Abstract

A locking device for a roller shutter, whose slats (12, 14) are guided in lateral U-profile rails (16) and can be displaced in a limited manner relative to one another at the end of the unwinding movement, is obtained by articulating on at least one end of at least one slat blocking elements in the form of two levers (34) which can be folded apart like wings against spring force transversely with respect to the plane of the shutter, the ends of the levers in the folded- apart position engaging underneath stops (30) on the insides of the guide rail (16). The levers are folded apart by in each case one wedge (36) situated on the slat immediately above, which penetrates between the levers (34) when the slats are being moved one inside the other. Such lever pairs are advantageously arranged on either side of the shutter over the entire height thereof. <IMAGE>

Description

Die Erfindung betrifft eine Verriegelungseinrichtung für einen Rolladenpanzer, dessen Stäbe in seitlichen U-Profil­schienen geführt und am Ende der Abrollbewegung zwischen einer Lüftungsstellung und einer Schließstellung in senk­rechter Richtung begrenzt zueinander verschieblich sind, wobei an wenigstens einem Ende mindestens eines Rolladen­stabes ein Paar von Sperrelementen schwenkbar angelenkt ist, die bei der Einnahme der Schließstellung durch einen an einem höher gelegenen Rolladenstab angeordneten Keil quer zur Ebene des Panzers in eine das Hochheben desselben sperrende Eingriffsstellung mit der Führungsschiene ausein­anderspreizbar sind.The invention relates to a locking device for a roller shutter curtain, the rods of which are guided in lateral U-shaped rails and are limitedly displaceable to one another in the vertical direction at the end of the rolling movement between a ventilation position and a closed position, with a pair of locking elements being pivotably articulated on at least one end of at least one roller shutter rod which, when the closed position is taken, can be spread apart with the guide rail transversely to the plane of the tank by a wedge arranged on a higher-lying roller shutter bar in an engagement position blocking its lifting.

Eine derartige Verriegelungseinrichtung ist aus dem DE-GM 87 02 379 bekannt. Bei dieser bekannten Einrichtung beste­hen die Sperrelemente aus exzentrisch gelagerten Rollen, die an Lagerzapfen pendelnd aufgehängt sind und beim Ein­dringen des Keils in Reibungseingriff mit den Seitenwandun­gen der jeweiligen Führungsschiene gebracht werden. Die damit erzielte Verriegelung ist jedoch wegen des Reibschlus­ses unsicher und läßt sich bei geschickter Manipulation durch einen Einbrecher mühelos lösen.Such a locking device is known from DE-GM 87 02 379. In this known device, the locking elements consist of eccentrically mounted rollers which are suspended in a pivoting manner on bearing journals and are brought into frictional engagement with the side walls of the respective guide rail when the wedge penetrates. The locking achieved with this, however, is insecure due to the frictional engagement and can be easily solved by a burglar with skillful manipulation.

Eine andere bekannte Verriegelungseinrichtung (DE-OS 25 06 610), von welcher die zuvor beschriebene ausgeht, arbeitet mit einem von der Oberseite der Rolladenleiste aufragenden Lippenpaar mit einer dazwischen gelegenen Ver­tiefung zur Aufnahme des sich von der nächsthöheren Rolla­denleiste nach abwärts erstreckenden Keils, der beim Ver­riegeln die beiden Lippen gegen die Seitenwände der U-förmi­gen Rolladenführungsschiene festklemmt. Um die Klemmwir­kung zu verstärken ist in den beiden Lippen von oben ein Schlitz zur Aufnahme eines Krallenplättchens mit Spitzen eingelassen, die sich bei einer Aufwärtsbewegung der Rolla­denleiste im Material der Führungsschiene festfressen. Beim Hochziehen des Rolladens ist nicht gewährleistet, daß die­ses Festfressen beseitigt wird, so daß es erst besonderer mühsamer Maßnahmen bedarf, um den Rolladen zu lösen und völlig hochziehen zu können.Another known locking device (DE-OS 25 06 610), from which the one described above is based, works with a pair of lips protruding from the top of the roller shutter strip with an intermediate recess for receiving the wedge that extends downwards from the next higher roller shutter strip and which is used for Lock the two lips against the side walls of the U-shaped roller shutter guide rail. To increase the clamping effect, there is a slit in the two lips from above to accommodate a claw plate with tips embedded, which seize themselves in the material of the guide rail when the roller shutter strip moves upwards. When the roller shutter is pulled up, there is no guarantee that this seizure will be eliminated, so that only particularly laborious measures are required to release the roller shutter and to be able to pull it up completely.

