Abstract

1. Levered pliers, in particular bolt cutters, with one pair each of double-armed cutting-jaw (1, 2) and hand levers (8, 9) which in each case are articulated on one another and not cross in the area of the articulated points (5, 12), and with connecting articulations (10, 11) between the ends of the cutting-jaw and hand levers facing one another, characterized in that, in an area near the cutting-jaw levers (1, 2), the hand levers (8, 9) are in each case bent twice at least in such a way that, in this area (14a, 14b), the hand levers cross one another twice (18, 19) in the closed condition of the pliers.

Description

Die Erfindung betrifft eine hebelübersetzte Zange, insbesondere Bolzenschneider mit je einem Paar zweiarmiger Schneidbacken- und Handhebel, die jeweils aneinander angelenkt sind und im Bereich der Anlenkstellen sich nicht kreuzen, und mit Verbindungsgelenken zwischen den einander zugewandten Enden der Schneidbacken- und Handhebel.The invention relates to a lever-translated pliers, in particular bolt cutters, each with a pair of two-armed die jaws and hand levers, which are each articulated to one another and do not cross in the region of the articulation points, and with connecting joints between the mutually facing ends of the die jaws and hand levers.

Die bekannten Bolzenschneider, wie sie z.B. aus der DE-OS 32 21 072 bekannt sind, weisen an die Schneidbacken angelenkte Handhebel auf, die bei weit geöffneter Zange um die Anlenkstelle der Handhebel so weit auseinanderbewegt werden, daß sie zwischen sich einen Winkel von 90 Grad oder mehr bilden und hierdurch mit den Schneidbacken nur so weit in Öffnungen, insbesondere Zwischenräumen, einer oberen Bewehrungsschicht eingesteckt werden, bis die vorderen Außenseiten der Handhebel auf dem Öffnungsrand aufliegen. Damit kann in den meisten Fällen eine darunter liegende Matte oder Bewehrung durch die Schneiden nicht erreicht werden. Muß dennoch eine tiefer liegende Bewehrung oder Bewehrungsmatte geschnitten werden, so wird häufig die Öffnung in der oberen Bewehrung zwischen zwei Bewehrungsstäben durch zusätzliche Schnitte vergrößert, so daß die obere Bewehrung geschwächt wird. Darüber hinaus ist dies ein zusätzlicher Arbeitsaufwand.The known bolt cutters, as are known, for example, from DE-OS 32 21 072, have articulated hand levers on the cutting jaws, which are moved so far apart with the pliers around the articulation point of the hand levers that they have an angle of 90 degrees between them or more and are thereby inserted with the cutting jaws only so far into openings, in particular spaces, of an upper reinforcement layer until the front outer sides of the hand levers rest on the opening edge. In most cases, this means that an underlying mat or reinforcement cannot be reached by the cutting edges will. If a lower-lying reinforcement or reinforcement mat still has to be cut, the opening in the upper reinforcement between two reinforcement bars is often enlarged by additional cuts, so that the upper reinforcement is weakened. In addition, this is an additional workload.

Aufgabe der Erfindung ist es, eine Zange der eingangs genannten Art so zu verbessern, daß durch enge Öffnungen zu schneidende Teile erreichbar sind, die gegenüber der Öffnung tiefer liegen als die Länge der zweiarmigen Schneidbacken.The object of the invention is to improve pliers of the type mentioned in such a way that parts to be cut can be reached through narrow openings which are lower than the length of the two-armed cutting jaws relative to the opening.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in einem den Schneidbackenhebeln nahen Bereich die Handhebel jeweils mindestens derart zweifach abgebogen sind, daß in diesem Bereich die Handhebel im geschlossenen Zustand der Zange einander zweifach kreuzen.This object is achieved in that in a region close to the cutting jaw levers the hand levers are bent at least twice in such a way that in this region the hand levers cross each other twice in the closed state of the pliers.

