Description

Die Erfindung betrifft ein Sicherungsblockademittel für ein Deckenlauftor, das eine Sicherungseinheit aufweist, wobei die Sicherungseinheit im Sicherungszustand ein Blockieren in der Führung des Deckenlauftores bewirkt, indem die Sicherungseinheit dann an der Führungsschiene zum Anliegen bzw. Einrasten kommt, wobei das Sicherungsblockademittel mit dem Führungsseil bzw. der Führungskette des Deckenlauftores verbunden ist, wobei sich durch eine mechanische Vorspannung des Führungsseils bzw. der Führungskette die Sicherungseinheit im Funktionszustand befindet, wobei die Sicherungseinheit in den Sicherungszustand übergeht, wenn das Führungsseil bzw. die Führungskette die Verbindung zum Sicherungsblockademittel verliert und/oder nicht mehr mit einer mechanischen Vorspannung beaufschlagt ist, wobei die Sicherungseinheit als quer zu der Bewegungsrichtung des Panzers des Deckenlauftores angeordneter, axial verschiebbarer Bolzen ausgebildet ist, der durch ein elastisches Mittel vorgespannt ist.The invention relates to a security blocking means for a Deckenlauftor having a securing unit, wherein the securing unit in the securing state causes a blockage in the leadership of the overhead door by the securing unit then comes to the guide rail for engagement or latching, wherein the securing blocking means with the guide cable or the guide chain of the overhead door is connected, wherein the securing unit is in functional condition by a mechanical bias of the guide cable or the guide chain, wherein the securing unit merges into the securing state when the guide cable or the guide chain loses the connection to the safety locking means and / or not more is subjected to a mechanical bias, wherein the securing unit is formed as arranged transversely to the direction of movement of the tank of the overhead running gate, axially displaceable bolt, which vorges by an elastic means is perverted.

Derartige Deckenlauftore sind beispielsweise aus der DE 37 10 237 A1 , der FR 2 809 763 A1 und der NL 53 486 C bekannt. Diese werden insbesondere als Tore von Garagen eingesetzt. Diese Deckenlauftore können von Hand betätigbar sein oder auch mittels eines Elektroantriebes. Auch wenn das Deckenlauftor mittels eines Elektroantriebes betätigbar ist, kann der Elektroantrieb ausgehängt werden, um das Deckenlauftor beispielsweise bei einem Stromausfall dann von Hand betätigen zu können.Such overhead doors are for example from the DE 37 10 237 A1 , of the FR 2 809 763 A1 and the NL 53 486 C known. These are used in particular as gates of garages. These overhead doors can be operated by hand or by means of an electric drive. Even if the overhead door can be actuated by means of an electric drive, the electric drive can be unhooked to then manually operate the overhead door, for example in case of power failure.

Wenn sich ein Deckenlauftor in einer Führungsschiene bewegt, hängt die Gewichtskraft, mit der das Deckenlauftor nach unten zieht, zunächst davon ab, wie weit das Deckenlauftor nach oben gezogen ist. Das Deckenlauftor zieht mit der Gewichtskraft der in der senkrechten Laufschiene befindlichen Glieder des Panzers nach unten. Befindet sich das Deckenlauftor in seiner untersten Stellung, zieht das Deckenlauftor mit der größten Gewichtskraft nach unten. Befindet sich das Deckenlauftor in seiner obersten Stellung, zieht das Deckenlauftor praktisch gar nicht nach unten.When a ceiling runner moves in a guide rail, the weight with which the overhead runner pulls down first depends on how far the overhead runner is pulled up. The Deckenlauftor pulls down with the weight of the located in the vertical track rail members of the tank. If the overhead door is in its lowest position, the overhead door pulls down with the greatest weight. If the overhead door is in its uppermost position, the overhead door practically does not pull down.

Die Gewichtskraft, mit der das Deckenlauftor nach unten zieht, verändert sich dabei gleichmäßig zwischen diesen beiden Werten abhängig von der Position des Deckenlauftores.The weight with which the overhead door pulls down changes evenly between these two values depending on the position of the overhead door.

