<p>: A support is provided for a person to sit on the rocking device to achieve a stable, but pleasing, motion. Front and rear leg pairs are provided for elevating the support. Corresponding front and rear arcuate rocker members are provided for rotating on a surface. The rotating motion is converted to a rocking motion by eccentrically and rotatably mounting the legs outboard of the center of rotation of the rocker members. Further rocking action is obtained by rotatably mounting the front or rear leg pairs to the support. Rotation of the rocker members is synchronized by rotating tie rods mounted along radials from the rotation centers for said rocker members.</p> |
