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 26 28 748 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 heel hold-down device is described in DE-OS 26 28 748 (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 26 28 748) 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 (see Fig. 5 of DE-OS 26 28 748), 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 to be initiated, the ball of the ratchet mechanism 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 to involuntarily loosen the binding must be carried out is necessary, especially since the friction conditions are the same in both cases and the path by which the pre-tensioned detent spring is compressed in the event of an involuntary release corresponds approximately to the path by which the detent spring is compressed when the intermediate lever is moved from the entry position into the driving position becomes. 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 results in 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.l ist ein Längsschnitt durch eine erste Ausführungsform in der FahrtsteUung 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.l is a longitudinal section through a first embodiment in the FahrsteUung and Fig.2 in the boarding position. FIGS. 3-6 show a second embodiment 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.l 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 Achsstummeln 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 area 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 lla, 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 a control nose 11a on the side facing the unit 9, which in the event of an involuntary release of the heel hold-down device, e.g. in the event of a frontal fall, glides 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.

Im Falle einer unwillkürlichen Auslösung des Fersenniederhalters gleitet der Steuerhebel mit seiner Steuernase lla entlang der Innenseite der Einheit 9, die eine Steuerkurve trägt. In diesem Falle ist die Kraft der Rastfeder 3 voll wirksam. Ist jedoch die Endlage der Einheit 9, in der sich diese in der höchsten Stellung befindet, erreicht, so gelangt der Zapfen 20 des Steuerhebels 11 in die Rastnut 19 des Schenkels 13b. Will nun der Skiläufer mit seinem Skischuh in den Fersenniederhalter einsteigen, so wird die Einheit 9 entgegen dem Uhrzeigersinn nach unten geschwenkt, und die Steuernase 11a gleitet zu Beginn des Einsteigvorganges nicht mehr entlang der Innenseite der Einheit 9, sondern sie wird über einen Teil des Weges durch den Schenkel 13b im Abstand von der Steuerkurve in die Einheit nach oben geführt, bis die Steuernase Ila in einer Ausnehmung 21 der Einheit einrastet. Während dieses Wegabschnittes tritt lediglich eine Reibung in den Gelenken und eine Vorspannung der nicht dargestellten Feder des Winkelhebels 13, jedoch keine durch die Rastfeder 5 hervorgerufene Reibung zwischen der Innenseite der Einheit 9 und der Steuernase lla auf. Die zum Einsteigen erforderliche Kraft, ist infolgedessen wesentlich geringer als die Kraft, die zu einer unwillkürlichen Auslösung des Fersenniederhalters erforderlich ist.In the event of an involuntary release of the heel hold-down device, the control lever slides with its control nose 11a along the inside of the unit 9, which carries a control curve. In this case, the force of the detent spring 3 is fully effective. However, the end position of the unit 9 is in the reached in the highest position, the pin 20 of the control lever 11 enters the locking groove 19 of the leg 13b. If the skier now wants to step into the heel hold-down device with his ski boot, the unit 9 is pivoted downwards in a counterclockwise direction, and the control nose 11a no longer slides along the inside of the unit 9 at the beginning of the boarding process, but becomes part of the way through the leg 13b at a distance from the control curve into the unit upwards until the control lug Ila engages in a recess 21 of the unit. During this section of the path there is only friction in the joints and pretensioning of the spring of the angle lever 13, not shown, but no friction caused by the detent spring 5 between the inside of the unit 9 and the control lug 11a. As a result, the force required to get in is considerably less than the force required to trigger the heel hold-down involuntarily.

Soll jedoch eine willkürliche Auslösung des Fersenniederhalters herbeigeführt werden, so genügt es, das Federgehäuse 4 für die Rastfeder 3 in der einen oder anderen Richtung zu verschwenken. Dadurch gleitet aber das von der Rastfeder 5 beaufschlagte Druckglied 6 vom Vorsprung des Steuerhebels 11, wodurch dieser sich in Fig.l im Uhrzeigersinn verschwenken kann und dadurch die Einheit 9 zum Verschwenken freigibt.However, if an arbitrary triggering of the heel downholder is to be brought about, it is sufficient to pivot the spring housing 4 for the detent spring 3 in one direction or the other. As a result, however, the pressure member 6 acted upon by the detent spring 5 slides from the projection of the control lever 11, as a result of which it can pivot clockwise in FIG. 1 and thereby release the unit 9 for pivoting.

