Description

The present invention relates to an insole for footwear such as shoes and sandals, and relates to an insole provided with dents and protrusions so as to fit the thumb ball portion and the heel portion of the sole, which perform various functions during walking and exercise. is there.

There are known shoes and insoles that promote blood circulation by stimulating them in various ways, such as providing protrusions to act on the soles of the feet or embedding magnets.

People maintain their health by walking upright on two legs. The feet support the body in a small area while playing an important role in the foundation of the body. Therefore, patent insoles 1 and 2 are provided with convex portions on the insoles of shoes to fill and fit the arch, or provided concave portions to reduce the load on the foot and body at the thumb and heel. Etc. have been proposed.
However, convexity and concaveness alone are not sufficient to reduce the burden on the ankles and knees. Foot diseases such as O-leg and knee joint pain are not limited to elderly people. It is also increasing among young people. One of the factors is the load such as footwear and weight that are difficult to walk, but the first is that the tibia cannot be externally applied in the final extension area, which puts a burden on the knee joint. Therefore, it is necessary to assist with the end-of-extension movement, and the toes facing outward during walking should be turned inward once, and when the foot leaves the ground, it should return straight in the direction of travel. That is, when the weight is concentrated on the thumb ball that controls the direction of travel, the head wheel type installed on the thumb ball Create a mechanism that automatically directs the toes to the inside by the protrusions. This causes an end-extension movement in which the tibia is twisted outward. If there is a problem with the knee, when walking, the toes are kicked out with the thumb ball, making it difficult for one foot to step forward, causing phenomena such as muscle weakness and walking. The problem is that it is difficult to move the weight smoothly from the heel to the toes when walking or running with only convex or concave.

In the present invention, a recess is provided in the thumb ball portion of the sole of the foot, a spiral wheel-shaped protrusion that spreads radially is arranged in the recess, and the heel portion is also provided with a recess and protrusion to enhance stability, thereby distorting the foot. It is intended to eliminate the deviation that is the cause of the above and to provide a functional insole that supplements walking and exercise by the synergistic effect of stability.

As mentioned above, shoes and insoles with dents and protrusions that increase stability and motility in the thumb and heel parts of the sole are not known at present.

The present invention has been made in view of this point. The insole and heel of the sole of the foot are captured and stimulated to make the person aware of it, and the dents and protrusions of this part are used to stop or kick up during walking or exercise. Or, it is an attempt to propose an insole that facilitates a change of direction , improves motor function , builds muscles by walking (running) with less blurring, and prevents aging.

The footwear insole according to the present invention is configured as follows. Recesses 2 and 4 are provided at positions corresponding to the thumb ball portion and the heel portion in FIG. 1, protrusions 3 and 5 are provided in the recesses 2 and 4, and a convex shape is provided on the back portion at a position corresponding to the arch of the foot. The insole of the foot provided with the panel 11 of the above, and the protrusion 3 provided in the recess 2 is a protrusion corresponding to the thumb ball portion, and a plurality of protrusions 3 outward from the center 13 of the columnar portion in FIGS. It extends radially to the tip 14 of the columnar portion, and the protrusion 5 corresponding to the heel portion is formed in a substantially cannonball shape. The plurality of radial protrusions 3 are curved in the counterclockwise direction for the right foot and in the clockwise direction for the left foot in FIG. Then, a counter 9 matching the shape of the heel is provided at the rear end of the heel portion of the insole 1, a convex finger pillow portion 7 is provided at the front portion of the insole 1, and the finger pillow portion 7 to the above. It was formed so as to gradually reduce the thickness of the insole 1 up to the depression 2.

The insole of the present invention has the effect of making it easier to move the body by reducing the burden on the body during walking and exercising. When walking, step out from the heel and land, while lifting the heel, first move the weight from the outside (pinkie side) to the fingertip, kick up to the toe with the thumb ball, recoil and move the other raised foot forward Will be done. However, the thumb ball bulges round to absorb the impact, making it difficult to capture the center of gravity. It is important to put the center of gravity firmly on the thumb ball part in order to move while catching the ground without shaking. The dent corresponding to the thumb ball is the part of the thumb ball, which firmly grasps the body weight and serves as a force for the radial protrusion to push forward in the dent. Since these depressions and protrusions can move in any direction in a well-balanced manner, the direction can be changed freely. Since the insole firmly catches the thumb ball and heel, it is easy to stabilize while standing on one leg without wobbling .

