Definitions
- the invention relates to a surfboard with a seat or standing surface for a water sports enthusiast, a jet drive and a swiveling nozzle.
- Water sports equipment with a jet drive and swiveling nozzle are in the form of jet skis or surfboards, the latter for example from the DE 20 2011 051 071 known.
- the controllable surfboard shown in the last-mentioned utility model has a surfboard into which a jet drive is integrated.
- the jet drive has a swiveling nozzle for water sucked into an underwater surface of the surfboard. By swiveling the nozzle, the surfboard can be maneuvered into a right or left curve.
- the nozzle can be controlled via a control held in the water sports enthusiast's hand or via a gyro sensor arranged in the surfboard. In the second case, the feed is controlled by a manual control.
- the disadvantage of the known water sports device is the fact that it can no longer be controlled while cornering if the advance of the jet drive is too low or is switched off. The water sports device then only performs a lateral drift movement.
- a jet ski is disclosed with a pivotable nozzle and pivotable fins arranged laterally next to the pivotable nozzle and, on the other hand, a jet ski with a fixed-position nozzle and with fixed-position fins arranged on the nozzle itself.
- the disadvantage of the jet ski is the fact that the control is relatively complex or only insufficiently effective.
- the invention makes use of the idea, in addition to the jet drive, which enables cornering by pivoting the nozzle during operation, to provide a pivotable fin that enables cornering even when the jet drive is not in operation or is not in operation with sufficient intensity and from the Jet drive nozzle, water is not sprayed out.
- An axis of rotation is expediently provided about which the nozzle is pivotably arranged and about which the fin is also pivotably arranged.
- the fin and the nozzle are favorably connected to one another and to one another in a fixed position, and a pivoting device of the nozzle is also the pivoting device of the fin.
- the Finn is in Operation immersed in the water. Even if there is no propulsion through the nozzle, the surboard can still be steered by the fin immersed in the water.
- a standing or sitting surface is provided for the water sports enthusiast, and the axis of rotation is arranged perpendicular to the standing or sitting surface.
- a sitting or standing surface is to be understood here very generally as a device on which the water sports enthusiast is while exercising the sport.
- the invention relates to surfboards in which a jet drive is integrated.
- the fin has a rear control surface arranged behind the axis of rotation in the direction of travel of the surfboard and a front control surface arranged in front of the axis of rotation in the direction of travel.
- the two control surfaces together form the control surface of the fin. Because the axis of rotation does not run along the outer edges or completely outside of the control surface, but is passed through the control surface of the fin at a distance from the outer edges of the fins inwards, a mutually canceling torque is exerted on both control surfaces when the fin is positioned transversely, see above that the force acting on the pivot control of the fin and the nozzle is minimized.
- the fin is conveniently attached to a water side of the nozzle by means of nylon screws.
- the fin is attached directly to the axis of rotation by means of a nylon screw and directly to the water side of the nozzle by means of another nylon screw.
- Nylon screws are inexpensive and, even if they should break, they can be replaced quickly and easily.
- the nylon screws are designed as predetermined breaking points of the fin, so that even if the surfboard is pulled with its water underside on sand or in very shallow water and the fin breaks off, the fin itself is not damaged, but breaks on both of them inexpensive replaceable nylon screws from the nozzle.
- the surfboard according to the invention 1 in Fig. 1 shows a standing surface 2 for a water sports enthusiast, which is arranged horizontally during operation.
- a bow 3 of the surfboard 1 which is in Fig. 1 is arranged on the right, an eyelet 4 is provided for a tether 6.
- One end of the tether 6 is knotted into the eyelet 4.
- a controller 7 is tied.
- the control 7 comprises a wireless radio connection or a Bowden cable or a connection with a cable to a drive 8 integrated in the surfboard.
- the radio connection is shown by the dashed line.
- a foot strap 9 is attached to the standing surface 2 of the surfboard 1.
- the water sports enthusiast can put one foot into the foot loop 9 to practice the sport and grasp and hold the control 7 with one hand and get additional hold on the surfboard 1 through the tether 6.
