Abstract

The jump rope device employs DC motors to rotate two ropes and a dual closed loop control system is used to synchronize the turning movements of the two ropes. An infrared beam is used to monitor the use of the machine by a user. Each motor housing is mounted on a tripod support which can be collapsed for ease of transportation and storage. A floor mat with sensors may be employed for various exercises.

Claims9

Dependent claims

A jump rope device comprising

a pair of stations disposed in mirror-image facing relation to each other, each station having a pair of rotatable mechanisms for receiving and turning a pair of ropes in opposite directions to each other and a pair of motors for rotating said mechanisms;
synchronization means in each station for synchronizing the rotation of said rotatable mechanisms;
and
electronic means in each station for controlling the speed of rotation of each rotatable mechanism.
