Description

Functional insole and manufacturing method of functional insole

The present invention relates to a functional insole and a method for manufacturing a functional insole, by providing a reaction force to the force of the foot of the wearer's body to move in the front upper direction to enhance the upper upper movement force so that the airgel is embedded in the functional insole and functional insole In addition, the present invention relates to a functional insole and a functional insole manufacturing method which can prevent the external leakage of the airgel while making the manufacturing simple and easy.

Many modern people want to exercise regularly even in their busy lives. Nowadays, people often walk or run in comfortable sneakers with light sports clothes. At this time, the shoes placed at the bottom of the body to support the body and directly contact the ground play an important medium for moving the body.

The main functions of shoes can be divided into comfort and functionality suitable for sports activities.

General sneakers such as running shoes use a viscoelastic material as a midsole. In running, the force is transmitted to the body when the heel of the shoe touches the floor.

In walking, 1.2 times the power is transmitted to the body, and in running, the faster the speed, the more than 3-4 times the force is transmitted. At this time, when the heel touches the floor, deformation occurs at the bottom of the shoe. Deformation occurs when an external load is applied to the midsole and returns to its original form when the load is removed. The midsole causes energy loss along with the function of shock absorption during the load transfer.

If so, running shoes with too soft cushions will have a relatively high loss of energy. As the body moves, the energy transmitted to the shoe must be returned to the body as the body moves forward from the viscoelastic material in the midsole. This is called energy return. In the case of running with a constant load on the body, if the cushion is too good, you will feel tired easily due to high energy loss if you continue the exercise.

On the other hand, it can be seen that the midsole is harder in the case of marathon shoes than actually walking shoes. So far, it is known that the general impact force that occurs when the foot touches the ground is not closely related to joint injuries. Rather, studies have reported that a certain amount of continuous impact is effective in maintaining healthy bones.

In each sport, the role of shoes is important to make the best use of the body's functions. For example, a grass soccer field has cleats attached to the bottom of the shoe to prevent slipping and to handle the ball quickly and accurately. The number and height of cleats also vary depending on the weather conditions and the type of turf.

In addition, since the movement varies depending on the position of the football player, the shape of the cleat suitable for this is considered. In the case of major soccer shoes production, brand A and N, we develop soccer shoes for the best performance through the friction test using robots and the kinematic test for real soccer players.

High jumps are required to kick forward in athletics such as 100M sprinting or to intercept the ball in rebounds in basketball. Shoes should satisfy the characteristics of these events. However, the foot is a multi-segmental system consisting of several small bones that make it difficult to understand movement compared to other lower limb joints. It is known that energy is lost as the forefoot flexes around the metatarsophalangeal joint (MTP joint) of the foot. In order to minimize this energy loss, carbon fiber (carbon fiber) material was inserted under the insole in the form of a plate around sports brands of A company and applied to sprinting shoes and basketball shoes.

It can be seen that the loss of power is dramatically reduced in the case of hard carbon fiber midsoles that do not bend well compared to the use of ordinary midsoles when jumping in place. At 100m sprinting, a 2% improvement and a 2.5% (about 2cm) improvement in situ jump height were shown. If you understand the characteristics of the human body and develop a shoe like this, it will be able to perform its best function.

Recently, running shoes have been introduced to reduce excessive ankle pronation to control movement or to reduce the load on the knee joint. Despite these efforts, it is difficult to scientifically identify the effect of shoes. The reason for this is that shoe developers must understand the complex relationships with movement while taking into account the complex anatomical features of the human body. If you make good use of the dynamics of the human body, you will be able to create comfortable shoes that are comfortable and fit the functions required by sports.

In addition, there are no functional insoles for improving the recording of running, running in-place, and the like.

Particularly, in recent years, an insulator made of an airgel is additionally provided to the insole so as to improve the buffering and insulating properties of the insole. In this regard, it is as disclosed in Korean Patent Application Publication No. 10-2015-0112336.

However, since the airgel is usually provided in the form of powder of granules, it was not possible to manufacture the insole in such a manner that the airgel itself was additionally provided to the insole.

That is, as disclosed in Korean Patent No. 10-1237013, the aerogel powder is wrapped in a lamination film in a desired shape, and then formed into an airgel lamination so that the airgel powder does not leak to the outside, which is then glued to the bottom of the insole. There was no choice but to provide a way to attach, this has caused a problem that the entire manufacturing process is complicated and takes a long time.

