DE 20 2012 102 617 U1 discloses a lock for receiving a person, their contactless identification and for recognizing textiles carried along. Another entrance to the room closed with the lock is possible via another entrance door, which is provided with a chip card reader for access control.

WO 2012/042043 A1 discloses a system and method for individualizing people upon passage through a door. A revolving door with two, three or four door leaves is described, which is designed for optical scanning in two planes when entering. In addition, an RFID tag can be read at the entrance to the revolving door.

WO 2009/087412 A1 discloses a generic revolving door with a cylindrical gateway formed from two rotating doors and two fixed wall sections. An RFID reading room is thus formed by the two cylindrical gateways and the wall sections.

Based on this, it is the object of the present invention to provide an improved revolving door which ensures reliable wireless reading of data with transponders by means of an electronic reading unit during passage.

The object is achieved with the revolving door with the features of claim 1. Advantageous embodiments are described in the subclaims.

It is proposed that the door leaf element has at least three door leaves attached to a vertical central axis and in the transition between the door leaves and sealing elements for electromagnetic shielding are arranged in the wall section which delimits the reading space. With the aid of these sealing elements, which are formed, for example, from electrically conductive wires, fibers or sponge structures, the space between the door leaves and the adjoining wall section is bridged in an electrically conductive manner. Carbon fibers or other electrically conductive yarns are suitable, for example, with which a sealing strip is formed in the transition between the door frame of a door leaf and the adjoining wall element for the electrically conductive connection of the door frame and wall surface. In this way, an improved shielding of the surroundings of the passage space from the wireless reading of data from transponders and electromagnetic waves emitted by the transponders is achieved by the electrical reading unit.

The revolving door has an electronic reading unit for the wireless reading of data from transponders, which is aligned with a reading space delimited by the wall section and a pair of door leaves. The wall section delimiting the reading space covers the pair of door leaves forming a passage space in a reading position of the revolving door. The wall section and the pair of door leaves forming the passage space are arranged and designed in such a way that the door leaf element and the wall section overlapping the door leaves contribute to the electromagnetic shielding of the reading room in the reading position.

The transponder can be read out quickly when the revolving door is rotating in the brief moment of a few seconds (approx. 2-5 seconds, preferably 3 seconds) in which the passage space is electromagnetically shielded from the surroundings of the housing. In the corresponding rotary position of the door leaves, the passage space is thus electromagnetically closed by the door leaf element and the wall section with the aid of an overlap, so that the passage space is essentially shielded for the passage of high-frequency electromagnetic waves.

For this purpose, the door leaves of the door leaves can be shielded electromagnetically, for example with a metallized film or a metal grille. The passage space delimited by the door leaf and the adjoining wall section is thus electromagnetically shielded.

However, it is also conceivable that a metal-shielded partition wall adjoins the door frame and adjoins the respective wall section. The interior of the revolving door formed by both wall sections and the partition walls is thus electromagnetically shielded from the outside as a whole. The opposite passage spaces in the door leaf element are then not electromagnetically shielded from one another. This is also not necessary if it is ensured that the two passage rooms are not used by different people at the same time.

The door leaves delimiting a passage space can thus optionally be connected on the side of the respective door leaf opposite the passage space by a partition to a door leaf which precedes or follows in the direction of rotation. In this way, a passage space of the revolving door following the passage space in the direction of rotation is closed off by means of the partition wall and cannot be entered. This ensures that the electronic reading unit only reads the transponders located in the passageway that can be entered and not any other transponders located in the vicinity of this passageway that can be entered. In addition, another person is prevented from entering the revolving door while a passage room that can be entered is still occupied by one person.

This means that the reading area does not have to be restricted to the pitch circle delimited by the door leaves. Rather, the entire housing can be used as a reading cell, since only a partial circle is used by one person for the passage anyway. An electromagnetically shielded partition also ensures that the electronic reading unit does not emit any electromagnetic waves into the area outside the housing delimited by the wall sections and the partition walls and that no transponders can be read outside this housing.

This ensures that transponders can be read reliably during the reading position with the aid of a reading unit aligned with the passage area.

The electronic reading unit can be controlled in such a way that it is only activated in the reading position and emits electromagnetic waves and otherwise does not emit any electromagnetic waves for interrogating transponders.

The door leaf element can have two opposing passage spaces which are each delimited by a pair of door leaves. It can thus be achieved that after the revolving door has been used by a person, the two passage rooms are each positioned in the open entrance area and opposite exit area, to which the partially circular wall sections adjoin. The part-circular wall sections together with the open entrance and exit area form a type of cylindrical body in which the door leaf elements are rotatably accommodated. The revolving door can thus be used without motorized assistance and, after a person has passed through, it can be used again by positioning the opposing passage spaces at the open entrance and exit area of the revolving door.

A direction of rotation limiting element designed to define the direction of rotation of the door leaf element can be coupled to the door leaf. In this way, the direction of rotation of the door leaf elements can be restricted to a preferred direction. This preferred direction can be either clockwise or counterclockwise in plan view.

