Description

Die Erfindung betrifft ein Sicherungsblockademittel für ein Deckenlauftor nach dem Oberbegriff des Anspruchs 1.The invention relates to a security blocking means for a ceiling door after Preamble of claim 1.

Derartige Deckenlauftore sind 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 gates are known. These are used especially as gates of garages used. These overhead doors can be operated by hand or by means of a Electric drive. Even if the overhead door can be operated by an electric drive, the electric drive can be unhooked around the overhead door, for example at a Power failure can then be operated by hand.

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. Die Gewichtskraft, mit der Deckenlauftor nach unten zieht, verändert sich dabei gleichmäßig zwischen diesen beiden Werten abhängig von der Position des Deckenlauftores.If a overhead door moves in a guide rail, the weight also depends who pulls the overhead door down first depends on how far the overhead door goes is pulled up. The overhead door pulls with the weight of the vertical Track members located down the tank. The overhead door is located in 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 pulls practically not down at all. The weight with which the overhead door pulls down changes 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 smooth train, it is therefore known to have one on the overhead door or attach several guide ropes that can be loaded with a spring force. This is supposed to be the changes caused by the different weight forces with which the overhead door pulls down depending on its position a corresponding spring force can be at least almost balanced. In total should So in the top position of the overhead door compared to the bottom position of the Ceiling doors such spring forces show that they are at least roughly the weight with which the overhead door pulls down in its lowest position.

Der vorliegenden Erfindung liegt das Problem zu Grunde, eine ungewollte und unkontrollierte Bewegung des Deckenlauftores auch bei einer Funktionsstörung weitgehend zu vermeiden. The problem underlying the present invention is an unwanted and uncontrolled one Avoid movement of the overhead door even in the event of a malfunction.

Insbesondere soll eine Abwärtsbewegung des Deckenlauftores zumindest dann blockiert werden, wenn das Deckenlauftor mit einer Kraft oberhalb eines Grenzwertes nach unten beschleunigt wird.In particular, a downward movement of the overhead door is to be blocked at least then if the overhead door with a force above a limit is down is accelerated.

Dies wird erfindungsgemäß erreicht durch 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, und wobei das Sicherungsblockademittel mitsamt der Sicherungseinheit im Funktionszustand entlang der Führungsschiene des Deckenlauftores beweglich ist, 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.This is achieved according to the invention by means of a security blocking device for Ceiling gate, which has a security unit, the security unit in Locking condition causes a blockage in the guide of the overhead door by the Securing unit then comes to rest or snap into place on the guide rail, and the fuse blocking means together with the fuse unit in the functional state is movable along the guide rail of the overhead door, the Safety blocking means with the guide rope or chain of the overhead door is connected, with a mechanical pretension of the guide rope or Guide chain the fuse unit is in the functional state, the Fuse unit changes to the fuse state when the guide rope or Leading chain loses the connection to the security blocking means and / or no longer is subjected to a mechanical preload.

Dadurch kann vorteilhaft erreicht werden, dass das Deckenlauftor durch die Sicherungseinheit blockiert wird, wenn das Führungsseil bzw. die Führungskette ganz abreißt oder ihre mechanische Vorspannung verliert. Dadurch kann vorteilhaft in dieser Situation eine unkontrollierte Abwärtsbewegung des Deckenlauftors vermieden werden. Dies gilt für mechanisch betätigte Deckenlauftore.This can advantageously achieve that the overhead door through the security unit is blocked when the guide rope or chain breaks completely or theirs mechanical preload loses. This can be advantageous in this situation uncontrolled downward movement of the overhead door can be avoided. This applies to mechanically operated overhead doors.

Bei den elektrisch betätigten Deckenlauftoren ergibt sich die Position des Deckenlauftores durch die von dem Elektromotor vorgegebene Position. Solange also das Deckenlauftor mechanisch durch den Elektromotor angetrieben wird, wirkt dieser also auch als Bremse bzw. Blockiermittel für den Fall, dass eines oder beide Führungsseile reißen.With the electrically operated overhead doors, the position of the overhead doors is determined by the position specified by the electric motor. So long as the overhead door mechanically driven by the electric motor, it also acts as a brake or Blocking agent in case one or both of the guide ropes break.

Vorteilhaft wird mit der vorliegenden Erfindung aber 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 bei Führungsseile reißen sollten. What is advantageously achieved with the present invention, however, is that even with an electric operated overhead door security is improved in the above sense if the Electric drive was disconnected, which could be the case, for example, in the event of a power failure can, in order to then be able to move the overhead door by manual operation. In this Case is blocked by the use of the present invention, the overhead door if should break one of the guide ropes under these circumstances.