Moreover, even if the airgel lamination is adhesively attached to the bottom of the insole as described above, the airgel lamination is out of position during the use of the shoe, and thus it is inconvenient to wear without providing stable cushioning and insulation. There was a problem.

Walking, running, etc. The biggest impact on athletic performance during long jumps is the heel lift with heel and the toe lift with toe.

Heel Off Phase is the point at which the heel touches the ground. The foot must act as a lever to move the body forward, with the foot turning outwards, that is, by supination. This abduction allows the joints and bones to be firmly fixed, making the feet firm and ready for propulsion.

Propulsion (Toe Off Phase) is the last stage of the stance where the base is touching the ground, resulting in a foot clearance for smooth progression to the dilator. The knee joint flexes and the ankle joint Let's go. Toe lifting means that the toes push the ground and move forward.

A of FIG. 1 indicates a portion where a toe touches, B indicates a portion where the foot ball touches, and a portion indicated by hatching shows a portion where the foot ball support part 100 is formed.

As shown in Figures 1 to 5, the functional insole according to an embodiment of the present invention is a functional insole 1000 used in the interior of the shoe, between the heel of the functional insole body (foot joint) and the heel Including the foot ball support portion 100 protruding on the corresponding surface, when the igniter bends the metatarsal joint, the support portion 100 by supporting the ground of a predetermined portion away from the ground between the foot ball and the midfoot, the functional insole It is characterized in that the body of the wearer located on the upper surface of the main body improves the forward upper moving force by providing a reaction force to the force to move toward the front upper direction.

When the human body exerts force on the ground, a reaction force is generated against the force, which is called the ground reaction force or the reaction force of the ground.

That is, the magnitude of the reaction force that the ground pushes the athlete is determined by the magnitude of the force that the body pushes the ground.

For example, suppose that you have the same athletic ability, and you look at the power of the soles and insoles when you jump in place.

In general, when using a flat insole,

The front of the toes and footballs spur the ground and transmit the force to the ground. In addition, the front of the toes and the foot ball is affected by the friction with the ground.

However, when using a functional insole according to an embodiment of the present invention,

As well as the front of the toes and the foot ball, the foot ball support portion 100 supports the ground side, and the power to push the ground up to the rear portion of the foot ball can be transmitted to the ground side.

Furthermore, while the back of the ball supports the foot ball support 100 in an inclined state, the rear part of the ball delivers intact force in the direction of movement (front upper) (the direction of the force of the back of the ball to the foot ball support 100) And the back of the foot ball and the foot ball support portion 100 is in contact with the vertical) can be.

In addition, not only the toe and the front of the ball but also the back of the ball are affected by friction with the ground (because the area of the sole that transmits force to the ground is larger than a normal insole).

In other words, when using a functional insole according to an embodiment of the present invention as compared to using a flat insole in general, it helps to improve the recording of the long jump in place. In addition, the elastic force of the ball support portion 100 also helps to improve the recording of the long jump in place.

In this way, in order to improve the front upper movement force, the ball support portion 100 is formed to protrude to the functional insole body (see Fig. 2).

That is, when the heel is lifted, the foot ball is supported on the rear side of the foot ball, thereby providing a reaction force (see the up arrow direction in FIG. 3) to the force (see the down arrow direction in FIG. 3) that the body of the wearer wants to move forward and upward. can do.

A functional insole according to an embodiment of the present invention can help with the improvement of recording such as short-distance running (sprint), in-situ far jump.

As shown in Figure 2, the foot support portion 100 of the functional insole according to an embodiment of the present invention is gradually lowered to the height of the protruding height gradually toward the rear of the functional insole body, but toward the rear It may be characterized by the wedge shape.

Although the figures are shown in the figure does not bias the foot ball support portion 100 to one side, the foot ball support portion 100 is formed to be biased toward the rear of the functional insole main body to be suitable for a lot of movement forward Is suitable for large movements (running, long jump, etc.).

As shown in Figure 2, the foot support portion 100 of the functional insole according to an embodiment of the present invention may be characterized in that it is formed projecting downward.

In order to increase the fit of the wearer, the foot support 100 may be formed to protrude to the lower side of the functional insole body. This can increase the fit by making the part directly touching the sole as flat as possible.

As shown in Figure 4, the foot support portion 100 of the functional insole according to an embodiment of the present invention may be characterized in that it is formed projecting upward.

