Description

VORDERBACKEN FRONT JAW
Die Erfindung betrifft einen Vorderbacken gemäß dem Oberbegriff des Anspruches 1.The invention relates to a toe piece according to the preamble of claim 1.
Ein solcher Vorderbacken ist beispielsweise in der EP-A2 408 855 beschrieben. Bei dieser bekannten Lösung erfolgt sowohl die Entlastung der Winkelhebel bei nach oben wirkenden Kräften als auch die Auslösebewegung des Backens bei einem Rückwärtsdrehsturz durch Kippen des Lagerteils relativ zum Backengehäuse. Hingegen erfolgt die Anpassung des Sohlennie¬ derhalters an die jeweilige Schuhsohlendicke durch ein Ver¬ schieben des Lagerteils entlang der hinteren Querwand des Backengehäuses, wobei dafür zusätzlich Schrägflächen an Ge¬ häuse und Lagerteil ausgebildet sind.Such a front jaw is described for example in EP-A2 408 855. In this known solution, both the relief of the angle lever with upward forces and the release movement of the jaw takes place in the event of a reverse rotation by tilting the bearing part relative to the jaw housing. In contrast, the sole holder is adapted to the respective shoe sole thickness by sliding the bearing part along the rear transverse wall of the shoe housing, with additional inclined surfaces being formed on the housing and bearing part for this purpose.
Diese Lösung ist zwar durchaus praktikabel, es tritt aber beim Verschieben dieser Bauteile an den Kontaktflächen zwangsläufig Reibung auf.Although this solution is quite practical, there is inevitable friction when moving these components on the contact surfaces.
Aus der DE-OS 3734492 ist ein etwas anderer Vorderbacken bekannt, bei dem eine Verstellung und Entlastung der Sohlenhalter ebenfalls durch ein Verschieben und zwar entlang einer Schrägfläche des Gehäuses erfolgt. Dabei entsteht der schon oben genannte Nachteil.From DE-OS 3734492 a somewhat different toe piece is known, in which the sole holder is also adjusted and relieved by moving it along an inclined surface of the housing. This creates the disadvantage mentioned above.
Die Erfindung hat sich zum Ziel gesetzt, hier Abhilfe zu schaffen und bei einem Vorderbacken der eingangs genannten Art den Mechanismus für die automatische Anpassung des Vor¬ derbackens an die jeweilige Schuhsohlendicke so zu gestalten, daß möglichst wenig Reibung auftritt.The aim of the invention is to remedy this and to design the mechanism for the automatic adaptation of the toe to the respective shoe sole thickness in the case of a toe of the type mentioned at the outset so that as little friction as possible occurs.
Erfindungsgemäß wird diese Aufgabe durch die kennzeich¬ nenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.
Dadurch, daß bei im wesentlichen vertikal verlaufender hinterer Querwand des Gehäuses die vordere Stützwand des Lagerteils zwei in Höhenrichtung aneinandergrenzende Abschnitte aufweist, wobei der untere Abschnitt und der obere Abschnitt einen stumpfen Winkel miteinander einschließen, entsteht eine Kippkante, um welche der Lagerteil zur Anpassung an die Schuhsohle verschwenkbar ist. zCharacterized in that with a substantially vertical rear transverse wall of the housing, the front support wall of the bearing part has two sections adjoining one another in the vertical direction, the lower section and the upper section enclosing an obtuse angle with one another, a tilting edge is formed around which the bearing part adapts to the Shoe sole is pivotable. e.g.
Die Ausgestaltung nach den Merkmalen des Anspruches 2 erlaubt nach dem Ausschöpfen der durch die Kippkante mögli¬ chen Kippbewegung ein weiteres Verschwenken des Lagerteiles für die Bindungsauslösung.The embodiment according to the features of claim 2 allows, after exhausting the tilting movement possible by the tilting edge, a further pivoting of the bearing part for the release of the binding.
