ABSTRACT:
The present invention is related to a rectilinear sliding panel display used for displaying pictures and/or messages. A plurality of plate assemblies, each comprising a plurality of plates positioned on top of each other, are provided, wherein the assemblies are positioned adjacent to each other. The adjacent visible plates of the assemblies form the picture and/or message. Also provided are a plurality of links corresponding in number to the plurality of plates. The links are positioned behind the rear face of the plate assemblies, wherein each of the links is coupled to one corresponding plate in each of the plate assemblies. A drive means is provided for sequentially operating the links. The drive means comprises a plurality of stacked rings, each of the rings being coupled to one of the links. A shaft means is provided for sequentially engaging each of the rings and for rotating the ring in response to the rotation of the shaft means. The rotation of the shaft rotates one of the rings, thereby linearly moving the corresponding link. The corresponding plates then slide with respect to the other plates in the plate assemblies.
