Abstract

A sliding wing door, as used in railway and similar installations, is disclosed, of the kind in which the door, as it is opened, is first thrust out of its doorspace and slid alongside the vehicle body, the improvement consisting in that one of the component parts of the telescopable guide of the door panel is secured to the movable members of at least two linear ejectors intended to thrust the door panel out of the doorspace. Advantageously, the axes of the two (or more) linear ejectors are inclined through an angle of from 45.degree. to 90.degree. relative to the door space plane. A vertical shaft, mounted parallel and adjacent to the door post provides the initial movement of the door in a direction parallel to the ejector axes: the angle of rotation of the shaft is appropriately limited consistently with the necessity. Certain translation movements of component parts of the mechanism are aided by sets of rollers sliding on specially provided rolling paths.
