Definitions

  • the present invention relates to a method for connecting at least two rods, wherein a binding device provided with locking jaws brings a wire bracket extending around the rods, the limb ends of which have locking means, around the rods to be connected in such a way that the locking means, from the binding device seen behind the bars are engaged with each other, and on a binding device for performing this method with locking jaws which are designed to engage the locking means on the wire bracket below the bars to be connected, and on a wire bracket for performing this method, the V is bent in a shape and has closure means at the ends of the legs.

This means that two wire pieces with four welding points are required per work step, which makes their production complex and therefore relatively expensive.
  • This object is achieved with the method described in claims 1 and 2, the binding device described in claims 3 to 21 and the wire bracket described in claims 22 to 27.

Arranged around the housing and slidably there is the movable handle part 13, with which the foremost wire bracket is gripped from the magazine and moved forwards or downwards.

  • FIG. 7 shows how the wire bracket is in the end position and it can be seen that the loop is placed over the locking hook in such a way that the loop engages behind the hook during a retraction movement. It can also be seen from FIG. 7 that in the end position the wire bracket slides out on both sides of the channel formed by the lower U-shaped plate 21 and cam 37, since in this position the wire bracket has the thinnest point, seen from the side.
  • the description and Figures 1 to 7 show the following workflow: When pushing the binding device forward over a crossing point of two rods A, B to be connected, the binding device either hits the bottom C with the locking jaws or with the locking hook on the upper rod A on, and in the further forward movement the movable handle part 13 is pushed forward. As a result, the wire bracket, as shown in FIG. 3, is pushed into the closing jaws. At the same time, the locking jaws are closed, as a result of which the locking loop 5 is placed over the locking hook 4. When pulling back, the locking loop is first locked with the locking hook on the wire bracket and the entire binding device is pulled back.

Abstract

Process for connecting two rods in which a connecting piece provided with a rotary hook seizes a loop of wire surrounding the rods and twists it during a tractional movement, whereby the rods to be connected (A, B) are surrounded by a wire stirrup (61), the ends of which are provided with connecting pieces (96, 100), so that the connecting pieces when seen from the hook (16) side connect with one another behind the rods, and the closed stirrup is gripped in front of the rods by the hook (16) of the connecting piece (50) and is twisted. The connecting piece (50) comprises a slide (88) connected with a moveable engagement piece for advancing the stirrup (61a), and jaws (54, 55) which place the locking pieces (96, 100) of the stirrup behind the rods to be connected (A, B). With this device it is possible to connect in a single operation two reinforcing bars by a simple pressure forward and backwards so that one thus avoids the difficulty of pushing the connecting wire behind the rods which are to be connected. In particular this considerably simplifies working on the ground, enables the work to be performed by less skilled personnel and in addition is faster than conventional methods.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Verbinden von mindestens zwei Stäben, wobei ein mit Schliessbacken versehenes Bindegerät einen um die Stäbe reichenden Drahtbügel, dessen Schenkel-Enden Verschlussmittel aufweisen, derart um die zu verbindenden Stäbe bringt, dass die Verschlussmittel, vom Bindegerät aus gesehen, hinter den Stäben miteinander in Eingriff gebracht werden, und auf ein Bindegerät zur Durchführung dieses Verfahrens mit Schliessbacken die ausgebildet sind, die Verschlussmittel am Drahtbügel unterhalb der zu verbindenden Stäbe zum Eingriff zu bringen, sowie auf einen Drahtbügel zur Durchführung dieses Verfahrens, der V-förmig gebogen ist und an den Schenkel-Enden Verschlussmittel aufweist. Ein solches Verfahren und Vorrichtung wird im allgemeinen beim Befestigen von Armierungseisen bei der Herstellung von Stahlbeton-Bauwerken verwendet, wobei die Armierungseisen in der Regel orthogonal aufeinanderliegen und an ihren Kreuzungsstellen miteinander verbunden werden.The present invention relates to a method for connecting at least two rods, wherein a binding device provided with locking jaws brings a wire bracket extending around the rods, the limb ends of which have locking means, around the rods to be connected in such a way that the locking means, from the binding device seen behind the bars are engaged with each other, and on a binding device for performing this method with locking jaws which are designed to engage the locking means on the wire bracket below the bars to be connected, and on a wire bracket for performing this method, the V is bent in a shape and has closure means at the ends of the legs. Such a method and device is generally used for fastening reinforcing bars in the production of reinforced concrete structures, the reinforcing bars generally lying orthogonally on top of one another and being connected to one another at their crossing points.

Das obige Verfahren sowie das Bindegerät und der Drahtbügel sind aus der US-A-3 810 495 bekannt, worin mit einem angetriebenen Gerät ein steifer Drahtbügel um die zu verbindenden Stäbe gelegt wird, wobei ein Schenkel des Bügels eine Oeffnung aufweist, durch die der andere Schenkel geführt und festgeklemmt wird. Da die Bügel alleine durch ihre Steifigkeit halten, erfordert dies einen grossen Kraftaufwand, der zu einem mechanisch aufwendigen Gerät führt, das störanfällig und schwer und daher für den rauhen Betrieb auf einer Baustelle ungeeignet ist.The above method as well as the binding device and the wire bracket are known from US-A-3 810 495, in which a rigid wire bracket is placed around the rods to be connected with a driven device, one leg of the bracket having an opening through which the other Leg is guided and clamped. Since the stirrups hold by their rigidity alone, this requires a great deal of force, which leads to a mechanically complex device which is prone to failure and heavy and is therefore unsuitable for rough operation on a construction site.

Ausserdem sind ein Verfahren und Vorrichtung aus der DE-A-24 58 133 bekannt, worin ein Draht um die zu verbindenden Stäbe gelegt wird, die Enden des Drahtstükkes in das Drillgerät eingeführt und in einer Stossbewegung desselben miteinander verdrillt werden. Dabei muss der Draht mit der Hand um die Stäbe geschlungen werden, wobei es sich in den meisten Fällen um am Boden liegende Bewehrungseisen handelt. Daher muss sich der Arbeiter dabei tief bücken, und anschliessend genau zielen, um beide Drahtenden zu erfassen.In addition, a method and device are known from DE-A-24 58 133, in which a wire is placed around the rods to be connected, the ends of the wire piece are inserted into the drill and twisted together in a pushing movement thereof. The wire must be wrapped around the bars by hand, which in most cases is reinforcement bars lying on the ground. Therefore, the worker has to bend down deeply and then aim precisely in order to grasp both wire ends.

