Abstract

A ski safety binding has a horizontally swivelling sole plate, a heel grip for the ski boot, and two double-armed sole grips which swivel about vertical sole grip bolts and fasten the edge of the sole of the ski boot with one of their lever arms. The other lever arm abuts, via a locking and control element, on a limit stop of the second front jaw element and is released when the sole plate deviates from a given swivelling angle. The locking and control element (8, 9) is pivotally mounted on an axis between the two sole grip bolts (11). The locking element (8) is approximately heart shaped and is provided with bearing surfaces for the two sole grips (7). The housing (4) can slide longitudinally in a manner known per se, and the control element (9) is designed as a rod which extends forward into a cavity (4b) in the housing (4) and which, in the deflected position of the sole plate (20), abuts on a stop (4c) of the housing (4).

Description

Die Erfindung betrifft eine Sicherheitsskibindung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a safety ski binding according to the preamble of claim 1.

Eine derartige Sicherheitsskibindung ist beispielsweise in der WO82/02495 beschrieben (s.Fig.14,15). Bei dieser bekamten Skibindung sind die Sohlenhalter als um je eine Hochachse verschwenkbare Winkelstücke ausgebildet, deren einer Schenkel die Skischuhsohle hält, während am anderen Schenkel jeweils ein Winkelhebel angelenkt ist. Die zueinander gerichteten Enden der Winkelhebel sind gelenkig miteinander verbunden uni von einer Schenkelfeder in Schließrichtung der Skibindung beaufschlagt. Die freien Enden der Winkelhebel sind nach vorne gerichtet. Bei einem Auslenken der Sohlenplatte berührt das freie Ende eines Winkelhebels einen skifesten Anschlag, was ein Verschwenken der Winkelhebel und der Sohlenhalter bewirkt.Such a safety ski binding is described, for example, in WO82 / 02495 (see Fig. 14, 15). In the case of this ski binding, the sole holders are designed as angle pieces which can be pivoted about a vertical axis, one leg of which holds the sole of the ski boot, while an angle lever is articulated on the other leg. The mutually directed ends of the angle levers are connected to one another in an articulated manner and acted upon by a leg spring in the closing direction of the ski binding. The free ends of the angle levers are facing forward. When the soleplate is deflected, the free end of an angle lever touches a ski-fixed stop, which causes the angle lever and the sole holder to pivot.

Diese bekannte Skibindung hat den Nachteil, daß der Vorderbacken aus vielen relativ zueinander beweglichen Einzelteilen besteht. Dadurch können einerseits an vielen Stellen schwer kontrollierbare Reibungskräfte auftreten, andererseits ist auch die Fertigung einer aus so vielen Einzelteilen bestehenden Skibindung aufwendig. Insbesondere ist bei dieser bekannten Skibindung für die Rückstellung der Verriegelungselemente und der Sohlenhalter nach einer Sicherheitsauslösung eine von der Auslösefeder, die im Fersenhalter angebracht ist und die Plattenbewegung steuert, getrennte Rückstellfeder erforderlich. Außerdem ist bei dieser bekannten Skibindung im Falle einer Skidurchbiegung aufgrund von Geländeunebenheiten nur ein geringfügiger Längsausgleich möglich, bevor ein Verklemmen eintritt.This known ski binding has the disadvantage that the toe consists of many individual parts that are movable relative to one another. On the one hand, this can cause friction forces that are difficult to control in many places, on the other hand, the production of a ski binding consisting of so many individual parts is also complex. In particular, in this known ski binding for the return of the locking elements and the sole holder after a safety release, a return spring separate from the release spring, which is attached in the heel holder and controls the plate movement, is required. In addition, with this known ski binding, in the event of a ski deflection due to uneven terrain, only a slight longitudinal compensation is possible before jamming occurs.

