Description

Die Erfindung betrifft eine Sicherungsvorrichtung und einen Zargenholm für ein längs einer vorgegebenen Bahn zwischen einer vorzugsweise über Kopf angeordneten Öffnungsstellung und einer Schließstellung bewegbares Torblatt nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a securing device and a Zargenholm for a along a predetermined path between a preferably arranged above the head opening position and a closed position movable door leaf according to the preamble of patent claim 1.

Derartige Sicherungsvorrichtungen werden beispielsweise für Kipp- oder Sektionaltore benötigt, bei denen das Torblatt in der Schließstellung etwa in einer Vertikalebene angeordnet ist und mit Hilfe eines an dem Torblatt befestigten Zugmittels, wie etwa eines Zugseils oder einer Zugkette, in die über Kopf angeordnete Öffnungsstellung bewegt werden kann. Bei derartigen Toren muss verhindert werden, dass das Torblatt bei Bruch des Zugmittels nach unten abstürzt, weil andernfalls Benutzer des Tores verletzt oder Gegenstände im Bereich der mit dem Tor zu verschließenden Wandöffnung beschädigt werden können. Eine Sicherungsvorrichtung der eingangs beschriebenen Art, mit der das Abstürzen des Torblattes bei Bruch des Zugmittels verhindert werden kann, ist beispielsweise in der DE 34 27 105 C2 beschrieben. Bei der in dieser Schrift beschriebenen Sicherungsvorrichtung ist ein Fanggliedgehäuse verschiebbar an dem Torblatt gelagert. Bei Bruch des Zugmittels wird das Fanggliedgehäuse mit einer Vorspanneinrichtung verschoben. Im Verlauf dieser Verschiebung wird ein verschwenkbar in dem Fanggliedgehäuse gelagertes Fangglied mit einem an dem Torblatt festgelegten Bolzen in eine Sicherungsstellung verstellt, in der es an einer parallel zur Bewegungsrichtung des Verschlussblattes verlaufenden Fangschiene formschlüssig angreift, um so den Absturz des Torblattes zu verhindern.Such safety devices are required, for example, for tilting or sectional doors, in which the door leaf is arranged in the closed position approximately in a vertical plane and are moved by means of a fixed to the door leaf traction means, such as a pull rope or a pull chain in the overhead opening position can. In such gates, it must be prevented that the door leaf crashes when breakage of the traction device down, otherwise injured users of the door or objects can be damaged in the area to be closed with the gate wall opening. A safety device of the type described above, with the crash of the door leaf can be prevented at break of the traction means, for example, in the DE 34 27 105 C2 described. In the safety device described in this document, a catch member housing is slidably mounted on the door leaf. At break of Traction means the catcher housing is moved with a biasing device. In the course of this displacement, a catch member mounted pivotably in the catch member housing is adjusted with a bolt fixed to the door leaf into a securing position in which it positively engages a catch rail extending parallel to the direction of movement of the closure sheet so as to prevent the door leaf from falling.

Wenngleich mit der bekannten Sicherungsvorrichtung eine zuverlässige Sicherung des Torblattes erreicht werden kann, hat es sich gezeigt, dass die Konstruktion der bekannten Sicherungsvorrichtung vergleichsweise aufwendig gestaltet werden muss, weil die gesamte Gewichtskraft des Torblattes über das das Fangglied enthaltende Fanggliedgehäuse aufgenommen werden muss, so dass dieses Gehäuse entsprechend abzustützen und massiv auszuführen ist. Das hat insgesamt zur Folge, dass die bekannten Sicherungsvorrichtungen verhältnismäßig lang bauen.Although a reliable securing of the door leaf can be achieved with the known securing device, it has been found that the construction of the known securing device must be comparatively complicated, because the entire weight of the door leaf on the catch member containing catcher housing must be taken, so this Support housing accordingly and is massive perform. This has the overall result that the known security devices build relatively long.

