Description

Die Erfindung betrifft eine Skibindung-Skischuh-Kombination für einen Langlauf- oder Tourenski nach dem Oberbegriff des Anspruches 1.The invention relates to a ski binding-ski boot combination for a cross-country or touring ski according to the preamble of claim 1.

Eine Kombination der eingangs genannten Art ist beispielsweise in der DE-A1-30 02 874 (Fig. 29, 30) beschrieben. Bei dieser bekannten Lösung nimmt das Halteelement ein Einhakelement des Skischuhes auf, welches sich von der Skischuhspitze etwa horizontal nach vorne erstreckt, starr mit dem vorderen Skischuhende verbunden ist und einen quer zur Längsachse des Skischuhs verlaufenden Abschnitt aufweist, der im Abstand von der Skischuhspitze angeordnet ist, um auf das Halteelement aufgesetzt werden zu können. Das Verriegelungsglied der bekannten Lösung besteht aus einem in der Draufsicht betrachtet im allgemeinen U-förmigen Bügel, an welches ein Druckelement angelenkt ist. Die freien Endbereiche des U-förmigen Bügels greifen in das Halteelement ein und bilden somit eine zweite Schwenkachse für das Verriegelungsglied. Diese Ausgestaltung-bedeutet, daß zur Fixierung der Lage des Skischuhes an der Skibindung das Verriegelungsglied immer händisch betätigt werden muß, so daß kein automatisches Einsteigen (step-in) gegeben ist. Ein weiterer Nachteil der bekannten Lösung besteht darin, daß zufolge der Ausbildung des Verriegelungsgliedes als Kniehebel durch wiederholte Betätigungen zwischen den einzelnen Bauelementen dieser Verriegelungsvorrichtung Lockerungen entstehen können, wobei dann die Bedingung, jegliche Relativbewegung zwischen dem Halteelement und dem Einhakelement auszuschließen, nicht mit Sicherheit gewährleistet wird.A combination of the type mentioned at the outset is described, for example, in DE-A1-30 02 874 (FIGS. 29, 30). In this known solution, the holding element receives a hooking element of the ski shoe, which extends approximately horizontally forwards from the tip of the ski shoe, is rigidly connected to the front end of the ski shoe and has a section which runs transversely to the longitudinal axis of the ski shoe and is arranged at a distance from the tip of the ski shoe to be able to be placed on the holding element. The locking member of the known solution consists of a generally U-shaped bracket when viewed in plan view, to which a pressure element is articulated. The free end regions of the U-shaped bracket engage in the holding element and thus form a second pivot axis for the locking member. This configuration means that the locking member must always be operated manually to fix the position of the ski boot to the ski binding, so that there is no automatic step-in entry. Another disadvantage of the known solution is that, owing to the design of the locking member as a toggle lever, loosening can occur due to repeated actuations between the individual components of this locking device, in which case the condition of excluding any relative movement between the holding element and the hooking element is not guaranteed with certainty .

Aus der DE-A1-31 51 566 ist zwar eine Lösung bekannt, die eine Weiterentwicklung des Gegenstandes der DE-A1-3002874 insoferne zum Gegenstand hat, als bei dieser ein automatisches Einsteigen (step-in) verwirklicht ist, weist jedoch die vorangehend in Verbindung mit der in der DE-Al-30 02 874 beschriebenen Lösung angeführten weiteren Nachteile gleichfalls auf.A solution is known from DE-A1-31 51 566, which has the object of further developing the subject matter of DE-A1-3002874 insofar as an automatic step-in is realized in this, but has the above in Connection with the solution described in DE-Al-30 02 874 also has other disadvantages.

