Description

Die Erfindung betrifft eine selbsttätige Rolladensicherung gegen Hochschieben des Rolladenpanzers aus Profilstäben, die in U-förmigen Schienen geführt und in Bewegungsrichtung des Rolladenpanzers be­grenzt gegeneinander verschiebbar sind, mit mindestens einem Sperr­glied, dessen oberes scharfkantiges Ende an einen Schenkel der Füh­rungsschiene andrückbar ist und das einerseits über ein erstes la­schenförmiges Koppelglied zur Übertragung der Andrückkraft mit einer unteren, an einem unteren Profilstab befestigten Halterung und über ein zweites Koppelglied mit einer oberen, an einem oberen Profilstab befestigten Halterung verbunden ist, wobei das Sperrglied und die Kop­pelglieder senkrecht zur Ebene des Rolladenpanzers bewegbar sind.The invention relates to an automatic roller shutter protection against pushing up the roller shutter curtain from profiled bars which are guided in U-shaped rails and are limitedly displaceable against each other in the direction of movement of the roller shutter curtain, with at least one locking member, the upper sharp end of which can be pressed against one leg of the guide rail and on the one hand via a first link-shaped coupling member for transmitting the pressing force is connected to a lower bracket fastened to a lower profile bar and via a second coupling member to an upper bracket fastened to an upper section bar, the locking member and the coupling links being movable perpendicular to the plane of the roller shutter curtain.

Bei einer Rolladensicherung dieser Art muß das Unterende des Sperrgliedes jeweils gesondert abgestützt werden. Hierzu sind zusätz­liche Bauteile erforderlich, die insbesondere eine genaue Einpassung benötigen, um eine sichere Funktion zu gewährlsieten.With a roller shutter lock of this type, the lower end of the locking member must be supported separately. For this purpose, additional components are required, which in particular require an exact fit in order to ensure reliable functioning.

Aufgabe der Erfindung ist die Bereitstellung einer Rolladensiche­rung, bei der das Sperrglied unmittelbar innerhalb der Führungsschie­ne verklemmt und verkeilt werden kann, ohne daß eine Gelenkverbindung innerhalb dieses Klemmweges angeordnet ist.The object of the invention is to provide a roller shutter safety device in which the locking member can be clamped and wedged directly within the guide rail without an articulated connection being arranged within this clamping path.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß auch das untere Ende des Sperrgliedes kantig ausgebildet ist und durch die jeweilige Koppellasche an den gegenüberliegenden Schenkel der U-Schie­ne andrückbar ist.This object is achieved according to the invention in that the lower end of the locking member is angular and can be pressed by the respective coupling tab on the opposite leg of the U-rail.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als das Sperrglied wie ein Knebel mit beiden Enden an entgegengesetz­te Schenkel der U-Schiene angedrückt sird. Das Sperrglied wird als Knebel in die U-Schiene eingedrückt und darin verkeilt. Damit kann die gesamte Spannkraft innerhalb des Sperrgliedes aufgenommen werden. Das Sperrglied ist in seiner Länge unveränderlich festgelegt. Es erge­ben sich keine Schwankungen oder Veränderungen durch eine Gelenkver­bindung. Die Koppellaschen übertragen die Druckkräfte, die bei unbe­fugter Manipulation an dem Rolladenpanzer auftreten, und bewirken ein Verspannen und Verkeilen des knebelartigen Sperrgliedes.The invention differs from the prior art in that the locking member is pressed like a gag with both ends on opposite legs of the U-rail. The locking element is pressed into the U-rail as a gag and wedged in it. So that can the entire clamping force can be absorbed within the locking member. The length of the locking member is fixed. There are no fluctuations or changes due to a joint connection. The coupling straps transmit the compressive forces that occur on the roller shutter curtain in the event of unauthorized manipulation and cause the gag-like locking element to be braced and wedged.