Ferner hat es sich beim Einsatz der aus der DE 34 27 105 C2 bekannten Sicherungsvorrichtung als problematisch erwiesen, dass diese zwar eine zufriedenstellende Sicherung bei einem Bruch des Zugmittels bieten, jedoch keinerlei Einbruchssicherung zur Verfügung stellen. Daher können die mit den bekannten Sicherungsvorrichtungen ausgestatteten Tore mit Hilfe eines einfachen, in der Schließstellung an den unteren Rand des Torblattes angesetzten Hebels geöffnet werden.Furthermore, it has the use of the from the DE 34 27 105 C2 known backup device proved to be problematic, that while they provide a satisfactory backup at a fraction of the traction means, however, provide no burglary protection available. Therefore, equipped with the known security devices gates can be opened using a simple, in the closed position attached to the lower edge of the door leaf lever.

Dieser Mangel kann durch Bereitstellung einer in der DE 44 28 034 C1 beschriebenen Sperrklinkeneinrichtung beseitigt werden, bei der eine Sperrklinke bei Entlastung des Zugmittels in eine im Bereich eines der Zargenholme des Tores vorgesehene Eingriffsausbildung eingreift, um so eine Öffnungsbewegung des Torblattes zu verhindern. Allerdings ist die zusätzliche Bereitstellung der in der DE 44 28 034 C1 beschriebenen Sperrklinkeneinrichtung bei den in der DE 34 27 105 C2 beschriebenen Toren problematisch, weil sowohl die bekannte Sperrklinkeneinrichtung als auch das Fanggehäuse der aus der DE 34 27 105 C2 bekannten Sicherungsvorrichtung im Bereich des in der Schließstellung unteren Randes des Torblattes angebracht werden müssen, wobei beide Elemente auch noch im Bereich der seitlichen Zargenholme des Tores an dem Torblatt zu befestigen sind. Das bereitet im Besonderen im Hinblick auf die vorstehend erläuterte verhältnismäßig groß bauende Konstruktion des Fanggliedgehäuses der bekannten Sicherungsvorrichtung Probleme.This deficiency can be achieved by providing one in the DE 44 28 034 C1 described pawl device are eliminated, in which a pawl engages in relief of the traction means in a provided in the region of one of the Zargenholme of the door engagement training, so as to prevent an opening movement of the door leaf. However, the additional provision is in the DE 44 28 034 C1 described pawl device in the in the DE 34 27 105 C2 described gates problematic, because both the known pawl device and the catch housing of the DE 34 27 105 C2 known securing device in the region of the closed position in the lower edge of the door leaf must be mounted, both elements are still to be attached to the door leaf in the region of the lateral frame spars of the door. This causes in particular in view of the above-described relatively large construction construction of the catch housing of the known safety device problems.

Ferner sind Sicherungsvorrichtungen der im Oberbegriff des Patentanspruchs 1 angegebenen Art aus der CA 1 108 198 A bekannt.Furthermore, securing devices are specified in the preamble of claim 1 type of the CA 1 108 198 A known.

Angesichts der vorstehend erläuterten Probleme im Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Sicherungsvorrichtung der eingangs beschriebenen Art bereitzustellen, die einerseits eine wirksame Einbruchssicherung ermöglicht und andererseits konstruktiv besonders einfach ausgeführt werden kann.In view of the above-described problems in the prior art, the present invention seeks to provide a safety device of the type described above, on the one hand enables effective burglar alarm and on the other hand structurally particularly simple.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebene Weiterbildung der bekannten Sicherungsvorrichtung gelöst.This object is achieved by the specified in the characterizing part of claim 1 development of the known safety device.

