Description

Functional insole using elastic force

The present invention relates to a functional insole using an elastic force, the weight-bearing side of the foot touching portion protrudes downward to form a bent round shape to react the force of the foot of the wearer's body to move in the upper or front upper direction The present invention relates to a functional insole using an elastic force that provides upper or front upper mobility and prevents foot pressure.

Many modern people want to exercise regularly even in their busy lives. Nowadays, people often walk or run in comfortable sneakers with light sports clothes. At this time, the shoes placed at the bottom of the body to support the body and directly contact the ground play an important medium for moving the body.

The main functions of shoes can be divided into comfort and functionality suitable for sports activities.

General sneakers such as running shoes use a viscoelastic material as a midsole. In running, the force is transmitted to the body when the heel of the shoe touches the floor.

In walking, 1.2 times the power is transmitted to the body, and in running, the faster the speed, the more than 3-4 times the force is transmitted. At this time, when the heel touches the floor, deformation occurs at the bottom of the shoe. Deformation occurs when an external load is applied to the midsole and returns to its original form when the load is removed. The midsole causes energy loss along with the function of shock absorption during the load transfer.

If so, running shoes with too soft cushions will have a relatively high loss of energy. As the body moves, the energy transmitted to the shoe must be returned to the body as the body moves forward from the viscoelastic material in the midsole. This is called energy return. In the case of running with a constant load on the body, if the cushion is too good, you will feel tired easily due to high energy loss if you continue to exercise.

On the other hand, it can be seen that the midsole is harder in the case of marathon shoes than actually walking shoes. So far, it is known that the general impact force that occurs when the foot touches the ground is not closely related to joint injuries. Rather, studies have reported that a certain amount of continuous impact is effective in maintaining healthy bones.

In each sport, the role of shoes is important to make the best use of the body's functions. For example, a grass soccer field has cleats attached to the bottom of the shoe to prevent slipping and to handle the ball quickly and accurately. The number and height of cleats also vary depending on the weather conditions and the type of turf.

In addition, since the movement varies depending on the position of the football player, the shape of the cleat suitable for this is considered. In the case of major soccer shoes production, brand A and N, we develop soccer shoes for the best performance through the friction test using robots and the kinematic test for real soccer players.

High jumps are required to kick forward in athletics such as 100M sprinting or to intercept the ball in rebounds in basketball. Shoes should satisfy the characteristics of these events. However, the foot is a multi-segmental system consisting of several small bones that make it difficult to understand movement compared to other lower limb joints. It is known that energy is lost as the forefoot flexes around the metatarsophalangeal joint (MTP joint) of the foot. In order to minimize this energy loss, carbon fiber (carbon fiber) material was inserted under the insole in the form of a plate around sports brands of A company and applied to sprinting shoes and basketball shoes.

It can be seen that the loss of power is dramatically reduced in the case of hard carbon fiber midsoles that do not bend well compared to the use of ordinary midsoles when jumping in place. At 100m sprinting, a 2% improvement and a 2.5% (about 2cm) improvement in situ jump height were shown. If you understand the characteristics of the human body and develop a shoe like this, it will be able to perform its best function.

Recently, running shoes have been introduced to reduce excessive ankle pronation to control movement or to reduce the load on the knee joint. Despite these efforts, it is difficult to scientifically identify the effect of shoes. The reason for this is that shoe developers must understand the complex relationships with movement while taking into account the complex anatomical features of the human body. If you make good use of the dynamics of the human body, you will be able to create comfortable shoes that are comfortable and fit the functions required by sports.

In addition, there are no functional insoles for improving the recording of running, running in-place, and the like.

In walking, from the ankle to the foot, each type of movement appears in each walking cycle.

In general, the walking cycle of a normal person is as follows.

