Description

Die Erfindung bezieht sich auf eine Sicherheitsskibindung, insbesondere Fersenhalter, nach dem Oberbegriff des Patentanspruches 1 oder 8.The invention relates to a safety ski binding, in particular heel holder, according to the preamble of patent claim 1 or 8.

Bei derartigen diagonalauslösenden Fersenhaltern ist der Sohlenhalter gegen rein horizontale Kräfte gesperrt und kann erst nach Erreichen einer vorbestimmten Höhenlage zusammen mit dem Lagerbock seitlich ausschwenken. Um zu vermeiden, daß der Fersenhalter beim Einsteigen, insbesondere in schwierigem Gelände, seitlich ausschwenkt und damit eine Verriegeln des Fersenhalters nur schwer möglish ist, ist bei einigen bekannten Fersenhaltern ein Sperrelement vorgesehen, das einerseits beim Schließen des Fersenhalters ein seitliches Ausschwenken des Lagerbocks verhindert und andererseits den Diagonalauslösevorgang nicht behindert.In the case of such diagonally releasing heel holders, the sole holder is locked against purely horizontal forces and can only pivot out to the side together with the bearing block after a predetermined height has been reached. In order to avoid that the heel holder swings out sideways when boarding, especially in difficult terrain, and thus locking the heel holder is difficult, some known heel holders provide a locking element which, on the one hand, prevents the bearing block from swinging out sideways when the heel holder is closed, and on the other hand, the diagonal triggering process is not hindered.

Ein solcher Fersenhalter ist in der DE-OS 32 04 468 (FR-A-2 501 052) in den Fig.6 und 7 beschrieben. In der Einstiegslage greift der zweiarmige Hebel mit dem Sperrglied in übereinanderliegende Aussparungen von Schwenk- und Grundplatte und versperrt diese. In Fahrtstellung wird der Hebel über einen Ansatz, der seitlich hervorragt, durch die Seitenwand des Gehäuses entgegen der Wirkung einer Feder verschwenkt und dadurch das Sperrglied des Hebels aus den Aussparungen herausgehoben, so daß die Schwenkplatte sich wieder um die vertikale Hochachse verdrehen kann. Nachteilig ist hiebei, daß der Übergang von der ungesperrten in die gesperrte Stellung nur durch die Stellung des Gehäuses gesteuert wird, die nicht genau auf die tatsächliche Stellung des Fersenhalters, ob dieser verriegelt ist oder nicht, abstimmbar ist.Such a heel holder is described in DE-OS 32 04 468 (FR-A-2 501 052) in FIGS. 6 and 7. In the entry-level position, the two-armed lever with the locking element engages in the recesses of the swivel and base plates, one above the other, and locks them. In the driving position, the lever is pivoted against the action of a spring through an extension which projects laterally through the side wall of the housing and thereby the locking member of the lever is lifted out of the recesses, so that the swivel plate can rotate about the vertical vertical axis again. The disadvantage here is that the transition from the unlocked to the locked position is only controlled by the position of the housing, which is not precisely tunable to the actual position of the heel holder, whether it is locked or not.

In der AT-PS 372.613 wird eine Bindung mit einer Rastschwinge geschützt, über die neben der vertikalen Auslösung auch die diagonale Auslösung gesteuert wird, wobei die Rastschwinge für letztere eine im wesentlichen V-förmige Steuerkurve aufweist, die mit einer skifesten federbeaufschlagten Wippe zusammenwirkt. Die Zusammenlegung zweier Funktionen, das ist die Überwachung der vertikalen wie auch der diagonalen Auslösung, auf einen Bauteil, hat sich als ungünstig erwiesen. Das Zusammenwirken der V-förmigen Steuerkurve mit der federbeaufschlagten Wippe übt eine zentrierende Kraft auf die Rastschwinge und über diese auf die Schwenkplatte aus, sie stellt jedoch keine Versperrung von Schwenk- und Grundplatte dar.In AT-PS 372.613 a binding is protected with a locking rocker, via which, in addition to the vertical triggering, the diagonal triggering is controlled, the locking rocker for the latter having an essentially V-shaped control curve which is spring-loaded with a ski-fixed Seesaw works together. The combination of two functions, that is, the monitoring of the vertical as well as the diagonal triggering on a component, has proven to be disadvantageous. The interaction of the V-shaped control cam with the spring-loaded rocker exerts a centering force on the locking rocker and, via this, on the swivel plate, but it does not constitute a blocking of the swivel and base plate.

Die Erfindung hat sich die Aufgabe gestellt, einen Fersenhalter der eingangs genannten Art zu schaffen, der eine Zentrierung des Sohlenhalters beim Einsteigen in die Bindung auch in schwierigem Gelände bei dauernder seitlicher Belastung problemlos ermöglicht, ohne die Nachteile der oben angeführten Lösung zu besitzen.The invention has for its object to provide a heel holder of the type mentioned, which allows a centering of the sole holder when getting into the binding even in difficult terrain with constant lateral load without problems, without having the disadvantages of the above solution.

Erreicht wird das gesetzte Ziel erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 oder 8.The set goal is achieved according to the invention by the characterizing features of claim 1 or 8.

