Abstract

The drive system for a closing element like a gate, door, roller blind or window, has a motor, a sensor to assess the position of the closing element, an operating unit for authorised personnel and a control unit. The motor exerts a closing force that depends on the position or change of position of the closing element. When the element is fully closed, no more force is generated. As soon as it has reached a certain position in the opening direction, the force increases to a maximum value. When the element closes, the force is adjusted to give a soft closing process.

Description

Die Erfindung betrifft ein Antriebssystem mit einem Verschließelement, vorzugsweise für Tore, Türen, Rolläden oder Fenster.The invention relates to a drive system with a closing element, preferably for gates, doors, shutters or windows.

Angetriebene Verschließelemente bieten den Vorteil, daß sie über eine Fernsteuerung ansteuerbar sind. Im Fall von angetriebenen Garagentoren können diese beispielsweise bequem vom Auto aus durch eine Fernsteuerung geöffnet oder geschlossen werden.Driven closing elements offer the advantage that they have a remote control can be controlled. In the case of powered Garage doors, for example, can be conveniently accessed from the car can be opened or closed by a remote control.

Ein Nachteil von angetriebenen Verschließelementen besteht allerdings darin, daß diese in der Regel nur durch die selbsthemmende Wirkung des Antriebssystems gegen unbefugtes Öffnen gesichert sind. Zusätzliche mechanische Verschlußsysteme, wie z.B. Schlösser mit Verriegelungsbolzen, bieten zwar in Ergänzung zu der selbsthemmenden Wirkung einen ausreichenden Schutz, führen allerdings zu einer aufwendigen Konstruktion und zu einer komplizierten Handhabung beim Verschließen und Öffnen des Verschließelements.However, there is a disadvantage of driven closing elements in that these are usually only through the self-locking Effect of the drive system secured against unauthorized opening are. Additional mechanical locking systems, e.g. Castles with locking bolts, offer in addition to the self-locking effect provide adequate protection, however a complex construction and a complicated one Handling when closing and opening the closing element.

Aufgabe der Erfindung ist es daher, für ein angetriebenes Verschließelement zusätzliche Sicherungsmaßnahmen gegen unbefugtes Öffnen mit einem geringen konstruktiven Aufwand vorzusehen.The object of the invention is therefore for a driven closing element additional security measures against unauthorized persons To be opened with little design effort.

Erfindungsgemäß wird diese Aufgabe durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.According to the invention, this object is achieved by the in claim 1 listed features solved.

Die erfindungsgemäße Lösung führt dazu, daß bei dem Versuch, das Verschließelement zu öffnen, dieses mit einer Schließkraft als Gegenkraft beaufschlagt wird.The solution according to the invention leads to the fact that when trying to Closing element to open this with a closing force as Opposing force is applied.

Der Vorteil des erfindungsgemäßen Antriebssystems besteht insbesondere darin, daß eine zusätzliche elektronische Überwachung des Schließelements erfolgt und daß ein aktives Schließen des Verschließelements bei einem Einbruchsversuch möglich ist. Die Sicherheit des angetriebenen Verschließelements kann somit durch einfache konstruktive Maßnahmen wirksam erhöht werden.The advantage of the drive system according to the invention is in particular that additional electronic monitoring of the Closing element takes place and that an active closing of the closing element is possible in the event of an attempted break-in. The security of the driven closing element can thus simple constructive measures can be effectively increased.

Seinem grundsätzlichen Aufbau nach benötigt das erfindungsgemäße Antriebssystem einen Motor zum Antreiben des Verschließelements, einen Positionsgeber zum Erfassen bestimmter Positionen des Verschließelements und eine Steuereinheit, die die Signale des Positionsgebers verarbeitet und die den Motor ansteuert. Bei dem Motor handelt es sich zweckmäßigerweise um einen Elektromotor, der in seiner Drehrichtung umschaltbar ist und der über ein Untersetzungsgetriebe und eine entsprechende Mechanik das Verschließelement antreibt. Das Antriebssystem weist außerdem eine Bedieneinheit auf, die es befugten Personen erlaubt, das Verschließelement zu öffnen oder zu schließen. Diese Bedieneinheit kann zum Beispiel einen Schalter umfassen, der mit einem Schlüssel oder auch mit einer geeigneten Fernbedienung betätigt wird.The basic structure of the invention requires Drive system a motor for driving the closing element, a position sensor for detecting certain positions of the closing element and a control unit that receives the signals from the position transmitter processed and which controls the motor. In which Motor is expediently an electric motor, which can be switched in its direction of rotation and which has a reduction gear and a corresponding mechanism the closing element drives. The drive system also has an operating unit on, which allows authorized persons, the closing element to open or close. This control unit can be used for Example include a switch with a key or is also operated with a suitable remote control.

