Patent Images

1. A device for successively displaying a plurality of images, comprising:

  • (A) a plurality N of overlying flexible panels where N is at least 3, each of said panels defining a longitudinal series of flexible slats and louvers between said slats, said slats being longitudinally longer than said louvers, each of said slats of all underlying panels being interleaved longitudinally through said louvers of all overlying panels, said slats of each panel cooperatively defining one of said plurality of images, each of said slats of an overlying panel being laterally narrower than said slats of all underlying panels;

    each of said panels being a composite of two overlying flexible sheets marginally sealed together along the longitudinal edges thereof, each of said sheets defining a longitudinal series of flexible slats and windows between said slats, said slats being longitudinally longer than said windows, each of said slats of the underlying sheet being interleaved longitudinally through said windows of the overlying sheet to divide each window of the overlying sheet into two louvers, said slats of each sheet defining a partial one of a plurality of images and the slats of both sheets of a panel defining at least a full one of said plurality of images, each of said slats of the overlying sheet being laterally narrower than said slats of the underlying sheet; and

    (B) means for moving in turn each of a subset N-1 of said plurality of panels a length greater than the length of a louver such that movement of a given panel in one longitudinal direction exposes the slats of an adjacently overlying panel and conceals the slats of the given panel underneath the slats of an underlying panel, and movement of said given panel in the opposite longitudinal direction exposes the slats of said given panel and conceals the slats of an adjacently overlying panel under the slats of said given panel.
