Zusammenfassung: | The present invention relates to a bicycle frame. More particularly, the present invention relates to a prefabricated bicycle frame in which main components constituting the bicycle frame are prefabricated. In the prefabricated bicycle frame, a right female screw is formed on a front end coupling member configured at one end of a top tube, and a left female screw is formed on a rear end coupling member configured at the other end of the top tube. In a first coupling means configured in a head tube, a head coupling body having a right male screw is configured and coupled to the front end coupling member. In a seat fixing member coupled to a seat tube, a seat coupling body having a left male screw is configured to be coupled to the rear end coupling member, and when the top tube is rotated, the head tube and seat tube are coupled to the top tube in a turnbuckle method. A second front end coupling member configured at one end of a bottom tube is formed with a right female screw, and a second rear end coupling member configured at the other end of the bottom tube is formed with a left female screw. In a second coupling means configured in the head tube, a second head coupling body having a right male screw is formed and coupled to the second front end coupling member. In addition, in a curved surface coupling means provided on a bottom bracket shell, a first fixing member having a left male screw is configured to be coupled to the second rear end coupling member, and when the bottom tube is rotated, the head tube and the bottom bracket shell are combined with the bottom tube in a turnbuckle method.
본 발명은 자전거 프레임에 관한 것으로 상세하게는 자전거 프레임을 구성하는 주요 구성요소가 조립식으로 결합되는 자전거 조립식 프레임에 관한 것이다. 자전거 프레임에 있어서, 톱튜브 일단부에 구성된 선단결합부재에는 오른쪽 암나사가 형성되며, 톱튜브 타단부에 구성된 후단결합부재에는 왼쪽 암나사가 형성되는 것과; 헤드튜브에 구성된 제1 결합수단에는; 오른쪽 숫나사가 형성된 헤드결합체가 구성되어 상기 선단결합부재와 결합되며, 시트튜브에 결합된 시트고정부재에는; 왼쪽 숫나사가 형성된 시트결합체가 구성되어 상기 후단결합부재와 결합되는 특징으로 톱튜브를 회전하면, 턴버클방식으로 헤드튜브와 시트튜브가 톱튜브에 결합되는 것과; 보텀튜브 일단부에 구성된 제2 선단결합부재는 오른쪽 암나사가 형성되며, 보텀튜브 타단부에 구성된 제2 후단결합부재는 왼쪽 암나사가 형성되는 것과; 헤드튜브에 구성된 제2 결합수단에는; 오른쪽 숫나사가 형성된 제2 헤드결합체가 구성되어 상기 제2 선단결합부재와 결합되며, 또한 보텀브라켓쉘에 제공되는 곡면결합수단에는; 왼쪽 숫나사가 형성된 제1 고정부재가 구성되어 상기 제2 후단결합부재와 결합되는 특징으로 보텀튜브를 회전하게 되면, 턴버클방식으로 헤드튜브와 보텀브라켓쉘이 보텀튜브에 결합되는 특징을 갖는 자전거 조립식 프레임. |
