At the same time, the unit 13 is also pushed away from the parting plane 18 as a result of the compression spring 15, which only makes pivoting possible. This pushing away of the unit 13 comes about because the compression spring 15, which acts on the end of the articulated bracket 16 mounted in the release lever 8, shifts the latter due to its elongated hole 16 'towards the ski tip. Accordingly, the unit 13 receives a movement composed of a rotation and a translation, which is limited by the stop surfaces 22 and 22 'on the release lever. In this way it is possible, even after the toe piece has been released, to re-enter the ski binding with the ski boot alone without the release lever 8 having to be pivoted by hand beforehand.

Description

Die Erfindung bezieht sich auf einen Fersenhalter mit einer am Ski zu befestigenden bzw. in Skilängsrichtung verstell- und feststellbaren Grundplatte, an der ein eine Rastfeder und einen Rastbolzen aufnehmendes Gehäuse angeordnet ist, das gegebenenfalls um eine auf die Skioberseite normale Achse gegenüber der Grundplatte verschwenkbar ist und welches Gehäuse auf einer Querachse eine aus einem Trittsporn und einem Niederhalteteil bestehende Einheit trägt, welche unter dem Einfluß mindestens einer sie nach oben zu schwenken suchenden Schenkelfeder steht, welcher Einheit ein mit einer dem Rastbolzen zugeordneten Steuerkurve ausgestatteter Auslösehebel zugeordnet ist.The invention relates to a heel holder with a base plate to be fastened to the ski or adjustable and lockable in the longitudinal direction of the ski, on which a housing accommodating a locking spring and a locking bolt is arranged, which can optionally be pivoted about an axis normal to the top of the ski relative to the base plate and which housing carries on a transverse axis a unit consisting of a step spur and a hold-down part, which is under the influence of at least one leg spring which tries to pivot it upwards, to which unit is assigned a release lever equipped with a control cam assigned to the locking pin.

Der Fersenhalter dieser nicht druckschriftlich vorveröffentlichten Art (DE-A-3 104 633) war zwar sehr einfach in seiner Konstruktion und äußerst robust in seinem Aufbau, er hatte jedoch den Nachteil, daß im Falle einer unwillkürlichen Auslösung des Vorderbackens der Skibindung der Auslösehebel, der mit dem Trittsporn und dem Niederhalteteil einstückig ausgebildet war, zum Wiedereinsteigen des Skischuhes von Hand in die Einsteigstellung geschwenkt werden mußte.The heel holder of this non-pre-published type (DE-A-3 104 633) was very simple in its construction and extremely robust in its construction, but it had the disadvantage that in the event of an involuntary release of the toe of the ski binding, the release lever, the was formed in one piece with the step spur and the hold-down part, had to be pivoted by hand into the entry position to re-enter the ski boot.

Eine andere Ausführungsform eines Fersenhalters zeigt die AT-PAS-306 591. Bei diesem Fersenhalter ist der Auslösehebel auf einer im Gehäuse gelagerten, mit einer Abflachung versehenen Welle befestigt, und die Einheit aus Trittsporn und Niederhalteteil, die von einer die Einheit nach oben zu schwenken suchenden Schenkelfeder beaufschlagt wird, ist auf einer Achse im Gehäuse schwenkbar gelagert. An der Abflachung der Welle liegt ein von der Rastfeder belasteter Kolben an. Der Auslösehebel ist U-förmig und trägt an seiner Vorderseite Steuerkurven, die mit Rollen an der Einheit zusammenarbeiten. Auch dieser Fersenhalter hat den Nachteil, daß er bei einem unwillkürlichen Auslösen des Vorderbackens in der Fahrtstellung verbleibt.Another embodiment of a heel holder is shown in AT-PAS-306 591. In this heel holder, the release lever is fastened to a shaft which is mounted in the housing and is provided with a flattened portion, and the unit comprising a step spur and hold-down part, which swings the unit upwards from one seeking torsion spring is pivotally mounted on an axis in the housing. A piston loaded by the detent spring rests on the flattened portion of the shaft. The trigger lever is U-shaped and has control cams on its front that work with rollers on the unit. This heel holder also has the disadvantage that it remains in the driving position in the event of an involuntary triggering of the toe piece.

