Description

맞춤 인솔 및 이의 제조방법{Customized Insole and Preparing Method Therefor} Custom Insole and Preparing Method Therefor &

본 발명은 맞춤 인솔 및 이의 제조방법, 특히, 착용자의 발 하저부의 아치를 지탱하여 착용자의 보행에서 오는 피로를 저감시키고 활동 건강을 유지시키는 맞춤 인솔 및 이의 제조방법에 관한 것이다.  The present invention relates to a personalized insole and a method for manufacturing the same, and more particularly, to a personalized insole for supporting the arch of the foot of a wearer to reduce fatigue caused by the wearer's walking and to maintain activity health, and a method for manufacturing the same.

신발은 발의 바닥을 지지하는 솔 부분과 발의 윗부분을 감싸는 갑피 부분으로 이루어지고 다시 솔 부분은 지면에 접촉되는 밑창(아웃솔), 밑창에 접합되어 바닥 탄성을 주는 중창(미드솔)과 갑피에 감싸여 지고 중창(미드솔)을 통하여 밑창에 접합되고 발에 접촉되는 안창(인솔)으로 이루어진다.  The shoe consists of a sole that supports the bottom of the foot and an upper that surrounds the top of the foot. The sole is an outsole that touches the ground, a midsole that is joined to the sole, And an insole (insole) joined to the sole through a midsole to contact the foot.

맞춤 신발의 경우 개인의 발 형태에 따라 갑피나 솔 부분을 조정하여 개인의 발 형태에 맞추는 것이 가능하고 규격화되어 대량 생산되는 신발의 경우에도 대략적으로 발의 형태와 크기에 따라 착용 안정감이 있도록 다양한 규격과 조절기구가 구비된 신발이 제공된다. 그러나 이러한 신발의 맞춤은 발의 크기나 외형적인 모양에 치중되는 경향이 있다. 발 하저부의 형태, 특히 발의 아치를 지탱하여 주는 구조가 보행시의 피로 저감이나 다리의 건강에 중요한 요소임에 반하여 아치를 포함하는 발 하저부의 형태는 3차원 형태로 개인마다 제각각으로 규격화하기가 어려운 문제점이 있다.  In the case of custom shoes, it is possible to adjust to the shape of the individual's foot by adjusting the upper and sole parts according to the shape of the individual's foot. Even in the case of a mass-produced footwear of a standardized size, A shoe provided with a regulating mechanism is provided. However, the alignment of these shoes tends to be focused on the size and appearance of the foot. The shape of the foot bottom, especially the structure that supports the arch of the foot, is an important factor in reducing fatigue during walking and the health of the leg, while the shape of the foot including the arch is three-dimensional, There is a problem.

한국특허공개 제 2004-4293호에는 폼 층, 핫멜트 층과 직조층으로 적층된 열 변형 가능한 인솔을 개시하고 있다. 상기 핫멜트 층에는 열가소성인 핫멜트 수지를 사용함으로써 사용 전에 소성 온도 이상으로 예열하여 신발 내에 장착하고 조임으로써 개개인의 발의 하저부에 맞는 인솔을 얻을 수 있다는 것이다.  Korean Patent Laid-Open Publication No. 2004-4293 discloses thermally deformable inks laminated with a foam layer, a hot-melt layer and a woven layer. The hot-melt layer is made of a thermoplastic hot-melt resin, so that it is preheated to a temperature not lower than the firing temperature before use and mounted in a shoe and tightened to obtain an insole suitable for a lower part of an individual's foot.

한국특허공개 제 2010-0088111호에는 발 모양으로 재단된 폼 시트를 예열하여 형틀에 넣고 착용자의 발로 가압하여 맞춤형 인솔을 제공하는 기술을 개시하고 있다.  Korean Patent Laid-Open Publication No. 2010-0088111 discloses a technique of preheating a foam sheet cut in a foot shape and putting it in a mold frame and pressing the foot with a foot of a wearer to provide a customized insole.

그러나 상기 열 변형 맞춤형 인솔은 착용자 개개인 발 하저부와 일치하는 형틀이 제공되지 않고 착용자의 발로만 가압해서는 정확한 형태를 얻을 수 없다. 또한 제조된 인솔이 사용자의 발 형태와 유사하다고 하드라도 중창과는 공극이 생기므로 일반적인 적층 시트 재료는 발을 유지 보호해 줄만큼 강도와 탄력성이 없다. 뿐만 아니라, 폴리우레탄 폼이나 EVA 폼 재료는 열가소성 재료가 아니므로 열 성형에 의하여 변형되면 탄성이 소실되는 경향이 있다.  However, the thermoforming customized insole is not provided with a mold matching with the lower part of the wearer's individual foot, and can not be obtained by pressing only with the wearer's foot. Also, since the produced insole is similar to the shape of the user's foot, even if hard, pores are formed with the midsole. Therefore, general laminated sheet material has not enough strength and elasticity to maintain and protect the feet. In addition, since polyurethane foam or EVA foam material is not a thermoplastic material, elasticity tends to be lost when it is deformed by thermoforming.

본 발명은 착용자 발 하저부의 가장 중요한 위치인 아치부를 꼭 맞게 유지할 수 있는 맞춤 인솔 및 이의 제조 방법을 제공하기 위한 것이다. The present invention provides a customized insole and a method of manufacturing the same, which can keep the arch part as the most important position of the wearer's foot bottom part.
