Description

Die Erfindung betrifft eine manuell betätigbare Karusselldrehtür mit einem zwischen seitlichen Begrenzungswänden um eine vertikale Achse drehbar aufgenommenen, vorzugsweise als mehrflügliges Drehkreuz ausgebildetem Sperrelement und mit einer in Abhängigkeit von der Drehgeschwindigkeit des Sperrelements wirksam werdenden Bremseinrichtung.The invention relates to a manually operated revolving door with one between the side walls preferably rotatably received about a vertical axis blocking element designed as a multi-wing turnstile and with a depending on the speed of rotation of the Locking element effective braking device.

Derartige Karusseldrehtüren sind bereits seit langem bekannt und werden insbesondere in Gebäuden und/oder abgegrenzten Arealen als Personenschleusen eingesetzt.Such revolving revolving doors have been known for a long time and are particularly delimited in buildings and / or Areas used as security gates.

Aus der US-PS 4,976,065 ist in Verbindung mit einer Karusselldrehtür eine Geschwindigkeitssteuereinrichtung zur Überwachung der Drehgeschwindigkeit der Drehtür vorbekannt. Die Geschwindigkeitssteuereinrichtung umfaßt eine Fliehkraftbremse, deren Bremsbacken um feste Lagerachsen einer Bremstrommel gegen die Wirkung einer Rückstellfeder in Abhängigkeit von der Drehgeschwindigkeit ausschwenken und dadurch wirksam werden. From US-PS 4,976,065 is in connection with a revolving door a speed control device for Monitoring of the speed of rotation of the revolving door previously known. The speed control device comprises a centrifugal brake, whose brake shoes around fixed bearing axles Brake drum against the action of a return spring depending swing out of the speed of rotation and thereby be effective.

Ferner ist aus der DE 35 06 740 A1 ein Rotationsdämpfer für Schließantriebe von Schwenktüren, Schiebetüren oder dergleichen vorbekannt, der als Magnetdämpfer ausgebildet ist und einen Elektromagneten mit gepulster Ansteuerung sowie eine Ankerplatte besitzt. Eines der beiden genannten Teile, nämlich der Elektromagnet oder die Ankerplatte, ist drehfest gelagert, das andere Teil hingegen mit dem Türantrieb gekoppelt, und die beiden Teile sind axial gegeneinander beweglich geführt.Furthermore, DE 35 06 740 A1 describes a rotary damper for Closing drives for swing doors, sliding doors or the like previously known, which is designed as a magnetic damper and an electromagnet with pulsed control as well has an anchor plate. One of the two parts mentioned namely the electromagnet or the armature plate is non-rotatable stored, the other part with the door operator coupled, and the two parts are axially against each other flexibly guided.

Demgegenüber soll durch die vorliegende Erfindung eine Karusselldrehtür der eingangs beschriebenen Art und Zweckbestimmung mit einer verbesserten Geschwindigkeitssteuereinrichtung geschaffen werden.In contrast, a revolving door is intended by the present invention the type and purpose described at the beginning with an improved speed control device be created.

Gelöst ist diese Aufgabe dadurch, daß bei der Karusselldrehtür nach dem Oberbegriff des Patentanspruchs 1 das Sperrelement mit einem Bremsmotor als Bremseinrichtung sowie mit Mitteln zum Erfassen der Umdrehungsgeschwindigkeit und/oder der Umdrehungsrichtung des Sperrelementes wirkverbunden ist, welcher Bremsmotor zumindest oberhalb eines vorbestimmten Betrages der erfaßten Umdrehungsgeschwindigkeit und/oder bei einer vorbestimmten Drehrichtung auf die Drehachse des Sperrelements mit einem entgegen der Drehrichtung des Sperrelements gerichteten Drehmoment einwirkt, daß der Bremsmotor mit einer elektronischen Steuerung versehen ist, mittels der die Grenzdrehgeschwindigkeit, ab der die bestimmungsgemäße Wirkung des Bremsmotors einsetzt, und/oder die Umdrehungsrichtung und/oder das Drehmoment, das der Bremsmotor der Drehbewegung des Sperrelements entgegensetzt, einstellbar ist, und daß die elektronische Steuerung von einer vom Bremsmotor erzeugten Spannung mit Strom versorgt wird.This task is solved in that the revolving door according to the preamble of claim 1 Locking element with a brake motor as a braking device as well with means for detecting the speed of rotation and / or the direction of rotation of the locking element operatively connected is which brake motor is at least above one predetermined amount of the detected rotational speed and / or at a predetermined direction of rotation on the Rotation axis of the locking element with a counter to the direction of rotation the locking element acts directed torque, that the brake motor is provided with an electronic control is, by means of which the limit rotational speed from which uses the intended effect of the brake motor, and / or the direction of rotation and / or the torque, that the brake motor opposes the rotary movement of the locking element, is adjustable, and that the electronic Control of a voltage generated by the brake motor Electricity is supplied.

