Description

Die Erfindung betrifft ein Wasserfahrzeug insbesondere zur Verwendung durch Einzelpersonen mit einem Auftriebskörper, einem Tretantrieb und einem Sitz.The invention relates to a watercraft, in particular for use by individuals with a buoyancy body, a pedal drive and a seat.

Wasserfahrzeuge der gattungsgemäßen Art dienen in erster Linie der zu Zwecken der Freizeitgestaltung ausgeübten Fortbewegung auf dem Wasser. Als solche sind sie - bisher vor allem unter dem Namen "Tretboote" - weithin bekannt. Im Gegensatz zu Ruderbooten bieten Wasserfahrzeuge der gattungsgemäßen Art die Möglichkeit, die im Vergleich zu der Arm- und Rückenmuskulatur in der Regel wesentlich höhere Kraft der Beinmuskeln zur Fortbewegung auf dem Wasser auszunutzen. Insofern dürften sie grundsätzlich ergonomisch günstiger sein, als Ruder- und/oder Paddelboote, also die mögliche Leistungsfähigkeit des menschlichen Körpers besser ausnutzen als jene. Bisher ist es allerdings nicht gelungen, Wasserfahrzeuge der gattungsgemäßen Art so zu gestalten, daß sie ohne weitere Schwierigkeiten etwa in PKW zu Wasserflächen mitgeführt werden können. Die bisher bekannten gattungsgemäßen Wasserfahrzeuge sind allesamt für einen derartigen Transport nur bedingt geeignet, da zu sperrig und nicht zerlegbar.Watercraft of the generic type serve primarily for locomotion on the water for leisure purposes. As such, they are widely known - above all under the name "pedal boats". In contrast to rowing boats, watercraft of the generic type offer the possibility of using the leg muscles' strength, which is generally much higher than that of the arm and back muscles, for locomotion on the water. In this respect, they should in principle be ergonomically cheaper than rowing and / or paddle boats, i.e. make better use of the potential performance of the human body than that. So far, however, it has not been possible to design watercraft of the generic type in such a way that they can be carried to water surfaces without further difficulties, for example in cars. The previously known generic watercraft are all only suitable for such transport to a limited extent because they are too bulky and cannot be dismantled.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Wasserfahrzeug mit Tretantrieb zu schaffen, das bei einfachem Aufbau den Vorteil der leichten Zerlegbarkeit und damit die Möglichkeit des Transports mit normalem PKW bietet.The invention is therefore based on the object of providing a watercraft with a pedal drive which, with a simple construction, offers the advantage of easy dismantling and thus the possibility of transporting it with a normal car.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Auftriebskörper zwei Rümpfe, vorzugsweise aus Leichtmetallen oder Kunststoff sind, die mittels eines zerlegbaren Gestänges lösbar untereinander so verbunden sind, daß ihre Längsachsen etwa parallel zueinander ausgerichtet sind. Der damit erzielte Vorteil besteht darin, daß durch die beiden Rümpfe nach dem bekannten Katamaran-Prinzip eine hohe Stabilität des Wasserfahrzeugs erreicht wird, das Fahrzeug aber selbst auf Transportmaße zerlegt werden kann, die einen PKW-Transport gestatten.This object is achieved in that the buoyancy bodies are two hulls, preferably made of light metals or plastic, which are detachably connected to one another by means of a collapsible linkage such that their longitudinal axes are aligned approximately parallel to one another. The advantage achieved in this way is that the two hulls, based on the known catamaran principle, achieve a high stability of the watercraft, but the vehicle itself can be disassembled to transport dimensions that permit transport by car.

In einer Weiterbildung der Erfindung ist vorgesehen, daß das Gestänge aus vorzugsweise vier Traversen besteht, die jeweils von einem Rumpf ausgehen umd in einem Rahmenkopf zusammentreffen. Diese Anordnung bietet neben einem einfachen Aufbau vor allem den Vorteil des schnellen Einsetzens und Lösens der Gestängeverbindungen, die allesamt in einem zentralen Punkt, dem Rahmenkopf, zusammenlaufen.In a further development of the invention it is provided that the linkage preferably consists of four crossbeams, each starting from a fuselage and meeting in a frame head. In addition to a simple construction, this arrangement above all offers the advantage of quick insertion and release of the linkage connections, which all converge at a central point, the frame head.

