Abstract

A laterally releasable jaw of a safety ski binding for fastening one end of a ski boot 9 has a binding housing 11, in which a release spring 14 is arranged which extends essentially in the longitudinal direction of the ski, is supported at one end on the binding housing 11 and with the other end applies a release force, having an essential component in the longitudinal direction of the ski, to a sole-holder 22, arranged towards the ski boot 9, in the direction away from the ski boot 9 in such a way that, if a predetermined lateral force exerted by the ski boot 9 is exceeded, the sole-holder 22 swivels out laterally about at least one essentially upright swivel axle and releases the ski boot 9. The release spring thereby exerts a force component directed downwards onto the sole-holder which is arranged on the binding housing 11 so as to be displaceable in height along an upright slide guide, with the result that the sole-holder 22 is pressed against the upper side of the ski boot sole 29. In this case, the slide guide 25, 26 has at least two portions 25', 26', 25'', 26'' which are inclined at such different angles to the line of action 27 of the force of the release spring that a centre of rotation M is formed which is arranged with spacing a above the line of action 27 of the force of the release spring. <IMAGE>

Description

Die Erfindung betrifft einen seitenauslösbaren Backen, insbesondere Vorderbacken einer Sicherheitsskibindung für die Halterung eines Endes eines Skisstiefels, welche außerdem einen das andere Ende des Skistiefels haltenden Backen, insbesondere einen Fersenbacken aufweist, der vorzugsweise auch in Skilängsrichtung über den Skistiefel eine elastische Anschubkraft auf den auslösbaren Backen ausübt, mit einem Bindungsgehäuse, in dem eine im wesentlichen in Skilängsrichtung verlaufende Auslösefeder angeordnet ist, die sich einseitig am Bindungsgehäuse abstützt und mit dem anderen Ende einen zum Skistiefel hin angeordneten, zwei Seitenschenkel und einen Niederhalter aufweisenden Sohlenhalter in Richtung vom Skistiefel weg mit einer eine wesentliche Komponente in Skilängsrichtung aufweisenden Auslösekraft entlang deren Wirkungslinie derart beaufschlagt, daß die Seitenschenkel bei Überschreiten einer vom Skistiefel ausgeübten vorbestimmten Seitenkraft wenigstens um eine im wesentlichen aufrechtstehende Kippachse seitlich auschwenken und den Skistiefel freigeben, wobei der Sohlenhalter am Bindungsgehäuse längs wenigstens einer im wesentlichen aufrechten Gleitführung höhenverschiebbar angeordnet ist, die so gegen die Wirkungslinie der Auslösefederkraft geneigt ist, daß die Auslösefeder eine nach unten gerichtete Kraftkomponente auf den Niederhalter ausübt, der dadurch gegen die Oberseite der Skistiefelsohle gedrückt ist. Ein derartiger seitenauslösbarer Backen, insbesondere Vorderbacken einer Sicherheitsskibindung ist beispielsweise aus der DE-38 25 682 A1 bekannt. Dieser bekannte Vorderbacken arbeitet weitgehend zufriedenstellend. Dabei muß jedoch die im wesentliche aufrechte Gleitführung so ausgesbildet bzw. gegen die Wirkungslinie der Auslösefederkraft geneigt sein, daß die nach unten auf den Sohlenhalter bzw. Niederhalter wirkende Kraftkomponente der Auslösefederkraft ausreicht, um die Reibung in der Gleitführung zu überwinden und den Niederhalter gegen die Skistiefelsohle nach unten zu drücken.The invention relates to a side-releasable cheek, in particular toe of a safety ski binding for holding one end of a ski boot, which also has a cheek holding the other end of the ski boot, in particular a heel cheek, which preferably also has an elastic pushing force on the releasable cheeks in the longitudinal direction of the ski boot exercises, with a binding housing, in which a substantially spring in the longitudinal direction of the trigger spring is arranged, which is supported on one side on the binding housing and with the other end arranged towards the ski boot, two side legs and a hold-down device in the direction away from the ski boot with one essential component in the longitudinal direction of the trigger force along its line of action so acted that the side legs when exceeding a predetermined lateral force exerted by the ski boot at least by a certain amount Finally swivel the upright tilting axis sideways and release the ski boot, the sole holder on the binding housing being arranged to be vertically displaceable along at least one essentially upright slide guide, which is inclined against the line of action of the release spring force in such a way that the release spring exerts a downward force component on the hold-down device, which thereby pressed against the top of the ski boot sole. Such a side-releasable jaw, in particular front jaws of a safety ski binding, is known for example from DE-38 25 682 A1. This known toe piece works largely satisfactorily. However, the essentially upright sliding guide must be trained or against the line of action of the release spring force must be inclined so that the force component of the release spring force acting downward on the sole holder or hold-down device is sufficient to overcome the friction in the sliding guide and to press the hold-down device against the ski boot sole.

