Abstract

The setting device for pretensioning a snowboard or skis has two upwardly projecting abutments (2, 2') to be fitted on the device (1) at a distance apart, a tension rod (3), a spring component (5) and/or a damping component (6), in which the components (5, 6), may be pretensioned by adjusters (4) to a greater or lesser extent. This arrangement makes it possible to preset the curvature of a snowboard or skis as desired.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Einstellen der Vorspannung bzw. Durchbiegung bei Snowboards oder Skis sowie deren Verwendung auf einem Snowboard oder Skis.The present invention relates to a device for adjusting the pretension or deflection in snowboards or skis and the use thereof on a snowboard or skis.

Skis insbesondere jedoch Snowboards weisen konstruktionsbedingt durch den besonderen Aufbau von verschiedenen Schichten aus Holz, Kunststoff und Metall eine Eigenstabilität auf Durchbiegung und Torsion auf. Sie kann bei den heutigen Konstruktionen nicht den Bedürfnissen des Fahrers angepasst werden. Das Snowboard verliert bei intensivem Gebrauch an Qualität, d.h. die Vorspannung bzw. Durchbiegung nimmt ab.Skis in particular, however, snowboards have inherent stability due to the special structure of different layers of wood, plastic and metal on deflection and torsion. With today's designs, it cannot be adapted to the needs of the driver. The snowboard loses quality when used intensively, i.e. the preload or deflection decreases.

Aufgabe der vorliegenden Erfindung ist die Schaffung einer Vorrichtung, welche eine variable und gefederte Einstellbarkeit dar Härte (Steifigkeit) des Snowboards oder Skis ermöglicht, abgestimmt auf die Bedürfnisse des Fahrers entsprechend seinem Gewicht, seinem Können und der jeweiligen Schneebeschaffenheit, um einen optimalen Kanteneinsatz zu ermöglichen. Es sollen damit auch die Schläge beim Fahren auf den Körper des Fahrers gedämpft und unerwünschte Schwingungen zur Verbesserung der Fahreigenschaften reduziert werden und möglichst die Lebensdauer des Snowboards erhöht werden.The object of the present invention is to provide a device which enables a variable and sprung adjustability of the hardness (stiffness) of the snowboard or ski, tailored to the needs of the driver in accordance with his weight, his ability and the respective snow conditions, in order to enable optimum use of the edges . It is also intended to dampen the impacts on the rider's body while driving, to reduce unwanted vibrations to improve the driving characteristics and to increase the life of the snowboard as far as possible.

Diese Aufgabe wird mit einer Einstellvorrichtung gelöst, welche sich erfindungsgemäss auszeichnet durch zwei im Abstand voneinander auf der Oberseite eines Snowboards oder Skis nach oben abstehend anzubringende Widerlager, durch eine zwischen letzterem angeordnete Druckstange, welche am einen Widerlager anliegt und im anderen frei längsverschiebbar geführt ist, wobei an der Druckstange in deren mittleren Bereich ein Anschlag vorgesehen ist und Zwischen diesem und dem die Druckstange längsverschieblich führenden Widerlager ein Feder- und/oder Dämpfungselement angeordnet ist, welches durch Veränderung des Abstandes zwischen Anschlag und dem genannten anderen Widerlager mehr oder weniger stark vorspannbar ist und durch Mittel, um den Abstand zwischen dem genannten anderen Widerlager und dem Anschlag frei einzustellen, derart, dass die beiden Widerlager durch die Vorspannung des Feder- und/oder Dämpfungselementes mit einstellbarer Kraft auseinandergedrückt werden und damit der Unterlage, d.h. dem Snowboard oder Ski im Bereich zwischen den Widerlagern eine mehr oder wenige ausgeprägte Durchbiegung auferlegen.This object is achieved with an adjusting device which, according to the invention, is distinguished by two abutments to be spaced apart from one another on the top of a snowboard or ski, and by a pressure rod arranged between the latter abuts on an abutment and is guided freely longitudinally in the other, a stop being provided on the push rod in the central region thereof and a spring and / or damping element is arranged between this and the abutment guiding the push rod in a longitudinally displaceable manner, which by changing the distance between Stop and said other abutment is more or less prestressable and by means to freely adjust the distance between said other abutment and the stop, such that the two abutments are pressed apart by the bias of the spring and / or damping element with adjustable force and thus impose a more or less pronounced deflection on the surface, ie the snowboard or ski in the area between the abutments.

