Description

Insole for posture correction {INSOLE FOR POSTURE CORRECTION}

The present invention relates to an insole for posture correction.

Walking habits are made under the influence of body type, personality, lifestyle, and skeletal structure. Especially, walking habits made in childhood become unchangeable habits after adolescence.

Gait occurs as a repetitive, repetitive process of the lower extremities to move the body forward. In other words, gait refers to the movement of one lower extremity supporting the movement and the other lower extremity moving forward when the body moves forward. Until the gait cycle is performed repeatedly, the roles are switched by each lower extremity.

On the other hand, children's shoes are manufactured and sold separately for spring, autumn, summer, and winter. In the case of children, the foot size generally grows by about 5 mm every 6 months. Despite this, in the fall, the size of the feet increases and the situation arises that it is impossible to wear them.

Children often do not tell their parents even if the shoes they are wearing are too tight or too small because their feet have grown in size. In this way, when children's shoes do not fit the foot, the toes may be strained first, causing deformation or damage. You may also feel discomfort when walking, and your walking distance may not be normal.

In particular, as the above-described phenomenon continues, it acts as impact stress on the children's feet, and the accumulation of excessive stress causes foot damage. In this process, unbalanced posture habits are induced and body imbalances in which the body leans to one side may occur. An example of an imbalance in the body is scoliosis, in which the spine is twisted and bent sideways. In the case of scoliosis, if not treated before the age of 13, the probability of living with an incurable disease increases for life.

Moreover, when compared to adult shoes, most children's shoes are tailored to the length of the feet or parents' tastes rather than giving special structural changes, so they can be said to be miniature versions of adult shoes, and ergonomic functions necessary for growth are ignored.

Methods for correcting body imbalance are largely divided into a method using corrective surgery and a method using a corrective device. The method using orthodontic surgery is not preferred in terms of surgical side effects and cost, and the method using orthodontic instruments causes a lot of inconvenience in daily life due to wearing orthodontic instruments for a long time.

Accordingly, recently, research for using the insole as an orthodontic appliance has been actively conducted. However, most of the functional parts such as hardness of the insole and shock mitigation and absorption according to the insertion of structures are occupied, and studies for correcting the walking posture are still insufficient.

For example, the 'body orthodontic shoe insole (registration number: 10-2049077)' has a first point, which is the point at which the outside of the heel touches during normal walking, and a second point, which is an inside point at which the stepping pressure is moved from the hindfoot to the forefoot. By providing a bottom plate and an upper plate having an upwardly inclined surface that is installed on the upper surface of the bottom plate and installed in a layer corresponding to the metatarsal bone at an angle of 13 to 14° from the outside to the inside, the occurrence of imbalance in the body is prevented and imbalance of the body is provided. An insole to correct the phenomenon has been suggested.

However, there is still a problem that only the bottom plate and the top plate of different thicknesses are provided, and such a bottom plate and the top plate alone cannot guide the normal gait cycle of the foot. Therefore, there is an urgent need for a technology that can correct an abnormal gait into a normal gait while creating a gait habit with a normal gait cycle.

Registered in Korea Patent Publication No. 10-2049077, 2019.11.20.

The present invention was invented to solve the above problems, and it is a technical solution to provide an insole for posture correction that can not only correct abnormal gait to normal gait while preventing foot disease, but also induce correct growth make it a task

In order to solve the above technical problem, the present invention provides an insole, including a bottom layer, a top sheet layer attached to the bottom layer, and an air pocket cushion inserted between the bottom layer and the top sheet layer, wherein the air pocket cushion Silver, a heel portion supporting the inner side of the heel, an arch portion formed in a shape corresponding to the arch of the foot in front of the heel portion to support the arch, is formed between the heel portion and the arch portion and moves toward the front inner side of the heel portion Including a convexly curved connection passage, when the load on the inside of the heel is applied to the heel portion during walking and the weight is moved forward, the load applied to the heel portion is released while the arch portion is expanded to guide the foot outward Then, it provides a posture correction insole, characterized in that the walking posture is corrected by generating a driving force in the direction between the big toe and the index toe.

In the present invention, the insole, a triangular guide pattern is detachably installed on the bottom surface of the bottom layer, characterized in that the shape is designed to fit the wearer's foot.

In the present invention, the triangular guide pattern, in a position adjacent to the arch portion, one corner is characterized in that it is installed to protrude toward the inner direction of the bottom layer.

In the present invention, the triangular guide pattern is installed at a position corresponding to the front outer side of the arch, so that one corner protrudes toward the inner direction of the bottom layer, and the direction between the big toe and the index toe when walking. It is characterized by inducing propulsion.

In the present invention, the reinforcing member is formed at a predetermined height upward from the center edge of both sides of the bottom layer along the rear edge, so that the load does not deviate from the path to the outside of the center of gravity when walking.

According to the insole for posture correction of the present invention by means of a solution to the above problem, by correcting the joints of the feet of growing children and arranging the bones in the correct position to induce correct walking, there is an effect that can prevent deformation of the feet that appear in adulthood. .

