PURPOSE: A pedal-driven kick scooter is provided to allow a user to propel the kick scooter without kicking the ground because a gear is driven with the rotational motion converted from the reciprocating motion of pedals. CONSTITUTION: A pedal-driven kick scooter comprises a drive gear(46), a clutch gear, first and second connecting gears(62,64), a power transmission gear(66), and a rotating gear(70). The drive gear is formed on an end of a crank shaft(44) and coupled to an end of a link by a hinge. The crank shaft converts the reciprocating motion of pedals into the rotational motion. The clutch gear is engaged with the drive gear and selectively connected to one of first and second shift gears(52,54) to rotate the shift gear. The first and second connecting gears are respectively engaged with the first and second shift gears. The power transmission gear receives the torque of the first and second connecting gears through a connection shaft(60). The rotating gear transfers the torque of the power transmission gear through a rotary shaft(72) to a rear wheel(30). |
