Description

"Vorrichtung zur Sicherung eines mittels Betätigungsgurt bedienbaren Rolladens" "Device for securing a roller shutter that can be operated by means of an operating belt"
Die Erfindung bezieht sich gattungsgemäß auf eine Vorrichtung zur Sicherung eines mittels Betätigungsgurt bedienbaren Rolladens gegen unbefugtes Hochschieben, - mitThe invention generally relates to a device for securing a roller shutter that can be operated by means of an actuating belt against unauthorized pushing up, with
Gurttrommel, die zwei Trommelscheiben aufweist,Belt drum, which has two drum disks,
Sicherungshebel mit Sperrklinke,Safety lever with pawl,
Walzenkappe mit Achsstummel undRoller cap with stub axle and
Montageplatte, an der der Sicherungshebel gelagert ist.Mounting plate on which the safety lever is mounted.
wobei die Gurttrommel auf die Walzenkappe aufsetzbar ist und zumindest eine der Trommelscheiben über ihren Umfang verteilte Sperrelemente besitzt, gegen die die Sperrklinke in Sicherungsstellung des Sicherungshebels anlegbar ist, wobei der Sicherungshebel eine Führung für den Betätigungsgurt aufweist und durch Ausüben einer Zugkraft auf den Betätigungsgurt aus der Sicherungsstellung in eine Freistellung schwenkbar ist, - Bei derartigen Vorrichtungen ist tunlich der Rolladen durch direktes Aufschrauben des obersten Stabes auf die Rolladenwalze an diese angeschlossen, damit der herabgelassene Rolladen insoweit nicht durch ein Zuggurtspiel , wenn auch begrenzt, hochschiebbar ist.wherein the belt drum can be placed on the roller cap and has at least one of the drum disks distributed over its circumference locking elements against which the pawl can be placed in the securing position of the securing lever, the securing lever having a guide for the actuating belt and by exerting a tensile force on the actuating belt from the Secured position can be pivoted into an exemption, - With such devices, the roller shutter is directly connected to the roller shutter roller by screwing the top bar directly onto it, so that the lowered roller shutter cannot be pushed up, albeit to a limited extent, by a tension belt play.
Bei der bekannten gattungsgemäßen Vorrichtung (DE-OS 22 34 879) trägt die Montageplatte den Sicherungshebel, der als einarmiger Hebel ausgeführt und an seinem, im montierten Zustand unteren Ende gelagert ist. Die Montageplatte ist mit ihrer Ebene parallel zur Rolladenwalze und damit parallel zur Ebene des Rolladens angeordnet, sie kann mit einer entsprechenden Wand des Rolladenkastens zusammenfallen oder darauf aufgesetzt sein. Die Montageplatte trägt außerdem eine Belastungsfeder für den Sicherungshebel und weitere Führungen für den Betätigungsgurt in Form von Gurtrollen . Das ist aufwendig und kann nicht leicht montiert werden. Insbesondere ist es nicht möglich, die beschriebenen Bauteile der Vorrichtung zu einem Bauelementensatz zu gestalten, der ohne weiteres bei praktisch allen gebräuchlichen Rolläden zum Zwecke der Verwirklichung einer zusätzlichen Einbruchsicherung nachträglich eingebaut werden kann.In the known generic device (DE-OS 22 34 879), the mounting plate carries the locking lever, which is designed as a one-armed lever and is mounted at its lower end in the assembled state. The mounting plate is arranged with its level parallel to the roller shutter roller and thus parallel to the level of the roller shutter, it can coincide with or be placed on a corresponding wall of the roller shutter box. The mounting plate carries also a load spring for the safety lever and other guides for the operating belt in the form of belt rollers. This is complex and cannot be easily assembled. In particular, it is not possible to design the described components of the device as a set of components which can be easily retrofitted to practically all conventional roller shutters for the purpose of realizing an additional burglar protection.
Grundsätzlich ist es bekannt, bei einer Vorrichtung der angegebenen Zweckbestimmung mit einer Montageplatte zu arbeiten, die stirnseitig vor der Rolladenwalze angebracht wird (DE-GM 72 42 333) , hier wird jedoch mit einem zusätzlichen Zahnrad gearbeitet, welches eine Sperrklinke aufweist. Dadurch wird außerdem die Baulänge der Rolladenwalze nicht unbeachtlich vergrößert, so daß die bekannte Vorrichtung nicht ohne weiteres bei allen üblichen Rolläden eingebaut werden kann.Basically, it is known to work with a device of the specified purpose with a mounting plate which is attached to the front of the roller shutter roller (DE-GM 72 42 333), but here an additional gear is used which has a pawl. As a result, the overall length of the roller shutter roller is not increased insignificantly, so that the known device cannot be easily installed in all conventional roller shutters.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Vorrichtung zu vereinfachen und so weiter auszubilden, daß sie ohne Schwierigkeiten bei allen üblichen Rolläden eingebaut werden kann und daß ihre Bauteile zu einem entsprechenden Bauelementensatz zusammengefaßt werden können.The object of the invention is to simplify the generic device and to further develop it in such a way that it can be installed in all conventional roller shutters without difficulty and that its components can be combined to form a corresponding set of components.
Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Montageplatte ein Lager für den Achsstummel der Walzenkappe aufweist und auf diesen aufgesetzt sowie gleichzeitig als Lagerplatte für die Rolladenwalze ausgeführt und dazu stirnwandseitig im Rolladenkasten zu befestigen ist, daß der Sicherungshebel als zweiarmiger Hebel ausgeführt ist, der einen Hebelarm aufweist, welcher die Führung für den Betätigungsgurt trägt, sowie einen weiteren Hebelarm besitzt, von dem die Sperrklinke abgewinkelt ist, und daß der Siehe rungshebel im montierten Zustand neben und oberhalb der mit Sperrelementen versehenen Trommelscheibe an der Montageplatte gelagert ist sowie mit der Sperrklinke diese Trommelscheibe überfaßt. - Die Erfindung nutzt die Tatsache, daß die heute gebräuchlichen Rolläden in der beschriebenen Weise mit Walzenkappen ausgerüstet sind, die weitgehend normiert sind, und daß die Achsstummel der Walzenkappen ohnehin im Rolladenkasten gelagert werden müssen. Die bei der gattungsgemäßen Vorrichtung vorhandene Montageplatte erfüllt bei der erfindungsgemäßen Vorrichtung eine Doppelfunktion, weil sie sowohl als Lager für den Achsstummel als auch zur Lagerung des Sicherungshebels dient. Das Lager für den Achsstummel kann ein Kugellager sein. Die Montageplatte und der Sicherungshebel werden als Bauelementensatz durch die Gurttrommel ergänzt, von der zumindest eine Trommelscheibe in der beschriebenen Weise mit Sperr elementen ausgerüstet ist. Die Sperrelemente können Zähne oder entsprechende Ausnehmungen sein. Damit der Rolladen auf einfache Weise und ohne Beeinträchtigung durch die Vorrichtung herabgelassen werden kann , sind die Sperrelemente in dieser Bewegungsrichtung der Gurttrommel von der Sperrklinke überfahrbar bzw. unter der Sperrklinke her bewegbar, während die Blockierung bei der anderen Bewegungsrichtung der Gurttrommel erfolgt.To achieve this object, the invention teaches that the mounting plate has a bearing for the stub shaft of the roller cap and placed on it and at the same time designed as a bearing plate for the roller shutter roller and to be attached to the front wall side in the roller shutter box that the locking lever is designed as a two-armed lever that has a lever arm which carries the guide for the actuating belt, and has another lever arm from which the pawl is angled, and that the See tion lever is mounted in the assembled state next to and above the drum disk provided with locking elements on the mounting plate and covers this drum disk with the pawl. - The invention makes use of the fact that the roller shutters used today are equipped in the manner described with roller caps, which are largely standardized, and that the stub axles of the roller caps must be stored in the roller shutter box anyway. The mounting plate present in the generic device fulfills a double function in the device according to the invention because it serves both as a bearing for the stub axle and for mounting the securing lever. The bearing for the stub axle can be a ball bearing. The mounting plate and the safety lever are supplemented as a set of components by the belt drum, of which at least one drum pulley is equipped with locking elements in the manner described. The locking elements can be teeth or corresponding recesses. So that the roller shutter can be lowered in a simple manner and without being impaired by the device, the locking elements can be passed over by the pawl in this direction of movement of the belt drum or can be moved under the pawl while the blocking takes place in the other direction of movement of the belt drum.
Damit die erfindungsgemäße Vorrichtung ohne Schwierigkeiten bei allen üblichen Rolläden eingesetzt werden kann und dazu auch als Bauelementensatz in Verkehr gebracht werden kann , empfiehlt die Erfindung, daß die Montageplatte eine Mehrzahl von nach einem Raster verteilten Bohrungen für Befestigungsschrauben zur Befestigung im Rolladenkasten aufweist. Entsprechend kann die Montageplatte eine Mehrzahl von nach einem Raster verteilten Bohrungen für die Lagerung des Sicherungshebels aufweisen . Der Sicherungshebel besitzt zweckmäßigerweise eine Mehrzahl von mit Abstand voneinander angeordneten Bohrungen für die Aufnahme eines Lagerbolzens, so daß Hebelarme unterschiedlicher Länge einrichtbar sind. Das ist insbesondere für eine bevorzugte Ausführungsform der Erfindung vorteilhaft, bei der die Betätigung des Sicherungshebels in die Sicherungsstellung hinein unter Einwirkung der Schwerkraft erfolgt. Es kann aber auch mit einer entsprechenden Belastungsfeder gearbeitet werden, die ebenfalls an der Montageplatte befestigt werden kann. Die Ausführungsform, bei der der Sicherungshebel durch Schwerkrafteinwirkung mit seiner Sperrklinke in die Sperrelemente einrastet, ist dadurch gekennzeichnet, daß der die Sperrklinke tragende Hebelarm, z. B. durch Bemessung seiner Länge, schwerer ausgebildet ist als der die Führung für den Betätigungsgurt tragende Hebelarm.So that the device according to the invention can be used without difficulty in all conventional roller shutters and can also be placed on the market as a set of components, the invention recommends that the mounting plate has a plurality of holes distributed according to a grid for fastening screws for fastening in the roller shutter box. Accordingly, the mounting plate can have a plurality of bores distributed according to a grid for the mounting of the securing lever. The locking lever expediently has a plurality of at a distance bores arranged from one another for receiving a bearing pin, so that lever arms of different lengths can be set up. This is particularly advantageous for a preferred embodiment of the invention, in which the actuation of the locking lever into the locking position takes place under the influence of gravity. However, it can also be used with a corresponding load spring, which can also be attached to the mounting plate. The embodiment in which the securing lever engages with its pawl into the locking elements by the action of gravity is characterized in that the lever arm carrying the pawl, e.g. B. by dimensioning its length, is formed heavier than the lever arm carrying the guide for the actuating belt.
Die erreichten Vorteile sind in der Einfachheit der erfindungsgemäßen Vorrichtung zu sehen, die es erlaubt, die Vorrichtung bei allen üblichen Rolläden zu installieren. Die Vorrichtung kann dazu als Bauelementensatz auf den Markt gebracht werden.The advantages achieved can be seen in the simplicity of the device according to the invention, which allows the device to be installed in all conventional roller shutters. For this purpose, the device can be brought onto the market as a set of components.
