  • a major disadvantage of this device called Monoski is that the legs of the driver in the oblique travel and in the curve are in an unnatural parallel position, which affects a loose ride and swing, therefore, can lead to rapid fatigue and even crashes.
  • a permanent position of the feet in this situation also makes higher demands on the driver's balance, which complicates the learning process and thus counteracts the goal, namely to facilitate the learning of skiing, that not two, but only one ski must be controlled and controlled , It is therefore not surprising that the Monoski in this form never prevailed on the market.
  • a second, also known embodiment of the type mentioned also uses a normal, or at most slightly widened ski of known type, but the two ski bindings are mounted in the middle region of the ski behind each other, so to speak directly on the longitudinal center axis of the ski and at a longitudinal distance from each other, which corresponds approximately to the average foot length of an adult person.
  • Such a position and orientation of the bindings forces the rider into a permanent lunge position over the longitudinal central axis of the ski, which places high demands on balance, thereby prolonging the learning phase and increasing the fall frequency.
  • the third type of single-board ski which has also been known for years, differs from the one described above in that the board is extremely wide, even more than twice as wide as a traditional ski. This is necessary because the bindings and thus the shoes are positioned at an angle of up to 90 ° to the longitudinal center axis of the board, while the distance of the bonds from each other is so large that the driver is in a position of stare. Sometimes the binding for the back foot is even set a bit backwards. The position is similar to that of the skater on the street or the surfboard athlete on the water. This is also the reason why this single board ski has been named Snow Board.
  • the body is directed when sloping on a slope in one direction to the slope, in the other direction but directed downhill.
  • This rigid, turned away from the direction of travel shoe and leg position makes the novice big trouble and therefore has countless crashes in the learning phase result. This is basically an unnatural, often uncomfortable and therefore often tiring position of the driver on the board.
  • a major disadvantage of alignment and distance of the bindings and shoes on the Snow Board is that it is technically possible only with great effort to provide security bonds for this. Because a solution in which only one bond releases the shoe would be more dangerous here than rigid, non-triggering bonds. It would therefore have to ensure that both shoes are released at the same time, which is possible only at the cost of a considerable technical effort.
  • the object of the present invention is to provide new ski sports equipment, which still offers the advantages of these types, but completely or largely eliminates the disadvantages.
  • This sports equipment is to be suitable in one embodiment for skiing on snow, in an alternative embodiment for water skiing. It should in particular allow changes in the foot position on a monoski while driving, and in certain variants, the pivoting of the feet away from the direction of travel, as well as the track spacing of the feet make it variable.
  • the ski sports equipment should also take into account safety aspects, and a detachment when large forces occur, both feet simultaneously from the bond as well as a foot can release individually from the bond when the same is exposed to excessive forces.

  • Each binding is mounted on a carriage, which is mobile on a fixed running rail sliding freely. The front and rear ends of the two rails overlap. The bindings therefore run obliquely to the longitudinal direction of the snowboard, depending on the displacement position.
  • the snowboard binding according to DE 197 10 436 A1 is longitudinally displaceable parallel to the longitudinal axis of the snowboard, wherein the movements can be guided via a positive guide, so that they are displaced in dependence on each other.

  • the spacing of the binding plates decreases substantially in width, so that the track width of the feet is reduced , and the outer edges of the binding plates run within the width of the monoski. This is especially important if the terrain is steep or if there is a steep incline in the curve: it prevents the slope-closer or bow-inner shoe from touching the surface. When cornering or cornering, there is only a single edge and it is important that the loaded foot is over this edge .

The stronger the lunge - whether to the left or right - the narrower the track, that is the distance between the two binding plates or feet of the driver. In the position with maximum lunge as in FIGS. 5 and 6 shown you can see that the binding plates are now above the monoski 100 and therefore no longer project beyond it.
  • the bindings described above can also be formed as loops, from which the feet can be released while driving. It may also be advantageous to mount the binding plates on the platform so as to be displaced both longitudinally and perpendicular to the board surface standing axis can be rotated, either within a limited angle or all around up to 360 degrees. It may also be useful to technically ensure that the movements of the binding plates and the interaction of these movements takes place against spring force, are installed in the springs, for example, metal, plastic or rubber.
  • the binding plates are mounted on the pedestal such that in the basic position there is a normal lateral distance of the shoes from each other and thus a natural, loose leg and body position can be assumed for the fall-line ride, and that when the plates are displaced in the longitudinal direction, the lateral spacing of the shoes from each other is reduced, that is, the binding plates easily approach the longitudinal center line of the ski.
  • This has the advantage that the outside of the bow inner shoe in the curve no longer protrudes from the ski edge, whereby the risk of extremely slanted in the curve with the shoe to touch the snow and then slide away, is virtually eliminated.

