Abstract

In order to improve the running characteristics of a ski (1) with a spring board (2) which does not break out in the rear region in the case of short curves and when travelling diagonally on steep slopes during downhill skiing, the mass forces occurring of the skier, which are transmitted approximately in the vertical continuation from the lower leg to the ski boot, are supported resiliently in relation to the ski (1) at least at one point between the articulated connection of the front and rear ends of the spring board (2). In order to improve rigidity against twisting and lateral stability of the spring board (2) in relation to the ski (1), the spring board (2) is connected by its front and rear ends to the surface of the ski in an articulated manner so that the spring board (2) describes a vertical movement and in the longitudinal axis of the ski a horizontal movement relative to the surface of the ski. <IMAGE>

Description

Federbrett für einen Ski.Spring board for a ski.

Die Erfindung betrifft ein Federbrett, daß sich im mittleren Bereich eines Skis auf dessen Oberseite befindet.The invention relates to a spring board that is located in the central region of a ski on its top.

Das Federbrett gemäß DE-PS 26 01 951.2 soll bei Belastung durch den Skiläufer, infolge des Abstandes zwischen dem Befestigungspunkt mit dem Ski und dem Vorderbacken der Skibindung ein Drehmoment erzeugen, daß den Ski vor dem Befestigungspunkt mit dem Federbrett entlastet, wodurch die Ausführungen von Richtungsänderungen beim Alpinskilauf erleichtert werden sollen. Das Federbrettende ist gegenüber dem Ski federnd abgestützt. Bei diesem Ski mit einem auf dessen Oberseite befindlichen Federbrett wird als nachteilig angesehen, daß die Massenkräfte des Skiläufers an den Befestigungspunkten des vorderen und hinteren Ende des Federbrettes mit dem Ski, auf diesen übertragen werden.The spring board according to DE-PS 26 0 1 951.2 should generate a torque when loaded by the skier, due to the distance between the attachment point with the ski and the toe of the ski binding, that relieves the ski before the attachment point with the spring board, thereby making the statements by Changes in direction during alpine skiing should be facilitated. The end of the spring board is resiliently supported in relation to the ski. In this ski with a spring board located on its upper side, it is considered disadvantageous that the mass forces of the skier are transmitted to the ski at the fastening points of the front and rear ends of the spring board.

Bei dieser Art der Kraftübertragung von Massenkräften durch den Skiläufer, vom Federbrett auf den Ski neigt dieser dazu, daß er bei der Ausführung von Richtungsänderungen, speziell bei kurzgezogenen Schwüngen im Alpinskilauf im hinteren Bereich ausbricht. Auch bei Schrägfahrten an steileren Hängen wirkt sich die Art der Kraftübertragung von Massenkräften am vorderen und hinteren Ende des Federbrettes auf den Ski ungünstig auf die Führungseigenschaften und Spurtreue aus. Der Ski neigt auch in diesem Fall dazu im hinteren Bereich auszubrechen.With this type of force transmission of mass forces by the skier, from the springboard to the ski, the latter tends to break out in the rear area when carrying out changes in direction, especially in the case of short turns in alpine skiing. Also at Sloping slopes on steeper slopes, the type of force transmission of mass forces at the front and rear end of the spring board on the ski has an unfavorable effect on the guiding properties and directional stability. In this case, too, the ski tends to break out in the rear area.

