Description

Bicycle of assemble frame

본 발명은 자전거 프레임에 관한 것으로 상세하게는 자전거 프레임을 구성하는 톱튜브와 보텀튜브가 조립식으로 결합되는 자전거 조립식 프레임에 관한 것 이다.The present invention relates to a bicycle frame, and more particularly, to a bicycle prefabricated frame in which a top tube and a bottom tube constituting a bicycle frame are prefabricated.

본 발명은 자전거 프레임에 관한 것으로 상세하게는 자전거의 톱튜브와 보텀튜브가 인출로프의 인장력으로 고정되어 결합되는 자전거 조립식 프레임에 관한 것 이다.The present invention relates to a bicycle frame, and more particularly, to a bicycle assembly frame in which a top tube and a bottom tube of a bicycle are fixed and coupled by the tensile force of a pull-out rope.

일반적으로 자전거 프레임은 첨부도면 제24도에 예시된 바와같이 보텀브라켓쉘(3) 상측으로 입설되는 시트튜브(2) 전방으로 헤드튜브(1)가 배치되어 상기 시트튜브(2)와 헤드튜브(1)는 톱튜브(4) 및 보텀튜브(4a)에 의하여 상호 고정되게 결합되며, 또 한 상기 시트튜브(2) 후방으로 시트스테이(6) 및 상기 보텀브라켓쉘(3) 후방에 체인스테이(5)가 고정되게 결합 되어 자전거 프레임이 구성되는데 있어서,In general, as illustrated in the accompanying drawing 24, the head tube 1 is disposed in front of the seat tube 2 installed above the bottom bracket shell 3, so that the seat tube 2 and the head tube ( 1) is fixedly coupled to each other by a top tube (4) and a bottom tube (4a), and a chain stay (6) behind the seat tube (2) and a chain stay ( 5) is fixedly coupled to constitute a bicycle frame,

통상적으로 상기 헤드튜브(1)에 고정되게 결합되는 톱튜브(4) 및 보텀튜브(4a)의 선단부는 상기 헤드튜브(1) 원주 외주면에 밀착 되도록 만곡진 곡면부로 형성되어 상기 헤드튜브(1) 외주면에 밀착되게 배치된채, 용접수단을 통하여 상기 헤드튜브(1)와 한 몸체로 고정되게 결합되고, 또한 상기 톱튜브(4) 및 보텀튜브(4a)는 상기 시트튜브(2)와 보텀브라켓쉘(3)에 용접수단으로 고정되게 결합된다.In general, the tip ends of the top tube 4 and the bottom tube 4a that are fixedly coupled to the head tube 1 are formed as curved portions that are curved so as to be in close contact with the circumferential outer circumferential surface of the head tube 1, so that the head tube (1) While being disposed in close contact with the outer circumferential surface, the head tube 1 and the body are fixedly coupled to each other through welding means, and the top tube 4 and the bottom tube 4a are connected to the seat tube 2 and the bottom bracket. It is fixedly coupled to the shell 3 by welding means.

이러한 톱튜브(4) 및 보텀튜브(4a)가 상기 헤드튜브(1)를 포함하여 시트튜브(2) 및 보텀브라켓쉘(3)에 용접수단으로 고정되게 결합되는 과정에 용접열에 의한 열변형이 동반되어 별도의 전문제작기구(툴)가 있어야 하며, 또한 용접열에 따른 프레임 튜브의 고유 열처리 특성이 감소되어 프레임 접합부 강도 저하에 따른 자전거 프레임이 파손되는 자전거 프레임의 안전성 문제가 야기되었다.During the process in which the top tube 4 and the bottom tube 4a are fixedly coupled to the seat tube 2 and the bottom bracket shell 3, including the head tube 1, by welding means, thermal deformation due to welding heat occurs. A separate specialized manufacturing tool (tool) was required to accompany it, and the inherent heat treatment characteristics of the frame tube were reduced due to the heat of welding, which caused a safety problem in the bicycle frame in which the bicycle frame was damaged due to the decrease in the strength of the frame joint.

이러한 자전거 프레임의 안정성 문제와; 자전거 프레임의 더 가벼운 프레임을 개선 하고자 자전거 톱튜브(4) 및 보텀튜브(4a)의 양단부에 구성되는 튜브의 두께는 다소 두껍게 형성되는 반면에 튜브 중앙부의 두께가 더 얇게 형성되는 버티드 튜브를 개발하여 좀 더 가벼운 자전거 프레임을 제작하고 있으나, 이러한 버티드 튜브는 생산공정이 더 복잡하여 자전거 프레임의 제작 단가가 높으며, 무엇보다 상기 버티트 튜브는 두께가 얇아서 반복적인 외부충격 흡수가 부족하여 튜브의 피로누적이 심하며, 이에 따라 자전거 프레임의 내구성 저하 및 외부충격 흡수율 저하에 따른 자전거 승차감이 저하되는 문제가 있었다.with the stability issues of these bicycle frames; In order to improve the lighter frame of the bicycle frame, the tube formed at both ends of the bicycle top tube (4) and the bottom tube (4a) is slightly thicker, while the butted tube is formed to be thinner in the center of the tube. Thus, a lighter bicycle frame is being manufactured, but the production process of these butted tubes is more complicated, so the production cost of the bicycle frame is high. Above all, the butt tube is thin and lacks repeated external shock absorption, so the tube There was a problem in that the fatigue accumulation was severe, and thus, the riding comfort of the bicycle was deteriorated due to the deterioration of the durability of the bicycle frame and the reduction of the external shock absorption rate.

이러한 자전거 프레임의 안전성 문제와 더 가벼운 자전거 프레임을 개선 하고자 하는 다른 수단으로는 최근에는 카본소재를 이용한 더 가볍고, 충격흡수가 개선되는 자전거 카본 프레임이 널리 사용되고 있으나, 자전거 카본 프레임은 카본소재를 이용한 일체형의 가압 성형품으로 제작되어 제작과정이 매우 복잡하여 제작 단가가 높은 단점이 있고, 자전거 프레임 부분 파손시 수리 복구가 곤란한 문제가 있었다.As another means to improve the safety problem of the bicycle frame and the lighter bicycle frame, a bicycle carbon frame that is lighter and has improved shock absorption using carbon material is widely used in recent years. However, the bicycle carbon frame is an integral type using carbon material. Since it is manufactured as a press-molded product of , the manufacturing process is very complicated, so the manufacturing cost is high, and there is a problem that repair and recovery is difficult when the bicycle frame part is damaged.

또한 대부분 자전거 프레임 각각의 접합부는 고정방식 일체형으로 구성되어 자전거 프레임 각 구성 요소들을 한 몸체로 일체화 하는 제작 작업은 자전거 프레임의 전문제작소 및 전문기술을 필요로 하게 되며, 또한 필요시 자전거 운송과정에 자전거 프레임의 분리 및 조립이 곤란한 문제가 있다.In addition, most of the junctions of each bicycle frame are composed of a fixed type, so the production work to integrate each component of the bicycle frame into one body requires a specialized manufacturing shop and specialized technology for the bicycle frame. Also, if necessary, the bicycle can be transported in the process of transporting the bicycle. There is a problem in that it is difficult to separate and assemble the frame.