Um einen gleichmäßigen Zug zu erreichen, ist es daher bekannt, an dem Deckenlauftor eines oder mehrere Führungsseile anzubringen, die mit einer Federkraft beaufschlagbar sind. Dadurch sollen die Veränderungen, die sich durch die unterschiedlichen Gewichtskräfte ergeben, mit denen das Deckenlauftor abhängig von seiner Position nach unten zieht, durch eine entsprechende Federkraft zumindest nahezu ausgeglichen werden. In Summe sollen sich also in der obersten Stellung des Deckenlauftores gegenüber der untersten Stellung des Deckenlauftores solche Federkräfte ergeben, dass diese zumindest in etwa der Gewichtskraft entsprechen, mit der das Deckenlauftor in seiner untersten Stellung nach unten zieht.In order to achieve a uniform train, it is therefore known to attach to the Deckenlauftor one or more guide cables, which can be acted upon by a spring force. Thereby the changes that result from the different weight forces with which the overhead door pulls depending on its position down, are at least almost compensated by a corresponding spring force. In sum, therefore, should in the uppermost position of the overhead running door opposite the lowermost position of the overhead running gate such spring forces arise that they at least approximately correspond to the weight with which the overhead door pulls in its lowest position down.

Um eine ungewollte und unkontrollierte Bewegung des Deckenlauftores auch bei einer Funktionsstörung weitgehend zu vermeiden, ist es bekannt, beispielsweise aus der EP 1 260 665 A2 , ein Sicherungsblockademittel an einem Deckenlauftor vorzusehen. Insbesondere soll hiermit eine Abwärtsbewegung des Deckenlauftores zumindest dann blockiert werden, wenn das Deckenlauftor mit einer Kraft oberhalb eines Grenzwertes nach unten beschleunigt wird.In order to avoid an unwanted and uncontrolled movement of the overhead door even with a malfunction largely, it is known, for example from the EP 1 260 665 A2 to provide a safety lock on a overhead door. In particular, this is intended to block a downward movement of the overhead door at least when the overhead door is accelerated downwards with a force above a limit value.

Ein ähnliches Sicherheitsblockademittel für ein Deckenlauftor ist aus DE 37 10 237 A1 bekannt, dessen Merkmale dem Oberbegriff des Anspruchs 1 entsprechen.A similar security blocker for a overhead door is off DE 37 10 237 A1 known, whose features correspond to the preamble of claim 1.

Diese Sicherungsblockademittel haben sich insgesamt als zuverlässig erwiesen. Jedoch ist hierbei nachteilig, daß die maximal erreichbare Höhe im Bereich des geöffneten Deckenlauftores durch das Sicherungsblockademittel beschränkt wird. Insbesondere bei niedrigen Garagen sowie den zunehmend in die Höhe bauenden Kraftfahrzeugen ist dies problematisch.These safety locking means have proven to be reliable overall. However, this is disadvantageous in that the maximum achievable height in the area of the open overhead door is limited by the Sicherungsblockademittel. This is problematic, in particular with low garages as well as the increasingly high-rise motor vehicles.

Aufgabe der Erfindung ist es daher, ein Sicherungsblockademittel für Deckenlauftore zu schaffen, das auch über größere Zeiträume zuverlässig funktioniert.The object of the invention is therefore to provide a Sicherungsblockademittel for overhead doors, which works reliably for longer periods.

Dies wird erfindungsgemäß durch die Merkmale des Anspruchs 1 erreicht. Das Führungsseil bzw. die Führungskette ist unterhalb des Bolzens an dem Endstab befestigt und durch einen axial angeordneten Schlitz im freien Ende des Bolzens geführt.This is achieved according to the invention by the features of claim 1. The guide cable or chain is attached below the bolt to the end bar and guided by an axially disposed slot in the free end of the bolt.

Dies stellt eine einfache, jedoch zuverlässige Möglichkeit dar, den Bolzen bei Nachlassen der Seil- bzw. Kettenspannung in die Betätigungsstellung zu bringen.This is a simple, but reliable way to bring the bolt on release of the rope or chain tension in the operating position.

Durch die Anbringung der Sicherungseinheit quer zu der Bewegungsrichtung des Panzers des Deckenlauftores wird erreicht, dass das Deckenlauftor eine größere erreichbare Höhe hat. Zudem wird durch die Anordnung der Sicherungseinheit quer zur Bewegungsrichtung ein schnelleres und sichereres Blockieren sichergestellt, wenn das Führungsseil bzw. die Führungskette ganz abreißt oder ihre mechanische Vorspannung verliert.By attaching the fuse unit transversely to the direction of movement of the tank of the overhead door is achieved that the overhead door has a greater reachable height. In addition, a faster and safer locking is ensured by the arrangement of the securing unit transverse to the direction of movement when the guide cable or the guide chain breaks completely or loses its mechanical bias.

