A swing apparatus comprises a support stand, a swing supported with
respect to the support stand to oscillate back and forth along a swing
arc about a pivot axis, and a drive assembly that operates to oscillate
the swing. Various components of the drive assembly are coupled to the
swing to oscillate therewith about the pivot axis. The drive assembly has
a pair of drive members that periodically engage portions of the support
stand resulting in forces being imparted on the swing to move the swing.
