Abstract: A safety apparatus is associated with otherwise conventional revolving doors which are rotatable about a vertical axis. A pair of closure components are positioned adjacent to the respective sides of a revolving door and are displaceable in the horizontal direction. The closure components include profiled surfaces which delimit access space of the revolving door. In case of emergency situations, e.g. caused by a fire, the closure components are moved away from one another under the power of two respective jacks, leaving access space around the sides of the door wide enough for the passage of persons.
