Description

Die Erfindung betrifft ein Wasserfahrzeug nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a watercraft according to the preamble of claim 1.

Es sind bereits mehrere Motor-Anbausätze für Surfbretter bekannt und auf dem Markt erhältlich, die dazu dienen sollen, das Surfbrett bei Windflaute motorisch anzutreiben. Allen diesen Motor-Anbausätzen sind die Nachteile gemeinsam, daß das Surfbrett zur Anbringung des Anbausatzes verändert werden muß, insbesondere Befestigungslöcher vorzusehen sind, daß ihr Transport aufgrund der Sperrigkeit oder der Vielzahl an Einzelteilen schwierig oder zumindest unbequem ist und daß schließlich lediglich ein motorischer Notantrieb erreicht wird, nicht aber ein tatsächlich fahrtüchtiges Motor-Wasserfahrzeug.Several motor mounting kits for surfboards are already known and available on the market, which are intended to drive the surfboard by motor when the wind is calm. All these motor mounting kits have the disadvantages in common that the surfboard must be changed to attach the mounting kit, in particular mounting holes must be provided, that their transport is difficult or at least uncomfortable due to the bulk or the large number of individual parts, and that ultimately only an emergency motor drive is achieved will, but not an actually roadworthy motor watercraft.

Aufgabe der vorliegenden Erfindung ist es deshalb, den Motor-Anbausatz so zu verbessern, daß er leicht zu transportieren und ohne Veränderung des Surfbretts an diesem anbringbar ist, dabei aber ein stabiles und äußerst fahrtüchtiges Motor-Wasserfahrzeug entsteht. Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Hauptanspruchs.The object of the present invention is therefore to improve the motor mounting kit in such a way that it is easy to transport and can be attached to the surfboard without changing it, but a stable and extremely roadworthy motor watercraft is produced in the process. The solution to this problem results from the characterizing features of the main claim.

Gemäß der Erfindung besteht also der Motor-Anbausatz im wesentlichen lediglich aus zwei leicht transportierbaren Einheiten, die einfach und schnell am Surfbrett anbringbar sind, ohne daß am Surfbrett selbst besondere Maßnahmen getroffen werden müssen. Trotzdem ergibt sich ein äußerst stabiler Aufbau, und es entsteht ein Motor-Wasserfahrzeug, auf dem der Fahrer ähnlich wie auf einem Motorrad sitzt und lenkt und das insbesondere aufgrund der Ausleger-Schwimmer äußerst sicher ist. Die Fahrtüchtigkeit ist derart, daß das Fahrzeug beispielsweise auch auf Flüssen einwandfrei gefahren werden kann, ohne daß der Fahrer einer langjährigen Übung bedarf.According to the invention, the motor mounting kit essentially consists of only two easily transportable units that can be attached to the surfboard easily and quickly, without special measures having to be taken on the surfboard itself. Nevertheless, the structure is extremely stable, and a motorized watercraft is created on which the driver resembles sits and steers on a motorcycle and that is extremely safe, especially due to the boom floats. The ability to drive is such that the vehicle can be driven perfectly even on rivers, for example, without the driver needing many years of practice.

Besonders zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Particularly expedient configurations of the invention are characterized in the subclaims.

Auf der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt. Es zeigen:

  • Fig. 1 eine Seitenansicht des Wasserfahrzeugs und
  • Fig. 2 eine Draufsicht auf das Wasserfahrzeug von Fig. 1.
In the drawing, an embodiment of the invention is shown for example. Show it:
  • Fig. 1 is a side view of the watercraft and
  • FIG. 2 is a top view of the watercraft of FIG. 1.

Das dargestellte Wasserfahrzeug besteht im wesentlichen aus drei Elementen, nämlich einem Surfbrett 10, einer im ganzen mit 20 bezeichneten Sitz-Einheit und einer im ganzen mit 30 bezeichneten Motorspiegel-Einheit.The watercraft shown consists essentially of three elements, namely a surfboard 10, a seat unit designated as a whole with 20 and a motor mirror unit designated as a whole with 30.

Bei dem Surfbrett 10 handelt es sich um ein marktübliches Wind-Surfbrett mit Mast-Sackloch 11 und drei Durchbohrungen 12 zum Anschrauben einer Finne. Mast und Finne sind auf der Zeichnung nicht gezeigt.The surfboard 10 is a commercially available wind surfboard with a mast blind hole 11 and three through holes 12 for screwing on a fin. The mast and fin are not shown in the drawing.