In order to be in close contact with the shoe, the foot support 100 may be formed to protrude above the functional insole body. This is to make the part directly touching the shoe as flat as possible so that the shoe insole is in close contact with the shoe and there is no floating part.

As shown in Figure 5, the foot support portion 100 of the functional insole according to an embodiment of the present invention may be characterized in that it is formed to protrude upward and downward.

To provide a reaction force to the force that the body of the wearer to move in the front upper direction to further enhance the front upper movement force, the foot support 100 may be formed to protrude above and below the functional insole body. This is to maximize the total height of the protruding height to maximize the reaction force against the force of the wearer's body to move upward and upward.

As shown in Figure 6, the foot support portion 100 of the functional insole in accordance with an embodiment of the present invention may be characterized in that some or all of the porous.

This is because part or all of the foot support 100 is formed to be porous, so that the foot support 100 is more deformed than the functional insole body when the heel is lifted, thereby increasing the wearing comfort of the foot and the foot support 100 The insole body on the side is to bend naturally.

At this time, relatively weakening the contact portion with the foot can further increase the fit.

As illustrated in FIG. 7, the ball support part 100 of the functional insole according to the exemplary embodiment of the present invention may be characterized in that grooves are formed in a slit or a predetermined shape on a part or the whole thereof.

In this case, a part or the whole of the ball support part 100 is formed with a plurality of slits (cylindrical grooves, polygonal grooves, narrow gaps, etc.), so that when the heel is lifted, the ball support part 100 side is more deformed than the functional insole body. To increase the wearing comfort of the shoes, the insole body on the foot support portion 100 side is to bend naturally.

The foot support portion 100 of the functional insole according to an embodiment of the present invention may be characterized in that the elastic modulus is smaller than the functional insole body.

This is to allow the functional insole body to bend naturally.

That is, if the elastic modulus of the foot support portion 100 is high, the deformation of the foot support portion 100 occurs less when the heel is lifted, and thus space may be generated in the foot and the functional insole body. This may be a factor that may reduce wearer's wear, such as a heterogeneous feeling that the wearer is peeled off. In order to prevent this, it is preferable to make the elastic modulus of the ball support portion 100 smaller than the functional insole body.

Although the ball support portion 100 has an elastic modulus smaller than that of the porous, slit-forming or functional insole body, the toe support 200 to be described later is also carried out to have a smaller elastic modulus than the porous, slit-forming or functional insole body. Of course it is also possible.

The foot support portion 100 of the functional insole according to an embodiment of the present invention may be characterized in that the most protruding height is 2 ~ 10mm.

Test Example 1 In-situ Multi-Run Recording Test According to Protruding Height

The most protruding height of the ball support portion 100 is increased to 0 ~ 12mm in 2mm units, to lay a functional insole according to an embodiment of the present invention on the sole of the shoe, in-situ multi-run by 20 students of physical education university As a result of measuring and averaging, the most protruding height of the ball support 100 is 257.3mm for 0mm, 259.2mm for 2mm, 263.4mm for 4mm, 266.5mm for 6mm and 268.6mm for 8mm , 269.9 mm for 10 mm and 270.1 mm for 12 mm were measured.

When the height of the most protruding height of the foot ball support part 100 is increased by 2 mm, an average of 1.9 cm is improved, and when it is increased by 4 mm, an average of 6.1 cm is improved, and when it is 6 mm, an average of 9.2 cm is increased. The recording was improved, and an average of 11.3 cm was improved when the height was 8 mm, an average 12.6 cm was improved when the height was 10 mm, and an average 12.8 cm was improved when the height was 12 mm.

That is, as the height of the most protruding height of the foot ball support part 100 is increased, the recording is improved, but the rising width is gradually decreasing as the height of the most protruding height of the foot ball support part 100 exceeds 4 mm. have.

This means that the recording is not further improved because the height of the most protruding height of the foot support 100 is increased indefinitely, and when the height of the most protruding height of the foot protruding support 100 is increased by 4 mm, the recording increase rate is highest. Appeared.

At this time, when the height of the most protruding height of the foot ball support portion 100 is increased by 12 mm, the situation often occurs when the shoes are peeled off while jumping in place, tightly tightening the sneakers and measuring the records. As such, raising the most protruding height of the ball support portion 100 by 12 mm or more may interfere with recording measurement.

