자전거 일방향 동력전달장치{ONE-WAY POWER TRANSMISSION DEVICE OF BICYCLE}Bicycle one-way power train {ONE-WAY POWER TRANSMISSION DEVICE OF BICYCLE}

본 발명은 자전거의 동력전달장치에 관한 것으로서 특히, 자전거의 페달을 앞으로 구동하였을 때뿐만 아니라 뒤로 구동하였을 경우에도 자전거를 앞으로 주행시킬 수 있는 것으로서, 정방향 구동 및 뒤로끌기시는 일반 자전거와 동일하게 부하없이 전진 구동 및 뒤로 끌기가 가능하고, 역방향구동시는 별도의 제어레버 조작에 의하여 간단히 자전거를 앞으로 주행시킬수 있으며, 구조가 간단하여 부피를 적게 차지하므로 앞바퀴의 축하우징 내에 자유로이 설치될 수 있는 자전거의 일방향동력전달장치에 관한 것이다.The present invention relates to a power transmission device of a bicycle, and in particular, to be able to drive the bicycle forward not only when the pedal is driven forward but also when driven backward, forward driving and dragging the same as a normal bicycle load It can be driven forward and backward without dragging, and in reverse driving, the bicycle can be driven forward by a separate control lever, and the structure is simple and occupies a small volume. It relates to a one-way power transmission device.

일반적인 자전거는 페달의 정방향구동에 의한 전진주행만이 가능하여 장시간 주행할 경우에 사용자의 다리를 쉽게 피로하게 하며 또한, 다리근육의 발달을 불균일하게 하는 문제점이 있었다.In general, the bicycle can be forward driven only by the forward driving of the pedal, so that the user's legs are easily tired when running for a long time, and there is a problem of uneven development of the leg muscles.

이러한 문제점을 개선하기 위해 정방향구동에 의한 전진구동만 가능한 통상의 자전거를 정,역 양방향으로 구동하여 일방향으로 출력할수 있는 장치(이하 "일방향 동력전달장치" 라함)를 개발하기 위하여 여러 발명가들이 노력하여 왔다.In order to solve this problem, various inventors have tried to develop a device capable of outputting in one direction by driving a normal bicycle capable of forward driving only by forward driving in both forward and reverse directions (hereinafter referred to as "one-way power transmission device"). come.

지금까지 개발된 일방향 동력전달장치는 크게 보조기어를 이용한 방법과 베벨기어를 이용한 방법 그리고 유성기어를 이용한 방법으로 구분할 수가 있다.The unidirectional power train developed so far can be divided into two methods: auxiliary gear, bevel gear, and planetary gear.

그러나, 이들 발명들은 대부분 구조가 복잡할뿐 아니라 특히 유성기어를 이용한 방법은 안기어와 바깥기어 사이에 별도의 유성기어가 회전하여여야 함으로 부피가 커지게 되어 제조단가가 올라가게 되고 또한, 안기어, 바깥기어 그리고 유성기어가 별도의 축을 가져야 함으로 동력전달이 불안정한 결점이 있었다.However, most of these inventions are complicated in structure, and in particular, the planetary gear method requires a separate planetary gear to rotate between the inner gear and the outer gear, thereby increasing the volume and increasing the manufacturing cost. Because of the fact that the external gears and the planetary gears must have separate shafts, power transmission is unstable.

따라서 이러한 문제점들로 인하여 상기의 일방향 동력전달장치들은 실제 자전거에 적용하여 사용하기는 제한적일 수밖에 없었다.Therefore, due to these problems, the one-way power transmission devices have to be limited to be applied to the actual bicycle.