Weitere Vorteile, Merkmale und Einzelheiten des erfin¬ dungsgemäßen Vorderbackens werden nun anhand der Zeichnung näher beschrieben. Dabei zeigen Fig.l den Vorderbacken in der Draufsicht teilweise aufgerissen, Fig.2 einen Längsschnitt durch den Vorderbacken in der einstiegsbereiten Position der Skibindung, mit einem angedeuteten Skischuh,Fig.3 eine Darstellung wie Fig.2, mit einem eingesetzten Skischuh, mit dicker Sohle, Fig.4 die gleiche Ansicht mit etwas mehr verschwenktem Sohlenhalter, Fig.5 die Bindung mit maximal verschwenktem Sohlenhalter und die Figuren 6 und 7 eine Teilansicht von hinten, wobei die Bindung in Fig.6 in der Ruheposition und in Fig.7 seitlich nach oben verschwenkt dar¬ gestellt ist.Further advantages, features and details of the toe piece according to the invention will now be described in more detail with reference to the drawing. 1 shows the front jaw partially torn open, FIG. 2 shows a longitudinal section through the front jaw in the ready-to-start position of the ski binding, with an indicated ski boot, FIG. 3 shows a representation like FIG. 2, with a ski boot inserted, with a thicker one Sole, FIG. 4 the same view with the sole holder pivoted a little more, FIG. 5 the binding with the sole holder pivoted to the maximum, and FIGS. 6 and 7 a partial view from the rear, the binding in FIG. 6 in the rest position and in FIG. 7 laterally is shown pivoted upwards.
In den Figuren 1 und 2 ist der erfindungsgemäße Vorder¬ backen 1 in der einstiegsbereiten Stellung dargestellt. Er besitzt ein Gehäuse 2, das mittels nur angedeuteter Schrauben 51 auf einem Ski 50 befestigt ist. Im Gehäuse 2 ist eine Aus¬ lösefeder 40 untergebracht, deren Vorspannung in bekannter Weise durch eine Einsteilvorrichtung 43 eingestellt werden kann. Die Auslösefeder 40 ist zwischen einem Federteller 41 und, unter Zwischenschaltung einer Lagerbuchse 42, einer ver¬ tikal verlaufenden hinteren Querwand 3 des Gehäuses 2 ange¬ ordnet. Die Auslösefeder 40 wird in axialer Richtung von einer Zugstange 10 durchsetzt, deren eines Ende 11 mit der Einsteilvorrichtung 43 zusammenwirkt und deren anderes Ende 12 mit einer im wesentlichen vertikal verlaufenden Auslöse¬ platte 13 verbunden ist. Die Auslöseplatte 13 weist an ihrem unteren Ende 14 eine zur Skispitze hin gerichtete Steuerflä¬ che 15 und einen in Richtung Schuh 60 weisenden Anschlag 16 auf.1 and 2 show the toe 1 according to the invention in the position ready for entry. It has a housing 2, which is fastened to a ski 50 by means of only indicated screws 51. A release spring 40 is accommodated in the housing 2, the pretensioning of which can be adjusted in a known manner by an adjusting device 43. The release spring 40 is arranged between a spring plate 41 and, with the interposition of a bearing bush 42, a vertically running rear transverse wall 3 of the housing 2. The release spring 40 is penetrated in the axial direction by a pull rod 10, one end 11 of which cooperates with the adjusting device 43 and the other end 12 of which is connected to a substantially vertically extending release plate 13. The trigger plate 13 has at its lower end 14 a control surface 15 directed towards the ski tip and a stop 16 pointing in the direction of the shoe 60.
