Description

Shoe insole {INSOL FOR SHOES}

The present invention relates to a shoe insole, and more particularly, the insole which is located at the top of the shoe and directly connected to the user's foot is molded at a low temperature so that the foot can be deformed according to the bend and shape of the user's foot so as to keep the foot stable. An improved shoe insole is provided.

In general, the shoe insole is one of the important shoe components that are located on the inner top layer of the shoe directly connected to the sole of the user to support the foot.

Conventionally, insoles (soles) for shoes having various functions have been known, but these are generally formed according to shoe size (size), not according to the shape of the sole of the wearer, and thus standardized foot size without considering the physical condition of the user. Since it is pre-molded to fit the foot, the sole can not be in close contact with the insole when worn for a long time, so it will easily bring fatigue.

In addition, as another example of the insole, because it is in close contact with the foot, there are a number of functional insoles to remove the odor caused by sweat or water, increase the absorption of moisture and release the beneficial ingredients to the human body to contribute to health promotion However, this is far from the purpose of reducing the fatigue of the foot because it is not a function to maintain a stable according to the shape of the foot directly connected.

The foot of the human body has a long arch shape that extends from the heel bone to the base of the metatarsal bone just behind the big toe joint in the skeletal structure, and the midfoot arch of the arch shape at the bottom of the foot is the ball of the foot of the foot Along the site, the dome has a slightly curved shape, which is called an arched arch.

In this way, the foot is largely composed of the heel, the foot, and the sole of the foot, and since the foot is formed differently according to the physical condition of the individual, the insole and the foot exactly match when wearing a preformed insole with an average or standard calculated dimension. It does not have a problem that wear is reduced and fatigue occurs.

In order to solve the problems described above, it has been developed and used to reduce the fatigue even if worn for a long time while increasing the wearing comfort by molding the insole to fit the user's body (foot), a representative example is shown in FIG. Utility Model Registration No. 435458.

Looking at the contents of the prior art as described above, the upper layer of the insole body (1) is a fiber layer (2), the middle layer is a polyurethane layer (3) and the lower layer is an EVA layer (4) it is an adhesive It is configured by adhesive molding, and heated to 70 ~ 110 ℃ and put into the wearer's shoes after 5 minutes is configured to be custom molded to the shape corresponding to the sole shape of the wearer.

This prior art forms an insole in the same shape as a general insole, but further forms a polyurethane layer and Yves layer, exposes the polyurethane layer and Yves layer to high temperature, inserts the insole into the shoe, and then When worn, the polyurethane layer and Yves layer are deformed by the load of the user.

However, in the prior art, since the polyurethane layer and the YB layer are formed only by planar bending due to high heat, the insole is formed (deformed) due to high temperature and load because the gap between the foot and the shoe is not sufficiently filled. You will not be able to limit your foot movements even after you have done so.

In addition, since the insole having a polyurethane layer and Yves layer is exposed to high temperature and deforms due to load, it only responds to the shape of the insole and the foot, so that the gap between the foot and the foot is not completely prevented. It is not possible to faithfully achieve the basic purpose to improve the fit or to reduce the fatigue of the foot when worn for a long time.

In particular, the insole to which the prior art is applied has the same configuration as the existing insole having a uniform shape having a thick heel portion and the foot portion and a thin thickness of the sole portion, and further includes a polyurethane layer and Yves layer to be moldable by high heat. Since only a polyurethane layer and Yves layer are formed by high heat, it is only a part of deformation and does not function to fill a space between a foot and a shoe.

In addition, when the insole is to be accommodated in the shoe to wear shoes, it is inconvenient to be worn only in a place where there is a means such as a hot air fan or a microwave oven that can generate high heat all the time. There are many problems, such as higher costs.

Accordingly, the present invention is invented to solve the problems described above, and formed on the upper surface of the molding layer and the molding layer made of EVA (EVA) which is connected to the inner bottom of the shoe and molded in response to low temperature or body temperature of the body. The surface layer is formed to improve the touch when the foot is in contact with the foot, and is formed on the bottom surface of the molding layer and molded to fit the shape of the user's foot flexion and the shape of the inside of the shoe by the low temperature heat or the body heat. It is made of a molding structure to fill the space between the shoe and the foot while maintaining a stable foot of the user;

By having a structure that can be molded at a low temperature according to the shape of shoes and feet, it is possible to keep the foot stable to fit the body shape by simply wearing shoes, to prevent foot ankle phenomenon, to reduce the fatigue of the foot, and to break down the foot arch. Due to this, it is possible to achieve the purpose of performing a correction function that can prevent going to the feet and knees and maintain the correct posture.

The present invention can reduce the fatigue of the foot while increasing the fit by blocking the flow of the inside of the shoe at the source by filling the space between the foot and the shoe while being molded to fit the shape of the foot in response to a low temperature around 30 ℃, such as body temperature Of course, it is an invention having various effects, such as providing a high-quality shoes while reducing the cost of insoles and providing ease of manufacture and eventually reducing the overall production cost of the shoes.

Footwear insole 100 to which the technique of the present invention is applied is in contact with the inner bottom of the shoe 101 is molded in response to a low temperature such as a temperature of 40 ~ 60 ℃ or the body (heat generated by body temperature or foot movement of the foot) A molding layer 103 made of EVA is formed.

