Definitions
- the invention relates to a binding tool for assembling binding wire according to the preamble of patent claim 1.
- Reinforced concrete is a composite building material made of concrete and steel, in which the compressive forces are absorbed by the concrete and the tensile forces and greater shear forces are absorbed by the steel as reinforcement.
- the reinforcement is often made on site. When laying the reinforcing elements, called reinforcing bars in specialist circles, they must be secured in their mutual position by fastening elements, i. H. especially at the crossing points.
- binding wires are known as fastening elements.
- a wide variety of binding tools for assembling these binding wires are also known.
- the known binding tools have, in the manner of a drill bit, a drive shaft with a steep thread, which is set in rotary motion by moving up and down a corresponding handle with a nut (threaded sleeve).
- the drive shaft has at its lower end a holding member for receiving the two end sections of a binding wire.
- a binding tool of this type is described for example in the patent specification CH 160 109.
- the binding wire which has a loop at both ends.
- the holding member of the binding tool is designed for this binding wire according to the prior art as a hook on which the two loops of a binding wire can be hung.
- the binding wire is attached to the hook of the binding tool with the one loop.
- the binding wire is bent by hand around the reinforcing iron to be connected and also attached to the hook of the binding tool with the other loop.
- the two end sections of the binding wire are twisted (twisted) by actuating the binding tool.
- this type of fastening has the disadvantage that the wire loops sometimes become jammed on the hook of the binding tool when twisting the binding wire and are then difficult to detach from the hook.
- the patent US 4,947,902 proposes a binding tool, the holding member of which is in the form of two hooks. After attaching a binding wire, these two hooks are swung forward. This should make it easier to detach the wire from the hook.
- this binding tool has the disadvantage that the hooks do not tip forward if the loops are tightened too little. Since this binding tool also does not work reliably, it could not prevail in practice.
- the so-called drill crank is also known on the market. It does not need a handle, which is moved up and down on a steep thread, but it has a fixed handle at the back, which is connected to the front fastening part with a ball bearing. Since the connection axis between the ball bearing and the front fastening part is slightly curved, you can, holding the binding tool by the rear handle, rotate the front fastening part by circular movements with the arm that holds the binding tool and thus twist the wires attached to it.
- Another well-known development is the so-called "automat”. With him the drive shaft is pulled back again and again by a spring, ie brought into the starting position.
- US Pat. No. 5,542,228 describes a binding tool that is equipped with a magazine for a large number of two-legged binding wires, which are placed semi-automatically around the reinforcing bars and bent so that hooks are formed at the ends of the binding wires, with which the reinforcing bars clamped together and can be pulled together.
- the binding tool described in the patent has no convincing advantages over the other binding tools described so far.
- the object of the present invention is to create a binding tool of the type mentioned at the outset, which can be used more universally.
- the proposed binding tool for assembling binding wires comprises a drive shaft with steep thread, which carries at one end a holding device having a fixing device for receiving the two end sections of a binding wire.
- the drive shaft can be rotated by moving up and / or down a handle matching the steep thread, which is provided with a nut thread on the inside.
- the proposed holding device can be implemented in three variants.
- the holding device is designed in such a way that an eyelet-free binding wire and also a binding wire can be inserted into the holding device without thickening at its end sections and fixed there.

- Fig. 4c a schematic representation of the rear profile of the
- the proposed binding tool is shown in Fig. 1a, a more detailed view of the holding device 1 to emphasize the mutual orientation of the individual parts is shown in Fig. 1b.
- the proposed binding tool consists of a drive shaft 3 with steep thread 2.
- the drive shaft 3 carries at one end a binding wire holding device 1, which is used by means of a fixing device for securely receiving the end sections of an eyelet-free binding wire or one which is not thickened at its end sections.
- the drive shaft 3 is manually rotated by the movement of a handle 4 (with a nut thread on the inside) that matches the steep thread 2.
- the holding device 1 consists of a base body with the corner jaw 8 and the holding jaw 10 attached to the outside.
- the wire is fixed to the holding device in that the binding tool is held with one hand, while the other end of the binding wire is placed in the holding slot 9. Now the free area of this first end of the binding wire is bent into the side slot 7 arranged between the central jaw 5 and the one corner jaw 8, which tapers slightly conically towards the bottom. If the binding wire at the other free end is now pulled away from the binding tool, the fixed end of the binding wire is wedged due to the conical taper in the side slot 7, as a result of which the binding wire is anchored in the holding device 1 and remains firmly seated in the holding device 1. The other free end of the The binding wire is now guided around the reinforcing bars to be connected and then inserted into the central slot 6.
