Abstract

A front clip for a safety binding with a housing base (3) securable to a ski and a housing top (2) which has at least one adjustable release spring (4) and two pivoting sole holders (14a, 14b) on which said release spring acts, in which, with the front clip in its operative position, the housing top (2) can pivot about a transverse axis (Q) running substantially perpendicularly to the longitudinal central axis (L) of the front clip and the pivoting range of the housing top in relation to the housing base is limited by a horizontally movably fitted locking member (15, 115) in the base (3) or top (2) of the housing with at least one stop surface (32a1, 32b1, 32a2, 32b2, 32a3, 32b3, 32a4, 32b4). Said locking member (15, 115) co-operates, with the ski binding in the operative position, with a stop (29a, 29b) on the top or base of the housing so that the pivoting movement of the housing top in relation to the base is restricted in this position.

Description

Die Erfindung betrifft einen Vorderbacken für eine Sicherheitsbindung, mit einem an einem Ski befestigbaren Gehäuseunterteil und einem Gehäuseoberteil, welcher zumindest eine einstellbare Auslösefeder und zwei schwenkbare, von dieser Auslösefeder beaufschlagte Sohlenhalter aufweist, wobei der Gehäuseoberteil in der Gebrauchsstellung um eine im wesentlichen normal zur Längsmittelachse des Vorderbackens liegende Querachse verschwenkbar ist und die Verschwenkbarkeit des Gehäuseoberteils bezüglich des Gehäuseunterteils durch ein Verriegelungsmittel begrenzt ist.The invention relates to a toe piece for a safety binding, with a lower part of the housing which can be fastened to a ski and an upper part which has at least one adjustable release spring and two pivotable sole holders which are acted upon by this release spring, the upper part of the housing in the position of use around a substantially normal to the longitudinal central axis of the Front jaw lying transverse axis is pivotable and the pivotability of the upper housing part with respect to the lower housing part is limited by a locking means.

Ein Vorderbacken, bei welchem durch Verschwenken des Gehäuseoberteils bezüglich des Gehäuseunterteils eine Anpassung der Höhenlage der Sohlenhalter an die Höhe der Schuhsohle möglich ist, geht aus der DE-OS 39 37 363 hervor. Bei diesem bekannten Vorderbacken ist der Gehäuseoberteil einstückig mit dem Gehäuseunterteil ausgebildet, wobei sich im vorderen Bereich des Backens ein biegeelastischer Bereich befindet, welcher eine begrenzte Verschwenkbarkeit des Oberteils des Vorderbackens zur Anpassung der Lage der Sohlenniederhalter an die Sohlenhöhe ermöglicht. Dieser biegeelastische Bereich wird durch einen horizontalen Schlitz erzeugt, welcher im Vorderteil des Backens zwischen der Auslösefeder und der Skioberfläche ausgebildet ist. Das Verrieglungsmittel ist einerseits durch eine nach hinten vorspringede, mit dem Gehäuseoberteil einstückig ausgebildete Nase und andererseits durch einen federbelasteten in dem Gehäuseunterteil gelagerten Kipphebel oder eine nach vorne vorspringende, mit dem Gehäuseunterteil einstückig ausgebildete Nase realisiert.A toe piece, in which an adjustment of the height of the sole holder to the height of the shoe sole is possible by pivoting the upper part of the housing relative to the lower part of the housing, is apparent from DE-OS 39 37 363. In this known toe piece, the upper part of the housing is formed in one piece with the lower part of the case, with a resilient area in the front area of the cheek piece, which allows the upper part of the toe piece to be pivoted to a limited extent in order to adapt the position of the sole hold-down device to the sole height. This flexurally elastic region is created by a horizontal slot which is formed in the front part of the jaw between the release spring and the ski surface. The locking means is realized, on the one hand, by a nose projecting towards the rear, which is formed in one piece with the upper housing part, and, on the other hand, by a spring-loaded rocker arm mounted in the lower housing part or a projecting nose which is formed in one piece with the lower housing part.

Eine solche Vorrichtung besitzt eine Reihe von Nachteilen. Durch den obengenannten Schlitz wird die Festigkeit des Gehäuses der Skibindung geschwächt, wodurch es dort leicht zu einer Materialermüdung und folglich zu einem Bruch des Gehäuses kommen kann. Weiters ist die Verschwenkbarkeit des Gehäuses bei Verschmutzung oder Vereisung dieses Schlitzes blockiert, wobei die Bruchgefahr durch eine Überbelastung der Sohlenniederhalter zusätzlich ansteigt. Durch das einstückig angeformte Verriegelungsmittel ist der Vorderbacken weiters komplex aufgebaut und daher dementsprechend aufwendig herzustellen.Such a device has a number of disadvantages. The strength of the housing of the ski binding is weakened by the above-mentioned slot, as a result of which material fatigue and consequently breakage of the housing can easily occur. Furthermore, the pivotability of the housing is blocked when this slot is dirty or iced up, the risk of breakage additionally increasing due to overloading of the sole hold-down device. Due to the one-piece molded locking means, the front jaw is also complex and therefore expensive to manufacture.

Ein aus zwei Gehäuseteilen bestehender Vorderbacken, der durch Verschwenken eines Gehauseteils bezüglich des anderen um eine Querachse zusammengesetzt wird, ist aus der DE-OS 39 42 157 bekannt geworden. In der Gebrauchsstellung werden die zwei Gehäuseteile dann mittels einer vertikal angeordneten Schraube miteinander verschraubt, wobei mittels dieser Schraube gleichzeitig die Höheneinstellung der Sohlenhalter vorgenommen wird. Diese Schraube und das in dem Gehäuseunterteil vorgesehene Gegengewinde bilden somit das Verriegelungsmittel für diesen bekannten Vorderbacken. Ein Nachteil dieser Vorrichtung liegt darin, daß die Sohlenhalter bei Verwendung unterschiedlicher Skischuhe für jeden Schuh von einem Servicemann erneut eingestellt werden müssen. Überdies wird durch die von oben gesehen zentral angeordnete Schraube eine konstruktiv günstige Anordnung der Auslösefeder verhindert.A front jaw consisting of two housing parts, which is assembled by pivoting one housing part relative to the other about a transverse axis, has become known from DE-OS 39 42 157. In the position of use, the two housing parts are then screwed to one another by means of a vertically arranged screw, with the screw simultaneously adjusting the height of the sole holder. This screw and the counter thread provided in the lower housing part thus form the locking means for this known front jaw. A disadvantage of this device is that the sole holder must be readjusted by a service man when using different ski boots for each shoe. In addition, the centrally arranged screw prevents a structurally advantageous arrangement of the release spring.

