Description

Vorrichtung zur Beeinflussung von Biegebewegungen eines SkisDevice for influencing bending movements of a ski
Die Erfindung betrifft eine Vorrichtung zur Beeinflussung von Biegebewegungen eines Skis, mit einem in Skilängsrichtung angeordneten bzw. anbringbaren Schubteil, welches einen skifest angeordneten bzw. anbringbaren Abschnitt sowie einen davon in Skilängsrichtung beabstandeten und in Skilängsrichtung verschiebbaren Bereich aufweist, der mit einem skifesten bzw. skifest anbringbaren Widerlager über Kraftübertragungsmittel koppelbar bzw. gekoppelt ist.The invention relates to a device for influencing bending movements of a ski, with a pushing part arranged or attachable in the longitudinal direction of the ski, which has a section arranged or attachable in the manner of a ski and a region spaced therefrom in the longitudinal direction of the ski and displaceable in the longitudinal direction of the ski, with an area which is fixed or attached to the ski attachable abutment is coupled or coupled via power transmission means.
Derartige Vorrichtungen sind teilweise serienmäßig in Skibindungen integriert. Dabei ist das Schubteil flachbandartig biegbar ausgebildet, wobei ein Ende des Flachbandes unterhalb des fersenseitigen Bindungsaggregates skifest gehaltert und das andere in Skilängsrichtung bewegliche Ende in skifesten Führungen unterhalb des zehenseitigen Bindungsteiles geführt ist. Sobald der Ski Biegebewegungen ausführt, verschiebt sich das vordere Ende des flachbandartigen Schubteiles in Skilängsrichtung relativ zur Skioberseite, weil das Schubteil außerhalb der neutralen Biegezone des Skis liegt. Bei stärkerer Durchbiegung des Skis stützt sich nun das vordere Ende des Schubteiles mit gefederten Zungen auf einem verstellbaren skiseitigen Widerlager ab, mit der Folge, daß der Ski steuerbar versteift wird. Aufgabe der Erfindung ist es nun, bei einer Vorrichtung der eingangs angegebenen Art eine an unterschiedliche Kraftuber- tragungsmittel gut anpassbare Konstruktion zu schaffen.Such devices are partially integrated into ski bindings as standard. The push part is designed to be bendable in the manner of a flat band, one end of the flat band being held ski-like underneath the heel-side binding unit and the other end movable in the longitudinal direction of the ski being guided in ski-fixed guides below the toe-side binding part. As soon as the ski makes bending movements, the front end of the flat band-like thrust part shifts in the longitudinal direction of the ski relative to the top of the ski, because the thrust part lies outside the neutral bending zone of the ski. In the event of greater deflection of the ski, the front end of the pushing part is now supported by spring-loaded tongues on an adjustable abutment on the ski side, with the result that the ski is stiffened in a controllable manner. The object of the invention is now to provide a construction which can be easily adapted to different force transmission means in a device of the type specified at the outset.
Diese Aufgabe wird erfmdungsgemaß dadurch gelost, daß zwischen dem Kraftubertragungsmittel und dem verschiebbaren Bereich eine Ubersetzungsvorrichtung zwischengeschaltet ist, die Bewegungshube des verschiebbaren Bereiches relativ zum Ski mit vorgegebenen bzw. vorgebbarem Übersetzungsverhältnis auf das Kraftubertragungsmittel übertragt.This object is achieved according to the invention in that a translation device is interposed between the force transmission means and the displaceable area and transmits the movement stroke of the displaceable area relative to the ski to the force transmission means with a predetermined or predefinable transmission ratio.
Die Erfindung beruht auf dem allgemeinen Gedanken, das Maß des wirksamen Verschiebehubes des verschiebbaren Bereiches des Schubteiles durch eine Getriebeanordnung zu verandern, um eine optimale Anpassung an das jeweilige Kraftubertragungsmittel zu ermöglichen.The invention is based on the general idea of changing the extent of the effective displacement stroke of the displaceable region of the thrust part by means of a gear arrangement in order to enable an optimal adaptation to the respective force transmission means.
