Description

Die vorliegende Erfindung bezieht sich auf Absatzhalte­vorrichtungen von Sicherheits-Skibindungen gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to heel holding devices of safety ski bindings according to the preamble of patent claim 1.

Derartige Absatzhaltevorrichtungen sind beispielsweise aus der DE-A-2803647 bekannt. Bei diesen Vorrichtungen ist ein Öffnungshebel vorgesehen, der im Tragteil parallel zum Sohlenhalter gelagert und durch Zug betätig­bar ist. Dabei ist die Anordnung so getroffen, daß der in Öffnungsrichtung des Sohlenhalters hinten liegende Rollkörper zum willkürlichen Öffnen der Vorrichtung vom Öffnungshebel derart beeinflußbar ist, daß sich zunächst eine stärkere Belastung des Sohlenhalters im Sinne des Schließens ergibt.Such heel holding devices are known for example from DE-A-2803647. In these devices, an opening lever is provided which is mounted in the supporting part parallel to the sole holder and can be actuated by train. The arrangement is such that the rolling body located at the rear in the opening direction of the sole holder can be influenced by the opening lever for arbitrary opening of the device in such a way that there is initially a greater load on the sole holder in the sense of closing.

Eine derartige Möglichkeit des willkürlichen Öffnens der Vorrichtung ist jedoch aus verschiedenen Gründen nachteilig. So führt eine Zugbelastung - jedenfalls in der beschriebenen Art - nicht zu einem günstigen Bewe­gungsablauf zum willkürlichen Aussteigen aus der Bin­dung. Außerdem kann nicht ein sofortiges Aufschwenken des Sohlenhalters mit der Betätigung des Öffnungshebels einsetzen.Such a possibility of arbitrarily opening the device is disadvantageous for various reasons. Thus, a tensile load - at least in the manner described - does not lead to a favorable movement sequence for the arbitrary disengagement from the binding. In addition, an immediate swinging open of the sole holder with the actuation of the opening lever cannot begin.

Zweck der vorliegenden Erfindung ist es darum, die gattungsgemäßen Absatzhaltevorrichtungen derart auszu­bilden und zu gestalten, daß die geschilderten Nachteile vermieden werden. Darüberhinaus soll noch eine Verein­fachung der Konstruktion erreicht werden, so daß wenige Einzelteile erforderlich sind und eine wirtschaftlichere Herstellung möglich ist.The purpose of the present invention is therefore to design and design the generic heel holding devices in such a way that the disadvantages described are avoided. In addition, a simplification of the construction is to be achieved so that few individual parts are required and more economical production is possible.

Dies ist erfindungsgemäß dadurch erreicht, daß der in Öffnungsrichtung des Sohlenhalters vorn liegende Roll­körper in einer Kulisse im als Druckhebel ausgebildeten Öffnungshebel gelagert ist und daß die Kulisse einen bezogen auf die Achse des Öffnungshebels wenigstens an­nähernd radialen Führungsabschnitt aufweist. Durch diese Konstruktion wird beim Betätigen des Öffnungs­hebels der Sohlenhalter sofort entlastet, so daß er im Bedarfsfall auch sofort kraftlos hochgeschwenkt werden kann.This is achieved in that the in The opening direction of the sole holder at the front is supported in a link in the opening lever designed as a pressure lever and that the link has a guide section which is at least approximately radial with respect to the axis of the opening lever. Through this construction, the sole holder is immediately relieved when the opening lever is actuated, so that it can also be swung up without power immediately if necessary.

Zweckmäßig sind der Sohlenhalter und der Öffnungshebel koaxial zueinander gelagert. Hierdurch ergibt sich eine äußerst einfache Ausführung der Absatzhaltevorrichtung. Die Hauptmerkmale der Erfindung lassen sich jedoch auch bei Ausführungen realisieren, bei denen der Öffnungshebel auf einer eigenen Achse entweder im Tragteil oder im Sohlenhalter gelagert ist.The sole holder and the opening lever are expediently mounted coaxially to one another. This results in an extremely simple design of the heel holding device. However, the main features of the invention can also be realized in versions in which the opening lever is mounted on its own axis either in the support part or in the sole holder.

Für den Fall, daß der Rollkörper unmittelbar und nicht eine besondere Tragachse für den Rollkörper in der Ku­lisse gelagert ist, muß der Führungsabschnitt der Kulisse eine Länge aufweisen, die dem doppelten Durchmesser des Rollkörpers entspricht.In the event that the rolling body is mounted directly and not a special supporting axis for the rolling body in the link, the guide section of the link must have a length that corresponds to twice the diameter of the rolling body.