Durch die erfindungsgemäßen Maßnahmen nach Anspruch 1 ist bei geöffnetem Fersenhalter sichertgestellt, daß sich der Lagerbock in seiner Mittellage befindet und um seine Hochachse nicht ausschwenken kann. Da die Sperre bei geschlossenem Fersenhalter und bei in die Bindung eingesetztem Skischuh nicht wirksam ist, ist eine diagonale Auslösung in diesem Zustand jederzeit möglich. Durch die Steuerfläche an der Rastschwinge ist eine präzise Steuerung der Sperre mittels Hebel und Sperrglied gegeben. Beim Einsteigen in den Fersenhalter, genau in jener Stellung der Rastschwinge, bei der eine Verriegelung bereits sichergestellt ist - das ist die Stellung am Auslösepunkt -, betätigt die Steuerfläche der Rastschwinge den sich bis jetzt in Sperrstellung befindenden Hebel und bringt das Sperrglied aus der Grundplatte zum Ausrasten. Damit befindet sich das Sperrglied in jeder Stellung der Rastschwinge, in der diese die Rastnase untergreift, in einer ausgerasteten, ein seitliches Verschwenken des Lagerbocks freigebenden Lage. So wird die Diagonalauslösefunktion nicht behindert; beim Schließen des Fersenhalters hingegen wird ein seitliches Verschwenken des Lagerbocks verhindert, so daß auch in schwierigem Gelände ein unbeschwertes Einsteigen gesichert ist. Bei Öffnung des Fersenhalters erfolgt die Sperrung der Schwenkplatte erst nach Überschreiten des Auslösepunktes.With the heel holder open, the measures according to the invention ensure that the bearing block is in its central position and cannot swing out about its vertical axis. Since the lock is not effective when the heel holder is closed and the ski boot is inserted in the binding, diagonal release in this state is possible at any time. The control surface on the locking rocker provides precise control of the lock by means of a lever and locking element. When stepping into the heel holder, exactly in the position of the locking rocker in which locking is already ensured - that is the position at the release point - the control surface of the locking rocker actuates the lever that has been in the locked position until now and brings the locking member out of the base plate Freak out. So that the locking member is in each position of the locking rocker, in which it engages under the locking lug, in a disengaged position, a lateral pivoting of the bearing block releasing. So the diagonal release function is not hindered; when closing the heel holder, however, a lateral pivoting of the bearing block is prevented, so that carefree boarding is ensured even in difficult terrain. When the heel holder is opened, the swivel plate is only locked after the trigger point has been exceeded.

Durch die Merkmale des Anspruches 2 ist eine günstige Anpassung der Rastschwinge an die Steuerzone des Hebels und ein gutes Zusammenwirken von der Rastschwinge mit dem Hebel innerhalb des Elastizitätsbereiches des Fersenhalters gegeben.The features of claim 2 provide a favorable adaptation of the locking rocker to the control zone of the lever and a good interaction of the locking rocker with the lever within the elastic range of the heel holder.

Durch die Verwendung eines zweiarmigen Hebels nach den Merkmalen des Anspruches 3 können die Kraftübertragungsverhältnisse durch die Wahl der Arme je nach Bedart festgelegt werden.By using a two-armed lever according to the features of claim 3, the power transmission ratios can be determined by the choice of arms depending on the need.

Durch die Verwendung eines einarmigen Hebels nach den Merkmalen des Anspruches 4 kommt es zu einer Platzersparnis. Durch den Eingriff des Riegels unmittelbar im Bereich unterhalb der Steuerfläche der Rastschwinge erreicht man eine günstige Kraftübertragung. Außerdem erfolgt der Eingriff in einer von der Hochachse weit entfernten Position, was ein günstiges Moment bei der Verriegelung ergibt. Um dem sich entlang einer Kreisbahn bewegenden Riegel einen ungehinderten Eingriff in die Aussparungen von Schwenk- und Grundplatte zu gewährleisten, werden entweder die Aussparungen als in Skilängsrichtung verlaufende Schlitze gestaltet oder es gelangen die fakultativen Merkmale des Anspruches 4 zur Anwendung.The use of a one-armed lever according to the features of claim 4 saves space. By engaging the bolt directly in the area below the control surface of the locking rocker, a favorable power transmission is achieved. In addition, the intervention takes place in a position far away from the vertical axis, which gives a favorable moment when locking. In order to ensure that the bolt moving along a circular path has an unimpeded engagement in the recesses of the swivel and base plate, either the recesses are designed as slots running in the longitudinal direction of the ski or the optional features of claim 4 are used.

Durch die Merkmale des Anspruches 5 ergibt sich die Möglichkeit, das Sperrglied breit zu gestalten und damit eine stabilere Versperrung der Schwenkplatte mit der Grundplatte zu erreichen. Außerdem können die Toleranzbereiche größer gewählt werden.The features of claim 5 result in the possibility of making the locking member wide and thus achieving a more stable locking of the swivel plate with the base plate. In addition, the tolerance ranges can be chosen larger.

Die Merkmale des Anspruches 6 ermöglichen ein dauerndes Verbleiben des Riegels innerhalb der Aussparungen von Schwenk- und Grundplatte und ein sicheres Eingreifen des Sperrgliedes in die Grundplatte.The features of claim 6 allow a permanent stay of the bolt within the recesses of the pivot and base plate and a secure engagement of the locking member in the base plate.

