Shoes having the sole controlling the trajectory of ground reaction force center by appropriate medio-lateral arrangement of sole hardness}

The present invention relates to a shoe sole, in particular, to reduce the fatigue of the foot caused by abnormal pedestrian skeletal alignment and incorrect walking motion and the group of the joint to divide the shoe sole into at least three parts according to the leg shape of the general pedestrian The present invention relates to a functional shoe equipped with a sole for adjusting the ground reaction center point movement trajectory using an array of internal and external hardness differences that vary the hardness of each part.

In skeletal alignment of the geno varum or X-genu knee, the internal and external balance of the load on the knee is broken, resulting in damage to the articular cartilage at the site of high load. Onset.

1 is a front view of the human lower limb alignment viewed from the front.

As shown in FIG. 1, if the lateral angle θ (5) between the anatomical axis 1 of the tibia and the anatomical axis 3 of the femur in the lower limb alignment is 180 ° or more, the o-shaped knee (genu) varum), it is determined as an x-shape knee (genu valgum) when it is 165 degrees or less. Even if you have a skeletal alignment of the genu varum or the genu valgum, if you adjust the load on the soles inward and outward, the load on the knee joint It can be balanced internally and externally to relieve and prevent pain from degenerative arthritis. In the case of growing children and adolescents, the growth plate of the epiphysis is balanced to alleviate the growth disorders of the musculoskeletal system and induces growth to the normal musculoskeletal system, and eventually plays the role of achieving the genetically innate potential growth maximum.

FIG. 2 is a plan view illustrating a toe out phenomenon in which the foot is rotated 7 ° outward with respect to the traveling direction during normal walking.

As shown in FIG. 2, in the normal case of the pedestrian posture, the foot center line 150 walks in a toe out position rotated by about 7 ° outward with respect to the traveling direction 155 on the sole 50. The range of the tow out, which is considered to be normal walking, is the case where the center of gravity line 150 is rotated outward by about 0 ° to about 10 ° with respect to the traveling direction. In other words, walking in this position increases the internal motion of the subtalar joint, and an unbalanced load acts on the knee, causing damage to the knee joint.

In general, walking with a leg that is not curved in or out is ideal. When the foot is viewed from the top during natural walking, the front part of the foot is rotated by 7 ° to the outside of the body to perform the rolling motion by contacting the ground, so the sole part of the sole surface 50 is the outer part of the heel. . Then, the ground reaction force (pressure) center point is moved to the inside of the sole surface 50, the ground reaction force (pressure) center point is moved along the foot center line 150.

3 is a plan view showing a path along which the ground reaction force (pressure) center point moves on the sole.

As shown in FIG. 3, the portion where the sole surface 50 first touches the ground is the heel central protrusion point based on the toe-out rotation center point 140 present in the range of 23 to 30% of the heel to the heel ( pternion) and the toe center line 150, which is the line connecting the center of the second toe, when it is rotated 7 ° inward, the intersection with the heel boundary. The ground force center of pressure on the heel starts to move in the toe direction as the sole area of the foot gradually increases with the ground. People with normal lower extremity skeletal alignment and gait motion have a ground reaction (pressure) between ± 3 ° about the line segment where the center of gravity line 150 is rotated 7 ° outward with respect to the direction of travel as shown in FIG. The movement trajectory of the center point appears.

The movement track 160 of the most ideal ground reaction (pressure) center point touches the floor from the outside of the heel and moves in a straight line in the middle of the sole 50, and then the ground center of the ground reaction (pressure) moves to the second toe portion in a curved line. do. However, few people walk this way, indicating the movement trajectory of the normal ground reaction (pressure) center point. Since most people's legs are curved in or out, and the toe-out angle is often out of the normal range, it exhibits a movement trajectory different from the movement trajectory 160 of the ideal ground reaction (pressure) center point. For people with genu varum-type legs, the movement trajectory of the ground reaction force (pressure) center point moves parallel to the outside in the normal range during walking, so that the ground reaction force (pressure) center point of the O-shape knee is The movement trajectory 170 of FIG. In addition, in the case of a leg with X-shape knee (genu valgum) type, the movement trajectory of the center of ground reaction force (pressure) during walking is moved parallel to the inside in the normal range, so the ground reaction force (pressure) of the X-shape knee The movement trajectory 180 of the center point is shown.

