본 발명은 관절형 연결장치에 관한 것이다.The present invention relates to an articulated connector.

일반적으로 컨테이너란 철판으로 형성된 큰 상자 형태로서, 트럭이나 선박을 이용하여 화물 수송에 주로 쓰이는 것을 말한다. 이와 같은 컨테이너는 일정 규격을 갖춘 크기로 이루어져 운송이 쉬울 뿐만 아니라, 내부 공간에 적재되어 있는 화물을 보호할 수 있는 장점이 있다.In general, a container is a large box made of steel plates and is mainly used for cargo transportation using trucks or ships. Such containers are not only easy to transport because they are sized to meet certain standards, but also have the advantage of protecting cargo loaded in the internal space.

이와 같은 컨테이너는 전용으로 사용되는 큰 화물차량에 의해 낱개로 운송되거나 전용 열차 또는 전용 선박에 의해 다량으로 운송되고 있다. 하지만, 컨테이너는 화물을 실어서 일정 지역으로 운송한 후에는 다시 출발지로 돌아와야 하는데 이때 빈 컨테이너 상태로 돌아오게 될 경우 무게는 가벼운데 컨테이너 자체는 똑같은 적재 공간을 차지하게 되어 물류비용 측면에서 막대한 손실이 발생된다.Such containers are transported individually by large cargo vehicles for exclusive use or in large quantities by dedicated trains or ships. However, after loading the cargo and transporting it to a certain area, the container must return to the departure point. If it returns as an empty container, the weight is light, but the container itself occupies the same loading space, resulting in a huge loss in terms of logistics costs. occurs.

또한, 항만에서 선박을 이용하여 운송할 경우 컨테이너를 다층으로 적재하여 운송하는데 빈 컨테이너도 화물이 적재된 컨테이너와 같이 적층하여 운송하게 되어 선박의 수용공간을 많이 차지되므로 운송비가 상승된다.In addition, when transporting containers at a port using a ship, containers are transported by stacking them in multiple layers. Empty containers are also transported in a stack along with containers loaded with cargo, which takes up a lot of space on the ship and increases transport costs.

이러한 문제를 해결하기 위해 빈 컨테이너를 운반하는 경우에는 컨테이너를 접어서 부피를 줄인 수 있는 기술들이 개발되고 있다.To solve this problem, technologies are being developed to reduce the volume of containers by folding them when transporting empty containers.