Eine erhöhte Sperrwirkung erzielt man dadurch, daß zwei Sperr­glieder kreuzförmig zueinander angeordnet sind. Hierdurch wird vor allem eine symmetrische Verspannung sichergestellt.An increased locking effect is achieved in that two locking members are arranged in a cross shape to each other. This ensures a symmetrical bracing.

Eine erhöhte Sicherungwirkung erzielt man dadurch, daß mehrere kreuzförmig angeordnete Paare von Sperrgliedern übereinander vorgese­hen sind.An increased securing effect is achieved in that several pairs of locking members arranged in a cross shape are provided one above the other.

Eine zwangsweise Führung der Sperrglieder wird dadurch sicherge­stellt, daß die Sperrglieder in der Mitte durch einen Gelenkzapfen miteinander verbunden sind.A forced guidance of the locking members is ensured in that the locking members are connected to one another in the middle by a pivot pin.

Eine sichere Verkeilung innerhalb eines großen Breitenbereichs der U-Schine wird dadurch erreicht, daß am Oberende jedes Sperrglie­des ein oder mehrere Sperrzähne angeformt sind.Secure wedging within a large width range of the U-rail is achieved in that one or more locking teeth are formed on the upper end of each locking element.

Die Zentrierung innerhalb der U-Schine wird dadurch gesichert, daß die Sperrglieder durch je eine Koppellasche mit der unteren Halte­rung bzw. Halterungslasche gekoppelt sind.The centering within the U-rail is ensured in that the locking members are each coupled to the lower bracket or bracket bracket by a coupling bracket.

Eine zwangsweise Führung der Sperrglieder wird dadurch gewährlei­stet, daß die beiden Koppellaschen in einer gemeinsamen Gelenkachse mit der unteren Halterung bzw. Halterungslasche verbunden sind.A forced guidance of the locking members is ensured in that the two coupling straps are connected to the lower bracket or mounting bracket in a common hinge axis.

Die Anlage der Sperrglieder wird dadurch gefördert, daß an der unteren Halterung bzw. Halterungslasche eine Spreizfeder vorgesehen ist, die in die Koppellaschen eingehängt ist.The installation of the locking members is promoted in that a spreading spring is provided on the lower bracket or bracket tab, which is suspended in the coupling tabs.

Eine selbsttä#tige Anpassung und Zentrierung innerhalb der U-Schiene wird dadurch erreicht, daß die oberen Koppelglieder über ein Zugband und/oder eine Lasche mit dem Gelenk gekoppelt sind.Automatic adjustment and centering within the U-rail is achieved in that the upper coupling links are coupled to the joint via a tension band and / or a strap.

Die geordnete Betätigung des Sperrglieder wird dadurch verbes­sert, daß die Sperrglieder an Koppellaschen angelenkt sind, die über eine gemeinsame Gelenkverbindung und das Zugband mit der oberen Halte­rung verbunden sind.The orderly actuation of the locking members is improved in that the locking members are articulated on coupling lugs which are connected to the upper bracket via a joint joint and the tension band.

In manchen Fällen läßt sich der Eingriff dadurch verbessern, daß die oberen Koppelglieder über ein oder mehrere Halterungslaschen mit dem Gelenk verbunden sind.In some cases, the engagement can be improved by connecting the upper coupling links to the joint via one or more mounting brackets.

Eine feste Verbindung mit der Rolladenpanzer wird dadurch er­zielt, daß die obere Halterung zwei parallel zueinander ausgerichtete Schenkel aufweist, zwischen denen eine Wand eines Profilstabes Aufnah­me findet.A firm connection with the roller shutter curtain is achieved in that the upper bracket is aligned two parallel to each other Has legs between which a wall of a profile bar is accommodated.

Die untere Halterung, die in der Höhe anpaßbar sein muß, erhält dadurch eine feste Verbindung mit dem jeweiligen Profilstab, daß die untere Halterung an ihrem Schenkel Krallen aufweist.The lower bracket, which must be adjustable in height, receives a firm connection with the respective profile rod in that the lower bracket has claws on its leg.

