Description

절첩식 사다리용 고정버튼Fixed button for folding ladder

절첩식 사다리는 사람의 손이 닿지 못하는 높은 곳에서 작업할 때 작업자의 받침대로 사용되고 있다. 더욱이 사다리의 높이를 연장하기 위해서는 기초부인 외부사다리에 내부 사다리를 이동가능하게 삽입하여 원하는 높이에서 외부사다리와 내부사다리를 고정하여 사용한다. 그런데 이러한 절첩식 사다리의 외부사다리와 내부사다리를 고정하는 고정기구는 견고하게 고정되지 않으면 작업자가 사다리위에 있을 때 불의로 접혀서 사고의 위험이 있으며 고정하는 방법이 간편해야 사용하기에 불편함이 없다.Folding ladders are used as an operator's support when working in high places, out of reach of humans. Furthermore, in order to extend the height of the ladder, the internal ladder is inserted into the external ladder as a base so as to be movable, and the external ladder and the internal ladder are fixed at a desired height. By the way, the fixing mechanism for fixing the external ladder and the internal ladder of the folding ladder is unintentionally folded when the operator is on the ladder, there is a risk of accidents and there is no inconvenience to use when the fixing method is simple.

본 고안의 목적은 상기와 같은 요구에 부응하여 내부사다리를 원하는 위치로 빼낸 후 외부사다리와 견고하게 고정시킬 수 있도록 고정버튼에 고정캡을 연결하고 고정캡을 안내하는 안내부를 외부사다리의 측벽에 설치하며 스프링이 고정캡과 안내부사이에 설치되어 고정캡은 안내부로부터 외부사다리의 내부로 돌출되게 밀쳐지고 고정캡의 원주에는 체결홈이 형성되고 안내부에는 체결돌기가 형성되어 이들의 상호체결에 의하여 고정버튼이 회전되면 고정캡이 외부사다리의 관통홈으로부터 잠정적으로 빠져나와 내부사다리가 외부사다리속에서 이동가능하고 이동이 완료되면 고정버튼을 반대로 회전시켜 고정캡이 내부사다리의 내부사다리의 발판홈에 고정되게 구성된 절첩사다리용 고정버튼을 제공하고자 하는 것이다.The purpose of the present invention is to meet the requirements as described above, after removing the internal ladder to the desired position to connect the fixing cap to the fixed button so that it can be fixed firmly with the external ladder and to install the guide portion for guiding the fixing cap on the side wall of the external ladder The spring is installed between the fixing cap and the guide part, and the fixing cap is pushed to protrude from the guide part to the inside of the external ladder, and a fastening groove is formed at the circumference of the fixing cap, and a fastening protrusion is formed at the guide part, thereby When the fixing button is rotated, the fixing cap temporarily moves out of the through ladder of the external ladder, and the internal ladder can move inside the external ladder. It is to provide a fixed button for folding ladder configured to be fixed.
