Power unit for rope jumping

A power unit for twirling a jumping element which comprises:

• a. a pedestal stand having a vertical standard mounted on a pedestal base;
• b. a power unit having a housing removably received on the upper end of said vertical standard and containing a power unit having a drive motor and output shaft;
• c. a crank element mounted on said output shaft of said power unit and mechanically coupled to said power unit;
• d. attachment means to secure a jumping element to an eccentric position on said crank element;
• and
• e. a horizontal recess in said pedestal base conforming to the exterior dimensions of said housing to removably receive said power unit with said crank element oriented for rotation about a vertical axis.

A power unit for a jumping game for players to jump a jumping element rotating in a horizontal plane, which comprises:

• a. a power unit having a housing for resting on a floor and including an electrical drive motor with an output shaft and an electrical power supply and on/off power control switches in circuit between said power supply and said drive motor mounted within said housing;
• b. a rotationally driven crank element for rotation about a vertical axis;
• and having a central hub having a transverse slot mounted on said output shaft of said power unit exteriorly of said housing, and a crank arm yieldingly mounted in the transverse slot of said hub by means permitting the substantially instantaneous detachment of said arm upon impact, and having a laterally extending arm;
• c. a jump rope which distally supports a weight and, at its opposite end, being attached to said extending arm to be swung in a horizontal arc by said power unit, whereby players can position themselves around said power unit and jump over the jump rope as it rotates;
• and
• d. a tether cord with one end thereof attached to one of said on/off switches within said housing and having a length greater than that of said crank element and said jump rope so that the opposite end thereof can be extended beyond the circle of rotation of said jump rope.
