  • Patent number: 6645123
    Abstract: The present invention is for an apparatus which provides an automatic method for turning both ends of jump rope. Providing a hands free method for turning a jump rope eliminates the need for parents or other children to turn the rope manually. This allows children to enjoy jumping rope even while playing alone and prevents arguments over whose turn it is to twirl the rope when playing in a group. The automatic jump rope apparatus consists of a pair of poles which are spiked on the bottom and fit in weighted bases so that they provide stability on flat surfaces and can be removed from the bases and driven into the ground to provide stability on uneven surfaces. One pole holds one end of the rope and allows it to be turned as rotational force is applied to the other end of the rope by a spring loaded crank assembly located on the opposite pole. The user would simply crank the unit and then hit a release lever to enable the unit to rotate, thus swinging the jump rope between the two poles.