Description

Gegenstand der vorliegenden Erfindung ist ein Monoski das heisst ein Sportgerät, welches aus einem einzelnen Ski besteht, auf welchem zwei Bindungen montiert sind. Es ist ein Einsatz auf Schnee oder in einer anderen Ausführung als Wasserski oder als Skateboard möglich.The subject of the present invention is a monoski, ie a sports device, which consists of a single ski on which two bindings are mounted. It is a use on snow or in a different design than water skiing or skateboard possible.

Es sind bereits verschiedene Schneesport Geräte dieser Gattung bekannt. Bei einer ersten Ausführungsform wird ein normaler oder etwas verbreiterter Ski bekannter Art verwendet, in dessen mittlerem Bereich ein Aufbau befestigt ist, welcher Träger von zwei Skibindungen bekannter Art ist, wobei diese Skibindungen nebeneinander, symmetrisch zur Längs-Mittelachse des Skis, montiert sind.There are already several snow sports equipment of this genus known. In a first embodiment, a normal or slightly widened ski of known type is used, in the middle region of which a structure is fastened, which is the carrier of two ski bindings of known type, these ski bindings being mounted side by side, symmetrically with respect to the longitudinal center axis of the ski.

Ein wesentlicher Nachteil dieses als Monoski bezeichneten Gerätes besteht darin, dass sich die Beine des Fahrers in der Schrägfahrt und in der Kurve in einer unnatürlichen Parallelstellung befinden, was ein lockeres Fahren und Schwingen beeinträchtigt, deshalb zu raschen Ermüdungserscheinungen und gar zu Stürzen führen kann. Eine permanente Stellung der Füsse in dieser Lage stellt zudem höhere Ansprüche an das Gleichgewicht des Fahrers, was den Lernprozess erschwert und damit dem Ziel entgegenwirkt, nämlich das Erlernen des Skifahrens dadurch zu erleichtern, dass nicht zwei, sondern nur ein Ski kontrolliert und gesteuert werden muss. Es ist deshalb nicht verwunderlich, dass sich der Monoski in dieser Form auf dem Markt nie durchsetzte.A major disadvantage of this device called Monoski is that the legs of the driver in the oblique travel and in the curve are in an unnatural parallel position, which affects a loose ride and swing, therefore, can lead to rapid fatigue and even crashes. A permanent position of the feet in this situation also makes higher demands on the driver's balance, which complicates the learning process and thus counteracts the goal, namely to facilitate the learning of skiing, that not two, but only one ski must be controlled and controlled , It is therefore not surprising that the Monoski in this form never prevailed on the market.

Eine zweite, ebenfalls bekannte Ausführungsform der genannten Gattung verwendet auch einen normalen, oder höchstens leicht verbreiterten Ski bekannter Art, wobei aber die zwei Skibindungen im Mittelbereich des Skis hintereinander, sozusagen direkt auf der Längsmittelachse des Skis und in einem Längs-Abstand voneinander montiert sind, der etwa der mittleren Fusslänge einer erwachsenen Person entspricht. Eine solche Position und Ausrichtung der Bindungen zwingt den Fahrer in eine permanente Ausfallschritt-Stellung über der Längsmittelachse des Skis, was hohe Ansprüche an das Gleichgewicht stellt, dadurch die Lernphase verlängert und die Sturzhäufigkeit erhöht.A second, also known embodiment of the type mentioned also uses a normal, or at most slightly widened ski of known type, but the two ski bindings are mounted in the middle region of the ski behind each other, so to speak directly on the longitudinal center axis of the ski and at a longitudinal distance from each other, which corresponds approximately to the average foot length of an adult person. Such a position and orientation of the bindings forces the rider into a permanent lunge position over the longitudinal central axis of the ski, which places high demands on balance, thereby prolonging the learning phase and increasing the fall frequency.

Der grösste Nachteil dieser Stellung mit Ausfall-Schritt aber besteht darin, dass sich die Beine des Fahrers immer in einer ausgeprägten Schrägfahrt Position befinden, was für das Schrägfahren am Hang und das Kurvenfahren in der einen Richtung zwar recht extrem, aber doch akzeptabel ist, in der entgegengesetzten Richtung aber unnatürlich und damit störend empfunden wird. Das kann zu frühzeitigen Ermüdungserscheinungen und damit zu Stürzen führen. Aus diesen Gründen wurde auch diese Form von Einbrett-Ski nie wirklich populär.The biggest disadvantage of this position with failure step, however, is that the driver's legs are always in a pronounced slant position, which is quite extreme for slanting on slopes and cornering in one direction, but acceptable the opposite direction but unnatural and thus distracting. This can lead to early fatigue and thus to falls. For these reasons, this form of single-board skis never really became popular.

