Description

FUNCTIONAL SHOES INSOLE PROVIDING KINESIS TO METATARSALS}

The present invention relates to an insole to be worn on shoes, and more particularly, to increase the amount of muscle activity of the lower limbs associated with posture maintenance and gait, and to activate the intrinsic tolerance sensory organs to enhance the coordination of the human body and correct body shape. It relates to a functional shoe insole that can impart mobility to the midfoot to have an effect.

In recent years, as the quality of life of modern people improves and the social tendency that prioritizes health spreads, exercise equipment, programs, or various supplementary means that can improve the function of each part of the body or expect a certain therapeutic effect are being distributed. .

For example, in Europe and the United States, where research on sports science and rehabilitation medicine is active, products such as togu and sling have been developed and applied, through external receptors such as visual, auditory, and tactile sense as well as muscle strength. Improves sensory motor function to organize incoming sensory stimulation in the central nervous system and stimulates deep muscles (postural muscles) and joint protective muscles (stabilized muscles) that are difficult to access with normal movement. Or programs have been developed to improve dynamic stability.

In particular, since the foot of the body part is a means not only to support the weight of the person but also to allow the person to move by themselves, interest in the foot has recently increased. In line with this trend, a number of shoes, socks and shoe insoles having various functional or therapeutic effects have been introduced and are widely sold on the market.

As a functional product related to the foot, recently, an 'extension growth sneaker' was developed (Korea Republic Patent No. 10-2006-0067880), which provides an additional pad between the shoe insole and the midsole to provide a kicking effect. In addition, shoes that increase the concentration by generating a temperature difference between the big toe and the brain and brain when the mind and body are stabilized are being marketed.

Among them, the shoe insole is worn between the sole of the person and the shoe to absorb the shock transmitted to the foot during walking or stopping, and to support the position of the foot that may become unstable during exercise to allow the exercise in a stable state. In addition, by absorbing the sweat discharged through the skin such as the sole to prevent the slipping of the foot, and to facilitate the ventilation inside the shoe to play a role to make the inside of the shoe comfortable. In addition, it serves as a support frame so that the shoe shape can be supported, in this case it also serves to maintain the beauty of the shoe.

The development of technology to further improve these functions or to add new functions to the shoe insole is ongoing.

For example, Korean Patent Utility Model Publication No. 20-0398920 (registered on October 10, 2005) discloses a "functional shoe pad".

One side of the pad is installed between the upper cover and the lower cover is relatively thick between the control portion and the upper portion and the lower cover between the upper cover and the lower cover compared to the adjustment portion formed in the shoe or the inside of the shoe, etc. It is the technique regarding the functional shoe pad which made the part artificially high.

In this technique, one side of the pad may be artificially raised to expect the corrective effect of the leg bent by innate, malformed or habit. However, this technique can be used only to correct the legs bent by innate, malformed or habit, there is a problem that can not give a diet effect by giving exercise to the general people with normal leg form.

In addition, "Multifunctional Shoe Insole" is disclosed in Korean Utility Model Publication No. 20-0412025 (registered on March 15, 2006).

In the insole formed with a plurality of vents, the arch support window is divided into two vertically from the middle portion to the rear portion to support the arch of the foot, the arch support window is installed between the opening side of the arch support portion, and the arch support window The present invention relates to a multifunctional shoe insole comprising a cushion pad attached to a pad groove formed at a front part and a rear part, and a leather pad attached to an upper part of an arch support window to which a cushion pad is attached.

In the case of this technology, the insole placed on the upper part of the shoe can be expected to have the effect of ventilation, height, and exercise inside the shoe, and at the same time can realize the diet effect, while improving the fit by shock absorption and cushioning action. You can expect. In this technique, however, the spring is formed on the heel portion for the height-height effect, and the mobility is imparted. In particular, when walking or running fast, the ankle is exerted, and there is a problem that the risk of grounding the ankle is increased. Furthermore, long-term use of such insoles increases the likelihood of causing deformation in the wearer's walking and posture.

Therefore, in general, research results show that the exercise effect is greater and the additional body functions such as balance are improved when walking on unpaved roads or mountain roads, rather than paved roads in the city, and the anatomical structure of the foot and the biomechanical role of each part of the foot are applied. In addition to the shock-absorbing function, by providing a recoverable unstable state to the body to give the mobility of the various muscles connected to the foot by the development of the insole that can expect a diet effect is required.