- the binding wire When this end of the binding wire is inserted into the central slot 6, the binding wire is deformed and slightly scored at the points where it comes into contact with the cutting edges 11, so that it is secured against inadvertent slipping out (or pulling out) from the central slot 6 , This securing takes place in that the wire, which is first in the upper part of the slot, is guided forward and downward through the oblique cutting edges 11 and is thereby drawn further and further into the slot when it is pulled.
- the handle 4 When inserting the binding wire in the holding device 1, the handle 4 should be in the vicinity of the holding device 1. If the binding wire is inserted with both ends, the handle 4 (which has a nut thread on the inside) on the drive shaft 3 is pulled away from the holding device 1. Since the drive shaft 3 has a steep thread 2 and the handle 4 is held in the hand, ie does not rotate, the drive shaft 3 and thus the holding device 1 together with the binding wire must rotate. As a result, the two ends of the binding wire are twisted together, as a result of which the binding wire is pulled tightly around the reinforcing bars and thereby firmly ties the reinforcing bars together.
- the holding device can be constructed mirror-symmetrically, ie the device with side slot 7 and holding slot 9 then comes to rest on the other side of the holding device 1, as is shown in FIGS. 2a and b.
- 2 shows an embodiment which is suitable for both right-handed and left-handed users is suitable in that a side slot 7 and a holding slot 9 with the corresponding additional corner jaw 12 are provided on both sides of the holding device. This means that either slots 7 and 9 on the right or left side can be used, depending on whether you are right-handed or left-handed.
- 1 and 2 show the 1st variant, in which the two ends of the binding wire are accommodated in differently constructed slots.
- this variant there are embodiments which are only intended for right-handers, only for left-handers or for both.
- 3a and 3b represent the second variant of the proposed binding tool.
- This advantageous further development is characterized in that it has only one central slot 6, in which first one end of the binding wire and later after the binding wire has been placed around the reinforcing bars to be connected , the second wire end is also inserted.
- the advantage of this variant is that it can be operated by right-handed and left-handed people, as well as the lower manufacturing effort.
- Fig. 4 shows the third variant of the proposed binding tool.
- the holding device has two identical slots, each with two opposing cutting edges.
- the two universal slots 13 taper against the base of the holding device.
- the binding wire is first placed in one of the two universal slots 13, where it is scored and thus fixed by the cutting edges 14 forming the fixing device. After the wire has been placed around the reinforcing bars, the other end of the wire is placed in the still free slot, where it is also fixed by the two cutting edges 14 becomes.
- This variant can also be operated by left-handed as well as right-handed people.
- the proposed binding tool is a very simple tool, which has clear advantages over the binding tools described in practice and over the binding tools described in the patent literature. It replaces the old, well-known devices, which have a hook at the front and for which you could only use wires with eyelets. With this new tool you can work like with the old ones. The big difference, however, is that you no longer need wires with eyelets for this device, but can work with simple, eyelet-free wires. Inserting and fixing the binding wire in the holding device is easy and safe.
- a particular advantage of the proposed binding tool is the possibility of using straight binding wires without looped ends and without thickened ends and with any cross section.
- binding wires can be produced much more easily and can therefore also be produced at much lower production costs by simply cutting them to a certain length from the reel. But the storage of these binding wires is also easier, and they are also much easier to remove from a corresponding storage jar during construction.
- a wire is preferably used, which is coated with plastic. The plastic sheathing is scratched through the cutting edges 11, the binding wire is fixed in this way. Since the production of looped and welded binding wires is relatively expensive in comparison to unshaped wires, the use of the proposed binding tool for straight binding wires without eyelets or thickening results in a significant cost advantage. Since working with the binding wire without eyelets is much easier than with those with eyelets, the proposed solution can be inserted into the binding tool and twisted without removing the work gloves.
- the proposed binding tool is not only suitable for connecting reinforcing bars, but generally for connecting two or more objects lying one on top of the other or next to one another.
- This binding tool can also be used, for example, to close bags or to fix electrical cables.

Description
Bindewerkzeug zur Montage von Bindedraht zwecks gegenseitiger Sicherung übereinanderliegender Gegenstände Binding tool for the assembly of binding wire for the mutual securing of objects lying one above the other
Die Erfindung betrifft ein Bindewerkzeug zur Montage von Bindedraht gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a binding tool for assembling binding wire according to the preamble of patent claim 1.
