Abstract

The present invention provides a shoe sole member mounted on the bottom surface of the heel of the shoe sole. By reliably alleviating the impact force when the heel hits the ground, a gentle torque is generated, thereby effectively suppressing the deterioration of deformed knee joint disease. In addition, healthy people In order to prevent osteoarthritis, you can also walk comfortably without discomfort. It includes a base (4) and a plurality of elastic ribs (5), and the base 4 is fixed on the bottom surface of the heel (3a) of the shoe sole (3) during use. The ribs (5) are inclined in the same direction from the base (4) toward the ground surface, protrude and extend radially, and are arranged at predetermined intervals in the circumferential direction. Each rib (5) is formed in a curved shape in the radial direction, so each rib (5) bends and tilts gradually according to the body weight pressure at the time of landing, thereby mitigating the impact and producing a gentle rotation in the horizontal direction with the ground. moment.

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...

Embodiment Construction

[0033] An embodiment of the present invention will be described with reference to FIGS. 1 to 4 . As shown in FIG. 1 , a sole member 1 according to the present embodiment is attached to a ground of a shoe 2 , that is, a heel 3 a of a sole 3 .

[0034] First, the structure of the sole member 1 will be described.

[0035]The sole member 1 is molded from a rubber composition such as natural rubber or synthetic rubber. As shown in FIGS. 2 and 3 , it has a base 4 and a plurality of ribs 5 (a plurality of first ribs 5 a and a plurality of second ribs 5 b ). The base 4 is in the shape of a flat disc, and its top surface 4a is joined with the sole 3 to form a single body.

[0036] As shown in FIG. 4 , each rib 5 is provided integrally with the bottom surface 4 b of the base 4 , and protrudes while being inclined toward the landing direction (downward). As shown in FIG. 3 , the ribs 5 extend radially, are arranged at predetermined intervals in the circumferential direction, and are c...