Vorteilhaft wird mit der vorliegenden Erfindung erreicht, dass auch bei einem elektrisch betriebenen Deckenlauftor die Sicherheit in obigem Sinne verbessert wird, wenn der Elektroantrieb abgekoppelt wurde, was beispielsweise bei einem Stromausfall der Fall sein kann, um dann das Deckenlauftor durch eine Handbetätigung bewegen zu können. In diesem Fall wird durch den Einsatz der vorliegenden Erfindung das Deckenlauftor blockiert, wenn unter diesen Umständen eines oder beide Führungsseile reißen sollten.Advantageously, it is achieved with the present invention that the safety is improved in the above sense even with an electrically operated overhead door when the electric drive was decoupled, which may be the case, for example in a power failure, then to move the overhead door by a manual operation can. In this case, the use of the present invention blocks the overhead runner if under these circumstances one or both guide ropes should break.

Bei einer vorteilhaften Ausgestaltung ist vorgesehen, dass das Sicherungsblockademittel am bzw. im Endstab des Panzers des Deckenlauftores angeordnet ist.In an advantageous embodiment, it is provided that the securing blockage means is arranged on or in the end bar of the tank of the overhead door.

Dies erlaubt es, das Sicherungsblockademittel einerseits vor Umwelteinflüssen zu schützen und andererseits elegant in den ohnehin vorhandenen Endstab zu integrieren.This makes it possible, on the one hand, to protect the safety blocking means against environmental influences and, on the other hand, to integrate it elegantly into the end rod, which is present anyway.

Es ist zweckmäßig, dass das Führungsseil an ein dem freien Schenkel eines Kipphebels angeordnet ist, wobei der freie Schenkel bei vorgespanntem Führungsseil im wesentlichen parallel zu dem Bolzen angeordnet ist und im entspannten Zustand nach unten wegklappbar ist.It is expedient that the guide cable is arranged on a free leg of a rocker arm, wherein the free leg is arranged in a biased guide cable substantially parallel to the bolt and in the relaxed state can be folded down.

Schließlich ist es zweckmäßig, dass Mittel zum Rückstellen und erneuten Vorspannen des Bolzens nach dessen Übergehen in den Sicherungszustand vorgesehen sind.Finally, it is expedient that means are provided for resetting and re-biasing the bolt after it has been transferred to the securing state.

Hierdurch wird es ermöglicht, nach Betätigung der Sicherungsblockademittel diese in einfacher Weise wieder zu aktivieren ohne eine Demontage des Endstabs oder der Sicherungsblockademittel vornehmen zu müssen.This makes it possible, after actuation of the Sicherungsblockademittel these in a simple way to re-activate without disassembly of Endstabs or Sicherungsblockademittel need to make.

Bei einer bevorzugten Ausgestaltung besteht die Sicherungseinheit aus einem elastischen Material, dass unter einer mechanischen Spannung in einer zumindest im wesentlichen länglichen Form gehalten wird, wenn sich die Sicherungseinheit im Funktionszustand befindet, und dass in horizontaler Richtung ausgedehnt ist, wenn sich die Sicherungseinheit im Sicherungszustand befindet.In a preferred embodiment, the securing unit is made of an elastic material that is kept under a mechanical tension in an at least substantially elongated shape when the securing unit is in the functional state and that is expanded in the horizontal direction when the securing unit is in the securing state ,

Dieses Material kann beispielsweise ein gummiartiger Kunststoff sein. Solange die zumindest eine Feder des Sicherungsblockademittels durch die mechanische Spannung des Führungsseils gespannt ist, ist das Material in Längsrichtung gestreckt. Verliert die Feder des Sicherungsblockademittels die mechanische Spannung, kann ein entsprechender Druck auf das Material ausgeübt werden, so dass sich das Material in der Breit ausdehnt. Indem das Material dann gegen die Führungsschiene drückt, kann durch die entstehenden Reibungskräfte das Deckenlauftor blockiert werden.This material may for example be a rubber-like plastic. As long as the at least one spring of the Sicherungsblockademittels is tensioned by the tension of the guide cable, the material is stretched in the longitudinal direction. If the spring of the locking block loses the mechanical tension, a corresponding pressure can be exerted on the material so that the material expands in the width. By the material then presses against the guide rail, the overhead running gate can be blocked by the resulting frictional forces.

Bei einer bevorzugten Ausgestaltung besteht die Sicherungseinheit aus einem beweglichen Teil, das keine Berührung mit der Führungsschiene hat, wenn sich die Sicherungseinheit im Funktionszustand befindet und das im Sinne einer Reibverbindung oder einer Rastverbindung an der Führungsschiene anliegt, wenn sich die Sicherungseinheit im Sicherungszustand befindet.In a preferred embodiment, the securing unit consists of a movable part which has no contact with the guide rail when the securing unit is in the functional state and which abuts the guide rail in the sense of a frictional connection or a latching connection when the securing unit is in the securing state.