Durch die Merkmale des Anspruches 7 ist ein exakt gefährtes Eingreifen des Sperrgliedes in die Aussparung der Grundplatte gewährleistet.The features of claim 7 ensure that the locking member engages precisely in the recess in the base plate.

Durch die erfindungsgemäßen Maßnahmen nach Anspruch 8 ist der Riegel mit seinem Sperrglied an einer Feder befestigt. Dadurch erübrigt sich die Verwendung eines Hebels, einer gesonderten Achse und einer zusätzlichen Feder, was zu einer Gewichtseinsparung führt.By the measures according to the invention according to claim 8, the bolt with its locking member is attached to a spring. This eliminates the need for a lever, a separate axle and an additional spring, which leads to a weight saving.

Nach den Merkmalen des Anspruches 9 ist eine vorteilhafte Befestigung der als Blattfeder gestalteten Feder an der Hochachse bzw. der Schwenkplatte erreicht, wobei die Feder an ihrem vorderen Ende den Riegel trägt.According to the features of claim 9, an advantageous fastening of the spring designed as a leaf spring to the vertical axis or the swivel plate is achieved, the spring carrying the bolt at its front end.

Durch die Art der Einspannung der Feder in den Riegel nach den Merkmalen des Anspruches 10 nimmt die Feder in ihrem der Rastschwinge zugewandten Teil eine konvexe Biegung an, die eine günstige Steuerzone ergibt.Due to the type of clamping of the spring in the bolt according to the features of claim 10, the spring in its part facing the locking rocker assumes a convex bend, which results in a favorable control zone.

Nach den Markmalen des Anspruches 11 ist eine einfache Ausgestaltung des Riegels festgelegt.According to the features of claim 11, a simple design of the bolt is defined.

Das erste Ausführungsbeispiel nach den Fig.1 bis 3 stellt einen Fersenhalter einer Sicherheitsskibindung dar. Auf der Oberseite eines Ski 1 ist mittels nicht dargestellter Schrauben eine Führungsschiene 2 befestigt, auf welcher eine Grundplatte 3 in der Längsrichtung des Ski 1 verschiebbar geführt und in an sich bekannter Weise zur Anpassung der Bindung an unterschiedlich lange Skischuhe in der jeweils gewünschten Lage verrastbar ist. Die Grundplatte 3 ist gegen die Kraft einer nicht dargestellten Schubfeder auf der Führungsschiene 2 verschiebbar, wobei die Schubfeder auf der einen Seite skifest und auf der anderen Seite an der Grundplatte 3 in an sich bekannter Weise abgestützt ist.The first embodiment according to FIGS. 1 to 3 represents a heel holder of a safety ski binding. On the top of a ski 1, a guide rail 2 is fastened by means of screws, not shown, on which a base plate 3 is slidably guided in the longitudinal direction of the ski 1 and in itself known way to adapt the binding to ski boots of different lengths can be locked in the desired position. The base plate 3 is displaceable against the force of a thrust spring, not shown, on the guide rail 2, the thrust spring being ski-proof on one side and supported on the base plate 3 on the other side in a manner known per se.

In der Grundplatte 3 ist eine als ein Drehzapfen ausgebildete Hochachse 4 vernietet, um welche eine Schwenkplatte 6 in der horizontalen Ebene, vorzugsweise gegen die Kraft einer Rückholfeder 5, verschwenkbar gelagert ist. Die Grundplatte 3 besitzt an ihrem vorderen, dem Skischuh zugewandten Ende eine Aufbiegung 3a, die eine Steuerbahn fér eine seitliche Auslösung trägt. Die Schwenkplatte 6 wird von einer Abkröpfung 3b der Grundplatte 3 an einer Bewegung in vertikaler Richtung gehindert.In the base plate 3 is a rivet 4 formed as a pivot, about which a pivot plate 6 is pivotally mounted in the horizontal plane, preferably against the force of a return spring 5. The base plate 3 has at its front end facing the ski boot a bend 3a which carries a control track for a lateral release. The swivel plate 6 is prevented from being moved in the vertical direction by an offset 3b of the base plate 3.

