The door device ( 10 ) is further provided with at least one air curtain device ( 30 ), essentially running along the complete height of the passageway ( 27 ) and which generates an exiting air curtain ( 33 ), such that, with the door ( 11 ) open, the passageway ( 27 ) is screened by the air curtain ( 33 ). The generated air curtain ( 33 ) serves to reduce the energy losses which occur when air from the outside ( 28 ) of the door device ( 10 ) reaches the inside ( 29 ) of the door device ( 10 ), or vice versa. According to the invention, a door device ( 10 ) may be achieved which not only permits the access of people and objects, but also identification of the people, objects, or similar and the management thereof is as uncomplicated as possible, whereby the door device ( 10 ) is provided with at least one additional identification system ( 40 ). Said identification system ( 40 ) comprises at least one sensor unit ( 41 ), a control unit ( 42 ) and an output unit ( 43 ) which are connected to each other. Furthermore, at least one sensor unit ( 41 ) in the identification system ( 40 ) is integrated in the air curtain device ( 30 ).

Description

Door with integrated identification system in the air curtain

The invention relates to a door device with at least one door, for opening and closing a passage according to the type specified in the preamble of claim 1. Such door devices are widely known in various embodiments. They are used to close the door opening of a passage e.g. Warehouses, specialty shops, airports, public buildings and the like. The door device mentioned also contains a vertical air curtain device which extends essentially over the entire height of the passage and which generates an emerging air curtain, so that the passage is shielded by the air curtain when the door is open becomes. This air curtain device serves to keep the energy losses caused by the open door as low as possible. The energy losses when the door is open are based on the different temperature and climate values in the exterior and interior of the door.

It is known from the published documents DE 102 24 527 AI, DE 102 24 528 AI and from the patent DE 100 18 868 C2 to provide various types of door devices with the air curtain devices already mentioned above. In the aforementioned publications, the special embodiment of the air curtain device is described in connection with the door device. These publications also aim at the functioning and mode of operation of the air curtain devices. Since these door devices are usually automatic doors that can independently open the passage, sensors are also used which detect whether a person wants to go through the passage or to go Time in it. As soon as these sensors deliver a corresponding signal, the passage through the automatic door device is then released.

It is also known to install an anti-theft device in the area of the passage of a door device, by means of which it can be seen that goods which have not been paid for and therefore not unlocked are transported from the secured area to the unsecured area. Time recording or personnel control systems in the passage area of door devices are also known, since the passage still represents a bottleneck through which all people, objects or the like get from one area to another area. A disadvantage of the last-mentioned systems, however, is that they are only in the area of the door device, but are not dependent on the passage of a person or an object through the door. For example, People walk through the door facility without logging into an existing time recording system. This problem arises above all from the separation of the individual systems from the associated door equipment.

The invention is therefore based on the object to develop a door device of the type mentioned in the preamble of claim 1, which not only enables the passage of objects and people, but also identifies people, objects or the like. The handling should be as simple and uncomplicated as possible, so that the identification is achieved solely by passing through the passage of the door device. These objects are achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning.

According to the invention, the door device is provided with at least one additional identification system. This identification system contains at least one sensor unit, a control unit and an output unit, the individual units being connected to one another. This connection does not have to be realized with each other, but can be achieved through a series connection respectively. The connection itself does not necessarily have to be made by an electrical line, but can be realized by an infrared, radio connection system or the like. It is further provided according to the invention that at least one sensor unit of the identification system is integrated in the housing of the air curtain device. It does not matter whether the sensor unit is arranged inside the housing of the air curtain device or on the outside of the housing. It is also irrelevant whether the housing of the air curtain device is actually filled with such a device or not. With such a door device it is now possible to identify all persons, objects or other things that get through the passage of the door. This prevents the previously known goods security, time recording, inventory control and personnel control systems from being deliberately avoided. For example, a person cannot consciously run the time recording system as soon as he has left the inner door area through the passage. Also, as with the external goods security systems that have been installed in front of the door device in the interior, goods cannot pass undetected from the interior to the exterior of the door. It is also advantageous that the sensors required for securing the goods are no longer in the way of additional stirrups or pillars in the area in front of the door device. This is important on the one hand for the safety of people inside the door device in the event of a fire alarm or the like and on the other hand for the cleaning staff who have to drive around the additional posts and brackets with their sweepers. Also, building planners and architects no longer have to pay attention to the fact that there is still additional space required to check goods, time, inventory or inventory