본 발명은 상기의 결점을 해소하기 위한것으로, 자전거의 페달(11)을 정방향 구동시뿐만 아니라 역방향 구동시에도 자전거를 앞으로 주행시킬 수 있을뿐 아니라 뒤로 끌기가 가능하며, 구조가 간단하여 부피를 적게 차지하므로 앞바퀴의 축하우징(51) 내에 자유로이 설치될 수 있고, 역방향 구동시는 핸들에 설치되는 별도의 조작레버에 의하여 간단히 자전거를 앞으로 주행시킬수 있으며, 정방향 구동 및 뒤로 끌기시에는 일반자전거와 동일하게 정방향구동 및 뒤로 끌기가 가능한 자전거의 일방향 동력전달장치를 제공하고자 한다.The present invention is to solve the above-mentioned drawback, the bicycle 11 can be driven forward as well as forward in the reverse direction as well as the forward driving of the pedal 11 of the bicycle, it is possible to drag backward, the structure is simple, the volume is small Because it occupies, it can be installed freely in the front housing 51 of the front wheel, and in the reverse driving can be simply driven forward by a separate operating lever installed on the handle, and when driving in the forward and backward, the same as the general bicycle It is an object of the present invention to provide a one-way power train of a bicycle capable of driving forward and pulling back.

The carrier control unit 70 is inserted into the groove to limit the rotation of the carrier 31 to enable reverse driving.

상기 동력전달부내 정방향 클러치 베어링(22)과 역방향 클러치 베어링(24)은 페달축(10)의 동력을 제1.3베벌기어(21,23)에 일방향 전달하기 위한 장치로서 상기 부품에 한정되는 것은 아니며, 일방향 동력전달 장치인 래칫등을 사용하여도 동일한 효과를 낼수 있으므로 무방하다.The forward clutch bearing 22 and the reverse clutch bearing 24 in the power transmission unit are devices for transmitting the power of the pedal shaft 10 to the 1.3 bevel gears 21 and 23 in one direction, but are not limited to the above components. The same effect can be achieved by using a ratchet lamp, which is a one-way power transmission device.

또한, 일방향 동력전달장치로서 상기 정,역방향클러치 베어링 (22,24)을 사용할때는 정,역방향클러치 베어링(22,24)의 내주면과 페달축(10), 그리고 외주면과 제1,3베벌기어(21,23) 사이에는 슬리핑이 일어나서는 안되므로, 정,역방향 클러치 베어링(22,24)의 특성에 따라 키이등에 의한 별도의 체결수단을 추가할수 있다.In addition, when the forward and reverse clutch bearings 22 and 24 are used as one-way power transmission devices, the inner circumferential surface and the pedal shaft 10 of the forward and reverse clutch bearings 22 and 24, and the outer circumferential surface and the first and third bevel gears ( Sleeping should not occur between the 21 and 23, it is possible to add a separate fastening means by the key or the like according to the characteristics of the forward and reverse clutch bearings (22, 24).

도 2는 도 1의 A-A에서 본 동력변환부의 요부 상세 단면도를 나타낸 것이다, 상기 동력변환부는 페달축(10)을 역방향으로 구동시에도 스플라켓(42)은 항상 정방향으로 회전할수 있도록 회전방향을 변환하기 위해 설치된 수단으로서, 페달축(10)에 회전 가능하게 내주면이 축결속되고, 외주면은 축하우징(51)에 회전 가능하도록 삽입되며, 외주면 주위로 일정간격으로 고정핀(71)용 구멍이 형성되어진 원통형상의 케리어(31)와, 상기 캐리어(31) 몸체 주위 3-4곳에 일정간격으로 설치되는 제2베벌기어(32)로 구성된다.Figure 2 shows a detailed cross-sectional view of the main portion of the power converter as seen from AA of FIG. 1, the power converter converts the rotation direction so that the sprocket 42 can always rotate in the forward direction even when the pedal shaft 10 is driven in the reverse direction As an installed means, the inner circumferential surface is axially coupled to the pedal shaft 10, and the outer circumferential surface is inserted to be rotatable in the celebratory housing 51, and a hole for the fixing pin 71 is formed at a predetermined interval around the outer circumferential surface. It is composed of a cylindrical carrier 31 and a second bevel gear 32 which is installed at a predetermined interval around the carrier 31 body 3-4.