- the controller 7 in this case only serves to control the strength of the propulsion of the surfboard, i.e. the speed of the surfboard 1.
- the controller can include a gyroscope function so that the propulsion is changed via a tilting movement or as a lever, a type of joystick becomes.
- a gyro sensor 11 is provided in the surfboard, which registers tilting movements about a longitudinal direction L of the surfboard 1.
- the gyro sensor 11 is connected to a pivoting device 12, 17, 18 which acts on a nozzle 13 arranged in a rear 14 and pivots the nozzle 13 in a plane parallel to the standing surface 2.
- the swivel drive comprises an arm 17 which is arranged on the nozzle 13 and to which an adjusting rod 18 is articulated.
- the control rod 18 is connected to a servomotor 12.
- the servomotor 12 enables the adjusting rod 18 to be extended and retracted, so that the nozzle 13 can pivot via the arm 17 Fig. 1 can be done in the drawing plane.
- Fig. 2 shows the surfboard 1 in Fig. 1 in a bottom view.
- an underwater surface 16 of the surfboard 1 is shown.
- the underwater surface 16 has an inlet 19 for the water.
- water is used according to Fig. 3 , sucked in on the underwater surface 16 of the surfboard 1 and accelerated by means of a propeller 21 and pushed out of the nozzle 13.
- the surfboard 1 can make a right or left curve.
- Fig. 3 shows the stern 4 of the surfboard 1 in FIG Fig. 1 and 2 in a sectional view.
- water is sucked in through the inlet 19 on the underwater surface 16 and accelerated by means of the propeller 21, which is provided in a water channel between the inlet 19 and the nozzle 13, and pushed out of the nozzle 13.
- the propulsion of the surfboard 1 consists of the recoil that forms as a result of being pushed out.
- the nozzle 13 is mounted pivotably about an axis of rotation D on the rear 14 of the surfboard 1 and closes off the water channel on the rear side.
- a fin 23 is attached to the nozzle 13. The fin 23 can be pivoted with the nozzle 13.
- the fin 23 is on the one hand screwed to the axis of rotation D of the nozzle 13 with a nylon screw 22a and on the other hand is screwed to a water side of the nozzle 13 at a further point by means of a further nylon screw 22b.
- a further nylon screw 22b it can also be fixed to the nozzle 13 of the jet drive by a shape of the fin 23 adapted to the nozzle 13.
- the fin 23 can have an approximately U-profile shaped receptacle on its side facing away from the water, which is clicked onto the nozzle 13.
- the fin 23 can also encase the nozzle 13 in some other way.
- the fin 23 executes the pivoting movement of the nozzle 13 about the same axis of rotation D as the nozzle 13.
- the nozzle 13 has a rear control surface 23a arranged behind the axis of rotation D in the direction of travel of the surfboard 1 and a front control surface 23b arranged in front of the axis of rotation D in the direction of travel.
- the two control surfaces 23a, 23b form the entire control surface of the fin 23.
- the fin 23 makes it possible to carry out a controlled cornering, even if the jet drive does not generate any propulsion, that is, no water is sprayed out of the nozzle 13.
- the fin 23 is supported by two further fins 24a, 24b according to FIG Fig. 2 , which also stabilize the ride of the surfboard 1 and generate additional buoyancy due to their outwardly curved shape.

Description
Die Erfindung betrifft ein Surfbrett mit einer Sitz- oder Standfläche für einen Wassersportler, einem Jetantrieb und einer schwenkbaren Düse.The invention relates to a surfboard with a seat or standing surface for a water sports enthusiast, a jet drive and a swiveling nozzle.
Wassersportgeräte mit einem Jetantrieb und schwenkbarer Düse sind in Form von Jetski oder von Surfbrettern, letztere beispielsweise aus der
Nachteilig an dem bekannten Wassersportgerät ist die Tatsache, dass während einer Kurvenfahrt nicht mehr gesteuert werden kann, wenn der Vorschub des Jetantriebs zu gering oder ausgeschaltet ist. Das Wassersportgerät führt dann lediglich eine seitliche Driftbewegung aus.The disadvantage of the known water sports device is the fact that it can no longer be controlled while cornering if the advance of the jet drive is too low or is switched off. The water sports device then only performs a lateral drift movement.
