Abstract

Twisted stirrup for connecting or sealing elements is of V-shaped configuration, the lower region of each of the two legs (1, 2) forming an elongated loop (4, 5) with sealing means (6, 7) which consist of the closed end (6) of the narrower loop (4) on the one hand and of a sealing piece (7), which points into the interior of the broader loop (5) and lies in the same plane as the loop, on the other hand. The stirrup has a shoulder (10) on both sides of the point of transition (9) between the two legs (1, 2). By means of a device, the stirrup is laid around the elements to be connected or around the opening to be sealed, whereupon the sealing means (6, 7) are brought into engagement with one another by the device, and the stirrup is grasped and twisted in the region of the point of transition (9) by a connecting hook of the device. The loops (4, 5), when seen in their plane, are outwardly curved and the closed end piece (6) possesses a thinned portion (8) and is bent towards the other loop (5). Such a stirrup guarantees reliable functioning of the device for connecting. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen ver­drillbaren Drahtbügel zum Verbinden oder Verschliessen von Gegenständen gemäss dem Oberbegriff von Patentan­spruch 1. Ein solcher Drahtbügel ist der WO-87-01753 des gleichen Anmelders zu entnehmen, wobei dieser Drahtbügel einer von vielen Ausführungsbeispielen ist, die in die­ser Anmeldung offenbart sind.The present invention relates to a twistable wire bracket for connecting or closing objects according to the preamble of claim 1. Such a wire bracket can be found in WO-87-01753 by the same applicant, this wire bracket being one of many exemplary embodiments which are described in this Registration are disclosed.

Solche Drahtbügel werden für ein Verfahren und eine Vor­richtung zum Verbinden von mindestens zwei Stäben ver­wendet, wobei die Vorrichtung die Drahtbügel derart um die zu verbindenden Stäbe bringt, dass die Verschluss­mittel der Drahtbügel vom Greifmittel aus gesehen hinter den Stäben miteinander in Eingriff gebracht werden und der geschlossene Drahtbügel vor den Stäben vom Greifmit­tel des Bindegerätes erfasst und verdrillt wird. Bei ei­nem solchen Verfahren und Vorrichtung ist es wichtig, dass die Drahtbügel einzeln erfasst, sowie ohne zu klem­men ihre Aufgabe erfüllen können. Eingehende Versuche haben nun gezeigt, dass von den verschiedenen, in dieser Veröffentlichung offenbarten Drahtbügeln der eingangs erwähnte Drahtbügel für das ins Auge gefasste Verfahren gut geeignet ist. Um eine gute Handhabung und ein mög­lichst rationelles Laden der Vorrichtung zu gewährlei­sten, werden eine Anzahl von Bügel miteinander verklebt, wobei eine solche Einheit in die Vorrichtung geladen werden kann.Such wire clips are used for a method and a device for connecting at least two rods, the device bringing the wire clips around the bars to be connected in such a way that the closure means of the wire clips, viewed from the gripping means, are brought into engagement behind the bars and the closed one Wire bracket in front of the bars is gripped and twisted by the gripping device of the binding device. With such a method and device, it is important that the wire brackets are gripped individually and can perform their task without jamming. In-depth tests have now shown that of the various wire brackets disclosed in this publication, the wire bracket mentioned at the outset is well suited for the method envisaged. In order to ensure good handling and the most economical loading of the device, a number of brackets are glued together, and such a unit can be loaded into the device.

Eingehende Versuche haben nun gezeigt, dass es wün­schenswert ist, den Drahtbügel dahingehend zu verbes­sern, dass seine Vereinzelung und insbesondere sein si­cheres Verschliessen sowie das störungsfreie Funktionie­ren der Vorrichtung gewährleistet werden kann und es ist daher Aufgabe der vorliegenden Erfindung, einen solchen Drahtbügel anzugeben.In-depth tests have now shown that it is desirable to improve the wire hanger in such a way that it can be separated and in particular securely closed and the trouble-free functioning of the device can be guaranteed, and it is therefore an object of the present invention to provide such a wire hanger.

Die Aufgabe wird mit einem in den Ansprüchen definierten Drahtbügel gelöst.The task is solved with a wire bracket defined in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert.