An die vertikal verlaufende hintere Querwand 3 des Gehäuses 2 schließt oben eine erste Kurve 5 und daran ein horizontal nach hinten verlaufender Abschnitt 6 an. An der Rückseite 4 der hinteren Querwand 3 des Gehäuses 2 liegt in der einstiegsbereiten Stellung des Vorderbackens 1 ein Lager¬ teil 20 mit seiner Stützwand 22 an. Der Lagerteil 20 ist von hinten gesehen rahmenförmig, d.h. für die Zugstange 10 mit einer Durchgangsöffnung 21 versehen, und hat - in Seitenan¬ sicht gesehen - etwa die Form eines C. Der vertikal verlau¬ fende Abschnitt des C ist durch die Stützwand 22 gebildet und ist mit einer vorderen Stützfläche 23 und einer hinteren Stützfläche 24 ausgestattet. In oberen und unteren Schenkeln 32,33 des C sind symmetrisch zur Längsmittelachse des Vorderbackens 2 zwei Achsen 34 für Winkelhebel 35 angeordnet. Die kürzeren Hebelarme 36 der beiden Winkelhebel 35 stützen sich einerseits an der Auslöseplatte 13 und andererseits an der hinteren Stützfläche 24 des Lagerteils 20 ab. Die längeren Hebelarme der Winkelhebel 35 sind als Sohlenhalter 37 zur Anlage an der Sohle 61 des in der Zeichnung nur angedeuteten Skischuhes 60 ausgebildet. Die vordere Stützfläche 23 des Lagerteiles 20 weist zwei in Höhenrichtung aneinander grenzende Abschnitte auf, wobei der -untere Abschnitt 25 in der einstiegsbereiten Stellung des Vorderbackens 2 betrachtet, an der Rückseite 4 der hinteren Querwand 3 des Gehäuses 2 anliegt. Der obere Abschnitt 26 schließt mit dem unteren Abschnitt 25 einen stumpfen Winkel α ein. Zwischen dem oberen Abschnitt 26 und dem unteren Abschnitt 25 hat der Lagerteil 20 eine Kippkante 27. Der obere Schenkel 32 des Lagerteiles 20 ist im Abschnitt der Längsmittelachse mit einer nach hinten und nach unten zu geneigten Fläche 28 ausgestattet. Der Übergang zwischen dem oberen Abschnitt 26 der vorderen Stützfläche 23 und der nach hinten und unten geneigten Fläche 28 ist als weitere Kurve 29 ausgebildet. In seinem unteren Abschnitt ist der Lagerteil 20 im Bereich der Längsmittelachse in der Draufsicht gabelförmig ausgebildet und weist eine nach vorne offene Ausnehmung 30 und einen nach hinten gerichteten Vorsprung 31 auf. Der Ausnehmung 30 ist ein entsprechender keilartiger Vorsprung 7 v. des Gehäuses 2 zugeordnet. Am Gehäuse 2 ist weiters ein dem Anschlag 16 der Auslöseplatte 13 zugewandter Wegbegrenzer 8 angeordnet.A first curve 5 closes at the top of the vertically running rear transverse wall 3 of the housing 2 and at it Section 6 running horizontally to the rear. On the rear side 4 of the rear transverse wall 3 of the housing 2 there is a bearing part 20 with its support wall 22 in the ready-for-entry position of the front jaw 1. The bearing part 20 is frame-shaped when viewed from the rear, that is to say provided with a through opening 21 for the pull rod 10, and — viewed from the side — has approximately the shape of a C. The vertically extending portion of the C is formed by the support wall 22 and is equipped with a front support surface 23 and a rear support surface 24. In the upper and lower legs 32, 33 of the C, two axes 34 for angle levers 35 are arranged symmetrically to the longitudinal central axis of the toe piece 2. The shorter lever arms 36 of the two angle levers 35 are supported on the one hand on the release plate 13 and on the other hand on the rear support surface 24 of the bearing part 20. The longer lever arms of the angle lever 35 are designed as sole holders 37 for contacting the sole 61 of the ski boot 60, which is only indicated in the drawing. The front support surface 23 of the bearing part 20 has two sections adjoining one another in the vertical direction, the lower section 25, viewed in the ready-to-enter position of the front jaw 2, abutting on the rear side 4 of the rear transverse wall 3 of the housing 2. The upper section 26 forms an obtuse angle α with the lower section 25. Between the upper section 26 and the lower section 25, the bearing part 20 has a tilting edge 27. The upper leg 32 of the bearing part 20 is provided in the section of the longitudinal central axis with a surface 28 which is inclined towards the rear and downwards. The transition between the upper section 26 of the front support surface 23 and the surface 28 which is inclined backwards and downwards is designed as a further curve 29. In its lower section, the bearing part 20 is fork-shaped in the plan view in the region of the longitudinal center axis and has a recess 30 open towards the front and a projection 31 directed towards the rear. The recess 30 is a corresponding wedge-like projection 7 v. assigned to the housing 2. A travel limiter 8 facing the stop 16 of the release plate 13 is also arranged on the housing 2.