Die Sitzeinheit 20 weist einen Rahmenkörper 21 auf, der in Seitenansicht in etwa die Form einer um 90° nach links gekippten Ziffer "2" hat und dessen - in Surfbrett-Richtung gesehen - Vorderteil 21a einer Lenker-Tragsäule darstellt. Auf dem Rahmen 21 ist ein Sitzbrett 22 befestigt. Am Oberende der Lenker-Tragsäule 21a befindet sich ein um die Tragsäulenachse schwenkbarer Steuerlenker 23. Ferner ist am Rahmenkörper 21 ein Treibstofftank 24 angebracht, derart, daß dann, wenn eine Person auf dem Sitzbrett 22 sitzt, der Tank 24 sich zwischen deren Knien befindet, ähnlich wie bei einem Motorrad. Die Sitzeinheit 20 ist ferner mit beidseits abstehenden Auslegerarmen 25 und 26 versehen, wobei jeder Auslegerarm 25, 26 aus zwei gegeneinander verstrebten Rohren 25a, 25b bzw. 26a, 26b besteht. Dabei sind die jeweils unteren Rohre 25a, 26a im unteren Bereich, die beiden oberen Rohre 25b, 26b mit Abstand darüber im oberen Bereich der Lenker-Tragsäule 21a schwenkbar befestigt; an ihren freien Außenenden laufen die Rohrpaare 25a, 25b bzw. 26a, 26b zusammen, so daß sich ein Dreieck-Gestänge ergibt. Wesentlich dabei ist, daß die Lenker-Tragsäule 21a schräg zur Vertikalen verläuft, so daß auch die Dreieck-Ebenen der beiden Auslegerarme 25 und 26 zur Vertikalen geneigt sind. An den beiden Aussenenden der Auslegerarme 25 und 26 sind Schwimmer 27 und 28 angelenkt, derart, daß die Schwimmer begrenzt um die Vertikale schwenkbar sind, und zwar parallel zur Längsachse des Surfbretts (Fig. 2). Die gesamte Sitzeinheit mit Auslegerarm und Schwimmern ist mittels eines Befestigungselements 29 im Mastloch 11 des Surfbretts 10 verankerbar, wobei es sich um eine Schraub-, Klemm-, Spreiz- oder Bajonettverbindung handeln kann.The seat unit 20 has a frame body 21 which, in a side view, has approximately the shape of a number "2" tilted to the left by 90 ° and whose front part 21a, as seen in the direction of the surfboard, represents a handlebar support column. A seat board 22 is attached to the frame 21. At the upper end of the handlebar support column 21a there is a control link 23 which can be pivoted about the support column axis. Furthermore, a fuel tank 24 is located on the frame body 21 attached, such that when a person sits on the seat board 22, the tank 24 is between their knees, similar to a motorcycle. The seat unit 20 is further provided with cantilever arms 25 and 26 projecting on both sides, each cantilever arm 25, 26 consisting of two mutually braced tubes 25a, 25b and 26a, 26b. The respective lower tubes 25a, 26a are pivotally attached in the lower area, the two upper tubes 25b, 26b at a distance above it in the upper area of the handlebar support column 21a; at their free outer ends, the tube pairs 25a, 25b and 26a, 26b converge, so that a triangular linkage results. It is essential that the handlebar support column 21a extends obliquely to the vertical, so that the triangular planes of the two extension arms 25 and 26 are inclined to the vertical. Floats 27 and 28 are articulated on the two outer ends of the cantilever arms 25 and 26 in such a way that the floats can be pivoted to a limited extent about the vertical, parallel to the longitudinal axis of the surfboard (FIG. 2). The entire seat unit with extension arm and floats can be anchored by means of a fastening element 29 in the mast hole 11 of the surfboard 10, which can be a screw, clamp, spread or bayonet connection.

