A sliding door module or pivoting sliding door module for a rail vehicle includes a door leaf and a support, which is aligned longitudinally in the sliding direction of the door leaf and is mounted such that the support can be displaced in the horizontal direction in particular transversely to the longitudinal extent thereof. The sliding door module or pivoting sliding door module also has a linear guide for mounting the door leaf, which is fastened to or integrated in the support. The door leaves are moved with the aid of a rack-and-pinion drive. The rack-and-pinion drive has a rack which is coupled only in the first end region thereof to the door leaf, and the floating end of which is engaged with a gearwheel that is mounted rotatably in the support.

The invention relates to a railway vehicle (1) having at least one door opening (2) and a door (3) closing the door opening (2). The railway vehicle (1) comprises a sensor unit (4), a drive and a monitoring computer (8). The rail vehicle (1) can have a control unit (10). The sensor unit (4) can comprise an optical sensor and/or a LiDAR sensor. The sensor unit (4) can scan both the interior (6) of the railway vehicle (1) and the exterior (7) of the railway vehicle (1) in three dimensions. The door (3) can be opened and closed by the drive. The monitoring computer (8) is connected to the sensor unit (4) via a data link. The control unit (10) is connected to the monitoring computer (8) via a data link. The sensor unit (4) can detect at least the presence of passengers in the interior (6) and in the exterior (7), the closing status of the door and the presence of obstacles in the door opening (2).

The invention also relates to a computer-implemented method for monitoring a door (3) in a door opening (2) of a railway vehicle (1), a computer program product and a computer-readable medium.

A compartment door for a vehicle has a bearing rod slide block with a rod sliding block arranged on a bearing bar. The bearing rod is connected by a sliding pair, and the compartment door is connected with the bearing sliding block through a plugging and pulling movement of the main body. The plugging and pulling movement of the main body includes a swing rod, a connecting rod and a roller, wherein an upper end of the connecting rod and compartment door are connected to a point B by a rotation pair, and a lower end of the connecting rod and the bearing rod slide block are connected to point D by a sliding pair. The upper end of the swing rod and bearing rod slide block are connected to point A by the rotation pair, and B, C, D are located on a same straight line.

A door structure of an electric rail car is provided to block outside noise and vibration. The door structure of the electric rail car includes a door frame, a guide rail and a sealing device. The door frame has an opening thereinside. The guide rail guides an opening and a closing of the door frame. The sealing device is inserted into the opening, descends to make contact with the guide rail when the door frame is closed, and ascends to be spaced apart from the guide rail when the door frame is open.

A simple, convenient and light weight compartment door is provided.

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.

When a side sliding door is in a fully closed state, there is a space between a first elastic structure and a second elastic structure, and a first projecting wall portion and a second projecting wall portion are located so as to overlap each other when viewed in a thickness direction of the side sliding door. An elastic fin includes: an attaching portion detachably attached to one of the first elastic structure or the second elastic structure; and a fin portion projecting from the attaching portion. When the side sliding door is in the fully closed state, the fin portion contacts the other of the first elastic structure or the second elastic structure.

A pivot sliding door guiding device includes a longitudinal profile with a guiding track and slider, supported on support rollers in a linearly movable manner in the guiding track, and which is connected to a door leaf and transfers a bearing load onto the slider. In the guiding track, convex bearing members extending in the longitudinal direction are disposed, on which support rollers of the slider with, in each case, peripherally extending concave guiding grooves roll and are retained in the transverse direction. The door leaf is connected to the slider whereby a center of gravity acts off-center on the slider in running and transverse directions. The slider has support rollers which serve for the load transfer of the load acting from the door leaf on the slider. The rollers roll on upper and lower convex bearing members, and transfer load of the door leaf via the convex bearing members.

A monitoring device for monitoring a state of a locking device, the locking device includes a first member, a second member configured to achieve a locked state of a door of a railway vehicle by establishing a predetermined positional relation with the first member upon a movement toward the first member, and a solenoid configured to move the second member in a first direction away from the first member, wherein the monitoring device is configured to monitor the state of the locking device based on an electrical state observed when a first coil of the solenoid is energized.