Test Example 2 Sensory Evaluation According to Protruding Height

The most protruding height of the foot ball support unit 100 is increased by 2 mm units from 0 to 12 mm, the functional insole according to an embodiment of the present invention on the bottom of the shoe, and the foot ball for 100 students of physical education university If the height of the most protruding part of the support part 100 is not more than 0 mm, the sensory test is performed to check '1', and if it is very uncomfortable, 5 is checked. 1 is shown.

	1One	22	33	44	55
0mm0 mm	100100	00	00	00	00

10mm10 mm	77	1212	1919	3333	2929
12mm12 mm	00	1One	33	77	8989

That is, although the wearer did not feel much discomfort until the most protruding height of the foot ball support part 100 was 4 mm, the wearer who complained of discomfort suddenly made the most protruding height of the foot ball support part 100 as 12 mm. You can see that the increase.

Based on Test Example 1 and Test Example 2, it is assumed that it is not desirable to increase the height of the most protruding height of the ball support part 100 by 12 mm or more.

As shown in Figure 8 to 11, the functional insole according to an embodiment of the present invention includes a toe support portion 200 protruding on the surface corresponding between the toe and the foot (foot metatarsal joint) of the functional insole body The toe support 200 supports the ground of a predetermined portion away from the ground between the toe and the foot ball (football rear side), so that the body of the wearer located on the upper surface of the functional insole body moves toward the front upper direction. It can be characterized by providing a reaction force to improve the front upper movement force.

It is also necessary to minimize the energy lost after the heel lifter and just before the toe lifter. To this end, the toe support 200 may be formed on the functional insole body (see FIG. 2).

That is, just before the toe lifter, by supporting the toe at the rear side of the toe, the body of the wearer can provide a reaction force to the force to move in the front upper direction.

As shown in Figure 9, the toe support portion 200 of the functional insole according to an embodiment of the present invention may be characterized in that it is formed projecting downward.

In order to increase a wearer's fit, the toe support 200 may be formed to protrude downward from the functional insole body. This can increase the fit by making the part directly touching the sole as flat as possible.

As shown in Figure 10, the toe support portion 200 of the functional insole according to an embodiment of the present invention may be characterized in that it is formed projecting upward.

In order to be in close contact with the shoe, the toe support 200 may protrude upward from the functional insole body. This is to make the part directly touching the shoe as flat as possible so that the shoe insole is in close contact with the shoe and there is no floating part.

As shown in Figure 11, the toe support portion 200 of the functional insole according to an embodiment of the present invention may be characterized in that it is formed to protrude upward and downward.

The toe support 200 may protrude upward and downward from the functional insole body in order to provide a reaction force to the force of the wearer's body to move in the front upper direction to further improve the front upper movement force. This is to maximize the total height of the protruding height to maximize the reaction force against the force of the wearer's body to move upward and upward.

As shown in Figure 12, the functional insole according to an embodiment of the present invention may be characterized in that a predetermined pattern of intaglio, embossed or intaglio and embossed shapes are formed on the bottom.

Even if you place a perfect insole inside the shoe, you can create friction between the shoe and the insole during exercise. To prevent this, shoes and insoles are often glued together.

However, since the functional insole according to an embodiment of the present invention can be worn inside the shoe only for the recording measurement, it is estimated that many people use the adhesive without the adhesive.

Therefore, it is preferable to prevent the shoe and the insole from slipping, and for this purpose, it is preferable to form a groove of a predetermined pattern on the bottom surface of the functional insole according to the embodiment of the present invention. In addition, this reduces the weight of the functional insole and also reduces manufacturing costs.

At this time, as shown in Figure 12, by distinguishing the region of the upper side in the direction in which the toes are located and the lower side in the direction in which the heel is located, it can be characterized in that the upper side is denser than the lower side. This densely forms the bottom of the foot ball side, which is relatively pressured to press the ground, to increase friction, and to form a roughly bottom of the foot side of the foot which is relatively less pressurized to press the ground. This reduces the weight of the insole and also reduces manufacturing costs.

As shown in Figure 13, the functional insole manufacturing method according to an embodiment of the present invention, in the manufacturing method of the functional insole 1000 used to spread in the shoe, the member preparation step (S10), the member lamination step (S20) , Oven heating step (S30), cold press forming step (S40) and cutting step (S50).

As shown in Figure 14 to 16, the functional insole manufactured by the functional insole manufacturing method according to an embodiment of the present invention is not provided to the insole for shoes provided that the insulating material made of aerogel as a separate lamination product In the forming process for the production of functional insoles are provided in the form of a pad with the other members and then press-molded through a batch oven heating and cooling press provided.

