Description

[0032] The invention is explained in greater detail below with reference to an embodiment with the appended drawings, in which:

[0033] FIG. 1 is a perspective drawing of a revolving door;

[0034] FIG. 2 is a plan view of the revolving door from FIG. 1 in the reading position;

[0035] FIG. 3 is a plan view of the revolving door from FIG. 1 in an intermediate position;

[0036] FIG. 4 is a plan view of the revolving door from FIG. 1 in the access position;

[0037] FIG. 5 is a drawing of a room access arrangement having two revolving doors, wherein the first revolving door is constructed to access the inner space and the second revolving door is constructed to leave the inner space.

[0038] FIG. 1 is a perspective view of a revolving door 1. The revolving door 1 has a type of cylindrical body 2 in which a rotatable door leaf element 3 is arranged. The door leaf element 3 has at least three door leaves 5 which are arranged on a vertical centre axle 4. The body 2 has two mutually opposing part-circular wall portions 6a, 6b. The term part-circular is intended in this context to be understood to mean that the wall portions 6a, 6b form a round or polygonal part-circle. Consequently, the individual wall faces do not necessarily have to be curved. A plurality of planar wall faces may also be orientated as a polygon on a circular path.

[0039] The two mutually opposing wall portions 6a, 6b each leave an entry region E and an opposing exit region A open through which the revolving door 1 can be entered and left.

[0040] It can further be seen that a passage region which is delimited by a wall portion 6a and door leaves 5 can be monitored with an electronic reading unit 7. This electronic reading unit 7 is thus directed towards the passage region in order to respond to transponders located therein and to wirelessly read data stored in the transponders. For example, an RFID transmission in the UHF wavelength range is suitable for this purpose.

[0041] In the entry region E there is in addition an access control unit 8. Via this access control unit 8, for example, by means of chip card readers, fingerprint sensors, image detection using a camera, speech recognition using a microphone or the like and where applicable a combination thereof and/or by means of access code input via a keyboard, the access for a person into the revolving door 1 can be released. Only then is the door leaf element 3 unlocked and can rotate from an access position in a predetermined rotation direction.

[0042] It is further clear that there protrudes from the door leaves 5 a partition wall 9 which extends towards the following door leaf 5 and which closes the space between them by means of the door leaf 5 which is closed by the partition wall 9. Consequently, the access to the intermediate space between two door leaves 5 closed by the partition wall 9 is not accessible.

[0043] At the exit region A, which is opposite the predetermined entry region E, there is arranged a person presence detector 14 which, when a passage region (passage space) is entered, ensures that at the same time with a permitted entry into the revolving door 1 via the entry region E no additional person enters the opposing passage space from the exit region A. It is consequently ensured that only ever one person from the entry region E uses a passage space. In addition, the person presence detector 14 can ensure that a revolving door 1 which is released in only one direction is in any case blocked as soon as a person enters the revolving door 1 from the exit region A.

[0044] FIG. 2 is an illustration of a sectioned view of the revolving door 1 as a plan view. In this embodiment, four door leaves 5 which are arranged at an angle of 90 degrees with respect to each other are provided. The revolving door 1 is located in the reading position. In this instance, the accessible passage spaces which are each delimited by two door leaves 5 which are arranged at a right angle with respect to each other are completely covered by a part-circular wall portion 6a, 6b which overlaps the door leaves 5. The accessible passage space is consequently in each case electromagnetically shielded by the door leaves 5 and the adjacent part-circular wall portion 6a, 6b.

[0045] The door leaves 5 preferably have for electromagnetic shielding a suitable metal structure or are completely formed from metal. The door leaves 5 may, for example, also have glass faces which contain or carry a metal fabric. This metal fabric may, for example, be bonded as a film to the door leaf face. The metal structure of the door leaf 5 is then preferably connected to common earth potential via electrically conductive frame elements of the door leaves 5.

[0046] It is clear that at least one passage space in the reading position is provided with an electronic reading unit 7. This is directed towards the passage space in the reading position in such a manner that the objects 10 located in the passage space or the transponders 11 thereof can be responded to. The electronic reading unit 7 is controlled in such a manner that it transmits electromagnetic waves for interrogating transponders only in the reading position.