Stahlbeton ist ein Verbundbaustoff aus Beton und Stahl, bei dem vom Beton die Druckkräfte und vom Stahl als Armierung vor allem die Zugkräfte und grössere Schubkräfte aufgenommen werden. Die Armierung wird häufig auf der Baustelle gefertigt. Beim Verlegen der Armierungselemente, in Fachkreisen Armierungseisen genannt, müssen dieselben in ihrer gegenseitigen Lage durch Befestigungsorgane gesichert werden, d. h. vor allem an den Kreuzungsstellen miteinander verbunden werden.Reinforced concrete is a composite building material made of concrete and steel, in which the compressive forces are absorbed by the concrete and the tensile forces and greater shear forces are absorbed by the steel as reinforcement. The reinforcement is often made on site. When laying the reinforcing elements, called reinforcing bars in specialist circles, they must be secured in their mutual position by fastening elements, i. H. especially at the crossing points.
Gemäss dem heutigen Stand der Technik sind als Befestigungsorgane verschiedene Arten von Bindedrähten bekannt. Ebenfalls bekannt sind die unterschiedlichsten Bindewerkzeuge zur Montage dieser Bindedrähte.According to the current state of the art, various types of binding wires are known as fastening elements. A wide variety of binding tools for assembling these binding wires are also known.
Die bekannten Bindewerkzeuge weisen in der Art eines Drillbohrers eine Triebwelle mit Steilgewinde auf, die durch Auf- und Abbewegung eines entsprechenden Handgriffes mit Mutter (Gewindehülse) in Drehbewegung versetzt wird. Die Triebwelle weist an ihrem unteren Ende ein Halteorgan zur Aufnahme der beiden Endabschnitte eines Bindedrahtes auf. Ein Bindewerkzeug dieser Art wird beispielsweise in der Patentschrift CH 160 109 beschrieben.The known binding tools have, in the manner of a drill bit, a drive shaft with a steep thread, which is set in rotary motion by moving up and down a corresponding handle with a nut (threaded sleeve). The drive shaft has at its lower end a holding member for receiving the two end sections of a binding wire. A binding tool of this type is described for example in the patent specification CH 160 109.
Am weitesten verbreitet ist der Bindedraht, welcher an seinen beiden Enden je eine Schlaufe aufweist. Das Halteorgan des Bindewerkzeugs ist für diesen Bindedraht gemäss dem Stand der Technik als Haken ausgebildet, an welchem sich die beiden Schlaufen eines Bindedrahtes einhängen lassen. Beim Verlegen der Armierungseisen wird in diesem Fall in einem ersten Schritt der Bindedraht mit der einen Schlaufe am Haken des Bindewerkzeugs eingehängt. Danach wird der Bindedraht von Hand um die zu verbindenden Armierungseisen gebogen und mit der anderen Schlaufe ebenfalls am Haken des Bindewerkzeugs eingehängt. Schliesslich werden die beiden Endabschnitte des Bindedrahtes durch Betätigung des Bindewerkzeugs zusammengedreht (verdrillt). Diese Befestigungsart ist jedoch mit dem Nachteil verbunden, dass sich die Drahtschlaufen beim Verdrehen des Bindedrahtes manchmal am Haken des Bindewerkzeugs verklemmen und sich dann nur schwer vom Haken lösen lassen. Zur Lösung dieses Problems schlägt die Patentschrift US 4,947,902 ein Bindewerkzeug vor, dessen Halteorgan die Form von zwei Haken hat. Nach dem Anbringen eines Bindedrahtes werden diese beiden Haken nach vorne geschwenkt. Dadurch soll das Lösen des Drahtes von den Haken erleichtert werden. Dieses Bindewerkzeug hat jedoch den Nachteil, dass die Haken nicht nach vorne kippen, wenn die Schlaufen zuwenig zusammengezogen werden. Da auch dieses Bindewerkzeug nicht zuverlässig arbeitet, konnte es sich in der Praxis nicht durchsetzen.The most common is the binding wire, which has a loop at both ends. The holding member of the binding tool is designed for this binding wire according to the prior art as a hook on which the two loops of a binding wire can be hung. In this case, when the reinforcing bars are laid, the binding wire is attached to the hook of the binding tool with the one loop. Then the binding wire is bent by hand around the reinforcing iron to be connected and also attached to the hook of the binding tool with the other loop. Finally, the two end sections of the binding wire are twisted (twisted) by actuating the binding tool. However, this type of fastening has the disadvantage that the wire loops sometimes become jammed on the hook of the binding tool when twisting the binding wire and are then difficult to detach from the hook. To solve this problem, the patent US 4,947,902 proposes a binding tool, the holding member of which is in the form of two hooks. After attaching a binding wire, these two hooks are swung forward. This should make it easier to detach the wire from the hook. However, this binding tool has the disadvantage that the hooks do not tip forward if the loops are tightened too little. Since this binding tool also does not work reliably, it could not prevail in practice.