Die dritte, ebenfalls seit Jahren bekannte Art von Einbrett Ski unterscheidet sich von den zuvor beschriebenen dadurch, dass das Brett extrem breit, ja mehr als doppelt so breit als ein traditioneller Ski ist. Dies ist darum notwendig, weil die Bindungen und damit die Schuhe in einem Winkel von bis zu 90° zur Längsmittelachse des Brettes positioniert sind, und dabei die Distanz der Bindungen voneinander so gross ist, dass sich der Fahrer in einer Grätschestellung befindet. Manchmal wird die Bindung für den hinteren Fuss sogar etwas gegen rückwärts gedreht eingestellt. Die Stellung ist ähnlich wie die des Rollbrettfahrers auf der Strasse oder des Surfbrett-Sportlers auf dem Wasser. Dies ist auch der Grund, weshalb dieser Einbrett Ski den Namen Snow Board erhalten hat.The third type of single-board ski, which has also been known for years, differs from the one described above in that the board is extremely wide, even more than twice as wide as a traditional ski. This is necessary because the bindings and thus the shoes are positioned at an angle of up to 90 ° to the longitudinal center axis of the board, while the distance of the bonds from each other is so large that the driver is in a position of stare. Sometimes the binding for the back foot is even set a bit backwards. The position is similar to that of the skater on the street or the surfboard athlete on the water. This is also the reason why this single board ski has been named Snow Board.

Weil die Füsse des Snow Boarders mit der Fahrtrichtung einen Winkel von bis zu 90° zur Fahrrichtung einschliessen, ist der Körper beim Schrägfahren am Hang in der einen Fahrtrichtung zum Hang hin gerichtet, in der anderen Fahrtrichtung aber talwärts gerichtet. Entsprechend unterschiedlich ist auch die Stellung des Körpers beim Kurvenfahren nach der einen oder der anderen Richtung. Diese starre, von der Fahrrichtung weggedrehte Schuh- und Beinstellung macht dem Anfänger grosse Schwierigkeiten und hat deshalb unzählige Stürze in der Lernphase zur Folge. Es handelt sich hier im Grunde um eine unnatürliche, oft unbequeme und daher häufig auch ermüdende Stellung des Fahrers auf dem Brett. Ein ganz wesentlicher Nachteil von Ausrichtung und Distanz der Bindungen und Schuhe auf dem Snow Board besteht darin, dass es technisch nur mit grossem Aufwand möglich ist, Sicherheitsbindungen hierfür anzubieten. Denn eine Lösung, bei der nur die eine Bindung den Schuh freigibt, wäre hier gefährlicher als starre, nicht auslösende Bindungen. Es müsste also dafür gesorgt werden, dass beide Schuhe gleichzeitig freigegeben werden, was nur unter Inkaufnahme eines beträchtlichen technischen Aufwandes möglich ist.Because the feet of the Snow Boarder with the direction of travel include an angle of up to 90 ° to the direction of travel, the body is directed when sloping on a slope in one direction to the slope, in the other direction but directed downhill. Correspondingly different is the position of the body when cornering in one direction or the other. This rigid, turned away from the direction of travel shoe and leg position makes the novice big trouble and therefore has countless crashes in the learning phase result. This is basically an unnatural, often uncomfortable and therefore often tiring position of the driver on the board. A major disadvantage of alignment and distance of the bindings and shoes on the Snow Board is that it is technically possible only with great effort to provide security bonds for this. Because a solution in which only one bond releases the shoe would be more dangerous here than rigid, non-triggering bonds. It would therefore have to ensure that both shoes are released at the same time, which is possible only at the cost of a considerable technical effort.

Eine befriedigende Sicherheitsbindung für das Snow Board gibt es deshalb bis heute nicht, obwohl diese Sportart schon über 20 Jahre alt und bis vor wenigen Jahren sehr populär war, insbesondere unter jüngeren Wintersportlern. Dass das Snow Boarding heute rückläufig ist, hängt sicher mit den erwähnten Nachteilen zusammen und ist nicht allein eine Folge von abflauendem Trend oder Sättigung.A satisfactory safety bond for the Snow Board is therefore still not there, although this sport was already over 20 years old and until a few years ago was very popular, especially among younger winter athletes. The fact that snow boarding is on the decline today is certainly related to the disadvantages mentioned above and is not just a consequence of a declining trend or saturation.

