Description

Die Erfindung betrifft einen Alpinski mit einem eine Lauffläche bildenden, langgestreckten Skikörper, einer auf der Oberseite des Skikörpers angeordneten Halterung zur Befestigung einer Bindung und wenigstens einem an dem Skikörper angebrachten, sich in Längsrichtung des Skikörpers erstreckenden und Druckkräfte aufnehmenden Obergurtelement, dessen Enden an dem Skikörper abgestützt sind.The invention relates to an alpine ski having an elongated ski body forming a tread, a holder arranged on the upper side of the ski body for fastening a binding and at least one upper belt element attached to the ski body and extending in the longitudinal direction of the ski body, the ends of which are attached to the ski body are supported.

Bei einem aus DE 199 17 992 bekannten Alpinski der angegebenen Art hat das in den Skikörper eingebaute Obergurtelement im mittleren Bereich des Skis die Form eines flachen, nach oben gewölbten Bogens, der sich in Längsrichtung des Skis erstreckt und ein darunter liegendes im Skikörper angeordnetes Untergurtelement überspannt. Der Bogen des Obergurtelements ist hierbei in Abhängigkeit von der von der Bindung ausgehenden Belastung in Richtung auf das Untergurtelement durchbiegbar und das Obergurtelement ist an dem Endbereich des Skis derart abgestützt, daß eine aus der Durchbiegung des Bogens resultierende Verschiebung der Enden des Obergurtelements eine Erhöhung des Traganteils der Endbereiche des Skis bewirkt.At one off DE 199 17 992 known alpine skis of the specified type has the built-in ski body Obergurtelement in the central region of the ski in the form of a flat, upwardly arched arc extending in the longitudinal direction of the ski and spans an underlying lying in the ski body lower belt element. The arc of the upper chord member is in this case depending on the outgoing of the binding load in the direction of the lower chord member and the Obergurtelement is supported on the end portion of the ski such that a resulting from the deflection of the sheet displacement of the ends of the Obergurtelements an increase of the supporting portion causes the end portions of the ski.

Der Erfindung liegt die Aufgabe zugrunde, die Laufeigenschaften eines Alpinskis der angegebenen Art weiter zu verbessern und eine sich den Belastungen des Ski anpassende Flächendruckverteilung zu ermöglichen.The invention has for its object to further improve the running characteristics of a Alpinskis of the specified type and to allow the loads of the ski adapting surface pressure distribution.

Diese Aufgabe wird durch die in Patentanspruch 1 angegebene Erfindung gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the invention specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Bei dem erfindungsgemäßen Alpinski ist die Halterung zur Befestigung der Bindung fest mit dem die Lauffläche bildenden Skikörper verbunden. Der Skifahrer kann dadurch die Bewegungen des Skis exakt steuern und kontrollieren und zuverlässig auf durch die Piste bedingte Einflüsse reagieren, wodurch ein hohes Maß an Fahrsicherheit erreicht wird. Der erfindungsgemäße Alpinski hat weiterhin den Vorteil, daß seine Biegesteifigkeit und damit die Flächendruckverteilung belastungsabhängig veränderbar ist, wodurch ein verbesserter Kantengriff und größere Steuerstabilität vor allem bei höheren Geschwindigkeiten erreicht werden können. Weiterhin zeichnet sich der erfindungsgemäße Alpinski durch eine günstige Flächendruckverteilung aus, da die Belastungen nicht nur im Bereich der Halterung für die Bindung, sondern zusätzlich auch an den Abstützstellen des Obergurtelements auf den Skikörper übertragen wird. Der Skikörper selbst kann weniger steif ausgeführt sein, wodurch eine bessere Anpassung an Pistenunebenheiten erreicht wird. Die variable Biegesteifigkeit und die Verformungsbewegung des Obergurtelements dämpfende Mittel tragen weiterhin zu einer außerordentlich hohen Laufruhe des erfindungsgemäßen Skis auch bei sehr unebenen Pistenoberflächen bei.In the alpine ski according to the invention, the holder for fixing the binding is firmly connected to the ski body forming the tread. The skier It can thus control and control the movements of the ski precisely and react reliably to influences caused by the piste, thereby achieving a high level of driving safety. The alpine ski according to the invention also has the advantage that its flexural rigidity and thus the surface pressure distribution can be changed depending on the load, as a result of which an improved edge grip and greater control stability can be achieved, above all, at higher speeds. Furthermore, the alpine ski according to the invention is characterized by a favorable surface pressure distribution, since the loads are transmitted not only in the region of the holder for the binding, but in addition to the supporting points of the Obergurtelements on the ski body. The ski body itself can be made less stiff, whereby a better adaptation to piste bumps is achieved. The variable bending stiffness and the deformation movement of the upper belt element damping means continue to contribute to an extraordinarily high smoothness of the ski according to the invention even with very uneven slope surfaces.