Erfindungsgemäß erfolgt somit eine laufende Erfassung der Umdrehungsgeschwindigkeit des Sperrelements. Bei Überschreitung einer vorbestimmten Grenzdrehgeschwindigkeit des Sperrelements wirkt der Bremsmotor auf das Sperrelement ein und bremst dessen Drehgeschwindigkeit ab. Wird als Folge der Abbremsung die Grenzgeschwindigkeit unterschritten, hört die Bremseinwirkung des Motors auf. Bei geringen Umdrehungsgeschwindigkeiten ist somit ein ungehinderter Personendurchgang durch die Karusselldrehtür gewährleistet.According to the invention, the Speed of rotation of the locking element. If exceeded a predetermined limit rotation speed of the Locking element acts on the brake motor on the locking element and slows down its speed of rotation. As a result the braking speed fell below the limit speed, stops the engine braking. At low rotation speeds is therefore an unhindered passage of people guaranteed by the revolving revolving door.

Mit Hilfe der Erfindung ist es auch möglich, die Drehbewegung zumindest in einer vorbestimmten Richtung zu sperren, indem in der vorbestimmten Drehrichtung der Bremsmotor bereits bei einer geringstmöglichen Drehbewegung, in der entgegengesetzten Drehrichtung jedoch erst bei höheren Umdrehungsgeschwindigkeiten zur Wirkung gelangt. Eine so ausgerüstete Karusselldrehtüranlage kann nur in einer Drehrichtung passiert werden. Dies ist besonders vorteilhaft, weil dadurch auf den Einbau von üblicherweise zu diesem Zweck eingesetzten mechanischen Drehsperren verzichtet werden kann.With the help of the invention it is also possible to use the rotary movement to block at least in a predetermined direction, by the brake motor already in the predetermined direction of rotation with the least possible rotation, in the opposite Direction of rotation, however, only at higher speeds of rotation comes into effect. So equipped Revolving revolving door system can only turn in one direction happen. This is particularly advantageous because thereby on the installation of usually for this purpose used mechanical turnstiles are dispensed with can.

Zur Einstellung der Grenzgeschwindigkeit kann beispielsweise ein stufenlos einstellbares Potentiometer, das vorzugsweise zusammen mit der übrigen Elektronik auf einer Platine angeordnet ist, eingesetzt werden. Ein solches Potentiometer sollte manuell verstellbar sein, damit eine Einstellung der Grenzgeschwindigkeit auch bei abgeschalteter Elektronik möglich ist.For example, to set the limit speed an infinitely adjustable potentiometer, which preferably together with the rest of the electronics on a circuit board is arranged to be used. Such a potentiometer should be manually adjustable so that one setting the limit speed even when the electronics are switched off is possible.

Angesichts der Versorgung der elektronischen Steuerung mit einer vom Bremsmotor erzeugten Spannung mit Strom erübrigt sich eine externe Stromversorgung der Elektronik.Given the supply of the electronic control with a voltage generated by the brake motor with electricity is unnecessary an external power supply for the electronics.

In besonders einfacher und vorteilhafter Weise erfolgt die Ansteuerung des Bremsmotors induktiv. Deshalb ist als Bremsmotor zweckmäßigerweise ein Gleichstrommotor eingesetzt, der beim Erreichen der Grenzgeschwindigkeit von der Elektronik kurzgeschlossen wird und dadurch zu seiner bestimmungsgemäßen Wirkung gelangt. Ein derartiger Aufbau ist besonders betriebssicher und verschleißfrei.This takes place in a particularly simple and advantageous manner Control of the brake motor inductive. Therefore, as Braking motor expediently uses a DC motor, which when the limit speed of the Electronics is short-circuited and thereby to its intended purpose Effect. Such a structure is particularly reliable and wear-free.

