Description

Die Erfindung betrifft eine vordere Sohlenhaltevorrichtung an einer Skibindung, wie sie im Oberbegriff des Patentanspruchs 1 im einzelnen angegeben ist.The invention relates to a front sole holding device on a ski binding, as specified in the preamble of claim 1 in detail.

Eine Sohlenhaltevorrichtung dieser Art ist aus der DE 40 07 667 C1 bekannt. Bei dieser bekannten Sohlenhaltevorrichtung bildet die Lagerachse gleichzeitig das Auflager für das vordere Ende des Skistiefels und die Schwenkachse für einen zur Spanneinrichtung gehörenden Spannbügel. Daher ist es erforderlich, die Lagerachse ihrerseits auf dem Ski um sich selbst drehbar zu lagern. Dies verlangt jedoch eine relativ schwere und kostspielige Konstruktion, die überdies verschiedene Sonderteile notwendig macht.A sole holding device of this type is known from DE 40 07 667 C1. In this known sole holding device, the bearing axis simultaneously forms the support for the front end of the ski boot and the pivot axis for a tensioning bracket belonging to the tensioning device. It is therefore necessary to turn the bearing axis on the ski to rotate itself. However, this requires a relatively heavy and expensive construction, which also makes various special parts necessary.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Sohlenhaltevorrichtung der eingangs erwähnten Art so auszubilden, daß auf eine drehbare Lagerung der Lagerachse verzichtet und damit eine konstruktive Vereinfachung und gleichzeitig eine Verbilligung des Gesamtaufbaus ohne die Notwendigkeit der Verwendung von Sonderteilen mit hohem Fertigungsaufwand erzielt werden kann.The invention is therefore based on the object of designing a sole holding device of the type mentioned at the outset in such a way that a rotatable mounting of the bearing axis is dispensed with and thus a constructional simplification and at the same time a reduction in the cost of the overall structure can be achieved without the need to use special parts with high production costs.

Die gestellte Aufgabe wird gemäß der Erfindung gelöst durch eine Ausbildung der Sohlenhaltevorrichtung, wie sie im Patentanspruch 1 angegeben ist; vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The stated object is achieved according to the invention by designing the sole holding device as specified in claim 1; advantageous refinements and developments of the invention result from the subclaims.

Dank der Drehbarkeit der Traghülse auf der und um die Lagerachse kann bei der Sohlenhaltevorrichtung gemäß der Erfindung die Lagerachse selbst auf dem Ski feststehend montiert werden, was eine erhebliche konstruktive Vereinfachung und Verbilligung mit sich bringt. Außerdem läßt sich die Lagerachse ohne weiteres in einem Teilbereich ihrer Länge freilegen, wodurch eine Befestigung von Zusatzteilen wie beispielsweise eines Harscheisens an der Lagerachse selbst möglich wird.Thanks to the rotatability of the support sleeve on and around the bearing axis, the bearing axis itself can be fixedly mounted on the ski in the sole holding device according to the invention, which entails considerable design simplification and cost reduction. In addition, the bearing axis can easily be exposed in a partial area of its length, which enables attachment of additional parts such as a crampon to the bearing axis itself.

Die in der Zeichnung dargestellte vordere Sohlenhaltevorrichtung ist auf einem nur in einem Ausschnitt gezeigten Ski Sk montiert, und sie dient zum Festhalten eines ebenfalls nur teilweise gezeigten Skistiefels St, der eine Sohle So mit einem im vorderen Zehenbereich überstehenden Rand Ra besitzt.The front sole holding device shown in the drawing is mounted on a ski Sk shown only in a cutout, and it serves to hold a ski boot St, which is also only partially shown, and which has a sole So with an edge Ra protruding in the front toe region.

Die tragende Unterlage für den Skistiefel St bildet bei der dargestellten Sohlenhaltevorrichtung beim Tourenlauf eine Lagerachse 1, die auf dem Ski Sk quer zu dessen Längsachse und parallel zu seiner Oberfläche mit Abstand dazu mittels eines Lagerbocks 9 fest montiert ist. Auf die Lagerachse 1 ist eine Traghülse 2 aufgeschoben, die sich auf der Lagerachse 1 frei dagegen verdrehen läßt und ihrerseits die unmittelbare Auflagefläche für den Skistiefel St zu dessen Abstützung beim Tourenlauf darstellt, wie dies in Fig. 4 gezeigt ist.The supporting base for the ski boot St forms a bearing axis 1 in the sole holding device shown when touring, which is fixedly mounted on the ski Sk transversely to its longitudinal axis and parallel to its surface at a distance from it by means of a bearing block 9. On the bearing axis 1, a support sleeve 2 is pushed, which can be freely rotated on the bearing axis 1 and in turn represents the immediate contact surface for the ski boot St to support it during touring, as shown in FIG. 4.

