Description

Insole of shoes

The present invention relates to a footwear insole capable of stably maintaining an arch structure of a foot by controlling the cushioning force of each part according to a landing state of the foot. More specifically, the cushioning force of each footwear is not changed suddenly, The present invention relates to an insole for a shoe.

A foot of a person is structured to mitigate an impact generated in walking or running by the shock absorbing mechanism of the inner arch of the foot when the weight is applied during walking or running. The foot maintains the shape of the arch by a wedge-shaped talus between the navicula and the calcaneus. Here, the talus serves as a key stone for supporting the arch, and a spring ligament is connected between the scaphoid and the calcaneus to support the arch. When weight is applied, the spring action of these arches absorbs the impact.

However, when a large load is applied to the foot for a long period of walking, traveling, or for other reasons, the arch of the foot partially or completely collapses, and the fatigue of the foot is further deteriorated. This situation often occurs in a flexible flat foot, and many of the causes result from a failure of the spring ligament function. When the arch collapses and the calcaneus is rotated, a large portion of the body weight is placed inside the big toe, which is an important cause of hallux valgus. In addition, stress on the plantar fascias due to excessive load is applied to cause plantar fasciitis. In addition, the center of gravity of the lower limb is changed to cause a strain on the knee, hip and waist, thereby increasing the possibility of degenerative changes in the waist and degenerative arthritis of the hip, knee, and ankle joints.

Conventionally, insole for shoes or shoes having various structures has been provided to solve such a problem. However, in most cases, the support of only one side of the arch during long walking or running is limited to providing a supporting effect by sliding the support on the support, and rather, the foot is pressed by the support to increase fatigue, . In addition, there was a product that elevated the height of the insole supporting the calcaneus to prevent external rotation of the calcaneus, but even in this case, the heel slip could not achieve the desired result.

In order to solve the above problems, the footwear insoles (Korean Patent No. 10-1230501), which can improve the stability of the feet and complement the arches of the foot, which are the shock absorbing mechanism of the foot, have been filed and registered by the present applicant.

The above-mentioned conventional insole for footwear absorbs impact when the load of the body is applied through the heel by walking or traveling, while the main pocket is squeezed, and the working fluid inside the main pocket is guided through the connecting tube, Thereby expanding the support pocket. Therefore, the fatigue of the body can be reduced by the shock-absorbing action even in the case of long walking or running. Further, when the support pocket is provided so as to be in contact with the arch portion of the foot or the outer surface of the heel, the arch can be collapsed or the heel can be prevented from slipping and rotating outwardly. Therefore, even when walking or running for a long time, the pain of the foot can be alleviated, and the abnormal deformity of the foot such as the hallux valgus can be suppressed. In addition, there is an advantage that a user having a flat foot can also provide an effect of relieving pain and maintaining an arch when walking.

However, in the conventional shoe insole, since the working fluid made of air or liquid is filled in the main pocket and the support pocket, the working fluid in the main pocket is moved to the support pocket as soon as the user presses the main pocket with the heel , The cushion function of the main pocket is deteriorated, and the support pocket is rapidly expanded, which may cause a burden on the user's foot or the support pocket may be damaged.

In addition, according to the physical characteristics of the user, the expansion rate of the support pockets should be adjusted according to the shape and structure of the user's foot. Since the expansion ratio of the main pockets and the support pockets of the conventional shoe insole is constant, There is a drawback.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a footwear insoles according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a shoe insole according to the present invention, FIG. 2 is an exploded perspective view of a shoe insole according to the present invention, FIGS. 3 and 4 are a plan view showing a use state of a shoe insole according to the present invention, Side view.

First, we briefly describe the structure of shoes and define terms. The shoe consists of a sole, which is the bottom part, and an upper part, which surrounds the foot. The sole is an outsole (out sole) which usually tough material is used to touch the ground and a midsole (mid sole) which is attached to the upper surface of the outsole to mitigate the impact, usually made of cushion material, And an insole (insole) which is provided on the upper surface of the midsole and is in contact with the sole of the foot. Here, the insole is detachably provided for cleaning or replacement, and various insole is selectively used according to the needs of the user. For example, an insole may be provided for good ventilation or for a key lift effect.