Die Aufgabe der vorliegenden Erfindung ist es, neues Ski Sportgerät anzugeben, welches die Vorteile der genannten Arten immer noch anbietet, die Nachteile aber ganz oder weitestgehend eliminiert. Dieses Sportgerät soll in einer Ausführung zum Skifahren auf Schnee geeignet sein, in einer alternativen Ausführung zum Wasserskifahren. Es soll insbesondere Änderungen der Fuss-Stellung auf einem Monoski während der Fahrt ermöglichen, und in gewissen Varianten auch die Verschwenkung der Füsse weg von der Fahrtrichtung, sowie auch den Spurabstand der Füsse variierbar gestalten. Dabei soll das Ski-Sportgerät auch Sicherheitsaspekten Rechnung tragen, und eine Loslösung beim Auftreten grosser Kräfte sowohl beide Füsse gleichzeitig aus der Bindung wie auch einen Fuss einzeln von der Bindung freigeben können, wenn derselben übermässigen Kräften ausgesetzt wird. DE 103 05 536 A1 wie auch DE 197 45 226 A1 zeigen je einen Monoski oder ein Snowboard, auf dem die Bindungen gegengleich längsverschiebbar geführt sind. Die Bindungen sind seitlich aber immer gleich weit voneinander beabstandet und also einzig in der Länge verschiebbar, wobei die Bewegungen der beiden Bindungen mechanisch gekoppelt sind, sodass gegengleiche Bewegungen erzwungen werden. DE 101 11 093 A1 zeigt eine Lösung mit Bindungen auf einem Snowboard, die längs eines Kreisabschnittes mit verhältnismässig grossem Radius von fast der Länge des Snowboards verschiebbar sind. Jede Bindung ist auf einem Laufschlitten befestigt, der fahrbar auf einer fest eingebauten Laufschiene freigleitend verschiebbar ist. Die vorderen und hinteren Enden der beiden Laufschienen überschneiden sich. Die Bindungen verlaufen daher je nach Verschiebeposition schiefwinklig zur Längsrichtung des Snowboards. Die Snowboard-Bindung gemäss DE 197 10 436 A1 ist parallel zur Längsachse des Snowboards längsverschiebbar, wobei die Bewegungen über eine Zwangsführung geführt sein können, sodass sie in Abhängigkeit voneinander verschiebbar sind. Der seitliche Abstand der beiden Bindungen bleibt jedoch unveränderbar. Es geht einzig um eine Verschiebung in Längsrichtung auf dem Snowboard. In WO 2006/125401 ist ein Snowboard mit Besegelung und einer Bindung gezeigt, welche die Möglichkeit einer Rotation um die vertikale Achse bietet. Die Bindung ist hierfür auf einer schwenkbaren Plattform angeordnet, mit welcher sie fest verbunden ist, und welche eine regelbare Drehung um ihre vertikale Achse gemeinsam mit der Bindung ermöglicht, mit einer Möglichkeit der Bremsung ihrer Rotationsbewegung. Keine der vorgenannten Lösungen offeriert die Möglichkeit einer gegengleichen Bewegung der Bindungsplatten als Ränder eines Parallelogramms, sodass der seitliche Abstand der Bindungsplatten variiert wird. Nur bei einer solchen Lösung ist die Spurbreite der Füsse bei Geradeausfahrt und Mittelstellung der Bindungen maximal, sodass die Bindungsplatten den Monoski seitlich überragen. Der Monoskifahrer kann dadurch eine sehr stabile Haltung einnehmen, steht in Fahrrichtung und kann für Schussfahrten eine ganz normale Hockestellung einnehmen, was mit herkömmlichen Monoskis wegen der schmalen Spur der Fuss-Stellung schwierig wenn nicht gar unmöglich ist. Für die Kurvenfahrt hingegen können die Bindungen gegengleich in Längsrichtung des Monoskis verschoben werden, indem der Fahrer einen Ausfallschritt macht und einen Fuss voranstellt. Dabei nimmt infolge der erfindungsgemässen Parallelogramm-Anordnung der Abstand der Bindungsplatten in der Breite wesentlich ab, sodass die Spurbreite der Füsse reduziert wird, und die äusseren Ränder der Bindungsplatten innerhalb der Breite des Monoskis verlaufen. Das ist vor allem dann entscheidend, wenn das Gelände steil ist oder bei starker Schräglage in der Kurve: Es wird vermieden, dass der Hang-nähere oder Bogen-innere Schuh die Unterlage berührt. In Schräg- oder Kurvenfahrt liegt nur eine einzelne Kante auf und es ist es wichtig, dass sich der belastete Fuss über dieser Kante befindet. Erneut zeigt sich hier, wie wertvoll der Wechsel von der schmalen zu der breiten Position und umgekehrt ist. Die beanspruchte Konstruktion ist besonders einfach und robust, sehr reibungsarm beim Verändern der Fuss-Stellung, und die Konstruktion ist unempfindlich für Schnee, Eis oder Schmutz. Die Veränderbarkeit der Spurbreite beim Ausführen von Ausfallschritten macht das Fahrerlebnis abwechslungsreicher und weniger ermüdend als mit quasi "betonierter" Spurbreite der Füsse.The object of the present invention is to provide new ski sports equipment, which still offers the advantages of these types, but completely or largely eliminates the disadvantages. This sports equipment is to be suitable in one embodiment for skiing on snow, in an alternative embodiment for water skiing. It should in particular allow changes in the foot position on a monoski while driving, and in certain variants, the pivoting of the feet away from the direction of travel, as well as the track spacing of the feet make it variable. The ski sports equipment should also take into account safety aspects, and a detachment when large forces occur, both feet simultaneously from the bond as well as a foot can release individually from the bond when the same is exposed to excessive forces. DE 103 05 536 A1 as well as DE 197 45 226 A1 show each a monoski or a snowboard on which the bindings are guided against each other longitudinally displaceable. The bonds are laterally but always equidistant from each other and so only in length displaced, the movements of the two bonds are mechanically coupled, so counteracting movements are enforced. DE 101 11 093 A1 shows a solution with bindings on a snowboard, which are displaceable along a circular section with a relatively large radius of almost the length of the snowboard. Each binding is mounted on a carriage, which is mobile on a fixed running rail sliding freely. The front and rear ends of the two rails overlap. The bindings therefore run obliquely to the longitudinal direction of the snowboard, depending on the displacement position. The snowboard binding according to DE 197 10 436 A1 is longitudinally displaceable parallel to the longitudinal axis of the snowboard, wherein the movements can be guided via a positive guide, so that they are displaced in dependence on each other. The lateral distance of the two bonds, however, remains unchangeable . It's all about a shift in the longitudinal direction on the snowboard. In WO 2006/125401 a snowboard is shown with sail and a binding, which offers the possibility of rotation about the vertical axis . The binding is for this purpose on a swivel Platform arranged, with which it is firmly connected, and which allows a controllable rotation about its vertical axis together with the binding, with a possibility of braking their rotational movement. None of the aforementioned solutions offers the possibility of an equivalent movement of the binding plates as edges of a parallelogram, so that the lateral distance of the binding plates is varied. Only with such a solution, the track width of the feet when driving straight and center position of the bindings is maximum, so that the binding plates project beyond the monoski side. The Monoskifahrer can thereby take a very stable posture, stands in the direction of travel and can take a normal squatting position for firing, which is difficult if not impossible with conventional Monoskis because of the narrow track of the foot position. For cornering, however, the bindings can be shifted in the same direction in the longitudinal direction of the Monoskis by the driver makes a lunge and precedes a foot. As a result of the inventive parallelogram arrangement, the spacing of the binding plates decreases substantially in width, so that the track width of the feet is reduced , and the outer edges of the binding plates run within the width of the monoski. This is especially important if the terrain is steep or if there is a steep incline in the curve: it prevents the slope-closer or bow-inner shoe from touching the surface. When cornering or cornering, there is only a single edge and it is important that the loaded foot is over this edge . Once again it shows how valuable the change from the narrow to the wide position and vice versa. The claimed construction is particularly simple and robust, very low friction when changing the foot position, and the construction is resistant to snow, ice or dirt. The variability of the track width when performing lunges makes the driving experience more varied and less tiring than with virtually "concreted" track width of the feet.