In der DE-A2-26 22 966 wurde zum Schutz das Einbetten einer Achse in die nach vorne gezogene Sohle eines Langlaufskischuhes sowie einer mit diesem mit Wirkverbindung tretenden Skibindung beansprucht. Dabei wird die Querachse des Skischuhes in dessen in die Skibindung eingesetztem Zustand von den beiden hakenförmigen Halteelementen der Bindung umgriffen. Allerdings dürfte diese Lösung für sich schon aus früheren Veröffentlichungen bekannt sein, da ein Patent auf diese Anmeldung (am 11.3.1981) rechtswirksam versagt worden ist.In DE-A2-26 22 966, the embedding of an axle in the forward-pulled sole of a cross-country ski boot and a ski binding that is operatively connected to it were claimed for protection. The cross axis of the ski boot is encompassed by the two hook-shaped holding elements of the binding in its state inserted into the ski binding. However, this solution should be known from previous publications, since a patent for this application (on March 11, 1981) has been legally refused.

In der EP-A1 88673 wird eine weitere Skibindung der eingangs genannten Art beschrieben. Bei dieser bekannten Lösung weist das Halteelement zwei Fortsätze auf, in welche entsprechend ausgestaltete Schlitze des Skischuhs von oben her einführbar sind. Dabei wird während eines Einstiegsvorganges das federbelastete Verriegelungsglied vorerst verschwenkt und bei voll eingesetztem Skischuh durch die Feder in die Raststellung gebracht. Die eben erwähnte Feder entspricht der in der gegenständlichen Anmeldung als zweite Feder bezeichneten Feder. Die Feder nach dem Stand der Technik liegt nachteiligerweise zwischen dem Tragkörper und dem Verriegelungsglied, wodurch eine stärkere Feder vorgesehen sein muß. Des weiteren wird ein elastischer Bauteil verwendet, der das Halteelement nicht dauernd unterstützt, sondern nur während eines Verschwenkvorganges, nach einem bestimmten Verschwenkwinkel, von der aus Halteelement und Verriegelungsglied bestehenden Einheit beaufschlagt wird. Durch diese diskontinuierliche Beaufschlagung beim Langlaufen können ruckartige Belastungen auftreten, die den Skiläufer unangenehm beeinträchtigen können.Another ski binding of the type mentioned at the outset is described in EP-A1 88673. In this known solution, the holding element has two extensions into which appropriately designed slots of the ski boot can be inserted from above. The spring-loaded locking member is initially pivoted during an entry process and brought into the latched position by the spring when the ski boot is fully inserted. The spring just mentioned corresponds to the spring referred to in the present application as the second spring. The spring according to the prior art is disadvantageously between the support body and the locking member, whereby a stronger spring must be provided. Furthermore, an elastic component is used, which does not continuously support the holding element, but rather only during a pivoting process, after a certain pivoting angle, from which the unit consisting of the holding element and the locking member acts. This discontinuous exposure to cross-country skiing can cause jerky loads, which can have an uncomfortable effect on the skier.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, die bekannte Lösung sowohl im Aufbau als auch in der Wirkung zu verbessern. Des weiteren sollen unerwünschte, systembedingte Lockerungen bzw. Ausleierungen vermieden werden und zusätzlich soll der Komfort durch ein automatisches Einsteigen (step-in) verbessert werden.The object of the present invention is to improve the known solution both in structure and in effect. Furthermore, undesired, system-related loosening or wear-out should be avoided and comfort should also be improved by an automatic step-in.

Gelöst wird die gestellte Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1.The object is achieved according to the invention by the characterizing features of claim 1.

Durch die angeführten Merkmale werden sämtliche gestellte Aufgaben erfüllt. Die Bindung baut kompakt, ermöglicht ein automatisches Einsteigen (step-in) und es können auch keine Verschleißerscheinungen auftreten, weil kein Kniehebel vorhanden ist, bei dessen Betätigung eine Totpunktlage überwunden werden müßte. Weiters wird eine besonders günstige Anordnung der zweiten Feder erzielt.Due to the listed features, all tasks are fulfilled. The binding is compact, enables an automatic boarding (step-in) and there are no signs of wear and tear because there is no toggle lever which, when actuated, would have to overcome a dead center position. Furthermore, a particularly favorable arrangement of the second spring is achieved.

