CONSTITUTION: A footwear insole comprises a base plate(10) which is equipped with a metarsal bone supporting part supporting the metarsal bone of the human body, is integrally extended to the metarsal bone supporting part, and supports the edge portion of the metapodium of the human body; a forefoot supporting part(21) supporting the whole forefoot of the human body; a metatarsus supporting part(23) except for the metarsal bone supporting part; and an inner plate(20) equipped with a metapodium supporting part(22) supporting the metapodium center.

Description

Shoe insole {INSOLE OF FOOTWEAR}

The present invention relates to an insole that is inserted into the inner bottom of the shoe to the sole of the human body in contact with the sole of the foot to support the sole of the foot, and in particular, taking into account the pressure distribution in which the pressure of the human body acts differently depending on the position of the sole. It relates to a single layer insole in which the insole is made of a material of different hardness by location.

In general, insoles are provided in contact with the soles of the human body to support the load of the human body to have a buffering effect, and to protect the feet. Certain parts protrude so that In addition, since the material of the insole is manufactured integrally using elastic and restorable foaming resin such as urethane foam, the entire insole is made of one material.

However, when the sole is grounded when walking, the pressure corresponding to the load of the human body does not act uniformly on the entire surface of the sole. For example, excessive pressure is concentrated on the front heel and heel, which is the front part of the middle foot, while relatively low pressure is applied to the valley part of the middle foot.

Therefore, the insole made of a single material does not properly cope with different pressures for each position of the sole, so that it is not possible to adequately buffer the portion where the pressure is concentrated. .

As a conventional technique for solving this problem, Korean Utility Model Registration No. 20-0388223 discloses a foam insole in which the middle part of the insole is cut in the transverse direction, separated into two compartments, the front part and the rear part, and the hardness of the partitioned part is different. Is disclosed.

However, in view of the biomechanical point of view, these foam insoles are manufactured by simply changing the hardness of the material of the front and rear parts without considering the pressure distribution acting on the sole. In other words, in the case of the front part of the insole, the pressure of the part where the heel is in contact with the toe is different from each other, because it is made of the same material, it is difficult to see that the pressure distribution is made efficiently.

In addition, in the prior art, it was commercially available to add a piece of insole made of a material of low hardness to a specific portion of the upper surface of the basic insole that the pressure is large, but this is because the insoles with different hardness are double padded There is a heterogeneity due to the difference between the thickness of the padded part and the part that is not, and the wearing feeling is not good. Also, since the added part is attached with an adhesive, there are problems such as poor breathability and weakened adhesive strength of the attached part. .

In order to solve the above problems, the present inventors have completed the present invention by considering the pressure and shape changes of the foot appearing when walking in consideration of the biomechanical aspects related to the pressure acting by the load when the foot is grounded. In the case of foot grounding, according to the pressure distribution generated differently for each position, the material of different hardness is used for each position, but the insole is made of one layer, and the upper surface is shaped to correspond to the shape of the sole and the toe part By applying the insole of the present invention, the metatarsal bones and forefoot bones are shaped to provide an insole for a shoe to give a feeling of wearing like bare feet.

In order to achieve the above object, the present invention, insoles in contact with the soles of the forefoot (A), the middle foot (C) and the rear foot (B) of the human body seated in the shoe, a plurality of insoles having different hardness for each zone The material is made, each material is characterized in that a single layer formed by combining.

As a specific means for this, any one of the forefoot hole 11, the middle foot hole 13, the rear foot hole 12 is formed therein to correspond to any one of the respective groups (A) (B) (C). Inner including at least one of the base plate 10 and the forefoot support part 21, the middle foot support part 23, and the rear foot support part 22 inserted into any one of the holes 11, 12, and 13. It is made of a plate 20, characterized in that the hardness of the base plate 10 and the inner plate 20 is made of different materials.

In a more preferred embodiment, the present invention is a heel hole (22a) perforated in the rear support portion 22 of the inner plate 20, the first plate of a material different in hardness from the inner plate 20 in the heel hole ( 22b) is inserted.

