Title: 우산식텐트의알루미늄골격
IPC: E04H15/28
Filed: 1999-03-25
Abstract: 가. 청구범위에 기재된 발명이 속하는 기술분야. 
     본 발명은 텐트의 골격이 우산식으로 절첩되면서 펴거나 접을 수 있도록 되는 텐트에 있어서, 특히 폴대가 알루미늄으로 성형되어지는 텐트에 관한 것으로 폴대의 중량을 경량화 하면서 탄력이 우수하고 또한 폴대에 의하여 텐트천의 손상을 방지토록 하기 위한 것이다. 
     나. 발명이 해결하려는 기술적 과제. 
     종래에 알루미늄으로 제조되어 우산 형식으로 들어올려 원터치로 펴거나 접을 수 있도록 구성된 텐트는 텐트의 골격을 이루는 휨폴대와 지지폴대가 원형 또는 타원형의 관이거나 또는 내부가 빈 사각기둥을 이용하고 있고, 휨폴대는 사방으로 연결될 수 있도록 끼임부가 직각으로 4등분되게 구분된 상부연결체에 절첩이 가능토록 직접 힌지 결합토록 하거나 또는 별도의 연결체를 이용하여 연결되고, 상기 상부연결체의 직하방으로는 결합관이 형성되고, 상부연결체의 끼임부에 사방으로 연결된 각각의 폴대 중간에는 지지대가 연결된 연결체가 연결되고 상기 지지대의 타측이 하부연결체의 끼임부에 끼워져 연결되고, 상기 하부연결체의 상부로는 결합돌축이 일체로 형성되어 있어, 텐트를 펼칠경우에 휨폴대의 하방으로 연결된 지지폴대가 지면에 고정된 상태에서 지지되어 진 상태에서 지지대가 연결되어진 하부연결체를 밀어올리면 지지대가 상부연결체에 연결된 휨폴대를 휘게 하면서 결합돌축이 상부연결체의 하부에 형성된 결합관으로 삽입되어져 지지대의 지지력과 폴대의 탄력에 의하여 텐트가 펼쳐지도록 되어 지는 것이고 펼쳐진 상태에서는 지지대의 지지력에 의한 휨폴대의 탄력과 지지폴대의 지지력에 의하여 고정되어지는 것이다. 
     그러나 이러한 방식의 텐트는 탄력지지되는 휨폴대가 원형의 관이나 사각기둥으로 이루어져 있기 때문에 휨강도가 강하여 유연하게 텐트를 펼칠 수 없는 단점이 있고, 또한 장시간 휨상태가 유지되어질 경우에는 휨폴대에 휨이 발생되는 문제점이 있고 이러한 휨폴대 또는 지지폴대가 접어진 상태에서 운반될 경우에 상.하부연결체와의 충돌로 인하여 텐트천에 손상을 발생시키게 되고 또한 연결체와 폴대를 연결하는 방식이 단순한 나사결합이거나 리벳결합이기 때문에 나사 또는 리벳의 풀림에 의한 연결부위의 빠짐이 발생되고, 또는 레벳의 선단에 형성되는 날카로움에 의하여 텐트천의 손상이 발생되는 문제점이 있는 것이었다. 
     다. 발명의 해결방법의 요지. 
     유연하고 강력한 탄력이 요구되는 상부연결체에 연결되는 휨폴대는 탄력이 우수한 사각체의 얇은 바를 이용하고 커다란 탄력이 요구되지 않고 지지력이 요구되는 하단 즉 지면에 위치되어지는 지지폴대는 원통관을 사용함으로서 골격의 유연성과 지지력을 향상시켰고, 이러한 휨폴대와 지지폴대가 접혀진 상태에서 상.하부연결체와 밀착되어지는 부위에는 탄성링을 형성하여 충격이 발생되지 않토록 하면서 폴대의 연결을 위한 나사나 리벳 결합 후에 돌출되는 선단을 가압연마에 의하여 둥근 머리를 형성하여 나사나 리벳이 탈리되지 못하도록 함으로서 종래의 문제점을 해결한 것이다.
