한편 변속장치(40)는 도 6에 도시된 바와 같이 차체 프레임(4)에 스프링(47)으로 탄지 축설되는 지지판(41), 지지판의 양측에 슬라이드이동 가능하게 설치되는 안내기어(14)(14'), 상기 양 안내기어를 탄지시키는 스프링(42), 상기 양 안내기어(14)(14') 사이에 축설되는 캠부재(43), 및 후륜(1)축의 양측에 설치되는 변속기어(44)를 포함한다.Meanwhile, as shown in FIG. 6, the transmission 40 includes a support plate 41 which is supported by a spring 47 on the body frame 4, and guide gears 14 and 14 which are slidably installed on both sides of the support plate. '), A spring 42 for holding both of the guide gears, a cam member 43 arranged between the both guide gears 14 and 14', and a transmission gear 44 provided on both sides of the rear wheel 1 shaft. ).

상기 구동체인(16)(28)은 전후륜의 일방향기어(15)(27)를 감싸는 부분만을 구성할 수 있고 나머지 부분은 와이어로 구성할 수 있다.The drive chains 16 and 28 may constitute only a portion surrounding the one-way gears 15 and 27 of the front and rear wheels, and the remaining portions may be formed of wires.

상기 구성으로 된 본 발명의 작용효과를 설명한다.The effect of this invention of the said structure is demonstrated.

먼저 후륜(1)만을 구동시켜 주행하는 방법을 설명한다. 이 때에는 양 핸들(21)(21')을 고정시킨다.First, a method of driving by driving only the rear wheel 1 will be described. At this time, both handles 21 and 21 'are fixed.

즉 타측 핸들(21')을 들어 올려 잠금레버(31)의 끝단이 핸들축에 형성된 잠금구멍(21a)으로 일치시킨 후 상기 잠금레버(31)를 제키게 되면 잠금레버(31)의 끝단이 잠금구멍(21a)으로 삽입되고, 또 다른 잠금레버(32)를 타측 핸들(21)에 설치된 고정구멍(30)으로 삽입시키게 되면 양 핸들(21)(21')은 동일한 각도를 유지하여 핸들축상에 고정된다.That is, the other end of the lock lever 31 is locked when the other end of the lock lever 31 is raised by matching the end of the lock lever 31 with the lock hole 21a formed in the handle shaft. When inserted into the hole 21a and another locking lever 32 is inserted into the fixing hole 30 provided in the other handle 21, both handles 21 and 21 'maintain the same angle on the handle shaft. It is fixed.

이러한 상태에서 자전거에 탑승하게 되면 탑승자의 양 발은 전방으로 향한 양 페달(13)상에 올려지게 된다.In this state, when riding on a bicycle, the passenger's feet are raised on both pedals 13 facing forward.

페달(13)을 밟게 되면 그 페달기어(12)가 회전하게 되고, 이에 따라 구동체인(16)이 끌어당겨져 일방향기어(15)를 회전시키게 됨으로써 후륜(1)이 전진 방향으로 회전된다.When the pedal 13 is pressed, the pedal gear 12 is rotated, and thus the driving chain 16 is attracted to rotate the one-way gear 15 so that the rear wheel 1 is rotated in the forward direction.

또 다시 타측의 페달(13)을 밟게 되면 일측의 페달(13)이 올라와 마침내 그 차단턱(12a)이 변속장치(40)를 구성하는 지지판(41) 양측의 스톱퍼(45)에 걸리게 됨으로써 더 이상의 회전이 차단되는 것에 의해 페달(13)을 종래에서와 같이 360°회전시킬 필요가 없이도 주행이 가능하게 된다.When the pedal 13 on the other side is pressed again, the pedal 13 on one side rises and finally the blocking jaw 12a is caught by the stoppers 45 on both sides of the support plate 41 constituting the transmission 40. By turning off the rotation, it is possible to travel without having to rotate the pedal 13 by 360 degrees as in the prior art.

