FIELD: transportation. ^ SUBSTANCE: door contains a leaf, driving, transverse and longitudinal guiding mechanisms allowing, at least, one door leaf to cross and along the transport vehicle wall. The longitudinal guiding mechanisms can operate crosswise by means of transverse guiding mechanisms. The door, as-closed, is locked against spontaneous opening by rotary part (10) interacting with guide (12). Rotary part (10) incorporates guiding part (11) to interact with guide (12). The guide has section (12b) in the form of an arc of circumference about an instant position of axis (9) of the rotation of rotary pat (10), part 12b being arranged in the zone wherein rotary part (10) interacts with closed door. ^ EFFECT: safe opening of the door in emergency without increasing the mechanism sizes. ^ 5 cl, 9 dwg |
