Abstract

A safety ski binding for holding the tip of a ski boot and capable of releasing sideways has two side jaws (13, 14) which hold the ski boot at the sides; a sole hole-down member (15), and a release spring (11) which extends substantially in the longitudinal direction of the ski. The release spring is braced at one of its ends against the binding housing (12) which is fixedly mounted to the ski and acts at its other end on the sideways release mechanism which a forwardly directed force. The sole hold-down member (15), the side jaws (13, 14), the sideways release mechanism and the point of action (16) of the release spring (11) are arranged on a carrier (18) which is pivotable upwardly relative to the binding housing (12) about a transverse axle (17). The transverse axle (17) is located at a distance (A) above the line of action (19) of the release spring (11) such that a predetermined hold-down force originating from the release spring (11) acts from the upper side on the sole (42) of the ski boot.

Description

Die Erfindung betrifft eine seitenauslösbare Sicherheitsskibindung, insbesondere für die Halterung der Skistiefelspitze, mit zwei den Skistiefel seitlich haltenden Seitenbacken, einem Sohlenniederhalter und einer sich im wesentlichen in Skilängsrichtung erstreckenden Auslösefeder, welche mit ihrem einen Ende am skifesten Bindungsgehäuse abgestützt ist und mit ihrem anderen Ende den Seitenauslösemechanismus mit einer vom Skistiefel weg, insbesondere nach vorn gerichteten Kraft beaufschlagt, wobei der Sohlenniederhalter und die Seitenbacken an einem relativ zum Bindungsgehäuse um eine Querachse hochschwenkbaren Tragteil angeordnet sind.The invention relates to a safety ski binding that can be released from the side, in particular for holding the tip of the ski boot, with two side jaws holding the ski boot to the side, a sole hold-down device and a release spring that extends essentially in the longitudinal direction of the ski, which is supported at one end on the ski-fixed binding housing and at the other end Side release mechanism is subjected to a force directed away from the ski boot, in particular forward, the sole hold-down device and the side jaws being arranged on a support part which can be swiveled up about a transverse axis relative to the binding housing.

Es ist bereits ein Auslösevorderbacken für Skibindungen bekannt (AT-PS 300 630), bei dem an einem seitlich auslösbaren Vorderbacken ein Sohlenniederhalter angeordnet ist, der gegen die Vorspannung einer Feder federnd nach oben ausweichen kann. Hierdurch soll verhindert werden, daß z.B. bei einer Schneezwischenlage zwischen Schuh und Ski der Schuh abnormale Beanspruchungen auf die Bindung und den Ski ausübt und so die funktionellen Eigenschaften der Bindung verändert. Nachteilig an dieser bekannten Skibindung ist das Erfordernis einer besonderen Niederhaltefeder.A release front jaw for ski bindings is already known (AT-PS 300 630), in which a sole hold-down device is arranged on a side release front jaw, which can deflect upwards against the bias of a spring. This is to prevent e.g. If there is an intermediate layer of snow between the shoe and the ski, the shoe exerts abnormal stresses on the binding and the ski and thus changes the functional properties of the binding. A disadvantage of this known ski binding is the need for a special hold-down spring.

Es ist auch schon bekannt (DE-OS 3 230 186), die auf den Sohlenniederhalter wirkende federnde Niederhaltekraft von der sich in Skilängsrichtung erstreckenden Auslösefeder abzuleiten, doch ist es hierzu erforderlich, das eine Ende der Auslösefeder auf den Sohlenniederhalter und das andere Ende der Auslösefeder auf den Seitenauslösemechanismus wirken zu lassen. Hierzu muß auch das vordere Ende der Auslösefeder einschließlich der sie abstützenden Bauteile beweglich sein, was konstruktiv und auch betrieblich einen Nachteil darstellt.It is also already known (DE-OS 3 230 186) to derive the resilient hold-down force acting on the sole hold-down device from the release spring extending in the longitudinal direction of the ski, but for this purpose it is necessary that one end of the release spring on the sole hold-down device and the other end of the release spring to act on the side trigger mechanism. For this purpose, the front end of the release spring including the components supporting it must also be movable, which is a disadvantage in terms of construction and operation.

