Abstract:
A circular translation opening system for plates of counters and display units, whereby the plates slide longitudinally and at the same time they rotate, characterised by the fact thateach plate is fixed to a first bar having a length which is shorter than that of each plate; whereby each plate is fixed to said respective first bar directly or by clamps; two supporting arms are hinged to each of said first bars by pivots; the two supporting arms of each first bar are hinged by other pivots to a lower bearing bar fixed to the counter or the display unit; said supporting arms are parallel and their pivots are positioned near ends of the supporting arms; an elastic device is connected to at least one supporting arm; a first end of said elastic device is hinged by a first pivot to a point close to the lower bearing bar of the at least one supporting arm; a second end of said elastic device is hinged by a second pivot to the lower supporting bar; the two supporting arms of each plate in co-operation with each first bar and the lower bearing bar form a parallelogram moving system; and each plate may translate to the right or to the left according to the orientation of the supporting arms.