In einer Fortbildung der Erfindung wird weiterhin vorgeschlagen, daß die Traversen aus der durch die Oberseite der Rümpfe beschriebenen Ebene nach oben herausragen.
Der Vorteil dieser pyramidenförmigen Anordnung besteht nun insbesondere darin, daß der Rahmenkopf so eine Lage vergleichsweise hoch über der Wasserfläche einnehmen kann. Der Rahmenkopf eignet sich daher bei dieser Anordnung zur Aufnahme eines Sitzes. Die Steuerung und Änderung der Fahrtrichtung wird besonders einfach dann, wenn der Sitz in größerer Höhe über der Wasserfläche angeordnet ist, so daß durch Gewichtsverlagerung einer der beiden Rümpfe zu tieferem Eintauchen gebracht werden kann. Da sich dadurch der Wasserwiderstand dieses Rumpfes erhöht, ist ein Steuern durch bloße Gewichtsverlagerung möglich.In a further development of the invention it is further proposed that the trusses from the plane described by the top of the hulls protrude upwards.
The advantage of this pyramid-shaped arrangement is in particular that the frame head can take such a position comparatively high above the water surface. The frame head is therefore suitable in this arrangement for receiving a seat. Controlling and changing the direction of travel is particularly easy when the seat is located at a greater height above the water surface, so that one of the two hulls can be immersed deeper by shifting the weight. Since this increases the water resistance of this hull, control is possible by simply shifting your weight.

In einer Fortbildung der Erfindung ist außerdem bevorzugt, daß die Verbindungen zwischen Traversen und Rümpfen und/oder zwischen Traversen und Rahmenkopf lösbare Verbindungen, insbesondere Schraub-, Steck- oder Klemmverbindungen sind. Diese Ausführung der notwendigen Verbindungen bietet vor allem den Vorteil der raschen Zerlegbarkeit des gesamten Wasserfahrzeugs. Bei geeigneter Ausführung der fraglichen Verbindungen wird eine Lösung ohne besonderes Werkzeug möglich sein. Das erfindungsgemäße Wasserfahrzeug kann daher schnell und unschwer demontiert und etwa auf oder in einem PKW zu einer geeigneten Wasserfläche mitgeführt werden.In a further development of the invention, it is also preferred that the connections between cross members and hulls and / or between cross members and frame head are detachable connections, in particular screw, plug or clamp connections. This design of the necessary connections offers the advantage of the fact that the entire watercraft can be dismantled quickly. With a suitable execution of the connections in question, a solution without special tools will be possible. The watercraft according to the invention can therefore be dismantled quickly and easily and carried along to or in a car to a suitable water surface.

Bevorzugt ist als Sitz an der Oberseite des Rahmenkopfes einen Sattel zu befestigen. Diese Anordnung bietet den Vorteil der stabilen Befestigung des Sitzes, der sich an dem Punkt abstützt, an dem alle auf das Wasserfahrzeug einwirkenden Kräfte zusammentreffen. Zudem wird sich der Rahmenkopf wegen seiner konstruktionsbedingten zentralen Lage in der Regel etwa vertikal über dem Fahrzeugschwerpunkt befinden. Die Ausführung des Sitzes als Sattel bietet zudem den Vorteil einer aufrechten und ermüdungsfreien Sitzposition.A saddle is preferably attached as a seat on the top of the frame head. This arrangement offers the advantage of stable attachment the seat, which is supported at the point where all forces acting on the watercraft meet. In addition, due to its central location due to its construction, the frame head will generally be located approximately vertically above the center of gravity of the vehicle. The design of the seat as a saddle also offers the advantage of an upright and fatigue-free sitting position.

