Abstract
Abstract A baby crib having an automatic swinging apparatus includes a bed frame assembly supported on a base platform by flexible straps. The crib has an electric motor for swinging the rocker. Swinging reversal forces are reacted smoothly by tension springs which alternately store and release energy during each swing cycle so that the momentum of the swinging crib is overcome at each reversal of swinging movement.
