Abstract

The restraining system for the pull cord (4) of a fire extinguisher, which activates the extinguisher when released, is a contracted structure (1) which is released by retainer (5,6) on being heated. The structure (1) is wound and twisted from a single spring steel wire, with an eyelet (2) at one end to take the extinguisher pull cord (4) and lead it through a further eyelet (3). The wire structure is held in the tensed restraining position by the retainer (5,6) to spring out when released and exert a pull on the extinguisher cord.

Description

Die Erfindung betrifft eine Zugseilverkürzung für Feuerlöschvorrichtungen nach dem Oberbegriff des Anspruches 1.The invention relates to a pull cord shortening for fire extinguishing devices according to the preamble of claim 1.

Derartige Zugseilverkürzungen sind beispielsweise bekannt, um die Zugseile für Küchenabzugshauben zu halten und zu sichern. Die Zugseile enden in einer Schalteinrichtung mit einem Absperrventil für das Löschmedium. Im Brandfall wird das thermische Auslöseelement - beispielsweise ein Glasfäßchen - der Trennvorrichtung zerstört, so daß sich das Zugseil bedingt durch die ausgeübte Zugspannung "verlängert", wodurch das Absperrventil geöffnet wird und das Löschmedium zu dem Brandherd gelangen kann.Such shortening of the pulling rope is known, for example, to hold and secure the pull ropes for kitchen hoods. The traction cables end in a switching device with one Shut-off valve for the extinguishing medium. In the event of a fire, it will thermal release element - for example a glass barrel - the separating device destroyed, so that the traction cable is conditional "extended" by the tension applied, whereby the shut-off valve is opened and the extinguishing medium to the The source of the fire can occur.

Bekannte Zugseilverkürzungen sind häufig so aufgebaut, daß das Zugseil zur Aufnahme des Verkürzungselementes durchgeschnitten werden muß. Es ist auch schon vorgeschlagen worden, das Verkürzungselement nach Art eines Scharniers so auszubilden, daß das Zugseil zur Führung und Umlenkung durch dieses Scharnier nicht mehr durchtrennt werden muß. Das Scharnier ist aber ein relativ aufwendiges und daher mit entsprechenden Kosten herzustellendes Bauteil.Known pull rope shortenings are often constructed in such a way that cut the pull rope to accommodate the shortening element must become. It has also been suggested the shortening element like a hinge train that the pull rope for guiding and deflecting this hinge no longer has to be cut. The But hinge is a relatively complex and therefore with corresponding component to be manufactured.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Zugseilverkürzung nach dem Oberbegriff des Anspruches 1 zu schaffen, die einfach aufgebaut ist und daher kostengünstig hergestellt werden kann. The invention is based on the object, a pull rope shortening to create according to the preamble of claim 1, which is simple and therefore inexpensive to manufacture can be.

Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelöst. Das Verkürzungselement besteht aus Federstahldraht, vorzugsweise einem einzigen Federstahldraht, der entsprechend gewickelt ist. Die Ösen sind so gewickelt und dimensioniert, daß das Zugseil ohne Schwierigkeiten und Unterbrechungen eingelegt werden kann. Dadurch daß es sich um Federdraht handelt, kann diese Federkraft ausgenutzt werden, um das Verkürzungselement selbst vorzuspannen.This object is achieved by the characterizing part of claim 1 solved. The shortening element consists of spring steel wire, preferably a single spring steel wire, the corresponding is wrapped. The eyelets are wound and dimensioned so that the pull rope without difficulty and interruptions can be inserted. Because it is spring wire acts, this spring force can be used to to preload the shortening element itself.

Gehalten wird das Verkürzungselement in der verkürzenden oder gespannten Stellung durch das thermisch auslösende Trennelement, wie es beispielsweise in der DE-OS 196 35 177 beschrieben ist. Diese dort vorgeschlagene Trennvorrichtung besteht aus zwei miteinander verbundenen Fügeteilen, die durch das thermische Auslöseelement, beispielsweise ein Glasfäßchen, in der Sicherungsstellung zusammengehalten werden. Wenn das thermische Auslöseelement zerstört wird, trennen sich die beiden Fügeteile und geben das Verkürzungselement frei, so daß sich dieses bedingt durch die Zugspannung in dem Zugseil und die Eigenspannung "verlängert", und zwar gegebenenfalls bis zu einem gradlinigen Verlauf des Zugseiles. Hierdurch wird auf jeden Fall erreicht, daß das Absperrventil geöffnet wird, so daß das Löschmedium durch entsprechende Leitungen zu den vorgesehenen Löschpunkten gelangt.The shortening element is kept in the shortening element or tensioned position due to the thermal release Separating element, as it is for example in DE-OS 196 35 177 is described. This separation device proposed there consists of two interconnected parts that through the thermal release element, for example a Glass vials are held together in the securing position. If the thermal trip element is destroyed, disconnect the two parts to be joined and give the shortening element free, so that this is due to the tension in the pull rope and the residual stress "extended", namely if necessary up to a straight line of the pull rope. This ensures that the shut-off valve is opened so that the extinguishing medium by appropriate Lines reach the designated deletion points.

In vorteilhafter Weise ist die Zugseilverkürzung so ausgebildet, wie in den Ansprüchen 3 und 4 unter Schutz gestellt.The shortening of the pulling rope is advantageously designed such that as protected in claims 3 and 4.

Fig. 7:
a side view of a guide bracket for a pull rope shortening according to the embodiment of FIGS. 1 to 4.