Andererseits ist es jedoch erforderlich, zur Erzielung eines guten und deffinierten Seitenauslöseverhaltens des Backens die Gleitführungen nicht zu stark zu neigen, insbesondere wenn im Bereich der Gleitführungen auch die Kippachsen fürs seitliche Ausschwenken des Backens vorgesehen sind.On the other hand, it is necessary not to incline the slide guides too much in order to achieve a good and defined side release behavior of the jaw, especially if the tilting axes are also provided in the area of the slide guides for pivoting the jaw sideways.

Der Erfindung liegt nun die Aufgabe zugrunde, einen seitenauslösbaren Backen der eingangsgenannten Art zu schaffen, der bei einfachem Aufbau ein einwandfreies Niederdrücken des am Sohlenhalter vorgesehenen Niederhalters ermöglicht, ohne daß die Seitenauslösbarkeit des Backens beeinträchtigt wird.The invention is based on the object of providing a side-releasable jaw of the type mentioned at the outset which, with a simple construction, enables the downholder provided on the sole holder to be properly pressed down without the side releasability of the jaw being impaired.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Erfindungsgemäß weist also die Gleitführung Abschnitte auf, die gegen die Wirkungslinie der Auslösefederkraft unterschiedlich geneigt sind, so daß ein Momenten-Drehpol gebildet wird, dessen Abstand von der Wirkungslinie der Auslösefederkraft die Kraftkomponente festlegt, mit der der Niederhalter gegen die Oberseite einer Skistiefelsohle gedrückt wird. Hierdurch läßt sich eine Vergrößerung der Niederhaltekraft erreichen, ohne daß die Gleitführung insgesamt um einen zu großen Betrag gegen die Wirkungslinie der Auslösefederkraft geneigt werden, muß Auf diese Weise läßt es sich also erreichen, die Gleitführung, insbesondere im Bereich der Kippachse für das seitliche Ausschwenken des Backens nur relativ wenig gegen die Wirkungslinie der Auslösefederkraft zu neigen, so daß ein einwandfreies seitliches Auslösen sichergestellt werden kann.According to the invention, therefore, the sliding guide has sections which are inclined differently against the line of action of the release spring force, so that a torque rotary pole is formed, the distance from the line of action of the release spring force defining the force component with which the hold-down device is pressed against the top of a ski boot sole. In this way, an increase in the hold-down force can be achieved without the slide guide as a whole being inclined too much against the line of action of the release spring force So achieve to tend the sliding guide, especially in the region of the tilt axis for the lateral pivoting of the jaw relatively little against the line of action of the release spring force, so that a perfect lateral release can be ensured.

An dieser Stelle soll auf die EP-A-0 311 832 hingewiesen werden. Diese stellt einen weiteren Stand der Technik nach dem Oberbegriff des Anspruches 1 dar. Die in dieser Schrift von den Abstütz- und Kippflächen gebildete Gleitführung besitzt jedoch keine zwei Abschnitte die unterschiedlich gegen die Wirkungslinie der Auslösefederkraft geneigt sind wie vom vorliegenden Vorschlag gefordert wird. Vielmehr ist die Lage der Gleitführung angebende Kippachse im ersten Ausführungsbeispiel der EP-A-0 311 832 durchgehend vertikal und in den übrigen Ausführungsformen einheitlich schräg verlaufend ausgebildet.At this point, reference should be made to EP-A-0 311 832. This represents a further state of the art according to the preamble of claim 1. However, the sliding guide formed in this document by the support and tilting surfaces does not have two sections which are inclined differently against the line of action of the release spring force, as is required by the present proposal. Rather, in the first embodiment of EP-A-0 311 832, the position of the tilting axis indicating the sliding guide is continuously vertical and, in the other embodiments, uniformly inclined.