The heel has high sole pressure and the entire weight is applied to the landed heel, and the burden extends from the ankle to the knee, hip joint, hip, neck, and overhead. Since the dent provided in the heel part can be fixed together with the insole so as to completely wrap the heel, it absorbs the heavy pressure and releases it to the ground, and the protrusion provided in the dent functions to disperse the burden on the bone. .. In addition, since the heel fits comfortably in the dent, the landing does not shake and the direction is fixed, the wobbling is suppressed, and the weight can be smoothly transferred to the outside of the sole (pinkie side), so that the burden on the ankle and knee can be reduced. The synergistic effect of the insole of the thumb and heel improves motor function.

It is a top view of the insole of this invention. It is sectional drawing which shows the structure when the insole is cut along the XX'line of FIG. It is sectional drawing which shows the structure when the insole is cut along the YY'line of FIG. It is an enlarged view for the left foot of the radial protrusion of the insole thumb ball part of this invention. It is an enlarged view for the right foot of the radial protrusion of the insole thumb ball part of this invention.

The insole 1 of the footwear of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view of the insole 1 for the right foot of the present invention, and is integrally molded from the fingertip side to the heel side. As the material of the insole 1, synthetic rubber, polyester, polyurethane, silicon resin, EVA resin, cork and the like are used, but the material is not particularly limited as long as it can be molded. The surface of the insole 1 may be covered with a member such as cloth, but if the material can be used as it is, it may be uncoated.

FIG. 2 is a cross-sectional arrow view showing the structure seen from the thumb side when the insole 1 is cut along the XX'line of FIG. The thickness of the insole 1 is changed depending on the part, and reference numeral 6 is the toe portion on which the fingertip rests, the thickness is about 3 to 4 mm, and the discard size of about 1 to 1.5 mm from the fingertip to the tip of the insole 1. Is provided. Reference numeral 7 is a finger pillow portion on which the base of the finger rests, and has a thickness of approximately 5 to 8 mm. Reference numeral 2 is a recess provided in the thumb ball portion, and the thickness of the bottom surface is approximately 3 to 3.5 mm. , The thumb ball comes into contact with the recess 2 and is fixed. It acts as a non-slip to prevent the feet from slipping forward when walking. Since the back surface of the bottom surface portion 8 is reinforced with a panel 11 molded from special synthetic rubber, the sole arch portion is lifted like a spring when walking, so that the structure is such that it does not get tired even when walking for a long time.

A counter 9 is erected on the heel of the insole 1 so as to hold the heel from the rear side, and the counter 9 covers the heel to prevent foot escape and shoe rubbing. The counter 9 is molded with a height of 5 to 7 mm and a thickness of approximately 2 to 4 mm.

FIG. 3 is a cross-sectional arrow view showing the structure seen from the little finger side when the inlay 1 is cut along the YY'line of FIG. 1, and the thickness of the portion in contact with the little finger portion is approximately 5 to 8 mm. By making the thickness of the little finger side thicker than that of the thumb ball side, the open knee can be easily closed, the O-leg can be prevented, and the O-leg can be expected to be improved. Further, by walking using the insole 1 every day, the walking is corrected so that the toes face straight, and the walking can be performed in the correct walking posture.

Next, the structure of the thumb ball portion and the heel portion of the insole 1 will be described in detail with reference to FIGS. 1 to 5. As the action of the inlay 1, by strengthening the locomotorium (muscles, joints, bones) and improving the motor function, daily life such as walking with one's feet, standing and sitting and climbing stairs can be freely performed. It is to cultivate the habit of doing what you can do naturally. The role of the thumb ball is to absorb impact, step on, catch the ground, balance, change direction, kick out, and so on. Therefore, it is important to put the center of gravity on the thumb ball part so that it can be carried stably by eliminating the wobbling of the front, back, left and right. Since the recess 2 firmly catches the thumb ball, stabilizes it, and adjusts the balance, it becomes easy to perform exercises such as standing on one leg, squatting, and changing direction.

The recess 2 has a substantially mortar-shaped shape, the diameter of the upper part is about 3.5 to 4.5 cm, and the deepest part in the center has a depth of about 5 to 6.5 mm, gradually increasing. It is connected to the top. The thickness of the recess 2 is approximately 3 to 3.5 mm, and the thickness gradually increases toward the upper part and is connected to the height of the finger pillow portion 7.