Zwei weitere bekannte Verriegelungseinrichtungen (DE-AS 27 45 560 und DE-OS 33 23 663) arbeiten mit in den Stab­enden um quer zur Panzerebene gerichtete Achsen verschwenk­baren Hebeln, die vom nächsthöheren Rolladenstab gegen Fe­derkraft nach auswärts verschwenkbar sind und mit hakenför­migen Enden bzw. an den Enden angelenkten Sperrbolzen in Rasten am Grund der Führungsschiene eingreifen. Beide Kon­struktionen sind verhältnismäßig aufwendig und lassen sich nicht nachträglich einbauen bzw., wie es in der Praxis häu­fig vorkommt, bei einer Verkürzung der Rolladenbreite am Einbauort nachträglich anbringen.Two other known locking devices (DE-AS 27 45 560 and DE-OS 33 23 663) work with levers pivotable in the rod ends about axes directed transversely to the plane of the armor, which can be pivoted outwards against spring force by the next higher roller shutter rod and with hook-shaped ends or on engage the locking pins on the ends of the guide rails. Both constructions are relatively complex and cannot be retrofitted or, as is often the case in practice, can be retrofitted at the installation site if the width of the roller shutter is reduced.

Aufgabe der Erfindung ist es, eine einfache und dennoch betriebs- und einbruchssichere Verriegelungseinrichtung zu schaffen, die mit einfachen Mitteln jederzeit am Rolla­den angebracht werden kann.The object of the invention is to provide a simple, yet operational and burglar-proof locking device which can be attached to the roller shutter at any time with simple means.

Ausgehend von einer Verriegelungseinrichtung der eingangs genannten Art löst die Erfindung diese Aufgabe dadurch, daß die Sperrelemente von unter der Wirkung des Keils flü­gelartig gegen Federkraft auseinanderklappbaren Hebeln ge­bildet sind, deren Enden in der auseinandergeklappten Stel­lung Anschläge an den Innenseiten der Führungsschiene unter­greifen.Starting from a locking device of the type mentioned, the invention solves this problem in that the locking elements are formed by wing-like levers which can be unfolded under the action of the wedge against spring force, the ends of which in the unfolded position engage under stops on the inner sides of the guide rail.

Der in den Figuren 1 bis 3 gezeigte Rolladenpanzer 10 be­steht - zumindest im unteren Teil, der allein dargestellt ist - im Wechsel aus Kastenprofilstäben 12 und C-Profil­stäben 14, die gelenkig ineinandergreifen und zugleich eine begrenzte Verschiebung zueinander in senkrechter Richtung gestatten. Der Rolladenpanzer 10 ist bei geöffnetem Rolla­den in bekannter Weise auf einer (nicht gezeigten) Panzer­welle innerhalb eines oberhalb der zu verschließenden Ge­bäudeöffnung angebrachten Rolladenkastens aufgewickelt und wird beim Schließen des Rolladens von der Panzerwelle abge­wickelt und dabei beiderseits in Führungsschienen 16 ge­führt, die an den Seiten der Gebäudeöffnung bis zur Öff­nungsunterkante 18, d. h. einem Fensterbrett oder einer Tür­schwelle, reichen. Das untere Ende des Panzers wird von einem hohlen Endstab 20 gebildet, der mit einem Haken 22 gelenkig den anschließenden Kastenprofilstab 12 erfaßt.The roller shutter curtain 10 shown in Figures 1 to 3 consists - at least in the lower part, which is shown alone - in alternation of box section bars 12 and C section bars 14 which interlock and at the same time allow a limited displacement to each other in the vertical direction. The roller shutter curtain 10 is wound in a known manner on an armored shaft (not shown) inside a roller shutter box attached above the building opening to be closed when the roller shutter is open and is unwound from the armored shaft when the roller shutter is closed and is guided on both sides in guide rails 16 which are on the sides of the Building opening up to the bottom edge 18, d. H. a window sill or a threshold. The lower end of the armor is formed by a hollow end rod 20 which articulates the adjoining box section rod 12 with a hook 22.

