Description

Langlaufski mit SteiqhilfeCross-country skis with climbing aid
Technisches GebietTechnical field
Die Erfindung betrifft einen Langlaufski, mit einer im Längsmittelbereich der Lauffläche angeordneten Steighilfe, deren Oberfläche im Längsschnitt sägezahnförmig mit gegen die Laufrichtung geneigten Spitzen ausgebildet ist, welche im unbelasteten Zustand des Längs itteilbereichs durch eine Lagerschichte elastisch unterstützt aus der Laufflächenebene vorstehen und im belasteten Zustand gegen die elastische Unterstützung hinein¬ gedrückt sind.The invention relates to a cross-country ski, with a climbing aid arranged in the longitudinal central region of the tread, the surface of which is formed in a longitudinal section in a sawtooth shape with tips inclined against the direction of travel, which in the unloaded state of the longitudinal part thereof project elastically supported by a bearing layer from the tread plane and in the loaded state against the elastic support is pushed in.
Stand der TechnikState of the art
Bekannt ist, daß beim Gleiten mit einem Langlaufski der Fuß beim Ab¬ drücken vom Boden keinen wirklich festen Gegenpol findet. Je nach Be¬ schaffenheit des Schnees und des Langlaufskis gleitet letzterer dann auch rückwärts, was bis zu einem gewissen Grad durch einen Wachsauftrag bzw. durch Ausstattung des Skis mit sogenannten "Nowax-Belägen" verhindert werden kann.It is known that when gliding with a cross-country ski, the foot does not find a really strong opposite pole when it is pushed off the ground. Depending on the nature of the snow and the cross-country ski, the latter then also glides backwards, which can be prevented to a certain extent by applying wax or by equipping the ski with so-called "Nowax coverings".
Nowax-Beläge werden durch besondere Profilierungen der Lauffläche im Steigbereich des Langlaufskis gebildet und üblicherweise in einem zu¬ sammen mit der übrigen Lauffläche des Langlaufskis hergestellt. Ein Ski mit einem derartigen Belag muß in seinem Steigbereich nicht gewachst werden, wobei allerdings das Profil im Steigbereich beim Vorwärtsfahren einen bestimmten Widerstand leistet, der die Gleitfähigkeit des Skis reduziert. Bei häufigem Gebrauch des Langlaufskis nutzen sich weiters auch die Profilkanten dieser Nowax-Beläge ab und verlieren ihre Wirkung. Mit der abgenützten Steighilfe findet der Langläufer dann im Moment des Abstoßes wiederum keinen ausreichenden Widerstand.Nowax coverings are formed by special profiling of the running surface in the climbing area of the cross-country ski and are usually produced together with the rest of the running surface of the cross-country ski. A ski with such a covering does not have to be waxed in its climbing area, although the profile in the climbing area provides a certain resistance when driving forward, which reduces the sliding ability of the ski. If the cross-country ski is used frequently, the profile edges of these Nowax rubbers also wear out and lose their effect. With the worn climbing aid, the cross-country skier again does not find sufficient resistance at the moment of the push off.
Mit derartigen Steighilfen, welche in einem mit der Lauffläche herge¬ stellt werden, ist eine Erneuerung des Profiles nur beschränkt wieder¬ holbar und mit einem derartigen Aufwand verbunden, daß sie für einen durchschnittlichen Langläufer kaum in Frage kommt.With such climbing aids, which are produced in one with the tread, a renewal of the profile can only be repeated to a limited extent and is associated with such an effort that it is hardly possible for an average cross-country skier.