The upper surface of the shaping layer 103 is formed by forming a surface layer 104 attached with a fiber or fabric material so as to improve the feel of contact with the foot, and the bottom of the shaping layer 103 inside the shoe 101 It is characterized in that it has a molding structure to be molded (deformed) in accordance with the shape of the user's foot and the shape of the inside of the shoe in a low temperature heat or body heat in the state located in.

The thickness of the insole 100 is preferably to have a thickness of about 5 mm as a whole can give a suitable change in accordance with the shape of the foot during low temperature thermoforming, if the thickness of the insole 100 is too thin or too thick This is not good because it is difficult to mold.

The molding structure is such that the left side (LF) has a shape lower than the right side (RF) on the basis of the diagonal line 105 connected from the right middle position of the heel to the left middle position of the sole on the bottom of the insole 100 When the insole 100 is molded to maintain the same shape as the foot.

The range of the lower left side LF lower than the right side RF may be 2.5 mm or less in consideration of the thickness of the forming layer 103 to prevent excessive deformation of the insole 100 in the forming process.

At the bottom heel position of the insole 100, the insole 100 is in close contact with the heel during molding, so that the center portion of the indentation 106 having an arc shape so that the space between the heel and the shoe 101 can be easily filled. The inclined portion 110 is formed from both lower end portions 107 of the concave portion 106 to both end portions 108 of the insole 100.

At the bottom foot arch position of the insole 100, a steep slope 112 is formed from the left end 111 of the insole 100 to the bottom of the insole 100, and a lower end 113 of the steep slope 112. To the bottom center position of the insole 100 to form a horizontal portion 114, and from the end of the horizontal portion 114 to the right end 115 of the insole 100 relatively inclined slope than the steep slope 112 Forming a gentle portion 116 to form a so that the steep slope 112 and the horizontal portion 114 during the molding so as to sufficiently support the foot arch.

In the bottom sole position of the insole 100, a horizontal portion 117 is formed in a flat shape as a whole, and both ends 108 of the insole 100 from the bottom end portions 118 of the horizontal portion 117 are formed at the time of molding. The insole 100 is configured to form the inclined portion 119 so that the space of the shoe 101 can be easily deformed while the edge of the foot is thanked.

Looking at the process of using the insole 100 applied to the technology of the present invention as described above in the shoe 101 as follows.

First, the insole 100 is stored inside the shoe 101, and the user wears it as it is, or applies a low temperature hot air using a hair dryer or the like, and then wears the shoe 101 in a conventional manner.

Then, the insole 100, in particular Yves A, due to the pressing force of the foot 102 together with the walking or running behavior or exercise or the low temperature applied artificially to the insole 100 while wearing the temperature of the foot 102 or shoes As the molded layer 103 is deformed and forms a form surrounding the foot, deformation (molding) is made to fill the space inside the foot 102 and the shoe 101.

As such, when the shaping layer 103 of the insole 100 is deformed due to the temperature of the foot 102 or artificial low temperature (40 to 60 ° C.), the deformation characteristics of the shaping layer 103 and the load and temperature of the foot 102 are determined. The shape of the shaping layer 103 constituting the insole 100 is not limited to the shape of the insole 100. Therefore, the foot 102 and the shoe 101 are formed in close contact with the foot 102. It will fill the space between them.

On the bottom of the insole 100, the insole 100 has a lower shape than the right side RF based on the diagonal line 105 connected from the right middle position of the heel to the left middle position of the sole. When molding (deformation) it is possible to maintain the same shape as the foot.

The insole 100 has a concave inlet portion 106 formed at the center of the bottom heel position and an inclined portion 110 is formed at both sides of the concave inlet 106 so that the insole 100 is in close contact with the heel of the foot during the molding process. It is to be able to easily fill the space between the heel 102 and the shoe (101).

The steep slope 112 is formed at the left end 111 of the bottom foot arch portion of the insole 100, and a horizontal portion 114 is formed from the steep slope 112 to the bottom center position of the insole 100. From 114 to the bottom of the insole 100 forms a gentle portion 116, the steep slope 112 and the horizontal portion 114 in the molding process can sufficiently support the foot arch portion, of course, the foot 102 And the space of the shoe 101 will be filled.

In the bottom sole position of the insole 100, a horizontal portion 117 having a flat shape as a whole is formed, and an inclined portion 119 is formed at both ends 118 of the horizontal portion 117 to form the foot 102. While comfortably supporting, the inclined portion 119 is located between the shoe 101 and the foot 102 to fill the space, so the insole 100 finally maintains the foot 102 in the shoe 102 while remaining stable. The foot 102 will be prevented from flowing.

In addition, the insole 100 is stored in a flat state without deformation at all, and then molded in such a manner that low temperature hot air is applied to the insole 100. However, fine deformation is applied through primary molding by applying low temperature hot air to the insole. After it is stored in the shoe may be completed by the low temperature hot air or the temperature of the foot or the heat generated in the process of moving in the state of wearing the shoe.

The present invention has a structure that can be molded at least once while the insole can be molded at a low temperature in accordance with the shape of the shoe and the foot can be kept stable to fit the body simply by wearing shoes, to prevent the ankle of the ankle phenomenon It is an invention having various advantages, such as reducing the fatigue of the foot and preventing the foot and knee from going down due to the impact of the foot arch and performing a corrective function to maintain a correct posture.