Auf dem Markt ist aber auch die sogenannte Drillkurbel bekannt. Sie benötigt keinen Handgriff, welcher auf einem Steilgewinde auf und ab bewegt wird, sondern sie verfügt hinten über einen festen Handgriff, welcher mit einem Kugellager mit dem vorderen Befestigungsteil verbunden ist. Da die Verbindungsachse zwischen Kugellager und vorderem Befestigungsteil leicht gebogen ist, kann man, das Bindewerkzeug am hinteren Handgriff haltend, durch Kreisbewegungen mit dem Arm, welcher das Bindewerkzeug hält, den vorderen Befestigungsteil drehen und damit die daran fixierten Drähte verdrillen. Eine andere bekannte Weiterentwicklung ist der sogenannte "Automat". Bei ihm wird die Triebwelle durch eine Feder immer wieder zurückgezogen, d. h. in die Ausgangsstellung gebracht.The so-called drill crank is also known on the market. It does not need a handle, which is moved up and down on a steep thread, but it has a fixed handle at the back, which is connected to the front fastening part with a ball bearing. Since the connection axis between the ball bearing and the front fastening part is slightly curved, you can, holding the binding tool by the rear handle, rotate the front fastening part by circular movements with the arm that holds the binding tool and thus twist the wires attached to it. Another well-known development is the so-called "automat". With him the drive shaft is pulled back again and again by a spring, ie brought into the starting position.
Im Weiteren hat der Anmelder des vorliegenden Patentes in der Offenlegungsschrift DT 2126734 ein Bindewerkzeug gemäss dem Oberbegriff des Patentanspruchs 1 mit Triebwelle und Handgriff mit Mutter beschrieben, dessen Halteorgan die Aufnahme eines Bindedrahtes erlaubt, dessen beiden Enden verdickt sind. Das Halteorgan weist dafür einen sich verjüngenden Schlitz auf. Ein mit einem Schlitz versehenes, hakenförmiges Halteorgan wird zudem auch von der bereits erwähnten Patentschrift CH 160 109 beschrieben. Ferner schlägt die Patentschrift CH 334 934 einen für ein derartiges Halteorgan geeigneten Bindedraht vor, welcher an beiden Enden eine Verdickung aufweist. Dieses Bindewerkzeug konnte sich jedoch in der Praxis nicht durchsetzen, da sich die Bindedrähte häufig im Halteorgan verklemmen und sich dann nur schwer wieder aus diesem herausnehmen lassen. Zudem ist die Herstellung von Bindedrähten, welche an beiden Enden eine Verdickung aufweisen, kostspielig.Furthermore, the applicant of the present patent in published patent application DT 2126734 has described a binding tool according to the preamble of claim 1 with a drive shaft and a handle with a nut, the holding member of which allows the reception of a binding wire, the two ends of which are thickened. For this purpose, the holding member has a tapering slot. A hook-shaped holding member provided with a slot is also described by the already mentioned patent specification CH 160 109. Furthermore, patent specification CH 334 934 proposes a binding wire suitable for such a holding member, which has a thickening at both ends. However, this binding tool could not prevail in practice, since the binding wires often jam in the holding member and are then difficult to remove from it. In addition, the production of binding wires, which have a thickening at both ends, is expensive.
Zusätzlich wird in der Patentschrift US 5,542,228 ein Bindewerkzeug beschrieben, das mit einem Magazin für eine grössere Anzahl zweischenkliger Bindedrähte ausgestattet ist, welche halbautomatisch um die Armierungseisen gelegt und so gebogen werden, dass sich an den Enden der Bindedrähte Haken ausbilden, mit denen die Armierungseisen zusammengeklammert und aneinander gezogen werden können. Das in der Patentschrift beschriebene Bindewerkzeug weist jedoch keine überzeugenden Vorteile gegenüber den übrigen bisher beschriebenen Bindewerkzeugen auf. Die vorliegende Erfindung stellt sich nun die Aufgabe, ein Bindewerkzeug der eingangs erwähnten Art zu schaffen, welches universeller einsetzbar ist.In addition, US Pat. No. 5,542,228 describes a binding tool that is equipped with a magazine for a large number of two-legged binding wires, which are placed semi-automatically around the reinforcing bars and bent so that hooks are formed at the ends of the binding wires, with which the reinforcing bars clamped together and can be pulled together. The binding tool described in the patent, however, has no convincing advantages over the other binding tools described so far. The object of the present invention is to create a binding tool of the type mentioned at the outset, which can be used more universally.