In addition, the maximum impact is achieved by touching the heel at the start of walking, allowing the gait movement to start with eccentric contraction at the dorsal flexion of the ankle joint at the heel touch, and at the same time placing the heel, knee and hip joint in a straight line. By reducing absorption, it has the effect of reducing the load on the knee and hip joint.

In addition, overall stability of the foot is improved by structural design to induce weight shift from the outside of the foot to the inside of the foot in the mid-stance phase, and by allowing the first metatarsal bone and the fifth metatarsal bone to contact at the same time before entering the toe-off phase. It is effective in preventing sprained feet.

In addition, the center of gravity is moved between the big toe and the index toe in the toe-off, which is the last step of walking, so that the toe-off can be performed with the strongest possible force, thereby increasing energy efficiency for walking and preventing fatigue at the same time. .

In addition, since the insole according to the present invention can be inserted into various shoes or an insole that has expired can be worn by replacing it with a new insole, there is an effect that a walking posture correction function can be given to shoes that do not have a posture correction function.

Hereinafter, the present invention will be described in detail.

First, FIG. 1 is an exemplary diagram showing the types of gait cycles. Fig. 1 (a) shows the gait cycle of the foot in a normal gait state, and as shown in the arrow direction of A → B → C shown in Fig. 1 (a), the thumb from the heel through the outside of the sole of the foot and the forefoot to achieve a natural gait. Ideally, distribute your weight by turning three times in the direction between your toes and index toes. On the other hand, Fig. 1 (b) shows the gait cycle of the foot in the pronated state, and it can be seen that the pronated gait cycle appears in the collapsed state of the foot arch. In addition, Figure 1 (c) shows the gait cycle of the foot in the supination state, it can be confirmed that the supination gait cycle appears in the state that the arch is too high.

Abnormal gait as in Fig. 1(b) and Fig. 1(c) becomes a habit that cannot be changed once it is decided, and especially, the deformation of the foot in the child's body type begins with foot fatigue when the child becomes an adult in the future, plantar fasciitis or corns, Not only does it cause pain such as hallux valgus, but it can also cause pain in the knee joint or hip joint and functional scoliosis at the same time.

Accordingly, in the present invention, it is possible to correct abnormal gait to normal gait while preventing diseases such as scoliosis caused by incorrect gait of the foot, and to provide an insole capable of inducing correct growth.

In relation to this, Figure 2 is a perspective view of an insole according to the present invention, Figure 3 is an exploded perspective view of Figure 2, Figure 4 is a bottom view of Figure 2, Figure 5 is a side view of Figure 2 will be.

2 to 5 , the insole of the present invention includes a bottom layer 100 serving as a base material for the insole, a top sheet layer 200 attached to the bottom layer 100 , and a space between the bottom layer 100 and the top sheet layer 200 . It comprises an air pocket cushion 300 to be inserted.

2 to 5 , the front of the insole is flat, and the air pocket cushion 300 is inserted into the rear of the insole to form a three-dimensional feeling of bending. As a result, the pressure can be dispersed by expanding the contact area between the sole and the insole by pushing the arch to the outside through the air pocket cushion 300 that is expanded at the part of the foot arch that is expanded during walking.

The bottom layer 100 of the present invention constitutes the base material of the insole.

With respect to the thickness of the bottom layer 100, it is preferable that the inner thickness is relatively lower than the outer thickness. Since the thickness of the bottom layer 100 decreases from the outside to the inside, a load is applied to the inside of the heel during walking and pressurization occurs on the heel part 310 and then the weight can be shifted to the outside of the arch part 320 to move the big toe. Propulsion force generation is facilitated in the direction between and the index toe. In addition, when the inner thickness of the bottom layer 100 is relatively low during walking, the foot may be inclined, and the air pocket cushion 300 is inflated to push the foot outward. In some cases, the bottom layer 100 may be formed to have a thinner thickness from the rear end to the front end.

It is preferable that the reinforcing member 110 in the form of a wall is formed at a predetermined height upward from the center edge of the bottom layer 100 along the rear edge so that the load does not deviate from the path to the outside of the center of gravity when walking. This reinforcing member 110 prevents the foot from swaying the center of gravity to the inside, outside, or rear side of the insole, thereby preventing the ankle from collapsing.

The reinforcing member 110 is formed to protrude at a predetermined height upward from the inner edge of the bottom layer 100 to support the collapse of the arch, and the inner reinforcing member 110a is provided along the end edge of the inner reinforcing member 110a. The rear reinforcing member 110 protrudes to a height and supports the rear axle, and the rear reinforcing member 110 is formed to protrude at a certain height upward along the end edge of the rear reinforcing member 110 to support the outside of the foot and prevent twisting of the foot (110b) It may be formed including

At this time, it is preferable that the height of the inner reinforcing member 110a is formed to protrude relatively higher than the height of the outer reinforcing member 110b. By making the height of the inner reinforcing member 110a higher than the height of the outer reinforcing member 110b, the bone as a whole does not sink, thereby preventing the formation of flat feet.

