The present invention relates to an insole that is used for insoles of various footwear, and more particularly, to improve the intake of one side of the insole, while simplifying the manufacturing process as well as improving productivity and reducing costs and labor costs, Since the blockage of the intake part by foreign matter does not occur, the air insole for shoes having an antibacterial function of a feature that extends its use life semi-permanently.

In general, footwear has a form that seems to surround the entire foot of a person according to the human body structure, even though it is worn widely and for a long time in everyday life, so that the side of the wearer's toe is not able to communicate with the air smoothly, resulting in various side effects.

In other words, if you are wearing shoes for a long time or you are engaged in vigorous exercise or work, the moisture or sweat from your feet will not be discharged quickly and will accumulate inside the shoes. I am frequent.

Therefore, in recent years, various types of shoes have been proposed to overcome the above problems. However, due to the inherent limited design of the shoes, air communication is not smoothly performed on the toe of the wearer.

In addition, a separate insole has been proposed and used for air communication inside the shoe entering the root, the air-circulating insole as described above, as shown in Figure 1 as a whole, such as the flat shape of the shoe insole (Insole) It is provided with a soft insole made of a material, wherein the insole 100 is completed by heat-sealing the edge of the upper plate 101 and the lower plate 102 by high frequency,

The heel portion of the insole 100 is inserted into the sponge 103 having a fragrance material is formed, and in one middle portion of the insole 100 to form an intake means for sucking the outside air, from the intake means The incoming air is mixed with the fragrance material to be discharged to the front of the insole, ie deep inside the shoe.

At this time, the intake means is inserted into the air inlet side of the check valve 105 prior to the heat fusion process of the upper plate 101 and the lower plate 102 in the state that the entire circumferential surface except for the portion where the separator is inserted After the separation paper is removed, the PVC pipe 104 is inserted into the space in which the separation paper is inserted into the inlet side of the check valve 105 in the form of a tube and sealed with an adhesive liquid.

And the protective tube 106 for embedding the check valve 105 is inserted.

Accordingly, the outside air introduced through the PVC pipe 104 and the check valve 105 as described above is compressed by the sponge 103 by the user's walking, and the inside air passes through the flow path of the insole 100 itself. 107), which causes the inlet air to be discharged to the toe part, which is the deepest part of the shoe.

That is, the suction means is formed in the rear middle portion of the insole that is the easiest inflow of outside air while the inlet air is discharged to the toe of the user where the circulation of the air is not the least, the air circulation inside the shoe This improves the elimination of odors and enables the wearing of a comfortable state.

However, since the manufacturing process of the air-circulating insole as described above is quite complicated and requires a lot of steps, the economic burden due to the high cost of production is considerable. From the individual production process of the top plate and the bottom plate, which is produced separately, the intake means will be formed on the part where a separate separator is inserted and heat-sealed between the top plate and the bottom plate, and separated from the heat-sealed product. After removing the paper and removing the separator paper, the intake PVC pipe is manually inserted into the inlet side of the check valve by manual labor to fix it with adhesive liquid.When the intake means is completed, the surrounding and separation of the PVC pipe is completed. Extra gaps and spaces where paper is inserted are sealed by adhesive Which it would have to be a cumbersome process.

Therefore, the conventional insole manufacturing method having a large number of processes and steps as described above greatly reduces the productivity and requires a high cost of production, which leads to a considerable economic burden for both the manufacturer and the consumer, and is extremely unreasonable due to inappropriate mass production.

In particular, the intake means of the insole as described above is composed of a structure for sucking the outside air inwardly by the pipe protruding outward, the end is completely open and exposed toward the outside of the intake pipe, There is a problem that sand or foreign matter easily enters through the intake pipe. When foreign matter such as sand is introduced into the pipe, the foreign matter may block the inside of the pipe or prevent the smooth operation of the internal check valve. Therefore, the intake means is to prevent the original role.

As such, if the intake means does not perform its original role, the purpose of using the air-circulating insole itself is lost, which implies a very short lifespan compared to the expensive production and purchase cost.

The present invention has been made to improve the problems as described above, the melted air inlet portion on the middle of one side of the upper plate and the lower plate for fusion molding shoe insole, respectively, the inside of the air inlet and the protective tube and check In the state in which the valve and the semicircular metal intake pipe are respectively installed, the edges of the upper plate and the lower plate and the edges of the air inlet are simultaneously heat-sealed, and the natural suction of air is made through the micro-holes formed in the air inlet of the upper plate. ,

The production of air-circulating insoles with intake means is completed only by the heat-sealing process of the upper plate and the lower plate, which greatly increases the productivity by simplifying the manufacturing process. In addition to reducing labor costs and cost savings through mass production, the intake flow path through micro-pores can prevent the intake flow path from being blocked by foreign substances such as sand and prevent the loss of the function of the check valve. It is an object of the present invention to provide an air-circulating insole that greatly extends its service life.

