Definitions

  • the invention relates to a safety ski binding with a heel shoe according to the preamble of claim 1.
  • Such a safety ski binding is known from CH-PS 417 433.
  • the manual opening lever is pressed down against the biasing force of the release spring, whereby the locking projection is brought out of the swivel range of the culmination point of the slide track and the sole holder can be swung up force-free.
  • This arbitrary pivoting of the sole holder into the open position can be brought about either by lifting the heel region of the ski boot or, if the ski boot is not in engagement with the ski binding, by hand.
  • the invention has for its object to provide a heel shoe for a safety ski binding, in which the sole holder can be pivoted securely into its open position despite simple and inexpensive construction.
  • the hand opening lever hurries during the opening movement to the sole holder that is still in the closed position until the actuation stop and the counter stop come into engagement, whereupon the sole holder also swivels in the opening direction, in fact faster than the hand opening lever in that the culmination point changes Locking projection approaches more and more until the locking projection engages again with the slide track shortly before reaching the culmination point.
  • the further pivoting movement of the hand opening lever would be blocked by the stops acting between the hand opening lever and the sole holder if these or at least one of them were not designed to be resilient.
  • An advantageous embodiment of the invention is characterized in that the distance between the first transverse axis and the culmination point is 1.5 to 4 times, preferably 2 to 3 times and in particular 2.5 times the distance between the point of engagement of the actuation stop and the first transverse axis. With such a dimensioning of the distances, particularly favorable force and speed relationships exist between the sole holder and the hand opening lever.

  • This pushing spring 26 supports the bearing housing to the rear and, when the ski boot is inserted into the ski binding, causes an axial pushing force on the ski boot sole in the direction of a toe piece, not shown. Due to the resilient support of the heel shoe in the axial direction, it is possible to compensate for a change in the distance between the heel shoe and the toe shoe, which can occur when the ski bends, for example when driving through floor recesses.

  • the hand opening lever 15 is made in one piece and consists of a lower bearing area 35 which is the second transverse axis 14 receives, a middle power transmission area 36 and an upper, slightly angled depressing area 37.
  • the hand opening lever 15 has a locking projection 17 directed towards the front jaw, which engages in the closed position of the sole holder 13 in the first locking recess 18 of the sliding track 20 to exert a hold-down force holding the ski boot on the ski on the sole holder 13.
  • the force holding the sole holder 13 in its closed and open position is generated by the release spring 16, which is arranged in an axial central opening 38 of the bearing housing 11.
  • the trigger spring 16 rests with its rear end against an adjusting disk 39 which is supported on the rear of the bearing housing 11 and can be displaced in the axial direction by means of an adjusting screw 40 in order to be able to set the required pretension.

  • the release spring 16 generates a clockwise torque about the second transverse axis 14, which is transmitted to the sole holder 13 via the locking projection 17 and acts on the sole holder 13 in the direction of its closed position.
  • a resilient counter stop 23 is fastened at the bottom in such a way that when the hand opening lever 15 is pivoted in the direction of the arrow 42 and in the closed position sole holder 13 on the actuating stop 22 at the engagement point 24 for engagement is coming.
  • the manual opening lever 15 In the closed position, the manual opening lever 15 is in its foremost position under the action of the release spring 16, in which the latching projection 17 is pressed into the first latching recess 18 of the slide track 20 and thus holds the sole holder 13 in the closed position.
  • the latching projection 17 initially moves away from the first latching recess 8 and also lifts off from the upper section and the horizontal sliding section 32 of the sliding track 20.
  • the sole holder 13 is decoupled from the biasing force of the release spring 16, but remains in the closed position due to its weight.
  • the horizontal sliding section 32 moves upward much faster than the latching projection 17, so that the horizontal sliding section 32 of the sole holder 13 approaches the latching projection 17 again.
  • the culmination point 21 located at the end of the horizontal sliding section 32 is arranged at a distance B from the first transverse axis 12 which is approximately 2.5 times the distance A between the point of engagement 24 of the actuating stop 22 with the Counter stop 23 and the first transverse axis 12 is.

  • the sole holder 13 When the hand opening lever 15 swings slightly, the sole holder 13 jumps into an over-center position, in which the latching projection 17 engages with the vertical sliding section 33. In this position, a further actuation of the hand opening lever 15 is no longer necessary, since the actuation stop 22 and thus the entire sole holder 13 is pivoted further about the first transverse axis 12 due to the relaxation of the resilient counter-stop 23.
  • the release spring 16 presses the locking projection 17 against the vertical sliding section 33, which likewise exerts a force in the vertical direction and thus a torque about the first transverse axis 12 in the counterclockwise direction, which pivots the sole holder 13 into its open position.

  • the locking projection 17 of the hand opening lever 15 when the counter stop 23 or the actuating stop 22 is not compressed lies in the pivoting range of the horizontal sliding section 32 of the sliding track 20, as a result of which the further pivoting movement of the hand opening lever 15 and the sole holder 13 into the open position is initially blocked while the locking projection 17 can be brought out of the swivel range of the horizontal sliding section 32 by compressing the resilient stop above the culmination point, so that the locking projection 17 can slide into the dead center position of the slide track 20.
  • the pressure force of the resilient stop 23 and then the thrust force of the release spring 16 after the hand release lever 15 is released causes the further rotary movement of the sole holder 13 into its open position.

  • the hand opening lever 15 is also biased via the cross pin 44 and the slot guide 45 into its closed position, in which it is its steepest, i.e. occupies the most upward position.