Ein weiterer wichtiger Vorteil des erfindungsgemäßen Alpinskis besteht darin, daß durch Veränderung der Abstützlänge sowie der Biegesteifigkeit des Obergurtelements die Laufeigenschaften des Skis in erheblichem Umfang beeinflußbar sind, so daß sich der Ski auf einfache Weise unterschiedlichen Bedürfnissen der Skifahrer anpassen läßt. Der erfindungsgemäße Alpinski eröffnet hierbei auch die Möglichkeit, durch Bereitstellen einer Anzahl von vorgefertigten Baukomponenten und durch eine ausgewählte Kombination aus diesen Baukomponenten eine den individuellen Wünschen eines Skifahrers angepaßte Skiausführung herzustellen.Another important advantage of Alpinskis invention is that by changing the support length and the bending stiffness of Obergurtelements the running characteristics of the ski are influenced to a considerable extent, so that the ski can be easily adapted to different needs of skiers. The alpine ski according to the invention also opens up the possibility here of producing a ski design adapted to the individual wishes of a skier by providing a number of prefabricated construction components and by a selected combination of these construction components.

Nach einem weiteren Vorschlag der Erfindung besteht das Obergurtelement aus wenigstens einem leichtgekrümmten Stab, der nach Art eines Bogens den Skikörper überspannt. Vorzugsweise ist das Obergurtelement aus mehreren, leicht gekrümmten Stäben gebildet, die den Skikörper überspannend nebeneinander angeordnet sind. Die Länge der Stäbe kann einheitlich oder unterschiedlich sein und größer oder kleiner sein als die halbe Länge des Skikörpers. Die Stäbe können hohl oder massiv ausgeführt sein und aus Leichtmetall oder einem Faserverbundwerkstoff hergestellt sein. Ferner können die Stäbe einen konstanten oder einen sich zu den Stabenden hin verjüngenden Querschnitt haben. Die Stäbe können außerdem einteilig oder mehrteilig ausgeführt sein. In Bezug auf den Skikörper können die Stäbe so angeordnet sein, daß die durch ihre gekrümmten Längsachsen bestimmten Ebenen entweder senkrecht zur Lauffläche des Skikörpers ausgerichtet sind oder zur Lauffläche des Skikörpers geneigt sind. Im letzteren Fall ist es vorteilhaft, wenn zwischen beiderseits der Mitte des Skikörpers angeordneten Stäben ein Zwischenraum verbleibt, in den sich die Mittelabschnitte der Stäbe unter der Wirkung von Druckkräften hineinbewegen können und die Stäbe so angeordnet sind, daß die durch ihre gekrümmten Längsachsen bestimmten Ebenen oberhalb des Skis aufeinandertreffen. Bei einer solchen Anordnung entspricht der gekrümmte Verlauf der Stäbe im wesentlichen der Taillierung des Skikörpers und ermöglicht dadurch eine vorteilhafte Gestaltung des Skis.According to a further proposal of the invention, the upper belt element consists of at least one slightly curved rod, which spans the ski body in the manner of an arc. Preferably, the upper chord member is formed of a plurality of slightly curved rods, which are arranged spanning the ski body next to each other. The length of the bars may be uniform or different and be larger or smaller than half the length of the ski body. The rods may be hollow or solid and made of light metal or a fiber composite material. Furthermore, the rods may have a constant or tapering towards the rod ends cross-section. The rods may also be made in one or more parts. With respect to the ski body, the bars may be arranged so that the planes defined by their curved longitudinal axes are either perpendicular to the tread of the ski body or inclined to the tread of the ski body. In the latter case, it is advantageous if there is a gap between bars arranged on both sides of the center of the ski body into which the middle sections of the bars can move under the action of compressive forces and the bars are arranged such that the planes defined by their curved longitudinal axes are above of the ski meet. In such an arrangement, the curved course of the bars substantially corresponds to the waist of the ski body and thereby enables an advantageous design of the ski.

