ABSTRACT:
There is disclosed a power unit for twirling a jump rope about a substantially horizontal axis, as in conventional rope jumping, or about a vertical axis to provide an entirely new variation of the game. The power unit includes a stand with a vertical standard which supports a motorized drive with an output shaft on which is mounted a crank element. One end of a jump rope is attached to the crank element, which twirls the jump rope. The opposite end of the jump rope is secured to a stationary support, e.g., fence post, side of a building, etc. The power unit can also be removed from the vertical standard and seated in a recess in the base of the stand with the drive shaft vertically oriented, whereby the crank element is rotationally driven about a vertical axis. A short rope is secured to the crank element and a weighted element such as a foam plastic ball is secured to its free end. The players jump the rope as it swung around in a horizontal arc of rotation, thereby providing a new variation of the game.
