Abstract
In one or more arrangements, an umbrella system includes a support pole connected to a rotating tube positioned around a center tube that extends between the support pole and a upper hub that is connected to an umbrella frame. The rotating tube has one or more helical grooves therein that are engaged by a lower hub which is connected to the umbrella frame. As the rotating tube is rotated, the lower hub is driven along the length of the rotating tube, thereby opening and closing the umbrella frame. In one or more arrangements, the system includes a rotational lock assembly configured to prevent rotation of the rotating tube when locked and permit rotation of the rotating tube when unlocked. In one or more arrangements, the system includes a counterbalance assembly that provides a counterbalance force positioned within a upper hub of the umbrella frame.
