Description

Die Erfindung bezieht sich auf einen Fersenhalter, wie er im Oberbegriff des Patentanspruches 1 angegeben ist.The invention relates to a heel holder, as specified in the preamble of claim 1.

Ein derartiger Fersenhalter ist nicht druckschriftlich vorveröffentlicht worden, sondern gehört einem firmeninternen Stande der Technik an. Bei jenem Fersenhalter ist die Schwenkachse für den Auslösehebel zusätzlich in einem Langloch geführt, welches etwa radial zur Schwenkachse des Steuerhebels in diesem verläuft. Dieser Fersenhalter hat den Nachteil, daß, da der am Auslösehebel vorgesehene Anschlag für das Bindungsgehäuse gleichzeitig die Begrenzung für das Hochschwenken des Niederhalters bildet, eine definierte Lage des Auslösehebels durch die Auslösefeder nicht immer gegeben ist. Daher kann es vorkommen, daß bei einer Einstellung der Vorspannung der Auslösefeder auf den unteren Wertbereich das Bindungsgehäuse bei einer Überlastung des Niederhalters, z. B. durch einen Schlag, über die vorgesehene Endlage geschwenkt wird. Der Auslösehebel kann nämlich in diesem Falle gegen die wirksame Kraftkomponente der schwach eingestellten Feder durch den Abstützbereich des Niederhalters am Fortsatz in Längsrichtung des Ski nach hinten geschoben werden, so daß der Niederhalter oberhalb des Fortsatzes zu liegen kommt. Die Auslösefeder drückt dann den Auslösehebel nach vorne, so daß beim Wiedereinsteigen dereFÖrtsatz dem Niederhalter im Wege steht.Such a heel holder has not been previously published in writing, but belongs to an in-house state of the art. In that heel holder, the pivot axis for the release lever is additionally guided in an elongated hole which runs approximately radially to the pivot axis of the control lever in the latter. This heel holder has the disadvantage that, since the stop provided on the release lever for the binding housing also forms the limit for the pivoting of the hold-down device, a defined position of the release lever by the release spring is not always given. Therefore, it can happen that when the preload of the release spring is set to the lower value range, the binding housing in the event of an overload of the hold-down device, e.g. B. is pivoted by a stroke over the intended end position. In this case, the release lever can be pushed against the effective force component of the weakly adjusted spring through the support area of the hold-down device on the extension in the longitudinal direction of the ski, so that the hold-down device comes to lie above the extension. The release spring then pushes the release lever forward, so that when you get back in, the release block gets in the way of the hold-down device.

Ein ähnlicher Fersenhalter ist in der US-A 3,773.341 beschrieben. Diese Ausführung hat einen Lagerbock, in dessen oberem Bereich eine Schwenkachse für ein Bindungsgehäuse mit Niederhalter und Trittsporn angeordnet ist. Im unteren Bereich des Lagerbockes ist eine weitere Schwenkachse für einen zweiteiligen Steuerhebel vorgesehen, der an einem Steuerelement des Bindungsgehäuses anliegt und unter dem Einfluß einer in ihrer Vorspannung einstellbaren Auslösefeder steht. Dabei erfolgt die Abstützung der Auslösefeder am Steuerhebel durch ein U-förmiges Federwiderlager, das mit seinen beiden Schenkeln an den beiden Teilen des Steuerhebels mittels Halbachsen angelenkt ist. Die beiden Halbachsen durchsetzen kreisbogenförmige Langlöcher in den Seitenwänden des Lagerbockes und tragen an den herausragenden Enden die Schenkel eines U-förmigen, einarmigen Auslösehebels, der sich an Ansätzen des Lagerbockes abstützt und zur willkürlichen Öffnung am Steuerhebel angreift.A similar heel holder is described in US-A 3,773,341. This version has a bearing block, in the upper area of which a pivot axis for a binding housing with hold-down device and step spur is arranged. In the lower area of the pedestal, a further pivot axis is provided for a two-part control lever which bears against a control element of the binding housing and is under the influence of a release spring which can be adjusted in its preload. The trigger spring is supported on the control lever by a U-shaped spring abutment, which is articulated with its two legs on the two parts of the control lever by means of semi-axles. The two semiaxes penetrate circular-shaped elongated holes in the side walls of the pedestal and carry the legs of a U-shaped, one-armed release lever at the protruding ends, which is supported on the approaches of the pedestal and acts on the control lever for arbitrary opening.