Wird die Gleitführung nach dem vorliegenden Vorschlag beispielsweise in zwei gradlinige Abschnitte aufgeteilt, von denen der obere wenig und der untere relativ stark geneigt ist, so stützt sich der Sohlenhalter infolge der nach vorne gerichteten elastischen Anschubkraft bei eingesetztem Skistiefel im wesentlichen am oberen Abschnitt der Gleitführung ab, der dann eine nur wenig geneigte Kippachse fürs Seitenauslösen bildet, wodurch das seitliche Auslösen des Backens begünstigt wird.If, according to the present proposal, the sliding guide is divided, for example, into two straight sections, of which the upper one is slightly inclined and the lower one is relatively strongly inclined, the sole holder is supported essentially on the upper section of the sliding guide due to the forward elastic pushing force when the ski boot is inserted , which then forms a tilting axis that is only slightly inclined for side release, which favors the lateral release of the jaw.

Ferner ist es hierbei möglich, die Auslösefeder im wesentlichen parallel zur Skilängsachse anzuordnen, so daß die Einstellschraube für die Auslösefeder besser zugänglich ist und die Einstellung der Auslösekraft dadurch erleichtert wird, da die den Sohlenniederhalter nach unten beaufschlagende Kraft durch die Bildung eines Momenten-Drehpols erzeugt wird.Furthermore, it is possible to arrange the release spring essentially parallel to the longitudinal axis of the ski, so that the adjusting screw for the release spring is more accessible and the adjustment of the release force is thereby facilitated, since the force acting on the sole retainer downwards is generated by the formation of a torque rotating pole becomes.

Bei einer besonders vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß die Gleitführung als Kreisbogen ausgebildet ist, dessen Krümmungsmittelpunkt D den Drehpol bildet.In a particularly advantageous development of the invention, it is provided that the sliding guide is designed as an arc, the center of curvature D of which forms the center of rotation.

Hierdurch wird eine besonders gute Gleitführung des Sohlenhalters erreicht, wobei gleichzeitig eine im wesentlichen auf der Skioberfläche senkrecht stehende Kippachse für das Seitenauslösen realisiert werden kann.In this way, a particularly good sliding guidance of the sole holder is achieved, while at the same time a tilt axis for the lateral release, which is essentially perpendicular to the ski surface, can be realized.

Um eine einwandfreie Funktion des Backens bei gleichzeitiger hoher Lebensdauer zu erreichen, ist erfindungsgemäß vorgesehen, daß die Gleitführung des Sohlenhalters am Bindungsgehäuse von einer Gleitleiste und einer entsprechenden Gleitführungsfläche gebildet ist, wobei zumindest ein Abschnitt der Gleitleiste aus einem Material mit erhöhter Verschleißfestigkeit, vorzugsweise aus Metall besteht.
Dabei ist es zweckmäßig, wenn der obere Abschnitt der Gleitleiste, der eine geringere Neigung gegen die Wirkunglinie der Auslösefederkraft aufweist als der untere Abschnitt aus verschleißfestem Material besteht. Hierdurch wird eine besonders hohe Lebensdauer des zusätzlich als Kippgelenk belasteten Abschnitts der Gleitleiste erreicht.In order to achieve a perfect function of the baking with a long service life, the invention provides that the slide guide of the sole holder on the binding housing is formed by a slide bar and a corresponding slide guide surface, at least a section of the slide bar being made of a material with increased wear resistance, preferably of metal.
It is expedient if the upper section of the slide bar, which has a lower inclination to the line of action of the release spring force than the lower section, consists of wear-resistant material. As a result, a particularly long service life of the section of the slide strip which is additionally loaded as a tilting joint is achieved.

Es ist jedoch auch möglich, daß die gesamte Gleitleiste aus verschleißfestem Material besteht.However, it is also possible for the entire slide strip to be made of wear-resistant material.