Accordingly, an object of the present invention is to provide a shoe insole having a functional function that can increase the amount of activity of the muscle by giving motility to the muscles present in the foot and various muscles connected thereto, as well as enhance the coordination and body correction effect of the human body. have.

In order to achieve the above object of the present invention, the present invention includes a first pad portion located below the metatarsal bone to impart mobility to the midfoot portion during stop and walking; And a functional shoe insole capable of imparting mobility to the midfoot, wherein one side is connected to the first pad part and the other side is formed to the lower calcaneus so as to absorb a shock due to weight when stopping and walking. .

By using a functional shoe insole that can impart mobility to the midfoot according to the present invention, by stimulating the muscles and sensory nerves associated with gait and posture maintenance by imparting mobility to the soles, diet effect and coordination of the human body are enhanced and body shape. You can expect corrective effects. Accordingly, it is possible to increase the muscle activity of the lower extremities involved in walking, such as posture maintenance during walking and walking, and to strengthen the muscles, thereby improving the elasticity of the calf, thighs, and hips.

In addition, the musculoskeletal and nervous systems can maintain coordination in daily life, maintain the balance of the musculoskeletal system and the nervous system, and enhance organizing ability of these sensory stimuli to enhance sensory control regardless of age or gender. .

In addition, the functional shoe insole according to the present invention is applicable to all existing footwear, such as shoes and sneakers, except for slippers and high heels without the heel of the counter (counter) can be used in existing shoes There is an advantage.

In addition, the existing functional shoes are difficult to reflect the aesthetic taste of the consumer because the design of the product is not diverse, the functional shoe insole of the present invention can be applied to the shoes according to the taste of the consumer without design constraints. There is an advantage.

Furthermore, the functional insole of the present invention can effectively target the functional shoe market, thereby improving the national competitiveness of the domestic footwear and related subsidiary materials industries that are being pushed out of the global competition and becoming industrialized.

Hereinafter, with reference to the drawings will be described in detail a functional shoe insole that can impart mobility to the midfoot according to an embodiment of the present invention.

1 to 4, anatomically, the bones of the foot are composed of 52 pieces, each of which is 26 in one foot, and the 26 bones that constitute one foot include seven hindfoot or rearfoot, It is divided into five midfoot and 14 forefoot.

There are 19 muscles and guns on one foot, 38 muscles and guns on both feet, 18 of which are on the soles, and 13 lower extremities on the soles of the feet. In addition, the foot has 214 ligaments, each with 107 on one side. These ligaments join the foot joints, prevent unnecessary loosening of the joints, and provide structural stability to keep the foot functional from external shock. do.

Referring to FIG. 1, the rear end portion supports the most range of the weight at rest, and is the first contact portion with the ground during walking, and is responsible for shock absorption along with weight support. And the midfoot portion plays a role of maintaining the center of variance and weight of the calf with calcanus. In addition, the forefoot part plays a role of accelerating a moving speed when maintaining the center and walking together with the midfoot part.

FIG. 5 is a diagram illustrating a cycle of walking for explaining a functional shoe insole according to an embodiment of the present invention, and FIG. 6 illustrates a walking of a standing foot for explaining a functional shoe insole according to an embodiment of the present invention. One drawing.

Referring to FIGS. 5 and 6, the human gait may be classified into a stance phase in which the foot is in contact with the ground and a swing phase in which the foot is in the air when the foot is off the ground. In the walking cycle, the standing period accounts for 60% and the walking period accounts for 40%.

Positions can be further divided into heel strike, foot flat, mid stance, heel off, and toe off periods. The proportion accounts for 5%, 10%, 25%, 10%, and 10%, respectively, based on 60% of the standings.

The heel contact and the sole contact time is a time to maintain stability for shock absorption and weight shift, the present invention is shock absorbing and shock absorbing through the insole support and shock absorber located in the rear portion responsible for heel contact and foot contact Keep your feet stable.

In addition, the present invention is formed in the first pad portion, the second pad portion, and the insole support portion to form a curved portion to form a medial calf (longitudinal arch), verticular (navicular), first cuneiform (cuneiform) By supporting the first metatarsal line, it prevents over pronation when the sole touches the foot and distributes the impact.