In addition, another object of the present invention is to form a built-in fragrance or antibacterial agent between the upper plate and the lower plate in the position corresponding to the concave portion of the sole, the internal space is a fragrance or antibacterial agent and insole of the heel portion By connecting to the flow path toward the front lower portion, it is to increase the amount of air circulation as well as to significantly improve the antibacterial or odor effect accordingly.

Hereinafter, preferred embodiments of the present invention will be described.

Figure 3 is an overall perspective view of the air-circulating insole according to the present invention, Figure 4 is a plan view of the overall air insole according to the present invention, Figure 5 is a detailed cross-sectional view of the intake portion of the air-circulating insole according to the present invention. .

The upper plate 10 and the lower plate 20 formed of a soft elastic material is formed by heat-sealing the edge of the lower plate 20, but the heel portion of the upper plate 10 is formed by the upwardly fused space 11 is compressed to this Built-in sponge 12, and formed intake means having a check valve in the middle portion of the upper plate 10 and the lower plate 20, introduced through the intake means by the pumping action by the compressed sponge 12 In the air-circulating insole in which air is discharged through the flow path 13 to the discharge hole 21 in the lower end of the insole,

An upwardly fusing part 14 and an air inlet part 15 are formed in one middle part of the upper plate 10, and one side of the lower plate 20 is joined to the air inlet part 15 in a corresponding form. A protruding portion 22 is formed, and a protective tube 17 having a tube-shaped check valve 16 is inserted into the fusing portion 14, and one end of the check valve 16 has a semicircular metal material. The intake pipe 18 is inserted so that the intake pipe 18 is positioned between the air inlet 15 and the junction 22,

The edges of the air inlet part 15 and the joint part 22 are thermally fused to each other through heat fusion of the upper plate 10 and the lower plate 20, so that the air inlet part 15 is pumped when the compressed sponge 12 is pumped. It is configured to allow the outside air through the inlet pipe 18 and the check valve 16 to be sucked into the inner passage 13 through the upper and downward through the micro-pores 19, 19 '.

In addition, in the middle of the upper plate 10 and the lower plate 20 corresponding to the concave portion of the sole is formed a separate receiving portion 30 in the form of fusion, antibacterial action or odor inside the receiving portion 30 Insert the fragrance or antimicrobial agent 31 containing the material,

One side of the accommodating part 30 is in communication with the fusing part 14 in which the intake means is built, and the other side of the accommodating part 30 is connected to the flow path 13 so that the compressed sponge (when walking) The pumping action of 12) and the pumping action by the fragrance or antimicrobial agent 31 may be configured to have a high air circulation action, antibacterial or fragrance dissipation function.

In particular, the entire surface of the upper plate 10 and the lower plate 20 except for the space 11, the fusion unit 14, and the flow path 13 is formed in a lattice form by heat-sealing lines 32 and 32 ′. By forming the divided air filling parts 33 and 33 ', the air filling parts 33 and 33' in a sealed state may be configured to have a superior cushioning action and a feeling of wearing.

Referring to the action of the air circulation insole for shoes having the present invention antimicrobial function as described above in more detail by the accompanying drawings as follows.

As shown in the drawing, the air-circulating insole according to the present invention is formed by joining and molding the upper plate 10 and the lower plate 20 made of soft elastic materials, respectively, by thermal fusion using high frequency in the state where they are separately formed. Sponge and the intake means and the discharge hole for the pumping action of the user walking is formed.

In this case, in order to form the intake means described above, after the separation of the separation paper from the fusion molding and the molded product in the state of inserting a separate separator, the PVC pipe, which is the intake means, is inserted into the removal unit by manual operation. Since the finishing process using the adhesive solution, etc., the work process is many and complicated, as well as the problems such as loss of function due to foreign substances introduced through the intake pipe, the present invention is to improve the intake means described above to overcome this.

That is, the fusing part 14 and the air inlet part 15 are respectively formed in one middle part of the upper plate 10, and the one side middle part of the lower plate 20 corresponding to this corresponds to the air inlet part 15 described above. A junction 22 having a position and a corresponding shape is formed, but the air inlet 15 has a plurality of micro-holes 19, 19 'which are perforated upward and downward.

In such a state, a protective tube 17 having a relatively rigid physical property is inserted into the inside of the fusing part 14, and a check valve 16 in the form of a thin tube is built into the protective tube 17. One side of the check valve 16 may be coupled to an intake pipe 18 made of a semi-circular metal material, and the intake pipe 18 is located between the air inlet 15 and the junction 22. .

