Die Erfindung gemäß dem Anspruch 1 betrifft einen Fersenhalter für eine Skibindung mit einer Basisplatte mit der der Fersenhalter mit der Oberfläche eines Skis oder Snowboards verbunden werden kann, einer Verbindungsstruktur die mit der Basisplatte verbunden werden kann und einer Spannvorrichtung mit der ein Skischuh auf den Ski gespannt wird.The invention according to
Bei der Basisplatte handelt es sich um eine Basisstruktur, die fest mit dem Ski verbunden werden kann oder verbunden, zum Beispiel in die Skioberfläche integriert, ist. Die Basisstruktur kann aus einem Stück bestehen und dazu dienen, einen Zehenhalter und den Fersenhalter mit dem Ski zu verbinden. Die Basisstruktur kann alternativ wenigstens zwei Teile aufweisen, von denen eines den Zehenhalter und ein weiteres den Fersenhalter mit dem Ski verbindet.The base plate is a basic structure that can be fixedly connected to the ski or connected, for example integrated into the ski surface. The base structure can be made in one piece and used to connect a toe holder and the heel holder to the ski. The base structure may alternatively comprise at least two parts, one connecting the toe holder and another the heel holder to the ski.
Die Verbindungsstruktur umfasst ein erstes Verbindungstrukturteil und ein zweites Verbindungstrukturteil, wobei das erste Verbindungstrukturteil bei einer Querauslösung der Skibindung relativ zum zweiten Verbindungsstrukturteil in Richtung der Querauslösung bewegbar ist. Das erste Verbindungsstrukturteil kann relativ zum zweiten Verbindungsstrukturteil translatorisch bewegbar, querversetzbar, oder vorzugsweise rotatorisch verschwenkt werden, also dreh- oder schwenkbar sein. Dabei kann an oder in dem zweiten Verbindungsstrukturteil eine Führungsbahn oder Kulisse gebildet sein, die den Freiheitsgrad der relativen Bewegung zwischen den beiden Verbindungsstrukturteilen bestimmt. So kann die Führungsbahn beispielsweise so gebildet sein, dass das erste Verbindungsstrukturteil bei der relativen Bewegung zum ersten Verbindungsstrukturteil gleichzeitig von der Skioberfläche weg bewegt wird.The connection structure comprises a first connection structure part and a second connection structure part, wherein the first connection structure part is movable in a transverse release of the ski binding relative to the second connection structure part in the direction of transverse release. The first connection structure part can be translationally movable, transversely displaceable, or preferably rotationally pivoted relative to the second connection structure part, ie be rotatable or pivotable. In this case, a guideway or link can be formed on or in the second connection structure part, which determines the degree of freedom of the relative movement between the two connection structure parts. For example, the guide track may be formed in such a way that the first connection structure part is simultaneously moved away from the ski surface during the relative movement to the first connection structure part.
Die Spannvorrichtung umfasst einen Sohlenhalter in Form wenigstens eines Abrollkörpers, der im direkten Kontakt mit einer Skischuhsohle einen Skischuh auf den Ski oder das Snowboard spannt, wobei der wenigstens eine Abrollkörper eine Drehachse aufweist und mit der Spannvorrichtung so verbunden ist, dass er sich um seine Drehachse drehen kann.The tensioning device comprises a sole holder in the form of at least one rolling body, which in direct contact with a ski boot sole stretches a ski boot onto the ski or snowboard, the at least one rolling body having an axis of rotation and being connected to the tensioning device so as to be about its axis of rotation can turn.
Die Drehachse des Abrollkörpers kann senkrecht zur Skioberfläche stehen oder in einem Winkel der größer als 0° und kleiner als 90° ist. Bevorzugt steht die Drehachse in einem spitzen Winkel zur Skioberfläche, wobei der Winkel gegen ein hinteres Ende des Skischuhs geneigt ist, wodurch ein auf die Skischuhsohle wirkendes Kräftedreieck gebildet wird, mit einem großen Kraftvektor, der den Skischuh auf die Skioberfläche zu drückt, und einem kleineren Kraftvektor, der den Skischuh in die Skilaufrichtung drückt.The axis of rotation of the rolling body can be perpendicular to the ski surface or at an angle greater than 0 ° and less than 90 °. Preferably, the axis of rotation is at an acute angle to the ski surface, the angle being inclined towards a rear end of the ski boot, thereby forming a force triangle acting on the ski boot sole with a large force vector urging the ski boot toward the ski surface and a smaller one Power vector pushing the ski boot in the ski direction.
