DEVICE FOR DOUBLE-SIDED DISPLAY OF INFORMATION FIELDS AND METHOD OF DOUBLE-SIDED DISPLAY OF INFORMATION FIELDS Russian patent published in 2009 - IPC G09F19/02 G09F11/15 

FIELD: physics, training aids.

SUBSTANCE: invention relates to the field of advertising and can be used in double-sided advertising devices for presenting information which is sequentially interchanging. The device has a frame, a gear and a block. On the frame at the bottom and top are installed cut-off planes of blocks. To the cut-off planes are attached quadrilateral monorails with rectangular cross-section, two sides of which are straight, and two of which are semi-circular. On the monorails are placed carriages, moved by double-sided carriers and fixed with stoppers. Lower and upper carriages are connected with the upright poles, forming carrying frames. To the carrying frames is attached part of the information elements, the width which is equal to the width of the carrying frames. Part of the information elements is attached to two adjacent carrying double-sided frames. The width of information element is equal to the width of the block. Each block is formed from a pair of packets with the carrying frames. According to the proposed method the information field is divided to information elements, attached to carrying frames and formed in a pair of packets. In the starting position in one packet of each pair is placed a carrying frame with information elements for displaying on one side of the device, and in the other packet - carrying frame with information elements for displaying on the other side of the device. To change information fields from one packet to another simultaneously from both sides, the planes of the carrying frame are turned by 180° and folded during their convergence. Carrying frames are moved till all the carrying frames except one go to the other, after which the moving cycle is repeated in the opposite direction.

EFFECT: simplification of the gear construction and information elements and provides for easier replacement.