Dies ist insbesondere dann wichtig und vorteilhaft, wenn zwischen dem verschiebbaren Bereich des Schubteiles und dem skifesten Widerlager ein hydraulischer Dampfer wirksam sein soll. Derartige Dampfer lassen sich deutlich leichter abstimmen, wenn große Hubbewegungen auftreten. Dementsprechend wird die Erfindung be hydraulischen Dampfern dazu benutzt, die Hube des verschiebbaren Bereiches des Schubteiles in vergrößerte Hube des Stoßdampfers umzusetzen.This is particularly important and advantageous if a hydraulic steamer is to be effective between the displaceable area of the thrust part and the ski-fixed abutment. Such steamers are much easier to tune when large lifting movements occur. Accordingly, the invention be used hydraulic dampers to implement the stroke of the displaceable portion of the thrust part in an enlarged stroke of the shock absorber.
Im übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche sowie nachfolgende Erläuterung der Zeichnung verwiesen, anhand der besonders bevorzugte Ausfuhrungsformen der Erfindung naher beschrieben werden.Otherwise, with regard to preferred features of the invention, the claims and the following explanation of the Drawing referenced, are described in more detail with reference to the particularly preferred embodiments of the invention.
Dabei zeigtIt shows
Fig. 1 eine schematisierte Draufsicht auf eine erste Ausfuhrungsform,1 is a schematic plan view of a first embodiment,
Fig. 2 ein Schnittbild entsprechend der Schnittlinie II-II m Fig. 1,2 is a sectional view corresponding to the section line II-II m Fig. 1,
Fig. 3 eine Draufsicht auf die Unterseite einer zweiten Ausfuhrungsform undFig. 3 is a plan view of the underside of a second embodiment and
Fig. 4 eine perspektivische Ansicht der zweiten Ausfuhrungsform.Fig. 4 is a perspective view of the second embodiment.
Bei der Ausfuhrungsform der Fig. 1 und 2 ist auf der Oberseite eines Skis 1 ein flachbandartiges Schubteil 2 angeordnet, wobei das in der Zeichnung rechte Ende des Schubteiles 2 skifest angeordnet und dazu beispielsweise mit dem Ski verschraubt ist. Das in Fig. 1 linke Ende des Schubteiles 2 ist als freies Ende ausgebildet und verschiebt sich dementsprechend relativ zum Ski 1 in Skilangsnchtung, wenn der Ski 1 durchgebogen wird. Dies beruht auf der Tatsache, daß das Schubteil 2 außerhalb, und zwar oberhalb, der neutralen Biegezone des Skis 1 angeordnet ist.In the embodiment of FIGS. 1 and 2, a flat band-like thrust part 2 is arranged on the top of a ski 1, the right end of the thrust part 2 in the drawing being arranged in a ski-like manner and for this purpose, for example, screwed to the ski. The left end of the pushing part 2 in FIG. 1 is designed as a free end and accordingly shifts relative to the ski 1 in the long ski direction when the ski 1 is bent. This is based on the fact that the thrust part 2 is arranged outside, and above, the neutral bending zone of the ski 1.
Im übrigen ist das linke freie Ende des Schubteiles 2 mit einem Schieber 3 verbunden bzw. als solcher ausgebildet, der in einer skifesten Fuhrung 4 in Skilangsnchtung verschiebbar aufgenommen ist. Diese Fuhrung besteht im wesentlichen aus einer auf der Skioberseite befestigten Platte 4' und an den Langsrander der Platte 4' ausgebildeten U-Profilen 4", welche einander mit ihren Konkavseiten zugewandt sind. In diese U-Profile 4" ragen Langsrander des Schiebers 3 hinein, so daß der Schieber 3 nur in Skilangsnchtung bewegbar ist.In addition, the left free end of the thrust part 2 is connected to a slide 3 or is formed as such, which is slidably received in a ski-fixed guide 4 in the longitudinal direction. This leadership essentially exists from a plate 4 'fastened on the upper side of the ski and U profiles 4 "formed on the long edges of the plate 4', which face each other with their concave sides. Long edges of the slider 3 protrude into these U profiles 4" so that the slide 3 can only be moved in the long ski direction.
Auf der Platte 4' der Fuhrung 4 ist ein Lagerzapfen 5 angeordnet, welcher einen doppelarmigen Hebel 6 schwenkbar lagert. Dieser Hebel 6 ist mit einem kurzen Arm am Schieber 3 angelenkt, wobei ein am Schieber 3 angeordneter Gelenkbolzen 7 in ein Langloch 8 am Hebel 6 hineinragt.On the plate 4 'of the guide 4, a bearing pin 5 is arranged which pivotally supports a double-armed lever 6. This lever 6 is articulated with a short arm on the slide 3, a pivot pin 7 arranged on the slide 3 projecting into an elongated hole 8 on the lever 6.
