Sole member

Abstract

A sole member capable of securely suppressing the advancement of a gonarthrosis by fitting to the heel part bottom face of a shoe bottom to gently generate a torque while securely relieving impact force when a heel part touches the ground and also enabling comfortable walking without a sense of incongruity even if a healthy person uses it to prevent the gonarthrosis. The sole member comprises a base (4) and a plurality of ribs (5) with elasticity. For use, the base (4) is fixed to the heel part (3a) bottom face of the shoe bottom (3). While tilting in a same direction, the ribs (5) are projected and radially extended from the base (4) in a ground-contact direction, and disposed on the base at prescribed intervals in the circumferential direction. Since the ribs (5) are formed in a shape curved in a radial direction, they are gradually tilted while deforming by a body weight pressure when they touch the ground to relieve the impact force and gently generate the torque in a horizontal direction relative to a ground-contact surface.

Description

technical field [0001] The present invention relates to a shoe sole member, which is installed on the bottom surface of the heel of the shoe sole to generate torque in a direction horizontal to the ground due to the body weight pressure when the foot is on the ground. Background technique [0002] Usually, when the knee moves, it needs to stretch and bend (bend, extend), and the articular surface of the knee also needs to do sliding and rotating motions. The knee joint is the weight-bearing joint of the lower body and plays an important role in support and movement. The knee joint is the joint between the femur, the tibia, and the kneecap. In order to prevent direct friction between the bones, the joint between the bones is covered with a layer of articular cartilage. In the gap between the femur and the tibia is a crescent-shaped cartilage called the meniscus, which acts as a buffer to absorb shock. It is said that the impact load on the joints during walking is three tim...

AI Technical Summary

Problems solved by technology

However, when each rib bears weight pressure, it tilts from its root at once, so a torque is suddenly generated, and the impact force when the heel hits the ground cannot be sufficiently relieved, so there is a problem that the aggravation of deformed knee joint disease cannot be sufficiently suppressed. Defects

[0009] In addition, although healthy people can prevent deformed knee joint disease after wearing shoes with such a sole member installed on the bottom surface of the heel, as mentioned above, a sudden torque will be brought to the calf when walking, so it will affect the use of The person brings uncomfortable feeling, and there is such a defect that the effect of wearing comfort cannot be achieved.