Vorzugsweise besitzt die Kulisse bezogen auf die Achse des Öffnungshebels einen tangentialen Freiraum. Hier­durch ist der Öffnungshebel nicht gezwungen, beim Ski­laufen die Bewegungen des Sohlenhalters im sogenannten Elastizitätsbereich mitzumachen.The link preferably has a tangential free space with respect to the axis of the opening lever. As a result, the opening lever is not forced to follow the movements of the sole holder in the so-called elastic range when skiing.

Als Vorteilhaft hat es sich erwiesen, daß als an den Rollkörpern angreifende Feder eine Schraubenzugfeder vor­gesehen ist. Nicht ganz so kostengünstig kann jedoch auch eine Gasfeder Verwendung finden. In Verbindung mit einem Federkäfig läßt sich aber auch in an sich bekann­ter Weise eine Druckfeder verwenden. Weiter können mindestens zwei Federn vorgesehen und parallel geschaltet sein.It has proven to be advantageous that a helical tension spring is provided as the spring acting on the rolling elements. However, a gas spring can also be used not so cheaply. Combined with a spring cage can also use a compression spring in a manner known per se. Furthermore, at least two springs can be provided and connected in parallel.

Um ohne besonderen Aufwand zu erreichen, daß der Sohlen­halter schon mit Beginn der Betätigung des Öffnungshebels automatisch aufschwenken kann, greift eine den Öffnungs­hebel belastende Haltefeder mit ihrem zweiten Ende im Sinne des Öffnens am Sohlenhalter an. Hierbei hat es sich als zweckmäßig erwiesen, daß als Haltefeder eine auf der Achse des Sohlenhalters gelagerte Schenkelfeder dient.In order to ensure that the sole holder can automatically swing open as soon as the opening lever is actuated, a holding spring loading the opening lever engages the sole holder with its second end in the sense of opening. It has proven to be advantageous that a leg spring mounted on the axis of the sole holder serves as the retaining spring.

An exemplary embodiment of the subject matter of the invention is described in detail below with reference to the accompanying drawings. Show it:
  • 1 is a heel holding device in longitudinal section along the line II in Fig. 2,
  • 2 shows a cross section through the heel holding device along the line II-II in FIG. 1,
  • 3 shows a representation corresponding to FIG. 1, but in the current state of an involuntary triggering,

Die dargestellte Absatzhaltevorrichtung einer Sicherheits-­Skibindung besitzt einen Tragteil 1, der in beliebiger be­kannter weise auf einem Ski zu befestigen ist. Beispiels­weise kann die Befestigung unmittelbar erfolgen oder mittelbar über eine Drehscheibe oder eine eine Längsverschie­bung ermöglichende schienenartige Grundplatte. Von der Basis des Tragteils erstrecken sich zwei Wangen 2, 3 senk­recht nach oben, wie insbesondere aus Fig. 2 zu ersehen ist. Diese Wangen trage.n eine Achse 4, die in Bezug auf die Gebrauchslage der Vorrichtung horizontal und quer zur Skilängsrichtung liegt.The heel-holding device shown of a safety ski binding has a support part 1 which can be fastened on a ski in any known manner. For example, the attachment can take place directly or indirectly via a turntable or a rail-like base plate which enables longitudinal displacement. Two cheeks 2, 3 extend vertically upward from the base of the supporting part, as can be seen in particular from FIG. 2. These cheeks carry an axis 4 which is horizontal and transverse to the longitudinal direction of the ski in relation to the position of use of the device.

