Definitions
- the invention relates to a toe piece according to the preamble of claim 1.
- Such a front jaw is described for example in EP-A2 408 855.
- the known front jaw has a rear transverse wall, the surface on which the bearing part is supported runs in different planes.
- the transverse wall in the upper and lower end region has inclined sections which take place at differently large angles, so that a tight fit of the bearing part against the transverse wall is not possible in a relatively large area.
- the known front jaw has a back and down curved surface of the bearing part, which, however, cannot fulfill a limiting function for the pivoting movement of the bearing part.
- 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.
- the sole hold-down is adapted to the respective shoe sole thickness by moving the bearing part along the rear transverse wall of the shoe housing, with inclined surfaces being additionally formed on the housing and bearing part for this purpose.
- the bearing part has in its lower section a rearward projection which is supported on the vertical bar (release plate). This ensures safe power transmission for the overall function of the toe piece during a triggering process.
- the front support wall of the bearing part has two sections adjoining one another in the height direction, the lower section and the upper section enclosing an obtuse angle with one another. This creates a tipping edge around which the bearing part can be pivoted to adapt to the sole of the shoe.
- the invention has set itself the goal of remedying this situation and, in the case of a toe of the type mentioned at the outset, to design the mechanism for the automatic adaptation of the toe to the respective shoe sole thickness in such a way that as little friction as possible occurs.
- the embodiment according to the features of claim 2 allows a further pivoting of the bearing part for the release of the binding after exhausting the tilting movement possible by the tilting edge.
- FIG. 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 an inserted ski boot, 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
- FIGS. 6 and 7 a partial view from the rear, the binding in FIG. 6 in the rest position and in FIG. 7 to the side is shown pivoted upwards.
- the front jaw 1 is shown 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 housed, the bias 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.
- 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.
- 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 has — viewed in side view — approximately the shape of a C.
- the vertically extending section of the C is formed by the support wall 22 and has a front Support surface 23 and a rear support surface 24 equipped.
- 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 ⁇ 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.
- the bearing part 20 is fork-shaped in the area of the longitudinal central axis in plan view and has a recess 30 which is open towards the front and a projection 31 which is directed towards the rear.
- the recess 30 is a corresponding wedge-like projection 7 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.
- the bearing part 20 tilts, as can be seen in FIG. 3, slightly counterclockwise around the tipping edge 27.
- the trigger spring 40 is compressed slightly.
- the bearing part 20 with the angle levers 35 automatically returns to the starting position after the ski shoe 60 has been removed, and it is possible to use ski shoes with a thicker or thinner sole without any additional manipulation.
- FIGS. 4 and 5 show how the bearing part 20 and the angle lever 35 are pivoted in the event of an upward increased force, for example in the event of a backward fall or backward turn fall.
- the bearing part 20 is pivoted further about the tilting edge 27 against the force of the release spring 40.
- 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 a sideways release.
- 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 up of the sole holder 37 and thus an undesired release of the ski boot 60 is avoided in 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 travel limiter 8.

Abstract
Description
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. Der bekannte Vorderbacken weist eine hintere Querwand auf, deren Fläche, an der sich der Lagerteil abstützt, in verschiedenen Ebenen verläuft. Somit weist die Querwand im oberen und unteren Endbereïch schräge Abschnitte auf, die unter verschieden großen Winkeln erfolgen, so daß ein sattes Anliegen des Lagerteils an der Querwand in einem verhältnismäßig großen Bereich nicht möglich ist. Desweiteren weist der bekannte Vorderbacken eine nach hinten und unten gekrümmte Fläche des Lagerteils auf, welche jedoch keine begrenzende Funktion für die Schwenkbewegung des Lagerteils erfüllen kann.Such a front jaw is described for example in EP-A2 408 855. The known front jaw has a rear transverse wall, the surface on which the bearing part is supported runs in different planes. Thus, the transverse wall in the upper and lower end region has inclined sections which take place at differently large angles, so that a tight fit of the bearing part against the transverse wall is not possible in a relatively large area. Furthermore, the known front jaw has a back and down curved surface of the bearing part, which, however, cannot fulfill a limiting function for the pivoting movement of the bearing part.
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 Sohlenniederhalters an die jeweilige Schuhsohlendicke durch ein Verschieben des Lagerteils entlang der hinteren Querwand des Backengehäuses, wobei dafür am Gehäuse und Lagerteil zusätzlich Schrägflächen ausgebildet sind. Weiters weist der Lagerteil in seinem unteren Abschnitt einen nach hinten gerichteten Vorsprung auf, der sich am vertikalen Balken (Auslöseplatte) abstützt. Dadurch wird eine sichere Kraftübertragung für die Gesamtfunktion des Vorderbackens bei einem Auslösevorgang gewährleistet. Die vordere Stützwand des Lagerteils weist zwei in Höhenrichtung aneinandergrenzende Abschnitte auf, wobei der untere Abschnitt und der obere Abschnitt miteinander einen stumpfen Winkel einschließen. Dadurch entsteht eine Kippkante, um welche der Lagerteil zur Anpassung an die Schuhsohle verschwenkbar ist.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. On the other hand, the sole hold-down is adapted to the respective shoe sole thickness by moving the bearing part along the rear transverse wall of the shoe housing, with inclined surfaces being additionally formed on the housing and bearing part for this purpose. Furthermore, the bearing part has in its lower section a rearward projection which is supported on the vertical bar (release plate). This ensures safe power transmission for the overall function of the toe piece during a triggering process. The front support wall of the bearing part has two sections adjoining one another in the height direction, the lower section and the upper section enclosing an obtuse angle with one another. This creates a tipping edge around which the bearing part can be pivoted to adapt to the sole of the shoe.
