KICK BOARD WITH SELF-GENERATING SYSTEM

摘要

PURPOSE: A kick board with self-generating system is provided, in which wheels of the kick board are driven by a simple repeated stepping-on action performed by a user, to thereby achieve an improved user convenience and economical advantage. CONSTITUTION: A kick board comprises a foot step(12) having an intermediate portion hinge-coupled onto a frame(13) such that the foot step is movable in a seesaw-like manner; a combination of wires(15a,15b) and ratchets(16a,16b) which is pulled in forward or backward direction in accordance with the seesaw motion of the foot step so as to transmit a rotation force in one direction; four rollers(24) for guiding advancing motion of wires; a driving shaft(17) rotating along with ratchets so as to generate a driving force; and a chain/gear transmission unit for transmitting power from the driving shaft to a rear wheel(14). The chain/gear transmission unit includes a driving sprocket(18) mounted to the driving shaft; a slave gear(19) mounted to the shaft of the rear wheel; a transmission gear(21) arranged to be engaged with the slave gear, and a transmission sprocket(22) connected to the driving sprocket through a chain(20), wherein the transmission gear and transmission sprocket are integrated into a single unit.