Eine weitere Ausgestaltung der Erfindung zeichnet sich dadurch aus, daß zwei symmetrisch zur senkrecht auf der Skioberfläche stehenden Skilängsmittelebene angeordnete Gleitführungen mit je einer Gleitleiste und zugeordneter Gleitführungsfläche vorgesehen ist, wobei die Kippachsen für das seitliche Ausschwenken des Sohlenhalters im Bereich der Gleitleisten angeordnet sind.A further embodiment of the invention is characterized in that two sliding guides are arranged symmetrically to the longitudinal center plane of the ski standing vertically on the ski surface, each with a sliding strip and an associated sliding guide surface, the tilting axes being arranged in the region of the sliding strips for the lateral pivoting out of the sole holder.

Bei einer besonders vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß im Bereich jeder Gleitführung zwischen dem Bindungsgehäuse un dem Sohlenhlater ein Zwischenstück angeordnet ist, daß mit dem Sohlenhalter die Gleitführung und mit dem Bindungsgehäuse ein Kippgelenk bildet, dessen Kippachse senkrecht zur Wirkunglinie der Auslösefederkraft angeordnet ist.In a particularly advantageous development of the invention it is provided that an intermediate piece is arranged in the region of each slide guide between the binding housing and the sole holder, that the slide guide forms with the sole holder and a tilting joint with the binding housing, the tilt axis of which is arranged perpendicular to the line of action of the release spring force.

Durch das erfindungsgemäß vorgesehene Zwichenstück im Bereich jeder Gleitführung läßt sich das Kippgelenk zwischen dem Sohlenhalter und dem Bindungsgehäuse optimal in Bezug auf die Wirkungslinie der Auslösefederkraft ausrichten, ohne daß auf die erfindungsgemäße vorteilhafte Ausgestaltung der Gleitführungsflächen verzichtet werden muß. Insbesondere wenn die Gleitführungsflächen kreisbogenförmig ausgebildet sind, läßt sich eine Niederdrückbewegung des Sohlenhalters erreichen, die praktisch keinen unerwünschten Einfluß auf die Auslösekraft hat, da infolge der schwenkenden Abwärtsbewegung des Sohlenhalters die eingestellte Länge der Auslösefeder praktisch nicht geändert wird.By means of the intermediate piece provided according to the invention in the region of each sliding guide, the tilt joint between the sole holder and the binding housing can be optimally aligned with respect to the line of action of the release spring force without that the advantageous embodiment of the sliding guide surfaces according to the invention must be dispensed with. In particular, if the sliding guide surfaces are formed in a circular arc, a depressing movement of the sole holder can be achieved, which has practically no undesirable influence on the triggering force, since the set length of the trigger spring is practically not changed due to the pivoting downward movement of the sole holder.

Dabei ist es besonders vorteilhaft, wenn das Zwischenstück zumindest in der Gleitführung zugeordneten Bereich aus einem Material mit vermindertem Gleitreibungskoeffizienten besteht oder eine die Gleitreibung verringernde Beschichtung trägt.It is particularly advantageous if the intermediate piece, at least in the region assigned to the sliding guide, consists of a material with a reduced sliding friction coefficient or has a coating that reduces the sliding friction.

Nach Fig. 1 ist auf einem Ski 10 das Bindungsgehäuse 11 eines Vorderbackens mit nicht dargestellten Mitteln befestigt. An einem in Skilaufrichtung gesehen hinteren Fortsatz 11' des Bindungsgehäuses 11 ist eine Gleitplatte 12 vorgesehen, durch die der vordere Bereich der Sohle 29 eines in den Backen eingesetzten Skistiefels 9 von unten abgestützt wird.1, the binding housing 11 of a toe is fastened on a ski 10 by means not shown. On a rear extension 11 'of the binding housing 11, as seen in the direction of skiing, a sliding plate 12 is provided, by means of which the front region of the sole 29 of a ski boot 9 inserted in the cheeks is supported from below.

