    Abstract: An automotive vehicle body has a side opening that is opened and closed by a sliding door. The door is operated with a power drive mechanism that is pivotally mounted thereon and extends through the side opening. The power drive mechanism includes a reversible electric motor driven friction drive wheel and is spring biased to forcibly engage this wheel with a drive/guide track that is located beneath the vehicle floor and attached to the vehicle body. The friction drive wheel rides on the drive/guide track to open and close the door and also helps guide and stabilize its sliding movement. The spring load on the friction drive wheel is limited so as to provide sliding door operation with the motor under normal conditions and allow slippage at the friction drive wheel to cease door movement when the door encounters a physical object in the door opening.

    Abstract: An elevator car has a drive mechanism mounted in a compact housing on the upper surface of the car. The drive mechanism includes a rotatable drive shaft, around which is mounted a linear actuator block having a plurality of ball bearings, obliquely arranged relative to the shaft, and firmly touching the shaft. Rotation of the shaft by a motor makes the block move linearly along the shaft. A bracket attached to the block carries an elevator door. Rotation of the shaft therefore opens and closes the door. The direction of movement of the block, and hence the door, depends on the direction of rotation of the shaft. The drive mechanism is compact and simple, and can be applied to new elevators or can be used to retrofit existing elevator cars.

    Abstract: A folding door apparatus for a railway platform has a plurality of continuously provided folding doors each composed of two elements, a mid-portion between the two elements serving as an inflection point, the plurality of folding doors being movable between closed positions in which the folding doors are disposed in a line along a railway platform and inflected positions in which openings in the folding door apparatus are formed; a door opening and closing driving apparatus including a pair of opening and closing acting bodies for moving the folding doors in a direction and amount necessary to form the openings in the folding door apparatus; and a logic unit for analyzing information regarding the positions and widths of entrances of a railway vehicle stopped at the platform, and controlling the direction and amount of movement of the folding doors such that the openings in the folding door apparatus correspond to the entrances of the railway vehicle.

    Abstract: A horizontally sliding door section with a floor-engaging wheel driven from a motor. The wheel and its drive are located within the front-to-back extent of the door section in a housing hinged at one end on the bottom of the frame of the door section. A lead screw operated by a manual crank can be used to pivot the housing up about its hinge to raise the wheel from engagement with the floor of the building. The housing for the wheel has a removable front wall which carries the front bearing for the axle of the wheel, so that removal of this front wall disengages this bearing from the wheel axle.