Es konnte sich daher bis jetzt noch keines dieser Geräte auf dem Markt durchsetzen, da sie in der Regel für den rauhen Betrieb auf einer Baustelle zu kompliziert oder störanfällig sind. Aus diesem Grunde herrscht immer noch ein einfaches Verfahren und Gerät vor, bei welchem es vorwiegend auf die Geschicklichkeit und Ausdauer des spezialisierten Arbeiters ankommt. Dabei werden vorgefertigte Drahtstücke verwendet, die an ihren beiden Enden Ringe oder Oesen aufweisen. Infolge der erwünschten Flexibilität und dadurch geringen Dicke des Drahtes, werden aus Sicherheitsgründen jeweils zwei dieser Drahtstücke von Hand um die zu verbindenden Stäbe gelegt und oben die vier Oesen durch eine Verdrillgerät erfasst, das aus einem Stab mit Haken besteht, wobei der Stab gerändelt ist und in einem entsprechenden Griff läuft, so dass beim Ziehen des Griffes der Stab und somit der Haken in Drehung versetzt wird. Dieses Verfahren und Gerät hat den Vorteil, einfach zu sein, wobei jedoch das aus nur zwei Teilen bestehende Gerät den wesentlichen Nachteil aufweist, dass die Drahtstücke unter die zu verbindenden Stäbe hindurchgesteckt werden müssen, so dass sich die ausführende Person tief bücken muss, falls, wie im allgemeinen, die Armierungen am Boden sind. Ausserdem müssen die Drahtstücke in einer Hand getragen werden, während mit der anderen Hand das Gerät bedient wird. Um möglichst viele Drahtstücke auf einmal erfassen zu können, dürfen die Verbindungsstellen an den Oesen nicht auftragen, und es war infolgedessen notwendig, die Oesen zu verschweissen anstatt zu verdrillen. Das bedeutet, pro Arbeitsgang werden zwei Drahtstücke mit vier Schweiss-Stellen benötigt, wodurch deren Herstellung aufwendig und daher relativ kostspielig wird.So far, none of these devices has been able to establish itself on the market because they are generally too complicated or prone to failure for rough operation on a construction site. For this reason, there is still a simple method and device in which the skill and endurance of the specialized worker are the most important factors. Prefabricated pieces of wire are used that have rings or eyelets at both ends. Due to the desired flexibility and therefore small thickness of the wire, two of these wire pieces are placed by hand around the rods to be connected for safety reasons and the four eyelets are grasped at the top by a twisting device consisting of a rod with a hook, the rod being knurled and runs in an appropriate handle so that when the handle is pulled, the rod and thus the hook are rotated. This method and device has the advantage of being simple, but the device consisting of only two parts has the significant disadvantage that the wire pieces have to be inserted under the rods to be connected, so that the person carrying out the work has to bend down deeply if as in general, the reinforcements are on the floor. In addition, the wire pieces must be carried in one hand while the device is operated with the other hand. In order to be able to grasp as many pieces of wire at once, the connection points must not be applied to the eyelets, and it was consequently necessary to weld the eyelets instead of twisting them. This means that two wire pieces with four welding points are required per work step, which makes their production complex and therefore relatively expensive.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung, ein Verfahren und ein Bindegerät zur Durchführung des Verfahrens anzugeben, womit die Verbindung von mindestens zwei Stäben für die Bedienungsperson einfacher und schneller durchgeführt werden kann, das Bindegerät möglichst leicht und handlich sowie dem rauhen Baustellenbetrieb gewachsen ist, und einen Verbindungs-Drahtbügel anzugeben, dessen Material- und Herstellungskosten bei erforderlicher Zuverlässigkeit geringer sind. Diese Aufgabe wird mit dem in den Ansprüchen 1 und 2 beschriebenen Verfahren, dem in den Ansprüchen 3 bis 21 beschriebenen Bindegerät und dem in den Ansprüchen 22 bis 27 beschriebenen Drahtbügel gelöst.In contrast, it is an object of the present invention to provide a method and a binding device for carrying out the method, with which the connection of at least two rods can be carried out more easily and quickly for the operator, the binding device is as light and handy as possible and can withstand the rough construction site operation, and specify a connecting wire bracket, the material and manufacturing costs are lower with reliability required. This object is achieved with the method described in claims 1 and 2, the binding device described in claims 3 to 21 and the wire bracket described in claims 22 to 27.

Anstatt zwei gesonderte Drahtschlaufen mit je zwei Oesen zu verwenden, wird bei dem erfindungsgemässen Verfahren ein Drahtbügel 1 (gemäss den Figuren 9-12) verwendet, der in sich geschlossen ist und, siehe Figur 9, von der Seite aus gesehen V-förmig ausgebildet ist. Die beiden Schenkel 2 und 3 weisen an ihren unteren Enden Verschlussmittel auf, die in vorliegendem Beispiel aus einem Haken 4 am Schenkel 2 und aus der Schlaufe 5 am anderen Schenkel 3 bestehen. Wie insbesondere aus Figur 10 hervorgeht, wird der Haken 4 von den beiden verschweissten Schenkel-Endteilen gebildet, wobei der Haken aus der Schenkel-Ebene herausgebogen ist. Wie aus den Figuren 9 - 12 und deren Beschreibung hervorgeht, wird auch hier der Einzeldraht 6 doppelt genommen, wodurch einerseits eine geeignete Flexibilität und andererseits eine ausreichende Zerreissfestigkeit erreicht werden kann. Jedoch wird der Draht nur an einer Stelle, beim Haken 4, verschweisst, wodurch die Herstellung eines Bügels für eine Verbindungsstelle vereinfacht wird. Die Uebergangsstelle 7 zwischen den beiden Schenkeln ist zuoberst gerundet und weist beidseitig einen Absatz 8 auf, dessen Bedeutung im Zusammenhang mit dem Bindegerät weiter unten erläutert wird. Der Drahtbügel kann aus einem geeigneten, bisher verwendeten Material hergestellt sein, wobei die üblichen Anforderungen an Verformbarkeit, Schweissfähigkeit und Zerreissfestigkeit erfüllt sein müssen.Instead of using two separate wire loops, each with two eyelets, a wire bracket 1 (according to FIGS. 9-12) is used in the method according to the invention, which is self-contained and, see FIG. 9, is V-shaped when viewed from the side . The two legs 2 and 3 have closure means at their lower ends, which in the present example consist of a hook 4 on the leg 2 and of the loop 5 on the other leg 3. As can be seen in particular from FIG. 10, the hook 4 is formed by the two welded leg end parts, the hook being bent out of the leg plane. As can be seen from FIGS. 9-12 and their description, the individual wire 6 is also taken twice here, which means that suitable flexibility and sufficient tensile strength can be achieved on the one hand. However, the wire is only welded at one point, at the hook 4, which simplifies the manufacture of a bracket for a connection point. The transition point 7 between the two legs is rounded at the top and has a shoulder 8 on both sides, the meaning of which is explained below in connection with the binding device. The wire bracket can be made from a suitable material previously used, whereby the usual requirements for deformability, weldability and tensile strength must be met.

