DYNAMIC ELECTRIC SPECTACULAR Russian patent published in 2013 - IPC G09F11/02 

FIELD: mechanics.

SUBSTANCE: dynamic electric spectacular includes a frame, the base and the top of which are connected by means of vertical posts, a rotating device with demonstration units, which is arranged in the frame relative to the spectacular central axis and connected to its rotation drive, and a rotating mechanism of demonstration units. The rotating device is made of two demonstration units, each of which includes a supporting and turning table with a vertical rotation axis passing through its centre, on which there fixed are two demonstration surfaces bent along the arc of circle of the above table and arranged so that a cylindrical volume and vertical diametrically opposite lying openings are formed between them. Units are installed so that the supporting and turning table of one unit is located at the base of the frame, and that of the supporting and turning table of the other units is located at the top of the frame. Three vertical rotation axes of supporting and turning tables are offset to diametrically opposite sides relative to the spectacular central axis, and one of the demonstration surfaces of each unit is arranged inside cylindrical volume of the other unit. The rotating mechanism of demonstration units performs alternating rotation of supporting and turning tables through 180°, which provides the change of demonstration surfaces located inside cylindrical volume and outside it so that demonstration surfaces of the turned unit pass through vertical openings of the second unit.

EFFECT: simpler device design, increase in surface area of demonstration surfaces at maintaining high compactness of the device, enlargement of the number of dynamic electric advertising stands allowing simultaneous demonstration of several large-size advertising images.