Es sind zwar bereits Fersenhalter vorgeschlagen worden, welche immer bereit für den Einstieg des Skischuhes waren, egal ob der Fersenhalter willkürlich oder unwillkürlich ausgelöst worden war bzw. nur beim Vorderbacken eine unwillkürliche Auslösung stattgefunden hatte (s. AT-PA-341 393), doch waren diese Fersenhalter in ihrer Konstruktion etwas aufwendig.Heel holders have always been suggested, which were always ready for the ski boot to come in, regardless of whether the heel holder was triggered voluntarily or involuntarily or only when the toe was involuntarily triggered (see AT-PA-341 393), however these heel brackets were somewhat complex in their construction.

Die Erfindung setzt sich zum Ziel, die angeführten Nachteile der bekannten Ausführungsformen zu beseitigen und einen Fersenhalter gemäß der oben angegebenen Gattung zu schaffen, der einerseits nach jeder Art der Auslösung für den Einstieg des Skischuhes bereit ist, anderseits aber in seinem Aufbau äußerst einfach ist. Weiters soll beim Einsteigen eine Relativbewegung zwischen der aus Trittsporn und Niederhalteteil bestehenden Einheit und dem Auslösehebel zwar möglich sein, in der Fahrtstellung jedoch soll eine derartige Relativbewegung, welche zu einem Ausleiern der Gelenke führen kann, unterbunden werden.The invention aims to eliminate the disadvantages of the known embodiments and to create a heel holder according to the type specified above, which is ready for the entry of the ski boot after any type of triggering, but on the other hand is extremely simple in its construction. Furthermore, when boarding, a relative movement between the unit consisting of the tread and hold-down part and the release lever should be possible, but in the driving position, such a relative movement, which can lead to wear of the joints, should be prevented.

Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß die Einheit, die vorzugsweise in der Fahrtstellung.längs einer Trennebene am Auslösehebel anliegt, mit dem um die Querachse des Gehäuses verschwenkbaren Auslösehebel gelenkig verbunden ist und unter dem Einfluß mindestens einer Druckfeder steht, welche die Einheit von der Querachse bzw. vom Auslösehebei weg zu drücken trachtet, und daß die Einheit mit dem Auslösehebel in der Fahrtstellung mittels eines Ansatzes, der in eine Aussparung einrastet, verriegelt ist.This goal is achieved according to the invention in that the unit, which preferably rests in the driving position along a separation plane on the release lever, is articulated to the release lever pivotable about the transverse axis of the housing and is under the influence of at least one compression spring which separates the unit from the Trying to push the transverse axis or away from the release lever, and that the unit with the release lever in the travel position is locked by means of an extension which snaps into a recess.

Dabei hat es sich als besonders vorteilhaft erwiesen, wenn gemäß einem weiteren Merkmal der Erfindung zur gelenkigen Verbindung der Einheit mit dem Auslösehebel mindestens eine Gelenklasche vorgesehen ist, deren von der Querachse des Auslösehebels durchsetzte Ausnehmung als Langloch ausgebildet ist, wogegen die Querachse der Einheit eine Bohrung in der Gelenkachse durchsetzt, und wenn die bzw. jede Druckfeder in einer Sackbohrung im Auslösehebel untergebracht ist. Dadurch wird besonders in der Anfangsphase der Kombinierten Bewegung der Einheit eine große Beschleunigung erreicht. Die Erfindung sieht ferner vor, daß die Achse der Sackbohrung mit der Achse der Gelenklasche in der Fahrtstellung des Fersenhalters fluchtet und die in ihrem vorderen Bereich dem Querschnitt der Gelenklasche entsprechend und deren Schwenkbewegung zulassend ausgebildet ist. Durch diese Maßnahme ist bei einer Auslösung der Bindung ein Wegbewegen der Einheit vom Auslösehebel auch dann gewährleistet, wenn der Fersenhalter verschmutzt oder durch Eiskristalle verunreinigt ist.It has proven to be particularly advantageous if, according to a further feature of the invention, at least one hinge plate is provided for the articulated connection of the unit to the release lever, the recess of which the transverse axis of the release lever is designed as an elongated hole, whereas the transverse axis of the unit has a bore penetrates in the hinge axis, and when the or each compression spring is accommodated in a blind hole in the release lever. As a result, great acceleration is achieved, particularly in the initial phase of the combined movement of the unit. The invention further provides that the axis of the blind bore is aligned with the axis of the hinge plate in the driving position of the heel holder and which is designed in its front region in accordance with the cross section of the hinge plate and allowing its pivoting movement. When the binding is released, this measure ensures that the unit moves away from the release lever even if the heel holder is dirty or contaminated by ice crystals.

