Description

Die Erfindung betrifft einen kurzen Ski für je einen Fuß eines Skiläufers gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a short ski for one foot of a skier according to the preamble of claim 1.

Ein derartiger Ski ist z. B. bekannt aus der CH-A-504 877 oder US-A-3,854,739. Man nennt diese Art von Ski auch "Firngleiter" bzw. "Figl". Ein "Firngleiter" bzw. "Figl" weist bei einer über die Länge etwa konstanten Breite von 11,5 cm bis 12,5 cm eine Länge von 65 cm bis 75 cm auf. Dementsprechend liegt das Verhältnis zwischen Breite und Länge zwischen 0,15 und 0,19. In der Regel werden Firngleiter in einer sogenannten Compound-Sandwich-Konstruktion hergestellt, wie sie auch für Alpinski üblich ist. Die Herstellung aus Vollkunststoff oder Aluminium ist ebenfalls bekannt. "Firngleiter" bzw. "Figl" sind, wie bereits die Bezeichnung erkennen läßt, besonders gut zum Abfahren auf Firnschnee geeignet. Im übrigen, insbesondere zum Abfahren auf Pisten, sind Firngleiter praktisch nicht beherrschbar, da ihnen jegliche Spurtreue fehlt.Such a ski is e.g. B. is known from CH-A-504 877 or US-A-3,854,739. This type of ski is also called "firng glider" or "Figl". A "firng glider" or "Figl" has a length of 65 cm to 75 cm with a width of approximately 11.5 cm to 12.5 cm which is approximately constant over the length. Accordingly, the ratio of width to length is between 0.15 and 0.19. As a rule, firing gliders are manufactured in a so-called compound sandwich construction, which is also common for alpine skis. The production from all-plastic or aluminum is also known. "Firngleiter" or "Figl" are, as the name suggests, particularly well suited for skiing on firn snow. Otherwise, especially for skiing on slopes, snow gliders are practically unmanageable because they lack any directional stability.

Aus der CA-A-1,201,480 ist ein in üblicher Weise taillierter Alpinski bekannt. Die bekannte Taillierung mit einem Radius von mehreren Metern führt bei einem Kurzski der hier fraglichen Art zu nahezu geradlinigen Seiten mit der Folge, daß dem Kurzski jegliche Spurtreue fehlt. Auch ist es mit einem solchen Ski praktisch unmöglich, in herkömmlicher Weise zu schwingen.A custom-fitted alpine ski is known from CA-A-1,201,480. The well-known waist with a radius of several meters leads to almost straight sides with a short ski of the type in question, with the result that the short ski lacks any directional stability. With such a ski, it is practically impossible to swing in a conventional manner.

In der CH-A-595,118 ist ein Slalomski beschrieben, dessen Schaufel asymmetrisch ausgebildet ist, um die Gefahr des Einfädelns an den Torstangen zu verringern. Der bekannte Ski ist aber speziell für den Slalomsport ausgebildet.In CH-A-595,118 a slalom ski is described, the blade of which is asymmetrical in order to reduce the risk of threading on the gate bars. The well-known ski is specially designed for slalom sports.

Aus der DE-A-3,200,383 ist schließlich noch ein Alpinski bekannt, dessen Schaufel mit mehreren Längsschlitzen versehen ist, um die Führungseigenschaften beim verkanteten Fahren zu verbessern.Finally, from DE-A-3,200,383 an alpine ski is known, the shovel of which is provided with a plurality of longitudinal slots in order to improve the guiding properties when driving at an angle.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen kurzen Ski der eingangs genannten Art zu schaffen, welcher sich sowohl durch hohe Drehfreudigkeit als auch hohe Spurtreue auszeichnet, so daß er vielseitig verwendbar ist, insbesondere auch für Anfänger bei unterschiedlichsten Schneeverhältnissen.The present invention has for its object to provide a short ski of the type mentioned, which is characterized both by high turning ability and high directional stability, so that it is versatile, especially for beginners in a variety of snow conditions.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Dementsprechend ist zur Lösung der gestellten Aufgabe zum einen die Taillierung des mittleren Abschnitts von Bedeutung. Dadurch wird trotz der extremen Kürze des Ski eine hohe Spurtreue bei hoher Dreh- und Schwingfreudigkeit erhalten. Dabei ist überraschend, daß durch die relativ einfache Maßnahme einer ausgeprägten Taillierung der vorgenannte Vorteil erhalten wird.This object is achieved by the characterizing features of patent claim 1. Accordingly, the waist of the middle section is important for solving the task. Despite the extreme shortness of the ski, this ensures a high level of directional stability with a high degree of turning and vibration. It is surprising that the relatively simple measure of a pronounced waist gives the aforementioned advantage.