Eine weitere Vorrichtung, welche eine Veränderung der Höhenlage der Sohlenniederhalter eines Vorderbackens ermöglicht, wird in der AT-PS 361 823 beschrieben. Bei dieser Vorrichtung ist oberhalb der Auslösefeder an einer Querachse ein von einer Feder beaufschlagter Niederhaltearm schwenkbar angeordnet. An diesem Niederhaltearm sind höhenverstellbare Sohlenniederhalter angebracht. Die durch Verschwenkung des Niederhaltearmes entstehende Höhenveränderung der Sohlenniederhalter dient bei dieser Vorrichtung jedoch dazu, im Auslösefall den Skischuh nach oben freizugeben, und nicht zur Anpassung der Skibindung an unterschiedliche Schuhsohlen, welche nach wie vor mittels Verstellschrauben vorgenommen wird. Diese Vorrichtung ist also für eine automatische Anpassung der Sohlenniederhalter an unterschiedliche Schuhsohlen nicht geeignet und weist überdies Nachteile auf, zum Beispiel können die seitlichen Sohlenhalterungen und die Sohlenniederhalter nicht einstückig ausgebildet werden.A further device which enables a change in the height of the sole hold-down device of a toe piece is described in AT-PS 361 823. In this device, a hold-down arm acted upon by a spring is pivotably arranged on a transverse axis above the release spring. Height-adjustable sole hold-down devices are attached to this hold-down arm. However, the change in height of the sole hold-down device that occurs due to the pivoting of the hold-down arm in this device serves to release the ski boot upwards in the event of a release, and not to adapt the ski binding to different shoe soles, which is still carried out by means of adjusting screws. This device is therefore not suitable for automatic adaptation of the sole hold-down devices to different shoe soles and moreover has disadvantages, for example the side sole holders and the sole hold-down devices cannot be formed in one piece.

Das ordnungsgemäße Funktionieren eines Vorderbackens einer Skibindung hängt sehr stark von seiner richtigen Einstellung ab. Besonders kritisch ist die Einstellung der Höhe der Sohlenhalter, welche zumeist von einem Servicetechniker durchgeführt wird. Diese Einstellung ist sehr zeitraubend, da sie äußerst exakt vorgenommen werden muß, um nicht das Auslöseverhalten des Vorderbackens zu beeinflussen.The proper functioning of a front binding of a ski binding depends very much on its correct setting. The adjustment of the height of the sole holder, which is usually carried out by a service technician, is particularly critical. This setting is very time consuming, since it has to be carried out extremely precisely so as not to influence the trigger behavior of the toe piece.

Eine Aufgabe der Erfindung ist es, einerseits den Zusammenbau eines Vorderbackens für eine Skibindung zu vereinfachen und andererseits die durch die Verschwenkbarkeit der beiden Gehäuseteile ermöglichte automatische Höheneinstellung der Sohlenhalter nach oben zu begrenzen.An object of the invention is, on the one hand, to simplify the assembly of a toe for a ski binding and, on the other hand, to limit the automatic height adjustment of the sole holder made possible by the pivotability of the two housing parts.

Insbesondere ist es eine Aufgabe der Erfindung, eine möglichst einfache und kompakte Anordnung zu finden, welche bei einfachem Zusammenbau des Vorderbackens gleichzeitig eine automatische Anpassung der Höhenlage der Sohlenniederhalter an die Höhe der Schuhsohle ermöglicht und das Verhalten der Auslösefeder dabei nicht beeinträchtigt.In particular, it is an object of the invention to find a configuration which is as simple and compact as possible and which, at the same time, is a simple assembly of the toe piece automatic adjustment of the height of the sole hold-down to the height of the shoe sole enables and the behavior of the release spring is not affected.

Erfindungsgemäß geschieht dies mittels eines Vorderbackens der eingangs genannten Art, bei welchem das Verrieglungsmittel ein in dem Gehäuseunterteil oder dem Gehäuseoberteil horizontal verschiebliches Verriegelungsstück mit zumindest einer Anschlagfläche aufweist, welches in der Gebrauchsstellung der Skibindung mit einem an dem Gehäuseoberteil oder dem Gehäuseunterteil vorgesehenen Anschlag zusammenwirkt, wodurch die Verschwenkbewegung des Gehäuseoberteils bezüglich des Gehäuseunterteils in dieser Stellung begrenzt ist.According to the invention, this is done by means of a front jaw of the type mentioned at the outset, in which the locking means has a locking piece with at least one stop surface which can be displaced horizontally in the lower housing part or the upper housing part and which, in the use position of the ski binding, interacts with a stop provided on the upper housing part or the lower housing part, as a result of which the pivoting movement of the upper housing part with respect to the lower housing part is limited in this position.

Das horizontal verschiebliche Verriegelungsstück bietet den Vorteil, den Vorderbacken durch Voreinstellen einer Gebrauchsstellung bereits in einer gebrauchsfertigen Form auszuliefern, wobei der Servicemann gegebenenfalls erforderliche Einstellungen in bezug auf die Verschwenkbarkeit des Gehäuseoberteils mittels dieses Verriegelungsstückes sehr rasch und dennoch exakt vornehmen kann. Weiters bietet diese Lösung zusätzlich Vorteile bei einer Rückwärts- bzw. Diagonalauslösung des Vorderbackens.The horizontally displaceable locking piece offers the advantage of delivering the front jaws in a ready-to-use form by presetting a position of use, whereby the serviceman can make any necessary adjustments regarding the pivotability of the upper housing part very quickly and yet precisely by means of this locking piece. This solution also offers additional advantages when the toe piece is triggered backwards or diagonally.

