Abstract

A laterally releasable toe unit of a safety ski binding has a sole clamp (18) which is pivotable about substantially vertical tilting axes (16) provided on the binding housing (11) and is pressed by a release spring (12) against tilting surfaces defining the tilting axes (16). The angle alpha between the line of action (19) of the release spring (12) and the tilting axis (16) is smaller than 90 DEG , so that a force N is exerted on the sole clamp (18) by the release spring which draws it downwardly.

Description

Die Erfindung betrifft einen seitenauslösbaren Backen, insbesondere Vorderbacken, einer Sicherheitsskibindung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a side-releasable cheek, in particular a toe, a safety ski binding according to the preamble of patent claim 1.

Es ist bereits ein Auslösevorderbacken für Skibindungen bekannt (AT-A- 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-A-300 630), in which a sole hold-down device is arranged on a laterally releasable front jaw, which can deflect resiliently 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-A- 32 30 186), 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-A-32 30 186) 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 this requires 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 release 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.

Nach einem älteren Vorschlag (DE-A- 36 05 313) ist vorgesehen, daß der Sohlenniederhalter, die Seitenbacken, der Seitenauslösemechanismus und der Angriffspunkt der Auslösefeder am Seitenauslösemechanismus an einem relativ zum Bindungsgehäuse um eine 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. Hierdurch wird von der Auslösefeder ein Drehmoment um die Querachse erzeugt, welche den Sohlenniederhalter nach unten zu bewegen sucht. Aufgrund dieser Ausbildung werden nicht nur die mit einer Schneezwischenlage zwischen Schuhsohle und Ski bedingten Nachteile, nämlich insbesondere eine Verklemmung der Schuhsohle vermieden, sondern es wird auch bereits eine begrenzte Reibungskompensation erzielt. Gerät der Skifahrer nämlich in Rücklage, so wird zwar die Reibung am Sohlenniederhalter etwas erhöht, gleichzeitig nimmt aber die Reibung an der Sohlenplatte stark ab, so daß die Seitenauslösung nicht erschwert, sondern eher erleichtert ist, was im Falle eines Rückwärtssturzes durchaus erwünscht ist. Ein Nachteil dieser vorbekannten Sicherheitsskibindung besteht darin, daß ein um eine Querachse hochschwenkbares Gehäuse vorgesehen sein muß, was einen erhöhten Herstellungsaufwand mit sich bringt.According to an older proposal (DE-A-36 05 313) it is provided that the sole hold-down device, the side jaws, the side release mechanism and the point of application of the release spring on the side release mechanism are arranged on a support part which can be swiveled up about a transverse axis relative to the binding housing and that the transverse axis is in itself such a distance above the line of action of the trigger spring that from the top one of the trigger spring originating, predetermined, resilient hold-down force acts on the ski boot sole. As a result, the trigger spring generates a torque about the transverse axis, which attempts to move the sole hold-down device downwards. Due to this design, not only the disadvantages caused by a snow liner between the shoe sole and the ski, namely in particular jamming of the shoe sole, are avoided, but also a limited friction compensation is already achieved. If the skier gets into the reserve, the friction on the sole hold-down device is increased somewhat, but at the same time the friction on the sole plate decreases significantly, so that side release is not difficult, but rather easier, which is definitely desirable in the event of a backward fall. A disadvantage of this known safety ski binding is that a housing which can be swiveled up about a transverse axis must be provided, which entails an increased production outlay.

Das Ziel der Erfindung besteht darin, einen seitenauslösbaren Backen mit einem um Kippachsen seitlich ausschwenkbaren Sohlenhalter, wie er beispielsweise aus der DE-PS 31 29 536 bekannt ist, so weiterzubilden, daß bei kaum erhöhtem baulichen Aufwand selbsttätig ein zu festes Einklemmen der Skistiefelsohle zwischen dem Niederhalter des Sohlenhalters und der Skioberfläche bzw. einer darauf angeordneten Trittplatte vermieden wird und bei Rücklage des Skifahrers eine gewisse Erleichterung des seitlichen Auslösevorgangs erzielt wird.The aim of the invention is to develop a side-releasable jaw with a sole holder which can be swiveled out laterally about tilting axes, as is known, for example, from DE-PS 31 29 536, in such a way that, with little increased construction effort, the ski boot sole is clamped too tightly between them Hold-down of the sole holder and the ski surface or a step plate arranged thereon is avoided and a certain relief of the lateral release process is achieved when the skier is lying back.

Zur Lösung dieser Aufgabe sind die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 vorgesehen.To achieve this object, the features of the characterizing part of claim 1 are provided.

Der Grundgedanke der Erfindung besteht also darin, die bereits für die Seitenauslösung erforderlichen Kippflächen bzw. Kippkanten zusätzlich als Auf- bzw. Ab-Gleitflächen für den Sohlenhalter auszunutzen, wozu lediglich ein gewisser Verschiebefreiraum für den Sohlenhalter sowie für die an ihm angreifenden Auslösekraft-Übertragungselemente und der im Patentanspruch 1 definierte Winkel zwischen den Kippachsen und der Wirkungslinie der Auslösefeder vorgesehen werden muß. Beim Einführen einer etwas dickeren Stiefelsohle wird der Sohlenhalter entlang der Kippachsen etwas nach oben geschoben, während beim anschließenden Einsetzen einer dünneren Schuhsohle die nach unten wirkende Kraftkomponente der Auslösefeder den Sohlenhalter entlang der Kippachsen nach unten soweit verschiebt, bis der Niederhalter von oben gegen die Sohle des Skistiefels leicht angedrückt ist. Die Skistiefelsohle wird somit zangenartig zwischen der Trittplatte auf der Skioberfläche und dem Niederhalter des Sohlenhalters eingespannt, wobei die vertikale Spannkraft von der Auslösefeder mitgeliefert wird. Wesentlich ist, daß vor der Trittplatte unter dem Niederhalter des Sohlenhalters ein solcher Freiraum vorliegt, daß jede vorkommende Skistiefelsohle schräg von oben unter den Niederhalter eingeführt werden kann.The basic idea of the invention is therefore to additionally utilize the tilting surfaces or tilting edges already required for the side release as up and down sliding surfaces for the sole holder, for which purpose only a certain one Freedom of movement for the sole holder and for the triggering force transmission elements acting on it and the angle defined in claim 1 between the tilt axes and the line of action of the trigger spring must be provided. When a slightly thicker boot sole is inserted, the sole holder is pushed up a little along the tilt axes, while when a thinner shoe sole is subsequently inserted, the downward force component of the release spring pushes the sole holder down along the tilt axis until the hold-down device pushes against the sole of the Ski boot is lightly pressed. The ski boot sole is thus clamped between the tread plate on the ski surface and the hold-down device of the sole holder, the vertical tension force being supplied by the release spring. It is essential that there is such a free space in front of the tread plate under the hold-down of the sole holder that any ski boot sole can be inserted obliquely from above under the hold-down.

