Abstract
A jump rope featuring, in various aspects, a soft cushion element attached to a cord to prevent the cord from striking the ground, thereby decreasing noise; and a grip at each end of the cord including a ring attached to the cord, the cord being adjustably threaded through the ring to form a loop which can be increased or decreased in size to change the operative length of the rope.

A jump rope comprising:
- a cord having a longitudinal axis,
- grips at the ends of said cord, and
- cushion element means attached to said cord intermediate said grips,
- said cushion element means comprising a multiplicity of soft finger means longitudinally and angularly positioned about said axis and each extending outwardly therefrom with the base thereof attached to said cord, whereby the operative diameter of said rope is increased by the length of said outwardly extending finger means, and
- said cushion element means extending sufficiently along said axis, so that when said cord is turned by said grips, said cushion element means prevents said cord from striking the ground, thereby decreasing the noise that would otherwise occur,
- wherein said cord comprises at least three strands, and said cushion element means comprises at least two elongated serrated pads with the direction of elongation extending along the axis of the cord and with each pad positioned in a respective interstice between said strands and entwined therewith and with said soft finger means being formed by the serrations of said serrated pads.
