Motorized drive for juvenile swing |
摘要 |
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.