And since a triangular guide pattern can be detachably installed on the bottom surface of the bottom layer 100, the shape can be designed to fit the wearer's foot with these plurality of triangular guide patterns. Attachment and detachment can be made using a detachable means such as an adhesive, Velcro and double-sided tape, and is not limited to the above-described detachable means, but a means capable of attaching or detaching the triangular guide pattern to the bottom of the bottom layer 100 . If so, it can be used in a variety of ways.

It is preferable to use a material that is relatively harder than the material of the bottom layer 100 for the triangular guide pattern, which is to prevent movement by fixing the positions of the triangular guide patterns attached to the bottom of the bottom layer 100 .

Since the plurality of triangular guide patterns can be used by variously adjusting the height or thickness according to the shape of the wearer's foot or arch, it is possible to control the supporting force that can support the arch on the bottom layer 100 .

In this way, according to the characteristics of the wearer's foot, the triangular guide pattern having various heights can be moved and attached on the bottom surface of the bottom layer 100, and since the triangular guide pattern can be moved finely according to the characteristics of the wearer's foot, the fit of the foot is improved. can be improved

For example, at a position adjacent to the arch portion 320 on the bottom surface of the bottom layer 100 , the first triangular guide pattern 120 and the second triangular guide pattern 130 having a shape in which one corner faces in the inner direction of the bottom layer 100 are formed. A protrusion may be formed.

The first triangular guide pattern 120 may consist of an area from the center of the arch portion 320 to the front of the arch portion 320 , and a first-first triangle forming the outer shape of the first triangular guide pattern 120 . The guide pattern 121 and the 1-1 triangular guide pattern 121 are divided by a dividing groove h in the interior of the first-two triangular guide pattern 121 and relatively smaller in size than the 1-1 triangular guide pattern 121 .

The second triangular guide pattern 130 is formed to protrude from the bottom surface of the bottom layer 100 to the outside of the rear of the first triangular guide pattern 120 , and a 2-1 triangular guide forming the outer shape of the second triangular guide pattern 130 . The pattern 131 and the 2-1-th triangular guide pattern 131 are divided by the dividing groove h recessed in the interior, and the 2-2-th pattern 131 is relatively smaller in size than the 2-1 triangular guide pattern 131 . It is composed of a triangular guide pattern 132 .

In addition, a third triangular guide pattern 140 having a shape in which one corner faces inward of the bottom layer 100 may protrude from the bottom surface of the bottom layer 100 to a position corresponding to the front outer side of the arch part 320 .

The third triangular guide pattern 140 includes a 3-1 triangular guide pattern 141 constituting the outer shape of the third triangular guide pattern 140 , and a division groove recessed in the 3-1 triangular guide pattern 141 . It is divided by (h) and consists of a 3-2 triangular guide pattern 142 that is relatively smaller in size than the 3-1 triangular guide pattern 141 . The third triangular guide pattern 140 is formed to protrude from the bottom surface of the bottom layer 100 at a position corresponding to the front outer side of the arch part 320, so that when walking, between the big toe and the index toe It helps to induce momentum in the direction.

The first triangular guide pattern 120 , the second triangular guide pattern 130 , and the third triangular guide pattern 140 are formed to protrude in the shape of a protrusion on the bottom surface of the bottom layer 100 , so that the weight of the foot moves through the arch portion 320 . In the direction between the first triangular guide pattern 120 and the second triangular guide pattern 130 adjacent to the arch portion 320 and the third triangular guide pattern 140 on the front outer side of the arch portion 320 when passing through By guiding the center of gravity through, you can eventually reach the center of gravity between your big toe and index toe.

In particular, looking at the enlarged portion of FIG. 4 , the thickness of the first triangular guide pattern 120 , the second triangular guide pattern 130 , and the third triangular guide pattern 140 increases from the outer side (A) to the inner side (A′). may be formed to be thin. If the first triangular guide pattern 120, the second triangular guide pattern 130, and the third triangular guide pattern 140 are formed to be thicker from the outside to the inside, the foot is displaced to the outside during walking, causing ankle sprains. throw it away

In addition, a plurality of pattern grooves 150 may be recessed in the front outer portion of the bottom surface of the bottom layer 100 , and these pattern grooves 150 add a design element while adding a design element to the bottom surface of the bottom layer 100 of the shoe upper. It may help to improve adhesion after being inserted inside.

The top sheet layer 200 of the present invention is configured to be in direct contact with the foot by being adhered or attached to the upper surface of the bottom layer 100 .

As a material capable of forming the topsheet layer 200, one or more kinds may be selected from the group consisting of leather, fabric, fiber paper, and nonwoven fabric. The top sheet layer 200 may be adhered to the bottom layer 100 using an adhesive means such as an adhesive.

The air pocket cushion 300 of the present invention includes a heel portion 310 supporting the inner side of the heel, an arch portion 320 formed in a shape corresponding to the arch of the foot in front of the heel portion 310 to support the arch, It is formed between the rear axle part 310 and the arch part 320 and is configured to include a connection passage part 330 that is convexly curved inwardly in front of the rear axle part 310 .