Kommt der Skifahrer bei Verwendung des erfindungsgemäßen Backens als Vorderbacken in eine Rücklage, so kann die Schuhsohle den Sohlenhalter entlang der Kippachsen etwas nach oben verschieben. Die Schuhsohle hebt dabei von der Skioberfläche bzw. der Trittplatte ab, so daß die dort sonst vorhandene seitliche Reibung entfällt und der seitliche Auslösevorgang in erwünschter Weise erleichtert wird.If the skier comes into a reserve when using the cheek according to the invention as a toe, the sole of the shoe can shift the sole holder somewhat upwards along the tilting axes. The sole of the shoe lifts off the ski surface or the tread plate, so that the lateral friction otherwise present there is eliminated and the lateral release process is facilitated in the desired manner.

Praktisch realisiert werden kann der Winkel zwischen der Auslösefeder-Wirkungslinie und den Kippachsen durch die Maßnahmen der Ansprüche 2 oder 3, wobei zur Vermeidung einer zu starken Schrägstellung der Wirkungslinie der Auslösefeder und der Kippachsen zweckmäßigerweise beide Maßnahmen so kombiniert werden, daß sie etwa in gleichem Maße zu dem gewünschten Effekt beitragen.The angle between the release spring line of action and the tilt axes can be practically implemented by the measures of claims 2 or 3, whereby in order to avoid an excessive inclination of the line of action of the release spring and the tilt axes, both measures are expediently combined in such a way that they are approximately to the same extent contribute to the desired effect.

Eine besonders zweckmäßige Dimensionierung des vorerwähnten Winkels ist durch den Patentanspruch 4 definiert.A particularly expedient dimensioning of the aforementioned angle is defined by claim 4.

Von besonderem Vorteil sind die im Anspruch 5 definierten Maßnahmen, denn hierdurch wird ein besonders kompakter Aufbau erzielt. Weitere zweckmäßige Weiterbildungen der Erfindung sind durch die Ansprüche 6 und 7 gekennzeichnet.The measures defined in claim 5 are of particular advantage, since this results in a particularly compact structure. Further expedient developments of the invention are characterized by claims 6 and 7.

Die erfindungsgemäße Ausbildung des Anzeigefortsatzes nach Anspruch 7 hat dabei den besonderen Vorteil, daß beim Einstellen einer etwas dickeren Schuhsohle in den Backen, was eine stärkere Vorspannung der Auslösefeder zur Folge hat, gleichzeitig auch der Anzeigefortsatz mitverschoben wird, so daß die durch das Einstellen der dickeren Schuhsohle bedingte größere Auslösehärte zur Anzeige gebracht wird. Durch Verstellung der Vorspannung der Auslösefeder kann also wieder der gewünschte Auslösewert eingestellt werden.The inventive design of the display extension according to claim 7 has the particular advantage that when setting a somewhat thicker shoe sole in the cheeks, which results in a stronger preload of the release spring, the display extension is also shifted, so that by adjusting the thicker The sole of the shoe is caused by greater trigger hardness. By adjusting the preload of the release spring, the desired release value can be set again.

Eine Verstellbarkeit der Vorspannung der Auslösefeder wird auf einfache Weise durch die Merkmale des Anspruches 8 verwirklicht.An adjustability of the bias of the trigger spring is realized in a simple manner by the features of claim 8.

Besonders vorteilhaft ist es, wenn die Auslösefeder gemäß den Merkmalen des Patentanpruchs 9 am Sohlenhalter angreift. Bevorzugt ist die Schwenkwelle relativ zum Sohlenhalter verdrehbar, wodurch auf einfache Weise eine Relativverdrehung zwischen dem am Sohlenhalter angreifenden Federende und dem Sohlenhalter ermöglicht wird.It is particularly advantageous if the release spring acts on the sole holder according to the features of patent claim 9. Preferably, the pivot shaft can be rotated relative to the sole holder, which in a simple manner enables relative rotation between the spring end engaging the sole holder and the sole holder.

Um bei dieser Ausführungsform ein möglichst senkrechtes Angreifen der Kraft der Auslösefeder am Sohlenhalter zu ermöglichen, ist die Maßnahme nach Anspruch 10 vorgesehen.In order to enable the force of the release spring on the sole holder to be applied as vertically as possible in this embodiment, the measure according to claim 10 is provided.

Besonders vorteilhaft ist es, wenn der Sohlenhalter gemäß Anspruch 11 zweigeteilt ausgebildet ist. Diese Maßnahme ist durch die DE-C- 31 29 536 an sich bekannt. Aus der vorgenannten Patentschrift ist auch die Abstützung des Skischuhs gemäß Anspruch 19 grundsätzlich bekannt. Im Zusammenhang mit der vorliegenden Erfindung hat diese Abstützung aber den Vorteil, daß die erhöhte Vorspannung der Auslösefeder durch Einspannung eines Skischuhs mit breiterer Sohle vom Anzeigefortsatz automatisch zur Anzeige gebracht wird, so daß auch in diesem Fall eine Korrektur der Einstellung der Auslösehärte problemlos möglich ist.It when the sole holder is formed in two parts according to claim 11 is particularly advantageous. This measure is known per se from DE-C-31 29 536. From the aforementioned Patent specification, the support of the ski boot according to claim 19 is also known in principle. In connection with the present invention, this support has the advantage, however, that the increased preload of the release spring is automatically indicated by the display extension by clamping a ski boot with a wider sole, so that a correction of the setting of the release hardness is also possible in this case without any problems.