Weiterhin ist gemäß DE-OS 26 34 748 ein Ski mit Federbrett bekannt, wo der federbewirkende Schenkel des Federbrettes zwischen dem Vorderbacken der Skibindung und dem feststehenden mit dem Ski verbundenen, halbringförmig zur Aufnahme eines elastischen Zylinders ausgebildet ist. Das Federbrettende ist über eine ringförmige Blattfeder gelenkig mit der Skioberfläche verbunden. Auch bei diesem Ski mit Federbrett ist nachteilig, daß die Massenkräfte des Skiläufers an den Befestigungspunkten des vorderen und hinteren Ende des Federbrettes mit dem Ski, auf diesen übertragen werden. Auch dieser Ski neigt dazu, daß er bei Ausführungen von kurzgezogenen Schwüngen und bei Schrägfahrten an steileren Hängen im hinteren Bereich ausbricht, wodurch die Führungseigenschaften und Spurtreue des Ski ungünstig beeinflußt werden. Als weiterer Nachteil wird angesehen, daß der Ski durch die alleinige Abstützung des Federbrettes mit dem halbringförmig ausgebildeten federbewirkenden Schenkel und der ringförmigen Blattfeder, ohne mechanische Führung, beim Kanteneinsatz zu wenig Verwindungssteifigkeit und Seitenstabilität aufweist, wodurch besonders in steileren Häng3n eine übermäßige Hangtrift auftritt.Furthermore, according to DE-OS 26 34 748, a ski with a spring board is known, where the spring-acting leg of the spring board is formed between the front jaw of the ski binding and the fixed ski-connected, semi-ring-shaped for receiving an elastic cylinder. The end of the spring board is connected to the ski surface in an articulated manner via an annular leaf spring. It is also disadvantageous in this ski with a spring board that the mass forces of the skier are transmitted to the ski at the fastening points of the front and rear ends of the spring board with the ski. This ski also tends to break out in the rear area when performing short turns and on inclined slopes on steep slopes, as a result of which the ski's guiding properties and directional stability are adversely affected. A further disadvantage is considered that the ski by the sole support of the spring board with the semi-ring-shaped spring causing leg and the annular leaf spring without mechanical guide having at edge insert too little torsional stiffness and lateral stability, whereby n particularly in steeper Häng 3 excessive slope drift occurs .

Die durch den Anmeldungsgegenstand zu lösende Aufgabe wird darin gesehen,den am nächststehend bekannten Ski mit Federbrett der DE-OS 26 34 748 in der Weise auszubilden, daß die Führungseigenschaften und Spurtreue auch bei kurzgezogenen.Schwüngen und die Abtrift bei Schrägfahrten in steileren Hängen verbessert sind.The problem to be solved by the subject of the application is seen in the closest known ski to train with springboard of DE-OS 26 34 748 in such a way that the guiding properties and directional stability are improved even in the case of short-drawn turns and the drift when driving on inclines on steeper slopes.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das vordere und hintere Ende des Federbrettes durch H-förmige Gelenkarme, die in auf der Skioberfläche angeordneten Lagerelementen geführt werden, mit dem Ski so verbunden ist, daß durch das Drehen der Gelenkarme um ihre Gelenkachsen, das Federbrett eine vertikale und horizontale Bewegung zur Skioberfläche beschreibt und das Federbrett mindestens an einer Stelle zwischen den gelenkigen Anbindungen des vorderen und hinteren Ende, federnd gegenüber dem.S.ki abgestützt ist.The object is achieved in that the front and rear ends of the spring board are connected to the ski by H-shaped articulated arms, which are guided in bearing elements arranged on the ski surface, in such a way that by rotating the articulated arms about their articulated axes, the spring board describes a vertical and horizontal movement to the ski surface and the spring board is supported at least at one point between the articulated connections of the front and rear ends, resiliently against the S. ski.

Eine andere Lösung dieser Aufgabe ist erfindungsgemäß durch die Merkmale im kennzeichnenden Teil des Anspruches 2 angegeben. Bei dieser Ausbildung wird das vordere Ende des Federbrettes schwenkbar mit hochgesetztemSchwenkpunkt und das hintere Ende über ein H-förmig ausgebildetes Doppelgelenk, bestehend aus einem H-förmig gestreckten und H-förmig gekröpften Gelenkarm und einem auf der Skioberfläche angeordneten Lagerelement mit dem Ski verbunden und das Federbrett mindestens an einer Stelle zwischen den gelenkigen Anbindungen des vorderen und hinteren Ende, federnd gegenüber dem Ski abgestützt.Another solution to this problem is according to the invention specified by the features in the characterizing part of claim 2. In this embodiment, the front end of the spring board is pivotally connected to the ski with the pivot point raised and the rear end is connected to the ski via an H-shaped double joint, consisting of an H-shaped elongated and H-shaped cranked articulated arm and a bearing element arranged on the ski surface Spring board at least at one point between the articulated connections of the front and rear ends, resiliently supported against the ski.

