Description

Gebiet der ErfindungField of invention

Die vorliegende Erfindung betrifft einen Hackenspanner, umfassend einen Spannhaken mit einem Hakenelement, wobei der Spannhaken zur Durchführung durch eine Öffnung eines zu spannenden Bauteils geeignet ist.The present invention relates to a hook clamp, comprising a clamping hook with a hook element, the clamping hook being suitable for passing through an opening of a component to be clamped.

Stand der TechnikState of the art

Derartige Hackenspanner sind an sich bereits bekannt und werden insbesondere im Automobilbau verwendet, beispielsweise um ein Karosseriebauteil im Zuge der Fahrzeugfertigung gegen ein weiteres Fahrzeugbauteil zu spannen.Such hook clamps are already known per se and are used in particular in automobile construction, for example in order to clamp a body component against another vehicle component in the course of vehicle production.

Das zu verspannende Bauteil muss dabei eine Öffnung aufweisen, durch welche ein mit einem Haken versehener Spannhaken des Hackenspanners hindurchgeführt wird, so dass dann mittels des Hakens das Bauteil in Richtung zum Hackenspanner (nach "hinten") und insbesondere in Richtung zu einem zwischen dem Bauteil und einem Gehäuse des Hackenspanners angeordneten weiteren Bauteil gezogen werden kann.The component to be clamped must have an opening through which a hook of the hook clamp of the hook clamp is passed, so that the hook then moves the component in the direction of the hook clamp ("backwards") and in particular in the direction of one between the component and a further component arranged in a housing of the hoe tensioner can be pulled.

Die Hackenspanner können auch so ausgebildet sein, dass beim Ziehen des zu spannenden Bauteils gleichzeitig das Hakenelement in Richtung zum Haken (nach "unten") bewegt wird, so dass der Haken während der Ziehbewegung besser in das zu spannende Bauteil eingreifen und dieses mitnehmen kann.The hook clamps can also be designed so that when the component to be clamped is pulled, the hook element is simultaneously moved towards the hook ("down"), so that the hook can better engage the component to be clamped during the pulling movement and take it with it.

Beispielsweise offenbart die EP 1 391 266 A2 einen Zentrierspanner für die zentrierte Festlegung eines zu bearbeitenden Bauteiles, bestehend aus einem über einem aus Haken und Hakenarm gebildeten Spannhaken des Spannerantriebes angeordneten, auf einer Adapterplatte sitzenden Zentrierdorn mit einem Durchgriffsschlitz für den Spannhaken, wobei sich an die Spannhakenflanke anlegende Schutzelemente zur Verhinderung von Fremdkörpereintritt in die Spannhakendurchgriffsöffnung der Adapterplatte vorgesehen sind.For example, the EP 1 391 266 A2 a centering clamp for the centered fixing of a component to be machined, consisting of a centering pin located on an adapter plate and arranged over a clamping hook of the clamp drive formed from a hook and hook arm, with a slot for the clamping hook, with protective elements resting on the clamping hook flank to prevent foreign bodies from entering the clamping hook opening of the adapter plate are provided.

Dieser bekannte Zentrierspanner weist einen Zentrierdorn auf, der durch das zu spannende Bauteil geführt werden muss, so dass das Bauteil eine entsprechend große Öffnung benötigt. Außerdem ist der Haken des Spannhakens in dieser Ausführung nur relativ wenig in Querrichtung bewegbar, da sein Weg durch den Zentrierdorn begrenzt ist. Daher ist das Werkzeug für größere Bauteiltoleranzen weniger geeignet.This known centering clamp has a centering mandrel which has to be passed through the component to be clamped, so that the component requires a correspondingly large opening. In addition, the hook of the clamping hook can only be moved relatively little in the transverse direction in this embodiment, since its path is limited by the centering pin. The tool is therefore less suitable for larger component tolerances.

Aus der DE 20 2015 008 208 U1 ist ein Zentrierspanner nach dem Oberbegriff von Anspruch 1 bekannt.From the DE 20 2015 008 208 U1 a centering clamp according to the preamble of claim 1 is known.

