ABSTRACT:
Disclosed is a jumping device for exercise including an arc-shaped plate spring, a vertical member coupled to the plate spring, a footrest coupled to the vertical member while extending horizontally, a hinge lever hingably coupled to the footrest, a hoof lever hingably coupled to the hinge lever and fixedly mounted to the plate spring in an overlapping state, a shoe case serving as a shoe to be worn by a user, the shoe case being integrally coupled to the footrest while including a shoe bottom plate, and a U-shaped strip member serving as a connecting rod for connecting the footrest to the vertical member, the strip member having leg portions each fixedly mounted at a lower end thereof to an intermediate portion of the shoe bottom plate while extending upwardly and inclinedly toward an upper end thereof, and a connecting portion for connecting the leg portions, and a fitting member fixedly mounted to the connecting portion of the strip member at the rear of the strip member, the fitting member being fitted around the vertical member. The strip member has a function as a connecting rod adapted to maintain the shoe case in its horizontal state, thereby eliminating need for a separate connecting rod. In particular, the jumping device can be conveniently used by children without any danger of injury because no connecting rod is used.