In another preferred embodiment, the heel hole 23a is drilled in the middle foot support 23 of the inner plate 20, and the second plate 23b is made of a material having a different hardness from the inner plate 20 in the heel hole. Characterized in that inserted.

According to the present invention, since the insole is formed in the same shape as the sole shape of the human body, and the insole is formed of different hardness materials for each position according to the pressure distribution acting when the foot is grounded, the impact force of the portion where the pressure is concentrated It can be absorbed by the enemy, and at the same time, almost no change in shape occurs at the part where the pressure is hardly applied. Therefore, it is possible to improve the fitting force and to provide a feeling of wearing such as bare feet.

Moreover, instead of attaching and bonding materials of different hardness, the distribution of pressure is partitioned to produce materials with different hardness in the shape corresponding to each compartment, and then the materials are assembled into a form to fit each other. As it forms, there is no heterogeneous feeling compared to the padding, and it is advantageous to exclude the use of the adhesive, and there is an advantage of excellent air permeability to the gap between each material. Therefore, it is easy to dry the sweat and emits odors, etc., so that a comfortable feeling of wearing can be maintained.

Hereinafter, with reference to the insole of the accompanying drawings showing a preferred embodiment of the present invention will be described in detail.

1 is a view showing the pressure distribution acting on the sole when the foot ground, first to define the name of each part of the sole of the human body and the corresponding insole in order to help the understanding of the present invention.

As shown in FIG. 1, the sole is generally divided into a forefoot (A) including a toe, a hindfoot (B) including a heel, and a middle foot (C) located between the forefoot (A) and the foot (B). When the sole is grounded to the ground during walking or striking, the pressure due to the load is distributed differently for each position of the sole.

Of course, although there is a slight difference depending on the position of the gait, when looking at the pressure distribution in the general case, the first zone (1) where the relatively high pressure acts on the heel portion of the rear foot (B) and the front heel portion of the middle foot (C) And a second zone 2 in which pressure lower than the pressure of the first zone 1 acts on the periphery of the first zone 1, including a portion where the toe of the forefoot A is grounded. And the third zone (3) where the lowest pressure is applied to the remaining portions other than the first and second zones (1) and (2), including the arched portion of the midfoot (C). .

In consideration of such a biomechanical pressure distribution, the present invention is insole in contact with each foot of the forefoot (A), middle foot (C) and rear foot (B) of the human body and seated in the shoe, the insole has a different hardness for each zone It is made of a plurality of materials, each material is characterized in that one layer is formed when bonding, the specific configuration thereof is illustrated in Figures 2 to 4.

Figure 2 is an exploded perspective view of a shoe insole according to the present invention, Figure 3 is an assembled perspective view of a shoe insole according to the present invention, Figure 4 is a plan view of a shoe insole according to the present invention.

2 to 4, the insole of the present invention is provided with a base plate 10 having an outer shape of the sole of the foot, the inside of the base plate 10 forefoot hole 11, the midfoot hole 13 ), The rear foot hole 12 and the like are formed, and these holes 11, 12 and 13 are positions corresponding to the forefoot A, the middle foot C and the foot B of the sole, respectively. .

Of course, according to a deformable embodiment of the present invention, either one of the forefoot hole 11, the middle foot hole 13, and the rear foot hole 12, or two arbitrarily selected two, is not formed, and the base plate 10 itself. It can be formed integrally with. That is, only one of the forefoot hole 11, the middle foot hole 13, and the rear foot hole 12 may be formed or only two randomly selected two may be formed. Such modifications are also within the scope of the present invention.

The base plate 10 manufactured as described above may have a shape corresponding to that of the third zone 3 in which the pressure is relatively small as shown in FIG. 1, and in consideration of the lowest pressure, a material having a high hardness, that is, elasticity. It is manufactured from the least material. If the hardness of the base plate 10 is in the range of 65 to 80, preferably 68 to 76 based on the hardness of Asuka C type (ASKER C TYPE) is not limited to the material, ethylene vinyl acetate (EVA) as an example of the material : Ethylene-Vinyl Acetate (Bu) molded foam, polyurethane (PU: Polyurethane) molded foam.