Zusammenfassung der ErfindungSummary of the invention

Es ist eine Aufgabe der Erfindung, einen Hackenspanner in dieser Hinsicht zu verbessern und insbesondere einen alternativen Hackenspanner anzugeben, der auch bei größeren Bauteiltoleranzen eingesetzt werden kann, eine hohe Zugkraft ermöglicht und dabei lediglich eine kleine Durchtrittsöffnung am zu verspannenden Bauteil voraussetzt.It is an object of the invention to improve a hook clamp in this regard and in particular to provide an alternative hook clamp which can also be used with larger component tolerances, enables a high tensile force and only requires a small opening on the component to be clamped.

Die Lösung der Aufgabe erfolgt durch einen Hackenspanner, umfassend einen Spannhaken mit einem Hakenelement, wobei der Spannhaken zur Durchführung durch eine Öffnung eines zu spannenden Bauteils ausgebildet ist, ferner umfassend einen Aktuator, wobei der Spannhaken mittels des Aktuators von einer geöffneten Stellung in einer Ziehrichtung in eine geschlossene Stellung gezogen werden kann, wobei das Hakenelement in der geschlossenen Stellung, zusätzlich zum Versatz in Ziehrichtung, in Richtung zum Hakenende des Hakenelements, i.e. in eine Hakenrichtung, versetzt ist, wobei der Spannhaken einen ersten Schenkel umfasst, wobei an einem freien Ende des ersten Schenkels das Hakenelement ausgebildet ist, wobei der Spannhaken einen in einem Winkel zum ersten Schenkel angeordneten zweiten Schenkel umfasst, wobei an dem zweiten Schenkel in einem Anlenkpunkt der Aktuator zum Ziehen des Spannhakens in die geschlossene Stellung angelenkt ist, wobei der Spannhaken an einer Führungsposition zwischen dem Anlenkpunkt und dem Hakenelement in einem Langloch in einer Richtung parallel zur Ziehrichtung verschiebbar gelagert ist, wobei der Spannhaken mittels eines Federelements an einer Vorspannposition zwischen dem Anlenkpunkt und dem Hakenelement entgegen der Ziehrichtung vorgespannt ist.The object is achieved by a hook clamp, comprising a clamping hook with a hook element, the clamping hook being designed to pass through an opening of a component to be clamped, further comprising an actuator, the clamping hook being moved from an open position in a pulling direction by means of the actuator can be pulled to a closed position, the hook element in the closed position, in addition to the offset in the pulling direction, is offset in the direction of the hook end of the hook element, ie in a hook direction, the clamping hook comprising a first leg, the hook element being formed at a free end of the first leg, the clamping hook comprises a second leg arranged at an angle to the first leg, the actuator for pulling the clamping hook being articulated into the closed position on the second leg at a pivot point, the clamping hook being in a guide position between the pivot point and the hook element in an elongated hole in a Direction parallel to the pulling direction is mounted displaceably, wherein the clamping hook is biased by means of a spring element at a biasing position between the articulation point and the hook element against the pulling direction.

Erfindungsgemäß weist ein Hakenspanner somit einen Spannhaken auf, der aus zwei Schenkeln besteht, die in einem Winkel zueinander angeordnet sind, bevorzugt etwa in einem rechten Winkel zueinander.According to the invention, a hook tensioner thus has a tensioning hook which consists of two legs which are arranged at an angle to one another, preferably approximately at a right angle to one another.

Ein erster Schenkel dieses Spannhakens weist das Hakenelement, also den zum Ziehen notwendigen Haken auf. Der zweite Schenkel wird, insbesondere etwa an dessen freiem Ende, an einem Anlenkpunkt mit Hilfe eines Aktuators gezogen. Ein Ziehen des Anlenkpunkts, also eine Bewegung "nach hinten", bewirkt ein Ziehen des Hakenelements und somit ein Spannen eines zu spannenden Bauteils.A first leg of this clamping hook has the hook element, that is to say the hook necessary for pulling. The second leg is pulled, in particular at its free end, at a pivot point with the aid of an actuator. Pulling the articulation point, that is, a movement "backwards", causes the hook element to be pulled and thus a component to be clamped to be clamped.