Im vorderen Bereich des Bindungsgehäuses 11 ist ein zur Skilängsrichtung schräg verlaufender Auslösefeder-Aufnahmeraum 13 vorgesehen, innerhalb dessen eine Auslösefeder 14 angeordnet ist, die sich mit hinteren Ende an einer Ringwand 15 des Bindungsgehäuses 11 und mit ihrem vorderen Ende an einem axial verstellbaren Widerlager 16 abgestützt ist. Am Widerlager 16 ist eine Zugstange 17 befestigt, die an ihrem vorderen, vom Widerlager 16 abgewandten und sich durch eine Öffnung 18 in der Ringwand 15 des Bindungsgehäuses 11 hindurcherstreckenden Ende ein Befestigungsauge 20 aufweist.Provided in the front area of the binding housing 11 is a release spring receiving space 13 which runs obliquely to the longitudinal direction of the ski, within which a release spring 14 is arranged, which is supported at the rear end on an annular wall 15 of the binding housing 11 and at its front end on an axially adjustable abutment 16 is. A tie rod 17 is fastened to the abutment 16 and has a fastening eye 20 on its front end facing away from the abutment 16 and extending through an opening 18 in the ring wall 15 of the binding housing 11.

Durch das Befestigungsauge 20, daß in einer Ausnehmung 21 eines Sohlenhalters 22 angeordnet ist, erstreckt sich ein Befestigungsbolzen 19, der in entsprechende Bohrungen des Sohlenhalters 22 eingesetzt ist, so daß der Sohlenhalter 22 von der Auslösefeder 14 über das Widerlager 16 und durch die Zugstange 17 gegen das Bindungsgehäuse 11 in Anlage gehalten wird.A fastening bolt 19 extends through the fastening eye 20, which is arranged in a recess 21 of a sole holder 22, and is inserted into corresponding bores in the sole holder 22, so that the sole holder 22 extends from the release spring 14 via the abutment 16 and through the pull rod 17 is held against the binding housing 11.

Der Sohlenhalter 22, der einen Niederhalter 23 und zwei Seitenschenkel 24, von denen nur einer dargestellt ist, aufweist, ist mittels zweier in Bezug auf den Ski im wesentlichen aufrechtstehender Gleitleisten 25 am Bindungsgehäuse 11 abgestützt, wobei die Gleitleisten 25 mit entsprechenden Gleitführungen 26 in Eingriff stehen.The sole holder 22, which has a hold-down 23 and two side legs 24, only one of which is shown, is supported on the binding housing 11 by means of two slide strips 25 which are essentially upright with respect to the ski, the slide strips 25 engaging with corresponding slide guides 26 stand.

Die Gleitleisten 25 bzw. -Führungen 26 sind dabei symmetrisch zur Skilängsachse bzw. symmetrisch zur Wirkungslinie 27 der Auslösefeder 14 angeordnet, bilden Kippflächen bzw. Gegenkippflächen und legen die Schwenkachsen fest, um die der Sohlenhalter 22 verschwenkt wird, wenn ein in den Vorderbacken eingesetzter Skistiefel 9 eine die Auslösekraft übersteigende Kraft auf einen der Seitenschenkel 24 des Sohlenhalters 22 ausübt.The slide strips 25 and guides 26 are arranged symmetrically to the longitudinal axis of the ski or symmetrically to the action line 27 of the release spring 14, form tilting surfaces or counter-tilting surfaces and define the pivoting axes about which the sole holder 22 is pivoted when a ski boot inserted in the front jaws 9 exerts a force exceeding the release force on one of the side legs 24 of the sole holder 22.

Die Gleitleisten 25 bzw. -Führungen 26 weisen einen ersten oberen geraden Abschnitt 25' bzw. 26' und einen zweiten, unteren geraden Abschnitt 25'', 26'' auf. Die ersten geraden Abschnitte 25', 26' schließen dabei mit der senkrechten zur Wirkungslinie 27 der Auslösefeder einen ersten Winkel α1 ein, der kleiner ist, als ein Winkel α2, den die zweiten geraden Abschnitte 25'' und 26'' mit der senkrechten zur Wirkungslinie 27 der Auslösefeder einschließen. Dabei können z.B. in den Abschnitten 26' der Gleitführungen 26 Freischneidungen 26''' vorgesehen sein.The slide strips 25 or guides 26 have a first upper straight section 25 'or 26' and a second, lower straight section 25 '', 26 ''. The first straight sections 25 ', 26' enclose a first angle α1 with the line perpendicular to the line of action 27 of the release spring, which is smaller than an angle α2 which the second straight sections 25 '' and 26 '' with the perpendicular to Include line of action 27 of the trigger spring. Here, e.g. in the sections 26 'of the slide guides 26, free cuts 26' '' can be provided.