Beim Herablassen des Rolladens nehmen die Profilstäbe 12, 14 die in den Figuren 1 und 2 gezeigte auseinandergezogene Stellung ein, bis der Endstab 20 von der Unterkante 18 der Gebäudeöffnung abgefangen wird. Nicht gezeigte Lüftungs­schlitze in den C-Profilstäben 14 oder auch den Kastenpro­filstäben 12 gestatten solange einen Luftaustausch zwischen dem Innenraum und der äußeren Atmosphäre bei geöffnetem Fenster bzw. geöffneter Tür, weshalb diese Stellung auch als "Lüftungsstellung" bezeichnet werden kann. Wird nach dem Aufsitzen des Endstabes 20 auf der Unterkante 18 der Gebäudeöffnung der Rolladenpanzer weiter abgesenkt, schie­ben sich, am unteren Ende beginnend, die Rolladenstäbe 12, 14 ineinander und verschließen die Lüftungsöffnungen, bis schließlich alle Lüftungsöffnungen geschlossen sind und damit die "Schließstellung" des Rolladenpanzers erreicht ist.When the roller shutter is lowered, the profiled bars 12, 14 assume the expanded position shown in FIGS. 1 and 2 until the end bar 20 is intercepted by the lower edge 18 of the building opening. Ventilation slots, not shown, in the C-profile bars 14 or also the box-profile bars 12 allow an air exchange between the interior and the outside atmosphere with the window or door open, which is why this position can also be referred to as the "ventilation position". After the end bar 20 is seated on the lower edge 18 of the building opening, the roller shutter curtain is lowered further, starting at the lower end, the roller shutter bars 12, 14 slide into one another and close the ventilation openings until finally all ventilation openings are closed and thus the "closed position" of the Roller shutter curtain is reached.

Die Führungsschienen 16 enthalten an den Maulöffnungen ge­geneinander weisende V-Profildichtungen 22, welche gegen die Kastenprofilstäbe 12 abdichten und zugleich den Rolla­denpanzer 10 in der Maulöffnung der Führungsschiene zentrie­ren.The guide rails 16 contain mutually facing V-profile seals 22 at the jaw openings, which seal against the box profile bars 12 and at the same time center the roller shutter curtain 10 in the jaw opening of the guide rail.

In die Führungsschienen 16 sind ferner Anschlagelemente 24 eingesetzt und mit Schrauben 26 am Zwischenboden 28 der Führungsschienen 16 verschraubt. Jede Führungsschiene 16 enthält mindestens ein Anschlagelement 24 unmittelbar ober­halb der Öffnungsunterkante 18, und weitere Anschlagelemen­te 24 können in bestimmten Abständen nach oben anschließen. Die Anschlagelemente 24 haben, wie aus Fig. 3 ersichtlich, U-förmigen Querschnitt mit gegeneinander abgewinkelten Schenkelenden 25 und tragen an den oberen Enden ihrer Schen­kelwände gegeneinander gerichtete Anschlagschultern 30, die mit Verriegelungseinheiten 32 am Rolladenpanzer 10 zusammen­wirken, wenn dieser aus der Lüftungsstellung in die Schließ­stellung abgesenkt wird.Stop elements 24 are also inserted into the guide rails 16 and screwed to the intermediate floor 28 of the guide rails 16 with screws 26. Each guide rail 16 contains at least one stop element 24 immediately above the lower opening edge 18, and further stop elements 24 can connect upwards at certain intervals. The stop elements 24, as can be seen in FIG. 3, have a U-shaped cross-section with angled leg ends 25 and carry, at the upper ends of their leg walls, opposing abutment shoulders 30, which cooperate with locking units 32 on the roller shutter curtain 10 when it moves from the ventilation position into the Closed position is lowered.