Diese Ausführung hat vor allem den Nachteil, daß zum Öffnen des Fersenhalters sich der Skiläufer bücken muß, da ein Öffnen nur durch Ziehen an einem Seil herbeigeführt werden kann. Darüber hinaus wird bei einer Auslösung die Auslösefeder, deren anderes Ende am Lagerbock verankert ist, nicht nur zusammengedrückt, sondern auch verbogen, was eine zusätzliche Arbeit darstellt. Ein ebenfalls ähnlicher Fersenhalter ist in der FR-A-1,485.708 beschrieben. Auch hier ist im oberen Bereich des Lagerbockes ein Bindungsgehäuse vertikal verschwenkbar angebracht, während im unteren Bereich ein unter Federdruck stehender Steuerhebel angelenkt ist, welcher im geschlossenen Zustand des Fersenhalters mit dem Bindungsgehäuse verrastet ist. Der Steuerhebel ist geschlitzt ausgeführt, in welchem Schlitz ein Auslösehebel, der für die willkürliche Öffnung des Fersenhalters am Bindungsgehäuse angreift, mittels eines Bolzens angelenkt ist. Bei seiner maximalen Verschwenkung schlägt ein Fortsatz des Auslösehebels am Lagerbock an. Eine Bewegung des Auslösehebels zum Skiende hin wird nur mittelbar, und zwar durch Anliegen des Steuerhebels am Federgehäuse, begrenzt. Bei dieser bekannten Lösung ist nachteilig, daß der Auslösehebel nur im Schlitz des Steuerhebels gelagert ist und dadurch eine instabile Führung hat. Außerdem ist der Steuerhebel durch den Schlitz geschwächt, welcher Umstand für den die Kräfte zu übertragenden Bauteil auch aus Sicherheitsgründen nachteilig ist.The main disadvantage of this design is that the skier has to bend down to open the heel holder, since opening can only be achieved by pulling on a rope. In addition, in the event of a release, the release spring, the other end of which is anchored to the bearing block, is not only compressed, but also bent, which represents additional work. A similar heel holder is described in FR-A-1,485,708. Here too, a binding housing is vertically pivoted in the upper area of the bearing block, while a control lever under spring pressure is articulated in the lower area, which is locked to the binding housing when the heel holder is closed. The control lever is slotted, in which slot a release lever, which acts on the binding housing for the arbitrary opening of the heel holder, is articulated by means of a bolt. At its maximum pivoting an extension of the release lever strikes the bearing block. A movement of the release lever towards the end of the ski is only indirectly limited, namely by the control lever resting on the spring housing. In this known solution, it is disadvantageous that the trigger lever is mounted only in the slot of the control lever and therefore has an unstable guidance. In addition, the control lever is weakened by the slot, which is disadvantageous for the component to be transmitted the forces also for safety reasons.

Des weiteren ist ein Fersenhalter in der DE-A-27 00 834 beschrieben, bei dem das Bindungsgehäuse mit einem von der Auslösefeder beaufschlagten, verschiebbaren Kolben verrastet ist. Folgedessen zeigt dieser Fersenhalter gegenüber dem Stand der Technik einen gattungsmäßigen Unterschied.Furthermore, a heel holder is described in DE-A-27 00 834, in which the binding housing is locked with a displaceable piston acted upon by the release spring. As a result, this heel holder shows a generic difference compared to the prior art.

Die Erfindung stellt sich die Aufgabe, diesen Nachteil zu beseitigen und einen Fersenhalter zu schaffen, bei dem die Lage des Auslösehebels auch dann in der Einsteigstellung des Fersenhalters zuverlässig festgelegt ist, wenn die Vorspannung der Auslösefeder beliebig geändert wird.The object of the invention is to eliminate this disadvantage and to provide a heel holder in which the position of the release lever is also reliably determined in the entry position of the heel holder if the bias of the release spring is changed as desired.

