Lengthwise and crosswise movement in door leaves (1,1A) is coordinated by a guide rail with a fixed link to a door portal (2). A guide device engages in the guide rail by causing a driven force from a driving device (6) to catch on the door leaves towards guide elements (3,3A). Device generate or support crosswise movement. A vertical rotary column (10) turns on bearings on the door portal. |