Bei der Ausgestaltung nach Anspruch 2 weist das Sicherungsblockademittel zumindest eine Feder auf, die sich unter mechanischer Spannung befindet, wenn das mit dem Sicherungsblockademittel verbundene Führungsseil bzw. die mit dem Sicherungsblockademittel verbundene Führungskette mechanisch vorgespannt ist, wobei durch eine mechanische Entspannung der Feder die Sicherungseinheit in den Sicherungszustand übergeht.In the embodiment according to claim 2, the security blocking means has at least one Spring that is under mechanical tension when the with the Fuse blocking means connected guide rope or the with the Fuse blocking means connected guide chain is mechanically biased, wherein by mechanical relaxation of the spring, the fuse unit in the Backup status passes.

Vorteilhaft wird dadurch die Sicherungseinheit im Funktionszustand unmittelbar durch die mechanische Spannung des Führungsseils. Da diese mechanische Spannung aber unmittelbar bewirkt, dass das Deckenlauftor nicht unkontrolliert herunter fällt, wird durch diese Ausgestaltung vorteilhaft erreicht, dass die Sicherungseinheit genau dann vom Funktionszustand in den Sicherungszustand übergeht, wenn die Kraft weg fällt, die ein unkontrolliertes Absenken des Deckenlauftores verhindert.As a result, the fuse unit in the functional state is advantageous directly through the mechanical tension of the guide rope. Because this mechanical tension but immediately ensures that the overhead door does not fall down in an uncontrolled manner Embodiment advantageously achieved that the security unit from then Functional state changes to the fuse state when the force drops off prevents uncontrolled lowering of the overhead door.

Bei der Ausgestaltung nach Anspruch 3 besteht die Sicherungseinheit aus einem elastischen Material, das unter einer mechanischen Spannung in einer zumindest im wesentlichen länglichen Form gehalten wird, wenn sich die Sicherungseinheit im Funktionszustand befindet, und das in horizontaler Richtung ausgedehnt ist, wenn sich die Sicherungseinheit im Sicherungszustand befindet.In the embodiment according to claim 3, the securing unit consists of an elastic Material that is under mechanical stress in an at least essentially elongated shape is maintained when the fuse unit is in working condition is located, and which is extended in the horizontal direction when the fuse unit in the Fuse 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 can be a rubber-like plastic, for example. As long as they do a spring of the fuse block means by the mechanical tension of the Is tensioned, the material is stretched in the longitudinal direction. Loses the pen of the Fuse blocking means the mechanical tension, a corresponding pressure can be applied the material is exercised so that the material expands in the width. By doing that Material then presses against the guide rail can be caused by the resulting Frictional forces will block the overhead door.

Bei der Ausgestaltung nach Anspruch 4 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 the embodiment according to claim 4, the securing unit consists of a movable Part that has no contact with the guide rail when the fuse unit is in the Functional state is in the sense of a friction connection or a snap connection bears against the guide rail when the fuse unit is in the fuse state located.

Im Unterschied zum Anspruch 3 wird also der Sicherungszustand nicht durch eine Materialverformung erreicht sondern durch eine Änderung der Position bzw. Lage des beweglichen Teils.In contrast to claim 3, the backup state is not by Material deformation is achieved by changing the position of the moving part.

Bei der Ausgestaltung nach Anspruch 5 ist das bewegliche Teil als Klapphebel ausgebildet, der im Funktionszustand so geklappt ist, dass dieser zumindest im wesentlichen oberflächenbündig mit dem Sicherungsblockademittel abschließt, und der im Sicherungszustand so geklappt ist, dass der Klapphebel seitlich aus dem Sicherungsblockademittels herausragt und an der Führungsschiene zum Anliegen kommt.In the embodiment according to claim 5, the movable part is designed as a folding lever, which is folded in the functional state so that it is at least essentially ends flush with the fuse blocking agent, and the in Security condition is folded so that the folding lever on the side of the Fuse block protrudes and comes to rest on the guide rail.

