Description

Insoles for body correction

Technical Field

The present invention relates to an insole for body correction, and in particular to an insole for body correction that can allow pedestrians to quickly recover (relax) from bending, twisting, twisting or bending of the lower body (pelvis, knees or ankles) while walking normally, and can keep walking with the pedestrian's spine straight.

Background technique

Generally, walking involves repetitive movement of the lower limbs to move the body forward.

That is, when the body moves forward, one lower limb supports the movement while the other lower limb moves forward. When the weight of the body is transferred from one lower limb to another, both feet remain attached to the ground. As the role of each lower limb is switched, the gait cycle is repeatedly performed until the goal is reached.

When walking, the gait cycle is divided into a stance phase and a swing phase.

For example, the stance phase is the process from right heel contact to right toe lift, which occurs when the sole of the right foot contacts the ground and supports the body weight.

The swing phase is the period from when the right toe is lifted to when the right heel touches the ground again. This is the period when the right foot is in the air and the foot moves forward until it touches the ground again.

At normal walking speed, the stance phase accounts for approximately 60% of the gait cycle, and the swing phase accounts for the remaining 40%.

Most problems that occur in the lower extremities during the gait cycle occur during the stance phase due to the amount of impact caused by weight bearing.

It is understood that pedestrians will generate an impact of 1 to 2 times their body weight when walking, and 2 to 3 times their body weight when running. This impact acts in the form of stress, and excessive stress accumulation can cause damage to the feet.

At the same time, many body imbalances occur, not only when walking, but also when sitting in a chair for a long time, because of the habit of unbalanced posture, the body will lean to one side.

Representative symptoms caused by this imbalance in the body are scoliosis and kyphosis, which are symptoms of asymmetric imbalance.

Scoliosis is an imbalance symptom that occurs when the symmetrical center line of the toes of both feet twists toward 11 o'clock or 1 o'clock, while the corresponding upper body twists in the opposite direction like a twist.

Kyphosis is a condition in which the spine curves backward when viewed from the side, which can cause twisting of the ankle joints, pelvic distortion and spinal deformity, leading to pain in the neck, lower back, pelvis, knees or feet.

Methods for correcting body imbalances include corrective surgery and the use of corrective devices.

The method using corrective surgery is not preferable in terms of surgical side effects and costs, and the method using orthodontic appliances has a problem of causing much inconvenience to daily life due to wearing the appliances for a long time.

Recently, the development of technology for using insoles as orthotic devices has been actively carried out.

However, most technological developments have focused on functionality such as the hardness of insoles or cushioning or shock absorption due to insert structures, while technological development for correcting body imbalances that cause symptoms such as scoliosis remains insufficient.

In order to meet the demand for the development of technology for correcting body imbalance, the patent document 1 previously applied by the present applicant (Korean registered patent number 10-2049077) discloses an insole for body correction, which is characterized in that:

A bottom plate having a first point where the outside of the heel contacts during normal walking and a second point where the pedaling pressure is transferred from the rear foot to the forefoot; and a top plate stacked and installed on the upper surface of the bottom plate, wherein the portion corresponding to the metatarsal bone is inclined from the outside to the inside at an angle of 13° to 14°, the top plate having an upwardly inclined surface, a virtual reference line passing through the first point and the second point forming an angle of 30° relative to a virtual reference line parallel to the length direction of the bottom plate, and having an inclined surface extending upward in an inner direction from the boundary of the reference line with the virtual reference line as the boundary, and the angle of the inclined surface formed on the calcaneus between the first point and the second point is formed to be 16° to 20°.

In addition, for feet with abnormal ankle movement during walking, bending, twisting, twisting or bending based on the sagittal plane (the plane that divides the body into left and right sides) is induced to maintain walking. At this time, the pedestrian's lower body naturally produces an internal rotation phenomenon in which the foot bends inward to disperse the load on the ankle.

That is, pedestrians with abnormal ankle motion will naturally attempt to maintain balance in the lower body and spine by naturally pronating to compensate for external imbalances in the lower body (pelvis, knees, or ankles).

However, in the above-mentioned Patent Document 1, even if adduction does not occur in a stationary state rather than in a walking or running state, the spine can be straightened by inducing the pelvis or ankles to return to their original positions and straighten them, and it has a slope that is inclined inward and upward from the boundary of the baseline at an angle of 30° to the horizontal virtual line based on the length direction of the base plate, so that when walking or running, the area of contact with the heel bone of the pedestrian is increased, resulting in external imbalance of the lower body (pelvis, knees or ankles), thereby causing foot fatigue.

In particular, as mentioned above, in order to recover the foot fatigue accumulated due to external imbalance when walking or running, the recovery time for the bent or twisted lower body and spine to straighten again will of course be prolonged, and in order to compensate for this, adduction occurs and the muscles around the hip joints become strongly tense, which increases the pressure on the joints or spine of the pedestrian, so that when people walk or run with increased overall muscle tension, the spine cannot be expected to be corrected, and there is a problem that walking or running must be maintained in a more bent or twisted state.

