Swinging-and-sliding door for vehicles, especially mass-transit vehicles
First Claim
1. A door assembly for a vehicle having a doorframe in a body, comprising:
- a door having insulation therearound;
means mounting the door for movement between a closed position wherein the door is in the door frame and an open position in two mutually perpendicular steps including a first step in which the door is displaced from the closed position and into a sliding position and a second step in which the door is horizontally slidable into the open position, the means comprising a roller carriage and a track, means fastening the track is horizontally to an inside surface of the door intermediate of a top and bottom thereof, means mounting the roller carriage on the door adjacent to a vertical edge of the door frame opposite a leading edge of the door in the closed position and on the same level as the track for movement back and forth in the track and a carriage holder fastened to the body for mounting the roller carriage for movement in and out in the same direction as the door in the first step, and wherein the door is at least to some extent flexible in the direction it moves in during the first step and means for subjecting the door to tension such that when the door is positioned with its insulated edge tight against edges of the doorframe, the middle of the door will resiliently bend in a direction opposite that of the first step.

Abstract
A swinging-and-sliding door for vehicles which opens in two mutually perpendicular steps, a first step wherein it bends out of a doorway-closed position and into a ready-to-slide position and a second step wherein it slides aside horizontally into a doorway-open position. The door is mounted with a roller carriage and a horizontal track fastened to the inside of the door essentially halfway up. The roller carriage is mounted in a doorway immediately adjacent to a vertical edge of a doorframe opposite to the leading edge of the door in the closed position and on the same level as the track. The roller carriage travels back and forth in the track and in and out in the same direction as the first door-opening step on a carriage holder. The door is at least to some extent flexible in the direction it moves in during the first door-opening step and is subjected to tension such that the middle of the door will resiliently bend to a prescribed extent in a direction opposite that of the first door-opening step.