To be able to set up personnel control system. This planning step is therefore completely eliminated, since the systems described above are integrated in the door device. In addition, handling during identification is particularly simplified by the door device according to the invention. For example, only goods must be provided with an anti-theft device, which is thus automatically recognized by the door system's identification system. Even with one Time recording system, it is sufficient that the people simply carry an identity card with them, which is then recognized by the identification system when going through the door device. Such an identification card can of course also be used to enable or deny access to certain people through the door device. The inventory of goods within the door area can also be recorded by a door device, in that the bar code on the goods is recorded by the identification system, and thus all incoming and outgoing goods can be managed by the identification system.

Further developments of the door devices are preferably described in claims 2 to 19.

In a special embodiment of the door device, the air curtain device with the integrated sensor unit is arranged as a door jamb from the door holder. In this embodiment, the air curtain does not move with the door when it is opened or closed. As a result, complex wiring of the air curtain device and the integrated sensor unit can be dispensed with. It is therefore a particularly stable and low-maintenance technical embodiment of the door device. Also, no particularly light materials have to be used, since the air curtain device, as already mentioned, is arranged as a door jamb.

In another embodiment of the door device, the air curtain device with the integrated sensor unit is arranged on the movable door itself. In this embodiment, the efficiency of the air curtain device is particularly high, since the air curtain has a particularly strong shielding effect when the door is opened and closed, and the energy losses can thus be reduced further. When the door is open, the special arrangement of the air curtain device on the door is irrelevant, since the air curtain is so strong that it covers the entire width of the passage can shield. In this respect, the effect of the air curtain device when the door is open is the same as in the previously described embodiment. However, the reliability of the identification system is also increased in the exemplary embodiment described here.

In a further variant, the door device is designed with a one-part or multi-part sliding door and the door holder holds at least one movable door in a longitudinally displaceable manner. In this variant, the air curtain device with the integrated sensor unit can be arranged on the longitudinally displaceable door, which results in the advantages described above. However, the air curtain device should be particularly light so that the total mass of the door with the air curtain device is not too high.

In a further variant, the door device is designed with a single or multi-part wing door and the door holder holds at least one movable door so that it can rotate. Here, the air curtain device with the integrated sensor unit is arranged as a door jamb from the door bracket. As already mentioned, this embodiment is a particularly stable and maintenance-free variant. Part of the sensor unit can also be directly integrated in the wing door.

An additional variant of the door device provides that it is designed as a revolving door, the moveable door being present as an at least two-leaf revolving carousel that rotates about a central axis of rotation in use and the circular cylindrical door holder rotatably accommodates the revolving door. This variant in itself ensures that there is never a direct air exchange between the inside and outside of the door, since the revolving door itself is always in between. On one side of the passage (left or right, depending on how the revolving door rotates), the air curtain device with the integrated sensor unit is provided as a door jamb by the circular cylindrical door bracket. In contrast, on the other side (opposite side) of the passage is the sensor unit in the door jamb available. The entire passage through the identification system is thus recorded. This special arrangement

Air curtain device / sensor unit / door jamb or sensor unit / door jamb can be provided in the entrance area as well as in the exit area of the revolving door. As a result, it is impossible for people, goods or the like to go from outside to inside or vice versa without bypassing the identification system.

In the embodiments described so far, the door (regardless of its embodiment) can also be automatically movable by an additional drive unit, so that it opens and closes the passage independently. On the one hand, this enables further energy costs to be saved, since the door only has to be open when people or goods actually want to pass the passage, and on the other hand, the passage through the door device is made easier, e.g. an adult with a pram or a disabled person does not have to laboriously open the door with their own muscular strength. It goes without saying that the drive unit in the case of a sliding door moves the door in a longitudinally displaceable manner. In the case of a double door, the drive unit turns the door automatically, just as the drive unit turns the carousel on a revolving door.

