Revolving door lock
First Claim
1. A revolving door lock having outer walls laterally defining a passage space, comprising at least two revolving doors coupled for relatively synchronous movement and each having two wings rotatable about respective vertical rotating axes of the revolving doors, with an angle of said wings of the revolving doors with respect to a line of symmetry in a longitudinal direction being an angular off-set of 90°
- so that the passage space with respect to the line of symmetry also has an angular off-set of 90° and
the passage space is always closed at least on one side, wherein the rotating axes of the revolving doors are positioned at a distance which is at least about 2.25 times greater than the radius of one of the revolving doors to create an intermediate space between the revolving doors which is sufficiently large enough for a person to stand therein without interference from the 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.

8. A revolving door lock having outer walls laterally defining a passage space, comprising at least two revolving doors coupled for relatively synchronous movement and each having two wings rotatable about respective vertical rotating axes of the revolving doors, with an angle of said wings of the revolving doors with respect to a line of symmetry in a longitudinal direction being an angular off-set of 90°
- so that the passage space with respect to the line of symmetry also has an angular off-set of 90° and
the passage space is always closed at least on one side, wherein the rotating axes of the revolving doors are positioned at a distance which is greater than the sum of the radius of both revolving doors to create an intermediate space between the revolving doors which is sufficiently large enough for a person to stand therein without interference from the revolving doors, with a synchronizing device for each revolving door comprising an angular encoder delivering a certain number of pulses for each revolution of a respective revolving door so that a counter position indicates a rotational position of the respective revolving door, and at least one position detector for detecting at least one particular revolving position of the respective revolving door, wherein a processing unit is provided to which the angular encoder and the position detector is connected and which controls drive motors, said processing unit resets the counter position of the angular encoder to a starting position when the at least one position detector signalizes that a particular rotating position is reached, and said processing unit is adapted to allow the revolving doors to move with a synchronized adjustable speed by means of the angular encoder and the at least one position detector. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
