ABSTRACT:
A device for the synchronized actuation of sliding doors, provided for two sliding doors moving indistinctly in the same plane or in two planes forming any angle, consisting of two pairs of cogwheels (8-8′) and (9-9′) between which there is arranged, inside of each pair, an also cog belt (10-10′), a connection part (13-13′) fixed to the corresponding suspension grip (6-6′) of the respective sliding door being joined to each one of these belts. Joined to the two neighboring cogwheels (9-9′) there are respective cogwheels (18-18′) of a larger diameter, directly meshing with one another, to synchronously transmit motion from one cog belt (10-10′) to the other, cogwheels (18-18′) which are kept joined by means of parts (20) bridging their shafts (19-19′) and maintaining the drive transmission both when the doors are coplanar and when they form any angle.
