Abstract: The jump rope device is constructed with a pair of stations disposed in mirror-image facing relation and a pair of ropes which are connected between rotating arms of each station. Each station employs a stepper motor to rotate the radially disposed arms as well as a transmission for rotating the arms in an out-of-phase relation to create a double dutch effect. The end of each rope is secured to a cord which is wound about a rotatable drum within each radial arm so that the length of exposed rope may be adjusted to a user. Should a user step on a rope, the resulting tension in the rope and cord effects an unwinding of the cord from the drum thereby allowing the rope to break away from the arm of the station.

At a handle end of the body, a clothesline tightener or foreshortener is used to clasp the handle-confined portion of the rope to prevent its movement through the body, however by withdrawal of the hollow shaft of the clothesline tightener, the rope is unclasped and can freely be drawn out of a pay out end of the handle, to lengthen the ball-tethered portion thereof, or drawn out of the handle end to foreshorten the ball-tethered portion thereof. The clothesline tightener is slidably and snugly held in the central bore of the body at the handle end thereof.

Abstract: A combination dumbbell and jump rope with interchangeable weight units is disclosed. Various weights may be quickly and easily attached or detached from the handles by pushing a button on the end of the weight unit. When pushed, the button releases ball bearings that lock the weight unit into grooves on the handle. The jump rope length is easily adjustable to accommodate each individual user by retracting a portion of the rope inside the hollow rope handles. Retraction is accomplished by the release of a variable-length clamping mechanism. When closed, the clamping mechanism presses ball bearings against the jump rope cable to hold it firmly in place. When released, the rope may move freely within a jump rope cable guide for length adjustment.

Abstract: A jump rope has a spindle rod with two off-set of center parallel cord receiving holes running through its entire length spins freely within a grip handle allowing the cord to rotate free of friction that would cause it to twist and deteriorate. The off-set holes act as a crank mechanism allowing for more efficient cord rotation energy transfer, provide a place to store cord ends (means of length adjustment), and they allow for use of two ropes, and also could be used as a place to mount end caps. There are several cord length and configuration adjustment embodiments disclosed. One adjustment is by frictionally clamping the cord in a notch in an end cap. This feature stabilizes the cord at a desired length and also sets the cord off at about a 90 degree angle from the handles which, by acting as a crank, allows for more efficient and effective use of cord rotation energy. Another adjustment feature works by simply inserting excess cord length in the empty off-set spindle rod holes.
