Abstract

The safety ski binding has a sole plate (5) which is mounted swivellably on a pivot (2a), which is fixed to the ski, and bears at its rear end a heel hold-down (7). A sole hold-down (13), which is swivellable on the bearing block (8) of the safety ski binding, is held in the travelling position by two coupled pairs of straps (14; 17), linked to the bearing block (8), via a first compression spring (9). A control lever (25), linked to the bearing block (8), engages via a roller (26) in a horizontal control cam (4b), which is fixed to the ski, and holds the sole plate (5) in the travelling position by means of a second compression spring (10). The first pair of straps is linked to the bearing block (8) as a catch link (14) and the second pair of straps as a rocker (17), the catch link (14) and the rocker (17) being coupled to each other by a coupling part (19), which is guided by means of a slide bolt (21) in an elongate hole (14d) of the rocker (14). Linked to the slide bolt (21) is a spring-loaded blocking lever (22) which grips below the swivel axle (12) in the travelling position and brings about the rigid coupling between the catch link (14) and the rocker (17). The control lever (25) is loaded by the second compression spring (10) via a carrier (27a), said carrier (27a) being intended for engagement on the blocking lever (22) during horizontal swivelling of the sole plate (5). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Sicherheitsskibindung, insbesondere Fersenhalter, nach dem Oberbegriff des Patentanspruches 1.The invention relates to a safety ski binding, in particular heel holder, according to the preamble of claim 1.

Ein Fersenhalter der eingangs genannten Art ist in der DE-OS 31 0 010 beschrieben. Bei dieser Ausführung befinden sich beide Laschen auf einer lagerbockfesten Achse, wobei die Kopplung der Laschen durch eine Knie­hebel geschieht. Der Steuerhebel, der die Hoizontalverschwenkung der Sohlenplatte überwacht, wirkt ab einem gewissen Schwenkwinkel direkt auf den Kniehebel ein und löst die Kopplung der beiden Laschen, worauf der Sohlenhalter von der ersten Druckfeder unbelastet hochschwenkt. Des wei­teren ist der Auslösehebel am Lagerbock angelenkt und greift bei Betätigung auch am Kniehebel an. Bei dieser Ausführung handelt es sich um einen Fersenhalter mit Vertikal- und Horizontalauslösung, die sich gegenseitig beeinflussen, da sich sowohl bei Vertikal- als auch bei Horizontalver­schwenkung die relative Lage von Steuerhebel und Kniehebel derart ver­ändert, daß sich diese einander annähern. D.h., daß eine Verschwenkung in einer Richtung einer geringere Verschwenkung in der dazu senkrechten Rich­tung benötigt, um zu einer Auslösung zu führen. Es handelt sich dabei um eine scheinbare Diagonalauslösung, die jedoch den Nachteil hat, daß Wege ver­kürzt werden, und daß dadurch die Elastizität der Bindung in beiden Rich­tungen vermindert wird. Ein weiterer Nachteil dieses Fersenhalters ist, daß sich die erste Druckfeder beim Hochschwenken des Sohlenhalters völlig entspannt, was beim Wiedereinstieg in die Bindung zu einer hohen Einstiegs­kraft führt.A heel holder of the type mentioned is described in DE-OS 31 0 010. In this version, both brackets are located on an axle that is fixed to the bearing block, the brackets being coupled by a toggle lever. The control lever, which monitors the horizontal swiveling of the sole plate, acts directly on the knee lever from a certain swivel angle and releases the coupling of the two tabs, whereupon the sole holder swings up unloaded by the first compression spring. Furthermore, the release lever is articulated on the bearing block and also acts on the toggle lever when actuated. This version is a heel holder with vertical and horizontal release, which mutually influence one another, since the relative position of the control lever and toggle lever changes in both vertical and horizontal pivoting in such a way that they approach each other. That is, pivoting in one direction requires less pivoting in the direction perpendicular to it to result in tripping. It is an apparent diagonal release, but has the disadvantage that distances are shortened and that this reduces the elasticity of the binding in both directions. Another disadvantage of this heel holder is that the first compression spring relaxes completely when the sole holder is swung up, which leads to a high entry force when the binding is re-entered.

