ADVERTISEMENT-INFORMATION STAND Russian patent published in 2005 - IPC

FIELD: engineering of advertisement-information stands.

SUBSTANCE: dev has information elements, made in form of three-side prisms, on sides of which flat information carriers are held, and movement transfer assembly. The latter is made in form of multi-link crankshaft mechanism, consisting of aforementioned longitudinal tractions, mounted below one another, two groups of moving transfer links, joints and crankshaft. Electric engine is kinematically connected through crankshaft to lower longitudinal traction, connected through appropriate joints and first group of moving transfer links to upper longitudinal traction, which, in its turn, is kinematically connected through second group of moving transfer links to axes of three-side prisms, in angles of which vertical grooves are made. Information carrier plates are made of thin metallic sheets, edges of which along long sides are bent inwards with forming of resilient linear elements, which are used to provide connection of plates to three-side prisms.

EFFECT: synchronized operation of device without additional technological means, reliable and efficient connection of information carriers to prism sides.