Die erfindungsgemäße Lösung kann hinsichtlich des Verriegelungsstückes in unterschiedlichen Ausführungsformen realisiert sein. Im einfachsten Fall besitzt das Verriegelungsstück eine einzige horizontale Anschlagfläche, wogegen weitere Ausführungen zumindest zwei unterschiedliche Anschlagflächen aufweisen, von denen wahlweise eine zur Begrenzung der Verschwenkbewegung des Gehäuseoberteils bezuglich des Gehäuseunterteils dient. Somit kann diese Verschwenkbewegung auf ein vorgebbares Maß eingeschränkt werden. Durch diese Maßnahme wird zusätzlich die Stabilität des Skishuhes im Vorderbacken erhöht.The solution according to the invention can be implemented in different embodiments with regard to the locking piece. In the simplest case, the locking piece has a single horizontal stop surface, whereas other versions have at least two different stop surfaces, one of which optionally serves to limit the pivoting movement of the upper housing part with respect to the lower housing part. This pivoting movement can thus be restricted to a predeterminable amount. This measure also increases the stability of the ski boot in the toe.

Eine besonders vorteilhafte Ausführungsform eines erfindungsgemäßen Vorderbackens ist jene, bei welcher in dem Gehäuseober- und/oder Gehäuseunterteil eine Feder vorgesehen ist, welche die Verschwenkbewegung des Gehäuseoberteils bezüglich des Gehäuseunterteils in Richtung Gebrauchsstellung beaufschlagt. Diese Federkraft kann entweder die Auslösefeder selbst sein, welche über einen Federhebel an dem Gehäuseunterteil wirkt, oder es kann zu diesem Zweck eine gesonderte Feder, insbesondere eine Blattfeder vorgesehen sein, welche zwischen Gehäuseober- und Gehäuseunterteil wirkt. Durch diese Federkraft wird die Höhe der Sohlenhalter automatisch und stufenlos auf die Höhe der Skischuhsohle eingestellt, wenn der Benützer mit seinem Skischuh in die Bindung einsteigt.A particularly advantageous embodiment of a front jaw according to the invention is that in which a spring is provided in the upper and / or lower housing part, which acts on the pivoting movement of the upper housing part with respect to the lower housing part in the direction of the use position. This spring force can either be the release spring itself, which acts on the lower housing part via a spring lever, or a separate spring, in particular a leaf spring, can be provided for this purpose, which acts between the upper housing part and the lower housing part. This spring force automatically and continuously adjusts the height of the sole holder to the height of the ski shoe sole when the user steps into the binding with his ski shoe.

Weitere Details und Ausgestaltungsmerkmale des erfindungsgemäßen Vorderbackens ergeben sich aus den abhängigen Unteransprüchen.Further details and design features of the toe piece according to the invention result from the dependent subclaims.

Bei der Neuentwicklung von Skibindungen mussen im allgemeinen mehrere Faktoren berücksichtigt werden. Bisher waren solche Faktoren zum Beispiel die Betriebssicherheit und damit zusammenhängende neue technische Merkmale oder eine einfache und kostengünstige Fertigung unter Beibehaltung der erforderlichen technischen Funktionsmerkmale. Während der letzten Jahre ist jedoch noch ein weiterer Faktor hinzugekommen, nämlich eine rasche und genaue Verstellbarkeit der Bindung, wobei vor allem im Verleihbetrieb zumeist gefordert wird, daß die Skibindung mit wenigen Handgriffen oder gar automatisch an unterschiedliche Skischuhe bzw. Benützer angepaßt werden kann. Die im folgenden anhand unterschiedlicher Ausführungsformen erläuterte Erfindung bezieht sich auf einen Vorderbacken mit automatischer Höheneinstellung der Sohlenhalter, wobei dieser Vorderbacken kostengünstig gefertigt und einfach zusammengebaut werden kann.

When developing new ski bindings, several factors generally have to be taken into account. So far, such factors have been, for example, operational safety and related new technical features or simple and inexpensive production while maintaining the required technical functional features. Over the past few years, however, another factor has been added, namely a quick and precise adjustability of the binding, whereby, especially in the rental business, it is usually required that the ski binding can be adapted to different ski shoes or users with a few hand movements or even automatically. The invention explained below on the basis of different embodiments relates to a toe piece with automatic height adjustment of the sole holder, this toe piece being inexpensive to manufacture and simple to assemble.

Vorerst wird auf die Figuren 1 und 2 Bezug genommen, weiche schematisch einen erfindungsgemäßen Vorderbacken 1 darstellen, der aus einem Gehäuseoberteil 2 und einem Gehäuseunterteil 3 besteht. In dem Gehäuseoberteil 2 ist zwischen einem vorderen und einem hinteren Federabstützteller 6 bzw. 7 eine Auslösefeder 4 gelagert, wobei der vordere Federabstützteller 6 sich über das Auslösesystem am Gehäuseoberteil abstützt und der hintere Federabstützteller 7 über eine Einsteilschraube 5 mit der Stirnseite des Gehäuseoberteils 2 mechanisch verbunden ist. Der Oberteil des hinteren Federabstütztellers ist als Zeiger ausgebildet und zeigt dem Benützer über ein an der Oberseite des Gehäuseoberteils gelegenes Fenster 10 die anhand der Einstellschraube 5 eingestellte Vorspannung der Auslösefeder 4 an. Zwischen der Auslösefeder 4 und dem hinteren Federabstützteller 7 sind bei dem hier dargestellten Ausführungsbeispiel zusätzlich ein Federhebel 8 und eine Lagerscheibe 9 eingefügt, wobei sich der winkelförmige Federhebel 8 an dem hinteren Federabstützteller 7 abstützt und über die Lagerscheibe 9 an der Auslösefeder wirkt. Die erfindungsgemäße Wirkung dieses Federhebeis 8 wird weiter unten naher erläutert. Weiters ist zwischen dem vorderen Federabstützteller 6 und der Stirnseite des Gehäuseoberteils 2 ein Winkel 12 eines Zugstückes 11 eingefügt. An dem anderen Ende des länglichen Zugstückes 11 greift ein vertikaler Bolzen 13 an, an welchem die Sohlenhalter 14a, 14b des Vorderbackens gelagert sind. Die Sohlenhalter 14a, b sind so an dem Gehäuseoberteil gelagen, daß eine Seiten-, Rückwärts- und Diagonalauslösung des Vorderbackens möglich ist. Die Wirkungsweise dieser Sohlenhalter ist jedoch nicht Teil dieser Erfindung und wird deshalb im weiteren hier nicht näher erläutert.For the time being, reference is made to FIGS. 1 and 2, which schematically represent a front jaw 1 according to the invention, which consists of an upper housing part 2 and a lower housing part 3. A release spring 4 is mounted in the upper housing part 2 between a front and a rear spring support plate 6 or 7, the front spring support plate 6 being supported on the upper housing part via the release system and the rear spring support plate 7 being mechanically connected to the end face of the upper housing part 2 via an adjusting screw 5 is. The upper part of the rear spring support plate is designed as a pointer and indicates to the user, via a window 10 located on the upper side of the upper housing part, the pretensioning of the release spring 4 set using the adjusting screw 5. In the exemplary embodiment shown here, a spring lever 8 and a bearing plate 9 are additionally inserted between the release spring 4 and the rear spring support plate 7, the angular spring lever 8 being supported on the rear spring support plate 7 and acting on the release spring via the bearing plate 9. The effect of this spring jack 8 according to the invention is explained in more detail below. Furthermore, an angle 12 of a tension piece 11 is inserted between the front spring support plate 6 and the end face of the upper housing part 2. At the other end of the elongated tension piece 11, a vertical pin 13 engages, on which the sole holders 14a, 14b of the toe piece are mounted. The sole holders 14a, b are located on the upper part of the housing in such a way that the toe piece can be released from the side, backwards and diagonally. However, the mode of operation of these sole holders is not part of this invention and is therefore not further explained here.

