Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shoe midsole, and more particularly, to a shoe midsole using a foamed sheet obtained by foaming urethane and aged for a predetermined period of time.
In general, shoes are worn to protect the foot area of a human body. The shoes are used for sports, shoes to be worn when wearing clothes or suits, safety shoes to be worn when working in the field of machinery or construction, There are various kinds such as mountain climbing and mountain climbing. Most of the shoes have an out-sole which comes into contact with the ground, a mid-sole which is located at the upper part of the floor window to support the foot and improves the fit of the shoe, An upper that covers and protects the foot, and an insole that rests on the midsole and rests on the floor inside the upper, supporting the sole of the human body.
On the other hand, when people jump and jump during heavy exercise, the impact force of up to 7 times to 4 times of weight is generated on the basis of weight, and when landing after leaping in the state of fatigue, the natural shock absorbing action of the body does not function properly It is known to receive greater impact. In addition, recently, the increase of artificial structures has caused many people to move on hard concrete and asphalt. The shock applied to the body through the soles of the feet during walking can cause pain in various joints connected to the foot, .
Therefore, the importance of the shoe midsole that directly affects the foot to protect the foot and the joint from the impact is increasing day by day, and the foot and the soles of the shoe wearer's knee and foot area In order to absorb the transmitted shock, the insole is placed on the inner bottom surface of the shoe, the shoe bottom and the shoe part are made of rubber or foam sponge material having excellent buffering ability, or the elastic restorative material such as air bag or spring As shown in Fig.
However, such a conventional shock-absorbing method can be applied mainly to sports and the like, and it is difficult to apply to a shoe or the like. Particularly, a cushion used in a conventional shoe midsole has a problem in that the shock absorbing ability is poor.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a shoe midsole having excellent shock absorbing performance by using a foam sheet obtained by foaming urethane and aging for a predetermined time.
Another object of the present invention is to provide a shoe soles in which the trunk is removed by using a frame made of FRP or carbon fiber.
In order to achieve the above object, the present invention provides a midsole having a shape corresponding to a bottom shape of a shoe and supporting a foot, A waist attached to the bottom of the texion to support the arch portion of the foot; An abdomen for attaching the waist to the texion; A cushion attached to an upper end of the tact to absorb a shock transmitted to the foot; And a midsole inner skin for attaching the cushion to the texture.
According to another aspect of the present invention, there is provided a fiber reinforced plastic (FRP) or a carbon fiber, which supports the foot without a wrist. A cushion attached to an upper end of the tact to absorb a shock transmitted to the foot; And a midsole for attaching the cushion to the texture.
The cushion is prepared by aging the corn, ginseng, ginseng, danshang, and honeydew powder at room temperature with water, aging the mixture for 1 week, mixing the aged dough with the urethane raw solution, foaming the foams to form a foam sheet, Wherein the urethane raw material solution is an urethane foam sheet obtained by mixing an isocyanate prepolymer of diphenylmethane diisocyanate (MDI) type, a polyether polyol, a chain extender, a blowing agent a blowing agent, a silicone, and a catalyst may be used.
The shoe midsole according to the present invention is excellent in impact absorption performance by using a urethane foam sheet aged in a heat room for 48 hours and not only protects the wearer but also contains a beneficial material such as corn, ginseng, ginseng, By using the foam sheet, there is an effect that the foot odor can be suppressed and the metabolism can be promoted.
In addition, the shoe midsole according to the present invention uses a FRP or a carbon fiber tension to remove the hull, thereby simplifying the process and providing an excellent elasticity of the product. Especially, the antibacterial property and the ventilation property There is an excellent advantage.