Die Aufgabe wird gelöst von einem Monoski, in dessen mittlerem Bereich zwei Skibindungssysteme mit je einer Bindungsplatte für je einen Schuh oder Fuss angeordnet sind, wobei die Bindungsplatten auf dem Monoski durch eine Kopplung gegengleich längsverschiebbar gelagert sind, und der sich durch die Merkmale gemäss Patentanspruch 1 auszeichnet.The object is achieved by a monoski, in the central region of two ski binding systems, each with a binding plate for each shoe or foot are arranged, the binding plates are mounted on the monoski by a coupling gegengleich longitudinally displaceable, and by the features according to claim 1 distinguished.

Anhand der Zeichnungen werden verschiedene Ausführungen dieses Monoskis mit einer Vielzahl von verschiedenen Lösungen für die Bindungssysteme als Beispiele gezeigt und in der nachfolgenden Beschreibung im Einzelnen beschrieben und ihre Funktionen werden erläutert.Based on the drawings, various designs of this monoski with a variety of different solutions for the binding systems as examples are shown and described in detail in the following description and their functions will be explained.

Grundsätzlich wird die Erfindung mit einem relativ breiten Brett realisiert, ähnlich dem bekannten Snow Board, in dessen mittlerem Bereich ein Sockel in Form einer Bindungsplattform für die Bindungen über eine besondere Halterung mit dem Monoski derart verbunden ist, dass sich der ganze Sockel beim Sturz vom Monoski trennen kann. Bei der erwähnten Halterung handelt es sich also um eine Sicherheitsvorrichtung, deren Festhalte- resp. Auslösekraft einstellbar ist wie bei einer Sicherheits-Skibindung bekannter Art. Diese Bindungsplattform ist vorzugsweise im mittleren Bereich ihrer Unterseite mittels einer mit dem Ski fest verbundenen Scheibe drehbar aber nach oben lösbar gelagert, wie dies von bestimmten Sicherheits-Skibindungen, insbesondere Plattenbindungen, bereits bekannt ist.Basically, the invention is realized with a relatively wide board, similar to the known snowboard, in the central region of a base in the form of a binding platform for the bonds on a special mount with the monoski is connected in such a way that the whole base can be separated from the monoski during the fall. In the above-mentioned holder is therefore a safety device whose holding respectively resp. Triggering force is adjustable as in a safety ski binding known type. This binding platform is preferably in the central region of its underside by means of a firmly attached to the ski disc rotatable but releasably mounted upwards, as is already known from certain safety ski bindings, especially plate bindings ,

