DEVICE FOR DISPLAYING INFORMATION FIELDS Russian patent published in 2009 - IPC G09F11/00 

FIELD: construction.

SUBSTANCE: present invention pertains to advertisement and can be used for presenting different, successively alternating information. The device has a frame with an actuator and blocks fitted on it. On side posts of the frame, there are parallel link mechanisms, consisting of piston rods, upper and lower cranks. One of the lower cranks is joined to a solenoid stem. On the piston rods there are Y-shaped pushers. Blocks at both ends are horizontally fixed to the frame by centre screws. On the centre screws there are two cups - support and driving. The cups form a circular inverted L-shaped recess. In the recess, there is an inner driving pin, in contact with the inner surface of the driving cup. Two outer driving pins are in contact wit the outer surface of the driving cup. The pins are fixed in holders, in which there are two pressure pins and threaded holding pads. Between the pads and the pressure pins there are cross bars with information elements fixed to them by one end. The other end of information elements is fixed to cross bars of adjacent holders. When folding, information elements settle between cross bars. Between holders there are elastic rings, fixed to the holders. In the spaces between outer driving pins of the lower vertical holders, there are ends of elastic members of countermove locks. Mounting pads of elastic members of locks are fitted in a frame.

EFFECT: simplification of the design of the device by reducing the number of blocks, simplification of changing information fields and more reliable operation.
