Problems solved by technology

Unfortunately, it is difficult to reach the platform and turn off the switch while jumping rope.
Additionally, when in the vertical mode, it is difficult to turn on the motorized hub without getting whipped by the rope and adjoining crank arm.
Wireless transmitters add to the cost of the product and are susceptible to damage, thereby rending the apparatus inoperative.
Unfortunately, the user had no indication of when the motor was to start or end.

Embodiment Construction

[0020] Disclosed is an apparatus that moves a jumping element. The apparatus includes a motorized hub that is attached to a housing. The hub can rotate a jumping element, such as a jump rope, about a horizontal axis and / or a vertical axis. The hub is connected to a motor that is controlled by a timer. A player can select a time interval that establishes the activation time of the motor. The apparatus includes an indicator that may provide an indication of the time interval. The indicator may be an LED that indicates the numerical value of the time interval. The apparatus may also have an indicator that provides an indication of when the motor is to be activated, so that the player can be in position when the hub begins to rotate the rope.

[0021] Referring to the drawings more particularly by reference numbers, FIGS. 1 and 2 show an apparatus 10 that can swing a jumping element 12. The jumping element 12 may be constructed as a jump rope. The apparatus 10 includes a hub platform 14 t...

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an apparatus that can automatically rotate a jump rope. [0003] 2. Prior Art [0004] U.S. Pat. No. 4,739,985 issued to Rudell et al., discloses a motorized unit that can automatically rotate a jump rope. The motorized unit includes a motorized rotating hub that can be coupled to one end of a jump rope. The hub can be coupled to a pedestal so that the jump rope can rotate about a horizontal axis. The other end of the jump rope can be attached to a post or other stationary object. The apparatus allows the players to “jump rope” without manually swinging the rope. The apparatus also has a vertical mode wherein a hub platform is laid on the ground and the rope swings about a vertical axis. A player(s) then jumps over the swinging rope. [0005] The Rudell motorized unit has an on / off switch located on the hub platform. Unfortunately, it is difficult to reach the platform and turn off the swi...