Diese Erfindung beruht auf der verblüffend einfachen Erkenntnis, dass die vorstehend erläuterten Probleme im Stand der Technik dadurch beseitigt werden können, dass ein und dasselbe Sicherungselement sowohl zum Verhindern des Abstürzens des Torblattes bei einem Bruch des Zugmittels als auch als Einbruchssicherung verwendet wird. Dabei kann dieses Sicherungselement ggf. mit einem oder mehreren weiteren an Begrenzungswänden des mit dem Torblatt zu verschließenden Raumes befestigten Sicherungselement zusammenwirken, um die gewünschte Funktion sicherzustellen. Auf diese Weise wird erreicht, dass im Bereich des Torblattes selbst nur noch ein Sicherungselement als Fangsicherung und Einbruchssicherung bereitgestellt werden muss, wodurch sich erhebliche konstruktive Vereinfachungen ergeben. Allerdings ist auch im Rahmen dieser Erfindung an den Einsatz von Sicherungsvorrichtungen gedacht, bei dem im Bereich der beiden seitlichen Ränder des Torblattes zwei oder mehr Sicherungsvorrichtungen der vorstehend beschriebenen Art angebracht sind, von denen jede ein sowohl als Einbruchssicherung als auch als Fangsicherung wirkendes Sicherungselement aufweist.This invention is based on the surprisingly simple recognition that the above-described problems in the prior art can be eliminated by using one and the same securing element both for preventing the door leaf from falling when the traction device is broken and as a burglar alarm. In this case, this securing element can optionally cooperate with one or more further attached to boundary walls of the door leaf to be closed space securing element to ensure the desired function. In this way, it is achieved that in the area of the door leaf itself only a securing element must be provided as a safety catch and burglar alarm, resulting in considerable structural simplifications. However, it is also intended in the context of this invention to the use of securing devices, in which two or more securing devices of the type described above are mounted in the region of the two lateral edges of the door leaf, each of which has a both acting as a burglar alarm and as a safety catch fuse element.

Das mit der beanspruchten Doppelfunktion ausgestattete Sicherungselement kann konstruktiv besonders einfach ausgeführt werden, wenn es ein erstes, vorzugsweise in Form einer in der Sicherungsstellung nach unten ragenden Sperrklinke gebildetes Sicherungssegment und ein zweites, vorzugsweise in Form einer in der Sicherungsstellung nach oben ragenden Sperrklinke gebildetes Sicherungssegment aufweist. Erfindungsgemäß ist mindestens ein weiteres Sicherungselement im Bereich des ersten Abschnittes der vorgegebenen Bahn an einer einen mit dem Torblatt zu verschließenden Raum begrenzenden Wand befestigt, das ein Widerlager für das erste Sicherungssegment aufweist. Dieses Widerlager ist bei der erfindungsgemäßen Sicherungsvorrichtung besonders einfach in Form einer oben offenen Ausbuchtung gebildet. Diese oben offene Ausbuchtung ist unter Vermeidung weiterer Bauteile in einem seitlichen Zargenholm des mit der erfindungsgemäßen Sicherungsvorrichtung ausgestatteten Tores vorgesehen.The equipped with the claimed double function fuse element can be structurally particularly simple, if it has a first, preferably in the form of a locking position in the downwardly projecting pawl formed securing segment and a second, preferably in the form of a securing position in the upwardly projecting pawl formed securing segment , According to the invention, at least one further securing element is fastened in the region of the first section of the predetermined path to a wall delimiting a space to be closed by the door leaf, which wall has an abutment for the first securing segment. This abutment is particularly simple in shape in the securing device according to the invention formed an open-topped bulge. This bulge, which is open at the top, is provided while avoiding further components in a lateral frame member of the door equipped with the safety device according to the invention.