Im Gegensatz zu den meisten bekannten Verfahren wird nun der Drahtbügel, wie in Figur 9 dargestellt, von oben über die zu verbindenden Eisen gebracht, siehe auch Figur 1. Anschliessend werden die unteren Enden der beiden Schenkel durch die Verschlussmittel 4 und 5 miteinander verbunden, wonach der Haken des Bindegerätes die Uebergangsstelle 7 des Drahtbügels erfasst und den oberen Teil des Bügels verdrillt. Dadurch, dass das Verbinden von oben her erfolgt und der Drahtbügel nicht mehr von Hand unter die Eisen hindurchgeschoben werden muss, wird die Arbeit wesentlich erleichtert, da sich die bedienende Person nicht mehr so tief bücken muss. Im folgeden werden zwei Ausführungsbeispiele eines Bindegerätes beschrieben, mit welchem es möglich ist, die Verschlussmittel des Drahtbügels in Eingriff zu bringen, ohne dass die bedienende Person die Drahtbügel in die Hand nehmen muss, so dass das Verbinden durch einen einzigen Bewegungsablauf des Bindegerätes erfolgt.In contrast to most of the known methods, the wire bracket, as shown in FIG. 9, is now brought from above over the iron to be connected, see also FIG the hook of the binding device detects the transition point 7 of the wire bracket and twists the upper part of the bracket. The fact that the connection is made from above and the wire bracket no longer has to be pushed under the irons by hand, makes the work much easier, since the operator no longer has to bend down as deep. In the following two exemplary embodiments of a binding device are described, with which it is possible to engage the locking means of the wire bracket without the operator having to take the wire bracket in hand, so that the connection is carried out by a single movement sequence of the binding device.

Die wichtigste Aufgabe des Bindegerätes ist somit, die Verschlussmittel des Bügels unterhalb der zu verbindenden Stäbe in Eingriff zu bringen und anschliessend das obenliegende Uebergangsteil des Drahtbügels zu erfassen und zu verdrillen, und dies in einem Arbeitsgang.The most important task of the binding device is thus to engage the locking means of the bracket below the rods to be connected and then to grasp and twist the transition piece of the wire bracket located above, and this in one operation.

Das Bindegerät 9 weist ein rechteckiges, hohles Gehäuse 10 auf, das in einer bevorzugten Ausführungsform zugleich als Magazin für die Drahtbügel 1 dient. An seinem vorderen Ende geht das Gehäuse 10 in ein Verschlussteil 11 über, das Schliessbacken 12 aufweist, mit denen die mit Verschlussmitteln versehenen Enden der Drahtbügelschenkel derart gebogen werden, dass die Verschlussmittel miteinander in Eingriff gelangen. Um das Gehäuse und gleitbar daran angeordnet, befindet sich das bewegliche Griffteil 13, mit welchem der vorderste Drahtbügel aus dem Magazin erfasst und nach vorne, respektiv nach unten bewegt wird. Am vorderen Bereich des Gehäuses ist eine Führungsbuchse 14 befestigt, in welcher ein gerändelter Stab 15 mit Bindehaken 16 derart angeordnet ist, dass bei einer Relativbewegung der Führungsbuchse gegenüber dem gerändelten Stab dieser in Drehung versetzt wird. Im vorderen Teil des Führungsgehäuses befindet sich ferner ein Schieber 17, der unter dem Druck einer Feder 18 nach vorne geschoben wird, um die Drahtbügel nach vorne zu stossen und den vordersten der Drahtbügel in eine Stellung zu bringen, aus welcher er vom Griffteil nach vorne geschoben werden kann. Auf dem gerändelten Stab 15 befindet sich eine Druckfeder 19, die die Führungsbuchse 14 nach Beendigung des Bindevorgangs in die Ausgangslage zurückstösst.The binding device 9 has a rectangular, hollow housing 10, which in a preferred embodiment also serves as a magazine for the wire bracket 1. At its front end, the housing 10 merges into a closure part 11 which has locking jaws 12 with which the ends of the wire bracket legs provided with closure means are bent in such a way that the closure means come into engagement with one another. Arranged around the housing and slidably there is the movable handle part 13, with which the foremost wire bracket is gripped from the magazine and moved forwards or downwards. A guide bushing 14 is fastened to the front area of the housing, in which a knurled rod 15 with binding hooks 16 is arranged such that when the guide bushing moves relative to the knurled rod, the latter is set in rotation. In the front part of the guide housing there is also a slide 17 which is pushed forward under the pressure of a spring 18 in order to push the wire bracket forward and to bring the foremost of the wire bracket into a position from which it is pushed forward by the handle part can be. On the knurled rod 15 there is a compression spring 19 which pushes the guide bush 14 back into the starting position after the binding process has ended.