Aufgrund der gegen die senkrechte der Wirkungslinie 27 der Auslösefeder 14 geneigten Gleitleisten 25 bzw. -Führungen 26 übt die Auslösefeder 14 eine nach unten gerichtete Kraft auf den Sohlenhalter 22 aus, so daß der Niederhalter 23 bei eingesetztem Skistiefel 9 von oben gegen die Skistiefelsohle 29 gedrückt wird, so daß diese zwischen der Gleitplatte 12 und dem Niederhalter 23 eingespannt ist.Due to the inclined against the vertical line of action 27 of the release spring 14 slide rails 25 or guides 26, the release spring 14 exerts a downward force on the sole holder 22, so that the hold-down device 23 is pressed against the ski boot sole 29 when the ski boot 9 is inserted is so that it is clamped between the slide plate 12 and the hold-down 23.

Aufgrund der unterschiedlich gegen die Senkrechte zur Wirkungslinie 27 der Auslösefeder 14 geneigten Abschnitte 25', 26' bzw. 25'', 26'' die, je nach dem im Bereich welcher dieser Abschnitte der Sohlenhalter 22 vorzugsweise am Bindungsgehäuse abgestützt wird, zwei verschieden gerichtete Kippachsen bilden, wird ein Momentan-Drehpol M gebildet, der einen Abstand a von der Wirkungslinie 27 der Auslösefeder 14 aufweist. Hierdurch entsteht das den Sohlenhalter 22 nach unten beaufschlagende Drehmoment.Due to the differently inclined to the line of action 27 of the release spring 14 sections 25 ', 26' and 25 '', 26 '' which, depending on which in the area of which sections of the sole holder 22 is preferably supported on the binding housing, two differently directed Form tilting axes, a momentary rotary pole M is formed, which is at a distance a from the line of action 27 of the release spring 14. This creates the downward torque on the sole holder 22.

So lange in die entsprechende Skibindung kein Skistiefel eingesetzt ist, wird der Sohlenhalter 22 von der Auslösefeder 14 gegen einen unteren Anschlag gedrückt, der beispielsweise von der Oberseite des hinteren Fortsatzes 11' des Bindungsgehäuses 11 gebildet werden kann. Dabei wird der Sohlenhalter 22 im wesentlichen entlang der oberen geraden Abschnitte 25', 26' der Gleitleisten 25 bzw. -Führungen 26 am Bindungsgehäuse 11 abgestützt.As long as no ski boot is inserted into the corresponding ski binding, the sole holder 22 is pressed by the release spring 14 against a lower stop, which can be formed, for example, by the top of the rear extension 11 'of the binding housing 11. The sole holder 22 is supported essentially along the upper straight sections 25 ′, 26 ′ of the slide strips 25 or guides 26 on the binding housing 11.

Zum Einsetzen des Skistiefels 9 wird dieser mit dem vorderen Abschnitt der Skistiefelsohle 29 in den Spalt zwischen dem Niederhalter 23 und der Gleitplatte 12 eingeführt, woraufhin die Skistiefelsohle 29 dann um die Gleitplatte 12 in ihre skiparallele Stellung geschwenkt wird. Dabei gelangt die Oberseite des vorderen Ende der Skistiefelsohle 29 mit dem Niederhalter 23 in Eingriff und schiebt diesen und damit den Sohlenhalter 22 entgegen dem von der Auslösefeder auf den Sohlenhalter 22 ausgeübten Drehmoment entlang der Gleitführungen 26 nach oben bis der Skistiefel 9 vollständig in die Bindung eingesetzt ist.To insert the ski boot 9, it is inserted with the front section of the ski boot sole 29 into the gap between the hold-down device 23 and the slide plate 12, whereupon the ski boot sole 29 is then pivoted about the slide plate 12 into its ski-parallel position. The upper side of the front end of the ski boot sole 29 engages with the hold-down device 23 and pushes this and thus the sole holder 22 upwards against the torque exerted by the release spring on the sole holder 22 along the slide guides 26 until the ski boot 9 is fully inserted into the binding is.