상기 스톱퍼(45)는 스프링(46)으로 탄지되어 있어 완충작용과 함께 다음 동작에 탄력을 갖게 한다.The stopper 45 is supported by a spring 46 to give elasticity to the next operation with the cushioning action.

주행상태에서 변속을 위해서는 변속장치(40)를 조작함으로써 가능하다.In order to shift in the running state, it is possible by operating the transmission 40.

즉, 핸들상에 설치된 변속레버(미도시)를 조작하게 되면 상기 변속레버와 와이어로 연결된 캠부재(43)가 작은 반경으로 회전하게 되고 그러면 양 안내기어(14)(14')는 스프링(42)의 복원력으로 중심을 향하여 슬라이딩 이동하여 그 사이를 좁히게 된다.That is, when the shift lever (not shown) installed on the handle is operated, the cam member 43 connected to the shift lever and the wire rotates with a small radius. Then, both the guide gears 14 and 14 'are springs 42. Sliding movement toward the center by the restoring force of) narrows the gap between them.

이에 따라 상기 양 안내기어(14)(14')에 지지되고 있는 구동체인(16)이 그만큼 쳐지는 현상에 의해 여유있는 길이를 지니게 되어 후륜축의 양측에 설치된 소망하는 변속기어(44)에 걸어지게 된다.As a result, the driving chain 16 supported by both of the guide gears 14 and 14 'is struck so much so that the driving chain 16 can be hung on a desired transmission gear 44 provided on both sides of the rear wheel shaft. do.

한편 후륜(1)을 구동시켜 주행하는 것과 동시에 전륜(2)을 구동시켜 주행하거나 상기 전륜(2)만을 구동시켜 주행하는 방법을 설명한다.Meanwhile, a method of driving by driving the rear wheel 1 and driving by driving the front wheel 2 or by driving only the front wheel 2 will be described.

이 때에는 먼저 양 핸들(21)(21')의 고정상태를 변경시켜야 한다.At this time, the fixed state of both handles 21 and 21 'must be changed first.

즉, 양 핸들(21)(21')을 동일한 각도로 유지한 상태로 상하로 회동시켜 전륜을 구동시킬 경우에는 잠금레버(31)를 해제시킨 상태로, 잠금레버(32)를 고정시킨 상태로 유지한다.In other words, when driving the front wheels by rotating the handles 21 and 21 'at the same angle and moving up and down, the lock lever 32 is released and the lock lever 32 is fixed. Keep it.

이러한 상태에서 양 핸들(21)(21')을 상하로 회동시키게 되면 양 핸들의 끝단에 설치된 핸들기어(22)(22')의 회전에 의해 베벨기어(24)가 회전하게 되고, 상기 베벨기어(24)는 구동기어(25)를 회전시키게 되며, 이에 걸어진 구동체인(28)이 일방향기어(27)를 회전시키게 됨으로써 전륜(2)이 회전된다.In this state, when the handles 21 and 21 'are rotated up and down, the bevel gear 24 is rotated by the rotation of the handle gears 22 and 22' installed at the ends of the handles. 24 rotates the drive gear 25, the front wheel 2 is rotated by the drive chain 28 is rotated to rotate the one-way gear (27).

이 때 양 핸들의 회동폭은 핸들기어(22)(22')의 끝단에 형성된 차단턱(22a)이 프레임(3)에 형성된 스톱퍼(29)에 걸리기 까지의 반경거리가 된다.At this time, the rotation width of both handles is a radial distance from the blocking jaw 22a formed at the end of the handle gears 22 and 22 'to be caught by the stopper 29 formed in the frame 3.

한편, 양 핸들(21)(21')을 소정의 각도로 엇갈리게 하여 지그재그 방식으로 회동시켜 전륜을 구동시킬 경우에는 잠금레버(31)를 잠금시킨 상태로, 잠금레버(32)를 해제시킨 상태로 유지한다.On the other hand, when the two wheels 21 and 21 'are rotated by a predetermined angle and rotated in a zigzag manner to drive the front wheels, the lock lever 31 is locked and the lock lever 32 is released. Keep it.