4 is an exemplary diagram of the movement trajectory and the pressure distribution of the ground reaction force (pressure) center point measured by a pressure distribution measuring device when walking barefoot. On the right side of the pressure distribution diagram of Figure 4 is a color-specific table according to the pressure is shown.

As shown in FIG. 4, a pressure distribution measuring device shows an example in which the pressure distribution on the sole surface and the movement trajectory of the ground reaction force (pressure) center point appearing when walking barefoot are measured. It is most preferable to measure or recommend a customized product for each individual's skeletal alignment and gait after measuring a walking characteristic of an individual in a shop or a hospital equipped with such a pressure distribution measuring instrument, but it is difficult to realize realistically.

5 is a plan view of a conventional shoe sole.

That is, as shown in Figure 5, the conventional shoe sole 10 is the movement trajectory of the ground reaction force (pressure) center point due to the individual walking movement without the function of adjusting the deviation from the normal according to the individual skeletal alignment It was designed and produced to reflect this. In some running and walking shoes, there is a product that provides the function of placing a hard material inside the heel so as to prevent excessive rolling of the inner part of the foot, but this reduces or slows down the amount of inner motion. It does not control the movement trajectory of the ground reaction force (pressure) center point. So far, no shoe has provided the ability to control the overall movement of the foot while it lands on the ground, such as the initial ground landing behavior of the foot, normal internal and external load distribution after landing, and ground motion of the foot.

Most pedestrian bridges are curved in or out. Therefore, the optimal position of the heel does not touch the ground for the first time when walking, but first touches various parts from the inside to the outside of the foot. In the middle and the front part of the foot, the movement trajectories of various types of ground reaction (pressure) center points are drawn according to the skeletal alignment form for each individual. As described above, when abnormal gait motions continue, children and adolescents in the growth phase do not grow normally, and skeletal alignment is not corrected, and thus normal growth is not reached. In addition, elderly people with weak joints or pedestrians with diseases such as arthritis and discs have difficulty in moving due to excessive strain on their joints and lower back, and difficulty in walking due to fatigue on their feet and legs, and deterioration of walking ability due to illness. Will suffer.

In order to solve the above problems, it is most desirable to correct the shape of the legs or to make and wear customized shoes for each individual, but it takes a lot of time to correct the wrong skeletal alignment, and the customized shoes are expensive to be popularized. There is difficulty. It is faster and easier to solve walking fatigue, musculoskeletal system, and growth disorder resulting from incorrect skeletal alignment and walking motion by adjusting the movement track of the wrong ground reaction (pressure) center point during walking.

On the other hand, the current pedestrians are wrong as described above because they are using the same type of shoe soles 10 made of a single type made of synthetic resin material instead of shoes that fit the individual leg shape, and also using synthetic resin material The movement trajectory of the ground reaction (pressure) center point cannot be controlled.

The present invention is to solve the above problems, by dividing the shoe sole into at least three parts to produce each hardness differently. The general population who completed growth reduces walking fatigue and musculoskeletal pain due to abnormal skeletal alignment and incorrect gait habits, and the growth and potential growth of normal musculoskeletal system by relieving the growth disorder of musculoskeletal system in the growing children and adolescents. Aim to induce maximum value.

As a means for achieving the above object,

A central portion of the shoe sole divided into at least three parts, the central portion divided along the length of the shoe; An inner support portion coupled to one side of the center portion and formed on the inner portion of the shoe sole; It is coupled to the other side of the center, and includes an outer support formed on the outer portion of the shoe sole, it is characterized by varying the hardness of each part.

