Abstract: An outdoor umbrella that closes automatically in high wind is disclosed. The wind causes the main support post of the umbrella to flex from the vertical dislodging a plunger from its weight bearing mounting on a rigid rod. The plunger is attached to an actuator rod extending upward within the support post. When the plunger is displaced the actuator rod is caused to move downward thereby activating a releasing ratchet which frees a shaft to rotate and the cable which holds the canopy to unwind. A hydraulic cylinder attached to one of the canopy ribs presses on the rib to close the canopy and maintain the canopy in closed orientation. As the canopy closes a reset mechanism is activated which resets the plunger onto the rigid rod. Once closed the canopy will remain closed until raised by manually rewinding the cable onto the shaft using a hand crank attached to the end of the shaft. A second ratchet assembly incorporated into the hand crank prevents the hand crank from spinning when the umbrella closes.
