Abstract
Description
Die Erfindung betrifft eine Verriegelungsvorrichtung für ein in einer Ebene verschiebbares Verschlussorgan einer Gebäudeöffnung, insbesondere einen Rollladen, mit einem Schwenkhebel, bei dessen Betätigung mindestens ein Riegelelement von einer Freigabestellung im wesentlichen quer zur Bewegungsrichtung des Verschlussorgans in eine Sperrstellung bringbar ist, in der es mit einem an der Gebäudeöffnung angeordneten Sperrteil im Eingriff zu stehen bestimmt ist.The invention relates to a locking device for in a Plane of a building opening which can be displaced, in particular a roller shutter, with a swivel lever, at least when actuated a locking element from a release position substantially transverse to the direction of movement the closure member can be brought into a locked position in which it to be in engagement with a blocking part arranged at the building opening is determined.
Um zu verhindern, dass geschlossene Rollläden zwecks Einbruchs von aussen her nach oben geschoben werden, sind verschiedene Massnahmen bekannt. Eine dieser Massnahmen besteht aus Riegeln, die am unteren Ende des Rollladens angebracht sind und bei geschlossenem Rollladen derart verschoben werden, dass sie beispielsweise in Öffnungen greifen, die in der seitlichen Rollladenführung oder in der Leibung vorgesehen sind. Bei einer bekannten Verriegelungsvorrichtung ist jeder Riegel mit einer Rändelschraube versehen, die dazu dient, den Riegel mit der Hand zu verschieben und ihn in seiner Position zu arretieren. Eine andere bekannten Lösung, bei der die Riegel mit einer Zahnstange ausgerüstet sind, hat den Vorteil, dass durch Drehen eines zentral angeordneten Zahnrades zwei Riegel gleichzeitig verschoben werden können.To prevent closed shutters from being burglarized Different measures are pushed upwards from the outside known. One of these measures consists of bars that are at the bottom of the roller shutter are attached and moved in this way when the roller shutter is closed that they reach into openings, for example, in the side Roller shutter guidance or in the reveal are provided. With a known Locking device, each bolt is provided with a knurled screw, which is used to move the latch by hand and hold it in its Lock position. Another known solution, in which the latch with a rack has the advantage that by turning one centrally located gear two bolts are moved simultaneously can.
Der Hauptnachteil dieser bekannten Vorrichtungen besteht insbesondere darin, dass die Riegel jedesmal nach dem Schliessen des Rollladens manuell betätigt werden müssen, wobei dazu das betreffende Fenster oder die Türe geöffnet werden muss. Es liegt auf der Hand, dass bei derartigen Vorrichtungen das Verriegeln des geschlossenen Rollladens leicht vergessen wird.The main disadvantage of these known devices is in particular in that the latches each time the shutter is closed must be operated manually, for this purpose the window or Doors must be opened. It is obvious that such devices locking the closed roller shutter is easily forgotten.
Es sind auch Vorrichtungen bekannt, die den Rollladen automatisch verriegeln, wenn dieser seine Schliessstellung erreicht. So zeigt zum Beispiel die EP-A1-0 043 021 eine selbsttätige Sicherung eines Rollladens, bei welcher die Rollladenwalze bei geschlossenem Rollladen blockiert wird. Bei vielen Rollläden sind heutzutage die Lamellen so miteinander verbunden, dass sie um einen Betrag auseinander gezogen werden können, um zwischen sich einen Spalt zum Durchlassen von Luft und Licht zu bilden. Ein solcher Rollladen ist mit einer Vorrichtung dieses Typs nur dann ausreichend gesichert, wenn er so weit geschlossen ist, dass alle Lamellen aneinander anliegen. Andernfalls könnte ein Einbrecher das untere Ende des Rollladens so weit nach oben schieben, bis alle Spalte zwischen den Lamellen geschlossen wären, ohne dass dabei die Rollladenwalze gedreht würde. Dieser sich durch die Summe aller Spalte ergebende Betrag könnte unter Umständen ausreichen, um in das Gebäude einzudringen. Aber auch ein kleinerer Betrag kann das Eindringen ermöglichen, nämlich dann, wenn der Einbrecher den Rollladen so weit nach oben schiebt, dass er dessen unteren Rand ergreifen und gewaltsam nach aussen biegen oder knicken kann.Devices are also known which operate the roller shutters automatically lock when it reaches its closed position. For example, shows EP-A1-0 043 021 an automatic securing of a roller shutter, in which the roller shutter roller is blocked when the roller shutter is closed. With many shutters nowadays the slats are connected to each other so that they an amount can be pulled apart to make one between themselves Gap to allow air and light to pass through. Such is a roller shutter adequately secured with a device of this type only if it is so it is largely closed that all the slats are in contact with each other. Otherwise a burglar could raise the lower end of the shutter so far slide until all gaps between the slats are closed without that the roller shutter roller would be turned. This stands out through the sum amount in all columns may be sufficient to include in the To invade buildings. But even a smaller amount can penetrate enable, namely if the burglar so far after the roller shutter pushes up that he grips the bottom edge and forcibly outwards can bend or kink.