Eine besonders vorteilhafte Weiterbildung der Erfindung ist durch den Patentanspruch 12 gekennzeichnet. Auf eine baulich äußerst einfache Weise wird so zusätzlich zu der Seitenauslösung auch noch eine Höhenauslösung des Backens gewährleistet. Die einzigen baulichen Maßnahmen hierfür bestehen in der geeigneten Anordnung des Höhenkippanschlages sowie der Höhenkippgegenflächen und der dazwischenliegenden Freiräume.A particularly advantageous development of the invention is characterized by claim 12. In a structurally extremely simple way, a height release of the jaw is also guaranteed in addition to the side release. The only structural measures for this consist in the suitable arrangement of the height-tilt stop as well as the height-tilt counter surfaces and the free spaces in between.

Durch die Maßnahmen der Ansprüche 13 oder 14 können auch noch unterschiedliche Auslösehärten bei einer Höhenauslösung erzielt werden. Sofern die Höhenkippgegenfläche etwas näher an dem Höhenkippanschlag liegt, wird eine größere Höhenauslösehärte erzielt, was z.B. für die Verwendung der Sicherheitsskibindung durch einen Rennläufer von Vorteil sein kann.By means of the measures of claims 13 or 14, different release hardnesses can also be achieved with a height release. If the countertop surface is slightly closer to the end stop, a higher level of hardness is achieved, which is e.g. can be advantageous for a racer to use the safety ski binding.

In jedem Fall sollte bei dem erfindungsgemäßen Backen eine Trittplatte gemäß Anspruch 15 vorgesehen sein.In any case, a tread plate according to claim 15 should be provided in the baking according to the invention.

Wird eine solche Trittplatte gemäß Patentanspruch 16 weitergebildet, so kann auch bei einer Vorlage des Skifahrers, die mit einem erhöhten Druck von oben auf die Trittplatte verbunden ist, eine Reibungskompensation dadurch erzielt werden, daß der Niederhalter des Sohlenhalters dann von der Oberseite der Sohle abgehoben wird, wodurch die dort sonst vorhandene Reibung bei einer Seitenauslösung zum Verschwinden gebracht wird. Wirksam ist jetzt nur noch die Reibung zwischen der Skistiefelsohle und der Trittplatte. Wesentlich ist, daß die Reibungskompensation nicht durch eine teilweise Kompensation der Auslösekraft, sondern vielmehr lediglich durch ein Hochschieben des Sohlenhalters an den Kippflächen erzielt wird.If such a tread plate is developed according to claim 16, friction compensation can also be achieved when the skier is presented with an increased pressure from above on the tread plate in that the hold-down device of the sole holder is then lifted off the top of the sole , whereby the friction that is otherwise present there is made to disappear when the side is triggered. Now only the friction between the ski boot sole and the tread plate is effective. Essential is that the friction compensation is not achieved by partial compensation of the release force, but rather only by pushing the sole holder up on the tilting surfaces.

Eine weitere Ausführungsform der Trittplatte ist durch die Patentansprüche 18 und 19 gekennzeichnet. Diese Ausführungsform ist auch unabhängig von dem erfindungsgemäßen Backen anwendbar, sollte aber nur bei solchen seitenauslösbaren Backen angewendet werden, bei denen nach dem Ausschöpfen des seitlichen Verschiebebereichs der Trittplatte die auf den Backen wirkende Rückstellkraft bereits soweit abgesunken ist, daß die Summe aus der verbleibenden Rückstellkraft und der Reibkraft deutlich geringer als der Aulösewert ist.Another embodiment of the tread plate is characterized by claims 18 and 19. This embodiment can also be used independently of the jaws according to the invention, but should only be used in the case of side-releasable jaws in which, after the lateral displacement area of the tread plate has been exhausted, the restoring force acting on the jaws has already dropped to such an extent that the sum of the remaining restoring force and the friction force is significantly less than the Aösöswert.

Die so ausgebildete Trittplatte bietet für den Skifahrer eine dreifache Sicherheit. Zum einen gewährleistet der vorzugsweise aus Teflon bestehende reibungsarme Belag eine Sicherheit für den Fall, daß die seitliche Verschiebbarkeit der Trittplatte durch Festfrieren oder Korrosion entfallen sollte. Dann verbleibt noch die vergleichsweise geringe Reibung zwischen dem reibungsarmen Belag und der Schuhsohle.The step plate designed in this way offers triple security for the skier. On the one hand, the low-friction covering, which is preferably made of Teflon, ensures security in the event that the sideways displacement of the tread plate due to freezing or corrosion should be eliminated. Then there is the comparatively low friction between the low-friction covering and the shoe sole.

Sollte die verschiebbare Trittplatte aus ihrer Halterung herausfallen und verlorengehen, dann bietet die Nottrittfläche noch die erforderliche reibungsarme Abstützung. Von besonderer Bedeutung ist, daß die Nottrittfläche nicht aus einem sehr abriebresistenten reibungsarmen Material bestehen muß, weil sie normalerweise nicht benutzt wird und nur beim Verlust der seitlich verschiebbaren Trittplatte für einen relativ kurzen Zeitraum ihre Funktion erfüllen muß.If the sliding tread plate falls out of its holder and is lost, the emergency tread surface still offers the necessary low-friction support. It is of particular importance that the emergency tread surface does not have to be made of a very abrasion-resistant, low-friction material, because it is normally not used and only has to perform its function for a relatively short time if the laterally displaceable tread plate is lost.