Eine etwas andere Lösung ist aus der AT-PS 372.867 bekannt. Bei dieser Skibindung stützen sich die Sohlenhalter in der Fahrtstellung an einem skifesten Widerlager ab. Dadurch entsteht bei einer Skidurchbiegung ein überhöhter Druck der Widerlager auf die Sohlenhalter, der von diesen auf die Skischuhsohle übertragen wird, was zu Verspannungen und damit zu verschlechterten Skifahreigenschaften und Auslösewerten führen kan.A somewhat different solution is known from AT-PS 372.867. With this ski binding, the sole holders are supported on a ski-fixed abutment in the riding position. In the event of a ski deflection, this creates an excessive pressure of the abutments on the sole holders, and of these on the ski boot sole is transmitted, which can lead to tension and thus to deteriorating skiing properties and release values.

Die vorliegende Erfindung hat es sich zum Ziel gesetzt, die genannten Nachteile zu vermeiden und eine Skibindung der eingangs genannten Art in ihrem Aufbau kompakter zu gestalten. uni die Anzahl der einzelnen Bauteile zu verringern. Weiters sollen Verspannungen der Skischuhsohle bzw. ein Verklemmen von Bindungsteilen bei Skidurchbiegung zuverlässig vermieden werden.The present invention has set itself the goal of avoiding the disadvantages mentioned and to make a ski binding of the type mentioned in its construction more compact. to reduce the number of individual components. Furthermore, tensioning of the ski boot sole or jamming of binding parts in the event of ski deflection should be reliably avoided.

Gelöst wird die gestellte Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1. Dadurch, daß das Verriegelungs- und das Steuerelement an einer mittig zwischen den Sohlenhalterbolzen auf der Sohlenplatte angeordneten Achse schwenkbar gelagert ist, wird ein kompakter Aufbau der Skibindung mit einer geringen Anzahl von Bauteilen erreicht. Durch die Anordnung des stabförmigen Steuerelementes in einer Freistellung des längsverschiebbaren Gehäuses wird ein Verspannen der Skischuhsohle oder ein Verklemmen der Bindungsgrundplatte zuverlässig vermieden. Ein in Skilängsrichtung verschiebbar angeordnetes Gehäuse ist aus der AT-PS 384.950 für sich bekannt.The object is achieved according to the invention by the characterizing features of claim 1. The fact that the locking and the control element is pivotally mounted on an axis arranged centrally between the sole holder bolts on the soleplate, makes a compact construction of the ski binding with a small number of components reached. The arrangement of the rod-shaped control element in an exemption of the longitudinally displaceable housing reliably prevents the sole of the ski boot from becoming jammed or the binding base plate from jamming. A housing which can be displaced in the longitudinal direction of the ski is known per se from AT-PS 384.950.

Die Ausgestaltung nach den Merkmalen des Anspruches 2 ermöglicht eine gemeinsame Bewegung des Verriegelungselementes mit dem Steuerelement.The embodiment according to the features of claim 2 enables a common movement of the locking element with the control element.

Durch die Maßnahme des Anspruches 3 wird die Verwendung von zusätzlichen Bauteilen eingespart.The measure of claim 3 saves the use of additional components.

Die Maßnahme des Anspruches 4 erleichtert dem Bindungsmonteur die Montage bzw. Längenanpassung der Skibindung ohne zeitraubende Manipulationen.The measure of claim 4 makes it easier for the binding fitter to assemble or adjust the length of the ski binding without time-consuming manipulations.

Die Merkmale des Anspruches 5 gewährleisten, daß die Skibindung nach einer Sicherheitsauslösung selbsttätig wieder in die einstiegsbereite Stellung gelangt.The features of claim 5 ensure that the ski binding automatically returns to the entry-ready position after a safety release.

