Description

{FUNCTIONAL INSOLE USING ELASTIC FORCE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a functional insole using an elastic force, wherein a portion of the foot which is in contact with the foot is formed into a rounded shape protruding downward and the body of the wearer is subjected to reaction force The present invention relates to a functional insole using an elastic force which improves an upper or forward upward movement force and prevents a foot from being overloaded.

There will be many modern people who want to exercise regularly in busy everyday life. Nowadays, people often wear a light sportswear in the park and walk or run in comfortable sneakers. At this time, the bottom of the body to support the body and directly touch the ground shoes to play an important role in moving the body.

 The main functions of the shoe can be classified into comfortable comfort and functionality suitable for sports activities.

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

In walking, a force of 1.2 times the body weight is transmitted to the body, and as the speed increases, the force is transmitted 3-4 times more. When the heel touches the floor, deformation occurs at the bottom of the shoe. Deformation occurs when an external load is applied to the middle, and when the load is removed, it returns to its original shape. In the middle, energy loss occurs together with the function of shock absorption during load transfer.

For a running shoe with too soft cushion, this energy loss would be relatively high. As the body moves, energy transferred to the shoe must be returned to the body when the body moves forward in the viscoelastic material of the midsole, which is called energy return. If the cushion is too good for running with constant load on the body, if you continue exercising, you will feel fatigue easily because of the high energy loss.

On the other hand, in the case of the marathonization, it can be seen that the middle is harder than the walking. It has been reported that the general impact force caused by the contact of the foot to the ground in running is not closely related to the joint injury, but rather, some sustained impacts are reported to be effective in maintaining healthy bones.

The role of shoes is important to make the best use of body functions in sports events. For example, in a grass soccer field, a cleat is attached to the bottom of the soccer shoe to prevent slippage and to handle the ball quickly and accurately. The number and height of the cleats differ depending on the weather conditions and the type of grass.

Also, since the movement varies according to the position of the soccer player, the shape of the cleat suitable for this is considered. In the case of major soccer shoes production A and N brands, we develop a soccer shoe to show the best performance by using a robot for a new soccer cleat design and a kinematic experiment for actual soccer players.

A high jump is required to kick the ball forward in athletic events, such as 100M sprinting, or to intercept the ball in a rebound in a basketball game. Shoes should satisfy the characteristics of these items. However, the foot is a multi-segmented system composed of several small bones, which makes it difficult to understand movements compared to other joints. It is known that the energy is lost as the whole body flexion around the metatarsophalangeal joint (MTP joint) mechanically. In order to minimize the loss of energy, the carbon fiber material was inserted under the insole in the form of a plate around the sports brand of the company A and applied to the shoes and the basketball shoes for the sprinting.

It can be seen that the loss of power is sharply reduced in the case of a hard carbon fiber core which does not bend well when compared to a case where a normal midsole is used for a straight jump. In the case of 100m sprinting, the improvement of the function of 2% and 2.5% (about 2cm) at the jumping height was shown. If you understand the characteristics of the human body and develop shoes, you will be able to perform the best function.

In recent years, there have been introduced running shoes that reduce the pronation of excessive ankles to control movement, or cause less joint load on the knee joints. Despite these efforts, it is not easy to scientifically identify the effects of shoes. This is because shoe developers need to understand the complex anatomy of the human body, but also to understand the complex associations with motion. If you take advantage of the mechanical characteristics of your body, you will be able to make good shoes that are comfortable and fit the functions required by the sport.

Also, there are no functional insoles for improving records such as running and standing long jump.

In walking, each type of movement appears from our ankles to our feet at every gait cycle.

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

The initial folding device is also called a heel contact phase, which is the first step in the gait cycle, when the foot of the reference foot first touches the ground, and the heel touches the ground first. At this time, the angle from the outside of the heel touches the ground, and the foot is too unstable at that angle to support the weight, and the muscles can not support the entire weight with the feet tilted at that angle. So there are two possibilities for the foot to go outward or backward: the normal foot goes inward until it is flat on the ground, which is the pronation. If the foot goes out, it is called supination, and if the foot does not stop and continues to go out, then over-pronation occurs, resulting in an ankle sprain in the flat feet. In other words, the pivoting of the heel to the ground, ie the pivoting after the heel folding, allows the feet to lie flat on the ground and to support the entire body weight.

The mid-stance is also called foot flat phase. It refers to the period after the initial folding and the next step, when the foot of the reference foot is supported horizontally on the ground while supporting the load on the foot. The foot counseling helps balance your body by allowing your feet to adapt immediately to the ground, whatever the surface of the ground. In addition to the structure of the relaxed bones, the foot absorbs the shocks better.

The Heel Off Phase refers to the time when the heel, which was touching the ground, was heard on the ground. The foot must act as a leverage to move the body forward, by acting as a leverage by turning the foot outward, ie by supination. This swallowing allows the joints and bones to be firmly fixed, making their feet firm and ready for propulsion.

The propulsion (Toe Off Phase) is the last stage of the stance phase where the reference foot is in contact with the ground. Foot clearance occurs for smooth advancement. The knee joint is bent and the ankle joint I will. The toe lifter means that the toe pushes the ground and moves forward.

