Abstract

Rotating billboard, with the property of successively offering different faces of prismatic modules, by rotary movement thereof, characterized by the fact that each of said prismatic modules, all of them of the same number of faces, and of regular section, is endowed of a rotation axis coinciding with its geometric axis, whose axis has a chain sprocket mounted to receive the turning movement of a gearmotor to the supply of which a regulating element is connected that determines the periods of operation and stoppage of said gearmotor, acting in cooperation with an interlocking system constituted by a general strut that is driven by an electromagnet so that its longitudinal displacement produces the turn around its centers of two levers, articulated to said strut and that at its other ends, end in two points of attack intended to be inserted into notches for this purpose provided in disc each of them is mounted on an axis of a prism, all this in such a way that the simultaneous action of the gearmotor and the electromagnet cause unlocking and rotation, while, when the electromagnet is energized and the gearmotor is powered, the interlocking takes place, in the correct arrangement so that the expensive views of all the prisms form a continuous surface, on which appears, permanently or simply by a poster attached, the advertising motive corresponding to said rotating billboard.