Wie insbesondere aus Figur 5 hervorgeht, besteht das Gehäuse 10 aus zwei ineinandergeschachtelten, U-förmigen Gehäuseteilen, in welchen die Drahtbügel geführt sind. In der Mitte werden die Drahtbügel durch eine Leiste 20 niedergehalten, so dass sich die Bügel nicht aufeinanderschieben können. Wie aus den Figuren 1 oder 3 ersichtlich, ist das untere, U-förmig gebogene Blech 21 des Gehäuses von vorne bis nach dem Bindehaken aufgeschnitten und mündet dort, siehe insbesondere Figur 4, in eine Nase 22 mit abgeschrägtem vorderen Ende 23, an welchem der vorderste Drahtbügel anstösst. Gemäss Figur 5 sind an der Unterseite des Griffteils 13, beidseitig der Niederhalte-Leiste 20 je eine Schiebe-Leiste 24 angebracht, die in einen Schlitz 25 im oberen, U-förmigen Gehäuseteil 26 des Gehäuses 10 gleiten. Das Ende des Schlitzes 25 dient zugleich als Anschlag, um zu verhindern, dass das bewegliche Griffteil 13 weiter zurückgezogen werden kann. Wie aus Figuren 3 und 12 ersichtlich, greifen die Schiebe-Leisten 24 in die Absätze 8 des Drahtbügels, um diesen vorwärts zu schieben. Daraus geht hervor, dass das Zusammenwirken der Niederhalte-Leiste 20 mit den Schiebe-Leisten 24 und der Nase 22 bewirkt, dass jeweils nur ein Drahtbügel nach dem andern erfasst werden kann und verhindert wird, dass sich einzelne Drahtbügel aufeinanderschieben.As can be seen in particular from FIG. 5, the housing 10 consists of two nested, U-shaped housing parts in which the wire clips are guided. In the middle, the wire brackets are held down by a strip 20, so that the brackets cannot slide onto one another. As can be seen from Figures 1 or 3, the lower, U-shaped sheet 21 of the housing is cut from the front to the binding hook and there, see in particular Figure 4, opens into a nose 22 with a beveled front end 23, on which the foremost wire bracket. According to FIG. 5, a sliding bar 24 is attached to the underside of the handle part 13, on both sides of the hold-down bar 20, which slide into a slot 25 in the upper, U-shaped housing part 26 of the housing 10. The end of the slot 25 also serves as a stop to prevent the movable handle part 13 from being retracted further. As can be seen from FIGS. 3 and 12, the sliding strips 24 engage in the shoulders 8 of the wire bracket in order to push it forward. It follows that the Together effect of the hold-down bar 20 with the sliding bars 24 and the nose 22 has the effect that only one wire bracket after the other can be grasped and prevents individual wire brackets from sliding onto one another.

Im Schliessteil des Gehäuses bilden das Gehäuse-Unterteil 21 und das Gehäuse-Oberteil 26 auf beiden Seiten je einen Kanal 27, in welchem Führungskeile 28 angeordnet sind, die von oben gesehen einen dreieckigen Grundriss haben. Wie aus den verschiedenen Stellungen der Schenkel des Drahtbügels aus Figur 3 ersehen werden kann, bewirken die Führungskeile beim Hineinstossen der Drahtbügel durch den beweglichen Griffteil ein Zusammenziehen der Schenkel, bis sie von den Schliessbacken gänzlich in Schliesslage gebracht werden.In the closing part of the housing, the lower housing part 21 and the upper housing part 26 each form a channel 27 on both sides, in which guide wedges 28 are arranged, which, viewed from above, have a triangular outline. As can be seen from the various positions of the legs of the wire bracket from FIG. 3, the guide wedges cause the legs to contract when the wire bracket is pushed in, until the legs are brought completely into the closed position by the locking jaws.

Im ersten Ausführungsbeispiel wird der Drahtbügel durch bewegliche Schliessbacken verformt, um dessen Verschlussmittel zum Eingriff zu bringen. In Figur 1 wird das Gerät in offener und in Figur 3 in geschlossener Stellung gezeigt. Man erkennt eine erste, bewegliche Schliessbacke 29 und eine zweite, bewegliche Schliessbacke 30, die je um eine Drehachse 31 a bzw. 31 b drehbar sind. Die beiden Schliessbacken werden durch eine U-förmige Schliessfeder 32 betätigt, dessen Enden 32 auf die Schliessbacken wirken. Wie in den Figuren 1, 3 und 5 angedeutet, befinden sich am beweglichen Grifftei) 13 zwei Rollen 34, die auf die Schliessfeder wirken. Wie aus diesen Figuren ferner hervorgeht, bewirken die Rollen beim Vorwärtsbewegen des beweglichen Griffteils, dass die Feder zusammengedrückt wird und mit dieser Bewegung auch die beiden Schliessbacken zusammengedrückt werden. Wie aus Figur 3 erkenntlich ist, gleiten die Enden der Drahtbügel bei der Schliessbewegung zunächst entlang der schrägen Fläche 35 der Führungskeile 28 und gelangen anschliessend hinter die Nocken 37, von wo sie auf die Auflagefläche 38 an der in der Zeichnung oberen Schliessbacke und Auflagefläche 39 an der unteren Schliessbacke gelangen.In the first exemplary embodiment, the wire bracket is deformed by movable closing jaws in order to bring its closing means into engagement. In Figure 1, the device is shown in the open position and in Figure 3 in the closed position. A first, movable locking jaw 29 and a second, movable locking jaw 30 can be seen, each of which can be rotated about an axis of rotation 31 a or 31 b. The two locking jaws are actuated by a U-shaped locking spring 32, the ends 32 of which act on the locking jaws. As indicated in FIGS. 1, 3 and 5, there are two rollers 34 on the movable handle part), which act on the closing spring. As can also be seen from these figures, the rollers, when the movable handle part is moved forward, cause the spring to be compressed and with this movement the two closing jaws are also pressed together. As can be seen from FIG. 3, the ends of the wire brackets first slide along the inclined surface 35 of the guide wedges 28 during the closing movement and then pass behind the cams 37, from where they touch the bearing surface 38 on the closing jaw and bearing surface 39 shown in the drawing the lower jaw.