The insole for footwear according to the present invention is mounted on a midsole of a shoe 10 to directly support a sole of a user and includes an insole main body 100 in contact with a sole of a user, A main pocket 200 provided at a portion corresponding to the user's heel and filled with a hydrogel to allow contraction and expansion, and an arched portion between the scaphoid bone and the calamus of the user's foot on the bottom surface of the insole body 100 A first support pocket 300 installed at a site where the first connection tube 310 is connected to the main pocket 200 and communicated with the interior of the main pocket 200 through a first connection tube 310, A second support pocket 400 through which the main pocket 200 communicates with the main pocket 200 through a tube 410 and a second support pocket 400 communicating with the main pocket 200 and the first support pocket 300, And a base window 500 coupled to the bottom surface It is open configuration. At this time, the base window 500 is formed with a through hole 510 having a seating pawl 512 at a position where the main pocket 200 is seated, and the first supporting pocket 300 and the second supporting pocket The first seating groove 520 and the second seating groove 530 are formed at the positions where the first and second seating members 400 and 400 are seated. The description is omitted.

4, when the insole body 100, the main pocket 200, the first support pocket 300, the second support pocket 400, and the base window 500 are seated in the shoe 10 When the user presses the main pocket 200 with the heel, the main pocket 200 is flatly compressed and the hydrogel filled therein flows through the first connection tube 310 and the second connection tube 410, And is introduced into the support pocket 300 and the second support pocket 400. The first support pocket 300 and the second support pocket 400 expanded due to the introduction of the hydrogel physically restrain the foot from being deformed abnormally by pressing a specific portion of the foot. That is, the first support pockets 300 support arches made by the scapholum 1, the calamus 3 and the talus 5, and the second support pockets support the outer surface of the heel. At this time, the installation position of the first support pocket 300 and the second support pocket 400 can be changed according to a predetermined purpose, and the shape and number of the first support pocket 300 and the second support pocket 400 can be freely changed according to the user's selection.

In addition, when the external force applied to the main pocket 200 is released, the main pocket 200 is resiliently restored to its original state, and the main pocket 200 is provided with an elastic member such as a sponge do. Thus, if the heel of the user no longer presses the main pocket 200, the main pocket 200 is restored to its original state, and thus the first and second support pockets 300, The hydrogel returns to the main pocket 200.

As described above, the hydrogel inside the main pocket 200 flows into the first support pocket 300 and the second support pocket 400 while the user steps on the foot, The user's feet are prevented from being deformed by repeating the process of returning to the user's body 200. At this time, when the inside of the main pocket 200 is filled with air or fluid like a conventional insole for shoes, when the user steps on the heel of the main pocket 200, the first support pocket 300 and the second support pocket 400 When the first support pocket 300 and the second support pocket 400 are swollen rapidly, it is possible to inflict a strain on the user's feet. In addition, since the first support pocket 300 and the second support pocket 400 are inflated, There is a possibility that a problem may occur that the magnetic tape 400 is damaged. However, when the user pushes the main pocket 200 with the heel, the first supporting pocket 300 and the second supporting pocket 400 ) Has a characteristic of being slowly expanded, that is, a response speed is slowed down. Therefore, the shoe soles according to the present invention may cause the foot of the user to be uncomfortable due to the rapid expansion of the first support pocket 300 and the second support pocket 400, There is an advantage that the support pocket 400 is prevented from being broken.

At this time, the hydrogel can be changed into any kind of gel material if it has a certain level of viscosity. However, the hydrogel may be changed into any kind of gel, such as a hydrogel, so as not to be injured even if it comes into contact with the user's skin. It is preferable to select it as a harmless fluid material.

FIG. 5 is a plan view showing a coupling structure of the auxiliary chamber 600 included in the second embodiment of the footwear insoles according to the present invention, and FIGS. 6 and 7 are included in the second embodiment of the footwear insoles according to the present invention Sectional area of the chamber connecting tube 610 is changed by the operation of the regulating valve 612. Fig. 8 is a side view showing the use state of the second embodiment of the footwear insoles according to the present invention .

When the user presses the main pocket 200 with the heel, the first support pocket 300 and the second support pocket 400 are inflated. In accordance with the physical characteristics of the user, The expansion ratio of the first support pocket 300 and the second support pocket 400 should be set differently.

