ADVERTISEMENT DEVICE Russian patent published in 2006 - IPC G09F11/02 

FIELD: advertising.

SUBSTANCE: advertising device contains three-edged indicator elements, mounted on vertical axes with possible rotation and creation by edges, directed outwardly, of surface having at least one arc-bent portion. Axes of each indicator element are held on lower driving base and upper non-driving base. Device is provided with a drive. On the axis of each indicator element a tailing toothed conical wheel is mounted. Drive contains a system of driving shafts number of which matches that of indicator elements. Shafts are interconnected by cardan joints, tails of which are mounted inside shafts. On each shaft a bushing is mounted having two radial shelves. First shelf is a sector of toothed conic wheel, second one has shape of sector of flat ring, shelves being positioned on different ends of bushing and oriented diametrically oppositely. First shelf is made with possible interaction with tailing wheel. Present on tailing wheel is an additional axial shelf, divided by radial slits on six sectors. Angle between adjacent slits is 60°. Second shelf of bushing, made with possible interaction with aforementioned recesses in tailing ring, acts as means for providing static position of prisms during demonstration of advertising image. Edges of indicator elements, directed outwardly, may form closed cylinder-like surface. Three-edged indicator elements may have flat, concave or convex edges.

EFFECT: possible generation of three successively changing information fields on advertisement carrier with curvilinear-convex and/or curvilinear-concave portions, remaining in static state for given time, required for viewer to inspect the resulting image.