  • Fig. 1 zeigt in perspektivischer Sicht den erfindungs­gemässen Drahtbügel,
  • Fig. 2 zeigt einige zu einer Einheit zusammengeklebte Drahtbügel gemäss Fig. 1,
  • Fig. 2A zeigt einen Drahtbügel aus Fig. 2 von links und
  • Fig. 2B zeigt einen Drahtbügel von Fig. 2 von rechts,
  • Fig. 3 zeigt eine Ausschnittsvergrösserung von Fig. 2A in einer anderen Sicht.
The invention is explained below with reference to a drawing of an embodiment.
  • 1 shows a perspective view of the wire bracket according to the invention,
  • 2 shows some wire clips according to FIG. 1 glued together to form a unit,
  • FIG. 2A shows a wire bracket from FIG. 2 from the left and
  • 2B shows a wire bracket of FIG. 2 from the right,
  • FIG. 3 shows an enlarged detail from FIG. 2A in a different view.

Der Drahtbügel gemäss Fig. 1 ist V-förmig ausgebildet und weist zwei Schenkel 1 und 2 auf, wobei der ganze Bü­gel aus einem einzigen Draht 3 besteht. Im unteren Be­reich, in vorliegendem Beispiel ab der Mitte, sind die beiden Schenkel 1 und 2 zu je einer länglichen Schlaufe 4 und 5 ausgebildet, wobei die eine Schlaufe 4 mit dem geschlossenen Ende 6 schmäler ist als die andere Schlau­fe 5 und in diese steckbar ist. Am unteren Ende der breiteren Schlaufe 5 befindet sich ein Verschlussstück 7, das in das Schlaufeninnere weist und in der gleichen Ebene wie die Schlaufe selbst liegt.1 is V-shaped and has two legs 1 and 2, the entire bracket consisting of a single wire 3. In the lower area, in the present example from the middle, the two legs 1 and 2 are each formed into an elongated loop 4 and 5, one loop 4 with the closed end 6 being narrower than the other loop 5 and being insertable into it . At the lower end of the wider loop 5 there is a closure piece 7 which points into the inside of the loop and lies in the same plane as the loop itself.

Aus Fig. 3 geht hervor, dass das geschlossene Ende 6 der Schlaufe 4 abgeflacht ist, d.h. eine Verdünnung 8 auf­weist, die ausserdem gegen die andere Schlaufe hin gebo­gen ist.From Fig. 3 it can be seen that the closed end 6 of the loop 4 is flattened, i.e. has a thinner 8, which is also bent towards the other loop.

Ausserdem geht aus den Figuren 2A und 2B hervor, dass die beiden Schlaufen 4 und 5, in ihrer Ebene gesehen, leicht nach aussen gewölbt sind.Furthermore, FIGS. 2A and 2B show that the two loops 4 and 5, seen in their plane, are slightly curved outwards.

Beim Uebergang 9 zwischen den beiden Schenkeln ist beid­seitig je ein Absatz 10 geformt, an welchem ein Schieber einer Vorrichtung zum Verbinden und Verdrillen angreift. Im Prinzip wäre es ausreichend, den Drahtbügel herzustel­len ohne die beiden Drahtteile miteinander zu verbin­den. Aus Sicherheitsgründen ist es jedoch vorteilhaft, die beiden Drahtteile mittels Schweissen punktweise mit­einander zu verbinden. In vorliegendem Ausführungsbei­spiel sind die beiden Drahtteile an vier Punkten ge­schweisst, nämlich bei Punkt 11 beim Verschlussstück 7, bei Punkt 12 an der Uebergangsstelle 9 sowie an den Punkten 13, wo sich die beiden Drahtteile zu den Schlau­fen 4 und 5 erweitern. Die Vorrichtung, für die die Drahtbügel gedacht sind, erfasst den Drahtbügel bei den Absätzen 10 und schiebt diesen durch zwei Backen der Vorrichtung, durch welche die Drahtbügel um die zu ver­bindenden Gegenstände oder um die Oeffnung eines zu ver­schliessenden Gegenstandes gelegt werden, wobei die schmälere Schlaufe 4 in die breitere Schlaufe 5 greift und das geschlossene Ende 6 das Verschlussstück 7 an der anderen Schlaufe hinterfasst. Bei den nachfolgenden Be­wegungen der Vorrichtung erfasst ein Bindehaken der Vor­richtung die Uebergangsstelle 9 des Drahtbügels und ver­drillt diesen.At the transition 9 between the two legs, a shoulder 10 is formed on both sides, on which a slide engages a device for connecting and twisting. In principle, it would be sufficient to produce the wire bracket without connecting the two wire parts together. For safety reasons, however, it is advantageous to connect the two wire parts to one another point by welding. In the present exemplary embodiment, the two wire parts are welded at four points, namely at point 11 at the closure piece 7, at point 12 at the transition point 9 and at points 13 where the two wire parts expand to form the loops 4 and 5. The device for which the wire brackets are intended grips the wire bracket at paragraphs 10 and pushes it through two jaws of the device, through which the wire brackets are placed around the objects to be connected or around the opening of an object to be closed, the narrower loop 4 engages in the wider loop 5 and the closed end 6 grips the closure piece 7 on the other loop. During the subsequent movements of the device, a binding hook of the device detects and twists the transition point 9 of the wire bracket.