Dadurch behindert der Klapphebel im Funktionszustand die Bewegung des Deckenlauftores nicht. Im Sicherungszustand wird dann vorteilhaft die Klemm- bzw. Rastwirkung erzielt, indem der Klapphebel entsprechend um seine Drehachse gedreht wird. Dies kann erreicht werden, indem ein Element ein entsprechendes Drehmoment auf den Klapphebel ausübt.As a result, the folding lever hinders the movement of the overhead sliding door in the functional state Not. In the secured state, the clamping or latching effect is then advantageously achieved, by turning the folding lever around its axis of rotation. This can be achieved by an element exerting a corresponding torque on the folding lever.

Bei der Ausgestaltung nach Anspruch 6 sind Arretiermittel vorhanden, mit denen die Sicherungseinheit im Funktionszustand arretierbar ist, auch wenn keine mechanische Spannung durch das Führungsseil bzw. die Führungskette auf das Sicherungsblockademittel übertragen wird.In the embodiment according to claim 6 locking means are available with which the Fuse unit can be locked in the functional state, even if no mechanical Tension through the guide rope or chain on the safety blocking means is transmitted.

Dadurch wird vorteilhaft die Montage des Deckenlauftores vereinfacht. Das Deckenlauftor kann dann mit einer entsprechenden Arretierung in die Laufschiene eingeführt werden. Dabei ist üblicherweise das Führungsseil noch nicht eingehängt. Ohne die Arretiermittel würde also das Deckenlauftor in der Führungsschiene blockiert werden. Vorteilhaft kann also durch die Arretiermittel die Montage erleichtert werden.This advantageously simplifies the assembly of the overhead door. The overhead door can then be inserted into the track with an appropriate lock. there the guide rope is usually not yet attached. So without the locking means the overhead door in the guide rail are blocked. So can be advantageous through the Locking means the assembly can be facilitated.

Bei der Ausgestaltung nach Anspruch 7 bildet das Sicherungsblockademittel den Anschlag des Führungsseils bzw. der Führungskette an dem Panzer des Deckenlauftores.In the embodiment according to claim 7, the safety blocking means forms the stop the guide rope or chain on the armor of the overhead door.

Vorteilhaft kann durch diese Ausgestaltung Einbauraum gespart werden, indem der Anschlag gleichzeitig als Sicherungsblockademittel verwendet wird. This configuration can advantageously save installation space by the stop is also used as a security blocking agent.

Rollers 5 and 6 are also attached to the securing block means 1, via their Axes the locking device 1 continue with the lowest slat 4 of the tank of the overhead door is connected. The security blocking agent is 1 as well as the armor of the overhead door can be moved in the guide rail.

Es ist weiterhin ein Führungsseil 7 zu sehen, das in ein Aufnahmeteil 8 des Sicherungsblockademittels 1 einhängbar ist. Dieses Aufnahmeteil 8 ist mittels einer Feder 9 an dem oberen Abschluss 10 des Sicherungsblockademittels 1 abgestützt. Im übrigen kann das Aufnahmeteil 8 in dem Sicherungsblockademittel 1 entlang gleiten. Durch das Einhängemittel 11 des Führungsseils 7, das an dem oberen Abschluss des Aufnahmeteils 8 als Widerlager angreift, kann über eine mechanische Vorspannung des Führungsseil 7 die Feder 9 zusammen gedrückt werden.It can also be seen a guide rope 7, which in a receiving part 8 of the Fuse blocking device 1 can be attached. This receiving part 8 is by means of a spring 9 supported on the upper end 10 of the fuse blocking means 1. Otherwise, can slide the receiving part 8 in the fuse blocking means 1 along. By the Attachment means 11 of the guide rope 7, which at the upper end of the receiving part 8 as Abutment attacks, the spring can be mechanically pretensioned by the guide rope 7 9 are pressed together.

Wenn das Führungsseil 7 keine mechanische Vorspannung aufweist, wird das Aufnahmeteil 8 durch die sich entspannende Feder 9 nach unten gedrückt. In dem in Figur 1 gezeigten Ausführungsbeispiel wird diese Bewegung nach unten durch ein Arretiermittel 12 begrenzt.If the guide rope 7 has no mechanical pretension, the receiving part 8 pressed down by the relaxing spring 9. In that shown in Figure 1 Exemplary embodiment, this downward movement is limited by a locking means 12.

Dieses Arretiermittel 12 ist als Schraube ausgebildet, die seitlich in das Sicherungsblockademittel 1 eingedreht werden kann.This locking means 12 is designed as a screw that laterally in the Fuse blocking means 1 can be screwed in.