Durch die Merkmale des Anspruches 6 wird eine zuverlässige Verbindung zwischen Gehäuse und Sohlenplatte auch beim Verschwenken der Sohlenplatte bei gleichzeitiger Vermeidung der Gefahr des Verklemmens gewährleistet. Diese Maßnahme ist aus der bereits genannten AT-PS 384.950 mit ihren Vorteilen für sich bekannt.The features of claim 6 provide a reliable connection between the housing and the soleplate even when the soleplate is pivoted while avoiding it the risk of jamming. This measure is known from the already mentioned AT-PS 384.950 with its advantages.

Vorteilhafterweise erstreckt sich, wie in Anspruch 7, der obere horizontale Bereich eines Trägerelememetes im wesentlichen über die Breite eines vorderen Endbereiches der Sohlenplatte.Advantageously, as in claim 7, the upper horizontal region of a support element extends essentially over the width of a front end region of the sole plate.

Die Ausgestaltung nach dem kennzeichnenden Teil des Anspruches 8 ermöglicht dem Konstrukteur, Ausschwenkpunkt und Ausschwenkbereich des Sohlenhalters wahlweise zu gestalten.The design according to the characterizing part of claim 8 allows the designer to design the pivoting point and pivoting range of the sole holder either.

Weitere Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die ein Ausführungsbeispiel zeigt, näher beschrieben.Further advantages and details of the invention will now be described with reference to the drawing, which shows an embodiment.

In der folgenden Beschreibung beziehen sich die Bezeichnungen vorne, hinten, links und rechts auf die Fahrtstellung der Skibindung, d.h. vorne bedeutet zur Skispitze hin gerichtet usw.In the following description, the designations front, rear, left and right refer to the position of the ski binding, i.e. front means towards the ski tip etc.

In Fig.1 ist eine nachfolgend näher zu beschreibende komplette Sicherheitsskibindung erkennbar. Die mit strichpunktierten Linien dargestellten Teile sind nicht Gegenstand der Erfindung und wurden nur der besseren Übersicht wegen dargestellt. Auf einem Ski 1 sind mittels teilweise nur angedeuteter Schrauben 2 eine Grundplatte 3 für einen Vorderbacken 10 und eine Montageplatte 5 für eine in bekannter Weise an einem Drehzapfen 6 schwenkbar gelagerte Sohlenplatte 20 befestigt. Die Sohlenplatte 20 trägt weiters einen Fersenhalter 30 sowie eine Skibremse 40, die bekannter Bauart sind, keinen Gegenstand der Erfindung bliden und daher auch nicht näher beschrieben werden.A complete safety ski binding to be described in more detail below can be seen in FIG. The parts shown with dash-dotted lines are not the subject of the invention and have only been shown for the sake of clarity. On a ski 1, a base plate 3 for a toe 10 and a mounting plate 5 for a sole plate 20 pivotably mounted on a pivot 6 in a known manner are fastened by means of screws 2, which are only partially indicated. The sole plate 20 also carries a heel holder 30 and a ski brake 40, the known type are not a subject of the invention and are therefore not described in detail.