Auf der Achse 4 ist ein Sohlenhalter 5 schwenkbar gelagert, der in üblicher Weise mit einem Schließpedal 6 versehen ist. Der Sohlenhalter steht unter dem Einfluß einer Schraubenzug­feder 7, die mit ihren beiden Enden an jeweils einem Roll­körper 8 bzw. 9 aufgehängt ist (siehe Fig. 2). Die Wangen 2, 3 sing kongruent ausgebildet. Jede Wange besitzt für jeden Rollkörper 8, 9 eine Laufbahn, die sich aus zwei Abschnitten 10, 11 bzw. 12, 13 zusammensetzt. Ebenso weist auch der Sohlen­halter 5 für jeden Rollkörper 8, 9 eine Laufbahn auf, die sich aus den Abschnitten 14, 15 bzw. 16, 17 zusammensetzt. Wie Fig. 1 erkennen läßt, verlaufen die beiden Abschnitte jeder Laufbahn winkelig zueinander, wobei die zum jeweils anderen Rollkörper 9, 8 gerichteten Abschnitte 12, 16 bzw. 11, 15 um die Achse 4 des Sohlenhalters 5 gekrümmt sind. In dieser Position des Sohlenhalters, also in dem Gebrauchszustand der Vorrichtung, bilden die Abschnitte 11 und 14 eine Rastmulde für den Rollkörper 8 und die Abschnitte 13, 16 eine Rast­mulde für den Rollkörper 9.On the axis 4, a sole holder 5 is pivotally mounted, which is provided in the usual way with a closing pedal 6. The sole holder is under the influence of a helical tension spring 7, which is suspended with its two ends on a roller body 8 or 9 (see FIG. 2). The cheeks 2, 3 are congruent. Each cheek has a track for each rolling element 8, 9, which is composed of two sections 10, 11 and 12, 13, respectively. Likewise, the sole holder 5 also has a track for each rolling element 8, 9, which is composed of the sections 14, 15 and 16, 17, respectively. As can be seen in FIG. 1, the two sections of each track run at an angle to one another, the sections 12, 16 and 11, 15 directed towards the other rolling elements 9, 8 being curved about the axis 4 of the sole holder 5. In this position of the sole holder, that is to say when the device is in use, the sections 11 and 14 form a locking trough for the rolling body 8 and the sections 13, 16 form a locking trough for the rolling body 9.

Die Absatzhaltevorrichtung besitzt noch einen als Druck­hebel ausgebildeten Öffnungshebel 18 in Form eines im wesent­lichen U-förmigen Blechstanzstücks. Der Steg 19 ist in üblicher Weise mit einer Mulde 20 versehen, die zum Ein­setzen einer Skistockspitze dient. Mittels seinen Schen­ keln 21, 22 ist der Öffnungshebel ebenfalls auf der Achse 4 am Tragteil 1 gelagert. Jeder Schenkel weist eine Kulisse 23 auf, in die sich der Rollkörper 8 mit jeweils einem Ende er­streckt. Die Kulisse besitzt einen Führungsabschnitt 24, dessen Länge im vorliegenden Fall dem doppelten Durchmesser des Rollkörpers entspricht und der sich annähernd radial zur Achse 4 erstreckt. Von diesem Führungsabschnitt ausge­hend besitzt die Kulisse einen im wesentlichen tangential zur Achse 4 verlaufenden Freiraum 25, der dem Rollkörper 8 eine ausreichende Bewegungsmöglichkeit ohne Mitnahme des Öffnungshebels 18 gibt.The heel holding device also has an opening lever 18 designed as a pressure lever in the form of an essentially U-shaped sheet metal stamping. The web 19 is provided in the usual way with a depression 20, which is used to insert a ski pole tip. By means of his pens keln 21, 22, the opening lever is also mounted on the axis 4 on the support member 1. Each leg has a link 23 into which the rolling body 8 extends with one end each. The link has a guide section 24, the length of which in the present case corresponds to twice the diameter of the rolling body and which extends approximately radially to the axis 4. Starting from this guide section, the link has a free space 25 which extends essentially tangentially to the axis 4 and which gives the rolling element 8 a sufficient possibility of movement without taking the opening lever 18 with it.