Eine bevorzugte Ausführungsform der Erfindung besteht darin, daß die das Halteelement beaufschlagende erste Feder als eine Blattfeder oder ein Blattfederpaket ausgebildet ist, dessen eines Ende gemeinsam mit dem Grundkörper des Halteelementes auf dem Ski festgeschraubt ist.A preferred embodiment of the invention is that the first spring acting on the holding element is designed as a leaf spring or a leaf spring assembly, one end of which is screwed together with the base body of the holding element onto the ski.

Ein besonders kompakter Aufbau der Skibindung ist erfindungsgemäß dadurch gewährleistet, daß das Halteelement, im Aufriß betrachtet, etwa L-förmig ausgebildet und mit dem gleichfalls etwa L-förmig ausgebildeten Verriegelungsglied gemeinsam gegen die Kraft der ersten Feder verschwenkbar ist.A particularly compact construction of the ski binding is ensured according to the invention in that the holding element, viewed in elevation, is approximately L-shaped and can be pivoted together with the likewise approximately L-shaped locking member against the force of the first spring.

Zum leichteren Ein- und Aussteigen mit dem Skischuh ist erfindungsgemäß vorgesehen, daß im horizontalen Abschnitt des L-förmigen Halteelementes ein Ausschnitt vorgesehen ist, welcher in ihrem oberen Bereich durch sich trichterförmig erweiternde Schrägflächen begrenzt ist.To make it easier to get on and off with the ski boot, the invention provides that a cutout is provided in the horizontal section of the L-shaped holding element, which is delimited in its upper area by funnel-shaped inclined surfaces.

Ein anderer Erfindungsgedanke besteht darin, daß die zweite Feder mit ihrem einen Endbereich in der Aussparung des sich vertikal erstreckenden Abschnitt des L-förmigen Halteelementes und mit ihrem anderen Endbereich in der Aussparung des sich vertikal erstreckenden Abschnitt des L-förmigen Verriegelungsgliedes angeordnet ist. Auf diese Weise werden die einander gegenüberliegenden Bereiche des Halteelementes und des Verriegelungsgliedes zur Aufnahme der sie beaufschlagenden zweiten Feder verwendet.Another inventive concept is that the second spring with one end portion in the recess of the vertically extending portion of the L-shaped holding element and with its other end portion in the recess of the vertically extending portion of the L-shaped locking member is arranged. In this way, the mutually opposite regions of the holding element and the locking member are used to receive the second spring acting on them.

Die Schwenkbewegung des Verriegelungsgliedes wird in einfacher Weise erfindungsgemäß dadurch begrenzt, daß der Grundkörper einen nach oben ragenden Steg aufweist, dessen freier Endbereich mit einer Schrägfläche abgeschlossen ist, der bzw. die einen Anschlag für das Verriegelungsglied bildet.The pivoting movement of the locking member is limited in a simple manner according to the invention in that the base body has an upwardly projecting web, the free end area of which is closed with an inclined surface which forms a stop for the locking member.

Dieser Erfindungsgedanke wird noch dadurch begünstigt, daß das Verriegelungsglied in seinem vorderen Bereich eine Schrägfläche aufweist, welche parallel zur Schrägfläche des Steges des Grundkörpers verläuft.This inventive concept is further favored in that the locking member has an inclined surface in its front region, which runs parallel to the inclined surface of the web of the base body.

Eine besonders vorteilhafte und sichere Halterung des eingesetzten Skischuhes wird erfindungsgemäß dadurch erreicht, daß. das Verriegelungsglied an ihrem hinteren Endbereich eine nach hinten, zum einsetzenden Skischuh hin ragenden Ansatz aufweist, dessen Endbereich mit einer Schrägfläche abgeschlossen ist, und daß der Anschlußbereich des Skischuhes eine Sperre aufweist, welche, beim eingesetztem Skischuh in die Bindung, vom Ansatz übergriffen ist.A particularly advantageous and secure mounting of the ski boot used is achieved according to the invention in that. the locking member has at its rear end region a rearward, projecting approach to the ski boot, the end region of which is closed with an inclined surface, and that the connection region of the ski shoe has a lock which, when the ski shoe is inserted into the binding, is overlapped by the approach.