상기 제2베벌기어(32)는 페달축(10) 중심선 방향으로 형성되는 회전축(33)에의해 회전 가능하도록 축결속되어 구성되며. 제1베벌기어(21) 및 제3베벌기어와 치결속되어 구속회전할수 있도록 구성된다.The second bevel gear 32 is axially coupled so as to be rotatable by a rotation shaft 33 formed in the direction of the center line of the pedal shaft 10. The first bevel gear 21 and the third bevel gear are engaged with each other and are configured to restrain rotation.

캐리어(31)상부측 축하우징(51) 바깥쪽 일측에는 캐리어제어부(70)가 고정설치되며, 캐리어(31)의 회전을 제어하기 위한 고정용 핀(71), 복귀 스프링(74), 제어레버(도면 미 도시됨), 플렉시블 와이어(73)로 구성된다.A carrier control unit 70 is fixedly installed at one side of the outer side of the upper housing 31 and the carrier 31, and a fixing pin 71, a return spring 74, and a control lever for controlling the rotation of the carrier 31. (Not shown in the figure), a flexible wire 73 is provided.

통상적인 정방향 구동시에는 핸들에 취부되는 제어레버의 조작에 의해 플렉시블 와이어(73)를 당겨 캐리어 고정용핀(71)이 캐리어(31)에서 이탈되어 캐리어(31)가 회전가능하게 구성된다.In the normal forward driving, the carrier fixing pin 71 is pulled out of the carrier 31 by pulling the flexible wire 73 by the control lever mounted on the handle, so that the carrier 31 is rotatable.

만약, 역구동시는 제어레버를 복귀함으로써 복귀스프링(74)에 의하여 캐리어 고정용 핀(71)이 캐리어(31) 외주면에 형성되어 있는 홈에 삽입됨으로써 캐리어(31)가 고정되어 역구동이 가능하게 되는 것이다.In case of reverse driving, by returning the control lever, the carrier fixing pin 71 is inserted into the groove formed on the outer circumferential surface of the carrier 31 by the return spring 74 so that the carrier 31 is fixed so that the reverse driving is possible. Will be.

도3은 본 발명의 동력전달부 및 동력변환부의 구성상태를 나타낸 반단면 상태의 사시도로서, 도면상의 회전방향은 페달(11)의 정,역 구동시 각 구성요소가 회전 할수 있는 방향을 함께 나타낸 것이다.Figure 3 is a perspective view of a half cross-sectional view showing the configuration of the power transmission unit and the power conversion unit of the present invention, the rotational direction in the drawing shows the direction in which each component can be rotated during the forward and reverse driving of the pedal (11) will be.

즉, 페달(11)의 정,역 구동시 페달축(10), 제1베벌기어(21), 제3베벌기어(23), 캐리어(31) 가 정,역 회전할수 있으며, 제2베벌기어(32)는 회전축(33)을 중심축으로 좌,우로 자전을 할수 있음을 나타내고 있다.That is, the pedal shaft 10, the first bevel gear 21, the third bevel gear 23, the carrier 31 can be rotated forward and reverse when the pedal 11 is driven forward and reverse, and the second bevel gear is rotated. Reference numeral 32 indicates that the rotational shaft 33 can be rotated left and right about the central axis.

도 4는 본 발명의 정방향 구동시의 동작상태도를 나타낸 사시도로서, 회전방향중 실선은 케리어 제어부 고정용핀(71)에 의해 캐리어(31)가 고정된 상태의 회전상태를 나타낸 것이고, 점선은 캐리어(31)가 자유회전 할때의 회전상태를 나타낸것이다.4 is a perspective view showing an operating state diagram in the forward driving of the present invention, the solid line in the rotational direction shows the rotation state of the carrier 31 is fixed by the carrier control pins 71, the dotted line is a carrier ( 31) shows the rotation status when free rotation.