Zum Erhalt einer zuverlässigen und konstruktiv besonders einfachen Einbruchssicherung ist mindestens ein weiteres Sicherungselement im Bereich des zweiten Abschnittes der vorgegebenen Bahn an einer einen mit dem Torblatt zu verschließenden Raum begrenzenden Wand befestigt, das ein Widerlager für das zweite Sicherungselement aufweist. Auch dieses mit dem zweiten Sicherungssegment zusammenwirkende Widerlager kann unter Vermeidung zusätzlicher Bauteile in Form einer in diesem Fall nach unten offenen Ausbuchtung des seitlichen Zargenholms des Tores ausgeführt sein.In order to obtain a reliable and structurally particularly simple burglary protection, at least one further securing element in the region of the second section of the predetermined path is fastened to a wall defining a space to be closed by the door leaf, which wall has an abutment for the second securing element. Also, this cooperating with the second securing segment abutment can be performed while avoiding additional components in the form of a downwardly open bulge in this case, the lateral Zargenholms the door.

Das Sicherungselement der erfindungsgemäßen Sicherungsvorrichtung ist zweckmäßigerweise an dem Torblatt befestigt und vorzugsweise bezüglich einer senkrecht zur vorgegebenen Bahn verlaufenden Schwenkachse verschwenkbar an dem Torblatt gelagert, um so unter Vermeidung eines konstruktiv aufwendigen, verschiebbar an dem Torblatt gelagerten Fanggehäuses eine zuverlässige Sicherung bereitzustellen. Als besonders günstig hat es sich erwiesen, wenn das Sicherungselement nach Art eines Sicherungshebels gebildet ist, der an seinem einen axialen Ende die Sicherungssegmente aufweist und im Bereich seines anderen axialen Endes um eine vorzugsweise etwa senkrecht zu der vorgegebenen Bahn und parallel zur Torblattebene verlaufende Schwenkachse verschwenkbar gelagert ist.The securing element of the securing device according to the invention is advantageously attached to the door leaf and preferably mounted pivotally relative to a perpendicular to the predetermined path pivot axis on the door leaf, so as to provide a reliable backup while avoiding a structurally complex, slidably mounted on the door leaf catching housing. To be particularly favorable, it has been found that the securing element is formed in the manner of a safety lever, which has the securing segments at one axial end and in the region of its other axial end about a preferably approximately perpendicular to the predetermined path and parallel to the door leaf plane pivoting pivot axis is stored.

Das erfindungsgemäß mit einer Doppelfunktion ausgestattete Sicherungselement der erfindungsgemäßen Vorrichtung kann bei einer besonders bevorzugten Ausführungsform der Erfindung auch noch eine dritte Funktion übernehmen, mit der es eine Abschaltung einer Antriebseinrichtung für das Torblatt bewirkt, wenn das Sicherungselement in die Sicherungsstellung verstellt wird. Zu diesem Zweck ist das Sicherungselement vorzugsweise im Bereich des verschwenkbar an dem Torblatt gelagerten axialen Endes mit einem Steuernocken zur Betätigung eines Schalters der Antriebseinrichtung für das Torblatt bei einer Verstellung des Sicherungselementes von der Freigabestellung in die Sicherungsstellung ausgestattet.The inventively equipped with a dual function fuse element of the device according to the invention can also take a third function in a particularly preferred embodiment of the invention, with which it causes a shutdown of a drive device for the door leaf, when the fuse element is moved to the securing position. For this purpose, the securing element is preferably provided in the region of the pivotally mounted on the door leaf axial end with a control cam for actuating a switch of the drive device for the door leaf during an adjustment of the securing element from the release position to the securing position.

