Roller door with one or two door parts (11, 12) which can be moved horizontally in relation to one another and which can be rolled up on winding-up rollers at the side of the door opening (15) and are guided in guide rails (16, 17) above the door opening (15), in which, to make possible rapid closing and opening of the door while avoiding tilting of the two roller door parts, the door halves (11, 12) are in each case driven by a drive unit (20, 21) which acts on a guide element (26, 27), one end of which is mounted in an articulated manner on the guide rail (13, 14) on the front edge of the door part (11, 12) and the second end of which is mounted in an articulated manner above or at the side of the door opening (15). <IMAGE> |