Greift, ausgehend von der in Fig. 1 dargestellten Gebrauchs­lage der Absatzhaltevorrichtung, am Sohlenhalter 5 eine nach oben gerichtete die Vorspannung der Schraubenzugfeder 7 übersteigende Kraft an, bewegt sich der Sohlenhalter 5 in Bezug auf die Darstellung um die Achse 4 entgegen dem Uhrzeigersinn und nimmt über den Abschnitt 14 seiner oberen Laufbahn den von der Schraubenzugfeder belasteten Rollkörper 8 mit, der zwangsläufig am Abschnitt 11 der Wangen 2, 3 entlang gleitet. Unter dem Einfluß der Schrauben­zugfeder 7 stellt sich der Sohlenhalter 5 beim Nachlassen der Kraft wieder in seine Ausgangslage zurück. Ist eine am Sohlen­halter nach oben hin angreifende Kraft entsprechend groß, zum Beispiel bei einem Frontalsturz des Skiläufers, so lau­fen bei Erreichen des Auslösepunktes die Rollkörper 8, 9 auf den jeweils anderen Abschnitt 10 bzw. 17 der entsprechenden Laufbahnen. Mit diesem Übertritt ergibt sich eine Belastung des Sohlenhalters durch die Schraubenzugfeder im Sinne des Öffnens. Fig. 3 zeigt den Momentanszustand der Vorrichtungs­teile im Augenblick des Erreichens des Auslösepunktes, während Fig. 4 den Momentanzustand der Vorrichtungsteile im geöffneten Zustand zeigt.If, starting from the position of use of the heel holding device shown in FIG. 1, an upward force exceeding the pretension of the coil tension spring 7 acts on the sole holder 5, the sole holder 5 moves counterclockwise with respect to the illustration about the axis 4 and takes over the section 14 of its upper track with the rolling element 8 loaded by the helical tension spring, which inevitably slides along the section 11 of the cheeks 2, 3. Under the influence of the tension spring 7, the sole holder 5 returns to its initial position when the force decreases. If a force acting upwards on the sole holder is correspondingly large, for example in the event of a frontal fall of the skier, when the trigger point is reached, the rolling elements 8, 9 run on the respective other sections 10 and 17 of the corresponding tracks. With this step, the sole holder is loaded by the helical tension spring in the sense of opening. FIG. 3 shows the momentary state of the device parts at the moment the trigger point is reached, while FIG. 4 shows the momentary state of the device parts in the open state.

Im geöffneten Zustand entsprechend Fig. 4 ist die Absatz­haltevorrichtung einstieg-bereit. Beim Einsteigen schwenkt der Sohlenhalter in Bezug auf die Darstellung durch Belasten des Schließpedals 6 um die Achse 4 im Uhrzeigersinn. Dieses erfolgt zunächst gegen die Kraft der Schraubenzugfeder 7. Der zuvor erwähnte Auslösepunkt ist umgekehrt nunmehr der Schließpunkt, nach dessen Erreichen der Sohlenhalter unter dem Einfluß der Schraubenzugfeder in seine Schließlage ge­schwenkt wird.4, the heel holding device is ready for entry. When getting in, the sole holder pivots in a clockwise direction with respect to the illustration by loading the closing pedal 6. This takes place initially against the force of the helical tension spring 7. The aforementioned trigger point is conversely now the closing point, after reaching which the sole holder is pivoted into its closed position under the influence of the helical tension spring.

Zum willkürlichen Öffnen der Absatzhaltevorrichtung ist ausgehend von der Darstellung nach Fig. 1 der Öffnungs­hebel 18 entgegen dem Uhrzeigersinn zu schwenken. Hierbei erfolgt eine Mitnahme des Rollkörpers 8 durch den Führungs­abschnitt 24 der Kulisse 23 im Öffnungshebel. Durch die Entlastung des Sohlenhalters 5 kann dieser praktisch kraft­los in Öffnungsrichtung geschwenkt werden. Mit dem Über­gang des Rollkörpers 8 vom Abschnitt 11 der oberen Laufbahn auf deren Abschnitt 10 erfolgt nach entsprechendem Schwenken des Sohlenhalters der Übergang des Rollkörpers 9 auf den je­weils anderen Abschnitt der unteren Laufbahnen, so daß sich dann der Sohlenhalter automatisch bis in seine Offenstellung bewegt, die in Fig. 6 dargestellt ist.For the arbitrary opening of the heel holding device, starting from the illustration according to FIG. 1, the opening lever 18 is to be pivoted counterclockwise. In this case, the rolling element 8 is carried along by the guide section 24 of the link 23 in the opening lever. By relieving the pressure on the sole holder 5, the sole holder 5 can be pivoted practically without force in the opening direction. With the transition of the rolling body 8 from section 11 of the upper track to its section 10, after appropriate swiveling of the sole holder, the transition of the rolling body 9 to the other section of the lower tracks takes place, so that the sole holder then automatically moves into its open position, which is shown in Fig. 6.