Durch diese Ausführung des vorderen Bereichs der Handhebel kann dieser Bereich als Verlängerung der Schneidbacken zusätzlich in die Öffnung eingebracht werden, so daß auch sehr tief liegende Bewehrungen oder zu schneidende Drähte erreichbar sind. Die Zange ist leicht handhabbar und einfach in der Herstellung. Es entsteht kein zusätzlicher Arbeitsaufwand, und eine Vergrößerung der oberen Öffnung, und damit Schwächung einer oberen oder vorderen Bewehrung, entfällt.As a result of this design of the front area of the hand lever, this area can also be introduced into the opening as an extension of the cutting jaws, so that even very deep reinforcements or wires to be cut can be reached. The pliers are easy to handle and simple to manufacture. There is no additional work involved, and there is no need to enlarge the upper opening and thus weaken an upper or front reinforcement.

Besonders vorteilhaft ist es hierbei, wenn die ersten Bereiche der Handhebel, die den Schneidbackenhebeln am nächsten sind und die bei geschlossener Zange den den Schneidbackenhebeln nächsten Kreuzungspunkt bilden, bei weit geöffneter Zange zueinander etwa parallel liegen. Auch wird vorteilhafterweise vorgeschlagen, daß die ersten Bereiche der Handhebel bei weit geöffneter Zange im etwa parallelen Zustand von Außenseite zu Außenseite eine Breite bilden, die etwa gleich der Breite der Schneidbackenhebel von Außenseite zu Außenseite ist. Auch sollte an den ersten Bereich der Handhebel ein zweiter Bereich der Handhebel anschließen, der bei geschlossener Zange den zweiten Kreuzungspunkt bildet. Hierbei kann ein erster und zweiter Berei-eh der Handhebel zueinander abgebogen sein und miteinander einen dem anderen Handhebel zugekehrten Innenwinkel bilden, der 60 bis 120 Grad, insbesondere 80 bis 100 Grad beträgt.It is particularly advantageous here if the first areas of the hand levers, which are closest to the die jaw levers and which form the point of intersection closest to the die jaw levers when the pliers are closed, are approximately parallel to one another when the pliers are wide open. It is also advantageously proposed that the first areas of the hand levers approximately open when the pliers are wide open parallel state from the outside to the outside form a width which is approximately equal to the width of the cutting jaw lever from the outside to the outside. A second area of the hand lever should also connect to the first area of the hand lever, which forms the second crossing point when the pliers are closed. In this case, a first and second region of the hand lever can be bent toward one another and together form an inner angle facing the other hand lever, which is 60 to 120 degrees, in particular 80 to 100 degrees.

Ferner wird vorteilhafterweise vorgeschlagen, daß bei geschlossener Zange die einander zweifach kreuzenden Bereiche einander seitlich teilweise überdecken. Alternativ kann aber auch bei geschlossener Zange der zweifach kreuzende Bereich des ersten Handhebels in einem Längsschlitz des zweiten Handhebels einliegen, so daß die Handhebel in einer ähnlichen Weise ineinanderdringen wie dies bereits bei Wasserpumpenzangen mit durchgestecktem Gleitgelenk bekannt ist.Furthermore, it is advantageously proposed that when the pliers are closed, the regions which cross each other twice partially overlap one another laterally. Alternatively, the double-crossing area of the first hand lever can also lie in a longitudinal slot of the second hand lever when the pliers are closed, so that the hand levers interlock in a manner similar to that which is already known for water pump pliers with an inserted sliding joint.

Vorzugsweise wird vorgeschlagen, daß bei geschlossener Zange die Anschläge in Höhe des zweiten Kreuzungspunktes am zweiten Bereich anschlagen. Hierdurch werden besonders einfach zu gestaltende und sicher arbeitende Anschläge geschaffen.It is preferably proposed that when the pliers are closed, the stops strike the second region at the level of the second crossing point. This creates particularly easy to design and safe working stops.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung bei nicht vollständig durchzeichneten Handgriffen in einer Vorderansicht dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing in a not completely drawn handles in a front view and is described in more detail below.