Mit der erfindungsgemäßen Vorrichtung kann eine besonders zuverlässige Sicherung erreicht werden, wenn eine das Sicherungselement in die Sicherungsstellung drängende Vorspanneinrichtung, wie etwa eine Torsionsfeder vorgesehen ist. Dabei kann das Sicherungselement zur Ermöglichung einer Torblattbewegung in der Freigabestellung gehalten werden, wenn es an ein Zugmittel gekoppelt, vorzugsweise direkt damit verbunden ist, mit dem es bei einer Zugbelastung gegen die Vorspannkraft der Vorspanneinrichtung in die Freigabestellung gedrängt wird. In diesem Fall kann das Sicherungselement mit einer verhältnismäßig geringen Kraft in der Freigabestellung gehalten werden, wenn das Zugmittel an dem der Schwenkachse abgewandten Ende des Sicherungselementes befestigt ist.With the device according to the invention, a particularly reliable backup can be achieved if an urging the fuse element in the securing position Biasing means, such as a torsion spring is provided. In this case, the securing element can be kept in the release position for enabling a Torblattbewegung when it is coupled to a traction means, preferably directly connected thereto, with which it is urged in a tensile load against the biasing force of the biasing device in the release position. In this case, the securing element can be held with a relatively small force in the release position when the traction means is fixed to the pivot axis remote from the end of the securing element.

Bei einem mit einer erfindungsgemäßen Sicherungsvorrichtung ausgestatteten Torblatt ist die Sicherungsvorrichtung zweckmäßigerweise im Bereich des in der Schließstellung unteren Randes des Torblattes befestigt. Ein unter Verwendung eines derartigen Torblattes hergestelltes Tor umfasst bei einer besonders vorteilhaften Ausführungsform der Erfindung seitliche Zargenholme, in denen die vorstehend erläuterten weiteren Sicherungselemente vorgesehen sind.In a door leaf equipped with a security device according to the invention, the securing device is expediently fastened in the region of the lower edge of the door leaf in the closed position. In a particularly advantageous embodiment of the invention, a door produced using such a door leaf comprises lateral frame members in which the further securing elements explained above are provided.

Das Sicherungselement 40 weist eine Öffnung auf, in der der Bolzen 36 aufgenommen ist. An dem dem Verbindungsbereich 46 benachbarten Ende weist das nach Art eines Sicherungshebels gebildete Sicherungselement 40 eine erste nach unten ragende Sperrklinke 42 sowie eine zweite nach oben ragende Sperrklinke 44 auf.The securing device 30 comprises a housing 32 as well as a securing element 40, which is accommodated in the housing 32 and is pivotable on a bolt 36 which is pivotable with its bolt axis parallel to the door leaf and perpendicular to the direction of movement of the door leaf and which is pivotally mounted on its end facing away from the bolt 36 via a connecting region 46 is connected to the pull chain 12. The securing element 40 has an opening in which the bolt 36 is received. At the end adjacent to the connecting region 46, the securing element 40 formed in the manner of a securing lever has a first downwardly projecting pawl 42 and a second upwardly projecting pawl 44.

Dem Sicherungselement 40 ist eine Torsionsfeder 50 zugeordnet, mit dem es in Richtung auf die Wand 5 gedrängt wird. Dazu stützt sich ein Ende 52 der Torsionsfeder 50 an dem Gehäuse 32 ab, während sich das andere Ende 54 der Torsionsfeder 50 an dem Sicherungselement 40 abstützt, um so das Sicherungselement 40 aus der in Fig. 1 dargestellten Freigabestellung in der durch den Pfeil B angedeuteten Richtung in die in Fig. 2 dargestellte Sicherungsstellung zu drängen. Das Gehäuse 32 ist im Bereich seiner der Wand 5 zugewandten Begrenzung mit einer Öffnung 34 versehen, durch die das Sicherungselement 40 hindurchtreten kann. Durch eine Zugbeanspruchung der Zugkette 12 wird das über den Befestigungsbereich 46 damit verbundene Sicherungselement in der in Fig. 1 dargestellten Freigabestellung gehalten. Falls die Zugkette 12 bricht, entfällt die das Sicherungselement 40 beaufschlagende Zugspannung, so dass dieses Sicherungselement 40 unter der Wirkung der Torsionsfeder 50 durch die Öffnung 34 in die in Fig. 2 dargestellte Sicherungsstellung gelangt. In dieser Sicherungsstellung greift die Sperrklinke 42 in eine der im oberen Bereich des seitlichen Zargenholms 20 vorgesehenen, nach oben offenen Ausbuchtungen 22 und verhindert so, dass das Torblatt 10 nach unten abstürzt.The securing element 40 is associated with a torsion spring 50, with which it is urged in the direction of the wall 5. For this purpose, one end 52 of the torsion spring 50 is supported on the housing 32, while the other end 54 of the torsion spring 50 is supported on the securing element 40, so as to secure the securing element 40 from the in Fig. 1 shown release position in the direction indicated by the arrow B direction in the in Fig. 2 to force shown securing position. The housing 32 is provided in the region of its wall 5 facing the boundary with an opening 34 through which the fuse element 40 can pass. Due to a tensile stress of the pull chain 12, the securing element connected thereto via the fastening region 46 in the in Fig. 1 held release position held. If the pull chain breaks 12, eliminates the securing element 40 acting tensile stress, so that this securing element 40 under the action of the torsion spring 50 through the opening 34 in the in Fig. 2 shown securing position arrives. In this securing position, the pawl 42 engages in one of the provided in the upper region of the side frame member 20, upwardly open bulges 22 and thus prevents the door leaf 10 crashes down.