Dieser zuletzt geschilderte Nachteil wird durch eine Vorrichtung behoben, wie sie in der EP-A1-0 750 094 offenbart ist. Bei dieser Vorrichtung ist im Bereich des unteren Endes des Rollladens mindestens ein Riegel vorgesehen, der um eine parallel zum unteren Ende des Rollladens angeordnete Achse schwenkbar ist und in der Schliessstellung des Rollladens einen an einer Rollladenführung oder Gebäudeöffnung fest angebrachten Sperrteil hintergreift. Zum Entriegeln dieser Vorrichtung ist jedem Riegel ein nach oben verjüngtes Entriegelungselement zugeordnet. Ein durch die Rollladenwalze betätigter Mechanismus sorgt dafür, dass beim Betätigen des Rollladens in Öffnungsrichtung dieses Entriegelungselement durch eine Betätigungsstange angehoben wird, um den Riegel aus dem Eingriffsbereich des Sperrteils zu schwenken, bevor das untere Ende des Rollladens angehoben wird. Diese Vorrichtung ist in ihrem Aufbau relativ kompliziert, teuer und störungsanfällig.This disadvantage described last is eliminated by a device, as disclosed in EP-A1-0 750 094. In this device is at least one latch is provided in the area of the lower end of the roller shutter, the axis arranged parallel to the lower end of the roller shutter is pivotable and in the closed position of the roller shutter on a roller shutter guide or building opening engages behind the fixed blocking part. To unlock this device, each bolt is tapered upwards Unlocking element assigned. A mechanism operated by the roller shutter roller ensures that when the roller shutter is actuated in the opening direction this unlocking element is raised by an actuating rod, to pivot the latch out of the engagement area of the locking member before the lower end of the roller shutter is raised. This device is in her Construction relatively complicated, expensive and prone to failure.
Beide der vorstehend geschilderten Vorrichtungen weisen zudem den Nachteil auf, dass sie sich nicht für den nachträglichen Anbau an einen bestehenden Rollladen eignen.Both of the devices described above also have the disadvantage that they are not suitable for retrofitting to an existing one Roller shutters.
Eine Verriegelungsvorrichtung für einem Rollladen entsprechend dem Oberbegriff des Anspruch 1 zeigt auch die FR-A-605 272.A locking device for one Roller shutters according to the generic term of Claim 1 also shows FR-A-605 272.
Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Verriegelungsvorrichtung vorzuschlagen, die den Rollladen beim Erreichen seiner Schliessstellung automatisch zuverlässig verriegelt und gegen ein Hochschieben von aussen sichert, die einfach aufgebaut ist und kostengünstig hergestellt werden kann und die sich insbesondere auch zum nachträglichen Anbau an bestehende Rollläden eignet.The present invention is based on this prior art the task of proposing a locking device, which automatically and reliably controls the roller shutter when it reaches its closed position locked and secured against pushing up from the outside, which is easy to set up is and can be produced inexpensively and which in particular Also suitable for retrofitting to existing roller shutters.