Abstract

PCT No. PCT/EP89/00922 Sec. 371 Date Mar. 26, 1990 Sec. 102(e) Date Mar. 26, 1990 PCT Filed Aug. 3, 1989 PCT Pub. No. WO90/01358 PCT Pub. Date Feb. 22, 1990.In a safety ski binding with a heel unit which includes a bearing housing (11), a sole holder (13), a hand opening lever (15) and a release spring (16), an actuating abutment (22) is arranged on the sole holder (13) at a distance (A) from the first transverse axle (12) which is substantially smaller than the distance (B) of the culmination point from the first transverse axle (12). Moreover, a counter-abutment (23) which cooperates with the actuating abutment (22) is provided on the hand opening lever (15), with one of the two abutments (22, 23) being made resiliently yielding. Through cooperation of the two abutments (22, 23) the sole holder (13) pivots at a higher speed than the hand opening lever (15) into its open position. As a result the horizontal sliding section (32) enters into engagement again with the latch projection (17) shortly before reaching the culmination point (21), so that the further pivoting is only possible under compression of the resilient abutment. After exceeding the culmination point (21) the resilient abutment, together with the release spring (16), brings about the full opening of the sole holder (13).

Description

Die Erfindung betrifft eine Sicherheitsskibindung mit einem Fersenbacken nach dem Oberbegriff des Patentanspruches 1.The invention relates to a safety ski binding with a heel shoe according to the preamble of claim 1.

Eine derartige Sicherheitsskibindung ist aus der CH-PS 417 433 bekannt. Um diesen bekannten Fersenbacken von Hand von seiner Schließ- in seine Öffnungssstellung zu bewegen, wird der Handöffnungshebel entgegen der Vorspannkraft der Auslösefeder nach unten gedrückt, wodurch der Rastvorsprung aus dem Schwenkbereich des Kulminationspunktes der Kulissenbahn gebracht wird und der Sohlenhalter kraftfrei nach oben geschwenkt werden kann. Dieses willkürliche Schwenken des Sohlenhalters in die Öffnungsstellung kann entweder durch ein Hochheben des Fersenbereichs des Skischuhs oder, wenn sich der Skischuh nicht in Eingriff mit der Skibindung befindet, von Hand bewirkt werden. Um das willkürliche Hochschwenken des Sohlenhalters in seine Öffnungsstellung zu erleichtern, ist es außerdem bekannt, eine zusätzliche Öffnungsfeder vorzusehen, die am Sohlenhalter angreift und eine geringe Vorspannkraft in Richtung seiner Öffnungsstellung ausübt.Such a safety ski binding is known from CH-PS 417 433. In order to move this known heel cheek by hand from its closed to its open position, the manual opening lever is pressed down against the biasing force of the release spring, whereby the locking projection is brought out of the swivel range of the culmination point of the slide track and the sole holder can be swung up force-free. This arbitrary pivoting of the sole holder into the open position can be brought about either by lifting the heel region of the ski boot or, if the ski boot is not in engagement with the ski binding, by hand. In order to facilitate the arbitrary swiveling up of the sole holder into its open position, it is also known to provide an additional opening spring which acts on the sole holder and exerts a slight pretensioning force in the direction of its open position.

Dabei erweist es sich als nachteilig, daß in Form der Öffnungsfeder ein zusätzliches Bauteil erforderlich ist, das auch zusätzliche Montagekosten erfordert und gegen Korrosion empfindlich ist.It proves to be disadvantageous that an additional component is required in the form of the opening spring, which also requires additional assembly costs and is sensitive to corrosion.

Der Erfindung liegt die Aufgabe zugrunde, einen Fersenbacken für eine Sicherheitsskibindung zu schaffen, bei der trotz einfachen und kostengünstigen Aufbaus der Sohlenhalter sicher in seine Öffnungsstellung geschwenkt werden kann.The invention has for its object to provide a heel shoe for a safety ski binding, in which the sole holder can be pivoted securely into its open position despite simple and inexpensive construction.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Aufgrund dieser Ausbildung eilt der Handöffnungshebel bei der Öffnungsbewegung zunächst dem noch in der Schließstellung verbleibenden Sohlenhalter vor, bis der Betätigungsanschlag und der Gegenanschlag in Eingriff kommen, worauf auch der Sohlenhalter in Öffnungsrichtung schwenkt, und zwar insofern schneller als der Handöffnungshebel, als sich der Kulminationspunkt dem Rastvorsprung immer mehr annähert, bis der Rastvorsprung erneut mit der Kulissenbahn kurz vor erreichen des Kulminationspunktes in Eingriff tritt. Jetzt würde die weitere Schwenkbewegung des Handöffnungshebels durch die zwischen dem Handöffnungshebel und dem Sohlenhalter wirkenden Anschläge blockiert, wenn diese oder wenigstens einer von ihnen nicht federnd ausgebildet wären. Das Weiterschwenken des Handöffnungshebels bis zum Gleiten des Rastvorsprunges über den Kulminationspunkt ist jedoch unter Zusammendrücken der federnden Anschläge möglich, wodurch eine zusätzliche Vorspannkraft erzeugt wird, die direkt auf den Sohlenhalter einwirkt und ein Drehmoment in Richtung seiner Öffnungsstellung bewirkt. Sobald der Rastvorsprung den Kulminationspunkt überschritten hat, entspannen sich die federnden Anschläge bzw. der federnde Anschlag und der Sohlenhalter schnappt beim Loslassen des Handöffnungshebels in seine Offenstellung.Due to this design, the hand opening lever hurries during the opening movement to the sole holder that is still in the closed position until the actuation stop and the counter stop come into engagement, whereupon the sole holder also swivels in the opening direction, in fact faster than the hand opening lever in that the culmination point changes Locking projection approaches more and more until the locking projection engages again with the slide track shortly before reaching the culmination point. Now the further pivoting movement of the hand opening lever would be blocked by the stops acting between the hand opening lever and the sole holder if these or at least one of them were not designed to be resilient. The pivoting of the hand opening lever until the locking projection slides over the culmination point is possible, however, by compressing the resilient stops, which creates an additional pretensioning force which acts directly on the sole holder and causes a torque in the direction of its opening position. As soon as the locking projection has exceeded the culmination point, the resilient stops or the resilient stop relax and the sole holder snaps into its open position when the hand opening lever is released.

