The present invention relates to a device fitted onto a table. The distinctive feature of this device is to be either retracted inside the table, or at the level of the table. The top of this table, at its centre, has a cutout forming a shaft receiving the device. In its position raised up from the table, the device forms a turret composed of a double platform 5 and 3 connected to each other by four columns 4. The upper platform is provided with an inlaid draught board 2 and one identical with that of the table. The lower platform of the turret 5, which is smaller, is provided at its periphery with a trim forming a stop. The latter is mounted on a bearing 6 itself secured to another platform 7 closing the shaft made in the table. The above bearing allows the complete unlimited rotation of the turret. <IMAGE>