Diese Aufgabe wird durch eine Verriegelungsvorrichtung der eingangs genannten Art gelöst, welche dadurch gekennzeichnet ist, dass der Schwenkhebel derart mit dem mindestens einen Riegelelement wirkverbunden ist, dass er in dessen Freigabestellung mindestens annähernd rechtwinklig zur Bewegungsrichtung des Rollladens ausgerichtet ist und dass ein Federmittel vorgesehen ist, das den Schwenkhebel in die Freigabestellung des Riegelelementes und nach Überschreiten eines Totpunktes in die Sperrstellung des Riegelelementes drängt, derart, dass das Riegelelement automatisch in seine Sperrstellung gebracht wird, wenn der Schwenkhebel kurz vor dem Erreichen der Schliessstellung des Verschlussorgans durch einen Anschlag aus der Freigabestellung des Riegelelementes über den Totpunkt bewegt wird.This task is accomplished by a locking device at the beginning mentioned type, which is characterized in that the Swivel lever operatively connected to the at least one locking element is that in its release position it is at least approximately at right angles to the Direction of movement of the roller shutter is aligned and that a spring means is provided that the pivot lever in the release position of the locking element and after passing a dead center into the locking position of the locking element urges such that the locking element automatically in its Lock position is brought when the swivel lever just before reaching the closing position of the closure member by a stop from the release position of the locking element is moved over the dead center.

Figur 1 ist eine schematische Ansicht vom Inneren eines Gebäudes
auf eine erste Ausführungsart einer am unteren Ende eines Rollladens anzuordnenden
erfindungsgemässen Verriegelungsvorrichtung. Der Rollladen selbst
ist bei dieser Darstellung aus Gründen der Übersichtlichkeit nicht dargestellt.
Der Pfeil 2 bezeichnet die Schliessrichtung des Rollladens, welcher sich in der
Darstellung nach Figur 1 kurz vor seiner Schliessstellung befindet. Mit 1 ist die
Leibung und mit 5 die Fensterbank bezeichnet. Zwei Riegelelemente 3 sind
nach aussen verschiebbar am Rollladen angeordnet und dazu bestimmt, in der
Schliessstellung des Rollladens an der Leibung angeordnete Sperrteile 4 zu
hintergreifen, um ein Öffnen des Rollladens zu verhindern. Mit jedem Riegelelement
3 ist eine kleine Zahnstange 6 verbunden, die mit einem zentral angeordneten
Zahnrad 7 kämmt. Das Zahnrad 7 und die Zahnstangen 6 können
beispielsweise Stanzteile sein. Durch das Drehen des Zahnrades 7 im Uhrzeigersinn
werden die Riegelelemente 3 nach aussen verschoben und in ihre
Sperrstellung gebracht. Mit der Achse 8 des Zahnrades 7 ist ein Schwenkhebel
9 drehfest verbunden, und zwar so, dass er in der Freigabestellung der Riegelelemente
3 etwa parallel zu diesen ausgerichtet ist. Der Anschlag, der diese
Stellung des Schwenkhebels begrenzt, ist in diesem Beispiel dadurch gegeben,
dass das Zahnrad 7 das Ende der Verzahnung der Zahnstangen 6 erreicht. Eine
Feder 10 ist mit ihrem einen Ende mit dem Schwenkhebel 9 und mit ihrem
anderen Ende mit einem ortsfest am Rollladen angeordneten Teil, der im vorliegenden
Beispiel die Gestalt eines Winkels 11 hat, befestigt. Dabei verläuft die
Längsachse der Feder 10, wie man in Figur 1 sieht, etwas unterhalb der Achse
8 des Schwenkhebels 9, so dass dieser durch die Kraft der Feder in der dargestellten
Stellung gehalten wird. Am freien Ende des Schwenkhebels 9 ist eine
weitere Achse 12 angeordnet, an welcher ein Stössel 13 schwenkbar befestigt
ist. Der Stössel 13 hängt in der Darstellung gemäss Figur 1 frei nach unten und
hat die Aufgabe, an der Fensterbank 5 anzuschlagen, kurz bevor der Rollladen
seine geschlossene Stellung erreicht hat, und dabei den Schwenkhebel 9 so
weit aus der in Figur 1 dargestellten Lage zu verschwenken, dass die Längsachse
der Feder 10 oberhalb der Achse 8 des Schwenkhebels 9 verläuft. Danach
wird die Feder 10 den Schwenkhebel 9 in die in Figur 2 gezeigte obere
Endlage ziehen, die Riegelelemente 3 werden nach aussen verschoben und
der Rollladen ist verriegelt. Diese obere Endlage des Schwenkhebels 9 wird
beispielsweise dadurch bestimmt, dass der Schwenkhebel 9 am Winkel 11 anschlägt.