사용자가 페달(11)을 정방향(도면상 시계방향 화살표) 구동시키면 이것과 연결된 페달축(10)또한 동일한 방향으로 구동되게 된다.When the user drives the pedal 11 in the forward direction (clockwise arrow in the drawing), the pedal shaft 10 connected thereto is also driven in the same direction.

상기 페달축(10)이 정방향 구동하게 되면 이와 연결된 정방향클러치 베어링(22)은 페달축(10)의 회전력을 우측의 제1베벌기어(21)로 전달하게 되고, 이것은 다시 이것과 결속되어 있는 연결관(41)을 회전시키게 되며, 이것은 다시 키이(52)에 의해 스프라켓(42)을 정회전시키게 되므로 스프라켓(42)에 연결된 체인(도면 미도시됨)에 의해 후륜에 동력을 전달함으로서 자전거를 전진구동할수 있게된다.When the pedal shaft 10 is driven in the forward direction, the forward clutch bearing 22 connected thereto transmits the rotational force of the pedal shaft 10 to the first bevel gear 21 on the right side, which is in turn connected thereto. The tube 41 is rotated, which in turn rotates the sprocket 42 forward by the key 52 so that the bicycle is advanced by transmitting power to the rear wheel by a chain (not shown) connected to the sprocket 42. It can be driven.

이때 상기 케리어 제어부 고정용핀(71)에 의해 캐리어(31)가 고정되어 있다면 상기 제1베벌기어(21)가 회전함으로 인해 제1베벌기어(21)와 치결속되어 있는 제2베벌기어(32)가 반시계방향으로 회전(자전)을 하게 되고, 이것은 다시 이것과 맞물려 있는 좌측의 제3베벌기어(23)를 반시계방향으로 회전시키게 되지만 역방향 클러치 베어링(24)에 의해 공회전하게 된다.At this time, if the carrier 31 is fixed by the carrier control pin 71, the second bevel gear 32 is engaged with the first bevel gear 21 due to the rotation of the first bevel gear 21. Rotates counterclockwise (rotating), which in turn rotates the third bevel gear 23 on the left in counterclockwise direction, but is idling by the reverse clutch bearing 24.

또한, 상기 케리어 제어부(70)의 캐리어고정용핀(71)에 의해 캐리어(31)가 고정되지 않고 자유로이 회전할 수가 있다면 도4의 점선과 같이 제1베벌기어(21),제2베벌기어(32), 제3베벌기어(23) 그리고 캐리어(31)가 일체가 되어 정방향 회전하게 되므로 이때에도 자전거를 정방향 회전시킬수 있게된다.In addition, if the carrier 31 is not fixed by the carrier fixing pin 71 of the carrier controller 70, the first bevel gear 21 and the second bevel gear 32 may be rotated as shown in FIG. 4. ), The third bevel gear 23 and the carrier 31 is integrally rotated forward so that the bicycle can be rotated forward.

즉, 정방향 구동시는 케리어(31)가 캐리어고정용핀(71)에 의해 고정되든지, 또는 회전되든지에 관계없이 자전거를 전진 주행할 수가 있게 되는 것이다.That is, in the forward driving, the carrier 31 can drive the bicycle forward regardless of whether the carrier 31 is fixed or rotated by the carrier fixing pin 71.

도 5는 본 발명의 역방향 구동시의 동작상태를 나타낸 사시도이다.5 is a perspective view showing an operating state in the reverse driving of the present invention.

역방향으로 구동시는 먼저 동력변환부의 캐리어(31) 외주면에 형성된 구멍에 캐리어 고정용핀(71)을 삽입하여 캐리어(31)가 회전되지 않도록 고정시키게 된다.When driving in the reverse direction, the carrier fixing pin 71 is inserted into a hole formed in the outer circumferential surface of the carrier 31 of the power converter to fix the carrier 31 not to rotate.

