Abstract

본 발명은 에어쿠션형 신발중창에 관한 것으로, 특히 보행시 단순한 공기충진부를 설치하는 것이 아니라 이 공기 충진부에 탄성부재를 함께 일체로 구성하므로서 흡입된 공기의 흐름이 이들 탄성부재내를 관통하면서 공기의 흐름을 어느정도 억제하는 동시에 일정한 공기압이 유지되도록 흡입구와 배출구에 밸브장치를 함께 설치하였다.The present invention relates to an air cushion-type shoe sole, and in particular, it is not provided with a simple air filling unit when walking, but by forming an elastic member together with the air filling unit, the flow of inhaled air penetrates the inside of the elastic member. Inlet and outlet valves were installed together to suppress the flow of water to maintain a certain air pressure.

따라서 보행시 흡입공기와 배출공기의 조화에 의하여 안정된 쿠션감을 주며, 공기는 신발중창를 통하여 신발내부로 유통하면서 신발내부의 발에 대한 공기순환효과도 보게하였다.Therefore, it provides a stable cushion by the combination of intake air and exhaust air during walking, and the air is distributed to the inside of the shoe through the shoe midsole, and the air circulation effect on the foot inside the shoe is also seen.

또한 다수의 공기충진된 탄성부재는 자체적인 탄서이 압박에 의하여 무너지지않고 공기를 함께 연행하고 있어 구조유지가 장시간 가능하게 된다는 특징이있다.In addition, many air-filled elastic members are characterized by being able to maintain their structure for a long time because their tannery is entrained with air without being collapsed by pressure.

Description

에어쿠션형신발중창{Shoes medium sole containing air-cushion }Shoes medium sole containing air-cushion

본 발명은 2중의 에어쿠션형 신발중창에 관한 것이다. 특히 상하만곡형 저장부를 일체화하되 중간의 공간부에 T.P.U(thermal plastic rubber), P.V.C, 우레탄등의 탄성부재를 적층하도록 하고, 이 탄성부재에 일정량의 공기가 순환유통가능하도록 하되 공기의 순환과 탄성부재의 탄성이 융합된 새로운 에어쿠션형 신발중창에 관한 것이다.The present invention relates to a dual air cushion type sole. In particular, the upper and lower curved storage unit is integrated, and an elastic member such as TPU (thermal plastic rubber), PVC, urethane, etc. is laminated in the middle space, and a certain amount of air can be circulated through the elastic member. A new air cushion type midsole in which the elasticity of the member is fused.

종래의 많은 쿠션 기능의 신발, 구두에 사용된 쿠션 기능들은 그 내부에 액체 및 공기를 채워 넣어 쿠션감을 주고있다. 그러나 이들 제품은 에어만 충진한 경우 튜브내의 공기의 흐름이 너무 빨라 과다한 압력으로 밸브가 압력을 견디어 내지 못해 제 기능을 못하거나 튜브내의 공기가 빠져 나가거나 파손되며 기후의 영향에 의하여 탄력성이 불균일해지고 공기가 빠지면 재주입을 해주거나 다른 조치를 해야하며, 장시간이 경과하면 쿠션감이 떨어지는 문제점이 있었다. 또다른 방법으로 튜브 내에 질소가스를 넣어 밀봉하고 이를 중창몰드나, 밑창몰드에 매설하여 두꺼운 층을 형성하여 성형하여 해결하였으나 이로 인해 에어쿠션의 본래의 기능을 얻기가 어려웠다. 기능만 에어쿠션이고 실제품은 우리가 사용해본 대로 일반 신발, 구두와 별 차이가 없는 문제점이 드러났다.Many conventional cushion-function shoes, cushion functions used in the shoes to give a sense of cushion by filling the liquid and air therein. However, when these products are filled with air only, the flow of air in the tube is so fast that the valve can not withstand the pressure due to excessive pressure, and the air in the tube is leaked or broken, and the elasticity becomes uneven due to the influence of the climate. If the air is missing, re-injection or other measures have to be taken, and there was a problem that the cushion feeling falls after a long time. In another method, the nitrogen gas was sealed in the tube and embedded in the midsole mold or the sole mold to form a thick layer to solve the problem. However, it was difficult to obtain the original function of the air cushion. The only function is the air cushion, and the actual product showed the problem that there is no difference between ordinary shoes and shoes as we used.

한편, 일본 공개특허공보 소62-246301호에는 솔(Sol)부재가 과압하의 공기를 수용하도록 동작하는 복수의실과 상기실에 접속되어 발에의해 조작되는 급기장치로 되고 상기급기장치가 구면상의 족범위에 의해 부하되고 상측부분의 저부분의 범위의 아래에 배치되는 실체와 저부분에 대항하여 배치된 실옥근(實屋根)에 의해 압축실을 제한하게 되고 상기 압축실이 급기개구 및 흡기변을 개재하여 외부의 공기와 또 배기개구 및 배기면을 개재하여 상기실과 접속되어 있는 형태로 구성되어 있으며 압축실이 부하를 가하는 족범위의 구변성에 일치된 반렌즈형의 요부로 되어 구성되고 흡기개구 및 배기개구가 압축실의 중앙범위에 배치되어 구성되는 운동화가 알려지고 있다.On the other hand, Japanese Patent Laid-Open No. 62-246301 discloses a plurality of chambers in which a sole member is operated to receive air under overpressure, and an air supply device connected to the chamber and operated by a foot, and the air supply device is spherical.