Die Aufgabe wird mit Hilfe der erfindungsgemässen Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved with the aid of the features of claim 1 according to the invention. Advantageous developments of the invention are the subject of the dependent claims.
Das vorgeschlagene Bindewerkzeug zur Montage von Bindedrähten umfasst eine Triebwelle mit Steilgewinde, welche an einem Ende eine eine Fixiereinrichtung aufweisende Haltevorrichtung zur Aufnahme der beiden Endabschnitte eines Bindedrahtes trägt. Die Triebwelle kann durch Auf- und/oder Abbewegung eines zum Steilgewinde passenden Handgriffs, welcher auf der Innenseite mit einem Mutter-Gewinde versehen ist, in Drehbewegung versetzt werden. Die vorgeschlagene Haltevorrichtung kann in drei Varianten ausgeführt werden.The proposed binding tool for assembling binding wires comprises a drive shaft with steep thread, which carries at one end a holding device having a fixing device for receiving the two end sections of a binding wire. The drive shaft can be rotated by moving up and / or down a handle matching the steep thread, which is provided with a nut thread on the inside. The proposed holding device can be implemented in three variants.
Die Haltevorrichtung ist derart ausgestaltet, dass ein ösenloser Bindedraht und auch ein Bindedraht ohne Verdickungen an seinen Endabschnitten in die Haltevorrichtung eingelegt werden kann und dort fixiert wird.The holding device is designed in such a way that an eyelet-free binding wire and also a binding wire can be inserted into the holding device without thickening at its end sections and fixed there.

Haltevorrichtung gemäss Fig. 4b. Das vorgeschlagene Bindewerkzeug ist in Fig. 1a abgebildet, eine detailliertere Ansicht der Haltevorrichtung 1 zur Hervorhebung der wechselseitigen Orientierung der Einzelteile zeigt Fig. 1b. Das vorgeschlagene Bindewerkzeug besteht aus einer Triebwelle 3 mit Steilgewinde 2. Die Triebwelle 3 trägt an einem Ende eine Bindedraht-Haltevorrichtung 1 , welche mittels einer Fixiereinrichtung zur gesicherten Aufnahme der Endabschnitte eines ösenlosen oder an seinen Endabschnitten nicht verdickten Bindedrahtes dient. Die Triebwelle 3 wird manuell durch die Bewegung eines zum Steilgewinde 2 passenden Handgriffs 4 (mit Mutter-Gewinde auf Innenseite) in Drehbewegung gesetzt. Die Haltevorrichtung 1 besteht aus einem Grundkörper mit der aussenseitig angebrachten Eckbacke 8 und der Haltebacke 10. Zwischen diesen beiden Backen 8 und 10 befindet sich der Halteschlitz 9 mit einem birnenförmigen Querschnitt. In der Mitte befindet sich der Mittelschlitz 6, an dessen Mittelbacken 5 bildenden Seitenwänden zwei gegeneinander versetzte Schneidkanten 11 als Fixiereinrichtung angebracht sind. Diese Schneidkanten 11 sind derart schräg angebracht, dass ein darin verkeiltes Drahtende noch weiter in den Schlitz hinunter gezogen wird, wenn Zugkräfte auf dieses Drahtende wirken.Holding device according to Fig. 4b. The proposed binding tool is shown in Fig. 1a, a more detailed view of the holding device 1 to emphasize the mutual orientation of the individual parts is shown in Fig. 1b. The proposed binding tool consists of a drive shaft 3 with steep thread 2. The drive shaft 3 carries at one end a binding wire holding device 1, which is used by means of a fixing device for securely receiving the end sections of an eyelet-free binding wire or one which is not thickened at its end sections. The drive shaft 3 is manually rotated by the movement of a handle 4 (with a nut thread on the inside) that matches the steep thread 2. The holding device 1 consists of a base body with the corner jaw 8 and the holding jaw 10 attached to the outside. Between these two jaws 8 and 10 there is the holding slot 9 with a pear-shaped cross section. In the middle there is the central slot 6, on the side walls forming the central jaws 5 two cutting edges 11 offset from one another are attached as a fixing device. These cutting edges 11 are attached obliquely such that a wire end wedged therein is pulled further down into the slot when tensile forces act on this wire end.