Therefore, the insole for shoes according to the present invention includes an auxiliary chamber 600 communicating with the inside of the main pocket 200 so that the user can freely adjust the inflation rate of the first support pocket 300 and the second support pocket 400, May be additionally provided. When the main chamber 200 is compressed, the hydrogel inside the main pocket 200 flows into the first and second support pockets 300 and 400 only when the auxiliary chamber 600 is further provided. The first supporting pocket 300 and the second supporting pocket 400 can be inflated to a low degree.

The auxiliary chamber 600 communicates with the main pocket 200 through the chamber connection tube 610 so that the amount of the hydrogel introduced into the auxiliary chamber 600 can be adjusted. The chamber connection tube 610 may be provided with a control valve 612 for increasing or decreasing the flow path cross-sectional area of the chamber connection tube 610.

For example, the chamber connection tube 610 has a flexible tubular structure with a thread formed on the outer circumference thereof, one outer side in the longitudinal direction of the chamber connection tube 610 is formed to have a larger outer diameter than the other side in the longitudinal direction of the chamber connection tube 610, And a nut structure that is screwed so as to surround the outer circumferential surface. 6, when the control valve 612 is screwed to the outer circumferential surface of the chamber connection tube 610, the control valve 612 moves in the longitudinal direction of the chamber connection tube 610 according to the rotation direction, The hydrogel inside the main pocket 200 is supplied to the auxiliary chamber 600 through the chamber connecting tube 610 while the chamber connection tube 610 is maintained in a wide channel state. A small amount of inflow into the first and second support chambers, that is, the inflation rate of the first support chamber and the second support chamber is reduced. 7, when the control valve 612 is positioned at a portion having a large outer diameter among the chamber connection tubes 610, the flow path of the chamber connection tube 610 is narrowed, so that the hydrogel inside the main pocket 200 The inflow of the first support chamber and the second support chamber into the first support chamber and the second support chamber is reduced.

The control valve 612 for controlling the flow path cross-sectional area of the chamber connection tube 610 is not limited to the structure shown in the present embodiment, and may be any structure Can also be substituted.

Meanwhile, when the auxiliary chamber 600 is in direct contact with the user's foot or on the bottom surface of the insole body 100, the user's foot may be unnecessarily pressed when the auxiliary chamber 600 is inflated. Therefore, when the auxiliary chamber 600 does not press the user's foot, the auxiliary chamber 600 may be installed in the sole 12 as shown in FIG.

FIG. 9 is a plan view showing a coupling structure of the auxiliary chamber 600 included in the third embodiment of the footwear insoles according to the present invention. FIG. 10 is a plan view showing the sliding valve according to the third embodiment of the present invention, Sectional area of the communication passage 602 is changed by the operation of the communication passage 620 shown in Fig.

The auxiliary chamber 600 may be formed separately from the main pocket 200 as shown in FIG. 5, and then may be configured to communicate with the main pocket 200 through the chamber connection tube 610, And may be integrally coupled to one side of the main pocket 200 as shown in FIG. Even when the auxiliary chamber 600 is integrally coupled to the main pocket 200, the auxiliary chamber 600 and the main pocket 200 are connected to each other as shown in FIG. 10, (602).

At this time, a separate sliding valve 620 is provided at a point where the main pocket 200 and the auxiliary chamber 600 are connected to each other to adjust the opening ratio of the communication passage 602. The sliding valve 620 is reciprocated in a direction transverse to the communication path 602 between the auxiliary chamber 600 and the main pocket 200 so as to linearly reciprocate in the direction The opening ratio of the communication passage (602) is adjusted according to the direction in which the sliding valve (620) is moved by the user, which is provided inside the connection portion of the main pocket (200).

The sliding valve 620 is formed in a plate shape and includes a main pocket 200 and a handle 622 protruding out of the main chamber so that the user can hold the sliding valve 620 by hand. The shape and the mounting structure of the battery can be variously changed. However, the connecting portion between the main pocket 200 and the auxiliary chamber 600 should be configured such that the hydrogel does not flow out to the outside through the portion where the sliding valve 620 is installed.

If the footwear insole according to the present invention is used for a long period of time, the hydrogel may flow out to the outside or the volume of the hydrogel may be reduced. In this case, even if the main pocket 200 is normally compressed, The pockets 300 and the second support pockets 400 may not normally expand.

Therefore, a separate filling nozzle (not shown) for supplementing the hydrogel may be provided in the auxiliary chamber 600. It is preferable that the filling nozzle is freely opened and closed according to the user's choice.
