One object is to provide a plug door device that can make a contribution to a size reduction thereof, while suppressing a decrease in airtightness of a door. A plug door device is provided with an electric motor, a plug operation portion that moves a door in a width direction of a vehicle, a front-back operation portion that moves the door in a front-back direction of the vehicle, a movement suppressing portion that can suppress movement of the door in the front-back direction, and a planetary gear mechanism that distributes a drive force of the electric motor to the plug operation portion when movement of the door in the front-back direction is suppressed by the movement suppressing portion, and distributes a drive force of the electric motor to the front-back operation portion when movement of the door in the front-back direction is not suppressed by the movement suppressing portion.

The present invention is to provide a vehicle door switch that is capable of adjusting the amount of movement made by a rod with ease and a method for attaching a vehicle door switch. A vehicle door switch includes a rod configured to move as a door is closed, a detecting unit configured to output a detection signal when one of ends of the rod has moved by a predetermined distance or more, and a limiting unit configured to limit the amount of movement made by the rod within a range where the detecting unit outputs the detection signal.

A motorman's cab in a train is provided with a plurality of door operating switches that open and close the train doors on the station-platform side in a fully-automatic manner, in a semi-automatic manner, or in a manner that open and close doors in sections. A central device includes an information control unit that specifies a stopping station where a train stops next on the basis of train information; selects a recommended door operating switch at the stopping station from among the door operating switches on the basis of an estimated passenger-number value, which is the number of passengers at the stopping station, as a recommended door operating switch for the stopping station; and then it displays display information that prompts the train crew to operate the selected door operating switch on a display device in the control platform.

A rotary valve and a quick exhaust valve for a railway vehicle in which high sealability and operability at the time of valve opening and closing are ensured. Outflow/inflow ports (10, 11) and a discharge port (12) are formed in a valve body accommodating part having a spherical surface part or a tapered surface part formed on part of an inner periphery in a body (2), and a valve body (3) is rotatably inserted from an opening which is open from the valve body accommodating part. A spherically-shaped surface part or a tapered-shaped surface part is formed at a position opposing the spherical surface part or the tapered surface part, a plurality of through ports communicating the outflow/inflow ports or the discharge port and an attachment groove opposing the outflow/inflow ports in a direction crossing the through ports are formed, and a seal member is attached to the attachment groove.

A door control system for a farm implement with a storage bin having a discharge opening and a door movable by a drive mechanism between open and closed positions relative to the discharge opening includes a dual position door control system. The system includes at least two controllers at spaced positions relative to the door and coupled to a drive mechanism for opening and closing the door.

An opening and closing apparatus with a lock that is provided is capable of safely and promptly closing a sliding door, and also easily performing unlocking with a simple configuration. In an opening and closing apparatus with a lock for opening and closing sliding doors that are provided with elastic members at their door leading ends, output of an electric motor is transmitted to a rack-and-pinion mechanism or a lock mechanism. A control unit controls the electric motor such that a closing operation is performed, the closing operation operates the rack-and-pinion mechanism so as to move the sliding doors to a fully closed position and then displacing a link mechanism in a lock mechanism from an unlocking position to a locking position. Furthermore, the control unit controls the electric motor so as to reduce the output of the electric motor at a predetermined intermediate time point during the closing operation.

An operating mechanism for plug-type rail car doors includes first and second links connected to respective rotatable first support bars of the door. The links include respective elongated slots at least partially overlapping with one another, wherein each slot receives a respective cam. The cams are rotatable together about a rotational axis which is eccentrically arranged relative to both cams. An actuating lever is connected to the cams to enable an operator to rotate the cams about the rotational axis. The actuating lever is movable such that the first and second links are retracted relative to one another to simultaneously rotate the first and second support bars, and such that the first and second links are extended relative to one another to simultaneously counter-rotate the first and second support bars. A gear train may be provided between the actuating lever and the cams to reduce the necessary manual operating torque.

The invention relates to a method for distinguishing, detecting and counting persons and/or objects in vehicles for conveying persons and/or goods, with the method steps: emitting radiation from a radiation source, deflecting the radiation with an element for deflecting the radiation, generating a light pattern in a detection region with a beam density ρ.sub.s of 5*10.sup.2/4*πsr.sup.−1≤ρ.sub.s≤10.sup.6/4*πsr.sup.−1, and detecting the radiation backscattered by persons and/or objects situated in the detection region in a radiation detector, as well as a corresponding person and/or object counting device.

A pivoting and sliding door device for arrangement in a door opening of a door frame of a vehicle, in particular a rail vehicle, includes at least one pivoting and sliding door, which has a door leaf which is movable relative to the door frame and is mounted on the door frame between a door leaf closed position and a door leaf open position such that the movement direction of the door leaf runs substantially horizontally during an opening process and during a closing process.
