Description

Die Erfindung bezieht sich auf einen Fersenniederhalter gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a heel hold-down device according to the preamble of patent claim 1.

Ein derartiger Fersenniederhalter ist in der DE-OS-2 628 748 beschrieben (s. Fig. 3). Bei dieser Ausführung ist im Gegensatz zum Erfindungsgegenstand, bei dem die Steuerkurve an der aus Sohlenniederhalter und Trittsporn bestehenden Einheit angeordnet ist, die Steuerkurve am Zwischenhebel vorgesehen. Dieser Zwischenhebel trägt weiters an seinem oberen Ende einen Auslösehebel, der sich in der Fahrtstellung des Fersenniederhalters an einem durch die Einheit quer verlaufenden Bolzen abstützt. Im Falle einer willkürlichen Auslösung des Fersenniederhalters wird der Auslösehebel niedergedrückt, wodurch sich der Zwischenhebel gegen den Skischuh hin verschwenken kann und die am Zwischenhebel vorgesehene Steuerkurve außer Angriff mit dem Steuerglied kommt. Sobald jedoch die Endlage der Einheit erreicht ist, rastet der Auslösehebel wieder am quer verlaufenden Bolzen ein.Such a heel hold-down device is described in DE-OS-2 628 748 (see FIG. 3). In this embodiment, in contrast to the subject matter of the invention, in which the control cam is arranged on the unit consisting of sole hold-down device and step spur, the control cam is provided on the intermediate lever. This intermediate lever also carries at its upper end a release lever which is supported in the travel position of the heel hold-down device on a bolt which runs transversely through the unit. In the event of an arbitrary release of the heel hold-down device, the release lever is depressed, as a result of which the intermediate lever can pivot against the ski boot and the control curve provided on the intermediate lever comes out of engagement with the control member. However, as soon as the end position of the unit is reached, the release lever engages again on the transverse bolt.

Bei einer anderen Ausführungsform (vgl. Fig. 5 der DE-OS-2 628 748) sind die Einheit aus Sohlenniederhalter und Trittsporn, der Zwischenhebel und der Auslösehebel auf einer gemeinsamen Achse im Lagerbock gelagert. Der Zwischenhebel ist in der Fahrtstellung des Fersenniederhalters gegenüber der Einheit durch ein Kugelgesperre festgelegt. Soll nun eine willkürliche Auslösung des Fersenniederhalters eingeleitet werden, so wird die Kugel des Kugelgesperres durch den Auslösehebel zurückgedrückt und damit die Koppelung zwischen der Einheit und dem Zwischenhebel aufgehoben. Die Einheit kann danach ungehindert in die Offenstellung verschwenkt werden.In another embodiment (cf. FIG. 5 of DE-OS-2 628 748), the unit consisting of the sole hold-down device and step spur, the intermediate lever and the release lever are mounted on a common axis in the bearing block. The intermediate lever is fixed in the travel position of the heel hold-down device relative to the unit by a ball lock. If an arbitrary release of the heel hold-down device is now to be initiated, the ball of the ball lock is pushed back by the release lever and thus the coupling between the unit and the intermediate lever is released. The unit can then be pivoted freely into the open position.

Die beiden behandelten Ausführungsformen haben den Nachteil, daß beim Einsteigen des Skischuhs in den Fersenniederhalter etwa diejenige Arbeit aufgebracht werden muß, welche zum unwillkürlichen Lösen der Bindung erforderlich ist, zumal die Reibungsverhältnisse in beiden Fällen die gleichen sind und der Weg, um den die schon vorgespannte Rastfeder bei einer unwillkürlichen Auslösung zusammengedrückt wird, angenähert demjenigen Weg entspricht, um den die Rastfeder bei der Bewegung des Zwischenhebels aus der Einsteiglage in die Fahrtstellung zusammengedrückt wird. Das Einsteigen in die bekannten Fersenniederhalter ist daher kraftaufwendig. Außerdem müssen bei den bekannten Ausführungsformen die Zwischenhebel sehr massiv ausgebildet werden, da sie die volle Kraft der Rastfeder aufnehmen müssen, was eine unerwünschte Erhöhung des Gewichtes mit sich bringt.The two treated embodiments have the disadvantage that when the ski boot gets into the heel hold-down, approximately the work that is required for the involuntary loosening of the binding has to be applied, especially since the friction conditions are the same in both cases and the way around which the already preloaded The detent spring is compressed in the event of an involuntary release, approximately corresponds to the path by which the detent spring is compressed in the travel position when the intermediate lever is moved from the entry position. Climbing into the known heel hold-downs is therefore energy-intensive. In addition, in the known embodiments, the intermediate levers have to be made very solid, since they have to absorb the full force of the detent spring, which brings about an undesirable increase in weight.

Die Erfindung setzt sich zum Ziel, die angeführten Nachteile zu beseitigen und einen Fersenniederhalter zu schaffen, der es ermöglicht, die vom Skiläufer zu leistende, zum Einsteigen notwendige Arbeit erheblich herabzusetzen.The aim of the invention is to eliminate the disadvantages mentioned and to create a heel hold-down device which makes it possible to considerably reduce the work required by the skier for getting in.