Setzt man in die Skibindung einen Skischuh 60 ein, dessen Sohle 61 eine durchschnittliche Dicke (h-i) aufweist, so liegt der untere Abschnitt 25 der vorderen Stützfläche 23 des Lagerteiles 20 an der Rückseite 4 der hinteren Querwand 3 des Gehäuses 2 flächig an und der Lagerteil 20 berührt mit seiner Kurve 29 den horizontal nach hinten verlaufenden Abschnitt 6 des Gehäuses 2.If a ski boot 60 is inserted into the ski binding, the sole 61 of which has an average thickness (hi), the lower section 25 of the front support surface 23 of the bearing part 20 lies flat against the rear side 4 of the rear transverse wall 3 of the housing 2 and the bearing part 20 touches with its curve 29 the horizontally rearward section 6 of the housing 2.
Weist die Sohle 61 des Skischuhes 60 größere Dicke (h2) auf, so kippt, wie in Fig.3 erkennbar, der Lagerteil 20 leicht im Gegenuhrzeigersinn um die Kippkante 27. Dabei wird die Auslösefeder 40 geringfügig komprimiert. Somit stellt sich der Lagerteil 20 mit den Winkelhebeln 35 nach dem Entfernen des Skischuhes 60 selbsttätig in die Ausgangsläge zurück und es ist möglich, ohne jede zusätzliche Manipulation wahlweise Skischuhe mit dickerer oder dünnerer Sohle zu benützen.If the sole 61 of the ski boot 60 has a greater thickness (h 2 ), then, as can be seen in FIG. 3, the bearing part 20 tilts slightly counter-clockwise around the tipping edge 27. The release spring 40 is slightly compressed. Thus, the bearing part 20 with the angle levers 35 automatically returns to the starting position after removal of the ski shoe 60 and it is possible to use ski shoes with a thicker or thinner sole without any additional manipulation.
In den Figuren 4 und 5 ist dargestellt, wie Lagerteil 20 und Winkelhebel 35 bei einer nach oben gerichteten erhöhten Kraft, beispielsweise bei einem Rückwärtssturz oder Rück¬ wärtsdrehsturz, verschwenkt werden. Dabei wird der Lagerteil 20 gegen die Kraft der Auslösefeder 40 weiter um die Kipp¬ kante 27 verschwenkt. Wie in Fig.4 erkennbar, löst sich dabei die Auslöseplatte 13 von den kürzeren Hebelarmen 36 der Win¬ kelhebel 35. Dadurch wird ein zunächst kraftloses Verschwen¬ ken der Winkelhebel 35 für eine Seitwärtsauslösung ermög¬ licht. Außerdem gestattet die keilförmige Ausbildung des Vor¬ sprunges 7 im Zusammenwirken mit der Ausnehmung 30 ein seitliches Verschwenken des Lagerteiles 20 (s.Fig.6,7). Ein allzuweites Hochschwenken der Sohlenhalter 37 und damit ein unerwünschtes Freikommen des Skischuhes 60 wird dadurch ver¬ mieden, daß der Schwenkweg des Lagerteils 20 durch das Auf- treffen des Anschlages 16 der Auslöseplatte 13 auf den Wegbe¬ grenzer 8 begrenzt ist. FIGS. 4 and 5 show how the bearing part 20 and the angle lever 35 are pivoted in the event of an increased force directed upwards, for example in the event of a backward or backward turn. In this case, the bearing part 20 is pivoted further about the tilting edge 27 against the force of the release spring 40. As can be seen in FIG. 4, the release plate 13 detaches itself from the shorter lever arms 36 of the angle lever 35. This initially enables the angle lever 35 to be pivoted without force for sideways release. In addition, the wedge-shaped design of the projection 7 in cooperation with the recess 30 allows the bearing part 20 to pivot laterally (see FIGS. 6, 7). An excessive pivoting of the sole holder 37 and thus an undesired release of the ski boot 60 is avoided by the fact that the pivoting path of the bearing part 20 is limited by the impact of the stop 16 of the release plate 13 on the path limiter 8.