Nach einem weiteren Vorschlag der Erfindung kann die Halterung zur Befestigung der Bindung in der Weise mit dem Skikörper verbunden sein, daß die elastische Verformbarkeit des Skikörpers hierdurch nicht beeinträchtigt ist. Hierzu kann vorgesehen sein, daß die Halterung wenigstens zwei in Längsrichtung in einem Abstand voneinander angeordnete Stützen aufweist, wobei eine Stütze fest und die andere Stütze längs beweglich mit dem Skikörper verbunden ist. Weist andererseits der Skikörper zwei in Längsrichtung in einem Abstand voneinander angeordnete Stützen zur Befestigung der Halterung für die Bindung auf, so ist erfindungsgemäß die Halterung an einer Stütze fest und an der anderen Stütze längsverschieblich angebracht.According to a further proposal of the invention, the holder for fixing the binding may be connected to the ski body in such a way that the elastic deformability of the ski body is not impaired thereby. For this purpose, it may be provided that the holder has at least two longitudinally spaced supports, one support fixed and the other support is longitudinally movably connected to the ski body. If, on the other hand, the ski body has two longitudinally spaced-apart supports for attaching the support for the binding, according to the invention the support is fixed to one support and longitudinally displaceable to the other support.

Nach der Erfindung weist die Halterung zur Befestigung der Bindung eine Platte auf, die sich oberhalb des Obergurtelements erstreckt. Die Platte trägt vorzugsweise an ihrer Unterseite ein Abstützelement zur Abstützung des Obergurtelements. Das Abstützelement kann erfindungsgemäß aus einer durch das Obergurtelement zusammendrückbaren Feder bestehen, die durch Ausübung einer Gegenkraft einer gegen das Abstützelement gerichteten Bewegung des Obergurtelements entgegenwirkt. In einer anderen Ausgestaltung kann das Abstützelement aus einem Lager mit einer Gleitfläche bestehen, auf der das Obergurtelement quer zu seiner Längsrichtung gleiten kann.According to the invention, the holder for fixing the binding to a plate, which is located above the Obergurtelements extends. The plate preferably carries on its underside a support element for supporting the Obergurtelements. According to the invention, the support element may consist of a spring which can be compressed by the upper belt element and counteracts this by exerting a counter force on a movement of the upper belt element directed against the support element. In another embodiment, the support member may consist of a bearing with a sliding surface on which the Obergurtelement can slide transversely to its longitudinal direction.

Um den Verformungswiderstand des erfindungsgemäßen Alpinskis und sein Verformungsverhalten auf einfache Weise einstellen zu können, ist nach einem weiteren Vorschlag der Erfindung die Abstützung wenigstens eines Endes des Obergurtelements oder der dieses bildenden Stäbe in Längsrichtung des Skikörpers verstellbar ausgeführt. Weist das Obergurtelement Stäbe auf, so kann die Längenverstellbarkeit auf einfache Weise durch eine an einem Stabende drehbar angebrachte Stellschraube bewirkt werden, die in eine Gewindebohrung eines auf den Skikörper befestigten Widerlagers eingeschraubt ist. Sind mehrteilige Stäbe vorgesehen, so können zur Erzielung der Längenverstellbarkeit einander zugekehrte Stabenden durch ein Spannschloß mit Verstellmutter miteinander verbunden sein.In order to adjust the deformation resistance of the invention Alpinskis and its deformation behavior in a simple manner, the support of at least one end of the Obergurtelements or this forming rods in the longitudinal direction of the ski body is carried out adjustable according to a further proposal of the invention. If the upper belt element has bars, then the length adjustability can be effected in a simple manner by a set screw rotatably mounted on a bar end, which is screwed into a threaded bore of an abutment fastened to the ski body. Are multi-part rods provided so may be connected to each other by a turnbuckle with adjusting nut to achieve the length adjustment mutually facing rod ends.

Zur Verringerung der Knickbeanspruchung der Stäbe können nach einem weiteren Vorschlag der Erfindung im Abstand von den an dem Skikörper befestigten Stabenden Führungen vorgesehen sein, in denen die Stäbe längsverschieblich geführt sind. Die Führungen können außerdem so gestaltet sein, daß sie eine begrenzte Querbewegung der Stäbe insbesondere in Richtung der durch ihre gekrümmten Längsachsen bestimmten Ebenen zulassen. Erfindungsgemäß können weiterhin auf die Stäbe einwirkende Dämpfungselemente vorgesehen sein, die die bei Druckbeanspruchung auftretenden Verformungsbewegungen der Stäbe dämpfen. Die Dämpfungselemente können beispielsweise in von den Stäben durchdrungenen Bohrungen der Führungen angeordnet sein und aus Buchsen oder Ringen aus elastomeren Material, beispielsweise Gummi, bestehen.To reduce the bending stress of the rods can be provided according to a further proposal of the invention at a distance from the rod end attached to the ski body guides, in which the rods are guided longitudinally displaceable. The guides may also be designed to allow limited transverse movement of the bars, particularly in the direction of the planes defined by their curved longitudinal axes. According to the invention further acting on the rods damping elements may be provided which damp the deformation movements of the rods occurring under compressive stress. The damping elements can be arranged for example in penetrated by the rods bores of the guides and off Bushings or rings of elastomeric material, such as rubber exist.