Die Erfindung hat sich die Aufgabe gestellt, eine Sicherheitsskibindung der eingangs genannten Art zu schaffen, die einen Fersenhalter mit Vertikal- und Horizontalauslösung aufweist, ohne die Nachteile der oben angeführten Lösungen zu besitzen.The invention has for its object to provide a safety ski binding of the type mentioned, which has a heel holder with vertical and horizontal release, without having the disadvantages of the above solutions.

Erreicht wird das gesetzte Ziel erfindungsgemäß durch die im Anspruch 1 enthaltenen kennzeichnenden Merkmale.The set goal is achieved according to the invention by the characterizing features contained in claim 1.

Durch die erfindungsgemäßen Maßnahmen wird die Steuerung für die Aus­lösung in der vertikalen und in der horizontalen Ebene voneinander getrennt, wodurch der Fersenhalter in beiden Richtungen eine größere Elastizität aufweist. Außerdem haben die beiden Druckfedern getrennte Einstell­schrauben, was eine bessere Abstimmung der Federkraft gewährleistet. Aufgrund der Ausgestaltung und des Zusammenwirkens von Rastschwinge, Schwinge, Sperrhebel und Mitnehmer handelt es sich um ein vorgespanntes System, d.h. daß sich die erste Druckfeder bei der Öffnung des Fersenhalters nicht voll entspannt, wodurch die zum Einsteigen erforderliche Kraft in den geöffneten Fersenhalter erheblich reduziert wird.The measures according to the invention separate the control for the release in the vertical and in the horizontal plane, as a result of which the heel holder has greater elasticity in both directions. In addition, the two compression springs have separate adjusting screws, which ensures better adjustment of the spring force. Due to the design and interaction of the locking arm, swing arm, locking lever and driver, it is a pre-tensioned system, i.e. that the first compression spring does not fully relax when the heel holder is opened, which considerably reduces the force required to get into the open heel holder.

Die Merkmale des Anspruches 2 stellen eine vorteilhafte konstruktive Ausge­staltung der Schwinge dar.The features of claim 2 represent an advantageous structural design of the rocker.

Nach den Merkmalen des Anspruches 3 wird der Gleitbolzen in der unteren Position im Langloch gehalten und damit die starre Kopplung zwischen Rastschwinge und Schwinge bewirkt.According to the features of claim 3, the slide pin is held in the lower position in the elongated hole and thus causes the rigid coupling between the locking rocker and rocker.

Nach den Merkmalen des Anspruches 4 bewirkt die Feder, daß in Fahrt­stellung der Sperrhebel in der die Schwenkachse untergreifenden Lage ver­bleibt, und daß nach einer Horizontalauslösung, bei der die Kopplung zwischen Rastschwinge und Schwinge aufgehoben wird, die Regenerierung der Bindung erfolgt, indem der Gleitbolzen und damit der Sperrhebel wieder nach unten geführt und der Haken des Sperrhebels unter die Schwenkachse gedrückt wird.According to the features of claim 4, the spring causes that in the driving position of the locking lever remains in the position under the pivot axis, and that after a horizontal release, in which the coupling between the rocker arm and the rocker is released, the regeneration of the binding takes place by the sliding bolt and so that the locking lever is brought down again and the hook of the locking lever is pressed under the pivot axis.

Die Merkmale des Anspruches 5 bewirken, daß der Mitnehmer mit dem Haken des Sperrhebels zusammenwirkt, und daß sich eine gute Abstimmbarkeit des Schwenkwinkels, bei dem die Horizontalauslösung stattfindet, ergibt.The features of claim 5 cause that the driver cooperates with the hook of the locking lever, and that there is a good tunability of the pivot angle at which the horizontal release takes place.

