The display panel is rotationally secured to the support member and forms a louver structure. The louver movement control means maintains the display panel in a first position in a plane generally parallel to the exterior face of the building or structure until a wind load applied to the display panel exceeds a pre-determined value, after which the louver movement control means permits the display panel to rotate toward a second position generally parallel to the direction of the wind to reduce the wind load borne by the display panel. The louver movement control means returns the display panel to its first position when the wind load drops below said pre-determined value. ## Claims ### Claim 1 A louver display panel system comprising: one or more display panels for receiving advertising or other printed or graphic material thereon; one or more support members to secure said one or more display panels to a building or structure, said one or more display panels rotationally secured and mounted to said one or more support members and forming a louver structure; at least one louver movement control means, said louver movement control means maintaining said one or more display panels in a first position where they are in a plane generally parallel to the exterior face of the building or structure until a forwardly or rearwardly directed wind load applied to said one or more display panels exceeds a pre-determined value, after which said louver movement control means permits said one or more display 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 said one or more display panels, said louver movement control means returning said one or more display panels to said first position when the wind load drops below said pre-determined value, said louver movement control means comprising a pair of pneumatic or hydraulic cylinders mounted end to end with their pistons extending in opposite directions. ### Claim 2 (depends on 1) The louver display panel system as claimed in claim 1, wherein said louver movement control means permits rotational movement of said one or more display panels in a first direction when said one or more display panels are exposed to a pre-determined forwardly directed wind load, said louver movement control means permitting rotational movement of said one of more display panels in a second opposite direction when said one or more display panels are exposed to a pre-determined rearwardly directed wind load. ### Claim 3 (depends on 2) The louver display panel system as claimed in claim 2, wherein said one or more support members comprise one or more support posts, said one or more display panels being generally rectangular and mounted to said support posts through the use of pivot pins that intersect said one or more display panels at a position off-set from their central axis. ### Claim 4 (depends on 3) The louver display panel system as claimed in claim 3, including a rear guard or cage that is set-off from said one or more display panels to prevent access to said one or more display panels and to keep objects from contacting said one or more display panels upon the rotation of said panels. ### Claim 5 (depends on 4) The louver display panel system as claimed in claim 4, including a brace member positioned between each of said posts and said guard or cage to distribute wind loading borne by said panels to both said posts and said guard or cage. ### Claim 6 (depends on 5) The louver display panel system as claimed in claim 5, wherein said posts are support posts for securing between the floor and ceiling structure of a multi-story building. ### Claim 7 (depends on 1) The louver display panel system as claimed in claim 1, having two display panels mounted on a pair of support posts. ### Claim 8 (depends on 7) The louver display panel system as claimed in claim 7, wherein said display panels are positioned with one panel vertically above the other and the axis of rotation of said panels is generally horizontal. ### Claim 9 (depends on 1) The louver display panel system as claimed in claim 1, wherein said display panels are positioned with their axes of rotation in a generally vertical plane. ### Claim 10 (depends on 1) The louver display panel system as claimed in claim 1, wherein one of said pistons is mounted to a support post and the other of said pistons is mounted to a bracket secured to said display panel. ### Claim 11 A louver display panel system comprising: a generally rectangular display panel rotationally secured and mounted to a pair of support posts that are releasably securable to a building or structure, said display panel forming a louver structure; and a pair of louver movement control means associated with said display panel, each of said control means comprising a pair of pneumatic or hydraulic cylinders mounted end to end with their pistons extending in opposite directions and having one piston secured to one of said support posts and the other of said pistons secured to a bracket secured to said display panel, said pneumatic or hydraulic cylinders maintaining said display panel in a plane that is generally parallel to the exterior face of the building or structure until either a forwardly or rearwardly directed wind load is applied to said panel that exceeds a pre-determined value, after which said pneumatic or hydraulic cylinders permit said display panel to rotate to thereby reduce the wind load borne by said display panel, said pneumatic or hydraulic cylinders returning said display panel to its position where it is generally parallel to the exterior face of the building or structure when said wind load drops below said pre-determined value. ### Claim 12 A louver display panel system comprising: a display panel rotationally secured and mounted to at least one support member, and at least one louver movement control means associated with said display panel, said control means comprising a pair of pneumatic or hydraulic cylinders mounted end to end with their pistons extending in opposite directions and having one piston secured to said at least one support member and the other of said pistons secured to said display panel, said pneumatic or hydraulic cylinders maintaining said display panel in a plane that is generally vertical until either a forwardly or rearwardly directed wind load is applied to said panel that exceeds a pre-determined value, after which said pneumatic or hydraulic cylinders permit said display panel to rotate about said at least one support member away from its generally vertical position to thereby reduce the wind load borne by said display panel, said pneumatic or hydraulic cylinders returning said display panel to its generally vertical position when said wind load drops below said pre-determined value.
