본 발명은 시소형 어린이 자전거에 관한 것으로서, 특히 어린이용 자전거의 플레임에 지그재그형 링크에 의해 레버크랭크장치로 연결된 시소기판과 시소형 핸들에 의하여 후륜구동축에 장착된 레칫장치의 구동으로 전전운동이나 또는 정지상태에서 운동할 수 있는 시소형 승마식 자전거에 관한 것이다.The present invention relates to a seesaw-type children's bicycle, and in particular, the flame of the children's bicycle by the zigzag-shaped link by the lever crank device and the seesaw substrate connected by the seesaw-type handle to the rear wheel drive shaft driven by the pre-movement movement or The present invention relates to a seesaw riding bicycle capable of exercising in a stationary state.

종래 어린어용 자전거로는 페달을 밟아서 전진하거나 바퀴가 없이 고정시킨 상태로 패달을 밟아서 전진하는 흉내를 내면서 운동을하거나 승마형으로 만들어 스피링의 탄발력을 이용하여 상하나 전후로 탄력적으로 움직이게 하여 승마감을 가지면서 운동하도록 된 것이 있으니, 전진하면서 자전거겸 승마감을 갖게 시소형으로 자전거의 전후로 움직이게 된 어린이 자전거나 어른자전거는 없었다.Conventionally, for young children's bicycles, they move forward or backward by using the elasticity of the springs to make movements while riding or imitating by stepping on the pedals or stepping on the pedals in a fixed state without wheels. There was no children's bicycle or adult bicycle that moved to the front and back of the bicycle with the seesaw type as it moved forward.

본원은 이런점에 착안하여 전진하거나 정지된 상태에서 자전거로서의 역할을 하면서 시소형으로 전후로 시소운동을 하게 하여 승마감을 주므로써 어린이에게 운동겸 놀이로서의 즐거움을 만끽하게 하기 위한 자전거를 제공코저하는 것으로서 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.With this in mind, we provide a bicycle for children to enjoy the fun of exercise and play by giving them a riding experience by playing the seesaw exercise forward and backward in a seesaw form while acting as a bicycle in a forward or stationary state. This will be described in detail with reference to the accompanying drawings.

전방핸들부(3), 중앙자체(5), 후방플레임(7) 및 후륜구동축(9)으로 구성되는 어린이 자전거에 있어서, 후륜구동축(9)을 양분하여 그 중앙에 크랭크축(11)을 레칫장치(12)로 연결하고 상기 크랭크축(11)의 양측중앙은 직선링크(13)와 지그재그링크부(14)로 각각 차체(5) 및 시소기판(20) 양측에 회동되게 측착하며, 상기 시소기판(20)은 그 중앙이 차체(5) 중앙의 양 지지대(21)에 축착되어 전후로 시소식으로 작동되게 하고, 상기 핸들부(3)의 핸들(3a)은 핸들축(3b)을 중심으로 전후로 왕복운동하게 하며, 상기 레칫장치(12)는 후륜구동축(9)의 내측축단에 일체로 형성된 레칫휠(30)과 크랭크축(11)단에 일체로되어 내측에 클릭이 형성된 클릭휠(31)로 구성하고, 상기 직선링크(13)는 그 일측이 크랭크축(11)과 회동고리(15)로 회동가능토록 연결하며 타측은 시소기판(20)의 후단 일측면의 회전축(16)에 축착하고, 상기 지그재그링크(14)는 하측레버링크(17), 중앙 삼각링크(18) 및 상측 레버링크(19)가 차례로 축착된 것으로 구성하며 하측레버링크(17)의 하단부는 크랭크축(11)의 상기 직선링크(13)와 반대측에 회동고리(15')로 축착하며, 상측 레버링크(19)의 상단은 시소기판(20) 전면의 상기 직선링크(13)과 반대측 회전축(16')에 축착하되, 상기 삼각링크(18)의 중심축(22')은 차제(5)의 중심에 하향 고정된 하지지대(22)의 단부에 축착함을 특징으로 한 것이다.In a child bicycle composed of a front handle part (3), a central body (5), a rear frame (7) and a rear wheel drive shaft (9), the rear wheel drive shaft (9) is bisected and the crankshaft (11) is centered in the center thereof. Connected to the device 12 and the centers of both sides of the crankshaft 11 are rotated on both sides of the vehicle body 5 and the seesaw substrate 20 by the linear link 13 and the zigzag link unit 14, respectively. The substrate 20 has its center fixed to both supports 21 at the center of the vehicle body 5 so as to be actuated back and forth, and the handle 3a of the handle portion 3 is centered on the handle shaft 3b. To reciprocate back and forth, the ratchet device 12 is a click wheel 31 is formed integrally with the end of the ratchet wheel 30 and the crankshaft (11) integrally formed on the inner shaft end of the rear wheel drive shaft (9) click formed on the inside The linear link 13 has one side connected to the crankshaft 11 and the pivot ring 15 so as to be rotatable, and the other side is the rear end of the seesaw substrate 20. It is in contact with the rotating shaft 16 of the side, the zigzag link 14 is composed of the lower lever link 17, the central triangular link 18 and the upper lever link 19 is condensed in turn and the lower lever link 17 The lower end of the crankshaft 11 on the opposite side of the linear link 13 on the rotation ring 15 ', and the upper end of the upper lever link (19) is a linear link 13 in front of the seesaw substrate 20 And a central axis 22 'of the triangular link 18 is affixed to an end portion of the base plate 22 fixed downward to the center of the vehicle 5, and is fixed to the opposite rotation axis 16'. .