Ein Vergleich der Fig. 4 und 6 läßt erkennen, daß der Öffnungshebel 18 gegenüber dem Sohlenhalter 5 bewegbar ist. Diese Bewegungsmöglichkeit ergibt sich aus dem Freiraum 25 der Kulisse 23 und bietet den Vorteil, daß der Öffnungshebel nicht zwangsläufig alle Bewegungen des Sohlenhalters während des Skilaufens mitmachen muß. Damit die Absatzhaltevorrich­tung auch im geöffneten Zustand keinen freibeweglichen Teil besitzt, ist der Öffnungshebel 18 von einer üblichen und nicht dargestellten Haltefeder belastet, die ihn nach einer Betätigung aus der Lage nach der Fig. 6 in die nach Fig. 4 zurückschwenkt. Diese Feder kann beispielsweise als Schenkel­ feder ausgebildet und auf der Achse 4 gelagert mit ihrem zweiten Ende am Sohlenhalter 5 angreifen und diesen im Sinne des Öffnens belasten. Auf diese Weise kann dann der Sohlenhalter schon mit Beginn der Betätigung des Öffnungs­hebels automatisch aufschwenken.A comparison of FIGS. 4 and 6 reveals that the opening lever 18 can be moved relative to the sole holder 5. This possibility of movement results from the free space 25 of the link 23 and has the advantage that the opening lever does not necessarily have to participate in all movements of the sole holder during skiing. So that the heel holding device does not have a freely movable part even in the open state, the opening lever 18 is loaded by a conventional and not shown holding spring, which pivots it back after actuation from the position according to FIG. 6 into that according to FIG. 4. This spring can, for example, as a leg formed spring and mounted on the axis 4 with its second end to attack the sole holder 5 and load it in the sense of opening. In this way, the sole holder can automatically swing open when the opening lever is actuated.

Wie Fig. 2 zeigt, ist in Bezug auf die vertikale Längsebene eine spiegelgleiche Anordnung der einzelnen Teile getroffen. Um der Schraubenzugfeder 7einen ausreichenden Platz zu ge­ben, besitzt der Sohlenhalter 5 innenseitig einen entspre­chenden Freiraum 26 (siehe Fig. 2) und beiderseits davon jeweils einen Schlitz 27 (siehe Fig. 1) als Freiraum für die Schenkel 21, 22 des Öffnungshebels.As shown in FIG. 2, a mirror-like arrangement of the individual parts is made with respect to the vertical longitudinal plane. In order to give the coil tension spring 7 sufficient space, the sole holder 5 has a corresponding free space 26 on the inside (see FIG. 2) and a slot 27 on both sides thereof (see FIG. 1) as free space for the legs 21, 22 of the opening lever.

Anstelle der beschriebenen Ausführung mit den beiden Wangen 2, 3 und der sich zwischen diesen erstreckenden Schraubenzugfeder 7 ist auch eine Konstruktion möglich, bei der umgekehrt der Tragteil einen zapfenartigen Lager­teil aufweist, der zentral angeordnet ist, und bei der dann beiderseits dieses Lagerteils jeweils eine Feder an­geordnet ist. Beide Federn können auch außerhalb des Sohlenhalters angeordnet sein. In diesem Fall sind ledig­lich die Rollkörper entsprechend lang auszubilden und in den Seitenwänden des Sohlenhalters die zur Relativbewe­gung notwendigen Langlöcher vorzusehen. Weiter ist es selbstverständlich nicht notwendig, die Rollkörper ein­stückig auszubilden, wie es der Einfachheit halber im vorliegenden Fall geschehen ist. Vielmehr ist es dem Fachmann bekannt, Rollkörper als Ringe auszubilden und auf einer Achse zu lagern, an der die Feder angreift. Schließlich ist es auch noch ohne weiters möglich, eine übliche Verstellvorrichtung vorzusehen, mit der sich die Federvorspannung entsprechend den gewünschten Auslöse­kräften einstellen läßt.Instead of the described embodiment with the two cheeks 2, 3 and the tension spring 7 extending between them, a construction is also possible in which, conversely, the supporting part has a pin-like bearing part which is arranged centrally, and in which case a spring is located on both sides of this bearing part is arranged. Both springs can also be arranged outside the sole holder. In this case, only the rolling elements are to be made long enough and the elongated holes necessary for the relative movement are to be provided in the side walls of the sole holder. Furthermore, it is of course not necessary to form the rolling body in one piece, as was done in the present case for the sake of simplicity. Rather, it is known to the person skilled in the art to design rolling bodies as rings and to mount them on an axis on which the spring acts. Finally, it is also easily possible to provide a conventional adjusting device with which the spring preload can be adjusted in accordance with the desired triggering forces.