Nach einer bevorzugten Ausführungsform ist vorgesehen, daß der Motor bei vollständig geschlossenem Verschließelement keine Schließkraft ausübt, um hierdurch den Motor nicht unnötig zu belasten. Sobald das Verschließelement allerdings über eine bestimmte Position hinaus geöffnet wird, wird die maximale Schließkraft von dem Motor auf das Verschließelement ausgeübt. In dieser Konfiguration kann der Motor durch einfaches Ab- bzw. Umschalten angesteuert werden.According to a preferred embodiment it is provided that the Motor when the closing element is completely closed none Exerts clamping force so as not to unnecessarily close the motor strain. As soon as the closing element has a certain Position is opened, the maximum closing force exerted by the motor on the closing element. In this The motor can be configured by simply switching it off or on can be controlled.

Nach einer weiteren bevorzugten Ausführungsform ist vorgesehen, daß die Schließkraft bei Rückkehr des Verschließelements in dessen Schließposition in Abhängigkeit von der Positionsänderung des Verschließelements gesteuert wird. Hierbei steht nicht mehr die Steuerung der Schließkraft, sondern die Regelung der Schließgeschwindigkeit im Vordergrund. Während also bei unbefugtem Öffnen möglichst eine große Schließkraft als Gegenkraft erzeugt werden soll, soll beim Schließen des Verschließelements eine geringe Schließgeschwindigkeit vorliegen, um so eine Beschädigung des Verschließelements durch einen zu starken Aufprall gegen die Endanschläge zu vermeiden.According to a further preferred embodiment, that the closing force in the closing element when it returns Closed position depending on the change in position of the Closing element is controlled. This is no longer the Control of the closing force, but the regulation of the closing speed in the foreground. So while unauthorized Opening creates as large a closing force as possible as a counterforce should be a when closing the closing element slow closing speed to avoid damage of the closing element due to an excessive impact against the Avoid end stops.

Der Positionsgeber kann vorzugsweise aus Schaltelementen bestehen, die durch das Verschließelement an geeigneten Positionen betätigt werden. Zusätzlich kann der Positionsgeber einen Inkrementalgeber umfassen, der durch den Motor angetrieben wird. In Verbindung mit zwei Schaltelementen, die die Endpositionen des Verschließelementes detektieren, kann mit dem Inkrementalgeber die momentane Position des Verschließelements innerhalb der Auflösungsgenauigkeit der abgegebenen Impulse bestimmt werden. Hierdurch ist es möglich, beliebige Kraftverläufe der Schließkraft in Abhängigkeit der Position des Verschließelements vorzugeben.The position transmitter can preferably consist of switching elements, through the closing element in suitable positions be operated. The position encoder can also be an incremental encoder include driven by the engine. In Connection with two switching elements that determine the end positions of the Detect the closing element with the incremental encoder the current position of the closing element within the resolution accuracy of the delivered pulses can be determined. Hereby it is possible to in any force curves of the closing force Depending on the position of the closing element.

Nach einer weiteren bevorzugten Ausführungsform ist vorgesehen, daß im Schließzustand des Verschließelements bei Überschreiten einer vorgegebenen Position des Verschließelements eine Alarmanlage ausgelöst wird. Hierbei ist es denkbar, daß eine bereits installierte oder noch zu installierende Alarmanlage eines Gebäudes benutzt wird, so daß das Antriebssystem ein entsprechendes Alarmsignal an diese Alarmanlage weiterleitet. Es ist aber auch denkbar, daß eine Alarmanlage im Antriebssystem direkt integriert ist, so daß eine autarke Alarmsicherung des Verschließelements erfolgt.According to a further preferred embodiment, that in the closed state of the closing element when exceeded a predetermined position of the closing element an alarm system is triggered. It is conceivable that an already installed or a building's alarm system to be installed is used so that the drive system an appropriate alarm signal forwards to this alarm system. But it is also conceivable that an alarm system is integrated directly into the drive system is, so that a self-sufficient alarm protection of the closing element he follows.