Zum anderen ist von Bedeutung die asymmetrisch ausgebildete Schaufel. Diese erlaubt ein Abrollen des vorderen Abschnitts des Ski beim normalen Gehen oder Laufen auf nicht gleitfähigem Untergrund, ähnlich wie das Abrollen des menschlichen Fußes. Des weiteren wird durch die Verlagerung der Schaufelspitze nach innen die Innenkante relativ zu der eines herkömmlichen "Firngleiters" gleicher Länge verlängert, wodurch eine erheblich bessere Fahreigenschaft, insbesondere Laufruhe des Ski bei vergleichsweise kurzer Länge erreicht wird. Des weiteren werden durch die Verlängerung der Schaufelspitzen nach innen beim Fahren im Schnee beide Ski durch den Schnee nach innen, d.h. aufeinander zu in enge Parallellage gedrängt. Auch dies trägt zu einer verbesserten Fahreigenschaft bei.The asymmetrical blade is also important. This allows the front section of the ski to roll when walking or running normally on a non-slippery surface, similar to the rolling of the human foot. Furthermore, by shifting the tip of the blade inwards, the inner edge is lengthened relative to that of a conventional "glider" of the same length, which results in significantly better skiing properties, in particular smooth running of the ski with a comparatively short length. Furthermore, by extending the shovel tips inwards when skiing in the snow, both skis are pushed inwards by the snow, ie towards one another in a narrow parallel position. This also contributes to an improved driving quality.

Vorteilhafte konstruktive Weiter- und Ausbildungen des erfindungsgemäßen Ski sind in den Unteransprüchen beschrieben, wobei noch besonders hervorzuheben wären die Maßnahmen nach Anspruch 2. Der in Draufsicht halbkreisförmig abgerundete hintere Abschnitt gemäß Anspruch 2 trägt ebenfalls ganz erheblich zur Drehfreudigkeit des Ski bei, wobei bei Rücklage auf der abgerundeten Hinterkante ohne Beeinträchtigung der Drehfreudigkeit gefahren werden kann.Advantageous design and further developments of the ski according to the invention are described in the subclaims, the measures according to claim 2 should also be particularly emphasized. The rear section, which is rounded in a semicircular shape in plan view, also contributes quite considerably to the turning ability of the ski, with a reserve the rounded rear edge can be driven without impairing the ability to turn.

Dementsprechend stellt die beanspruchte Dimensionierung sowie Formgebung einen idealen Kompromiß dar, mit welchem ein neuartiges Sportgerät geschaffen ist, welches sowohl Anfänger als auch Spitzenskifahrer anspricht.Accordingly, the claimed dimensions and shape represent an ideal compromise, with which a new type of sports equipment is created, which appeals to both beginners and top skiers.

Schließlich sind von besonderer Bedeutung noch die Maßnahmen nach Anspruch 9, wonach der vordere, schaufelartig nach oben gebogene Abschnitt mindestens einen sich etwa in Längsrichtung des Ski erstreckenden Einschnitt aufweist, wobei die einzelnen Schaufelabschnitte hinsichtlich der Biegesteifigkeit unterschiedlich eingestellt werden können.Finally, of particular importance are the measures according to claim 9, according to which the front, blade-like upwardly curved section has at least one cut extending approximately in the longitudinal direction of the ski, the individual blade sections being able to be set differently with regard to the bending stiffness.

Für das Laufen auf nicht gleitfähigem Untergrund einerseits und gleitendem Schnee andererseits sind auch die Merkmale des Anspruches 16 von besonderer Bedeutung. Durch diese Maßnahmen sind sowohl eine ausreichende Steifigkeit für das Fahren auf Schnee als auch eine ausreichend große Biegeelastizität für das Laufen auf nicht gleitfähigem Untergrund gewährleistet.The features of claim 16 are of particular importance for running on non-slippery ground on the one hand and sliding snow on the other. These measures ensure both sufficient rigidity for driving on snow and sufficient bending elasticity for running on non-slippery surfaces.