Nach einem weiteren Vorschlag der Erfindung kann auf der Oberseite des Skikörpers außerdem ein Zugelement angeordnet sein, das sich in Längsrichtung des Skikörpers erstreckt und dessen Enden an den Endbereichen des Skikörpers befestigt sind, wobei der Skikörper an wenigstens einer Stelle zwischen den Enden des Zugelements eine von dem Skikörper abstehende Stütze aufweist, auf der das gespannte Zugelement aufliegt. Das Zugelement hat die Aufgabe, die Auslenkung von gegen die Lauffläche gerichteten Biegeschwingungen der Enden des Skikörpers zu verringern, um dadurch die Laufruhe des Alpinskis zu erhöhen. Die Höhe der von dem Skikörper abstehenden Stütze kann verstellbar sein, um die Spannung des Zugelements einstellen zu können. Ebenso ist es möglich, die Befestigung eines Endes des Zugelements längenverstellbar auszuführen.According to a further proposal of the invention, a pulling element can also be arranged on the upper side of the ski body, which extends in the longitudinal direction of the ski body and whose ends are fastened to the end regions of the ski body, wherein the ski body at least one point between the ends of the tension element one of having the ski body projecting support on which the tensioned tension element rests. The tension element has the task to reduce the deflection of directed against the tread bending vibrations of the ends of the ski body, thereby increasing the smoothness of Alpinskis.

Der in den Figuren 1 und 2 dargestellte Alpinski weist einen Skikörper 1 auf, dessen Formgestalt im wesentlichen herkömmlicher Skiausführungen gleicht. Der Skikörper 1 hat an seinem vorderen Ende eine nach oben gebogene sich zur Skispitze 2 hin verjüngende Schaufel 3 und weist einen rechteckigen Querschnitt auf, dessen Höhe von den Enden des Skikörpers ausgehend zur Mitte hin zunimmt und dessen Breite von den Enden zur Mitte hin abnimmt, wodurch konkav gekrümmte Seitenflächen 4 gebildete sind. Die Unterseite des Skikörpers 1 bildet eine Lauffläche 5, deren seitliche Kanten in üblicher Weise durch metallischen Einlagen verstärkt sind. Der Skikörper 1 kann aus Holz, Kunststoff, Faserverbund-Werkstoffen und Metall sowie in Verbundbauweise aus mehreren dieser Materialien hergestellt sein.The in the Figures 1 and 2 Alpinski shown has a ski body 1, the shape of which is similar to conventional ski versions substantially. The ski body 1 has at its front end an upwardly curved blade 2 which tapers towards the ski tip 2 and has a rectangular cross section, the height of which increases from the ends of the ski body towards the middle and whose width decreases from the ends towards the middle, whereby concavely curved side surfaces 4 are formed. The underside of the ski body 1 forms a running surface 5, whose lateral edges are reinforced in the usual way by metallic inserts. The ski body 1 may be made of wood, plastic, fiber composite materials and metal as well as in composite construction of several of these materials.

Im mittleren Bereich ist auf der in Längsrichtung leicht konvex gekrümmten Oberseite 6 des Skikörpers 1 eine Halterung 7 zur Befestigung einer Bindung für den Schuh des Skifahrers angebracht. Die Halterung 7 besteht aus einer in einem Abstand von der Oberseite 6 angeordneten, ebenen Platte 8, die an ihrem vorderen und hinteren Ende jeweils zwei nach unten gerichtete Stützen 9, 10 trägt, deren freie Enden an dem Skikörper 1 befestigt sind. Die Befestigung der Stütze 9 ist so gestaltet, daß ihre Enden an dem Skikörper 1 ortsfest gehalten sind. Die Verbindung kann hierbei starr oder um eine in Querrichtung verlaufende Achse schwenkbar ausgeführt sein. Die Enden der Stützen 10 sind so an dem Skikörper 1 befestigt, daß eine begrenzte Relativbewegung zwischen den Stützen 10 und dem Skikörper 1 in Längsrichtung desselben möglich, in allen anderen Richtungen aber nicht möglich ist. Die beschriebene Befestigung der Halterung 7 an dem Skikörper 1 sorgt dafür, daß elastische Formänderungen des Skikörpers 1 unter Last durch die Halterung 7 nicht behindert werden. Der Skikörper 1 kann sich daher der jeweiligen Krümmung der Pistenoberfläche besser anpassen. Durch den Abstand der Stützen 9, 10 wird hierbei eine günstige Teilung der von der Halterung 7 ausgehenden Last auf den Skikörper 1 erreicht.In the central region, a holder 7 for attaching a binding for the skier's shoe is mounted on the upper side 6 of the ski body 1, which is slightly convexly curved in the longitudinal direction. The holder 7 consists of a arranged at a distance from the top 6, flat plate 8, which carries at its front and rear ends in each case two downwardly directed supports 9, 10, whose free ends are fixed to the ski body 1. The attachment of the support 9 is designed so that their ends are held stationary on the ski body 1. The connection can in this case be designed to be rigid or pivotable about a transverse axis. The ends of the supports 10 are fixed to the ski body 1, that a limited relative movement between the supports 10 and the ski body 1 in the longitudinal direction of the same possible, but in all other directions is not possible. The described attachment of the holder 7 to the ski body 1 ensures that elastic deformations of the ski body 1 under load are not hindered by the holder 7. The ski body 1 can therefore better adapt to the respective curvature of the runway surface. Due to the distance of the supports 9, 10 a favorable division of the outgoing from the holder 7 load is achieved on the ski body 1 in this case.

