Claim:
A rotational movement apparatus comprising: a platform, said platform having a central point at which said platform rotates, said platform having an outer edge; said central point defining a central axis extending therethrough about which said platform rotates; said platform defining a first radius line extending from the central point to the outer edge; a rod connected to said platform and extending downward from the central point; an arm connected to the platform at a connection point spaced apart from the first radius line; said arm having a first portion extending from the connection point with said platform; said first portion of said arm ending at an elbow where said first portion of said arm connects to a second portion of said arm; said second portion of said arm is positioned to overlap the first radius line and extend upwards from the platform at a predetermined angle towards the central axis; a thrust bearing positioned above the platform in a manner so that a center of the thrust bearing is in alignment with the central point of the platform, said thrust bearing connected to said second portion of said arm; and, wherein said thrust bearing is positioned so that when a predetermined force pulls the thrust bearing upward along the central axis, the thrust bearing pulls the arm causing the platform to rotate.