The initial fold is also called the Heel Contact Phase, which is the first step in the cycle of walking. It is the point where the base foot first touches the ground, and the heel contacts the ground first. At this time, the outside of the heel makes an angle to the ground, the foot is too unstable at that angle can not support the weight, muscles can not support the entire weight with the foot so tilted. So there are two possibilities that the foot can turn outward or inward, and the normal foot will turn inward until the foot is flat on the ground, which is pronation. If the foot turns out, it is called supination, and if the foot does not stop and keeps going out, that is, over-pronation occurs, ankle sprain occurs. In other words, the heel that comes in contact with the ground, which occurs after the heel folder, allows the foot to lie flat on the ground and support the entire weight.

The intermediate stance is also known as the foot flat phase, which is the next step after the initial ground, which is when the base foot rests horizontally on the ground and supports the load on the lower limbs. Revolutionary foot rotation helps to balance the body by allowing the foot to adapt directly to the ground, whatever the surface surface. In addition to the structure of the relaxed bone, the foot makes the impact better absorbed.

Heel Off Phase is the point at which the heel touches the ground. The foot must act as a lever to move the body forward, with the foot turning outwards, that is, by supination. This abduction allows the joints and bones to be firmly fixed, making the feet firm and ready for propulsion.

Propulsion (Toe Off Phase) is the last stage of the stance where the base is touching the ground, resulting in a foot clearance for smooth progression to the dilator. The knee joint flexes and the ankle joint Let's go. Toe lifting means that the toes push the ground and move forward.

Swing phase is a swing phase where the base is separated from the ground.

In other words, the walking cycle is followed by the heel folder, the sole folder, the heel lifter, the toe lifter, the stirrup, and then the heel folder. At the moment when the heel lift begins, the circumference occurs at the beginning of the heel lift, and the toe pushes the ground forward and moves forward.

Walking, running, etc. The biggest impact on athletic performance during long jumps is the heel lift with heel and the toe lift with toe.

1 to 2, the functional insole using the elastic force according to an embodiment of the present invention includes a fabric made of a fabric, a pad made of a foam having a cushion, a functional insole used to lay inside the shoe In the, including the heel support portion 100 and the paw support portion 300, the shape of the heel support portion 100 is deformed when the heel of the wearer treads the ground, when the heel of the wearer falls off the ground While the shape of the back foot support part 100 is restored, it is characterized in that it provides a reaction force to improve the upper movement force, the shape of the front foot support part 300 is deformed when the foot of the igniter treads the ground, While the shape of the forefoot support portion 300 is restored when the ball falls from the ground, it provides a reaction force to improve the upper or front upper movement force It shall be.

That is, the back heel support portion 100 provides a primary impact relief and reaction force by the principle of the dish spring, and the forefoot support portion 300 is also a structure that provides a secondary impact relief and reaction force by the principle of the dish spring.

The back foot support part 100 is provided below the surface corresponding to the heel of the functional insole body, and is formed in a round shape (bent in a cup shape) to correspond to the surface shape of the heel.

This is because the heel (heel cup) portion of the round shape design, to naturally transmit energy to the front of the foot due to the impact of the weight applied to the heel.

In other words, the heel (heel cup) portion of the round shape design, the heel folding machine, the foot folder, the heel lifter occurs in order to help the movement of the natural movement.

In other words, the heel (heel cup) portion of the round shape design, during the transition from the heel folding machine to the foot folding machine, the shape of the heel support portion 100, as in the principle of the spring plate is deformed, when the heel lifter The elasticity that the deformed shape is restored helps the heel to move upwards.

At this time, it is preferable that the material of the back foot support part 100 is made of a material having high rigidity so that buckling (buckling) does not occur due to the movement.

In this case, the hind foot support part 100 may have a hind foot reinforcement part 110 protruding in a shape corresponding to an edge of a part touching the ground when the heel of the wearer treads into the ground.

Back foot reinforcement 110 is to prevent the lateral deformation of the back foot support portion 100 in the course of the heel folding machine, the foot folding machine, the heel lifter, in order to form the back foot reinforcement 110, Forming the entire thickness of 100) can be reduced to reduce the manufacturing cost, so that the back foot support portion 100 can be bent smoothly to improve the impact absorption by the weight.

