraps around the heel, rounded concave rounded heel, extending to the heel and arched along the concave portion of the sole, arch support for contacting the sole of the foot, front part for supporting the heel and toe, heel Heel cushion part which is laid after part of bottom part of part is exposed and part is exposed, Forel heels that are partly exposed after part is formed after recess is formed in part of boundary area of arch support part and front part in correspondence with front heel It may include a cushion portion.

A plurality of through holes may be formed in the front portion of the insole body such that the graphite sheet, the anion sheet, the activated carbon layer, and the ocher layer are exposed through the upper exterior member, the graphite sheet, the anion sheet, the activated carbon layer, the ocher layer, and the insole body.

The activated carbon layer and the ocher layer may be formed on one sheet, and the activated carbon containing wood vinegar may be compound coated on the first side of the sheet, and the ocher may be compound coated on the second side of the sheet.

The active layer and the ocher layer may be formed on each sheet, each sheet comprising an activated carbon sheet having an activated carbon layer coated with a compound containing activated carbon containing wood vinegar; And an ocher sheet on which an ocher compound-coated ocher layer is formed.

According to the present invention, by using the graphite sheet, heat absorption is fast and maintains a proper temperature by itself, thereby keeping the temperature of the foot warm in winter and cool in summer, thereby keeping it constant throughout the four seasons. In addition, the anion sheet, the activated carbon layer and the ocher layer may emit an anion or far infrared rays beneficial to the human body. Accordingly, it is possible to provide an effect of improving the constitution, especially for the candidates for examination and fatigued office workers.

In addition, the activated carbon layer containing wood vinegar solution having antibacterial and antiseptic ingredients and the upper surface of the antibacterial or antimicrobial fiber material prevent the occurrence of mold or pathogens due to moisture on the inside of the shoe insole or the bottom of the exterior. As the upper exterior material is a breathable antibacterial fiber material, it is possible to provide a hygienic environment by preventing sweat or ticks on the surface in contact with the human skin.

In addition, the graphite sheet, the anion sheet, the activated carbon layer, and the ocher layer are formed in the form of a thin sheet between the upper exterior material and the insole body, and a plurality of through holes are formed to form negative ions generated inside the shoe insole through the through holes. The external emission rate of far infrared rays can be improved. Accordingly, far-infrared rays, anions and bactericidal components are continuously generated in the shoes, thereby having a maturation effect due to blood circulation and metabolism activation, thereby providing a role as an oxygen catalyst to help the user's efficient activity on oxygen.

In addition, by assisting the blood circulation by the far-infrared radiation by the ocher layer makes the blood flow vigorous and feel warm, and also good nutrition.

In addition, the negative ions are continuously generated by the anion sheet to deodorize and energize the cells in the body and cleanse the blood, thereby improving the resistance and has a useful effect on health. For example, tourmaline, which can be used as an anion sheet, generates anions due to environmental changes, is charged by impact, and also forms adsorption repulsion and electric fields, and has a combination of antibacterial and freshness retention effects to protect the feet. It has the effect of deodorization to remove odors.

In addition, according to the present invention, because of excellent ventilation and antimicrobial activity, the user's clean foot management is possible, and the effect of controlling the user's body temperature, and can remove moisture in the shoe, eczema and athlete's foot It is effective to prevent or alleviate the same foot disease.

1 and 2, the graphite functional health insole 100 according to the present invention includes an upper exterior material 110, the insole body 160. The graphite sheet 120, the anion sheet 130, the activated carbon layer 140, and the ocher layer 150 may be disposed between the upper exterior member 110 and the insole body 160. The upper exterior member 110 and the insole body 160 is firmly bonded by compression.

Upper housing 110 is preferably made of cotton fabrics excellent sweat absorption and breathability. The upper exterior member 110 may be made of a breathable antimicrobial fiber material or antibacterial fiber material. The upper sheath 110 may be, for example, 100% polyester fiber self-treated, may be microfiber or silver nano fiber self-treated, or may be Mary mesh fiber. Accordingly, sweat or ticks may not be inhabited on the surface of the upper exterior member 110 in contact with the human skin, thereby providing a hygienic living environment.

