Benefits of technology

The present invention is based on the discovery that reducing impact force against a sealed-in liquid by restraining rapid movement and pressure increase can prevent leakage. The invention achieves this by means of grooves or cuts in the first partition and the second partition that are positioned to avoid overlapping and prevent liquid from flowing directly through the joint between the base plate and cover. The technical effect is improved sealing and prevention of leakage.

Problems solved by technology

However, despite of employment of the above-mentioned means for preventing leakage of liquid, leakage of liquid from the joint between the base plate and the cover has occurred.

Embodiment Construction

[0097]A sole member of footwear according to the present invention will next be described while referring to a shoe midsole, with reference to FIGS. 1 to 7. As shown in FIG. 1, the shoe midsole A according to the present invention includes a base plate 1, a cover 2, a plurality of blades 3, and liquid 4.

[0098]The base plate 1 has a first region 11 having a shape equivalent to a foot sole, and a first horizontal flange portion 12 surrounding the entire periphery of the first region. The cover 2 has a second region 21 which faces the first region 11 of the base plate 1, and a second horizontal flange portion 22 which faces the first horizontal flange portion 12. As is apparent from FIG. 1, the first region 11 of the base plate 1 has a length extending from the heel to the portion near to the roots of the toes, and a width of the portion where foot sole contacts with, when foot sole touches down on the ground.

[0099]As shown in FIGS. 2 to 4, the first region 11 has a concave shape which...

Abstract

A shoe midsole is composed of a base plate (1), a cover (2), a plurality of blades (3), and liquid (4). The blades (3) are formed in such a manner as to rise within a first region (11) of the base plate (1). The blades (3) are each composed of a plurality of flat-shaped blade elements (32, 33) separated each other by slits (31), and are tilted toward the toe side or the heel side. The flat-shaped blade elements (32, 33) are disposed in such a manner as to be divergent toward the toe side or the heel side. The base plate (1) and the cover (2) are joined together, thereby forming a closed space (5), and the liquid (4) is sealed in the closed space.

Description

TECHNICAL FIELD[0001]The present invention relates to a sole member of footwear, and more particularly to a sole member of footwear which absorbs impact during walking while providing feeling of stable, comfortable walking, exhibits a massaging effect through stimulation of the foot sole, and can prevent leakage of liquid sealed therein.BACKGROUND ART[0002]When the heel touches down on the ground, impact force imposed on the heel is said to be about 1.25 times the body weight during walking and about three times during jogging. The impact is transmitted to the heel, the ankle, the knee, and then the waist and imposes loads on these regions. Also, it has been known that, as compared with impact applied when the heel touches down on the ground, impact applied when the toes kick the ground is greater.[0003]Thus, the inventors of the present invention have proposed a shoe insole which disperses and absorbs impact applied to the foot sole when the foot sole lands on the ground during wal...