Der neuartige Ski läßt sich ähnlich wie ein Kurzski einerseits und ein "Firngleiter" andererseits fahren, wobei er bezüglich seiner Fahreigenschaften deutlich zwischen diesen beiden Extremen liegt und damit auch wesentlich vielseitiger einsetzbar ist.The new type of ski can be driven similarly to a short ski on the one hand and a "fir glider" on the other hand, whereby its skiing characteristics lie clearly between these two extremes and is therefore also much more versatile.

Nachstehend wird eine Ausführungsform eines erfindungsgemäßen Ski anhand der beigefügten Zeichnung näher erläutert. Es zeigen:

An embodiment of a ski according to the invention is explained in more detail below with reference to the attached drawing. Show it:
Fig. 1
a ski in top view;
Fig. 2
a ski of FIG. 1 in side view.

Dementsprechend besteht der in den Fig. 1 und 2 dargestellte kurze Ski aus einem brettartigen hinteren Abschnitt 10, mittleren Abschnitt 11 und vorderen Abschnitt 12, wobei letzterer schaufelartig nach oben gebogen ist, ähnlich wie bei herkömmlichen Alpin- und/oder Langlaufski. An der Oberseite des mittleren Abschnitts 11 ist eine nicht näher dargestellte Vorrichtung bzw. Bindung zur Fixierung des Schuhs eines Benutzers montierbar, und zwar in einem Bereich 13, der sich entsprechend Fig. 2 unmittelbar an die den Skikörper in zwei etwa gleich große vordere und hintere Hälften aufteilenden Trennlinie in Richtung zum hinteren Abschnitt 10 hin anschließt. Als Bindung kann eine herkömmliche Alpinski-Bindung oder eine Tourenbindung verwendet werden. Es ist auch die Montage einer Bindung denkbar, die zur Fixierung sowohl von festen Skischuhen als auch von flexiblen Wanderschuhen geeignet ist.Accordingly, the short ski shown in FIGS. 1 and 2 consists of a board-like rear section 10, middle section 11 and front section 12, the latter being bent upward like a shovel, similar to conventional alpine and / or cross-country skis. On the top of the middle section 11, a device or binding (not shown in more detail) for fixing the shoe of a user can be mounted, in a region 13 which, according to FIG. 2, directly adjoins the ski body in two approximately equal front and rear Halves dividing dividing line towards the rear section 10 connects. A conventional alpine binding or a touring binding can be used as binding. It is also conceivable to mount a binding that is suitable for fixing both firm ski boots and flexible hiking boots.

An der Unterseite sowohl des hinteren als auch mittleren und vorderen Abschnitts 10, 11, 12 ist eine Lauffläche 14 aus Kunststoff, insbesondere Polyethylen, Polyamid oder Mischungen davon, ausgebildet. Wie Fig. 1 erkennen läßt, sind die Seiten 15, 16 des mittleren Abschnitts 11 tailliert ausgebildet.A tread 14 made of plastic, in particular polyethylene, polyamide or mixtures thereof, is formed on the underside of both the rear and the middle and front sections 10, 11, 12. As can be seen in FIG. 1, the sides 15, 16 of the central section 11 are designed to be tailored.

Die maximale Projektionslänge "L", d.h. die maximale Länge in Draufsicht-Projektion, beträgt zwischen etwa 63 cm bis etwa 80 cm, insbesondere zwischen etwa 70 cm und etwa 75 cm. Eine besonders geeignete Länge ist 64,0 bis 65,0 cm.The maximum projection length "L", ie the maximum length in plan view projection, is between approximately 63 cm to approximately 80 cm, in particular between approximately 70 cm and approximately 75 cm. A particularly suitable length is 64.0 to 65.0 cm.