Mit der Schwenkplatte 6 fest verbunden ist ein Lagerbock 7, der an seiner vorderen Wand eine Rastnase 8 trägt. In seinem hinteren, der Grundplatte 3 benachbarten Bereich trägt der Lagerbock 7 eine quer zur Skilängsachse und parellel zur Oberseite des Ski 1 verlaufende Querachse 9, an der ein Sohlenhalter 10, der an seinem vorderen Ende einen Sohlenniederhalter 10a und einen Trittsporn 10b trägt, schwenkbar gelagert ist. In der vorderen Wand des Sohlenhalters 10 ist eine nach unten hin offene, im Querschnitt rechteckige Nut 10c ausgespart, in der eine Rolle 11 auf einer Achse gelagert ist, welche Rolle 11 als Rastelement der Steuerbahn an der Aufbiegung 3a der Grundplatte 3 zugeordnet ist. Der Sohlenhalter 10 trägt in seinem oberen Bereich eine Schwenkachse 12, die parallel zur Querachse 9 verläuft, an der eine Rastschwinge 13 angelenkt ist, welche sich im wesentlichen nach unten erstreckt und an ihrem unteren Ende einen Rastvorsprung 13a aufweist, welcher in der Fahrtstellung des Fersenhalters nach Fig.3 die am Lagerbock 7 ausgebildete Rastnase 8 untergreift. Die zur Skioberfläche hin weisende Fläche der Rastschwinge 13 weist eine Steuerfläche 13b auf.With the swivel plate 6, a bearing block 7 is fixed, which carries a locking lug 8 on its front wall. In its rear area adjacent to the base plate 3, the bearing block 7 carries a transverse axis 9 which runs transversely to the longitudinal axis of the ski and parallel to the top of the ski 1 and on which a sole holder 10, which has a sole retainer 10a and a step spur 10b at its front end, is pivotably mounted is. In the front wall of the sole holder 10 is a downwardly open, rectangular in cross section Notched groove 10c, in which a roller 11 is mounted on an axis, which roller 11 is assigned as a locking element of the control track on the bend 3a of the base plate 3. The sole holder 10 carries in its upper region a pivot axis 12 which runs parallel to the transverse axis 9, on which a locking rocker 13 is articulated, which extends essentially downwards and has a locking projection 13a at its lower end, which in the driving position of the heel holder 3 engages under the locking lug 8 formed on the bearing block 7. The surface of the locking rocker 13 pointing towards the ski surface has a control surface 13b.

Auf der Querachse 9 des Sohlenhalters 10 ist weiters ein, in Draufsicht betrachtet, etwa U-förmiges Federgehäuse 14 ebenfalls schwenkbar gelagert, welches in seinen Seitenwänden 14a Längsschlitze 14b aufweist, die eine Führung für einen Schieber 15 bilden. Der Schieber 15 ist von einer Auslösefeder 16 beaufschlagt, deren anderes Ende an einem Federwiderlager 17 abgestützt ist, das mittels einer drehbar im Federgehäuse 14 gelagerten Schraube 18 in der Achsrichtung der Auslösefeder 16 verstellbar ist.On the transverse axis 9 of the sole holder 10, a top view of an approximately U-shaped spring housing 14 is also pivotably mounted, which has longitudinal slots 14b in its side walls 14a, which form a guide for a slide 15. The slide 15 is acted upon by a release spring 16, the other end of which is supported on a spring abutment 17 which is adjustable in the axial direction of the release spring 16 by means of a screw 18 rotatably mounted in the spring housing 14.

In der Rastschwinge 13 ist zur Aufnahme des Schiebers 15 eine Rastpfanne 13c ausgebildet, in welche dieser in der Fahrstellung durch die Auslösefeder 16 gedrückt wird. Im Anschluß an die Rastpfanne 13c ist an der Rastschwinge 13 eine Freistellung 13d vorgesehen, in welche der Schieber 15 während des Betätigens eines Auslösehebels 19 in noch zu beschreibender Weise einrastet.In the locking rocker 13, a locking pan 13c is formed for receiving the slide 15, into which the latter is pressed in the driving position by the release spring 16. Following the locking pan 13c, an opening 13d is provided on the locking rocker 13, into which the slide 15 engages in the manner to be described while a trigger lever 19 is actuated.

Der Auslösehebel 19 übergreift den Sohlenhalter 19 auch seitlich und ist an der am Sohlenhalter 10 angeordneten Schwenkachse 12 gelagert, an welcher auch die Rastschwinge 13 angelenkt ist. Ein am Auslösehebel 19 parallel zur Schwenkachse 12 befestigter Bolzen 20 durchsetzt sowohl den Sohlenhalter 10 (in nicht dargestellten Langlöchern) als auch die Seitenwände 14a des Federgehäuses 14 in Langlöchern 14c und ist dort gleitbeweglich geführt.The release lever 19 also overlaps the sole holder 19 and is mounted on the pivot axis 12 arranged on the sole holder 10, to which the locking rocker 13 is also articulated. A bolt 20 fastened to the release lever 19 parallel to the pivot axis 12 passes through both the sole holder 10 (in elongated holes (not shown)) and the side walls 14a of the spring housing 14 in elongated holes 14c and is slidably guided there.

Die mit der Rastschwinge 13 zusammenwirkende Rastnase 8 bildet, von der Skioberseite aus betrachtet, eine Rastfläche 8a, welche in der Fahrtstellung des Fersenhalters vom Rastvorsprung 13a der Rastschwinge 13 untergriffen wird. Die Ausdehnung der Rastfläche 8a stellt den Elastizitätsbereich des Fersenhalters dar, wobei am Ende des Elastizitätsbereiches der Auslösepunkt 8b liegt.The locking lug 8 cooperating with the locking rocker 13 forms, viewed from the top of the ski, a locking surface 8a which is in the driving position of the heel holder is engaged by the locking projection 13a of the locking rocker 13. The extent of the latching surface 8a represents the elastic range of the heel holder, the trigger point 8b being at the end of the elastic range.

Diese Ausbildung ist für sich bekannt und bildet nicht den Gegenstand der Erfindung.This training is known per se and does not form the subject of the invention.

