Room Access Control System with Barrier Arm Having Downwardly Extending Fan Assembly

A room access control system comprising:

• a base assembly attachable to a wall or door jamb adjacent a door opening to a room;
• an arm having a first end pivotally mounted with respect to the base assembly at a stationary pivot point relative to the base for rotation about a pivot axis, the arm also having a second end;
• wherein the arm is positionable in a first undeployed position where the arm is generally vertical and the second end of the arm points downwardly;
• wherein the arm is pivotable from the first undeployed position, upwardly to a second, generally horizontal deployed position, where the arm extends at least partially across the door opening;
• wherein a fan assembly is attached to the arm, the fan assembly including a plurality of fan blades;
• wherein each of the fan blades has a first end that is pivotally mounted to the arm;
• wherein each of the fan blades has a second end that is attached to, and movable with respect to, an adjacent fan blade;
• wherein when the arm is in the first undeployed position, each of the plurality of fan blades is in a generally vertical position beneath the arm;
• and
• wherein the arm is in the second, generally horizontal deployed position, the plurality of fan blades extend beneath the arm in a fanned out pattern with the second end of a first fan blade of the plurality of fan blades attached to the arm, and a last fan blade of the plurality of fan blades positioned in a generally vertical position.