Durch die Merkmale des Anspruches 6 wird der Sohlenhalter nach einer Horizontalöffnung, bei der Rastschwinge und Schwinge entkoppelt wurden, durch die Schließfeder geschlossen, um die Regenerierung des Fersenhalters durch die Feder einzuleiten.Due to the features of claim 6, the sole holder is closed by the closing spring after a horizontal opening, in which the locking rocker and the rocker have been decoupled, in order to initiate the regeneration of the heel holder by the spring.

Nach den Merkmalen des Anspruches 7 ist der obere Teil der Steuerkurve so ausgestaltet, daß sich die erste Druckfeder nur so weit entspannt, daß sie dabei eine Öffnungskraft für den Sohlenhalter entgegen der Kraft der Schließfeder liefert.According to the features of claim 7, the upper part of the control cam is designed so that the first compression spring relaxes only to such an extent that it provides an opening force for the sole holder against the force of the closing spring.

Die in den Fig.1 bis 8 dargestellte Sicherheitsskibindung ist eine komplette Skibindung mit einer Sohlenplatte. Nach Fig.8 ist auf der Oberseite eines Ski 1 mittels nicht dargestellter Schrauben eine dreigeteilte Grundplatte befestigt, deren mittlerer Teil 2 einen Drehzapfen 2a trägt, auf welchem die Sohlenplatte 5 der Bindung gelagert ist. Der vordere bzw.hintere Teil 3,4 der Grundplatte ist unterhalb dem vorderen bzw. hinteren Bereich der Sohlen­platte 5 befestigt. Vorderer und hinterer Teil 3,4 der Grundplatte tragen an der dem Drehzapfen 2a zugewandten Seite je eine Abkröpfung, die in eine entsprechende Führungsnut der Sohlenplatte 5 eingreift, welche ein Abheben der Sohlenplatte 5 verhindert und zu deren Führung dient. Aus Fig.1 sind die Abkröpfung 4a des hinteren Teiles 4 der Grundplatte und die Führungsnut 5a der Sohlenplatte 5 ersichtlich. Der hintere Teil 4 der Grundplatte trägt an seinem der Abkröpfung 4a abgewandten Bereich eine V-förmige Horizontal­ steuerkurve 4b. Die Sohlenplatte 5 trägt an ihrem vorderen Ende einen Vorderbacken 6 und an ihrem hinteren Ende einen Lagerbock 8, der Bestand­teil eines Fersenhalters 7 ist.The safety ski binding shown in FIGS. 1 to 8 is a complete ski binding with a sole plate. According to FIG. 8, a three-part base plate is fastened to the top of a ski 1 by means of screws (not shown), the central part 2 of which carries a pivot 2a on which the sole plate 5 of the binding is mounted. The front or rear part 3, 4 of the base plate is fastened below the front or rear area of the sole plate 5. The front and rear part 3, 4 of the base plate each have an offset on the side facing the pivot 2a, which engages in a corresponding guide groove in the sole plate 5, which prevents the sole plate 5 from lifting off and serves to guide it. The bend 4a of the rear part 4 of the base plate and the guide groove 5a of the sole plate 5 can be seen from FIG. The rear part 4 of the base plate has a V-shaped horizontal on its area facing away from the offset 4a control curve 4b. The sole plate 5 has a front jaw 6 at its front end and a bearing block 8 at its rear end, which is part of a heel holder 7.