Ausgehend von einem Fersenhalter gemäß dem Oberbegriff des Patentanspruches 1 wird diese Aufgabe erfindungsgemäß durch die Maßnahmen des kennzeichnenden Teiles dieses Patentanspruches gelöst. Dadurch, daß die Lage des Auslösehebels in der Offenstellung des Bindungsgehäuses immer durch zwei Anschläge bestimmt wird, die mit die Verschiebebewegung und das Verschwenken des Auslösehebels bestimmenden Bindungsteilen zusammenwirken, wird gewährleistet, daß auch bei unterschiedlichen Vorspannungen der Auslösefeder der Auslösehebel in der Einsteiglage zuverlässig festgelegt ist.Starting from a heel holder according to the preamble of claim 1, this object is achieved according to the invention by the measures of the characterizing part of this claim. The fact that the position of the release lever in the open position of the binding housing is always determined by two stops which cooperate with binding parts which determine the displacement movement and the pivoting of the release lever, ensures that the release spring is reliably fixed in the entry position even with different preloads of the release spring .

Gemäß einer weiteren Ausgestaltung der Erfindung hat es sich als vorteilhaft erwiesen, wenn der erste Anschlag am Kraftarm des Auslösehebels als eine Querfläche ausgebildet ist, deren Normale durch den als Schwenkachse für den Auslösehebel dienenden Bolzen geht, und daß der zugehörige Gegenanschlag durch einen Ansatz am Bindungsgehäuse gebildet ist. Auf diese Weise wird die Lage des Auslösehebels in Skilängsrichtung in einfacher Weise konstruktiv bestimmt und damit das Verschwenkvermögen des Bindungsgehäuses nach oben definiert.According to a further embodiment of the invention, it has proven to be advantageous if the first stop on the power arm of the release lever is designed as a transverse surface, the normal of which passes through the bolt serving as a pivot axis for the release lever, and that the associated counter-stop is provided by an attachment on the binding housing is formed. In this way, the position of the release lever in the longitudinal direction of the ski is determined constructively in a simple manner and thus the pivoting capacity of the binding housing is defined upwards.

In dieser Richtung zielen auch die Merkmale des Anspruches 3, wobei sie eine Konstruktionsvariante zur vorhergehenden Lösung darstellen.The features of claim 3 also aim in this direction, representing a construction variant of the previous solution.

Durch die Merkmale des Anspruches 4 wird die Verschwenkung des Auslösehebels nach unten durch den Lagerbock selbst begrenzt.Due to the features of claim 4, the pivoting of the release lever downwards is limited by the bracket itself.

Eine andere Konstruktionsvariante für die Begrenzung der Verschwenkung des Auslösehebels nach unten ist durch die Merkmale des Anspruches 5 gegeben.Another design variant for limiting the pivoting of the release lever down is given by the features of claim 5.

Durch die Merkmale des Anspruches 6 ist eine Konstruktionsvariante gekennzeichnet, bei der ein gemeinsamer Gegenanschlag gleichzeitig zur Sicherung des Auslösehebels gegen eine Verschiebung nach hinten und eine Schwenkbewegung nach unten verwendet wird, was eine erhebliche Vereinfachung darstellt.A design variant is characterized by the features of claim 6, in which a common counter-stop is simultaneously used to secure the release lever against displacement to the rear and a pivoting movement downwards, which represents a considerable simplification.

In der Zeichnung sind beispielsweise Ausführungsformen des Erfindungsgegenstandes rein schematisch dargestellt. Fig. 1 ist ein Schnitt nach der Linie I-I in Fig. 2, Fig. 2 ein Schnitt nach der Linie 11-11 in Fig. 1 und Fig. 3 ein Schnitt nach der Linie 111-111 in Fig. 2, wobei alle Figuren den Fersenhalter in der Fahrtstellung darstellen. Die Fig. 4 und 5 zeigen den Fersenhalter in der Einsteiglage, u. zw. in Schnitten, welche den Fig. 1 und 3 entsprechen. In den Fig. 6-8 sind gegenüber dem ersten Ausführungsbeispiel abgeänderte Ausführungsformen dargestellt, wobei die Darstellungen der Fig. 5 entsprechen.In the drawing, for example, embodiments of the subject matter of the invention are shown purely schematically. Fig. 1 is a section along the line II in Fig. 2, Fig. 2 is a section along the line 11-11 in Fig. 1 and Fig. 3 is a section along the line 111-111 in Fig. 2, all the figures present the heel holder in the driving position. 4 and 5 show the heel holder in the boarding position, u. between in sections corresponding to FIGS. 1 and 3. FIGS. 6-8 show different embodiments compared to the first embodiment, the representations corresponding to FIG. 5.

