And before explaining the present invention, insoles, insoles, insoles are synonymous in the dictionary meaning, in the present specification, all kinds of insoles that are typically inserted into shoes for convenience of description, according to the present invention Inserted into the shoe is called an insole, and in the insole of the present invention, the sheet layer of the fiber material except for the hard member is collectively described as an insole, and in this regard, the right interpretation of the present invention should not be limited.

Hereinafter, a self-customized insole according to the present invention will be described with reference to the accompanying drawings.

First, as shown in Figures 2 to 4, the self-customized insole according to the present invention insole 10;

Is coupled to the bottom of the insole 10 is hard member 20 deformable according to the shape of the sole;

The hard member 20 has an heel portion 21 having a curved portion 21A to support the insole 10 in close contact with the left, right, and back sides of the heel,

The insole 10 comprises an arch portion 21 to closely support the arch of the sole.

The arch of the sole includes both an inner arch, which is located inward and opposite to the person's feet, and an outer arch, which is located outside and not facing.

And the insole 10 is cut to fit the size of the user's foot is attached to the hard member 20.

As shown in the lower cross-sectional view of FIG. 3, the insole 10 includes a mesh layer 11 in contact with a user's foot, a buffer sheet layer 12, and an ethylene vinyl acetate (EVA) sheet layer 13. Are attached and formed.

The mesh layer 11 is made of a fiber material, such as insole of a conventional shoe commonly used.

And the mesh layer 11 may be made to have an effect that is excellent in removing the smell of the foot is added (사).

In addition, the buffer sheet layer 12 absorbs the impact to the sole using a normal ortho light material.

Here, OrthoLite is a material used in a well-known shoe insole for shock absorption, and is excellent in resilience and shock absorption with an open-cell sponge made in the United States, and is particularly effective in suppressing foot odor due to easy sweat discharge. Is applied to functional shoes such as hiking boots, running shoes, etc. It is a known technique having an improved shock absorption function than the insole made of simple fibers.

In addition, the EVA sheet layer 13 collectively refers to a resin obtained by synthesizing ethylene vinyl acetate resin, and includes fine pores to improve plasticity, stress cracking resistance, and impact resistance to absorb shock through the insole 10. To comfortably support the user's foot.

The EVA sheet layer 13 may be used, such as non-woven fabric, urethane, latex according to the manufacturer's choice.

In addition, the insole 10 has a plurality of vent holes 14 are formed on all or part of the insole 10 and the top or bottom or all of the insole 10 to absorb and discharge the user's sweat to comfort the inside of the shoe It is desirable to keep it in a state.

In the drawings of the present specification, since fine pores are formed in the mesh layer 11 of the fiber material and the buffer sheet layer 12 of the ortho light material, a plurality of vent holes 14 perforated only in the EVA sheet layer 13 are disposed on the bottom surface thereof. It can confirm that dog is provided.

Subsequently, the hard member 20 functions to support both the middle foot where the arches are formed and the rear foot including the heel.

To this end, the hard member 20 is preferably made of a high-strength thermoplastic resin or thermosetting resin or a synthetic resin thereof that is injection molded to a portion of the bottom surface of the insole 10.

As a material used for molding the hard member, an engineering plastic, and a resin in which a polyamide (PA) resin and nylon 66 are mixed is preferably used.

And the hard member 20, the insole 10 to support both the heel portion 21 for supporting the user's heel, the longitudinal inner arch formed in the user's both feet and the outer arch formed in the outer It comprises a tooth 22.

The arch portion 22 is configured to be inclined upward to support and fix both the inner and outer arches of the foot.

According to the structural characteristics of the foot, since the inner arch has a higher inclination angle than the outer arch, the arch portion also has a corresponding shape.

The heel portion 21 includes a curved portion 21A that is curved upward to support and fix both sides and the back of the heel of the user.

When the arch portion 22 naturally presses the mesh layer 11 inside the insole using the user's weight through the entire sole when the user wears the insole on the shoe,

The arch portion 22 is deformed to fit the shape of the user's foot, is made to be in close contact with the foot can be stably supporting the user's foot.

The curved portion 21A holds the insole 10 in the shape of an heel and at the same time ensures stable support of the heel through the strength of the hard member 20 to protect the heel from impact and minimizes the distortion of the foot inside the shoe during movement. It has a posture correction effect by inducing walking in the correct posture.

