The invention relates to a double-leaf vehicle door device comprising at least the following: two door leaves, each of which can be moved between an open position and a closed position in the form of a respective end position and into any intermediate position between the first open position and the first closed position, wherein a first movement of the first door leaf between the first open position and the first closed position is carried out without mechanically coupling the first door leaf to the second door leaf in contrast to a second movement of the second door leaf between the second open position and the second closed position, and a common locking device is provided which locks the first door leaf in the closed position when the first door leaf is located in the closed position and which locks the second door leaf in the closed position when the second door leaf is in the closed position. A pre-locking function is provided such that of the first door and the second door leaf, the door leaf which first reaches the closed position is held in the closed position at least until the other door leaf has also reached the closed position, and the locking device is additionally designed to only then lock or become capable of locking the first door leaf and the second door leaf.

A single-door control circuit for a train includes a first circuit for controlling a single door when the train is in a sleep state, and a second circuit for controlling a door of the train when the train is in a wake-up activated state. When the train is in the sleep state, the second circuit is not electrified, the first circuit works, a door control unit is electrified by a storage battery power supply, and the single-door control is triggered by an electric unlocking switch or a single-door button; and when the train is in the wake-up activated state, the first circuit is cut off, the second circuit is electrified, and under a condition that a cab on a local side is activated and the train is at a zero velocity, the single-door control is only triggered by activating the single-door button in the cab.

An arrangement for a vehicle, in particular a rail vehicle, or for a building, has a control system adapted to control a plurality of different devices, a cabinet having a lock that can be locked in order to prevent access to a valuable device within the cabinet, and a control unit of the control system adapted to remotely control unlocking the lock. The control system is adapted to unlock the lock automatically if a predetermined condition is fulfilled or to unlock the lock on demand.

Provided is a small plug door device having a slide base is installed slidably in a vehicle width direction relative to a fixed base. A door drive mechanism for moving one door in a vehicle front-rear direction via a connecting portion has a drive portion including an electric motor, a drive wheel member, a follower wheel member, and an endless member, and is installed on the slide base. A guide portion guides a shaft portion provided on the connecting portion so as to move the shaft portion in a vehicle width direction. In a double-speed rail in which a pinion is disposed between two racks, one rack is connected to the slide base, the other rack is connected to the door side, and the pinion is connected to the connecting portion.

It is aimed to provide a railway vehicle plug door device capable of easily ensuring airtightness between a side structure body and a door leaf even if the railway vehicle plug door device is installed in a side structure body having a structure assembled by joining structural members by welding and including a bent part. A frame body is mounted on a part constituting an entrance in a side structure body by a mechanical fastening structure. A seal member is mounted on at least one of a door leaf and the frame body and held in close contact with both the door leaf and the frame body when the door leaf closes the entrance.

A control apparatus includes a first controller which controls an operation of a door of a railway vehicle, a second controller capable of controlling the operation of the door, and a diagnosis tester. The diagnosis tester performs a diagnosis related to an abnormality in the second controller when performing a start process which accompanies turning on power of the control apparatus.

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.

The locking mechanism is adapted to a door system having a door unit slidably mounted to a door frame to open and close by sliding longitudinally along the door frame. The locking mechanism includes: a pivoting member pivotally mounted to one of the door frame and the door unit for pivoting about a pivot axis, and a hook member spaced apart from the pivot axis such that the hook member can pivot about the pivot axis via the pivoting member; and a guide member secured to the other one of the door frame and the door unit, the guide member having a channel formed therein to receive the hook member when the pivoting member is moved toward the guide by said sliding of the door, and subsequently maintain engagement with the hook member.

A lock mechanism includes a release cam assembly configured to be articulated around an axis of a spindle, an isolation lock unlock linkage, a primary lock unlock linkage, and a door panel suspension. Responsive to an emergency release being pulled, the isolation lock unlock linkage and the primary lock unlock linkage are configured to be sequentially actuated in a sequence that includes a) unlocking an isolation lock when the isolation lock previously was in a locked position, b) unlocking a primary door lock by rotational stroke motion of the spindle, and c) rotating the spindle in an open direction.

The manual release mechanism described herein enables a passenger to attempt to manually open the transit door, but delays opening until the vehicle is no longer moving. A motion transfer device (14) moves to an unlocking position of the door lock (10) only when the manual release mechanism is activated to store energy in a mechanical energy storage device (40), and an electromechanical device (26) is de-energized to release the motion transfer device (14).
