Description

Outsole Having Inclined Plane and Correcting Lower Extremity Misalignment and Knee Joint Osteoarthritis Shoes Involving This}

The present invention relates to a sole having an inclined surface and a knee joint including the same, and more particularly, an inferior lower limb skeletal alignment is corrected while the foot is inclined or slipped inward or outward by an inclined surface formed on the sole so that the knee joint is deflected. The present invention relates to an outsole having an inclined surface for preventing and pain relief of degenerative knee arthritis by uniformly distributing the load applied thereto, and to a knee joint including the same.

The knee joint is a part that balances the weight of the body to be supported by four feet so that it can stand without falling down. Therefore, the knee joint is moving little by little to balance the body even when we are not aware of it.

At this time, most ideally, the center of the weight should pass through the center of the knee joint, but most people do not pass the center of the knee joint, so large loads continue to act as part of the knee joint. Because of this, the knee joint is one of the areas where the degenerative change occurs with age. In addition, incorrect walking habits result in abnormal lower extremity skeletal alignment, which causes large loads to continue to act as part of the knee joint.

Degenerative knee osteoarthritis may cause symptoms such as knee pain when standing up, trembling knees when standing, sound when bending or spreading knees, or gaping between one or more fists in a standing position. . In addition, it is a disease that can be suspected when symptoms such as pain is particularly severe when going down the stairs, or pain that occurs after walking for more than two days to three days.

The goal of treating arthritis is to reduce pain and increase joint flexibility. Most arthritis cannot be cured. For milder symptoms, pain and stiffness can be alleviated with constant physical therapy, medication, or weight loss. However, patients with severe arthritis can reduce pain through surgery or restore joint function through reconstruction. However, such surgery is not only expensive but also cumbersome, and therefore, many people cannot operate.

1 is a front view showing the right lower limb alignment of the "O" shaped knee, and FIG. 2 is a front view showing the right lower limb alignment of the "X" shaped knee. As shown in FIGS. 1 and 2, in the lower limb alignment (1) of a person with an "O" shaped knee and the lower limb alignment (9) of a person with an "X" shaped knee, the mechanical axis 50 is the femoral head center. (3) shows a line connecting the center of the head (5), the bending axis 70 means a line connecting the center of the femoral head (3) and the center of the knee joint (7).

Genu Varum, commonly referred to as an "O" shaped knee, is an "O" shaped knee that does not stick to each other when the legs are brought together when the bending axis 70 is inclined out of the mechanical axis 50. Refers to legs bent in shape. Genu Valgum, which is referred to as an "X" knee, refers to a leg that is bent out of the knee joint when standing with both legs together when the bending axis 70 is inclined inward of the mechanical axis 50. The larger the value of the inclination angle β between the bending axis 70 and the mechanical axis 50, the more severe the "O" -shaped knee and the "X" -shaped knee.

Abnormal lower extremity skeletal alignment, such as "O" and "X" knees, may be caused by congenital or acquired factors, causing load to concentrate on one part of the knee joint, resulting in degenerative knee arthritis or worn out knee joints. Happens.

In order to alleviate and prevent the pain of degenerative knee arthritis and to correct abnormal lower limb skeletal alignment, shoes are formed so that the foot is inclined inward during walking.

3 is a rear view of a shoe worn by a person with a conventional abnormal lower limb skeletal alignment or a person with degenerative knee arthritis. As shown in FIG. 3, when the foot is walking on the ground 500 wearing the shoe 10 by forming the shoe 10 including the sole 14 and the upper 12 formed such that the foot is inclined to the inside of the shoe. The legs and legs themselves were inclined to the inside of the shoe and the rotation of the knees was moved inward to correct abnormal lower limb skeletal alignment or to treat degenerative knee arthritis.

However, when walking with these shoes 10, due to the inclination of the sole 14, the foot slips excessively inward, causing excessive shear force on the ankle and knee joints, and excessive force on the leg to prevent the foot from slipping. When applied, strong loads are applied to the inner parts of the feet and knees, which can worsen degenerative knee arthritis.

Therefore, the present invention was created to solve the above problems, the foot is inclined or slipped inward or outward by the inclined surface formed on the sole correcting the abnormal lower extremity skeletal alignment, uniformly applied to the load applied to the knee joint deflected It is an object of the present invention to provide an outsole having an inclined surface for the prevention and pain relief of degenerative knee arthritis and the knee joint including the same.