In der Schwenkplatte 6 befindet sich eine Aussparung 6a, in der quer zur Skilängsrichtung eine Achse 21 verläuft, an der ein zweiarmiger Hebel 22 angelenkt ist, dessen nach hinten weisender Arm 22a ein nach unten gerichtetes Sperrglied 23 trägt und dessen nach vorne weisender Arm 22b an seiner Oberseite eine in Form einer Nocke ausgebildete Steuerzone 24 aufweist, die bei geschlossenem Fersenhalter an der Steuerfläche 13b der Rastschwinge 13 zu liegen kommt. Die Grundplatte 3 trägt in ihrem der Hochachse 4 benachbarten Teil eine Aussparung 3c, die zum Eingriff für das Sperrglied 23 bestimmt ist. Durch eine Feder 25, die auf der Achse 21 gelagert ist, wird der Hebel 22 im Uhrzeigersinn, das ist in Sperrichtung, beaufschlagt. Der Hebel 22 stellt das Sperrelement zur Verhinderung des seitlichen Verschwenkens des Sohlenhalters 10 bzw. des Lagerbocks 7 um die Hochachse 4 beim Einsteigen in den Fersenhalter in schwierigem Gelände dar.In the swivel plate 6 there is a recess 6a, in which an axis 21 runs transversely to the longitudinal direction of the ski, to which a two-armed lever 22 is articulated, the arm 22a of which points to the rear and which has a locking member 23 directed downwards, and whose arm 22b which points forward has a control zone 24 in the form of a cam on its upper side, which comes to rest on the control surface 13b of the locking rocker 13 when the heel holder is closed. The base plate 3 has in its part adjacent to the vertical axis 4 a recess 3c which is intended for engagement by the locking member 23. A spring 25, which is mounted on the axis 21, acts on the lever 22 in the clockwise direction, that is in the reverse direction. The lever 22 represents the locking element for preventing the lateral pivoting of the sole holder 10 or the bearing block 7 about the vertical axis 4 when entering the heel holder in difficult terrain.

Im geöffneten Zustand des Fersenhalters nach Fig.1 ist das Sperrglied 23 in der Grundplatte 3 eingerastet, d.h. daß Schwenk- und Grundplatte 6,3 miteinander versperrt sind. Beim Einsteigen in den Fersenhalter wird der Sohlenhalter 10 nach unten bewegt, wobei der Rastvorsprung 13a der Rastschwinge 13 entlang der Rastnase 8 hinuntergleitet und dabei gegen die Kraft der Auslösefeder 16 zurückgeschoben wird, bis er den Auslösepunkt 8b erreicht. Am Auslösepunkt 8b beaufschlagt die Steuerfläche 13b der Rastschwinge 13 die als Nocke ausgebildete Steuerzone 24 des Hebels 22 derart, daß das Sperrglied 23 aus der Grundplatte 3 ausrastet (Fig.2) Somit wird erst beim Überschreiten des Auslösepunktes 8b, wenn sichergestellt ist, daß der Fersenhalter schließt, die Versperrung zwischen Schwenk- und Grundplatte 6,3 freigegeben. Das bewirk, daß beim Einsteigen in den geöffneten Fersenhalter, auch bei dauernder seitlicher Belastung, keine Verschwenkung des Sohlenhalters 10 stattfinden kann.In the open state of the heel holder according to Figure 1, the locking member 23 is locked in the base plate 3, ie that the pivot and base plate 6.3 are locked together. When stepping into the heel holder, the sole holder 10 is moved downward, the latching projection 13a of the latching rocker 13 sliding down along the latching lug 8 and being pushed back against the force of the release spring 16 until it reaches the release point 8b. At the trigger point 8b, the control surface 13b of the locking rocker 13 acts on the control zone 24 of the lever 22 designed as a cam such that the locking member 23 disengages from the base plate 3 (FIG. 2). Thus, only when the trigger point 8b is exceeded, if it is ensured that the Heel holder closes, the blockage between swivel and base plate 6.3 released. This has the effect that when the heel holder is climbed into the open heel holder, even with constant lateral load, the sole holder 10 cannot be pivoted.

Wirkt bei geschlossenem Fersenhalter nach Fig.3 auf den Sohlenhalter 10 in vertikaler Richtung eine Kraft nach oben, so schwenkt der Sohlenhalter 10 um seine Querachse 9 hoch. Während dieser Schwenkbewegung gleitet die Rastschwinge 13 mit ihrem Rastvorsprung 13a entlang der Rastfläche 8a und drückt den Schieber 15 gegen die Kraft der Auslösefeder 16 in den Längsschlitzen 14b des Federgehäuses 14 zurück. Bei der Schwenkbewegung des Sohlenhalters 10 wird auch das Federgehäuse 14 um die Querachse 9 in gleicher Weise mitverschwenkt, so daß die Rastschwinge 13 unter der Wirkung der Auslösefeder 16 verbleibt. Sobald der Rastvorsprung 13a der Rastschwinge 13 den am Ende der Rastfläche 8a liegenden Auslösepunkt 8b überschritten hat, was einem Überschreiten des Elastizitätsbereiches gleichkommt, schwenkt der Sohlenhalter 10 unterstützt von einer nicht dargestellten Öffnungsfeder in seine Offenstellung. Hiebei kann sich die Auslösefeder 16 entspannen bis der Schieber 15 an den der Rastschwinge 13 zugewandten Endbereichen der Längsschlitze 14b des Federgehäuses 14 anschlägt. Der Fersenhalter befindet sich nun wieder in seiner einstiegsbereiten Lage nach Fig.1.If a force is exerted on the sole holder 10 in the vertical direction when the heel holder according to FIG. 3 is closed, the sole holder 10 swings up about its transverse axis 9. During this pivoting movement, the latching rocker 13 slides with its latching projection 13a along the latching surface 8a and presses the slider 15 back against the force of the release spring 16 in the longitudinal slots 14b of the spring housing 14. During the pivoting movement of the sole holder 10, the spring housing 14 is also pivoted about the transverse axis 9 in the same way, so that the locking rocker 13 remains under the action of the release spring 16. As soon as the latching projection 13a of the latching rocker 13 has exceeded the trigger point 8b located at the end of the latching surface 8a, which is equivalent to exceeding the elastic range, the sole holder 10 pivots into its open position, supported by an opening spring (not shown). The release spring 16 can relax here until the slide 15 strikes the end regions of the longitudinal slots 14b of the spring housing 14 facing the locking rocker 13. The heel holder is now back in its ready-to-go position according to Fig. 1.

