Field of the Invention The present invention relates to a secondary propulsion driving device of a bicycle that generates propulsion by using a weight of a passenger acting on a saddle mounted on a bicycle. The crank gear is pedaled by the bending force of a passenger's leg to propel a bicycle. When the bicycle is rotated, the bicycle occupant accumulates the compressive elasticity in the compression coil springs 27 and 27a mounted on the lower saddle at the weight of the occupant sitting on the saddle 19 of the bicycle. In order to rotate the crank gear 26 by stepping on the pedal 25 with the flexing force of the occupant's leg, the occupant acting on the saddle 19 as much as the flexing force of the occupant's leg by the load on the rear wheel 17. The weight is shifted by the pedal 25, the compressive elasticity accumulated in the compression coil springs 27, 27a is released as much as the weight moved by the pedal 25, the lifting section 28 is raised to the rack 21 andThe driving force generated in the engaged pinion 22 rotates the freewheel gear 24 through the chain 15 to assist the propulsion drive of the bicycle. Conventional propulsion drive of the bicycle is a rear wheel by rotating the crank sprocket (crank sprocket) by the weight of the occupant by the force of the pedal (pedal) to simply step on the pedal of the occupant without the auxiliary propulsion drive. Propulsion of the bicycle with the driving force of, but there is no means to recycle the reinforcement (physical energy) of the bridge that is consumed to rotate the crank gear was a lot of physical consumption, especially when driving on hills.

본 발명은 탑승자가 새들(saddle)에 앉을때 실리는 탑승자의 체중을 이용하여 새들(19)의 하부에 장착된 압축코일스르링(27,27a)에 압축탄력(壓縮彈力)을 축적하여서, 축적된 탄력작용을 회전력으로 전환시키는 수단으로 하는 자전거 보조추진 구동장치에 관한 것으로, 자전거 탑승자의 체중으로 새들(19)에 앉아 새들(19) 하부에 장착된 압축코일스프링(27,27a)에 압축탄력을 축적하여 두었다가, 자전거를 추진시키기 위하여 탑승자 다리의 굴신력으로 페달(25)을 밟아 탑승자의 체중을 페달(25)로 이동시기면, 이동된 탑승자의 체중 만큼 새들(19)에 실리는 체중이 감소하여 압축코일스프링(27,27a)에 축적된 압축탄력이 방출하여 승강간(28)이 상승되어 래크(21)와 치합된 피니온(22)에 발생된 구동력으로 스프로킷(23)과 체인(15)을 통하어 프리휠기어(24)를 회전시켜서 후륜(17)을 추진시키는 수단으로 하는 보조추진 구동장치이다. 예를 들면, 80Kg의 탑승자 체중으로 새들(19)에 앉아서 압축코일스프링(27,27a)에 80Kg의 압축탄력을 축적하여 두었다가, 탑승자 다리의 굴신운동으로 페달(25)를 밟아30Kg의 체중을 페달(25)로 이동시키면 새들(19)에 실린 탑승자 체중이 50Kg으로 감소하여 압축코일스프링(27,27a)에 축적된 80Kg의 압축탄력중에 30Kg의 압축탄력이 방출되어, 승강간(28)이 30Kg의 상승력이 발생하여 래크(21)와 치합된 피니온(22)에 발생된 구동력으로 체인(15)를 통하어 프리휠기어(24)를 회전시켜 후륜(17)을 추진시키는 원리.The present invention accumulates and compresses the compressive elasticity in the compression coil through ring (27, 27a) mounted on the lower portion of the saddle 19 by using the weight of the occupant when the occupant sits on the saddle (saddle) The present invention relates to a bicycle auxiliary propulsion drive as a means for converting a resilient action into rotational force, the compression elastic force of the compression coil spring (27, 27a) mounted under the saddle (19) sitting on the saddle (19) at the weight of the rider After accumulating and moving the pedals 25 with the pedals 25 by the pedaling force of the occupant's legs to propel the bicycle, the weight carried on the saddle 19 is reduced by the weight of the moved occupants. The compression elastic force accumulated in the compression coil springs (27, 27a) is released to raise and lower the lifting interval (28) so that the sprocket (23) and the chain (15) with the driving force generated in the pinion (22) engaged with the rack (21). By rotating the freewheel gear (24) It is an auxiliary propulsion drive device which propels the rear wheel 17. For example, sitting on the saddle 19 at 80Kg of passenger weight, 80Kg of compressive elasticity was accumulated in the compression coil springs 27 and 27a, and the pedal 25 was pressed by the pedaling exercise of the passenger's leg to pedal the weight of 30Kg. Moving to (25), the weight of the occupant on the saddle 19 is reduced to 50 kg, and 30 kg of compressive elasticity is released among the 80 kg of compressive elasticity accumulated in the compression coil springs 27 and 27a, and the lifting leg 28 is 30 kg. The driving force generated in the pinion (22) engaged with the rack (21) by the rising force of the principle to propel the rear wheel (17) by rotating the freewheel gear (24) through the chain (15).