In den Figuren 3 bis 5 ist der Gehäuseunterteil 3 in verschiedenen Ansichten dargestellt, wobei in den Figuren 4 und 5 zusätzlich das in den Figuren 7 und 8 gesondert dargestellte Verriegelungsstück 15 zu sehen ist. Bei der in Figur 3 dargestellten Draufsicht des Gehäuseunterteils 3 ist eine zentrale Ausnehmung 16 für das Verriegelungsstück zu sehen. Im Vorderteil des Gehäuseunterteils sind im Bereich des Gehäuserandes zwei an einer Querachse Q und symmetrisch zur Längsmittelachse L liegende flache Lagerteile 17a, 17b angeordnet, die nach oben in abgerundete Lagerköpfe 18a, 18b übergehen (siehe Fig. 4). An der Innenseite dieser Lagerteile 17a, b ist in dem Gehäuseunterteil ein Einhakelement 19 in Form zweier Vorsprünge 20a, 20b ausgeformt. Zwischen diesen Vorsprüngen 20a, b sind an der Unterseite des Gehäuseunterteils hintereinander mehrere V-förmige Rastelemente 211, 212, 213, 214 vorgesehen, welche quer zur Längsmittelachse ausgerichtet sind. In Längsrichtung sind hinter den Vorsprüngen 20a, b in dem Gehäuseunterteil 3 zusätzlich längliche Aussparungen 22a, 22b ausgeformt, welche in unmittelbarer Nähe der Vorsprünge 20a, b in Durchbrüche 23a, 23b münden. In diese länglichen Aussparungen 22a, b greifen in der Gebrauchsstellung des Vorderbackens zwei mit den Vorsprüngen 20a, b in Anlage stehende Haken 28a, 28b des Gehauseoberteils 2 ein. An dem seitlichen Rand der Ausnehmung 16 für das Verriegelungsstück 15 sind weiters an dem Gehäuseunterteil Führungselemente 24a, b vorgesehen, an welchen das Verriegelungsstück 15 in Längsrichtung verschieblich gelagert ist. In den Figuren 4 und 5 ist das erfindungsgemäße Verriegelungsstück 15 bereits in dem eingebauten Zustand zu sehen. Einzelne Merkmale des Verriegelungsstückes 15 werden im folgenden mit Bezug auf die Figuren 7 bis 10 näher erläutert.FIGS. 3 to 5 show the lower housing part 3 in different views, with the locking piece 15 separately shown in FIGS. 7 and 8 also being shown in FIGS. 4 and 5. In the plan view of the lower housing part 3 shown in FIG. 3, a central recess 16 for the locking piece can be seen. Arranged in the front part of the lower housing part in the region of the housing edge are two flat bearing parts 17a, 17b lying on a transverse axis Q and symmetrical to the longitudinal central axis L, which pass upwards into rounded bearing heads 18a, 18b (see FIG. 4). A hooking element 19 in the form of two projections 20a, 20b is formed on the inside of these bearing parts 17a, b in the lower housing part. Between these projections 20a, b, a plurality of V-shaped latching elements 21 1 , 21 2 , 21 3 , 21 4 are provided on the underside of the lower housing part, which are aligned transversely to the longitudinal central axis. In the longitudinal direction, behind the projections 20a, b, elongated recesses 22a, 22b are additionally formed in the lower housing part 3, which open out in the immediate vicinity of the projections 20a, b into openings 23a, 23b. In the elongated recesses 22a, b, in the use position of the front jaw, two hooks 28a, 28b, which are in contact with the projections 20a, b Housing upper part 2 a. On the lateral edge of the recess 16 for the locking piece 15, guide elements 24a, b are further provided on the lower housing part, on which the locking piece 15 is slidably mounted in the longitudinal direction. 4 and 5, the locking piece 15 according to the invention can already be seen in the installed state. Individual features of the locking piece 15 are explained in more detail below with reference to FIGS. 7 to 10.

