ABSTRACT OF THE DISCLOSURE A door assembly in a construction for preventing the transition of interference fields, in particular of high-frequency electromagnetic fields, into a space, wherein the contact zone between the door and a stationary structure is sealed by a labyrinth construction which attenuates the transition of interference fields. In prior art constructions, the provision of such labyrinth con- structions increases the difficulty of door operation as a result of the high compression force which is required for closing the door as well as the tendency of the pivoting movement of the door to damage the labyrinth construction. In order to overcome this problem, apparatus are provided such that the movement of the door comprises the usual pivoting movement thereof with respect to an axis and, additionally, a substantially linear controlled final path of movement during which a contact preventing the transition of interference fields is produced.