Eine Ausführungsform der Erfindung wird im Folgenden unter Bezug­nahme auf die anliegende Zeichnung erläutert, in der darstellen:

  • Fig. 1 eine an einem Rolladenpanzer angeordnete Rolladensiche­rung in gelüftetem Zustand der Profilstäbe,
  • Fig. 2 eine Seitenansicht zu Fig. 1 und
  • Fig. 3 eine der Fig. 1 entsprechende Darstellung der Sperrstel­lung.
An embodiment of the invention is explained below with reference to the accompanying drawing, in which:
  • 1 is a shutter protection arranged on a roller shutter curtain in the released state of the profile bars,
  • Fig. 2 is a side view of Fig. 1 and
  • Fig. 3 is a representation of the locking position corresponding to FIG. 1.

Die Figuren zeigen eine U-Schiene 1 mit zwei Schenkeln 2 und 3. In Umrissen sind drei Profilstäbe 4 dargestellt, die mit Hakenprofi­len oder Profilstegen ineinander gehängt sind. Es ist eine gegenseiti­ge Verschiebung der Profilstäbe beim Hochziehen des Rolladens mög­lich, vergleiche Fig. 1. In herabgelassenem Zustand des Rolladens sit­zen die Profilstäbe nach Fig. 3 im wesentlichen unmittelbar nacheinan­der auf. Dadurch ergibt sich, daß der gegenseitige vertikale Abstand der Profilstäbe 4 in geschlossenem Zustand des Rolladens kleiner ist. An einem unteren Profilstab ist eine Halterung 6 befestigt, die mit einem Schenkel 7 an dem unteren Profilstab 4 verschraubt, vernietet oder in andererweise festgelegt ist. An dem Schenkel sind Krallen 25 abgewinkelt, die in die Wandung des Profilstabes eindringen und so eine feste Verbindung gerantieren. Der Schenkel 7 läßt sich in der Höhe an die jeweiligen Einbauverhältnisse anpassen. Zu der Halterung 6 gehört eine gelenkig angesetzte Halterungslasche 8, an deren Oberen­de auf einem Zapfen 9 zwei Koppellaschen 10 angelenkt sind. Die Halte­rungslasche 8 ermöglicht eine selbsttätige Einstellung und Zentrie­rung innerhalb der U-Schiene 1 unabhängig von dem Profilstäben des Rolladenpanzers.The figures show a U-rail 1 with two legs 2 and 3. In outline, three profile bars 4 are shown, which are hung one inside the other with hook profiles or profile webs. A mutual displacement of the profiled bars is possible when the roller shutter is pulled up, compare FIG. 1. When the shutters are lowered, the profiled bars according to FIG. 3 essentially sit one after the other. This means that the mutual vertical spacing of the profile bars 4 is smaller in the closed state of the roller shutter. A bracket 6 is fastened to a lower profile bar, which is screwed, riveted or otherwise fixed to the lower profile bar 4 with a leg 7. On the leg claws 25 are angled, which penetrate into the wall of the profile bar and thus ensure a firm connection. The leg 7 can be adjusted in height to the respective installation conditions. The bracket 6 includes an articulated mounting bracket 8, at the upper end of which 9 coupling links 10 are articulated on a pin 9. The bracket tab 8 allows automatic adjustment and centering within the U-rail 1 regardless of the profile bars of the roller shutter curtain.