Auf diese Weise ist keine zusätzliche Öffnungsfeder zwischen dem Gehäuse und dem Sohlenhalter erforderlich, wodurch der Fersenbacken einfacher und kostengünstiger hergestellt werden kann. Außerdem wirkt in der Schließstellung des Sohlenhalters vorteilhafterweise keine - wenn auch geringe - Federkraft in Richtung der Öffnungsstellung, so daß die Vorspannkraft der Auslösefeder nicht verfälscht wird.In this way, no additional opening spring between the housing and the sole holder is required, which makes the heel shoe easier and cheaper to manufacture can. In addition, in the closed position of the sole holder advantageously no spring force acts, albeit slightly, in the direction of the open position, so that the pretensioning force of the release spring is not falsified.

Eine vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß der Abstand zwischen der ersten Querachse und dem Kulminationspunkt das 1,5 bis 4-fache, vorzugsweise das 2 bis 3-fache und insbesondere das 2, 5-fache des Abstands zwischen dem Eingriffspunkt des Betätigungsanschlags und der ersten Querachse beträgt. Bei einer derartigen Bemessung der Abstände sind besonders günstige Kraft- und Geschwindigkeitsverhältnisse zwischen dem Sohlenhalter und dem Handöffnungshebel gegeben.An advantageous embodiment of the invention is characterized in that the distance between the first transverse axis and the culmination point is 1.5 to 4 times, preferably 2 to 3 times and in particular 2.5 times the distance between the point of engagement of the actuation stop and the first transverse axis. With such a dimensioning of the distances, particularly favorable force and speed relationships exist between the sole holder and the hand opening lever.

Weitere vorteilhafte Ausführungsformen der Erfindung sind aus den Unteransprüchen ersichtlich.Further advantageous embodiments of the invention are evident from the subclaims.

Die Erfindung wird nachfolgend beispielsweise anhand der Zeichnung näher erläutert. In dieser zeigt:

  • Figur 1 eine teilweise geschnittene Seitenansicht eines Fersenbackens in der Schließstellung,
  • Figur 2 eine Seitenansicht des Fersenbackens in einer halb geöffneten Stellung kurz vor Erreichen des Kulminationspunktes und
  • Figur 3 eine Seitenansicht des Fersenbackens in der Öffnungsstellung,
  • Figur 4 eine schematische Seitenansicht einer zweiten Ausführungsform des Fersenbackens in einer halb geöffneten Stellung kurz vor Erreichen des Kulminationspunktes.
The invention is explained in more detail below, for example with reference to the drawing. In this shows:
  • FIG. 1 shows a partially sectioned side view of a heel shoe in the closed position,
  • Figure 2 is a side view of the heel cheek in a half-open position just before reaching the culmination point and
  • FIG. 3 shows a side view of the heel cheek in the open position,
  • Figure 4 is a schematic side view of a second embodiment of the heel cheek in a half-open position shortly before reaching the culmination point.

Figur 1 zeigt einen Fersenbacken, der ein Lagergehäuse 11, einen Sohlenhalter 13, einen Handöffnungshebel 15 und eine Auslösefeder 16 umfaßt.FIG. 1 shows a heel shoe which comprises a bearing housing 11, a sole holder 13, a hand opening lever 15 and a release spring 16.

Das Lagergehäuse 11 ist längsverschieblich auf einer Grundplatte 25 befestigt, die fest auf der Oberfläche eines nicht dargestellten Skis angeordnet ist. Am Lagergehäuse 11 greift in axialer Richtung eine Anschubfeder 26 mit einem Ende an, während ihr anderes Ende an einem auf der Grundplatte 25 befestigten Axialanschlag 27 anliegt. Diese Anschubfeder 26 stützt das Lagergehäuse nach hinten ab und bewirkt beim Einsetzen des Skischuhs in die Skibindung eine axiale Anschubkraft auf die Skischuhsohle in Richtung eines nicht dargestellten Vorderbackens. Durch die in axialer Richtung federnde Abstützung des Fersenbackens ist es möglich, eine Änderung des Abstandes zwischen dem Fersen- und dem Vorderbacken auszugleichen, die bei einer Durchbeigung des Skis beispielsweise beim Durchfahren von Bodenmulden auftreten kann.The bearing housing 11 is fastened in a longitudinally displaceable manner on a base plate 25 which is fixedly arranged on the surface of a ski, not shown. A thrust spring 26 engages one end of the bearing housing 11 in the axial direction, while its other end abuts an axial stop 27 fastened to the base plate 25. This pushing spring 26 supports the bearing housing to the rear and, when the ski boot is inserted into the ski binding, causes an axial pushing force on the ski boot sole in the direction of a toe piece, not shown. Due to the resilient support of the heel shoe in the axial direction, it is possible to compensate for a change in the distance between the heel shoe and the toe shoe, which can occur when the ski bends, for example when driving through floor recesses.