Die Fixierung des Drahtes an der Haltevorrichtung geschieht dadurch, dass mit einer Hand das Bindewerkzeug gehalten wird, während mit der andern Hand der Bindedraht mit dem ersten Ende in den Halteschlitz 9 gelegt wird. Nun wird der freie Bereich dieses ersten Endes des Bindedrahtes in den zwischen der Mittelbacke 5 und der einen Eckbacke 8 angeordneten Seitenschlitz 7 gebogen, welcher gegen unten leicht konusförmig zuläuft. Wird der Bindedraht am anderen freien Ende nun vom Bindewerkzeug weggezogen, verkeilt sich das fixierte Ende des Bindedrahtes aufgrund der konusförmigen Verjüngung im Seitenschlitz 7, wodurch der Bindedraht in der Haltevorrichtung 1 verankert wird und fest in der Haltevorrichtung 1 sitzen bleibt. Das andere freie Ende des Bindedrahtes wird nun um die zu verbindenden Armierungseisen herumgeführt und anschliessend in den Mittelschlitz 6 eingelegt. Beim Einlegen dieses Endes des Bindedrahtes in den Mittelschlitz 6 wird der Bindedraht an den Stellen, an denen er mit den Schneidkanten 11 in Berührung kommt, verformt und leicht angeritzt, so dass er gegen ein unbeabsichtigtes Herausrutschen (beziehungsweise Herausziehen) aus dem Mittelschlitz 6 gesichert ist. Diese Sicherung geschieht dadurch, dass der Draht, welcher sich zuerst im oberen Teil des Schlitzes befindet, durch die schrägen Schneidkanten 11 nach vorne unten geführt wird und dadurch bei Zug immer weiter in den Schlitz hineingezogen wird.The wire is fixed to the holding device in that the binding tool is held with one hand, while the other end of the binding wire is placed in the holding slot 9. Now the free area of this first end of the binding wire is bent into the side slot 7 arranged between the central jaw 5 and the one corner jaw 8, which tapers slightly conically towards the bottom. If the binding wire at the other free end is now pulled away from the binding tool, the fixed end of the binding wire is wedged due to the conical taper in the side slot 7, as a result of which the binding wire is anchored in the holding device 1 and remains firmly seated in the holding device 1. The other free end of the The binding wire is now guided around the reinforcing bars to be connected and then inserted into the central slot 6. When this end of the binding wire is inserted into the central slot 6, the binding wire is deformed and slightly scored at the points where it comes into contact with the cutting edges 11, so that it is secured against inadvertent slipping out (or pulling out) from the central slot 6 , This securing takes place in that the wire, which is first in the upper part of the slot, is guided forward and downward through the oblique cutting edges 11 and is thereby drawn further and further into the slot when it is pulled.
Beim Einlegen des Bindedrahtes in die Haltevorrichtung 1 sollte sich der Handgriff 4 in der Nähe der Haltevorrichtung 1 befinden. Ist der Bindedraht mit beiden Enden eingelegt, wird der Handgriff 4 (welcher auf der Innenseite ein Mutter-Gewinde aufweist) auf der Triebwelle 3 von der Haltevorrichtung 1 weggezogen. Da die Triebwelle 3 ein Steilgewinde 2 aufweist und der Handgriff 4 in der Hand festgehalten wird, d. h. sich nicht dreht, muss sich die Triebwelle 3 und damit die Haltevorrichtung 1 samt Bindedraht drehen. Die beiden Enden des Bindedrahtes werden dadurch miteinander verdrillt, wodurch der Bindedraht um die Armierungseisen fest zusammengezogen wird und dadurch die Armierungseisen fest zusammenbindet. Nachdem der Handgriff 4 zum oberen Ende der Triebwelle 3 gezogen worden ist, können die miteinander verdrillten Enden des Bindedrahtes leicht durch eine einfache Handbewegung aus der Haltevorrichtung 1 herausgeschwenkt werden. Damit das Bindewerkzeug auch für Linkshänder bedienbar wird, kann die Haltevorrichtung spiegelsymmetrisch gebaut werden, d. h. die Vorrichtung mit Seitenschlitz 7 und dem Halteschlitz 9 kommt dann auf die andere Seite der Haltevorrichtung 1 zu liegen, wie dies in Fig. 2a und b gezeigt wird. In Fig. 2 wird dabei eine Ausführungsform gezeigt, welche sowohl für Rechts- wie für Linkshänder geeignet ist, indem auf beiden Seiten der Haltevorrichtung je ein Seitenschlitz 7 und ein Halteschlitz 9 mit der entsprechenden Zusatz-Eckbacke 12 vorgesehen sind. Damit erreicht man, dass wahlweise entweder von den Schlitzen 7 und 9 auf der rechten oder linken Seite Gebrauch gemacht werden kann, je nachdem, ob man Rechts- oder Linkshänder ist.When inserting the binding wire in the holding device 