<p>A louver display panel system comprising one or more display panels for receiving advertising or other material thereon, one or more support members to secure the display panels to a building, and at least one louver movement control means. The panels are rotationally secured and mounted to the support members and form a louver structure. The control means maintains the panels in a first position where they are in a plane generally parallel to the exterior face of the building until a wind load applied to the panels exceeds a pre-determined value, after which the control means permits the panels to at least partially rotate toward a second position that is generally parallel to the direction of the wind to reduce the wind load borne by the display panels. The control means returns the panels to their first position when the wind load drops below the pre-determined value.</p> |