Im oberen Bereich des Lagergehäuses 11 ist senkrecht zur Längsrichtung des Skis eine horizontale erste Querachse 12 angeordnet, um die der Sohlenhalter 13 schwenkbar gelagert ist. Diese erste Querachse 12 ist nahe dem hinteren Ende des Sohlenhalters 13 vorgesehen.In the upper area of the bearing housing 11, a horizontal first transverse axis 12 is arranged perpendicular to the longitudinal direction of the ski, about which the sole holder 13 is pivotably mounted. This first transverse axis 12 is provided near the rear end of the sole holder 13.

Der Sohlenhalter 13 weist an seinem vorderen, dem Vorderbacken zugewandten Ende oben einen Sohlenniederhalter 28, unten einen Trittsporn 29 und dazwischen eine vordere Abschlußwand 30 auf, die mit dem Fersenteil der nicht dargestellten Skischuhsohle zusammenwirken. Die Skischuhsohle liegt bei eingesetztem Skischuh auf einer Trittplatte 10 auf, die auf der Grundplatte 25 befestigt ist.The sole holder 13 has at its front end facing the front jaw a sole hold-down 28 at the bottom, a step spur 29 and in between a front end wall 30 which cooperate with the heel part of the ski shoe sole, not shown. When the ski boot is inserted, the sole of the ski lies on a tread plate 10 which is fastened on the base plate 25.

Auf der der ersten Querachse 12 zugewandten Seite der Abschlußwand 30 ist eine Kulissenbahn 20 mit einem im wesentlichen vertikalen Oberabschnitt 31, einem Horizontalgleitabschnitt 32, einem Vertikalgleitabschnitt 33 und einem im wesentlichen horizontalen Unterabschnitt 34 vorgesehen. Zwischen dem Oberabschnitt 31 und dem Horizontalgleitabschnitt 32 befindet sich eine erste Rastvertiefung 18 und zwischen dem Vertikalgleitabschnitt 33 und dem Unterabschnitt 34 eine zweite Rastvertiefung 19, während am Übergang des Horizontalgleitabschnitts 32 in den Vertikalgleitabschnitt 33 ein zur ersten Querachse 12 gerichteter, knieartiger Vorsprung ausgebildet ist, der einen Kulminationspunkt 21 aufweist.On the side of the end wall 30 facing the first transverse axis 12, a sliding track 20 with an essentially vertical upper section 31, a horizontal sliding section 32, a vertical sliding section 33 and an essentially horizontal lower section 34 is provided. Between the upper section 31 and the horizontal sliding section 32 there is a first latching recess 18 and between the vertical sliding section 33 and the lower section 34 a second latching recess 19, while at the transition of the horizontal sliding section 32 into the vertical sliding section 33 a knee-like projection directed towards the first transverse axis 12 is formed, which has a culmination point 21.

Oberhalb und geringfügig hinter der ersten Querachse 12 weist der Sohlenhalter 13 einen nockenförmigen Betätigungsanschlag 22 auf, der den Sohlenhalter 13 nach oben überragt und mit diesem einstückig ausgebildet ist.Above and slightly behind the first transverse axis 12, the sole holder 13 has a cam-shaped actuation stop 22 which projects above the sole holder 13 and is formed in one piece with it.

Der Handöffnungshebel 15 ist über eine zweite Querachse 14, die zur ersten Querachse 12 parallel verläuft, mit dem Lagergehäuse 11 verbunden und auf dieser drehbar gelagert. Diese zweite Querachse 14 befindet sich im grundplattennahen Bereich des Lagergehäuses 11 und liegt in axialer Richtung etwa in der Mitte zwischen der ersten Querachse 12 und der ersten Rastvertiefung 18. Der Handöffnungshebel 15 ist einteilig ausgeführt und besteht aus einem unteren Lagerbereich 35, der die zweite Querachse 14 aufnimmt, einem mittleren Kraftübertragungsbereich 36 und einem oberen, geringfügig nach hinten abgewinkelten Niederdrückbereich 37. Im Kraftübertragungsbereich 36 weist der Handöffnungshebel 15 einen zum Vorderbacken hin gerichteten Rastvorsprung 17 auf, der in der Schließstellung des Sohlenhalters 13 in die erste Rastvertiefung 18 der Kulissenbahn 20 einrastet, um auf den Sohlenhalter 13 eine den Skischuh auf dem Ski haltende Niederhaltekraft auszuüben.The hand opening lever 15 is connected to the bearing housing 11 via a second transverse axis 14, which runs parallel to the first transverse axis 12, and is rotatably supported thereon. This second transverse axis 14 is located in the area of the bearing housing 11 near the base plate and lies in the axial direction approximately in the middle between the first transverse axis 12 and the first latching recess 18. The hand opening lever 15 is made in one piece and consists of a lower bearing area 35 which is the second transverse axis 14 receives, a middle power transmission area 36 and an upper, slightly angled depressing area 37. In the power transmission area 36, the hand opening lever 15 has a locking projection 17 directed towards the front jaw, which engages in the closed position of the sole holder 13 in the first locking recess 18 of the sliding track 20 to exert a hold-down force holding the ski boot on the ski on the sole holder 13.