Jede der zwei Bindungen besteht aus einer eigenen Bindungsplatte, welche etwa die Länge des Schuhs hat, und einer an dieser jeweiligen Bindungsplatte befestigten Halterung bekannter Art für die Schuhspitze und einer ebenfalls an der Platte befestigten Halterung bekannter Art für den Schuhabsatz. Die zwei Bindungsplatten sind unabhängig voneinander so auf der Oberseite der Bindungsplattform gelagert, dass ihre Position vom Fahrer während der Fahrt verändert werden kann. In der Grundposition befinden sich die beiden Bindungen bzw. Schuhe symmetrisch zur Längs Mittelachse des Skis nebeneinander auf gleicher Höhe (Falllinien Fahrt). Für die Traversenfahrt und das Kurvenfahren kann der Fahrer den dem Hang näheren Schuh, den sogenannten Innenschuh mitsamt der Bindungsplatte leicht vorschieben und damit die für das normale Skifahren typische, bequeme und auch natürliche Schrägfahrtstellung einnehmen. Auch beim Kurvenfahren kann der bogeninnere Schuh leicht vorgeschoben werden. Dieser Positionswechsel gewährleistet ein lockeres und damit ermüdungsfreies, spassbetontes Fahren auf diesem Monoski. Die Lernphase ist wesentlich kürzer als bei den genannten, bereits bekannten Geräten, die Ansprüche an das Gleichgewicht sind weniger hoch. Dies bedeutet verminderte Sturzhäufigkeit und damit geringeres Verletzungsrisiko, was die Motivation, mit diesem Monoski Sport zu betreiben, wesentlich steigern wird.Each of the two bindings consists of a separate binding plate, which has approximately the length of the shoe, and a holder of known type for the toe fastened to this respective binding plate and a shoe heel of known type, also fastened to the plate. The two binding plates are independently mounted on top of the binding platform so that their position can be changed by the driver while driving. In the basic position, the two bindings or shoes are located symmetrically to the longitudinal center axis of the ski next to each other at the same height (fall line ride). For the truss ride and cornering, the driver can easily advance the shoe closer to the slope, the so-called inner shoe together with the binding plate and thus take the typical for normal skiing, comfortable and also natural inclined position. Even when cornering the bow inner shoe can be easily advanced. This change of position ensures a relaxed and thus fatigue-free, fun-driven driving on this monoski. The learning phase is much shorter than the mentioned, already known devices, the demands on the balance are less high. This means reduced fall frequency and thus lower risk of injury, which will significantly increase the motivation to operate with this Monoski Sport.

Die besondere Lagerung der Bindungsplatten kann technisch auf verschiedene Arten bewerkstelligt werden. Es wird erwartet, dass sich Lösungen besonders gut bewähren werden, bei denen das Verschieben der einen Bindungsplatte und das der andern gekoppelt sind, beispielsweise dergestalt, dass das Vorschieben der einen Bindungsplatte zwangsläufig ein Rückwärtsverschieben der anderen Platte zur Folge hat. Eine einfachste Lösung besteht darin, die eine Platte fest mit dem Sockel zu verbinden und nur die andere längsverschiebbar zu lagern. In diesem Falle muss eine Längsverschiebung der beweglichen in Bezug auf die starre Platte sowohl Richtung Skispitze als auch Richtung Skiende gewährleistet sein. Dabei kann entweder die linke Bindungsplatte oder die rechte Bindungsplatte stationär bleiben, je nach Wahl.The special storage of the binding plates can be accomplished technically in various ways. It is expected that solutions will be particularly well proven in which the displacement of one binding plate and the other are coupled, for example, such that the advancement of one binding plate inevitably results in a backward displacement of the other plate. A simplest solution is to connect one plate firmly to the base and to store only the other longitudinally displaceable. In this case, a longitudinal displacement of the movable relative to the rigid plate both direction Ski tip as well as direction ski end be guaranteed. Either the left binding plate or the right binding plate can remain stationary, depending on the choice.