Der Bolzenschneider besteht im wesentlichen aus zwei zweiarmigen Hebelpaaren, die untereinander und aneinander angelenkt sind, ohne sich zu kreuzen. Die zweiarmigen Schneidbackenhebel 1, 2 weisen an ihren freien Enden zwischen den vorderen Backen Schneiden 3, 4 auf, die im Beißschnitt aufeinander liegen. Die Schneidbackenhebel 1, 2 sind durch ein einziges mittiges Gelenk 5 direkt angelenkt, wobei die Schneiden seitlich liegen, oder aber die Schneidbackenhebel sind auf beiden Flachseiten an je einer Lasche durch zwei Schraubenzapfen angelenkt, wie dies die deutsche Offenlegungsschrift P 32 21 072 zeigt, so daß die Schneiden in Achsrichtung der Zange liegen.The bolt cutter essentially consists of two pairs of levers, which are articulated to each other and to each other without crossing. The two-armed cutting jaw levers 1, 2 have at their free ends between the front jaws cut 3, 4, which lie on each other in the bite cut. The cutting jaw levers 1, 2 are articulated directly by a single central joint 5, the cutting edges being on the side, or the cutting jaw levers are articulated on both flat sides on one tab each by two screw journals, as is shown in German Offenlegungsschrift P 32 21 072, so that the cutting edges are in the axial direction of the pliers.

Auf den den Schneiden 3, 4 abgewandten Seiten sind die Schneidbackenhebel 1, 2 an zweiarmigen Handhebeln 8, 9 über Verbindungsgelenke 10, 11 mit Gelenkzapfen, insbesondere Schraubzapfen, angelenkt. Nahe der Verbindungsgelenke 10, 11 sind die beiden Handhebel 8, 9 durch einen Gelenkzapfen, insbesondere Schraubzapfen mit z.B. Exzenterhub, aneinander angelenkt. An diesem Verbindungsgelenk 12 der beiden Handhebel kann in einer nicht dargestellten Ausführung eine Stellschraube angreifen, die im ersten Handhebel gelagert ist und die Verbindung zwischen dem ersten Handhebel und dem Verbindungsgelenk bzw. dem zweiten Handhebel darstellt. Die Stellschraube ist in einer Bohrung des ersten Handhebels längsverschieblich gelagert und durch Stellmuttern in beide Verschiebungsrichtungen gehalten.On the sides facing away from the cutting edges 3, 4, the cutting jaw levers 1, 2 are articulated on two-armed hand levers 8, 9 via connecting joints 10, 11 with pivot pins, in particular screw pins. Near the connecting joints 10, 11, the two hand levers 8, 9 are connected by a pivot pin, in particular a screw pin with e.g. Eccentric stroke, hinged together. In an embodiment (not shown), an adjusting screw, which is mounted in the first hand lever and represents the connection between the first hand lever and the connecting joint or the second hand lever, can act on this connecting joint 12 of the two hand levers. The set screw is mounted in a bore of the first hand lever so as to be longitudinally displaceable and is held in both directions of displacement by adjusting nuts.

Die Handhebel 8, 9 bestehen im Bereich der Gelenke 10, 11 und 12 aus geschmiedeten Stücken, auf die Rohre 16, 17 zur Verlängerung und Bildung der Griffbereiche aufgeschoben sind. Diese geschmiedeten Zwischenstücke beider Handhebel bilden damit die Bereiche 14a, 14b, die den Schneidbacken am nächsten sind und mit ihren vorderen Enden über die Gelenke 10, 11 mit den Schneidbacken 1, 2 verbunden sind. Hierbei sind diese Bereiche 14a, 14b so ausgeführt, daß im geschlossenen Zustand der Zange diese Bereiche einander zweifach in den Punkten 18 und 19 kreuzen, ohne dort befestigt oder angelenkt zu sein.The hand levers 8, 9 consist of forged pieces in the area of the joints 10, 11 and 12, onto which tubes 16, 17 are pushed to extend and form the grip areas. These forged intermediate pieces of both hand levers thus form the regions 14a, 14b which are closest to the cutting jaws and are connected with their front ends to the cutting jaws 1, 2 via the joints 10, 11. Here, these areas 14a, 14b are designed such that, when the pliers are closed, these areas cross each other twice in points 18 and 19 without being fastened or articulated there.