In den Fig.2 und 3 ist der erfindungsgemäße Vorderbacken 10 in der Fahrtstellung der Skibindung dargestellt. Die Grundplatte 3 weist an beiden Seiten sich in Skilängsrichtung erstreckende, nach oben ragende Führungsschienen 3a auf. Auf der Grundplatte 3 ist ein Gehäuse 4 mittels seiner Basis 4a längsverschiebbar aber nicht abhebbar gelagert. Im hinteren Bereich des Gehäuses 4 ist eine Freistellung 4b für später noch zu beschreibende Teile des Vorderbackens 10 vorgesehen. Die Freistellung 4b weist an ihren seitlichen Rändern Anschläge 4c auf. An der Unterseite des Gehäuses 4 ist in dessen vorderem Bereich 4e eine in einer quer zur Skilängsrichtung und normal zur Skioberseite verlaufenden Ebene liegende Wegbegrenzung 4f vorhanden, welche gemeinsam mit dem Kopf der Schraube 2 die korrekte Positionierung des Gehäuses 4 relativ zur Grundplatte 3 bei der Längenanpassung der Skibindung ermöglicht. In einem oberen Bereich 4g des Gehäuses 4 ist an der der Freistellung 4b zugewandten Seite eine Führungsnut 4h ausgenommen. Die Führungsnut 4h verläuft entlang eines Kreisringstückes, dessen Mittellinie entlang eines Kreises gezogen ist, dessen Mittelpunkt in der Achse des Drehzapfens 6 liegt. Weiters sind im Gehäuse 4 Durchgangsbohrungen 4i für die Schrauben 2 vorgesehen. Eine quer verlaufende Innenwand 4j der Freistellung 4b ist seitlich mit je einer Steuerkurve 4d versehen.2 and 3 show the toe piece 10 according to the invention in the driving position of the ski binding. The base plate 3 has guide rails 3a which extend in the longitudinal direction of the ski and project upwards on both sides. On the base plate 3, a housing 4 is mounted by means of its base 4a so as to be longitudinally displaceable but not removable. In the rear area of the housing 4, an exemption 4b is provided for parts of the toe piece 10 to be described later. The exemption 4b has stops 4c on its lateral edges. On the underside of the housing 4 there is in its front area 4e a path 4f lying in a plane running transversely to the longitudinal direction of the ski and normal to the upper side of the ski, which together with the head of the screw 2 ensures the correct positioning of the housing 4 relative to the base plate 3 during the length adjustment of ski binding. In an upper region 4g of the housing 4, a guide groove 4h is cut out on the side facing the relief 4b. The guide groove 4h runs along a circular ring piece, the center line of which is drawn along a circle, the center point of which lies in the axis of the pivot pin 6. Furthermore, 4 through holes 4i are provided for the screws 2 in the housing. A transverse inner wall 4j of the exemption 4b is laterally provided with a control curve 4d.

Ein vorderer Endbereich 20a der Sohlenplatte 20 ist als Lagerstelle für Sohlenhalter 7 und einen noch näher zu beschreibenden Auslösemechanismus ausgebildet. Dazu weist die Sohlenplatte 20 an ihrem vorderen Endbereich 20a sich nach vorne erstreckende Laschen 20b auf. Im mittleren Breitenbereich des vorderen Endbereiches 20a der Sohlenplatte 20 erstreckt sich ein vertikaler beschnitt 20c. An den vertikalen Abschnitt 20c schließt ein nach vorne gerichteter horizontaler Abschnitt 20d an. Die Sohlenplatte 20 weist außerdem. an beiden Seiten hier nicht näher beschriebene Führungen 20e für einen nicht dargestellten hinteren Sohlenplattenteil auf. Ein Trägerelement 20f ist mit dem vorderen Endbereich 20a der Sohlenplatte 20 als Lagereinheit 20g ausgebildet. Ein unterer horizontaler Bereich 20h des Trägerelementes 20f erstreckt sich teilweise unter der Sohlenplatte 20, teilweise vor ieser. Daran schließt ein vertikaler Bereich 20i an, der zumindest teilweise parallel zum vertikalen Abschnitt 20v des vorderen Endbreiches 20a der Sohlenplatte 20 verläuft. Der vertikale Bereich 20i des Trägerelementes 20f weist an. beiden Seiten schräg verlaufende Anlageflächen 20n für die Sohlenhalter 7 auf. Ein an den vertikalen Bereich 20i des Trägerelementes 20f anschließender oberer horizontaler Bereich 20j erstreckt sich im wesentlichen über die Breite des vorderen Endbereiches 20a der Sohlenplatte 20. Im oberen horizontalen Bereich 20j ist ein Schlitz 20k vorgesehen, in welchem sich der horizontale Abschnitt 20d des vorderen Endbereiches 20a der Sohlenplatte 20 erstreckt. Der obere horizontale Bereich 20j besitzt weiters einen nach oben ragenden Vorsprung 20m, der mit Spiel in die Führungsnut 4h des Gehäuses 4 eingreift. An der dem Skischuh zugewandten Seite ist der obere horizontale Bereich 20j als Sohlenniederhalter 20o ausgebildet.A front end region 20a of the sole plate 20 is designed as a bearing point for the sole holder 7 and a trigger mechanism to be described in more detail. For this purpose, the sole plate 20 has straps 20b extending forward at its front end region 20a. A vertical trim 20c extends in the central width region of the front end region 20a of the sole plate 20. A vertical section 20d is connected to the vertical section 20c. The sole plate 20 also has. guides 20e not described here on both sides for a rear sole plate part, not shown. A support member 20f is formed with the front end portion 20a of the sole plate 20 as a bearing unit 20g. A lower horizontal region 20h of the carrier element 20f extends partly under the sole plate 20, partly in front of it. This is followed by a vertical region 20i, which runs at least partially parallel to the vertical section 20v of the front end region 20a of the sole plate 20. The vertical region 20i of the carrier element 20f instructs. on both sides inclined contact surfaces 20n for the sole holder 7. An upper horizontal region 20j adjoining the vertical region 20i of the carrier element 20f extends essentially over the width of the front end region 20a of the sole plate 20. In the upper horizontal region 20j, a slot 20k is provided, in which the horizontal section 20d of the front end region 20a of the sole plate 20 extends. The upper horizontal region 20j also has an upwardly projecting projection 20m which engages with play in the guide groove 4h of the housing 4. On the side facing the ski boot, the upper horizontal region 20j is designed as a sole hold-down device 20o.