In Fig. 3 ist das Sicherungselement 40 in seiner Funktion als Einbruchssicherung dargestellt. Falls das Torblatt 10 aus der in Fig. 3 dargestellten Schließstellung mit Hilfe eines am unteren Rand des Torblattes 10 angesetzten Hebels 17 nach oben bewegt werden soll, erfolgt ebenfalls eine Zugentlastung der Zugkette 12. Das gilt selbst dann, wenn die Zugkette 12 an eine Gewichtsausgleichseinrichtung in Form einer Torsionsfeder gekoppelt ist, sofern das Tor mit einem Wellenantrieb ausgestattet ist, der die Federwelle im geschlossenen Zustand des Tores blockiert. Aufgrund der Zugentlastung der Zugkette 12 bewirkt die Torsionsfeder 50 auch in diesem Fall eine Verstellung des Sicherungselementes 40 in die Sicherungsstellung, in der das mit den Sperrklinken 42 und 44 ausgestattete Ende des Sicherungselementes außerhalb des Gehäuses 32 freiliegt. Bei einer Öffnungsbewegung des Torblattes gelangt die zweite Sperrklinke 44 in Eingriff mit in Form von nach unten offenen Ausbuchtungen des seitlichen Zargenholms 20 gebildeten Widerlagern 24, um so eine Öffnungsbewegung des Torblattes zu blockieren.In Fig. 3 the fuse element 40 is shown in its function as a burglar alarm. If the door leaf 10 from the in Fig. 3 shown closed position with the help a lever at the bottom of the door leaf 10 is to be moved upward, also takes place a strain relief of the pull chain 12. This is true even if the pull chain 12 is coupled to a weight balancing device in the form of a torsion spring, if the door equipped with a shaft drive is that blocks the spring shaft in the closed state of the gate. Due to the strain relief of the pull chain 12 causes the torsion spring 50 in this case, an adjustment of the fuse element 40 in the securing position in which the equipped with the pawls 42 and 44 end of the fuse element outside the housing 32 is exposed. During an opening movement of the door leaf, the second pawl 44 engages in the form of downwardly open bulges of the side frame member 20 formed abutments 24, so as to block an opening movement of the door leaf.