Bei geschlossenem Fersenhalter nach Fig.3 wird der Hebel 22 durch die Steuerfläche 13b der Rastschwinge 13 so beaufschalgt, daß sich das Sperrglied 23 oberhalb der Grundplatte 3 befindet. Die Schwenkplatte 6 kann sich relativ zur Grundplatte 3 ungehindert bewegen und der Fersenhalter kann in vertikaler als auch in "diagonaler" Richtung auslösen. Solange sich der Fersenhalter im Elastizitätsbereich befindet, d.h. solange sich der Rastvorsprung 13a der Rastschwinge 13 auf der Rastfläche 8a bewegt, gilt diese Bedingung für das Sperrglied 23. Bei einer vertikalen Auslösung kann von dem Moment an, da sich der Rastvorspring 13a der Rastschwinge 13 am Auslösepunkt 8b befindet, das Sperrglied 23 in die Aussparung 3c der Grundplatte 3 eingreifen. Bei einer "diagonalen" Auslösung, d.h. wenn bei der Öffnung des Fersenhalters der Sohlenhalter 10 auch horizontal verschwenkt ist, kommt es erst nach Freigabe des Schuhs, nachdem der Sohlenhalter 10 aufgrund der Rückholfeder 5 in seine unverschwenkte Ausgangslage zurückgekehrt ist, zum Einrasten des Sperrgliedes 23 und damit zur Verriegelung von Schwenk- und Grundplatte 6,3.When the heel holder according to FIG. 3 is closed, the lever 22 is actuated by the control surface 13b of the locking rocker 13 such that the locking member 23 is located above the base plate 3. The swivel plate 6 can move unhindered relative to the base plate 3 and the heel holder can trigger in the vertical as well as in the "diagonal" direction. As long as the heel holder is in the elastic range, ie as long as the locking projection 13a of the locking rocker 13 moves on the locking surface 8a, this condition applies to the locking member 23. With a vertical release, from the moment that the locking projection 13a of the locking rocker 13 is on Trigger point 8b is located, the locking member 23 engage in the recess 3c of the base plate 3. With a "diagonal" triggering, ie when opening the Heel holder of the sole holder 10 is also pivoted horizontally, it only comes after the release of the shoe, after the sole holder 10 has returned to its non-pivoted starting position due to the return spring 5, that the locking member 23 snaps into place and thus locks the pivoting and base plate 6,3.

Bei der willkürlichen Öffnung des Fersenhalters von Hand aus wird der Auslösehebel 19 in Richtung des in Fig.3 eingezeichneten Pfeiles Pf hochgeschwenkt. Durch den dabei nach oben mitverschwenkten Bolzen 20 wird das Federgehäuse 14 um die Querachse 9 verschwenkt, wobei der Schieber 15 gegen die Kraft der Auslösefeder 16 aus der Rastpfanne 13c der Rastschwinge 13 freikommt und die Auslösefeder 16 sich entspannen kann. Nach Loslassen des Auslösehebels 19 verbleibt der Schieber 15 in der an die Rastpfanne 13c anschließenden Freistellung 13d der Rastschwinge 13. Bei der Aufwärtsbewegung des Sohlenhalters 10 unter Wirkung der Öffnungsfeder gleitet die Rastschwinge 13, die nun nicht mehr federbelastet ist, an der Rastnase 8 des Lagerbocks 7 nach oben. Die Regenerierung des von Hand aus geöffneten Fersenhalters in die einstiegsbereite Lage, die darin besteht, den Schieber 15 aus der Freistellung 13d der Rastschwinge 13 wieder in die Rastpfanne 13c rückzuführen, erfolgt in bekannter Weise durch eine geeignete Feder, die nicht dargestellt wird, da unwesentlich für die vorliegende Erfindung.When the heel holder is opened by hand, the release lever 19 is pivoted up in the direction of the arrow Pf shown in FIG. The spring housing 14 is pivoted about the transverse axis 9 by the pin 20 pivoted upwards, the slide 15 being released against the force of the release spring 16 from the locking pan 13c of the locking rocker 13 and the release spring 16 being able to relax. After releasing the release lever 19, the slide 15 remains in the freeing 13d of the locking rocker 13 adjoining the locking pan 13c. When the sole holder 10 moves upwards under the action of the opening spring, the locking rocker 13, which is now no longer spring-loaded, slides on the locking lug 8 of the bearing block 7 up. The regeneration of the heel holder, which is opened by hand, into the position ready for entry, which consists in returning the slider 15 from the release 13d of the locking rocker 13 back into the locking pan 13c, is carried out in a known manner by means of a suitable spring, which is not shown because it is immaterial for the present invention.