In addition, those who have skeletal alignment of the lower leg of the O-shaped knee are characterized by manufacturing the hardness of the soles in the order of the hardness of the outer support part, the hardness of the inner part, and the hardness of the center part.

In addition, the person who has the lower extremity skeletal alignment of the X (X) -shaped knee is characterized in that the hardness of the sole is made in the order of the hardness of the inner support portion> the hardness of the outer support portion> the hardness of the center portion.

In addition, the inner support, the central portion and the outer support is characterized by using different materials to make the hardness of each part different.

In addition, the inner support portion, the center portion and the outer support portion is characterized by manufacturing the hardness of each part by varying the molding compression ratio during molding.

In addition, the inner support, the central portion and the outer support is characterized in that they are formed integrally or bonded to each other using an adhesive.

In addition, the shoe sole is divided into at least three parts in the longitudinal direction of the heel.

In addition, in the shoe sole of the shoe sole shape, the heel portion of the shoe sole is combined with the shock absorbing portion divided into three parts, characterized in that the hardness of the inner support and the center and the outer support of the shock absorbing portion is different.

In addition, the shoe sole is divided into three parts of the forefoot part, the midfoot part, and the rear end part with an oblique line directed from the outer part to the inner part part, and the middle foot part includes a central part; An inner support part coupled to an inner side of the central portion; It is characterized by varying the hardness of each part, including an outer support formed by being coupled to the outside of the central portion.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

As described above, according to the present invention, by controlling the movement trajectory of the wrong ground reaction (pressure) center point in the normal form, it is possible to minimize the crowd going to the joint and the waist due to the wrong walking motion, thereby protecting the human musculoskeletal system and reducing the pain of the joint. Minimize, and long walks lead to less foot and leg fatigue. In addition, in diabetic patients with poor blood circulation, foot care is important, and thus, foot fatigue can be prevented by preventing foot complications such as foot ulcers. In addition, elderly people with weak joints, or people with diseases such as rheumatism, discs can only walk walking shoes wearing the present invention to relieve the pain of the musculoskeletal system, protect the human musculoskeletal system and can walk normally. In addition, children and adolescents with skeletal alignment abnormalities and growth disorders due to improper walking movements can perform normal gait simply by walking in shoes that apply the present invention, thereby restoring normal skeletal alignment. It is possible to achieve growth and normal growth to the normal musculoskeletal system.

6 is a plan view of a shoe sole according to the first embodiment of the present invention.

As shown in Figure 6, the shoe sole 100 is divided into at least three parts of the horizontal length across the inner portion 20 in the outer portion 30 of the shoe sole to the central portion 120 and the inner support portion 110 and It consists of an outer support 130.

The central portion 120 is divided along the length of the shoe is formed in the center of the shoe sole.

The inner support 110 is coupled to one side of the central portion 120 is formed in the inner portion 20 of the shoe sole 100.

The outer support 130 is coupled to the other side of the central portion 120 is formed on the outer portion 30 of the shoe sole 100.

Referring to the use embodiment of the present invention below.

(First embodiment)

In the present invention, in the sole of the shoe 0% to 30% in the heel of the foot, 31% to 60% of the range is called the midfoot, 61% to 100% is called the forefoot. Also, in the lower extremity alignment, when the lateral angle between the anatomical axis of the tibia and the anatomical axis of the femur is 180 ° or more, it is a genu varum, and when it is less than 165 °, it is a genu valgum. Represented by

As shown in FIG. 6, the shoe sole 100 is manufactured by combining an inner support part 110 and an outer support part 130 on the other side of the center part with a central part 120 formed at the center.

FIG. 7 is a cross-sectional view of A-A shown in FIG. 6.

As shown in FIG. 7, the shoe sole 100 is made of a material having different hardness from the inner support part 110, the outer support part 130, and the central part 120 to be integrally combined in a mold or with an adhesive. Combine with each other. Each part is made of a material of different hardness, so that the movement trajectory 170 of the ground reaction force (pressure) center point of the O-shaped knee and the movement trajectory 180 of the ground reaction force (pressure) center point of the X (X) shape knee Adjust the movement trajectory 160 of the ground reaction force (pressure) center point is ideal for pedestrians showing. At this time, the material of each part is produced using any one of a sponge, rubber, synthetic resin, it may be used a material not mentioned in the present specification.

