MULTIWAY ROTATORY DEVICE FOR DEMONSTRATION OF INFORMATION MATERIALS Russian patent published in 2008 - IPC G09F11/02 

FIELD: physics.

SUBSTANCE: device includes frame, consisting of support elements with fixed plane. The central axis, arm with screwing protuberance and supporting rollers are installed on the fixed plane. One of the rollers is lead and joined with a drive component. C-shaped arms of units are fixed circle-wise on upper plane. A flywheel for contact with screwing protuberance and driving lever with springing element to turn horizontal ledges are mounted on the central axle of each unit. Vertical ledges with the informative elements are fixed to the horizontal ledges by tapped jaws. The horizontal ledges are placed between antifriction rings fixed to C-shaped arms on their horizontal plane. The vertical driven fingers of the horizontal ledges and springing elements of the driving levers come into and out of contact due to the shape of the planes and chamfers on the edges. The horizontal ledges are fixed by cylindrical locks with a slot for pass-through of the horizontal driven fingers of the horizontal ledges. The device is reliable in operation and ensures simple change of information fields.

EFFECT: development of reliable device ensuring simple change of information fields.