Jede Verriegelungseinheit 32 besteht in der Hauptsache aus einem Paar von Sperrgliedern in Gestalt zweier flügelartig auseinanderklappbarer Hebel 34 am Stirnende eines Kastenpro­filstabes 12 und einem Keil 36 am Stirnende des nächsthöhe­ ren Kastenprofilstabes 12 (Fig. 4 und 7), der beim Verschie­ben der Stäbe in die Schließstellung (Fig. 9 und 10) zwi­schen die Hebel 34 eindringt und diese derart auseinander­klappt, daß die oberen Enden der Hebel 34 die Anschlagschul­tern 30 der Anschlagelemente 24 untergreifen.Each locking unit 32 consists mainly of a pair of locking members in the form of two wing-like foldable lever 34 at the front end of a box section bar 12 and a wedge 36 at the front end of the next height Ren box section rod 12 (FIGS. 4 and 7), which penetrates between the levers 34 when the rods are moved into the closed position (FIGS. 9 and 10) and unfolds them such that the upper ends of the levers 34 engage under the stop shoulders 30 of the stop elements 24 .

Die Hebel 34 weisen an den unteren Enden Lageraugen 38 auf, die, in Achsrichtung betrachtet, jeweils zur Hälfte wegge­schnitten sind und dadurch eine scharnierartige Lagerung auf einem Kopfbolzen 40 gestatten, der in die Bohrung 42 eines Aufnahmeteils 44 eingesetzt und darin durch einen Sicherungsstift 46 gehalten ist. Das Aufnahmeteil 44, das zweckmäßig aus Aluminiumdruckguß besteht, ist in seinem Querschnitt der unteren Kammer des Kastenprofilstabs 12 angepaßt und in diese bis zum Anschlag eines plattenförmi­gen Ansatzes 48 gegen das Stirnende der oberen Kammer des Kastenprofilstabs 12 eingeschoben und auf geeignete Weise gesichert. Ein zapfenförmiger Ansatz 50 des Aufnahmeteils 44 erstreckt sich parallel zum Kopfbolzen 40 und greift zwischen die mit halbkreisförmigen Aussparungen 52 versehe­nen Hebel 44 ein, die an den Außenseiten von einer Schen­kelfeder 54 erfaßt und von dieser in der Ruhestellung gegen den zapfenförmigen Ansatz 50 in einer definierten Mittel­lage gehalten werden.The levers 34 have bearing eyes 38 at the lower ends, which, when viewed in the axial direction, are each cut in half and thereby allow a hinge-like mounting on a headed pin 40, which is inserted into the bore 42 of a receiving part 44 and held therein by a locking pin 46 is. The receiving part 44, which suitably consists of die-cast aluminum, is adapted in its cross-section to the lower chamber of the box section bar 12 and inserted into it until a plate-shaped projection 48 stops against the front end of the upper chamber of the box section bar 12 and secured in a suitable manner. A pin-shaped projection 50 of the receiving part 44 extends parallel to the headed pin 40 and engages between the lever 44 provided with semicircular recesses 52, which is gripped on the outer sides by a leg spring 54 and by this in the rest position against the pin-shaped projection 50 in a defined central position being held.

Der Keil 36 ist an einem Abschlußteil 56 angeformt, das in den vorzugsweise länger ausgebildeten nächsthöheren Kasten­profilstab 12 eingesetzt und darin auf geeignete Weise ge­sichert ist. Das Abschlußteil 56 besitzt hierzu zweckmäßig einen den Kammern des Kastenprofils angepaßten Querschnitt und schließt mit seiner Endwand die Kammern des Kastenpro­filträgers nach außen ab. Ähnliche Abschlußteile 58, die je­doch ohne Keil ausgeführt sind, können die darüber befind­lichen Kastenprofilstäbe 12 abschließen, sofern diese nicht wiederum mit Verriegelungseinheiten 32 bzw. Keilen 36 ver­sehen sind.The wedge 36 is integrally formed on a closing part 56, which is inserted into the next higher box section bar 12, which is preferably longer, and is suitably secured therein. For this purpose, the end part 56 suitably has a cross section adapted to the chambers of the box section and closes with its end wall the chambers of the box section carrier from the outside. Similar end parts 58, which, however, are designed without a wedge, can close off the box section bars 12 located above, provided that these are not in turn provided with locking units 32 or wedges 36.