Zwischen diesen beiden Enden des Spannhakens ist der Spannhaken noch in einem Langloch gelagert, so dass dieser einen durch das Langloch begrenzten Weg für eine Bewegung in einer Längsrichtung, nämlich der Ziehrichtung, hat. Diese Längsrichtung, also die Richtung des Langlochs, wird bevorzugt etwa der Richtung des ersten Schenkels des Spannhakens entsprechen.Between these two ends of the clamping hook, the clamping hook is also mounted in an elongated hole, so that it has a path limited by the elongated hole for a movement in a longitudinal direction, namely the pulling direction. This longitudinal direction, i.e. the direction of the elongated hole, will preferably correspond approximately to the direction of the first leg of the clamping hook.

Zusätzlich greift ein Federelement, ebenfalls zwischen Anlenkpunkt und Haken, bevorzugt am ersten Schenkel, insbesondere am Ende des ersten Schenkels des Spannhakens, an dem Spannhaken an, um diesen entgegen der Ziehrichtung, also "nach vorne", zu drücken. Das Federelement kann insbesondere eine Druckfeder sein.In addition, a spring element, also between the articulation point and the hook, preferably on the first leg, in particular on the end of the first leg of the clamping hook, engages the clamping hook in order to push it against the pulling direction, ie "forwards". The spring element can in particular be a compression spring.

Durch diese Ausbildung des Hackendspanners wird erreicht, dass bei einem Ziehen am Anlenkpunkt mittels Aktuator in einer geöffneten Stellung des Hackenspanners der Spannhacken "nach hinten" gezogen würde, dabei aber an der Vorspannposition zunächst mittels Federkraft des Federelements "nach vorne" gedrückt wird, so dass die Führungsposition zunächst an einem vorderen Ende des Langlochs verbleibt und das Hakenelement zunächst eine Bewegung "nach unten" vollzieht, also "in Hakenrichtung", und erst bei weiterem Ziehen mittels Aktuatorkraft in Ziehrichtung die Führungsposition innerhalb des Langlochs nach hinten verschoben wird und das Hakenelement somit nach hinten gezogen wird um gegebenenfalls ein vom Haken ergriffenes Bauteil zu spannen.This design of the hoe tensioner ensures that when the linkage point is pulled by means of an actuator in an open position of the hoe tensioner, the tensioning hook would be pulled "backwards", but at the pretensioning position it is initially pressed "forwards" by means of the spring force of the spring element, so that the guide position initially remains at a front end of the elongated hole and the hook element initially executes a movement "downward", i.e. "in the hook direction", and only with further pulling by means of actuator force in the pulling direction, the guide position within the elongated hole is shifted backwards and the hook element thus is pulled backwards in order to tension a component gripped by the hook if necessary.

Im Rahmen der Erfindung wird also als "hinten" die Richtung zum Hackenspanner hin, also die Zugrichtung bezeichnet. Etwa normal darauf steht die Richtung, in der der Haken zu seinem vorderen Ende hin, zum Eingreifen in ein Bauteil, bewegt wird, die als "nach unten" oder als "in Hackenrichtung" bezeichnet wird.In the context of the invention, the direction towards the heel tensioner, that is to say the direction of pull, is referred to as “rear”. Approximately normal to this is the direction in which the hook is moved towards its front end to engage a component, which is referred to as "downwards" or as "in the hook direction".

Umgekehrt kann zum Entspannen, also zum Öffnen des Hackenspanners, mittels Aktuator eine Kraft entgegen der Ziehrichtung aufgebracht werden, so dass sowohl die Aktuatorkraft als auch die Kraft des Federelements den Spannhacken "nach vorne" drücken. Wenn die Führungsposition dabei das vordere Ende des Langlochs erreicht, und somit dessen Bewegung begrenzt bzw. beendet ist, wird das Hakenelement bei weiterer Kraftbeaufschlagung mittels Aktuator am Anlenkpunkt wieder nach oben bewegt und der Spannhaken geöffnet.Conversely, in order to relax, that is to say to open the heel tensioner, a force against the pulling direction can be applied by means of the actuator, so that both the actuator force and the force of the spring element can Press the clamping hook "forwards". When the guide position reaches the front end of the elongated hole, and thus its movement is limited or terminated, the hook element is moved upwards again when further force is applied by means of the actuator at the articulation point and the clamping hook is opened.