In Figur 1 ist eine Realisierungsmöglichkeit gemäß der Erfindung aufgezeigt. Hier sind zwei Schwenkplatten 180a, 181b hintereinander auf der Bindungsplattform 110 angeordnet, und zwar über je einen Drehbolzen 181a, 181b. Damit sind diese beiden Schwenkplatten 180a, 180b um diese Drehbolzen horizontal verschwenkbar. Auf beiden seitlichen Enden sind Ohren ausgeformt, die einen Schwenknocken 123a-d für die Bindungsplatten 120a,120b aufweisen. Jede Bindungsplatte 120a,120b ist dann über zwei solche Schwenknocken 123a,123c und 123b,123d auf den Schwenkplatten 180a, 180b gehalten. Die Zentren der Schwenknocken bilden somit ein Parallelogramm, welches um die Drehbolzen 181a, 181b verschwenkbar ist. Dabei führen die Bindungsplatten gegengleiche Bewegungen aus. Sie verbleiben stets in einer parallelen Richtung zum Monoski, können aber nach vorne und hinten geschoben werden, unter gleichzeitiger paralleler Annäherung an sich. Die Bindung ist in Figur 2 von der Seite her mit eingesetztem Skischuh gezeigt. Die möglichen Stellungen sind in den Figuren 4 bis 6 dargestellt. Wenn die Füsse nebeneinander gehalten werden, also ohne Ausfallschritt, so überragen die Bindungsplatten 120a,120b den Monoski seitlich, wie aus Figur 1 ersichtlich. Je stärker der Ausfallschritt - ob nach links oder rechts - umso schmaler wird die Spur, das heisst der Abstand zwischen den beiden Bindungsplatten bzw. Füssen des Fahrers. In der Stellung mit maximalem Ausfallschritt wie in Figuren 5 und 6 gezeigt sieht man, dass die Bindungsplatten nun über dem Monoski 100 liegen und ihn also seitlich nicht mehr überragen.In FIG. 1 an embodiment according to the invention is shown. Here are two pivot plates 180a, 181b arranged one behind the other on the binding platform 110, via a respective pivot pin 181a, 181b. Thus, these two pivot plates 180a, 180b are pivotable horizontally about these pivot pins. On both lateral ends, ears are formed having a pivot cam 123a-d for the binding plates 120a, 120b. Each binding plate 120a, 120b is then held on the pivoting plates 180a, 180b via two such pivoting cams 123a, 123c and 123b, 123d. The centers of the pivot cams thus form a parallelogram, which is pivotable about the pivot pins 181a, 181b. The binding plates perform similar movements. They always remain in a parallel direction to the monoski, but can be pushed forwards and backwards, while at the same time approaching each other in parallel. The binding is in FIG. 2 shown from the side with inserted ski boot. The possible positions are in the FIGS. 4 to 6 shown. If the feet are held side by side, without lunge, the binding plates 120a, 120b project laterally beyond the monoski FIG. 1 seen. The stronger the lunge - whether to the left or right - the narrower the track, that is the distance between the two binding plates or feet of the driver. In the position with maximum lunge as in FIGS. 5 and 6 shown you can see that the binding plates are now above the monoski 100 and therefore no longer project beyond it.

Es ist möglich und sinnvoll, bei all diesen Ausführungsform Anschläge vorzusehen oder aber Widerstände, gegen welche die Verdrehung der Bindungsplatten bzw. der Schuhe und der Schwenkplatten entgegenwirken. Genau so kann es unter Umständen sinnvoll sein, die Schiebe- und Drehbewegungen aller hiervor genannten und in den Figuren dargestellten Ausführungsformen mit Widerständen, z.B. Zug- oder Druckfedern zusammenwirken zu lassen.It is possible and useful to provide attacks in all these embodiments attacks or resistors against which counteract the rotation of the binding plates and the shoes and the pivot plates. In exactly the same way, it may make sense to use the sliding and rotating movements of all the embodiments mentioned above and shown in the figures with resistors, e.g. Tension or compression springs interact.

Die weiter vorne beschriebenen Bindungen können natürlich auch als Schlaufen ausgebildet werden, aus denen sich die Füsse während der Fahrt lösen können. Es kann zudem vorteilhaft sein, die Bindungsplatten so auf der Plattform zu lagern, dass sie sowohl in Längsrichtung verschoben als auch um eine lotrecht zur Boardfläche stehende Achse gedreht werden können, entweder innerhalb eines begrenzten Winkels oder rundum bis zu 360 Grad. Es kann auch sinnvoll sein, technisch dafür zu sorgen, dass die Bewegungen der Bindungsplatten und das Zusammenwirken dieser Bewegungen entgegen Federkraft erfolgt, in dem Federn beispielsweise aus Metall, Kunststoff oder Gummi eingebaut werden.Of course, the bindings described above can also be formed as loops, from which the feet can be released while driving. It may also be advantageous to mount the binding plates on the platform so as to be displaced both longitudinally and perpendicular to the board surface standing axis can be rotated, either within a limited angle or all around up to 360 degrees. It may also be useful to technically ensure that the movements of the binding plates and the interaction of these movements takes place against spring force, are installed in the springs, for example, metal, plastic or rubber.

