The door actuator generally has a receiving structure having a door carriage path; a first coil assembly and a second coil assembly both being mounted to the receiving structure along a common coil assembly plane and being longitudinally spaced from one another along the door carriage path by a spacing distance; and a door carriage being slidingly received by the receiving structure, the door carriage having a plurality of alternate-pole magnets provided along a magnet plane being parallel and spaced apart from the coil assembly plane, the first and second coil assemblies being operable to move the door carriage back and forth between the two ends of the rail.

A vehicle door for a railway vehicle and a railway vehicle includes the vehicle door include a first door skin, a second door skin and a foaming material forming a laminated structure, the foaming material being filled between the first and second door skins, wherein the first door skin has at least one folded edge portion, and the second door skin has a first bent edge portion tightly clamped in the folded edge portion in a position corresponding to each of the folded edge portions. Since during the fixing of the first and second door skins, at least part thereof is realized by a folding and clamping technique, adhesion failure risk between the door skins and a frame body is effectively lowered during use, the reliability of the fixed connection between the two door skins is improved, and the vehicle door weight and the production cost are reduced during manufacture.

One object is to provide a door leaf frame capable of easy manufacturing, a door leaf, and a method of manufacturing the door leaf frame. A door leaf frame includes: two face plates disposed on opposite surface sides of a door leaf so as to be opposed to each other; two side plates each positioned on a lateral side of the door leaf and connected to the two face plates to form a U-shaped section; and two fastening members fastened to the two face plates. The face plates and the side plates are positioned relative to each other by projections provided on the side plates and holes provided in the face plates.

The door device is provided with an opening frame defining an opening and a door for operating between a first door position and a second door position, the door making contact with the opening frame when at the first door position, the door being separated from the opening frame when at the second door position. A movable receiving portion constituted by at least part of the opening frame operates so that the opening is larger when the door is at the second door position than when the door is at the first door position.

A safety system for an enclosure includes a door. The safety system includes a triggering circuit configured to generate a trigger signal based on an event associated with the enclosure. The safety system further includes a fastener operably coupled to the triggering circuit, wherein the fastener is adapted to maintain the door of the enclosure in a locked condition and disengage itself to unlock the door of the enclosure in response to the triggering signal.

A train information management device sends and receives information to and from both a train-controlling in-vehicle wireless station for controlling an operation of a train, and a door-controlling in-vehicle wireless station for controlling vehicle doors. The device includes a wireless train control unit, an automatic operation unit, and a door control unit. The wireless train control unit receives route information represented by a consecutive block sequence and information on a stop limit location that the train may reach without hindering a preceding train, and if this route information includes a station block number, consults an in-vehicle database to extract, before the train arrives at a platform, an arrival track where the train is to stop, a stop target location at a stop station dependent on a travel direction of the train, and which of the vehicle doors is to be opened, and stops the train in accordance with the route information.

A door for rail vehicle has a frame-type door main body and covering metal sheets. The door main body is formed of profiled elements, which are connected to each other by way of corner connectors. The covering metal sheets are arranged on two opposite sides of the door main body. The profiled elements are connected to each other exclusively by way of a fixed but releasable connection by the corner connectors. A fire protection material is arranged between at least one covering metal sheet and the frame-type door main body in such a way that the fire resistance and the thermal insulation of the rail vehicle door are increased.