Nach Fig. 1 und 2 ist auf der Oberfläche eines Ski 15 ein Bindungsgehäuse 11 mittels Schrauben 40 befestigt, welches auf der vom Skischuh 14 abgewandten Seite eine im wesentlichen in Skilängsrichtung verlaufende annähernd zylindrische Ausnehmung 41 zur Aufnahme einer Auslösefeder 12 aufweist. Die Auslösefeder 12 stützt sich schuhseitig an einem radial nach innen vorspringenden Ring-Widerlager 11′ ab und erstreckt sich von dort schräg nach unten und vorn in ein hohlzylindrisches, schalenartiges Widerlager 24 hinein, welches innerhalb der Ausnehmung 41 kolbenartig axial gleiten kann. Das Widerlager 24 weist einen axialen Anzeigefortsatz 25 auf, dessen dem Skistiefel 14 zugewandtes Ende unterhalb eines mit einer Auslösehärteskala 26 versehenen Fensters 27 in der Oberseite des Bindungsgehäuses 11 angeordnet ist.1 and 2, a binding housing 11 is fastened to the surface of a ski 15 by means of screws 40, which on the side facing away from the ski boot 14 has an approximately cylindrical recess 41 running essentially in the longitudinal direction of the ski for receiving a release spring 12. The trigger spring 12 is supported on the shoe side on a radially inwardly projecting ring abutment 11 'and extends from there obliquely downwards and forwards into a hollow cylindrical, shell-like abutment 24, which can slide axially within the recess 41 like a piston. The abutment 24 has an axial display extension 25, the end of which faces the ski boot 14 is arranged below a window 27 provided with a release hardness scale 26 in the upper side of the binding housing 11.

In eine zentrale Bohrung 42 im vorderen Boden des Widerlagers 24 verläuft eine mit einem z.B. durch einen Schraubenzieher verdrehbaren Kopf 43 versehene Zugstange 23 koaxial mit der Auslösefeder 12. Die Zugstange 23 besteht aus einem mit dem Kopf 43 verbundenen und eine axiale Gewindebohrung aufweisenden Teil 23˝, in welches von der Seite des Skistiefels 14 her ein zweites, als Gewindestange ausgebildetes Teil 23′ eingeschraubt ist. Das Teil 23′ erstreckt sich durch eine Öffnung 44 innerhalb des Widerlagers 11′ mit allseitigem deutlichem Spiel hindurch zu einer leicht nach vorn gekippten, im wesentlichen jedoch vertikalen Schwenkwelle 28, die mittels einer Bohrung 45 im Ende des Teils 23′ umgriffen wird, und zwar im Bereich einer ringförmigen Ausnehmung, die eine konische Schrägfläche 29 aufweist. Der Konuswinkel auf der dem Skistiefel 14 zugewandten Seite der betreffenden Ausnehmung entspricht dem Winkel zwischen der Achse der Zugstange 23, d.h. der Wirkungslinie 19 der Auslösefeder 12 und der Achse der Schwenkwelle 28. Auf diese Weise wirkt die Kraft der Auslösefeder 12 senkrecht auf die Schrägfläche 29.In a central bore 42 in the front bottom of the abutment 24 one with a e.g. by a screwdriver rotatable head 43 provided pull rod 23 coaxially with the release spring 12. The pull rod 23 consists of a part connected to the head 43 and having an axial threaded bore 23 ', in which from the side of the ski boot 14 a second, designed as a threaded rod Part 23 'is screwed in. The part 23 'extends through an opening 44 within the abutment 11' with clear play on all sides to a slightly forward-tilted, but essentially vertical pivot shaft 28, which is encompassed by means of a bore 45 in the end of the part 23 ' in the region of an annular recess which has a conical inclined surface 29. The cone angle on the side of the relevant recess facing the ski boot 14 corresponds to the angle between the axis of the pull rod 23, i.e. the line of action 19 of the release spring 12 and the axis of the pivot shaft 28. In this way, the force of the release spring 12 acts perpendicularly on the inclined surface 29.

Nach den Fig. 1 und 2 sind an der relativ zur Zugstange 23 nicht verdrehbaren Schwenkwelle 28 die beiden Hälften 18′, 18˝ eines Sohlenhalters 18 gelenkig angeordnet. Zu diesem Zweck weisen die beiden Sohlenhalterhälften 18′, 18˝ sich jeweils über die vertikale Mittellängsebene 13 hinaus erstreckende Vorsprünge 30′, 30˝ auf, die in der aus Fig. 1 ersichtlichen Weise vertikal gegeneinander versetzt sind und mit der Schwenkwelle 23 in Dreheingriff stehen. In vertikaler Richtung ist der Sohlenhalter 18 relativ zu der Schwenkwelle 28 fest, also unverschiebbar.1 and 2, the two halves 18 ', 18' of a sole holder 18 are articulated on the pivot shaft 28 which cannot be rotated relative to the pull rod 23. For this purpose, the two sole holder halves 18 ', 18' each extend beyond the vertical central longitudinal plane 13 and protrusions 30 ', 30' which are vertically offset in the manner shown in FIG. 1 and are in rotational engagement with the pivot shaft 23 . In the vertical direction, the sole holder 18 is fixed relative to the pivot shaft 28, that is to say cannot be displaced.

Beidseits der vertikalen Mittellängsebene 13 sind nach den Fig. 1 und 2 an der dem Skistiefel 14 zugewandten Seite des Bindungsgehäuses im wesentlichen aufrecht auf der Skioberfläche stehende Kippachsen 16 definierende Kippflächen 20 vorgesehen, die gleich ausgebildet und symmetrisch zur Mittellängsebene 13 sind. Mit diesen Kippflächen wirken daran durch die Auslösefeder 12 zur Anlage gebrachte komplementäre Kippgegenflächen 17 der beiden Hälften 18′, 18˝ des Sohlenhalters 18 zusammen.On both sides of the vertical central longitudinal plane 13, according to FIGS. 1 and 2, on the side of the binding housing facing the ski boot 14, tilting axes 16 are provided which are essentially upright and which are of the same design and are substantially upright on the ski surface are symmetrical to the central longitudinal plane 13. With these tilting surfaces, complementary tilting counter-surfaces 17 of the two halves 18 ', 18˝ of the sole holder 18 act together through the release spring 12.

Am Sohlenhalter befindet sich ein von oben auf der Sohle 22 des Skistiefels 14 aufliegender Niederhalter 21; außerdem weist der Sohlenhalter zwei seitliche Schenkel auf, an denen seitliche Rollen 46 angeordnet sind, die seitliche Abstützstellen 38 für die Schuhsohle 22 definieren. Die Abstützstellen 38 befinden sich in den Bereichen der Seite der Skistiefelsohle 22, wo die Sohle 22 schräg nach vorn zuläuft.On the sole holder there is a hold-down device 21 resting on the sole 22 of the ski boot 14 from above; In addition, the sole holder has two lateral legs, on which lateral rollers 46 are arranged, which define lateral support points 38 for the shoe sole 22. The support points 38 are located in the areas of the side of the ski boot sole 22 where the sole 22 tapers forward.