Für eine besonders kompakte Bauweise hat sich als zweckmäßig erwiesen, wenn erfindungsgemäß die Querachse für den Auslösehebel in letzterem in Lageraugen gelagert ist, welche am Auslösehebel angesetzt sind und über die Trennebene zwischen der Einheit und dem Auslösehebel in Ausnehmungen der Einheit seitlich vorragen. Dadurch wird auch die vom Ansatz hervorgerufene Verrastung verbessert.For a particularly compact design, it has proven to be advantageous if, according to the invention, the transverse axis for the release lever is mounted in bearing eyes in the latter, which are attached to the release lever and protrude laterally into recesses in the unit via the parting plane between the unit and the release lever. This also improves the latching caused by the approach.

Als besonders vorteilhaft hat es sich erwiesen, wenn erfindungsgemäß in der Fahrtstellung der Ansatz der Einheit und die Aussparung im Auslösehebel unterhalb der beiden Lageraugen des Auslösehebels liegen. Infolge dieses Merkmales geht die Resultierende der von der Ferse des Skischuhes in horizontaler Richtung auf den Fersenhalter ausgeübten Kräfte zumindest angenähert durch den Ansatz, was dessen Eindringen in die Ausnehmung noch verstärkt.It has proven to be particularly advantageous if, according to the invention, the attachment of the unit and the cutout in the release lever lie below the two bearing eyes of the release lever in the travel position. As a result of this feature, the resultant of the forces exerted on the heel holder by the heel of the ski shoe in the horizontal direction goes at least approximately through the shoulder, which further increases its penetration into the recess.

Ferner sieht die Erfindung vor, daß zur Begrenzung der kombinierten Bewegung der Einheit bzw. der Gelenklasche gegenüber dem Auslösehebel an letzterem Anschlagflächen angeordnet sind. Durch diese wird der Schwenkwinkel der Einheit auf etwa 36° und der der Gelenklasche auf etwa 72° begrenzt.Furthermore, the invention provides that in order to limit the combined movement of the unit or the joint plate relative to the release lever, stop surfaces are arranged on the latter. Through this the swivel angle the unit is limited to approximately 36 ° and that of the link plate to approximately 72 °.

Selbstverständlich bieten sich verschiedene Möglichkeiten an, die Schenkelfeder, welche die Schwenkbewegung der Einheit gegenüber dem Auslösehebel herbeiführen sollen, unterzubringen. Als konstruktiv besonders einfach hat es sich jedoch erwiesen, wenn in weitere Ausgestaltung der Erfindung die bzw. jede Schenkelfeder auf der Querachse für den Auslösehebel gelagertz ist, wobei ein Schenkel der Schenkelfeder sich an einer Anschlagfläche des Auslösehebels abstützt, der andere Schenkel hingegen mit seinem abgebogenen Ende in einer schlitzartigen Ausnehmung der Einheit untergebracht ist. Dabei wird durch das abgebogene Schenkelende ein Gleiten des Schenkels in der Längsrichtung der Ausnehmung während der kombinierten Bewegung der Einheit ermöglicht.Of course, there are various options for accommodating the leg spring, which should bring about the pivoting movement of the unit relative to the release lever. It has proven to be structurally particularly simple, however, if, in a further embodiment of the invention, the or each leg spring is mounted on the transverse axis for the release lever, one leg of the leg spring being supported on a stop surface of the release lever, the other leg, on the other hand, being bent End is housed in a slot-like recess of the unit. The bent leg end allows the leg to slide in the longitudinal direction of the recess during the combined movement of the unit.

Für die gegenseitige Anordnung der Federn gibt es natürlich verschiedene Lösungen. Als besonders vorteilhaft hat es sich jedoch erwiesen, wenn die Gelenklasche und die Druckfeder(n) im mittleren Bereich des Auslösehebels symmetrisch zu dessen vertikaler Längsmittelebene angeordnet sind, wogegen die beiden Schenkelfedern sich zu beiden Seiten der Gelenklasche im Abstand von dieser befinden.There are of course various solutions for the mutual arrangement of the springs. However, it has proven to be particularly advantageous if the hinge plate and the compression spring (s) are arranged symmetrically to the vertical longitudinal center plane in the central region of the release lever, whereas the two leg springs are at a distance from the hinge plate on both sides.