Um den Skischuh auf einem Snowboard oder einem Abfahrtski oder einem kombinierten Fahr- und Tourenski in der Fahrposition zu halten, spannt die Spannvorrichtung den Skischuh auf den Ski oder das Snowboard. Um das Risiko eines komplizierten Bruchs zu reduzieren, können Sicherheitsbindungen eine Querauslösung der Bindung beim Überschreiten einer bevorzugt vorgebbaren Querkraft vorsehen. Um die Querauslösung bei der bevorzugt einstellbaren Querauslösekraft zuverlässig zu gewährleisten, weist der Fersenhalter einen Sohlenhalter in Form eines Abrollkörpers auf, der mit der Spannvorrichtung so verbunden ist, dass der Sohlenhalter bzw. der Abrollkörper sich im mit der Spannvorrichtung verbundenen Zustand um seine zentrale Drehachse drehen kann und dadurch in Falle der Querauslösung des Fersenhalters an der Skischuhsole abrollt.To keep the ski boot in the riding position on a snowboard or a downhill ski or a combined touring and touring ski, the tensioning device tensions the ski boot onto the ski or snowboard. In order to reduce the risk of a complicated fracture, safety bonds can provide a transverse release of the bond when a preferably predetermined transverse force is exceeded. In order to reliably ensure the transverse release in the case of the preferably adjustable transverse release force, the heel holder has a sole holder in the form of a rolling body, which is connected to the tensioning device so that the sole holder or the rolling body is connected to the tensioning device Condition can rotate about its central axis of rotation and thereby rolls in case of transverse release of the heel holder on the ski boot brine.
Der Fersenhalter kann weiterhin eine Trittplatte aufweisen, die als Gleitplatte ausgebildet ist und in eine Richtung quer zu der Längsrichtung der Skibindung beweglich ist, sodass sie im Falle einer Querauslösung der Bindung sich in die Auslöserichtung bewegen kann.The heel holder may further comprise a tread plate which is formed as a slide plate and is movable in a direction transverse to the longitudinal direction of the ski binding so that it can move in the triggering direction in the event of transverse release of the binding.
Der Sohlenhalter wird durch wenigstens einen Abrollkörper gebildet, bevorzugt wird der Sohlenhalter von zwei oder mehr Abrollkörpern gebildet, von denen jeder einzeln um seine Rotationsachse drehbar mit dem Spannvorrichtungskörper verbunden ist.The sole holder is formed by at least one rolling body, preferably the sole holder is formed by two or more rolling bodies, each of which is individually connected rotatably about its axis of rotation with the clamping device body.
Zur Aufnahme des oder der den Sohlenhalter bildenden Abrollkörper kann der Spannvorrichtungskörper gabelförmige Aufnahmearme aufweisen, wobei der oder die den Sohlenhalter bildenden Abrollkörper bevorzugt zwischen dem oberen und dem unteren Aufnahmearm des Spannvorrichtungskörpers angeordnet ist/sind.For accommodating the rolling body forming the sole holder, the tensioning device body may have fork-shaped receiving arms, wherein the rolling body or bodies forming the sole holder is / are preferably arranged between the upper and lower receiving arms of the tensioning device body.
Der Abrollkörper, der im Folgenden stellvertretend für den Sohlenhalter steht, kann eine rotationssymmetrische Form haben, z.B. die Form einer Rolle, Tonne, Scheibe, Kugel oder Teilkugel, oder einen Körper mit einer solchen geometrischen Form umfassen. Der Abrollkörper kann ein Kugel-, Tonnen- oder Nadellager mit einem drehbaren Außenring umfassen oder zumindest zum Teil durch Teile solch eines Lagers oder durch solch ein Lager selbst gebildet sein.The rolling body, which in the following is representative of the sole holder, may have a rotationally symmetrical shape, e.g. the shape of a roll, barrel, disc, sphere or part ball, or a body having such a geometric shape. The rolling body may comprise a ball, barrel or needle bearing with a rotatable outer ring or at least partially formed by parts of such a bearing or by such a camp itself.