In a further variant of the door device, the drive unit of the automatic door can be controlled by the output unit of the identification system, whereby the door can be opened or closed depending on the application. This measure makes it possible, for example, to stop the automatically driven carousel of a revolving door and to block the passage as soon as goods that are still provided with an anti-theft device have been recognized by the identification system. It is also possible for people who have been recognized by the identification system but who are not allowed to pass through the door device to remain blocked. The sensor unit of the identification system can contain a multiplicity of sensors which are arranged in sections over the height of the passage in the air curtain device. This measure can ensure, for example, that children who play in the passage area of the door device can be recognized by the sensor unit, so that the door is not accidentally closed. In systems which have been conventional up to now, an infrared sensor is usually arranged in the upper region of the passage, which very often cannot detect children and animals because they are too far away from the sensor. As a result, there is a great risk of accidents in the conventional systems.

It is also conceivable that this sensor unit is equipped with at least one antenna-like sensor, which is arranged essentially over the entire height of the passage in the air curtain device. Such a sensor is generally used in an anti-theft system because it can detect the anti-theft goods according to the radio frequency principle. The signal forwarded by the antenna-like sensor is then detected and evaluated by the control unit, which can trigger various functions, such as Alarm signal, closing the door, control of a video camera, radio signal to the guards or the like.

In a further variant of the door device, it is also provided that the sensor unit contains different sensors which record different measured variables and forward the resulting signals to the control unit for evaluation and processing. This measure also significantly increases the area of application of the door device, since the identification system can not only be used to open and close the automatic door as soon as people or goods want to pass through the passage area, but also at the same time to identify the people and goods passing through are. For example, it is conceivable that goods that are provided with a bar code can be recognized by so-called laser diodes, which in this case are used as sensors. Likewise a person passing through the passage who has an identification card can be recognized by the identification system. Even today it is already conceivable that a person can be recognized by video sensors (ie small video cameras) on the basis of their external appearance and the video signal supplied by an appropriate evaluation algorithm in the control unit.

In a special variant of the door device, the identification system is designed as a goods security system, in which secured goods in the passage area of the door are recognized by the sensor unit and a signal is passed on to the control unit, which evaluates this signal and sends a corresponding alarm signal to the output unit. For this purpose, the goods are provided with an anti-theft device, which is removed when the goods are purchased. However, should, for whatever reason, goods get into the passage area of the door which is still provided with the anti-theft device, the goods with the anti-theft device are recognized by the sensor unit. This supplies a corresponding signal to the control unit, which then has the output unit take appropriate actions, such as alarm signals, close the door, call the security personnel or the like.

Likewise, in a special variant, the identification system can be configured as an inventory system, in which the incoming and outgoing goods in the passage area of the door are recognized by the sensor unit, and the signals generated are passed on to the control unit, which evaluates and processes these signals. So that the sensor unit can clearly recognize the goods, the goods must be provided with a bar code, for example. For very special goods that differ in their outer shape, it is also conceivable that these can be recognized by video sensors based on their outer shape. In a further variant of the door device, the identification system is available as a time recording system, in which the time of incoming and outgoing people in the passage area of the door is recorded depending on the sensor unit people, and the signals generated are passed on to the control unit, which evaluates these signals and further processed. For this purpose, the incoming and outgoing person must carry, for example, a special identification card that is clearly recognized by the sensor unit. This can ensure that the misuse of the time recording system is made significantly more difficult.

Likewise, in a variant of the door device, the identification system can be a person control system, which identifies incoming and outgoing people in the passage area of the door by the sensor unit and the signals generated are passed on to the control unit, which evaluates and processes these signals. This allows special people to pass through the door device and prevents others from doing so. For this purpose, the people can also be equipped with an identification card that is clearly identified by the sensor unit.

At this point it should be mentioned that a combination of the previously mentioned goods security, inventory, time recording and personnel control systems is also possible.

In a further embodiment of the door device, the identification system also contains an input unit which is connected to the control unit, as a result of which an additional security or identification code for the detected signals of the sensor unit can be passed on to the control unit. For example, it may be necessary for a person not only to have an identification card with them to be identified by the sensor unit, but also to additionally enter a number code in the input unit so that the passage is released by the control unit. It is also conceivable in the door devices described that the control unit of the identification system is networked with the air curtain device via a data transmission system and can thereby transmit and receive data, as a result of which active elements, in particular the blower, heater and nozzle of the air curtain device can also be controlled. It is thus possible to forward the data that are recorded by the air curtain device to the control unit of the identification system, which then takes over the entire control task of the door device. Thus, the air curtain device does not have to be provided with its own control device, but it is sufficient that the data recorded by the air curtain device is forwarded to the control unit of the identification system for further processing. This enables a simple technical structure to be implemented by dispensing with a further control device.