The swing phase is a period in which the base of the foot is separated from the ground while exercising the swing phase.

In other words, the walking cycle is carried out in the order of the heel folding device, the sole folding device, the heel lifting device, the toe lifter, the swinging device, and the heel folding device in the order of the heel folding. At the moment the heel lifting is started, the abduction occurs, and the toe pushes the ground at the toe lifter and moves forward, and our feet repeat this action.

Walking Running The most significant influence on mobility during exercise, such as long jump, is the heel lifter and the toe lifter that can hear the heel.

As shown in FIGS. 1 and 2, the functional insole using an elastic force according to an embodiment of the present invention includes a fabric made of a fabric and a pad made of a foam having a cushion, and a functional insole Wherein the shape of the rear support part (100) is deformed when the heel of the easy wearer is tilted to the ground, and when the heel of the easy wearer falls off the ground, the rear support part (100) and the front foot support part The shape of the forefoot support portion 100 is restored and the reaction force is increased to improve the upward movement force. The shape of the forefoot support portion 300 is deformed when the footwear of the user fits on the ground, The shape of the forefoot support part 300 is restored when the ball is separated from the ground surface, and a reaction force is provided to improve the upward or upward movement force It shall be.

That is, in the rear support portion 100, the primary shock mitigation and reaction force are provided by the principle of the diaphragm spring, and the forefoot support portion 300 is also a structure that provides the secondary impact mitigation and reaction force by the principle of the diaphragm spring.

The rear foot support 100 is provided on the lower side of the surface corresponding to the heel of the functional insole body and is rounded (cup-shaped) so as to correspond to the surface shape of the heel.

This is because the heel (heel) part is designed as a round shape, and the energy due to the impact due to the weight applied to the heel is transmitted naturally to the foot.

In other words, the heel (heel) part is designed as a round shape, and the foot movement generated in the order of the heel folding device, the foot folding device, and the heel lifting device naturally helps to proceed.

In other words, the shape of the heel portion (heel cup) is designed to be a round shape, and the shape of the heel support portion 100 is deformed like the principle of the diaphragm spring while being switched from the heel folding portion to the foot folding portion. The deformed shape helps the heel to move upward by the restoring elasticity.

At this time, it is preferable that the material of the rear foot support portion 100 is designed to have a high rigidity so as to prevent buckling due to the movement.

At this time, the backrest supporting part 100 may be formed with a heel strengthening part 110 protruding in a shape corresponding to the edge of the area where the heel of the wearer touches the ground when the heel moves to the ground.

The rear foot reinforcing portion 110 is formed in the rear foot supporting portion 100 in order to prevent the rear foot supporting portion 100 from being deformed outward in the process of progressing in the order of the heel folding machine, the foot folding machine, and the heel lifting machine. 100 can be made thin so that the manufacturing cost can be reduced and the back support 100 can be more smoothly bent so that the shock absorbing ability due to the weight can be improved.

The portion of the foot corresponding to the inside of the sole of the back support part 100 bent toward the inside of the soles of the back support part 100 is bent inward before the part of the foot corresponding to the outside of the sole of the back support part 100 (See Fig. 1).

This is to help the adduction of the abduction to proceed before the abduction.

In this case, the inside of the sole refers to the left edge of the right foot, and the right edge of the left foot.

The outside of the sole refers to the right edge in the case of the right foot and the left edge in the case of the left foot.

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

As shown in FIG. 3, the rear support portion 100 of the functional insole using an elastic force according to an exemplary embodiment of the present invention may be characterized in that its thickness decreases from the center toward the outer side.

This is to prevent buckling when buckling on the ground.

In the example shown in FIG. 3, the thickness of the thin layer is reduced so that the thickness of the thin layer can be visually observed. However, the present invention is not limited thereto. It is preferable that the thickness gradually decreases from the center to the outer side.

The forefoot support part 300 is provided on the lower surface of the functional insole main body corresponding to the toes and footballs and is formed to include a part where the toe and the football come into contact with each other and is bent so as to protrude below the part corresponding to the football.

This is because the forefoot portion is bent in a shape corresponding to the shape of the football portion and the energy due to the impact due to the weight applied to the heel is transmitted naturally to the foot.

That is, the forefoot portion is designed to be bent in a shape protruding downward, and the foot motion generated in the order of the sole of the foot, the heel lifter, and the toe lifter is naturally assisted.

In other words, when the soles of the feet are folded, the shape of the front foot support portion 300 is flattened by the weight, and when the heel is lifted, the shape of the front foot support portion 300 is restored (bent) And when the toes are lifted, the shape of the bent fore and aft support part 300 is restored (stretched) to improve the movement force to the upper part or the forward part.

The forefoot support part 300 is a protruding type design and is bent by receiving energy from the back support part 100. It amplifies the pushing force to the tip of the toe by the expanding force and supports long walking or uphill , It is possible to prevent fatigue of the foot by preventing energy loss and improve the endurance in mountain travel.