It is advantageous if an access control unit is arranged at an entrance area and a person presence detector is arranged in an exit area of the revolving door opposite the entrance area. This means that access to the entrance area can be controlled and the presence of another person in the opposite exit area can also be checked.

In this context, it is conceivable that a locking element connected to a control unit is coupled to the door leaf element. This is then set up to prevent the door leaf element from rotating when access in the entrance area has been released by means of the access control unit and the presence of a person is detected in the exit area by means of the person presence detector. In this case, the person detected in the exit area could Enter the revolving door as well as the person in the entrance area who has been granted access. Then the person in the exit area could pass the revolving door in an uncontrolled manner. This is now prevented with the presence detector for the exit area, so that the revolving door can only be used after approval by the access control unit via the entrance area.

For a revolving door that can be accessed in both directions, there can be an access control unit at the entrance area and the opposite exit area. There can also be a presence detector for monitoring the entrance area and the opposite exit area. If access has now been released with an access control unit, then the person presence detector on the opposite side checks whether another person is there. In this way, the use of an access control unit defines the entrance and exit areas in the above sense. With a revolving door accessible from both sides, the entrance and exit areas can be swapped depending on the direction of access via the access control unit used.

It is advantageous if a display unit is arranged in the area of the entrance to the revolving door or on at least one door leaf. A data processing unit set up on the display unit to display the objects assigned to a user identified to enter the revolving door and provided with transponders for data reading can be connected to the display unit. When using the revolving door, it is thus possible for the user to be informed of the current status of the objects assigned to him with the aid of the display unit.

When accessing a laundry store, for example, this can be the number of items of laundry issued and provided with transponders, possibly broken down according to the type of laundry items. Thus, when entering the laundry store or also when leaving the laundry store with new laundry items carried along, the current status of the laundry items assigned to the user can be displayed.

However, the revolving door can also be used to identify the various types of objects carried by a user when passing through the revolving door.

This makes it possible, for example, to check the completeness of a person's equipment with objects and to issue a warning signal in the event that a given piece of equipment is missing. This is conceivable, for example, for rescue workers, such as fire fighters, who pass through such a security lock in the event of an alarm. The equipment carried by the rescue worker is then recorded via their transponder and assigned to the person. A completeness check can be carried out by comparing it with the type and number of items of equipment specified for the rescue worker.

The revolving door can have a predefined entrance side and a predefined exit side and can be designed to open the passage from the entrance side to the exit side and to block the passage from the exit side to the entrance side. For this purpose, additional barriers or automatic doors can be provided, for example, which are controlled on the entrance side via an access control unit.

A room access arrangement for an interior space accessible by means of two revolving doors can be designed in such a way that a first revolving door is arranged with its exit side in an interior space accessible through the revolving doors and the second revolving door with its entrance side in the interior space. This means that the interior can only be accessed via the first revolving door and the interior can only be exited via the second revolving door. On the other hand, leaving the interior via the first revolving door is prevented by the predefined access direction of the two revolving doors.

With this room access arrangement with the two revolving doors, it is conceivable that further secured entrances are available via further doors. This can, for example, be a material lock for loading or unloading the storage room, while the revolving doors are provided for individual access and the individual removal of objects from the storage room.

The invention is explained in more detail below using an exemplary embodiment with the accompanying drawings. Show it:

Figure 1 shows 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 arranged on a vertical central axis 4. The body 2 has two opposing partially circular wall sections 6a, 6b. In this context, part-circular is understood to mean that the wall sections 6a, 6b form a rounded or polygonal part-circle. The individual wall surfaces therefore do not necessarily have to be curved. Several flat wall surfaces can also be aligned in a polygon on a circular path.

The two opposing wall sections 6a, 6b each leave an entrance area E and an opposing exit area A open, through which the revolving door 1 can be entered and exited.

It can also be seen that a passage area delimited by a wall section 6a and door leaves 5 can be monitored with an electronic reading unit 7. This electronic reading unit 7 is aligned with the passage area in order to address transponders located therein and to wirelessly read out data stored in the transponders. An RFID transmission in the UHF wavelength range, for example, is suitable for this.

In the entrance area E there is also an access control unit 8. This access control unit 8 can be used, for example, by means of a chip card reader, fingerprint sensor, image capture by means of a camera, speech recognition by means of a microphone or the like and possibly a combination thereof and / or by entering an access code via a keyboard Person to be released into the revolving door 1. Only then is the door leaf element 3 unlocked and can rotate from an access position in a predetermined direction of rotation.

It is also clear that a partition 9 protrudes from the door leaves 5, extends to the following door leaf 5 and closes the space between these door leaves 5, which are closed off by the partition 9. Thus, the access to the space closed off by the partition 9 between two door leaves 5 cannot be entered.

At the exit area A, which is opposite the specified entrance area E, a person presence detector 14 is arranged, which ensures when entering a passage area (passage room) that at the same time as a permissible passage through the revolving door 1 via the entrance area E no additional person from the exit area A is opposite Entering the passage room. This ensures that only one person from the entrance area E uses a passage room. In addition, it can be ensured with the person presence detector 14 that a revolving door 1 which is only released in one direction is blocked in any case as soon as a person enters the revolving door 1 from the exit area A.

