Description

Insole in shoes for ventilation by air pumping}

The present invention relates to a breathable insole.

In detail, the present invention enables the ventilation inside the shoe by continuously venting the air outside the shoe to the inside by the air pumping function of the shoe insole when walking through a simple configuration without a separate device to increase the temperature inside the shoe It relates to a breathable insole that lowers, prevents diseases such as athlete's foot or eczema and maintains a clean and hygienic environment at all times.

Insole refers to a footrest made of urethane, rubber or leather that is in close contact with the inner bottom of the shoe. Shoe insoles reduce the fatigue of the soles of the wearer's weight. In particular, the insole protects the wearer's foot by relieving the impact of the sole during walking, and is usually adapted to the shape of the foot of the user while the user wears and uses the shoe.

On the other hand, the upper of the shoe is the outer cover covering the foot of the wearer, most of the shoes except sandals (sandal) is surrounded by the inside of the shoe as the upper.

However, since the inside of the shoe is wrapped in the upper and the shoe insole, ventilation may not be performed smoothly, and odor may be generated. In addition, since the inside of the shoe is an environment sealed by uppers such as leather and synthetic fibers, an undesirable sanitary environment is created by sweat and heat generated during exercise or walking. In addition, since the shock absorption is different depending on the material of the outsole (outsole) may be increased fatigue.

Ventilated uppers are already well known to solve the above problems. For example, shoes that attempt to ventilate the inside by using a Goretex fabric or a mesh upper with excellent breathability have been well known.

However, since breathable materials such as Gore-Tex fabrics are mostly expensive, manufacturing costs increase. In addition, even if the upper with excellent breathability diarrhea is limited to ventilate the inside of the shoe only by the upper. In addition, mesh uppers should adopt a separate reinforcement or reinforcement to solve the load bearing problem due to elasticity.

In addition, a variety of shoe insoles are known to ventilate the inside of the shoe by improving the internal structure, the known conventional insoles usually take a curved structure to expand the insole by the load of the body and flow air In addition to this method, a method of installing a check valve in the upper to discharge the flow of internal air out, or by installing an air vent in the out-sole to direct the inside and outside of the shoe, etc. have.

However, these methods have a cost increase factor by attaching a separate accessory, and the process is complicated or the effect of the simple flow of the internal air, not the internal injection effect of the external air, is to be obtained. In addition, dirt enters or water enters in rainy weather, so practicality is low and the ventilation effect is inevitably small.

On the other hand, registered utility model No. 0278189 incorporates several open-type air extruded valve bodies in the body weight acting portion located on the heel when walking to discharge the air to the rear of the shoes through the valve bodies to allow ventilation by air pumping shoes. Initiate.

However, the registered utility model No. 0278189 has a hole for air discharge in the rear of the shoe. Therefore, there is a problem that rain water can penetrate through the rain outlet. In addition, since the outlet can be easily blocked by mud or the like, the original purpose of ventilating the inside of the shoe cannot be achieved. In addition, since the air extrusion valve body is integral with the shoe and formed in the shoe outsole, it is difficult to manufacture. And it cannot be applied to dress shoes without elasticity in the outsole.

The present invention has been made in view of the above problems and to solve this problem, the present invention has a structure different from the conventional insoles for ventilation and a breathable insole that can easily ventilate the air inside the shoe with a simple configuration To start.

That is, an object of the present invention is to provide a breathable insole that can continuously ventilate the air inside the shoe while walking while sufficiently resisting the load without a separate device. That is, an object of the present invention is to provide a breathable insole that can implement a ventilation function and a buffer function at the same time.

Another object of the present invention is to provide a breathable insole that can lower the temperature inside the shoe, prevent diseases such as athlete's foot or eczema, and create a clean and hygienic environment at all times.

The purpose of the present invention is not limited to the above-described purposes, and other objects of the present invention, which are not mentioned above, will be clearly understood by those skilled in the art from the following description.

Breathable insole 100 of the present invention can be easily manufactured using injection molding, and preferably is formed in a front and back high shape. Injection molding is useful because it is inexpensive, the process is simple, and the wear resistance of the product can be secured.