Mittels Anschlägen und Steuerkurven kann erreicht werden, dass die Bewegungen besonders vorteilhaften Abläufen und Wegen folgen. Von besonderer Bedeutung für das zuverlässige Funktionieren des erfindungsgemässen Sportgerätes ist eine Ausführungsform, bei der die Lagerung und Koppelung der Platten und ihre Bewegungen hauptsächlich mittels Gelenk- und Hebelsystemen bewerkstelligt werden. Dadurch können Funktionsstörungen durch Einflüsse von Schnee, Eis, Wasser, Schmutz und Sand, die je nach Anwendung der Erfindung für ein Schnee-, Land- oder Wasser-Sportgerät unterschiedlich stark sein können, weitestgehend eliminiert werden.By means of stops and cams can be achieved that the movements follow particularly advantageous processes and ways. Of particular importance for the reliable functioning of the sports equipment according to the invention is an embodiment in which the storage and coupling of the plates and their movements are accomplished mainly by means of joint and lever systems. As a result, dysfunctions due to influences of snow, ice, water, dirt and sand, which can vary depending on the application of the invention for a snow, land or water sports equipment, can be largely eliminated.

Bei einigen der beschriebenen Ausführungen ist als Vorteil zu sehen, dass die Bindungsplatten so auf dem Sockel gelagert sind, dass in der Grundposition ein normaler seitlicher Abstand der Schuhe voneinander besteht und damit eine natürliche, lockere Bein- und Körperstellung für die Falllinienfahrt eingenommen werden kann, und dass sich beim Verschieben der Platten in Längsrichtung der seitliche Abstand der Schuhe voneinander reduziert, d.h., die Bindungsplatten sich leicht der Längsmittellinie des Skis nähern. Dies hat den Vorteil, dass die Aussenseite des bogeninneren Schuhs in der Kurve nicht mehr vorsteht gegenüber der Skikante, wodurch die Gefahr, bei extremer Schräglage in der Kurve mit dem Schuh den Schnee zu berühren und dann wegzurutschen, praktisch ausgeschaltet wird. In Anbetracht des Trends zu immer stärkerer Taillierung der Skis und Snowboards ist dies ein wichtiger Aspekt der hiervor erläuterten Funktionsweise der Bindungen. Denn der erfindungsgemässe Monoski soll diesem Trend völlig gerecht werden können. in diesem Zusammenhang wird erwartet, dass eine starke Taillierung beim erfindungsgemässen Monoski wesentlich weniger Gefahren hinsichtlich von Beinverletzungen verursachen wird als stark taillierte, normale Skis, sogenannte Carving Skis.In some of the described embodiments, it can be seen as an advantage that the binding plates are mounted on the pedestal such that in the basic position there is a normal lateral distance of the shoes from each other and thus a natural, loose leg and body position can be assumed for the fall-line ride, and that when the plates are displaced in the longitudinal direction, the lateral spacing of the shoes from each other is reduced, that is, the binding plates easily approach the longitudinal center line of the ski. This has the advantage that the outside of the bow inner shoe in the curve no longer protrudes from the ski edge, whereby the risk of extremely slanted in the curve with the shoe to touch the snow and then slide away, is virtually eliminated. In view of the trend towards ever-increasing waisting of skis and snowboards, this is an important aspect of the functioning of the bindings explained above. Because the monoski according to the invention should be able to fully meet this trend. In this context, it is expected that a strong sidecut in the monoski according to the invention will cause substantially fewer risks with regard to leg injuries than strongly fitted, normal skis, so-called carving skis.

Schliesslich ist auch daran gedacht, die Funktionsprinzipien des erfindungsgemässen Sportgerätes für die Verwendung als Wasserski einzusetzen, oder für ein Rollbrett bzw. Skateboard zur Benützung auf Hartbelagplätzen und Strassen, wobei dieselben Mechanismen für die bewegliche Lagerung der Bindungen auf solchen Geräten zum Einsatz kommen, sei es in Verbindung mit einer sich beim Sturz lösenden, oder einer fest mit dem Brett verbundenen Plattform.Finally, it is also intended to use the functional principles of the sports equipment according to the invention for use as waterski, or for a skateboard or skateboard for use on hard surfaces and roads, the same mechanisms are used for the movable mounting of the bindings on such devices, whether in connection with a fall-off, or a fixed platform connected to the board.

Insgesamt ist es ein erklärtes Ziel der vorliegenden Erfindung, das genussvolle Erlebnis des Fahrens mit stark taillierten Skis zu erhalten, ja noch zu steigern, das Verletzungsrisiko aber massiv zu reduzieren. Zum einen wird dies dadurch erreicht, dass die beim Fahren mit einem solchen Monoski auftretenden Kräfte immer von beiden Beinen gleichzeitig aufgenommen werden. Zum anderen wird die Unfallgefahr beim Sturz dadurch erheblich reduziert, dass beide Schuhe gleichzeitig mitsamt der Bindungsplattform vom Monoski getrennt werden.Overall, it is a stated aim of the present invention, the enjoyable experience of driving with highly waisted skis to get, yes even increase, but to reduce the risk of injury massively. On the one hand, this is achieved in that the forces occurring when driving with such a monoski are always absorbed by both legs simultaneously. On the other hand, the risk of accidents during the fall is significantly reduced by the fact that both shoes are simultaneously separated from the monoski together with the binding platform.