Die,mit dieser Erfindung erzielbaren Vorteile bestehen darin, daß die Massenkräfte des Skiläufers, die in der normalen Gleichgewichtslage im Alpinskilauf etwa in der senkrechten Fortsetzung des Unterschenkels über den Skischuh auf den Ski erfolgt, vorzugsweise punktförmig, mindestens an einer Stelle federnd im Bereich der Skischuhsohle vom Federbrett auf den Ski übertragen werden, wodurch der Ski bei der Ausführung von kurzgezogenen Schwüngen und bei Schrägfahrten in steileren Hängen im hinteren Bereich nicht mehr ausbricht und die Führungseigenschaften und Spurtreue verbessert sind. Durch die gelenkförmige Anbindung des vorderen und hinteren Ende des Federbrettes mit dem Ski, sind auch die Verwindungssteifigkeit und Seitenstabilität desselben verbessert. Die gelenkförmige Anbindung hat den Vorteil, daß am vorderen und hinteren Ende des Federbrettes keine vertikalen Kräfte auf -den Ski übertragen werden. Dadurch wird auch die Biegelinie des Ski nicht beeinflußt. Die horizontale Bewegung des Federbrettes gegenüber dem Ski wirkt sich bei einer beschleunigten bzw. verzögerten Bewegung des Skiläufers, bedingt durch unterschiedliche Geländeformationen oder der unterschiedlichen Reibung zwischen Skilauffläche und Schnee oder aber durch Richtungsänderungen die vom Skiläufer eingeleitet werden, dämpfend auf die Massenkräfte des Skiläufers in Skilängsachse aus.The advantages that can be achieved with this invention are that the mass forces of the skier, which in the normal equilibrium position in alpine skiing, for example in the vertical continuation of the lower leg via the ski boot onto the ski, preferably in a punctiform manner, at least at one point in the area of the ski boot sole, is transferred springily from the spring board to the ski, as a result of which the ski performs short turns and during Inclined driving on steep slopes in the rear area no longer breaks out and the guiding properties and directional stability are improved. Due to the articulated connection of the front and rear end of the spring board with the ski, the torsional rigidity and lateral stability of the ski are also improved. The articulated connection has the advantage that no vertical forces are transmitted to the ski at the front and rear ends of the spring board. This also does not affect the ski's bending line. The horizontal movement of the spring board in relation to the ski has a dampening effect on the mass forces of the skier in the longitudinal axis when the skier accelerates or decelerates, due to different terrain formations or the different friction between the skiing surface and snow or due to changes in direction initiated by the skier out.

In der Zeichnung Fig. 1, 2 und 3 ist das vordere und hintere Ende des Federbrettes 2 mit gleichlang H-förmig ausgebildeten Gelenkarmen 5 und 6 über die Lagerelemente 7 und 8 mit der Skioberfläche so verbunden, daß bei Belastung, das Federbrett 2 durch das Drehen der Gelenkarme 5 und 6 um ihre Gelenkachsen eine parallele, vertikale und eine in Richtung Skißpitze horizontale Bewegung zur Skioberfläche erfolgt. Die Gelenkarme 5 und 6 können aber auch so angeordnet sein, daß durch das Drehen um ihre Gelenkachsen eine parallele, vertikale und eine in Richtung Skiende horizontale Bewegung des Federbrettes 2 zur Skioberfläche bewirkt wird. Bei Ausbildung unterschiedlicher Längen der Gelenkarme 5 und 6 wird eine nichtparallele Anordnung bzw.'Bewegung bei Belastung des Federbrettes 2 gegenüber dem Ski 1 erreicht.In the drawing Fig. 1, 2 and 3, the front and rear ends of the spring board 2 with the same length H-shaped articulated arms 5 and 6 are connected via the bearing elements 7 and 8 to the ski surface so that when loaded, the spring board 2 by the Rotating the articulated arms 5 and 6 about their articulated axes results in a parallel, vertical and horizontal movement in the direction of the ski tip towards the ski surface. The articulated arms 5 and 6 can also be arranged such that a parallel, vertical and horizontal movement of the spring board 2 to the ski surface is effected by rotating about their articulation axes. When different lengths of the articulated arms 5 and 6 are formed, a non-parallel arrangement or movement when the spring board 2 is loaded relative to the S ki 1 is achieved.