Auf der Oberseite 6 des Skikörpers 1 befindet sich unterhalb der Platte 8 und zwischen den Stützen 9, 10 ein Obergurtelement 11, das aus zwei parallelen, zur Aufnahme von Druckkräften geeigneten Stäben 12 besteht. Die Stäbe 12 haben eine nach oben gewölbte Krümmung und sind symmetrisch zur Mittelebene des Skikörpers 1 angeordnet. Ihre gekrümmten Mittelachsen liegen in zur Lauffläche 5 im wesentlichen senkrechten Ebenen. Die Stäbe 12 bestehen aus Rohren aus Leichtmetall und haben einen konstanten kreisförmigen Querschnitt. Die Enden der Stäbe 12 sind an Widerlagern 13, 14 abgestützt, die in einem Abstand von den Enden des Skikörpers 1 auf dessen Oberseite 6 befestigt sind. Die Widerlager 13, 14 bestehen aus flachen Blöcken, die an einer Seite Bohrungen haben, in die die Stäbe 12 eingesteckt sind. Zwischen den Widerlagern 13, 14 und den Stützen 9, 10 sind außerdem auf dem Skikörper 1 Führungselemente 15 befestigt. Die Führungselemente 15 haben jeweils zwei parallele Bohrungen, durch die die Stäbe 12 hindurchgesteckt sind. Der Durchmesser dieser Bohrungen ist größer als der Außendurchmesser der Stäbe 12, so daß die Stäbe 12 begrenzte Querbewegungen innerhalb der Bohrungen ausführen können. Die Führungselemente 15 dienen dazu, das Biegeknicken der Stäbe 12 bei Belastung des Skis zu begrenzen und ein seitliches Ausknicken der Stäbe 12 zu verhindern. In die Bohrungen der Führungselemente 15 eingesetzten Buchsen oder Ringe aus elastomerem Material können außerdem zur Dämpfung von Schwingungen beitragen.On the upper side 6 of the ski body 1 is below the plate 8 and between the supports 9, 10 a Obergurtelement 11, which consists of two parallel, suitable for receiving pressure forces rods 12. The rods 12 have an upwardly curved curvature and are arranged symmetrically to the median plane of the ski body 1. Their curved central axes lie in the tread 5 substantially vertical planes. The rods 12 are made of light metal tubes and have a constant circular cross-section. The ends of the rods 12 are supported on abutments 13, 14, which are fastened at a distance from the ends of the ski body 1 on its upper side 6. The abutments 13, 14 consist of flat blocks, which have holes on one side, in which the rods 12 are inserted. Between the abutments 13, 14 and the supports 9, 10 guide elements 15 are also mounted on the ski body. The guide elements 15 each have two parallel holes through which the rods 12 are inserted. The diameter of these holes is larger than the outer diameter of the rods 12, so that the rods 12 can perform limited transverse movements within the holes. The guide elements 15 serve to limit the bending buckling of the rods 12 under load of the ski and to prevent lateral buckling of the rods 12. Bushings or rings of elastomeric material used in the bores of the guide elements 15 can also contribute to the damping of vibrations.