Die zweite Ausführungsform nach den Fig.4 bis 8 unterscheidet sich von der ersten durch die Ausgestaltung des Hebels 22ʹ mit dem Sperrglied 23ʹ. Der einarmig ausgeführte Hebel 22ʹ ist an der Achse 21 angelenkt und erstreckt sich nach vorne, wobei sein Endbereich an der Oberseite als Steuerzone 24ʹ ausgebildet ist. An seinem vorderen Ende trägt der Hebel 22ʹ einen Riegel 26, der das Sperrglied 23ʹ beinhaltet. Der Riegel 26 weist in Vorderansicht die Form eines umgekehrten T auf (Fig.8). Sein Längsbalken 26a tritt durch die Aussparungen 6ʹa,3ʹc von Schwenk- un Grundplatte 6ʹ,3ʹ hindurch und ist bogenförmig entsprechend dem Drehpunkt des Hebels 22ʹ um die Achse 21 geformt. Die Aussparung 3ʹc der Grundplatte 3ʹ ist kreisbogenförmig mit der Hochachse 4 als Zentrum gestaltet, da der Riegel 26 immer in Eingriff mit der Grundplatte 3ʹ ist, wobei ihre Breite durch den maximalen Schwenkwinkel der Schwenkplatte 6ʹ gegeben ist. Der Querbalken des Riegels 26 ist als Sperrglied 23ʹ wirksam, das für den Eingriff in die Aussparung 3ʹc der Grundplatte 3ʹ bei geöffnetem Fersenhalter bestimmt ist und deshalb kreisbogenförmig entsprechend der Aussparung 3ʹc gestaltet sein muß. Durch die Feder 25ʹ wird der Hebel 22ʹ nach oben, das ist in Sperrichtung, beaufschlagt. Die Steuerzone 24ʹ des Hebels 22ʹ und die Steuerfläche 13ʹb der Rastschwinge 13ʹ sind so aufeinander abgestimmt, daß sich der Hebel 22ʹ, solange sich der Fersenhalter im Elastiztätsbereich befindet, nicht bewegt, was aus Platzgründen erforderlich ist.The second embodiment according to Figures 4 to 8 differs from the first by the design of the lever 22ʹ with the locking member 23ʹ. The single-arm lever 22ʹ is articulated on the axis 21 and extends forward, with its end region on the top being designed as a control zone 24ʹ. At its front end, the lever 22ʹ carries a bolt 26, which includes the locking member 23ʹ. The bolt 26 has the shape of an inverted T in a front view (FIG. 8). Its longitudinal beam 26a passes through the recesses 6a, 3c from the swivel and base plate 6ʹ, 3ʹ and is shaped in an arc shape around the axis 21 in accordance with the pivot point of the lever 22ʹ. The recess 3ʹc of the base plate 3ʹ is a circular arc with the The vertical axis 4 is designed as the center, since the bolt 26 is always in engagement with the base plate 3ʹ, its width being given by the maximum swivel angle of the swivel plate 6ʹ. The crossbar of the bolt 26 is effective as a locking member 23ʹ, which is intended for engagement in the recess 3ʹc of the base plate 3ʹ with the heel holder open and must therefore be designed in a circular arc corresponding to the recess 3ʹc. The spring 22ʹ acts on the lever 22ʹ upwards, that is in the reverse direction. The control zone 24ʹ of the lever 22ʹ and the control surface 13ʹb of the locking rocker 13ʹ are coordinated so that the lever 22ʹ does not move as long as the heel holder is in the elastic range, which is necessary for reasons of space.

Bei der dritten Ausführungsform nach den Fig.9 und 10 ist der Riegel 26ʺ mit seinem Sperrglied 23ʺ an einer als Blattfeder ausgestalteten Feder 25ʺ befestigt, die im Bereich der Hochachse 4 in einer Ausnehmung 6ʺb der Schwenkplatte 6ʺ gehalten ist. Zur Befestigung des Riegels 26ʺ ist der freie Endbereich der Feder 25ʺ über das obere Ende des Riegels 26ʺ nach hinten gebogen und das gabelförmig gestaltete Ende der Feder 25ʺ in den Schlitzen 26ʺb des Riegels 26ʺ verankert. Durch diese Art der Befestigung erreicht man auf einfache Weise zugleich die Ausformung der Steuerzone 24ʺ. Durch die Verwendung einer Feder 25ʺ statt eines starren Hebelarmes kann die Form des Riegels 26ʺ vereinfacht und damit gerade ausgebildet sein. Die Feder 25ʺ hat eine derartige Vorspannung, daß sie den Riegel 26ʺ nach oben, das ist in Sperrichtung, beaufschlagt.In the third embodiment according to FIGS. 9 and 10, the bolt 26ʺ is fastened with its locking member 23ʺ to a spring 25ʺ designed as a leaf spring, which is held in the region of the vertical axis 4 in a recess 6ʺb of the swivel plate 6ʺ. To fasten the bolt 26ʺ, the free end region of the spring 25ʺ is bent back over the upper end of the bolt 26ʺ and the fork-shaped end of the spring 25ʺ is anchored in the slots 26ʺb of the bolt 26ʺ. With this type of attachment you can easily achieve the shape of the control zone 24ʺ. By using a spring 25ʺ instead of a rigid lever arm, the shape of the bolt 26ʺ can be simplified and thus straight. The spring 25ʺ has such a bias that it engages the bolt 26ʺ upwards, that is in the reverse direction.

