Abstract

The security device, for a roller shutter having profile rails (5) supported between vertical guide rails, has contactless switch sensors (9,10) for operation of an alarm circuit contained in a housing (8) within one of the guide rails, activated by sources (13,14) attached to selected profile rails (51,52). The switch sensors (9,10) are provided by a pair of vertically spaced magnetic switch elements or switch contacts, attached to the outside of the alarm circuit housing (8) and activating the release stage for the alarm circuit when both sensors are moved simultaneously out of range of the corresponding sources (13,14), attached to 2 different profile rails (51,52), indicating forced opening of the roller shutter.

Description

Die Erfindung betrifft eine Sicherungseinrichtung für einen Rolladen aus ineinanderhängenden, lüftbaren Profilleisten, die in senkrechten Führungsschienen laufen, wobei ein Sensor eines berührungslos arbeitenden Schalters in einem eine Alarmschaltung enthaltenden Gehäuse an einer Führungsschiene und ein Geber für den Sensor an der in herabgelassenem Zustand des Rolladens dem Sensor gegenüberstehenden Profilleiste angeordnet ist.The invention relates to a securing device for a roller shutter made of interlocking, ventable profile strips that run in vertical guide rails, with a sensor of a non-contact operating switch in a housing containing an alarm circuit on a guide rail and a sensor for the sensor opposite the sensor in the lowered state of the roller shutter Profile bar is arranged.

Anwendungsgebiet der Erfindung sind Rolladen mit lüftbaren Profilleisten, wobei die Rolladenprofile aus Holz, Kunststoff, Metall, insbesondere Aluminum sein können. Die Rolladen können motorbetrieben oder handbetrieben sein.Field of application of the invention are roller shutters with ventable profile strips, the roller shutter profiles made of wood, plastic, metal, especially aluminum. The shutters can be motor operated or be hand operated.

Eine Sicherungseinrichtung der gattungsgemäßen Art ist aus der DE 77 35 191 U1 bekannt, bei der berührungslos arbeitende Schalter unten oder oben an der Führungsschiene angeordnet sein können. Sobald die Profile des Rolladens aus dem Schaltbereich des jeweiligen Sensors herausbewegt werden, wird ein Alarm ausgelöst. Da diese Sicherungseinrichtung ein befugtes Öffnen des Rolladens und ein unbefugtes Hochschieben nicht unterscheiden kann, ist vor einem befugten Öffnen jeweils eine Abschaltung der Sicherungseinrichtung erforderlich. Dieses ist aufwendig und führt zu Problemen.A safety device of the generic type is known from DE 77 35 191 U1, at the non-contact switch can be arranged at the bottom or top of the guide rail. As soon as the roller shutter profiles are moved out of the switching range of the respective sensor, an alarm is triggered. As this security device an authorized opening of the roller shutter and a cannot distinguish between unauthorized pushing up, a shutdown before an authorized opening the safety device required. This is complex and leads to problems.

Aufgabe der Erfindung ist die Bereitstellung einer Sicherungseinrichtung, die selbsttätig ein unbefugtes Hochschieben von einem befugten Öffnen unterscheidet.The object of the invention is to provide a security device that automatically an unauthorized Pushing up differs from authorized opening.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Gehäuse zwei in vertikalem Abstand angeordnete Sensoren enthält, daß zwei Geber an entpsrechend ausgewählten Profilleisten sitzen und daß eine Auslösestufe der Alarmschaltung dann anspricht, wenn beide Geber gleichzeitig aus dem Schaltbereich des zugehörigen Sensors herausbewegt werden.This object is achieved according to the invention in that the housing two at a vertical distance arranged sensors contains that two sensors sit on appropriately selected profile strips and that a trigger stage of the alarm circuit responds when both encoders from the Switching range of the associated sensor can be moved out.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die Alarmschaltung auf das unbefugte Hochschieben des Rolladens unter Alarmgabe anspricht und ein ordnungsgemäßes Hochziehen davon unterscheidet. The invention differs from the prior art in that the alarm circuit to the unauthorized pushing up of the roller shutter responds with alarm and proper lifting differs from it.