Bei einer gattungsgemäßen seitenauslösbaren Sicherheitsskibindung (FR-A 2 523 857, FR-A 2 385 418) wird die niederhaltende Kraft für den Sohlenhalter von der Auslösefeder über einen besonderen Hebel- bzw. Kulissenmechanismus auf den Sohlenhalter übertragen. Es ist somit ein besonderer Kraftübertragungsmechanismus zusätzlich zu den Bauelementen für die Übertragung der Seitenauslösekräfte erforderlich. Eine ständige Niederhaltekraft, wie sie erwünscht wäre, wird auf die Schuhsohle nicht ausgeübt, indem ein Höhenverstellmechanismus für den eigentlichen Sohlenniederhalter vorgesehen ist, mittels dessen der Sohlenniederhalter so verstellt wird, daß er normalerweise keine Niederhaltekraft auf die Schuhsohle ausübt.With a generic side-release safety ski binding (FR-A 2 523 857, FR-A 2 385 418), the holding-down force for the sole holder is transferred from the release spring to the sole holder via a special lever or link mechanism. A special power transmission mechanism is therefore required in addition to the components for the transmission of the side release forces. A constant hold-down force, as would be desired, is not exerted on the shoe sole by providing a height adjustment mechanism for the actual sole hold-down device, by means of which the sole hold-down device is adjusted such that it normally does not exert any hold-down force on the shoe sole.

Die Aufgabe der Erfindung besteht darin, die Niederhaltekraft für den Sohlenniederhalter ohne besondere Kraftübertragungsmittel zwischen der Auslösefeder und dem Sohlenniederhalter auf einfache Weise bereitzustellen.The object of the invention is to provide the hold-down force for the sole hold-down device in a simple manner without special force transmission means between the release spring and the sole hold-down device.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß auch der Seitenauslösemechanismus und der Angriffspunkt der Auslösefeder am Seitenauslösemechanismus, an dem relativ zum Bindungsgehäuse um die Querachse hochschwenkbaren Tragteil angeordnet sind und daß die Querachse sich in einem solchen Abstand oberhalb der Wirkungslinie der Auslösefeder befindet, daß von der Oberseite her eine von der Auslösefeder herrührende, vorbestimmte, federnd nachgiebige Niederhaltekraft auf die Skistiefelsohle einwirkt.To achieve this object, the invention provides that the side release mechanism and the point of application of the release spring on the side release mechanism are arranged on the support part which can be pivoted up relative to the binding housing about the transverse axis, and that the transverse axis is located at a distance above the line of action of the release spring that a predetermined, resilient hold-down force originating from the release spring acts on the ski boot sole from the top.

Das Wesen der Erfindung besteht demnach darin, daß die einseitig am Bindungsgehäuse abgestützte Auslösefeder mit dem anderen wirksamen Ende unmittelbar den im hochschwenkbaren Tragteil angeordneten Seitenauslösemechanismus beaufschlagt, wodurch automatisch und ohne besondere Hebel-oder Kulissenmechanismen die gewünschte Niederhaltekraft für den Sohlenhalter erzielt wird. Allein die besondere Aufteilung der verschiedenen Bauteile der Erfindung auf feststehende und bewegliche Bindungsteile führt somit bei geringem Herstellungsaufwand zur Ausnutzung der Auslösefederkraft außer für die Seitenauslösung auch zur Erzielung der Niederhaltekraft am Sohlenniederhalter. Außerdem wird erfindungsgemäß ständig eine definierte Niederhaltekraft auf die Schuhsohle ausgeübt, so daß auch bei Einstellung von Schuhsohlen unterschiedlicher Dicke stets die gleichen Auslöseverhältnisse vorliegen, ohne daß irgendein Höhenverstellmechanismus betätigt werden muß.The essence of the invention is therefore that the release spring supported on one side on the binding housing with the other effective end directly acts on the side release mechanism arranged in the pivoting support part, whereby the desired hold-down force for the sole holder is achieved automatically and without special lever or link mechanisms. Only the special division of the various components of the invention into fixed and movable binding parts thus leads to the use of the release spring force with little manufacturing effort, in addition to the side release, also to achieve the hold-down force on the sole hold-down device. In addition, according to the invention, a defined hold-down force is constantly exerted on the shoe sole, so that even when shoe soles of different thicknesses are adjusted, the same triggering conditions are always present without having to operate any height adjustment mechanism.

Eine bevorzugte Dimensionierung des Abstandes zwischen der Querachse und der Wirkungslinie der Auslösefeder unter Berücksichtigung des Abstandes des Sohlenniederhalters von der Querachse führt dazu, daß die vorbestimmte Niederhaltekraft zwischen 100 und 300 N, bevorzugt 150 und 250 N und insbesondere bei etwa 200 N liegt.A preferred dimensioning of the distance between the transverse axis and the line of action of the release spring, taking into account the distance of the sole hold-down from the transverse axis, leads to the fact that the predetermined hold-down force is between 100 and 300 N, preferably 150 and 250 N and in particular approximately 200 N.