Bei diesem Hackenspanner muss lediglich der Spannhacken bzw. das Hakenelement durch eine Öffnung des zu spannenden Bauteils geführt werden, so dass dafür eine kleine Öffnung ausreicht. Das Hakenelement kann bei diesem Aufbau einen größeren Weg zurücklegen und auch bei ungenauerer Positionierung oder Ausbildung des zu spannenden Bauteils dieses sicher ergreifen und mit hoher, nahezu konstanter Zugkraft ziehen.With this hook clamp only the clamping hook or the hook element has to be guided through an opening in the component to be clamped, so that a small opening is sufficient for this. With this construction, the hook element can cover a greater distance and, even if the component to be clamped is inaccurately positioned or formed, can safely grip it and pull it with a high, almost constant tensile force.

Die Kraft des Aktuator bewirkt dabei, im Zusammenspiel mit der Kraft des Federelements, eine Zugkraft in zwei Richtungen, nämlich einerseits in Ziehrichtung und zusätzlich in einer Richtung normal darauf, "nach unten", zum Schließen des Hakens.The force of the actuator, in interaction with the force of the spring element, causes a pulling force in two directions, namely on the one hand in the pulling direction and additionally in a direction normal to it, "downward", to close the hook.

Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen, der Beschreibung sowie den beigefügten Zeichnungen angegeben.Further developments of the invention are given in the dependent claims, the description and the accompanying drawings.

Vorzugsweise sind die Führungsposition und/oder die Vorspannposition im Übergangsbereich zwischen erstem Schenkel und zweitem Schenkel angeordnet, also in der Nähe desjenigen Endes des zweiten Schenkels, das in den ersten Schenkel übergeht oder in der Nähe desjenigen Endes des ersten Schenkels, das in den zweiten Schenkel übergeht.The guide position and / or the pretensioning position are preferably arranged in the transition area between the first leg and the second leg, i.e. in the vicinity of that end of the second leg which merges into the first leg or in the vicinity of that end of the first leg which in the second leg transforms.

Das Federelement ist bevorzugt eine einfache Druckfeder, die im Wesentlichen parallel zum ersten Schenkel ausgerichtet ist.The spring element is preferably a simple compression spring which is oriented essentially parallel to the first leg.

Der Aktuator umfasst vorzugsweise eine Betätigungsstange, die am Anlenkpunkt des Spannhakens angelengt ist und im Wesentlichen parallel zum ersten Schenkel ausgerichtet ist. Die Betätigungsstange kann auch durch ein mehrteiliges Bauteil gebildet werden und beispielsweise eine Spindel mit endseitigen Gabelköpfen zur Anlenkung umfassen.The actuator preferably comprises an actuating rod which is hinged to the articulation point of the clamping hook and is oriented essentially parallel to the first leg. The actuating rod can also be formed by a multi-part component and, for example, comprise a spindle with fork heads at the ends for articulation.

Bevorzugt ist die Betätigungsstange mittels eines Pneumatikzylinders und/oder mittels eines Elektromotors und/oder mittels eines Handhebels mit einer Kraft in Ziehrichtung beaufschlagbar.The actuating rod can preferably be acted upon by a force in the pulling direction by means of a pneumatic cylinder and / or by means of an electric motor and / or by means of a hand lever.

Die Kraft des Pneumatikzylinders, des Handhebels oder des Elektromotors in Ziehrichtung kann über einen Hebelmechanismus zur Kraftübersetzung auf die Betätigungsstange aufgebracht werden.The force of the pneumatic cylinder, the hand lever or the electric motor in the pulling direction can be applied to the actuating rod via a lever mechanism for force transmission.

Vorzugsweise ist am Spannhaken an der Führungsposition zwischen dem Anlenkpunkt und dem Hakenelement ein Führungsbolzen angeordnet, der in dem Langloch eines Führungsgehäuses in einer Richtung parallel zur Ziehrichtung verschiebbar gelagert ist.A guide bolt is preferably arranged on the clamping hook at the guide position between the articulation point and the hook element, which is mounted in the elongated hole of a guide housing so as to be displaceable in a direction parallel to the pulling direction.

