The invention relates to an advertising device, which can be implemented in the field of advertising through exposing on public places of big format full colour images (as posters, billboards etc) of goods and/or services being advertised. The device is formed as a vertical regular n-angular prism, n being freely optional number, rotating around its longitudinal axis of symmetry and a possibility is also provided for mounting the whole device on a lorry platform. The vertical rectangular walls of the prism are performed as observing windows (1.1, 1.2, . . . 1.n) whereon can be watched the consecutive appearance of independent images, printed on a flexible tape. The advertising device is carried out as a set of several kinematically independent contours (modules) mounted on a common internal frame (6) where the observing windows of the particular modules form the outside visible walls of the device. The device enables a consecutive appearance of the images on the observing window without a necessity of a reversal of the direction of the movement of the tape with the images printed thereon in order to accomplish a full cycle. Thus a complete equality is achieved in term of frequency of appearance within the cycle of the images on the observing windows.
An advertising device, characterised in that it is performed as a regular n-angular prismatic body, comprising observing windows (1.1, 1.2, . . . 1.n), to each observing window, on common supporting frame (6), is formed a separate, kinematically independent contour, comprising a tape (21), rolls (7, 9, 14), arranged parallel to the vertical axis of symmetry of the prismatic body, the axes of rolls (7) being rigidly fixed to the supporting frame (6) by means of nuts (8), whilst the axis of a roll (9) is mounted in a flat slot cut out in the frame (6), said roll (9) having the possibility to be moved upon the frame (6) in a horizontal direction, a roll (14) being mounted by means of bearing assemblies (15) on the frame (6), whilst double-ended to the axes of rolls (7, 9) are fixed bearing assemblies (13) with chain gears (12) attached thereto, whilst to the axis of a roll (14) coaxially are rigidly fixed chain gears (16), to said chain gears (12, 16) being coupled chains (11), to which by means of springs (23) and plates (24) is attached a tape (21), the chains (11) on their part by means of plates (25) and bearings (27) being attached to hollow steel profiles (28), rigidly fixed to the frame (6), the tape (21) itself being formed as a closed contour is put upon hollow shafts (31), which are mounted double-sided by means of bearings on the axes of rolls (7, 9, 14), whilst to the lower end of the axis of a roll (14) coaxially is rigidly fixed a belted wheel (17), coupled by means of a belt (20) and a reducer (19) to an electric motor (18), connected by means of a relay (33) to a control-supply block (32), whilst the common supporting frame (6), on its part, by means of a rigidly fixed hollow shaft thereto is mounted coaxially to the vertical axis of symmetry by means of bearings on a steel axis, rigidly fixed to the foundation (4), to said hollow shaft being coaxially fixed belted wheel (38), connected through a belt (37) to a wheel (36), coupled to the output shaft of an electric motor-reducer (35), performing the rotation of the whole device.