Alternativ oder ergänzend zur elektromagnetischen Steuerung des Bremsmotors kann zwischen dem Bremsmotor und der Drehachse des Sperrelements auch eine mechanische Kupplung eingesetzt sein. Vorzugsweise können dabei Kupplungen zum Einsatz kommen, die oberhalb einer vorbestimmten Umdrehungsgeschwindigkeit Kraftschluß herstellen.Alternatively or in addition to electromagnetic control The brake motor can be between the brake motor and the axis of rotation the locking element also uses a mechanical coupling his. Couplings can preferably be used come above a predetermined speed of rotation Establish frictional connection.

Die Wartung der Drehgeschwindigkeitsbegrenzung wird dadurch erleichtert, daß der Bremsmotor beabstandet von der Drehachse des Sperrelements angeordnet und mit der Drehachse über entsprechende Antriebsmittel verbunden ist.The maintenance of the speed limit is thereby relieved that the brake motor spaced from the axis of rotation arranged of the locking element and with the axis of rotation is connected via appropriate drive means.

Als mögliche Antriebsmittel zwischen Bremsmotor und Drehachse kommen dabei Ketten- oder Zahnantriebe in Frage. Es sind jedoch andere Verbindungsmöglichkeiten, wie etwa ein Riementrieb, denkbar. As a possible drive between the brake motor and the axis of rotation chain or toothed drives come into question. It however, there are other connection options, such as a Belt drive, conceivable.

Gemäß einer abermaligen vorteilhaften Weiterbildung ist der Bremsmotor in der Dachkonstruktion der Karusselldrehtür aufgenommen, und somit im Reparaturfalle leicht zugänglich.According to another advantageous development, the Brake motor in the roof structure of the revolving revolving door added, and thus easily accessible in the event of repairs.

Jedoch ist auch die Anordnung im Boden oder im Unterflurbereich der Karusselldrehtüranlage möglich.However, the arrangement is also in the floor or in the underfloor area the revolving revolving door system possible.

Anhand der beigefügten Zeichnung soll nachfolgend ein Ausführungsbeispiel der Erfindung näher erläutert werden. In schematischen Ansichten zeigen:

Fig. 1 zeigt einen Ausschnitt aus einer Karusselldrehtüranlage 10, die im übrigen ein als mehrflügliges Drehkreuz ausgebildetes, um eine vertikale Achse 12 drehbar gelagertes Sperrelement aufweist, das zwischen beabstandet voneinander angeordneten seitlichen Begrenzungswänden aufgenommen und zum Schaffen eines Durchgangsweges manuell um seine Achse drehbar ist.Fig. 1 shows a section of a revolving door system 10, the rest of a multi-wing turnstile trained to be rotatable about a vertical axis 12 has mounted locking element which is spaced between side boundary walls arranged from each other recorded and to create a passage is manually rotatable about its axis.

Die Karusselldrehtüranlage 10 ist mit einer in einer oberseitigen Abdeckung der Karusselldrehtüranlage 10 aufgenommenen Drehgeschwindigkeitsbegrenzung ausgerüstet. Die Abdeckung weist eine aus mehreren, in hier nicht weiter interessierender Weise miteinander verbundenen Profilen bestehende Tragkonstruktion 11 und eine von dieser vertikal in Richtung auf den bestimmungsgemäßen Durchgangsbereich 14 der Karusselldrehtüranlage 10 beabstandete Sichtblende 15 auf.The revolving revolving door system 10 has one in an upper side Cover of the revolving revolving door system 10 added Rotation speed limit equipped. The Cover has one of several, not in here interestingly interconnected profiles existing support structure 11 and one of these vertically towards the intended passage area 14 of the revolving revolving door system 10 spaced apart Screen 15 on.

Die Tragkonstruktion 11 ist mit einer Lageraufnahme 16 versehen, in der das Sperrelement der Karusselldrehtüranlage 10 mittels eines Lagerzapfens 17 um die vertikale Achse 12 drehbar aufgenommen ist. Der Lagerzapfen 17 erstreckt sich dabei von der Lageraufnahme 16 durch eine Öffnung in der Sichtblende 15 hindurch und ist auf der der Tragkonstruktion 11 abgewandten Seite der Sichtblende 15 mit einer Befestigungsplatte 19 versehen, die in hier ebenfalls nicht weiter interessierender Weise zur Aufnahme von Drehtürflügeln bestimmt ist.The support structure 11 has a bearing seat 16 provided in the locking element of the revolving door system 10 by means of a bearing pin 17 around the vertical Axis 12 is rotatably received. The bearing pin 17 extends yourself from the bearing holder 16 by a Opening in the screen 15 and is on the the support structure 11 facing away from the screen 15 provided with a mounting plate 19 which in here also of no further interest Inclusion of revolving door leaves is intended.