사용자가 페달(11)을 역방향(도면상 역시계방향) 구동시키면 페달축(10) 또한 동일한 방향으로 역방향 구동되게 된다.When the user drives the pedal 11 in the reverse direction (also in the drawing), the pedal shaft 10 is also driven backward in the same direction.

그러면 상기 좌측의 역방향 클러치 베어링(24)에 의해 페달축(10)의 동력은 제3베벌기어(23)로 회전력이 전달되고, 이것은 다시 이것과 맞물려 치결속되어 있는 제2베벌기어(32)를 자전시키게 되며, 이것과 맞물려 치결속 되어있는 우측의 제1베벌기어(21)를 시계방향으로 회전시키게 된다.Then, the driving force of the pedal shaft 10 is transmitted to the third bevel gear 23 by the reverse clutch bearing 24 on the left side, which again engages with the second bevel gear 32 that is engaged. It rotates and rotates in the clockwise direction the first bevel gear 21 on the right side engaged with it.

제1베벌기어(21)가 시계방향으로 회전을 하게 되면 정방향 구동시와 마찬가지로 연결관(41)을 거쳐 스프라켓(42)을 회전시키게 되므로 자전거를 앞으로 전진시킬 수 있게 된다.When the first bevel gear 21 rotates in the clockwise direction, the sprocket 42 is rotated through the connecting pipe 41 as in the forward driving, so that the bicycle can be moved forward.

이때 페달축(10)은 역시계방향으로 회전을 하게되고 제1베벌기어(21)는 정방향 구동을 하게 되지만 정방향 클러치 베어링(22)에 의해 공회전을 하게 된다.At this time, the pedal shaft 10 is also rotated in the system direction and the first bevel gear 21 is driven in the forward direction, but is idle by the forward clutch bearing 22.

도6은 필요시 자전거를 뒤로 끌 경우의 동작 상태도를 나타낸 사시도이다. 이때는 먼저 캐리어(31)가 자유 회전가능하게끔 핸들에 별도 구성되어 있는 제어레버(도면 미 도시) 조작에 의해 캐리어 고정용핀(71)의 결속을 캐리어(31)에서 해제하여야 한다.6 is a perspective view showing an operation state diagram when the bicycle is pulled back if necessary. In this case, first, the binding of the carrier fixing pin 71 must be released from the carrier 31 by a control lever (not shown) which is separately configured on the handle to allow the carrier 31 to freely rotate.

후륜(도면 미도시됨)이 역회전을 하게되면 이것과 연결된 체인에 의해 스프라켓(42)이 역회전을 하게되며, 연결관(41), 제1베벌기어(21)등이 역방향으로 회전하게 된다.When the rear wheel (not shown in the drawing) is rotated in reverse, the sprocket 42 is reversed by the chain connected thereto, and the connecting pipe 41 and the first bevel gear 21 are rotated in the reverse direction. .

그러면 정방향 클러치 베어링(22)에 의해 페달축(10)도 역방향으로 회전을 하게 되며, 페달축(10)의 역방향 회전으로 이것과 연결된 좌측의 역방향클러치 베어링(24) 또한 역방향으로 회전을 전달하게 되므로 결과적으로 스플라켓(42), 페달축(10), 제1베벌기어(21), 제2베벌기어(32), 캐리어(31), 제3베벌기어(23)가 전체로 역방향으로 회전하게 된다.Then, the pedal shaft 10 is also rotated in the reverse direction by the forward clutch bearing 22, and the reverse clutch bearing 24 on the left side connected thereto by the reverse rotation of the pedal shaft 10 also transmits the rotation in the reverse direction. As a result, the sprocket 42, the pedal shaft 10, the first bevel gear 21, the second bevel gear 32, the carrier 31, and the third bevel gear 23 rotate in the reverse direction as a whole. .

그러므로 결국 일반 자전거와 같이 뒤로 끌수가 있는 것이다.Therefore, you can drag back like a normal bike.