Der Scheitelbereich 16 der gekrümmten Stäbe 12 befindet sich unter der Platte 8 in einem Abstand von dieser, so daß er unter der Einwirkung von an den Widerlagern 13, 14 auf die Stäbe 12 einwirkenden Druckkräften durch Biegeknicken der Stäbe 12 nach oben ausweichen kann. Dem Ausweichen des Scheitelbereichs 16 wirkt ein Abstützelement 17 entgegen, das an der Unterseite der Platte 8 angebracht ist. Das Abstützelement 17 besteht aus einem elastisch zusammendrückbaren Material, zum Beispiel Gummi oder Schaumgummi, und übt mit zunehmender Verformung durch die Stäbe 12 eine im vorbestimmten Maße wachsende Gegenkraft aus, die das Ausweichen der Scheitelbereiche 16 der Stäbe 12 zunehmend hemmt und schließlich auf einen Maximalwert begrenzt. Bei diesem Vorgang, der durch eine stärkere Belastung der Endbereiche des Alpinskis hervorgerufen wird, nimmt die Biegesteifigkeit des Alpinskis und damit der relative Traganteil seiner Endbereiche zu. Dies führt zu einer besseren Steuerbarkeit des Ski und infolge geringerer Verformungswege zu größerer Laufruhe. Das Verformungsverhalten des Alpinski kann zudem durch Änderung des Verformungswiderstands des Abstützelements 17 variiert und an die Bedürfnisse des Skifahrers angepaßt werden. Zum Variieren des Verformungswiderstands des Abstützelements 17 kann dieses gegen ein weicheres oder härteres ausgetauscht werden. Weitere Variationsmöglichkeiten bestehen in der Änderung der Länge der Stäbe 12 sowie ihrer anfänglichen Krümmung.The apex portion 16 of the curved bars 12 is located below the plate 8 at a distance therefrom, so that it can deflect upwardly under the action of compressive forces acting on the abutments 13, 14 on the bars 12 by bending the bars 12. The deflection of the apex portion 16 counteracts a support member 17 which on the underside of the plate. 8 is appropriate. The support member 17 is made of an elastically compressible material, for example rubber or foam rubber, and with increasing deformation by the rods 12 exerts a predetermined amount of increasing counterforce, which increasingly inhibits the deflection of the apex portions 16 of the rods 12 and finally limited to a maximum value , In this process, which is caused by a greater load on the end regions of alpine skis, the flexural rigidity of the alpine skis and thus the relative load-bearing ratio of its end regions increases. This leads to a better controllability of the ski and due to lower deformation paths to smoother running. The deformation behavior of the alpine ski can also be varied by changing the deformation resistance of the support element 17 and adapted to the needs of the skier. To vary the deformation resistance of the support element 17, this can be replaced by a softer or harder. Other variations are the change in the length of the bars 12 and their initial curvature.

Zur Begrenzung der Verformung des Alpinskis bei Entlastung ist auf der Oberseite 6 zwischen den Stäben 12 ein Zugelement 18 in Form eines zugfesten Gewebebandes vorgesehen. Das Zugelement 18 liegt auf den Führungselementen 15 auf und ist durch diese in einem Abstand von der Oberseite 6 des Skikörpers 1 gehalten. Die Enden des Zugelements 18 sind an den Widerlagern 13, 14 befestigt. Bei unbelastetem Alpinski ist das Zugelement 18 leicht gespannt. Wird der Alpinski belastet, so verliert das Zugelement seine Spannung, kann aber bei Bedarf durch ein an der Platte 8 abgestütztes, nachgiebiges Spannelement nach Art eines Riemenspanners leicht unter Vorspannung gehalten werden.In order to limit the deformation of the alpine skis during relief, a tension element 18 in the form of a tension-resistant fabric band is provided on the upper side 6 between the bars 12. The tension element 18 rests on the guide elements 15 and is held by them at a distance from the upper side 6 of the ski body 1. The ends of the tension element 18 are attached to the abutments 13, 14. When the alpine ski is unloaded, the tension element 18 is slightly tensioned. If the alpine ski is loaded, the tension element loses its tension, but can easily be held under pretension by a resilient expansion element, supported on the plate 8, in the manner of a belt tensioner.

Das Zugelement 18 hat beim Skifahren folgende Wirkung. Wird die Skispitze beim Einfahren in eine Mulde entlastet, so verringert das sich dann spannende Zugelement 18 die Entlastungsbewegung der Skispitze. Durch die Abstützung des Zugelements 18 an dem Widerlager 14 erhöht sich hierbei die dort auf das hintere Ende des Skikörpers einwirkende Zugkraft, wodurch eine leichte Anhebung des Skiendes bewirkt wird. Gelangt der Alpinski mit dem hinteren Ende in eine Mulde, so kehrt sich die Wirkung an Skispitze und Skiende um. Insgesamt wird durch dieses Verhalten des Alpinskis eine spürbare Verringerung von Vertikalschwingungen seiner Enden und ein ruhigerer, vor allem bei unebener Skipiste richtungsstabilerer Lauf erreicht. Die Reibung des Zugelements 18 an den Führungselementen 15 hat zudem einen schwingungsdämpfenden Effekt.The tension element 18 has the following effect while skiing. If the tip of the ski is relieved when entering a trough, then the tensioning element 18, which is then tensioned, reduces the unloading movement of the ski tip. By the support of the tension element 18 on the abutment 14 in this case increases the there on the rear End of the ski body acting tensile force, causing a slight increase in the ski end is effected. If the alpine ski gets into a hollow with the rear end, the effect is reversed at the ski tip and at the ski end. Overall, this behavior of the alpine skis achieves a noticeable reduction of vertical vibrations of its ends and a calmer, more directionally stable run, especially on uneven slopes. The friction of the tension element 18 on the guide elements 15 also has a vibration-damping effect.