Vorteilhaft läßt sich das erfindungsgemäße Antriebssystem verwenden für Verschließelemente wie Tore, Türen, Rolläden oder Fenster, wobei die Verschließbewegung zum Beispiel aus einer Schiebe-, Dreh- oder Schwingbewegung bestehen kann.The drive system according to the invention can advantageously be used for locking elements such as gates, doors, roller shutters or windows, the closing movement, for example, from a sliding, Rotary or oscillating movement can exist.

Als Ausführungsbeispiel der Erfindung wurde ein Überkopf-Garagentor herangezogen, das nachstehend anhand der Zeichnung näher erläutert wird. In dieser zeigt

As an embodiment of the invention, an overhead garage door was used, which is explained in more detail below with reference to the drawing. In this shows
Fig. 1
a schematic representation of an overhead movable garage door with a block diagram of the drive system according to the invention and
Fig. 2
an enlarged block diagram of the drive system according to the invention.

Das Garagentor aus Fig. 1 weist zwei vertikale Streben 1 auf, an deren oberen Ende sich zwei Laufschienen 2 anschließen, in denen das Torblatt 3 geführt ist. Das Torblatt 3 ist weiterhin mit einem nicht dargestellten Gestänge an die Streben 1 angelenkt, so daß sich das Torblatt mit einer Überkopfbewegung öffen und schließen läßt. Außerdem sind Ausgleichsfedern vorgesehen, die das Eigengewicht des Torblattes während der Bewegung weitgehend kompensieren und die das Torblatt in seinen Endstellungen definiert halten. Das mit 4 bezeichnete Antriebssystem besteht insgesamt aus einem Schleppkettenantrieb mit einer Schleppkette 5, an der das Torblatt 3 angelenkt ist und die über die Umlenkrolle 6 sowie über eine nicht dargestellte Antriebsrolle geführt ist. Die Antriebsrolle befindet sich in dem Antriebsaggregat 7 und wird über ein Getriebe durch den Elektromotor 9 angetrieben. Ebenfalls durch den Elektromotor 9 angetrieben wird ein Inkrementalgeber 8, der nach einer bestimmten Anzahl von Umdrehungen jeweils einen Impuls an die Steuereinheit 10 abgibt. In Verbindung mit Schaltelementen, die durch das Torblatt 3 in dessen beiden Endstellungen, also in vertikaler und in horizontaler Stellung, betätigt werden, wertet die Steuereinheit 10 die Impulse des Impulsgebers aus. Auf den Inkrementalgeber kann gegebenenfalls auch verzichtet werden, wenn entsprechende Schaltelemente so montiert werden, daß die Steuereinheit die nötigen Positionsinformationen erhält. Das Ausgangssignal der Steuereinheit 10 führt zu einem Verstärker 11, der dem Elektromotor 9 die notwendige Leistung zuführt.The garage door from FIG. 1 has two vertical struts 1 whose upper end is followed by two tracks 2, in which the door leaf 3 is guided. The door leaf 3 is still with a linkage, not shown, articulated to the struts 1, so that the door leaf opens and closes with an overhead movement leaves. In addition, compensating springs are provided, which Largely compensate for the dead weight of the door leaf during the movement and which defines the door leaf in its end positions hold. The drive system designated 4 exists overall from a drag chain drive with a drag chain 5, on the the door leaf 3 is articulated and the pulley 6 and is guided over a drive roller, not shown. The driving role is located in the drive unit 7 and is about a gear driven by the electric motor 9. Likewise an incremental encoder 8 is driven by the electric motor 9, the one after a certain number of revolutions Outputs pulse to the control unit 10. In connection with switching elements, through the door leaf 3 in its two end positions, that is, actuated in the vertical and in the horizontal position are, the control unit 10 evaluates the pulses of the pulse generator out. If necessary, the incremental encoder can also be omitted be, if appropriate switching elements are mounted so that the control unit receives the necessary position information. The Output signal of the control unit 10 leads to an amplifier 11, which supplies the necessary power to the electric motor 9.

