ABSTRACT:
A rocking cradle is provided which allows for a hanging cradle contained within a supporting frame to be aided in its cyclical transverse displacement by magnetic attraction and repelling forces. Central magnets are mounted on the hanging cradle and are attracted and repelled by a pair of magnets mounted on the supporting frame with one of the magnets being fixed to the supporting frame and the other magnet being rotatively displaceable with respect to the first magnet. Transverse displacement of the hanging cradle causes pivoting of one of the magnets on the supporting frame which then allows a repelling force from the stationary magnet to act against the magnets mounted on the hanging cradle to displace the hanging cradle away from the magnets on the supporting frame.