Die beiden Schliessbacken sind unterschiedlich ausgestaltet, da die beiden Drahtbügel-Enden nicht die gleiche Bewegung ausführen. So wird das Drahtbügel-Ende, an dem sich die Schlaufe 5 befindet, stärker gebogen als das andere Ende, an welchem sich der Verschlusshaken 4 befindet. In der oberen Schliessbacke 29 befindet sich eine Ausnehmung 40, in welche das Schlaufen-Ende des Drahtbügels aufgenommen wird. Das Ende 41 der anderen Schliessbacke 30 ist ausgefräst, um, wie in Figur 3 ersichtlich, das Drahtbügel-Ende mit dem Verschlusshaken 4 aufzunehmen. In Figur 7 ist dargestellt, wie sich der Drahtbügel in der Endlage befindet und man erkennt, dass die Schlaufe derart über den Verschlusshaken gelegt ist, dass bei einer Rückzugbewegung die Schlaufe hinter dem Haken eingreift. Aus Figur 7 ist auch ersichtlich, dass in der Endlage der Drahtbügel beidseitig aus dem durch das untere U-förmige Blech 21 und Nocken 37 gebildeten Kanal herausgleitet, da in dieser Stellung der Drahtbügel, von der Seite aus gesehen, die dünnste Stelle hat.The two locking jaws are designed differently because the two wire bracket ends do not perform the same movement. Thus, the wire bracket end on which the loop 5 is located is bent more than the other end on which the locking hook 4 is located. In the upper closing jaw 29 there is a recess 40 into which the loop end of the wire bracket is received. The end 41 of the other locking jaw 30 is milled out in order to receive the wire bracket end with the locking hook 4, as can be seen in FIG. FIG. 7 shows how the wire bracket is in the end position and it can be seen that the loop is placed over the locking hook in such a way that the loop engages behind the hook during a retraction movement. It can also be seen from FIG. 7 that in the end position the wire bracket slides out on both sides of the channel formed by the lower U-shaped plate 21 and cam 37, since in this position the wire bracket has the thinnest point, seen from the side.

Aus der Beschreibung und den Figuren 1 bis 7 ergibt sich folgender Arbeitsablauf: Beim Vorwärtsstossen des Bindegerätes über einem Kreuzungspunkt von zwei zu verbindenden Stäben A, B, stösst das Bindegerät entweder mit den Schliessbacken auf den Boden C oder mit dem Schliesshaken auf dem oberen Stab A auf, und in der weiteren Vorwärtsbewegung wird das bewegliche Griffteil 13 nach vorne geschoben. Dadurch wird der Drahtbügel, wie in Figur 3 dargestellt, in die Schliessbacken gestossen. Gleichzeitig werden die Schliessbacken geschlossen, wodurch sich die Verschluss-Schlaufe 5 über den Verschlusshaken 4 legt. Beim Zurückziehen wird zunächst die Verschluss-Schlaufe mit dem Verschlusshaken am Drahtbügel verriegelt und das ganze Bindegerät zurückgezogen. Da der Bindehaken mit dem Drahtbügel im Eingriff steht und der verriegelte Bügel beim Zurückziehen am Stab B anschlägt, wird der Bindehaken durch die Aufwärtsbewegung der Führungsbuchse in Drehung versetzt und der Drahtbügel am oberen Ende bei der Uebergangsstelle verdrillt. Nun braucht nur noch der Bindehaken aus der nach der Verdrehung gebildeten Oese herausgezogen zu werden und die Verbindung ist hergestellt.The description and Figures 1 to 7 show the following workflow: When pushing the binding device forward over a crossing point of two rods A, B to be connected, the binding device either hits the bottom C with the locking jaws or with the locking hook on the upper rod A on, and in the further forward movement the movable handle part 13 is pushed forward. As a result, the wire bracket, as shown in FIG. 3, is pushed into the closing jaws. At the same time, the locking jaws are closed, as a result of which the locking loop 5 is placed over the locking hook 4. When pulling back, the locking loop is first locked with the locking hook on the wire bracket and the entire binding device is pulled back. Since the binding hook is in engagement with the wire bracket and the locked bracket strikes rod B when it is pulled back, the binding hook is rotated by the upward movement of the guide bushing and the wire bracket is twisted at the upper end at the transition point. Now only the binding hook needs to be pulled out of the eyelet formed after the twisting and the connection is made.

Gemäss einem zweiten Ausführungsbeispiel nach Figur 8 können das Schliessteil und die Führungsbacken wesentlich vereinfacht werden. Das Gerät mitsamt dem beweglichen Griffteil ist mit Ausnahme des Verschlussteils dasselbe wie vorgehend beschrieben. Das Verschlussteil 42 enthält im Gegensatz zum ersten Ausführungsbeispiel keine beweglichen, sondern nur noch zwei starre Schliessbacken 43, die gleich gearbeitet sein können. Die starren Schliessbacken 43 weisen eine bogenförmige Schliesskante 44 auf, durch die die beiden Enden des Drahtbügels gegeneinander geführt werden, um in die in Figur 7 gezeichnete Schliesslage zu kommen. Ausserdem werden die Drahtbügel-Enden durch je einen Nocken 45, der gegenüber der Schliesskante angeordnet ist, auf diese Schliesskante unter einem geeigneten Winkel gelenkt, wobei dieser Nocken eine etwa halbkreisförmige Führungsfläche aufweist. Die Funktion dieses Verschlussteiles ist die gleiche wie beim ersten Ausführungsbeispiel, hat jedoch den Vorteil, kein bewegliches Teil aufzuweisen.According to a second exemplary embodiment according to FIG. 8, the closing part and the guide jaws can be considerably simplified. The device together with the movable handle part is the same as described above with the exception of the locking part. In contrast to the first exemplary embodiment, the closure part 42 does not contain any movable, but only two rigid closing jaws 43, which can be worked in the same way. The rigid closing jaws 43 have an arcuate closing edge 44 through which the two ends of the wire bracket are guided against one another in order to come into the closed position shown in FIG. In addition, the wire bracket ends are each directed to this closing edge at a suitable angle by a cam 45, which is arranged opposite the closing edge, this cam having an approximately semicircular guide surface. The function of this closure part is the same as in the first exemplary embodiment, but has the advantage that it has no moving part.

Um die einem erheblichen Verschleiss unterworfenen Schliessbacken 43 leicht austauschen zu können, sind diese mit einer Schraube 46 am unteren Gehäuseteil 21 befestigt.In order to be able to easily replace the closing jaws 43, which are subject to considerable wear, they are fastened to the lower housing part 21 with a screw 46.