In den Fig.1 bis 7 ist der Fersenhalter 7 der Sicherheitsskibindung dargestellt. Der Lagerbock 8 ist zugleich als Federgehäuse für zwei Druckfedern 9,10 ausgebildet. Der Lagerbock 8 trägt in seinem vorderen Teil zwei Achsen, nämlich in seinem oberen Bereich eine Querachse 11 und in seinem unteren Bereich eine zur Querachse 11 parallele Schwenkachse 12. An der Querachse 11 ist ein Sohlenhalter 13 und an der Schwenkachse 12 eine Rastschwinge 14 gelagert. Der Sohlenhalter 13, der an seinem vorderen Ende einen Sohlen­niederhalter 13a und einen Trissporn 13b trägt, weist im Inneren ein walzenförmiges Rastelement 13c, Führungsflächen 13d für einen Auslöse­hebel 15 und Schlitze zum Durchgriff für den Auslösehebel 15 auf. Die Rastschwinge 14, die aus einem ersten Laschenpaar gebildet ist, welches in seinem unteren Bereich an der Schwenkachse 12 angelenkt ist, trägt in ihrem oberen Bereich einen Bolzen 16, an dem der Auslösehebel 15 verschwenkbar gelagert ist. In ihrem dem Rastelement 13c des Sohlenhalters 13 zugewandten Bereich weist sie eine Steuerkurve 14a mit einem Auslösepunkt 14b auf.1 to 7 show the heel holder 7 of the safety ski binding. The bearing block 8 is also designed as a spring housing for two compression springs 9, 10. The bearing block 8 carries two axes in its front part, namely a transverse axis 11 in its upper region and a pivot axis 12 parallel to the transverse axis 11 in its lower region. A sole holder 13 is mounted on the transverse axis 11 and a latching rocker 14 is mounted on the pivot axis 12. The sole holder 13, which carries a sole hold-down device 13a and a tris spur 13b at its front end, has a roller-shaped latching element 13c, guide surfaces 13d for a release lever 15 and slots for reaching through for the release lever 15 on the inside. The locking rocker 14, which is formed from a first pair of tabs which is articulated in its lower region on the pivot axis 12, carries in its upper region a bolt 16 on which the release lever 15 is pivotably mounted. In its area facing the locking element 13c of the sole holder 13, it has a control cam 14a with a trigger point 14b.

An der Querachse 11 ist weiters eine Schwinge 17 angelenkt, die aus einem zweiten Laschenpaar gebildet ist. Die Schwinge 17 ist, in Seitenansicht betrachtet, etwa dreieckförmig gestaltet und weist eine Ausnehmung 17a auf, in die der Quersteg 18a eines ersten Schiebers 18 eingehängt ist, der durch die erste Druckfeder 9 belastet ist. Der Quersteg 18a ragt dabei über das Federwiderlager 18b des ersten Schiebers 18 hinaus. Die Schwinge 17 stützt sich an der Schwenkachse 12 ab.On the transverse axis 11 a rocker 17 is further articulated, which is formed from a second pair of tabs. When viewed in a side view, the rocker 17 is approximately triangular in shape and has a recess 17a, in which the crosspiece 18a of a first slide 18 is suspended, which is loaded by the first compression spring 9. The crosspiece 18a projects beyond the spring abutment 18b of the first slide 18. The rocker 17 is supported on the pivot axis 12.

Rastschwinge 14 und Schwinge 17 sind mit einem Kopplungsteil 19, bestehend aus einem dritten Laschenpaar, verbunden. Der Kopplungsteil 19 ist mittels eines Schwenkbolzens 20 mit der Schwinge 17 und mittels eines Gleitbolzens 21, der in einem Langloch 14d der Rastschwinge 14 gleitet, mit der Rastschwinge 14 verbunden. Am Gleitbolzen 21 ist ein einen Haken 22a aufweisender Sperrhebel 22 angelenkt, der durch eine am Gleitbolzen 21 befestigte Feder 23, die sich mit ihrem ersten 23a Schenkel von unten an der Querachse 11 abstützt, im Uhrzeigersinn beaufschlagt ist.Locking arm 14 and rocker 17 are connected to a coupling part 19 consisting of a third pair of straps. The coupling part 19 is connected to the rocker arm 17 by means of a pivot pin 20 and by means of a slide pin 21, which slides in an elongated hole 14d of the latch arm 14, to the latch arm 14. A locking lever 22, which has a hook 22a, is articulated on the sliding pin 21 and is acted upon in a clockwise direction by a spring 23 fastened to the sliding pin 21 and supported by its first 23a leg from below on the transverse axis 11.