Figur 6 zeigt eine Unteransicht des Gehäuseoberteils 2 eines erfindungsgemäßen Vorderbackens 1, der hier ohne Auslösefeder 4 und Sohlenhalter 14a, b und anderen Teilen dargestellt ist. Im Vorderteil des Gehäuseoberteils 2 sind im Bereich des Gehäuserandes an der Querachse Q und symmetrisch zur Längsmittelachse L zwei sich konisch verengende Lagerstellen 25a, 25b angeordnet, die nach oben in abgerundete Lagerflächen 26a, 26b übergehen. Diese Lagersteilen 25a, b sind in der Gebrauchsstellung des Vorderbackens den Lagerteilen 17a, b zugeordnet und bilden zusammen mit diesen ein Gelenk, mittels welchem der Gehäuseoberteil 2 an dem Gehäuseunterteil 3 verschwenkbar und entnehmbar gelagert ist. Die Drehachse dieses Gelenks verläuft entlang der Querachse Q und geht durch die Mittelpunkte M der Lagerköpfe 18a, b bzw. der Lagerflächen 26a, b. In unmittelbarer Nähe der Lagerstellen 25a, b ist an dem Gehäuseoberteil ein Hakenelement 27 in Form zweier Haken 28a, 28b vorgesehen. In der Gebrauchsstellung des Vorderbackens greifen diese Haken 28a, b in die Vorsprünge 20a, b des Einhakelementes 19 ein und verhindern in dieser Gebrauchsstellung ein Abheben der Lagerflächen 26a, b von den Lagerköpfen 18a, b, wodurch das Gelenk zwischen Gehäuseober- und Gehäuseunterteil vollständig hergestellt ist. Im Hinterteil des Gehäuseoberteils 2 ist eine zentrale Führungsplatte 30 ausgebildet, entlang welcher der mit den Sohlenhaltern 14a, b versehene Bolzen 13 geführt ist. Die Führungsfläche dieser Führungsplatte 30 ist nach hinten konisch erweitert und ermöglicht somit zusätzlich zur Seiten- und Rückwärtsauslösung auch eine Diagonalauslosung des Vorderbackens, insbesondere bei Rückwartsdrehstürzen. Unterhalb der Führungsplatte 30 ist in dem Gehäuseoberteil 2 ein Anschlagblock mit zwei seitlichen Anschlagen 29a, 29b vorgesehen. In der Gebrauchsstellung des Vorderbackens 1 wirkt je ein solcher Anschlag 29a, b mit je einer Anschlagfläche 32a1, 32b1, 32a2, 32b2, 32a3, 32b3, 32a4, 32b4 des Verriegelungsstückes 15 zusammen.FIG. 6 shows a bottom view of the upper housing part 2 of a toe piece 1 according to the invention, which is shown here without a release spring 4 and sole holder 14a, b and other parts. In the front part of the upper housing part 2, two conically narrowing bearing points 25a, 25b are arranged in the region of the housing edge on the transverse axis Q and symmetrically to the longitudinal center axis L, which merge upwards into rounded bearing surfaces 26a, 26b. These bearing parts 25a, b are assigned to the bearing parts 17a, b in the use position of the front jaw and together with these form a joint by means of which the upper housing part 2 is pivotably and removably mounted on the lower housing part 3. The axis of rotation of this joint runs along the transverse axis Q and passes through the center points M of the bearing heads 18a, b or the bearing surfaces 26a, b. In the immediate vicinity of the bearing points 25a, b, a hook element 27 in the form of two hooks 28a, 28b is provided on the upper housing part. In the use position of the front jaw, these hooks 28a, b engage in the projections 20a, b of the hooking element 19 and prevent the bearing surfaces 26a, b from lifting off from the bearing heads 18a, b in this use position, as a result of which the joint between the upper and lower housing parts is completely produced is. In the rear part of the upper housing part 2, a central guide plate 30 is formed, along which the bolt 13 provided with the sole holders 14a, b is guided. The guide surface of this guide plate 30 is flared to the rear and thus, in addition to triggering from the side and back, also enables the front jaw to be drawn diagonally, particularly in the case of backward turning falls. Below the guide plate 30, a stop block with two side stops 29a, 29b is provided in the upper housing part 2. In the use position of the front jaw 1, each such stop 29a, b interacts with a stop surface 32a 1 , 32b 1 , 32a 2 , 32b 2 , 32a 3 , 32b 3 , 32a 4 , 32b 4 of the locking piece 15.

