ABSTRACT:
A connector for a swing fixed on a frame rod and a swing arm of a swing includes a bearing, two protective covers and a connecting member which has a rectangular horizontal hollow portion for the frame rod to extend therein, and two vertical parallel ears extending down from the horizontal portion. The bearing is sandwiched within round portions of the two covers placed between the two ears and pivotally connected with a pivot pin passing through the ears, the round portions of the covers and the bearing. Each cover has a lower rectangular portion extending down from the round portion to fit around and secured with an upper end of a swing arm so that the swing arm may swing together about the covers with the pivot pin. Thus the connectors permit the swing arms to swing smoothly with little friction, thereby lessening wear of the components.