Ausgehend von einem Fersenniederhalter gemäß dem Oberbegriff des Patentanspruches 1 wird dieses Ziel durch die Merkmale des kennzeichnenden Teiles dieses Anspruches erreicht.Starting from a heel hold-down device according to the preamble of claim 1, this aim is achieved by the features of the characterizing part of this claim.

In den Patentansprüchen 2 - 6 werden zweckmäßige und nützliche Weiterbildungen des Gegenstandes des Patentanspruches 1 unter Schutz gestellt.In the claims 2-6 expedient and useful developments of the subject matter of claim 1 are protected.

In der Zeichnung sind zwei beispielsweise Ausführungsformen von erfindungsgemäßen Fersenniederhaltern rein schematisch dargestellt. Fig. 1 ist ein Längsschnitt durch eine erste Ausführungsform in der Fahrtstellung und Fig. 2 in der Einsteiglage. In den Fig. 3 - 6 ist eine zweite Ausführungsform in der Fahrtstellung, während des unwillkürlichen Auslösevorganges, in der Einsteiglage und während des Einsteigvorganges wiedergegeben. Da dieser Fersenniederhalter in seinem Aufbau dem ersten weitgehend entspricht, sind hier nur die für die Steuerung wesentlichen Teile darsgestellt.In the drawing, two exemplary embodiments of heel hold-down devices according to the invention are shown purely schematically. Fig. 1 is a longitudinal section through a first embodiment in the driving position and Fig. 2 in the boarding position. 3 - 6, a second embodiment is shown in the driving position, during the involuntary triggering process, in the boarding position and during the boarding process. Since this heel hold-down largely corresponds to the first in its construction, only the parts essential for the control are shown here.

Der in den Fig. 1 und 2 dargestellte Fersenniederhalter besitzt eine Grundplatte 1, an der ein im Querschnitt im wesentlichen U-förmiger Lagerbock 2 befestigt ist. Im oberen Bereich der beiden Schenkeln des Lagerbockes 2 sind zwei Achsstummel 3 angeordnet, um welche einerseits ein Federgehäuse 4 für eine Rastfeder 5, welche ein Druckglied 6 beaufschlagt, und anderseits eine aus einem Sohlenniederhalter 7 und einem Trittsporn 8 bestehende Einheit 9 unabhängig voneinander verschwenkbar sind. Im unteren Bereich der Schenkel des Lagerbockes 2 befindet sich eine Achse 10, auf welcher ein Steuerhebel 11 verdrehbar angeordnet ist. Dieser befindet sich in dem Zwischenraum zwischen dem Druckglied 6 und der Einheit 9. An der Rückseite der Einheit 9 ist eine Ausnehmung 12 ausgespart, in der ein als Winkelhebel ausgebildeter Zwischenhebel 13 gelagert ist, dessen Schenkel mit 13a und 13b bezeichnet sind. Die Schwenkachse 14 des Zwischenhebels 13 befindet sich im unteren Bereich der Ausnehmung 12. Der Zwischenhebel 13 steht unter dem Einfluß einer nicht dargestellten Feder, welche bestrebt ist, den einen Schenkel 13a des Winkelhebels 13 gegen den Grund der Ausnehmung 12 zu drücken.The heel hold-down device shown in FIGS. 1 and 2 has a base plate 1 to which a bearing block 2 which is essentially U-shaped in cross section is fastened. In the upper region of the two legs of the bearing block 2, two stub axles 3 are arranged, around which, on the one hand, a spring housing 4 for a detent spring 5, which acts on a pressure member 6, and on the other hand, a unit 9 consisting of a sole hold-down 7 and a step spur 8 can be pivoted independently of one another . In the lower region of the legs of the bearing block 2 there is an axis 10 on which a control lever 11 is rotatably arranged. This is located in the space between the pressure member 6 and the unit 9. At the rear of the unit 9 there is a recess 12 in which an intermediate lever 13, which is designed as an angle lever, is mounted, the legs of which are designated 13a and 13b. The pivot axis 14 of the intermediate lever 13 is located in the lower region of the recess 12. The intermediate lever 13 is under the influence of a spring, not shown, which tends to press one leg 13a of the angle lever 13 against the bottom of the recess 12.

Der Steuerhebel 11 besitzt auf der der Einheit 9 zugewendeten Seite eine Steuernase 11 a, welche im Falle einer unwillkürlichen Auslösung des Fersenniederhalters, z. B. bei einem Frontalsturz, entlang der Innenseite der Einheit 9 gleitet. Weiters trägt der Steuerhebel 11 an seinem oberen Ende einen Zapfen 20, der zum Eingriff in eine Rastnut 19 bestimmt ist, welche am Ende des anderen Schenkels 13b des Winkelhebels 13 ausgespart ist. Diese Rastnut 19 ist in der Zeichnung rechtwinkelig dargestellt, sie kann jedoch auch im Querschnitt V-förmig ausgebildet sein.The control lever 11 has on the side facing the unit 9 a control nose 11 a, which in the event of an involuntary triggering of the heel hold-down device, e.g. B. in a frontal fall, slides along the inside of the unit 9. Furthermore, the control lever 11 carries at its upper end a pin 20 which is intended to engage in a locking groove 19 which is recessed at the end of the other leg 13b of the angle lever 13. This locking groove 19 is shown at right angles in the drawing, but it can also have a V-shaped cross section.