Ist der Abrollkörper selbst als Drehlager gebildet, kann der Abrollkörper einen Lagerzentrumskörper aufweisen, der drehfest mit der Spannvorrichtung bzw. dem Aufnahmearm oder dem oberen Aufnahmearm und dem unteren Aufnahmearm verbunden ist und einen drehbaren Außenring oder Laufring aufweist, der den Lagerzentrumskörper an einer quer zur Drehrichtung des Abrollkörper weisenden Flanke umgibt. Die die Lagerkörper bildenden Kugeln, Tonnen oder Nadeln sind zwischen einer Flankenaußenseite des Lagerzentrumskörpers und einer Innenseite des Laufrings gefangen und bilden gemeinsam mit dem Laufring und dem Lagerzentrumskörper den Abrollkörper bzw. den Sohlenhalter.If the rolling body itself formed as a pivot bearing, the rolling body may have a bearing center body which is rotatably connected to the clamping device or the receiving arm or the upper receiving arm and the lower receiving arm and having a rotatable outer ring or race, the bearing center body at a direction transverse to the direction of rotation surrounds the rolling body facing flank. The bearing bodies forming balls, tons or needles are trapped between a flank outer side of the bearing center body and an inner side of the race and form together with the race and the bearing center body the rolling body or the sole holder.
Alternativ kann der Abrollkörper auf einer Welle gelagert sein, die den oberen Aufnahmearm und den unteren Aufnahmearm und den Abrollkörper durchragt, wobei das Lager in diesemAlternatively, the rolling body can be mounted on a shaft which projects through the upper receiving arm and the lower receiving arm and the rolling body, wherein the bearing in this
Fall zwischen der Welle und dem Abrollkörper im Bereich des Durchgriffs der Welle durch den Abrollkörper gebildet ist, sodass sich der Abrollkörper um die Welle drehen kann. Um zu verhindern, dass dabei der Abrollkörper direkt an dem oberen und/oder unteren Aufnahmearm anliegt, können zwischen dem oberen und unteren Aufnahmearm und der Ober- bzw. Unterseite des Abrollkörpers Abstandhalter angeordnet sein, die eine freie Drehung des Abrollkörpers um die Welle erlauben, ohne dass die freie Drehung durch Reibungskräfte an den Kontaktstellen zwischen den unteren und oberen Aufnahmearmen und der Ober bzw. Unterseite des Abrollkörpers behindert wird. Der Abstandhalter kann ein Federelement aufweisen, sodass der Abrollkörper minimal verkippen und/oder sich minimal nach oben bzw. unten bewegen kann. Dadurch kann beim Fahren eine Dämpfungswirkung bei der Übertragung von Schlägen die auf den Ski wirken auf den Skischuh erreicht werden.Case is formed between the shaft and the rolling body in the region of the passage of the shaft through the rolling body, so that the rolling body can rotate about the shaft. In order to prevent that the rolling body is applied directly to the upper and / or lower receiving arm, spacers can be arranged between the upper and lower receiving arm and the upper or lower side of the rolling body, which allow a free rotation of the rolling body around the shaft, without hindering the free rotation by frictional forces at the contact points between the lower and upper receiving arms and the upper and lower sides of the rolling body. The spacer may have a spring element, so that the rolling body can tilt slightly and / or can move slightly up or down. As a result, when driving a damping effect in the transmission of shock acting on the ski can be achieved on the ski boot.
Der Abrollkörper bzw. der Laufring bzw. der Sohlenhalter kann einen Überzug oder eine Ummantelung aus einem Kunststoff oder einem Leichtmetall aufweisen. Das Material wird bevorzugt so gewählt, dass ein Reibungswiderstand zwischen der Skisohle und dem Überzug oder der Ummantelung reduziert wird, sodass bei einer Querauslösung der Bindung, bei der der Abrollkörper bzw. der Außenring mit/ohne Überzug oder Ummantlung auf und/oder an der Skischuhsohle abrollt, die eingestellte Querauslösekraft der Bindung durch die wegfallende oder zumindest reduzierte Reibung zwischen dem Abrollkörper und der Skischuhsohle im Wesentlichen der tatsächlich auftretenden Querauslösekraft entspricht.The rolling body or the running ring or the sole holder may have a coating or a sheath made of a plastic or a light metal. The material is preferably chosen so that a frictional resistance between the ski sole and the cover or the sheath is reduced, so that in a transverse release of the binding in which the rolling body or the outer ring with / without coating or sheathing on and / or on the ski boot sole unwinds, the set transverse release force of the binding by the omitted or at least reduced friction between the rolling body and the ski boot sole essentially corresponds to the actual transverse release force occurring.