Die den Sohlenhalter 13 in seiner Schließ- und Öffnungsstellung haltende Kraft wird durch die Auslösefeder 16 erzeugt, die in einer axialen Zentralöffnung 38 des Lagergehäuses 11 angeordnet ist. Die Auslösefeder 16 liegt mit ihrem hinteren Ende an einer hinten am Lagergehäuse 11 abgestützten Einstellscheibe 39 an, die mittels einer Einstellschraube 40 in axialer Richtung verschiebbar ist, um die erforderliche Vorspannung einstellen zu können. Mit dem vorderen Ende liegt die Auslösefeder 16 an einer hinteren halbkugelförmigen Nocke 41 des Handöffnungshebels 15 an, der im wesentlichen auf gleicher Höhe wie der Rastvorsprung 17 angeordnet ist. So erzeugt die Auslösefeder 16 ein im Uhrzeigersinn wirkendes Drehmoment um die zweite Querachse 14, das über den Rastvorsprung 17 auf den Sohlenhalter 13 übertragen wird und diesen in Richtung seiner Schließstellung beaufschlagt.The force holding the sole holder 13 in its closed and open position is generated by the release spring 16, which is arranged in an axial central opening 38 of the bearing housing 11. The trigger spring 16 rests with its rear end against an adjusting disk 39 which is supported on the rear of the bearing housing 11 and can be displaced in the axial direction by means of an adjusting screw 40 in order to be able to set the required pretension. With the front end, the release spring 16 bears against a rear hemispherical cam 41 of the hand opening lever 15, which is arranged essentially at the same height as the latching projection 17. Thus, the release spring 16 generates a clockwise torque about the second transverse axis 14, which is transmitted to the sole holder 13 via the locking projection 17 and acts on the sole holder 13 in the direction of its closed position.

Im bei einer Öffnungsbewegung sich nach unten bewegenden Betätigungsbereich 37 des Handöffnungshebels 15 ist unten ein federnder Gegenanschlag 23 so befestigt, daß er beim Schwenken des Handöffnungshebels 15 in Richtung des Pfeiles 42 und in der Schließstellung verbleibendem Sohlenhalter 13 an dem Betätigungsanschlag 22 im Eingriffspunkt 24 zur Anlage kommt.In the actuating region 37 of the hand opening lever 15 moving downward during an opening movement, a resilient counter stop 23 is fastened at the bottom in such a way that when the hand opening lever 15 is pivoted in the direction of the arrow 42 and in the closed position sole holder 13 on the actuating stop 22 at the engagement point 24 for engagement is coming.

Im folgenden wird der Funktionsablauf beim manuellen Öffnen des Fersenbackens aus seiner Schließstellung beschrieben:The following describes the functional sequence when manually opening the heel shoe from its closed position:

In der Schließstellung befindet sich der Handöffnungshebel 15 unter Einwirkung der Auslösefeder 16 in seiner vordersten Stellung, in der der Rastvorsprung 17 in die erste Rastvertiefung 18 der Kulissenbahn 20 hineingedrückt wird und damit den Sohlenhalter 13 in der Schließstellung hält.In the closed position, the manual opening lever 15 is in its foremost position under the action of the release spring 16, in which the latching projection 17 is pressed into the first latching recess 18 of the slide track 20 and thus holds the sole holder 13 in the closed position.

Wird nun der Handöffnungshebel 15 in Richtung des Pfeils 42 unter Zusammendrückung der Auslösefeder 16 bis zum Betätigungsanschlag 22 geschwenkt, so entfernt sich der Rastvorsprung 17 zunächst von der ersten Rastvertiefung 8 und hebt auch von dem Oberabschnitt und dem Horizontalgleitabschnitt 32 der Kulissenbahn 20 ab. In diesem Zustand ist der Sohlenhalter 13 von der Vorspannkraft der Auslösefeder 16 abgekoppelt, bleibt aber wegen seines Gewichtes in der Schließlage.If the hand opening lever 15 is now pivoted in the direction of arrow 42 with compression of the release spring 16 up to the actuation stop 22, the latching projection 17 initially moves away from the first latching recess 8 and also lifts off from the upper section and the horizontal sliding section 32 of the sliding track 20. In this state, the sole holder 13 is decoupled from the biasing force of the release spring 16, but remains in the closed position due to its weight.

Beim weiteren Niederschwenken des Handöffnungshebels 15 in seine Öffnungsstellung ist der Gegenanschlag 23 mit dem Betätigungsanschlag 22 in Eingriff und übt auf diesen eine Kraft in Richtung des Pfeils 42 aus, wodurch der Betätigungsanschlag 22 nach hinten und damit der Sohlenhalter 13 um die erste Querachse 12 nach oben geschwenkt wird. Da der Abstand A des Eingriffspunktes 24 von der Querachse 12 wesentlich kleiner als der Abstand B der Querachse 12 vom Kulminationspunkt 21 bzw. als der Abstand der Querachse 12 von der Rastvertiefung 18 ist und sich der Rastvorsprung 17 bereits in einem zenitnahen Bereich seines Schwenkkreises um die zweite Querachse 14 befindet, bewegt sich der Horizontalgleitabschnitt 32 wesentlich schneller nach oben als der Rastvorsprung 17, so daß der Horizontalgleitabschnitt 32 des Sohlenhalters 13 dem Rastvorsprung 17 wieder nähert.When the hand opening lever 15 is pivoted further down into its open position, the counter stop 23 engages with the actuating stop 22 and exerts a force thereon in the direction of the arrow 42, as a result of which the actuating stop 22 moves rearward and thus the sole holder 13 about the first transverse axis 12 upwards is pivoted. Since the distance A of the point of engagement 24 from the transverse axis 12 is significantly smaller than the distance B of the transverse axis 12 from the culmination point 21 or as the distance of the transverse axis 12 from the locking recess 18 and the locking projection 17 is already in a zenith-near area of its swivel circle around the second transverse axis 14, the horizontal sliding section 32 moves upward much faster than the latching projection 17, so that the horizontal sliding section 32 of the sole holder 13 approaches the latching projection 17 again.

