Abstract: An entrance device for placement in a facade of a building includes at least two revolving doors. Each of the revolving doors has an input section and an output section. A sliding door provides closure of the input and output sections of the two revolving doors. The sliding door is disposed between the two revolving doors.

Abstract: A revolving door lock is positioned on an inner space of the building and is sealed to the outside so that no heat energy is lost for nothing and hardly no draught appears. There is no need for three or four wings at the individual revolving doors so that with each revolving door more space is available for the passage with trolleys, wheel chairs, luggage and the like. Furthermore, the revolving door lock can be passed quickly, in that at each revolving door a free passage is possible since only one of the doors should effect a seal at a time, while the other one can be fully open. As a result, several persons may pass through the revolving door lock in their own speed without interfering with each other.
