摘要： A swing assembly for a small child is provided. The swing assembly includes first and second upright swing support frames, with each support frame being formed from a pair of upstanding support members. A base member is provided for rigidly fixing the pair of upstanding support members side-by-side one another in substantially perpendicular relation to an underlying surface. A swing seat is provided as well as hangers connected to the seat for suspending the swing seat in the swing-receiving space. The hangers are pivotally connected to the upper portions of the spaced-apart pairs of upstanding support members so that the hangers and the swing seat pivot about an axis that extends between the pairs of upstanding support members during movement of the swing seat relative to the first and second swing support frames.