Detailed ways

Hereinafter, the structure and operation of specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

At this time, when adding reference numerals to components in each drawing, it should be noted that even if the same component is shown in different drawings, it is indicated by the same reference numeral as much as possible.

Furthermore, when describing the present invention, detailed descriptions of related well-known functions or structures will be omitted to avoid obscuring the gist of the present invention.

In addition, when a component “includes” a certain component, it means that other components may also be included, rather than excluding other components, unless explicitly described otherwise.

In describing the present invention, the width direction is based on the direction of the sole (horizontal direction with respect to FIGS. 2 to 4 ), and the length direction will be described based on the direction perpendicular to the width direction.

In addition, the expression "inside" refers to the inner direction of each component or divided by each component or a position in this direction, and the external expression will be explained as a region in the opposite direction to the internal expression or in its direction.

The present invention relates to an insole for body correction, and in particular to an insole for body correction that can allow pedestrians to quickly recover (relax) from bending, twisting, twisting or bending of the lower body (pelvis, knees or ankles) while walking normally, and can keep walking with the pedestrian's spine straight.

To this end, as shown in FIGS. 1 to 4 , the structure of the insole for body correction according to the present invention may include a bottom plate 11 and a top plate 12 .

First, as shown in FIGS. 1 to 3 , the base plate 11 of the present invention compensates for the pressure concentration of about 30° from the outside to the inside of the foot when taking a step, and compensates for the collapse angle of the calcaneus (one of the tarsal bones in the heel area), for example, 16° to 20°.

The base plate 11 is used to disperse the pressure concentrated at an angle of 30° from the outside to the inside of the foot when taking a step, providing uniform pressure for the entire foot, including a first point f1 where the outside of the heel contacts and a second point f2 where the pedaling pressure moves from the rear foot inward to the front foot, and a structure having an asymptotic line as a reference line 13 with an upward inclination toward the inside of the base plate 11.

That is, after taking a step with the heel, the inner side of the calcaneus touches the ground and walking begins. After the calcaneus steps out, the forefoot steps. The second point f2 refers to the boundary area of the hindfoot before the arch of the foot begins.

There may be some individual differences based on the structural characteristics of the arch of the foot, but when walking, the pressure on the sole of the foot will cause it to tilt about 30° from the outside to the inside, causing an unbalanced posture that tilts from the outside to the inside.

Therefore, in the present invention, the first point f1 and the second point f2 are connected to the base plate 11 with the virtual line 14 as the reference line 13, and an upward inclined surface 11a is formed on the inner side of the reference line 13, that is, starting from the reference line 13, and the pressure is distributed from the inner side to the outer side of the base plate 11 with the reference line 13 as the boundary.

This allows uniform pressure to be applied to the entire foot during walking, thereby inducing normal walking.

Specifically, in the present invention, as described above, in order to overcome the problems or limitations of the prior art in the "Korean Patent Publication No. 10-2049077 (published on November 26, 2019)" previously submitted by the applicant, unlike the existing virtual line horizontal to the length of the base plate 11, the virtual baseline 13 passing through the above-mentioned first point f1 and the second point f2 is horizontal to the point formed by the virtual line 14 in the width direction of the base plate 11.

Therefore, when walking or running with the existing insole, the area of contact with the pedestrian's heel bone increases, causing external imbalance of the lower body (pelvis, knees or ankles), which can solve the problem of accumulated foot fatigue.

In addition, in order to recover the foot fatigue accumulated due to external imbalance when walking or running, the recovery time for the bent or twisted lower body and spine to straighten again becomes longer. To compensate for this, adduction occurs and the muscles around the hip joint become strongly tense, which increases the pressure on the walker's joints or spine. When the overall muscle tension increases when people walk or run, spinal correction can also solve the problem of having to maintain walking or running movements in an unexpectedly more bent or twisted state.

Referring to Figures 5 and 6, Figure 5 is a graph for illustrating the bending of a pedestrian's ankle and the recovery speed of the bending when walking in a conventional insole, and Figure 6 is a graph for illustrating the bending of a pedestrian's ankle and the recovery speed of the bending when walking in an insole for body correction according to the present invention.

That is, FIG. 5 and FIG. 6 show the bending rotation of the pedestrian's ankle, and the red frame portion in the figure represents the angular velocity (recovery speed). The longer the frame and the sparser the points, the faster the angular velocity (recovery speed).

By comparing FIG. 5 and FIG. 6 , it can be seen that when wearing the insole for body correction according to the present invention, the recovery speed of ankle flexion (bending) deformation is significantly faster than wearing the existing insole, which confirms that the limitations of spinal correction caused by walking with bent ankles due to accumulated fatigue of the existing insole have been resolved.

In addition, referring to Figures 7 and 8, Figure 7 is a graph for illustrating the deformation of the pelvis of a pedestrian when walking in a conventional insole and the recovery rate of the deformation, and Figure 8 is a graph for illustrating the deformation of the pelvis of a pedestrian when walking in a body correction insole according to the present invention and the recovery rate of the deformation.

