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. Cord length adjustments can also be made with the use of cord clamps. The cord can also be adjusted lengthwise and/or angled in several configurations by inserting it through holes provided for this purpose in both end caps of both handles.