Das vordere Ende des Federbrettes 2, ist beidseitig um die Länge des H-förmigen Gelenkarmes 5 und um die Breite der Gelenkschenkel 1o zur Aufnahme derselben ausgespart. Um den maximalen Federweg zwischen Federbrettunterseite und Skioberfläche zu erreichen, ist der Verbindungssteg der Gelenkarme 1o um die Dicke des Federbrettes 2 zur Skioberflächenseite hin versetzt. Das Lagerelement 8 für das hintere Federbrettende weist als Anschlag für den Verbindungssteg der beiden Gelenkschenkel 11 des Gelenkarmes 6 eine Verlängerung auf, um den Federweg des Federbrettes 2 nach oben zu begrenzen. Das Federbrett 2 ist gegenüber den Ski 1 durch eine Kegelfeder 3 punktförmig im Bereich der Skischuhsohle abgestützt. Die Kegelfeder 3 ist an der Federbrettunterseite befestigt und auf der Skioberfläche in einem Teller 4 gleitend angeordnet, um die horizontalen Bewegungen des Federbrettes 2 bei der Belastung durch den Skiläufer mitzumachen. Durch die Reibung des Tellers 4 auf der Skioberfläche werden gleichzeitig die Schwingungen des Federbrettes 2 gedämpft. Die Kegelfelder 3 kann aber auch auf der Skioberfläche befestigt und auf der Federbrettunterseite gleitend angeordnet sein. Bei asymetrischer Ausbildung der Kegelfeder 3, kann diese auch auf der Skioberfläche und an der Federbrettunterseite fest fixiert angeordnet sein. Damit der maximale Federweg des Federbrettes 2 erreicht wird, ist zur Aufnahme der zusammengepreßten Kegelfeder 3 im maximalen Belastungszustand, in der Federbrettunterseite eine Aussparung 9 vorgesehen.The front end of the spring board 2 is recessed on both sides by the length of the H-shaped articulated arm 5 and by the width of the articulated legs 1o for receiving the same. In order to achieve the maximum spring travel between the underside of the spring board and the ski surface, the connecting web of the articulated arms 10 is offset by the thickness of the spring board 2 towards the ski surface side. The bearing element 8 for the rear end of the spring board has an extension as a stop for the connecting web of the two joint legs 11 of the articulated arm 6 in order to limit the spring travel of the spring board 2 upwards. Compared to the ski 1, the spring board 2 is supported point by point in the area of the ski boot sole by a conical spring 3. The conical spring 3 is fastened to the underside of the spring board and slidably arranged on the ski surface in a plate 4 in order to take part in the horizontal movements of the spring board 2 when the skier loads. The vibrations of the spring board 2 are damped by the friction of the plate 4 on the ski surface. The cone fields 3 can, however, also be fastened to the ski surface and arranged to slide on the underside of the spring board. If the conical spring 3 is asymmetrical, it can also be arranged in a fixed manner on the ski surface and on the underside of the spring board. In order that the maximum spring travel of the spring board 2 is reached, a recess 9 is provided in the underside of the spring board for receiving the compressed conical spring 3 in the maximum load state.

