Abstract

A heel-holding device for cross-country and touring skiing boots releases the boot in directions transverse to the longitudinal axis of the ski and in the vertical direction when predetermined release values are exceeded. Through a special design and selection of materials, the number of separated parts of the binding have been minimized.

Description

Absatzhaltevorrichtung für Langlauf- und Tourenskischuhe Heel holder for cross-country and touring ski shoes
Die Anmeldung bezieht sich auf eine Absatzhaltevorrichtung für Langlauf- und Tourenskischuhe, wie sie zum Beispiel aus der DE 34 37143 C 1 bekannt ist.The application relates to a heel holding device for cross-country and touring ski shoes, as is known for example from DE 34 37143 C1.
Die in DE 34 37 143 C 1 beschriebene Absatzhaltevorrichtung bietet dem Langläufer bei normaler Witterung in schwierigem Gelände den gewünschten Halt auf den Langlaufskiern, um mit ihnen gewünsche Richtungsänderungen, wie Pflugbogen, Seitrutschen und ähnliche Manöver durchführen zu können. Bei entsprechender seitlicher oder vertikaler Überlastung gibt die Absatzhaltevorrichtung den Schuh frei. Bei Temperaturschwankungen, die in die Plus- und Minus-Grade gehen, neigt die Bindung durch ihren komplizierten Aufbau zum Vereisen. Dabei wird die Sicherheitsfunktion der Absatzhaltevorrichtung teilweise außer Kraft gesetzt.The heel holding device described in DE 34 37 143 C 1 offers the cross-country skier the desired hold on the cross-country skis in normal weather in difficult terrain in order to be able to carry out desired changes in direction, such as plow arches, side slides and similar maneuvers. If there is a corresponding lateral or vertical overload, the heel holding device releases the shoe. With temperature fluctuations that go into the plus and minus degrees, the binding tends to freeze due to its complicated structure. The safety function of the heel holding device is partially overridden.
Aufgabe der Neuentwicklung ist eine Absatzhaltevorrichtung, die die Vorteile der in DE 34 37 143 C 1 beschriebenen aufweist, deren Nachteile durch Neukonstruktion und entsprechende Materialauswahl beseitigt werden. Ein weiteres Ziel war die Verringerung der notwendigen Einzelteile, um die Absatzhaltevorrichtung preislich günstiger herstellen zu können. The task of the new development is a heel holding device which has the advantages of that described in DE 34 37 143 C 1, the disadvantages of which are eliminated by new construction and appropriate choice of material. Another goal was to reduce the number of individual parts required to manufacture the heel holder at a lower price.
Wie bereits vorher erwähnt, neigt die in DE 34 37 143 C 1 beschriebene Absatzhaltevorrichtung sehr stark zum Vereisen. Das betrifft besonders die Wickelfeder des Halteteiles sowie die Druckfeder und den Schnappverschluß. Um derartige Schwierigkeiten auszuschließen, wurde bei der Neuentwicklung auf Federn gänzlich verzichtet. Diese Aufgabe wurde folgendermaßen gelöst. Die Absatzhaltevorrichtung besteht im wesentlichen ausAs previously mentioned, the heel holding device described in DE 34 37 143 C 1 tends to freeze very strongly. This applies particularly to the coil spring of the holding part as well as the compression spring and the snap lock. In order to avoid such difficulties, springs were completely dispensed with in the new development. This task was solved as follows. The heel holding device consists essentially of
einer Haltevorrichtung für das Schuhende, bestehend aus einer Grundplatte mit einstellbarer Klemmvorrichtung, einem Halte-Element für den am Schuh befindlichen Sohlenvorsprung und einem Federbügel oder einer Wippe, sowie einer drehbaren, federnden oder federbeaufschlagten Platte mit einem Keil oder Kegel, der in die mittig liegende Schuhsohlenaussparung greift.a holding device for the shoe end, consisting of a base plate with adjustable clamping device, a holding element for the sole protrusion on the shoe and a spring clip or a rocker, as well as a rotatable, resilient or spring-loaded plate with a wedge or cone, which lies in the middle Shoe sole recess engages.
Durch geeignete Materialauswahl und entsprechende Formgebung werden die erforderlichen Federfunktionen der Fersenhalterung und die Druckbeaufschlagung der Drehplatte durch die Absatz-Fersenhaltevorrichtung direkt übernommen. Die Drehplatte wird durch einen federnden Gehäusefortsatz , der in seiner Härte durch eine Vorrichtung verstellbar ist, federbeaufschlagt. Das als vorgebogene Feder ausgebildete Oberteil der Absatzhaltevorrichtung übernimmt in entriegelter Stellung (Abb.1) die Eückholung des Halteelements . Das Fersenteil des Schuhs kann ungehindert in der für den Langlauf notwendigen Sichtung bewegt werden. Bei Druσkbeaufschlagung des Federbügels durch den Skistock oder durch den zweiten Ski verformt sich dieser in eine Strecklage und rastet in eine vorgesehene Klemmvorrichtung ein. Bei dieser Streckbewegung wird das Halteelement in Sichtung Sohlenende geschoben. Es verriegelt dabei das Sohlenende des Schuhs (Abbildung 2).The required spring functions of the heel holder and the pressurization of the turntable are directly taken over by the heel holding device through a suitable material selection and appropriate shaping. The rotating plate is spring-loaded by a resilient housing extension, the hardness of which is adjustable by a device. The upper part of the heel holding device, designed as a pre-bent spring, takes over the retrieval of the holding element in the unlocked position (Fig. 1). The heel part of the shoe can be moved freely in the sighting necessary for cross-country skiing. When pressure is applied to the spring clip by the ski pole or by the second ski, the latter deforms into an extended position and engages in an intended clamping device. During this stretching movement, the holding element is pushed towards the end of the sole. It locks the sole end of the shoe (Figure 2).
