Patent ID: 7509762

Claim:
A multi-sided display sign apparatus comprising: (a) a stationary frame; (b) a first plurality of elongated display sign elements mounted in a spaced relationship within said stationary frame; (c) a first means for mounting each of said first plurality of elongated display sign elements for rotation about a longitudinal axis thereof; (d) a first electrically operable drive means for rotating said first plurality of elongated display sign elements; (e) a movable frame; (f) a second plurality of elongated display sign elements mounted in a spaced relationship within said movable frame; (g) a second means for mounting each of said second plurality of elongated display sign elements for rotation about a longitudinal axis thereof; (h) a second electrically operable drive means for rotating said second plurality of elongated display sign elements; and (i) means disposed within and attached to said stationary frame and connected to said movable frame for laterally moving said movable frame and said second plurality of elongated display sign elements between a first position wherein said second plurality of elongated display sign elements are interposed with said first plurality of elongated display sign elements in a side-by-side arrangement and a second position wherein said second plurality of elongated display sign elements are laterally spaced from said first plurality of elongated display sign elements, said frame moving means including a quartet of drive assemblies each mounted adjacent a respective corner of each of said stationary and movable frames and having an electric motor rigidly attached to a predetermined portion of said stationary frame and having a horizontally disposed output shaft, a horizontally disposed drive screw connected to said output shaft of said electric motor, a bearing mount for rotateably mounting said drive screw, said bearing mount having a first flange extending outwardly therefrom and disposed in a vertical plane and at least a pair of apertures formed through said first flange, and a drive nut mounted for reciprocal linear motion on said drive screw, said drive nut having a second flange extending outwardly therefrom and disposed in a horizontal plane, said second flange directly connected to a predetermined portion of said movable frame.