Aufgrund der erfindungsgemäßen Ausbildung finden je nach dem Grad der Hochschwenkung des Sohlenniederhalters zwischen der Auslösefeder und dem Tragteil sowie dem Bindungsgehäuse Relativbewegungen statt, welche es vorteilhaft erscheinen lassen, daß um die Auslösefeder, deren Widerlager und Befestigungsenden ausreichende Spielräume vorgesehen sind, damit die am nicht mitbewegten Bindungsgehäuse abgestütze Auslösefededer sowie ihre Widerlager und Befestigungsenden die beim begrenzten Hochschwenken des Tragteils auftretenden Verschiebungen und Schwenkungen ungehindert mitmachen können.Due to the design according to the invention, depending on the degree of pivoting of the sole hold-down device, relative movements take place between the release spring and the supporting part and the binding housing, which make it appear advantageous that sufficient clearance is provided around the release spring, its abutment and fastening ends, so that those not moved along Binding housing supported release spring as well as their abutments and fastening ends which can take part in the displacements and swivels occurring when the supporting part is swiveled up for a limited time.

Der Schwenkbereich des Tragteils relativ zum Bindungsgehäuse muß nicht besonders groß sein. Es genügt für alle praktsich vorkommenden Fällle, wenn der Schwenkbereich des Tragteils nach oben so begrenzt ist, daß die Höhenbeweglichkeit des Sohlenniederhalters 2 bis 8 mm, insbesondere 3 bis 7 mm und bevorzugt 4 bis 6 mm beträgt.The pivoting range of the support part relative to the binding housing does not have to be particularly large. It is sufficient for all practically occurring cases if the pivoting range of the support part is limited upwards so that the height of the sole hold-down device is 2 to 8 mm, in particular 3 to 7 mm and preferably 4 to 6 mm.

Um die Auslösefeder problemlos unter der erfindungsgemäßen Querachse hindurchführen zu können, ist es zweckmäßig, wenn die Auslösefeder von hinten nach vorn leicht nach unten abfallend geneigt ist. Insbesondere soll die Anordnung so sein, daß der Neigungswinkel der Wirkungslinie relativ zur Horizontalen 2 ° bis 8 ° und insbesondere etwa 5 0 beträgt.In order to be able to easily pass the release spring under the transverse axis according to the invention, it is expedient if the release spring is inclined slightly downwards from the rear to the front. In particular, the arrangement should be such that the angle of inclination of the line of action relative to the horizontal is 2 ° to 8 ° and in particular approximately 50.

Besonders bevorzugt ist es, wenn der Seitenauslösemechanismus aus zwei am Tragteil ausgebildeten seitlichen. vertikalen Kippkanten und damit zusammenwirkenden Kippflächen eines Kippbackens besteht. Bei einer derartigen Anordnunng sind sowohl. der Sohlenniederhalter als auch die Seitenbacken formschlüssig mit dem Kippbacken verbunden. Grundsätzlich könnte aber auch der Sohlenniederhalter formschlüssig am Tragteil angebracht sein, während nur die Seitenbacken gegen die Kraft der Auslösefeder ausschwenkbar sind.It is particularly preferred if the side release mechanism consists of two side release mechanisms formed on the support part. vertical tipping edges and thus too interacting tilting surfaces of a tilting jaw. With such an arrangement are both. the sole hold-down and the side jaws are positively connected to the tilting jaw. In principle, however, the sole hold-down device could also be attached to the supporting part in a form-fitting manner, while only the side jaws can be swung out against the force of the release spring.

Während grundsätzlich auch eine Druckfeder als Auslösefeder verwendet werden könnte, wobei eine Kraftrichtungsumkehr durch eine Zugstange erreicht wird, ist es doch bevorzugt, wenn die Auslösefeder eine hinten am Seitenauslösemechanismus und vorn am Bindungsgehäuse befestigte Zugfeder ist.While in principle a compression spring could also be used as a release spring, with a direction of force being reversed by means of a pull rod, it is preferred if the release spring is a tension spring attached at the rear to the side release mechanism and at the front to the binding housing.

Im Falle der Verwendung einer dickeren Skisohle würde bei der erfindungsgemäßen Sicherheitsskibindung die Auslösefeder etwas stärker gespannt werden, was zu einer Erhöhung der Auslösekraft führen könnte. Um in diesem Fall eine entsprechende Anzeige für die erhöhte Seitenauslösekraft zu liefern, kennzeichnet sich eine weitere Ausführungsform der Erfindung dadurch, daß an diesem Ende der Auslösefeder ein zu einem Anzeigeschieber sich nach vorn über die Querachse hinaus erstreckender Haltearm angebracht ist und daß der Anzeigeschieber sich unter einem mit einer Federvorspannungseinstellskala versehenen Sichtfenster in der Oberseite des Tragteils befindet.If a thicker ski sole were used, the release spring would be tensioned somewhat more in the case of the safety ski binding according to the invention, which could lead to an increase in the release force. In order to provide a corresponding indication of the increased lateral release force in this case, a further embodiment of the invention is characterized in that at this end the release spring is attached to an indicator slide extending forward across the transverse axis and that the indicator slide is below a viewing window provided with a spring preload adjustment scale is located in the top of the supporting part.