Insole body 160 may have a thickness that provides antimicrobial and resilience. As the material of the insole body 160, it can be used as a material such as EVA (Ethylene Vinyl Acetate), polyurethane (PU), latex, and the like having excellent elastic resilience. In case of using EVA, it is possible to use EVA of multi-layer structure by attaching various kinds of sheet state of EVA and making it into sheet form and then cutting it to thickness.

EVA (Ethylene-Vinyl Acetate copolymer) is used as a raw material resin for footwear, agricultural film, extrusion coating because of its excellent transparency, flexibility, and low temperature brittleness, and it has excellent ductility to replace PVC (polyvinyl chloride polyvinyl chloride). It is attracting attention as a material. Its characteristics are excellent in elasticity, transparency, elongation rate and tensile strength compared to LDPE which is a general homopolymer.

 Insole body 160 may be, for example, 100% polyester material antibacterial. In addition, the material of the insole body 160 uses all kinds of plastic materials currently available. For example, nylon, polypropylene (PP), glass fiber, and composite plastic mixtures can be used. The composite plastic mixture may be used by mixing polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) or by mixing nylon and glass fiber, for example.

In addition, as a material of the insole body 160 to absorb shock during walking or to soften the texture of the shoe insole, neoprene rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (BR), chloroprene rubber ( Thermoplastic rubber (TPR) such as CR may be used. The material of the insole body 160 may be used any material that can be employed by those skilled in the art as a material capable of performing a shock-absorbing function by excellent elastic restoring force, it is not limited to the material illustrated here.

Insole body 160 may be manufactured by plastic mold technology. General plastic molding methods vary widely, but are roughly classified into injection molding, compression molding, trans molding, thermoforming, blow molding, film blowing, extrusion molding, calendering, and fiber spinning. Among them, injection molding, compression molding, transfer molding, and rotational molding are a method of pushing and molding a plastic material into a closed mold, that is, a cavity formed between two molds closed to form a molded article.

The insole body 160 is determined according to the mold shape of the mold frame, which is not in contact with the ground by the bone portion corresponding to the boundary portion between the toe of the shoe wearer's foot and the sole of the shoe, and the streamlined structure of the sole. It may be made of a shape that can support the ball portion that is not part.

The graphite sheet 120 is a sheet coated with graphite compound. The anion sheet 130 is a sheet in which an anion emission material is formed to emit anion. For example, tourmaline may be used as the anion sheet 130. The tourmaline presented at the Adan Mine Central Research Institute, Japan, stated that "the anode and cathode spontaneously occur at both ends of the crystal of the tourmaline ore, and as a result, the nervous system is connected to the cells of plants and animals located in the field. A current of 11 microns and 0.06 milliamps of current having the same wavelength as that of controlling current flows in. Anion is generated and charged by shock due to environmental changes such as temperature, humidity, friction, etc. Adsorption, repulsion and electric field Antimicrobial and freshness-retaining effects are obtained by the combined action of the formation of electrons, etc. Particularly, negative ions give vitality to the cells, purify the blood, and enhance resistance. , The analgesic effect to suppress the excitability of the sympathetic nerve), and the autonomic nerve adjustment function.Far infrared rays warm the cells in the deep body of the human body, improve blood circulation, It activates the cells by activating death. " It is known.

The activated carbon layer 140 is formed by compound coating treatment of activated carbon containing wood vinegar in a sheet. The activated carbon layer 140 containing wood vinegar emits a large amount of far infrared rays. Far infrared rays are a kind of electromagnetic waves that strongly reflect the power to warm a substance to expand capillaries of the human body to facilitate blood circulation and It helps to circulate. In addition, the activated carbon layer 140 containing wood vinegar is excellent in purifying action because it increases the negative ions by adsorbing cations, and activated carbon baked at a high temperature has an excellent humidity control effect because it contains little moisture. That is, when the humidity is high, the moisture is adsorbed to reduce the surrounding humidity, and when too dry, the moisture is released to naturally control the humidity. Accordingly, the activated carbon layer 140 containing wood vinegar can remove moisture in the shoe, thereby improving an environment in which fungi such as eczema or athlete's foot are easily inhabited, thereby preventing or alleviating foot disease. .

The ocher layer 150 is formed by coating the ocher compound on the sheet.