1, the handle 4 should be in the vicinity of the holding device 1. If the binding wire is inserted with both ends, the handle 4 (which has a nut thread on the inside) on the drive shaft 3 is pulled away from the holding device 1. Since the drive shaft 3 has a steep thread 2 and the handle 4 is held in the hand, ie does not rotate, the drive shaft 3 and thus the holding device 1 together with the binding wire must rotate. As a result, the two ends of the binding wire are twisted together, as a result of which the binding wire is pulled tightly around the reinforcing bars and thereby firmly ties the reinforcing bars together. After the handle 4 has been pulled toward the upper end of the drive shaft 3, the twisted ends of the binding wire can easily be pivoted out of the holding device 1 by a simple hand movement. So that the binding tool can also be used by left-handers, the holding device can be constructed mirror-symmetrically, ie the device with side slot 7 and holding slot 9 then comes to rest on the other side of the holding device 1, as is shown in FIGS. 2a and b. 2 shows an embodiment which is suitable for both right-handed and left-handed users is suitable in that a side slot 7 and a holding slot 9 with the corresponding additional corner jaw 12 are provided on both sides of the holding device. This means that either slots 7 and 9 on the right or left side can be used, depending on whether you are right-handed or left-handed.
Fig. 1 und 2 zeigen die 1. Variante, bei welcher die beiden Enden des Bindedrahtes in verschieden gebauten Schlitzen untergebracht werden. Bei dieser Variante gibt es somit Ausführungsformen, welche nur für Rechtshänder, nur für Linkshänder oder für beide vorgesehen sind.1 and 2 show the 1st variant, in which the two ends of the binding wire are accommodated in differently constructed slots. In this variant, there are embodiments which are only intended for right-handers, only for left-handers or for both.
Fig. 3a und 3b stellen die zweite Variante des vorgeschlagenen Bindewerkzeuges dar. Diese vorteilhafte Weiterentwicklung ist dadurch gekennzeichnet, dass sie nur einen Mittelschlitz 6 aufweist, in welchen zuerst ein Ende des Bindedrahtes und später, nachdem der Bindedraht um die zu verbindenden Armierungseisen gelegt worden ist, auch das zweite Drahtende eingelegt wird. Vorteil dieser Variante ist die Bedienbarkeit durch Rechts- wie auch Linkshänder, sowie der geringere Fertigungsaufwand.3a and 3b represent the second variant of the proposed binding tool. This advantageous further development is characterized in that it has only one central slot 6, in which first one end of the binding wire and later after the binding wire has been placed around the reinforcing bars to be connected , the second wire end is also inserted. The advantage of this variant is that it can be operated by right-handed and left-handed people, as well as the lower manufacturing effort.
Fig. 4 zeigt die dritte Variante des vorgeschlagenen Bindewerkzeuges. Diese weitere vorteilhafte Weiterentwicklung des vorgeschlagenen Bindewerkzeuges ist dadurch gekennzeichnet, dass die Haltevorrichtung zwei gleichartige Schlitze mit je zwei gegenüberliegenden Schneiden aufweist. Die beiden Universalschlitze 13 verjüngen sich gegen die Grundfläche der Haltevorrichtung. Der Bindedraht wird dabei zuerst in einen der beiden Universalschlitze 13 gelegt, wo er durch die die Fixiereinrichtung bildenden Schneidkanten 14 angeritzt und so fixiert wird. Nachdem der Draht um die Armierungseisen gelegt worden ist, wird das andere Drahtende in den noch freien Schlitz gelegt, wo er ebenfalls durch die beiden Schneidkanten 14 fixiert wird. Auch diese Variante kann sowohl von Links- wie auch von Rechtshändern bedient werden.Fig. 4 shows the third variant of the proposed binding tool. This further advantageous further development of the proposed binding tool is characterized in that the holding device has two identical slots, each with two opposing cutting edges. The two universal slots 13 taper against the base of the holding device. The binding wire is first placed in one of the two universal slots 13, where it is scored and thus fixed by the cutting edges 14 forming the fixing device. After the wire has been placed around the reinforcing bars, the other end of the wire is placed in the still free slot, where it is also fixed by the two cutting edges 14 becomes. This variant can also be operated by left-handed as well as right-handed people.