On the other hand, when any one or more of the above-mentioned holes 11, 12, 13 are formed in the base plate 10, in the form corresponding to the formed holes 11, 12, 13, A molded inner plate 20 is provided. That is, the inner plate 20 fills any one of the holes 11, 12, and 13 so that the insole is assembled to form a single layer, and the forefoot support part 21 and the middle foot correspond to each hole. It may be one of the support 23 and the rear support 22.

As the inner plate 20 is located as shown in Figure 1 the pressure is relatively greater than the position of the base plate 10, the inner plate 20 is made of a material of different hardness when compared to the base plate 10, Preferably, the material is made of a material having a lower hardness than the base plate 10. If the hardness of the inner plate 20 is in the range of 25 to 40, preferably 28 to 36, based on the hardness of Asuka C type (ASKER C TYPE) is not limited to the material, ethylene vinyl acetate (EVA) as an example of the material : Ethylene-Vinyl Acetate (Bu) molded foam, polyurethane (PU: Polyurethane) molded foam.

As such, when the base plate 10 having a high hardness and the inner plate 20 having a relatively low hardness are combined with each other, an inner plate 20 of a soft material is applied to correspond to a portion where pressure is largely acted as a buffering effect. In addition to the effective, insole combined with the base plate 10 and the inner plate 20 forms a single layer, so there is no heterogeneity because the layer is not formed as compared to the padded, and the fitting feeling is also improved.

On the other hand, the inner hardness of the inner plate 20 may be located separately to the lower hardness material. That is, the heel hole 22a corresponding to the portion in contact with the heel of the rear plate support part 22 of the inner plate 20 is drilled, and the heel hole 22a is made of a material having a different hardness from the inner plate 20. The plate 22b may be inserted, and preferably, the hardness of the first plate 22b is lower than that of the inner plate 20.

In this case, since the heel portion has the largest pressure distribution (first zone), as shown in FIG. 1, the softest material is applied to the portion to be in contact with the heel. Since it forms a layer, there is no heterogeneity due to the thickness difference, and the fitting feeling is also improved.

In order to assemble the heel hole 23a in the position corresponding to the heel of the middle foot C in the middle foot support portion 23 of the inner plate 20, and to assemble the front heel hole 23a by this technical thought. The second plate 23b of a material having a different hardness from the inner plate 20 may be inserted. Preferably, the hardness of the second plate 23b is made of a material lower than the hardness of the inner plate 20.

Accordingly, as shown in FIG. 1, since the largest pressure is distributed (first zone) as in the heel portion as in the heel portion, when the material having the softest hardness is applied to the portion to contact the front heel, the insole is of course excellent in cushioning effect. Since it forms one layer, there is no heterogeneity and the fitting feeling is improved.

Since the first plate 22b and the second plate 23b are relatively softer than the base plate 10 or the inner plate 20, it is difficult to measure the ASCA C type hardness, so that the Shore (Shore) If the hardness is in the range of 60 to 72, preferably 62 to 70, the material is not limited. Examples of the material include an ethylene vinyl acetate (EVA) foam molded article and a polyurethane having breathability. (PU: Polyurethane) A foamed molded article may be mentioned.

As described above, the insole assembled with a material having a different hardness for each position, the front edge portion of the front, more specifically, the front edge portion of the base plate 10 is curved in a form corresponding to the protruding shape of the toe. Concave-convex surface 15 can be formed, in this case, the front portion of the insole is the same shape as the toe structure it is possible to further improve the fit and fit (see Figure 4).

In addition, the side of the portion corresponding to the middle foot (C) in the base plate 10, it can form a metatarsal bone support 16 which is raised upward in the arch corresponding to the bone formed in the middle foot (C) of the sole, In this case, since the relatively large metatarsal bone support part 16 supports the metatarsal bone part of the sole, the fitting feeling can be improved.

Similarly, the base plate 10 is upwardly corresponding to the bone formed in the forefoot A of the sole between the forefoot hole 11 and the midfoot hole 13, that is, the bone formed between the toe and the midfoot C. When the raised forefoot support part 17 is formed, since the bone of the forefoot A is supported by the forefoot support part 17 having a large hardness, the fitting feeling can be improved.