Der der Bindung zugehörige Skischuh zeichnet sich erfindungsgemäß dadurch aus, daß der Skischuh an seinem Anschlußbereich zwei seitliche Stege aufweist, in welchen die Querachse des ' Skischuhs gelagert ist, und daß die Stützflächen der beiden Stege mit der Stützfläche vorzugsweise fluchtend verlaufen.The ski boot associated with the binding is distinguished according to the invention in that the ski boot has two lateral webs in its connection area, in which the transverse axis of the ski boot is mounted, and that the support surfaces of the two webs preferably run flush with the support surface.

Eine Weiterentwicklung des Erfindungsgedankens liegt darin, daß der Skischuh in seiner in die Bindung eingesetzten Lage mittels seiner Sperre und Querachse zwischen dem Ansatz des Verriegelungsgliedes und dem Ausschnitt des Halteelementes eingespannt ist und sich mit seiner Stützfläche am Abstützbereich des Verriegelungsgliedes abstützt.A further development of the idea of the invention is that the ski boot is clamped in its position in the binding by means of its lock and transverse axis between the attachment of the locking member and the cutout of the holding element and is supported with its support surface on the support area of the locking member.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun an Hand der Zeichnung, die ein Ausführungsbeispiel darstellt, näher beschrieben. Hiebei zeigen : die Fig. 1 einen Aufriß der erfindungsgemäßen Bindung, Fig. 2 eine Draufsicht zu Fig. 1, Fig. 3 den Anschlußbereich eines Skischuhes zum Zusammenwirken mit der Skibindung im Aufriß, Fig. 4 eine Draufsicht zu Fig. 3 und Fig. 5 eine Vorderansicht des Skischuhes nach den Fig. 3 und 4.Further features, advantages and details of the invention will now be described in more detail with reference to the drawing, which represents an exemplary embodiment. 1 shows an elevation of the binding according to the invention, FIG. 2 shows a top view of FIG. 1, FIG. 3 shows the connection area of a ski boot for interacting with the ski binding in elevation, FIG. 4 shows a top view of FIGS. 3 and FIG. 5 shows a front view of the ski boot according to FIGS. 3 and 4.

Wie man es den Fig. 1 und 2 entnehmen kann, ist die in ihrer Gesamtheit mit 1 bezeichnete Skibindung auf der Oberseite eines Skis 2 mittels, in Fig. 1 nur angedeuteter, Schrauben 3 befestigt. Der auf der Oberseite des Skis 2 aufliegende Teil der Skibindung 1 ist ein Grundkörper 4, welcher eine Achse 5 trägt. An der Achse 5 sind ein Halteelement 6 und ein noch näher zu beschreibendes Verriegelungsglied 7 schwenkbar gelagert. Das Halteelement 6 weist, im Aufriß betrachtet. eine etwa L-förmige Gestalt auf. Dabei ist im horizontalen Abschnitt des L-s ein Auschnitt 6a vorgesehen, welcher in ihrem oberen Bereich durch sich trichterförmig erweiternde Schrägflächen 6b und 6c begrenzt ist. Auf die Wirkungsweise der Schrägflächen 6b, 6c wird später eingegangen werden. Im sich vertikal erstreckenden Abschnitt des L-s ist eine Aussparung 6d vorgesehen, in welcher der eine Endbereich einer Feder 8 sitzt. Die Feder 8 ist als eine Schraubendruckfeder ausgestaltet.As can be seen from FIGS. 1 and 2, the ski binding, designated in its entirety by 1, is fastened to the top of a ski 2 by means of screws 3, which are only indicated in FIG. 1. The part of the ski binding 1 resting on the top of the ski 2 is a base body 4, which carries an axis 5. On the axis 5, a holding element 6 and a locking member 7 to be described in more detail are pivotably mounted. The holding element 6 has, viewed in elevation. an approximately L-shaped shape. In this case, a cutout 6a is provided in the horizontal section of the L-s, which is delimited in its upper region by obliquely widening oblique surfaces 6b and 6c. The operation of the inclined surfaces 6b, 6c will be discussed later. In the vertically extending section of the L-s, a recess 6d is provided, in which one end region of a spring 8 is seated. The spring 8 is designed as a helical compression spring.

