发明名称 Rotational flagpole
摘要 Disclosed is a rotational flagpole pivotally mounted to a rigidly affixed base with a tongue and slot combination that enables the flagpoles to rotate around the pivot. The flagpole can also be locked in place to prevent rotation. The rotational flagpole thereby permits rotation of the top end of the flagpole to within a few feet of the ground in order to provide improved access to the top end for maintenance.