Da bei einer Höhenverschwenkung des Tragteils das Tragteil und der Anzeigeschieber um verschiedene Achsen schwenken, ergibt sich beim Hochschwenken des Tragteils eine derartige Relativverschiebung zwischen dem Anzeigeschieber und der Federvorspannungseinstellskala, daß die beim Hochschwenken des Sohlenniederhalters erhöhte Vorspannkraft der Auslösefeder angezeigt wird. Bei Verwendung einer dickeren oder dünneren Skistiefelsohle kann also die Vorspannung der Auslösefeder entsprechend nachgestellt werden. Ein weiterer Erfindungsgedanke ist also darin zu sehen, daß der Anzeigeschieber relativ zur Anzeigeskala nicht nur durch Verstellung der Vorspannung der Auslösefeder von Hand mittels der Einstellschraube verschoben wird, sondern in gleichem Sinne und in gleichem Verhältnis auch bei dem geringfügigem Hochschwenken des Sohlenniederhalters. Der Anzeigeschieber liefert somit in jedem Fall eine für alle praktischen Zwecke ausreichende Anzeige der tatsächlichen Vorspannung der Auslösefeder.Since the support member and the indicator slide pivot about different axes when the support member is pivoted in height, there is such a relative displacement between the indicator slide and the spring preload setting scale when the support member is pivoted up that the pretensioning force of the release spring is displayed when the sole retainer is pivoted up. When using a thicker or thinner ski boot sole, the preload of the release spring can be adjusted accordingly. Another idea of the invention is to be seen in the fact that the indicator slide is shifted relative to the indicator scale not only by adjusting the preload of the trigger spring by hand using the adjusting screw, but also in the same sense and in the same ratio even when the sole hold-down is swung up slightly. The indicator slide thus always provides an adequate indication of the actual preload of the release spring for all practical purposes.

Während die Reibungskompensation bei Rücklagen des Skifahrers mit den vorstehend geschilderten Ausführungsformen einwandfrei funktioniert, ergibt sich bei Vorlagen eine Reibungserhöhung, weil der von oben stets nachgeführte Sohlenniederhalter dann unverändert von oben gegen die Skistiefelsohle drückt, während die Reibungskraft zwischen der Stiefelsohle und der auf dem Ski angeordneten Sohlenplatte zunimmt. Dieser Einfluß kann zwar durch eine Sohlenplatte mit geringem Reibungskoeffizienten stark herabgemindert werden; bevorzugt ist es jedoch, wenn keine besondere, reibunn-Dindernde Ausbildung der Sohlenplatte erforder.: ist, indem im Ballenbereich des Skistiefeis eine vertikal bewegliche Trittplatte auf der Skioberseite angeordnet ist, welche über ein Kraftumlenkgetriebe an einen unterhalb der Skisohle und der Bindung verlaufenden Längsschieber derart angeschlossen ist, daß bei Ausübung einer Trittkraft von oben auf die Trittplatte auf den Schieber eine nach hinten gerichtete Kraft ausgeübt wird, und indem das von der Trittplatte abgewandte Ende des Schiebers mittels eines Anschlages einen Gegenanschlag des Tragteils derart hintergreift, daß beim Ausüben der Trittkraft auf die Trittplatte auf das Tragteil ein Schwenkmoment übertragen wird, welches den Sohlenniederhalter nach oben zu bewegen sucht, wobei jedoch die auf das Tragteil über das Kraftumlenkgetriebe ausgeübte Hochschwenkkraft so begrenzt ist, daß sie kleiner bleibt als die von der Auslösefeder ausgeübte Niederhaltekraft. Aufgrund dieser Ausbildung wird mit zunehmender Trittkraft auf die Sohlenplatte die Kraft, mit der der Sohlenniederhalter von oben auf die Skistiefelsohle drückt, zunehmend erniedrigt, so daß der zunehmenden Reibungskraft zwischen Skistiefelsohle und Sohlenplatte eine entsprechend abnehmende Reibungskraft zwischen dem Sohlenniederhalter und der Skistiefelsohlenoberseite gegenübersteht.While the friction compensation for skiers' reserves works perfectly with the above-described embodiments, there is an increase in friction with templates because the sole hold-down, which is always tracked from above, then presses unchanged against the ski boot sole from above, while the frictional force between the sole of the boot and that arranged on the ski Sole plate increases. This influence can be greatly reduced by a sole plate with a low coefficient of friction; it is preferred, however, if no special, friction-preventing design of the sole plate is required: by arranging a vertically movable tread plate on the top of the ski in the ball area of the ski deep ice, which, via a power deflection gear, is connected to a longitudinal slide that runs underneath the ski sole and the binding is connected that when a pedal force is exerted on the tread plate from above, a rearward force is exerted, and in that the end of the pusher facing away from the tread plate engages behind a counter-stop of the supporting part by means of a stop such that when the pedal force is exerted the tread plate is transferred a pivoting moment on the supporting part, which attempts to move the sole hold-down device upwards, however the upward pivoting force exerted on the supporting part via the force-deflecting gear is so limited that it remains smaller than the holding-down force exerted by the release spring. Because of this design, the force with which the sole hold-down presses onto the ski boot sole from above is increasingly reduced with increasing treading force on the sole plate, so that the increasing frictional force between the ski boot sole and the sole plate is offset by a correspondingly decreasing frictional force between the sole hold-down device and the upper side of the ski boot.