Dieses Annähern wird aber dadurch begünstigt, daß der am Ende des Horizontalgleitabschnitts 32 befindliche Kulminationspunkt 21 in einem Abstand B von der ersten Querachse 12 angeordnet ist, der in etwa das 2,5-fache des Abstands A zwischen dem Eingriffspunkt 24 des Betätigungsanschlags 22 mit dem Gegenanschlag 23 und der ersten Querachse 12 ist. Dadurch legt der Kulminationspunkt 21 bei gleicher Winkeländerung eine wesentlich größere Strecke auf seinem Schwenkkreis um die erste Querachse 12, nämlich die 2,5-fache, als der Eingriffspunkt 24 zurück. Da die weiteren Punkte des Horizontalgleitabschnitts 32 von der ersten Querachse 12 noch weiter entfernt sind, gilt dies in noch stärkerem Maße für alle übrigen Punkte auf dem Horizontalgleitabschnitt 32.This approach is favored by the fact that the culmination point 21 located at the end of the horizontal sliding section 32 is arranged at a distance B from the first transverse axis 12 which is approximately 2.5 times the distance A between the point of engagement 24 of the actuating stop 22 with the Counter stop 23 and the first transverse axis 12 is. As a result, the culmination point 21 travels a substantially greater distance on its swivel circle about the first transverse axis 12, namely 2.5 times, than the engagement point 24 with the same change in angle. As the other points of the horizontal sliding section 32 are still further away from the first transverse axis 12, this applies even more to all other points on the horizontal sliding section 32.

Am Ende dieser Näherungsphase gelangt der Horizontalgleitabschnitt 32 kurz vor dem Kulminationspunkt 21 wieder mit dem Rastvorsprung 17 in Eingriff. Ein weiteres Schwenken des Handöffnungshebels 15 ist nun nur dadurch möglich, daß der federnde Gegenanschlag 23 zusammengedrückt wird, wie aus Figur 2 ersichtlich ist. Die Auslösefeder 16 wird solange zusammengedrückt, bis der Rastvorsprung 17 den Kulminationspunkt 21 und damit seine Totlage erreicht, in der beim Loslassen des Handöffnungshebels 15 der Sohlenhalter 13 weder in seine Schließ-, noch in seine Öffnungsstellung schwenken würde.At the end of this approximation phase, the horizontal sliding section 32 engages with the locking projection 17 shortly before the culmination point 21. A further pivoting of the hand opening lever 15 is now only possible by compressing the resilient counter stop 23, as can be seen from FIG. 2. The trigger spring 16 is compressed until the latching projection 17 reaches the culmination point 21 and thus its dead position, in which the sole holder 13 would not pivot into its closed or open position when the hand opening lever 15 was released.

Bei einem geringfügigen Weiterschwenken des Handöffnungshebels 15 springt der Sohlenhalter 13 in eine Übertotpunktlage, in der der Rastvorsprung 17 mit dem Vertikalgleitabschnitt 33 in Eingriff tritt. In dieser Lage ist eine weitere Betätigung des Handöffnungshebels 15 nicht mehr erforderlich, da durch die nunmehr erfolgende Entspannung des federnden Gegenanschlags 23 der Betätigungsanschlag 22 und damit der gesamte Sohlenhalter 13 um die erste Querachse 12 weitergeschwenkt wird. Die Auslösefeder 16 drückt dabei den Rastvorsprung 17 gegen den Vertikalgleitabschnitt 33, wodurch ebenfalls eine Kraft in vertikaler Richtung und damit ein Drehmoment um die erste Querachse 12 im Gegenuhrzeigersinn ausgeübt wird, die dem Sohlenhalter 13 in seine Öffnungsstellung schwenkt.When the hand opening lever 15 swings slightly, the sole holder 13 jumps into an over-center position, in which the latching projection 17 engages with the vertical sliding section 33. In this position, a further actuation of the hand opening lever 15 is no longer necessary, since the actuation stop 22 and thus the entire sole holder 13 is pivoted further about the first transverse axis 12 due to the relaxation of the resilient counter-stop 23. The release spring 16 presses the locking projection 17 against the vertical sliding section 33, which likewise exerts a force in the vertical direction and thus a torque about the first transverse axis 12 in the counterclockwise direction, which pivots the sole holder 13 into its open position.

Die Öffnungsstellung ist aus der Figur 3 ersichtlich. In dieser greift der Rastvorsprung 17 in die zweite Rastvertiefung 19 der Kulissenbahn 20 ein, so daß der Sohlenhalter 13 in der Öffnungsstellung verrastet ist. Der federnde Gegenanschlag 23 ist in dieser Lage wieder entspannt.The open position can be seen from FIG. 3. In this, the locking projection 17 engages in the second recess 19 of the slide 20, so that the sole holder 13 is locked in the open position. The resilient counterstop 23 is relaxed again in this position.