In addition, since the forefoot supporter 300 is formed in a bent shape in accordance with the shape of the foot, the energy loss can be prevented, and the jump force, speed, and the like can be improved.

In addition, the front foot support unit 300 has a gentle slope design according to the shape of the foot, and serves to balance the front, back, and right and left movement.

At this time, the forefoot support part 300 may be formed with a forefoot reinforcing part 310 protruding in a U-shape corresponding to the shape of the front and the lateral outline of the foot support part 300.

The front foot reinforcing part 310 enhances the elasticity of the front foot reinforcing part 310 in the course of proceeding in the order of the foot folding device, the heel lifting device and the toe lifting device, and helps the direction of the force to be directed forward.

As a result, it helps to move to the upper part or the upper part by the shock absorption and elastic force of the forefoot part.

4 to 5, the functional insole using an elastic force according to an embodiment of the present invention includes a middle foot support portion 200 (see FIG. 4) extending from the back support portion 100 toward the foot arch (recessed portion of the sole) ).

That is, the middle foot support portion 200 extends from the rear foot support portion 100 toward the front foot support portion 300, and reinforces the portion corresponding to the nape of the sole (longitudinal arch), so that energy can be transmitted to the front foot support portion 300 side to be.

This is to allow the foot rolling energy transmitted from the rear foot support unit 100 to be naturally transmitted to the front foot support unit 300 so as to enable smooth and correct walking.

In other words, the heel, the sole, the football, and the toe are weighted in the order of walking, which helps the natural progress.

In addition, the mid-foot support unit 200 protects the impact absorbing and arches of the foot, thereby preventing foot diseases such as flat feet and plantar fasciitis caused by a long exercise or the like, improving the healing, and reducing fatigue of the foot.

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

At this time, the middle foot support portion 200 includes an inner longitudinal support portion 210 having a portion corresponding to the inside of the sole protruded toward the toe side, and an outer longitudinal support portion 210 having a portion corresponding to the outside of the sole of the edge, (See FIG. 5). ≪ RTI ID = 0.0 >

This structure reinforces a portion corresponding to the medial nerve spinal arch (medial spinal arch) and lateral medial spinal arch (lateral medial arch), thereby making the structure capable of transferring the energy as much as possible to the forefoot support portion 300 side. This is to minimize the production cost by using the minimum material.

6, the intermediate supporting portion 200 of the functional insole using the elastic force according to an embodiment of the present invention has a length L1 of the protruded portion of the inner longitudinal supporting portion 210, Is shorter than the length (L2) of the protruded portion of the grip portion (220).

This is because the portion corresponding to the outside of the sole of the middle foot support portion 200 is formed to be longer than the portion corresponding to the inside of the sole so as to reinforce the portion that presses the ground substantially.

7, the middle support portion 200 of the functional insole using elastic force according to an embodiment of the present invention is configured such that the width W1 of the protruded portion of the inner longitudinal support portion 210 is smaller than the width And the width W2 of the protruding portion of the stopper portion 220 is longer than the width W2 of the protruding portion.

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, and the portion of the medial nerve (medial longitudinal arch) It is to help you.

4 to 5, the rear support portion 100 and the front foot support portion 300 of the functional insole using an elastic force according to an embodiment of the present invention are formed of a material having a greater elastic modulus than the pad The rear support portion 100 and the front foot support portion 300 are separated from each other and the back support portion 100 and the front foot support portion 300 are formed between the rear support portion 100 and the front foot support portion 300 Is formed in a region where the material of the first layer is not used.

The rear foot support 100 and the front foot support 300 are made of a material having a high elastic modulus (rigid material)

In the case of an insole having an excessively soft cushion, the impact is absorbed while at the same time absorbing the impact, so that the impact can be absorbed but the energy loss can be minimized.

That is, the shape is deformed for shock absorption, but the restoring elasticity of the shape can help the movement.

However, in order to improve the fit feeling, the cushion pad is used for the minimum, and the back support portion 100 and the front foot support portion 300 are formed of a material having a high elastic modulus (rigid material) on the lower bottom side of the insole.

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

However, if the rear foot support 100 and the front foot support 300 are all made of a material having a high elastic modulus (rigid material), the movement from the sole to the heel lifter becomes unnatural, .

Therefore, a section (a section where the raw fabric and the pad are main parts) in which a material having a high elastic modulus (rigid material) is not used is formed between the rear foot support 100 and the front foot support 300.

The material used for the rear support part 100 and the front foot support part 300 may be an elastic nylon material, and Polymide 6 may be used.

As shown in FIG. 8, the functional insole using an elastic force according to an exemplary embodiment of the present invention may have a predetermined pattern of embossing, embossing, embossing or embossing on the bottom.

Even if you are wearing the right insole on the inside of the shoe, you may get some friction in your shoes and insole. To prevent this, shoes and insole are often attached with an adhesive.

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

Therefore, it is desirable that the shoe and the insole are not slipped. For this purpose, it is preferable to form a concave, convex or concave shape and a relief shape on the bottom surface of the functional insole according to an embodiment of the present invention.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
