Description

Die Erfindung betrifft ein Wasserfahrzeug mit zwei parallel und im Abstand zueinander angeordneten Surfbrettern, die mit Hilfe eines Rahmens miteinander verbunden sind.The invention relates to a watercraft with two in parallel and at a distance Surfboards arranged to each other, which are joined together with the help of a frame are connected.

Ein derartiges Wasserfahrzeug ist aus der DE 40 30 225 und aus der DE 42 43 752 bekannt.Such a watercraft is from DE 40 30 225 and from DE 42 43 752 known.

Die dort beschriebenen Wasserfahrzeuge haben jedoch den Nachteil, daß sie bei großen Geschwindigkeiten leicht anfangen, instabil zu werden, was einerseits das Fahrverhalten negativ beeinflußt und andererseits zu extremen Beanspruchungen des Rahmens führt.However, the watercraft described there have the disadvantage that they at high speeds easily start to become unstable, which is one thing Driving behavior negatively influenced and on the other hand to extreme loads of the frame.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gattungsgemäßes Wasserfahrzeug so weiter zu entwickeln, daß es auch bei großen Geschwindigkeiten gute Fahreigenschaften aufweist.The invention is therefore based on the object of a generic To develop the watercraft so that it can be used even with large Speeds has good driving characteristics.

Diese Aufgabe wird dadurch gelöst, daß bei einem gattungsgemäßen Wasserfahrzeug der Rahmen einen Hauptrahmen und eine Verbindungsstange aufweist, die jeweils mit den Surfbrettern und über in Fahrtrichtung liegende Schenkel miteinander verbunden sind, die zwei in Fahrtrichtung liegenden Schenkel des Rahmens flexible Elemente aufweisen und der Rahmen ein diagonal verspanntes Rechteck bildet. This object is achieved in that, in a generic watercraft, the frame has a main frame and a connecting rod, which are each connected to the surfboards and by legs lying in the direction of travel , the two legs of the frame lying in the direction of travel have flexible elements and the frame a diagonally braced rectangle.

Der so konstruierte Rahmen legt die am Rahmen angreifenden Kräfte der Wellen auf Teilbereiche des Rahmens um, was in einem geringeren Widerstand und somit einer höheren Endgeschwindigkeit resultiert.The frame constructed in this way sets the forces of the waves acting on the frame to parts of the frame around what results in less resistance and thus a higher top speed results.

Die bisher bekannten Surfgleiter besitzen starre, in Fahrtrichtung liegende Rahmenschenkel und führen zu einem starken Schaukeln des Wasserfahrzeugs bei schnellerer Fahrt. Im Gegensatz hierzu kann der erfindungsgemäße Rahmen so ausgebildet sein, daß er statisch starr nur die hinteren Fußschlaufen der Surfbretter und ggf. einen Außenbordmotor aufnimmt. An dem hinteren Rahmenteil werden dann nach vorne hin flexible Elemente angesetzt, die den Hauptrahmen mit den Verbindungköpfen rechts und links jeweils dynamisch verbinden. Die Verbindungsköpfe sind dann starr, leicht lösbar über die Sitzstange miteinander verbunden und diagonal mit den Eckpunkten des Hauptrahmens verspannt. Durch diese Anordnung können die Verbindungsköpfe einzeln, frei vertikal, dynamisch beweglich am Rahmen angesehen werden. Eine einseitig das Boot anhebende Welle hebt nun nur ein Brett und damit das Fahrzeug weniger an.The previously known surf gliders have rigid frame legs lying in the direction of travel and lead to a strong rocking of the watercraft when driving faster. In contrast, the frame according to the invention can be designed so that it statically rigid receives only the rear straps of surfboards and possibly an outboard motor. Flexible elements are then attached to the rear frame part towards the front, which dynamically connect the main frame with the connection heads on the right and left. The connecting heads are then rigid, easily detachably connected to one another via the perch and braced diagonally with the corner points of the main frame. With this arrangement, the connection heads can be viewed individually, freely vertically, dynamically movably on the frame. A shaft lifting the boat on one side only lifts one board and therefore the vehicle less.

Die diagonale Verspannung wird vorzugsweise durch sich kreuzende Seile vorgenommen. Alternativ oder zusätzlich hierzu kann die diagonale Verspannung jedoch auch von einem stärkeren rechteckigen Stoff aufgenommen werden. Dieser Stoff kann dann gleichzeitig auch als Sitzfläche dienen.The diagonal bracing is preferably done by crossing ropes performed. Alternatively or in addition, the diagonal bracing can be used but can also be absorbed by a stronger rectangular fabric. This Fabric can then also serve as a seat.

Vorteilhaft ist es, wenn die flexiblen Elemente elastisch sind. Obwohl die Verspannung und die Anordnung der flexiblen Verbindungsstücke schon für eine gewisse Elastizität des Rahmens sorgt, ist es vorteilhaft, wenn die flexiblen Elemente elastisch ausgebildet sind. It is advantageous if the flexible elements are elastic. Although the Bracing and the arrangement of the flexible connectors for one ensures some elasticity of the frame, it is advantageous if the flexible Elements are elastic.