Das in den Figuren 3 bis 5 dargestellte Ausführungsbeispiel unterscheidet sich von dem vorherigen in den nachfolgend beschriebenen Merkmalen. Es sind die das Obergurtelement 11 bildenden, gekrümmten Stäbe 12 so an den Widerlagern 13, 14 befestigt, daß die Ebenen, in denen die gekrümmten Mittelachsen der Stäbe 12 liegen, etwa in einem Winkel von 45° zur Lauffläche 5 des Skikörpers 1 verlaufen, und zwar derart, daß die Ebenen oberhalb des Skikörpers 1 zusammentreffen. Diese Anordnung der Stäbe 12 hat den Vorteil, daß ihre benachbarten Enden einen größeren Abstand voneinander haben können, so daß die von den Stäben aufzunehmenden Druckkräfte näher an den Kanten des Skikörpers 1 wirksam sind und dadurch stärker zur Verringerung der Torsionsbeanspruchung des Skis beitragen.That in the FIGS. 3 to 5 illustrated embodiment differs from the previous in the features described below. There are the Obergurtelement 11 forming, curved rods 12 attached to the abutments 13, 14, that the planes in which the curved center axes of the rods 12 lie, approximately at an angle of 45 ° to the tread 5 of the ski body 1 run, and Although such that the levels meet above the ski body 1. This arrangement of the bars 12 has the advantage that their adjacent ends can be spaced a greater distance apart so that the compressive forces to be absorbed by the bars are closer to the edges of the ski body 1 and thereby contribute more to reducing the torsional stress on the ski.

Bedingt durch die geneigte Lage der Ebenen ihrer gekrümmten Mittelachsen sind die Stäbe 12 bei diesem Ausführungsbeispiel bestrebt, mit ihren Scheitelbereichen 16 eine Ausweichbewegung in Richtung der in Figur 5 gezeigten Pfeile auszuführen. Diese Ausweichbewegung wird hierbei zur Skimitte hin umgelenkt. Hierzu ist an der Unterseite der Platte 8 der Halterung 7 ein Lagerelement 20 mit einer ebenen Gleitfläche vorgesehen, an der die Scheitelbereiche 16 der Stäbe 12 anliegen. Werden die Stäbe 12 durch Druckkräfte belastet, so sind ihre Scheitelbereiche 16 durch das Lagerelement 20 daran gehindert, sich in Richtung der Pfeile zu bewegen, sondern sind gezwungen, in Richtung der Skimitte an dem Lagerelement 20 entlang zu gleiten. Zwischen den beiden Scheitelbereichen 16 ist ein federndes Abstützelement 21 angeordnet, das an dem Skikörper 1 befestigt ist und eine der Ausgleichbewegung der Scheitelbereiche 16 entgegenwirkende Federkraft erzeugt. Durch Veränderung der anfänglichen Federkraft und der Federkennlinie des Abstützelements 21 können die Biegesteifigkeit des Skis und seine Laufeigenschaften verändert werden.Due to the inclined position of the planes of their curved center axes, the rods 12 are endeavored in this embodiment, with their apex areas 16 an evasive movement in the direction of in FIG. 5 execute arrows shown. This evasive movement is thereby deflected towards the center of the ski. For this purpose, a bearing element 20 is provided with a flat sliding surface on the underside of the plate 8 of the holder 7, against which the apex portions 16 of the rods 12. If the bars 12 are loaded by compressive forces, their vertex areas 16 are prevented by the bearing element 20 from moving in the direction of the arrows, but are forced to slide along the bearing element 20 in the direction of the ski center. Between the two vertex areas 16 a resilient support member 21 is arranged, which is fixed to the ski body 1 and generates a compensating movement of the apex portions 16 counteracting spring force. By changing the initial spring force and the spring characteristic of the support element 21, the flexural rigidity of the ski and its running properties can be changed.