Es ist weiterhin eine als Klapphebel 13 aufgebildete Sicherungseinheit zu sehen, die um eine Drehachse 14 drehbar ausgebildet ist. In der in Figur 1 gezeigten Darstellung ist der Klapphebel 13 in einer dem Funktionszustand entsprechenden Stellung dargestellt. It can also be seen a safety unit constructed as a folding lever 13, which by a Axis of rotation 14 is rotatable. In the illustration shown in Figure 1 is the Folding lever 13 shown in a position corresponding to the functional state.

Das Arretiermittel 12 drückt in der in Figur 1 gezeigten Darstellung so auf den Kopf des Klapphebels 13, dass dieser in der dem Funktionszustand entsprechenden Stellung verbleibt. In dieser Stellung weist der Klapphebel 13 einen gewissen Abstand zu der Seitenwand 2 der Führungsschiene auf. Indem also dieses Arretiermittel 12 den Klapphebel 13 in der dem Funktionszustand entsprechenden Stellung festklemmt, ist das Sicherungsblockademittel 1 auch dann in der Führungsschiene beweglich, wenn das Führungsseil 7 noch nicht eingehängt ist bzw. keine mechanische Vorspannung aufweist. Die Bewegung des Aufnahmemittels 8 nach unten wird durch das Arretiermittel 12 begrenzt.The locking means 12 presses in the illustration shown in Figure 1 on the head of the Folding lever 13 that this remains in the position corresponding to the functional state. In this position, the folding lever 13 has a certain distance from the side wall 2 of the Guide rail on. So by this locking means 12, the folding lever 13 in the Functional state clamps the appropriate position, the fuse blocking means 1 also movable in the guide rail when the guide rope 7 is not yet hooked in is or has no mechanical preload. The movement of the receiving means 8 is limited by the locking means 12.

Wird nach erfolgter Montage das Arretiermittel 12 entfernt, indem die Schraube heraus gedreht wird, kann dann das Aufnahmemittel 8 ein Drehmoment auf den Kopf des Klapphebels 13 ausüben, wenn das Aufnahmemittel 8 infolge der Kraft der Feder 9 nach unten gedrückt wird. Dies ist dann der Fall, wenn das Führungsseil 7 abreißt oder seine mechanische Vorspannung verliert, die die Feder 9 zusammen gedrückt hält.After assembly, the locking means 12 is removed by removing the screw is rotated, the receiving means 8 can then apply a torque to the head of the Exercise folding lever 13 when the receiving means 8 due to the force of the spring 9 after is pressed down. This is the case when the guide rope 7 breaks or his loses mechanical bias, which keeps the spring 9 pressed together.

Durch dieses Drehmoment wird der Klapphebel 13 um die Drehachse 14 nach außengedreht, so dass der Klapphebel 13 an der Seitenwand 2 der Führungsschiene anliegt. Dadurch kann eine solche Reibungskraft aufgebaut werden, dass das Sicherungsblockademittel und damit auch das mit dem Sicherungsblockademittel verbundene Deckenlauftor zum Stehen kommt. Zum Aufbau einer entsprechenden Reibungskraft kann der Klapphebel 13 aus einem entsprechenden Material bestehen oder beschichtet sein. Dieses Material kann beispielsweise Gummi sein. Es ist aber auch möglich, die Seitenwand 2 so auszubilden, dass der Klapphebel 13 in definierten Stellungen in der Seitenwand 2 einrastet, wenn der Klapphebel 13 nach außen geklappt ist. Das Deckenlauftor kommt dann zum Stehen, wenn der Klapphebel 13 bei der Abwärtsbewegung des Deckenlauftores die nächste definierte Raststellung erreicht.This torque causes the folding lever 13 to be rotated outward about the axis of rotation 14, so that the folding lever 13 rests on the side wall 2 of the guide rail. This can such a frictional force can be built up that the fuse blocking means and thus the overhead door connected to the safety blocking means also comes to a standstill. To build up a corresponding frictional force, the folding lever 13 can be made from a appropriate material or be coated. This material can, for example Be rubber. But it is also possible to design the side wall 2 so that the folding lever 13 engages in defined positions in the side wall 2 when the folding lever 13 after is folded on the outside. The overhead door comes to a standstill when the folding lever 13 is at the downward movement of the overhead door reaches the next defined stop position.

In der in Figur 1 gezeigten Darstellung tritt der Klapphebel 13 aus einer seitlichen Öffnung aus dem Sicherungsblockademittel 1 aus. Es ist auch möglich, den Klapphebel 13 so anzubringen, dass dieser an der Unterseite des Sicherungsblockademittels 1 austritt.In the illustration shown in Figure 1, the folding lever 13 emerges from a side opening from the security blocking means 1. It is also possible to use the folding lever 13 in this way to ensure that it emerges from the underside of the fuse block means 1.

