A device to open and connect an opening comprising a tow-way pivoting movable door (2) around a shaft (5) using an expandable power device (3) and a control device (4) and a direction selector device (11) to control the movement of the door in the desired direction, to which the power device (3) is connected (at 21 and 22) between a fixed point and the control device (4) is connected to the door. The control device is stored around the shaft (5) so that the linkages (21, 22, 5) are aligned with each other when the door (2) is in the closed position and at which point the direction selector device (11) affects the desired direction of travel for the door (2) by acting upon the linkage (22) in one direction from the aforementioned line.<IMAGE> |
