Abstract

An outdoor umbrella includes an umbrella frame, an awning element, and an operation system. The umbrella frame includes a supporting frame and an awning frame adapted to fold between an opened position and a closed position. The operation system includes an operational controller supported at the supporting frame, a pulley unit supported within the umbrella frame in a hidden manner; and an elongated controlling element running from the operational controller to the awning frame through the pulley unit and defining an operation length between the operational controller and the awning frame. When the operational controller is actuated to shorten the operation length of the controlling element, the awning frame is pivotally folded at the closed position. When the operational controller is actuated to extend the operation length of the controlling element, the awning frame is pivotally folded at the opened position.