Außerdem befinden sich im mittleren Bereich der Sohlenhalter-Hälften 18′, 18˝ vordere Abstützrollen 47, die vordere Abstützstellen 37 für die Sohle 22 des Skistiefels definieren.In addition, in the central region of the sole holder halves 18 ', 18˝ front support rollers 47, which define front support points 37 for the sole 22 of the ski boot.

Der Sohlenhalter 18 ist mit seinen vorderen Bereichen in einem Freiraum 48 des Bindungsgehäuses 11 derart angeordnet, daß er relativ zu den Kippachsen 16 in vertikaler Richtung innerhalb eines solchen Bereiches verschoben werden kann, daß alle vorkommenden unterschiedlichen Stärken der Sohle 22 vom Sohlenhalter 18 eingespannt werden können. Auch die Zugstange 23 weist innerhalb der Öffnung 44 des Widerlagers 11′ einen entsprechenden vertikalen Spielraum auf.Auch muß der Kopf 43 innerhalb des Widerlagers 24 einen entsprechenden Bewegungsspielraum besitzen.The sole holder 18 is arranged with its front areas in a free space 48 of the binding housing 11 such that it can be displaced in relation to the tilting axes 16 in the vertical direction within such a range that all occurring different thicknesses of the sole 22 can be clamped in by the sole holder 18 . The pull rod 23 has a corresponding vertical clearance within the opening 44 of the abutment 11 '. Also the head 43 within the abutment 24 must have a corresponding range of motion.

Oben ist der Freiraum 48 durch einen mit dem Bindungsgehäuse 11 fest verbundenen Höhenkippanschlag 31 abgeschlossen, unterhalb dessen sich eine im wesentlichen horizontale Höhenkippgegenfläche 32 des Sohlenhalters 18 befindet. Über diese Höhenkippgegenfläche 32 kann ein auf der Oberseite des Sohlenhalters 18 angeordneter Schieber 33 geschoben werden, der mit seiner oberen Fläche eine etwas höher gelegene zweite Höhenkippgegenfläche 32′ definiert. Wenn die untere Höhenkippgegenfläche 32 wirksam werden soll, befindet sich der Schieber 33 in der aus Fig. 1 ersichtlichen Lage, in der er von der schuhseitigen Fläche des Sohlenhalters 18 nach außen vorsteht, so daß er von dort in Richtung des Pfeiles in Fig. 1 betätigt werden kann, um dann in die in Fig. 1 gestrichelt dargestellte Position zu gelangen, in welcher die obere Höhenkippgegenfläche 32′ die Funktion der zuvor wirksam Höhenkippgegenfläche 32 übernimmt. Ein oben zwischen dem Höhenkippanschlag 31 und dem Sohlenhalter 18 auf dem Vorderbacken herausragendes Betätigungsglied 49, welches unten mit dem Schieber 33 in Eingriff steht, gestattet es, daß der Skifahrer durch Druck von oben auf das Betätigungsglied 49 den Schieber 33 aus der in Fig. 1 gestrichelten Position wieder in die in Fig. 1 in ausgezogenen Linien dargestellte Position zum Skistiefel 14 hin verschiebt, in welcher die untere Höhenkippgegenfläche 32 mit dem Höhenkippanschlag 31 zusammenwirkt.At the top, the free space 48 is closed off by a height-tilt stop 31, which is firmly connected to the binding housing 11 and below which there is an essentially horizontal counter-height surface 32 of the sole holder 18. A slider 33 arranged on the upper side of the sole holder 18 can be pushed over this counterturning surface 32 which, with its upper surface, has a second one located somewhat higher Height tilt counter surface 32 'defined. If the lower countertop surface 32 is to take effect, the slide 33 is in the position shown in FIG. 1, in which it protrudes outwards from the shoe-side surface of the sole holder 18, so that from there in the direction of the arrow in FIG. 1 can be actuated in order to then reach the position shown in dashed lines in Fig. 1, in which the upper counter tilting surface 32 'takes over the function of the counter tilting surface 32 previously effective. An actuator 49 protruding between the leveling stop 31 and the sole holder 18 on the front jaw, which engages with the slider 33 at the bottom, allows the skier to push the slider 33 from the position shown in FIG Dashed position again in the position shown in Fig. 1 in solid lines to ski boots 14 in which the lower countertop surface 32 cooperates with the height stop 31.

Unterhalb des vorderen Bereiches der Sohle 22 befindet sich eine mit einem reibungsarmen Belag 35 versehene Trittplatte 34, die über unter ihr angeordnete Keilflächen 50, 50′ auf einen in Skilängsrichtung verschiebbaren Keil 36′ einwirkt, der an eine dicht über der Skioberfläche befindliche in Skilängsrichtung verschiebbare Druckstange 36˝ auf einen um eine Querachse 51 verschwenkbaren Winkelhebel 36‴ einwirkt. Der im wesentlichen vertikal nach unten verlaufende Arm des Winkelhebels 36‴ wird von der Druckstange 36˝ in Skilängsrichtung beaufschlagt. Der andere, im wesentlichen horizontal verlaufende Arm des Winkelhebels 36‴ greift von unten an der Schwenkwelle 28 an.Below the front area of the sole 22 there is a step plate 34 provided with a low-friction covering 35, which acts via wedge surfaces 50, 50 'arranged below it on a wedge 36' which is displaceable in the longitudinal direction of the ski and which can be displaced in a longitudinal direction of the ski just above the ski surface Push rod 36˝ acts on a pivotable lever 36 verschw about a transverse axis 51. The substantially vertically downward arm of the angle lever 36 ‴ is acted upon by the push rod 36˝ in the longitudinal direction of the ski. The other, essentially horizontal arm of the angle lever 36 ‴ engages the pivot shaft 28 from below.