미설명부호 50은 스프링, 51은 차륜이다.Reference numeral 50 is a spring, 51 is a wheel.

이상과 같이 구성되는 본 발명 시소형 어린이 자전거는 운전 및 놀이시에 시소기판(20)에 적절한 형태의 안장을 씌워서 승차하여 핸들(3a)을 잡고 노젖듯이 앞뒤로 전후진하게 되면 핸들(3a)이 핸들축(3b)에 의하여 전후로 회동되게 되고, 스프링(50)을 핸들축(3b) 아래의 내측에 탄설할 경우에는 스프링(50)의 탄발력에 의하여 핸들(3a)의 전후진 작동이 휠씬 좋게 될 수도 있으며, 이와 같이 핸들(3a)의 전후진 작동에 따라 승차한 어린이의 몸이 전후로 움직이면서 시소기판(20)을 전후방으로 시소운동을 시키기되며 이에따라 시소기판(20) 전방일측의 회전축(16')에 축착된 상측 레버링크(19)를 비롯한 지그재그링크부(14)와 시소기판(20) 후방의 타측의 회전축(16)에 축착된 직선링크(13)의 크랭크 작동에 의하여 차체(5)의 후방크랭크축(11)이 교차 회동하면서 레칫장치(12)에 의해 차륜의 후륜구동측(9)을 회전시켜 전진하게 하되 핸들(3a)과 시소기판(20)의 시소작동이 계속되는 동안 클릭과 레칫의 원리에 의하여 크랭크축(11)이 뒤로 회전시에는 크릭장치(12)가 공회전하게 되고 앞으로 회전시에만 클릭이 레칫에 걸려 후륜구동축(9)을 몰고 회전시켜 차륜을 회전시키게 되므로 전진을 계속할 수가 있고, 만약 제자리에서 운코져 할때는 시소운동 각도를 크게 하면 크랭크 축의 레칫장치(12)가 뒤로만 계속 공회전되어 정지된 상태로 시소운동이 가능하게 된다.When the seesaw-type children's bicycle of the present invention configured as described above rides on the seesaw substrate 20 while driving and play, the handle 3a moves forwards and backwards back and forth like a paddle while holding the handle 3a. It is rotated back and forth by (3b), and when the spring 50 is installed on the inner side under the handle shaft 3b, the forward and backward operation of the handle 3a may be much better due to the spring force of the spring 50. In this way, according to the forward and backward operation of the handle (3a), the child's body is moved back and forth while the seesaw substrate 20 is moved forward and backward accordingly, according to the rotating shaft (16 ') of one side in front of the seesaw substrate 20 Rear crank of the vehicle body 5 by cranking of the zigzag link portion 14 including the upper lever link 19 and the linear link 13 fixed to the rotary shaft 16 on the other side behind the seesaw substrate 20. Retracting the shaft 11 while rotating (12) rotates the rear wheel drive side 9 of the wheel to move forward, while the crankshaft 11 is rotated backward by the click and the ratchet principle while the seesaw operation of the handle 3a and the seesaw substrate 20 continues. When the creek device 12 is idling and clicks only on the forward rotation, the click is applied to the ratchet and the rear wheel drive shaft 9 is driven and rotated so that the wheel can be rotated, so that the forward movement can be continued. If it is enlarged, the ratchet device 12 of the crankshaft continues to be idled back only and the seesaw movement is possible in the stopped state.

이상과 같은 구성과 작용을 하는 본 발명시소형 어린이 자전거는 패달이 없이 제자리에서나 전진하면서 승마감을 갖고 운동 및 놀이를 할 수 있어서 매우 편리하고 유용한 발명이다.The children's bicycle according to the present invention having the configuration and function as described above is very convenient and useful because it can move and play with a feeling of riding while moving forward or in place without a pedal.