Der Überzug bzw. die Ummantelung kann auch elastische Eigenschaften aufweisen, sodass sich der Abrollkörper bzw. der Überzug oder die Ummantelung optimal an eine Oberfläche der Skischuhsohle in dem Bereich, indem der Abrollkörper den Skischuh auf den Ski spannt, anpassen kann. Dabei sollen diese elastischen Eigenschaften dem positiven Effekt des Abrollens des Sohlenhalters an der Skischuhsohle und der dadurch reduzierten Reibung nicht entgegenwirken.The cover or sheath may also have elastic properties, so that the rolling body or the cover or the sheath can optimally adapt to a surface of the ski boot sole in the region in which the rolling body biases the ski boot onto the ski. These elastic properties should not counteract the positive effect of unrolling the sole holder on the ski boot sole and the resulting reduced friction.
Die Erfindung gemäß dem Anspruch 8 umfasst weiterhin eine Spannvorrichtung für einen Skischuhhalter, bevorzugt einen Fersenhalter einer kombinierten Fahr- und Tourenbindung oder einer reinen Abfahrtsbindung, mit einem Verbindungselement zum Verbinden des Sohlenhalters mit der Spannvorrichtung oder einem Aufnahmearm der Spannvorrichtung, wobei der Sohlenhalter oder das Verbindungselement ein Kugel-, Tonnen- oder Nadellager umfasst, sodass sich der Sohlenhalter um das Verbindungselement drehen kann oder ein Laufring des Sohlenhalters sich um einen mit dem Verbindungselement drehsicher verbundenen Zentrumskörper des Sohlenhalters drehen kann. Bevorzugt handelt es sich bei dem Sohlenhalter um den bereits weiter oben beschriebenen Abrollkörper.The invention according to
Schließlich betrifft die Erfindung gemäß dem Anspruch 9 einen Sohlenhalter für ein Skihalteelement, der hergerichtet ist, um mit einem Sohlenhalter des Skihalteelements, bevorzugt eines Fersenhalters einer Skibindung, verbunden zu werden. Der Sohlenhalter umfasst ein Kugel-, Tonnen- oder Nadellager, sodass sich der Sohlenhalter um ein mit dem Spannvorrichtungskörper verbindbares Verbindungselement drehen kann. Alternativ bildet der Sohlenhalter selbst ein Drehlager mit einem Lagerzentralkörper, der drehfest mit einem Verbindungselement verbindbar ist und einem Laufring, der die quer zur Drehachse des Abrollkörpers weisende Flanke des Sohlenhalters bildet und sich um den Lagerzentralkörper drehen kann. Bevorzugt handelt es sich bei dem Sohlenhalter um den oben beschriebenen Abrollkörper.Finally, the invention according to
Die Erfindung umfasst ebenso gemäß dem Anspruch 10 einen Ski mit einem Fersenhalter mit dem oben beschriebenen Sohlenhalter.The invention also according to

Die
Der Fersenhalter 1 weist eine Verbindungsstruktur 3 auf, die mit der Basis 2 verbunden ist und eine Spannvorrichtung 4 mit einem Spannvorrichtungskörper 4a. An der Spannvorrichtung 4 sind zwei Steighilfen 7, 8 befestigt, die Spannvorrichtung 4 ist in einer Schwenkachse 9 schwenkbar mit der Verbindungstruktur 3 verbunden.The
Die Verbindungsstruktur 3 weist ein erstes Verbindungstrukturteil 3a und ein zweites Verbindungsstrukturteil 3b auf, die um die Achse A3 schwenkbar miteinander verbunden sind, sodass beim Auftreten großer Seitenkräfte die Bindung bzw. der Fersenhalter 1 den Skischuh durch ein Verschwenken des Verbindungsstrukturteils 3a relativ zum Verbindungstrukturteil 3b um die Schwenkachse A3 frei geben kann. Zur Einstellung der Auslösekraft der Querauslösung weist der Fersenhalter 1 eine nicht sichtbare Auslösevorrichtung auf, deren Auslösekraft durch eine Kulisse 12 mit vorgegeben ist.The connection structure 3 has a first
Die Spannvorrichtung 4 umfasst einen Sohlenhalter 5, der im Ausführungsbeispiel aus zwei Teilsohlenhaltern 5a und 5b besteht. Jeder der Teilsohlenhalter 5a, 5b ist als Abrollkörper 5a, 5b in Form einer Rolle oder Scheibe ausgebildet und ist in von dem Spannvorrichtungskörper 4a gebildeten Aufnahmearmen 15, 16 gelagert.The tensioning device 4 comprises a