Die Spannkraft zum Festspannen des Skistiefels St auf der Traghülse 2 liefert eine Spanneinrichtung, die bei dem dargestellten Beispiel einen auf der Lagerachse 1 dagegen verdrehbar zu beiden Seiten der Traghülse 2 gelagerten Spannbügel 5 von angenäherter U-Form und einen auf dem Quersteg dieses Spannbügels 5 umklappbar gelagerten zweiarmigen Strammerhebel 6 aufweist. In der in Fig. 4 gezeigten Tourenstellung drückt das eine Ende dieses Strammerhebels 6 von oben her auf den überstehenden vorderen Rand Ra der Sohle So des Skistiefels St und diesen damit gegen die Traghülse 2.The tensioning force for tightening the ski boot St on the support sleeve 2 is provided by a tensioning device which, in the example shown, has a tension bracket 5 of approximately U-shape which is rotatably mounted on the bearing axis 1 on both sides of the support sleeve 2 and one on the crosspiece of this tension bracket 5 can be folded down has two-armed tensioner lever 6. In the touring position shown in FIG. 4, one end presses this tensioning lever 6 from above onto the protruding front edge Ra of the sole So of the ski boot St and thus against the support sleeve 2.

Anstelle des U-förmigen Spannbügels 5 kann mit gleicher Wirkung auch ein entsprechend gelagertes Spannseil als Träger für den Strammerhebel 6 vorgesehen werden, wobei es in beiden Fällen von Vorteil ist, das jeweilige Spannelement längenverstellbar zu machen, um eine Anpassungsmöglichkeit an unterschiedliche Stiefelabmessungen und insbesondere Sohlendicken zu schaffen.Instead of the U-shaped tensioning bracket 5, a correspondingly mounted tensioning rope can also be provided as a support for the tensioning lever 6, with it being advantageous in both cases to make the respective tensioning element adjustable in length in order to be able to adapt to different boot dimensions and in particular sole thicknesses to accomplish.

Auf dem für das Aufsetzen des Skistiefels St bestimmten Teil ihrer Oberfläche ist die Traghülse 2 mit einer Riffelung 3 versehen oder sonst im Sinne einer Verstärkung der zwischen ihr und der Sohle So des Skistiefels St wirksamen Reibung gestaltet.On the part of its surface intended for putting on the ski boot St, the support sleeve 2 is provided with a corrugation 3 or is otherwise designed to reinforce the friction effective between it and the sole So of the ski boot St.

Die von dem Strammerhebel 6 auf den Skistiefel St ausgeübte Spannkraft ist im allgemeinen so groß, daß die Sohle So des Skistiefels St so fest zwischen dem von oben auf ihren überstehenden Rand Ra drückenden unteren Ende des Strammerhebels 6 einerseits und der von unten an ihrer Unterseite anliegenden Traghülse 2 andererseits eingespannt wird, daß ein sicheres Festhalten des Skistiefels St an der Traghülse 2 auch dann gewährleistet ist, wenn zwischen der Sohle So des Skistiefels St und der Traghülse 2 nur ein reiner Reibschluß vorgesehen ist, doch ist es auch möglich, dazwischen einen Formschluß vorzusehen, wie er mittels einer in Fig. 3 sichtbaren Ausnehmung in der Unterseite der Sohle So des Skistiefels St erreichbar ist.The tensioning force exerted by the tensioning lever 6 on the ski boot St is generally so great that the sole So of the ski boot St so firmly between the lower end of the tensioning lever 6, which presses on its projecting edge Ra from above, and the one from the bottom resting against its underside Support sleeve 2 is clamped on the other hand, that a secure hold of the ski boot St on the support sleeve 2 is guaranteed even if only a pure frictional engagement is provided between the sole So of the ski boot St and the support sleeve 2, but it is also possible to have a positive connection between them to provide how it can be reached by means of a recess visible in FIG. 3 in the underside of the sole So of the ski boot St.

