ABSTRACT:
A rope jumping device, including a rope having opposite ends, a platform and an elongated handle. The arm is rotatably mounted on the handle near one end thereof. An anchor is pivotally connected to the platform. One end of the rope is connected to the arm and the other end is connected to the anchor. The rope is of sufficient length such that a user, when standing on the platform, will be able to hold the handle above his or her head. Manipulation of the handle by rotation when the handle is elevated above the head of the user causes rotation of the arm, the rope and the anchor, with the rope describing a generally hyperbolic path above the pivotal connection of the anchor to the base. The arm is mounted on the handle for limited longitudinal movement relative to one end of the handle in addition to rotational mounting on the handle.