Durch Druckausübung auf die Trittplatte 34 in Richtung des Pfeiles f nach unten wird über die Keilflächen 50, 50′ eine Schubkraft nach vorn auf die Druckstange 36˝ ausgeübt, welche den Winkelhebel 36‴ im Uhrzeigersinn schwenkt, so daß der Sohlenhalter 18 entlang der Kippflächen 20 nach oben verschoben wird.By exerting pressure on the tread plate 34 in the direction of the arrow f downward, a thrust force is exerted on the push rod 36 'via the wedge surfaces 50, 50', which swivels the angle lever 36 'clockwise, so that the sole holder 18 along the tilting surfaces 20th is moved upwards.

Die Wirkungsweise des beschriebenen Vorderbackens ist wie folgt:
Aufgrund der Schrägstellung der Wirkungslinie 19 der Auslösefeder 12 sowie der Neigung der Schwenkwelle 28 in der Weise, daß ihr oberes Ende dem Skistiefel 14 näher als bei senkrechter Anordnung auf der Oberfläche des Skis 15 liegt, greift die Zugstange 23 in der aus Fig. 1 ersichtlichen Weise schräg an der Schwenkwelle 28 an. Die von der Zugstange 23 aufgrund der Wirkung der Auslösefeder 12 auf die Schwenkwelle 28 in Richtung der Wirkungslinie 19 ausgeübte Kraft K wird daher in eine nach vorn gerichtete horizontale Komponente A, die die Auslösekraft bestimmt, und in eine vertikal nach unten gerichtete relativ kleine Komponente N verlegt. Die Größe der kraftkomponente N im Verhältnis zu der Kraftkomponente A hängt von dem Winkel α ab, den der untere Ast 16′ der Kippachsen 16 in der Seitenansicht der Fig. 1 mit der Wirkungslinie 19 einschließt. Bei dem dargestellten Ausführungsbeispiel beträgt dieser Winkel α=75°.The operation of the toe piece described is as follows:
Due to the inclination of the line of action 19 of the release spring 12 and the inclination of the pivot shaft 28 in such a way that its upper end is closer to the ski boot 14 than in the case of a vertical arrangement on the surface of the ski 15, the pull rod 23 engages in the one shown in FIG. 1 Way at an angle to the pivot shaft 28. The force K exerted by the pull rod 23 due to the action of the release spring 12 on the pivot shaft 28 in the direction of the line of action 19 is therefore converted into a forward-facing horizontal component A, which determines the release force, and into a relatively small component N directed vertically downward relocated. The size of the force component N in relation to the force component A depends on the angle α, which the lower branch 16 'of the tilt axes 16 includes in the side view of FIG. 1 with the line of action 19. In the illustrated embodiment, this angle is α = 75 °.

Die vertikal nach unten gerichtete Kraftkomponente N versucht den Sohlenhalter 18 entlang der Kippflächen 20 (Fig. 2) nach unten zu ziehen. Zweckmäßigerweise bestehen die Kippflächen 17, 20 aus reibungsarmem Material, so daß die Kraftkomponente N die Reibung zwischen den Kippflächen 17, 20 überwinden kann.The vertically downward force component N tries to pull the sole holder 18 downwards along the tilting surfaces 20 (FIG. 2). The tilting surfaces 17, 20 expediently consist of low-friction material, so that the force component N can overcome the friction between the tilting surfaces 17, 20.

Ohne eingestellten Skischuh befindet sich also der Sohlenhalter 18 in seiner untersten Stellung, die beispielsweise durch einen unter dem Sohlenhalter angeordneten Anschlag 51' bestimmt sein kann.Without an adjusted ski boot, the sole holder 18 is in its lowermost position, which can be determined, for example, by a stop 51 'arranged under the sole holder.

Wird in die so ausgebildete Bindung ein Skistiefel 14 eingestellt, so wird der vordere Bereich der Sohle 22 schräg von oben in den Spalt zwischen dem Niederhalter 21 und der Trittplatte 34 eingeschoben, wobei der unterhalb des Niederhalters 21 vorhandene Freiraum 52 gewährleistet, daß der Skistiefel in dieser Weise ohne zu großen Widerstand derart eingeführt werden kann, daß die Sohle 22 sich unter dem Niederhalter 21 bis zur Anlage an den vorderen Abstützrollen 47 einschieben läßt. Dabei legen sich die Seitenränder der Sohle 22 an die seitlichen Abstützrollen 46 an und spreizen die beiden Hälften 18′, 18˝ des Sohlenhalters 18 gerade soweit, daß die Vorderfläche der Sohle 22 an den vorderen Abstützrollen 47 zur Anlage kommt.If a ski boot 14 is inserted into the binding formed in this way, the front area of the sole 22 is inserted obliquely from above into the gap between the hold-down device 21 and the tread plate 34, the space 52 below the hold-down device 21 ensuring that the ski boot can be introduced in this way without excessive resistance such that the sole 22 can be inserted under the holding-down device 21 until it abuts the front support rollers 47. The side edges of the sole 22 lie against the lateral support rollers 46 and spread the two halves 18 ', 18' of the sole holder 18 just enough that the front surface of the sole 22 comes into contact with the front support rollers 47.

Anschließend wird dann die nicht dargestellte Ferse des Skistiefels 14 abwärts gesenkt, worauf die Sohle 22 mit ihrer Unterseite auf der Trittplatte 34 zur Auflage kommt und der obere vordere Rand der Sohle 22 den Niederhalter 21 soweit wie erforderlich anhebt, wobei der Sohlenhalter 18 insgesamt entlang der Kippachsen 16 etwas nach oben gleitet.Then the heel of the ski boot 14, not shown, is then lowered, whereupon the sole 22 comes to rest with its underside on the tread plate 34 and the upper front edge of the sole 22 raises the hold-down 21 as far as necessary, the sole holder 18 as a whole along the Tilt axis 16 slides slightly upwards.