Die
An dem vom Spannvorrichtungskörper 4a entfernten Ende weisen die oberen Aufnahmearme 15o, 16o und die unteren Aufnahmearme 15u, 16u je eine Bohrung, bevorzugt eine Durchgangsbohrung, auf, in die ein Stift 10 von oben eingeführt werden kann. Unterhalb des oberen Aufnahmearms 15o, 16o ist ein Abstandshalter 13 zu sehen, der ebenfalls von dem Stift 10 durchgriffen werden kann. Der Abstandshalter ist im Ausführungsbeispiel als Federelement 13 ausgebildet oder umfasst zumindest ein Federelement 13. Ein identischer Abstandhalter kann auch oberhalb des unteren Aufnahmearms 15u, 16u vorgesehen sein, ist in der
Bei dem Abrollkörper 5a, 5b handelt es sich im Ausführungsbeispiel um einen scheibenartigen Körper der sich im eingebauten Zustand um seine Drehachse A1 bzw. A2 drehen kann und so bei einer Seitenauslösung des Fersenhalters 1 an der Skischuhsohle abrollen kann, wodurch ein Reibungswiderstand zwischen der Skischuhsohle und dem Sohlenhalter 5 bei der Querauslösung zumindest reduziert wird.In the exemplary embodiment, the rolling
Damit sich der Abrollkörper 5a, 5b um seine Drehachse A1, A2 drehen kann, können der Stift 10 oder der Abrollkörper 5a, 5b im Bereich des Durchgriffs des Stifts 10 durch den Abrollkörper 5a, 5b ein Drehlager, z.B. ein Kugel-, Tonnen oder Nadellager aufweisen. Das Drehlager ist dabei z.B. am oder im Abrollkörper 5a, 5b am Innenumfang der Durchgangsöffnung oder am Stift 10 am Außenumfang im Bereich des Durchgriffs des Stifts 10 durch den Abrollkörper 5a, 5b gebildet.In order for the rolling
Alternativ kann der Abrollkörper 5a, 5b auch einen Lagerzentrumskörper 5a1, 5b1 und einen unverlierbar mit dem Lagerzentrumskörper 5a1, 5b1 verbundenen Laufring 5a2, 5b2 aufweisen, der den Außenumfang des Abrollkörpers 5a, 5b bildet. Bei dieser alternativen Ausführung ist der Lagerzentrumskörper 5a1, 5b1 mit dem Stift 10 so verbunden, dass sich der Lagerzentrumskörper 5a1, 5b1 relativ zu dem Stift 10 nicht um die Drehachse A1, A2 drehen kann. Die Drehung um die Drehachse A1, A2 findet bei dieser Ausführung zwischen dem stehenden Lagerzentrumskörper 5a1, 5b1 und dem um den Lagerzentrumskörper 5a1, 5b1 drehbaren Laufring 5a2, 5b2 statt. Bei dieser alternativen Ausführung kann der Stift 10 in den Lagerzentrumskörper 5a1, 5b1 nur eingreifen, er muss ihn nicht durchgreifen. Ebenfalls kann auf den unteren Aufnahmearm 15u, 16u verzichtet werden und auf den oder die Abstandshalter 13, was insbesondere bei der Verwendung des Fersenhalters 1 in Kinderbindungen zu einer Reduzierung des Gewichts und der Kosten führen kann.Alternatively, the rolling
Das Ergebnis der beschriebenen alternativen Ausführungen ist identisch, in allen Fällen kann der Abrollkörper 5a, 5b bei einer Querauslösung der Skibindung bzw. des Fersenhalters 1 auf der Schuhsohle abrollen.The result of the described alternative embodiments is identical, in all cases the rolling
Der Abrollkörper 5a, 5b kann eine Ummantelung 14 aufweisen, die aus einem Material besteht, das einen Rollwiderstand zwischen dem Abrollkörper 5a, 5b und der Skischuhsohle weiter reduziert und/oder elastisch ist, um sich einer Form der Skischuhsohle im Bereich des Eingriffs optimal anzupassen. Dieses Material kann ein Kunststoff oder ein Leichtmetall sein.The rolling
Die Ummantelung 14 kann mit dem Abrollkörper 5a, 5b so verbunden sein, dass die Ummantelung 14 vom Nutzer leicht ausgetauscht werden kann. So kann der Nutzer z.B. die Farbe oder das Design der Ummantelung 14 beliebig auswählen und durch Austausch die optische Erscheinung des Fersenhalters 1 beliebig verändern.The