Wird nun während des Skifahrens vom vorderen Ende der Skistiefelsohle 29 eine nach oben gerichtete Kraft auf den Niederhalter 23 ausgeübt, so wird der Sohlenhalter 22 nach oben gegen die von der Auslösefeder 14 bewirkte nach unten gerichtete Kraft bzw. gegen das Drehmoment um den Momenten-Drehpol M nach oben bewegt. Sobald die nach oben gerichtete Kraft wieder wegfällte, drückt der Niederhalter 23 die Skitstiefelsohle wieder gegen die Gleitplatte 12.If an upward force is now exerted on the hold-down device 23 from the front end of the ski boot sole 29 during skiing, the sole holder 22 becomes upward against the downward force caused by the release spring 14 or against the torque around the torque pivot M moved up. As soon as the upward force ceased to apply, the hold-down device 23 presses the ski boot sole against the sliding plate 12 again.

Hierbei ist es besonders vorteilhaft, daß die untern Abschnitte 25'', 26'' der Gleitleisten 25 bzw. -Führungen 26 um einen größeren Winkel α 2 gegen die senkrechte zur Wirkungslinie 27 der Auslösefeder 14 geneigt ist. Auf diese Weise wird ein Hängenbleiben des Sohlenhalters 22 in einer oberen Stellung in Folge von erhöhter Reibung zwischen den Gleitleisten 25 und -Führungen 26 verhindert, da der Reibungseinfluß durch die größere Neigung der unteren Abschnitte 25'', 26'' wesentlich verringert wird.It is particularly advantageous here that the lower sections 25 ″, 26 ″ of the slide strips 25 or guides 26 around a larger angle α 2 is inclined to the vertical to the line of action 27 of the trigger spring 14. In this way, the sole holder 22 is prevented from getting caught in an upper position as a result of increased friction between the slide strips 25 and guides 26, since the influence of friction is substantially reduced by the greater inclination of the lower sections 25 ″, 26 ″.

Um ein unerwünscht weites Ausweichen des Sohlenhalters 22 nach oben zu verhindern, kann für den Sohlenhalter 22 ein nicht dargestellter oberer Anschlag vorgesehen sein, der gegebenenfalls als Kippkante für einen auch nach oben auslösbaren Vorderbacken dienen kann.In order to prevent an undesirably wide deflection of the sole holder 22 upwards, an upper stop (not shown) can be provided for the sole holder 22, which can optionally serve as a tilting edge for a front jaw which can also be released upwards.

Um die Lebensdauer des erfindungsgemäßen seitenauslösbaren Backen zu vergrößern und gleichzeitig die Reibung zwischen den Gleitleisten 25 und -Führungen 26 geeignet zu beeinflussen, können die Gleitleisten 25 und/oder die Gleitführungen 26 aus Metall ausgebildet sein.In order to increase the service life of the side-releasable jaw according to the invention and at the same time suitably influence the friction between the slide strips 25 and guides 26, the slide strips 25 and / or the slide guides 26 can be made of metal.

Bei dem Ausführungsbeispiel nach Fig. 3 sind die Gleitführungen 26 kreisbogenförmig ausgebildet, wobei der Krümmungsmittelpunkt D in einem Abstand a von der Wirkungslinie 27 der Auslösefeder 14 angeordnet ist. Die am Sohlenhalter 22 angeordneten Gleitleisten 25 weisen eine den Gleitführungen 26 entsprechende konkave Kreisbogenform auf.In the exemplary embodiment according to FIG. 3, the slide guides 26 are designed in the form of a circular arc, the center of curvature D being arranged at a distance a from the line of action 27 of the release spring 14. The slide strips 25 arranged on the sole holder 22 have a concave circular arc shape corresponding to the slide guides 26.

Durch den Versatz des Krümmungsmittelpunktes D der kreisbogenförmigen Gleitführungen 26 bzw. Gleitleisten 25 um den Abstand a gegenüber der Wirkungslinie 27 der Auslösefeder 14 wird ein Hebelarm gebildet, so daß die Auslösefederkraft ein auf den Sohlenhalter 22 wirkendes Drehmoment um den Punkt D erzeugt, daß den Sohlenhalter 22 in Richtung auf den Ski 10 bewegt.By offset of the center of curvature D of the circular arc-shaped slide guides 26 or slide strips 25 by the distance a from the line of action 27 of the release spring 14, a lever arm is formed, so that the release spring force generates a torque acting on the sole holder 22 around the point D that the sole holder 22 moved towards the ski 10.