Besonders zweckmäßig ist es, wenn die durch die Trittkraft auf das Tragteil ausgeübte Hochschwenkkraft durch geeignete Ausbildung des Kraftumlenkgetriebes maximal annähernd gleich der von der Auslösefeder erzeugten Niederhaltekraft ist. Auf diese Weise kann erreicht werden, daß sowohl bei extremer Rücklage als auch bei extremer Vorlage des Skifahrers die Reibungskräfte zwischen der Skistiefelsohle und der Sohlenplatte bzw. dem Sohlenniederhalter weitgehend gleich sind. Da die Reibungskräfte bei einer normalen Position des Skifahrers auf dem Ski, wo die Skisohle praktisch zwischen Sohlenniederhalter und Sohlenplatte eingespannt ist, höher sind und der Seitenauslösemechanismus unter Berücksichtigung dieser Reibungskräfte eingestellt wird, ist die Seitenauslösung sowohl bei extremer Vorlage als auch bei extremer Rücklage des Skifahrers in erwünschter Weise erleichtert.It is particularly expedient if the swiveling force exerted on the supporting part by the pedal force is at most approximately the same as the hold-down force generated by the release spring by a suitable design of the power deflection gear. In this way it can be achieved that the frictional forces between the ski boot sole and the sole plate or the sole hold-down device are largely the same both with extreme reserve and with extreme presentation of the skier. Since the frictional forces are higher in a normal position of the skier on the ski, where the ski sole is practically clamped between the sole hold-down device and the soleplate, and the side release mechanism is set taking these frictional forces into account, the side release is both with extreme presentation and with extreme resetting of the skier relieved in the desired manner.

Die Erfindung wird im folgenden beispielsweise anhand der Zeichnung beschrieben; in dieser zeigt:

  • Fig. 1 eine teilweise geschnittene Seitenansicht einer erfindungsgemäßen Sicherheitsskibindung für die Halterung einer Skistiefelspitze und
  • Fig. 2 eine Draufsicht der Sicherheitsskibindung nach Fig. 1.
The invention is described below, for example with reference to the drawing; in this shows:
  • Fig. 1 is a partially sectioned side view of a safety ski binding according to the invention for holding a ski boot tip and
  • FIG. 2 shows a top view of the safety ski binding according to FIG. 1.

Nach den Fig. 1 und 2 ist ein Bindungsgrundkörper 38 mittels durch vier Schraublöcher 39 sich hindurcherstreckender Befestigungsschrauben an einem Ski 40 befestigt. Im vorderen Bereich befindet sich am Bindungsgrundkörper 38 das Bindungsgehäuse 12, welches erfindungsgemäß in der Draufsicht U-förmig ausgeschnitten ist, um Platz für ein dort eingesetztes im wesentliches quaderförmiges Tragteil 18 zu schaffen, welches um eine im vorderen Bereich des Bindungsgehäuses 12 oben vorgesehene Querachse 17 schwenkbar am Bindungsgehäuse 12 angebracht ist.1 and 2, a binding base body 38 is fastened to a ski 40 by means of fastening screws extending through four screw holes 39. Located in the front area on the binding base body 38 is the binding housing 12, which according to the invention is cut out in a U-shape in plan view in order to make room for an essentially cuboidal supporting part 18 which is used there and which extends around a transverse axis 17 provided at the top in the front area of the binding housing 12 is pivotally attached to the binding housing 12.