At the same time, the arch part 22 supports the arch of the user's foot to its original shape, and the inner and outer arches and the heel of both feet are distorted, and the weight dispersion effect is lowered. This can solve the problem of unstable posture distortion.

Particularly, the present invention is formed by integrally molding the heel portion 21 and the arch portion 22 of the hard member, the pressure transmitted to the forefoot with the big toe through the inner and outer arch from the heel when walking. This prevents abnormal twisting of the heel and arch.

Therefore, the present invention evenly distributes the user's weight to the entire sole of the foot through the hard member 20 in which the arch portion 22 and the heel portion 21 having the curved portion 21A are integrally formed. This three-sided contact structure prevents foot fatigue and joint strain when standing or moving for a long time by preventing deformation by the shoe.

And the present invention can implement the ergonomic design for the user's feet very easily can eliminate the cost and inconvenience for custom shoes.

Subsequently, in view of the above-described stable support of the user's foot and ease of manufacture, the hard member 20 is the arch part 22 and the heel part 21 are integrally formed with each other and are injection molded at once.

After the injection molding of the hard member 20, the arch portion 22 and the heel portion 21 is molded to be bent upwards while being coupled with the insole 10 through a press mold,

Alternatively, the arch member 22 and the curved portion 21A of the heel portion 21 are formed to be bent upward when the injection molding of the hard member 20 is performed on the bottom surface of the insole 10 through an adhesive process such as bonding. Can be combined.

At this time, the arch portion 22 and the heel portion 21 has a certain strength as a resin molding, so that when the upper end is in constant contact with the user's foot when pressed to cause pain or inconvenience when walking Can cause

The hard member 20 according to the present invention, in particular, by protecting the inner arch of the user's foot formed with a low inclination angle to give an excessive force to the arch to prevent the burden or pain caused by the outer end of the arch portion 22 It is characterized in that the incision line 22A is formed toward the inner front side.

The incision line 22A is formed by cutting a part of the main body of the hard member 20, and the arch part 22 constantly supports and supports the inner arch of the user's foot and at the same time, according to the shape change of the foot through the incision line when walking. As the teeth 22 are deformed, a stable arch can be supported while alleviating inconvenience of the user.

In addition, since the arch portion 22 of the hard member 20 is deformed according to the shape of the arch when the user walks through the incision line 22A, the pressure due to the deformation at the inner end of the incision line 22A increases when used for a long time. There is room for breakage due to the hard hard member (20).

Accordingly, the present invention forms a circular incision hole 22B larger than the width of the incision line 22A at the inner end of the incision line 22A, thereby relieving the pressure due to the displacement of the arch portion 22 while walking, and thus the hard member 20. ) Can be damaged.

Next, when walking, the user's heel has a relatively small change, and the insole 10 has a high possibility of causing pain due to constant contact, so the insole 10 has an upper end of the heel portion 21 of the hard member 20. Is formed extending upward from the heel pain caused by the rubbing of the hard member 20 is preferable.

When the extension part 15 of the insole 10 is formed, end portions of the hard member 20 and the insole 10 do not coincide with each other so that the user may be uncomfortable due to the step. Is attached to the insole 10 is recessed.

In addition, the extension portion 15 of the insole 10 may be formed not only over the heel portion 21 but also the entire hard member 20.

Subsequently, the self-customized insole according to the present invention may further include a buffer member 30 on the bottom surface of the heel portion 21.

The buffer member 30 may be made of a synthetic resin having an elastic force, such as non-woven fabric, urethane, latex, elastomer, etc. can solve the shock transmitted to the heel.

Although not shown in the drawings, the bottom surface of the hard member 20 includes a circular hole to which the shock absorbing member 30 is attached, and thus a part of the shock absorbing member 30 is attached to the hard member 20 in a recessed form. It is preferable to be.

And the present invention solves the impact transmitted to the soles through the insole 10 consisting of the buffer sheet layer 12 and the EVA sheet layer 13 stacked in two layers with the buffer member 30, the present invention sneakers As it can be used in a variety of footwear, such as shoes, hiking boots, the degree of shock absorption may vary depending on the type of footwear when the user runs.

