ABSTRACT:
A swing includes a swing frame, a seat member and a pair of generally C-shaped coupling units. The swing frame includes left and right upright side frames and a horizontal connecting rod which interconnects top ends of the side frames. The seat member is disposed between the side frames and has a pair of upwardly extending swing arms, each of which has a distal top end formed with an inverted U-shaped hook that opens downwardly toward the connecting rod. The coupling units are clamped spacedly and fittingly on the connecting rod. The hooks on the swing arms of the seat member engage slidably and respectively the coupling units on the connecting rod to permit forward and rearward swinging movement of the seat member relative to the connecting rod. The coupling units prevent direct contact between the hooks on the swing arms and the connecting rod to minimize wearing between the hooks and the connecting rod and to reduce noise that is generated when the seat member swings.