An der Querachse 11 ist ferner eine Schließfeder 24 befestigt, die sich einerseits an einem Ansatz 13e des Sohlenhalters 13 und andererseits am Schwenkbolzen 20 abstützt.On the transverse axis 11, a closing spring 24 is also attached, which is supported on the one hand on a shoulder 13e of the sole holder 13 and on the other hand on the pivot pin 20.

Auf der Schwenkachse 12 ist weiters ein Steuerhebel 25 gelagert, der in seinem unteren Bereich eine auf einer Achse gelagerte Rolle 26 aufweist, welche Rolle 26 der V-förmigen Horizontalsteuerkurve 4b am hinteren Teil 4 der Grundplatte zugeordnet ist. Der Steuerhebel 25 wird mittels eines zweiten Schiebers 27, der einen nach oben gerichteten Mitnehmer 27a aufweist, von der zweiten Druckfeder 10 beaufschlagt.A control lever 25 is also mounted on the pivot axis 12 and has in its lower region a roller 26 mounted on an axis, which roller 26 is assigned to the V-shaped horizontal control curve 4b on the rear part 4 of the base plate. The control lever 25 is acted upon by the second compression spring 10 by means of a second slide 27, which has an upward driver 27a.

Erste und zweite Druckfeder 9,10 können mittels Einstellschrauben 28,29 vorgespannt werden, wobei die Einstellschrauben 28,29 im Lagerbock 8 drehbar, aber gegen axiale Verschiebung gesichert gelagert sind. Die Feder­teller 30,31 sind im Lagerbock 8 geführt und in bekannter Weise gegen ein Verdrehen gesichert.The first and second compression springs 9, 10 can be pretensioned by means of adjusting screws 28, 29, the adjusting screws 28, 29 being rotatably mounted in the bearing block 8, but secured against axial displacement. The spring plates 30, 31 are guided in the bearing block 8 and secured against rotation in a known manner.

Einzelheiten des Auslösehebels 15 können besonders gut der Fig.7 entnommen werden. Der Auslösehebel 15 ist in Vorderansicht etwa U-förmig mit zwei Schenkeln 15a ausgebildet. Er weist an jedem seiner Schenkel 15a zwei Fortsätze 15b,15c auf, die mit der jeweiligen Führungsfläche 13d des Sohlenhalters 13 zusammenwirken. Im geschlossenen Zustand der Bindung stützen sich die oberen wie auch die unteren Fortsätze 15b,15c an den Führungsflächen 13d des Sohlenhalters 13, die seitlich von der Längsmittel­ebene liegen, ab. In jedem der beiden Schenkel 15a des Auslösehebels 15 befindet sich im mittleren Bereich eine Freistellung 15d für die Quer­achse 11.Details of the release lever 15 can be seen particularly well in FIG. The release lever 15 is approximately U-shaped in front view with two legs 15a. It has two extensions 15b, 15c on each of its legs 15a, which cooperate with the respective guide surface 13d of the sole holder 13. In the closed state of the binding, the upper as well as the lower extensions 15b, 15c are supported on the guide surfaces 13d of the sole holder 13, which lie laterally from the longitudinal center plane. In each of the two legs 15a of the release lever 15 there is an exemption 15d for the transverse axis 11 in the central region.

In der in Fig.1 dargestellten Fahrtstellung wird der Sohlenhalter 13 von der ersten Druckfeder 9 festgehalten. Die zweite Druckfeder 10 sichert den Fersenhalter 7 gegen ein Verschwenken in der Horizontalebene. In der Fahrtstellung sind Rastschwinge 14 und Schwinge 17 starr über den Kopp­lungsteil 19 miteinander gekoppelt, da der Gleitbolzen 21 mittels des Sperrhebels 22, der an der Schwenkachse 12 verhakt ist, in seiner unteren Lage im Langloch 14d festgehalten wird.In the travel position shown in Figure 1, the sole holder 13 is held by the first compression spring 9. The second compression spring 10 secures the heel holder 7 against pivoting in the horizontal plane. In the driving position, the locking rocker 14 and rocker 17 are rigidly coupled to one another via the coupling part 19, since the slide pin 21 is held in its lower position in the elongated hole 14d by means of the locking lever 22, which is hooked on the pivot axis 12.