In this state, when the edges of the upper plate 10 and the lower plate 20 and the edges of the air inlet part 15 and the bonding part 22 are simultaneously fused at high frequency, the upper plate 10 and the lower plate 20 are joined together as a whole. It is possible to complete the insole in the state, the upper side of the heel portion of the upper side of the heel portion is a compression sponge 12 is inserted into the interior of the space 11 is built.

Therefore, when the insole is inserted into the shoe and the user walks while wearing the shoe, the heel of the user repeatedly presses the compression sponge 12, thereby pumping the space 11. The outside air is sucked from the intake means by the pressure difference due to the pumping, and the sucked air moves to the tip of the insole through the flow path 13 formed in the insole, and discharges the end of the flow path 13. Through the ball 21 is to discharge the outside air deep inside the shoe.

That is, when the internal flow path 13 is in a low pressure state due to the pumping action of the compressed sponge 12 and the space part 11, the micro-pores 19 and 19 formed in the air inlet part 15 of the upper plate 10. ') Through the outside air is introduced into the flow path 13 through the intake pipe 18 and the check valve 16 made of a semi-circular metal material, the compressed air of the compressed sponge 12 is released At the same time, the entire interior of the flow passage 13 and the compressed sponge 12 are filled in the space 11 therein.

In such a state, when the space 11 is pressed by walking, the air therein is not discharged to the intake means by the check valve 16, so only through the discharge hole 21 at the end of the flow path 13. As a result, it will continue to provide fresh outside air deep into the inside of the shoe.

Therefore, as described above, since the air circulation type insole which does not require any post-working is completed by simple heat fusion operation of the upper plate 10 and the lower plate 20, the work process is greatly shortened, so that mass production is possible, and the labor cost is greatly reduced. Cost reduction is possible.

In addition, the micro-holes 19, 19 'of the air inlet 15 to suck the outside air is always maintained since its shape is maintained even under pressure from the user through the semi-circular metal intake pipe 18 therein. It is possible to inhale the air smoothly, and the possibility of introducing foreign substances such as sand is greatly reduced by the size of the intake hole, which is relatively reduced, and the service life thereof is extended. In the case of the internal check valve 16, While it is hardly affected by the operation, when a relatively large foreign material such as sand is introduced, problems may occur in the opening and closing action of the tube in the form of a thin film. By forming a large number (19 '), the problem of loss of function due to foreign matter such as sand is effectively overcome without affecting the intake amount.

In addition, the air circulation insole of the present invention may be configured so that the fragrance is emitted to the air discharged along with the doubling of the amount of air circulation in the shoe, the top plate 10 is a position corresponding to the concave portion of the sole as shown in FIG. And forming a receiving portion 30 in the form of a melt in the lower plate 20, and inserting the fragrance or antimicrobial agent 31 containing a fragrance material in the inner portion of the receiving portion 30 to produce the insole, One side of the accommodating part 30 is to pass through each other with the inlet means 14, the intake means and the other side of the accommodating part 30 to be connected to the flow path 13,

Air introduced from the outside by the pumping action of the compressed sponge 12 is filled into the inside of the receiving portion 30 and the air in the charged state is discharged along the flow path 13 by the pumping action to the flow path 13 It is discharged into the shoe through the discharge hole 21 of the end.

Therefore, the inflow air is to include the fragrance component in contact with the fragrance or the antimicrobial agent 31 having a fragrance material, such air is to always produce a odor in the shoe as it is discharged into the shoe.

In particular, when the wearer walks, the pumping action by the compression sponge 12 as well as the pumping action by the fragrance or the antimicrobial agent 31 is performed at the same time, so that the intake amount is greatly increased and the air circulation in the shoe is greatly increased. As the air circulation increases, more comfortable shoes can be maintained.

In addition, the entire upper portion of the upper plate 10 and the lower plate 20 is formed of a grid-like air filling portion 33 (33 ') divided by heat-sealing lines 32, 32', air in a sealed state The charging part 33 (33 ') further improves the elasticity and elasticity of the insole itself, thereby reducing the feeling of wearing and walking fatigue, thereby enabling more rational and convenient use.

The air circulation insole for the shoe having the present invention antibacterial function as described above, the production of the air-circulating insole having the intake means only by the heat-sealing process of the upper plate and the lower plate is to greatly increase the productivity through the simplification of the manufacturing process, It is possible to maintain uniform and stable quality because there is no need for finishing process that was dependent on manual work, and it is possible to realize cost reduction through labor reduction and mass production, and intake by foreign matter such as sand by intake method through micro-perforation. It is possible to prevent the flow path from clogging or the function of the check valve, so that the service life is greatly extended. The fragrance or antimicrobial agent embedded between the upper and lower plates is formed at the position corresponding to the recess of the sole. The internal space is directed towards the heel fragrance or antimicrobial agent and the lower part of the insole. To be connected to the flow path, increase in the air circulation is, of course, that it fragrance or antimicrobial effect is significantly improved according.
