ADVERTISING EMPLACEMENT Russian patent published in 2006 - IPC G09F11/04 

FIELD: aids for visual data transmission.

SUBSTANCE: emplacement can be used at movable advertising emplacements. It has prisms rotating around their own axes. Prisms have components applied onto their faces which components compose changing advertising image. Emplacement also has drive shaft and prism rotating mechanism. Rotating mechanism has leading discs mounted onto drive shafts. Discs have protrusions interacting onto lockers of driven discs. Driven shafts are mounted for simultaneous rest contact of four from lockers with two internal diametrical planes of doubled driven shafts and for simultaneous contact of rest two lockers with two external diametrical planes of doubled drive shafts. One of leading discs is made with three open slots and with two protrusions between them. The other leading disc has to be segment of circle. Prism rotating mechanism is made for reversal rotation due to mutual perpendicular crossing of axes of rotation of drive and driven shafts. The latter has slots and protrusions disposed symmetrically relatively axis of rotation of prisms.

EFFECT: stable and accurate operation; improved reliability.
