Revolving door for placement in a facade of a building
First Claim
Patent Images
1. A revolving door comprising:
- curved, segmented shell elements not connected to each other, the shell elements comprising at least one movable wall segment, the shell elements are positioned between an inner wall and an outer wall defining at least one containment area therebetween, and the inner wall partitions the at least one containment area from an inner area and the outer wall for partitioning the at least one containment area from an outer area;
door leaves mounted on a rotation axis, the door leaves placed between the shell elements so that the door leaves are separated from the at least one containment area by the shell elements and positioned so that the door leaves are freely rotatable and are not directly coacting with the shell elements as an edge of each door leaf moves past the shell elements during rotation of the door leaves; and
a sensor system in communication with the at least one wall segment to move the at least one watt segment for opening or closing off at least one of the shell elements to the at least one containment area.

Abstract
A revolving door for placement in a facade of a building to provide an entrance and exit to the building, comprising a rotation axis and door leaves mounted on the rotation axis, placed between cylinder segment-like shell elements, wherein the shell elements comprise at least one movable wall segment. The movable wall segment either blocks or gives way to an area between the entrance and the exit.

6. A method for operating a revolving door comprising:
-
providing curved, segmented shell elements not connected to each other, the shell elements comprising at least one movable wall segment; positioning the shell elements between an inner wall and an outer wall defining at least one containment area therebetween, and wherein the inner wall partitions the at least one containment area from an inner area and the outer wall partitions the at least one containment area from an outer area; mounting door leaves on a rotation axis and placing the door leaves between the shell elements, and separated from the at least one containment area by the shell elements, so that they are freely rotatable and are not directly coacting with the shell elements as an edge of each door leaf moves past the shell elements during rotation of the door leaves; providing a sensor system in communication with the at least one wall segment to move the at least one wall segment for opening or closing off at least one of the shell elements to the at least one containment area disposed between an entrance area and an exit area, said containment; and providing for the sensor system to interrupt rotation of the door leaves when at least one of the shell elements is opened so that passage between the inner and outer areas is blocked.
