Abstract

A revolving door lock having outer walls defining in-between said walls a passageway, comprising at the extremities of the passageway a first revolving door and a second revolving door that embody an entrance and an exit of the door lock, wherein each of the first revolving door and the second revolving door is provided with shell-walls shaped as parts of a cylinder-wall and wherein the revolving doors each have door-wings that are rotatable between said shell-walls such that during rotation extremities of said door-wings are movable adjacent to said shell-walls.

Claims

1. Revolving door lock having outer walls defining in-between said walls a passageway, comprising at the extremities of the passageway a first revolving door and a second revolving door that embody an entrance and an exit of the door lock, wherein each of the first revolving door and the second revolving door is provided with shell-walls shaped as parts of a cylinder-wall and wherein the revolving doors each have door-wings that are rotatable between said shell-walls such that during rotation extremities of said door-wings are movable adjacent to said shell-walls, wherein each of the first revolving door and the second revolving door is provided with at least three wings.

2. Revolving door lock according to claim 1, wherein the shell-walls are arranged such that when a wing of a revolving door is positioned perpendicular to an imaginary line through the axes of rotation of the door-wings, another wing is having its extremity positioned immediately adjacent to a shell-wall so as to effect that said revolving door is closed against draught.

3. Revolving door lock according to claim 1, wherein it comprises control means that control the rotation or interruption and/or blocking of rotation of at least one of the revolving doors, which control means are receivingly connected with detection means for detecting unauthorized situations.

4. Revolving door lock according to claim 1, wherein the passageway is provided with means for recognition of a person'"'"'s movement-direction.

5. Revolving door lock according to claim 4, wherein the control means is arranged to interrupt and/or block rotation or to reverse rotation of the revolving door at the entrance when said means detects an unauthorized movement-direction.

6. Revolving door lock according to claim 4, wherein the said means are radar-transceivers positioned at the extremities of the passage-way.

7. Revolving door lock according to claim 1, wherein the passageway is placed off-centre with respect to an imaginary line through the axes of rotation of the door-wings so as to cause that passers-by can pass the door lock without noticeably moving sideways.

8. Revolving door lock according to claim 1, wherein the first revolving door and/or the second revolving door is equipped with means for object-detection selected from the group comprising object-sensors and a pressure-sensitive floor-part.

9. Revolving door lock according to claim 8, wherein the pressure-sensitive floor-part is provided in a predefined no-go area of the respective revolving doors, which no-go area is established in the path of passers-by going through the door-lock from the exit to the entrance.

10. Revolving door lock according to claim 8, wherein a control means is arranged to interrupt and/or block rotation or to reverse rotation of at least the revolving door of which the pressure-sensitive floor-part registers a load.

11. Revolving door lock according to claim 3, wherein the detection means for detecting unauthorized situations comprise one or more sensors for detecting objects in the revolving door at the entrance and/or the exit, and the control means is arranged to interrupt and/or to block rotation or reverse rotation of said revolving door upon activation of at least one of said sensors.

12. Revolving door lock according to claim 1, wherein it is provided with means on the shell-walls for scraping of objects sticking to extremities of the door-wings.