Das Verriegelungsglied 7 ist seinerseits ebenfalls etwa L-förmig gestaltet, jedoch mit dem Unterschied, daß der freie Endbereich des vertikalen Abschnittes des L-s von der Achse 5 durchsetzt ist und somit das L sozusagen auf dem Kopf steht. Dabei erstreckt sich der horizontale Abschnitt des L-s, bezogen auf die Achse 5, zum horizontalen Abschnitt des L-förmigen Halteelementes 6 spiegelbildgleich nach vorne.The locking member 7 in turn is also approximately L-shaped, but with the difference that the free end region of the vertical section of the L-s is penetrated by the axis 5 and thus the L is, so to speak, upside down. The horizontal section of the L-s, with respect to the axis 5, extends forward to the horizontal section of the L-shaped holding element 6 in a mirror image.

Der horizontale Abschnitt des Verriegelungsgliedes 7 weist im vorderen Bereich eine Schrägfläche 7a, eine Aufnahmestelle 7b zum Einsetzen des Spitzenbereiches eines Skistockes sowie an ihrem hinteren Bereich eine nach hinten, zum einzusetzenden Skischuh hin ragenden Ansatz 7c auf. Der Ansatz 7c dient als eine Sperrnase und ist hiefür an seinem unteren Endbereich mit einer Schrägfläche 7c, abgeschlossen. Die Schräge verläuft dabei unter einem spitzen Winkel, welcher in Richtung zum Schuhende hin geschlossen ist. Im vertikalen Abschnitt des Verriegelungsgliedes 7 ist eine Aussparung 7d vorgesehen, in welcher der andere Endbereich der Feder 8 sitzt.The horizontal section of the locking member 7 has an inclined surface 7a in the front area, a receiving point 7b for inserting the tip area of a ski pole and, at its rear area, an extension 7c projecting towards the ski boot to be used. The approach 7c serves as a locking lug and is closed at its lower end with an inclined surface 7c. The slope runs at an acute angle, which is closed towards the end of the shoe. In the vertical section of the locking member 7, a recess 7d is provided, in which the other end region of the spring 8 is seated.

Die jeweils eine Aussparung 6d bzw. 7d aufweisenden, sich vertikal erstreckenden Abschnitte des Halteelementes 6 bzw. des Verriegelungsgliedes 7 begrenzen einen Hohlraum, in dem die Feder 8 angeordnet ist.The vertically extending sections of the holding element 6 and of the locking member 7, each having a recess 6d and 7d, delimit a cavity in which the spring 8 is arranged.

Der Grundkörper 4 weist einen nach oben ragenden Steg 4a auf, dessen freier Endbereich mit einer Schrägfläche 4a, abgeschlossen ist, die parallel zur Schrägfläche 7a im vorderen Bereich des Verriegelungsgliedes 7 verläuft und in deren geöffneten Lage eine Art Anschlag bildet.The base body 4 has an upwardly projecting web 4a, the free end region of which is closed with an inclined surface 4a, which runs parallel to the inclined surface 7a in the front region of the locking member 7 and forms a kind of stop in its open position.