The intermediate stand is responsible for maintaining the stability of the lower extremities and the upper body and progressing to a stable footing, and is a time to activate dozens of internal and external muscles in the sole of the foot to maintain stability. In the present invention, by creating an unstable environment at the midfoot, the activity time of various muscles associated with walking, such as the internal muscles and external muscles located on the sole of the foot, as well as the thigh, gluteal and erectile muscles, are extended, thereby increasing the amount of muscle activity and activity. Let's do it.

Due to the unstable environment formed in the middle foot, the human body unconsciously tries to integrate various information coming from the eye, the tactile sense, and the unique sensory sensory to maintain the balance of the body. This will be strengthened, improve the static / dynamic stability of the human body by activating the stimulation for the core muscles responsible for posture maintenance and joint protection muscles for stabilization.

The present invention is a method for creating an unstable environment in the metatarsal region, a plurality of metatarsal bones, muscles, tendons or ligaments connected to the foot according to the movement trajectory of the pressure transmitted to the foot by the weight received during walking And a pad formed at a position corresponding to the lower portion of the midfoot to allow the connecting portion) to act individually.

The heel lifting and toe pushing time is responsible for the movement and acceleration of weight, and the forefoot in charge of this may be inconvenient in use depending on the user when providing functionality as a very sensitive site. In addition, since the forefoot portion varies in width and height according to the structure of the shoe, the present invention does not form a separate pad or the like in the portion where the forefoot portion is located, or even if the above-described problem does not occur, for example, It is desirable to form a thin pad.

Hereinafter, a functional shoe insole capable of imparting mobility to the midfoot portion of the present invention will be described in detail for each component.

7 is a perspective view and a partially enlarged view for explaining the functional shoe insole that can impart mobility to the midfoot according to an embodiment of the present invention.

Referring to FIG. 7, the functional shoe insole may be applied to the right foot and includes a first pad part 100 and a second pad part 200. Functional shoe insole of the present invention that can be applied to the left foot of course has a form symmetrical to the shape shown in Figure 7 according to the left and right foot structure of the body.

The first pad part 100 serves to impart motility to the midfoot portion including the five metatarsal bones when stopping and walking. To this end, the first pad portion 100 is located below the midfoot portion, but preferably, the shape is formed to match the shape of the portion in contact with the metatarsal bone.

The first pad part 100 preferably uses a material having excellent elastic force in order to impart mobility to the midfoot portion. Specifically, Polyurethane (PU) or ethylene vinyl acetate (Ethylene Vinyl Acetate: EVA) may be used. Existing insole serves to maintain a stable posture by absorbing shock, but the insole according to the present invention has to give a constant repulsive force to the sole by the restoring force of the material when the wearer stepped on the ground, the elastic force And it is preferable to use the material excellent in a restoring force.

 To this end, specifically, the hardness (C TYPE) 25 to 35, tensile strength 10 to 20 kgf / cm2, tear strength 5 to 20 kgf / cm, elongation 300 to 450% and the resilience and elasticity of 1 to 7 mm thickness It is desirable to use resins such as this very good high density PU or EVA.

In another embodiment, the first pad part 100 may be formed to impart mobility to the midfoot portion, and to impart individual strength to the plurality of metatarsal bones (including a portion connected to the metatarsal bone). That is, since the foot has five metatarsal bones corresponding to each toe, the five metatarsal bones are all individually activated by different stimuli, or some metatarsal bones are tied to receive the same stimulus. Different densities of material may be used for each part.

Furthermore, the first pad part 100 has a first groove in the longitudinal direction of the shoe insole so that the plurality of metatarsal bones can be individually activated according to the movement trajectory of the pressure applied to the foot according to the weight received upon stopping and walking. It is preferable to form (110) further.

As the person stops and walks, the first pad part 100 receives a load due to the weight through the five metatarsal bones, and the first pad part 100 is individually based on the first groove 110 formed. Will move. The individual movements increase the amount of muscle activity of the lower limbs associated with posture maintenance and gait, and activate the intrinsic sensory organs to have coordination and body correction effects. You can also expect a diet effect.

The intrinsic sensory organs refer to sensory organs inside the body such as a sense of motion, parallel sense, internal organs, and the like, and are also called internal senses. The coordination refers to the ability to use the senses of various parts of the body to perform a given exercise task smoothly, quickly and accurately.

It is preferable that at least one first groove 110 formed on the first pad part 100 is formed, and the mobility of the plurality of metatarsal bones is adjusted according to the number of the first grooves 110. The intensity can be adjusted.

