Abstract
The device for guiding and actuating a vertical air-tight sliding door is suspended from two carriages each provided with a right-angled support bracket which is capable of horizontal displacement in a slideway. A bent plate which carries the door is rotatably mounted on an elbowed shaft fixed on each carriage. The bent plate carries a roller controlled by a fork and plate assembly which is pivotally mounted on the shaft and actuated by a jack. As the roller reaches the end of the track, the fork and plate assembly is permitted to rotate, with the result that the door carries out a compound movement of downward displacement and application against the wall.