Die Figuren 7 und 8 bzw. 9 und 10 zeigen zwei unterschiedliche Ausführungsformen eines erfindungsgemäßen Verriegelungsstückes 15 bzw. 115. Beide Verriegelungsstücke sind gabelförmig ausgebildet und besitzen zwei Gabelarme 31a, 31b. Von oben betrachtet sind an der Unterseite jedes Gabelarmes 31a, b hintereinander Anschlagflächen 32a1, 32b1, 32a2, 32b2, 32a3, 32b3, 32a4, 32b4 angeordnet. In der Gebrauchsstellung des Vorderbackens wirkt je eine solche Anschlagfläche 32a1, 32b1, 32a2, 32b2, 32a3, 32b3, 32a4, 32b4 mit je einem Anschlag 29a, b zusammen. Durch die unterschiedliche Höherlage der hintereinander liegenden Anschlagflächen wird somit die Verschwenkbarkeit des Gehäuseoberteils 2 bezüglich des Gehäuseunterteils 3 auf ein vorbestimmtes Maß beschränkt. Die Einstellung erfolgt durch horizontales Verschieben des Verriegelungsstückes 15 bzw. 115. Weiters weisen diese Verriegelungsstücke 15, 115 seitlich an jedem Gabelarm 31a, b ausgeformte Kraftübertragungselemente 34a, 34b auf, welche in der Gebrauchsstellung des Vorderbackens mit den Führungen 24a, b zusammenwirken. Im zentralen Teil des Verriegelungsstückes 15 ist eine nach oben ragende Rastnase 23 vorgesehen, wogegen bei dem Verriegelungsstück 115 zwei symmetrisch zur Längsmittelachse liegende Rastnasen 133a, 133b vorgesehen sind. Diese Rastnasen sind in der Gebrauchsstellung des Vorderbackens in einer der V-förmigen Ausnehmungen 211, 212, 213, 214 eingerastet. Dadurch wird ein versehentliches Verschieben des Verriegelungsstückes in horizontaler Richtung verhindert. Weiters besitzt das Verriegelungsstück 15 bzw. 115 noch seitliche Gleitführungen 35a, 35b bzw. 135a, 135b und eine Handhabe 36 bzw. 136, mittels welcher die Horizontaleinstellung des Verriegelungsstückes von einem Servicetechniker vorgenommen werden kann. In einer hier nicht gezeigten Ausführungsform kann das Verriegelungsstück 15 bzw. 115 auch eine einzige horizontale Anschlagfläche aufweisen, wobei dann auf eine Handhabe am Verriegelungsstück verzichtet werden kann, da nur eine einzige Horizontalstellung sinnvoll ist und diese bereits beim Zusammenbau des Vorderbackens voreingestellt wird.Figures 7 and 8 or 9 and 10 show two different embodiments of a locking piece 15 or 115 according to the invention. Both locking pieces are fork-shaped and have two fork arms 31a, 31b. Viewed from above, stop surfaces 32a 1 , 32b 1 , 32a 2 , 32b 2 , 32a 3 , 32b 3 , 32a 4 , 32b 4 are arranged one behind the other on the underside of each fork arm 31a, b. In the use position of the front jaw, such a stop surface 32a 1 , 32b 1 , 32a 2 , 32b 2 , 32a 3 , 32b 3 , 32a 4 , 32b 4 each interacts with a stop 29a, b. Due to the different higher altitude one behind the other lying stop surfaces, the pivotability of the upper housing part 2 with respect to the lower housing part 3 is thus limited to a predetermined dimension. The adjustment is made by horizontally displacing the locking piece 15 or 115. Furthermore, these locking pieces 15, 115 have laterally formed force transmission elements 34a, 34b on each fork arm 31a, b, which cooperate with the guides 24a, b in the use position of the toe piece. In the central part of the locking piece 15, an upwardly projecting locking lug 23 is provided, whereas the locking piece 115 has two locking lugs 133a, 133b symmetrical to the longitudinal central axis. These locking lugs are locked in the use position of the front jaw in one of the V-shaped recesses 21 1 , 21 2 , 21 3 , 21 4 . This prevents inadvertent displacement of the locking piece in the horizontal direction. Furthermore, the locking piece 15 or 115 also has lateral sliding guides 35a, 35b or 135a, 135b and a handle 36 or 136, by means of which the horizontal adjustment of the locking piece can be carried out by a service technician. In an embodiment not shown here, the locking piece 15 or 115 can also have a single horizontal stop surface, it then being possible to dispense with a handle on the locking piece, since only a single horizontal position makes sense and this is already preset when the front jaw is assembled.

Sowohl bei dem in Fig. 1 gezeigten Ausführungsbeispiel als auch bei dem in Fig. 11 dargestellten Vorderbacken wirkt zwischen dem Gehäuseoberteil 2 und dem Gehäuseunterteil 3 eine Federkraft, welche in Verbindung mit dem Gelenk und dem Verriegelungsstück eine stufenlose Höhenanpassung der Sohlenhalter 14a, b an die Höhe der Skischuhsohle ermöglicht. Bei dem in Figur 1 dargestellten Ausführungsbeispiel wird die Federkraft von der Auslösefeder 4 bereitgestellt, wobei die zur automatischen Höheneinstellung der Sohlenhalter erforderliche Federwirkung über den Federhebel 8 auf den Gehäuseunterteil 3 übertragen wird. Der Federhebel 8 ist zweiarmig und von oben gesehen gabelförmig ausgebildet. Der erste Hebelarm des Federhebels 8 ist ein Lagerstück 40, mit dem der Federhebel an dem hinteren Federabstützteller 7 gelagert ist und über die Lagerscheibe 9 an der Auslösefeder 4 wirkt. Der zweite Hebelarm wird durch zwei winkelförmige Arme 41a, 41b gebildet, die mit dem Lagerstück 40 einstückig ausgebildet sind. Diese Arme führen -von oben gesehen- seitlich an der Auslösefeder vorbei zu dem Gehäuseunterteil 3. In der Gebrauchsstellung des Vorderbackens wirken die Arme 41a, b über zwei an ihren Enden ausgebildete und seitlich nach innen ragende Vorsprünge 42a, 42b an dem Gehäuseunterteil 3 bzw. dem Verriegelungsstück 15, welches in dem Gehäuseunterteil verschieblich gelagert ist. Die Wirkungsweise dieses Federhebels ist anhand der Fig. 1 leicht ersichtlich. Der Drehpunkt des Federhebels 8 liegt in dem mit X gekennzeichneten Punkt, der in dem unteren Bereich des Lagerstücks 40 liegt. Oberhalb der Einstellschraube 5, in dem oberen Bereich des Lagerstückes 40, wird dieses über die Lagerscheibe 9 von der Auslösefeder 4 in Pfeilrichtung beaufschlagt. Dadurch wird an den zweiten Hebelarmen 41a, b ein Moment erzeugt, welches an den Vorsprüngen 42a, 42b dieser Arme eine Kraft in Pfeilrichtung nach vorne erzeugt, wodurch der Gehäuseoberteil 2 in Richtung Gehäuseunterteil 3 belastet wird und die Sohlenhalter 14a, b somit in Pfeilrichtung nach unten gedrückt werden. Aus der in Fig. 1 gezeigten konstruktiven Anordnung geht klar hervor, daß die Höhenanpassung der Sohlenhalter die Auslösefeder 4 und somit das Auslöseverhalten des Vorderbackens nicht oder nur unwesentlich beeinflussen. Ebenso bleibt die Einstellung der Auslösefeder und die Anzeige derselben unangetastet.Both in the exemplary embodiment shown in FIG. 1 and in the front jaw shown in FIG. 11, a spring force acts between the upper housing part 2 and the lower housing part 3, which, in conjunction with the joint and the locking piece, enables the sole holder 14a, b to be continuously adjusted to the height Height of the ski boot sole allows. In the embodiment shown in Figure 1, the spring force is provided by the release spring 4, wherein the spring action required for automatic height adjustment of the sole holder is transmitted to the lower housing part 3 via the spring lever 8. The spring lever 8 has two arms and is fork-shaped as seen from above. The first lever arm of the spring lever 8 is a bearing piece 40, with which the spring lever is mounted on the rear spring support plate 7 and acts on the release spring 4 via the bearing disk 9. The second lever arm is formed by two angular arms 41a, 41b, which are formed in one piece with the bearing piece 40. Seen from above, these arms lead laterally past the release spring to the lower housing part 3. In the use position of the front jaw, the arms 41a, b act on the lower housing part 3 or via two projections 42a, 42b formed at their ends and projecting laterally inwards. the locking piece 15, which is slidably mounted in the lower housing part. The mode of operation of this spring lever can easily be seen from FIG. 1. The pivot point of the spring lever 8 lies in the point marked X, which lies in the lower region of the bearing piece 40. Above the adjusting screw 5, in the upper area of the bearing piece 40, this is acted upon by the release spring 4 in the direction of the arrow via the bearing disk 9. As a result, a moment is generated on the second lever arms 41a, b, which generates a force on the projections 42a, 42b of these arms in the direction of the arrow, whereby the upper housing part 2 is loaded in the direction of the lower housing part 3 and the sole holder 14a, b thus in the direction of the arrow be pressed down. From the structural arrangement shown in Fig. 1 it is clear that the height adjustment of the sole holder does not affect the release spring 4 and thus the release behavior of the toe piece or only slightly. Likewise, the setting of the trigger spring and the display of the same remain untouched.