Wie aus den Figuren 2, 4 und 6 ersichtlich ist, folgen, von unten nach oben betrachtet, auf den Endstab 20 ein Ka­stenprofilstab 12 mit einer Verriegelungseinheit 32, ein Kastenprofilstab 12 mit einem Keil 36 sowie zwei Kastenpro­filstäben mit gewöhnlichen Abschlußteilen 58, und diese Reihenfolge wiederholt sich beliebig oft nach oben, wobei es zweckmäßig ist, sie über die gesamte Höhe der Gebäude­öffnung fortzusetzen, um dem Einbrecher keine Möglichkeit zu geben, den Rolladen, an den oberen Stäben beginnend, aufzudrücken.As can be seen from FIGS. 2, 4 and 6, viewed from the bottom upwards, the end bar 20 is followed by a box section bar 12 with a locking unit 32, a box section bar 12 with a wedge 36 and two box section bars with conventional end parts 58, and this sequence repeats itself upwards as often as desired, whereby it is advisable to continue it over the entire height of the building opening in order not to give the burglar any opportunity to open the roller shutters, starting at the upper bars.

Die Anordnung von Verriegelungseinheiten an beiden Längskan­ten des Panzers über dessen gesamte Höhe hat darüber hinaus in Verbindung mit den oben erwähnten, einwärts abgewinkel­ten Schenkelenden 25 der Anschlagelemente 24 noch einen weiteren Vorteil: mit Hilfe der Schenkelenden 25 wird näm­lich der Panzer über seine gesamte Höhe bei auseinanderge­klappten Hebeln 34 gegen ein Herausziehen aus den Führungs­schienen 16 gesichert, so daß zum einen ein Herausheben des Panzers durch ein Durchbiegen der Rolladenstäbe quer zur Panzerebene nicht möglich ist und zum anderen bei entspre­chender Tolerierung in gleicher Richtung wirkende Windkräf­te am Panzer besser abgefangen werden.The arrangement of locking units on both longitudinal edges of the tank over its entire height also has another advantage in connection with the above-mentioned, inwardly angled leg ends 25 of the stop elements 24: namely, with the help of the leg ends 25, the tank is unfolded over its entire height Levers 34 secured against pulling out of the guide rails 16, so that on the one hand it is not possible to lift the armor out by bending the roller shutter bars transversely to the armor level and, on the other hand, wind forces acting on the armor are better intercepted with appropriate tolerance in the same direction.

Mit der Reihenfolge der einzelnen Elemente an den Kasten­profilstäben und der Querschnittshöhe dieser Stäbe ist der Abstand der Anschlagelemente innerhalb der Führungsschienen vorgegeben. Die Anschlagelemente können von vorn herein in den Führungsschienen befestigt sein. Sie können aber auch nachträglich am Bau angebracht werden, insbesondere dann, wenn die Führungsschienen erst bei der Montage des Rolladens abgelängt werden.The spacing of the stop elements within the guide rails is predetermined with the order of the individual elements on the box section bars and the cross-sectional height of these bars. The stop elements can be fastened in the guide rails from the beginning. But they can also be retrofitted to the building, especially if the guide rails are cut to length only when the roller shutter is being installed.

Es versteht sich von selbst, daß die Verriegelungseinheiten 32 an beiden Seitenkanten des Rolladenpanzers vorhanden sein sollten, wobei sie zweckmäßig stets paarweise an ein und demselben Rolladenstab angebracht sind.It goes without saying that the locking units 32 should be present on both side edges of the roller shutter curtain, whereby they are expediently always attached in pairs to one and the same roller shutter slat.

Die Erfindung ist nicht auf die Anwendung der Verriegelungs­einrichtung bei Kastenprofilstäben mit dazwischen angeord­neten C-Profilstäben beschränkt, sondern läßt sich bei prak­tisch allen Rolladenprofilen anwenden. Auch können die He­bel 34 im hochgeklappten Zustand eine größere Gesamtbreite als die Stabprofile aufweisen, sofern nur, wie im Beispiels­fall durch die V-Profildichtungen 22, sichergestellt ist, daß die Enden der Rolladenstäbe mit den zusammengeklappten Hebeln innerhalb der Maulöffnung einer jeden Führungsschie­ne zentriert sind.The invention is not limited to the use of the locking device in box profile bars with C-profile bars arranged in between, but can be applied to practically all roller shutter profiles. The levers 34 can also have a greater overall width than the bar profiles when they are folded up, provided that, as in the example by the V-profile seals 22, it is ensured that the ends of the roller shutter bars with the folded levers are centered within the jaw opening of each guide rail.