An object of the present invention as described above is in the sole attached to the bottom of the shoe, the sole is inclined structure formed by the upper surface and the bottom surface is formed in parallel, including the upper member and the lower member partitioned by the inclined surface formed in the width direction By the sole having the inclined surface, characterized in that the deformation member for generating a shear deformation in the inclined direction between the upper member and the lower member is provided in the remaining portion except for a predetermined distance from both the front and rear ends of the longitudinal direction of the shoe Can be achieved.

In addition, the inclined structure is formed such that the inclination of the inclined surface becomes larger toward the rear in the longitudinal direction of the shoe.

Further, the inclined structure is formed by inclining the inner side of the sole by the inclined angle α in the outer side direction or the outer side in the inner side direction so that the cross section in the width direction becomes the inverted trapezoidal shape. At this time, the inclination angle α is 0 ° to 60 °.

As another category, the object of the present invention can be achieved by knee arthrosis, characterized in that it comprises a sole having the aforementioned inclined surface.

According to the present invention, by uniformly distributing the load applied to a part of the knee to alleviate the pain of degenerative knee arthritis, it is possible to prevent the occurrence of knee arthritis in advance.

In addition, those who have "O" and "X" knees, which are out of the normal lower extremity skeletal alignment, can select soles suitable for the shape of the legs and apply shoes to them to correct misalignment. It works. This corrects the wrong leg shape and establishes the correct pace and correct body structure.

The inner varnish described in the present invention refers to a leg that is bent outwardly in an "O" shape without the knees sticking to each other when the two legs are put together, and is generally referred to as an "O" shaped knee. In addition, the valgus is referred to as a leg bent out of the knee joint when standing with both legs together, generally referred to as "X" knee.

In addition, a person having an "O" shaped knee as described in the present invention is a person who has a congenital lower limb skeletal alignment or an acquired lower limb skeletal alignment is "O" shaped and a person having pain in the inner knee. It includes everything. In addition, a person with an "X" shaped knee includes both a person with a congenital lower extremity skeletal alignment or an acquired variant with an "X" shaped lower extremity skeletal alignment and a person with pain outside the knee.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

<Configuration of the sole>

(First embodiment)

4 is a perspective view of the sole for the wearer of the person having an "O" shaped knee according to the first embodiment of the present invention, Figure 5 is a wearer of a person having an "O" shaped knee according to the first embodiment of the present invention 6 is a left side view of FIG. 5, and FIG. 7 is a right side view of FIG. 5. 4 to 7, the sole 320 according to the first embodiment of the present invention is the upper member 322, the lower member 324 and between the upper member 322 and the lower member 324 It consists of a deforming member 323 is provided.

As shown in FIGS. 4 to 7, the sole 320 according to the first embodiment of the present invention has an arch-shaped dome having a shape corresponding to an arch formed at the center of the sole of a person on one side of the bottom surface of the sole 320. Is formed. Such an arched dome is preferably formed at a position corresponding to the arch portion formed on one side of the center of the shoe, preferably the sole of the person.

8 is a cross-sectional view taken along line AA of FIG. 5, and FIG. 9 is a perspective view of a lower member according to the first embodiment of the present invention. As shown in FIGS. 8 and 9, the lower member 324 according to the first embodiment of the present invention has an overall bottom surface parallel to the ground, and the upper surface is arched along the length direction of the sole 320. Is done. In addition, as shown in FIG. 8, inclined surfaces 323a and 323b are formed at one side of the inner side or the outer side of the width direction higher than the other side. Such inclined surfaces 323a and 323b are formed with inclined surfaces 323a and 323b having high inner or outer sides according to the alignment of the lower limbs of the person who wears the shoes. Here, the inside is the direction of the big toe of the person in the width direction, the outside is the direction of the little toe in the width direction. For example, when the height H ₁ of the width direction inner side of the sole 320 and the height H ₂ of the outer side are 1: 1.5 to 1: 2, that is, the inner height H ₁ is 1 cm, the outer side The height of H ₂ is formed to be 1.5cm to 2cm. In this case, the direction and height of the inclined surfaces 323a and 323b may be variously changed according to the skeletal alignment state of the person who wears the shoe or the degree of pain in the knee. The material of the lower member 324 is made of a material having a greater hardness (hardness) than that of the upper member 322.