Zwischen der Tragkonstruktion 11 und der Sichtblende 15 ist auf dem Lagerzapfen 17 ein Kettenrad 20 aufgenommen und drehfest mit dem Lagerzapfen verbunden. Das Kettenrad 20 dient der Wirkverbindung der Drehachse 12 des Sperrelements mit dem im folgenden beschriebenen motorischen Bremsantrieb 23.Between the support structure 11 and the screen 15 a sprocket 20 is received on the journal 17 and non-rotatably connected to the bearing journal. The sprocket 20 is used for the operative connection of the axis of rotation 12 of the Locking element with the motor described below Brake drive 23.

Der Bremsantrieb 23 ist auf einer Konsole 24 aufgenommen, die beabstandet von der Drehachse 12 des Sperrelements angeordnet und mit einem vorstehenden Halteabschnitt 25 mittels Schraubverbindungen 26 an einem Profil 27 der Tragkonstruktion 11 befestigt ist. Der Bremsantrieb 23 umfaßt einen Elektromotor 30 und eins Steuerungselektronik 31, die auf der Konsole 24 aufgenommen sind. Ferner ist an der Konsole eine mit dem Elektromotor 30 in nicht dargestellter Weise in Antriebsverbindung stehende Antriebswelle 32 drehbar gelagert. Auf der Antriebswelle 32, die parallel zur Drehachse 12 des Sperrelements verläuft, ist ein Kettenrad 34 drehfest aufgenommen, das mit dem drehfest mit der Drehachse 12 des Sperrelements verbundenen Kettenrad 20 fluchtet. Auf den beiden Kettenrädern 20, 34 ist eine Antriebskette 35 geführt. Mittels dieser Antriebskette 35 besteht eine direkte Wirkverbindung zwischen der Drehachse 12 des Sperrelements und dem Motor 30.The brake drive 23 is received on a bracket 24, which are spaced from the axis of rotation 12 of the locking element and with a protruding holding portion 25 by means of Screw connections 26 on a profile 27 of the supporting structure 11 is attached. The brake drive 23 comprises an electric motor 30 and control electronics 31, which are recorded on the console 24. Further is not on the console with the electric motor 30 in shown in the drive connection drive shaft 32 rotatably mounted. On the drive shaft 32, which is parallel to the axis of rotation 12 of the locking element runs, a sprocket 34 is rotatably received, the with the rotationally fixed with the axis of rotation 12 of the locking element connected sprocket 20 is aligned. On the two sprockets 20, 34, a drive chain 35 is guided. By means of this drive chain 35 there is a direct one Active connection between the axis of rotation 12 of the locking element and the engine 30.

Wenn das Sperrelement der Karusselldrehtüranlage 10 in einer vorgegebenen Drehrichtung durch manuelle Betätigung in Drehung versetzt wird, wird diese Drehbewegung über den aus dem drehfest mit der Drehachse 12 verbundenen Kettenrad 20, dem mit dem Motor 30 in Antriebsverbindung stehenden Kettenrad 34 und die Antriebskette 35 gebildeten Umschlingungstrieb auf den Motor 30 übertragen. Die Drehbewegung der mit dem Motor 30 in Wirkverbindung stehenden Antriebswelle 33 wird von einer Meßelektronik erfaßt und der erfaßte Wert an die Steuerelektronik 31 übermittelt. Die Steuerelektronik 31 vergleicht den übermittelten Wert mit einer voreingestellten Grenzumdrehungsgeschwindigkeit. Wenn die aktuelle Drehgeschwindigkeit der Antriebswelle 32 die vorgegebene Grenzumdrehungsgeschwindigkeit überschreitet, ergeht von der Steuerungselektronik 31 ein Steuerbefehl an den Motor 30.If the locking element of the revolving door system 10 in a predetermined direction of rotation by manual operation is set into rotation, this rotary movement over the from the rotationally fixed to the axis of rotation 12 Sprocket 20, which is drivingly connected to the motor 30 stationary sprocket 34 and drive chain 35 formed belt drive transferred to the motor 30. The rotational movement of the motor 30 in operative connection standing drive shaft 33 is from measuring electronics recorded and the recorded value to the control electronics 31 transmitted. The control electronics 31 compares the transmitted value with a preset limit rotation speed. If the current rotation speed the drive shaft 32 the predetermined limit speed of rotation exceeds, comes from the control electronics 31 a control command to the motor 30.