In der
Aus der
Es ist daher Aufgabe der vorliegenden Erfindung, ein Surfbrett der eingangs genannten Art zur Verfügung zu stellen, das eine verbesserte Kurvenfahrt ermöglicht.It is therefore the object of the present invention to provide a surfboard of the type mentioned at the outset which enables improved cornering.
Die Aufgabe wird durch ein eingangs genanntes Surfbrett mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved by a surfboard mentioned at the beginning with the characterizing features of
Die Erfindung macht von der Idee Gebrauch, zusätzlich zum Jetantrieb, der während des Betriebs eine Kurvenfahrt durch Verschwenken der Düse ermöglicht, eine verschwenkbare Finne vorzusehen, die die Kurvenfahrt auch dann ermöglicht, wenn der Jetantrieb nicht oder nicht hinreichend stark in Betrieb ist und aus der Düse des Jetantriebs kein Wasser herausgespritzt wird.The invention makes use of the idea, in addition to the jet drive, which enables cornering by pivoting the nozzle during operation, to provide a pivotable fin that enables cornering even when the jet drive is not in operation or is not in operation with sufficient intensity and from the Jet drive nozzle, water is not sprayed out.
Günstigerweise ist eine Drehachse vorgesehen, um die die Düse schwenkbar angeordnet ist und um die auch die Finne schwenkbar angeordnet ist. Die Finne und die Düse sind günstigerweise miteinander und zueinander positionsfest verbunden, und eine Schwenkeinrichtung der Düse ist auch die Schwenkeinrichtung der Finne. Die Finne ist im Betrieb in das Wasser eingetaucht. Selbst wenn kein Vortrieb durch die Düse erfolgt, ist immer noch durch die in das Wasser eingetauchte Finne eine Lenkung des Surbretts möglich.An axis of rotation is expediently provided about which the nozzle is pivotably arranged and about which the fin is also pivotably arranged. The fin and the nozzle are favorably connected to one another and to one another in a fixed position, and a pivoting device of the nozzle is also the pivoting device of the fin. The Finn is in Operation immersed in the water. Even if there is no propulsion through the nozzle, the surboard can still be steered by the fin immersed in the water.
In einer bevorzugten Ausführungsform der Erfindung ist eine Steh- oder Sitzfläche für den Wassersportler vorgesehen, und die Drehachse ist senkrecht zur Steh- oder Sitzfläche angeordnet. Unter einer Sitz- oder Stehfläche ist hier sehr allgemein eine Einrichtung zu verstehen, auf der sich der Wassersportler während der Ausübung des Sportes befindet.In a preferred embodiment of the invention, a standing or sitting surface is provided for the water sports enthusiast, and the axis of rotation is arranged perpendicular to the standing or sitting surface. A sitting or standing surface is to be understood here very generally as a device on which the water sports enthusiast is while exercising the sport.
Die Erfindung bezieht sich auf Surfbretter, in die ein Jetantrieb integriert ist.The invention relates to surfboards in which a jet drive is integrated.
In einer weiteren bevorzugten Ausführungsform der Erfindung weist die Finne eine in Fahrtrichtung des Surfbrettes hinter der Drehachse angeordnete hintere Steuerfläche und eine in Fahrtrichtung vor der Drehachse angeordnete vordere Steuerfläche auf. Die beiden Steuerflächen bilden zusammen die Steuerfläche der Finne aus. Dadurch, dass die Drehachse nicht entlang äußerer Ränder oder vollständig außerhalb der Steuerfläche verläuft, sondern von den äußeren Rändern der Finnen nach innen beabstandet durch die Steuerfläche der Finne hindurchgeführt ist, wird beim Querstellen der Finne auf beide Steuerflächen ein sich gegenseitig aufhebendes Drehmoment ausgeübt, so dass die auf die Schwenksteuerung der Finne und der Düse wirkende Kraft minimiert wird.In a further preferred embodiment of the invention, the fin has a rear control surface arranged behind the axis of rotation in the direction of travel of the surfboard and a front control surface arranged in front of the axis of rotation in the direction of travel. The two control surfaces together form the control surface of the fin. Because the axis of rotation does not run along the outer edges or completely outside of the control surface, but is passed through the control surface of the fin at a distance from the outer edges of the fins inwards, a mutually canceling torque is exerted on both control surfaces when the fin is positioned transversely, see above that the force acting on the pivot control of the fin and the nozzle is minimized.
