Abstract

어린이용 자전거의 안장부를 시소형(20)으로 만들고 핸들부(3)도 시소형으로 하되 차체(5)와 시소기판(20)의 양측에 지그재그형 링크부(14)와 직선링크(13)을 연결하여 이 링크들을 후륜구동축(9)의 중앙에 레칫장치(12)로 장착한 크랭크축(11)의 양측중앙에 연결시키고 크랭크 작용과 레칫기어작용에 의하여 자전거가 시소운동을 하면서 전진하거나 제자리에서 시소운동을 할 수 있게 한 것으로서 어린이가 패달을 밟지 않고도 시소운동으로 승마감을 느끼면서 운동 및 놀이를 할 수 있는 시소형 어린이 자전거이다.The saddle of the children's bicycle to the seesaw type 20 and the handle portion (3) is also a seesaw type, the zigzag-shaped link portion 14 and the straight link (13) on both sides of the body 5 and the seesaw substrate 20 Connect these links to the centers of both sides of the crankshaft 11 equipped with the ratchet device 12 in the center of the rear wheel drive shaft 9, and move the bicycle forward or move in place by the crank action and the ratchet gear action. It is a seesaw exercise that allows children to see and exercise without having to step on the pedals.