A mold for each shoe size is manufactured and an insole for each size is manufactured using the mold. For example, after forming a mold of the elastic upper plate 20 and the lower plate 10 to be elastic and using the same to form the lower plate 10 and the upper plate 20, the upper plate 20 on the upper surface of the lower plate 10 ) Can be manufactured by bonding the insole 100 in all directions.

The intake passage 11 is formed at the rear end of the lower plate 10. Preferably, as shown in FIG. 4, the intake passage 11 has a wider width (ｗ1) of the tip portion than the width of the rear end portion (ｗ1> ｗ2), and a height (ｈ1) of the tip portion at the rear end. It is higher than the height of wealth (ｈ2) (ｈ1 ＞ ｈ2). That is, the intake passage 11 generally has the shape of the front and rear low and the front light narrow, and the front end thereof has a first height at a predetermined height from the bottom surface of the intake passage 11. The meat part 19 is raised.

The raised first thick portion 19 is formed in a gentle arc shape whose upper surface is gradually lowered from both sides toward the center portion, and is formed by protruding a predetermined height from the lower surface at the tip of the intake air 11.

The first thick portion 19 has a front inclined surface 19a and a rear inclined surface 19b. The rear inclined surface 19b is preferably formed to be relatively more gentle than the front inclined surface 19a to prevent the reverse flow of air introduced from the outside and to guide the forward flow of the introduced air.

When the insole is manufactured when the upper plate 20 is bonded to the lower plate 10, a gap is formed between the lower surface of the upper plate 20 and the upper surface of the first thick portion 19 so that the introduced air flows.

If the user's walking is a normal step (field walking, field legs), the first load is applied to the site of the foot is the rear outer side of the shoe insole 100, the inner leg (eye walking) is the rear inner side. In consideration of this, the intake passage 11 of the present invention is preferably formed at the rear end outer portion of the lower plate 10. That is, the intake passage 11 is preferably formed to be eccentrically spaced apart from the longitudinal center line A-A 'of the insole 100 by a predetermined distance e. In addition, the intake passage 11 may be formed in the rear end inner side of the lower plate 10 in consideration of the inner leg, and the formation position thereof is not limited to the above description.

A concave inlet 12 is formed in front of the intake passage 11. The concave inlet 12 is drawn downward from the front of the intake passage 11, is formed in the rear portion of the lower plate 10, and communicates with the intake passage 11. At least one buffer column is raised from the lower surface of the recess 12.

When the upper column 20 and the lower plate 10 are bonded to each other, the buffer column 12a adheres to the lower surface of the upper plate 20 to support the load.

In front of the concave portion 12, several elongated exhaust passages 14a, 14b, 14c, 14d are formed. The exhaust passages 14a, 14b, 14c, and 14d are arranged in front of the concave portion 12 and communicate with the concave portion 12. Four exhaust paths 14a, 14b, 14c, and 14d are preferably provided for discharging the sucked air between the toes of the shoe wearer, the leading end of which is located between the toes of the shoe wearer, respectively.

Fig. 6 is an enlarged perspective view showing the exhaust passage and the second thick portion of the present invention, and Fig. 7 is a sectional view taken along the line CC of Fig. 6. As shown in the drawing, the second thick portion 13 for preventing backflow is raised at the rear end portions of the exhaust passages 14a, 14b, 14c, and 14d communicating with the concave portion 12. Like the first thick portion 19, the second thick portion 13 is for preventing the backflow of air and guiding the air flow toward the discharge hole 21. As shown, one pair of second thick parts 13 are allocated to each of the pair of exhaust paths 14a, 14b, 14c, and 14d, but this is only an example, and the example of forming the second thick parts 13 is Similar to / identical to the first thick portion 19. For example, the rear inclined surface 13b is gentle compared to the front inclined surface 13a in order to prevent backflow of air flowing from the concave portion 12 and to guide the smooth flow.