Aus der Beschreibung geht hervor, dass es mit diesem neuen Gerät möglich ist, in einer Hin- und Herbewegung, ohne sich bei Bodenarmierungen bücken zu müssen, zwei Stäbe miteinander zu verbinden. Da der ganze Arbeitsvorgang nur aus einem Stossen und Ziehen besteht, können auch weniger qualifizierte Personen für diese Arbeiten eingesetzt werden. Im Rahmen der vorliegenden Erfindung können verschiedene Einzelheiten anders gestaltet werden. So ist es beispielsweise möglich, das Magazinteil derart zu gestalten, dass auf einem geeigneten Träger wie Karton oder Plastik aufgezogene Drahtbügel in das Gerät eingeschoben werden können. Ferner kann das die Drahtbügel enthaltende Magazin seitwärts am Gehäuse des Bindegerätes, d.h. quer zur Schliessbewegung angeordnet sein, wobei das Gerät eine entsprechende Oeffnung aufweist und der die einzelnen Drahtbügel nach vorne stossende Schieber entsprechend ausgebildet ist.The description shows that it is possible with this new device to connect two rods in a to-and-fro movement without having to bend down with floor reinforcements. Since the whole process consists of just pushing and pulling, less qualified people can also be used for this work. Various details can be designed differently within the scope of the present invention. For example, it is possible to design the magazine part in such a way that on a suitable carrier such as cardboard or Plastic wire brackets can be inserted into the device. Furthermore, the magazine containing the wire brackets can be arranged sideways on the housing of the binding device, ie transversely to the closing movement, the device having a corresponding opening and the slide which pushes the individual wire brackets forward is designed accordingly.

Ausserdem ist es möglich, die Verschlussmittel am Drahtbügel anders zu gestalten, d.h. den Verschlusshaken und die Verschluss-Schlaufe in eine andere Ebene zu verlegen. Das bedeutet in Bezug auf Figur 9, dass der Verschlusshaken 4 aus der durch die V-förmig angeordneten Schenkel gebildeten Ebene nach oben oder unten heraussteht und das schlaufenförmige Ende von Schenkel 3 dementsprechend gebogen ist.It is also possible to design the locking means on the wire bracket differently, i.e. to move the locking hook and the locking loop to a different level. In relation to FIG. 9, this means that the locking hook 4 protrudes upward or downward from the plane formed by the V-shaped legs and the loop-shaped end of leg 3 is bent accordingly.

Zur weiteren vereinfachten Arbeit ist es möglich, die Verdrillung anstatt durch Ziehen des Gerätes durch einen batteriebetriebenen Antrieb durchzuführen, um ein schnelleres, kräftesparendes Arbeiten zu ermöglichen.For further simplified work, it is possible to carry out the twisting instead of pulling the device by means of a battery-operated drive, in order to enable faster, energy-saving work.

In den Figuren 13a bis 27 ist ein weiteres, bevorzugtes Ausführungsbeispiel beschrieben, das an das zweite Ausführungsbeispiel mit festen Backen anknüpft und eine weitere Verbesserung bezüglich sicheres Einhaken der Drahtbügel sowie deren Vereinzelung und sicheres Einschieben in die Schliessvorrichtung bewirkt. Wie im einzelnen noch ausgeführt werden wird, wird diese Verbesserung dadurch erzielt, dass ein beweglicher Teil im Schliessbereich einerseits den Drahtbügel in eine sichere Schliess-Stellung bringt und andererseits eine sichere Vereinzelung der Drahtbügel, um sie sicher in die richtige Ausgangslage zu bringen.A further preferred exemplary embodiment is described in FIGS. 13a to 27, which ties in with the second exemplary embodiment with fixed jaws and brings about a further improvement with regard to securely hooking in the wire clips and separating them and securely inserting them into the locking device. As will be explained in more detail, this improvement is achieved in that a movable part in the closing area on the one hand brings the wire bracket into a secure closing position and on the other hand a secure separation of the wire bracket in order to bring it securely into the correct starting position.

Wie insbesondere aus den Fig. 14a und b sowie 18 hervorgeht, ist der gerändelte Stab 15 mit dem Bindehaken 16 parallel zum Gehäuse 50 des Bindegerätes 51 und somit auch zum Griffteil 52 angeordnet, womit eine besonders kompakte und raumsparende Anordnung möglich ist. Das Gehäuse 50 geht an seinem vorderen Ende in ein Verschlussteil 53 über, das zwei starre Schliessbacken 54 und 55 aufweist. Der gerändelte Stab 15 ist hinten in einer elastischen Lagerung 56 drehbar gelagert und befestigt. Die Lagerung 56 ist mittels elastischen Verbindungen 107 mit zwei Federn 108 in Federhäusern verbunden, die mit dem Griffteil verbunden sind. Man erkennt in Fig. 14a ferner den Deckel 57, der hinten, d.h. in der Zeichnung links, an einer Lagerung 58 angelenkt ist. Im vorderen Bereich des Gehäuses, siehe Fig. 18, ist eine aus zwei Rollen bestehende Führungsbuchse 59 angeordnet, mittels welcher der gerändelte Stab mit dem Bindehaken in Drehung versetzt werden kann. Man erkennt in Fig. 13a einen von den Bandfedern 69 beaufschlagten Bügelschieber 60, der die Drahtbügel 61 in Vorwärtsrichtung stösst, wobei die Bandfedern auf den Federrollen 70 ablaufen.As can be seen in particular from FIGS. 14 a and b and 18, the knurled rod 15 with the binding hook 16 is arranged parallel to the housing 50 of the binding device 51 and thus also to the handle part 52, which enables a particularly compact and space-saving arrangement. The housing 50 merges at its front end into a closure part 53 which has two rigid locking jaws 54 and 55. The knurled rod 15 is rotatably mounted and fastened in the rear in an elastic bearing 56. The bearing 56 is connected by means of elastic connections 107 to two springs 108 in spring barrels which are connected to the handle part. The lid 57 can also be seen in FIG. in the drawing on the left, is hinged to a bearing 58. In the front area of the housing, see FIG. 18, a guide bushing 59 consisting of two rollers is arranged, by means of which the knurled rod with the binding hook can be set in rotation. One can see in FIG. 13 a a strap slide 60 acted upon by the ribbon springs 69, which pushes the wire clips 61 in the forward direction, the ribbon springs running on the spring rollers 70.