Die Motorspiegel-Einheit 30 weist einen Motorspiegel 31 auf, an dessen Oberkante ein marktüblicher Außenbordmotor 32 mit Antriebschraube 33 schwenkbar angelenkt ist. Im unteren Bereich des Spiegels 31 steht von diesem ein Halterungsschuh 33 im wesentlichen senkrecht ab, wobei Spiegel 31 und Schuh 33 durch ein Gestänge 34 gegeneinander verstrebt sind. Am untersten Ende des Spiegels 31 befindet sich eine im wesentlichen parallel zum Befestigungsschuh 33 vorspringende Klemmnase 36, deren Form in etwa derjenigen einer kleinen Finne entspricht. Der Abstand zwischen der Klemmnase 36 und dem Befestigungsschuh 33 ist in etwa gleich der Dicke des Surfbretts 10 bzw. ist geringfügig größer. Zur Anbringung der Motorspiegel-Einheit 30 am Surfbrett 10 wird der Schuh 33 von hinten her auf des Hinterende des Surfbretts 10 aufgeschoben, bis dessen Hinterkante an dem Motorspiegel 31 anliegt. Durch die Klemmnase 36 ist dann bereits eine gewisse Klemmhalterung der Einheit 30 erreicht. Zusätzlich wird nun der Schuh 33 mittels nicht-gezeichneter Befestigungselemente, welche in die Durchbohrungen 12 greifen, auf der Surfbrett-Oberseite befestigt; es kann sich auch hier um eine Schraub-, Klemm-, Spreiz- oder Bajonettverbindung handeln. Die beiden auf dem Surfbrett angebrachten Einheiten 20 und 30 werden gegeneinander verspannt, und zwar durch Lenker 40 und 41, die mit ihrem einen Ende gemeinsam an der Oberseite des Halterungsschuhs 33 der Einheit 30 und mit ihren anderen Enden an den Auslegerarmen 25 und 26 der Einheit 20 angelenkt sind, und zwar im Bereich der Außenenden desselben. Die Anlenkung der Lenker 40, 41 ist an einem oder an beiden Enden lösbar gestaltet, etwa durch eine Einhängverbindung, oder die Lenker sind mittels eines lösbaren Verbindungselements unterteilt; wesentlich ist nur, daß die beiden Einheiten 20 und 30 voneinander getrennt werden können. Im zusammengebauten Zustand bilden die Lenker 40, 41 zusammen mit den Auslegerarmen 25, 26 ein Trapez-Gestänge (Fig.2), das für eine ausgezeichnete Stabilität zwischen Surfbrett, Sitzeinheit und Motorspiegel-Einheit sorgt.The motor mirror unit 30 has a motor mirror 31, on the upper edge of which a commercially available outboard motor 32 is pivotably articulated with a drive screw 33. In the lower region of the mirror 31, a mounting shoe 33 projects from it essentially vertically, the mirror 31 and shoe 33 being braced against one another by a linkage 34. At the lowest end of the mirror 31 there is a clamping lug 36 projecting essentially parallel to the fastening shoe 33, the shape of which roughly corresponds to that of a small fin. The distance between the clamping lug 36 and the fastening shoe 33 is approximately equal to the thickness of the surfboard 10 or is slightly larger. To attach the motor mirror unit 30 to the surfboard 10 the shoe 33 is pushed from the rear onto the rear end of the surfboard 10 until its rear edge lies against the motor mirror 31. A certain clamping bracket of the unit 30 is then already achieved by the clamping lug 36. In addition, the shoe 33 is now fastened to the top of the surfboard by means of fastening elements (not shown) which engage in the through holes 12; it can also be a screw, clamp, expansion or bayonet connection. The two units 20 and 30 mounted on the surfboard are braced against one another by means of links 40 and 41, which have one end together on the top of the mounting shoe 33 of the unit 30 and the other ends on the extension arms 25 and 26 of the unit 20 are articulated, in the area of the outer ends of the same. The linkage of the links 40, 41 is designed to be detachable at one or both ends, for example by means of a hook-in connection, or the links are divided by means of a detachable connecting element; it is only essential that the two units 20 and 30 can be separated from one another. In the assembled state, the handlebars 40, 41 together with the extension arms 25, 26 form a trapezoidal linkage (FIG. 2), which ensures excellent stability between the surfboard, seat unit and engine mirror unit.