Functional insole manufactured through a functional insole manufacturing method according to an embodiment of the present invention as described above is an insulating pad 400 made of aerogel and the upper pad to wrap the insulating pad 400 in the upper and lower and blocking the outside ( 920 and the lower pad 300.

At this time, the upper surface of the upper pad 920 is made so that the distal end portion 910 is provided as a portion directly in contact with the foot.

The member preparation step S10 may include a fabric part 910 made of fabric, an upper pad 920 made of foam having a cushion, a lower pad 930, an insulating pad 940 made of airgel powder, Each hot melt 950 is prepared while being melted by heat.

At this time, the distal end portion 100 is made of fabric and is fixed to the upper surface of the upper pad 920 and the thermal insulation pad 940 is attached and fixed between the upper pad 920 and the lower pad 930. This is as shown in FIG. 14.

In addition, the upper pad 920 is provided as a pad made of a foam having a cushion, in particular, the insulating pad 940 is formed by impregnating the non-woven fabric with the airgel powder.

When the preparation for each

member

910, 920, 930, 940, 950 by the member preparation step S10 is completed, the member stacking step of stacking the

prepared members

910, 920, 930, 940, 950. (S20) is performed.

In the member stacking step S20, the distal end portion 910, the upper pad 920, the insulating pad 940, and the lower pad 930 are sequentially stacked, respectively, and hot melts 950 are interposed between the members. Further lamination.

That is, the distal end portion 910, the upper pad 920, the thermal insulation pad 940, and the lower pad 930 are sequentially stacked. In this case, the hot melt 500 is respectively disposed between the

members

910, 920, 940, and 930. Further lamination is provided.

On the other hand, the

members

910, 920, 940, 930, as shown in the accompanying Figure 14 so that the distal end portion 910 and the upper pad 920 and the insulating pad 940 and the lower pad 930 are sequentially stacked from the upper side thereof. For example, but not limited to.

That is, in the state where the distal end portion 910 is disposed at the lowermost side, the upper pad 920, the insulation pad 940, and the lower pad 930 may be sequentially stacked on the upper side.

Next, an oven heating step S30 of applying heat to each of the

members

910, 920, 930, 940, and 950 stacked through the member stacking step S20 is performed.

The oven heating step S30 applies heat to each of the members stacked in the member stacking step S20 using an oven.

At this time, when the hot melt 500 is heated by high temperature heat, the hot melt 500 serves as an adhesive for bonding the members to each other while melting.

That is, the oven heating step S30 is a process of heating the hot melt 500 to bond the

members

910, 920, 930, 940, and 950.

Next, a cold press molding step S40 is performed to cool the heat while applying pressure to each of the

members

910, 920, 930, 940, and 950 heated through the oven heating step S30.

Cold press forming step (S40) is performed on the surface corresponding to the foot between the ball and the heel of the functional insole 1000 while performing the cold press processing of the product performing the oven heating step (S30) through the operation of the mold for cooling press. The protruding ball support portion 100 is formed to be formed.

The ball support portion 100 formed in the cold press forming step (S40) of the functional insole manufacturing method according to an embodiment of the present invention, when the igniter bends the metatarsal joints, the ball support portion 100 is the foot ball and the middle foot By supporting a part of the ground that is separated from the ground between the metatarsal joints, the body of the wearer located on the upper surface of the functional insole body provides a reaction force to the force to move upward and upward to improve the forward upper mobility. In order to, the ball supporting portion 100 is formed to protrude.

Description of the ball support portion 100 will be omitted because it overlaps with the description of the functional insole.

That is, by pressing and cooling under the influence of the pressing force by the cooling press and the cooling water flowing through the cooling press, the pressing and cooling are performed at the same time, it is possible to shorten the working time and to reduce the labor maneuver and thereby the manufacturing cost.

That is, the cold press molding step S40 is to form the functional insole 1000 by simultaneously cooling and compressing each of the

members

910, 920, 930, 940 and 950 heated in the oven heating step S30 at once. It would be possible.

In addition, when the cooling press processing is completed, the thermal insulation pad 940 is positioned between the upper pad 920 and the lower pad 930 to be kept blocked from the external environment, thereby maintaining the thermal insulation pad 940. In addition to preventing the contained airgel powder from being exposed to the outside, the thermal insulation pad 940 can completely preserve the thermal insulation by the airgel.