Von den Verbindungsgelenken 10, 11 ausgehend sind diese Bereiche 14a, 14b kurz hinter dem Verbindungsgelenk 12 jeweils nach innen um etwa einen Winkel von α = 450 einwärts umgebogen (erste Abbiegung 20), um dann einen ersten geraden Bereich 21 jeweils zu bilden, die sich etwa mittig kreuzen und damit den ersten Kreuzungspunkt 18 bilden. Dieser erste Bereich 21 beider Handhebel endet bei einer zweiten nach einseits gekehrten Abbiegung (zweite Abbiegung 22), die in einem Winkel β von etwa 90° ausgeführt ist. Dieser Winkel kann in einem Bereich von 60 bis 120°, insbesondere 80 bis 100°, liegen.Starting from the joint connectors 10, 11 are these portions 14a, 14b short inwardly to an angle of approximately α = 45 0 inwardly bent behind the connecting link 12 in each case (first bend 20) in order to then form a first straight portion 21, respectively, the intersect approximately in the middle and thus form the first crossing point 18. This first area 21 of both hand levers ends at a second bend which is turned towards one side (second bend 22) and is made at an angle β of approximately 90 °. This angle can be in a range from 60 to 120 °, in particular 80 to 100 °.

Hinter dieser zweiten Abbiegung 22 liegt ein zweiter gerader Bereich 23 der Handhebel, die wiederum einander im Punkt 19 kreuzen. Am Ende dieser beiden zweiten Bereiche 23 der Handhebel sind die Rohre 16, 17 in einem Winkel von α - ca. 35° aufgesteckt.Behind this second turn 22 there is a second straight region 23 of the hand levers, which in turn cross each other at point 19. At the end of these two second regions 23 of the hand levers, the tubes 16, 17 are plugged on at an angle of α - approximately 35 °.

Die den Schneidbacken nahen Bereiche 14a, 14b der Handhebel 8, 9 bilden somit zwischen den aufgesteckten Rohren 16, 17 und den Verbindungsgelenken 10, 11 bzw. dem Verbindungsgelenk 12 zwei winkelförmig abgeknickte Bereiche, wobei die Knickung jeweils nach innen in entgegengesetzten Richtungen erfolgt, so daß sich diese Bereiche zweifach kreuzen und die Abbiegestellen 22 außen liegen, wenn die Zange geschlossen ist. In der geschlossenen Stellung umschließen diese Bereiche in Höhe der Abbiegungen 22 eine etwa rechteckförmige, insbesondere etwa quadratische Öffnung 24. Ist dagegen die Zange weit geöffnet, so liegen die Bereiche 21 zueinander im wesentlichen parallel, wobei die Außenseiten beider Bereiche 21 in ihrer Breite B etwa der Breite C der Außenseiten der Schneidbackenhebel 1, 2 sind.The areas 14a, 14b of the hand levers 8, 9 near the cutting jaws thus form two angularly bent areas between the attached pipes 16, 17 and the connecting joints 10, 11 or the connecting joint 12, the kinking taking place inwards in opposite directions, so that these areas intersect twice and the turning points 22 are outside when the pliers are closed. In the closed position, these areas enclose an approximately rectangular, in particular approximately square, opening 24 at the level of the bends 22. On the other hand, if the pliers are wide open, the areas 21 are essentially parallel to one another, the width B of the outer sides of the areas 21 being approximately the width C of the outer sides of the cutting jaw levers 1, 2.

Die Zange kann also im geöffneten Zustand um die Länge der beiden ersten Bereiche 21 tiefer in eine Öffnung gesteckt werden als eine übliche Zange.The pliers can thus be inserted into the opening by the length of the first two regions 21 deeper than a conventional pliers.

Die geschmiedeten Zwischenstücke beider Handhebel weisen in den Bereichen 23 unterhalb der Kreuzungsstelle 19 Anschläge 25, 26 auf, die bei geschlossener Zange jeweils am gegenüberliegenden Handhebel in Höhe der Kreuzungsstelle 19 anschlagen.The forged intermediate pieces of the two hand levers have stops 25, 26 in the areas 23 below the crossing point 19, each of which strikes the opposite hand lever at the level of the crossing point 19 when the pliers are closed.