In Abweichung der Darstellung der Figur 1 kann anstelle des Klapphebels 13 auch eine anders ausgestaltete Sicherungseinheit verwendet werden. Beispielsweise kann zwischen der Unterseite des Aufnahmeteils 8 und einem unteren Abschluss des Sicherungsblockademittels eine gummiartige elastische Masse befestigbar sein. Wird dann das Aufnahmeteil bei abgerissenem Führungsseil infolge der Federkraft 9 nach unten gedrückt, dehnt sich diese Masse seitlich aus und klemmt das Sicherungsblockademittel 1 in der Führungsschiene fest.In a deviation from the illustration in FIG. 1, one can also be used instead of the folding lever 13 differently designed fuse unit can be used. For example, between the Bottom of the receiving part 8 and a lower end of the fuse block means a rubber-like elastic mass can be attached. Then the receiving part at torn guide rope pressed down due to the spring force 9, this expands Mass from the side and clamps the locking device 1 in the guide rail.

Figur 2 zeigt ein Ausführungsbeispiel eines Sicherungsblockademittels 1 in Kombination mit einem Führungsseil 7, das mit einer mechanischen Vorspannung beaufschlagt wird. Gleiche Teile wie bei Figur 1 sind dabei mit den gleichen Bezugszeichen versehen.Figure 2 shows an embodiment of a security blocking device 1 in combination with a guide rope 7, which is subjected to a mechanical pretension. Same Parts as in Figure 1 are provided with the same reference numerals.

Figur 2 ist zu entnehmen, dass das Führungsseil 7 im weiteren Verlauf über Umlenkrollen läuft. Die Umlenkrolle 201 wird im oberen Bereich des Deckenlauftores montiert. Es sind dabei die entsprechenden Montagemittel 202 zu sehen. Weiterhin wird das Führungsseil 7 an seinem oberen Ende 203 ortsfest angebracht. Das Führungsseil 7 läuft dann noch über eine Umlenkrolle 204, die nach Art eines Flaschenzuges mittels mehrerer paralleler Federn 205 im Bodenbereich ortsfest angebracht ist.FIG. 2 shows that the guide rope 7 continues over deflection pulleys running. The deflection roller 201 is mounted in the upper area of the overhead door. There are to see the corresponding assembly means 202. Furthermore, the guide rope 7 on fixed at its upper end 203. The guide rope 7 then runs over a Deflection roller 204, which in the manner of a pulley by means of several parallel springs 205 in Floor area is fixed.

Diese Federn 205 sind dabei so vorgespannt, dass das Führungsseil 7 immer unter einer solchen Vorspannung steht, dass die Feder 9 des Sicherungsblockademittels 1 zusammengedrückt wird, wenn das Führungsseil 7 in das Aufnahmemittel 8 eingehängt ist. Da diese Federkräfte der Federn 205 am geringsten sind, wenn sich das Deckenlauftor in seiner obersten Stellung befindet, müssen diese Federn so vorgespannt sein, dass die Federkraft der Federn 205 auch in dieser Stellung so groß ist, dass die Feder 9 des Sicherungsblockademittels 1 zusammen gedrückt wird.These springs 205 are biased so that the guide rope 7 is always under one such bias is that the spring 9 of the fuse block 1 is compressed when the guide rope 7 is suspended in the receiving means 8. Since these spring forces of the springs 205 are lowest when the overhead door is in in its uppermost position, these springs must be biased so that the Spring force of the springs 205 is so great in this position that the spring 9 of the Fuse blocking device 1 is pressed together.

Vorteilhaft sind mehrere Federn 205 parallel angebracht, so dass noch verbleibende Federkräfte vorhanden sind, wenn eine der Federn brechen sollte. Weiterhin sind in Figur 2 noch einige weitere Montagemittel dargestellt wie eine Abdeckung 206 für die Federn 205, sowie Laufrollen 207, die an dem Panzer des Deckenlauftores anbringbar sind, so dass dieser Panzer in der Laufschiene bewegbar ist.A plurality of springs 205 are advantageously attached in parallel, so that there are still springs Spring forces are present when one of the springs should break. Furthermore, in FIG. 2 some other assembly means are shown, such as a cover 206 for the springs 205, and casters 207, which can be attached to the armor of the overhead door, so that this Tanks in the running rail is movable.
