Abstract
A child motion apparatus includes an upright column defining a vertical axis, a carriage assembled with the upright column and including a swing shaft portion operable to rotate about a pivot axis, a swing arm affixed with the swing shaft portion, a first motor drive unit assembled with the carriage and having an output shaft, a drive transmission respectively connected with the output shaft and the swing shaft portion, a second motor drive unit assembled with the upright column, and an actuating mechanism respectively connected with the second motor drive unit and the carriage. The drive transmission can transfer an output drive provided by the first motor drive unit at the output shaft to the swing shaft portion to impart rotation to the driven swing arm. The actuating mechanism is drivable by the second motor drive unit to vertically move the carriage relative to the upright column.