Eine besonders vorteilhafte Ausführungsform des Erfindungsgegenstandes zeichnet sich dadurch aus, dass die Druckstange mindestens in einem Mittelabschnitt als Gewindestange mit den genannten Anschlag bildender aufgesetzter Verstellmutter ausgebildet ist, wobei die vorzugsweise gegen Verdrehung gesicherte Druckstange im einen Widerlager längsverschiebbar geführt ist und mit einer Anschlagfläche am anderen Widerlager anliegt und dass zwischen der die Einstellmittel bildenden Verstellmutter und dem längsverschiebbar gehaltenen Ende der Druckstange eine Druckfeder und/oder ein Dämpfungselement auf die Druckstange aufgesetzt ist, wobei Druckfeder und/oder Dämpfungselement durch Verstellen der Verstellmutter auf einen beliebig einstellbaren Wert vorspannbar ist.A particularly advantageous embodiment of the subject matter of the invention is characterized in that the push rod is formed at least in a central section as a threaded rod with the abutment adjusting nut forming the abovementioned stop, the push rod, which is preferably secured against rotation, being longitudinally displaceable in one abutment and with a stop surface on the other abutment abuts and that a compression spring and / or a damping element is placed on the pressure rod between the adjusting nut forming the adjusting means and the longitudinally displaceably held end of the push rod, the push spring and / or damping element being pretensionable by adjusting the adjusting nut to an arbitrarily adjustable value.

Als Einstellmittel kann auch eine auf Feder- und/oder Dämpfungselement einwirkende, an der Druckstange angebrachte Exzenter- oder Keilmechanik verwendet werden.An eccentric or wedge mechanism acting on the spring and / or damping element and attached to the push rod can also be used as the adjusting means.

Bei einer weiteren Variante bestehen die Einstellmittel aus einer Einrichtung, mit welcher mindestens eines der Widerlager in Richtung der Längsachse der Druckstange verstellt werden. Damit wird das Feder- und/oder Dämpfungselement ebenfalls mehr oder weniger stark vorgespannt.In a further variant, the adjusting means consist of a device with which at least one of the abutments is adjusted in the direction of the longitudinal axis of the push rod. So that the spring and / or damping element is also more or less biased.

Beim Einsatz solcher Vorrichtungen an Snowboards wird mindestens eine solche Vorrichtung im Bereich zwischen den Bindungen auf der Oberseite des Snowboards angebracht, gegebenenfalls jedoch mehrere nebeneinander, wobei die Vorrichtungen verschiedenartig aufgebaut sein können (z.B. eine mit Federelement, die andere mit Dämpferelement).When using such devices on snowboards, at least one such device is attached in the area between the bindings on the top of the snowboard, but possibly several next to one another, whereby the devices can be of different types (e.g. one with a spring element, the other with a damper element).

Bei der Verwendung an Skis muss die Vorrichtung längs im Bereich der Bindungsplatte (evtl. leicht grössere Dicke) eingebaut werden.When used on skis, the device must be installed lengthways in the area of the binding plate (possibly slightly thicker).