Sowohl beim Auseinanderspreizen der Hälften 18′, 18˝ des Sohlenhalters 18 als auch beim geringfügigen Hochgleiten des Sohlenhalters 18 an den Kippflächen 20 wird die Auslösefeder 12 etwas stärker gespannt, wobei der Anzeigefortsatz 25 sich relativ zur Auslösehärteskala 26 etwas in Fig.1 nach rechts verschiebt. Die etwas erhöhte Auslösehärte wird somit angezeigt und kann durch entsprechende Verdrehung des Schraubenkopfes 43 wieder vermindert werden.Both when spreading apart the halves 18 ', 18' of the sole holder 18 and when the sole holder 18 slides up slightly on the tilting surfaces 20, the release spring 12 is tensioned somewhat more, the display extension 25 shifting somewhat to the right in FIG. 1 relative to the release hardness scale 26 . The somewhat increased release hardness is thus displayed and can be reduced again by turning the screw head 43 accordingly.

Aufgrund der erfindungsgemäßen Ausbildung wird also die Sohle 22 des Skistiefels 14 zwischen dem Niederhalter 21 und der Trittplatte 34 zangenartig eingespannt, wobei die Zangenkraft von der Kraftkomponente N, die von der Auslösefeder 12 stammt, geliefert wird.Because of the design according to the invention, the sole 22 of the ski boot 14 is clamped like pliers between the hold-down device 21 and the tread plate 34, the force of the pliers being supplied by the force component N, which originates from the release spring 12.

Die Seitenauslösung kann nun wie bei einem derartigen Kippbacken üblich durch Schwenken um eine der Kippachsen 16 erfolgen. Die Auslösekraft wird dabei durch die Kraftkomponente A bestimmt.The side can now be triggered, as is customary with such a tilting jaw, by pivoting about one of the tilting axes 16. The triggering force is determined by the force component A.

Gerät der Skifahrer in Rücklage, so kann die Sohle 22 über den Niederhalter 21 den Sohlenhalter 18 nach oben verschieben, wobei der Druck von der Sohle 22 auf die Trittplatte 34 aufgehoben wird.If the skier is in reserve, the sole 22 can move the sole holder 18 upward via the hold-down device 21, the pressure from the sole 22 on the tread plate 34 being released.

Sobald die Höhenkippgegenfläche 32 den Höhenkippanschlag 31 erreicht, kann der Sohlenhalter 18 um eine am Höhenkippanschlag 31 vorhandene Querachse nach oben schwenken und den Skistiefel 14 freigeben.As soon as the countertop surface 32 reaches the end stop 31, the sole holder 18 can pivot upward about a transverse axis present at the end stop 31 and release the ski boot 14.

Wird der Schieber 33 vor Inbetriebnahme der Bindung in Richtung des Pfeiles in die gestrichelt dargestellte Position verschoben, so stößt die Höhenkippgegenfläche schon bei einer geringeren Vertikalverschiebung des Sohlenhalters 18 oben gegen den Höhenkippanschlag 31, was wegen des nunmehr vorhandenen größeren Hebelarmes zu einer größeren Höhenauslösehärte führt.If the slider 33 is moved in the direction of the arrow into the position shown in dashed lines before the binding is put into operation, then the countertop of the vertical tilting abuts against the vertical tilting stop 31 at a slight vertical displacement of the sole holder 18, which leads to a greater level of hardness due to the larger lever arm now present.

Bei einer Vorlage des Skifahrers drückt die Schuhsohle 22 in Richtung des Pfeiles f auf die Trittplatte 34 nach unten, wodurch über die Keilflächen 50, 50′ und den Keil 36′ die Druckstange 36˝ nach vorn geschoben wird. Dies führt über den Winkelhebel 36‴ zu einer Verschiebung des Sohlenhalters 18 entlang der Kippachsen 16 nach oben. Hierdurch verschwindet der Druck des Niederhalters 21 von oben auf die Sohle 22, so daß auch die dort normalerweise vorhandene Reibung entfällt und nunmehr noch die Reibung zwischen der Sohle 22 und dem Belag 35 der Trittplatte 34 vorhanden ist. Dadurch wird eine gleichbleibende oder sogar erniedrigte Seitenauslösekraft gewährleistet, so daß es im Falle eines kombinierten Vorwärts-Drehsturzes zu einer vorzugsweise erleichterten Seitenauslösung der Bindung kommt.When presenting the skier, the shoe sole 22 presses in the direction of arrow f onto the tread plate 34, whereby the push rod 36 'is pushed forward over the wedge surfaces 50, 50' and the wedge 36 '. This leads via the angle lever 36 ‴ to a displacement of the sole holder 18 along the tilt axes 16 upwards. As a result, the pressure of the hold-down 21 disappears from above onto the sole 22, so that the friction normally present there is also eliminated and the friction between the sole 22 and the covering 35 of the tread plate 34 is still present. This ensures a constant or even reduced side release force, so that in the case of a combined forward turn, the side release of the binding is preferably facilitated.

Um auch die Reibung zwischen dem Niederhalter 21 und der Oberseite der Sohle 22 gering zu halten, ist unterhalb des Niederhalters 21 ebenfalls ein reibungsmindernder Belag 53 vorzugsweise aus Teflon vorgesehen.In order to keep the friction between the hold-down 21 and the top of the sole 22 low, is below the Hold-down device 21 also has a friction-reducing covering 53, preferably made of Teflon.

Wenn der Schieber 33 durch die in Fig. 1 gestrichelt dargestellte Position verschoben worden ist, steht der Betätigungshebel 49 nach oben über das Bindungsgehäuse 11 vor. Er kann jetzt durch Drücken mit dem Finger oder dem Skistock nach unten wieder in die aus Fig. 1 ersichtliche Lage verschoben werden, wobei der Schieber 33 in die in Fig. 1 mit ausgezogenen Linien dargestellte schuhnahe Lage vorgeschoben wird und die Höhenkippgegenfläche 32 erneut zur Wirkung kommt.When the slide 33 has been displaced by the position shown in dashed lines in FIG. 1, the actuating lever 49 projects upward beyond the binding housing 11. It can now be pushed back down into the position shown in FIG. 1 by pressing it with the finger or the ski stick, the slider 33 being advanced into the position close to the shoe shown in solid lines in FIG. 1 and the countertop surface 32 again effective is coming.