In particular, in the cooling press molding step (S40), the circumferential portion of the upper pad 920 and the lower pad 930 from the portion where the thickness of the functional insole is changed to the heel portion is the rear surface of the distal portion 910. It is desirable to be able to squeeze completely to the extent that it is exposed, thereby allowing accurate molding of the perimeter of the functional insole.

In addition, when the molding of the product is completed through the aforementioned cold press molding step (S40), the cutting step (S50) of cutting the product into separate insoles is performed, thereby manufacturing a functional insole according to an embodiment of the present invention. Is done.

Cutting step (S50) is to cut the product formed in the cold press forming step (S40) to separate the individual insoles.

At this time, it is important that the thermal insulation pad 940 is not exposed to the cut end surface.

As a result, the functional insole manufacturing method according to an embodiment of the present invention is provided as a thermal insulation pad 940 formed by impregnating the airgel powder in the nonwoven fabric rather than being attached to the shoe insole is provided as a heat insulating material made of airgel as a separate lamination product. The stack is provided together with the

other members

910, 920, 930, 940, and 950, and then press-molded through a batch heating and cooling press, so that the process for manufacturing the lamination product may be omitted.

That is, since the bottom surface of the upper pad 920 and the upper surface of the lower pad 930 replace the role of the lamination film to block the heat insulating pad 940 from the external environment, the heat insulating pad 940 is manufactured as a lamination product. There is no need to do this, thereby shortening the manufacturing time of the shoe insole.

In addition, since the cooling press process is performed, there is no need to wait for the heat of the product to cool down after the heat press process, thereby reducing the final production time of the product compared to the heat press process.

The insulation pad 940 prepared in the member preparation step S10 may be smaller than the upper pad 920 and the lower pad 930 cut in the cutting step S50.

That is, the insulating pad 940 is manufactured in a shape according to the use as described above, so that only a portion of the bottom of the shoe insole is provided in addition to the upper pad 920 and the lower pad 930. By being completely covered by the can be prevented from leaking the airgel powder contained in the thermal insulation pad 940 after the shoe insole is completed without packaging with a lamination film.

At this time, the surface of the hot melt 950, the lower pad 930 or the upper pad 920 adjacent to the insulating pad 940 prepared in the member preparing step (S10) to guide the seating position of the insulating pad 940 Instruction lines may be further provided.

In addition, an instruction line 310 for guiding a seating position of the insulation pad 940 is further provided on a surface adjacent to the insulation pad 940 of the hot melt 950, the lower pad 930, or the upper pad 920. It is preferred to provide.

That is, considering that the insulating pad 940 is provided with a specific shape while being smaller than the lower pad 930 or the upper pad 920, the hot melt 950 and the lower pad for mounting in the correct position. The insulating pad 940 is seated in the correct position by further forming an instruction line (see the dotted line in FIG. 2) on the surface adjacent to the insulating pad 940 of the 930 or the upper pad 920. This is to achieve a state.

Of course, in the member preparation step (S10) between the upper pad 920 and the distal end portion 910, a cushioning member (not shown) for cushioning when walking or other functional member (for example, a heating member) , Cushion member, etc.) may be further provided, and such a cushioning member or other functional member may be selected and provided according to its needs.

In particular, during the sequential stacking of the

members

910, 920, 930, 940, and 950, the thermal insulation pad 940 may be formed of the hot melt 950, the lower pad 930, or the upper pad 920. The sheet is stacked in accordance with the indication line 310 formed on the surface adjacent to the insulating pad 940.

In addition, the functional insole manufacturing method according to an embodiment of the present invention is smaller than the insulating pad 940 and the upper pad 920 and the lower pad 930, hot melt 950, lower pad 930 or upper On the surface adjacent to the thermal insulation pad 940 of the pad 920 is further provided an instruction line for guiding the seating position of the thermal insulation pad 940, so that the thermal insulation pad 940 can always be kept in position. Oven heating and cooling presses can be carried out through phosphorus lamination, thereby reducing manufacturing costs.

The upper pad 920 or the lower pad 930 prepared in the member preparation step S10 may be made of rubber, a rubber resin, a thermoplastic resin, a thermosetting resin, or a natural hardening resin.

