Abstract: A device for moving a swinging and sliding door in a mass-transit car, especially a car that travels along a track. Each panel of the door slides lengthwise along a guide element. The guide element moves as part of a four-point articulation across the plane of the panel. The lengthwise motion of the leaf is coordinated with its transverse motion by a rail. The rail is fastened to the doorframe. Guide means are fastened to the panel and engage the rail. A drive mechanism on the panel directs force toward the guide element. As the drive mechanism (20-22, 30 & 31, or 40 & 4n1) reacts it exerts torque on an expansion element (25, 35, or 45) between the guide element (3) and a supporting component (25.2, 35.2, or 45.2) attached to the doorframe (16). The torque produces a force substantially normal to the guide element. The force generates the transverse motion.
