Humans do not touch the whole foot when walking, the calf body portion 101 (foot hindgum) and the middle bone 105 (the part close to the toe of the sole) is the part where the most loads, the most loads are applied to these two parts All.

Hereinafter, the configuration of various embodiments of the shoe insole according to the present invention will be described in detail with reference to the drawings.

1st Example

1 is a perspective view of the configuration of the shoe insole 110 according to the first embodiment of the present invention, Figure 2 is an exploded perspective view of the configuration of the shoe insole 110 according to the first embodiment of the present invention It is.

Shoe insole 110 is to be mounted on the bottom surface of the inside of the shoe is to be used for improving the wearer's wearing comfort and foot protection.

Skeleton of the shoe insole 110 is formed by the body (111). The body 111 is formed of a material having an elastic force, such as rubber, is formed to facilitate its deformation. The shape of the body 111 may be manufactured to suit the size, shape of the shoe to be mounted.

First and second absorbing layers 113 and 115 are formed on the upper surface of the body 111. The first and second absorbent layers 113 and 115 protrude more than the upper surface of the body 111 to absorb shocks applied to the foot when walking.

When the wearer wears shoes, the first absorbent layer 113 is formed from a portion of the arch to the heel of the foot. The first absorbing layer 113 may be formed of a material having a relatively larger elastic force than that of the body 111, that is, relatively elastic deformation.

In addition, the first absorbing layer 113 may be formed of a memory foam that is restored to its original state when the pressure is removed. This is because the shape of the sole is different for each person so that it can be elastically deformed for each foot. In the case of general elastic materials, the shape loses elastic force and is permanently deformed as time passes. to be. In addition, since the memory foam is a porous material, it is possible to obtain a ventilation effect to prevent the odor in the shoes to some extent.

When the wearer wears shoes, the second absorbing layer 115 is formed from a portion forming the boundary of the sole and the toe to a portion forming the boundary of the arch. Like the first absorbing layer 113, the second absorbing layer 115 may be formed of a material that is relatively easy to elastically deform than the body 111, and may be formed of a memory foam material.

The first and second absorbent layers 113 and 115 compensate for some of the excessive burden on the hind paws and soles of the foot, which are most loaded when the pedestrian is walking. Fibrosis appears in the tissues around the interstem nerve, which is a branch of the internal and external plantar nerves, which causes pain in the forefoot. In addition, it is possible to prevent the lower back diseases such as lumbar disc, stenosis, separation dislocation due to the impact during walking, or to help the walking of the lower back patients to increase the recovery speed. In addition, the growth of the child can be seen to reduce the impact and give a moderate stimulation effect to help the growth period, it can also prevent joint damage in childhood.

In addition, in the case of flat feet, the entire sole of the foot is in contact with the sole of the shoe, so that the load and impact cause inflammation of the plantar ligament, heel pain, tendon inflammation, toe hump, etc. Easily exposed to the disease, the shoe insole 110 according to the present invention can effectively absorb the load of the first and second absorbent layers 113 and 115 has the effect of preventing such a disease.

Referring to FIG. 3, the body 111 is largely composed of a lower plate 111a, an absorption plate 111b, and an upper plate 111c.

The lower plate 111a is formed in a shape corresponding to the bottom surface of the shoe to be mounted as a part mounted in contact with the bottom surface of the shoe.

The absorption plate 111b is coupled to the upper surface of the lower plate 111a. The absorption plate 111b is formed of the same material as the first and second absorption layers 113 and 115 so that the first and second absorption layers 113 and 115 protrude from the upper surface thereof.

The upper plate 111c is coupled to an upper surface of the absorption plate 111b. The upper plate 111c is a portion where the sole of the wearer comes into contact with the top plate 111c. First and second through holes 117 and 119 are formed in the absorption plate 111b so as to penetrate in a shape corresponding to the first and second absorption layers 113 and 115 at positions corresponding to the first and second absorption layers 113 and 115. Is formed. The first and second through holes 117 and 119 are formed to allow the first and second absorbing layers 113 and 115 to protrude therethrough.

The manufacturing of the body 111 as three separate objects as described above is to facilitate coupling since the first and second absorbing layers 113 and 115 are formed of a different material from the body 111. The upper plate 111c, the absorption plate 111b and the lower plate 111a may be combined with an adhesive.

Second Example

Figure 4a is a perspective view of the configuration of a shoe insole according to a second embodiment of the present invention.

The shoe insole 210 is composed of a body 211 and a first absorbent layer 213 and a second absorbent layer 215 formed to protrude from the upper surface thereof.

An arch support portion 217 is formed to further protrude from the upper surface of the second absorbing layer 215. The arch support portion protrudes from a portion where the arch of the foot is in contact with the second absorbent layer 215. The arch support portion 217 is in contact with the arch to support the arch portion when walking to serve to distribute the load to the power generating body.

In addition, the arch support 217 serves to treat plantar fasciitis by stimulating the arch portion. Plantar fasciitis is an inflammation of the band-like plantar ligament of thick fibrous tissue that connects from the toes to the heel. Planar fasciitis is a massage of the plantar fascia portion can be seen that the treatment effect, the arch support is to press the plantar fascia portion can see the effect of the massage when walking.

Referring to FIG. 4B, the body 211 is largely composed of a lower plate 211a, an absorption plate 211b, and an upper plate 211c.

First and second absorption layers 213 and 215 are formed in the absorption plate 211b, respectively, and first and second through holes 219a and 219b are formed in the upper plate 211c, respectively.

The lower plate 211a is formed such that a block hole L penetrates a portion corresponding to a lower side of the first absorbing layer 213. The block hole L is a portion through which the support block 230 to be described later passes.

A plurality of support blocks 230 are coupled to the lower plate 211a. The support block 230 is installed so that the tip thereof passes through the block hole L, and supports the absorbing plate 211b to form the arch support 217. That is, the arch support 217 is formed by adjusting the amount of protrusion of the plurality of support blocks 230. This is because the part corresponding to the human arch is different for each user, and the degree of the arch is formed, that is, the distance between the arch and the ground is different, so that it can be adjusted and used appropriately for each user.

The protruding degree of the support block 230 is used by cutting a portion to suit the user. In FIG. 4B, the portion represented by the dotted line in the support block 230 means a cut portion. Thus, the arch support 217 can be formed to be suitable for the user, so that the effect of the arch support 217 can be obtained more efficiently.

The most protruding position of the arch support 217 can be adjusted by changing the position of the longest support block 230 in the support block 230. In addition, in order to adjust the amount of protrusion can be easily to support a separate implant at the bottom of the support block 230.

When the user does not want to use the arch support 217 due to violent movement, the arch support 217 may be removed by simply removing the support block 230.