That is, FIG7 and FIG8 show the twisting rotation of the pedestrian's pelvis. The red frame portion in the figure represents the angular velocity (recovery speed). The longer the frame is and the sparser the points are, the faster the angular velocity (recovery speed) is.

By comparing Figures 7 and 8, it can be seen that when wearing the insole for body correction of the present invention, the recovery speed of the pelvic torsion (bending) deformation is significantly faster than wearing the existing insole, which confirms that the limitations of spinal correction caused by the accumulated fatigue caused by the existing insole, which leads to the twisted pelvis when walking, have been resolved.

9 to 11, there are pictures taken from a video for illustrating deformation of a body when walking while wearing a conventional insole and an insole for body correction according to the present invention. From the pictures, it can be seen that the conventional insole is worn on the left side, and the insole for body correction according to the present invention is worn on the right side.

Thus, even with reference to FIGS. 9 to 11 , when walking in conventional insoles, external imbalance (bending, twisting, twisting or bending) of the pedestrian's lower body (pelvis, knees or ankles) may occur, and the induced adduction/addition phenomenon may be confirmed.

On the other hand, when walking while wearing the insole for body correction according to the present invention, the above-mentioned external imbalance (bending, twisting, twisting or bending) phenomenon recovers faster, and it can be confirmed that the pedestrian can keep walking with the lower body and spine straight.

Meanwhile, the base plate 11 of the present invention is used to compensate for the collapsed angle of the calcaneus of the sole of the foot. Preferably, the inclination of the calcaneus between the first point f1 and the second point f2 of the base plate 11 is 16° to 20°.

In this way, the angle of the calcaneal collapse after taking a step while walking is in the range of 16° to 20°. Therefore, in the present invention, the calcaneal between the first point f1 and the second point f2 of the base plate 11 compensates for this by setting the upward inclination to 16° to 20°, which can achieve the effect of straightening the spine.

For example, if the calcaneal tilt exceeds 16° to 20°, the anterior pelvic tilt becomes severe, correction of the side-to-side sway becomes difficult, and hip rotation of the leg may increase.

In addition, the thickness of the bottom plate 11 of the present invention outside the reference line 13 is 0.5 to 1.0 mm, preferably the same as or as close as possible to this thickness, but the thickness of the outer part of the bottom plate 11 forms the same thickness within an error range of 0.1 to 0.2 mm.

In addition, the inclined surface 11 a formed on the calcaneus between the first point f1 and the second point f2 may be formed as the inclined surface 11 a inclined upward toward the outside with a thickness of 1.0 mm to 2.8 mm.

In this way, the present invention improves the structure of the base plate 11, compensates for the 30° pressure applied from the outside to the inside when walking, so that the entire foot is subjected to uniform pressure from the beginning of putting on the shoe, thereby inducing stable and normal walking, and by compensating for the angle of heel bone collapse when walking (16° to 20°), the spine is straightened when walking or running, preventing and preventing the occurrence of body imbalance.

At the same time, as shown in Figures 1 and 4, the top plate 12 of the present invention is located on the bottom plate 11 and combined to form a stack. The portion corresponding to the metatarsal has an inclined surface with an angle of 13° to 14° upward from the outside to the inside, and is made of a material softer than the bottom plate 11.

That is, the bottom plate 11 of the present invention is made of a relatively hard material so that the calcaneal angle (advance angle) of 16° to 20° does not collapse, and the top plate 12 is made of a relatively softer material than the bottom plate 11 to cushion and absorb shock.

For example, the top plate 12 may be made of an elastic and soft material such as polyurethane, rubber, or silicone to closely adhere to the curved surface of the bottom plate 11 . In addition, any material softer than the bottom plate 11 may be used.

And, as shown in FIG. 4 , the top plate 12 is used to improve a windlass mechanism, and a region corresponding to the metatarsal bone is formed as an inclined surface having an upward inclination of 13° to 14° from the outside to the inside of the top plate 12 .

For example, one may have a structure that slopes upward from the fourth or third metatarsal to the first metatarsal (big toe).

Additionally, the winch mechanism serves to maintain the medial arch of the foot while walking, meaning that effective movement of the plantar fascia and spring ligaments produces movement of the ankle joint, which creates a winch effect on the foot.

Like the top plate 12 according to the present invention, the area corresponding to the foot bone is formed as an upward inclined surface with an angle of 13° to 14° from the outside to the inside of the top plate 12, so that when the foot is lifted after stepping on it, the hoisting mechanism can be improved by increasing the rolling effect of the foot.

For example, if the slope is less than 13°, the calf muscles may be strained when walking, and if it exceeds 14°, pain may occur in the sole of the foot, especially the first metatarsal bone, when walking.

The present invention has been shown and described above with reference to specific embodiments, but the present invention is not limited to the above embodiments, and various changes and modifications may be made without departing from the technical idea of the present invention.
