Abstract
A swinging and sliding door for rolling stock, especially a car that rides on a track, in mass transit. The panel of the door slides along a guide that pivots across the plane of the door on two cranks with vertical axes. The door has a system of articulations that will ensure a sufficient angle on the part of the door panel as the door begins to open even when the cranks are relatively short. The cranks, a rigid coupling that has the guide mounted on it and connects the cranks, and crank journals that are rigidly secured to the door frame form a four-member articulation, with the cranks rotating in opposite directions.