Die in der Zeichnung gezeigte Ausführung der Spanneinrichtung mit dem um die horizontale Lagerachse 1 schwenkbaren Spannbügel 5 und dem darauf gelagerten Strammerhebel 6 stellt nur eine wenn auch bevorzugte Möglichkeit dar. An ihrer Stelle kann auch eine Spanneinrichtung vorgesehen werden, die das vordere Ende des Skistiefels St mit dein überstehenden Rand Ra von vorn her umgreift und bei ihrem Schließen nach Art eines Klapphebelverschlusses einen Druck auf den Skistiefel St auch in Richtung auf die Traghülse 2 ausübt und diese damit in fester Anlage an der Sohle So des Skistiefels St hält.The embodiment of the tensioning device shown in the drawing, with the tensioning bracket 5 pivotable about the horizontal bearing axis 1 and the tensioning lever 6 mounted thereon, represents only one, albeit preferred, possibility. In its place, a tensioning device can also be provided, which extends the front end of the ski boot St grips with your protruding edge Ra from the front and when it closes in the manner of a folding lever closure also exerts pressure on the ski boot St in the direction of the support sleeve 2 and thus holds it firmly against the sole So of the ski boot St.

In Verlängerung der Traghülse 2 in Fig. 3 nach vorn kann an deren Oberseite ein in der Zeichnung nicht eigens gezeigter abgewinkelter Anschlag vorgesehen sein, der ein lagerichtiges Aufsetzen des Skistiefels St auf die Traghülse 2 für den Tourenlauf erleichtert.In an extension of the support sleeve 2 in FIG. 3 to the front, an angled stop (not specifically shown in the drawing) can be provided on the upper side thereof, which facilitates the correct placement of the ski boot St on the support sleeve 2 for touring.

Ebenso für den Tourenlauf ist es von Vorteil, eine Möglichkeit zum Befestigen von Zusatzteilen an der Sohlenhalterung zu haben. Dazu ist bei dem dargestellten Beispiel die Traghülse 2 in einem mittleren Bereich 4 ihrer Länge mit quadratischem Außenquerschnitt ausgeführt, wie am besten die Darstellung in Fig. 3 läßt. Dadurch wird beispielsweise ein Einhängen eines Harscheisens entlang der Lagerachse 1 möglich.Also for touring it is advantageous to have an option to attach additional parts to the sole holder. For this purpose, in the example shown, the support sleeve 2 is designed in a central region 4 of its length with a square outer cross section, as best shown in FIG. 3. This makes it possible, for example, to attach a crampon along the bearing axis 1.

Die erfindungsgemäß ausgebildete Sohlenhaltevorrichtung läßt sich entsprechen der Darstellung in Fig. 4 für den Tourenlauf verwenden, bei dem der Skistiefel St gemeinsam mit der Traghülse 2 um die Lagerachse 2 nach oben geschwenkt werden kann, sie kann jedoch in Verbindung mit einer in der Zeichnung nicht gezeigten hinteren Stiefelhalterung auch eine für den Abfahrtslauf geeignete feste Verbindung des Skistiefels St mit dem Ski Sk gewährleisten. Dazu ist bei dem gezeigten Beispiel mit der Traghülse 2 ein Sohlenhalter 7 verbunden, der sich gemeinsam mit der Traghülse 2 um die Lagerachse 1 schwenken läßt. Wie insbesondere die Darstellungen in Fig. 3 und 4 zeigen, weist dieser Sohlenhalter 7 in der Seitenansicht die Form eines L auf, und er reicht in der in Fig. 1, bis 3 gezeigten Schwenkstellung der Traghülse 2 nach hinten über diese hinaus und kann so den nach vorn überstehenden Rand Ra der Sohle So des Skistiefels St übergreifen, wenn dieser für den Abfahrtslauf unmittelbar auf die Oberfläche des Skis Sk aufgesetzt wird, wie dies die Darstellung in Fig. 3 zeigt. In dieser Schwenkstellung, die durch zwei am Lagerbock 9 auf beiden Seiten angebrachte Anschläge 8 festgelegt ist, hält der Sohlenhalter 7 das vordere Ende des Skistiefels St auf dem Ski Sk fest, wie dies auch in Fig. 2 angedeutet ist.The sole holding device designed according to the invention can correspond to the representation in FIG. 4 used for touring, in which the ski boot St can be pivoted upwards together with the support sleeve 2 about the bearing axis 2, but it can be used in conjunction with one not shown in the drawing rear boot holder also ensure a firm connection of the ski boot St suitable for downhill skiing with the ski sk. For this purpose, a sole holder 7 is connected to the support sleeve 2 in the example shown, which can be pivoted together with the support sleeve 2 about the bearing axis 1. 3 and 4 in particular, this sole holder 7 has the shape of an L in the side view, and in the pivot position of the support sleeve 2 shown in FIGS overlap the protruding edge Ra of the sole So of the ski boot St when it is placed directly on the surface of the ski Sk for downhill skiing, as the illustration in FIG. 3 shows. In this swivel position, which is fixed by two stops 8 attached to the pedestal 9 on both sides, the sole holder 7 holds the front end of the ski boot St on the ski Sk, as is also indicated in FIG. 2.

