<p>The object of this invention is to provide a motor-driven jumping apparatus having a two-cycle engine. In this apparatus, the two-cycle engine (100) compresses, ignites and explodes a gas mixture by the weight of a user, thus generating an expansion force for repeatedly and regularly bounding on a support surface. This jumping apparatus has a cylinder (110) with a piston (120). A piston rod (130) extends from the piston (120) to the outside of the cylinder (110), and is normally biased downward by a compression coil spring (132). A suction unit (140), an exhaust unit (150) and an ignition unit (160) are provided on the cylinder (110) for sucking, exhausting and igniting the gas mixture during operation of the two-cycle engine (100). A frame (200) is integrated with the cylinder (110), and has both a handle (210) and a foothold (220) for allowing a user to ride and control the jumping apparatus.</p> |
