A door comprises a plurality of elements 1 which have vertically running longitudinal sides 4 and horizontally running narrow sides 2,3. The longitudinal sides 4 are connected to one another in an articulated manner via hinges 5. The narrow sides 2,3 are guided displaceably by means of running rollers 6,11 in horizontally running guides 7,13. Provided in the region of the lateral boundary of the building opening which can be closed off by the door is an arcuate guide 18 which interacts with guide rollers 17, which are fastened on the elements 1, such that, upon displacement of the elements, the latter fold together in the region of the lateral boundary of the building opening. <IMAGE> |
