THE ROLLER-SKI OF INLINE-BOARD

摘要

An inline board type roller ski is provided to move forward by itself by waveform movement through a caster mounted in a lower portion of a shaft by enabling a pair of shafts at mutually symmetrical conversion angle to move, maintain a steering unit in a vertical state during driving and in a folded state during portable or keeping state. An inline board type roller ski(100) includes the following units. Another side of a shaft is mutually and symmetrically rotated. A foot board(120) includes a support surface(121) in an upper portion and an inclination surface in a lower portion. The inclination surface is inclined in a direction opposite to a forward direction of the inline board type roller ski. A caster unit(130) is moved forward by itself by rotation motion of the shaft. A steering support unit connects a handle block(142) to a connecting groove(141a) rotatably and connects a handle connecting shaft extended upward to a connecting hole. A steering unit(150) includes a sub handle bar(153) vertically slidable in a main handle bar. A brake unit(170) controls caster rotation force of the caster unit through a handle(161) mounted in both ends.