Bei dem in den Fig.3 - 6 dargestellten Ausführungsbeispiel ist der Zwischenhebel 131 im Gegensatz zum ersten Ausführungsbeispiel als einarmiger Hebel ausgebildet, der in einer Ausnehmung 12 der Einheit 9' um eine Achse 14 verschwenkbar ist. Am Zwischenhebel 13' und am Steuerhebel 11' sind ein Vorsprung 13a' und eine Rastnut 11c' angeordnet, welche in der Fahrtstellung des Fersenniederhalters voneinander getrennt, in der Einsteiglage hingegen miteinander im Eingriff sind. Der Zwischenhebel 13' trägt am freien Ende neben dem Vorsprung 13a' eine Rastnut 13b', wobei der Vorsprung 13a' in der Fahrtstellung des Fersenniederhalters in eine zweite Rastnut 11a' am Steuerhebel 11' eingreift und in dieser Stellung ein Vorsprung 11b' des Steuerhebels 11' in der Rastnut 13b' des Zwischenhebels 13' einrastet. Die beiden Rastnuten und Vorsprünge wirken nach Art eines Gelenkes zusammen. An die Rastnut 13b' schließt sich in Richtung zum Skischuh eine Steuerkurve 13c' an.In the exemplary embodiment shown in FIGS. 3-6, the intermediate lever 13 1, in contrast to the first exemplary embodiment, is designed as a one-armed lever which can be pivoted about an axis 14 in a recess 12 in the unit 9 '. On the intermediate lever 13 'and on the control lever 11', a projection 13a 'and a locking groove 11c' are arranged, which are separated from one another in the driving position of the heel hold-down device, but are in engagement with one another in the entry position. The intermediate lever 13 'carries a detent groove 13b' at the free end next to the protrusion 13a ', the protrusion 13a' engaging in a second detent groove 11a 'on the control lever 11' in the driving position of the heel hold-down device and in this position a protrusion 11b 'of the control lever 11 ' in the locking groove 13b 'of the intermediate lever 13' engages. The two locking grooves and projections work together in the manner of a joint. A control cam 13c 'adjoins the locking groove 13b' in the direction of the ski boot.

Die Funktion dieses Fersenniederhalters ist wie folgt: In der Fahrtstellung liegen die beiden Vorsprünge 13a' und llb' in den zugeordneten Rastnuten lla' und 13b'. Wird nun eine unwillkürliche Auslösung des Fersenniederhalters eingeleitet, so wird der Zwischenhebel 13' im Uhrzeigersinn verschwenkt. Dadurch drückt er den Steuerhebel 11' gegen die Wirkung der Rastfeder 5, die über das Druckglied 6 am Steuerhebel 11' angreift, zurück. Sobald eine gewisse Winkellage des Zwischenhebels 13' erreicht ist, hebt die Steuerkurve 13c' die beiden Vorsprünge 13a' und llb' aus den zugehörigen Rastnuten lla' und 13b', so daß die gelenkige Verbindung des Zwischenhebels 13' mit dem Steuerhebel 11' gelöst wird. Danach wird der Vorsprung 13a' von der Rastnut llc' aufgenommen. In dieser Lage ist der Fersenniederhalter bereit zum Einstieg des Skischuhs.The function of this heel hold-down device is as follows: In the travel position, the two projections 13a 'and 11b' lie in the associated locking grooves 11a 'and 13b'. If an involuntary release of the heel hold-down device is now initiated, the intermediate lever 13 'is pivoted clockwise. As a result, he presses the control lever 11 'back against the action of the detent spring 5, which acts on the control lever 11' via the pressure element 6. As soon as a certain angular position of the intermediate lever 13 'is reached, the control cam 13c' lifts the two projections 13a 'and 11b' out of the associated locking grooves 11a 'and 13b', so that the articulated connection of the intermediate lever 13 'with the control lever 11' is released . Then the projection 13a 'is received by the locking groove 11c'. In this position, the heel hold-down is ready to start the ski boot.

Steigt nun der Skiläufer mit seinem Skischuh in den Fersenniederhalter ein, so wird der Zwischenhebel 13' entgegen dem Uhrzeigersinn gegen den Boden der Ausnehmung 12 in der Einheit 9' verschwenkt. Dabei verläßt der Vorsprung 13a' des Zwischenhebels 13' die Rastnut llc' des Steuerhebels 11', und der Vorsprung llb' desselben legt sich an die Rückseite des Zwischenhebels 13' an. Sobald die Fahrtstellung des Fersenniederhalters erreicht ist, gelangen die beiden Vorsprünge 13a' und llb' in Eingriff mit den zugehörigen Ausnehmungen lla' und 13b'.If the skier now climbs into the heel holding-down device with his ski boot, the intermediate lever 13 'is pivoted counterclockwise against the bottom of the recess 12 in the unit 9'. The projection 13a 'of the intermediate lever 13' leaves the locking groove 11c 'of the control lever 11', and the projection 11b 'of the same engages the rear of the intermediate lever 13'. As soon as the travel position of the heel hold-down is reached, the two projections 13a 'and llb' come into engagement with the associated recesses 11a 'and 13b'.

Selbstverständlich ist die Erfindung nicht an die im vorstehenden beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiele gebunden. Vielmehr sind verschiedene Abänderungen derselben möglich, ohne den Rahmen der Erfindung zu verlassen. Beispielsweise kann die Schwenkachse für den Steuerhebel statt in der Nähe der Grundplatte auch im oberen Bereich des im wesentlichen U-förmigen Lagerbockes angeordnet sein. Weiters wäre es möglich, die erfindungsgemäßen Fersenniederhalter mit einer zusätzlichen Steuerkurve auszustatten, welche eine seitliche Auslösung des Fersenniederhalters, eine sogenannte "Diagonalauslösung" ermöglicht.Of course, the invention is not tied to the exemplary embodiments described above and shown in the drawing. Rather, various modifications thereof are possible without leaving the scope of the invention. For example, instead of in the vicinity of the base plate, the pivot axis for the control lever can also be in the upper region of the essentially U-shaped bearing block be arranged. Furthermore, it would be possible to equip the heel hold-down device according to the invention with an additional control curve, which enables a lateral release of the heel hold-down device, a so-called "diagonal release".
