본 고안은 사닥다리에 관한 것으로서, 특징은 사닥다리의 지지바와 발디딤바를 매우 합리적인 구조로 서로 견고한 고정상태로 유지시킬수 있도록 하여 사닥다리를 오를때 지지바와 발디딤바가 서로 이완되어 흔들거림을 방지할 수 있도록 하므로서 작업자에게 안정감을 줄 수 있도록 한데 있다.The present invention relates to a ladder, the feature is that the support bar and the foot tread bar of the ladder is very reasonable structure to keep each other firmly fixed so that the support bar and the foot tread bar to relax each other when climbing the ladder to prevent shaking It is put together to give a sense of stability.

종래의 사닥다리는 지지바에 구멍을 뚫어서 이의 구멍에 발디딤바의 양단부를 끼워 용접하여 고정시키거나 지지바의 평면돌편에 부라켓판을 개재시켜 발디딤바를 고정시켜서 된 것으로 대별할 수 있다 하겠는데 전자는 지지바에 구멍을 뚫어서 이의 구멍에 발디딤바의 양단을 끼워 용접하여 고정시키게 되므로 결합 견고성은 매우 양호하다 하겠으나 그러나 일일이 인력으로 용접하여 고정시키게 되므로 시간과 인력을 많이 요하게 되어 대량생산에 있어 어려움이 따르게 되면서 용접 후 용접부의 도장작업에 많은 난점이 따르게 되어 도장작업을 생략하게 되므로 미관이 양호하지 못한 결저이 있었다.Conventional ladders can be classified as either by drilling a hole in the support bar and fixing it by inserting both ends of the foot dim bar into the hole thereof and fixing the foot dim bar by interposing a bracket plate on the flat stone of the support bar. The joint firmness is very good because it will be fixed by welding the hole by inserting both ends of the foot dimbar into the hole. However, since it is fixed by welding one by one, it requires a lot of time and manpower. There were many difficulties in the painting work of the weld, so that the painting work was omitted, so that the appearance was not good.

또한 후자는 지지바의 돌편에 부라켓판을 개재시켜 발디디판을 나사못을 고정시키게 되므로 작업은 비교적 용이하다 하겠으나 지지바와 부라켓판 및 발디딤판이 서로 평면으로 접촉 조정케 되므로 결합 상태가 견고하지 못하고 용이하게 흔들거리게 되어 사닥다리에 서서 작업시 작업자에게 불안감을 주게 될 뿐만 아니라 고정부가 쉬 손상케 되어 비교적 사용수명이 짧은 결점이 있었다.In addition, the latter is a relatively easy operation because the foot pad is fixed to the screws of the support bar by interposing a bracket plate, but the support bar, the bracket plate and the foot plate are in contact with each other in a plane to adjust the connection state is not firm It was easily shaken, not only to give anxiety to the worker when standing on the ladder but also to damage the fixing part easily, which resulted in a relatively short service life.

본 고안은 상기와 같은 결점을 해소시킬 수 있도록 한 매우 합리적인 구조로 구성한 사닥다리를 안출하게 된 것인데 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to devise a ladder consisting of a very reasonable structure to solve the above drawbacks described in detail by the accompanying drawings as follows.

양 지지바(1)에 일정한 간격으로 부라켓판(3)을 개재시켜 발디딤바(2)를 나사못(4)으로 고정시켜서 된 사닥다리에 있어서, 지지바(1)에 돌출된 돌편에는 요입홈조(101)(102)를 형성하고 부라켓판(3)에는 돌조(301)(302)를 돌출하여 돌조(301)(302)를 요입 홈조(101)(102)에 끼워서 나사못(4)으로 고정시켜서 된 것이다.In the ladder, which is fixed to the support bar (1) with a foot bracket plate (3) at regular intervals on both support bars (1) with a screw (4), protruding grooves ( 101 and 102 are formed, and the buckle plate 3 protrudes the protrusions 301 and 302 so that the protrusions 301 and 302 are inserted into the recessed grooves 101 and 102 and fixed with screws 4. It is.

이와 같이 된 본 고안은 일측을 발디딤바(2)와 나사못(4)으로 고정시킨 부라켓판(3)에 돌출된 돌조(301)(302)를 양 지지바(1)에 요입된 요입홈조(101)(102)에 끼우게 되면 사닥다리에 고정시키고자 하는 폭으로 저절로 맞추어 지게 되므로 나사못(4)으로 고정시켜 제조하기가 매우 용이하여 개당 제조에 인력과 시간을 많이 요하지 않게 되어 생산비가 싸게 먹히면서도 대량생산이 가능하고 또한 사닥다리는 안정을 고려하여 윗쪽으로 갈수록 폭이 좁게 구성되고, 본원은 부라켓판(3)의 돌기(301)(302)는 지지바(1)의 요입홈조(101)(102)에 끼워진 상태이므로 발디딤바(2)에 무게가 가해질 때 무게에 의하여 발디딤바(2)가 제 1 도의 화살표방향으로 미세하게 하향 이동 하면 할수록 부라켓판(3)의 돌기(301)(302)는 더욱 지지바(1)의 요입홈조(101) (102)면에 압접케 되므로 지지바(1)와 발디딤바(2)는 서로 더욱 견고한 상태로 된다.The present invention, as described above, the grooves indented into both support bars 1, the protrusions 301 and 302 protruding from the racket plate 3, the one side of which is fixed with the foot pad 2 and the screw 4. 101) (102) is fitted to the width of the ladder to be fixed on its own, so it is easy to manufacture by fixing with a screw (4) is very easy to manufacture, it does not require a lot of manpower and time to manufacture each production cost It is possible to mass-produce and the ladder is configured to have a narrower width toward the upper side in consideration of the stability, and the projections 301 and 302 of the racket plate 3 are recessed grooves 101 of the support bar 1 ( 102, the protrusions 301 and 302 of the racket plate 3 are moved more and more downward in the direction of the arrow of FIG. 1 by the weight when the weight is applied to the foot tread bar 2. ) Is further pressed into the groove groove 101, 102 surface of the support bar (1) 1 and the footing bar (2) is a more robust with each other.

이와 같은 본 고안은 간단하고 매우 합리적인 구조로 구성되었으므로 저렴한 생산비로 대량생산이 가능할 뿐만 아니라 사용에 있어 견고한 고정력으로 흔들림을 방지하여 작업자가 불안한 감이 없이 안전한 마음으로 작업을 행할 수 있는 효과가 있다.Since the present invention is made of a simple and very reasonable structure, it is possible to mass production at a low production cost, as well as to prevent shaking by using a solid fastening force in use, there is an effect that the operator can work safely without feeling anxious.