Here, the portion that is bent inward of the sole of the foot corresponding to the inside of the sole of the foot foot support part 100 is bent inward earlier than the portion that is bent inward of the sole of the foot corresponding to the outside of the foot of the foot foot support part 100. It may be characterized by losing (see FIG. 1).

This is to help the preparatory war proceed before the extraordinary war.

At this time, the inner side of the sole, the left edge of the right foot, the left edge of the right edge.

In addition, the outside of the sole refers to the right edge for the right foot and the left edge for the left foot.

In addition, the inside of the sole refers to the center of the sole.

As shown in Figure 3, the back foot support portion 100 of the functional insole using the elastic force according to an embodiment of the present invention may be characterized in that the thickness becomes thinner toward the outside in the center.

This is to prevent buckling (buckling) from occurring when the foot treads the ground.

In the example of FIG. 3, an example in which the thickness becomes thinner in appearance so that the thickness becomes thinner is visible. However, the present invention is not limited thereto, and the thickness is gradually thinned from the center to the outward direction.

Forefoot support portion 300 is provided on the lower side of the surface corresponding to the toe and foot ball of the functional insole body, is formed to include a portion to contact the toe and foot ball, it is bent so that the lower side of the portion corresponding to the foot ball side protrudes.

This is because the forefoot portion is designed to be bent to correspond to the shape of the foot ball portion, and is intended to naturally receive energy due to impact due to the weight applied to the heel to the front of the foot.

In other words, the front foot portion is bent in a protruding shape of the lower side, so that the movement of the foot that occurs in the order of the foot folders, heel lifters, toe lifters naturally proceeds.

In other words, the toe lifter flattens the shape of the forefoot support part 300 by weight when the sole is folded, and when the heel is lifted, the toe is lifted from the heel lifter by the elasticity in which the shape of the forefoot support part 300 is restored (bent). Helps to proceed with the machine, the shape of the bent forefoot support 300 is restored when the toe is lifted (unfolded) and improves the movement force to the upper or front upper part.

Forefoot support portion 300 is a protruding design, amplified the force to be pushed to the end of the toe by the bending force and stretched force received from the back foot support portion 100, as long as walking or ascent as a metatarsal joint (MTP) support role In mountain climbing, etc., energy loss can be prevented to reduce foot fatigue and improve endurance.

In addition, since the forefoot support part 300 is formed in a curved shape in accordance with the shape of the foot in the metatarsal joint region, it is possible to prevent energy loss and improve a jumping force, a speed, and the like.

In addition, the forefoot support portion 300 serves to balance the front and rear, left and right movement in the design of a gentle slope according to the shape of the foot.

In this case, the forefoot support 300 may have a forefoot reinforcement 310 protruding in a 'U' shape corresponding to the shape of the front and side outer sides of the foot support 300.

The forefoot reinforcement unit 310 increases the elastic force of the forefoot reinforcement unit 310 in the course of the foot folder, the heel lifter, and the toe lifter, and helps the direction of the force to move forward.

Due to this, it helps to move to the upper or front upper portion by the impact absorption and elastic force of the front part of the foot.

4 to 5, the functional insole using an elastic force according to an embodiment of the present invention is an intermediate foot support portion 200 formed to extend from the back support portion 100 to the germination (concave portion of the sole) side ) May be further included.

That is, the intermediate foot support part 200 extends from the rear foot support part 100 to the forefoot support part 300 side, and reinforces a portion corresponding to the arch of the sole of the foot so that energy can be delivered to the forefoot support part 300 side. to be.

This is to allow the foot cloud energy transmitted from the back foot support part 100 to the front foot support part 300 to be smooth and correct walking.

In other words, the heels, the soles of the feet, the feet, toes in order to carry the weight of the masai walking is naturally helped.

In addition, the intermediate foot support part 200 can protect the foot arch from shock absorption and foot arch by preventing shock and improving foot healing, such as flat foot, plantar fasciitis, and the like, and can also reduce foot fatigue.