Bei einem Frontalsturz kommt es zu einer Vertikalverschwenkung des Sohlen­halters 13, wobei die Rastschwinge 14 vom Rastelement 13c des Sohlen­halters 13, das entlang der Steuerkurve 14a hochgleitet, entgegen der Kraft der ersten Druckfeder 9 nach hinten verschwenkt wird, wobei sich Rast­schwinge 14 und Schwinge 17 durch die starre Kopplung wie aus einem einzigen Stück verhalten. Hat das Rastelement 13c den Auslösepunkt 14b (s.Fig.3) der Steuerkurve 14a überschritten, so gleitet es entlang dem oberen Teil 14c der Steuerkurve 14a, der so ausgestaltet ist, daß der eine leichte Entspannung der ersten Druckfeder 9 zuläßt, welche die Öffnungskraft des Sohlenhalters 13 entgegen der Schließfeder 24 liefert. Nach einer reinen Vertikalauslösung ist der Fersenhalter 7 einstiegsbereit (Fig.4)In the event of a frontal fall, the sole holder 13 is pivoted vertically, the latching rocker 14 being pivoted backwards against the force of the first compression spring 9 by the latching element 13c of the sole holder 13, which slides up along the control curve 14a, with the latching rocker 14 and the rocker 17 moving through the rigid coupling behaves like a single piece. If the latching element 13c has exceeded the trigger point 14b (see FIG. 3) of the control curve 14a, it slides along the upper part 14c of the control curve 14a, which is designed such that it allows the first compression spring 9 to relax slightly, which opens the opening force the sole holder 13 delivers against the closing spring 24. After a purely vertical release, the heel holder 7 is ready for entry (Fig. 4)

Findet ein reiner Drehsturz statt, so bewegt sich die Rolle 26 entlang der Horizontalsteuerkurve 4b, wodurch der Steuerhebel 25 entgegen dem Uhr­zeigersinn verschwenkt wird, was ein Zusammendrücken der zweiten Druck­feder 10 zur Folge hat. Ab einem gewissen Schwenkwinkel der Sohlenplatte 5 kommt der Mitnehmer 27a in Kontakt mit dem Sperrhebel 22 und bei weiterer Verschwenkung nimmt dieser den Sperrhebel 2 mit, so lange bis dessen Haken 22a aus dem Eingriff mit der Schwenkachse 12 kommt (Fig.5). Ab dieser Stellung ist die Kopplung zwischen Rastschwinge 14 und Schwinge 17 aufgehoben, da der Gleitbolzen 21 nach oben ausweicht. Der Kraftschluß vom Sohlenhalter 13 zur ersten Druckfeder 9 ist unterbrochen, die Rastschwinge 14 kann kraftlos nach hinten verschwenken und damit dem Rastelement 13c den Weg nach oben freigeben, so daß der Skischuh aus dem Fersenhalter 7 freikommt (Fig.6).If there is a pure camber, the roller 26 moves along the horizontal control curve 4b, as a result of which the control lever 25 is pivoted counterclockwise, which results in the second compression spring 10 being compressed. From a certain pivoting angle of the soleplate 5, the driver 27a comes into contact with the locking lever 22 and, when pivoted further, takes the locking lever 2 with it until its hook 22a comes out of engagement with the pivoting axis 12 (FIG. 5). From this position, the coupling between the locking rocker 14 and rocker 17 is released, since the sliding pin 21 dodges upwards. The frictional connection from the sole holder 13 to the first compression spring 9 is interrupted, the latching rocker 14 can pivot forcelessly backwards and thus release the latching element 13c upwards, so that the ski boot is released from the heel holder 7 (FIG. 6).