Der längere Arm des Hebels 6 ist mit einem Stößel 9 gelenkig verbunden, welcher die Kolbenstange eines fest an der Fuhrung 4 angeordneten hydraulischen Dampfers 10 bildet. Dabei ragt ein am Stößel 9 befestigter Gelenkbolzen 11 in ein weiteres Langloch 12 am Hebel 6 hinein.The longer arm of the lever 6 is connected in an articulated manner to a plunger 9, which forms the piston rod of a hydraulic steamer 10 arranged fixedly on the guide 4. In this case, a hinge pin 11 fastened to the plunger 9 projects into a further elongated hole 12 on the lever 6.
Durch die Langlocher 8 und 12 wird gewährleistet, daß die Hebelarme des Hebels 6 bei Verschiebung von Stößel 9 und Schieber 3 in Skilangsnchtung zwangsfrei zu schwenken vermögen.The elongated holes 8 and 12 ensure that the lever arms of the lever 6 are able to pivot freely when the plunger 9 and slide 3 are moved in the longitudinal direction of the ski.
Am Stößel 9 ist ein Kragen 13 angeordnet, welcher als sto- ßelseitiges Widerlager einer zum Stößel 9 konzentrischen Schraubendruckfeder 14 dient, deren anderen Ende auf der zugewandten Stirnseite des Dampfers 10 abgestutzt ist. Wenn der Ski 1 Biegebewegungen ausfuhrt, verschiebt sich der Schieber 3 in der Fuhrung 4 in Skilangsnchtung, mit der Folge, daß der Hebel 6 eine Schwenkbewegung um den Lagerzapfen 5 ausfuhrt, so daß auch der Stößel 9 in Skilangsnchtung bewegt wird. Aufgrund der vergleichsweise großen Lange des stoßelseitigen Hebelarmes des Hebels 6 fuhrt der Stößel 9 im Vergleich zum Schieber 3 große Verschiebehube aus. Dies ist vorteilhaft, weil sich für den Dampfer 10 ein besonders gut reproduzierbares Betriebsverhalten ergibt, wenn mit größeren Hüben gerechnet werden kann.A collar 13 is arranged on the plunger 9, which serves as a plunger-side abutment of a helical compression spring 14 concentric with the plunger 9, the other end of which is supported on the facing end face of the steamer 10. When the ski 1 performs bending movements, the slide 3 moves in the guide 4 in the longitudinal direction of the ski, with the result that the lever 6 executes a pivoting movement about the journal 5, so that the plunger 9 is also moved in the longitudinal direction. Due to the comparatively large length of the lever arm 6 on the ram side of the lever 6, the ram 9 performs a large displacement stroke in comparison with the slide 3. This is advantageous because the steamer 10 has a particularly reproducible operating behavior if larger strokes can be expected.
Im dargestellten Beispiel wird der Stößel 9 aus dem Gehäuse des Dampfers 10 herausgezogen, wenn der Ski 1 eine Biegung ausfuhrt, bei der sich die Skienden relativ zur Skimitte in Aufwartsπchtung bewegen. Gleichzeitig wird bei dieser Art der Biegebewegung des Skis 1 die konzentrisch zum Stößel angeordnete Schraubendruckfeder 14 zunehmend entspannt. Bei der Ruckbiegung des Skis 1 wird der Stößel 9 in den Dampfer eingeschoben, gleichzeitig wird die Schraubendruckfeder 14 zunehmend gespannt.In the example shown, the plunger 9 is pulled out of the housing of the steamer 10 when the ski 1 makes a bend in which the ski ends move in an upward direction relative to the center of the ski. At the same time, with this type of bending movement of the ski 1, the helical compression spring 14 arranged concentrically with the plunger is increasingly relaxed. When the ski 1 bends back, the plunger 9 is pushed into the steamer, at the same time the helical compression spring 14 is increasingly tensioned.