Detaillierte Beschreibung der ErfindungDetailed description of the invention

In Fig. 1 ist ein erfindungsgemäßer Hackenspanner in einer ersten Ausführungsform in geöffneter Stellung dargestellt. Der selbe Hackenspanner ist in Fig. 2 in geschlossener Stellung und in Fig. 3 dreidimensional, eingeführt in ein zu spannendes Bauteil 14, dargestellt.In Fig. 1 an inventive hoe tensioner is shown in a first embodiment in the open position. The same hoe tensioner is in Fig. 2 in closed position and in Fig. 3 three-dimensional, introduced into a component 14 to be clamped.

Der Hackenspanner umfasst einen Spannhaken 1 mit einem Hakenelement 2. Dieser Spannhaken 1, insbesondere das Hakenelement 2, ist zur Durchführung durch eine Öffnung eines zu spannenden Bauteils 14 ausgebildet, wie in Fig. 3 dargestellt.The hook clamp comprises a clamping hook 1 with a hook element 2. This clamping hook 1, in particular the hook element 2, is designed to pass through an opening of a component 14 to be clamped, as in FIG Fig. 3 shown.

Der Hakenspanner umfasst ferner einen Aktuator 3, nämlich einen Pneumatikzylinder 9, so dass der Spannhaken 1 mittels des Aktuators 3 von einer geöffneten Stellung (Fig. 1) in einer Ziehrichtung x in eine geschlossene Stellung (Fig. 2) gezogen werden kann, wobei das Hakenelement 2 in der geschlossenen Stellung, zusätzlich zum Versatz in Ziehrichtung x, in einer Hakenrichtung y, zum Hakenende des Hakenelements 2 hin, versetzt ist.The hook tensioner also includes an actuator 3, namely a pneumatic cylinder 9, so that the tensioning hook 1 can be moved from an open position by means of the actuator 3 ( Fig. 1 ) in a pulling direction x to a closed position ( Fig. 2 ) can be pulled, the hook element 2 in the closed position, in addition to the offset in the pulling direction x, in a hook direction y, towards the hook end of the hook element 2, is offset.

Der Spannhaken 1 umfasst einen ersten Schenkel 4, wobei an einem freien Ende des ersten Schenkels 4 das Hakenelement 2 ausgebildet ist, und etwa im rechten Winkel zum ersten Schenkel 4 einen zweiten Schenkel 5, wobei an dem zweiten Schenkel 5 in einem Anlenkpunkt A der Aktuator 3 zum Ziehen des Spannhakens 1 in die geschlossene Stellung angelenkt ist. Der Anlenkpunkt A befindet sich etwa am freien Ende des zweiten Schenkels 5.The clamping hook 1 comprises a first leg 4, the hook element 2 being formed on a free end of the first leg 4, and approximately at right angles to the first leg 4, a second leg 5, the actuator 3 for pulling the clamping hook 1 into the closed position being linked to the second leg 5 at a pivot point A. The articulation point A is located approximately at the free end of the second leg 5.

Der Spannhaken 1 ist an einer Führungsposition F zwischen dem Anlenkpunkt A und dem Hakenelement 2 in einem Langloch 6 in einer Richtung parallel zur Ziehrichtung x verschiebbar gelagert.The clamping hook 1 is mounted at a guide position F between the articulation point A and the hook element 2 in an elongated hole 6 in a direction parallel to the pulling direction x.

Dazu weist der Spannhaken 1 einen Führungsbolzen 12 an der Führungsposition F auf. Das Langloch 6 ist in einem Führungsgehäuse 13 des Hackenspanners ausgebildet. Wie in Fig. 3 dargestellt, kann der Spannhaken 1 zusammen mit dem Führungsgehäuse 13 von einem Gehäusemantel 15 umschlossen sein. Der Aktuator 3 ist am Führungsgehäuse 13 befestigt.For this purpose, the clamping hook 1 has a guide pin 12 at the guide position F. The elongated hole 6 is formed in a guide housing 13 of the hook clamp. As in Fig. 3 shown, the clamping hook 1 can be enclosed together with the guide housing 13 by a housing jacket 15. The actuator 3 is attached to the guide housing 13.