Bei der in Figur 11 gezeigten Ausführungsform des Vorderbackens ist zur Erzeugung der Federkraft eine Blattfeder 43 vorgesehen, welche an einer Führung 44 des Gehäuseunterteils 3 abgestützt ist und an einem weiteren Anschlag 45 des Gehäuseoberteils wirkt. In diesem Fall wirkt die Höheneinstellung der Sohlenhalter völlig unabhängig von der Auslösefeder, welche in diesem Ausführungsbeispiel in Form zweier Federn 104, 204 realisiert ist.In the embodiment of the front jaw shown in FIG. 11, a leaf spring 43 is provided to generate the spring force, which is supported on a guide 44 of the lower housing part 3 and acts on a further stop 45 of the upper housing part. In this case, the height adjustment of the sole holder acts completely independently of the release spring, which is realized in the form of two springs 104, 204 in this exemplary embodiment.

Abschließend soll hier noch der in Figur 12 dargestellte Zusammenbau eines erfindungsgemäßen Vorderbackens näher erläutert werden. Nachdem der Gehäuseoberteil 2 vollständig zusammengebaut ist, d.h. mit der Auslösefeder 4, den Sohlenhaltern 14a, b, u.s.w. versehen wurde, wird dieser Gehäuseoberteil 2, wie in Fig. 12a zu sehen ist, unter einem Winkel von etwa 30° auf den Gehäuseunterteil aufgesetzt, sodaß die Lagerflächen 25a, b auf den Lagerköpfen 18a, b aufliegen. Sodann kann der Gehäuseoberteil 2 in Richtung Gehäuseunterteil geschwenkt werden, wobei die Haken 28a, b des Hakenelementes 27, wie in Fig. 12b zu sehen ist, unter die Vorsprünge 20a, b in das Einhakelement 19 eingreifen und somit eine vollständige Gelenksverbindung zwischen Gehäuseober- und Gehäuseunterteil herstellen. Abschließend wird das Verriegelungsstück 15 von unten in die Ausnehmung 16 des Gehäuseunterteils eingefügt und horizontal nach hinten geschoben, bis die Rastnase 27 in die erste 211 der V-förmigen Ausnehmungen 211, 212, 213, 214 einrastet. In dieser Stellung wirkt die am höchsten liegende Anschlagfläche 26a1, b1 mit dem Anschlag 29a, b des Gehäuseoberteils zusammen. Dadurch wird bei dem Zusammenbau des Vorderbackens ein maximaler Verschwenkwinkel des Gehäuseoberteils und somit eine maximale Höhenanpassung der Sohlenhalter voreingestellt. Bei der in Figur 1 gezeigten Ausführungsform mit dem Federhebel 8 wirkt dieser mit seinen seitlichen Vorsprüngen 42a, 42b an der Gleitführung 35 des Verriegelungsstückes 15, wodurch gleichzeitig mit dem Einbau dieses Verriegelungsstückes die federnde Verbindung zwischen Gehäuseober- und Gehäuseunterteil hergestellt wird. Bei der In Fig. 11 gezeigten Ausführungsform mit der Blattfeder 43 wird diese Feder ebenso gleichzeitig mit dem Verriegelungsstück 115 eingebaut und bei horizontalem Verschleben dieses Verriegelungsstückes an der Führung 44 des Gehäuseunterteils gehalten, sodaß sie an dem Anschlag 45 des Gehäuseoberteils wirkt.Finally, the assembly of a toe piece according to the invention shown in FIG. 12 will be explained in more detail here. After the upper housing part 2 has been completely assembled, ie provided with the release spring 4, the sole holders 14a, b, etc., this upper housing part 2, as can be seen in FIG. 12a, is placed on the lower housing part at an angle of approximately 30 °, so that the bearing surfaces 25a, b rest on the bearing heads 18a, b. Then the upper housing part 2 can be pivoted in the direction of the lower housing part, the hooks 28a, b of the hook element 27, as can be seen in FIG. 12b, engage under the projections 20a, b in the hooking element 19 and thus a complete articulated connection between the upper and lower housing elements Manufacture lower part of housing. Finally, the locking piece 15 is inserted from below into the recess 16 of the lower housing part and pushed horizontally backwards until the latch 27 engages in the first 21 1 of the V-shaped recesses 21 1 , 21 2 , 21 3 , 21 4 . In this position, the highest-lying stop surface 26a 1 , b 1 interacts with the stop 29a, b of the upper housing part. As a result, a maximum pivoting angle of the upper housing part and thus a maximum height adjustment of the sole holder is preset when the front jaw is assembled. In the embodiment shown in FIG. 1 with the spring lever 8, this acts with its lateral projections 42a, 42b on the slide guide 35 of the locking piece 15, whereby the resilient connection between the upper and lower housing parts is produced simultaneously with the installation of this locking piece. In the embodiment shown in FIG. 11 with the leaf spring 43, this spring is also installed simultaneously with the locking piece 115 and is held on the guide 44 of the lower housing part when this locking piece is worn horizontally, so that it acts on the stop 45 of the upper housing part.

