Description

금속의 내답판이 일체로 성형된 안전화용 깔창과 그 제조방법Safety shoe insole integrally formed with an inner plate of metal and its manufacturing method

본 발명은 안전화에 관한 것으로서 안전화용 아웃솔과 내피사이에 설치되는 철판을 아웃솔 자체에 내장되게 하므로써 안전화의 제조공정을 줄이므로써 작업시간을 단축하고 단시간에 대량의 물품을 생산할 수 있도록 하는데 그 목적이 있는 것이다.The present invention relates to safety shoes by reducing the manufacturing process of the safety shoes by allowing the iron plate installed between the safety shoes outsole and the inner shell to be embedded in the outsole itself to shorten the working time and to produce a large amount of goods in a short time. It is.

일반적으로 건축분야에서 안전을 위하여 사용하는 안전화와 등산을 위한 등산화에는 발을 보호하기 위하여 신발의 바닥면에 철판이 내장되어 있는 바, 종래에 사용되어 온 안전화는 안전화의 부품중 바닥창과 내답판을 별도로 제작하여 제조공정에서 접착제로 접착하여 구성하였다.In general, the safety shoes used for safety in the construction field and hiking boots for climbing have iron plates embedded in the soles of the shoes to protect the feet. It was manufactured separately and bonded with an adhesive in the manufacturing process.

즉 종래의 방법은 바닥창과 내답판을 별도로 각각 제조하고, 이 상태에서 가죽을 이용하여 안전화를 구성한 다음 안전화의 코부분에 중량물로부터 발가락을 보호하는 캡을 씌운 다음 그 외부에 다시 가죽을 덮어 안전화를 구성한 다음 못으로부터 발을 보호하는 내답판에 접착제를 도포하여 안전화의 바닥면 외부에 부착하고, 다시 내답판과 안전화의 바닥면에 접착제를 도포한 다음 깔창을 접착하여 고정하였다.In other words, in the conventional method, the sole and the inner board are separately manufactured, and in this state, the safety shoes are constructed using leather, and the nose portion of the safety shoes is covered with a cap to protect the toes from heavy materials, and then the leather is covered with the outside again. After the construction, the adhesive was applied to the inner board to protect the foot from the nail and attached to the outside of the bottom of the safety shoes.

그러나 상기의 방법은 안전화의 바닥면에 내답판을 부착하기 위하여 안전화와 내답판에 접착제를 도포한 다음 약간 건조시킨 상태에서 내답판을 접착한 다음, 다시 내답판이 접착된 부분과 안전화의 아웃솔에 접착제를 도포한 상태에서 아웃솔을 접착 고정하였기 때문에 작업이 복잡하고 힘들며 접착제 도포시 접착제가 손에 묻어 작업이 번거롭고 이로 인하여 작업시간이 오래 걸리는 문제점이 있었다.However, in the above method, in order to attach the inner board to the bottom of the safety shoes, an adhesive is applied to the safety shoes and the inner board, and then the inner board is glued in a slightly dry state, and then the adhesive is attached to the portion of the inner board and the outsole of the safety shoes Since the outsole is adhesively fixed in the coated state, the work is complicated and difficult, and when the adhesive is applied, the adhesive is buried in the hand and the work is cumbersome, and thus the work takes a long time.

또한 상기와 같은 방법은 중창과 깔창 사이에 내답판이 접착되어 있기 때문에 안전화를 신고 보행을 할 경우 안전화의 중간부분이 접히게 되므로서 중창과 깔창 사이에서 접착되어 있던 부분이 떨어지게 되는 단점이 있으며, 또한 내답판이 중창과 깔창 사이에서 유동되므로 깔창과 중창사이에서 유동되어 접착부분을 분리하게 되므로서 안전화의 수명을 단축시키게 되는 큰 문제점이 있었다.In addition, the above method has a disadvantage in that the inner part of the safety shoes are folded between the midsole and the insole, so the inner part is bonded between the midsole and the insole. Since the inner plate flows between the midsole and the insole, there is a big problem that the life span of the safety shoes is shortened by being separated between the insole and the midsole to separate the adhesive portion.

한편 종래에는 내답판과 깔창등의 각각 부품을 직접 접착하여야하기 때문에 작업 공정이 복잡하고 안전화의 바닥면에 금속으로 된 내답판을 접착하기가 힘들어 불량이 많이 발생하는 단점이 있으며, 이로 인하여 작업시간이 오래 걸리므로서 불필요한 인건비를 지출하게 되는 문제점이 있었다.On the other hand, in the prior art, since each part of the inner board and insole have to be directly bonded, the work process is complicated, and it is difficult to adhere the metal inner board to the bottom of the safety shoes, which causes a lot of defects. As this takes a long time there was a problem of spending unnecessary labor costs.