Ein vorstehender Anschlag 15 am Schwenkhebel 9 hält in dieser Stellung
den Stössel 13 in der gezeigten Lage, etwa rechtwinklig zum Schwenkhebel.
Anstelle des Stössels 13 kann auch ein Anschlagteil auf der Fensterbank
angeordnet sein, an dem der Schwenkhebel 9 kurz vor dem Erreichen der
Schliessstellung des Rollladens ansteht.Figure 1 is a schematic view from the inside of a building
to a first embodiment to be arranged at the lower end of a roller shutter
locking device according to the invention. The roller shutter itself
is not shown in this representation for reasons of clarity.
The arrow 2 indicates the closing direction of the roller shutter, which is in the
Representation according to Figure 1 is just before its closed position. With 1 it is

Vor dem Öffnen des Rollladens muss die Verriegelungsvorrichtung
manuell in ihre Freigabestellung gebracht werden. In der Darstellung gemäss
Figur 3 ist der Schwenkhebel 9 entgegen der Kraft der Feder 10 bereits so weit
aus der Position gemäss Figur 2 im Gegenuhrzeigersinn verschwenkt worden,
bis der Stössel 13 die Fensterbank 5 berührt. Dabei sind die Riegelelemente 3
gegenüber Figur 2 ein Stück nach innen verschoben worden. Beim Weiterschwenken
des Schwenkhebels 9 wandert der Berührungspunkt des Stössels
13 auf der Fensterbank 5 nach links, so dass der Stössel die Bewegung des
Schwenkhebels 9 nicht behindert. Diese Ausweichbewegung des Stössels 13
wird durch eine an ihm vorgesehene Abschrägung 14 begünstigt. Bei der oben
erwähnten Variante, bei der anstelle des Stössels ein Anschlagteil auf der Fensterbank
vorgesehen ist, muss der Anschlagteil verschiebbar sein, damit der
Schwenkhebel in die horizontale Lage gebracht werden kann. Während der
Schwenkbewegung des Schwenkhebels wandert die Mittellinie der Feder 10
nach unten, so dass sich das durch die Feder auf den Schwenkhebel ausgeübte
Drehmoment einem Totpunkt nähert. Dieser Totpunkt ist erreicht, wenn die
Mittellinie der Feder 10 genau über der Achse 8 des Schwenkhebels 9 liegt.