Fig. 2 zeigt die elektronischen Komponenten des Antriebssystems. Demnach besteht die Steuereinheit 10 aus einem Microcontroller. Neben den Impulsen des Inkrementalgebers 8 und gegebenenfalls weiteren Schaltelementen wertet der Microcontroller 10 außerdem das Signal eines nicht näher dargestellten Empfängerteils einer Funkfernsteuerung aus, mit der befugte Personen das Garagentor öffnen oder schließen können.2 shows the electronic components of the drive system. Accordingly, the control unit 10 consists of a microcontroller. In addition to the pulses of the incremental encoder 8 and if necessary The microcontroller 10 also evaluates further switching elements the signal of a receiver part, not shown Radio remote control off, with authorized persons the garage door can open or close.

Gelangt an den Microcontroller ein Befehl zum Öffnen des Garagentors 3, so wird in an sich bekannter Weise über den Verstärker 11 der Elektromotor 9 angesteuert. Bei Erreichen der Endstellung, die durch einen Endschalter oder auch durch entsprechendes Aufintegrieren der Impulse des Inkrementalgebers 8 erkannt wird, wird der Motor wieder ausgeschaltet. Wenn im anderen Fall ein Befehl zum Schließen des Garagentores an den Microcontroller gelangt, so ist der Funktionsablauf entsprechend.The microcontroller receives a command to open the garage door 3, the amplifier 11 the electric motor 9 is controlled. When the end position is reached, by a limit switch or by appropriate integration the pulses of the incremental encoder 8 are recognized, the engine is switched off again. If otherwise a Command to close the garage door to the microcontroller the functional sequence is corresponding.

Die erfindungsgemäße Funktion des Antriebssystems setzt ein, wenn das Garagentor geschlossen ist. Zweckmäßigerweise wird in vollständig geschlossener Position des Torblatts noch keine Schließkraft ausgeübt, um so den Motor nicht unnötig zu belasten. Sobald der Microcontroller 10 allerdings über den Inkrementalgeber 8 oder auch über entsprechende Positionsschalter eine Position des Garagentores detektiert, die über eine zulässige Position hinausgeht, wird der Motor derart angesteuert, daß auf das Garagentor eine Schließkraft wirkt. Je nach Motortyp und Ansteuerschaltung kann dabei die Schließkraft in Abhängigkeit von der Position oder auch von der Positionsveränderung des Garagentors variieren.The function of the drive system according to the invention begins when the garage door is closed. Conveniently, in full closed position of the door leaf still no closing force exercised so as not to put unnecessary strain on the engine. As soon as the microcontroller 10, however, via the incremental encoder 8 or a position of the Detects garage doors that go beyond a permissible position the motor is controlled so that the garage door a closing force acts. Depending on the motor type and control circuit can the closing force depending on the position or also vary from the position change of the garage door.

Die einfachste Möglichkeit besteht darin, daß die Schließkraft ab einer bestimmten Position auf einen Maximalwert, der dem maximalen Stillstandsmoment des Motors entspricht, eingestellt wird. Der Motor kann in dieser Form durch einfaches An- bzw. Umschalten angesteuert werden.The simplest way is that the closing force decreases a certain position to a maximum value that corresponds to the maximum Standstill torque of the motor corresponds, is set. The motor can be switched on and off in this form can be controlled.

Zusätzlich kann bei der Rückkehr des Torblatts in dessen Schließposition vorgesehen sein, daß die Schließkraft als Steuergröße einem Sollverlauf der Positionsänderung, also der Rückkehrgeschwindigkeit in die Stillstandsposition, folgt. Hierdurch wird ein sanftes Schließen des Torblatts bewirkt. Dies kann insbesondere dann erforderlich sein, wenn eine unbefugte Person das Torblatt zunächst zu öffnen versucht und nach Aktivieren der maximalen Schließkraft das Tor plötzlich wieder freigibt.In addition, when the door leaf returns to its closed position be provided that the closing force as a control variable a target course of the change in position, that is, the return speed to the standstill position follows. This will causes the door leaf to close gently. In particular, this can then be required if an unauthorized person checks the door leaf first tried to open and after activating the maximum Closing force suddenly releases the gate again.