Bei entsprechender Auslegung des Dampfers 10 kann der Stößel 9 in der Zugstufe, d.h. bei einer Verschiebung m Fig. 1 nach rechts, vergleichsweise leicht bewegt werden, wahrend einer Bewegung in der Druckstufe, d.h. m Fig. 1 nach links, ein größerer Widerstand auftritt. Dementsprechend werden Biegebewegungen des Skis 1 nicht bzw. schwach gedampft, wahrend der Ruckbiegung eine erhöhte Dampfung auftritt. Grundsatzlich ist jedoch auch eine andere Abstimmung des Dampfers 10 möglich, derart, daß in der Zugstufe eine verstärkte Dampfung auftritt oder Zug- und Druckstufe gleiche Dampfungswirkung haben. Damit können dann Biegebewegungen des Skis 1 verstärkt oder in gleicher Weise wie Rückbiegungen des Skis 1 bedampft werden.With a corresponding design of the steamer 10, the plunger 9 can be moved comparatively easily in the rebound stage, ie with a displacement m FIG. 1 to the right, while a movement in the compression stage, ie m FIG. 1 to the left, a greater resistance occurs. Accordingly, bending movements of the ski 1 are not or only weakly damped, while increased bending occurs during the bending back. In principle, however, a different tuning of the steamer 10 is also possible, such that increased damping occurs in the rebound stage or the rebound and compression stages have the same damping effect. In this way, bending movements of the ski 1 can then be intensified or steamed in the same way as backbends of the ski 1.
Bei der in den Fig. 3 und 4 dargestellten Ausführungsform ist das Schubteil als steife Standplatte 20 für einen nicht dargestellten Skischuh ausgebildet, der auf der Standplatte 20 durch darauf angeordnete, nicht dargestellte fersenseiti- ge und zehenseitige Bindungsaggregate festgehalten wird.In the embodiment shown in FIGS. 3 and 4, the thrust part is designed as a rigid base plate 20 for a ski boot, not shown, which is held on the base plate 20 by heel-side and toe-side binding units, not shown, arranged thereon.
Das in der Zeichnung rechte Ende der Standplatte 20 ist auf dem Ski mit Schrauben od.dgl. fest gehaltert, die dazu in Schraublocher 15 eingesetzt werden.The right end of the base plate 20 in the drawing is on the ski with screws or the like. firmly held, which are used in screw punches 15.
Das in der Zeichnung linke Ende der Standplatte 2 ist in einer Fuhrung 40 m Skilangsrichtung verschiebbar geführt. Diese fest auf dem Ski 1 angeordnete Führung 40 ähnelt prinzipiell der Fuhrung 4 in den Fig. 1 und 2. Neben einer skifesten Platte 40' besitzt die Fuhrung 40 seitliche U-Profile 40", in die die Standplatte 20 mit an ihr angeformten seitlichen Langsstegen langsverschiebbar eingreift.The left end of the base plate 2 in the drawing is displaceably guided in a 40 m long ski direction. This guide 40, which is fixedly arranged on the ski 1, in principle resembles the guide 4 in FIGS. 1 and 2. In addition to a ski-fixed plate 40 ', the guide 40 has lateral U-profiles 40 "into which the base plate 20 with longitudinal longitudinal webs molded onto it engages slowly.
Unterhalb der genannten Langsstege der Standplatte 20 sind an den U-Profilen 40 der Fuhrung 40 Offnungen 41 angeordnet, in die im wesentlichen in Skiquerrichtung erstreckte Kipphebel 42 hineinragen, welche zwischen der Platte 40' der Fuhrung 40 und der Standplatte 20 angeordnet und einander mit ihren freien Enden zugewandt sind, wobei die vorgenannten Offnungen 41 die Schwenklager der Kipphebel 42 bilden. Diese Kipphebel können als flachbandartige Teile mit zur Oberseite des Skis 1 paralleler Flachbandebene ausgebildet sein .Below said longitudinal webs of the base plate 20, openings 41 are arranged on the U-profiles 40 of the guide 40, into which rocker arms 42, which extend essentially in the direction of the ski, project, which extend between the plate 40 ' Guide 40 and the base plate 20 are arranged and facing each other with their free ends, the aforementioned openings 41 forming the pivot bearings of the rocker arms 42. These rocker arms can be designed as flat ribbon-like parts with a flat ribbon plane parallel to the top of the ski 1.
Auf den dem skifesten Ende bzw. den Schraublochern 15 der Standplatte 20 zugewandten Seiten der Kipphebel 42 sind auf der Unterseite der Standplatte 20 Vorsprunge, beispielsweise in Form von Zapfen 43, angeordnet, welche an jedem Kipphebel 42 zwischen dessen Enden seitlich anliegen.On the sides of the rocker arm 42 facing the ski-fixed end or the screw holes 15 of the base plate 20, projections are arranged on the underside of the base plate 20, for example in the form of pins 43, which lie laterally on each rocker arm 42 between its ends.