Figur 4 zeigt die Vorrichtung nach dem Überschreiten des Totpunktes in ihrer
Freigabestellung, in der sie durch die Feder 10 gehalten wird. Sobald der nun
entriegelte Rollladen etwas angehoben wird, hängt der Stössel 13 infolge der
Schwerkraft nach unten und nimmt wieder die in Figur 1 dargestellte Stellung
ein. Insbesondere dann, wenn die Schliessrichtung 2 des Rollladens nicht vertikal
ist, kann eine weitere Feder am Stössel angeordnet werden, welche diesen
gegen den Schwenkhebel zieht. Es ist aber auch möglich, die Feder 10 am
Stössel 13 angreifen zu lassen, so dass gleichzeitig mit der vorher beschriebenen,
den Schwenkhebel betreffenden Aufgabe der Feder 10 auch der Stössel
immer gegen eine Lage rechtwinklig zum Schwenkhebel gedrängt wird.Before opening the roller shutter, the locking device
manually brought into their release position. According to the presentation
Figure 3 is the
Figur 5 zeigt einen Querschnitt durch eine andere Ausführungsart
der erfindungsgemässen Verriegelungsvorrichtung in der Sperrstellung entsprechend
Figur 2 in einem gegenüber Figur 2 etwas grösseren Massstab. Am
unteren Ende des aus Lamellen 16 bestehenden Rollladens ist ein hohles Abschlussprofil
17 angeordnet, das Teile der Verriegelungsvorrichtung, insbesondere
die Riegelelemente 3, die Zahnstangen 6 und das Zahnrad 7 in seinem
Inneren aufnimmt. Eine durch eine Deckplatte 19 verschlossene Öffnung 18 in
der Wand des Abschlussprofils 17 erlaubt den Ein- und Ausbau der genannten
Teile. Der an seinem freien Ende abgewinkelte Schwenkhebel 9 ragt durch einen
bogenförmigen Schlitz 21 einer Abdeckhaube 20, damit er von Hand in seine
Freigabestellung gebracht werden kann, wie dies weiter oben im Zusammenhang
mit den Figuren 1 bis 4 beschrieben wurde.Figure 5 shows a cross section through another embodiment
corresponding to the locking device according to the invention in the locked position

In Figur 6 sieht man einen Grundriss der Verriegelungsvorrichtung
gemäss Figur 5. Seitliche Führungsprofile 22, von denen in der Figur nur eines
sichtbar ist, sind als Doppelkammerprofil ausgebildet, wobei in der Trennwand
zwischen den beiden Kammern im Bereich der Schliessstellung des Rollladens
eine Öffnung 23 vorgesehen ist. Diese Öffnung hat dieselbe Funktion wie der
Sperrteil 4 in den Ausführungsarten gemäss Figur 1 bis 4, 7 und 8, indem sie
von dem im Abschlussprofil aufgenommenen Riegelelement 3 in seiner Sperrstellung
durchdrungen wird. Diese Ausführungsart der Verriegelungsvorrichtung
ist dafür vorgesehen, werkseitig in Rollläden eingebaut zu werden. In Figure 6 you can see a floor plan of the locking device
according to Figure 5. Lateral guide profiles 22, of which only one in the figure

Die in Figur 7 dargestellte Ausführungsart der Verriegelungsvorrichtung
ist insbesondere für einen nachträglichen Anbau an bestehende Rollläden
konzipiert. Die Teile der Vorrichtung, welche im Ausführungsbeispiel gemäss
Figur 5 im Abschlussprofil 17 angeordnet sind, nämlich die Riegelelemente 3,
die Zahnstangen 6 und das Zahnrad 7, sind hier in einem Hohlprofil 29 aufgenommen,
welches einfach am Abschlussprofil 17 eines beliebigen Rollladens
befestigt, beispielsweise angeschraubt werden kann. Das in diesem Beispiel
gezeigte Führungsprofil 24 bietet nicht die Möglichkeit, eine Öffnung 23 anzubringen,
weshalb hier auf den weiter oben erwähnten Sperrteil 4 zurückgegriffen
wird. Dieser Sperrteil hat hier die Gestalt eines Winkels und ist mittels
Schrauben 26 in der Leibung befestigt. Die Riegelelemente 3 weisen eine zum
Gebäudeinneren hin versetzte Verlängerung 30 auf, so dass sie den Sperrteil 4
hintergreifen und den Rollladen verriegeln können. Jede mit einem Riegelelement
3 verbundene Verlängerung 30 ist am Abschlussprofil 17 in einer Führung
25 gehalten.The embodiment of the locking device shown in Figure 7
is particularly suitable for retrofitting to existing roller shutters
designed. The parts of the device which according to the
Schliesslich zeigt Figur 8 anhand einer Darstellung ähnlich Figur 1,
dass die Umsetzung der Schwenkbewegung des Schwenkhebels 9 nicht unbedingt
mittels Zahnrad 7 und Zahnstange 6 erfolgen muss. Statt dessen ist hier
mit der Achse 8 des Schwenkhebels 9 ein Hebel 27 drehfest verbunden, an
dessen beiden Enden je ein Lenker 28 angeordnet ist, welche ihrerseits mit den
Riegelelementen 3 verbunden sind.Finally, FIG. 8 shows a representation similar to FIG. 1,
