The invention is concerned with a door in a construction forming an electromagnetically protected space, wherein the contact zone between the door (1) and the stationary construction (2) has been sealed by means of a labyrinth structure (3 to 6) attenuating the transition of interference fields. A problem related to the prior-art door constructions f this type is the loss of the ease of operation of the door and loss of the customary operating properties of a normally hinged door when an efficiently attenuating labyrinth structure is used, as a result of the high compression force required for closing the door as well as of the tendency of the pivoting movement of the door to damage the labyrinth structure. In the invention, this problem has been overcome in practice so that the movement of closing of the door (1) consists of a normal pivoting movement around an axis (8) defined by the hinge devices (7) as well as of a substantially linear controlled final movement producing a contact preventing the transition of interference fields. |