In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes rein schematisch dargestellt. Fig. 1 zeigt einen erfindungsgemäßen Fersenhalter in der Einsteiglage im Längsschnitt und Fig. denselben in der Fahrtstellung, gleichfalls im Längsschnitt, Fig.3 gibt ein Detail des in Fahrtstellung befindlichen Fersenhalters im Schnitt nach der Linie 111-111 in Fig. 4 und Fig. 4 einen Schnitt nach der Linie IV-IV in Fig. 3 wieder.In the drawing, an example embodiment of the subject matter of the invention is shown purely schematically. 1 shows a heel holder according to the invention in the entry position in a longitudinal section and FIG. The same in the driving position, likewise in a longitudinal section, FIG. 3 shows a detail of the heel holder in the driving position in section along the line 111-111 in FIG. 4 and FIG. 4 shows a section along the line IV-IV in Fig. 3 again.

In den Fig. 1 und 2 ist mit 1 ein Ski bezeichnet, auf dessen Oberseite 1a eine Führungsschiene 2 befestigt ist. An dieser ist die Grundplatte 3 eines Fersenhalters verschiebbar geführt. Sie ist durch an sich bekannte, der Übersichtlichkeit halber nicht dargestellte Mittel in der gewählten Lage feststellbar. An der Grundplatte 3 ist ein eine Rastfeder 4 und einen Rastbolzen 10 od. dgl. aufnehmendes Gehäuse 5 auf einer vertikalen Achse 6 verdrehbar gelagert. Das Gehäuse 5 besitzt auf der dem Skischuh zugewandten Seite zwei Lageraugen 5', in denen eine Querachse 7 für einen Auslösehebel 8 angeordnet ist. Dieser trägt an seiner Unterseite eine Steuerkurve 9, welche dem Rastbolzen 10 od. dgl. zugeordnet ist, der von der Rastfeder 4 beaufschlagt wird und im Gehäuse 5 in Richtung seiner Achse verschiebbar geführt ist.1 and 2, 1 denotes a ski, on the top 1a of which a guide rail 2 is fastened. On this the base plate 3 of a heel holder is guided. It can be determined in the selected position by means known per se, not shown for the sake of clarity. On the base plate 3, a catch spring 4 and a catch bolt 10 or the like. Housing 5 is rotatably mounted on a vertical axis 6. The housing 5 has two bearing eyes 5 ′ on the side facing the ski boot, in which a transverse axis 7 for a release lever 8 is arranged. This carries on its underside a control cam 9, which is assigned to the locking pin 10 or the like, which is acted upon by the locking spring 4 and is guided in the housing 5 so as to be displaceable in the direction of its axis.

An seiner Vorderseite trägt der Auslösehebel 8 eine aus einem Trittsporn 11 und einem Niederhalteteil 12 bestehende Einheit 13. Diese ist mit dem Auslösehebel 8 gelenkig verbunden und steht unter dem Einfluß von zwei Schenkelfedern 14, welche die Einheit 13 nach oben zu schwenken suchen, sowie mindestens einer Druckfeder 15, welche die Einheit 13 von der Querachse 7 bzw. vom Auslösehebel 8 wegzudrücken trachtet. Dabei wird die gelenkige Verbindung der Einheit 13 mit dem Auslösehebel 8 durch eine Gelenklasche 16 herbeigeführt, deren von der Querachse 7 durchsetzte Ausnehmung 16' als Langloch ausgebildet ist, wogegen die Querachse 17 der Einheit 13 eine Bohrung 16" der Gelenklasche 16 durchsetzt.On its front, the release lever 8 carries a unit 13 consisting of a tread 11 and a hold-down part 12. This unit is articulated to the release lever 8 and is under the influence of two leg springs 14, which seek to pivot the unit 13 upwards, and at least a compression spring 15 which tries to push the unit 13 away from the transverse axis 7 or from the release lever 8. The articulated connection of the unit 13 with the release lever 8 is brought about by an articulated bracket 16, the recess 16 'of which the transverse axis 7 passes through is formed as an elongated hole, whereas the transverse axis 17 of the unit 13 passes through a bore 16 "of the articulated link 16.