Gemäß Fig. 2 und 3 erfüllt das Sicherungselement 40 der erfindungsgemäßen Vorrichtung zwei Funktionen, nämlich zum einen eine Sicherung des Torblattes bei Bruch des Zugmittels und zum anderen die Funktion einer Einbruchssicherung. Darüber hinaus wird bei der in der Zeichnung dargestellten Ausführungsform der Erfindung mit Hilfe des Sicherungselementes 40 bei einer Zugentlastung der Zugkette 12 auch noch ein zum Bewegen des Torblattes 10 zwischen der Öffnungsstellung und der Schließstellung ausgelegter motorischer Antrieb ausgeschaltet. Zu diesem Zweck ist das Sicherungselement 40 an seinem am Bolzen 36 festgelegten Ende mit einem Steuernocken 48 ausgestattet, welcher bei Verschwenken des Sicherungselementes in die Sicherungsstellung ein Betätigungselement 62 eines Schalters 60 verstellt, um so den motorischen Antrieb auszuschalten, wie besonders deutlich aus einer vergleichenden Betrachtung der Fig. 1 einerseits mit den Fig. 2 und 3 andererseits hervorgeht. Gleiches ist auch in Fig. 4 erkennbar.According to Fig. 2 and 3 meets the fuse element 40 of the device according to the invention two functions, namely on the one hand a backup of the door leaf in case of breakage of the traction means and on the other hand, the function of a burglar alarm. In addition, in the embodiment shown in the drawing of the invention with the aid of the securing element 40 at a strain relief of the pull chain 12 also turned off for moving the door leaf 10 between the open position and the closed position designed motor drive. For this purpose, the securing element 40 is provided at its end fixed to the bolt 36 with a control cam 48 which, upon pivoting of the securing element in the securing position an actuator 62 of a switch 60 adjusted so as to turn off the motor drive, as particularly clear from a comparative analysis of the Fig. 1 on the one hand with the Fig. 2 and 3 on the other hand. The same is true in Fig. 4 recognizable.

Wie aus Fig. 4 weiter hervorgeht, sind die als weitere Sicherungselemente dienenden Ausbuchtungen 22 und 24 so ausgeführt, dass die zweite Sperrklinke 24 bei einem Verschwenkwinkel α in Eingriff mit den Ausbuchtungen 24 gelangt, welcher geringer ist als ein Verschwenkwinkel β, der zum Eingreifen der ersten Sperrklinke 42 in die Ausbuchtung 22 benötigt wird. Daraus geht hervor, dass im Sinne dieser Beschreibung jede Stellung des Sicherungselementes als Sicherungsstellung anzusehen ist, in der ein Teil des Sicherungselementes 40 außerhalb des Gehäuses 32 freiliegt.How out Fig. 4 Further, as the further securing elements serving bulges 22 and 24 are designed so that the second pawl 24 at a Verschwenkwinkel α comes into engagement with the bulges 24, which is less than a pivot angle β, for engaging the first pawl 42 in the Bulge 22 is needed. It follows that for the purposes of this description, each position of the securing element is to be regarded as a securing position in which a part of the securing element 40 is exposed outside the housing 32.

Die Erfindung ist nicht auf das anhand der Beschreibung erläuterte Ausführungsbeispiel beschränkt. Vielmehr ist auch an solche Ausführungsformen gedacht, bei denen separate Widerlager an der Wand 5 festgelegt sind. Weiter können die Sperrklinken des Sicherungselementes der erfindungsgemäßen Vorrichtung auch eine andere Form aufweisen oder an anderen Stellen angeordnet sein. Ferner kann anstelle einer Zugkette auch ein Zugseil oder eine Kombination aus einem Zugseil und einer Zugkette eingesetzt werden, wobei die Zugkette an dem Torblatt festgelegt ist und in ein auf einer an der Federwelle festgelegten Wickeltrommel aufwickelbares Zugseil übergeht.The invention is not limited to the embodiment explained with reference to the description. Rather, is also intended to those embodiments in which separate Abutment on the wall 5 are fixed. Further, the pawls of the fuse element of the device according to the invention may also have a different shape or be arranged at other locations. Further, instead of a pull chain and a pull rope or a combination of a pull rope and a pull chain can be used, wherein the pull chain is fixed to the door leaf and merges into a on a fixed to the spring shaft winding drum pull rope.