Gemäß Fig. 2 weist das Tragteil 18 im hinteren Bereich zu beiden Seiten der Mittellängsachse 41 der Bindung vertikal verlaufende abgerundete Kippkanten 26 auf, welche mit komplementär dazu ausgebildeten nutenartig vertieften Kippflächen 27 eines Kippbackens 28 zusammenwirken, der in der Mitte auf der der gestrichelt angedeuteten Skistiefelsohle 42 in den Sohlenniederhalter 15 und seitlich davon die schräg nach außen vorstehenden Seitenbacken 13, 14 trägt.2, the support part 18 has in the rear area on both sides of the central longitudinal axis 41 of the binding vertically extending rounded tipping edges 26 which cooperate with complementarily formed recessed tilting surfaces 27 of a tilting jaw 28, which in the middle on the ski boot sole indicated by the dashed lines 42 in the sole hold-down device 15 and laterally from it carries the diagonally outwardly projecting side jaws 13, 14.

An einem den Kippbacken in der Mitte vertikal durchsetzenden Haltebolzen 43 ist das vordere Befestigungsende 22 einer sich im wesentlichen in Längsrichtung erstreckenden Auslösefeder 11 befestigt, welche in Richtung von der Skistiefelsohle 42 weg in der aus Fig. 1 ersichtlichen Weise leicht nach unten abfällt, derart, daß der Winkel a der Wirkungslinie 19 der Auslösefeder 11 relativ zur Horizontalen etwa 5 0 beträgt. Das vordere Ende der Auslösefeder ist an einem als Mutter ausgebildeten Widerlager 44 befestigt. In die Mutter 44 ist ein Widerlagerbolzen 20 eingeschraubt, der mit allseitigem Spiel 23 eine Bohrung in der Vorderwand des Bindungsgehäuses 12 durchsetzt und in einen Widerlagerbolzenkopf 21 mündet, welcher mit seiner teilkugelförmig ausgebildeten Rückseite in einer dazu komplementär ausgebildeten Teilkugellagerfläche 45 derart gelagert ist, daß die von der Auslösefeder 11 ausgeübten Zugkräfte auf das Bindungsgehäuse 12 übertragen werden.The front fastening end 22 of a release spring 11 which extends essentially in the longitudinal direction is fastened to a holding bolt 43 which penetrates the tilting jaw vertically in the middle and which slopes slightly downwards in the direction away from the ski boot sole 42 in the manner shown in FIG. 1, that the angle a of the line of action 19 of the trigger spring 11 is about 5 0 relative to the horizontal. The front end of the release spring is attached to an abutment 44 designed as a nut. In the nut 44, an abutment bolt 20 is screwed, which passes through a hole in the front wall of the binding housing 12 with all-round play 23 and opens into an abutment bolt head 21, which is supported with its partially spherical rear side in a complementarily designed partial ball bearing surface 45 such that the tensile forces exerted by the release spring 11 are transmitted to the binding housing 12.

Durch das Spiel 23, die Teilkugellagerfläche 45 und das seitliche Spiel 23' neben dem Widerlagerbolzenkopf 21 wird eine gewisse Schwenkbewegung des Widerlagerbolzens 20 ermöglicht. Der Widerlagerbolzenkopf 21 ist nach außen hin mit einem Schlitz 46 zum Eingreifen eines Schraubenziehers oder eines Geldstückes versehen. Durch Verdrehen des Widerlagerbolzenkopfes 21 kann die Widerlagermutter 44 in im wesentlichen axialer Richtung verschoben werden, wodurch die Vorspannung der Auslösefeder 11 verändert werden kann.A certain pivoting movement of the abutment pin 20 is made possible by the play 23, the partial ball bearing surface 45 and the lateral play 23 'next to the abutment pin head 21. The abutment bolt head 21 is provided on the outside with a slot 46 for engaging a screwdriver or a coin. By turning the abutment bolt head 21, the abutment nut 44 can be displaced in an essentially axial direction, as a result of which the pretensioning of the release spring 11 can be changed.

Um eine freie Beweglichkeit der Auslösefeder 11 und der mit ihr verbundenen Bauteile beim Hochschwenken des Tragteils 18 zu ermöglichen, sind nicht nur die Spielräume 23, 23', sondern auch die in Fig. 1 weiter gezeigten Spielräume 24, 25 zweckmäßig. In order to enable free movement of the release spring 11 and the components connected to it when the support part 18 is swung up, not only the clearances 23, 23 ', but also the clearances 24, 25 shown in FIG. 1 are expedient .