8 and 9, the height from the ground is the highest on the inclined surface 323b caused by the difference between the inner height H ₁ and the outer height H ₂ of the lower member 324. The lower trough is made to be formed on the inner side of the sole 320 so that a person with an "O" shaped knee can wear. That is, when walking in the shoe provided with such a sole 320, since the overall hardness of the upper member 322 is less than the hardness of the lower member 324, the innermost of the sole 320 formed the lowest portion of the inclined surface (323a, 323b) The deformation amount is greater than the outer deformation amount so that the wearer's foot naturally inclines to the inside of the sole 320. As such, when the shoe is continuously worn with the sole 320 according to the present invention, the knee and the foot are inclined toward the inside of the body to correct the “O” -shaped knee.

On the contrary, in order for a person having an "X" shaped knee to wear, the bottom of the inclined surface 323b of the lower member 324 is manufactured to be formed outside the sole 320. When the bottom of the inclined surface 323b is formed to face the outside of the sole 320, the wearer's foot is tilted to the outside of the sole 320 on the same principle as the sole 320 for a person having an “O” shaped knee. do.

When the "O" -shaped knee and "X" -shaped knee are corrected by the sole 320 having the above-described configuration, loads concentrated on the inside or outside of the knee are distributed to the entire knee to prevent degenerative knee arthritis, and I can alleviate it.

Deformation member 323 according to the first embodiment of the present invention generates the shear deformation in the inclined direction of the inclined surfaces (323a, 323b). At this time, the deforming member 323 is formed at the same slope as the inclined surfaces (323a, 323b) for partitioning the upper member 322 and the lower member 324. That is, the deformation member 323 slides along the inclined surfaces 323a and 323b by the force applied from the upper part of the sole 320, so that the moment acts inward or outward of the foot of the person who wears the shoe. The lower limb skeletal alignment should be corrected more smoothly. The material of the deforming member 323 is a synthetic resin, rubber or silicone in the form of a gel.

As illustrated in FIG. 8, the sole 320 having the above-described configuration has an inner side of the sole 320 in the outer side direction or an outer side in the inner side direction so that the cross section in the width direction becomes an inverted trapezoidal shape. It inclines by the predetermined inclination angle α. At this time, the inclination angle α is preferably inclined to 0 ° to 60 °. This inclination angle α can be changed depending on the state of the knee and the pain of the person wearing the shoes. However, the preferred inclination angle α is preferably 10 ° to 20 °. If the inclination angle exceeds 60 °, since the change of the sole 320 becomes too severe, the inclination angle α should not exceed 60 °.

In order to wear a person having an “O” shaped knee, as shown in FIG. 8, the inner side is inclined by the inclination angle α with respect to the outer side so that the center of gravity of the upper member 322 and the lower member 324 is increased. The “O” shaped knee is corrected because the sole 320 slips into the body more easily due to shear deformation of the deforming member 323.

In addition, in order for a person having an "X" shaped knee to wear, the outer side is formed to be inclined by the inclination angle α with respect to the inner side as opposed to FIG. 8. When the inclination is formed, the "X" shaped knee is corrected because the center slides out of the body when walking.

(Second embodiment)

Figure 10 is a bottom view of the sole for the wearer of the person having an "O" shaped knee according to a second embodiment of the present invention, Figure 11 is a left side view of Figure 10, Figure 12 is a right side view of Figure 10. 10 to 12, the sole 420 according to the second embodiment of the present invention is the upper member 422, lower member 424 and between the upper member 422 and lower member 424 It consists of a deforming member 423 provided.

FIG. 13 is a sectional view taken along the line B-B of FIG. 10, FIG. 14 is a sectional view taken along the line C-C of FIG. 10, and FIG. As shown in FIGS. 13 to 15, the sole 420 according to the second embodiment of the present invention includes the upper member 422 and the lower member 424 formed by the deforming member 423 partitioned in the vertical direction. It is formed in an inclined structure including. In the present invention, the sole 420 of the inclined structure is manufactured by forming the deforming member 423 to slide inward or outward of the shoe according to the alignment of the lower limbs of the person who wears the shoe.