For example, when the first groove is formed, the first pad part 100 is divided into two parts, and the five metatarsal bones are largely subjected to stimulation due to elasticity of two different strengths. However, if four first grooves are formed such that each of the five metatarsal bones occupy one region, the first pad part 100 is divided into five parts, and all of the five metatarsal bones are stimulated with different strengths. Therefore, it becomes more likely to become a stronger unstable state than when forming one first groove.

As such, the reason for having different degrees of exercise intensity in each of the areas divided by the first grooves 110 is basically different in pressure applied to each metatarsal bone, and thus, the material constituting the first pad according to different pressures. This is because the elasticity is also changed according to. However, in addition to this, the elasticity of each region may be further increased by using materials having different densities in each of the regions divided by the first grooves 110.

According to the above principle, the intrinsic sensory organs will be activated so that the plurality of metatarsal bones in contact with the first pad part 100 can take a rest and walk posture in response to the deformation of the first pad part 100. Therefore, it can be expected to enhance the coordination of the human body and body shape correction effect, and even expect a diet effect.

In conclusion, the first groove 110 formed on the first pad part 100 may serve to individually impart mobility to five metatarsal bones, and further increase the number of the first grooves 110. In general, the motility imparted to the midfoot will increase.

In addition, the first pad part 100 further has at least one second groove 120 in a direction crossing the first groove 110 (a direction crossing the walking direction when the surface is a plane). It may include. The second groove 120 plays a role of preventing the foot from moving forward when walking.

That is, one or more first grooves 110 of the first pad part 100 may be formed on the first pad part 100 so as to impart mobility to the five metatarsal bones individually, or one or more agents The two grooves 120 may be formed. In addition, the first pad part 100 may form both the first groove 110 and the second groove 120 on the upper side.

On the other hand, since the first pad portion 100 can act when the sole is in contact with the inner bottom of the shoe, the sole part is not in contact with the inner bottom of the shoe in the form of a normal foot (not flat feet). The second pad part 200 to be described later is formed without being formed.

The second pad part 200 serves to absorb a shock due to body weight when stopping and walking. To this end, the second pad part 200 is preferably connected to the first pad part 100 to the calcaneus. In order to achieve this purpose, the second pad part 200 is preferably made of a material having good flexibility and excellent shock absorption, texture, heat insulation, and heat retention. In order to realize these characteristics, for example, the hardness (C TYPE) 10 to 52, tensile strength 25 to 35 kgf / cm2, tear strength 10 to 25 kgf / cm, elongation 300 to 450% and the thickness 7 to 15mm It is possible to use PU or EVA with good flexibility and excellent shock absorption.

The first pad portion 100 and the second pad portion 200 are connected to be formed in the lower calcaneus from the metatarsal bone of the foot, and preferably bent to conform to the shape of the sole. In addition, the first pad part 100 and the second pad part 200 which are connected to each other may allow the curved part 150 to be formed on the side surface to surround the outside of the calcaneus, the columnar bone, the first tongue bone, and the first metatarsal bone. Could be

The insole support 300 serves as a frame of a shoe insole. Accordingly, the insole support 300 serves to maintain the stability of the foot when walking. To this end, the insole support 300 is preferably formed below the first pad portion 100 and the second pad portion 200. More specifically, the insole support 300 may be positioned below the first pad part 100 and the second pad part 200 in a shape that surrounds the first pad part 100 and the second pad part 200.

The insole support part 300 is made of a material containing carbon, such as carbon fiber, which is light in weight and has a strong hardness for maintaining shape, as well as serving as a shoe insole, and maintains foot stability when walking. It is preferable to be.

In addition, the insole support 300 is preferably formed at least one deformation portion 310 to allow deformation by the load received when walking on one side. The insole support 300 is made of a rigid material that is relatively hard, but the foot is comfortable and stable when a certain deformation is allowed while walking or exercising. Therefore, it is preferable to form the deformation part 310 at a portion where distortion or deformation occurs most frequently and frequently, that is, at both ends of the width direction of the foot.

The position and number of the one or more deformation parts 310 will be determined according to the initial design purpose, and according to an embodiment of the present invention, the insole support part 300 may be formed of a portion of the first pad part 100. The second pad part 200 is designed to be formed adjacent to a portion where the first pad part 100 and the second pad part 200 are connected while being wrapped. In addition, the one or more deformable portions 310 may be formed in a hole shape to expose the first pad portion 100 or the second pad portion 200, or may be formed as a recessed groove.