Ein Ausführungsbeispiel der vorliegenden Erfindung ist in den Zeichnungen dargestellt. Es zeigt dabei:

Fig. 1:

An embodiment of the present invention is shown in the drawings. It shows:
Fig. 1:
the safety locking means with prestressed guide cable
Fig. 2
the safety blockage means with decreasing guide rope tension.

Figur 1 zeigt ein Sicherungsblockademittel 1. Es sind weiterhin seitlich Begrenzungen einer Führungsschiene 2 eines Deckenlauftores zu sehen, von dem die unterste Lamelle 4, der sogenannte Endstab, dargestellt ist. An dem der untersten Lamelle 4 sind weiterhin Rollen 5 und 6 angebracht. Über diese Rollen ist der Panzer des Deckenlauftores in der Führungsschiene bewegbar. FIG. 1 shows a fuse blocking means 1. It can also be seen laterally boundaries of a guide rail 2 of a overhead door, of which the bottom plate 4, the so-called end bar, is shown. At the bottom of the slat 4 rollers 5 and 6 are still attached. About these roles of the tank of the overhead door is movable in the guide rail.

In einer Ausnehmung der untersten Lamelle 4 ist als Sicherungseinheit 3 ein quer zu der Bewegungsrichtung des Panzers des Deckenlauftores, axial verschiebbarer Bolzen 3 angeordnet, der durch ein elastisches Mittel 7, hier eine Feder, vorgespannt ist. Der Bolzen 3 weist an seinem freien Ende einen in vertikaler Richtung angeordneten axialen Schlitz auf.In a recess of the bottom plate 4 is arranged as a securing unit 3, a transversely to the direction of movement of the tank of Deckenlauftores, axially displaceable bolt 3, which is biased by an elastic means 7, here a spring. The bolt 3 has at its free end a arranged in the vertical direction axial slot.

Es ist weiterhin ein Führungsseil 8 zu sehen, das in ein als Kipphebel ausgebildetes Aufnahmeteil 9 des Sicherungsblockademittels 1 einhängbar und befestigbar ist. Dieses Aufnahmeteil 9 ist an der Unterseite der untersten Lamelle 4 befestigt und um eine Achse schwenkbar. Das Führungsseil 8 ist durch den axial angeordneten Schlitz 10 im freien Ende des Bolzens 3 geführt.Furthermore, a guide cable 8 can be seen which can be suspended and fastened in a receiving part 9 of the locking blockage means 1 designed as a rocker arm. This receiving part 9 is attached to the underside of the bottom plate 4 and pivotable about an axis. The guide cable 8 is guided through the axially disposed slot 10 in the free end of the bolt 3.

Wenn das Führungsseil 8 eine mechanische Vorspannung aufweist (Fig. 1), wird das Aufnahmeteil 9 durch das Führungsseil 8 in die obere Stellung gebracht, bei der es an der Unterseite des Bolzens 3 anliegt.If the guide cable 8 has a mechanical bias ( Fig. 1 ), the receiving part 9 is brought by the guide cable 8 in the upper position, in which it rests against the underside of the bolt 3.

Läßt die Spannung des Führungsseils 8 nach (Fig. 2), so bewegt sich der Bolzen 3 aufgrund seiner Vorspannung quer zu der Bewegungsrichtung des Panzers des Deckenlauftores aus der letzten Lamelle 4 bzw. Endleiste heraus und gleitet mit seiner Vorderkante an der Wand der Führungsschiene 2 entlang. Der Kipphebel 9 kippt nach unten weg.Lets the tension of the guide rope 8 after ( Fig. 2 ), so the bolt 3 moves due to its bias transversely to the direction of movement of the tank of the overhead door from the last slat 4 or Endleiste out and slides with its front edge on the wall of the guide rail 2 along. The rocker arm 9 tilts down.

An dieser sind in bestimmten Abständen Bohrungen 11 von zumindest dem Durchmesser des Bolzens 3 vorgesehen, so daß der Bolzen 3 aufgrund seiner Vorspannung in die nächstuntere Bohrung 11 eintritt und das Deckenlauftor gegen weiteres Abstürzen sichert.At this intervals holes 11 are provided by at least the diameter of the bolt 3 at certain intervals, so that the bolt 3 enters due to its bias in the next lower hole 11 and the Deckenlauftor ensures against further crashes.

Nach einer solchen Betätigung kann der Bolzen 3 über eine Öffnung in der Endleiste manuell wieder in die Ausgangsstellung (Fig. 1) zurückgeführt werden, wobei das elastische Mittel 7 erneut gespannt wird.After such an operation, the bolt 3 can be manually returned to the starting position via an opening in the end bar (FIG. Fig. 1 ), the elastic means 7 being tensioned again.