Die Erfindung wird nachstehend anhand von in der Zeichnung dargestellten Ausführungsbeispielen noch etwas näher erläutert. Es zeigen:

  • Fig. 1 rein schematisch ein Snowboard im Längsschnitt (etwa entlang der Mittellängslinie);
  • Fig. 2 ein mit einer Einstellvorrichtung nach der Erfindung ausgerüstetes Snowboard in schematischer Draufsicht;
  • Fig. 3 eine ähnliche Ansicht wie Fig. 2, mit zwei verschiedenartig aufgebauten, nebeneinander montierten Einstellvorrichtungen;
  • Fig. 4 eine Seitenansicht einer erfindungsgemässen Vorrichtung ebenfalls rein schematisch.
  • Fig. 5 eine Variante einer Verstelleinrichtung, und
  • Fig. 6 eine besonders bevorzugte Ausführungsform einer erfindungsgemässen Vorrichtung.
The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. Show it:
  • Figure 1 purely schematically a snowboard in longitudinal section (approximately along the central longitudinal line).
  • Figure 2 is a schematic top view of a snowboard equipped with an adjusting device according to the invention;
  • Fig. 3 is a view similar to Fig 2, with two differently constructed, side-by-side adjustment devices.
  • Fig. 4 is a side view of a device according to the invention also purely schematically.
  • 5 shows a variant of an adjusting device, and
  • 6 shows a particularly preferred embodiment of a device according to the invention.

Fig. 1 der Zeichnung zeigt einen prinzipiellen Längsschnitt durch ein Snowboard 1. Die Lauffläche des Snowboards 1 weist in der Regel eine vorbestimmte mittlere Vorspannung auf, welche sich in der Durchbiegung fo manifestiert, d.h. die Lauffläche bei unbelastetem Brett ist konkav.1 of the drawing shows a basic longitudinal section through a snowboard 1. The tread of the snowboard 1 generally has a predetermined mean prestress, which is manifested in the deflection f o , ie the tread is concave when the board is not under load.

Mit der erfindungsgemässen Vorrichtung kann nun die Durchbiegung f₁ der Lauffläche verändert werden (auf einen beliebigen Wert f₁ > fo). Damit ändern sich die Fahreigenschaften, oder die durch den Gebrauch bzw. Alterung sich reduzierende Grundvorspannung infolge Materialermüdung kann nachgestellt werden. Selbstverständlich kann durch eine solche Einstellung auch eine Abstimmung auf das individuelle Gewicht bzw. das Können des Fahrers erfolgen.With the device according to the invention, the deflection f 1 of the tread can now be changed (to any value f 1> f o ). This changes the driving characteristics, or the basic preload due to material fatigue that is reduced due to use or aging can be adjusted. Such an adjustment can of course also be adapted to the individual weight or the skill of the driver.

Bei Verwendung eines echten Dämpfungselementes können zudem auftretende Schläge wirksamer gedämpft werden als bei Einsatz nur eines Federelementes.If a real damping element is used, any impacts that occur can be dampened more effectively than if only one spring element is used.

Fig. 2 der Zeichnung zeigt in Draufsicht ein mit einer erfindungsgemässen Vorrichtung ausgerüstetes Snowboard 1. Die Vorrichtung 1, mit den beiden nach oben abstehenden Widerlagern 2,2', der Druckstange 3, den Verstellmitteln 4, dem Federelement 5 und dem Dämpfungselement 6, ist dabei im Abschnitt zwischen den beiden Bindungen 7,7' angeordnet.2 of the drawing shows a top view of a snowboard 1 equipped with a device according to the invention. The device 1, with the two abutments 2, 2 'projecting upwards, the push rod 3, the adjusting means 4, the spring element 5 and the damping element 6 arranged in the section between the two bonds 7,7 '.