Wie Fig. 1 des weiteren erkennen läßt, beträgt das Verhältnis zwischen minimaler Breite "B", die der maximalen Taillierung im mittleren Abschnitt 11 entspricht, und maximaler Länge "L" etwa 0,12 bis etwa 0,23, insbesondere etwa 0,13 bis etwa 0,16. Der vordere Abschnitt 12 ist bei der dargestellten Ausführungsform der Abschnitt maximaler Breite, während die Breite des hinteren Abschnitts 10 zwischen der minimalen Breite "B" im Bereich des mittleren Abschnitts 11 und der maximalen Breite im Bereich des vorderen Abschnitts 12 liegt. Bei einer Ausführungsform beträgt die maximale Breite des vorderen Abschnitts 12 etwa 12 bis 14 cm, insbesondere etwa 13 cm, während die Breite des hinteren Abschnitts 10 etwa 10 bis 12 cm, insbesondere etwa 11 cm ist.As can also be seen in FIG. 1, the ratio between the minimum width "B", which corresponds to the maximum waist in the central section 11, and the maximum length "L" is approximately 0.12 to approximately 0.23, in particular approximately 0.13 to about 0.16. In the embodiment shown, the front section 12 is the section of maximum width, while the width of the rear section 10 lies between the minimum width "B" in the area of the middle section 11 and the maximum width in the area of the front section 12. In one embodiment, the maximum width of the front section 12 is approximately 12 to 14 cm, in particular approximately 13 cm, while the width of the rear section 10 is approximately 10 to 12 cm, in particular approximately 11 cm.

Der mittlere taillierte Abschnitt 11 weist eine Länge auf, die hier etwa 75 % der gesamten Projektionslänge "L" entspricht. Auch diese Dimensionierung hat sich als besonders zweckmäßig erwiesen.The center waisted section 11 has a length which here corresponds to approximately 75% of the total projection length "L". This dimensioning has also proven to be particularly useful.

Wie Fig. 2 erkennen läßt, ist der mittlere Abschnitt 11 nach oben vorgespannt, so daß im unbelasteten Zustand die Lauffläche 14 vom ebenen Boden 17 einen gewissen Abstand "H" aufweist, und zwar in einer Größenordnung von 1,0 bis 6,0 mm, insbesondere etwa 2,0 mm.As can be seen in FIG. 2, the middle section 11 is prestressed upward, so that in the unloaded state the tread 14 is at a certain distance "H" from the flat floor 17, in the order of magnitude of 1.0 to 6.0 mm , in particular about 2.0 mm.

Der vordere, schaufelartig nach oben gebogene Abschnitt 12 umfaßt 5 "Zehen", wobei zwischen den drei größeren "Zehen" jeweils ein längerer Einschnitt 19 ausgebildet ist, der sich etwa in Längsrichtung des Ski erstreckt. Dadurch entsteht eine Art multiflexible Spitze bzw. Schaufel. Die Einschnitte 19 können auch bis zu den "Zehenwurzeln" ausgebildet sein. Die beiden kleineren "Zehen" können zu einer einzigen größeren, nämlich breiteren "Zehe" zusammengefaßt sein.The front section 12, which is curved like a shovel, comprises 5 "toes", a longer incision 19 being formed between the three larger "toes" and extending approximately in the longitudinal direction of the ski. This creates a kind of multi-flexible tip or scoop. The incisions 19 can also be formed up to the "toe roots". The two smaller "toes" can be combined into a single larger, namely wider "toe".

Seitlich ist die Lauffläche 14 durch nicht näher dargestellte Stahlkanten begrenzt.Laterally, the tread 14 is limited by steel edges, not shown.

Wie bereits oben dargelegt, kann der mittlere Abschnitt 11 auch eben oder geringfügig (1 bis 4 mm) nach unten vorgespannt bzw. gewölbt sein. Dadurch wird der Ski besonders drehfreudig und für Anfänger besonders gut geeignet. Die Lauffläche 14 kann auch noch mindestens eine Längsführungsrille in an sich bekannter Weise aufweisen, um die Spurtreue zu erhöhen. Grundsätzlich ist eine derartige Längsführungsrille jedoch entbehrlich aufgrund der Taillierung des mittleren Abschnitts 11. Zu diesem Zweck ist wenigstens jeweils die im montierten Zustand innenliegende Seite (hier Seite 16) des mittleren Abschnitts 11 tailliert bzw. konkav gewölbt ausgebildet.As already explained above, the middle section 11 can also be biased flat or slightly (1 to 4 mm) downwards or curved. This makes the ski particularly easy to turn and particularly suitable for beginners. The tread 14 can also have at least one longitudinal guide groove in a manner known per se in order to increase the directional stability. In principle, however, such a longitudinal guide groove can be dispensed with due to the waist of the middle section 11. For this purpose, at least the inner side (here page 16) of the middle section 11 in the assembled state is designed to be waisted or concave.