Der Spannhaken 1 ist mittels eines Federelements 7 an einer Vorspannposition V zwischen dem Anlenkpunkt A und dem Hakenelement 2 entgegen der Ziehrichtung x vorgespannt. Das Federelement 7 ist eine Druckfeder, die im Wesentlichen parallel zum ersten Schenkel 4 ausgerichtet ist.The clamping hook 1 is prestressed by means of a spring element 7 at a prestressing position V between the articulation point A and the hook element 2 against the pulling direction x. The spring element 7 is a compression spring which is aligned essentially parallel to the first leg 4.

Der Aktuator 3 umfasst eine mehrteilige Betätigungsstange 8 zur Kraftübertragung an den Anlenkpunkt A des Spannhakens 1, die ebenfalls im Wesentlichen parallel zum ersten Schenkel 4 ausgerichtet ist.The actuator 3 comprises a multi-part actuating rod 8 for the transmission of force to the articulation point A of the clamping hook 1, which is also aligned essentially parallel to the first leg 4.

Ein in einem Führungsgehäuse mit einem Langloch eingebauter Spannhacken mit eingesetztem Führungsbolzen spannt und positioniert Bauteile aufgrund einer Zugbewegung.A clamping hook built into a guide housing with an elongated hole with inserted guide pin clamps and positions components due to a pulling movement.

Der Hakenspanner arbeitet derart, dass im geöffneten Zustand (Fig. 1) bei einer Zugbewegung mittels Pneumatikzylinder 9 (oder mittels Handhebel 10, Fig. 8) ein in einem Langloch 6 und Führungsgehäuse 13 geführter Spannhacken 1 zuerst mit einer Teilkraft nach unten, in Hakenrichtung y, gezogen wird. Diese erste Bewegung des Spannhackens 1 wird durch die Rückstellfeder 7 sichergestellt.The hook clamp works in such a way that when open ( Fig. 1 ) during a pulling movement by means of pneumatic cylinder 9 (or by means of hand lever 10, Fig. 8 ) a clamping hook 1 guided in an elongated hole 6 and guide housing 13 is first pulled down with a partial force, in hook direction y. This first movement of the clamping hook 1 is ensured by the return spring 7.

Der Spannhacken 1 trifft dann auf ein unten angebrachtes Anschlagstück, das Teil des Führungsgehäuses 13 sein kann, und bewegt sich aufgrund der Zugbewegung in weiterer Folge nach hinten, in Ziehrichtung x, zur Anlagefläche eines zu spannenden Bauteiles.The clamping hook 1 then strikes a stop piece attached below, which can be part of the guide housing 13, and due to the pulling movement subsequently moves backwards, in the pulling direction x, to the contact surface of a component to be clamped.

Die Spannkraft des Spannhackens 1 nach hinten zur Anlagefläche ist abhängig von der Kraft des Pneumatikzylinders 9, sowie der Gegenkraft der Rückstellfeder 7.The clamping force of the clamping hook 1 towards the rear towards the contact surface is dependent on the force of the pneumatic cylinder 9 and the counterforce of the return spring 7.

Die Teilkraft nach unten zum Anschlagstück ist abhängig von den beiden Schenkellängen des Spannhackens 1 sowie der Gegenkraft der Rückstellfeder 7.The partial force down to the stop piece is dependent on the two leg lengths of the clamping hook 1 and the counterforce of the return spring 7.

Beim Öffnen des Hackenspanners, aus der Position der Fig. 2, wird der Spannhacken 1 mittels Pneumatikzylinder 9 (oder mittels Handhebel 10, Fig. 8) unterstützt von der Rückstellfeder 7 nach vorne geschoben, entgegen der Ziehrichtung x.When opening the hook clamp, from the position of the Fig. 2 , the clamping hook 1 is actuated by means of a pneumatic cylinder 9 (or by means of a hand lever 10, Fig. 8 ) supported by the return spring 7 pushed forward, against the direction of pull x.