Beim gezeigten Beispiel besteht die Vorrichtung aus den beiden die Widerlager bildenden Winkeln 2,2', welche zwischen den Bindungen 7,7' fest mit dem Brett 1 verbunden sind (aufgeschraubt) und einer die Druckstange bildenden Gewindestange 3 (diese weist zumindest im mittleren Abschnitt ein Gewinde auf). Auf der Gewindestange 3 befindet sich eine Verstellmutter 4, eine Druckfeder 5 und ein Dämpfungselement in Form eines Gummiblockes 6. Mit der Verstellmutter 4 kann die Vorspannung der Druckfeder 5 und des Dämpfungselementes 6 variiert und damit die Vorspannung bzw. Durchbiegung f₁ des Brettes beeinflusst werden. Bei dieser Anordnung mit Druckfeder und Dämpfungselement besteht zwischen den Kennlinien dieser beiden Elemente eine Abhängigkeit.In the example shown, the device consists of the two angles 2,2 'forming the abutments, which are firmly connected (screwed) between the bindings 7,7' to the board 1 and a threaded rod 3 forming the push rod (this has at least in the middle section a thread on). On the threaded rod 3 there is an adjusting nut 4, a compression spring 5 and a damping element in the form of a rubber block 6. With the adjusting nut 4, the bias of the compression spring 5 and the damping element 6 can be varied and thus the bias or deflection f 1 of the board can be influenced. In this arrangement with compression spring and damping element, there is a dependency between the characteristics of these two elements.

Grundsätzlich ist es auch möglich, dass die Vorrichtung lediglich mit einer Druckfeder oder nur mit einem Dämpfungselement ausgerüstet ist. Vorzugsweise werden aber beide Elemente auf einer Druckstange angeordnet. Es ist auch möglich, mehrere Vorrichtungen gleichen oder unterschiedlichen Aufbaus auf einem Snowboard vorzusehen.In principle, it is also possible for the device to have only one compression spring or only one Damping element is equipped. However, both elements are preferably arranged on a push rod. It is also possible to provide several devices of the same or different construction on a snowboard.

So zeigt z.B. Fig. 3 ein Snowboard mit zwei nebeneinander angeordneten Vorrichtungen 8 und 9, von denen die eine ein Federelement 8' und die andere ein Dämpfungselement 9' trägt. Bei dieser Ausführungsform dient die eine Vorrichtung 8 der Einstellung der Durchbiegung der Lauffläche, während die andere 9 hauptsächlich der Einstellung des Dämpfungsgrades dient.For example, Fig. 3 shows a snowboard with two juxtaposed devices 8 and 9, one of which carries a spring element 8 'and the other a damping element 9'. In this embodiment, one device 8 is used to adjust the deflection of the tread, while the other 9 is mainly used to adjust the degree of damping.

Fig. 4 zeigt den prinzipiellen Aufbau einer erfindungsgemässen Vorrichtung. Diese besteht aus zwei Widerlagern 10,11, einer Gewindestange 12, welche mit einer Schulter 13 am Widerlager 10 anliegt, einer Druckfeder 15 und einem Gummidämpfer 16, wobei Verstellmutter 14 und Dämpfer 16 frei verschiebbar auf die Stange 12 aufgesetzt sind. Die Gewindestange 12 ist im Widerlager 11 axial frei verschiebbar, vorzugsweise aber an diesem Ende gegen Verdrehung gesichert.4 shows the basic structure of a device according to the invention. This consists of two abutments 10, 11, a threaded rod 12, which rests with a shoulder 13 on the abutment 10, a compression spring 15 and a rubber damper 16, the adjusting nut 14 and damper 16 being freely displaceably placed on the rod 12. The threaded rod 12 is axially freely displaceable in the abutment 11, but is preferably secured against rotation at this end.

Durch Verdrehen der Verstellmutter 14 kann nun das Paket bestehend aus Druckfeder 15 und Dämpfungselement 16 mehr oder weniger vorgespannt werden, so dass die beiden Widerlager 10,11 durch die Vorspannkraft auseinandergedrückt werden und dank dem von den Widerlagern 10,11 gebildeten Hebel das Brett mehr oder weniger stark vorgespannt bzw. durchgebogen wird.By turning the adjusting nut 14, the package consisting of the compression spring 15 and damping element 16 can now be more or less pretensioned, so that the two abutments 10, 11 are pushed apart by the pretensioning force and, thanks to the lever formed by the abutments 10, 11, the board more or is less pretensioned or bent.

