본 고안은 사람의 체중에 의해 바퀴를 회전시킬 수 있도록 구성한 자전거의추진장치에 관한 것으로 좀더 구체적으로는 자전거의 후륜축에 관한 것으로 좀더 구체적으로는 자전거의 후륜측에 치차를 가진 두개의 프리휠(free wheel)을 설치하고 이들 프리휠이 새들(saddle) 하방에 연설된 승강간과 발판이 연설돈 승강간에 각각 맞물리도록 하여 각 승강간이 상호 교대로 승강하면서 후륜을 연속적으로 회전시킬 수 있도록 한 것이다.The present invention relates to a propulsion device of a bicycle configured to rotate a wheel according to the weight of a person. More specifically, the rear axle of a bicycle. More specifically, two freewheels having gears on the rear wheel side of a bicycle (free) The wheels were installed and these freewheels were fitted under the saddle and the footholds were engaged with the hoistway, respectively, so that the hoistways could rotate continuously and the rear wheels could be rotated continuously.
종래의 자전거, 예를들어 폐달을 회전시키거나 또는 폐달을 상ㆍ하로 구동시켜 후륜을 추진토록 구성된 자건거는 다리의 족답력과 굴신운동에 의해 후륜이 추진되도록 구성되어 있기 때문에 자전거의 추진속도나 자체 하중에 의해 많은 힘이 소요되었고, 따라서 어린이나 노약자들은 쉽게 탈 수 없는 결점이 있었다.Conventional bicycles, for example, bicycles configured to rotate the lungs or drive the rear wheels by driving the lungs up and down, so that the rear wheels are propelled by the stepping force of the legs and the flexion movement. The load required a lot of force, so children and the elderly had a flaw that could not be easily burned.
본 고안은 종래의 이와 같은 점에 착안하여 자전거을 탄 사람이 앉고 일어서는 단순한 동작에 의해 자전거를 연속적으로 추진할 수 있는 장치를 제공하기 위한 것인 바, 이를 첨부된 도면에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to provide a device that can continuously push the bicycle by a simple operation of the person sitting and standing on the bicycle in light of the conventional bar, which will be described in more detail by the accompanying drawings as follows. same.
첨부도면 제1도는 본 고안의 측단면도로서, 차체(1)의 뒷부분에 후륜(2)이 결합된 차축(3)과 연결편(5)이 끼워진 축(4)이 설치되어 있고, 차축(3)의 중앙부위에는 각각 다른 직경을 가지며 바깥둘레에는 치차가 형성된 프리휠(6)과 프리휠(7)이 설치되어 있다.1 is a side cross-sectional view of the present invention, in which a rear axle 3 is provided with an axle 3 to which a rear wheel 2 is coupled and an axle 4 into which a connecting piece 5 is fitted. The central portion of each has a different diameter and the outer circumference is provided with a freewheel (6) and a freewheel (7) is formed.
새들(8)의하방에는 승강간(9)이 부착되어 있고 이 승강간(9)에 형성된 치차는 프리휠(6)과 맞물려 있으며, 승강간(9)은 별도의 승강보조구(도시하지 않았음)에 의해 수직으로만 승강하면서 프리휠(6)을 회전시킬 수 있도록 되어 있다.Below the saddle 8 is a lifting platform 9 attached thereto, the gears formed in the lifting platform 9 mesh with the freewheel 6, and the lifting platform 9 is a separate lifting aid (not shown). It is possible to rotate the freewheel 6 while raising and lowering only vertically.
승강간(9)에는 축(4)에 끼워진 연결편(5)의 일단이 고정되어 있고 연결편(5)의 타단은 발판(11)을 가진 승강간(10)에 고정되어 승강간(9)(10)이 연결편(5)에 의해 상호 교대로 승강할 수 있도록 되어 있으며 승강간(10)도 역시 별도의 승강보조구(도시하지 않았음)에 의해 수직으로만 승강하면서 프리휠(7)을 회전시킬 수 있도록 되어 있다.One end of the connecting piece 5 fitted to the shaft 4 is fixed to the lifting piece 9, and the other end of the connecting piece 5 is fixed to the lifting piece 10 having the footrest 11, so that the lifting piece 9, 10 is fixed. ) Is allowed to elevate alternately by the connecting piece (5) and the lifting step 10 can also rotate the freewheel (7) while also lifting only vertically by a separate lifting aid (not shown). It is supposed to be.
