A rotary stand for TV screen or monitor, which require an adjustable angular position relative to its vertical axis, secured in a holder in a bearing column, mounted rotationally in a fixed mount, fitted with a controlled electric drive of the bearing column bi-directional rotation and a potentiometer for electric adjustment of the bearing column angular position is described together with a support stand that is mountable to a lateral wall. A potentiometer directly coupled with the bearing surface, and a friction clutch, as a component of a kinematic drive chain, transfers torque from the electrical drive to the bearing column. The stand has a programmable control system enabling the limit angular positions of the screen secured in the holder on the bearing column to be automatically set and programmed. |