Das Griffteil 52 mit dem Griff 62 ist am hinteren Ende mit einer Bolzenschraube 63, die in einem Schlitz 64 im Gehäuseboden 65 gleitet, mit diesem verbunden und weist ferner eine Stockführung 106 auf, mit welcher mittels eines Verlängerungsstockes das Gerät aufrecht bedient werden kann, falls Verbindungen am Boden herzustellen sind. Das vordere Ende des Griffteils ist über zwei Schraubenbolzen 66 mit einem T-Stück 67 verbunden, das im Gehäuseunterteil gleitet und eine vielfältige Aufgabe hat, wobei die Schraubenbolzen in einem Längsschlitz 72 im Gehäuseboden 65 gleiten. Oberhalb des Längsschenkels 87 des T-Stücks ist ein mit diesem über eine Feder 89 verbundener Schieber 88 gleitbar angeordnet, der an seinem vorderen Teil zwei Nasen 76 trägt, die in zwei Absätze 77 im jeweils vordersten Drahtbügel 61a greifen.The handle part 52 with the handle 62 is connected at the rear end with a bolt 63, which slides in a slot 64 in the housing base 65, and also has a stick guide 106, with which the device can be operated upright by means of an extension stick if Ground connections are to be made. The front end of the handle part is connected via two screw bolts 66 to a T-piece 67 which slides in the lower housing part and has a diverse function, the screw bolts sliding in a longitudinal slot 72 in the housing base 65. Above the longitudinal leg 87 of the T-piece, a slide 88 connected to the latter via a spring 89 is slidably mounted, which carries on its front part two lugs 76 which engage in two shoulders 77 in the foremost wire bracket 61a.

Anhand der Fig. 15, 16 und 17 wird nun die Schliessbewegung geschildert, wobei die vielfältigen Aufgaben des T-Stücks sowie der durch dieses T-Stück bewegten Teile erläutert werden. In Fig. 15 befindet sich das Gerät in der Ausgangsstellung, wobei der vorderste Drahtbügel 61a a gegebenenfalls mittels einer Ladebewegung in diese Ausgangsstellung gebracht worden ist. Der vorderste Drahtbügel 61a befindet sich ohne Druck im Gerät, wobei der durch den Bügelschieber 60 ausgeübte Druck vom dahinter angeordneten Drahtbügel 61 b aufgefangen wird, dessen beiden Enden an einem Absatz 73 einer Klinke 74 mit Drehpunkt 75 anliegen. Bei der Vorwärtsbewegung des Griffteils 52 wird das mit diesem verbundene T-Stück 67 ebenfalls vorwärts bewegt, bis es sich in der in Figur 16 gezeigten Stellung befindet, wobei die Nasen 76 am Schieber 88 den vordersten Drahtbügel 61a an seinen Absätzen 77 mitnehmen und die Vorderfront des Schiebers an den Anschlagstücken 71 der beiden Schliessbacken anstösst. Dabei geraten die Verschlussteile des Drahtbügels, siehe Fig.16, in je einen Führungskanal 78 und 79, werden diesen entsprechend gekrümmt und in die Schliesslage gebracht. Während der-in der Zeichnung obere-Führungskanal 78 eine Einfräsung in der oberen Schliessbacke 54 ist, befindet sich der andere Führungskanal 79 in einem Drehstück 80, das um einen Zapfen 81 drehbar gelagert ist.15, 16 and 17, the closing movement is now described, the various tasks of the T-piece and the parts moved by this T-piece are explained. 15, the device is in the starting position, the foremost wire bracket 61a a possibly being brought into this starting position by means of a loading movement. The foremost wire bracket 61a is in the device without pressure, the pressure exerted by the bracket slide 60 being absorbed by the wire bracket 61b arranged behind it, the two ends of which abut a shoulder 73 of a pawl 74 with a pivot point 75. When the handle part 52 moves forward, the T-piece 67 connected to it is also moved forward until it is in the position shown in FIG. 16, the lugs 76 on the slide 88 taking the foremost wire bracket 61a with its shoulders 77 and the front face of the slide against the stop pieces 71 of the two locking jaws. The locking parts of the wire bracket, see FIG. 16, each get into a guide channel 78 and 79, these are curved accordingly and brought into the closed position. While the upper guide channel 78 in the drawing is a milling in the upper closing jaw 54, the other guide channel 79 is located in a rotating piece 80 which is rotatably mounted about a pin 81.

Bei der anschliessenden Vorwärtsbewegung, beim Uebergang zur Stellung von Figur 17, wird nur noch das T-Stück 67 gegen den Druck der Feder 89 vorwärts bewegt, wobei seine kurzen Schenkel 68 zwei in den Schliessbacken angeordnete Kurvenschieber 85, 85a betätigen, die von je einer Feder 105 beaufschlagt sind. Beide Kurvenschieber tragen je einen Klinkenstift 82 zur Betätigung der Klinken 74, während einer, 85a, der beiden Kurvenschieber ausserdem noch eine Schulter 84 aufweist, die auf einen Stift 86 am Drehstück 80 wirkt, um diesen zu drehen. Anschliessend an die Kurvenschieber sind feste Kurvenstücke mit Einbuchtung 103 geformt, in denen - siehe Fig. 17 - der dritte Drahtbügel 61c in dem Moment anliegt, in dem der zweite Bügel 61 frei wird. Das Drehen des Drehstücks bewirkt, dass der im Führungskanal 79 sich befindliche Teil des Drahtbügels nach auswärts gedreht wird, um den Verschluss des Drahtbügels in einen sicheren Eingriff zu bringen.In the subsequent forward movement, at the transition to the position of FIG. 17, only the T-piece 67 is moved forward against the pressure of the spring 89, its short legs 68 actuating two cam slides 85, 85a arranged in the locking jaws, each of which Spring 105 are acted upon. Both cam slides each carry a pawl pin 82 for actuating the pawls 74, while one, 85a, of the two cam slides also has a shoulder 84 which acts on a pin 86 on the rotary piece 80 in order to rotate it. Following the cam slides, fixed curve pieces with indentation 103 are formed, in which - see FIG. 17 - the third wire bracket 61c rests at the moment when the second bracket 61 becomes free. The rotation of the rotating piece causes the part of the wire bracket located in the guide channel 79 to be turned outwards in order to bring the closure of the wire bracket into a secure engagement.