In FIG. 2, the graphite sheet 120, the anion sheet 130, the activated carbon layer 140, and the ocher layer 150 are arranged between the upper exterior member 110 and the insole body 160. The order of the arrangement of each sheet was selected through the optimal arrangement in various tests for experimental negative ion radiation, far infrared radiation, and water wave blocking. However, the present invention is not limited thereto, and the order in which the layers are arranged may be modified as necessary.

In addition, each material layer is implemented in each sheet in FIG. 2. This was chosen in consideration of the manufacturing process of each sheet. However, the present invention is not limited thereto, and two or more layers of materials may be implemented in one sheet as needed. For example, although the activated carbon layer 140 and the ocher layer 150 containing wood vinegar are embodied in separate sheets in FIG. 2, the active carbon is formed by compound coating activated carbon containing wood vinegar on the upper surface of the sheet, for example. A layer may be formed (not shown) and the ocher layer (not shown) may be formed by compound coating ocher on the lower surface of the sheet.

When implementing two layers of material in one sheet, it is preferable to select a sheet having a relatively thick thickness when implemented in each sheet in consideration of the thickness of each material permeating the sheet. In this case, for example, a non-woven fabric may be used. The nonwoven fabric may perform a function that can alleviate the impact of the foot along with the insole body 160 as it has a cushioning property of the material. You can keep your foot soft. For example, the thickness of the insole body 160 may be appropriately adjusted using the properties of such nonwoven sheet.

The front portion of the insole body 160 penetrates the upper exterior member 110, the graphite sheet 120, the anion sheet 130, the activated carbon layer 140, the ocher layer 150, the insole body 160, a plurality of through holes 170 is formed. Part of the graphite sheet 120, the anion sheet 130, the activated carbon layer 140, and the ocher layer 150 is exposed through the plurality of through holes 170. That is, the through hole 170 improves the external emission rate of far infrared rays or negative ions emitted from the graphite sheet 120, the anion sheet 130, the activated carbon layer 140, and the ocher layer 150 embedded in the shoe insole 100. And to improve the antimicrobial or bactericidal activity. In addition, the plurality of through holes 170 improves ventilation. The plurality of through holes 170 formed in the front portion of the insole body 160 is formed from the graphite sheet 120, the anion sheet 130, the activated carbon layer 140, and the ocher layer 150 exposed by the through holes 170. The graphite sheet 120, the anion sheet 130, and the activated carbon layer 140 improve the direct release rate of far infrared rays or negative ions released into the air, while occupying the through hole 170 in the area of the entire shoe insole 100. , To reduce the area of the ocher layer 150. Therefore, the number of the through holes 170 should be appropriately adjusted in consideration of the external discharge amount directly discharged into the air by the through hole 170 and the external emission amount released through the upper exterior member 110 or the insole body 160. something to do. For this reason, the present invention was formed by defining the through hole 160 in the front portion of the insole body 160. However, the present invention is not limited thereto, and the position or number of the through holes 170 may be discharged through the external discharge amount directly discharged into the air by the through holes 170 and the upper exterior member 110 or the insole body 160. It may be appropriately set in consideration of the external emission amount.

Figure 3 is a view for explaining the molecular structure of the graphite used in the functional footwear insole according to the present invention, Figure 4 is an enlarged photograph of graphite, Figure 5 is a photograph showing the layer structure of graphite.

3 to 5, the graphite used to fabricate the graphite sheet 120 is stable with the best heat dissipation electronic materials such as semiconductors and LEDs with excellent heat conduction characteristics. Graphite is the best material for nanocomposites because of its excellent chemical stability.

Graphite means graphite used for pencil lead. Graphite is a material forming a honeycomb two-dimensional planar structure in which carbon is connected to each other in a hexagonal shape as shown in FIG. 3. Graphite has unique physical and chemical stability and has semiconducting properties that cannot be obtained from other materials such as lubricity, heat resistance, corrosion resistance, electrical conductivity, thermal conductivity, and workability, so that high thermal conductivity heat dissipation material and electrical conductivity (horizontal, vertical thermal conductivity) ) Is an excellent material. For example, graphite shows a thermal conductivity effect that is three times better than copper or aluminum. In addition, graphite is optimal as a seal material with excellent flexibility and compression recovery.

Therefore, the graphite sheet 120 using graphite can quickly absorb heat and block water pulses while maintaining a proper temperature by itself. In addition, the graphite sheet 120 does not generate harmful electromagnetic waves.

