Abstract: A system for installing and maintaining a display on a structure. The system includes at least one guide system having a pair of guide rails that have a first end accessible from the roofing surface of the structure and a second end attached to the side exterior wall of the structure. The guide rails each define a track that is designed for sliding receipt of guide pins disposed on a bottom side of a frame member. The guide pins are engaged within the track of each of the guide rails and remain engaged within the track of the guide rails such that the frame member can be slidingly positioned on the first end of the guide rails or, in a second position where the frame member is positioned on the second end of the guide rails. A selected display or sign is attached to a top side of the frame member.

Abstract: A variable display device for selectively displaying messages on or adjacent doors to hospital rooms, hotel and motel rooms, offices, conference rooms and the like to communicate such messages to the viewer. The device includes a frame member that is rotatably coupled to a display member movable to change the message appearing in a window of the frame member. In particular, the display member comprises a rotatable disk mounted to a shaft or stud adapted to pivot about an axis. Various display elements are carried on the face of the disk. The display elements take the form of messages to be viewed individually through the window. A knob is preferably mounted at the outermost end of the shaft of stud, adjacent the outer surface of the front panel. Rotating the knob rotates the disk and therefore changes the display element viewed through the window.