Wie in Fig. 2 dargestellt, sind die Bügel mittels einem geeigneten Klebstoff zu einer Einheit verklebt, die in die dafür vorgesehene Vorrichtung eingelegt werden kann. Es kann auch ein anderes Klebemittel verwendet werden. Beim Verbinden oder Verschliessen müssen die Drahtbügel zuerst vereinzelt werden. Beim Schliessen der Drahtbügel muss eine gewisse Kraft aufgewendet werden, die möglichst gleichmässig auf die beiden Absätze 10 zu verteilen ist. Da infolge engerem Krümmungsradius und Dimensionen auf die schmälere Schlaufe eine grössere Kraft aufzuwenden ist, wurde durch das Abflachen und Ab­biegen ihres Endes erreicht, dass die aufzuwendenden Kräfte auf beide Schlaufen etwa gleich sind.As shown in Fig. 2, the brackets are glued to a unit using a suitable adhesive, which can be inserted into the device provided for this purpose. Another adhesive can also be used. When connecting or closing the wire clamps must be separated first. When closing the wire bracket, a certain force must be applied, which should be distributed as evenly as possible over the two shoulders 10. Because of the narrower radius of curvature and If a larger force is to be exerted on the narrower loop, by flattening and bending its end, the forces to be exerted on both loops are approximately the same.

Ausserdem müssen die Drahtbügel, respektive deren Schlaufen 4 und 5, in einem Kanal der Vorrichtung ge­führt werden, wobei es zweckmässig ist, wenn diese Schlaufen, und damit der ganze Drahtbügel, nicht ganz frei beweglich in den Kanälen der Vorrichtung laufen. Die leichte Bombierung der Schlaufen nach aussen hat zur Folge, dass die Drahtschlaufen eine leichte Federwirkung ausüben und somit in der Vorrichtung, nach der Vereinze­lung, festgehalten sind, wobei noch zusätzlich durch die Bombierung die Streuung in den Abmessungen durch die Fertigung aufgefangen werden.In addition, the wire brackets, or their loops 4 and 5, must be guided in a channel of the device, it being expedient if these loops, and thus the entire wire bracket, do not move freely in the channels of the device. The slight curvature of the loops to the outside means that the wire loops exert a slight spring effect and are thus retained in the device after the singulation, with the curvature additionally absorbing the dimensions in the manufacturing process.

Da die Drahtbügel nicht symmetrisch ausgebildet sind und daher nur in einer bestimmten Position in die Vorrich­tung eingeschoben werden sollen, sind die Einheiten mit­tels einer Markierung 14 auf einer Seite versehen.Since the wire clips are not symmetrical and should therefore only be inserted into the device in a certain position, the units are provided with a marking 14 on one side.

Obwohl der erfindungsgemässe verdrillbare Drahtbügel im Zusammenhang mit einer bestimmten Vorrichtung zum Ver­binden von zwei Gegenständen beschrieben wurde, kann der Drahtbügel auch in Vorrichtungen verwendet werden, die zwar nach dem gleichen Prinzip arbeiten, jedoch anders ausgebildet sind, insbesondere in Vorrichtungen zum Ver­schliessen von Säcken oder dergleichen anstatt zum Ver­binden von zwei Armierungseisenstäben, wie in der ein­gangs erwähnten Anmeldung offenbart.Although the twistable wire bracket according to the invention has been described in connection with a specific device for connecting two objects, the wire bracket can also be used in devices which work according to the same principle but are designed differently, in particular in devices for closing bags or the like instead of connecting two reinforcing iron bars as disclosed in the application mentioned at the beginning.