Accordingly, the present invention can implement a double buffer function design in the shock absorbing member 30 to ensure the impact relief regardless of the type of shoes can increase the versatility of the insole.

In order to achieve the above object, the shock absorbing member 30 of the present invention is characterized in that the upper surface of the body 31 is formed like a dish as shown in FIG. 4. And the upper surface of the body 31 is formed with a plurality of engaging projections 32 protruding upward.

The coupling protrusion 32 is attached to the bottom surface of the hard member 20 to secure the coupling force of the buffer member 30 through the contact portion around the body 31 and the coupling protrusion.

In addition, the upper surface of the body 31, that is, the center portion is round and flat, but consists of a shape that is gently inclined toward the edge from the center portion. And the bar-shaped projection 33 is protruded radially upward in the center portion, the engaging projection 32 is protruded in the gently inclined portion.

Therefore, in the present invention, an air cushion layer 34 is formed between the hard member 20 and the buffer member 30 due to the dish-shaped buffer member 30 to primarily receive an impact transmitted from the heel portion 21. To solve.

In addition, when the impact is not canceled by the air cushion layer 34 according to the strength of the impact, the hard member 20 contacts the upper surface of the rod-shaped protrusion 33 and thereby relieves the impact by elasticity.

Since the shock absorbing member 30 by using the elasticity of the body 31 can be solved in the third.

The present invention introduces a shock-absorbing member 30 having a shock-absorption function of a multi-layered structure, and completely absorbs shock by performing shock absorption through the laminated structure of the insole 10, thereby completely protecting the user's soles and joints. It is possible to reduce the burden of purchasing expensive functional shoes by avoiding excessive pressure.

The lower surface of the buffer member is preferably provided with a fine hole 31A for air circulation of the air cushion layer 34.

In addition, the present invention, as shown in Figure 4, the cushioning member is provided with an elastic body 39 in the air cushion layer 34 to assist in the cushioning function while the original recovery of the air cushion layer 34 is made in a short time It is preferable that the shock absorber is absorbed even if the impact is generated continuously.

The elastic body may be formed of a coil spring coupled along the outer peripheral surface of the coupling protrusion.

Next, air shielding means provided in the buffer member will be described.

The shock absorbing member 30 of the present invention is bonded to the bottom of the heel portion 21 of the hard member 20 by bonding or the like. When used for a long time, the sealing force is reduced due to bonding, and air in the air cushion layer flows out through the gap. The buffer function may be degraded.

Accordingly, the present invention introduces an air shielding means provided on the coupling surface of the hard member 20 and the buffer member 30 to prevent the function of the air cushion layer 34 from deteriorating.

As shown in the lower enlarged cross-sectional view of FIG. 4, the air shielding means is formed on the lower surface of the heel portion 21 of the hard protrusion 20 and the shield protrusion 31B formed along the upper surface of the buffer member 30. The shielding groove portion 21B is formed to correspond to the shielding projection portion 31B.

First, the shielding groove 21B is recessed upwardly outward from the bottom of the hard member 20, and the shielding protrusion 31B is coupled to the shielding groove 21B.

The shielding projection 31B is formed of a flange 31Bb formed in an upward and outward direction along the upper surface of the body 31 of the buffer member 30 and a shielding blade 31Ba bent in a downward inward direction again at the end of the flange. An air barrier layer 31C is formed in an internal space between the flange 31Bb and the shielding blade 31Ba.

As the buffer member 30 is made of a material having an elastic force, as described above, the buffer member 30 is coupled by forcing the shielding projection 31B to the shielding groove 21B at the first coupling.

Since the shielding protrusion 31B is formed to conform to the shape of the shielding groove 21B of the air blocking layer 31C surrounding the air cushion layer 34, the air of the air cushion layer 34 is finely impacted. When trying to flow out between the buffer member 30 and the hard member 20 rather than the hole 31A,

The air cushion layer 34 is in close contact with the flange 31Bb and the shielding blade 31Ba to the inner surface of the shielding groove 21B while expanding in the outward direction by the pressure of the air from which the air blocking layer 31C flows out. By blocking the outflow of air can prevent the above-described buffer function is lowered.

In the above description of the present invention with reference to the accompanying drawings, a description of the self-customized insole having a specific shape and structure, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, such modifications, changes and substitutions It should be interpreted as falling within the protection scope of the present invention.