Weiters ist beispielsweise aus der AT-PS 388 302 ein Langlaufski der eingangs genannten Art bekannt, bei dem die Steighilfe aus einer Vielzahl sogenannter Rückgleit-Bremselemente besteht, die an der Skiunterseite über eine elastische Zwischenlage befestigt und aus einer eingeschwenkten Lage in eine ausgespreizte Stellung verschwenkbar sind. Eine Schwach¬ stelle dieser bekannten Konstruktion ist im Umstand zu sehen, daß die einzelnen Bremselemente je für sich auf der elastischen Schichte be¬ festigt, insbesonders auch geklebt sind, was in der rauhen Praxis des Langlaufskifahrens unweigerlich zu einer frühen Zerstörung der Steighilfe durch Steinchen, kleine Äste und dergleichen führt, die beim Einfedern der einzelnen Bremselemente festgehalten und eingeklemmt werden. Weiters sind auch die der elastischen Schicht zugewandten und damit zur Be¬ festigung zur Verfügung stehenden Oberflächenbereiche der Bremselemente relativ schmal, sodaß keine wirklich dauerhaft Befestigung möglich ist.Furthermore, a cross-country ski is from AT-PS 388 302, for example The type mentioned at the outset, in which the climbing aid consists of a large number of so-called sliding brake elements which are fastened to the underside of the ski via an elastic intermediate layer and can be pivoted from a pivoted-in position into an expanded position. A weak point of this known construction can be seen in the fact that the individual brake elements are each individually attached to the elastic layer, in particular also glued, which inevitably leads to early destruction of the climbing aid by stones in the harsh practice of cross-country skiing. leads small branches and the like, which are held and clamped when the individual brake elements deflect. Furthermore, the surface areas of the brake elements that face the elastic layer and are therefore available for fastening are relatively narrow, so that no really permanent fastening is possible.
Darstellung der ErfindungPresentation of the invention
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, einen Langlaufski der eingangs genannten Art so zu verbessern, daß Probleme der oben angesprochenen Art vermieden werden und insbesonders eine robuste und dauerhafte Ausbildung der Steighilfe, die beim Vorwärtsfahren einen annähernd so geringen Gleitwiderstand wie ein Ski ohne Steighilfe er¬ geben, andererseits jedoch beim Abdrücken vom Boden im Moment des Ab¬ stoßes eine optimale Griffig-keit bieten soll, ermöglicht wird.The present invention is therefore based on the object to improve a cross-country ski of the type mentioned in such a way that problems of the type mentioned above are avoided and in particular a robust and durable design of the climbing aid, which when driving forward has an almost as low sliding resistance as a ski without climbing aid result, but, on the other hand, should offer optimum grip when pushing off the ground at the moment of pushing off, is made possible.
Dies wird gemäß der vorliegenden Erfindung bei einem Langlaufski der eingangs genannten Art dadurch erreicht, daß die sägezahnförmige Ober¬ fläche der Steighilfe an einer einstückig durchgehenden Deckschichte ausgebildet ist, und daß die Deckschichte durchgehend mit der die elastische Unterstützung bildenden Lagerschichte verbunden ist.This is achieved in accordance with the present invention in a cross-country ski of the type mentioned at the outset in that the sawtooth-shaped surface of the climbing aid is formed on a one-piece cover layer and in that the cover layer is continuously connected to the bearing layer which forms the elastic support.
In besonders bevorzugter weiterer Ausgestaltung der Erfindung ist vor¬ gesehen, daß Deckschichte und Lagerschichte zusammen auswechselbar am Ski befestigt, vorzugsweise geklebt, sind.In a particularly preferred further embodiment of the invention, it is provided that the cover layer and bearing layer are interchangeably attached, preferably glued, to the ski.