이와 같은 수단으로, 반복되는 탑승자 다리의 굴신운동으로 다리가 굽혀질때 탑승자 체중에 의하여 새들(19)이 하강하여 압축코일스프링(27,27a)에 반복 판력이 축적되어, 압축코일스프링(27,27a)에 축적된 압축탄력작용을 회전력으로 전환시켜서 계속 후륜(17)에 추진력을 가(加) 자전거의 보조추진 구동장치이다.By this means, the saddle 19 is lowered by the weight of the occupant when the leg is bent by the repeated movement of the occupant's leg, and the repeated platen is accumulated in the compression coil springs 27 and 27a, thereby compressing the coil coils 27 and 27a. It is an auxiliary propulsion drive device for the bicycle which adds the driving force to the rear wheel 17 by converting the compressive elasticity action accumulated in the wheel into rotational force.

본 발명의 자전거의 보조추진 구동장치 작용을 설명하면, 탑승자가 자전거 새들(19)에 앉으면 탑승자의 체중으로 새들(19)이 하강하여 압축코일스프링(27,27a)을 변형시켜서 압축코일스프링(27,27a)에 압축탄력(壓縮彈力)이 축적된다. 탑승자 다리의 굴신력으로 페달(25)을 밟아 크랭크기어(26)를 구동시켜서 체인(14)를 통하여 프리휠기어(18)을 회전시켜서 후륜(17)을 추진시킬때, 후륜(17)에 걸리는 부하(負荷)에 의하여 탑승자 체중이 페달(25)로 이동하면, 새들(19)에 실린 탑승자 체중이 감소하여 압축코일스프링(27,27a)에 축적된 탄력이 방출되어 압축코일스프링(27)의 탄력작용으로 승강간(28)이 상승한다.Referring to the operation of the auxiliary propulsion drive of the bicycle of the present invention, when the occupant sits on the bicycle saddle 19, the saddle 19 is lowered to the weight of the occupant to deform the compressed coil springs (27, 27a) to compress the coil spring (27) The compressive elasticity is accumulated at 27a). The load applied to the rear wheels 17 when the rear wheels 17 are pushed by pushing the pedals 25 to drive the crank gears 26 to rotate the freewheel gears 18 through the chains 14 by the flexing force of the occupant's legs. When the weight of the occupant is moved to the pedal 25 by (iii), the weight of the occupant carried on the saddle 19 is reduced, and the elasticity accumulated in the compression coil springs 27 and 27a is released to give the elasticity of the compression coil spring 27. In operation, the lifting interval 28 is raised.

따라서, 승강간(10)에 고정장착된 래크(21)와 치합된 피니온(22)에 후륜(17)의 추진방향으로 구동력이 발생되어, 피니온(22)의 구동력이 스프로킷(23)을 회전시켜서 체인(15)으로 연결된 프리휠기어(24)가 연동하여 후륜(17)에 보조추진력을 가(加) 한다.Therefore, the driving force is generated in the propulsion direction of the rear wheel 17 to the pinion 22 meshed with the rack 21 fixedly mounted on the lifting leg 10, so that the driving force of the pinion 22 is applied to the sprocket 23. The freewheel gear 24 connected to the chain 15 by rotating rotates an auxiliary thrust force to the rear wheel 17.