Am oberen Rand der Widerlagermutter 44 ist noch unterhalb der Querachse 17 ein Haltearm 30 befestigt, welcher sich unter der Querache 17 hindurch nach hinten erstreckt und an seinem Ende einen Anzeigeschieber 29 trägt, der unterhalb eines Sichtfensters 32 liegt, welches hinter der Querachse 17 in der Oberwand des Tragteils 18 angebracht ist. An der Unterseite des Sichtfensters 32 befindet sich eine Federvorspannungseinstellskala 31.At the upper edge of the abutment nut 44, a holding arm 30 is attached below the transverse axis 17, which extends under the transverse axis 17 to the rear and carries at its end a display slide 29, which is below a viewing window 32, which is behind the transverse axis 17 in the Upper wall of the support member 18 is attached. A spring preload adjustment scale 31 is located on the underside of the viewing window 32.

Unterhalb des Ballenbereichs der Skistiefelsohle 42 ist eine sich im wesentlichen quer über den Ski 40 erstreckende Tritt- oder Sohlenplatte 33 angeordnet, die durch eine Drehlagerung 47 unterhalb des Sohlenniederhalters 15 vertikal in geringem Ausmaß beweglich ist. Über ein durch miteinander zusammenwirkende Schrägflächen an der Unterseite der Trittplatte 33 und eines Schiebers 35 gebildetes Kraftumlenkgetriebe 34 wird eine von oben auf die Trittplatte 33 wirkende Trittkraft K in einem gewünschten Verhältnis auf einen unterhalb der Trittplatte 33 im Bindungskörper 38 in Skilängsrichtung verschiebbar gelagerten Schieber 35 derart übertragen, daß diese Kraft den Schieber 35 nach hinten zu verschieben sucht.Arranged underneath the ball area of the ski boot sole 42 is a tread plate or sole plate 33 which extends essentially transversely over the ski 40 and can be moved vertically to a small extent by a rotary bearing 47 below the sole holder 15. Via a force deflection gear 34 formed by interacting inclined surfaces on the underside of the step plate 33 and a slide 35, a step force K acting from above on the step plate 33 is applied in a desired ratio to a slide 35 which is slidably mounted in the binding body 38 below the step plate 33 in the longitudinal direction of the ski transmit that this force tries to move the slide 35 backwards.

Das vordere Ende des Schiebers 35 erstreckt sich bis etwa unter die Querachse 17, wo ein geringfügig nach oben vorspringender Anschlag 36 angebracht ist, der einen Gegenanschlag 37 im unteren Bereich des Tragteils 18 derart von vorn hintergreift, daß eine auf den Schieber 35 nach hinten wirkende Kraft auf das Tragteil 18 ein Drehmoment um die Querachse 17 überträgt, welches den Sohlenniederhalter 15 anzuheben sucht.The front end of the slide 35 extends to about below the transverse axis 17, where a slightly upwardly projecting stop 36 is attached, which engages behind a counter-stop 37 in the lower region of the support part 18 from the front in such a way that one acting on the slide 35 to the rear Force to the support member 18 transmits a torque about the transverse axis 17, which tries to raise the sole hold-down 15.

Aufgrund der erfindungsgemäßen Ausbildung werden bei einer Hochschwenkbewegung des Tragteils 18 der Kippbacken 28 mit dem an ihm angeordneten Bauteilen und der Befestigungsstift 43 einschließlich des Angriffspunktes 16 für das Befestigungsende 22 der Auslesefeder 11 mit geschwenkt. Die Feder 11 kann eine derartige Schwenkbewegung jedoch nur teilweise mitmachen, weil ihr vorderes Ende am Bindungsgehäuse 12 festgelegt ist. Beim Hochschwenken des Tragteils 18 ändert sich also die Relativlage der Auslösefeder 11 zum Tragteil 18 und zum Bindungsgehäuse 12.Due to the design according to the invention, the tilting jaws 28 with the components arranged on them and the fastening pin 43 including the point of engagement 16 for the fastening end 22 of the readout spring 11 are also pivoted during a pivoting movement of the support part 18. However, the spring 11 can only partially participate in such a pivoting movement because its front end is fixed to the binding housing 12. When the support part 18 is pivoted up, the relative position of the release spring 11 to the support part 18 and to the binding housing 12 changes.

Die Wirkungsweise der beschriebenen Sicherheitsskibindung ist wie folgt:The operation of the described safety ski binding is as follows:

Die Grundeinstellung der Bindung relativ zur Dicke der Skistiefelsohle 42 ist derart, daß die in die Bindung eingesetzte Skistiefelsohle zwischen der Sohlenplatte 33 und dem Sohlenniederhalter 15 in vertikaler Richtung so eingeklemmt wird, daß beispielsweise von oben und unten eine Kraft von 200 N auf die Schuhsohle einwirkt.The basic setting of the binding relative to the thickness of the ski boot sole 42 is such that the ski boot sole inserted into the binding is clamped in the vertical direction between the sole plate 33 and the sole hold-down device 15 such that, for example, a force of 200 N acts on the shoe sole from above and below .