In der Lagereinheit 20g sind eine vertikal verlaufende mittlere Achse 12 und zwei ebenfalls vertikal verlaufende Sohlenhalterbolzen 11 verankert. An den Sohlenhalterbolzen 11 sind die Sohlenhalter 7 angelenkt. Die Sohlenhalter 7 sind in ihrem hinteren Bereich in bekannter und daher nicht näher beschriebener Weise mit Anlageflächen für Skischuhschohlen ausgestattet. An ihrem vorderen Ende weisen die Sohlenhalter 7 nach unten gerichtete Zapfen 7a auf, deren Funktion später noch genauer beschrieben wird. An ihrer der Skilängsachse zugewandten Seite sind die Sohlenhalter 7 in ihrem vorderen Bereich in der Draufsicht kurvenförmig ausgebildet, wobei jede Kurve 7b in einem Riegelanschlag 7c endet. An dem dem Riegelanschlag 7c abgewandten Ende der Kurve 7b ist eine Anschnappkante 7d vorgesehen.A vertically running central axis 12 and two likewise vertically running sole holder bolts 11 are anchored in the bearing unit 20g. The sole holders 7 are articulated on the sole holder bolts 11. The sole holders 7 are equipped in their rear region in a known and therefore not described manner with contact surfaces for ski shoe coals. At their front end, the sole holders 7 have downward-facing pins 7a, the function of which will be described in more detail later. On their side facing the longitudinal axis of the ski, the sole holders 7 are curved in a plan view in their front region, each curve 7b ending in a locking stop 7c. At the end of the curve 7b facing away from the bolt stop 7c, a snap-on edge 7d is provided.

An der Achse 12 sind ein Verriegelungselement 8 und ein mit diesem gemeinsam verschwenkbares Steuerelement 9 angelenkt. Das Verriegelungselment 8 ist in der Draufsicht etwa herzförmig ausgebildet und weist Bogen 8a und zusammenlaufende gekrümmte Flächen 8b auf. Das Steuerelement 9 ist etwa stabförmig gestaltet und erstreckt sich, in der Fahrtstellung der Skibindung betrachtet, im Bereich der Skilängsachse von der Achse 12 nach vorne.A locking element 8 and a control element 9 which can be pivoted together with it are articulated on the axis 12. The locking element 8 is approximately heart-shaped in plan view and has arches 8a and converging curved surfaces 8b. The control element 9 is approximately rod-shaped and, viewed in the driving position of the ski binding, extends from the axis 12 to the front in the region of the longitudinal axis of the ski.