Jede Koppellasche 10 ist über einen Gelenkzapfen mit einem Sperr­glied 11 verbunden. Die beiden Sperrglieder sind am unteren Ende 13 kantig ausgebildet. Am oberen Ende sind ein oder mehrere Sperrzähne 14 vorgesehen. Die beiden Sperrglieder 11 sind kreuzweise über einen Gelenkzapfen 15 miteinander gekoppelt. Wahlweise spannt eine Spreizfe­der 21 die Koppellaschen 10 in Sperrlage vor. Man kann mehrere Paare von Sperrgliedern aneinander koppeln. Am oberen Ende jedes Sperrglie­des 11 greift gelenkig eine Koppellasche 16 an. Die beiden Koppella­ schen 16 sind über ein Gelenk 17 mit einem Zugband 18 verbunden. Man kann auch eine Lasche 24, die in Fig. 2 in strichpunktierten Linien eingezeichnet ist, zwischen dem Gelenk 17 und dem Zugband 18 anord­nen. Das Zugband 18 kann ein Band, ein Draht, eine Kette, ein Laschen­gekenkzug oder ein anderes Zugelement sein, das eine Zugkraft übertra­gen kann. Das Zugband 18 ist an einer oberen Halterung 19 befestigt, deren Schenkel 20a und 20b mit einem oberen Profilstab 4 verbunden sind. Die Schenkel 20a und 20b schließen die Wand des jeweiligen Pro­filstabes zwischen sich ein. Da die Befestigungselemente wie Schrau­ben oder Nieten in den Schenekeln halten, ist so eine dauerhafte und ausreißfeste Verbindung gewährleistet.Each coupling plate 10 is connected to a locking member 11 via a hinge pin. The two locking members are angular at the lower end 13. One or more locking teeth 14 are provided at the upper end. The two locking members 11 are crosswise coupled to one another via a hinge pin 15. Optionally, a spreading spring 21 biases the coupling plates 10 in the locked position. You can couple several pairs of locking elements together. At the upper end of each locking member 11, a coupling tab 16 is articulated. The two Koppella 16's are connected to a drawstring 18 via a joint 17. It is also possible to arrange a tab 24, which is drawn in dash-dotted lines in FIG. 2, between the joint 17 and the tension band 18. The tension band 18 can be a band, a wire, a chain, a link link pull or other tension element that can transmit a tensile force. The tension band 18 is fastened to an upper bracket 19, the legs 20a and 20b of which are connected to an upper profile bar 4. The legs 20a and 20b enclose the wall of the respective profile bar between them. Since the fastening elements such as screws or rivets hold in the thighs, a permanent and tear-resistant connection is guaranteed.

Anstelle des Zugbandes 18 kann man auch zwei Laschen 22 und 23 vorsehen, die in Fig. 2 in strichpunktierten Linien eingezeichnet sind. Diese Laschen können auch eine Druckkraft übertragen und gewähr­leisten so eine unmittelbare Anlage der Rolladensicherung.Instead of the drawstring 18, two tabs 22 and 23 can also be provided, which are shown in dash-dotted lines in FIG. 2. These tabs can also transmit a compressive force and thus ensure that the roller shutter safety device is in direct contact.

Die Rolladensicherung nach der Erfindung befindet sich innerhalb der U-Schiene 1 und liegt an dem Mittelsteg derselben an, wie dies insbesondere aus Fig. 2 ersichtlich ist. Da alle Teile der Rolladensi­cherung plattenförmig ausgebildet sind, hat die Rolladensicherung in Längsrichtung der Profilstäbe nur eine geringe Ausdehnung, so daß sie ohne Schwierigkeiten innerhalb der U-Schiene verdeckt Aufnahme findet.The roller shutter lock according to the invention is located within the U-rail 1 and lies against the central web thereof, as can be seen in particular from FIG. 2. Since all parts of the roller shutter safety device are plate-shaped, the roller shutter safety device has only a small extension in the longitudinal direction of the profile bars, so that it can be accommodated concealed within the U-rail without difficulty.

Fig. 1 zeigt den Rolladenpanzer in auseinandergezogenem Zustand innerhalb der Profilschiene. Dabei ist auch die Rolladensicherung aus­einandergezogen, weil die Halterungen 6 und 19 entsprechend an den Profilstäben angeordnet sind, so daß die einzelnen Glieder der Rolla­densicherung langgestreckt aneinander anschließen. Die Bewegung des Rolladenpanzers beim Heben oder Senken desselben wird in diesem Zu­stand durch die Rolladensicherung nicht behindert.Fig. 1 shows the roller shutter curtain in the pulled-apart state within the profile rail. The roller shutter lock is pulled apart because the brackets 6 and 19 are arranged accordingly on the profile bars, so that the individual members of the roller shutter lock elongate to each other. The movement of the roller shutter armor when lifting or lowering the same is not hindered by the roller shutter safety device in this state.