The graphite sheet 120 is pulverized graphite by an artificial processing process using a pulverizer, etc. to form a powder in the form of fine particles, and the powder formed as described above is put into a mixing container of a constant capacity and mixed with a water-soluble adhesive. By stirring the form to form a liquid graphite coating material.

In this case, the mixing volume ratio of the graphite powder and the water-soluble adhesive introduced into the mixing container may be mixed in the range of 60% to 10% of the water-soluble adhesive with respect to the powder, such as 40% to 90%. The liquid graphite coating material thus prepared is applied by spraying or applying a sheet, such as a nonwoven fabric, to give a compound coating. It is then dried, for example in a tunnel dryer, for example at 120 ° C. to 180 ° C. for 5 to 10 minutes heat treatment.

Thus, the graphite-coated graphite sheet 120 may be thinly cut to fit the size of the shoe insole in the unfolded state as shown in FIG. 6, and may be stored in a roll as shown in FIG. 7.

Likewise, the activated carbon layer 140 is formed by compound coating the activated carbon containing wood vinegar on the sheet by applying a process of manufacturing a graphite sheet. In order to form the activated carbon layer 140, the activated carbon is pulverized by an artificial processing process using a grinder or the like to form wood vinegar when the powder is formed in the form of fine particles. Activated carbon has fine pores even when it is a powder in the form of fine particles, and activated carbon contains wood vinegar using the fine pores.

Wood vinegar is a material that naturally cools and condenses smoke from the internal temperature of 350 ℃ to 435 ℃ during carbonization (conventional charcoal kiln, mechanical carbonization) of burning charcoal with oak (aka acorn). It is composed of 200 organic substances such as potassium, magnesium, sodium, vitamin B1 and B2. The wood vinegar extracted in this process is a liquid far-infrared emitter material, which penetrates and absorbs quickly, and sterilizes and detoxifies strongly, and is a new natural substance that can be used in various fields such as food, medicine, agriculture, and livestock.

Likewise, the ocher layer 150 is formed by compounding the ocher on the sheet by applying a process of manufacturing a graphite sheet. The activated carbon layer 140 and the ocher layer 150 emit far infrared rays, and provide antibacterial and purifying functions. However, the drying conditions through heat treatment for forming the activated carbon layer 140 and the ocher layer 150 are preferably about 5 minutes at about 150 ℃. This is because the activated carbon layer 140 and the ocher layer 150 are more sensitive to heat than the graphite sheet 140.

The feet of the human body support human weight. In the human body, the skeleton, such as the spine, neck, pelvis, shoulder, etc., maintains equilibrium (horizontal) based on both feet. This foot consists of several bones, so that the weight of the human body is distributed evenly on the foot. In particular, when walking or running, the human body not only supports weight but also serves to absorb shocks from the ground.

However, if the body shape is deformed due to various causes and the structure of the foot is deformed accordingly, the weight of the human body cannot be properly divided and supported on both feet, and the weight is not evenly distributed on one foot. Deformation will come in various parts of the body, causing pain.

8 is a view for explaining the structure of the foot, Figure 9 is a view for explaining that the shock is transmitted to the foot when walking.

Referring to FIG. 8, the foot consists of 26 bones and joints connecting them, and over 100 ligaments for joining these bones and joints. In particular, when looking at the structure of the foot to evenly support the weight of the human body, the human foot in the inner longitudinal arch (inner longitudinal arch), the outer longitudinal arch (outer longitudinal arch), ulnar arch (also known as the upper and lower arches, metatarsal arch) and crossbow (bottom) Also called transverse arches, all four arches of the transverse arch are formed. Referring to FIG. 1 schematically showing the bones of the foot, the arch connecting the points a and b is the inner arch, and the arch connecting the points b and c is the outer arch, and the arch connecting the points a and c It is an ulnar arch and the arch connecting the points d and e is a crossbow. All four of these arches must maintain their normal shape to achieve the original role of the foot, so that the human body is properly balanced and effectively absorbs the impact from the ground in walking or running. In other words, these four arches must maintain their normal shape, so that the weight of the human body is distributed evenly at each of the points a, b, c, d, and e of the foot. As a result, the human body is balanced and the shock is transmitted to the human body. Will be.

