Description

작은 바퀴 자전거{a bicycle}Small wheel bicycle {a bicycle}

본 발명은 작은 바퀴 자전거에 관한 것으로서, 더욱 상세하게는 두 개의 뒷바퀴에는 동력이 동시에 전달되고, 두 개의 앞바퀴는 동시에 조향이 이루어져 부드러운 주행이 이루어지면서도, 간편하게 접으면 부피가 작게되어 휴대 및 보관이 간편하게 이루어질 수 있도록 발명에 관한 것이다.The present invention relates to a small wheel bicycle, more specifically, the power is transmitted to the two rear wheels at the same time, the two front wheels at the same time the steering is made at the same time, while smooth running, easy to fold the volume is reduced to carry and storage It relates to the invention to be made easily.

일반적으로 자전거는 사람의 힘으로 바퀴를 회전시켜 움직이는 2륜차로 발로 밟아 힘을 내는 페달, 크랭크 기구, 체인을 거쳐 뒷바퀴에 동력이 전달될 수 있도록 구성되어 있다.In general, bicycles are configured to transmit power to the rear wheels through pedals, crank mechanisms, and chains that are stepped on a two-wheeled vehicle that rotates the wheels by human force.

현대에는 바퀴가 작은 자전거들이 개발되어 있고, 접으면 부피가 최소화되어 간편하게 휴대 및 보관할 수 있는 자전거가 개발되어 있다.In modern times, bicycles with small wheels have been developed, and bicycles have been developed that can be easily carried and stored with minimal volume when folded.

그러나, 바퀴가 작은 경우에는 큰 바퀴에 비하여 체중에 의한 하중 때문에 노면에 의한 상당한 마찰을 발생시킴에 따라 주행속도가 느려지고 승차감이 나빠지는 등의 폐단이 발생되었다.However, when the wheels are small, a significant friction caused by the road surface due to the weight due to the weight due to the weight of the large wheels, the running speed is slowed and the riding comfort is worsened.

본 발명은 상기한 문제점을 감안하여 창안한 것으로서, 그 목적은 두 개의 뒷바퀴에는 동력이 동시에 전달되고, 두 개의 앞바퀴는 동시에 조향이 이루어져 부드러운 주행이 이루어지면서도, 간편하게 접으면 부피가 작게되어 휴대 및 보관이 간편하게 이루어질 수 있는 작은 바퀴 자전거를 제공함에 있는 것이다.The present invention has been made in view of the above problems, the object of which is to transmit power to the two rear wheels at the same time, the two front wheels are made by steering at the same time to achieve a smooth running, easy to fold the volume is small and portable It is to provide a small wheel bike that can be easily stored.

상기한 목적을 달성하기 위한 본 발명의 특징은, 프레임(10)에 핸들(11), 페달(12), 스프로킷(13), 체인(14), 앞바퀴(20), 뒷바퀴(30)들이 결합된 작은 바퀴 자전거(1)에 있어서, 상기 뒷바퀴(30)에는 보조 뒷바퀴(31)가 스프로킷(13), 체인(14) 및 체인(31a)으로 연결되어 함께 구동되고, 앞바퀴(20)에는 보조 앞바퀴(21)가 장착되어 핸들(11)을 회전시키면 체인(21a)으로 연결되어 동시에 조향이 이루어질 수 있도록 한 것을 특징으로 하는 작은 바퀴 자전거에 의하여 달성될 수 있는 것이다.Features of the present invention for achieving the above object, the handle 10, the pedal 12, the sprocket 13, the chain 14, the front wheel 20, the rear wheel 30 is coupled to the frame 10 In the small wheel bicycle (1), the auxiliary rear wheel 31 is connected to the rear wheel 30 by the sprocket 13, the chain 14 and the chain 31a and driven together, and the front wheel 20 has an auxiliary front wheel ( 21 is mounted to rotate the handle 11 is to be achieved by a small wheel bike, characterized in that the steering is made by being connected to the chain (21a) at the same time.

이상에서 상술한 바와 같은 본 발명은, 앞바퀴(20), 보조 앞바퀴(21), 뒷바퀴(30), 보조 뒷바퀴(31) 4개의 바퀴로 구성되어 노면에 넓게 접촉하면서 주행하는 것이므로 부드러운 주행이 이루어지면서도 2개의 앞바퀴(20)(21)들이 함께 조향되어 주행성을 높여줄 수 있는 것으로서 작은 바퀴 자전거(1)의 대외 경쟁력을 최대 한 높여줄 수 있는 등의 이점이 있는 것이다.As described above, the present invention is composed of four wheels, the front wheel 20, the auxiliary front wheel 21, the rear wheel 30, and the auxiliary rear wheel 31, so that the vehicle travels in wide contact with the road surface. As shown in FIG. 2, the front wheels 20 and 21 may be steered together to increase driving performance, such as to increase the external competitiveness of the small wheel bicycle 1 as much as possible.

이하, 상기한 목적을 달성하기 위한 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지는 도 2에서 도시한 바와 같이, 작은 바퀴 자전거(1)는 프레임(10)에 핸들(11), 페달(12), 스프로킷(13), 체인(14), 앞바퀴(20), 뒷바퀴(30)들이 결합구성으로 되어 있다.As shown in FIGS. 1 and 2, the small wheel bicycle 1 includes a handle 11, a pedal 12, a sprocket 13, a chain 14, a front wheel 20, and a rear wheel on a frame 10. 30 are combined.

물론 전술한 구성으로 이루어진 작은 바퀴 자전거(1)는 이미 알려진 공지의 기술사상이다.Of course, the small-wheeled bicycle 1 having the above-described configuration is a known art.

그러나, 본 발명에 있어서 가장 중요한 특징은 보조 앞바퀴(21) 및 보조 뒷바퀴(31)가 설치되도록 하여 주행성을 높여 줄 수 있도록 한 것에 있다.However, the most important feature in the present invention is that the auxiliary front wheel 21 and the auxiliary rear wheel 31 are installed so as to increase the running performance.

즉, 상기 뒷바퀴(30)에는 보조 뒷바퀴(31)가 스프로킷(13) 및 체인(14)(31a)으로 연결되어 함께 구동될 수 있도록 구성되어 있다.That is, the rear wheel 30 is configured so that the auxiliary rear wheel 31 is connected to the sprocket 13 and the chain 14, 31a can be driven together.