Entsprechend Fig. 1 ist der hintere Abschnitt 10 in Draufsicht etwa halbkreisförmig abgerundet. Des weiteren ist der hintere Abschnitt 10 geringfügig nach oben gebogen. Dadurch wird beim Schwingen oder auch "Tanzen" ein Verhaken im Untergrund bzw. Schnee verhindert.1, the rear section 10 is rounded off approximately semicircular in plan view. Furthermore, the rear section 10 is slightly bent upwards. This prevents jamming in the ground or snow when swinging or "dancing".

Entsprechend Fig. 1 ist der mittlere Abschnitt 11 symmetrisch tailliert, wobei der Radius der Taillierung in Richtung vom vorderen 12 zum hinteren Abschnitt 10 zunimmt. Die Seiten-Taillierung des mittleren Abschnitts 11 ist durch zwei Radien R1 und R2 definiert, wobei der Radius R2 des an den hinteren Abschnitt 10 angrenzenden Teils der seitlichen Begrenzung des mittleren Abschnitts größer, insbesondere nahezu doppelt so groß wie der Radius R1 des an den vorderen Abschnitt 12 angrenzenden Teils der seitlichen Begrenzung des mittleren Abschnitts 11 ist.According to FIG. 1, the middle section 11 is fitted symmetrically, the radius of the waist increasing in the direction from the front 12 to the rear section 10. The side waist of the central section 11 is defined by two radii R1 and R2, the radius R2 of the part of the lateral boundary of the central section adjoining the rear section 10 being larger, in particular almost twice as large as the radius R1 of the front section Section 12 adjacent part of the lateral boundary of the middle section 11.

Der Radius R3 bzw. R4 sowohl des nach oben gebogenen vorderen Abschnitts 12 als auch des nach oben gebogenen hinteren Abschnitts 10 beträgt etwa 20 bis 30 cm, insbesondere etwa 20 bis 24 cm.The radius R3 or R4 of both the upwardly curved front section 12 and the upwardly curved rear section 10 is approximately 20 to 30 cm, in particular approximately 20 to 24 cm.

Der Abstand des freien Endes des nach oben gebogenen Abschnitts 12 vom ebenen Boden 17 beträgt etwa 3,0 bis 4,0 cm, insbesondere etwa 3,5 cm, während der Abstand des hinteren Abschnitts 10 vom ebenen Boden 17 etwa 1,0 bis 1,5 cm ist.The distance of the free end of the upwardly bent section 12 from the flat floor 17 is approximately 3.0 to 4.0 cm, in particular approximately 3.5 cm, while the distance of the rear section 10 from the flat floor 17 is approximately 1.0 to 1 , 5 cm.

Der Radius R5 des halbkreisförmigen Endes des hinteren Abschnitts 10 beträgt etwa 5,0 cm bis 7,0 cm, insbesondere etwa 5,5 cm.The radius R5 of the semicircular end of the rear section 10 is approximately 5.0 cm to 7.0 cm, in particular approximately 5.5 cm.

Der hintere 10 und vordere Abschnitt 12 weisen in der Vertikallängsebene eine Biegesteifigkeit auf, die jeweils höchstens halb so groß ist wie die entsprechende Biegesteifigkeit des mittleren Abschnitts 11, so daß sowohl eine ausreichende Steifigkeit für das Fahren auf Schnee als auch eine ausreichend große Biegeflexibilität für das Laufen auf hartem Untergrund gewährleistet ist.The rear 10 and front section 12 have a bending stiffness in the vertical longitudinal plane, which is in each case at most half as large as the corresponding bending stiffness of the middle section 11, so that both a sufficient stiffness for driving on snow and a sufficiently large bending flexibility for the Running on hard surfaces is guaranteed.

Schließlich läßt Fig. 1 noch erkennen, daß der vordere Abschnitt 12 in Draufsicht asymmetrisch ausgebildet ist, dergestalt, daß die sich am weitesten nach vorne erstreckende Spitze bzw. "Zehe" seitlich nach innen hin verlegt ist, und zwar so weit, daß sie etwa auf Höhe der maximalen Taillierung der inneren Seite 16 des mittleren Abschnitts 11 liegt.Finally, Fig. 1 shows that the front portion 12 is asymmetrical in plan view, such that the most forwardly extending tip or "toe" is moved laterally inwards, to the extent that it is approximately at the level of the maximum waist of the inner side 16 of the middle section 11.