Das automatische Öffnen des Fersenbackens bei einem Sturz geschieht im wesentlichen in der gleichen Weise wie bei der Handauslösung. Im Unterschied zu der Handauslösung wird die Kraft zum Schwenken des Handöffnungshebels 15 bis zum Erreichen der Übertotpunktlage nicht über den Niederdrückbereich 37 des Handöffnungshebels 15 eingebracht, sondern über den Horizontalgleitabschnitt 32 der Kulissenbahn 20, der den Rastvorsprung 17 des Handöffnungshebels 15 nach oben drückt.The automatic opening of the heel cheek in the event of a fall is essentially the same as for the manual release. In contrast to the manual release, the force for pivoting the hand opening lever 15 until the over-center position is reached is not introduced via the depressing area 37 of the hand opening lever 15, but via the horizontal sliding section 32 of the sliding track 20, which presses the latching projection 17 of the hand opening lever 15 upwards.

Aufgrund dieser geänderten Krafteinleitung hebt der Rastvorsprung 17 in der ersten Phase der Schwenkbewegung nicht von dem Horizontalgleitabschnitt 32 ab, sondern gleitet auf diesem bis zum Kulminationspunkt 21.Because of this changed introduction of force, the locking projection 17 does not lift off the horizontal sliding section 32 in the first phase of the pivoting movement, but slides thereon to the culmination point 21.

Das weitere Öffnen geschieht dann in der gleichen Weise wie bei der Handauslösung.The further opening then takes place in the same way as with the manual release.

Anstelle des Gegenanschlags 23 kann auch der Betätigungsanschlag 22 federnd ausgebildet sein. Die federnden Anschläge können aus Gummi oder einem anderen Material bestehen, das die geforderten elastischen Eigenschaften aufweist. Insbesondere kann anstelle eines Gummielementes auch eine Druckfeder vorgesehen werden.Instead of the counter stop 23, the actuating stop 22 can also be designed to be resilient. The resilient stops can be made of rubber or another material that has the required elastic properties. In particular, a compression spring can also be provided instead of a rubber element.

Maßgebend ist, daß der Rastvorsprung 17 des Handöffnungshebels 15 bei nicht zusammengedrücktem Gegenanschlag 23 bzw. Betätigungsanschlag 22 im schwenkbereich des Horizontalgleitabschnitts 32 der Kulissenbahn 20 liegt, wodurch die weitere Schwenkbewegung des Handöffnungshebels 15 und des Sohlenhalters 13 in die Öffnungsstellung zunächst blockiert ist, während der Rastvorsprung 17 durch Zusammendrücken des federnden Anschlags über den Kulminationspunkt aus dem Schwenkbereich des Horizontalgleitabschnitts 32 bringbar ist, so daß der Rastvorsprung 17 in die Übertotpunktlage der Kulissenbahn 20 gleiten kann. In dieser Lage bewirkt zunächst die Druckkraft des federnden Anschlags 23 und dann die Schubkraft der Auslösefeder 16 nach dem Loslassen des Handöffnungshebels 15 die weitere Drehbewegung des Sohlenhalters 13 in seine Öffnungsstellung.It is important that the locking projection 17 of the hand opening lever 15 when the counter stop 23 or the actuating stop 22 is not compressed lies in the pivoting range of the horizontal sliding section 32 of the sliding track 20, as a result of which the further pivoting movement of the hand opening lever 15 and the sole holder 13 into the open position is initially blocked while the locking projection 17 can be brought out of the swivel range of the horizontal sliding section 32 by compressing the resilient stop above the culmination point, so that the locking projection 17 can slide into the dead center position of the slide track 20. In this position, the pressure force of the resilient stop 23 and then the thrust force of the release spring 16 after the hand release lever 15 is released causes the further rotary movement of the sole holder 13 into its open position.

Damit die Schwenkbewegung des Handöffnungshebels 15 und des Sohlenhalters 13 in die Öffnungsstellung kurz vor dem Kulminationspunkt 21 blockiert werden kann, ist es erforderlich, daß der Horizontalabschnitt 32 der Kulissenbahn 20 mit einer größeren Bahngeschwindigkeit als der Rastvorsprung 17 des Handöffnungshebels 15 in der gleichen Bahnrichtung geschwenkt wird, so daß der vorausgeeilte Rastvorsprung 17 von dem nacheilenden Horizontalgleitabschnitt 32 eingeholt werden und mit diesem wieder in Eingriff treten kann.So that the pivoting movement of the hand opening lever 15 and the sole holder 13 can be blocked in the open position shortly before the culmination point 21, it is necessary that the horizontal section 32 of the sliding track 20 is pivoted in the same path direction at a greater path speed than the locking projection 17 of the hand opening lever 15 , so that the advanced locking projection 17 can be overtaken by the trailing horizontal sliding section 32 and can engage with it again.

Fig. 4 zeigt eine Ausführungsvariante des Fersenbackens, bei der gleiche Teile wie in den Fig. 1 bis 3 mit gleichen Bezugsziffern versehen sind.FIG. 4 shows an embodiment variant of the heel shoe in which the same parts as in FIGS. 1 to 3 are provided with the same reference numbers.

Bei dieser Ausführungsform ist der Rastvorsprung 17 nicht einteilig mit dem Handöffnungshebel 15 ausgebildet, sondern an einem Rastelement 43 vorgesehen, welches innerhalb des Lagergehäuses 11 axial verschiebbar geführt ist.In this embodiment, the locking projection 17 is not formed in one piece with the hand opening lever 15, but is provided on a locking element 43 which is guided axially displaceably within the bearing housing 11.