Der Führungsbolzen 12 des Spannhackens 1 erreicht dann das Ende des für den Bolzen 12 vorgesehenen Langlochs 6, und wird in weiterer Folge nach oben bis zu einem Anschlag des Spannhackens 1 gedrückt und erreicht so wieder den geöffneten Zustand gemäß Fig. 1.The guide bolt 12 of the clamping hook 1 then reaches the end of the elongated hole 6 provided for the bolt 12, and is then pushed upwards as far as a stop of the clamping hook 1 and thus again reaches the open state according to FIG Fig. 1 .

Fig. 4 ist eine Darstellung eines erfindungsgemäßen Hackenspanners in einer zweiten Ausführungsform in geöffneter Stellung. Dabei wird als Aktuator 3 wieder ein Pneumatikzylinder 9 verwendet, dieser Pneumatikzylinder 9 jedoch nicht, wie in den Figs. 1 bis 3 an der selben Seite des Führungsgehäuses 13 wie der Spannhaken 1 angeordnet, sondern an der dem Spannhaken 1 gegenüberliegenden Seite des Führungsgehäuses 13. Die Kraft des Pneumatikzylinders 9 wird mittels eines Hebelmechanismus 11 auf die Betätigungsstange 8 aufgebracht. Der Hebelmechanismus 11 umfasst dabei einen Hebel der durch eine Öffnung des Führungsgehäuses 13 hindurch geführt ist. Fig. 4 is a representation of a hoe tensioner according to the invention in a second embodiment in the open position. In this case, a pneumatic cylinder 9 is again used as actuator 3, but this pneumatic cylinder 9 is not, as in FIG Figs. 1 to 3 arranged on the same side of the guide housing 13 as the clamping hook 1, but on the side of the guide housing 13 opposite the clamping hook 1. The force of the pneumatic cylinder 9 is applied to the actuating rod 8 by means of a lever mechanism 11. The lever mechanism 11 comprises a lever which is guided through an opening in the guide housing 13.

Fig. 5 zeigt den selben Hackenspanners, in der zweiten Ausführungsform, jedoch in geschlossener Stellung des Spannhakens 1 bzw. Hakenelements 2. Fig. 5 shows the same hook clamp, in the second embodiment, but in the closed position of the clamping hook 1 or hook element 2.

Fig. 6 und Fig. 7 zeigen seitliche Schnittansichten des Hackenspanners in der zweiten Ausführungsform, in geöffneter Stellung (Fig. 4), sowie in geschlossener Stellung (Fig. 5). FIGS. 6 and 7 show side sectional views of the hook clamp in the second embodiment, in the open position ( Fig. 4 ), as well as in the closed position ( Fig. 5 ).

Eine dritte Ausführungsform eines erfindungsgemäßen Hackenspanners ist schließlich in den Figs. 8 bis 10 dargestellt, wobei Fig. 8 die geöffnete Stellung und Fig. 9 und Fig. 10 den Hakenspanner in geschlossener Stellung zeigen.A third embodiment of a heel tensioner according to the invention is finally in the Figs. 8 to 10 shown, where Fig. 8 the open position and Figures 9 and 10 show the hook tensioner in the closed position.

In dieser dritten Ausführungsform wird als Aktuator 3 ein Handhebel 10 benutzt, der wieder einen Hebelmechanismus 11 zur Kraftübertragung auf den Spannhaken 1 nutzt, wobei der Hebelmechanismus 11 durch das Führungsgehäuse 11 hindurch geführt ist. Die Aktuierung mittels Handhebel 10 zur Aufbringung einer Kraft in Ziehrichtung x kann beispielsweise durch Kraftunterstützungselemente, wie eine oder mehrere Federn 16, unterstützt sein.In this third embodiment, a hand lever 10 is used as actuator 3, which again uses a lever mechanism 11 for power transmission to the clamping hook 1, the lever mechanism 11 being guided through the guide housing 11. The actuation by means of a hand lever 10 for applying a force in the pulling direction x can be supported, for example, by force-supporting elements, such as one or more springs 16.
