본 고안은 자전거의 전륜보조구동장치에 관한 것으로, 특히 조향핸들을 변형시켜 이에 손페달을 구성하고 이로써 손페달기어를 회전시키므로서 전륜을 전진구동시킬 수 있도록 한 자전거의 전륜보조구동장치에 관한 것이다.The present invention relates to a front wheel auxiliary drive device of a bicycle, and more particularly, to a front wheel auxiliary drive device of a bicycle to deform the steering wheel to form a hand pedal and thereby to drive the front wheel by rotating the hand pedal gear. .

일반적으로, 자전거의 구동장치는 페달에 결합된 페달기어가 뒷바퀴의 허브에 결합된 후륜기어에 체인으로 연결되게 구성되어 탑승자가 발로 페달을 회전구동시키므로서 자전거가 추진될 수 있게 되어 있다.In general, the driving device of the bicycle is configured such that the pedal gear coupled to the pedal is chained to the rear wheel gear coupled to the hub of the rear wheel so that the rider can drive the pedal by rotating the pedal by foot.

본 고안에 있어서는 이러한 후륜구동장치와는 별도로 전륜을 구동시킬 수 있는 자전거의 전륜보조구동장치가 제공되는바, 전륜의 포크축상에 기어축을 축설하여 이에 손페달기어를 착설하고 기어축의 양측에 크랭크형의 손페달을 형성하며 손페달의 단부에는 기어축의 축선과 동일축선상에 조향핸들을 일체로 형성하고 전륜의 허브에 역방향공회전형의 전륜구동기어를 착설하여 손페달기어와 전륜구동어를 체인으로 연결하므로서 평상시 발로 구동하는 페달기어에 의한 자전거의 전진이 이루어지도록 하였다가 손으로 구동하고자 할때에는 손페달을 잡고 손페달기어를 회전시켜 자전거의 보조구동이 이루어지도록 한 것이다.In the present invention, a front wheel auxiliary drive device for a bicycle capable of driving front wheels separately from the rear wheel drive device is provided. It forms a hand pedal of the hand pedal, and at the end of the hand pedal, the steering wheel is integrally formed on the same axis as the axis of the gear shaft. By connecting, the bicycle is normally driven by the pedal gear that is driven by the foot, and when it is to be driven by hand, the hand pedal is rotated and the hand pedal gear is rotated so that the auxiliary driving of the bicycle is performed.

본 고안을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as follows.

전륜(10)의 허브(12)가 결합되는 포크(14)의 상부측으로 연장된 포크축(16)이 프레임(18)에 결합되고 프레임(18)의 하측에 페달기어(20)가 착설되어 체인(22)으로 후륜(24)의 후륜기어(26)에 연결된 것에 있어서, 포크축(16)의 상부에 수평으로 기어축(28)을 축설하여 이에 손페달기어(30)를 착설하고 손페달기어(30)의 양측에 크랭크형으로 손페달(32)을 형성하며 이 손페달(32)의 단부에 기어축(28)과 동축상으로 조향핸들(34)을 형성하고, 전륜(10)의 허브(12)에 전륜구동기어(36)를 착설하여 손페달기어(30)와 전륜구동기어(36)를 체인(38)으로 연결하여서된 구조이다.The fork shaft 16 extending to the upper side of the fork 14 to which the hub 12 of the front wheel 10 is coupled is coupled to the frame 18, and the pedal gear 20 is installed on the lower side of the frame 18 so that the chain (22) connected to the rear wheel gear 26 of the rear wheel 24, the gear shaft 28 is laid horizontally on the upper portion of the fork shaft 16 to install the hand pedal gear 30 to the hand pedal gear Crank-shaped hand pedals 32 are formed on both sides of the 30, and steering wheels 34 are formed coaxially with the gear shaft 28 at the ends of the hand pedals 32, and the hub of the front wheel 10 is formed. The front wheel drive gear 36 is installed at 12 to connect the hand pedal gear 30 and the front wheel drive gear 36 with a chain 38.

이와 같은 본 고안은 평상시 손으로 조향핸들(34)을 잡고 전륜(10)을 조향하면서 발로 후륜(24)을 구동시키는 페달기어(20)를 회전시켜 자전거를 추진하며, 직선도로에서 또는 약간의 전륜조향만이 요구되는 곡선도로에서 발을 쉬고 손으로 자전거를 전진구동시키고자 할때에는 발을 쉬고 손으로 크랭크형의 손페달(32)을 잡은 다음 이를 회전시켜 손페달기어(30)을 통하여 전륜구동기어(36)에 전달되어 전륜(10)의 전진구동이 이루어질 수 있다.This invention is designed to propel the bicycle by rotating the pedal gear 20 to drive the rear wheel 24 with the foot while steering the front wheel 10 by holding the steering wheel 34 with the usual hand, on a straight road or a slight front wheel When you want to rest your feet on a curved road where steering is required and to drive the bicycle forward with your hands, rest your feet and hold the crank-type hand pedal 32 with your hands and then rotate it to drive the front wheel through the hand pedal gear 30. The forward driving of the front wheel 10 may be performed by being transmitted to the gear 36.