At this time, the upper surface and the bottom surface of the sole 420, that is, the upper surface of the upper member 422 and the lower surface of the lower member 424 are formed parallel to each other. In addition, the lower member 424 is made of a material having a greater hardness than the upper member 422.

10 to 15 produce the sole 420 such that the bottom of the deformable member 423 is formed inside the sole 420 so that a person having an “O” shaped knee can wear. That is, when walking with shoes provided with the sole 420, since the hardness of the upper member 422 is smaller than the hardness of the lower member 424, the inner deformation amount of the upper member 422 formed with the lowest portion of the deforming member 423. The foot is naturally inclined to the inside of the sole 420 by being larger than the outer deformation amount of the upper member 422. For example, when the height H ₃ of the inner side in the width direction of the sole 420 and the height H ₄ of the outer side are 1: 1.5 to 1: 2, that is, the inner height H ₃ is 1 cm, the outer side The height H ₄ is formed to be 1.5cm to 2cm. If the shoe is continuously walking in this way, the foot is inclined to the inside of the sole 420, and the "O" shaped knee is corrected. In addition, in order to increase the effect of the knee correction may be formed so that the inclination of the inclined surfaces (423a, 423b) increases from the longitudinal front to the rear of the shoe. However, it is apparent that the inclination of the anterior side may be changed more largely according to the degree of knee flexion and the degree of knee pain of the ignition person.

On the contrary, in order for a person having an "X" -shaped knee to wear, the sole 420 is manufactured so that the lowest part of the deforming member 423 is formed outside. When the bottom of the deformable member 423 is formed to face the outer side of the sole 420, the wearer's foot slips outward of the sole 420 on the same principle as the sole 420 for a person having an “O” shaped knee. do.

When the "O" -shaped knee and "X" -shaped knee are corrected by the sole 420 having the above-described configuration, loads concentrated on the inside or outside of the knee are distributed to the entire knee to prevent degenerative knee arthritis, and I can alleviate it.

The deforming member 423 according to the second embodiment of the present invention is provided between the upper member 422 and the lower member 424 to generate shear deformation in the inclined direction of the deforming member 423. At this time, the deformable member 423 is provided in the remaining portion except for a predetermined interval from the front and rear both ends of the longitudinal direction of the shoe. The reason why the deformable member 423 is provided at portions except for a predetermined distance from both front and rear ends is to reduce ankle or knee burden caused by the inclination of the foot as a whole. At this time, the deforming member 423 is formed with the same slope as the inclined surface (423a, 423b) for partitioning the upper member 422 and the lower member 424, respectively 5% to 15 from both ends of the front and rear in the longitudinal direction of the shoe It is provided in the center area except for%. That is, the moment acts on the inside or the outside of the foot of the person who wears the shoe while sliding in the inclined direction by the force applied from the upper portion of the sole 420 so that the lower back skeletal alignment, which has been abnormally deformed, is smoothly and smoothly corrected. . In addition, since the sliding portion in the inclined direction is held at the front and rear ends of the shoe, the burden on the ankle and knee is reduced. The material of the deforming member 423 is a synthetic resin, rubber or silicone in the form of a gel.

As shown in FIGS. 13 to 15, the sole 420 having the above-described configuration has an inner side of the sole 420 with an outer side or an outer side with the inner side of the sole 420 so that the cross section in the width direction has an inverted trapezoidal shape. It inclines by the predetermined inclination angle (alpha) in the side direction. At this time, the inclination angle α is preferably inclined to 0 ° to 60 °. This inclination angle α can be changed depending on the state of the knee and the pain of the person wearing the shoes. However, the preferred inclination angle α is preferably 10 ° to 20 °. If the inclination angle exceeds 60 °, since the change of the sole 420 becomes too severe, the inclination angle α may not exceed 60 °.

13 to 15, the inner side is formed to be inclined by the inclination angle α with respect to the outer side in order to wear a person having an "O" -shaped knee, so that the upper member 422 and the lower member 424 may be inclined. Since the center of gravity does not coincide and the sole 420 slides more easily to the inside of the body by the shear deformation of the deforming member 423, the “O” shaped knee is corrected.

In addition, in order for a person having an "X" shaped knee to wear, the outer side is formed to be inclined by the inclination angle α with respect to the inner side as opposed to FIGS. 13 to 15. When the inclination is formed, the "X" shaped knee is corrected because the center slides out of the body when walking.
