Door intended to be used with a new type of thick partition walls, which are built up by prefabricated elements, where the inner parts of the wall are used as filing cabinets. The door has good sound reduction characteristics, is easy to manoeuvre and is space saving. The door comprises two door panels (14, 15) each placed at one wall surface. Each door panel has two door halves (14a, 14b, 15a, 15b) which are connected to each other by hinges (17). The door panels are connected to each other via a link mechanism (20, 21, 22, 23, 24) so that the door halves in each door panel are moved towards each other during the opening movement of the door and after having been opened are placed nearby each other on either position of the door after it is open. |