Gerät der Skifahrer in Rücklage, so wird der Sohlenniederhalter 15 von unten zunehmend belastet und die Sohlenplatte 33 zunehmend entlastet. Die Reibkraft zwischen Skistiefelsohle 42 und Sohlenplatte 33 nimmt dabei ab, während die Reibkraft zwischen dem Sohlenniederhalter 15 und der Oberseite der Skistiefelsohle 42 annähernd gleich bleibt bzw. etwas zunimmt. Die Seitenauslösung wird entsprechend erleichtert.If the skier is in reserve, the sole hold-down device 15 is increasingly loaded from below and the sole plate 33 is increasingly relieved. The frictional force between the ski boot sole 42 and the sole plate 33 decreases, while the frictional force between the sole hold-down device 15 and the upper side of the ski boot sole 42 remains approximately the same or increases somewhat. The page release is correspondingly facilitated.

Gerät der Skifahrer in eine Vorlage, so erhöht sich die nach unten auf die Trittplatte ausgeübte Trittkraft K auf Werte über 200 N. Der die Normalkraft von 200 N übersteigende Kraftanteil entlastet den nach unten gedrückten Sohlenniederhalter 15 zunehmend, wirkt also der niederhaltenden Kraft der Auslösefeder 11 entgegen. Bei maximaler Trittkraft K soll das vom Schieber 35 auf das Tragteil 18 ausgeübte entlastende Drehmoment aber gerade noch nicht größer als das von der Auslösefeder 11 ausgeübte niederhaltende Moment sein, so daß schließlich bei maximaler Trittkraft K die Oberseite der Skistiefelsohle 42 gerade von der niederhaltenden Kraft des Sohlenniederhalters 15 annähernd entlastet ist. Die Reibungszunahme zwischen Skistiefelsohle 42 und der Trittplatte 33 wird also durch eine Reibungsabnahme zwischen Sohlenniederhalter 15 und Skistiefelsohle 42 zumindest kompensiert.If the skier gets into a template, the pedaling force K exerted downwards on the tread plate increases to values above 200 N. The force component exceeding the normal force of 200 N increasingly relieves the pressure on the sole hold-down device 15, thus acting on the holding force of the release spring 11 opposite. At maximum pedaling force K, the relieving torque exerted by the slider 35 on the supporting part 18 should just not be greater than the holding moment exerted by the release spring 11, so that finally, at maximum pedaling force K, the top of the ski boot sole 42 is just affected by the holding force of the Sole retainer 15 is approximately relieved. The increase in friction between the ski boot sole 42 and the tread plate 33 is thus at least compensated for by a decrease in friction between the sole hold-down device 15 and the ski boot sole 42.

Wichtig ist weiter, daß beim Hochschwenken des Sohlenniederhalters 15 und damit des Tragteils 18 eine Relativverschiebung zwischen dem Anzeigeschieber 29 und der Einstellskala 31 in dem Sinne erfolgt, daß die durch das Hochschwenken des Sohlenniederhalters 15 erhöhte Vorspannkraft der Auslösefeder 11 im Sichtfenster 32 auf der Einstellskala 31 zur Anzeige gebracht wird. Sollte also ein Stiefel mit einer dickeren Skistiefelsohle 42 in die Bindung eingestellt werden, so kommt die hierdurch bewirkte erhöhte Vorspannung der Auslösefeder 11 zur Anzeige und kann durch Verdrehen des Widerlagerbolzens 20 in erwünschter Weise nachgestellt werden. Wesentlich ist, daß die Wirkungslinie 19 der Auslösefeder 11 einen Abstand A von der Querachse 17 hat, wodurch ein Hebelarm gebildet wird, der es der Auslösefeder 11 ermöglicht, ein den Sohlenniederhalter 15 niederhaltendes Drehmoment auf das Tragteil 18 auszuüben. Durch geeignete Wahl der Größe des Abstandes A kann dieses Drehmoment auf einen gewünschten Wert eingestellt werden.It is also important that when swiveling the Sole retainer 15 and thus the support member 18 a relative displacement between the slide 29 and the adjustment scale 31 takes place in the sense that the increased biasing force of the release spring 11 in the viewing window 32 on the adjustment scale 31 is displayed by pivoting the sole retainer 15. So if a boot with a thicker ski boot sole 42 is inserted into the binding, the resulting increased preload of the release spring 11 is displayed and can be adjusted as desired by turning the abutment bolt 20. It is essential that the line of action 19 of the release spring 11 is at a distance A from the transverse axis 17, whereby a lever arm is formed which enables the release spring 11 to exert a torque holding down the sole hold-down device 15 on the supporting part 18. By a suitable choice of the size of the distance A, this torque can be set to a desired value.
