A remotely or manually actuated electrically operated umbrella for use with larger canopies in outdoor settings like restaurants. The umbrella uses a gear and chain drive system to urge upward a traveling rod that in turn actuates a bracket to open and close the spokes of the umbrella. The rod is controlled by movements of a pulley turned by a motor. Two actuator pieces in connection with the pulley will contact "up" and "down" switches in order to automatically cut off the motor once the canopy has been closed or opened as the case may be.