Eine problemlose und empfindliche Sicherung wird dadurch erreicht, daß die Sensoren magnetisch beeinflußbare Schaltelemente oder Schaltkontakte sind. Die Kontakte können auf ein statisches Magnetfeld oder auf eine elektromagnetische Beeinflussung ansprechen.A problem-free and sensitive fuse is achieved in that the sensors are magnetic switch elements or switch contacts that can be influenced. The contacts can be on a static Magnetic field or respond to electromagnetic interference.

Bei ordnungsgemäßem Hochziehen des Rolladens wird eine Alarmauslösung dadurch vermieden, daß eine Alarmauslösung unterbleibt, wenn der obere Geber aus dem Wirkungsbereich des zugehörigen Sensors bewegt wird.If the roller shutter is raised properly, an alarm is avoided by that an alarm is not triggered if the upper encoder is out of the effective range of the associated Sensor is moved.

Eine automatische Einschaltung der Sicherungseinrichtung beim Herablassen des Rolladens wird dadurch erreicht, daß beim Herablassen des Rolladens die Auslösestufe durch aufeinanderfolgendes Wirksamwerden der Geber eingeschaltet wird.An automatic activation of the safety device when lowering the roller shutter is achieved in that when the roller shutter is lowered, the trigger stage by successive The encoder becomes effective.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert, in der darstellen:

  • Fig. 1 eine schematische Gesamtansicht eines geschlossenen Rolladens mit Sicherungseinrichtung,
  • Fig. 2 einen Ausschnitt des Rolladens während des Hochziehens,
  • Fig. 3 einen Ausschnitt des Rolladens während des Hochschiebens und
  • Fig. 4 ein Blockschaltbild der Alarmschaltung.
    • An embodiment of the invention is explained with reference to the drawing, in which:
  • 1 is a schematic overall view of a closed roller shutter with safety device,
  • 2 shows a section of the roller shutter during pulling up,
  • Fig. 3 shows a section of the roller shutter during the pushing up and
  • Fig. 4 is a block diagram of the alarm circuit.

    • Fig. 1 zeigt schematisch einen Fensterrahmen 1 mit einem Rolladenkasten 2, in dem auf einer Wickelwelle 3 mit einem elektrischen oder meachnischen Antrieb 4 ein Rollandenpanzer aus Profilleisten 5 aufwickelbar ist. Die Profilleisten 5 sind in vertikalen Führungsschienen 6 des Fensterrahmens 1 oder Fenstergewändes geführtFig. 1 shows schematically a window frame 1 with a roller shutter box 2, in which on a Winding shaft 3 with an electrical or mechanical drive 4 a rolland armor made of profile strips 5 can be wound up. The profile strips 5 are in vertical guide rails 6 of the window frame 1 or Window robe led

    Im mittleren oder oberen Bereich einer Führungsschiene 6 ist ein Gehäuse 8 angeordnet. Das Gehäuse 8 enthält nach dem Blockschaltbild der Fig. 4 zwei Sensoren 9, 10, eine Auslösestufe 11, eine Alarmschaltung 12 sowie eine nicht dargestellte Energieversorgung in Form einer Batterie.A housing 8 is arranged in the middle or upper region of a guide rail 6. The housing According to the block diagram of FIG. 4, 8 contains two sensors 9, 10, one trigger stage 11, one Alarm circuit 12 and an energy supply, not shown, in the form of a battery.

    Dem Gehäuse 8 gegenüberstehend sind auf Profilleisten 51, 52 zwei Geber 13, 14 angeordnet, die auf die Sensoren 9, 10 ausgerichtet sind. Im Einzelnen ist die Anordnung so getzroffen, daß bei herabgelassenem und auf Block stehendem Rolladenpanzer die Geber 13, 14 den Sensoren 9, 10 genau gegenüberstehen bzs. im Wirkungsbereich der Sensoren sind, so daß die Sensoren ansprechen.Opposite the housing 8, two encoders 13, 14 are arranged on profile strips 51, 52 which are aligned with the sensors 9, 10. In detail, the arrangement is such that, when the floor is lowered and the shutter 13, 14 on the block of the roller shutter curtain facing the sensors 9, 10 exactly resp. are in the effective range of the sensors so that the sensors respond.