Der Motor 30 ist als Gleichstrommotor mit Permanenterregung ausgebildet. Ein im Falle einer Überschreitung der vorgegebenen Grenzumdrehungsgeschwindigkeit von der Steuerelektronik 31 ausgelöste Steuerbefehl bewirkt, daß der Motor 30 kurzgeschlossen wird mit der Folge, daß der über den Umschlingungstrieb übertragenen Drehbewegung ein der Drehrichtung entgegengerichtetes Bremsmoment wirkt. Angesichts dieses Gegendrehmomentes wird die Drehbewegung der mit dem Motor in Wirkverbindung stehenden Antriebswelle 32 und damit auch die Drehbewegung des Sperrelements der Karusselldrehtüranlage solange gebremst, wie die aktuelle Drehgeschwindigkeit größer ist als die vorgegebene Grenzumdrehungsgeschwindigkeit.The motor 30 is a DC motor with permanent excitation educated. One in case of exceeding the predetermined speed of revolution from the Control electronics 31 triggered control command causes the motor 30 is short-circuited, with the result that the rotary motion transmitted via the belt drive braking torque acting in the opposite direction. In view of this counter torque, the rotary motion the drive shaft that is operatively connected to the motor 32 and thus also the rotary movement of the locking element the revolving door system is braked as long as the current speed of rotation is greater than the specified one Limit rotation speed.

Das durch das Kurzschließen des Motors 30 ausgelöste Bremsmoment ist abhängig von der Drehgeschwindigkeit und umso stärker, je höher die Drehgeschwindigkeit ist. Wenn die aktuelle Drehgeschwindigkeit auf die vorbestimmte Grenzumdrehungsgeschwindigkeit bzw. unter diese absinkt, ergeht von der Steuerungselektronik 31 ein erneuter Steuerbefehl an den Motor 30, aufgrund dessen der Kurzschluß aufgehoben wird. Als Folge davon entfällt die Bremswirkung des Motors 30 und das Sperrelement der Drehtüranlage 10 ist dann ohne die Einwirkung eines bremsenden Gegendrehmomentes betätigbar.The braking torque triggered by short-circuiting the motor 30 depends on the speed of rotation and all the more stronger, the higher the speed of rotation. If the current rotational speed to the predetermined limit rotational speed or falls below this, a new control command from the control electronics 31 to the motor 30, due to which the short circuit will be annulled. As a result, the braking effect no longer applies of the motor 30 and the locking element of the revolving door system 10 is then without the action of a braking counter torque actuated.

Die Drehtüranlage 10 ist für die Betätigung des Sperrelements in einer Drehrichtung ausgelegt. Demgemäß ist die Steuerungselektronik 31 so eingestellt, daß die Grenzumdrehungsgeschwindigkeit für eine Sperrelement-Drehung in Gegenrichtung zur vorbestimmten Drehrichtung bei Null liegt. Eine etwaige Drehung des Sperrelementes entgegen der vorbestimmten Drehbewegung wird elektronisch erfaßt und führt dazu, daß mittels eines von der Steuerungselektronik 31 ausgehenden Steuerbefehls der Motor 30 kurzgeschlossen wird und mithin einer Drehbewegung entgegen der vorgegebenen Richtung ein Bremsmoment entgegenwirkt. Das Sperrelement kann somit nicht oder nur mit erheblichem Kraftaufwand entgegen der vorbestimmten Drehrichtung betätigt werden. Ein Passieren der Karusselldrehtüranlage entgegen der vorbestimmten Drehrichtung des Sperrelementes wird auf diese Weise wirkungsvoll unterbunden.The revolving door system 10 is for the actuation of the locking element designed in one direction of rotation. Accordingly the control electronics 31 set so that the Limit rotation speed for a blocking element rotation in the opposite direction to the predetermined direction of rotation is at zero. Any rotation of the locking element counter to the predetermined rotary motion is electronic detects and leads to the fact that by means of one of the Control electronics 31 outgoing control command of the Motor 30 is short-circuited and therefore a rotary movement a braking torque against the specified direction counteracts. The locking element can not or only with considerable effort against the predetermined Direction of rotation are actuated. Passing the Revolving revolving door system against the predetermined direction of rotation the locking element is effective in this way prevented.