Günstigerweise ist die Finne mittels Nylonschrauben an einer Wasserseite der Düse befestigt. Die Finne ist zum einen mittels einer Nylonschraube direkt an der Drehachse und zum anderen mittels einer weiteren Nylonschraube direkt an der Wasserseite der Düse befestigt. Nylonschrauben sind kostengünstig erhältlich und können, auch wenn sie brechen sollten, schnell und einfach ersetzt werden. Die Nylonschrauben sind gleichsam als Sollbruchstellen der Finne ausgebildet, so dass, auch wenn das Surfbrett mit seiner Wasserunterseite auf Sand gezogen wird oder in sehr flachem Wasser fährt und die Finne abbrechen sollte, die Finne selbst eben nicht beschädigt wird, sondern sie bricht an den beiden kostengünstigen ersetzbaren Nylonschrauben von der Düse ab.The fin is conveniently attached to a water side of the nozzle by means of nylon screws. The fin is attached directly to the axis of rotation by means of a nylon screw and directly to the water side of the nozzle by means of another nylon screw. Nylon screws are inexpensive and, even if they should break, they can be replaced quickly and easily. The nylon screws are designed as predetermined breaking points of the fin, so that even if the surfboard is pulled with its water underside on sand or in very shallow water and the fin breaks off, the fin itself is not damaged, but breaks on both of them inexpensive replaceable nylon screws from the nozzle.

Das erfindungsgemäße Surfbrett 1 in
Im Surfbrett ist ein Gyrosensor 11 vorgesehen, der Kippbewegungen um eine Längsrichtung L des Surfbrettes 1 registriert. Der Gyrosensor 11 ist mit einer Schwenkeinrichtung 12, 17, 18 verbunden, die auf eine in einem Heck 14 angeordnete Düse 13 wirkt und die Düse 13 in einer Ebene parallel zur Standfläche 2 verschwenkt.A
Der Schwenkantrieb umfasst einen an der Düse 13 angeordneten Arm 17, an dem eine Stellstange 18 angelenkt ist. Die Stellstange 18 ist mit einem Servomotor 12 verbunden. Der Servomotor 12 ermöglicht ein Ein- und Ausfahren der Stellstange 18, sodass über den Arm 17 eine Schwenkbewegung der Düse 13 in
Die Finne 23 führt um dieselbe Drehachse D wie die Düse 13 die Schwenkbewegung der Düse 13 mit aus. Die Düse 13 weist eine in Fahrtrichtung des Surfbrettes 1 hinter der Drehachse D angeordnete hintere Steuerfläche 23a und eine in Fahrtrichtung vor der Drehachse D angeordnete vordere Steuerfläche 23b auf. Die beiden Steuerflächen 23a, 23b bilden die gesamte Steuerfläche der Finne 23 aus. Beim Schrägstellen der Finne 23 im Wasser während der Kurvenfahrt wird somit eine Kraft sowohl auf die hintere 23a als auch auf die vordere Steuerfläche 23b ausgeübt, und die sich dadurch bildenden Drehmomente auf die Drehachse D heben sich im Wesentlichen gegenseitig vollständig auf. Dadurch muss der die Schwenkbewegung ausführende Servomotor 12 weniger Kraft aufwenden, um die Schwenkbewegung auszuführen.The
Die Finne 23 ermöglicht es, eine gesteuerte Kurvenfahrt durchzuführen, auch wenn der Jetantrieb keinen Vortrieb erzeugt, also kein Wasser aus der Düse 13 herausgespritzt wird. Unterstützt wird die Finne 23 durch zwei weitere Finnen 24a, 24b gemäß
