Description

휴대 자전거Mobile bicycle
본 발명의 실시예는 휴대 자전거에 관한 것이다.An embodiment of the present invention relates to a portable bicycle.
일반적으로 사용자의 답압력을 이용하여 전륜이나 후륜을 구동시킴으로써 화물을 운반하거나 이동수단으로서의 기능을 수행하는 자전거는 인력을 이용한 대표적인 교통수단의 하나로서 널리 사용되어 왔으며, 특히 최근에는 운동기구로서의 건강증진효과와 함께 레크레이션 수단으로서의 다양한 응용이 가능한 한편, 환경친화적인 특성에 의해 수요가 점차 확산되고 있다.In general, bicycles that carry cargo or perform functions as a means of transportation by driving the front wheels or the rear wheels using the user's response pressure have been widely used as one of the representative means of transportation using manpower. Along with the effects, various applications as recreational means are possible, while demand is gradually spreading due to environmentally friendly characteristics.
이와 같은 자전거는 통상적으로 프레임, 포크, 안장 및 핸들 등으로 구성되는 지지부분과, 크랭크 및 패달 등으로 구성되는 동력접수부분 및 체인 및 스프라켓과 변속장치 등으로 구성되는 전동부분으로 구성된다.Such a bicycle is typically composed of a support portion composed of a frame, a fork, a saddle and a handle, a power receiving portion composed of a crank and a pedal, and an electric portion composed of a chain, a sprocket, a transmission, and the like.
한편, 상기한 바와 같은 통상적인 구조의 자전거는 트러스 구조의 다아몬드형 프레임을 구조체로 사용함으로써 사용자의 신장에 비례하여 고중량과 함께 대형의 크기를 갖게 되는데, 이와 같은 대형의 프레임을 구조체로 사용한 자전거는 우수한 주행특성과 기계적 특성을 갖는 반면, 넓은 점유공간을 필요로 한다.On the other hand, the bicycle of the conventional structure as described above has a large size with a heavy weight in proportion to the height of the user by using the truss-shaped diamond-shaped frame as a structure, the bicycle using such a large frame as a structure While having excellent running and mechanical properties, it requires a large occupied space.
따라서, 트러스 구조를 갖는 다이아몬드형 프레임을 채용한 자전거는 주행과정에서 안정적인 특성을 보장하는 반면, 미사용시에는 넓은 점유공간을 필요로 함으로써 엘리베이터를 통한 이동이나 실내보관이 어렵하고, 주행과정에서 버스나 지하철과 같은 대중교통의 이용을 병행하는 윤행이 곤란하며, 승용차를 통한 적재시에는 별도의 고정수단이 필요하다는 등의 문제점이 따른다.Therefore, the bicycle adopting the truss-shaped diamond frame ensures stable characteristics during the driving process, while when not in use, it requires a large occupied space, making it difficult to move through the elevator or to store the room. It is difficult to travel in parallel with the use of public transportation such as subways, and when loading through a passenger car, a separate fixing means is required.
이에 따라 근래에 개발된 자전거는 프레임과 같이 많은 공간을 차지하는 부품을 절첩가능하게 구성함으로써 실내보관이 원활히 이루어지도록 하는 한편, 이동 및 운반과정에서 필수공간을 최소화하도록 한다.Accordingly, recently developed bicycles are configured to be able to fold up components that occupy a large amount of space such as a frame so that indoor storage can be made smoothly while minimizing essential spaces in the process of transportation and transportation.