또한 종래에는 단단하고 발바닥형상의 굴곡을 이룬 판재로된 중창이 갑피를 고정하여 신발의 형태를 유지하였기 때문에 발바닥형상으로 이루고 있는 중창과 평판으로 된 내답판으로 인하여 접착이 힘들고 어려우며, 이로 인하여 불량률이 대단히 높아 원자재를 낭비하게 되므로서 불필요한 지출을 초래하였으며, 이로 인하여 내답판을 접착하기 위하여 고액의 숙련공을 요하게 되어 불필요한 인건비를 지출하게 되므로서 제작단가를 상승시키게 되는 문제점이 있었다.In addition, in the past, since the midsole made of a solid sole of the sole of the sole of the sole is fixed to the upper to maintain the shape of the shoe, it is difficult and difficult to adhere due to the sole of the sole of the sole and the inner plate of the flat plate. Very high wasted raw materials to waste unnecessary, and this requires a large amount of skilled workers to bond the inner plate, there is a problem that the cost of production is increased because unnecessary labor costs.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 안전화용 깔창(아웃솔)의 중간부에 내답판이 삽입되게 일체로 제작하여서 된 것으로서, 간단하게 깔창만 부착하면 안전화가 조립되도록 한 것으로서, 이하 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in order to solve the above problems, it is made by integrally inserting the inner plate to the middle portion of the safety shoe insole (outsole), simply attached to the insole to be assembled safety shoes, as follows The present invention will be described in detail with reference to the accompanying drawings.

상기와 같이 구성된 본 발명의 제조방법을 설명하면 다음과 같다.Referring to the manufacturing method of the present invention configured as described above are as follows.

상부금형(2)을 연 다음 상부금형(2)의 저면에 돌출되어 있는 영구자석(4)에 내답판(3)의 양측에 형성되어 있는 고정공(8)에 체결하여 고정한다. 이때 내답판(3)의 고정공(8)에 삽입 체결되어 있는 상태에서 영구자석(2)이 내답판(3)을 고정하고 있기 때문에 내답판(3)이 좌, 우로 유동되는 것을 방지하게 된다.The upper mold 2 is opened and then fastened to the permanent magnets 4 protruding from the bottom surface of the upper mold 2 to the fixing holes 8 formed at both sides of the inner plate 3. At this time, since the permanent magnet 2 fixes the inner plate 3 while being inserted into the fixing hole 8 of the inner plate 3, the inner plate 3 is prevented from flowing left and right. .

상기와 같은 상태에서 하부금형(6)에 수지를 주입한 다음 상부금형(2)을 닫으면 하부금형(6)에 투입되어 있던 수지(7)가 발포하게 되고, 이로 인하여 수지(7)가 내답판(3)의 상부로 발포되므로서 내답판(3)이 깔창(1)의 중간부분에 위치하게 되는 것이다.When the resin is injected into the lower mold 6 and the upper mold 2 is closed in the above state, the resin 7 injected into the lower mold 6 is foamed, and thus the resin 7 is the inner board. The inner board 3 is positioned in the middle of the insole 1 as it is foamed to the upper portion of (3).

한편 내답판(3)에 형성되어 있는 수개의 관통공(4)을 통하여 상, 하부로 수지(7)가 발포되어 일체를 이루기 때문에 안전화를 신고 보행을 할 경우 내답판(3)이 깔창(1)의 내부에서 유동되지 못하게 됨으로서 내답판(3)으로 인한 안전화의 불량을 방지할 수가 있는 것이다.On the other hand, since the resin 7 is foamed up and down through several through-holes 4 formed in the inner board 3 to form a unit, the inner board 3 is insole when walking in safety shoes. By not being able to flow in the interior of the) it is possible to prevent the failure of the safety shoes due to the inner plate (3).

또한 내답판(3)이 깔창(1)의 중간부에 삽입된 상태에서 깔창(1)이 제조되기 때문에 안전화의 외부에 단순히 깔창만을 접착하면 되므로 제조공정을 줄일 수가 있으며, 이로 인하여 제작시간을 단축할 수가 있는 것이다.In addition, since the insole 1 is manufactured in the state where the inner plate 3 is inserted in the middle portion of the insole 1, the insole 1 is simply attached to the outside of the safety shoes, thereby reducing the manufacturing process, thereby shortening the manufacturing time. You can do it.

이상과 같이 본 발명은 안전화용 깔창(아웃솔)의 중간부에 내답판을 삽입시켜 일체로 제작하여서 된 것으로서, 제조공법이 간단하여 손쉽게 제작할 수 가 있으며 제조공정을 줄이므로서 작업시간을 단축하고 내답판이 깔창에 일체로 내장되어 있기 때문에 내답판으로 인한 불량을 방지할 수가 있으며, 이로 인하여 누구 나가 간단하게 안전화를 조립할 수가 있으므로써 단시간에 대량의 안전화를 제작할 수가 있는 유용한 발명인 것이다.As described above, the present invention is made by integrally inserting the inner plate in the middle of the safety shoe insole (outsole), and the manufacturing method is simple and easy to manufacture, and shortens the working time while reducing the manufacturing process. Since the plate is integrally built into the insole, it is possible to prevent defects due to the inner plate, which is a useful invention that anyone can easily assemble the safety shoes in a short time to produce a large amount of safety shoes.