Weiterhin ist in einer Fortbildung der Erfindung vorgesehen, daß der Sattel an seiner Vorderseite einen Haltegriff aufweist.
Er gestattet der auf dem Sattel sitzenden Person eine subjektiv und objektiv stabile Sitzposition einzunehmen.In a further development of the invention it is provided that the saddle has a handle on its front.
It allows the person sitting on the saddle to take a subjectively and objectively stable sitting position.

Besonders bevorzugt ist an der Unterseite des Rahmenkopfs eine Gabel zu befestigen, deren beide Gabelarme an ihren unteren Enden von einer Achse durchgriffen werden, an der endseitig mittels Kurbelstangen Pedale befestigt sind und daß zwischen den Gabelarmen etwa mittig auf der Achse und mit dieser starr verbunden ein Schaufelrad angebracht ist.
Der mit dieser Anordnung verbundene Vorteil liegt im einfachen und unkomplizierten Aufbau der Antriebsmechanik, die direkt mit der Pedalerie verbunden ist. Es mag sein, daß ein Schaufelrad gegenüber einem Schraubenantrieb einen geringeren Wirkungsgrad aufweist. Dieser Nachteil wird jedoch durch den Vorteil des einfacheren Aufbaus aufgewogen.It is particularly preferred to attach a fork to the underside of the frame head, the two fork arms of which are penetrated at their lower ends by an axle, on the end of which pedals are fastened by means of crank rods and that between the fork arms are approximately centrally on the axle and rigidly connected to it Paddle wheel is attached.
The advantage associated with this arrangement is the simple and uncomplicated construction of the drive mechanism, which is directly connected to the pedals. It may be that a paddle wheel is less efficient than a screw drive. However, this disadvantage is offset by the advantage of the simpler structure.

In einer weiteren Ausbildung der Erfindung wird außerdem vorgeschlagen, daß das Schaufelrad aus einer mit der Achse fest verbundenen, annähernd kreisförmigen, von der Achse im Mittelpunkt durchgriffenen Scheibe und Schaufelblättern besteht, die mit der Scheibe dergestalt fest verbunden sind, daß sie von ihrem Mittelpunkt radial nach außen weisen.In a further embodiment of the invention it is also proposed that the paddle wheel consists of an approximately circular disk which is fixedly connected to the axle and penetrated by the axle in the center, and which is firmly connected to the disk in such a way that it is radial from its center point outwards.

Zur Verbesserung der Manövrierfähigkeit ist ein Ruderblatt zwischen den Rümpfen in das Wasser eintauchend angeordnet. Dessen Verschwenkung erfolgt und wird bestimmt durch einen von dem auf dem Sattel sitzenden Benutzer aus erreichbaren Lenker oder Knauf, bei dessen Verschwenken oder Verdrehen die Position des Ruderblatts geändert wird. Zur Steurung kann auch der Haltegriff genutzt werden.Die Übertragung der Bewegung auf das Ruderblatt erfolgt auf beliebige Weise z.B. durch ein Kabel, ein Gestänge, eine Welle.To improve maneuverability, a rudder blade is placed between the hulls soaking in the water. Its pivoting takes place and is determined by a handlebar or knob that can be reached by the user sitting on the saddle, the pivoting or twisting of which changes the position of the rudder blade. The handle can also be used for control. The movement is transferred to the rudder blade in any way, e.g. through a cable, a linkage, a shaft.

In der konkreten baulichen Realisierung ist darüber hinaus bevorzugt, daß die beiden Rümpfe durch weitere Traversen unmittelbar miteinander verbunden sind.In the concrete structural implementation, it is also preferred that the two hulls are directly connected to one another by further cross members.

Der mit dieser Anordnung erzielte Vorteil besteht in einer erhöhten Stabilität des gesamten Wasserfahrzeugs gegen Verwindungen, die etwa bei leichtem Wellenschlag eintreten könnten.The advantage achieved with this arrangement is an increased stability of the entire watercraft against twists that could occur, for example, with a slight wave.