Bei dem Ausführungsbeispiel gemäß den Figuren 3 bis 5 haben die Stäbe 12 zusätzlich die Funktion, das Biegeverhalten des Skis bei Entlastung zu beeinflussen. Hierzu sind die Stäbe 12 so in den Widerlagern 13, 14 befestigt, daß auch Zugkräfte übertragen werden können. Weiterhin sind zwischen den Stäben 12 und den Stützen 9, 10 der Halterung 7 nachgiebige Abstützelemente 22 vorgesehen, an denen die Stäbe 12 anliegen. Wird der Skikörper 1 beim Fahren an einem Ende plötzlich entlastet, so erzeugt die dadurch eingeleitete Bewegung des Skiendes in Richtung der Lauffläche an den Enden der Stäbe 12 eine Zugkraft. Unter der Wirkung dieser Zugkraft sind die Stäbe 12 bestrebt, ihre Krümmung durch Ausweichen in Richtung der Stützen 9, 10 zu verringern, wobei sie die nachgiebigen Abstützelemente 22 je nach Höhe der Zugkraft mehr oder weniger stark zusammendrücken. Durch Veränderung der Nachgiebigkeit der Abstützelemente 22 kann dieser Ausgleichsvorgang und damit das Biege- und Schwingungsverhalten des Skis ebenfalls beeinflußt werden.In the embodiment according to the FIGS. 3 to 5 In addition, the bars 12 have the function of influencing the bending behavior of the ski when it is being relieved. For this purpose, the rods 12 are fixed in the abutments 13, 14, that tensile forces can be transmitted. Furthermore, resilient support elements 22 are provided between the bars 12 and the supports 9, 10 of the holder 7, against which the bars 12 abut. If the ski body 1 is suddenly relieved when driving at one end, the movement of the ski in the direction of the running surface initiated at the ends of the bars 12 produces a tensile force. Under the effect of this tensile force, the rods 12 tend to reduce their curvature by dodging in the direction of the supports 9, 10, more or less compressing the resilient support members 22 depending on the level of traction. By changing the flexibility of the support elements 22, this compensation process and thus the bending and vibration behavior of the ski can also be influenced.

Neben den beschriebenen Ausführungsbeispielen sind zahlreiche weitere Ausführungsformen des erfindungsgemäßen Alpinskis möglich. So kann beispielsweise die Zahl der das Obergurtelement bildenden Stäbe größer sein, wobei sowohl eine gerade als auch eine ungerade Stabanzahl in Frage in kommt. Neben der beschriebenen symmetrischen Anordnung der Stäbe kann zur Erzielung besonderer Laufeigenschaften auch eine unsymmetrische Anordnung vorgesehen sein, in dem beispielsweise Stäbe unterschiedlicher Länge oder unterschiedlicher Steifigkeit nebeneinander auf einem Skikörper angeordnet sind Auch die Nachgiebigkeit der mit den Stäben zusammenwirkenden Abstützelemente kann bei jedem Stab anders sein, um ein unsymmetrisches Verformungsverhalten des Alpinskis zu erreichen. Der erfindungsgemäße Alpinski bietet weiterhin die Möglichkeit, die das Biegeverhalten beeinflussenden Komponenten leicht auswechselbar oder hinsichtlich ihrer Wirkungsparameter verstellbar zu gestalten, um dem Skifahrer die Möglichkeit zu geben, vor Ort die Laufeigenschaften des Skis den jeweiligen Pistenverhältnissen anzupassen. Weiterhin kann der efindungsgemäße Ski nach Art eines Baukastensystems hergestellt werden, wobei die von einem Käufer gewünschten Eigenschaften durch Zusammenbau des Skis aus den hierfür geeigneten Einzelteilen in individuellem Zuschnitt verwirklicht werden kann.In addition to the described embodiments, numerous other embodiments of the alpine ski according to the invention are possible. For example, the number of rods forming the upper chord member may be greater, with both a straight and an odd number of rods in question. In addition to the described symmetrical arrangement of the rods may be provided to achieve special running characteristics and an asymmetrical arrangement in which, for example, rods of different lengths or different stiffness are arranged side by side on a ski body and the flexibility of the cooperating with the rods Support elements may be different for each rod to achieve an asymmetrical deformation behavior of alpine skis. The alpine ski according to the invention furthermore offers the possibility of making the components which influence the bending behavior easily replaceable or adjustable in terms of their effect parameters in order to give the skier the possibility of adapting the running properties of the ski to the respective slope conditions on site. Furthermore, the ski according to the invention can be produced in the manner of a modular system, wherein the properties desired by a buyer can be realized by assembling the ski from the individual parts suitable for this purpose in individual cutting.
