ABSTRACT:
A children's swing has an elongated beam with opposite ends and a mid portion providing a seating platform for at least two children. Pivotally attached to the opposite ends of the beam are a pair of rigid rockers, each rocker having an upper end defining hand grips and a lower end defining a foot rest. To use the rocker, the children sit on the beam back to back with their hands and feet on the hand grips and foot rests of the rockers in front of them. When the children rock the rockers in synchronism, the swing will swing to and fro with ever increasing amplitude due to the inertia of the children's limbs and changes in the included angles between the rockers and the beam.