In den Fig. 1-5 ist der Fersenhalter in seiner Gesamtheit mit 1 bezeichnet. Er besitzt eine Grundplatte 2, welche an ihrem dem Skischuh zugewandten Ende eine Aufbiegung 2a besitzt, die eine Steuerkurve für eine seitliche Auslösung trägt. Auf der Grundplatte 2 ist ein gehäuseförmiger Lagerbock 3 auf einer vertikalen Achse 4 schwenkbar gelagert. Dieser Lagerbock 3 greift mit einem an seiner Basis angeordneten Ansatz 3a in einen Schlitz 2b der Grundplatte 2 ein und wird von einer Abkröpfung 2c der Grundplatte 2 an einer Bewegung senkrecht zur Grundplatte gehindert. Auf diese Weise ist der Lagerbock 3 an seinem dem Skischuh benachbarten Ende gegen ein Abheben von der Grundplatte 2 gesichert.1-5 the heel holder is designated in its entirety by 1. It has a base plate 2 which, at its end facing the ski boot, has a bend 2a which carries a control cam for lateral triggering. On the base plate 2, a housing-shaped bearing block 3 is pivotally mounted on a vertical axis 4. This bearing block 3 engages with a projection 3a arranged on its base in a slot 2b of the base plate 2 and is prevented from being moved perpendicularly to the base plate by an offset 2c of the base plate 2. In this way, the bearing block 3 is secured at its end adjacent to the ski boot against lifting off from the base plate 2.

In der oberen Begrenzungswand des Lagerbockes 3 ist eine quer verlaufende Schwenkachse 5 angeordnet, auf der ein Bindungsgehäuse 6, das an seinem vorderen Ende einen Niederhalter 7 und einen Trittsporn 8 trägt, schwenkbar gelagert ist. In der vorderen Begrenzungswand des Bindungsgehäuses 6 ist eine nach unten hin offene, im Querschnitt rechteckige Nut 6a ausgespart, in der eine Rolle 9 auf einer Achse 10 gelagert ist, welche Rolle der Steuerkurve an der Aufbiegung 2a zugeordnet ist. Weiters trägt die vordere Begrenzungswand an ihrer dem Skischuh abgewendeten Seite eine Steuerkurve, die aus einem oberen Ast 6b und aus einem unteren Ast 6c besteht, welche Äste sich im Auslösepunkt des Fersenhalters 1 treffen.In the upper boundary wall of the bearing block 3, a transverse pivot axis 5 is arranged, on which a binding housing 6, which carries a hold-down device 7 and a step spur 8 at its front end, is pivotably mounted. In the front boundary wall of the binding housing 6, a downwardly open, cross-sectionally rectangular groove 6a is recessed, in which a roller 9 is mounted on an axis 10, which roller is assigned to the control curve on the bend 2a. Furthermore, on its side facing away from the ski boot, the front boundary wall carries a control cam, which consists of an upper branch 6b and a lower branch 6c, which branches meet at the trigger point of the heel holder 1.

Im unteren Bereich der Seitenwände des Lagerbockes 3 befindet sich auf der dem Skischuh zugewandten Seite eine zweite Achse 11, auf der ein Steuerhebel 12 schwenkbar gelagert ist. Der Steuerhebel 12 besitzt auf seiner dem Skischuh zugewandten Seite eine Nase 12a, welche zur Anlage an der Steuerkurve 6b, 6c bestimmt ist. An der der Nase 12a gegenüberliegenden Seite des Steuerhebels 12 ist eine in Querrichtung verlaufende, im Querschnitt kreissegmentförmige bzw. halbkreisförmige Nut ausgespart, in der ein Druckstück 13 schwenkbar gelagert ist. Dieses wird von einer Auslösefeder 14 beaufschlagt, deren anderes Ende sich an einem Federteller 15 abstützt, der einen Zeiger für die Größe der Vorspannung der Auslösefeder trägt und mittels einer Einstellschraube 16 in Richtung der Achse der Auslösefeder 14 verstellt werden kann. Die Einstellschraube 16 ist im Lagerbock 3 drehbar, aber gegen axiale Verschiebung gesichert gelagert. Der Federteller 15 ist im Lagerbock 3 geführt und sichert auf diese Weise den Federteller 15 gegen Verdrehen. Dabei bewegt sich der Zeiger in einem Schlitz 3b des Lagerbockes 3.In the lower region of the side walls of the bearing block 3 there is a second axis 11 on the side facing the ski boot, on which a control lever 12 is pivotably mounted. The control lever 12 has a nose 12a on its side facing the ski boot, which nose is intended to rest against the control curve 6b, 6c. On the side of the control lever 12 opposite the nose 12a, a groove running in the transverse direction, with a segment-shaped or semicircular cross-section, is recessed, in which a pressure piece 13 is pivotably mounted. This is acted upon by a release spring 14, the other end of which is supported on a spring plate 15 which bears a pointer for the magnitude of the preload of the release spring and can be adjusted in the direction of the axis of the release spring 14 by means of an adjusting screw 16. The adjusting screw 16 is rotatable in the bearing block 3, but is secured against axial displacement. The spring plate 15 is guided in the bearing block 3 and in this way secures the spring plate 15 against rotation. The pointer moves in a slot 3b of the bearing block 3.