Bei zur Skioberfläche nach oben auftretenden Kräften, wie sie bei Frontalstürzen entstehen, drückt das Haltelement in Richtung Skiende auf den unter Spannung stehenden Federbügel. Bei einem vorgegebenen Wert, der mit einer Einstellvorrichtung einstellbar ist, wird bei einer zur Skioberfläche wirkenden Druckbelastung der Federbügel vom Halteelement aus der Klemmvorrichtung gedrückt. Das Halteelement kippt in Sichtung Skiende weg und gibt so den Schuh frei. Der Auslösewert der Absatzhaltevorrichtung wird so eingestellt, daß bei Gleitphasen des Läufers auch jederzeit Schwünge und Bögen gefahren werden können. Nach Ende der Gleitphase wird der eingestellte Auslösewert mit dem Schuh geöffnet. Der Federbügel springt aus der Klemmvorrichtung und zieht das Halteelement in Richtung Skiende weg. Der Skiläufer kann nach der Gleitphase ohne weitere Betätigung der Ab satzhalt evorri chtung in den normalen Laufstil überwechseln.In the event of forces occurring upwards towards the ski surface, such as those which occur in the event of a head-on fall, the holding element presses in the direction of the ski end onto the spring clip which is under tension. At a predetermined value, which can be set with an adjusting device, the spring clip is released from the holding element when the pressure is applied to the ski surface the clamping device pressed. The holding element tilts away towards the end of the ski, thus releasing the shoe. The release value of the heel-holding device is set in such a way that turns and arches can also be made at any time during sliding phases of the runner. At the end of the sliding phase, the set trigger value is opened with the shoe. The spring clip jumps out of the clamping device and pulls the holding element towards the end of the ski. After the gliding phase, the skier can switch to the normal running style without further actuation of the heel stop.
Bei normalem Aussteigen aus der Absatzhaltevorrichtung werden mit dem Skistock oder per Hand die Wangen der Klemmvorrichtung durch den Keil auseinandergedrückt. Dabei springt der Federbügel in seine Ruhestellung. Die Haltevorrichtung ist entriegelt.When getting out of the heel holding device normally, the cheeks of the clamping device are pressed apart by the wedge with the ski stick or by hand. The spring clip jumps to its rest position. The holding device is unlocked.
Der Altexnativ-Vorschlag c) ist ähnlich aufgebaut wie in Vorschlag b) beschrieben. Der Unterschied zu b) besteht darin, daß der Bügel als Wippe ausgearbeitet ist. Durch Druckbeaufschlagung des Bügels vor dem Achspunkt (Richtung Skispitze) wird die Bindung verriegelt. Durch Druckbeaufschlagung des Bügels hinter dem Druckpunkt (Richtung Skiende) wird die Bindung entriegelt. Alle anderen Funktionen sind in Punkt b) bereits beschrieben. The old alternative proposal c) is structured similarly to that described in proposal b). The difference to b) is that the bracket is designed as a seesaw. The binding is locked by pressurizing the bracket in front of the axis point (towards the ski tip). The binding is unlocked by pressurizing the bracket behind the pressure point (towards the end of the ski). All other functions are already described in point b).
Funktionsbeschreibung eines möglichen Ausführungsbeispieles, das in den beiliegenden Zeichnungen von Fig. 1-6 dargestellt ist.Functional description of a possible embodiment, which is shown in the accompanying drawings of Figs. 1-6.
Die Absatzhalteyorrichtung mit drehbarer Platte und Keil für die Schuhsohlenaussparung ist auf dem Ski so montiert, daß der Haltebügel (5) in Ruhestellung den als Keil ausgebildeten Sohlenfortsatz nicht behindert. Eine normale Laufbewegung ist so gewährleistet. In schwierigem Gelände, hauptsächlich bei Gleitphasen, hat nun der Langläufer die Möglichkeit, durch Drücken des Gehäuseoberteils (2) den Schuh im Fersenbereich fest auf dem Ski zu fixieren. Durch diese Fixierung wird aus der LL-Bindung eine leichte Alpihbindung, die bei seitlicher oder vertikaler Überschreitung des eingestellten Auslösewertes den Schuh wieder frei gibt. Fach Beendigung der Gleitphase kehrt der Haltebügel (5) durch Anheben der Ferse wieder in seine Ruhestellung zurück. Der gleiche Vorgang kann auch durch Drücken des Entriegelungskeils (10) erreicht werden. The heel holding device with a rotatable plate and wedge for the shoe sole recess is mounted on the ski in such a way that the holding bracket (5) in the rest position does not hinder the sole extension designed as a wedge. A normal running movement is guaranteed. In difficult terrain, mainly during gliding phases, the cross-country skier can now fix the shoe firmly on the ski in the heel area by pressing the upper part of the housing (2). This fixation turns the LL binding into a light alpine binding, which releases the shoe when the set release value is exceeded laterally or vertically. At the end of the sliding phase, the retaining bracket (5) returns to its rest position by lifting the heel. The same process can also be achieved by pressing the unlocking wedge (10).