Aufgrund dieses Drehmomentes kann der am Sohlenhalter 22 vorgesehene Sohlenniederhalter 23 bei eingesetztem Skistiefel eine von oben auf die Skistiefelsohle wirkende Haltekraft ausüben und einen eingesetzten Skistiefel damit in Höhenrichtung spielfrei in der Bindung halten.On account of this torque, the sole hold-down device 23 provided on the sole holder 22 can exert a holding force acting on the ski boot sole from above when the ski boot is inserted, and thus hold an inserted ski boot without play in the binding in the vertical direction.

Bei dem seitenauslösbaren Backen nach Fig. 3 bilden die Gleitleisten (26) bzw. -Führungen 26 widerrum die Kippfläche bzw. Kippgegenfläche, um die der Sohlenhalter 22 beim seitlichen Auslösen gegen die Auslösefederkraft verschwenkt.3, the slide strips (26) or guides 26 in turn form the tilting surface or tilting counter surface, about which the sole holder 22 pivots against the release spring force when it is released laterally.

Nach den Fig. 4 bis 6 sind an einem seitenauslösbaren Backen widerum kreisbogenförmig ausgebildete Gleitführungen vorgesehen, die von einer am Sohlenhalter 22 ausgebildeten Gleitführungsnut 35 und einer Gleitleiste 36 gebildet werden. Die Gleitleiste 36 ist dabei an einem Zwischenstück 28 vorgesehen, daß zwischen den Sohlenhalter 22 und das Bindungsgehäuse 11 eingesetzt ist. An seiner in Skilaufrichtung vorderen Kante weist das Zwischenstück 28 eine Kippleiste 37 auf, die vorzugsweise in einer entsprechenden Nut 38 angeordnet ist, welche eine Kippfläche am Sohlenhalter 11 bildet, während die Kippgegenfläche an der Kippleiste 37 des Zwischenstücks 28 vorgesehen ist.4 to 6 are provided on a side-releasable jaws, in turn, circular-arc-shaped slide guides, which are formed by a slide guide groove 35 formed on the sole holder 22 and a slide bar 36. The slide bar 36 is provided on an intermediate piece 28 that is inserted between the sole holder 22 and the binding housing 11. On its front edge in the direction of skiing, the intermediate piece 28 has a tilting bar 37, which is preferably arranged in a corresponding groove 38, which forms a tilting surface on the sole holder 11, while the counter-tilting surface is provided on the tilting bar 37 of the intermediate piece 28.

Wie besonders deutlich in Fig. 4 zu erkennen, ist die durch die Kippleiste 37 und die Nut 38 festgelegte Kippachse senkrecht zur Wirkungslinie 27 der Auslösefeder 14 angeordnet, so daß der Sohlenhalter 22 beim seitlichen Auslösen um eine deffinierte, senkrechte Kippachse geschwenkt wird.As can be seen particularly clearly in FIG. 4, the tilt axis defined by the tilting bar 37 and the groove 38 is arranged perpendicular to the line of action 27 of the release spring 14, so that the sole holder 22 is pivoted about a defined, vertical tilt axis during the lateral release.

Die getrennte Anordnung von Kippleiste 37 und Gleitleiste 36 mittels eines Zwischenstücks 28 ermöglicht es, den Krümmungsradius der kreisbogenförmigen Gleitführungen sowie den Abstand a des Krümmungsmittelpunktes von der Wirkungslinie 27 der Auslösefeder 14 frei zu wählen, ohne daß dadurch das Auslöseverhalten des Sohlenhalters beeinträchtigt wird.The separate arrangement of tilting bar 37 and sliding bar 36 by means of an intermediate piece 28 enables the radius of curvature the arcuate sliding guides and the distance a of the center of curvature from the line of action 27 of the release spring 14 can be freely selected without the release behavior of the sole holder being impaired thereby.