[0047] It is conceivable for both mutually opposing passage spaces to have a reading unit 7 in each case. This option is indicated by the dashed second electronic reading unit 7 at the right-hand side.

[0048] It can further be seen that the revolving door 1 in the reading position cannot be accessed in the entry region E and exit region A. The space located between the respective pairs of door leaves 5 is in each case closed with a partition wall 9 which is connected to the two door leaves 5 which adjoin the entry region E or exit region A in each case. This partition wall 9 may as illustrated together with the door leaves 5 form a triangular face. However, it is also conceivable for the partition wall 9 to be curved or angular in order to form a circular segment or a non-regular polygon in cross-section.

[0049] It is further clear that sealing elements 12 are arranged in each case at the end edge of the door leaf 5 in the transition between the door leaves 5 and the adjacent wall portion 6a, 6b. These comprise electrically conductive material, such as, for example, metal wires or a metal sponge. They may be constructed as sealing strips, which bring about an electromagnetic shielding. It is conceivable to use carbon fibres or other metal yarns. Such electrically conductive elements can be combined to form bristle or sponge structures, for example, to form a bristle element. By means of these sealing elements 12, the door leaf 5 is contacted in an electrically conductive manner by the adjacent wall portion 6a, 6b without the door leaf 5 being connected securely to the wall portion 6a, 6b. The sealing elements 12 are constructed to slide in a touching manner along the respective wall portion 6a, 6b, that is to say, on the inner face of the wall portion 6a, 6b.

[0050] FIG. 3 shows the revolving door 1 from FIGS. 1 and 2 in an intermediate position. In this instance, a person P is located with the object 10 which has the transponder 11 which is intended to be read in a passage region which is delimited by two door leaves 5. This is already partially open in the direction towards the exit region A so that the passage region is no longer electromagnetically shielded. The door leaf element 3 is turned further by the person P manually, for example, in the rotation direction D in order to ultimately reach an access position. The electronic reading unit 7 is deactivated in the intermediate position to such an extent that it transmits no electromagnetic waves.

[0051] FIG. 4 shows the revolving door 1 in this access position. In this instance, two accessible passage regions at the entry region E and at the exit region A are accessible. These passage spaces are laterally delimited only by two door leaves 5 which are arranged at an angle of, for example, 90 degrees with respect to each other.

[0052] It is self-evident that the passage spaces and the revolving door 1 are on the whole terminated downwards completely by a floor and also upwards by a ceiling.

[0053] It is clear that, in the access position, the regions which cannot be accessed using the partition walls 9 are now laterally terminated by the part-circular wall portions 6a, 6b.

[0054] In the access position, the electronic reading unit 7 is also deactivated to the extent that it emits no electronic waves to interrogate transponders.

[0055] FIG. 5 is a plan view of a room access arrangement 13 for an inner space 14. This inner space 14 may, for example, be a storage space having a store 15 for objects 10 which are each provided with a transponder 11. Such objects 10 may, for example, be items of washing or other items of equipment. The inner space 14 may, for example, be a washing store. However, it is also conceivable for it to be an equipment store which can be accessed by persons who are intended to take different items of equipment per se.

[0056] A first revolving door 1a is constructed to access the inner space 14 from the outer side. The first revolving door 1a is arranged with the exit side A thereof consequently in the inner space 14 which can be accessed through the revolving door 1a.

[0057] A second revolving door 1b is arranged so as to be accessible in the reverse manner and with the entry region E thereof in the inner space 14 which can be accessed through the revolving doors 1a, 1b. Consequently, access to the inner space 14 is possible exclusively via the first revolving door 1a and leaving the inner space 14 only via the second revolving door 1b. This may, on the one hand, be controlled by means of rotation direction control and, on the other hand, by means of access control units 8 which are arranged in the respective entry region.

[0058] The person P may in this instance be informed at the entry side E, for example, via a display device of an access control unit 8 or a display unit which is arranged on a door leaf 5 regarding his current status in the object management, for example, with regard to the items of washing which are associated with him/her or other items of equipment.