Tritt nun eine seitliche Belastung auf, so wird die Sohlenplatte 20 verschwenkt. Dabei nimmt sie das Verriegelungselement 8 und das Steuerelement 9 mit. Sobald das Steuerelement 9 den Anschlag 4c erreicht hat (s.Fig.4), beginnt es gemeinsam mit dem Verriegelungselement 8 um die Achse 12 zu schwenken. Bei einer den Elastizitätsbereich der Skibindung überschreitenden Kraft werden die Sohlenplatte 20 einerseits und die Einheit aus Verriegelungselement 8 und Steuerelement 9 andererseits weiterverschwenkt, bis der in der Schwenkrichtung gesehen voraneilende Sohlenhalter 7 mit seiner Abschnappkante 7d aus dem Bereich des Bogens 8a des Verriegelungselementes 8 freikommt (s. Fig.5) und den hier nicht dargestellten Skischuh ohne weiteren Kraftaufwand freigibt. Ein übermäßiges Verdrehen des Verriegelungselementes 8 und damit der Sohlenplatte 20 wird dabei dadurch verhindert, daß das Verriegelungselement 8 mit seiner der Verschwenkrichtung abgewandten gekrümmten Fläche 8b am Riegelanschlag 7c des zugehörigen Sohlenhalters 7 anliegt. Der Zapfen 7a begrenzt dabei dei Drehbewegung des Sohlenhalters 7 (s. Fig 6).If a lateral load now occurs, the sole plate 20 is pivoted. It takes the locking element 8 and the control element 9 with it. As soon as the control element 9 has reached the stop 4c (see FIG. 4), it begins to pivot together with the locking element 8 about the axis 12. If the force exceeds the elasticity range of the ski binding, the sole plate 20 on the one hand and the unit consisting of the locking element 8 and the control element 9 on the other hand are pivoted further until the sole holder 7 leading in the pivoting direction is released with its snap edge 7d from the area of the arch 8a of the locking element 8 (see Fig. 5) and releases the ski boot, not shown here, without further effort. Excessive rotation of the locking element 8 and thus of the sole plate 20 is prevented by the fact that the locking element 8 bears on the locking stop 7c of the associated sole holder 7 with its curved surface 8b facing away from the pivoting direction. The pin 7a limits the rotational movement of the sole holder 7 (see FIG. 6).

Wird nun die Sohlenplatte 20 nach einer Sicherheitsauslösung in die zentrierte Lage (Fahrtstellung) zurückbewegt, (s. Fig 7) so kommt der zugehörige Bogen 8a des Verriegelungselementes 8 mit der Steuerkurve 4d des Gehäuses 4 in Kontakt. Beim weiteren Zurückschwenken der Sohlenplatte 20 werden somit das Verriegelungselement 8 gemeinsam mit dem Steuerelement 9 und gleichzeitig, durch das Zusammenwirken zwischen der Abschnappkante 7d des Sohlenhalters 7 mit der zugehörigen gekrümmten Fläche 8b des Verriegelungselementes 8, auch der ausgeschwenkte Sohlenhalter 7 in die Ausgangsposition zurückgebracht.If the sole plate 20 is now moved back into the centered position (driving position) after a safety release (see FIG. 7), the associated bend 8a of the locking element 8 comes into contact with the control curve 4d of the housing 4. When the sole plate 20 is pivoted back further, the locking element 8 together with the control element 9 and at the same time, by the interaction between the snap edge 7d of the sole holder 7 and the associated curved surface 8b of the locking element 8, the swung out sole holder 7 is returned to the starting position.