Zwischen der Oberseite des Skis 2 und der Unterseite des Grundkörpers 4 ist ein aus mehreren Blattfedern bestehendes Federpaket 9 vorgesehen, dessen anderer Endbereich an der Vorderseite des Halteelementes 6 abgestützt ist. Das Halteelement 6 und das Verriegelungsglied 7 können daher um die Achse 5 gemeinsam gegen die Kraft des Federpaketes 9 verschwenkt werden. Des weiteren kann das Verriegelungsglied 7 relativ zum Halteelement 6 gegen die Kraft der Schraubendruckfeder 8 zwecks Schließen und Öffnen der Bindung verschwenkt werden. Auf die Einzelheiten der Wirkungsweise der Skibindung 1 wird nach Beschreibung des Anschlußbereiches des einzusetzenden Skischuhes 11 näher eingegangen werden.Between the top of the ski 2 and the underside of the base body 4, a spring assembly 9 consisting of several leaf springs is provided, the other end region of which is supported on the front of the holding element 6. The holding element 6 and the locking member 7 can therefore be pivoted together about the axis 5 against the force of the spring assembly 9. Furthermore, the locking member 7 can be pivoted relative to the holding element 6 against the force of the helical compression spring 8 for the purpose of closing and opening the binding. The details of the mode of operation of the ski binding 1 will be discussed in more detail after the description of the connection area of the ski boot 11 to be used.

Von dem in seiner Gesamtheit mit 11 bezeichneten Skischuh ist in den Fig. 3 bis 5 lediglich der für die Erfindung wesentliche Anschlußbereich 12 dargestellt. Dabei ist erkennbar, daß der Skischuh 11 eine vordere Stützfläche 18 aufweist, die im wesentlichen vertikal zur Skischuhsohle 13 verläuft. Etwa in der Höhe der Skischuhsohle durchsetzt eine Querachse 14 den Anschlußbereich 12. Die Querachse 14 ist von zwei Stegen 15. 16 des Anschlußbereiches 12 des Skischuhes 11 gehalten. wobei im eingesetzten Zustand des Skischuhes 11 in die Skibindung 1 die Querachse 14 im Ausschnitt 6a des Halteelementes 6 liegt.Of the ski boot designated 11 in its entirety, only the connection area 12 essential for the invention is shown in FIGS. 3 to 5. It can be seen that the ski boot 11 has a front support surface 18 which is substantially vertical to the ski boot sole 13 runs. A transverse axis 14 passes through the connection area 12 approximately at the height of the ski boot sole. The transverse axis 14 is held by two webs 15, 16 of the connection area 12 of the ski shoe 11. the transverse axis 14 being in the cutout 6a of the holding element 6 in the inserted state of the ski boot 11 in the ski binding 1.

Die Wirkungsweise der erfindungsgemäßen Skibindung 1 im Zusammenwirken mit dem ebenfalls erfindungsgemäßen Skischuh 11 ist nun wie folgt.The mode of operation of the ski binding 1 according to the invention in cooperation with the ski boot 11 also according to the invention is now as follows.

Beim Einsteigen mit dem Skischuh 11 in die Skibindung 1 wird die Querachse 14 des Skischuhs 11 auf die Schrägfläche 6b des Halteelementes 6 gesetzt, daraufhin wird der Skischuh 11 nach unten gedrückt, wobei das Verriegelungsglied 7 durch die Stützfläche 18 des Skischuhs 11, gegen die Wirkung der Feder 8, nach vor geschwenkt wird. In der unteren Endlage, wenn die Querachse 14 im Ausschnitt 6a des Halteelementes 6 zum Liegen kommt, schwenkt das Verriegelungsglied 7 durch die Feder 8 beaufschlagt, im Uhrzeigersinn, wobei die Schrägfläche 7ci des Ansatzes 7c oberhalb der Sperre 17 des Anschlußbereiches 12 des Skischuhs 11 zum Liegen kommt. Da am Abstützbereich 7e des Verriegelungsgliedes 7 der Skischuh 11 mit seiner Stützfläche 18 anliegt, ist der Skischuh 11 zwischen dem Halteelement 6 und dem Verriegelungsglied 7 sicher gehalten, wobei Halteelement 6 und Verriegelungsglied 7 nunmehr als eine Einheit funktionieren.When getting into the ski binding 1 with the ski boot 11, the transverse axis 14 of the ski boot 11 is placed on the inclined surface 6b of the holding element 6, then the ski boot 11 is pressed down, the locking member 7 being supported by the support surface 18 of the ski boot 11 against the action the spring 8, is pivoted before. In the lower end position, when the transverse axis 14 comes to rest in the cutout 6a of the holding element 6, the locking member 7 pivots by the spring 8, clockwise, the inclined surface 7ci of the extension 7c above the lock 17 of the connection area 12 of the ski boot 11 to Lying comes. Since the ski boot 11 rests with its support surface 18 on the support region 7e of the locking member 7, the ski boot 11 is securely held between the holding element 6 and the locking member 7, the holding element 6 and locking member 7 now functioning as one unit.