A protrusion 3 is arranged inside the recess 2, and the protrusion 3 has a columnar portion 13 arranged at the center of the recess 2, and a plurality of columnar portions 14 are provided in the vicinity of the circumference of the recess 2. The columnar portion 13 and the columnar portion 14 are connected by ribs 12 so as to be evenly arranged. The diameter of the central columnar portion 13 is approximately 4 to 6 mm, the diameter of the columnar portion 14 is approximately 3 to 5 mm, and the dimension from the center of the columnar portion 13 to the center of the columnar portion 14 is approximately 1-1. It is 5.5 cm. The height of the protrusion 3 is approximately 3 to 5 mm. In this embodiment, six ribs 12 and six cylindrical portions 14 are provided, but the number is not particularly limited to six. For example, it goes without saying that about 3 to 8 pieces may be used.

骨（下腿骨）が外向きにねじれる働きをすることで、衝撃を吸収し膝や骨・軟骨への負担が軽減される。Ｏ脚や変形性膝関節症の人は最終伸展域で脛骨を外施させることができないため、膝にダメージを与えている。本発明の中敷１の拇指球部分に配設した放射状の突起３は受動的にその動きをさせるように形成したものである。FIG. 4 is an enlarged view of the protrusion 3 arranged on the insole 1 for the left foot. The protrusion 3 is composed of a columnar portion 13, a rib 12, and a columnar portion 14, and six columnar portions 14 are arranged concentrically with the central columnar portion 13 and the columnar portion 13, and the columnar portion 13 and the cylindrical portion 13 are arranged. The columnar portion 14 is connected by six ribs 12. The rib 12 is curved in the clockwise direction. FIG. 5 is an enlarged view of the protrusion 3 arranged on the insole 1 for the right foot, and is composed of a columnar portion 13, a rib 12, and a columnar portion 14 as in the case of the left foot. It is curved in the counterclockwise direction. In this way, since the protrusions 3 are formed so as to flow inward (thumb side) on both sides, the toes should once face inward when walking.

By twisting the bone (lower leg bone) outward, it absorbs the impact and reduces the burden on the knee, bone and cartilage. People with O-legs and knee osteoarthritis are injured in the knee because the tibia cannot be externally applied in the final extension area. The radial protrusions 3 arranged on the thumb ball portion of the insole 1 of the present invention are formed so as to passively move the protrusions 3.

Reference numeral 4 is a recess arranged in the heel portion, which has a substantially circular shape, has a diameter of approximately 4 to 7 cm and a height of approximately 3 to 5 mm, and the recess 4 holds the heel completely. It can be stabilized, the system is set up immediately after landing, it suppresses wobbling, it can be smoothly linked to the arch when walking, and it has the effect of maintaining the vertical arch and preventing the heel from falling inside. Reference numeral 5 is a protrusion arranged in the central portion of the recess 4, having a diameter of about 6 to 10 mm and a height of about 3 to 5 mm, and has a substantially cannonball shape as a whole. The heel has the largest calcaneus among the bones that make up the foot, and serves to support the impact during weight and exercise, and the protrusion 5 functions to disperse the impact on the heel bone. .. Reference numeral 10 is a shock absorbing sheet arranged on the back surface of the insole 1, which is fixed on a concentric circle with the recess 4, uses a repulsive material , and has the same or slightly larger diameter as the recess 4. I'm making it. The shock absorbing sheet 10 has an effect of alleviating the impact received on the heel and reducing the burden on the ankle and knee. Reference numeral 11 is a convex panel fixed to the back surface of the insole 1 at a position corresponding to the arch of the foot. The plantar fasciitis, which connects the underside of the heel bone and the base of the toes (thumb ball), weakens the spring force due to lack of exercise, aging, and fatigue due to overuse, and can serve as an arch. If it disappears, walking and exercise will be hindered. Since the heel and thumb are unstable due to difficulty in walking or walking, the foot remaining on the ground cannot support the body when walking, and the other foot cannot be raised to move forward. .. The convex panel 11 supports a weakened arch. In order to take advantage of the spring of the arch, it is necessary to stabilize both the heel and the thumb ball, and to habitually acquire the basic walking using the entire sole and fingers (thumb ball). The insole 1 of the present invention is an auxiliary tool for realizing it, and by continuous use, the plantar muscle is naturally strengthened and conducted to strengthen the entire foot muscle, and the joints associated therewith are strengthened. Exercise equipment such as bones and bones will be nourished.
