본 발명은 신발 밑창에 관한 것으로서, 더욱 상세하게는 바닥창에 중창이 삽입되어 고정되는 중창홈을 형성하고, 중창을 바닥창에 별도의 접착제가 필요없이 간단하게 고정하여 결합작업에 소요되는 시간 및 공정을 대폭 단축시킬 수 있는 신발 밑창에 관한 것이다.The present invention relates to a shoe sole, more specifically, to form a midsole groove that is inserted into the midsole is fixed to the sole, and the time required for the bonding operation by simply fixing the midsole without the need for a separate adhesive and It relates to a shoe sole that can greatly shorten the process.

종래에 구두는 갑피를 형성하여 중창을 갑피의 내측으로 들어가게 하고 갑피의 주연부를 중창의 가장자리에 접착하여 완전 건조하거나 경화시킨 다음 이를 신발밑창에 재접착하거나 경우에 따라 봉제 및 재접착하고 신발밑창과 갑피가 맞닿는 사이에 테두리를 접착하고 구두뒷굽을 부착하여 제조된다.Conventionally, shoes form an upper to allow the midsole to enter the inside of the upper, adhere the periphery of the upper to the edge of the midsole, and completely dry or harden it, then rebond it to the sole of the shoe or, if necessary, sew and re-bond the sole and It is manufactured by adhering the rim between the upper abutment and attaching the shoe heel.

그리고 종래의 신발중창은 합성수지 또는 접착성물질에 함침시킨 부직포이거나 판지로 구성시킨 중창이 있으나 지지력이 부족하고 땀, 습기 및 물등에 의하여 자체의 조직 즉 부직포나 판지중창을 구성하는 섬유를 접착결속하는 접착제가 용해되어 조직간에 접착력이 떨어지고 치밀성을 상실하게 되므로서 조직이 와해되어 지지력을 상실하게 되고 따라서 초기의 신발원형을 유지할 수 없게 됨은 물론 신발수명 또한 짧아지게 된다.Conventional shoe soles have non-woven fabrics or cardboard-made midsoles impregnated with synthetic resins or adhesive materials, but lack the support and bond the fibers that make up their tissues, ie, nonwoven fabrics or cardboard midsoles, by sweat, moisture, and water. As the adhesive is dissolved, the adhesion between the tissues is lowered and the density is lost, so that the tissue is degraded and the support force is lost, so that the initial shoe circle cannot be maintained and the life of the shoe is also shortened.

그밖에도 종래의 신발중창으로 폴리에치렌 또는 폴리푸로피렌쉬트로 된 단일기재나 이 기재위에 연질비닐쉬트 또는 합성수지 저발포쉬트등으로 적층시킨 신발중창은 중창자체의 원형은 지속적으로 유지될 수 있으나 이를 구성하는 폴리에치렌이나 폴리푸로피렌 양쪽 공히 접착성이 극히 불량하여 천연피혁이나 합피로 구성된 갑피와 천연고무 또는 합성고무로 구성한 신발밑창과의 접착력이 불량하여 큰 문제 점으로 지적되고 있다.In addition, a shoe sole layered with a single substrate made of polyethylene or polyfluoropyrene sheet or a soft vinyl sheet or a synthetic resin low foam sheet on the substrate may maintain its original shape. It is pointed out as a big problem because the adhesion between both ethylene and polypropylene is extremely poor, and the adhesion between the upper made of natural leather or leather and the sole of shoes made of natural rubber or synthetic rubber is poor.

통상적으로 작업자가 신발 밑창의 바닥창의 상면에 일정량의 접착제를 도포한 후 육안으로 확인하면서 도포된 접착제의 위로 중창을 결합하게 된다. 이러한 작업은 물품자체에 요구되는 바닥창과 중창의 결합 정밀도가 저하되어 불량률이 매우 높을 뿐만 아니라 접착제 도포후 일정시간동안 큰 압력으로 눌러주어야 하므로 작업시간이 과다하게 소요되고 상기 결합작업에 의해 결합된 바닥창과 중창은 접착제에 의해 결합되기 때문에 호환성이 결여되는 문제가 있으며, 접착제는 수분에 취약하므로 결합부가 분리되는 문제점이 있다. 그리고 바닥창과 중창을 결합하기 위해서는 반드시 에폭시, 본드등의 접착제를 이용하여 접합되는데 이때 접착제에서 독성을 가진 냄새가 발산되어 작업자가 두통을 호소하거나 환각 또는 중독 증세를 일으키게되어 산업재해의 원인이 되고 있어 접착제를 이용하지 않고 바닥창과 중창을 결합하는 방법이 요구되고 있다.Typically, the operator applies a certain amount of adhesive to the upper surface of the sole of the shoe sole and then combines the midsole over the applied adhesive while visually checking. This work is not only very high defect rate due to the deterioration of the coupling precision of the sole and the midsole required for the article itself, but also because the pressure must be pressed at a large pressure for a certain period of time after the adhesive is applied, the work time is excessively consumed and the floor combined by the joining work. Since the window and the midsole are coupled by an adhesive, there is a problem in that the lack of compatibility, the adhesive is vulnerable to moisture, there is a problem that the bonding portion is separated. In order to combine the sole with the midsole, the adhesive must be bonded using epoxy, bond, etc. At this time, the toxic odor is emitted from the adhesive, which causes the worker to complain of headaches or hallucinations or addiction. There is a need for a method of joining soles and midsoles without the use of adhesives.

본 발명은 전술한 바와 같은 문제를 해결하기 위하여 안출한 것으로서, 여러가지 공정과 몰드로 제조되는 중창을 하나의 형틀에서 일체로 성형 제조하여 공정을 획기적으로 단축하고, 바닥창 또한 사출로 바로 제조할 수 있으며, 바닥창과 중창을 접착제 없이 결합할 수 있고, 갑피와 바닥창을 재봉으로 결합한후에 간단하게 중창을 결합시킬 수 있는 신발 밑창을 제공하고자 하는 목적을 가지고 있다.The present invention has been made in order to solve the problems described above, it is possible to significantly shorten the process by molding and manufacturing the midsole made of various processes and molds integrally in one mold, the sole can also be manufactured directly by injection In addition, the sole and the midsole can be combined without adhesive, and has the purpose to provide a shoe sole that can simply combine the midsole after sewing the upper and the outsole combined with sewing.