Zwischen der Nase 12a und der im Querschnitt kreissegmentförmigen Nut trägt der Steuerhebel 12 einen in Querrichtung verlaufenden Bolzen 17, der kreisbogenförmige Langlöcher 3c in den Seitenwänden des Lagerbockes 3 durchsetzt und auf dessen über den Lagerbock hinausragenden Enden ein in Seitenansicht U-förmiger Auslösehebel 18 mit seinen Schenkeln schwenkbar gelagert ist. Das Ende 18a des Lastarmes jedes Schenkels des Auslösehebels 18 ist etwa hakenförmig ausgebildet und untergreift in der Fahrtstellung des Fersenhalters 1 einen Vorsprung 6d des Bindungsgehäuses 6 (s. Fig. 3). Außerdem trägt jeder Schenkel des Auslösehebels 18 noch einen anderen Vorsprung 18b, welcher in der Fahrtstellung sich an der einen Flanke 6c des Vorsprunges 6d des Bindungsgehäuses 6 anlegt. Dadurch ist die Lage des Auslösehebels 18 in der Fahrtstellung des Fersenhalters 1 eindeutig definiert.Between the lug 12a and the groove in the shape of a segment of a circle, the control lever 12 carries a bolt 17 running in the transverse direction, which penetrates arc-shaped elongated holes 3c in the side walls of the bearing block 3 and on its ends protruding beyond the bearing block is a side view of a U-shaped release lever 18 with its Legs is pivotally mounted. The end 18a of the load arm of each leg of the release lever 18 is approximately hook-shaped and engages under a projection 6d of the binding housing 6 in the travel position of the heel holder 1 (see FIG. 3). In addition, each leg of the release lever 18 carries another projection 18b which, in the driving position, bears against the one flank 6c of the projection 6d of the binding housing 6. As a result, the position of the release lever 18 in the driving position of the heel holder 1 is clearly defined.

Bei der Bewegung des Fersenhalters 1 in seine Einsteiglage im Zuge einer willkürlichen Auslösung hingegen wird zunächst das Bindungsgehäuse 6 mittels des Vorsprunges 18a des Auslösehebels 18 angehoben, wobei der obere Vorsprung 18b an der Flanke 6c des Vorsprunges 6d des Bindungsgehäuses 6 entlang gleitet, bis der Auslösehebel 18 an der Schwenkachse 5 für das Bindungsgehäuse 6 zur Anlage kommt. Gleichzeitig gelangt der erste Anschlag des Auslösehebels 18 der als eine Querfläche 18c ausgebildet ist in Berührung mit dem zugehörigen Gegenanschlag, der ein Ansatz 6f des Bindungsgehäuses 6 ist. Auf diese Weise ist der Auslösehebel 18 einerseits durch die Schwenkachse 5 und anderseits durch den Ansatz 6f des Bindungsgehäuses 6 in der Einsteiglage des Fersenhalters 1 zuverlässig auch dann festgehalten, wenn die Vorspannung der Auslösefeder 14 verändert wird.On the other hand, when the heel holder 1 moves into its entry position in the course of an arbitrary release, the binding housing 6 is first raised by means of the projection 18a of the release lever 18, the upper projection 18b sliding along the flank 6c of the projection 6d of the binding housing 6 until the release lever 18 comes to rest on the pivot axis 5 for the binding housing 6. At the same time, the first stop of the release lever 18, which is designed as a transverse surface 18c, comes into contact with the associated counterstop, which is an extension 6f of the binding housing 6. In this way, the release lever 18 is reliably held on the one hand by the pivot axis 5 and on the other hand by the extension 6f of the binding housing 6 in the entry position of the heel holder 1 even when the pretensioning of the release spring 14 is changed.