이와같이 구성된 본 발명의 특성을 간추려 보면,In summary, the characteristics of the present invention configured as described above

페달축(10)의 정방향 구동시는 캐리어(31)의 고정 및 해제에 관계없이 전진 구동이 가능하며, 역방향 구동시는 캐리어 고정용 핀(71)에 의해 캐리어(31)의 회전을 제한하여 구동하게 되며, 뒤로 끌기를 할때는 캐리어의 고정용핀(71)을 해제하여 캐리어(31)가 회전가능하게 하여 사용하게 되는 것이다.In the forward driving of the pedal shaft 10, forward driving is possible regardless of the fixing and releasing of the carrier 31, and in the reverse driving, the rotation of the carrier 31 is limited by the carrier fixing pin 71. When the back is dragged, the carrier 31 is rotatable by releasing the fixing pin 71 of the carrier.

상기와 같은 구동특성으로 인한 본 발명의 바람직한 사용예로는, 평상시에는 캐리어 고정용핀(71)을 캐리어(31)에서 해제하여 캐리어(31)를 고정하지 않고 회전 가능하게 사용함으로써 통상의 자전거와 동일하게 사용하다가 역방향 구동시에만 제어래버(도면 미 도시)에 의해 캐리어(31)를 고정하여 사용하면 되는 것이다.As a preferred use example of the present invention due to the driving characteristics as described above, the carrier fixing pins 71 are normally released from the carrier 31 to be rotated without using the carrier 31 to be the same as a normal bicycle. The carrier 31 may be fixed and used by a control lever (not shown) only in the reverse driving mode.

도 7은 본 발명의 다른 실시예를 나타낸 측 단면도 사시도로서 페달축(10)의 정,역방향 회전력을 제1베벌기어(21)및 제3베벌기어(23)에 전달하는 동력 전달수단으로 일방향 동력전달장치인 래칫을 이용한 것을 나타낸 것이다.7 is a side cross-sectional perspective view showing another embodiment of the present invention as a power transmission means for transmitting the forward and reverse rotational force of the pedal shaft 10 to the first bevel gear 21 and the third bevel gear 23. It is shown using a ratchet as a delivery device.

도 8 및 도 9는 도7의 D-D 및 E-E 부분의 단면도로서 페달축(10)과 제 1베벌기어(21) 및 제3베벌기어(23)와의 사이에 일방향 동력전달장치인 래칫을 사용했을때의 동작상태를 나타낸 것이다.8 and 9 are cross-sectional views of the DD and EE portions of FIG. 7 when a ratchet as a one-way power transmission device is used between the pedal shaft 10 and the first bevel gear 21 and the third bevel gear 23. It shows the operation state of.

상기 래칫은 내주면이 키이(211)에 의해 페달축(10)과 축결속되고, 외주면은 일정간격으로 래칫홈부가 형성되어 있는 래칫기어(210)와, 베벌기어 내주면 2곳의 홈부위에 형성되어 있는 래칫돌기부(220)와의 결합에 의해 구성되며, 래칫돌기부(220)는 래칫돌기(220A), 복귀스프링(220C), 고정핀(220B)으로 이루어져 있으며, 이들 래칫은 제1베벌기어(21) 내주면에 설치되는 래칫은 정방향으로 동력을 전달할수 있게 설치되고, 제3베벌기어(23) 내주면에 설치되는 래칫은 역방향일때 동력을 전달할수 있도록 방향이 서로 반대로 구성된다.The ratchet has a ratchet gear 210 having an inner circumferential surface axially coupled to the pedal shaft 10 by a key 211, and an outer circumferential surface formed at a predetermined interval between the ratchet gear 210 and the groove portions of two inner peripheral surfaces of the bevel gear. The ratchet protrusion 220 is configured by coupling with the ratchet protrusion 220, and the ratchet protrusion 220 includes a ratchet protrusion 220A, a return spring 220C, and a fixing pin 220B, and the ratchet is a first bevel gear 21. The ratchet installed on the inner circumferential surface is installed to transmit power in the forward direction, and the ratchet installed on the inner circumferential surface of the third bevel gear 23 has the opposite directions so as to transmit power in the reverse direction.