In diesem Zustand wird der Vorderbacken der Skibindung nun auf dem Ski befestigt. Das geschieht dadurch, daß der Gehäuseunterteil 3, vorzugsweise mittels Schrauben an dem Ski befestigt wird, wodurch der Gehäuseoberteil in dem vorgegebenen Bereich gegen Federkraft verschwenkbar bleibt. Bei einer hier nicht gezeigten, jedoch im Verleihbetrieb vorzugsweise eingesetzten Ausführungsform des Vorderbackens, bei welcher das Verriegelungsstück eine einzige Anschlagfläche aufweist, ist keine weitere Einstellung des Vorderbackens in bezug auf die Sohlenhalter nötig. Bei den Vorderbacken mit Verriegelungsstücken gemäß der Figuren 7 bis 10, wird der Skischuh in die montierte Skibindung eingesetzt, wobei sich die Sohlenhalter bzw. der Gehäuseoberteil entsprechend der Schuhsohlenhohe gegen Federkraft nach oben bewegen. Das Verriegelungsstück 15, 115 wird nun bei eingesetztem Skischuh horizontal so weit wie möglich nach hinten in Richtung Skischuh verschoben, sodaß sich eine geeignete der Anschlagflächen 32a1, 32b1, 32a2, 32b2, 32a3, 32b3, 32a4, 32b4 direkt über dem Anschlag 29 befindet. Diese Anschlagfläche ist jene, die bei der durch den Skischuh vorgegebenen Stellung der Sohlenhalter gerade noch über dem Anschlag 29 liegt, wobei die Stellung des Verriegelungsstückes 15, 115 eine solche ist, bei welcher die Rastnase 27, 127 dieses Verriegelungsstückes in einer der V-förmigen Ausnehmungen 211, 212, 213, 214 eingerastet ist. Dadurch wird der Verschwenkbereich des Gehäuseoberteils 2 bezüglich des Gehäuseunterteils 3 auf ein Maß reduziert, das für die Sohle dieses Skischuhes tatsächlich erforderlich ist. Dadurch wird die Stabilität des Skischuhes in dem Vorderbacken erheblich erhöht. Der Vorteil dieser zusätzlichen Begrenzung macht sich auch im Rückwärtsauslöseverhalten der Skibindung bemerkbar. Wenn die Sohlenhalter bei einem Rückwärts- oder Rückwärtsdrehsturz nach oben belastet werden, wird zunächst der Gehäuseoberteil nach oben geschwenkt, bis der Anschlag 29a, b an der entsprechenden Anschlagfläche 32a1, 32b1, 32a2, 32b2, 32a3, 32b3, 32a4, 32b4 des Verriegelungsstückes 15, 115 anliegt. Danach wird erst der eigentliche Rückwärtsauslosemechanismus in Gang gesetzt, bei welchem der Lagerbolzen 13 für die Sohlenhalter 14a, b aus seiner Vertikallage ausgeschwenkt wird, sodaß sein unteres Ende entlang der in dem Führungsblock 30 eingelassenen Führungsfläche nach hinten bewegt wird und somit über das Zugstück 11 an der Auslösefeder 4 wirkt. Für eine Rückwärtsauslosung muß die auf die Sohlenhalter 14a, b nach oben wirkende Kraft groß genug sein, um die Sohlenhalter soweit zu verschwenken, daß der Skischuh nach oben aus dem Vorderbacken herausgleitet. Die konische Ausweitung der Führungsfläche für den Lagerbolzen ermöglicht insbesondere bei Rückwärtsdrehstürzen durch Ausschwenken des Lagerbolzens 13 aus seiner Mittellage eine Diagonalauslösung des Vorderbackens, bei welcher der Skischuh schräg nach oben freigegeben wird.In this state, the front jaw of the ski binding is now attached to the ski. This is done by attaching the lower housing part 3, preferably by means of screws, to the ski, as a result of which the upper housing part remains pivotable against spring force in the predetermined area. In an embodiment of the toe piece, not shown here, but preferably used in the rental business, in which the locking piece has a single stop surface, no further adjustment of the toe piece with respect to the sole holder is necessary. In the toe pieces with locking pieces according to FIGS. 7 to 10, the ski boot is inserted into the assembled ski binding, the sole holder or the upper part of the housing moving upwards against spring force in accordance with the height of the shoe sole. When the ski boot is inserted, the locking piece 15, 115 is now displaced horizontally as far back as possible in the direction of the ski boot, so that a suitable stop surface 32a 1 , 32b 1 , 32a 2 , 32b 2 , 32a 3 , 32b 3 , 32a 4 , 32b 4 is located directly above the stop 29. This stop surface is that which is just above the stop 29 in the position of the sole holder predetermined by the ski boot, the position of the locking piece 15, 115 being one in which the latching nose 27, 127 of this locking piece in one of the V-shaped Recesses 21 1 , 21 2 , 21 3 , 21 4 is engaged. As a result, the pivoting range of the upper housing part 2 with respect to the lower housing part 3 is reduced to a dimension that is actually required for the sole of this ski boot. This significantly increases the stability of the ski boot in the toe. The advantage of this additional limitation is also noticeable in the backward release behavior of the ski binding. If the sole holder is loaded upwards in the event of a backward or reverse turn, the upper part of the housing is first pivoted up until the stop 29a, b on the corresponding stop surface 32a 1 , 32b 1 , 32a 2 , 32b 2 , 32a 3 , 32b 3 , 32a 4 , 32b 4 of the locking piece 15, 115 abuts. Then the actual backward release mechanism is started, in which the bearing pin 13 for the sole holders 14a, b is pivoted out of its vertical position, so that its lower end is moved backwards along the guide surface embedded in the guide block 30 and thus via the tension piece 11 the trigger spring 4 acts. For a backward draw, the force acting upwards on the sole holders 14a, b must be large enough to pivot the sole holders so far that the ski boot slides upward out of the toe piece. The conical widening of the guide surface for the bearing pin enables a diagonal release of the front jaw, in which the ski boot is released at an angle upwards, in particular in the event of a backward rotation by pivoting the bearing pin 13 out of its central position.