Beim Zurückziehen des Griffteils werden die Klinken 74 in ihre Ausgangslage gebracht und der Drahtbügel 61c stösst auf den Absatz 73 der Klinke, während der nun vorderste Drahtbügel 61b drucklos ist und in die Führungskanäle gestossen werden kann. Dazu muss dieser jedoch vorher von den entsprechend geformten Nasen 76 am Schieber nach oben gehoben werden. Damit der vorderste Drahtbügel nach dieser Operation sicher an den Nasen anliegt, wird dieser mittels einer Feder 109 nach unten gedrückt, siehe Fig. 18.When the handle part is pulled back, the pawls 74 are brought into their initial position and the wire bracket 61c hits the shoulder 73 of the pawl, while the foremost wire bracket 61b is now depressurized and can be pushed into the guide channels. To do this, however, it must first be lifted upwards by the correspondingly shaped lugs 76 on the slide. So that the foremost wire bracket lies securely on the noses after this operation, it is pressed down by means of a spring 109, see FIG. 18.

Gleichzeitig befindet sich der Uebergangsteil 98 zwischen den beiden Schenkeln des Drahtbügels im Bindehaken, wobei dieser beim Zurückziehen des Bindegerätes durch die Führungsbuchse in Drehung versetzt wird und den Drahtbügel verdrillt. Nach dem Verdrillen braucht nur noch der Bindehaken aus der nach der Verdrehung gebildeten Oese herausgezogen zu werden und die gewünschte Verbindung ist hergestellt.At the same time, the transition part 98 is located between the two legs of the wire bracket in the binding hook, which is rotated by the guide bush when the binding device is withdrawn and the wire bracket is twisted. After twisting, only the binding hook needs to be pulled out of the eyelet formed after the twisting and the desired connection is made.

Von den Fig. 19-21 ausgehend erkennt man, dass das Gehäuse 50 ein U-förmiges Unterteil mit dem Gehäuseboden 65 und den beiden Seitenwänden 90 aufweist und dass am Gehäuseboden eine Führung 91 angeordnet ist, die ebenfalls U-förmig mit daran anschliessenden, waagrechten Schenkeln 92 ausgebildet ist. Diese Führung hat eine zweifache Aufgabe: Zuerst dient sie als Führung für die Drahtbügel 61, und dann als Führung des Bügelschiebers 60. Der Deckel 57 weist ausserdem zwei Führungsleisten 93 auf, um die Drahtbügel niederzuhalten und zu führen.19-21 it can be seen that the housing 50 has a U-shaped lower part with the housing base 65 and the two side walls 90 and that a guide 91 is arranged on the housing base, which is also U-shaped with adjoining, horizontal Legs 92 is formed. This guide has a two-fold function: first it serves as a guide for the wire bracket 61, and then as a guide for the bracket slide 60. The cover 57 also has two guide strips 93 to hold down and guide the wire bracket.

Im Vergleich zum Drahtbügel 1 weist der Drahtbügel 61a eine eckigere Form auf, wobei insbesondere die Schulter 77 ausgeprägt ist und annähernd rechtwinklig ist, um einen guten Eingriff der Nocken 76 am Schieber 88 zu gewährleisten. Der eine Verschluss-Schenkel 94 ist breiter als der andere Schenkel 95, und der Haken 96 ist in diesem Ausführungsbeispiel in der gleichen Ebene wie der bestehende Verschluss-Schenkel 94. Im vorliegenden Beispiel besteht der Drahtbügel aus zwei Drähten 101, 102, die an vier Punkten 97 zusammengeschweisst sind. Beim Uebergang 98 zwischen den beiden Verschluss-Schenkeln sind die beiden Drähte offen, um das Kunststoffband 99 zwischen sich aufzunehmen. Das Kunststoffband ist lediglich ein Verpackungs- und Transportband. Nach dem Laden des Bandes mit den Drahtbügeln in die Maschine wird das Band entfernt.Compared to the wire bracket 1, the wire bracket 61a has a more angular shape, the shoulder 77 in particular being pronounced and being approximately rectangular in order to ensure good engagement of the cams 76 on the slide 88. One closure leg 94 is wider than the other leg 95, and in this exemplary embodiment the hook 96 is in the same plane as the existing closure leg 94. In the present example, the wire bracket consists of two wires 101, 102 connected to four Points 97 are welded together. At the transition 98 between the two closure legs, the two wires are open to accommodate the plastic band 99 between them. The plastic belt is just a packaging and transport belt. After loading the tape with the wire clips into the machine, the tape is removed.

In der geschlossenen Stellung gemäss Fig. 17 sieht man, dass der schmälere Verschluss-Schenkel 95 in den breiteren Verschluss-Schenkel 94 fasst und die untere Verschluss-Schlaufe 100 des schmäleren Verschluss-Schenkels hinter den Haken 96 greift. Die Drahtbügel können wie in Fig. 25 oder 26 verschweisst werden oder aus einem einzigen Draht 6 geformt sein, wie gemäss Fig. 27.In the closed position according to FIG. 17 it can be seen that the narrower closure leg 95 fits into the wider closure leg 94 and the lower closure loop 100 of the narrower closure leg engages behind the hook 96. The wire brackets can be welded as in FIG. 25 or 26 or formed from a single wire 6, as in FIG. 27.

Auch bei der bevorzugten Ausführungsvariante ist es möglich, die Verdrillung beim Ziehen des Gerätes durch einen batteriebetriebenen Antrieb durchzuführen. In den bis jetzt beschriebenen Ausführungsbeispielen wurde der Einfachheit halber ein Bindehaken verwendet, doch ist es auch möglich, statt dessen einen Greifmechanismus vorzusehen.Even in the preferred embodiment variant, it is possible to carry out the twisting when pulling the device by means of a battery-operated drive. In the exemplary embodiments described so far, a binding hook has been used for the sake of simplicity, but it is also possible to provide a gripping mechanism instead.
