Description

Die Erfindung betrifft eine Lauffläche für einen Ski, insbesondere einen Langlaufski, bei welcher zumindest in Teilbereichen der Länge und Breite des Ski eine Vielzahl von Laufflächeneinschnitten in Form von in der Längsrichtung des Ski aufeinanderfolgenden abgestuften Rampen vorgesehen ist, die im Längsschnitt ein sägezahnartiges rückgleithemmendes Profil aufweisen.The invention relates to a tread for a ski, in particular a cross-country ski, in which, at least in partial areas of the length and width of the ski, a plurality of tread incisions are provided in the form of successive graded ramps in the longitudinal direction of the ski, which have a sawtooth-like anti-slip profile in longitudinal section .

Solche Stufenrampen dienen zur Erzielung eines Gleit-Abstoß-Effektes.Such step ramps are used to achieve a sliding repulsion effect.

Eine Lauffläche dieser Art ist durch die DE-PS 684.155 bekanntgeworden. Sie besitzt auf jeder Längshälfte in gewissem Abstand von ihrer Außenkante wenigstens eine Reihe von Auskehlungen in Form von hintereinander angeordneten Pfeilen, deren nach vorn gerichtete Spitzen auf einer gemeinsamen, am Ski längs laufenden Symmetrielinie liegen, die jede Auskehlung in zwei Symmetriehälften teilt, bei denen die Vertiefung an der Pfeilbasis beginnt und gegen die Pfeilspitze hin zunimmt.A tread of this type has become known from DE-PS 684.155. On each longitudinal half, at a certain distance from its outer edge, it has at least one row of grooves in the form of arrows arranged one behind the other, the tips of which point forward on a common line of symmetry running longitudinally on the ski, which divides each groove into two symmetry halves, in which the Deepening at the arrow base begins and increases towards the arrowhead.

Durch die AT-PS 360 884 ist eine Lauffläche bekanntgeworden, bei welcher über die Skibreite quer zur Längsachse des Ski jeweils mehrere Stufenrampen mit einem Mittelabstand in einer Reihe angeordnet sind und zwei in der Längsrichtung des Ski im Abstand aufeinanderfolgende Querreihen in der Querrichtung, vorzugsweise um den halben Mittelabstand, gegeneinander versetzt sind. Bei den bekannten Stufenrampen steigt die Oberfläche der durch die Stufenrampe gebildeten Mulde von der Stufenkante allmählich und kontinuierlich bis zur Laufflächenoberseite an.From AT-PS 360 884 a tread has become known in which several step ramps are arranged in a row with a central distance across the ski width transversely to the longitudinal axis of the ski and two transverse rows in the longitudinal direction of the ski at a distance in the transverse direction, preferably around half the center distance are offset from each other. In the known step ramps, the surface of the trough formed by the step ramp rises gradually and continuously from the step edge to the top of the tread.

Aufgabe der Erfindung ist die Schaffung von Maßnahmen, durch welche eine Verbesserung des Verhältnisses vom Abstoß- zum Gleitvermögen bei allen Schneebedingungen eintritt. Diese Aufgabe wird bei einer Lauffläche der eingangs erwähnten Art dadurch erreicht, daß erfindungsgemäß in dem in der Längsrichtung des Ski flach ansteigenden Bereich der Stufenrampe eine Sekundärstufe angeordnet ist, wobei die Abstoßkante der Sekundärstufe tiefer als die Abstoßkante der Stufenrampe liegt.The object of the invention is to provide measures by which there is an improvement in the ratio of repulsion to sliding ability in all snow conditions. These Task is achieved with a tread of the type mentioned in that, according to the invention, a secondary step is arranged in the region of the step ramp which rises gently in the longitudinal direction of the ski, the abutting edge of the secondary step being lower than the abutting edge of the step ramp.

