Abstract
A portable collapsible ventilator that is used to direct air currents into a boat hatch, recreational vehicle vent, or other opening in an enclosed space while, at the same time shielding that opening from the intrusion of rain and direct sunlight. The ventilator has a frame of hinged, flexible rods covered with a water repellent fabric with an opening at one end. The ventilator is erected into a freestanding unit by pushing down on the hinge point of the flexible rods and locking them in position with a locking mechanism to form a semi-circular shape. A rod is inserted between the front and center hinge points to extend the open end of the device forward into a rain and sun shielding position. The ventilator is then positioned over the opening to be ventilated and secured in place with attached shock cords. When not in use, the ventilator is collapsed into an elongated shape with the flexible rods aligned and the cover folded around them to enable insertion into a storage bag.