Von den Federn 14 und 15 ist letztere in einer Sackbohrung 8" im Auslösehebel 8 untergebracht, deren Achse in der Fahrtstellung des Fersenhalters mit der Achse der Gelenklasche 16 fluchtet und die in ihrem vorderen Bereich dem Querschnitt der Gelenklasche 16 entsprechend und deren Schwenkbewegung zulassend ausgebildet ist. Durch diese Ausbildung wird eine einwandfreie Führung der Gelenklasche 16 in der Bohrung 8" sichergestellt, gleichgültig ob die Gelenklasche, wie in Fig.4 dargestellt, einen Kreisquerschnitt besitzt oder aber auch aus einem Flachstahl mit Rechteckprofil hergestellt ist. Die beiden Schenkelfedern 14 befinden sich zu beiden Seiten der Gelenklasche 16 und sind auf der Querachse 7 für den Auslösehebel 8 gelagert. Der eine Schenkel 14' jeder Schenkelfeder 14 stützt sich an einer Anschlagfläche 8' des Auslösehebels 8 ab, wogegen der andere Schenkel 14" in einer schlitzartigen Ausnehmung 13' in der aus Trittsporn 11 und Niederhalteteil 12 bestehenden Einheit 13 untergebracht ist. Das Ende des Schenkels 14" ist bogenförmig ausgebildet, um das Gleiten in der Ausnehmung 13' zu erleichtern.Of the springs 14 and 15, the latter is accommodated in a blind bore 8 ″ in the release lever 8, the axis of which is aligned with the axis of the joint plate 16 in the driving position of the heel holder and which is designed in its front region to correspond to the cross section of the joint plate 16 and to permit its pivoting movement This design ensures that the joint plate 16 is guided properly in the bore 8 ″, irrespective of whether the joint plate, as shown in FIG. 4, has a circular cross section or is also made from a flat steel with a rectangular profile. The two leg springs 14 are located on both sides of the link plate 16 and are mounted on the transverse axis 7 for the release lever 8. One leg 14 'of each leg spring 14 is supported on a stop surface 8' of the release lever 8, while the other leg 14 "is accommodated in a slot-like recess 13 'in the unit 13 consisting of the tread 11 and hold-down part 12. The end of the leg 14 "is arched to facilitate sliding in the recess 13 '.

In der Fahrtstellung des Fersenhalters berührt die Einheit 13 den Auslösehebel 8 längs einer Trennebene 18. Über diese Trennebene 18 ragen Lageraugen 19 für die Querachse 7, welche am Auslösehebel 8 angesetzt sind, seitlich vor. Weiters weist die Einheit 13 einen Ansatz 20 auf, welcher in der Fahrtstellung des Fersenhalters in eine Aussparung 21 im Auslösehebel 8 unterhalb der beiden Lageraugen 19 einrastet. Dieser Ansatz 20 steht infolgedessen nach der anderen Seite als die beiden Lageraugen 19 über die Trennebene 18 vor. Schließlich sind am Auslösehebel 8 Anschlagflächen 22, 22' vorgesehen, welche einerseits den Schwenkwinkel der Gelenklasche 16 und anderseits jenen der Einheit 13 begrenzen. Dieser beträgt bei der Einheit 13 etwa 36°, bei der Gelenklasche 16 hingegen 72°.In the driving position of the heel holder, the unit 13 touches the release lever 8 along a parting plane 18. Over this parting plane 18, bearing eyes 19 for the transverse axis 7, which are attached to the release lever 8, project laterally. Furthermore, the unit 13 has a shoulder 20 which, in the driving position of the heel holder, engages in a recess 21 in the release lever 8 below the two bearing eyes 19. This approach 20 consequently projects on the other side than the two bearing eyes 19 over the parting plane 18. Finally, 8 stop surfaces 22, 22 'are provided on the release lever, which on the one hand limit the pivoting angle of the joint plate 16 and on the other hand that of the unit 13. This is approximately 36 ° for the unit 13, but 72 ° for the joint plate 16.

Die Funktion des erfindungsgemäßen Fersenhalters ist folgende : In der Fahrtstellung des Fersenhalters wird die Einheit 13 mittels des Vorderbackens der Skibindung gegen die Kraft der Federn 14, 15 fest gegen den Auslösehebel 8 gepreßt, so daß sich beide Teile längs der Trennebene 18 berühren (vgl. Fig. 2). Bei einer willkürlichen Auslösung des Fersenhalters wird der Auslösehebel 8 aus der Fahrtstellung um die Querachse 7 gegen die Skioberseite 1a hin verschwenkt. Dabei gleitet der Rastbolzen 10 entlang der Steuerkurve 9 des Auslösehebels 8, wobei gleichzeitig die Rastfeder 4 im Gehäuse 5 etwas zusammengedrückt wird.The function of the heel holder according to the invention is as follows: in the driving position of the heel holder, the unit 13 is pressed firmly against the release lever 8 by means of the front jaw of the ski binding against the force of the springs 14, 15, so that both parts touch along the parting plane 18 (cf. Fig. 2). If the heel holder is triggered arbitrarily, the release lever 8 is pivoted out of the driving position about the transverse axis 7 against the upper side 1a of the ski. The locking pin 10 slides along the control curve 9 of the release lever 8, the locking spring 4 in the housing 5 being compressed somewhat at the same time.