In herabgelassenem Zustand des Rolladenpanzers nach Fig. 3 sit­zen die Profilstäbe 4 bündig aufeinander auf, so daß der Abstand zwi­schen den Laschen 6 und 19 kleiner wird. Dadurch wird jedes Sperr­glied 11 knebelartig geschränkt. Die durch den Zapfen 9 festgelegte Gelenkachse und die Achse des Gelenks 17 zentrieren sich selbsttätig so innerhalb der U-Schiene, daß die Sperrglieder 11 mit beiden Enden gleichmäßig an den Schenkeln 2, 3 der U-Schine 1 anliegen. Die Gelenk­verbindungen begünstigen eine gleichmäige Aufspreizung beider Sperr­glieder 11. Diese Zentrierung wird durch die Halterungslasche 8 und das Zugband 18 begünstigt, da diese Elenente eine Bewegung in Quer­ richtung der U-Schiene 1 zulassen.In the lowered state of the roller shutter curtain according to Fig. 3, the profile bars 4 sit flush on each other, so that the distance between the tabs 6 and 19 is smaller. As a result, each locking member 11 is gagged. The joint axis defined by the pin 9 and the axis of the joint 17 center themselves within the U-rail in such a way that the locking members 11 bear evenly on the legs 2, 3 of the U-rail 1 with both ends. The articulated connections favor a uniform spreading of the two locking members 11. This centering is favored by the mounting bracket 8 and the tension band 18, since this element moves in a transverse direction Allow direction of U-rail 1.

Bei einem unbefugten Hochschieben der Profilstäbe 4 von unten wird durch die Koppellaschen 10 eine Druckkraft auf die Sperrglieder 11 übertragen. Das obere Ende jedes Sperrgliedes 11 verkrallt sich mit mindestens einem Sperrzahn 14 an den Schenkel 3 der U-Schiene 1. Das untere Ende 13 wird an den gegenüberliegenden Schenkel 2 ange­drückt. Somit wird das Sperrglied 11 knebelartig innerhalb der U-Schiene verkeilt. Die Klemmkraft wird durch das Sperrglied 11 selbst auf beide Schenkel der U-Schiene übertragen. Da das Sperrglied 11 laschenförmig ausgebildet ist, kann so eine hohe Klemmkraft er­zielt wird.In the event of an unauthorized pushing up of the profile bars 4 from below, a pressure force is transmitted to the locking members 11 through the coupling tabs 10. The upper end of each locking member 11 engages with at least one locking tooth 14 on the leg 3 of the U-rail 1. The lower end 13 is pressed against the opposite leg 2. Thus, the locking member 11 is wedged like a gag within the U-rail. The clamping force is transmitted by the locking member 11 itself to both legs of the U-rail. Since the locking member 11 is tab-shaped, a high clamping force can be achieved.

Durch die kreuzweise Anordnung von zwei Sperrgliedern 11 sichert man eine zwangsläufige Bewegung und Verkeilung der Sperrzähne 14 beim Hochdrücken der unteren Profilstäbe 4. Mehrere Sperrzähne stellen in U-Schinen unterschiedlicher Breite eine feste Verklemmung sicher.The crosswise arrangement of two locking members 11 ensures an inevitable movement and wedging of the locking teeth 14 when the lower profile bars 4 are pushed up. A plurality of locking teeth ensure firm jamming in U-rails of different widths.

Anstelle des Zugbandes 18 kann man auch mehrere Laschen 22, 23, zur Kopplung mit der oberen Halterung vorsehen, wie dies in Fig. 3 in strichpunktierten Linien eingezeichnet ist.Instead of the drawstring 18, it is also possible to provide a plurality of tabs 22, 23 for coupling to the upper holder, as shown in broken lines in FIG. 3.