In addition, when the first and second plates 22b and 23b including the base plate 10 or the inner plate 20 are formed, perforations having small diameters are selectively drilled on the first and second plates in the vertical direction. If the air flows in the up and down direction of the insole to prevent sweating as well as to reduce the occurrence of odor.

5 is a partial cross-sectional view of a shoe insole according to the present invention.

As shown in FIG. 5, an insole consisting of a base plate 10 and an inner plate 20, or an insole formed with a base plate 10, an inner plate 20, and first and second plates 22b and 23b. It is necessary to ensure that they are not separated from each other, because materials with different hardness form a layer in assembly.

Therefore, the entire outer surface of the insole can be wrapped and fixed with the cover 30, the cover 30 is preferably made of a breathable fabric, the method of fusion bonding to the outer surface of the insole by thermal compression to exclude the use of adhesive It may be configured as. As a modified example of this, even if the cover 30 is fused only to the upper surface of the insole, the shape of the insole is maintained, it is also possible to fuse the cover 30 on the upper surface of the insole.

Figure 6 is an assembled perspective view of an insole for shoes according to another embodiment of the present invention, the present invention can be modified as follows.

Referring to FIG. 6, since the hardness of the first plate 22b and the second plate 23b is the smallest, the first plate 22b and the second plate 23b have the lowest hardness, compared to the inner plate 20 which is in contact with the first and second plates 22b and 23b. Relatively more compressed may result in heterogeneity at the interface of each plate.

Therefore, the height of the first and second plates 22b and 23b may be slightly higher than the inner plate 20 to protrude upward, thereby minimizing heterogeneity, and the height may be about 0.5 to 1.0 mm. More preferably, the protruding shapes of the first and second plates 22b and 23b have an arch shape in cross section, that is, the interface height is the same as that of the inner plate 20, and is formed to protrude upward gradually toward the inside. Can be further minimized.

On the other hand, as shown in FIG. 6, when the vent holes 16a and 17a are respectively formed in the metatarsal support part 16 and the forefoot support part 17 of the base plate 10, the raised part of the base plate 10 by walking. That is, when the metatarsal support part 16 and the forefoot support part 17 are compressed, the ventilation holes 16a and 17a play a pumping role by repeatedly compressing and restoring the air so that the air inside the shoe is circulated to improve breathability. .

Of course, the ventilation hole is not limited to being applied to a specific portion of the base plate 10, and the first and second plates 22b and 23b including the inner plate 20 are also provided with the ventilation holes in each plate. Can be formed. That is, vent holes may be formed in the entire area of the insole.

According to a modified embodiment of the present invention, as shown in FIG. 7, the base plate 10 includes a metatarsal support 16 supporting the bone of the metatarsal C, and extends from the metatarsal support 16 to the posterior foot B. It is formed to support the edge portion of the, the metatarsal support portion 16 and the edge portion of the extended rear foot portion is made integrally.

In addition, the inner plate 20 includes a forefoot support part 21 supporting the entire forefoot A, and is integrally extended from the forefoot support part 21 to exclude the metatarsal support part 16, and The base plate 10 and the inner plate further includes a rear support part 22 extending integrally from the middle foot support part 23 to the inside of the rim of the rear foot B to support the center of the foot foot B. The hardness of 20) is designed to be different from each other. Preferably, the hardness of the base plate 10 is greater than that of the inner plate 20, and each material and hardness may be selected from the types and hardness values of the materials. Can be.

Meanwhile, the heel hole 22a corresponding to the portion in contact with the heel is drilled at the rear support part 22 of the inner plate 20, and the heel hole 22a is made of a material having a different hardness from the inner plate 20. The plate 22b may be inserted, and preferably, the hardness of the first plate 22b is lower than that of the inner plate 20.

In addition, the middle plate support 23 of the inner plate 20 also drills the front heel hole 23a at a position corresponding to the front heel of the middle foot C, and the inner plate 20 to fill and assemble the front heel hole 23a. The second plate (23b) of a material different from the hardness can be inserted, preferably the hardness of the second plate (23b) is made of a material lower than the hardness of the inner plate 20, the first, second The material and hardness of the plate can be selected from the material and hardness values described above.