Der Erfindungsgegenstand wird anhand der Zeichnung näher erläutert. Es zeigen

die Schneeverhältnisse in der Abstoßphase des Ski

in der Gleitphase, wobei jeweils ein Längsschnitt eines Teiles der Lauffläche dargestellt ist, und
Fig. 3

The object of the invention is explained in more detail with reference to the drawing. Show it
Fig. 1
the snow conditions in the push-off phase of the ski
Fig. 2
in the sliding phase, a longitudinal section of part of the tread being shown, and

Mit 1 ist ein Ski bzw. ein Laufflächenbelag bezeichnet, welcher eine Lauffläche 2 aufweist, in der im rechten Winkel zur Längsachse des Ski verlaufende sägezahnartige Stufenrampen 3 vorgesehen sind, welche Einschnitte bilden, die sich von einer Abstoßkante 4, an welcher die Einschnitte am tiefsten sind, ansteigend bis zur Lauffläche 2 erstrecken. Die Form der Profilierung kann beliebig gewählt sein. So besteht die Möglichkeit, die Stufenkante 4 geradlinig auszuführen, wie es beispielsweise die AT-PS 360 884 zeigt, oder gekrümmt, wie es beispielsweise die FR-PS 808 359 zeigt. Die einzelnen Stufenrampen 3 können sich über nur einen Teil der Breite der Gleitfläche erstrecken, wobei mehrere Stufenrampen, allenfalls mit einem Mittelabstand, in einer Reihe nebeneinander angeordnet sind. Es besteht aber auch die Möglichkeit, in der Reihe nur einen einzigen, sich im wesentlichen über die gesamte Skibreite erstreckende, Einschnitt vorzusehen, wie es beispielsweise die DE-OS 21 42 271 zeigt. Bei Anordnung mehrerer Stufenrampen in einer Reihe können einzelne Querreihen oder die aufeinanderfolgenden Querreihen in der Querrichtung zur Laufrichtung, z.B. um den halben Mittelabstand, gegeneinander versetzt angeordnet sein, wie dies beispielsweise bei der in Fig. 3 dargestellten Variante vorgesehen ist.1 with a ski or a tread surface is designated, which has a tread 2, in which sawtooth-like step ramps 3 are provided which run at right angles to the longitudinal axis of the ski and which form incisions which extend from a kick edge 4, at which the incisions are deepest are, extend ascending to the tread 2. The shape of the profiling can be chosen arbitrarily. So there is the possibility of executing the step edge 4 in a straight line, as shown, for example, by AT-PS 360 884, or curved, as shown, for example, by FR-PS 808 359. The individual step ramps 3 can extend over only part of the width of the sliding surface, a plurality of step ramps, at most with a central spacing, being arranged in a row next to one another. However, there is also the possibility of providing only a single incision in the row, which essentially extends over the entire width of the ski, as is shown, for example, by DE-OS 21 42 271. By arrangement of several step ramps in a row, individual transverse rows or the successive transverse rows in the transverse direction to the running direction, for example by half the center distance, can be arranged offset from one another, as is provided, for example, in the variant shown in FIG. 3.

Erfindungsgemäß besitzen alle oder nur einzelne Stufenrampen 3 eine Sekundärstufe 5 mit einer eigenen Abstoßkante 6, die im vorliegenden Falle tiefer als die Abstoßkante 4 der Stufenrampe 3 gelegen ist. Durch die erfindungsgemäße Doppelstufe wird, wie Fig. 1 erkennen läßt, in der Abstoßphase eine erhöhte Schneeflächenpressung erzielt, in welcher die Sekundärstufe 5 in den Schnee eindringen kann und somit zur Erhöhung des Abstoßwiderstandes bzw. der Haftreibung beiträgt. In der Gleitphase kommt die tieferliegende Sekundärstufe nicht in Schneekontakt, sodaß beim Gleiten keine Erhöhung der Gleitreibung entsteht. Mit Pfeil A ist die Bewegungsrichtung des Ski angedeutet. Hierbei sind die Schneekristalle mit 7 bezeichnet.According to the invention, all or only individual step ramps 3 have a secondary step 5 with its own kick edge 6, which in the present case is located lower than the kick edge 4 of the step ramp 3. As can be seen in FIG. 1, the double step according to the invention results in an increased snow surface pressure in the push-off phase, in which the secondary step 5 can penetrate the snow and thus contribute to increasing the push-off resistance or static friction. In the sliding phase, the lower-lying secondary stage does not come into contact with snow, so there is no increase in sliding friction when sliding. The direction of movement of the ski is indicated by arrow A. The snow crystals are denoted by 7.

Im Rahmen der Erfindung können die Stufenrampen in die Gleitfläche eines Ski eingearbeitet werden, es besteht aber auch die Möglichkeit, einen Laufflächenbelag mit den erfindungsgemäßen Stufenrampen zu versehen und eine solche Lauffläche auf beliebigen Ski anzubringen.In the context of the invention, the step ramps can be incorporated into the sliding surface of a ski, but it is also possible to provide a tread surface with the step ramps according to the invention and to attach such a tread on any ski.