However, if the shape is deformed such that the arches are too large or too small out of the normal shape, the weight of the human body is not normally distributed on the sole of the foot, and thus the overall balance of the human body is broken.

Referring to FIG. 9, the walking is generally performed by a landing step (a) where the heel touches the ground, a support step (b) supported by the arch of the sole, and a forward step (c) pushing the ground by the front heel. Is done. As such, when the foot is moved forward, the sole contacts the ground in the order of the heel to the heel, and when the foot comes down from the stairs or when the foot is moved backward, the sole touches the ground in the order of the heel to the heel. Here, the heel portion and the heel portion that are first or last in contact with the ground in the sole structure, the load is more concentrated than the arch portion. In particular, the load is concentrated when the heel contacts the ground, and the load is concentrated when the center of the heel portion is in contact with the ground. Therefore, it is necessary to mitigate the impact on the center of the heel and heel.

Figure 10 shows the front of the healthy functional shoe insole containing graphite according to the present invention, Figure 11 shows the bottom of the healthy functional shoe insole containing graphite according to the present invention, Figure 12 is a graphite according to the present invention Shows the bottom of the cushion member is removed from the health functional shoe insole containing, Figure 13 is a view showing a cross-section AA in FIG. 14 is a view for explaining the heel support in the functional shoe insole containing graphite according to the present invention.

10 to 14, the insole body 160 extends to the concave rounded heel portion 162c and the heel portion 162c so as to surround and support the heel 1 and arcuate along the concave portion of the sole. It is formed of an arch support portion 162b for contacting and supporting the sole, and consists of a front portion 161 for supporting the heel and toes. The concave rounded heel portion 162c reduces lateral shaking of the heel 1 and maintains balance when walking. The arch support 162b supports the sole to reduce foot fatigue and improve balance when walking. After the recess 162d is formed in a part of the bottom surface of the heel portion 162c, the heel cushion portion 164 is laid by adhesion. At this time, the heel cushion portion 164 is partially included in the recess 162d and partially exposed. In addition, after the recesses 162a and 161a are formed in a portion of the lower surface of the boundary area between the arch support part 162b and the front part 161 to correspond to the front heel, the front heel cushion part 163 is laid by adhesion. In this case, the heel cushion portion 163 is partially included in the recesses 162a and 161a and partially exposed. Adhesive laying by the recesses 162a, 161a, and 162d of the heel cushion portion 163 and the heel cushion portion 164, respectively, is the front heel cushion portion 163 and the heel cushion portion 164 when an impact is applied to the heel or the heel. ) Can be prevented from being separated, and because the front heel cushion portion 163 and the heel cushion portion 164 are laid, the thickness can be prevented from becoming thicker than necessary. As the heel cushion portion 163 is installed corresponding to the front heel, the front heel cushion 163 may relieve the impact applied to the front heel by providing a resilient elastic force in the advance step (c) described with reference to FIG. 9. In addition, the heel cushion portion 163 and the heel cushion portion 164 is not formed in the entire heel portion 162c or the front portion 161, but is installed in a partial region is formed in a partial region rather than formed in the whole This improves the cushioning action, and the bottom surface of the insole body 160 is slightly spaced from the bottom of the shoe so that the circulation of air in the shoe is prevented by the cushioning action of the heel cushion portion 163 and the heel cushion portion 164. You can wake up to keep your feet more comfortable.

In addition, the insole body 160 may be largely divided into a front portion 161, a rear portion 162 including an arch support portion 162b and a heel portion 162c. Thus, referring to FIGS. 12 and 13, it can be seen that a boundary is formed between the front part 161 and the rear part 162. Starting from this boundary, the front portion 161 can be bent. This boundary is not a straight line, but is formed in a curved line, which is elastically curved in a right and left balance in comparison with a curved line, and further effectively prevents the front part 161 and the rear part 162 from being separated, thereby making the shoe insole durable. Can improve. Accordingly, by reducing the friction or impact that may act on the front heel as the front portion 161 is bent in accordance with the movement of the toes to prevent abnormally deformed foot structure and can effectively reduce the fatigue of the foot.

The present invention is not limited to the above-described embodiments, and various changes and modifications may be made by those skilled in the art, which is included in the spirit and scope of the present invention as defined in the appended claims.