Nachdem der Skischuh aus der Bindung entfernt ist, schließt sich der Sohlenhalter 13 aufgrund der Schließfeder 24. Dabei wird der Gleitbolzen 21 durch den ersten Schenkel 23a der Feder 23 im Langloch 14d nach unten gedrückt und der zweite Schenkel 23b der Feder 23 drückt den Haken 22a des Sperrhebels 22 unter die Schwenkachse 12, wodurch die starre Kopplung von Rastschwinge 14 und Schwinge 17 wieder hergestellt ist. Um die Bindung einstiegsbereit zu machen, muß der Sohlenhalter 13 mit dem Auslösehebel 15 geöffnet werden.After the ski boot is removed from the binding, the sole holder 13 closes due to the closing spring 24. The sliding pin 21 is pressed down by the first leg 23a of the spring 23 in the elongated hole 14d and the second leg 23b of the spring 23 presses the hook 22a of the locking lever 22 below the pivot axis 12, whereby the rigid coupling of the locking rocker 14 and rocker 17 is restored. To make the binding ready for entry, the sole holder 13 must be opened with the release lever 15.

Beim wilkürlichen Öffnen des Sohlenhalters 13 wird der Auslösehebel 15 nach unten verschwenkt, wobei die unteren Fortsätze 15c den Sohlenhalter 13 an seinen Führungsflächen 13d hochhebeln. Dabei drückt das Rastelement 13c die Rastschwinge 14 entgegen der Kraft der ersten Druckfeder 9 nach hinten. Im geöffneten Zustand ist der Fersenhalter 7 einstiegsbereit. Beim Schließen des Sohlenhalters 13 von Hand aus wird der Auslösehebel 15 nach oben verschwenkt, wobei die oberen Fortsätze 15b Führungsflächen 13d des Sohlenhalters 13 nach unten beaufschlagen.When the sole holder 13 is opened at will, the release lever 15 is pivoted downward, the lower extensions 15c levering the sole holder 13 up on its guide surfaces 13d. The locking element 13c presses the locking rocker 14 against the force of the first compression spring 9 backwards. In the open state, the heel holder 7 is ready for entry. When the sole holder 13 is closed by hand, the release lever 15 is pivoted upward, the upper extensions 15b acting on guide surfaces 13d of the sole holder 13 downward.

Bei der gezeigten Ausführung ist vorgesehen, daß die Auslösung bei einer reinen Horizontalverschwenkung zuerst über den Vorderbacken 6 erfolgen soll und sich erst anschließend auch der Fersenhalter 7 öffnet, um einem Haften des Skischuhs auf der Sohlenplatte 5 vorzubeugen, wenn Skischuhe mit Gummiprofilsohle verwendet werden. So wird bei dieser Ausführung auch keine Gleitplatte im Ballenbereich benötigt. Genauso wäre es denkbar, bei Horizontalverschwenkung den Fersenhalter 7 zuerst öffnen zu lassen, um an­schließend den Vorderbacken 6 abzukippen, wie dies bei der Lösung nach dem Stand der Technik (vgl. DE-OS 31 02 010) der Fall ist. Die Abstimmung, bei welchem Schwenkwinkel der Fersenhalter 7 den Skischuh freigibt, wird über die Distanz zwischen dem Mitnehmer 27a und dem Haken 22a des Sperrhebels 22 geregelt, wobei eine größere Distanz eine spätere Freigabe des Skischuhs bewirkt.In the embodiment shown, it is provided that the triggering should take place with a pure horizontal pivoting first over the front jaws 6 and only then does the heel holder 7 open, in order to prevent the ski boot from sticking to the soleplate 5 when ski boots with a rubber profile sole are used. With this version, no slide plate is required in the bale area. It would also be conceivable to first let the heel holder 7 open when pivoting horizontally, and then tilt the toe piece 6, as is the case with the solution according to the prior art (cf. DE-OS 31 02 010). The coordination at which pivot angle the heel holder 7 releases the ski shoe is regulated via the distance between the driver 27a and the hook 22a of the locking lever 22, a larger distance causing the ski shoe to be released later.