Figure 2 shows a sketch of a sectional view of the revolving door 1 in plan view. In this embodiment there are four door leaves 5, each arranged at an angle of 90 degrees to one another. The revolving door 1 is in the reading position. The accessible passage spaces, which are each delimited by two door leaves 5 arranged at right angles to one another, are completely covered by a partially circular wall section 6a, 6b overlapping the door leaves 5. The accessible passage space is thus each electromagnetically shielded by the door leaf 5 and the adjoining part-circular wall section 6a, 6b.

The door leaves 5 preferably have a suitable metal structure for electromagnetic shielding or are made entirely of metal. The door leaves 5 can, for example, also have glass surfaces that contain or carry a metal mesh. This metal mesh can, for example, be glued onto the door leaf surface as a film. The metal structure of the door leaf 5 is then preferably connected to a common ground potential via electrically conductive frame elements of the door leaf 5.

It becomes clear that at least one passage space is provided with an electronic reading unit 7 in the reading position. This is aligned with the passage space in the reading position in such a way that the objects 10 or their transponders 11 located in the passage space can be addressed. The electronic reading unit 7 is controlled in such a way that it only emits electromagnetic waves in the reading position for interrogating transponders.

It is conceivable that the two opposing passage spaces each have a reading unit 7. This option is indicated by the dashed second electronic reading unit 7 on the right-hand side.

It can also be seen that the revolving door 1 cannot be entered in the reading position in the entrance area E and exit area A. The space between the respective pairs of door leaves 5 is closed off by a partition 9 which is connected to the two door leaves 5 adjoining the entrance area E and exit area A, respectively. This partition 9 can, as shown, form a triangular surface together with the door leaves 5. However, it is also conceivable that the partition 9 is curved or angular in order to form a segment of a circle or a non-uniform polygon in section.

It is also clear that sealing elements 12 are arranged on the front edge of the door leaf 5 in the transition between the door leaves 5 and the adjoining wall section 6a, 6b. These consist of electrically conductive material, such as metal wires or a metal sponge. They can be designed as sealing strips that cause an electromagnetic seal. The use of carbon fibers or other metallic yarns is conceivable. Such electrically conductive elements can be brought together to form bristle or sponge structures, for example to form a bristle element. With the aid of these sealing elements 12, the door leaf 5 is electrically conductively contacted with the adjoining wall section 6a, 6b without the door leaf 5 being firmly connected to the wall section 6a, 6b. The sealing elements 12 are designed to slide along in contact with the respective wall section 6a, 6b, that is to say along the inner surface of the wall section 6a, 6b.

Figure 3 the revolving door 1 branches off Figure 1 and 2 in an intermediate position. There is a person P with the object 10, who has the transponder 11 to be read, in a passage area delimited by two door leaves 5. This is already partially open towards exit area A, so that the passage area is no longer electromagnetically shielded. The door leaf element 3 is manually rotated further by the person P, for example in the direction of rotation D, in order to finally reach an access position. The electronic reading unit 7 is deactivated in the intermediate position to such an extent that it does not emit any electromagnetic waves.

Figure 4 shows the revolving door 1 in this access position. There are two accessible passageways at the entrance area E and the exit area A. These passage spaces are only laterally bounded by two door leaves 5 arranged at an angle of, for example, 90 degrees to one another.

It goes without saying that the passageways and the revolving door 1 as a whole are completely closed at the bottom by a floor and also at the top by a ceiling.

It becomes clear that in the access position the areas that cannot be entered with the aid of the partition walls 9 are now laterally closed off by the part-circular wall sections 6a, 6b.

In the access position, too, the electronic reading unit 7 is deactivated to the extent that it does not emit any electromagnetic waves for interrogating transponders.

Figure 5 shows a plan view of a room access arrangement 13 for an interior space 14. This interior space 14 can, for example, be a storage room with a store 15 for objects 10, each provided with a transponder 11. Such objects 10 can, for example, be items of laundry or other items of equipment. The interior 14 can, for example, be a laundry store. It is also conceivable, however, that it is an equipment store that can be entered by people who are supposed to pick up different items of equipment.

A first revolving door 1a is now designed to enter the interior 14 from the outside. The first revolving door 1a is thus arranged with its exit side A in the interior space 14 that can be entered through the revolving door 1a.

A second revolving door 1b can now be entered the other way around and is arranged with its entrance area E in the interior space 14 accessible through the revolving doors 1a, 1b. It is therefore possible to enter the interior 14 exclusively via the first revolving door 1a and exit the interior 14 only via the second revolving door 1b. This can be controlled on the one hand by checking the direction of rotation and on the other hand by the access control units 8 arranged in the respective entrance area.

The person P can be informed about his current status in property management, e.g. about the items of laundry or other equipment assigned to him, on the entrance side E, for example via a display device of an access control unit 8 or a display unit arranged on a door leaf 5.