It is also conceivable that the identification system also records climate data from the area of the door by means of further sensors and on the

Control unit communicates, whereby the active elements of the

Air curtain device, which itself is connected to the control unit, can be controlled directly. So the identification system also takes over

Task to record all climate data from the area of the door and use it to control the air curtain device.

In a special variant of the door device, the control unit of the identification system is networked with an external central computer via a data transmission system, so that data can thereby be exchanged between the control unit of the identification system and the external central computer. Thus, for example, in the event of a fire alarm, the door of the door device can be opened or closed automatically. It is also possible to monitor and, if necessary, influence all functions of the door device, ie also those of the identification system and the air curtain device, from a central location. Below we explain the invention with reference to the accompanying drawings.

Show it:

1 in front view, a door device in the form of a hinged door, FIG. 2 in perspective view, a door device in the form of a revolving door, FIG. 3 in front view, a door device in the form of a sliding door, FIG. 3a in sectional view the sliding door from FIG. 3 with the door closed and FIG. 3b the same section through the sliding door from FIG. 3, but with the door open.

The door device 10 contains at least one door 11, which is provided for opening and closing a passage 27. The door device 10 further includes a door holder 12 on which the door 11 is movably held so as to open or close the passage 27. In addition, the door device 10 contains at least one vertical air curtain device 30, which extends essentially over the entire height of the passage 27 and which generates an emerging air curtain 33, so that the passage 27 is shielded by the air curtain 33 when the door 11 is open. Such a door device 10 is shown in FIGS. 1 to 3. The special feature of the door device 10 is that it is provided with at least one additional identification system 40, this identification system containing at least one sensor unit 41, a control unit 42 and an output unit 43 which are connected to one another. At least one sensor unit 41 of the identification system 40 is integrated in the vertical air curtain device 30. This measure makes it possible to check people, goods or the like in the passage 27 of the door device 10. The passage 27 continues to represent a bottleneck through which all people and goods pass from the outer area 28 into the inner area 29 in the door device 10. Thus, the location of the passage 27 is extremely suitable for appropriate control make. A goods security system 50 of the conventional type is shown in FIGS. 3, 3a and 3b. As can be clearly seen from FIGS. 3a and 3b, it is possible for people or goods to get behind the goods security system 50 (ie between the system 50 and the wall 25) through the passage 27. This disadvantage is avoided in any case by the special arrangement of the sensor unit 41 of the identification system 40 in the air curtain device 30.

Likewise, there is no additional detection system in the door area of the door device 10. It is therefore possible for the cleaning staff to also keep the door area clean with the cleaning machines. The architects also no longer have to think about an additional detection system and the space required for this when planning the door area.

In Fig. 1 the door device 10 is designed as a wing door 17. The wing doors 17 represent special doors 11 of the door device 10. These wing doors 17 can be pivoted to the side (in the direction of the arrows 18) by means of the handles 14, provided that there is no additional drive unit 24 which automatically opens and closes the wing door 17. In this door device 10, the air curtain device 30 with the integrated sensor unit 41 is provided as a left and right-hand door jamb 13 of the door holder 2. The air curtain device 30 is thus arranged in a stationary manner since it is an integral part of the door device 10. Part of the sensor unit 41, 46 can also be present in the wing doors 17.

If a wing door 17 is now opened, the air curtain device shields the passage 27 through the air curtain 33 emerging from the air outlet opening 31. The air curtain 33 is generated by the blower 32. The sensor unit 41 is provided, for example, as an antenna-like sensor 47 between the blower 32 and the air outlet opening 31. This sensor 47 extends over the entire height of the passage 27. Thus, the entire passage 27 is also monitored by the antenna-like sensor 47. Consequently, neither person or an object from the outer region 28 into the inner region 29 or vice versa that is not detected by the identification system 40. The identification system 40 and essential parts thereof, namely the control unit 42, the output unit 43 and the housing 45 are shown as a black box in the wall 25 in FIG. 1. Of course, the sensor unit 41, which in this case consists of the two left-hand and right-hand antenna-like sensors 47, is also connected to the rest of the identification system 40. How this happens, however, is irrelevant to the invention.