    Nach dem Einbau der Sicherungseinrichtung in der beschriebenen Weise ist dieselbe immer empfindlich. Beim Herablassen des Rolladenpanzers sind die Profilleisten jeweils um das Maß der Lüftungsschlitze voneinander getrennt. In der Endphase der Schließbewegung erregt zunächst der Geber 14 den Sensor 10, vergleiche Fig. 2. Bei weiterem Herablassen des Rolladens werden auch die Lüftungsschlitze zwischen den Profilleisten 51 und 52 geschlossen, so daß der Geber 13 verzögert auf den Sensor 9 wirksam wird und den selben erregt. Diese aufeinanderfolgende Errregung der Sensoren 10 und 9 wird in der Auslösestufe 11 erfaßt und schaltet die Auslöseschaltung bereit.After installing the safety device in the manner described, it is always sensitive. When lowering the roller shutter curtain, the profile strips are each around the dimension of the ventilation slots separated from each other. In the final phase of the closing movement, the transmitter 14 is initially energized the sensor 10, see FIG. 2. When the roller shutter is lowered further, the ventilation slots become closed between the profile strips 51 and 52, so that the encoder 13 delays on the sensor 9 takes effect and excites the same. This sequential excitation of sensors 10 and 9 will in the trigger stage 11 detects and switches the trigger circuit ready.

    Bei ordnungsgemäßem Hochziehen des Rolladenpanzers werden die Profilleisten gelüftet, und zunächst wird der Geber 13 aus dem Schaltbereich des Sensors 9 wegbewegt, danach bewegt sich auch der Geber 14 entsprechend der weiteren Öffnung der Lüftungsschlitze aus dem Schaltbereich des Sensors 10. Bei Erkennung dieser Signalfolge in der Auslösestufe 11 bleibt die Alarmschaltung 12 unwirksam. Die Auslösestufe 11 wird wieder in den Ausschaltzustand versetzt. When the roller shutter curtain is raised properly, the profile strips are lifted and first, the transmitter 13 is moved away from the switching range of the sensor 9, then also moves the encoder 14 corresponding to the further opening of the ventilation slots from the switching range of the sensor 10. When this signal sequence is detected in the trigger stage 11, the alarm circuit 12 remains ineffective. The trigger stage 11 is switched back to the off state.

    Bei unbefugtem Hochschieben des Rolladenpanzers mit einem Einbruchwerkzeug oder dergleichen bleiben die Profilleisten auf Block und werden als Paket hochgezogen, so daß sich der Abstand der Geber 13 und 14 nicht ändert. Infolgedessen treten beide Geber 13, 14 gleichzeitig aus dem Schaltbereich der jeweiligen Sensoren 9, 10 aus und schalten dieselben um. Die gleichzeitigen Schaltsignale der Sensoren 9, 10 werden in der Auslösestufe 11 als Alarmzustand erkannt. Dieses führt zu einem Ausgangssignal, das die Alarmschaltung 12 erregt, so daß ein Alarm ausgelöst wird. Normalerweise ist dies ein akusatischer Alarm.If the roller shutter curtain is pushed up unauthorizedly with a burglary tool or the like the profile strips remain on block and are pulled up as a package, so that the distance between the Encoders 13 and 14 do not change. As a result, both transmitters 13, 14 leave the switching range at the same time of the respective sensors 9, 10 and switch them over. The simultaneous switching signals of the sensors 9, 10 are recognized in the trigger stage 11 as an alarm state. This leads to an output signal which excites the alarm circuit 12 so that an alarm is triggered. Usually this is a audible alarm.