Das Laufflächenprofil der Steighilfe ist also wiederum im Längsschnitt mit einem gegen die Laufrichtung gerichteten Kamm sägezahnförmig ge¬ schnitten und wird, vorzugsweise in Streifenform, in dem auf die Länge bezogenen mittleren Bereich des Skis der für die Übertragung der Kraft beim Abdrücken vom Boden im Moment des Abstoßens maßgeblich ist (Steig¬ bereich), in einem oder mehreren Teilen in leicht austauschbarer Weise, beispielsweise durch ein Klebeband auf der Rückseite der Steighilfe, eine einfache Steckvorrichtung, oder durch eine sonstige einfache mechanische oder chemische Befestigung, montiert und zwar in einer passenden Aus¬ nehmung auf der Lauffläche in die Tiefe des Untergurtes eingesetzt und befestigt. Damit ist unterschiedlich zum Aufbau des Skiuntergurtes im Steigbereich der ansonsten im wesentlichen ebenen Lauffläche des Lang¬ laufskis die Steighilfe dauerhaft so elastisch gelagert, daß einerseits im unbelasteten Zustand die sägezahför ig geschnittene Lauffläche der Steighilfe gegenüber der anderen Lauffläche in etwa um die lichte Höhe der Sägezähne erhaben ist und andererseits im belasteten Zustand beim Vorwärtsfahren die tiefsten Punkte der Steighilfe, nämlich die Spitzen und Grate, unter Verminderung des Gleitwiderstandes der Steighilfe in die ansonsten vorliegende Laufflächenebene gedrückt werden, während im Moment des Abstoßens die Steighilfe aufgrund der erwähnten Ausbildung und elastischen Lagerung sowie der gegen die Laufrichtung gerichteten Kraft im Moment des Abdrückens vom Boden über die sonstige Laufflächenebene herausgezogen wird, womit sich die Spitzen und Grate im Schnee der Langlaufspur verkrallen können.The tread pattern of the climbing aid is again cut in a saw-tooth shape in longitudinal section with a comb directed against the direction of travel and is, preferably in strip form, in the central region of the ski, which is related to the length, for the transmission of the force is decisive when pushing off the ground at the moment of pushing off (climbing area), in one or more parts in an easily replaceable manner, for example by means of an adhesive tape on the back of the climbing aid, a simple plug-in device, or by some other simple mechanical or chemical fastening, assembled and inserted and fastened in a suitable recess on the tread in the depth of the lower flange. Thus, in contrast to the structure of the lower ski belt in the climbing area of the otherwise essentially flat running surface of the cross-country ski, the climbing aid is permanently resiliently mounted so that, on the one hand, in the unloaded state, the tread cut of the saw aid, compared to the other running surface, approximately by the clear height of the saw teeth is raised and, on the other hand, in the loaded state when driving forward, the deepest points of the climbing aid, namely the tips and ridges, are pressed into the otherwise existing tread plane while reducing the sliding resistance of the climbing aid, while at the moment of pushing off the climbing aid due to the mentioned training and elastic mounting as well the force directed against the direction of travel is pulled out of the ground over the other tread plane at the moment of pulling, with which the peaks and ridges can cling to the snow of the cross-country trail.
Die im Längsschnitt sägezahnförmige Oberfläche der Steighilfe ist also an einer einstückig durchgehenden Deckschichte ausgebildet, welche durch¬ gehend mit der die elastische Unterstützung bildenden Lagerschichte verbunden ist, womit Probleme der eingangs angesprochenen Art gänzlich vermieden werden und eine robuste und dauerhafte Steighilfe erhalten wird. Die einstückig durchgehende Ausbildung der im Längsschnitt säge- zahnförmigen Oberfläche der Steighilfe ansich ist beispielsweise auch von den eingangs angesprochenen "Nowax-Belägen" her bekannt, wobei diese aber natürlich keine elastische Unterstützung oder dergleichen aufweisen.The surface of the climbing aid, which is sawtooth-shaped in longitudinal section, is therefore formed on a one-piece, continuous covering layer which is continuously connected to the bearing layer forming the elastic support, with which problems of the type mentioned at the outset are completely avoided and a robust and durable climbing aid is obtained. The continuous, one-piece design of the sawtooth-shaped surface of the climbing aid itself is also known, for example, from the "Nowax coverings" mentioned at the outset, but of course these have no elastic support or the like.