Das in den Fig. 1 bis 4 dargestellte Verkürzungselement 1 besteht aus einem Federdraht, der so gewickelt ist, daß zwei Endösen 2 und zwei Umlenkungsösen 3 entstehen.The shortening element 1 shown in FIGS. 1 to 4 consists of a spring wire that is wound so that two End eyelets 2 and two deflection eyelets 3 arise.

Das Zugseil 4 wird durch die Endösen 2 zu den Umlenkösen 3 geführt. Es geht ohne Unterbrechung durch. Es ist ohne weiteres erkennbar, daß die Umlenkung des Zugseiles 4 zu einer Verkürzung führt. Die Enden des Verkürzungselementes 1 bilden Haken in die die thermisch auslösende Trennvorrichtung 5 aus zwei Fügeteilen eingehängt ist. Die Fügeteile werden in der in Fig. 1 gezeigten Stellung durch ein thermisches Auslöseelement 6, in diesem Falle ein Glasfäßchen, zusammengehalten. Das Verkürzungselement 1 bildet selbst eine Feder, die die einzelnen Teile in Position hält und in Endsicherungsrichtung vorgespannt ist. Die Zugspannung im Zugseil 4 wirkt ebenso. The pull rope 4 is through the end eyelets 2 to the deflection eyelets 3rd guided. It goes on without a break. It is straightforward recognizable that the deflection of the pull rope 4 to a Shortening leads. Form the ends of the shortening element 1 Hooks into the thermal release device 5 is suspended from two parts to be joined. The parts to be joined are in the position shown in Fig. 1 by a thermal release element 6, in this case a glass barrel, held together. The shortening element 1 itself forms a spring, which holds the individual parts in position and in the final securing direction is biased. The tension in the pull rope 4 works as well.

Beim Betrachten der Fig. 2 wird deutlich, was im Falle der Zerstörung des thermischen Auslöseelementes, d.h. im Brandfalle, passiert. Durch die Zerstörung des thermischen Auslöseelementes 6 werden die Fügeteile der thermisch auslösenden Trennvorrichtung 5 freigegeben, so daß das Seil 4 nicht mehr so stark oder gar nicht umgelenkt wird, so daß es eine entsprechende Verlängerung erfährt. Hierdurch wird das nicht gezeigte Absperrventil geöffnet und der eigentliche Löschvorgang ausgelöst.Looking at Fig. 2 it becomes clear what in the case of Destruction of the thermal release element, i.e. in the event of fire, happens. By destroying the thermal release element 6 are the joining parts of the thermally triggering Disconnect device 5 released so that the rope 4 no longer is deflected as strongly or not at all, so that it is a corresponding one Undergoes extension. This will not Shut-off valve shown opened and the actual extinguishing process triggered.

In Verbindung mit Fig. 3 ist zu erkennen, daß das Zugseil 4 ohne Unterbrechung in die Ösen des Verkürzungselementes 1 eingelegt werden kann.In connection with Fig. 3 it can be seen that the pull rope 4th without interruption in the eyelets of the shortening element 1 can be inserted.

Die Ausführungsform nach Fig. 4 zeigt eine um 90° gedrehte thermisch auslösende Trennvorrichtung 5. Die Haken an den Enden des Verkürzungselementes 1 sind entsprechend anders gebogen.The embodiment according to FIG. 4 shows one rotated through 90 ° thermal release device 5. The hooks on the Ends of the shortening element 1 are correspondingly different bent.

Die Ausführungsform nach den Fig. 5 und 6 zeigt eine einfachere Geometrie. Das Verkürzungselement 11 ist nicht mehr ein Trapez, wie bei der Ausführungsform nach den Fig. 1 bis 4, sondern ein gleichschenkliges Dreieck. Es ist daher nur eine Umlenköse 11 vorhanden. Die Endösen sind mit 12 bezeichnet. Im übrigen wirkt dieses thermische Auslöseelement ebenso wie dasjenige nach den Fig. 1 und 2.The embodiment according to FIGS. 5 and 6 shows a simpler one Geometry. The shortening element 11 is no longer a trapezoid, as in the embodiment of FIGS. 1 to 4, but an isosceles triangle. It is therefore only a deflection eyelet 11 is present. The end loops are designated by 12. Otherwise, this thermal release element acts as well as that according to FIGS. 1 and 2.

Die Umlenköse 11 kann auch doppelt gewickelt sein, wenn dieses zur Erzielung bestimmter geometrischer Verhältnisse oder einer bestimmten Federkennlinie gewünscht wird.The deflection eyelet 11 can also be wound twice, if this to achieve certain geometrical relationships or a certain spring characteristic is desired.

In Fig. 7 ist die Zugseilverkürzung nach den Fig. 1 bis 5 dargestellt, wie sie in einem Führungsbügel 15 positioniert ist. Das Zugseil 4 ist mit Hilfe von Verbindungsmuffen 13 mit dem Zugseil einer Küchenabzugshaubeneinrichtung verbunden. Der Führungsbügel 15 weist einen U-förmigen Querschnitt auf, so daß das Verkürzungselement 1 in der Stellung gehalten wird, in der es dargestellt ist. Eine Drehbewegung um die Achse des Zugseiles ist nicht möglich.7 is the shortening of the pull cable according to FIGS. 1 to 5 shown as positioned in a guide bracket 15 is. The pull rope 4 is by means of connecting sleeves 13 connected to the pull rope of a kitchen hood device. The guide bracket 15 has a U-shaped cross section on, so that the shortening element 1 is held in position in which it is shown. A rotation around the axis of the pull rope is not possible.