Eine analoge Wirkung läßt sich auch mit einer von der Traghülse 2 getrennten Ausführung des Sohlenhalters 7 in Form eines an dem Lagerbock 9 angebrachten und aus einer inaktiven Stellung für den Tourenlauf in eine aktive Stellung für den Abfahrtslauf überführbaren Formteils passender Gestalt und passender Länge erzielen. Bevorzugt ist dabei die Gestaltung des Sohlenhalters mit einem Profil in Form eines L, wobei die Anlenkung des Sohlenhalters an seinem Träger mit dem freien Ende des langen Schenkels des L erfolgen kann und die beiden L-Schenkel zweckmäßig umklappbar miteinander verbunden sind.An analogous effect can also be more suitable with a design of the sole holder 7 which is separate from the support sleeve 2 in the form of a molded part which is attached to the bearing block 9 and can be transferred from an inactive position for touring to an active position for downhill skiing Achieve shape and appropriate length. Preferred is the design of the sole holder with a profile in the form of an L, wherein the articulation of the sole holder on its support can be carried out with the free end of the long leg of the L and the two L legs are expediently connected to one another in a foldable manner.

Bei allen Ausführungen für den Sohlenhalter kann durch dessen höhenverstellbare Anordnung und Ausbildung die Möglichkeit einer Anpassung an Skistiefel mit unterschiedlicher Sohlendicke geschaffen werden.In all versions for the sole holder, its height-adjustable arrangement and design make it possible to adapt it to ski boots with different sole thicknesses.

Im Prinzip läßt sich die Erfindung beschreiben als eine vordere Sohlenhaltevorrichtung an einer Skibindung für einen Skistiefel, der eine im vorderen Zehenbereich überstehende Sohle aufweist.In principle, the invention can be described as a front sole holding device on a ski binding for a ski boot that has a sole that protrudes in the front toe region.

Dabei weist diese Sohlenhaltevorrichtung eine Lagerachse für ein Abstützen des vorderen Bereichs des Skistiefels von unten her auf, die auf dem Ski mit Abstand von dessen Oberfläche und parallel dazu gehalten ist und quer zur Skilängsachse verläuft. Außerdem ist eine verstellbare Spanneinrichtung zum Ausüben eines auf die Lagerachse zu gerichteten Spanndrucks auf den Skistiefel zu dessen Festhalten an der Lagerachse vorgesehen.This sole holding device has a bearing axis for supporting the front region of the ski boot from below, which is held on the ski at a distance from its surface and parallel to it and runs transversely to the longitudinal axis of the ski. In addition, an adjustable tensioning device is provided for exerting a tensioning pressure on the ski boot towards the bearing axle in order to hold it on the bearing axle.

Zur Vereinfachung der Konstruktion ist gemäß der Erfindung auf der auf dem Ski festgehaltenen Lagerachse eine Traghülse um die Lagerachse drehbar gelagert, auf die der Skistiefel ohne Berührung mit der Lagerachse aufsetzbar ist. Diese Traghülse ist bevorzugt auf einem während des Tourenlaufs wirksamen Teil ihrer Oberfläche mit einer Riffelung versehen und mit einem verstellbaren und während des Abfahrtslaufs den überstehenden Rand der Stiefelsohle übergreifenden Sohlenhalter verbunden. Die Spanneinrichtung weist bevorzugt einen auf der Lagerachse zu beiden Seiten der Traghülse um die Lagerachse schwenkbar gelagerten und einen umklappbaren Strammerhebel tragenden Spannbügel auf.To simplify the construction, according to the invention, a support sleeve is rotatably mounted about the bearing axis on the bearing axis held on the ski, onto which the ski boot can be placed without contacting the bearing axis. This support sleeve is preferably provided with a corrugation on a part of its surface which is effective during the touring run and is connected to an adjustable sole holder which overlaps the protruding edge of the sole of the boot during the downhill run. The tensioning device preferably has a tensioning bracket which is pivotally mounted on the bearing axis on both sides of the support sleeve about the bearing axis and which carries a foldable tensioning lever.