Der Transport des Wasserfahrzeugs wird stark vereinfacht, wenn der Rahmen im Bereich der flexiblen Elemente teilbar ist. Durch das Teilen des Rahmens im Bereich der flexiblen Elemente entstehen zwei starre Rahmenteile, die durch Einstecken der flexiblen Elemente und die diagonale Verspannung fest miteinander zu verbinden sind.The transport of the watercraft is greatly simplified if the frame in the Area of flexible elements is divisible. By dividing the frame in the area The flexible elements create two rigid frame parts, which are inserted by inserting the flexible elements and the diagonal bracing are.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Wasserfahrzeugs sieht vor, daß der Rahmen über je eine Mastfußaufnahme und Fußschlaufen der Surfbretter leicht lösbar mit den Surfbrettern verbunden ist. Dies ermöglicht es, standardmäßig hergestellte Surbretter zu verwenden, die sowohl als erfindungsgemäßes Wasserfahrzeug als auch als Surfbretter ohne größere Umbaumaßnahmen weiter verwendet werden können.An advantageous embodiment of the watercraft according to the invention provides that the frame has a mast foot mount and foot straps of the surfboards is easily detachably connected to the surfboards. This makes it possible by default to use manufactured surfboards, both as inventive Watercraft as well as surfboards without major renovations can be used.

Hervorragende Fahreigenschaften ergeben sich, wenn das Wasserfahrzeug eine von Hand betätigbare Einrichtung zur Richtungssteuerung aufweist, über die die Surfbretter mittels der an ihnen befindlichen Fußschlaufen über die daran leicht lösbar befestigten Auflageelemente, die am Rahmen schwenkbar befestigt sind, der Richtungssteuerung entgegengesetzt, angeschwenkt werden. Das Schwenken der Surrbretter bei einer Kurvenfahrt ermöglicht beispielsweise deutlich engere Kurven, da die Surfbretter zum Teil die Funktion eines Kieles oder Schwertes übernehmen.Excellent driving characteristics result when the watercraft is one of Hand-operated device for direction control, via which the Surfboards by means of the foot straps on them over the lightly releasably attached support elements which are pivotally attached to the frame, the Direction control opposite, can be swiveled. The panning of the Surr boards when cornering, for example, enable significantly tighter curves, because the surfboards partly function as a keel or sword.

Vorteilhaft ist es, wenn der Rahmen Steuerungseinrichtungen aufweist. Am Rahmen können beispielsweise Einrichtungen zur Änderung der Fahrtrichtung, Getriebesteuerungen oder Geschwindigkeitssteuereinrichtungen vorgesehen sein. Vorzugsweise wird an einem die Surfbretter verbindenden Rahmenholm eine Lenkeinrichtung angebracht, während die Übersetzungs- und Geschwindigkeitsregelungseinrichtungen an den in Fahrtrichtung liegenden Schenkeln des Rahmens angeordnet sind.It is advantageous if the frame has control devices. On the frame can, for example, devices for changing the direction of travel, Transmission controls or speed control devices can be provided. Preferably, a frame spar connecting the surfboards is a Steering device attached while the translation and speed control devices on the legs of the frame in the direction of travel are arranged.

Darüber hinaus ist vorgesehen, daß am Rahmen Befestigungseinrichtungen angeordnet sind. Diese Befestigungseinrichtungen können unterschiedlichsten Zwecken, wie beispielsweise der Befestigung von Gepäckbehältern, Reservetanks oder ähnlichem dienen.In addition, it is provided that fastening devices on the frame are arranged. These fastening devices can be very different Purposes, such as securing luggage, reserve tanks or the like.

Die Befestigungseinrichtungen können auch dazu dienen, eine Besegelung am Wasserfahrzeug anzubringen. Vorzugsweise wird mindestens eine im Surfsport bekannte Mastfußhalterung am Rahmen befestigt, um ein oder mehrere Segel am Wasserfahrzeug anzubringen. Darüber hinaus kann jedoch auch ein feststehender Mast am Rahmen befestigt und dort verankert werden.The fasteners can also be used to sail on Attach watercraft. At least one is preferred in surfing known mast foot bracket attached to the frame to one or more sails on Attach watercraft. In addition, however, a fixed one Mast attached to the frame and anchored there.

Besonders vorteilhaft ist es, wenn der Rahmen Einrichtungen zum Befestigen von Schwertern aufweist. Diese Schwerter sind vorzugsweise aus dem Surfbereich bekannte Finnen, die etwa in der Mitte des Rahmens angeordnet werden sollten.It when the frame devices for attaching is particularly advantageous Has swords. These swords are preferably from the surfing area known fins, which should be placed approximately in the middle of the frame.

Insbesondere bei hohen Geschwindigkeiten ist es von Vorteil, wenn das in Fahrtrichtung vorne liegende Rahmenteil einen Spoiler aufweist. Ein derartiger Spoiler sorgt beispielsweise bei Fahrten über 50 km/h dafür, daß der Bug des Wasserfahrzeugs heruntergedrückt wird. Der Geradeauslauf bei hohen Geschwindigkeiten kann auch durch aufrechte Leitflossen, die in die Luft ragen, unterstützt werden.Especially at high speeds, it is an advantage if the in Front part of the frame has a spoiler. Such one Spoiler, for example, ensures that the bow of the Watercraft is pressed down. Straight ahead at high Velocities can also be increased by upright guide fins that protrude into the air get supported.

Ein einfacher, stabiler Rahmenaufbau wird dadurch erreicht, daß die in Fahrtrichtung liegenden Schenkel des Rahmens an sich gegenüberliegenden Enden, vorzugsweise an den in Fahrtrichtung hinteren Enden, mit einem Seil verbunden sind. Gerade das Anbringen eines Seils im hinteren Bereich sorgt zusätzlich dafür, daß ein am Rahmen befestigter Motor geschützt wird.A simple, stable frame structure is achieved in that the in Leg of the frame lying at the direction of travel at opposite ends, preferably connected at the rear ends in the direction of travel with a rope are. Attaching a rope in the rear area also ensures that a motor attached to the frame is protected.