The first thick portion 19 and the second thick portion 13 of the present invention are used as check valves for guiding and controlling the flow of air, and both the lower surface and the exhaust passage 14a and 14b of the intake passage 11 are respectively. And 14c and 14d are extended from the lower surface and raised. In addition, when the lower plate 10 and the upper plate 20 are bonded to each other, the first thick portion 19 and the second thick portion 13 are close to the lower surface of the upper plate 20, but are not normally adhered to each other to allow air flow. Gaps are formed.

The lower surface of the upper plate 20 is adhered to the upper surface of the lower plate 10 having the above configuration to complete the shoe insole 100 of the present invention. At this time, it is preferable that the shoe insole 100 of the present invention has a thicker thickness of the rear portion than the entire thickness of the front portion so as to form a front and rear high shape as a whole.

Discharge holes 21 are formed at the front of the upper plate 20, and the discharge holes 21 are preferably provided in four so as to correspond to the respective exhaust passages 14a, 14b, 14c, and 14d. Located at the top of the furnace 14a, 14b, 14c, 14d. In addition, the discharge hole 21 is preferably located at the bottom joint between each toe to maximize the air circulation effect without being closed by the sole. Then, the thickness of the top plate 20 is properly maintained so that the wearer does not feel the heterogeneity due to the shock absorbing column 12a. The shock absorbing column 12a can be prevented from interfering with the flow during intake of the outside air, and on the other hand, can be changed into an appropriate shape according to the use or size of the shoe in consideration of the exhaust and buffering effects, and the arrangement position and quantity thereof are variable Should be considered as possible.

8 to 11 is a detailed view showing the flow of air at the time of heel landing, heel landing, heel separation, heel separation in the present invention, the following Table 1 is an analysis of the average number of walking and the time required , Ventilation action of the breathable shoe insole 100 of the present invention made as described above can be seen that the three steps of compression, exhaust, intake is circulated according to the wearer's walking.

8 shows the flow of air upon heel landing. At the heel landing, the first thick portion 19 is closed while the rear portion of the shoe insole 100 is pressed by the weight of the wearer. At the same time the buffer column 12a is compressed to support the load by the weight to perform a buffer function. The second thick portion 13 is open because no load is applied. At the same time as the heel landing, the air in the concave portion 12 flows forward along the exhaust paths 14a, 14b, 14c, and 14d and is discharged into the shoe through the discharge hole 21. At this time, an additional temporary buffering effect can be obtained by the internal air pressure in the recess 12.

9 shows the flow of air upon landing the heel. As shown in the drawing, the remaining air in the concave inlet 12 is compressed and completely flows out through the discharge hole 21 along the exhaust paths 14a, 14b, 14c, and 14d. In addition, in the state where the first thick portion 19 is closed, most of the remaining air in the concave portion 12 is discharged, and the remaining air in the exhaust passages 14a, 14b, 14c, 14d is compressed and discharged in small amounts. After landing on the heel, the weight is gradually loaded on the second thick portion 13, and the second thick portion 13 is closed, and a small amount of air remaining in all of the exhaust passages 14a, 14b, 14c, and 14d is discharged.

10 shows the flow of air upon heel removal. As shown, when the heel is removed, the first thick portion 19 is opened and the second thick portion 13 is completely closed while the wearer's load is moved to the front of the insole 100. At the same time, while the compressed buffer column 12a in the concave portion 12 is restored to its original state, the outside air is taken in through the first thick portion 19 opened by the internal pressure drop according to the restoration.

In the above-described configuration of the present invention, the first thick portion to the second thick portion repeatedly perform air intake, flow, and discharge in one direction according to the change in landing motion of the foot during walking. Since it is presented as one of the shapes for the corresponding component performing the same function, even if the shape is to be changed within the scope of the present invention.

Figure 11 shows the state of flow of air at the heel separation. As shown, at the time of separating the heel, while the buffer column 12a formed inside the concave inlet 12 is restored to the maximum, the air intake amount reaches a maximum. The intake air is introduced into the exhaust paths 14a, 14b, 14c, and 14d, and the intake of the outside air is completed.

As a result, one walk is completed and the steps are circulated to allow the inside of the shoe to be ventilated and at the same time to obtain a buffer effect.
