Abstract
Description
Die Erfindung betrifft ein Wassersportgerät, das über die Wasseroberfläche rollen kann nach dem Oberbegriff des An spruches 1.The invention relates to a water sports device that over the Water surface can roll according to the generic term of the An saying 1.
Ein gattungsgemäßes Wassersportgerät wird in der EP-OS 01 29 103 beschrieben. Außerdem ist die Konstruktion eines Schaufel rades mit auftrieb- und vortriebbildenden Flächen aus der AT-PS 1 32 095 und die Anbringung einer lenkbaren Heckflosse aus der FR-PS 6 50 458 bekannt.A generic water sports device is described in EP-OS 01 29 103. In addition, the construction of a shovel wheels with lift and propulsion surfaces from the AT-PS 1 32 095 and the attachment of a steerable tail fin known from FR-PS 6 50 458.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsge mäßes Wassersportgerät so zu verbessern, daß der Reibungs widerstand verringert wird.The invention has for its object a genus moderate water sports equipment so that the friction resistance is reduced.
Diese Aufgabe wird bei einem gattungsgemäßen Wassersport gerät dadurch gelöst, daß die Schwimmkörper als zwei flügel artige Stabilisatoren ausgebildet sind, die an dem Stütz rahmen mittels eines Gelenks angebracht und um 3 Achsen be wegbar sind, wobei die flügelartigen Stabilisatoren vor dem Start als Schwimmer dienen und nach dem Start vom Benutzer manuell gegen den Wind zur Stabilisierung des Wassersport gerätes eingestellt werden können. Vorteilhafte Ausgestal tungen der Erfindung sind in den Unteransprüchen angegeben. So ist am Stützrahmen eine Heckflosse als Leitwerk fest oder manuell lenkbar angebracht. Den notwendigen Vortrieb und Auf trieb erzeugt ein Schaufelrad. Vorteilhaft weist jede Schau fel des Schaufelrades eine auftriebbildende Fläche und eine vortriebbildende Fläche auf. Die auftriebbildende Fläche greift in Bewegung im spitzen Winkel die Wasseroberfläche an, gleitet darüber und ist mindestens dreimal so groß wie die vortriebbildende Fläche, welche möglichst senkrecht in das Wasser eintaucht.This task is carried out in a generic water sport device solved in that the floating body as two wings Like stabilizers are formed on the support frame attached by means of a joint and be around 3 axes are movable, the wing-like stabilizers in front of Start as a float and after the start by the user manually against the wind to stabilize water sports device can be set. Advantageous design tions of the invention are specified in the subclaims. A tail fin is fixed to the support frame as a tail or attached manually steerable. The necessary propulsion and up drive produces a paddle wheel. Every show is advantageous fel of the paddle wheel a buoyant surface and a propulsive surface. The buoyant surface grips the surface of the water in motion at an acute angle on, glides over it and is at least three times as large as the propulsion-forming surface, which is as vertical as possible in the water dips.
Der Antrieb des Schaufelrades erfolgt über eine Kette mit Muskelkraft oder mit einem Motor.The paddle wheel is driven by a chain Muscle strength or with a motor.
In der Zeichnung ist die Erfindung anhand eines Ausführungs beispiels näher veranschaulicht, es zeigtIn the drawing, the invention is based on an embodiment exemplified in more detail, it shows
Fig. 1 eine Skizze des Wassersportgerätes mit einem ver größerten Detail des Schaufelrades, Fig. 1 is a sketch of the water sports equipment with a ver größerten detail of the blade wheel,
Fig. 2 eine Seitenansicht des sich in Fahrt befindlichen Wassersportgerätes,A side view of the water sports equipment is located in drive Fig. 2,
Fig. 3 eine Draufsicht auf das Wassersportgerät, Fig. 3 is a plan view of the water sports equipment,
Fig. 4 eine Seitenansicht des sich vor oder während des Starts befindlichen Wassersportgerätes. Fig. 4 is a side view of the water sport device located before or during the start.
Gemäß Fig. 1 weist das Schaufelrad 1 eine auftriebbildende Fläche 1 a und eine vortriebbildende Fläche 1 b auf.Referring to FIG. 1, the impeller 1 is a boost-forming surface 1 a and a propulsion-forming surface 1 b on.
Nach Fig. 2 + 3 weist das Wassersportgerät einen Stütz rahmen 4 auf, der den Motor 5 als Antrieb mit der Kette 7 beinhaltet und um die Achse 8 schwenkbar ist. Auf der Achse 8 ist ein Schaufelrad 1 drehbar gelagert. Am oberen Ende des Stützrahmens 4 sind flügelartige Stabilisatoren 2 mittels eines Gelenkes 6 befestigt, die um drei Achsen verschwenk bar sind. Hinten am Stützrahmen ist eine als Leitwerk aus gebildete Heckflosse 3 angebracht.According to Fig. 2 + 3, the water sports apparatus comprises a support frame 4, which includes the motor 5 as the drive with the chain 7 and is pivotable about the axis 8. A paddle wheel 1 is rotatably mounted on the axis 8 . At the upper end of the support frame 4 , wing-like stabilizers 2 are fastened by means of a joint 6 , which are pivotable about three axes. At the rear of the support frame there is a tail fin 3 formed as a tail unit.
In Fig. 4 befindet sich das Wassersportgerät vor oder während des Starts. Die in dieser Situation als Schwimmer wirkenden flügelartigen Stabilisatoren 2 und das schwimmfähige Schaufel rad 1 sorgen für genügend Auftrieb. Beim Start, nach Erreichen ausreichender Geschwindigkeit (Fig. 2) wird der Stützrahmen 4 nach oben geschwenkt und unterstützt durch positive Anstellung der flügelartigen Stabilisatoren gegenüber dem Fahrtwind. Die senkrecht in das Wasser ragenden vortriebbildenden Flächen 1 b des Schaufelrades 1 sorgen für eine schnelle Verzögerung beim Stoppen des Schaufelrades.In Fig. 4 the water sports device is before or during the start. The wing-like stabilizers 2 acting in this situation as a float and the buoyant blade wheel 1 ensure sufficient buoyancy. At the start, after sufficient speed has been reached ( FIG. 2), the support frame 4 is pivoted upwards and is supported by positive adjustment of the wing-like stabilizers to the headwind. The propulsion-forming surfaces 1 b of the impeller 1 projecting vertically into the water ensure a rapid deceleration when the impeller stops.