3 is a plan view schematically illustrating a path along which the ground reaction force (pressure) center point moves on the sole.

As shown in FIG. 3, those with normal skeletal alignment and gait motion have a movement trajectory 160 of an ideal ground reaction force (pressure) center point when walking, and the center of gravity line 150 moves outward with respect to the direction of body progression. The first ground landing point is not the center of the heel, but the toe out center of rotation (140) where the foot centerline is in the range of 23 to 30% of the heel to the foot, because the foot is walking with the toe out rotated by 7 °. It is the part that intersects the heel boundary when it is turned 7 ° inward. After the ground landing for the first time, the ground reaction force (pressure) center point approaches the foot center line 150 before reaching the center point of the heel and moves in a straight line to the point of 60% along the foot center line. Fold and move out. That is, the ground reaction force (pressure) center point is moved from the outside of the heel to the floor to the second toe part through the center of the sole 50. However, since most people's legs are curved in or out and do not have the correct walking behavior, they show a movement trajectory different from the movement trajectory 160 of the ideal ground reaction (pressure) center point.

For people with genu varum-type legs, the movement trajectory of the ground reaction force (pressure) center point moves parallel to the outside in the normal range during walking, so that the ground reaction force (pressure) center point of the O-shape knee is The movement trajectory 170 of FIG. In addition, in the case of a person with a leg of X-shape knee (genu valgum) type, the movement trajectory of the center of ground reaction force (pressure) is moved parallel to the inside in the normal range, so that the ground reaction (pressure) of the X-shape knee The movement trajectory 180 of the center point appears. The eight-step walking position is when the toe-out angle is larger than the normal range. When walking in this position, the outer lateral part of the heel farther than the normal ground contact first touches the ground. The movement trajectory of is bent toward the center line of the foot. This means that early internal exercise, which causes knee arthritis, occurs rapidly.

In order to reproduce the movement trajectory of the ground reaction force (pressure) center point when a person with a normal leg skeletal alignment pattern walks normally, the hardness of the sole is determined by the inner support part 110 = the outer support part 130> the center part 120. Produce and wear. Even if the lower extremity skeletal alignment is wrong with 8-step walking regardless of the O-shaped knee, the X-shaped knee or the lower extremity skeletal alignment, the heel lands on the ground and moves the center naturally toward the lower hardness. And the hardness between the inner portion 110 and the outer portion 130 of high hardness is guided to the low hardness portion to represent the movement trajectory 160 of the ideal ground reaction (pressure) center point, and the inside and outside of the load acting on the feet and knees. The balance is adjusted.

The person with the lower bone skeletal alignment of the O-shape knee is customized to the hardness of the sole of the shoe with the outer support 130, the inner support 110 and the center 120, and the lower skeleton of the X-shaped knee. The person having the alignment can double the effect by tailoring the hardness of the shoe sole to the inner support (110) > outer support (130) >

Differences in the hardness of the shoe sole 100 may be configured to vary the hardness of each part using the same material with different molding compression ratio during molding. For example, the thickness of the synthetic resin material before the sole is made of 4 cm for the inner support 110, 5 cm for the central 120, and 6 cm for the outer support 130, and the thickness of the finished sole is maintained at 3 cm for each part. When compressing, the compression ratio of each part will be different, resulting in the hardness difference of the finished product. The hardness is also applied in the same manner as in the first embodiment when fabricating with a different compression ratio.

 The hardness of the shoe sole 100 can also be adjusted by the amount of foaming agent included in the material. When manufacturing a shoe sole, increasing the amount of blowing agent increases the air contained in the blowing agent, so the hardness is low, and if the amount of blowing agent is low, the hardness is increased.