이와같이 구성된 본 발명은 도8에서와 같이 페달축(10)을 정방향으로 구동하였을때는 키이(211)에 의해 축결속된 래칫기어(210)가 정방향 회전하게 되고, 이것은 다시 래칫홈부에 끼워진 래칫돌기(220A)에 의해 제1베벌기어(21)를 정회전시키게 되므로 상기 설명과 같이 연결관 (41)을 통해 스프라켓(42)을 구동하므로 자전거는 앞으로 전진할수 있게 된다.In the present invention configured as described above, when the pedal shaft 10 is driven in the forward direction as shown in FIG. 8, the ratchet gear 210 which is axially bound by the key 211 is rotated in the forward direction. Since the first bevel gear 21 is rotated forward by 220A, the sprocket 42 is driven through the connecting pipe 41 as described above, so that the bicycle can move forward.

상기 도면의 점선화살표 회전방향은 역방향구동시의 각부품의 회전방향을 나타낸 것이다.The rotation direction of the dotted arrow in the figure shows the rotation direction of each component in the reverse driving.

캐리어(31)가 회전하지 않게끔 캐리어고정핀(71)에 의해 고정된 상태에서 페달(10)을 역방향으로 구동하였을때는 도9에서와 같이 키이(211)에 의해 축결속된 래칫기어(210)가 역방향회전하게 되고, 이것은 다시 래칫홈부에 끼워진 래칫돌기(220A)에 의해 제3베벌기어(23)를 역회전 시키게 된다, 그러면 도7과 같이제3베벌기어(23)와 기어결속되어 있는 제2베벌기어(32)를 역방향으로 자전시키게 되고, 이것과 맞물려 있는 제1베벌기어(21)를 정회전 시키게 되므로 상기 설명과 같이 연결관 (41)을 통해 스프라켓(42)을 구동하므로 자전거는 앞으로 전진할수 있게 된다.When the pedal 10 is driven in the reverse direction while the carrier 31 is fixed by the carrier fixing pin 71 so that the carrier 31 does not rotate, the ratchet gear 210 that is axially bound by the key 211 as shown in FIG. Is rotated in the reverse direction, and this causes the third bevel gear 23 to be reversed by the ratchet protrusion 220A fitted to the ratchet groove portion. Then, as shown in FIG. 7, the third bevel gear 23 is gear-bound with the third bevel gear 23. Since the second bevel gear 32 is rotated in the reverse direction, and the first bevel gear 21 engaged with this is rotated forward, the sprocket 42 is driven through the connecting pipe 41 as described above. You can move forward.

상기 도 8 및 도 9 도면의 점선 화살표 회전 방향은 정방향 구동시의 각 부품의 회전방향을 나타낸 것이다.8 and 9 illustrate the rotation direction of each component during the forward driving.

이상과 같은 본 발명은 정방향구동 및 뒤로끌기는 통상의 자전거와 동일하게 사용할 수가 있으며, 역구동시에도 핸들에 취부되는 캐리어 조작레버를 간단히 조작하여 캐리어(31)를 고정함으로서 자전거를 앞으로 주행시킬수 있게 함으로서 다리근육의 균형적인 발달을 도모할수 있는 장치로서, 구조가 간단하여 부피를 적게 차지하므로 앞바퀴의 축하우징 내에 간단히 설치될 수 있고, 소음이 적은 잇점이 있다.The present invention as described above can be used in the same manner as a normal bicycle driving forward and backward, and by operating the carrier operating lever mounted on the handle at the time of reverse driving simply by fixing the carrier 31 to drive the bicycle forward As a device that can promote balanced development of leg muscles, the structure is simple and occupies a small volume, so it can be easily installed in the front housing celebratory housing and has the advantage of low noise.