Auf der von den Vorsprüngen bzw. Zapfen 43 abgewandten Seite liegen die Kipphebel 42 mit ihren freien Enden an einem Pufferteil 44 an, welches an der Kolbenstange eines in Ski- langsrichtung angeordneten hydraulischen Dampfers 10 angeordnet ist. Dessen Dampferzylinder 10' ist zwischen der Standplatte 20 und der Platte 40' der Fuhrung 40 in schlitzartigen Aussparungen der Standplatte 20 sowie der Platte 40' formschlussig gehaltert, wobei das vom Pufferteil 44 abgewandte Ende des Dampferzylinders 10' an einem mit der Führung fest verbundenen Widerlager 45 in Skilangsrichtung einstellbar gehaltert bzw. abgestützt ist.On the side facing away from the projections or pins 43, the free ends of the rocker arms 42 bear against a buffer part 44 which is arranged on the piston rod of a hydraulic steamer 10 arranged in the direction of the ski. Whose steam cylinder 10 'is positively held between the base plate 20 and the plate 40' of the guide 40 in slot-like recesses of the base plate 20 and the plate 40 ', the end of the steam cylinder 10' facing away from the buffer part 44 being connected to an abutment firmly connected to the guide 45 is adjustably supported or supported in the ski longitudinal direction.
Ggf. kann zwischen dem Pufferteil 44 und dem zugewandten Ende des Dämpferzylinders 10' eine zur Kolbenstange des Damp- fers 10 konzentrische Schraubendruckfeder (nicht dargestellt) eingespannt bzw. angeordnet sein.Possibly. can between the buffer part 44 and the facing end of the damper cylinder 10 'to the piston rod of the steam fers 10 concentric helical compression spring (not shown) can be clamped or arranged.
Wenn der Ski 1 Biegebewegungen ausfuhrt, verschiebt sich das in der Fuhrung 40 gehalterte Ende der Standplatte 20 in Skilangsnchtung. Dabei drucken die Vorsprunge bzw. Zapfen 43 die Kipphebel 42 unter Schwenkung gegen das Pufferteil 44, so daß der Kolben des Dampfers 10 in den Dampferzylinder 10' eingeschoben wird. Da die Vorsprunge bzw. Zapfen 43 an den Kipphebeln 42 m einem größeren Abstand von den am Pufferteil 44 anliegenden freien Enden der Kipphebel 42 angreifen, fuhrt die Kolbenstange des Dampfers 10 eine Hubbewegung aus, deren Maß deutlich großer ist, als das Maß der Relativver- schiebung zwischen Standplatte 20 und Fuhrung 40. Das Maß der Hububersetzung wird durch das Verhältnis zwischen der Lange des Kipphebels 42 und dem Abstand des jeweiligen Vorsprunges bzw. Zapfens 43 vom Schwenklager (Öffnung 41) des Kipphebels 42 bestimmt.When the ski 1 performs bending movements, the end of the base plate 20 held in the guide 40 moves in the longitudinal direction of the ski. The projections or pins 43 press the rocker arm 42 by pivoting against the buffer part 44, so that the piston of the steamer 10 is inserted into the steamer cylinder 10 '. Since the projections or pins 43 on the rocker arms 42 m engage a greater distance from the free ends of the rocker arms 42 which are in contact with the buffer part 44, the piston rod of the steamer 10 carries out a lifting movement, the dimension of which is significantly greater than the dimension of the relative displacement. slide between the base plate 20 and the guide 40. The extent of the stroke ratio is determined by the ratio between the length of the rocker arm 42 and the distance of the respective projection or pin 43 from the pivot bearing (opening 41) of the rocker arm 42.
Abweichend von der dargestellten Ausfuhrungsform können die Kipphebel 42 an ihren einander zugewandten Enden auch gelenkig miteinander verbunden sein, z.B. durch ein Foliengelenk, wenn die Kipphebel gemäß einer vorteilhaften Ausfuhrungsform aus Kunststoff bestehen. In a departure from the embodiment shown, the rocker arms 42 can also be articulated at their mutually facing ends, e.g. through a film hinge if the rocker arms consist of plastic according to an advantageous embodiment.