Beim Ausführungsbeispiel nach Fig. 3 bezeichnen gleiche Bezugszahlen entsprechende Teile wie beim vorangehend beschriebenen Ausführungsbeispiel.In the exemplary embodiment according to FIG. 3, the same reference numerals designate corresponding parts as in the exemplary embodiment described above.

Aufbau und Funktion der Ausführungsform nach Fig.3 sind bis auf den Reibungskompensator mit dem Kraftumlenkgetriebe 36′, 36˝, 36‴ gleich wie bei der Ausführungsform nach den Fig. 1, 2.The structure and function of the embodiment according to FIG. 3 are the same as in the embodiment according to FIGS. 1, 2, except for the friction compensator with the power deflection gear 36 ', 36˝, 36 ‴.

Bei der Ausführungsform nach Fig. 3 und 4 ist die Trittplatte 34′ in einer Führung 54 querverschiebbar auf der Skioberfläche gelagert. In der Mitte der Trittplatte greift eine unterhalb einer Deckplatte 55 auf der Oberfläche des Ski angebrachte Spreizfeder 56 in Skilängsrichtung durch eine begrenzte Schlitzöffnung 57 in eine untere Ausnehmung 58 der Trittplatte 34′ ein,die jedoch seitlich durch Anschläge 59 in der aus Fig. 4 ersichtlichen Weise begrenzt ist. Da die sicherheitsnadelförmig ausgebildete Spreizfeder 56 in der aus Fig. 4 ersichtlichen Ruhelage an den Rändern des Schlitzes 57 und gleichzeitig an den Seitenanschlägen 59 der Trittplatte 34′ anliegt, befindet sich die Trittplatte 34′ in einer stabilen Mittelposition. Sie kann jedoch nach beiden Seiten gegen die relativ geringen Rückstellkräfte der Spreizfeder 56 innerhalb des Bewegungsspielraums der Spreizfeder 56 verschoben werden.In the embodiment according to FIGS. 3 and 4, the tread plate 34 'is mounted on the ski surface so as to be displaceable in a guide 54. In the middle of the tread plate, a spreading spring 56 attached below a cover plate 55 on the surface of the ski engages in the longitudinal direction of the ski through a limited slot opening 57 into a lower recess 58 of the tread plate 34 ', which, however, can be seen laterally through stops 59 in FIG. 4 Way is limited. Since the safety pin-shaped spreading spring 56 in the rest position shown in FIG. 4 rests on the edges of the slot 57 and at the same time on the side stops 59 of the tread plate 34 ', the tread plate 34' is in a stable middle position. However, it can be moved on both sides against the relatively low restoring forces of the spreading spring 56 within the range of motion of the spreading spring 56.

Der seitliche Verschiebebereich der Trittplatte 34′ ist so bemessen, daß bei einer Seitenauslösung das Ende des Verschiebebereiches der Trittplatte 34′ erst dann erreicht wird, wenn die auf den Sohlenhalter 18 von der Auslösefeder 12 ausgeübte Rückstellkraft bereits soweit abgesunken ist, daß die Summe der verbleibenden Rückstellkraft und der Reibung zwischen der Schuhsohle 22 und dem reibungsarmen Belag 35 deutlich geringer ist als die Auslösekraft. Auf diese Weise sind die Auswirkungen der Reibung zwischen der Sohle 22 und der Trittplatte 34′ im kritischen Bereich der Seitenauslösung vernachlässigbar gering.The lateral displacement area of the tread plate 34 'is dimensioned such that, in the event of a side release, the end of the displacement area of the tread plate 34' is only reached when the restoring force exerted on the sole holder 18 by the release spring 12 has already dropped to such an extent that the sum of the remaining ones Restoring force and the friction between the shoe sole 22 and the low-friction covering 35 is significantly less than the triggering force. In this way, the effects of friction between the sole 22 and the tread plate 34 'in the critical region of the side release are negligible.

Erfindungsgemäß ist hinter der Trittplatte 34′ noch eine Nottrittfläche 39 vorgesehen, deren Oberfläche etwas niedriger liegt als die Oberfläche des reibungsarmen Belages 35. Sollte die Trittplatte 34′ aus ihrer Führung 54 herausspringen und verlorengehen, so steht dann noch die Nottrittfläche 39 zur Abstützung der Schuhsohle 22 zur Verfügung. Die geringfügige Höhendifferenz zwischen dem Belag 35 und der Nottrittfläche 39 wird durch die Zangenwirkung des erfindungsgemäßen Backens problemlos ausgeglichen.According to the invention, an emergency tread surface 39 is provided behind the tread plate 34 ', the surface of which is somewhat lower than the surface of the low-friction covering 35. If the tread plate 34' jump out of its guide 54 and get lost, then the emergency tread surface 39 is then also used to support the shoe sole 22 available. The slight difference in height between the covering 35 and the emergency tread surface 39 is easily compensated for by the forceps effect of the baking according to the invention.

Die Führung 54 besteht zweckmäßigerweise aus Blech, wodurch ein geringer Reibwert zwischen der aus Kunststoff bestehenden Trittplatte 34′ und der Führung 54 erzielt wird. Für den Fall, daß die Trittplatte 34′ in der Führung 54 durch Gefrieren oder Korrosion oder auch durch mechanische Beschädigung der Führung 54 festklemmt, bleibt der Widerstand gegen eine Seitenbewegung der Sohle 22 dennoch gering, weil der reibungsarme Belag 35 vorgesehen ist.The guide 54 is advantageously made of sheet metal, whereby a low coefficient of friction between the plastic foot plate 34 'and the guide 54 is achieved. In the event that the tread plate 34 'clamps in the guide 54 by freezing or corrosion or also by mechanical damage to the guide 54, the resistance to a lateral movement of the sole 22 remains low because the low-friction coating 35 is provided.

Der seitliche Bewegungsbereich der Trittplatte nach einer Seite beträgt etwa 15 mm. Anschließend wird dann der Widerstand gegen eine weitere Seitwärtsbewegung der Sohle 22 durch die Reibung zwischen der Sohle 22 und dem Belag 35 bestimmt.The lateral range of movement of the tread plate to one side is approximately 15 mm. The resistance to a further sideways movement of the sole 22 is then determined by the friction between the sole 22 and the covering 35.
