Definitions
- the present invention relates to a shoe sole member that is provided on the bottom surface of a heel portion of a shoe sole so that a rotational torque is generated in a horizontal direction with respect to a ground contact surface by weight pressure at the time of ground contact.
- knee movement includes bending and stretching (flexion / extension), and further, sliding and rolling motion is performed on the joint surface of the knee.
- the knee joint is a lower limb load joint and plays an important role in supportability and mobility.
- the structure of the knee joint is the joint between the femur and the tibia's patella, and the portion where the bones touch each other is covered with articular cartilage so that the bones do not rub against each other directly.
- a crescent-shaped cartilage called a meniscus is sandwiched between the femur and the tibia, and has a buffering action to absorb impact.
- the impact load applied to the joints during walking is said to be three times the body weight, but during normal walking, the tibia rotates outwardly and absorbs the impact of the femur.
- the external rotation of the tibia relative to the femur is called a screw home movement, which can provide stability during stance.
- the knee extension that does not rely on muscle strength during a long standing posture is stably maintained by the external rotation of the lower leg about 5 degrees with respect to the thigh. .
- Knee osteoarthritis is a degenerative disease in which pain is caused by abrasion or deformation of the knee articular cartilage due to an excessive load exerted on the knee joint.
- a reverse screw-home movement occurs in which the lower leg part rotates inward with respect to the thigh when the knee joint extends, and the knee joint is pushed outward (thrust movement) in the early stage of stance walking.
- Occurs changes in lower limb alignment (skeletal arrangement) and abnormal movement appear.
- the present invention attaches to the bottom surface of the heel part of the shoe sole and generates a gentle rotational torque while securely mitigating the impact force when the heel part touches down.
- PROBLEM TO BE SOLVED To provide a sole member that can surely suppress the progression of arthropathy and can walk comfortably without a sense of incongruity even when used by a healthy person to prevent knee osteoarthritis. To do.
- the present invention includes a base fixed to the bottom surface of the heel of the shoe sole, and projects radially extending from the base while inclining in the same direction toward the grounding direction.
- a plurality of elastic ribs arranged at predetermined intervals in the circumferential direction, and each rib tilts due to body weight pressure at the time of grounding to generate rotational torque horizontally with the ground contact surface
- each rib is formed in a shape curved in the radial direction.
- the shoe sole member of the present invention is attached and fixed to the bottom surface of the heel portion of the shoe sole via the base, and a plurality of ribs project toward the ground contact direction.
- the ribs are inclined in the same direction toward the grounding direction, and extend radially to be arranged in the circumferential direction.
- each rib is formed in a shape that is curved in the radial direction. Due to this curved shape, the ribs are arranged in a substantially spiral shape. As a result, each rib has moderate stiffness, and it does not bend sharply from its root and tilts while walking. ⁇ Each rib tilts while gradually squeezing according to the body pressure that gradually increases when touching the ground. This will surely reduce the impact when touching the ground.
- each rib has a curved shape, each rib gradually tilts while squeezing according to the body pressure, which increases gradually when the heel touches with walking, thereby increasing the rotation angle, and a gentle rotational torque. Can be generated.
- a smooth screw home movement can be generated at the time of heel contact and a high shock-absorbing effect can be obtained, thereby reducing the burden on the knee joint and ensuring normal walking.
- the progression of knee osteoarthritis can be reliably suppressed.
- a gentle rotational torque is generated at the time of ground contact, so that I's walking comfortably. Therefore, it can be suitably used for prevention of knee osteoarthritis.
- the shoe sole member of the present invention can be molded with a material such as natural rubber, synthetic rubber, or synthetic resin.
- the inclination angle of the rib of the present invention can be appropriately selected in consideration of rotational torque and cushioning to the knee joint, which are preferably in the range of 60 degrees or more and less than 90 degrees with respect to the base.
- the material hardness, the degree of rib curvature, the rib inclination direction, the rib inclination angle, the rib thickness, and the number of ribs are appropriately selected according to the symptoms of knee osteoarthritis. be able to.
- the base when the shoe sole member of the present invention is attached to the bottom of the heel of the shoe sole, the base may be fixed to the shoe sole via an adhesive, or may be integrally formed with the heel of the shoe sole. It may be provided.
- the sole member may be detachably attached to the sole by screwing the base to the sole or by providing a hook-and-loop fastener between the base and the sole.
- the plurality of ribs include a first rib having a predetermined length in the radial direction and a second rib shorter than the first rib.
- the first rib and the first rib The two ribs are arranged alternately in the circumferential direction, and the second ribs are arranged radially outward with respect to the first ribs.
- the ribs extend radially and are arranged in the circumferential direction, the distance between the ribs is wider than the distance between the ribs on the inner side in the radial direction. For this reason, the elasticity per unit area obtained by each rib is smaller on the outside in the radial direction than on the inside. Therefore, in the present invention, by arranging the second ribs closer to the outer side in the radial direction and interposing them between the first ribs, the elasticity per unit area can be uniformly generated as a whole. As a result, it is possible to evenly absorb the impact when landing on the heel and disperse it efficiently in the rotational direction, and to reliably reduce the burden on the knee joint when the user walks.

- the portion where the inclined surface of the second rib is formed can be squeezed flexibly so that foreign matter such as pebbles can be smoothly ejected.
- irregularities are formed on an edge surface serving as a ground contact surface of the rib.
- the ribs protrude a predetermined amount from the bottom surface of the heel portion of the shoe sole, and at least the arrangement circumference of each rib.
- the center part of is placed so as to correspond to the lowest point of the rib.
- each rib protrudes by a predetermined amount from the bottom surface of the heel of the shoe sole, the rotation of each rib is smoothly generated without being obstructed by the ground contact of the bottom surface of the heel portion of the shoe sole. You can make it S. Further, by positioning the central portion of the array circumference of each rib corresponding to the lowest point of the rib, a relatively large amount of rotation can be obtained with the tilt of each rib. Note that the position corresponding to the lowest point of the rib usually corresponds to the position 14 to 17% of the foot length from the rear end of the foot heel to the toe side.
- a disc-shaped ground plate connected to the ground side of each rib and covering the lower side of the array circumference of each rib and facing the base may be provided.
- each rib can be uniformly tilted through the ground plate, and a stable rotating torque can be generated.
- the ground plate is exposed from the bottom surface of the heel of the shoe sole. Since the rib is concealed between the base and the ground plate, it is possible to more reliably prevent intrusion of foreign matters such as pebbles between the ribs.