That is, natural rubber, butadiene rubber, chloroprene rubber, isobutene-isoprene rubber, isoprene rubber, acrylonitrile-butadiene rubber, hydrogenate-nitrile rubber, styrene-butadiene rubber, polyacrylate rubber, ethylene-acryl rubber, chloro Sulfonate-polyethylene rubber, ethylene-propylene-diene rubber, ethylene-propylene rubber, fluorocarbon rubber, perfluorocarbon rubber, vinyl-methyl-silicone rubber, fluorosilicone rubber, epichlorohydrin rubber, polyester urethane , Polyetherurethane, thermoplastic polyester-ester rubber, halogenated butyl rubber, epoxidized natural rubber, polyvinylchloride, polymethylene methacrylate, ethylene propylene rubber, ethylene propylene diene monomer, polyethylene terephthalate, polytrimethylene terephthalate, Polybutylene Terephthalate, Polyethylenenaphthalate, Nylon 4 , Nylon 5, Nylon 6, Nylon 4,6, Nylon 6,6, Nylon 6,10, Nylon 6,12, Nylon 11,12, Aromatic Polyamide, Vinyl Ethylene Copolymer, Methyl Ethylene Copolymer, Ethyl Acrylic Acid Ethylene copolymer, Ethylene butyl acrylate copolymer, Ethylene acrylic acid copolymer, and Ethylene methyl methacrylate copolymer, Styrene butadiene random copolymer, Styrene butadiene styrene block copolymer, Styrene isoprene styrene block copolymer, Styrene butadiene butylene styrene block Copolymers, styrene ethylene butylene styrene block copolymers, styrene ethylene propylene block copolymers and styrene ethylene propylene styrene block copolymers, low density polyethylene, medium density polyethylene, high density polyethylene, linear low density polyethylene, ultra low density polyethylene, ultra high molecular weight polyethylene, homo Polypropylene, Block Polypropylene Copolymer, Random Poly Rhylene copolymer, random polypropylene terpolymer, polysiloxane, polysilane, polysilazane, phenol resin, epoxy resin, unsaturated polyester resin, melamine, polyurethane, polyimide, polyoxymethylene (polyacetal), polyether Ether ketones, polyphenylenesulfides, polyarylates, polyamideimides, polyetherimides, polysulfones, polyethersulfones, polyphthalamides, ethylene vinyl acetate and the like can be used.

The upper pad 920 and the lower pad 930 prepared in the member preparation step S10 are

Formed of the same or different materials, the auxiliary cushion pad may be characterized in that it is provided thinner than the main cushion pad.

That is, since the upper pad 920 is actually provided as a part for providing a cushion when walking, the upper pad 920 is formed to have a thickness sufficient to provide sufficient elasticity even if compression is performed by oven heating and cooling press processing. Considering that the lower pad 930 is a portion provided to substantially prevent external exposure of the thermal insulation pad 940, the lower pad 930 is formed to have a thickness sufficient to prevent tearing or internal exposure when compression is performed by a cold press process. Just do it. Of course, it is more preferable to form a thickness considering the wear on use.

However, of course, the lower pad 930 may be formed of a harder material than the upper pad 920 in consideration of the degree of wear as a part which contacts a substantially hard part.

The thermal insulation pad 940 prepared in the member preparation step S10 may be made by pressing the non-woven fabric in a state containing airgel powder and then cutting it into a desired shape.

In other words, it is not a structure that is completely packaged with a lamination film as in the prior art, but may be formed to maintain a specific shape.

Here, the desired shape (or specific shape) is a shape in consideration of the bottom surface of the shoe insole as shown in FIG. Of course, the shape of the thermal insulation pad 940 is formed to exist only in the front side or the rear side of the shoe insole, or formed to exist only in the center side of the shoe insole according to the use of the shoe insole, or shoe insole Of course, it can be formed in various ways, such as to exist only on the circumferential side of.

The cold press forming step (S40) of the functional insole manufacturing method according to an embodiment of the present invention is to form a toe support portion 200 is formed to protrude on the surface corresponding to the toe and the foot of the functional insole 1000 (See FIGS. 9 to 11).

The toe support part 200 (toe rear side) supports the ground of a predetermined part away from the ground between the toe and the foot ball, so that the body of the wearer located on the upper surface of the functional insole body reacts to the force of the toe to move in the front upper direction. To improve the forward upward movement force.

It is also necessary to minimize the energy lost after the heel lifter and just before the toe lifter. To this end, the toe support 200 may be formed on the functional insole body (see FIG. 9).

The present invention is not limited to the above-described embodiments, and the scope of application is not limited, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