Fig. 2 discloses a door device 10 which is designed as a revolving door 19, in which case the movable door 11 is provided as a two-leaf carousel 19 which rotates around a central axis of rotation 22 in use and accommodates the circular-cylindrical door holder 21 of the revolving door 19. The revolving door 19 rotates in a clockwise direction about the central axis of rotation 22, in accordance with the arrows 23 shown. The emerging air curtain 33 also emerges clockwise from the air curtain device 30 at the location of the air outlet opening 31. Of course, the direction of rotation 23 of the carousel 19 can also run counterclockwise, but then the air curtain 33 must also be directed in reverse, ie the air curtain device 30 must consequently be provided on the other door jamb 13. Sensors 46 of the sensor unit 41 are accommodated in the air curtain device 30 and in the door jamb 13. These sensors are thus arranged to the left and right of the passage 27, so that even with the revolving door 19, each person or object must pass through the detected area of the sensors 46 if he wants to pass through the door device 10. In this embodiment there is also an additional input unit 44, by means of which an additional security or identification code can be passed on to the control unit 42. This security or identification code can then - with the further signals from sensor unit 41 - be evaluated by control unit 42. Depending on the application, access is then released or denied by the door device 10. The input unit 44 can itself be a keyboard, a Magnetic card reader, a video camera, a fingerprint sensor or the like. Contain. It is not shown in FIG. 2 how the input unit 44 and the sensor unit 41, which contain the sensors 46, are connected to the identification system 40.

3 a shows a further embodiment of the door device 10, which contains a sliding door 15. In this exemplary embodiment, the sliding doors 15 are each provided with an air curtain device 30 on their passage side. In the closed state of the doors 15, the air curtain devices 30 thus lie parallel to one another. As a result, the two sensor units 41 of the identification system 40 are almost adjacent to one another. Now people approach the door device 10, the doors 15 can be moved longitudinally by the drive unit 24 in the direction of the arrows 16. As a result, the passage 27 is released by means of the door device 10. It can also be seen here that each person or object must pass through the open passage 27 and thus through the area of the sensor unit 41 in order to get from an outer area 28 into an inner area 29. In this case, the identification system 40 with the control unit 42 and the output unit 43 is arranged in the upper region of the door holder 12. The conventional goods security systems 50 are also shown in FIG. 3.

It can be clearly seen in FIG. 3 a that the conventional article surveillance systems 50 are at a clear distance from the wall 25, so that people or objects can muddle through in the intermediate area between article surveillance systems 50 and wall 25, and thus not from the article surveillance system 50 to be captured. This is not possible with the integrated identification system. The entire door device 10 is attached to the wall 25 with U-shaped door posts 13. There is enough space in the upper region of the door holder 12 to accommodate the drive unit 24 and the essential parts of the identification system 40. 3b, the sliding doors 15 open the passage 27 through the door device 10. In this case, the air curtain devices 30 generate the horizontal air curtains 33, so that the entire passage area 27 is effectively shielded.

It can also be clearly seen from FIGS. 3a and 3b, like the sensor unit in each case

41 is arranged in the air curtain device 30 or the housing. It should be mentioned again that the sensor unit 41 can consist of various sensors 46 and antenna-like sensors 47. The desired measurement data can thus be recorded and sent to the control unit by the sensor unit 41

42 are passed on for further processing. Since the control unit 42 itself can consist of an intelligent circuit, a programmed microprocessor or the like, various possible applications are conceivable. For example, the control unit 42 of the identification system 40 can be networked with an external central computer via a data transmission system. Newer buildings in particular have a so-called control center, which is controlled by a central computer. Thus the central computer can serve e.g. in the event of a fire alarm or an attempted break-in, to open or close the door device 10. This also enables the air curtain device 30 to be controlled with its active elements.

It remains to be noted that the embodiments of the door device 10 shown here are only exemplary implementations of the invention. However, this is not limited to the combinations shown. It is understood that the illustrated components and elements of the invention can also be present in other embodiments and constructions which have properties similar to those which have been described here.