In addition, the body shape and lower body skeleton, such as the limbs, can also be corrected and improved.

At this time, the middle foot support portion 200 is the medial arch support portion 210, a portion corresponding to the inner side of the sole of the foot protruding toward the toe side and the outer arch support portion, the portion corresponding to the outer side of the sole of the edge protruding toward the toe side. 220 may be included (see FIG. 5).

This reinforces the parts corresponding to the medial arch (inner arch) and the outer arch (outer arch) of the arch (part of the arch) to create a structure that can transmit energy to the forefoot support portion 300 side as much as possible, This is to reduce the production cost by using the minimum material.

As shown in Figure 6, the intermediate foot support portion 200 of the functional insole using an elastic force according to an embodiment of the present invention is the length (L1) of the protruding portion of the inner arch support 210 is the outer species It may be characterized in that it is shorter than the length (L2) of the protruding portion of the arch support 220.

This is to form a portion corresponding to the outer side of the sole of the middle foot support portion 200 longer than the portion corresponding to the inner side of the sole, to substantially reinforce the portion pressing the ground.

As shown in Figure 7, the intermediate foot support portion 200 of the functional insole using an elastic force according to an embodiment of the present invention is the width W1 of the protruding portion of the inner arch support 210 is the outer species It may be characterized in that it is longer than the width (W2) of the protruding portion of the arch support 220.

This is because the portion corresponding to the inner side of the sole of the middle foot support portion 200 is formed thicker than the portion corresponding to the outer side of the sole, so that the medial arch (inner calf) portion that should be substantially separated from the ground is separated from the ground. To help.

4 to 5, the back foot support portion 100 and the front foot support portion 300 of the functional insole using the elastic force according to an embodiment of the present invention is characterized in that the elastic modulus is formed of a material larger than the pad The rear foot support part 100 and the front foot support part 300 are separated from each other, and the rear foot support part 100 and the forefoot support part 300 are formed between the rear foot support part 100 and the forefoot support part 300. It may be characterized in that a section in which no material is used is formed.

Forming the material of the back foot support portion 100 and the forefoot support portion 300 with a material having a large elastic modulus (hard material),

Insoles with too soft cushions are designed to absorb shocks while minimizing energy losses, as they absorb shocks and cause energy losses.

In other words, the shape is deformed for shock absorption, so that the elasticity of the shape to help the movement.

However, using a minimum cushion pad to improve the wearing comfort, and having a back foot support portion 100 and the fore foot support portion 300 formed of a material (hard material) having a large modulus of elasticity on the bottom bottom side of the insole.

At this time, if the intermediate supporting portion 200 is formed, it is preferable that the intermediate supporting portion 200 is also formed of a material having a high elastic modulus (hard material).

However, when the back foot support part 100 to the front foot support part 300 are all formed of a material having a high modulus of elasticity (hard material), the movement from the foot folder to the heel lifter becomes unnatural, rather, it impedes movement. Can be.

Therefore, between the back foot support part 100 and the fore foot support part 300, a section (a section in which the fabric and the pad are mainly formed) where a material having a high elastic modulus (hard material) is not used is formed.

The material used for the back foot support part 100 and the forefoot support part 300 may use a nylon material having elasticity, and may use Polymide6.

As shown in Figure 8, the functional insole using the elastic force according to an embodiment of the present invention may be characterized in that the intaglio, embossed or intaglio and embossed in the shape of a predetermined pattern formed on the bottom.

Even if you place a perfect insole inside the shoe, you can create friction between the shoe and the insole during exercise. To prevent this, shoes and insoles are often glued together.

However, since the functional insole according to an embodiment of the present invention can be worn inside the shoe only for the recording measurement, it is estimated that many people use the adhesive without the adhesive.

Therefore, it is preferable to prevent slipping of shoes and insoles, and for this purpose, it is preferable to form intaglio, emboss, or intaglio and embossed shapes of a predetermined pattern on the bottom surface of the functional insole according to one embodiment of the present invention.
