Abstract:
Drive system for moving a load along a curved path. The drive system includes a base for mounting the drive system, the base having a curved track for guiding the load along the curved path. There is a load engaging mechanism mounted on the base for movement relative to the base, the load engaging mechanism being for moving the load. The load engaging mechanism has a curved track engaging roller for engaging the curved track. A linear drive mechanism including a linearly driven member is mounted on the base. The linearly driven member includes a driving pivot. A drive link is attached to the driving pivot at a drive force receiving end of the drive link, the drive link including a driven pivot at a drive force communicating end of the drive link. The driven pivot is attached to the load engaging mechanism, whereby linear motion of the driving pivot causes motion of the load along the curved path.

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.
Abstract:
The door comprises at least one sliding leaf which is capable of engagement and disengagement transversely within the door-frame, two separate toothed racks being mounted on each leaf and each associated with a pinion supported by a guided carriage, the two pinions being coupled by means of a coordinating shaft. Operating means comprising a motor and a mechanism for driving the pinions are rigidly fixed to at least one of two crank-arms, each crank-arm being pivotally connected to a carriage and to the door-frame.
Abstract:
Die Erfindung betrifft ein Schwenkschiebetürmodul (1a..1d) mit zumindest einem Türflügel (2, 2a, 2b) und einem quer verschiebbar gelagerten Längsträger (3), entlang dem der zumindest eine Türflügel (2, 2a, 2b) längs verschiebbar geführt ist. Zudem umfasst das Schwenkschiebetürmodul (1a..1d) einen mit dem Längsträger (3) und mit dem zumindest einen Türflügel (2, 2a, 2b) gekoppelten Antrieb (16, 17). Ein vom Antrieb (16, 17) ausgehender und auf den Längsträger (3) beziehungsweise den zumindest einen Türflügel (2, 2a, 2b) wirkender Kraft- und/oder Drehmomentfluss (27a..27d) teilt sich dabei fächerförmig auf. Zudem weist das Schwenkschiebetürmodul (1a..1d) mehrere zusätzlich zum Antrieb (16, 17) wirkende Betätigungselemente (31..33, 52a, 52b, 60, 61, 65) beziehungsweise Funktionen (F1..F7) auf, welche eine Bewegung des zumindest einen Türflügels (2, 2a, 2b) verursachen oder eine solche Bewegung verhindern. Die Mehrzahl der genannten Betätigungselemente (31..33, 52a, 52b, 60, 61, 65) / Funktionen (F1..F7) ist dabei an einem einzigen Zweig (Z1..Z11) des genannten Kraft- und/oder Drehmomentflusses (27a..27d) angekoppelt.