도면중 설명되지 않은 부호 12는 전륜이고, 13은 핸들이다.Reference numeral 12, which is not described in the figure, is a front wheel, and 13 is a handle.
이와 같이 구성된 본 고안은 사람이 새들(8)에 앉으면 체중에 의해 새들(8)이 하강하게 되고 새들(8)이 하강하면 승강간(9)도 함께 하강하여 프리휠(6)을 시계방향으로 회전시키게 되므로 프리휠(6)의 회전력에 의해 차축(3)과 후륜(2)이 회전하게 된다. 이때 승강간(9)에 일단이 고정되어 있는 연결편(5)은 축(4)을 중심으로 회전하게 되고 연결편(5)의 회전에 의해 승강간(10)은 상승하면서 프리휠(7)을 반시계방향으로 회전시키게 되지만 각 프리휠(6)(7)은 일방향으로만 회전력이 전달되므로 반시계방향의 회전력은 차축(3)에 전달되지 않아 프리휠(7)은 공회전을 하게 되며, 따라서 후륜(2)은 프리휠(6)의 회전력에 의해서만 회전된다. 새들(8)이 하강하고 발판(11)과 결합된 승강간(10)이 상승된 상태에서 몸을 일으키며 발판(11)을 밟아주게 되면 전술한 작동과는 반대로 승강간(10)은 하강하면서 프리휠(7)을 시계방향으로 회전시키게 되고 연결편(5)에 의해 상승하는 승강간(9)은 프리휠(6)을 공회전시키면서 상승하게 되므로 프리휠(7)의 회전력만 차축(3)에 전달되어 후륜(2)이 회전하게 되며 상기와 같은 작동을 연속 반복적으로 행하여 자전거를 연속적으로 추진할 수 있게 된다.When the person sits on the birds 8, the present invention is constructed so that the birds 8 are lowered by the weight, and when the birds 8 descend, the lifting section 9 is also lowered to rotate the freewheel 6 clockwise. Since the axle 3 and the rear wheel 2 are rotated by the rotational force of the freewheel 6. At this time, the connecting piece 5 having one end fixed to the lifting leg 9 rotates about the axis 4, and the lifting leg 10 is raised by the rotation of the connecting piece 5, while the freewheel 7 is counterclockwise. Direction, but each freewheel (6) (7) is a rotational force is transmitted only in one direction, so the counterclockwise rotational force is not transmitted to the axle (3), the freewheel (7) is idling, so the rear wheel (2) Is rotated only by the rotational force of the freewheel 6. When the saddle 8 descends and the lift platform 10 coupled with the footrest 11 is raised, stepping on the footrest 11, the lifting platform 10 descends while freewheeling as opposed to the above-described operation. (7) is rotated in the clockwise direction and the lifting step (9) which is raised by the connecting piece (5) is raised while idling the freewheel (6), so that only the rotational force of the freewheel (7) is transmitted to the axle (3) and the rear wheel ( 2) is rotated and by repeatedly performing the above operation it is possible to continuously push the bicycle.
이와 같이 본 고안은 후륜(2)이 결합된 차축(3)에 두 개의 프리휠(6)(7)을 각각 설치하여 프리휠(6)은 새들(8) 하방의 승강간(9)과 또 프리휠(7)은 발판(11)에 결합된 승강간(10)과 각각 맞물리게 하고 이들 각 프리휠(6)(7)이 새들(8)과 발판(11)의 반복적인 하강운동 즉, 사람이 자전거를 탄 상태에서 앉았다 일어섰다 하는 단순한 동작에 의해 연속적으로 회전할 수 있게 되므로 누구나 쉽게 자전거를 추진할 수 있게 되고 따라서 어린이나 노약자 등도 쉽게 자전거를 탈 수 있는 효과가 있다.As such, the present invention provides two freewheels 6 and 7 respectively installed on the axle 3 to which the rear wheels 2 are coupled, so that the freewheels 6 are provided with the lifting section 9 and the freewheels below the saddle 8. 7) is engaged with the lifting platform 10 coupled to the footrest 11, respectively, and each of these freewheels 6,7 is a repetitive lowering motion of the saddle 8 and the footrest 11, i.e. a person rides a bicycle. Since it is possible to rotate continuously by a simple motion of sitting and standing in a state, anyone can easily push the bicycle, and thus children or the elderly can easily ride the bicycle.