Als federnde Abstützung des Federbrettes 2 gegenüber dem Ski 1 können auch eine oder mehrere übereinanderliegende sichelförmig ausgebildete Blattfedern, die zeichnerisch nicht dargestellt sind, angeordnet sein. Die beiden Enden der Blattfeder, sind jeweils als ein Loslager und ein Festlager ausgebildet, die wahlweise auf der Skioberfläche oder auf der Federbrettunterseite angeordnet sein können. Entsprechend dazu stützt sich der Rundbogen der Blattfeder als Loslager entweder gegen die Skioberfläche oder die Federbrettunterseite ab.As a resilient support of the spring board 2 opposite the ski 1 can also be arranged one or more superimposed sickle-shaped leaf springs, which are not shown in the drawing. The two ends of the leaf spring are each designed as a floating bearing and a fixed bearing, which can be arranged either on the ski surface or on the underside of the spring board. Accordingly, the arch of the leaf spring is supported as a floating bearing either against the ski surface or the underside of the spring board.

Weiterhin kann als federnde Abstützung des Federbrettes 2 gegenüber dem Ski 1 ein elastischer Werkstoff, der ebenfalls zeichnerisch nicht dargestellt ist,mit unterschiedlich großer Auflagerfläche auf der Skioberfläche oder Federbrettunterseite, angeordnet sein.Furthermore, as a resilient support of the spring board 2 with respect to the ski 1, an elastic material, which is also not shown in the drawing, with a differently large bearing surface on the ski surface or underside of the spring board can be arranged.

Die federnde Abstützung des-Federbrettes 2 gegenüber dem Ski 1 kann sowohl punktförmig als auch flächenartig ausgebildet sein.The resilient support of the spring board 2 with respect to the ski 1 can be designed both point-like and area-like.

Bei der in Fig. 4 - 7 gezeigten Ausbildung, erfolgt die Abstützung des schwenkbaren Federbrettes 12 mit hochgesetztem Schwenkpunkt, der bei etwa fünfzig Prozent des Federweges am Federbrettende liegt, gegenüber dem Ski 1 durch zwei Drehstabfedern 13, die innerhalb des schwenkbaren Federbrettes 12 mit hochgesetztem Schwenkpunkt beiderseits in Skilängsachse angeordnet sind, am vorderen Ende desselben eingespannt und beim Austritt an der Unterseite des schwenkbaren Federbrettes 12 mit hochgesetztem Schwenkpunkt in Führungen 14 verlaufen. Die Drehstabfedern 13 können aber auch am hinteren Ende oder bei Anordnung von mehr als zwei Drehstabfedern 13 am hinteren und vorderen Ende des schwenkbaren Federbrettes 12 mit hochgesetztem Schwenkpunkt eingespannt sein. In Skilängsachse sind die Drehstabfedern 13-um 9o Grad und zur Skiquerachse nach der jeweils anderen Seite des Ski 1 abgewinkelt, wodurch sich die entstehenden Schenkel kreuzen und sich die Schenkelenden auf der Skioberfläche, in dessen Bereich ein Belag mit geringer Reibung angeordnet ist, je nach Belastung durch den Skiläufer quer zur Skilängsachse nach außen oder innen bewegen. Das vordere Ende des schwenkbaren Federbrettes 12 mit hochgesetztem Schwenkpunkt ist über ein Schwenklager 15 das quer zur Skilängsachse angeordnet ist mit dem Ski 1 verbunden. Am hinteren Ende ist ein H-förmig ausgebildetes Doppelgelenk angeordnet, bestehend aus einem gestreckten H-förmigen Gelenkarm 16 und einem gekröpften Gelenkarm 17 die jeweils mit ihren einen Ende über eine quer zur Skilängsachse durchsteckbare Achse 18 miteinander gelenkig verbunden sind und mit ihren anderen freien Enden zum einen gelenkig mit dem Ende des schwenkbaren Federbrettes 12 mit hochgesetztem Schwenkpunkt und zum anderen gelenkig mit dem auf der Skioberfläche angeordnetem Lagerelement 19 verbunden ist.In the embodiment shown in FIGS. 4-7, the pivotable spring board 12 is supported with the pivot point raised, which is approximately fifty percent of the spring travel at the end of the spring board, with respect to the ski 1 by means of two torsion bar springs 13, which are set up within the pivotable spring board 12 The pivot point is arranged on both sides in the longitudinal axis of the ski, clamped at the front end thereof and, when exiting, runs in guides 14 with the pivot point raised on the underside of the pivotable spring board 12.