Ein analoger Vorgang spielt sich bei einer unwillkürlichen Auslösung des Fersenhalters ab, bei der infolge einer vom strichpunktiert angedeuteten. Absatz des Skischuhs auf den Niederhalteteil 12 ausgeübten, nach oben wirkenden Kraft der Auslösehebel 8 in Fig. 2 im Uhrzeigersinn verschwenkt wird, was gleichfalls ein Gleiten des Rastbolzens 10 entlang der Steuerkurve 9 des Auslösehebels 8 und ein Zusammendrücken der Rastfeder 4 im Gehäuse 5 zur Folge hat. Bei beiden Auslösevorgängen bleibt die Einheit 13 solange in Anlage an dem Auslösehebel 8, bis der in Fig.2 mit strichpunktierten Linien angedeutete Skischuh den Fersenhalter verlassen hat. Dies wird durch den Ansatz 20 der Einheit 13 bewerkstelligt, der in die Aussparung 21 des Auslösehebels 8 eingreift.An analogous process occurs when the heel holder is triggered involuntarily, in the consequence of one indicated by the dash-dot line. Heel of the ski boot on the hold-down part 12, upward force of the release lever 8 is pivoted clockwise in FIG Has. In both release processes, the unit 13 remains in contact with the release lever 8 until the ski boot indicated by dash-dotted lines in FIG. 2 has left the heel holder. This is accomplished by the extension 20 of the unit 13, which engages in the recess 21 of the release lever 8.

Löst bei der Fahrt jedoch nur der in der Zeichnung nicht dargestellte Vorderbacken der Skibindung aus, und verläßt der Skischuh die Skibindung, so wird die Einheit 13 unter dem Einfluß der beiden. Schenkelfedern 14 in Fig. 3 im Ührzeigersinn verschwenkt. Gleichzeitig wird die Einheit 13 infolge der Druckfeder 15 auch von der Trennebene 18 weggedrückt, was erst das Verschwenken möglich macht. Dieses Wegdrücken der Einheit 13 kommt dadurch zustande, daß die Druckfeder 15, die auf das im Auslösehebel 8 gelagerte Ende der Gelenklasche 16 wirkt, letztere infolge ihres Langloches 16' in Richtung zur Skispitze hin verschiebt. Es erhält demnach die Einheit 13 eine aus einer Rotation und einer Translation zusammengesetzte Bewegung, welche durch die Anschlagflächen 22 und 22' am Auslösehebel begrenzt wird. Auf diese Weise ist es möglich, auch nach einem Auslösen des Vorderbackens allein in die Skibindung mit dem Skischuh wieder einzusteigen, ohne daß zuvor der Auslösehebel 8 von Hand verschwenkt werden muß.If, however, only the toe of the ski binding, not shown in the drawing, triggers during the journey and the ski boot leaves the ski binding, the unit 13 becomes under the influence of the two. Leg springs 14 pivoted clockwise in FIG. 3. At the same time, the unit 13 is also pushed away from the parting plane 18 as a result of the compression spring 15, which only makes pivoting possible. This pushing away of the unit 13 comes about because the compression spring 15, which acts on the end of the articulated bracket 16 mounted in the release lever 8, shifts the latter due to its elongated hole 16 'towards the ski tip. Accordingly, the unit 13 receives a movement composed of a rotation and a translation, which is limited by the stop surfaces 22 and 22 'on the release lever. In this way it is possible, even after the toe piece has been released, to re-enter the ski binding with the ski boot alone without the release lever 8 having to be pivoted by hand beforehand.

Selbstverständlich ist die Erfindung keineswegs an das in der Zeichnung dargestellte und im vorstehenden beschriebene Ausführungsbeispiel gebunden. Beispielsweise könnte man anstelle einer Schraubendruckfeder auch ein Tellerfedernpaket in der bzw. in jeder Sackbohrung des Auslösehebels unterbringen.Of course, the invention is in no way tied to the exemplary embodiment shown in the drawing and described above. For example, instead of a helical compression spring, a set of disc springs could also be accommodated in or in each blind hole of the release lever.
