Patent abstract
An adjustable offset umbrella has a generally vertical main pole and a sliding member slidably mounted to the main pole. The sliding member includes a locking mechanism for securing it at a desired location along the main pole. One end of an arm is associated with the sliding member, and the other end supports an umbrella canopy. A winding mechanism is associated with the sliding member and moves with it. A line extends from the winding mechanism to the umbrella canopy. Operating the winding mechanism opens and closes the umbrella canopy, and moving the sliding member up or down the main pole adjusts the angle of the canopy with respect to the main pole.
