A lock mechanism is provided for use with a door assembly. The lock mechanism includes a lock bracket configured to connect to a door or hatch; a lock pin can be selectively moved between an engaged position in which the lock pin engages the lock bracket and a disengaged position in which the lock pin does not engage the lock bracket; and a linkage assembly connected to the lock pin and configured to be actuated to reversibly move the lock pin between the engaged position and the disengaged position, and a door or hatch release device can switch the lock pin from the engaged position to the disengaged position if the door or hatch release device is actuated after the linkage assembly has moved the lock pin into the engaged position.

A door system for a public transit vehicle includes at least one door opening and a door that closes this door opening, wherein a sensor unit performs three-dimensional and touch-free scanning of a passenger compartment in the area of the door opening. A process of monitoring and controlling such a door system includes the steps of touch-free and three-dimensional scanning of a passenger compartment in the area of a door opening with a sensor unit, and measuring distances, shapes, and movements of objects by evaluating the readings from touch-free and three-dimensional scanning.

A door opening/closing device includes: an opening/closing bar attached to a door, which is actuated by a motor and is used for opening and closing the door; a door closing state detecting part configured to detect whether the door is in a closed state; a locking device configured to lock and unlock the door; a lock pin capable of being moved to a locked position or an unlocked position by the locking device; an engaging member attached to the opening/closing bar, which includes an engaging part configured to engage with the lock pin moved to the locked position; a first spring provided between the opening/closing bar and the engaging member; and a locking control unit configured to cause the locking device to lock the door when the closed state is detected by the door closing state detecting part.

A door control device includes: a speed control unit configured to perform speed control of an electric motor that drives a door; a speed detection unit configured to detect a speed of the door; and an obstruction detection unit configured to detect obstruction between the door and a door pocket, upon a value of the speed of the door detected by the speed detection unit decreasing by a first predetermined value or more with respect to a speed command value in the speed control during a door opening operation of the door.

The present disclosure discloses a rail vehicle. The rail vehicle includes: a bogie, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; and in the length direction of the rail, a surface of a compartment at at least one end of the vehicle body and facing away from an adjacent compartment is provided with an escape door that can be opened and closed. The rail vehicle according to these embodiments of the present disclosure facilitates optimization the structure of an escape passage, reduction in costs, reduction in occupied space and the weight borne by the rail, and improvement in stability.

A rail vehicle car for transporting passengers comprising a car body, a car body floor, a car body ceiling and a front end area. An A-pillar is disposed in the front portion. The car body has a longitudinal extent and a transverse extent, and the longitudinal extent is greater than the transverse extent. The car body includes a height extension transverse to the longitudinal and transverse extensions. The A-pillar is substantially centered in the transverse direction so that the front region is divided into a first side and a second side, and the first side comprises 30-70% of the transverse extent.
