ABSTRACT:
An umbrella supported by a mast located alongside the umbrella canopy. The umbrella canopy includes a radial arm connected to an element slidably mounted along the mast. A brace pivotably attaches to the arm and extends to the top of the mast. A flexible line extends from a winder within the mast, over a fixed pulley located at the top of a mast, a second pulley mounted on the sliding element, and then travels through the arm and around a third pulley located at the central region of the umbrella. This line operates the opening mechanism of the umbrella, and also selectively moves the slider element along the mast to adjust the tilt of the canopy assembly.