Die Erfindung ist auf die dargestellten Ausführungsbeispiele nicht eingeschränkt. Es sind weitere Abwandlungen denkbar, ohne den Rahmen des Schutzumfanges zu verlassen. So ist es durchaus möglich, die Beaufschlagung des zweiarmigen Hebels durch eine Blattfeder zu verwirkliche, die im Bereich der Hochachse befestigt ist und den nach hinten weisenden Arm des Hebels von oben beaufschlagt. Bei der dritten Ausführungsform ist es möglich, statt einer breiten Blattfeder mit gabelförmig gestaltetem Endbereich zwei schmale Blattfedern zu verwenden, die in den Schlitzen des Riegels verankert werden.

The invention is not restricted to the exemplary embodiments shown. Further modifications are conceivable without leaving the scope of the scope of protection. It is therefore entirely possible to implement the action of the two-armed lever by means of a leaf spring which is fastened in the region of the vertical axis and acts on the arm of the lever pointing towards the rear from above. In the third embodiment it is possible to use two narrow leaf springs instead of a wide leaf spring with a fork-shaped end region, which are anchored in the slots of the bolt.

A heel clamp assembly according to claims 1 and 5, characterized in that the transverse dimension of said aperture (6'a) of said swivel plate (6') substantially corresponds to that of said upright web (26a) of said bolt member (26) for the latter to extend through said swivel plate (6'), that said recess (3'c) of said base plate (3') is of circular arcuate shape so as to accommodate the maximum pivoting range of said bolt member (26) in unison with said swivel plate (6'), and that said transverse flange of said bolt member (26) acting as said locking member (23') has a curvature corresponding to said circular arcuate recess (3'c) of said base plate (3') for interlocking said swivel and base plates (3', 6') (fig. 7).
  7. A heel clamp assembly according to claims 5 and 6, characterized in that the upwards facing edges of said locking member and the downwards facing edges of said recess of said base plate are chamfered.
  8. A safety ski binding, particularly a heel clamp assembly, comprising a sole clamp (10) mounted for pivoting upwards about a transverse axle pin (9) on a mounting body consisting of a swivel plate (6") and a bearing block (7) fixedly connected thereto, a detent arm (13") biased by a release spring (16) and cooperating with a detent nose (8) provided at a fixed position on said bearing block, to prevent said sole clamp (10) from pivoting in the vertical direction, said mounting body being mounted on an upright axle pin (4) provided on a base plate (3") and acting as a journal, for pivoting in a plane extending at approximately right angles to the pivoting plane of said sole clamp (10), said mounting body being likewise lockable by virtue of said sole clamp (10) being formed with a detent element engaged in a curved cam path provided on said base plate (3") for controlling the lateral release operation of said base plate (3") and sole clamp (10) relative to one another, a release lever (19) acting indirectly or directly on said detent arm (13") for the intentional release of the heel clamp assembly, said mounting body being prevented from pivoting in the open position of said sole clamp (10) by a locking mechanism composed of a locking member (23") biased by a spring (25") in the locking direction, and a locking detent therefor, said locking detent for said locking member (23") being formed by at least one recess (3c") in said base plate (3"), said locking member (23") optionally also extending through an aperture (6a") formed in said swivel plate (6") above said recess (3c") of said base plate (3"), characterized in that said spring (25") acting on said locking member (23") is preferably a leaf spring, that this spring (25") at the same time acts as a retention member for said locking member (23"), and that said detent arm (13") is provieded with a cam face (13"b) acting on said spring (25") at the location of a control section (24"), so that said spring (25") is maintained in a disengaged state permitting said bearing block (7) to pivot laterally relative to said base plate (3") in any position of said detent arm (13") in which the latter is engaged below said detent nose (8) (fig. 9).
  9. A heel clamp assembly according to claim 8, characterized in that said leaf spring acting as said spring (25") has its rear end secured on or in said swivel plate (6") adjacent said upright axle pin (4), and carries at its front end a bolt member (26") on which said locking member (23") is provided (fig. 9).
  10. A heel clamp assembly according to claim 9, characterized in that said leaf spring acting as said spring (25") has its free end portion formed in a fork-shaped configuration and bent rearwards, and that this free end portion of said spring (25") encloses the upper end of said bolt member (26"), with the fork points of said spring (25") are anchored in slots (26"b) of said bolt member (26") (figs. 9 and 10).
  11. A heel clamp assembly according to claim 9, characterized in that said bolt member (26") comprises a linearly extending longitudinal Web portion (26"a) adapted to be displaced relative to said swivel plate (6") substantially in a vertical plane (figs. 9 and 10).
