Abstract: 가. 청구범위에 기재된 발명이 속하는 기술분야. 
     본 발명은 폴대가 일체로 형성된 텐트가 우산식으로 원터치로 펼쳐질 수 있도록 되는 텐트에 있어서, 폴대를 사방으로 연결하는 연결체가 적당한 각도로 임의대로 조절될 수 있도록 되어 텐트를 정사각형이나 직사각형으로 임의대로 펼쳐질 수 있도록 되는 텐트에 관한 것이다. 
     나. 발명이 해결하려는 기술적 과제. 
     종래에 우산 형식으로 들어올려 원터치로 펴거나 접을 수 있도록 텐트는 폴대가 사방으로 연결될 수 있도록 직각으로 4등분되게 구분된 상부연결체를 사용하여 상부연결체의 하단에는 절첩되어질 수 있도록 관이 안테나 식으로 연결되어지고, 상부연결체에 사방으로 연결된 각각의 폴대에는 지지대가 하부연결체와 사방으로 연결되고 하부연결체의 상부로는 결합돌축이 형성되어 있어, 텐트를 펼칠경우에 지지대가 연결되어진 하부연결체를 밀어올리면 결합돌기가 상부연결체의 하부에 형성된 관으로 삽입되면서 지지대의 탄력에 의하여 폴대가 펼쳐지면서 텐트가 펼쳐지도록 결합토록 되어 지는 것이다. 
     그러나 이러한 방식의 텐트는 연결체가 직각으로 정확하게 4등분으로 구분되어 있기 때문에 텐트가 정형된 형태로판 펼칠 수 있게 되어 텐트를 칠 공간이 적당치 아니할 경우에는 텐트를 치지 못하게 되는 단점과 또한 텐트를 쳤을 경우에도 바람이나 외력에 의하여 폴대에 압력이 전단될 경우에 폴대가 연결체에 고정되어 있기 때문에 텐트가 쓰러지지 않을 경우에는 폴대가 휘어지거나 부러지게 되는 등의 문제점이 있는 것이 었다. 
     다. 발명의 해결방법의 요지. 
     연결체를 일정한 각도로 회전이 자유롭게 함으로서 텐트를 사각형이나 직사각형으로 원하는 형태로 텐트를 칠 수 있도록 함으로서 종래의 문제점을 해결한 것이다.