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 anders gestalteter Vorderbacken bekannt, bei dem eine Verstellung und Entlastung der Sohlenhalter ebenfalls durch ein Verschieben, u.zw. entlang einer Schrägfläche des Gehäuses erfolgt. Dabei entsteht der schon oben genannte Nachteil.From DE-OS 3734492 a somewhat differently designed toe piece is known, in which an adjustment and relief of the sole holder is also achieved by moving, etc. takes place 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 Vorderbackens an die jeweilige Schuhsohlendicke so zu gestalten, daß möglichst wenig Reibung auftritt.The invention has set itself the goal of remedying this situation and, in the case of a toe of the type mentioned at the outset, to design the mechanism for the automatic adaptation of the toe to the respective shoe sole thickness in such a way that as little friction as possible occurs.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.
Dadurch, daß die hintere Querwand des Gehäuses, an der sich der Lagerteil abstützt, in einer in wesentlichen vertikalen Ebene verläuft, wird gewährleistet, daß der Lagerteil in allen seinen definierten Lagen großflächig satt an der Querwand anliegt. Durch die Maßnahme, daß an dem oberen Abschnitt der vorderen Stützfläche des Lagerteils eine nach hinten und nach unten zu geneigte Fläche anschließt, wird gewährleistet, daß diese Stützfläche zur Schwenkbegrenzung des Lagerteils dient. Die Auslöseplatte an ihren unteren Endabschnitt mit einer zur Skispitze hin gerichteten, nach innen gewölbten Steuerfläche zu versehen, bewirkt, daß die beim Hochschwenken der Sohlenhalter zunehmende Kraft der Auslösefeder in jeder Schwenklage des Lagerteiles vollständig auf die Steuerfläche des Lagerteils übertragen wird.Characterized in that the rear transverse wall of the housing, on which the bearing part is supported, runs in a substantially vertical plane, it is ensured that the bearing part abuts the transverse wall over a large area in all of its defined positions. The measure that a rearward and downward inclined surface adjoins the upper portion of the front support surface of the bearing part ensures that this support surface serves to limit the pivoting of the bearing part. Providing the release plate at its lower end section with an inwardly curved control surface directed towards the ski tip has the effect that the force of the release spring, which increases when the sole holder is pivoted up, is completely transmitted to the control surface of the bearing part in every pivoting position of the bearing part.
Die Ausgestaltung nach den Merkmalen des Anspruches 2 erlaubt nach dem Ausschöpfen der durch die Kippkante möglichen Kippbewegung ein weiteres Verschwenken des Lagerteiles für die Bindungsauslösung.The embodiment according to the features of
Weitere Vorteile, Merkmale und Einzelheiten des erfindungsgemäßen Vorderbackens werden nun anhand der Zeichnung näher beschrieben. Dabei Zeigen Fig.1 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 dargestellt 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 an inserted ski boot, 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 to the side is shown pivoted upwards.
In den Figuren 1 und 2 ist der erfindungsgemäße Vorderbacken 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 Auslösefeder 40 untergebracht, deren Vorspannung in bekannter Weise durch eine Einstellvorrichtung 43 eingestellt werden kann. Die Auslösefeder 40 ist zwischen einem Federteller 41 und, unter Zwischenschaltung einer Lagerbuchse 42, einer vertikal verlaufenden hinteren Querwand 3 des Gehäuses 2 angeordnet. Die Auslösefeder 40 wird in axialer Richtung von einer Zugstange 10 durchsetzt, deren eines Ende 11 mit der Einstellvorrichtung 43 zusammenwirkt und deren anderes Ende 12 mit einer im wesentlichen vertikal verlaufenden Auslöseplatte 13 verbunden ist. Die Auslöseplatte 13 weist an ihrem unteren Ende 14 eine zur Skispitze hin gerichtete Steuerfläche 15 und einen in Richtung Schuh 60 weisenden Anschlag 16 auf.In Figures 1 and 2, the front jaw 1 according to the invention is shown in the position ready for entry. It has a
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 Lagerteil 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 Seitenansicht gesehen - etwa die Form eines C. Der vertikal verlaufende 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 des Gehäuses 2 zugeordnet. Am Gehäuse 2 ist weiters ein dem Anschlag 16 der Auslöseplatte 13 zugewandter Wegbegrenzer 8 angeordnet.A
Setzt man in die Skibindung einen Skischuh 60 ein, dessen Sohle 61 eine durchschnittliche Dicke (h₁) 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 you insert a
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 Ausgangslage zurück und es ist möglich, ohne jede zusätzliche Manipulation wahlweise Skischuhe mit dickerer oder dünnerer Sohle zu benützen.If the sole 61 of the
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 Rückwärtsdrehsturz, verschwenkt werden. Dabei wird der Lagerteil 20 gegen die Kraft der Auslösefeder 40 weiter um die Kippkante 27 verschwenkt. Wie in Fig.4 erkennbar, löst sich dabei die Auslöseplatte 13 von den kürzeren Hebelarmen 36 der Winkelhebel 35. Dadurch wird ein zunächst kraftloses Verschwenken der Winkelhebel 35 für eine Seitwärtsauslösung ermöglicht. Außerdem gestattet die keilförmige Ausbildung des Vorsprunges 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 vermieden, daß der Schwenkweg des Lagerteils 20 durch das Auftreffen des Anschlages 16 der Auslöseplatte 13 auf den Wegbegrenzer 8 begrenzt ist.FIGS. 4 and 5 show how the bearing