Fig. 4 zeigt, dass z.B. mindestens eines der Widerlager 10 in einer schlittenartigen Führung 10' auf dem Brett befestigbar ist, wobei über eine geeignete Verstelleinrichtung (z.B. ebenfalls Gewindestange) das Widerlager 10 in der Führung 10' verschoben werden kann, um anstelle der Verstellmutter 14 (welche durch einen festen Anschlag zu ersetzen wäre) Feder- und Dämpfungselement 15 bzw. 16 vorzuspannen.4 shows that, for example, at least one of the abutments 10 can be fastened in a slide-like guide 10 'on the board, with the abutment 10 in the guide 10' being able to be displaced by means of a suitable adjusting device (for example also a threaded rod), instead of the adjusting nut 14 (which would have to be replaced by a fixed stop) to prestress the spring and damping element 15 or 16.

Fig. 5 zeigt rein schematisch ein weiteres Verstellmittel in Form eines Exzenters 37, welches sich gegen einen festen Anschlag 38 (anstelle Verstellmutter 14) auf der Stange 12 anlegen und diesen verschieben kann. Der Exzenter 37 müsste in den verschiedenen Winkelstellungen in dem Fachmann bekannter Weise feststellbar sein.Fig. 5 shows purely schematically another adjusting means in the form of an eccentric 37, which can bear against a fixed stop 38 (instead of adjusting nut 14) on the rod 12 and move it. The eccentric 37 should be lockable in the various angular positions in a manner known to those skilled in the art.

Fig. 6 der Zeichnung zeigt eine besonders vorteilhafte Ausführungsform des Erfindungsgegenstandes. Zwischen den beiden Widerlagern 17 und 18 ist eine dreiteilige Druckstange 19', 19'', 19''' drehbar gelagert (in den Bohrungen 17' bzw. 18'), wobei das eine Ende der Druckstange in der Bohrung 17' zudem längsverschieblich ist).6 of the drawing shows a particularly advantageous embodiment of the subject matter of the invention. Between the two abutments 17 and 18, a three-part push rod 19 ', 19' ', 19' '' is rotatably mounted (in the bores 17 'and 18'), wherein one end of the push rod in the bore 17 'is also longitudinally displaceable ).

Auf dem als Gewindestange ausgebildeten Abschnitt 19' der Druckstange sitzt der Anschlag 20, gegen welchen die Druckfeder 21 einerends anliegt. Das andere Ende der Druckfeder 21 liegt gegen den Endabschlussdeckel 23 eines die Druckstange 19' umgebenden Rohres 22 an. Dieses Rohr 22 liegt am Widerlager 17 an und sorgt dafür, dass die beiden Widerlager 17,18 in Abhängigkeit der Spannung der Feder 21 mehr oder weniger stark auseinandergedrückt werden (die Feder nimmt selbstverständlich auch wechselnde Kräfte im Betrieb des Snowboards auf, ohne diese jedoch wesentlich zu dämpfen). Der verschiebbare Anschlag 20 weist eine Gewindebohrung auf und sitzt auf dem Gewinde des Druckstangenabschnittes 19'. Ueber einen radial abstehenden Stift 24 ist der Anschlag (Gewindemuffe) 20 in einem Längsschlitz 25 des Rohres 22 geführt, so dass durch Verdrehen der Gewindestange 19 bei gleichzeitigem Festhalten des Rohres 22 der Anschlag 20 verstellt werden kann (und damit die Federvorspannung). Die Stellung des Stiftes 24 im Schlitz 25 zeigt auch gleichzeitig die Federvorspannung an.The stop 20, against which the compression spring 21 rests at one end, is seated on the section 19 'of the push rod which is designed as a threaded rod. The other end of the compression spring 21 lies against the end cover 23 of a tube 22 surrounding the pressure rod 19 '. This tube 22 rests on the abutment 17 and ensures that the two abutments 17, 18 are pushed apart to a greater or lesser extent depending on the tension of the spring 21 (the spring naturally also absorbs changing forces during operation of the snowboard, but without them significantly) to dampen). The displaceable stop 20 has a threaded bore and is seated on the thread of the push rod section 19 '. The stop (threaded sleeve) 20 is guided in a longitudinal slot 25 of the tube 22 via a radially projecting pin 24, so that by turning the threaded rod 19 while holding the tube 22, the stop 20 can be adjusted (and thus the spring preload). The position of the pin 24 in the slot 25 also indicates the spring preload.