Während der Betätigung des Skischuhes 11 durch den. Skifahrer, beispielsweise während eines Langlaufschrittes, wird die vorerwähnte Einheit gegen die Kraft des Federpaketes 9 verschwenkt, so daß in der darauffolgenden Phase des Langlaufschrittes, nämlich wenn die Skischuhsohle 13 wieder auf der Oberseite des Skis 2 aufliegt, die Rückführung durch das Federpaket 9 erleichtert wird.During the operation of the ski boot 11 by the. Skiers, for example during a cross-country skiing step, the aforementioned unit is pivoted against the force of the spring assembly 9, so that the return by the spring assembly 9 is facilitated in the subsequent phase of the cross-country skiing step, namely when the ski shoe sole 13 rests on the upper side of the ski 2 .

Will der Skifahrer aus der Skibindung 1 aussteigen, so genügt es, wenn er die Spitze seines Skistockes in die zu diesem Zweck vorgesehene Aufnahmestelle 7b des Verriegelungsgliedes 7 setzt und letzteres gegen die Kraft der Schraubendruckfeder 8 nach vorne verschwenkt. Nachdem der Ansatz 7c des Verriegelungsgliedes 7 die Stützfläche 18 des vorderen Anschlußbereiches 12 des Skischuhes 11 verlassen hat, kann der Skischuh 11 durch Hochheben aus der Skibindung 1 entfernt werden.If the skier wants to get out of the ski binding 1, it is sufficient if he places the tip of his ski pole in the receiving point 7b of the locking member 7 provided for this purpose and pivots the latter forward against the force of the helical compression spring 8. After the shoulder 7c of the locking member 7 has left the support surface 18 of the front connection area 12 of the ski boot 11, the ski boot 11 can be removed from the ski binding 1 by lifting it up.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel eingeschränkt. Es sind weitere Abwandlungen denkbar, ohne den Rahmen des Schutzumfanges zu verlassen. So kann insbesondere die Ausgestaltung der beiden Federn anders sein. Anstelle der Schraubendruckfeder kann beispielsweise eine Tellerfeder Verwendung finden ; das aus Blattfedern bestehende Federpaket kann durch eine oder durch mehrere Schraubenfedern oder auch Tellerfedern ersetzt werden, welche sich mit ihrem anderen Ende am Steg des Halteelementes abstützen.The invention is not restricted to the exemplary embodiment shown. Further modifications are conceivable without leaving the scope of the scope of protection. In particular, the design of the two springs can be different. Instead of the helical compression spring, for example, a plate spring can be used; the spring assembly consisting of leaf springs can be replaced by one or more coil springs or also plate springs, which are supported with their other end on the web of the holding element.

Aber auch der Anschlußbereich des Skischuhes kann anders gestaltet sein, beispielsweise kann die Querachse den Anschlußbereich seitlich überragen, in welchem Fall der den Ausschnitt aufweisende Bereich des Halteelementes von zwei Stegen gebildet wird, an welchen die Querachse mit ihren beiden Endbereichen aufliegt.But also the connection area of the ski boot can be designed differently, for example the transverse axis can protrude laterally beyond the connection area, in which case the area of the holding element which has the cutout is formed by two webs on which the transverse axis rests with its two end areas.