Das Rastelement 43 weist einen Querzapfen 44 auf, welcher in eine im Handöffnungshebel 15 vorgesehene vertikale Langlochführung 45 eingreift, so daß eine feste und vorherbestimmte Lagebeziehung zwischen der Winkelstellung des Handöffnungshebels 15 und der Lage des Rastelementes 43 besteht. Es können auch mehrere, d.h. an beiden Seiten des Rastelements 43 angeordnete Querzapfen 44 vorgesehen sein, die in entsprechend zugeordnete Langlochführungen 45 des Handöffnungshebels eingreifen. Ferner ist es ebenfalls möglich, den oder die Querzapfen 44 am Handöffnungshebel 15 und die Langlochführung(en) am Rastelement 43 anzuordnen.The locking element 43 has a cross pin 44 which engages in a vertical slot guide 45 provided in the hand opening lever 15, so that there is a fixed and predetermined positional relationship between the angular position of the hand opening lever 15 and the position of the locking element 43. A plurality of cross pins 44, that is to say arranged on both sides of the latching element 43, can also be provided, which engage in correspondingly assigned slot guides 45 of the hand opening lever. Furthermore, it is also possible to use the cross pin or pins 44 on the hand opening lever 15 and the slot guide (s) on the locking element 43.

Die in Fig. 4 nicht dargestellte Auslösefeder ist nicht wie beim Ausführungsbeispiel nach den Fig. 1 bis 3 am Handöffnungshebel 15, sondern am Rastelement 43 abgestützt . Sie liegt mit einem Ende an einer Stirnseite 46 einer Ausnehmung 47 des Rastelementes 43 an, während sich ihr anderes Ende in gleicher Weise wie in den Fig. 1 bis 3 am Lagergehäuse 11 bzw. an der in Fig. 4 nicht dargestellten Einstellscheibe 39 abstützt.The trigger spring, not shown in FIG. 4, is not supported on the manual opening lever 15 as in the exemplary embodiment according to FIGS. 1 to 3, but on the latching element 43. It rests with one end on an end face 46 of a recess 47 of the latching element 43, while its other end is supported in the same way as in FIGS. 1 to 3 on the bearing housing 11 or on the adjusting disk 39 (not shown in FIG. 4).

Das Rastelement 43 wird mittels der Auslösefeder kontinuierlich in Richtung des Pfeiles 48 gedrängt, so daß der einteilig mit dem Rastelement 43 ausgebildete Rastvorsprung 17 den Sohlenhalter 13 in die Schließstellung niederdrückt, wenn sich der Rastvorsprung 17 im Bereich des Horizontalgleitabschnittes 32 befindet. Der Handöffnungshebel 15 ist dabei über den Querzapfen 44 und die Langlochführung 45 ebenfalls in seine Schließstellung vorgespannt, in der er seine steilste, d.h. am weitesten nach oben gerichtete Position einnimmt.The latching element 43 is continuously pushed in the direction of arrow 48 by means of the release spring, so that the latching projection 17, which is formed in one piece with the latching element 43, presses the sole holder 13 into the closed position when the latching projection 17 is in the region of the horizontal sliding section 32. The hand opening lever 15 is also biased via the cross pin 44 and the slot guide 45 into its closed position, in which it is its steepest, i.e. occupies the most upward position.

Die manuelle Überführung des Sohlenhalters 13 von seiner Schließ- in seine Öffnungsstellung über den Handöffnungshebel 15 geschieht in der gleichen Weise wie beim Ausführungsbeispiel gemäß den Fig. 1 bis 3. Der Rastvorsprung 17 kann also nur dadurch von seinem Horizontalgleitabschnitt 32 über den Kulminationspunkt 21 zu seinem Vertikalgleitabschnitt 33 gebracht werden, daß entweder der Betätigungsanschlag 22 oder der Gegenanschlag 23 zusammendrückt wird, wodurch eine weitere Winkelbewegung des Handöffnungshebels 15 und damit eine weitere Horizontalverschiebung des Rastvorsprungs 17 entgegen der Richtung des Pfeils 48 ermöglicht wird.The manual transfer of the sole holder 13 from its closed to its open position via the manual opening lever 15 takes place in the same manner as in the exemplary embodiment according to FIGS. 1 to 3. The latching projection 17 can therefore only move from its horizontal sliding section 32 via the culmination point 21 to it Be brought vertical sliding section 33 that either the actuating stop 22 or the counter-stop 23 is compressed, whereby a further angular movement of the hand opening lever 15 and thus a further horizontal displacement of the locking projection 17 against the direction of arrow 48 is made possible.

Da der Rastvorsprung 17 jedoch nicht am Handöffnungshebel 15, sondern am Rastelement 43 vorgesehen ist, führt der Rastvorsprung 17 im Unterschied zum ersten Ausführungsbeispiel keine Kreisbewegung um die zweite Querachse 14, sondern eine reine Translationsbewegung entgegen der Richtung des Pfeils 48 aus.However, since the locking projection 17 is not provided on the manual opening lever 15, but rather on the locking element 43, the locking projection 17, in contrast to the first exemplary embodiment, does not perform a circular movement about the second transverse axis 14, but a pure translational movement against the direction of the arrow 48.

In der Öffnungsstellung liegt der Rastvorsprung 17 am Vertikalgleitabschnitt 33 der Kulissenbahn 20 an und hält dadurch den Sohlenhalter 13 in der Öffnungsstellung.

In the open position, the locking projection 17 bears against the vertical sliding section 33 of the sliding track 20 and thereby holds the sole holder 13 in the open position.