Beim vorgeschlagenen Bindewerkzeug handelt es sich um ein sehr einfaches Werkzeug, welches gegenüber den in der Praxis und gegenüber den in der Patentliteratur beschriebenen Bindewerkzeugen deutliche Vorteile aufweist. Es ersetzt die alten, bekannten Geräte, welche vorne einen Haken besitzen und für welche man nur Drähte mit Ösen verwenden konnte. Mit diesem neuen Werkzeug lässt sich somit wie mit den alten arbeiten. Der grosse Unterschied liegt jedoch darin, dass man für dieses Gerät keine Drähte mehr mit Ösen braucht, sondern mit den einfachen, ösenlosen Drähten arbeiten kann. Das Einlegen und Fixieren des Bindedrahtes in der Haltevorrichtung erfolgen leicht und sicher. Ein besonderer Vorteil des vorgeschlagenen Bindewerkzeugs ist die Möglichkeit, gerade Bindedrähte ohne geschlaufte Enden und ohne Verdickungen aufweisende Enden und mit beliebigem Querschnitt zu verwenden. Dies hat den Vorteil, dass die Bindedrähte viel einfacher hergestellt werden können und dadurch auch mit viel kleineren Fertigungskosten herstellbar sind, indem sie einfach ab Rolle in einer bestimmten Länge geschnitten werden können. Aber auch die Lagerung dieser Bindedrähte ist einfacher, zudem lassen sie sich auch auf dem Bau viel einfacher aus einer entsprechenden Vorratsdose entnehmen. Im übrigen wird vorzugsweise ein Draht verwendet, der kunststoffummantelt ist. Die Kunststoffummantelung wird durch die Schneidkanten 11 eingeritzt, der Bindedraht wird so fixiert. Da die Herstellung von geschlauften und geschweissten Bindedrähten im Verhältnis zu ungeformten Drähten relativ kostenintensiv ist, ergibt sich durch die Verwendung des vorgeschlagenen Bindewerkzeugs für gerade Bindedrähte ohne Ösen oder Verdickungen ein signifikanter Kostenvorteil. Da zudem das Arbeiten mit dem Bindedraht ohne Ösen deutlich leichter ausfällt als bei solchen mit Ösen, kann bei der vorgeschlagenen Lösung das Einlegen in das Bindewerkzeug und das Verdrillen ohne Ablegen der Arbeitshandschuhe erfolgen.The proposed binding tool is a very simple tool, which has clear advantages over the binding tools described in practice and over the binding tools described in the patent literature. It replaces the old, well-known devices, which have a hook at the front and for which you could only use wires with eyelets. With this new tool you can work like with the old ones. The big difference, however, is that you no longer need wires with eyelets for this device, but can work with simple, eyelet-free wires. Inserting and fixing the binding wire in the holding device is easy and safe. A particular advantage of the proposed binding tool is the possibility of using straight binding wires without looped ends and without thickened ends and with any cross section. This has the advantage that the binding wires can be produced much more easily and can therefore also be produced at much lower production costs by simply cutting them to a certain length from the reel. But the storage of these binding wires is also easier, and they are also much easier to remove from a corresponding storage jar during construction. For the rest, a wire is preferably used, which is coated with plastic. The plastic sheathing is scratched through the cutting edges 11, the binding wire is fixed in this way. Since the production of looped and welded binding wires is relatively expensive in comparison to unshaped wires, the use of the proposed binding tool for straight binding wires without eyelets or thickening results in a significant cost advantage. Since working with the binding wire without eyelets is much easier than with those with eyelets, the proposed solution can be inserted into the binding tool and twisted without removing the work gloves.
Schliesslich eignet sich das vorgeschlagene Bindewerkzeug nicht nur zum Verbinden von Armierungseisen, sondern generell zur Verbindung von zwei oder mehreren aufeinander- oder nebeneinanderliegenden Gegenständen. Dieses Bindewerkzeug kann beispielsweise auch zum Schliessen von Säcken oder aber auch zum Fixieren von Elektrokabeln eingesetzt werden. Finally, the proposed binding tool is not only suitable for connecting reinforcing bars, but generally for connecting two or more objects lying one on top of the other or next to one another. This binding tool can also be used, for example, to close bags or to fix electrical cables.