Letztlich ist noch eine Verbindung zwischen Steuerlenker 23 und Außenbordmotor 32 herzustellen, was durch bei 15 angedeutete Bowdenzüge geschieht. Genauer gesagt, am Steuerlenker 23 befindet sich, wie bei einem Motorrad, ein Gasdrehgriff 23a, der über einen der Bowdenzüge 15 am Gashebel des Außenbordmotors angreift, so daß vom Steuerlenker 23 aus die Motorgeschwindigkeit gesteuert werden kann, und außerdem befinden sich am Steuerlenker mit Abstand von dessen Mittelpunkt Bowdenzüge, die derart am Außenbordmotor angreifen, daß eine Drehbewegung des Steuerlenkers eine entsprechende Drehbewegung des Außenbordmotors zur Folge hat, gegebenenfalls mit einer vorbestimmten Über- bzw. Untersetzung. Die lösbare Anbringung dieser Bowdenzüge kann auf verschiedene Weise erfolgen, jedoch hat sich als vorteilhaft erwiesen, die Bowdenzüge für die Steuerung über Kreuz zu führen. Selbstverständlich können an der Sitzeinheit 20 auch Führungselemente zum Führen der Bowdenzüge 15 vorgesehen sein. Darüber hinaus ist es zwecks Verhinderung der für die Lenkung erforderlichen Kräfte möglich, am Außenbordmotor eine Lenker-Querstange anzubringen, an welcher dann die Bowdenzüge für die Steuerung befestigt sind.Ultimately, a connection between control arm 23 and outboard motor 32 still has to be established, which is done by means of Bowden cables indicated at 15. More specifically, on the control arm 23 there is, as in a motorcycle, a throttle grip 23a which engages the throttle lever of the outboard motor via one of the Bowden cables 15 so that the engine speed can be controlled from the control arm 23, and there are also at a distance on the control arm Bowden cables, which act on the outboard motor in such a way that a rotary movement of the control arm results in a corresponding rotary movement of the outboard motor, if necessary with a predetermined ratio. The detachable attachment of these Bowden cables can be done in different ways, but it has proven to be advantageous to cross the Bowden cables for control. Of course, guide elements for guiding the Bowden cables 15 can also be provided on the seat unit 20. In addition, in order to prevent the forces required for steering, it is possible to attach a handlebar crossbar to the outboard motor, to which the Bowden cables for the control are then attached.

Das beschriebene Wasserfahrzeug kann als übliches Wind-Surfbrett verwendet werden, wobei am Brett 10 ein Segelmast und eine Finne angebracht werden. Für die Verwendung als Motor-Wasserfahrzeug werden anstelle von Mast und Finne die Sitzeinheit 20 und die Motorspiegel-Einheit 30 in der beschriebenen Weise am Brett 10 angebracht und durch die Lenker 40, 41 sowie die Bowdenzüge 15 die erwähnten Verbindungen hergestellt. Damit entsteht ein Wasserfahrzeug, das ähnlich wie auf der Straße ein Motorrad auf der Wasseroberfläche gefahren werden kann. Der Transport des Motor-Anbausatzes bereitet keinerlei Schwierigkeiten, weil er im wesentlichen nur aus zwei Teilen besteht, nämlich der Sitzeinheit 20, wobei die Auslegerarme an die Einheit angeklappt werden, und der Motorspiegel-Einheit 30. Die Lenker 40, 41 werden, je nach Befestigungsart, an die Einheit 20 oder die Einheit 30 angeklappt bzw. gesondert transportiert; dasselbe gilt entsprechend für die Bowdenzüge 15.The watercraft described can be used as a conventional wind surfboard, with a sail mast and a fin being attached to the board 10. For use as a motor watercraft, the seat unit 20 and the motor mirror unit 30 are attached to the board 10 in the manner described, instead of the mast and fin, and the connections mentioned are established by the handlebars 40, 41 and the Bowden cables 15. This creates a watercraft that can be driven on the water surface in a similar way to a motorcycle on the road. The transportation of the motor mounting kit presents no difficulties, because it essentially consists of only two parts, namely the seat unit 20, with the extension arms being folded onto the unit, and the motor mirror unit 30. The links 40, 41 become, depending on Type of fastening, folded onto the unit 20 or the unit 30 or transported separately; the same applies accordingly to the Bowden cables 15.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern es sind diesem gegenüber zahlreiche Abwandlungen möglich, ohne den Bereich der Erfindung zu verlassen. Dies gilt für die Formgestaltung der Sitzeinheit 20 und der Motorspiegel-Einheit 30 und die Verbindungselemente für die Gestänge und Bowdenzüge. Die Befestigungselemente für die beiden Einheiten 20 und 30 am Surfbrett 10 sind den Gegebenheiten des Surfbretts anzupassen, was jedoch leicht geschehen kann, unabhängig davon, ob das Surfbrett ein Sackloch oder eine Schiene für den Mast, Halterungslöcher für die Finne, Halterungslöcher oder eine Schiene für die Finne oder Halterungslöcher für Stehschlaufen aufweist.The invention is not limited to the exemplary embodiment shown, but numerous modifications are possible compared to it without leaving the scope of the invention. This applies to the shape of the seat unit 20 and the motor mirror unit 30 and the connecting elements for the linkage and Bowden cables. The fasteners for the two units 20 and 30 on the surfboard 10 can be adapted to the conditions of the surfboard, but this can be done easily, regardless of whether the surfboard is a blind hole or a rail for the mast, mounting holes for the fin, mounting holes or a rail for the fin or mounting holes for standing loops.