Auch bei der Ausführungsform 1' gemäß Fig. 6 trägt das Bindungsgehäuse 6 einen Ansatz 6f, welcher zur Anlage einer Querfläche 18c des Auslösehebels 18 bestimmt ist. Durch diesen Ansatz 6f ist der Auslösehebel 18 in der Einsteiglage des Fersenhalters 1' gegen Verschieben entgegen der Kraft der Auslösefeder gesichert. Um bei dieser Ausführungsform den Schwenkwinkel des Auslösehebels 18 zu begrenzen, trägt dieser an seinem den beiden Ansätzen 18a, 18b gegenüberliegenden Enden einen zweiten Anschlag 18 g, welcher zur Anlage an einer gehäuseartigen Abdeckung 3d des Lagerbockes 3 bestimmt ist. Die Schwenkachse 5 selbst befindet sich in der Einsteiglage des Fersenhalters 1' innerhalb einer nach unten hin offenen Aussparung 18f des Auslösehebels 18.In embodiment 1 'according to FIG. 6, the binding housing 6 also carries an extension 6f which is intended for the abutment of a transverse surface 18c of the release lever 18. By this approach 6f the release lever 18 is secured in the entry position of the heel holder 1 'against displacement against the force of the release spring. To at In this embodiment, to limit the pivoting angle of the release lever 18, it carries at its ends opposite the two shoulders 18a, 18b a second stop 18 g, which is intended for bearing against a housing-like cover 3d of the bearing block 3. The pivot axis 5 itself is in the entry position of the heel holder 1 'within a recess 18f of the release lever 18 which is open towards the bottom.

Eine weitere Ausführungsform eines Fersenhalters 1" gemäß der Erfindung ist in Fig. 7 wiedergegeben. Im Gegensatz zu den beiden vorhergehenden Ausführungsbeispielen fehlt bei dieser Ausführungsform der Ansatz am Bindungsgehäuse. Vielmehr wird hier der erste Anschlag des Auslösehebels von der Fläche 18d von der dem Bolzen 17 benachbarten Wand der Aussparung 18f gebildet. Ebenso wie beim vorhergehenden Ausführungsbeispiel dienen zur Festlegung des Auslösehebels 18 gegenüber einem Verdrehen der zweite Anschlag 18g, welcher sich in der Einsteiglage des Fersenhalters 1" an der gehäuseartigen Abdeckung 3d des Lagerbockes 3 abstützt.A further embodiment of a heel holder 1 "according to the invention is shown in FIG. 7. In contrast to the two previous exemplary embodiments, the approach to the binding housing is missing in this embodiment. Rather, the first stop of the release lever from surface 18d is from that of bolt 17 adjacent wall of the recess 18f. As in the previous exemplary embodiment, the second stop 18g, which is supported in the entry position of the heel holder 1 "on the housing-like cover 3d of the bearing block 3, serves to fix the release lever 18 against rotation.

Schließlich zeigt Fig. 8 eine letzte Variante eines erfindungsgemäßen Fersenhalters 1"', bei der sowohl die Sperre gegen ein Verschieben des Auslösehebels 18 als auch die gegen eine Verschwenkung desselben von der Schwenkachse 5 gebildet wird. Zu diesem Zwecke besitzt die Aussparung im Auslösehebel 18 außer einer Querfläche 18d, die den ersten Anschlag darstellt und . welche senkrecht zur Verbindungslinie der Schwenkachse 5 und des Bolzens 17 verläuft, eine weitere Fläche 18e', die den zweiten Anschlag bildet und welche parallel zur genannten Verbindungslinie angeordnet ist.Finally, FIG. 8 shows a last variant of a heel holder 1 "'according to the invention, in which both the lock against displacement of the release lever 18 and against the pivoting thereof is formed by the pivot axis 5. For this purpose, the recess in the release lever 18 also has a transverse surface 18d which represents the first stop and which runs perpendicular to the connecting line of the pivot axis 5 and the bolt 17, a further surface 18e 'which forms the second stop and which is arranged parallel to the mentioned connecting line.