Der mit den Abschnitten 19' und 19''' drehbar verbundene Abschnitt 19'' der Druckstange 19 (Abschnitt 19' ist drehfest in Abschnitt 19'' eingesteckt, während Abschnitt 19'' einteilig oder verschraubt mit Abschnitt 19''' ausgebildet ist) dient als Träger eines Dämpfungsgliedes. Dieses arbeitet wie folgt: Zwischen einer Schulter 26 und einer auf ein Gewinde 27 aufgesetzten Gewindemuffe 28 ist ein Gummielement 29 eingesetzt, wobei Schulter 26 und Gummielement 29 im Innern des zylindrischen Rohres 22 liegen. Durch mehr oder weniger starkes Anziehen der Gewindemuffe 28 wird das Gummielement 29 mehr oder weniger stark aufgeweitet und gegen die Innenwand des Rohres 22 gepresst, was durch Reibung eine Dämpfungswirkung ausübt, sobald sich die Druckstange 19 in Längsrichtung zum Rohr 22 verschiebt. Die auf dem Gewinde 27 des Druckstangenabschnittes 19'' sitzende Gewindemuffe 28 dringt mit einem Ende ebenfalls in das Rohr 22 ein und weist im übrigen einen dem Rohr 22 entsprechenden Druchmesser auf.The section 19 '' of the push rod 19 which is rotatably connected to the sections 19 'and 19' '' (section 19 'is rotatably inserted into section 19' ', while section 19' 'is formed in one piece or screwed to section 19' '') serves as a support for an attenuator. This works as follows: A rubber element 29 is inserted between a shoulder 26 and a threaded sleeve 28 placed on a thread 27, the shoulder 26 and the rubber element 29 lying inside the cylindrical tube 22. By tightening the threaded sleeve 28 to a greater or lesser extent, the rubber element 29 is expanded to a greater or lesser extent and pressed against the inner wall of the tube 22, which exerts a damping effect due to friction as soon as the push rod 19 moves in the longitudinal direction to the tube 22. The threaded sleeve 28 seated on the thread 27 of the push rod section 19 ″ likewise penetrates into the tube 22 at one end and has a diameter corresponding to the tube 22.

Der letzte Abschnitt 19''' der Druckstange ist im Durchmesser stark erweitert (entsprechend dem Durchmesser des Rohres 22) und weist eine geriffelte Oberfläche auf. Damit lässt sich durch Verdrehen der Druckstange bei gleichzeitigem Festhalten des Rohres 22 die Vorspannung der Druckfeder 21 einstellen. Es mag dazu sinnvoll sein, die Gewindemuffe 28 für diesen Einstellvorgang zu lösen und anschliessend wieder anzuziehen, um die gewünschte Dämpfung zu regulieren.The last section 19 '' 'of the push rod is greatly expanded in diameter (corresponding to the diameter of the tube 22) and has a corrugated surface. Thus, the pretension of the compression spring 21 can be set by turning the push rod while holding the tube 22 at the same time. It may make sense to loosen the threaded sleeve 28 for this adjustment process and then tighten it again in order to regulate the desired damping.
